[0014] In some embodiments of this invention, the mounting hole is configured as a blind hole.

[0015] In some embodiments of this utility model, the mounting hole includes a countersunk hole and a threaded hole. The countersunk hole is used to mate with a countersunk groove on the inner tub, and the threaded hole is recessed from the bottom of the countersunk hole into the inner cavity of the integral body.

[0016] In some embodiments of this utility model, the opening edge of the countersunk hole forms an arc surface with the mounting surface, and / or,

[0017] The countersunk hole forms an arc surface between the bottom of the groove and the sidewall.

[0018] In some embodiments of this invention, the positioning groove is configured to transition fit or interference fit with the corresponding positioning protrusion on the inner barrel; and / or,

[0019] The mounting hole is configured to transition fit or interference fit with the countersunk groove on the inner tub.

[0020] According to a second aspect of this utility model, an inner tub assembly is also provided, comprising:

[0022] In some embodiments of this utility model, the countersunk groove and the positioning protrusion are respectively recessed inward from the side wall of the inner barrel, the countersunk groove is configured to fit the countersunk hole of the mounting hole, and the positioning protrusion is configured to fit the corresponding positioning groove.

[0023] According to a third aspect of the present invention, a garment processing device is also provided, including the aforementioned inner tub assembly.

[0024] Compared with the prior art, the advantages and positive effects of this utility model are:

[0025] The integrated lifting rib provided by this utility model is fixedly connected to the inner drum of the garment processing equipment by mounting fasteners through mounting holes. The positioning grooves on both sides of the mounting holes cooperate with the positioning protrusions on the inner drum, making assembly simple and convenient, simplifying the assembly process, reducing assembly parts, and thus reducing production costs.

[0052] Wherever possible, the various aspects and features described and illustrated in this specification may be applied individually, and these individual aspects may serve as the subject matter of a divisional application.

[0053] This utility model provides an integrated lifting rib for installation on the inner drum 10 of a garment processing device.

[0054] like Figures 1 to 6 As shown, the integrated lifting rib includes an integrated body 20, which forms a hollow inner cavity, and also includes a mounting surface 21 formed on the outer side of the integrated body 20, which is used to abut against the inner wall of the inner barrel 10.

[0055] The mounting surface 21 is provided with at least one mounting hole 22 and at least one positioning groove 23. The mounting hole 22 is used to install fasteners 30. The integrated body 20 is fixedly connected to the inner barrel 10 by fasteners 30.

[0056] The inner tub 10 is provided with a positioning protrusion 12, and the positioning groove 23 is used to cooperate with the positioning protrusion 12 on the inner tub 10. Specifically, the inner tub 10 is provided with at least one positioning protrusion 12, and the positioning groove 23 corresponds one-to-one with the positioning protrusion 12.

[0057] The mounting holes 22 and the positioning grooves 23 are arranged along the length of the integral body 20. The mounting holes 22 and the positioning grooves 23 are recessed into the interior of the integral body 20 from the mounting surface 21.

[0058] The unibody 20 is manufactured using a one-piece molding process, such as blow molding, injection molding, or 3D printing. The unibody 20 has a single, integrated structure, resulting in high production efficiency, better quality, and higher reliability. It also reduces seams, thus minimizing the problem of dirt and grime accumulating in gaps.

[0059] The integrated main body 20 is connected to the inner barrel 10 by fasteners 30 installed through mounting holes 22. Fasteners 30 can be bolts or screws, making assembly simple and convenient.

[0060] The positioning groove 23 cooperates with the positioning protrusion 12 on the inner barrel 10 to help the fastener 30 fix the position of the integrated body 20, improve the installation stability of the integrated body 20, and prevent shaking. In addition, the positioning groove 23 can share the force of the fastener 30, thereby improving the stability of the fastener 30.

[0061] The positioning groove 23 can also be used to position the integrated main body 20 during installation, making assembly more convenient. During installation, after the positioning groove 23 mates with the corresponding positioning protrusion 12, the mounting hole 22 can be aligned with the through hole on the inner barrel 10 for fasteners 30, allowing the fasteners 30 to be inserted directly. This simple and convenient installation saves assembly time and improves production efficiency.

[0062] The mounting surface 21 is attached to the inner wall of the inner tub 10, which can hide the mounting hole 22 and the positioning groove 23, making it difficult for water and dirt to enter the mounting hole 22 and the positioning groove 23, thus helping to reduce the problem of dirt accumulation.

[0063] The mounting hole 22 is constructed as a blind hole to prevent water from entering the interior of the one-piece body 20.

