Description

Technical Field

[0001] This invention relates to the field of smart home appliance technology, and in particular to a control method, control device, smart cooktop, and storage medium for a smart cooktop. Background Technology

[0002] Cooktops are essential household appliances, and with the continuous development of smart appliances, cooktops are also gradually moving towards intelligence and precision. When cooking with traditional cooktops, users typically control the heat and cooking time manually by adjusting the flame. If a user leaves the cooking area for an extended period when boiling water, the water may boil over, requiring continuous monitoring of the entire cooking process. The lack of automatic boiling detection significantly reduces the user experience. Summary of the Invention

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a control method, control device, intelligent stove, and storage medium for an intelligent stove, which can more accurately and reliably identify the boiling state, effectively improve the intelligence level of the stove, and greatly enhance the user experience.

[0004] In a first aspect, embodiments of the present invention provide a control method for an intelligent cooktop, wherein the cooktop is equipped with a temperature sensor for detecting the temperature of the bottom of a pot, and the control method includes:

[0005] Obtain the temperature of the bottom of the pot from the temperature sensor;

[0006] When the temperature of the bottom of the pot is in the temperature rising stage, the temperature rise change time of the bottom of the pot is obtained, wherein the temperature rise change time is used to reflect the time required for the bottom of the pot to rise to a preset unit temperature.

[0007] Calculate the boiling point identification time based on the temperature rise change time;

[0008] The highest value of the pot bottom temperature during the temperature rise phase is determined as the boiling point temperature, and the first duration of recording the boiling point temperature is started.

[0009] When the first duration is greater than or equal to the boiling point recognition time, the cooking state of the pot is determined to be boiling, and the current heat of the stove is reduced.

[0010] The control method for an intelligent stove provided according to embodiments of the present invention has at least the following beneficial effects: By acquiring the bottom temperature of the pot from a temperature sensor, the temperature of the food being cooked in the pot can be detected in real time. When the bottom temperature is in the temperature rising phase, the time required for the bottom temperature to rise to a preset unit temperature is acquired, i.e., the temperature rise change time of the bottom temperature is acquired. The boiling point identification time is calculated based on the temperature rise change time. Then, the highest value of the bottom temperature during the temperature rising phase is determined as the boiling point temperature. Simultaneously, the first duration of recording the boiling point temperature begins. When the first duration is greater than or equal to the boiling point identification time, it indicates that the bottom temperature has reached the boiling point. Maintaining the boiling point temperature for a certain period of time determines the cooking state of the pot as boiling, reducing the impact of external interference and allowing for more accurate and reliable identification of the boiling state, resulting in more precise control. Furthermore, using only a temperature sensor to detect the pot's bottom temperature significantly reduces costs. Additionally, after determining the boiling state, reducing the stove's current heat output achieves automatic flame control, minimizing food spillage and ensuring the stove's safe and reliable operation. Moreover, it eliminates the need for continuous user monitoring of the cooking process, effectively enhancing the stove's intelligence and greatly improving the user experience.

[0011] In the control method of the above-mentioned intelligent stove, the step of calculating the boiling point recognition time based on the temperature rise change time includes:

[0012] Multiply the temperature rise change time by a first preset value and add a second preset value to obtain the boiling point identification time.

[0013] In the above-mentioned control method for intelligent cooktops, after determining that the cooking state of the pot is boiling and controlling the current heat of the cooktop to decrease, the control method further includes:

[0014] When the temperature of the pot bottom is greater than a first preset temperature and continues for a first preset time, the stove is controlled to turn off, wherein the first preset temperature is obtained by adding a third preset value to the boiling point temperature.

[0015] In the above-mentioned control method for intelligent cooktops, the cooktop is further equipped with a proportional valve, and the control method further includes:

[0016] The opening degree of the proportional valve is increased to increase the current firepower of the stove;

[0017] Alternatively, the opening of the proportional valve can be reduced to decrease the current firepower of the stove.

