Description

Technical Field

[0001] This utility model belongs to the field of kitchen appliance technology, specifically relating to an electromagnetic cooking appliance. Background Technology

[0002] Because electromagnetic heating enables non-contact heating and is more efficient than heating plates, cooking appliances using electromagnetic heating are becoming increasingly popular in the market. The electromagnetic rice cooker is one such common electromagnetic cooking appliance. Its pot contains an electromagnetic coil, and its core principle is to use electromagnetic induction to generate an induced current inside the metal inner pot, causing the inner pot itself to heat up and thus heating the food inside.

[0003] To improve the overall quality, many induction rice cookers on the market are equipped with metal outer covers. However, due to the limitations of daily use, rice cookers cannot be too large. Therefore, the metal outer cover is close to the induction coil inside. It is very likely that the induction coil will affect the metal outer cover and cause it to heat up. This will eventually lead to local overheating of the metal outer cover, which will greatly affect the user experience.

[0004] Furthermore, due to the gap between the metal casing and the internal components, and the fact that the metal casing is a thin-walled structure, it is more prone to deformation when it is squeezed, dropped, or bumped during transportation due to a lack of support. This is especially true along the long side of the metal casing, where the increased length further weakens the structural strength, making it more susceptible to collapse. Utility Model Content

[0005] This utility model provides an electromagnetic cooking appliance to solve the problems of electromagnetic induction of the electromagnetic coil easily affecting the metal casing, causing the metal casing to heat up and be unsuitable for user use, and the low structural strength of the metal casing, which makes it prone to collapse under external force.

[0006] The technical solution adopted in this utility model is as follows:

[0007] An electromagnetic cooking appliance includes a pot body, which includes a metal outer cover and an electromagnetic coil located inside the metal outer cover. At least one reinforcing component is disposed between the outer periphery of the electromagnetic coil and the metal outer cover. The reinforcing component includes a reinforcing member and a magnetic shielding member. The reinforcing member can abut against the metal outer cover to support the metal outer cover, and the magnetic shielding member is fixed to the reinforcing member.

[0008] In this invention, at least one reinforcing component is provided between the outer periphery of the electromagnetic coil and the metal casing. This reinforcing component includes a reinforcing member and a magnetic shielding member. The reinforcing member provides support for the metal casing. When the metal casing is subjected to inward compressive force from the outside, the reinforcing member can abut against the metal casing from the inside, thereby resisting deformation of the metal casing and preventing large-area deep collapse. The magnetic shielding member blocks the magnetic field of the electromagnetic coil, reducing the influence of the magnetic field on the metal casing and reducing the electromagnetic induction generated by the metal casing. This prevents the metal casing from overheating and excessively rising in temperature, keeping the metal casing at a lower temperature, improving the user's tactile experience, and facilitating use.

[0009] Furthermore, the magnetic shielding component is fixed to the reinforcing component, allowing them to form a single assembly that can be installed and disassembled as a whole. During assembly, the magnetic shielding component can be fixed to the reinforcing component first, and then the reinforcing component can be assembled between the metal casing and the electromagnetic coil. This allows for the simultaneous installation of both the reinforcing component and the magnetic shielding component in a single assembly operation, eliminating the need for separate installations. This simplifies the assembly process, especially for models with limited space between the electromagnetic coil and the metal casing, significantly improving assembly efficiency and reducing assembly difficulty.

[0010] The metal outer cover has a first sidewall and a second sidewall along the circumference. The length of the first sidewall is greater than the length of the second sidewall. The first sidewall is located on the left and right sides of the pot body, and the second sidewall is located on the front and rear sides of the pot body. There are two reinforcing components, which are arranged opposite each other in the radial direction of the electromagnetic coil between the electromagnetic coil and the first sidewall.

