  Hereinafter, the present embodiment will be described with reference to the accompanying drawings.

(Embodiment 1)
As shown in FIGS. 1 and 2, the dehumidifying device of this embodiment includes a main body case 3 having an intake port 1 and an exhaust port 2, and a heat pump 4 in the main body case. The heat pump 4 is formed by a compressor 5, a radiator 6, an expansion means 7, and a heat absorber 8.

  The air sucked into the main body case 3 from the air inlet 1 is blown to the air outlet 2 through the radiator 6 and the heat absorber 8 by the blower 9. A dehumidifying rotor 11 is provided between the radiator 6 and the heat absorber 8 so as to be rotatable by a rotor case 10.

A partition 12 extends from the peripheral edge 10b of the hole toward the center, and a disc-shaped receiving plate 13 connected at the center is provided. A cylindrical shaft portion 13 a extending in the direction of the dehumidifying rotor 11 is provided at the center of the receiving plate portion 13. The dehumidifying rotor 11 inserted into the shaft portion 13 a is rotatably held, and the heat absorber 8 of the dehumidifying rotor 11. The side frame portion 11a and the partition portion 12 are rotated by the electric motor 14 that is a rotating means while being in contact with each other.

  Moreover, the dehumidification rotor 11 is a disk body. In this disk body, a ventilation body 15 is provided in a circular ring 11b, and the ventilation body 15 is fixed by a circular ring 11b and a frame portion 11a on the heat absorber 8 side. Further, the ventilation body 15 is configured to have a ventilation structure by winding a zigzag band between two bands in a spiral shape from the inner periphery to the outer periphery in the circular ring 11b. .

  The dehumidifying rotor 11 is composed of a moisture releasing portion 16 and a moisture absorbing portion 17. The moisture absorbing portion 17 is provided in the air path between the heat absorber 8 and the exhaust port 2, and the moisture releasing portion 16 is provided with the radiator 6 and the heat absorber 8. It is provided in the air path between. Specifically, a partition portion 12 extending from the rotor case 10 is provided in the air path between the dehumidification rotor 11 and the heat absorber 8, and the air path from the moisture release portion 16 to the heat absorber 8 by the partition portion 12, The air path from the heat absorber 8 to the moisture absorption part 17 is partitioned. Further, a heater 18 serving as a heating means is provided between the radiator 6 and the moisture release unit 16.

  The dehumidifying operation in the above configuration will be described. The air sucked into the main body case 3 from the air inlet 1 by the air blowing means 19 is heated by the radiator 6 and then further heated by the heater 18 to become air having a high temperature and a low relative humidity, and the moisture releasing portion 16 of the dehumidifying rotor 11. It is blown to.

  The air blown to the moisture releasing unit 16 takes in the moisture of the moisture releasing unit 16 and is sent to the heat absorber 8 in a high humidity state. The heat absorber 8 is condensed to dehumidify and reaches the moisture absorbing portion 17. Therefore, the moisture releasing portion 16 of the dehumidifying rotor 11 that has been dried is rotated by the electric motor 14 that is a rotating means to become a moisture absorbing portion 17. The moisture absorbing portion 17 absorbs and dehumidifies the humidity that has not been dehumidified by the heat absorber 8. .

  The feature in this embodiment is the structure of the partition part 12. That is, the partition part 12 partitions the air path from the moisture release part 16 to the heat absorber 8 and the air path from the heat absorber 8 to the moisture absorber 17, and dehumidifies extending from the dehumidification rotor 11 toward the heat absorber 8. From the rotor side partition part 20, the heat absorber side partition part 21 extending from the heat absorber 8 toward the dehumidification rotor 11, and the connection partition part 22 that connects the heat absorber side partition part 21 and the dehumidification rotor side partition part 20. Forming. Here, the heat insulating means 23 is provided in the connection partition portion 22.

  In other words, a partition 12 is provided in the air path between the dehumidifying rotor 11 and the heat absorber 8, and the partition 12 is an air path from the moisture releasing unit 16 of the dehumidifying rotor 11 to the heat absorber 8 and dehumidifying from the heat absorber 8. The air passage to the moisture absorption part 17 of the rotor 11 is partitioned, and the partition part 12 extends from the dehumidification rotor 11 toward the heat absorber 8 and the dehumidification rotor side partition part 20 and extends from the heat absorber toward the dehumidification rotor 11. Since the heat absorber side partition portion 21 and the connection partition portion 22 that connects the heat absorber side partition portion 21 and the dehumidification rotor side partition portion 20 are formed, the heat insulating means 23 is provided in the connection partition portion 22. Further, it is possible to suppress the formation of ice between the dehumidifying rotor 11 and the dehumidifying rotor side partitioning portion 20 that is the partitioning portion 12.

