Heatable windshield washer nozzle

Abstract

The heatable windshield washer nozzle is designed for mounting on the windshield wiper of a motor vehicle. The washer nozzle consists of a housing (1) with a connection adapter (2). This connection adapter (2) connects to a spray water hose (19) electrically heatable via cables (22) or woven wires molded into it, while the ends (23) of the heating cables (22) are electrically bridged across just before the end (24) of the hose. The housing (1) is further equipped with a chamber (5) for storing a nozzle body (6) and includes a heating plate (28) above the nozzle body (6) as well as a cover (8) for closing the chamber (5). Here the nozzle body (6) is designed as a flat chip with several channels (26) fanning outward from a central water input opening (25). In keeping with the invention, a bar (29) is formed on the rim (32) of the heating plate (28), which completely covers the surface of the nozzle chip. This bar extends into the connection adapter (2), so that when the heated spray water hose (19) is slipped onto the connection adapter (2), the ends (23) of the heating cables (22) extend over the bar (29) of the heating plate (28) without making contact. This has the advantage that the heat generated by the heating cables is transferred to the heating plate without direct contact with the bar of the heating plate, and further that the heated heating plate can transfer its heat directly to the spray water even to the very end of the channels, so that an optimal heating of the spray water is ensured.
