[0028] See also Figure 1 , Figure 1 This is a flow chart of an intelligent control method for an intelligent cooking system provided in one embodiment of the present invention. An embodiment of the present invention provides an intelligent control method for an intelligent cooking system, which is applied to an intelligent cooking system, and the intelligent cooking system includes a range hood and a gas stove. Both the range hood and the gas stove are equipped with a central processing unit or a microprocessor, and are also provided with a wireless communication module (such as a Wi-Fi module, a 5G communication module and a low-power Bluetooth module). The intelligent control method for the intelligent cooking system provided in this embodiment of the present invention includes steps S101 to S106.

[0029] S101, the gas stove is started to an on state, and the range hood is controlled to start to an on state.

[0030] In this embodiment, the technical solution is described with the intelligent cooking system as the execution subject. When the user needs to cook, the user turns on the gas stove, so that the gas stove starts to turn on, and controls the range hood to start to turn on at the same time. The gas stove and the range hood are set to a linkage mode. The power-on signal triggered when the gas stove is turned on can also trigger the range hood to start at the same time, which is convenient for users.

[0031] S102: The gas stove obtains the weight of the food to be processed and the type of cooking process.

[0032] In this embodiment, before starting cooking, the user needs to place the food to be processed on the weighing area set on the gas stove, and the gas stove obtains the food weight of the food to be processed. Among them, the food to be processed mainly includes the main ingredients of the recipe, and the user places the main ingredients one by one on the weighing area set on the gas stove. Then, the user also needs to select the required cooking process type, which includes stir-frying, burning, frying, deep-frying, frying, stewing, braising, simmering, gratin, boiling, stewing, cooking, etc., wherein a button for the user to select the cooking process type can be set on the gas stove, and the gas stove obtains the corresponding cooking process type through the button selected by the user. A voice device can also be set on the gas stove, and the voice device receives the user's voice command, so that the gas stove can receive the cooking process type directly spoken by the user. For example, taking chicken soup as an example, the user sets a chicken on the weighing area, and the gas stove obtains the weight of the chicken (such as 2000 grams), and then obtains the cooking process type selected by the user as stewing. In addition, the gas stove also needs to send the obtained food weight and cooking process type of the food to be processed to the range hood through the wireless communication module.

[0033] In one embodiment, step S102 includes:

[0034] The gas stove obtains the weight of the food to be processed through a weighing device, and detects the cooking process type input based on a cooking process selection key.

[0035] In this embodiment, in order to obtain the weight of the food to be processed, a weighing device is provided on the gas stove. Preferably, the weighing device is an electronic scale. The user places the food to be processed on the weighing device before cooking, and the gas stove obtains the weight of the food to be processed. A cooking process selection key is also provided on the gas stove. When the user selects the desired cooking process selection key, the gas stove can detect the cooking process type input based on the cooking process selection key.

[0036] S103: The range hood obtains the food type of the food to be processed through image recognition.

[0037] In this embodiment, the range hood obtains the food type (such as pork, chicken, mutton, cabbage, cucumber, etc.) of the food to be processed through image recognition. When the user places the food to be processed on the weighing area set on the gas stove, the gas stove obtains the food weight of the food to be processed, and the range hood obtains the image of the food to be processed, so that the food type of the current food to be processed can be further obtained based on image recognition. In addition, the user can also place the food to be processed in the designated area and arrange it neatly, and the range hood obtains the image of the food to be processed and further obtains the food type of the current food to be processed.

[0038] In one embodiment, step S103 includes:

[0039] The range hood acquires a food image corresponding to the food to be processed through an image recognition device;

[0040] The range hood obtains the recognition result of the food image through a pre-stored target detection model;

[0041] The food type of the food to be processed is determined according to the recognition result.

