Abstract

A vehicle surface cleaning device comprising a vehicle integrated housing including a nozzle carrier extendable from and retractable into the bodywork of a vehicle, said nozzle carrier being provided with at least one fluid nozzle, and comprising means for contactlessly heating the fluid nozzle while being in a retracted position.

First claim

What is claimed is:

1. A vehicle surface cleaning device comprising:
a vehicle integrated housing, including a nozzle carrier, the nozzle carrier being provided with at least one fluid nozzle,
wherein the at least one fluid nozzle has a nozzle body comprising an electrically conductive material which is at least one of in contact with the nozzle body or integrated into the nozzle body,

and
at least one electrical coil which is selectively energizable with alternating current power from an alternating current power supply,
wherein, when energized with the alternating current power, the electrical coil operates as an induction heater to induction heat the electrically conductive material and defrost the fluid nozzle, and
wherein at least one of
the electrical coil is positioned around the nozzle body when the nozzle body is in a retracted position, or
the electrical coil is integrated into or wound around a nozzle carrier housing of the nozzle carrier, or
the electrical coil is arranged in bodywork of the vehicle, and

wherein the nozzle body comprises a thermoplastic material which is filled with the electrically conductive material, wherein the electrically conductive material comprises ferrous particles.

2. The vehicle surface cleaning device according to claim 1 , wherein the nozzle body includes an electrically conductive heating element.

3. The vehicle surface cleaning device according to claim 2 , wherein the electrically conductive heating element is at least one of overmolded or embedded in a potting compound.

4. The vehicle surface cleaning device according to claim 2 , wherein the heating element is in a form of a metal strip extending in parallel to a nozzle duct leading into a nozzle aperture.

5. The vehicle surface cleaning device according to claim 3 , wherein the potting compound comprises epoxy resin.

6. The vehicle surface cleaning device according to claim 1 , wherein the nozzle carrier is extendable from and retractable into the bodywork of a vehicle.

7. The vehicle surface cleaning device according to claim 1 , wherein the nozzle carrier is connectable to a cleaning fluid source.

8. The vehicle surface cleaning device according to claim 1 , wherein the nozzle carrier comprises at least one extendable and retractable piston which is slidably arranged within the nozzle carrier housing and which is extendable by virtue of the pressure of the cleaning fluid.

9. The vehicle surface cleaning device according to claim 7 , wherein the electrical coil is arranged in or at a support for the nozzle carrier housing or in a casing for the cleaning device.

10. The vehicle surface cleaning system according to claim 1 , comprising a casing to be mounted in the vehicle bodywork, a cleaning fluid source, a cleaning fluid pump and a cleaning fluid circuit or a cleaning fluid conduit.

11. The vehicle surface cleaning device according to claim 2 , wherein the electrically conductive heating element comprises a steel heating element.

12. The vehicle surface cleaning device according to claim 1 , wherein the at least one of the electrical coil is positioned around the nozzle body when the nozzle body is in a retracted position, or the electrical coil is integrated into or wound around a nozzle carrier housing of the nozzle carrier, or the electrical coil is arranged in bodywork of the vehicle further comprises:
the electrical coil positioned around the nozzle body when the nozzle body is in a retracted position.

13. The vehicle surface cleaning device according to claim 1 , wherein the at least one of the electrical coil is positioned around the nozzle body when the nozzle body is in a retracted position, or the electrical coil is integrated into or wound around a nozzle carrier housing of the nozzle carrier, or the electrical coil is arranged in bodywork of the vehicle further comprises:
the electrical coil integrated into or wound around a nozzle carrier housing of the nozzle carrier.

14. The vehicle surface cleaning device according to claim 1 , wherein the at least one of the electrical coil is positioned around the nozzle body when the nozzle body is in a retracted position, or the electrical coil is integrated into or wound around a nozzle carrier housing of the nozzle carrier, or the electrical coil is arranged in bodywork of the vehicle further comprises:
the electrical coil arranged in the bodywork of the vehicle.
