Front loading washing machine

Abstract

In the front loading washing machine of the invention, a bearing block is embedded at the rear part of an outer tub and is prefabricated into an integral frame member by injection molding to improve the fastening effects between the outer tub and the bearing block and between the bearing block and a rotary drum shaft to reduce vibration and noises during the high-speed rotary dewatering of a rotary drum. The front loading washing machine mainly comprises a shell, wherein the inside of the shell is provided with the outer tub for storing washing water; and the rear side of the outer tub is connected and fixed with a motor for providing a driving force. The inside of the outer tub is provided with the rotary drum capable of rotating for washing. The rotary drum shaft which transmits the driving force of the motor to the rotary drum is connected with the rear part of the rotary drum and runs through the rear part of the outer tub, and the rear end of the rotary drum shaft is connected with the rotor of the motor. The rear part of the outer tub is provided with the cylindrical bearing block which is embedded in the rear part of the outer tub and is prefabricated into the integral frame member by injection molding. The inside of the bearing block is provided with a front bearing and a rear bearing for supporting the rotary drum shaft, and the front bearing and the rear bearing are both pressed into the inside of the bearing block through clearance fit.

Description

technical field [0001] The invention provides a drum washing machine. Specifically, the invention relates to or particularly relates to a washing machine in which the bearing seat supporting the drum shaft is formed into an integrated structure by injection molding of an insert and the rear part of an outer tub. Background technique [0002] The drum washing machine commonly produced and used at present includes a washing drum and a water storage outer tub, and a motor that provides a driving force is connected and fixed on the outer tub, and the driving force is forwarded to the drum through the motor rotor and the drum shaft to pass the detergent Chemical breakdown and the mechanical impact of the tumbling water stream to remove dirt from clothing. [0003] In the prior art solution, the bearing seat supporting the drum shaft is fastened from the outside to the rear of the tub by several bolts, which not only requires special positioning tooling, but also is difficult to o...

AI Technical Summary

Problems solved by technology

After a long time of use, the material of the back wall of the outer barrel is prone to embrittlement, which may easily cause the motor to be fixed or even loose, resulting in mechanical failure when the drum rotates

[0006] In addition, in the bearing seat, clearance fit is used between the roller shaft and the bearing. This kind of combined assembly structure has the disadvantages of poor fastening and low driving force transmission efficiency, and does not meet the precision requirements of high-speed rotating rollers.
