Abstract
A drum washing machine includes an inner tub and a drive system coupled to the inner tub. The drive system includes a housing, a motor disposed on one side of the housing, a rotor shaft coupled to the motor and bearing-coupled to the housing, an output shaft bearing-coupled to the housing, and wherein at least part of the output shaft is disposed in the rotor shaft, a planetary gear set that a part of the planetary gear set is spline-coupled to the rotor shaft, and other part of the planetary gear set is spline-coupled to the output shaft, and an actuator moving the planetary gear set in a horizontal direction, wherein, the housing is integrally formed with the inner tub.
