Description

Technical Field

[0001] This invention relates to the field of garment processing equipment technology, and more particularly to impeller components and garment processing equipment. Background Technology

[0002] As a common household washing machine, the pulsator is one of its core components. The pulsator usually includes the pulsator body and blades set on the pulsator body. The pulsator body drives the blades to rotate and disturb the water flow, so as to agitate and wash the clothes.

[0003] Existing impellers typically only have blades, which can produce a certain stirring effect, but cannot generate multi-directional water flow for rinsing. This results in poor stirring and washing effects, especially when dealing with larger or heavier clothes, as it is difficult to generate a water flow with sufficient intensity, leading to poor washing results.

[0004] Therefore, there is an urgent need for a pulsator assembly and clothing processing equipment to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a pulsator assembly that improves the agitation and washing effect on clothes, thereby increasing the washing ratio.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A pulsator assembly, rotatably mounted within a garment processing device, comprises:

[0008] The impeller body has multiple blades protruding from it, and the blades are arranged at intervals along the circumference of the impeller body.

[0009] A roller, rotatably mounted on the impeller body, wherein the axis of the roller gradually moves away from the axis of the impeller body in a bottom-to-top direction; and / or,

[0010] A rotating wheel is rotatably mounted on the impeller body, and along the direction from bottom to top, the axis of the rotating wheel gradually approaches the axis of the impeller body.

[0011] Through the synergistic action of the blades, rollers, and impellers, multi-directional and multi-layered water flow is generated when the impeller body rotates, significantly enhancing the impact and tumbling effect of the water flow on clothes, thereby improving the agitation and cleaning effect of clothes, increasing the washing ratio. Furthermore, since both the rollers and impellers are rotated on the impeller body, they can effectively reduce friction between clothes and the impeller components, significantly reducing wear and tear on clothes, extending the service life of clothes, and improving the user experience.

[0012] Optionally, the impeller body has a first seat protruding from it, and the first seat has a first mounting groove. Along the radial direction of the impeller body, the two ends of the roller are rotatably connected to the two end walls opposite to the first mounting groove, and at least part of the roller protrudes from the first mounting groove.

[0013] The raised first seat and the first mounting groove on the first seat provide a stable mounting position for the roller, ensuring the stability and durability of the roller during rotation. Furthermore, the raised first seat, combined with the roller rotatably mounted on it, forms a blade-like turbulence structure, which effectively enhances the turbulence of the water flow, enriches the water flow path, and ensures full contact between the water and the clothes, thereby improving the washing effect.

[0014] Optionally, the roller is constructed as a single piece, which simplifies the roller's processing, improves its structural strength, increases its manufacturing efficiency, and further reduces production costs.

[0015] Alternatively, the roller includes a roller body, the inside of which is provided with a hollow portion, one end of which is provided with a first shaft portion, and the other end is provided with an opening communicating with the hollow portion;

[0016] The cover is connected to the roller body and seals the opening. The end of the cover away from the roller body is provided with a second shaft. The first shaft and the second shaft are rotatably connected to the two end walls opposite to the first mounting groove, respectively.

[0017] The hollow section significantly reduces the overall weight of the roller, thereby reducing energy consumption during the rotation of the impeller and improving the operating efficiency of the garment processing equipment. At the same time, the detachable connection between the cover and the roller body makes the installation, disassembly, and maintenance of the roller more convenient.

[0018] Optionally, the outer wall of the roller body is provided with a plurality of strip-shaped grooves spaced apart along the circumference of the roller body, thereby forming a protrusion between two adjacent grooves. The alternating structure of grooves and protrusions generates a moderate friction force between the roller and the clothes, effectively driving the roller to rotate around its own axis, thereby improving the washing effect.

[0019] Optionally, the roller is a frustum-shaped roller or a conical roller. The cross-sectional area of ​​the end of the frustum-shaped roller or the conical roller near the rotation center of the impeller body is smaller than the cross-sectional area of ​​the end of the roller away from the rotation center of the impeller body. The smaller width of the roller at the rotation center of the impeller body can reduce the resistance of the inner water flow and promote the water flow to the outside, while the larger width at the end away from the rotation center enhances the thrust and impact of the outer water flow, thereby forming a stronger radial and axial composite water flow. This design significantly improves the three-dimensionality and turbulence intensity of the water flow, thereby improving the washing effect.

