The present invention relates to a dehumidifying and drying apparatus provided with a rotary dehumidifying element used for dehumidifying and drying in a closed room in a high humidity atmosphere such as a clothes storage room or a basement.

[0002]

2. Description of the Related Art In general, a ventilation opening is opened through a decorative grill on a wall surface or a ceiling surface of a bathroom or the like as a closed room in a house, and a ventilation fan is attached to a ventilation opening frame of the ventilation opening outside the room. This provides indoor ventilation.

In order to perform dehumidification / drying in a room, a suction port and an air outlet are separately provided on a wall surface or a ceiling surface, and a humid air in the room is removed by a dehumidifying / drying device installed outside the room. This is performed by sucking the air from the suction port for dehumidification and drying, and by blowing the dehumidified dry air into the room from the air outlet, whereby the bathroom is used as a drying room for clothes such as laundry. I have.

Conventionally, in this type of dehumidifying and drying apparatus,
