[0002] Most traditional electromagnetic induction cooker control methods adopt simple power regulation and temperature control, lacking precise management of the complex interaction relationships between multiple heating zones. In actual use, due to problems such as uneven heating and unreasonable power distribution between different heating zones, it often leads to problems such as increased energy consumption, poor cooking effect, and shortened equipment lifespan. In addition, traditional electromagnetic induction cooker control methods usually rely on fixed preset parameters and lack adaptability to different cooking scenarios and cookware types, thus limiting the flexibility and intelligence level of the electromagnetic induction cooker.

The control method includes: the control device detects whether the current heating power of the resonant heating module is less than or equal to a pre-determined heating power threshold; when it is detected that the current heating power of the resonant heating module is less than or equal to the pre-determined heating power threshold, the control device sends a first sampling instruction to the current sampling module; the control device obtains the first sampling information; the control device determines whether the current working current of the resonant heating module is less than or equal to a pre-determined first working current threshold according to the first sampling information; when it is determined that the current working current is less than or equal to the first working current threshold, the control device sends a power-off signal to the drive circuit.

[0004] The prior art completes the control of the electromagnetic induction cooker by processing the current threshold. However, when different users use the electromagnetic induction cooker, it cannot be adjusted according to the heating zones existing on the electromagnetic induction cooker, resulting in the electromagnetic induction cooker not being able to be adjusted according to the user's accustomed method during operation, and easily causing the problem of increased energy consumption.

[0030] Embodiments of the present invention will be described in detail below. The embodiments described below are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention. For those without specific technologies or conditions noted in the embodiments, they shall be carried out according to the technologies or conditions described in the literature in the field or according to the product specifications.

[0031] Referring to Figure 1 , a full-automatic control method for an induction cooker, comprising: S1, obtaining multiple heating areas on the induction cooker, initializing each heating area, and determining the initial heating power of the corresponding heating area within each working cycle.

[0032] As Figure 2 shown, the processing method for initializing the heating area in step S1 includes: S11, obtaining the cookware detection situation, cooking weight, and cooking parameters; according to the cookware detection situation, cooking weight, and cooking parameters, performing an initial setting on the heating area to obtain the initial heating power.

[0033] For the cookware detection situation, it includes using a cookware detector to determine whether there is a cookware currently and determining the load value when the cookware is placed. When the load value exceeds a preset threshold, it is determined that there is a cookware placed on the heating area.

[0034] The cookware detector at this time is a coil set for detecting the presence of the cookware, and it determines whether there is a cookware at this time according to the load change detected by the coil after the cookware is placed; for example, when there is no cookware, the inductance of the cookware detector is L0, and when there is a load with a cookware, it is L1. When the change value of the inductance value at this time is greater than the preset threshold, it is considered that there is a cookware placed.

[0035] When there is a cookware placed on the heating area, record the inductance change data on the heating area, extract the peak value, average value, and variance of the inductance change; input the inductance change data into the classification model to obtain the cookware type on the heating area.

[0036] When comparing the inductance change data with the classification model, use the peak value, average value, and variance of the inductance change as the retrieval conditions, and use the corresponding cookware type in the classification model as the content to be retrieved, and perform retrieval in sequence. When retrieving, use the cookware type output by training with the SVM model at this time, so as to obtain the current required output result.

[0037] Finally, obtain the area of the region corresponding to the inductance change data to obtain the size of the cookware; at this time, divide the heating area into multiple small grid areas, determine whether the inductance change value in each grid area is greater than the preset threshold, and calculate the total area of the grid areas greater than the preset threshold, so as to obtain the corresponding cookware size.

[0038] Among them, Diameter represents the size of the cookware, π represents pi, and Area represents the total area of the grid region where the inductance change value is greater than the preset threshold.

[0039] Take the recognized cookware type, cookware size, and the result of whether there is a cookware as the cookware detection situation.

[0040] For the recognition method of the cooking weight, a weight sensor is set on the heating area to obtain the cooking weight at this time.

