Abstract

905,514. Washing-machines. LICENTIA PATENT-VERWALTUNGS-G.m.b.H. Feb. 9, 1961, No. 4904/61. Class 138 (2). A pump 6 governed by a switch 9 intermittently dis - charges liquid from a container 2 (enclosing a washing drum 3), whilst rinsing water is being continuously supplied to the liquid container, whereby the water level varies between O and U, the switch 9 being responsive to the water level by means of a device such as a diaphragm. The switch can be included in a programme-control system and is made inoperative when the pump is used to empty the liquid container 2. The supply voltage may be maintained at the pump and switch when the machine is not in use, to prevent flooding due to a leaking water inlet valve.
