Description

Technical Field

[0001] This utility model relates to the field of electromagnetic heating, and in particular to a cooking device and cooking set. Background Technology

[0002] The coil is the core component of electromagnetic heating cooking equipment (such as induction cookers), and its performance directly determines the heat field distribution during electromagnetic heating. Compared to flat induction cookers, concave induction cookers perform better when heating concave-bottomed woks, as the wok walls can also be electromagnetically heated, improving heating uniformity. However, they have the following disadvantages:

[0003] Concave induction cookers have poor compatibility with other types of cookware, especially flat-bottomed frying pans and large and small flat-bottomed soup pots, which are very difficult to heat, or even impossible to heat. In addition, concave induction cookers are very thick and heavy, which reduces their aesthetic appeal and makes them inconvenient to place and store in the kitchen. Their sales are also far lower than those of flat induction cookers.

[0004] Therefore, it is urgent to solve the technical problems of concave induction cookers' poor compatibility with other types of cookware and their overall bulkiness. Utility Model Content

[0005] This utility model provides a cooking device and cooking set to solve the technical problems of poor compatibility of concave induction cookers with other types of cookware and the heavy and bulky nature of cooking devices.

[0006] To achieve the above objectives, this utility model provides a cooking device, comprising:

[0007] A coil reel, comprising a coil frame, a first coil, and a second coil, wherein the upper surface of the coil frame forms a cavity, the first coil is disposed on the inner bottom wall of the cavity, and the second coil is disposed on the inner side wall of the cavity;

[0008] A panel located above the coil disk, the panel including a first support portion and an arched portion connected to the edge of the first support portion, the arched portion arching away from the coil disk to form a cavity within the arched portion, the first support portion being located above the bottom wall of the cavity, the side wall of the cavity and the second coil extending into the cavity.

[0009] This utility model provides a cooking device in which a first coil is disposed on the inner bottom wall of a concave cavity, a second coil is disposed on the inner side wall of the concave cavity, and the panel includes a first support portion and an arched portion connected to the edge of the first support portion. The first support portion is located on the upper side of the bottom wall of the concave cavity, and the side wall of the concave cavity and the second coil extend into the convex cavity. This allows small-sized pots to be placed on the first support portion and heated by the first coil, while larger-sized pots can be placed on the arched portion and heated by the second coil. The bottom wall of the concave-bottomed pot is placed on the first support portion and heated by the first coil, while the side wall of the concave-bottomed pot is heated by the second coil. This improves the compatibility of the cooking device with pots and ensures heating performance for flat-bottomed frying pans, flat-bottomed saucepans of various sizes, and steamers. Furthermore, since the sidewalls of the concave cavity and the second coil extend into the convex cavity, not only is the distance between the second coil and the arched part reduced, but the distance between the first coil and the first support part is also reduced. This helps to shorten the distance between the coil plate and the pot, improve energy efficiency, thereby improving heating efficiency. It can also reduce the overall thickness of the cooking equipment, improve aesthetics, and enhance the convenience of the cooking equipment, making it easier to store.

[0010] In one possible implementation, along the thickness direction of the coil, the height difference H between the top surface of the second coil and the top surface of the first coil satisfies: 30mm ≥ H ≥ 5mm. This structure allows the second coil to effectively heat the sidewall of the concave-bottomed cookware without causing an excessively high heating range that would limit the use of the cookware. It also eliminates the need for an excessively high arch to meet the installation requirements of the second coil, ensuring the strength of the panel and helping to prevent the overall thickness of the cooking equipment from becoming excessive.

[0011] In one possible implementation, the inner bottom wall of the cavity has a first winding region, and the inner side wall of the cavity has a second winding region. The first coil is disposed in the first winding region, and the second coil is disposed in the second winding region. The inner diameter D2 of the second winding region satisfies: D2 ≥ 120 mm. This ensures that the second coil can generate a sufficiently large magnetic field to uniformly heat the side wall of the concave-bottomed cookware. Furthermore, considering the various sizes of cookware used, ensuring that the inner diameter D2 of the second winding region is ≥ 120 mm also accommodates a wider range of cookware sizes.

[0012] In one possible implementation, the diameter D1 of the first winding region and the inner diameter D2 of the second winding region satisfy: D2>D1≥100mm.

