Detailed Implementation

[0022] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0023] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0024] As described in the background section, existing commercial electric ovens rely heavily on manual service from service personnel, which takes up their working time.

[0025] Therefore, this application provides an intelligent electric oven, including an oven body 10, an oven body 10 with a grill rack 11 for placing food; a heater 12 connected to the oven body 10 for heating the food placed on the grill rack 11; and a camera device 20 mounted on the oven body 10 for capturing images of the food on the grill rack 11.

[0026] like Figure 1 , Figure 2 As shown, the oven body 10 of this application embodiment can adopt a cabinet structure or a frame structure. For example, the oven body 10 can be assembled from support rods and plates to form an operating space, storage space, or installation space. In addition, the oven body 10 can be equipped with devices such as a power supply, lighting, fan, or exhaust system.

[0027] The grill rack 11 can be configured as an interlocking structure, such as a slot, so that the end of a barbecue skewer with food inserted can be inserted into the slot of the grill rack 11. Alternatively, the grill rack 11 can be configured as a mesh structure to hold the food to be grilled. The grill rack 11 can also be configured as an inserting or clamping structure, so that the food to be grilled can be skewered on or clamped on the grill rack 11. The oven body 10 can have a single-layer grill rack 11 or two or more layers of grill racks 11. The grill rack 11 can include a frame and a drive device. A food support frame can be placed on the frame to fix the food. The drive device can drive the frame to move, and the frame can drive the food support frame to rotate; or the drive device can directly drive the food support frame on the frame to rotate.

[0028] In this embodiment, ingredients are placed directly on the frame, skewered into grill skewers, or clamped onto the frame using an ingredient support frame. The driving device is a reciprocating drive mechanism connected to the frame, which drives the ingredients to reciprocate within the heating range formed by the heater 12 and the reflector 17 to ensure uniform heating. Alternatively, the driving device is a rotary drive mechanism connected to the grill skewers or other ingredient support frames that can rotate on the frame to rotate the grill skewers or ingredients on the support frames to ensure uniform heating.

[0029] The heater 12 can be configured to be connected to a power source to convert electrical energy into heat energy to heat food placed on the grill 11. For example, the heater 12 may include heating wires or heating tubes to convert electrical energy into heat energy and heat the food by means of thermal radiation. In some other embodiments, the heater 12 may also be configured to use the combustion of flammable gases such as liquefied petroleum gas and natural gas to heat the food placed on the grill 11.

[0030] The camera device 20 is installed on the oven body 10 and is used to photograph and image the food on the grill 11.

[0031] The intelligent electric oven 100 is equipped with a camera device 20, which helps to provide reference guidance for better use of the intelligent electric oven 100. For example, the camera device 20 can be further equipped with a display panel, which can monitor the baking status of the food on the grill 11 in real time based on the monitoring images on the display panel, and send a prompt message to the user after the food is cooked, reminding the customer to eat it.

[0032] In addition, the imaging information of the food on the grill 11 by the camera device 20, such as whether there is food on the grill 11, or the difference in shape and color between uncooked and cooked food, can be used to control the heater 12, the ventilation system, etc., to improve the intelligence level of the smart electric oven 100 and enhance the user experience.

[0033] However, as the core component of image recognition technology, the camera device is prone to problems such as image sensor performance degradation, accelerated aging of circuit components, and even system crashes and increased image noise when working in high-temperature environments.

[0034] Traditional solutions typically employ components made of highly thermally conductive materials (such as metal heat sinks and heat pipes) or active cooling methods (such as fan cooling and semiconductor cooling) to address the heat dissipation problem of camera devices. However, these methods are costly and may increase the size and power consumption of the camera device, making them unsuitable for devices or applications where cost and form factor are highly sensitive, such as electric ovens.

[0035] To address the aforementioned issues, optionally, the camera device of this application is equipped with a filter, which is used to filter out infrared light and / or heat energy radiated to the camera device by the heater during heating.

