[0028] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of this application without making creative efforts are within the scope of protection of this application.

[0029] The terms "first", "second", etc. in this application are used to distinguish different objects rather than to describe a specific order. In addition, the terms "include", "have" and any variations thereof are intended to cover non-exclusive inclusions.

[0030] It should be noted that when an element is fixed to another element, it includes fixing the element directly to the other element, or fixing the element to the other element through at least one other element in the middle. When an element is connected to another element, it includes connecting the element directly to the other element, or connecting the element to the other element through at least one other element in the middle.

[0031] This application first proposes a calibration method for cooking equipment, such as Figures 1 to 2 As shown, Figure 1 This is a flow chart of the first embodiment of the calibration method for cooking equipment of the present application. Figure 2 yes Figure 1Schematic diagram of a specific process flow of step S12 in an embodiment of the present invention. The cooking device includes a cooking mechanism and a detection element for measuring a pressure signal from the cooking mechanism. The cooking mechanism includes, for example, a pot, a lid, a heating mechanism (e.g., a heating plate), etc. The detection element is disposed within the pot, lid, heating mechanism, or the cooking body of the pot and is configured to measure and output a pressure signal from the cooking mechanism. The pressure signal is a signal that reflects the pressure value within the cooking mechanism.

[0032] Optionally, the detection element may include a displacement sensor, such as a potentiometer-type displacement sensor, a capacitive displacement sensor, or a linear displacement sensor. In some embodiments, the cooking mechanism may further include an elastic member, such as an elastic diaphragm, disposed in correspondence with the pot, lid, or heating mechanism so as to move with the pot, lid, or heating mechanism. The displacement sensor may detect the displacement of the elastic member to indirectly obtain the displacement of the pot, lid, or heating mechanism as the displacement of the cooking mechanism, and output a corresponding pressure signal.

[0033] The calibration method specifically includes the following steps S11 to S13.

[0034] Step S11: obtaining a target pressure value of the cooking device and a pressure signal output by the detection component at the target pressure value based on calibration requirements.

[0035] Based on the calibration requirements, a target pressure value of the cooking device is obtained. The target pressure value is a preset pressure condition. After the cooking device reaches the target pressure value, a pressure signal output by the detection component at the target pressure value is obtained.

[0036] Optionally, the target pressure value is normal pressure, that is, the atmospheric pressure of the current environment. The target pressure value can usually be set to a value within the range of 0-120kPa, without specific limitation, such as 99kPa, 1.2kPa, 11kPa and other values. In an application scenario, the control mechanism of the cooking equipment can obtain the atmospheric pressure of the current environment as the target pressure value.

[0037] Optionally, the pressure value inside the cooking mechanism can be adjusted to the target pressure value by another pressure control and regulation mechanism of the cooking device itself (such as other detection components of the cooking device) or an external pressure control and regulation mechanism (such as a maintenance instrument or a calibrator, etc.), and then the pressure signal of the cooking device at this target pressure value output by the detection component of the cooking device is obtained. After the calibration is completed, the detection component can be used to control the operation of the cooking device.

[0038] In some embodiments, the cooking mechanism includes, for example, a pot, a lid, a heating mechanism (e.g., a heating plate), etc. When the detection member of this embodiment includes a displacement detection member, the displacement detection member may be disposed within the pot, the lid, the heating mechanism, or the cooking body of the pot. The displacement detection member is used to directly detect the displacement of the pot, the lid, or the heating mechanism as a pressure signal of the cooking mechanism. The displacement detection member may include a displacement sensor, such as a potentiometer-type displacement sensor, a capacitive displacement sensor, or a linear displacement sensor.

[0039] In some embodiments, the cooking mechanism may further include an elastic member, such as an elastic diaphragm, which is arranged corresponding to the pot body, lid body or heating mechanism so as to move with the pot body, lid body or heating mechanism; the displacement detection member can detect the displacement of the elastic member to indirectly obtain the displacement of the pot body, lid body or heating mechanism as a pressure signal of the cooking mechanism.

