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 pressure cooking appliances with a spherical pot, the heat insulation cover generally includes a cylindrical part and a support edge disposed at the lower end of the cylindrical part and extending into the inside of the cooking appliance.

[0003] The support edge is located below the heating coil, and a support member is also provided between the spherical pot and the support edge. The support member passes through the heating coil and transmits the weight of the spherical pot and the pressure after being pressed up to the support edge. Because the pressure inside the spherical pot is very high after being pressed up, the support edge is prone to deformation under stress. 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 edge of the heat preservation cover in related technologies is prone to deformation.

[0005] To achieve the above objectives, according to one aspect of the present invention, a pot body assembly is provided, comprising: a pot body having an arc-shaped support section; a heat-insulating cover disposed on the outer periphery of the pot body, the heat-insulating cover including a cylindrical portion and a support portion disposed at the lower end of the cylindrical portion, the support portion having a first force-bearing area and a second force-bearing area; a support member disposed at the support portion and supportingly engaging with the arc-shaped support section, the support member supportingly engaging with the first force-bearing area and applying a first force to the first force-bearing area, the support member supportingly engaging with the second force-bearing area and applying a second force to the second force-bearing area, wherein the directions of the first force and the second force are arranged at an angle.

[0006] Using the technical solution of this embodiment, the pot body is used to hold food, and the heat-insulating cover is set on the outer periphery of the pot body to bear pressure after the pot body is pressed. Specifically, the heat-insulating cover includes a support part, and the pot body assembly also includes a support member disposed between the support part of the heat-insulating cover and the arc-shaped support mating section of the pot body. The lateral dimension of the arc-shaped support mating section gradually decreases from top to bottom, and the support member abuts against the arc-shaped support mating section to achieve side support for the pot body. Compared with the support edge that needs to extend to the bottom of the pot body in related technologies, the support part in this embodiment is located between the lower end of the cylindrical part and the arc-shaped support mating section, which has greater structural strength and is less prone to deformation after being subjected to the same magnitude of force. In addition, the support part has a first force-bearing area and a second force-bearing area to bear the first force and the second force at an angle, respectively, so that the first force and the second force can be transmitted to the support part relatively evenly, avoiding the situation of local stress concentration and deformation of the support part, and further reducing the probability of deformation of the support part. Therefore, the technical solution of this application can effectively solve the problem that the support edge on the heat-insulating cover is prone to deformation in related technologies.

[0007] Furthermore, the support portion includes a transverse flange, which is supported below the support member, and the first stress-bearing zone is formed on the transverse flange. By providing a transverse flange at the lower end of the cylindrical portion for support and engagement with the support member, it has the advantages of simple structure and ease of processing and manufacturing.

[0008] Furthermore, the support also includes a vertical flange connected to the inner side of the transverse flange, and the second stress zone is formed on the vertical flange. The vertical flange increases the structural strength of the transverse flange, thereby enhancing its support capacity, and also allows it to withstand the second force.

[0009] Furthermore, the support component includes a first support portion and a second support portion connected to the inner side of the first support portion. The first support portion is located above the horizontal flange and cooperates with the horizontal flange support, while the second support portion is located inside the vertical flange and cooperates with the vertical flange support. By setting the first support portion and the second support portion to cooperate with the horizontal flange and the vertical flange support respectively, the first force and the second force can be transmitted to the support portion relatively evenly, thereby making the support portion less prone to deformation after long-term use and increasing the service life of the insulation cover.

[0010] Furthermore, the first support portion includes a support plate, a first support rib, and a connecting rib. The support plate extends along a predetermined arc direction, the first support rib is connected to the outer end of the support plate and extends downward, and the first support rib cooperates with the transverse flange support. The connecting rib connects the support plate and the first support rib. The extension trend of the support plate is the same as the extension trend of the arc-shaped support cooperation section, enabling the arc-shaped support cooperation section to better transmit the pressure of the pot body to the support component. The cooperation of the first support rib with the transverse flange support can save material costs for the support component and better ensure the accuracy of the support surface of the first support rib.

[0011] Furthermore, the first support portion includes a support plate extending along a predetermined arc direction, and the second support portion is connected to the lower end of the support plate. The connection of the second support portion to the lower end of the support plate allows the force acting on the support plate to be transmitted to the second support portion and then to the vertical flange via the second support portion.

