(Embodiment 1)
As shown in FIG. 1, a main body case 1 having an intake port 4 and an exhaust port 6, a dehumidifying rotor 2 having a moisture absorbing portion 2 b and a moisture releasing portion 2 a in the main body case 1, and the dehumidifying rotor 2 are rotated. The rotating means 3 to be moved and the first blower 7 are provided.

  The first air blower 7 blows air to the first air passage b. The first air passage b has a configuration in which an air inlet 4, a heat exchanger 5 to be described later, a moisture absorbing portion 2 b of the dehumidifying rotor 2, and an exhaust port 6 are sequentially provided.

  That is, the air sucked from the air inlet 4 is passed through the moisture absorbing portion 2b of the dehumidifying rotor 2 through the outer surface of the heat exchanger 5 described later, thereby allowing the air sucked from the air inlet 4 to be absorbed. The air is adsorbed, that is, dehumidified by the moisture absorbing portion 2 b of the dehumidifying rotor 2, and the dehumidified air is exhausted out of the main body case 1 through the exhaust port 6.

  Further, a moisture absorption path a is provided in the main body case 1.

  The moisture absorption path a includes a moisture release portion 2a of the dehumidification rotor 2, heat generation means 9 provided on the windward side of the moisture release portion 2a, a heat exchanger 5 provided on the leeward side of the moisture release portion 2a, and It has the structure which has the 2nd air blower 8 which circulates the air in the moisture absorption path | route a.

  That is, first, the air in the moisture absorption path a is heated by the heat generating means 9 to be in a high temperature and low relative humidity state, and blown to the moisture releasing portion 2 a of the dehumidifying rotor 2.

  Here, since the air at a high temperature and a low relative humidity passes through the moisture releasing portion 2a of the dehumidifying rotor 2, the moisture of the moisture releasing portion 2a of the dehumidifying rotor 2 is released to this air.

  Next, the air containing the moisture and having a high relative humidity is blown into the heat exchanger 5.

  Here, the heat exchanger 5 is located in the first air passage b, and has a moisture absorption path a inside the heat exchanger 5.

  That is, in the heat exchanger 5, air having high relative humidity including moisture is blown from the moisture release portion 2 a of the dehumidifying rotor 2 through the moisture absorption path a, and on the outer surface of the heat exchanger 5. The air sucked from the air inlet 4 of the main body case 1 is blown through the first air passage b.

The following structure is provided so as to protrude from each other.

  As shown in FIG. 4, when the heating state applied to the dehumidifying rotor 2 is simply expressed, it can be seen that the heating state is different from the conventional one.

  In the above configuration, a gap of 0.5 mm or less is formed in a step shape between the substantially fan-shaped lid 12 that covers the opening surface of the box 10 and the dehumidification rotor holding frame 19, and the notch 15 is formed in the inner frame 18. Even if it provides, the dehumidification capability fall can be prevented by suppressing the leakage of the heated warm air very little by the function of the outer frame part 16 and the connection part 17.

  Further, by providing the notch 15 on the upstream side in the rotation direction of the dehumidifying rotor 2, it is possible to reliably preheat the dehumidifying rotor 2, so that it is possible to prevent warping of the dehumidifying rotor 2 due to thermal shock. . In addition, the dehumidification amount can be improved by using parts that have not been used successfully.
