PURPOSE:To prevent a car parked in the sun from abnormal rise of temperature inside by constructing to fix an air exhaust device provided inside with a small- sized sirocco fan and a small-sized motor drivable by a solar battery between a car window glass groove and an upper brim of the glass. CONSTITUTION:For parking a car, an exahust air device 7 is fixed with its upper side 6 fitted in a glass groove and its lower side 10 on the upper brim of a glass. In this way, a motor is driven by the electric power generated by an unillustrated solar battery to rotate a sirocco fan 4 and the air inside the car is exhausted to the outside as arrows show to ventilate the car for preventing the rise of temperature inside the car. In this case, as dry cells are contained inside, the device can be used for a smoke-exhausting device at a usual time. |
