[0002] In existing cooking appliances, the coil assembly is a key component for converting electrical energy into magnetic energy and then generating heat. However, the heating effect at the center of the coil assembly is poor, the magnetic strength of the central magnetic strips is insufficient, and the magnetic force is easily attenuated, resulting in uneven heating. This leads to inaccurate temperature control by the temperature sensor, resulting in poor rice cooking.

[0003] Therefore, there is a need to provide a coil plate assembly and a cooking appliance to at least partially solve the above problems. Utility Model Content

[0004] The utility model description section introduces a series of simplified concepts, which will be further explained in detail in the detailed description section.

[0009] The coil disk, the limiting rib, and the magnetic strip support are integrally formed.

[0010] According to this design, the limiting ribs provide radial inward restraint for the coil, offering a foundation for coil winding and thus improving coil stability. The coordinated arrangement of the limiting ribs, body, and connecting portion also ensures physical separation between the coil and the magnetic strip. The body can correspond to the area where the coil is placed. The body can also extend to areas where no coil is placed, allowing the magnetic strip to be closer to the central axis of the coil base than the coil, thereby strengthening the overall magnetic force, optimizing the magnetic field distribution, and improving heating efficiency. The hollowed-out grooves improve the magnetic penetration and uniformity of the magnetic strip, better utilizing its magnetic properties. The one-piece molding process is simple and requires no additional assembly steps.

[0023] According to this solution, the reinforcing ribs can effectively support the area around the connecting holes and prevent structural weakening caused by the presence of the connecting holes.

[0024] Optionally, the reinforcing rib extends to the coil base.

[0025] According to this scheme, the reinforcing rib is connected to the coil base, and the coil base provides stable support for the reinforcing rib.

[0026] Optionally, the reinforcing rib divides the hollowed-out groove into sub-hollowed-out grooves spaced apart along the circumferential direction of the coil base.

[0031] According to this solution, the aforementioned dimensional limitations help ensure the manufacturing precision and installation accuracy of the magnetic stripe bracket.

[0032] Optionally, the limiting rib is constructed as a ring.

[0033] According to this solution, the circular limiting rib can provide uniform support force, making the magnetic strip support more stable and reliable.

[0034] The limiting rib is connected to the magnetic strip bracket.

[0035] According to this solution, by connecting the limiting ribs and the magnetic strip support, a more integrated structure can be formed, improving the stability of the entire coil assembly.

[0036] Optionally, the center of the coil base is located adjacent to or coincides with the center of the first region.

[0037] According to this scheme, the limiting ribs are reasonably arranged on the coil plate base, and the coil plate assembly can generate a more uniform and stable electromagnetic field when working, thereby improving the efficiency of electromagnetic heating.

[0038] Optionally, the radial inner end and / or radial outer end of the body portion are provided with openings.

[0039] According to this solution, the opening in the main body facilitates the assembly of the magnetic strip and enables heat dissipation during use.

[0040] Optionally, the radially inner end of the connecting portion is provided as an opening.

[0041] According to this design, the opening in the connecting part facilitates the forming of the hollow groove.

[0042] Optionally, the body portion has a strip-shaped structure or a fan-shaped annular structure; and / or

[0043] The connecting part has a strip-shaped structure or a fan-shaped ring structure.

[0045] Optionally, a plurality of magnetic strip supports are spaced apart along the circumferential direction of the coil base, adjacent body portions are spaced apart, and adjacent connecting portions are spaced apart or connected.

[0046] According to this solution, by setting the spacing of the main body, the coil slots are formed at intervals, which ensures that the coil is evenly supported, thereby optimizing the overall structure of the coil disk assembly. This satisfies both structural strength and heat dissipation performance and electromagnetic field distribution, achieving a balance in multiple aspects.

[0047] Optionally, the distance between the radial inner end of the magnetic strip groove and the coil base is greater than the distance between the radial outer end of the magnetic strip groove and the coil base.

[0048] According to this scheme, the magnetic strip groove allows the magnetic strip to be set at a certain angle to the coil base, thereby expanding the magnetic field range and making the magnetic field lines denser in the target area, thus improving the interaction efficiency between the magnetic field and the coil.

[0049] Optionally, the height of the limiting rib is greater than the thickness of the coil; and / or

[0050] The thickness of the limiting rib is 1-2mm.

