[0024] Example 1

[0025] Figure 1a A schematic diagram of the structure of an integrated stove is provided for Embodiment 1 of the present invention, as shown below. Figure 1aAs shown, the integrated stove includes a first image acquisition unit 101, a second image acquisition unit 102, a third image acquisition unit 103, a firepower adjustment module 104, a pot slip detection module 105, a tilt detection module 106, and an image processing module 107. The first image acquisition unit 101, the second image acquisition unit 102, and the third image acquisition unit 103 can be electrically connected to the image processing module 107. The pot slip detection module 105 and the tilt detection module 106 can be electrically connected to the image processing module 107 and the firepower adjustment module 104, respectively. It should be noted that the integrated stove includes an electric flame stove. The burner rack of the electric flame stove has at least two heating zones, enabling zoned heating. The firepower adjustment module 104 can asynchronously or synchronously control the at least two heating zones, performing asynchronous or synchronous heating.

[0026] The first image acquisition unit 101 can be located in the head area of ​​the integrated stove to acquire images of the cookware on the burner rack; the second image acquisition unit 102 can be located on the left side of the burner rack to acquire images of the cookware on the left side of the burner rack; the third image acquisition unit 103 can be located on the rear side of the burner rack to acquire images of the cookware on the rear side of the burner rack; the image processing module 107 can segment the images and identify the edges of the burner rack and the cookware in the images; the pot slip detection module 105 can be used to determine whether the cookware on the burner rack has slipped; the tilt detection module 106 can be used to determine whether the cookware on the burner rack has tilted. Optionally, the positions of the firepower adjustment module 104, the pot slip detection module 105, the tilt detection module 106, and the image processing module 107 can be adapted according to those skilled in the art, for example, they can be located in the head of the integrated stove.

[0027] Optionally, in the embodiments of the present invention, those skilled in the art can make adaptive settings for the type of integrated stove, without making specific limitations here. For example, the integrated stove can be set as an electric flame integrated stove, and the firepower of the electric flame stove can be controlled by controlling the power of the electric flame stove.

[0028] Figure 1b This is a flowchart illustrating a heat adjustment method provided in Embodiment 1 of the present invention. This embodiment is applicable to situations where the cookware slips or tilts during cooking. The method can be executed by a heat adjustment system, which can be implemented in hardware and / or software. This heat adjustment system can be configured in an integrated stove, such as an electric flame integrated stove. Figure 1b As shown, the method includes:

[0029] S110. The first image acquisition unit, the second image acquisition unit and the third image acquisition unit are used to acquire images of the integrated stove's rack, respectively, to obtain the first rack image, the second rack image and the third rack image.

[0030] The first stove frame image can be used to determine whether the cookware has slipped; the second stove frame image can be used to determine whether the cookware is tilted in the front-to-back direction; and the third stove frame image can be used to determine whether the cookware is tilted in the left-to-right direction. It should be noted that the first, second, and third stove frame images can all refer to images of the cookware on the stove frame.

[0031] In this embodiment of the invention, when the integrated stove is in operation, the first image acquisition unit, the second image acquisition unit, and the third image acquisition unit disposed in the head area of ​​the integrated stove can respectively acquire images of the stove frame area at a preset acquisition frequency, thereby obtaining the first stove frame image, the second stove frame image, and the third stove frame image. Optionally, the preset acquisition frequency can be adaptively set according to those skilled in the art.

[0032] Optionally, the activation of the first, second, and third image acquisition units can be controlled according to the working status of the integrated stove. When the integrated stove is in operation, the first, second, and third image acquisition units can be automatically activated. Alternatively, temperature sensors can be installed in the first, second, and third image acquisition units to monitor the temperature of the stove rack area. When the temperature detected by any temperature sensor exceeds a certain threshold, the first, second, and third image acquisition units will be activated to acquire images. When the integrated stove is not in operation, the image acquisition units can be in a sleep state.

[0033] S120. The sliding pot detection module is used to detect the sliding pot based on the image of the first furnace frame and determine the direction of the sliding pot.

[0034] The direction of the pan's movement can be used to characterize the direction in which the cookware slides on the stove rack.

