[0002] Traditional induction cooker control methods mostly use simple power regulation and temperature control, lacking precise management of the complex interactions between multiple heating zones. In actual use, problems such as uneven heating between different heating zones and unreasonable power distribution often lead to increased energy consumption, poor cooking results, and shortened equipment life. In addition, traditional induction cooker control methods usually rely on fixed preset parameters and lack adaptability to different cooking scenarios and pot types, thus limiting the flexibility and intelligence of induction cookers.

[0003] For example, Chinese patent publication number CN112333864A discloses a control method and device for an induction cooker, the control method comprising: a control device detects whether the current heating power of the resonant heating module is less than or equal to a predetermined heating power threshold; when it is detected that the current heating power of the resonant heating module is less than or equal to the predetermined heating power threshold, the control device sends a first sampling instruction to the current sampling module; the control device obtains first sampling information; the control device determines whether the current working current of the resonant heating module is less than or equal to a predetermined first working current threshold based on 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 shutdown signal to the drive circuit.

[0004] The prior art controls the induction cooker by processing the current threshold, but when different users use the induction cooker, it cannot be adjusted according to the heating area on the induction cooker, resulting in the induction cooker being unable to be adjusted according to the user's habits when working, which easily causes the problem of increased energy consumption. Summary of the invention

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: a fully 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 in each working cycle.

[0030] The embodiments of the present invention are 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 limiting the present invention. If no specific techniques or conditions are specified in the embodiments, the techniques or conditions described in the literature in the art or the product specifications are used.

[0031] See also Figure 1 , a fully 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 in each working cycle.

[0032] like Figure 2 As shown, the processing method for initializing the heating area in step S1 includes: S11, obtaining the pot detection status, cooking weight, and cooking parameters; initializing the heating area according to the pot detection status, cooking weight, and cooking parameters to obtain the initial heating power.

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

[0034] The pot detector at this time is a coil set to detect the presence of pots, and determines whether there is a pot at this time based on the change in load detected by the coil after the pot is placed. For example, when there is no pot, the inductance of the pot detector is L0, and the load with a pot is L1. When the change in inductance value is greater than the preset threshold value at this time, it is considered that a pot is placed.

[0035] When a pot is placed on the heating area, the inductance change data on the heating area is recorded, and the peak value, average value and variance of the inductance change are extracted; the inductance change data is input into the classification model to obtain the type of pot on the heating area.

[0036] When comparing the inductance change data with the classification model, the peak, average and variance of the inductance change are used as retrieval conditions, and the corresponding pot type in the classification model is used as the search content, and the retrieval is performed in sequence. During the retrieval, the SVM model is used to train the pot type output at this time, so as to obtain the output result currently required.

[0037] Finally, the area corresponding to the inductance change data is obtained to get the size of the pot. At this time, the heating area is divided into multiple small grid areas, and it is determined whether the inductance change value in each grid area is greater than the preset threshold, and the total area of ​​the grid areas greater than the preset threshold is calculated to obtain the corresponding pot size.

[0038] Wherein, Diameter represents the size of the pot, π represents the ratio of pi, and Area represents the total area of ​​the grid area where the inductance change value is greater than the preset threshold.

[0039] The results of identifying the type of pot, the size of the pot, and whether the pot exists are used as the pot detection situation.

[0040] The cooking weight is identified by providing a weight sensor on the heating area to obtain the cooking weight at that time.

[0041] The cooking parameters are represented by 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 operating temperatures represent the temperature values ​​that the induction cooker is often set to, as well as the corresponding temperature ranges.

[0043] The operating power indicates the power levels that are frequently set, and records the number of occurrences and the distribution of these power levels.

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

[0045] Based on the parameters obtained above, we can know some commonly used parameters of the induction cooker when it is working, and determine the preference settings at this time based on the clustering of these parameters. At the same time, the changes in these parameters can reflect the changes in current cooking needs, and can monitor whether the corresponding control of the user when using the induction cooker is normal; these obtained parameters can represent the user's behavioral habits when using the induction cooker, thereby adjusting the initial heating power of the induction cooker to meet the user's needs for different situations.

[0046] S12, standardize the pot detection status, cooking weight, and cooking parameters, set classification labels for the heating areas according to the pot detection status, cooking weight, and cooking parameters, and determine the attribute characteristic information corresponding to the heating areas. The attribute characteristic information is represented by parameters such as the pot type, size, and cooking weight. These parameters are components of the pot detection status, cooking weight, and cooking parameters, which are respectively explained in the above contents.

[0047] S13, obtaining a heating feature library, which contains historical feature information and preset heating powers corresponding to the heating area, 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-assigned to categories, and the corresponding preset heating powers will be noted, so that the heating power can be set according to the matching recognition method.

