Description

Technical Field

[0001] This utility model relates to the field of small household appliance technology, and more specifically, to a pot body assembly and a cooking appliance having the same. Background Technology

[0002] In related technologies, for cooking appliances that use IH heating technology and spherical pots, the IH heating plate needs to be separated from the spherical pot by a certain distance to avoid deformation of the IH heating plate due to the heat of the spherical pot. Therefore, a high-temperature resistant support needs to be set between the IH heating plate and the spherical pot, and the pressure after being pressed up in the spherical pot is transferred to the IH heating plate through the support, and then transferred to the support structure on the heat preservation cover through the IH heating plate.

[0003] Because the contact surface between the spherical pot and the support is an arc-shaped surface, the force exerted by the spherical pot on the support is an oblique force. The lateral component of this oblique force acting on the support structure of the insulation cover will make the support structure prone to outward deformation relative to the main body of the insulation cover. Utility Model Content

[0004] The main objective of this invention is to provide a pot body assembly and a cooking appliance having the same, in order to solve the problem that the support structure in related technologies is prone to outward deformation.

[0005] To achieve the above objectives, according to one aspect of the present invention, a pot body assembly is provided, comprising: a heat-insulating cover, including a main body and a supporting structure, the main body being a cylindrical structure, and the supporting structure being connected to the lower end of the main body; a pot body disposed within the heat-insulating cover, the pot body having an arc-shaped supporting section; and a supporting member disposed at the supporting structure and supporting both the arc-shaped supporting section and the supporting structure, the pot body protruding downward beyond the supporting member, wherein the supporting member has a supporting surface in contact with the arc-shaped supporting section, and the tangent at any position of the supporting surface has a tangent angle α with the horizontal direction, the tangent angle α satisfying: 30°≤α≤70°.

[0006] Using the technical solution of this utility model, the pot body is used to hold the food to be cooked, the heat preservation cover is used to bear pressure during the cooking process, and the support member is set between the support structure of the heat preservation cover and the arc-shaped support section of the pot body, and can transfer the weight of the pot body and the pressure during the pressing process to the support structure. That is, the weight of the pot body and the pressure during the pressing process are transferred to the support structure with high structural strength. Specifically, the force transferred to the support structure includes a lateral force extending in the horizontal direction and a vertical force extending in the vertical direction. The vertical force mainly depends on the weight of the pot body and the pressure after pressing into the pot body. When the pressure inside the pot body is constant, as the tangent angle α increases, that is, as the position of the support surface is raised, the vertical force remains unchanged, while the lateral force increases, and the resultant force of the two also increases. At the same time, the area of ​​the bottom of the pot body exposed outside the support member and the heat preservation cover also increases, thereby allowing for a heating plate with a larger coil area to improve heating efficiency. By limiting the tangent angle α to the aforementioned range, the lateral force is kept within the tolerance range of the insulation cover, preventing deformation. Simultaneously, the area of ​​the bottom of the pot exposed above the support and insulation cover is maximized to ensure heating efficiency and cooking effect. In other words, the above arrangement balances the deformation resistance of the insulation cover with the heating efficiency of the pot. Therefore, the technical solution of this embodiment effectively solves the problem of outward deformation of the support structure in related technologies.

[0007] Furthermore, the tangent angle α satisfies: 30°≤a≤45°. By controlling the tangent angle α within the above range, and while keeping the lateral force within the tolerance range of the insulation cover, the area of ​​the bottom of the pot exposed to the support and insulation cover is increased, thereby improving heating efficiency and cooking effect.

[0008] Furthermore, the pot body includes side walls and a bottom wall. On any longitudinal section passing through the vertical centerline of the pot body, the side walls protrude outwards, and the side walls have a maximum lateral dimension segment. The arc-shaped support segment is located below the maximum lateral dimension segment. There is a vertical interval D1 between the lower end of the main body and the maximum lateral dimension segment, and the vertical interval D1 satisfies: 40mm≤D1≤50mm. By keeping the vertical interval D1 within the above range, on the one hand, sufficient lateral and vertical space can be left between the main body and the arc-shaped support segment for the installation of support structures and support components without increasing the diameter of the main body; on the other hand, the overall vertical dimension of the heat insulation cover can be minimized, reducing the manufacturing cost of the heat insulation cover and the pot body assembly. At the same time, a larger area of ​​the bottom of the pot body is exposed downwards to the support structure and support components, resulting in a relatively large effective heating area at the bottom of the pot body and improving heating efficiency.

