J alusin 9 is designed to rotate upon rotation of the louver base 9c, which is rotated by means of a motor 10 for the louver, arranged at a side portion of the ﬁ-side blow outlet 8.
Consequently, the exhaust area can be throttled or increased by fixing or pivoting the shutter 9 in a predetermined direction. Consequently, in performing a drying operation for clothes described later, unevenness in moisture content can be dissolved and blow-out cap är can be iron-applied to the laundry or the like when it is dried. Therefore, laundry can be dried early and evenly. 535 '123 In the rear part 3 a rear blow outlet 11 is formed at an upper part, a first intake inlet 12 to the first airway is formed at an upper part and a suction inlet 13 for the second airway is formed at a lower part.
To the first airway suction inlet 9 and the second airway suction inlet 10 is releasably attached a filter frame 14 having a filter for use in air purification.
Inside the housing 7, as illustrated in Figures 5 to 13, an evaporator 15 is arranged at an upper part of the side of the rear part 3 for generating cool air. A condenser for generating hot air is arranged below the evaporator 15.
At the left side under the housing 7 a compressor 17 is arranged and at the center and on the right side under the housing 7 a water drain tank 18 is arranged for collecting moisture which condenses in the evaporator 15. A float 18a is arranged in the water drain plate 18.
Furthermore, a first air blower 19 is arranged between the evaporator 15 and the front panel 2, which causes the air to pass through the evaporator 15 during suction of the air from the first inlet suction inlet 9 and blows out the cool air from a first gear blow outlet 23 through a first airway 22. The first blower 19 consists of a motor 19a and a genuine l9b.
Furthermore, between the condenser 16 and the front panel 2, a second air blower 20 is arranged, which causes the air to pass through the condenser 16 while sucking in air from the intake air inlet 13 for the second airway and blowing out hot air from a second shift blow outlet 25 through a second airway 24. the second air blower 20 consists of a motor 20a and a genuine 20b. Above the condenser 16 and in the vicinity of the front side blow outlet 8, a heating device 21 is arranged constructed of a nichrome wire, a shielded heater, PTC heater or the like. The number 40 denotes a power line and the numeral 41 denotes a roller arranged at a bottom part 6.
Furthermore, as illustrated in Figure 11 to Fig. 18, under the front blow outlet 8 and the rear blow outlet 11 in the housing 7, a slide-type damper mechanism 26 is provided, which forms the above-mentioned front blow outlet 8 to be divided into left and right of the first switch outlet and the second gear blow outlet 25, and is capable of selecting that the cool air from the first gear blow outlet 23 be caused to blow out of either the front side blow outlet 8 or the rear blow outlet 11, and that the hot air from the second gear blow outlet Is made to blow out from either the front side blow outlet 8 or the rear side blow outlet 11.
The slide-type damper mechanism 26 is divided into two left and right by a separating element 27a, and is composed of a rectangular door frame 27 which slidably holds doors 28 in a front and rear direction, two motors 29 for use in link driving arranged on the separating element 27a and a link member 30 connecting each of the slots 28 to each of the motors 29 for use in link drive.
Furthermore, the size of each hatch 28 is half of the area obtained by dividing the area of the hatch frame 27 two, one to the left and one to the right, with the separating element 27a, a forward blowing, where the hat is blown out from the frontal blowing outlet 8 and rear blowing, where the air is blown out from the rear blow outlet 11 of the switch by allowing each hatch 28 to slide in a forward and reverse direction. In the hatches 28, the one on the left side is the one which alternates between the forward blowing and the blowing on the back at the first shift blowing outlet 23 and the one on the right side is the one which alternates between the forward blowing and the blowing on the back at the second shift blowing outlet 25.
Since each of the doors 28 slides in the forward and backward direction as described above, the trajectory of the door movement is small. Therefore, less space is required and a space saving is achieved.

