DETAILED DESCRIPTION

[0039] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0040] With the continuous development of intelligent cooking technology, users' demand for visualization and intelligent control of the cooking process is increasing, which promotes the innovative application of cameras in steam ovens. At present, more and more intelligent steam ovens integrate cameras inside the cabinet door to realize real-time monitoring of the heating, roasting or steaming process of food without opening the oven door. This design not only avoids temperature fluctuations and energy losses caused by frequent opening of the door, but also analyzes the color and shape changes of food through image recognition technology, assisting in realizing intelligent functions such as automatic recognition of dishes, judgment of maturity, and recommendation of cooking modes.

[0041] However, the current camera technology applied in steam ovens still has obvious limitations. Most products use fixed installation structure, which makes the shooting angle and height of the camera cannot be adjusted. This static design limits the lens field of view and can only cover a fixed area inside the cavity. Users often need to manually adjust the placement of food in the baking tray or choose a specific shelf to ensure that the food is within the effective shooting range of the camera, which not only increases the operation complexity, but also affects the convenience of use. Especially when cooking multiple layers, since it is impossible to clearly image food at different heights at the same time, the cooking system cannot accurately identify the color change, shape evolution and other maturity characteristics of food at different layers, which leads to a decrease in the judgment accuracy of intelligent recognition algorithms and affects the reliability of intelligent functions such as automatic temperature control and automatic shutdown. In addition, single-angle image acquisition cannot fully reflect the overall heating condition of food, and lacks multi-angle and three-dimensional visual information support, limiting the deep application of image recognition technology in cooking process monitoring.

[0042] One of the core ideas of the embodiments of the present application is to set a light guide structure that can move up and down inside the cabinet door, driven by a vertical motion assembly, so that the shooting assembly can shoot food at different heights, improving the imaging effect.

[0043] Reference Figure 1 A structure block diagram of a cooking device according to an embodiment of the present application is shown. The cooking device 1 comprises:

[0044] a cooking cavity (not shown in the figure); a cabinet door 11 having an inner wall and an outer wall separated by a gap;

[0045] Exemplarily, the cooking device 1 can be a steam oven, and the cooking cavity is the core functional area of the device, used to contain food and realize multiple cooking modes such as heating, steaming, baking, etc., and the sealing performance and temperature control accuracy directly affect the cooking effect. The cabinet door 11 as the sealing structure of the cooking cavity can include an inner wall and an outer wall to form a double-layer or multi-layer structure with a gap between the inner wall and the outer wall, so as to realize effective heat insulation and heat preservation functions. Moreover, this structure effectively reduces the surface temperature of the outer wall of the cabinet door, avoids the user from being scalded by touching the high-temperature surface during operation or cleaning, and improves the safety level of the product. In addition, under the high-temperature operating environment, the gap between the inner wall and the outer wall can also play a role in buffering thermal stress, reducing the risk of glass deformation or breakage caused by sudden temperature changes, and enhancing the structural stability and durability of the cabinet door. For the intelligent steam oven integrated with a camera, a lighting lamp or a sensor, the heat management of the internal space of the cabinet door is particularly important, and the double-layer wall structure provides a relatively mild installation environment for these electronic components, which helps to prolong their service life. At the same time, the gap structure can also cooperate with the sealing strip and the anti-condensation design to prevent water vapor from condensing between the glass layers, maintain the visual transparency, and facilitate the user to observe the cooking process.

[0046] The light guide structure 111 arranged inside the cabinet door 11 includes a lens 1111 inclined downward toward the cooking cavity, used to reflect the image in the cooking cavity;

[0047] Referring to Figure 2 , another structure diagram of the cooking device of the present application is shown. It is shown that the lens 1111 is fixed on the light guide plate 1112, the light guide components 1113 are arranged on both sides of the light guide plate 1112, the light supplementing lamps 1114 are fixed on the light guide components 1113, and the light supplementing lamps 1114 on the light guide components 1113 supplement light for the lens 1111.

