As is apparent from the above description, according to the present invention, a suction port and a blowout port are provided on the front surface of the case body facing the indoor side, and the inside of the room introduced from the suction port of the panel surface is provided. Air is passed through the dehumidifying element of the rotary type provided in the case body by the forced circulation mechanism by the blowing means consisting of the centrifugal blower to dehumidify the moisture in the air.
After drying, the dehumidified / dried air is returned to the room through the air outlet, and high-temperature air is passed through the rotary dehumidifying element to which moisture has been adsorbed to desorb the moisture from the rotary dehumidifying element. Since it is provided with a regeneration processing means for causing the air in the room to be directly exhausted and a ventilation means for directly exhausting the indoor air, during the dehumidification / drying operation,
The drying and the regeneration treatment of the rotary dehumidifying element can be simultaneously and continuously performed.

Moreover, the inside of the case body is divided into at least a primary zone communicating with the suction port, a tertiary zone communicating with the air outlet, and a secondary zone adjacent to the tertiary zone and the primary zone. An air blower consisting of a blower circulates the room air in the case body from the suction port in order through the primary zone, secondary zone and tertiary zone to the outlet, and this blower passes through the secondary zone to the tertiary zone. Since the air flow path is formed so that the moisture in the air that reaches the air is brought into contact with the cylindrical rotary type dehumidifying element to be adsorbed, the simplification of the air blowing system as a whole,
The size of the device can be reduced.

Further, since the regeneration air heated and recovered by the heat recovery means is brought to the tertiary zone in the case body and exhausted from the outlet through the drying / heating switching means, the heating means is connected to the heating means. It is possible to easily heat the interior of the room by changing over, and to improve the drying efficiency during the dry operation, while maintaining the comfort of heating the bathroom during the winter bathing.

Further, the regeneration means has a regeneration chamber arranged in a region corresponding to the regeneration treatment site and the heat recovery treatment site on the tertiary zone side of the rotary dehumidification element, and the heat recovery of the rotary dehumidification element is performed in this regeneration chamber. An inlet for the diverted air after adsorbing water from the treatment site and an outlet for turning the diverted air to the regeneration treatment site side of the rotary dehumidifying element are formed by partition walls, and this inlet is also provided. While an electric heater is provided to heat the diverted air after moisture adsorption from the heat recovery processing part of the rotary dehumidification element, the drying / heating switching means is provided on the side wall on the downstream side of the electric heater facing the tertiary zone side of the regeneration chamber. The provided exhaust port is formed by a switching damper whose opening and closing can be controlled, and the regeneration air heated by the electric heater is made to reach the tertiary zone when the switching damper is open. It is possible to reduce the size of the entire apparatus according to space saving in the chamber.

Furthermore, since a heating means for heating the air dehumidified and dried by the dehumidifying means and exhausting the heating air from the outlet is provided in the tertiary zone in the case body, this auxiliary function is provided. The heating means promotes indoor heating.

The rotary dehumidifying element is rotatably supported and disposed between the seal panel member and the regeneration chamber, which are fastened to each other, and the spacer member is interposed between the seal panel member and the regeneration chamber. Since a gap is formed between the rotary dehumidifying element and the seal panel member and the regeneration chamber with the interposition of the rotary dehumidifying element, even if uneven rotation occurs in the rotary dehumidifying element during operation, the rotary dehumidifying element can be used. Since the element does not come into contact with the reproduction chamber or the seal panel member, it is possible to prevent an increase in rotation torque and wear of the contact surface.

Further, in the present invention, since the spacer members are provided at three points around the rotary type dehumidifying element at substantially equal intervals, a stable mounting strength against deformation of the regeneration chamber due to heat is provided. Obtainable.
