Description
Technical Field
[0001] This invention relates to the field of induction cooker technology, specifically to a high-efficiency heat dissipation induction cooker. Background Technology
[0002] An induction cooker is an electric cooking appliance that does not use open flame. The cooker itself does not heat up during use; it primarily uses electromagnetic induction to heat the food. The cooker operates at a relatively low temperature and is safer. Because the heat is emitted directly from inside the food, unlike other heat-generating appliances that significantly raise the ambient temperature during combustion, the user experiences greater comfort. Energy efficiency is also greatly improved. Since there is no combustion process, induction cookers do not produce toxic substances or carbon particles, and the cooktop is easy to clean, thus achieving safe heating.
[0003] Chinese invention patent CN103604145B discloses an induction cooker, comprising: an upper cover; a bottom plate; the bottom plate and the upper cover forming a receiving cavity; a main control board located in the receiving cavity, and the main control board is equipped with a heat-generating electrical component; and a fan located in the receiving cavity and supplying air to the main control board.
[0004] The aforementioned induction cooker can solve the problem of poor heat dissipation of some electrical components caused by different airflow at different locations inside the induction cooker, thereby enabling multiple electrical components to be effectively cooled and extending their service life. However, the induction cooker provided by the above invention uses an independent heat sink as the main body, supplemented by a fan blowing directly to assist in heat dissipation. The effect is singular and it is difficult to form a good airflow channel inside the induction cooker. Prolonged cooking can easily cause heat accumulation inside the cooker. Summary of the Invention
[0005] To address the shortcomings of existing technologies, this invention provides a high-efficiency heat dissipation induction cooker, which solves the problem that existing induction cookers mostly use fans to blow directly or use heat sinks to assist in heat dissipation of components, without corresponding air ducts inside to guide the rapid dissipation of heat, which easily leads to heat accumulation inside the induction cooker body.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a high-efficiency heat dissipation induction cooker, comprising a cooker body, a through-protrusion on the rear top of the cooker body, a housing fixedly mounted on the upper part of the through-protrusion, an air outlet on the top of the housing facing vertically upwards, a drive motor fixedly mounted on one side of the interior of the housing, a cross-flow fan fixedly connected to the output end of the drive motor, one end of the cross-flow fan rotatably connected to the other side of the interior of the housing, exhaust fan assemblies mounted on both sides of the cooker body, a mounting plate slidably connected to the rear of the cooker body, a controller mounted on one side of the upper part of the mounting plate, a high-frequency induction heating coil fixedly mounted on the upper part of the mounting plate, multiple heat dissipation fins arranged on one side of the high-frequency induction heating coil, the multiple heat dissipation fins being connected by a heat-conducting rod, heat spreaders mounted on both ends of the heat-conducting rod, heat-conducting pads arranged at the bottom of the heat spreaders, and the top of the controller contacting the heat spreaders through the heat-conducting pads.
[0007] By adopting the above technical solution, this induction cooker can form a dual-inlet, single-outlet air duct in actual use, with the cooperation of the cooker body and the through-protrusion. Specifically, when the induction cooker is started via the control panel, the control device on the upper part of the mounting plate is energized, activating the high-frequency induction heating coil. This coil converts the high-frequency alternating current into an alternating magnetic field to heat the metal vessel placed on the ceramic microcrystalline glass. During this process, the exhaust fan groups located on both sides of the cooker body and the drive motor installed inside the casing operate synchronously. The exhaust fan groups on both sides mainly provide air intake to the interior of the cooker body, while activating the drive motor drives the cross-flow fan fixedly connected to its output end to rotate, pushing air into the casing. The port blows out vertical hot air, forming a dual-inlet, single-outlet air duct through the coordinated operation of the structure. It should be noted that the airflow generated by the two exhaust fan groups is consistent with the blowing force generated by the cross-flow fan to ensure balanced and uniform airflow. This design increases the air intake volume inside the oven body while also blowing hot air vertically out from the top of the through-protrusion. The hot air rises quickly, increasing the heat dissipation speed. At the same time, when the user is cooking, the oil fumes generated can be partially blocked by the vertical hot air duct, causing the oil fumes to rise with the hot airflow into the range hood, effectively preventing oil fumes from floating on the walls and causing the walls to be difficult to clean over time.
[0008] Specifically, the above technical solution also achieves efficient heat dissipation for the control components. Specifically, during the use of the induction cooker, the heat spreader, which absorbs some of the heat from the control components through the thermal pad, transfers the heat to the grouped heat dissipation fins through the heat-conducting rod. The heat spreader is made of pure copper, which has high thermal conductivity. When external cold air enters the interior of the cooker through two exhaust fan groups, the cold air blows onto the heat dissipation fins and absorbs the heat on the fins. Compared with the direct-blowing structure of the fans used in traditional induction cookers, the heat conduction is more uniform and faster. Combined with independent air ducts, the heat generated by the heat dissipation fins can be quickly carried away, making the operation of the control components more stable and reliable.
[0009] Preferably, a ceramic microcrystalline glass is fixedly installed on the top of the furnace body, and a docking frame is fixedly connected to the bottom end of the ceramic microcrystalline glass.