[0036] Since the heat radiation from the heater 12 to the food includes visible light and infrared light with longer wavelengths, in order to reduce the heat radiation generated by the heater 12 to the camera device 20, a filter 21 that can filter infrared light can be configured along the imaging optical path of the camera device 20. This can reduce the infrared light and / or heat energy entering along the imaging optical path, which is beneficial to reducing the thermal effect of infrared light on the camera device 20, thereby helping to lower the temperature of the camera device 20, avoiding thermal damage to the imaging element of the camera device 20, and avoiding problems such as performance degradation of the image sensor 24, accelerated aging of circuit components, system crashes, and increased image noise caused by excessive temperature of the camera device 20. The filter 21 can be made of glass, which is low in cost and not easily affected by the thermal radiation of infrared light. For example, an IR 650nm filter 21 can be used. This filter 21 is a short-pass filter, also known as a low-pass filter. Light shorter than the selected wavelength passes through, while light longer than the selected wavelength is blocked. It can be made by vacuum coating of optical glass and has the characteristics of high transmittance, wide cutoff band and good film strength. The center wavelength of transmittance is 650±5nm, the transmittance band is 410-640nm, and the cutoff band is 670-1100nm, so that the transmittance of visible light band reaches more than 90%, while the infrared light band is filtered out. Thus, without affecting the imaging of the camera device 20, the infrared light that is likely to cause the temperature of the camera device 20 to rise is effectively filtered out.

[0037] In addition, the filter 21 can filter out the strong red light in the thermal infrared radiation environment, reduce the interference components in the incident light of the camera device 20, improve the fidelity and realism of the images captured by the camera device 20, make the optical imaging of the camera device 20 clearer and more accurate, and improve the imaging effect, thereby improving the image recognition accuracy.

[0038] The intelligent electric oven 100 provided in the embodiments of this application includes: an oven body 10, a heater 12, and a camera device 20; the oven body 10 is provided with a grill rack 11 for placing food, and the heater 12 is connected to the oven body 10 to heat the food placed on the grill rack 11; the camera device 20 is mounted on the oven body 10 for capturing images of the food on the grill rack 11, wherein the camera device 20 is equipped with a filter 21 for filtering infrared light and / or heat energy radiated to the camera device 20 by the heater 12 during heating. The intelligent electric oven 100 with camera device 20 provided in this application has a camera device 20 The camera device 20 can identify the status of the food on the smart electric oven 100, thereby automatically controlling the operation of the smart electric oven 100 and realizing the intelligent control of the smart electric oven 100. In addition, the filter 21 on the camera device 20 can reduce the impact of infrared photothermal effect on the camera device 20, thereby effectively reducing the temperature of the camera device 20, so that the camera device 20 can work normally when the smart electric oven 100 is running, improving the life of the camera device 20 and reducing costs. Furthermore, the filter 21 can filter the strong red light entering the camera device 20, thereby improving the imaging effect of the camera device 20 and improving the accuracy of image recognition.

[0039] Optionally, in one embodiment of this application, such as Figure 1 , Figure 2 As shown, the heater 12 and the camera device 20 are located above the grill 11 so that the camera device can capture images of the food on the grill and the heater can properly grill each food item on the grill.

[0040] Furthermore, by positioning the heater 12 and the camera device 20 above the grill 11, when the food is being grilled, the heater 12 and the camera device 20 are positioned above the food. This avoids the impact on the heater 12 and the camera device 20 during the heating process when the heater 12 is located to the side or below the grill 11, or the impact on the heater 12 and the camera device 20 caused by food dripping oil.

[0041] Optionally, in this embodiment, the height of the camera device 20 is not lower than the height of the heater 11. When the camera device 20 and the heater 12 are arranged opposite each other, the angle between the camera device 20's shooting direction toward the food on the grill 11 and the heater 12's heat radiation direction toward the food on the grill 11 may be large. This will result in more infrared light entering the camera device 20 along the imaging light path. Therefore, in this embodiment, the camera device 20 and the heater 12 can be arranged on the same side of the oven body 10. For example, the camera device 20 and the heater 12 can be arranged on the upper side of the oven body 10, and the height of the camera device 20 is not lower than the height of the heater 11. The heater 12 heats the food on the grill 11 located below, and the camera device 20 shoots the food on the grill 11 located below. In this way, the angle between the camera device 20's shooting direction toward the food on the grill 11 and the heater 12's heat radiation direction toward the food on the grill 11 is small, which helps to reduce the infrared light entering the camera device 20 along the imaging light path.