[0051] According to this design, the height of the limiting rib is greater than the thickness of the coil. The limiting rib effectively blocks the beginning of the coil, preventing displacement during assembly or operation, thus ensuring the stability and reliability of the entire coil structure.

[0052] Optionally, the coil assembly satisfies at least one of the following conditions:

[0053] The length of the main body is 25-55mm;

[0054] The width of the main body is 14-20mm;

[0056] The thickness of the sidewall of the magnetic strip groove is 1-2 mm;

[0057] The distance between the main body and the coil base located in the second region is 1-6 mm.

[0058] According to this design, the gap in the coil slots varies with the height of the coil stack, allowing the main body to effectively hold the coil in place and prevent it from falling off the coil tray. This ensures the coil is tightly attached to the bottom of the main body and the coil tray, guaranteeing coil consistency and thus ensuring stable and reliable heating.

[0059] Optionally, the magnetic strip support further includes a fixing post located at the periphery of the opening of the magnetic strip groove, the fixing post being deformable to confine the magnetic strip within the magnetic strip groove.

[0060] According to this solution, the deformable characteristics of the fixing column not only make the fixing operation simple and quick, but also ensure reliable fixing effect, which can ensure that the magnetic strip is stably installed in the magnetic strip groove.

[0061] Optionally, the length of the fixing post is 4-8 mm; and / or

[0062] The height of the fixing post is 1-3mm; and / or

[0063] The thickness of the fixing column is 1-2 mm.

[0064] According to this solution, the length and height of the fixing column are limited to ensure the stable fixation of the magnetic strip within the magnetic strip groove.

[0065] Optionally, the coil holder includes a bottom and a side, with a coil wound on the bottom, or both the bottom and the side are wound with coils; wherein,

[0109] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of the present invention is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art.

[0110] This utility model provides a cooking utensil. The cooking utensil includes a lid and a pot body. The pot body is used for cooking food, and the lid is used to cover the pot body. For example, the lid is connected to the pot body in an openable and closable manner to cover the pot body. When the lid covers the pot body, a cooking space is formed between the lid and the pot body. The pot body has a cylindrical inner pot storage section. The inner pot can be fixedly installed in the inner pot storage section, or it can be freely placed into or removed from the inner pot storage section for easy cleaning. The inner pot is usually made of metal and has a circular opening on its upper surface for holding materials to be heated, such as rice or soup. The pot body includes a heating device for heating the inner pot.

[0111] The cooking appliance according to this utility model can be a rice cooker, electric pressure cooker or other cooking appliance with electromagnetic heating function, and in addition to cooking rice, the cooking appliance can also have various functions such as cooking porridge.

[0112] An electromagnetic heating device can be installed inside the pot. This device includes a coil assembly. The coil assembly is located below the inner pot and is used to heat the food inside. The inner pot is made of a magnetically conductive material.

[0113] The following is combined Figures 1 to 11 This invention describes a coil disk assembly provided by the present invention.

[0114] Reference Figures 1-11 The coil assembly includes a coil base 100, a magnetic strip support 200, and a limiting rib 300.

[0115] The limiting rib 300 is connected to the coil base 100. One surface of the coil base 100 in the thickness direction DW is the first surface 101. Specifically, the limiting rib 300 is connected to the first surface 101. The limiting rib 300 is constructed as a ring, meaning the limiting rib 300 itself is a closed ring structure. Optionally, the shape of the limiting rib 300 can not only be a traditional circle or square, but can also be designed as other irregular structures according to actual needs. The limiting rib 300 can also be constructed as multiple limiting ribs 300 arranged in a ring array. That is, multiple limiting ribs 300 are arranged in a ring, and the limiting rib 300 and its extension line together form a ring or near-ring structure. Optionally, the limiting rib 300 is constructed as a circular ring.

[0116] The limiting rib 300 defines a first region located circumferentially inward and a second region located circumferentially outward. The second region is suitable for winding the coil 500. The setting of the limiting rib 300 constitutes a radially inward limiting of the coil 500, providing a basis for winding the coil 500, thereby improving the stability of the coil 500. In this embodiment, radial refers to the direction from the center of the coil base 100 to the periphery.

