  • Publication number: 20150020552
    Abstract: A laundry treatment apparatus including a casing, an outer tub provided in the casing, an inner tub rotatably disposed in the outer tub and a pivot pivotably supported with respect to the casing. A supporting rod connected with the pivot and the outer tub to hang the outer tub in the casing. A moving member is movably provided along the supporting rod. A first connecting member connected with the moving member. A second connecting member whose position varies with respect to the first connecting member. A frictional member provided at any one of the first connecting member and the second connecting member. The moving member includes a pivot combining part provided to be combinable with the pivot to prevent the supporting rod from escaping through the other end of the moving member while the supporting rod is not connected with the outer tub.

  • Publication number: 20150020551
    Abstract: A laundry treatment apparatus in which as an outer tub vibrates, a piston and a cylinder are relatively moved. When as the outer tub vibrates, the piston and the cylinder move relative to each other and a frictional member provides a frictional force between itself and the other one to attenuate vertical vibration of the outer tub. In particular, the piston and the cylinder are prevented from being separated from each other in the laundry treatment apparatus.

  • Publication number: 20150020548
    Abstract: A laundry treatment apparatus includes a casing; an outer tub; a supporting member coupling the outer tub to the casing; and at least one horizontal vibration buffering device connecting the supporting member with a side surface of the casing. The horizontal vibration buffering device includes a casing connecting part coupled to the casing; a supporting member connecting part coupled to the supporting member, and a damper. The supporting member connecting part has a displacement relative the casing connecting part as the outer tub vibrates. The damper provides an attenuation force corresponding to the displacement of the supporting member connecting part relative the casing connecting part.

  • Publication number: 20140047870
    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.
