The two drums are interconnected to form a single unit and share a vibration damper mounted on the large drum. However, when the large drum experiences large eccentric vibrations, such as during spin drying and dehydration, the small drum will follow the eccentric vibrations of the large drum and strike the corresponding door glass, posing a risk of damage to the door glass or the small drum.

[0015] The circular ring is attached to the inner wall of the inner cylinder near the inner cylinder opening, the retaining ring extends radially outward from the outer edge of the circular ring, and a round chamfer is formed between the retaining ring and the circular ring.
[0016] Optionally, the end of the protrusion facing the inner cylinder is located between the end surface of the retaining ring facing away from the inner cylinder and the sealing fold.
[0017] Optionally, the protrusion includes a large diameter section and a small diameter section connected to each other, the large diameter section is located on a side of the small diameter section away from the inner cylinder, and the sealing fold abuts against a step surface between the large diameter section and the small diameter section.

[0024] The technical solution provided by the embodiments of the present disclosure may include the following beneficial effects: the clothing processing device provided by the present disclosure is configured such that the end of the protrusion of the door body facing the inner cylinder is located between the inner cylinder opening and the sealing fold, that is, the end of the protrusion facing the inner cylinder is located outside the accommodating space of the inner cylinder. At this time, there is no overlapping portion between the projections of the protrusion and the inner cylinder in the radial direction, so that even when eccentric vibration occurs in the inner cylinder, the protrusion will not collide with the protrusion. Taking the first cylinder as the one with the relatively smaller diameter of the two cylinders as an example, the eccentric vibration of the first cylinder following the second cylinder with the larger diameter is particularly severe, and since the inner cylinder diameter of the small cylinder is smaller, it is closer to the protrusion. Therefore, the risk of collision between the inner cylinder and the protrusion can be effectively avoided by ensuring that the end face of the protrusion of the door body close to the opening does not exceed the end face of the inner cylinder provided with the opening.
[0025] It is to be understood that the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the disclosure. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0031] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
[0032] like Figure 1 As shown, an exemplary embodiment of the present disclosure provides a clothes processing device, which may be a double-drum washing machine, a double-drum drying machine, a double-drum washer-dryer, etc.
[0033] Reference Figure 1 and Figure 2The present disclosure exemplarily shows a clothing processing device, comprising a housing 1 having an opening 23, a first barrel 2 and a second barrel 3 arranged in the housing 1, a vibration damper connected between at least one of the first barrel 2 and the second barrel 3 and the housing 1, a door body and a door seal 6 arranged at the opening 23. The first barrel 2 and the second barrel 3 are connected to each other, and the connection can be achieved specifically by a connector and a fastener, or the two can be directly welded, etc. The present disclosure does not limit the connection method between the first barrel 2 and the second barrel 3. The first barrel 2 includes an outer barrel 21 and an inner barrel 22, the inner barrel 22 has an inner barrel opening, and the outer barrel has an outer barrel opening. The inner barrel 22 and the outer barrel 21 are sleeved on each other, the outer barrel 22 of the first barrel 2 is connected to the second barrel 3 (follows vibration), and the inner barrel 22 is installed on the inner side of the outer barrel 21 and can move with the outer barrel 21. The door body is positioned at the opening 23 to enable opening and closing of the door 23. The door body has a protrusion 4 extending toward the opening 23. Specifically, the protrusion 4 may be made of sight glass, sight plastic, or the like. A door seal 6 is positioned at the outer tube opening and includes a sealing pleat 61. The protrusion 4 seals against the sealing pleat 61, specifically, the portion of the protrusion 4 facing away from the inner tube 22. In the axial direction of the inner tube 22, the end of the protrusion 4 facing the inner tube 22 is located between the inner tube opening and the sealing pleat 61. Specifically, the end of the protrusion 4 facing the inner tube 22 is located on the side of the inner tube opening facing away from the main body of the inner tube 22, and thus, is located outside the inner tube 22's accommodating space. This prevents radial collision with the protrusion 4 during radial eccentric movement of the inner tube 22.
[0034] It should be explained that, in the embodiment of the present disclosure, the door seal 6 can be constructed as a ring that matches the shape of the outer cylinder mouth, and the door seal 6 is usually made of rubber material. By setting the door seal 6, when the door body is closed, the protrusion 4 presses against the door seal 6 to play a sealing role, and the door seal 6 can avoid the protrusion 4 from rigidly colliding with other components. Since the structure, material and function of the door seal 6 are well known to those skilled in the art, they will not be introduced in detail here. Furthermore, the sealing folds 61 refer to the fold structure formed on the door seal 6, which has the following functions: Enhanced sealing: The folds increase the flexibility and elasticity of the door seal, so that it can better fit the door frame, thereby improving the sealing effect; Extended service life: By dispersing stress, the folds can reduce the wear and tear of the door seal when opening and closing the door, thereby extending its service life; Improved thermal insulation performance: The folds can form multiple air layers to improve thermal insulation performance; and Adaptive deformation: The folds allow the door seal 6 to deform under different temperature and humidity conditions, ensuring that a good sealing effect can be maintained in various environments.