[0018] The control method for the aforementioned smart stove also includes:

[0019] Obtain the current cooking recipe, wherein the cooking recipe includes at least one target temperature change curve, the target temperature change curve being used to reflect the correspondence between the target temperature at the bottom of the pot and time;

[0020] The current heat of the stove is controlled according to the temperature of the bottom of the pot, so that the current temperature change curve of the bottom of the pot over time tracks the target temperature change curve corresponding to the cooking recipe.

[0021] In the control method for the aforementioned smart cooktop, the cooking recipe includes multiple target temperature change curves corresponding to different cookware types, and the control method further includes:

[0022] During the process of tracking the current target temperature change curve with the current temperature change curve, when the first difference between the bottom temperature of the pot and the target temperature is greater than a preset difference, it is determined that the type of cookware has changed, and the target temperature change curve corresponding to the current type of cookware is re-determined. The preset difference is obtained by multiplying the bottom temperature of the pot by a fourth preset value.

[0023] The current temperature change curve is controlled to track the redefined target temperature change curve.

[0024] In the control method of the above-mentioned intelligent stove, the cooking recipe further includes multiple cooking steps, each of which has a preset target cooking time. The control method also includes:

[0025] Obtain the continuous running time of the stove in the current cooking step;

[0026] When the continuous running time is greater than or equal to the target cooking time, the next cooking step is triggered and the corresponding cooking step operation prompt information is output.

[0027] Alternatively, when the real-time area is greater than or equal to the preset trigger area, the next cooking step is triggered and the corresponding cooking step operation prompt information is output, wherein the real-time area is obtained by multiplying the second difference between the bottom temperature of the pot and the ambient temperature by the continuous running time.

[0028] In a second aspect, embodiments of the present invention provide an operation control device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the program to implement the control method described in the first aspect embodiment above.

[0029] The operation control device provided according to the embodiments of the present invention has at least the following beneficial effects: by acquiring the bottom temperature of the pot from the temperature sensor, the temperature of the food being cooked in the pot can be detected in real time. When the bottom temperature is in the temperature rising phase, the time required for the bottom temperature to rise to a preset unit temperature is acquired, i.e., the temperature rise change time of the bottom temperature is acquired. The boiling point identification time is calculated based on the temperature rise change time. Then, the highest value of the bottom temperature in the temperature rising phase is determined as the boiling point temperature. At the same time, the first duration of the boiling point temperature is recorded. When the first duration is greater than or equal to the boiling point identification time, it indicates that the bottom temperature has been maintained. By determining the boiling point temperature over a certain period of time, the cooking state of the pot is identified as boiling. This reduces the impact of external interference and allows for more accurate and reliable identification of the boiling state, resulting in more precise control. Furthermore, using only a temperature sensor to detect the temperature of the pot bottom significantly reduces costs. Additionally, once the boiling state is determined, the current heat of the stove is reduced, achieving automatic flame control. This reduces the risk of food overflowing, ensuring the safety and reliability of the stove. Moreover, it eliminates the need for continuous user observation of the entire cooking process, effectively enhancing the stove's intelligence and greatly improving the user experience.

[0030] Thirdly, embodiments of the present invention provide an intelligent stove, including the operation control device described in the second aspect of the embodiments above.

[0031] The intelligent cooktop provided by the embodiments of the present invention has at least the following beneficial effects: by acquiring the bottom temperature of the pot from a temperature sensor, the temperature of the food being cooked in the pot can be detected in real time. When the bottom temperature is in the temperature rising phase, the time required for the bottom temperature to rise to a preset unit temperature is acquired, i.e., the temperature rise change time of the bottom temperature is acquired. The boiling point recognition time is calculated based on the temperature rise change time. Then, the highest value of the bottom temperature during the temperature rising phase is determined as the boiling point temperature. At the same time, the first duration of the boiling point temperature is recorded. When the first duration is greater than or equal to the boiling point recognition time, it indicates that the bottom temperature has been maintained at that temperature. By determining the boiling point temperature over a certain period of time, the cooking state of the pot is identified as boiling. This reduces the impact of external interference and allows for more accurate and reliable identification of the boiling state, resulting in more precise control. Furthermore, using only a temperature sensor to detect the temperature of the pot bottom significantly reduces costs. Additionally, after determining the boiling state, the current heat of the stove is reduced, achieving automatic flame control. This reduces the risk of food overflowing, ensuring the safety and reliability of the stove. Moreover, it eliminates the need for users to continuously monitor the entire cooking process, effectively improving the stove's intelligence and greatly enhancing the user experience.

