Technical field
[001] The present invention relates to an indoor unit of an air conditioning unit. Background Technique
[002] As an indoor unit of an air conditioning unit, it is, as described in patent citation 1 (JP-ANo. 2002-349892), for example, an indoor unit of an air conditioning unit where several air outlets are arranged . In this indoor unit of an air conditioning unit, a wide range of a target space can be conditioned by the air conditioning expelled from each of the various air outlets.
[003] However, in the indoor unit of an air conditioning unit of patent citation 1 (JP-A No. 2002-349892), in a case where the target area in which the air conditioning from a predetermined air outlet is expelled is next to a side wall in a room or in a case where there is a user who does not like the feeling of a draft, a closing member or the like becomes separately necessary in order to maintain the extent to which air is expelled from this outlet. air goes down or stops it.
[004] In connection with this, in an indoor unit of an air conditioning unit described in the citation of patent 2 (JP-ANo. 2007- 285652), a technology is proposed that reduces the volume of air conditioning expelled from a specific outlet. air causing a horizontal flap that adjusts the airflow direction of the air conditioner to rotate to block the entire air outlet. Summary of the invention Technical problem
[005] However, in the indoor unit of the air conditioning unit described in patent citation 2 (JP-A No. 2007-285652), it is difficult to completely block the air outlet with the horizontal flap, and it is easy for a temperature difference appear between the surface of the horizontal flap that the air conditioning strikes and the surface of the horizontal flap in the environment within which the air whose temperature has not yet adjusted the strokes. When a temperature difference arises between a surface and the opposite surface of the horizontal flap in this way, it ends up becoming easier for dew condensation to form on the front surface of the horizontal flap.
[006] The present invention was made in view of the circumstances described above, and it is a problem of the present invention to provide an indoor unit of an air conditioning unit that can reduce the volume of air expelled from any air outlet from several air outlets while suppresses dew condensation without using a new part. Solution to the problem
[007] An indoor unit of an air conditioning unit of a first aspect of the invention is an indoor unit of an air conditioning unit that is fixed in relation to the ceiling, the indoor unit including a housing of the indoor unit, direction adjustment plates of the airflow, and an airflow direction adjustment control unit. The housing of the indoor unit has an air inlet and several air outlets. The various air flow direction adjustment plates are arranged on the air outlet respectively. The air flow direction adjustment plates can, by rotating, adjust the air flow direction of the air conditioner expelled from the air outlet respectively. The airflow direction adjustment control unit can independently adjust the rotational states of the various airflow direction adjustment plates respectively. The airflow direction adjustment control unit causes the entire body of at least any of the various airflow direction adjustment plates to be positioned inside the corresponding air outlet to place the air flow adjustment plate. air flow direction in a state of reduced air volume in which the air flow direction adjustment plate reduces the volume of the air conditioner passing through the air outlet or a suppression state in which the air flow adjustment plate Airflow direction suppresses the flow of air conditioning from the air outlet towards the opposite side of the air intake side.

[009] An indoor unit of an air conditioner of a second aspect of the invention is the indoor unit of an air conditioner of the first aspect of the invention and further includes hinge members. The air flow direction adjustment plates are placed away from the rotating axes in the rotation. The hinge members extend from the air flow direction adjustment plates to the rotating axes.
[0010] In this indoor unit of an air conditioning unit, the air flow direction adjustment plates are placed away from the rotating axes, so it is possible to change, rotate, position in the direction of the air conditioning flow at the air outlets.
[0011] An indoor unit of an air conditioner of a third aspect of the invention is the indoor unit of an air conditioner of the first or second aspect of the invention, in which the air flow direction adjustment plates have the surfaces dew condensation suppression which has the dew condensation suppression function as a result of having a groove shape formed in it or being agglomerated. The rear surfaces of the dew condensation suppression surfaces of the airflow direction adjustment plates are smoother than the dew condensation suppression surfaces.
[0012] In this indoor unit of an air conditioning unit, the formation of dew condensation can be suppressed by the dew condensation suppression surfaces of the air flow direction adjustment plates. In addition, the rear surfaces of the dew condensation suppression surfaces are smooth in shape, so by placing these surfaces in a state in which they turn towards the ambient side, the design can be improved. For this reason, it is possible to achieve a balance by simply changing the rotational states of the airflow direction adjustment plates, between suppressing dew condensation on the airflow direction adjustment plates and improving the design when viewed from the side. environment.
[0013] An indoor unit of an air conditioner of a fourth aspect of the invention is the indoor unit of an air conditioner of the third aspect of the invention, where the sides of the dew-suppression surface of the direction adjustment plates of the airflow are concave in shape, and the sides of the rear surfaces of the dew condensation suppression surfaces of the airflow direction adjustment plates are convex in shape.
[0014] In this indoor unit of an air conditioning unit, in the case of an air flow direction adjustment with the air flow direction adjustment plates, the air conditioning that passes through the air outlets can be gently guided in the direction of the path, and in the case of a reduction in the volume of air at the air outlets, it is possible to supply the extent of turbulence in the direction of the air conditioning path.
[0015] An indoor unit of an air conditioner of a fifth aspect of the invention is the indoor unit of an air conditioner of any of the first to fourth aspects of the invention, wherein the indoor unit is equipped with at least four sets of air flow direction adjustment plates and air outlets. The number of sets in which the airflow direction adjustment control unit can simultaneously perform the air volume reduction state is only one set or two sets of the four sets.
[0016] In the indoor unit of an air conditioning unit from the first to the fourth aspect, if the state of reduced air volume ends up being simultaneously performed in three or more sets of the four sets of air outlets and the direction adjustment plates of the airflow, the volume of air that passes through the remaining airflow section and airflow direction adjustment plates ends up greatly increasing.
[0017] In this regard, in the indoor unit of an air conditioning unit of the fifth aspect, the number of sets in which the air volume reduction state can be simultaneously executed is restricted to two sets or less, so it is possible to supply an excessive increase in the volume of air expelled from the section that does not consider the state of reduced air volume. Advantageous effects of the invention
[0018] In the indoor unit of an air conditioning unit of the first aspect of the invention, it is possible to reduce the volume of air expelled from any air outlet from the various air vents while suppressing dew condensation without using a new part.
[0019] In the indoor unit of an air conditioning unit of the second aspect of the invention, it is possible to change, by rotating, the position in the direction of the air conditioning flow in the air vents.
[0020] In the indoor unit of an air conditioning unit of the third aspect of the invention, it is possible to achieve a balance, simply by changing the rotational states of the airflow direction adjustment plates, between the suppression of dew condensation on the adjustment plates the direction of the air flow and improve the design when viewed from the ambient side.
[0021] In the indoor unit of an air conditioning unit of the fourth aspect of the invention, it is possible to selectively execute: moderately and gently guide, in the direction of the route, the air conditioning that passes through the air vents; and reducing the volume of air while suppressing the extent of turbulence in the direction of the air conditioning path.
[0022] In the indoor unit of an air conditioning unit of the fifth aspect of the invention, it is possible to suppress the excessive increase in the volume of air expelled from the section without considering the state of reduced air volume. Brief description of the drawings

[0039] A ceiling mounted air conditioner belonging to a modality of the present invention will be described below with reference to the drawings. 1 Air conditioner 1
[0040] Figure 1 is a schematic diagram of the configuration of an air conditioning unit 1 in which an indoor unit belonging to the modality of the present invention is employed.
