  • Publication number: 20100242550
    Abstract: A drum type washing machine including a tub installed in a cabinet is disclosed. The drum type washing machine includes a drum performing washing, a motor rotating the drum, bearing housings having bearings to support a rotation shaft, a suspension connected to the bearing housings and the cabinet to mitigate vibration generated during rotation of the drum, a bracket installed to the bearing housings to form the rear side of the tub, and a gasket installed between the bracket and the tub to seal the tub and to prevent vibration from being transmitted from the bracket to the tub. Volumes of the tub and the drum can be easily increased without increasing the volume of the cabinet. Even when the volume of the washing machine is changed, only one of the tub and the bearing housings, which is not applicable to the drum type washing machine having the changed washing capacity, is selectively replaced. Thus parts can commonly used in various drum type washing machine having different volume.

  • Patent number: 7634925
    Abstract: A washing and drying machine that is capable of performing heat exchange between outside air introduced into a cabinet and the circumferential surface of a tub so as to condense air used to dry laundry. No cooling water is used to condense air used to dry the laundry. Consumption of water is reduced, and therefore, the maintenance costs of the washing and drying machine are decreased. Furthermore, no condensing duct is necessary. Consequently, flow resistance is decreased, and drying efficiency is improved. In addition, sufficient space is provided between the rear surface of the tub and the cabinet. Consequently, the volume of the drum is increased, and the washing/drying capacity of the washing and drying machine is increased.

  • Patent number: 7617705
    Abstract: A balancer of a washing machine is provided. The balancer includes a balancer ring mounted to a drum, the balancer ring having a liquid receiving space for receiving liquid, a plurality of first baffles disposed in the interior of the balancer ring, and a plurality of second baffles disposed between the first baffles such that the first and second baffles are alternately arranged, the second baffles having a height lower than that of the first baffles. When abnormal vibration is generated in the washing machine, the surge of salt water is effectively prevented by the second baffles. Consequently, further noise and vibration due to a resonance phenomenon or other abnormal vibration is minimized.