[0012] Furthermore, the first support portion includes a support plate and a plurality of second support ribs spaced apart along the circumferential direction of the pot body. The support plate extends along a predetermined arc direction, and each second support rib extends along the radial direction of the pot body. The second support ribs cooperate with the central support of the transverse flange. The extension trend of the support plate is the same as the extension trend of the arc-shaped support cooperation section, which allows the arc-shaped support cooperation section to better transmit the pressure of the pot body to the support component. The cooperation between the second support ribs and the central support of the transverse flange can prevent interference between the outer structure of the first support portion and the cylindrical part of the insulation cover, thus avoiding affecting the assembly of the insulation cover and the pot body.

[0013] Furthermore, the upper end of the vertical flange is connected to the inner end of the horizontal flange, while the lower end of the vertical flange is a free end. This reduces the space occupied between the horizontal flange and the arc-shaped support section of the pot body, allowing the vertical dimension of the insulation cover's cylindrical part to be set as small as possible, thus reducing the cost of the insulation cover.

[0014] Furthermore, the angle between the directions of the first and second forces is 90°. By making the first and second forces perpendicular to each other, it is easier to calculate the forces between the arc-shaped support segments and the support members, and thus easier to design the dimensions of the transverse and vertical flanges based on the magnitude of the forces.

[0015] Furthermore, the pot body assembly also includes a heating plate, which is connected to and covers the bottom of the pot body with the support and / or support member. The heating plate covering the bottom of the pot body ensures sufficient heating area for optimal heating; additionally, it allows the support member and heating plate to conceal the internal structure of the pot body assembly when the pot is removed, maintaining the aesthetic appearance of the pot body assembly after removal and thus enhancing the user experience.

[0016] Furthermore, the heating plate is an IH heating plate, which includes a plate body, a coil structure located below the plate body, and a connecting flange connected to the top of the plate body. The connecting flange is located below and connected to the support. This design avoids the heating plate occupying the space between the support and the arc-shaped support section of the pot body. On the one hand, this allows for a smaller overall height of the insulation cover, and on the other hand, it reduces the cost of the support components. In addition, the radial dimension of the coil structure can be set relatively large, allowing more area of ​​the bottom of the pot body to be heated by the coil structure, ensuring heating effect and preventing the bottom of the pot body from being scorched due to only a small area being heated.

[0017] Furthermore, the heating plate includes a plate body and a coil structure disposed below the plate body. The outer edge of the coil structure has a first distance D1 between it and the vertical centerline of the pot body, and the outer wall of the pot body at its maximum lateral dimension has a second distance D2 between it and the vertical centerline of the pot body. The first distance D1 and the second distance D2 satisfy the following condition: 0.8 ≤ D1 / D2 ≤ 0.94. By keeping D1 / D2 within the aforementioned range, on the one hand, the effective heating area of ​​the coil structure is relatively large, resulting in a larger heating area at the bottom of the pot body and ensuring heating effect; on the other hand, it also allows for a relatively small vertical dimension of the insulation cover, saving on the cost of the insulation cover, and simultaneously making the overall vertical dimension of the pot body assembly relatively small.

[0018] Furthermore, the support component is provided with multiple support protrusions at intervals, and each support protrusion is provided with a support surface that matches the arc-shaped support mating section. By providing multiple support protrusions to support and mate with the arc-shaped support mating section, it is possible to ensure that there is a sufficiently large support area between the two, while on the other hand, it is possible to control the friction between the two within a certain range, so as to reduce the wear of the pot body relative to the support component when it rotates during the opening and closing process.

[0019] Furthermore, in the circumferential direction of the cook body assembly, the sum of the central arc angles of the multiple supporting protrusions is greater than or equal to 60° and less than or equal to 90°; and / or, the sum of the surface areas of the supporting surfaces of the multiple supporting protrusions is greater than or equal to 600 mm². 2 And less than or equal to 1800mm 2 The above configuration balances the support effect on the curved support section with the reduction of wear on the pot body.

[0020] 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 easy deformation of the support edge on the heat preservation cover in related technologies, and the cooking appliance having the aforementioned pot body assembly also has the aforementioned advantages.