[0041] The cooking parameters are represented as the working temperature, working power, and working time of the induction cooker; these cooking parameters can be explained by the following description.

[0042] The above-mentioned working temperature represents the temperature value and the corresponding temperature range that are often set for the induction cooker.

[0043] The working power represents the power levels that are often set, and records the occurrence times and the front-back distribution of these power levels.

[0044] The working time represents the working time of the induction cooker at the corresponding temperature, power, and mode during cooking, and records the total usage time frequency of the induction cooker to determine whether the working time is normal at this time.

[0045] Based on the parameters obtained above, some common parameters of the induction cooker during operation can be known, and according to the clustering situation of these parameters, the preference settings at this time can be determined. At the same time, the changes in these parameters can reflect the changes in the current cooking requirements, and can monitor whether the corresponding controls of the user during the use of the induction cooker are normal; these obtained parameters can represent the user's behavior habits during the use of the induction cooker, so as to adjust the initial heating power of the induction cooker to meet the user's needs for different situations.

[0046] S12. Standardize the cookware detection situation, cooking weight, and cooking parameters. According to the cookware detection situation, cooking weight, and cooking parameters, set classification identifiers for the heating area, and determine the attribute feature information corresponding to the heating area. The attribute feature information is represented as parameters such as cookware type, size, and cooking weight. These parameters are components of the cookware detection situation, cooking weight, and cooking parameters, and are described separately in the above content.

[0047] S13. Obtain the heating feature library. The heating feature library contains the historical feature information corresponding to the heating area and the preset heating power, and is used for comparative analysis of the attribute feature information; at the same time, the historical feature information in the heating feature library will be pre-allocated categories and the corresponding preset heating power will be noted, so that the heating power can be set according to the matching recognition method.

[0048] S14. Calculate the attribute similarity between the attribute feature information and the heating feature library, and retrieve the set of attribute features within the preset threshold based on the attribute similarity.

[0049] S15. Conduct an adjustment analysis on the set of attribute features to determine the initial heating power for the corresponding heating area in each working cycle.

[0050] When calculating the attribute similarity between the attribute feature information and the heating feature library, two types of data are used as inputs. The Pearson correlation coefficient is used to compare each value in the attribute feature information and the heating feature library with the corresponding average values of the attribute feature information and the heating feature library, thereby obtaining the attribute similarity at this time. Then, based on the value of the attribute similarity, the set of data composed of the current attribute feature information and the heating feature library is retrieved. When the attribute similarity is greater than the preset threshold, it indicates that the attribute feature information is classified into a category in the form of the heating feature library at this time, and the corresponding preset heating power is obtained. At the same time, the heating power will be adjusted according to the current set of attribute features, thereby obtaining the initial heating power that meets the current user's habits.

[0051] At the same time, the set of attribute features will internally contain the preset heating power of the heating feature library, as well as data corresponding to the cookware detection situation, cooking weight, and cooking parameters, such as parameters like working time and cooking weight. At this time, when the attribute similarity is greater than 0.6, the set of attribute features will be combined with the preset heating power in the heating feature library to obtain the set of attribute features.

[0052] Such as Figure 3 As shown, the implementation method of conducting an adjustment analysis on the set of attribute features in step S15 is as follows: S151. Conduct a matching analysis on the set of attribute features to determine the feature matching degree of the set of attribute features.

[0053] S152. According to the feature matching degree of the set of attribute features, calculate the error factor of the set of attribute features within the value range of the cookware detection situation, cooking weight, and cooking parameters, and determine the error adjustment amount of the set of attribute features.

[0054] S153. Obtain the initial heating power based on the error factor and error adjustment amount of the set of attribute features.

[0055] For the calculated feature matching degree mentioned above, it means extracting the preset heating power, working time, and cooking weight from the set of attribute features to obtain the feature matching degree at this time. The specific manifestation is as follows.

