JP 59-150231 A

  In the above conventional example, when a dehumidifying operation is performed indoors with a heat pump, heat is generated from the heat pump as well as the dehumidifying action. Therefore, if the heat generated from the heat pump is simply exhausted to the outdoors, the atmospheric pressure in the room is reduced accordingly, so that outdoor air enters the room through a gap or the like. However, since the outdoor air is hot and humid, if it flows into the room, the indoor humidity is rapidly increased. In particular, when the outdoor is highly humid, such as the rainy season, air with a higher humidity than the indoor air enters the room, the indoor humidity increases, and the dehumidifying capacity decreases.

  Then, this invention aims at improving dehumidification capability in a waste heat countermeasure.

  In order to achieve this object, the present invention includes a main body case having first and second air inlets, first and second air outlets, a heat pump provided in the main body case, a dehumidifying rotor, and the The heat pump is formed by a compressor and a first radiator, a second radiator, an expansion unit, and a heat absorber sequentially provided downstream of the compressor. The dehumidification rotor comprises a moisture release portion and a moisture absorption portion, the moisture release portion is provided in an air path between the second radiator and the first radiator, and the moisture absorption portion is provided with the heat absorber. Provided in the air passage between the first exhaust port and the air sucked into the main body case from the first intake port, the second radiator, the dehumidifying part of the dehumidifying rotor, the first First blower means for blowing air to the first exhaust port sequentially through the radiators; Second air blowing means for blowing air sucked into the main body case from a second air intake port to the second exhaust port via the heat absorber and the moisture absorbing portion of the dehumidifying rotor in order, and The exhaust port is provided with communication means communicating with the outdoors, thereby achieving the initial purpose.

  As described above, the present invention relates to a main body case having first and second intake ports, first and second exhaust ports, a heat pump, a dehumidification rotor, and a dehumidification rotor provided in the main body case. The heat pump is formed by a compressor and a first radiator, a second radiator, an expansion unit, and a heat absorber sequentially provided downstream of the compressor, and the dehumidification rotor Is composed of a moisture release portion and a moisture absorption portion, the moisture release portion is provided in the air path between the second radiator and the first radiator, and the moisture absorption portion is the heat absorber and the first radiator. Provided in the air path between the exhaust port and the air sucked into the main body case from the first intake port, the second radiator, the moisture release portion of the dehumidification rotor, and the first radiator From the first air blowing means for sequentially sending air to the first exhaust port, and from the second air intake port The second air blowing means for blowing the air sucked into the main body case to the second exhaust port through the heat absorber and the hygroscopic portion of the dehumidification rotor sequentially, and the first exhaust port, Since the communication means is provided with communication means, it is possible to prevent the dehumidification ability from being reduced in exhaust heat countermeasures.

  That is, in the present invention, the air sucked into the main body case from the first air intake port is sequentially supplied to the first air exhaust port through the second heat radiator, the dehumidifying part of the dehumidifying rotor, and the first heat radiator. A first air blowing means for blowing air, and a second air blowing means for blowing air sucked into the main body case from the second air inlet to the second air outlet through the heat absorber and the moisture absorbing portion of the dehumidifying rotor in order. Since the second exhaust port is provided with a communication means that communicates with the outside, first, the indoor air heated by the second radiator is absorbed by the moisture absorbing portion of the dehumidifying rotor at the moisture releasing portion of the dehumidifying rotor. Takes moisture in the room. Here, although the humidity is high, the heat is taken away when the indoor moisture is taken in by the moisture releasing portion of the dehumidifying rotor, and the air becomes a temperature lower than the temperature of the second radiator. Next, this air is heated by a first radiator having a temperature higher than that of the second radiator, whereby high-temperature and humid air is obtained. This high-temperature and high-humidity air can be exhausted to the outside by the first blower means through the first exhaust port and the communication means.

