[0088] With the advancement of technology and the accelerated promotion of smart kitchen in family, as the core tool of cooking, the stove not only greatly improves the convenience of cooking, but also promotes the overall optimization of the kitchen environment.

[0089] In the cooking process, the stove provides a stable and controllable heat source, which can ensure that the food is heated sufficiently and retains its best flavor, whether it is dealing with food such as noodles and dumplings that are prone to overflow, or processing various dishes that are fried, cooked, and fried.

[0090] However, in the existing stove fire adjustment scheme, the user must be present throughout the process, manually monitoring and frequently adjusting the stove fire to cope with the changing stages and complex food requirements in the cooking process. But the manual adjustment method often fails to cope with complex and variable cooking scenarios, which may affect the cooking results due to judgment errors or reaction delays, and may even cause safety hazards such as pot overheating, dry burning, etc. due to improper fire control, resulting in damage to the pot and even the stove.

[0091] To solve the above problems, the present application provides a stove control method. Figure 2 The scene diagram of the stove control method provided by the present application is shown in FIG. Figure 2 As shown, the cloud platform 3 is in communication connection with the range hood 1 and the stove 2, and the range hood 1 and the stove 2 can be connected by Bluetooth or communication connection. When the range hood 1 determines that the stove 2 is in the fire-on state, it will capture the real-time image above the stove 2 to identify whether there is a pot 3 and whether there is cooking material in the pot 3. After confirming that there is a pot 3 above the stove 2 and there is no cooking material in the pot 3, the range hood 1 will further determine whether the temperature of the pot 3 is greater than or equal to the first temperature threshold. If it is determined that the temperature of the pot 3 is greater than or equal to the threshold, the range hood 1 will send a fire-off instruction to the stove 2, and the stove 2 will respond immediately and execute the fire-off operation after receiving the instruction.

[0092] The method first captures a first image on the stove when the stove is in the fire-on state, and then determines a first recognition result corresponding to the first image based on the first image, which includes whether a pot is placed on the stove and whether the pot contains cooking material. Next, based on the first recognition result, the range hood or the cloud platform will intelligently adjust the fire of the stove. Then, after receiving the fire instruction sent by the range hood or the cloud platform, the stove will immediately execute the fire instruction. This method solves the problem that manual adjustment is difficult to cope with complex and variable cooking scenarios, thereby avoiding the decline in cooking results due to judgment errors or reaction delays, and the risk of damage to the pot and the stove caused by improper fire, thereby enhancing the safety of the cooking process.

[0093] The technical solutions of the present application and how the technical solutions of the present application solve the above technical problems will be described in detail below with specific examples. The following specific examples can be combined with each other, and the same or similar concepts or processes can not be described again in some examples. The embodiments of the present application will be described below with reference to the drawings.

[0094] Figure 3 Flowchart of the stove control method provided by the embodiments of the present application Figure 1 . As shown in Figure 3 , the stove control method provided by the embodiments of the present application comprises:

[0095] S301: sending the working state of the stove to the range hood or the cloud platform.

[0096] The working state includes but is not limited to: the fire-on state and the fire-off state. The fire-on state means that the ignition device of the stove has been activated, and the flame has been burning steadily on the burner of the stove. The fire-off state means that the ignition device of the stove has not been activated, and there is no flame burning on the burner of the stove.

[0097] The purpose of this step is to inform the range hood or the cloud platform of the working state of the stove at the current time.

[0098] It can be understood that the range hood is used to absorb and remove the oil fume and steam generated during the cooking process, and its working principle does not include directly detecting the ignition state or flame burning condition of the stove. The cloud platform is a remote information processing system, which relies on input data from various devices (such as stoves, range hoods, etc.) to perform analysis and control operations, and it itself does not have the ability to directly perceive specific events in the physical environment.

[0099] Therefore, in order to ensure that the range hood or the cloud platform can obtain the real-time working state of the stove, the stove needs to actively send its working state information to the range hood or the cloud platform.

