Abstract

The invention relates to a part of a washing machine, in particular to a transmission device of the washing machine. The transmission device comprises a drive shaft, a drive shaft sleeve, a clutch, a stator component, a rotor component and a brake mechanism, wherein the drive shaft is rotatably arranged in the drive shaft sleeve; the clutch controls the rotation of the drive shaft and the drive shaft sleeve; the stator component is positioned in the rotor component; the rotor component is fixedly connected with one end of the drive shaft through a coupler; the clutch comprises a sliding pieceand an electromagnetic coil positioned outside the sliding piece; the sliding piece can be meshed with the external teeth of the drive shaft sleeve in a vertical sliding mode; a meshing part which can be meshed with the sliding piece is arranged at the joint of the rotor component and the drive shaft; the stator component is provided with a meshing part which can be meshed with the sliding piece;the brake mechanism comprises a brake plate, a brake disc and a brake disc retainer; and the brake plate is fixedly connected with the drive shaft sleeve. The transmission device has a simple and compact structure, small volume and low manufacturing cost, and is flexibly controlled.

Description

technical field [0001] The invention relates to a washing machine component, in particular to a washing machine driving device. Background technique [0002] The washing machine is a machine that removes stains attached to the laundry through chemical decomposition and mechanical impact. The main work of the washing machine is driven by the main shaft to rotate the pulsator, stirring the water flow and the rotation of the clothes to achieve the purpose of washing the clothes. Since the clothes cannot be strongly rubbed, the speed of the pulsator is generally limited to a certain extent and cannot be too fast. Due to the limitation of space, most of the existing washing machines directly drive the main shaft to drive the pulsator through the drive motor, and the purpose of reducing the internal space of the washing machine is achieved by removing the pulley drive and the mechanical transmission mechanism that drive the washing machine. If the drive motor is used to directly ...