The purpose of the hot gas bypass circuit 36 and the solenoid valve 37 being arranged in the refrigerant circuit is to heat the evaporator 15 when the exhaust gas from the compressor 17 is bypassed, and to evaporate the moisture adhering to the evaporator 15 by opening the solenoid valve 22 in the hot gas circuit 22.
Furthermore, a control circuit for the dehumidifier according to the first embodiment is arranged in an upper part 5 as illustrated in Fig. 20. The control circuit is composed of an operating part 31 for performing a mode of operation or the like, a control circuit 12. for receiving a command from the operating part 31, a temperature-humidity sensor 33 for inputting detected signals to the control circuit 32, a timer 34 connected to the control circuit 32, motors 19a and 20a for the first and second blowers 19 and 20 for driving by means of of the control circuit 32, motors 29 for use in the link drive, the motor 10 for the blind and a heater 21.

In the following, the operation of a dehumidifier 1 according to the first embodiment of the present invention will be explained concretely.
In the dehumidifier 1 there are four main drive modes as illustrated in Figure 21.
A first drive mode is a dehumidification air operating mode, where both the cool air and the hot air are blown out from the front side blow outlet 8 in the first gear blow outlet 23 and the second gear blow outlet 23. The second mode of operation is a cool air mode of operation where only the cool air can be blown out from the frontal blow outlet of the first shift blow outlet 23.
The third operating mode is a hot air operating mode where only the hot air can be blown out from the front side blow outlet 8 in the second shift blow outlet 23. The fourth operating mode is a blow closed operating node, where only air is blown out from the rear blow outlet 11 in the first shift blow outlet 23 and the second shift blow outlet 23. shift blow outlet 23.
First mode of operation (dehumidification air mode of operation) The dehumidification air drive is intended for performing a dehumidification operation, a clothes drying operation comprising a drying operation for shoes, carpet, shoe cabinets, wardrobe or the like and a dew formation preventing operation. The dehumidifier air operating node is set by operating the dehumidifier air operation mode switch 31c in the operating part 31.
In the dehumidification air operation, as illustrated in Fig. 5 to Fig. 7, Figure 14 and Fig. 21, a hatch 28 at the left side of the hatch frame 26 of the damper mechanism 26 is pushed back as illustrated in Fig. 21 (a) by driving the link member 30 by rotating the motor 29 for use in link drive, so that the cool air generated by the evaporator 15 is blown out of the frontal blow outlet 8 of the first shift blow outlet 23, so that both the cool air generated by the evaporator 15 and the hot air generated by means of condenser 16 and blown out of the front side blow outlet 8 in the first and second shift blow outlet 23 and 25, respectively.
At the same time, a hatch 28 at the right side of the hatch 26s in the damper mechanism 26 is pushed back as illustrated in Fig. 2 (a) by driving the link member 30 through the rotation of the motor 29 for use in link drive, so that the hot hatch generated by condenser 16 is blown out of the front side blow outlet 8 of the second shift blow outlet 25.
Thus, in the dehumidification operation, the cool air generated by the evaporator 15 is blown out of the front side blow outlet 8 of the first shift blow outlet 23 as indicated by an arrow 31 and the hot air generated by the condenser 16 is also blown out of the front side blow air. in the second gear blowing outlet 25, as indicated by an arrow 32 and joining the cool air and both the cool air and the hot air will be blown out.
As described above, in the dehumidifying air operation, the dry cool air and the hot air are combined so that dry air can be blown out of the front side blow outlet 8 of the first and second shift blow outlets 23 and 25. Therefore, the dehumidifying air operation is assumed to be used in a case where washing must dry. in a room during a rainy day or similar, for example. In this case, the laundry is often hung in a relatively high position in the room.
Consequently, the shutter 9 is set in such a way that the shutter angle is "throttled", so that the dry lu ﬁ is blown out towards a relatively high position by operating the shutter change switch 3 le in the operating part 31. As illustrated in ﬁ gur 5 to ﬁ gur 7, the closed shutter 9 is rotated so that the front side blow outlet 8 is opened in the first and second shift blow outlets 23 and 25, respectively, by a rotation of the motor 10 for the shutter. The dry air is thereby blown out towards the relatively high position. (2) Second operating mode (cool air operating mode) This cool air operation provides a simple air cooling operation (focus cooler) and a dehumidification operation. The cool air operating node is set by operating the changeover switch 3 lb in the control unit 31 for cool air / hot air drive mode switching.
