[0051] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0052] Here, exemplary embodiments are described in detail, and examples thereof are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application.

[0053] The term "and / or" in this article is used to describe the association relationship of associated objects, specifically indicating that there may be three relationships. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone.

[0054] The boiling identification method of the embodiment of the present application can be applied to any scenario involving cooking.

[0055] Cookers are appliances used in the kitchen to cook food. They have a long history and come in many varieties. With the development of technology, the design and functions of cookers have also evolved. With the development of the Internet of Things and smart home technologies, smart cookers have gradually entered the market. These cookers are usually equipped with smart control systems that can be remotely controlled and monitored via mobile phones or tablets.

[0056] Smart stoves may also have functions such as automatic adjustment of fire power, timed cooking, and recipe recommendations, which greatly facilitates users' daily cooking.

[0057] As people's living needs improve, they have higher and higher requirements for the functional diversity of stoves. When using current stoves, users need to keep an eye on the changes in the ingredients in the pot so that they can perform the next cooking operation according to the conditions of the ingredients in the pot. This requires users to stay by the stove and observe at all times, which wastes a lot of users' time and can no longer meet the users' increasingly fast pace of life.

[0058] In the related art, the method for judging boiling of the stove is generally to measure the temperature by the stove temperature probe, which is located at the center of the burner. The principle is to evaluate the temperature of the liquid in the pot based on the temperature probe detecting the temperature of the bottom surface of the pot. If the temperature of the liquid in the pot reaches the boiling point, it is determined that the food in the pot has boiled.

[0059] This solution has at least the following disadvantages:

[0060] 1) There are requirements for the pot: for example, the pot must have a flat bottom, or the material and thickness of the pot must be within a certain range in order to make a more accurate boiling judgment.

[0061] 2) There are requirements for the water in the pot: for example, only room temperature water can be used, hot water, ice water or water added in the middle cannot be used; the ingredients cannot be frozen, etc.; because these situations will cause the temperature probe to measure the temperature inaccurately, which will lead to inaccurate boiling judgment results.

[0062] 3) There are requirements for the food in the pot: for example, it is required that ingredients cannot be added in the middle of the process, because after adding ingredients in the middle of the process, the temperature of the ingredients in the pot and the temperature at the bottom of the pot will be greatly different, which will lead to inaccurate boiling judgment results.

[0063] In order to solve at least one of the above problems, the embodiment of the present application provides a boiling identification solution, which determines the preset range corresponding to the weight change in the boiling state through the mapping relationship between the total weight loss of the container and the material in the container and the temperature change in the container during the heating process of the stove, obtains the weight change information of the container placed on the stove during the operation of the stove, and when the weight change information of the container is detected to be within the preset range, the system can issue a boiling prompt message in time. By using the weight change of the container placed on the stove to automatically identify whether the food in the container is boiling, and issue a prompt in time, this method is not affected by the water temperature in the container, the food temperature, the type of container, and whether water and food are added in the middle, the range hood is turned on, etc., which not only improves the accuracy of boiling judgment and effectively prevents the overflow of the pot caused by boiling, but also can timely remind the user to perform the next operation at the appropriate time, improve the safety and convenience of cooking, reduce the monitoring burden of the user, and improve the user experience.

[0075] like Figure 3 As shown, a stove 300 provided by the present application is provided, and the stove 300 at least includes a burner 301, a weight detector 302 and a control module 303, wherein:

[0076] The burner 301 is used to heat a container placed on the stove 300 during operation of the stove 300 . There may be one or more burners 301 .

[0077] The weight detector 302 is used to measure the weight of the container placed on the stove 300; optionally, the weight detector can display the weight information in real time to show the weight information to the user; and can also perform relevant calculations based on the collected weight information.

[0078] The control module 303 is connected to the burner 301 and the weight detector 302 respectively. The control module 303 is used to obtain the weight change information of the container placed on the stove 300 during the operation of the stove 300, and if it is determined that the weight change information is within a preset range, a boiling prompt message is issued.

