摘要： A method of controlling a washing machine. The washing machine includes a tub with an entry hole configured to receive laundry, a drum rotatably disposed in the tub, a ring-shaped gasket disposed along a circumference of the entry hole of the tub, a pump configured to circulate water that is discharged from the tub, and at least one circulation nozzle provided in the gasket and configured to spray the water that is circulated by the pump into the drum. The method includes: supplying water into the tub; rotating the drum; accelerating a pump speed of the pump while the drum rotates; and based on the pump speed of the pump reaching a threshold speed during the acceleration of the pump, opening a spray valve of the washing machine such that water supplied from an external water source is sprayed into the drum through a direct water nozzle.

摘要： A method of controlling a washing machine includes: sensing a laundry amount accommodated in a drum; performing water supply into the drum according to the sensed laundry amount; rotating a pump motor at a certain initial rotation speed and transferring washing water discharged from the drum to at least one nozzle for spraying water into the drum; sensing a water level in the drum; performing a re-supply of water at least once until the sensed water level reaches a set water level; and increasing the rotation speed of the pump motor whenever the re-supply of water is performed, so that as the rotation speed of the pump motor is increased, the reaching range of the water stream sprayed through the nozzle gradually expands from the lower side of the circumferential surface of the drum to the rear surface of the drum.

摘要： A laundry treating apparatus includes a cabinet, a tub provided inside the cabinet, a drum rotatably provided inside the tub to accommodate laundry, a motor directly connected to a rotation shaft of the drum, and a controller configured to control the driving of the motor according to any one of a plurality of preset drum driving motions. The controller controls the rotation of the motor to receive a physical force greater than a static frictional force acting between the laundry and the drum from an inner surface of the drum during a process in which the laundry falls to be in contact with a portion of the drum when a first motion of the plurality of drum driving motions is selected.
