Cleaning device for cleaning a see-through area of a motor vehicle
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.
1. 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.
2. The cleaning device according to claim 1 , wherein the flow energy converter is disposed in the at least one supply line.
3. The cleaning device according to claim 1 , wherein the flow energy converter is configured to convert flow energy provided by the cleaning fluid into thermal energy by friction, the thermal energy allowing the at least one cleaning nozzle to be heated and/or de-iced.
4. The cleaning device according to claim 1 , wherein the flow energy converter is configured to convert flow energy provided by the cleaning fluid into electrical energy, which allows heat for heating and/or de-icing the at least one cleaning nozzle to be generated.
5. A roof module for forming a vehicle roof on the motor vehicle, the roof module comprising:
a panel component which at least partially forms a roof skin of the vehicle roof, the roof skin serving as an outer sealing surface of the roof module, at least one electrical and/or electronic and/or electromagnetic component configured to send and/or receive electromagnetic signals through a see-through area, and
at least one cleaning device according to claim 1 .
6. The roof module according to claim 5 , wherein at least one electrical, electronic and/or electromagnetic component comprises an antenna and/or a measuring sensor and/or a communication device and/or an illumination device and/or an environment sensor,
the environmental sensor being at least one of a lidar sensor, a radar sensor, a camera sensor, a multi-camera sensor, and an ultrasonic sensor.
7. The roof module according to claim 5 , wherein the roof module is disposed on a vehicle body of the motor vehicle as a structural unit.
8. A motor vehicle comprising:
at least one see-through area and at least one cleaning device according to claim 1 , the cleaning device being configured to clean the at least one see-through area;
and/or at least one roof module comprising a panel component which at least partially forms a roof skin of the vehicle roof, the roof skin serving as an outer sealing surface of the roof module, at least one electrical and/or electronic and/or electromagnetic component configured
to send and/or receive electromagnetic signals through a see-through area.