[0011] In this design, the first sidewall is longer than the second sidewall, resulting in relatively weaker structural strength. Furthermore, the first sidewall is closer to the electromagnetic coil, making it more susceptible to the coil's magnetic field. Therefore, placing the reinforcing component between the first sidewall and the electromagnetic coil not only provides targeted support to the first sidewall, preventing collapse and deformation, but also effectively isolates it from the electromagnetic coil's magnetic field, reducing the possibility of electromagnetic induction and induced current, thus preventing excessive temperature rise. Additionally, since the first sidewalls are located on the left and right sides of the pot, users typically hold the pot with both hands on either side, directly contacting and compressing the first sidewalls. This design effectively reduces the temperature rise of the first sidewalls, improves support, enhances the user's grip, and prevents deformation, further improving the user experience.

[0012] The reinforcing member has a surrounding rib protruding toward the electromagnetic coil, the surrounding rib forming a mounting position, and the magnetic shielding member is disposed within the mounting position.

[0013] In this design, the reinforcing ribs protruding towards the electromagnetic coil form the mounting position. This serves two purposes: firstly, it positions the magnetic shielding component, stabilizing the relative positions of the magnetic shielding component and the reinforcing component, reducing assembly difficulty; secondly, it prevents relative movement between the magnetic shielding component and the reinforcing component when the reinforcing component is compressed by the metal casing, thus limiting the magnetic shielding component and maintaining their fixed positions. Thirdly, the ribs also enhance the structural strength of the reinforcing component, making it less prone to deformation when compressed by the metal casing, thereby providing stable support to the metal casing.

[0014] The mounting position is provided with a first positioning structure, and the magnetic shielding component is provided with a second positioning structure. One of the first positioning structure and the second positioning structure is a positioning groove, and the other is a positioning rib that is inserted and engaged with the positioning groove.

[0015] In this design, the insertion and cooperation of the first and second positioning structures further improves the positioning effect of the magnetic shielding component and the reinforcing component, limiting the installation angle and direction of the magnetic shielding component, thereby ensuring a good magnetic shielding effect. At the same time, the insertion and cooperation of the positioning groove and the positioning rib makes positioning and assembly simpler and more convenient. Assembly personnel can clearly see the relative positions of the positioning rib and the positioning groove, thus completing the insertion and cooperation.

[0016] The mounting position is provided with a limiting rib protruding towards the electromagnetic coil. The limiting rib can cooperate with the magnetic shielding component to provide a heat dissipation gap between the magnetic shielding component and the side wall of the mounting position.

[0017] In this solution, during the cooking process, the magnetic field generated by the electromagnetic coil and the heat transfer from the cookware inside the metal casing may cause the temperature of the magnetic shielding component or the reinforcing component to rise. By using the limiting rib to abut against the magnetic shielding component, a heat dissipation gap is created between the magnetic shielding component and the reinforcing component, allowing the heat from both to dissipate in a timely manner. This prevents the two components from being tightly fitted together, which would cause heat to accumulate. This not only ensures the service life but also prevents the heat from being further transferred to the metal casing, thus avoiding the temperature rise of the metal casing.

[0018] The reinforcing member has a mounting post protruding toward the electromagnetic coil, and the magnetic shielding member is provided with at least two elastic ribs. Each elastic rib has a connecting end that connects to the magnetic shielding member and a free end. The free end forms a mounting opening, and the mounting opening is interference-fitted with the mounting post.

[0019] In this design, the reinforcing member and the magnetic shielding member are fixed by an interference fit. The elastic ribs on the magnetic shielding member form a mounting opening. When inserted with the mounting post, the mounting post pushes the free end of the elastic rib to swing around the connection end, increasing the opening area of ​​the mounting opening and allowing the mounting post to pass through. Under the elastic force of the elastic rib itself, the free end forms a clamping force from the outer periphery to the inwards on the mounting post, thereby clamping and fixing the mounting post. This fixing method eliminates the need for machining clips, screw holes, or other structures, and also eliminates the need for additional fasteners such as screws. While ensuring the stability of the fixing, it simplifies the fixing operation and saves costs.

[0020] The mounting post has an insertion end facing the electromagnetic coil and a locking end away from the electromagnetic coil, and the cross-sectional area of ​​the mounting post gradually increases from the insertion end to the locking end.

