[0022] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0023] To achieve uniform heating of cookware and improve the heating efficiency of the system, electromagnetic heating equipment can be equipped with an inner ring heating coil and an outer ring heating coil. Under different application scenarios, the inner ring heating coil and the outer ring heating coil can be controlled to perform corresponding operations to meet the user's needs.

[0024] For example, when placing large-diameter cooking pots, a double-ring heating method can be used; when placing small-diameter pots, an inner-ring heating method can be used, which can effectively improve heating efficiency and avoid energy loss.

[0025] However, in actual use, the cookware is prone to shifting, with some parts of the cookware extending beyond the heating area, resulting in uneven heating. Users may not easily notice the shift and cannot adjust the cookware in time, thus affecting the performance.

[0026] To address the aforementioned issues, the inventors have proposed the offset control method, apparatus, electromagnetic heating device, and storage medium provided in this application. This method is applied to an electromagnetic heating device equipped with an inner ring heating coil and an outer ring heating coil. The method includes: determining inner ring standard parameters and outer ring standard parameters based on heating detection parameters; determining a first offset parameter based on the inner ring detection parameters and inner ring standard parameters of the inner ring heating coil; determining a second offset parameter based on the outer ring detection parameters and outer ring standard parameters of the outer ring heating coil; determining an offset distance based on the first and second offset parameters; and executing offset control measures corresponding to the offset distance when the offset distance meets control conditions. This allows for timely determination of the cookware's offset based on changes in the inner and outer ring parameters, enabling the implementation of corresponding control measures to reduce the impact on cooking results and improve the user experience.

[0027] The following section describes the application environment of the meeting management method provided by this invention.

[0028] Please see Figure 1 , Figure 1 This is a schematic diagram illustrating an application scenario of a heating control method provided in an embodiment of the present invention, such as... Figure 1 As shown, the electromagnetic heating device 100 includes: a device body 110 and an inner ring heating coil 120 and an outer ring heating coil 130 disposed on the device body 110.

[0029] In the embodiments of this application, the electromagnetic heating device 100 can heat the cooking pot placed on the device body 110. When the cooking pot is located in the inner ring heating area A corresponding to the inner ring heating coil 120, the inner ring heating coil 120 can heat the cooking pot; when the cooking pot is located in the outer ring heating area B corresponding to the outer ring heating coil 130, the outer ring heating coil 130 can heat the cooking pot.

[0030] like Figure 2 As shown, the cooking pot 200 is placed at the center of the electromagnetic heating device 100, so that heating can be controlled by the inner ring heating coil 120 and the outer ring heating coil 130.

[0031] However, the cooking pot 200 may move during the heating process, causing a positional shift, such as... Figure 3 As shown, the cooking pot 200 deviates from the electromagnetic heating device 100 by an offset distance d. When the cooking pot 200 deviates, it will affect the heating effect. In this embodiment, the offset of the pot is determined by the changes in the inner and outer loop parameters, so as to take corresponding control measures in a timely manner to reduce the impact of the pot offset on the cooking effect. The details will be described in detail in the following embodiments.

[0032] It should be noted that, Figure 1-3These are merely exemplary application scenarios. The methods provided in this application embodiment can also be applied to other application scenarios, and no limitations are imposed here.

[0033] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0034] Please see Figure 1 This application provides an offset control method that can be applied to the aforementioned electromagnetic heating device equipped with an inner ring heating coil and an outer ring heating coil. For example... Figure 1 As shown, the method includes steps 310 to 350.

[0035] Step 310: Determine the standard parameters of the inner ring and the standard parameters of the outer ring based on the heating test parameters.

[0036] In the embodiments of this application, the heating detection parameter is a reference parameter for offset determination.

[0037] In some implementations, the heating detection parameters can be the operating parameters of the electromagnetic heating device, such as the driving frequency of the electromagnetic heating device, the total power of the electromagnetic heating device, the operating voltage of the electromagnetic heating device, and the operating current of the electromagnetic heating device.

[0038] Under the same heating detection parameters, the operating parameters of the inner and outer ring heating coils are different in the offset state and the no-offset state; in the offset state, the operating parameters of the inner and outer ring heating coils are also different for different degrees of offset.

[0039] In the embodiments of this application, when the inner ring standard parameters are in a state of no offset, the operating parameters corresponding to the heating detection parameters of the inner ring heating coil are, for example, the power of the inner ring heating coil, resonance parameters (resonance voltage, current), etc.