[0040] Optionally, the cooking device may generate a calibration request based on a user's calibration operation. The calibration operation may be a key operation, such as a single key or multiple keys, or a voice input, or other signal input recognizable by the cooking device, such as a Bluetooth control signal from an external device. The external device may be a tester or a calibrator.

[0041] In other embodiments, the timing of "obtaining the target pressure value of the cooking device and the pressure signal output by the detection component at the target pressure value" may also be that the cooking device obtains a processing result after comprehensive processing based on environment, time and other information, confirms the calibration requirement based on this processing result, and then obtains the target pressure value of the cooking device and the pressure signal output by the detection component at the target pressure value based on this calibration requirement.

[0042] Step S12: obtaining a calibration value based on the first preset relationship, the target pressure value and the pressure signal.

[0043] Specifically, the target pressure value and the pressure signal can be substituted into the first preset relationship as known quantities to obtain a calibration value, wherein the pressure signal can be the frequency or pulse width of the signal, or other signal parameters.

[0044] It should be noted that the first preset relationship is the correspondence between the pressure value within the cooking device and the pressure signal. Since there is a one-to-one correspondence between the pressure value within the cooking device and the pressure signal output by the detection element, this correspondence can be determined in advance and stored in the cooking device as the first preset relationship for use in cooking control.

[0045] Optionally, the first preset relationship is provided with a constant and an unknown quantity, and step S12 can be performed by Figure 2 The method is implemented, specifically comprising step S21:

[0046] Step S21: Substitute the target pressure value and the pressure signal as known quantities into the first preset relationship, and calculate the unknown quantity as a calibration value.

[0047] Substituting the target pressure value and the corresponding pressure signal as known quantities into the first preset relationship can obtain the value of the unknown quantity, which is the calibration value.

[0048] In this way, the calibration value can be calculated using the target pressure value and the corresponding pressure signal, which can improve the accuracy of the calibration value.

[0049] Step S13: using the calibration value to update the first preset relationship to a second preset relationship, and using the second preset relationship as cooking control information of the cooking device.

[0050] Since the correspondence between the pressure value inside the cooking device and the pressure signal output by the detection element depends on the state of the detection element, the state of the detection element is not necessarily fixed and unchanging. For example, there may be operational errors during the production, assembly, maintenance and reinstallation of the cooking device, which may cause the initial state of the detection element (for example, when the detection element is a displacement sensor, the initial position state of the displacement sensor) to have an error compared with the standard state; for example, after the cooking device has been used for a period of time, the detection element may age and deform, and the performance or structure may differ from the initial state; for example, there may be structural or performance errors between the multiple detection elements corresponding to the multiple cooking devices produced. Various situations may cause the correspondence between the pressure value inside the cooking device and the pressure signal output by the detection element to change. In order to improve the accuracy of the "correspondence between the pressure value inside the cooking device and the pressure signal output by the detection element", and thus improve the accuracy of the pressure detection of the cooking device during the cooking process, the cooking device can be calibrated. After the calibration is completed, the cooking device can use the detection element in the calibration method to output the pressure signal and perform normal pressure-controlled cooking based on the second preset relationship, which can improve the pressure control accuracy.

[0051] For example, after the cooking equipment is produced and ready to leave the factory, the cooking equipment can be calibrated according to this calibration method to improve the pressure control accuracy and the pressure control consistency between multiple products; for another example, after the user receives the product and before using it for the first time, the user can set the calibration operation, and the cooking equipment obtains the calibration requirements based on this calibration operation, so that the cooking equipment is calibrated according to this calibration method to improve the pressure control accuracy and thus improve the cooking effect; for another example, after the product has been used for a long time or after repair and reinstallation, the cooking equipment is calibrated according to this calibration method to improve the pressure control accuracy and thus improve the cooking effect.

