Can be done That.

Moreover, the interior 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 heating means for heating the air dehumidified and dried by the dehumidifying means and exhausting the heating air from the blowout port is provided in the tertiary zone in the case body, by switching to the heating means. It is possible to easily heat the interior of the room and improve the drying efficiency during the dry operation, while maintaining the comfort of heating the bathroom during the winter bathing.

Further, the air on the way from the secondary zone to the tertiary zone is introduced and passed through the rotary type dehumidifying element on the regeneration means side in the reverse feeding state, and this air is heated by the heating device of the regeneration means. The first drying / heating switching means is provided in the exhaust means, and the second drying / heating switching means for introducing the heated air heated by the first drying / heating switching means into the tertiary zone and exhausting it from the outlet is provided. Since it is provided in the reproducing means, the room heating is promoted by the heating means as the auxiliary function.
