Abstract
A water inlet for use in an automatic washing machine includes an inlet housing mounted to direct water downwardly between a washtub and a rotatable perforate basket during fill operations. A plurality of louvers project outwardly from a sidewall of the perforate basket so that, as the perforate basket is rotated, the louvers pass through the incoming stream of water to capture a portion thereof, and sling it inwardly to form a spray directed inwardly of the perforate basket during a spray rinse operation.
