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.

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.