[0021] In this design, as the magnetic shielding component moves along the mounting post, the cross-sectional area of ​​the mounting post gradually increases. Initially, the contact force between the mounting post and the elastic rib is small or even nonexistent, making the connection smoother and easier to perform. As the magnetic shielding component slides along the mounting post, the gap between the mounting post and the inner wall of the mounting opening gradually decreases until it comes into contact. If the magnetic shielding component continues to move along the mounting post, the contact force of the elastic rib on the mounting post increases, making the connection between the magnetic shielding component and the mounting post increasingly secure. If the connection between the magnetic shielding component and the mounting post becomes loose, the larger portion of the mounting post's cross-sectional area can be moved along the insertion direction to contact the elastic rib, thus restoring or even strengthening the fixing effect. The adjustment method is simple and quick.

[0022] The pot body also includes a middle ring located above the metal outer cover. The electromagnetic coil is fastened to the middle ring. The middle ring has a panel, and the bottom surface of the panel is provided with reinforcing ribs. The reinforcing members are provided with insertion grooves that cooperate with the reinforcing ribs.

[0023] In this design, the reinforcing ribs on the bottom of the panel enhance its structural strength. The reinforcing members are fitted with insertion slots that engage with the ribs, improving the positioning of the reinforcing components and the central ring. This ensures the reinforcing components are properly installed, providing excellent support and magnetic shielding for the metal casing. This design eliminates the need for an additional positioning structure on the central ring; instead, the reinforcing ribs form the positioning structure, eliminating the need for structural modifications to the central ring. This facilitates the addition of reinforcing components to existing models, saving on retrofit costs. Furthermore, the multiple reinforcing ribs arranged circumferentially along the central ring allow for adjustable positioning of the reinforcing components around the pot body, increasing the flexibility of installation and meeting the needs of different models. Additionally, the contact between the reinforcing ribs and the reinforcing components creates downward pressure on the reinforcing components after installation, ensuring a more secure position and fixation.

[0024] The panel has an outer wall and an inner wall. The outer wall surrounds the outer periphery of the inner wall. A reinforcing rib is located between the outer wall and the inner wall. The reinforcing member also has a surrounding rib protruding towards the inside of the electromagnetic coil. The surrounding rib abuts against the inner wall.

[0025] In this design, the reinforcing member can be inserted and positioned with the reinforcing rib. Simultaneously, the reinforcing member's surrounding rib abuts against the inner wall of the panel. This allows the reinforcing member to contact and position itself with the central ring in both directions (vertical and horizontal), improving its positioning accuracy. Furthermore, the inner wall, through the surrounding rib, provides outward support to the reinforcing member, collectively supporting the metal casing. When the metal casing deforms inward and contacts the reinforcing member, the compressive force is transmitted to the inner wall through the reinforcing member, allowing the panel to share some of the force. This reduces the risk of the reinforcing member deforming or being damaged due to excessive stress, thus losing its support for the metal casing.

[0026] The pot body also includes a base located below the metal outer cover. The base is fastened to the middle ring, and the reinforcing member also has an abutting part that abuts against the base so that the base and the middle ring clamp and fix the reinforcing member.

[0027] In this solution, the reinforcing component is clamped and fixed from the upper and lower sides of the metal casing by the central ring and the base. The reinforcing component is kept in a stable position by the clamping force on the upper and lower sides. While ensuring the stability of the fixation, the assembly difficulty of the reinforcing component is reduced, and no additional parts are needed to complete the fastening. This not only simplifies the structure of the reinforcing component, but also saves costs. Attached Figure Description

[0040] Many specific details are set forth in the following description in order to provide a full understanding of the present invention.

[0044] like Figure 1 As shown, an electromagnetic cooking appliance includes a pot body, which includes a metal outer cover 1 and an electromagnetic coil 2 located inside the metal outer cover 1. At least one reinforcing component 3 is provided between the outer periphery of the electromagnetic coil 2 and the metal outer cover 1. The reinforcing component 3 includes a reinforcing member 31 and a magnetic shielding member 32. The reinforcing member 31 can abut against the metal outer cover 1 to support the metal outer cover 1, and the magnetic shielding member 32 is fixed to the reinforcing member 31.