[0020] Alternatively, the roller may be a cylindrical roller; cylindrical rollers have a simpler structure, are easier to process and manufacture, and improve the production efficiency of rollers.

[0021] Optionally, the impeller body has a frustum at its rotation center, and multiple blades are spaced apart circumferentially along the frustum. The height of each blade gradually increases from the end closer to the rotation center of the impeller body to the end farther away from the rotation center.

[0022] The truncated cone section, as a protruding structure located at the center of rotation of the impeller body, can effectively guide the water flow from the center outward to form a stable radial water flow base, while enhancing the structural strength of the impeller body and ensuring stability and durability during high-speed rotation.

[0023] Optionally, the frustum portion is provided with a pulsator cover, which is fixedly connected to the frustum portion. The pulsator cover is provided with a first protruding rib. The pulsator cover can play an auxiliary stirring role, further improving the washing effect. Moreover, the pulsator cover can be fixed to the frustum portion in various installation methods, which facilitates the assembly of the pulsator cover and the frustum portion and improves the assembly flexibility.

[0024] Optionally, the impeller body is further provided with a second seat, which is located between two adjacent blades. The mounting surface of the second seat is inclined toward the rotation center of the impeller body, and the axis of the impeller is perpendicular to the mounting surface of the second seat. The mounting surface is inclined toward the rotation center of the impeller body, so that the axis of the impeller and the axis of the impeller body form an angle β. This inclined impeller arrangement can drive the water flow to form a complex water flow when the impeller body rotates, thereby improving the washing effect.

[0025] Optionally, one of the second base and the impeller is provided with a snap-fit ​​part, and the other of the second base and the impeller is provided with a mating part. The snap-fit ​​part can engage with the mating part, and the impeller can rotate around its own axis. This ensures the positional stability of the impeller when the impeller body rotates at high speed, prevents loosening or displacement, and thus ensures that the impeller continuously generates a stable turbulent water flow.

[0026] The purpose of this invention is to provide a garment processing device that can improve the stirring and washing effect of garments and increase the washing ratio.

[0027] To achieve this objective, the present invention adopts the following technical solution:

[0028] A garment processing device is characterized by comprising a drum assembly and the aforementioned impeller assembly, wherein the impeller assembly is disposed within the drum assembly, and the impeller assembly increases the agitation and cleaning effect on the garments, significantly improving the washing ratio of the garment processing device and enhancing the user experience.

[0029] Beneficial effects:

[0030] The impeller assembly provided by this invention includes an impeller body, rollers, and / or rotating wheels. Multiple blades protrude from the impeller body, spaced circumferentially. Both the rollers and the impeller are rotatably mounted on the impeller body. From bottom to top, the axis of the rollers gradually moves away from the axis of the impeller body, while the axis of the rotating wheels gradually moves closer to the axis of the impeller body. Both the rollers and the rotating wheels can rotate freely around their own axes. Through the synergistic effect of the blades, rollers, and rotating wheels, multi-directional and multi-layered water flow is generated when the impeller body rotates, increasing the agitation and cleaning effect on clothes, improving the washing ratio. Furthermore, the rotatable mounting of the rollers and rotating wheels on the impeller body effectively reduces friction between clothes and the impeller assembly, significantly reducing wear and tear on clothes, extending their lifespan, and improving the user experience.

[0031] The garment processing device provided by the present invention includes a drum assembly and the aforementioned impeller assembly. The impeller assembly is disposed inside the drum assembly. The impeller assembly increases the stirring and cleaning effect on the garments, significantly improves the washing ratio of the garment processing device, and enhances the user experience.

[0046] Example 1

[0047] This embodiment provides a pulsator assembly, which is rotatably mounted inside a garment processing device to agitate and wash the garments. Figures 1-5 As shown, the impeller assembly includes an impeller body 100, a roller 200, and a rotor 300. The impeller body 100 has multiple protruding blades 110, which are spaced apart circumferentially along the impeller body 100. The roller 200 and rotor 300 are rotatably mounted on the impeller body 100. From bottom to top, the axis of the roller 200 gradually moves away from the axis of the impeller body 100, while the axis of the rotor 300 gradually moves closer to the axis of the impeller body 100. Both the roller 200 and rotor 300 can rotate freely around their own axes. The impeller body 100 is equipped with multiple blades 110. The synergistic effect of rollers 200 and impellers 300 generates multi-directional and multi-layered water flow (such as horizontal vortex, vertical vortex, and inclined vortex) when the impeller body 100 rotates. This significantly enhances the impact and tumbling effect of the water flow on the clothes, thereby improving the agitation and cleaning effect, increasing the washing ratio. Furthermore, since both rollers 200 and impellers 300 are rotatably mounted on the impeller body 100, they can effectively reduce friction between the clothes and the impeller components, significantly reducing wear and tear on the clothes, extending the service life of the clothes, and improving the user experience.