[0042] In this embodiment, an image recognition device is provided on the range hood. Preferably, the image recognition device can be a camera, and the camera can collect food images of the food to be processed. And the target detection model (such as YoLoV3, YoLoV5, etc.) is pre-stored in the range hood as an image recognition model to obtain the recognition result of the food image. For example, after obtaining the food included in the food image and the prediction frame corresponding to the food through the YoLoV5 model, the upper left corner coordinates of the prediction frame corresponding to the food, the length and width values ​​of the prediction frame, the classification category to which the prediction frame belongs (such as chicken, etc.), and the confidence of the classification category to which the food corresponding to the prediction frame belongs are all known. Based on the classification category to which the prediction frame belongs and the confidence of the classification category to which the food corresponding to the prediction frame belongs (for example, if the confidence is greater than or equal to 80%, it means that the classification category to which the prediction frame belongs is credible), the food type of the food to be processed is determined. For example, after the range hood collects the food image corresponding to the food to be processed through the camera, the food in the food image and the color, shape and state of the food are obtained through the target detection model, and then the food type of the food is determined.

[0043] S104: The range hood forms cooking input parameters according to the food weight, the cooking process type and the food type, obtains target cooking data matching the cooking input parameters in a local storage repository and sends the target cooking data to the gas stove.

[0044] In this embodiment, the range hood receives the information of the food weight and cooking process type of the food to be processed sent by the gas stove through the wireless communication module, and the range hood forms the cooking input parameters according to the food weight, cooking process type and food type, so as to obtain the target cooking data matching the cooking input parameters in the local storage, wherein the target cooking data includes the odor type, odor concentration, cooking temperature curve and fire control data matching the cooking input parameters, and the cooking temperature is the temperature corresponding to the cooking fire. Then, the range hood sends the acquired target cooking data to the gas stove for cooking.

[0045] S105: The gas stove controls the cooking fire power according to the target cooking data.

[0046] In this embodiment, the gas stove is provided with a fire power start device, a fire power control device and a fire power shut-off device to control the cooking fire power during the cooking process, wherein the fire power start device is used to turn on the fire power on the gas stove and control the range hood to automatically turn on; the fire power control device controls the size of the fire power in real time through the received signal; the fire power shut-off device automatically shuts off the fire power through the received signal, and can also shut off the fire power manually. After the gas stove receives the target cooking data sent by the range hood, the fire power start device is started to the on state, and the user can start cooking. During the cooking process, the fire power control device in the gas stove controls the cooking fire power size according to the target cooking data, thereby automatically adjusting the fire power size during the cooking process, making it convenient for the user to cook.

[0047] S106: If the gas stove determines that the current cumulative cooking time is greater than or equal to the target cooking time corresponding to the target cooking data, the gas stove and the range hood are both switched to an off state.

[0048] In this embodiment, when the user is cooking, when the fire starting device is started to the on state, the gas stove starts to record the cumulative cooking time from this moment. If the gas stove determines that the current cumulative cooking time is greater than or equal to the target cooking time corresponding to the target cooking data, it means that the cooking is completed. The fire shutoff device of the gas stove is started to the off state, the gas stove is switched to the off state, and the range hood is also switched to the off state, and the user ends cooking.

[0049] In one embodiment, after step S105 and before step S106, the following steps are included:

[0050] S105a, the range hood acquires current cooking parameters; the current cooking parameters include current odor type, current odor concentration and current cooking temperature;

[0051] S105b, if it is determined that the current odor concentration exceeds the preset first odor concentration threshold, obtaining a first detection time, reducing the current cooking temperature by a preset temperature adjustment value to obtain a first adjusted cooking temperature value, and maintaining the firepower corresponding to the first adjusted cooking temperature value within a preset first time period;

[0052] S105c, if it is determined that the current cumulative cooking time is equal to the sum of the first detection time and the preset first duration, obtaining a first standard cooking temperature corresponding to the current cumulative cooking time in the target cooking data;

[0053] S105d: The gas stove controls the cooking fire power according to the first standard cooking temperature.

[0054] In this embodiment, see Figure 2 The range hood is provided with an infrared temperature sensor and an odor detection device. The infrared temperature sensor is used to obtain the cooking temperature during the cooking process, and the odor detection device is used to obtain the odor type and odor concentration during the cooking process. When the user is cooking, the food will undergo a chemical reaction to form volatile compounds. The range hood obtains the current odor type, current odor concentration and current cooking temperature. The current odor type and current odor concentration can be used to judge the current cooking state of the food, such as whether the current food cooking state is good, the food cooking state is poor, or the food cooking state is burnt.