[0042] Optionally, in one embodiment of this application, such as Figures 3-5 As shown, the camera device 20 includes a protective cover 22, which has a light inlet 220, and the filter 21 includes a first filter 211 disposed in the light inlet 220.

[0043] The camera device 20 is equipped with a protective cover 22, which helps to protect the imaging component housed within the protective cover 22. For example, the camera device 20 can be mounted and fixed to the oven body 10, with the protective cover 22 and the oven body 10 together forming a cavity. Alternatively, the protective cover 22 can form a cavity alone, so that the imaging component of the camera device 20 is enclosed within the cavity. External light enters the camera device 20 through the light inlet 220 of the protective cover 22 to form an image. In this way, by setting a first filter 211 in the light inlet 220, the infrared light entering from the light inlet 220 is filtered out, and the visible light used for imaging passes through the first filter 211 into the interior of the camera device 20, thereby preventing the infrared light from entering the camera device 20 and causing an increase in temperature.

[0044] The protective cover 22 can be made of plastic or sheet metal and has good high temperature resistance. The protective cover 22 can be made of non-transparent material to prevent visible light or infrared light from passing through the protective cover 22 and interfering with the imaging of the camera device 20 or affecting the temperature of the camera device 20.

[0045] To further improve the filtering effect on infrared light, optionally, in one embodiment of this application, such as Figure 6 , Figure 7As shown, filter 21 includes a second filter 212; the second filter 212 is disposed between the lens 23 of the imaging device 20 and the image sensor 24 of the imaging device 20. The lens 23 may include multiple lenses, such as convex lenses or concave lenses, to perform optical imaging of transmitted light. The image sensor 24 can utilize the photoelectric conversion function of an optoelectronic device to convert the optical imaging of the lens 23 into an electrical signal, for example, it can be made of CCD (Charge-coupled Device) or CMOS (Complementary Metal-Oxide-Semiconductor).

[0046] After a first filter 211 is provided at the light inlet 220 of the protective cover 22 to form a first filtering barrier for infrared light, this embodiment further provides a second filter 212 in the imaging optical path of the imaging device 20, that is, between the lens 23 and the image sensor 24, thereby forming a second filtering barrier for infrared light. Thus, infrared light not filtered by the first filter 211 at the light inlet 220 passes through the lens 23 along the imaging optical path and is filtered again by the second filter 212 between the lens 23 and the image sensor 24 before reaching the image sensor 24. It can be understood that after the double filtering by the first filter 211 and the second filter 212, most of the infrared light entering along the imaging optical path of the imaging device 20 is filtered out, thereby further improving the filtering effect of infrared light, avoiding the thermal effect of infrared light on the imaging device 20, reducing the temperature of the imaging device 20 in high-temperature environments, and improving the reliability of image recognition.

[0047] Moreover, the first filter 211 and the second filter 212 can filter out invisible infrared light and visible strong red light in the incident light of the camera device 20, which helps to reduce interference light in the optical imaging system of the camera device 20, improve color reproduction, and make the imaging of the camera device 20 clearer and better, thereby improving the accuracy and reliability of image recognition.

[0048] In high-temperature environments, excessive thermal deformation of the components of lens 23 can easily cause abnormal phenomena such as blurred images, color distortion, and increased noise. To solve this problem, optionally, in one embodiment of this application, such as... Figure 6 As shown, the lens 23 includes a metal lens barrel 231 and multiple glass lenses 232, with the glass lenses 232 embedded within the metal lens barrel 231. The use of a metal lens barrel 231 and glass lenses 232 in the lens 23 improves its high-temperature resistance, reduces thermal deformation of its components, and ensures the imaging quality and operational reliability of the imaging device 20 in high-temperature environments.