[0048] Optionally, such as Figure 2 and Figure 3 As shown, a first seat 120 protrudes from the impeller body 100, and a first mounting groove 121 is provided on the first seat 120. Along the radial direction of the impeller body 100, the two ends of the roller 200 are rotatably connected to the two end walls opposite to the first mounting groove 121, with at least a portion of the roller 200 protruding from the first mounting groove 121. The protruding first seat 120 and the first mounting groove 121 on the first seat 120 provide a stable mounting position for the roller 200, ensuring the stability and durability of the roller 200 during rotation. Furthermore, the protruding first seat 120, combined with the roller 200 rotatably mounted on the first seat 120, forms a blade-like turbulence structure, which can effectively enhance the turbulence effect of the water flow, enrich the water flow path, and ensure that the water flow fully contacts the clothes, thereby improving the washing effect of the clothes.

[0049] For example, in this embodiment, the impeller body 100 is provided with three blades 110, three rollers 200, and six rotating wheels 300. The three blades 110 are arranged circumferentially around the impeller body 100, with an angle of 120° between two adjacent blades 110. Between two adjacent blades 110, there is one roller 200 and two rotating wheels 300. The axis of the roller 200 makes an angle of 60° with the adjacent two blades 110. Each roller 200 has a rotating wheel 300 on each side. The axis of the rotating wheel 300 extends axially along the impeller body 100 and moves from bottom to top towards the center of rotation, further guiding the water flow to form a three-dimensional flow field that interweaves axial and radial directions. Compared with the traditional single impeller design, this embodiment significantly improves the diversity and intensity of the water flow through the synergistic effect of the blades 110, rollers 200, and rotating wheels 300, thereby improving the washing efficiency and cleanliness of larger or heavier clothes.

[0050] In other embodiments, the structure of the impeller assembly can be flexibly adjusted according to actual washing needs to optimize washing performance. Specifically, four, five, six, or more blades 110 can be provided on the impeller body 100. The blades 110 are evenly distributed along the circumference of the impeller body 100, and the included angles between adjacent blades 110 are 90° (four blades 110), 72° (five blades 110), 60° (six blades 110), or other angles, to ensure that the impeller body 100 generates a balanced and wide-coverage water flow when rotating. One, two, or more rollers 200 can be provided between two adjacent blades 110, and one, two, or more rotating wheels 300 can also be provided on both sides of each roller 200 or at other positions between the blades 110 as needed. The number of rollers 200 and rotating wheels 300 is not specifically limited.

[0051] Optionally, when the impeller body 100 is installed inside the garment processing equipment, such as Figure 5 As shown, the axis of the roller 200 forms a preset angle α with the horizontal plane. This preset angle α is greater than 0° and less than 90°. When the impeller body 100 rotates, the roller 200 tilts the water flow, creating a more complex water flow path. This significantly enhances the three-dimensionality and impact of the water flow, thereby improving the cleaning effect. Optionally, the preset angle α can be 5°, 10°, 15°, 20°, 25°, 30°, 45°, 60°, etc., and the tilt angle of the roller 200 axis can be set according to actual washing needs to achieve the best washing effect.

[0052] Optionally, the roller 200 includes a roller body 210 and a cover 220. The roller body 210 has a hollow portion 212 inside. One end of the roller body 210 has a first shaft portion 211, and the other end has an opening communicating with the hollow portion 212. The cover 220 is connected to the roller body 210 and seals the opening. The end of the cover 220 opposite to the roller body 210 has a second shaft portion 221. The first shaft portion 211 and the second shaft portion 221 are rotatably connected to the two end walls opposite to the first mounting groove 121, respectively. The hollow portion 212 significantly reduces the overall weight of the roller 200, thereby reducing the energy consumption when the impeller body 100 rotates and improving the operating efficiency of the garment processing equipment. At the same time, the detachable connection between the cover 220 and the roller body 210 makes the installation, disassembly, and maintenance of the roller 200 more convenient. If the roller 200 wears down during use, the service life of the impeller assembly can be significantly extended and maintenance costs reduced by replacing the cover 220 and the roller body 210.