[0056] Among them, FMD represents the feature matching degree, p cur represents the current preset heating power, t cur represents the current working time, w curRepresents the current cooking weight, p opt Represents the optimal preset heating power, t opt Represents the optimal working time, w opt Represents the optimal cooking weight; the optimal preset heating power, optimal working time, and optimal cooking weight set at this time can be pre-annotated with historical data, so that the feature matching degree of the corresponding parameters at this time can be selected.

[0057] The error factor mentioned above is expressed as the standard deviation of the current cookware detection situation, cooking weight, cooking parameters and historical data, and the error adjustment amount is the difference between the error factor and the average value of the historical data.

[0058] Then the initial heating power at this time can be expressed as follows.

[0059] At this time, p adj Represents the initial heating power, p cur Represents the current preset heating power, ε pot Represents the error factor of the cookware detection situation, ε weight Represents the error factor of the cooking weight, ε param Represents the error factor of the cooking parameters, δ pot Represents the error adjustment amount of the cookware detection situation, δ weight Represents the error adjustment amount of the cooking weight, δ param Represents the error adjustment amount of the cooking parameters.

[0060] S2. Record the working conditions of each heating area, and determine the change curves of the current and voltage of each heating area during heating.

[0061] At this time, the initially set heating power will be identified, and the current and voltage values of the heating area under the initial heating power will be determined, so as to determine whether there will be relatively abnormal changes in the current and voltage at this time, and whether the output power of the heating area will be affected under this change, resulting in overall heating loss.

[0062] S3. Determine the heating distribution factor according to the change curves of the voltage and current of each heating area; determine the heating distribution loss between each heating area according to the obtained heating distribution factor.

[0063] S4. Verify the load response solution when each heating area works together, and obtain the power loss factor corresponding to the heating area.

[0064] S5. Determine the loss evaluation result of the induction cooker during use according to the power loss factor and heating distribution loss of the heating area.

[0065] When calculating the heating distribution loss in step S3, the heating area is regarded as a multiplication area, and the processing method of each multiplication area will be adjusted according to different habits. At this time, the adjusted content is included in one or more of the factors used above to complete the joint control of different heating areas and improve the control effect of the induction cooker.

[0066] Therefore, when determining the heating distribution numerator and the heating distribution loss, it is necessary to determine the specific working conditions of the induction cooker at this time, such as steaming, stir-frying, or other selected working conditions, and set the time period of each temperature and power combination during the working process as a working cycle to determine the loss situation of the heating distribution within the working cycle; this loss situation of the heating distribution is more inclined to calculate the energy loss due to different heating powers between regions during multi-region heating or due to uneven distribution at this time. For example, when the induction cooker in use has two or more heating areas and each heating area can be set independently, if the stir-frying setting is carried out on one side while the slow-simmering mode is used on the other side, there may be a problem with the heating power distribution on both sides, resulting in a deviation between the actual output power and the preset power and causing a loss in heating distribution.

[0067] Such as Figure 4 As shown, the implementation method of step S3 also includes the following implementation methods.

[0068] S31, Obtain the voltage and current of each heating area within each working cycle, and determine the working mode corresponding to the heating area in each cycle.

[0069] S32, Determine the target power according to the working mode corresponding to the heating area in each cycle and the initial heating power.

[0070] S33, Calculate the instantaneous power of each heating area, and determine the heating distribution factor of each heating area according to the working mode and the instantaneous power.

[0071] S34, Compare the heating distribution factors within all working cycles with the target power to obtain the heating distribution loss.

[0072] When determining the above-mentioned working mode, obtain the heating time, heating frequency, and average heating power of the corresponding working cycle; according to the heating frequency, heating time, and average heating power, obtain the working mode corresponding to the heating area; working modes such as rapid heating mode, slow-simmering mode, heat preservation mode, etc. will have different values in terms of heating frequency, heating time, and average heating power. At this time, the corresponding working mode can be selected according to these three numbers.

