[0060] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0061] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also include the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not construed as requiring them to be performed in a particular order described or illustrated unless the order of performance is explicitly indicated. It should also be understood that additional or alternative steps may be used.

[0062] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

[0063] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "over," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure is flipped, an element described as "below other elements or features" or "below other elements or features" would subsequently be oriented as "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0064] Clothing processing equipment with drying function can dry clothes, thus meeting users' needs for clothing processing.

[0065] For example, a clothes drying device is a clothes dryer. When drying clothes, the clothes are placed in the clothes drying drum of the clothes dryer. The hot air generated by the drying components flows into the clothes drying drum and rotates. During the rotation, the lifting components lift and flip the clothes, so that the clothes are in full contact with the hot air. The hot air continuously removes the moisture from the clothes, thereby achieving the purpose of drying the clothes.

[0066] In related technologies, the inner wall of the garment processing chamber is made of metal. During the garment processing process, hard objects on the garment (such as zippers and buttons) will randomly hit the inner wall of the garment processing chamber, resulting in sharp knocking sounds and causing significant noise pollution, which affects the user experience.

[0067] like Figures 1 to 11As shown, according to an embodiment of the present invention, a garment processing tube 30 is proposed, which includes a tube body 31 and an inner lining assembly 32.

[0068] The cylinder 31 has an approximately cylindrical structure and a rotation axis, allowing it to rotate around the rotation axis. When the garment processing cylinder 30 is used in the garment processing device 100, the drive assembly of the garment processing device 100 is connected to the garment processing cylinder 30. The drive assembly drives the garment processing cylinder 30, causing it to rotate around its own rotation axis. This allows the garments placed in the garment processing chamber 314 to be turned over, reducing garment stacking and improving the garment processing effect.

[0069] The material of the cylinder 31 can be metal or non-metal.

[0070] For example, when the cylinder 31 is made of metal, taking stainless steel as an example, it is formed by cutting and stamping stainless steel plates and then assembling them. The assembly points can be connected and fixed by riveting or welding. Making the cylinder 31 of stainless steel can improve the overall structural strength of the cylinder 31, thereby reducing the deformation of the cylinder 31 and thus reducing the likelihood of malfunctions in the clothing processing cylinder 30.

[0071] For example, when the cylinder 31 is made of non-metallic material, taking plastic as an example, the cylinder 31 can be processed by injection molding or other methods, thereby reducing the number of processing steps for the cylinder 31, improving production efficiency, and reducing manufacturing costs.

[0072] The cylinder 31 includes a clothing processing cavity 314 and an inner peripheral wall. The inner peripheral wall is arranged around the rotation axis of the cylinder 31 and is part of the inner surface of the cylinder 31. The clothing processing cavity 314 is formed inside the cylinder 31, and the inner peripheral wall encloses part of the clothing processing cavity 314. The clothing processing cavity 314 has an approximately cylindrical structure. The axis of the clothing processing cavity 314 is consistent with the rotation axis of the cylinder 31. This arrangement can reduce the offset of the center of gravity of the clothing processing cylinder 30, and reduce the situation where the clothing processing cylinder 30 will sway due to the offset of the center of gravity during rotation, which will affect the clothing processing effect.

[0073] The inner lining assembly 32 is disposed in the garment processing cavity 314 of the cylinder 31, and the inner lining assembly 32 is fitted against the inner peripheral wall of the cylinder 31. The inner lining assembly 32 is disposed on one side of the inner peripheral wall, and the inner lining assembly 32 separates the inner peripheral wall from the garment processing cavity 314. The inner lining assembly 32 has at least the ability to block the noise generated in the garment processing cavity 314, that is, the noise generated in the garment processing cavity 314 cannot be transmitted to the outside of the garment processing cylinder 30 through the inner lining assembly 32.

[0074] The inner lining assembly 32 includes layered portions, the number of which is two or more (when the number of layered portions is more than three, it means three or more, for example, the specific number of layered portions can be three, four, five, six, seven, eight, etc.), and the multiple layered portions are stacked along the radial direction of the cylinder 31. Among the multiple layered portions are a first layered portion 325 and a second layered portion 326. The first layered portion 325 is disposed facing the garment processing cavity 314 and is configured to contact the garment during the garment processing process. The second layered portion 326 is disposed on the side of the first layered portion 325 away from the garment processing cavity 314 and contacts the inner peripheral wall of the cylinder 31. The first layered portion 325 and the second layered portion 326 may or may not be connected.

[0075] For example, the first layered portion 325 and the second layered portion 326 are not connected. In this case, the first layered portion 325 and the second layered portion 326 can be stacked in the radial direction of the cylinder 31, and the two are only physically attached to each other.

[0076] For example, the first layered portion 325 and the second layered portion 326 are connected, and the first layered portion 325 and the second layered portion 326 can be directly connected or indirectly connected. When the first layered portion 325 and the second layered portion 326 are directly connected (the connection method can be snap-fit, spraying, or vulcanization, etc.), the gap between the first layered portion 325 and the second layered portion 326 can be reduced, so as to reduce the overall thickness of the lining assembly 32, thereby minimizing the impact of the lining assembly 32 on the space inside the garment processing cavity 314.

[0077] When the first layer 325 and the second layer 326 are indirectly connected (the two can be connected by an auxiliary layer), the distance between the first layer 325 and the second layer 326 can be increased. When a hard object on the clothing hits the first layer 325, the noise blocking effect can be improved, thereby improving the noise isolation performance of the inner lining assembly 32 in the clothing processing cavity 314.

[0078] The hardness of the first layered portion 325 is less than the hardness of the inner peripheral wall of the cylinder 31, and the hardness of the second layered portion 326 is also less than the hardness of the inner peripheral wall of the cylinder 31. Furthermore, the hardness of the first layered portion 325 is less than the hardness of the second layered portion 326. In this application, hardness specifically refers to the ability of a material to locally resist the indentation of a hard object onto its surface.

[0079] When the garment processing drum 30 is used in the garment processing equipment 100 and the garments are being processed, the garments are placed in the garment processing chamber 314. During the processing, the first layered portion 325 faces the garment processing chamber 314 and contacts the garments. When the drum body 31 of the garment processing drum 30 rotates around its own axis, the garments are tumbled in the garment processing chamber 314. Hard objects on the garments (such as zippers and buttons) collide with the first layered portion 325. The hardness of the first layered portion 325, the second layered portion 326, and the inner peripheral wall of the drum body 31 increases sequentially. The noise generated by the hard objects on the garments colliding with the first layered portion 325 is less than the noise generated by the hard objects on the garments directly colliding with the inner peripheral wall of the drum body 31. Furthermore, the second layered portion 326 acts as a barrier between the first layered portion 325 and the inner peripheral wall of the drum body 31, thereby reducing the noise inside the garment processing drum 30 and achieving noise isolation. This reduces the transmission of noise to the outside, thereby improving the user experience.

[0080] It should be understood that, in this application, the functions that the inner lining component 32 can have include, but are not limited to, blocking noise in the clothing processing chamber 314, sterilizing, inhibiting and disinfecting the clothing processing chamber 314, and keeping the clothing processing chamber 314 warm.