[0079] In this embodiment, the stove 300 can be a gas stove, an electromagnetic stove, or an electric ceramic stove in a smart home appliance. The control module 303 of the stove 300 can execute all or part of the process of the method in any of the following embodiments to automatically identify whether the food in the container is boiling by using the weight change of the container placed on the stove 300, and issue a prompt in time. This method is not affected by the water temperature in the container, the food temperature, the type of container, whether water or food is added in the middle, the range hood is turned on, etc., which not only improves the accuracy of boiling judgment and effectively prevents the overflow of the pot caused by boiling, but also can timely remind the user to perform the next operation at the appropriate time, improve the safety and convenience of cooking, reduce the monitoring burden of the user, and improve the user experience.

[0080] In one embodiment, the stove 300 may further include: one or more of a temperature detection module, a function panel, and a buzzer.

[0081] The temperature detection module, the function panel, and the buzzer may be electrically connected to the control module 303 , respectively.

[0082] The temperature detection module may be disposed at the center of the burner 301 to measure the temperature of the cookware. There may be one or more temperature detection modules.

[0083] Please see Figure 4 , which is a boiling identification method according to an embodiment of the present application, the method can be Figure 1 The electronic device 1 shown is used to perform and can be applied to Figure 2 and Figure 3 In the stove control scenario shown in , the accuracy of boiling judgment is improved, the overflow of the pot caused by boiling is effectively prevented, and the user can be reminded in time to perform the next operation at the appropriate time, thereby improving the safety and convenience of cooking, reducing the monitoring burden of the user, and improving the user experience. In this embodiment, the terminal 220 is used as an execution end as an example, and the method includes the following steps:

[0084] Step 401: during the operation of the stove, obtaining weight change information of a container placed on the stove;

[0085] Step 402: If it is determined that the weight change information is within a preset range, a boiling prompt message is issued.

[0086] In this embodiment, the weight change information refers to the change information of the total weight of the container and the material contained in the container. The preset range is used to determine whether the material in the container is boiling. The preset range is determined according to the mapping relationship between the total weight loss of the container and the material in the container and the temperature change in the container during the heating process of the stove. The mapping relationship may include the total weight change rate of the container and the material in the container when the material in the container is boiling.

[0087] In actual use, when the material in the container heated by the stove boils, there is a stable and synchronous turning point between the temperature in the container and the total weight loss, based on which the boiling state can be accurately identified.

[0088] like Figure 5 As shown, it is a schematic diagram of the mapping relationship between the measured temperature in the pot and the weight loss during the boiling process provided by an embodiment of the present application. The experimental data takes the boiling process of 800g of water in the pot as an example. The horizontal axis is the data sampling time during the heating process of the stove (starting from 0:00:01, the first second of heating, to 0:10:21, a total of 10 minutes and 21 seconds), and the vertical axes are temperature and weight, respectively.

[0089] It can be seen that when the water in the heated pot boils, the total weight loss of the pot and water has a stable time turning point. At this time turning point, the total weight of the pot and water drops sharply, and the measured temperature in the pot stabilizes near the boiling point. Moreover, after the turning point, when the stove continues to heat the pot, the total weight of the pot and water changes with time in a linear manner, while the measured temperature in the pot remains near the boiling point and tends to remain unchanged.

[0090] like Figure 6 As shown, it is a schematic diagram of the mapping relationship between the measured temperature in the pot and the weight loss during the boiling process provided by an embodiment of the present application. The experimental data takes the boiling process of the material in the pot including 500g of food + 1500g of water as an example. The horizontal axis is the heating time of the stove (from the first second of heating at 0:00:01 to 0:10:39, a total of 10 minutes and 39 seconds), and the vertical axes are temperature and weight, respectively.

[0091] It can be seen that when the material in the heated pot boils, the total weight loss of the pot and the material has a stable time turning point. At this time turning point, the total weight of the pot and the material drops sharply, and the temperature in the pot stabilizes near the boiling point. Moreover, after the turning point, when the stove continues to heat the pot, the total weight of the pot and the material changes with time in a linear manner, that is, after boiling, the total weight change rate is basically unchanged, while the temperature in the pot remains near the boiling point and tends to be unchanged.

