[0050] To address the problems existing in related technologies, this application provides a control method applied to electronic devices such as computers, mobile terminals, and pressure cookers. The mobile terminal may include mobile phones, tablets, etc. In some embodiments, the electronic device may be a controller for the pressure cooker. The functions implemented by the control method provided in this application can be achieved by the processor of the electronic device calling program code, wherein the program code can be stored in a computer storage medium.

[0051] Example One

[0052] This application provides a control method. Figure 1 This is a schematic diagram illustrating the implementation flow of a control method provided in an embodiment of this application, as shown below. Figure 1 As shown, it includes:

[0053] Step S101: When the pressure cooker has reached the target stage, obtain the critical pressure of the pressure cooker at the target stage and the current temperature of the heating element of the pressure cooker.

[0054] In this embodiment, a button is provided on the pressure cooker, allowing the user to select the pressure cooker's mode. Each mode may include multiple stages, such as a heating stage, a pressurizing stage, and a pressure-holding stage. The target stage can be any one of the heating or pressurizing stages. Each stage of each mode corresponds to different power information, taste information, and pressure-holding time. The electronic device can acquire the power information, taste information, and pressure-holding time to determine the critical pressure value of the pressure cooker.

[0055] In some embodiments, users can control the pressure cooker to start working through a control APP. The control APP allows users to select power information, taste information, and pressure holding time for each stage of the pressure cooker's operation. The electronic device obtains the power information, taste information, and pressure holding time from the control APP to determine the critical pressure value.

[0056] In this embodiment, to save on the cost of the pressure cooker, a single-sensor pressure cooker is used, with a temperature sensor located at the bottom and none at the top. In this embodiment, the current temperature of the heating element of the pressure cooker can be obtained using the temperature sensor. The heating element can be a heating plate.

[0057] Step S102: Determine the current temperature of the water in the pot based on the current temperature, and determine the current pressure based on the current temperature of the water in the pot.

[0058] In this embodiment of the application, the current temperature of the water in the pot corresponding to the current temperature can be determined based on the current temperature and the second correspondence, wherein the second correspondence includes the correspondence between the temperature of the heating element and the temperature of the water in the pot.

[0059] In this embodiment of the application, the temperature of the heating element and the temperature of the water in the pot can be measured, and then a second correspondence can be calculated based on the power heat dissipation.

[0060] In this embodiment of the application, determining the current pressure based on the current temperature of the water in the pot includes:

[0061] The current pressure is determined based on the current temperature of the water in the pot and a first correspondence, wherein the first correspondence includes the correspondence between the pressure and the temperature of the water in the pot.

[0062] Prior to step S102, the method further includes:

[0063] Step S1: Obtain the sample temperature of the water in the pot.

[0064] In this embodiment of the application, the sample temperature may include multiple temperature values.

[0065] Step S2: Input the sample temperature into the first calculation model to calculate the sample pressure corresponding to the sample temperature; wherein, the first calculation model includes: Among them, P 0 For sample pressure, T W 0 Let A be the temperature of the water in the pot, and let A, B, and C be constants.

[0066] In this embodiment, the Antoni equation, derived from engineering experiments, is applicable to the calculation of the saturated vapor pressure of most compounds. In a pressure cooker, water molecules are heated in a sealed space, making it perfectly suited to the Antoni equation. This equation allows for accurate calculation of the steam pressure inside the cooker, enabling precise pressure control throughout the cooking process.

[0067] Sample pressure P 0The corresponding temperature value T of the water in the pot W 0 The determination of the pressure is as follows. The Antone three-parameter steam equation can be used to determine the pressure-boosting method of this pressure cooker. Where P is the pressure unit (MPa), and T is the water temperature in the pot (Kelvin, K). ABC are equation constants. The parameters for water are A = 9.3876, B = 3826.36, and C = 45.47. By transforming this formula, the relationship between the water temperature and pressure in the pot can be obtained, i.e. Substituting the sample temperature into the equation yields the sample pressure, i.e. The unit value here is Kelvin, and it needs to be calculated according to the formula t. W 0 =T W 0 -273.75 converts Kelvin to Celsius. Following this logic, the first correspondence between pressure and water temperature in a specific order can be obtained.

