Detailed Description
In order that the above-recited objects, features and advantages of the present application will be more clearly understood, a more particular description of the application will be rendered by reference to the appended drawings and appended detailed description. It should be noted that, without conflict, the embodiments of the present application and features in the embodiments may be combined with each other.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application, however, the present application may be practiced in other ways than those described herein, and the scope of the application is therefore not limited to the specific embodiments disclosed below.
An embodiment of a first aspect of the present application provides a control method of a cooking apparatus, the cooking apparatus including an electromagnetic heating device.
Fig. 1 shows a flow chart of a control method of a cooking apparatus according to a first embodiment of the present application. Wherein the method comprises the following steps:
102, obtaining the resonant frequency or the resonant period of an electromagnetic heating device;
step 104, controlling the electromagnetic heating device according to the change rate of the resonance frequency or the change rate of the resonance period.
According to the control method of the cooking equipment, in the heating process of the cooking equipment, the temperature change can cause the resistance and inductance of the electromagnetic heating device to change, and the resonant frequency formula is adoptedWhen the inductance L changes, the resonance frequency f changes since the capacitance C is unchanged. Compared with normal heating, the inductor L has larger change during dry heating, the resonant frequency drops faster, and the reciprocal resonant period of the resonant frequency rises faster. Therefore, according to the change rate of the resonant frequency or the change rate of the resonant period, whether dry burning occurs can be determined, so that the electromagnetic heating device is controlled, the accuracy of high-temperature protection of the cooking equipment is improved, the cooker deformation caused by the dry burning of the cooker is prevented, and the service life of the cooking equipment is prolonged. In addition, compared with the prior art that the temperature sensor is used for detecting the temperature for high-temperature protection, the electromagnetic heating device is used for high-temperature protection according to the heating principle of the electromagnetic heating device, the temperature sensor is not required to be arranged, and the cost is reduced.
It should be noted that, after the electromagnetic heating device operates for a preset period of time, the resonant frequency or the resonant period of the electromagnetic heating device is obtained, so as to ensure that the resonant frequency or the resonant period is accurate data obtained in a state that the electromagnetic heating device operates stably, thereby improving the accuracy of high-temperature protection.
In some embodiments, the cooking apparatus may be an induction cooker, which carries a pot of metal material, and the electromagnetic heating device uses an electromagnetic induction ((Induction Heating, IH) heating principle to generate eddy currents on the metal material by using electric current, thereby generating heat to heat the pot.
In the above embodiment, step 104, the step of controlling the electromagnetic heating device according to the rate of change of the resonant frequency or the rate of change of the resonant period specifically includes: and controlling the electromagnetic heating device to stop heating based on the absolute value of the change rate of the resonant frequency being greater than the first frequency change rate threshold or the change rate of the resonant period being greater than the first period change rate threshold.
In this embodiment, the rate of change is also represented by the slope of the curve of the resonant frequency or resonant period, and an increase in temperature may cause a rapid decrease in the resonant frequency or a rapid increase in the resonant period of the electromagnetic heating device. Therefore, if the absolute value of the change rate of the resonant frequency is greater than the first frequency change rate threshold value, or the change rate of the resonant period is greater than the first period change rate threshold value, and the temperature is too high, the electromagnetic heating device is controlled to stop heating, so that high-temperature protection is realized.
In some embodiments, the first frequency change rate threshold, the first periodic change rate threshold may be determined according to the material and/or capacity of the cookware carried by the cooking device, e.g., the first frequency change rate threshold is 3, the first periodic change rate threshold is 3.
In any of the foregoing embodiments, step 104, controlling the electromagnetic heating device according to the rate of change of the resonant frequency or the rate of change of the resonant period specifically includes: acquiring duration time when the absolute value of the change rate of the resonant frequency is larger than the first frequency change rate threshold value, or duration time when the change rate of the resonant period is larger than the first period change rate threshold value; and controlling the electromagnetic heating device to stop heating based on the duration time being greater than the time threshold.