[0040] In the embodiments of this application, when the outer ring standard parameters are in a state of no offset, the operating parameters of the outer ring heating coil and the heating detection parameters are as follows: for example, the power and resonance parameters (resonant voltage, current) of the outer ring heating coil.

[0041] In some implementations, a mapping relationship between the heating detection parameters and the inner loop standard parameters and the outer loop standard parameters can be preset, so that the inner loop standard parameters and the outer loop standard parameters corresponding to the current heating detection parameters can be determined according to the mapping relationship.

[0042] In some embodiments, the heating detection parameter is the driving frequency of the electromagnetic heating device. The electromagnetic heating device may include a driving module connected to an inner ring heating coil and an outer ring heating coil. When the electromagnetic heating device is operating, the driving module controls the inner and outer ring heating coils to operate according to the driving frequency. Optionally, the driving frequency is a PWM (Pulse Width Modulation) frequency.

[0043] Optionally, the driving frequency is used to control the operation of the inner ring heating coil and the outer ring heating coil. That is, the inner ring heating coil and the outer ring heating coil have the same driving frequency.

[0044] Optionally, the driving frequency includes a first sub-driving frequency and a second sub-driving frequency. The first sub-driving frequency is used to control the inner ring heating coil to operate, and the second sub-driving frequency is used to control the outer ring heating coil to operate. Therefore, the inner ring heating coil and the outer ring heating coil can employ different driving frequencies.

[0045] In some implementations, the heating detection parameter is used as the driving frequency, the inner loop standard parameter is the power of the inner loop heating coil, and the outer loop standard parameter is the power of the outer loop heating coil, as an example for illustration.

[0046] Figure 5 The mapping relationship between heating detection parameters and outer ring standard parameters is shown. For example... Figure 5 As shown, in the no-offset state, with the increase of the driving frequency, the outer loop standard parameter (i.e., the power of the outer loop heating coil) decreases accordingly. For example, when the driving frequency is f1, the corresponding power of the outer loop heating coil is P1; when the driving frequency is f2, the corresponding power of the outer loop heating coil is P2; where f1 < f2, and P1 > P2.

[0047] Figure 6 The mapping relationship between heating detection parameters and inner ring standard parameters is shown. For example... Figure 6 As shown, in the no-offset state, as the heating detection parameter (driving frequency) increases, the inner loop standard parameter (i.e., the power of the inner loop heating coil) decreases accordingly. For example, when the driving frequency is f1, the corresponding power of the inner loop heating coil is P3; when the driving frequency is f2, the corresponding power of the inner loop heating coil is P4; where f1 < f2, and P3 > P4.

[0048] In some implementations, the heating detection parameter is the total power of the electromagnetic heating device. It is understood that whether the inner and outer heating coils operate simultaneously or separately, or whether their respective power levels differ, will affect the total power of the electromagnetic heating device. The higher the power of the inner and outer heating coils, the higher the total power of the electromagnetic heating device.

[0049] In some implementations, the heating detection parameter is the total power of the electromagnetic heating device, the inner loop standard parameter is the resonant current, and the outer loop standard parameter is the resonant current of the outer loop heating coil, which are used as examples for illustration.

[0050] Figure 7 The mapping relationship between heating detection parameters and outer ring standard parameters is shown. For example... Figure 7 As shown, in the state without offset, as the heating detection parameter (total power) increases, the outer loop standard parameter (i.e., the peak value of the resonant current of the outer loop heating coil) also increases. For example, when the total power is P1, the corresponding peak value of the resonant current of the outer loop heating coil is I2; when the total power is P2, the corresponding peak value of the resonant current of the outer loop heating coil is I1; where P1 < P2, and I2 > I1.

[0051] Figure 8 The mapping relationship between heating detection parameters and outer ring standard parameters is shown. For example... Figure 8 As shown, in the state without offset, as the heating detection parameter (total power) increases, the inner loop standard parameter (i.e., the peak value of the resonant current of the inner loop heating coil) also increases. For example, when the total power is P3, the corresponding peak value of the resonant current of the inner loop heating coil is I4; when the total power is P4, the corresponding peak value of the resonant current of the inner loop heating coil is I3; where P3 < P4, and I4 > I3.

