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

(Embodiment 1)
As shown in FIG. 1, the dehumidifying device of the present embodiment includes a substantially box-shaped main body case 1, and the main body case 1 has a substantially rectangular air inlet 2 on the front side surface and a front surface near the front surface. Are provided with a substantially rectangular exhaust port 3 and a substantially cylindrical exhaust port 4 on the back side surface. A heat pump 5 is provided in the main body case 1, and the heat pump 5 is formed by a compressor 6, a radiator 7, an expansion means 8, and a heat absorber 9 sequentially provided downstream of the compressor 6.

  A disc-shaped dehumidifying rotor 10 is rotatably provided between the radiator 7 and the heat absorber 9, and an electric motor 11 is provided as a rotating means for rotating the dehumidifying rotor.

  The dehumidifying rotor 10 includes a moisture releasing portion 12 and a moisture absorbing portion 13. The moisture releasing portion 12 is provided in the air path between the radiator 7 and the heat absorber 9, and the moisture absorbing portion 13 is provided between the heat absorber 9 and the exhaust port 3. It is provided in the air path between.

  Air blowing means 14 is provided in the air path between the moisture absorbing portion 13 of the dehumidifying rotor 10 and the exhaust port 3, and the air sucked into the main body case 1 from the air inlet 2 by the air blowing means 14 is provided by the radiator 7 and the dehumidifying rotor 10. Then, the air is exhausted to the exhaust port 3 through the moisture releasing portion 12, the heat absorber 9, and the moisture absorbing portion 13 of the dehumidifying rotor 10.

  That is, the air sucked into the main body case 1 from the air inlet 2 by the air blowing means 14 is heated by the radiator 7 and becomes high-temperature and low-relative-humidity air, and is blown to the moisture releasing portion 12 of the dehumidifying rotor 10. The air blown to the moisture release unit 12 takes in the moisture of the moisture release unit 12 and is sent to the heat absorber 9 in a high humidity state. The heat absorber 9 is condensed to dehumidify and reaches the moisture absorbing portion 13. Therefore, the moisture releasing part 12 of the dehumidifying rotor 10 in a dry state is rotated by the electric motor 11 that is a rotating means to become a moisture absorbing part 13 that absorbs the humidity that has not been dehumidified by the heat absorber 9 and dehumidifies. The dehumidified air is blown from the exhaust port 3 into the room.

  The present embodiment is characterized by dehumidifying the air blowing means 15 for blowing the air sucked into the main body case 1 from the air intake port 2 to the exhaust port 4 via the heat radiator 7 and the moisture releasing portion 12 of the dehumidifying rotor 10 in order. In addition to being provided in the air path between the moisture release portion 12 of the rotor 10 and the exhaust port 4, the exhaust port 4 is provided with communication means 16 communicating with the outdoors.

  That is, in the present embodiment, the air sucked into the main body case 1 from the air inlet 2 is exhausted through the radiator 7, the moisture releasing portion 12 of the dehumidifying rotor 10, the heat absorber 9, and the moisture absorbing portion 13 of the dehumidifying rotor 10 in this order. Blowing means 14 for blowing air to the port 3 and air blowing means 15 for blowing air sucked into the main body case 1 from the air intake port 2 to the exhaust port 4 through the heat radiator 7 and the moisture release portion 12 of the dehumidifying rotor 10 in order. In addition, the exhaust port 4 is provided with communication means 16 that communicates with the outside, so that the indoor moisture absorbed by the moisture absorbing portion 13 of the dehumidifying rotor 10 is transferred to the radiator 7 by the moisture releasing portion 12 of the dehumidifying rotor 10. The indoor air heated by the air is taken in, and can be exhausted to the outside by the blower means 15 through the exhaust port 4 and the communication means 16.

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

  The air blowing means 15 is formed of a scroll-shaped casing portion 17, an electric motor 18 attached to the casing portion 17, and a blade 19 that is rotated by the electric motor 18. The casing part 17 has the suction inlet 17a in the side surface, and is provided with the discharge outlet 17b in the top | upper surface. The suction port 17 a is configured to face the suction port 2, the radiator 7, and the moisture release portion 12 of the dehumidification rotor 10. Specifically, a substantially rectangular air inlet 2 is located on the front side surface of the main body case 1, facing the lower portion of the air inlet 2, the radiator 7, the moisture releasing portion 12 of the dehumidifying rotor 10, and the casing. The inlet 17a of the part 17 is located. In other words, the intake port 2, the radiator 7, the moisture releasing portion 12 of the dehumidifying rotor 10, and the suction port 17a of the casing portion 17 are positioned substantially in a straight line.