[0035] In this embodiment of the invention, during cooking on the stove rack, the cookware may slip, meaning its position on the stove rack shifts, causing uneven heating and resulting in dry burning or spillage of the cooked food. A slip detection module can detect this slippage based on a first image of the stove rack acquired by a first image acquisition unit, identifying the position of the cookware and the stove rack in the image to determine whether the cookware has slipped and, consequently, the direction of the slippage.

[0036] S130. The tilt detection module is used to detect the tilt of the cookware based on the second and third stove frame images to determine the tilt direction of the cookware.

[0037] In this embodiment of the invention, during cooking on the stove rack, the cookware may tilt, meaning the bottom of the cookware may not be fully in contact with the stove rack, and the cookware may not be in a horizontal position. This can cause uneven heating, resulting in the cookware drying out or spilling of the food. A tilt detection module can detect the tilt of the cookware based on the second and third stove rack images acquired by the second and third image acquisition units. This module identifies the edge position of the cookware in the second and third stove rack images to determine whether the cookware is tilted and, consequently, the direction of tilt.

[0038] S140: The firepower adjustment module adjusts the cooking firepower of the integrated stove based on the direction of the sliding pot and the tilt direction.

[0039] Specifically, when it is determined that the cookware is slipping or tilting, a heat adjustment module can be used to adjust the heat of the integrated stove's burner area based on the direction of slippage or tilt. It should be noted that the burner (the internal space of the burner) in the integrated stove's burner rack has at least two heating zones, and the heat adjustment module can asynchronously or synchronously control these at least two heating zones. It should also be noted that the cookware may only slip, or only tilt, or both may occur simultaneously on the burner rack. In this embodiment of the invention, the cooking heat of the integrated stove can be adjusted based on the direction of slippage and / or tilt of the cookware on the burner rack.

[0040] Optionally, the firepower adjustment module adjusts the cooking firepower of the integrated stove based on the pan sliding direction and the tilt direction, including: using the firepower adjustment module to increase the firepower of the stove heating area corresponding to the pan sliding direction by a first preset adjustment ratio, and to decrease the firepower of the stove heating area corresponding to the opposite direction of the pan sliding direction by a first preset adjustment ratio; using the firepower adjustment module to increase the firepower of the stove heating area corresponding to the tilt direction by a second preset adjustment ratio, and to decrease the firepower of the stove heating area corresponding to the opposite direction of the tilt direction by a second preset adjustment ratio.

[0041] The first preset adjustment ratio can be determined based on the sliding distance of the pot in the sliding direction; the second preset adjustment ratio can be determined based on the tilt angle. It should be noted that the greater the sliding distance, the larger the first preset adjustment ratio, and the greater the tilt angle, the larger the second preset adjustment ratio.

[0042] For example, if the pot slides to the right, that is, if the pot slides to the right on the stove rack, the heating area of ​​the pot on the right side of the stove increases compared to its position before the sliding, while the heating area on the left side of the stove decreases. If the stove's heating area continues to heat the pot at the same heat level as before the sliding, the bottom right side of the pot is very likely to burn. The heating power of the right side of the stove can be increased by adjusting the heat level, thereby increasing the heat level of the right side heating area, while the heating power of the left side of the stove can be decreased to reduce the heat level of the left side heating area. If the cookware tilts to the right or forward, compared to its initial tilt position, the cooking heat of the heating areas on the right and front sides of the stove needs to be increased, while the heat of the heating areas on the left and rear sides needs to be decreased. If the heating areas in the stove maintain the same heat level as before the tilt, the bottom left and front sides of the cookware are prone to burning. The heat adjustment module can be used to increase the heating power of the right and front sides to enhance their heat, while simultaneously decreasing the heating power of the left and rear sides. It should be noted that there must be at least one heating area corresponding to the direction the cookware tilts, and at least one heating area corresponding to the direction the cookware tilts.

[0043] By dynamically adjusting the heat of different heating zones in the stove, the cooking process can be ensured to proceed smoothly and safety can be improved.

[0044] Optionally, the firepower adjustment module adjusts the cooking firepower of the integrated stove based on the sliding pot direction and tilt direction. It also includes: if the sliding distance of the pot on the stove rack in the sliding pot direction is greater than a preset distance threshold, the firepower adjustment module will turn off the firepower of the stove heating area corresponding to the opposite direction of the sliding pot direction.

