After the laundry and the detergent are put into the washing and dewatering tub 2, the partition 14 is placed below the fluid balancer 8 so as to cover the laundry from above. set. As shown in FIG. 3A, the water supply valve 10 is operated to supply water into the washing / dewatering tub 2.

At this time, if the laundry is a futon or the like that easily traps air, as water is supplied and the water level rises,
The laundry rises due to the buoyancy, and pushes up the partition 14. Since the diameter of the partition 14 is larger than the inner diameter of the fluid balancer 8, when the partition 14 reaches the lower surface of the fluid balancer 8, the partition 14 stops and the laundry does not float any more.

Thereafter, when the water supply to the set water level S1 is completed, the operation of the water supply valve 10 is stopped, and as shown in FIG. 3 (b), the washing and dewatering tub 2 is turned on during the washing water sprinkling process T1 to T2. It is driven to rotate at the rotation speed R1. As the rotation speed of the washing and dewatering tub 2 increases, the power of stirring the washing water in the washing and dewatering tub 2 increases, and the water surface in the washing and dewatering tub 2 lowers at the center as shown in FIG.