[0048] Exemplarily, in modern smart ovens and other cooking devices, real-time visual monitoring of the food cooking process has become a key function to improve user experience and control accuracy. However, due to the thickness of the cabinet door, high-temperature environment, and temperature resistance of electronic components, directly exposing the camera lens of the shooting assembly 113 to the high-temperature cavity for a long time has problems such as poor reliability, poor heat dissipation, and short service life. By setting a light guide structure 111 with a downwardly inclined mirror 1111 inside the cabinet door, the optical image of the food in the cooking cavity can be reflected by the mirror surface and guided to the camera located in the relatively low-temperature area of the cabinet door or away from the high-temperature area. This design effectively realizes light path transfer, so that the camera of the shooting assembly 113 does not need to face the high-temperature cavity directly, thereby avoiding direct heat shock of sensitive electronic components by high temperature, improving the stability and durability of the cooking device. At the same time, the obliquely arranged mirror can cover a wider field of view, ensuring that the food at different shelves or positions can be clearly imaged, especially suitable for multi-layer cooking scenes. The mirror can be made of optical materials with high-temperature resistance, high light transmittance, and anti-fog and anti-oil coating treatment to ensure good reflection performance and image clarity under complex working conditions.

[0049] The vertical movement assembly 112 arranged inside the cabinet door 11 is connected with the light guide structure 111 and used to drive the light guide structure 111 to move up and down;

[0050] Exemplarily, the camera or optical system in a conventional oven is usually fixedly installed, and its field of view is limited by the initial design angle, which can only cover a fixed height area in the cavity, resulting in difficulty for the user to comprehensively monitor the real-time state of the food at different layers during multi-layer cooking, especially when the food materials are at different heights or placed at different shelves. Some food materials may be in the blind area of the lens, and accurate image recognition and maturity judgment cannot be achieved. By introducing the vertical movement assembly 112 and rigidly connecting it with the light guide structure 111, the vertical reciprocating movement of the mirror 1111 can be realized, so as to dynamically adjust the incident angle and field of view of the optical reflection path. The vertical movement assembly 112 can include a motor 1121 and a guide rail 1122. When the light guide structure moves up and down, the downwardly inclined mirror can capture the images of the food at different heights in the cooking cavity in sequence, realizing layer-by-layer scanning and comprehensive coverage of the multi-layer food materials, and significantly improving the flexibility and integrity of imaging. This design not only avoids the operation burden of the user adjusting the position of the food materials to adapt to the lens, but also provides more rich and three-dimensional image data for the visual algorithm, which is helpful to accurately identify the key cooking features such as color change, swelling degree, and surface charring of the food materials, and to support intelligent functions such as automatic adjustment of cooking mode and prediction of completion time. In addition, the movement of the light guide structure can also drive the air flow inside the cabinet door, forming natural convection, assisting the heat dissipation of the camera and its surrounding circuit, relieving the heat accumulation problem in high-temperature and high-humidity environment, and improving the stability of long-term operation of the cooking device.

[0051] A shooting assembly arranged inside the cabinet door 11 is used to shoot images on the lens 111.

[0052] For example, in a multi-layer cooking scenario, food at different heights needs to be monitored synchronously to ensure uniform heating and ideal doneness. However, traditional fixed cameras can only cover a certain area and cannot meet this requirement. By using a vertically movable light guide structure and capturing images on the lens through the shooting assembly, comprehensive scanning of each layer of the cooking cavity can be achieved. When the vertical movement assembly drives the light guide structure to move vertically, the angle of the lens changes, and the images of food at different heights are reflected in turn. The shooting assembly records these dynamic image data in real time. In this way, food at both the upper and lower layers can be accurately included in the monitoring range, greatly improving the imaging flexibility and integrity.

