が設定できる。First, the configuration of a general fully automatic washing machine used in the present invention is that a rotating tub is provided in the dewatering/washing tub, and a pulsator is provided at the inner bottom of the tub, and a main motor is used to operate the rotating tub or the pulsator. By rotating the tank, washing, rinsing, and dehydrating are carried out in one tank. The main motor is connected to the rotating tank and the pulsator by a clutch mechanism, and a brake mechanism is provided to brake the rotating tank. It has a structure in which water is drained by a valve. Note that since these structures are well-known structures, drawings are omitted. The drain valve, the brake mechanism, and the clutch mechanism are shown in FIG.
As shown in FIG. 2, the motor actuator 3 is controlled by a control means 1 and a drive device 2, and is driven in conjunction with the motor actuator 3. The motor actuator 3 generates rotational force by a small AC synchronous motor 4, which is connected and disconnected by a clutch unit 5 which is connected and connected by a solenoid 6 shown in FIG. It rotates to drive the wire 10. It also has a two-stage cam switch 9 that detects that the gear reduction mechanism 7 has rotated a specified number of revolutions, and sends a signal to the control means 1 when the two-stage cam switch 9 is activated. When the first stage cam of the two-stage cam switch 9 operates, the opening degree of the drain valve is small, and the amount of drainage is small and the noise of drainage is slight. Furthermore, when the second stage cam is operated, the drain valve is fully opened and the maximum amount of water is discharged. Therefore, the amount of displacement can be set by freely designing the shape of the cam.

The control means 1 drives the solenoid 6 and the AC synchronous small motor 4 to operate the motor actuator 3. A low-noise course is achieved by stopping the drive of the AC synchronous small motor 4 when the control means 1 receives the cam operation signal of the first stage of the two-stage cam switch 9. Further, when the user selects the normal course during the daytime, this can be realized by stopping the drive of the AC synchronous small motor 4 when the control means 1 receives the signal from the two-stage cam switch 9 twice.