[0052] The beneficial effect of this embodiment is that, based on calibration requirements, the target pressure value of the cooking device and the pressure signal output by the detection element at the target pressure value are obtained, a calibration value is obtained based on the first preset relationship, the target pressure value, and the pressure signal, the first preset relationship is updated to a second preset relationship using the calibration value, and the second preset relationship is used as cooking control information for the cooking device. In this way, the present embodiment can calibrate the cooking device based on the calibration requirements, thereby improving the convenience of calibration of the cooking device. Furthermore, the present embodiment obtains the calibration value based on the first preset relationship, the target pressure value, and the pressure signal, and uses the calibration value to update the first preset relationship to obtain the second preset relationship, and uses the second preset relationship as the cooking control information for the cooking device. This allows the second preset relationship to more accurately reflect the correspondence between the pressure value and the pressure signal within the cooking device, making the second preset relationship more consistent with actual requirements, thereby achieving more accurate pressure detection and less deviation. Therefore, this configuration can improve the accuracy of pressure detection and pressure control of the cooking device, thereby improving cooking results, increasing the consistency of product pressure control, and enhancing the user experience. Therefore, this embodiment can improve the pressure control accuracy of the cooking equipment, improve the cooking effect, and can also improve the consistency of product pressure control, thereby improving the user experience.

[0053] It should be noted that, before calibration begins, the correspondence between the cooking device's pressure value and the pressure signal output by the detection element, pre-stored within the cooking device, is the first preset relationship. The second preset relationship in this application refers to a new correspondence obtained by updating this first preset relationship. For example, after production and before shipment, a product can undergo a calibration control operation to obtain a second preset relationship, which can then be used to control the cooking device in subsequent use. After the product has been used for a period of time after leaving the factory, it can undergo another calibration control operation. During this calibration control process, the second preset relationship obtained at the end of the previous calibration will be used as the first preset relationship in this calibration control process.

[0054] In other embodiments, similar improvements can be made to the calibration method, which will not be described in detail here.

[0055] This application further proposes a calibration method for cooking equipment, such as Figure 3 As shown, Figure 3 1 is a flow chart of a second embodiment of a calibration method for a cooking device of the present application. The cooking device includes a cooking mechanism and a detection element for measuring a pressure signal of the cooking mechanism. The calibration method specifically includes the following steps S31 to S33.

[0056] Step S31: When the cooking device is powered on, the pressure of the cooking device is adjusted to a target pressure value based on a calibration requirement, and a pressure signal output by the detection component at the target pressure value is obtained.

[0057] Specifically, after the cooking device is powered on, it can control its operation using a first preset relationship pre-stored in the cooking device. When the cooking device receives a calibration request, it initiates calibration based on the calibration request. The pressure of the cooking device can be adjusted to a target pressure value using an external device, such as a tester or calibrator, or the device's own pressure control mechanism can be used to adjust the pressure of the cooking device to the target pressure value, while simultaneously obtaining a pressure signal output by a detection component at this target pressure value. It should be noted that when the device's own pressure control mechanism is used to adjust the pressure of the cooking device to the target pressure value, a different pressure detection component is used, rather than the detection component corresponding to the calibrated preset relationship.

[0058] Step S32: obtaining a calibration value based on the first preset relationship, the target pressure value and the pressure signal.

[0059] For the specific implementation method, please refer to step S12 of the above embodiment.

[0060] Step S33: using the calibration value to update the first preset relationship to a second preset relationship, and using the second preset relationship as cooking control information of the cooking device.

[0061] For the specific implementation method, please refer to step S13 of the above embodiment.

[0062] The beneficial effect of this embodiment is that when the cooking device is powered on, the pressure of the cooking device is adjusted to the target pressure value based on the calibration requirements and the corresponding pressure signal is obtained, which facilitates reducing the error between the actual pressure value and the target pressure value in the cooking device and improving the accuracy of the calibration method.

