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: 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 control method for a laundry treatment apparatus, which includes a first reservoir configured to hold water and defining a first opening to receive laundry therethrough, a second reservoir placed inside the first reservoir and defining a second opening, and a pulsator rotatably provided inside the second reservoir, includes supplying water to the first reservoir and performing primary washing of the first and second reservoirs by rotating at least one of the pulsator or the second reservoir. The primary washing step includes performing a first motion by rotating the pulsator to produce a water stream inside the first and second reservoirs, and performing a second motion by rotating the second reservoir to cause water to move upward along a space between an inner circumferential surface of the first reservoir and an outer circumferential surface of the second reservoir and then be introduced into the second reservoir through the second opening.

Abstract: A miniature of a washing machine for exhibition includes: a casing having an opening at an upper portion thereof; a door for opening and closing the opening; a tub fixedly installed within the casing; a drum rotatably installed within the tub; a driving motor installed at an outer side of the tub; an electric motor unit transferring rotary force of the driving motor to the drum; a tub cover installed at an upper portion of the tub and including a guide unit for guiding water, which is discharged upwardly along an inner wall surface of the tub, to the inner side of the tub when the drum is rotated; and a light emitting unit irradiating light to the interior of the tub.