[0048] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, this application provides a pot body assembly. An embodiment of the pot body assembly includes a pot body 10, a heat insulation cover 20, and a support member 30. The pot body 10 has an arc-shaped support section 11. The heat insulation cover 20 is disposed on the outer periphery of the pot body 10 and includes a cylindrical portion 21 and a support portion 22 disposed at the lower end of the cylindrical portion 21. The support portion 22 has a first force-bearing area 201 and a second force-bearing area 202. The support member 30 is disposed at the support portion 22 and supports and cooperates with the arc-shaped support section 11. The support member 30 supports and cooperates with the first force-bearing area 201 and applies a first force F1 to the first force-bearing area 201. The support member 30 supports and cooperates with the second force-bearing area 202 and applies a second force F2 to the second force-bearing area 202. The directions of the first force F1 and the second force F2 are arranged at an angle.

[0049] Using the technical solution of this embodiment, the pot body 10 is used to hold food, and the heat preservation cover 20 is disposed on the outer periphery of the pot body 10 and can bear the pressure after the pot body 10 is pressed. Specifically, the heat preservation cover 20 includes a support part 22, and the pot body assembly also includes a support member 30 disposed between the support part 22 of the heat preservation cover 20 and the arc-shaped support mating section 11 of the pot body 10. The lateral dimension of the arc-shaped support mating section 11 gradually decreases from top to bottom, and the support member 30 abuts against the arc-shaped support mating section 11 to achieve side support for the pot body 10. Compared with the support edge in the related art that needs to extend to the bottom of the pot body, the support part 22 in this embodiment is located between the lower end of the cylindrical part 21 and the arc-shaped support mating section 11, which has greater structural strength and is less prone to deformation after being subjected to the same amount of force. Furthermore, the support portion 22 has a first stress-bearing area 201 and a second stress-bearing area 202 to respectively withstand the first force F1 and the second force F2 at an angle, so that the first force F1 and the second force F2 can be transmitted to the support portion 22 relatively evenly, avoiding local stress concentration and deformation of the support portion 22, and further reducing the probability of deformation of the support portion 22. Therefore, the technical solution of this embodiment can effectively solve the problem of easy deformation of the support edge on the heat insulation cover in related technologies.

[0050] For example, in Figure 1 When the pot body 10 shown is selected as a spherical vessel, the arc-shaped support fitting section 11 is below the maximum lateral dimension of the pot body 10 and located on the side of the pot body 10. It should be noted that the above-mentioned "arc-shaped support fitting section 11" refers to the section of the pot wall structure on the pot body 10 whose cross-section is formed by a vertical plane passing through the vertical center line L of the pot body 10 and consists of one or more arc segments.

[0051] Furthermore, since the support member 30 directly supports and engages with the arc-shaped support section 11 of the pot body 10, and the support member 30 can apply a first force F1 and a second force F2 set at an angle to the support portion 22 of the heat insulation cover 20, the support portion 22 of the heat insulation cover 20 is also located close to the arc-shaped support section 11. Compared with the solution in the related technology that directly sets the support edge extending to the bottom of the heating coil, the height dimension of the heat insulation cover 20 is reduced, thereby reducing the overall height dimension of the pot body assembly and lowering the product cost.

[0052] like Figures 2 to 4As shown, the cylindrical part 21 is provided with a supporting rib 211 at the position corresponding to the maximum lateral dimension of the pot body 10. The supporting rib 211 protrudes towards the pot body 10. When the pot body 10 is not level, the pot body 10 can automatically level itself under the combined action of the supporting rib 211 and the support member 30. The distance between the inner side of the supporting rib 211 and the outer side of the position of the maximum lateral dimension of the pot body 10 is greater than or equal to 0.5 mm and less than or equal to 2 mm. By setting the distance between the two within the above range, the leveling effect of the pot body 10 can be achieved on the one hand, and the supporting rib 211 will not obstruct the removal and placement of the pot body 10 on the other hand.

[0053] Specifically, in this embodiment, the pot body 10 is a spherical pot, and the "position of the maximum lateral dimension of the pot body 10" mentioned above refers to the maximum lateral circle position of the spherical pot.

[0054] like Figure 3 and Figure 5 As shown, the support portion 22 includes a transverse flange 221, which is supported below the support member 30. A first stress-bearing area 201 is formed on the transverse flange 221. By providing a transverse flange 221 at the lower end of the cylindrical portion 21 for support and cooperation with the support member 30, it has the advantages of simple structure and ease of processing and manufacturing. The first stress-bearing area 201 is formed on the upper surface of the transverse flange 221.

