During the drainage of the water injection rinse, the dirt floating in the water sinks as the water level decreases and mainly reattaches to the stirring blades 6 at the inner bottom of the washing and dewatering tub 3. Since the water starts to fall evenly, the dirt adhering to the stirring blades 6 and the like can be washed out and discharged to the outside as it is.