[0041] The air conditioning unit 1 is of the type installed as a result of a type of indoor unit being incorporated into a ceiling, has eight air vents, and can independently rotate and control, by adjusting the air flow direction plate , the inclination angles of the airflow direction adjustment plates arranged in four of the eight air outlets. The air conditioning unit 1 is of the split type of the air conditioning unit, mainly it has an external unit 2, an internal unit 4, a liquid refrigerant connection tube 5 and a gas refrigerant connection tube 6 that interconnect the external unit 2 and the indoor unit 4, and a control unit 7, and sets up a vapor compression refrigerant circuit 10. 1-1 External unit 2
[0042] The external unit 2 is installed in external or similar environments and mainly has a compressor 21, a switching valve with four passages 22, an external heat exchanger 23, an expansion valve 24, a liquid blocking valve 25 , a gas shut-off valve 26, and an external fan 27.
[0043] Compressor 21 is a compressor for sucking in low pressure gas refrigerant, compressing low pressure gas refrigerant into high pressure gas refrigerant, and then discarding high pressure gas refrigerant.
[0044] The four-pass switching valve 22 is a valve for switching the direction of the refrigerant flow when switching between heating and cooling. During cooling, the four-pass switching valve 22 can interconnect the discharge side of the compressor 21 and the gas side of the external heat exchanger 23 and still interconnect the gas block valve 26 and the suction side of the compressor 21 (see the solid lines of the four-pass switching valve 22 in figure 1). Also, during heating, the four-pass switching valve 22 can interconnect the discharge side of the compressor 21 and the gas blocking valve 26 and still interconnect the gas side of the external heat exchanger 23 and the suction side of the compressor 21 (see broken lines on the four-pass switching valve 22 in figure 1).
[0045] The external heat exchanger 23 is a heat exchanger that functions as a condenser of the refrigerant during cooling and functions as an evaporator of the refrigerant during heating. The liquid side of the external heat exchanger 23 is connected to the expansion valve 24, and the gas side of the external heat exchanger 23 is connected to the four-pass switching valve 22.
[0046] Expansion valve 24 is a motor-driven expansion valve that, before sending the refrigerant to an internal heat exchanger 42 (described later), can reduce the pressure of the high pressure liquid refrigerant that has been condensed in the exchanger external heat 23 during cooling and which, before sending the refrigerant to the external heat exchanger 23, can reduce the pressure of the high pressure liquid refrigerant that was condensed in the internal heat exchanger 42 during heating.
[0047] The liquid blocking valve 25 and the gas blocking valve 26 are valves arranged in the openings that connect to external devices and tubes (specifically, the liquid refrigerant connection tube 5 and the gas refrigerant connection tube 6). The liquid shut-off valve 25 is connected to the expansion valve 24. The gas shut-off valve 26 is connected to the four-pass switching valve 22.
[0048] The external fan 27 is placed inside the external unit 2 and forms an air flow that sucks in the external air, supplies the external air to the external heat exchanger 23, and then discharges the external air outside the unit. For this reason, the external heat exchanger 23 has the function of using the external air as a cooling source or a heating source to condense and evaporate the refrigerant. 1 -2 Indoor unit 4
[0049] In the present modality, the indoor unit 4 is a type of air conditioning unit mounted on the ceiling indoor unit called the built-in type to the ceiling and has an enclosure of the internal unit 31, an internal fan 41, an internal heat exchanger 42, a drain pan 40, a bell mouth 41c and other components.
[0050] Figure 2 is an external perspective view of the indoor unit 4. Figure 4 is a schematic plan view showing a state where an upper plate 33a of the indoor unit 4 has been removed. Figure 3 is a schematic side cross-sectional view of the indoor unit 4 and corresponds to a cross-sectional view in cross-section indicated by A-O-A in figure 4.
[0051] The housing of the indoor unit 31 includes a housing body 31a, a decorative panel 32, and the air flow direction adjustment parts 70.
[0052] As shown in figure 3 and figure 4, the body of the enclosure 31a is placed to be inserted into an opening formed in a U ceiling of an air-conditioned room. When the housing body 31a is viewed from above, the housing body 31a is a substantially orthogonal box-like body in which the long sides and short sides are alternately formed, and the bottom surface of the housing body 31a is open . The housing body 31a has a substantially octagonal top plate 33a on which the long sides and short sides are alternately continuously formed, a side plate 34 extending downwardly from the peripheral edge part of the upper plate 33a, and a plate bottom 33b that supports the top plate 33a and the side plate 34 from the bottom. Side plate 34 is configured from side plates 34a, 34b, 34c, and 34d, which correspond to the long sides of the upper plate 33a, and from side plates 34e, 34f, 34g, and 34h, which correspond with the short sides of the upper plate. 33 a. A connection tube on the liquid side 5a and a connection tube on the gas side 6a to interconnect the internal heat exchanger 42 and the refrigerant connection tubes 5 and 6 penetrate the side plate 34h. As shown in figure 6, which is a bottom view in a state where the decorative panel 32 and other components are not fixed, a substantially quadrilateral opening is arranged in the center of the lower plate 33b, several openings are arranged around the opening, and the lower plate 33b forms a lower surface of the housing body 31a. As shown in figure 3, the bottom plate 33b is formed to extend outwardly than the top plate 33a and side plate 34, and the decorative panel 32 is attached to the bottom surface side (the ambient side) of the bottom plate 33b .
[0053] As shown in figure 3, figure 4 and figure 6, inside the enclosure 31a an airflow passage inlet 35a is arranged to catch air from an air inlet 35 inside the housing body 31a and outlets airflow passageways 51a, 52a, 53a, 54a, 61a, 62a, 63a, and 64a that are placed to surround the outside of the airflow passageway inlet 35a, have shapes that extend in a substantially vertical direction , and are to expel the air conditioning in the room.
[0054] As shown in figure 2, figure 3 and figure 4, the decorative panel 32 is placed to fit into the opening in the U ceiling. The decorative panel 32 is a plate-shaped body having a substantially quadrilateral shape as seen from above and is mainly fixed to the lower end part of the housing body 31a as a result of being fixed on the ambient side with respect to the lower plate 33b of the housing body 31a. As shown in figure 5, which is a bottom view of the inner unit 4, the decorative panel 32 is configured by a suction grid 32a, a decorative panel of the inner frame 37, and a decorative panel of the outer frame 38, and has an entrance air outlet 35 and an air outlet 36. In an installed state of the indoor unit 4, the lower end of the decorative panel of the inner frame 37 is placed to be positioned slightly lower than the lower end of the decorative panel of the outer frame 38,
[0055] The suction grid 32a is a substantially quadrilateral panel placed in the center of the lower surface of the housing body 31a. As shown in figure 7, which is a bottom view seen from the ambient side, the decorative panel of the inner frame 37 is a member of the substantially quadrilateral frame and is placed between the air inlet 35 and the air outlet 36. An inner margin 37i of the decorative panel of the inner frame 37 is substantially quadrilateral and has a shape whose corner sections are rounded. The outer edge of the decorative panel of the inner frame 37 includes linear portions on the air outlet side of the inner frame 37a, curved parts on the air outlet side of the inner frame 37b, and protruding parts within the opening 37c. The linear portions of the air outlet side of the inner frame 37a are sections that are arranged in the outer positions corresponding to the regions of the centers on the four sides of the inner margin 37i, are substantially parallel to the sides of the inner margin 37i, and extend linearly. The curved parts on the outlet side are positioned more outward as they approach the corners of the decorative panel of the inner frame 37. The curved parts on the air outlet side of the inner frame 37b have concave shapes recessed slightly inward. The protruding parts within the opening 37c configure the outer margins in the vicinity of the corners of the decorative panel of the inner frame 37 and have outwardly protruding shapes whose corners are rounded. The decorative panel of the outer frame 38 is placed to cover the outer margin of the lower surface of the housing body 31a and is placed outside the air outlet 36. As shown in figure 8, which is a bottom view seen from the ambient side, an outer margin 38j of the decorative panel of the outer frame 38 is substantially quadrilateral, has a shape that follows the margin of the lower plate 33b of the housing body 31a, and has rounded corners. The inner edge of the decorative panel of the outer frame 38 includes linear portions on the air outlet side of the outer frame 38d and curved parts on the air outlet side of the outer frame 38e. The linear portions of the air outlet side of the outer frame 38d are sections that are arranged in the inner positions corresponding to the regions of the centers on the four sides of the outer margin 38j, are substantially parallel to the sides of the outer margin 38j, and extend linearly. The curved parts of the air outlet side of the external frame 38e are formed so that their edges are positioned more inward closer to the corners of the decorative panel of the outer frame 38. The curved parts of the air outlet side of the external frame 38e 10 have convex shapes that gently come out. The linear sections of the linear portions on the air outlet side of the outer frame 38d are formed to be shorter than the linear sections of the linear portions on the air outlet side of the inner frame 37a, and the percentage of the curved parts on the side of the outer frame. air outlet of outer frame 38e in length along the inner frame is large, so the bottom view of the linear portions of the air outlet side of outer frame 38d and the curved parts of the air outlet side of outer frame 38e shows that have a shape close to that of a circle.