[0100] Optionally, in the scenario where the range hood is the execution subject, when the working state of the stove is reported to the cloud platform, and the working state of the stove is not reported to the range hood, the present application provides a way for the range hood to determine the working state of the stove, which specifically comprises: the range hood obtains the working state of the stove from the cloud platform.

[0101] Optionally, in the scenario where the cloud platform is the execution subject, when the working state of the stove is reported to the cloud platform, the present application provides a way for the cloud platform to determine the working state of the stove, which specifically comprises: receiving the working state of the stove sent by the stove.

[0102] It can be understood that, in the process of interaction between the cloud platform and the stove, the stove actively sends its current working state information to the cloud platform, so that the cloud platform can master the working details of the stove in real time. Once the cloud platform receives this information, it can quickly and effectively process or adjust based on the real-time working state of the stove to ensure the safety of the cooking process.

[0103] S302: In the case that the stove is in the state of having been ignited, a first image obtained by photographing the stove is acquired.

[0104] It can be understood that, in the process of interaction between the cloud platform and the stove, the stove actively sends its current working state information to the cloud platform, so that the cloud platform can master the working details of the stove in real time. Once the cloud platform receives this information, it can quickly and effectively process or adjust based on the real-time working state of the stove to ensure the safety of the cooking process.

[0105] It can be understood that, in the case that the smoke machine or the cloud platform determines that the stove is in the state of having been ignited, in order to ensure the safety of the cooking process, the smoke machine or the cloud platform will photograph the stove and its surrounding environment, thereby obtaining the real-time image of the stove, i.e. the first image.

[0106] In this step, different execution subjects acquire the first image of the stove in different ways. For example, in the case that the execution subject is the smoke machine, the first image can be obtained by the smoke machine photographing by using its built-in camera, and in the case that the execution subject is the cloud platform, the first image can be obtained by the cloud platform controlling the smoke machine to photograph by using its built-in camera and receiving the image returned by the smoke machine, or by the cloud platform controlling other cameras to photograph and receiving the image returned by the other cameras. The present application does not make special limitations on this.

[0107] S303: Determine a first recognition result of image recognition on the first image, the first recognition result including whether there is a pot on the stove in the first image, and in the case that there is a pot on the stove in the first image, whether there is a cooking object in the pot.

[0108] It can be understood that, in the process of interaction between the cloud platform and the stove, the stove actively sends its current working state information to the cloud platform, so that the cloud platform can master the working details of the stove in real time. Once the cloud platform receives this information, it can quickly and effectively process or adjust based on the real-time working state of the stove to ensure the safety of the cooking process.

[0109] It can be understood that, as the initial screen representation of the stove and its surrounding environment, the first image contains but is not limited to information such as the stove, the pot and the cooking object. This image can accurately reflect the state of the stove and its current working environment. Therefore, by recognizing the acquired image, the recognition result corresponding to the image can be obtained, i.e. whether there is a pot on the stove and whether there is a cooking object in the pot if the pot exists.

[0110] S304: Adjust the firepower of the stove based on the first recognition result.

[0111] The purpose of this step is to ensure that the stove can automatically and accurately adjust the firepower according to the real-time cooking state and needs during the cooking process.

[0112] It can be understood that the first identification result provides real-time state information of the stove and its surrounding environment, including whether there is a pot on the stove and whether the pot contains cooking materials. These information constitutes the direct basis for adjusting the firepower of the stove. Therefore, the smoke machine and the cloud platform can use these identification results to analyze and judge the current cooking state of the stove in real time, and then automatically adjust the firepower according to the cooking needs, so as to ensure that the stove, the pot and the food materials in the cooking process are in a safe and suitable state.

[0113] S305: In the case that the working state of the stove is the fire-on state, receiving the firepower adjustment instruction sent by the smoke machine or the cloud platform, the firepower adjustment instruction is determined based on the existence of the pot on the stove in the first image obtained by taking a picture of the stove, and whether there is cooking material in the pot under the condition that the first image exists on the stove.

[0114] The purpose of this step is to ensure that the stove can respond immediately and adapt to the current cooking needs and environmental changes.

