Abstract
A low frequency vibration type washing machine has an oscillating disc suitable for both generation of an effective circulation current in the multi-phase washing medium and prevention of energy loss. The oscillating disc vertically vibrates in the multi-phase washing medium in the washing tub at different ascending and descending velocities, thus to generate an effective circulation current in the multi-phase washing medium. A plurality of perforations are formed in the oscillating disc for both reduction of the washing medium resistance and generation of the effective circulation current in the washing medium. The washing machine also has an elastic body mounted on the oscillating disc for preservation of vibration energy loss of the washing medium in the form of elastic energy. The washing tub is preferably rounded at its inner bottom corner and at its inner bottom center about the disc drive shaft penetrating the bottom center.
