Abstract: A drum washing machine includes a tub and a drum rotatably supported in the tub and implements a control method that allows the tub to be easily cleaned. The method of controlling the washing machine includes supplying washing water during a first water supplying step to the interior of the tub while the drum is rotating at a water-supplying RPM; and executing a first wash step following completion of the first water supply step by accelerating the rotation of the drum from the water-supplying RPM to a first-wash RPM so that a circulatory flow is created in which the washing water falls from the top of opposite ends of the tub while circulating along the inner circumferential surface of the tub due to the rotational power of the drum.

Abstract: A drum washing machine implements a control method, allowing a tub of the drum washing machine to be easily cleaned. The method includes supplying washing water during a first water supplying step to the interior of the tub while a drum rotatably supported in the tub rotates at a water-supplying RPM. A first wash step is executed following completion of the first water supplying step, and includes accelerating rotation of the drum from the water-supplying RPM to a first-wash RPM to that create a circulatory flow in which the washing water falls from the top of opposite ends of the tub while circulating along the inner circumferential surface of the tub due to the rotational power of the drum. A wash draining step is started during the first wash step, and includes turning on the drain pump and controlling the amount of the washing water in the tub.

Abstract: Disclosed are a washing machine that performs a washing course by heating wash water and a control method thereof. The method may include selecting a certain washing course from a plurality of washing courses, sensing an amount of laundry received in an inner tub and determining a wash water level required for main washing of the determined amount of laundry, supplying wash water up to a wash water level for generation of steam such that a portion of the laundry is moistened, the wash water level being higher than a bottom surface of the inner tub and lower than the wash water level for main washing, heating the wash water to a first set temperature and driving a wash water heater to generate steam from the wash water, supplying additional wash water up to the wash water level for main washing, and performing a main washing cycle.

Abstract: Control of a laundry treating apparatus, in which a drum is controlled to accelerate to a first rate of rotation and then decelerate from the first rate of rotation to a second rate of rotation. A deceleration time taken for the drum having accelerated to the first rate of rotation to be decelerated to the second rate of rotation is determined and at least one of a dryness level and a percentage of water content of laundry received in the drum is determined based on the deceleration time. A determination is made as to whether the laundry in the drum includes water-filled laundry based on at least one of the dryness level and the percentage of water content of the laundry and dehydration drying of the laundry in the drum is controlled based on the determination of whether the laundry in the drum includes water-filled laundry.

Abstract: A control method for a laundry treatment apparatus, where the laundry treatment apparatus includes a first reservoir for holding water and defining a first opening for introduction of laundry, a second reservoir placed inside the first reservoir, the second reservoir being rotatable about a rotation axis perpendicular to a bottom surface of the first reservoir and defining a second opening that is positioned under the first opening, a through-hole that is defined in the second reservoir, a spray unit for spraying water to an inside of the second reservoir, and a drain unit for draining water inside the first reservoir, includes rotating the second reservoir to thereby apply force on laundry received in the second reservoir, spraying water to the inside of the second reservoir via the spray unit, and discharging the sprayed water in the second reservoir to an outside of the first reservoir via the drain unit.

Abstract: A washing machine that performs a washing course by heating wash water and a control method thereof are provided. The method includes supplying wash water up to a wash water level for generation of steam such that a portion of laundry received in an inner tub is saturated by the wash water. The wash water level may be above a bottom surface of the inner tub and below a wash water level for main washing. The method then includes heating the wash water to a first set temperature and driving a washing heater to generate steam from the wash water, and supplying the generated steam to the inner tub, and then supplying the wash water up to the wash water level for main washing, and driving the washing heater again to heat the wash water to a second set temperature, the second set temperature being lower than the first set temperature.