[0045] For example, if the sliding distance of the pot on the burner rack of the integrated stove to the right exceeds a preset distance threshold, it indicates that the pot, after sliding, is positioned on the burner rack where the heating area on the left side of the stove is essentially unable to heat it. In other words, the pot, after sliding, is positioned on the burner rack too far from the heating area on the left side of the stove. To prevent the heating area on the left side from continuing ineffective heating and to avoid dry burning, the heating power of the heating area on the left side of the stove can be turned off via the power adjustment module, thus shutting down the heat output of the left-side heating area. Optionally, the preset distance threshold can be adaptively set according to those skilled in the art.

[0046] Optionally, the firepower adjustment module adjusts the cooking firepower of the integrated stove based on the direction of the sliding pot and the tilt direction. It also includes: if the tilt angle of the pot on the stove rack in the tilt direction is greater than a preset angle threshold, the firepower adjustment module will turn off the firepower of all stove heating areas of the integrated stove.

[0047] For example, if the tilt angle of the pot on the integrated stove's burner rack is greater than a preset angle threshold, indicating that the pot is about to tip over, the heating power input to all heating zones of the stove can be cut off via the firepower adjustment module to shut off the cooking firepower of the integrated stove and prevent dry burning. Optionally, the preset angle threshold can be adaptively set according to those skilled in the art.

[0048] The technical solution of this invention acquires images of the stove rack area and determines the direction of pan slippage and tilt based on the acquired images. The heat of the integrated stove's stove rack area is then adjusted according to the pan slippage and tilt directions. This prevents pan slippage or tilting that could cause burning or drying out of the pan, improving cooking safety and enhancing the intelligence of the integrated stove. Furthermore, it ensures the safety of the cooking process even when unattended.

[0049] Example 2

[0050] Figure 2a This is a flowchart of a firepower adjustment method provided in Embodiment 2 of the present invention. This embodiment, based on the above embodiments, provides specific steps for the image processing module to process images. It should be noted that for parts not described in detail in this embodiment, please refer to the relevant descriptions in other embodiments, which will not be repeated here. Figure 2a As shown, the method includes

[0051] S210. The image processing module is used to divide the first furnace frame image into regions, and the first furnace frame region image is divided into at least two image segmentation regions, and the gap area between the pot and the edge of the furnace frame in each image segmentation region is determined.

[0052] S220. The image processing module takes the first image of the first stove frame acquired by the first image acquisition unit and uses the gap area between the pot and the edge of the stove frame in each image segmentation region of the first stove frame image as the initial area corresponding to the image segmentation region.

[0053] S230. Using an image processing module with the horizontal placement surface of the stove frame as the standard baseline, image processing is performed on the second and third stove frame images to determine the tilt angle of the cookware in the front-back and left-right directions.

[0054] The gap area can be used to characterize the distance between the cookware and the edge of the stove rack; the first image of the stove rack acquired initially can refer to the first image acquired by the first image acquisition unit after startup. It should be noted that the horizontal placement surface of the stove rack can refer to the landing surface of the cookware on the stove rack. Since the stove rack is fixed to the integrated stove, it is not easy for the stove rack to shift or tilt. Using the horizontal placement surface of the stove rack as a baseline can effectively detect whether the cookware is tilted.

[0055] Optionally, the image processing module can divide the first furnace frame image into at least two image segmentation regions, using the center point of the furnace frame in the first furnace frame image as a reference, such as... Figure 2b As shown, the first furnace frame image is divided into four image segmentation regions: a first sector region, a second sector region, a third sector region, and a fourth sector region. Figure 2b The black circular area shown represents the region formed by the edge of the cookware and the edge of the stove rack, i.e., the area within the stove rack not occupied by the cookware. Each sector contains a portion of the black circular area, used to indicate the distance between the edge of the cookware and the edge of the stove rack within each sector. Optionally, in this embodiment of the invention, the first, second, third, and fourth sector areas can respectively correspond to the four heating areas of the stove.

