A washing machine includes: a casing, a tub, a drum, a cylindrical gasket connecting an input port of the casing to an opening of the tub, a pump configured to circulate water discharged from the tub; a guide pipe fixed to the gasket configured to guide water supplied from the pump, and nozzles configured to spray water from the guide pipe into the drum. The nozzles include an upper nozzle configured to spray water downward, intermediate nozzles disposed below the upper nozzle in both left and right sides and configured to spray water downward while spraying water deeper into the drum than the upper nozzle, and lower nozzles disposed above the inflow port, disposed below the intermediate nozzles in both left and right sides based on the inflow port and configured to spray water upward.

A method controls a washing machine including a drum rotatably provided in a tub that receives water, at least one nozzle spraying water into the drum, a washing motor rotating the drum, and a circulation pump circulating water within the washing machine. The method includes: controlling a rotation of the drum by operating the washing motor to rotate the drum at a first rotation speed in a first rotation direction, and to maintain a rotation of the drum at the first rotation speed in the first rotation direction so that laundry in the drum maintains contact with an inner circumferential surface of the drum; and controlling a pump speed of the circulation pump by operating a circulation pump motor in the circulation pump to accelerate and decelerate at least once while the washing motor rotates the drum at the first rotation speed in the first rotation direction.

Washing machine, and method for controlling the same

A front-loading washing machine and a control method therefor are disclosed. The control method includes: when a sensed amount of laundry in a drum is equal to or less than a preset amount, rubbing step at which the drum is rotated in both directions, wherein the rubbing step comprises: a first rotation step at which the drum is rotated in a first direction by a preset one-direction rotational angle; and a second rotation step at which the drum is rotated by the one-direction rotational angle in a second direction opposite to the first direction, and wherein the first rotation step and the second rotation step are performed alternately and repeatedly. Accordingly, it is possible to perform a washing motion which improves washing performance and reduces wear and tear of the laundry.

Washing machine and control method therefor

The present disclosure relates to a washing machine configured to rotate a cylindrical drum formed by processing a metal sheet about a horizontal axis. The drum includes a lifter, formed by processing the metal sheet, respectively provided at a plurality of points spaced along a circumferential direction, when viewed from a front side. The lifter includes a front lifter which is formed by protruding the metal sheet into the drum, and pressurized to be extended in a longitudinal direction of the drum, and a rear lifter disposed in a rear side of the front lifter. The rear lifter is disposed to form a certain phase angle with respect to the front lifter.

A washing machine includes a casing, a tub, a drum, a pump for sending water discharged from the tub, a gasket connecting an input port of the casing to an opening of the tub and having nozzles for spraying water into the drum, and a nozzle water supply pipe fixed to the gasket configured to guide water introduced through the opening into a first sub-flow and a second sub-flow. The nozzle water pipe includes first nozzle water supply ports, formed on a first flow path to which the first sub-flow is guided, for supplying the first sub-flow to any two or more nozzles among the plurality of nozzles, and second nozzle water supply ports, formed on a second flow path to which the second sub-flow is guided, for supplying the second sub-flow to other two or more nozzles among the plurality of nozzles.

A washing machine includes a casing having an input port which is formed in a front surface thereof and to which laundry is inputted; a tub which is disposed in the casing to contain fluid, and has an opening communicating with the input port; a drum which is rotatably disposed in the tub, and contains the laundry; a pump which pumps water discharged from the tub; a circulation conduit which guides the water pumped by the pump; an annular gasket which forms a channel connecting the input port and the opening of the tub, and has a plurality of nozzles for spraying water into the drum on an inner circumferential surface defining the channel; and a nozzle water supply conduit which is fixed to the gasket, and supplies the water pumped by the pump to the plurality of nozzles.

Washing machine having circulation nozzles

The laundry treating appliance according to the present disclosure may comprise a drum that receives laundry and is capable of rotating, a motor rotating the drum, a current detector detecting a current of the motor and a controller controlling the motor to accelerate rotation of the drum and obtaining a function of current change based on the current detected by the current detector during the acceleration of the drum, and determining a first motion speed based on decreasing of a first derivative of the function of current change, wherein the controller controls the motor to stop and then controls the motor to rotate in the first motion speed.
