System and method of cleaning by ultrasonic means of a surface dirty comprising a device generating ultrasonic waves

摘要

The invention relates to a system (1) for the ultrasonic cleaning of a soiled surface (M), comprising a main structure (2), a tank (4) of cleaning liquid, and an ultrasonic wave generation device (5), comprising a plurality of piezoelectric transducers (6), the active surfaces of which are attached to a plate in order to transmit the acoustic power to the cleaning liquid, a support structure (8) in which the transducers (6) are located, at least one flexible cleaning element (9a, 9b) extending from at least one edge (8a, 8b) of the support structure (8) and defining, with one or more closure elements (10a, 10b), a cavity (11) for draining the cleaning liquid, the ultrasonic waves being emitted in the cavity (11) when the piezoelectric transducers (6) come into contact with the cleaning liquid, and a device for draining the cleaning liquid in the cavity (11).