[0056] Optionally, image processing is performed on the second and third stove frame images, including: using the horizontal line indicated by the horizontal placement surface of the stove frame as a standard reference line, performing horizontal detection on the edge of the cookware indicated in the second and third stove frame images; when the standard reference line intersects with the edge of the cookware indicated in the second or third stove frame image, taking the first or second angle formed by the standard reference line and the edge of the cookware as the tilt angle of the cookware.

[0057] The first included angle can be used to indicate the tilt angle of the cookware in the front-to-back direction; the second included angle can be used to indicate the tilt angle of the cookware in the left-to-right direction.

[0058] Optionally, in another optional embodiment of the present invention, a pot slip detection module is used to detect pot slippage based on the first stove frame image and determine the pot slippage direction. This includes: using the pot slip detection module, comparing the gap area between the pot and the edge of the stove frame corresponding to each of the at least two image segmentation regions divided by the first stove frame image with the initial area corresponding to each image segmentation region. If the gap area corresponding to the image segmentation region is reduced by a preset area compared with its corresponding initial area, then the direction of the image segmentation region is determined to be the pot slippage direction.

[0059] Specifically, if, before and after the cookware slides, the gap area corresponding to a certain image segmentation region decreases by a preset area compared to its initial area, then it is determined that the cookware has slid towards that image segmentation region, and the direction of that image segmentation region is the direction of movement of the cookware. It should be noted that, in this embodiment of the invention, the sliding distance of the cookware in each image segmentation region can be determined by the difference in gap area before and after the cookware slides. The larger the difference in gap area, the greater the sliding distance of the cookware in the current image segmentation region. Furthermore, the cookware can slide towards at least one image segmentation region simultaneously; that is, the direction in which the cookware slides during cooking is random and not limited to just one direction.

[0060] Optionally, in another optional embodiment of the present invention, a tilt detection module is used to perform cookware tilt detection based on the second and third stove frame images, including: using the tilt detection module to compare the tilt angles of the cookware in the front-back direction and the left-right direction indicated by the second and third stove frame images with a preset tilt angle threshold; if the tilt angle of the cookware is greater than the tilt angle threshold, then the side of the cookware edge that is lower than the standard baseline is taken as the tilt direction of the cookware.

[0061] It should be noted that if the cookware tilts forward at a 15° angle, the rear of the cookware will also tilt simultaneously at a 15° angle. The difference is that when the cookware tilts forward, the front bottom of the cookware will not leave the stove rack, while the rear bottom of the cookware will lift off the stove rack and tilt upwards. Therefore, the direction in which the cookware tilts is the side of the cookware whose edge is lower than the baseline.

[0062] Specifically, the angle at which the cookware tilts in all directions can be compared with a pre-set tilt angle threshold. If the tilt angle of the cookware is greater than the tilt angle threshold, it indicates that the cookware is tilted. In this case, the side of the cookware edge that is lower than the baseline can be taken as the tilt direction of the cookware. Optionally, the tilt angle threshold can be used to characterize the minimum tilt angle that affects the cooking process, and the tilt angle threshold can be adaptively set by those skilled in the art.

[0063] Optionally, in this embodiment of the invention, an image processing module can be used to generate a tilt array based on the tilt angle of the cookware. The tilt array is used to characterize the tilt angle of the cookware in the front-back direction and the left-right direction. For example, an array can be defined to represent the offset angle in the direction of "direction: offset angle". This array can store the offset angle in at least one direction. Then, the image processing module can send this array to the tilt detection module to determine the tilt direction of the cookware, reducing the amount of data transmission and improving the efficiency of tilt direction determination.

[0064] Optionally, in one specific embodiment, the integrated stove's cooktop can be equipped with four heating zones within the cooktop frame. These zones can be divided into four equal-sized heating zones using the center point of the cooktop as a reference and the straight line between the second and third image acquisition units. Figure 2b The diagram shows the first, second, third, and fourth sector-shaped areas. If the cookware tilts forward, the cooking heat in the third and second sector-shaped areas can be increased accordingly, while the cooking heat in the first and fourth sector-shaped areas can be decreased. Optionally, the second image acquisition unit can be positioned to the left of the center point of the burner rack in the integrated stove, and the third image acquisition unit can be positioned behind the center point of the burner rack in the integrated stove.

