Motor vehicle windshield cleaning system to clear away ice in cold climates

摘要

Windshield wiper washer fluid is heated and delivered to the windshield through a rubber wiping element. The fluid is heated to a substantial temperature and pressure in a sealed reservoir by using heat from the engine coolant system. Alternately a tubular electrical high intensity heating element with a turbulent counter flow is used to instantly heat the fluid. The heating element is automatically electrically energized in response to fluid form through the tubular heating elements. The wiper blade (310) used has a long fluid chamber formed along its length, and is closed at one end and connected to the fluid source at the other. Several aligned slits are formed through the blade to the outlet edge to uniformly disperse the heated washing fluid downstream of the wipe direction. A second edge blade pair effectively doubles the wiping life of the blade.