[0092] comprehensive Figure 5 and Figure 6The experimental data show that no matter what kind of material is in the pot, there is a synchronous time turning point between the temperature in the pot and the total weight loss of the pot and the material during boiling. That is, when the material in the heated container boils, the total weight change rate of the container and the material remains basically unchanged. Based on this mapping relationship, the preset range of weight change during boiling can be set, and the boiling state can be accurately identified.

[0093] The preset range corresponding to the weight change in the boiling state is determined based on the mapping relationship between the total weight loss of the container and the material in the container during the heating process of the stove and the temperature change in the container. The weight change information of the container placed on the stove is obtained during the operation of the stove. When the weight change information of the container is detected to be within the preset range, the system can issue a boiling prompt in time. The weight change of the container placed on the stove is used to automatically identify whether the food in the container is boiling and issue a prompt in time. This method is not affected by the water temperature in the container, the food temperature, the type of container, whether water or food is added in the middle, or the range hood is turned on. It not only improves the accuracy of boiling judgment and effectively prevents the overflow caused by boiling, but also can promptly remind the user to perform the next operation at the appropriate time, improve the safety and convenience of cooking, reduce the user's monitoring burden, and improve the user experience.

[0094] In one embodiment, before step 401, the method may further include: in response to an operation instruction for the stove, obtaining current cooking information of the stove, and executing step 401 when the current cooking information meets a preset condition.

[0095] In this embodiment, the current cooking information includes but is not limited to one or more of the cooking function information currently executed by the stove, the current cooking gear information, the current cooking firepower information, and the current temperature information of the container; the preset condition is used to determine whether the current cooking information of the stove needs to perform the boiling judgment process, which can be set according to actual needs. Before performing the boiling judgment, firstly, according to the user's operation instructions to the stove, the user's current cooking behavior is identified, such as identifying whether the user is currently using the stove to cook manually, or using the main function of the stove, automatic recipes, etc., and then the current cooking information of the stove is obtained. For example, as long as the user uses the stove, there must be an ignition operation, and it can be further identified whether the gear or operating power of the stove currently running meets the preset condition. At this time, the preset condition can be a preset running gear or a specific running power. For example, if the stove is identified to use a certain set power or above for heating, it is determined that the current cooking information meets the preset condition, and step 401 is executed to perform boiling judgment.

[0096] Specifically, taking a gas stove as an example, the preset conditions may include: the operating power of the gas stove is 2500W or above, or the gas stove is currently operating at gear 5 or above, or the gas stove is currently operating at medium or high gear. If the acquired current cooking information meets any of the above preset conditions, it can be determined to start executing step 401 to perform the boiling judgment process.

[0097] Optionally, the preset condition may also include that the current temperature of the container reaches a certain temperature threshold T. After recognizing the user's cooking behavior, the current temperature information of the bottom of the container may also be identified to determine whether the current temperature information reaches a certain temperature threshold T. If so, step 401 is executed to perform boiling determination. For example, if it is recognized that the temperature of the stove temperature probe reaches 80° C. or above, boiling determination is started.

[0098] This embodiment triggers boiling judgment through preset conditions, avoids resource waste caused by real-time judgment, and improves the effectiveness of boiling judgment.

[0099] In one embodiment, the cooker is provided with a weight detector, which is used to measure the weight of the container placed on the cooker; step 401 may specifically include: using the weight detector to collect weight change information of the container placed on the cooker at a preset frequency.

[0100] In this embodiment, the stove can be equipped with a weight detector, which can weigh the container placed on the stove. The weight obtained by the weight detector includes the weight of the container and the weight of the material contained in the container. For example, if the container placed on the stove is a pot, the weight obtained by the weight detector includes the sum of the weight of the pot and the weight of the ingredients in the pot. In actual scenarios, the weight detector can weigh the pot and the food, water, ingredients, etc. inside, and can be configured with weighing range (example: 0-10kg), precision (example: 1g), peeling and other functions.

[0101] When measuring the weight of a container, a weight detector may be configured to collect weight change information of the container placed on the cooker at a preset frequency, thereby saving data calculation and storage space.

[0102] In one embodiment, step 401 may specifically include: calculating the weight change of the container within a preset time period, and the weight change information includes the weight change. In this case, step 402 specifically includes: when the weight change is within a preset range, issuing a boiling prompt message.

