A laundry treating apparatus includes a tub configured to hold wash water, a drum rotatably supported in the tub and including a shaft disposed perpendicular with the ground, and a sub-drum detachably mounted to an inner circumferential surface of the drum and configured to wash laundry independently from the drum. An information tag is disposed in the sub-drum, the tag containing information about the laundry. A reading unit is configured to acquire the information about the laundry from the information tag. A control unit is configured to determine a washing course to be performed in the sub-drum based on the information acquired by the reading unit.

The present disclosure provides a laundry treating apparatus. In one embodiment, the apparatus includes a tub for receiving washing-water therein; a first drum rotatably disposed within the tub; a second drum disposed in the first drum so as to be attachable or detachable to or from the first drum, wherein washing of a laundry by the second drum is performed separately from washing of a laundry by the first drum; and a guide rib projected from an upper portion of a inner circumferential face of the second drum toward a center of the second drum, wherein the guide rib is constructed to guide wash-water rising up via a rotational force of the second drum to flow toward a center of the second drum and then to fall down.

A laundry appliance includes an outer cabinet having a top panel that defines an aperture for accessing an interior of the cabinet. A tub is positioned within the outer cabinet and below the aperture. A rotating drum disposed within the tub. A pretreat basin is selectively positioned in an installed position relative to the top panel and above the drum. The pretreat basin has an outer frame and a pivoting central portion that rotationally operates within the outer frame between a sealed position defined by the pivoting central portion being in alignment with the outer frame and a rotated position defined by the pivoting central portion being rotated out of alignment with the outer frame.

A washing machine includes a first washing compartment to hold a first set of articles to be washed and a second washing compartment to holds a second set of articles to be washed, the second washing compartment having an inserted position and a removed position. A liquid flow valve is configured to connect to an external liquid source to selectively control flow of liquid from the external liquid source and into one or more of the first washing compartment and the second washing compartment. An electric motor is configured to rotate the first washing compartment, and the second washing compartment, when the second washing compartment is in the inserted position. A controller, in communication with the electric motor, determines a mass of the second set of articles and then determines, as a function of the determined mass, a volume of water to be added to the second washing compartment.

A washing machine includes a drum rotated about a vertical axis, and opened at a top thereof, a ring-shaped balancer coupled to an upper end of the drum, and a container detachably coupled to the balancer to contain laundry. The container includes a container body opened at a top thereof, and containing the laundry therein, and a plurality of threads protruding from an outer surface of the container body, extending long in a vertical direction, and arranged in a circumferential direction. Each of the threads is formed such that heights from valleys to roofs are gradually increased in a direction from bottom to top. The balancer includes engagement grooves formed on a ring-shaped inner circumference thereof to engage with the plurality of threads.
