A deceleration clutch for washing machine and washing machine

Abstract

The invention relates to a deceleration clutch for a washing machine.The deceleration clutch at least comprises a clutch shaft sleeve capable of sliding up and down and a shifting fork for driving the clutch shaft sleeve.The clutch shaft sleeve slides up and down to be connected with a torque shaft sleeve and a fixed shaft sleeve respectively to achieve dehydration and washing.The clutch shaft sleeve is located in a cavity of a stator of a direct drive motor.One end of the shifting fork is located in the cavity of the stator, makes contact with the clutch shaft sleeve and shifts the clutch shaft sleeve to move axially.The other end of the shifting fork is located outside the cavity of the stator.The shifting fork is driven by a driving device to move.A buffer structure is arranged between the driving device and the shifting fork and is an elastic part.Force used for compressing or stretching the elastic part is larger than force used for shifting the clutch shaft sleeve.

Description

technical field [0001] The invention relates to the field of washing machines, in particular to a deceleration clutch for washing machines and a washing machine. Background technique [0002] At present, the function of the deceleration clutch of the pulsator type washing machine is generally to drive the pulsator to reciprocate after decelerating the bidirectional rotation of the motor. The conventional deceleration clutch is mainly composed of an input shaft, an output shaft, an output shaft sleeve, an input shaft sleeve, a brake wheel, a reduction mechanism installed inside the brake wheel, and a clutch component installed on the input shaft sleeve. In washing conditions, the output shaft is required to rotate repeatedly at low speed in both directions. The output shaft sleeve and the brake wheel are integrated. The deceleration mechanism generally only plays a simple deceleration role. When the brake wheel is braked, the output shaft sleeve is also restrained. The two-w...

Problems solved by technology

[0006] However, in the washing machine with the above-mentioned deceleration clutch, the inner tub and the pulsator frequently run in opposite directions, and the moment of inertia generated by the inner tub directly acts on the overrunning clutch. quality problem

During the rotation of the inner tub, the one-way bearing will often have a reverse force, and the one-way bearing is prone to failure. At the same time, the clutch spring will be tightened during washing, resulting in damage to the clutch spring; The driving wheel is separated and connected to the reducer. The inner drum swings in the dehydration state, which directly acts on the dehydration shaft. The dehydration shaft is eccentric, causing the washing machine to vibrate and produce noise.
