摘要： 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.

摘要： Disclosed is a method for controlling a laundry treating apparatus that includes: a tub; a main drum rotatably disposed within the tub; a driver configured to drive the main drum; and an auxiliary drum disposed in the main drum configured to be attached to or be detached from the main drum. The method comprises a positioning operation for allowing a predetermined portion of the auxiliary drum to be positioned at a target position via a rotation of the auxiliary drum, wherein the positioning operation is configured such that when the predetermined portion reaches a braking-initiation position set such that the predetermined portion is positioned at the target position, a braking of the auxiliary drum is initiated, wherein the braking-initiation position is set to vary based on a magnitude of a load applied to the driver.

摘要： A laundry treating apparatus includes a tub; a first drum disposed within the tub; a second drum disposed in the first drum and configured to couple to the first drum and to perform washing separately from the first drum; and a water discharge mechanism mounted on the second drum. The water discharge mechanism includes: a seat portion extending radially inwardly from a side wall of the second drum; a water receiving hole defined in the seat portion for receiving washing water from the second drum; and a water-discharging hole defined in the side wall for discharging washing water to an outside. The water discharge mechanism is configured to selectively flow washing-water into the discharge mechanism through the water receiving hole or discharge washing-water to the outside through the water-discharging hole, based on a magnitude of centrifugal force cause by rotation of the second drum.