  That is, the air sucked into the front side surface of the main body case 1 by the air blowing means 15 from the substantially rectangular intake port 2 is sucked into the casing portion 17 via the heat radiator 7 and the moisture releasing portion 12 of the dehumidifying rotor 10. Since the air flows into the air blowing means 15 through the substantially straight air path leading to the port 17a, the air path from the air inlet 2 to the air blowing means 15 is shortened, and heat dissipation in the main body case 1 is suppressed. Can be exhausted.

  Further, the air blowing means 15 is located on the back side in the main body case 1, and the exhaust air passage 20, which is an air path from the discharge port 17 b of the air blowing means 15 to the exhaust port 4, is located on the back side in the main body case 1. It is set as the structure which carries out. Specifically, the air blowing means 15 is located in the lower part on the back side in the main body case 1, and the discharge port 17 b is provided on the top surface of the air blowing means 15. 4 is located. An exhaust air passage 20 that connects the discharge port 17 b and the exhaust port 4 of the air blowing means 15 is located on the back side in the main body case 1.

  That is, the main body case 1 is normally installed with the back side of the main body case 1 facing the indoor wall portion, and therefore the exhaust air passage 20 that connects the discharge port 17b of the air blowing means 15 and the exhaust port 4 is provided. Since the high-temperature air flows on the back side of the main body case 1 and is located on the back side in the main body case 1, the temperature of the front side of the main body case 1 is lower than that of the back side. The heat radiation to the room can be suppressed.

  Moreover, the moisture release part 12 of the dehumidification rotor 10 is formed from the upstream moisture release part 12a located upstream with respect to the rotation direction of the dehumidification rotor 10, and the downstream moisture release part 12b located downstream. The air blown by the blowing means 14 passes through the downstream moisture releasing section 12b, and the air blown by the blowing means 15 passes through the upstream moisture releasing section 12a.

  Specifically, the dehumidification rotor 10 includes a moisture absorption part 13 and a moisture release part 12, and the moisture release part 12 is further formed of an upstream moisture release part 12a and a downstream moisture release part 12b. The upstream dehumidifying part 12 a is located upstream of the dehumidifying rotor 10 in the rotational direction of the dehumidifying rotor 10, and the downstream dehumidifying part 12 b is in the rotational direction of the dehumidifying rotor 10. The dehumidification rotor 10 is located on the downstream side of the moisture release portion 12. That is, the hygroscopic portion 13 of the dehumidifying rotor 10 absorbs the humidity that has not been dehumidified by the heat absorber 9, and the hygroscopic portion 13 that has absorbed this humidity is first rotated by the electric motor 11 that is a rotating means, and is upstream-side dehumidified. The portion 12a then rotates further, and the upstream moisture releasing portion 12a becomes the downstream moisture releasing portion 12b. The upstream-side moisture release section 12a passes air that is blown by the blowing means 15, and the downstream-side moisture release section 12b passes air that is blown by the blowing means 14.

  That is, the hygroscopic portion 13 of the dehumidifying rotor 10 absorbs the humidity that has not been dehumidified by the heat absorber 9, and the hygroscopic portion 13 that has absorbed this humidity is first rotated by the electric motor 11 that is a rotating means, and is upstream-side dehumidified. Part 12a. Here, the air sucked into the main body case 1 from the air inlet 2 by the air blowing means 15 is heated by the radiator 7 and becomes high-temperature and low-relative-humidity air, and this air is blown to the upstream-side moisture releasing section 12a. Then, the moisture in the upstream moisture releasing section 12a is released and exhausted to the outside. Next, since the dehumidification rotor 10 further rotates and the upstream side moisture releasing part 12a becomes the downstream side moisture releasing part 12b, the air sucked into the main body case 1 from the air inlet 2 by the blowing means 14 is transferred to the radiator 7. The air is heated at a high temperature and has a low relative humidity, and the air is blown to the downstream moisture releasing section 12b, and the moisture that has not been dehumidified by the upstream moisture releasing section 12a is released by the downstream moisture releasing section 12b. And dehumidifying by the heat absorber 9 and the moisture absorbing portion 13 of the dehumidifying rotor 10 and exhausting it indoors. As a result, the amount of moisture adsorbed by the upstream side moisture releasing unit 12a is larger than the amount of moisture adsorbed by the downstream side moisture releasing unit 12b. It becomes larger than the amount of moisture released by the downstream moisture release unit 12b. That is, since the air passing through the upstream moisture releasing section 12a having a large amount of moisture to be released is exhausted to the outside by the blower 15, the room can be dehumidified efficiently.

