[0002] Clothes processing devices are devices used to wash, dry, care for clothes and other functions. These devices can remove dust or foreign matter on clothes to ensure the cleanliness and care effect of clothes.

[0003] A washing machine is a type of clothing processing device. It is a cleaning appliance that uses electrical energy to generate mechanical action to wash clothes. Based on their structure and operating principle, washing machines can be divided into two categories: pulsator washing machines and drum washing machines. Among them, pulsator washing machines use the rotation of the impeller at the bottom to drive the water flow, causing the clothes to tumble in the water, thereby achieving the purpose of washing. Due to their large capacity and simple operation, they are widely used. Pulsator washing machines consist of an inner drum (washing tub) and a water channel structure. The inner drum is the core component of the pulsator washing machine. It contains a impeller, which rotates under the drive of the motor, driving the water flow and washing the clothes. The inner drum is usually designed with multiple holes to allow water and detergent to enter and exit. The water channel structure is set in the inner drum and is responsible for introducing and draining water into and out of the washing machine.

[0004] In the related art, the water channel structure is usually designed to be non-detachable, making it difficult for users to clean the gap between the inner tub and the water channel structure.

[0057] See also Figures 1 to 3 The present invention provides a laundry treatment device, which generally refers to a household appliance used for washing, rinsing, and dehydrating clothes, such as a washing machine. It uses mechanical force and water flow, combined with detergent, to remove stains and impurities from clothes, restoring them to a clean state.

[0058] Taking a pulsator washing machine as an example, the laundry processing device comprises a housing and an inner drum assembly 100. The housing is the outer shell of the laundry processing device, typically made of materials such as metal or plastic. It provides a safe and user-friendly external interface. It also provides sound insulation and shock absorption, reducing noise and vibration generated during operation. Furthermore, the housing plays a role in aesthetics and design, being an important component of the product's appearance.

[0059] A accommodating space is formed in the box body, and the inner drum assembly 100 is accommodated in the accommodating space. It is the core part of the clothing processing device. The main function of the inner drum assembly 100 is to accommodate clothes and directly contact the clothes during the washing process, washing the clothes through mechanical force and water flow.

[0060] The inner barrel assembly 100 includes an inner barrel 10, a balance ring 20 and a water channel structure 30, wherein the inner barrel 10 can adopt a non-porous stainless steel inner barrel design, the inner barrel 10 includes a barrel body 11 and a barrel bottom 12 connected to the bottom end of the barrel body 11, the barrel body 11 is annular, the barrel bottom 12 is located at the bottom of the barrel body 11, and the wall of the barrel body 11 is provided with the above-mentioned 3D cubic structure, which effectively avoids the problem of clothes being squeezed into the small holes of the barrel body 11 under the action of centrifugal force during dehydration, and avoids wrinkles, deformation, scratches and tears in clothes. The 3D cubic structure formed on the barrel body 11 has a concave and convex design that can cooperate with the strong beating of water during cleaning to disintegrate stains. In addition, the non-porous stainless steel barrel body 11 is not easy to breed bacteria, which is conducive to keeping clothes clean.

[0061] The balance ring 20 is provided at the top of the drum body 11 away from the drum bottom 12 to improve the stability of the washing process and reduce vibration. In a pulsator washing machine, when the inner drum 10 rotates at high speed for washing or dehydration, the balance ring 20 is used to solve the uneven distribution of clothes, which can cause the center of gravity to shift and generate vibration and noise.

[0062] The water channel structure 30 is disposed within the inner tub 10 and may include a lint filter or a waterfall structure. The lint filter primarily captures and collects fine fibers, hair, and other debris that fall from clothing during the washing process, thereby improving the washing effect. The waterfall structure, on the other hand, generates a powerful water flow, simulating the effect of a waterfall, spraying the water onto the clothing to be washed. This increases friction between the clothing and enhances detergent penetration, thereby improving washing efficiency.

