Description

Technical Field

[0001] The present application belongs to the technical field of kitchen appliances, and in particular relates to a cooking appliance. Background Art

[0002] There are many types of cooking utensils on the market, and the market competition is relatively fierce. As people's requirements for product appearance are increasing, more and more cooking utensils will appropriately add decorative parts to improve the aesthetics. Of course, the addition of decorative parts can also improve some functions of cooking utensils, such as not easy to change color, easy to clean, etc.

[0003] Taking rice cookers as an example, some rice cooker products will add decorative parts to the middle ring of the rice cooker to enhance the appearance of the product. Most of the existing decorative parts are made of metal. In order to enhance the structural strength of the outer edge of the metal decorative parts, avoid scratches on the edge of the metal decorative parts, and avoid the outer edge of the metal decorative parts from warping during assembly, the outer edge of the metal decorative parts is generally folded. The folding process is generally to fold the folded edge of the outer edge back to the bottom, that is, the folded edge formed by the folding of the outer edge is in contact with the upper surface of the metal decorative part. This folding method is likely to produce a large stress on the folded edge of the metal decorative part, resulting in a circle of folding marks on the outer surface of the metal decorative part, affecting the appearance quality of the product. In addition, if the force is improperly applied during the folding process, it is easy to cause the folding edge and the outer edge of the metal decorative part to break, and cause the metal decorative part to have a reduced fit with the middle ring at this position, and foreign impurities are easy to enter the matching gap between the two, affecting the user's experience. Utility Model Content

[0004] The present application provides a cooking utensil to solve the technical problem that the overlapped edge structure of the existing middle ring decorative piece generates obvious stress marks between the overlapped edge and the outer peripheral edge of the decorative piece.

[0005] The technical solution adopted in this application is:

[0006] A cooking utensil comprises a pot body, wherein the pot body comprises an outer cover shell, a middle ring arranged on the top of the outer cover shell, and a metal decorative part arranged above the middle ring, wherein the metal decorative part comprises a decorative sheet and an overlapped edge formed by bending downward along the outer periphery of the decorative sheet, wherein a bending spacing is provided between the overlapped edge and the outer periphery of the decorative sheet, and an anti-overlapping gap is provided between the end of the overlapped edge and the lower surface of the decorative sheet, and the spacing of the anti-overlapping gap is not greater than the bending spacing.

[0007] The cooking appliance in the present application also includes the following additional technical features:

[0008] The end of the overlapped edge is provided with a flat portion, and the anti-overlapping gap is formed between the flat portion and the lower surface of the decorative sheet.

[0009] The metal decorative part further includes a connecting portion connecting the decorative sheet and the overlapped edge, and the overlapped edge extends upwardly obliquely relative to the connecting portion, so that the bending spacing is greater than the spacing of the anti-overlapping gap.

[0010] The metal decorative part also includes a fixing portion which is arranged at the end of the overlapped edge and extends downward; the middle ring is provided with a slot which is adapted to the fixing portion, and the lower portion of the fixing portion is bent relative to the middle ring to be hooked on the middle ring.

[0011] The metal decorative part also includes a fixing portion arranged at the end of the overlapped edge and extending downward; the metal decorative part also includes a connecting portion connecting the decorative sheet and the overlapped edge, and the overlapped edge extends upwardly inclined relative to the connecting portion to form a space between the overlapped edge and the middle ring.

[0012] The metal decorative part further includes a connecting portion connecting the decorative sheet and the overlapped edge, and an extending length of the connecting portion in the up-down direction is greater than a thickness of the decorative sheet.

[0013] The middle ring includes a concave platform for supporting the decorative sheet and a top flange connected to the concave platform and extending upward, and the upper surface of the decorative sheet is not higher than the upper edge of the top flange.

[0014] The middle ring is provided with a convex rib extending upward to abut against the lower surface of the decorative sheet, and a heat dissipation gap is formed between the middle ring and the position of the decorative sheet that is not abutted against the middle ring.

