A method for controlling a washing machine is provided. The method may include determining an amount of laundry in an inner tub, setting a supply water level according to the amount of laundry determined, supplying the water into the inner tub until a water level in an outer tub reaches the supply water level set, setting a rotation speed of a pump motor according to the amount of laundry determined, operating the pump motor at the rotation speed set, and alternatively rotating a pulsator in different directions.

Method for controlling washing machine

A washing machine and a method for controlling a washing machine are provided. The method may include sensing an amount of laundry in an inner tub, configuring an operation setting based on the amount of the laundry sensed, supplying water into the inner tub and obtaining a preliminary water supply time taken for a water level within an outer tub to reach a predetermined preliminary water supply level, spraying the water from the outer tub into the inner tub through a circulation nozzle by driving a pump and obtaining a change of water level within the outer tub as the water is sprayed through the circulation nozzle, adjusting the operation setting based on the preliminary water supply time obtained and the change of water level obtained, and performing a washing operation based on the adjusted operation setting.

Washing machine and method for controlling the same

A washing machine is provided. The washing machine may include a circulation hose, a water discharge hose, and a pump configured to selectively supply water to the circulation hose and the water discharge hose. The pump may include a pump motor that is reversible and rotatable in a first direction and second direction, an impeller rotated by the pump motor, and a pump housing to provide a space in which the impeller is accommodated. The pump housing may include a supply port, a circulation water discharge port coupled to a second end of the circulation hose, and a water discharge port coupled to the water discharge hose. The water discharge outlet and the circulation water outlet may be arranged in a circumferential direction and spaced apart from each other on a ring-shaped inner surface of the pump housing.

Washing machine

A washing machine is provided. The washing machine may include a cabinet, an outer tub, an inner tub configured to receive laundry and provided in the outer tub so as to be rotatable about a substantially vertical axis, a circulation nozzle to spray water into the inner tub, a circulation hose to guide water from the outer tub to the circulation nozzle, and a pump including a pump motor having variable speeds and an impeller configured to move water from the circulation hose to the circulation nozzle as the impeller is rotated by the pump motor.

A washing machine is disclosed. The washing machine includes an outer tub that is configured to hold water. The washing machine further includes an inner tub that is located in the outer tub and that is configured to hold laundry and spin. The washing machine further includes a circulation flowpath that is configured to circulate water discharged from the outer tub. The washing machine further includes a first nozzle that is configured to jet water supplied from the circulation flowpath to the inner tub. The washing machine further includes an adjustable pump that is configured to pump water through the circulation flowpath to the first nozzle, the adjustable pump being configured to adjust flow of water to the first nozzle.

A laundry treating apparatus is provided that may include a cabinet having an introduction port for introduction of laundry and an opening that communicates with an outside of the cabinet, a tub arranged in the cabinet and provided with a tub introduction port that communicates with the introduction port, and a detergent supply module that stores a detergent and provides the stored detergent to the tub, the detergent supply module being detachably provided at the opening.

Laundry treating apparatus having a detergent supply module

A method for controlling a rinsing cycle of a washing machine is provided. The method may include a primary rinsing by supplying water into the inner tub until a water level in the outer tub becomes a preset circulating water level, wherein some of the water is supplied through a drawer in the washing machine that holds fabric softener, and a remaining amount of water is supplied by spraying the water supplied from the external water source through the direct water nozzle via a direct water supply hose, a secondary rinsing by spraying water into the inner tub through the circulating nozzle, and a third rinsing by spraying the water into the inner tub through the direct water nozzle while draining the outer tub.

Method for controlling rinsing cycle of washing machine

There is disclosed a laundry treatment apparatus including, a cabinet comprising a laundry entrance hole configured to load laundry into the cabinet, a tub provided in the cabinet and configured to store washing water therein, the tub comprising a tub hole in communication with the laundry entrance hole, a drum rotatably provided in the tub and configured to receive the laundry loaded via the tub hole, a detergent supply unit provided under the laundry entrance hole, in communication with the tub, and configured to store detergent therein, and a water supply unit configured to supply water to the detergent supply unit.

Laundry treatment apparatus

A washing machine is disclosed. The washing machine includes a pump that is configured to drain or circulate water and that comprises a motor that is configured to operate the pump. The washing machine further includes a motor driver that is configured to supply operation power to the motor. The washing machine further includes a motor controller that is configured to set a rotation speed of the motor and that is configured to supply, to the motor driver, a signal that controls the motor. The washing machine further includes a current sensor that is configured to measure a current supplied from the motor driver to the motor. The washing machine further includes a speed sensor. The washing machine further includes a water level sensor. The washing machine further includes a main controller that is configured to start or stop operation of the motor by supplying a control command.

Laundry treatment machine

A laundry treating apparatus is provided that may include a cabinet provided with an opening that communicates with an outside of the cabinet and an introduction port for introduction of laundry, a tub arranged in the cabinet to store washing water therein and provided with a tub introduction port that communicates with the introduction port, and a detergent supply module including a module door to open and close the opening, a container provided to, in, or on the module door or the cabinet to store a detergent, and a detergent pump to move the detergent stored in the container to the tub.

A laundry treating apparatus is provided. The laundry treating apparatus may include a detergent storage device positioned below an introduction port for introducing laundry into and removing laundry from a washing tub of the apparatus, a detergent dissolution device to dissolve detergent in water, and a flow path switching valve to selectively open a flow path for dissolution of the detergent and a flow path for supply of the dissolved detergent and washing water solution to the washing tub.

Detergent dissolution device for laundry treating apparatus

A laundry treating apparatus is provided that may include a cabinet provided with an introduction port for introduction of laundry, a tub arranged in the cabinet to store washing water and provided with a tub introduction port that communicates with the introduction port, a drum rotatably provided in the tub and adapted to accommodate the laundry introduced through the tub introduction port, a detergent supply module positioned at a lower portion of the introduction port to store a liquid detergent and to provide the stored liquid detergent to the tub, and a water supply device to supply washing water to the tub and to rinse the detergent supply module using the washing water supplied to the tub.
