[0020] The purpose of this invention is to provide a washing machine that facilitates the removal of the impeller cover without the need for disassembly tools, is simple to operate, has high disassembly and assembly efficiency, and does not scratch the impeller cover.

[0021] To achieve this objective, the present invention adopts the following technical solution:

[0040] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0042] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0043] A top-loading washing machine includes a tub for containing water and a rotating drum rotatably mounted within the tub. Additionally, a pulsator assembly that rotates to generate water flow is mounted at the bottom of the rotating drum. The pulsator assembly rotates in alternating directions to generate water flow. The wash water and clothes move while being agitated by the water flow generated by the pulsator assembly, thereby achieving the washing of the clothes.

[0044] The impeller assembly is installed at the bottom of the rotating drum. In the prior art, the impeller cover of the impeller assembly is fixed by a snap-fit ​​structure. Removing the impeller cover requires a disassembly tool, and there is a risk of scratching the surface of the impeller cover, affecting its appearance. Furthermore, disassembly is relatively cumbersome. To address the above problems, this embodiment provides an impeller assembly and a washing machine to solve the aforementioned technical issues.

[0045] Specifically, such as Figure 1 and Figure 2 As shown, the impeller assembly provided in this embodiment includes an impeller cover 1, a rotating wheel 2, and a fastener 3. The impeller cover 1 is fixed to other components of the washing machine via the rotating wheel 2 and the fastener 3. This component is typically the bottom of the rotating drum of the washing machine.

[0046] like Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the impeller cover 1 has a first mounting portion 12 and a first mounting hole 11 in its middle. The first end of the impeller 2 has a second mounting portion 21 that is detachably connected to the first mounting portion 12 along the axial direction of the impeller 2. The middle of the impeller 2 has a second mounting hole 22 that is coaxial with the first mounting hole 11. After the second mounting portion 21 is connected to the first mounting portion 12, the second mounting hole 22 is coaxial with the first mounting hole 11.

[0047] The first end of the fastener 3 passes through the second mounting hole 22 and is detachably connected to the first mounting hole 11. Simultaneously, the first end of the fastener 3 connects to other components of the washing machine, thus achieving a fixed installation of the impeller cover 1. The second end of the rotor 2 is provided with a third mounting portion 23, and the fastener 3 is provided with a fourth mounting portion 31 detachably connected to the third mounting portion 23. The rotor 2 can drive the fastener 3 to rotate together. The second end of the rotor 2 is also provided with a clamping member 24 that abuts against the fastener 3 and keeps the second mounting portion 21 connected to the first mounting portion 12, ensuring a stable connection between the rotor 2 and the impeller cover 1.

[0048] In this embodiment, the impeller assembly includes an impeller cover 1 fixed by a rotating wheel 2 and a fastener 3. The rotating wheel 2 is connected to a second mounting part 21 and a first mounting part 12, preventing the rotating wheel 2 from rotating relative to the impeller cover 1 axially, while allowing the rotating wheel 2 to separate from the impeller cover 1 axially. The fastener 3 is used to fix the impeller cover 1 to other components of the washing machine. The first end of the fastener 3 passes through a second mounting hole 22 and is detachably connected to a first mounting hole 11. To facilitate the removal of the fastener 3 and thus the impeller cover 1, the fastener 3 is connected to the rotating wheel 2 by a third mounting part 23 and a fourth mounting part 31, allowing the fastener 3 to rotate axially with the rotating wheel 2. When removing the fastener 3, the rotating wheel 2 is lifted to press the clamping member 24, causing the second mounting part 21 to separate from the first mounting part 12. Then, the rotating wheel 2 is rotated to separate the fastener 3 from the other components of the washing machine and the impeller cover 1, thereby achieving the removal of the impeller cover 1 without the need for removal tools and without scratching the impeller cover 1. This structure facilitates the removal and installation of the impeller cover 1 by the operator.

[0049] Combination Figure 7 As shown, when disassembling the impeller cover 1, the clamping member 24 connects the second mounting part 21 of the impeller 2 to the first mounting part 12. The second mounting part 21 can be detached from the first mounting part 12 along the axial direction. Therefore, when disassembling the impeller cover 1, the impeller 2 is first lifted to separate the second mounting part 21 from the first mounting part 12, thus separating the impeller 2 from the impeller cover 1. The impeller 2 can rotate relative to the impeller cover 1 around the axial direction. At the same time, under the action of the third mounting part 23 and the fourth mounting part 31, the rotating impeller 2 drives the fastener 3 to rotate with the impeller 2, so that the fastener 3 is separated from other parts of the washing machine and the impeller cover 1, and the impeller cover 1 can be disassembled.

