DETAILED DESCRIPTION

[0045] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0046] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “vertical”, “inside” and “outside” are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0047] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0048] like Figures 1 to 4 As shown, the present invention provides a pulsator assembly, which includes a pulsator 1 and a water retaining structure 2. The bottom of the pulsator 1 has a concave cavity that is recessed upward, and is provided with a water return hole 11 that passes through from top to bottom, and the water return hole 11 is connected to the concave cavity. The water retaining structure 2 is arranged on the opening of the concave cavity, and is used to guide the water in the concave cavity to flow to the top of the pulsator 1 through the water return hole 11 when the pulsator 1 rotates.

[0049] In the present invention, a water retaining structure 2 is arranged in the concave cavity opening below the impeller 1, and a water return hole 11 penetrating the concave cavity is arranged on the impeller 1. When the impeller 1 rotates to wash clothes, it can drive the water flow to generate centrifugal force. The centrifugal force throws the water flow to the top of the water retaining structure 2, that is, the outer periphery of the concave cavity of the impeller 1. The water flow returns to the upper side of the impeller 1 through the water return hole 11, and impacts the clothes on the upper part of the impeller 1, thereby increasing the impact force of the water flow above the impeller 1, which can better remove stains and residues on clothes and improve the washing effect.

[0050] The water retaining structure 2 is a water retaining plate 21, and the outer peripheral edge of the water retaining plate 21 is sealed and connected to the opening edge of the concave cavity. The water return hole 11 and the water retaining plate 21 are arranged opposite to each other in the upper and lower parts.

[0051] The water baffle 21 is sealed with the impeller 1 to block the water flowing toward the periphery under the action of centrifugal force, ensuring that all the water entering the concave cavity of the impeller 1 flows out from the water return hole 11, thereby increasing the washing effect.

[0052] The water return hole 11 and the water baffle plate 21 are arranged opposite to each other up and down, so that the concentrated water flow can flow out directly from the water return hole 11, thereby ensuring the impact force and water flow of the water flow.

[0053] The water return hole 11 is arranged near the outer peripheral edge of the impeller 1. Preferably, the water baffle plate 21 extends from the outer periphery to the middle, and the distance between the water baffle plate 21 and the top wall of the concave cavity gradually increases.

[0054] Due to the effect of centrifugal force, water flowing into the cavity of the impeller 1 will be thrown to the periphery of the concave cavity. Setting the return hole 11 on the periphery of the impeller 1 can make the water flow directly out of the return hole 11, avoiding the attenuation of the impact force of the water flow during the reciprocating movement.

[0055] The impeller 1 includes an impeller disc 12 and water-displacing blades 14. The concave cavity of the impeller 1 is arranged on the bottom of the impeller disc 12. The water-displacing blades 14 are arranged on the impeller disc 12 at intervals along the circumferential direction. The water return holes 11 are arranged on the water-displacing blades 14 and between every two adjacent water-displacing blades 14, and are arranged opposite to the outer peripheral portion of the water retaining plate 21.

[0056] The impeller 1 is provided with water-repelling blades 14 arranged at intervals. When the impeller 1 rotates, the water-repelling blades 14 can generate strong vortex and water flow power, so that the water and the clothes are in more complete contact. Through the friction and impact between the water flow and the clothes, the stains and impurities on the clothes can be removed more thoroughly. In addition, the movement of the water-repelling blades 14 can speed up the flow of water and improve the efficiency of the water flow in flushing the clothes, thereby shortening the washing time and saving water and electricity costs. The water-repelling blades 14 can also fully untie the clothes during the rotation process to avoid entanglement between the clothes and reduce the wear and damage to the clothes during the washing process.

[0057] The water return hole 11 is provided on the water-repelling blade 14, which can enhance the water flow power inside the washing machine, make the water and detergent mix more fully, improve the washing effect, and avoid uneven washing, ensuring that the clothes are evenly washed during the washing process. The water return hole 11 is provided between every two adjacent water-repelling blades 14, which can more thoroughly discharge the water entering the concave cavity of the impeller 1, avoid the residual water flow in the concave cavity from colliding with the water flow just entering the concave cavity, and reduce the impact force affecting the washing effect.

[0058] The water-repelling blade 14 is arranged on the upper part of the impeller 12, and is gradually raised from the outer periphery of the impeller 12 to the middle to form an elevated section, and then gradually lowered to the middle to form a lowered section. The elevated section is arranged at the outer peripheral edge of the upper part of the impeller 12. The return water hole 11 includes a first return water hole 111, a second return water hole 112 and a third return water hole 113. The first return water hole 111 is arranged on the elevated section of the water-repelling blade 14. The second return water hole 112 is arranged at the highest point where the elevated section and the lowered section of the water-repelling blade 14 are connected. The third return water hole 113 is arranged on the impeller 1 between every two adjacent water-repelling blades 14.

