[0027] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0028] It should be noted that the terms "candidate", "target", "first", "second", "third", "fourth", "fifth", "sixth", "seventh", "eighth", "ninth", "tenth", "eleventh", "twelfth", "thirteenth", "fourteenth", "fifteenth", "sixteenth", "seventeenth", "eighteenth", "nineteenth", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the terms used in this way are interchangeable where appropriate so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units that are not explicitly listed or inherent to these processes, methods, products or apparatus.

[0029] Existing gas stoves have the disadvantage of low intelligent fire control, which is mainly reflected in two aspects:

[0030] First, the gas stove needs to be supervised by the user throughout the cooking process, which makes it impossible for the user to leave the kitchen freely to do other things during the cooking process, greatly limiting people's life convenience and resulting in high labor costs in the cooking process.

[0031] Secondly, users manually control the heat based on their cooking experience. While experienced chefs may be able to accurately judge when to increase and decrease the heat, this presents a significant challenge for novice cooks. This inability to accurately control the heat can lead to poorly tasting dishes. For example, stewing with too high a heat can cause the liquid to evaporate too quickly, leaving the ingredients dry and tough. Frying with too high a heat can overcook the food, producing unhealthy carcinogens and resulting in a poor-tasting dish.

[0032] Example 1

[0033] Figure 1 This is a flow chart of a gas stove firepower control method provided in the first embodiment of the present invention. This embodiment is applicable to the case of automatically controlling the cooking firepower during the cooking process. The method can be applied to a gas stove control system, which includes an information interaction module, a data acquisition module, a cooking firepower determination module, and a gas stove module. The gas stove module includes a target pot. Figure 1 As shown, the method includes:

[0034] S101. Determine a target cooking mode according to a cooking mode selected by a target user through an information interaction module, and determine candidate cooking stages included in the target cooking mode according to the target cooking mode.

[0035] The information interaction module is a functional module within the gas stove control system for interacting with the user. Specifically, the information interaction module can output information to the target user, for example, by voice broadcast or through graphic visualization. Correspondingly, the target user can also input information into the information interaction module, for example, by voice or through touch. The target user refers to the user currently interacting with the information interaction module, i.e., the user currently having a cooking need.

[0036] The gas stove control system is pre-configured with at least one candidate cooking mode. The information interaction module outputs cooking mode selection information to a target user, allowing the target user to select a cooking mode based on the cooking mode selection information and to determine a target cooking mode from the candidate cooking modes. The candidate cooking modes refer to cooking modes currently supported by the gas stove control system, including but not limited to boiling, stir-frying, and deep-frying. This embodiment does not limit the specific types of candidate cooking modes. It is understood that the candidate cooking modes can be updated in the gas stove control system based on the actual cooking needs of the general public, such as by adding or deleting candidate cooking modes in the gas stove control system via OTA (Over-The-Air) updates.

[0037] In the information interaction module, each candidate cooking mode is pre-configured with at least one candidate cooking stage. A candidate cooking stage is a division of the cooking process of each candidate cooking mode. For example, assuming the candidate cooking mode is "boil mode," its candidate cooking stages include, but are not limited to, a "hot water stage" and a "cooking stage."

[0038] In one embodiment, the information interaction module is configured as a touch-sensitive display screen. The information interaction module visually displays candidate cooking modes to a target user. The target user selects a cooking mode by touching any candidate cooking mode displayed by the information interaction module based on their cooking needs. For example, if the target user requires a "cooking mode," the target user selects the cooking mode by touching the relevant graphic and text for the "cooking mode" displayed by the information interaction module.

[0039] Furthermore, the information interaction module responds to the target user's touch-sensitive cooking mode selection and sets the candidate cooking mode selected by the target user as the target cooking mode. For example, if the target user touches and selects the relevant image and text of "cooking mode", "cooking mode" will be set as the target cooking mode.

[0040] In another embodiment, the information interaction module is configured as a device with voice interaction capabilities, such as a smart speaker. The information interaction module announces each candidate cooking mode to a target user via voice, and the target user then selects a cooking mode based on their cooking needs via voice communication with the information interaction module. Furthermore, the information interaction module responds to the target user's voice selection of a cooking mode and determines a target cooking mode from the candidate cooking modes based on the voice recognition results.

[0041] After determining the target cooking mode, the information interaction module determines at least one candidate cooking stage included in the target cooking mode according to the target cooking mode.

[0042] S102: acquiring target characteristic data of the target cookware during the cooking process through a data acquisition module and / or analyzing the data.

[0043] The data acquisition module is a functional module within the gas stove control system that collects target characteristic data generated by the target cookware during the cooking process. Specifically, the data acquisition module includes a temperature sensing component and a camera component. The temperature sensing component is used to collect temperature data generated by the target cookware during the cooking process. When the data acquisition module integrates a data analysis module, it can also calculate heating rate data using the temperature data analysis module's software. The data acquisition module used in this embodiment includes the aforementioned temperature data analysis module. In other processing methods, this temperature data analysis module can also be integrated into the cooking power determination module. In this embodiment, the camera component is used to collect image data generated by the target cookware during the cooking process. In other words, the target characteristic data includes temperature data, heating rate data, and / or image data. The target characteristic data can be characteristic data within the target cookware. Specifically, the temperature data refers to the temperature data within the target cookware, the heating rate data refers to the heating rate data within the target cookware, and the image data refers to the image data within the target cookware.

[0044] In one embodiment, when the target user turns on the ignition function of the gas stove module, the gas stove module heats the target pot according to the default initial cooking fire. Correspondingly, when the target user turns on the ignition function of the gas stove module, the data acquisition module starts working to collect and / or analyze the target feature data generated by the target pot during the cooking process.

[0045] Optionally, the specific types of target feature data collected by the data acquisition module include at least one of the following: temperature data, heating rate data, image data, temperature data and heating rate data, temperature data and image data, heating rate data and image data, and temperature data, heating rate data and image data.

[0046] S103: The cooking power determination module determines a target cooking stage from candidate cooking stages included in the target cooking mode according to the target feature data, and determines a target cooking power according to the target cooking stage.

[0047] Among them, the cooking fire power determination module is a control module in the gas stove control system for automatically controlling the cooking fire power.

[0048] The cooking power determination module pre-assigns a corresponding candidate cooking power for each candidate cooking stage of each candidate cooking mode. This means that when the gas stove control system determines that it is currently in any candidate cooking stage of a candidate cooking mode, it can determine the corresponding candidate cooking power, thereby achieving intelligent and automatic cooking power control. The candidate cooking power refers to the control of the heat source intensity of the gas stove module during the cooking process, and the unit of the candidate cooking power can be selected in kilowatts.

[0049] In one embodiment, the target cooking mode is transmitted to the cooking power determination module via the information exchange module, and the target feature data is transmitted to the cooking power determination module via the data acquisition module. Furthermore, the cooking power determination module determines the target cooking stage from the candidate cooking stages included in the target cooking mode based on the target feature data and the association between the candidate feature data and the candidate cooking stages. For example, assuming the target cooking mode is "stir-fry mode," the candidate cooking stages included in the "stir-fry mode" are determined to be the "heating stage," the "sauté stage," and the "stir-fry stage." Assuming the temperature data is T, and there is a preset association between the temperature data T and the "sauté stage," the "sauté stage" is determined to be the target cooking stage.

[0050] Furthermore, the cooking power determination module determines the target cooking power from the candidate cooking powers according to the target cooking stage and the association between the candidate cooking stages and the candidate cooking powers.