[0009] Furthermore, the support member includes a first support portion and a second support portion connected to each other. The first support portion is located above the support structure and supports it, while the second support portion is located inside the support structure and supports it. The support member can decompose the oblique force applied by the arc-shaped support segment into a lateral force acting outward in the transverse direction and a vertical force acting downward in the vertical direction. The vertical force is transmitted to the support structure via the first support portion, and the lateral force is transmitted to the support structure via the second support portion. This allows the relatively strong support structure to serve as the final load-bearing member, preventing damage to the support member.

[0010] Furthermore, the support structure includes a transverse flange connected to the lower end of the main body and extending inward, and a vertical flange connected to the inner end of the transverse flange. A first support portion cooperates with the transverse flange, and a second support portion cooperates with the vertical flange. By cooperating with the transverse flange, the aforementioned vertical force can be transmitted to the support structure; by cooperating with the vertical flange, the aforementioned transverse force can be transmitted to the support structure.

[0011] Furthermore, the upper end of the vertical flange is connected to the horizontal flange, while the lower end of the vertical flange is a free end. This arrangement avoids the vertical flange occupying the space between the horizontal flange and the arc-shaped support section, allowing the horizontal flange to be positioned as high as possible, thereby reducing the overall height of the main body and maximizing the effective heating area at the bottom of the pot.

[0012] Furthermore, the length L1 of the horizontal flange satisfies: 8mm ≤ L1 ≤ 35mm; and / or, the length L2 of the vertical flange satisfies: 4mm ≤ L2 ≤ 10mm. Keeping the length L1 within the above range ensures that the horizontal flange is as short as possible while still extending below the curved support section to support the support member, thereby improving the structural strength and deformation resistance of the horizontal flange. Keeping the length L2 within the above range also strengthens the horizontal flange while minimizing the material usage of the vertical flange, thus reducing the cost of the insulation cover.

[0013] Furthermore, the pot body assembly also includes a heating plate, which is connected to the support structure and / or support member and covers the bottom of the pot body. This arrangement allows the heating plate to completely cover the portion of the pot body exposed above the support structure and support member, thereby increasing the effective heating area on the pot body and improving heating efficiency.

[0014] Furthermore, the heating plate is an IH heating plate, comprising a plate body and a coil structure disposed below the plate body. There is an extension interval D2 between the upper edge of the projection of the coil structure onto the outer wall of the pot and the lower edge of the projection of the supporting structure onto the outer wall of the pot, wherein the extension interval D2 satisfies: 8mm ≤ D2 ≤ 12mm. Controlling the extension interval D2 within the above range ensures a certain distance between the edge of the coil structure and the supporting structure, maximizing the area of ​​the coil structure while preventing it from heating the insulation cover, thereby increasing the effective heating area on the pot body.

[0015] Furthermore, the heating plate is an IH heating plate, comprising a plate body, a connecting part, and a coil structure. The coil structure is located below the plate body, and the connecting part is located at the upper end of the plate body, below and connected to the support structure. Compared to the scheme of installing the heating plate onto the insulation cover from top to bottom, the above arrangement does not need to consider the issue of the coil structure avoiding the support structure, thus allowing the diameter of the coil structure to be set as large as possible to increase the effective heating area on the pot and improve heating efficiency.

[0016] Furthermore, the cooker assembly also includes an outer shell with a support column extending from bottom to top. The heating plate includes a plate body, a coil structure disposed below the plate body, and a support mating part disposed below the plate body and outside the coil structure. The support column and the support mating part provide a support fit. By providing an upwardly extending support column on the outer shell to connect and support the support mating part, the bottom of the heat preservation cover and the heating plate can be supported by the support column, thereby improving the overall structural stability of the cooker assembly.

[0017] Furthermore, the heating plate is an IH heating plate, comprising a plate body and a coil structure disposed below the plate body. The lateral dimension of the largest lateral segment of the pot body within a preset vertical plane is the first lateral dimension D3, and the lateral dimension of the outer edge of the coil structure within the preset vertical plane is the second lateral dimension D4. The first lateral dimension D3 and the second lateral dimension D4 satisfy the following ratio: 0.8 ≤ D4 / D3 ≤ 0.94, where the preset vertical plane is a plane passing through the vertical centerline of the pot body. By controlling the ratio between the second lateral dimension D4 and the first lateral dimension D3 within the above range, sufficient space can be provided for the arrangement of the support structure and support components without increasing the diameter of the insulation cover, while maximizing the area of ​​the coil structure, thereby improving heating efficiency.