[0056] The air inlet 35 is a substantially quadrilateral opening disposed in the substantial center of the suction grid 32a. A filter 39 for removing dirt and dust in the air that has been sucked from an air inlet 35 is disposed in an air inlet 35. The airflow passage inlet 35a mentioned above leads to an air inlet 35 inside the body of the housing 31a.
[0057] The air outlet 36 is arranged between the decorative panel of the inner frame 37 and the decorative panel of the external frame 38 to surround the periphery of an air inlet 35 and is configured of the long air outlets 50 and the air outlets short 60. The long air vents 50 are configured from the four air vents - a first long air outlet 51, a second long air outlet 52, a third long air outlet 53, and a fourth long air outlet 54 - which are arranged in positions corresponding to the sides of the substantially quadrilateral shape of an air inlet 35. The long air outlets 50 are formed to have no margin sections facing into the opening. The long air vents 50 are configured so that the difference in length between their length direction and their width direction, which is an orthogonal direction to the length direction, is smaller than in a conventional air outlet 30 (so the length aspect ratio is less than conventionally), so the initial velocity of air flows expelled from the center regions of the long air outlets 50 can be increased. The short air vents 60 are configured from the four air vents - a first short air outlet 61, a second short air outlet 62, a third short air outlet 63, and a fourth short air outlet 64 - which are arranged in positions corresponding to the corner sections of the substantially quadrilateral shape of an air inlet 35. Air outlet 36 is configured so that long air outlets 50 and short air outlets 60 are alternately arranged and placed in a substantially annul. The first flow passage of the long air outlet 51a, the second flow passage of the long air outlet 52a, third flow passage of the long air outlet 53a, and the fourth flow passage of the long air outlet 54a lead respectively to the first long air outlet 51, second long air outlet 52, third long air outlet 53, and fourth long air outlet 54. Also, the first flow passage of the short air outlet 61a, the second passage of the short air outlet flow 62a, the third short air outlet flow 63a, and the fourth short air outlet flow 64a respectively lead to the first short air outlet 61, the second short air outlet 62, the third short air outlet 63, and the fourth short air outlet 64.
[0058] The air flows F51, F52, F53, F54, F61, F62, F63, and F64 that were conditioned inside the indoor unit 4 are expelled, while having their explosion direction adjusted, respectively from the first long air outlet 51 , the second long air outlet 52, the third long air outlet 53, the fourth long air outlet 54, the first short air outlet 61, the second short air outlet 62, the third short air outlet 63, and of the fourth short air outlet 64.
[0059] As shown in figure 10, which is a cross-sectional view as seen in an axial direction, and in figure 9, which is an external perspective view with respect to the surface mainly facing the ambient side, the adjustment parts of the direction of the Airflow 70 has a shape that is long in one direction of rotation. The air flow direction adjustment parts 70 act as air flow direction adjustment plates that adjust the direction of the air conditioning expelled in the air conditioned environment. In the present embodiment, the airflow direction adjustment parts 70 are not placed in the short air outlets 60 of the air outlet 36 and are only placed in the long air outlets 50. The airflow direction adjustment parts 70 includes a first airflow direction adjustment part 71 that adjusts the direction of the air conditioning expelled from the first long air outlet 51, a second airflow direction adjustment part 72 that adjusts the direction of the expelled air conditioning the second long air outlet 52, a third airflow direction adjustment part 73 that adjusts the direction of the air conditioning expelled from the third long air outlet 53, and a fourth airflow direction adjustment part 74 that adjusts the direction of the air conditioner expelled from the fourth long air outlet 54.
[0060] As shown in figure 9, each of the airflow direction adjustment parts 70 has a flap body 80 and an arm 90 that includes a 90x rotary axis.
[0061] The body of the flap 80 is a plate-shaped member formed to extend in a direction substantially parallel to the rotating axis 90x, and a front surface 80x which is a surface on the opposite side of a rear surface 80y which is a surface in the side where the arm 90 is attached has a curved shape projecting outwards. Because the body of the flap 80 is moderately curved in this way, the air conditioner passing through the long air outlet 50 can be gently guided in the direction of travel. The outer edge of the flap body 80 is formed so as not to have a section with an inwardly recessed shape. As shown in figure 10, in a state where the front surface 80x is mainly facing the ambient side (the down side of the blast airflow), the body of the flap 80 is arranged so that the distance between the body of the flap 80 and the rotating axis 90x becomes shorter as the body of the flap 80 is closer to the ambient side and is arranged so that the distance between the body of the flap 80 and the rotating axis 90x is longer as the body of the flap 80 moves away from the ambient side (which goes upstream of the airflow explosion). For this reason, in a case where the airflow direction adjustment part 70 has rotated, the airflow direction adjustment part 70 follows a path that differs between one end and the other end of the flap body 80 As shown in figure 10, a concave-convex shape part 80x is arranged, to be along the length of the flap body 80, on a front surface 80x of the flap body 80 in a section in the outer region final part in a state where an 80x front surface is mainly facing the down side of the blast air flow. The external part is the section where the concave-convex part 80x is arranged, the front surface 80x of the flap body 80 is configured by a substantially smooth flat surface. In addition, an 80ya bonded blade comprising a blade in which a mixture of short fibers with different pile lengths is uniformly bonded to the rear surface 80y of the body of the flap 80. The bonded blade 80ya is a section that the air conditioner from within the casing body 31a strikes when adjusting the airflow blast direction in a state where the front surface 80x of the flap body 80 faces mainly the downward side of the blast airflow. The 80ya agglomerated blade can suppress the formation of dew condensation on the body of the flap 80. As shown in figure 10, the 80ya agglomerated blade is arranged slightly towards the inside in a state where the 80x front surface is mainly turning beside the explosion air flow. The agglomerated blade 80ya is arranged so that it is smaller than a section in which the agglomerated blade 80ya and the concave-convex shaped part 80x overlap in the direction of the plate thickness of the flap body 80.