[0032] Fourthly, embodiments of the present invention provide a computer-readable storage medium storing computer-executable instructions for causing a computer to perform the control method described in the first aspect of the embodiments above.

[0033] The computer-readable storage medium provided according to embodiments of the present invention has at least the following beneficial effects: by acquiring the bottom temperature of the pot from a temperature sensor, the temperature of the food being cooked in the pot can be detected in real time. When the bottom temperature is in the temperature rising phase, the time required for the bottom temperature to rise to a preset unit temperature is acquired, i.e., the temperature rise change time of the bottom temperature is acquired. The boiling point identification time is calculated based on the temperature rise change time. Then, the highest value of the bottom temperature during the temperature rising phase is determined as the boiling point temperature. Simultaneously, the first duration of recording the boiling point temperature begins. When the first duration is greater than or equal to the boiling point identification time, it indicates that the bottom temperature has reached the boiling point. Maintaining the boiling point temperature for a certain period of time determines the cooking state of the pot as boiling, reducing the impact of external interference and allowing for more accurate and reliable identification of the boiling state, resulting in more precise control. Furthermore, using only a temperature sensor to detect the pot's bottom temperature significantly reduces costs. Additionally, after determining the boiling state, reducing the stove's current heat output achieves automatic flame control, minimizing food spillage and ensuring the stove's safe and reliable operation. Moreover, it eliminates the need for continuous user monitoring of the cooking process, effectively enhancing the stove's intelligence and greatly improving the user experience.

[0044] It is understood that the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0045] Cooktops are essential household appliances, and with the continuous development of smart appliances, cooktops are also gradually moving towards intelligence and precision. When cooking with traditional cooktops, users typically control the heat and cooking time manually by adjusting the flame. If a user leaves the cooking area for an extended period when boiling water, the water may boil over, requiring continuous monitoring of the entire cooking process. The lack of automatic boiling detection significantly reduces the user experience.

[0046] Based on the above, this invention proposes a control method, control device, smart stove, and storage medium for an intelligent stove. The method involves acquiring the bottom temperature of the pot from a temperature sensor; when the bottom temperature is in the rising phase, acquiring the temperature rise change time; then calculating the boiling point recognition time based on the temperature rise change time; next, determining the highest value of the bottom temperature during the temperature rise phase as the boiling point temperature, and starting to record the first duration of the boiling point temperature; when the first duration is greater than or equal to the boiling point recognition time, determining the cooking state of the pot as boiling, and controlling the current heat of the stove to decrease. According to the solution provided by this invention, the boiling state can be identified more accurately and reliably, making the control more precise. Furthermore, after determining the boiling state, automatic heat control can be achieved, reducing the possibility of food overflow and ensuring the safe and reliable operation of the stove. Simultaneously, it eliminates the need for the user to continuously observe the entire cooking process, effectively improving the intelligence level of the stove and greatly enhancing the user experience.

[0047] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0048] The stove in this embodiment of the invention is typically used with matching cookware. The cookware needs to be placed on the stove during cooking. The stove is equipped with a temperature sensor for detecting the temperature of the bottom of the cookware. The temperature sensor can be located on the burner head of the stove, thus enabling the detection of the bottom temperature of the cookware. It should be noted that the stove can be a gas stove, coal gas stove, LPG stove, induction cooker, or other cooking appliances.