[0013] The diameter D1 of the first winding region is designed to be ≥100mm to ensure that the first coil generates a sufficiently strong magnetic field to effectively heat the bottom wall of the cookware, and to make the cooking equipment compatible with slightly larger flat-bottomed cookware, thus ensuring cooking results. By using D2 > D1, the second coil located in the second winding region generates a larger magnetic field to cover the side wall of the cookware, thereby improving overall energy efficiency.

[0014] In one possible implementation, both the first coil and the second coil are made of multiple strands of wire twisted together.

[0015] The ratio of the number of strands N2 of the coil winding of the second coil to the number of strands N1 of the coil winding of the first coil satisfies 5 ≥ N2 / N1 ≥ 0.2.

[0016] This structure ensures a good match between the heating effects of the first and second coils, guaranteeing that the second coil can effectively heat the side walls of concave-bottomed cookware and larger flat-bottomed cookware. In addition, when the first coil heats the bottom wall of the concave-bottomed cookware, it can prevent the second coil from heating the side walls of the concave-bottomed cookware to an excessively high temperature, thus preventing dry burning and ensuring safety in use.

[0017] In one possible implementation, the maximum number of layers T1 of the second coil along the thickness direction of the coil coil satisfies T1≥3. This ensures that the magnetic field generated by the second coil is sufficient to heat the bottom wall of larger pots and the side wall of concave pots, without causing the cooking equipment to be too thick.

[0018] In one possible implementation, the side of the arch facing the first support is a slope or an arcuate surface; and / or,

[0019] The side of each of the first coils that is away from the bottom wall of the cavity lies on the same horizontal plane.

[0020] The side of the arched portion facing the first support portion is a sloping or arc-shaped surface, which allows the arched portion to better fit the side wall of the concave-bottomed cookware. This means that the concave-bottomed cookware is more stable when placed on the cooking equipment, reducing the problem of sliding or tilting. In addition, users can place the cookware on the cooking equipment more conveniently without worrying about alignment issues, thus improving ease of use.

[0021] The side of each first coil that is away from the bottom wall of the cavity is on the same horizontal plane. This helps to ensure that the magnetic field generated by the first coil is more evenly distributed on the bottom of the cookware, improving the uniformity of heating and avoiding localized overheating or underheating.

[0022] In one possible implementation, the coil also includes a magnetic strip assembly disposed on the lower surface of the coil holder. The magnetic strip assembly is used to concentrate the magnetic lines of force generated by the first and second coils, thereby increasing the magnetic field strength and improving heating efficiency.

[0023] In one possible implementation, the cooking device further includes a control board to which the first coil and the second coil are electrically connected, and the control board controls the first coil and the second coil respectively. This helps to save energy and improve the flexibility of use.

[0024] This utility model also provides a cooking kit, including a cooking container and the aforementioned cooking equipment.

[0025] The cooking equipment and cooking kit provided by this utility model improves the compatibility of the cooking equipment with cookware, ensures the heating performance of flat-bottomed woks, flat-bottomed saucepans of various sizes and steamers, can also reduce the overall thickness of the cooking equipment, improve its aesthetics, and make the cooking equipment more convenient and easier to store.

[0064] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0065] To enable the use of round-bottomed cookware on induction cooktops, concave-bottomed induction cooktops were developed, allowing the bottom and sides of concave-bottomed cookware to be heated better, resulting in more even and efficient cooking.

[0066] However, traditional concave induction cookers have poor heating performance for flat-bottomed woks and saucepans of various sizes, or even cannot heat them at all. This is because when a flat-bottomed pan is placed in the heating area, the bottom of the pan is too far from the coil of the induction cooker, which prevents the magnetic field from effectively heating the bottom of the pan.

[0067] In view of this, the present invention provides a cooking device that improves the structure of the coil and the panel, allowing small pots to be placed on the first support part of the panel and heated by the first coil, while larger pots can be placed on the arched part of the panel and heated by the second coil. The bottom wall of the concave-bottomed pot is placed on the first support part and heated by the first coil, while the side wall of the concave-bottomed pot is heated by the second coil. This improves the compatibility of the cooking device with different types of pots and ensures heating performance for flat-bottomed frying pans and flat-bottomed saucepans of various sizes.

[0068] The cooking equipment and cooking set provided in the embodiments of this utility model are described below with reference to the accompanying drawings.