[0035] Because in the present disclosure, the vibration damper usually includes a suspension spring and a damper, wherein the suspension spring is hung between the cylinder and the housing 1, and the damper is supported between the cylinder and the housing 1. In the present disclosure, a vibration damper is provided between at least one of the first cylinder 2 and the second cylinder 3 and the housing 1, which means that the first cylinder 2 and the second cylinder 3 share a set of vibration dampers. Specifically, the suspension spring and the damper can be both provided on the first cylinder 2 or both provided on the second cylinder 3, or the suspension spring and the damper are separately provided on the first cylinder 2 and the second cylinder 3. The first cylinder 2 and the second cylinder 3 share a set of vibration dampers, which is conducive to reducing the adverse effects such as vibration superposition caused by the configuration of independent vibration dampers for each cylinder, thereby improving the vibration damping effect. Moreover, the first cylinder 2 and the second cylinder 3 share a set of vibration dampers, which is also conducive to reducing the number of vibration dampers used, simplifying the structure in the clothing processing equipment, and reducing the design and manufacturing costs.
[0036] It should be explained that the end of the protrusion 4 facing the inner cylinder 22 refers to the end of the protrusion 4 closest to the inner cylinder 22, that is, this end does not exceed the inner cylinder opening (located outside the inner cylinder 22), so it can be ensured that the protrusion 4 as a whole does not exceed the inner cylinder opening (all located outside the inner cylinder 22) and is located between the inner cylinder opening and the sealing fold 61.
[0037] By using the above-mentioned technical solution, the laundry processing device provided by the present disclosure is configured such that the end of the protrusion 4 of the door body facing the inner drum 22 is located between the inner drum opening and the sealing fold 61, that is, the end of the protrusion 4 facing the inner drum 22 is located outside the accommodating space of the inner drum 22. At this time, the projections of the protrusion 4 and the inner drum 22 in the radial direction do not overlap, so that even when the inner drum 22 vibrates eccentrically, the protrusion 4 will not collide with the protrusion 4. Taking the first drum 2 as the one with the smaller diameter of the two drums as an example, the eccentric vibration of the first drum 2 following the second drum 3 with the larger diameter is particularly severe, and since the inner drum 22 of the smaller drum has a smaller diameter and is closer to the protrusion 4, the risk of collision between the inner drum 22 and the protrusion 4 can be effectively avoided by ensuring that the end face of the protrusion 4 of the door body close to the opening 23 does not exceed the end face of the inner drum 22 provided with the opening 23.
[0038] In the disclosed embodiment, the linear distance D1 between the end of the protrusion 4 facing the inner drum 22 and the inner drum opening can satisfy D1 ≤ 10 mm. Specifically, this linear distance can be 1 mm, 5 mm, or 10 mm. The upper limit of this linear distance is set to prevent the protrusion 4 from being too far from the inner drum opening, preventing it from being able to stop the clothing inside the inner drum 22 and causing the clothing to fall out of the inner drum 22 and into the gap between the protrusion 4 and the inner drum 22. In other embodiments, this linear distance D1 can also satisfy D1 ≤ 8 mm, etc., and can be designed adaptively based on actual conditions.
[0039] Furthermore, in the embodiment of the present disclosure, in the axial direction of the inner tube 22, the end of the protrusion 4 facing the inner tube 22 can be located between the inner tube opening and the outer tube opening. Alternatively, the end of the protrusion 4 facing the inner tube 22 can also be located between the outer tube opening and the sealing fold 61. The specific selection can be adaptively made according to actual needs.
[0040] Reference Figure 1 and Figure 2 In an embodiment of the present disclosure, an inner cylinder ring 5 may be further provided at the inner cylinder opening, and the inner cylinder ring 5 may include a circular ring 51 and a retaining ring 52. The circular ring 51 may be attached to the inner wall of the inner cylinder 22 near the inner cylinder opening, and the retaining ring 52 may extend radially outward from the outer edge of the circular ring 51, with a rounded chamfer formed between the retaining ring 52 and the circular ring 51. Since the inner cylinder 22 is made of sheet metal, the end with the opening 23 is usually sharp. Providing an inner cylinder ring 5 with a rounded chamfer at this position can prevent the "sharp" end of the inner cylinder 22 from leaking out and damaging clothing or causing injury to the user. In addition, the inner cylinder ring 5 can also provide an installation location for other related components. The present disclosure does not limit the specific structure of the inner cylinder ring 5, which can be adaptively designed according to actual needs. The structure and principle of the inner cylinder ring 5 are well known to those skilled in the art.
