Abstract
When a washer system for a vehicle is activated, a first pumping device and a second pumping device supply a first discharge nozzle and a second discharge nozzle with a cleaning liquid, respectively, so that the cleaning liquid is discharged toward a right headlamp and a left headlamp, respectively. Hence, it is possible to reduce the size (a reduction of capacity) of the first pumping device and the second pumping device. In addition, the first pumping device and the second pumping device can supply front nozzles and a rear nozzle with the cleaning liquid, respectively, and therefore, the overall washer system for a vehicle does not need any additional pumping device.
Claims10
A washer system comprising:
- a tank for storing cleaning liquid;
- a first discharge nozzle, which receives the cleaning liquid from the tank and discharges the cleaning liquid to a right headlamp of a vehicle;
- a second discharge nozzle, which receives the cleaning liquid from the tank and discharges the cleaning liquid to a left headlamp of the vehicle;
- a front nozzle, which receives the cleaning liquid from the tank and discharges the cleaning liquid to a front glass of the vehicle;
- and
- a pumping apparatus, which is connected to the tank, the first discharge nozzle, the second discharge nozzle and the front nozzle and pumps the cleaning liquid of the tank to the first discharge nozzle, the second discharge nozzle and the front nozzle, wherein the pumping apparatus includes:
- a first pumping device, which includes two outlet openings and selectively discharges the cleaning liquid through a corresponding one of the two outlet openings that is selected depending on an operational state of the first pumping device, wherein one of the two outlet openings of the first pumping device is connected to one of the first and second discharge nozzles to supply the cleaning liquid to the one of the first and second discharge nozzles, and the other one of the two outlet openings of the first pumping device is connected to the front nozzle to supply the cleaning liquid to the front nozzle;
- and
- a second pumping device, which includes at least one outlet opening for discharging the cleaning liquid from the second pumping device, wherein one of the at least one outlet opening is connected to the other one of the first and second discharge nozzles to supply the cleaning liquid to the other one of the first and second discharge nozzles.
