[0022] Reference Figure 1An impact-resistant structure includes: a furnace body 100, an electric heating element 700, and a protective cover 500; the electric heating element 700 is disposed inside the furnace body 100 and is used for heating; a panel 200 is installed on the furnace body 100, the middle part of the panel 200 is bent toward the inside of the furnace body 100 and forms an inner spherical concave surface for supporting cookware; the protective cover 500 is disposed on the panel 200, the protective cover 500 is located between the panel 200 and the electric heating element 700, the protective cover 500 is able to support the panel 200 when it sinks, and the protective cover 500 is configured to be insulated. This impact-resistant structure, through the installation of an insulating protective cover 500, can promptly support the panel 200 when it is impacted and dented, effectively preventing the panel 200 from contacting live parts such as the heating element 700. This greatly enhances the safety of the induction cooker and avoids dangerous situations such as leakage and short circuits caused by panel 200 breakage. It also provides additional protection for the heating element 700, reduces maintenance costs, extends the service life of the induction cooker, and improves product reliability and market competitiveness.

[0023] Specifically, the protective cover 500 can be made of high-strength, high-temperature-resistant special engineering plastics, such as polyphenylene sulfide or polyetheretherketone, to ensure that it maintains good mechanical and insulation properties even under the high-temperature operating environment of the induction cooker. The shape of the protective cover 500 matches the inner spherical concave surface of the panel 200. Through precise molding, it is made to fit tightly against the panel 200, which can fully support the panel 200 while reducing the gap between the two and improving the overall stability. In addition, the edges of the protective cover 500 can be designed with a slightly upturned structure to further enhance its protective effect on the edges of the panel 200 and prevent the edges of the panel 200 from being damaged by bumps and knocks.

[0024] In some embodiments, reference is made to Figure 3 The protective cover 500 is recessed, with the same concave depth as the panel 200. This recessed design, matching the panel 200's concavity, creates a uniform support surface between the two surfaces. This more evenly distributes impact forces on the panel 200, enhancing its protection and reducing the risk of damage caused by localized stress concentration. Furthermore, the identical concavity also optimizes the internal space layout of the induction cooker, improving space utilization and resulting in a more compact and aesthetically pleasing overall structure, enhancing the product's perceived quality and user experience.

[0025] It is foreseeable that, in practical implementation, the concave depth of the protective cover 500 can be precisely designed according to the different sizes and depths of the panel 200. For example, for high-power, large-size concave induction cookers, the concave depth of the protective cover 500 can be appropriately increased to better match the shape of the panel 200 and enhance the support effect. At the same time, the inner surface of the protective cover 500 can be specially textured, such as by adding some tiny protrusions or grooves, to enhance the friction between it and the panel 200, prevent the panel 200 from shifting due to vibration or other reasons during use, and further improve the stability of the structure.

[0026] In some embodiments, reference is made to Figure 2 A temperature sensor 300 is located in the center of the protective cover 500. This temperature sensor 300 contacts the panel 200 and is used to detect the temperature. By placing the temperature sensor 300 in the center of the protective cover 500 and ensuring its contact with the panel 200, the temperature changes of the panel 200 can be detected in real time and accurately. Compared to traditional temperature detection methods, this design more directly reflects the actual temperature of the heating area, providing a more precise basis for the temperature control of the induction cooker. This results in more accurate cooking temperature adjustment, improving cooking effects and food quality.

[0027] It is foreseeable that the temperature sensing device 300 can employ high-precision thermistors or infrared temperature sensors. Taking a thermistor as an example, it is installed in a specially designed mounting slot in the middle of the protective cover 500, and makes good contact with the panel 200 through materials such as thermally conductive silicone grease, ensuring the accuracy and sensitivity of temperature transmission. Simultaneously, to protect the temperature sensing device 300 from electromagnetic interference and mechanical damage, a high-temperature resistant and electromagnetic interference-resistant protective sleeve, such as one made of ceramic fiber, can be placed over it.

[0028] In some embodiments, reference is made to Figure 2 The furnace body 100 is equipped with an on / off circuit. The temperature sensing device 300 and the heating element 700 are both electrically connected to this circuit. The on / off circuit controls the opening and closing of the heating element 700 based on the electrical signal transmitted from the temperature sensing device 300. This design achieves automated and intelligent control of the induction cooker to shut off heating when it overheats, improving cooking efficiency and convenience, enhancing cooking quality and user experience, further strengthening product safety and reliability, and extending the lifespan of the induction cooker.

[0029] In some embodiments, reference is made to Figure 3A snap-fit ​​structure 550 is provided between the protective cover 500 and the heating element 700, securing them together. This snap-fit ​​structure offers advantages such as simple structure, convenient installation, and a strong connection. Compared to traditional screw or adhesive connections, the snap-fit ​​structure 550 eliminates the need for additional connectors, reducing the number of parts and assembly steps, lowering production costs and assembly difficulty, and improving production efficiency. Simultaneously, the snap-fit ​​structure 550 ensures a tight fit between the protective cover 500 and the heating element 700, guaranteeing good electrical insulation and heat transfer, preventing problems such as poor contact and uneven heating caused by loose connections, improving the heating efficiency and safety of the induction cooker, and facilitating subsequent maintenance and replacement.