[0073] The above target power is adjusted according to the working mode and the initial heating power when selected. For example, if it is determined that the current is in the "boiling mode" and the initial heating power is 1200W, and according to the requirements of the boiling mode, the target power is 1500W, then at this time, it is necessary to make the final reach the target power according to the heating situation at this time, and this target power will be set with the corresponding value in the database according to the corresponding working mode.

[0074] As Figure 5 shown, the implementation method of obtaining the target power in step S32 further includes: S321, determining the heating time advance according to the working mode, and obtaining the target heating moment according to the heating time advance and the heating time.

[0075] S322, obtaining the temperature difference between the initial temperature at the target heating moment and the temperature corresponding to the working mode to obtain the preheating power.

[0076] S323, heating the heating area according to the preheating power, and when receiving the working mode switching instruction, heating at a preset step size and time interval until the target power is reached.

[0077] Different working modes may have different heating time advances; the heating time advance refers to the time difference required from the start of heating to actually reaching the target temperature; for example, in the fast heating mode: the advance may be 1 - 2 minutes; in the slow cooking mode: the advance may be 5 - 10 minutes.

[0078] The above target heating time is the sum of the current time and the heating time advance; for the preheating power, it can be determined according to the following method, such as preheating power = (temperature difference × heating mass × specific heat capacity) / (heating time advance × heating efficiency); to obtain the selected preheating power at this time. The preset step size and time interval will be set according to the heating requirements. Assuming that the target power is 1500W at this time, the preset step size is 100W, and the time interval is 10 seconds; gradually increasing from the current power to 1500W; the selected preset step size at this time is this 100W, which is used to preheat the induction cooker in advance.

[0079] The heating distribution factor in step S33 is obtained by calculating the average value of the instantaneous power of the current heating area during the corresponding working cycle of the current heating area, and then taking the ratio of this average value to the total power of all heating areas as the heating distribution factor at this time; the instantaneous power at this time is calculated from the measured current and voltage on the corresponding heating area.

[0080] The heating distribution loss is expressed in the following way at this time.

[0081] Among them, HAL represents the heating distribution loss, HAF iThe heating distribution factor of the \(i\)-th heating area, \(HAF'\) represents the standard value of the heating distribution factor, \(p\) total represents the total power of all heating areas, \(n\) represents the number of heating areas, and the value range of \(i\) is from 1 to \(n\); the standard value of the heating distribution factor is expressed as the ratio of the target power of the corresponding heating area in the working mode to the total power of all heating areas, and is used to determine whether there are corresponding losses when heating multiple areas at this time.

[0082] In step S4, the load response solution is obtained by simulating the load change, observing the power change of each heating area, and calculating the response time and response amplitude after the load change, so as to obtain the load response solution at this time, and according to the value of the load response solution at this time, the value of the power loss factor under the corresponding load change is obtained.

[0083] The response time at this time refers to the time required for the heating area to adjust the heating power from detecting the load change, and the response amplitude represents the difference between the average values of the heating powers of the corresponding heating area before and after the load change.

[0084] The above-mentioned load change can be illustrated by the following example.

[0085] Suppose there are three heating areas A, B, and C on the induction cooker, and they are all working together to complete a cooking task.

[0086] Initial state: A frying pan is placed on area A and is executing the fast heating mode; a soup pot is placed on area B and is executing the slow cooking mode; there is no pot on area C and it is in the standby state.

[0087] Load change: The user moves the frying pan from area A to area C; area A detects the disappearance of the load and stops heating; area C detects the new load and adjusts the heating power according to the new load; area B continues to execute the slow cooking mode, but since area C starts to heat, it may be disturbed and needs to adjust the heating power to maintain a constant temperature.

[0088] Then the load response solution can be expressed as follows. Obtain the response time and response amplitude of each heating area before and after the load change to obtain the load response solution. At this time, the load response solution can be expressed as \(f(τ\) i ,Δpva i ), where \(τ\) i represents the response time of the \(i\)-th heating area, \(Δpva\) i represents the response amplitude of the \(i\)-th heating area.