[0069] refer to Figure 1and Figure 2 As shown, this embodiment of the utility model provides a cooking device, including: a coil plate 10 and a panel 20, see reference. Figure 3 and Figure 4 As shown, the coil 10 includes a coil frame 11, a first coil 12 and a second coil 13. The upper surface of the coil frame 11 forms a cavity 111. The first coil 12 is disposed on the inner bottom wall of the cavity 111 and the second coil 13 is disposed on the inner side wall of the cavity 111.

[0070] refer to Figure 2 and Figure 3 As shown, panel 20 is located on the upper side of coil disk 10. Panel 20 includes a first support portion 21 and an arched portion 22 connected to the edge of the first support portion 21. The arched portion 22 arches away from the coil disk 10 to form a cavity 221 in the arched portion 22. The first support portion 21 is located on the upper side of the bottom wall of cavity 111. The side wall of cavity 111 and the second coil 13 extend into cavity 221.

[0071] The present invention provides a cooking device in which a first coil 12 is disposed on the inner bottom wall of a concave cavity 111, and a second coil 13 is disposed on the inner side wall of a concave cavity 111. The panel 20 includes a first support portion 21 and an arched portion 22 connected to the edge of the first support portion 21. The first support portion 21 is located on the upper side of the bottom wall of the concave cavity 111. The side wall of the concave cavity 111 and the second coil 13 extend into the convex cavity 221, so that small-sized pots can be placed on the first support portion 21 and heated by the first coil 12, while larger-sized pots can be placed on the arched portion 22 and heated by the second coil 13. The bottom wall of the concave-bottomed pot is placed on the first support portion 21 and heated by the first coil 12, and the side wall of the concave-bottomed pot is heated by the second coil 13. This improves the compatibility of the cooking device with pots and ensures heating performance for flat-bottomed frying pans, flat-bottomed saucepans of various sizes, and steamers.

[0072] Furthermore, since the sidewall of the concave cavity 111 and the second coil 13 extend into the convex cavity 221, not only is the distance between the second coil 13 and the arched portion 22 reduced, but the distance between the first coil 12 and the first support portion 21 is also reduced. This helps to shorten the distance between the coil plate 10 and the cookware, improve energy efficiency, and thus improve heating efficiency. Compared with traditional concave induction cookers, it can also reduce the overall thickness of the cooking equipment, improve aesthetics, and enhance the convenience of the cooking equipment, making it easier to store.

[0073] In use, at least one of the first coil 12 and the second coil 13 generates a high-frequency alternating electromagnetic field, causing eddy currents to be generated at the bottom of the cookware placed in the magnetic field, thereby achieving electromagnetic heating. The first coil 12 is mainly used to heat the bottom of concave-bottomed cookware and smaller-sized cookware, while the second coil 13 is mainly used to heat the side walls of concave-bottomed cookware and larger-sized cookware, improving cookware compatibility.

[0074] refer to Figure 2 and Figure 5 As shown, smaller pots can be placed on the first support 21 and fully supported by it, while the first coil 12 primarily heats them; Reference Figure 2 and Figure 6 As shown, larger pots can be placed on and supported by the arched portion 22, and the second coil 13 mainly heats them; Reference Figure 2 , Figure 7 and Figure 8 As shown, for concave-bottomed cookware such as a wok, the first coil 12 mainly heats the bottom wall of the concave-bottomed cookware, and the second coil 13 is mainly used to heat the side wall of the concave-bottomed cookware, realizing multi-directional heating, improving heating efficiency and uniformity, so that the cooking device provided by this utility model can be compatible with flat-bottomed pans of various sizes and concave-bottomed cookware such as woks, and can heat the pot wall of the concave-bottomed cookware.

[0075] refer to Figure 3 and Figure 4 As shown, the coil frame 11 is used to wind the first coil 12, the second coil 13 and install the magnetic strip assembly 14. When the coil is working, the first coil 12 and the second coil 13 generate a high-frequency alternating electromagnetic field, which causes eddy currents to be generated in the pot placed on the panel 20 to achieve electromagnetic heating.

[0076] In one possible implementation method, refer to Figure 1 and Figure 2 As shown, the first support portion 21 and the arched portion 22 can be integrally formed. That is, the first support portion 21 and the arched portion 22 are integrally formed during the manufacturing process, reducing the complexity of the splicing process.

[0077] In one possible implementation, the first support portion 21 may be a circular flat plate, and the arched portion 22 may be a ring of raised structures connected to the edge of the first support portion 21.

[0078] In one possible implementation, panel 20 further includes a second support portion 23, which may be integrally connected to the outer edge of arch 22, and the second support portion 23 may be flat.