  In other words, in the present invention, the absolute humidity of high-temperature and high-humidity air exhausted outdoors can be made higher than the absolute humidity of outdoor air, so even if outdoor air flows into the room due to this exhaust, the humidity is so high. Don't be. For this reason, it is possible to increase the dehumidifying capacity in measures against exhaust heat.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(Embodiment 1)
As shown in FIG. 1, the dehumidifying apparatus of this embodiment has a substantially box-shaped main body case 1, and a substantially square-shaped air inlet 2 and main body case 1 at the upper part of the front side surface of the main body case 1. A substantially rectangular air inlet 3 is provided at the center of the front side surface, a substantially rectangular air outlet 4 is provided on the top surface near the rear surface, and a substantially cylindrical exhaust port 5 is provided on the rear side surface. Provided. The main body case 1 includes a heat pump 6, which is formed by a compressor 7 and a radiator 8, a radiator 9, an expansion means 10, and a heat absorber 11 that are sequentially provided downstream of the compressor 7. is doing.

  A disk-shaped dehumidifying rotor 12 is rotatably provided between the radiator 8 and the radiator 9 and the heat absorber 11, and an electric motor 13 is provided as a rotating means for rotating the dehumidifying rotor 12.

  The dehumidifying rotor 12 includes a moisture releasing portion 14 and a moisture absorbing portion 15. The moisture releasing portion 14 is provided in the air path between the radiator 9 and the radiator 8, and the moisture absorbing portion 15 is provided between the heat absorber 11 and the exhaust port 4. It is provided in the air path between.

  Air blowing means 16 is provided in the air path between the moisture absorbing portion 15 of the dehumidifying rotor 12 and the exhaust port 4, and the air sucked into the main body case 1 from the air inlet 3 by the air blowing means 16 by the heat absorber 11 and the dehumidifying rotor 12. Then, the air is blown to the exhaust port 4 through the moisture absorbing portions 15 sequentially.

  That is, the air sucked into the main body case 1 from the air inlet 3 by the air blowing means 16 is dewed by the heat absorber 11 and dehumidified, and reaches the moisture absorbing portion 15. Therefore, the moisture releasing portion 14 of the dehumidifying rotor 12 that has been dried is rotated by the electric motor 13 that is a rotating means to become a moisture absorbing portion 15 that absorbs the humidity that has not been dehumidified by the heat absorber 11 and dehumidifies. The dehumidified air is blown from the exhaust port 4 into the room.

  The present embodiment is characterized in that the air sucked into the main body case 1 from the air inlet 2 is blown to the exhaust port 5 through the radiator 9, the moisture releasing portion 14 of the dehumidifying rotor 12, and the radiator 8 in this order. 17 is provided in the air path between the radiator 8 and the exhaust port 5, and the exhaust port 5 includes communication means 18 that communicates with the outdoors.

  That is, the indoor air heated by the radiator 9 in the moisture releasing section 14 of the dehumidifying rotor 12 takes in the indoor moisture absorbed by the moisture absorbing section 15 of the dehumidifying rotor 12. Here, although the humidity is high, when moisture is taken in by the moisture releasing portion 14 of the dehumidifying rotor 12, heat is taken away, and the air becomes a temperature lower than the temperature of the radiator 9. Next, this air is heated by the radiator 8 having a temperature higher than that of the radiator 9, so that the air becomes high temperature and humidity. This high-temperature and high-humidity air can be exhausted outdoors by the blowing means 17 through the exhaust port 5 and the communication means 18.

  As a result, high-temperature and high-humidity air can be exhausted outdoors, so that effective exhaust heat countermeasures can be taken.

  In addition, the radiator 9 is provided on the upper part of the heat absorber 11, the radiation fins 9a are arranged in the vertical direction, and the radiator 9, the moisture releasing portion 14 of the dehumidifying rotor 12, and the radiator 8 are opposed to each other. The refrigerant pipe 19 from the compressor 7 to the radiator 8 is connected to the upper part of the radiator 8, and the refrigerant pipe 20 from the radiator 8 to the radiator 9 is connected to the upper part of the radiator 9. Specifically, the disc-shaped dehumidification rotor 12 rotates around a central shaft portion 21 in the horizontal direction, and a substantially semicircular portion located above the central shaft portion 21 becomes a moisture release portion 14. The substantially semicircular portion located below the shaft portion becomes the moisture absorption portion 15. On the wind path upstream side of the moisture absorption unit 15, a heat sink 11 having a substantially horizontally long rectangular shape is provided to face the moisture absorption unit 15. And on the wind path upstream side of the moisture release part 14, the radiator 9 having a substantially horizontally long shape faces the moisture release part 14, and on the wind path lee side of the moisture release part 14 faces the moisture release part 14. Thus, a radiator 8 having a substantially horizontally long rectangular shape is provided. The high-temperature and high-pressure refrigerant from the compressor 7 first flows through the refrigerant pipe 19 to the upper part of the radiator 8 and then flows through the bellows-like refrigerant pipe 9b of the radiator 8 from the upper part to the lower part. Next, the refrigerant pipe 20 flows to the upper part of the radiator 9 and flows through the bellows-like refrigerant pipe 9b of the radiator 9 from the upper part to the lower part.

