  • Patent number: 10337134
    Abstract: A laundry device comprises an outer tub, an inner tub, an inner magnetic ring and an outer magnetic ring. One of the inner magnetic ring and the outer magnetic ring is directly or indirectly fixed on a bottom wall of the inner tub and positioned at the outer side of the bottom wall of the inner tub, and the other one is directly or indirectly fixed on a bottom wall of the outer tub and positioned at the inner side of the bottom wall of the outer tub. An upper end face and a lower end face of the inner magnetic ring have the same polarity as the upper end face and the lower end face of the outer magnetic ring so that a radial repulsion between the inner magnetic ring and the outer magnetic ring is used to suppress vibration of the inner tub and/or the outer tub.

  • Patent number: 10316450
    Abstract: A washing machine comprises: an outer drum; an inner drum rotatably disposed in the outer drum; and a rotation mechanism for driving the inner drum to rotate. A rotation shaft of the rotation mechanism extends upwardly from the bottom of the outer drum to a bottom wall of the inner drum to drive the inner drum to rotate. The washing machine further comprises: at least one pair of magnets including an outer ring-shaped magnet and an inner ring-shaped magnet which is disposed at a radial inner side of the outer ring-shaped magnet and opposite to the outer ring-shaped magnet. The inner ring-shaped magnet is disposed on the rotation shaft, and the outer ring-shaped magnet is disposed at the bottom wall of the inner drum or the outer drum, so that a magnetic force between them can reduce a magnitude of vibration of the inner drum or the outer drum.

  • Publication number: 20150027173
    Abstract: The invention relates to a drum baffle and a washing machine having the same. The drum baffle includes a sheath and a bottom plate. The sheath and the bottom plate form a cavity having a hollow structure. The drum baffle is made by injection molding using one or more polymer adsorption materials, which may be used as a washing medium. The cavity of the drum baffle is internally filled with solid particles. The drum baffle includes a plurality of holes defined for communicating with the cavity of the drum baffle and an inner space of the inner drum of the washing machine to allow washing water to flow through. The drum baffle assists laundry to be rolled inside the inner drum, where the drum baffle and the solid particles inside adsorb and absorb soil in the laundry so as to achieve better washing results.
