PURPOSE:To obtain forced ventilation without using power fo the engine, battery or the like on stopping or parking of a vehicle by actuating a driving motor of a ventilating fan disposed in a duct communicating between the inside and outside of the vehicle by the output of a solar battery mounted on the vehicle so as to ventilate the passenger compartment of the vehicle. CONSTITUTION:A ventilator 12 is opened to complete communication between a passenger compartment M and the outside air W1. A solar battery 9 rotates a driving motor 2 to cause a ventilating fan 3 connected and operatively associated therewith to suck in-car air W2 from an upper opening 5 and to exhaust the air through an exhaust duct from an air outlet 8 of the vehicle body, and the outside air is introduced into the passenger compartment M thereby to ventilate it. The driving motor 2 starts rotation, if the output of the solar battery module 9 is above a predetermined value and constant output is possible, if the illuminance is above a predetermined value. The output is obtainable in almost all cases of the daylight. Therefore, even if the engine is stopped, the passenger compartment M can be ventilated, using no battery, with windshields closed. |