  That is, the heat absorber 8 cools the heat absorber side partition portion 21 which is a partition portion of the air path between the dehumidification rotor 11 and the heat absorber 8, but the heat absorber side partition portion 21 and the dehumidification rotor side partition portion 20. Since the heat insulating means 23 is provided in the connecting partition portion 22 that connects the two, the cooling of the connecting partition portion 22 by the heat absorber 8 is reduced, and as a result, the cooling heat conducted to the dehumidifying rotor side partition portion 20 is suppressed. The generation of ice between the dehumidifying rotor side partition 20 and the dehumidifying rotor 11 can be suppressed. In conclusion, it is possible to prevent the opening of the dehumidification rotor 11 from being blocked by damaging or deforming the surface of the dehumidification rotor 11 with ice.

  According to these results, it is possible to suppress a reduction in the amount of air passing through the dehumidification rotor 11 due to the opening of the dehumidification rotor 11 and a decrease in the dehumidification capability.

  Moreover, as shown in FIG. 4, the dehumidification rotor side partition part 20 which is the partition part 12 has the upstream dehumidification rotor side partition part 20a located in the upstream of the rotation direction in the moisture release part 16 of the dehumidification rotor 11, and dehumidification. The downstream dehumidification rotor side partition part 20b located in the downstream of the rotation direction in the moisture release part 16 of the rotor 11 is formed, and the connection partition part 22 includes the upstream dehumidification rotor side partition part 20a and the heat absorber side partition part 21. Are formed from an upstream connection partition portion 22a, a downstream dehumidification rotor side partition portion 20b, and a heat sink side partition portion 21 connected to each other, and the downstream connection partition portion 22b faces the heat absorber 8. The upstream connecting partition 22 a is configured at the position of the outer edge of the heat absorber 8.

  Specifically, in the air path between the dehumidification rotor 11 and the heat absorber 8, the partition 12 extending from the rotor case 10 is connected to the dehumidification rotor side partition 20 extending from the dehumidification rotor toward the heat absorber. The heat absorber side partition portion 21 extending in the direction of the dehumidifying rotor from the cooler side, and the connecting partition portion 22 that connects the heat absorber side partition portion 21 and the dehumidifying rotor side partition portion 20 are formed.

  First, the dehumidification rotor side partition part 20 is formed from the upstream dehumidification rotor side partition part 20a and the downstream dehumidification rotor side partition part 20b. Here, the upstream dehumidification rotor side partition 20a is positioned upstream of the dehumidification rotor 11 in the rotational direction of the dehumidification rotor 16 of the dehumidification rotor 11, and is in contact with the frame 11a on the heat absorber side of the dehumidification rotor 11. An upstream flat plate portion 24 having a horizontally long flat plate shape, an upstream flat plate rising portion 25 extending from both sides in the longitudinal direction of the upstream flat plate portion 24 to the heat absorber, and a circumferential edge of a circular hole in the center of the rotor case And an upstream arc rising portion 26 having a substantially arc flat plate shape extending from a part of the arc to the heat absorber side. The downstream dehumidification rotor side partition 20b is positioned on the downstream side in the rotational direction of the dehumidification rotor 11 in the dehumidification section 16 of the dehumidification rotor 11, and is substantially horizontally long in contact with the frame 11a on the heat absorber side of the dehumidification rotor 11. It is formed of a flat plate-shaped downstream flat plate portion 27 and a substantially horizontally long flat plate-shaped downstream rising portion 28 extending from both sides in the longitudinal direction of the downstream flat plate portion 27 to the heat absorber side.

  Next, the heat absorber side partition portion 21 extends from the heat absorber 8 in the direction of the dehumidifying rotor so as to cover the upper surface of the heat absorber 8 and has a substantially horizontally long plate-shaped upper surface rising portion 29, and from the heat absorber 8 toward the dehumidifying rotor. Two side surface rising portions 30 having a substantially horizontally long plate shape extending so as to cover both side surfaces of the heat absorber are connected to each other. That is, the heat absorber side partition portion 21 has a substantially U-shape that covers the upper surface and both side surfaces of the heat absorber 8.