[0015] The pot body also includes a cover plate, the inner periphery of the metal decorative piece is clamped and fixed between the cover plate and the middle ring, the cover plate and the decorative sheet have abutment positions, and the convex ribs are misaligned with the abutment positions.

[0016] The pot body also includes a cover plate, the inner periphery of the metal decorative piece is clamped and fixed between the cover plate and the middle ring, the cover plate and the decorative sheet have abutment positions, and the middle ring is provided with a downwardly recessed groove corresponding to the abutment positions.

[0017] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0018] 1. In the present application, there is a bending gap between the overlapped edge of the metal decorative part and the outer periphery of the decorative sheet. Due to the existence of the bending gap, the relative folded portion of the overlapped edge and the decorative sheet is moved down a certain distance relative to the decorative sheet. Compared with the technical solution of directly folding the outer periphery of the decorative sheet at a large angle, the stress at the outer periphery of the decorative sheet can be greatly reduced, thereby reducing or even eliminating the overlap marks at the outer periphery of the decorative sheet, thereby improving the appearance quality of the metal decorative part. Moreover, an anti-overlap gap is provided between the end of the overlapped edge and the lower surface of the decorative sheet in the present application. On the one hand, the folding angle of the overlapped edge in the present application is smaller than the folding angle of the overlapped edge that is folded to the bottom in the prior art, which further reduces the stress concentration at the connection between the overlapped edge and the outer periphery of the decorative sheet, and reduces or even eliminates the stress marks between the overlapped edge and the outer periphery of the decorative sheet. On the other hand, the bending spacing and the anti-overlap gap complement each other, that is, the existence of the bending spacing lays the foundation for the existence of the anti-overlap gap, and the existence of the anti-overlap gap provides a guarantee for the continuation of the bending spacing between the overlapped edge and the outer periphery of the decorative sheet. The two cooperate with each other so that the folded metal decorative part can maintain a certain thickness to meet the requirements of structural strength, and prevent the outer periphery of the decorative sheet from producing obvious overlap marks and reducing the appearance quality. Furthermore, it can also avoid breakage at the connection between the overlapped edge and the outer periphery of the decorative sheet due to excessive stress, thereby ensuring the fit between the two after the metal decorative part is assembled to the middle ring.

[0019] 2. As a preferred embodiment of the present application, a flat portion is provided at the end of the overlapped edge, and an anti-overlap gap is formed between the flat portion and the lower surface of the decorative sheet. Since the overlapped edge is formed by folding the outer edge of the metal decorative piece inward, during the folding process, the end of the overlapped edge will be close to the lower surface of the decorative sheet. The provision of the flat portion can cooperate with the bending spacing to further ensure the existence of the anti-overlap gap, thereby further avoiding the overlap caused by the end of the overlapped edge abutting against the lower surface of the decorative sheet, thereby improving the appearance quality of the metal decorative piece and the grade of the product.

[0020] 3. As a preferred embodiment of the present application, a connecting portion is provided between the decorative sheet and the folded edge, and the extending length of the connecting portion in the up and down directions is greater than the thickness of the decorative sheet, thereby ensuring the existence of the bending spacing, and through the size design of the connecting portion, the scope of the bending stress in the folding process can be further reduced, and the stress marks at the connecting position between the connecting portion and the outer periphery of the decorative sheet and at the connecting position between the connecting portion and the folded edge can be reduced, which can not only improve the appearance quality of the metal decorative parts, but also realize the stable support of the metal decorative parts on the middle ring.

[0021] Furthermore, the angle between the connecting portion and the decorative sheet is less than or equal to 90°, so that the connecting position of the connecting portion and the overlapped edge is located within the projection range of the decorative sheet on the middle ring, thereby preventing a large gap from being generated between the outer periphery of the decorative sheet and the middle ring, and greatly reducing the probability of external impurities entering between the middle ring and the outer periphery of the decorative sheet.