[0081] For example, when the inner lining assembly 32 has sterilization, bacteriostasis and disinfection functions for the garment processing cavity 314, substances such as silver ions or polymeric bactericidal substances can be provided in the layered part of the inner lining assembly 32.

[0082] For example, when the inner lining assembly 32 has a heat preservation function for the clothing processing chamber 314 (when the clothing processing equipment 100 used in the clothing processing drum 30 is a dryer), the inner lining assembly 32 is made of heat preservation material. At this time, the inner lining assembly 32 can form a heat preservation layered structure in the clothing processing chamber 314, so that the clothing processing chamber 314 can be insulated from the outside, thereby reducing the heat exchange between the clothing processing chamber 314 and the outside and affecting the effect of clothing processing.

[0083] The inner circumferential wall of the cylinder 31 can be a continuous smooth surface, or it can have a patterned surface or a raised structure.

[0084] For example, when the inner circumferential wall of the tube body 31 is a smooth surface, it is easy for the inner lining assembly 32 to fit against the inner circumferential wall, so as to improve the tightness between the inner lining assembly 32 and the inner circumferential wall, thereby improving the flatness of the inner lining assembly 32, reducing the wrinkles of the inner lining assembly 32, and thus reducing the wear and tear on the clothes.

[0085] For example, when the inner peripheral wall of the cylinder 31 has a surface with a raised structure, the shape of the surface of the inner lining component 32 that is in contact with the inner peripheral wall is adapted to the shape of the inner peripheral wall (a structure adapted to the shape of the inner peripheral wall is provided on the inner lining component 32, or the surface of the inner lining component 32 that is in contact with the inner peripheral wall can undergo elastic deformation to adapt to the shape of the inner peripheral wall). This can increase the area of ​​the inner peripheral wall and increase the contact area between the inner peripheral wall and the raised structure. When there is a connection between the inner lining component 32 and the inner peripheral wall, the strength of the connection can be improved, thereby improving the structural strength and stability of the inner lining component 32.

[0086] In some embodiments of this utility model, such as Figure 10 As shown, the inner lining assembly 32 includes multiple layered portions, which are stacked along the radial direction of the cylinder 31. These multiple layered portions include a first layered portion 325, a second layered portion 326, and a third layered portion 327.

[0087] The first layered portion 325 is disposed facing the clothing processing cavity 314 of the cylinder 31 and is used to contact clothing. The second layered portion 326 is disposed on the side of the first layered portion 325 away from the clothing processing cavity 314. The third layered portion 327 is disposed between the first layered portion 325 and the second layered portion 326, wherein the third layered portion 327 is connected to the first layered portion 325 and the second layered portion 326 respectively.

[0088] The first layer 325 and the second layer 326 are connected by the third layer 327. This maintains the relative position between the first layer 325 and the second layer 326, reduces the possibility of loosening due to vibration between the first layer 325 and the second layer 326, and increases the structural stability of the inner liner assembly 32 to improve the noise blocking effect.

[0089] It should be understood that by setting the third layer 327, the number of layers of the inner lining assembly 32 can be increased. With the increase in the number of layers, when a hard object on the clothing hits the first layer 325, the transmission path of the impact sound can be increased, thereby further improving the noise blocking effect.

[0090] It should be noted that the third layered portion 327 can be a rigid layered structure. For example, the third layered portion 327 can be a foam layer or other layered structure. The connection method between the third layered portion 327 and the first layered portion 325 includes, but is not limited to, bonding, snap-fitting, or connection by fasteners.

[0091] In some embodiments of this utility model, the third layer 327 is an adhesive layer.

[0092] Specifically, a third layered portion 327 is disposed between the first layered portion 325 and the second layered portion 326, and the first layered portion 325 and the second layered portion 326 are connected through the third layered portion 327. The third layered portion 327 is configured as an adhesive layer, which acts as a carrier, achieving a gapless connection between the first layered portion 325 and the second layered portion 326, making it less prone to delamination.

[0093] It is important to understand that the adhesive layer is specifically the structure formed after the glue has cured. During the manufacturing process, glue can be applied to one side of the first layered portion 325, or to one side of the second layered portion 326, or glue can be applied to one side of the first layered portion 325 and one layer of the second layered portion 326. The first layered portion 325 and the second layered portion 326 are then bonded together. After the glue has cured, the first layered portion 325 and the second layered portion 326 are fixed together without gaps, and the adhesive layer is formed after the glue has cured.

[0094] In this application, the specific type of adhesive is not limited, and a suitable adhesive can be selected according to the different materials of the first layer 325 and the second layer 326.

[0095] It should be noted that the thickness of the inner lining component 32 (the dimension of the inner lining component 32 along the radial direction of the cylinder 31) is 1.0mm to 3.0mm, that is, 1.0mm≤D≤3.0mm.

[0096] For example, thicknesses of 1mm, 1.1mm, 1.2mm, 1.3mm, 1.5mm, 1.7mm, 1.9mm, 2.0mm, 2.1mm, 2.2mm, 2.3mm, 2.4mm, 2.5mm, 2.6mm, 2.8mm, 2.9mm, and 3.0mm are used. By controlling the thickness of the inner lining component 32, it is possible to ensure that the inner lining component 32 has corresponding structural strength and noise reduction effect, while reducing the space occupied within the garment processing cavity 314.

[0097] It should be noted that, unless otherwise specified, the thickness in the embodiments of this application refers to the dimension placed radially along the garment processing tube 30.

[0098] In some embodiments of this utility model, the thickness of the first layered portion 325 is in the range of 0.1 mm to 0.4 mm.

[0099] Specifically, the thickness of the first layered portion 325 (the dimension of the first layered portion 325 along the radial direction of the cylinder 31) is 0.1 to 0.4 mm, for example, 0.1 mm, 0.14 mm, 0.18 mm, 0.2 mm, 0.23 mm, 0.25 mm, 0.28 mm, 0.3 mm, 0.32 mm, 0.34 mm, 0.35 mm, 0.36 mm, 0.37 mm, 0.38 mm, 0.4 mm, etc.

[0100] In some embodiments of this utility model, the thickness of the second layer 326 is in the range of 0.9 mm to 2.6 mm.

[0101] Specifically, the thickness of the second layer 326 (the dimension of the second layer 326 along the radial direction of the cylinder 31) is 0.9mm to 2.6mm, i.e., 0.9mm≤d2≤2.6mm. For example, 0.9mm, 1.0mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.65mm, 1.7mm, 1.76mm, 1.8mm, 1.9mm, 2mm, 2.2mm, 2.3mm, 2.5mm, 2.6mm, etc.

[0102] In some embodiments of this utility model, the thickness of the third layer 327 is in the range of 0.05 mm to 0.3 mm.

[0103] Specifically, the thickness of the third layer 327 (the dimension of the third layer 327 along the radial direction of the cylinder 31) is 0.05mm to 0.3mm, that is, 0.05mm≤d4≤0.3mm. For example, 0.05mm, 0.06mm, 0.08mm, 0.09mm, 0.1mm, 0.14mm, 0.15mm, 0.16mm, 0.17mm, 0.18mm, and 0.2mm.

[0104] In some embodiments of this utility model, the first layered portion 325 and the second layered portion 326 are both flexible layers.

