Description

Technical Field

[0001] This application relates to the field of clothing care technology, and in particular to a clothing treatment drum and drying device. Background Technology

[0002] Taking clothes dryers as an example, some devices have a functional layer attached to the inside of the drying drum. This functional layer provides functions such as moisturizing and sterilization. However, the assembly efficiency and installation effect of the functional layer in related technologies are not ideal. Utility Model Content

[0003] This application provides a clothes processing drum and a clothes drying device, which can improve assembly efficiency and installation effect.

[0004] In a first aspect, the garment processing tube proposed in the embodiments of this application includes:

[0005] tube body;

[0006] A functional layer component is disposed on the circumferential inner surface of the cylinder; and

[0007] At least two lifting ribs are connected to the cylinder body and press the functional layer assembly onto the circumferential inner surface of the cylinder body;

[0008] The functional layer component is provided with at least two first positioning parts, and each of the lifting ribs is provided with a second positioning part. The second positioning part of the lifting rib passes through the first positioning part and is connected to the cylinder body. The projected area of ​​at least one first positioning part on the inner surface of the circumference is greater than the projected area of ​​the other first positioning part on the inner surface of the circumference.

[0009] In one embodiment, the functional layer component includes a first end and a second end opposite to each other, at least one first positioning part is disposed between the first end and the second end of the functional layer component, and at least another first positioning part is disposed at the first end.

[0010] In one embodiment, the projection of the first positioning part on the circumferential inner surface of the cylinder body is located within the projection of the lifting rib on the circumferential inner surface of the cylinder body.

[0011] In one embodiment, the first positioning part includes a positioning hole, and the second positioning part includes a positioning protrusion, the positioning protrusion being disposed within the positioning hole.

[0012] In one embodiment, the positioning hole between the first end and the second end is an oblong hole, and the positioning hole extends axially along the cylinder body; and / or,

[0013] The positioning hole located at the first end is a circular hole.

[0014] In one embodiment, the first positioning part includes at least two positioning holes, the second positioning part includes at least two positioning protrusions, the at least two positioning holes are arranged at intervals along the extending direction of the lifting rib, and the at least two positioning protrusions are correspondingly inserted into the at least two positioning holes.

[0015] In one embodiment, the cylinder body is provided with at least two first connecting portions for each of the lifting ribs, the lifting ribs are provided with at least two second connecting portions, and the functional layer component is provided with at least two clearance holes for each of the lifting ribs. The first connecting portions and / or the second connecting portions pass through the clearance holes and are aligned and connected.

[0016] Along the extending direction of the lifting rib, at least two of the clearance holes and at least two of the positioning holes are alternately arranged at intervals.

[0017] In one embodiment, the functional layer component includes a first layered structure and a second layered structure. The first layered structure contacts the tubular body and serves as a support structure for generating a radially outward force on the tubular body, so that the functional layer component can abut against the circumferential inner surface of the tubular body. The second layered structure is located radially inside the first layered structure along the garment processing tubular body and serves as the external structure of the garment processing tubular body.

[0018] At least one of the first layered structure and the second layered structure serves as a functional structure.

[0019] In one embodiment, the functional layer component further includes an adhesive layer disposed between the first layered structure and the second layered structure, and bonding the first layered structure and the second layered structure together.

[0020] Secondly, embodiments of this application also propose a clothes drying device, comprising:

[0021] Air duct;

[0022] And a garment processing tube as described in any of the preceding claims, wherein the air duct is connected to a garment processing chamber within the garment processing tube for introducing airflow into the garment processing chamber.

[0023] Based on the above embodiments, in this application, after the functional layer components are placed into the cylinder and before the lifting rib is fixed to the cylinder body, the cooperation of the first positioning part and the second positioning part allows the assembly unit to quickly position the lifting rib to a suitable position and guide the alignment of the lifting rib and the part of the cylinder body used for connection, so as to fix the connection. This not only makes the process of assembling the lifting rib to the cylinder body more convenient and faster, improving assembly efficiency, but also improves the installation accuracy of the lifting rib to the cylinder body, reduces errors and misalignment, and improves product quality.

