摘要： Piezoelectric transducers are attached to the bottom wall of an upwardly open tub of austenitic stainless steel equipped with a valved inlet in a side wall near the bottom wall, a valved outlet in the bottom wall, a removable cover provided with a receptacle for washing compositions, and a vertical row of contacts on the side wall. After the washer cycle is started by pressing a button, the washer is further controlled automatically by the opening or closing of circuits between the contacts and the grounded tub through the rising or receding liquid in the tub. A safety switch on the outer tank wall is kept closed by a permanent magnet as long as the cover is in position, and the receptacle is dropped to release the washing composition upon retraction of a latch by an electromagnet on the outer face of the tub side wall.
