Drive system of drum washing machine and drum washing machine

Abstract

The invention provides a driving system of a drum washing machine and the drum washing machine. The driving system comprises a drum shaft sleeve, an impeller shaft, a driving source, a clutch mechanism and a speed reduction mechanism, wherein the impeller shaft is rotatably arranged in the drum shaft sleeve, the driving source comprises a stator and a rotor, and an opening of the rotor is backwards fixedly connected to the rear end of the drum shaft sleeve; the clutch mechanism is controlled to be in selective transmission connection with one of the stator and the rotor; the speed reduction mechanism comprises a planet carrier assembly which is normally connected to the clutch mechanism and a planetary gear train which is in transmission connection between the impeller shaft and the rotor;when the clutch mechanism is in transmission connection with the stator, the planet carrier assembly is fixedly connected with the stator, and the rotor drives the impeller shaft to rotate together with the drum shaft sleeve at differential speeds through the planetary gear train; when the clutch mechanism is in transmission connection with the rotor, the planet carrier assembly is fixedly connected with the rotor, and the rotor drives the impeller shaft to rotate together with the drum shaft sleeve at the same speed through the planetary gear train; the rotor is directly connected with the drum shaft sleeve, the installing span of the rotor is shortened, and the integral rigidity is improved.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a driving system of a drum washing machine and a drum washing machine including the driving system of the drum washing machine. Background technique [0002] At present, the washing principle of the drum washing machine is that the motor directly or through the belt drives the drum of the washing machine to reciprocate in a circle, and the lifting ribs on the inner wall of the drum lift the clothes and shake them, and then hang them in the air and beat them for washing to achieve the purpose of cleaning the clothes. This washing method overcomes the defects of clothes entanglement and clothes wear of wave wheel washing machines, but the washing time is long, the washing efficiency is low, and the cleaning ratio is low. [0003] In order to improve the cleaning ability, some products currently use a pulsator at the bottom of the drum, so that the drum and the pulsator...