[0022] 4. As a preferred embodiment of the present application, the overlapped edge extends upwardly at an angle relative to the connecting portion, and the bending spacing is greater than the spacing of the anti-overlapping gap. During the manufacturing process, the overlapped edge is continuously bent and formed relative to the connecting portion. When the processing is completed and the bending force disappears, the overlapped edge has a tendency to rebound relative to the connecting portion. In this embodiment, the overlapped edge is set to extend upwardly at an angle relative to the connecting portion, so that after the metal decorative part is processed and manufactured, even if the overlapped edge rebounds, the connecting portion will not be significantly reversely bent, thereby reducing the scope affected by the rebound of the overlapped edge, avoiding the occurrence of reverse creases or warping at the connection position between the connecting portion and the metal decorative part, and ensuring the appearance quality of the metal decorative part. Furthermore, such a setting can reduce the overall thickness of the metal decorative part on the one hand, which is conducive to the miniaturization design of the pot body. On the other hand, the overlapped edge extends upwardly at an angle, reducing or even avoiding the mutual interference between the overlapped edge and the middle ring, achieving a stable support for the metal decorative part on the middle ring, avoiding the compression deformation of the decorative sheet, and ensuring the stability of the metal decorative part after assembly.

[0023] 5. As a preferred embodiment of the present application, a fixing portion is provided at the end of the overlapped edge, and a slot adapted to the fixing portion is provided in the middle ring, thereby providing a rough positioning for the installation of the metal decorative part, which helps to improve the assembly efficiency of the metal decorative part installed on the middle ring. Moreover, the fixing portion is fixed to the end of the overlapped edge, which can simplify the structural design of the metal decorative part, reduce the difficulty of processing the metal decorative part, make the structural integrity of the metal decorative part stronger, and help to improve the processing and manufacturing speed and the qualified rate after processing. In addition, in order to improve the appearance of the product, the decorative sheet is mostly a thin sheet structure. The traditional method of forming a hook on the clamping rib and a buckle on the clamping groove to achieve the snap-fit ​​between the two through the hook and the buckle is not easy to achieve on the decorative sheet. In this embodiment, the lower part of the fixing portion is bent relative to the middle ring to be hooked on the middle ring, which not only reduces the processing difficulty of the decorative sheet, but also helps to improve the assembly efficiency between the metal decorative part and the middle ring.

[0024] In addition, the existence of the fixing part and the fixing method of bending the fixing part relative to the middle ring to hook on the middle ring enable the fixing part to pull the end of the overlapped edge, thereby ensuring the stable existence of the anti-overlapping gap and the appearance quality of the decorative part.

[0025] 6. As a preferred embodiment of the present application, the metal decorative part also includes a fixing portion arranged at the end of the overlapped edge and extending downward, the metal decorative part also includes a connecting portion connecting the decorative sheet and the overlapped edge, the overlapped edge extends upwardly inclined relative to the connecting portion to form an avoidance gap between the overlapped edge and the middle ring, the existence of the avoidance gap provides movement space for the rebound of the overlapped edge during assembly, effectively preventing the decorative sheet from warping due to resistance in the rebound of the overlapped edge caused by the pulling of the fixing portion, thereby improving the adaptive adjustment function of the product after assembly and ensuring the yield of the product after assembly.

[0026] 7. Metal decorative parts are generally made of metal materials. During the operation of cooking utensils, the temperature of the metal decorative parts will increase due to factors such as heat transfer. Therefore, as a preferred embodiment of the present application, the middle ring is provided with a convex rib extending upward to abut against the lower surface of the decorative sheet, so that a heat dissipation gap can be formed between the position where the decorative sheet is not abutted against the middle ring and the middle ring. The existence of the heat dissipation gap facilitates the heat dissipation of the metal decorative parts during use, which not only avoids the metal decorative parts from rising to a higher temperature and affecting the user experience, but also reduces the heat transfer from the metal decorative parts to the middle ring, thereby extending the service life of the middle ring.