[0105] Specifically, since the first layered portion 325 faces the garment processing cavity 314 and is used to contact the garment, the first layered portion 325 is configured as a flexible layer. When a hard object on the garment impacts the first layered portion 325, the first layered portion 325 undergoes elastic deformation, thereby absorbing the impact force of the hard object and reducing the noise generated by the impact, thereby improving the noise barrier effect of the inner lining assembly 32 in the garment processing cavity 314.

[0106] Furthermore, the second layered portion 326 can directly or indirectly contact the inner peripheral wall of the cylinder 31. For example, if the second layered portion 326 directly contacts the inner peripheral wall of the cylinder 31, then the second layered portion 326 is fitted to the inner peripheral wall of the cylinder 31. The second layered portion 326 is a flexible layer. Because the second layered portion 326 directly contacts the inner peripheral wall of the cylinder 31, and is made of a flexible material, it avoids rigid contact between the second layered portion 326 and the inner peripheral wall of the cylinder 31, and also has the function of vibration reduction and noise reduction. The second layered portion 326 can also be understood as a vibration damping layer.

[0107] In some embodiments of this invention, the hardness of the first layered portion 325 is in the range of 60HA to 63HA.

[0108] Specifically, the hardness of the first layer 325 is set in the range of 60HA to 63HA, which enables the first layer 325 to have good flexibility. When a hard object of clothing hits the first layer 325, the first layer 325 can absorb the impact force of the hard object, thereby reducing the noise generated by the impact of the hard object.

[0109] It should be understood that setting the hardness of the first layer 325 in the range of 60HA to 63HA gives the first layer 325 good wear resistance, reduces scratches caused by hard objects to the first layer 325, and thus extends the service life of the inner liner assembly 32.

[0110] It should be noted that the specific hardness values ​​of the first layer 325 can be 60.5HA, 61HA, 61.5HA, 62HA, 62.5HA, 63HA, etc.

[0111] In some embodiments of this invention, the hardness of the second layer 326 is in the range of 64HA to 68HA.

[0112] Specifically, during the garment processing, the first layer 325 comes into direct contact with the garment. Hard objects on the garment impact the first layer 325, and the resulting noise is transmitted through the first layer 325 to the second layer 326. By setting the hardness of the second layer 326 within the range of 64HA to 68HA, the second layer 326 becomes flexible. This flexibility allows the noise transmitted to the second layer 326 to be attenuated, thereby reducing the amount of noise transmitted outward through the second layer 326 and improving the noise isolation effect of the inner lining assembly 32.

[0113] It should be understood that by setting the hardness of the second layer 326 in the range of 64HA to 68HA, the second layer 326 has a certain structural strength, thereby generating tension. This tension can improve the fit between the inner lining assembly 32 and the inner peripheral wall of the cylinder 31, and reduce the possibility of the inner lining assembly 32 collapsing.

[0114] It should be noted that the specific values ​​of the hardness of the first layer 325 can be 64HA, 64.5HA, 65HA, 65.5HA, 66HA, 66.5HA, 67HA, 67.5HA, 68HA, etc.

[0115] In some embodiments of this utility model, the tensile strength of the first layered portion 325 is in the range of 4.7 MPa to 5.2 MPa.

[0116] Specifically, during the garment processing, the first layer 325 comes into direct contact with the garment, and friction is generated between the garment and the first layer 325. By setting the tensile strength of the first layer 325 within the range of 4.7 MPa to 5.2 MPa, the first layer 325 can have better tensile performance, reducing the deformation of the first layer 325 caused by friction during use and resulting in wrinkles, thus improving the garment processing effect and extending the service life of the inner lining component 32.

[0117] It should be noted that the specific hardness values ​​of the first layer 325 can be 4.7 MPa, 4.8 MPa, 4.9 MPa, 5 MPa, 5.1 MPa, or 5.2 MPa.

[0118] In some embodiments of this invention, the tensile strength of the second layered portion 326 is in the range of 5.2 MPa to 5.7 MPa.

[0119] Specifically, during the garment processing, the inner lining assembly 32 rotates synchronously with the tubular body 31, and the second layered portion 326 is fixed relative to the tubular body 31 (the second layered portion 326 can be directly or indirectly connected to the tubular body 31). By setting the tensile strength of the second layered portion 326 in the range of 5.2 MPa to 5.7 MPa, the situation of rotational inertia elongating the second layered portion 326 is reduced, thereby improving the adhesion effect between the inner lining assembly 32 and the inner peripheral wall of the tubular body 31 and reducing the possibility of the inner lining assembly 32 separating from the tubular body 31.

[0120] It should be noted that the specific hardness values ​​of the first layer 325 can be 5.2 MPa, 5.3 MPa, 5.4 MPa, 5.5 MPa, 5.6 MPa, or 5.7 MPa.

[0121] In this application, at least one of the first layered portion 325 and the second layered portion 326 can generate a supporting force for the inner liner assembly 32. The supporting force is a force in the radially outward direction toward the cylinder 31, thereby forming a supporting structure for the inner liner assembly 32 so that the inner liner assembly 32 can fit against the inner peripheral wall of the cylinder 31.

[0122] In some embodiments of this utility model, the second layered portion 326 has tension along the radial direction of the cylinder 31, and the tension drives the inner lining assembly 32 to abut against the inner peripheral wall.

[0123] Specifically, the second layer 326 has tension in the direction of radially outward of the cylinder 31. The second layer 326 serves as a support structure for the inner liner assembly 32 and is used to generate radially outward tension on the cylinder 31 so that the inner liner assembly 32 can abut against the inner peripheral wall of the cylinder 31 under the action of tension.

[0124] It should be noted that the supporting structure not only needs a certain structural strength, but also a certain toughness, so as to apply radial outward tension to the cylinder 31.

[0125] The radial outward tension on the cylinder 31 refers to the fact that the supporting structure, under the action of its own material, exerts a certain radial outward force on the cylinder 31. This force is beneficial to attach the inner lining component 32 to the inner circumferential wall of the cylinder 31 as a whole, and the inner lining component 32 is not easy to collapse or lift off the cylinder 31 under its own weight.

[0126] In this embodiment, the tension of the support structure helps to maintain the inner lining component 32 on the cylinder 31 and helps to maintain the structural shape of the inner lining component 32. Even if the inner lining component 32 is only partially connected to the cylinder 31, the entire inner lining component 32 can reliably rest against the inner peripheral wall of the cylinder 31 and is not easy to collapse or lift off the cylinder 31.

[0127] In some embodiments of the present invention, the first layered portion 325 includes at least one of a leather layer and a fabric layer.

[0128] Specifically, the first layered portion 325 can be a leather layer structure formed solely of leather, a fabric layer structure formed solely of fabric, or a composite layer structure formed of leather and fabric.

[0129] For example, the first layer 325 is a leather layer structure formed solely by leather, which can be genuine leather or artificial leather. Leather can be easily processed to produce the desired colors (brown, orange, etc.), patterns (embossed or sprayed patterns, etc.), etc., enabling a wide range of design possibilities. In addition, leather is relatively soft and can absorb loads and impacts and vibrations from foreign objects to a greater extent. At the same time, leather can also present a high-end visual feel and provide soft care for clothing.

[0130] In some embodiments of the present invention, the second layered portion 326 includes at least one of a foam layer, a rubber layer, and a silicone layer.