[0055] The range hood obtains the corresponding preset first odor concentration threshold value according to the current odor type, and determines the magnitude relationship between the current odor concentration and the preset first odor concentration threshold value. If the range hood determines that the current odor concentration exceeds the preset first odor concentration threshold value, it means that the current firepower is too large and the food is about to burn. In order to prevent the firepower from continuing to be too large to make the food burn, the range hood obtains the first detection time, and starts recording the cumulative cooking time when the firepower starting device is started to the on state. The corresponding cumulative cooking time when the range hood determines that the current odor concentration exceeds the preset first odor concentration threshold value is the first detection time. Then, the range hood reduces the current cooking temperature by the preset temperature adjustment value to obtain the first adjusted cooking temperature value. For example, if the preset temperature adjustment value is 10°C, the current cooking temperature is reduced by 10°C to obtain the first adjusted cooking temperature value. The firepower control device controls the firepower size according to the first adjusted cooking temperature value, and the gas stove maintains the firepower size corresponding to the first adjusted cooking temperature value within the preset first time length. The preset first time length can be set to 3min, 5min, etc., so as to reduce the cooking firepower and avoid excessive firepower. Finally, if the range hood determines that the current cumulative cooking time is equal to the sum of the first detection time and the preset first duration, it obtains the first standard cooking temperature corresponding to the current cumulative cooking time in the target cooking data and sends the first standard cooking temperature to the gas stove.

[0056] When the gas stove receives the first standard cooking temperature sent by the range hood, it controls the cooking fire power according to the first standard cooking temperature, so that during the cooking process from the current cumulative cooking time to the end of cooking, the gas stove can continue to control the cooking fire power according to the target cooking data, thereby completing the cooking.

[0057] In one embodiment, after step S105a, the process further includes:

[0058] S105e, if it is determined that the current odor concentration does not exceed the preset second odor concentration threshold, obtaining a second detection time, increasing the current cooking temperature by a preset temperature adjustment value to obtain a second adjusted cooking temperature value, and maintaining the firepower corresponding to the second adjusted cooking temperature value within a preset second time period;

[0059] S105f, if it is determined that the current cumulative cooking time is equal to the sum of the second detection time and the preset second duration, obtaining a second standard cooking temperature corresponding to the current cumulative cooking time in the target cooking data;

[0060] S105g: The gas stove controls the cooking fire power according to the second standard cooking temperature.

[0061] In this embodiment, see Figure 3 The range hood obtains the corresponding preset second odor concentration threshold value according to the current odor type, and determines the magnitude relationship between the current odor concentration and the preset second odor concentration threshold value. If the range hood determines that the current odor concentration does not exceed the preset second odor concentration threshold value, it means that the current firepower is too small, and the food has not reached the food cooking state corresponding to the current cooking cumulative time, such as the food is not cooked. The range hood obtains the second detection time, and starts recording the cooking cumulative time when the firepower starting device is started to the on state. The corresponding cooking cumulative time when the range hood determines that the current odor concentration does not exceed the preset second odor concentration threshold value is the second detection time. Then, the range hood increases the current cooking temperature by the preset temperature adjustment value to obtain the second adjusted cooking temperature value, and the firepower control device controls the firepower size according to the second adjusted cooking temperature value, and the gas stove maintains the firepower size corresponding to the second adjusted cooking temperature value within the preset second time length, and the preset second time length can be set to 3min, 5min, etc., so as to increase the cooking firepower so that the food reaches the standard food cooking state. Finally, if the range hood determines that the current cumulative cooking time is equal to the sum of the second detection time and the preset second time length, it obtains the second standard cooking temperature corresponding to the current cumulative cooking time in the target cooking data and sends the second standard cooking temperature to the gas stove.