[0062] Also, as shown in figure 9, which is an external perspective view seen from one side of the front surface 80x, the shape outer edge of the flap body 80 includes a flap within the linear part 80a, the curved parts within the flap 80b, the flap directions of the end part of length 80c, the linear part of the outer part of the flap 80d, and outer curved parts of the flap 80e. The linear part within the flap 80a is positioned within the flap body 80 in a state where the front surface 80x of the flap body 80 faces the ambient side. The linear part within the flap 80a is the margin of a linear section that extends substantially parallel to the direction of the 90x rotary axis. The linear part within the flap 80a is arranged in the region of the center of the flap body 80 in the direction of the rotating axis 90x and occupies the section of approximately 50% of the flap body 80 in the length direction. The curved parts inside the flap 80b are margins that gently connect the flap directions from the end part of the length 80c to both ends of the linear part inside the flap 80a and have gently protruding shapes towards the outside of the body of the flap 80. The curved parts within the flap 80b occupy sections of approximately 25% each of the direction of the end part of the length of the flap body 80. The directions of the end flap of the length 80c are placed in positions towards the linear part of the outside of the flap 80d in the direction of the width orthogonal to the direction of the rotating axis 90x, that is, in a direction orthogonal to the linear part inside the flap 80a and to the linear part of the outside of the flap 80d. In other words, in a case where the body of the flap 80 is viewed from one side of the front surface 80x, the flap directions at the end of the length 80c are arranged so that the direction of the width distance between the flap directions of the the end part of the length 80c and the linear part inside the flap 80a is longer than the direction of the width distance between the directions of the end flap of the length 80c and the linear part of the outside of the flap 80d. The linear part of the outer part of the flap 80d is positioned on the outer part of the flap body 80 in a state where the front surface 80x of the flap body 80 faces the ambient side. The linear part of the outer part of the flap 80d is the margin of a linear section that extends substantially parallel to the direction of the 90x rotary axis. The linear part of the outer part of the flap 80d is also arranged in the region of the center of the body of the flap 80 in the direction of the rotary axis 90x, but it is shorter than the length of the linear part within the flap 80a. The outer curved parts of flap 80e are margins that connect, more abruptly than the curved parts within flap 80b, the flap directions of the end part of length 80c at both ends of the linear part of the outer part of flap 80d and have shapes gently protruding outward.
[0063] As shown in figure 10, the arm 90 extends as far from a section beyond the rotating axis 90x in a direction away from the rear surface 80y of the flap body 80 in the regions of the directions of the end part of the body length flap 80. That is, as shown in figure 10, the length of the arm 90 is formed farther than a distance D from a rear surface 80y of the body of the flap 80 to the pivot axis 90x. The arm 90 extends so that it tends a little more towards the side of the decorative panel of the outer frame 38 than towards the thickness of the flap body plate 80 in a state where most of the front surface 80x of the body of the flap 80 can be seen when the housing body 31a is viewed from the bottom. As shown in figure 9, the axis members 90a that extend to follow the rotary axes 90x are arranged in the regions of the end parts of the arms 90 on the opposite sides of the end parts on the side of the flap body 80. The arm 90 extends from a slightly lower side of the rear surface 80y of the flap body 80 in a state where the front surface 80x of the flap body 80 faces the ambient side and has a width that is approximately 30% of the width, in the center region, flap body 80.
[0064] The placement relationship between the long air outlets 50 and the airflow direction adjustment parts 70 will be described later.
[0065] The internal fan 41 is a centrifugal fan placed inside the housing body 31a. The internal fan 41 forms an air flow that sucks the ambient air through an air inlet 35 in the decorative panel 32 in the housing body 31a and expels the air through an air outlet 36 in the decorative panel 32 to the outside of the body of enclosure 31a. The internal fan 41 has a fan motor 41a which is arranged in the center of the upper plate 33a of the housing body 31 a and an impeller 41 b which is coupled and driven to rotate by the fan motor 41 a. The impeller 41 b is an impeller having turbo blades and can suck air into impeller 41 b from the bottom and expel air towards the peripheral outer side of impeller 41 b as seen from above.
[0066] The internal heat exchanger 42 is a fin and tube heat exchanger that is angled to surround the periphery of the internal fan 41 as seen from above and is placed inside the housing body 31a. More specifically, the internal heat exchanger 42 is a fin and tube heat exchanger called a cross-fin type that has several heat transfer fins placed at a predetermined interval away from each other and several heat transfer tubes arranged in a state where they penetrate these heat transfer fins towards the thickness of the plate. As described above, the liquid side of the internal heat exchanger 42 is connected to the connection pipe of the liquid refrigerant 5 through the connection pipe of the liquid side 5a. The gas side of the internal heat exchanger 42 is connected to the gas refrigerant connection pipe 6 through the gas connection pipe 6a. In addition, the internal heat exchanger 42 functions as a refrigerant evaporator during cooling and as a refrigerant condenser during heating. For this reason, the internal heat exchanger 42 can perform heat exchange with the air that has been expelled from the internal fan 41, cools the air during cooling, and heats the air during heating.
[0067] The drain pan 40 is placed on the underside of the internal heat exchanger 42 and receives drain water produced as a result of moisture in the air condensing on the internal heat exchanger 42. The drain pan 40 is attached to the bottom of the housing body 31a. Outlet holes 40a, an inlet hole 40b, and a drain water receiving channel 40c are formed in the drain pan 40. The outlet holes 40a are formed in various places to be communicated with the air outlet 36 in the panel decorative 32. The inlet hole 40b is formed to be communicated with the air inlet 35 in the decorative panel 32. A drainage receiving channel 40c is formed on the underside of the internal heat exchanger 42.
[0068] The bell mouth 41 c is placed to correspond with the internal part of the inlet hole 40b in the drain pan 40 and guides the sucked air from an air inlet 35 to the impeller 41 b of the internal fan. 1-3 Control unit 7
[0069] As shown in figure 1, the control unit 7 has an external control unit 7a that controls the various configuration devices of the external unit 2, an internal control unit 7b that controls the various configuration devices of the internal unit 4 , and a controller 7c to receive a user's tuning inputs.
[0070] The control unit 7 performs: independent control of the air flow direction which independently 15 adjusts the air flow directions of the air conditioner expelled from the four air outlets - the first long air outlet 51, the second air outlet long air 52, the third long air outlet 53, and the fourth long air outlet 54 - from the air outlet 36 performing the control that allows the first part of the air flow direction adjustment 71, the second part of the air flow adjustment airflow direction 72, the third airflow direction adjustment part 73, and the fourth airflow direction adjustment part 74 are moved independently by each airflow direction adjustment part 70, to change their rotational states; and interlocking control of the airflow direction which interlocked adjusts the previously mentioned airflow direction by performing the control that causes all first airflow direction adjustment part 71, second direction adjustment part air flow 72, third air flow direction adjustment part 73, and fourth air flow direction adjustment part 74 move in an interlocked manner so that their postures have the same rotational state. Here, controller 7c has an input button and other components and receives an instruction from the user to perform independent control of the air flow direction or to perform interlock control of the air flow direction. In addition, the control unit 7 performs independent control of the air flow direction or interlock control of the air flow direction according to the instruction to carry out independent control of the air flow direction or interlock control of the air flow. direction of airflow that controller 7c received.
