Two-impeller three-power washing machine and control method thereof

Abstract

The invention belongs to the field of a washing machine, and particularly relates to a two-impeller three-power washing machine and a control method thereof. The two-impeller three-power washing machine comprises an outer tub, an inner tub, a main impeller, an auxiliary impeller and a three-power speed reducing clutch, wherein the main impeller and the auxiliary impeller are located at the bottom of the inner tub; the auxiliary impeller is located above the center of the main impeller; the inner tub, the main impeller and the auxiliary impeller are concentrically mounted on a power rotation shaft of the three-power speed reducing clutch; the outer edge of the main impeller uplifts along the bottom of the wall of the inner tub; the longitudinal section from any point on the outer edge of the main impeller to the center of the impeller is of an L-shaped structure in arc transition; and the auxiliary impeller is of a basin-shaped structure with an uplifted outer edge. The two-impeller three-power washing machine has the characteristics of high cleaning rate, high washing uniformity and the like.

Description

technical field [0001] The invention belongs to the field of washing machines, and in particular relates to a washing machine with double pulsators and three powers and a control method thereof. Background technique [0002] With the advancement of washing machine technology, there are more and more types and styles of washing machines, including agitator washing machines, pulsator washing machines and drum-type washing machines. Among them, pulsator washing machines include ordinary double-tub washing machines and single-wheel fully automatic washing machines. , double-power washing machines and three-power washing machines. Most of the existing washing machines are washed by a single pulsator, or a single pulsator and an inner tub, or an annular large pulsator, a raised small pulsator, and an inner tub to rotate to generate washing water. For example, the utility model patent with the application number CN200420099254.5 discloses a double pulsator type automatic washing m...

AI Technical Summary

Problems solved by technology

When washing clothes, relying on the forward and reverse rotation of the pulsator or the simultaneous rotation of the pulsator and the inner tub in the opposite direction, driving the water and clothes in the tub to rotate to achieve washing. This kind of washing machine rotates by a single pulsator or a single pulsator and the inner tub For washing, the washing form is single, the water flow intensity is weak, and the washing ratio is not high; as an improvement plan, a three-power washing machine with concentric installation of large and small pulsators has appeared, relying on the inner tub, large pulsator, and small pulsator to rotate in reverse to generate rotating water flow Laundry, although this method increases the complexity of the washing water flow, but because the small wave wheel of this washing machine is mostly in the middle convex shape, the water flow generated during rotation is weak and divergent, and it is difficult to transmit the rotational force to the inner tub In the upper part, when there are many clothes to be washed, the washing force of the clothes kinked in the middle is weaker, and at the same time, the lower washing degree of the clothes in the middle also affects the overall washing ratio and washing uniformity of the washing machine