[0027] In addition, the middle ring supports the decorative sheet through the convex ribs, achieving a small area of ​​contact between the middle ring and the decorative sheet. Therefore, to ensure the flatness of the decorative sheet after assembly, it is only necessary to ensure the flatness of the upper surface of the convex ribs. The surface area of ​​the upper surface of the convex ribs is relatively small, and precision assurance is easy to achieve and the cost is relatively low.

[0028] 8. As a preferred embodiment of the present application, the pot body also includes a cover plate, the inner periphery of the metal decorative part is clamped and fixed between the cover plate and the middle ring, the cover plate and the decorative piece have abutting positions, and the convex ribs and the abutting positions are mutually offset. With such an arrangement, the decorative piece can be suspended below the portion opposite to the first abutting position, so that the contact between the cover plate and the decorative piece changes from the original rigid contact to the current elastic space, so that when there is a local unevenness in the portion corresponding to the decorative piece and the cover plate, the gap between the cover plate and the circumference of the decorative piece can be eliminated by pressing down the cover plate, avoiding the situation where the part of the area where the metal decorative piece contacts the cover plate has been stuck, while the other part still has a large gap, so that after assembly, the assembly gap between the cover plate and the metal decorative piece is more uniform, which improves the appearance quality, and also greatly reduces the probability of the metal decorative piece not being assembled in place.

Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0047] like Figures 1 to 5 As shown, a cooking utensil includes a pot body, which includes an outer cover shell 4, a middle ring 1 arranged on the top of the outer cover shell 4, and a metal decorative part 2 arranged above the middle ring 1, the metal decorative part 2 includes a decorative sheet 21 and a folded edge 23 formed by bending downward along the outer periphery of the decorative sheet 21, a bending spacing 28 is provided between the folded edge 23 and the outer periphery of the decorative sheet 21, and an anti-fold mark gap 24 is provided between the end of the folded edge 23 and the lower surface of the decorative sheet 21, and the spacing of the anti-fold mark gap 24 is not greater than the bending spacing 28.

[0048] It should be noted that the present application does not specifically limit the form of the overlapped edge 23. For example, in one embodiment, the overlapped edge 23 is parallel to the decorative sheet 21; in another embodiment, the overlapped edge 23 is inclined and extends in a direction close to the decorative sheet 21. As long as there is an anti-overlap gap 24 between the overlapped edge 23 and the lower surface of the decorative sheet 21, technicians in this field can make a choice based on actual conditions.

[0049] In the present application, there is a bending spacing 28 between the overlapped edge 23 of the metal decorative part 2 and the outer periphery of the decorative sheet 21. Due to the existence of the bending spacing 28, the relative folded portion of the overlapped edge 23 and the decorative sheet 21 is moved down a certain distance relative to the decorative sheet 21. Compared with the technical solution of directly folding the outer periphery of the decorative sheet 21 at a large angle, the stress at the outer periphery of the decorative sheet 21 can be greatly reduced, thereby reducing or even eliminating the overlap marks at the outer periphery of the decorative sheet 21, thereby improving the appearance quality of the metal decorative part 2. Moreover, an anti-folding gap 24 is provided between the end of the overlapped edge 23 and the lower surface of the decorative sheet 21 in the present application. On the one hand, the folding angle of the overlapped edge 23 in the present application is smaller than the folding angle of the overlapped edge that is folded to the bottom in the prior art, which further reduces the stress concentration at the connection portion 22 of the overlapped edge 23 and the outer peripheral edge of the decorative sheet 21, and reduces or even eliminates the stress marks between the overlapped edge 23 and the outer peripheral edge of the decorative sheet 21. On the other hand, the bending spacing 28 and the anti-folding gap 24 complement each other, that is, the existence of the bending spacing 28 lays the foundation for the existence of the anti-folding gap 24. The existence of the anti-fold mark gap 24 provides a guarantee for the existence of the bending spacing 28 between the folded edge 23 and the outer periphery of the decorative sheet 21. The two cooperate with each other so that the folded metal decorative part 2 can maintain a certain thickness to meet the structural strength requirements, and prevent the outer periphery of the decorative sheet 21 from producing obvious fold marks and reducing the appearance quality. Furthermore, it can also avoid the connection position between the folded edge 23 and the outer periphery of the decorative sheet 21 due to excessive stress. Fracture, thereby ensuring the fit between the metal decorative part 2 after the two are assembled to the middle ring 1.