  In addition, the suction port 17 a that is the air blowing means 15 is configured to face the intake port 2, the radiator 7, and the upstream side moisture release unit 12 a that is the moisture release unit 12 of the dehumidifying rotor 10.

  Specifically, a substantially rectangular air inlet 2 is located on the front side surface of the main body case 1, facing the lower portion of the air inlet 2, and upstream of the heat radiator 7 and the moisture releasing portion 12 of the dehumidifying rotor 10. The side moisture release part 12a and the inlet 17a of the casing part 17 are located. That is, the intake port 2, the radiator 7, the upstream side moisture release portion 12 a of the moisture release portion 12 of the dehumidifying rotor 10, and the suction port 17 a of the casing portion 17 are positioned substantially in a straight line.

  In other words, the air sucked into the front side surface of the main body case 1 by the air blowing means 15 from the substantially quadrangular intake port 2 passes through the heat dissipator 7 and the upstream dehumidifying portion 12 a of the dehumidifying portion 12 of the dehumidifying rotor 10. Since the air flows into the air blowing means 15 through the substantially straight air passage that leads to the air inlet 17a of the casing portion 17, the air passage from the air inlet 2 to the air blowing means 15 is shortened. Can be efficiently exhausted.

  Further, the exhaust port 4 is configured to be located on the back side surface of the main body case 1. That is, the main body case 1 is usually installed with the back side of the main body case 1 facing the indoor wall portion, so that the communication means 16 that communicates the exhaust port 4 with the outside can be shortened. Heat radiation from 16 to the room can be suppressed.

  The communication means 16 is a substantially cylindrical duct portion 16a, and a heat insulating means is provided on the outer periphery of the duct portion 16a. That is, since the heat insulating material 16b which is a heat insulating means is provided on the outer peripheral portion of the duct portion 16a, heat radiation from the duct portion 16a to the room 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 that a communication path 21 is provided for communicating the air sucked into the main body case 1 from the intake port 2 shown in FIG. Specifically, the communication passage 21 is an air passage that bypasses the air blowing means 14 and the dehumidification rotor 10 and is located on one side surface portion in the main body case 1. Thus, by providing the communication passage 21, the air sucked into the main body case 1 from the air inlet 2 by the air blowing means 14 is blown into the room from the air outlet 3 through the two air passages. is there. On the other hand, the air sucked into the main body case 1 from the air inlet 2 is heated by the radiator 7 and becomes high-temperature and low-relative-humidity air and is blown to the moisture-releasing portion 12 of the dehumidifying rotor 10. The air blown to the moisture release unit 12 takes in the moisture of the moisture release unit 12 and is sent to the heat absorber 9 in a high humidity state. The heat absorber 9 is condensed to dehumidify and reaches the moisture absorbing portion 13. The moisture absorption unit 13 absorbs and dehumidifies the humidity that has not been dehumidified by the heat absorber 9, and the dehumidified air is blown into the room from the exhaust port 3. On the other hand, the air sucked into the main body case 1 from the air inlet 2 is sent to the heat absorber 9 through the communication passage 21, dewed and dehumidified by the heat absorber 9, and reaches the moisture absorber 13. The moisture absorption unit 13 absorbs and dehumidifies the humidity that has not been dehumidified by the heat absorber 9, and the dehumidified air is blown into the room from the exhaust port 3.