[0045] like Figure 1 , Figure 2 As shown, the metal outer casing 1 has an annular wall structure, surrounding the outer periphery of the electromagnetic coil 2 to form the outer wall 412 of the pot body. Preferably, the magnetic shielding component 32 has a plate-like structure.

[0046] It should be noted that in the initial state (the state where the metal casing 1 is not concave), the reinforcing member 31 may or may not be in contact with the metal casing 1. When they are in contact, once the metal casing 1 tends to deform inward, the reinforcing member 31 can promptly provide support for the metal casing 1 to resist its concave deformation. When they are not in contact, a certain deformation space is left for the metal casing 1. When the concave deformation of the metal casing 1 is large enough, the reinforcing member 31 will only apply an outward supporting force to the metal casing 1 after it comes into contact with it.

[0047] In this invention, at least one reinforcing component 3 is provided between the outer periphery of the electromagnetic coil 2 and the metal casing 1. The reinforcing component 3 includes a reinforcing member 31 and a magnetic shielding member 32. The reinforcing member 31 provides support for the metal casing 1. When the metal casing 1 is subjected to inward compressive force from the outside, the reinforcing member 31 can abut against the metal casing 1 from the inside, thereby resisting deformation of the metal casing 1 and preventing large-area deep collapse. The magnetic shielding member 32 can block the magnetic field of the electromagnetic coil 2, reducing the influence of the magnetic field on the metal casing 1 and reducing the electromagnetic induction generated by the metal casing 1. This prevents the metal casing 1 from being overheated and excessively heated, keeping the metal casing 1 at a lower temperature, improving the user's tactile experience, and facilitating use.

[0048] Furthermore, the magnetic shielding component 32 is fixed to the reinforcing component 31, allowing them to form a single assembly that can be installed and disassembled as a whole. During assembly, the magnetic shielding component 32 can be fixed to the reinforcing component 31 first, and then the reinforcing component 31 can be assembled between the metal outer casing 1 and the electromagnetic coil 2. This allows for the simultaneous installation of both the reinforcing component 31 and the magnetic shielding component 32 in a single assembly operation, eliminating the need for separate installations. This simplifies the assembly process, especially for models with limited space between the electromagnetic coil 2 and the metal outer casing 1. The simplified assembly process significantly improves assembly efficiency and reduces assembly difficulty.

[0049] As a preferred embodiment of this utility model, such as Figure 1 As shown, the metal outer cover 1 has a first sidewall 11 and a second sidewall 12 along the circumferential direction. The length of the first sidewall 11 is greater than the length of the second sidewall 12. The first sidewall 11 is located on the left and right sides of the pot body, and the second sidewall 12 is located on the front and rear sides of the pot body. There are two reinforcing components 3, which are arranged opposite to each other in the radial direction of the electromagnetic coil 2 between the electromagnetic coil 2 and the first sidewall 11.

[0050] Specifically, such as Figure 1 As shown, the metal outer casing 1 forms a rectangular area. The first sidewall 11 is located on the left and right sides, and the second sidewall 12 is located on the front and back sides. The first sidewall 11 and the second sidewall 12 are connected by an arc. It can be understood that when the user uses the cooking utensil, the side facing the user is the front side, and the side away from the user is the back side. The left and right sides are arranged opposite each other in a direction perpendicular to the front and back direction.

[0051] The first sidewall 11 is longer than the second sidewall 12, so its structural strength is relatively weaker. At the same time, the first sidewall 11 is closer to the electromagnetic coil 2 and is more susceptible to the magnetic field of the electromagnetic coil 2. Therefore, the reinforcing component 3 is placed between the first sidewall 11 and the electromagnetic coil 2. This not only provides targeted support for the first sidewall 11 to prevent it from collapsing and deforming, but also effectively isolates the magnetic field of the electromagnetic coil 2, reducing the possibility of electromagnetic induction and induced current in the first sidewall 11, and preventing the temperature of the first sidewall 11 from rising excessively.

