Washing tub assembly of washing machine and washing machine

Abstract

A washing machine washing tub assembly and a washing machine. The washing machine washing tub assembly includes: a vat, a vat pulsator and a three-power clutch; a vat piercing hole is opened on the bottom wall of the vat; The coaxial PTO shafts are respectively the first PTO shaft, the second PTO shaft and the third PTO shaft from the outside to the inside. The first PTO shaft is connected to the vat, and the first PTO shaft is used to drive the vat to rotate; The second power take-off shaft passes through the vat piercing hole and connects the vat impeller. The washing tub assembly of the above-mentioned washing machine uses a three-power clutch to replace the traditional DD variable frequency motor. The three-power clutch can provide power drive through an ordinary motor. Compared with the expensive DD variable frequency motor, the cost is lower and the overall cost of the washing machine can be reduced. , so that the washing machine with the tub-in-tub function can serve the public more easily because of the lower price.

Description

technical field [0001] The invention relates to the technical field of pulsator washing machines, in particular to a washing tub assembly of a washing machine and a washing machine. Background technique [0002] At present, in order to solve the cross-contamination between clothes cleaned by traditional washing machines, there have been barrel-in-tub washing machines on the market.

Problems solved by technology

[0003] However, the existing drum-in-tub washing machine still has the following disadvantages: the existing drum-in-tub washing machine is mainly driven by a DD (direct driver, direct drive) variable frequency motor, and the DD variable frequency motor itself has a complex structure and high cost, which pushes up the The cost of the whole machine makes the price of the drum-in-tub washing machine relatively high. Due to the price factor, it is difficult for the drum-in-tub washing machine to serve the public