[0050] like Figure 4 As shown, the anti-overlapping gap 24 is a, and a satisfies 0.1 mm≦a≦1 mm, so as to prevent overlapping marks from occurring on the outer periphery of the decorative sheet 21 and optimize the overall thickness of the metal decorative part 2 .

[0051] As a preferred embodiment of the present application, Figure 4 As shown, a flat portion 27 is provided at the end of the overlapped edge 23, and the anti-overlap gap 24 is formed between the flat portion 27 and the lower surface of the decorative sheet 21. Since the overlapped edge 23 is formed by folding the outer edge of the metal decorative piece inward, during the folding process, the end of the overlapped edge 23 will be close to the lower surface of the decorative sheet 21. The arrangement of the flat portion 27 can cooperate with the bending spacing 28 to further ensure the existence of the anti-overlap gap 24, thereby further avoiding the overlap caused by the end of the overlapped edge abutting against the lower surface of the decorative sheet, thereby improving the appearance quality of the metal decorative piece and the grade of the product.

[0052] Furthermore, the metal decorative part 2 also includes a fixing portion 25 connected to the flat portion 27 and extending downward. The existence of the flat portion 27 enlarges the angle between the fixing portion 25 and the overlapped edge 23, reducing the stress concentration phenomenon at the connection position between the fixing portion 25 and the overlapped edge 23. Moreover, in the embodiment where the fixing portion 25 is bent relative to the middle ring 1 to be hooked on the middle ring 1, the fixing portion 25 will pull the overlapped edge 23 during the bending process. The provision of the flat portion 27 can alleviate the scope of the pulling, reduce the migration of the fixing portion 25 to the side of the overlapped edge 23 away from the flat portion 27 during the bending process, thereby avoiding the reverse fold at the outer peripheral edge of the decorative sheet 21, and ensuring the appearance quality of the decorative sheet 21.

[0053] As a preferred embodiment of the present application, Figure 1 and Figure 2 As shown, the metal decorative part 2 also includes a connecting portion 22 connecting the decorative sheet 21 and the overlapped edge 23, and the extending length of the connecting portion 22 in the up-down direction is greater than the thickness of the decorative sheet 21. The size design of the connecting portion 22 ensures the existence of the bending spacing 28, which can further reduce the scope of the bending stress during the overlapped edge, reduce the stress marks at the connecting position of the connecting portion 22 and the outer peripheral edge of the decorative sheet 21, and at the connecting position of the connecting portion 22 and the overlapped edge 23, which can not only improve the appearance quality of the metal decorative part 2, but also realize the stable support of the metal decorative part 2 on the middle ring 1.

[0054] As a preferred embodiment of the present embodiment, the angle between the connecting portion 22 and the decorative sheet 21 is less than or equal to 90°, so that the connection position of the connecting portion 22 and the overlapping edge 23 is located within the projection range of the decorative sheet 21 on the middle ring 1, thereby preventing a large gap from being generated between the outer periphery of the decorative sheet 21 and the middle ring 1, and greatly reducing the probability of external impurities entering between the middle ring 1 and the outer periphery of the decorative sheet 21.

[0055] Furthermore, if Figure 2 As shown, the angle between the connecting portion 22 and the decorative sheet 21 is 90°. Of course, due to the existence of processing errors, the angle between the two is close to 90° after actual production and processing. The angle between the two is 90° or close to 90°, which can achieve the optimal solution between the two results of reducing the assembly gap between the decorative sheet 21 and the middle ring 1 and reducing or even eliminating the stress mark between the decorative sheet 21 and the connecting portion 22.