[0055] like Figure 3 As shown, the transverse flange 221 is provided with multiple protrusions 2211. The protrusions 2211 can increase the structural strength of the transverse flange 221, thereby improving its support capacity. In order to further enhance the structural strength of the transverse flange 221, a reinforcing rib 23 protruding towards the inside of the insulation cover 20 is also provided at the connection position between the cylinder part 21 and the transverse flange 221.

[0056] like Figure 3 and Figure 5 As shown, the support portion 22 also includes a vertical flange 222 connected to the inner side of the transverse flange 221, and a second stress-bearing area 202 is formed on the vertical flange 222. The vertical flange 222 increases the structural strength of the transverse flange 221, thereby improving its support capacity, and also withstands the second force F2. The second stress-bearing area 202 is located on the inner surface of the vertical flange 222.

[0057] Specifically, Figure 5 The thickened position on the upper surface of the transverse flange 221 and the thickened position on the inner surface of the vertical flange 222 indicate the range of the first stress zone 201 and the second stress zone 202.

[0058] like Figures 4 to 6As shown, the support member 30 includes a first support portion 31 and a second support portion 32 connected to the inner side of the first support portion 31. The first support portion 31 is located above the horizontal flange 221 and supports and cooperates with the horizontal flange 221. The second support portion 32 is located inside the vertical flange 222 and supports and cooperates with the vertical flange 222. By setting the first support portion 31 and the second support portion 32 to support and cooperate with the horizontal flange 221 and the vertical flange 222 respectively, the first force F1 can be relatively evenly transmitted to the support portion 22 through the cooperation of the first support portion 31 and the first force-bearing area 201, and the second force F2 can be relatively evenly transmitted to the support portion 22 through the cooperation of the second support portion 32 and the second force-bearing area 202. This makes the support portion 22 less prone to deformation after long-term use, increasing the service life of the insulation cover 20.

[0059] like Figures 5 to 8 As shown, the first support part 31 includes a support plate 311, a first support rib 312 and a connecting rib 313. The support plate 311 extends along a preset arc direction. The first support rib 312 is connected to the outer end of the support plate 311 and extends downward. The first support rib 312 is supported and cooperates with the transverse flange 221. The connecting rib 313 is connected between the support plate 311 and the first support rib 312. The second support part 32 is connected to the lower end of the support plate 311. The support plate 311 extends along a predetermined arc, ensuring that its extension trend aligns with that of the arc-shaped support section 11. This allows the arc-shaped support section 11 to better transfer the pressure from the pot body 10 to the support member 30. The first support rib 312 supports and cooperates with the transverse flange 221, saving material costs for the support member 30 and ensuring the accuracy of the support surface of the first support rib 312. This allows the first force F1 to be transmitted relatively evenly to the transverse flange 221, preventing excessive stress in localized areas. The connecting rib 313 connects the support plate 311 and the first support rib 312, increasing the overall strength of the first support part 31. Furthermore, the second support part 32 is connected to the lower end of the support plate 311 and fits against the vertical flange 222. When the pot body 10 is under pressure, the force acting on the support plate 311 can also be transmitted to the second support part 32 and then to the vertical flange 222.

[0060] It should be noted that the "preset arc direction" mentioned above can be the extension direction of a single arc or the extension direction of a line segment formed by combining multiple arcs, as long as it can achieve surface contact between the support plate 311 and the arc-shaped support mating section 11.

[0061] In this embodiment, the support member 30 is a ring structure, and the support plate 311, the first support rib 312, and the second support portion 32 are all ring-shaped plates or ring-shaped rib structures. Of course, in embodiments not shown in the figures, the support member can also be composed of multiple support blocks spaced apart along the circumferential direction, wherein each support block includes a first support portion and a second support portion.

[0062] Specifically, in this embodiment, the support member 30 is formed by injection molding. Both the first support part 31 and the second support part 32 are composed of plate-like structures or rib-like structures, which can ensure the surface accuracy of each functional surface (e.g., the inner surface of the support plate 311, the lower surface of the first support rib 312, and the outer surface of the second support part 32).

