Title:
DRIVING SYSTEM OF DRUM WASHING MACHINE AND DRUM WASHING MACHINE
Document Type and Number:
WIPO Patent Application WO/2019/205652
Kind Code:
A1
Abstract:
Provided are a driving system of a drum washing machine and a drum washing machine. The driving system includes: a drum shaft sleeve, a pulsator shaft, a driving source, a clutch mechanism and a speed reducing mechanism, wherein the pulsator shaft is rotatably provided inside the drum shaft sleeve, the driving source comprises a stator and a rotor, and the rotor is fixedly connected to the drum shaft sleeve; the clutch mechanism is controlled such that same is optionally engaged, in a transmission manner, to one of the stator and the rotor; and the speed reducing mechanism comprises a planet carrier assembly engaged with the clutch mechanism, and a planetary gear train connected, in a transmission manner, between the pulsator shaft and the rotor. With regard to the clutch mechanism, the clutch mechanism is engaged, in a transmission manner, with the stator, the planet carrier assembly is fixedly connected to the stator, and the rotor drives the pulsator shaft and the drum shaft sleeve to operate at different speeds by the planetary gear train; alternatively, the clutch mechanism is engaged, in a transmission manner, with the rotor, the planet carrier assembly is fixedly connected to the rotor, and the rotor drives the pulsator shaft and the drum shaft sleeve to operate at the same speed by the planetary gear train; and the rotor is directly connected to the drum shaft sleeve, so that the mounting span of the rotor is reduced and the integral rigidity is improved.