[0063] In other embodiments, the target pressure value may be preset as normal pressure, and the target pressure value and the corresponding pressure signal output by the detection component may be directly obtained.

[0064] In other embodiments, similar improvements can be made to the calibration method, which will not be described in detail here.

[0065] This application further proposes a calibration method for cooking equipment, such as Figure 4 As shown, Figure 4 1 is a flow chart of a third embodiment of a calibration method for a cooking device of the present application. The cooking device includes a cooking mechanism and a detection element for measuring a pressure signal of the cooking mechanism. The calibration method specifically includes the following steps:

[0066] Step S41: obtaining a target pressure value of the cooking device and a pressure signal output by the detection component at the target pressure value based on a calibration requirement.

[0067] The specific implementation method can refer to step S11 of the above embodiment.

[0068] Step S42: obtaining a calibration value based on the first preset relationship, the target pressure value and the pressure signal.

[0069] For the specific implementation method, please refer to step S12 of the above embodiment.

[0070] Step S43: Compare the calibration value with the first calibration threshold.

[0071] It should be noted that the first calibration threshold is preset and stored in the cooking device. The first calibration threshold is the lower limit of the range of valid calibration values ​​corresponding to the range of valid pressure signals allowed to be output by the detection component under the target pressure value condition during calibration. The first calibration threshold mainly depends on the performance of the detection component. For example, when the detection component is a displacement sensor, the first calibration threshold mainly depends on the limited range of the displacement sensor.

[0072] Step S44: In response to the calibration value being less than the first calibration threshold, determining that the calibration is abnormal, and using the first preset relationship as cooking control information of the cooking device.

[0073] Specifically, when the calibration value is less than the first calibration threshold, the calibration value is determined to be an abnormal calibration value, and the calibration is confirmed to be abnormal, and the first preset relationship is used as the cooking control information of the cooking device.

[0074] In this way, abnormal calibration values ​​can be effectively identified, reducing the risk of using abnormal calibration values ​​to update the first preset relationship to the second preset relationship, thereby reducing the occurrence of cooking pressure control failures caused by using abnormal second preset relationships to control the operation of cooking equipment, thereby affecting cooking effects, thereby improving cooking pressure control accuracy and improving cooking effects.

[0075] Optionally, after confirming that the calibration is abnormal, the cooking device can be controlled to alarm, and the alarm method can be one or more forms such as flashing display lights, displaying characters, and emitting alarm sounds.

[0076] Optionally, the calibration method of this embodiment may further include step S45:

[0077] Step S45: In response to the calibration value being greater than or equal to the first calibration threshold, the calibration value is used to update the first preset relationship to a second preset relationship, and the second preset relationship is used as cooking control information of the cooking device.

[0078] Specifically, when the calibration value is greater than or equal to the first calibration threshold, it means that the calibration value is above the lower limit of the calibration value corresponding to the pressure signal allowed to be output by the detection component. The calibration value is then used to update the first preset relationship to the second preset relationship, and the second preset relationship is used as the cooking control information of the cooking device.

[0079] In this way, when the calibration value is in a normal state, the calibration process can be successfully completed using the calibration value, which can improve the pressure control accuracy of the cooking equipment and thus improve the cooking effect.

[0080] In other embodiments, similar improvements can be made to the calibration method, which will not be described in detail here.

[0081] This application further proposes a calibration method for cooking equipment, such as Figure 5 As shown, Figure 5 1 is a flow chart of a fourth embodiment of a calibration method for a cooking device of the present application. The cooking device includes a cooking mechanism and a detection element for measuring a pressure signal of the cooking mechanism. The calibration method specifically includes the following steps:

[0082] Step S51: obtaining a target pressure value of the cooking device and a pressure signal output by the detection component at the target pressure value based on a calibration requirement.