[0063] The water channel structure 30 has a first connection end 30a and a second connection end 30b disposed in opposite directions. The water channel structure 30 has an assembled state and a clean state. In the assembled state, the first connection end 30a is connected to the balance ring 20, which is generally designed to be relatively sturdy. Connecting the first connection end 30a of the water channel structure 30 to the balance ring 20 can enhance the stability of the connection between the water channel structure 30 and the balance ring 20, allowing it to remain fixed during high-speed washing and prevent displacement or damage due to vibration. The second connection end 30b is connected to the bottom 12 of the barrel, that is, the water channel structure 30 has multiple ways of being assembled in the inner barrel 10, allowing the water channel structure 30 to be connected to the bottom 12 of the barrel in different ways, which can be adjusted according to different design and performance requirements.

[0064] In the cleaning state, at least one of the first connection end 30a and the second connection end 30b can be disconnected so that the water channel structure 30 can move relative to the inner barrel 10 to expose the area of ​​the inner barrel 10 that is covered by the water channel structure 30 when in the assembled state, so that users or maintenance personnel can quickly and conveniently perform cleaning and maintenance work, especially for hard-to-reach areas, such as the back of the water channel structure 30 and the gap between the water channel structure 30 and the inner barrel 10, which helps to remove dirt, bacteria and mold accumulated over a long period of time, thereby improving the washing effect of the clothing processing device and the cleanliness of the clothes.

[0065] In one embodiment, the first connection end 30a is detachably connected to the balance ring 20, and the second connection end 30b is movably connected to the bottom 12. The movably connected connection may be a rotational connection, for example, the second connection end 30b is rotatably connected to the inner tub 10. During cleaning, the first connection end 30a is detached from the balance ring 20 to form a free end. The waterway structure 30 can be rotated in a direction toward the central axis of the tub body 11, with the axis of rotation between the second connection end 30b and the inner tub 10 serving as the axis of rotation, thereby exposing the area of ​​the inner tub 10 covered when the waterway structure 30 is assembled. This allows the user to more directly access the area requiring cleaning, clearing the back of the waterway structure 30 and the gap between the waterway structure 30 and the inner tub 10. The detachable and rotatable connection design simplifies maintenance. The user only needs to remove the first connection end 30a of the waterway structure 30 to quickly perform cleaning, without the need for complex operations or specialized tools. It is understood that the movably connected connection between the second connection end 30b and the bottom 12 may also include a sliding connection.

[0066] In another embodiment, the first connecting end 30a is movably connected to the balance ring 20, and the second connecting end 30b is detachably connected to the tub bottom 12. The movable connection may be a sliding connection. For example, the first connecting end 30a is slidably connected to the inner tub 10. When cleaning, the second connecting end 30b is detached from the tub bottom 12 to form a free end. The first connecting end 30a can be slid and withdrawn along the axial direction of the inner tub 10, exposing the area of ​​the inner tub 10 covered when the water channel structure 30 is assembled. The user can more directly access the area that needs to be cleaned, and the user can easily clean the back of the water channel structure 30 and the gap between the water channel structure 30 and the inner tub 10. It is understandable that the movable connection between the first connecting end 30a and the balance ring 20 may also be a rotating connection.

[0067] In another embodiment, the first connecting end 30a is detachably connected to the balance ring 20, and the second connecting end 30b is detachably connected to the barrel bottom 12. Since both the first connecting end 30a and the second connecting end 30b of the water channel structure 30 are detachable to achieve the overall disassembly of the water channel structure 30, the user can thoroughly clean the water channel structure 30 and every corner between the water channel structure 30 and the inner barrel 10, including gaps and backs that are usually difficult to reach, which helps to remove accumulated stains and lint and ensure the hygiene and efficient operation of the washing machine.

[0068] Exemplarily, the detachable connection method between the first connecting end 30a and the balance ring 20 may include at least one of snap-on, plug-in, screw-on, adhesive and magnetic connection, and the detachable connection method between the second connecting end 30b and the barrel bottom 12 may include at least one of snap-on, plug-in, screw-on, adhesive and magnetic connection. This application does not make any specific restrictions on this.

