A washing machine includes: an outer tub, an inner tub, a drain pump driven by an electric current to thereby drain water from the outer tub, a motor providing a rotational force to the inner tub, and a control unit controlling the drain pump and the motor. The control unit rotates the motor to increase a rotation speed of the inner tub to a preset first target speed during a sub spin-drying cycle to remove moisture from laundry in the inner tub, measure the current of the drain pump to measure an amount of water dehydrated from the laundry, measure, based on the current being increased and then decreased to or below a preset reference current, the rotation speed of the inner tub, and change a preset rotation time of the inner tub in a main spin-drying cycle according to the measured rotation speed of the inner tub.

Washing machine and spin-drying control method for washing machine

A method for controlling a laundry treating apparatus is disclosed. The apparatus comprises a main-drum and an auxiliary-drum selectively mounted on or separated from the main-drum. The method may comprise: a main laundry quantity detection operation for detecting a laundry quantity in the main-drum via rotation of a pulsator disposed in the main-drum; and an auxiliary laundry quantity detection operation for detecting a laundry quantity in the auxiliary-drum by driving the main-drum, wherein the auxiliary laundry quantity detection operation is performed based on the main laundry quantity detected in the main laundry quantity detection operation.

Laundry treating apparatus and method for controlling the apparatus

Disclosed is a method of controlling a laundry treating apparatus comprising a tub configured to hold wash water, a drum mounted in the tub, a pulsator mounted in the drum, a sub-drum coupled to the drum, the sub-drum being configured to hold wash water, and a drive unit configured to rotate the drum and the pulsator. The method comprises a water current forming step comprising performing a basket motion and a pulsate motion and a cooling step comprising lowering the temperature of the drive unit. The basket motion is configured to form water current in the wash water held in the tub and in the sub-drum simultaneously. The pulsate motion is configured to form water current in wash water held in the drum while the pulsator is driven. A performance timing of the cooling step is preset in at least one of the wash cycle or the rinse cycle.

Garment processing device and method for controlling same

A laundry treating apparatus may include a main drum and an auxiliary drum selectively mounted on or separated from the main drum. A method for controlling the laundry apparatus may include rotating the main drum to cause a centrifugal force for discharging water from the auxiliary drum before supplying washing water into the auxiliary drum. The method may include one of washing laundry in the main drum while the auxiliary drum is separated from the main drum, washing laundry in only the auxiliary drum while the auxiliary drum is mounted on the main drum, or washing laundry simultaneously in the auxiliary drum and the main drum while the auxiliary drum is mounted on the main drum.

The washing machine includes a tub, a drum, a plurality of balancing units moving along the circumference of a front side or a rear side of the drum in order to reduce imbalance caused by concentration of laundry when the drum rotates, a vibration sensor sensing a vibration amount of the tub, and a controller moving the plurality of balancing units according to the vibration amount of the tub, measured by the vibration sensor. The controller controls a drum motor to rotate the drum at a constant rotation speed, moves the plurality of balancing units in the same rotation direction to minimize the vibration amount of the tub, measured by the vibration sensor, and thereafter moves the plurality of balancing units in different rotation directions to minimize the vibration amount of the tub, measured by the vibration sensor, thereby reducing imbalance.

Washing machine and control method thereof

The present disclosure relates to a washing machine, having an actively movable balancer, and method of controlling the same. The washing machine according to an embodiment of the present disclosure includes: a balancing unit to move along a circumference of a drum to reduce imbalance due to an unbalanced distribution of the laundry; a transmission coil provided at a tub to generate a wireless power signal and transmit power wirelessly to the balancing unit; a transmission converter to apply power at a driving frequency to the transmission coil; a voltage measurer to measure a transmission voltage, which is a voltage of the transmission coil; and a transmission controller to control the transmission converter based on the transmission voltage measured by the voltage measurer, thereby transmitting sufficient power wirelessly to the balancing unit in a short period of time.

Washing machine and method of controlling the same

The present invention relates to a washing machine, having an actively movable balancer, and method of controlling the same. The washing machine according to an embodiment of the present invention includes: a tub; a drum; a balancing unit moving along a circumference of the drum; and a transmission coil provided at the tub, and to generate a magnetic field and transmit power wirelessly to the balancing unit, wherein the balancing unit comprises: a reception coil to generate electric power from the magnetic field formed by the transmission coil; and a position sensing unit to sense the magnetic field formed by the transmission coil and to generate a position signal when the balancing unit passes through the transmission coil.

A laundry treatment apparatus including a cabinet forming an appearance of the apparatus, a drum rotatably disposed in the cabinet, a housing fixed to the drum, an accommodation space defined within the housing forming a closed loop, a balancing unit movably disposed in the accommodation space, and a housing power line provided at an inner circumferential surface of the housing to supply power to the balancing unit, wherein the balancing unit includes a unit body, a motor for moving the unit body, a brush contacting the housing power line, and a power terminal housing fixed to the unit body and having a space in which the brush is removably installed.
