Static basket washing machine
A washing machine appliance, such as a consumer washing machine, includes a casing, and a tub disposed within the casing. A wash basket is received within the tub and is configured for receipt of articles to be washed. A diffuser plate defines a continuous bottom of the wash basket and includes a plurality of passages defined therethrough. An impeller system is operably configured within the tub below the diffuser plate and includes at least one impeller that is rotationally driven during a wash cycle to direct high velocity wash water through the passages with sufficient energy to move and wash articles within the wash basket.
1. A washing machine appliance, comprising:
a casing;
a tub disposed within said casing;
a wash basket received within said tub and configured for receipt of articles to be washed;
a diffuser plate that defines a continuous bottommost surface of said wash basket upon which articles to be washed are supported in said wash basket, said diffuser plate further comprising a plurality of passages defined therethrough;
an impeller system operably configured within said tub below said diffuser plate, said impeller system including at least one rotationally driven impeller disposed below said diffuser plate at a location such that substantially all wash water is directed by said impeller system upwards through said passages in said diffuser plate during a wash cycle with sufficient energy to move and wash articles within said wash basket; and
further comprising flow-directing structure disposed at a location between said diffuser plate and said impeller to block wash water from said impeller from passing through a defined group of said passages in said diffuser plate, said defined group of passages defining drains for the wash water from said wash basket.
2. The washing machine as in claim 1 , wherein said diffuser plate is stationary within said wash basket.
3. The washing machine as in claim 2 , wherein said diffuser plate is a non-removable integral component of said wash basket.
4. The washing machine as in claim 2 , wherein said diffuser plate is a removable accessory component that is placeable within said wash basket by a consumer.
5. The washing machine as in claim 1 , wherein said impeller system comprises a single said impeller.
6. The washing machine as in claim 1 , wherein said impeller system comprises a plurality of impellers.
7. The washing machine as in claim 1 , wherein said wash basket is rotationally driven relative to said impeller during certain cycles of the wash cycle.
8. The washing machine as in claim 1 , further comprising a plurality of drain holes in the circumferential side through which the wash water drains back to said impeller.
