20110061172 | METHOD FOR WASHING AND WASHING MACHINE - A method for washing laundry and a washing machine, in which balancing of the laundry load is effectively carried out. The method for washing includes supplying wash water mixed with a detergent, spinning or rinsing the laundry by rotating the washing machine drum in which the laundry is located, thereby causing the laundry to be repeatedly lifted within and then fall towards the bottom of the drum. The method further involves balancing the laundry by repeatedly accelerating and decelerating the drum. The wash water is then drained. | 03-17-2011 |
20110067185 | WASHING METHOD AND WASHING MACHINE - A washing method and a washing machine are provided. Wash water is drained from a tub prior to initiating a main spinning process, and wash water is supplied into a drum to decrease the volume of the laundry which is increased by the draining. Therefore, it is possible to effectively reduce the volume of laundry and thus to improve the mobility of the laundry. Then, a main spinning process is performed by spinning the drum at high speed. | 03-24-2011 |