  That is, in the radiator 9, since the refrigerant flows from the upper part to the lower part, the upper part becomes hotter than the lower part. Here, the peripheral edge portion 12a on the circumferential side of the disc-shaped dehumidifying rotor 12 is first moved from the lower portion to the upper portion of the radiator 9 by rotating by the electric motor 13, and then the radiator. 9 moves while facing from the upper part to the lower part, and then becomes the moisture absorption part 15. That is, since the temperature of the peripheral edge portion 12a of the dehumidifying rotor 12 is gradually increased, it is efficiently heated to a temperature close to the upper portion of the radiator 9, and the amount of released moisture is improved. Further, in both the radiator 8 and the radiator 9, the refrigerant flows from the upper part to the lower part, so that the upper part has a higher temperature than the lower part. Here, since the radiator 9, the moisture release portion 14 of the dehumidifying rotor 12, and the radiator 8 are opposed to each other, the air that has passed through the upper portion of the radiator 9 mainly dissipates heat through the moisture release portion 14. Similarly, the air that flows to the upper part of the radiator 8 and passes through the lower part of the radiator 9 mainly flows to the lower part of the radiator 8 through the moisture releasing portion 14. In other words, the temperature difference between the upper temperature of the radiator 9 and the upper temperature of the radiator 8 is close to the temperature difference between the lower temperature of the radiator 9 and the lower temperature of the radiator 8. Therefore, the heated air that has passed through the upper part of the radiator 9 is deprived of heat when the moisture is taken in by the moisture releasing section 14, and the temperature drops, but it flows to the upper part of the radiator 8 and rises by the upper part of the radiator 8. When the heated air that has passed through the lower part of the radiator 9 takes in moisture in the moisture releasing section 14 and the heat is taken away, the temperature drops, but it flows to the lower part of the radiator 8 and flows through the upper part of the radiator 8 As a result, the heat quantity of the radiator 8 can be efficiently applied.

  The blower means 17 is formed of a scroll-shaped casing 17a, blades 17b provided in the casing, and an electric motor 17c that rotates the blades. In the moisture release part 14, the upstream side in the rotation direction of the dehumidification rotor 12 is configured. Specifically, the air inlet 2, the radiator 9, the moisture releasing portion 14 of the dehumidifying rotor 12, the radiator 8, and the inlet of the casing 17 a of the air blowing means 17 are in a positional relationship facing each other, and the main body case When viewed from the front of 1, the central portion of the suction port of the casing 17 a is located closer to the upper portion in the moisture release portion 14 of the dehumidifying rotor 12.

  That is, the central portion of the suction port of the casing 17a faces a high temperature portion near the upper portion of the moisture releasing portion 14, that is, near the upper portions of the radiator 9 and the radiator 8, so that the amount of air passing through the portion increases. Since more hot air can be exhausted outdoors, it is possible to take effective measures for exhaust heat.

  In addition, the central portion of the suction port of the casing 17 a is configured to be positioned closer to the upstream side in the rotational direction of the dehumidification rotor 12 in the moisture release portion 14 of the dehumidification rotor 12. Specifically, the air inlet 2, the radiator 9, the moisture releasing portion 14 of the dehumidifying rotor 12, the radiator 8, and the inlet of the casing 17 a of the air blowing means 17 are in a positional relationship facing each other, and the main body case 1, the central portion of the suction port of the casing 17 a is located closer to the upstream side in the rotational direction of the dehumidification rotor 12 in the moisture release portion 14 of the dehumidification rotor 12.

  That is, the central portion of the suction port of the casing 17a faces the upstream side in the rotational direction of the dehumidification rotor 12, that is, the portion that contains more moisture in the moisture release portion 14, and therefore passes through that portion. Since the amount of air to be increased increases and more humid air can be exhausted outdoors, it is possible to take effective measures for exhaust heat.

