Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic cookers, and specifically provides a multi-head electromagnetic cooker. Background Art

[0002] Currently, most of the induction cookers on the market are single-burner, and the overall efficiency of single-burner induction cookers is relatively low. When multiple cooking methods need to be performed simultaneously, multiple induction cookers need to be configured.

[0003] Based on this, multi-head electromagnetic cookers (multi-burner electromagnetic cookers) came into being. Multi-head electromagnetic cookers are usually equipped with two or more coil disks, and each coil disk can be individually controlled to generate heat, so that multiple different pots can be heated at the same time. Multi-head electromagnetic cookers are usually equipped with multiple electronic control boards, so a corresponding number of radiators and fans are required to dissipate heat for the electronic control boards, which not only makes the structure of the entire electromagnetic cooker complex and bulky, but also has high costs. In order to reduce costs, some electromagnetic cookers reduce the number of fans, such as using one fan to dissipate heat for two electronic control boards. However, due to the lack of a special air duct structure and the limitation of the arrangement of the electronic control boards, the heat dissipation effect of each electronic control board is uneven, affecting the overall heating performance of the electromagnetic cooker.

[0004] Accordingly, the art needs a new electromagnetic cooker to solve the above problems. Utility Model Content

[0039] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not used to limit the protection scope of the present invention. Those skilled in the art can make adjustments to them as needed to adapt to specific applications. For example, although the following embodiments are described using an embedded multi-head electromagnetic cooker as an example, this is not restrictive. The technical solution of the present invention is also applicable to a desktop multi-head electromagnetic cooker.

Therefore, the orientation in the following embodiments cannot be understood as a limitation of the present invention. In addition, ordinal numbers such as "first" and "second" are only for the convenience of description and are not used to indicate or imply relative importance.

[0042] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0043] In addition, in the following embodiments, “not marked” means that a corresponding structure is shown in the drawings but is not marked, and “not shown in the drawings” means that the corresponding structure is not shown in the drawings.

[0044] Refer to the following Figures 1 to 5 The multi-head electromagnetic cooker provided by the utility model is described.

[0045] like Figure 1As shown in , this embodiment provides an embedded multi-head electromagnetic cooker, which includes a bottom shell 2 and a microcrystalline glass panel 1 connected to the top of the bottom shell 2, and the microcrystalline glass panel 1 is bonded to the bottom shell 2 as an integral structure. The side of the bottom shell 2 is provided with a plurality of buckles (not shown), and the function of the buckles is to make the bottom shell 2 stable after being embedded in the cabinet countertop, especially when the mounting hole provided on the countertop is larger than the designed mounting hole, the elasticity of the buckles can be used to prevent the electromagnetic cooker from sliding forward, backward, left and right. The side wall of the bottom shell 2 facing the user is provided with an exhaust port 21, which is used to discharge the hot air generated during the heat dissipation process. A vent (not shown) is formed on the bottom wall of the bottom shell 2, and the vent is directly opposite to the air inlet (not shown) of the fan assembly 5. When the fan assembly 5 is running, the air outside the bottom shell 2 is sucked in from the vent, and is discharged from the exhaust port 21 after passing through the heat exchanger for heat exchange.

[0046] It is understandable that a suitable number of air vents can be provided on the side walls on the left and right sides of the bottom shell 2 for exhaust. In addition, to prevent foreign objects such as mosquitoes from entering, the air vents and the air vents 21 are both configured as a grid structure.