[0018] According to another aspect of this utility model, a cooking appliance is provided, including a pot body assembly, wherein the pot body assembly is the aforementioned pot body assembly. The aforementioned pot body assembly effectively solves the problem of outward deformation of the supporting structure in related technologies, and the cooking appliance having the aforementioned pot body assembly also has the aforementioned advantages.

[0042] like Figure 1 , Figure 2 and Figure 11 As shown, this application provides a pot body assembly. An embodiment of the pot body assembly includes: a heat insulation cover 10, a pot body 20, and a support member 30. The heat insulation cover 10 includes a main body 11 and a support structure 12. The main body 11 has a cylindrical structure, and the support structure 12 is connected to the lower end of the main body 11. The pot body 20 is disposed inside the heat insulation cover 10 and has an arc-shaped support section 21. The support member 30 is disposed at the support structure 12 and supports both the arc-shaped support section 21 and the support structure 12. The pot body 20 protrudes downwards from the support member 30. The support member 30 has a support surface 31 that contacts the arc-shaped support section 21. A tangent angle α is formed between the tangent l at any position of the support surface 31 and the horizontal direction, satisfying: 30° ≤ α ≤ 70°.

[0043] Using the technical solution of this embodiment, the pot body 20 is used to hold the food to be cooked, the heat insulation cover 10 is used to bear pressure during the cooking process, and the support member 30 is arranged between the support structure 12 of the heat insulation cover 10 and the arc-shaped support section 21 of the pot body 20, and can transfer the weight of the pot body 20 and the pressure during the pressing process to the support structure 12. That is, the weight of the pot body 20 and the pressure during the pressing process are both transferred to the support structure 12 with high structural strength. Specifically, the force transmitted to the support structure 12 includes a lateral force extending in the horizontal direction and a vertical force extending in the vertical direction. The vertical force mainly depends on the weight of the pot body 20 and the pressure inside the pot body 20 after being pressed up. When the pressure inside the pot body 20 is constant, as the tangent angle α increases, that is, as the position of the support surface 31 is raised, the vertical force remains unchanged, while the lateral force becomes larger and larger, and the resultant force of the two also becomes larger and larger. At the same time, the area of ​​the bottom of the pot body 20 exposed outside the support member 30 and the heat preservation cover 10 also becomes larger and larger, so that a heating plate 40 with a larger coil area can be set to improve the heating efficiency. By limiting the tangent angle α to the aforementioned range, on the one hand, the lateral force is kept within the tolerance range of the insulation cover 10, making it less prone to deformation; on the other hand, the area of ​​the bottom of the pot body 20 exposed to the support member 30 and the insulation cover 10 is maximized to ensure heating efficiency and cooking effect. In other words, the above-mentioned arrangement balances the anti-deformation effect of the insulation cover 10 with the heating efficiency of the pot body 20. Therefore, the technical solution of this embodiment can effectively solve the problem of outward deformation of the support structure in related technologies.

[0044] Figure 11 Comparative diagrams are shown of different embodiments in which the support member 30 is supported at different height positions on the pot body 20. From top to bottom, the diagrams show three embodiments where the tangent angle α of the support surface 31 is 70°, 45°, and 30°. The vertical force, F, remains constant at all three positions. 11 =F 12 =F 13 The lateral force gradually increases with the increase of the tangent angle α, that is, F 21 >F 22 >F 23 Correspondingly, the resultant force of the vertical and horizontal forces gradually increases with the increase of the tangent angle α, that is, F 合1 >F 合2 >F 合3 Preferably, the tangent angle α can be 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, or 70°.

[0045] like Figure 8 and Figure 11As shown, the support surface 31 has a certain extension length, and the tangent angle α is different at different positions along the extension direction of the support surface 31. The aforementioned "tangent angle α satisfies: 30°≤a≤70°" means that the tangent angle α at any point on the support surface 31 satisfies the above condition. The aforementioned "arc-shaped support segment 21" refers to the outline of the wall surface of this segment of the pot body 20 intercepted by a plane passing through the vertical center line of the pot body 20, which is composed of one or more arc segments.

