An improved vertical axis clothes washing machine and method having wash, rinse, and spin extraction operations including a tub, an agitator, a first basket within the tub, a second basket disposed within the first basket and positioned on the agitator for movement therewith. There is also a water supply for feeding hot and cold water into the machine, electrically powered drive for operating the agitator to effect washing of the fabrics and for rotating the baskets to centrifugally extract water from the fabrics. Water is allowed to flow from the baskets into the tub and may be recirculated from the tub into the baskets during the wash and rinse operations. The improvement is a separate cycle of a continuous wash and rinse operation followed by a spin extraction operation for washing clothes in only the second basket during the combined wash and rinse operation and directed to drain and not recirculated. At the end of the continuous wash and rinse operation the fresh water flow is stopped and a centrifugal extraction operation is completed. The improved method minimizes the amount of water used, reduces the temperature of the water and clothes to minimize wrinkling during the spin operation, improves the removal of oily soil responsive to detergent concentration, and provides for the removal of "removed" soil from the basket which minimizes redeposition.
The method of washing clothes in a vertical axis clothes washing machine having a wash fill, wash, spin extraction, rinse fill, rinse, and spin extraction operations including a tub, an agitator, a first basket within the tub, water control valves for feeding hot and cold water into the machine at a first flow rate, electrically powered drive means for operating the agitator to effect washing of the fabrics and for rotating the basket and agitator in unison to centrifugally extract water from the fabrics, communication means to allow water to flow from the basket into the tub, drain means to take water from the tub and direct it to an external drain during spin extraction, the improved method including:
