PURPOSE: To dry clothing in a bathroom and the bathroom in a short time by forming a supply ventilation path and an exhaust ventilation path inside a main body, providing the supply ventilation path with a heater and a fan motor for supply, providing the exhaust ventilation path with a fan motor for exhaust, providing a heat exchanger at the crossing of ventilation pathes and providing opening/closing dampers on the supply ventilation path side and exhaust ventilation path side of a communication port. CONSTITUTION: An exhaust ventilation path 8 from a bathroom side intake 2 to an outside outtake 6 and a supply ventilation path 9 from an outside intake 7 to a bathroom side outtake 4 are formed inside a main body 1. When a fan motor 12 for supply and a fan motor 11 for exhaust are operated, bathroom air is taken in from the bathroom side intake 2 and exhausted from the outside outtake 6 after heat exchange through the fan motor 11 for exhaust and a heat exchanger 10. Outside air is taken in from the outside intake 7, mixed with air from a bathroom side return air intake 3 after heat exchange through the heat exchanger 10, warmed by a heater 13 through the fan motor 12 for supply and supplied from the bathroom side outtake 4 into the bathroom. Thus, the clothing in the bathroom and the bathroom itself can be dried in a short time. |