[0052] It is understandable that the mapping relationship between the heating detection parameters and the inner and outer ring standard parameters can be obtained in advance through experimental testing, and the selection of the heating detection parameters and the inner and outer ring standard parameters can also be determined according to actual usage needs. This application does not impose any restrictions on this.

[0053] Step 320: Determine the first offset parameter based on the inner ring detection parameters and the inner ring standard parameters of the inner ring heating coil.

[0054] In the embodiments of this application, the inner loop detection parameters are the operating parameters obtained in real time by the inner loop heating coil. The type of the inner loop detection parameters is the same as the type of the inner loop standard parameters.

[0055] In some implementations, the inner loop detection parameter is the inner loop detection power, which is the power of the inner loop heating coil.

[0056] In other embodiments, the inner loop detection parameter is the inner loop detection resonance parameter, that is, the resonance parameter of the inner loop heating coil.

[0057] Optionally, the inner loop detection resonance parameter is the inner loop detection resonance current, that is, the resonance current of the inner loop heating coil.

[0058] Optionally, the inner loop detection resonance parameter is the inner loop detection resonance voltage, that is, the resonance voltage of the inner loop heating coil.

[0059] It is understood that other operating parameters, such as resonant frequency, can also be used for the inner loop detection parameters, and this application does not impose any restrictions on this.

[0060] In some implementations, step 320 includes the following steps.

[0061] (1) Determine the inner ring difference based on the inner ring detection parameters and the inner ring standard parameters of the inner ring heating coil.

[0062] (2) Determine the first offset parameter based on the inner loop detection parameters and the inner loop difference.

[0063] In the embodiments of this application, in the no-offset state, the inner ring detection parameter of the inner ring heating coil is equal to the inner ring standard parameter, or the difference is less than a preset threshold. In the offset state, however, there is a difference between the inner ring detection parameter and the inner ring standard parameter, or the difference is greater than or equal to the preset threshold, and the more severe the offset, the larger the difference. Therefore, the inner ring difference can be determined based on the inner ring detection parameter and the inner ring standard parameter, and a first offset parameter determined based on the inner ring detection parameter and the inner ring difference can be used as a reference for offset judgment.

[0064] In some implementations, the inner ring difference can be determined based on the inner ring detection parameters of the inner ring heating coil and the inner ring standard parameters.

[0065] Alternatively, the difference between the inner loop testing parameters and the inner loop standard parameters can be used as the inner loop difference value.

[0066] In some implementations, to further measure the offset, the ratio of the inner loop difference to the inner loop detection parameter can be used as the first offset parameter. Therefore, the larger the first offset parameter, the greater the degree of offset.

[0067] In one embodiment, the example is given with the driving frequency of the electromagnetic heating device as the heating detection parameter, the inner loop detection power as the inner loop detection parameter, and the power of the inner loop heating coil as the inner loop standard parameter.

[0068] Assuming the driving frequency of the electromagnetic heating device is fx, the standard parameter of the inner loop (i.e., the power of the inner loop heating coil in the no-offset state) is P. 内环 If the inner loop detection power is Px, then the inner loop difference is: A1 = Px.内环 -Px; The first offset parameter is: B1 = A1 / P 内环 =(P 内环 -Px) / P 内环 .

[0069] In another embodiment, the heating detection parameter is the total power of the electromagnetic heating device, the inner loop detection parameter is the inner loop detection resonant current, and the inner loop standard parameter is the resonant current of the inner loop heating coil, as an example for explanation.

[0070] Assuming the total power of the electromagnetic heating device is Px, the standard parameter of the inner loop (i.e., the resonant current of the inner loop heating coil in the no-offset state) is I. 内环 If the inner loop resonant current is Ix, then the inner loop difference is: A1 = Ix - I 内环 The first offset parameter is: B1 = A1 / I 内环 =(Ix-I 内环 ) / I 内环 .

[0071] Step 330: Determine the second offset parameter based on the outer ring detection parameters and the outer ring standard parameters of the outer ring heating coil.

[0072] In the embodiments of this application, the outer ring detection parameters are the operating parameters obtained in real time from the outer ring heating coil. The type of the outer ring detection parameters is the same as the type of the outer ring standard parameters.

[0073] In some implementations, the outer loop detection parameter is the outer loop detection power, which is the power of the outer loop heating coil.

[0074] In other embodiments, the outer loop detection parameter is the outer loop detection resonance parameter, that is, the resonance parameter of the outer loop heating coil.