[0051] For example, assuming that the target cooking stage is the "sauté stage", and there is an association relationship between the "sauté stage" and the "candidate cooking firepower 5kw", the target cooking firepower is determined to be "5kw".

[0052] Optionally, when the target cooking mode is a boiling mode, the candidate cooking stages include a hot water stage and a boiling stage; when the target cooking mode is a frying mode, the candidate cooking stages include a hot pot stage, a hot oil stage and a frying stage; when the target cooking mode is a stir-fry mode, the candidate cooking stages include a heating stage, a sautéing stage and a stir-frying stage.

[0053] S104: heating the target pot by using the target cooking power through the gas stove module.

[0054] Among them, the gas stove module is a functional module in the gas stove control system used to provide a heat source to heat the target pot.

[0055] In one embodiment, the cooking power determination module generates a cooking power control instruction based on the target cooking power and transmits the cooking power control instruction to the gas stove module. Furthermore, the gas stove module, in response to the cooking power control instruction, heats the target cookware at the target cooking power. For example, if the current cooking power of the gas stove module is 3 kW and the target cooking power is 5 kW, the gas stove module adjusts the cooking power from 3 kW to 5 kW.

[0056] The embodiment of the present invention determines the target cooking stage in the target cooking mode based on the target characteristic data of the target cookware obtained by collecting and / or analyzing the target cooking stage, and then automatically controls the firepower according to the target cooking stage, thereby improving the intelligence level of cooking firepower control. On the one hand, it can reduce the manpower cost invested in the cooking process, and on the other hand, it can alleviate the problem of untimely firepower control, thereby further ensuring the taste of the cooked ingredients.

[0057] Example 2

[0058] Figure 2 This is a flow chart of a method for controlling the firepower of a gas stove provided in the second embodiment of the present invention. This embodiment further optimizes and expands the above embodiment and can be combined with the above optional implementations. Figure 2 As shown, the method includes:

[0059] S201: Determine a target cooking mode according to the cooking mode selection implemented by the target user through an information interaction module, and determine candidate cooking stages included in the target cooking mode according to the target cooking mode.

[0060] S202: Acquire target characteristic data of the target cookware during the cooking process through a data acquisition module.

[0061] The target characteristic data includes temperature data, heating rate data and / or image data.

[0062] S203: When the target cooking mode is the boiling mode, determine whether the first ingredient exists in the target cookware according to the image data by using a cooking power determination module.

[0063] The first ingredient refers to any ingredient placed in the target cookware, rather than a specific ingredient.

[0064] In one embodiment, a data acquisition module collects image data of a target cookware during the cooking process and transmits the image data to a cooking power determination module. If the target cooking mode is a boil mode, the cooking power determination module performs entity detection on the image data using an entity detection algorithm and determines whether the first ingredient is in the target cookware based on the entity detection result.

[0065] S204: When the first ingredient does not exist in the target cookware, determine the target cooking stage as the hot water stage; when the first ingredient exists in the target cookware, determine the target cooking stage as the boiling stage.

[0066] In one embodiment, if it is determined that the first ingredient is not present in the target cookware, this indicates that the target user has not yet added the ingredient to the target cookware. Therefore, it can be determined that the target user's intention is to heat the water in the target cookware, and thus the target cooking stage is determined to be the hot water stage. If it is determined that the first ingredient is present in the target cookware, this indicates that the target user has already added the ingredient to the target cookware. Therefore, it can be determined that the target cooking stage is the cooking stage.

[0067] When the target cooking mode is the boiling mode, the cooking power determination module determines whether the first ingredient is in the target pot according to the image data; when the first ingredient is not in the target pot, the target cooking stage is determined to be the hot water stage; when the first ingredient is in the target pot, the target cooking stage is determined to be the boiling stage. The beneficial effects are:

[0068] Firstly, it can determine in real time through image data whether the target pot contains the first ingredient, and automatically distinguish between the "hot water stage" and the "cooking stage", thus achieving the effect of automatic identification of the cooking stage and improving the intelligence level of the cooking process.

[0069] Secondly, the target user only needs to put in the ingredients, and the gas stove control system can automatically identify the target cooking stage without the need for manual settings by the target user, which simplifies the manual operation steps and enhances the user experience of the target user.

[0070] S205: Determine the target cooking power according to the target cooking stage.

[0071] Optionally, a target cooking power is determined according to a target cooking stage, including:

[0072] S2051: When the target cooking stage is the hot water stage, the cooking power determination module determines whether the water in the target pot is in a boiling state according to the temperature data.

[0073] In one embodiment, a data acquisition module collects temperature data of a target cookware during the cooking process and transmits the temperature data to a cooking power determination module. If the target cooking stage is determined to be the hot water stage, the cooking power determination module compares the temperature data with the boiling point of water and determines whether the water in the target cookware is boiling based on the comparison result.

[0074] In addition, in other methods, the cooking fire power determination module may also be used to determine whether the water is in a boiling state based on the image data.

[0075] S2052: When it is determined that the water in the target pot is in a boiling state, determine the target cooking power to be a first cooking power.

[0076] In one embodiment, if the cooking power determination module determines that the temperature data is equal to the boiling point of water, the water in the target pot is determined to be boiling. If the water in the target pot is determined to be boiling, the target cooking power is determined to be the second cooking power.

[0077] S2053: When it is determined that the water in the target pot is not in a boiling state, determine the target cooking power to be a first cooking power.

[0078] The second cooking power is smaller than the first cooking power, and the first cooking power is the maximum cooking power of the gas stove module.

[0079] In one embodiment, if the cooking power determination module determines that the temperature data is less than the boiling point of water, it is determined that the water in the target pot is not boiling. If it is determined that the water in the target pot is not boiling, the target cooking power is determined to be the second cooking power.

[0080] Optionally, the second cooking power range is set to 1.8 to 2.5 kW.

[0081] When the target cooking stage is the hot water stage, the cooking power determination module determines whether the water in the target pot is in a boiling state based on the temperature data; when it is determined that the water in the target pot is in a boiling state, the target cooking power is determined to be a second cooking power; when it is determined that the water in the target pot is not in a boiling state, the target cooking power is determined to be a first cooking power; wherein the second cooking power is less than the first cooking power, and the first cooking power is the maximum cooking power of the gas stove module. The beneficial effects are:

[0082] First, if the maximum cooking power is continued, the water in the target pot may boil violently, causing the soup to overflow and extinguish the flame of the gas stove module. Maintaining a gentle boiling by using a second cooking power that is lower than the maximum cooking power can reduce such safety hazards and improve cooking safety.

[0083] Secondly, once the water boils, continuing to use the maximum cooking power will not raise the water temperature, but will accelerate the evaporation of water vapor, resulting in gas waste. Therefore, switching to a lower second cooking power can maintain the boiling state while reducing gas consumption and optimizing energy efficiency.

[0084] Third, continuously cooking at maximum power can cause local overheating at the bottom of the target pot, accelerating metal fatigue. Dynamically lowering the power can reduce thermal stress and extend the service life of the target pot and gas stove module.

[0085] Fourthly, the traditional cooking process requires manual observation of the boiling state and control of the firepower. This embodiment automatically controls the cooking firepower through temperature data, simplifies the manual operation steps, and enhances the user experience of the target users.

[0086] S206: Heat the target pot with the target cooking power through the gas stove module.

[0087] Optionally, the method further includes:

[0088] The cooking power determination module determines a first duration of the first food floating on the water surface according to the image data; when the first duration is greater than or equal to a first time threshold, the target cooking power is determined to be zero.

[0089] Among them, the first time threshold can be set and adjusted according to actual business needs.