[0049] The stove based on the above embodiments, such as Figure 1 As shown, an embodiment of the first aspect of the present invention provides a control method for an intelligent stove, including but not limited to steps S110 to S150:

[0050] Step S110: Obtain the bottom temperature of the pot from the temperature sensor;

[0051] It should be noted that by obtaining the temperature of the bottom of the pot, the temperature of the food can be indirectly measured, making it easier to control the cooking temperature.

[0052] Step S120: When the temperature of the bottom of the pot is in the temperature rising stage, obtain the temperature rise change time of the bottom of the pot, wherein the temperature rise change time is used to reflect the time required for the bottom of the pot to rise to a preset unit temperature.

[0053] It should be noted that when users use a stove to cook food, such as boiling water, cooking rice, making porridge, or making soup, the stove is often required to heat the food. When the stove is turned on, it will continuously heat the food in the pot, causing the temperature of the bottom of the pot to rise continuously. When the temperature of the bottom of the pot is in the rising phase, the time required for the bottom of the pot to rise to a preset unit temperature is obtained during the rising phase, that is, the temperature change time of the bottom of the pot is obtained. Specifically, during the rising phase, the temperature change time of the bottom of the pot rising by 1 degree is calculated.

[0054] Step S130: Calculate the boiling point identification time based on the temperature rise change time;

[0055] Boiling point identification time is used to determine the moment of boiling, which facilitates subsequent identification of the boiling state.

[0056] Step S140: Determine the highest value of the pot bottom temperature during the temperature rise phase as the boiling point temperature, and start recording the first duration of the boiling point temperature.

[0057] It is understandable that when the stove is turned on, the temperature of the bottom of the pot will continue to rise. When the temperature of the bottom of the pot reaches the boiling point, it will remain at that boiling point. By obtaining the highest value of the bottom temperature during the temperature rise phase, the boiling point temperature can be determined, and the first duration of the boiling point temperature can be recorded. This first duration can be understood as the duration for which the bottom temperature of the pot remains at the boiling point temperature.

[0058] Step S150: When the first duration is greater than or equal to the boiling point recognition time, the cooking state of the pot is determined to be boiling, and the current heat of the stove is reduced.

[0059] Because temperature sensors may be affected by flame and environmental interference when detecting the temperature of the pot bottom, leading to inaccurate temperature readings, recording the first duration of the boiling point temperature and determining the cooking state as boiling when this first duration is greater than or equal to the boiling point recognition time allows for accurate and reliable identification of the boiling state. In other words, when the first duration equals the boiling point recognition time, the current moment can be considered the boiling point. Furthermore, after determining the boiling state, reducing the current heat of the stove can reduce the risk of overflow. For example, when boiling water, making soup, or cooking porridge, the heat can be reduced promptly after the water boils to prevent water from overflowing onto the stove, effectively ensuring the safe and reliable operation of the stove.

[0060] The control method for the intelligent stove provided in the first aspect embodiment above can realize real-time detection of the temperature of the food being cooked in the pot by acquiring the bottom temperature of the pot from a temperature sensor. When the bottom temperature of the pot is in the temperature rising stage, the time required for the bottom temperature of the pot to rise to a preset unit temperature is acquired, that is, the temperature rise change time of the bottom temperature is acquired, and the boiling point recognition time is calculated based on the temperature rise change time. Then, the highest value of the bottom temperature of the pot in the temperature rising stage is determined as the boiling point temperature, and the first duration of the boiling point temperature is recorded. When the first duration is greater than or equal to the boiling point recognition time, it means that the bottom temperature of the pot has maintained the boiling point temperature for a certain period of time, and the cooking state of the pot is determined to be boiling. This can reduce the influence of external interference and can more accurately and reliably identify the boiling state, making the control more precise. In addition, using only a temperature sensor to detect the bottom temperature of the pot can greatly reduce costs. Furthermore, after determining the boiling state, the current firepower of the stove is reduced, which can achieve the effect of automatic fire control, reduce the occurrence of food overflow, ensure the safety and reliability of the stove's operation, and eliminate the need for the user to continuously observe the entire cooking process. This can effectively improve the intelligence level of the stove and greatly improve the user experience.