[0131] Specifically, the second layer 326 may be a foam layer formed only of foaming material, a rubber layer formed only of rubber material, a silicone layer formed only of silicone material, or a composite layer structure formed by at least two of foaming material, rubber material and silicone material.

[0132] For example, the second layer 326 is a foamed layer (the edges of the foamed layer are sealed to reduce water ingress and thus reduce bacterial growth due to water ingress). The foamed layer can be made of foamed plastic, which is lightweight, sound-absorbing, vibration-damping, and corrosion-resistant, thus reducing the overall weight of the garment treatment drum 30. Foamed plastic, also known as microporous plastic, refers to a type of polymer material formed by a large number of gas micropores dispersed in a solid plastic, with the entire structure covered by countless interconnected or non-interconnected micropores. Foamed plastic can be made of polyurethane (PUR), polystyrene (PS), polyvinyl chloride (PVC), polyethylene (PE), phenolic resin (PF), etc.

[0133] The foam layer can also be foamed rubber or foamed silicone, which has good viscoelasticity and good damping effect in vibration reduction.

[0134] In some embodiments of this utility model, the first layered portion 325 is leather, the first layered portion 325 is foam plastic, the foam plastic serves as a supporting structure and also has a certain vibration damping effect, the leather has a large degree of absorption of load and impact and vibration from foreign objects, and at the same time, the leather can show a high-end visual feel and provide soft care for clothing.

[0135] In some embodiments of this invention, the hardness of the first layer 325 can be greater than that of the second layer 326. For example, the first layer 325 is a metal layer (e.g., a stainless steel layer or an aluminum foil layer, on which patterns can be processed to at least improve the visual appeal), and the second layer 326 is a material with good viscoelasticity, such as foamed rubber or foamed silicone. The viscoelastic foam layer, acting as a vibration-damping and dissipating layer, can absorb a large amount of load and impact vibration energy transmitted from the metal layer. The metal layer, as a structural support, can generate significant tension on the cylinder 31 and also achieve a wear-resistant and antibacterial functional surface, making it less susceptible to scratches from sharp parts of clothing and extending the service life of the inner lining assembly 32. In this embodiment, the first layer 325 of the metal layer and the cylinder 31 form a sandwich structure, with the second layer 326 sandwiched between them. Because the second layer 326 has good damping properties, it can achieve a good noise reduction effect.

[0136] In some embodiments of this utility model, such as Figures 3 to 6 ,as well as Figure 8 As shown, the cylindrical body 31 includes a cylindrical body 311 and two end caps. The two end caps are respectively disposed at opposite ends of the cylindrical body 311 along the axial direction of the cylindrical body 311. The two end caps and the cylindrical body 311 enclose a garment processing cavity 314. An inner peripheral wall is formed on the inner surface of the cylindrical body 311. A slot 315 is formed between the end caps and the inner peripheral wall. The ends of the inner lining assembly 32 at opposite ends along the axial direction of the cylindrical body 31 are disposed in the corresponding slots 315.

[0137] Specifically, the tube body 311, as the main structural component of the garment processing tube 30, requires a material that ensures the structural strength of the garment processing tube 30. The thickness of the tube body 311 is 0.3mm to 0.7mm, that is, 0.3mm ≤ thickness of the tube body 311 ≤ 0.7mm. For example, 0.3mm, 0.4mm, 0.45mm, 0.5mm, 0.6mm, 0.67mm, 0.7mm, etc. This thickness range ensures that the tube body 31 has good structural strength and is also easy to process.

[0138] It should be noted that, unless otherwise specified, the thickness in the embodiments of this application refers to the dimension placed radially along the garment processing tube 30.

[0139] The cylinder body 311 is made of rolled metal sheets, and the metal sheets are fastened at the joints of opposite ends along the winding direction, for example, by riveting or welding.

[0140] The cylinder body 311 is an airtight structure. That is to say, water, air and other substances cannot pass through the cylinder body 311, meaning that the cylinder body 311 does not have any holes for water or air to pass through.

[0141] The garment processing drum 30 includes two end caps, which are located at opposite ends of the drum body 311 along the axial direction of the drum body 31. One end cap is a first end cap 313, and the other end cap is a second end cap 312.

[0142] The first end cap 313 is disposed at the front end of the cylinder body 311 along the axial direction. The first end cap 313 is generally annular, surrounds the front end of the cylinder body 311, and defines the clothing inlet. The inner diameter of the clothing inlet is smaller than the inner diameter of the cylinder body 311. The second end cap 312 is disposed at the rear end of the cylinder body 311 along the axial direction and covers the open portion of the rear end of the cylinder body 311.

[0143] A slot 315 is formed between the end cap and the circumferential inner surface of the cylinder 311, and the ends of the inner liner assembly 32 at opposite ends along the axial direction of the cylinder 311 are disposed in the corresponding slots 315. The slot formed between the first end cap 313 and the circumferential inner surface of the cylinder 311 is the first slot 3151, and the slot formed between the second end cap 312 and the circumferential inner surface of the cylinder 311 is the second slot 3152. The front end of the inner liner assembly 32 is inserted into the first slot 3151, and the rear end is inserted into the second slot 3152.

[0144] It should be noted that the slot can be a continuous annular slot or multiple sub-slots spaced out along the circumference. The front end of each inner liner component 32 is inserted into a different sub-slot, and the rear end of each inner liner component 32 is inserted into a different sub-slot.

[0145] The slot formed by the end cap and the barrel body limits the axial end of the inner lining assembly 32, preventing it from warping or deforming. Furthermore, the slot facilitates pre-positioning of the inner lining assembly 32 during assembly, eliminating the need for operators to manually hold the assembly, thus improving ease of assembly.

[0146] The first end cap 313 is riveted to the front end of the cylinder body 311. Specifically, a portion of the material of the first end cap 313 and a portion of the front end of the cylinder body 311 are rolled and riveted outwards.

[0147] The second end cap 312 is riveted to the rear end of the cylinder body 311. Specifically, a portion of the material of the second end cap 312 and a portion of the rear end of the cylinder body 311 are rolled and riveted outwards.

[0148] It should be noted that during the riveting process between the first end cap 313 and the cylinder body 311, the dimension of the first slot 3151 along the radial direction of the cylinder body 31 can remain unchanged or undergo a small deformation, which is not restricted here. During the riveting process between the second end cap 312 and the cylinder body 311, the dimension of the second slot 3152 along the radial direction of the cylinder body 31 can remain unchanged or undergo a small deformation, which is not restricted here.

[0149] The length of the slot along the axial direction of the cylinder 31 is not less than 2 mm, for example, it can be 2 mm to 6 mm. The length of the slot affects the axial overlap length between the end of the inner liner assembly 32 along the axial direction of the cylinder 31 and the end cap. The slot needs to have a suitable length so that the end cap can reliably limit the end of the inner liner assembly 32 along the axial direction of the cylinder 31.

[0150] It should be noted that the dimension of the slot along the radial direction of the cylinder 31 can be slightly larger than, equal to, or slightly smaller than the thickness of the inner liner assembly 32. That is, the end cap can generate a clamping force on the inner liner assembly 32 to press the inner liner assembly 32 against the inner circumferential wall of the cylinder 31, or the end cap can only provide radial restraint for the inner liner assembly 32 without providing radial preload.