[0062] When the gas stove receives the second standard cooking temperature sent by the range hood, the cooking firepower is controlled accordingly according to the second standard cooking temperature, so that during the cooking process corresponding to the current cooking cumulative time to the end of cooking, the gas stove can continue to control the cooking firepower according to the target cooking data, thereby completing cooking. Thus, through the two-way linkage between the gas stove and the range hood, the odor type, odor concentration and cooking temperature during the cooking process are monitored and analyzed, thereby matching the optimal parameters for food cooking, automatically adjusting the firepower during the cooking process in real time, and ensuring that the food cooking effect reaches a stable and good state.

[0063] In one embodiment, after step S105 and before step S106, the method further includes:

[0064] The range hood collects and saves cooking pictures through an image recognition device according to a preset picture collection cycle.

[0065] In this embodiment, when the user is cooking and the food is not covered during the cooking process, auxiliary monitoring can also be performed through the image recognition device in the range hood. The range hood collects the cooking pictures of the food during the cooking process through the image recognition device according to the preset picture collection cycle, and saves the cooking pictures, so as to further collect the color, shape and state of the food based on the cooking pictures, call the data in the local storage of the range hood, match the fire control data, such as switching from high fire to low fire, and the range hood sends the fire control data to the gas stove, so that the fire control device of the gas stove can automatically control the fire according to the fire control data to ensure that the food cooking effect reaches a stable and good state.

[0066] In one embodiment, after step S106, the method further includes:

[0067] If the range hood detects that the current system time meets a preset update condition, it obtains update data from the cloud server and updates the cooking data in the local storage repository according to the update data.

[0068] In this embodiment, see Figure 4 , Figure 4 The application scenario diagram of the intelligent cooking system provided in this embodiment, the intelligent cooking system includes a range hood 11 and a gas stove 12, the range hood 11 is communicatively connected to the cloud server 13, in order to update the data in time so as to update the cooking data stored in the range hood 11 in time, if the range hood 11 detects that the current system time meets the preset update conditions, the range hood 11 obtains the update data of the cloud server 13, and updates the cooking data in the local storage repository according to the update data.

[0069] The intelligent control method of the intelligent cooking system provided by the embodiment of the present invention can automatically adjust the firepower of the gas stove during cooking through the two-way linkage of the gas stove and the range hood, making the range hood cooking process more intelligent. It can also monitor and analyze the odor type, odor concentration and cooking temperature during the cooking process, thereby matching the optimal parameters for food cooking, automatically adjusting the firepower during the cooking process in real time, and ensuring that the food cooking effect reaches a stable and good state. The present invention makes the range hood cooking process more intelligent and more convenient for users to use.

[0070] An embodiment of the present invention further provides an intelligent cooking system, which is used to execute any embodiment of the intelligent control method of the intelligent cooking system described above, and the intelligent cooking system includes a range hood and a gas stove.

[0076] 15) The gas stove is also used to control the cooking fire power according to the target cooking data;

[0077] 16) The gas stove is further configured to switch both the gas stove and the range hood to an off state if it is determined that the current cumulative cooking time is greater than or equal to the target cooking time corresponding to the target cooking data.

[0078] In this embodiment, in step 11), when the user needs to cook, the user turns on the gas stove, so that the gas stove starts to turn on, and controls the range hood to start to turn on at the same time. The gas stove and the range hood are set to a linkage mode, and the power-on signal triggered when the gas stove is turned on can also trigger the range hood to start at the same time, which is convenient for users.

[0079] In step 12), before starting cooking, the user needs to place the food to be processed on the weighing area set on the gas stove, and the gas stove obtains the food weight of the food to be processed. Among them, the food to be processed mainly includes the main ingredients of the recipe, and the user places the main ingredients one by one on the weighing area set on the gas stove. Then, the user also needs to select the required cooking process type, which includes stir-frying, burning, frying, deep-frying, frying, stewing, braising, simmering, gratin, boiling, stewing, cooking, etc., wherein a button for the user to select the cooking process type can be set on the gas stove, and the gas stove obtains the corresponding cooking process type through the button selected by the user. A voice device can also be set on the gas stove, and the voice command of the user is received through the voice device, so that the gas stove can receive the cooking process type directly spoken by the user. For example, taking chicken soup as an example, the user sets a chicken on the weighing area, and the gas stove obtains the weight of the chicken (such as 2000 grams), and then obtains the cooking process type selected by the user as stewing. In addition, the gas stove needs to send the obtained food weight and cooking process type of the food to be processed to the range hood through the wireless communication module.

