    Elevated temperatures by exercising its desorptivity, and it is slowly rotated by a drive motor.
    Therefore, the dehumidification rotor absorbs moisture trapped inside the air as it passes through the dehumidified air passage and allows the passing air to dry. On the other hand, the dehumidification rotor desorbs the absorbed moisture into heated air passing therethrough and allows the passing air to be heavily humidified as it passes the regenerative air flow passage (see, for example, patent document 1).
    Patent Document 1 - Japanese Patent No. 3857809 (pages 4 to 5, Figure 2) Description of the Invention Problems to be Solved by the Invention However, the dehumidifier described in Patent Document 1 has had the following problems, at the crossing part of a substantially cross-shaped support arm.
    (A) Because the support arm is slenderly shaped, its stiffness is small and a defomiation tends to occur. Since the partition wall plate is an pre-sprayed resin product, the support arm has a special tendency to deform when it is injection molded or when it is exposed to heat from a friend unit or the like.
    (B) Due to this, the attachment shaft (threaded hub) is bent by which the dehumidification rotor with its shaft is supported, bent off and the dehumidification rotor comes into contact with adjacent parts when it rotates.
    (C) Furthermore, if the free space between the dehumidification rotor and the partition plate and / or the free space between the dehumidification rotor and the heating unit is made large to avoid such contact, the air leakage through the free spaces increases. This means a short circuit of indoor air, which does not pass through the dehumidification rotor, and the amount (leakage) of heating air that does not pass through the dehumidification rotor increases.
    (D) Consequently, due to the reduction in the amount of dehumidifying air supplied to the regenerative area of the dehumidification rotor, the temperature of the dehumidifying rotor in the regenerative air fate passage is not increased and the release of absorbed moisture (absorbed moisture) is reduced. In the same way, the temperature of the dehumidification rotor in the dehumidified air fl passage is raised so that the dehumidification (moisture absorption) performance is reduced and the dehumidification capacity decreases. As a result, the temperature in the house increases. 10 15 20 25 30 535 325 (E) In addition, the area through which air passes is reduced (equal to the opening ratio) due to the support member.
    The present invention addresses the above problems with the intention of providing a dehumidifier with high dehumidification efficiency and improved energy saving performance by minimizing the leakage of both indoor air and heating air, by reducing the deflection of a dehumidification rotor with a secure support therefor.
    Means for solving the problems A dehumidifier according to the present invention comprises a housing with an air intake opening and an air discharge opening, a stand having an opening part and fixed in the housing, a protection unit which covers a part of the opening part and is attached to the stand, a shaft support member fixed to the dehumidifier unit, a dehumidification rotor which covers the entire surface of the opening part and is freely rotatably installed on the shaft support member, a regenerative air condenser for condensing moisture contained in regenerative air to water, where the regenerative air is heated by the heating unit and has passed through a part of dehumidification rotor, a regenerative air circulating means for forming a regenerative air circulating air fl fate passage, which starts from and returns to the heater unit, passes through a part of the dehumidifying rotor and the regenerative air condenser, a rotor rotating means attached to the rack for rotating dehumidification rotor and a blower for off humidified air forming a dehumidified air passage from the air intake opening to the air discharge opening, passing through a part of the dehumidification rotor.
    Advantages In the dehumidifier according to the present invention, the shaft support means is fixed in the heating unit, which is attached to the stand, and the dehumidification rotor is freely rotatably installed on the shaft support means, so that "deflection" of the dehumidification rotor during rotation can be suppressed to a minimum.
    As a result, the free space between the dehumidification rotor and the stand and the free space between the dehumidification rotor and the heating unit can be made narrower, which makes it possible to suppress air leakage through these free spaces to a minimum. Consequently, the performance of regeneration (equal to desorption; release of moisture loaded in the dehumidifying rotor to the air passing therethrough) in a regenerative air fl passage passage and dehumidifying performance (equal to absorption; absorption of moisture trapped in air passing through the dehumidifying rotor into it) is improved. - flow passage, and therefore dehumidification of indoor air can be performed as needed without increasing the temperature in the house. In addition, since a support arm for supporting the dehumidifying rotor can be removed, the areas of both the dehumidified air flow passage and the regenerative air fl passage can be extended and the resistance to air fl fate passage in both the dehumidified air fl passage can be reduced and the desenative passage.

