Driving unit structure of drum washing machine

Abstract

A driving part structure of a drum washing machine, including a bucket, a stator, a rotor, and ribs; the rear wall of the bucket is radially formed with a plurality of drop portions and non-drop portions, and the central side parts of each drop portion protrude to form joints part; stator which includes: a core part formed with sawtooth; a coil wound on the sawtooth; a first insulator which is respectively combined with each joint part of the sawtooth and surrounds the front of the core part, and a rear part which surrounds the core part The second insulator; the partition rib for separating the part of each joint part connected to the barrel and the part where the coil is wound on the front of the first insulator; the rotor is located outside the stator and constitutes the motor together with the stator; the support rib It forms At least one non-drop portion of the barrel, so as to support the inner wall surface of the partition rib of the stator when the stator is combined. The invention improves the assembly performance and ensures the supporting force of the stator on the barrel rear wall.

Description

technical field [0001] The invention relates to a driving part structure of a drum washing machine. Background technique [0002] Generally speaking, according to different driving methods, front-loading washing machines can be divided into the following types: the indirect connection type that indirectly transmits the driving force of the motor to the drum through the belt wound around the motor pulley and the drum pulley; the rotor of the BLDC motor A direct connection type that directly connects to the drum and directly transmits the driving force of the motor to the drum. [0003] In the method in which the driving force of the motor is not directly transmitted to the drum, but is transmitted through a belt wound around the motor pulley and the drum pulley, energy loss occurs during the driving force transmission process, and a lot of noise is generated during the power transmission process. [0004] Therefore, in order to solve the problems of the related art drum wash...

AI Technical Summary

Problems solved by technology

But in the weight of above-mentioned stator 6 just just be more than 1.5kg, and in the motor of large-capacity drum washing machine of about 600~2000RPM, because the weight of stator 6 and the vibration of rotor 5 high-speed rotation, and rotor 5 The connection between the stator 6 and the bucket 2 is easily damaged due to the shaking and deformation of the

[0017] Moreover, in a drum washing machine using a BLDC motor and connecting the stator 6 to the rear wall of the tub 2, the diameter of the stator 6 is almost parallel to the ground, so the vibration generated during the operation of the washing machine will cause the stator 6 and the tub 2 to The damage of the connection between the more serious

[0018] Therefore, in order to prevent damage, it is necessary to have a barrel bracket (not shown) made of metal in the conventional structure. thereby reducing productivity