[0063] Since the transverse flange 221 is provided with a protrusion 2211, the lower surface of the first support rib 312 is adapted to the shape of the upper surface of the transverse flange 221, and a relief recess is provided on the first support rib 312 corresponding to the position of the reinforcing rib 23.

[0064] like Figures 2 to 5 As shown, the upper end of the vertical flange 222 is connected to the inner end of the horizontal flange 221, and the lower end of the vertical flange 222 is a free end. That is, the vertical flange 222 is a flange structure that extends from top to bottom. This can reduce the space occupied between the horizontal flange 221 and the arc-shaped support section 11 of the pot body 10, so that the vertical dimension of the cylindrical part 21 of the heat insulation cover 20 can be set as small as possible, thereby reducing the cost of the heat insulation cover 20.

[0065] like Figure 4 and Figure 5 As shown, the first force F1 is a downward force in the vertical direction, and the second force F2 is an outward force in the horizontal direction. The "vertical direction" mentioned above is not limited to the vertical direction itself; it can be the vertical direction or a direction that forms an angle with the vertical direction (e.g., the angle with the vertical direction is within 30°). Similarly, the "horizontal direction" mentioned above is not limited to the horizontal direction; it can be the horizontal direction or a direction that forms an angle with the horizontal direction (e.g., the angle with the horizontal direction is within 30°).

[0066] In a preferred embodiment, the angle between the directions of the first force F1 and the second force F2 is 90°. By making the first force F1 and the second force F2 perpendicular to each other, it is convenient to calculate the force between the arc-shaped support section 11 and the support member 30, and thus it is convenient to design the dimensions of the transverse flange 221 and the vertical flange 222 according to the magnitude of the force.

[0067] Preferably, the first force F1 extends in the vertical direction, and the second force F2 extends in the horizontal direction.

[0068] like Figure 2 , Figure 4 and Figure 15 As shown, the pot body assembly also includes a heating plate 40, which is connected to the support portion 22 and / or the support member 30 and covers the bottom of the pot body 10. The heating plate 40 covering the bottom of the pot body 10 ensures sufficient heating area for optimal heating; furthermore, when the pot body 10 is removed, the support member 30 and the heating plate 40 can conceal the internal structure of the pot body assembly, maintaining its aesthetic appearance after removal and thus enhancing the user experience.

[0069] like Figure 2 , Figure 4 and Figure 5 As shown, the heating plate 40 is an IH heating plate, which includes a plate body 41, a coil structure 42 disposed below the plate body 41, and a connecting flange 43 connected to the top of the plate body 41. The connecting flange 43 is located below and connected to the support part 22. The fact that the connecting flange 43 is located below and connected to the support part 22 avoids the heating plate 40 occupying the space between the support part 22 and the arc-shaped support mating section 11 of the pot body 10. On the one hand, this allows the overall height of the heat preservation cover 20 to be made smaller, and on the other hand, it also reduces the cost of the support component 30. In addition, since the connecting flange 43 is directly connected to the bottom of the support part 22, it is not necessary to consider reducing the radial dimension of the coil structure when installing the heating plate from top to bottom so that the coil structure can pass through the support part downward. Therefore, the radial dimension of the coil structure 42 can be set relatively large, so that more area of ​​the bottom of the pot body 10 is heated by the coil structure 42, ensuring the heating effect and avoiding the situation where only a small area of ​​the bottom of the pot body is heated, resulting in scorching.

[0070] like Figure 2 As shown, in this embodiment, the support member 30 is installed inside the heat insulation cover 20 from top to bottom and is fixed to the heat insulation cover 20 by the first connecting screw that passes through the transverse flange 221 and the support member 30 from bottom to top. The connecting flange 43 is provided with a relief recess to avoid the lower end of the first connecting screw. The heating plate 40 is connected to the support part 22 on the heat insulation cover 20 from bottom to top and is fixed to the heat insulation cover by the second connecting screw that passes through the connecting flange 43 and the transverse flange 221 from bottom to top. The first support rib 312 is provided with a relief recess to avoid the upper end of the second connecting screw.