[0069] For ease of understanding, the following describes the specific assembly and disassembly of the waterway structure 30 using an example in which the first connection end 30a is connected to the balance ring 20 by a snap-fit ​​connection, and the second connection end 30b is connected to the barrel bottom 12 by a snap-fit ​​connection. The first and second connection ends 30a, 30b are both assembled using a snap-fit ​​connection. This snap-fit ​​design allows the user to connect and disconnect with a simple manual push or slide action, making assembly and disassembly easy and tool-free, making the entire assembly and disassembly process simple and quick.

[0070] like Figures 4 to 7 As shown, a first clamping member is provided on one of the first connecting end 30a and the balancing ring 20, and a first clamping groove 211 is provided on the other of the first connecting end 30a and the balancing ring 20, and the first clamping member is clamped with the first clamping groove 211. A second clamping member 60 is provided on one of the second connecting end 30b and the bottom 12, and a second clamping groove 1213 is provided on the other of the second connecting end 30b and the inner tub 10, and the second clamping member 60 is clamped with the second clamping groove 1213. This connection method can provide a stable fixing effect, ensuring that during the operation of the pulsator washing machine, the water channel structure 30 can be stably connected to the balancing ring 20 and the inner tub 10, and will not easily loosen or separate, thereby increasing safety during use.

[0071] It should be noted that the barrel bottom 12 includes a barrel base 121 and a pulsator 122 (such as Figure 2 ), the inner bottom wall of the barrel base 121 is recessed to form an assembly groove, and the impeller 122 is arranged on the inner bottom wall of the barrel base 121 and in the assembly groove. The impeller 122 rotates under the drive of the motor to produce a mechanical stirring effect, causing the clothes to turn and stir back and forth in the water to effectively clean the clothes. A plurality of spray holes are provided on the impeller 122, and the water in the outer barrel is pumped into the inner barrel 10 through the spray holes of the impeller 122, so that a water level difference is formed between the inner and outer barrels, which can generate a variety of water flows to wash clothes.

[0072] When the water channel structure 30 is relatively thick, or the impeller 122 can cover the inner bottom wall of the tub base 121, a second clamping member 60 can be provided at one of the second connecting end 30b and the impeller 122, and a second clamping groove 1213 can be provided at the other of the two. It is understood that when the water channel structure 30 is relatively thin, and the diameter of the impeller 122 is smaller than the diameter of the tub base 121, that is, the impeller 122 does not completely cover the inner bottom wall of the tub base 121, a second clamping member 60 can be provided at one of the second connecting end 30b and the tub base 121, and a second clamping groove 1213 can be provided at the other of the two. The second clamping member 60 and the second clamping groove 1213 are engaged with each other. The design of the second clamping member 60 and the second clamping groove 1213 enables quick assembly and disassembly, can withstand repeated assembly and disassembly, is not easily damaged, and improves durability.

[0073] In another embodiment, when the water channel structure 30 is shorter, a second clamping member 60 can be provided at one of the second connecting end 30b and the barrel body 11, and a second clamping groove 1123 can be provided at the other of the second connecting end 30b and the barrel body 11. The second clamping member 60 is clamped with the second clamping groove 1213, so that the water channel structure 30 can be firmly installed on the inner wall of the barrel body 11.

[0074] In addition, at least one of the first and second clips 60 is an elastic clip 50. The elastic clip 50 utilizes its own elasticity to achieve elastic engagement with at least one of the first and second slots 211, 1213. This facilitates engagement and disengagement, and can, to a certain extent, accommodate minor deformations or misalignments between components, i.e., minor installation errors, thereby providing greater flexibility during connection. Furthermore, the elastic clip 50 typically has a self-locking feature. Once inserted into at least one of the first and second slots 211, 1213, it maintains a secure connection, preventing accidental disengagement. This ensures a stable connection of the waterway structure 30 within the inner tub 10, even under the high vibrations experienced during operation of the pulsator washing machine.