  Further, the heat absorber 11 is configured such that the refrigerant pipe 22 from the radiator 9 toward the expansion means 10 and the refrigerant pipe 23 from the heat absorber 11 toward the compressor 7 are close to each other to form a heat exchange section 24. . Specifically, the heat absorber 11 is located directly below the radiator 9, and directly below the refrigerant tube 22 that is the lowermost refrigerant tube of the radiator 9, the refrigerant tube that is the uppermost refrigerant tube of the heat absorber 11. 23 is located. Thus, the refrigerant pipe 22 and the refrigerant pipe 23 are close to each other to form the heat exchanging portion 24.

  That is, in the heat exchanging unit 24, the low-temperature refrigerant in the refrigerant pipe 23 takes away the heat of the high-temperature refrigerant in the refrigerant pipe 22, so that the temperature of the refrigerant in the refrigerant pipe 19 can be lowered. As a result, the refrigerant whose temperature has been lowered from the refrigerant pipe 22 is supplied to the expansion means 10, so that the refrigerant decompressed and expanded by the expansion means 10 is supplied to the heat absorber 11 with a sufficiently low temperature. As a result, a large amount of room air is condensed, and the dehumidifying ability can be improved.

  Moreover, the refrigerant | coolant pipe | tube 22 and the refrigerant | coolant pipe | tube 23 which are the heat exchange parts 24 are thermally couple | bonded by the radiation fin. Specifically, the radiation fins 9a of the radiator 9 and the radiation fins 9a of the heat absorber 11 are integrated. As described above, the refrigerant pipe 22 and the refrigerant pipe 23 are thermally coupled by the radiation fins to form the heat exchanging portion 24.

  That is, in the heat exchanging unit 24, the low-temperature refrigerant in the refrigerant pipe 23 takes the heat of the high-temperature refrigerant in the refrigerant pipe 22 through the radiation fins, so that the temperature of the refrigerant in the refrigerant pipe 19 can be lowered. it can. Thereby, since the refrigerant in the state where the temperature is further lowered from the refrigerant pipe 22 is supplied to the expansion means 10, the refrigerant decompressed and expanded by the expansion means 10 is supplied to the heat absorber 11 in a sufficiently low state. As a result, a large amount of room air can be condensed to improve the dehumidifying capacity.

  The vertical length of the intake port 3 is longer than the vertical length of the heat absorber 11, and the lower end of the intake port 3 is located below the lower end of the heat absorber 11. Specifically, the air inlet 3 is substantially square and located at the center of the front side surface of the main body case 1, and a substantially horizontally long heat sink 11 is disposed opposite to the air inlet 3. . The upper end of the intake port 3 and the upper end of the heat absorber 11 are substantially at the same position in the vertical direction, and the lower end of the intake port 3 is positioned below the lower end of the heat absorber 11 in the vertical direction.

  That is, since the lower end of the intake port 3 is located below the lower end of the heat absorber 11 in the vertical direction, the air sucked into the main body case 1 from the intake port 3 by the blower 16 passes through the upper part of the heat absorber 11. The air that passes through the lower part of the heat absorber 11 increases from the air that does. That is, in the heat absorber 11, since the air volume which passes the lower part of the heat absorber 11 which is a lower temperature part increases, dehumidification efficiency improves.

  Moreover, as shown in FIG. 4, the communication means 18 which connects the main body case 1 and the outdoors is a flexible hollow pipe 28 provided with a heat insulating portion on the outer periphery. Specifically, the communication means 18 is provided at the exhaust port 5, has a flexible hollow shape, communicates the main body case 1 and the outdoors, and is a cylindrical flexible pipe 28. A heat insulating material 29 which is a heat insulating part is wound around the body. One end of the pipe 28 is connected to the exhaust port 5 and the other end is taken out through a hole provided in the indoor wall, for example, a hole for air conditioning piping. Thus, when the exhaust port 5 of the main body case 1 communicates with the outdoors, the pipe 28 is flexible, so that the piping work can be easily performed, and condensation within the pipe 28 can be suppressed.

(Embodiment 2)
Hereinafter, a dehumidifying apparatus according to Embodiment 2 of the present invention will be described with reference to the drawings. In addition, about the thing which has the structure similar to the structure of Embodiment 1, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

  The difference from the first embodiment is the positional relationship between the radiator 8 and the radiator 9 shown in FIG. Specifically, air blowing means 17 for blowing air sucked into the main body case 1 from the air intake port 2 to the exhaust port 5 through the heat radiator 8, the moisture releasing portion 14 of the dehumidifying rotor 12, and the heat radiator 9 in order. While providing in the air path between the heat radiator 8 and the exhaust port 5, the exhaust port 5 is provided with the communication means 18 connected to the outdoors.

