In the above scheme, the pulsator washing machine mainly drives clothes to be washed by stirring of the pulsator under the general condition, but the clothes are not easy to be scattered at the center and are easy to be wound together. However, because the central rotating wheel 3 rotates along the central shaft on the wave wheel or rotates along the central shaft connected with the wave wheel, the bottom of the central rotating wheel 3 is contacted with the surface of the wave wheel under the action of gravity, and is subjected to friction force during rotation, the friction coefficient between plastics is larger, and the hidden trouble of damage is caused after a long time; in addition, there is the space between traditional center runner bottom and the impeller surface, produces the skew easily when center runner is rotatory, leads to center runner and impeller surface local friction frequent, produces wearing and tearing or other directions and produces bigger space, blocks clothing or batting etc. easily for center runner frictional force is bigger, change the damage. The disassembly and replacement of the impeller need to be operated by professional persons, and the impeller is difficult to disassemble and replace by a client, so that the trouble is increased for the client. The invention is provided with the smooth supporting structure, reduces the friction between the central rotating wheel and the impeller, ensures that the water flow at the center is simple and regular, does not wind clothes, enhances the washing effect and also reduces the damage caused by the friction of the central rotating wheel 3 on the surface of the impeller. The smooth support structure may be provided on the impeller, or on the central wheel 3, preferably on the impeller.
Further, smooth bearing structure detachable connects on impeller body 1, the rotatable setting of center runner 3 is in smooth bearing structure top.
Further, the diameter of the outer edge of the smooth supporting structure is larger than or equal to the outer diameter of the bottom of the central rotating wheel 3.
In the scheme, the diameter of the outer edge of the smooth supporting structure is larger than or equal to the outer diameter of the bottom of the central rotating wheel 3, so that the bottom of the central rotating wheel 3 is prevented from contacting with the impeller. The smooth supporting structure isolates the bottom of the central rotating wheel 3 from the wave wheel body 1.
Further, the smooth supporting structure is a metal gasket 4, and the metal gasket 4 is clamped or connected with a screw thread or connected to the pulsator body 1 through a screw 41.
In the above scheme, smooth bearing structure is metal gasket 4, because the coefficient of friction between metal and the plastics is low, metal gasket 4 does not increase the resistance of center runner 3 when preventing 3 bottoms of center runner wearing and tearing impeller for the rotation of center runner 3 is not influenced.
Further, the central rotating wheel 3 is of a hemispherical structure, a plurality of bumps 31 are arranged on the surface of the central rotating wheel 3, and preferably, the bumps 31 are uniformly and circumferentially arranged on the surface of the central rotating wheel 3. Preferably, the central rotating wheel 3 is a hollow spherical structure, a plurality of ribs for increasing strength and supporting are arranged in the central rotating wheel 3, and a rotating wheel cover 32 is detachably arranged on the top 21 of the central rotating wheel 3.
In the above scheme, the central rotating wheel 3 is provided with the projection 31, so that the overturning effect of the central rotating wheel 3 on the clothes is enhanced, and the clothes are prevented from being accumulated and wound at the center. The projection 31 extends circumferentially uniformly along the surface of the central rotor 3, and two or more circles of the projection 31 are arranged on the surface of the central rotor 3. The hollow central wheel 3 reduces the mass. Meanwhile, space is provided for installing the metal gasket 4, and the contact area of the metal gasket 4 is small.

