Abstract: The present disclosure relates to a drain pump driving apparatus and a laundry treatment machine including the same. A drain pump driving apparatus according to an embodiment of the present disclosure and a laundry treatment machine including the same include: an inverter to convert an input direct current (DC) voltage into an alternating current (AC) voltage by a switching operation and to output the converted AC voltage to a drain motor; an output current detector to detect an output current flowing in the drain motor; and a controller to control the drain motor to rotate in a first direction during a first period, rotate in a second direction opposite to the first direction during a second period, and continuously rotate in the first direction when a level of the output current at rotation in the first direction is greater than a level of the output current at rotation in the second direction. Accordingly, it is possible to secure a pumping performance of the drain pump.

Abstract: 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.