[0061] In one embodiment, when a boiling state is detected, the current heat of the stove can be automatically switched to medium or low heat, or the current heat of the stove can be controlled to cycle between medium and low heat. For example, the current heat of the stove can be controlled to maintain medium heat for 10 seconds, and then the current heat of the stove can be controlled to maintain low heat for 20 seconds.

[0062] In the above-mentioned control method for intelligent cooktops, step S130, which calculates the boiling point recognition time based on the temperature rise change time, includes the following steps:

[0063] Multiply the temperature rise change time by the first preset value and add the second preset value to obtain the boiling point recognition time.

[0064] In this embodiment, the boiling point identification time can be calculated by multiplying the temperature rise change time by a first preset value and adding a second preset value. It can be understood that the boiling point identification time is used to determine the moment of boiling. By setting the first preset value and the second preset value, the influence of external interference can be effectively reduced. When the first duration is greater than or equal to the boiling point identification time, it means that the temperature at the bottom of the pot has been stabilized at the boiling point for a certain period of time, which is beneficial to improving the accuracy and reliability of identifying the boiling state.

[0065] In one embodiment, the boiling point recognition time can be expressed by the following formula:

[0066] t1 = (K*tp + t0);

[0067] Where t1 represents the boiling point recognition time; K represents the first preset value; tp represents the temperature rise change time; and t0 represents the second preset value.

[0068] Specifically, the first preset value and the second preset value can be set according to actual needs. In one embodiment, the first preset value is 4 and the second preset value is 25s.

[0069] In the above-mentioned control method for intelligent cooktops, after determining in step S150 that the cooking state of the pot is boiling and reducing the current heat of the cooktop, the control method further includes the following steps:

[0070] When the temperature of the pot bottom is higher than the first preset temperature and continues for a first preset time, the stove is turned off. The first preset temperature is obtained by adding a third preset value to the boiling point temperature.

[0071] In one embodiment, after determining that the cooking state of the pot is boiling, and controlling the current heat of the stove to decrease, since the stove continues to heat the food in the pot, dry burning may occur. For example, when boiling water, if the water continues to be heated after boiling, the water may be boiled dry. At this time, the temperature of the bottom of the pot may continue to rise. If the temperature of the bottom of the pot is greater than the first preset temperature and lasts for a first preset time, that is, the temperature of the bottom of the pot is greater than the sum of the boiling point temperature and the third preset value and has lasted for a period of time, it can be considered that dry burning has occurred, and the stove is controlled to turn off, that is, to stop continuing to heat. This can effectively ensure the safety and reliability of the stove's operation and help improve the service life of the stove.

[0072] In one embodiment, the first preset temperature can be expressed by the following formula:

[0073] Temperature (Ttemperature) = Boiling Point (Tboiling point) + Temperature (T0)

[0074] Where Ttemperature represents the first preset temperature; Tboiling point represents the boiling point temperature; and T0 represents the third preset value.

[0075] In one embodiment, the third preset value is 30 degrees and the first preset time is 3 seconds.

[0076] In the control method of the above-mentioned intelligent stove, the stove is also equipped with a proportional valve, and the control method also includes the following steps:

[0077] Increase the opening of the proportional valve to increase the current firepower of the stove;

[0078] Alternatively, the opening of the proportional valve can be reduced to decrease the current firepower of the stove.

[0079] In this embodiment, when it is necessary to control the current firepower of the stove, it can be achieved by controlling the opening of the proportional valve. If it is necessary to increase the current firepower of the stove, the opening of the proportional valve can be increased; if it is necessary to decrease the current firepower of the stove, the opening of the proportional valve can be decreased. By controlling the opening of the proportional valve, the firepower can be effectively adjusted, which can improve the reliability of the control.

