[0103] Exemplary embodiments according to the present application will now be described in more detail with reference to the accompanying drawings. These exemplary embodiments may, however, be implemented in many different ways and should not be construed as limited to the embodiments set forth herein. It should be understood that these embodiments have been provided merely for the purposes of clarity and that the present application should not be limited in scope to these embodiments.

[0104] The present application provides a cooking appliance. The cooking appliance in the present application can be used as an electric rice cooker, an electric pressure cooker, an electric stew pot, an electric fire pot and a soybean milk machine.

[0105] The following will be described in detail Figures 1 to 19 The cooking appliance according to the present application will be described in detail.

[0106] As Figure 18 With Figure 19 As shown in the drawings, the cooking appliance in the present application comprises a cover body 20 and a pot body 10. The pot body 10 is used for cooking food, and the cover body 20 is used for covering the pot body 10, for example, the cover body 20 is connected to the pot body 10 in an openable and closable manner, and is used for covering the pot body 10. When the cover body 20 covers the pot body 10, a cooking space is formed between the cover body 20 and the pot body 10. Alternatively, when the cover body 20 covers the pot body 10, the cover body 20 is sealingly connected with the inner pot.

[0107] The cover body 20 comprises a face cover, a lining cover and a detachable cover. The face cover is located at the outermost side of the cover body 20 to constitute the outer shell of the cover body 20. The lining cover is arranged below the face cover and is connected to the face cover. For example, the lining cover can be connected to the face cover by fasteners or buckles, and the face cover and the lining cover constitute an upper cover assembly. The upper cover assembly is mainly used for centrally installing various functional components of the cover body 20, such as sensors, etc., for sensing and controlling the working state of the cooking appliance. The detachable cover is located at the innermost side of the cover body 20 and is arranged below the lining cover. The detachable cover is detachably connected to the lining cover, for example, by buckles, so as to facilitate cleaning and replacement. The detachable cover is used to face the cooking space, that is, when the cover body 20 is in the covering position, the detachable cover is located directly above the cooking space.

[0108] 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 means, 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 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.

[0109] Referring toFigures 1 to 6 、 Figures 16 to 19 The shell assembly includes a shell body 100 and a decorative band 200. The shell assembly can be made of different materials to meet different needs. 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, making the overall quality of the shell assembly lighter. The decorative band 200 gives the cooking utensil a more upscale, delicate appearance while effectively resisting deformation and damage, which can increase the overall solidity and durability. The shell body 100 and the decorative band 200 can be fixed by buckling. The combination of plastic and metal not only improves the appearance of the product, but also improves the durability of the product. The plastic and metal materials are different, and when they are joined together, the boundary between the materials is obvious, resulting in a lack of smoothness in the overall appearance.

[0110] Referring to Figures 1 to 6 、 Figures 10 to 14 、 Figures 16 to 17 As shown, the shell body 100 includes a first side and a second side disposed opposite each other along the thickness direction thereof, and a mounting hole 101 penetrating the first side and the second side. Among them, 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.

[0111] Referring to Figures 1 to 9 The decorative band 200 includes a body portion 210 and a plug-in portion 220 connected to each other. Among them, the body portion 210 covers at least part of the first side. The plug-in portion is at least partially located on the second side. The plug-in portion is at least partially located in the mounting hole. Through the shell assembly provided by the present scheme, the plug-in portion 220 of the decorative band 200 can be directly plugged into the mounting hole 101. Optionally, the plug-in portion 220 is directly clamped with the shell body 100, without the need for subsequent fastening process. The present scheme reduces the manufacturing cost, installation cost, improves the assembly efficiency, and reduces the maintenance cost caused by the loosening or damage of the fastener. By providing the plug-in portion 220, the firm connection between the decorative band 200 and the shell body 100 is ensured, and the stability of the overall structure of the shell assembly is enhanced.

[0112] In the present scheme, the body portion 210 includes an arc-shaped transition section 213 connected to the plug-in portion 220. Through the provision of the arc-shaped transition section 213, a natural visual transition is formed on the outer surface of the shell, avoiding the abrupt feeling caused by the hard joint, improving the appearance level, grade and delicate feeling of the product.

[0113] Referring to Figure 3Optionally, the arc-shaped transition section 213 comprises a first arc-shaped transition section 2131 and a second arc-shaped transition section 2132. The second arc-shaped transition section 2132 is closer to the plug-in part 220 than the first arc-shaped transition section 2131. The radius r1 of the first arc-shaped transition section 2131 is greater than the radius r2 of the second arc-shaped transition section 2132. The first arc-shaped transition section 2131 and the second arc-shaped transition section 2132 form a gradual visual effect, making the transition from the body part 210 to the plug-in part 220 more natural and soft, avoiding the jarring feeling of hard connection, thereby improving the level of appearance. The larger radius of the first arc-shaped transition section 2131 guides the visual flow, bringing a sense of "expanding outward". The second arc-shaped transition section 2132 near the plug-in part 220 adopts a smaller radius, bringing a more delicate and convergent transition effect to the entire outer surface. The arc-shaped transition section 213 as a whole forms a soft and gradual transition.