  That is, by providing the communication passage 21, the air sucked into the main body case 1 from the air inlet 2 by the air blowing means 14 is blown to the heat absorber 9 through the two air passages. Ventilation resistance to the portion 13 is reduced, the amount of air passing through the moisture absorbing portion 13 is increased, and the amount of moisture absorbed by the moisture absorbing portion 13 is increased. Thereby, the moisture release amount in the moisture release part 12 will also increase. As a result, the efficiency of moisture absorption and moisture release in the dehumidification rotor 10 can be improved, and air containing more moisture can be blown out of the room from the exhaust port 4.

  The communication path 21 is provided with an air volume adjusting means 22 for adjusting the air volume passing through the communication path 21, and the air volume adjusting means 22 adjusts the air volume flowing through the communication path 21, and also from the air inlet 2 into the main body case 1. The amount of air flowing to the exhaust port 3 is sequentially adjusted by the air blowing means 14 through the radiator 7, the moisture releasing portion 12 of the dehumidifying rotor 10, the heat absorber 9, and the moisture absorbing portion 13 of the dehumidifying rotor 10. It is. Specifically, the air volume adjusting means 22 is an openable damper 22a that adjusts the air volume according to the opening degree of the damper 22a. When the opening degree of the communication path 21 is increased, the moisture releasing portion 12 of the dehumidifying rotor 10 is adjusted. When the opening degree of the dehumidifying endothermic air passage 23 which is an air passage communicating from the heat sink 9 to the heat absorber 9 is reduced, and when the opening degree of the communication path 21 is reduced, the dehumidification rotor 12 communicates with the heat absorber 9. The opening degree of the moisture-absorbing and heat-absorbing air passage 23 that is an air passage to be increased is increased.

  In this way, the air sucked into the main body case 1 from the air inlet 2 by the air blowing means 14 by the damper 22a, which is the air volume adjusting means 22 provided in the communication passage 21, is discharged to the exhaust port 3 through the two air paths. The air is blown into the room and the air volume of each air passage can be adjusted.

  That is, since the amount of air blown to the radiator 7 and the heat absorber 9 can be adjusted by the blower unit 14, the balance between the heat radiation amount in the radiator 7 and the heat absorption amount in the heat absorber 9 can be improved, and the heat pump 5 Efficiency can be further improved, and the amount of air blown to the moisture release unit 12 and the moisture absorption unit 13 can be adjusted, so that the amount of moisture released by the moisture release unit 12 and the amount of moisture absorbed by the moisture absorption unit 13 can be balanced. It is possible to improve the efficiency of moisture absorption and desorption of the dehumidifying rotor 10.

(Embodiment 3)
Hereinafter, a dehumidifying apparatus according to Embodiment 3 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 2, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

  The difference from the second embodiment is that, as shown in FIG. 3, the main body case 1 is provided with a humidity measuring means 24 and a control means 25, and the control means 25 is based on the humidity measurement value of the humidity measuring means 24. In addition, the air volume is controlled by the air volume adjusting means 22 and the operation and stop of the rotating means for rotating the dehumidifying rotor 10 are controlled. Specifically, the air volume adjusting means 22 is an openable damper 22a that adjusts the air volume by changing the opening of the damper 22a according to the humidity measurement value of the humidity measuring means 24, and opens the communication path 21. As the degree increases, the opening degree of the moisture release endothermic air passage 23 that is an air passage communicating from the moisture release portion 12 of the dehumidification rotor 10 to the heat absorber 9 decreases, and when the degree of opening of the communication path 21 decreases, dehumidification occurs. The opening degree of the moisture release endothermic air passage 23 which is an air passage communicating from the moisture release portion 12 of the rotor 10 to the heat absorber 9 is increased.

  First, when the humidity measurement value of the humidity measuring means 24 is higher than a predetermined humidity value, the opening degree of the damper 22a which is the air volume adjusting means 22 is set so that the opening degree of the communication path 21 is large and While controlling by the control means 25 so that an opening degree becomes small, the electric motor 11 which is a rotation means to rotate the dehumidification rotor 10 is stopped. Further, when the humidity measurement value of the humidity measuring means 24 is lower than the predetermined humidity value, the opening degree of the damper 22a, which is the air volume adjusting means 22, is set so that the opening degree of the communication path 21 is small and the moisture release heat absorbing air passage 23 is opened. While controlling by the control means 25 so that an opening degree becomes large, the electric motor 11 which is a rotation means which rotates the dehumidification rotor 10 is drive | operated. An example of the predetermined humidity value is 60 to 70%.

