Description

Technical Field

[0001] This utility model relates to the field of induction cooker technology, specifically a multi-burner induction cooker structure. Background Technology

[0002] An induction cooker generates an alternating magnetic field through a coil. When a metal object is placed on the induction cooker, eddy currents are generated in the metal object, thereby achieving electromagnetic heating.

[0003] Multi-burner induction cookers achieve simultaneous heating of multiple burners by increasing the number of coils. When multiple burners are working at the same time, the internal coils and electrical components on the circuit board generate a large amount of heat, which needs to be dissipated through a heat dissipation structure. Current heat dissipation structures include heat dissipation fins and fans. The heat dissipation fins are mounted on the circuit board, and the fan dissipates heat from the heat dissipation fins. That is, the current heat dissipation structure only dissipates heat from the circuit board and cannot dissipate heat from the coils, resulting in poor heat dissipation effect.

[0004] To address this, relevant technical personnel have developed a heat dissipation structure for a multi-head induction cooker, as disclosed in Chinese utility model patent CN201020279857.9. This structure includes a vortex fan, a first coil, and a second coil installed within the casing. The first air intake of the vortex fan faces the bottom of the casing, while the first air outlet of the vortex fan is laterally positioned and delivers air into the interior space of the casing. Corresponding air diffusers are located on the sides of the casing. An air guide is positioned along the air outlet path of the vortex fan, and the air guide has a diversion port. A second air intake is located on the top side of the vortex fan, and a second air outlet is located on its side. The second air outlet faces a different direction than the first air outlet. The air delivered by the vortex fan not only blows in the direction corresponding to its air outlet but also has its direction changed by the diversion port of the air guide and the second air outlet, improving heat dissipation in dead zones of ordinary air ducts, achieving a large-area cooling effect. However, in actual use, due to the change in the direction of airflow, the second coil cannot be effectively cooled. In addition, since the vortex fan needs to blow air in different directions and the first and second coils are on different cooling air ducts, the space utilization rate inside the induction cooker is low, and the internal space of the induction cooker cannot be used reasonably, resulting in space waste.

[0005] Therefore, further improvements are necessary. Utility Model Content

[0006] The present invention aims to provide a multi-burner induction cooker structure to overcome the shortcomings of the prior art.

[0007] A multi-head induction cooker structure designed for this purpose includes a bottom shell, on which a coil plate, an EMC board, and a fan are disposed. At least two coil plates are disposed, and the at least two coil plates are respectively located on both sides or on the same side of the EMC board. Each of the at least two coil plates is electrically connected to an electronic control board or is electrically connected to an electronic control board. The electronic control board is located below the coil plates and is electrically connected to the EMC board. The fan is located below the coil plates and on one side of the electronic control board.

[0009] The heat dissipation channel is provided in a plurality of ways, which are independent of each other and spaced apart. The EMC board is located between adjacent heat dissipation channels, or the EMC board is located on one side of the heat dissipation channel.

[0010] The fan, the electronic control board, and at least two coils are arranged in the same heat dissipation channel.

[0011] An EMC board assembly part is provided between the adjacent heat dissipation channels, and the EMC board is fixedly assembled on the EMC board assembly part.

[0012] The electronic control board is provided with at least one, and at least one of the electronic control boards is electrically connected to at least two of the coil disks. The at least two coil disks are located on the same side of the EMC board and are spaced apart front to back or left to right along the heat dissipation channel.

[0013] At least two coil disks are designated as a first coil disk and a second coil disk. The bottom shell is provided with a first coil disk assembly part and a second coil disk assembly part. The first coil disk is fixedly assembled on the first coil disk assembly part and located above the fan. The second coil disk is fixedly assembled on the second coil disk assembly part and located above the electronic control board.

[0014] An air inlet enclosure is provided around the air inlet, and the air inlet enclosure has an opening facing the air outlet. The fan is located inside the air inlet enclosure.

[0016] A fan assembly is provided on the air vent enclosure or the bottom shell, and the fan is fixedly mounted on the fan assembly and positioned above the air inlet.

[0017] This invention, through structural improvements, places at least two coil discs on either side or the same side of the EMC board, allowing the EMC board to be positioned between or on one side of the at least two coil discs. Each of these coil discs is electrically connected to an electrical control board, or they are connected to a common electrical control board. This allows the at least two coil discs to be controlled separately by their respective control boards or simultaneously by a common control board. Furthermore, the control board is positioned below the coil discs and electrically connected to the EMC board, enabling the EMC board to be matched with multiple main control boards to control multiple coil discs. This allows a single furnace body to operate multiple furnace heads, increasing the product's usability. The fan is placed below the coil discs and to one side of the control board. This allows the EMC board, fan, control board, and at least two coil discs to utilize the space in the bottom shell efficiently, improving space utilization. Moreover, a single fan can simultaneously dissipate heat from the control board and at least two coil discs, resulting in high heat dissipation efficiency and effectively reducing production costs, making it highly practical.

[0021] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] See Figures 1-3 The structure of this multi-head induction cooker includes a bottom shell 1, on which a coil, an EMC plate 2, and a fan 3 are arranged. There are at least two coils, which are located on both sides or on the same side of the EMC plate 2. Each of the at least two coils is electrically connected to an electronic control board 4 or they are electrically connected to the same electronic control board 4. The electronic control board 4 is located below the coils and is electrically connected to the EMC plate 2. The fan 3 is located below the coils and on one side of the electronic control board 4.