[0080] In one embodiment, the opening degree of the proportional valve can be controlled by controlling the current of the proportional valve, thereby realizing the adjustment of the current firepower of the stove.

[0081] like Figure 2 As shown, the control method for the above-mentioned intelligent stove also includes, but is not limited to, steps S210 and S220:

[0082] Step S210: Obtain the current cooking recipe, wherein the cooking recipe includes at least one target temperature change curve, the target temperature change curve being used to reflect the correspondence between the target temperature at the bottom of the pot and time;

[0083] Step S220: Control the current heat of the stove according to the temperature of the bottom of the pot, so that the current temperature change curve of the bottom of the pot over time tracks the target temperature change curve corresponding to the cooking recipe.

[0084] It's important to note that in the context of the pre-cooked food industry, ingredients and seasonings are prepared in advance. Since the ingredients and seasonings are in standard quantities, the flavor can be pre-mixed. Traditional stoves typically control the heat and cooking time manually, controlling the heat to regulate the food's temperature. However, for those who don't know how to cook, even with pre-mixed flavors, it's difficult to effectively control the temperature and cooking time, thus hindering the preservation of good taste.

[0085] In this embodiment, by acquiring the current cooking recipe, which pre-stores at least one target temperature change curve, the cooking recipe guides the cooking process of the food corresponding to the recipe. The target temperature change curve reflects the correspondence between the target temperature at the bottom of the pot and time. It can be understood that the target temperature change curve is the ideal change curve of the pot bottom temperature over time during the cooking process. During the cooking process, by detecting the pot bottom temperature in real time, the target temperature in the target temperature change curve is used as the control target. The current heat of the stove is controlled according to the pot bottom temperature, so that the current temperature change curve of the pot bottom over time tracks the target temperature change curve corresponding to the cooking recipe. This means that the current temperature change curve can restore the target temperature change curve, which can effectively solve the two cooking difficulties of temperature and time, thereby effectively ensuring the good taste of the cooked food, improving the user experience, and greatly enhancing the intelligence of the stove.

[0086] It should be noted that different cooking recipes can correspond to different cooking modes, such as stir-frying, braising, pan-frying, deep-frying, etc.

[0087] In one embodiment, a fuzzy control algorithm or a proportional-integral-derivative (PID) control algorithm can be used to track the target temperature change curve, thereby enabling a better reconstruction of the target temperature change curve.

[0088] like Figure 3 As shown, in the above-mentioned control method for intelligent cooktops, the cooking recipes include multiple target temperature change curves corresponding to different cookware types, and the control method also includes, but is not limited to, steps S310 and S320:

[0089] Step S310: During the process of tracking the current target temperature change curve with the current temperature change curve, when the first difference between the bottom temperature of the pot and the target temperature is greater than the preset difference, it is determined that the pot type has changed, and the target temperature change curve corresponding to the current pot type is re-determined. The preset difference is obtained by multiplying the bottom temperature of the pot by the fourth preset value.

[0090] Step S320: Control the current temperature change curve to track the redefined target temperature change curve.

[0091] In this embodiment, during the process of the current temperature change curve tracking the current target temperature change curve, the current temperature change curve is generally similar to the target temperature change curve and almost overlaps. The temperature of the bottom of the pot is not much different from the target temperature. However, when the first difference between the bottom of the pot temperature and the target temperature is greater than a preset difference, it can be determined that the type of cookware has changed, possibly because the user has used other cookware for cooking. Then, a new target temperature change curve corresponding to the current cookware type is determined. That is, the target temperature change curve can be automatically switched to the target temperature change curve that matches the current cookware type, and temperature tracking control is performed according to the newly determined target temperature change curve, so that the current temperature change curve tracks the newly determined target temperature change curve. By continuously comparing the bottom of the pot temperature and the target temperature, it is possible to determine in time whether the type of cookware has changed, and match a suitable target temperature change curve when the type of cookware changes. This enables the cookware to adapt automatically, which helps to improve the intelligence of the stove and greatly improves the user experience.