    Best Mode for Carrying Out the Invention Embodiment 1 Figure 1 to Figure 9 schematically show a dehumidifier according to an embodiment of the present invention; Incidentally, identical elements or equivalents thereof are indicated by the same reference numerals in each of the drawings and repetition of the descriptions thereof are omitted. In Figure 1 and Figure 2, a dehumidifier 100 comprises a housing 10, a frame 20 fixed in the housing 10 and provided with a large opening part 21, a heating unit 30 fixed on the frame 20 for covering a part of the large opening portion 21, a shaft support member 40 attached to the heater unit 30 and a dehumidifying rotor 50 freely rotatably installed on the shaft support member 40 to cover the entire surface of the large opening portion 2 1.
    In addition, the dehumidifier 100 comprises a regenerative air condenser 60 for condensing moisture contained in the regenerative air to water, the regenerative air having been heated by the protection unit 30 and passing through a part of the dehumidification rotor 50, and a circulating means 70 for regenerative air constituting a regenerative air circulation air fl fate passage for returning the air coming from the heater unit 30 and passing it through a part of the dehumidification rotor 50 and the regenerative air condenser 60.
    Further, the dehumidifier 100 includes a rotor rotating means 80, mounted on the frame 20, for rotating the dehumidifying rotor 50, and a blowing means 90 for dehumidified air forming a dehumidified air flow passage from the air intake opening 11 to the air discharge opening 12, which passes through a portion of the dehumidifying rotor 50.
    Housing The housing 10 is provided with a cabinet provided with an air intake opening 11 on its front surface and an air discharge opening 12 on its top surface and a drainage tank 15 arranged between its bottom surface and a drainage bowl 14, which drainage bowl 14 is fixed in the cabinet parallel to the bottom surface. . Furthermore, a wind direction adjustment plate 13 for adjusting the direction of discharged air is installed in the air discharge opening 12 and a control means (not shown, including detecting means for detecting temperature and / or moisture content) is installed in the housing 10.
    The housing 10 is further divided into the indoor air intake side (left side in Figure 1, lower side in Figure 2) and the indoor air outlet side (right side in Figure 1, the upper side in Figure 2) of the dehumidification rotor 50 and the frame 20.
    Frame Figure 3 is a perspective view of the frame 20 seen from its rear; The frame 20 is a plate-like element having a rectangular circumference and has outer peripheral ends 20a formed at its upper and lower end portions of the drawing, the outer peripheral end 20a being curved towards the air intake side. In addition, the circular large opening portion 21 is in the center portion of the frame 20, a circular small opening portion 22 in the vicinity thereof (bottom left of the drawing) and a rectangular small recessed portion 23 also in the vicinity thereof (top to the left of the drawing) educated.
    Along the circumference of the large opening part 21 a large tubular part 2la is formed, which projects towards the air intake side, and an annular ring 21b is formed at the end of the large tubular part 21a. Further, the inner periphery of the annular ring 2lb of the tubular portion is bent backwardly toward the air discharge side to form an annular ring 2 as well as 2lc on the large tubular portion, and the opening portion enclosed by the annular ring 2 axis 2lc on the large tubular passage which forms a indoor air passes (hereinafter referred to as "opening air | 2ld for indoor air flow").
    Similarly, a small tubular portion 22a is formed in the periphery of the small opening portion 22, which projects to both the air discharge side and the air intake side, and the small tubular portion 22a forms part of a circulating air-destiny passage through which regenerative air passes.