[0079] In one possible implementation, panel 20 is, but is not limited to, a microcrystalline panel. Microcrystalline panels have good heat resistance, chemical resistance, and are easy to clean, and can also effectively conduct heat, improving heating efficiency.

[0080] In one possible implementation method, refer to Figure 9 and Figure 10 As shown, along the thickness direction of the coil disk 10, the height difference H between the top surface of the second coil 13 and the top surface of the first coil 12 satisfies: 30mm ≥ H ≥ 5mm. The top surface of the second coil 13 is the side of the second coil 13 away from the cavity 111, and the top surface of the first coil 12 is the side of the first coil 12 away from the cavity 111.

[0081] If the height difference H < 5mm, the distance between the first coil 12 and the second coil 13 will be insufficient to generate a sufficiently strong and uniform magnetic field to effectively cover the side and bottom walls of the concave-bottomed cookware. This will prevent effective heating of the side walls, severely weakening the heating effect and reducing energy efficiency. Conversely, if the height difference H > 30mm, the heating range of the cookware's side walls will be too high. This will reduce the range of applicable cookware and require a corresponding increase in the height of the arched portion 22 of the panel 20 to deepen the cavity 221 and meet the installation requirements of the second coil 13, which will affect the strength of the panel 20.

[0082] Therefore, by designing 30mm≥H≥5mm, this application enables the second coil 13 to effectively heat the side wall of the concave-bottomed cookware without causing the heating height of the side wall of the cookware to be too high, thus limiting the use of the cookware. It also eliminates the need for the arch height of the arched part 22 to be too high to meet the installation requirements of the second coil 13, ensuring the strength of the panel 20 and helping to prevent the overall thickness of the cooking equipment from being too thick.

[0083] In one possible implementation, the height difference H between the top surface of the second coil 13 and the top surface of the first coil 12 can be, for example, 5mm, 5.5mm, 6mm, 6.5mm, 7mm, 7.5mm, 8mm, 8.5mm, 9mm or 10mm.

[0084] In one possible implementation method, refer to Figure 9 and Figure 10 As shown, the inner bottom wall of the cavity 111 has a first winding area 112, and the inner side wall of the cavity 111 has a second winding area 113. The first coil 12 is disposed in the first winding area 112, and the second coil 13 is disposed in the second winding area 113. The inner diameter D2 of the second winding area 113 satisfies: D2≥120mm.

[0085] The design of D2 ≥ 120mm is to prevent the second coil 13 from failing to effectively cover the side wall area of ​​the concave-bottomed cookware, thus ensuring effective heating of the side wall and affecting the heating effect. Therefore, in this embodiment, by ensuring D2 ≥ 120mm, it is guaranteed that the second coil 13 can generate a sufficiently large magnetic field to uniformly heat the side wall of the concave-bottomed cookware. Furthermore, considering the various sizes of cookware used, ensuring that the inner diameter D2 of the second winding area 113 is ≥ 120mm can also accommodate a wider range of cookware sizes.

[0086] The first winding area 112 has a plurality of first partition ribs spaced apart along the radial direction of the coil frame 11. Each first partition rib includes a plurality of first winding rib segments 1121 spaced apart along the circumferential direction of the coil frame 11, thereby defining a plurality of first winding grooves 1122 spaced apart along the radial direction of the coil frame 11 on the coil frame 11. The first coil 12 is correspondingly arranged in the first winding grooves 1122.

[0087] The second winding area 113 has a plurality of second ribs spaced apart along the radial direction of the coil frame 11. Each second rib includes a plurality of second winding rib segments 1131 spaced apart along the circumferential direction of the coil frame 11, thereby defining a plurality of second winding grooves 1132 spaced apart along the radial direction of the coil frame 11 on the coil frame 11. The second coil 13 is correspondingly arranged in the second winding grooves 1132.

[0088] In one possible implementation, the diameter D1 of the first winding region 112 and the inner diameter D2 of the second winding region 113 satisfy: D2>D1≥100mm.

[0089] Since the first coil 12 is located in the first winding area 112, its main function is to heat the bottom of the cookware. The diameter D1 of the first winding area 112 is designed to be ≥100mm to ensure that the first coil 12 generates a sufficiently strong magnetic field to effectively heat the bottom wall of the cookware, and to allow the cooking equipment to be compatible with slightly larger flat-bottomed cookware, thus guaranteeing cooking results. By designing D2 > D1, the second coil 13, located in the second winding area 113, generates a larger magnetic field to cover the side wall of the cookware, thereby improving overall energy efficiency.