[0115] It can be understood that the firepower adjustment instruction is based on the analysis of the first image, which accurately reflects the state of the pot and the cooking material on the stove, and the optimal firepower adjustment strategy is formulated by the smoke machine or the cloud platform. Therefore, by receiving the firepower adjustment instruction sent by the smoke machine or the cloud platform, the stove can automatically and quickly adjust to the most appropriate firepower level, thereby maintaining the continuity and stability of the cooking process.

[0116] S306: Adjusting the firepower of the stove based on the firepower adjustment instruction.

[0117] The purpose of this step is to ensure that the stove can respond immediately and adapt to the current cooking needs and environmental changes.

[0118] It can be understood that the firepower adjustment instruction is based on the analysis of the real-time image of the stove and its surrounding environment, which reflects the state of the pot and the cooking material on the stove, and the optimal firepower adjustment scheme is formulated accordingly. Therefore, by taking the firepower adjustment instruction as a determining factor to adjust the firepower of the stove, the stove can respond immediately to any changes in the cooking process and automatically adjust to the most appropriate firepower level, thereby not only ensuring the continuity and stability of the cooking process, but also indirectly improving the safety of the cooking process, avoiding potential safety hazards caused by improper firepower.

[0119] The stove control method provided by the embodiment, when the stove is working, will first send its current working state to the range hood or cloud platform in real time. Once the stove enters the fire-on state, the range hood or cloud platform will immediately automatically capture the real-time image of the stove, and apply image recognition technology for analysis to obtain the first recognition result. This result not only judges whether there is a pot placed on the stove, but also further identifies whether the pot contains cooking materials. Based on these accurate identification information, the range hood or cloud platform can intelligently generate and send a firepower adjustment instruction to the stove. After receiving the instruction, the stove will quickly respond and automatically adjust the firepower size to adapt to the current cooking demand and pot state.

[0120] This method changes the cumbersome process of manual monitoring and frequent adjustment of firepower in the existing cooking process, effectively solving the problem that manual adjustment is difficult to cope with complex and variable cooking scenes. It avoids the decline of cooking effect caused by judgment error or reaction lag, and the risk of damage to the pot and stove caused by improper firepower, thereby greatly improving the convenience, safety and efficiency of cooking.

[0121] Figure 4 The flowchart of the stove control method provided by the embodiment Figure 2 . As Figure 4 shown, the embodiment Figure 3 on the basis of the embodiment, the stove control method is described in detail, the stove control method shown in the embodiment includes:

[0122] S401: In the state that the stove is in the fire-on state, a first image obtained by taking a picture of the stove is acquired.

[0123] Optionally, in the working scenario where the execution subject is the cloud platform, the application provides a way for the cloud platform to acquire the first image of the stove, which specifically includes: controlling the range hood to take a picture of the stove, and receiving the first image sent by the range hood.

[0124] Wherein, the purpose of this step is to obtain the image information of the stove at the current time.

[0125] It can be understood that since the cloud platform cannot directly observe or capture the image of the stove, the cloud platform can take a picture of the stove with the camera device on the range hood, and receive the first image sent by the range hood. In this way, the cloud platform can obtain the image information of the stove at the current time.

[0126] S402: Determine the first recognition result of image recognition on the first image, and the first recognition result includes whether there is a pot on the stove in the first image, and whether there is cooking material in the pot when there is a pot on the stove in the first image.

[0127] The explanation of step S402 can refer to the above-mentioned explanation of the embodiments, which will not be repeated here.

[0128] S403: determining whether there is a pot on the cooktop in the first image; if yes, performing step S404; if no, performing step S408.

[0129] The purpose of determining whether there is a pot on the cooktop in the first image is to determine whether the cooktop is in a dry burning state.

[0130] It can be understood that the dry burning state means that the user forgets to place the pot during the cooking process, or the user removes the pot on the cooktop. Therefore, by taking the first image as a judgment factor to determine whether there is a pot on the cooktop, it can be determined whether the pot is in a dry burning state.

