FIGS. 1 and 2 are configuration diagrams of a dehumidifying / humidifying apparatus according to a first embodiment of the present invention, in which (a) is a side view and (b) is a front view of a main part.

The structure of the dehumidifying / humidifying device according to the present embodiment is as follows. The honeycomb-shaped adsorbent 1 having a hygroscopic property and a gas permeability is cylindrical and connected to a drive motor 3.
Then, as the drive motor 3 rotates, the adsorbent 1
Rotates. The adsorbent 1 is not limited to a honeycomb shape,
Any material that can be ventilated, such as a lattice, a sponge, or a net, may be used.

The air blowing means 2a and 2b are installed on the downstream side (downwind side) of the air flow of the adsorbent 1 so as to generate (generate) the first and second air flows 4 and 5, respectively.

When the blowing means 2a operates, the room air is taken in, becomes the first air flow 4, passes through the adsorbent 1, and is exhausted outside through the ventilation passage 8. The ventilation passage 8 is insulated by a heat insulating material 14.

When the blowing means 2b is operated, the room air is taken in, and the second air flow 5 passes through the adsorbent 1 and is exhausted indoors.

The range in which the first air flow 4 and the second air flow 5 pass through the adsorbent 1 is cylindrical due to the partition wall 9 disposed upstream (upwind) of the adsorbent 1. Adsorbent 1

Further, a configuration may be adopted in which the airflow generated by one air blowing means installed on the upstream side of the adsorbent 1 is branched into two systems of airflows and is blown to the adsorbent 1.

The heating means 6 is arranged on the upstream side of the adsorbent 1 with respect to the air flow, and is connected to the heating means drive motor 7 via the partition wall 9. The heating means 6 rotates with the rotation of the heating means drive motor 7. The heating means 6 can move to a position for heating the first air flow 4 and a position for heating the second air flow 5 by rotating. That is, the first air flow is initially disposed at a position where the second air flow 5 is heated, and is rotated by 180 degrees to move to a position where the first air flow 4 is heated. Further, by rotating further 180 degrees or reversely rotating 180 degrees, the original second

The partition walls 10 are respectively installed on the downstream side of the adsorbent 1 with respect to the air flow, and each is connected to the heating means drive motor 7.

The partition walls 9c and 10 are formed so that the range in which the first air flow and the second air flow pass through the adsorbent 1 is not a semicircle obtained by dividing the cylindrical adsorbent 1 into two parts, that is, The area ratios are different. Specifically, the range through which the heated air flow passes is made smaller than the range through which the unheated air flow passes.

That is, the humidified first air flow 4 was dried outside the room, whereas the humidified second air flow 5 was exhausted indoors, while the first air flow 4 was dried outside. Since the ventilation path is different from the dehumidification for exhausting the second air flow 5 into the room, specifically, since the heating means 6 is removed from the ventilation path of the second air flow 5, the pressure loss is reduced. As the air volume of the second airflow increases and the transmission noise is more likely to be transmitted indoors, the output of the air blowing means 2b is reduced to reduce the air volume and reduce the blowing noise. Further, since the heating means 6 enters the ventilation path of the first air flow 4, the pressure loss increases and the air volume of the first air flow 4 decreases, so the output of the blowing means 2a is increased to increase the first air flow. Control is performed to increase the airflow of the airflow.

When ventilation is performed without humidification or dehumidification, the ventilation means 2a is controlled to the maximum output, and ventilation can be efficiently performed in a short time.