[0041] It should be noted that the "outer edge of the ring 51" here refers to the edge of the inner cylinder 22. During installation, the inner cylinder ring 51 is simply extended from the outside of the inner cylinder 22 to the inside of the inner cylinder 22 (the ring 51 is extended), and the retaining ring 52 is located outside the end surface corresponding to the inner cylinder opening of the inner cylinder 22 and is pressed against the inner cylinder 22.
[0042] Furthermore, in the embodiment of the present disclosure, the end of the protrusion 4 facing the inner cylinder 22 can be located between the end surface of the retaining ring 52 facing away from the inner cylinder 22 and the sealing fold 61, that is, the end of the protrusion 4 facing the inner cylinder 22 is located outside the inner cylinder ring 5. This design can prevent the inner cylinder ring 5 from rotating with the inner cylinder 22 and colliding with the protrusion 4 when the inner cylinder 22 vibrates eccentrically.
[0043] Reference Figure 2 In the embodiment of the present disclosure, the protrusion 4 may include a large diameter section 41 and a small diameter section 42 connected to each other. The large diameter section 41 is located on the side of the small diameter section 42 away from the inner cylinder 22, and the sealing fold 61 may abut against the step surface between the large diameter section 41 and the small diameter section 42. It should be noted that the large diameter section 41 and the small diameter section 42 may be constructed in an equal diameter shape, or may be constructed in a Figure 2 The expansion shape shown in the figure gradually increases in diameter in the direction away from the inner tube opening. This expansion design is beneficial to prevent clothes from entering and being stuck between the door seal 6 and the small diameter section 42.
[0044] Reference Figure 2In an embodiment of the present disclosure, the laundry processing apparatus may further include retaining ribs 7 disposed on the outer periphery of the protrusion 4. Here, the retaining ribs 7 are located on the outer periphery of the protrusion 4, rather than being formed with the protrusion 4. The retaining ribs 7 extend radially from the outside to the inside toward the small-diameter section 42. The retaining ribs 7 can prevent the laundry in the inner drum 22 from moving into the gap between the door seal 6 and the small-diameter section 42.
[0045] In the disclosed embodiment, the retaining rib 7 can be configured as a ring surrounding the protrusion 4. This allows the retaining rib 7 to be present at various circumferential locations, thereby enhancing the aforementioned blocking (stopping) effect. Furthermore, in other embodiments, the retaining rib 7 can also be configured as a strip and provided in multiple configurations, with the multiple retaining ribs 7 being evenly distributed along the circumference of the small-diameter section 42.
[0046] This disclosure does not impose any restrictions on the radial distance between the retaining rib 7 and the minor diameter section 42. For example, in the embodiments of this disclosure, the radial distance D2 between the retaining rib 7 and the protrusion 4 can satisfy 5mm≤D2≤10mm, specifically 5mm, 7.5mm, or 10mm. The upper limit of the radial distance D2 is set to ensure its stopping effect; the lower limit is set to prevent the retaining rib 7 from being too close to the minor diameter section 42, resulting in interference between the retaining rib 7 and the minor diameter section 42 when the door is opened or closed.
[0047] This disclosure does not limit the formation method of the retaining rib 7. For example, in the embodiments of this disclosure, the retaining rib 7 and the door seal 6 can be integrally formed. This design can reduce the number of parts, assembly difficulty, and production costs. Furthermore, in other embodiments, the retaining rib 7 and the door seal 6 can also be assembled to form a single unit.
[0048] In the embodiment of the present disclosure, the diameter of the first barrel 2 can be smaller than that of the second barrel 3. That is, the first barrel 2 serves as the small barrel of the laundry processing device and its diameter can be 120mm-200mm. In this case, the radial distance between its inner barrel 22 and the protrusion 4 is relatively small. The second barrel 3 serves as the large barrel and has greater vibration energy. Therefore, when the second barrel 3 vibrates eccentrically, it can drive the first barrel 2 to produce more violent eccentric motion, which can easily cause the inner barrel 22 to collide with the protrusion 4. Therefore, the technical solution of the present disclosure is particularly effective when applied to a first barrel 2 with a smaller diameter.
[0049] Those skilled in the art will readily appreciate other embodiments of the present disclosure after considering the specification and practicing the solutions disclosed herein. This application is intended to cover any variations, uses, or adaptations of the present disclosure that follow the general principles of the present disclosure and include common knowledge or customary techniques in the art not disclosed herein. The description and examples are to be considered as exemplary only, with the true scope and spirit of the present disclosure being indicated by the appended claims.
[0050] It should be understood that the present disclosure is not limited to the exact structures that have been described above and shown in the drawings, and that various modifications and changes can be made without departing from the scope thereof. The scope of the present disclosure is limited only by the appended claims.