[0090] In one embodiment, a cooking fire power determination module uses a preset image recognition algorithm to determine a first duration that the first ingredient floats on the water surface, and numerically compares the first duration with a first time threshold. If it is determined that the first duration is less than the first time threshold, it indicates that the first ingredient is not yet cooked, and no operation is performed at this time; if it is determined that the first duration is greater than or equal to the first time threshold, it indicates that the first ingredient is cooked, and the heating function of the gas stove module is automatically turned off, that is, the target cooking fire power is determined to be zero.

[0091] The cooking power determination module determines a first duration of the first food floating on the water surface based on the image data; and when the first duration is greater than or equal to a first time threshold, determines the target cooking power to be zero. The beneficial effects are:

[0092] First, it avoids the problem of overheating caused by visual misjudgment during the traditional cooking stage, ensuring that the first ingredient reaches the best edible state.

[0093] Secondly, continuing to heat ingredients after they are fully cooked during the cooking stage will waste energy. This solution can reduce energy consumption by resetting the cooking fire to zero.

[0094] Thirdly, if the water dries up during the cooking stage and no one is on duty, it is easy to cause a fire. This safety hazard can be avoided by automatically resetting the cooking fire to zero.

[0095] Optionally, the method further includes:

[0096] The cooking power determination module determines whether the target user has covered the target pot according to the image data; if so, the target cooking power is determined to be the minimum cooking power of the gas stove module.

[0097] In one embodiment, the cooking power determination module uses a preset behavior detection algorithm to determine whether the target user has covered the target pot based on the image data. If it is determined that the target user has covered the target pot, it indicates that the target user wants to cook it slowly over low heat. Therefore, the target cooking power is determined to be the minimum cooking power of the gas stove module.

[0098] The cooking power determination module determines whether the target user has covered the target pot based on the image data; if so, the target cooking power is determined to be the minimum cooking power of the gas stove module. The beneficial effects are:

[0099] First, after covering the food, use the minimum cooking fire to meet the temperature requirements of cooking methods such as slow stewing and braising, so as to avoid high temperature from destroying the nutritional structure of the food.

[0100] Secondly, the minimum cooking power is automatically adjusted after the lid is added, which can reduce the tedious steps of manually controlling the cooking power and improve the cooking experience of the target users.

[0101] Thirdly, when it is detected that the target user has covered the target pot, the cooking power is automatically switched to the minimum, which can avoid the waste of heat energy caused by steam evaporation.

[0102] In addition, in cooking mode, the water boiling point can be adjusted according to the geographical location, and when cooking with other soup bases, the corresponding value of the water boiling point can be corrected accordingly.

[0103] Example 3

[0104] Figure 3 This is a flowchart of a cooking power determination method provided by the third embodiment of the present invention. This embodiment further optimizes and expands the step of "determining the target cooking power corresponding to the target cooking stage" in the above embodiment, and can be combined with the above optional implementation methods. Figure 3 As shown, the method includes:

[0105] S301: When the target cooking stage is the boiling stage, determine, by a cooking power determination module, whether a first ingredient type of a first ingredient can be identified according to image data.

[0106] The first ingredient type refers to the ingredient type corresponding to the first ingredient, and does not specifically refer to a certain ingredient type.

[0107] In one embodiment, a data acquisition module collects image data of a target cookware during the cooking process and transmits the image data to a cooking power determination module. The cooking power determination module employs a preset image recognition method, including but not limited to a convolutional neural network model method, a sparsification and lightweight model method, etc., to identify the type of the first ingredient based on the image data.

[0108] S302: When the first ingredient type cannot be identified, determine the temperature difference data between the temperature data and the boiling point of water by a cooking power determination module.

[0109] S303: When the temperature difference data is less than the temperature difference threshold, determine the target cooking power as the second cooking power.

[0110] S304: When the temperature difference data is greater than or equal to the temperature difference threshold, determine the target cooking power to be the third cooking power.

[0111] The third cooking power is greater than the second cooking power.

[0112] In one embodiment, when the cooking power determination module cannot identify the first ingredient type according to the image data, a general cooking power control method is triggered.

[0113] Specifically, the cooking power determination module determines the temperature difference between the temperature data and the boiling point of water, and compares the temperature difference with a preset temperature difference threshold. If the temperature difference is less than the temperature difference threshold, the target cooking power is determined to be the second cooking power. If the temperature difference is greater than or equal to the preset temperature difference threshold, the target cooking power is determined to be the third cooking power.

[0114] Optionally, the third cooking power is set to be greater than or equal to 3 kW, and the second cooking power is set to a range of 1.8 to 2.5 kW. The temperature difference threshold is selected from 3 to 10°C. The temperature difference data is set to be positive, that is, ΔT = |T0-T|, where ΔT is the temperature difference data, T0 is the boiling point of water, and T is the temperature data.

[0115] When the target cooking stage is the boiling stage, the cooking power determination module determines whether the first ingredient type of the first ingredient can be identified based on the image data; when the first ingredient type cannot be identified, the cooking power determination module determines the temperature difference data between the temperature data and the boiling point of water; when the temperature difference data is less than a temperature difference threshold, the target cooking power is determined to be a second cooking power; when the temperature difference data is greater than or equal to the temperature difference threshold, the target cooking power is determined to be a third cooking power; wherein the third cooking power is greater than the second cooking power, the beneficial effect is:

[0116] Firstly, when the type of the first ingredient cannot be identified, the cooking fire power can still be controlled by a general cooking fire power control method, thereby ensuring the stability and reliability of the automatic cooking fire power control.

[0117] Secondly, when the temperature difference data is large, a larger third cooking power is used for heating to ensure that the water can boil as quickly as possible. When the temperature difference data is small, a smaller second cooking power is used for heating to keep the first ingredient cooked in a boiling state, thereby improving the intelligence of the cooking process.

[0118] Optionally, after the cooking power determination module determines whether the first ingredient type of the first ingredient can be identified according to the image data, the method further includes:

[0119] S3011: When the first ingredient type is identified as the target ingredient type, determine whether the water in the target pot is in a boiling state according to the temperature data through the cooking power determination module.

[0120] Among them, the target food types are food types that need to add water during the cooking stage, including but not limited to dumplings, wontons, beef and mutton, etc.

[0121] In one embodiment, when the cooking power determination module identifies the first ingredient type as the target ingredient type, the cooking power determination module compares the temperature data with the boiling point of water. If the temperature data is determined to be equal to the boiling point of water, the water in the target cookware is determined to be boiling; if the temperature data is determined to be less than the boiling point of water, the water in the target cookware is determined to be not boiling.

[0122] S3012: When it is determined that the water in the target pot is in a boiling state, determine the target cooking power to be a second cooking power within a first time period, and determine the target cooking power to be a fourth cooking power after the first time period has expired.

[0123] The fourth cooking power is smaller than the second cooking power. The first time period can be set and adjusted according to actual needs, such as setting the first time period to be within 30s to 180s.

[0124] In one embodiment, when it is determined that water in the target pot is in a boiling state, the target cooking power is determined to be the second cooking power within a first time period, and it is determined whether the duration of the second cooking power exceeds the first time period. After it is determined that the duration exceeds the first time period, the target cooking power is determined to be the fourth cooking power.

[0125] Optionally, the fourth cooking power is set to within 0.2 to 0.5 kW.

[0126] S3013. Determine, through the cooking power determination module, whether the temperature data is less than or equal to the first temperature threshold; if so, determine the target cooking power to be the third cooking power until the water in the target pot is in a boiling state.

