Abstract

The invention relates to the field of washing machines, in particular to a safeguarded pulsator washer transmission mechanism. At one of a drive pulley and a driven pulley is provided with an overload protection mechanism on an inner ring. The overload protection mechanism comprises a plurality of teeth, a transmission ring, ejector contacts and elastic units, wherein the teeth are circularly and fixed mounted on an output shaft of a motor and / or an input shaft of a clutch in an array form, and the ejector contacts are as many as the teeth and mounted in an inner ring of the transmission ring in a circular array manner through the elastic units. When the ejector contacts extend out, the drive pulley drives the driven pulley to rotate; when the ejector contacts bear a torque exceeding a threshold, the teeth and the ejector separate. When the weight exceeds a set threshold, the transmission mechanism automatically slips; the body weight of a 2 to 3 aged child is far higher than the threshold when the washer normally runs, safety of children is ensured, and reliability is high.

Description

technical field [0001] The invention relates to the field of washing machines, in particular to a transmission mechanism of a pulsator washing machine. Background technique [0002] Washing machines are generally divided into two categories, namely the pulsator and the drum. The pulsator washing machine includes a mechanical support system, an electrical control system, a washing and dehydration system, a transmission system, and an inlet and drainage system. In the mechanical support system, the inner cylinder and the outer cylinder are set together, and the bottom of the outer cylinder is equipped with a clutch and a motor etc., the outer cylinder is suspended on the four corners of the box by means of suspenders to reduce vibration, and the wave wheel is set at the bottom of the inner cylinder and driven by the motor through the clutch. Existing washing machines are designed to prevent children from getting hurt by mistakenly entering the inner drum. The safety measures ...