  That is, the indoor air heated by the radiator 8 having a temperature higher than that of the radiator 9 in the moisture releasing section 14 of the dehumidifying rotor 12 takes in the room moisture absorbed by the moisture absorbing section 15 of the dehumidifying rotor 12. Here, although it is high humidity, heat is taken away when the moisture is taken in by the moisture releasing portion 14 of the dehumidifying rotor 12, and the air becomes a temperature lower than the temperature of the radiator 8. Next, this air is heated by the radiator 9 to be high-temperature and high-humidity air. This high-temperature and high-humidity air can be exhausted outdoors by the blowing means 17 through the exhaust port 5 and the communication means 18.

  As a result, high-temperature and high-humidity air can be exhausted outdoors, so that effective exhaust heat countermeasures can be taken.

  Moreover, the radiator 8 is provided in the upper part of the heat absorber 11, and the radiation fins are arranged in the vertical direction. The radiator 8, the moisture releasing portion 14 of the dehumidifying rotor 12, and the radiator 9 are opposed to each other and compressed. The refrigerant pipe 19 from the machine 7 to the radiator 8 is connected to the upper part of the radiator 8, and the refrigerant pipe 20 from the radiator 8 to the radiator 9 is connected to the upper part of the radiator 9.

  Specifically, the disc-shaped dehumidification rotor 12 rotates around a central shaft portion 21 in the horizontal direction, and a substantially semicircular portion located above the central shaft portion 21 becomes a moisture release portion 14. The substantially semicircular portion located below the shaft portion becomes the moisture absorption portion 15. On the wind path upstream side of the moisture absorption unit 15, a heat sink 11 having a substantially horizontally long rectangular shape is provided to face the moisture absorption unit 15. The radiator 8 having a substantially horizontally long rectangular shape is opposed to the moisture release unit 14 on the windward side of the moisture release unit 14, and the moisture release unit 14 is opposed to the windward side of the moisture release unit 14. Thus, a radiator 9 having a substantially horizontally long rectangular shape is provided. The high-temperature and high-pressure refrigerant from the compressor 7 first flows through the refrigerant pipe 19 to the upper part of the radiator 8 and then flows through the bellows-like refrigerant pipe 9b of the radiator 8 from the upper part to the lower part. Next, the refrigerant pipe 20 flows to the upper part of the radiator 9 and flows through the bellows-like refrigerant pipe 9b of the radiator 9 from the upper part to the lower part.

  In other words, in the radiator 8 having a higher temperature than the radiator 9, the refrigerant flows from the upper part to the lower part, so that the upper part has a higher temperature than the lower part. Here, the peripheral edge portion 12a on the circumferential side of the disc-shaped dehumidifying rotor 12 is first moved while facing the upper portion from the lower portion of the radiator 8 by rotating by the electric motor 13, and then the radiator. 8 moves from the upper part to the lower part, and then becomes the moisture absorption part 15. That is, the peripheral portion 12a of the dehumidifying rotor 12 is gradually heated by the radiator 8 having a temperature higher than that of the radiator 9, so that the peripheral portion 12a is heated efficiently and close to the upper portion of the radiator 8 having a higher temperature than the radiator 9. , Moisture release is improved.

  Further, in both the radiator 8 and the radiator 9, the refrigerant flows from the upper part to the lower part, so that the upper part has a higher temperature than the lower part. Here, since the radiator 8, the moisture release portion 14 of the dehumidifying rotor 12, and the radiator 9 are opposed to each other, the air that has passed through the upper portion of the radiator 8 mainly dissipates heat through the moisture release portion 14. Similarly, the air that flows to the upper part of the radiator 9 and passes through the lower part of the radiator 8 flows mainly to the lower part of the radiator 9 through the moisture releasing part 14. In other words, the temperature difference between the upper temperature of the radiator 9 and the upper temperature of the radiator 8 is close to the temperature difference between the lower temperature of the radiator 9 and the lower temperature of the radiator 8. Therefore, the heated air that has passed through the upper part of the radiator 8 is deprived of heat when the moisture is taken in by the moisture release section 14, and the temperature drops, but it flows to the upper part of the radiator 9 and rises by the upper part of the radiator 9. The temperature of the air and the heated air that has passed through the lower part of the radiator 8 is deprived of heat when the moisture is taken in by the moisture releasing section 14, and the temperature drops. As a result, the heat quantity of the radiator 9 can be efficiently applied.