[0053] In addition, the collection of reflected images on the lens by the shooting assembly can also provide high-quality data support for subsequent image processing and analysis. For example, advanced functions such as food color recognition, shape change monitoring, and doneness assessment can be achieved by combining image recognition algorithms, which helps to realize more intelligent cooking control strategies, such as automatic adjustment of temperature curve, prediction of optimal baking time, etc. At the same time, in order to further optimize the shooting effect, the shooting assembly inside the cabinet door can also be equipped with corresponding fill light to ensure that clear and bright images can be obtained under low light conditions. In addition, measures such as anti-fog coating and self-cleaning technology are taken to maintain long-term optical transparency in view of the problem of oil stains or fog on the surface of the lens.

[0054] A controller 12 is used to control the vertical movement assembly 112 to drive the light guide structure 111 to move up and down, acquire images shot by the shooting assembly 113, and send the images to a user terminal.

[0055] Illustratively, through the instructions issued by the controller 12 to the vertical motion assembly 112, the light guide structure 111 can be precisely lifted along the preset path, enabling the oblique lens 1111 to sequentially reflect the images of food at different heights in the cooking cavity, covering the full range of view of multiple layers of food. This dynamic scanning method avoids the problem of limited view of fixed cameras, ensuring that both upper roasted wings and lower vegetables can be clearly captured, providing comprehensive data support for subsequent image recognition and cooking state judgment. Secondly, the controller 12 receives and processes video streams or image frames from the shooting assembly 113 in real time, with image caching, compression and encoding capabilities, which can optimize data transmission efficiency while ensuring image quality. The controller 12 integrates a communication module, which can securely and stably transmit processed image data to user's mobile phone APP, tablet or small program terminal device through local network or cloud platform, realizing remote real-time viewing, video playback and intelligent reminding functions, enhancing the user's control of the cooking process and improving user experience.

[0056] In one embodiment, the light guide structure 111 further comprises a light guide plate 1112, and the lens 1111 is arranged on the light guide plate 1112; the edge of the light guide plate 1112 is provided with a wind guide part 1113 for guiding the airflow inside the cabinet door to flow.

[0057] Illustratively, the light guide plate 1112 as the main support component of the light guide structure not only provides a stable mounting base for the lens 1111, ensuring that it maintains accurate inclination angle and spatial position during up and down movement, avoiding imaging deviation caused by vibration or thermal deformation. Moreover, the structural design of the light guide plate 1112 facilitates rigid connection with the vertical motion assembly 112, enabling it to smoothly and reliably slide up and down with the motion assembly, thereby driving the lens to move synchronously and realize layer-by-layer scanning of different height regions in the cooking cavity, effectively covering the imaging needs of multiple layers of food.

[0058] During the operation of the steaming and baking oven, the internal space of the cabinet door is in a closed environment with high temperature and high humidity, especially the inner wall near the cooking cavity side, which can reach a temperature of 150℃ or above. The shooting assembly, circuit board and optical elements integrated in the cabinet door are long-term exposed to this environment, which is prone to performance degradation, increased image noise and even damage to components due to heat accumulation. The traditional passive heat dissipation method is limited by the thickness and sealing structure of the cabinet door, making it difficult to effectively dissipate heat. Therefore, by utilizing the mechanical kinetic energy of the up and down movement of the light guide plate 1112, the wind guide part 1113 is added to the edge, which can convert the original single optical component into a composite module with both light guiding and wind guiding functions.

[0059] In an embodiment, the light guide structure 111 further comprises a light supplement lamp 1114 arranged on the air guide component 1113 for supplementing light for the image on the lens 1111; and the controller 12 is configured to control the light supplement lamp 1114 to be turned on to supplement light for the image on the lens 1111.

