[0055] In existing electromagnetic heating devices, the coil assembly is located below the electric heating device. Because the air cannot fully contact the coil assembly, heat tends to accumulate in specific areas. This not only affects the stability of the electromagnetic heating device but also has a certain thermal impact on cooking appliances.

[0056] To solve the above technical problems, such as Figures 1 to 3 As shown, this utility model discloses a cooking appliance 100, comprising a main body 1, an electric heating device 2, an electromagnetic heating device 3, at least one air baffle 4, at least one fan assembly 5, and a control device 6. The main body 1 includes a panel 11, with a heating area 111 on its upper side. The electric heating device 2 is disposed within the main body 1 and is used to heat the cookware placed in the heating area 111. The electric heating device 2 includes at least two heating elements 21 arranged in sections. The electromagnetic heating device 3 is disposed within the main body 1 and located below the electric heating device 2. The electromagnetic heating device 3 includes at least one coil assembly 31, which is used to electromagnetically heat the cookware placed in the heating area 111. At least one air baffle 4 is disposed within the main body 1 and located below the electromagnetic heating element. The lower side of the device 3 and the upper end of the wind baffle 4 face the electromagnetic heating device 3; at least one fan assembly 5 includes a first fan assembly 51, which is disposed in the main body 1, and the air outlet of the first fan assembly 51 faces the wind baffle 4 so that it can blow air onto the wind baffle 4 so that the wind baffle 4 can guide the airflow blown out by the first fan assembly 51 to the electromagnetic heating device 3; the control device 6 is electrically connected to the fan assembly 5, the electric heating device 2 and the electromagnetic heating device 3 so that it can control the two heating parts 21 of the electric heating device 2 to work independently, and control the electromagnetic heating device 3 and the fan assembly 5 to work.

[0057] In the technical solution of this utility model, by setting the electric heating device 2 as at least two heating parts 21 in partitions, targeted heating of different parts of the cookware placed in the heating area 111 can be achieved to meet different cooking needs, such as local high-temperature heating, thereby improving the flexibility and precision of heating. By setting at least one coil assembly 31, the cookware placed in the heating area 111 is electromagnetically heated using the principle of electromagnetic induction. Compared with traditional heating methods, the heating efficiency is higher, the temperature can rise quickly, and the heat distribution is more uniform. By setting at least one wind-blocking rib 4 on the lower side of the electromagnetic heating device 3, with its upper end facing the electromagnetic heating device 3, and simultaneously setting a first fan assembly 51 with its air outlet facing the wind-blocking rib 4, the air blown by the first fan assembly 51 is guided to the electromagnetic heating device 3 through the wind-blocking rib 4, improving the airflow path, allowing the airflow to fully contact the electromagnetic heating device 3, and allowing the heat to be dissipated more smoothly. This improves the heat dissipation of the coil assembly 31 in the electromagnetic heating device 3, thereby improving the stability of the electromagnetic heating device 3 and reducing the thermal impact of the cooking appliance 100.

[0058] like Figure 4 and Figure 5 As shown, in one embodiment, a gap is reserved between the air baffle 4 and the lower side of the electromagnetic heating device 3. This arrangement avoids potential heat conduction problems caused by direct contact between the air baffle 4 and the electromagnetic heating device 3, ensuring that heat can be dissipated more smoothly from the electromagnetic heating device 3. The reserved gap provides a buffer space for airflow after passing through the air baffle 4, further optimizing the airflow path and improving the stability and uniformity of heat dissipation. Furthermore, it facilitates fine-tuning of the relative positions of the air baffle 4 and the electromagnetic heating device 3 during manufacturing and installation to adapt to different production processes and installation requirements, improving product compatibility and maintainability.

[0059] Furthermore, in one embodiment, the gap between the air baffle 4 and the lower side of the electromagnetic heating device 3 is 'a', where 5mm ≥ a ≥ 2mm. This arrangement ensures that the airflow has sufficient space to pass through, preventing the airflow from being severely obstructed and affecting the heat dissipation effect due to an excessively small gap, and also preventing the airflow from being too dispersed and reducing the airflow intensity guiding the electromagnetic heating device 3 due to an excessively large gap. This achieves a good balance between heat dissipation efficiency and the stability of airflow guidance.

[0060] Furthermore, in one embodiment, the air baffle 4 is positioned corresponding to the coil assembly 31 to guide airflow towards the coil assembly 31. This configuration, by specifically positioning the air baffle 4 to correspond to the coil assembly 31, allows for more precise guidance of airflow towards the coil assembly 31, ensuring that the heat generated by the coil assembly 31 during operation is promptly carried away by the airflow. This effectively reduces the temperature of the coil assembly 31, minimizing the impact of high temperatures on its performance and lifespan. It also allows for more concentrated and efficient heat dissipation, improving the overall heat dissipation efficiency of the electromagnetic heating device 3.