[0075] In a specific embodiment, Figures 8 to 10 As shown, a balance ring 20 is provided at the top of the barrel body 11, and the balance ring 20 includes a first clamping portion 21 (as shown in FIG. Figure 7 ), the first engaging portion 21 can be located on the end surface of the balancing ring 20 facing the impeller 122. The first engaging portion 21 has a first engaging groove 211. The elastic engaging member 50 engages with the first engaging groove 211 to achieve an engaging effect between the first connecting end 30a of the water channel structure 30 and the balancing ring 20. Because the first engaging portion 21 is located on the end surface of the balancing ring 20 facing the impeller 122, the first engaging member and the first engaging groove 211 can be connected in a concealed manner, maintaining a neat and aesthetically pleasing appearance of the inner tub 10 assembly.

[0076] See also Figure 10-12 In one possible embodiment, the water channel structure 30 has a slide groove 31, and a first slide groove opening 31a is provided on the first connecting end 30a. The first slide groove opening 31a is formed on the upper end surface of the water channel structure 30, and the first slide groove opening 31a is connected to the slide groove 31. The first clamping member is provided on the first connecting end 30a and is an elastic clamping member 50. At least a portion of the elastic clamping member can be movably passed through the first slide groove opening 31a to lock or unlock the water channel structure 30 and the balance ring 20.

[0077] Specifically, the elastic engaging member 50 includes a snap body 51 and an elastic member 52. The snap body 51 is slidably disposed within the chute 31. Specifically, the snap body 51 is slidable in the axial direction of the inner tub 10 and at least partially extends out of the chute 31 through the first chute opening 31a to engage with the first engaging groove 211. The elastic member 52 is connected to the snap body 51 at one end and to the wall of the chute 31 at the other end. The elastic member 52 tends to move the snap body 51 toward the first engaging groove 211. This arrangement facilitates the snap body 51 to automatically engage with the first engaging groove 211 after alignment with the first engaging groove 211, eliminating the need for the user to manually push the snap body 51 into the first engaging groove 211. Furthermore, the elastic force of the elastic member 52 maintains a tight fit between the snap body 51 and the first engaging groove 211, thereby enhancing the stability of the first connecting end 30a.

[0078] In this embodiment, if Figures 11 to 13 When the user releases the grip, the elastic member 52 applies a force to the sliding portion 511 toward the first slot opening 31a, causing the buckle 512 to pop out of the first slot opening 31a and engage with the first slot 211.

[0079] like Figure 13 As shown, the buckle tongue 512 further has a resisting inclined surface 512a, and the groove wall constituting the first locking groove 211 has a guiding arc surface 211a (as shown in FIG. Figure 5), the guide arc surface 211a is used to abut against the supporting inclined surface 512a when the buckle tongue 512 is inserted into the first slot 211. By setting the guide arc surface 211a, on the one hand, the buckling direction of the buckle tongue 512 can be guided, and the buckle tongue 512 can be helped to be correctly inserted into the first slot 211, thereby reducing the assembly time; on the other hand, the force required for the buckle tongue 512 to be inserted into the first slot 211 can be reduced, thereby reducing the difficulty of inserting the buckle tongue 512.

[0080] like Figure 12 As shown, the buckle body 51 further includes an operating portion 513, which is connected to the sliding portion 511. The operating portion 513 provides a fulcrum, allowing the user to directly push the sliding portion 511 to slide vertically within the chute 31 through the operating portion 513. The chute 31 further includes a second chute opening 31b on the waterway structure 30. The second chute opening 31b can be opened on a side of the waterway structure 30 facing away from the barrel body 11. The operating portion 513 can be slidably disposed in the second chute opening 31b and exposed outside the waterway structure 30, so that the operating portion 513 is located in a position that is easily accessible to the user, facilitating direct sliding operation by the user.

[0081] The operating portion 513 has a plurality of sliding protrusions arranged at intervals. The sliding protrusions can increase the friction between the hand and the operating portion 513, making the sliding operation more stable and reducing the possibility of the user's hand slipping during operation.