[0024] In this embodiment, when the lifting rib mates with the first positioning part with a larger projected area, the larger first positioning part allows for adjustment of the relative position between the lifting rib and the functional layer component, facilitating alignment and improving the compatibility of the functional layer component. After the lifting rib mates with the first positioning part with a larger projected area is fixed, the functional layer component, the cylinder body, and the lifting rib are aligned. Pairing another lifting rib with the first positioning part with a smaller projected area allows for precise alignment and connection between the lifting rib and the cylinder body. This ensures the compatibility of the functional layer component while maintaining the effective positioning between the first positioning part of the functional layer component and the second positioning part of the lifting rib, thus improving assembly efficiency.

[0035] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0037] Where the following description relates to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0038] In the description of this application, it should be understood that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances. Furthermore, in the description of this application, unless otherwise stated, "multiple" refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship.

[0039] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0040] This application provides a clothes drying device, which can be a dryer, washer-dryer combo, etc. The drying device includes an air duct and a clothes handling drum. The clothes handling drum has a clothes handling chamber for processing clothes. The air duct communicates with the clothes handling chamber inside the clothes handling drum to introduce airflow into the clothes handling chamber. In other words, this drying device can be used to dry clothes.

[0041] The location of the air duct outlet is not limited. For example, in some embodiments, the air duct outlet is located on the end cap, and the airflow from the air duct enters the garment processing chamber through the outlet on the end cap.

[0042] In some embodiments, the airflow within the garment processing chamber can be vented through a duct to the interior or exterior.

[0043] In other embodiments, both the inlet and outlet of the air duct are connected to the garment processing chamber to form a circulating air duct.

[0044] For example, the clothes dryer includes a front support disposed at the front end of the clothes handling drum for supporting the drum. An air duct inlet is disposed on the front support. That is, the airflow inside the clothes handling chamber enters the air duct through the inlet on the front support, undergoes condensation and dehumidification in the air duct, is then heated, and the heated airflow re-enters the clothes handling chamber from the outlet of the air duct, thus circulating in a cycle.

[0045] Please refer to the reference. Figures 1 to 2 The garment processing drum 100 includes a drum body 10, a functional layer component 20, and lifting ribs 30.

[0046] It should be noted that the cylinder body 10 has a clothing loading / unloading port 11 at one end along the axial direction. The clothing handling cylinder 100 also includes an end cap 14, which is located at the other end of the cylinder body 10 along the axial direction. That is, the clothing loading / unloading port 11 and the end cap 14 are located at opposite ends of the cylinder body 10 along the axial direction.

[0047] The cylinder body 10 and end cap 14 enclose a clothing processing cavity for holding clothing. The cylinder body 10 and end cap 14 constitute the main structure of the clothing processing cylinder 100. The cylinder body 10, as the main structural component of the clothing processing cylinder 100, must be made of a material that ensures the structural strength of the clothing processing cylinder 100. Exemplarily, in some embodiments, the cylinder body 10 is a metal cylinder body 10, that is, the material of the cylinder body 10 is metal, such as stainless steel.

[0048] In some embodiments, the tube body 10 is formed by winding a metal sheet, and the metal sheet is fastened at the joints of opposite ends along the winding direction, for example, by riveting or welding. Exemplarily, after the metal sheet is wound and fastened at the joints, one end of the tube body 10 is contracted inward to form a narrowed structure. The narrowed structure defines the garment insertion opening. Exemplarily, the tube body 10 is an airtight structure. That is, water, air, etc., cannot pass through the tube body 10; i.e., the tube body 10 does not have holes for water or air to pass through.

[0049] The functional layer assembly 20 covers the circumferential inner surface of the cylindrical body 10. The circumferential inner surface refers to the radially inner surface of the cylindrical body 10. That is, the shape of the functional layer assembly 20 is adapted to the shape of the cylindrical body 10, and is approximately cylindrical.

[0050] The phrase "covering the circumferential inner surface of the tube body 10" means that the functional layer component 20 covers the circumferential inner surface of the tube body 10, and the area of ​​the tube body 10 covered by the functional layer component 20 does not directly contact the clothing.