[0056] As a preferred example under this embodiment, the connection position of the connecting portion 22 and the overlapped edge 23 abuts against the middle ring 1. On the one hand, the connection between the two can enable the metal decorative part 2 to be stably supported on the middle ring 1. On the other hand, when the overlapped edge 23 rebounds under force, the abutting position can hinder the rebound of the overlapped edge 23, thereby preventing the rebound from extending to the connection position of the connecting portion 22 and the decorative sheet 21, thereby avoiding the occurrence of reverse creases or warping at the connection position of the connecting portion 22 and the metal decorative part 2, thereby ensuring the appearance quality of the metal decorative part 2.

[0057] As a preferred embodiment of the present application, Figure 2 As shown, the metal decorative part 2 also includes a connecting portion 22 connecting the decorative sheet 21 and the overlapped edge 23, and the overlapped edge 23 extends upwardly obliquely relative to the connecting portion 22, so that the bending spacing 28 is greater than the spacing of the anti-overlapping gap 24. During the manufacturing process, the overlapped edge 23 is continuously bent relative to the connecting portion 22. When the processing is completed and the bending force disappears, the overlapped edge 23 has a tendency to rebound relative to the connecting portion. In this embodiment, by setting the overlapped edge 23 to extend upwardly obliquely relative to the connecting portion 22, after the processing and manufacturing of the metal decorative part 2 is completed, even if the overlapped edge 23 rebounds, it will not cause a large reverse bending of the connecting portion 22, thereby reducing the range affected by the rebound of the overlapped edge, avoiding the phenomenon of reverse folding or warping at the connection position between the connecting portion 22 and the metal decorative part, and ensuring the appearance quality of the metal decorative part 2. Furthermore, such a configuration can, on the one hand, reduce the overall thickness of the metal decorative part 2, which is conducive to the miniaturization design of the pot body; on the other hand, the overlapping edge 23 extends upwardly and tilts, thereby reducing or even avoiding the mutual interference between the overlapping edge 23 and the middle ring 1, thereby achieving a stable support for the metal decorative part 2 on the middle ring 1, avoiding the decorative sheet 21 from being compressed and deformed, and ensuring the stability of the metal decorative part 2 after assembly.

[0058] Furthermore, if Figure 2 As shown, the angle between the connecting portion 22 and the decorative sheet 21 is 90°, and the overlapped edge 23 extends upwardly obliquely relative to the connecting portion 22, so that the anti-overlapping gap 24 gradually decreases from the side of the overlapped edge 23 close to the connecting portion 22 to the side of the overlapped edge 23 away from the connecting portion 22, and a structure with an open end (the end of the overlapped edge 23 away from the connecting portion 22 is not in contact with the decorative sheet 21) and a cross-section that is approximately a right triangle is formed between the decorative sheet 21, the connecting portion 22 and the overlapped edge 23.

[0059] As a preferred embodiment of the present application, Figure 2 and Figure 6As shown, the metal decorative part 2 also includes a fixing portion 25 disposed at the end of the overlapped edge 23 and extending downward. The fixing portion 25 is fixed to the end of the overlapped edge 23, which can simplify the structural design of the metal decorative part 2, reduce the difficulty of processing the metal decorative part 2, make the structural integrity of the metal decorative part 2 stronger, and help improve the processing and manufacturing speed and the qualified rate after processing.

[0060] Furthermore, if Figure 7 As shown, the middle ring 1 is provided with a slot 13 adapted to the fixing portion 25, so as to provide rough positioning for the metal decorative part 2 during the assembly process of the metal decorative part 2 and the middle ring 1, thereby improving the assembly efficiency of the metal decorative part 2. In order to improve the appearance of the product, the decorative sheet 21 is mostly a thin sheet structure. The traditional method of forming a hook on the clamping rib and a buckle on the clamping groove to achieve the snap-fit ​​between the hook and the buckle is not easy to achieve on the decorative sheet 21. Therefore, as a preferred embodiment, reference Figure 2 The lower part of the fixing part 25 is bent relative to the middle ring 1 to be hooked on the middle ring 1. By bending the lower part of the fixing part 25 relative to the middle ring 1 to be hooked on the middle ring 1, not only the processing difficulty of the decorative sheet 21 is reduced, but also the assembly efficiency between the metal decorative part 2 and the middle ring 1 is improved.

