ができなかった。In the conventional washing machine having the above-described drain valve opening / closing mechanism, when the spinning is interrupted by opening the upper cover or depressing the pause key during the spinning operation, the spinning motor is stopped. After a power failure, after a certain delay time set in anticipation of the time required to stop the rotation of the dehydrating motor by the brake mechanism, the drain line motor is energized to wind up the connecting line, and until the winding of the connecting line is completed. After the delay time set based on the required time, a sequence is adopted in which the dehydration motor is energized to resume dehydration. Therefore, in the case where the rotation speed of the spin-drying motor is relatively slow, such as at the beginning or end of the spin-drying operation, and the time required for the spin-drying motor to stop after the brake is applied is relatively short, the suspension is performed. Even so, the time from when the dewatering motor is cut off to when the power to the drain valve motor is started is fixedly set, so that the time until the dewatering operation is restarted could not be shortened.

Since both the brake process flag and the 7-second delay flag are "0", the drain valve motor is first turned on while the motor 7 is off (S15), and it is necessary for the drain valve motor 12 to complete winding of the connection line. When 7 seconds have elapsed (S12), a 7-second delay flag is set (S13), and the motor right drive circuit 25 is turned on (S16).
When the drain valve motor 12 is turned on, the reverse rotation prevention mechanism of the connection line is operated to fix and maintain the connection line in the winding state (S1).

The brake is applied to the motor 7 and the drain valve motor 12 is turned off (S8, S9). The process proceeds to step S3, where the reed switch 6 detects the presence or absence of rotation of the motor 7 (S3). When it is determined that the motor has stopped (S4), the brake process flag is cleared (S5),
The drain valve motor 12 is turned on (S15), and after a lapse of 7 seconds, the motor right drive circuit 25 is turned on to restart the dehydration operation as described above.