[0071] like Figure 4 , Figure 5 and Figure 15As shown, the outer edge of the coil structure 42 has a first distance D1 between it and the vertical center line L of the pot body 10, and the outer wall of the pot body 10 at its maximum lateral dimension position has a second distance D2 between it and the vertical center line L of the pot body 10. The first distance D1 and the second distance D2 satisfy the condition: 0.8 ≤ D1 / D2 ≤ 0.94. Compared to the prior art method where the support member directly supports the bottom of the pot body, by using the support member 30 to abut against and support the side of the pot body 10, a larger heating plate 40 can be selected. With D1 / D2 within the aforementioned range, this results in a relatively larger effective heating area for the coil structure 42, thus providing a larger heating area at the bottom of the pot body 10, ensuring heating effect and improving heating efficiency. Furthermore, it allows for a relatively smaller vertical dimension of the insulation cover 20, saving on the cost of the insulation cover 20, and also making the overall vertical dimension of the pot body assembly relatively small. Preferably, D1 / D2 can be 0.8, 0.85, 0.9, or 0.94.

[0072] In a preferred embodiment, the pot body 10 is a spherical pot, the diameter of the maximum weft circle of the pot body 10 is 223mm, the effective diameter of the coil structure 42 (that is, the diameter of the outer edge of the coil structure 42) is greater than or equal to 180mm and less than or equal to 210mm, that is, 90mm≤D1≤105mm, D2=111.5mm.

[0073] like Figure 4 and Figure 6 As shown, the support member 30 is provided with multiple support protrusions 33 at intervals, and each support protrusion 33 is provided with a support surface 331 that is adapted to the arc-shaped support mating section 11. By providing multiple support protrusions 33 to support and mate with the arc-shaped support mating section 11, it is possible to ensure that there is a sufficiently large support area between the two, while also controlling the friction between them within a certain range, so as to reduce the wear of the pot body 10 relative to the support member 30 when it rotates during the opening process.

[0074] Specifically, such as Figure 6 and Figure 7 As shown, in this embodiment, the support member 30 has a ring structure and six support protrusions 33, which are arranged at equal intervals along the circumferential direction of the support member 30.

[0075] In the circumferential direction of the pot body assembly, the sum of the central arc angles of the multiple supporting protrusions 33 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 multiple supporting protrusions 33 within the above-mentioned range, the supporting effect on the arc-shaped supporting mating section 11 and the effect of reducing wear on the pot body 10 can be balanced. Preferably, the sum of the central arc angles of the multiple supporting protrusions 33 can be 60°, 65°, 70°, 75°, 80°, 85°, or 90°.

[0076] Preferably, the sum of the surface areas of the support surfaces 331 of the plurality of support protrusions 33 is greater than or equal to 600 mm. 2 And less than or equal to 1800mm 2 By controlling the sum of the surface areas of the support surfaces 331 of the multiple support protrusions 33 within the aforementioned range, both the support effect on the arc-shaped support mating section 11 and the effect of reducing wear on the pot body 10 can be achieved. Preferably, the sum of the surface areas of the support surfaces 331 of the multiple support protrusions 33 can be 600 mm². 2 700mm 2 800mm 2 900mm 2 1200mm 2 1500mm 2 Or 1800mm 2 .

[0077] Specifically, in a preferred embodiment, the support member 30 includes six support protrusions 33, each support protrusion 33 having a central arc angle of 12.5° and a surface area of ​​136 mm² for its support surface 331. 2 Correspondingly, the sum of the central arc angles of the six supporting protrusions 33 is 75°, and the sum of the surface areas of the supporting surfaces 331 of the six supporting protrusions 33 is 816 mm. 2 .

[0078] Figures 9 to 10 A structural diagram of another embodiment of the cook body assembly provided in this application is shown. The following mainly describes the differences between this embodiment and the previous one. Figure 1 The embodiments will be described in part, and the parts that are the same in the two embodiments will not be described again.

[0079] like Figure 9 and Figure 10 As shown, the first support portion 31 includes a support plate 311 and a plurality of second support ribs 314 spaced apart along the circumferential direction of the pot body 10. The support plate 311 extends along a predetermined arc direction, and each second support rib 314 extends along the radial direction of the pot body 10. The second support ribs 314 cooperate with the middle support of the transverse flange 221. The extension trend of the support plate 311 is the same as the extension trend of the arc-shaped support cooperation section 11, so that the arc-shaped support cooperation section 11 can better transmit the pressure of the pot body 10 to the support member 30. The cooperation between the second support ribs 314 and the middle support of the transverse flange 221 can avoid interference between the outer structure of the first support portion 31 and the cylindrical portion 21 of the heat insulation cover 20, thus avoiding affecting the assembly of the heat insulation cover 20 and the pot body 10.