[0060] For example, in actual operation, especially in the scenes of steam cooking, low-temperature fermentation or night use, the light in the cavity is dim, and it is difficult to meet the demand of high-definition imaging by relying on external transmitted light or weak thermal radiation generated by cavity heating, which may cause problems such as blurred image, low contrast and color distortion, and further affect the accurate judgment of food color, texture and maturity by image recognition algorithm. Therefore, the light supplement lamp 1114 is additionally arranged on the light guide structure to realize targeted and localized active illumination. Since the lens 1111 is used to reflect the image in the cooking cavity to the shooting assembly 113, the light supplement lamp is arranged on the air guide component 1113, which can be close to the optical path to ensure that the light is accurately projected to the field of view reflected by the lens, effectively illuminating the surface of the food and improving the brightness and clarity of the picture. The controller 12 as the core of the system not only controls the vertical movement assembly to move the light guide structure, but also intelligently controls the opening time, brightness level and working time of the light supplement lamp 1114 according to the preset program, feedback of the ambient light sensor or user instruction, to realize on-demand illumination, which not only guarantees the imaging quality, but also avoids unnecessary energy consumption and heating.

[0061] In an embodiment, the shooting assembly 113 comprises a camera 1131 vertically arranged at the bottom of the cabinet door 11 for shooting the image on the lens 1111; and a camera movement assembly 1132 arranged below the camera for driving the camera 1131 to move horizontally.

[0062] In the prior art, the inside of the cabinet door of the steam oven is in a harsh working environment with high temperature during operation, especially in the modes of steam heating and high-temperature baking, the temperature in the cavity can be maintained at above 100℃ for a long time, and the local temperature can even exceed 200℃. Some steam ovens arrange the camera above the exhaust port of the cabinet door, and the temperature is even higher. This poses a severe challenge to the camera and its surrounding electronic circuit installed in the cabinet door. The continuous high temperature not only accelerates the aging of electronic components, leading to performance degradation, color distortion or noise of the image sensor, but also may cause circuit board short circuit, soldering point falling off and other faults, which seriously affects the reliability and service life of the equipment. At the same time, in order to ensure the appearance and sealing performance of the whole machine, the structure design of the cabinet door of the steam oven is usually compact, and the overall thickness is limited, which greatly compresses the installation space of the camera and its supporting heat dissipation structure.

[0063] Reference Figure 3, shows the structural block diagram of another cooking device of the present application provided by the embodiment of the present application. The vertical movement component includes a driving motor 1122 and a vertical movement track 1121, and the light guide structure 111 can be fixed on the driving motor 1122 to move up and down on the vertical movement track 1121. The camera 1131 is vertically arranged at the bottom of the cabinet door 11 and adjacent to the air inlet 115 to reduce the temperature. The camera movement assembly 1132 is arranged below the camera to drive the camera 1131 to move horizontally. The cabinet door pull rod 114 is also arranged on the outer wall of the upper part of the cabinet door to facilitate the user to open the cabinet door.

[0064] Referring to Figure 4 , shows the temperature streamline diagram of a cooking device of the present application provided by the embodiment of the present application. Since the light guide structure 1111 is directed towards the cooking cavity, the up and down movement of the light guide structure 1111 can also make the temperature of the cabinet door outer wall adjacent to the cabinet door pull rod 114 lower, so as to avoid the user from being scalded by the cabinet door outer wall with high temperature when opening the cabinet door.

[0065] Illustratively, the camera 1131 is vertically installed at the bottom of the cabinet door adjacent to the air inlet at the bottom, so that the optical axis of the camera 1131 and the inclined lens 1111 in the light guide structure form a stable optical reflection path, ensuring that the image reflected by the lens in the cooking cavity can be accurately captured. This layout makes full use of the relatively spacious space at the bottom of the cabinet door away from the high temperature area, which is conducive to the heat dissipation and protection of the camera, while avoiding its direct exposure to the high temperature and high humidity environment, thereby improving the reliability of long-term operation of the equipment. By integrating the camera movement assembly 1132 (such as a micro stepping motor cooperating with a screw rod or a guide rail structure) below the camera, the camera 1131 can be driven to reciprocate in the horizontal direction, thereby changing the receiving angle of the camera relative to the lens. When the light guide structure 111 moves up and down to scan food materials at different heights, the horizontal displacement of the camera can realize multi-angle and multi-viewpoint image acquisition, effectively expand the field of view coverage, reduce the imaging blind area, and is especially suitable for complex scenes of simultaneous cooking of multi-layer or multi-plate food. In addition, the horizontal movement capability enables the system to realize image stitching, depth enhancement or even simple three-dimensional modeling through multi-frame synthesis or parallax calculation technology.

