[0138] The pot body 10 can comprise a shell assembly and a base 400 located at the lower side of the shell assembly. The lower end of the shell assembly can be connected with the base 400 by any suitable manner, such as clamping, plug-in, fastening by fasteners such as screws, etc. The pot body 10 is generally in the shape of a rectangular prism with rounded corners, and has a cylindrical inner pot receiving portion. The pot body 10 comprises an inner pot, which can be freely put into or taken out of the inner pot receiving portion, so as to facilitate cleaning of the inner pot. The inner pot is usually made of metal material, and is used for containing materials to be heated, such as rice, soup, etc.

[0139] Referring to Figures 1 to 3 , Figures 12 to 15The shell assembly includes a shell body 100 and a decorative band 200. The shell assembly can be made of different materials to meet different requirements. For example, the shell body 100 is made of plastic or plastic material. The decorative band 200 is made of metal material. The shell body 100 provides basic structural support, and the overall quality of the shell assembly is light. The decorative band 200 gives the cooking utensil a more upscale and delicate appearance while effectively resisting deformation and damage, which can increase the overall firmness and durability. The shell body 100 and the decorative band 200 can be fixed by buckling. After connection, some additional fastening measures are needed, such as bending the inserted ear, or using screws, rivets and other fasteners to further fix the decorative band 200. The assembly process is complex and the assembly efficiency is low.

[0140] Referring to Figures 1 to 3 , Figures 6 to 10 , Figures 12 to 15 In this scheme, the shell body 100 includes a first side and a second side arranged opposite to each other along the thickness direction thereof, and a mounting hole 101 penetrating the first side and the second side. The first side is used to face the outer side of the pot body 10, and the second side is used to face the inner side of the pot body 10. The mounting hole 101 is used to cooperate with the decorative band 200 to be connected.

[0141] Referring to Figures 1 to 5 , Figures 12 to 15 The decorative band 200 is a preformed structure, and the decorative band 200 includes a body portion 210 and a plug-in portion 220 connected to each other. The plug-in portion 220 includes an extension portion 221 and a clamping portion 222. The first end of the extension portion 221 is connected to the body portion 210, and the extension portion 221 is arranged at an angle with the body portion 210. The clamping portion 222 is connected to the second end of the extension portion 221, and the clamping portion 222 is arranged at an angle with the extension portion 221. In the state that the decorative band 200 is installed in place, the body portion 210 is located at the first side, the clamping portion 222 is located at the second side, and at least part of the extension portion 221 is located in the mounting hole 101.

[0142] Through the shell assembly provided by the scheme, the plug-in portion 220 of the decorative band 200 can be directly plugged into the mounting hole 101 and directly clamped with the shell body 100 through the clamping portion 222, so that subsequent fastening process is not needed. The scheme reduces the manufacturing cost and the installation cost, improves the assembly efficiency, and reduces the maintenance cost caused by loosening or damage of the fastener. By arranging the body portion 210 and the clamping portion 222 of the decorative band 200 on different sides of the shell body 100, not only the firm connection of the decorative band 200 and the shell body 100 is ensured, but also the stability of the overall structure of the shell assembly is enhanced.

[0143] In the present solution, the body part 210 and the insertion part 220 of the decorative band 200 form a "H" shaped structure or a "Z" shaped structure. The decorative band 200 has at least two folding angles, wherein the "H" shaped structure refers to a rectangular frame structure with one end opening. The "Z" shaped structure refers to a structure with continuous folding or bending. The clamping part 222 extends in a first direction. The first direction is the same as the up-down direction of the cooking appliance. The insertion part 220 can be directly inserted into the mounting hole 101 to realize assembly, so the size of the mounting hole 101 is matched with the size of the clamping part 222. The size of the mounting hole 101 in the up-down direction is greater than the size of the clamping part 222 in the up-down direction, so as to ensure that the insertion part 220 can be inserted into the mounting hole 101 without obstacles.

[0144] The ratio of the size of the mounting hole 101 in the up-down direction to the size of the clamping part 222 in the up-down direction is greater than or equal to 1.1:1. By accurately controlling the size ratio of the mounting hole 101 and the clamping part 222, it can be ensured that the insertion part 220 can be smoothly inserted into the mounting hole 101. The ratio is set to be greater than 1, which allows for small errors in the manufacturing and assembly process while ensuring installation accuracy.

[0145] The size d1 of the clamping part 222 in the up-down direction is greater than or equal to 1.5 mm, so as to ensure that a stable clamping connection can be formed with the shell body 100 after insertion. d1 can be, but is not limited to, 1.5 mm, 2 mm, 3 mm, 5 mm.