[0090] In one possible implementation, both the first coil 12 and the second coil 13 are made of multiple single-strand wires twisted together. Twisting multiple single-strand wires can increase the total conductive cross-sectional area of ​​the coil, thereby improving the conductivity of the coil, helping to reduce resistance loss and improve energy efficiency. Furthermore, the twisted structure is generally more flexible and mechanically stronger than a single thick wire, which makes the coil more durable during manufacturing and installation, reducing the problem of breakage.

[0091] In one possible implementation, the ratio of the number of strands N2 of the coil winding of the second coil 13 to the number of strands N1 of the coil winding of the first coil 12 satisfies 5 ≥ N2 / N1 ≥ 0.2.

[0092] If N2 / N1 < 0.2, it means that the second coil 13 has too little winding, resulting in a weak magnetic field. Insufficient magnetic field strength leads to low heating efficiency, making it difficult to heat large flat-bottomed pans and affecting the heating effect on the side walls of concave-bottomed pans. If N2 / N1 > 5, it means that the second coil 13 has too much winding, resulting in a strong magnetic field. When heating concave-bottomed pans, this can easily cause insufficient heat at the bottom and excessive heat on the side walls, leading to dry-burning of the side walls and affecting normal use.

[0093] In this application, by designing 5≥N2 / N1≥0.2, the heating effects of the first coil 12 and the second coil 13 are well matched, ensuring that the second coil 13 can effectively heat the side wall of the concave bottom pot and the larger flat bottom pot. In addition, when the first coil 12 heats the bottom wall of the concave bottom pot, it can also prevent the heating temperature of the second coil 13 on the side wall of the concave bottom pot from being too high, causing the problem of dry burning, thus ensuring the safety of use.

[0094] In one possible implementation, N2 / N1 can be, for example, 0.2, 0.5, 1, 1.5, 2, 3, 3.5, 4, 4.5, or 5, etc.

[0095] In one possible implementation, the number of second coils 13 is greater than one along the radial direction of the coil disk 10. For example, the number of second coils 13 can be two, four, five, etc.

[0096] In one possible implementation, the maximum number of layers T1 of the second coil 13 along the thickness direction of the coil disk 10 satisfies T1≥3. The number of layers of the second coil 13 is an important factor affecting the magnetic field distribution and heating effect generated by the second coil 13. Increasing the maximum number of layers T1 of the second coil 13 can enhance the magnetic field strength generated by the second coil 13, thereby improving the heating efficiency, which is especially important for flat-bottomed cookware that requires rapid heating or heating a large area.

[0097] In one possible implementation, the maximum number of layers T1 of the second coil 13 along the thickness direction of the coil disk 10 can be, for example, 3, 4, 5 or 6.

[0098] In this example, four second coils 13 are arranged radially along the coil disk 10. From the center to the edge of the coil disk 10, the four second coils 13 are arranged in 1, 2, 3, and 3 layers respectively. This ensures that the magnetic field generated by the second coils 13 can meet the requirements for heating the bottom wall of larger pots and the side wall of concave-bottomed pots, without causing the cooking equipment to be too thick. The maximum number of layers T1 of the second coils 13 is located near the edge of the coil disk 10.

[0099] In one possible implementation, the second coil 13 can be arranged in 1, 2, 3 or 4 layers along the thickness direction of the coil disk 10.

[0100] In other possible implementations, the number of layers of each first coil 12 can be inconsistent along the thickness direction of the coil disk 10. By adjusting the number of layers of the first coil 12, the magnetic field can be strengthened or weakened, thereby optimizing the configuration of the first coil 12. In areas where a strong magnetic field is not needed, the number of coil layers can be reduced, which can reduce energy consumption and improve the overall energy efficiency of the cooking equipment.

[0101] In one possible implementation method, refer to Figure 1 , Figure 2 and Figure 3 As shown, the first support part 21 is flat; this structure allows smaller pots to be placed stably on the first support part 21 and supported by it.

[0102] In one possible implementation, the side of the arched portion 22 facing the first support portion 21 is a sloped or curved surface, which allows the arched portion 22 to better fit against the side wall of the concave-bottomed cookware. This means that the concave-bottomed cookware is more stable when placed on the cooking equipment, reducing the problem of sliding or tilting. In addition, users can place the cookware on the cooking equipment more conveniently without worrying about alignment issues, thus improving ease of use.