[0052] Furthermore, since the first sidewall 11 is located on the left and right sides of the pot body, when users move the cooking utensils, they usually hold them with both hands on the left and right sides of the pot body, which means they are in direct contact with the first sidewall 11 on the left and right sides of the pot body and exert inward pressure on the first sidewall 11. Therefore, this solution effectively reduces the temperature rise of the first sidewall 11 and improves the support for the first sidewall 11, which also makes the user's grip feel better and prevents the first sidewall 11 from deforming, further improving the user experience.

[0053] Of course, in other embodiments, the reinforcing components 3 can be of any number and can be disposed in any region along the circumferential direction of the electromagnetic coil 2. For example, there can be four reinforcing components 3, with one reinforcing component 3 disposed between each of the first sidewall 11, the second sidewall 12 and the electromagnetic coil 2. Alternatively, multiple reinforcing components 3 can be evenly spaced along the circumference of the electromagnetic coil 2.

[0054] In a preferred embodiment of this utility model, such as Figure 2 , Figure 4 As shown, the reinforcing member 31 has a surrounding rib 311 protruding toward the electromagnetic coil 2, the surrounding rib 311 forming a mounting position 312, and the magnetic shielding member 32 is disposed within the mounting position 312.

[0055] The reinforcing member 31, with its protruding reinforcing rib 311 facing the electromagnetic coil 2, forms a mounting position 312. This position serves two purposes: firstly, it positions the magnetic shielding member 32, stabilizing the relative position of the magnetic shielding member 32 and the reinforcing member 31, reducing assembly difficulty; secondly, it prevents relative movement between the magnetic shielding member 32 and the reinforcing member 31 when the reinforcing member 31 is compressed by the metal casing 1, thus limiting the magnetic shielding member 32 and maintaining their fixed position. Thirdly, the reinforcing rib 311 also enhances the structural strength of the reinforcing member 31, making it less prone to deformation when compressed by the metal casing 1, thereby providing stable support to the metal casing 1.

[0056] Specifically, such as Figure 2 , Figure 4As shown, the reinforcing rib 311 is provided on the edge of the reinforcing member 31 and protrudes toward the electromagnetic coil 2 to increase the area of ​​the mounting position 312, thereby accommodating a larger area of ​​the magnetic shielding member 32.

[0057] Furthermore, such as Figure 2 , Figure 4 As shown, a first positioning structure is provided in the mounting position 312, and a second positioning structure is provided in the magnetic shielding component 32. One of the first positioning structure and the second positioning structure is a positioning groove 321, and the other is a positioning rib 314 that is inserted and engaged with the positioning groove 321.

[0058] By interlocking the first and second positioning structures, the positioning effect of the magnetic shielding component 32 and the reinforcing component 31 can be further improved, limiting the installation angle and direction of the magnetic shielding component 32, thereby ensuring a good magnetic shielding effect. At the same time, the interlocking method of the positioning groove 321 and the positioning rib 314 also makes positioning and assembly simpler and more convenient. Assemblers can clearly see the relative position of the positioning rib 314 and the positioning groove 321, thus completing the interlocking.

[0059] In one specific embodiment, such as Figure 2 , Figure 4 As shown, the positioning rib 314 is provided on one side of the surrounding rib 311 and protrudes towards the interior of the mounting position 312, and the positioning groove 321 is provided on the edge of the magnetic shielding component 32. During assembly, the edge of the magnetic shielding component 32 with the positioning groove 321 is aligned with the edge of the reinforcing member 31 with the positioning rib 314, thereby limiting the installation angle of the magnetic shielding component 32 from thermal constraints.

[0060] Of course, the positioning rib 314 can also be set at other positions on the reinforcing member 31, and the positioning groove 321 can be opened at the corresponding position on the magnetic shielding member 32. Alternatively, the positioning rib 314 can also be set on the magnetic shielding member 32, and the positioning groove 321 can be opened on the reinforcing member 31 to allow the two to be inserted and positioned. This is not limited here.

[0061] Preferably, such as Figure 2 , Figure 4 As shown, a limiting rib 313 protruding towards the electromagnetic coil 2 is provided in the mounting position 312. The limiting rib 313 can cooperate with the magnetic shielding component 32 to provide a heat dissipation gap between the magnetic shielding component 32 and the side wall of the mounting position 312.

