Moreover, the water-stirring surfaces of the whole impeller present a streamline performance featuring smooth transition, with gentle motion, thereby further improving the anti-winding effect.

Description

A kind of antiwind agitation wheel for washing machine

Technical field

The utility model relates to washing machine, particularly a kind of structure of impeller of washing machine.

Background technology

Washing machine is that a kind of mechanical energy of utilizing drives the home appliance that current are washed clothes; The common automatic washing machine with impeller contains the inner impeller of washtub and washtub, and the impeller rotation produces current; The clothing stirring of in washtub, rolling reaches clean purpose.Hence one can see that, and the current of washing machine are most important to washability.

Existing automatic washing machine generally all has the function of impeller rotating, is used for producing whirlpool and the current that roll, and be intended to produce stronger current and improve clean result, but the negative effect that brings is the winding that causes clothing easily.In case clothing twines, not only clothing is difficult to wash clean, and the heavy burden of whole washing machine is seriously eccentric, and mechanical loss increases greatly, and vibration and noise also can increase thereupon; This adverse effect is especially obvious in the water smoking of automatic washing machine.

Wuxi cygnet company takes the lead in proposing " water magic square " washing machine technology in industry, utilizes various technological means to realize not twining, and wherein, the influence of impeller technology content is very big.Along with clothing material and washing machine power and intelligentized development, the impeller of water magic square is faced with the needs of upgrading equally.

The utility model content

The purpose of the utility model is in order to solve the problem that clothing twines in the existing washing machine washing described in the background technology, to invent a kind of better agitation wheel for washing machine of anti-clothing winding effect that produces current.

For reducing the generation of twining, the current that need when impeller rotates, produce have rotation and upwards roll, and can break up clothing, reach and reduce the purpose that clothing twines.

For this reason, the antiwind agitation wheel for washing machine of the utility model contains blade seat and a plurality of blade, and blade seat is discoid, and the bottom is provided with permeable hole; The blade both sides have the drying face, and the hand-deliver of two dryings is compiled in vane tip and constitutes the blade ridge; Branch angles such as said blade are arranged on the blade seat; It is characterized in that: the centre position of said blade seat, be provided with a convexity, convexity is provided with the stirring bar with the blade equal number, and every stirring bar connects corresponding blade ridge; The lines of overlooking of described blade ridge are to have the two s shapes of arc dorsad, and the side-glance shape of blade ridge is: lean on the outside of blade seat to have arc convex, lean on the central side of blade seat to have the arc concave.

Preferably: the gradient of two drying faces on each blade is different.

Preferred blade is provided with 5, being arranged on the blade seat of five equilibrium angle.

In order further to improve current control effect, the top line of described stirring bar is shaped as the indent camber line and the blade ridge is connected smoothly.

The middle part, bottom surface of preferred blade seat is recessed, and being connected of convexity on the blade seat and bottom surface is smooth connection.

The reverse side of further preferred blade seat is provided with vertically disposed reinforcement.

Also be provided with auxiliary current muscle on the bottom surface of blade seat.

The impeller of the utility model, along with energy of rotation produces the middle current that rise, the clothing that can will rotate to the washtub center is broken up, and avoids twining.The drying face of whole impeller all is streamlined, and the drying action is gentle, also can reduce clothing and twine.

Fig. 3, the lateral plan of the utility model.

The specific embodiment

Present embodiment is the optimal case of the utility model.

Like Fig. 1, blade seat 1 is discoid, and center fixation is on rotating shaft, and work is carried out in rotation.The bottom surface of whole blade seat 1 be around toward the center indent, but in the center, be provided with a convexity 2 concentric with blade seat 1, said protruding 2 diameter be about blade seat 1 diameter 1/3, the outer of level height hypsophyll bar.

Except being provided with protruding 2 middle part, on the bottom surface of blade seat 1, from middle to around the layout of dispersing 3, five branch angles such as blade layouts of five blades.On the blade seat bottom surface between blade and the blade, be provided with permeable hole 11 and auxiliary current muscle 12.

As depicted in figs. 1 and 2, the shape of blade 3 is key design contents of the utility model, blade 3 is that a cross section is the stereochemical structure of piling shape; With divergence line around the mind-set in the blade seat 1 is with reference to the center, and the both sides of blade 3 are meant the face facing to the impeller direction of rotation, and the both sides of blade 3 are drying faces 31; Two drying faces 31 of present embodiment are inclined-planes from bottom to top; Intersect at the top and form blade ridge 32, the slope of the drying face 31 of both sides is different, forms one milder domatic and that another is steeper is domatic; Situation with the corresponding rotating of difference forms different current.

On the milder drying face of blade 3, be provided with a recessed collection groove in place near protruding 2, recessed collection groove is meant that has a pit shape structure that seamlessly transits lines, is used for concentrating and blocking water flow, and water (flow) direction is exerted an influence.On the aforesaid milder drying face, dispersing direction with blade seat is the outside, in the outside of recessed collection groove, is provided with a protruding drum, and protruding drum outside gathering place is extended to the outermost edge of blade seat 1; On the simultaneously steeper drying face, from-inner-to-outer, the curved surface of corresponding aforementioned milder drying face sets gradually protruding drum, recessed collection groove, and extension place of recessed collection groove is extended to the outermost edge of blade seat 1; Like this, the upright projection lines that the curve form of two drying faces 31 has just constituted blade ridge 32 are a s type, have two camber lines dorsad, and this can obviously embody on Fig. 2.

Simultaneously; As shown in figures 1 and 3; Blade ridge 32 is not etc. high, and its side lines are not straight lines, is that concave arc line, the outside are the shape of convex arc line but lean on blade seat 1 center position; Constitute the form at " the outer peak of interior paddy ", the outside downlink of convex arc line is extended to the outermost edges of blade seat 1.On the convexity 2 that is provided with in the middle of the blade seat 1, be provided with five stirring bars 21 that protrude in protruding periphery, stirring bar 21 is that imploded arcs is linear, and smooth connection is to the blade ridge 32 of five corresponding blades 3.Convexity 2 also is smooth connection with the junction of blade seat 1.Like this, the stirring bar 21 on protruding 2 and the drying face 31 of blade 3 fuse, and become the main function components that current produce, blade 3 appear all have on a vertical direction and the rotation direction s shape curved surface, the cross section is the complex geometry body that draws shape from bottom to top in.And, in the bottom rear of blade seat 1, be provided with vertically disposed reinforcement 13, play the effect that increases whole impeller intensity.

Like Fig. 2, for just changeing, generation is to the current at center with the rotation direction of steep drying face; Like Fig. 1, Fig. 3, under the shape directs of convexity of centre 2 and blade seat 1, water (flow) direction makes progress from the center; Can effectively break up the clothing that comes together the centre, reduce the generation of twining.Because the blade of whole impeller all is smooth connection with protruding being connected, and does not have absolute rib and chamfered groove, and is better to the control ability of current, more can produce a desired effect.
