Description

A kind of agitation wheel for washing machine that has the column brush of denomination of invention

Technical field

The utility model relates to a kind of agitation wheel for washing machine, specifically, the utility model relates to a kind of agitation wheel for washing machine that has the column brush.

Background technology

CN90209946 discloses a kind of " mesh-shape hairbrush impeller ", the distributing last iliacus (2) of projection radially of described impeller upper surface, upper surface in the impeller main body covers the contour hairbrush bundle (3) of embedding, form a umbrella hairbrush face that rises and falls, sunk area between the last iliacus is opened through hole (4), distribute alternately then the distributing lower bone rib 5 of radial projection of impeller bottom with the hairbrush bundle), can be referring to accompanying drawing 3.

CN90212990 discloses a kind of " agitation wheel for washing machine of band hairbrush ", has hairbrush on the described impeller, can be referring to accompanying drawing 4.

CN90225348 discloses a kind of " being embedded with the agitation wheel for washing machine of hairbrush piece ", embed hairbrush piece (3) between the protruding iliacus (2) of described impeller, the upper surface of hairbrush piece embeds hairbrush bundle (5) and opens through hole (4), the correspondence position of impeller bottom surface and the protruding iliacus radial fin (6) that distributing can be referring to accompanying drawing 5.

But, easy attached wire bits on the hairbrush that prior art adopts, and these lines bits are difficult to remove; Defectives such as in addition, the protruded object existence of formation impeller hairbrush easily comes off, service life is short.

Summary of the invention

The purpose of this utility model is to provide a kind of agitation wheel for washing machine, has column on the described impeller, forms the form of similar " brush ", can form the process of scrubbing when described column contacts with washings.

The purpose of this utility model can be achieved in the following manner, on the impeller of washing machine, form column, described column is distributed in the surface of impeller, when washing is carried out, except traditional current washing, column described in the utility model and the sphere that forms on the column top contact with washings, scrub thereby be additionally formed.

Below be to specific descriptions of the present utility model, by describing and, can being expressly understood the utility model in conjunction with later accompanying drawing.

In the prior art, described agitation wheel for washing machine simply can be divided into high wave wheel and low muscle impeller.

So-called high wave wheel generally is meant, impeller central authorities have carefully (with the periphery on impeller chassis than) column certain altitude that raises up, washings is with the current rotation of rolling, the major part of washings centers on the upper convex portion componental movement of impeller in the process of washing.

So-called low muscle impeller generally is meant and substantially be the plate-like impeller of platform, and washings is with the current rotation of rolling, and the overwhelming majority of washings is moved above process meta that washs and impeller.

No matter be which kind of impeller, they all have the fin on chassis and the chassis, and when impeller rotated, fin drove water and forms the current that roll, rotate, and washes clothing by rubbing with the hands by water impact.

The utility model forms column on the disclosed impeller of prior art, because contacting of the fin of impeller and washings is comparatively fierce, therefore, column described in the utility model does not exist in the fin upper end, in order to avoid the damage washings.

Column described in the utility model is present on the plane of transition between the root of impeller fin;

If the transition between the fin is unconspicuous arc of boundary or shaped face, column described in the utility model top also should be preferably below 1/3 in below 1/2 of fin height.

If the transition between the fin is unconspicuous arc of boundary or shaped face, and the fin top is that at least a camber line constitutes along the line, the top of column described in the utility model should be on the fin top below 2/3 of height along the line, be preferably below 1/2.

The radius of setting impeller is R, is not provided with column in the distance of the R/4 of the center driven axis hole of distance impeller, is preferably R/3 with the interior column that is not provided with.

Column described in the utility model comprises cylinder and top sphere, and the cross section of described cylinder is circle, ellipse, polygon or gear-like limit shape; Cylinder vertically to being cylindricality, taper; If adopt the cross section of polygon or gear-like limit shape, their rib and recess all should be arc-shaped transition.

The bottom area of the hemispherical thing in top is smaller or equal to the area of cylinder upper end, and the transition of the bottom of the hemispherical thing in top and junction, cylinder upper end also should be an arc-shaped transition.

Column described in the utility model, in the relevant position of impeller, column be set to 1-9 column/centimetre ², preferably be provided with 2/centimetre ², more preferably 3/centimetre ²Described column to be provided with along corresponding circumferencial direction of impeller and radial direction be basic proportional spacing; Described column be provided with along the corresponding circumferencial direction of impeller and radial direction can be continuously and/or be interspersed (can be referring to accompanying drawing 1, B wherein partly is illustrated in circumferencial direction and radial direction is interspersed, and it is continuous distributed that A partly is illustrated in circumferencial direction and radial direction); On every square centimeter of zone that column is set, the projected area of described column should preferably less than 20%, be more preferably less than 8% less than 50% of described setting area area.

Column described in the utility model perhaps has the impeller of column brush, its column can with the impeller integrated injection molding, can certainly adopt other several different methods to be provided with, for example, on impeller, form screw, screw in the hole the screwed column of root fixing.

Because on the zone that column is set described in the utility model, a plurality of columns form similarly " brush ", therefore, for impeller described in the utility model, the utility model also claims " a kind of have the agitation wheel for washing machine that column is brushed ".

Because column described in the utility model is to distribute with proper spacing in the zone of several definite shapes on the surface of impeller, when washing, both can in the rotation of impeller, play and simulate manually, scrubbed clothing, improve the purpose of the ability of cleaning, avoided the impeller of the band hairbrush of prior art to damage washings and flimsy defective easily again.

Appended drawings 1 is the vertical view that has the agitation wheel for washing machine of column brush described in the utility model; Accompanying drawing 2 is that the A of described impeller of accompanying drawing 1 is to cross section, cutaway view; Accompanying drawing 3-5 is the agitation wheel for washing machine that has hairbrush of the prior art; Wherein, in the accompanying

drawing

1,1 is impeller, and 2 is the convex tendon on the impeller, and 3 is column, and axis hole is 4.

The specific embodiment

Referring to accompanying drawing 1, described column is crisscross arranged at circumferencial direction and radial direction, and described column is R/2 from the minimum distance of axis hole (4).

The cylinder of described column is a cylinder, and a diameter of the hemispherical thing in top is 4/5 of a cylinder.

Column be set to 3/centimetre ²

The projected area of column is 10% of a described setting area area.