[0046] Preferably, the tangent angle α satisfies: 30°≤a≤45°. By controlling the tangent angle α within the above range, and while keeping the lateral force within the tolerable range of the heat insulation cover 10, the area of ​​the bottom of the pot body 20 exposed to the support member 30 and the heat insulation cover 10 is increased, which means the area of ​​the bottom of the pot body 20 that can be heated is increased, thereby improving heating efficiency and cooking effect.

[0047] In this embodiment, by supporting the support member 30 on the support structure 12 and the arc-shaped support section 21, direct contact between the two metal structures, the heat preservation cover 10 and the pot body 20, can be avoided. This reduces wear on the arc-shaped support section 21 of the pot body 20 during rotation relative to the heat preservation cover 10, and also prevents the high temperature on the pot body 20 from being directly transferred to the heat preservation cover 10. The support member 30 can be made of high-temperature resistant plastic materials such as PPS (polyphenylene sulfide) through injection molding.

[0048] like Figure 2 and Figure 3 As shown, the pot body 20 includes a side wall and a bottom wall. On any longitudinal section passing through the vertical center line of the pot body 20, the side wall protrudes outward and has a maximum lateral dimension segment 22. The arc-shaped support segment 21 is located below the maximum lateral dimension segment 22. There is a vertical interval D1 between the lower end of the main body 11 and the maximum lateral dimension segment 22. The vertical interval D1 satisfies: 40mm≤D1≤50mm. The largest lateral dimension segment 22 of the pot body 20 is located at the middle of the pot body 20. By keeping the vertical interval D1 within the aforementioned range, sufficient lateral and vertical space can be provided between the main body 11 and the arc-shaped support segment 21 for the installation of the support structure 12 and the support member 30 without increasing the diameter of the main body 11. Furthermore, the overall vertical dimension of the heat insulation cover 10 can be minimized, reducing the manufacturing cost of the heat insulation cover 10 and the pot body assembly. Simultaneously, a larger area of ​​the bottom of the pot body 20 is exposed downwards to the support structure 12 and the support member 30. Therefore, the area of ​​the coil structure 42 of the heating plate 40 can be set as large as possible, resulting in a relatively large effective heating area at the bottom of the pot body 20 and improved heating efficiency. Preferably, D1 can be 40mm, 45mm, or 50mm.

[0049] It should be noted that in this embodiment, the pot body 20 is a spherical pot, and the aforementioned maximum lateral dimension segment 22 refers to the maximum latitude circle position of the spherical pot. By having the support member 30 support the side wall of the pot body 20 located below the maximum latitude circle (i.e., the arc-shaped support segment 21), compared to the related art where the support member directly supports the bottom of the pot body, a larger heating plate 40 can be selected, thereby improving heating efficiency.

[0050] The vertical interval D1 refers to the vertical distance between the lower end of the main body 11 (specifically, the outer end of the lower surface of the transverse flange 121 in this embodiment) and the maximum transverse dimension segment 22.

[0051] In embodiments not shown in the figures, the pot body is not limited to a spherical pot. For example, the pot body may have a cylindrical section and a contracting section disposed below the cylindrical section, the cross-sectional area of ​​which gradually decreases from top to bottom. In this case, the cylindrical section forms the maximum lateral dimension section, and part of the contracting section forms an arc-shaped support section. The aforementioned "vertical interval D1 between the lower end of the main body and the maximum lateral dimension section" refers to the vertical interval between the lower end of the main body and the lower end of the cylindrical section.

[0052] like Figure 2 , Figure 3 and Figure 6 As shown, the main body 11 is provided with inwardly protruding support ribs 111, which support and cooperate with the largest lateral dimension segment 22 of the pot body 20. Specifically, there are multiple support ribs 111 arranged along the circumferential direction of the main body 11, and the lateral distance between each support rib 111 and the largest lateral dimension segment 22 is greater than or equal to 0.5 mm and less than or equal to 2 mm. The support ribs 111 can support the pot body 20, and when the pot body 20 is not placed upright inside the heat preservation cover 10, the pot body 20 can automatically return to its upright position through the combined action of the support member 30 and the support ribs 111.