[0131] If there is a pot on the cooktop in the first image, it indicates that the cooktop is not in a dry burning state, at this time, it can be determined whether there is a cooking object in the pot.

[0132] If there is no pot on the cooktop in the first image, it indicates that the cooktop is in a dry burning state, at this time, the first minimum fire instruction can be sent to the cooktop.

[0133] Optionally, in the scenario where the execution subject is a hood, the present application provides a way for the hood to process the first image of the cooktop, which specifically includes: the hood sends the first image to the cloud platform and receives the first identification result sent by the cloud platform.

[0134] The purpose of sending the first image to the cloud platform is to use the image recognition technology of the cloud platform to quickly analyze the first image. And the purpose of receiving the first identification result sent by the cloud platform is to obtain the identification result of the first image by the cloud platform.

[0135] It can be understood that the cloud platform can process complex image data and identify whether there is a pot on the cooktop and whether there is a cooking object in the pot and other key information in the image. Therefore, by sending the first image to the cloud platform and receiving the identification result feedback by the cloud platform, not only the work burden of the hood can be reduced, but also the accuracy and efficiency of image recognition can be improved.

[0136] S404: determining whether there is a cooking object in the pot; if yes, performing step S413; if no, performing step S405.

[0137] The purpose of determining whether there is a cooking object in the pot is to determine whether the pot on the cooktop is in an empty burning state during the cooking process.

[0138] It can be understood that the empty burning state means that the user forgets to place the food to be cooked in the pot during the cooking process. Therefore, by taking the pot as a judgment factor to determine whether there is food to be cooked in the pot, it can be determined whether the pot on the stove is in an empty burning state.

[0139] If there is cooking material in the pot, it indicates that the pot on the stove is not in an empty burning state, that is, the stove is not in a dry burning state, at which time the third image obtained by photographing the stove can be acquired.

[0140] If there is no cooking material in the pot, it indicates that the pot on the stove is in an empty burning state during the cooking process, that is, the stove is not in a dry burning state, at which time the temperature of the pot can be acquired.

[0141] S405: Acquire the temperature of the pot.

[0142] The temperature of the pot refers to the actual temperature reached by the pot during heating by the stove. The temperature of the pot may be, for example, 150 degrees or 200 degrees.

[0143] In the case where it is determined from the first image that there is a pot on the stove and there is no cooking material in the pot, it indicates that the pot on the stove has an empty burning phenomenon. Therefore, in order to avoid safety hazards of the stove in the case of empty burning of the pot, the temperature of the pot needs to be acquired.

[0144] It can be understood that the empty burning phenomenon indicates that the user may forget to place the food material in the pot during the cooking process. Empty burning can cause the temperature of the pot to rise rapidly, which may cause safety hazards such as damage to the pot, fire, etc. Therefore, in order to avoid this situation, the current temperature information of the pot needs to be acquired in time.

[0145] In this step, different execution subjects acquire the temperature of the pot in different ways. For example, in the case where the execution subject is a hood, the temperature of the pot may be acquired by the hood using its built-in infrared temperature sensor, and in the case where the execution subject is a cloud platform, the temperature of the pot may be acquired by the cloud platform controlling the hood to detect using its built-in infrared temperature sensor and receiving the temperature returned by the hood. The present application does not make special limitations in this regard.

[0146] S406: Determine whether the temperature of the pot is greater than or equal to a first temperature threshold; if yes, execute step S407; if no, execute step S405.

[0147] The first temperature threshold may be, for example, 300 degrees. The present application does not make special limitations in this regard.

[0148] The purpose of determining whether the temperature of the pot is greater than or equal to the first temperature threshold is to determine whether the temperature of the pot is too high in the case of empty burning.

[0149] If the temperature of the pot is greater than or equal to the first temperature threshold, it indicates that the temperature of the pot is too high in the case of empty burning, at which time the smoke machine or the cloud platform will send a fire-off instruction to the stove.

