Embodiment Construction

[0041] Now refer to figure 1 , the vehicle 10 may provide a window 12, such as a windshield, positioned behind and above a washer system nozzle 14 oriented to provide a spray 16 of washer fluid on the window 12 to Wiper blades 18 are used for cleaning as is generally understood in the art. Similarly (but not shown), nozzles 14 may be positioned adjacent to other windows 12, including windows on headlight lenses, cameras and radar, ultrasonic, etc., and the like.

[0042] Now refer to figure 2 , each nozzle 14 may provide a nozzle 20 directing a stream of washer fluid 21 toward the adjacent window 12 and generally facing rearwardly relative to the direction of the advancing vehicle. The nozzle 20 may communicate through a standpipe 22 extending generally along the axis 19 with a feed pipe 24 attached to a flexible washer fluid hose 25 running from a washer pump 27 and A fluid storage tank 29 extends and / or leads to the downstream nozzle 14 . Although standpipe 22 generally...

Background technique [0004] Window washer systems, such as those used on windshields, may be used in conjunction with vehicle windshield wipers to spray a cleaning fluid on the windshield during activation of the wipers. During winter, antifreeze materials such as ethanol can be added to the washer fluid to prevent the washer fluid from freezing. During the winter, even if ethanol has been added to the washer fluid, washer fluid nozzles that are in the airstream and exposed to ambient moisture can freeze completely, rendering them inoperable when needed. [0005] It is known to place ceramic positive ...