[0103] In this embodiment, the weight change information can be represented by the weight change within a fixed time period, and the preset time period can be set according to actual needs. For example, the weight change information can be represented by calculating the total weight change Δm(20s) of the container and the material in the container within 20 seconds.

[0104] like Figure 7 As shown, Figure 5 The schematic diagram of the total weight change rate of the pot and the water in the pot during the boiling process of water corresponding to the illustrated embodiment is as a function of time, with the weight loss every 20 seconds representing the total weight change rate as an example. The experimental data takes the boiling process of 800g of water in the pot as an example. The horizontal axis is the data sampling time during the heating process of the stove (from 0:00:01, the first second of heating, to 0:25:41, a total of 25 minutes and 41 seconds), and the vertical axis is the weight.

[0105] like Figure 8 As shown, Figure 6 The schematic diagram of the total weight change rate of the cookware and the material in the cookware during the boiling process corresponding to the illustrated embodiment is a schematic diagram of the total weight change rate of the cookware and the material in the cookware changing with time, taking the weight loss every 20 seconds as an example to represent the total weight change rate. The experimental data takes the boiling process of the material in the cookware including 500g of food + 1500g of water as an example. The horizontal axis is the heating time of the cooker (from 0:00:01, the first second of heating, to 0:10:45, a total of 10 minutes and 45 seconds), and the vertical axis is the weight.

[0106] Depend on Figure 7 and Figure 8 As shown in FIG. 1 , since the water or the mixture of water and food in the pot has an obvious temperature turning point after being heated (i.e., it quickly rises to 100°C boiling state and then keeps the temperature constant), the total weight change rate of the pot and the material in the pot also has a synchronous turning point (e.g., Figure 5 As shown, the weight is kept stable first, and the change per unit time is small, Δm(20s) = 0 ~ 4g. When it is around 100℃, the water boils, and the liquid water evaporates into the environment, causing the weight to drop sharply (Δm(20s) ≥ 8g). Therefore, the law of this turning point can be used to determine the boiling condition in the pot. For example, the total weight change Δm(20s) of the container and the material in the container within 20 seconds can be used to characterize the weight change information. Taking the preset range as 8g as an example, if Δm(20s) ≥ 8g is detected, it is determined that the material in the pot is boiling at this time. The calculation interval time of the weight change (i.e., the preset duration) can be set to 5s, 10s, 20s, 30s, etc. according to the actual situation. The data collection frequency, data storage space, and judgment accuracy can be comprehensively considered to select a suitable interval time to determine boiling and improve flexibility.

[0107] like Fig. 9 FIG. 1 is a schematic diagram of an actual application scenario of a boiling state recognition method based on a cooker provided in an embodiment of the present application. The total weight change Δm(20s) of the cookware and the material in the cookware within 20 seconds is used to represent the weight change information, and the preset range is set to [12g, +∞) as an example. The method includes:

[0108] Step 901: First, the user selects a stove function, such as selecting any one of the stove's main functions, automatic recipes, and manual cooking.

[0109] Step 902: In response to the user's operating instructions, a high fire signal (gear or power) is obtained from the stove, or the temperature probe detects a certain temperature T (set temperature threshold T) and maintains it for a period of time, triggering the boiling state recognition process.

[0110] Step 903: The weight detector obtains the total weight data of the cookware and the material in the cookware at regular intervals (eg, 20 seconds), and calculates the total weight change Δm(20 seconds) of the cookware and the material in the cookware.

[0111] Step 904: Determine whether Δm(20s) is greater than or equal to 8g. If so, proceed to step 905; otherwise, return to step 903.

[0112] Step 905: Sending a boiling reminder message to remind that the current pot is boiling, or automatically switching the program to avoid overflowing due to boiling.

[0113] Step 906: The user can continue the next step of cooking according to the reminder information.

[0114] For details of each step of the above method, please refer to the relevant description of the above embodiment, which will not be repeated here.

[0115] In an optional embodiment, in order to avoid misjudgment caused by the user adding water or ingredients to the pot during the cooking process, the preset range for boiling identification can be set as an interval range, such as setting a judgment interval of Δm(20s). For example, it is determined whether 8g≤Δm(20s)≤18g is satisfied. If so, boiling is determined, otherwise heating can be continued, thereby improving the accuracy of boiling judgment.