[0127] Among them, the first temperature threshold is lower than the boiling point of water and can be set and adjusted according to actual needs, such as setting the first temperature threshold to be within 80-90°C.

[0128] In one embodiment, the temperature data is numerically compared with the first temperature threshold by the cooking power determination module. When it is determined that the temperature data is less than or equal to the first temperature threshold, the target cooking power is determined to be the third cooking power until the cooking power determination module determines that the water in the target pot is in a boiling state.

[0129] By identifying the first ingredient type as the target ingredient type, determining whether the water in the target pot is in a boiling state according to the temperature data through the cooking power determination module; wherein the target ingredient type is the ingredient type that needs to add water during the cooking stage; when it is determined that the water in the target pot is in a boiling state, determining the target cooking power to be a second cooking power within a first time period, and determining the target cooking power to be a fourth cooking power after exceeding the first time period; wherein the fourth cooking power is less than the second cooking power; determining whether the temperature data is less than or equal to the target cooking power through the cooking power determination module If the target cooking power is equal to the first temperature threshold, if so, the target cooking power is determined to be the third cooking power until the water in the target pot is in a boiling state. The beneficial effect is that: the target cooking power is the second cooking power during the first time period, and is switched to the fourth cooking power after the first time period to reduce the temperature in the pot. When the temperature data is less than or equal to the first temperature threshold, the target cooking power is increased until the pot boils again, and then switched back to the second cooking power. In this way, the effect of adding water midway during the cooking stage is simulated, which can achieve the effect of no need for supervision and can also ensure the cooking taste of ingredients that require adding water midway during the cooking stage.

[0130] Example 4

[0131] Figure 4 This is a flowchart of a cooking firepower determination method provided by the fourth embodiment of the present invention. This embodiment further optimizes and expands the above embodiment and can be combined with the above optional implementation methods. Figure 4 As shown, the method includes:

[0132] S401: Determine auxiliary feature data of a target cookware according to image data through a cooking power determination module.

[0133] The auxiliary feature data includes at least one of a bubble quantity value, a water volume change value, and a water height change value.

[0134] In one embodiment, the cooking power determination module uses a preset image recognition algorithm to determine at least one of the bubble quantity value, water volume change value, and water height change value in the target pot based on the image data.

[0135] S402: The cooking power determination module determines whether the target pot is overflowing according to the auxiliary feature data.

[0136] In one embodiment, the cooking power determination module compares the bubble quantity value with a bubble quantity threshold value, and when it is determined that the bubble quantity value is greater than or equal to the bubble quantity threshold value, it is determined that the target pot is overflowing.

[0137] In another embodiment, the cooking fire power determination module compares the water volume change value with the water volume change threshold. When it is determined that the water volume change value is greater than or equal to the water volume change threshold, it is determined that the target pot is overflowing.

[0138] In another embodiment, the cooking fire power determination module compares the water height change value with the water height change threshold. When it is determined that the water height change value is greater than or equal to the water height change threshold, it is determined that the target pot is overflowing.

[0139] In another embodiment, the cooking fire power determination module numerically compares the bubble number value with the bubble number threshold, the water volume change value with the water volume change threshold, and the water height change value with the water height change threshold. When it is determined that the bubble number value is greater than or equal to the bubble number threshold, the water volume change value is greater than or equal to the water volume change threshold, and the water height change value is greater than or equal to the water height change threshold, it is determined that the target pot is overflowing.

[0140] S403: When it is determined that the target cookware is overflowing, the target cooking power is determined to be an anti-overflow cooking power.

[0141] Among them, the anti-overflow pot cooking power is zero, or the minimum cooking power of the gas stove module.

[0142] In one embodiment, when it is determined that the target pot has overflowed, the target cooking power is determined to be zero, or the target cooking power is determined to be the minimum cooking power of the gas stove module.

[0143] The cooking power determination module determines auxiliary feature data of the target pot based on the image data; wherein the auxiliary feature data includes at least one of a bubble quantity value, a water volume change value, and a water height change value; the cooking power determination module determines whether the target pot is overflowing based on the auxiliary feature data; if the target pot is overflowing, the target cooking power is determined to be an anti-overflow cooking power; wherein the anti-overflow cooking power is zero or the minimum cooking power of the gas stove module. The beneficial effects are:

[0144] First, when overflow occurs, immediately cut off the cooking fire or adjust it to the minimum cooking fire to avoid water extinguishing the flame and causing gas leakage, thereby improving cooking safety.

[0145] Secondly, the overflow phenomenon is comprehensively judged by the bubble quantity value, water volume change value and water height change value. Compared with relying on a single parameter to judge the overflow phenomenon, it can avoid misjudgment caused by wind blowing the pot wall, oil stain interference, etc., and ensure the accuracy and reliability of the overflow phenomenon judgment.

[0146] Example 5

[0147] Figure 5 This is a flowchart of a method for controlling the firepower of a gas stove provided by the fifth embodiment of the present invention. This embodiment further optimizes and expands the above embodiment and can be combined with the above optional implementations. Figure 5 As shown, the method includes:

[0148] S501: Determine a target cooking mode according to the cooking mode selection implemented by the target user through an information interaction module, and determine candidate cooking stages included in the target cooking mode according to the target cooking mode.

[0149] S502: Acquire target characteristic data of the target cookware during the cooking process through a data acquisition module.

[0150] The target characteristic data includes temperature data, heating rate data and / or image data.

[0151] S503: When the target cooking mode is the frying mode, the cooking power determination module determines whether the second ingredient exists in the target cookware according to the image data.

[0152] The second ingredient refers to any ingredient placed in the target cookware, rather than a specific ingredient.

[0153] In one embodiment, a data acquisition module collects image data of a target cookware during the cooking process and transmits the image data to a cooking power determination module. If the target cooking mode is frying, the cooking power determination module performs entity detection on the image data using an entity detection algorithm and determines whether the second ingredient is in the target cookware based on the entity detection result.

[0154] S504: If the second ingredient is present in the target cookware, determine that the target cooking stage is the frying stage; if the second ingredient is not present in the target cookware, determine, through the cooking firepower determination module, whether the heating rate data is greater than a first heating rate threshold.

[0155] The first temperature rise rate threshold can be set and adjusted according to actual business needs, such as setting the first temperature rise rate threshold to 25-35°C / 10s, or to the range.

[0156] In one embodiment, if the second ingredient is determined to be present in the target cookware, it indicates that the target user has already added the ingredient to the target cookware. Therefore, it can be determined that the target user's intention is to fry the ingredients, and thus the target cooking stage is determined to be the frying stage. If the second ingredient is determined not to be present in the target cookware, it indicates that the target user's intention is to heat the pan or oil, and further determination is required based on the heating rate data.

[0157] During the hot oil phase, the target pot contains a large amount of oil, which causes the pot to heat up more slowly, resulting in a lower heating rate. However, during the hot pot phase, the target pot contains less oil, which causes the pot to heat up more quickly, resulting in a higher heating rate. Therefore, the data acquisition module collects the target pot's heating rate data during the cooking process and transmits this data to the cooking power determination module. The cooking power determination module compares this data with a first heating rate threshold to determine whether it exceeds the threshold.

[0158] S505. When it is determined that the temperature rise rate data is greater than the first temperature rise rate threshold, the target cooking stage is determined to be the hot pot stage; when it is determined that the temperature rise rate data is less than or equal to the first temperature rise rate threshold, the target cooking stage is determined to be the hot oil stage.