[0114] With reference to Figure 3 The dimension d1 of the arc-shaped transition section 213 in the height direction DH of the shell body 100 is 4-6 mm. Optionally, d1 can be but is not limited to 4 mm, 5 mm, 6 mm.

[0115] The outside radius r1 of the first arc-shaped transition section 2131 is 25-30 mm. Optionally, r1 can be but is not limited to 25 mm, 26 mm, 26.5, 28 mm, 30 mm.

[0116] The outside radius r2 of the second arc-shaped transition section 2132 is 0.2-1 mm. Optionally, r2 can be but is not limited to 0.2 mm, 0.5 mm, 0.6 mm, 0.8 mm, 1 mm.

[0117] The body part 210 is convex to the outer surface of the first side. The decorative band 200 slightly protrudes from the outer surface of the shell body 100, making the outer surface of the shell assembly more layered. Optionally, the difference d2 between the outer surface of the decorative band 200 and the outer surface of the first side is 0.4-0.6 mm. Optionally, d2 can be but is not limited to 0.4 mm, 0.5 mm, 0.6 mm. The slight difference and convex setting allow for certain errors during manufacturing and assembly, reducing the problem of improper joints or inconsistent appearance caused by processing errors, thereby improving production efficiency and product quality.

[0118] Through the above size limitation, the shell assembly has a soft transition feeling, improving the delicate appearance of the product.

[0119] The decorative band 200 is a preformed structure. The insertion 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 where 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. Through the shell assembly provided by the present scheme, the insertion portion 220 of the decorative band 200 can be directly inserted 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 required.

[0120] The shell body 100 further includes 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 be connected with the base 400. The two groups of insertion portions 220 are spaced apart in the up-down direction, and the two groups of insertion portions 220 are clamped in the mounting hole 101 and the first edge 102 respectively. Through the clamping action of the two groups of insertion portions 220, the connection stability between the decorative band 200 and the shell body 100 can be further enhanced, and the situation of loosening or falling off during use can be prevented.

[0121] Optionally, the extension portions 221 of the two groups of insertion portions 220 extend towards directions away from each other. The clamping portion 222 close to the base 400 extends away from the mounting hole 101, that is, extends towards the base 400, and the clamping portion 222 can be clamped to the inner surface of the base 400. Therefore, the clamping portion 222 can better contact the base 400 after installation, forming a more stable support.

[0122] With reference to Figures 5-6 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 portion 220 is clamped in the second hole wall 1012. During assembly, the insertion portion 220 is first inserted into the mounting hole 101, at this time the extension portion 221 is close to the first hole wall 1011, and after the clamping portion 222 passes through the mounting hole 101, the extension portion 221 can move towards the second hole wall 1012. Then, through appropriate adjustment and positioning, the clamping portion 222 of the insertion portion 220 is tightly clamped on the second hole wall 1012. Optionally, in the state where the clamping portion 222 of the insertion portion 220 is tightly clamped on the second hole wall 1012, the insertion portion 220 of the other group is clamped on the first edge 102.

[0123] With reference to Figures 10-14Optionally, the first edge 102 is formed with a notch 103, and the insertion portion 220 is located at the notch 103. The notch 103 provides necessary insertion space for the insertion portion 220. The side wall of the notch 103 can also form a better fixed fitting structure with the base 400.

[0124] The body portion 210 further 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.

[0125] On the basis of the above embodiment, 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 in 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 in the up-down direction.

[0126] On the basis of the above embodiment, 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 in the up-down direction.

[0127] It can be understood that the insertion portion 220 extends from the first side to the second side at the first edge 102 and the stepped portion 120, and the insertion portion 220 is also adapted to cooperate with the first edge 102 and the stepped portion 120 to constitute the limiting of the decorative band 200 in the up-down direction.

[0128] 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 in 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 is superposed with 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 is lapped 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.

[0129] Referring to Figure 12The wall thickness d3 at the first step surface 121 is greater than or equal to 1.5 mm. The wall thickness d4 at the second step surface 122 is greater than or equal to 0.6 mm. Reasonable wall thickness settings ensure the stability of the structure of the shell body 100, and the structure connected with the decorative band 200 is set to reasonably transition and cooperate between the shell body 100 and the decorative band 200, so as to ensure the overall aesthetics and coordination. d3 can be, but is not limited to, 1.5 mm, 2 mm, 3 mm, 5 mm. d4 can be, but is not limited to, 0.6 mm, 1 mm, 2 mm, 3 mm.