In this embodiment, a duration is obtained in which the absolute value of the rate of change of the resonance frequency is greater than the first frequency rate threshold, or the rate of change of the resonance period is greater than the first period rate threshold, and when the duration is greater than the time threshold, the electromagnetic heating device is controlled to stop heating. The conditions of the movement of the cooker, the water adding (cold water or hot water) in the cooker and the like have great influence on the change of the resonant frequency or the resonant period, but the conditions of the movement of the cooker and the water adding in the cooker are almost completed in a transient time (for example, 1 second), so that the conditions cause the change of the resonant frequency or the resonant period in a short time, and the accuracy of temperature judgment is improved by judging the duration, and the situation of misjudgment is avoided.
In some embodiments, the time threshold may be determined based on the material and/or capacity of the cookware carried by the cooking device, e.g., the time threshold is 7s.
Fig. 2 shows a flow chart of a control method of a cooking apparatus according to a second embodiment of the present application. Wherein the method comprises the following steps:
step 202, obtaining the resonant frequency or resonant period of an electromagnetic heating device;
step 204, controlling the electromagnetic heating device according to the change rate of the resonant frequency based on the resonant frequency being in the frequency threshold range, or controlling the electromagnetic heating device according to the change rate of the resonant period based on the resonant period being in the period threshold range.
In this embodiment, when the resonance frequency is in the frequency threshold range or the resonance period is in the period threshold range, the electromagnetic heating device is controlled according to the change rate of the resonance frequency or the resonance period, and the temperature is determined more accurately by combining the frequency range or the period range.
In any of the above embodiments, the frequency threshold range and the period threshold range may be determined according to the material and/or the capacity of the cookware carried by the cooking device. In this embodiment, the cookers with different materials and/or capacities have different values in the frequency threshold range or the cycle threshold range, so as to protect the cookers at high temperature, improve the accuracy of the high temperature protection, and improve the use safety of the cooking equipment.
It should be noted that, the material and/or the capacity of the pan can be determined by detecting the pan, for example, an image of the pan is collected, the image is compared with pre-stored data, the material and/or the capacity of the pan is determined, and then the frequency threshold range or the period threshold range is determined.
Fig. 3 shows a flow chart of a control method of a cooking apparatus according to a third embodiment of the present application. Wherein the method comprises the following steps:
step 302, obtaining the resonant frequency or the resonant period of the electromagnetic heating device;
step 304, obtaining the power of the electromagnetic heating device and/or the current of the electromagnetic heating device;
step 306, controlling the electromagnetic heating device according to the rate of change of the resonant frequency or the rate of change of the resonant period based on the power being in the power threshold range and/or the current being in the current threshold range.
In the embodiment, the power of the electromagnetic heating device and/or the current of the electromagnetic heating device are divided into different grades, and dry combustion is judged together with the resonant frequency or the resonant period frequency under the different grades, so that the electromagnetic heating device is controlled, and the accuracy of high-temperature protection is improved. For example, the current changes greatly when the pot moves, water (cold water or hot water) is added into the pot, and the like, so that the problem of misjudgment can be avoided by limiting the current within the current threshold range.
In any of the above embodiments, the power threshold range may be determined according to the material and/or capacity of the cooking apparatus; the current threshold range may be determined based on the material and/or capacity of the cookware carried by the cooking device. In the embodiment, cookers with different materials and/or capacities have different values of a power threshold range and a current threshold range, so that the high-temperature protection of different cookers is realized, the accuracy of the high-temperature protection is improved, and the use safety of cooking equipment is improved.
It should be noted that, the material and/or the capacity of the pan can be determined by detecting the pan, for example, an image of the pan is collected, the image is compared with pre-stored data, the material and/or the capacity of the pan is determined, and then the power threshold range and the current threshold range are determined.
