The impeller of the washing machine achieves the purpose of preventing clothes from being wound mainly in a mode that when the impeller rotates, the water spraying impeller rotates to drive water flow to be sprayed upwards from the water spraying outlet. Although the above-described technical means solves the problems of a single water flow and low cleaning efficiency to some extent, the following problems are unavoidable. Firstly, because the fan blades of the water spraying impeller are distributed along the radial direction of the impeller shaft, most washing water is thrown out along the radial direction of the impeller shaft in the rotating process of the water spraying impeller instead of directly forming upward water flow to be sprayed out from the water spraying outlet, so that the upward force of the water flow is greatly weakened; and most of the radially thrown washing water hits the side wall of the impeller chamber to produce useless work, and the washing efficiency is obviously reduced. Secondly, the pulsator has a problem of complicated structure because it includes a support member for supporting the impeller shaft and a member for rotating the water jet impeller, in addition to necessary members for generating the upward water current.
Accordingly, there is a need in the art for a new pulsator and a laundry treating apparatus including the same to solve the above-mentioned problems.

A plurality of first apopores 121 have been seted up to the upper surface of bellying 12, and the outer wall in shaft hole 13 still is provided with water lifting structure 14, and water lifting structure 14 sets to and can make the washing water of rim plate 11 below rise along the axial of shaft hole 13 and follow first apopore 121 and erupt.
The washing water below the wheel disc 11 can be lifted along the axial direction of the shaft hole 13 by the water lifting structure 14 and sprayed out of the first water outlet hole 121, and the pulsator 1 of the present invention can make the washing water flow upward along the axial direction of the shaft hole 13, rather than flowing in the radial direction of the shaft hole 13, so that the upward spraying effect is greatly enhanced, and the structure of the pulsator 1 is simplified. In other words, the invention solves the problems of poor spraying effect and complex structure of the impeller 1 of the existing washing machine, effectively improves the spraying effect and the washing efficiency, reduces the cost of the impeller 1 and is suitable for large-scale popularization.
Referring to fig. 2 and 4, the cross section of the wheel disc 11 is substantially in the shape of an arc having a high middle and low ends, the boss 12 is formed by upwardly bulging the center of the wheel disc 11, and the area of the cross section of the boss 12 is gradually reduced in the forming direction of the boss 12 (i.e., from bottom to top in fig. 4). The upper surface of the wheel disc 11 is provided with five water paddles 16, each water paddle 16 extending from the lower end surface of the boss 12 to the upper surface outer edge of the wheel disc 11 in the radial direction of the wheel disc 11. A plurality of second water outlet holes 17 are formed between every two water-moving blades 16, wherein a plurality of second water outlet holes 17 are formed in the blank area between the water-moving blades 16, and a row of second water outlet holes 17 are respectively formed on the two side edges close to the water-moving blades 16. A plurality of third outlet holes 161 (see fig. 2) are also provided on the upper surface of the water paddle 16. Referring to fig. 2, 3 and 4, twelve first water outlet holes 121 are formed in the protruding portion 12, a shaft hole 13 is formed in the center of the lower surface of the protruding portion 12 in a downward extending manner, and the water lifting structure 14 is four propeller blades arranged on the outer wall of the shaft hole 13 along the radial direction of the shaft hole 13. The lower surface of the wheel disc 11 is provided with an annular first reinforcing rib 15, each propeller blade is connected with the inner wall of the first reinforcing rib 15 and the lower surface of the boss 12, the connecting part of the propeller blade and the inner wall of the first reinforcing rib 15 forms a first spiral curve, the lower edge of the propeller blade is flush with the annular lower edge of the first reinforcing rib 15, and the connecting part of the propeller blade and the lower surface of the boss 12 forms a second spiral curve. Preferably, the boss 12, the shaft hole 13, the plurality of propeller blades, and the first reinforcing rib 15 are integrally formed (e.g., the entire pulsator 1 is integrally formed). Of course, the boss 12, the shaft hole 13, the propeller blade, and the first reinforcing rib 15 may be separately formed or partially integrally formed and then attached to the disk 11. In addition, the lower surface of the wheel disc 11 is further provided with two annular second reinforcing ribs 19 and a plurality of water-repellent ribs 18, and each water-repellent rib 18 extends from the innermost first reinforcing rib 15 to the outer edge of the wheel disc 11 along the radial direction of the wheel disc 11.
According to the orientation shown in fig. 4, when the pulsator 1 works, the driving device drives the wheel disc 11 of the pulsator 1 to rotate, in the rotating process, the water stirring blades 16 drive the washing water above the wheel disc 11 to generate vortex, and the water stirring ribs 18 drive the washing water below the wheel disc 11 to be sprayed out above the wheel disc 11 simultaneously through the second water outlet holes 17 and the third water outlet holes 161, so that the friction degree between the clothes and the water stirring blades 16 is reduced. Meanwhile, the washing water enters four water lifting channels formed by the propeller blades, the first reinforcing ribs 15 and the protruding portions 12 in a surrounding mode under the driving of the propeller blades, when the impeller 1 rotates for one circle, the four propeller blades inside the chamber also rotate for one circle, the washing water located below the wheel disc 11 is sucked into the water lifting channels by the propeller blades, the washing water located in the propeller tubes is continuously upwards pushed to the chamber by the propeller blades, and the area surrounded by the cross sections of the protruding portions 12 is gradually reduced along the forming direction of the protruding portions 12, namely the four propeller blades are arranged in a mode of being small in top and large in bottom, so that the space in the channels is smaller and smaller as the propeller blades are driven by the wheel disc 11 to rotate at a high speed, the washing water is rapidly pressurized and flows upwards along the vertical direction, finally, powerful high-pressure jet water flow is formed through the first water outlet holes 121 and is jetted upwards, the powerful water flow supports and suspends clothes, and sprays and brushes the clothes.
As can be seen from the above description, the present invention creatively encloses the water lifting structure 14 (propeller blades), the first reinforcing ribs 15 and the protrusions 12 to form the water lifting channel, so that when the pulsator 1 is running, a strong water jet can be formed to lift up the clothes and brush the clothes, and the ingenious arrangement not only can greatly enhance the water jet effect, reduce the wear of the pulsator 1 to the clothes, but also can effectively avoid the entanglement of the clothes, and improve the washing degree of the clothes. Furthermore, the area enclosed by the cross section of the convex part 12 is gradually reduced along the forming direction of the convex part 12, so that the water lifting channel is gradually narrowed and the pressure is gradually increased in the process that the washing water is pushed upwards by the propeller blades, and the pressure and the spraying effect of the water spraying flow are ensured. In addition, under the condition of forming good spraying effect and washing effect, the invention also omits a supporting component for supporting the impeller shaft and parts for rotating the water spraying impeller and the like in the prior art, greatly simplifies the structure of the impeller 1, reduces the production cost of the impeller 1 and improves the competitiveness of the product.
