摘要:
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.