[0049] Optionally, in one embodiment of this application, such as Figure 2 , Figure 8 As shown, the oven body 10 is provided with a first mounting plate 13, and the camera device 20 is connected to the first mounting plate 13, and / or, the oven body is provided with a second mounting plate 15, and the camera device is connected to the second mounting plate.

[0050] The camera device 20 can be fixed to the oven body via the first mounting plate 13 to facilitate the fixation of the camera device 20. Optionally, to facilitate imaging, the first mounting plate 13 and the second mounting plate 15 can be respectively provided on both sides of the oven body, so that at least one camera device can be connected to both sides of the oven body, thereby capturing images of the food on the grill from different angles on both sides, improving the imaging effect and the accuracy of image recognition.

[0051] Optionally, in one embodiment of this application, such as Figure 2 , Figure 8 As shown, the circuit board 25 of the camera device 20 is arranged adjacent to the first mounting plate 13, and a heat conductor is provided between the circuit board 25 and the first mounting plate 13, and / or the circuit board 25 of the camera device 20 is arranged adjacent to the second mounting plate 15 and a heat conductor is provided between the circuit board 25 and the second mounting plate 15.

[0052] The circuit board 25 of the camera device 20 can be used to configure electrical components such as an image processor to process the captured images, or to be electrically connected to an interactive module for user operation and control. Electrical connections can include direct electrical connections, indirect electrical connections, wired electrical connections, wireless connections, etc. Since the circuit board 25 or the image processor often generates a large amount of heat during operation, in this embodiment, the oven body 10 is provided with a first mounting plate 13 and / or a second mounting plate 15. For example, the first mounting plate 13 and / or the second mounting plate 15 can be made of sheet metal or other metal structures with a large heat dissipation area to facilitate heat transfer between the first mounting plate 13 and / or the second mounting plate 15 and the surrounding environment, thereby maintaining a lower temperature for the first mounting plate 13 and / or the second mounting plate 15. The circuit board 25 of the camera device is disposed adjacent to the first mounting plate 13 and / or the second mounting plate 15. For example, the circuit board 25 is in contact with the first mounting plate 13 and / or the second mounting plate 15, which also facilitates heat transfer between the circuit board 25 and the first mounting plate 13 and / or the second mounting plate 15. The heat generated by the circuit board 25 can be quickly conducted to the first mounting plate 13 and / or the second mounting plate 15, and then conducted to the surrounding environment by the first mounting plate 13 and / or the second mounting plate 15.

[0053] Because the image processor is small in size but generates a lot of heat, in order to better dissipate heat from the image processor, in this embodiment, a heat conductor is provided between the circuit board 25 and the first mounting plate 13 and / or the second mounting plate 15, and / or between the circuit board 25 and the second mounting plate 15. For example, a heat conductor is provided between the image processor of the circuit board 25 and the first mounting plate 13 and / or the second mounting plate 15. The heat conductor can be a high thermal conductivity silicone pad, etc., to ensure efficient heat transfer between the image processor and the first mounting plate 13 and / or the second mounting plate 15, so that the heat generated by the image processor under high temperature environment or high load operation can be dissipated in time, avoiding performance impact, thereby improving the reliability of image recognition and image processing of the camera device 20.

[0054] Optionally, in one embodiment of this application, such as Figure 2 As shown, a first interactive module 14 is provided on the first mounting plate 13. The first interactive module 14 is electrically connected to the camera device 20 to provide information to the user. In this embodiment, the first interactive module 14 can be configured to have a display function. For example, the first interactive module 14 can be configured with a display panel or indicator lights. After the camera device 20 takes an image of the food on the grill 11, the image processor can identify and judge the image captured by the camera device 20 based on a preset image recognition algorithm. For example, it can determine whether there is food on the grill 11 and whether the food on the grill 11 is cooked. For grills with multiple placement positions... The rack 11 is used to determine whether food is placed in each position and whether the food is cooked. The first interaction module 14 can be electrically connected to the image processor of the camera device 20. Based on the image recognition results, the results can be displayed on the indicator lights or display panel of the first interaction module 14. For example, the first interaction module 14 can be configured with multiple indicator lights, each corresponding to one of the positions on the rack 11, and can display multiple colors. This can show whether food is placed in the corresponding position or whether the food is cooked, allowing users to understand the baking status of the smart electric oven 100 in a timely and intuitive manner. Depending on the usage environment of the smart electric oven 100, the first mounting plate 13 and the first interaction module 14 can be set on one side of the oven body 10, such as the left side of the oven body 10.