The impeller of the traditional washing machine is provided with a plurality of stirring blades 2 for enhancing the washing effect, but the stirring blades 2 are added, so that the water flow is complicated when the friction between the water flow and clothes is increased, and the increased stirring blades 2 reduce the space for the clothes to be distributed, so that the clothes are easy to wind, and the washing effect is poor. The impeller washing machine is provided with the two convex stirring blades 2 which extend from the center along the radial direction of the impeller body 1, the two stirring blades 2 extend on the same diameter along the radial direction, space is provided for horizontal overturning of clothes, the stirring blades 2 are enabled to break up the clothes more easily, the clothes are overturned more easily, the washing effect is improved, meanwhile, the drying uniformity and the drying effect are improved for the impeller washing machine integrating washing and drying, meanwhile, winding is avoided, and wrinkles on the clothes after drying are few; the impeller stirring blade 2 can ensure that the direction of the washing water flow is simple and the strength is high, and simultaneously, the distribution space is increased for clothes, so that the simple high-strength water flow is in full friction contact with the clothes, the clothes are scattered and are not easy to wind, and the washing and/or drying effect is greatly improved; when dewatering, the space for distributing the clothes is large, the clothes are more easily scattered and not wound, and the dewatering effect is good. Moreover, the stirring blade 2 of the invention is higher than the stirring blade 2 of the common impeller, so that the impact and the stirring effect of the stirring blade 2 on water flow are increased, detergent and the like can be fully mixed with water, and the cleaning effect of the washing machine is improved.
Further, the stirring blade 2 is wide at the bottom and gradually narrows towards the top, the stirring blade 2 includes a first side surface 22 and a second side surface 23 extending from the top 21 to the pulsator chassis 11, the first side surface 22 and the second side surface 23 are located at two radial sides of the stirring blade 2, and a curve of the intersection of the first side surface 22 and the second side surface 23 with the pulsator body 1 is substantially parallel to the radial direction of the stirring blade 2. The deviation angle between the intersecting curve of the first side surface 22 and the second side surface 23 with the impeller body 1 and the radial direction of the stirring blade is less than or equal to 6 degrees, and the deviation directions of the two are opposite along the radial direction.
In the above-mentioned scheme, traditional impeller stirring leaf designs into the molding that widens gradually from the center to the outward flange, but this type of stirring leaf occupies the impeller space big, the rivers constantly change the direction along the extending direction of stirring leaf and form different rivers, cause the rivers disorder easily, and interact weakens the rivers intensity between each direction rivers, the clothing is extremely easily twined in center department and is knoed, the friction between rivers and the clothing is also not strong, the rivers weak and the direction of production all are different, the space that can supply the clothing upset is little, the clothing is easily twined in central zone and is knoed. According to the invention, the two stirring blades 2 which extend in the radial direction and have the same diameter are arranged, and the intersecting curves of the first side surface 22 and the second side surface 23 of each stirring blade 2 and the impeller body 1 are basically parallel to the radial direction of the stirring blade 2, so that the stirring blades 2 drive water flow to be gradually enhanced from the center to the outside, the water flow direction is simple and basically unchanged, pure water flow which is gradually enhanced in the same direction is generated, the washing effect is enhanced, and meanwhile, clothes are not easy to accumulate in the center position to be wound and knotted. The first side 22 and the second side 23 smoothly transition to the bottom plate 11, so that the surface of the stirring blade 2 is free from projections for scraping clothes, the shape of reversible clothes is kept, and the resistance of the stirring blade 2 to the clothes is reduced.
Further, the first side surface 22 and the second side surface 23 are asymmetric in shape, and the steepness of the first side surface 22 and the steepness of the second side surface 23 are different; the stirring blade 2 is centrosymmetric.
In the above scheme, the first side surface 22 and the second side surface 23 are asymmetric, the steepness of the first side surface 22 is different from that of the second side surface 23, and the stirring blades 2 are centrosymmetric, so that the stirring blades 2 have two different functions on clothes in the forward and reverse rotation process of the washing machine impeller, and the clothes between the stirring blades 2 are also subjected to the two different functions, thereby preventing the clothes from being wound and turning over the clothes more easily. The first side 22 and the second side 23 may both be inclined or both be curved or one curved and one inclined.