[0053] like Figures 2 to 4As shown, the support member 30 includes a first support portion 32 and a second support portion 33 that are connected to each other. The first support portion 32 is located above the support structure 12 and supports and cooperates with the support structure 12. The second support portion 33 is located inside the support structure 12 and supports and cooperates with the support structure 12. The support member 30 can decompose the oblique force applied by the arc-shaped support segment 21 into a lateral force extending outward in the transverse direction and a vertical force extending downward in the vertical direction. The vertical force is transmitted to the support structure 12 via the first support part 32, and the lateral force is transmitted to the support structure 12 via the second support part 33. This allows the support structure 12, with its relatively high structural strength, to act as the final load-bearing member, thus preventing damage to the support member 30. At the same time, the arrangement of the first support part 32 and the second support part 33 ensures that the vertical force and the lateral force act on different areas of the support structure 12, i.e., the vertical force acts on the upper part of the support structure 12, and the lateral force acts on the inner part of the support structure 12. This allows the oblique force applied by the arc-shaped support segment 21 to be transmitted to the support structure 12 relatively evenly, avoiding stress concentration in the upper part of the support member 30 and the support structure 12.

[0054] like Figures 2 to 4 as well as Figure 6 As shown, the support structure 12 includes a transverse flange 121 connected to the lower end of the main body 11 and extending inward, and a vertical flange 122 connected to the inner end of the transverse flange 121. A first support part 32 supports and cooperates with the transverse flange 121, and a second support part 33 supports and cooperates with the vertical flange 122. The first support part 32, in cooperation with the transverse flange 121, enables the transmission of the aforementioned vertical force to the support structure 12; the second support part 33, in cooperation with the vertical flange 122, enables the transmission of the aforementioned transverse force to the support structure 12. Furthermore, the connection between the transverse flange 121 and the vertical flange 122 increases the overall structural strength of the support structure 12, enabling it to withstand greater forces.

[0055] like Figures 8 to 10As shown, the support member 30 also includes a support plate 34 disposed between the first support portion 32 and the second support portion 33 and supportingly cooperating with the pot body 20. Specifically, in the top-to-bottom direction, the lateral distance between the inner surface of the support plate 34 and the vertical centerline of the pot body 20 gradually decreases, so that the extension trend of the support plate 34 is the same as the extension trend of the arc-shaped support segment 21, thus better cooperating with the arc-shaped support segment 21. The first support portion 32 includes a support rib 321 connected to the upper end of the support plate 34 and extending downwards. The support rib 321 supports and cooperates with the outer end of the transverse flange 121. Since the outer end of the transverse flange 121 is located close to the main body portion 11, the outer end of the transverse flange 121 can withstand greater forces and has stronger resistance to deformation. The lower surface shape of the support rib 321 matches the upper surface shape of the transverse flange 121, making the force transmission between the support rib 321 and the transverse flange 121 more uniform. The second support part 33 includes an inner rib and an outer rib connected to the lower end of the support plate 34. The inner rib and the outer rib are spaced apart. The outer rib fits against the vertical flange 122 and supports the vertical flange 122.

[0056] like Figure 2 and Figure 4 As shown, the support member 30 also includes a downwardly extending positioning post 35, which can pass through the through hole on the transverse flange 121 and be positioned and engaged with the groove structure on the heating plate 40, so as to achieve alignment during the assembly process of the heat preservation cover 10, the support member 30 and the heating plate 40.

[0057] like Figure 9 and Figure 10 As shown, the support member 30 also includes a reinforcing rib 36 disposed between the support plate 34 and the support rib 321. The reinforcing rib 36 has a triangular cross-section in the radial direction of the pot body 20, which can improve the overall strength of the support member 30. In addition to its reinforcing function, the lower surface of the reinforcing rib 36 can also cooperate with the transverse flange 121 for support.

[0058] like Figure 8As shown, in this embodiment, multiple support surfaces 31 are spaced apart along the circumferential direction of the pot body 20. These multiple support surfaces 31 are disposed on the support plate 34 and protrude from the inner surface of the support plate 34. By providing multiple support surfaces 31 to support the arc-shaped support segment 21, multi-point support in the circumferential direction can be achieved. This ensures sufficient support area between the two, resulting in relatively low friction when the pot body 20 rotates relative to the support member 30 during the opening process, thereby reducing wear on the arc-shaped support segment 21 and the support member 30. Furthermore, the portion between two adjacent support surfaces 31 does not contact the pot body 20, leaving a certain space between the pot body 20 and the support member 30, allowing for some deformation allowance. During the opening process, the pot body 20 can rotate relative to the support member 30, making it convenient for the user to remove the pot body 20.

