[0037] The present application embodiment provides a laundry treatment drum, see Figure 1 , including a barrel 10 and a noise reduction layer assembly 20.

[0038] It should be noted that the body 10 has a clothing access opening at one axial end. The clothing treatment barrel also includes an end cover, which is arranged at the other axial end of the body 10, that is, the clothing access opening and the end cover are located at opposite axial ends of the body 10.

[0039] The drum body 10 and the end cover enclose a clothes processing chamber for placing clothes. The drum body 10 and the end cover serve as the main structure of the clothes processing drum.

[0040] The noise reduction layer assembly 20 is coated on the circumferential inner surface of the barrel 10. The circumferential inner surface refers to the surface of the inner side of the barrel 10 along the radial direction. That is, the shape of the noise reduction layer assembly 20 is adapted to the shape of the barrel 10, and is roughly cylindrical.

[0041] The circumferential inner surface of the barrel 10 covered by the noise reduction layer assembly 20 means that the circumferential inner surface of the barrel 10 is covered by the noise reduction layer assembly 20, and the area of ​​the barrel 10 covered by the noise reduction layer assembly 20 does not directly contact the clothing.

[0042] The noise reduction layer assembly 20 includes a first layer structure 23 and a second layer structure 21 . The second layer structure 21 is located radially inside the first layer structure 23 of the laundry treatment tub.

[0043] It should be noted that the first layered structure 23 and the second layered structure 21 are layered and differentiated along the thickness direction of the noise reduction layer assembly 20. The approximate shape of the first layered structure 23 is a cylindrical shape surrounding the circumference of the barrel 10, and the approximate shape of the second layered structure 21 is a cylindrical shape surrounding the circumference of the barrel 10. The first layered structure 23 and the second layered structure 21 are stacked.

[0044] The first layered structure 23 is in contact with the barrel 10. That is, the first layered structure 23 is the outermost layer of the noise reduction layer assembly 20 in the radial direction.

[0045] The second layered structure 21 serves as the appearance structure of the clothes processing drum. The second layered structure 21 is exposed in the clothes processing cavity, and the user can see the second layered structure 21 through the clothes taking-in and putting-out opening.

[0046] At least one of the first layer structure 23 and the second layer structure 21 serves as a vibration-damping and noise-reducing structure. The vibration-damping and noise-reducing structure contains sound-insulating and noise-reducing materials to absorb vibration noise to a certain extent.

[0047] In the related art, a rubber strip is sleeved on the circumferential outer side of the inner cylinder to try to improve the noise. On the one hand, the rubber strip only plays a role in reducing the vibration amplitude of the cylinder body at a local position of the cylinder body. For the position where the rubber strip is not sleeved, the noise reduction effect is poor.

[0048] In the clothing treatment drum of the embodiment of the present application, since the noise reduction layer assembly 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 contacts the noise reduction layer assembly 20. When foreign objects such as buttons and zippers of the clothing hit the clothing treatment drum, the noise reduction layer assembly 20 can convert and absorb at least part of the vibration, thereby reducing the vibration amplitude transmitted to the drum body, and can suppress the generation of vibration noise to a certain extent, reduce the noise radiated outward from the clothing treatment drum, thereby achieving a higher noise reduction. In addition, the noise reduction layer assembly 20 has a large coverage area on the drum body 10, and can achieve a noise reduction effect over a wide range.

[0049] The clothing processing drum in the embodiment of the present application has a layered design for the noise reduction layer assembly 20. Under the premise of satisfying the noise reduction requirement, the industrial design flexibility of the second layer structure 21 can be improved, and the aesthetic appearance of the noise reduction layer assembly 20 can be improved. In addition, the user or operator can directly and visually observe the position, wear condition, etc. of the noise reduction layer assembly 20, which is convenient for timely maintenance and / or replacement.

