In this embodiment, if the bluetooth connection is not established when the cooking control request triggered by the pressure cooker function button 112 is received, the induction cooker 10 cannot determine whether the pot on the heating panel is the pressure cooker 20, and the processor controls the induction cooker 10 to operate at the power corresponding to the function of the induction cooker 10. In this embodiment, when the induction cooker 10 heats other pans, for example, when the frying pan is used for cooking, the constant high power stable operation can be used for realizing quick cooking, so as to improve the cooking efficiency, and therefore, when the bluetooth connection is not established, the induction cooker 10 is controlled to operate with the power corresponding to the function of the induction cooker 10.
In another embodiment, when the pressure inside the pressure cooker 20 is not obtained within a preset time interval, the processor controls the induction cooker 10 to operate at a power corresponding to the function of the induction cooker 10.
In this embodiment, after the induction cooker 10 is controlled to operate at the power corresponding to the function of the pressure cooker 20, when the pressure inside the pressure cooker 20 is not obtained within the preset time interval, it is possible that the current pressure cooker 20 is located within the working range of the first bluetooth module 12 but not located on the heating panel of the induction cooker 10, that is, the cooker on the heating panel of the induction cooker 10 is another type of cooker, and therefore, the processor controls the induction cooker 10 to operate at the power corresponding to the function of the induction cooker 10, so as to improve the cooking efficiency. Certainly, when the pressure inside the pressure cooker 20 is not obtained within the preset time interval, the cooker on the heating panel of the induction cooker 10 is a possible pressure cooker 20, but the pressure acquisition module 22 of the pressure cooker 20 has a fault, and in order to ensure the cooking safety, the induction cooker 10 is controlled to operate with the power corresponding to the function of the induction cooker 10.
Preferably, in another embodiment, the processor acquires the pressure inside the pressure cooker 20 collected by the pressure collecting module 22 of the pressure cooker 20 in real time through the bluetooth connection; when the obtained pressure inside the pressure cooker 20 is higher than a preset pressure, the processor updates the overpressure times, wherein the overpressure times are times when the pressure inside the pressure cooker 20 is higher than or equal to the preset pressure; and when the updated overpressure times are larger than the preset times, the processor controls the induction cooker 10 to operate at the power corresponding to the heat preservation function.
Wherein, preset pressure carries out reasonable setting according to discharge valve 25 of pressure cooker 20 to when making the pressure in pressure cooker 20 reach this preset pressure, can open this discharge valve 25 through the pressure that gaseous production in pressure cooker 20, in order to realize the exhaust of pressure cooker 20, specifically, this preset pressure can be set to 70 KP. The preset times can be reasonably set according to actual needs, for example, the preset times is 3.
In this embodiment, when the electromagnetic oven 10 operates with power corresponding to the function of the pressure cooker 20, the processor acquires the pressure inside the pressure cooker 20 collected by the pressure collecting module 22 of the pressure cooker 20 in real time through the bluetooth connection, so as to control the heating power of the electromagnetic oven 10 according to the pressure inside the pressure cooker 20. When the induction cooker 10 is operated at a power corresponding to the function of the pressure cooker 20, the processor resets the number of overpressures, for example, sets the number of overpressures to 0, and updates the number of overpressures, i.e., adds one to the number of overpressures, when the obtained pressure inside the pressure cooker 20 is greater than the preset pressure. And then when the times that the pressure inside the pressure cooker 20 is greater than the preset pressure are greater than the preset times, the induction cooker 10 operates with the power corresponding to the heat preservation function, so that the pressure cooker 20 is subjected to heat preservation, and the taste and the aroma of the cooked food are improved.
Preferably, in an embodiment, when the time length of the electromagnetic oven 10 operating at the power corresponding to the function of the pressure cooker 20 reaches a preset time length, the processor obtains a first pressure inside the pressure cooker 20 at the current time and a second pressure inside the pressure cooker 20 when the electromagnetic oven 10 operating at the power corresponding to the function of the pressure cooker 20; the processor calculating a difference between the first pressure and the second pressure; and when the difference value is smaller than a preset difference value, the processor controls the induction cooker 10 to operate at the power corresponding to the function of the induction cooker 10.
Wherein the difference between the first pressure and the second pressure refers to an absolute value of a difference between the first pressure and the second pressure. Generally, the first pressure is greater than the second pressure when the induction cooker 10 is heated, and thus, the difference is greater than 0. The preset difference value can be reasonably set according to actual conditions.
In this embodiment, after the induction cooker 10 operates with the power corresponding to the function of the pressure cooker 20, when the time length that the induction cooker 10 operates with the power corresponding to the function of the pressure cooker 20 reaches the preset time length, the processor obtains a first pressure inside the pressure cooker 20 at the current time, and a second pressure inside the pressure cooker 20 when the induction cooker 10 operates with the power corresponding to the function of the pressure cooker 20, wherein the processor may obtain the second pressure and store the second pressure when the induction cooker 10 operates with the power corresponding to the function of the pressure cooker 20. When the difference is greater than or equal to the preset difference, it indicates that the current pressure cooker 20 is being heated, and when the difference is smaller than the preset difference, it indicates that the current pressure cooker 20 is not heated, that is, the cooker heated by the induction cooker 10 is not the pressure cooker 20, so that the induction cooker 10 is controlled to operate at the power corresponding to the function of the induction cooker 10, so as to improve the working efficiency of the induction cooker 10.
It should be noted that the technical solutions of the embodiments of the present invention can be combined with each other, but it must be based on the realization of those skilled in the art, and when the technical solutions are combined and contradictory or can not be realized, one should think that the combination of the technical solutions does not exist, and it is not within the protection scope of the present invention.
The above only is the preferred embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structural changes made by the contents of the specification and the drawings, or the direct or indirect application in other related technical fields, are included in the same way in the protection scope of the present invention.
