Window-washing nozzle with defrosting device, in particular for automotive vehicles

摘要

In this nozzle with defrosting device, a heating wire (2) is pulled from a connecting point (4) lying outside the nozzle opening (3) through the nozzle opening (3), the nozzle body (1) and also through the connecting hose (5), which constitutes the heated feed hose zone (Z), as far as the pump-side connecting piece (9), on the outer circumference of which a terminal (6) is provided for the power supply, the securing clip (7) serving at the same time as a second power supply terminal. The insulating layer (10) is provided in this case inside the nozzle body (1) and extends over the nozzle edge or nozzle opening (3) in order to avoid the heating wire (2) contacting the nozzle body (1). By means of this arrangement of the heating wire (2) inside the nozzle body (1) beyond the nozzle edge (3) into the open air to the connecting point (4), freezing of the nozzle hole in the switched-on state is reliably avoided and yet at least one slightly permeable zone with thawed spray water is maintained around the heating wire (2) during driving.