[0061] like Figure 6 and Figure 7 As shown, it can be understood that the electromagnetic coil assembly 31 can be provided with one or more coil assemblies 31 to adapt to different heating requirements. Specifically, in one embodiment, multiple coil assemblies 31 are provided, including a first coil assembly 311 and a second coil assembly 312. The first coil assembly 311 is located on the lower side of the electric heating device 2, and the second coil assembly 312 is located on the periphery of the first coil assembly 311. Multiple air-blocking ribs 4 are provided, including a first air-blocking rib 41 and a second air-blocking rib 42. The first air-blocking rib 41 is set on the winding segment of the first coil assembly 311 away from the first fan assembly 51, and the second air-blocking rib 42 is located on the side of the first air-blocking rib 41 away from the first fan assembly 51, and is set on the winding segment of the second coil assembly 312 away from the first fan assembly 51. With this configuration, by placing the second coil assembly 312 on the periphery of the first coil assembly 311, a wider heating range and different heating power can be provided through the coordinated work of different coil assemblies 31 to adapt to various different heating requirements and meet the heating effect requirements in different scenarios. The placement of the air baffles 4 allows for more precise airflow guidance, enabling the airflow to dissipate heat from different winding segments of the coil assembly 31. This ensures that each coil assembly 31 receives effective cooling during operation, preventing localized overheating that could affect its performance and lifespan, and improving the overall heat dissipation efficiency and stability of the electromagnetic heating device 3. Furthermore, the arrangement of multiple air baffles 4 corresponding to multiple coil assemblies 31 makes the entire device more compact in structure.

[0062] like Figures 8 to 10 As shown, it can be understood that one end of the baffle 4 can be positioned towards the air outlet of the first fan assembly 51. This configuration guides the airflow from the air outlet of the first fan assembly 51 to the baffle 4, thereby increasing the airflow volume of the first fan assembly 51 passing through the baffle 4 and reducing wasted airflow.

[0063] Furthermore, in one embodiment, the second air baffle 42 is connected to the first air baffle 41 at the end near the air outlet of the first fan assembly 51, and the first air baffle 41 and the second air baffle 42 are integrally formed. This integral formation makes the connection between the first air baffle 41 and the second air baffle 42 more secure, less prone to loosening or deformation during use, and able to maintain good airflow guidance function for a long time, reducing the risk of failure due to structural instability.

[0064] It is understood that the upper height of the first and second air-blocking ribs 41 and 42 is not particularly limited. For example, in one embodiment, at least one section of the upper end of the second air-blocking rib 42 is positioned higher than the corresponding upper end of the first air-blocking rib 41. This configuration, by making the upper end of the second air-blocking rib 42 higher than the first air-blocking rib 41, creates a staggered structure in the vertical direction, causing airflow to be obstructed at different heights as it passes through, thereby more effectively guiding the airflow along a specific path. This better directs the airflow to the coil assemblies 31 at different locations, ensuring that the airflow can more evenly cover each coil assembly 31, improving the uniformity and effectiveness of heat dissipation.

[0065] It is understandable that the coil assembly 31 can be located at the bottom of the electric heating device 2, but the bottom of the electric heating device 2 will generate some heat, which will interfere with the coil assembly 31. Therefore, in one embodiment, the electromagnetic heating device 3 further includes a support 32, on which the coil assembly 31 is mounted. The support 32 is provided with through holes 33 extending through its upper and lower sides. At least one air baffle 4 is provided adjacent to the through holes 33 so that the airflow under the support 32 can be guided to the upper side of the support 32 through the through holes 33. This configuration, by placing the coil assembly 31 on the bracket 32 ​​and providing through-holes 33 on the bracket 32 ​​extending from both the top and bottom, along with at least one air-blocking rib 4 positioned adjacent to the through-holes 33, allows airflow from the lower side of the bracket 32 ​​to the upper side via the through-holes 33. This provides a better heat dissipation environment for the coil assembly 31, ensuring that both sides of the coil assembly 31 are cooled by the airflow from the first fan assembly 51. This dissipates the heat generated during operation, further reducing the temperature of the coil assembly 31 and preventing malfunctions or performance degradation due to heat accumulation. The coil assembly 31 operates at a relatively low temperature, improving its performance and stability.

[0066] In one embodiment, multiple coil assemblies 31 are provided, including a first coil assembly 311 and a second coil assembly 312. The first coil assembly 311 is located below the electric heating device 2, and the second coil assembly 312 is located around the first coil assembly 311. Multiple air-blocking ribs 4 are provided, including a first air-blocking rib 41 and a second air-blocking rib 42. The first air-blocking rib 41 is provided corresponding to the winding segment on the first coil assembly 311 away from the first fan assembly 51, and the second air-blocking rib 42 is located on the first air-blocking rib 41 away from the first fan assembly. On one side of 51, and corresponding to the winding segment on the second coil assembly 312 away from the first fan assembly 51; multiple through holes 33 are provided, including a first through hole 331 and a second through hole 332. The first through hole 331 is located inside the first coil assembly 311, and at least one first through hole 331 is located corresponding to the first wind-blocking rib 41. The second through hole 332 is located between the first coil assembly 311 and the second coil assembly 312, and is located adjacent to the second coil assembly 312. At least one second through hole 332 is located corresponding to the second wind-blocking rib 42. With this configuration, by placing the first through hole 331 inside the first coil assembly 311 and corresponding to the first wind-blocking rib 41, and placing the second through hole 332 between the first and second coil assemblies 31 and corresponding to the second wind-blocking rib 42, airflow can be guided more precisely. This allows the airflow to cool the coil assembly 31 at different locations, especially the winding segment far from the first fan assembly 51. This effectively removes heat, preventing overheating in these areas due to poor heat dissipation and thus improving the overall heat dissipation efficiency of the electromagnetic heating device 3. This ensures the normal operation and lifespan of the coil assembly 31. The combination of multiple through-holes 33 and different air-blocking ribs 4 results in a more uniform and rational distribution of airflow within the device, preventing localized concentration or turbulence. This helps to stably reduce the overall temperature of the device, ensuring that all parts operate at a suitable temperature, thus improving the device's reliability and stability.