[0059] The bottom of the water-repelling blade 14 is a cavity, so that the water in the concave cavity of the impeller 1 can be directly sprayed out from the water return hole 11 to avoid the attenuation of the impact force. The water-repelling blade 14 is arranged to protrude upward on the upper part of the impeller 1, which can increase the degree of tumbling of clothes during the washing process.

[0060] The radial extension length of the rising section on the water-repelling blade 14 is smaller than the radial extension length of the falling section. The rising speed of the rising section is greater than the falling speed of the falling section.

[0061] The first water return hole 111 is arranged in the middle of the lowering section of the water-repelling blade 14. When the impeller 1 rotates, after water enters the concave cavity of the impeller 1, it impacts the outer periphery of the concave cavity due to the action of centrifugal force and is discharged along the first water return hole 111, which can maximize the impact force of the water flow, provide stronger flushing ability, better flush and remove stains and dirt on clothes, and make the clothes clean more thoroughly.

[0062] The second water return hole 112 is arranged at the top of the raised section of the water repelling blade 14, and can provide impact water flow at a different angle from the first water return hole 111, so as to distribute water and detergent evenly on the clothes more quickly and speed up the washing process. In addition, multiple water return holes 111 can change the direction and intensity of water flow and reduce the entanglement of clothes during the washing process.

[0063] The third water return hole 113 is arranged on the impeller 1 between every two water-repelling blades 14, which can eliminate the residual water that fails to flow out through the first water return hole 111 and the second water return hole 112, and play a role in enhancing the washing effect. It can also prevent the new water flow in the concave cavity of the impeller 1 from colliding with the residual water in the concave cavity when it is thrown to the periphery under the action of centrifugal force to offset the impact force, thereby maintaining the normal washing ability of the entire impeller assembly.

[0064] The water return holes 11 are installed on the water repelling blades 14 and on the outer periphery of the impeller 12 between every two water repelling blades 14. The water return holes 11 are relatively few in number, which can provide a higher water flow rate and water pressure, and can wash water onto the clothes faster, which helps to reduce the washing time and improve the working efficiency of the washing machine.

[0065] A water guide structure 3 is provided on the bottom surface of the impeller 1 , and is disposed between the bottom wall of the impeller disc 12 and the water baffle 21 , for guiding water to the water return hole 11 .

[0066] In the present invention, the water guide structure 3 is arranged on the bottom surface of the impeller 12. During the washing process, after the water flows into the concave cavity of the impeller 1, it flows toward the periphery of the concave cavity of the impeller 1 under the action of centrifugal force, and then flows along the water guide structure 3 to the position of the water return hole 11, and is discharged through the water return hole 11.

[0067] The water guide structure 3 can make the water flow to the water return hole 11 more concentrated and smooth, reduce the occurrence of reverse flow or dispersion of the water flow, and improve the stability of the washing machine and the impact force of the water flow.

[0068] The water guide structure 3 includes a base 31, a first water guide plate 32 and two second water guide plates 33. The base 31 is arranged on the inner wall of the concave cavity between two adjacent water-displacing blades 14, and is fixedly connected to the water retaining plate 21. The first water guide plate 32 is extended radially inward from the base 31. The two second water guide plates 33 are respectively extended from the base 31 toward the outer circumference of the impeller 1, and are gradually approached toward the water-displacing blades 14 on both sides of the base 31. The return water hole 11 on the impeller disc 12 is arranged between the adjacent sides of the two second water guide plates 33. Preferably, the return water hole 11 on the water-displacing blade 14 is located on the outer ring side of the circumference of the base 31. More preferably, the return water hole 11 on the impeller disc 12 is located on the circumference where the end of the second water guide plate 33 is located.

[0069] In the present invention, the water guide structure 3 has the base 31 installed at the bottom of the impeller 1. The base 31 is connected with a first water guide plate 32 extending radially inward, and two second water guide plates 33 extending from the base 31 to the outer circumference of the impeller 1. The two second water guide plates 33 are gradually arranged from the base 31 to the water-dispelling blades 14 on both sides of the base 31. There is a certain distance between the second water guide plates 33 and the water-dispelling blades 14. The length of the first water guide plate 32 is smaller than the second water guide plate 33. The height of the first water guide plate 32 is higher than the second water guide plate 33. Because the water retaining structure 2 is protruding downward, the height of the first water guide plate 32 is gradually increased from the base 31 to the other end edge, and the height of the second water guide plate 33 is gradually decreased from the base 31 to the other end edge. The water guide structure 3 is arranged in close contact with the water retaining structure 2. The base 31 and the water retaining plate 21 can be connected and installed through the screw hole 22.

