Description

Technical Field

[0001] This utility model relates to the field of electromagnetic heating technology, and in particular to an electromagnetic heating coil disk of a series spiral coil array. Background Technology

[0002] Electromagnetic heating coils are the core components of induction cookers, induction stoves, and other similar appliances. They generate an alternating magnetic field by passing an alternating current through the coil, which induces eddy currents at the bottom of the cookware to achieve heating. They are widely used in home kitchens, restaurant kitchens, and other scenarios, providing efficient heat source support for cooking.

[0003] Existing electromagnetic heating coils mostly employ a single coil or a simple partitioned coil structure. A single coil is an integral planar spiral structure that achieves heating through a concentrated magnetic field in the central area; a partitioned coil divides the coil into multiple independent areas, each with a different power, which can be manually switched according to the size of the cookware.

[0004] However, existing coils are position-sensitive, and the cookware must be placed precisely in the center. If it deviates from the center, the magnetic field strength drops sharply, and the heating efficiency is greatly reduced. Traditional coils have uneven magnetic field coverage, which can easily create heating blind spots and cause uneven heating of food. To address these issues, an electromagnetic heating coil with a series spiral coil array is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an electromagnetic heating coil disk with a series spiral coil array, which aims to improve the problem of uneven heating caused by uneven magnetic field in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An electromagnetic heating coil disc of a series spiral coil array includes a support plate, a plurality of coil frame assemblies are fixedly connected to the top of the support plate, a heating component is installed inside the coil frame assembly, and a supplementary component is installed at the bottom of the support plate.

[0008] The heating assembly includes a spiral coil, which is installed inside the coil frame assembly, and multiple spiral coils are connected in series.

[0009] As a further description of the above technical solution:

[0010] The supplementary component includes a magnetic strip assembly, which is installed at the bottom of the support plate and is evenly distributed at the bottom of the support plate.

[0011] As a further description of the above technical solution:

[0012] A mounting plate is installed at the bottom of the support plate, and multiple magnetic strips are assembled and installed at the bottom of the mounting plate;

[0013] As a further description of the above technical solution:

[0014] The top of the support plate is equipped with multiple terminals, and one end of the spiral coil is fixedly connected to the middle of the terminals.

[0015] As a further description of the above technical solution:

[0016] The outer side of the terminal block is threaded with a fixing nut, and the connection end of the spiral coil is located below the fixing nut;

[0017] As a further description of the above technical solution:

[0018] The mounting plate has multiple mounting holes inside;

[0019] As a further description of the above technical solution:

[0020] An insulating mica sheet is mounted on top of the coil frame assembly, and the spiral coil is located between the insulating mica sheet and the coil frame assembly.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this invention, rapid heating is achieved by activating the spiral coils. The spiral coils are connected in series and arranged compactly, generating a continuous and uniformly distributed magnetic field. When the cookware is within the area where the spiral coils are arranged, relatively uniform heating can be obtained over a large area, thereby avoiding the problems of local overheating or insufficient heating.

[0023] 2. In this invention, during heating, the magnetic strip combination increases the inductance of the coil, thereby concentrating magnetic lines of force and reducing magnetic leakage. This not only improves energy transmission efficiency but also reduces interference to surrounding electronic equipment. Furthermore, the magnetic strip provides additional energy, further enhancing the coil's energy output. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 , Figure 3 and Figure 4 An embodiment of this utility model is provided: an electromagnetic heating coil disk of a series spiral coil array, including a support plate 2. Multiple coil frame assemblies 5 are fixedly connected to the top of the support plate 2. The coil frame assemblies 5 provide a stable mounting carrier for the spiral coils 6, ensuring that the coils are not easily displaced during operation. A heating component is installed inside the coil frame assembly 5. The heating component is the core part for realizing electromagnetic heating and generates heat through electromagnetic induction. A supplementary component is installed at the bottom of the support plate 2. The supplementary component is used to enhance the working efficiency of the heating component.

