Abstract: A laundry treatment machine may include: a tub; a drum that is rotatably disposed in the tub; an actuator that provides power for rotating the drum; and a balancer device that is disposed at an end where the inlet hole of the drum is formed, and adjusts the center of gravity of the drum that is rotating. The balancer device may include: a main balancer that reduces vibration of the drum by moving in the opposite direction to eccentricity that is generated when the drum is rotated; a first sub-balancer of which an arrangement gap from the main balancer is adjusted in accordance with the degree of eccentricity of the drum; and a second sub-balancer of which an arrangement gap from the main balancer is adjusted in the opposite direction of the first sub-balancer with respect to the main balancer.

Abstract: A top-loading-type washing machine including a drum, a drive module for rotating the drum via a drive shaft, inner and outer pulsators placed in the drum to be rotated in opposite directions, and a gearbox connected to the drive shaft for rotating both the pulsators. The gearbox includes a sun gear rotatably connected to the drive shaft, planetary gears rotatably engaged with the sun gear, a ring gear rotatably engaged with the planetary gears, and a carrier for connecting the planetary gears so as to be rotated along with the planetary gears. The washing machine achieves excellent washing performance via rotation of the pulsators in opposite directions and variable speeds of the pulsators relative to the drum depending on the size of the laundry load.

Abstract: A main motor is rotated at a predetermined target speed to determine whether a clutch has been normally operated during switching between a spin mode and an agitation mode. A current value sensed during rotation of the main motor is compared with a predetermined reference value to determine whether the clutch is normally operated. Mode switching is performed or the clutch is re-operated based on the determination result, thereby correctly performing switching between the spin mode and the agitation mode.

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.