[0050] Combination Figure 8 As shown, when installing the impeller cover 1, the impeller cover 1 is placed on the component of the washing machine to be installed, the impeller 2 is placed on the impeller cover 1, the second mounting part 21 is connected to the first mounting part 12, the fastener 3 passes through the second mounting hole 22 and is connected to the first mounting hole 11 and other components of the washing machine, the third mounting part 23 is connected to the fourth mounting part 31, and the abutting member 24 abuts against the fastener 3, so that the second mounting part 21 and the first mounting part 12 remain connected.

[0051] In this embodiment, refer to Figure 3 , Figure 6 and Figure 9As shown, the second mounting hole 22 of the rotating wheel 2 has a first boss 25 circumferentially arranged on its hole wall. The first end of the first boss 25 is flush with the first end of the rotating wheel 2. The second mounting part 21 is disposed at the first end of the first boss 25, and the third mounting part 23 is disposed at the second end of the first boss 25. The first boss 25 provided on the hole wall of the second mounting hole 22 provides a mounting platform for the second mounting part 21 and the third mounting part 23, facilitating their installation.

[0052] Optionally, the rotating wheel 2 has a ring-shaped structure, specifically it can be circular, elliptical, or rectangular, etc., without specific limitation. The hollow part of the rotating wheel 2 is the second mounting hole 22. The second mounting hole 22 is preferably located at the center of the rotating wheel 2 so that the rotating wheel 2 is evenly stressed when connected to the impeller cover 1 and the fastener 3.

[0053] In order to improve the structural strength of the wheel 2, in this embodiment, the cross section of the wheel 2 along the axial direction is a U-shaped structure, the first boss 25 is disposed on the inner side wall of the inner layer plate of the wheel 2, and the first boss 25 extends to the first end of the inner layer plate.

[0054] Since the second mounting part 21 is detachably connected to the first mounting part 12 along the axial direction of the rotating wheel 2, the first mounting part 12 may optionally include one of a protrusion and a groove, and the second mounting part 21 may include the other of a protrusion and a groove. The protrusion can be inserted into the groove. This structure realizes the detachable connection between the second mounting part 21 and the first mounting part 12 along the axial direction of the rotating wheel 2, and the structure is simple and easy to disassemble and install.

[0055] Specifically, in this embodiment, the first mounting part 12 includes a groove, and the second mounting part 21 includes a protrusion. Since the rotating wheel 2 in this embodiment has a circular structure, and the first protrusion 25 also has a circular structure, the protrusion is preferably disposed on the end face of the first end of the first protrusion 25, and the protrusion and the first protrusion 25 are integrally formed and connected, which improves the structural strength of the connection between the protrusion and the first protrusion 25, and facilitates the insertion of the protrusion into the groove on the impeller cover 1. Therefore, to facilitate the processing of the protrusion, the cross-section of the protrusion is an arc-shaped structure, and the curvature of the protrusion is consistent with the curvature of the first protrusion 25. Correspondingly, the cross-section of the groove is also an arc-shaped structure.

[0056] In other embodiments, the first mounting part 12 and the second mounting part 21 may also have other structures, which are not specifically limited here.

[0057] In this embodiment, the impeller cover 1 is provided with a first mounting hole 11 in the middle, preferably at the center of the impeller cover 1, so as to generate a uniform water flow when the impeller cover 1 rotates.

[0058] Multiple first mounting portions 12 are provided, and the multiple first mounting portions 12 are arranged circumferentially around the first mounting hole 11. After the rotating wheel 2 is installed on the impeller cover 1, the second mounting hole 22 is coaxially arranged with the first mounting hole 11. Corresponding to the first mounting portions 12, multiple second mounting portions 21 are provided, and the multiple second mounting portions 21 are arranged circumferentially around the second mounting hole 22, corresponding to the first mounting portions 12.

[0059] In this embodiment, the second end of the fastener 3 is provided with a second boss 32 along the circumferential direction, and the fourth mounting part 31 is disposed on the second boss 32. After the fourth mounting part 31 is connected to the third mounting part 23, the second boss 32 overlaps the first boss 25 to limit the position of the fastener 3 connected to the impeller cover 1. When the roller 2 is lifted, the second boss 32 provides support for the lifting of the roller 2 so that the fastener 3 moves upward with the roller 2 and disengages from the impeller cover 1.

[0060] Optionally, the third mounting part 23 is detachably connected to the fourth mounting part 31 along the axial direction of the fastener 3, which facilitates the installation of the fastener 3 on the impeller cover 1, thereby facilitating the matching connection between the fastener 3 and the wheel 2.