[0071] In addition, for independent control of the air flow direction and interlock control of the air flow direction, the control unit 7 also performs, with respect to the four air vents - the first long air outlet 51, the second long air outlet 52, the third long air outlet 53, and the fourth long air outlet 54 - from the air outlet 36, the individual air volume suppression control that further reduces the volume of expelled air of a specific long air outlet 51 to 54 individually independently adjusting the rotational state of each of the airflow direction adjustment parts 70 including the first airflow direction adjustment part 71, the second adjustment part the airflow direction 72, the third airflow direction adjustment part 73, and the fourth airflow direction adjustment part 74 to change a posture. Here, controller 7c can, as described above, receive from the user an instruction to perform the individual air volume suppression control and a design of a specific long air outlet 50 of the selected long air outlets 50 have the air volume expelled from the suppressed long air outlet. In addition, in a case where the controller 7c has received an instruction to perform the individual air volume suppression control, the control unit 7 performs the individual air volume suppression control by rotating the air flow direction adjustment part. 70 is placed in the position of the specific long air outlet 50 so that the volume of air expelled from the specific long air outlet 50 is reduced. Here, the number of long air outlets 50 whose air volumes can be suppressed by the individual air volume suppression control there is two or less, and the control unit 7 prohibits the individual air volume suppression control from be carried out at the same time with respect to three or more of the long air vents 50. Specifically, the control unit 7 allows the individual air volume suppression control to be continued with respect to the specific long air vents 50 whose design of the control unit 7 received first and second, and control unit 7 ignores the adjustment of the individual air volume suppression control inputs with respect to the specific long air vents 50 whose design of controller 7c receives thereafter. In a case where the user cancels, from the controller 7c, the individual air volume suppression control with respect to the specific long air outlet 50, the control unit 7 can then perform the individual air volume suppression control with respect to at the long air outlet 50. Basic actions
[0072] Then, the actions of the air conditioning unit 1 during a cooling operation and a heating operation will be described. 2-1 Cooling action
[0073] In the refrigerant circuit 10 during cooling, the switching valve with four passages 22 is in the state indicated by the solid lines in figure 1. Also, the liquid blocking valve 25 and gas blocking valve 26 are placed in an open state, and the degree of opening of the expansion valve 24 is adjusted to reduce the refrigerant pressure.
[0074] In this state of the refrigerant circuit 10, the low pressure gas refrigerant is sucked into compressor 21. In compressor 21, the low pressure gas refrigerant is compressed and becomes high pressure gas refrigerant. The high pressure gas refrigerant is discharged from the compressor 21.0 High pressure gas refrigerant is sent through the four-pass switching valve 22 to the external heat exchanger 23. In the external heat exchanger 23, the high pressure gas refrigerant performs the heat exchange with the external air, condenses, and becomes high-pressure liquid refrigerant. The high pressure liquid refrigerant is sent to the expansion valve 24. In the expansion valve 24, the high pressure liquid refrigerant has its pressure reduced and becomes low pressure refrigerant in a biphasic gas-liquid state. The low-pressure refrigerant in the two-phase gas-liquid state is sent through the liquid stop valve 25, the connection pipe of the liquid refrigerant 5, and the connection pipe on the liquid side 5a to the internal heat exchanger 42. On the exchanger of internal heat 42, the low-pressure refrigerant in the biphasic state of gas-liquid performs the heat exchange with the air expelled from the internal fan 41, evaporates, and becomes low-pressure gas refrigerant. The low pressure gas refrigerant is sent to the compressor 21 through the connection pipe on the gas side 6a, the connection pipe of the gas refrigerant 6, the gas blocking valve 26, and the four-pass switching valve 22. 2-2 Heating action
[0075] Then, in the refrigerant circuit 10 during heating, the switching valve with four passages 22 is in the state indicated by the broken lines in figure 1. Also, the liquid blocking valve 25 and the gas blocking valve 26 they are placed in an open state, and the degree of opening of the expansion valve 24 is adjusted so that the expansion valve 24 reduces the refrigerant pressure.
[0076] In this state of the refrigerant circuit 10, the low pressure gas refrigerant is sucked into compressor 21. In compressor 21, the low pressure gas refrigerant is compressed and becomes high pressure gas refrigerant. The high-pressure gas refrigerant is discharged from the compressor 21. The high-pressure gas refrigerant is sent to the internal heat exchanger 42 via the four-pass switching valve 22, the gas blocking valve 26, the connecting pipe the gas refrigerant 6, and the connection pipe on the gas side 6a. In the internal heat exchanger 42, the high-pressure gas refrigerant performs the heat exchange with the air expelled from the internal fan 41, which condenses, which makes high-pressure liquid refrigerant. The high pressure liquid refrigerant is sent through the connection pipe on the liquid side 5a, the connection pipe on the liquid refrigerant 5, and the liquid stop valve 25 on the expansion valve 24. On the expansion valve 24, the liquid refrigerant high pressure has its pressure reduced and becomes low pressure refrigerant in a biphasic state of gas-liquid. The low pressure refrigerant in the two-phase gas-liquid state is sent to the external heat exchanger 23. In the external heat exchanger 23, the low pressure refrigerant in the two-phase gas-liquid state performs the heat exchange with the external air, evaporates, and becomes low pressure gas refrigerant. The low pressure gas refrigerant is sent through the four-pass switching valve 22 back to compressor 21. 3 Relationship between placement between long air outlets 50 and airflow direction adjustment parts 70
[0077] Here, the placement of the first airflow direction adjustment part 71 in the region of the first long air outlet 51 will be described. The region of the second long air outlet 52, the region of the third long air outlet 53, and the region of the fourth long air outlet 54 are the same as the region of the first long air outlet 51, so its description will be omitted. 3-1 Placement ratio as seen from below
[0078] Figure 11 is a partially enlarged external view, as seen from below, of the region 15 of the first long air outlet 51.
[0079] When the indoor unit 4 is seen from the bottom, the first airflow direction adjustment part 71 and the airflow direction adjustment drive units 95 are placed inside the first airflow outlet. long air 51.
[0080] The air flow direction adjustment drive units 95 are arranged within the length direction ends of the first long air outlet 51 and outside the length direction ends of the first air flow direction adjustment part. air 71. The air flow direction adjustment drive units 95 are connected to the first air flow direction adjustment part 71 through axis members 90a that extend to follow the 90x rotary axes of arms 90 of the first airflow direction adjustment part 71 and apply actuating force to cause the first airflow direction adjustment part 71 to rotate. Specifically, the airflow direction adjustment actuation units 95 and the axis members 90a of the first airflow direction adjustment part 71 configure the meat mechanisms not shown, and the drive control through the meat is carried out as a result of the control unit 7 by sending the air flow direction adjustment drive units 95 with a control signal to cause the air flow direction adjustment drive units 95 to control the state of activation of the first airflow direction adjustment part 71.
[0081] The outer margin of the first long air outlet 51 is configured by the decorative panel of the outer frame 38, the inner margin of the first long air outlet 51 is configured by the decorative panel of the inner frame 37, and the directions of the final part of the length of the first long air outlet 51 are configured by the internal surfaces of the drive units of the air flow direction adjustment 95. The width, in the directions of the end of the length (the internal surfaces of the drive units of the air flow direction adjustment) air flow 95), the first long air outlet 51 is formed to be approximately 60% of the width, in the region of the center of the length direction, of the first long air outlet 51. Specifically, the outer margin of the first air outlet long 51 is configured by the linear part of the air outlet side of the external frame 38d and the curved parts of the air outlet side of the external frame 38e of the decorative panel of the external frame 38. Also, the margin inner of the first long air outlet 51 is configured by the linear part of the air outlet side of the inner frame 37a and the curved parts of the air outlet side of the inner frame 37b of the decorative panel of the inner frame 37. For this reason, the first long air outlet 51 has, when viewed from below, the shape that protrudes a lot inwards while protruding a little outwards. The protrusion of the first long air outlet 51 inward is formed to be larger than the protrusion of the first long air outlet 51 outward.
[0082] The linear part of the air outlet side of the outer frame 38d of the decorative panel of the outer frame 38 is positioned in the center region of the direction of the length of the first long air outlet 51. The curved parts on the side of the air outlet of the outer frame 38 and of the decorative panel of the outer frame 38 are positioned in the regions of the ends of the length direction of the first long air outlet 51 and in the regions of the outside of the drive units of the air flow direction adjustment 95.