In the case of cool air operation, as illustrated in Figure 8 to Figure 10, Figure 15 and Figure 21, only the cool air generated by the evaporator 15 is blown out of the front side blow outlet 8 of the first shift blow outlet 23 and the hot air which generated by means of condenser 19 is blown out from the rear blow outlet 1 1 in the second shift blow outlet 25.
Thus, in order to blow the cool air generated by the evaporator 15 from the front side blow outlet 8 into the first shift blow outlet 23, the cover 28 on the left side of the cover frame 27 of the damper mechanism 26 is moved backward by driving the drive member 30 by rotating the motor 29 used in the link drive as illustrated in Figure 21 (b).
At the same time, the door 28 at the right side of the door frame 27 of the damper mechanism 26 is advanced as illustrated in Figure 211 (b) by driving the link member 30 by rotating the motor 29 for use in the link drive ring, so that the hot hatch generated by the condenser 16 is blown out. from the rear blow outlet 11 of the second shift blow outlet 25.
Thus, in cool air operation, hot air generated by condenser 16 is blown out of the rear blow outlet 11 into the second shift blow outlet 25 and only cool air generated by the evaporator 15 is to be blown out of the first shift blow outlet 8.
In cool air operation, a case is assumed where the dehumidifier 1 is used in a state in which a user is placed in front of the dehumidifier 1.
Consequently, the shutter 9 is set in such a way that the shutter angle becomes "at", so that the cool air is blown out towards a front side of the dehumidifier 1 by operating the shutter switch 31e in the operating part 31. Thus, in the case of cooling air operation the cool air is effectively blown out towards a person placed at a front of the dehumidifier 1, i.e. the dehumidifier 1 is used as a simple cooling machine. (3) Third mode of operation (hot air mode of operation) The hot air operation is intended to perform a clothes drying operation including a drying operation for shoes, a carpet, a shoe storage cabinet, a wardrobe or the like, a dew formation preventing operation and the dehumidification operation. The hot lu ﬁ operating mode is set by operating the switch 3 lb in the control unit 31 for cool air / hot air drive ﬂ mode change.
In the case of hot air operation, as illustrated in Figure 11 to Figure 13, Figure 16 and Figure 21, only the hot air generated by the condenser 19 is blown out of the front side blow outlet 8 of the second shift blow outlet 25 and the cool air generated by of the evaporator 15 is blown out of the rear blow outlet 11 of the first shift blow outlet 25.
Thus, in order for the hot air generated by the condenser 16 to be blown out of the front side blow outlet 8 of the second shift blow outlet 25, the door 28 at the left side of the door frame 26 of the slat mechanism 26 is moved backward by driving the link member 30 by rotating the motor 29 intended for the link drive ring, as illustrated in Figure 2 1 (c).
At the same time, the door 28 at the left side of the door frame 26 of the throttle body 26 is advanced as illustrated in Fig. 21 (c) by driving the link member 30 by rotating the motor 29 for use in the link drive, so that the cool air generated by the evaporator 15 is blown out of the rear blow outlet of the first shift blow outlet 23.
Thus, in hot air operation, the hot air generated by the condenser 16 is blown out only from the front blow outlet 8 of the second shift blow outlet 25 and the cool air generated by the evaporator 15 is to be blown out of the rear blow outlet 11 of the first shift blow outlet 11. .
In hot air operation, the laundry is often hung in a relatively high position in the room. 10 15 20 25 535 '123 12 Consequently, the shutter 9 is set in such a way that the shutter angle will be "shrunk", so that the dry light is blown out towards a relatively high position by operating the shutter switch 31e in the operating part 31.
