Laundry tub structure and washing machine

Abstract

The invention discloses a washing drum structure and a washing machine. The washing drum structure comprises a washing drum, an auxiliary washing drum, a driving device and a transmission mechanism, wherein the washing drum is internally provided with a first washing cavity; the auxiliary washing drum is accommodated in the first washing cavity and comprises a small drum body and a small drum impeller arranged at the bottom of the small drum body; the driving device is provided with a transmission shaft which extends into the first washing cavity towards the small drum body; the transmission mechanism comprises an upper clamping cylinder and a lower clamping cylinder; one of the upper clamping cylinder and the lower clamping cylinder is provided with clamping grooves; one of the upper clamping cylinder and the lower clamping cylinder is provided with clamping blocks; the clamping blocks are clamped into the clamping grooves, so that the upper clamping cylinder and the lower clamping cylinder are in transmission connection; the upper clamping cylinder is in transmission connection with the small drum impeller; a positioning structure for connecting the transmission shaft is arrangedin the lower clamping cylinder and integrally formed with the lower clamping cylinder. According to the technical scheme, on the premise of ensuring transmission, the structures of transmission components are simplified, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a washing bucket structure and a washing machine. Background technique [0002] Conventional washing machines currently have only one tub for washing, which easily causes cross-contamination when washing different types of clothes. In order to solve the cross-contamination between the clothes washed by the traditional washing machine, a non-contamination drum-in-tub washing machine has appeared. The non-pollution-in-tub washing machine adopts the 1+N clothes washing method, 1 refers to the external non-pollution large tub, and N refers to the detachable exclusive non-pollution small tub. When washing underwear, socks, infants and other clothes that need to be washed separately, use a dedicated small bucket, and use a large bucket when washing large clothes. When you need to wash the small bucket, you only need to put the small bucket into the big bucket and snap it...

AI Technical Summary

Problems solved by technology

In the structural design of a tub-in-tub washing machine, the transmission of the transmission shaft and the keg pulsator needs to be provided with a connected transmission member. The part of the transmission member used to fix the transmission shaft in the exemplary technology is generally set separately from the transmission member. Generally, there will be assembly errors in the body setting, and it is necessary to further set a screw hole on the transmission shaft through the screw joint, and then cooperate with the screw joint to realize the power transmission of the transmission shaft to the transmission member, and then the transmission member passes through It is connected with the keg pulsator to drive the keg pulsator to rotate. In this way, there are many parts of the transmission component, the structure is complicated, and the cost is high
