Shifting fork switching mechanism for clutch of washing machine

Abstract

The invention discloses a shifting fork switching mechanism for a clutch of a washing machine. The shifting fork switching mechanism comprises a connecting disc, a positioning disc and a torque transmission shaft sleeve, a clutch spring is arranged between the connecting disc and the positioning disc, and the clutch spring drives the connecting disc to be matched with the torque transmission shaftsleeve; the shifting fork switching mechanism further comprises a shifting fork arranged on the positioning disc in a rotating mode and a shifting fork driving device for driving the shifting fork torotate, and a boss is arranged at one end of the shifting fork and abuts against the connecting disc; the shifting fork driving device comprises a sliding block, a sliding rail and a tension spring,one end of the tension spring is fixed to a clutch shell, and the other end of the tension spring is connected with the sliding block; when the traction motor drives the sliding block to move along the sliding rail, a dewatering plane, a hand-rubbing washing plane and a common washing plane can be sequentially matched with the shifting fork, so that the shifting fork drives the connecting disc tomove to three different positions, and three different working conditions of the clutch are achieved; and therefore, a deceleration clutch can be switched among a hand-rubbing type washing mode, a common type washing mode and a dewatering mode.

Description

technical field [0001] The invention relates to the field of washing machine clutches, in particular to a shift fork switching mechanism for washing machine clutches. Background technique [0002] Existing full-automatic washing machine is mainly divided into two kinds according to different types of washing, a hand rubbing type washing method and a common type washing method. The hand-rubbing washing method means that during the washing process, the inner tub is in a free state, and when the pulsator rotates, the inner tub rotates in the opposite direction to the pulsator, realizing the washing function of simulating manual hand-washing clothes; the ordinary washing method is the washing machine In normal state, the inner tub is in the locked (braking) state, and the pulsator rotates during washing to shake the clothes and water to realize the washing function. [0003] Wherein, when the hand-rubbing type washing machine is washed, the clothes are not easily entangled, and...

AI Technical Summary

Problems solved by technology

[0003] Among them, when the hand-rubbing washing machine is washed, the clothes are not easy to be entangled, and the wear of the clothes is less, but the washing degree of the clothes is lower than that of the ordinary washing machine.

When washing with ordinary washing machines, although the washing effect is better, the clothes are easy to be entangled, and the wear of clothes will be greater than that of hand washing machines.

[0004] Among them, the deceleration clutch itself does not have the function of automatic clutch switching. It must be manipulated by an external traction motor to drive the shift fork to act on the clutch parts to make it clutch and switch between dehydration, hand washing and ordinary washing. The rotation of the fork is usually directly driven by the traction motor through the traction rope. This driving structure cannot accurately control the rotation angle of the fork, so it cannot accurately control the working conditions of switching dehydration, hand washing and ordinary washing.