[0053] Specifically, such as Figure 2 As shown, the first base 120 has a first circular groove 122 at one end near the center of rotation and a second circular groove 123 at the other end away from the center of rotation. The first shaft portion 211 of the roller 200 is rotatably disposed in the first circular groove 122, and the second shaft portion 221 of the roller 200 is rotatably disposed in the second circular groove 123.

[0054] Optionally, such as Figure 3 As shown, the roller body 210 is provided with a plug-in portion 214, and the plug-in portion 214 is symmetrically provided with a first notch 2141. The cover 220 is provided with a first protrusion 222 corresponding to the first notch 2141. The first protrusion 222 can circumferentially position the assembly position of the cover 220, preventing the cover 220 and the roller body 210 from rotating relative to each other. Furthermore, the plug-in portion 214 is provided with a snap-fit ​​boss 2142, and the cover 220 is provided with a snap-fit ​​groove 223. The cover 220 is fitted onto the plug-in portion 214, and the snap-fit ​​boss 2142 can snap into the snap-fit ​​groove 223, thereby limiting the cover 220 circumferentially around the roller 200 and ensuring the stability of the connection between the cover 220 and the roller body 210. In other embodiments, the cover 220 can be bonded to the roller body 210.

[0055] In other embodiments, the roller 200 is constructed as a single piece, which simplifies the processing of the roller 200, improves the structural strength of the roller 200, and increases the manufacturing efficiency of the roller 200, thereby further saving production costs.

[0056] Optionally, the roller 200 is a frustum-shaped roller or a conical roller. The cross-sectional area of ​​the end of the frustum-shaped roller or the conical roller near the rotation center of the impeller body 100 is smaller than the cross-sectional area of ​​the end of the roller away from the rotation center of the impeller body 100. This reduces the resistance of the water flow inside during washing, promotes the water flow to the outside, and enhances the thrust and impact of the water flow outside, thereby forming a stronger radial and axial composite water flow. This design significantly improves the three-dimensionality and turbulence intensity of the water flow, thereby improving the washing effect.

[0057] In this embodiment, the roller 200 is preferably a frustum-shaped roller. The ratio of the diameter of the end of the frustum-shaped roller near the rotation center of the impeller body 100 to the diameter of the end of the frustum-shaped roller away from the rotation center of the impeller body 100 is between 1:1.5 and 1:2.5, specifically 1:1.6, 1:1.8, 1:2, 1:2.2, 1:2.4, etc.

[0058] In other embodiments, the roller 200 can be a cylindrical roller, which has a simpler structure, is easier to process and manufacture, and improves the production efficiency of the roller 200.

[0059] Optionally, such as Figure 2 As shown, the bottom wall of the first seat 120 is arc-shaped and has multiple first through holes 124. The arc-shaped bottom wall of the first seat 120 can better fit the outer circumference of the roller 200, making the impeller assembly structure more compact and aesthetically pleasing. The multiple first through holes 124 can prevent water accumulation inside the first seat 120 and ensure that water can flow smoothly through the impeller body 100, thereby improving the fluidity of the water flow.

[0060] Optionally, the impeller body 100 has a frustum 140 at its rotation center, and multiple blades 110 are spaced circumferentially along the frustum 140. The height of each blade 110 gradually increases from the end closer to the rotation center of the impeller body 100 to the end farther away from the rotation center. The frustum 140, as a protruding structure at the rotation center, effectively guides the water flow outward from the center, forming a stable radial water flow base, while simultaneously enhancing the structural strength of the impeller body 100, ensuring stability and durability during high-speed rotation. The gradual increase in the height of each blade 110 from the end closer to the rotation center of the impeller body 100 to the end farther away from the rotation center reduces the resistance of the inner water flow and enhances the thrust and impact force of the outer water flow, forming a composite water flow in both radial and vertical directions, thereby further improving the cleaning effect.