[0116] In an optional embodiment, in order to avoid misjudgment caused by the user adding water or ingredients to the pot during the cooking process, the boiling condition can be determined through multiple boiling recognition judgments. For example, when it is recognized for the first time that Δm(20s) satisfies 8g≤Δm(20s)≤18g, it can be judged once or several times after a period of time (for example, 5s). When multiple judgments all satisfy 8g≤Δm(20s)≤18g, boiling is determined. Otherwise, heating can be continued, thereby improving the accuracy of boiling judgment and avoiding misjudgment.

[0117] like Fig.10 FIG. 1 is a schematic diagram of a practical application scenario of a method for identifying a boiling state of a stove provided in an embodiment of the present application. The method includes:

[0118] Step 1001: the stove starts heating the placed pot and obtains the current cooking information of the stove;

[0119] Step 1002: Determine whether the preset conditions are met. Assume that the gas pressure currently used by the stove is 2000Pa. The corresponding preset condition under this gas pressure value is that the operating gear of the stove must be greater than or equal to gear 5 to trigger boiling recognition. Then determine whether the current operating gear of the stove is greater than or equal to gear 5. If so, proceed to step 1003, otherwise proceed to step 1008.

[0120] Step 1003: Continue to determine whether the temperature measured by the stove temperature probe is greater than or equal to 80°C. If so, proceed to step 1004, otherwise continue to detect the temperature.

[0121] Step 1004: The stove continues heating.

[0122] Step 1005: Detect the total weight change Δm(20s) of the cookware and the material in the cookware, and determine whether Δm(20s) satisfies 8g≤Δm(20s)≤18g. If yes, proceed to step 1006, otherwise continue to control the stove to heat.

[0123] Step 1006: After an interval of 5 seconds, the total weight change Δm(20s) of the cookware and the material in the cookware is detected again, and it is determined again whether Δm(20s) satisfies 8g≤Δm(20s)≤18g. If so, proceed to step 1007; otherwise, continue to detect and determine.

[0124] Step 1007: When boiling is confirmed, a boiling prompt may be issued.

[0125] Step 1008: If not, no boiling determination is made.

[0126] For details of each step of the above method, please refer to the relevant description of the above embodiment, which will not be repeated here.

[0127] In one embodiment, step 401 may further include: obtaining the initial weight of the container initially placed on the cooker; during the operation of the cooker, calculating the weight difference between the current weight of the container and the initial weight, and the weight change information includes the weight difference. In this case, step 402 may further include: when the weight difference is within a preset range, issuing a boiling prompt message.

[0128] In this embodiment, based on the turning point of the temperature of the water or the mixture of water and food in the pot after heating in the aforementioned embodiment (i.e., quickly heating to 100°C and then keeping the temperature constant), the total weight change of the pot and the material in the pot also has a synchronous turning point. The weight difference compared with the initial weight can also be used to make a boiling judgment. For example, m is the current weight of the pot and the material in the pot recorded every 20 seconds, and m0 is the initial weight of the pot and the material in the pot. Assuming that the preset range is greater than or equal to 12g (or interval: [12g, 22g]), when it is detected that m0-m≥12g (or 12g≤m0-m≤22g), it is determined that the pot is boiling, and a boiling prompt can be issued so that the user can take corresponding measures in time when the liquid is about to boil to avoid long-term high-temperature heating.

[0129] like Fig.11 FIG. 1 is a schematic diagram of an actual application scenario of a boiling state recognition method based on a stove provided by an embodiment of the present application. The weight difference between the current weight of the pot and its internal material and the initial weight of the pot when it is initially placed on the stove is used to represent the weight change information. The preset range is set to [12g, +∞) as an example. The method includes:

[0130] Step 1101: First, the user selects a stove function, such as selecting any one of the stove's main functions, automatic recipes, and manual cooking;

[0131] Step 1102: In response to the user's operating instructions, a high fire signal (gear or power) is obtained from the stove, or the temperature probe detects a certain temperature (a set temperature threshold T) and maintains it for a period of time, triggering the boiling state recognition process.