[0150] It can be understood that, in the cooking process of the stove, in order to prevent the temperature of the pot from being too high due to empty burning, the smoke machine or the cloud platform will monitor the temperature of the pot in real time. When the temperature of the pot reaches or exceeds the preset first temperature threshold, in order to avoid potential safety risks, the smoke machine or the cloud platform will automatically send a first fire-off instruction to the stove, instructing the stove to immediately turn off the fire, thereby protecting the pot and the stove from being damaged.

[0151] Optionally, the application also provides a method, which first detects whether the temperature of the pot is greater than or equal to a second temperature threshold before detecting whether the temperature of the pot is greater than or equal to the first temperature threshold, wherein the second temperature threshold is less than the first temperature threshold.

[0152] For example, the second temperature threshold can be 250 degrees.

[0153] The purpose of determining whether the temperature of the pot is greater than or equal to the second temperature threshold is to determine whether a prompt needs to be given to the user.

[0154] If the temperature of the pot is greater than or equal to the second temperature threshold, it indicates that a prompt needs to be given to the user, at which time voice prompt information can be generated to remind the user that the pot is in an empty burning state.

[0155] If the temperature of the pot is not greater than or equal to the second temperature threshold, it indicates that a prompt does not need to be given to the user, at which time it can be continued to determine whether the temperature of the pot is greater than or equal to the second temperature threshold.

[0156] It can be understood that, by comparing the real-time temperature of the pot with the preset second temperature threshold, the smoke machine or the cloud platform can assess whether a safety prompt needs to be given to the user. Once the temperature of the pot reaches or exceeds this threshold (for example, 250 degrees), the smoke machine or the cloud platform will immediately determine that the pot is in an empty burning state and the temperature is rapidly rising, so a warning needs to be given to the user. At this time, the smoke machine or the cloud platform will generate voice prompt information to attract the user's attention and prevent the pot from causing safety hazards due to long-term unattended. Conversely, if the temperature of the pot remains below the second temperature threshold, the smoke machine or the cloud platform will consider that there is no need to urgently prompt the user, but will continue to monitor the temperature of the pot to ensure that appropriate measures can be taken quickly when necessary.

[0157] In this step, different execution subjects have different ways of playing the voice prompt information after generating the voice prompt information. For example, in the case of the hood, the way to play the voice prompt information may be, for example, to play by using the built-in voice module, or to play by controlling other voice playing devices in communication connection with the hood.

[0158] In the case of the cloud platform, the way to play the voice prompt information may be, for example, to play by controlling the voice module of the hood, or to play by controlling other voice playing devices. The present application does not make special limitations on this.

[0159] S407: sending a first fire-off instruction to the stove, the first fire-off instruction being used to instruct the stove to turn off the fire.

[0160] The purpose of sending the first fire-off instruction to the stove in this step is to prevent the temperature of the pot from being too high in the case of empty burning, thereby causing safety hazards of the stove and the pot itself.

[0161] It can be understood that when the stove is in the fire-on state, but there is no cooking object in the pot and the temperature of the pot is too high, this situation is easy to cause a fire or cause damage to the pot and even the stove. Therefore, in order to effectively prevent the occurrence of these safety hazards, the hood or the cloud platform needs to send a first fire-off instruction to the stove to ensure the safety of the cooking environment and the integrity of the stove and the pot.

[0162] S408: sending a first minimum fire instruction to the stove, the first minimum fire instruction being used to instruct the stove to adjust the fire to the minimum value.

[0163] When it is determined according to the first image that there is no pot on the stove, it usually means that the user may have forgotten to place the pot during cooking, or has removed the pot from the stove. In this case, if the stove continues to work at the original fire, there will be a great safety hazard, because the dry burning of the stove may quickly accumulate high temperature, thereby causing a fire.

[0164] Therefore, in order to timely respond to this potential risk, it is necessary to send a first minimum fire instruction to the stove to ensure that the flame on the stove is adjusted to the minimum fire state, thereby reducing the heat generated by the dry burning of the stove and effectively reducing the risk of fire caused by high temperature, ensuring the safety of the kitchen environment.