[0082] like Figure 13 As shown, further, the buckle body 51 also includes a sleeve shaft 514, which is connected to the sliding part 511 and extends in the direction away from the buckle tongue 512; wherein, the elastic member 52 includes a spring, one end of the spring is sleeved on the sleeve shaft 514, and the other end of the spring abuts against the groove wall of the slide groove 31. The setting of the sleeve shaft 514 provides a connection and guiding function for the spring, so that the user can slide the buckle body 51 along the axial direction of the inner barrel 10, so that the buckle tongue 512 is easier to get into or out of the first slot 211, and the sliding is smoother, more stable during operation, and unnecessary shaking or displacement is reduced.

[0083] Compared to other non-spring elastic structures, such as shrapnel, the spring's helical shape makes it easier to install on the sleeve shaft 514. The spring's manufacturing process is relatively simple, allowing for mass production and, therefore, lowering costs. The spring maintains a relatively constant spring constant under load. The spring material also has a long fatigue life and can withstand repeated compression without breaking. Its compact structure allows it to provide the required elastic force within a limited space.

[0084] Please continue reading Figure 11-13The water channel structure 30 is connected to the first connection end 30a of the auxiliary water channel structure 30. The water channel structure 30 includes a front water channel cover 32, a rear water channel cover 33, and a chute 34. The rear water channel cover 33 is disposed opposite the tub body 11 and covers the rear water channel cover 33 in the direction toward the impeller 122. The rear water channel cover 33 and the rear water channel cover 33 are connected to form a water channel, which can be used for water inlet and outlet. The chute 34 is connected to the front water channel cover 32 and can be specifically disposed above the rear water channel cover 33. Together with the front water channel cover 32, it forms a chute 31. The chute 34 and the front water channel cover 32 protect the internal elastic clip 50 from foreign objects such as clothing that could affect the engagement of the elastic clip 50. Furthermore, when operating the connection between the elastic clip 50 and the balance ring 20, the user does not need to reach into the bottom of the inner tub 10, thereby simplifying the operation process and improving the convenience of operation.

[0085] The water channel front cover 32 is provided with a positioning protrusion 321 and a positioning groove 212 (such as Figure 5 ), the first connection end 30a is provided with a positioning protrusion 321 and the other of the positioning grooves 212, the positioning protrusion 321 can be embedded in the positioning groove 212, and in the process of the first clamping member being clamped into the first clamping groove 211, the positioning protrusion 321 and the positioning groove 212 can guide the first clamping member to be clamped into the first clamping groove 211, and can provide a positioning effect for the connection between the first connection end 30a of the water channel structure 30 and the balance ring 20. In addition, the positioning protrusion 321 and the positioning groove 212 can limit each other in the circumferential direction of the balance ring 20, and also increase the connection stability between the first connection end 30a and the balance ring 20, and reduce the displacement or falling off of the water channel structure 30 due to external vibration or impact.

[0086] In one embodiment, if Figure 11 As shown, the positioning protrusion 321 is provided on the waterway front cover 32. Figure 7 As shown, a positioning groove 212 is provided on the first engaging portion 21 of the balancing ring 20. Multiple positioning grooves 212 may be provided, and along the circumference of the balancing ring 20, multiple positioning grooves 212 are located on opposite sides of the first engaging groove 211. Positioning protrusions 321 are provided in a one-to-one correspondence with the positioning grooves 212. The provision of multiple positioning protrusions 321 and multiple positioning grooves 212 provides more positioning and connection positions, thereby enhancing the stability of the connection between the waterway structure 30 and the balancing ring 20.

[0087] like Figure 5 or Figure 7As shown, there are two positioning grooves 212 in this embodiment, and the two positioning grooves 212 are arranged on opposite sides of the first card groove 211 along the circumference of the balance ring 20. During assembly, the two positioning protrusions 321 on the water channel front cover 32 can be respectively embedded in the corresponding positioning grooves 212, so that the water channel structure 30 and the balance ring 20 form a preliminary positioning, which facilitates the subsequent elastic clip 50 to form a stable connection.