[0066] In an embodiment, the controller 12 is configured to acquire the position of the food in the cooking cavity, control the vertical movement assembly 112 to drive the light guide structure 111 to move to a height corresponding to the position of the food, control the camera movement assembly 1132 to drive the camera 1131 to move horizontally after the light guide structure 111 moves to the height corresponding to the position of the food, so that the camera 1131 captures images at different horizontal positions, splices the images at different horizontal positions, and sends the spliced images to a user terminal.

[0067] For example, the controller 12 first analyzes the vertical position of the food in the cooking cavity based on a series of images taken by the camera 1131 during the upward and downward movement of the light guide structure 111, through image recognition algorithms such as edge detection, feature matching or deep learning models. Since the light guide structure 111 can scan the entire cavity in the height direction under the drive of the vertical motion assembly 112, the controller 12 can obtain reflected images of different height regions frame by frame, and accurately determine the current position of the food by comparing the food outline, color change or heat distribution characteristics in the images. After determining the position of the food, the controller 12 further controls the vertical motion assembly 112 to accurately move the light guide structure 111 to the height corresponding to the position, so that the lens 1111 is directly opposite the food area, ensuring the best optical reflection angle and imaging clarity. Subsequently, after the light guide structure is positioned, the controller 112 starts the camera motion assembly 1132 to drive the camera 1131 to perform horizontal translation, thereby changing its receiving angle relative to the lens and realizing continuous shooting of the same height food at different lateral positions.

[0068] The controller 12 performs image stitching processing on multiple local images taken by the camera during horizontal movement, generates a complete and seamless panoramic image using feature point matching, perspective transformation and edge fusion algorithms, effectively eliminates the occlusion or distortion problem under a single viewing angle, and truly restores the overall state of the food. The controller 12 sends the high-definition image after stitching to the user's mobile phone APP, tablet or small program terminal device through the wireless communication module, so that the user can remotely and real-time view the cooking progress, improving the operation convenience and interactive experience. It breaks through the bottleneck of limited field of view of traditional fixed cameras, and can realize multi-angle and wide-face image acquisition of target food without increasing the size of the device.

[0069] In one embodiment, the shooting assembly 113 includes a bottom lens 1133 inclined upward toward the lens 1111 of the light guide structure 111 for reflecting the image on the lens 1111 of the light guide structure 111; a lens motion assembly 1134 arranged below the bottom lens 1133 for driving the bottom lens 1133 to move horizontally; and a camera 1131 horizontally arranged at the bottom of the cabinet door 11 for shooting the image on the bottom lens 1133.

[0070] Reference Figure 5, shows the structural block diagram of another cooking equipment of the present application provided by the embodiment of the present application. The camera 1131 can also be horizontally arranged at the bottom of the cabinet door 11 adjacent to the air inlet 115 to reduce the temperature. The bottom lens 1133 of the lens 1111 of the light guide structure 111 is arranged to reflect the image in the cooking cavity on the lens 1111 of the light guide structure 111 to the camera 1131. The lens movement assembly 1134 is arranged below the bottom lens 1133 to drive the horizontal movement of the bottom lens 1133.

[0071] The camera movement assembly 1132 is arranged below the camera to drive the horizontal movement of the camera 1131. The cabinet door pull rod 114 is arranged on the outer wall of the upper part of the cabinet door to facilitate the user to open the cabinet door.

