ABSTRACT:
The present invention provides a method of rinsing fabric in a washer having a wash chamber rotatable about a vertical axis. Water is added to the wash chamber while rotating the wash chamber about its vertical axis a number of revolutions sufficient to cause the fabric, rinse water and wash chamber to rotate at approximately the same speed. The wash chamber is periodically decelerated to cause the fabric and rinse water to move relative to the wash chamber due to rotational inertia of the fabric and rinse water. The fabric is caused to tumble within the wash chamber as the wash chamber decelerates by impinging the fabric on structures in the wash chamber as the fabric is moving relative to the wash chamber. A spray of rinse water is directed onto the fabric during a first period of time as the fabric is rotating with and tumbling in the wash chamber. The rinse water is then drained from the wash chamber. Finally, the rinse water is removed from the fabric by spinning and draining the wash chamber.
