<p>1,160,049. Washing machines. PHILIPS GLOEILAMPENFABRIEKEN N.V. 30 May, 1968 [2 June, 1967], No. 25966/68. Heading D1A. The circuit of an electric washing and spindrying machine comprises a safety switch G which in "filling position" is connected to the winding E of the water supply valve and the winding C of the drain pump and in "end of filling position" is connected to a parallel circuit comprising in parallel the washing motor winding A and heater D, the winding F of the programme motor being connected between the junction of windings E and C and the switch G in "end of filling" position. The machine is started by turning the knob of the programme device to the first position to close the main switch 1, 2 and during filling, as winding R has a high impedance and winding C has a low impedance, the programme motor will not be driven. When switch G moves to "end of filling" position, the heating element D, motor winding A and programme device F are energized, switch H reversing the motor at intervals.</p> |
