Device for de-icing and/or cleaning a vehicle window using a continuous-rotation motor, and corresponding continuous-rotation motor and method

Abstract

The invention relates to a device (1) for de-icing and / or cleaning insects off a vehicle window (10) which is designed to perform at least a window wiping function and comprising a continuous-rotationmotor (40) designed to drive the rotation of at least one wiper (30) to at least a first level corresponding to a first wiping speed, referred to as high wiping speed (HWS), and a second level at a second wiping speed, referred to as low wiping speed (LWS) and lower than the first, so as to perform the wiping function, and a system for spraying a specific, de-icing or insect-cleaning liquid, ontothe window (10) from the said at least one wiper (30), characterized in that the continuous-rotation motor is designed in such a way as to operate at a third speed (CS), lower than the second speed,and in that the device is configured to cause the said wiper (30) to at least descend from the high position (PH) as far as the low position (PB) with the motor (40) operating at the very slow speed (CS) and with the said spraying system activated over at least part of the said descent. The invention also relates to the continuous-rotation motor suited to the device and to a cleaning method usingthe device.

Description

technical field [0001] The technical field of the invention is that of devices for deicing and / or cleaning the windows of vehicles, in particular motor vehicles, using wipers and liquid spray devices. Background technique [0002] Motor vehicles are usually equipped with window wiping and washing systems to ensure that the windows are wiped and washed so that the driver's view is not disrupted. Such devices generally include two wipers that wipe the outer surface of the window, for example the windshield, in order to remove the water present on this surface. In recent versions, the nozzles are positioned on the hood of the vehicle or on the wipers, and the windshield washer fluid is supplied via a pump and piping system connected to the windshield washer fluid tank. [0003] Some motor vehicles are equipped with deicing systems. Deicing systems typically include conventional wipe and wash systems of the type described above, which may also be associated with deicing fluid ...