[0072] For example, the bottom lens 1133 is inclined upward to the lens 1111 of the light guide structure 111 to receive and reflect the image of the lens 1111, so that the light path is turned, and the camera is horizontally installed at the bottom of the cabinet door instead of being vertically arranged. This optical relay design not only optimizes the use of internal space, but also keeps the camera away from the high temperature area, improves the working stability and service life of the camera. The camera 1131 is horizontally arranged and directly opposite the bottom lens 1133, which can directly shoot the food image reflected by the lens of the light guide structure. The lens movement assembly 1134 is arranged below the bottom lens to drive the horizontal movement of the bottom lens 1133, so as to change the reflection angle and the field of view. When the light guide structure 111 moves up and down to scan food materials at different heights, the horizontal displacement of the bottom lens can realize multi-angle image acquisition, expand the imaging coverage area, and avoid the blind area. By controlling the vertical movement of the light guide structure and the horizontal movement of the bottom lens through the controller, the system can realize dynamic tracking and panoramic shooting of the multi-layer and multi-position food in the cooking cavity. In addition, this design separates the moving parts and imaging parts, so that the camera body remains stationary, reduces the influence of vibration on the imaging quality, and facilitates the fixation, protection and heat dissipation of the camera.

[0073] In one embodiment, the controller 12 is configured to acquire the position of the food in the cooking cavity, control the vertical movement assembly 112 to drive the light guide structure 111 to move to the height corresponding to the position of the food, control the lens movement assembly 1134 to drive the bottom lens 1133 to move horizontally after the light guide structure 111 moves to the height corresponding to the position of the food, so that the camera 1131 shoots images at different horizontal positions, splices the images at different horizontal positions, and sends the spliced images to the user terminal.

[0074] For example, the controller 12 first uses the image sequence continuously captured by the camera 1131 during the movement of the light guide structure 111, combined with image recognition algorithms, to analyze the profile, color change and spatial distribution characteristics of the food at different height positions, and intelligently determine the specific shelf or vertical height position of the food in the cooking cavity. After completing the spatial positioning, the controller 12 sends instructions to the vertical motion assembly 112 to drive the light guide structure 111 to move accurately to the position corresponding to the height of the food, ensuring that the lens 1111 can reflect the image of the target area at the best angle, improving the imaging clarity and detail restoration capability. When the light guide structure 111 is positioned, the controller 12 further starts the lens motion assembly 1134 to drive the bottom lens 1133 to move uniformly or step by step in the horizontal direction. Since the bottom lens 1133 is obliquely aligned with the lens 1111 of the light guide structure, the horizontal displacement of the bottom lens 1133 changes the reflection path of the light path, so that the camera 1131 can continuously capture different local areas of the food at the same height from multiple lateral viewing angles.

[0075] The cooperative shooting of vertical positioning and horizontal scanning breaks through the limitation of narrow field of view of traditional fixed camera, and realizes wide-face and multi-angle image acquisition of the target food. Subsequently, the controller 12 performs image stitching processing on a series of local images obtained by the camera 1131 during the movement of the bottom lens, generates a complete and seamless panoramic image through feature point matching, perspective transformation and edge fusion algorithms, effectively eliminates the problems of occlusion, distortion or angle loss, and truly restores the overall state of the food. Finally, the controller 12 transmits the stitched high-definition image to the user terminal through the Wi-Fi or Internet of Things communication module, supports remote real-time viewing, video playback and intelligent analysis. The whole set of control logic not only realizes the technological leap from passive monitoring to active tracking, but also provides a high-quality data basis for automatic recognition of doneness, coking warning, intelligent power-off and other advanced functions, significantly improving the intelligent level, imaging accuracy and user experience of the equipment.

[0076] In one embodiment, the cabinet door 11 is provided with an air inlet 115 at the bottom for introducing cold air outside the cabinet door 11 into the cabinet door 11.

