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.