[0048] S14, calculating the attribute similarity between the attribute feature information and the heating feature library, and retrieving the attribute feature set within a preset threshold based on the attribute similarity.

[0049] S15, adjusting and analyzing the attribute feature set to determine the initial heating power of the corresponding heating area in each working cycle.

[0050] When calculating the attribute similarity between the attribute feature information and the heating feature library, the two types of data are used as input, and the Peel 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, so as to obtain the attribute similarity at this time; then, according to the value of the attribute similarity, the data for comparing the current attribute feature information with the heating feature library are formed into a set and retrieved. When the attribute similarity is greater than the preset threshold, it means that the attribute feature information is classified into a category according to the form of the heating feature library, and the corresponding preset heating power is obtained. At the same time, the heating power will be adjusted according to the attribute feature set at this time, so as to obtain the initial heating power that meets the current user habits.

[0051] At the same time, the attribute feature set will include the preset heating power of the heating feature library, as well as the data corresponding to the pot detection status, cooking weight, and cooking parameters, such as working time, cooking weight and other parameters; at this time, when the attribute similarity is greater than 0.6, the attribute feature set will be combined with the preset heating power in the heating feature library to obtain the attribute feature set.

[0052] like Figure 3 As shown, the implementation method of adjusting and analyzing the attribute feature set in step S15 is as follows: S151, matching analysis is performed on the attribute feature set to determine the feature matching degree of the attribute feature set.

[0053] S152, according to the feature matching degree of the attribute feature set, calculating the error factor of the attribute feature set under the value range of the cookware detection condition, cooking weight, and cooking parameter, and determining the error adjustment amount of the attribute feature set.

[0054] S153, obtaining the initial heating power according to the error factor and error adjustment amount of the attribute feature set.

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

[0056] Among them, FMD represents the feature matching degree, p cur Indicates the current preset heating power, t cur Indicates the current working time, w curIndicates the current cooking weight, p opt represents the optimal preset heating power, t opt represents the optimal working time, w opt Indicates the optimal cooking weight; the optimal preset heating power, optimal working time, and optimal cooking weight set at this time can be pre-marked by historical data, so that the characteristic 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 condition, 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 can be expressed as shown below.

[0059] At this time, p adj represents the initial heating power, p cur Indicates the current preset heating power, ε pot The error factor representing the pot detection condition, ε weight The error factor for cooking weight, ε param Denotes the error factor of cooking parameters, δ pot Indicates the error adjustment amount of the pot detection condition, δ weight Indicates the error adjustment for cooking weight, δ param Indicates the error adjustment amount of the cooking parameters.

[0060] S2, recording the working condition of each heating area, and determining the change curve of the current and voltage of each heating area during heating.

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

[0062] S3, determining a heating distribution factor according to a variation curve of voltage and current in each heating area; and determining a heating distribution loss between each heating area according to the obtained heating distribution factor.

[0063] S4, verifying the load response solution of each heating area when working together, and obtaining the power loss factor corresponding to the heating area.

[0064] S5, determining a loss evaluation result of the induction cooker when in use according to the power loss factor of the heating area and the heating distribution loss.

[0065] In step S3, when calculating the heating distribution loss, the heating area is taken as a multiplication area, and the processing method of each multiplication area will be adjusted according to different habits. At this time, the adjustment content is included in one or more of the factors used above to complete the joint control of different heating areas to 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, frying or other selected working conditions, and set the time period of each temperature and power combination during operation as a working cycle to determine the heating distribution loss within the working cycle; this heating distribution loss situation is more inclined to calculate the energy loss caused by the different heating power in each area or the uneven distribution when heating in multiple areas. For example, when the induction cooker used has two or more heating areas, and each heating area can be set separately, if you use stir-frying on one side and slow cooking on low heat on the other side, there may be a problem of heating power distribution on both sides, resulting in a deviation between the actual output power and the preset power, causing a loss of heating distribution.

[0067] like Figure 4 As shown, the implementation of step S3 also includes the following implementation.

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

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

[0070] S33, calculating and obtaining the instantaneous power of each heating area, and determining the heating allocation factor of each heating area according to the working mode and the instantaneous power.

[0071] S34, comparing the heating allocation factors in all working cycles with the target power to obtain the heating allocation loss.

[0072] When the above-mentioned working mode is determined, the average values ​​of heating time, heating frequency and heating power of the corresponding working cycle are obtained; according to the average values ​​of heating frequency, heating time and heating power, the working mode corresponding to the heating area is obtained; working modes such as fast heating mode, slow cooking mode, insulation mode, etc., these different modes will have different values ​​in heating frequency, heating time and heating power average values. At this time, the corresponding working mode can be selected according to these three numbers.

