Problems solved by technology

Although this patent adopts electromagnetic clutch to eliminate the existing problems of traditional mechanical manipulation from the outside, because the toothed clutch ring 5 cooperates with the spline between the outer ring gear 43 of the planetary wheel, the sliding connection in the up and down direction is realized so that the volume of the clutch is reduced. It is large and heavy, and the clutch requires high pull-in voltage and high pull-in voltage, and the power consumption of the coil is large. At the same time, due to the large volume and heavy weight of the clutch, the noise generated when the clutch state is switched is large, and the clutch installation Components are susceptible to wear, which seriously affects their service life

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 ...