As illustrated in Figure 11 to Figure 13, the closed shutter 9 is rotated in such a way that it opens the front side blow outlet 8 in the first and second shift blow outlets 23 and 25, respectively, by rotating the motor 10 used for the shutter. The dry lid is thereby blown out towards the relatively high position.
Thus, the drying operation for clothes is performed by blowing out the hot heat from the front side blow outlet 8 in the first and second shift blow outlets 23 and 25, respectively, towards a relatively high position. Without hindrance, speeding up the drying of clothes can be achieved by raising the temperature in the hot air using the heater 21.
Furthermore, there is a case of hot light operation where the dehumidifier 1 is used in a state in which a user is assumed to be placed in front of the dehumidifier 1.
Consequently, the shutter 9 is set in such a way that the shutter angle becomes "wide", so that the hot light is blown out towards a front side of the dehumidifier 1 by operating the shutter switch 3e in the operating part 31.
Thus, in hot air flow, the hot air can be efficiently blown out towards a human being positioned at the front of the dehumidifier I and further by using the heating apparatus 21, the dehumidifier 1 can be considered as a simple heater. (4) Fourth operating mode (air from the rear - dﬁft mode) Air from the rear operating mode is intended for internal cooling (especially for a heating part) and dries drying (internal drying) of moisture adhering to the evaporator 15 which serves as a heat exchanger when a cooling cycle is to be disconnected.
The blow-off dri-drive node is set automatically after the operation of the dehumidifier 1 has ended, namely at the time of completion of a cooling cycle.
In the case of the back vent, as illustrated in Figure 17 and Figure 21, both the air generated by the first air blower 19 and the air generated by the second air blower 20 are blown out of the rear blow outlet 11. in the first and second shift blow outlets 23 and 25, respectively.
In order for the air generated by the first air blower 19 to be blown out of the rear blow outlet 11 of the first shift blow outlet 23, the door 28 at the left side of the door frame 26 of the damper mechanism 26 is advanced by driving the link member 30 by rotating the motor 29 which used for link drive, as illustrated in Figure 2l (d).
At the same time, the hatch 28 at the right side of the hatches 26 of the damper mechanism 26 is moved forward, as illustrated in Fig. 21 (d) by driving the lane member 30 by rotating the motor 29 used in the link drive, so that the air generated by the second blower 20 is blown out from the rear blow outlet 11 of the second shift blow outlet 25.
Thus, during air from rear operation, lu generated by the first air blower 19 is blown out of the rear blow outlet 11 of the first shift blow outlet 23 and the air generated by the second air blower 20 is also blown out of the rear blow outlet 11 of the second shift blower outlet 25.
In air from rear-end operation, the luugen intake of the first and second airway intake inlets 12 and 13, respectively, is blown by means of the first and second lublowers 19 and 20 at the time of closing the cooling cycle out of the rear blow outlet 11 of the first and second shift blow outlets 23. respectively 25, as it passes through the evaporator 15 and condenser 16. Thus, air from back operation is intended for cooling the condenser 16 or the heater 21 and for drying up moisture adhering to the evaporator 15.
In this case, the electromagnetic valve 22 in the hot gas bypass circuit 22 is opened and the evaporator 15 is heated by passing gas discharged from the compressor 17 to the evaporator 15. Thereby, moisture adhering to the evaporator 15 can be effectively evaporated. (5) Fifth operating mode (clothes drying mode) This operating mode is intended for drying clothes and it is possible to set three different types, "standard", "normal and thin" and "strong", using the clothes drying mode switch 3 ld. 10 535 123 14 a) A case where the operating mode is set to "standard" using the clothes drying mode changeover switch 3 1 d In the case when the operating mode is set to. "standar" changes a ratio of dewaxing air and hot air corresponding to a temperature and humidity condition. An open and a closed state, respectively, for the door 28 in the damper mechanism 26 at the front blow outlet 8 and the rear blow outlet 11 in a case of dehumidification air operation, hot air drive ﬁ and cool air operation are those shown in Table 1.