[0064] Furthermore, the integrated body 20 is constructed as a closed structure, and the mounting holes 22 and positioning grooves 23 are not connected to the inner cavity of the integrated body 20, so as to prevent external water, dirt and other substances from entering the inner cavity of the integrated body 20 and causing the problem of dirt and grime to accumulate inside the integrated body 20.

[0065] The mounting surface 21 is in contact with the inner wall of the inner tub 10. The mounting surface 21 can be set as an arc surface that fits the inner tub 10, which can reduce the gap between the mounting surface 21 and the inner tub 10, preventing lint and other debris from entering and thus making it less likely to accumulate dirt.

[0066] The mounting holes 22 and positioning grooves 23 are spaced apart from the edge of the mounting surface 21, allowing the edge of the mounting surface 21 to better fit the inner tub 10, thus hiding the mounting holes 22 and positioning grooves 23 and preventing water and dirt from entering.

[0067] The integrated body 20 is a long strip structure that extends basically along the axis of the inner tub 10. During the operation of the garment processing equipment, the integrated body 20 experiences significant radial forces, and the forces at both ends of the integrated body 20 are usually different. The mounting holes 22 and positioning grooves 23 are arranged on opposite sides of the mounting holes 22 along the length of the integrated body 20, which can enhance the stability of the integrated body 20, prevent the integrated body 20 from shaking, and also improve the stability of the fasteners 30, making the fasteners 30 less prone to loosening.

[0068] In some embodiments, multiple positioning grooves 23 are provided and arranged on opposite sides of the mounting hole 22, which can position the opposite ends of the integrated body 20 and further enhance the stability of the position of the two ends of the integrated body 20.

[0069] In one embodiment, the mounting surface 21 has a mounting hole 22 and two positioning grooves 23, and the integral body 20 is fixedly connected to the inner tub 10 by a fastener 30. The inner tub 10 has two corresponding positioning protrusions 12. The two positioning grooves 23 are arranged along the length of the integral body 20 on opposite sides of the mounting hole 22.

[0070] The integrated main body 20 can be securely connected to the inner tub 10 by installing a fastener 30 through the mounting hole 22, making assembly simpler and more convenient. It simplifies the assembly process, reduces assembly parts, and thus reduces production costs; in addition, it creates fewer gaps, thereby reducing hard-to-clean areas.

[0071] In one specific embodiment, the mounting surface 21 is provided with two mounting holes 22 and two positioning grooves 23. The two positioning grooves 23 are respectively close to the opposite ends of the integral body 20, and the two mounting holes 22 are close to the middle of the integral body 20.

[0072] In one specific embodiment, the mounting surface 21 has a mounting hole 22 and four positioning grooves 23. The inner barrel 10 has four corresponding positioning protrusions 12. The four positioning grooves 23 are arranged on opposite sides of the mounting hole 22 along the length of the integral body 20, with two positioning grooves 23 located on the left side of the integral body 20 and the other two positioning grooves 23 located on the right side of the integral body 20.

[0073] In some implementations, such as Figure 1 As shown, the positioning groove 23 extends along the length of the integral body 20. Extending the length of the positioning groove 23 helps to improve the structural strength of the positioning groove 23.

[0074] In some implementations, such as Figure 1 and Figure 2 As shown, the groove opening of the positioning groove 23 and the mounting surface 21 can form an arc surface, and the inner wall of the positioning groove 23 and the mounting surface 21 are transitioned through the arc surface. During installation, the positioning protrusion 12 on the inner barrel 10 can more easily be inserted into the positioning groove 23, thus making the installation more convenient.

[0075] In some implementations, such as Figure 1 and Figure 2 As shown, the bottom and sidewall of the positioning groove 23 can form an arc surface, through which a transition is achieved. This avoids the formation of hard-to-clean inner corners within the positioning groove 23, reducing the difficulty of cleaning.

[0076] The inner tub 10 is provided with a countersunk groove 11, which is recessed from the outer side of the inner tub 10 sidewall inward, forming a raised structure on the inner wall of the inner tub 10. The bottom of the countersunk groove 11 is provided with a through hole for fastener 30 to pass through. The fastener 30 passes through the through hole at the bottom of the countersunk groove 11 and connects with the mounting hole 22 on the integral body 20, and the head of the fastener 30 can fit in the countersunk groove 11.

[0077] In some implementations, such as Figure 1 , Figure 2 and Figure 3 As shown, the mounting hole 22 includes a countersunk hole 221 and a threaded hole 222. The countersunk hole 221 is used to mate with the countersunk groove 11 on the inner tub 10, and the threaded hole 222 is recessed from the bottom of the countersunk hole 221 into the inner cavity of the integral body 20 and is provided with internal threads. The fastener 30 is threadedly connected in the threaded hole 222.

