However, in such a conventional bathroom ventilation and drying system, a ventilation dryer having two fans, a circulation fan and a ventilation fan, is required, so that the ventilation drying system is required. There was a problem that the size of the machine increased and the weight increased, and it took time to reinforce the bathroom ceiling.

[0005] In addition, the design of the door is restricted because it is necessary to provide a ventilation gusset on the bathroom door. In addition, when ventilation is performed, since cold air flows into the bathroom from the ventilation gallery, there is a problem that if ventilation is performed during bathing, the cold air will hit the bather.

Accordingly, the present invention focuses on the above-mentioned problems, and can reduce the size and weight of the ventilation dryer and also prevent the design of the bathroom door from being restricted by the ventilation gusset. It is an object of the present invention to provide a bathroom ventilation / drying system capable of preventing cold air from hitting a bather during bathing.

According to the first aspect of the invention, when the blower is operated, the air in the bathroom flows into the intake chamber of the housing from the intake port, and is discharged outside through the exhaust duct. Accordingly, the air pressure in the bathroom decreases, so that air from a room other than the bathroom flows into the outlet chamber of the housing through the intake duct, and flows out of the outlet from the bathroom. At this time, when the heater is activated, warm air flows out of the outlet through the bathroom, and when the heater is not activated, normal-temperature air flows out of the outlet through the bathroom. In other words, when heating the bathroom, or when drying the laundry dried in the bathroom or the bathroom, it is effective to operate both the blower and the heater to raise the room temperature, which is effective. Only turning on saves energy.