  The blower means 17 is formed of a scroll-shaped casing 17a, blades 17b provided in the casing, and an electric motor 17c that rotates the blades. In the moisture release part 14, it is set as the structure located near upper part. Specifically, the air inlet 2, the radiator 8, the moisture release portion 14 of the dehumidifying rotor 12, the radiator 9, and the suction port of the casing 17 a of the blowing means 17 are in a positional relationship facing each other, and the main body case When viewed from the front of 1, the central portion of the suction port of the casing 17 a is located closer to the upper portion in the moisture release portion 14 of the dehumidifying rotor 12.

  That is, the central portion of the suction port of the casing 17a faces a high temperature portion near the upper portion of the moisture releasing portion 14, that is, near the upper portions of the radiator 9 and the radiator 8, so that the amount of air passing through the portion increases. Since more hot air can be exhausted outdoors, it is possible to take effective measures for exhaust heat.

  In addition, the central portion of the suction port of the casing 17 a is configured to be positioned closer to the upstream side in the rotational direction of the dehumidification rotor 12 in the moisture release portion 14 of the dehumidification rotor 12. Specifically, the air inlet 2, the radiator 8, the moisture release portion 14 of the dehumidifying rotor 12, the radiator 9, and the suction port of the casing 17 a of the blowing means 17 are in a positional relationship facing each other, and the main body case 1, the central portion of the suction port of the casing 17 a is located closer to the upstream side in the rotational direction of the dehumidification rotor 12 in the moisture release portion 14 of the dehumidification rotor 12.

  That is, the central portion of the suction port of the casing 17a faces the upstream side in the rotational direction of the dehumidification rotor 12, that is, the portion that contains more moisture in the moisture release portion 14, and therefore passes through that portion. Since the amount of air to be increased increases and more humid air can be exhausted outdoors, it is possible to take effective measures for exhaust heat.

  Further, the heat absorber 11 has a configuration in which the third refrigerant pipe 20 from the radiator 8 toward the radiator 9 and the refrigerant pipe 23 from the heat absorber 11 toward the compressor 7 are close to each other to form a heat exchanging portion 27. Is. Specifically, the heat absorber 11 is located directly under the radiator 8, and directly below the refrigerant tube 19 that is the lowest refrigerant tube of the radiator 8, the refrigerant tube that is the uppermost refrigerant tube of the heat absorber 11. 23 is located. Thus, the refrigerant pipe 19 and the refrigerant pipe 23 are close to each other to form the heat exchange part 27.

  That is, in the heat exchanging unit 27, the heat of the high-temperature refrigerant in the refrigerant pipe 19 gives heat to the low-temperature refrigerant in the refrigerant pipe 23, so that the temperature of the refrigerant in the refrigerant pipe 23 can be raised. That is, by raising the temperature of the refrigerant flowing into the compressor 7 and gasifying it, it is possible to prevent the liquid refrigerant from flowing into the compressor 7 and causing the compressor 7 to malfunction. As a result, the dehumidifying ability can be improved.

  Further, the third refrigerant pipe 19 and the refrigerant pipe 23 which are the heat exchanging portions 27 are thermally coupled by the radiation fins. Specifically, the radiation fin 9a of the radiator 8 and the radiation fin 9a of the heat absorber 11 are integrated. As described above, the third refrigerant pipe 19 and the refrigerant pipe 23 are thermally coupled by the radiation fins to form the heat exchange part 27.

  That is, in the heat exchanging unit 27, the heat of the high-temperature refrigerant in the refrigerant pipe 19 gives heat to the low-temperature refrigerant in the refrigerant pipe 23 via the radiation fins, so the temperature of the refrigerant in the refrigerant pipe 23 is increased. Can do. That is, by raising the temperature of the refrigerant flowing into the compressor 7 and gasifying it, it is possible to prevent the liquid refrigerant from flowing into the compressor 7 and causing the compressor 7 to malfunction. As a result, the dehumidifying ability can be improved.