[0065] The technical solution of this invention divides the image of the stove rack area and characterizes the position information of the pot based on the gap area between the pot and the edge of the stove rack in each segmented image area. It also identifies the edge position information of the pot and the horizontal placement surface information of the stove rack. Furthermore, it determines the sliding direction of the pot based on the gap area between the pot and the edge of the stove rack in each segmented image area and performs horizontal detection based on the edge position information and the horizontal placement surface information of the pot. This can automatically identify the relative positional relationship between the pot and the stove rack, improve the efficiency of pot slip detection and tilt detection, and enhance the intelligence level of the integrated stove.

[0066] Example 3

[0067] Figure 3 This is a schematic diagram of a fire control system provided in Embodiment 3 of the present invention. This fire control system can be configured in an integrated stove. Figure 3 As shown, the system includes a first image acquisition unit, a second image acquisition unit, a third image acquisition unit, a firepower adjustment module, a pot sliding detection module, and a tilt detection module.

[0068] The first image acquisition unit, the second image acquisition unit, and the third image acquisition unit are respectively used to acquire images of the integrated stove's burner frame, obtaining a first burner frame image, a second burner frame image, and a third burner frame image; wherein, the second burner frame image is used to determine whether the cookware is tilted in the front-back direction; and the third burner frame image is used to determine whether the cookware is tilted in the left-right direction.

[0069] The pot sliding detection module is used to detect pot sliding based on the first stove frame image and determine the pot sliding direction; wherein, the pot sliding direction is used to characterize the sliding direction of the pot on the stove frame;

[0070] The tilt detection module is used to detect the tilt of the cookware based on the second stove frame image and the third stove frame image, and to determine the tilt direction of the cookware.

[0071] The firepower adjustment module is used to adjust the cooking firepower of the integrated stove based on the direction of the sliding pot and the tilting direction.

[0072] The technical solution of this invention acquires images of the stove rack area and determines the direction of pan slippage and tilt based on the acquired images. The heat of the integrated stove's stove rack area is then adjusted according to the pan slippage and tilt directions. This prevents pan slippage or tilting that could cause burning or drying out of the pan, improving cooking safety and enhancing the intelligence of the integrated stove. Furthermore, it ensures the safety of the cooking process even when unattended.

[0073] Optionally, the system further includes an image processing module, which includes:

[0074] The gap area determination unit is used to divide the first stove frame image into regions, divide the first stove frame region image into at least two image segmentation regions, and determine the gap area between the pot and the edge of the stove frame in each image segmentation region.

[0075] The initial area determination unit is used to determine the initial area of ​​the first stove frame image initially acquired by the first image acquisition unit, and to use the gap area between the pot and the edge of the stove frame in each image segmentation region of the first stove frame image as the initial area corresponding to the image segmentation region; the gap area is used to characterize the distance between the pot and the edge of the stove frame.

[0076] The tilt angle determination unit is used to perform image processing on the second and third stove frame images with the horizontal placement surface of the stove frame as the standard reference line, and to determine the tilt angle of the cookware in the front-back direction and the left-right direction.

[0077] Optionally, the tilt angle determination unit may be specifically used to: use the horizontal line indicated by the horizontal placement surface of the stove rack as a standard reference line, perform horizontal detection on the edge of the cookware indicated in the second stove rack image and the third stove rack image, and when the standard reference line intersects with the edge of the cookware indicated in the second stove rack image or the third stove rack image, take the first angle or the second angle formed by the standard reference line and the edge of the cookware as the tilt angle of the cookware; wherein, the first angle is used to indicate the tilt angle of the cookware in the front-back direction; and the second angle is used to indicate the tilt angle of the cookware in the left-right direction.

[0078] Optionally, the pan slip detection module can be specifically used to: compare the gap area between the pan and the edge of the stove frame corresponding to each of the at least two image segmentation regions divided by the first stove frame image with the initial area corresponding to each image segmentation region. If the gap area corresponding to the image segmentation region is reduced by a preset area compared with its corresponding initial area, then the direction of the image segmentation region is determined to be the pan slip direction.

[0079] Optionally, the tilt detection module can be specifically used to: compare the tilt angles of the cookware in the front-back direction and the left-right direction indicated by the second and third stove frame images with a preset tilt angle threshold.