  That is, when the humidity measurement value of the humidity measuring unit 24 is higher than a predetermined humidity value, the motor 11 that is a rotating unit that rotates the dehumidifying rotor 10 is stopped, so that the dehumidifying efficiency at high humidity is high. Only 5 is dehumidified. Here, the opening degree of the damper 22a, which is the air volume adjusting means 22, is controlled by the control means 25 so that the opening degree of the communication passage 21 is large and the opening degree of the moisture-absorbing and absorbing air passage 23 is small. As a result, the air flowing through the moisture absorbing section 13 and the heat absorber 9 of the dehumidifying rotor 10 increases as the air flowing through the communication passage 21 having a small air passage resistance increases, and the amount of dehumidification at the heat absorber 9 also increases. Moreover, since the air exhausted outdoors by the ventilation means 15 also increases, the amount of exhaust heat can also be increased.

  On the other hand, when the humidity measurement value of the humidity measuring means 24 is lower than a predetermined humidity value, the dehumidification efficiency is high when the humidity is low by operating the electric motor 11 which is a rotating means for rotating the dehumidifying rotor 10. Dehumidification is performed by the rotor 10 and the heat pump 5. Here, the air sucked into the main body case 1 from the air inlet 2 by the air blowing means 14 is heated by the radiator 7 and becomes high-temperature and low-relative-humidity air, and is blown to the moisture releasing portion 12 of the dehumidifying rotor 10. The air blown to the moisture release unit 12 takes in the moisture of the moisture release unit 12 and is sent to the heat absorber 9 in a high humidity state. The heat absorber 9 is condensed to dehumidify and reaches the moisture absorbing portion 13. Therefore, the moisture releasing part 12 of the dehumidifying rotor 10 in a dry state is rotated by the electric motor 11 that is a rotating means to become a moisture absorbing part 13 that absorbs the humidity that has not been dehumidified by the heat absorber 9 and dehumidifies. Therefore, it can dehumidify efficiently. Moreover, since the air exhausted outdoors by the ventilation means 15 reduces, it can suppress that the air with high outdoor humidity enters a room | chamber interior. As a result, high-temperature and high-humidity air can be exhausted outdoors, so that effective exhaust heat countermeasures can be taken.

  As described above, the present invention includes an air inlet, a first exhaust port, a main body case having a second exhaust port, and a heat pump provided in the main body case. The heat pump includes a compressor, A dehumidification rotor is formed by a radiator, an expansion means, and a heat absorber sequentially provided downstream of the compressor, and a dehumidification rotor is rotatably provided in a space between the radiator and the heat absorber in the main body case. The dehumidification rotor is composed of a moisture release portion and a moisture absorption portion, the moisture absorption portion is provided in an air passage between the heat absorber and the exhaust port, and the moisture release portion is Provided in the air path between the radiator and the heat absorber, the air sucked into the main body case from the air inlet, the radiator, the moisture releasing part of the dehumidifying rotor, the heat absorber, the dehumidifying rotor Air is blown to the first exhaust port through the moisture absorption part. First air blowing means and second air for blowing the air sucked into the main body case from the air intake port to the second exhaust port through the heat radiator and the moisture release portion of the dehumidifying rotor in order. Means are provided, and the second exhaust port is provided with communication means communicating with the outdoors, so that an effective measure against exhaust heat can be taken.

  That is, in the present invention, the air sucked into the main body case from the air intake port, the air blowing means for blowing air to the exhaust port through the radiator, the moisture releasing portion of the dehumidifying rotor, the heat absorber, and the moisture absorbing portion of the dehumidifying rotor sequentially, While providing a second air blowing means for blowing the air sucked into the main body case from the air intake port to the second exhaust port through the radiator and the moisture releasing part of the dehumidification rotor in order, Because it has a communication means that communicates with the outdoors, the room moisture absorbed by the moisture absorption part of the dehumidification rotor is taken in by the indoor air heated by the radiator in the moisture release part of the dehumidification rotor, The air can be exhausted outdoors via the second exhaust port and the communication means.

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

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