  • Patent number: 7263864
    Abstract: Method for controlling a full automatic washing machine, the method comprising a washing cycle, a rinsing cycle, and a dewatering cycle, wherein the washing or the rinsing cycle includes the step of rotating an inner tub at a high speed higher than a preset speed in one direction, thereby making a centrifugal force caused by high speed rotation of the inner tub, to push laundry against a wall of the inner tub, to enforce washing water in the inner tub to penetrate through the laundry at a speed higher than required to make the washing done, and to pump the washing water penetrated through the laundry and discharged into an outer tub upward, to recirculate to the inner tub.
    Type: Grant

  • Patent number: 7263862
    Abstract: A washing machine is provided. The washing machine includes an outer tub configured to store washing water, an inner tub rotatably mounted in the outer tub, a pulsator configured to form a water circulation for washing laundry, and a motor installed under the outer tub and configured to rotate the inner tub and the pulsator. The motor is configured to vary a rotation speed of the inner tub and the pulsator, such that the laundry is washed by a combination of modes.