[0117] Optionally, the center of the coil base 100 is positioned adjacent to or coincides with the center of the first region. This ensures a reasonable layout of the limiting ribs on the coil base 100, allowing the coil assembly to generate a more uniform and stable electromagnetic field during operation, thereby improving the efficiency of electromagnetic heating. The positioning of the center of the coil base 100 adjacent to the center of the first region refers to potential errors that may occur during the molding of the coil assembly; or it could mean that the distance between the center of the coil base 100 and the center of the first region is a designed distance.

[0118] The magnetic strip support 200 accommodates the magnetic strip 400, and electromagnetic heating is achieved through the interaction between the magnetic field generated by the magnetic strip 400 and the magnetic field generated by the coil 500. The magnetic strip support 200 includes a body portion 210 and a connecting portion 220, which connects the body portion 210 to the coil base 100. The body portion 210 has a magnetic strip groove 201, and the connecting portion 220 has a hollow groove 221 connected to the magnetic strip groove 201. Optionally, the magnetic strip groove 201 is located on the side of the body portion 210 opposite to the first surface 101, and is used to accommodate the magnetic strip 400. The hollow groove 221 improves the magnetic penetration and uniformity of the magnetic strip 400, thus better utilizing its magnetic properties. Optionally, the hollow groove 221 can also house the magnetic strip 400.

[0119] The main body 210 extends from the first region to the second region. The main body 210 can correspond to the region where the coil 500 is installed. The main body 210 can also extend to the region where the coil 500 is not installed, so the magnetic strip 400 can be closer to the central axis of the coil base 100 than the coil 500, thereby strengthening the overall magnetic force, optimizing the magnetic field distribution, and improving the heating efficiency.

[0120] The main body 210 located in the first region is connected to the coil base 100 via a connecting part 220. The connecting part 220 is physically spaced from the coil 500 by a limiting rib 300.

[0121] The body portion 210 located in the second region is spaced apart from the coil base 100. That is, the body portion 210, the limiting rib 300, and the first surface 101 define a coil groove 202 for accommodating the coil 500.

[0122] In this design, the limiting rib 300 ensures that both the magnetic strip groove 201 and the hollow groove 221 are spaced apart from the coil groove 202, preventing direct contact between the magnetic strip 400 and the coil 500 and optimizing the magnetic field distribution. The combination of the limiting rib 300 and the magnetic strip support 200 effectively separates the magnetic strip 400 from the coil 500. Specifically, the magnetic strip 400 in the magnetic strip groove 201 is spaced apart from the coil 500 by the magnetic strip support 200. Optionally, the hollow groove 221 can also house the magnetic strip 400, which is then spaced apart from the coil 500 by the limiting rib 300. The relative positions of the magnetic strip 400 and the coil 500 work together to enhance the magnetic field distribution, resulting in a more uniform and stable magnetic field.

[0123] In this design, the axial groove 221 corresponds to the magnetic strip groove 201, and the radial groove 221 corresponds to the coil groove 202. As mentioned above, the coil 500 is not located below the radially inner end of the magnetic strip 400. The axial groove 221 improves the magnetic penetration and uniformity of the magnetic strip 400, thus enhancing its magnetic properties. The radially inner end is the end facing the center of the coil base 100. In this design, the magnetic strip support 200 and the coil base 100 are made of plastic. Generally, as the thickness of the plastic increases, the shrinkage rate increases accordingly. Optionally, plastic exceeding 3.5 mm in thickness will shrink. In this design, the thickness of the connecting portion 220 is reduced by the axial groove 221, effectively preventing shrinkage due to excessive plastic thickness. Furthermore, the axial groove 221 also aids in heat dissipation.

[0124] In some embodiments of this invention, the hollow slot 221 does not have a magnetic strip 400. Optionally, the magnetic strip 400 is constructed as a cuboid. Due to its regular shape, it can form a stable and uniform magnetic field, reducing inhomogeneity and fluctuations in the magnetic field. The cuboid magnetic strip 400 can utilize space more effectively, reducing unnecessary material waste, thereby reducing the weight of the component and improving the integration and reliability of the component.

[0125] In some other embodiments of this invention, a magnetic strip 400 is mounted in the slot 221. Optionally, the magnetic strip 400 is constructed in an L-shape. The L-shaped magnetic strip 400 can utilize the space of the slot 221 more effectively, thereby forming a more stable and uniform magnetic field in a specific area.

[0126] Based on the above embodiments, a suitable implementation method can be selected according to actual needs.

