Abstract:
PURPOSE: To surely execute the operation of a drain valve by executing an opening instruction switch and a closing instruction switch of the drain valve by a motor driving changeover switch, and setting the time spent for switch-on of both the instruction switches longer than the time spent for switching the changeover switch, in the titled device of an automatic washing machine.
CONSTITUTION: When a signal is received to a drainage signal terminal 52, a triode AC switch 50 is turned on, a neutral leaf 33 and a drainage signal leaf 35 are connected, and a motor 38 turns. As a result, a cam turns clockwise, a pin 30a moves a moving piece 29 and a moving arm 43 is moved by a tension spring 45. A lip part 42a is separated thereby and water passes through. Subsequently, when the motor 38 rotates half, the neutral leaf 33 is separated from the drainage leaf 35 and opens fully a drain valve 21 and stops. Each leaf 33-35 and a leaf cam 30b in this case are constituted so that the neural leaf 33 and one leaf 34 or 35 are separated after the other is connected. When a feed water signal line 53 receives a signal, a triode AC switch 51 is turned on and operated in reverse.
