Apparatus for washing the window glass of a vehicle
First Claim
1. An apparatus for washing window glass of a vehicle, comprising a main tank for washing fluid, an outlet in a lower portion of said tank, an insulated container having a cover on an upper end, said container with said cover being positioned relative to said tank such that said cover is physically lower than the tank outlet, a first conduit extending from said tank outlet and through said container cover to a lower portion of said container, an electrical heating element within the lower portion of said container, a spray nozzle adjacent said window glass, an insulated second conduit extending from the upper end of the container to said spray nozzle for conducting heated fluid from the upper end of the container to said spray nozzle, and a pump in said first conduit for pumping fluid from said container to said spray nozzle, whereby the position of said container relative to said tank enables fluid to drain by gravity from the tank into the container to insure that the container remains full of fluid.

Abstract
An apparatus for washing the window glass of a vehicle comprising an intermediate container having an insulated construction and an electric heater which is connected to both a main tank for storing unheated washing fluid and an outlet from which the heated washing fluid is sprayed onto the glass. When the vehicle is turned on, the heater is turned on as well. Thus, with the vehicle in operation, the washing fluid is continually heated to a required temperature and held in the insulated intermediate container. As a result, it is possible to spray a required quantity of heated washing fluid at any time without excessive loading strain on the vehicle'"'"'s battery and without excessive power consumption.