[0127] In this design, the shape and size of the magnetic strip groove 201 are adapted to the magnetic strip 400. When the magnetic strip 400 is installed in the hollow groove 221, the shape and size of the hollow groove 221 are adapted to the magnetic strip 400. The positional distribution of the magnetic strip groove 201 and the hollow groove 221 ensures that the magnetic strip 400 can generate the required magnetic field distribution. Optionally, the magnetic strip 400 and the magnetic strip support 200 can be connected by an appropriate fixing method. The fixing methods of the magnetic strip 400 and the magnetic strip support 200 include, but are not limited to, adhesive connection and snap-fit ​​connection. During installation, it is necessary to ensure a tight fit between the magnetic strip 400 and the hollow groove 221 to avoid magnetic field leakage or weakening.

[0128] The coil slot 202 is used to place and fix the coil 500. The shape, size, and depth of the coil slot 202 are adapted to the size and shape of the coil 500 to ensure that the coil 500 can be stably installed within the coil slot 202. The coil 500 can be wound within the coil slot 202 and fixed by an appropriate fixing method. The fixing methods of the coil 500 within the coil slot 202 include, but are not limited to, adhesive and clips.

[0129] In this design, the magnetic strip 400 generates the desired magnetic field distribution. The coil 500 stably receives the magnetic field generated by the magnetic strip 400 and converts it into heat or other forms of energy.

[0130] Optionally, a notch is formed at the radially outer end of the body portion 210, spaced apart from the first surface 101, to allow the coil 500 to enter the coil slot 202. The notch facilitates easier entry of the coil 500 into the coil slot 202, simplifying the installation process. The notch also makes the overall structure of the coil assembly more compact and rational. The radially inner end of the body portion 210 is connected to the coil base 100 via a connecting portion 220. The connecting portion 220 is located in the second region, specifically on the side of the limiting rib 300 near the central axis of the coil base 100. The connecting portion 220 does not directly contact the coil 500. Furthermore, due to the extended arrangement of the body portion 210, the magnetic strip groove 201 is closer to the central axis of the coil base 100 than the coil slot 202. The magnetic strip groove 201 extends towards the central axis, and the area perpendicular to the extension is free of the coil 500, thereby strengthening the overall magnetic force, optimizing the magnetic field distribution, and improving heating efficiency. The radial direction refers to the direction from the center of the coil base 100 to its periphery. The inner radial end is the end facing the center. The outer radial end is the end facing the periphery.

[0131] In this solution, the coil base 100, the limiting rib 300, and the magnetic strip bracket 200 are integrally formed, which is simple in molding process and does not require additional assembly steps.

[0132] Optionally, the limiting rib 300 is connected to the magnetic strip support 200. The connection between the limiting rib 300 and the magnetic strip support 200 creates a more integrated structure, improving the stability of the entire coil assembly. Optionally, the limiting rib 300 is located between the magnetic strip support 200 and the coil base 100, providing effective support for the magnetic strip support 200.

[0133] In some embodiments of this invention, the magnetic strip groove 201 extends from the first region to the second region. The magnetic field of the magnetic strip 400 can cover the area where the coil 500 is wound, ensuring that the magnetic field generated by the magnetic strip 400 can act directly and efficiently on the coil 500, resulting in a more uniform and stable magnetic field on the coil 500. Simultaneously, while ensuring performance, the structure of the coil disk assembly is made more compact, improving space utilization. The extension of the magnetic strip groove 201 can also enhance the magnetic effect, making the magnetic field more concentrated and stable.

[0134] In some embodiments of this invention, a connecting hole 203 is provided at the bottom of the magnetic strip groove 201, and the magnetic strip groove 201 is connected to the hollow groove 221 via the connecting hole 203. Optionally, the projection of the connecting hole 203 onto the first surface 101 is located within the projection of the hollow groove 221 onto the first surface 101. This ensures smoother magnetic field transmission and reduces magnetic field loss and interference. The synergistic effect of the connecting hole 203 and the hollow groove 221 can also more effectively dissipate heat, reduce the impact of thermal stress on the material, and improve the reliability and stability of the entire component.

[0135] Based on the above embodiment, a reinforcing rib 222 is provided inside the hollow groove 221. The reinforcing rib 222 does not protrude from the inner wall of the bottom of the magnetic strip groove 201. In this solution, the setting of the reinforcing rib 222 avoids affecting the assembly of the magnetic strip 400.