[0165] For example, during the cooking process of a stew, the user suddenly realizes that the surface of the stove is stained with oil or food residue, and in order to keep the kitchen clean and the stove hygienic, the user decides to clean the stove first. Therefore, the user safely removes the pot being heated from the stove to be able to clean the surface of the stove. At this time, the hood or the cloud platform obtains a first image by taking a photo and immediately analyzes and judges that there is no pot on the stove. In order to timely respond to this potential risk, the hood or the cloud platform immediately sends a first minimum fire instruction to the stove to control the stove to adjust the flame to the minimum fire state, thereby reducing the heat generated by the stove when dry burning, effectively reducing the risk of fire caused by high temperature, and ensuring the safety of the kitchen environment.

[0166] S409: After sending the first minimum fire instruction to the stove, a second image obtained by taking a photo of the stove is obtained at a first time.

[0167] The first time may be 20S, 1min or 2min, which is not limited in the present application.

[0168] It can be understood that when the stove is determined to be in a dry burning state, in order to prevent danger and waste energy, the hood or the cloud platform will enter a waiting period, and after the corresponding time of the waiting period is reached (i.e., after the first time is reached), a second image of the stove will be re-obtained in order to determine whether the stove changes from the dry burning state to the heating state according to the second image.

[0169] S410: Determine whether there is a pot on the stove in the second image; if yes, execute step S412; if no, execute step S411.

[0170] The purpose of this step is to determine whether the stove changes from the dry burning state to the heating state.

[0171] It can be understood that the heating state means that during the cooking process, the user places the pot above the stove so that the flame of the stove heats the pot. Therefore, by using the second image as a judgment factor to determine whether there is a pot on the stove, it can be determined whether the user has placed the pot above the stove again after the stove is in the dry burning state, so that the pot returns to the heating state.

[0172] If there is no pot on the stove in the second image, it means that the stove has not changed from the dry burning state to the heating state, and at the same time, it also means that the stove is still in the dry burning state. Therefore, a second fire-off instruction can be sent to the stove.

[0173] If there is a pot on the cooktop in the second image, it indicates that the cooktop has changed from the dry burning state to the heating state, and also indicates that the cooktop is not in the dry burning state, so the first recovery instruction can be sent to the cooktop.

[0174] For example, during the cooking of a stew, the user finds signs of burning on the bottom of the pot, so he takes the pot off the cooktop for cleaning and puts it back over the cooktop after cleaning. At this time, the range hood or cloud platform obtains a second image by taking a photo and immediately analyzes and judges that the pot has been placed back on the cooktop. After recognizing this change, it is confirmed that the cooktop has changed from the previous dry burning state to the heating state. Therefore, in order to restore the cooking process, the range hood or cloud platform immediately sends the first recovery instruction to the cooktop to control the cooktop to increase the flame to an appropriate cooking firepower, thereby ensuring the continuity of cooking and uniform heating of the food.

[0175] S411: Send a second fire-off instruction to the cooktop, the second fire-off instruction being used to instruct the cooktop to turn off the fire.

[0176] The purpose of this step is to avoid the cooktop being in the dry burning state for a long time.

[0177] It can be understood that when the cooktop operates according to the minimum fire instruction for a period of time and it is determined that the user does not place the pot over the cooktop during this period of time, it means that the user does not place the pot over the cooktop for a long time, and therefore, in order to avoid the cooktop being in the dry burning state for a long time, a second fire-off instruction needs to be sent to the cooktop to instruct the cooktop to turn off the fire.

[0178] S412: Send a first recovery instruction to the cooktop, the first recovery instruction being used to instruct the cooktop to increase the firepower.

[0179] The purpose of this step is to avoid the firepower being too small to meet the use requirements of the pot.

[0180] It can be understood that when the cooktop operates according to the minimum fire instruction for a period of time and it is determined that the user places the pot over the cooktop during this period of time, it means that the user places the pot over the cooktop during this period of time, and therefore, in order to avoid the firepower being too small to meet the use requirements of the pot, a first recovery instruction needs to be sent to the cooktop to instruct the cooktop to increase the firepower.