[0059] Specifically, such as Figure 8 As shown, in this embodiment, there are 6 support surfaces 31, and the 6 support surfaces 31 are equally spaced on the support plate 34 along the circumferential direction of the pot body 20.

[0060] Specifically, in the circumferential direction of the support member 30, the sum of the central arc angles of the plurality of support surfaces 31 is greater than or equal to 60° and less than or equal to 90°. By controlling the sum of the central arc angles of the plurality of support surfaces 31 within the above-mentioned range, both the supporting effect on the pot body 20 and the friction of the pot body 20 during rotation relative to the support member 30 can be balanced. Preferably, the sum of the central arc angles of the plurality of support surfaces 31 can be 60°, 70°, 80° or 90°.

[0061] In a preferred embodiment, the support member 30 includes six support surfaces 31, each with a central arc angle of 12.5°, and the sum of the central arc angles of the six support surfaces 31 is 75°. Of course, for different pot shapes, the number of support surfaces is not limited to six; it can also be four or five, in which case the central arc angle of each support surface needs to be adjusted accordingly.

[0062] Specifically, the sum of the surface areas of the multiple support surfaces 31 is greater than or equal to 600 mm². 2 And less than or equal to 1800mm 2 By setting the sum of the surface areas of the multiple support surfaces 31 within the aforementioned range, both effective support for the pot body 20 and minimal friction during the rotation of the pot body 20 relative to the support member 30 can be achieved. Preferably, the sum of the surface areas of the multiple support surfaces 31 can be 600 mm². 2 700mm 2 800mm 2 900mm 2 1200mm 2 1500mm 2 Or 1800mm2 .

[0063] In a preferred embodiment, the support member 30 includes six support surfaces 31, each support surface 31 having a surface area of ​​136 mm². 2 The sum of the surface areas of the six support surfaces 31 is 816 mm². 2 .

[0064] like Figure 6 As shown, in order to further increase the structural strength of the support structure 12, a plurality of first reinforcing protrusions 1211 are provided on the transverse flange 121, and the first reinforcing protrusions 1211 are provided upward relative to the main body of the transverse flange 121; a second reinforcing protrusion 13 is provided between the transverse flange 121 and the main body 11, and the second reinforcing protrusion 13 is provided protruding towards the inner side of the heat insulation cover 10.

[0065] like Figures 8 to 10 As shown, in this embodiment, the support member 30 is a ring structure. Specifically, the first support portion 32, the second support portion 33, and the support plate 34 are all ring structures. This arrangement allows the support member 30 to shield the support structure 12, making the internal structure of the insulation cover 10 more aesthetically pleasing when the user removes the pot body 20 from the insulation cover 10. The support member 30 is injection molded and consists of a plate-like structure and a rib-like structure, facilitating its processing and molding while ensuring the precision of each functional surface (e.g., the bottom surface of the support rib 321, the support surface 31, and the outer surface of the outer rib of the second support portion 33).

[0066] In an embodiment not shown in the figure, the support member may consist of multiple support blocks, which are spaced apart along the circumferential direction of the pot body. Each support block includes a first support part, a second support part, a support plate, and a reinforcing rib.

[0067] like Figures 2 to 4 as well as Figure 6 As shown, the upper end of the vertical flange 122 is connected to the horizontal flange 121, and the lower end of the vertical flange 122 is a free end. That is, the vertical flange 122 extends from top to bottom. This arrangement avoids the vertical flange 122 occupying the space between the horizontal flange 121 and the arc-shaped support section 21. In this way, while leaving enough space for the support member 30, the horizontal flange 121 can be set as high as possible, so as to reduce the overall height of the main body 11 and make the effective heating area at the bottom of the pot body 20 as large as possible.

[0068] like Figure 2 and Figure 3As shown, the length L1 of the transverse flange 121 satisfies: 8mm ≤ L1 ≤ 35mm. By keeping the length L1 within this range, the transverse flange 121 is designed to be as short as possible while still extending below the arc-shaped support section 21 to support the support member 30, thereby improving the structural strength and deformation resistance of the transverse flange 121. Preferably, the length L1 can be 8mm, 12mm, 16mm, 20mm, 23mm, 27mm, 31mm, or 35mm.

