Abstract: Washing machine control method including an outer tub and an inner tub containing clothes rotatably disposed therein. The method includes detecting an amount of dry clothes, supplying water between the outer and inner tub such that the clothes are not wetted, discharging water from the outer tub to a circulation channel and introducing water into the inner tub through the circulation channel to wet the clothes, discharging unabsorbed water collected in the outer tub to the circulation channel such that a water level in the outer tub becomes zero while detecting a flow rate of water, and determining an amount of circulation water discharged to the circulation channel based on the flow rate detected until a water level in the outer tub becomes zero and determining properties of the clothes based on the amount of circulation water and a predetermined anticipated amount of circulation water corresponding to the amount of dry clothes detected.

Abstract: A laundry treating apparatus includes a cabinet, a tub, a drum, a water supply, a drain, a rotator rotatably disposed on a bottom surface of the drum, and a controller that controls rotation of the rotator. The rotator includes a bottom portion positioned on the bottom surface, a pillar protruding from the bottom portion toward an open surface, and a blade including a plurality of blades disposed to be spaced apart from each other along a circumferential direction of the pillar. The blade extends from the bottom portion toward the open surface in an inclined direction with respect to a longitudinal direction of the pillar. The rotator performs a first rotation for generating an ascending water flow and a second rotation for generating a descending water flow. The controller controls the rotator to alternately repeat the first rotation and the second rotation.

Abstract: A washing method according to the present invention comprises: a first rotation step for rotating an inner tub; a rotating direction detecting step for detecting the rotating direction of the inner tub; and a second rotation step for starting to rotate the inner tub in the opposite direction to the rotating direction of the inner tub when the rotation of the inner tub stops in the first rotation step. When the inner tub stops over a predetermined time and then restarts, the inner tub starts to rotate in the opposite direction to the rotating direction when the inner tub stops, thereby reducing the eccentricity of the inside of the inner tub, inhibiting collisions between the inner tub and an outer tub, reducing noise during collisions, and improving the rotation performance of the inner tub.

Abstract: A laundry treating apparatus includes a tub, a drum rotatably disposed inside the tub, a rotator that is rotatably disposed on a bottom surface of the drum and includes a pillar extending inside the drum and a plurality of blades spaced apart from each other along a circumferential direction of the pillar and inclined with respect to a longitudinal direction of the pillar, a motor for driving the drum and the rotator, and a controller that controls operation of the motor. A method for controlling the apparatus includes sensing an amount of clothes in the drum, sensing a washing load of the clothes including a moisture content from water supplied into the tub, and sensing a cloth material of the clothes. When the washing load corresponds to a normal washing load in the first cloth material sensing operation, a first washing process is performed according to the washing load.