    The small recessed portion 23 has a rectangular cup-shaped configuration projecting toward the air intake side, and the rotor rotating member 80 is housed in the space. This part continues to the large opening part 21 and a circumference of the dehumidification rotor 50 enters the small recessed part 23 through the continuation part.
    Incidentally, in the area of substantially a quarter circle of the circumference of the large opening part 21 on its lower right side in the drawing an installation seat 24 is formed for installation of the heater unit 30.
    Heater Unit Figure 4 (a) is a rear view of the dehumidifier showing the heater unit 30, Figure 4 (b) is a cross-sectional view of the dehumidifier showing the heater unit 30, and Figure 5 is a perspective view showing a disassembled condition of the structure of the regenerative air circulation means. 70. In Figures 4 and 5, the heater unit 30 comprises a cup-like heater housing 32 having a shape approximately corresponding to a quarter circle (fan shape), viewed from its rear, and a heater body 31 housed in the heater housing 32. The heater housing 32 has a rear heater housing portion 33 and a heater housing side member 34 forming a cup-like recessed portion and a heater housing member 35 formed at the end of the heater housing side member 34.
    The side portion 34 of the heater housing is constituted by an arcuate side portion 34a having an arcuate cross-section and a pair of planar side portions 34b, 34d, each having a rectilinear (planar) cross-section, and a shield housing portion 365 forming part of a vent opening portion 36. the circulating air fate passage is formed in the flat side portion 34b of the pair.
    The heater housing flange 35 consists of an arcuate flange portion 35a, which is part of an annular ring, a pair of rectangularly shaped end portions 35b, 35d, and a pivot flange portion 35c corresponding to a pivot portion of a spigot, in which the rectangularly shaped end portion 35b and the rectangular end portion 35b 35d cross each other.
    The arcuate flange portion 35a is fixed in the installation seat 24 on the frame 20. In this case, the heater housing 32 has adequate rigidity since it is present as a cup-like element which is provided with the heater housing 35 end 35.
    Shaft support means In the level part 35c of the heater unit 30, the shaft support means 40 is installed, through which the dehumidification rotor 50 is freely rotatable shaft mounted. The shaft support member 40 passes through a rotor center hole 51 of the dehumidification rotor 50 and supports the dehumidification rotor 50 so that it cannot leave therefrom.
    Figure 6 shows examples of the shoulder support member 40.
    In Figure 6 (a), a shoulder screw 41 with a main part 41a, a cylindrical shaft part 41b and a threaded part 41c formed in an end surface of the cylindrical shaft part 41b opposite the main part 41a. The threaded part 41c is screwed into a female thread (not shown) formed in the pivot part 35c, the cylindrical shaft part 41b passing through the center hole S1 of the rotor of the dehumidifying rotor 50, and the main part 41a preventing the dehumidifying rotor 50 from coming off. Incidentally, the shoulder screw 41 may be mounted in the heating unit 30 in such a way that a through hole is formed in the pivot flange part 35c and a nut (not shown) is screwed onto the threaded part 41c which is passed through the through hole. In Figure 6 (b), a ledge holder 42 has a large diameter portion 42a and a small diameter portion 42b. Furthermore, a screw 42c passing through a through hole formed in the pivot end portion 35c is screwed into a female thread (not shown) formed in the small diameter portion 42b.
    In Figure 6 (c), a cylindrically shaped sleeve 43 is mounted on the pivot flange portion 35c using a screw 44. A screw 42c passing through a formed through hole is screwed into a female thread (not shown) formed in the small diameter portion 42b. Dehumidification rotor The dehumidification rotor 50 is a freely ventilable disc and comprises a rotor center element 52, in which the rotor center rim 51 is arranged, an outer peripheral support frame 54 with a driven gear 53 formed on its outer circumference and an outer peripheral retaining frame 55. Further, the outer peripheral edge of the dehumidification rotor 50 is held by clamping it between the outer peripheral support frame 54 and the outer peripheral retaining frame 55.