[0069] like Figure 2 and Figure 3 As shown, the length L2 of the vertical flange 122 satisfies: 4mm ≤ L2 ≤ 10mm. Keeping the length L2 within this range ensures that while reinforcing the horizontal flange 121, the material usage of the vertical flange 122 is minimized, thereby reducing the cost of the insulation cover 10. Preferably, the length L2 can be 4mm, 6mm, 8mm, or 10mm.

[0070] It should be noted that "length L1" refers to the length of the transverse flange 121 in its extending direction, and "length L2" refers to the length of the vertical flange 122 in its extending direction. Specifically, as... Figure 3 As shown, in this embodiment, the horizontal flange 121 extends in the horizontal direction and the vertical flange 122 extends in the vertical direction. The length L1 refers to the length of the lower end of the outer surface of the main body 11 and the upper end of the inner surface of the vertical flange 122 in the radial direction of the heat insulation cover 10. The length L2 refers to the length of the upper end of the upper surface of the horizontal flange 121 to the lower end of the vertical flange 122 in the vertical direction.

[0071] like Figures 2 to 5 As shown, the pot body assembly also includes a heating plate 40, which is connected to the support structure 12 and / or the support member 30 and covers the bottom of the pot body 20. The heating plate 40 can heat the bottom of the pot body 20 to heat the food inside the pot body 20. Specifically, the heating plate 40 is connected to the support structure 12 and / or the support member 30 so that the heating plate 40 can completely cover the portion of the pot body 20 exposed above the support structure 12 and the support member 30, thereby increasing the effective heating area on the pot body 20 and improving heating efficiency.

[0072] like Figure 2 and Figure 4As shown, the heating plate 40 is an IH heating plate, which includes a plate body 41 and a coil structure 42 disposed below the plate body 41. There is an extension interval D2 between the upper edge of the projection of the coil structure 42 onto the outer wall of the pot body 20 and the lower edge of the projection of the support structure 12 onto the outer wall of the pot body 20, wherein the extension interval D2 satisfies: 8mm ≤ D2 ≤ 12mm. Controlling the extension interval D2 within the above range ensures a certain distance between the edge of the coil structure 42 and the support structure 12, maximizing the area of ​​the coil structure 42 while preventing it from heating the insulation cover 10, thereby increasing the effective heating area on the pot body 20. Preferably, the extension interval D2 can be 8mm, 10mm, or 12mm.

[0073] like Figures 2 to 5 as well as Figure 7 As shown, the heating plate 40 is an IH heating plate, which includes a plate body 41, a connecting part 43, and a coil structure 42. The coil structure 42 is located below the plate body 41, and the connecting part 43 is located at the upper end of the plate body 41. The connecting part 43 is located below the support structure 12 and connected to the support structure 12. The connecting part 43 is connected to the lower part of the support structure 12, so that the heating plate 40 can dock and connect with the support structure 12 from bottom to top. Compared with the solution of installing the heating plate on the heat preservation cover from top to bottom, there is no need to consider the problem of the coil structure 42 avoiding the support structure 12. This allows the diameter of the coil structure 42 to be set as large as possible, thereby increasing the effective heating area on the pot body 20 and improving the heating efficiency.

[0074] In related technologies, a cooling fan is typically installed inside the cooker assembly to cool the coil structure of the heating plate. Since the flanged structure of the insulation cover extends below the heating plate, meaning the insulation cover covers the outer perimeter of the heating plate, a significant portion of the insulation cover needs to be cut away to create an installation notch to allow the cooling fan's outlet to be aligned with the coil structure of the heating plate. However, this compromises the integrity of the insulation cover, particularly the flanged structure, leading to reduced structural strength and insufficient support. In this embodiment, by raising the lower end of the heat insulation cover 10 and connecting the heating plate 40 to the lower part of the support structure 12, the heating plate 40 is completely exposed relative to the heat insulation cover 10, and there is enough space below the heat insulation cover 10 and the heating plate 40 to install a cooling fan. The cooling fan can be directly connected to the heating plate 40, and the heat insulation cover 10 will not block the air intake of the cooling fan. Therefore, it is not necessary to set a notch on the heat insulation cover 10 for installing the heat dissipation bracket, thereby ensuring the structural integrity of the heat insulation cover 10 and improving the structural strength and support capacity of the support structure 12.