[0083] The linear part of the air outlet side of the inner frame 37a of the decorative panel of the inner frame 37 is positioned in the center region of the direction of the length of the first long air outlet 51. The curved parts on the side of the air outlet of the inner frame 37b of the decorative panel of the inner frame 37 are positioned slightly in both directions from the end of the length of the first long air outlet 51 and into the internal parts of the air flow direction adjustment drive units 95 and in the regions between the air flow direction adjustment drive units 95 and the first air flow direction adjustment part 71.
[0084] The horizontal direction width between the linear part of the outer part of the flap 80d and the outer curved parts of the flap 80e that configure the outer margin of the body of the flap 80 of the first part of the airflow direction adjustment 71 and the part linear of the air outlet side of the outer frame 38d and the curved parts of the air outlet side of the outer frame 38e of the decorative panel of the outer frame 38 30 that configure the outer edge of the first long air outlet 51 is placed to be substantially the same width (approximately 2 cm) across the entire length of the first long air outlet 51.
[0085] The horizontal width direction between the linear part within the flap 80a, the curved parts within the flap 80b, and the flap directions of the end part of the length 80c that configure the inner margin of the body of the flap 80 of the first adjustment part of the airflow direction 71 and the linear part of the air outlet side of the inner frame 37a and the curved parts of the air outlet side of the inner frame 37b of the decorative panel of the outer frame 38 that configure the inner margin of the first outlet long air gap 51 is placed to be substantially the same width (approximately 1 cm) across the length of the first long air outlet 51 so that the mutual margins follow one another.
[0086] The width between the inner edge of the flap body 80 of the first airflow direction adjustment part 71 and the inner edge of the first long air outlet 51 is set to be equal to or less than half the width between the outer edge of the flap body 80 of the first airflow direction adjustment part 71 and the outer edge of the first long air outlet 51. 3-2 Relationship of placement in the center region of the airflow direction adjustment parts 70
[0087] Figure 12 is a schematic cross-sectional view, in the cross section BB in figure 11, in the region of the first long air outlet 51. The posture of the air flow direction 15 that adjusts the part 70 shown in figure 12 is a example of a flap 80 body posture in a case where independent control of the air flow direction or interlock control of the air flow direction is being performed.
[0088] As shown in figure 12, the first flow passage of the long air outlet 51a extends towards the upstream flow of the first long air outlet 51. The surface of the side of the inner wall of the first flow passage of the long air outlet 51a in the region of the first long air outlet 51 is configured by the bottom plate 33b of the housing body 31a. In the region of the center of the length direction of the flap body 80, the surface of the side of the inner wall of the first flow passage of the long air outlet 51a has, as shown in figure 12, a curved shape so that the center of its radius of curvature is positioned on the side of the pivot axis 90x, and the side surface of the inner wall of the first flow passage of the long air outlet 51a is formed to be positioned still on the outermost part closest to the first long air outlet 51. In the region of the center of the length direction of the flap body 80, the lateral surface of the outer wall of the first flow passage of the long air outlet 51a has, as shown in figure 12, the curved shape so that the center of its radius of curvature is positioned on the opposite side from the side of the 90x rotating axis so that the distance between the lateral surface of the outer wall and the lateral surface of the inner wall is maintained, and the lateral surface of the wall. external network of the first flow passage of the long air outlet 51a is formed to be positioned on the outer part closest to the first long air outlet 51. The region of the center of the first flow passage of the long air outlet 51a is inclined so that an angle of inclination 011 of the side surface of the inner wall and the side surface of the outer wall in the section of the first long air outlet 51 at the end of the explosion direction is approximately 40 ° with respect to the horizontal direction, so that the expelled air can be guided further out.
[0089] The rotary axis 90x is positioned in the direction of the air flow amount of the first long air outlet 51 positioned at the end of the first flow passage of the long air outlet 51a. In addition, the rotating axis 90x is placed to be closer to the side of the outer wall side of the first airflow passage of the long air outlet 51a than the side of the inner wall side of the first airflow passage of the long air outlet. long air 51a.
[0090] The arm 90 is positioned in a position substantially coincident with, or in an amount of the air flow, the first long air outlet 51 positioned at the end of the first flow passage of the long air outlet 51a even in the rotational state closest to the first long air outlet 51 of the rotational states of the first airflow direction adjustment part 71.
[0091] As shown in figure 12, the length of the width direction, in the center region, of the body of the flap 80 is arranged so that an angle 01 formed by a line that joins the 90x rotary axis and one end of the direction of the flap body width 80 and a line joining the 90x rotary shaft and the other end of the flap body width 80 direction is approximately 135 °.
[0092] When independent control of the air flow direction or interlock control of the air flow direction is being performed, the flap body 80 of the air flow direction adjustment part 70 is balanced by the actuation units adjusting the direction of air flow 95 in the range of approximately + 30 ° and approximately -30 ° taking as reference a state where the angle of inclination of the section, in the center region, of the front surface 80x is approximately 30 ° (corresponding to the figure 12). 3-3 Relation of placement in the regions of the final parts of the air flow direction adjustment parts 70
[0093] Figure 13 is a schematic cross-sectional view, in cross-section C-C in figure 11, in the region of the first long air outlet 51.
[0094] In the direction regions of the end part of the flap body length 80, the side surface of the inner wall of the first flow passage of the long air outlet 51a has, as shown in figure 13, a flat shape formed to be the outer part closest to the first long air outlet 51 is also positioned, so that the shape differs from the curved shape in the center region. Still, in the regions of the directions of the final part of the body length of the flap 80, the lateral surface of the outer wall of the first passage of the flow of the long air outlet 51 a is like the lateral surface of the inner wall and has, as shown in figure 13, a flat shape formed to be positioned yet the outer part closest to the first long air outlet 51, so that the shape differs from the curved shape in the center region. The shapes of the side surface of the inner wall and the side surface of the outer wall of the first flow passage of the long air outlet 51a are formed so that the shape in the center region of the body length direction of the flap 80 and the shape in the regions of the direction of the end part of the body length of the flap 80 gradually change according to the position of the direction of the length of the body of the flap 80. The region of the end part of the first passage of the flow of the long air outlet 51a is inclined by so that an angle of inclination 021 of the side surface of the inner wall and the side surface of the outer wall in the section of the first long air outlet 51 at the end of the explosion direction is approximately 55 ° with respect to the horizontal direction, so that the expelled air can be guided downwards.
[0095] The length of the width direction, in the regions of the final parts, of the body of the flap 80 is arranged so that, as shown in figure 13, an angle 02 formed by a line that joins the 90x rotary axis and one end of the the body width direction of the flap body 80 and a line joining the 90x rotary axis and the other end of the body width direction of the flap 80 is approximately 75 °. In other words, the length of the width direction, in the regions of the end parts, of the flap body 80 is configured to be approximately 40% of the length of the width direction, in the center region, of the flap body 80. 4 Relationship of placement between the long air outlets 50 and the airflow direction adjustment parts 70 during shutdown
[0096] When controller 7c receives an instruction from the user to shut down (a state where the cooling action and the heating action are not carried out), the control unit 7 sends a control signal to the steering adjustment drive units airflow adjustment 95 to make the airflow direction adjustment parts 70 — that is, all of the first airflow direction adjustment part 71, the second airflow direction adjustment part 72 , the third airflow direction adjustment part 73, and the fourth airflow direction adjustment part 74 — rotate, where the airflow direction adjustment parts 70 are adjusted so that the centers of its front surfaces 80x substantially vertically downwards.
