摘要： The present disclosure relates to a laundry treatment machine. A pump motor provided in a drain pump is controlled to correspond to the operation of the main motor and the water level, so that the pump motor slows down based on the speed of rotation of the main motor and the water level and keeps operating at low speed. Therefore, the pump motor is able to keep operating without stopping operation, and the amount of noise caused by the start-up of the motor is reduced, and the time taken to align the rotor of the motor in position is reduced, thereby reducing drainage time and improving the drainage performance of the drain pump.

摘要： The present disclosure relates to a circulation pump driving apparatus and a laundry treatment machine. A circulation pump driving apparatus and a laundry treatment machine according to an embodiment of the present disclosure includes an inverter converting a DC voltage from a converter into an alternating current (AC) voltage by a switching operation and outputting the converted AC voltage to a circulation pump motor, and a controller to control the circulation pump motor to operate in at least two modes among a first mode in which a speed of the circulation pump motor is constant, a second mode in which the speed of the circulation pump motor repeatedly rises and falls, and a third mode in which the speed of the circulation pump motor rises at a first rising slope and a second rising slope and then remains constant. Accordingly, it is possible to improve washing power due to circulation pumping during washing.

摘要： The present disclosure relates to a laundry treatment machine and a method for controlling the same. An increased amount of wash water during dewatering is introduced into a pump by decreasing the speed of a pump motor provided in the pump and increasing it again based on changes in the speed of the main motor during dewatering, and the wash water introduced while the speed of the pump motor is increasing is drained. Thus, the amount of noise generated during drainage may be reduced, drainage performance may be improved, and drainage time may be shortened.

摘要： The present invention relates to a laundry handling apparatus and a control method therefor, the laundry handling apparatus being provided with multiple laundry units performing laundry independently of each other. If a first laundry unit and a second laundry unit simultaneously perform laundry and if laundry is not collected after any one laundry unit has completed laundering, the laundry handling apparatus operates with added laundry time according to the laundry time of the other laundry unit, thereby preventing the laundry from creasing and being damaged, and changes the laundry time such that the first and second laundry units finish laundering at the same time, thereby having the effect of facilitating laundry collection.

摘要： The present disclosure relates to a laundry treatment machine and a method for controlling the same. A pump motor may operate according to the steps of starting up the pump motor when operating or stopping the pump motor. Upon restarting, the pump motor may be controlled to start up after being on standby until the rotor stops, and therefore the pump may run normally even in case in which the pump repeatedly stops and runs, and the drainage performance may be improved and wash water may be drained by the operation of the pump regardless of the lift level.
