A method of controlling a washing machine. The washing machine includes a tub configured to receive water, a drum rotatably disposed in the tub, a volute pump including (i) an impeller configured to rotate in one or more directions to pump water discharged from the tub and (ii) a pump housing that defines a volute-shaped passage configured to guide water pumped by the impeller, and a circulating water supply device configured to supply water discharged from an outlet port of the volute pump into the drum. The method includes: supplying water and detergent into the tub; and rotating the impeller of the volute pump in a first direction to discharge a first amount of water from the volute pump, the first amount of water being less than a second amount of water discharged from the volute pump based on the impeller being rotated in a second direction.

A vertical axis washing machine appliance includes a plurality of elongated projections disposed on a cylindrical side wall of a basket. Each elongated projection of the plurality of elongated projections has at least one hollow tube received within a respective hole of a plurality of holes of the cylindrical side wall. Each elongated projection of the plurality of elongated projections also has a wing that extends into an inner volume of the basket.

A washing machine inner drum and a washing machine. The inner drum includes a hollow cylinder-shaped inner drum body, at least one counterweight body being arranged fixedly on the inner drum body; when the inner drum body rotates, the counterweight body rotates therewith, and the centre of mass of the counterweight body is positioned on the axis of the inner drum. The washing machine includes a shell and an outer drum, the present washing machine inner drum being arranged within the outer drum. The washing machine inner drum has good damping effects, and when vibration occurs, functions quickly and reduces the vibration.

The present invention relates to an attached block structure for an inner barrel of a washing machine. The attached block structure is of a thin wall structure, which is installed on an inner wall of the inner barrel of the washing machine, a series of bulge structures (1) are arranged on one side of the thin wall structure facing interior of the inner barrel of the washing machine, and the bulge structures (1) are distributed along curves. The attached block structure for the inner barrel of the washing machine increases the rolling strength of washing water; and meanwhile, the bulge structures (1) additionally arranged on the attached block structure can not only realize a better rubbing and kneading effect on clothes, but also realize a certain three-dimensional water flow effect, thereby improving the washing cleanness, and having better user experience.

A washing machine of an embodiment includes: a washing tub in which laundry is housed and washed; and a roller rotatably provided in an inner wall portion of the washing tub, and the roller being rotated to facilitate movement of laundry, wherein the roller is detachably attached to the washing tub.

The present disclosure belongs to the field of washing machines, in particular to a washing barrel and a washing machine having the washing barrel. The washing barrel is configured to accommodate washing water. The washing barrel comprises a barrel body and a drainage channel being arranged on a side wall of the barrel body and configured to discharge washing water in the barrel body out of the barrel body during dehydrating. The drainage channel is provided with a water inlet communicated with an inside of the barrel body; and the barrel body is provided with a guiding part used to guide washing water in the barrel body into the water inlet during dehydrating. The present disclosure has the following beneficial effects: through setting the guiding part, the washing water is guided to the drainage channel and discharged through the drainage channel to realize rapid dehydration.

A laundry treatment machine may include an outer tub having an opening at a top through which laundry is inserted. The outer tub may contain wash water for washing the laundry. An inner tub may be rotatably provided inside the outer tub. A pulsator may be rotatably provided at a bottom of the inner tub to generate a current or flow of water flowing at a lower part of the inner tub. A water current generating protrusion that protrudes inward from a peripheral surface of the inner tub and extends upward from a bottom end of the inner tub may generate a current or flow of water flowing along an upper part of the inner tub.

A washing machine is provided. The washing machine includes a water tub configured to be disposed in a cabinet and to store wash water, a rotating tub configured to be rotatably installed in the water tub and to include an opening formed in an upper end portion thereof, and a driver configured to be connected to the rotating tub and to rotate the rotating tub, wherein a deviation preventer configured to prevent wash water in the rotating tub from being deviated to one side during rotation of the rotating tub is formed at an upper end portion of the rotating tub.

A method of controlling a washing machine. The washing machine includes a tub configured to receive water, a drum rotatably disposed in the tub, a volute pump including (i) an impeller configured to rotate in one or more directions to pump water discharged from the tub and (ii) a pump housing that defines a volute-shaped passage configured to guide water pumped by the impeller, and a circulating water supply device configured to supply water discharged from an outlet port of the volute pump into the drum. The method includes: supplying water and detergent into the tub; and rotating the impeller of the volute pump in a first direction to discharge a first amount of water from the volute pump, the first amount of water being less than a second amount of water discharged from the volute pump based on the impeller being rotated in a second direction.

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.