[0181] S413: Obtain a third image obtained by taking a photo of the cooktop.

[0182] The purpose of this step is to obtain a real-time image of the pot in order to process the cooktop according to the real-time image.

[0183] It can be understood that when the pot exists above the stove and the food to be cooked exists in the pot, in order to ensure the safety of the cooking process, the hood or the cloud platform will take a photo of the pot, thereby obtaining the real-time image of the pot, that is, the third image.

[0184] Optionally, different execution subjects have different ways of obtaining the third image of the stove. For example, in the case of the execution subject being the hood, the third image can be obtained by the hood taking a photo by using its built-in camera, and in the case of the execution subject being the cloud platform, the third image can be obtained by the cloud platform controlling the hood to take a photo by using its built-in camera and receiving the image returned by the hood, or by the cloud platform controlling other cameras to take a photo and receiving the image returned by the other cameras. The present application does not make special limitations on this.

[0185] S414: If the pot in the third image is in the boiling-over state, a third fire-off instruction is sent to the stove, and the third fire-off instruction is used to instruct the stove to turn off the fire.

[0186] In the case where it is determined according to the third image that the pot has been in the boiling-over state, in order to avoid the pot continuing to boil over and possibly causing danger or inconvenience, the third fire-off instruction needs to be sent to the stove to instruct the stove to turn off the fire.

[0187] It can be understood that when it is identified through analysis of the third image that the pot has been in the boiling-over state, in order to prevent the liquid or food in the pot from continuing to overflow, which may cause fire, scalding and other dangerous situations, or cause inconvenience in cleaning the kitchen, the hood or the cloud platform will immediately send the third fire-off instruction to the stove to instruct the stove to turn off the fire source and stop heating, thereby curbing the continuation of the boiling-over phenomenon and ensuring the safety and cleanliness of the kitchen environment.

[0188] In this step, the hood or the cloud platform may, for example, first identify the third image to determine whether the pot in the third image is in the boiling-over state. Then, when it is determined that the pot is in the boiling-over state, the hood or the cloud platform sends the third fire-off instruction to the stove.

[0189] S415: If the pot in the third image is in the boiling-over state, a third fire-off instruction is sent to the stove, and the third fire-off instruction is used to instruct the stove to turn off the fire.

[0190] In the case where it is determined according to the third image that the pot has been in the boiling-over state, in order to avoid the pot continuing to boil over and possibly causing danger or inconvenience, the third fire-off instruction needs to be sent to the stove to instruct the stove to turn off the fire.

[0191] It can be understood that when the pot is identified to be about to reach the critical state of pot boiling over by analyzing the third image, in order to prevent the liquid or food in the pot from boiling over, the hood or the cloud platform will immediately send a second minimum fire instruction to the stove to instruct the stove to automatically adjust its fire output to the minimum value, thereby slowing down the heating speed of the liquid or food in the pot, so as to avoid the occurrence of pot boiling over.

[0192] S416: If the pot in the third image is in a non-pot boiling over state, the image obtained by photographing the stove again is taken as a new third image to repeat the step.

[0193] Wherein, in order to avoid the pot from boiling over, when it is determined that the pot is in a non-pot boiling over state according to the third image, the stove will be photographed again to obtain a new third image.

[0194] It can be understood that when the pot is identified to be in a safe state of non-pot boiling over by analyzing the third image, in order to prevent the future possible pot boiling over phenomenon, the hood or the cloud platform will photograph the stove and the pot on it again to obtain the latest third image, so as to monitor the changes of the pot and the cooking process in real time.

[0195] S417: After the second minimum fire instruction is sent to the stove, a fourth image obtained by photographing the stove is acquired after a second time.

[0196] Wherein, the second time can be 1 min, 3 min or 5 min. The present application does not make special limitation on this.