[0061] In addition, the existence of the fixing portion 25 and the fixing method in which the fixing portion 25 is bent relative to the middle ring 1 to be hooked on the middle ring 1 enable the fixing portion 25 to pull the end of the overlapped edge 23, thereby ensuring the stable existence of the anti-overlap gap 24 and the appearance quality of the decorative part 2.

[0062] As a preferred embodiment of the present application, the outer periphery of the decorative sheet 21 is provided with a folded edge 23, and a plurality of fixing portions 25 are provided on the folded edge 23. In contrast, the middle ring 1 is provided with slots 13 having the same number and one-to-one correspondence as the fixing portions 25. By providing a plurality of fixing portions 25, the middle ring 1 and the metal decorative part 2 can be connected and positioned at multiple points, thereby improving the stability and reliability of the connection between the metal decorative part 2 and the middle ring 1. In addition, the decorative sheet 21 can be tightened and fixed to the upper surface of the middle ring 1 through the multi-point connection between the two, thereby improving the fit between the decorative sheet 21 and the middle ring 1, thereby improving the appearance effect after the two are assembled.

[0063] As a preferred embodiment of the present application, Figure 2 and Figure 6As shown, the metal decorative part 2 also includes a fixing portion 25 disposed at the end of the overlapped edge 23 and extending downward; the metal decorative part 2 also includes a connecting portion 22 connecting the decorative sheet 21 and the overlapped edge 23, and the overlapped edge 23 extends upwardly at an angle relative to the connecting portion 22, so as to form an escape gap 26 between the overlapped edge 23 and the middle ring 1. The existence of the escape gap 26 provides a movement space for the rebound of the overlapped edge 23 during the assembly process, effectively preventing the overlapped edge 23 from being pulled back by the fixing portion 25 and causing the decorative sheet 21 to warp, thereby improving the adaptive adjustment function of the product after assembly and ensuring the yield rate of the product after assembly.

[0064] Of course, it can be understood that in some alternative embodiments, the middle ring 1 is provided with a protruding abutting bevel, and the folded edge 23 abuts against the abutting bevel to achieve support and positioning of the folded edge 23 through the abutting bevel.

[0065] As a preferred embodiment of the present application, Figure 2 As shown, the middle ring 1 includes a concave platform 11 carrying a decorative sheet 21 and a top flange 12 connected to the concave platform 11 and extending upward, and the upper surface of the decorative sheet 21 is not higher than the upper edge of the top flange 12. By providing the concave platform 11, on the one hand, it can provide rough positioning for the installation of the metal decorative part 2 and improve the installation efficiency of the metal decorative part 2. On the other hand, it can realize the internal placement of the metal decorative part 2 and avoid the external convex arrangement of the metal decorative part 2. Taking the cooking utensil as an electric rice cooker or a pressure cooker as an example, such an arrangement can avoid the exposure of the metal decorative part 2 when the pot cover is closed to the pot body, improve the consistency and aesthetics of the appearance of the electric rice cooker or the pressure cooker, and thus improve the appearance quality of the product.

[0066] Furthermore, the outer side surface of the connecting portion 22 abuts against the inner side elevation of the recessed platform 11 to reduce the gap between the decorative sheet 21 and the middle ring 1, thereby preventing the accumulation of external bacteria, impurities, etc. at the joint between the two, thereby reducing the cleaning burden of the user and improving the user experience.