[0068] Step S3: Establish the first correspondence between the sample pressure and the temperature of the water in the pot.

[0069] In some embodiments, prior to step S102, the method further includes:

[0070] Step S11: Obtain actual test data, wherein the actual test data includes: test pressure and water temperature inside the pot.

[0071] Step S12: Fit the test pressure and the temperature of the water in the pot to obtain a fitting curve.

[0072] Step S13: Determine the first correspondence between pressure and water temperature in the pot based on the fitted curve.

[0073] Step S103: The current pressure to the critical pressure is divided into segments based on a preset time interval to obtain multiple segmented pressures.

[0074] In this embodiment of the application, step S103 can be implemented through the following steps:

[0075] Based on a preset time interval, the current pressure to the critical pressure is segmented using a second calculation formula to obtain multiple segmented pressures. The second calculation formula is:

[0076]

[0077] Where P is pressure, t represents time, I represents the total current of the pressure cooker, R represents the resistance of the heating element, K and H represent heat dissipation coefficients, A, B, and C are constants, and T0 represents the current temperature of the water inside the pot. Where P is the pressure unit (MPa), T is the temperature unit (Kelvin), and ABC are equation constants: A = 9.3876, B = 3826.36, and C = 45.47.

[0078] In this embodiment, the temperature of the water in the pot can be calculated using the following formula:

[0079]

[0080] Where k and H are heat dissipation coefficients, which are related to the heat dissipation area, heat transfer medium, flow velocity of the heat transfer medium, thermal conductivity of related materials, and tightness of contact between heat transfer surfaces.

[0081] Solving the integral yields make

[0082] but

[0083]

[0084] Taking the exponent of the constant e on both sides, we get the second formula:

[0085]

[0086] In this embodiment of the application, the preset time interval can be configured. For example, the preset time interval can be 1 second, and the pressure of each segment can be calculated based on the second calculation formula.

[0087] Step S104: Determine the segment temperature of the water in the pot corresponding to each segment pressure, and determine the heating time corresponding to each segment temperature.

[0088] In this embodiment of the application, since there is a corresponding relationship between each pressure and the temperature of the water in the pot, after the pressure is divided into segments, the segment temperature of the water in the pot corresponding to each segment pressure can be determined.

[0089] In this embodiment of the application, the heating time corresponding to each segment temperature can be calculated based on a third calculation formula, wherein the third calculation formula is:

[0090]

[0091] Among them, T W Let t2 be the temperature corresponding to each segment, and t1 be the heating time for that segment. This process can be repeated to obtain the heating time for each segment temperature: t2-t1, t3-t2, ... t n -tn-1 To control the heating plate, simply turn it on at the specified time.

[0092] Step S105: Based on the heating time corresponding to each segment temperature, control the heating element to heat, so as to complete the work of the target stage.

[0093] In this embodiment, multi-stage duty cycle heating is used, which makes the heating plate heat evenly. The temperature changes steadily during the heating and pressurization stages. There are no sudden pressure increases during the heating and pressurization stages, and no need to consume a lot of time for pressure relief. The heating time is precisely controlled, thereby greatly shortening the cooking time.

[0094] In this embodiment, the time eliminated by continuous multi-stage duty cycle heating is equal to the sum of the depressurization times of each stage. The depressurization time of each stage can be used to input the water temperature values ​​inside the pot before and after depressurization: T W The original function of F(t) is G(t) obtained by calculation from G(t2)-G(t1).

[0095] This application provides a control method that, when a pressure cooker reaches a target stage, acquires the critical pressure of the pressure cooker at that target stage and the current temperature of the heating element of the pressure cooker; determines the current temperature of the water inside the cooker based on the current temperature, and determines the current pressure based on the current temperature of the water inside the cooker; segments the current pressure to the critical pressure based on a preset time interval to obtain multiple segmented pressures; determines the segmented temperature of the water inside the cooker corresponding to each segmented pressure, and determines the heating time corresponding to each segmented temperature; and controls the heating element to heat based on the heating time corresponding to each segmented temperature to complete the work of the target stage.
