Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a bathroom in a building, for example.
The present invention relates to a dehumidifying / drying device equipped with a rotary dehumidifying element used for dehumidifying and drying a highly humid atmosphere sealed room such as a clothes storage room or a basement.

[0002]

2. Description of the Related Art Generally, for example, on a wall surface or ceiling surface of a bathroom as a closed room at home, a ventilation port is opened through a makeup grill, and a ventilation fan is attached to the outside of a ventilation frame in a mounting frame provided in the ventilation port. By installing it, the room is ventilated.

Further, in the case of performing such dehumidification / drying of the room, a suction port and a blowout port are separately provided on the side wall surface or the ceiling surface, and the dehumidifying / drying device installed outside the room wet air in the room. This is done by sucking air through the suction port to dehumidify and dry it, and by blowing out the dehumidified dry air into the room from the air outlet, so that the bathroom can be used as a drying room for clothes such as laundry. ing.

Conventionally, in this type of dehumidifying / drying device,
Circulating air that blows dry air after the humid air in the room that has been sucked in through the suction port passes through the rotary dehumidifying element provided in the case body to cause the moisture to be adsorbed into the room through the air outlet. In addition to the forced circulation mechanism, the high temperature air is sent to the rotary dehumidifying element to which moisture is adsorbed, so that the rotary dehumidifying element desorbs water and regenerates the rotary dehumidifying element. Some have a configuration as described above.

[0005]

However, in the dehumidifying / drying device having the above-mentioned conventional structure, the forced circulation mechanism for the circulating air for sucking in the humid air in the room and blowing out the dried air after dehumidification, and the regenerating unit for regeneration. Since the air-blowing function that takes in and exhausts air is performed by separate air-blowing mechanisms, two dedicated air-blowing machines are required, the air-blowing system becomes complicated, and the overall size of the device only increases. Not only will it cost more.

Moreover, if the regenerating air is directly taken in from the outside, the temperature and humidity of the outdoor air change greatly, it is difficult to control the heating by the heater, and it is necessary to increase the capacity of the heater.
Further, since the outdoor air is often contaminated, the rotary dehumidifying element is heavily contaminated, which adversely affects dehumidifying / drying performance and durability.

In order to reduce the motor torque, the rotation driving means for such a rotary dehumidifying element is:
It has a configuration in which a driving belt is hung and meshed between the outer peripheral surface of the rotary type dehumidifying element and the drive motor. Forming the meshing teeth is not only difficult in design, but also costly.

[0008]

A tension spring is used to maintain tension in the driving belt.

[0011]

That is, according to the present invention, by adopting the above-mentioned structure, a mounting opening portion having a suction / blowing function is provided on the front surface of the case body, and the air in the room introduced from the suction opening of this mounting opening portion is provided. Is passed through a rotary type dehumidifying element that is rotated by the rotation drive means provided in the case body by a forced circulation mechanism with a single blower to adsorb water, and then this air is returned from the outlet to the chamber. At the same time, high-temperature air is passed through the rotary dehumidifying element to which the moisture has been adsorbed, to allow the rotary dehumidifying element to desorb water.
Since it has a ventilation function to directly exhaust the indoor air, during the dehumidification / drying operation, the dehumidifying / drying of the humid air in the room by the rotary dehumidifying element and the regeneration processing of the rotary dehumidifying element are performed continuously at the same time. Can be done.

Moreover, since the forced circulation mechanism consisting of a single blower is used to simultaneously circulate the indoor air and simultaneously supply and exhaust the regenerated air by taking in the air, it is possible to reduce the weight by simplifying the blowing system. .

Further, a plurality of projections are provided on the outer peripheral surface of the rotary type dehumidifying element as the rotation driving means of the rotary type dehumidifying element.
Since at least one of these protrusions can be meshed with the tooth portion of the driving belt that is stretched between the drive motor and the drive motor, the entire outer peripheral surface of the rotary dehumidifying element is as before. In addition, it is not necessary to form teeth that mesh with the driving belt at the same pitch.

Furthermore, since the tension of the driving belt is maintained by the tension spring, the protrusions of the rotary dehumidifying element and the teeth of the driving belt are surely meshed with each other to prevent the belt from slipping. As a result, low rotation of the rotary dehumidifying element can be stably performed.