[0088] Following the above embodiment, Figure 4 and Figure 6 As shown, the connection method of the second connection end 30b of the water channel structure 30 is as follows. The barrel base 121 includes a second clamping portion 1211, which has a second clamping groove 1213. The outer diameter of the impeller 122 can be set to be smaller than the inner diameter of the barrel bottom 12. When the impeller 122 is installed on the barrel bottom 12, a portion of the barrel bottom 12 is exposed between the outer periphery of the impeller 122 and the edge of the barrel bottom 12, forming an annular mounting portion. This provides additional space for the assembly of the water channel structure 30 and optimizes the utilization of the internal space of the inner cylinder assembly 100. The annular mounting portion has a second clamping portion 1211, which has a second clamping groove 1213. The second clamping member 60 is engaged with the second clamping groove 1213 to achieve a clamping effect on the second connection end 30b of the water channel structure 30 and the barrel bottom 12.

[0089] In one possible embodiment, the second clamping member 60 is connected to the second clamping slot 1213 by plugging, and the second clamping portion 1211 includes an arc-shaped ridge 1212, which serves as a partial groove wall of the second clamping slot 1213, and the second clamping member 60 includes an inserting portion 61 and an abutting portion 62, and the inserting portion 61 is used to be inserted into the second clamping slot 1213; the abutting portion 62 is connected to the inserting portion 61 and abuts against the arc-shaped ridge 1212.

[0090] In actual use, when in the assembly state, the user first inserts the plug-in portion 61 of the second connection end 30b of the water channel structure 30 into the second card groove 1213, and makes the abutting portion abut against the arc-shaped ridge 1212, and then slides the operating portion 513 exposed in the second slide slot opening 31b, so that the buckle tongue 512 retracts into the first slide slot opening 31a, and then inserts the positioning protrusion 321 into the positioning groove 212 on the balance ring 20, so that the first connection end 30a of the water channel structure 30 is initially positioned. At this time, the first slide slot opening 31a is aligned with the first card groove 211, and the sliding of the operating portion 513 is released, so that the buckle tongue 51 The first chute opening 31a pops out and extends into the first latching groove 211 to form a latching connection, thereby assembling the water channel structure 30 into the inner tub 10. In the cleaning state, the user first slides the operating portion 513 in the second chute opening 31b toward the impeller 122 to retract the latching tongue 512 into the first chute opening 31a, thereby releasing the latching relationship between the latching tongue 512 and the first latching groove 211. The user then pulls the positioning protrusion 321 out of the positioning groove 212 and pulls the water channel structure 30 upward to release the connection between the plug-in portion 61 of the second connecting end 30b and the second latching groove 1213, thereby completely disassembling the water channel structure 30.

[0091] In other settings, such as Figures 14 to 16 As shown, the second connecting end 30b of the water channel structure 30 can also be assembled by connecting to the barrel body 11, specifically as follows: the barrel body 11 has a second card groove 1213 that passes through the barrel body 11; the second clamping member 60 includes a connecting portion 63 and a limiting portion 64, and the second clamping member 60 can be specifically arranged on the side of the water channel back cover 33 facing the barrel body 11, and the connecting portion 63 is passed through the second card groove 1213, and the second card groove 1213 provides support for the connecting portion 63. The second card groove 1213 can be exemplarily a rectangular groove, and the size and shape of the connecting portion 63 are adapted to the rectangular groove, and the rectangular groove can limit the circumferential and axial movement of the connecting portion 63 in the inner barrel 10; the limiting portion 64 is connected to the connecting portion 63, and is located outside the barrel body 11, and is at least partially arranged relative to the outer surface of the barrel body 11, which can limit the radial movement of the water channel structure 30 along the inner barrel 10, so that the second connecting end 30b of the water channel structure 30 is firmly hung on the barrel body 11. It is understandable that the second slot 1213 may not be set through the barrel body 11, and another structural member may be provided inside the barrel body 11 to form the second slot 1213.

