Abstract

PURPOSE: To reduce heat loss and make a heat exchanger free from clamping and detaching by controlling the heat exchanger independent of a ventilator fan.
CONSTITUTION: An electric motor 14 for driving an exhaust fan 12 and a suction fan 13, a control switch 22 for this motor, a low speed motor 17 for rotating a heat exchanger 16, a control switch 23 for this motor, a contact 24 which turns on when either of push button switches 22a, 22b for strong or weak driving of the control switch 22 turns on and turns off when a push button switch 22c for stop turns off, these make a control electric circuit. Therefore, if a strong or a weak drive push button switch 22a or 22b and a drive push button switch 23a are turned on, the exhaust or the suction fans 12, 13, the heat exchanger 16 are driven, heat is exchanged, ventilation is carried out. When a strong or a weak drive push button switch 22a or 22b, a push button switch for stop 23b are brought into operation, both fans 12, 13 are driven but the exchanger 16 stops for ventilation only. Therefore, it is not necessary to remove the heat exchanger 16 in spring or autumn when it is not used.