[0067] The metal decorative part 2 is generally made of metal material. During the operation of the cooking utensil, factors such as heat transfer may cause the temperature of the metal decorative part 2 to rise. Therefore, as a preferred embodiment of the present application, Figure 3As shown, the middle ring 1 is provided with a convex rib 14 extending upward to abut against the lower surface of the decorative sheet 21, and a heat dissipation gap is formed between the position where the decorative sheet 21 does not abut against the middle ring 1 and the middle ring 1. The existence of the heat dissipation gap facilitates the heat dissipation of the metal decorative part 2 during use, which not only prevents the metal decorative part 2 from rising to a higher temperature and affecting the user's experience, but also reduces the heat transfer from the metal decorative part 2 to the middle ring 1, thereby extending the service life of the middle ring 1. In addition, the middle ring 1 supports the decorative sheet 21 through the convex rib 14, so that the middle ring 1 and the decorative sheet 21 have a small area of ​​contact. Therefore, in order to ensure the flatness of the decorative sheet 21 after assembly, it is only necessary to ensure the flatness of the upper surface of the convex rib 14, and the surface area of ​​the upper surface of the convex rib 14 is relatively small, so the precision guarantee is easy to achieve and the cost control of the precision is relatively low. In addition, the setting of the convex rib 14 can also improve the structural strength of the middle ring 1 and prevent the middle ring 1 from being deformed by force or heat.

[0068] Furthermore, the convex ribs 14 are evenly distributed along the circumference of the upper part of the middle ring 1 to achieve uniform support for the inner circumference of the decorative sheet 21. The height of the convex ribs 14 is H, and H satisfies: 0.05mm≦H≦1mm, so as to meet the heat dissipation requirements and make the convex ribs 14 fit the bending spacing to achieve stable support of the decorative sheet 21 on the middle ring 1.

[0069] As a preferred embodiment of this implementation, Figure 3 , Figure 6 and Figure 7 As shown, the pot body further includes a cover plate 3, the inner periphery of the metal decorative part 2 is clamped and fixed between the cover plate 3 and the middle ring 1, the cover plate 3 and the decorative sheet 21 have abutting positions, and the ribs 14 are offset from the abutting positions.

[0070] Such an arrangement can make the decorative piece 21 suspended below the part opposite to the abutting position, so that the contact between the cover plate 3 and the decorative piece 21 changes from the original rigid contact to the current one with a certain elastic space, so that when there is local unevenness in the part corresponding to the decorative piece 21 and the cover plate 3, the gap around the cover plate and the decorative piece can be eliminated by pressing down the cover plate 3, avoiding the situation where part of the area where the metal decorative part 21 contacts the cover plate 3 is already stuck, while another part still has a large gap, so that after assembly, the assembly gap between the cover plate 3 and the metal decorative part 2 is more uniform, which improves the appearance quality, and also greatly reduces the probability of the metal decorative part not being properly assembled.

[0071] As a preferred embodiment of the present application, refer to Figure 3 , Figure 6 and Figure 7The pot body also includes a cover plate 3, the inner periphery of the metal decorative piece 2 is clamped and fixed between the cover plate 3 and the middle ring 1, the cover plate 3 and the decorative sheet 21 have abutting positions, and the middle ring 1 is provided with a downwardly recessed groove 15 corresponding to the abutting position. The provision of the groove 15 can also make the decorative sheet 21 suspended below the portion opposite to the abutting position, so that the assembly gap between the cover plate 3 and the metal decorative piece 2 is more uniform.

[0072] Preferably, the middle ring 1 is provided with a convex rib 14 extending upward to abut against the lower surface of the decorative sheet 21, the convex rib 14 is offset from the abutting position, and the middle ring 1 is provided with a downwardly recessed groove 15 corresponding to the abutting position, thereby further improving the uniformity of the assembly gap.

[0073] Of course, in one example, the contact position between the cover plate 3 and the decorative sheet 21 may also be opposite to the position of the convex rib 14 , and a groove 15 recessed away from the decorative sheet 21 is provided on the convex rib 14 , which is not limited here.

[0074] Preferably, in the above embodiment, Figure 3 As shown, the width L1 of the groove 15 can be further made larger than the width L2 of the cover plate 3 at the contact position between the cover plate 3 and the decorative sheet 21, so as to further improve the effect of pressing down the cover plate 3 to eliminate the gap around the decorative sheet.