[0010] By adopting the above technical solution, the ceramic microcrystalline glass serves to support metal utensils and as a top sealing structure of the furnace body, while the connecting frame plays a role in reinforcing the ceramic microcrystalline glass.
[0011] Preferably, a dispersion suppression ring is connected to the middle of the docking frame, the inner wall of the dispersion suppression ring is a vertical surface, and the inner wall of the dispersion suppression ring is coated with a reflective layer.
[0012] By adopting the above technical solution and setting a dispersion suppression ring with a reflective layer coated on the inner wall, the main purpose is to limit the scattering range of electromagnetic waves, reduce losses, and ensure the heating efficiency of metal utensils.
[0013] Preferably, a linear strip light is fixedly installed on the top front side of the furnace body, and a control panel is fixedly installed on one side of the front end of the furnace body.
[0014] By adopting the above technical solution, the present invention sets a linear light bar horizontally, the main purpose of which is to intuitively display the degree of heat. It adopts a flowing light form, which changes according to the heating degree of the high-frequency induction heating coil. It is independent of the furnace body and will not affect the display effect compared with traditional induction cooker products.
[0015] Preferably, a display screen is fixedly installed on the other side of the front end of the furnace body.
[0016] By adopting the above technical solution, the main function of the display screen is to display relevant information such as the operating mode of the induction cooker.
[0017] Preferably, through holes are provided on both rear sides of the furnace body, and fixing screws are installed inside the through holes.
[0018] By adopting the above technical solution, the mounting plate in this invention mainly slides inside the furnace body through the cooperation of the sliding groove and the sliding bar to achieve the effect of rapid extraction and propulsion. This design facilitates production assembly as well as subsequent fault repair and internal cleaning.
[0019] Preferably, the mounting plate has screw holes corresponding to the fixing screws on both rear sides.
[0020] By adopting the above technical solution, the mounting plate can be locked and prevented from shifting by connecting two fixing screws to the corresponding screw holes on the mounting plate.
[0021] Preferably, a heat insulation pad is provided at the bottom of the furnace body, and the interior of the furnace body is connected to the interior of the through protrusion.
[0022] Through the above technical solution, the main function of the heat insulation pad is to isolate a portion of the heat from being transferred to the cooking countertop, while the connection between the furnace body and the interior of the through protrusion is for the formation of an air duct. This induction cooker has the characteristics of easy maintenance, good heat dissipation, and excellent heating effect. Compared with traditional induction cooker products, it has better application value and usage effect.
[0023] This invention provides a high-efficiency heat dissipation induction cooker. It has the following beneficial effects:
[0024] 1. This invention, by designing a dual-inlet, single-outlet air duct inside the induction cooker, increases the air intake volume and airflow distance inside the cooker, while also allowing hot air to be blown vertically out from the top of the through-protrusion. The hot air rises quickly, increasing the heat dissipation rate. At the same time, when the user is cooking, the oil fumes generated can be partially blocked by the vertical hot air duct, causing the oil fumes to rise with the hot airflow and enter the range hood. This effectively prevents oil fumes from floating on the walls, which would make the walls difficult to clean over time.
[0025] 2. This invention uses multiple heat dissipation fins connected by heat-conducting rods, along with heat-conducting pads and heat spreaders, to evenly dissipate heat from the control devices. When two exhaust fan groups operate to allow external cold air to enter the furnace body, the cold air blows onto the heat dissipation fins, absorbing the heat on the fins. Compared to the direct-blowing structure of fans used in traditional induction cookers, the heat conduction is more uniform and faster. Combined with independent air ducts, it can quickly remove the heat generated by the heat dissipation fins, making the operation of the control devices more stable and reliable.
[0026] 3. The present invention sets up a dispersion suppression ring with a reflective layer on the inner wall. Its main purpose is to limit the scattering range of electromagnetic waves and reduce scattering loss, so as to ensure the heating efficiency of metal utensils.
[0027] 4. This invention features a sliding mounting plate that can slide inside the furnace body to support the corresponding heat dissipation and heating structures. This design facilitates production assembly, subsequent fault repair, and internal cleaning, making it highly practical. Attached Figure Description

[0039] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0040] Example:
[0041] Please see the appendix Figure 1 -Appendix Figure 5 This invention provides a high-efficiency heat dissipation induction cooker, including a cooker body 1. A through-protrusion 2 is provided on the rear top side of the cooker body 1. A housing 3 is fixedly installed on the upper part of the through-protrusion 2. The air outlet on the top of the housing 3 faces vertically upwards. A drive motor 4 is fixedly installed on one side of the interior of the housing 3. A cross-flow fan 5 is fixedly connected to the output end of the drive motor 4. One end of the cross-flow fan 5 is rotatably connected to the other side of the interior of the housing 3. Exhaust fan assemblies 6 are installed on both sides of the cooker body 1. A mounting plate 7 is slidably connected to the rear of the cooker body 1. A controller 8 is mounted on one side of the upper part of the mounting plate 7. A high-frequency induction heating coil 9 is fixedly mounted on the upper part of the mounting plate 7. Multiple heat dissipation fins 10 are arranged on one side of the high-frequency induction heating coil 9. The multiple heat dissipation fins 10 are connected by a heat-conducting rod 11. A heat spreader 12 is installed at both ends of the heat spreader 11. A heat-conducting pad 13 is provided at the bottom of the heat spreader 12. The top of the controller 8 contacts the heat spreader 12 through the heat-conducting pad 13. The heat-conducting rod 11 and the heat spreader 12 are both made of pure copper, which has good heat conduction effect.