[0136] Optionally, the reinforcing rib 222 is connected to the inner wall of the hollow groove 221. The reinforcing rib 222 can be stably connected to the hollow groove 221, improving the overall stability and durability of the magnetic strip support.

[0137] Optionally, the reinforcing rib 222 is connected to the wall of the connecting hole 203. And / or, the reinforcing rib 222 is connected to the outer wall of the bottom of the magnetic strip groove 201. In this solution, the reinforcing rib 222 can effectively support the area around the connecting hole 203, preventing structural weakening due to the presence of the connecting hole 203.

[0138] Optionally, the reinforcing rib 222 extends to the coil base 100. That is, the reinforcing rib 222 is connected to the first surface 101, thereby achieving effective support of the reinforcing rib 222 by the coil base 100.

[0139] Based on the above embodiment, the inner and outer radial ends of the reinforcing rib 222 are respectively connected to the periphery of the connecting hole 203 to divide the hollow groove 221 into sub-hollow grooves 2211 spaced along the circumferential direction of the coil base 100. The connection between the reinforcing rib 222 and the periphery of the connecting hole 203, i.e., the connection between the reinforcing rib 222 and the wall of the connecting hole 203 and / or the outer wall of the bottom of the magnetic strip groove 201 forming the connecting hole 203, further improves the overall stability and durability of the magnetic strip support 200. It also simplifies the molding process and mold of the integrally formed coil assembly. The radial length a of the sub-hollow groove 2211 is 1-4 mm. The circumferential length b of the sub-hollow groove 2211 is 2-8 mm. The thickness c of the reinforcing rib 222 is 2-4 mm. These dimensional limitations help ensure the manufacturing precision and installation accuracy of the magnetic strip support 200.

[0140] In some embodiments of this utility model, the radially inner end and / or radially outer end of the body portion 210 are provided with openings. The openings in the body portion 210 facilitate the assembly of the magnetic strip 400 and also enable heat dissipation during use.

[0141] In some embodiments of this utility model, the radially inner end of the connecting portion 220 is open. This opening in the connecting portion 220 facilitates the forming of the hollowed-out groove 221. When the magnetic strip 400 is installed in the hollowed-out groove 221 of the connecting portion 220, the opening at the radially inner end of the connecting portion 220 facilitates the installation of the magnetic strip 400.

[0142] As described above, the radially inner end of the main body 210, the radially outer end of the main body 210, and the inner end of the connecting portion 220 can be configured as open shapes according to actual needs. For example, refer to... Figure 8 The radial inner end of the main body 210 is provided with an opening.

[0143] In some embodiments of this utility model, the main body 210 has a strip-shaped structure or a fan-shaped annular structure. The connecting part 220 has a strip-shaped structure or a fan-shaped annular structure. The structures of the main body 210 and the connecting part 220 can be adapted to the shape of the coil base 100, thereby providing a reasonable coil slot 202 and magnetic strip slot 201. The reasonable design of the coil slot 202 and magnetic strip slot 201 can optimize the magnetic field distribution.

[0144] In some embodiments of this invention, multiple magnetic strip supports 200 are spaced apart along the circumferential direction of the coil base 100. Adjacent body portions 210 are spaced apart, and adjacent connecting portions 220 are spaced apart or connected. The spaced arrangement of the body portions 210 forms spaced coil slots 202, ensuring uniform support for the coil 500 and optimizing the overall structure of the coil assembly. This achieves a balance between structural strength, heat dissipation, and electromagnetic field distribution. In some embodiments, adjacent connecting portions 220 are connected to form a ring structure. This ring structure not only provides stronger structural support but also enhances aesthetics.

[0145] In some embodiments of this invention, the distance between the radially inner end of the magnetic strip groove 201 and the first surface 101 is greater than the distance between the radially outer end of the magnetic strip groove 201 and the first surface 101. That is, when the magnetic strip 400 is installed in the magnetic strip groove 201, the distance between the radially inner end of the magnetic strip 400 and the first surface 101 is greater than the distance between the radially outer end of the magnetic strip 400 and the first surface 101. In other words, the magnetic strip 400 is set at a certain angle to the first surface 101, thereby expanding the magnetic field range and making the magnetic field lines denser in the target area, thus improving the interaction efficiency between the magnetic field and the coil 500.