[0024] In this embodiment, at least two coils are placed on either side or the same side of the EMC board 2, so that the EMC board 2 can be set between or on one side of the at least two coils. Each of these at least two coils is electrically connected to an electronic control board 4, or they are electrically connected to a common electronic control board 4, so that the at least two coils can be controlled separately by their respective electronic control boards 4, or simultaneously by a common electronic control board 4. In addition, the electronic control board 4 is placed below the coils and electrically connected to the EMC board 2, so that the EMC board can match multiple main control boards 4 to control multiple coils, allowing a single furnace body to achieve multi-burner operation and improving the product's application range. The fan 3 is placed below the coils and on one side of the electronic control board 4, thereby allowing the EMC board 2, fan 3, electronic control board 4, and at least two coils to make reasonable use of the space in the bottom shell 1, thereby improving the space utilization rate of the bottom shell 1. Moreover, a single fan 3 can achieve simultaneous heat dissipation for the electronic control board 4 and at least two coils, which not only has high heat dissipation efficiency, but also effectively reduces production costs and has strong practicality.

[0025] The bottom shell 1 is provided with an air inlet 5 and an air outlet 6, forming a heat dissipation channel between the air inlet 5 and the air outlet 6. The coil, and / or EMC board 2, and / or fan 3, and / or electronic control board 4 are located in the heat dissipation channel. In this way, the coil, and / or EMC board 2, and / or fan 3, and / or electronic control board 4 are all located in the heat dissipation channel, and the ambient temperature air entering from the air inlet 5 can dissipate heat from the coil, and / or EMC board 2, and / or fan 3, and / or electronic control board 4 before being discharged from the air outlet 6.

[0026] There are several heat dissipation channels, which are independent of each other and spaced out. The EMC board 2 is located between adjacent heat dissipation channels, or the EMC board 2 is located on one side of a heat dissipation channel.

[0027] In this embodiment, several heat dissipation channels are independent of each other to avoid heat dissipation interference between each heat dissipation channel and ensure that each heat dissipation channel can dissipate heat independently. In addition, the EMC board 2 can be placed between adjacent heat dissipation channels or on one side of the heat dissipation channel without occupying the space of the heat dissipation channel, thus reducing the space occupied by the heat dissipation channel.

[0028] A fan 3, an electronic control board 4, and at least two coils are arranged in the same heat dissipation channel, so that the fan 3, the electronic control board 4, and at least two coils can be cooled by one heat dissipation channel, thereby improving the heat dissipation effect and space utilization.

[0029] An EMC board assembly part 7 is provided between adjacent heat dissipation channels, and the EMC board 2 is fixedly assembled on the EMC board assembly part 7, thereby ensuring that the EMC board 2 can be stably assembled between adjacent heat dissipation channels.

[0030] The electronic control board 4 is provided with at least one, and at least one electronic control board 4 is electrically connected to at least two coil disks. The at least two coil disks are located on the same side of the EMC board 2 and are arranged at intervals in front and behind or left and right along the heat dissipation channel.

[0031] Specifically, at least two coil disks are a first coil disk 9 and a second coil disk 10. The bottom shell 1 is provided with a first coil disk assembly part 11 and a second coil disk assembly part 12. The first coil disk 9 is fixedly assembled on the first coil disk assembly part 11 and located above the fan 3. The second coil disk 10 is fixedly assembled on the second coil disk assembly part 12 and located above the electronic control board 4.

[0032] In this embodiment, the second coil disk 10 and the first coil disk 9 are located in the upper front and rear areas of the heat dissipation channel, and the electronic control board 4 and the fan 3 are located in the lower front and rear areas of the heat dissipation channel. This effectively utilizes the space of the heat dissipation channel. Moreover, one fan 3 can effectively dissipate heat from the second coil disk 10, the first coil disk 9, and the electronic control board 4. The other electronic control board 4 can control the second coil disk 10 and the first coil disk 9, making it highly practical.

[0033] An air inlet 5 is surrounded by an air outlet enclosure 13, and the air outlet enclosure 13 has an opening 14 facing the air outlet 6. The fan 3 is located inside the air outlet enclosure 13.

[0034] The air intake is blocked by the air intake panel 13 so that the cooling air can only be blown out from the opening 14 of the panel, thereby reducing the loss of cooling air.

[0035] The bottom shell 1 is provided with an electric control board assembly part 8. The electric control board 4 is fixedly assembled on the electric control board assembly part 8 and located between the enclosure opening 14 and the air outlet 6, so that the electric control board 4 can be stably assembled between the enclosure opening 14 and the air outlet 6.

[0036] A fan assembly part 15 is provided on the air vent enclosure 13 or the bottom shell 1, and the fan 3 is fixedly assembled on the fan assembly part 15 and placed above the air inlet 5.

[0037] In this embodiment, the fan assembly part 15 is set on the air vent enclosure 13, and the fan 3 is suspended above the air inlet 5 after assembly, which not only improves the assembly stability of the fan 3, but also increases the air volume of the cooling air.

[0038] The above describes the preferred embodiments of this utility model, illustrating and describing its basic principles, main features, and advantages. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made without departing from the spirit and scope of this utility model, and all such changes and modifications fall within the scope of protection of this utility model as defined by the appended claims and their equivalents.
