Heatable windshield washer nozzle

Abstract

A heatable windshield washer nozzle is designed for mounting on the windshield wiper of a motor vehicle. The washer nozzle has a housing with a connection adapter. This connection adapter connects to a spray water hose that is electrically heatable via cables or woven wires molded into it. The ends of the heating cables are electrically bridged across just before the end of the hose. The housing is further equipped with a chamber for receiving a nozzle body and a heating plate above the nozzle body. A cover closes the chamber. The nozzle body is a flat chip with several channels fanning outward from a central water input opening. A bar is formed on the rim of the heating plate, which completely covers the surface of the nozzle chip. This bar extends along the connection adapter, so that when the heated spray water hose is slipped onto the connection adapter, the ends 23 of the heating cables extend over the bar of the heating plate without making direct contact. The heat generated by the heating cables is transferred to the heating plate without direct contact with the bar of the heating plate, and the heating plate can transfer its heat directly to the spray water so that it is heated even to the very end of the channels.
