Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of clothes processing, and in particular to an inner drum cover and clothes processing equipment. BACKGROUND

[0002] The inner drum of clothes processing equipment is one of the core components of the device, mainly responsible for functions such as washing and dehydration of clothes. The inner drum is usually composed of a front cover, a drum body, and a rear cover. The front cover is the opening part of the inner drum, which is usually a fixed ring structure tightly connected to the top end of the drum body. The drum body is the main part of the inner drum, which is a cylindrical structure used to contain clothes, water, and detergent. The rear cover is the closed part of the inner drum, which is tightly connected to the bottom end of the drum body. The main function of the rear cover is to seal the bottom end of the drum body to prevent water and foam from leaking and to protect the internal mechanical components.

[0003] In related technologies, the wavy front cover has high strength in mechanics due to its unique structural design. The wave pattern can disperse and absorb more impact force, thereby improving overall durability. However, during the manufacturing process, the wavy inner drum cover faces some technical challenges. One of the main problems is the formation of a suspended area. The suspended area refers to the fact that, during the forming process, due to the particularity of the wavy structure, the plate material in some areas cannot fully contact the mold, resulting in a lack of sufficient support for the plate material in these areas during forming, which can cause cracking of the inner drum cover during the processing process. CONTENT OF THE UTILITY MODEL

[0006] a cover body having two surfaces arranged opposite to each other along a first direction, the cover body comprising a wave structure undulating along a second direction, the first direction and the second direction being arranged at an angle, and the wave structure comprising a first wave valley extending circumferentially along the cover body; and

[0007] a plurality of convex structures arranged on the first wave valley at intervals, and the convex structures being arranged protruding relative to the wave bottom of the first wave valley.

[0008] In some embodiments, the first wave valley comprises a plurality of wave valleys arranged at intervals along the second direction, and a first wave peak is formed between two adjacent first wave valleys.

[0009] In some embodiments, along the second direction, the convex structures on two adjacent first wave valleys are at least partially misaligned.

[0010] In some embodiments, along the circumferential direction of the corrugated structure, two adjacent convex structures are separated by a concave structure.

[0011] In some embodiments, along the circumferential direction of the corrugated structure, two adjacent convex structures are separated by a concave structure.

[0012] In some embodiments, the corrugated structure continuously extends along the circumferential direction of the cover body and forms a closed loop.

[0013] In some embodiments, along the circumferential direction of the corrugated structure, multiple convex structures are uniformly arranged, and the number of convex structures on two adjacent first valleys is the same.

[0014] In some embodiments, the highest point of the convex structure is not higher than the peak of the adjacent first peak.

[0015] In some embodiments, the end surface of the convex structure away from the wave bottom is a plane, the peak of the first peak is a plane, and the plane of the convex structure is flush with the plane of the adjacent first peak.

[0016] In some embodiments, the wave bottom of the first valley is a plane.

[0017] In some embodiments, the plane has a radial width d, and the d satisfies: 0mm < d ≤ 10mm.

[0018] In some embodiments, the second direction is the radial direction of the cover body, and along the radial direction pointing to the center of the cover body, the wavelength of the corrugated structure gradually decreases; and / or

[0019] The amplitude of the corrugated structure gradually increases.

[0020] In some embodiments, the corrugated structure further includes a first peak extending along the circumferential direction of the cover body, the first peak is connected to the first valley along the second direction, and the back side of the first peak forms a second valley.

[0021] In some embodiments, multiple convex structures are also arranged on the second valley, and the convex structures are arranged protruding relative to the wave bottom of the valley.

[0022] In some embodiments, along the second direction, the convex structure on the first valley and the convex structure on the second valley are at least partially misaligned.

[0023] In some embodiments, the cover body and the convex structure are integrally formed.

[0024] In another aspect, embodiments of the present application provide a laundry treating apparatus, comprising:

[0025] an inner tub including a tub body; and

[0026] The inner tub cover according to any one of the above is disposed at a front end of the tub body.

[0027] a cabinet, the inner tub being rotatably disposed in the cabinet.

[0028] The inner tub cover in embodiments of the present application includes a cover body and a convex structure, the cover body including two surfaces disposed opposite to each other in a first direction, the first direction being an axial direction of the cover body, and the cover body further including a corrugated structure undulating in a second direction, the second direction being a direction perpendicular to the first direction. The corrugated structure is designed to effectively disperse stress when the inner tub cover is subjected to external pressure, thereby improving the anti-deformation capability of the inner tub cover. The wavy design also increases the rigidity of the inner tub cover, thereby avoiding deformation and damage due to eccentric load during operation.