[0151] In some embodiments of this utility model, such as Figure 3 , Figure 4 , Figure 6 And to Figure 8 As shown, the garment processing cylinder 30 also includes a lifting component 33, which is disposed in the garment processing cavity 314 and connected to the inner peripheral wall. The lifting component and the inner peripheral wall cooperate to clamp the inner lining component 32.

[0152] The inner lining assembly 32 includes a first end 328 and a second end 329 that are opposite each other in the circumferential direction of the tube body 31. The first end 328 is provided with a first edge line 3281 and a first clearance hole 322 that extends through the thickness direction of the layered portion. The edge line of at least one first clearance hole 322 coincides with at least a portion of the first edge line 3281. The lifting assembly 33 is disposed in the garment processing cavity 314 and connected to the tube body 311 of the tube body 31 through at least one first clearance hole 322.

[0153] The inner lining assembly 32 may include one plate-shaped member, two plate-shaped members, or multiple plate-shaped members (three or more) along the circumferential direction of the cylinder 31. The plate-shaped members surround the cylindrical structure, which is coaxially arranged with the cylinder 31.

[0154] The inner circumferential walls of the lifting assembly 33 and the cylinder 31 clamp the inner liner assembly 32 to facilitate its fixation. Specifically, the first end 328 and the second end 329 of the inner liner assembly 32 along the circumferential direction of the cylinder 31 are respectively clamped below the lifting assembly 33, thereby reducing the exposure of the splicing position of the inner liner assembly 32 and improving the flatness of the inner liner assembly 32 after assembly.

[0155] In addition, the lifting component 33 is disposed in the garment processing cavity 314 and connected to the body 311 of the tube 31 through at least one first clearance hole 322. In this way, the lifting component 33 and the inner lining component 32 have a mating structure, so that the lifting component 33 can be used to further limit the inner lining component 32, thereby improving the positional accuracy of the inner lining component 32 and reducing the possibility of the inner lining component 32 loosening and falling off.

[0156] Specifically, the number of boosting components 33 can be one or more.

[0157] During the rotation of the garment processing drum 30, the lifting component 33 carries the garments along with it. After the garments are lifted to a certain height, they fall back down under their own weight, which loosens the garments.

[0158] The lifting component and the inner peripheral wall cooperate to clamp the inner liner assembly 32. In other words, while the lifting component 33 is connected to the cylinder body 311, the inner liner assembly 32 is also connected to the cylinder body 311. In this way, the connection structure of the lifting component 33 can be fully utilized, and there is no need to set an additional connection structure for the inner liner assembly 32 and the cylinder body 311. This facilitates assembly, improves assembly efficiency, and simplifies the connection structure between the inner liner assembly 32 and the cylinder body 311.

[0159] In addition, the end of the lifting component 33 facing the cylinder body 311 has a relatively large area. One end of the lifting component 33 presses against the inner liner component 32, and the lifting component 33 and the inner liner component 32 have a large contact area, which increases the force-bearing area of ​​the inner liner component 32, improves the connection reliability between the inner liner component 32 and the cylinder body 311, and makes the inner liner component 32 less prone to breakage.

[0160] It should be understood that the liner assembly 32 can be a cylindrical member or a cylindrical structure formed by at least one plate member.

[0161] When the inner liner assembly 32 passes through the cylindrical structure formed by at least one plate-like member, the end faces of the opposite ends along the winding direction are aligned and do not overlap. In this way, the thickness of the inner liner assembly 32 is relatively uniform.

[0162] In some embodiments of this application, such as Figure 4As shown, the inner lining assembly 32 includes at least one plate-shaped member, which is detachably wrapped around the inner peripheral wall of the tubular body 311. The plate-shaped member has a multi-layered structure. Along the radial direction of the tubular body 311, the plate-shaped member has a first layered portion 325 and a second layered portion 326. The first layered portion 325 is used to contact clothing, and the second layered portion 326 abuts against the tubular body 311 and generates radially outward tension on the tubular body 311. At least one of the first layered portion 325 and the second layered portion 326 is a functional structure, and the elastic modulus of the first layered portion 325 is less than the elastic modulus of the second layered portion 326. Meanwhile, the lifting assembly 33 is connected to the tubular body 311 and located inside the tubular body 311. The lifting assembly 33 cooperates with the tubular body 311 to clamp the inner lining assembly 32.

[0163] Specifically, by designing the inner lining assembly 32 in layers, and making at least one of the first layer 325 and the second layer 326 a functional structure, the functionality of the inner lining assembly 32 is enhanced, enabling it to meet different usage needs. This improves the applicability of the garment processing tube 30 and enhances the customer's user experience. Furthermore, it increases the design flexibility of the first layer 325, improving the aesthetics of the inner lining assembly 32 and the garment processing tube 30. Moreover, users or operators can visually observe the position and wear of the inner lining assembly 32, facilitating subsequent maintenance or replacement.

[0164] Furthermore, by designing the inner liner assembly 32 in layers and making the elastic modulus of the first layer 325 smaller than that of the second layer 326, the inner liner assembly 32 can have a certain strength, thereby forming a better shape structure and helping to improve the adhesion of the inner liner assembly 32 to the inner peripheral wall. On the other hand, by setting the first layer 325 and the second layer 326 to have different elastic moduli, the inner liner assembly 32 has a better deformation effect when the lifting assembly 33 is installed and the lifting assembly 33 squeezes the inner liner assembly 32, which helps to reduce the damage to the inner liner assembly 32 caused by squeezing. It can also ensure the contact effect between the inner liner assembly 32 and the lifting assembly 33, and improve the stability and reliability of the installation of the inner liner assembly 32.

[0165] Furthermore, the inner liner assembly 32 includes at least one plate-like member, which is detachably wrapped around the inner peripheral wall of the drum body 311. In this case, the area of ​​the drum body 311 covered by the inner liner assembly 32 does not directly contact the clothes. When the clothes handling drum 30 of this application is used in a dryer, the clothes will come into contact with the inner liner assembly 32. Since the drum body 311 has a cylindrical structure, the shape of the plate-like member wrapped around the drum body 311 is adapted to the shape of the drum body 311, and it is generally cylindrical.

[0166] In this embodiment, there is one plate-shaped component, which covers the inner peripheral wall of the cylinder 311. The plate-shaped component has a multi-layer structure, optionally a three-layer structure. Along the radial direction of the cylinder 311, the plate-shaped component has a first layered portion 325, a third layered portion 327, and a second layered portion 326 arranged sequentially. The first layered portion 325 and the second layered portion 326 are connected by the third layered portion 327, that is, the third layered portion 327 is a connecting layer. Optionally, the connecting layer is specifically a structure formed after the adhesive has cured. The specific type of adhesive is not limited, and a suitable adhesive can be selected according to the different materials of the first layered portion 325 and the second layered portion 326. This application will not impose further restrictions here.

