Abstract
A windshield washing and deicing system comprising a reservoir for containing washer fluid having a sealed container supported therein. A pump is effective to transfer washer fluid from the reservoir to the container and from the container to a plurality of nozzles located adjacent a vehicle window. A conduit is located in the reservoir for carrying heated engine coolant through the reservoir to heat the washer fluid therein. An electrical resistance wire is provided for further heating the washer fluid in the container whenever the temperature of the fluid in the container is below a predetermined minimum to quickly deice the vehicle window.
Claims11
A window washing system for a motor vehicle having a battery and a liquid cooling system for the motor in which the cooling liquid becomes warm as a result of heat exchange with the motor, comprising:

- (b) a reservoir for containing washer fluid;
- (c) a container having an inlet connected to said reservoir and an outlet connected to said nozzle means;
- (d) pumping means for transferring washer fluid from said reservoir into said container and from said container to said nozzle means;
- (e) means for circulating the warm cooling liquid from the motor cooling system into a heat exchange relationship with the washer fluid inside said reservoir to thereby heat the fluid;
- and
- (f) means for heating the washer fluid in said container when the temperature of the washer fluid in said container is less than a predetermined minimum.