[0146] The shell body 100 further comprises a first edge 102, and the mounting hole 101 is spaced apart from the first edge 102 in the up-down direction. The first edge 102 is used to connect with the base 400. Two groups of insertion parts 220 are clamped to the mounting hole 101 and the first edge 102, respectively. Through the clamping action of the two groups of insertion parts 220, the connection stability between the decorative band 200 and the shell body 100 can be further enhanced, preventing loosening or falling off during use.

[0147] Optionally, the extension parts 221 of the two groups of insertion parts 220 extend in a direction away from each other. The clamping part 222 close to the base 400 extends away from the mounting hole 101, that is, extends towards the base 400, and the clamping part 222 can be clamped to the inner surface of the base 400. Therefore, the clamping part 222 can better contact the base 400 after installation, forming a more stable support.

[0148] On the basis of the above-mentioned embodiments, the mounting hole 101 has oppositely arranged first hole wall 1011 and second hole wall 1012, the first hole wall 1011 is closer to the first edge 102 than the second hole wall 1012, and the insertion part 220 is clamped to the second hole wall 1012. In assembly, the insertion part 220 is first inserted into the mounting hole 101, at which time the extension part 221 is close to the first hole wall 1011, and after the clamping part 222 passes through the mounting hole 101, the extension part 221 can be moved towards the second hole wall 1012. Then, by appropriate adjustment and positioning, the clamping part 222 of the insertion part 220 is tightly clamped on the second hole wall 1012. Alternatively, in the state that the clamping part 222 of the insertion part 220 is tightly clamped on the second hole wall 1012, another set of insertion parts 220 are clamped to the first edge 102.

[0149] Alternatively, the first edge 102 is formed with a notch 103, and the insertion part 220 is located at the notch 103. The notch 103 provides the necessary insertion space for the insertion part 220. The side wall of the notch 103 can also form a better fixed fitting structure with the base 400.

[0150] The body part 210 includes a decorative band body 211 and a folded edge 212 connected to the edge of the decorative band body 211, and the folded edge 212 is arranged at an angle to the decorative band body 211. The design of the folded edge 212 can increase the overall structural strength of the decorative band 200, making it more durable.

[0151] On the basis of the above-mentioned embodiments, the folded edge 212 is clamped to the first edge 102. The cooperation of the folded edge 212 and the first edge 102 can achieve the limiting of the decorative band 200 in the upward direction along the up-down direction. At least part of the folded edge 212 is located between the first edge 102 and the base 400. The cooperation of the folded edge 212 and the base 400 can achieve the limiting of the decorative band 200 in the downward direction along the up-down direction.

[0152] On the basis of the above-mentioned embodiments, the first side is formed with a stepped portion 120, and the design of the stepped portion 120 provides a stable clamping point for the folded edge 212. The folded edge 212 is clamped to the stepped portion 120, and the cooperation of the folded edge 212 and the stepped portion 120 can achieve the limiting of the decorative band 200 in the upward direction along the up-down direction.

[0153] It can be understood that the insertion part 220 extends from the first side to the second side at the first edge 102 and the stepped portion 120, and the insertion part 220 is also adapted to cooperate with the first edge 102 and the stepped portion 120 to limit the decorative band 200 in the up-down direction.

[0154] The stepped portion 120 includes a first stepped surface 121 and a second stepped surface 122. The first stepped surface 121 and the second stepped surface 122 both extend along the up-down direction of the pot body 10. The first stepped surface 121 is used to cooperate with the body portion 210 of the decorative band 200. The second stepped surface 122 is recessed relative to the first stepped surface 121, and at least part of the mounting hole 101 is formed in the second stepped surface 122. The decorative band body 211 overlaps the first stepped surface 121. The folded edge 212 extends from the body portion 210 to the second stepped surface 122, that is, the folded edge 212 overlaps between the first stepped surface 121 and the second stepped surface 122. Through the cooperation of the second stepped surface 122 and the folded edge 212, a more definite positioning reference can be provided for the installation of the decorative band 200, thereby improving the assembly precision and efficiency.

[0155] The wall thickness d2 at the first stepped surface 121 is greater than or equal to 1.5 mm. The wall thickness d3 at the second stepped surface 122 is greater than or equal to 0.6 mm. Reasonable wall thickness settings, on the premise of ensuring the structural stability of the shell body 100, are provided with structures connected with the decorative band 200, so that the transition and cooperation between the shell body 100 and the decorative band 200 are reasonable, to ensure the overall aesthetics and coordination. d2 can be but is not limited to 1.5 mm, 2 mm, 3 mm, 5 mm. d3 can be but is not limited to 0.6 mm, 1 mm, 2 mm, 3 mm.