[0047] like Figure 2 As shown in Figure 2 The schematic diagram shows the structure of the internal components of the bottom shell 2 after the microcrystalline glass panel 1 is removed. The induction cooker provided in this embodiment is provided with four heating units 3, each of which includes an aluminum tray 32, a coil disk (not shown), a mica sheet 31, an NTC thermistor 33, etc. The coil disk generates eddy currents through an inverter after being powered on to heat the cookware. Mica sheets 31 are provided above and below the coil disk, and the mica sheets 31 play a role in heat insulation and heat preservation. When the installation is completed, the mica sheet 31 and the coil disk are both located in the space between the aluminum tray 32 and the microcrystalline glass panel 1. In this embodiment, each aluminum tray 32 supports two heating units 3. Figure 3 As shown in the figure, a plurality of support columns 22 are arranged on the bottom shell 2, and the aluminum tray 32 is installed to the bottom shell 2 through the plurality of support columns 22. Usually, one aluminum tray 32 is supported by four support columns 22. When the size of the aluminum tray 32 is larger, the number of support columns 22 can be appropriately increased.

[0048] Furthermore, in order to ensure that the glass-ceramic panel 1 can reliably contact the NTC thermistor 33 after installation to ensure the bottom temperature test of the pot, each support column 22 of this embodiment is also provided with an elastic member, and the elastic member in this embodiment is a spring 7, such as Figure 3As shown in the figure, only the spring 7 on one of the support columns 22 is illustrated. In the installed state, the top end of each spring 7 abuts against the lower bottom surface of the aluminum tray 32, and the bottom end abuts against the step surface formed on the support column 22. After installation, the spring 7 has a certain amount of pre-compression. After the microcrystalline glass panel 1 is covered on the top of the bottom shell 2, the aluminum tray 32 and the components above it have a tendency to move upward under the restoring force of the spring 7, so that the NTC thermistor 33 can be pressed against the microcrystalline glass panel 1 to ensure the temperature measurement performance.

[0049] It should be noted that, although the present embodiment is described by taking four heating units 3 as an example, this is not restrictive, and the number of heating units 3 can also be any suitable value such as 2, 3, 5, 6, etc. In addition, the present embodiment is described by taking one aluminum tray 32 supporting two heating units 3 as an example, and it can be understood that one aluminum tray 32 can also support one heating unit 3, three heating units 3, etc., and can be adaptively adjusted according to actual needs and internal space, and these similar embodiments should all be included in the protection scope of the present utility model.

[0050] Continue to refer Figure 2 As shown, a display panel 8 is installed on the side of the bottom shell 2 close to the user, and the display panel 8 is used to display information such as program, time, temperature, etc.

[0051] like Figure 3 As shown in , the bottom shell 2 is also provided with an electric control board group 5, a radiator group 4, a fan assembly 5, etc. The electric control board group 5 in this embodiment includes a first electric control board 61 and a second electric control board 62, and the first electric control board 61 and the second electric control board 62 are installed side by side on the bottom wall of the bottom shell 2. Two heating units 3 are arranged above the first electric control board 61, and the first electric control board 61 is used to control the operation of the two heating units 3. Two heating units 3 are arranged above the second electric control board 62, and the second electric control board 62 is used to control the operation of the two heating units 3. The power of each heating unit 3 can be the same or different, and the heating units 3 above each electric control board can operate independently or in coordination. The first electric control board 61 and the second electric control board 62 are fixedly installed to the bottom shell 2 by limit hooks (not marked) and fasteners. Components such as transformers, capacitors, resistors, etc. are arranged on each electric control board.

[0052] In this embodiment, the first electric control board 61 is fixedly mounted with the first radiator 41, and the second electric control board 62 is fixedly mounted with the second radiator 42. The first radiator 41 and the second radiator 42 are arranged adjacent to each other and are located between the first electric control board 61 and the second electric control board 62. Figure 3 and Figure 4As shown in the figure, since the first radiator 41 and the second radiator 42 in this embodiment have the same structure and the same installation method, for the convenience of observation, only the structure of the second radiator 42 is shown in the figure. It can be understood that the first radiator 41 and the second radiator 42 can also be slightly different. Figure 4 As shown in , the second radiator 42 is fastened to the second electric control board 62 by fasteners while being clamped. The second radiator 42 is provided with a plurality of fins for increasing the heat exchange area, and there is a gap between the bottom and the second electric control board 62. The side portion is constructed as an inclined surface structure, and a plurality of heat dissipation holes 421 are correspondingly provided. The heat dissipation holes 421 are connected to the gap at the bottom, so that cold air can flow out from the side of the second radiator 42. In this embodiment, some power devices of the electromagnetic cooker, such as inverters, rectifier bridges, IGBT (Insulate-Gate Bipolar Transistor) components, etc., are installed on the inclined surface structure of the first radiator 41 and the second radiator 42 to improve the heat dissipation efficiency of these power devices with large heat generation. It can be understood that the situation of the first radiator 41 installed on the first electric control board 61 is the same, and it will not be repeated here.