[0061] Optionally, a pulsator cover 141 is provided on the frustum portion 140. The pulsator cover 141 is fixedly connected to the frustum portion 140. The pulsator cover 141 is provided with a first protruding rib 1411. The pulsator cover 141 can play an auxiliary stirring role, further improving the washing effect. In addition, a mating groove 142 is provided on the side of the frustum portion 140 away from the pulsator cover 141. The mating groove 142 is sleeved on the output shaft of the drive component, so that the pulsator body 100 is connected to the output shaft of the drive component for transmission. The pulsator cover 141 can play a role in concealing the assembly structure, making the pulsator assembly more aesthetically pleasing as a whole.

[0062] In this embodiment, the impeller cover 141 is snapped onto the frustum portion 140. The impeller cover 141 is provided with a hook, and the frustum portion 140 is provided with a fixing hole. The hook passes through the fixing hole and is snapped onto the frustum portion 140. In other embodiments, the impeller cover 141 can be fixed onto the frustum portion 140 by adhesive or welding.

[0063] Optionally, the impeller body 100 is further provided with a second seat 130, which is located between two adjacent blades 110. The second seat 130 has a mounting surface that is inclined towards the center of rotation, and the axis of the impeller 300 is perpendicular to the mounting surface. Figure 5 and Figure 6 As shown, the mounting surface is inclined towards the center of rotation, so that the axis of the impeller 300 forms an angle β with the axis of the impeller body 100. This inclined arrangement of the impeller 300 can drive the water flow to form a complex water flow when the impeller body 100 rotates, thereby improving the washing effect. Specifically, the angle β between the axis of the impeller 300 and the axis of the impeller body 100 is greater than 0° and less than 90°. The angle β can be 5°, 15°, 20°, 25°, 30°, 45°, 60°, or 75°, and can be flexibly adjusted according to actual washing needs.

[0064] Optionally, one of the second seat 130 and the impeller 300 is provided with a snap-fit ​​part 310, and the other of the second seat 130 and the impeller 300 is provided with a mating part 131. The snap-fit ​​part 310 can snap into the mating part 131, and the impeller 300 can rotate around its own axis, ensuring the positional stability of the impeller 300 when the impeller body 100 rotates at high speed, preventing loosening or displacement, thereby ensuring that the impeller 300 continuously generates a stable turbulent water flow.

[0065] In this embodiment, the snap-fit ​​part 310 is a hook, and the mating part 131 is an assembly hole. The hook includes a connecting shaft part and a hook part. One end of the connecting shaft part is connected to the rotating wheel 300, and the other end is provided with a hook part. The second seat 130 is provided with an assembly hole. During installation, the hook part of the hook is passed through the assembly hole and hooked on the bottom surface of the second seat 130 to prevent the rotating wheel 300 from coming off axially. However, the diameter of the connecting shaft part is smaller than the diameter of the assembly hole, so that the rotating wheel 300 can rotate freely.

[0066] In other embodiments, the snap-fit ​​part 310 can be a mating structure of a pin and a snap ring, and the mating part 131 is a pin hole. By setting a pin hole on the second seat 130 and setting a pin on the rotating shaft, the free end of the pin passes through the pin hole and is axially limited by the snap ring for the rotating wheel 300.

[0067] Optionally, the second seat 130 is provided with a second through hole 132, which allows water to flow freely through the second seat 130 when the impeller body 100 rotates, promoting water exchange and circulation and preventing water accumulation in the second seat 130.

[0068] Example 2

[0069] This embodiment provides a pulsator assembly, which is basically the same as that in Embodiment 1, except that the pulsator assembly in this embodiment includes a pulsator body 100, on which a plurality of blades 110 are protruding. Each blade 110 is arranged at intervals along the circumference of the pulsator body 100. A roller 200 is rotatably disposed on the pulsator body 100. Along the direction from bottom to top, the axis of the roller 200 gradually moves away from the axis of the pulsator body 100. The roller 200 can rotate freely around its own axis. Through the synergistic effect of the blades 110 and the roller 200, multi-directional and multi-layer water flow can be generated when the pulsator body 100 rotates, which significantly improves the impact and tumbling effect of the water flow on the clothes and improves the washing ratio.

[0070] Optionally, the outer wall of the roller body 210 is provided with a plurality of strip-shaped grooves 213 spaced apart along the circumference of the roller body 210, thereby forming a protrusion between two adjacent grooves 213. The alternating structure of the grooves 213 and the protrusions makes the roller 200 generate a moderate friction force with the clothes, effectively pushing the roller 200 to rotate around its own axis, thereby improving the washing effect.