[0156] In the present scheme, the decorative band 200 further includes a bendable portion 230, which can be bent to be clamped on the second side in the state that the decorative band 200 is assembled in place. Through the bending and clamping of the bendable portion 230, the connection stability between the decorative band 200 and the shell body 100 or other connecting components can be further enhanced. The bendable portion 230 can be made of a sheet material and has a certain elasticity and toughness. Appropriate creases or smaller bending portions with a certain width and / or thickness can be provided at the bending portions, so as to facilitate the bending of the bendable portion 230.

[0157] On the basis of the above-mentioned embodiments, the bendable portion 230 is clamped on the first edge 102. Alternatively, after the decorative band 200 is assembled to the shell body 100, the bendable portion 230 is bent towards the side away from the base 400. Thus, when the base 400 is not installed, the decorative band 200 is tightly combined with the shell body 100 at the first edge 102, ensuring that there is no large gap or opening at the combined portion between the decorative band 200 and the shell body 100, so that the installation and disassembly process of the base 400 is more convenient.

[0158] On the basis of the above-mentioned embodiments, the bendable portion 230 is clamped on the mounting hole 101. During assembly, the bendable portion 230 is only needed to be clamped into the mounting hole 101, and then the bendable portion 230 is bent, so that the installation of the decorative band 200 is completed.

[0159] In the above embodiment, the bending direction of the bendable portion 230 is opposite to the extending direction of the clamping portion 222. That is, in the state that the decorative band 200 is assembled to the shell body 100, the bendable portion 230 and the clamping portion 222 are clamped to the shell body 100 and the base 400 along the up-down direction respectively, or are clamped to the upper periphery and the lower periphery of the fixing hole respectively. In the present scheme, the insertion portion 220 has a shape and size matched with the shell body 100, so that the insertion portion 220 and the shell body 100 can be accurately and stably clamped together during the assembly of the decorative band 200. The bendable portion 230 is bent after the decorative band 200 is assembled in place, further strengthening the connection between the decorative band 200 and the shell body 100. Through the clamping of the bendable portion 230 and the clamping portion 222 in the up-down direction, a more stable connection structure can be formed to prevent the decorative band 200 from loosening or falling off due to uneven stress or external impact during use.

[0160] Optionally, the bendable portion 230 and the clamping portion 222 are arranged at intervals along the circumferential direction. Through the interval arrangement, the connection between the decorative band 200 and the shell body 100 is strengthened.

[0161] Optionally, the bendable portion 230 is located at the front side, the rear side, the left side and the right side of the pot body 10. By arranging the bendable portion 230 around the pot body 10, it can be ensured that the decorative band 200 can be closely attached to the shell body in each direction, avoiding misalignment or loosening.

[0162] Optionally, the number of the bendable portion 230 arranged on the edge of the decorative band 200 close to the first edge 102 of the shell body 100 is large, so as to ensure that there is no large gap or opening between the decorative band 200 and the shell body 100.

[0163] In the present scheme, the mounting hole 101 has oppositely arranged first hole wall 1011 and second hole wall 1012, and the first hole wall 1011 is closer to the first edge 102 than the second hole wall 1012. The insertion portion 220 is clamped to the second hole wall 1012. The bendable portion 230 is clamped to the first hole wall 1011.

[0164] As known from the foregoing, the size of the mounting hole 101 is adapted to the size of the clamping portion 222, that is, the distance between the first hole wall 1011 and the second hole wall 1012 is slightly larger than the size of the clamping portion 222. Due to the large distance of the mounting hole 101, the insertion portion 220 can enter relatively easily during assembly of the decorative band 200. Since the distance between the first hole wall 1011 and the second hole wall 1012 is much larger than the thickness of the extending portion 221, the mounting hole 101 cannot well limit the decorative band 200 during assembly.

[0165] Optionally, the clamping hole 104 is provided with an elastic clamping arm 110. The elastic clamping arm 110 includes a fixed end connected to the first hole wall 1011, and a free end extending towards and spaced from the second hole wall 1012. The at least partial extension 221 is located between the free end and the second hole wall 1012. The spacing between the free end and the second hole wall 1012 is adapted to the thickness of the clamping portion 222. The free end of the elastic clamping arm 110 can effectively limit the clamping portion 222, preventing it from shifting or shaking during use. The material of the elastic clamping arm 110 has a certain elasticity and toughness to ensure that it can maintain stable elasticity and shape during use. During assembly of the decorative band 200, when the clamping portion 222 enters the mounting hole 101, it can abut the elastic clamping arm 110. The clamping portion 222 deforms the elastic clamping arm 110 by pressing it. After passing through the mounting hole 101, the insertion portion 220 moves towards the second hole wall 1012. The extension 221 can act on the elastic clamping arm 110. After removing the external force, the elastic clamping arm 110 returns to its original state, and the extension 221 can be clamped between the elastic clamping arm 110 and the second hole wall 1012 of the mounting hole 101. The insertion portion 220 is automatically fastened under the action of the elastic clamping arm 110, without the need for additional fixing operations, thereby improving assembly efficiency.

