<p>AN UPPER COVER (26) IS PROVIDED IN AN UPPER SECTION OF AN OUTER TUB (20) FOR HOUSING A WASHING AND DEWATERING TUB (18). THE UPPER COVER (26) HAS AN UPPER INFLOW PORT (28) AND DISCHARGE PORTS (29, 29A) COMMUNICATING WITH EACH OTHER. THE OUTER TUB (20) HAS LOWER INFLOW PORTS (22, 22A) IN AN INNER PERIPHERAL SURFACE THEREOF, AND WATER CONVEY PORTIONS (23) ARE PROVIDED FOR CONNECTING THE LOWER INFLOW PORTS (22, 22A) WITH THE UPPER INFLOW PORT (28). EACH ONE OF DISCHARGE PORTS (29, 29A), THE LOWER INFLOW PORTS (22, 22A), AND THE WATER CONVEY PORTIONS (23) MAKES A SET. IN A RINSING STEP, THE WASHING AND DEWATERING TUB (18) IS ROTATED WHEN A WATER LEVEL REACHES A PREDETERMINED WATER LEVEL (A), AND RINSING WATER SUPPLIED FROM A LOWER SECTION OF THE OUTER TUB (20) THROUGH THE OF DISCHARGE PORTS (29, 29A) BY WAY OF THE WATER CONVEY PORTIONS (23) IS SPATTERED IN THE WASHING AND DEWATERING TUB (18) BY A VANE PROVIDED IN AN OUTER-PERIPHERAL BOTTOM SURFACE SECTION OF THE WASHING AND DEWATERING TUB (18). ACCORDINGLY, A CONSTANT RINSING PERFORMANCE CAN BE RELIABLY EXERTED WITH LESS WATER EVEN IF A TAP WATER PRESSURE IS LOW.</p> |
