During the dehydration process, the motor is repeatedly turned on and off to drain water from the laundry little by little and spin the spinning speed. Gradually increase to a certain degree,
After performing so-called intermittent dehydration, continuous dehydration is performed, and at the end of the dehydration process, the washing and dehydrating tub is inertially operated, and when the rotation is almost stopped, the brake is applied to end the dehydration process. At this time, the time for inertial rotation of the washing / dehydrating tub was set according to each water level during washing.

った。In such a conventional fully automatic washing machine, when the amount of laundry is small with respect to the water level,
The inertial rotation of the washing and dewatering tub reduces the weight of the rotating body, which reduces the inertial force, and after a while the rotation stops and the brakes are applied to complete the dehydration process, consuming more time than necessary. Will be done. Conversely, when the amount of laundry is large relative to the water level, inertial rotation of the washing / dehydrating tub causes the weight of the rotating body to increase, and the brake is applied before the rotation of the washing / dehydrating tub stops. There was a problem that it becomes a factor that causes the vibration and noise of.

Is less than a predetermined time Tn, that is, when Ta has a small amount of laundry and a small inertial force in the washing / dehydrating tub 1, the time from turning off the motor 5 at the end of the dehydration until applying the brake is set to be short (Td1). As shown by the broken line in FIG. 3, when the time T is longer than the predetermined time Tn, that is, when a large amount of laundry is put in the washing / dewatering tub 1 and the inertial force is large, the motor at the end of dehydration is The time Td from turning off 5 to applying the brake is set long (T
d2) Do. At this time, the inertial force decreases not only when there is a small amount of laundry, but also when there is a relatively large amount of synthetic fibers. Also, with cotton fibers that tend to contain water, conversely even when the amount is small, Grows. That is, according to this method, the time Td until the delayed braking at the end of dehydration can be optimized depending on the type of fiber of the laundry.
