Abstract
The utility model relates to a washer impeller with a double structure, comprising a plastic impeller and an impeller inserting member 1 which is positioned at the center of the bottom of the plastic impeller and is used for connecting the impeller and a transmission shaft. The utility model is characterized in that the plastic impeller is used as an impeller base, the surface of the plastic impeller is provided with an impeller outer sleeve made of a sheet metal. The utility model has the advantages that the surface hardness and the surface smoothness of the impeller are improved, the impeller can not be scuffed and scratched easily by washings, static electricity can not be generated easily, and thereby, scale deposit at the bottom of the impeller can be decreased; meanwhile, and the abrasion of the impeller for the washings can be decreased.
Description
The utility model relates to a kind of agitation wheel for washing machine, particularly relates to a kind of double-deck agitation wheel for washing machine that has.
Impeller of the prior art is single layer structure, and mainly adopts injection molding, requires not high to its surperficial hardness and fineness.But in fact, the impeller of pulsator washing machine is with the forward and reverse constantly of lower speed, agitator treating liquid, thereby drive the rotation that washings is made both forward and reverse directions, utilize between cleaning solution and the washings, friction between impeller and the washings, dirt on the washings is washed off, therefore, the weak point of existing impeller is after (1) uses a period of time, impeller can be subjected to certain wearing and tearing, and hard thing such as the button, slide fastener etc. that can lose in gloss, the especially clothing on surface are comparatively obvious to the damage that the skin wheel surface produces; (2) friction of plastics impeller and clothing can produce static, because the suction-operated of static makes impeller bottom incrustation easily, accumulates over a long period, incrustation may hinder the normal operation of impeller and cause impeded drainage, cleans the impeller bottom so the user generally will regularly pull down impeller; (3) effect of attrition of impeller is attractive in appearance.
It is a kind of not easy to wear that the purpose of this utility model is to provide, and reduces the generation of static, thereby reduce the double-deck agitation wheel for washing machine of impeller bottom incrustation.
The purpose of this utility model can realize by following technical measures: realize not easy to wear, will improve the hardness of material, generally can select the higher plastics of hardness, or the method that suitably increases the additive that improves hardness on raw-material basis realizes, but, being easy to generate static is the material characteristic of plastics, and the impeller material that only changes could realize reducing the purpose of static.So select the metal material substituted for plastic can realize the purpose of this utility model, but, whole impeller is made with metal, uneconomic beyond doubt (comprising the raising of material cost and processing cost), the weight of impeller is improved greatly, the series of parameters of original transmission system is made corresponding changes.Therefore, it is the matrix of impeller that the utility model adopts with plastics, is positioned at the impeller inserts and the impeller matrix integrated injection molding that impeller is connected with power transmission shaft of impeller bottom centre, again the impeller overcoat of being made by sheet metal in its surface installation one.
Impeller overcoat described in the utility model adopts stainless sheet steel punch forming and polishing, can make impeller have more beautiful outward appearance.
The utility model is owing to adopt double-deck impeller structure, and the metal-coating on surface has not only improved the hardness of impeller, makes impeller be difficult for the wearing and tearing and the scuffing of washings, loss of gloss, and be difficult for producing static, reduced the phenomenon of impeller bottom incrustation; In addition, the metal-coating of impeller can be made into smooth surface, and fineness is high more a lot of than plastics impeller, therefore, also can reduce for the wear rate of washings, thereby improve machine performance, and impeller is had and different in the past beautiful outward appearances.From the angle of technology, no matter the matrix under impeller overcoat parcel is that hardness or surface smoothness can debase the standard, and can reduce because of increasing the cost amplification that overcoat brings.
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1 is the front view of a kind of embodiment of the utility model;
Fig. 2 is the left pseudosection of Fig. 1.
Double-deck impeller shown in Fig. 1 and 2 is a kind of embodiment of the present utility model, impeller is by impeller matrix 2, impeller overcoat 3 and impeller inserts 1 are formed, wherein the metal insert 1 of impeller matrix and impeller is the injection moulding process consubstantiality injection mo(u)lding of adopting in the past, the impeller overcoat then by sheet metal through the punch process moulding, it has the shape of coincideing substantially with impeller matrix surface shape, and the upper surface that has covered matrix 2 comprises centre bore portion and matrix dish edge, it also has the little cavity of formation between some homodisperse fritter convex tendons and the impeller matrix, and impeller overcoat and impeller matrix are combined as a whole through riveted joint.
Two the impeller overcoat of embodiment adopts stainless steel to make, and the surface smoothness height has beautiful outward appearance, and very suitable stainless steel wash bucket with washing machine matches.
Claims (3)
1. double-deck agitation wheel for washing machine, comprise plastics impeller and the impeller inserts 1 that impeller is connected with power transmission shaft that is used for that is positioned at plastics impeller bottom centre, it is characterized in that the plastics impeller as the impeller matrix, an impeller overcoat of being made by sheet metal is installed on its surface.
2. double-deck agitation wheel for washing machine according to claim 1, it is characterized in that described impeller overcoat has the shape of coincideing substantially with impeller matrix surface shape, and the upper surface that has covered matrix 2 comprises centre bore portion and matrix dish edge, and it also has the little cavity of formation between some homodisperse fritter convex tendons and the impeller matrix.
3. double-deck agitation wheel for washing machine according to claim 1 and 2 is characterized in that the riveted joint of impeller overcoat and impeller matrix is one.