[0050] It should be noted that the noise reduction layer assembly 20 covers the barrel 10 as much as possible. In some embodiments, the noise reduction layer assembly 20 covers more than 80% of the area of ​​the circumferential inner surface of the barrel 10. It should be noted that the area of ​​the circumferential inner surface of the barrel 10 does not include the area of ​​the side where the end cover faces the clothing processing chamber.

[0051] The body 10 is the main structure of the laundry treatment drum, and its material needs to ensure the structural strength of the laundry treatment drum. Exemplarily, in some embodiments, the body 10 is a metal body, that is, the body 10 is made of metal, such as stainless steel.

[0052] For example, see Figure 1 The thickness d1 of the barrel 10 is 0.3 mm to 0.7 mm (millimeter), that is, 0.3 mm ≤ d1 ≤ 0.7 mm. For example, 0.3 mm, 0.4 mm, 0.45 mm, 0.5 mm, 0.6 mm, 0.67 mm, 0.7 mm, etc. This thickness range can ensure that the barrel 10 has good structural strength and is also easy to process.

[0053] It should be noted that, unless otherwise specified, the thickness in the embodiments of the present application refers to the radial dimension of the laundry processing drum.

[0054] In some embodiments, the barrel 10 is formed by winding a metal plate, and the metal plate is fastened at the butt joints at opposite ends along the winding direction, for example, by riveting, welding, etc.

[0055] For example, after the metal plate is wound and fastened at the butt joint, one end of the barrel is contracted inward to form a necking structure. The necking structure defines a clothing loading port. The noise reduction layer assembly 20 can fully cover the circumferential inner surface of the barrel 10 outside the necking structure.

[0056] Exemplarily, the barrel 10 is an airtight structure, that is, water, air, etc. cannot pass through the barrel 10, that is, the barrel 10 is not provided with holes for water or air to circulate.

[0057] Exemplarily, the circumferential inner surface of the barrel 10 is a continuous smooth surface. In other words, the barrel 10 has no pattern, that is, no uneven structure. In this way, the noise reduction layer assembly 20 and the barrel 10 are in close contact, so that the part of the noise reduction layer assembly 20 that is used to contact with clothes is relatively flat and not easy to wear clothes.

[0058] Exemplarily, at least one of the first layered structure 23 and the second layered structure 21 is used as a support structure to generate radially outward tension on the barrel 10, so that the noise reduction layer assembly 20 can be pressed against the circumferential inner surface of the barrel 10 under the action of tension. It should be noted that the support structure not only has a certain structural strength, but also needs a certain toughness to be able to apply radially outward tension to the barrel 10.

[0059] Among them, the radially outward tension generated on the barrel 10 means that the supporting structure has a certain radially outward force on the barrel 10 due to the effect of its own material, and this force is conducive to attaching the noise reduction layer assembly 20 as a whole to the circumferential inner surface of the barrel 10, and the noise reduction layer assembly 20 as a whole is not easy to collapse or warp from the barrel 10 under the effect of its own gravity.

[0060] In this embodiment, the tension of the supporting structure is conducive to maintaining the noise reduction layer assembly 20 on the barrel 10, and is conducive to maintaining the structural shape of the noise reduction layer assembly 20. Even if the noise reduction layer assembly 20 is only partially connected to the barrel 10, the entire noise reduction layer assembly 20 can reliably lean against the circumferential inner surface of the barrel 10 and is not easy to collapse or warp from the barrel 10.

[0061] The connection method of the noise reduction layer assembly 20 and the barrel 10 is not limited, as long as the noise reduction layer assembly 20 is not easy to fall off from the barrel 10. For example, bonding, riveting, screw connection, etc.

[0062] Exemplarily, the noise reduction layer assembly 20 is detachably connected to the barrel 10. The detachable connection means that after the noise reduction layer assembly 20 is connected to the barrel 10, it can be completely removed from the barrel 10 without destroying the existing structure of the barrel 10 or the existing structure of the noise reduction layer assembly 20. Of course, after being removed, it can be repeatedly connected to the barrel 10.

