[0024] The technical solution of the present application is further described in detail below with reference to the accompanying drawings and embodiments.

[0025] Figure 1 FIG. 1 is a flow chart of a method for detecting movement of a cooking utensil according to an embodiment of the present application. Figure 1 As shown, the method comprises the following steps:

[0026] Step 102: Detecting a first position of a cooking utensil on a cooking platform; the first position corresponds to at least one first target induction coil of the cooking platform;

[0027] Step 104: heating the cooking utensil using the at least one first target induction coil;

[0028] Among them, the cooking platform can be a multi-induction coil cooking platform, also known as an induction heating device. The cooking platform can be a cooking device made using the principle of electromagnetic induction. The cooking platform can include multiple induction coils. The induction coils can detect the position of cooking utensils placed on the cooking platform and heat the cooking utensils to cook the ingredients in the cooking utensils. The cooking platform can be an induction cooker, an induction range, etc.; the cooking utensils can include but are not limited to enamel pots, woks and frying pans, etc.

[0029] Step 106: acquiring a first electrical signal of each of the first target induction coils at a first moment and a second electrical signal at a second moment; the second moment being a moment after the first moment;

[0030] The electrical signal may be a current signal or a voltage signal; the interval between the first moment and the second moment may be 0.01 seconds, 0.02 seconds, etc.

[0031] Step 108: When a change trend of at least one of the first electrical signal and the corresponding second electrical signal satisfies a first condition, it is determined that the cooking appliance has moved.

[0032] Among them, since the electrical signal on the coil when the cooking utensil covers the coil is different from the electrical signal on the coil when the cooking utensil does not cover the coil, the movement of the cooking utensil on the cooking platform can be detected by detecting the change of the electrical signal flowing through the same coil at two moments before and after; for example, when the change trend of the electrical signals on multiple coils is large, it can be determined that the cooking utensil has moved, and when the change trend is small, it can be determined that the cooking utensil has not moved.

[0033] like Figure 2 As shown, the cooking platform 20 may include an induction coil 21, a support frame 22, a support panel 23 and an operating unit 24, wherein: the induction coil 21 is used to detect the position of the cooking utensil and perform induction heating; the support frame 22 is used to support the entire cooking platform system; the support panel 23 is used to cover the induction coil 21 to play a supporting role; the operating unit 24 is used for the user to operate; the support panel 23 can be placed on the upper surface of the support frame 22, and the induction coils 21 can be closely arranged in sequence below the support panel 23, as shown in FIG. Figure 2 As shown, 38 induction coils can be arranged in a honeycomb shape.

[0034] In one embodiment, Figure 3 As shown, the cooking utensil 30 can be placed on the cooking platform 31. At this time, the first position of the cooking utensil 30 corresponds to the position of the coils C1 to C7. At this time, the coils C1 to C7 pressed by the cooking utensil 30 can detect that the cooking utensil 30 is placed on the coils. After the user executes the heating instruction, the cooking utensil 30 can start to be heated through C1 to C7.

[0035] In an embodiment of the present application, when a cooking utensil is placed on a cooking platform and a coil on the cooking platform pressed by the cooking utensil heats the cooking utensil, whether the cooking utensil has moved is determined by detecting changes in an electrical signal on the coil, thereby being able to more accurately and efficiently determine whether the cooking utensil has moved.

[0036] In some embodiments, Figure 4 As shown, step 102 of “detecting the first position of the cooking utensil on the cooking platform” can be implemented by the following steps 121 and 122:

[0037] Step 121: when it is detected that the frequency change value of the pulse signal emitted by the excitation source corresponding to the induction coil is greater than a first threshold, the induction coil is determined as a first target induction coil;

[0038] Step 122: Determine a first position of the cooking utensil on the cooking platform based on the position corresponding to the first target induction coil.

[0039] The frequency change value is the amount of change in frequency. Compared with the case where no cooking utensil is placed on the induction coil, when the cooking utensil is placed on the induction coil, the frequency of the pulse signal emitted by the excitation source corresponding to the induction coil will decrease. Therefore, the amount of change in the frequency of the pulse signal can be used to determine the cooking utensil placed on the corresponding induction coil when the frequency change value is large. The first position of the cooking utensil can be determined based on the positions of all induction coils (i.e., the first target induction coil) whose frequency change amounts (i.e., the decrease amounts) are greater than the first threshold.

[0040] In the embodiment of the present application, whether a cooking utensil is placed on the induction coil is determined by the change in the frequency of the pulse signal corresponding to the induction coil, so that the placement position of the cooking utensil on the cooking platform can be determined more accurately and efficiently.

