Abstract
Description
Technical Field
[0001] This utility model relates to the field of induction cooker technology, specifically to an induction cooker coil. Background Technology
[0002] The induction cooker coil is one of the core components of an induction cooker. Its main function is to generate eddy currents through electromagnetic induction, thereby heating the cookware. The design and materials of the coil directly affect the heating efficiency and lifespan of the induction cooker. The coil is typically constructed from a high-temperature resistant, flame-retardant plastic frame, filled with magnetic oxide powder to enhance its magnetic conductivity. Copper or aluminum is generally used as the conductive material. Copper coils offer better thermal and magnetic conductivity, and also exhibit superior corrosion resistance and high-temperature resistance compared to aluminum coils. Coil coils are usually designed with a double-layer structure. This design increases the heating area and uniformity, reducing the possibility of localized overheating. A coil diameter of 200mm or more is generally recommended, with each coil having a diameter of at least 0.35mm. A larger diameter increases the heating area, resulting in more even heat distribution. Double-layer coils are more durable and provide more stable heating than single-layer coils; therefore, their use is recommended.
[0003] In existing technologies, traditional induction cookers suffer from localized or uneven heating during use. This not only affects the cooking results but may also cause localized overheating of the pot bottom, damaging the cookware or wasting energy. Furthermore, most induction cookers are designed to heat only a single pot bottom, making it difficult to meet users' needs for multiple cooking methods on the same device. Usually, two induction cookers are needed, which not only takes up more space but also increases operational complexity. In addition, using two devices simultaneously significantly increases operating costs and energy consumption, failing to meet modern users' demands for efficient, economical, and multifunctional kitchen appliances. Utility Model Content
[0004] Based on this, the purpose of this utility model is to provide an induction cooker coil to solve the technical problem that most induction cookers are designed to heat only a single pot bottom, making it difficult to meet the user's needs for multiple cooking methods on the same device.
[0005] To achieve the above objectives, the present invention provides the following technical solution: an induction cooker coil, including a housing, wherein multiple sets of first mounting plates are fixedly connected inside the housing, multiple sets of fixing blocks are fixedly connected to the top of the first mounting plates, an outer ring is fixedly connected inside the housing, multiple sets of second mounting plates are fixedly connected inside the housing, the second mounting plates are located inside the outer ring, and an inner ring is fixedly connected at the center of the inner side of the outer ring.
[0006] By adopting the above technical solution, fixing the fixing blocks to the top of the first mounting plate and the second mounting plate respectively, and then evenly winding the two sets of coils on the outer and inner sides of the outer ring respectively, and fixing the position of the coils by fixing the fixing blocks, and passing through the first through slot at one end of the inner ring, the coil on the outer side of the inner ring can be wound in multiple layers on the inner side of the inner ring, thereby achieving the effect of strengthening the heating at the center of the induction cooker. Passing through the second through slot at one side of the outer ring, the coil on the inner side of the outer ring can be passed through the second through slot, which connects the coil to the external control device. At the same time, the external power supply is connected to the coil on the inner side of the outer ring through the fourth through slot. Passing through the third through slot at one side of the casing, the coil on the outer side of the outer ring can be electrically connected to the external power supply, thereby achieving the effect of heating the inner and outer sides of the outer ring separately, and achieving energy saving.
[0007] Furthermore, the bottom end of the inner ring is fixedly connected to the top end of the inner side of the housing, and a first through groove is provided on one side of the inner ring.
[0008] By adopting the above technical solution, the first through groove is set at one end of the inner ring, allowing one end of the outer coil of the inner ring to pass through the first through groove, thereby enabling multi-layer winding on the inner side of the inner ring. This design significantly enhances the heating effect in the central area of the induction cooker, ensuring that the food is heated evenly in the center.
[0009] Furthermore, a second through groove is provided on one side of the outer ring, and the second through groove is on the same side as the first through groove.