    The dehumidification rotor 50 is installed on the heater unit 30 by means of the shaft support means 40 and is arranged in the large opening part 21 of the frame 20. Thus, the dehumidification rotor 50 is accommodated in the large tubular part 2la formed in the large opening part 21.
    Since the end face (smooth plane) of the dehumidification rotor 50 on the air intake side is positioned next to the annular ring of the large tubular member 21c, the largest amount of sucked indoor air passes the dehumidification rotor 50 after passing the indoor air flow orifice portion 2 ld. Similarly, since the end face (smooth plane) of the dehumidification rotor 50 on the air discharge side is located next to the heater housing flange 35 on the heater unit 30, the largest amount of regenerative air passes the indoor air debris opening portion 2 ld after passing the dehumidification rotor 50.
    Thus, as described above, since the shoulder support member 40 is installed on the heater unit 30 having adequate rigidity and the heater unit 30 is fixedly fixed to the frame, the deflection of the shoulder support member 40 is suppressed to a minimum. This makes it possible to bring the end face (smooth plane) of the dehumidification rotor 50 on the air intake side close to the annular ring 21c of the large tubular member and in the same way it becomes possible to fix the heater unit 30 to the frame 20 by bringing the heater housing end 35 near the end (smooth plane) of the dehumidification rotor 50 on the air discharge side.
    Therefore, compared to the conventional case that a shaft support member is installed on a cross-shaped support arm, the amount of leakage of indoor air and regenerative air, which does not pass the dehumidification rotor 50, is significantly reduced.
    Incidentally, the dehumidifying rotor 50 is an element in which a dehumidifying material (equal to an adsorbent) such as zeolite or silica gel is arranged in a base body consisting of a honeycomb structure composed of paper or the like, and has a dehumidifying property (equal to absorption property, the property of removing moisture from passing air) at room temperatures and a regenerative property (equal to the desorption property, the property of releasing the absorbed moisture to passing air) at elevated temperatures. It should be noted that the present invention does not in any way limit the dehumidification material and the basic body. 10 15 20 25 30 535 325 Regenerative air condenser The regenerative air condenser 60 is arranged on the air intake side of the housing 10 and is a hollow grid-like element with spaces to allow regenerative air to pass through its inside. Furthermore, a regenerative air inlet port 61 for incoming regenerative air and a regenerative air outlet port 62 for outgoing regenerative air are formed on its air discharge side surface, and a condensate outflow port 63 for outgoing condensate is formed on its bottom surface.
    This means that as indoor air passes through the free spaces between rods in the grid, regenerative air flowing into the grid is cooled by the indoor air and condensate moisture contained therein.
    Thereafter, the condensate passes the condensate spout port 63 and drips onto a drainage bowl, while the sucked-in indoor air passes between the drainage bowl and the grid and is finally collected in a drainage tank 15.
    Incidentally, the regenerative air outflow opening 62 is connected to the air intake side of the small tubular member 22a formed in the frame 20.
    Regenerative air circulation means The regenerative air circulation means 70 comprises a fl 71 for regenerative air for supply (equal to suction) of regenerative air (equal to indoor air), a motor 72 for the regenerative air fan for rotary drive of fl 71 for regenerative air, a housing 73 for approached fan and a regenerative air collecting part 74 arranged opposite the heating unit 30 with the dehumidifying rotor 50 arranged therebetween.
    The regenerative air fan housing 73 includes a housing cover plate portion 73a having a hollow disc-like shape (equal to a cup with a removed portion in its side surface), a housing cover exhaust portion 73b, which is a channel member having a substantially angular U-shaped cross section, channel elements extend from the fan housing disk portion 73a in its tangential direction, and a planar portion 73c of the ölj housing, which forms an enclosure along with the sk disk portion 73a, and the exhaust portion 73b of the är housing is located on the ns ends formed thereon.