[0041] In some embodiments, Figure 5 As shown, the first electrical signal includes a first current value, and the second electrical signal includes a second current value; step 106 "obtaining the first electrical signal of each first target induction coil at the first moment and the second electrical signal at the second moment" can be implemented by the following steps 161 and 162:

[0042] Step 161: based on preset transformation parameters, convert the acquired third current value flowing through each of the first target induction coils at the first moment to obtain a corresponding first current value;

[0043] Step 162: Based on the transformation parameter, convert the acquired fourth current value flowing through each of the first target induction coils at the second moment to obtain a corresponding second current value.

[0044] Among them, Figure 6 As shown, the first target induction coils C1 to C n Heating is performed, wherein C1 to C n The coils that can be pressed by cooking utensils, C1 to C n They can be connected in parallel with each other, and the heating power source 60 can be a power source of electromagnetic heating mode, and the heating power source 60 can be C1 to C n Heating, D1 to D n It can be a heating current sensing device, also known as a current sensing device, which is used to detect the current flowing through the induction coils C1 to C n For example, the heating current sensing device D1 can be used to detect the current flowing through the induction coil C1, and the heating current sensing device D2 can be used to detect the current flowing through the induction coil C2, etc.

[0045] like Figure 7As shown, the current sensing device D1 is taken as an example for explanation. D1 can be a current transformer. Through the action of the current transformer, the third current value flowing through the induction coil C1 at the first moment can be converted into a first current value that can be detected by the detection processor 70 through the current sensing device D1. The third current value can be expressed as I1i, and the first current value can be expressed as I1o. The ratio between I1i and I1o is the transformation parameter. The transformation parameter can be expressed as N, that is, I1i / I1o=N, and N can be greater than 1.

[0046] Similarly, the fourth current value flowing through the induction coil C1 at the second moment can be converted into a second current value that can be detected by the detection processor 70 through the current sensing device D1. The fourth current value can be expressed as I2i, and the second current value can be expressed as I2o. The ratio between I2i and I2o is the transformation parameter N, that is, I2i / I2o=N.

[0047] Similarly, when n is greater than 1, the current flowing through the induction coil C at the first moment n The third current value on the current sensing device D n It can be converted into a first current value that can be detected by the detection processor, and flows through the induction coil C at the second moment n The fourth current value on the current sensing device D n It can be converted into a second current value that can be detected by the detection processor 70.

[0048] Correspondingly, step 108 "determining that the cooking utensil has moved when the changing trend of at least one of the first electrical signal and the corresponding second electrical signal meets the first condition" includes: determining that the cooking utensil has moved when the changing trend of at least one of the first current value and the corresponding second current value meets the first condition.

[0049] In the embodiment of the present application, the current value is transformed based on the transformation parameter, so that the current value can be reduced to a current value that can be detected by the detection processor, and the relative current value of the induction coil can be obtained more safely.

[0050] In some embodiments, Figure 8 As shown, step 108 "determining that the cooking appliance moves when the change trend of at least one of the first electrical signal and the corresponding second electrical signal meets the first condition" can be implemented by the following steps 180 to 186:

[0051] Step 180: Determine a ratio between each of the first current values ​​and the corresponding second current value;

[0052] In the case where the first moment is t0 and the second moment is t1, the induction coils C1 to C1 are detected at t0.n The first current values ​​on the induction coils C1 to C1 can also be expressed as I10, I20, ..., In0 respectively; at time t1, the induction coils C1 to C1 are detected. n The first current values ​​on the induction coils C1 to C n The ratio of the current at time t1 to that at time t0 can be expressed as d10, d20, ..., dn0, respectively, where d10 = I11 / I10, d20 = I21 / I20, ... dn0 = In1 / In0.

[0053] Step 182: Determine a maximum ratio and a minimum ratio from at least one of the ratios;

[0054] The maximum ratio may be expressed as d0max, the minimum ratio may be expressed as d0min, the maximum ratio may represent the maximum value from d10 to dn0, and the minimum ratio may represent the minimum value from d10 to dn0.

[0055] Step 184: Determine a difference value based on the maximum ratio and the minimum ratio;

[0056] Among them, the difference value can be expressed as x0, and the difference value can be the difference between the maximum ratio d0max and the minimum ratio d0min, that is, x0=(d0max-d0min); the difference value can also be the ratio between the maximum ratio d0max and the minimum ratio d0min, that is, x0=(d0max / d0min).