[0078] Specifically, the threaded hole 222 and the through hole at the bottom of the countersunk groove 11 are aligned. The countersunk groove 11 and the countersunk hole 221 can also play a role in installation and positioning, so that the threaded hole 222 and the countersunk groove 11 are aligned.

[0079] In some implementations, such as Figure 1 and Figure 2 As shown, the opening edge of the countersunk hole 221 forms an arc surface with the mounting surface 21, and the inner wall of the countersunk hole 221 and the mounting surface 21 transition through the arc surface. During installation, the countersunk groove 11 on the inner barrel 10 can be more easily inserted into the countersunk hole 221, thus making installation more convenient.

[0080] In some implementations, such as Figure 1 and Figure 2 As shown, an arc surface is formed between the bottom of the countersunk hole 221 and its sidewall, providing a smooth transition. This avoids the formation of hard-to-clean inner corners within the countersunk hole 221, reducing the difficulty of cleaning.

[0081] In some implementations, such as Figure 4 As shown, the positioning groove 23 is configured to either transition fit or interference fit with the corresponding positioning protrusion 12 on the inner tub 10. This helps ensure the stability of the connection and also reduces the gap between the positioning groove 23 and the positioning protrusion 12, thereby reducing the accumulation of dirt and grime.

[0082] In some implementations, such as Figure 4 As shown, the mounting hole 22 is configured to transition fit or interference fit with the countersunk groove 11 on the inner tub 10. Specifically, the transition fit or interference fit between the countersunk hole 221 and the countersunk groove 11 helps to ensure the stability of the connection and also reduces the gap between the countersunk hole 221 and the countersunk groove 11, thereby reducing the accumulation of dirt and grime.

[0083] This utility model also provides an inner tub assembly, such as... Figures 3 to 6 As shown, it includes an inner barrel 10, the aforementioned integrated lifting rib, and fasteners 30.

[0084] The integrated lifting rib includes an integrated body 20 with a hollow inner cavity, and a mounting surface 21 formed on the outer side of the integrated body 20. The mounting surface 21 is used to abut against the inner wall of the inner tub 10. The mounting surface 21 has at least one mounting hole 22 and at least one positioning groove 23. The mounting hole 22 is used to install a fastener 30, and the integrated body 20 is fixedly connected to the inner tub 10 by the fastener 30. At least one integrated lifting rib is installed on the inner tub 10.

[0085] The inner tub 10 has a countersunk groove 11 and a positioning protrusion 12 on its side wall. The countersunk groove 11 is used to mate with the mounting hole 22 of the integrated lifting rib, and the positioning protrusion 12 is used to mate with the positioning groove 23 of the integrated lifting rib. The countersunk groove 11 and the positioning protrusion 12 are recessed inward from the side wall of the inner tub 10. The fastener 30 passes through the countersunk groove 11 and is fixedly connected in the mounting hole 22, thus fixing the integrated lifting rib to the inner tub 10.

[0086] Furthermore, the mounting hole 22 includes a countersunk hole 221 and a threaded hole 222. The countersunk hole 221 is used to mate with the countersunk groove 11 on the inner barrel 10, and the threaded hole 222 is recessed from the bottom of the countersunk hole 221 into the inner cavity of the integral body 20 and is provided with internal threads. The fastener 30 is threadedly connected in the threaded hole 222.

[0087] The countersunk groove 11 is configured to fit the countersunk hole 221 of the mounting hole 22, and the positioning protrusion 12 is configured to fit the corresponding positioning groove 23. This helps to improve the installation stability of the integrated body 20 and reduces the gap between the countersunk groove 11 and the mounting hole 22, and between the positioning protrusion 12 and the positioning groove 23, thus reducing the problem of dirt accumulation.

[0088] In some embodiments, an arc surface can be formed between the opening of the positioning groove 23 and the mounting surface 21, and an arc surface can be formed between the bottom of the positioning groove 23 and the side wall. The positioning protrusion 12 is provided with an arc surface that matches the shape of the positioning groove 23, which makes it easier for the positioning protrusion 12 to be installed in the positioning groove 23 and avoids the positioning protrusion 12 from forming an inner corner that is difficult to clean, thus reducing the difficulty of cleaning.

[0089] In some embodiments, an arc surface is formed between the opening edge of the countersunk hole 221 and the mounting surface 21, and an arc surface is formed between the bottom of the countersunk hole 221 and the sidewall. The countersunk groove 11 is provided with an arc surface that matches the shape of the countersunk hole 221, which makes it easier for the countersunk groove 11 to enter the countersunk hole 221 and avoids the formation of difficult-to-clean inner corners in the countersunk groove 11, thus reducing the difficulty of cleaning.
