Abstract: A tub assembly in a drum-type washing machine includes a tub body having a cylindrical shape forming front and rear edge portions; a ring-type tub cover coupled with the front edge portion of the tub body; a tub back, coupled with the rear edge portion of the tub body, comprised of an outer circumference wall extending horizontally to a predetermined distance with respect to an outer circumference of a circular panel forming a recessed space, the outer circumference wall in tight contact with the rear edge portion of the tub body; and a motor assembly loaded at the recessed space. The tub assembly enables a reduction in tub size and weight, by devising a construction that obviates the need for a bracket for fixing a bearing housing to a tub back and this minimizing a rearward protrusion of the bearing housing and tub back.

Abstract: A drum-type washing machine employs a gasket water draining hose to enable used water to be discharged via the drainpipe, immediately following a washing or rinsing step. The drum-type washing machine includes a cabinet having a door; a tub for containing water, the tub having an entrance corresponding to the door of the cabinet; a gasket, connecting the door of the cabinet to the entrance of the tub, to prevent water contained in the tub from leaking outside the tub, the gasket having a first orifice provided at a bottom point thereof; a drainpipe, communicating with the tub, to discharge water contained in the tub, the drainpipe having a second orifice provided at one side thereof; and a water draining hose, communicating the first orifice with the second orifice, to discharge water via the drainpipe.

Abstract: A cement balance weight for a drum type washing machine and its manufacturing method. The balance weight includes a housing having a predetermined inner space and an opening for cement injection. The housing includes coupling features that assist coupling the balance weight with a tub.

Abstract: A method of controlling a combined washing and drying machine is provided, which decreases the time required for completing the overall process from washing to drying. The method includes steps of inputting an operational command; performing washing and rinsing steps according to the operational command; simultaneously performing a dewatering step and a first drying step after completion of the watering and rinsing steps; and performing a second drying step after completion of the dewatering step. The first drying step may include the driving of a pump, a fan, a heater, and a drum motor, while the second drying step may include the driving of a supply valve in addition to the pump, fan, heater, and drum motor.

Abstract: A method of controlling a drum-type washing machine facilitates the removal of laundry from the drum after the completion of a wash cycle, by controlling the rotational speed/direction of a drum motor so that a force is applied to the drum, thereby separating the laundry from the inner surface of the drum, which becomes adhered thereto during a dewatering step. The method includes steps performing a wash cycle by respectively completing washing, rinsing, and dewatering steps according to a wash course; controlling the driving of the motor, after completion of the dewatering step, to apply a force to the drum; stopping the driving of the motor to allow the motor to freewheel and slow to a stop; and detecting a rotational speed of the motor as the motor freewheels.

Abstract: A tub assembly in a drum-type washing machine includes a tub body having a cylindrical shape forming front and rear edge portions; a ring-type tub cover coupled with the front edge portion of the tub body; a tub back, coupled with the rear edge portion of the tub body, comprised of an outer circumference wall rising vertically to a predetermined height with respect to an outer circumference of a circular panel forming a recessed space, the outer circumference wall in tight contact with the rear edge portion of the tub body; and a motor assembly loaded at the recessed space. The tub assembly enables a reduction in tub size and weight, by devising a construction that obviates the need for a bracket for fixing a bearing housing to a tub back and this minimizing a rearward protrusion of the bearing housing and tub back.