[0075] Of course, in embodiments not shown in the figure, the connecting portion may also extend above the support structure and connect to both the support structure and the support member.

[0076] like Figure 4 As shown, a water-blocking rib 431 is provided on the connecting part 43. The water-blocking rib 431 extends between the inner and outer ribs of the second support part 33. The inner rib of the second support part 33 is aligned with the upper end of the pan body 41, and the inner surface of the inner rib is flush with the upper surface of the pan body 41. This arrangement ensures that when the pot body 20 is removed from the heat preservation cover 10, the seam at the joint between the heating plate 40 and the support 30 is relatively small, resulting in a more aesthetically pleasing appearance and improving the user experience. In addition, the water-blocking rib 431 can prevent liquid from seeping in from the seam between the heating plate 40 and the support 30 (e.g., water residue left after the pot body 20 has been cleaned), thereby preventing liquid from flowing to the coil structure 42 or other electrical components inside the pot body assembly.

[0077] like Figure 7 and Figure 12 As shown, the cooker body assembly also includes a shell 50, which has a support column extending from bottom to top. The heating plate 40 includes a plate body 41, a coil structure 42 disposed below the plate body 41, and a support mating part 44 disposed below the plate body 41 and located outside the coil structure 42. The support column and the support mating part 44 provide a support mating fit. In this embodiment, since the bottom of the heat preservation cover 10 is raised and the connecting part 43 of the heating plate 40 is directly connected to the support structure 12 of the heat preservation cover 10, the position of the connecting part 43 is also relatively high. By providing an upwardly extending support column on the shell 50 to connect and support the supporting part 44, the bottom of the heat preservation cover 10 and the heating plate 40 can be supported by the support column, thereby improving the overall structural stability of the cooker body assembly.

[0078] like Figure 2As shown, the heating plate 40 is an IH heating plate, which includes a plate body 41 and a coil structure 42 disposed below the plate body 41. The lateral dimension of the maximum lateral segment 22 of the pot body 20 in a preset vertical plane is the first lateral dimension D3, and the lateral dimension of the outer edge of the coil structure 42 in the preset vertical plane is the second lateral dimension D4. The first lateral dimension D3 and the second lateral dimension D4 satisfy the following condition: 0.8 ≤ D4 / D3 ≤ 0.94, where the preset vertical plane is a plane passing through the vertical center line of the pot body 20. By controlling the ratio between the second lateral dimension D4 and the first lateral dimension D3 within the above range, sufficient space can be provided for the arrangement of the support structure 12 and the support member 30 without increasing the diameter of the heat preservation cover 10, while maximizing the area of ​​the coil structure 42, thereby improving heating efficiency. Preferably, D3 / D4 can be 0.8, 0.85, 0.9, or 0.94.

[0079] like Figure 2 As shown, the first lateral dimension D3 and the second lateral dimension D4 mentioned above both refer to the dimensions in the horizontal direction.

[0080] like Figure 2 As shown, in a preferred embodiment, the pot body 20 is a spherical pot, and the aforementioned maximum lateral dimension segment 22 refers to the maximum weft circle position of the spherical pot. The diameter of the maximum weft circle (i.e., the first lateral dimension D3) is 223 mm, and the diameter of the outer edge of the coil structure 42 (i.e., the second lateral dimension D4) is greater than or equal to 180 mm and less than or equal to 210 mm.

[0081] like Figure 12 As shown, this application also provides a cooking appliance. An embodiment of the cooking appliance of this application includes a pot body assembly, which is the pot body assembly described above. The pot body assembly described above can effectively solve the problem of outward deformation of the supporting structure in related technologies, and the cooking appliance having the pot body assembly described above also has the aforementioned advantages.

[0082] like Figure 12 As shown, the cooking appliance is a pressure cooking appliance, and the cooking appliance also includes a lid assembly 60 that is openable and closable on the pot body assembly.

Directional terms such as "front, back, up, down, left, right," "horizontal, vertical, perpendicular, horizontal," and "top, bottom" indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. These terms are used solely for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner or outer contours relative to the outline of each component itself.

[0084] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures.
