Then, it is possible to ventilate multiple rooms with a simple configuration.

Further, if the control device is connected to a humidity sensor for detecting the humidity of the indoor room, it is possible to switch between ventilation operation and dehumidification operation based on the humidity information of the indoor room obtained from the humidity sensor. It is possible to dehumidify quickly and at low cost according to the environment.

Further, if the control device performs continuous ventilation operation at a certain humidity or higher and switches to dehumidification operation when the humidity falls below a certain humidity, optimum dehumidification can be performed with simple control. become.

Furthermore, the control device is connected to a humidity sensor for detecting the humidity of the indoor room, and when the humidity information of the indoor room obtained from the humidity sensor is above a certain humidity, dehumidifying operation is performed to obtain a constant humidity. If the dehumidifying operation is stopped when the temperature falls below the range, the humidity in the bathroom can be kept constant, and the mold can be kept in a state in which the generation of mold is always suppressed.

Furthermore, if the control device automatically starts the operation every set time and performs the operation within the set time, it is possible to prevent generation of new mold spores every time. Therefore, mold growth can be suppressed at low cost.

Further, by providing a drainage mechanism for draining the condensed water dripping from the evaporator, the condensed water can be discharged outdoors, and a member for discharging the condensed water indoors is required. Since it does not, it is possible to provide a dehumidifying / drying device that looks good.

Further, if the drainage mechanism has a pump for draining the condensed water dropped from the evaporator, the hose for discharging the drainage is arranged at a position higher than the drain tray for storing the condensed water. Even if it is done, the dew condensation water can be forcibly discharged, so that reliable drainage becomes possible.

Further, the control device is connected to a water level sensor provided in a drainage tray for storing the condensed water dropped from the evaporator, and controls the operation of the pump based on the water level information obtained from the water level sensor. By doing so, it is possible to drain the condensed water without overflowing the condensed water from the drain tray and without running the pump dry.

Furthermore, if the dehumidifying / drying device is attached to the bathroom and the condensed water drained by the drainage mechanism is drained to the drainage port of the bathroom by utilizing the back wall of the bathroom, it will be drained indoors. Therefore, the drainage hose and the like are not exposed outdoors, and a dehumidifying / drying device having a good appearance can be provided.

If an electric heater for raising the temperature of the indoor room is provided, the speed of dehumidifying the indoor room is increased, and effective dehumidification is possible.

If the air circulation device uses the heat radiation of the compressor to raise the temperature of the indoor room, it is possible to perform efficient dehumidification with an inexpensive structure.

Further, if the compressor is provided in the circulation air passage of the air circulation device, efficient dehumidification can be achieved with a simple structure.

If the compressor is an AC or DC inverter motor, the capacity of the compressor can be varied, and it is not necessary to always operate with the maximum capacity as in the conventional case, and running costs can be reduced. A dehumidifying / drying device can be provided.

Furthermore, if the ventilation device is operated when the refrigeration cycle is switched from the dehumidifying operation to the defrosting operation, dehumidification can be performed more quickly without interrupting dehumidification indoors.

Further, by providing an air flow direction adjusting plate capable of varying the blowing direction of the air circulated from the air circulating device to the indoor room, the dehumidified wind is blown toward the wall surface, so that it becomes damp. The wall can be dried quickly.

Further, if the wind direction adjusting plate is provided on the decorative plate attached so as to cover the dehumidifying / drying device from the indoor room, it is not necessary to newly provide a member for holding the wind direction adjusting plate, and the structure is simple. With this configuration, dehumidified wind can be blown toward the wall surface, and the wet wall surface can be quickly avoided.

By radiating heat from 0, the air is further warmed and, as a result, is circulated into the bathroom B at a temperature higher than the temperature of the air when it is inhaled.

As described above, since the air having a lower humidity and a higher temperature than when inhaled is circulated, the dehumidification in the bathroom B is promoted, the moisture in the bathroom B can be removed, and the inside of the bathroom B can be removed. By hanging your clothes on, you can dry them when you are not in the bathroom.

Since the suction air passage 10 is provided with the humidity sensor 47, the information on the humidity in the bathroom B is controlled by the controller 23.