[0092] It should be noted that the first difference can be understood as the absolute value of the difference between the bottom temperature of the pot and the target temperature, which can better determine the difference between the bottom temperature of the pot and the target temperature.

[0093] It should be noted that cookware can include, but is not limited to, iron pots, stainless steel pots, and earthenware pots.

[0094] In one embodiment, during the process of tracking the target temperature change curve from the current temperature change curve, if the first difference between the pot bottom temperature and the target temperature exceeds a preset fault value, it is considered that tracking the target temperature change curve cannot be achieved. In this case, the stove can be shut down and an abnormal fault signal can be output to ensure the reliability of the stove's operation and to remind the user to troubleshoot the problem. The preset fault value is greater than the preset difference.

[0095] In the control method of the above-mentioned smart stove, the cooking recipe also includes multiple cooking steps, each with a preset target cooking time. The control method also includes the following steps:

[0096] Obtain the continuous running time of the cooktop during the current cooking step;

[0097] When the continuous running time is greater than or equal to the target cooking time, the next cooking step is triggered and the corresponding cooking step operation prompt information is output.

[0098] Alternatively, when the real-time area is greater than or equal to the preset trigger area, the next cooking step is triggered and the corresponding cooking step operation prompt information is output. The real-time area is obtained by multiplying the second difference between the bottom temperature of the pot and the ambient temperature by the continuous running time.

[0099] In this embodiment, the cooking recipe also includes multiple cooking steps. It is understood that following these steps ensures a good taste for the cooked food. When currently in a cooking step, it is necessary to estimate the remaining cooking time to better control the cooking time. Specifically, the continuous running time of the stove in the current cooking step can be obtained first. If the current temperature change curve largely overlaps with the target temperature change curve, and the continuous running time is greater than or equal to the target cooking time, the next cooking step can be triggered, and the corresponding operation prompt information can be output. This triggering method can be understood as time-triggered; when the cooking time is up, the next cooking step can be executed, which can effectively control the cooking time rhythm and output operation prompt information. Alternatively, if the current temperature change curve does not largely overlap with the target temperature change curve, then... The system acquires the ambient temperature, then subtracts the ambient temperature from the pot bottom temperature, multiplies this difference by the continuous running time to obtain the real-time area. When the real-time area is greater than or equal to the preset trigger area, the next cooking step is triggered, and corresponding operation prompts are output. This triggering method can be understood as area triggering, which can effectively improve the control precision of cooking time. It should be noted that the operation prompts are used to remind the user to perform necessary cooking actions, such as reminding the user to add main ingredients, add auxiliary ingredients, stir-fry, etc., which can effectively improve the interactivity between the stove and the user. In addition, after triggering the next cooking step, the current heat of the stove can be automatically controlled, which is conducive to achieving the effect of intelligent cooking.

[0100] In one embodiment, the real-time area can be expressed by the following formula:

[0101] S = (T1 - T2) * t2;

[0102] Where S represents the real-time area; T1 represents the pot bottom temperature; T2 represents the ambient temperature; and t2 represents the continuous running time of the stove in the current cooking step.

[0103] like Figure 4 As shown, a second aspect of the present invention provides an operation control device 400, including a memory 410, a processor 420, and a computer program stored in the memory 410 and executable on the processor 420; the processor 420 and the memory 410 can be connected via a bus or other means. Figure 4 The example shown is connected via a bus. The processor 420 executes the computer program described above to implement the control method of the first aspect embodiment as described above, for example, performing the above-described... Figure 1 Method steps S110 to S150 in the text Figure 2 Method steps S210 and S220 in the text Figure 3 Method steps S310 and S320.