[0159] In one embodiment, when it is determined that the heating rate data is greater than a first heating rate threshold, it indicates that the amount of oil added in the target cookware is small at this time, and the target cooking stage is determined to be the hot pot stage; when it is determined that the heating rate data is less than or equal to the first heating rate threshold, it indicates that the amount of oil added in the target cookware is large at this time, and the target cooking stage is determined to be the hot oil stage.

[0160] When the target cooking mode is the frying mode, the cooking power determination module determines, based on the image data, whether the second ingredient is in the target cookware; when the second ingredient is in the target cookware, the target cooking stage is determined to be the frying stage; when the second ingredient is not in the target cookware, the cooking power determination module determines whether the heating rate data is greater than a first heating rate threshold; when it is determined that the heating rate data is greater than the first heating rate threshold, the target cooking stage is determined to be the hot pot stage; when it is determined that the heating rate data is less than or equal to the first heating rate threshold, the target cooking stage is determined to be the hot oil stage. The beneficial effects are:

[0161] First, by using image data to determine in real time whether there is a second ingredient in the target pot, it can automatically distinguish between the "frying stage" and the "hot oil stage / hot pot stage", achieving the effect of automatic identification of the cooking stage and improving the intelligence level of the cooking process.

[0162] Secondly, by utilizing the difference in heating speed between the "hot oil stage" and the "hot pot stage", the first heating rate threshold is set to distinguish between the "hot oil stage" and the "hot pot stage", ensuring the accuracy and simulation of the automatic identification of the cooking stage.

[0163] Thirdly, the target user only needs to put in the ingredients, and the gas stove control system can automatically identify the target cooking stage without the need for manual settings by the target user, which simplifies the manual operation steps and enhances the user experience of the target user.

[0164] S506: Determine a target cooking power according to the target cooking stage, and heat the target pot with the target cooking power through the gas stove module.

[0165] Optionally, a target cooking power is determined according to a target cooking stage, including:

[0166] S5061: When the target cooking stage is the hot pot stage, determine the magnitude relationship between the temperature data and the second temperature threshold value through the cooking fire power determination module.

[0167] The second temperature threshold is determined based on the temperature of the target cookware after washing, when the inside of the cookware is substantially dry and free of water, such as setting the second temperature threshold to between 180°C and 200°C. Preferably, the second temperature threshold can be determined based on the material of the target cookware. For example, when the target cookware is a medical stone coated cookware, the second temperature threshold is set to 160°C; when the target cookware is an iron pot, the second temperature threshold is set to 210°C; when the target cookware is a coated frying pan, the second temperature threshold is set to 200°C; when the target cookware is a stainless steel pot, the second temperature threshold is set to 175°C, etc.

[0168] In one embodiment, when the target cooking stage is the hot pot stage, the temperature data is numerically compared with the second temperature threshold by the cooking power determination module to determine the magnitude relationship between the temperature data and the second temperature threshold.

[0169] S5062: When the temperature data is less than or equal to the second temperature threshold, determine the target cooking power to be the maximum cooking power of the gas stove module.

[0170] In one embodiment, when the cooking power determination module determines that the temperature data is less than or equal to the second temperature threshold, it indicates that the temperature inside the target cookware is low at this time, and the target cooking power is determined to be the maximum cooking power of the gas stove module.

[0171] S5063: When the temperature data is greater than the second temperature threshold and less than the third temperature threshold, determine the target cooking power to be the fifth cooking power.

[0172] The third temperature threshold is greater than the second temperature threshold, but less than the tolerance temperature of the target cookware. The fifth cooking power is less than the maximum cooking power of the gas stove module.

[0173] In one embodiment, when the cooking power determination module determines that the temperature data is greater than the second temperature threshold and less than the third temperature threshold, it indicates that the temperature inside the target cookware has increased and the cooking power needs to be reduced, and the target cooking power is determined to be the fifth cooking power.

[0174] S5064: When the temperature data is greater than or equal to the third temperature threshold, determine the target cooking power to be a sixth cooking power.

[0175] Among them, the sixth cooking fire power is smaller than the fifth cooking fire power.

[0176] In one embodiment, when the cooking power determination module determines that the temperature data is greater than or equal to the third temperature threshold, it indicates that the temperature inside the target cookware has increased significantly and the cooking power needs to be further reduced, and the target cooking power is determined to be the sixth cooking power.

[0177] When the target cooking stage is the hot pot stage, the cooking power determination module determines the magnitude relationship between the temperature data and the second temperature threshold; wherein the second temperature threshold is determined based on the temperature of the target pot when it is in a dry state; when the temperature data is less than or equal to the second temperature threshold, the target cooking power is determined to be the maximum cooking power of the gas stove module; when the temperature data is greater than the second temperature threshold and less than the third temperature threshold, the target cooking power is determined to be the fifth cooking power; wherein the third temperature threshold is greater than the second temperature threshold, and the fifth cooking power is less than the maximum cooking power of the gas stove module; when the temperature data is greater than or equal to the third temperature threshold, the target cooking power is determined to be the sixth cooking power; wherein the sixth cooking power is less than the fifth cooking power. The beneficial effects are:

[0178] First, when the temperature data of the target pot is low, the cooking power is switched to the maximum to ensure the heating rate of the target pot; when the target pot heats up, the cooking power is reduced to the fifth cooking power to reduce the heating rate in the target pot and prevent the temperature from rising too quickly; when the target pot continues to heat up, the cooking power is further reduced to the sixth cooking power to keep the cooking power within an appropriate temperature range, simplifying the manual operation steps and enhancing the user experience of the target user.

[0179] Secondly, continuously cooking at maximum power can cause local overheating at the bottom of the target pot, accelerating metal fatigue. Dynamically lowering the power can reduce thermal stress and extend the service life of the target pot and gas stove module.

[0180] Optionally, the method further includes:

[0181] A. Determine the ingredient feature data of the second ingredient according to the image data through the cooking fire power determination module.

[0182] The food characteristic data includes at least one of food volume, food quantity and food color.

[0183] In one embodiment, the cooking power determination module uses a preset image recognition algorithm to identify at least one of the volume, quantity and color of the second ingredient based on the image data.

[0184] B. Determine whether the second ingredient is fried according to the ingredient characteristic data through the cooking power determination module, and if it is determined that the second ingredient is fried, determine the target cooking power to be zero.

[0185] In one embodiment, the cooking power determination module compares the volume of the food with the standard food volume. If the volume of the food meets the standard food volume, it is determined that the second food is fully fried.

[0186] In another embodiment, the cooking fire power determination module compares the quantity of ingredients with the standard quantity of ingredients. If the quantity of ingredients meets the standard quantity of ingredients, it is determined that the second ingredient is fried.

[0187] In another embodiment, the cooking fire power determination module compares the color of the ingredient with the color of the standard ingredient. If the color of the ingredient meets the standard ingredient color, it is determined that the second ingredient is fried.

[0188] In another embodiment, the cooking fire power determination module compares the color of the ingredient with the standard ingredient color, the quantity of the ingredient with the standard ingredient quantity, and the color of the ingredient with the standard ingredient color. If the volume of the ingredient meets the standard ingredient volume, the quantity of the ingredient meets the standard ingredient quantity, and the color of the ingredient meets the standard ingredient color, it is determined that the second ingredient is fried.

[0189] Furthermore, when it is determined that the second ingredient has been fried, the target cooking firepower is determined to be zero.

[0190] The cooking power determination module determines the food characteristic data of the second food according to the image data; the cooking power determination module determines whether the second food is fried according to the food characteristic data, and if it is determined that the second food is fried, determines the target cooking power to be zero. The beneficial effects are:

[0191] Firstly, the firepower is automatically controlled to zero based on the characteristic data of the ingredients, avoiding over-frying of the ingredients and ensuring the fried taste of the second ingredient.