[0080] In one embodiment, step 12) includes:

[0081] The gas stove is also used to obtain the weight of the food to be processed through a weighing device, and detect the cooking process type input based on the cooking process selection key.

[0082] In this embodiment, in order to obtain the weight of the food to be processed, a weighing device is provided on the gas stove. Preferably, the weighing device is an electronic scale. The user places the food to be processed on the weighing device before cooking, and the gas stove obtains the weight of the food to be processed. A cooking process selection key is also provided on the gas stove. When the user selects the desired cooking process selection key, the gas stove can detect the cooking process type input based on the cooking process selection key.

[0083] In step 13), the range hood obtains the food type (such as pork, chicken, mutton, cabbage, cucumber, etc.) of the food to be processed through image recognition. When the user places the food to be processed on the weighing area set on the gas stove, the gas stove obtains the food weight of the food to be processed, and the range hood obtains the image of the food to be processed, so that the food type of the current food to be processed can be further obtained based on image recognition. In addition, the user can also place the food to be processed in the designated area and arrange it neatly, and the range hood obtains the image of the food to be processed and further obtains the food type of the current food to be processed.

[0084] In one embodiment, step 13) includes:

[0085] The range hood is further used to obtain a food image corresponding to the food to be processed through an image recognition device;

[0086] The range hood is further used to obtain a recognition result of the food image through a pre-stored target detection model;

[0087] The range hood is further used to determine the food type of the food to be processed according to the recognition result.

[0088] In this embodiment, an image recognition device is provided on the range hood. Preferably, the image recognition device can be a camera, and the camera can collect food images of the food to be processed. And the target detection model (such as YoLoV3, YoLoV5, etc.) is pre-stored in the range hood as an image recognition model to obtain the recognition result of the food image. For example, after obtaining the food included in the food image and the prediction frame corresponding to the food through the YoLoV5 model, the upper left corner coordinates of the prediction frame corresponding to the food, the length and width values ​​of the prediction frame, the classification category to which the prediction frame belongs (such as chicken, etc.), and the confidence of the classification category to which the food corresponding to the prediction frame belongs are all known. Based on the classification category to which the prediction frame belongs and the confidence of the classification category to which the food corresponding to the prediction frame belongs (for example, if the confidence is greater than or equal to 80%, it means that the classification category to which the prediction frame belongs is credible), the food type of the food to be processed is determined. For example, after the range hood collects the food image corresponding to the food to be processed through the camera, the food in the food image and the color, shape and state of the food are obtained through the target detection model, and then the food type of the food is determined.

[0089] In step 14), the range hood receives the information of the food weight and cooking process type of the food to be processed sent by the gas stove through the wireless communication module. The range hood forms cooking input parameters according to the food weight, cooking process type and food type to obtain target cooking data matching the cooking input parameters in the local storage, wherein the target cooking data includes the odor type, odor concentration, cooking temperature curve and fire control data matching the cooking input parameters, and the cooking temperature is the temperature corresponding to the cooking fire. Then, the range hood sends the acquired target cooking data to the gas stove for cooking.

[0090] In step 15), the gas stove is provided with a fire power start device, a fire power control device and a fire power shut-off device to control the cooking fire power during the cooking process, wherein the fire power start device is used to turn on the fire power on the gas stove and control the range hood to automatically turn on; the fire power control device controls the size of the fire power in real time through the received signal; the fire power shut-off device automatically shuts off the fire power through the received signal, and can also shut off the fire power manually. After the gas stove receives the target cooking data sent by the range hood, the fire power start device is started to the on state, and the user can start cooking. During the cooking process, the fire power control device in the gas stove controls the cooking fire power size according to the target cooking data, thereby automatically adjusting the size of the fire power during the cooking process, making it convenient for the user to cook.