[0051] For example, the circumferential inner surface of the tube body 10 is a continuous smooth surface. That is, the tube body 10 has no patterns, i.e., no uneven structure. This facilitates close contact between the functional layer assembly 20 and the tube body 10, making the parts of the functional layer assembly 20 that come into contact with clothing relatively flat and less likely to abrade the clothing.

[0052] It is worth mentioning that in some embodiments, such as in a dryer, the clothes handling drum 100 does not need to come into contact with water. Therefore, the functional layer component 20 is basically not soaked in water. This reduces the requirements for the waterproof and corrosion-resistant properties of the material of the functional layer component 20, reduces the probability of damage to the noise reduction layer, and extends the service life of the functional layer component 20.

[0053] The lifting rib 30 is connected to the drum body 10. Specifically, the lifting rib 30 is located on the inner side of the drum body 10. There can be one or more lifting ribs 30. During the rotation of the garment processing drum 100, the lifting rib 30 carries the garments along with it. After the garments are lifted to a certain height, they fall back down under their own weight, thus loosening the garments.

[0054] For example, the lifting rib 30 presses the functional layer component 20 onto the circumferential inner surface of the cylinder body 10. In other words, while the lifting rib 30 is connected to the cylinder body 10, the functional layer component 20 is also connected to the cylinder body 10. In this way, the connection structure of the lifting rib 30 can be fully utilized, and there is no need to set an additional connection structure for the functional layer component 20 and the cylinder body 10, which facilitates assembly, improves assembly efficiency, and simplifies the connection structure between the functional layer component 20 and the cylinder body 10.

[0055] In addition, the lifting rib 30 has a relatively large area at one end facing the cylinder body 10. One end of the lifting rib 30 presses against the functional layer component 20, and the lifting rib 30 and the functional layer component 20 have a large contact area, which increases the force-bearing area of ​​the functional layer component 20, improves the connection reliability between the functional layer component 20 and the cylinder body 10, and makes the functional layer component 20 less prone to breakage.

[0056] In this embodiment of the application, the cylinder body 10 is provided with a first connecting part 15, and the lifting rib 30 is provided with a second connecting part 321. The first connecting part 15 and the second connecting part 321 are connected to fix the lifting rib 30 to the cylinder body 10. Specifically, the first connecting part 15 and the second connecting part 321 can be connected and fixed by means of buckle, bolt connection or other means. This embodiment of the application does not limit this.

[0057] In some embodiments, after the cylinder body 10 is formed, the functional layer component 20 is first placed inside the cylinder body 10, and then the lifting ribs 30 are connected to the cylinder body 10. To facilitate the connection between the lifting ribs 30 and the cylinder body 10, the functional layer component 20 is provided with at least two first positioning parts, and each lifting rib 30 is provided with a second positioning part. The second positioning part passes through the first positioning part and connects to the cylinder body 10. The first positioning part and the second positioning part can be positioned and engaged through a hole-shaft fit or a guide groove, etc., and are not limited here.

[0058] Understandably, after the functional layer component 20 is inserted into the cylinder body 10 and before the lifting rib 30 is fixed to the cylinder body 10, the cooperation of the first and second positioning parts allows the assembly unit to quickly position the lifting rib 30 in the appropriate position and guide the first connecting part 15 of the lifting rib 30 to align with the second connecting part 321 of the cylinder body 10. This not only makes the assembly of the lifting rib 30 to the cylinder body 10 more convenient and faster, improving assembly efficiency, but also improves the installation accuracy of the lifting rib 30 to the cylinder body 10, reduces errors and misalignments, and improves product quality.

[0059] Furthermore, the projected area of ​​at least one first positioning part on the circumferential inner surface is greater than the projected area of ​​the other first positioning part on the circumferential inner surface. Here, the projected area of ​​the first positioning part on the circumferential inner surface refers to the area of ​​the first positioning part projected onto the circumferential inner surface along the radial direction of the cylinder 10, which is the area possessed after the cylinder 10 is unfolded and flattened. Given the same circumferential inner surface, the size of the projected area reflects the size of the functional area of ​​the first positioning part. That is, the functional area of ​​at least one first positioning part is greater than the functional area of ​​the other first positioning part. Here, the functional area refers to the area where the first positioning part is used to cooperate with the second positioning part; for example, when the first positioning part is a positioning hole, the functional area refers to the space within the hole.

[0060] In this embodiment, when the lifting rib 30 mates with the first positioning part with a larger projected area, the larger first positioning part allows for adjustment of the relative position between the lifting rib 30 and the functional layer component 20, facilitating alignment and improving the compatibility of the functional layer component 20. After the lifting rib 30 mates with the first positioning part with a larger projected area is fixed, the functional layer component 20, the cylinder body 10, and the lifting rib 30 are aligned. Pairing another lifting rib 30 with the first positioning part with a smaller projected area allows for precise alignment and connection between the lifting rib 30 and the cylinder body 10. This ensures the compatibility of the functional layer component 20 while maintaining the effective positioning between the first positioning part of the functional layer component 20 and the second positioning part of the lifting rib 30, thus improving assembly efficiency.

[0061] Combination Figure 2 and Figure 7 In some embodiments, the first positioning part includes a positioning hole 24, and the second positioning part includes a positioning protrusion 331, which passes through the positioning hole 24. That is, in this embodiment, the first positioning part and the second positioning part are positioned by a shaft hole. During installation, the positioning protrusion 331 of the lifting rib 30 is inserted into the positioning hole 24 of the functional layer component 20 to achieve the initial positioning of the lifting rib 30 in the functional layer component 20. Since the functional layer component 20 is relatively fixed to the cylinder body 10, the lifting rib 30 can be positioned on the cylinder body 10 at the part for installing the lifting rib 30 through the cooperation of the positioning hole 24 and the positioning protrusion 331. The cooperation method of the positioning hole 24 and the positioning protrusion 331 is that the positioning protrusion 331 is inserted into the positioning hole 24 radially along the cylinder body 10. This is not only simple and effective, but also allows for a tighter fit between the lifting rib 30 and the functional layer component 20, achieving mutual constraint between the two and improving the connection stability between the lifting rib 30 and the functional layer component 20.

[0062] Of course, in other embodiments, the first positioning part may include a positioning protrusion 331, and the second positioning part may include a positioning hole 24, which is not limited here. In comparison, in actual production, it is simpler and more convenient to set the positioning hole 24 on the functional layer component 20 and the positioning protrusion 331 on the lifting rib 30, which is more efficient. Moreover, the positioning protrusion 331 on the lifting rib 30 has sufficient hardness and good positioning effect.

[0063] The following explanation will continue with the structural form of the first positioning part including the positioning hole 24 and the second positioning part including the positioning protrusion 331.

[0064] For example, the functional layer assembly 20 is constructed by winding a composite plate-like structure. When the functional layer assembly 20 is placed on the cylinder 10, the functional layer assembly 20 has a first end and a second end opposite each other in the circumferential direction, which is the circumferential direction of the cylinder 10 itself and is consistent with the winding direction. The first end and the second end are the two ends of the composite plate-like structure along the winding direction. The first end and the second end are spaced apart, making the thickness of each part of the functional layer assembly 20 more uniform, improving the compatibility of the functional layer assembly 20, and avoiding the impact on flatness caused by the overlap of the first end and the second end due to manufacturing tolerances.

[0065] In some embodiments, at least one first positioning portion is disposed between the first end and the second end of the functional layer assembly 20, and at least another first positioning portion is disposed at the first end. The area between the first end and the second end refers to the middle portion of the composite plate-like structure along the winding direction. Optionally, after the functional layer assembly 20 is placed in the cylinder 10, the first positioning portion located between the first end and the second end is radially opposite to the first positioning portion located at the first end of the cylinder 10, thereby facilitating targeted positioning of the lifting ribs 30.

[0066] Combination Figures 4 to 7 In one embodiment, the positioning hole located between the first end and the second end is an oval hole and extends axially along the cylinder body 10. In this embodiment, the positioning protrusion 331 occupies a portion of the positioning hole 24. Wherein, Figure 2 and Figure 4 In the structure shown, the winding direction is approximately circumferential to the cylinder 10. In this embodiment, when the positioning protrusion 331 passes through the positioning hole 24, the positioning protrusion 331 is allowed to slide within the positioning hole 24 along the extending direction of the positioning hole 24. This facilitates the adjustment of the position of the lifting rib 30 during installation, so that the first connecting portion 15 of the lifting rib 30 is aligned with the second connecting portion 321 of the cylinder 10, thus accommodating manufacturing errors of the cylinder 10 and the lifting rib 30 and improving the versatility and compatibility of the functional layer component 20.

[0067] Of course, in some other embodiments, the positioning protrusion 331 may be a polygonal protruding pillar structure, and the positioning hole 24 may be an elongated slot adapted to the positioning protrusion 331. This is not limited here.

[0068] In some embodiments, the positioning hole at the first end is a circular hole. The positioning protrusion 331 is correspondingly cylindrical. The outer diameter of the positioning protrusion 331 is smaller than the inner diameter of the positioning hole 24, so that the positioning protrusion 331 passes through the positioning hole 24 more smoothly, improving positioning efficiency. Of course, in other embodiments, provided that the shape of the positioning protrusion 331 matches the shape of the positioning hole at the first end, the positioning hole can also be of other shapes.

[0069] Furthermore, in a specific implementation, the positioning hole between the first end and the second end is an oval hole, and the positioning hole at the first end is a circular hole, which further facilitates the positioning operation of the lifting rib.

[0070] Optionally, the first positioning part includes at least two positioning holes 24, and the second positioning part includes at least two positioning protrusions 331. The at least two positioning holes 24 are arranged at intervals along the extending direction of the lifting rib 30, and the at least two positioning protrusions 331 are correspondingly inserted into the at least two positioning holes 24. Through the positioning cooperation of the at least two positioning protrusions 331 and the at least two positioning holes 24, the positioning of the lifting rib 30 relative to the cylinder body 10 can be more accurate, which is conducive to further improving the alignment accuracy. At the same time, the connection between the functional layer component 20 and the lifting rib 30 is tighter, which facilitates the preliminary limiting of the lifting rib 30 before it is fixed, which is conducive to improving assembly efficiency.

[0071] Provided that the shapes of the positioning hole 24 and the positioning protrusion 331 passing through the positioning hole 24 are compatible, the shapes of at least two positioning holes 24 of the same first positioning part may be the same or different, which is not limited here.

[0072] Combination Figure 2 In one embodiment, the projection of the first positioning portion on the circumferential inner surface of the cylinder body 10 lies within the projection of the lifting rib 30 on the circumferential inner surface of the cylinder body 10. That is, after the lifting rib 30 is installed onto the cylinder body 10, the first positioning portion is covered by the lifting rib 30 and is not exposed, improving the aesthetic appearance. Furthermore, the projections of the first connecting portion 15 and the second connecting portion 321 on the circumferential inner surface of the cylinder body 10 also lie within the projection of the lifting rib 30 on the circumferential inner surface of the cylinder body 10. This brings the first and second positioning portions closer to the first connecting portion 15 and the overlapping connecting portion, improving positioning accuracy.

[0073] In one embodiment, the cylinder body 10 has at least two first connecting portions 15 corresponding to each lifting rib 30, and the lifting rib 30 has at least two second connecting portions 321. The functional layer component 20 has at least two clearance holes 25 corresponding to each lifting rib 30. At least one of the first connecting portions 15 and the second connecting portions 321 passes through the clearance hole 25 and is aligned and connected. Exemplarily, the first connecting portion 15 protrudes towards the inner side of the cylinder body 10 and passes through the clearance hole 25. This facilitates the connection between the first connecting portion 15 and the second connecting portion 321 and also allows the outer side of the cylinder body 10 to be recessed. When using bolt connection, the bolt can be placed in the recessed area of ​​the first connecting portion 15 on the outer side of the cylinder body 10 to ensure the overall flatness of the outer side of the cylinder body 10 and avoid the protruding bolt interfering with the rotation of the cylinder body 10.

[0074] Along the extending direction of the lifting rib 30, at least two clearance holes 25 and at least two positioning holes 24 are alternately arranged. Thus, the multiple first connecting portions 15 and multiple second connecting portions 321 are arranged at intervals along the extending direction of the lifting rib 30, and multi-point fixing helps improve the connection reliability of the lifting rib 30. Simultaneously, the at least two positioning holes 24 and at least two positioning protrusions 331 are interspersed therein for positioning, which also improves positioning accuracy and stability of the lifting rib 30 during pre-positioning.

[0075] Combination Figure 7 In one embodiment, the lifting rib 30 includes a cover 31, a positioning post 33, a connecting post 32, a positioning reinforcement plate, and a connecting reinforcement plate 34. The cover 31 is a shell structure with an internal cavity, open towards the cylinder body 10. The side of the cover 31 with the opening presses against the functional layer assembly 20 to improve the fixing effect on the functional layer assembly 20. The positioning post 33 and the connecting post 32 are both connected to the cover 31 and extend towards the opening. One end of the positioning post 33 is exposed in the opening and has a positioning protrusion 331. One end of the connecting post 32 is exposed in the opening and has a second connecting part 321. The positioning reinforcement plate 35 and the connecting reinforcement plate 34 are respectively arranged around the positioning post 33 and the connecting post 32. The opposite sides of the positioning reinforcement plate 35 are respectively connected to the positioning post 33 and the cover 31, and the opposite sides of the connecting reinforcement plate 34 are respectively connected to the connecting post 32 and the cover 31. In this embodiment, the cooperation of the cover 31, positioning column 33, connecting column 32, positioning reinforcement plate and connecting reinforcement plate 34 achieves positioning and fixation, ensures structural strength, and leaves more space inside the lifting rib 30, resulting in low material cost.

[0076] Optionally, for each connecting post 32 and each positioning post 33, the number of connecting reinforcing plates 34 is greater than the number of positioning reinforcing plates 35. For example, each connecting post 32 is surrounded by four connecting reinforcing plates, while each positioning post 33 is surrounded by two positioning reinforcing plates. This targeted reinforcement of the connecting post 32 used for connecting to the cylinder body 10 ensures connection strength, while reducing structural support for the positioning post 33 that is not used for connection. This helps to further reduce material costs and also improves production efficiency during the production of the lifting ribs 30.

[0077] Furthermore, the cover 31, positioning post 33, connecting post 32, positioning reinforcement plate, and connecting reinforcement plate 34 are integrated into a single structure. For example, the lifting rib 30 can be injection molded as a single unit, resulting in good structural integrity and high production efficiency.

[0078] In this embodiment, the functional layer component 20 refers to a component that has at least one of the functions of moisturizing, sterilizing, and noise reduction. By setting the functional layer component 20 inside the drum body 10, the clothes drying drum can have functions such as moisturizing, sterilizing, and noise reduction, thereby improving the functionality of the drying equipment and enhancing the user experience. The following example illustrates the use of the functional layer component 20 for noise reduction.

[0079] Understandably, during the operation of a clothes dryer, zippers, buttons, and other fasteners on clothing will randomly strike the drum, producing sharp knocking sounds and causing significant noise pollution. To address this issue, in conjunction with... Figure 4 and Figure 8 In some embodiments, the functional layer component 20 includes a first layered structure 23 and a second layered structure 21, with the second layered structure 21 located radially inside the first layered structure 23 along the garment processing tube 100. It should be noted that the first layered structure 23 and the second layered structure 21 are separated by layers along the thickness direction of the functional layer component 20. The first layered structure 23 is generally cylindrical around the circumference of the tube body 10, and the second layered structure 21 is also generally cylindrical around the circumference of the tube body 10. The first layered structure 23 and the second layered structure 21 are stacked.

[0080] The first layer structure 23 is in contact with the tube body 10. That is, the first layer structure 23 is the outermost layer of the functional layer component 20 in the radial direction. The second layer structure 21 serves as the external structure of the clothing handling tube 100. The second layer structure 21 is exposed in the clothing handling cavity, and the user can see the second layer structure 21 through the clothing loading and unloading port 11.

