Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] In the description of this application, unless otherwise expressly 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 utility model based on the specific circumstances.

[0033] In this application, unless otherwise expressly 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 being 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 being 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.

[0034] In existing technologies, some washing machines or washer-dryer combos employ a multi-component splicing design for their inner drum structure to improve assembly efficiency. For example, Chinese patent CN216274827U discloses a washing machine inner drum and washing machine, which uses a receiving groove on a fixing frame to achieve an embedded connection between the bottom side wall of the drum and the drum body. However, this type of structure has certain technical drawbacks: due to assembly tolerances, gaps can easily form at the connection points between the bottom side wall of the drum, the drum body, and the fixing frame, becoming areas where dirt and detergent residue can accumulate. Moreover, over time, this can potentially cause secondary pollution to clothes during the washing process, affecting the washing effect and the hygiene of the clothes.

[0035] To overcome the above technical problems, such as Figures 1-4 As shown, this embodiment provides an inner drum for a washer-dryer combo, comprising:

[0036] The base frame 1 has a wheel-shaped structure, including a hub 11, spokes 12 and a rim 13, wherein the spokes 12 are connected between the hub 11 and the rim 13;

[0037] The bottom of the cylinder body 2 is fitted onto the outer periphery of the wheel rim 13, and a sealing ring 5 is provided to fill the joint between the cylinder body 2 and the wheel rim 13;

[0038] A bottom plate 3 is installed on the bottom side of the bottom frame 1, and a first sealing gasket 6 is provided between the bottom plate 3 and the bottom frame 1 to fill the splicing gap between them.

[0039] In this embodiment, the cylinder base frame 1, cylinder body 2, and cylinder bottom plate 3 are designed separately, which facilitates individual manufacturing and assembly. At the same time, the tolerances are compensated by the sealing ring 5 and the gasket, reducing the cost of precision machining.

[0040] Preferably, the drum base 1 is an injection-molded part, which makes it easier to manufacture complex structures. The drum body 2 and the drum base plate 3 are thin metal sheets, which have the advantages of high strength, small thickness, and small space occupation. The drum base plate 3 is installed on the bottom side of the drum base 1, which is equivalent to the spokes 12 of the drum base 1 being set on the inner side of the inner drum. The spokes 12 are equivalent to the spaced protrusions set on the inner side of the inner drum. This allows the spokes 12 to push the clothes to rotate with the inner drum during use, optimizing the washing effect.

[0041] The hub 11, spokes 12, and rim 13 form a wheel-like structure. The optimized mechanical distribution of the spokes 12 improves the load-bearing capacity of the inner drum, reducing the risk of vibration deformation during high-speed spin-drying or drying. A sealing ring 5 is installed at the joint between the drum body 2 and the rim 13, and a first sealing gasket 6 is added between the drum bottom plate 3 and the drum base frame 1. This double sealing measure effectively fills the gaps at the corners caused by assembly tolerances, blocking the accumulation of detergent, dirt, fibers, and other residues. This effectively reduces the problem of secondary pollution of clothes caused by the accumulation of dirt in the gaps of traditional spliced ​​structures, improving washing hygiene, and is especially suitable for sensitive clothes or scenarios with high hygiene requirements.

[0042] In one embodiment, combined with Figure 1 , Figure 3 and Figure 5 The outer periphery of the top wall of the wheel rim 13 is provided with a first annular groove 131. The sealing ring 5 includes a first rubber ring 51, which is fixed to the first annular groove 131 and simultaneously adheres to the inner wall of the cylinder body 2 and the wheel rim 13.

[0043] In this embodiment, the first annular groove 131 provides a precise installation reference for the sealing ring 5, preventing the ring from shifting during high-speed rotation or vibration, and ensuring that the sealing surface is always aligned with the gap area. The first ring 51 is also tightly attached to the inner wall of the cylinder body 2 and the outer wall of the wheel rim 13, forming a bidirectional compression seal. Even if there are assembly tolerances or slight deformations, the ring can elastically and adaptively fill the gaps, effectively blocking the path of dirt and other contaminants into the joint.

[0044] Preferably, an inlaid concave-convex structure is provided on the inner wall of the first annular groove 131 corresponding to the first rubber ring 51 to ensure the stability of the first rubber ring 51 during installation.

[0045] In one embodiment, reference is made to Figure 2 and Figure 8The outer periphery of the bottom of the wheel rim 13 is provided with a radially outward protruding limiting ring 132, and the top surface of the limiting ring 132 is provided with a second annular groove 133. The bottom of the cylinder body 2 abuts against the limiting ring 132. The sealing ring 5 includes a second sealing ring 52, which is fixed to the second annular groove 133 and simultaneously adheres tightly to the outer wall of the cylinder body 2 and the limiting ring 132.

[0046] The bottom of the drum body 2 abuts against the top surface of the limiting ring 132, meaning the limiting ring 132 forms an axial hard stop for the installation of the drum body 2. This ensures that the assembly position of the drum body 2 and the wheel rim 13 is precise and controllable, preventing the drum body 2 from sinking or swaying due to vibration or load changes. The second rubber ring 52 is located between the outer wall of the drum body 2 and the limiting ring 132, forming a two-way clamping seal with the inner first rubber ring 51, effectively sealing the mating gaps between the inner and outer sides of the drum body 2 and the drum base frame 1, preventing washing water, fibers, and dirt from entering the gaps from the inner and outer sides.