[0146] The height of the limiting rib 300 is greater than the thickness of the coil 500. The limiting rib 300 effectively blocks the beginning of the coil 500, preventing displacement during assembly or operation, thus ensuring the stability and reliability of the entire coil 500 structure. Accurate coil 500 positioning and a stable structure guarantee electromagnetic induction effects, thereby improving heating efficiency. Optionally, the thickness d of the limiting rib 300 is 1-2 mm. This dimension is set based on considerations of structural stability and support, protection of the coil 500, and reasonable installation.

[0147] Reference Figure 3 and Figure 5The length e of the body portion 210 is 25-55 mm. The width f of the body portion 210 is 14-20 mm. The depth g of the magnetic strip groove 201 is 2-6 mm. The thickness h of the sidewall of the magnetic strip groove 201 is 1-2 mm. The distance between the body portion 210 and the first surface 101 is 1-6 mm, wherein the minimum distance i1 between the body portion 210 and the first surface 101 is 1 mm, and the maximum distance i2 between the body portion 210 and the first surface 101 is 6 mm. In this scheme, the gap of the coil groove 202 varies with the stacking height of the coils 500, so that the body portion 210 can effectively press the coils 500, preventing the coils 500 from falling off the coil disk. This ensures that the coils 500 can be tightly attached to the bottom of the body portion 210 and the first surface 101, ensuring the consistency of the coils 500, thereby ensuring stable and reliable heating.

[0148] In some embodiments of this utility model, the magnetic strip support 200 further includes a fixing post 230. The fixing post 230 is located around the periphery of the opening of the magnetic strip groove 201. The fixing post 230 is deformable to confine the magnetic strip 400 within the magnetic strip groove 201. As mentioned above, the magnetic strip support 200 can be made of plastic. After the magnetic strip 400 is inserted, the fixing post 230 is softened using a hot-melt device and then pressed towards the opening of the magnetic strip groove 201, causing the fixing post 230 to deform. After cooling, the plastic fixing post 230 solidifies to form an inverted buckle, thereby fixing the magnetic strip 400 within the magnetic strip groove 201. The deformable characteristic of the fixing post 230 not only makes the fixing operation simple and quick, but also ensures reliable fixing, guaranteeing that the magnetic strip 400 is stably installed within the magnetic strip groove 201.

[0149] Based on the above embodiment, the height j of the fixing post 230 is 1-3 mm. The length k of the fixing post 230 is 4-8 mm. Understandably, the thickness of the fixing post 230 is the same as the thickness of the sidewall of the magnetic strip groove 201. The design of the length and height of the fixing post 230 must ensure the stable fixation of the magnetic strip 400 within the magnetic strip groove 201. A fixing post 230 that is too short may not provide sufficient fixing force, while a fixing post 230 that is too long may increase manufacturing difficulty and cost. Therefore, a length of 4-8 mm and a height of 1-3 mm is a relatively balanced choice. Furthermore, the fact that the thickness of the fixing post 230 is the same as the sidewall thickness of the magnetic strip groove 201 simplifies the one-piece molding process.

[0150] In this design, the coil holder 100 includes a bottom 110 and a side 120. A coil is wound around the bottom 110, or both the bottom 110 and the side 120 are wound with coils. Different coil winding methods can be selected according to actual needs to achieve efficient energy conversion within a limited space. For example, refer to... Figure 2 and Figure 7 The coil is wound around the sides and bottom. (Refer to...) Figure 9The coils are wound around the bottom, and the bottom coils are divided into two groups, which are arranged radially at intervals.

[0151] Optionally, the bottom 110 is constructed to be flat, and the side 120 extends upward and outward from the periphery of the bottom 110.

[0152] Optionally, the bottom 110 extends upward and outward from the center in a circumferential direction, and the side 120 extends upward and outward from the periphery of the bottom 110 in a circumferential direction.

[0153] The angle and shape of the bottom of the coil holder 100 can be adjusted according to specific application requirements and the shape of the cookware. For example, refer to... Figures 7 to 10 The bottom portion of the coil base 100 where the coil 500 is wound has a flat bottom. (Refer to...) Figures 2 to 3 The portion of the coil base 100 where the coil 500 is wound is constructed such that it extends upward and outward from the center in a circumferential direction.