[0089] \(f(τ\) i ,Δpva i )=α·τ i +β·Δpvai where α represents the adjustment coefficient of the response time, and β represents the adjustment coefficient of the response amplitude; at this time, both the response time and the response amplitude are normalized during calculation to remove the dimension of the corresponding data.

[0090] At this time, the adjustment coefficients of the response time and the response amplitude can be set to 1 and 0.5 in sequence to complete the solution of the current response time and response amplitude.

[0091] At this time, the power loss factor corresponding to the heating area can be expressed as follows. Obtain the response amplitude and response time in the load response solution to obtain the power loss factor.

[0092] where η i represents the power loss factor of the i-th heating area, τ i represents the response time of the i-th heating area, Δpva i represents the response amplitude of the i-th heating area, p rate,i represents the rated power of the i-th heating area, τ load represents the total time of load change, and e represents the exponential constant; at this time, the power loss factor corresponding to each heating area can be obtained.

[0093] Then the loss evaluation result in step S5 can be expressed in the following form.

[0094] where LSR represents the loss evaluation result, η i represents the power loss factor of the i-th heating area, p i ′ represents the average heating power of the i-th heating area, HAL represents the heating distribution loss, n represents the number of heating areas, and the value range of i is from 1 to n.

[0095] Through the obtained loss evaluation result, the working state of the current induction cooker can be detected in time, and this value can be transmitted to an external device for monitoring. When a problem is found, the state of the induction cooker can be controlled by notifying the corresponding user.

[0096] Such as Figure 6As shown, the present invention also provides a full-automatic control system for an induction cooker, including: an initialization module, a heating record module, a heating distribution module, a power loss module, and a loss evaluation module; the initialization module transmits data to the heating record module, and the heating record module records the working conditions of the heating area at the initial heating power. At this time, the working conditions obtain the change curves of current and voltage and transmit this part of the data to the heating distribution module and the power loss module. The heating distribution module determines the heating distribution loss generated at this time as the output result; the power loss module calculates the power loss factor at this time as the output result, and the loss evaluation module obtains the loss evaluation result at this time according to the output results of the heating distribution module and the power loss module, completing the state evaluation of the induction cooker.

[0097] The initialization module is used to obtain information on the pan detection situation, cooking weight, and cooking parameters; perform standardized processing on the obtained information, determine the attribute characteristic information of the heating area according to the standardized information, obtain the heating characteristic library, and calculate the similarity between the attribute characteristic information and the heating characteristic library; retrieve the set of attribute characteristics within the preset threshold based on the similarity and determine the initial heating power.

[0098] The heating record module is used to record the working conditions of each heating area, including the change curves of current and voltage.

[0099] The heating distribution module is used to obtain the voltage and current of each heating area, determine the working mode; determine the target power according to the working mode and the initial heating power; calculate the instantaneous power, and determine the heating distribution factor according to the working mode; compare the heating distribution factor with the target power to obtain the heating distribution loss.

[0100] The power loss module is used to obtain the response time and response amplitude of the heating area to obtain the power loss factor of the heating area.

[0101] The loss evaluation module is used to obtain the loss evaluation result according to the output results of the heating distribution module and the power loss module.

[0102] As Figure 7As shown, the present invention also provides an induction cooker device, including a processor 1001 and a memory 1002. The memory 1002 stores computer-readable instructions. When the computer-readable instructions are executed by the processor 1001, the steps in any one of the above-mentioned full-automatic control methods for an induction cooker are run, and the following functions can be achieved: The system can intelligently adjust the heating power according to information such as cookware detection and cooking weight to achieve precise heating; through the heating distribution factor and the power loss factor, the system can monitor the working state of the heating area in real time, and optimize the energy distribution by calculating the heating distribution loss and the power loss factor to reduce energy consumption; the system can adjust the heating power in real time to maintain the target temperature and improve the cooking quality; the system can comprehensively evaluate the energy loss during the heating process and provide a detailed energy consumption report for the user to help the user understand the energy consumption situation.
