PURPOSE: To shorten drying time by forming exhaust and feed ventilation flues, communicating a bathroom side return air intake on the feed ventilation flue, providing a heater, providing a ventilation flue, box compatible as a filter and providing a heat exchanger through which the feed and exhaust ventilation flues partially pass. CONSTITUTION: When a motor 11 having a blade 12 for exhaust and a blade 13 for feed is operated, air in a bathroom comes from a bathroom side intake 2, passes through the blade 12 for exhaust and a heat exchanger 10 and is exhausted from a room outside outlet 6. On the other hand, air outside the room comes from a room outside intake 7, passes through the heat exchanger 10, collects the heat of the exhausted air, joins air coming from the bathroom side return air intake 3, passes through a ventilation flue box 14 and heater 15 and is fed from a bathroom side outlet 4 into the bathroom. Thus, by providing the heat exchanger 10 and box 14, clothings in the bathroom as well as the bathroom itself can be dried in a short time and dust from the outside of the room can be prevented by the box 14 from entering the bathroom. |