Table 1 Combination of Front blow outlet (rear blow outlet) operations hot air cool air hot air cool air A O O x x B O x x O C x O O x Furthermore, the temperature-humidity condition and a proportion of dehumidification air A and hot air B are as shown in Table 2.
Table 2 Temperature-moisture condition Moisture content (example) high moisture content (eg 50% low moisture content (eg less or more) than 50% temperature high temperature (eg AB 15 ° C or more) low temperature (eg BB less than 15 ° C 10 15 20 25 535 123 15 Table 2 shows, for example, that in a case with a high temperature of 15 ° C or more, the drying operation is performed by dehumidification air A, if the moisture content is 50% or more, and the drying operation is performed with hot air B if the moisture content is less than 50%, but in a case with a temperature lower than 50 ° C, the drying operation is performed with the hot air B regardless of whether high or low moisture content prevails.
According to Table 1 and Table 2, when drying clothes, there are two operating patterns, which means that the operation starts with dehumidifying air A and when the room temperature or moisture content is lowered so that it reaches, for example, the set temperature and moisture content shown in Table 2. air B and continued until the end of the drying operation, and in the case where the room temperature or moisture content is, for example, a low temperature or low moisture content at the set temperature or lower or the set moisture content or lower than that shown in Table 2, the operation with hot air B is performed to end of the drying operation. In addition, for a drying operation for clothes other than those specified above, there is a dehumidification air drain node which is performed with dehumidification hatch A to the end of the drying operation.
In the case of a season where the room temperature exceeds 30 ° C, even if the possibility of performing the drying operation for the clothes with cool lu ﬂ is small, it is possible to e - treat the clothes while cooling them using the cool air before the end of the drying operation. b) A case where the drive mode is set to "normal and thin" or "strong" using the clothes drying mode changeover switch 3 1 d In the case where the drive mode is set to "normal and thin" or "strong", the ratio of dehumidifying air to hot air changes corresponding to a elapsed time from the start of the operation.
Regarding the drying characteristics of clothes, there are two types with a zone with a constant ratio during the first half and a zone with a decreasing ratio during the last half as indicated by the curve in Figure 23.
It is known that the drying rate within the zone with constant ratio during the first half is largely affected by the amount of wind (wind speed) and the zone with decreasing ratio during the last half is affected by the temperature or the relative humidity.
Furthermore, it is also known that a ratio between the constant ratio zone and the decreasing ratio zone changes with the type, thickness or the like of the garments.
Consequently, the clothes can be dried early by blowing out the dehumidifying hat (cool lu ﬂ + hot air) with the greatest amount of lu ﬁ during the first half and during the last half by blowing only hot air with high temperature.
Regarding the point when switching from the zone with constant ratio is to take place to the zone with decreasing ratio, switch from the zones based on calculation based on the room temperature and the relative humidity or based on operating time.
Furthermore, since heavy clothing has a small zone with a constant ratio, the hot air operation is carried out efficiently from beginning to end.
Table 3 summarizes the above described in relation to elapsed time from the start of the operation corresponding to the type of washing.
Table 3 .for ﬂ without time from start (example) - 45 min 45 min or later type of wash normal and thin AB strong BB Consequently set in a case where the wash is normal and thin and the clothes drying mode switch 31d is set to "normal and thin" the de-aeration operation is performed for 45 minutes from the start of operation and after 45 minutes the de-icing air operation is performed. This effectively dries the laundry.
Furthermore, in a case where the laundry is heavy and the clothes drying mode switch 3 ld is set to "heavy", the laundry is dried efficiently by performing the hot air drain from the beginning to the end of the operation. 10 15 20 25 30 535 123 17 Incidentally, by means of a combination with Table 2, a numerical value of the switching time for the damper operations ("after 45 minutes" in Table 3) is estimated automatically by means of a microcomputer depending on the variation of room temperature and humidity. and the type of laundry.