[0029] Further, a plurality of convex structures are spaced apart on the first valley, the convex structures reducing the overhanging area during the forming of the inner tub cover, making it easier to flow the plate material, making it easier to fill the mold, and avoiding local wall thickness thinning and cracking due to poor flow of the plate material. The plate material can be in full contact with the mold to obtain better support, thereby reducing the risk of cracking. By improving the forming performance of the inner tub cover, the scrap rate can be reduced, the production efficiency can be improved, and the production cost can be reduced.

[0038] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application will be further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and do not limit the present application.

[0039] The present application provides a kind of clothes processing equipment (figure is not shown), clothes processing equipment refers to the equipment for washing and drying clothes in family and laundry, and removes the wrinkle on clothes.It includes multiple types, such as washing machine, dryer, washing / dryer, clothes care machine and steam ironing machine etc..The main function of clothes processing equipment is to provide clothes cleaning and care solution, to keep clothes clean and neat by different programs and functions, such as washing, rinsing, dewatering and drying.

[0040] The embodiment of the present application takes a drum washing machine as a specific application example for illustration, and the technical scheme is also applicable to other types of clothes processing equipment, for example, dryer, washing-drying machine, etc..Other types of clothes processing equipment can be adjusted and improved according to their own structure and functional characteristics, referring to the present embodiment.

[0041] Clothes processing equipment includes cabinet (figure is not shown) and inner cylinder, inner cylinder is rotatably arranged in cabinet, cabinet is the shell of clothes processing equipment, usually made of metal or plastic, which can provide support and protection for its internal structure, to prevent it from being damaged by external factors.While the inner cylinder is a rotatable cylindrical structure, which is used to contain clothes, water and detergent to achieve washing and drying of clothes.

[0042] Please refer to Figure 1The inner tub includes a tub body (not shown), the inner tub cover 100, and an inner tub rear cover (not shown). The tub body is a main part of the inner tub, which is a cylindrical structure for accommodating laundry, water, and detergent. The inner tub cover 100 is arranged at the front end of the tub body and is an annular structure. Correspondingly, the inner tub rear cover is arranged at the rear end of the tub body, and the main function of the inner tub rear cover is to seal the inner tub, prevent water and foam from leaking, and maintain the internal pressure of the washing machine.

[0043] Referring to Figure 1 and Figure 2 Further, the inner tub cover 100 includes a cover body 10 and a plurality of convex structures 20. The cover body 10 is an annular structure that can be arranged on the tub body and has two surfaces arranged in opposite directions along a first direction CC. It should be noted that the two surfaces include an inner surface 10a facing the tub body and an outer surface 10b facing away from the tub body, i.e., the first direction CC can be the axial direction of the cover body 10. The cover body 10 includes a corrugated structure 11 undulating along a second direction DD. Here, the propagation direction of the corrugated structure 11 is the second direction DD, and the first direction CC and the second direction DD are arranged at an angle. In this application, the "second direction DD" refers to any radial direction of the cover body 10 arranged at an angle to the first direction CC (axial direction of the cover body 10). Specifically, the radial direction of the cover body 10 can be infinite, but the "second direction DD" refers to the propagation direction of the corrugated structure 11 among these radial directions. Therefore, although the radial direction of the cover body 10 is infinite, the undulating direction of the corrugated structure 11 (i.e., the second direction DD) extends along a specific radial direction. In other words, the second direction DD is one or more radial directions of the cover body 10, and is not limited to a unique radial direction, but is a specific direction determined according to the layout and design requirements of the corrugated structure 11.

[0044] In this application, the "first direction CC" and the "second direction DD" are reference directions for describing the spatial relationship between the corrugated structure 11 and the cover body 10. The first direction CC can be the axial direction of the cover body 10, and the second direction DD can be the radial direction of the cover body 10, but the application is not limited thereto. In other embodiments, the first direction CC and the second direction DD can be two directions arranged at an angle or perpendicular to each other. The specific definition of the first direction CC and the second direction DD can be adjusted according to actual application and design requirements, and is not limited to the axial direction and the radial direction of the cover body 10.