[0063] In this embodiment, the noise reduction layer assembly 20 is an independent component, so that the noise reduction layer assembly 20 and the barrel body 10 can be independently manufactured during the manufacturing process, and then the two can be connected; when the noise reduction layer assembly 20 is damaged and needs to be replaced, the noise reduction layer assembly 20 on the barrel body 10 can be removed, and then a new noise reduction layer assembly 20 can be connected to the barrel body 10.

[0064] It should be noted that, since the noise reduction layer assembly 20 is arranged on the inner side of the drum body 10, the noise reduction layer assembly 20 can be disassembled and replaced without disassembling the clothes processing drum, which is simple and convenient to operate.

[0065] It should be noted that there is no limitation on the detachable connection method between the noise reduction layer assembly 20 and the barrel body 10, for example, screws, bolts, clamping, etc., which are not limited here.

[0066] Exemplarily, the clothes treatment drum includes lifting ribs, and the lifting ribs are connected to the drum body 10. Specifically, the lifting ribs are arranged on the inner side of the drum body 10. The number of the lifting ribs can be one or more.

[0067] During the rotation of the clothes treatment drum, the lifting ribs rotate with the clothes. After the clothes are lifted to a certain height, they fall again under the action of their own gravity, thereby fluffing the clothes.

[0068] Exemplarily, the lifting ribs press the noise reduction layer assembly 20 onto the circumferential inner surface of the barrel 10. That is to say, while the lifting ribs are connected to the barrel 10, the connection between the noise reduction layer assembly 20 and the barrel 10 is also realized. In this way, the connection structure of the lifting ribs can be fully utilized, and there is no need to set an additional connection structure for the noise reduction layer assembly 20 and the barrel 10, which is convenient for assembly, improves assembly efficiency, and can also simplify the connection structure between the noise reduction layer assembly 20 and the barrel 10.

[0069] In addition, the lifting rib has a relatively large area at one end facing the barrel 10, and one end of the lifting rib is pressed against the noise reduction layer assembly 20. The lifting rib and the noise reduction layer assembly 20 have a large contact area, which increases the force-bearing area of ​​the noise reduction layer assembly 20, improves the connection reliability between the noise reduction layer assembly 20 and the barrel 10, and makes the noise reduction layer assembly 20 less likely to break.

[0070] In some embodiments, the noise reduction layer assembly 20 is constructed by winding a composite plate-like structure. The end surfaces of the composite plate-like structure at two opposite ends along the winding direction are aligned and do not overlap. In this way, the thickness of each part of the noise reduction layer assembly 20 is relatively uniform.

[0071] For example, at least one of the lifting ribs extends along the joint of the composite plate-like structure and presses the joint onto the barrel 10. In this way, after the composite plate-like structure is wound once, the joint may not be connected, and the lifting rib is directly pressed against the barrel 10, which can prevent the joint from warping and omit the connection operation of the joint, which is conducive to simplifying the structure and further improving the assembly efficiency.

[0072] For example, see Figure 1 The thickness D of the noise reduction layer assembly 20 is 1.0 mm to 3.0 mm, that is, 1.0 mm ≤ D ≤ 3.0 mm. For example, 1 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.5 mm, 1.7 mm, 1.9 mm, 2.0 mm, 2.1 mm, 2.2 mm, 2.3 mm, 2.4 mm, 2.5 mm, 2.6 mm, 2.8 mm, 2.9 mm, 3.0 mm, etc. The thickness of the noise reduction layer assembly 20 is relatively thick, so that the noise reduction layer assembly 20 has corresponding structural strength and noise reduction effect.

[0073] It should be noted that, since the first layered structure 23 is in direct contact with the barrel 10, the first layered structure 23 is made of a flexible material, which can avoid rigid contact between the first layered structure 23 and the barrel 10 and has the effect of reducing vibration and noise. The first layered structure 23 can also be understood as a vibration reduction layer.

