2. Description of the Related Art Generally, a ventilation opening is opened through a makeup grill on a wall surface or ceiling surface of a bathroom or the like as a closed room in a home, and a ventilation fan is attached to the ventilation opening frame of the ventilation opening outside the room. As a result, the room is ventilated.

Further, in the case of performing such dehumidification / drying of the room, a suction port and a blowout port are separately provided on the side wall surface or the ceiling surface, and the dehumidifying / drying device installed outside the room wet air in the room. This is done by sucking air through the suction port to dehumidify and dry it, and by blowing out the dehumidified dry air into the room from the air outlet, so that the bathroom can be used as a drying room for clothes such as laundry. ing.

Conventionally, in this type of dehumidifying / drying device,
Circulating air that blows dry air after the humid air in the room that has been sucked in through the suction port passes through the rotary dehumidifying element provided in the case body to cause the moisture to be adsorbed into the room through the air outlet. In addition to the forced circulation mechanism, the high temperature air is sent to the rotary dehumidifying element to which moisture is adsorbed, so that the rotary dehumidifying element desorbs water and regenerates the rotary dehumidifying element. Some have a configuration as described above.

[0005]

However, in the dehumidifying / drying device having the above-mentioned conventional structure, the forced circulation mechanism for the circulating air for sucking in the humid air in the room and blowing out the dried air after dehumidification, and the regenerating unit for regeneration. Since the air-blowing function that takes in and exhausts air is performed by separate air-blowing mechanisms, two dedicated air-blowing machines are required, the air-blowing system becomes complicated, and the overall size of the device only increases. Not only will it cost more.

Moreover, if the regenerating air is directly taken in from the outside of the room, the temperature and humidity of the outdoor air change greatly, it is difficult to control the heating by an electric heater, the capacity of the heater needs to be increased, and the drying efficiency decreases. Further, since the outdoor air is often contaminated, the rotary dehumidifying element is heavily contaminated, which adversely affects dehumidifying / drying performance and durability.

An object of the present invention is to enable efficient dehumidification / drying treatment of indoor moist air by a rotary type dehumidifying element and regeneration treatment of a rotary dehumidifying element by a simple blowing system, and at the same time, the entire apparatus. Another object of the present invention is to provide a dehumidifying / drying device capable of achieving downsizing and cost reduction, and also capable of heating a room.
