Problems solved by technology
[0009] Another object of the present invention is to provide a solution to the problem that the workability of the wiring is reduced due to the conventional motor pump and the sensor being separated separately and the wiring is connected to the cleaning liquid bucket, by installing the water level sensor integrally on the motor pump On the other hand, not only the workability of the wiring is easy, but also the wiring is simplified, so that the defect rate can be reduced. The motor pump for cleaning liquid with a water level sensor attached

The present invention relates to a motor pump for washer fluid, having a fluid level sensor attached thereto. More particularly, a fluid level sensor for sensing the residual amount of washer fluid stored in a washer fluid tank and outputting a sensing signal is integrally mounted to a motor pump for washer fluid, so that a driver can identify the residual amount of the washer fluid through the instrument panel of a vehicle and thus can fill up the washer fluid when the washer fluid is insufficient. The fluid level sensor integrally mounted to the motor pump can not only facilitate wiring work, but can also simplify wiring, thereby reducing the defect rate of the wiring. Also, the motor pump for washer fluid and the fluid level sensor which are integrally manufactured can contribute to a reduction in production costs. Since the fluid level sensor for sensing the residual amount of washer fluid and outputting a sensing signal is manufactured by any one selected from a combination of a buoyant magnet and a Hall sensor, a combination of a buoyant magnet and a reed switch, and a combination of a Hall sensor and a buoyant device to which a magnet is attached, a performance improvement can be achieved using a Hall sensor which has reliability as a type of magnetic sensor.
Description
Technical field [0001] The present invention relates to the integrated installation of a water level sensor for detecting the residual amount of washing liquid stored in a washing liquid tank and outputting a detection signal on a motor pump, so that the driver can confirm the residual washing liquid through the dashboard of the vehicle In order to supplement when the cleaning fluid is insufficient, the conventional motor pump and the sensor are separated separately and the wiring is connected to the cleaning fluid tank, which reduces the workability of the wiring. By installing the water level sensor in one piece On the motor pump, not only the wiring is easy to work, but also the wiring is simplified, which can reduce the defective rate, and because the motor pump for the cleaning liquid and the water level sensor are manufactured as an integrated type, the manufacturing cost can be reduced, and it is used for detecting the cleaning liquid. The water level sensor that outputs ...