[0167] Specifically, the first layered portion 325 is used to contact clothing. In this case, the first layered portion 325 can serve as the external structure of the clothing processing tube 30, that is, the first layered portion 325 is exposed in the clothing processing cavity 314. The user can see the first layered portion 325 through the clothing loading and unloading port, which helps to improve the industrial design flexibility of the first layered portion 325, enhance the appearance of the inner lining component 32, and also allows direct observation of the wear or staining of the inner lining component 32, facilitating timely maintenance. At the same time, the second layered portion 326 abuts against the tube body 311 and generates radial outward tension on the tube body 311. This tension helps to maintain the inner lining component 32 on the tube body 311 and maintain the structural shape of the inner lining component 32. Even if the inner lining component 32 is only partially connected to the tube body 311, the entire inner lining component 32 can effectively abut against the inner peripheral wall of the tube body 311, thereby preventing the inner lining component 32 from collapsing or lifting off the tube body 311 under its own weight.

[0168] Optionally, at least one of the first layered portion 325 and the second layered portion 326 is a functional structure, which includes, but is not limited to, noise reduction, heat preservation, sterilization, and bacteriostasis. The following description uses noise reduction as an example; other requirements such as heat preservation, sterilization, and bacteriostasis will not be detailed here. Specifically, when clothing comes into contact with the inner lining component 32, and when hard objects (buttons, zippers, etc.) on the clothing strike the clothing processing drum 30, noise is easily generated. In this case, at least one of the first layered portion 325 and the second layered portion 326 can be set as a noise reduction structure. The inner lining component 32 can convert and absorb at least part of the vibration, thereby reducing the vibration amplitude transmitted to the drum body 311, suppressing the generation of vibration noise to a certain extent, and reducing the noise radiated outward from the clothing processing drum 30, thereby achieving the effect of noise reduction. Moreover, if the inner lining component 32 covers a large area on the drum body 311, noise reduction can be achieved to the maximum extent.

[0169] Furthermore, the elastic modulus of the first layered portion 325 is smaller than that of the second layered portion 326. By making the elastic modulus of the first layered portion 325 smaller than that of the second layered portion 326, on the one hand, due to the difference in the elastic modulus of the materials, the transmission efficiency of sound waves in the first layered portion 325 and the second layered portion 326 is different, and attenuation will occur during the process from the first layered portion 325 to the second layered portion 326, thereby achieving the effect of noise reduction; on the other hand, due to the difference in the elastic modulus of the materials, the flexural modulus of the first layered portion 325 and the second layered portion 326 is different. By making the elastic modulus of the first layered portion 325 smaller than that of the second layered portion 326, the inner liner assembly 32 can have a certain structural strength and toughness, which helps to further ensure the adhesion effect of the inner liner assembly 32 on the cylinder body 311.

[0170] A lifting assembly 33 is provided inside the cylinder body 311, and the lifting assembly 33 is connected to the cylinder body 311. It is understood that the lifting assembly 33 can be a lifting rib structure or a column structure; this application does not impose any restrictions on this. During the rotation of the garment processing cylinder 30, the lifting assembly 33 can rotate with the garments, and after the garments are lifted to a certain height, they will detach from the lifting assembly 33 due to their own gravity, thereby loosening the garments. Optionally, the lifting assembly 33 cooperates with the cylinder body 311 to clamp the inner lining assembly 32. The inner lining assembly 32 utilizes its own structural characteristics to cover the inner circumferential wall of the cylinder body 311, and the lifting assembly 33 fixes the inner lining assembly 32 to the cylinder body 311, effectively ensuring the installation effect of the inner lining assembly 32.

[0171] The inner liner assembly 32 includes a plate-like member wound to form a cylindrical structure. Along the circumference of the cylindrical body 311, the plate-like member has a first end 328 and a second end 329. In this embodiment, a gap region 321 exists between the first end 328 and the second end 329. The lifting assembly 33 includes two lifting members arranged opposite to each other. Specifically, one of the two lifting members simultaneously presses against the first end 328 and the second end 329 and covers the gap region 321, while the other directly presses against the plate-like member. That is, in the projection of the inner circumferential wall of the cylindrical body 311, the gap region 321 is located within the area covered by the first lifting member on the inner circumferential wall of the cylindrical body 311. In other words, the arc length of the plate-like member is less than the circumference of the inner circumferential wall of the cylindrical body 311. The arrangement of the gap region 321 helps to reduce the manufacturing precision requirements of the inner liner assembly 32. Furthermore, it facilitates the avoidance of the connection portion 3421 between the first lifting member and the cylindrical body 311.

[0172] In other embodiments of this application, a single plate-shaped member is provided, and the plate-shaped member is wound to form a cylindrical structure. Along the circumference of the cylindrical body 311, the two ends of the plate-shaped member do not overlap, and the end faces of the two ends are aligned. This helps to ensure that the thickness of each part of the inner lining assembly 32 is relatively uniform. At the same time, by having the lifting assembly 33 directly press against the cylindrical body 311, it helps to prevent the two ends of the plate-shaped member from warping.

[0173] Furthermore, such as Figure 8 As shown, the inner lining assembly 32 also includes a fastening assembly 34, which is disposed on the cylinder body 311 and is used to fix the inner lining assembly 32 to the cylinder body 311. By setting the fastening assembly 34, the position of the inner lining assembly 32 can be positioned and installed. At the same time, in conjunction with the structural characteristics of the inner lining assembly 32, the lifting assembly 33, and the inner peripheral wall of the cylinder body 311, the fixing effect of the inner lining assembly 32 on the cylinder body 311 can be effectively guaranteed, and the collapse or warping of the inner lining assembly 32 can be further prevented.

[0174] It is understood that the fastening component 34 can directly act on the inner liner component 32 and fix the inner liner component 32 to the cylinder body 311, or cooperate with other components such as the lifting component 33 and the end cap to fix the inner liner component 32. In this embodiment, the fastening component 34 includes a first fastener 341, which passes through the cylinder body 311 and is connected to the lifting component 33, so that the lifting component 33 cooperates with the cylinder body 311 to clamp the inner liner component 32. Optionally, the first fastener 341 is set as a screw or stud. The lifting component 33 is provided with a mounting post 332, and the cylinder body 311 is provided with a mounting hole (not shown). The first fastener 341 passes through the mounting hole and is screwed onto the mounting post 332. On the one hand, it can realize the positioning and installation of the inner liner component 32; on the other hand, it can also drive the lifting component 33 to move towards the cylinder body 311, thereby cooperating with the cylinder body 311 to clamp the inner liner component 32.

[0175] The plate-shaped component is provided with a plurality of first clearance holes 322. When the first fastener 341 passes through the cylinder body 311 and is screwed onto the mounting post 332, the first fastener 341 passes through the first clearance holes 322. At this time, the first clearance holes 322 are provided to correspond to the mounting holes and provide a marking function for the installation of the inner lining component 32. On the other hand, the first clearance holes 322 can avoid the mounting post 332 or the first fastener 341 and cooperate with the mounting post 332 or the first fastener 341 to form a limit on the inner lining component 32.

[0176] In this embodiment, as Figure 4 and Figure 8As shown, the first clearance hole 322 is provided on the plate-shaped member. The lifting assembly 33 includes two lifting members. Correspondingly, the first clearance hole 322 includes two sets. The two sets of first clearance holes 322 are arranged at intervals along the circumference of the cylinder body 311. Optionally, the number of first clearance holes 322 in each set is three, and the three first clearance holes 322 are arranged at intervals along the axial direction of the cylinder body 311. This arrangement helps to ensure the stability of the lifting member installation.