[0057] Step 186: When the difference value is greater than a second threshold, determine that the cooking appliance has moved.

[0058] The second threshold may be expressed as Xmove. When x0 is greater than Xmove, it may be considered that the cooking appliance has moved; otherwise, it may be considered that the cooking appliance has not moved.

[0059] In the embodiment of the present application, whether the cooking utensil has moved is determined by the current ratio of at least one induction coil at two moments, so that whether the cooking utensil has moved can be determined more accurately.

[0060] In some embodiments, Fig. 9 As shown, the method further includes the following steps 110 to 114:

[0061] Step 110: when the cooking utensil moves, stopping the at least one first target induction coil from heating the cooking utensil;

[0062] It should be noted that since the cooking utensil is heated by the first target induction coil at the covering position of the cooking utensil, if the cooking utensil moves, the energized induction coil will be exposed and radiate to the human body. It will also cause the cooking utensil to cover the unenergized induction coil, affecting the heating efficiency. Therefore, heating can be stopped when movement of the cooking utensil is detected.

[0063] Step 112: Detecting a second position of the cooking utensil on the cooking platform; the second position corresponds to at least one second target induction coil of the cooking platform;

[0064] After the heating is stopped, the position of the cooking appliance may be detected again to determine the second target induction coil to be energized.

[0065] Step 114: Utilize the at least one second target induction coil to heat the cooking utensil.

[0066] In an embodiment of the present application, by stopping heating when movement of the cooking utensil is detected, and heating the cooking utensil using the second target induction coil after re-detecting the position of the cooking utensil, the coil responsible for heating in the cooking platform can be adjusted at any time so that the energized coils are all located under the cooking utensil, thereby reducing the impact of radiation on the human body caused by the exposure of the energized induction coil and improving the heating efficiency.

[0067] In some embodiments, Fig.10 As shown, the method also includes:

[0068] Step 181: Determine the number of ratios of at least one of the ratios that are greater than a target ratio;

[0069] The target ratio may be expressed as d0t, and the number of ratios greater than the target ratio d0t among the n ratios (d10 to dn0) may be expressed as m.

[0070] Correspondingly, step 186 “determine that the cooking utensil has moved when the difference value is greater than a second threshold” may include: determining that the cooking utensil has moved when the difference value is greater than the second threshold and the number is greater than a third threshold.

[0071] Assuming that the third threshold is represented by p, when m is greater than p, it can be considered that more than a preset number of energized coils are exposed, which will produce a stronger degree of radiation to the human body and will also cause the cooking appliance to cover a preset number of unpowered induction coils, greatly affecting the heating efficiency. Therefore, in this case, it can be determined that the cooking appliance has moved.

[0072] In the embodiment of the present application, the number of coils with a larger ratio can be further determined, so that the movement of the cooking utensil can be determined only after the radiation intensity exceeds a certain range, and then the coil responsible for heating on the cooking platform can be adjusted according to the position of the cooking utensil. The heating coil can be adjusted as few times as possible, thereby increasing the life of the cooking platform, reducing the impact of radiation on the human body and improving the heating efficiency of the cooking platform.

[0073] In some embodiments, Fig.11 As shown, the method further includes the following steps 116 and 118:

[0074] Step 116: Acquire a third electrical signal of each of the second target induction coils at a third moment; the third moment is a moment after the second moment;

[0075] The third electrical signal may be a fifth current value. The sixth current value flowing through the second target induction coil at the third moment may be converted into a fifth current value detectable by the detection processor by the current sensing device. The third moment may be represented as moment t2. At moment t2, the induction coils C1 to C n The first current values ​​on can also be expressed as I12, I22, ..., In2 respectively.

[0076] Step 118: When the variation trend of at least one of the second electrical signal and the corresponding third electrical signal meets the second condition, it is determined that the cooking appliance moves again.

[0077] Among them, the induction coils C1 to C n The ratio of the current at time t2 to that at time t1 can be expressed as d11, d21, ..., dn1, respectively, where d11 = I12 / I11, d20 = I22 / I21, ... dn0 = In2 / In1.

[0078] The maximum ratio among the ratios can be expressed as d1max, the minimum ratio can be expressed as d1min, the difference between the maximum ratio and the minimum ratio can be expressed as x1, and the difference can be the difference between the maximum ratio d1max and the minimum ratio d1min, that is, x1=(d1max-d1min); the difference can also be the ratio between the maximum ratio d1max and the minimum ratio d1min, that is, x1=(d1max / d1min); when x1 is greater than Xmove, it can be considered that the cooking utensil has moved, otherwise it is considered that the cooking utensil has not moved; and so on, continue to record the electrical signal at the next moment until the user cancels the heating action.