[0033] The heating assembly includes a spiral coil 6, which is installed inside the coil frame assembly 5. Multiple spiral coils 6 are connected in series, allowing current to flow sequentially through each coil. This close arrangement of the coils generates a continuous and uniformly distributed magnetic field. When the cookware is placed above this coil array, it receives relatively uniform heating over a larger area, effectively reducing localized overheating or underheating and improving heating efficiency. Multiple terminals 3 are installed on the top of the support plate 2. One end of each spiral coil 6 is fixedly connected to the middle of a terminal 3, which enables the multiple spiral coils 6 to be connected in series. The key component of the connection is the fixing of the ends of each spiral coil 6 to the terminal block 3. This ensures stable current transmission in the series circuit, guarantees that the entire coil array can work together to form a continuous magnetic field, and provides a circuit basis for uniform heating. The outer thread of the terminal block 3 is connected to a fixing nut 7. The connection end of the spiral coil 6 is located below the fixing nut 7. The fixing nut 7, through its thread engagement with the terminal block 3, can tightly press the connection end of the spiral coil 6 onto the terminal block 3, effectively preventing the coil connection end from loosening or falling off, ensuring the reliability of the circuit connection, and avoiding problems such as reduced heating efficiency or coil damage due to poor contact.

[0034] Reference Figure 1 and Figure 5 The supplementary components include magnetic strip assembly 4, which is installed at the bottom of support plate 2. The magnetic strip assembly 4 is evenly distributed at the bottom of support plate 2. The magnetic strip assembly 4 can increase the inductance of the coil. Through the even distribution, the magnetic lines of force can be more comprehensively concentrated, and the leakage magnetic phenomenon can be greatly reduced. This not only improves the energy transmission efficiency and allows electrical energy to be converted into heat energy more efficiently, but also reduces electromagnetic interference to surrounding electronic equipment. At the same time, the magnetic strip assembly 4 can also provide additional energy to the coil, further enhancing the heating energy of the coil. A mounting plate 8 is installed at the bottom of support plate 2. Multiple magnetic strip assemblies 4 are installed at the bottom of mounting plate 8. Mounting plate 8 provides a stable mounting base for magnetic strip assembly 4, which can fix multiple magnetic strip assemblies 4 neatly and firmly, avoiding the effect of magnetic line concentration due to magnetic strip position displacement. At the same time, mounting plate 8 can also enhance the structural strength of the bottom of the entire coil, which facilitates the assembly and fixation of magnetic strip assembly 4 with support plate 2.

[0035] Reference Figure 1 and Figure 2The mounting plate 8 has multiple mounting holes 9 inside, which are used for installation. The mounting holes 9 can be adapted to fasteners of different specifications, making it easy to install the entire electromagnetic heating coil into various electromagnetic heating equipment. This ensures that the coil is firmly installed in the equipment and is not easily displaced due to vibration during equipment operation. At the same time, it improves the versatility of the coil and makes it adaptable to different installation scenarios. An insulating mica sheet 1 is installed on the top of the coil frame assembly 5. The spiral coil 6 is located between the insulating mica sheet 1 and the coil frame assembly 5. The insulating mica sheet 1 has good high temperature resistance and insulation. On the one hand, it can isolate the pot from the spiral coil 6, preventing the pot from directly contacting the coil and causing a short circuit or damage to the coil. On the other hand, it provides a stable placement surface for the pot. When the pot is placed on the insulating mica sheet 1, it can be more stably placed within the magnetic field range generated by the spiral coil 6, ensuring the uniformity and safety of heating.

[0036] Working principle: First, when heating is required, simply place the pot on the insulating mica sheet 1 and activate the spiral coil 6 to heat it up quickly. Since the spiral coils 6 are connected in series and arranged closely, they generate a continuous and evenly distributed magnetic field. When the pot is placed on the spiral coils 6, it can be heated relatively evenly over a large area, reducing local overheating or underheating.

[0037] Secondly, during the heating process, the magnetic strip assembly 4 can increase the inductance of the coil, concentrate magnetic lines of force, and reduce magnetic leakage. This can improve the efficiency of energy transmission and reduce interference with external electronic devices. In addition, the magnetic strip can also provide additional energy supplementation to increase the coil energy.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