[0197] It can be understood that after it is determined that the pot on the stove is about to boil over, the hood or the cloud platform will immediately send a second minimum fire instruction to the stove. Subsequently, the hood or the cloud platform enters a waiting period, i.e. after the second time ends, the stove is photographed again to obtain a fourth image, so as to determine whether the pot will boil over under the minimum fire of the stove according to the fourth image.

[0198] S418: Determine whether the pot in the fourth image is in a non-pot boiling over state; if yes, execute step S419; if no, execute step S420.

[0199] Wherein, the purpose of determining whether the pot in the fourth image is in a non-pot boiling over state is to determine whether the pot will boil over under the minimum fire of the stove.

[0200] If the pot in the fourth image is in a non-pot boiling over state, it indicates that the pot does not boil over under the minimum fire of the stove, and at this time, a second recovery instruction can be sent to the stove.

[0201] If the pot in the fourth image is not in the no-overflow state, it indicates that the pot on the stove is in an overflow state at the minimum fire, at which time a fourth fire-off instruction can be sent to the stove.

[0202] S419: a second recovery instruction is sent to the stove, and the second recovery instruction is used to instruct the stove to increase the fire.

[0203] It can be understood that when the stove is stably operated for a period of time according to the second minimum fire instruction, and it is determined that the food being cooked in the pot on the stove will not overflow during this period of time, it indicates that the current cooking process is safe and stable. At this time, in order to speed up the cooking process of the food and improve the cooking efficiency, a second recovery instruction needs to be sent to the stove to instruct it to increase the fire, so as to complete the cooking of the food as soon as possible under the premise of safety.

[0204] It can be understood that when the stove is stably operated for a period of time according to the second minimum fire instruction, and it is determined that the food being cooked in the pot on the stove will still overflow during this period of time, it indicates that the current cooking process is unstable and there is a safety hazard. At this time, in order to ensure the safety of the cooking environment and avoid further overflow risk, a fourth fire-off instruction needs to be sent to the stove.

[0205] S420: a fourth fire-off instruction is sent to the stove, and the fourth fire-off instruction is used to instruct the stove to turn off the fire.

[0206] It can be understood that when the stove is stably operated for a period of time according to the second minimum fire instruction, and it is determined that the food being cooked in the pot on the stove will still overflow during this period of time, it indicates that the current cooking process is unstable and there is a safety hazard. At this time, in order to ensure the safety of the cooking environment and avoid further overflow risk, a fourth fire-off instruction needs to be sent to the stove.

[0207] It can be understood that when the stove is stably operated for a period of time according to the second minimum fire instruction, and it is determined that the food being cooked in the pot on the stove will still overflow during this period of time, it indicates that the current cooking process is unstable and there is a safety hazard. At this time, in order to ensure the safety of the cooking environment and avoid further overflow risk, a fourth fire-off instruction needs to be sent to the stove.

[0208] The stove control method provided by the embodiment first acquires a first image by taking a picture when the stove is in a state of having a fire, then performs image recognition processing on the first image to obtain a first recognition result of the first image, and then judges whether there is a pot on the stove according to the first recognition result. If it is determined according to the first recognition result that the pot exists, it is further analyzed whether the pot contains cooking food. If the pot exists and the cooking food in the pot is missing, the temperature of the pot is acquired, and when the temperature is greater than or equal to a first temperature threshold, a first fire-off instruction is sent to the stove to prevent dry burning. If the pot contains cooking food, the cooking state monitoring is entered, it is analyzed whether the pot is in an overflow state, an about-to-overflow state or a no-overflow state by taking a picture again, and the fire of the stove is adjusted accordingly to ensure the safety and efficiency of the cooking process.

[0209] If it is determined according to the first identification result that the pot does not exist, a minimum fire instruction is sent to the stove. Then, at the first time after sending the minimum fire instruction, a second image of the stove area is acquired again, and the necessary adjustment of the stove fire is made according to the information of the new image. This method not only solves the technical problem of automatic adjustment of the stove fire, but also greatly reduces the attention burden of the user, ensuring kitchen safety even when the user is busy or distracted, thereby significantly improving the safety protection capability and use convenience of the home kitchen.
