Driving unit structure of drum washing machine

Abstract

The invention relates to a combining structure between a stator and a drum used for a washing device, which can accurately decide the assemble position and can minimize the damage risk for the combining position of the drum and the stator. The roller washing machine provided by the structure comprises a plurality of dropping height parts and non-dropping height parts which are formed through a radial shape for the posterior wall surface of the drum; wherein, a combining part is respectively prominently formed at central side part for each dropping height part; the stator comprises a iron corepart with sawteeth which is reeved around the sawteeth coil; the rotor forms a motor together with the stator; a supporting convex part is arranged on the surface of one side which is bent from the dropping height part for each surface of at least one combing part for the drum and is used for supporting inner wall surface at the tail end of the separation rib under the condition of combining the stator.

Description

technical field [0001] The present invention relates to a front-loading washing machine, and more specifically, to a drive unit of a direct-connection front-loading 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...

Problems solved by technology

However, the weight of the above-mentioned stator 6 is more than 1.5kg, and the dehydration rotation speed is about 600-2000RPM in a large-capacity drum washing machine motor, due to the weight of the stator 6 and vibration during high-speed rotation, and the shaking of the rotor 5 and deformation, etc., the connection between the stator 6 and the barrel 2 is easily damaged

[0018] 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

[0019] Therefore, in order to prevent damage, it is necessary to have a barrel bracket (illustration omitted) made of metal in the conventional structure. will reduce productivity