In some embodiments, after determining the power threshold range according to the material and/or capacity of the cookware carried by the cooking device, a corresponding frequency threshold range, period threshold range, and current threshold range may be determined according to the power threshold range.
Fig. 4 shows a flow chart of a control method of a cooking apparatus according to a fourth embodiment of the present application. Wherein the method comprises the following steps:
step 402, obtaining a resonant frequency or a resonant period of an electromagnetic heating device;
step 404, obtaining power of the electromagnetic heating device and current of the electromagnetic heating device;
step 406, controlling the electromagnetic heating device according to the change rate of the resonant frequency based on the power being in the power threshold range, the current being in the current threshold range, and the resonant frequency being in the frequency threshold range; or controlling the electromagnetic heating device according to the change rate of the resonance period based on the power being in the power threshold range, the current being in the current threshold range and the resonance period being in the period threshold range.
As the temperature increases, the resonant frequency decreases and the resonant period increases. For example, when P > P1 (P represents power), the resonance frequency e [ a1, B1], the current e [ a, B ], and if the absolute value Δf of the slope of the resonance frequency change in Δt time period exceeds T, temperature protection is performed and heating is stopped. When P2< P < P1, the resonant frequency E [ C1, D1], the current E [ C, D ], if the absolute value Deltaf of the slope of the resonant frequency change in the Deltat time period is more than or equal to Deltaf 2, the temperature protection is carried out, and the heating is stopped. When P < P2, the resonance frequency E [ E1, F1], the current E [ E, F ], if the absolute value Deltaf of the slope of the resonance frequency change within Deltat time period is more than or equal to Deltaf 3, the temperature protection is carried out, and the heating is stopped. The magnitude relation of e1< f1< c1< d1< a1< b1, A, B, C, D, E, F is not limited, but the upper limit value of a section is definitely larger than the lower limit value of the section. The resonance frequency range and the current range can be different according to the material and the size of the cooker.
When P > P1, the resonance period E [ a2, B2] is shown in FIG. 5, the current E [ A, B ] is shown in FIG. 6, and if the duration of the slope Deltaf'. Gtoreq.Deltaf1 of the resonance period change in Deltat time period exceeds T, the temperature protection is carried out, and the heating is stopped. When P2< P < P1, the resonance period E [ C2, D2] is shown in FIG. 7, the current E [ C, D ] is shown in FIG. 8, and if the slope Deltaf'. Gtoreq.Deltaf2 of the resonance period change in the Deltat time period exceeds T, the temperature protection is carried out, and the heating is stopped. When P < P2, the resonance period E [ E2, F2] is shown in FIG. 9, and the current E [ E, F ] is shown in FIG. 10, if the slope Deltaf'. Gtoreq.Deltaf3 of the resonance period change in the Deltat time period exceeds T, the temperature protection is carried out, and the heating is stopped. The numerical value magnitude relation of Δf1< Δf2< Δf3, f2> e2> d2> c2> b2> a2, A, B, C, D, E, F is not limited, but the upper limit value of one section is definitely larger than the lower limit value of the section. The resonance period range and the current range can be different in value according to different materials and sizes of cookware.
Taking a special small pot as an example, the resonant frequency at this time is the calculated frequency.
When P is more than 1000W (P represents power), if the resonant frequency E [0, 320], the current E [48, 136] are heated, and the absolute value of the slope of the resonant frequency is more than 2 for more than 7s in a certain time, the temperature is judged to be too high, and the heating is stopped.
When 700W < P <1000W, if the resonant frequency epsilon [312, 414] is heated, if the current epsilon [46, 82] is within a certain period, the absolute value of the slope of the resonant frequency is more than 7s, and the temperature is judged to be too high, and the heating is stopped.
When P <700W, if the resonant frequency E [602, 793] is heated, if the current E [32, 73] is the current, the absolute value of the slope of the resonant frequency is more than 4 for more than 7s in a certain time, the temperature is judged to be too high, and the heating is stopped.