[0062] During cooking, the magnetic field generated by the electromagnetic coil 2 and the heat transfer from the cookware inside the metal casing 1 may cause the temperature of the magnetic shielding component 32 or the reinforcing component 31 to rise. By abutting the magnetic shielding component 32 with the limiting rib 313, a heat dissipation gap is created between the magnetic shielding component 32 and the reinforcing component 31, allowing the heat from both to dissipate in time and preventing the two from being tightly fitted together and causing heat accumulation. This ensures the service life and prevents the heat from being further transferred to the metal casing 1, thus preventing the temperature of the metal casing 1 from rising.

[0063] This utility model does not limit the fixing method of the reinforcing member 31 and the magnetic shielding member 32. In a preferred embodiment, such as Figure 4 As shown, the reinforcing member 31 has a mounting post 316 protruding toward the electromagnetic coil 2, and the magnetic shielding member 32 is provided with at least two elastic ribs 323. The elastic ribs 323 have a connecting end connected to the magnetic shielding member 32 and a free end. The free end forms a mounting opening 322, and the mounting opening 322 is interference-fitted with the mounting post 316.

[0064] The reinforcing member 31 and the magnetic shielding member 32 are fixed by an interference fit. The elastic ribs 323 on the magnetic shielding member 32 form a mounting opening 322. When inserted with the mounting post 316, the mounting post 316 pushes the free end of the elastic rib 323 to swing around the connection end, thereby increasing the opening area of ​​the mounting opening 322 and allowing the mounting post 316 to pass through. Under the elastic force of the elastic rib 323 itself, the free end forms a clamping force from the outer periphery to the inward on the mounting post 316, thereby clamping and fixing the mounting post 316. This fixing method does not require the processing of clips, screw holes, or other structures, nor does it require the use of screws or other additional fasteners. While ensuring the stability of the fixing, it makes the fixing operation simpler and saves costs.

[0065] Preferably, such as Figure 4 As shown, the reinforcing member 31 is provided with a limiting rib 313 that can abut against the magnetic shielding member 32. The limiting rib 313 passes through the mounting post 316 so that the limiting rib 313 also plays a role in structurally reinforcing the mounting post 316.

[0066] Specifically, such as Figure 4 As shown, there are four elastic ribs 323, which are evenly spaced along a circular path so that the free ends surround the mounting opening 322, and the elastic ribs 323 surround the outer periphery of the mounting opening 322. Of course, the number of elastic ribs 323 can also be other than that, which is not limited here.

[0067] Furthermore, such as Figure 4 As shown, the mounting post 316 has an insertion end facing the electromagnetic coil 2 and a locking end away from the electromagnetic coil 2, and the cross-sectional area of ​​the mounting post 316 gradually increases from the insertion end to the locking end.

[0068] As the magnetic shielding component 32 moves along the mounting post 316, the cross-sectional area of ​​the mounting post 316 gradually increases. Initially, the contact force between the mounting post 316 and the elastic rib 323 is small or even nonexistent, making the insertion smoother and easier. As the magnetic shielding component 32 slides along the mounting post 316, the gap between the mounting post 316 and the inner wall of the mounting opening 322 gradually decreases until it comes into contact. If the magnetic shielding component 32 continues to move along the mounting post 316, the contact force of the elastic rib 323 on the mounting post 316 increases, making the connection between the magnetic shielding component 32 and the mounting post 316 increasingly secure. If the connection between the magnetic shielding component 32 and the mounting post 316 becomes loose, the larger portion of the cross-sectional area of ​​the mounting post 316 can be slid along the insertion direction to contact the elastic rib 323, thus restoring or even strengthening the fixing effect. This adjustment method is simple and quick.

[0069] Of course, in other embodiments, the reinforcing member 31 and the magnetic shielding member 32 can also be fixedly connected by other means, such as screw connection, snap-fit ​​connection, etc., as long as the magnetic shielding member 32 and the reinforcing member 31 can be fixed, and no limitation is made here.

