Description

Technical Field

[0001] The utility model relates to a driving mechanism of a forward and reverse turning clothes rubbing washing machine. Background Art

[0002] Washing machines are one of the contemporary household items. Early first-generation double-barrel washing machines were inconvenient to use and consumed a lot of water. Fully automatic pulsator washing machines take a long time to wash clothes, cause great damage to clothes, and also consume a lot of water. Front-loading washing machines take a short time to wash clothes, save water and electricity, cause little damage to clothes, and can also control the temperature to wash clothes. However, since they only have the same-direction rolling and beating function and no reverse rubbing function, it is difficult to wash dirty clothes clean.

[0003] The patent with the authorization announcement number CN 204849368 U discloses a sandwich rubbing washing machine, including a casing, an outer rubbing barrel and an inner rubbing barrel concentrically arranged in the casing, a power device arranged at the bottom of the casing and connected to the outer rubbing barrel and the inner rubbing barrel, and a rubbing annular cavity is provided between the outer rubbing barrel and the inner rubbing barrel, and a plurality of first corrugated grooves are evenly distributed on the outer wall and the inner wall of the rubbing annular cavity. A rubbing annular cavity is formed between the outer rubbing barrel and the inner rubbing barrel, and the volume of the rubbing annular cavity is smaller than that of a traditional washing barrel, and the contact area between the clothes and the barrel wall is increased. When washing, a linear speed difference is formed between the outer rubbing barrel and the inner rubbing barrel. When rubbing clothes, both walls of the rubbing annular cavity produce a scrubbing effect, which has a strong decontamination ability and saves time. However, the rubbing speed of the clothes in this patent application cannot be reduced. Utility Model Content
