Abstract
An automobile ventilator which is a conventional ventilating device and a conventional air cleaning device combined into one. The ventilator structure has an air blowing passage opening into a passenger room of the vehicle. Through the air blowing passage comes out air blown by an impeller provided at the passage. There are further two passages to guide air to the impeller; one is a ventilation passage communicating outside the vehicle body while the other is a circulation passage opening into the passenger room. A damper is provided between the two passages in hinge fashion to selectively close either one of the two passages. This damper is controlled by manipulating the ignition switch such that the ventilation passage is closed on engine start whereas the circulation passage is closed when the engine is stopped. The impeller is driven alternately by first and second drive circuits. The first drive circuit is placed in an operative condition when the ignition switch is thrown to ON position whereas the second drive circuit is placed in an operative condition when the ignition switch is thrown to OFF position.