[0045] In the first direction CC (axial direction of the cover body 10), the cross section of the corrugated structure 11 is wavy, that is, the vibration direction of the corrugated structure 11 is the axial direction of the cover body 10, and the wavy cross section can effectively disperse the stress applied to the structure. Therefore, compared with a flat structure, the corrugated structure 11 can distribute the stress along the curve of the corrugation when bearing external loads, thereby reducing the local stress concentration phenomenon. The corrugated structure 11 is designed so that the cover body 10 can effectively disperse stress when bearing external pressure, increasing the overall deformation resistance. And the corrugated structure 11 can significantly improve the strength and durability without increasing the thickness of the material. This design enables the material to more effectively utilize its physical properties when under load, achieving better mechanical properties.

[0046] Due to the complex corrugated structure 11 of the inner cylinder cover 100, in the side wall area of the corrugated structure 11, the material is prone to form a suspended area during molding due to lack of sufficient support, causing the inner cylinder cover 100 to be prone to cracking, resulting in increased production cost and reduced production efficiency.

[0047] When viewed in any direction toward the surface, the corrugated structure 11 includes a first valley 111 extending in the circumferential direction of the cover body 10. Understandably, the present embodiment does not limit the direction in which the first valley 111 is formed. When viewed from the direction of the inner surface 10a, the corrugated structure 11 can have a first valley 111 with a cross section of the type "∩", and when viewed from the direction of the outer surface 10b, the corrugated structure 11 can have a first valley 111 with a cross section of the type "∪". It should be noted that the present embodiment does not limit the specific form, size or number of the first valley 111.

[0048] Please continue to refer to Figure 1 and Figure 2 And a plurality of convex structures 20 are arranged at intervals on the first valley 111, and the convex structure 20 can be arranged on the inner surface 10a of the inner cylinder cover 100 or on the outer surface 10b, that is, the convex structure 20 can be arranged on any single side of the inner cylinder cover 100. And the convex structure 20 is convexly arranged relative to the bottom of the first valley 111. During the molding process of the inner cylinder cover 100, the convex structure 20 helps to reduce or eliminate molding defects caused by uneven material flow, reduce the suspended area during the molding process of the inner cylinder cover 100, guide the material to flow more uniformly to each part of the mold, provide more support, so that the material flows more easily and fills during molding, reducing molding defects, thereby improving the integrity of the molding. And a plurality of convex structures 20 are arranged at intervals along the circumferential direction of the corrugated structure 11, which can guide the plastic or other molding materials to flow more uniformly in the mold, thereby filling every corner of the corrugated structure 11, and helping the material to flow in a larger range, which means that a larger size or more complex shape of the corrugated structure 11 can be molded without sacrificing the integrity of the molding.

[0049] It should be noted that the first trough 111 can include one or multiple, which are arranged at intervals along the second direction DD, and the first peak 112 is arranged between any two adjacent first troughs 111. Understandably, the greater the height difference between the first peak 112 and the first trough 111, the smaller the radius of curvature of the corrugated structure 11, which makes the corrugated structure 11 provide better mechanical support when subjected to external force, disperse and absorb more impact force, thereby improving the overall strength of the structure. However, the corrugated structure 11 with a large height difference requires the material to have better flowability so as to be able to fill the area between the peaks and troughs. If the flowability of the material is insufficient, it may cause defects in the molding process, resulting in a suspended area, which reduces the molding performance of the inner barrel cover 100. The plurality of convex structures 20 arranged in the first trough 111 can provide additional support points, which helps to reduce the formation of suspended areas during the molding process.

[0050] In some embodiments, the wavelength of the corrugated structure 11 gradually decreases along the radial direction pointing to the center of the cover body 10. Since the center of the cover body 10 has the pouring port 100a of the inner barrel, the pouring port 100a is usually a stress concentration area. By reducing the wavelength of the corrugated structure 11, the strength and impact resistance of the central area are improved.

[0051] In some embodiments, the amplitude of the corrugated structure 11 gradually increases along the radial direction pointing to the center of the cover body 10, that is, the greater the height difference of the corrugated structure, the higher the strength, which provides stronger structural support, especially in the central area, which helps to resist external pressure and impact.