[0074] The material of the first layered structure 23 is not limited.

[0075] In some embodiments, the first layered structure 23 includes at least one of foam plastic, foam rubber, and foam silicone.

[0076] The foam plastic has the characteristics of light weight, sound absorption, vibration resistance, and corrosion resistance, which is helpful to reduce the overall weight of the clothes processing drum.

[0077] Foam plastics, also known as microporous plastics, refer to a type of polymer material formed by a large number of gas micropores dispersed in solid plastics. The whole is covered with countless interconnected or unconnected micropores. Foam plastics can be made of polyurethane (PUR), polystyrene (PS), polyvinyl chloride (PVC), polyethylene (PE), phenolic resin (PF), etc.

[0078] Foam rubber and foam silicone have good viscoelasticity and have good damping effect in terms of vibration reduction.

[0079] The material of the second layered structure 21 is not limited.

[0080] For example, in some embodiments, the second layered structure 21 includes at least one of leather and a metal layer, wherein the leather can be genuine leather or artificial leather.

[0081] Leather can be easily processed into the desired color, pattern, etc., to achieve a rich process design. In addition, leather is relatively soft and can absorb the impact and vibration of loads and foreign objects to a large extent. At the same time, leather can also show a high-end visual sense and soft care for clothes. The metal layer can be used as a structural support, and can form a large tension on the barrel 10.

[0082] Specifically, in some embodiments, the first layered structure 23 is foam plastic, and the second layered structure 21 is leather. The foam plastic, as a supporting structure, also has a certain vibration reduction effect, and the leather has a greater degree of absorption of the impact and vibration of the load and foreign objects, and the leather can show a high-end visual sense and soft care for the clothes.

[0083] In some other embodiments, the first layered structure 23 is a material with good viscoelasticity such as foamed rubber or foamed silica gel, and the second layered structure 21 is a metal layer. Foamed rubber has good viscoelasticity. The viscoelastic foam layer, as a vibration-damping and dissipating layer, can absorb the load transmitted by the metal layer and the knocking vibration energy of foreign objects to a large extent. The metal layer, as a structural support, can form a large tension on the barrel 10, and can also achieve a wear-resistant and antibacterial functional surface, which is not easily scratched by sharp parts of clothing, thereby improving the service life of the noise reduction layer assembly 20. In this embodiment, the metal layer and the barrel 10 form a sandwich structure, and the first layered structure is sandwiched between the two. Since the first layered structure 23 has good damping performance, it can achieve a good noise reduction effect.

[0084] For example, a pattern may be processed on the metal layer of the second layered structure 21 .

[0085] Exemplarily, the thickness d2 of the first layered structure 23 is 0.9 mm to 2.6 mm, that is, 0.9 mm ≤ d2 ≤ 2.6 mm, for example, 0.9 mm, 1.0 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm, 1.6 mm, 1.65 mm, 1.7 mm, 1.76 mm, 1.8 mm, 1.9 mm, 2 mm, 2.2 mm, 2.3 mm, 2.5 mm, 2.6 mm, etc.

[0086] Exemplarily, the thickness d3 of the second layered structure 21 is 0.1-0.4 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.

[0087] Exemplarily, the noise reduction layer assembly 20 includes an adhesive layer 22, which is disposed between the first layer structure 23 and the second layer structure 21, and bonds the first layer structure 23 and the second layer structure 21 together. The adhesive layer 22 serves as a carrier to achieve a gapless connection between the first layer structure 23 and the second layer structure 21, so that the first layer structure 23 and the second layer structure 21 are not easily delaminated.

[0088] The adhesive layer 22 is specifically a structure formed after the glue is cured. Specifically, during the manufacturing process, glue can be applied on one side of the first layered structure 23, or glue can be applied on one side of the second layered structure 21, or glue can be applied on 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 attached, and after the glue is cured, the first layered structure 23 and the second layered structure 21 are fixed together without a gap, and the adhesive layer 22 is formed after the glue is cured.

