Window washer for vehicle |
摘要 |
A window washer comprises a washer liquid jet nozzle provided under a windshield glass of a vehicle so as to be directed thereto for periodically deflecting the jetting direction of the washer liquid horizontally by the fluidic self-oscillating operation thereof, a pump provided in a washer liquid passage connecting the jet nozzle to a washer liquid tank for pressurizing the washer liquid and sending the pressurized washer liquid, a driving motor for driving the pump and a motor control circuit for applying a square pulse shaped voltage to the motor. The motor control circuit periodically operates the pump so that the discharge pressure thereof periodically changes. Consequently, the jetting direction of the washer liquid jetted from the jet nozzle is periodically deflected horizontally and vertically.