[0177] In some embodiments of this utility model, such as Figure 11 As shown, the first end 328 and the second end 329 of the cylinder 31 are opposite each other in the circumferential direction. The first end 328 is provided with a first edge line 3281. A first clearance hole 322 is provided on the first end 328, which extends through the thickness direction of the layered portion. At least one edge line of the first clearance hole 322 coincides with at least a portion of the first edge line 3281.

[0178] The second end 329 is provided with a second edge line 3291, which is adapted to be joined with at least a portion of the first edge line 3281. The first edge line 3281 and the second edge line 3291 are spaced apart along the circumference of the cylinder 31. The minimum distance between the first edge line 3281 and the second edge line 3291 is D1, and the maximum distance between the first edge line 3281 and the second edge line 3291 is D2, wherein D1 < 0.5 * D2.

[0179] Specifically, when the inner lining assembly 32 includes one plate-shaped member along the circumferential direction of the cylinder 31, the plate-shaped member is wound to form a cylindrical structure. At this time, along the circumferential direction of the cylinder 311, the inner lining assembly 32 includes a first end 328 and a second end 329 that are arranged opposite to each other. The first end 328 and the second end 329 can abut against each other or be spaced apart. When the first end 328 and the second end 329 are spaced apart, the space between them is the spaced area.

[0180] At least one first clearance hole 322 coincides with at least a portion of the first edge line 3281, that is, the first clearance hole 322 is configured to penetrate the first end 328. The minimum distance between the first edge line 3281 and the second edge line 3291 is D1, and the maximum distance between the first edge line 3281 and the second edge line 3291 is D2, wherein D1 < 0.5 * D2. This configuration ensures that the first end 328 and the second end 329 are subjected to uniform force, reducing the possibility of wrinkling of the inner lining assembly 32 due to uneven force on the first end 328 and the second end 329 during use, as well as the possibility of the first end 328 and / or the second end 329 detaching from the inner wall of the cylinder 31.

[0181] It should be understood that the first clearance hole 322 can be a complete through hole or an incomplete through hole. When the first clearance hole 322 is a complete through hole, the center is the midpoint of the lifting component 33. Therefore, D1 is less than half of D2 to ensure that the lifting component 33 will not be excessively biased towards the first end 328 after installation. If it is too biased towards the first end 328, it will reduce the clamping area of ​​the second end 329, increasing the risk that the inner liner component 32 will slip out due to insufficient clamping area.

[0182] When the inner lining assembly 32 includes multiple plate-shaped members along the circumferential direction of the cylinder 31, the two adjacent plate-shaped members are the first end 328 and the second end 329 mentioned above, which will not be described in detail here.

[0183] The outer peripheral wall of the cylinder body 311 has multiple receiving grooves 3111 formed by recesses. The inner peripheral wall of the cylinder body 311 has protruding structures corresponding to the receiving grooves 3111. Each protruding structure corresponds to a first clearance hole 322, meaning the number of receiving grooves 3111 (protruding structures) is the same as the number of first clearance holes 322. The protruding structures are embedded in the first clearance holes 322. In this case, the protruding structures can limit the movement of the inner liner assembly 32 when it covers the inner peripheral wall of the cylinder body 311, which helps improve assembly efficiency. Simultaneously, one end of the first fastener 341 is housed in the receiving groove 3111, and the other end of the first fastener 341 passes through the receiving groove 3111 and connects to the lifting assembly 33. This arrangement helps ensure the smoothness of the outer peripheral wall of the cylinder body 311, facilitating the subsequent installation of waterproof components and reducing the occurrence of water leakage.

[0184] Furthermore, such as Figure 4 and Figure 8 As shown, the inner liner assembly 32 is provided with a plurality of positioning holes 323, and the fastening assembly 34 includes a second fastener 342. The first end 328 of the second fastener 342 is provided with a pressing part 3422. The second fastener 342 includes a connecting part 3421 and a pressing part 3422. The insertion end of the connecting part 3421 passes through the cylinder body 311 and the positioning holes 323 in sequence. A limiting member is provided at the insertion end. The limiting member cooperates with the pressing part 3422 to make the inner liner assembly 32 abut against the cylinder body 311.

[0185] Specifically, by setting a second fastener 342 on the cylinder body 311, the inner liner assembly 32 can be initially fixed, which facilitates the subsequent fixed installation of the lifting assembly 33 and can effectively prevent the inner liner assembly 32 from shifting or shaking during the installation of the lifting assembly 33.

[0186] It should be understood that the cylinder body 311 is formed by rolling a metal plate, and a rolled edge structure 3112 is formed at the joint. In this embodiment, there are multiple positioning holes 323, and the multiple positioning holes 323 are spaced apart along the axial direction of the cylinder body 311. Optionally, some of the multiple positioning holes 323 are respectively arranged at both ends of the rolled edge structure 3112 along the circumference of the cylinder body 311, and when the lifting assembly 33 is fixed on the cylinder body 311, the lifting assembly 33 can cover the second fastener 342, which helps to reduce the occurrence of water leakage. At the same time, another part of the multiple positioning holes 323 is located on the same straight line as the first clearance hole 322, so as to reduce the processing area of ​​the inner lining assembly 32, thereby ensuring that the lifting assembly 33 can cover the second fastener 342.

[0187] In this embodiment, as Figure 7 As shown, the second fastener 342 includes a connecting portion 3421 and a pressing portion 3422. The insertion end of the connecting portion 3421 passes through the cylinder body 311 and the positioning hole 323 in sequence. A limiting member is provided at the insertion end. The pressing portion 3422 can be formed on the connecting portion 3421, or the pressing portion 3422 and the connecting portion 3421 can be detachably connected. This application does not impose any restrictions on this. Optionally, the second fastener 342 is a rivet. The pressing portion 3422 shown can be formed at the insertion end of the second fastener 342 through a stretching operation. At this time, the pressing portion 3422 abuts against the plate-like portion. Moreover, a limiting structure is formed at the end of the connecting portion 3421 away from the pressing portion 3422. The limiting structure abuts against the outer peripheral wall of the cylinder body 311. At this time, the connecting portion 3421 and the pressing portion 3422 cooperate to make the inner lining assembly 32 abut against the cylinder body 311. The structure is simple, easy to operate, and has a low cost.

[0188] Furthermore, the garment handling drum 30 also includes a waterproof component, which is disposed on the outer peripheral wall of the drum body 311 and covers the fastening assembly 34.

[0189] Specifically, by providing a waterproof component on the outer peripheral wall of the tubing 311, it is possible to further prevent moisture in the clothing processing chamber 314 from flowing to the outside of the tubing 311 through the fastening assembly 34, thereby affecting the safety of the clothing processing tubing 30.

[0190] It should be understood that in this embodiment, the waterproof component includes an adhesive layer and a water-absorbing layer, which are not shown in the figures. The water-absorbing layer is a foamed sponge, optionally in a plate-like structure, and is fixed to the outer peripheral wall of the cylinder 311 by adhesive bonding. Specifically, the adhesive layer is a structure formed after the glue has cured, achieving a seamless connection between the water-absorbing layer and the outer peripheral wall of the cylinder 311.