The inner side surface 24 and the outer side surface 25 are smoothly transited to the first side surface 22 and the second side surface 23, respectively. The inner side surface 24 extends from the top 21 to the chassis 11 in the central area of the pulsator, and the outer side surface 25 extends from the top 21 to the outer edge of the chassis 11. The length of the outer edge of the stirring blade 2 is 5% -30% of the outer circumference of the impeller chassis 11. The length of the inner edge of the stirring blade 2 wrapping the central rotating wheel 3 is more than 20% of the length of the outer edge of the stirring blade 2, the distance between the outer edge of the stirring blade 2 and the outer edge of the chassis 11 is less than 10mm, and the percentage of the area of each stirring blade 2 in the whole impeller chassis 11 is more than 10%.
In the scheme, compared with the traditional stirring blade with the inner edge far smaller than the outer edge, the length of the inner edge and the outer edge of the stirring blade 2 is basically the same, so that the area of the stirring blade 2 is large, compared with the traditional stirring blade 2 with the inner edge far smaller than the outer edge, the stirring blade 2 obviously enhances the water flow strength at the inner edge of the stirring blade 2, the water flow is simple, no winding is generated, during drying, clothes are easily scattered in the upper space, the lower space, the middle space and the like by the stirring blade 2, the winding is avoided, the drying effect is good, and wrinkles are few. The inner side surface 24 and the outer side surface 25 provide radial overturning acting force for the clothes, and the inner side surface 24 and the outer side surface 25 are in smooth transition with the first side surface 22 and the second side surface 23 respectively, so that the resistance of the stirring blades 2 to the clothes is reduced. The inner side surface 24 starts to extend from the top 21 to the chassis 11 in the central area of the impeller rapidly, the inner side surface 24 is a cambered surface which is wide at the bottom and gradually narrows towards the top 21, gaps exist among the inner side surfaces 24 of the stirring blades 2, the edges of the inner side surfaces 24 of the stirring blades 2 are not intersected, if the center of the impeller further comprises a central rotating wheel 3, the inclination angle of the inner side surface 24 is relatively large, if the center of the impeller is provided with a raised central part and does not comprise a rotating wheel, the inclination angle of the inner side surface 24 is relatively small, so that clothes are prevented from being left and wound in the central area. The outer side surface 25 extends from the top part 21 to the outer edge of the chassis 11 quickly, the inclination angle of the outer side surface 25 is large, and the outer side surface is close to the outer edge of the chassis 11 as much as possible, so that the turnover function of clothes at the edge of the washing tub is enhanced, the clothes are prevented from being retained or accumulated at the edge of the washing tub, and the washing and/or drying effect is increased. The inner side 24 and the outer side 25 may be both inclined or curved or one inclined and one curved. The distance between the outer edge of the stirring blade 2 and the outer edge of the chassis 11 is less than 10mm, the turnover effect of clothes at the edge of the washing barrel is enhanced, the clothes are prevented from being retained or accumulated at the edge of the washing barrel, and the washing and/or drying effect is increased. The length of the outer edge of the stirring blade 2 is 5% -30% of the outer circumference of the impeller chassis 11, the outer edge of the stirring blade 2 is wide, the area of the stirring blade 2 is large, and the overturning effect of the stirring blade 2 is strong.

The inner edge of the stirring blade 2 is at least partially wrapped around the central rotating wheel, and the inner edge of the stirring blade 2 is as close to the central position as possible, so that clothes can be scattered and turned over more easily, and the clothes are prevented from being wound. The area of each stirring blade 2 accounts for more than 10 percent of the area of the whole impeller chassis 11, so that the size of each stirring blade 2 is larger than that of the stirring blade 2 of a common impeller, the effect of stirring water flow by the impeller is strong, and the washing effect is obviously enhanced.
Further, the chassis 11 of the pulsator body 1 is recessed downward, and the depth of the downward recess is greater than 10 mm.

In the scheme, the through hole can be used as a water through hole to increase the water circulation amount between the inner barrel and the outer barrel during washing, can also be used as a drying air inlet to improve the drying effect, and also enhances the attractive effect of the impeller. Moreover, during washing, the through holes distributed in the centrifugal involute form a plurality of small water flows in the centrifugal involute direction, so that clothes are prevented from being wound, meanwhile, the contact friction area of the water flows and the clothes is increased, and the washing effect is better.