As a result, an operation with the performance of more optimal damper operation is also possible. (5) Control of the air volume As the pressure loss in the airway increases due to the fact that the airway is bent by the damper mechanism when the air is blown out of the blow outlet 11 at the rear, the amount of lu ﬁ is reduced if the control is performed as it To avoid this increase the engine speed and thereby an amount of air corresponding to that of forward blowing can be ensured. This enables stable operation.
Incidentally, since the degree of pressure loss in the airway is weakened in the following order: a case where dehumidification air is blown out> a case where cool air and hot air are blown out> a case where air is blown out the rear, the engine rotational speed is configured to increase accordingly.
As explained above, in the dehumidifier 1 according to the present embodiment, a first air blower 19 is provided which introduces cool lu ﬁ which has passed through the evaporator 15 to the first liquor path 22 and a second lu blower 20 which introduces the hot lu ﬁ which has passed through condenser 16 to the second lu ﬁ path 24 and the damper mechanism 26 with the ability to choose either to cause the cool air to blow out of the front exhaust outlet 8 for the first airway 22 or to cause the hot air to blow out of the blow outlet 8 on the front side of the second airway 24. Thus air exhaust is controlled in such a way that the cool air can be blown out of the blower outlet 8 from the first air duct 22 at the front or so that the hot air can be blown out of the exhaust outlet 8 of the second air duct 24 at the front, or that dehumidification air, in which the cool lu ﬁ is blown out of the exhaust outlet 8 from the first lu ﬁ path 22 on the front side and the hot air b locked out of the exhaust outlet 8 from the second airway 24 on the front side, can be blown out by means of the damper mechanism 26. By selecting exhaust air corresponding to an ambient condition, the ability to dry laundry can be improved and further the dehumidifier 1 can be used as a simple air conditioning device.
In the above-mentioned first embodiment 1, the door 28 in the damper mechanism 26 for switching between forward-facing exhaust and exhaust from the rear side is in the first gear exhaust outlet 23 for exhausting the cool air and another door 28 for switching between forward blowing and blowing from the rear in the second shift exhaust outlet 25 for blowing out the hot air and designed to be controlled automatically so that they are driven by the motor 29 used in link drive via the link element 30. However, one of the two hatches 28 may be designed to be operated manually.
For example, the dehumidification air and the hot air can be automatically switched by manually adjusting the cover 28 in the second forward exhaust outlet 25 for forward blowing and automatically setting another cover 28 in the first shift blow outlet 23. This results in an efficient drying operation.
Second Embodiment Figure 24 is a perspective view illustrating a construction of the damper mechanism in the dehumidifier according to the second embodiment of the present invention.
The construction of the damper mechanism in the second embodiment differs from that in the first embodiment.
The damper mechanism 26 in the above-mentioned first embodiment is of the wear type. This means that the size of each hatch 28 is half of an area obtained by dividing the area of the hatch frame 26 into two, one left and one right, with the separating element 27. A far-reaching blow where the hat is blown out from the blow outlet 8 on the front side and a blow on the back where the air is blown out from the blow outlet 11 on the back is switched by letting each hatch 28 slide back and forth. In contrast, the damper mechanism in the second embodiment is of the rotation type, as illustrated in Figure 24.
This means that the doors 28 are respectively arranged in a rotatable manner at a boundary between the blow outlet 8 at the front and the blow outlet 11 at the rear in the first and second shift blow outlets 23 and 25, respectively. The damper mechanism is designed in such a way that the blow outlet 11 is closed when the blow outlet 8 on the front is open, and the blow outlet 11 on the back is open when the blow outlet 8 on the front is closed due to the rotational position of the door 28. A drive for each door 28 is configured to be performed by hand or by rotation with a motor (not shown) connected to a rotation support for the door 28. The motor driving the damper mechanism 26 may thus be designed to have a small number of parts for transmission. of a drive through a rotational motion. Although the damper mechanism 26 changes from slide type to rotation type, the functions and benefits thereof are the same as those of the slide type.