[0061] Therefore, in this embodiment, the third mounting part 23 includes one of a protrusion and a groove, and the fourth mounting part 31 includes the other of a protrusion and a groove, with the protrusion capable of being inserted into the groove. This structure enables a detachable connection between the fourth mounting part 31 and the third mounting part 23 along the axial direction of the rotating wheel 2, and is simple in structure, facilitating disassembly and installation.

[0062] Specifically, in this embodiment, the third mounting part 23 includes a protrusion, and the fourth mounting part 31 includes a groove. Since the rotating wheel 2 in this embodiment has a circular structure, and the first boss 25 also has a circular structure, the protrusion is preferably disposed on the end face of the second end of the first boss 25, and the protrusion is integrally formed and connected with the first boss 25, improving the structural strength of the connection between the protrusion and the first boss 25, and facilitating the insertion of the protrusion into the groove on the fastener 3. Therefore, to facilitate the processing of the protrusion, the cross-section of the protrusion is an arc-shaped structure, and the curvature of the protrusion is consistent with the curvature of the first boss 25. Correspondingly, the cross-section of the groove on the fastener 3 is also an arc-shaped structure.

[0063] The groove on the fastener 3 is provided on the end face of the second boss 32 near the first boss 25 so that the boss can be inserted into the groove.

[0064] In other embodiments, the third mounting part 23 and the fourth mounting part 31 may also have other structures, which are not specifically limited here.

[0065] The clamping member 24 tends to keep the second mounting portion 21 connected to the first mounting portion 12. When the impeller cover 1 is removed, the clamping member 24 can be compressed to separate the impeller 2 from the impeller cover 1. Specifically, the clamping member 24 includes an elastic member, one end of which is connected to the impeller 2, and the other end of which can abut against the fastener 3. The elastic member always tends to keep the second mounting portion 21 connected to the first mounting portion 12.

[0066] Specifically, when the fastener 3 is connected to the impeller cover 1 and the fastener 3 presses against the elastic element, the elastic element is squeezed. In order to release the squeezed force, the roller 2 moves toward the impeller cover 1, thereby making the second mounting part 21 always connected to the first mounting part 12.

[0067] Optionally, the elastic element provided in this embodiment includes an L-shaped plate. The vertical plate of the L-shaped plate is connected to the rotating wheel 2, and the horizontal plate of the L-shaped plate is elastically connected to the vertical plate. The included angle between the horizontal plate and the vertical plate is an obtuse angle, and the horizontal plate of the L-shaped plate is configured to abut against the fastener 3. The obtuse angle between the horizontal plate and the vertical plate provides deformation space for the horizontal plate, allowing the elastic element to accumulate elastic pressure to drive the rotating wheel 2 to move towards the impeller cover 1. Furthermore, the structure of this elastic element is simple and easy to process.

[0068] Optionally, the L-shaped plate can be a plate with elastic deformation properties, such as a spring plate.

[0069] Based on the structure of the wheel 2 described above, an elastic element is disposed on the second end face of the first boss 25 on the wheel 2 to abut against the end face of the second boss 32 of the fastener 3, so that the elastic element accumulates elastic force in the axial direction of the wheel 2, thereby causing the wheel 2 to have a tendency to move toward the impeller cover 1.

[0070] Multiple elastic elements are spaced apart along the axial direction of the first boss 25 to increase the force that moves the wheel 2 toward the impeller cover 1.

[0071] In other embodiments, the elastic element includes a spring, one end of which is connected to the wheel 2, and the other end of the spring is a free end for abutting against the fastener 3.

[0072] In this embodiment, the fastener 3 is threadedly connected to the first mounting hole 11, which has a simple connection structure and is easy to install and disassemble.

[0073] Specifically, an internal thread is provided on the wall of the first mounting hole 11, and an external thread matching the internal thread is provided on the outer wall of one end of the fastener 3.

[0074] Optionally, the fastener 3 has a cylindrical structure, which facilitates the connection of the fastener 3 with the impeller 2 and the impeller cover 1, while also reducing the overall weight of the impeller assembly.

[0075] This embodiment also provides a washing machine, which is a pulsator washing machine, and the washing machine includes the pulsator assembly described above.

[0076] The washing machine also includes a rotating drum, with the pulsator assembly installed at the bottom of the rotating drum. The pulsator cover is fixed to the bottom of the rotating drum by a roller 2 and fasteners 3, making it easy to remove and install without the need for tools, thus avoiding scratches on the pulsator cover.

[0077] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
