Abstract: A washing machine with a tilted tub assembly is disclosed. In the washing machine, the tub assembly is suspended and supported within an upright housing at a predetermined angle relative to the perpendicular of the housing. The tilted position of the tub assembly within the housing is stably held by damper hangers, shock absorbing units and/or elastic support units. The tilted tub assembly is convenient to users while putting or taking laundry into or out of the tub assembly. The tilted tub assembly also forms complex and active water currents suitable for preventing laundry from being entangled during a washing operation. The washing effect of the washing machine is thus improved with a reduced deviation of the washing effect. The washing machine almost completely prevents its drive motor from being overloaded and conserves the operational time while washing laundry. This saves water and electric power during a washing operation.