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

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

[0076] S323, heating the heating area according to the preheating power, and when the working mode switching instruction is obtained, heating is performed according to the 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 from the start of heating to the actual reaching of the target temperature; for example, in fast heating mode: the advance may be 1-2 minutes; in slow cooking mode: the advance may be 5-10 minutes.

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

[0079] The heating distribution factor in step S33 is obtained by calculating the instantaneous power of the current heating area to obtain the average value within the corresponding working cycle of the current heating area, and then taking the ratio of the 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 by the current and voltage measured on the corresponding heating area.

[0080] The heating distribution losses are then expressed in the following way.

[0081] Where HAL represents the heating allocation loss, HAF irepresents the heating allocation factor of the ith heating zone, HAF′ represents the standard value of the heating allocation factor, and p total It represents the total power of all heating areas, n represents the number of heating areas, and i ranges 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, which is used to determine whether corresponding losses occur when heating multiple areas at this time.

[0082] The load response solution in step S4 is obtained by simulating load changes, observing the power changes in each heating area, and calculating the response time and response amplitude after the load change, and the value of the power loss factor under the corresponding load change is obtained based on the value of the load response solution at this time.

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

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

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

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

[0087] Load change: The user moves the pan from zone A to zone C; zone A detects the loss of load and stops heating; zone C detects the new load and adjusts the heating power based on the new load; zone B continues to simmer, but because zone C starts heating, it may experience some interference and needs to adjust the heating power to maintain a constant temperature.

[0088] Then the load response solution can be expressed as shown below. The response time and response amplitude of each heating area before and after the load change are obtained 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 ith heating zone, Δpva i represents the response amplitude of the i-th heating area.

[0089] f(τ i ,Δpva i )=α·τ i +β·Δpvai ; Among them, α represents the adjustment coefficient of response time, and β represents the adjustment coefficient of response amplitude; at this time, both response time and 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 response amplitude can be set to 1 and 0.5 respectively 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 shown below. The response amplitude and response time in the load response solution are obtained to obtain the power loss factor.

[0092] Among them, η i represents the power loss factor of the i-th heating zone, τ i represents the response time of the ith heating zone, Δpva i represents the response amplitude of the ith heating area, p rate,i represents the rated power of the i-th heating zone, 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 as shown in the following form.

[0094] Among them, LSR represents the loss evaluation result, η i represents the power loss factor of the ith heating zone, p i ′ represents the average heating power of the i-th heating zone, HAL represents the heating distribution loss, n represents the number of heating zones, and the value of i ranges from 1 to n.

[0095] The loss assessment result can be used to timely detect the current working status of the induction cooker, and the value can be transmitted to an external device for monitoring. When a problem is found, the status of the induction cooker can be controlled by notifying the corresponding user.

[0096] like Figure 6As shown, the present invention also provides a fully automatic control system for an induction cooker, comprising: an initialization module, a heating recording module, a heating allocation module, a power loss module, and a loss evaluation module; the initialization module transmits data to the heating recording module, and the heating recording module records the working conditions of the heating area under the initial heating power. At this time, the working conditions obtain the change curves of current and voltage and transmit this part of data to the heating allocation module and the power loss module, and the heating allocation module determines the heating allocation loss generated at this time as an output result; the power loss module calculates the power loss factor at this time as an output result, and the loss evaluation module obtains the loss evaluation result at this time according to the output results of the heating allocation module and the power loss module, and completes the status evaluation of the induction cooker.

[0097] The initialization module is used to obtain information on pot detection, cooking weight, and cooking parameters; standardize the obtained information, determine the attribute feature information of the heating area based on the standardized information, obtain the heating feature library, and calculate the similarity between the attribute feature information and the heating feature library; retrieve the attribute feature set within a preset threshold based on the similarity, and determine the initial heating power.

[0098] The heating recording 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 and 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 and obtain the power loss factor of the heating area.

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

[0102] like 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, and when the computer-readable instructions are executed by the processor 1001, the steps in any one of the above-mentioned steps of the fully automatic control method of the induction cooker are executed, and the following functions can be realized: the system can intelligently adjust the heating power according to the detection status of the pot, the cooking weight and other information to achieve precise heating; through the heating distribution factor and the power loss factor, the system can monitor the working status of the heating area in real time, and optimize the energy distribution and reduce the energy consumption by calculating the heating distribution loss and the power loss factor; the system can adjust the heating power in real time, maintain the target temperature and improve the cooking quality; the system can comprehensively evaluate the energy loss during the heating process, provide the user with a detailed energy consumption report, and help the user understand the energy consumption.
