POWER TRANSMISSION APPARATUS AND POWER CONTROL APPARATUS OF WASHING MACHINE

摘要

A washing machine includes a power transmission apparatus and a power control apparatus. The power transmission apparatus includes a driving unit, a gear mechanism including an input shaft connected to the driving unit, a reduction assembly coupled to the input shaft to reduce its rotational speed to a preset gear ratio, a washing shaft coupled to the reduction assembly that rotates at the gear ratio, and a water removal assembly selectively connected to the driving unit in a water removal mode for independently rotating from the washing shaft, a coupling unit selectively transmitting a power of the driving unit to the water removal assembly in the water removal mode, and a brake unit selectively forcing the water removal assembly to stop in the water removal mode.