[0097] For this reason, during closure, when the indoor unit 4 is viewed from the bottom, the inside of the long air outlets 50 appears more covered by the air flow direction adjustment parts 70, so that the direction of the unit between the decorative panel 32 and the air flow direction adjustment parts 70 can be improved. For this reason, the design of indoor unit 4 during shutdown can be improved, and the user can easily know indoor unit 4 is in a shutdown state. 5 Relation of placement between the long air outlets 50 and the airflow direction adjustment parts 70 during the individual air volume suppression control
[0098] Figure 14 is a conceptual diagram of the air volume suppression control.
[0099] When the controller 7c receives an instruction from the user to suppress the volume of air expelled from the specific long air outlet 50, the control unit 7 sends a control signal to the drive units of the air flow direction adjustment 95 , of the air flow direction adjustment drive units 95, which controls the rotational state of the air flow direction adjustment part 70 arranged in the position corresponding to the specific long air outlet 50 instructed by the user. For this reason, the air flow direction adjustment units 95 that received the control signal cause the air flow direction adjustment part 70 whose rotational state that they control themselves to rotate, so as to adjust the adjusting part of the air flow direction 70 to a posture that restricts the volume of air expelled from the long air outlet 50 specified by the user. For example, as shown in figure 14, in a case where indoor unit 4 is placed close to the surface of wall W in a room and next to a user P1 and a user P2, when controller 7c receives an instruction to suppress the volume of air expelled towards user P2, the control unit 7 performs the individual air volume suppression control to reduce the volume of air flow F53 expelled from the third long air outlet 53 towards the surface of the wall W and to also reducing the volume of air flow F52 expelled from the second long air outlet 52 towards user P2. For this reason, unless the provision of air conditioning towards the surface of the wall W where no user can be reduced, and the volume of air desired by the user P2 can be realized. For example, the instruction given by user P2 may include a case where the user P2 wants to reduce the feeling of a draft or a case where the user P2 feels too cold or too hot due to cooling or heating.
[00100] Figure 15 is a cross-sectional view, corresponding to the cross-section B-B in figure 11, showing an example of the inclined state of the air flow direction adjustment part 70 during the individual air volume suppression control.
[00101] The flap body 80 on which the individual air volume suppression control is carried out is adjusted by the air flow direction adjustment units 95 so that the front surface 80x faces the flow amount air flow first passage of the long air outlet 51a. Specifically, the flap body 80 is adjusted by the air flow direction adjustment drive units 95 so that a tilt angle 03 (an internal angle) of the section, in the center region, of the front surface 80x with respect to a horizontal plane is approximately 110 ° (which corresponds to a figure 15). During the individual air volume suppression control, as for a flap body 80 posture, the flap body 80 is rotated by the air flow direction adjustment drive units 95, but the flap body 80 and the wall surfaces of the first flow passage of the long air outlet 51a have a placement relationship so that they do not come into contact with each other during the rotation action of the flap body 80 from a posture shown in figure 12 where the control regardless of the air flow direction or the interflow control of the air flow direction is being performed in the posture shown in figure 15 where the individual air volume suppression control is being performed. The direction of one end of the width end and the other end of the end of the width direction of the flap body 80 are temporarily positioned in the air flow below the surface 51 s of the first long air outlet 51 shown in figure 15 in one case where the flap body 80 is being swayed by the air flow direction adjustment drive units 95 during independent air flow direction control or air flow direction interlock control.
[00102] For this reason, the volume of air expelled from the long air outlet 50 in which the individual air volume suppression control has been carried out can be removed. The inclination angle during the individual air volume suppression control is finely adjusted in the range of + 5 ° and -5 ° from the angle of approximately 110 °.
[00103] In a state where the individual air volume suppression control was carried out, a gap of approximately 5 mm to 10 mm is guaranteed (in the section indicated by SI in figure 15) between 15 the wall surface of the first passage of the flow of the long air outlet 51a on the decorative panel side of the outer frame 38 and the end part on the upper side of the flap body 80, so that a small explosion of air flows through it.
[00104] Also, in a state where the individual air volume suppression control was carried out, the final part on the lower side of the flap body 80 (the section indicated by S2 in figure 15) is positioned further upstream of the air flow. air in the first flow passage of the long air outlet 51a than in the first long air outlet 51. For this reason, substantially the entire periphery of the flap body 80 can be surrounded by the air conditioner whose temperature has been adjusted inside the indoor unit 4 , and it can be difficult for air in the environment whose temperature has not been adjusted to touch the flap body 80. For this reason, even in a state where the volume of air expelled from the long air outlet 50 has been reduced by the suppression control of the individual air volume, it can become difficult for ambient air whose temperature that has not been adjusted to reach the flap body 80, and the formation of dew condensation on the flap body 80 can be suppressed. 6 Characteristics of the Present Modality (1)
[00105] In the indoor unit 4 of the air conditioning unit 1 of the present modality, the flap body 80 positioned on the long air outlet 50 specified during the individual air volume suppression control can significantly suppress the volume of air expelled from the air outlets. specific long air 50 as a result of the rotational state of the air flow direction adjustment part 70 being adjusted by air flow direction adjustment drive units 95. For this reason, the volume of air expelled in one direction can be suppressed without blocking the specific long air outlet 50 using a separate member of the flap body 80, etc. or changing the direction of the air flow a lot.
[00106] In addition, the control unit 7 automatically initiates the individual air volume suppression control simply as a result of the user drawing and inserting in the controller 7c the specific long air outlet 50 of the various long air outlets 51 to 54 , so the comfort of a specific user can be improved with a single action. (2)
[00107] For example, when blocking the first long air outlet 51 in the individual air volume suppression control, unlike the above modality, as shown in the comparative example of figure 16, when employing a rotational state in the extent that the surface the flap body 80 in the center region of the direction of the front surface length 80x is parallel to the surface 51 s of the first long air outlet 51, it is difficult for the air whose temperature has been adjusted from the inside of the indoor unit 4 to touch the side from the 80x front surface of the flap body 80, and it is easy for the R51 air whose temperature has not been set on the ambient side to flow on the side of the 80x front surface of the flap body 80. On the other hand, it is easy for the air whose temperature has been adjusted from the inside of the indoor unit 4 to touch the side of the rear surface 80y of the flap body 80. For this reason, even if it may appear that the first long air outlet 51 is closed, it is easy for a difference of and temperature rise between the front surface 80x and the rear surface 80y of the flap body 80, and it is easy for dew condensation to form on the front surface of the flap body 80.
[00108] In this regard, in the indoor unit 4 of the air conditioning unit 1 of the present modality, as shown in figure 15, while the drive units for adjusting the air flow direction 95 adjust the posture of the flap body 80 of so that the front surface 80x of the flap body 80 during the individual air volume suppression control faces upwards from the first flow passage of the long air outlet 51a etc., the flap body 80 is adjusted by the actuation of the air flow direction adjustment 95 so that the side surface of the outer wall of the first flow passage of the long air outlet 51a and one end of the flap body 80 have a positional relationship in which they cannot come into contact with each other (see S1 in figure 15). For this reason, the air whose temperature has been adjusted flows on the side of the front surface 80x and on the side of the rear surface 80y of the flap body 80.
[00109] Also, placing the rotational state of the flap body 80 during the individual air volume suppression control in a state with the inclination angle shown in figure 15, the air flow coming from the first long air outlet 51 part can be effectively suppressed, and differences in percentages of air conditioning volumes flowing on the front surface side 80x and on the rear surface side 80y can be more or less suppressed.