[0080] like Figure 9 and Figure 10As shown, the first support part 31 also includes a connecting ring rib 315 connected to the outside of the plurality of second support ribs 314. The setting of the connecting ring rib 315 can increase the overall structural strength of the first support part 31. The lower end of the connecting ring rib 315 is spaced apart from the transverse flange 221, so that there is a certain space between the connecting ring rib 315 and the heat insulation cover 20, which facilitates the assembly of the heat insulation cover 20 and the support member 30.

[0081] Figures 11 to 13 The diagram shows a simplified structural diagram of the heat insulation cover 20 in other embodiments of the pot body assembly, as well as a force diagram of the heat insulation cover 20 and the support member 30 when they are in contact. The specific structures of the support member 30 and the support part 22 may differ in these embodiments, but the structures of other parts of the pot body assembly are the same. The following mainly describes the different parts in each embodiment, and the same content in each embodiment will not be repeated.

[0082] like Figure 11 As shown, in this embodiment, the vertical flange 222 is connected to the inner end of the horizontal flange 221 and extends upward. The first force-bearing area 201 is formed on the upper surface of the horizontal flange 221, and the second force-bearing area 202 is formed on the inner surface of the vertical flange 222. The first force F1 is downward and acts on the horizontal flange 221, and the second force F2 is outward and acts on the vertical flange 222.

[0083] like Figure 12 As shown, in this embodiment, the support portion 22 includes a vertical section connected to the lower end of the cylindrical portion 21 and extending downward, and a transverse section connected to the lower end of the vertical section and extending inward. A first force-bearing area 201 is formed on the upper surface of the transverse section, and a second force-bearing area 202 is formed on the inner surface of the vertical section. A first force F1 acts downward and on the transverse section, and a second force F2 acts outward and on the vertical section.

[0084] like Figure 13 As shown, in this embodiment, the support portion 22 includes a vertical section connected to the lower end of the cylindrical portion 21 and extending downward, a transverse flange 221 connected to the lower end of the vertical section and extending inward, and a vertical flange connected to the inner end of the transverse flange 221 and extending downward. A first force-bearing area 201 is formed on the upper surface of the transverse flange 221, and a second force-bearing area 202 includes a first sub-region formed on the inner surface of the vertical section and a second sub-region formed on the inner surface of the vertical flange 222. A first force F1 acts downward and on the transverse flange 221, and a second force acts outward and is divided into a force F21 and a force F22. The force F21 acts on the vertical flange 222, and the force F22 acts on the vertical section.

[0085] Figure 5 ,as well as Figures 11 to 13The arrows indicating the force are only for showing direction and do not represent that the force acts only at that location or represent the magnitude of the force. It is understood that the support member 30 and the support portion 22 have surface contact rather than point or line contact, thus ensuring relatively uniform force transmission.

[0086] In an embodiment not shown in the figure, the support portion may consist only of a thicker transverse flange, with a first stress-bearing area formed on the upper surface of the transverse flange and a second stress-bearing area formed on the inner end face of the transverse flange. That is, the first support portion is supported and cooperated with the upper surface of the transverse flange, and the second support portion is supported and cooperated with the inner end face of the transverse flange.

[0087] like Figure 1 and Figure 14 As shown, the pot body assembly also includes an outer shell 50, and the pot body 10, heat preservation cover 20, support member 30 and heating plate 40 are all disposed inside the outer shell 50.

[0088] like Figure 14 and Figure 15 As shown, this application also provides a cooking appliance. An embodiment of the cooking appliance of this application includes a pot body assembly, wherein the pot body assembly is the aforementioned pot body assembly. The aforementioned pot body assembly can effectively solve the problem of easy deformation of the support edge on the heat preservation cover in related technologies, and the cooking appliance having the aforementioned pot body assembly also has the aforementioned advantages.

[0089] like Figure 14 and Figure 15 As shown, the cooking appliance also includes a lid assembly 60, which is detachably disposed above the pot body assembly.

[0090] In the description of this utility model, it should be understood that "multiple" means two or more. 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.

[0091] 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. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0092] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0093] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