[0091] In step 16), when the user is cooking, when the fire starting device is started to the on state, the gas stove starts to record the cumulative cooking time from this moment. If the gas stove determines that the current cumulative cooking time is greater than or equal to the target cooking time corresponding to the target cooking data, it means that the cooking is completed, the fire shutoff device of the gas stove is started to the off state, the gas stove is switched to the off state, and the range hood is also switched to the off state, and the user ends cooking.

[0092] In one embodiment, after step 15) and before step 16), the following steps are included:

[0093] The range hood is further used to obtain current cooking parameters; the current cooking parameters include current odor type, current odor concentration and current cooking temperature;

[0094] If it is determined that the current odor concentration exceeds a preset first odor concentration threshold, a first detection time is obtained, the current cooking temperature is reduced by a preset temperature adjustment value to obtain a first adjustment cooking temperature value, and a firepower corresponding to the first adjustment cooking temperature value is maintained within a preset first time period;

[0095] If it is determined that the current cumulative cooking time is equal to the sum of the first detection time and the preset first duration, obtaining a first standard cooking temperature corresponding to the current cumulative cooking time in the target cooking data;

[0096] The gas stove is also used to control the cooking fire power according to the first standard cooking temperature.

[0097] In this embodiment, the range hood is provided with an infrared temperature sensor and an odor detection device, and the cooking temperature during the cooking process is obtained by the infrared temperature sensor, and the odor type and odor concentration during the cooking process are obtained by the odor detection device. When the user is cooking, the food will undergo a chemical reaction during the cooking process to form volatile compounds, and the range hood obtains the current odor type, current odor concentration and current cooking temperature, wherein the current food cooking state of the food can be judged by the current odor type and current odor concentration, such as the current food cooking state is good, the food cooking state is poor, the food cooking state is burnt, etc.

[0098] The range hood obtains the corresponding preset first odor concentration threshold value according to the current odor type, and determines the magnitude relationship between the current odor concentration and the preset first odor concentration threshold value. If the range hood determines that the current odor concentration exceeds the preset first odor concentration threshold value, it means that the current firepower is too large and the food is about to burn. In order to prevent the firepower from continuing to be too large to make the food burn, the range hood obtains the first detection time, and starts recording the cumulative cooking time when the firepower starting device is started to the on state. The corresponding cumulative cooking time when the range hood determines that the current odor concentration exceeds the preset first odor concentration threshold value is the first detection time. Then, the range hood reduces the current cooking temperature by the preset temperature adjustment value to obtain the first adjusted cooking temperature value. For example, if the preset temperature adjustment value is 10°C, the current cooking temperature is reduced by 10°C to obtain the first adjusted cooking temperature value. The firepower control device controls the firepower size according to the first adjusted cooking temperature value, and the gas stove maintains the firepower size corresponding to the first adjusted cooking temperature value within the preset first time length. The preset first time length can be set to 3min, 5min, etc., so as to reduce the cooking firepower and avoid excessive firepower. Finally, if the range hood determines that the current cumulative cooking time is equal to the sum of the first detection time and the preset first duration, it obtains the first standard cooking temperature corresponding to the current cumulative cooking time in the target cooking data and sends the first standard cooking temperature to the gas stove.

[0099] When the gas stove receives the first standard cooking temperature sent by the range hood, it controls the cooking fire power according to the first standard cooking temperature, so that during the cooking process from the current cumulative cooking time to the end of cooking, the gas stove can continue to control the cooking fire power according to the target cooking data, thereby completing the cooking.

[0100] In one embodiment, the range hood is further configured to obtain the current cooking parameters and further include:

[0101] The range hood is further configured to obtain a second detection time if it is determined that the current odor concentration does not exceed a preset second odor concentration threshold, increase the current cooking temperature by a preset temperature adjustment value to obtain a second adjusted cooking temperature value, and maintain a firepower corresponding to the second adjusted cooking temperature value within a preset second time period;

[0102] If it is determined that the current cumulative cooking time is equal to the sum of the second detection time and the preset second duration, obtaining a second standard cooking temperature corresponding to the current cumulative cooking time in the target cooking data;

[0103] The gas stove is also used to control the cooking fire power according to the second standard cooking temperature.

