  • Patent number: 9181649
    Abstract: 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.