[0052] Through simulation tests, the inventors confirmed that after adding the convex structure 20 in the design of the corrugated front cover, the overall strength of the structure was not affected and still maintained the original high strength. Although the convex structure 20 was added, the stiffness (ability to resist deformation) of the front cover only decreased slightly, by about 3%. This indicates that the convex structure 20 has little effect on overall stiffness. The design improvement of the convex structure 20 significantly enhances the molding performance of the inner barrel cover 100, which means that the material is easier to be molded into the required shape during the manufacturing process, improving production efficiency and quality. Without the convex structure 20, in order to ensure that the inner barrel cover 100 has a high molding rate during the molding process and avoids molding defects such as cracking, sagging or underfilling, it is usually necessary to increase the wall thickness. The purpose of increasing the wall thickness is to improve the flowability of the material and the stability during the molding process, so as to ensure that the molded part meets the strength and stiffness requirements. By adding the convex structure 20, the maximum wall thickness reduction rate is reduced, which means that while maintaining the structural strength, the amount of material used can be reduced, and the total wall thickness can be reduced by 8%. This not only saves material costs, but also can reduce the weight of the product and improve energy efficiency.

[0053] The corrugated structure 11 is continuous and in a closed loop along the circumference of the cover body 10, and the continuous and closed loop corrugated structure 11 can uniformly distribute stress in the entire circumferential direction of the inner cylinder cover 100, reducing local stress concentration and improving the overall strength and durability of the structure. The closed loop design increases the overall stability of the structure, so that the inner cylinder cover 100 is not prone to deformation when subjected to external forces, maintaining the stability of shape and size.

[0054] In addition, the cover body 10 and the convex structure 20 are integrally formed, and the integrally formed structure can reduce the connection points, thereby reducing potential weak points and improving the strength and durability of the overall structure. The inner cylinder cover 100 is more mechanically robust and can withstand greater loads and impact forces.

[0055] Please refer to Figure 3 , Figure 4 and Figure 5 In some embodiments, the highest point of the convex structure 20 is not higher than the wave crest of the adjacent first wave peak 112, i.e. the convex structure 20 is arranged in the first wave valley 111, and the adjacent first wave peak 112 includes the first wave peak 112 on the two sides of the first wave valley 111. It is worth noting that the highest point of the convex structure 20 is controlled to be not higher than the wave crest of the lower one of the two first wave peaks 112. By limiting the height of the convex structure 20, the instability of the structure caused by the excessively high protrusion is avoided, and the stability of the inner cylinder cover 100 during high-speed rotation is ensured.

[0056] Further, the bottom of the first wave valley 111 is a plane, i.e. the original circular arc shape at the corrugated portion is changed to a plane, and the plane designed bottom of the first wave valley 111 significantly improves the friction between the plate and the mold, which helps the plate to flow more smoothly into the mold, improving the molding efficiency. The surface contact mode effectively promotes the flow of materials, reduces the resistance in the molding process, and makes the plate more easily fill each part of the mold. By optimizing the contact mode, the minimum wall thickness of the part is successfully increased, thereby enhancing the overall strength and durability of the part and reducing the risk of cracking. Since the plate can be more evenly distributed during molding, this design effectively avoids the problem of part cracking caused by uneven wall thickness, ensuring the quality and service life of the product.

[0057] Please continue to refer to Figure 3 , Figure 4 and Figure 5 wherein the plane has a radial width d, d satisfies: 0mm < d ≤ 10mm, when d is greater than 1cm, i.e. the height is reduced too much, resulting in a decrease in the height difference of the corrugated structure 11, affecting the overall strength of the inner cylinder cover 100, and 0mm < d ≤ 10mm, which improves the molding rate of the corrugated structure 11 without excessively weakening the strength of the inner cylinder cover 100.

[0058] Further, the end face of the convex structure 20 away from the wave bottom is a plane, and the wave top of the first wave peak 112 is a plane, the plane of the convex structure 20 is flush with the plane of the adjacent first wave peak 112, the plane design is helpful for uniform flow of material during forming, reducing defects such as wrinkles, cracks, etc. caused by uneven forming. And the design of the plane end face simplifies the complexity of the mold, reduces the cost and difficulty of mold manufacturing, and at the same time improves the durability of the mold.

[0059] As shown in Figure 3 , Figure 4 and Figure 5 , in some embodiments, along the second direction DD, the convex structures 20 on the adjacent two first wave valleys 111 are at least partially misaligned, and it can be understood that along the radial direction of the cover body 10, the convex structures 20 on the adjacent two first wave valleys 111 can be partially misaligned, or completely misaligned. Assuming that the radially adjacent two convex structures 20 are not misaligned, then multiple convex structures 20 will be arranged in the same radial direction, which will cause uneven feeding of the sheet metal in different radial directions (with convex structures 20, without convex structures 20). This is because during the forming process, the material needs to flow and fill the corrugated shape in the mold, and if there is no misaligned convex structure 20, the material may be underfilled in some areas and overfilled in other areas. And because the resistance and support of the material during flow are different, the sheet metal at the single-sided convex structure 20 will have less deformation, and the sheet metal at the single-sided corrugation will have more deformation. Due to the deformation difference, the sheet metal at the single-sided corrugation has a higher wall thickness reduction rate, which means that the material in these areas is stretched too much, resulting in a thinner wall thickness. A higher wall thickness reduction rate will increase the stress concentration of the material, thereby increasing the risk of cracking.