[0166] Optionally, the shell body 100 further includes a clamping hole 104, which is in communication with the mounting hole 101 and has oppositely arranged third and fourth hole walls 1041 and 1042, with the third hole wall 1041 flush with the second hole wall 1012. At least part of the insertion portion 220 is located between the third and fourth hole walls 1041 and 1042. The spacing between the third and fourth hole walls 1041 and 1042 is adapted to the thickness of the insertion portion 220. The spacing between the third and fourth hole walls 1041 and 1042 is slightly larger than the thickness of the extension 221. By cooperating the clamping hole 104 with the extension 221, a more stable connection structure can be formed. After the insertion portion 220 is inserted into the mounting hole 101, the extension 221 is moved along the second hole wall 1012 to the third hole wall 1041, and the extension 221 can be clamped into the clamping hole 104, thereby limiting the decorative band 200. The mounting hole 101 preliminarily positions the decorative band 200, and the clamping hole 104 further limits and fixes the decorative band 200. The provision of the clamping hole 104 improves assembly accuracy and efficiency, and reduces error rate during assembly.

[0167] Optionally, the spacing d4 between the third hole wall 1041 and the fourth hole wall 1042 is 0.1-0.5 mm. The length d5 of the clamping hole 104 is greater than or equal to 2 mm. Through the setting of the size, it is ensured that the plug-in part 220 has sufficient support area in the hole, thereby improving the stability of the connection. d4 can be, but is not limited to, 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm. d5 can be, but is not limited to, 2 mm, 3 mm, 4 mm, 5 mm.

[0168] In some embodiments of the utility model, the shell assembly further includes a fixing piece 300, the end of the decorative band 200 is connected to the fixing piece 300 to form a closed ring. As shown in the figure, the fixing piece 300 is provided with a connecting hole 301, and the two ends of the decorative band 200 are provided with bendable parts 230, which are connected to the connecting hole 301. The shape, size and position of the fixing piece 300 and the connecting hole 301 should be set according to the size, shape and assembly requirements of the decorative band 200. By connecting the two ends of the decorative band 200 through the fixing piece 300, a closed ring structure can be formed, so that the decorative band 200 is more stable and is not easy to loosen or fall off. Figure 11

[0169] Optionally, the fixing piece 300 is located on the side of the decorative band 200 facing the shell main body 100. That is, the fixing piece 300 is hidden to the inside of the decorative band 200, so that the fixing piece 300 is completely blocked by the decorative band 200 when viewed from the outside, without damaging the overall aesthetics of the decorative band 200.

[0170] The shell main body 100 is provided with a mounting groove 105 suitable for accommodating the fixing piece 300. The fixing piece 300 is hidden inside the decorative band 200 and located in the mounting groove 105 of the shell main body 100, so it does not occupy additional external space. Optionally, the mounting groove 105 penetrates the wall surface of the shell main body 100, facilitating the installation of the decorative band 200 and the fixing piece 300. For example, the bendable part 230 can be bent from the inside of the pot body 10 to achieve fixed installation of the decorative band 200 and the fixing piece 300.

[0171] Optionally, the outer surface of the fixing piece is flush with the outer surface of the decorative band 200 to increase the consistency of the appearance of the cooking utensil.

[0172] According to the above scheme, the decorative band 200 can be stably installed to the shell main body 100. In the circumferential direction of the pot body 10, the shell main body 100 and the decorative band 200 partially form a double-layer shell structure. In the double-layer shell structure, the shell main body 100 and the decorative band 200 support each other to form a stable whole. This structure not only enhances the stability of the connection, but also improves the overall rigidity and stability of the pot body 10. ​

[0173] A plurality of mounting holes 101 are formed circumferentially on the shell body 100. A plurality of insertion portions 220 are formed circumferentially on the decorative band 200. By circumferentially arranging the mounting holes 101 or the insertion portions 220, the connection between the decorative band 200 and the shell body 100 can be ensured to be more stable. At the same time, only one-to-one mounting of the insertion portions 220 and the mounting holes 101 is required during installation, so that the assembly process is simple and efficient.

[0174] As described above, the shell body 100 can also be provided with an elastic clamping arm 110 in the mounting hole 101. The shell body 100 can also be provided with a clamping hole 104 in communication with the mounting hole 101. Optionally, the elastic clamping arm 110 is located on the left side and / or the right side of the pot body 10. Optionally, the clamping hole 104 is located on the front side of the pot body 10.

[0175] The clamping hole 104 can be used as a positioning during assembly of the decorative band 200, providing a clear reference point for subsequent assembly. After the front side decorative band 200 is installed, the left and right side decorative bands 200 can be more easily aligned and matched with the front side decorative band 200, thereby ensuring the accuracy and consistency of the entire assembly process.
