Description

Technical Field

[0001] This utility model relates to the field of electromagnetic heating technology, and in particular to an electromagnetically heated open-flame rapid boiler. Background Technology

[0002] Electromagnetic heating rapid boilers are high-efficiency thermal energy devices designed based on the principle of electromagnetic induction. By passing high-frequency alternating current through a coil, an alternating magnetic field is generated, causing the metal components inside the boiler (such as pipes and containers) to heat up rapidly due to eddy current effects and hysteresis losses, efficiently converting energy into heat. Its features include: rapid heating, reaching the preset temperature within minutes; thermal efficiency exceeding 95%, low energy consumption and precise temperature control; and safe and environmentally friendly operation with no open flame or exhaust emissions. The equipment mainly consists of an electromagnetic coil, insulation structure, and intelligent temperature control system. It is widely used in industrial heating, hot water preparation, and chemical reaction heating, and is particularly suitable for scenarios requiring rapid heating, energy saving and carbon reduction, or precise temperature control, significantly improving thermal energy utilization efficiency and simplifying traditional heating processes.

[0003] The working principle of an electromagnetic heating rapid boiler is based on the electromagnetic induction effect: an energized coil (usually made of copper) is connected to a high-frequency alternating current (20kHz~1MHz), generating an alternating magnetic field. When the magnetic field passes through the metal pipes or containers inside the boiler (such as iron, steel, or other magnetically conductive materials), the free electrons inside the metal are excited by the alternating magnetic field, forming eddy currents (circular induced currents). These eddy currents generate Joule heat (Q=I²Rt) under the action of the metal resistance, while the ferromagnetic material experiences hysteresis losses due to repeated magnetization of magnetic domains. Both factors contribute to the rapid heating of the metal. The heat is transferred to the medium (water or other fluids) through conduction and convection, achieving the heating target. During this process, the coil itself may generate a small amount of heat due to the skin effect of the high-frequency current, but the core heat source is the metal being heated. This process features high thermal efficiency (over 95%), rapid heating (reaching temperature in minutes), and concentrated energy. Furthermore, a smart temperature control system precisely adjusts the output power to ensure stable operation.

[0004] In existing technologies, some traditional induction cookers are limited by heating methods, coil design, and heat insulation effects. The maximum heating temperature of the wok is usually relatively low, around 300 degrees Celsius, and the temperature rise is slow. This leads to longer heating time, especially for stewing and frying, which requires longer preheating time, affecting the rhythm of kitchen operations and causing a decline in the taste of food. Slow heating means that energy is continuously dissipated to the environment through the coil and panel, reducing thermal efficiency and increasing power consumption. Long-term use results in energy waste. Therefore, an electromagnetic heating open flame rapid boiler is proposed to solve the above problems. Utility Model Content

Both ends of L-shaped connecting rod 6 are rotatably connected to push rod 7. Push rod 7 provides clamping force for easy clamping and loosening. A clamping block 8 is fixedly connected to the adjacent side of push rod 7. The clamping block 8 is used to clamp square block 4, so that pressure ring 3 is pressed. One end of one push rod 7 is rotatably connected to rotating shaft 9. Rotating shaft 9 is used to rotate, so that rotating handle 10 can rotate. Rotating handle 10 is fixedly connected to the outside of rotating shaft 9. Rotating handle 10 is used to grip and fix, so as to push push rod 7 and fix push rod 7. A heating component is detachably connected to the bottom of upper shell 1. The heating component is used to heat heating pot core 14.

[0025] The clamping block 8 is externally slidably connected to the inside of the square block 4. The top of the upper shell 1 is fixedly connected to glass wool 12. The inner wall of the glass wool 12 is fixedly connected to high-temperature cement 13. The inner wall of the high-temperature cement 13 is fixedly connected to the heating pot core 14. Both the glass wool 12 and the high-temperature cement 13 are used to isolate the heating pot core 14 and prevent the heating pot core 14 from burning other components. The front side of the upper shell 1 is provided with a handle groove 11. The outer wall of the rotating handle 10 is slidably connected to the inner wall of the handle groove 11.

[0026] Reference Figure 1 , Figure 2 and Figure 4The heating assembly includes a lower shell 2, the top of which is detachably connected to the bottom of the upper shell 1. The lower shell 2 is used to fix the heating assembly and facilitate its installation. Multiple external fixing ridges 15 are detachably connected inside the top of the lower shell 2. The external fixing ridges 15 are used to fix the copper coil 20 and prevent it from falling off. The top of the multiple external fixing ridges 15 is fixedly connected to a fixing ring 16. Multiple bolts 17 are threaded inside the fixing ring 16. The fixing ring 16 and the bolts 17 fix the entire copper coil 20 into a whole. Fixing plates 19 are threaded in pairs on the outside of the multiple bolts 17. The fixing plates 19 fix the copper coil 20 in the middle. Multiple internal fixing ridges 18 are fixedly connected to the bottom of the fixing ring 16. The internal fixing ridges 18 fix the copper coil 20 inside. Copper coils 20 are detachably connected to both the inner and outer sides of the multiple fixing plates 19. The copper coils 20 are used to conduct electricity and facilitate the formation of a magnetic field.

[0027] One end of the copper coil 20 is fixedly connected to the host 21, which provides power to energize the copper coil 20.

The bottom end of the fixing ring 16 is detachably connected to the top end of the fixing plate 19.

[0028] Working principle: When in use, the copper coil 20 is energized, and the current flows along the copper coil 20, generating a high-frequency alternating magnetic field. This causes eddy current loss and hysteresis loss inside the heating pot core 14, thereby generating heat and achieving heat storage. The rotating handle 10 is pushed, causing it to enter the handle groove 11 and rotate to a vertical position so that it cannot move forward. The pushing of the rotating handle 10 drives the push rod 7 to move backward, thereby causing the L-shaped connecting rod 6 to rotate around the fixed column 5. The rotation of the L-shaped connecting rod 6 causes the push rod 7 to move to the same side. The movement of the push rod 7 to the same side causes the clamping block 8 to enter the square block 4, clamping the square block 4 and fixing the pressure ring 3, thereby fixing the heating pot core 14.

[0029] The copper coil 20 adopts a double-layer stacked coil design. First, the copper coil 20 is wound around the outer wall of the fixing plate 19. Then, the copper coil 20 is inserted through the hole at the bottom of the fixing plate 19 and wound around the inner wall of the fixing plate 19. At this time, the inner fixing ridge 18 and the outer fixing ridge 15 are installed. Then, the fixing ring 16 is fixed to the top of the fixing plate 19 with bolts 17 to fix the copper coil 20.