[0130] In some embodiments of the present application, the stepped portion 120 further comprises a third step surface 123, and the third step surface 123 and the decorative band 200 jointly form an outer surface of the shell assembly.

[0131] As described above, the decorative band 200 is clamped in the mounting hole 101 and the first edge 102. Optionally, the third step surface 123 is located on the side of the mounting hole 101 away from the first edge 102, so that the first step surface 121 can jointly form the outer surface of the shell assembly with the decorative band 200.

[0132] The wall thickness d5 at the third step surface 123 is greater than or equal to 2.5 mm. The third step surface 123 and the decorative band 200 jointly form an outer surface of the shell assembly, which needs to have sufficient strength and rigidity to support the overall structure and withstand possible external forces. d5 can be, but is not limited to, 2.5 mm, 3 mm, 4 mm, 5 mm. The wall thickness at the third step surface 123 is greater than or equal to 2.5 mm to ensure that it can withstand pressure and impact from the outside while maintaining the stability and durability of the overall structure.

[0133] It can be understood that the difference d2 between the outer surface of the decorative band 200 and the outer surface of the first side is the difference between the outer surface of the decorative band 200 and the outer surface of the third step surface 123.

[0134] In this scheme, the decorative band 200 further comprises 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 can be provided at the bending portion to facilitate the bending of the bendable portion 230.

[0135] On the basis of the above-mentioned embodiments, the bendable part 230 is clamped at the first edge 102. Alternatively, after the decorative band 200 is assembled to the shell body 100, the bendable part 230 is bent towards the side away from the base 400. Thus, it is ensured that 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 part between the decorative band 200 and the shell body 100, so that the installation and disassembly process of the base 400 is more convenient.

[0136] On the basis of the above-mentioned embodiments, the bendable part 230 is clamped at the first edge 102. Alternatively, after the decorative band 200 is assembled to the shell body 100, the bendable part 230 is bent towards the side away from the base 400. Thus, it is ensured that 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 part between the decorative band 200 and the shell body 100, so that the installation and disassembly process of the base 400 is more convenient.

[0137] On the basis of the above-mentioned embodiments, the bendable part 230 is clamped at the first edge 102. Alternatively, after the decorative band 200 is assembled to the shell body 100, the bendable part 230 is bent towards the side away from the base 400. Thus, it is ensured that 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 part between the decorative band 200 and the shell body 100, so that the installation and disassembly process of the base 400 is more convenient.

[0138] Alternatively, the bendable part 230 and the clamping part 222 are arranged in a circumferential direction. By arranging in a circumferential direction, the connection between the decorative band 200 and the shell body 100 is strengthened.

[0139] Alternatively, the bendable part 230 is arranged on the front side, the back side, the left side and the right side of the pot body 10. By arranging the bendable part 230 on the four sides of the pot body 10, it is ensured that the decorative band 200 can be tightly combined with the shell body in each direction, avoiding misalignment or looseness.

[0140] Alternatively, the number of bendable parts 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 at the combined part between the decorative band 200 and the shell body 100.

[0141] Optionally, the number of the insertion portions 220 arranged on the edge of the decorative band 200 close to the mounting hole 101 is large, which facilitates assembly. The insertion portion 220 is clamped to the second hole wall 1012 of the mounting hole 101. Understandably, the insertion portion 220 can also be arranged on the edge of the decorative band 200 close to the mounting hole 101, and during assembly, the insertion portion 220 only needs to be inserted into the mounting hole 101, without subsequent bending work.

[0142] 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. Since the distance of the mounting hole 101 is large, the insertion portion 220 can relatively easily enter 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 extension portion 221, the mounting hole 101 cannot well limit the decorative band 200 during assembly.

[0143] Optionally, the mounting hole 101 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 toward and spaced from the second hole wall 1012. At least part of the extension portion 221 is located between the free end and the second hole wall 1012. The distance 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 and the second hole wall 1012 can effectively limit the clamping portion 222 to prevent it from shifting or shaking during use. The material of the elastic clamping arm 110 has certain elasticity and toughness to ensure that it can maintain stable elastic force and shape during use. During assembly of the decorative band 200, when the clamping portion 222 enters the mounting hole 101, it can abut against the elastic clamping arm 110, and the clamping portion 222 extrudes the elastic clamping arm 110 to deform. After passing through the mounting hole 101, the insertion portion 220 moves toward the second hole wall 1012, and the extension portion 221 can act on the elastic clamping arm 110. After the external force is removed, the elastic clamping arm 110 returns to the original state, and the extension portion 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 buckled under the action of the elastic clamping arm 110, without the need for additional fixing operation, thereby improving the assembly efficiency.

