Abstract: A washing machine having a wobbling device. The wobbling device causes a wobbling action of a washboard without rotating the washboard during a washing mode operation, thus effectively washing the clothes. This wobbling device includes a vertical rotary shaft rotated by a washing shaft, and an inclined rotary shaft arranged above the vertical rotary shaft. A first rotary unit couples the inclined rotary shaft to the vertical rotary shaft, thus rotating the two shafts at the same time. An upper surface of the first rotary unit forms a first sloping surface inclined at an angle of inclination. A second rotary unit rotatably receives the inclined rotary shaft therein, and is provided at its lower surface with a second sloping surface corresponding to the first sloping surface of the first rotary unit.

Abstract: A washing machine in which the poor heat-resistant laundry is sufficiently wet so that a plurality of water curtain layers are formed at the laundry, thereby preventing the laundry from being stained and damaged when the laundry contacts the steam. According to the present invention, cold water is supplied simultaneously with injection of the steam so that the real temperature of the steam contacting the surfaces of the laundry is lowered, thereby preventing the laundry from being stained and damaged when the laundry contacts the steam.

Abstract: A washing machine and a control method thereof in which laundry is washed in a state of being directly heated by steam. The washing machine includes a microcomputer for controlling the overall operation of the washing machine to wash laundry by using steam. The microcomputer controls operations of wetting laundry with a small amount of water prior to generation of steam, uniformly spraying detergent over the wet laundry, and injecting steam onto the laundry. Accordingly, it is possible to achieve a reduction in the amount of water to be used and a reduction in wash time while preventing the laundry from being stained or damaged during the wash operation using steam.

Abstract: A clothes dryer and a method of controlling the clothes dryer. The method detects conditions of clothes using a sensor, and performs at least one of: a complex drying function to perform a drying operation, a deodorizing operation, and a wrinkle removing operation; a wrinkle removing function to perform the wrinkle removing operation and the drying operation; and a drying function to perform the drying operation, according to the detected conditions of the clothes. Accordingly, the clothes dryer is capable of not only drying the clothes, but also deodorizing the clothes and removing wrinkles. Additionally, the clothes dryer is capable of detecting conditions of clothes accommodated in a chamber, and drying and deodorizing the clothes as occasion demands, thus maintaining the clothes for a long period.

Abstract: A drum washing machine that uses less wash water, reduces an amount of electricity required to heat the wash water, and reduces washing time. The drum washing machine includes a water tub to contain water therein; a rotary drum provided in the water tub so that a rotating axis of the rotary drum is inclined relative to a horizontal axis at a predetermined first angle of inclination to allow an inlet opening of the rotary drum to be directed upward and forward, with a drain hole provided on the rotary drum at a position adjacent to the inlet opening, and an internal surface of the rotary drum being inclined relative to the rotating axis of the rotary drum at a predetermined second angle of inclination so as to guide the water to the drain hole, prior to discharging the water from the rotary drum to an outside of the rotary drum through the drain hole; a drive unit to drive the rotary drum; and a water circulation unit to feed the water from the water tub into the rotary drum.

Abstract: A drum-type washing machine including a rotatable pulsator. The drum-type washing machine includes a water tub to contain water therein. A rotary drum is included in the water tub and rotating in alternating directions to hold laundry located in the rotary drum to be washed. A pulsator is rotatably mounted to a predetermined position of the rotary drum. A rotation guide unit rotates the pulsator by a rotating force of the rotary drum. The pulsator mounted to the rotary drum increases a physical force applied to laundry, thus enhancing a washing effect.