[0192] Secondly, automatically controlling the fire power to zero can prevent the oil temperature from exceeding the smoke point and causing fire hazards, thereby improving cooking safety.

[0193] Example 6

[0194] Figure 6 This is a flowchart of a method for determining cooking power according to the sixth embodiment of the present invention. This embodiment further optimizes and expands the step of "determining the target cooking power according to the target cooking stage" in the above embodiment, and can be combined with the above optional implementations. Figure 6 As shown, the method includes:

[0195] S601: When the target cooking mode is the frying mode, determine, through the information interaction module, a target frying oil temperature matching a second ingredient type of a second ingredient according to an ingredient type input operation performed by a target user.

[0196] In one embodiment, a target user inputs an ingredient type into the information interaction module based on their frying requirements. In response to the ingredient type input, the information interaction module determines the second ingredient type of the second ingredient and, based on a pre-configured association between ingredient types and recommended frying oil temperatures, sets the recommended frying oil temperature that matches the second ingredient type as the target frying oil temperature.

[0197] S602: When the target cooking stage is the hot oil stage, determine the magnitude relationship between the temperature data and a fourth temperature threshold value through a cooking power determination module.

[0198] The fourth temperature threshold is determined according to the target frying oil temperature, specifically, according to the difference between the target frying oil temperature and the first temperature data, such as the target frying oil temperature minus 10° C., as the fourth temperature threshold.

[0199] In one embodiment, when the target cooking stage is the hot oil stage, the target frying oil temperature is transmitted to the cooking power determination module via the information exchange module. The cooking power determination module then determines a fourth temperature threshold based on the target frying oil temperature. Furthermore, the cooking power determination module compares the temperature data with the fourth temperature threshold to determine a magnitude relationship between the temperature data and the fourth temperature threshold.

[0200] S603: When the temperature data is greater than or equal to the fourth temperature threshold, determine the target cooking power to be the eighth cooking power.

[0201] S604: When the temperature data is less than the fourth temperature threshold and greater than the fifth temperature threshold, determine the target cooking power to be the seventh cooking power.

[0202] Among them, the fifth temperature threshold is lower than the fourth temperature threshold, and the seventh cooking fire power is higher than the eighth cooking fire power.

[0203] In one embodiment, when the cooking fire power determination module determines that the temperature data is greater than or equal to the fourth temperature threshold, the target cooking fire power is determined to be the eighth cooking fire power; when the cooking fire power determination module determines that the temperature data is less than the fourth temperature threshold and greater than the fifth temperature threshold, the target cooking fire power is determined to be the seventh cooking fire power.

[0204] Optionally, the eighth cooking firepower range is set to be within 0.2 to 0.5 kW.

[0205] S605: When the temperature data is less than or equal to a fifth temperature threshold, determine the target cooking power to be the maximum cooking power of the gas stove module.

[0206] In one embodiment, when the temperature data determined by the cooking power is less than or equal to the fifth temperature threshold, the target cooking power is determined to be the maximum cooking power of the gas stove module.

[0207] When the target cooking stage is the hot oil stage, the cooking power determination module determines the magnitude relationship between the temperature data and the fourth temperature threshold; wherein the fourth temperature threshold is determined according to the target frying oil temperature; when the temperature data is greater than or equal to the fourth temperature threshold, the target cooking power is determined to be the eighth cooking power; when the temperature data is less than the fourth temperature threshold and greater than the fifth temperature threshold, the target cooking power is determined to be the seventh cooking power; wherein the fifth temperature threshold is less than the fourth temperature threshold, and the seventh cooking power is greater than the eighth cooking power; and when the temperature data is less than or equal to the fifth temperature threshold, the target cooking power is determined to be the maximum cooking power of the gas stove module. The beneficial effects are:

[0208] Firstly, by automatically adjusting the cooking firepower, the oil temperature can be maintained near the recommended target frying oil temperature, thereby ensuring the fried taste of the second ingredient and avoiding the problem of under-frying or burnt frying.

[0209] Secondly, the target user only needs to put in the ingredients, and the gas stove control system can automatically control the cooking fire power without the target user having to manually set it, which simplifies the manual operation steps and enhances the user experience of the target user.

[0210] Example 7

[0211] Figure 7 This is a flowchart of a method for determining cooking power provided by Example 7 of the present invention. This embodiment further optimizes and expands the step of "determining the target cooking power according to the target cooking stage" in the above embodiment, and can be combined with the above optional implementations. Figure 7 As shown, the method includes:

[0212] S701: When the target cooking stage is the frying stage, determine, by a cooking power determination module, whether the temperature rise rate data is less than a second temperature rise rate threshold.

[0213] The frying phase consists of an oil temperature rise phase and an oil temperature maintenance phase. The oil temperature rise phase occurs when the oil temperature drops sharply after the user adds the second ingredient. The oil temperature maintenance phase occurs when the second ingredient reaches the recommended target frying oil temperature.

[0214] The second heating rate threshold can be set and adjusted according to actual business needs.

[0215] In one embodiment, when the target cooking stage is the frying stage, the cooking power determination module compares the heating rate data with the second heating rate threshold to determine whether the heating rate data is less than the second heating rate threshold.

[0216] S702: When it is determined that the temperature rise rate data is less than a second temperature rise rate threshold, the target cooking stage is determined to be the oil temperature rise sub-stage, and the target cooking power is determined to be a ninth cooking power.

[0217] Among them, the ninth cooking fire power is greater than or equal to the seventh cooking fire power.

[0218] In one embodiment, when it is determined that the heating rate data is less than the second heating rate threshold, it indicates that the target user has just put the second ingredient into the target pot and the oil temperature has dropped steeply, then the target cooking stage is determined to be the oil temperature heating sub-stage, and the target cooking firepower is further determined to be the ninth cooking firepower.

[0219] When the target cooking stage is the frying stage, the cooking power determination module determines whether the heating rate data is less than a second heating rate threshold value; when it is determined that the heating rate data is less than the second heating rate threshold value, the target cooking stage is determined to be the oil temperature heating sub-stage, and the target cooking power is determined to be a ninth cooking power; wherein the ninth cooking power is greater than or equal to the seventh cooking power. On the one hand, using the heating rate data to determine the oil temperature heating sub-stage can ensure the accuracy and simulation of the oil temperature heating sub-stage determination; on the other hand, when it is determined that the target cooking stage is the oil temperature heating sub-stage, adjusting the cooking power to the larger ninth cooking power can enable the second food to quickly reach a suitable frying oil temperature, that is, the target frying oil temperature.

[0220] S703. When it is determined that the heating rate data is greater than or equal to the second heating rate threshold, the cooking fire power determination module determines whether the temperature data is greater than or equal to the fourth temperature threshold, and when the temperature data is greater than or equal to the fourth temperature threshold, determines that the target cooking stage is the oil temperature maintenance sub-stage.

[0221] In one embodiment, when it is determined that the heating rate data is greater than or equal to the second heating rate threshold, the temperature data is numerically compared with the fourth temperature threshold through the cooking fire power determination module. If it is determined that the temperature data is greater than or equal to the fourth temperature threshold, it indicates that the temperature is rising slowly and the oil temperature is approaching the recommended target frying oil temperature. Then, the target cooking stage is determined to be the oil temperature maintenance sub-stage.