[0079] In the embodiment of the present application, during the cooking process, the changes in the electrical signal flowing through the coil between the previous and next moments can be continuously detected, the movement of the cooking utensils on the cooking platform can be detected, and the coil responsible for heating can be adjusted in time to reduce radiation and improve heating efficiency.

[0080] Fig.12 A flow chart of a method for detecting movement of a cooking utensil provided in an embodiment of the present application is shown in FIG. Fig.12 As shown, the method comprises the following steps:

[0081] Step 1201: Start the cooking platform to heat the cooking utensils;

[0082] The user can place the cooking utensils on the cooking platform, and the induction coils C1 to C n It is detected that a cooking utensil is placed thereon; the user selects a heating power and starts the cooking platform to heat the cooking utensil.

[0083] Step 1202: Record the current value of each coil at the current moment;

[0084] Among them, the current time can be expressed as t m , at t m The current value of each coil at this moment can be expressed as I1m to Inm respectively.

[0085] Step 1203: Record the current value of each coil at the next moment;

[0086] Among them, the next moment can be expressed as t m+1 , at t m+1 The current value of each coil at a given moment can be expressed as I1(m+1) to In(m+1) respectively.

[0087] Step 1204: Record the current ratio of each coil at the next moment and the current moment;

[0088] The current ratio of each coil can be expressed as d1m to dnm.

[0089] Step 1205: Record the maximum and minimum values ​​of the current ratio;

[0090] Wherein, the maximum value can be expressed as dmmax, and the minimum value can be expressed as dmmin;

[0091] Step 1206: Determine whether the difference between the maximum value and the minimum value is greater than a threshold value; if so, execute step 1207; if not, execute step 1208;

[0092] The difference value may be expressed as Xm, and the threshold value may be expressed as Xmove. When Xm is greater than Xmove, it may be considered that the cooking utensil has moved; otherwise, the cooking utensil has not moved.

[0093] Step 1207: the cooking utensil moves at the next moment, and the position detection of the cooking utensil needs to be performed again;

[0094] Step 1208: The cooking appliance has not moved.

[0095] At this time, the current value of each coil has not changed, that is, I1(m+1)=I1m, ..., In(m+1)=Inm. After step 1208 is executed, step 1204 can be executed until the user cancels the heating action.

[0096] In the related art, the current flowing through the coil is detected, and then a stable point is determined. The difference between the detection and the stable point is used to determine the movement of the pot. The related art relies heavily on the determination of the stable point. Once the stable point is inaccurate, for example, the pot has been moved before the stable point is reached, the pot movement detection will fail.

[0097] In the embodiment of the present application, when the cooking utensil is placed on the cooking platform and the coil pressed by the cooking utensil heats the cooking utensil, the movement of the pot during heating can be detected by detecting the change of the current flowing through the coil.

[0098] In an embodiment of the present application, a cooking device composed of a plurality of induction coils is provided. After a cooking utensil is placed on a platform of the cooking device, the cooking utensil is heated by the coil pressed by the cooking utensil. At a certain time interval, the current value flowing through each coil is recorded at each moment. The ratio of the current values ​​of the same coil at two moments before and after is calculated. The current ratios of all the pressed coils are compared, and when the difference between the maximum value and the minimum value reaches a certain threshold value, it is considered that the cooking utensil has moved. After the cooking utensil has moved, the heating power source can be turned off first, the static position detection (i.e., the position of the cooking utensil on the cooking platform) can be re-performed, and then the heating power can be turned on again.

[0099] It should be noted that in the embodiment of the present application, if the above-mentioned mobile detection method of the cooking utensil is implemented in the form of a software function module and sold or used as an independent product, it can also be stored in a computer-readable storage medium. Based on such an understanding, the technical solution of the embodiment of the present application can be essentially or partly reflected in the form of a software product that contributes to the relevant technology. The computer software product is stored in a storage medium, including several instructions to enable an electronic device (which can be a mobile phone, a tablet computer, a desktop computer, a personal digital assistant, a navigator, a digital phone, a video phone, a television, a sensor device, etc.) to execute all or part of the methods described in each embodiment of the present application. The aforementioned storage medium includes: various media that can store program codes, such as a U disk, a mobile hard disk, a read-only memory (ROM), a magnetic disk or an optical disk. In this way, the embodiment of the present application is not limited to any specific combination of hardware and software.