[0081] At least one of the first layered structure 23 and the second layered structure 21 serves as a functional structure; in this embodiment, the functional structure is a vibration damping and noise reduction structure. The vibration damping and noise reduction structure contains sound-insulating and noise-reducing materials to absorb vibration noise to a certain extent.

[0082] For example, the first layered structure 23 includes at least one of foamed plastic, foamed rubber, and foamed silicone. Foamed plastic is lightweight, sound-absorbing, vibration-damping, and corrosion-resistant, which helps to reduce the overall weight of the garment processing drum; foamed rubber and foamed silicone have good viscoelasticity and good damping effect in vibration reduction. The second layered structure 21 includes at least one of leather and a metal layer. The leather can be genuine leather or artificial leather. Leather can be easily processed into the required colors, patterns, etc., to achieve rich process designs. In addition, leather is relatively soft and can absorb loads and impacts and vibrations from foreign objects to a greater extent.

[0083] In the clothing processing drum 100 of this application embodiment, since the functional layer component 20 covers the circumferential inner surface of the drum body 10, the clothing does not directly contact the inner surface of the drum body 10, but rather contacts the functional layer component 20. When foreign objects such as buttons and zippers of the clothing strike the clothing processing drum 100, the functional layer component 20 can convert and absorb at least part of the vibration, thereby reducing the vibration amplitude transmitted to the drum body 10. This can suppress the generation of vibration noise to a certain extent and reduce the noise radiated outward by the clothing processing drum 100, thereby achieving a high noise reduction. In addition, the functional layer component 20 has a large coverage area on the drum body 10, which can play a large-scale noise reduction role.

[0084] The clothing processing tube 100 of this application embodiment has a layered design for the functional layer component 20. While meeting the requirements of noise reduction, it can also improve the industrial design flexibility of the second layer structure 21 and enhance the appearance of the functional layer component 20. In addition, users or operators can directly and visually observe the position, wear and tear of the functional layer component 20, which is convenient for timely maintenance and / or replacement.

[0085] For example, at least one of the first layered structure 23 and the second layered structure 21 serves as a support structure to generate a radially outward force on the cylinder 10, so that the functional layer assembly 20 can abut against the circumferential inner surface of the cylinder 10 under the action of the force. It should be noted that the support structure not only needs to have a certain structural strength, but also needs to have a certain toughness to apply a radially outward force to the cylinder 10.

[0086] The radial outward force exerted on the cylinder 10 refers to the fact that the supporting structure, under the action of its own material, exerts a certain radial outward force on the cylinder 10. This force is conducive to attaching the functional layer component 20 as a whole to the circumferential inner surface of the cylinder 10, and the functional layer component 20 as a whole is not easy to collapse or lift off the cylinder 10 under its own gravity.

[0087] In this embodiment, the force of the supporting structure helps to maintain the functional layer component 20 on the cylinder body 10 and helps to maintain the structural shape of the functional layer component 20. Even if the functional layer component 20 is only partially connected to the cylinder body 10, the entire functional layer component 20 can reliably rest on the circumferential inner surface of the cylinder body 10 and is not easy to collapse or lift off the cylinder body 10.

[0088] For example, the functional layer component 20 includes an adhesive layer 22 disposed between the first layered structure 23 and the second layered structure 21, and bonding the first layered structure 23 and the second layered structure 21 together. The adhesive layer 22 acts as a carrier to achieve a gapless connection between the first layered structure 23 and the second layered structure 21, making it less likely for the first layered structure 23 and the second layered structure 21 to delaminate.

[0089] Specifically, the adhesive layer 22 is a structure formed after the glue has cured. Specifically, during the manufacturing process, glue can be applied to one side of the first layered structure 23, or to one side of the second layered structure 21, or glue can be applied to one side of the first layered structure 23 and one layer of the second layered structure 21; the first layered structure 23 and the second layered structure 21 are then bonded together, and after the glue has cured, the first layered structure 23 and the second layered structure 21 are fixed together without gaps, and the adhesive layer 22 is formed after the glue has cured.

[0090] The specific type of adhesive is not limited, and the appropriate adhesive can be selected according to the different materials of the first layer structure 23 and the second layer structure 21.