[0010] By adopting the above technical solution, one end of the inner coil of the outer ring is made to pass through the second through slot on one side of the outer ring, thereby realizing the connection between the coil and the external control device and ensuring the controllability and flexibility of the heating function.
[0011] Furthermore, a third through slot is provided on one side of the housing, and a first threading plate is fixedly connected to one side of the housing.
[0012] By adopting the above technical solution, one end of the outer ring coil passes through the third through slot on one side of the housing, thereby realizing the electrical connection between the outer ring coil and the external power supply. This design not only supports separate heating of the inner and outer sides of the outer ring, but also effectively avoids the overlap and interference of heating areas.
[0013] Furthermore, a fourth through slot is provided on the other side of the housing, and a second threading plate is fixedly connected to one end near the fourth through slot.
[0014] By adopting the above technical solution, an external power source is connected to the coil inside the outer ring through the fourth channel, providing a stable power supply to support the independent heating operation of the inner and outer rings.
[0015] Furthermore, the first mounting plate is distributed in a ring on the outer side of the outer ring, and the second mounting plate is distributed in a ring on the inner side of the outer ring, with the first mounting plate and the second mounting plate not in contact.
[0016] By adopting the above technical solution, through precise through-slot design and coil configuration, it is possible to achieve centralized heating in the inner ring area according to user needs, while achieving auxiliary heating or independent heating in the outer ring area, providing users with flexible and diverse cooking options.
[0017] In summary, this utility model has the following beneficial effects: By fixing the fixing blocks to the tops of the first and second mounting plates respectively, and then evenly winding two sets of coils on the outer and inner sides of the outer ring respectively, and fixing the position of the coils by the fixing blocks, the first through slot at one end of the inner ring allows one end of the coil on the outer side of the inner ring to pass through the first through slot, so that the coil can be wound in multiple layers on the inner side of the inner ring, thereby achieving the effect of strengthening the heating effect at the center of the induction cooker. The second through slot at one side of the outer ring allows one end of the coil on the inner side of the outer ring to pass through the second through slot, so that the coil can be connected to the external control device. At the same time, the external power supply is connected to the coil on the inner side of the outer ring through the fourth through slot. The third through slot at one side of the casing allows one end of the coil on the outer side of the outer ring to pass through the third through slot, so that the coil on the outer side of the outer ring is electrically connected to the external power supply, thereby achieving the effect of heating the inner and outer sides of the outer ring respectively, and achieving energy saving effect.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0024] The embodiments of this utility model will be described below based on its overall structure.
[0025] An induction cooker coil, such as Figures 1-4 As shown, the device includes a housing 1. Multiple sets of first mounting plates 2 are fixedly connected inside the housing 1. Multiple sets of fixing blocks 3 are fixedly connected to the top of the first mounting plates 2. An outer ring 4 is fixedly connected inside the housing 1. Multiple sets of second mounting plates 5 are fixedly connected inside the housing 1. The second mounting plates 5 are located inside the outer ring 4. An inner ring 6 is fixedly connected to the center of the inner side of the outer ring 4. Specifically, during installation, the fixing blocks 3 are first fixed to the top of the first mounting plates 2 and the second mounting plates 5 respectively to ensure that the installation structure of the coil is stable and reliable. Then, the two sets of coils are evenly wound around the outer and inner sides of the outer ring 4 respectively. At the same time, the fixing blocks 3 are used to accurately fix the position of the coils to prevent the coils from shifting during use.
[0026] Please see Figure 1 and Figure 2 The bottom end of the inner ring 6 is fixedly connected to the top of the inner side of the casing 1. A first through groove 7 is provided on one side of the inner ring 6. Specifically, through the first through groove 7 provided at one end of the inner ring 6, one end of the outer coil of the inner ring 6 passes through the first through groove 7, so that multiple layers of winding can be achieved on the inner side of the inner ring 6. This design significantly enhances the heating effect of the central area of the induction cooker and ensures that the food is heated evenly in the center.