[0104] In this embodiment, the range hood obtains the corresponding preset second odor concentration threshold value according to the current odor type, and determines the magnitude relationship between the current odor concentration and the preset second odor concentration threshold value. If the range hood determines that the current odor concentration does not exceed the preset second odor concentration threshold value, it means that the current firepower is too small, and the food has not reached the food cooking state corresponding to the current cooking cumulative time, such as the food is not cooked. The range hood obtains the second detection time, and starts recording the cooking cumulative time when the firepower starting device is started to the on state. The cooking cumulative time corresponding to when the range hood determines that the current odor concentration does not exceed the preset second odor concentration threshold value is the second detection time. Then, the range hood increases the current cooking temperature by the preset temperature adjustment value to obtain the second adjusted cooking temperature value, and the firepower control device controls the firepower size according to the second adjusted cooking temperature value, and the gas stove maintains the firepower size corresponding to the second adjusted cooking temperature value within the preset second time length, and the preset second time length can be set to 3min, 5min, etc., so as to increase the cooking firepower so that the food reaches the standard food cooking state. Finally, if the range hood determines that the current cumulative cooking time is equal to the sum of the second detection time and the preset second time length, it obtains the second standard cooking temperature corresponding to the current cumulative cooking time in the target cooking data and sends the second standard cooking temperature to the gas stove.

[0105] When the gas stove receives the second standard cooking temperature sent by the range hood, the cooking firepower is controlled accordingly according to the second standard cooking temperature, so that during the cooking process corresponding to the current cooking cumulative time to the end of cooking, the gas stove can continue to control the cooking firepower according to the target cooking data, thereby completing cooking. Thus, through the two-way linkage between the gas stove and the range hood, the odor type, odor concentration and cooking temperature during the cooking process are monitored and analyzed, thereby matching the optimal parameters for food cooking, automatically adjusting the firepower during the cooking process in real time, and ensuring that the food cooking effect reaches a stable and good state.

[0106] In one embodiment, after step 15) and before step 16), the method further includes:

[0107] The range hood is also used to collect and save cooking pictures according to a preset picture collection cycle through an image recognition device.

[0108] In this embodiment, when the user is cooking and the food is not covered during the cooking process, auxiliary monitoring can also be performed through the image recognition device in the range hood. The range hood collects the cooking pictures of the food during the cooking process through the image recognition device according to the preset picture collection cycle, and saves the cooking pictures, so as to further collect the color, shape and state of the food based on the cooking pictures, call the data in the local storage of the range hood, match the fire control data, such as switching from high fire to low fire, and the range hood sends the fire control data to the gas stove, so that the fire control device of the gas stove can automatically control the fire according to the fire control data to ensure that the food cooking effect reaches a stable and good state.

[0109] In one embodiment, when the intelligent cooking system is used to implement the intelligent control method of the intelligent cooking system, after step 16), it further includes:

[0110] The range hood is further configured to obtain update data from the cloud server if the range hood detects that the current system time satisfies a preset update condition, and to update the cooking data in the local storage repository according to the update data.

[0111] In this embodiment, see Figure 4 , Figure 4 The application scenario diagram of the intelligent cooking system provided in this embodiment, the intelligent cooking system includes a range hood 11 and a gas stove 12, the range hood 11 is communicatively connected to the cloud server 13, in order to update the data in time so as to update the cooking data stored in the range hood 11 in time, if the range hood 11 detects that the current system time meets the preset update conditions, the range hood 11 obtains the update data of the cloud server 13, and updates the cooking data in the local storage repository according to the update data.

[0112] The intelligent cooking system provided by the embodiment of the present invention, when used to implement the intelligent control method of the intelligent cooking system, can automatically adjust the firepower of the gas stove during cooking through the two-way linkage of the gas stove and the range hood, making the range hood cooking process more intelligent. It can also monitor and analyze the odor type, odor concentration and cooking temperature during the cooking process, thereby matching the optimal parameters for food cooking, automatically adjusting the firepower during the cooking process in real time, and ensuring that the food cooking effect reaches a stable and good state. The present invention makes the range hood cooking process more intelligent and more convenient for users to use.