[0070] As a preferred embodiment of this utility model, such as Figure 2 , Figure 3 As shown, the pot body also includes a middle ring 4 located above the metal outer cover 1. The electromagnetic coil 2 is fastened to the middle ring 4. The middle ring 4 has a panel 41. The bottom surface of the panel 41 is provided with a reinforcing rib 411. The reinforcing member 31 is provided with a plug groove 315 that is inserted and matched with the reinforcing rib 411.

[0071] Specifically, the middle ring 4 includes a panel 41 and a downwardly extending connecting post 42. The panel 41 is located above the metal outer cover 1 and forms the top surface of the pot body. The connecting post 42 is used to securely connect with the electromagnetic coil 2 and the base 5 below the metal outer cover 1.

[0072] The reinforcing ribs 411 on the bottom surface of panel 41 enhance the structural strength of panel 41. The reinforcing member 31 has insertion slots 315 that engage with the reinforcing ribs 411, improving the positioning effect between the reinforcing component 3 and the middle ring 4, ensuring the reinforcing component 3 is properly installed, thus providing good support and magnetic shielding for the metal casing 1. In this solution, there is no need to add an additional positioning structure to the middle ring 4; instead, the reinforcing ribs 411 form the positioning structure, eliminating the need for structural modifications to the middle ring 4. This facilitates the installation of the reinforcing component 3 on existing models, saving on modification costs. Furthermore, the contact between the reinforcing ribs 411 and the reinforcing member 31 creates downward pressure on the reinforcing member 31 after installation, making the position and fixation of the reinforcing member 31 more secure.

[0073] Preferably, such as Figure 3As shown, there are multiple reinforcing ribs 411, which are spaced apart along the circumference of the panel 41. The multiple reinforcing ribs 411 arranged along the circumference of the central ring 4 make the positioning position of the reinforcing component 3 in the circumference of the pot body adjustable, thereby improving the flexibility of the installation position 312 of the reinforcing component 3 and meeting the needs of different models.

[0074] Preferably, such as Figure 3 As shown, panel 41 has an outer sidewall 412 and an inner sidewall 413. The outer sidewall 412 surrounds the outer periphery of the inner sidewall 413. A reinforcing rib 411 is located between the outer sidewall 412 and the inner sidewall 413. The reinforcing member 31 also has a surrounding rib 311 protruding toward the interior of the electromagnetic coil 2. The surrounding rib 311 abuts against the inner sidewall 413.

[0075] The reinforcing member 31 can be inserted and positioned with the reinforcing rib 411. Simultaneously, the surrounding rib 311 of the reinforcing member 31 also abuts against the inner wall 413 of the panel 41. This allows the reinforcing member 31 to contact and position itself with the central ring 4 in both directions (vertical and horizontal), improving the positioning accuracy of the reinforcing member 31. Furthermore, the inner wall 413 can also provide outward support to the reinforcing member 31 through the surrounding rib 311, jointly supporting the metal outer cover 1. When the metal outer cover 1 deforms inward and contacts the reinforcing member 31, the compressive force is transmitted through the reinforcing member 31 to the inner wall 413, allowing the panel 41 to share some of the force. This reduces the risk of the reinforcing member 31 deforming or being damaged due to excessive force, thus losing its support for the metal outer cover 1.

[0076] like Figure 2 , Figure 3 As shown, the pot body also includes a base 5 located below the metal outer cover 1. The base 5 is fastened to the middle ring 4. The reinforcing member 31 also has an abutting part that abuts against the base 5 so that the base 5 and the middle ring 4 clamp and fix the reinforcing member 31.

[0077] The base 5 is located below the metal outer cover 1, forming the bottom surface of the pot body.

[0078] The reinforcing component 3 is clamped and fixed from the upper and lower sides of the metal outer cover 1 by the middle ring 4 and the base 5. The upper and lower sides of the reinforcing component 3 are clamped and kept in a stable position. While ensuring the stability of the fixation, the assembly difficulty of the reinforcing component 3 is reduced, and no additional parts are needed to complete the fastening. This not only simplifies the structure of the reinforcing component 3, but also saves costs.