[0053] like Figure 5 As shown in the figure, the fan assembly 5 of the electromagnetic cooker of the utility model is used to promote the air circulation in the bottom shell 2, so as to take away the heat dissipated by the electric control board and the like with the help of the circulating air, so as to achieve the purpose of heat dissipation. The fan assembly 5 in this embodiment includes a volute 51 and a wind wheel 52 arranged in the volute 51, and the air inlet (not shown) of the volute 51 faces the bottom wall of the bottom shell 2 and is directly opposite to the vent formed in the bottom shell 2. The volute 51 is fixedly mounted on the bottom wall of the bottom shell 2 by fasteners and buckles, and the air outlet 511 of the fan assembly 5 faces the radiator group 4 so that the wind can blow directly to the radiator group 4.

[0054] In the embodiment of the utility model, a plate assembly 23 is also provided on the bottom shell 2, and the plate assembly 23 includes a guide plate 232 and a diverter plate 231. The guide plate 232 is used to guide the air outlet of the fan assembly 5 to blow toward the radiator group 4, and the diverter plate 231 is used to divert the air outlet of the fan assembly 5 so that the air outlet flows evenly to different radiators. Figure 5 As shown in , the guide plate 232 in this embodiment is a plate-shaped structure extending vertically upward from the bottom wall of the bottom shell 2. One vertical edge of the guide plate 232 is arranged close to the side of the air outlet 511, and the other vertical edge is close to the radiator group 4, so that the air outlet of the air outlet 511 can be guided by the guide plate 232 to blow directly to the radiator group 4 as much as possible. Figure 5 As shown in , the two vertical side edges of the guide plate 232 are provided with a curved surface structure to reduce eddy currents, which is beneficial to reducing wind noise.

[0055] In the embodiment of the utility model, the diverter plate 231 is a plate-shaped structure extending vertically upward from the bottom wall of the bottom shell 2, one end of the diverter plate 231 is directly opposite to the air outlet 511, and the other end of the diverter plate 231 extends from the side of the radiator group 4 close to the air outlet 511 to the side of the radiator group 4 away from the air outlet 511. Figure 4 As shown in , a portion of the splitter plate 231 is placed between the first radiator 41 and the second radiator 42. In this way, the splitter plate 231 can also play a positioning role during the installation process. Figure 5 As shown in , the air outlet 511 of the fan assembly 5 can flow to the first radiator 41 and the second radiator 42 respectively under the joint guidance of the guide plate 232 and the diverter plate 231, and the air volume on both sides of the diverter plate 231 is basically the same, so that one fan assembly 5 can cool two electronic control boards at the same time, and the heat dissipation effect of each electronic control board is equivalent, which not only reduces the overall cost of the induction cooker and simplifies its internal structure, but also ensures a good heat dissipation effect.

[0056] The flow divider 231 and the flow guide plate 232 in this embodiment are integrally formed with the bottom shell 2. It is understandable that the flow divider 231 and the flow guide plate 232 can also be connected into an integral structure by bonding, clamping, etc. In addition, the structure of the flow divider 231 can also be not extended to the other end of the radiator group 4, but only retain the part facing the air outlet 511 of the fan assembly 5.

[0057] So far, the technical solution of the present invention has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