[0222] By determining that the heating rate data is greater than or equal to the second heating rate threshold, the cooking fire power determination module determines whether the temperature data is greater than or equal to the fourth temperature threshold, and when the temperature data is greater than or equal to the fourth temperature threshold, the target cooking stage is determined to be the oil temperature maintenance sub-stage. Since the oil temperature maintenance sub-stage is judged by jointly using the two parameter dimensions of heating rate data and temperature data, the accuracy, simulation and reliability of the judgment of the oil temperature maintenance sub-stage can be guaranteed.

[0223] S704: When the target cooking stage is the oil temperature maintenance sub-stage, determine, by the cooking power determination module, whether the temperature data in the second time period is less than a fourth temperature threshold.

[0224] The second time period can be set and adjusted according to actual business needs, such as setting the second time period to within 1 to 10 seconds.

[0225] S705. When it is determined that the temperature data in the second time period is greater than or equal to the fourth temperature threshold, determine the target cooking power to be the twelfth cooking power; when it is determined that the temperature data in the second time period is less than the fourth temperature threshold and greater than or equal to the sixth temperature threshold, determine the target cooking power to be the eleventh cooking power.

[0226] S706: When it is determined that the temperature data in the second time period is less than the sixth temperature threshold, determine the target cooking power to be the tenth cooking power.

[0227] The sixth temperature threshold is smaller than the fourth temperature threshold and is determined based on the difference between the fourth temperature threshold and the second temperature data, and the second temperature data can be optionally set within 3 to 8°C.

[0228] The tenth cooking power is greater than the eleventh cooking power, the eleventh cooking power is greater than the twelfth cooking power, the twelfth cooking power is less than or equal to the eighth cooking power, and the eleventh cooking power is less than or equal to the seventh cooking power.

[0229] In one embodiment, when the target cooking stage is the oil temperature maintenance sub-stage, the cooking power determination module determines whether the temperature data in the second time period is less than a fourth temperature threshold.

[0230] When it is determined that the temperature data in the second time period is greater than or equal to the fourth temperature threshold, it indicates that the oil temperature has reached the recommended target frying oil temperature (the fourth temperature threshold), and therefore the target cooking power is determined to be the smaller twelfth cooking power.

[0231] When it is determined that the temperature data in the second time period is less than the fourth temperature threshold and greater than or equal to the sixth temperature threshold, it indicates that the oil temperature has gradually fallen below the target frying oil temperature (the fourth temperature threshold), and therefore the target cooking power is determined to be the larger eleventh cooking power.

[0232] When it is determined that the temperature data in the second time period is less than the sixth temperature threshold, it indicates that the oil temperature is far lower than the target frying oil temperature (the fourth temperature threshold), so the target cooking power is determined to be the larger tenth cooking power.

[0233] When the target cooking stage is the oil temperature maintenance sub-stage, the cooking power determination module determines whether the temperature data in the second time period is less than the fourth temperature threshold; if it is determined that the temperature data in the second time period is greater than or equal to the fourth temperature threshold, the target cooking power is determined to be the twelfth cooking power; if it is determined that the temperature data in the second time period is less than the fourth temperature threshold and greater than or equal to the sixth temperature threshold, the target cooking power is determined to be the eleventh cooking power; and if it is determined that the temperature data in the second time period is less than the sixth temperature threshold, the target cooking power is determined to be the tenth cooking power. Advantageous effects are:

[0234] Firstly, it enables the automatic control of the cooking firepower during the oil temperature maintenance sub-stage, ensuring that the oil temperature is always close to the target frying oil temperature, further ensuring the fried taste of the second ingredient.

[0235] Secondly, due to the introduction of the continuous detection mechanism in the second time period, it is possible to avoid the collected temperature data being the temperature of the food surface, which would cause instantaneous changes in the temperature data and affect the control of cooking fire power, thereby ensuring the accuracy and reliability of cooking fire power control.

[0236] Example 8

[0237] Figure 8 This is a flow chart of a method for controlling the firepower of a gas stove provided by the eighth embodiment of the present invention. This embodiment further optimizes and expands the above embodiment and can be combined with the above optional implementations. Figure 8 As shown, the method includes:

[0238] S801. Determine a target cooking mode according to the cooking mode selection implemented by the target user through an information interaction module, and determine candidate cooking stages included in the target cooking mode according to the target cooking mode.

[0239] S802: Acquire target characteristic data of the target cookware during the cooking process through a data acquisition module.

[0240] The target characteristic data includes temperature data, heating rate data and / or image data.

[0241] S803: When the target cooking mode is the stir-fry mode, determine the magnitude relationship between the temperature data and a seventh temperature threshold value through a cooking power determination module.

[0242] S804: When the temperature data is greater than or equal to a seventh temperature threshold, determine that the target cooking stage is the sautéing stage.

[0243] The seventh temperature threshold can be set and adjusted according to actual business needs, such as setting the seventh temperature threshold to 80-100°C.

[0244] In one embodiment, the cooking power determination module compares the temperature data with the seventh temperature threshold, and when the temperature data is greater than or equal to the seventh temperature threshold, the target cooking stage is determined to be the sautéing stage.

[0245] S805: When the temperature data is less than the seventh temperature threshold, the cooking power determination module determines the magnitude relationship between the temperature rise rate data and the third temperature rise rate threshold.

[0246] The third heating rate threshold can be set and adjusted according to actual business needs, such as setting the third heating rate threshold to 130-170°C / 10s.

[0247] In one embodiment, when the temperature data is less than the seventh temperature threshold, the cooking fire power determination module further performs a numerical comparison between the heating rate data and the third heating rate threshold to determine the size relationship between the heating rate data and the third heating rate threshold.

[0248] S806: When the temperature rise rate data is greater than or equal to the third temperature rise rate threshold, determine that the target cooking stage is the heating stage; when the temperature rise rate data is less than the third temperature rise rate threshold, determine that the target cooking stage is the stir-frying stage.

[0249] In one embodiment, when the heating rate data is greater than or equal to the third heating rate threshold, it indicates that the temperature inside the target cookware is heating faster, and the target cooking stage is determined to be the heating stage, such as the hot pot stage or the hot oil stage; when the heating rate data is less than the third heating rate threshold, it indicates that the temperature inside the target cookware is heating slower, and the target cooking stage is determined to be the frying stage.

[0250] When the target cooking mode is the stir-fry mode, the cooking power determination module determines the magnitude relationship between the temperature data and the seventh temperature threshold; when the temperature data is greater than or equal to the seventh temperature threshold, the target cooking stage is determined to be the sautéing stage; when the temperature data is less than the seventh temperature threshold, the cooking power determination module determines the magnitude relationship between the heating rate data and the third heating rate threshold; when the heating rate data is greater than or equal to the third heating rate threshold, the target cooking stage is determined to be the heating stage; when the heating rate data is less than the third heating rate threshold, the target cooking stage is determined to be the stir-frying stage. The beneficial effects are:

[0251] Firstly, it realizes the effect of automatic identification of cooking stages and improves the intelligence level of the cooking process.

[0252] Secondly, there is no need for manual settings by the target user, which simplifies the manual operation steps and enhances the user experience of the target user.

[0253] S807: Determine a target cooking power according to the target cooking stage, and heat the target pot with the target cooking power through the gas stove module.

[0254] Optionally, a target cooking power is determined according to a target cooking stage, including:

[0255] A1. When the target cooking stage is the heating stage, the target cooking power is determined to be the maximum cooking power of the gas stove module.

[0256] In one embodiment, when the target cooking stage is the heating stage, it indicates that a high fire is required at this time, and thus the target cooking power is determined to be the maximum cooking power of the gas stove module.

[0257] B1. When the target cooking stage is the sautéing stage, determine the target cooking heat to be the thirteenth cooking heat.

