PURPOSE: To enable an efficient recycling treatment of a rotary dehumidifying element to be carried out and a dehumidifying or drying treatment for wet indoor air with the rotary dehumidifying element through a convenient blowing system, to provided a small-sized entire device and to reduce the cost.
CONSTITUTION: Indoor air A fed from a suction port 3 of a case main body 1 is passed through a cylindrical rotary dehumidifying element 20 by a forced circulating mechanism under an operation of a single blower so as to adsorb moisture, thereafter the air B is returned back to the room from the outlet 4, hot air is passed through the rotary dehumidifying element having adsorb moisture to desorb moisture. A recycling chamber 31 for passing hot air through the rotary dehumidifying element is arranged at a secondary side of a treatment chamber 7, and a discharging chamber 33 for discharging hot air out of the case main body is arranged at a primary side 7A of the treatment chamber and then the discharging pipe 34 connected to the discharging chamber 33.