[0075] Optionally, the outer ring detection resonance parameter is the outer ring detection resonance current, that is, the resonance current of the outer ring heating coil.

[0076] Optionally, the outer ring detection resonance parameter is the outer ring detection resonance voltage, that is, the resonance voltage of the outer ring heating coil.

[0077] It is understood that other operating parameters, such as resonant frequency, can also be used for the outer loop detection parameters, and this application does not impose any restrictions on this.

[0078] In some implementations, step 330 includes the following steps.

[0079] (1) Determine the outer ring difference based on the outer ring detection parameters and the outer ring standard parameters of the outer ring heating coil.

[0080] (2) Determine the second offset parameter based on the outer ring detection parameters and the outer ring difference.

[0081] In the embodiments of this application, in the no-offset state, the outer ring detection parameters of the outer ring heating coil are equal to the outer ring standard parameters, or the difference is less than a preset threshold. In the offset state, however, there is a difference between the outer ring detection parameters and the outer ring standard parameters, or the difference is greater than or equal to the preset threshold, and the more severe the offset, the larger the difference. Therefore, the outer ring difference can be determined based on the outer ring detection parameters and the outer ring standard parameters, and a second offset parameter determined based on the outer ring detection parameters and the outer ring difference can be used as a reference for offset judgment.

[0082] In some implementations, the outer ring difference can be determined based on the outer ring detection parameters of the outer ring heating coil and the outer ring standard parameters.

[0083] Alternatively, the difference between the outer ring detection parameters and the outer ring standard parameters can be used as the outer ring difference value.

[0084] In some implementations, to further measure the offset, the ratio of the outer loop difference to the outer loop detection parameter can be used as a second offset parameter. Therefore, the larger the second offset parameter, the greater the degree of offset.

[0085] In one embodiment, the example is given with the driving frequency of the electromagnetic heating device as the heating detection parameter, the outer ring detection power as the outer ring detection parameter, and the power of the outer ring heating coil as the outer ring standard parameter.

[0086] Assuming the driving frequency of the electromagnetic heating device is fx, the standard parameter of the outer loop (i.e., the power of the inner loop heating coil in the state without offset) is P. 外环 If the outer loop detection power is Py, then the outer loop difference is: A2 = PP 外环 -Py; The second offset parameter is: B2 = A2 / P inner loop = (P 外环 -Py) / P 外环 .

[0087] In another embodiment, the heating detection parameter is the total power of the electromagnetic heating device, the inner loop detection parameter is the inner loop detection resonant current, and the inner loop standard parameter is the resonant current of the inner loop heating coil, as an example for explanation.

[0088] Assuming the total power of the electromagnetic heating device is Py, the standard parameter of the inner loop (i.e., the resonant current of the inner loop heating coil in the no-offset state) is I. 外环 If the inner loop resonance current is Iy, then the inner loop difference is: A2 = Iy - I 外环 The second offset parameter is: B2 = A2I 外环 =(Iy-I 外环 ) / I 外环 .

[0089] Step 340: Determine the offset distance based on the first offset parameter and the second offset parameter.

[0090] In the embodiments of this application, the offset can be determined by combining the operating parameters of the outer ring heating coil and the inner ring heating coil.

[0091] In the embodiments of this application, the offset distance is the distance between the centerline of the cooking pot and the centerline of the electromagnetic heating device, such as... Figure 3 As shown, the offset distance is d. It can be understood that the larger the offset distance, the farther the cooking pot is from the center of the electromagnetic heating device, and the greater the impact on cooking.

[0092] In some implementations, step 340 includes the following steps.

[0093] (1) Determine the preset mapping relationship corresponding to the heating detection parameters; the preset mapping relationship characterizes the correspondence between the offset distance and the first offset parameter and the second offset parameter.

[0094] (2) Based on the preset mapping relationship, determine the offset distance corresponding to the first offset parameter and the second offset parameter.

[0095] In the embodiments of this application, a preset mapping relationship corresponding to the heating detection parameters can be pre-set; that is, different heating detection parameters correspond to different preset mapping relationships. The preset mapping relationship characterizes the correspondence between the offset distance and the first offset parameter and the second offset parameter. The preset mapping relationship can be obtained in advance through experimental testing.

[0096] For example, if the heating detection parameter is the driving frequency of the electromagnetic heating device, then when the driving frequency is 30Hz, the preset mapping relationship is shown in Table 1.