[0191] It should be noted that the foam sponge has functions such as water absorption, flame retardancy, and sound absorption. On the one hand, it helps to reduce the contact between external dust or air and the fastening component 34, thus reducing the corrosion of the fastening component 34. On the other hand, it can absorb and reduce the noise generated by clothing hitting the lifting component 33, which helps to further improve the performance of the clothing handling drum 30. Moreover, even if liquid accidentally flows into the drum body 311, it can be absorbed and stored by the foam sponge and then evaporate, which helps to improve the safety of the clothing handling drum 30.

[0192] In addition to partial coverage, waterproof components can also be used for full coverage. Furthermore, besides waterproofing, waterproof components can also possess the aforementioned flame-retardant and sound-absorbing functions; this application does not impose any restrictions on these aspects.

[0193] Furthermore, such as Figure 4 and Figure 8 As shown, the plate-shaped part is provided with a second clearance hole 324, and the lifting component 33 is provided with a limiting post 331. The limiting post 331 passes through the second clearance hole 324 and abuts against the cylinder body 311.

[0194] Specifically, by providing a second clearance hole 324 on the plate-shaped component and a limiting post 331 adapted to the second clearance hole 324 on the lifting assembly 33, on the one hand, the installation of the lifting component can be limited, so as to facilitate the connection and fixation between the first fastener 341 and the mounting post 332; on the other hand, the setting of the limiting post 331 can cooperate with the cylinder body 311 to prevent the lifting component from causing squeezing damage to the plate-shaped component.

[0195] It should be understood that the second clearance hole 324 is provided on the plate-shaped member. In this embodiment, the second clearance hole 324 and the first clearance hole 322 are spaced apart and staggered along the axial direction of the cylinder body 311. Correspondingly, the lifting member is provided with mounting posts 332 and limiting posts 331 arranged in a sequentially spaced and staggered manner. This not only facilitates the processing and manufacturing of the lifting member, but also effectively ensures the structural strength of the lifting member. Optionally, the second clearance hole 324 is set as a rectangular structure, and the length direction of the second clearance hole 324 is the axial direction of the cylinder body 311. This arrangement ensures that the plate-shaped member and the lifting member will not move circumferentially along the cylinder body 311, while ensuring that the lifting member has a certain adjustment space and ensuring the reliability of the installation.

[0196] In other embodiments of this application, the inner lining assembly 32 includes a plurality of plate-shaped members with identical structures, and the plurality of plate-shaped members cover the inner peripheral wall of the cylinder body 311. The sum of the arc lengths of all the plate-shaped members is less than or equal to the circumference of the inner peripheral wall of the cylinder body 311. Optionally, the plurality of plate-shaped members are arranged at intervals along the circumference of the cylinder body 311. Meanwhile, the lifting assembly 33 includes a plurality of lifting members, and at least a portion of the lifting members are disposed at the junction of two adjacent plate-shaped members, simultaneously pressing the two plate-shaped members together. Optionally, three plate-shaped members are provided, and the three plate-shaped members are arranged at intervals along the circumference of the cylinder body 311. A gap region 321 is formed between two adjacent plate-shaped members. The number of lifting members is the same as the number of plate-shaped members, and each lifting member can cover the gap region 321 and simultaneously press two plate-shaped members together.

[0197] It should be understood that the width of the interval region 321 along the circumference of the cylinder body 311 is 2mm to 12mm, for example, 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, etc. This size range ensures that the lifting member can reliably press the ends of the plate-like members on both sides of the interval region 321, and also facilitates the avoidance of the connection part 3421 between the lifting member and the cylinder body 311.

[0198] The above-mentioned garment processing tube 30 is manufactured using the following method, which includes the following steps.

[0199] S10: The metal plate is wound around once, and the two ends of the metal plate are fastened together at the joints along the winding direction to obtain the cylinder body 311. For example, the joints can be riveted or welded.

[0200] S20: The plate-shaped component of the composite structure is wound, wherein the plate-shaped component of the composite structure includes at least a first layer 325 and a second layer 326, which are stacked. The first layer 325 is located on the innermost side of the plate-shaped component of the composite structure along the winding direction, and the second layer 326 is located on the outermost side of the plate-shaped component of the composite structure along the winding direction. That is, the structure of the plate-shaped component of the composite structure after winding is the inner liner assembly 32, which is a pre-assembled whole independent of the cylinder body 311. This facilitates the separate manufacture of the cylinder body 311 and the inner liner assembly 32.

[0201] S30: The structure, which is a composite plate structure, is wound into the cylinder 311. That is, the inner lining component 32 is placed into the cylinder 311, and under its own tension, it can abut against the cylinder 311 to achieve basic positioning.

[0202] S40: Connect the lifting component to the cylinder body 311, and press the coiled composite plate structure to the cylinder body 311 using the lifting component. In other words, the installation of the inner lining is completed after the lifting component is installed.

[0203] The above-mentioned manufacturing method of the clothing treatment drum 30 has simple assembly steps and enables the clothing treatment drum 30 to have a good noise reduction effect.

[0204] like Figures 1 to 11 As shown, the second aspect of this application proposes a garment processing device 100, which includes a drying assembly 40 and a garment processing drum 30. The drying assembly 40 includes a drying air duct, and the garment processing drum 30 is configured as described above. The drying air duct is connected to the garment processing chamber 314 of the garment processing drum 30.

[0205] Specifically, taking a clothes dryer as an example, the drying air duct is connected to the clothes processing chamber 314 inside the clothes processing drum 30, and is used to introduce airflow into the clothes processing chamber 314. The clothes dryer can be used to dry clothes.

[0206] Since the garment processing drum 30 does not need to come into contact with water, the inner lining component 32 will basically not be soaked in water. This reduces the requirements for the waterproof and corrosion-resistant properties of the inner lining component 32, lowers the chance of damage to the noise reduction layer, and extends the service life of the inner lining component 32.

[0207] The location of the outlet of the drying air duct is not limited. For example, in some embodiments, the outlet of the air duct is located on the end cap, and the airflow of the air duct enters the garment processing chamber 314 through the outlet on the end cap.

[0208] In some embodiments, the airflow within the clothing handling chamber 314 can be discharged into a duct to the indoor or outdoor environment.

[0209] In other embodiments, the inlet and outlet of the drying air duct are connected to the garment handling chamber 314 to form a circulating air duct.

[0210] For example, the dryer includes a front support located at the front end of the drum 31 to support the clothes handling drum 30. The inlet of the drying air duct is located on the front support. That is, the airflow in the clothes handling chamber 314 enters the drying air duct through the inlet on the front support, undergoes condensation and dehumidification in the drying air duct, is then heated, and the heated airflow re-enters the clothes handling chamber 314 from the outlet of the air duct, thus circulating.

[0211] In addition, the garment processing device 100 includes a housing 10, a door 20, a drying assembly 40, and a garment processing drum 30. The drying assembly 40 and the garment processing drum 30 are respectively disposed inside the housing 10, and the door 20 is pivotally connected to the housing 10. The door 20 is used to open or close the garment processing chamber 314.

[0212] In the garment processing device 100 of this application, when processing garments, the garments are placed in the garment processing chamber 314 of the garment processing cylinder 30. During the processing of the garments, hard objects (zippers, buttons, etc.) on the garments collide with the first layer 325. By using the inner lining component 32 as a barrier, the transmission of noise to the outside is reduced, thereby improving the user experience.

[0213] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