[0067] In one embodiment, the minimum distance between the second baffle 42 and the outer edge of the second through hole 332 is b, where 0 mm < b ≤ 10 mm. This setting, within this distance range, ensures that the baffle 4 effectively guides airflow while reducing excessive obstruction to airflow through the through hole 33 due to the baffle 4 being too close to the outer edge of the through hole 33. It also ensures that the baffle 4 fully guides airflow in a specific area, allowing airflow to pass smoothly through the through hole 33 and reach the corresponding winding segment of the second coil assembly 312, thus achieving better heat dissipation.

[0068] In one embodiment, the plurality of vias 33 further includes a third via 333 disposed between the first coil assembly 311 and the second coil assembly 312, the third via 333 being disposed adjacent to the second coil assembly 312. This arrangement, by adding the third via 333 between the first coil assembly 311 and the second coil assembly 312, further widens the airflow channel, allowing more airflow to pass through this area. The third via 333 disposed adjacent to the second coil assembly 312 can more directly guide airflow to the vicinity of the second coil assembly 312, enhancing the heat dissipation effect on the second coil assembly 312.

[0069] It is understandable that the panel 11 will collapse to some extent when heated. Therefore, in one embodiment, the electric heating device 2 further includes a mounting base, which is disposed on the upper side of the bracket 32. The panel 11 is covered on the upper side of the mounting base, and the two heating elements 21 are disposed inside the mounting base. The main body 1 also includes an elastic support 12, which is disposed between the lower side of the bracket 32 ​​and the main body 1 to support the bracket 32. With this arrangement, the elastic support 12, disposed between the lower side of the bracket 32 ​​and the main body 1, can provide stable support for the bracket 32. When the panel 11 collapses to some extent when heated, the elastic support 12 can buffer the stress caused by this deformation, preventing the bracket 32 ​​from being excessively deformed or damaged due to the collapse of the panel 11, thereby ensuring the structural stability of the entire electric heating device 2 and enabling it to maintain good shape and performance during operation.

[0070] In one embodiment, the cooking appliance 100 further includes a second fan assembly 52, and the control device 6 includes a circuit board assembly 61. Both the second fan assembly 52 and the circuit board assembly 61 are disposed within the main body 1, with the air outlet of the second fan assembly 52 facing the circuit board assembly 61. This arrangement, with the air outlet of the second fan assembly 52 facing the circuit board assembly 61, allows airflow to be directly directed towards the circuit board assembly 61, effectively dissipating heat from the circuit board. During operation, the circuit board generates heat; the forced airflow from the second fan assembly 52 quickly removes this heat, reducing the risk of malfunction or performance degradation due to overheating, ensuring the normal operation of the circuit board, and improving the reliability and stability of the cooking appliance 100.

[0071] like Figure 11As shown, in one embodiment, at least one coil assembly 31 is located below the electromagnetic heating device 3 and is at least partially offset from at least one heating element 21. This arrangement, by partially offsetting the heating element 21 from the coil assembly 31, allows the coil assembly 31 and the heating element 21 to be partially opened. This ensures that only a portion of the heat generated by the heating element 21 during operation can be conducted to the surface of the coil assembly 31, reducing the impact of the electric heating device 2 on the temperature rise of the coil assembly 31. This alleviates the overheating problem caused by the heat transferred downwards from the electric heating device 2 combined with the heat generated by the coil assembly 31 itself, reducing the probability of damage to the insulation layer of the coil assembly 31, protecting the coil assembly 31 from burning out, and simultaneously increasing the heating power of the cooking appliance 100.

[0072] In one embodiment, the two heating elements 21 include a first heating element 211 and a second heating element 212, with the second heating element 212 located around the first heating element 211. This configuration allows for more diverse heating modes by controlling the first heating element 211 and the second heating element 212 to heat simultaneously or separately.

[0073] In one embodiment, the two heating elements 21 are arranged in parallel so that they can be independently controlled by the control device 6. This arrangement, with the two heating elements 21 connected in parallel and independently controlled by the control device 6, allows for flexible adjustment of the heating power of each heating element 21 as needed in different cooking scenarios.

Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
