Abstract
The invention relates to a device () for de-icing and/or cleaning insects off a vehicle window () which is designed to perform at least a window wiping function and comprising a continuous-rotation motor () designed to drive the rotation of at least one wiper () 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, onto the window () from the said at least one wiper (), 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 () to at least descend from the high position (PH) as far as the low position (PB) with the motor () 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 using the device.
