[0001]

BACKGROUND OF THE INVENTION The present invention relates to a bathroom for a building,
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, for example, 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 provided on a mounting frame provided in the ventilation opening on the outside of the room. By installing it, the room is ventilated.

In order to perform such indoor dehumidification and drying, a suction port and an air outlet are separately provided on a side wall surface or a ceiling surface, and the indoor humid air is installed by a dehumidification / drying device installed outside the room. Is carried out by sucking the air from the suction port to dehumidify and dry, 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. ing.

Conventionally, in this type of dehumidifying and drying apparatus,
Circulating air that allows the humid air in the room sucked from the suction port to pass through the rotary type dehumidifying element provided in the case main body to cause the moisture to be adsorbed, and that the dry air is blown into the room from the outlet through the outlet. The forced circulation mechanism is provided, and high-temperature air is supplied to the rotary dehumidifying element to which moisture has been adsorbed, thereby causing the rotary dehumidifying element to desorb moisture and regenerate the rotary dehumidifying element. There is a device having a configuration as described above.

[0005]

However, in the dehumidifying / drying apparatus having the above-mentioned conventional structure, a forced circulation mechanism for circulating air for sucking in humid air in the room and blowing out dry air after dehumidification, Since the air blowing function for taking in and discharging air is performed by separate air blowing mechanisms, two dedicated air blowers are required, which complicates the air blowing system and increases the size of the entire device. Instead, it becomes expensive.

Moreover, if air for regeneration is directly taken in from outside the room, the temperature and humidity of the outdoor air change greatly, making it difficult to control the heating by the heater and increasing the capacity of the heater.
In addition, since there is much dirt in the outdoor air, the rotary dehumidifying element is heavily stained, which adversely affects the dehumidifying / drying performance and durability.

In order to reduce the motor torque, the rotation driving means for such a rotary type dehumidifying element is designed to reduce the motor torque.
The rotating dehumidifying element has a configuration in which a driving belt is stretched and meshed between the outer peripheral surface of the rotating dehumidifying element and the driving motor, but the entire outer peripheral surface of the rotary dehumidifying element has the same pitch as the driving belt. Forming the meshing teeth is not only difficult in design, but also increases the cost.
