ABSTRACT:
A washing machine includes an outer tub, an inner tub, fluid nozzle configured to spray fluid into the inner tub, a fluid pump, and a controller. The washing machine may also include a pulsator located in the inner tub for applying a force to clothing in inner tub. During a first washing cycle, the controller causes the inner tub to rotate, and the nozzle to spray fluid onto clothing in the inner tub. During the first washing cycle, a fluid level in the outer tub may be controlled so that it is lower than the inner tub. During a second washing cycle, the inner tub is held stationary, and the pulsator applies a force to clothing in the inner tub, as occurs in conventional washing machines. Because the fluid level in the washing machine can be kept quite low during the first washing cycle, less water and less detergent is required. Also, because the level of the water is kept below the rotating inner tub during the first washing cycle, less force and thus less energy are required to rotate the inner tub.
