Abstract
A cleaning device for cleaning a see-through area of a motor vehicle, the cleaning device having at least one supply line and at least one cleaning nozzle configured to be fed with a cleaning fluid via the at least one supply line. The cleaning device has a flow energy converter configured to generate electrical energy and/or heat as the cleaning fluid flows across and/or through it.
Claims8
A cleaning device for cleaning a see-through area of a motor vehicle, the cleaning device comprising:
- at least one supply line and at least one cleaning nozzle configured to be fed with a cleaning fluid via the at least one supply line,
- wherein the cleaning device comprises a flow energy converter having an impeller configured to generate electrical energy and/or heat as the cleaning fluid flows across and/or through it,
- wherein the cleaning device comprises a bypass which is in fluid communication with the at least one supply line, the flow energy converter being disposed in the bypass,
- wherein the cleaning fluid flows through the flow energy converter when at least one cleaning nozzle is blocked, and
- wherein when the least one cleaning nozzle is blocked, an increase in pressure within the supply line causes the overcoming of one of an impeller frictional force, spring force and flow geometry, thus causing the impeller to rotate.