    Furthermore, an inflow opening 73d is formed in the tent housing, into which regenerative air flows, in the flat part 73c of the fan housing at its position opposite the motor motor 72 for regenerative air, and the inflow opening 73d in the fan housing is connected to the small opening part 22 which is coupled. to the small tubular portion 22a formed in the frame 20. On the other hand, the tip portion of the balloon portion 73b of the fan housing is connected to the opening portion 36 of the fan housing of the heater unit 30 by being connected to the heater housing side portion 34b. The regenerative air collecting portion 74 has a substantially quartz circular (fan shaped) cup-like configuration which is substantially symmetrical about a plane with the heater housing 32 of the heater unit 30, and includes a collecting portion front 75 forming a cup-like recess portion. side 76, projecting from the circumference of the collecting part front 75 towards its air discharge side, and a collecting part flange 77 formed at the end of the collecting part side 76. Furthermore, the collecting part 74 for regenerative air is fixed in the frame 20 in a condition such that an arcuate part 77a of collecting the end part of the collecting part som end, which is an annular ring part on the collecting part 77, is in contact with the frame 20. for regenerative air in the regenerative air cow ndensom 60.
    As described above, since the housing 73 of the regenerative air fl is connected to the side portion 34b of the heater housing on the heater unit 30 at the tip portion of the del housing exhaust portion 73b, the regenerative air housing 73 and the heater unit 30 can be considered as a one-piece element having substantially their back (equal to when viewed from their front).
    Furthermore, the element is fixed as a piece in the frame 20 over a wide angular range close to 180 °, which wide range is formed by combining the arcuate flange part 35a and a part of the disc part 73a of the marriage cover fixed to the frame 20.
    Since the shaft support member 40 is thus mounted on an element in one piece which is fixedly connected to the frame 20, this means that the sway of the dehumidification rotor 50 is suppressed to a minimum.
    For this reason it becomes possible to allow the end surface (the smooth side) of the dehumidification rotor 50 on the air intake side to lie close to the annular annular flange 2 lc of the large tubular part on the frame 20 and it also becomes possible to fix the heater unit 30 to the frame 20 in a state which allows the heater housing flange 35 to lie close to the end surface (smooth side) of the dehumidification rotor 50 on the air discharge side.
    Similarly, the regenerative air collecting member 74 is also installed in a condition that allows the flange 77 of the collecting member to be located near the end surface of the dehumidification rotor 50 on the air intake side.
    The circulating air solder passage The regenerative air supplied by the regenerative air fan 71 is heated by the heater 31 as it passes the heater unit 30 and flows into the regenerative air collecting portion 74 after passing through the area of the dehumidification rotor 50 opposite the heater unit 30. After passing through the opening part 78 of the collecting part and the inflow opening 61l of the regenerative air flow into the regenerative air condenser 60 and release the moisture contained therein as condensate, and thereafter, after passing through the outflow opening 62 for regenerative air and the small tubular member 22a returns it from the inflow opening 73d of the fan housing to the plate member 73a of the fan housing.
    Consequently, an air flow passage for regenerative circulating air has been constructed even if a small leak occurs somewhere in the passage.
    Rotor rotation means The rotor rotation means 80, which is accommodated in the small countersunk part 23 in the frame 20, comprises a rotary gear 83 which is engaged with the driven gear 53 arranged on the outer circumference of the dehumidification rotor 50 and a drive motor 82 for rotationally driving the drive gear 83. .
    It should be noted that the present invention is not limited to the type of rotor rotating means 80. For example, in Figure 7, the drive gear 83 is provided with a disc (hereinafter referred to as "a drive gear") having an outer diameter larger than its tooth apex circle. on its one end face. The drive gear shaft 84 can suppress the deflection of the dehumidification rotor 50, as it is in contact with the end face of the driven gear 53 arranged on the dehumidification rotor 50.
    Therefore, it becomes possible to further reduce the free space between the dehumidification rotor 50 and the annular annular flange 21c and the like of the large tubular member by using the drive gear 83 provided with the drive gear shaft 84 and thereby leakage of indoor air or the like can be suppressed.
