A washing machine includes an inner tub assembly for accommodating laundry, a pulsator rotatably provided to an inner lower portion of the inner tub assembly, a blade installed at a lower portion of the pulsator to be rotatable independently from the pulsator, the blade being configured to pump wash water to raise the wash water to an upper end of the inner tub assembly, a drive motor for providing rotational power to the pulsator and the blade, and a power transmission unit for transmitting power of the drive motor to the pulsator and the blade, respectively. The power transmission unit includes a first planetary gear module for transmitting a rotational speed of the drive motor to the pulsator by decreasing the rotational speed, and a second planetary gear module for transmitting the rotational speed of the drive motor to the blade by decreasing the rotational speed.

A clothes treating apparatus includes a cabinet defining an entrance, a drawer configured to be drawn out from the cabinet through the entrance, a tub provided in the drawer, a circular drum bottom provided in the tub, a cylindrical drum body fixed to the drum bottom, a drum positioned on an upper surface of the drum body, a driving part including a rotating shaft that rotates the drum and penetrates the tub so as to be coupled to the drum bottom, a hub that is fixed to the center-of-rotation of the drum bottom and protrudes towards a drum inlet, and a stirring part including an arm extending from the hub towards a circumferential surface of the drum body.

A washing machine includes: a vertical axis type washing tub in which laundry and a washing liquid are housed and a washing operation including a wash step is performed; and a roller rotatably provided in an inner wall portion of the washing tub in a state that a rotation axis is vertically oriented, the roller being rotated to facilitate movement of laundry, wherein a water level of the washing liquid in the washing tub is settable in a plurality of levels ranging from a minimum water level to a maximum water level, and the roller is disposed such that an entire vertical length extends over two or more water levels among the plurality of set water levels.

A washing machine which performs a washing operation by heating water, a detergent, or a wash liquid using a dielectric heating method and a method of controlling the washing machine. The washing machine may include a water supply portion which supplies a wash liquid including water and a detergent, a power supply portion which supplies alternating current (AC) power, and an electric field forming portion which forms an electric field between a first electrode portion and a second electrode portion according to the AC power to heat the supplied wash liquid.

Provided is a washing machine and control method thereof. The washing machine includes at least one magnet attached to an auxiliary wash tub detachable from a main wash tub; a switching device configured to output a detection signal when the at least one magnet approaches within a preset range to the switching device; and a controller configured to determine whether the auxiliary wash tub is installed based on whether the detection signal of the switching device is output, and control a component in the washing machine based on the determination of whether the auxiliary wash tub is installed.

A washing machine comprises an inner drum, wherein a drum bottom of the inner drum is installed with an inner drum bottom cover, and the inner drum bottom cover is in sealed connection with the drum bottom of the inner drum to form a sealed space. Such a setting avoids problems of breeding of bacteria and generation of smudge caused when washing water enters the inner drum bottom cover and is deposited in a chamber formed between the inner drum bottom cover and the drum bottom of the inner drum in a process of washing clothes by a washing machine.

A washing appliance includes a drum that is rotationally operable within the tub about a vertical rotational axis. An impeller is positioned within a lower portion of the drum and is rotationally operable about the vertical rotational axis. The impeller includes a plurality of external vanes and a plurality of channel ribs that cooperate to promote a toroidal flow of wash fluid within the drum. A filtering cap is disposed on a top portion of the impeller and has a plurality of inlets that direct the toroidal flow of the wash fluid into a filtering chamber positioned within the filtering cap. The toroidal flow of the wash fluid continues through the filtering chamber and beneath an underside of the impeller, wherein the filtering chamber separates particulate matter from the toroidal flow of the wash fluid.
