    Abstract: Disclosed is a washing machine including an inner tub in which fabrics are accommodated, a fixing hub installed to the inner tub, a rotating shaft configured to penetrate the inner tub and the fixing hub, a sun gear installed to the rotating shaft and having a lower gear portion and an upper pulsator coupling portion, an inner pulsator coupled to the pulsator coupling portion, a plurality of planetary gears engaged with the gear portion and rotatably arranged on the fixing hub, a ring gear having an inner circumferential surface engaged with the planetary gears, a gear box coupled to the ring gear, and an outer pulsator coupled to the gear box, the outer pulsator being larger than the inner pulsator. As the inner pulsator and outer pulsator are rotated at different rates of rotation, complex 3D water stream may be created in the inner tub, resulting in enhanced washing ability.

    IPC: D06F37/20

    CPC classification number: D06F37/203

    Abstract: A vibration limiter of a washing machine is disclosed. The vibration limiter includes a housing installed at one of a cabinet and a tub, a contact plate disposed within the housing such that the contact plate comes into contact with the other of the cabinet and the tub when the tub vibrates, a spring for elastically supporting the contact plate, a rotating member rotatable by at least one of the spring and the contact plate, and an oil damper engaged with the rotating member. The oil damper complementarily acts with the spring, to effectively absorb vibration. Accordingly, it is possible to reduce the size of the spring and to secure enhanced reliability even after prolonged use.
