Abstract: A sensor unit for vehicles for detecting at least the moisture and/or the temperature on the inside of a vehicle window by a sensor is disclosed. The sensor unit is mounted adjacent to the inside of the vehicle window, the sensor unit comprises a housing within which it is partially enclosed, the housing has at least one opening in the direction of the vehicle window through which the sensor unit is pressed against the vehicle window. The sensor unit has a printed circuit board (PCB) that is pressed against the inside of the vehicle window when the sensor unit is in the mounted state, and is arranged between the sensor and the vehicle window. The PCB is a rigid-flexible PCB comprising a bend at least in a partial region, the bend of the rigid-flexible PCB being set up in such a way as to generate an elastic restoring force, which presses the rigid-flexible PCB against the vehicle window.

Abstract: A filter cleaning device for an air conditioner includes: a casing; a filter that is disposed in the casing and through which an air flow passes; a cleaning brush that is contactable with the filter surface and removes particulate matter from the filter surface; and a dust box that receives the particulate matter, and includes a housing accommodating the cleaning brush and having an opening through which the cleaning brush protrudes to contact a filter surface, a suction tool that includes an outlet in the housing to communicate with the dust box, and applies a suction force to the dust box to remove the particulate matter from the dust box; and a lid that is movable between first and second positions, and closes the opening of the housing in the second position when the suction force is applied.

Abstract: A filter cleaning device for an air conditioner, includes: a filter through which an air flow passes, the filter having a filter surface; a brush that is contactable with the filter surface, removes particulate matter from the filter surface, and has a cylindrical shape; and a motor that rotates the brush in opposite directions to each other; a first comb-shaped member engaged with the brush; and a second comb-shaped member engaged with the brush, wherein the first and second comb-shaped members each have a length direction parallel to an axis of rotation of the brush and parallel to a width direction of each of the first and second comb-shaped members, and the first and second comb-shaped members are inclined away from each other in a cross-sectional view perpendicular to the axis of rotation of the brush.

Abstract: Filter cleaning device for an air conditioner includes: a filter to be passed through by an air flow and having a filter surface defining a width and a length of the filter; a brush that spans the filter surface in a width direction of the filter and that moves along a length of the filter; and a dust box that receives particulate matter removed from the filter by the brush and that moves together with the brush along the length of the filter. The dust box is arranged below the brush in a direction of gravity, whereby the particulate matter removed from the filter by the brush falls into the dust box by gravity.
