Impeller of washing machine

Abstract

The invention discloses an impeller of a washing machine. The impeller comprises an upper impeller and a lower impeller, wherein the upper impeller comprises an upper impeller disk; an upper middle boss and a plurality of upper washing ribs are arranged on the upper surface of the upper impeller disk; the upper washing ribs form an S shape along the radial direction of the upper impeller disk; the upper middle boss is shaped like a circular truncated cone; convex ribs are arranged at the side of the upper middle boss and are smoothly connected with the corresponding upper washing ribs; an opening is formed in the top of the upper middle boss; the lower impeller comprises a lower impeller disk; a lower middle boss and lower washing ribs are arranged on the upper surface of the lower impeller disk; the lower washing ribs can come into contact with the lower surfaces of the upper washing ribs; a runner is defined between the lower middle boss and the lower surface of the upper middle boss; runner openings are formed in the periphery of the lower middle boss of the lower impeller disk; ring-shaped reinforcing ribs and impeller blades are arranged on the lower surface of the lower impeller disk; an impeller lining is also arranged in the innermost ring-shaped reinforcing rib; and the shape of an impeller formed by the impeller blades satisfies the following condition: when the impeller rotates forward or backward, the water formed by stirring of the impeller flows through the runner upward or downward.

Description

technical field [0001] The invention relates to the field of washing machine components, in particular to a pulsator arranged at the lower part of the inner cylinder of the washing machine and capable of forming water movement when rotating. Background technique [0002] Washing machines can generally be divided into three types: agitator type, drum type and pulsator type. [0003] There is a stirring rod and several stirring wings in the center of the inner drum of the stirring washing machine. The stirring rod and the stirring wings can rotate back and forth quickly or slowly within a 360° range according to different clothing textures, dirt degrees, and washing quality. Hold the clothes in your arms and rub them back and forth to remove stains. Agitator-type washing machines have excellent cleaning power, but are loud during the washing process, cause excessive shaking, and wear clothes more. [0004] A drum-type washing machine usually has a drum with a horizontal or i...

AI Technical Summary

Problems solved by technology

The one-way circulating water flow is not conducive to solving the problem of entanglement of clothes, and once the clothes are entangled, not only the clothes are difficult to be washed, but also the load of the whole washing machine will be seriously eccentric, the mechanical loss will be greatly increased, and the vibration and noise will also increase; this disadvantage The effect is especially pronounced in the spin phase of fully automatic washing machines