[0097] Table 1

[0098] 0～0.05 0～0.2 0~10mm 0.05～0.1 0.2～0.4 10~20mm

[0099] For example, if the heating detection parameter is the driving frequency of the electromagnetic heating device, then when the driving frequency is 40Hz, the preset mapping relationship is shown in Table 2.

[0100] Table 2

[0101] 0.05～0.2 0.2～0.46 0~10mm 0.2～0.4 0.46～0.56 10~20mm

[0102] It is understood that this application is not limited thereto. The above-mentioned preset mapping relationship can be adjusted according to the specific electromagnetic heating equipment used. The above-mentioned preset mapping relationship will also change depending on the type, model, and operating parameters of the electromagnetic heating equipment.

[0103] Therefore, the offset distance corresponding to the first offset parameter and the second offset parameter can be determined according to the preset mapping relationship.

[0104] For example, when the driving frequency is 40Hz, if the preset mapping relationship in Table 2 is selected, and the first offset parameter is 0.1 and the second offset parameter is 0.2, then the offset distance can be determined to be 0 to 10mm.

[0105] Step 350: When the offset distance meets the control conditions, execute the offset control measures corresponding to the offset distance.

[0106] It is understandable that the greater the offset distance, the greater the impact on the cooking effect. Therefore, corresponding control measures can be implemented based on the offset distance value to reduce the impact on the cooking effect.

[0107] In some implementations, step 350 includes: when the offset distance is greater than a preset deviation threshold, performing offset control measures corresponding to the offset distance.

[0108] Understandably, when the offset distance is less than or equal to the preset offset threshold, the degree of offset of the cooking pot has little impact on the cooking effect, so it does not need to be controlled.

[0109] Optionally, the preset offset threshold can be set to 0–2 mm. It is understood that the smaller the preset offset threshold, the higher the sensitivity of the offset control method in this application, but the energy consumption of the electromagnetic heating device will increase. Therefore, the specific value can be selected according to the actual requirements of sensitivity and energy consumption, and this application does not impose any restrictions on this.

[0110] In some implementations, the steps of performing offset control measures corresponding to the offset distance include the following steps.

[0111] (1) When the offset distance is less than or equal to the preset control threshold, the adjustment range is determined according to the offset distance; wherein, the preset control threshold is greater than the preset deviation threshold; the larger the offset distance, the larger the corresponding adjustment range.

[0112] (2) Reduce the total power of the electromagnetic heating equipment according to the adjustment range.

[0113] In the embodiments of this application, when the offset distance is between a preset deviation threshold and a preset control threshold, the impact of cookware offset on the cooking effect can be reduced by adjusting the operating parameters of the electromagnetic heating device. It is understood that the larger the offset distance, the greater the impact on the cooking effect, and the greater the adjustment required.

[0114] In some implementations, the adjustment range can be determined based on the offset distance. For example, the adjustment range is 5% when the offset distance is 0-10mm; 20% when the offset distance is 10-20mm; and 30% when the offset distance is 20-30mm. It is understood that this application is not limited thereto, and the adjustment range can be set according to actual usage needs.

[0115] Therefore, the total power of the electromagnetic heating equipment can be reduced according to the adjustment range.

[0116] In some implementations, reducing the total power of the electromagnetic heating device can be achieved by reducing the power of the inner ring heating coil, thereby reducing the total power of the electromagnetic heating device.

[0117] In other embodiments, reducing the total power of the electromagnetic heating device can be achieved by reducing the power of the outer ring heating coil, thereby reducing the total power of the electromagnetic heating device.

[0118] In some other embodiments, reducing the total power of the electromagnetic heating device can be achieved by reducing both the power of the outer ring heating coil and the power of the inner ring heating coil.

[0119] In other embodiments, the step of performing offset control measures corresponding to the offset distance further includes: when the offset distance is greater than a preset control threshold, performing at least one of shutdown measures and reminder measures.

[0120] In the embodiments of this application, when the offset distance exceeds a preset control threshold, it severely affects the cooking effect. Therefore, a shutdown measure can be implemented, i.e., stopping the electromagnetic heating device from continuing to work; alternatively, a reminder measure can be implemented, such as issuing a warning message about the pot offset or audibly reminding the user. Alternatively, the above measures can be combined, for example, implementing a reminder measure followed by a shutdown measure.