[0103] In one possible implementation, the side of each first coil 12 away from the bottom wall of the cavity 111 is on the same horizontal plane. This helps ensure a more uniform distribution of the magnetic field generated by the first coil 12 on the bottom of the cookware, improving heating uniformity and avoiding localized overheating or underheating.

[0104] In one possible implementation method, refer to Figure 4 and Figure 10As shown, the coil 10 also includes a magnetic strip assembly 14, which is disposed on the lower surface of the coil frame 11, i.e., the side of the coil frame 11 facing away from the first coil 12. The magnetic strip assembly 14 has good magnetic conductivity and is used to concentrate the magnetic lines of force generated by the first coil 12 and the second coil 13, thereby increasing the magnetic field strength and improving the heating efficiency.

[0105] The magnetic strip assembly 14 includes a first magnetic strip 141 and a second magnetic strip 142. The first magnetic strip 141 is located below the first winding area 112 and extends radially along the coil frame 11. One end of the first magnetic strip 141 extends to the center of the coil frame 11, and the other end extends to the edge of the bottom wall of the coil frame 11. Multiple first magnetic strips 141 can be arranged at circumferential intervals along the coil frame 11. The first magnetic strips 141 can reduce the diffusion and loss of the magnetic field generated by the first coil 12, ensuring that more magnetic lines of force are concentrated on the bottom of the cookware, thus improving energy utilization.

[0106] The second magnetic strip 142 is located below the second winding region 113. Multiple second magnetic strips 142 can be arranged at intervals along the circumference of the coil frame 11. The second magnetic strips 142 can reduce the diffusion and loss of the magnetic field generated by the second coil 13, enhance the magnetic field strength, which means faster heating speed and higher energy conversion efficiency, thus improving energy utilization.

[0107] In one possible implementation method, refer to Figure 2 and Figure 3 As shown, the cooking device also includes a control board 50, and the first coil 12 and the second coil 13 are electrically connected to the control board 50 respectively. The control board 50 controls the first coil 12 and the second coil 13 respectively.

[0108] The control panel 50 independently controls the first coil 12 and the second coil 13, enabling the cooking device to support multiple cooking modes. This allows for easy control of the operation of the first coil 12 and the second coil 13 depending on the type of cookware used, helping to save energy and ensure effective heating.

[0109] For example, when using a concave-bottomed cookware, the control board 50 can control the first coil 12 and the second coil 13 to work simultaneously and reasonably allocate the power of the first coil 12 and the second coil 13. The first coil 12 mainly heats the bottom wall of the concave-bottomed cookware, and the second coil 13 mainly heats the side wall of the concave-bottomed cookware, so that the concave-bottomed cookware is heated more evenly and the cooking effect is improved.

[0110] When using smaller cookware, the control board 50 can energize the first coil 12 and de-energize the second coil 13, thus preventing the second coil 13 from operating and improving energy efficiency. Alternatively, when using larger cookware, the control board 50 can energize the second coil 13 and de-energize the first coil 12, thus preventing the first coil 12 from operating.

[0111] In one possible implementation method, refer to Figure 1 and Figure 2 As shown, the cooking device also includes a housing 30, a panel 20 which can cover the top of the housing 30 and form a cavity 31 between the housing 30 and the panel 20, a coil 10 which is disposed in the cavity 31, and heat dissipation holes are provided on the side wall of the housing 30.

[0112] In one possible implementation, the cooking equipment also includes a fan 40 and a lamp plate 60, which are disposed within the accommodating cavity 31. The fan 40 is used to accelerate the airflow speed within the accommodating cavity 31, using the airflow to carry away the heat accumulated around the lamp plate 60, control board 50, and coil 10, ensuring effective heat dissipation for the lamp plate 60, control board 50, and coil 10, thereby reducing the temperature of the lamp plate 60, control board 50, and coil 10 and preventing excessively high temperatures during operation, which could affect the normal operation of the induction cooker.

[0113] This utility model embodiment also provides a cooking kit, including a cooking container 70 and the cooking equipment described above.

[0114] In one possible implementation, the cooking container 70 includes, but is not limited to, a saucepan, a wok, a steamer, a kettle, etc.

[0115] In one possible implementation, the aforementioned cooking equipment includes an induction cooker.
