The oscillating assembly (3) of the washing machine is arranged at a distance (L) from an ultrasonic receiver (8) mounted on the outer casing (1) of the machine in a position on a side of an emitter (7). The ultrasounds are reflected by the oscillating assembly (3) and are intercepted, ie. picked up by the receiver (8) with a phase angle whose variations are indicative of the displacements of the oscillating assembly (3). <IMAGE> |