[0258] Among them, the thirteenth cooking fire power is less than the maximum cooking fire power of the gas stove module.

[0259] In one embodiment, when the target cooking stage is the sautéing stage, it indicates that the cooking heat needs to be reduced to prevent the ingredients from burning, and thus the target cooking heat is determined to be the thirteenth smaller cooking heat.

[0260] By determining the target cooking power to be the maximum cooking power of the gas stove module when the target cooking stage is the heating stage, and determining the target cooking power to be the thirteenth cooking power when the target cooking stage is the sautéing stage; wherein the thirteenth cooking power is less than the maximum cooking power of the gas stove module, the beneficial effects are:

[0261] First, use maximum cooking power during the heating stage to shorten the initial heating time of the pan oil.

[0262] Secondly, use a smaller cooking fire during the sautéing stage to avoid burning of ingredients, reduce the generation of harmful substances, and improve the safety of food.

[0263] Optionally, a target cooking power is determined according to a target cooking stage, including:

[0264] A2. When the target cooking stage is the stir-frying stage, the cooking power determination module determines the third ingredient type of the third ingredient in the target cookware according to the image data.

[0265] Here, the third ingredient type refers to the ingredient type corresponding to the third ingredient, and does not specifically refer to a certain ingredient type.

[0266] In one embodiment, the data acquisition module collects image data of the target cookware during the cooking process and transmits the image data to the cooking power determination module. The cooking power determination module uses a preset image recognition method to identify the type of the third ingredient based on the image data and determine the third ingredient type.

[0267] B2. When it is determined that the third ingredient type is vegetables, the target cooking power is determined to be the fourteenth cooking power.

[0268] C2. When the third ingredient type is determined to be meat, the target cooking power is determined to be the fifteenth cooking power.

[0269] Among them, the fourteenth cooking fire power is smaller than the fifteenth cooking fire power.

[0270] In one embodiment, because vegetables are rich in heat-sensitive ingredients such as vitamin C and phytochemicals, and stir-frying generally involves large quantities of vegetables, excessive cooking power can easily burn the surface of the vegetables that come into contact with the target cookware, resulting in significant nutrient loss. Therefore, if the third ingredient type is determined to be vegetables, the target cooking power is determined to be a lower fourteenth cooking power level.

[0271] Since stir-frying meat generally involves a small amount of food, and meat is rich in protein, which denatures rapidly at high temperatures, locking in moisture and making the meat more tender. Therefore, if the third ingredient type is determined to be meat, the target cooking power is set to the higher cooking power of 15th.

[0272] When the target cooking stage is the stir-fry stage, the cooking fire power determination module determines the third ingredient type of the third ingredient in the target pot according to the image data; when it is determined that the third ingredient type is vegetables, the target cooking fire power is determined to be the fourteenth cooking fire power; when it is determined that the third ingredient type is meat, the target cooking fire power is determined to be the fifteenth cooking fire power; wherein the fourteenth cooking fire power is less than the fifteenth cooking fire power, thereby achieving the effect of using different sizes of cooking fire power according to different ingredient types, making the cooking process more targeted and ensuring the stir-fried taste of the ingredients.

[0273] Optionally, a target cooking power is determined according to a target cooking stage, including:

[0274] A3. When the target cooking stage is the stir-frying stage, the cooking power determination module determines the shape of the third ingredient according to the image data.

[0275] In one embodiment, the data acquisition module collects image data of the target cookware during the cooking process and transmits the image data to the cooking power determination module. The cooking power determination module uses a preset image recognition method to identify the shape of the third ingredient based on the image data to determine the shape of the third ingredient.

[0276] B3. When the shape of the food is determined to be the first shape, the target cooking power is determined to be the sixteenth cooking power.

[0277] Among them, the first shape includes filament shape and diced shape.

[0278] C3. When it is determined that the shape of the food is the second shape, the target cooking power is determined to be the seventeenth cooking power.

[0279] Among them, the second shape includes sheet and block, and the cooking power of sixteen is greater than the cooking power of seventeen.

[0280] In one embodiment, since the first shape (shredded and diced) of the food is smaller in volume, heat can be transferred to the interior of the third food faster to achieve maturity. Therefore, when the shape of the food is determined to be the first shape, the target cooking power can be selected as the larger sixteenth cooking power.

[0281] Since the second shape (slice and block) of ingredients is larger in volume, if a higher cooking power is selected at this time, the temperature in the pot will quickly reach a high temperature, and the surface temperature of the third ingredient will be high and cooked, but the interior will not be cooked due to its large volume and slow heat conduction, which may easily lead to the problem of the inside being uncooked and the outside being burnt. Therefore, when it is determined that the shape of the ingredient is the second shape, the target cooking power is selected as the smaller seventeenth cooking power.

[0282] When the target cooking stage is the stir-fry stage, the cooking firepower determination module determines the shape of the third ingredient according to the image data. When the shape of the ingredient is determined to be the first shape, the target cooking firepower is determined to be the sixteenth cooking firepower. When the shape of the ingredient is determined to be the second shape, the target cooking firepower is determined to be the seventeenth cooking firepower. Among them, the sixteenth cooking firepower is greater than the seventeenth cooking firepower, which achieves the effect of using different sizes of cooking firepower according to different shapes of ingredients, making the cooking process more targeted and ensuring the stir-fried taste of the ingredients.

[0283] Optionally, the method further includes:

[0284] A4. Determine the magnitude relationship between the temperature data and the eighth temperature threshold value through the cooking power determination module.

[0285] The eighth temperature threshold is determined according to the ripening temperature of the third ingredient in the target cookware. Preferably, the ripening temperature of the third ingredient is set as the eighth temperature threshold.

[0286] In one embodiment, the cooking power determination module performs a numerical comparison between the temperature data and the eighth temperature threshold to determine the magnitude relationship between the temperature data and the eighth temperature threshold.

[0287] B4. When it is determined that the temperature data is less than the eighth temperature threshold, the target cooking power is determined to be the eighteenth cooking power; when it is determined that the temperature data is greater than or equal to the eighth temperature threshold, the target cooking power is determined to be the nineteenth cooking power.

[0288] Among them, the eighteenth cooking fire power is greater than the nineteenth cooking fire power.

[0289] In one embodiment, when it is determined that the temperature data is less than the eighth temperature threshold, it indicates that the third ingredient is not yet mature, and therefore the target cooking power is selected to be the larger eighteenth cooking power; when it is determined that the temperature data is greater than or equal to the eighth temperature threshold, it indicates that the third ingredient is close to being mature, and therefore the target cooking power is selected to be the smaller nineteenth cooking power.

[0290] The cooking power determination module determines the magnitude relationship between the temperature data and the eighth temperature threshold. If the temperature data is less than the eighth temperature threshold, the target cooking power is determined to be the eighteenth cooking power. If the temperature data is greater than or equal to the eighth temperature threshold, the target cooking power is determined to be the nineteenth cooking power. The beneficial effect is:

[0291] When the temperature data is less than the eighth temperature threshold, it indicates that the third ingredient is not yet mature. At this time, selecting the target cooking power as the larger eighteenth cooking power can help to quickly mature the third ingredient; when the temperature data is greater than or equal to the eighth temperature threshold, it indicates that the third ingredient is approaching maturity. If a high cooking power is continued at this time, water loss will be accelerated, resulting in nutrient loss; and the target user starts to season and cook, and the added salt and soy sauce will be more likely to produce harmful substances under high cooking power. At this time, by reducing the cooking power to the nineteenth cooking power, the user can better cook and make delicious food with good color, fragrance and taste.