  Finally, the connection partition part 22 is formed of an upstream connection partition part 22a and a downstream connection partition part 22b. That is, the upstream connecting partition portion 22a includes the end portion 25a on the heat absorber side of one upstream flat plate rising portion 25 that is the upstream dehumidifying rotor side partition portion 20a, and the heat absorber side end of the upstream arc rising portion 26. The portion 26a is connected to the upper surface rising portion 29 which is the heat absorber side partition portion 21 and the end portion 30a on the dehumidification rotor side of one side surface rising portion 30. Further, the downstream connecting partition portion 22b includes an end portion 28a on the heat absorber side of one downstream flat plate rising portion 28 on the upstream side which is the downstream dehumidifying rotor side partition portion 20b, and an upper surface rising portion which is the heat absorber side partition portion 21. 29 and the end portion 30a on the dehumidification rotor side of one side rising portion 30 are connected. Here, the upstream connection partition portion 22a and the upstream dehumidification rotor side partition portion 20a are located at the outer edge portion of the heat absorber 8, and the downstream connection partition portion 22b and the downstream dehumidification rotor side partition portion 20b face the heat absorber 8. It is what is located.

  That is, the upstream connection partition part 22a is located at the outer edge part of the heat absorber 8, and the upstream connection partition part 22a and the upstream dehumidifying rotor side partition part 20a, which are the partition parts, are not located at positions facing the heat absorber 8. Therefore, compared with the downstream dehumidification rotor side partition part 20b, it can reduce that the upstream dehumidification rotor side partition part 20a is cooled by the heat absorber 8. FIG.

  Moreover, the heat insulation means 23b is provided in the heat absorber side of the downstream connection partition part 22b which is the connection partition part 22. FIG. Specifically, a heat insulating means 23b is provided between the heat absorber 8 and the downstream connecting partition portion 22b of the downstream connecting partition portion 22b facing the heat absorber 8 which is the connecting partition portion 22, that is, between the heat absorber 8 and the downstream connecting partition portion 22b. is there.

  Here, the air sucked into the main body case 3 from the air inlet 1 by the air blowing means 9 is heated by the radiator 6 and then further heated by the heater 18 to become high temperature and low relative humidity air, and the dehumidifying rotor 11 is released. The air is blown to the wet part 16. Part of the high-temperature air that has passed through the moisture release unit 16 hits the dehumidification rotor side of the downstream connection partition 22b, which is the connection partition 22, and flows to the heat absorber 8. After being cooled by the heat absorber 8, a part of the air hits the heat absorber side of the downstream connection partition portion 22 b that is the connection partition portion 22, that is, the heat insulating means 23 b and flows to the moisture absorption portion 17 of the dehumidification rotor 11. It is.

  That is, the dehumidification rotor side of the downstream connection partition part 22b which is the connection partition part 22 is warmed by the high-temperature air heated by the radiator 6 and the heater 18, and the heat absorber side of the downstream connection partition part 22b is the heat insulating means 23b. Thereby, since the air cooled with the heat absorber 8 does not hit directly, the temperature fall of the downstream connection partition part 22b can be suppressed.

  Further, as shown in FIGS. 4 and 5, a heat insulating means 23 a and a heat insulating means 23 c are provided on the heat absorber side and the dehumidifying rotor side of the upstream connecting partition portion 22 a which is the connecting partition portion 22.

  Specifically, the heat insulating means 23a and the heat insulating means 23c are provided on the heat absorber side and the dehumidifying rotor side of the upstream connecting partition portion 22a that is the peripheral portion of the heat absorber 8 that is the connecting partition portion 22.

  Here, the air sucked into the main body case 3 from the air inlet 1 by the air blowing means 9 is heated by the radiator 6 and then further heated by the heater 18 to become high temperature and low relative humidity air, and the dehumidifying rotor 11 is released. The air is blown to the wet part 16. The high-temperature air that has passed through the moisture release portion 16 flows to the heat absorber 8 with almost no contact with the dehumidification rotor side of the upstream connection partition portion 22 a that is the connection partition portion 22. After being cooled by the heat absorber 8, a part of the air hits the heat absorber side of the upstream connecting partition portion 22 a that is the connecting partition portion 22, that is, the heat insulating means 23 a and flows to the moisture absorbing portion 17 of the dehumidifying rotor. is there. A part of the cool air of the heat absorber 8 flows on the dehumidification rotor side of the upstream connecting partition 22a, but corresponds to the heat insulation means 23c on the dehumidification rotor side.