    Incidentally, a pulling surface (equal to a wear surface) 84a is formed in the drive gear shaft 84, where the pulling surface 84a is inclined in a direction where as it approaches the outer circumference it extends away from the end surface of the driven gear 53. Consequently, the contact between the drive gear flange 84 with the end face of the driven gear 53 becomes easy. Alternatively, instead of the traction surface 84a, it is possible to design a traction surface (equal to an end surface) on the driven gear 53.
    As a further alternative, it is also possible to arrange the drive gear flange 84 on each of the two end surfaces of the drive gear and thereby the driven gear 53 is inserted therebetween.
    Rinsing means for dehumidified air The rinsing means 90 for the dehumidified air comprises a duct for dehumidified air (not shown), which forms an air passage from the large opening part 21 in the frame 20 (exactly corresponding to the area of the large opening part 21 excluding the heater unit 30) to the air discharge opening 12, and a dehumidified air fan 91 arranged in the dehumidified air duct.
    Dehumidifying and Regenerative Function Since the dehumidifying rotor 50 rotates as described above, while being located in the fl passage passage for regenerative air (an area sandwiched between the heater unit 30 and the regenerative air collecting portion 74), heated regenerative air passes therethrough and because it is located in the flow passage for dehumidified air (an area outside the above-mentioned intermediate area, indoor air with a relatively low temperature passes through it.
    Consequently, in a portion of the dehumidification rotor 50 located in the dehumidified air passage passage, moisture contained in the indoor air will be absorbed (removed) by the dehumidification rotor 50 and the indoor air will be dried, so that dried air is discharged from the air discharge port 12 into a room. On the other hand, in a part of the dehumidification rotor 50 positioned in the d passage of regenerative air, moisture is released, which is absorbed thereby at the time when it was placed in the d passage for dehumidified air to be discharged to regenerative air and the quantity of water contained in the part is reduced. Furthermore, in a state where the quantity of water included has been reduced, the said part will move to the fate passage for dehumidified air. On the other hand, regenerative air containing a lot of moisture then flows into the regenerative air condenser 60 and the incoming moisture is condensed into dew, so that it returns to the heating unit 30 again in a state containing a small quantity of water.
    Then, condensed water drips onto the drainage bowl 14 and is collected in a freely soluble drainage tank 15. Incidentally, since the drainage tank 15 is provided with a sensor (not shown) which measures the quantity of water contained therein, the dehumidification operation is stopped when the sensor detects full water. level is reached, and a message about the condition (an indication showing full level or an indication suggesting dewatering) is sent.
    As described above, in accordance with the present invention, the dehumidification rotor 50 is fixedly axially supported on the heater unit 30 formed in a cup-like shape with fl axes. Furthermore, the heat exchanger unit 30 has high rigidity, since it is attached directly to the frame 20, at the same time as it is supported by being connected to the cover 73 for blowing regenerative air, which is attached to the frame 20. Therefore, the deflection (sway) in the dehumidification rotor is suppressed. 50 so that it becomes low, which makes it possible for the free space between the dehumidification rotor 50 and the frame 20, the heating unit 30 or the like to be small, and results in it being possible to minimize leakage of indoor air or regenerative air. 10 15 20 25 30 535 325 13 This * results in it becoming possible to provide a dehumidifier with a high dehumidification efficiency with high energy saving performance.
    Incidentally, the above is configured so that the circular large opening portion 21 is formed in the frame 20; thereby, a form of fomining of the element becomes simple and allows the manufacturing cost to be reduced. However, a substantially cross-shaped (spoke) arm may be installed in the large opening portion 21 for purposes other than the purpose of mounting the shoulder support member 40.
    Industrial Applicability A dehumidifier according to the present invention can be used generally in the form of various dehumidifiers for home and industrial use and also in a large number of different devices in which the dehumidifier is installed. Through the use of regenerative air, it can further be used in a number of different variants of humidifiers for home and industrial use and also as a number of different devices, in which the humidifier is installed.