[0144] The elastic clamping arm 110 provides guidance and positioning for the insertion of the insertion part 220, and helps to limit the movement range of the insertion part 220, ensuring the accuracy of assembly. Optionally, when the insertion part 220 is fully inserted, the elastic clamping arm 110 abuts against the insertion part 220 or has a small gap with the insertion part 220, thereby limiting the insertion part 220 in the up-down direction, thereby forming an additional fixed barrier to prevent the insertion part 220 from loosening or falling off during installation and use. The elastic clamping arm 110 realizes the support and fixation of the decorative band 200, so that the decorative band 200 is tightly engaged with the shell body 100.

[0145] In the present scheme, the elastic clamping arm 110 is spaced apart from the body part 210 in the thickness direction of the shell body 100. Spacing the elastic clamping arm 110 and the body part 210 apart realizes the clearance arrangement of the elastic clamping arm 110 and the insertion part 220. By clearance arrangement, the insertion part 220 has more space for fine adjustment when inserted into the mounting hole 101, making the assembly process smoother and reducing the assembly difficulty. The clearance arrangement also helps to maintain the neatness and beauty of the appearance of the cooking utensil. In the state that the decorative band 200 is assembled to the shell body 100, the relative position of the decorative band 200 and the shell body 100 is limited by the insertion part 220, and no disharmony in appearance is caused by manufacturing tolerances or material expansion of the elastic clamping arm 110.

[0146] Referring to Figure 3 Optionally, in the thickness direction of the shell body 100, the distance d6 between the elastic clamping arm 110 and the body part 210 is 0.5-1.5mm. This distance range ensures that the insertion part 220 has enough space for fine adjustment in the mounting hole 101, making the assembly process more accurate. At the same time, the guidance and positioning effect of the elastic clamping arm 110 is fully exerted, which helps to realize the accurate assembly between the shell body 100 and the decorative band 200. d6 can be but not limited to 0.5mm, 0.8mm, 1mm, 1.5mm.

[0147] In some embodiments of the present application, the free end 112 gradually decreases in thickness towards the direction away from the fixed end 111. While achieving guidance installation, the thinning arrangement makes the elastic clamping arm 110 more deformable. Compared with the traditional uniform thickness design, the thinning arrangement can reduce stress concentration and reduce the risk of fatigue and damage of the elastic clamping arm 110 due to long-term stress.

[0148] In still some embodiments of the utility model, the free end 112 extends towards the direction away from the body part 210. The free end 112 can further guide the installation of the plug-in part 220, so that the assembly process of the elastic clamping arm 110 is more smooth and fast, and the plug-in part 220 can be more easily inserted into the mounting hole 101 and be effectively fixed by the elastic clamping arm 110.

[0149] Based on the foregoing, the free end 112 gradually decreases in thickness towards the direction away from the fixed end 111 while extending towards the direction away from the body part 210. The free end 112 of the elastic clamping arm 110 forms a gradually tapered or inclined shape. The shape of the free end 112 of the elastic clamping arm 110 can be linear, gradual or have a certain curved profile to ensure smooth guidance and fixation when the plug-in part 220 is inserted. Through the scheme, not only the assembly accuracy and stability can be improved, but also the elastic recovery and fixing effect can be enhanced.

[0150] In some embodiments of the utility model, the shell assembly further comprises a fixing piece 300, and the end of the decorative band 200 is connected to the fixing piece 300 to form a closed ring. Referring to Figure 15 , 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 requirement 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.

[0151] 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, and the overall aesthetic appearance of the decorative band 200 is not damaged.

[0152] The shell main body 100 is provided with a mounting groove 104 adapted to accommodate the fixing piece 300. The fixing piece 300 is hidden inside the decorative band 200 and located in the mounting groove 104 of the shell main body 100, so it does not occupy additional external space. Optionally, the mounting groove 104 penetrates from the first side to the second side 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 the fixed installation of the decorative band 200 and the fixing piece 300.

[0153] 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.

[0154] According to the above scheme, the decorative band 200 can be stably installed to the shell body 100. In the circumferential direction of the pot body 10, the shell body 100 and the decorative band 200 partially form a double-layer shell structure. In the double-layer shell structure, the shell 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.

[0155] A plurality of mounting holes 101 are circumferentially spaced apart on the shell body 100. A plurality of insertion portions 220 are circumferentially spaced apart on the decorative band 200. By circumferentially spacing 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 installation of the insertion portion 220 and the mounting hole 101 is required during installation, so that the assembly process is simple and efficient.

[0156] According to the above scheme, the decorative band 200 can be stably installed to the shell body 100. In the circumferential direction of the pot body 10, the shell body 100 and the decorative band 200 partially form a double-layer shell structure. In the double-layer shell structure, the shell 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.