[0071] Optionally, the depth of the groove 213 gradually increases from the end near the rotation center of the impeller body to the end away from the rotation center. The shallower depth of the groove 213 near the rotation center reduces the resistance of the inner water flow, promotes the water flow to the outside of the roller 200, and ensures the uniformity of the initial water flow distribution. The greater depth of the groove 213 away from the rotation center enhances the capture and disturbance ability of the outer water flow, generating stronger local turbulence and eddies, thereby forming a composite water flow in the radial and axial directions. Specifically, the ratio of the depth of the groove 213 near the rotation center to the depth of the groove 213 away from the rotation center is between 1:1.5 and 1:3, specifically 1:1.6, 1:1.8, 1:2, 1:2.2, 1:2.4, 1:2.6, 1:2.8, etc.

[0072] Optionally, the width of the groove 213 gradually increases from the end near the rotation center of the impeller body to the end away from the rotation center. The narrower groove 213 near the rotation center can reduce water flow resistance, while the wider groove 213 away from the rotation center expands the capture and disturbance range of water flow on the outside of the impeller body, enhancing the ability to form local turbulence and eddies, thereby generating a stronger radial and axial composite water flow. Specifically, the ratio of the width of the end of the groove 213 near the rotation center to the width of the end of the groove 213 away from the rotation center is between 1:1.5 and 1:2.5, specifically 1:1.6, 1:1.8, 1:2, 1:2.2, 1:2.4, etc.

[0073] Understandably, during the washing process, due to the centrifugal force, most of the clothes are far from the center of rotation and close to the inner wall of the inner drum of the garment processing equipment. Therefore, the design of the groove 213 on the roller 200, which is far from the center of rotation, with its depth and width gradually increasing, is more in line with the actual washing process, further improving the agitation and cleaning effect on the clothes and thus increasing the washing ratio.

[0074] Example 3

[0075] This embodiment provides a pulsator assembly, which is basically the same as that in Embodiment 1, except that the pulsator assembly includes a pulsator body 100 and a rotating wheel 300. Multiple blades 110 are protruding from the pulsator body 100, and the blades 110 are spaced apart circumferentially around the pulsator body 100. The rotating wheel 300 is rotatably mounted on the pulsator body 100, and its axis gradually approaches the axis of the pulsator body 100 from bottom to top. The rotating wheel 300 can rotate freely around its own axis. Through the synergistic effect of the blades 110 and the rotating wheel 300, multi-directional and multi-layered water flow is generated when the pulsator body 100 rotates, significantly improving the impact and tumbling effect of the water flow on the clothes, increasing the washing ratio. Furthermore, the rotating wheel 300's rotatable mounting on the pulsator body 100 effectively reduces friction between the clothes and the pulsator assembly, significantly reducing wear and tear on the clothes, extending their lifespan, and improving the user experience.

[0076] Optionally, the impeller 300 is provided with a second rib 320, which forms a prominent turbulence structure, enhancing the washing and tumbling effect on clothing. In this embodiment, the impeller 300 is provided with three second ribs 320, which are spaced apart circumferentially along the impeller 300 and converge at the rotation center of the impeller 300 itself, improving the structural strength of the impeller 300 while enhancing the turbulence effect on the water flow.

[0077] Example 4

[0078] This embodiment provides a garment processing device, including a drum assembly and a pulsator assembly as described in any of the above embodiments. The pulsator assembly is disposed inside the drum assembly, and the pulsator assembly increases the agitation and cleaning effect on the garments, significantly improving the washing ratio of the garment processing device.

[0079] For example, taking a washing machine as an example of a clothing handling device, the washing machine includes a housing, a drive motor, a drum assembly, and the pulsator assembly as described in Embodiment 1. The drum assembly includes an inner drum and an outer drum. The outer drum is disposed within the housing, and the inner drum is coaxially disposed within the outer drum. The pulsator assembly is coaxially fixed to the inner drum and located at the bottom of the inner drum. Both the pulsator assembly and the inner drum are connected to the drive motor for transmission. This washing machine can improve the washing effect of clothes and reduce wear and tear on clothes, significantly improving the user experience. In other embodiments, the clothing handling device can also be a washer-dryer combo, etc.
