Abstract

The utility model relates to a washing machine impeller, comprising a rotary shaft 7, a rotary disk 1, and a vane 8 arranged under the rotary disk. A conical convex rib 3 and the downward concave round arc surfaces 2 of the two sides are arranged on the rotary disk. A friction rod 4 which can roll is arranged in the middle of the downward concave round arc surfaces 2. Water in/out holes 10 are evenly distributed on arc shape concaves. The upper arc shape inclined surface of the washing machine impeller and the friction rod on the inclined surface imitate the structure of a washboard. When clothes follow eddy current to rotate and sink onto the washing machine impeller, the clothes slide from a conical arc surface to the friction rod to form similar rubbing and washing action. Due to the fact that the friction rod rolls, the winding of the clothes and the washing machine impeller is reduced, and the clean degree of the clothes is increased.

Description

Agitation wheel for washing machine

Technical field

The utility model relates to the architecture advances of agitation wheel for washing machine.

Background technology

Present washing machine, for example horizontally rotate the formula washing machine, the impeller that all has a level to rotate forward or backwards, stir the generation eddy current by protruding bone rib during its work, clothing is stirred friction along with eddy current rotates and sinks on the impeller, thereby impeller shape and the shape of convex tendon and the directly influence that the distributes performance of doing washing above it, example is the wash degree of washings and wear rate etc.CN2512799Y proposes a kind of agitation wheel for washing machine, and it directly installs washing roller on convex tendon, and roller bearing has one group of blade, with the acting in conjunction of impeller lower blade current is changed, and the ejection washing is cleaned ratio to improve.Though install at the convex tendon upper surface of impeller and to have radially-arranged roller bearing and blade thereof and can increase friction and improve clean the ratio, but being the corner of upper surface blade clamping clothing and the probability of toggle, the distinct disadvantage of being brought also increases greatly, therefore do not prevent not only that clothing from twining and distortion, cause unnecessary trouble because of clamping when increasing the damage of clothing on the contrary and taking out clothing.CN2521237Y proposes a kind of agitation wheel for washing machine that has column, is to establish highly to be the column of fin 1/2nd to 1/3rd on the ripple dish beyond the impeller middle part, and density is at 1～9/centimetre ², from height and density analysis are set, it is resultful improving wash degree, but the defective that hangs clothes is colluded in same existence, thereby clothing winding and damaged probability are increased greatly, and this kind design is also undesirable.

Summary of the invention

The purpose of this utility model is at above-mentioned two kinds of existing defectives of design, design and a kind ofly can improve wash degree, can prevent really that again clothing from twining and distortion, energy-conservation, the washing machine of economizing on water.

Design of the present utility model is, agitation wheel for washing machine, comprise turning cylinder, rotating disc and be located at blade under the rotating disc, it is characterized in that establishing fixing arc fin above the rotating disc, radially fixedly set recessed arcwall face between the fin, establishing rotatable friction-bar in the middle of the concave arc surface down, paddle hole is set evenly on the arcwall face of friction-bar periphery.

Described rotating disc is the taper seat of the low arc in middle high both sides, and its peak to the height at rotating disc center is 1/3rd to 1/4th of an impeller diameter.

The horizontal sextant angle of described rotating disc upper fixed fin and rotating disc be 30 degree to 50 degree, the horizontal sextant angle of described friction-bar and rotating disc is 20～40 to spend.

The advantage of above-mentioned design is to change water (flow) direction in the wash bucket, reduces the influence of eddy current composition as far as possible.

The fixedly fin of impeller top and the blade of below are the eddy flows that produces along with direction of rotation, it washes clothing, increase friction and great role is arranged cleaning, but also be the eddy current Main Ingredients and Appearance simultaneously, produce the main strength that clothing twines, concavo-convex arc surface transition is set in that impeller is tangential, can produce the frictional force that had both increased clothing also is the resistance opposite with the eddy flow direction, be the curved circular conical surface radially to be set in addition at impeller, clothing is rotated and when sinking on the impeller with eddy current, along with the taper cambered surface glides, avoid clothing directly on impeller, to twine, the friction-bar imitation wash-board structure on the impeller on curve slope and the inclined-plane, the motion of current makes clothing form the process of washing by rubbing with the hands, the rolling of friction-bar had both increased the clothing wash degree, also reduced clothing and impeller and twined and stir wound.

Description of drawings

Fig. 1 is the utility model Facad structure figure.

Fig. 2 is the A-A cutaway view of Fig. 1.

Among the above-mentioned figure, 1 is rotating disc, and 2 are following concaved circular cambered surface, and 3 is fin, and 4 is friction-bar, and 5 is protruding pearl, and 6 is the impeller lid, and 7 is turning cylinder, and 8 is radial blade, and 9 is reinforcement, and 10 is paddle hole.

The specific embodiment

The overall structure of impeller is by shown in Figure 1.Being located at the washing machine drum bottom surface is connected with transmission device under the bucket by turning cylinder 7, turning cylinder 7 tightens up mutually with rotating disc 1, boss is the taper fin 3 that radially is provided with on the rotating disc 1, concave surface on the rotating disc 1 is an arc surface 2, replace mutually at the fin 3 of rotating disc 1 upper process and recessed arc surface 2, form tangential concavo-convex arc surface.Rotatable friction-bar 4 is set in the middle of recessed arc surface, establishes the protruding pearl 5 of two row on each face of this friction-bar, friction-bar and rotating disc 1 horizontal sextant angle are 20～40 degree, and the central shaft of friction-bar parallels a little higher than residing arcwall face with the inclined-plane that rotating disc sink.When rotating disc rotated, friction-bar 4 was followed rotation direction and is rotated.Paddle hole 10 evenly is set on the rotating disc arcwall face, and this water hole changes the flow direction or water inlet or water outlet along with the rotation of impeller.

Fig. 2 is the vertical section A-A view of impeller, and impeller is the taper seat of the low arc-shaped transition in middle high both sides as seen from Figure 2, and its peak to the height at rotating disc center is 1/3rd to 1/4th of an impeller diameter.The taper seat both sides are ups and downs arc surface 2, boss is the taper fin 3 that radially is provided with, the horizontal sextant angle of this fin and rotating disc 1 is 30～50 degree, impeller bottom is the radial blade 8 perpendicular with rotating disc 1, the distribution of the fin on this blade and the rotating disc is consistent, and by reinforcement 9 reinforcement by connection.This blade forms shoving vertically upward along with the impeller direction of rotation sweeps current and press to barrel wall, for waterfall stream one of forms, also is the power of equally distributed turnover current on the rotating disc.