[0027] Please see Figure 1 and Figure 3 A second through groove 8 is provided on one side of the outer ring 4. The second through groove 8 is on the same side as the first through groove 7. Specifically, through the second through groove 8 provided on one side of the outer ring 4, one end of the inner coil of the outer ring 4 passes through the second through groove 8, thereby realizing the connection between the coil and the external control device and ensuring the controllability and flexibility of the heating function.
[0028] Please see Figure 1 and Figure 4 A third through slot 9 is provided on one side of the housing 1, and a first wire guide plate 10 is fixedly connected to one side of the housing 1. Specifically, through the third through slot 9 provided on one side of the housing 1, one end of the outer coil of the outer ring 4 passes through the third through slot 9, thereby realizing the electrical connection between the outer coil of the outer ring 4 and the external power supply. This design not only supports the separate heating of the inner side and the outer side of the outer ring 4, but also effectively avoids the overlap and interference of the heating areas.
[0029] Please see Figure 1On the other side of the housing 1, a fourth through slot 11 is provided. A second wire guide plate 12 is fixedly connected to one end of the fourth through slot 11. Specifically, the external power supply is connected to the coil inside the outer ring 4 through the fourth through slot 11 to provide a stable power supply to support the independent heating operation of the inner ring 6 and the outer ring 4.
[0030] Please see Figure 1 The first mounting plate 2 is distributed in a ring on the outer side of the outer ring 4, and the second mounting plate 5 is distributed in a ring on the inner side of the outer ring 4. The first mounting plate 2 and the second mounting plate 5 do not contact each other. Specifically, through precise through-slot design and coil configuration, it is possible to achieve centralized heating in the inner ring 6 area according to user needs, while achieving auxiliary heating or independent heating in the outer ring 4 area, providing users with flexible and diverse cooking options.
[0031] The working principle of this utility model is as follows: When using it, during the installation work, first fix the fixing block 3 to the top of the first mounting plate 2 and the second mounting plate 5 respectively to ensure that the installation structure of the coil is stable and reliable. Then, the two sets of coils are evenly wound on the outer and inner sides of the outer ring 4 respectively. At the same time, the fixing block 3 is used to accurately fix the position of the coil to prevent the coil from shifting during use.
[0032] The first through groove 7 provided at one end of the inner ring 6 allows one end of the outer coil of the inner ring 6 to pass through the first through groove 7, thereby enabling multi-layer winding on the inner side of the inner ring 6. This design significantly enhances the heating effect in the central area of the induction cooker, ensuring that the food is heated evenly in the center. In addition, the second through groove 8 provided on one side of the outer ring 4 allows one end of the inner coil of the outer ring 4 to pass through the second through groove 8, thereby enabling the connection between the coil and the external control device, ensuring the controllability and flexibility of the heating function.
[0033] Meanwhile, an external power supply is connected to the coil inside the outer ring 4 through the fourth slot 11 to provide a stable power supply to support the independent heating operation of the inner ring 6 and the outer ring 4. Through the third slot 9 set on one side of the housing 1, one end of the outer coil of the outer ring 4 passes through the third slot 9, thereby realizing the electrical connection between the outer coil of the outer ring 4 and the external power supply. This design not only supports the separate heating of the inner side and the outer side of the outer ring 4, but also effectively avoids the overlap and interference of the heating areas.
[0034] In addition, the design of the first wire guide plate 10 and the second wire guide plate 12 makes the coil arrangement more regular, and facilitates the installation and maintenance of the coil, further improving the overall reliability and maintenance convenience of the equipment.
[0035] Through precise slot design and coil configuration, the entire system can achieve centralized heating in the inner ring of 6 zones according to user needs, while providing auxiliary or independent heating in the outer ring of 4 zones. The outer and inner rings can be activated according to the size of the pot, providing users with flexible and diverse cooking options. This greatly enhances the practicality and user experience of the induction cooker, while also achieving energy-saving effects.