[0060] The misaligned convex structure 20 makes the feeding more uniform, reduces the deformation difference, breaks the straight stress transmission path caused by the continuous wave valley, interrupts the straight transmission of stress in the radial direction, reduces the risk of cracking and breaking, reduces the wall thickness reduction rate, and thus improves the forming quality and durability of the part.

[0061] As shown in Figure 3 , Figure 4 and Figure 5As shown, in some embodiments, along the circumferential direction of the corrugated structure 11, the concave structure 1111 is arranged between two adjacent convex structures 20, and one of the first valleys 111 has a convex structure 20, and the other first valley 111 has a concave structure 1111. Understandably, along the extension direction of the first valley 111, the convex structure 20 and the concave structure 1111 are arranged alternately, so that the corrugated structure 11 also presents a wave shape in the circumferential direction, which helps to more evenly distribute stress, reduce local stress concentration, enhance the bending stiffness of the inner cylinder cover 100, and make it more solid when subjected to bending force, not easy to deform, thereby improving the durability and crack resistance of the inner cylinder cover 100. Optimize the force transmission path so that the force can be transmitted more evenly to the entire structure rather than concentrated in a certain point.

[0062] The convex structure 20 and the concave structure 1111 are arranged opposite to each other along the second direction DD, and have the same central angle. On the one hand, the convex and concave structures 1111 with the same central angle can provide a more regular and beautiful appearance, and on the other hand, due to the alternating arrangement of the convex and concave structures 1111, the material can flow and distribute more evenly during molding, avoiding excessive stretching or compression in a single direction, which helps to achieve more uniform wall thickness distribution during molding and enhances the stability of the overall structure.

[0063] As shown in Figure 3 , Figure 4 and Figure 5 , in some embodiments, along the circumferential direction of the corrugated structure 11, a plurality of convex structures 20 are uniformly spaced, and the number of convex structures 20 on the adjacent two first valleys 111 is the same. Uniformly spaced convex structures 20 help to more evenly distribute the load acting on the inner cylinder cover 100, reduce local stress concentration, and symmetrically arranged convex structures 20 increase the symmetry of the inner cylinder cover 100, which helps to balance the centrifugal force generated by the inner cylinder when rotating at high speed, and reduce vibration and noise.

[0064] It should be noted that the number of convex structures 20 on one first valley 111 can be 8, 9, 10, and in other embodiments, the number can be more or less, which is not limited by the present application.

[0065] In some embodiments, the corrugated structure 11 further comprises a first wave crest 112 extending circumferentially along the cover body 10, the first wave crest 112 being connected with the first wave trough 111 along the second direction DD, a back side of the first wave crest 112 forming a second wave trough, and a plurality of convex structures 20 being further arranged on the second wave trough in a spaced manner, and the convex structures 20 being arranged in a convex manner relative to the wave bottom of the wave trough. The arrangement of the convex structures 20 on the second wave trough helps to achieve more uniform material filling during the forming process of the inner cylinder cover 100, reduces the lack of material in the suspended area, and can better control the material flow and reduce the uneven change of wall thickness during the forming process. Understandably, in the present embodiment, the inner surface 10a and the outer surface 10b of the corrugated structure 11 of the inner cover front cover are both provided with the convex structures 20 described above, and the height, number and shape of the convex structures 20 in the second wave trough can be adapted according to the convex structures 20 in the first wave trough 111.

[0066] Further, along the second direction DD, the convex structures 20 on the first wave trough 111 and the convex structures 20 on the second wave trough are at least partially arranged in a staggered manner. The staggered arrangement of the convex structures 20 on the first wave trough 111 and the second wave trough makes the feeding more uniform during the manufacturing of the inner cylinder cover 100, reduces the deformation difference, breaks the straight stress transmission path caused by the continuous wave trough, interrupts the straight stress transmission in the radial direction, reduces the risk of cracking and breaking, reduces the wall thickness reduction rate, and thus improves the forming quality and durability of the part.