[0077] For example, the air inlet 115 is arranged at the bottom of the cabinet door, so that the shooting assembly 113 located at the bottom of the cabinet door is at a lower temperature, and the natural convection principle of hot air rising and cold air sinking can be used to guide the air outside the cabinet door to enter the space between the inner wall and the outer wall of the cabinet door from the bottom, forming an upward air flow channel. The cold air absorbs the heat emitted by the inner wall and the surrounding electronic elements during the flow process, effectively reducing the local temperature and improving the heat dissipation efficiency.

[0078] In an embodiment, the vertical movement assembly 112 includes a vertical movement track 1121 arranged at both ends of the cabinet door 11, and a driving motor 1122 arranged at both ends of the light guide structure 111, used to drive the light guide structure 111 to move up and down along the vertical movement track 1121.

[0079] Illustratively, the vertical movement track 1121 serves as a guiding and supporting structure, fixedly installed along the height direction of the cabinet door, providing a stable and low-friction sliding path for the lifting and lowering movement of the light guide structure, ensuring smooth and unbiased movement during reciprocating motion, avoiding optical reflection angle deviation caused by shaking, and affecting imaging quality. The driving motor 1122 is directly arranged at both ends of the light guide structure 111, cooperates with the movement track, and converts rotary power into linear motion through gear, belt or screw transmission mechanism, thereby directly driving the light guide structure to slide up and down along the track. Through the two-end driving mode, the stress distribution is more uniform, effectively avoiding the tilting or jamming problem caused by single-side driving, and improving the synchronization and reliability of movement. At the same time, the driving motor is integrated on the moving part, which can simplify the external transmission structure, reduce the space occupation, and adapt to the limited installation space inside the cabinet door. The driving motor can realize precise speed and position control under the instruction of the controller 12, support multi-grade lifting speed adjustment and precise positioning, and meet the imaging needs of different height food materials for layered scanning. In addition, this structure design is convenient for modular assembly and maintenance, and the cooperation of the track and the motor has good wear resistance and long-term running stability, which is suitable for frequent start-stop operation in high-temperature environment.

[0080] In an embodiment, the controller 12 is configured to determine the position of the food in the cooking cavity according to images of the light guide structure 111 at different positions captured by the camera 1131.

[0081] Illustratively, the light guide structure 111 moves up and down along the height direction of the cabinet door under the drive of the vertical movement assembly, and its lens 1111 constantly reflects the images of different height regions in the cooking cavity. These images are continuously captured by the camera 1131 and transmitted to the controller 12. The controller 12 has an image processing algorithm built-in, which can analyze these time-series images frame by frame, detect visual information such as food outline, color change, light and dark contrast or texture features, and determine the vertical height position of the food in the cavity, such as the upper, middle or lower grill. At the same time, the controller can also combine the projection range and edge definition of the food in the image to further improve the positioning accuracy and avoid misjudgment caused by obstruction or reflection.

[0082] The embodiment of the present application provides a cooking equipment, which comprises a cooking cavity, a cabinet door with an inner wall and an outer wall separated by a gap, a light guide structure arranged in the cabinet door and comprising a mirror which is inclined downward to the cooking cavity and used for reflecting an image in the cooking cavity, a vertical movement assembly arranged in the cabinet door and connected with the light guide structure and used for driving the light guide structure to move up and down, a shooting assembly arranged in the cabinet door and used for shooting the image on the mirror, and a controller used for controlling the vertical movement assembly to drive the light guide structure to move up and down, acquiring the image shot by the shooting assembly, and sending the image to a user terminal. The light guide structure which can move up and down is arranged in the cabinet door, and is driven by the vertical movement assembly, so that the shooting assembly can shoot food at different heights, and the imaging effect is improved. Meanwhile, the movement of the light guide structure can also enhance the heat dissipation of the shooting assembly.
