Abstract
An energy efficient washing machine includes a cleansing fluid supply system, a washer basket having an agitator device for displacing the articles to be cleansed within the basket, and a closed loop water level controller coupled to the cleansing fluid supply system and to the drive system for the agitator. The fluid supply system includes a fill nozzle designed to provide a clothes-positioning spray pattern that serves to maintain the articles evenly distributed in the basket to enables the load sensing systems of the closed loop adaptive water level controller to function to accurately provide the optimal water level for cleansing. To accomplish this positioning of the articles to be cleansed, the fluid fill nozzle typically provides a fan discharge of fluid passing therethrough and is disposed at a cant angle with respect to the direction of rotation of the basket such that the fan discharge covers an area between the agitator assembly and the sidewall of the basket.
