Classification: CPC D  F | IPC D  F

Claim 17:
18. A drum washing machine comprising:
an outer barrel, a drum positioned inside the outer barrel and a rotating body arranged at a bottom of the drum; and
a driving system comprising:
a hollow shaft and a solid shaft rotatably arranged in the hollow shaft;
a motor comprising a stator and a rotor, wherein the rotor is fixedly connected to one end of the hollow shaft;
a clutch mechanism configured to be controlled to be selectively engaged to one of the stator and the rotor in a transmission manner; and
a speed reduction mechanism comprising:
a planetary carrier assembly engaged to the clutch mechanism; and
a planetary gear train connected between the solid shaft and the rotor in a transmission manner,

wherein in a configuration where the clutch mechanism is engaged to the stator in the transmission manner, the planetary carrier assembly is fixedly connected with the stator, and the rotor drives the solid shaft and the hollow shaft to operate at a differential speed by the planetary gear train,
wherein in a configuration where the clutch mechanism is engaged to the rotor in the transmission manner, the planetary carrier assembly is fixedly connected with the rotor, and the rotor drives the solid shaft and the hollow shaft to operate at a same speed by the planetary gear train, and
wherein the driving system is fixedly connected to a rear end face of the outer barrel, the hollow shaft and the solid shaft extend into the drum by an opening at a bottom of the outer barrel, the hollow shaft is fixedly connected with the drum, and the solid shaft is fixedly connected with the rotating body.