[0055] To further facilitate user observation of the baking process in the intelligent electric oven 100, optionally, in one embodiment of this application, such as Figure 2As shown, the oven body 10 also includes a second mounting plate 15, on which a second interactive module 16 is mounted. The second interactive module 16 is electrically connected to the camera device 20 to provide information to the user. The second mounting plate 15 may use the same structure or material as the first mounting plate 13, such as sheet metal, and the second interactive module 16 may have the same function and configuration as the first interactive module 14. The second mounting plate 15 and the second interactive module 16 may be located on the opposite side of the oven body 10 relative to the first interactive module 14, for example, on the right side of the oven body 10. In this way, the user can observe the baking status of the smart electric oven 100 from the left side of the oven body 10 by observing the first interactive module 14, and can also observe the baking status of the smart electric oven 100 from the right side of the oven body 10 by observing the second interactive module 16.

[0056] As can be seen, by setting the first interaction module 14 and the second interaction module 16 on both sides of the smart electric oven 100, users sitting on both sides of the smart electric oven 100 can observe the corresponding prompt information, thereby improving the user experience.

[0057] In other embodiments, the first interaction module 14 and the second interaction module 16 may also be configured to have control functions. The camera device 20, heater 12, and grill 11 are electrically connected to the first interaction module 14 and the second interaction module 16 to realize the control functions. For example, the first interaction module 14 may be electrically connected to the camera device 20, and the camera device 20 may be set or operated using the first interaction module 14 to control the shooting of the camera device 20; or, the first interaction module 14 may also be electrically connected to the heater 12, and the heater 12 may be turned on or off or its power may be controlled using the first interaction module 14; or, the first interaction module 14 may also be electrically connected to the grill 11, and for the grill 11 equipped with a drive device, the drive device of the grill 11 may be controlled using the first interaction module 14 to make the grill 11 rotate or one of its placement positions rotate; in addition, the first interaction module 14 may also be electrically connected to devices such as power supply, lighting, fan, or ventilation system to control these devices.

[0058] The first interactive module 14 can use mechanical buttons, allowing users to control the interaction by pressing the mechanical buttons. Alternatively, the first interactive module 14 can also use a display panel, allowing users to control the interaction by pressing or touching the display panel.

[0059] Furthermore, the first interaction module 14 and the second interaction module 16 can also be configured to be electrically connected to different components, allowing the first interaction module 14 and the second interaction module 16 to control different components or display the working status of different components. For example, the first interaction module 14 can be electrically connected to only a few components, such as only to the camera device 20, and the circuit board 25 of the camera device 20 can be arranged adjacent to the first mounting plate 13, so that the heat generated by the circuit board 25 of the camera device 20 is dissipated through the first mounting plate 13, and the first interaction module 14 can be used to control the camera device 20; the second interaction module 16 can be electrically connected to other components, such as the heater 12, and the circuit board of the heater 12 can be arranged adjacent to the second mounting plate 15, so that the heat generated by the circuit board of the heater 12 is dissipated through the second mounting plate 15, and the second interaction module 16 can be used to control the heater 12. This avoids integrating the circuit boards of multiple components on the first mounting plate 13 at the same time, which would cause a large heat dissipation load on the first mounting plate 13, and also avoids signal interference between different circuit boards.

[0060] It is understandable that by setting up multiple mounting plates and interactive modules, users can not only easily understand the baking situation from multiple positions of the smart electric oven 100, but also install and configure multiple different components separately, which helps to improve the heat dissipation effect and working reliability of each component, such as the camera device 20.