[0030] In some embodiments, reference is made to Figure 3 The heating element 700 includes a coil 750, with the coil 750 and panel 200 located on opposite sides of a protective cover 500. The protective cover 500 and the coil 750 are fixed together by a snap-fit ​​structure 550. This layout is reasonable and helps optimize the electromagnetic field distribution inside the induction cooker, improving the efficiency of electromagnetic induction heating. The protective cover 500, located between the coil 750 and panel 200, effectively isolates the high temperature and electromagnetic field generated by the coil 750, reducing its impact on the panel 200, and also provides some protection for the coil 750, preventing direct damage to the coil 750 when the panel 200 is subjected to impact. The snap-fit ​​structure 550 ensures a tight connection between the coil 750 and the protective cover 500, guaranteeing the stability and reliability of the induction cooker during operation. It also facilitates the disassembly and maintenance of the coil 750, reducing maintenance costs and difficulty.

[0031] It is foreseeable that, in practical applications, the coil 750 can be made of high-performance magnetic materials, such as silicon steel sheets or ferrite materials, to improve its magnetic permeability and electromagnetic induction efficiency. The shape and size of the coil 750 should match the shapes of the protective cover 500 and the panel 200 to ensure that the electromagnetic field can act evenly on the cookware on the panel 200. Simultaneously, the winding process and wire diameter selection of the coil 750 are also crucial and should be optimized according to the power requirements of the induction cooker to achieve the best heating effect. Furthermore, to improve the heat dissipation performance of the coil 750, cooling fans or heat sinks can be installed around it to dissipate the heat generated during operation, extend its service life, and ensure the long-term stable operation of the induction cooker.

[0032] In some embodiments, reference is made to Figure 4 The snap-fit ​​structure 550 includes a snap hook 552, which is disposed on one of the protective cover 500 and the coil disc 750 and snaps onto the other. The snap-fit ​​structure 550 with snap hook 552 is simple, practical, and easy to manufacture and assemble. The snap hook 552 connection method not only allows for quick fixation of the protective cover 500 and the coil disc 750, but also ensures good electrical insulation between them, avoiding electrical faults caused by poor contact. It also facilitates quick disassembly when needed, making it convenient for maintenance and repair of the induction cooker's internal components, reducing maintenance costs and time, and improving product maintainability and user satisfaction.

[0033] Specifically, the hook 552 can be made of a plastic or metal material with a certain degree of elasticity, such as nylon or stainless steel. For plastic hooks 552, their surface can be reinforced, such as by adding reinforcing materials like glass fiber, to improve their strength and wear resistance. During installation, the hook 552 can be fixed to the protective cover 500 or the coil disc 750 by ultrasonic welding or by hook 552 method to ensure a firm connection.

[0034] In some embodiments, reference is made to Figure 3 Multiple hooks 552 are provided, each positioned along the edge of the protective cover 500 and distributed around its center. This distribution around the center ensures a more uniform and secure connection between the protective cover 500 and the coil 750, preventing issues such as loosening or deformation of the protective cover 500 due to uneven stress on individual hooks 552. The multiple hooks 552 distributed around the center provide effective support and fixation for the protective cover 500 in all directions, enhancing structural stability and reliability, and improving the safety of the induction cooker during use. Furthermore, this surrounding hook layout optimizes internal space utilization, resulting in a more compact and rational arrangement of components, reducing the overall size of the induction cooker, and facilitating storage and use for the user.

[0035] It is foreseeable that, in the specific design, the number and spacing of the hooks 552 can be reasonably determined according to the size and shape of the protective cover 500. For example, for a larger protective cover 500, the number of hooks 552 can be appropriately increased to ensure the firmness of the connection. At the same time, the distribution of the hooks 552 should be as uniform as possible to ensure even distribution of force on the protective cover 500. Furthermore, to improve the connection strength of the hooks 552, reinforcing ribs can be set at the edges of the protective cover 500 to enhance the structural strength of the edges and prevent damage to the edges of the protective cover 500 due to excessive force on the hooks 552. During installation, specialized installation tools can be used to assist in the accurate docking and fixing of the hooks 552 with the slots on the coil disc 750, improving assembly efficiency and quality.

[0036] In some embodiments, reference is made to Figure 2 The protective cover 500 is an insulated plastic cover. Made of insulating plastic, the protective cover 500 possesses excellent electrical and mechanical insulation properties, effectively preventing safety accidents caused by contact between the panel 200 and live parts after the panel 200 breaks, thus ensuring user safety. The plastic protective cover 500 also offers advantages such as light weight, low cost, and ease of molding and processing, helping to reduce the production cost and weight of the induction cooker, improving its cost-effectiveness and market competitiveness. Furthermore, the plastic protective cover 500 has good corrosion resistance and anti-aging properties, maintaining good performance during long-term use of the induction cooker, extending its lifespan, reducing maintenance and replacement frequency, and providing users with a more convenient and economical user experience.

[0037] The second aspect of this utility model provides an embodiment of an induction cooker, including the aforementioned impact-resistant structure. This induction cooker, employing the aforementioned impact-resistant structure, possesses the advantages of enhanced safety, precise temperature control, intelligent cooking functions, and convenient installation and maintenance. While meeting users' daily cooking needs, this induction cooker effectively reduces usage risks, providing users with a healthier, safer, and more efficient cooking experience.

[0038] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
