PURPOSE:To perform ventilation inside a car room so effectively in time of parking as well as to make the output of a solar cell chargable to a battery at need, by using the solar cell equipped outside a car as power source for a ventilator ventilating the car room inside. CONSTITUTION:A solar cell 21 and a control circuit 31 are built in a rear air spoiler 50 being attached to a rear part of an automobile, and a blower motor 11 of an air conditioner 10 is driven and controlled by the solar cell 21 and a battery 40 via the control circuit 31. The control circuit 31 is constituted of installing a circuit to be connected to the blower motor 11 via a contact of a relay RL1 after connecting the battery 40 via a manual switch SW1, a circuit to be connected to a timer T1 via a second contact of the relay RL1 and a circuit to be grounded via each output contact of a resistor R1 and the timer TM1 and a parallel connection of a condenser C1 and the relay RL1. With this constitution, the blower motor 11 is made alternately drivable at every specified time by the battery 40 and the solar cell 21. |