  That is, the dehumidification rotor side and the heat absorber side of the upstream connection partition portion 22a which is the connection partition portion 22 are not directly exposed to the air cooled by the heat absorber 8 by the heat insulating means 23a and the heat insulating means 23c. The temperature drop of 22a can be suppressed.

  The heat insulating means 23 is an independent foam heat insulating material. The material of the heat insulating material is polyethylene as an example.

  That is, since the heat insulating means 23 is an independent foam heat insulating material, air does not pass through the heat insulating material, so that the heat insulating performance can be improved. The heat insulating means 23 is formed of a heat insulating means 23a, a heat insulating means 23b, and a heat insulating means 23c.

  Moreover, the thickness of the heat insulating material on the heat absorber side of the upstream connecting partition portion 22a which is the connecting partition portion 22 is configured to be larger than the thickness of the heat insulating material on the dehumidifying rotor side of the upstream connecting partition portion 22a.

  That is, since the upstream connection partition part 22a is located in the outer edge part of the heat absorber 8, the upstream connection partition part 22a and the upstream dehumidification rotor side partition part 20a which are the downstream dehumidification rotor side partition part 20b are the heat absorber 8. Is not in a position opposite to. Therefore, by increasing the thickness of the heat insulating means 23b on the dehumidifying rotor side, the upstream connecting partition portion 22a which is the connecting partition portion 22 is not narrowed without narrowing the air path flowing from the moisture releasing portion 16 of the dehumidifying rotor 11 to the heat absorber 8. Temperature drop can be suppressed.

  Further, a heater 18 as a heating means is provided in the air path between the radiator 6 and the dehumidifying rotor 16 of the dehumidifying rotor 11, and the heater 18 is provided downstream in the rotational direction of the dehumidifying rotor 16 of the dehumidifying rotor 11. It is a positioned configuration. Specifically, a heater 18 as a heating means is provided in the air path between the radiator 6 and the moisture release portion 16 of the dehumidification rotor 11, and the rotation of the dehumidification rotor 11 in the moisture release portion 16 of the dehumidification rotor 11 is further performed. A heater 18 is provided on the downstream side in the direction.

  That is, since the heater 18 is provided near the downstream dehumidifying rotor side partitioning portion 20b and the downstream connecting partitioning portion 22b as the partitioning portion in the air path between the radiator 6 and the moisture releasing portion 16 of the dehumidifying rotor 11, the heater 18 Due to this heat generation, the downstream dehumidification rotor side partition portion 20b and the downstream connection partition portion 22b are warmed, and the temperature decrease of the downstream dehumidification rotor side partition portion 20b can be suppressed.

  In addition, the heater 18 as a heating means is configured at a position facing the connection partition portion 22. Specifically, the heater 18 which is a heating means is provided in the air path between the radiator 6 and the moisture releasing part 16 of the dehumidifying rotor 11, and the heater 18 is provided at a position facing the connecting partition part 22. It is.

  That is, since the heater 18 is provided in the air path between the radiator 6 and the moisture releasing portion 16 of the dehumidifying rotor 11 and facing the downstream connecting partition portion 22b which is a partition portion, Further, the downstream dehumidification rotor side partition portion 20b and the downstream connection partition portion 22b are further warmed, and the temperature decrease of the downstream dehumidification rotor side partition portion 20b can be suppressed.

The heat pump includes a compressor and a heat radiator sequentially provided downstream of the compressor, The radiator is formed by an expansion unit and a heat absorber, and is provided with a blower unit that blows air sucked into the main body case from the intake port to the exhaust port through the heat sink and the heat absorber.

Can be suppressed.

  In other words, the heat absorber cools the heat absorber side partition, which is the air path partition between the dehumidification rotor and the heat absorber, but the connection partition that connects the heat absorber side partition and the dehumidification rotor side partition. Since the heat insulating means is provided in the part, the cooling of the connecting partition part by the heat absorber is reduced, and as a result, the cooling heat conducted by the dehumidifying rotor side partition part is suppressed, and the dehumidifying rotor side partition part and the dehumidifying rotor are The generation of ice between them can be suppressed. In conclusion, it is possible to prevent the opening of the dehumidification rotor from being closed by damaging or deforming the surface of the dehumidification rotor with ice.

  According to these results, it is possible to prevent the air volume passing through the dehumidification rotor from being reduced and the dehumidification ability from being reduced due to the opening of the dehumidification rotor being blocked.

  Therefore, it is expected to be utilized as a dehumidifying device for home use or office use.
