Drive assembly of pulsator washing machine

Abstract

The invention relates to a drive assembly of a pulsator washing machine. The drive assembly comprises a mounting tray. A spindle and a shaft sleeve sleeved on the spindle are rotatably disposed on the mounting tray. A reduction electromagnetic clutch mechanism is disposed between the spindle and the shaft sleeve. A drive mechanism is disposed on the lower portion of the spindle. The reduction electromagnetic clutch mechanism is an electromagnetic clutch mechanism having a function of electromagnetic clutch planetary gear reduction. The reduction electromagnetic clutch mechanism is provided with a planetary gear component and an electromagnetic clutch component. The drive mechanism is an external rotor direct-drive motor comprising a rotor and a stator. The stator is fixedly connected to the mounting tray. The rotor is fixedly connected with the spindle. The spindle and the electromagnetic clutch and planetary gear reduction mechanism are directly driven by an external rotor motor, and accordingly defects such as complex ratchet and pawl structure, large size and low control accuracy in the prior art are broken through. Electromagnetic clutching is high in transmission efficiency, accurate in transmission and clutching control and low in noise; the whole drive assembly is light in weight, pull-in voltage and holding voltage are less demanded in electromagnetic clutching, and energy consumption is reduced effectively.

Description

technical field [0001] The invention relates to a washing machine assembly, in particular to a drive assembly of a pulsator type washing machine. Background technique [0002] Washing machine is household electrical appliance commonly used in people's daily life, and present washing machine is roughly divided into three kinds from washing form, namely: drum type, agitator type and pulsator type. The pulsator washing machine relies on the positive and negative rotation of the pulsator installed at the bottom of the washing tub to drive the clothes to turn up, down, left, and right continuously, so that the clothes, between the clothes and the wall of the barrel, are gently washed in the water. Friction, decontamination and cleaning are achieved under the action of detergent. The main working conditions of the pulsator washing machine are divided into washing conditions and dehydration conditions. In the washing condition, the pulsator rotates positively and negatively at lo...

Problems solved by technology

[0004] Although adopting the electromagnetic clutch mechanism as the internal clutch of the washing machine has solved most of the shortcomings of the traditional clutch, along with years of development experience and tests on the electromagnetic clutch mechanism by the applicant, it has been found that the electromagnetic clutch mechanism still has many technical problems as the internal clutch of the washing machine , such as: large suction noise, high manufacturing cost, inconvenient processing, etc., there is still a certain distance for direct mass production