[0132] Step 1103: Record the total weight m of the cookware and the material in the cookware at certain intervals, and compare it with the initial weight m0 to calculate the weight difference m0-m.

[0133] Step 1104: Determine whether m0-m≥12g is satisfied. If so, proceed to step 1105; otherwise, the stove continues heating and returns to step 1103.

[0134] Step 1105: Sending a boiling reminder message to remind that the current pot is boiling, or automatically switching the program to avoid overflowing due to boiling.

[0135] Step 1106: The user can continue the next step of cooking according to the reminder information.

[0136] For details of each step of the above method, please refer to the relevant description of the above embodiment, which will not be repeated here.

[0137] In one embodiment, the method further includes: in response to an adjustment instruction for boiling detection sensitivity, adjusting a frequency of acquiring weight change information and / or adjusting a frequency of comparing weight change information with a preset range.

[0138] In this embodiment, different application scenarios may have different requirements for the sensitivity of boiling detection. By adjusting the acquisition frequency and the comparison frequency, the system can flexibly adapt to different scenario requirements and provide more accurate and reliable detection results. When high-sensitivity detection is not required, reducing the acquisition frequency and the comparison frequency can reduce the consumption of system resources, such as processor load and power consumption, thereby extending the service life of the device and improving overall efficiency.

[0139] Users can customize the sensitivity of boiling detection. A sensitivity adjustment button can be provided on the control panel of the stove, or a sensitivity adjustment button can be provided on the terminal APP (Application). For example, the sensitivity can be set to: faster, moderate, slower and other options. The faster the sensitivity, the more sensitive the boiling recognition is, and the higher the boiling recognition accuracy. Users can adjust the sensitivity of boiling detection according to their needs to improve the interactive experience.

[0140] Specifically, by adjusting the acquisition frequency of weight change information, the subtle weight changes during the boiling process of the liquid can be captured more accurately, thereby improving the accuracy of boiling detection. By adjusting the comparison frequency of weight change information with a preset range, it is possible to quickly respond to changes in the external environment and conditions during the boiling identification process, thereby improving the accuracy of boiling detection.

[0141] Specifically, boiling detection with faster sensitivity can be achieved by increasing the frequency of obtaining the weight change information of the container and / or increasing the frequency of comparing the weight change information with a preset range, and boiling detection with slower sensitivity can be achieved by reducing the frequency of obtaining the weight change information of the container and / or reducing the frequency of comparing the weight change information with a preset range. For example, the sensitivity corresponding to the weight change Δm (20s) is slower than the sensitivity corresponding to the weight change Δm (10s), and the sensitivity corresponding to comparing m0-m with the preset range [12g, +∞) once every 10s is faster than the sensitivity corresponding to comparing m0-m with the preset range [12g, +∞) once every 30s. The system can change the detection parameters in real time according to the adjustment instructions, making the boiling detection process more dynamic and intelligent, and can quickly respond to changes in the external environment and conditions, and provide timely feedback and control.

[0142] In one embodiment, the method further comprises: in response to an adjustment instruction for boiling detection sensitivity, adjusting the size of a boundary value of a preset range according to the weight change information;

[0143] In this embodiment, the sensitivity of boiling recognition can be changed by adjusting the size of the preset range, so as to flexibly adapt to different cooking environments and needs and improve the accuracy and reliability of boiling detection. Specifically, when the user adjusts the boiling detection sensitivity, the system will automatically adjust the boundary value of the preset range according to the real-time monitored weight change information, so that boiling detection is more accurate and avoids false alarms or missed alarms. This not only improves the user experience, but also effectively prevents overflowing pots or other cooking accidents caused by inaccurate boiling detection.

[0144] For example, the sensitivity of the preset range [12g, +∞) corresponding to Δm(20s) is lower than the sensitivity of the preset range [7g, +∞) corresponding to Δm(20s). The sensitivity of the preset range [8g, 18g] corresponding to Δm(20s) is lower than the sensitivity of the preset range [7g, 17g] corresponding to Δm(20s).

[0145] The sensitivity of m0-m in the preset range [11g, +∞) is faster than that of m0-m in the preset range [12g, +∞). The sensitivity of m0-m in the preset range [11g, 21g] is faster than that of m0-m in the preset range [12g, 22g].