[0047] Preferably, an inlaid concave-convex structure is provided on the inner wall of the second annular groove 133 corresponding to the second rubber ring 52 to ensure the stability of the second rubber ring 52 installation.

[0048] In one embodiment, the outer peripheral wall of the wheel rim 13 is provided with a plurality of first threaded holes, and the cylinder body 2 is provided with a corresponding first connecting hole. The first bolt 8 passes through the first connecting hole and is threadedly connected to the first threaded hole to fix the cylinder body 2.

[0049] Multiple first threaded holes are evenly distributed along the outer circumference of the wheel rim 13 and are fastened with first bolts 8 to ensure uniform pressure at the connection point between the cylinder body 2 and the wheel rim 13. The bolt connection forms a rigid anchor, which effectively ensures a reliable connection between the cylinder body 2 and the cylinder base frame 1. At the same time, it can avoid local stress concentration and reduce the risk of deformation caused by vibration during high-speed dehydration or drying.

[0050] Furthermore, the cylinder body 2 and the wheel rim 13 are aligned via threaded holes and connecting holes. Bolts, as standardized fasteners, simplify the assembly process, reduce human error, and are suitable for automated production lines. If the sealing ring 5 needs to be replaced or the cylinder body 2 needs to be repaired, the components can be separated simply by removing the bolts, without any destructive operations, significantly reducing maintenance costs and time.

[0051] In one embodiment, a first flexible washer 81 is provided between the nut of the first bolt 8 and the cylinder body 2.

[0052] After the first flexible washer 81 is deformed under pressure, it fills the microscopic uneven gap between the nut and the cylinder 2, preventing water stains and dirt from seeping into the bolt hole. In addition, the first flexible washer 81 can absorb the vibration energy generated during the washing and drying process, reduce the preload attenuation of the bolt due to long-term alternating load, and prevent the connection from loosening.

[0053] In one embodiment, combined with Figure 6 and Figure 9 The spoke 12 has a hollow groove 121 on its bottom side, and a connecting post 122 is provided in the hollow groove 121. The connecting post 122 has a second threaded hole. The bottom plate 3 has a corresponding second connecting hole. The second bolt 9 passes through the second connecting hole and the first sealing gasket 6 and is threaded into the second threaded hole to fix the bottom plate 3.

[0054] The hollow groove 121 on the bottom side of the spoke 12 can reduce the weight and material consumption of the base frame 1, and at the same time reduce the mating area between the base frame 1 and the base plate 3, making it easier to improve the mating accuracy between the base frame 1 and the base plate 3, so that the two can tightly clamp the first sealing gasket 6 and improve the sealing performance.

[0055] The second bolt 9 is used to fasten the bottom plate 3 to the bottom frame 1. The bolt connection forms a rigid anchor, which effectively ensures the reliable connection between the bottom plate 3 and the bottom frame 1.

[0056] In one embodiment, reference is made to Figures 6-7 It also includes a fixed tailstock 4, which has a through hole corresponding to the second threaded hole. The fixed tailstock 4 is located on the bottom side of the cylinder bottom plate 3. The second bolt 9 passes through the through hole, the second connecting hole, and the first sealing gasket 6 and is threaded to the second threaded hole.

[0057] The tail fixing bracket is provided, which can cooperate with the bottom frame 1 to clamp the bottom plate 3, thereby achieving reliable fixation of the thin bottom plate 3 and preventing the bottom plate 3 from deforming during use.

[0058] Preferably, the tail fixing frame is an injection molded structure.

[0059] In one embodiment, a second sealing gasket 7 is provided between the fixed tail frame 4 and the bottom plate 3 to fill the splicing gap between the two.

[0060] Similarly, a second sealing gasket 7 is provided between the tail fixing frame and the bottom plate 3 to fill the joint gap between the two, which can prevent dirt from entering and being stored in the joint gap.

[0061] In one embodiment, the fixed tailstock 4 includes a central ring 41 and a plurality of clamping arms 42 connected to the outer periphery of the central ring 41. The clamping arms 42 correspond one-to-one with the spokes 12, and the through holes are provided on the clamping arms 42.

[0062] By configuring the tail fixing bracket as a central ring 41 and clamping arms 42 connected in a star-shaped pattern around the central ring 41, it can both cooperate with the bottom frame 1 to clamp the bottom plate 3, and has the advantages of being lightweight and requiring less material. In addition, it can also avoid the problem of the tail fixing bracket blocking the water leakage holes on the bottom plate 3.

[0063] In one embodiment, a second flexible washer 91 is provided between the nut of the second bolt 9 and the fixed tail bracket 4.

[0064] Similarly, after the second flexible washer 91 is deformed under pressure, it fills the microscopic uneven gap between the nut and the fixed tail bracket 4, preventing water stains and dirt from seeping into the bolt hole. In addition, the second flexible washer 91 can absorb the vibration energy generated during the washing and drying process, reduce the preload attenuation of the bolt due to long-term alternating load, and prevent the connection from loosening.