[0061] Optionally, in one embodiment of this application, such as Figure 2 As shown, the intelligent electric oven 100 is also provided with a reflector 17, which at least partially surrounds the heater 12 and at least partially shields the heater 12 and the camera device 20.

[0062] The reflector 17 is used to reflect the heat generated by the heater 12 toward the food on the grill 11 to concentrate the heat. The reflector 17 can be made of metal, such as aluminum foil. In this embodiment, the reflector 17 can be configured to partially surround the heater 12 according to the shape of the heater 12, so that the heat radiation generated by the heater 12 is conducted along a predetermined direction, such as toward the food on the grill 11, thereby improving heating efficiency and energy utilization efficiency.

[0063] Furthermore, in this embodiment, the reflector 17 at least partially shields the space between the heater 12 and the camera device 20. For example, in this embodiment, the camera device 20 and the heater 12 are arranged adjacent to each other on the upper side of the oven body 10, and the grill 11 is located below the heater 12. The reflector 17 partially surrounds the heater 12, so that the heater 12 can only directly radiate heat to the food on the grill 11 below. The reflector 17 facilitates the shielding between the heater 12 and the camera device 20, which can prevent the infrared light of the heater 12 from directly hitting the camera device 20, reduce the amount of infrared light entering the light inlet 220, and thus help reduce the impact of infrared photothermal effect on the camera device 20.

[0064] Optionally, in one embodiment of this application, such as Figure 1 , Figure 2 As shown, the grill 11 has multiple placement positions suitable for placing food. The intelligent electric oven 100 is equipped with at least one camera device 20, and each placement position is located within the field of view of at least one camera device 20. To improve the working efficiency of the intelligent electric oven 100, the grill 11 is configured with multiple placement positions. To ensure clear imaging of the food in each placement position, at least one camera device 20 can be configured, for example, two or more camera devices 20. This avoids the situation where, with only a single camera device 20, food placed at the edge of the field of view of that single camera device 20 suffers from low image quality or inaccurate image recognition due to lens distortion and optical aberration. It can be understood that in this embodiment, by configuring at least one camera device 20 and ensuring that each placement position is located within the field of view of at least one camera device 20, for example… Figure 9 , Figure 10 As shown, for a grill 11 with 16 placement positions, two camera devices 20 can be configured, such that the field of view of each camera device 20 covers at least 8 placement positions. The field of view of each camera device 20 can specifically include a longitudinal field of view A along the height direction of the placement position and a lateral field of view B along the arrangement direction of the placement positions. The longitudinal field of view A and the lateral field of view B of each camera device 20 cover at least 8 placement positions. This can ensure the imaging quality of the food in the corresponding placement position by each camera device 20, which is beneficial to improving the reliability and accuracy of image recognition.

[0065] Optionally, in one embodiment of this application, such as Figure 11As shown, the heater 12 includes at least a first heating section 121 and a second heating section 122 capable of independent heating. The first heating section 121 and the second heating section 122 are respectively used to heat the target placement position among the multiple placement positions of the grill. Depending on the arrangement of the placement positions of the grill 11, the heater 12 may have a tubular structure or a rod-shaped structure to effectively and fully heat each placement position along the arrangement direction of the placement positions. At the same time, in order to improve heat utilization and avoid energy waste, the heater 12 may be configured to include two or more heating sections capable of independent heating, for example, at least a first heating section 121 and a second heating section 122 capable of independent heating, with the first heating section 121 and the second heating section 122 respectively used to heat the target placement position among the multiple placement positions.

[0066] For example, in this embodiment, the grill 11 has 16 placement positions. Therefore, the first heating section 121 can be configured to heat the target placement positions numbered 1-8, and the second heating section 122 can be configured to heat the target placement positions numbered 9-16. In this way, when food is placed in the placement positions numbered 1-8, only the first heating section 121 needs to be turned on, and the second heating section 122 does not need to be turned on. When food is placed in the placement positions numbered 9-16, only the second heating section 122 needs to be turned on, and the first heating section 121 does not need to be turned on, so as to avoid energy waste.

