PURPOSE:To prevent the adhesion of the water drop to the window glass by coating the window glass with the water-repellent agent then blowing the air from the end face of the window glass. CONSTITUTION:The water-repellent agent is applied on the window glass of a car. Upon driving of the car, the air is compressed by a wind collector. In other word the air will blow up the front glass face then is compressed by a defroster 5. The compressed air will blow down the rear window face. In order to increase the wind speed at this time, the area ratio between the inlet and the outlet of the wind collector 3 must be increased. For example if the gap at the inlet is 20mm. while the gap at the outlet is 0.5mm., the wind speed is increased by 40 times. |