[00110] In addition, the rotational state of the flap body 80 during the individual air volume suppression control is adjusted so that, as shown in figure 15, the projection on the front surface side 80x of the flap body 80 turns one rises upward from the first flow passage of the long air outlet 51a and the recessed side of the rear surface 80y of the flap body 80 faces downward from the first flow passage of the long air outlet 51a. For this reason, compared to the posture where, as shown in figure 16, the projection on the front surface side 80x of the flap body 80 faces downward from the first flow passage of the long air outlet 51a and the recessed side of the surface rear 80y of the flap body 80 faces upward from the first flow passage of the long air outlet 51a, it becomes more difficult for a temperature difference between one side of the front surface 80x and one side of the rear surface 80y of the flap body 80 come up. In addition, the extent of turbulence in the direction of the air conditioning path can be suppressed.
[00111] In addition, the airflow direction adjustment drive units 95 adjust the rotational state of the airflow direction adjustment part 70 so that the flap body 80 during the volume suppression control individual air does not have a section positioned in the direction of air flow down the long air outlet 50. For this reason, it is more difficult for air whose temperature has not been adjusted on the ambient side to reach the flap body 80.
[00112] Additionally, the flap body 80 during the individual air volume suppression control has a posture where the air whose temperature has been adjusted more easily strikes one side of the front surface 80x than one side of the rear surface 80y, but for cause of the agglomerated blade 80ya which suppresses the formation of a dew condensation is arranged on one side of the back surface 80y of the flap body 80, it is difficult for a dew condensation to form even if the ambient air whose temperature has not been adjusted has flowed roughly on one side of the back surface 80y of the flap body 80.
[00113] For this reason, the air whose temperature has been adjusted can flow along the front surface 80x, but also a rear surface 80y in relation to the body of the flap 80 when carrying out the individual air volume suppression control. For this reason, the temperature difference between the front surface 80x and the rear surface 80y of the flap body 80 can be kept small, and the formation of dew condensation can be more effectively suppressed. Particularly in a state where the air conditioner 1 is performing the cooling action, the formation of dew condensation on the body of the flap 80 can be suppressed. (3)
[00114] In the indoor unit 4 of the air conditioning unit 1 of the present modality, as described above, a structure by which the position of the flap body 80 in the direction of the air flow 5 in the first passage of the flow of the long air outlet 51 a is caused to move to be down during the independent control of the air flow direction or the interlock control of the air flow direction and upwards during the individual air volume suppression control is performed as a result of the arms 90 interconnecting the 90x rotary axes and the flap body 80 placed in a position away from the 90x rotary axes.
[00115] In this way, employing a structure where the body of the flap 80 is placed away from the rotary axes 90x and where the rotary axes 90x and the body of the flap 80 are interconnected by the arms 90, the body of the flap 80 can be easily moved to desired position during each control simply by rotation. (4)
[00116] In the indoor unit 4 of the air conditioning unit 1 of the present modality, at the long air outlet 50 in which the individual air volume suppression control is being carried out, the air tends to flow along the surface of the ceiling U , because the speed of the air passing falls.
[00117] In this regard, in the indoor unit 4 of the air conditioning unit 1 of the present mode, as shown in figure 15, while the posture of the flap body 80 is adjusted so that the front surface 80x of the flap body 80 during the individual air volume suppression control faces upwards from the first flow passage of the long air outlet 51a etc., the distance between the side surface of the outer wall of the first flow passage of the long air outlet 51a and the body of the flap 80 becomes narrower (see S1 in figure 15). Consequently, the volume of air 25 leaving the long air outlet 50 in which the individual air volume suppression control is being carried out and remaining in the roof region U can be reduced so that dirt from the roof can be removed. (5)
[00118] In the indoor unit 4 of the air conditioner 1 of the present modality, the flap body 80 during the individual air volume suppression control is in a state where the side of the rear surface 80y on which the agglomerated blade 80ya is arranged it faces the ambient side, and the side of the 80x front surface that has a smooth shape cannot be directed towards the ambient side. However, during the individual air volume suppression control, the flap body 80 is not at the first flow outlet of the long air outlet 51a etc., but is in a slightly deep position to make it difficult for a surface 80y rear of the flap body 80 can be seen, and the positioning is such that it is difficult to see the inside of the indoor unit 4, so the design can be improved. 7 Other modalities (A)
[00119] In the above modality, a case of suppressing the volume of air expelled from the long air outlet 50 specified upon receiving an instruction from the user to perform the suppression control of the individual air volume was taken as an example and described.
[00120] However, the present invention is not limited to this and can also, for example, be configured to perform the control that not only suppresses the volume of air expelled from the specified long air outlet 50 upon receiving an instruction from the user to perform the control of suppression of the individual air volume, but in time it also reduces the volume of air of the internal fan 41 to make it substantially inversely proportional to the number of long air vents 50 in which the control of suppression of the individual air volume is being carried out .
[00121] For this reason, in a case where the volume of air supplied to a specific user has been reduced, the volume of air supplied to the other user can be prevented in an unintentional way and end up increased. (B)
[00122] In the above modality, a case where, in the independent control of the air flow direction, 20 the air flow direction adjustment units 95 cause the air flow direction adjustment parts 70 to rotate was taken as an example and described.
[00123] However, the present invention is not limited to this and can also, for example, be configured to change, in the independent control of the air flow direction, the upper limit and the lower limit of the oscillating angle by each of the parts air flow direction adjustment device 70 whose rotation of the air flow direction drive units 95 controls in a case where, for example, there is an input via the user's controller 7c or in the case of operating mode predetermined.
[00124] For this reason, the airflow direction adjustment drive units 95 do not place the airflow direction adjustment parts 70 in a state in which the airflow direction adjustment parts 70 virtually stop the air expelled from the long air vents 50 as a result of the individual air volume suppression control being carried out, but the air flow direction adjustment drive units 95 can cause the air direction adjustment parts airflow 70 oscillate in the rejection of a section where a user does not like the feeling of a draft being positioned, and it is also possible to maintain the comfort of another user in the area around the user who does not like the feeling of a draft. (Ç)
[00125] In the above modality, a case of significantly suppressing the volume of air expelled from the long air outlet 50 in which an instruction to perform the control of suppression of the individual air volume was received as an example and described.
[00126] However, the present invention is not limited to this; for example, the control unit 7 may, with respect to the posture of the flap body 80 at the long air outlet 50 for which an instruction to perform the individual air volume suppression control has been received, perform the control that intermittently releases, at appropriate time intervals, the posture in which the flap body 80 suppresses the volume of air, such as using the air flow direction adjustment drive units 95 to place the flap body 80 in a posture in which the flap body 80 suppresses the air volume for a predetermined amount of time and thereby causing the flap body 80 to perform a common oscillating operation for another predetermined amount of time. (D)
[00127] In the above modality, a case where the number of long air outlets 50 in which the individual air volume suppression control can be simultaneously performed is determined to be two or less and the control unit 7 performs the control was taken as an example and described.
[00128] However, the present invention is not limited to this; for example, the control unit 7 can also carry out the control so that the number of long air outlets 50 in which the individual air volume suppression control can be carried out simultaneously is only one.
[00129] Also, in a case where there are more than four air outlets in which the flaps that can adjust the direction of the air flow are placed, the present invention can be configured so that it can simultaneously perform the suppression control of the individual air volume in up to 50% of these or can be configured in a way that can simultaneously control the suppression of the individual air volume by up to 25% individually. (AND)
[00130] In the above modality, the indoor unit 4 that expels air conditioning in eight directions was taken as an example and described.
[00131] However, the present invention is not limited to this and can also have a configuration where, for example, in the above mode, the short air vents 60 are not arranged and the directions for expelling are only those of the four air vents long 50. Also, the indoor unit can also be one where there are two air vents. Industrial applicability
[00132] According to the present invention, the volume of air expelled from any air outlet of several air outlets can be reduced while suppressing dew condensation without using a new part, so the present invention is particularly useful in a unit internal air conditioning unit.