[0067] It should be noted that the first heating section 121 and the second heating section 122 are used to heat the target placement positions among the multiple placement positions. Depending on the specific application, the target placement position can be a part of the multiple placement positions or all of the multiple placement positions. Moreover, the first heating section 121 and the second heating section 122 can be configured with the same shape, size, heating power, heating method, etc., or they can be configured with different shapes, sizes, heating power, heating methods, etc. For example, for a grill 11 with 16 placement positions, the first heating section 121 can be configured to heat the target placement positions numbered 1-16 with a first power, such as the heat preservation power, and the second heating section 122 can be configured to heat the target placement positions numbered 1-16 with a second power, such as the baking power.

[0068] Optionally, in one embodiment of this application, the heater 12 is further provided with a control module, which is configured to control the opening and closing and / or power of the first heating section 121 and the second heating section 122 based on the imaging information of the food on the grill 11 obtained by the camera device 20.

[0069] Since the presence or absence of food on the grill 11, or the shape and color of the food at different baking stages, often vary, the imaging information generated by the camera device 20 also often differs. Therefore, based on image recognition algorithms, the images captured by the camera device 20 can be identified and judged to make corresponding heating control decisions. For example, in this embodiment, the intelligent electric oven 100 has 16 placement positions on the grill 11. If, based on the imaging information from the camera device 20, it is determined that positions numbered 1-8 have food placed on them, while positions numbered 9-16 do not, the first heating section 121 can be turned on and the second heating section 122 can be turned off. If, based on the imaging information from the camera device 20, it is determined that the food placed in positions numbered 1-8 is cooked, the first heating section 121 can be turned off.

[0070] In addition, the first heating section 121 and the second heating section 122 can be configured with adjustable power heating methods. For example, frequency conversion control can be used to adjust the power of each heating section of the heater 12. For example, if the imaging information from the camera device 20 determines that food is placed in positions 1-8 and is not fully cooked, the power supply frequency of the first heating section 121 can be controlled so that the first heating section 121 heats the food at maximum heating power; if the imaging information from the camera device 20 determines that the food placed in positions 1-8 is fully cooked, the power supply frequency of the first heating section 121 can be controlled so that the first heating section 121 heats the food at heat preservation power, or the first heating section 121 can be turned off.

[0071] It is evident that the control strategy based on the control module can improve the intelligence level of the intelligent electric oven 100, reduce heat energy waste, and help avoid components such as the camera device 20 being in a high-temperature environment for a long time, thereby improving the service life and reliability of the components.

[0072] Optionally, in one embodiment of this application, the oven body 10 further includes a support frame, which includes a column 18 and a lateral extension 19 connected to the column 18, the lateral extension 19 extending above the grill rack 11; a first mounting plate 13 is provided on the lateral extension 19, and a camera device 20 is connected to the first mounting plate 13. The support frame can form a support structure for the oven body 10, and the support frame includes a column 18 and a lateral extension 19 connected to the column 18, the lateral extension 19 extending above the grill rack 11, thus forming a grilling space in the middle of the oven body 10 that is convenient for user operation; moreover, the first mounting plate 13 is provided on the lateral extension 19, and the camera device 20 is connected to the first mounting plate 13, thereby forming an installation position for the camera device 20 above the oven body 10, which facilitates imaging of food from above the grill rack 11, helps to reduce infrared light entering the camera device 20 along the imaging light path, and also helps to avoid accidental contact or interference with the camera device 20 during the food grilling process. The oven body is also equipped with a first interactive module 14 to provide information to the user. A first mounting plate 13 is provided on the lateral extension 19. The first interactive module and the camera device 20 are both connected to the first mounting plate 13. Alternatively, the oven body is also equipped with a second interactive module to provide information to the user. A second mounting plate is provided on the lateral extension. The second interactive module and the camera device 20 are both connected to the second mounting plate. By setting the first interactive module 14 and / or the second interactive module 15 on the oven body, it is easier for the user to recognize the prompts issued by the electric oven, thus improving the user experience.
