The dehumidification rotor 10 is configured in a honeycomb shape that allows ventilation in the axial direction where the adsorbent is supported. This adsorbent can hold a large amount of moisture if the relative humidity of the exposed air is high, and the relative humidity is low. In this case, the amount of water that can be held is reduced. Thus, if contact with a plurality of airs having different relative humidity is repeated, moisture adsorption / desorption is performed according to the difference in the amount of moisture that can be held by the adsorbent at each relative humidity. The dehumidification rotor has a moisture absorption area 10 a that adsorbs moisture in the air to the dehumidification rotor 10, and a moisture release area 10 b that releases the moisture adsorbed to the dehumidification rotor 10.

Room air is sucked from the suction port 2 by the blower 9, moisture is absorbed by the moisture absorption region 10a of the dehumidification rotor 10, and the dehumidified air is blown into the room from the outlet 4 as dry air (dehumidification air passage). Moisture absorbed by the dehumidification rotor 10 moves to the moisture release region 10 b by the rotational drive of the dehumidification rotor 10, and is released to the circulation air path 13 by heating of the heat generating unit 14. In the circulation air passage 13, the hot and humid air sent from the moisture release region 10 b of the dehumidification rotor 10 is blown to the heat exchanger 15 by the ventilation of the circulation fan 16. In the heat exchanger 15, the circulation air passage 13 and the blower 9 are sucked into the main body case 1 to exchange heat with the cooling air passage 23 that cools the heat exchanger 15, and the hot and humid air in the circulation air passage 13 is cooled. Water is condensed and collected in the water storage unit 6 as condensed water.

  The partition part 30 is provided with the 1st receiving part 31 which collects the dew condensation water in the circulation air path 13, and the 2nd receiving part 32 which collects the dew condensation water which drops along a support frame.

  The first receiving portion 31 is a recess in which the partition plate portion 30 is recessed downward. The depression is covered with the support frame 11 and the heat exchanger 15 so that a space is formed inside.

  The second receiving part 32 is arranged around the first receiving part 31. The second receiving portion 32 is surrounded by an annular waterproof wall 35 protruding upward from the partition plate portion 30. The waterproof wall 35 is an elongated plate and has a rib shape. A first receiving portion 31 and a second receiving portion 32 are disposed inside the waterproof wall 35.

  A space sandwiched between the support frame 11 and the partition plate portion 30 is a communication path 33 where a part of the lower lower surface portion 11 b of the support frame 11 and a part of the upper surface of the partition plate portion 30 are overlapped and fixed. . Specifically, the lower portion of the support frame 11 is provided with a lower surface portion 11b having a lid shape opened downward, and the lower end of the lower surface portion 11b and a part of the upper surface of the partition plate portion 30 are overlapped and fixed. . Thus, since a part of the lower end of the lower surface part 11b of the support frame 11 and a part of the upper surface of the partition plate part 30 are overlapped, this overlapping part, that is, the lower end of the overlapping lower surface part 11b. There is a slight gap between the upper surface of the partition plate portion 30 and the upper surface of the partition plate portion 30. Water can enter and leave the first receiving portion 31 and the second receiving portion 32 through this gap.

  FIG. 7 is a plan view of the partition plate portion as viewed from above the partition plate portion of the dehumidifying device in the embodiment of the present invention.
