The application discloses a pressure calibration and detection method for an electronic pressure cooker. A pressure cooker enters a pressure point recording mode; when the pressure inside the pressurecooker rises, a heating plate acting film deforms to adjust an iron core position of a pressure sensor, so that the iron core and a coil of the pressure sensor make displacement to change the inductance value; the variable of the inductance value is transformed into a corresponding frequency value by a conversion circuit; a processing chip records and stores information; when the pressure insidethe pressure cooker is being a pressure P1 and a pressure P2 respectively, the processing chip records corresponding frequency values H1 and H2 respectively; on the basis of the P1, P2, H1, and H2, apressure curve slope C is calculated, wherein the C meets a formula: C=|H2-H1|/(P2-P1); a frequency value X is collected in real time; when the X is larger than or equal to H1, the current pressure PXin the pressure cooker meets a formula: PX=[P1-(X-H1)/C]; and when the X is less than the H1, the current pressure PX in the pressure cooker meets a formula: PX=[P1+(H1-X)/C]. Therefore, the detection efficiency, detection accuracy and pressure cooker quality are improved.

The invention relates to the technical field of cooking utensils, and particularly provides a control method and device of a cooking utensil, and the cooking utensil. The control method comprises the steps that at the boiling phase, the boiling phase is divided into a plurality of heating intervals in advance according to the heating time after entering into the boiling phase, the corresponding heating power is preset in each heating interval, and along with increasing of the heating time, the heating power corresponding to the multiple heating intervals is decreased sequentially; and the top temperature of a cooking cavity is detected, when the top temperature is not increased any more, the heating time after entering into the boiling phase is detected, and when the heating time reaches any heating interval, the cooking cavity is heated at the heating power corresponding to the heating interval. According to the control method, during congee cooking, the problem that at the boiling phase, congee is too thick, and consequently the bottom is dry-burned is effectively avoided.

Control method and device of cooking utensil and cooking utensil

The embodiment of the invention provides a method and device for judging the rice and water amount in a cooking utensil and the cooking utensil, and belongs to the field of cooking utensils. The method includes the steps that at the water absorption stage, the relevant temperature, detected by a temperature detector, of the cooking utensil is received; a heater is controlled to carry out heating according to the received relevant temperature of the cooking utensil, so that the relevant temperature of the cooking utensil is kept at preset temperature; the cumulative heating duration and the cumulative heating frequency within preset time in the water absorption stage are calculated; the rice and water amount in the cooking utensil is determined according to the calculated cumulative heatingduration and the calculated cumulative heating frequency. The rice and water amount in the cooking utensil can be determined in the water absorption process of rice cooking without additionally arranging devices, thus, the production cost is reduced, the controllability of the rice cooking process is enhanced, and the cooking effect is improved.
