Abstract

The utility model relates to a rotary impeller of a washing machine. Main body of the washing machine is of round shape and a plurality of laminas convex from the upper surface of the main body and stretch around in radial direction from center; the utility model is characterized in that small rolling wheels that can rotate around oneself are arranged on the upper surface of the main body. Rotating shafts of the small rolling wheel are in radial direction. The small rolling wheels can be of ball shape, ellipsoid shape, spindle shape, cylinder shape or cone shape; and the wall of the small rolling wheel has convex ribs which are in axial direction and is perfect when being of petal shape, and also can has horizontal screw shape convex ribs which has axial rotating shaft. The small rolling wheels on the impeller can rotate along with the impeller when the impeller rotating, and can rotate around itself pushed by water flow, thus can scrape and knead the washing and can generate vice water flow that vertical with the surface of the impeller. Thereby, three dimensional multiple water flow can be formed and the washing can not intertwine easily thus can be washed clean.

Description

A kind of agitation wheel for washing machine

Technical field

The utility model relates to a kind of parts of washing machine, particularly a kind of agitation wheel for washing machine that can produce multiple solid current.

Background technology

The impeller of conventional wave whell laundry machine is installed on the bottom of washtub, main body is in the form of annular discs, its central protuberance, it is connected with the driving shaft of drive unit down, a plurality of blades radially extend to the periphery from the upper surface projection of main body and from the center, when impeller is back and forth rotated by its drive unit driving, promptly in washtub, produce the back and forth current of rotation, thereby washing is contained in the interior washings of washtub; Because the impeller blade radially is provided with, therefore when impeller rotates, these radial blades will produce single circumferential circulating water flow, cause the coil buckling and the winding of washings easily, not only can damage washings, also reduce clean result.

Summary of the invention

Technical problem to be solved in the utility model is how a kind of agitation wheel for washing machine that produces three-dimensional multiple current is provided, thereby reduces the winding of washings, improves wash degree.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: the main body of agitation wheel for washing machine is in the form of annular discs substantially, a plurality of blades radially extend to the periphery from the upper surface projection of main body and from the center, it is characterized in that, also be provided with the trundle that can rotate around himself rotating shaft at the upper surface of main body, and the rotating shaft of trundle is radially roughly.

The two ends of described trundle have the axle head of protrusion, insert main body in the axle bed that the corresponding position is provided with;

That described trundle can be is spherical, ellipsoid shape, spindle, cylindrical or conical;

Described trundle perisporium can have the convex tendon that roughly is axial, and is petal for good with cross-sectional, also can have horizontal helical form convex tendon, and the rotating shaft of spiral roughly is axial;

Described trundle wherein has three blades that are mutually 120 degree angles with main body with a plurality of and be spaced to good with the blade of main body, and the trundles that are mutually 120 degree angles with three rotating shafts are the best at interval.

After adopting structure of the present utility model, when impeller rotates, trundle on the impeller had both been followed impeller and had been rotated together, under the effect of current, rotate again simultaneously around himself rotating shaft, not only washings produces friction relatively, rub, but also secondary current have been produced perpendicular to the impeller surface, thereby in washtub, form three-dimensional multiple current, greatly reduce the winding degree of washings, simultaneously, though the counter-rotating that can follow impeller owing to trundle is reversed, but because effect of inertia has hysteresis slightly, constitute relative motion with washings, increased the contact area with washings, thereby improved wash degree greatly.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As Fig. 1～shown in Figure 4, be embodiment one of the present utility model, the main body 1 of agitation wheel for washing machine is in the form of annular discs substantially, and three blades 2 that are mutually 120 degree angles radially extend to the periphery from the upper surface projection of main body 1 and from the center, in the middle of adjacent vanes 1, respectively be provided with a trundle 3 that can rotate around himself rotating shaft, it is spherical that trundle 3 roughly is, and its rotating shaft is radially setting, and its two ends have the protrusion axle head 32 of one, insert main body 1 in the axle bed that the corresponding position is provided with, referring to Fig. 2, Fig. 3; Have a plurality of axial convex tendons 31 on trundle 3 perisporiums, cross-sectionally be petal, referring to Fig. 3, Fig. 4.

As Fig. 4～shown in Figure 6, be embodiment two of the present utility model, only be that with the difference of embodiment one profile of trundle 3 roughly is the ellipsoid shape.

Described trundle 3 also can be a hollow, and insert in the axle bed of main body by a fixing with it rotating shaft at its center;

Described trundle 3 can also be other possible shapes, as spindle, cylindrical, taper shape etc., as long as its rotating shaft roughly is radially;

Convex tendon 31 on described trundle 3 perisporiums might not be for axially, and slightly deviation such as the shape of similar rifle, also can have horizontal helical form convex tendon, and the rotating shaft of spiral roughly is axial;

Described trundle 3 is not limited to three among the accompanying drawing embodiment, even have only one, it also can produce positive effect.