  The vertical length of the intake port 3 is longer than the vertical length of the heat absorber 11, and the lower end of the intake port 3 is located below the lower end of the heat absorber 11. Specifically, the air inlet 3 is substantially square and located at the center of the front side surface of the main body case 1, and a substantially horizontally long heat sink 11 is disposed opposite to the air inlet 3. . The upper end of the intake port 3 and the upper end of the heat absorber 11 are substantially at the same position in the vertical direction, and the lower end of the intake port 3 is positioned below the lower end of the heat absorber 11 in the vertical direction.

  That is, since the lower end of the intake port 3 is located below the lower end of the heat absorber 11 in the vertical direction, the air sucked into the main body case 1 from the intake port 3 by the blower 16 passes through the upper part of the heat absorber 11. The air that passes through the lower part of the heat absorber 11 increases from the air that does. That is, in the heat absorber 11, since the air volume which passes the lower part of the heat absorber 11 which is a lower temperature part increases, dehumidification efficiency improves.

  Moreover, as shown in FIG. 4, the communication means 18 which connects the main body case 1 and the outdoors is a flexible hollow pipe 28 provided with a heat insulating portion on the outer periphery. Specifically, the communication means 18 is provided at the exhaust port 5, has a flexible hollow shape, communicates the main body case 1 and the outdoors, and is a cylindrical flexible pipe 28. A heat insulating material 29 which is a heat insulating part is wound around the body. One end of the pipe 28 is connected to the exhaust port 5 and the other end is taken out through a hole provided in the indoor wall, for example, a hole for air conditioning piping. As described above, when the exhaust port 5 of the main body case 1 communicates with the outside, the pipe 28 is flexible, so that the piping work can be easily performed and dew condensation in the pipe 28 can be suppressed.

  As described above, the present invention relates to a main body case having first and second intake ports, first and second exhaust ports, a heat pump, a dehumidification rotor, and a dehumidification rotor provided in the main body case. The heat pump is formed by a compressor and a first radiator, a second radiator, an expansion unit, and a heat absorber sequentially provided downstream of the compressor, and the dehumidification rotor Is composed of a moisture release portion and a moisture absorption portion, the moisture release portion is provided in the air path between the second radiator and the first radiator, and the moisture absorption portion is the heat absorber and the first radiator. Provided in the air path between the exhaust port and the air sucked into the main body case from the first intake port, the second radiator, the moisture release portion of the dehumidification rotor, and the first radiator From the first air blowing means for sequentially sending air to the first exhaust port, and from the second air intake port The second air blowing means for blowing the air sucked into the main body case to the second exhaust port through the heat absorber and the hygroscopic portion of the dehumidification rotor sequentially, and the first exhaust port, Since the communication means is provided with communication means, it is possible to prevent the dehumidification ability from being reduced in exhaust heat countermeasures.

  That is, in the present invention, the air sucked into the main body case from the first air intake port is sequentially supplied to the first air exhaust port through the second heat radiator, the dehumidifying part of the dehumidifying rotor, and the first heat radiator. A first air blowing means for blowing air, and a second air blowing means for blowing air sucked into the main body case from the second air inlet to the second air outlet through the heat absorber and the moisture absorbing portion of the dehumidifying rotor in order. Since the second exhaust port is provided with a communication means that communicates with the outside, first, the indoor air heated by the second radiator is absorbed by the moisture absorbing portion of the dehumidifying rotor at the moisture releasing portion of the dehumidifying rotor. Takes moisture in the room. Here, although the humidity is high, the heat is taken away when the indoor moisture is taken in by the moisture releasing portion of the dehumidifying rotor, and the air becomes a temperature lower than the temperature of the second radiator. Next, this air is heated by a first radiator having a temperature higher than that of the second radiator, whereby high-temperature and humid air is obtained. This high-temperature and high-humidity air can be exhausted to the outside by the first blower means through the first exhaust port and the communication means.

  In other words, in the present invention, the absolute humidity of high-temperature and high-humidity air exhausted outdoors is higher than that of outdoor air, so even if outdoor air flows into the room due to this exhaust, the humidity is so high. Don't be. For this reason, it is possible to increase the dehumidifying capacity in measures against exhaust heat.

  Therefore, it is expected to be used as a dehumidifier for home use and office use.