[0042] Specifically, in actual use, this induction cooker can form a dual-inlet, single-outlet air duct with the cooperation of the cooker body 1 and the through protrusion 2. When the induction cooker is started via the control panel 18, the control device 8 on the upper part of the mounting plate 7 will be energized, causing the high-frequency induction heating coil 9 to start, converting the high-frequency alternating current into an alternating magnetic field to heat the metal utensil placed on the ceramic microcrystalline glass 14. During this process, the exhaust fan groups 6 located on both sides of the cooker body 1 and the drive motor 4 installed inside the casing 3 will operate synchronously. The exhaust fan groups 6 on both sides mainly send cold air into the interior of the cooker body 1, while by starting the drive motor 4, the cross-flow fan 5 fixedly connected to its output end can be driven to rotate, blowing cold air into the casing 3. The outlet blows out hot air that has absorbed the heat from the components. Through the coordinated operation of the structure, a dual-inlet, single-outlet air duct is formed. It should be noted that the airflow generated by the two exhaust fan groups 6 is consistent with the blowing force generated by the cross-flow fan 5 to ensure a balanced and uniform airflow. By implementing this design, the airflow inside the oven body 1 is increased, and hot air is blown vertically out from the top of the through protrusion 2. The hot air rises quickly, increasing the heat dissipation speed. At the same time, when the user is cooking, the oil fumes generated can be partially blocked by the vertical hot air duct, causing the oil fumes to rise with the hot airflow into the range hood. This effectively prevents oil fumes from floating on the wall, which would make the wall difficult to clean over time.
[0043] Specifically, the induction cooker provided in this embodiment can also achieve efficient heat dissipation of the control device 8. Specifically, during the use of the induction cooker, the heat spreader 12, which absorbs part of the heat of the control device 8 through the heat-conducting pad 13, will transfer the heat to the grouped heat dissipation fins 10 through the heat-conducting rod 11. When external cold air enters the interior of the cooker body 1 through the two exhaust fan groups 6, the cold air will blow onto the heat dissipation fins 10 and absorb the heat on the heat dissipation fins 10. Compared with the direct fan blowing structure used in traditional induction cookers, the heat conduction is uniform and fast. With the help of independent air ducts, the heat generated by the heat dissipation fins 10 can be quickly carried away, making the operation of the control device 8 more stable and reliable.
[0044] Further, please refer to the appendix. Figure 1 In the induction cooker provided in this embodiment, a ceramic microcrystalline glass 14 is fixedly installed on the top of the cooker body 1, and a docking frame 15 is fixedly connected to the bottom of the ceramic microcrystalline glass 14.
[0045] Specifically, in the actual application of this induction cooker, the ceramic microcrystalline glass 14 serves to support the metal utensils and acts as the top sealing structure of the cooker body 1, while the docking frame 15 plays the role of assisting in reinforcing the ceramic microcrystalline glass 14.
[0046] Further, please refer to the appendix. Figure 7 -Appendix Figure 8A dispersion suppression ring 16 is connected to the middle of the docking frame 15. The inner wall of the dispersion suppression ring 16 is a vertical surface, and a reflective layer is coated on the inner wall of the dispersion suppression ring 16. The reflective layer can be a mirror reflective layer. Specifically, the main function of the dispersion suppression ring 16 is to reduce the scattering loss of electromagnetic waves in order to ensure the heating efficiency of the metal utensils.

Specifically, in this embodiment, a linear light bar 17 is set horizontally. Its main purpose is to intuitively display the size of the heat. It adopts the form of a flowing light and changes according to the heating degree of the high-frequency induction heating coil 9. It is independent of the furnace body 1 and will not affect the display effect compared with traditional induction cooker products.
[0048] Further, please refer to the appendix. Figure 1 A display screen 19 is fixedly installed on the other side of the front end of the furnace body 1. The main function of the display screen 19 is to display relevant information such as the operating mode of the induction cooker.
[0049] Further, please refer to the appendix. Figure 3 Both sides of the furnace body 1 have through holes at the rear, and fixing screws 20 are installed inside the through holes. Both sides of the mounting plate 7 have screw holes 21 corresponding to the fixing screws 20 at the rear. The mounting plate 7 slides inside the furnace body 1 mainly through the cooperation of the sliding groove and the sliding strip. When it is fixed, it is fixed by two fixing screws 20 and the corresponding screw holes 21 on the mounting plate 7 to prevent it from shifting. This design facilitates production assembly and subsequent fault repair and internal cleaning.