[0104] The operation control device 400 provided in this embodiment of the invention can detect the temperature of food being cooked in the pot in real time by acquiring the bottom temperature of the pot from a temperature sensor. When the bottom temperature of the pot is in the temperature rising stage, the device acquires the time required for the bottom temperature to rise to a preset unit temperature, i.e., the temperature rise change time of the bottom temperature, and calculates the boiling point recognition time based on the temperature rise change time. Then, the highest value of the bottom temperature during the temperature rising stage is determined as the boiling point temperature, and the first duration of the boiling point temperature is recorded. When the first duration is greater than or equal to the boiling point recognition time, it indicates that the bottom temperature of the pot has maintained the boiling point temperature for a certain period of time, and the cooking state of the pot is determined to be boiling. This reduces the influence of external interference and can more accurately and reliably identify the boiling state, making the control more precise. In addition, using only a temperature sensor to detect the bottom temperature of the pot can greatly reduce costs. Furthermore, after determining the boiling state, the device controls the current firepower of the stove to decrease, which can achieve the effect of automatic fire control, reduce the occurrence of food overflow, ensure the safety and reliability of the stove's operation, and eliminate the need for the user to continuously observe the entire cooking process, effectively improving the intelligence of the stove and greatly enhancing the user experience.

[0105] A third aspect of the present invention provides an intelligent stove, including the operation control device as described in the second aspect of the present invention.

[0106] The intelligent cooktop provided in this invention can detect the temperature of food being cooked in the cookware in real time by acquiring the bottom temperature of the pot from a temperature sensor. When the bottom temperature of the pot is in the temperature rising phase, the time required for the bottom temperature to rise to a preset unit temperature is acquired, i.e., the temperature rise change time of the bottom temperature is acquired. The boiling point recognition time is calculated based on the temperature rise change time, and then the highest value of the bottom temperature during the temperature rising phase is determined as the boiling point temperature. At the same time, the first duration of the boiling point temperature is recorded. When the first duration is greater than or equal to the boiling point recognition time, it indicates that the bottom temperature of the pot has maintained the boiling point temperature for a certain period of time, and the cooking state of the cookware is determined to be boiling. This can reduce the influence of external interference and can more accurately and reliably identify the boiling state, making the control more precise. In addition, using only a temperature sensor to detect the bottom temperature of the pot can greatly reduce costs. Furthermore, after determining the boiling state, the current firepower of the cooktop is reduced, which can achieve the effect of automatic fire control, reduce the occurrence of food overflow, ensure the safety and reliability of the cooktop's operation, and eliminate the need for the user to continuously observe the entire cooking process. This can effectively improve the intelligence level of the cooktop and greatly enhance the user experience.

[0107] A fourth aspect of the present invention provides a computer-readable storage medium storing computer-executable instructions that can be used to cause a computer to perform the control method of the first aspect embodiment described above, for example, to perform the above-described... Figure 1 Method steps S110 to S150 in the text Figure 2 Method steps S210 and S220 in the text Figure 3 Method steps S310 and S320. By acquiring the bottom temperature of the pot from a temperature sensor, the temperature of the food being cooked in the pot can be monitored in real time. When the bottom temperature is rising, the time required for the bottom temperature to rise to a preset unit temperature is obtained, i.e., the temperature rise change time of the bottom temperature. The boiling point recognition time is calculated based on the temperature rise change time. Then, the highest value of the bottom temperature during the temperature rise phase is determined as the boiling point temperature. At the same time, the first duration of the boiling point temperature is recorded. When the first duration is greater than or equal to the boiling point recognition time, it means that the bottom temperature has maintained the boiling point temperature for a certain period of time, and the cooking state of the pot is determined to be boiling. This reduces the influence of external interference and can more accurately and reliably identify the boiling state, making the control more precise. In addition, using only a temperature sensor to detect the bottom temperature of the pot can greatly reduce costs. Furthermore, after determining the boiling state, the current heat of the stove is reduced, which can achieve an automatic flame control effect, reducing the possibility of food overflowing and ensuring the safe and reliable operation of the stove. At the same time, the user does not need to continuously observe the entire cooking process, which can effectively improve the intelligence of the stove and greatly improve the user experience.
