Abstract

A washing machine, provided with a twistable washing tub inside a perforated spin-drying tub for improving its cleaning effect, is disclosed. The twistable washing tub is repeatedly twisted and untwisted at its sidewall during a washing process, thus repeatedly compressing and releasing the laundry and improving the laundry cleaning effect. The washing machine includes an outer tub containing water therein, and a drive unit installed at a position outside the outer tub and generating rotating force. A washing tub is rotatably set within the outer tub, and is connected to the drive unit at its lower portion. This washing tub is twistable and deformable at its sidewall to compress the laundry contained therein during a rotating action of the washing tub.