[0092] Please continue Figures 14 and 15To position the first connection end 30a of the water channel structure 30 during assembly, the barrel body 11 further includes a positioning hole 111. In the axial direction of the inner barrel 10 assembly, the positioning hole 111 is closer to the first slot 211 than the second slot 1213. The water channel structure 30 also includes a positioning portion 35, which can be specifically disposed on the side of the water channel rear cover 33 facing the barrel body 11. The positioning portion 35 is inserted into the positioning hole 111. On the one hand, the positioning portion 35 inserted into the positioning hole 111 can provide additional support for the water channel structure 30, thereby enhancing the stability of the connection between the water channel structure 30 and the barrel body 11. On the other hand, the user can easily align the water channel structure 30 with the barrel body 11 and perform a preliminary connection by assembling the positioning portion 35 with the positioning hole 111, so that the water channel structure 30 is located in the accurate pre-installation position, facilitating the subsequent connection of the first connection end 30a with the balance ring 20.

[0093] In actual use, when in the assembly state, the user first inserts the connecting portion 63 and the limiting portion 64 at the lower end of the water channel structure 30 into the second card groove 1213, and after the second connecting end 30b is connected to the barrel body 11, the positioning portion 35 is embedded in the direction of the positioning hole 111 and the elastic clamping member 50 is slid to assemble it with the first card groove 211 on the balance ring 20 (or, as shown in FIG. Figure 14 and Figure 15 As shown, in other embodiments, the first slot 211 can also be provided on the barrel body 11, and the elastic clip 50 is assembled with the first slot 211 of the barrel body 11), so that the water channel structure 30 is assembled in the inner barrel 10; in the cleaning state, the elastic clip 50 is first released from the first slot 211 of the balance ring 20, and the water channel structure 30 is flipped in the direction toward the impeller 122, so that the positioning portion 35 is disconnected from the positioning hole 111, and then the second connection end 30b of the water channel structure 30 is pulled upward, so that the limiting portion 64 is no longer arranged opposite to the barrel body 11 and is pulled out from the second slot 1213, thereby releasing the connection state of the second connection end 30b of the water channel structure 30, and realizing the complete disassembly of the water channel structure 30.

[0094] In some settings, two water channel structures 30 are provided, and the two water channel structures 30 are evenly distributed along the circumference of the inner barrel 10. The two water channel structures 30 can be a lint filtering structure and a waterfall structure respectively, which can provide diverse washing functions.

[0095] In another setting form, there are four water channel structures 30, and the four water channel structures 30 can be two lint filtering structures and two waterfall structures respectively. The four water channel structures 30 are evenly distributed along the circumference of the inner barrel 10, that is, the angle between two adjacent water channel structures 30 is 90 degrees, and the two lint filtering structures and the two waterfall structures are alternately arranged. The four evenly arranged water channel structures 30, on the one hand, help the inner drum assembly 100 to maintain the balance of the inner barrel 10 during the washing process and reduce vibration and noise. On the other hand, it realizes the functional diversification of the pulsator washing machine and enhances the overall performance of the pulsator washing machine.

[0096] In the above embodiment, the water channel structure 30 is used as a universal component, and the balance ring 20 and the inner barrel 10 are both provided with structures adapted thereto, making it more convenient to replace components during maintenance, thereby reducing maintenance time and costs. Universal components can be mass-produced, reducing the cost of individual parts, and thus reducing overall manufacturing costs. Moreover, through different universal components, components can be combined as needed to achieve different functions, such as the lint filtering function or the waterfall function mentioned above. Due to the consistency and universality of the assembly relationship between the water channel structure 30 and the inner barrel 10, there is no need to open a new inner barrel 10 to assemble different water channel structures 30, thus avoiding unnecessary financial expenditure. This embodiment enables the water channel structure 30 to meet different waterway function requirements and cater to diverse market demands.

[0097] The inner drum assembly 100 may also include a connecting plate 40 arranged on the outer bottom wall of the inner drum 10. The connecting plate 40 serves as a reinforcing structure and is fixed to the bottom of the inner drum 10, which helps to withstand the force and pressure generated during the washing process, reduce the vibration and displacement of the inner drum 10, and thus improve the stability of the washing process.

[0098] The above description is only a preferred embodiment of the present application and does not limit the patent scope of the present application. All equivalent structural transformations made based on the contents of the present application specification and drawings, or direct / indirect application in other related technical fields, are included in the patent protection scope of the present application.