[0146] like Fig.12 As shown, it is a schematic diagram of a setting scheme of boiling identification sensitivity provided in an embodiment of the present application. It is assumed that different sensitivity adjustments can be divided into three levels: faster, moderate, and slower, wherein the parameter settings are as follows:

[0147] The faster sensitivity can be set according to any of the following schemes to perform boiling identification judgment with faster sensitivity:

[0148] 1. If the condition Δm(20s)≥7g or Δm(10s)≥4g is met, boiling is determined;

[0149] 2. Boiling is determined when the condition m0-m ≥ 11 g (the current weight is compared with the initial weight every 20 seconds) or the condition m0-m ≥ 12 g (the current weight is compared with the initial weight every 10 seconds) is met.

[0150] Moderate sensitivity can be set according to any of the following schemes to perform boiling identification and judgment with moderate sensitivity:

[0151] 1. Boiling is determined when the condition Δm(20s)≥8g is met;

[0152] 2. Boiling is determined when the condition m0-m ≥ 12 g (the current weight is compared with the initial weight every 20 seconds).

[0153] The slower sensitivity can be set according to any of the following schemes to perform boiling identification judgment with a slower sensitivity:

[0154] 1. If the condition Δm(20s)≥9g or Δm(30s)≥12g is met, boiling is determined;

[0155] 2. Boiling is determined when the condition m0-m ≥ 13 g (the current weight is compared with the initial weight every 20 seconds) or the condition m0-m ≥ 12 g (the current weight is compared with the initial weight every 30 seconds) is met.

[0156] In the above sensitivity parameter setting scheme, if the weight change of the container within the preset time is used to represent the weight change information, the scheme 1 corresponding to each sensitivity level can be used for parameter configuration. If the weight difference between the current weight and the initial weight of the container is used to represent the weight change information, the scheme 2 corresponding to each sensitivity level can be used for parameter configuration. The specific settings can be based on your actual needs to improve the flexibility of the sensitivity configuration scheme.

[0157] In an optional embodiment, after boiling is identified, a buzzer reminder, an APP reminder, a local page reminder, etc. can be used to remind the user to add ingredients (such as cooking noodles, dumplings, etc.) or prompt the user to start a managed cooking (making soup, braising, etc.) mode, thereby improving the intelligent experience of the stove.

[0158] As shown in Tables 1 to 3 below, examples of simulations of boiling identification solutions based on embodiments of the present application in actual scenarios are shown:

[0159] Table 1. Simulated boiling water

[0160]

[0161] Table 2. Simulated soup making

[0162]

[0163] Table 3. Simulated stewing

[0164]

[0165] It can be seen that the boiling recognition scheme of the embodiment of the present application uses the turning point of the temperature and weight loss curve during boiling to judge the boiling point. It is applicable to scenes such as boiling water, steaming, making soup, and braising. When the boiling prompt is issued, the temperature in the pot has reached 96-100°C, and the deviation from the obvious boiling observed by the naked eye is within +1min. Containers include but are not limited to coated pots, iron pots, enamel pots, casseroles, steamers and other pots, and pots with or without lids can be used. During the boiling recognition process, it does not matter whether the range hood is turned on or not, and there are no restrictions on the water temperature and pot temperature in the pot. It is applicable to situations such as whether food is placed, etc., which improves the safety and convenience of cooking, reduces the user's monitoring burden, and improves the user experience.

[0166] Please see Fig.13 , which is a boiling identification device 1300 of an embodiment of the present application, the device can be applied to Figure 1 The electronic device 1 shown can be applied to Figure 2 and Figure 3 In the stove control scenario shown in the figure, it can not only improve the accuracy of boiling judgment and effectively prevent the overflow of the pot caused by boiling, but also promptly remind the user to perform the next operation at the appropriate time, thereby improving the safety and convenience of cooking, reducing the user's monitoring burden, and improving the user experience.

[0168] The acquisition module 1301 is used to acquire the weight change information of the container placed on the cooker during the operation of the cooker;

[0169] The determination module 1302 is used to issue a boiling prompt message if it is determined that the weight change information is within a preset range.