[0089] The specific type of glue is not limited, and a suitable glue can be selected according to the different materials of the first layered structure 23 and the second layered structure 21 .

[0090] Exemplarily, the thickness d4 of the adhesive layer 22 is 0.05 mm to 0.3 mm, that is, 0.05 mm ≤ d4 ≤ 0.3 mm, for example, 0.05 mm, 0.06 mm, 0.08 mm, 0.09 mm, 0.1 mm, 0.14 mm, 0.15 mm, 0.16 mm, 0.17 mm, 0.18 mm, 0.2 mm, 0.21 mm, 0.23 mm, 0.24 mm, 0.26 mm, 0.27 mm, 0.28 mm, 0.29 mm, 0.3 mm, etc.

[0091] An embodiment of the present application further provides a clothes drying device, comprising an air duct and a clothes processing drum of any embodiment of the present application.

[0092] The air duct is communicated with the clothes processing chamber in the clothes processing drum, and is used to introduce airflow into the clothes processing chamber. In other words, the clothes drying device can be used to dry clothes.

[0093] In this embodiment, the clothing processing drum does not need to come into contact with water, so the noise reduction layer assembly 20 is basically not soaked in water. In this way, the waterproof and anti-corrosion requirements for the material of the noise reduction layer assembly 20 can be reduced, the probability of damage to the noise reduction layer is reduced, and the service life of the noise reduction layer assembly 20 is increased.

[0094] The position of the outlet of the air duct is not limited. For example, in some embodiments, the outlet of the air duct is arranged on the end cover, and the air flow of the air duct enters the clothes processing chamber through the outlet on the end cover.

[0095] In some embodiments, the airflow in the laundry processing chamber can be discharged to indoor or outdoor through a pipeline.

[0096] In some other embodiments, the inlet and the outlet of the air duct are both connected to the clothes processing chamber to form a circulating air duct.

[0097] Exemplarily, the clothes drying device includes a front support, which is arranged at the front end of the drum body 10 and is used to support the clothes processing drum. The inlet of the air duct is arranged on the front support. That is, the airflow in the clothes processing chamber enters the air duct from the inlet on the front support, is condensed and dehumidified in the air duct, and then heated. The heated airflow enters the clothes processing chamber again from the outlet of the air duct, and the cycle continues.

[0098] The present application provides a method for manufacturing a laundry treatment drum. Figure 2 , comprising the following steps.

[0099] S1: The metal plate is wound around once, and the butt joints at the two opposite ends of the metal plate along the winding direction are fastened to obtain the barrel 10. For example, riveting, welding, etc. can be performed at the butt joints.

[0100] S2: the composite plate-like structure is wound, wherein the composite plate-like structure at least comprises a first layer structure and a second layer structure, the first layer structure and the second layer structure are stacked, wherein the first layer structure is located at the outermost side of the composite plate-like structure along the winding direction, and the second layer structure is located at the innermost side of the composite plate-like structure along the winding direction. In other words, the structure after the composite plate-like structure is wound is a noise reduction layer assembly 20, as a pre-installed whole, and the pre-installed whole is independent of the barrel 10. In this way, it is convenient to manufacture the barrel 10 and the noise reduction layer assembly 20 respectively.

[0101] S3: The structure after the composite plate-like structure is wound is placed in the barrel 10. In other words, after being placed in the barrel 10, the noise reduction layer assembly 20 can be abutted against the barrel 10 under its own tension to achieve basic positioning.

[0102] S4: connecting the lifting ribs to the barrel 10, and pressing the structure after the composite plate-like structure is wound to the barrel 10 through the lifting ribs. In other words, after the lifting ribs are installed, the installation of the noise reduction layer assembly 20 has been achieved.

[0103] The manufacturing method of the clothing processing drum in the embodiment of the present application has simple assembly steps and can make the clothing processing drum have a better noise reduction effect.
