Abstract: Provided is a washing machine. The washing machine includes a tub, a drum, a pulsator, a water stream generation unit, a filter cap, and a check valve. The tub contains washing water. The drum is rotatably disposed in the tub and receiving laundry. The pulsator is rotatably disposed inside the drum and has a spouting outlet. The water stream generation unit is disposed under the pulsator and forms a water stream spouted through the spouting outlet by circulating washing water contained between the tub and the drum. The filter cap collects foreign substances floating in washing water spouted through the spouting outlet. The check valve opens the spouting outlet by the water stream formed by the water stream generation unit.

Abstract: A laundry treating apparatus includes a drum and a rotator. The rotator includes a bottom portion positioned on a bottom surface of the drum, and a pillar protruding upward from the bottom portion and having a blade disposed on an outer circumferential surface thereof. A controller controls a driver such that the rotator performs an ascending and descending motion for forming an ascending water flow or a descending water flow at least once in a washing cycle of laundry. The controller performs a method for controlling the laundry treating apparatus and controls the driver such that a rotation in one direction and a rotation in the other direction of the rotator are performed by different amounts of rotation in the ascending and descending motion.

Abstract: A laundry treatment apparatus includes an outer tub to receive wash water, a driving motor having a stator fixed to the outer tub, and a rotor rotated relative to the stator, a washing shaft rotated together with the rotor, and a rotatable spin-drying shaft spaced apart from the rotor. The laundry treatment apparatus also includes an inner tub disposed in the outer tub, a pulsator provided in the inner tub at a lower portion thereof, and a clutch assembly. The inner tub is rotated together with the spin-drying shaft and the pulsator is rotated by the washing shaft. The clutch assembly selects one of a plurality of modes including i) at least one restriction mode of restricting the spin-drying shaft to the rotor or the outer tub and ii) a free mode of not restricting the spin-drying shaft to the rotor and the outer tub.

Abstract: A laundry treatment apparatus includes a casing; an outer tub; a supporting member coupling the outer tub to the casing; and at least one horizontal vibration buffering device connecting the supporting member with a side surface of the casing. The horizontal vibration buffering device includes a casing connecting part coupled to the casing; a supporting member connecting part coupled to the supporting member, and a damper. The supporting member connecting part has a displacement relative the casing connecting part as the outer tub vibrates. The damper provides an attenuation force corresponding to the displacement of the supporting member connecting part relative the casing connecting part.
