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 converting a direct current (DC) voltage from a converter into an alternating current (AC) voltage based on a switching operation and to output the converted AC voltage to a drain motor; and a controller to control the motor to, when a drain channel in a drain pump is clogged, be temporarily stopped in a period during which a speed of the motor increases and then to repeatedly rotate and stop in a first direction the same as a start-up direction, and to repeatedly rotate and stop in a second direction opposite to the first direction when the drain channel is clogged even after the motor repeatedly rotates and stops in the first direction. Accordingly, when impurities are introduced into the drain pump, the impurities can be removed in a simple manner.