[0070] The first water return hole 111 is disposed on the outer ring side of the circumference where the end of the second water guide plate 33 is located, and the second water return hole 112 is disposed between the circumference where the end of the second water guide plate 33 is located and the circumference where the base 31 is located.

[0071] The water retaining structure 2 is provided with a screw hole 22, which can be installed in conjunction with the base 31. The water retaining structure 2 forms a closed channel with the first water guide plate 32 and the second water guide plate 33 of the water guide structure 3. When the impeller 1 rotates, after the water flows into the concave cavity of the impeller 1, it flows along the channel to the positions of the first water return hole 111 and the second water return hole 112, gathers at the cavity of the water diverter blade 14, and flows out of the concave cavity of the impeller 1 through the first water return hole 111 and the second water return hole 112. The residual water that does not flow out through the first water return hole 111 and the second water return hole 112 will flow between the water guide structure 3 and the outer peripheral edge of the concave cavity of the impeller 1, and flow out through the third water return hole 113. The water guide structure 3 and the water retaining structure 2 divide the impeller 1 into multiple areas, and one water diverter blade 14 is installed in each area.

[0072] The water baffle 21 is annular, the edge of the water baffle 21 is sealed and connected to the edge of the opening, and a notch 23 is provided in the middle. Preferably, the water baffle 21 is arranged to protrude gradually downward from the edge along the radial direction to the inner ring.

[0073] In the present invention, the water retaining structure 2 is protruding downward, and a circular notch 23 is provided in the middle. Water in the washing machine can flow into the concave cavity of the impeller 1 through the notch 23, increasing the water inflow into the concave cavity of the impeller 1 and improving the washing effect.

[0074] A boss 15 is provided in the middle of the impeller 1, and the water-repelling blade 14 extends to the boss 15. A through-hole 16 is provided in the middle of the boss 15, and the through-hole 16 is used to install the impeller 1 on the washing machine. A water leakage hole 13 is provided on the periphery of the through-hole 16, which is through from top to bottom, and the water leakage hole 13 is arranged opposite to the notch of the water baffle 21.

[0075] In the present invention, the mounting through hole 16 in the boss 15 can be provided with a pulsator bushing 161. The pulsator bushing 161 is connected to the pulsator shaft of the washing machine, and can drive the entire pulsator 1 to rotate when the pulsator shaft rotates. The rotation of the pulsator 1 can generate a strong water flow and stirring, which can wash clothes more thoroughly. The rotation of the pulsator 1 can also increase the friction between the clothes, which helps to remove stubborn stains and dirt. The rotation of the pulsator 1 can wash clothes quickly and effectively, thereby saving washing time and improving washing efficiency. Since the stirring effect of the rotation of the pulsator 1 is stronger, the contact area between the clothes is increased, and the clothes can be washed more fully. Compared with other types of washing machines, the washing time of the pulsator washing machine is usually shorter.

[0076] A fixing card 162 may be provided in the installation through hole 16 , and a decorative cover 163 may be fixed above the impeller bushing 161 to enhance the aesthetics.

[0077] The water leakage hole 13 is arranged on the impeller 1, which can increase the water inlet of the concave cavity of the impeller 1, increase the water flow rate and impact force of washing clothes, help remove stains on clothes, and improve the washing effect. And the water leakage hole 13 is arranged in the middle of the impeller 1, so that the water flow can flow to various positions of the impeller 1 more evenly, ensuring that the clothes are washed by water flow at all angles during the washing process, thereby improving the washing effect.

[0078] And when water flows into the inner cavity of the impeller 1, the water will form a vortex around the outside of the impeller 1, increasing the contact area between water and clothes, which can better wash away stains and dirt on clothes and make clothes cleaner.

[0079] In the present invention, the water-repelling blade 14 extends to the boss 15 toward the inner ring side, and the top of the raised section of the water-repelling blade 14 is at an end close to the outer periphery of the impeller 1, so the water return hole 11 on the water-repelling blade 14 is arranged at an end away from the boss 15. There is a certain distance between the water return hole 11 and the water leakage hole 13, which can maximize the centrifugal force of the water flow entering the concave cavity of the impeller 1, and avoid the water flow being discharged as soon as it enters the concave cavity without impact force.

[0080] In the present invention, the pulsator 1 is provided with a water return hole 11 and a water leakage hole 13. During the washing process, the water in the washing machine enters the concave cavity of the pulsator 1 through the water leakage hole 13 on the pulsator 1. The centrifugal force generated by the rotation of the pulsator 1 throws the water flow entering the concave cavity of the pulsator 1 toward the periphery of the concave cavity of the pulsator 1, and the water flow flows back to the upper part of the pulsator 1 through the water return hole 11 on the periphery of the pulsator 1 to flush the clothes.

[0081] The above description is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes by using the technical content suggested above without departing from the scope of the technical solution of the present invention.