[0083] The specific implementation method can refer to step S41 of the above embodiment.

[0084] Step S52: obtaining a calibration value based on the first preset relationship, the target pressure value and the pressure signal.

[0085] For the specific implementation method, please refer to step S42 of the above embodiment.

[0086] Step S53: Compare the calibration value with the first calibration threshold.

[0087] The specific implementation method can refer to step S43 of the above embodiment.

[0088] Step S54: In response to the calibration value being less than the first calibration threshold, determining that the calibration is abnormal, and using the first preset relationship as cooking control information of the cooking device.

[0089] The specific implementation method can refer to step S44 of the above embodiment.

[0090] Step S55: In response to the calibration value being greater than or equal to the first calibration threshold, the calibration value is compared with the second calibration threshold.

[0091] Specifically, the second calibration threshold is preset and stored in the cooking device. The second calibration threshold is greater than the first calibration threshold. The second calibration threshold is the upper limit of the effective calibration value corresponding to the effective pressure signal allowed to be output by the detection element when calibrating at the target pressure value. The upper limit mainly depends on the performance of the detection element. For example, when the detection element is a displacement sensor, the second calibration threshold mainly depends on the limited range of the displacement sensor.

[0092] Step S56: In response to the calibration value being greater than the second calibration threshold, determining that the calibration is abnormal, and using the first preset relationship as cooking control information of the cooking device.

[0093] Specifically, when the calibration value is greater than the second calibration threshold, cooking pressure control failure will result, so the calibration abnormality is confirmed and the cooking device is controlled using the pre-stored first preset relationship.

[0094] In this way, abnormal calibration values ​​can be effectively identified, reducing the risk of using abnormal calibration values ​​to update the first preset relationship to the second preset relationship, thereby reducing the occurrence of cooking pressure control failures caused by using abnormal second preset relationships to control the operation of cooking equipment, thereby affecting cooking effects, thereby improving cooking pressure control accuracy and improving cooking effects.

[0095] Optionally, after confirming that the calibration is abnormal, the cooking device can be controlled to alarm, and the alarm method can be one or more forms such as flashing display lights, displaying characters, and emitting alarm sounds.

[0096] Optionally, the calibration method of this embodiment further includes step S57:

[0097] Step S57: In response to the calibration value being less than or equal to the second calibration threshold, executing the step of updating the first preset relationship to a second preset relationship using the calibration value, and using the second preset relationship as cooking control information of the cooking device.

[0098] Specifically, when the calibration value is greater than or equal to the first calibration threshold and less than or equal to the second calibration threshold, it means that the calibration value is within the range of the calibration value corresponding to the pressure signal output by the detection component. The calibration value is then used to update the first preset relationship to the second preset relationship, and the second preset relationship is used as the cooking control information of the cooking device.

[0099] In this way, when the calibration value is in a normal state, the calibration process can be successfully completed using the calibration value, which can improve the pressure control accuracy of the cooking equipment and thus improve the cooking effect.

[0100] For example, when the detection element is a displacement sensor, the first preset relationship is a linear relationship and satisfies the following relationship formula 1-1:

[0101] P=K+a……Relationship 1-1

[0102] Wherein, a is an unknown quantity in the first preset relationship, and the K-pre coefficient is 1, which is a constant in the first preset relationship. a has a pre-stored initial value. For example, if the pre-stored initial value of a is 1, then when no calibration is performed, the first preset relationship when a is 1 is used to control the operation of the cooking device.

[0103] If the user has a calibration requirement, and the preset first calibration threshold is -5 and the second calibration threshold is 5, after starting the calibration, the cooking device is controlled to the target pressure value P0, and the pressure signal Kp0 output by the displacement sensor at the pressure P0 is obtained. Substitute P0 and Kp0 into the relationship formula 1-1 to obtain the value of a as (P0-Kp0). If (P0-Kp0) is within the value range of -5 to 5, it means that the calibration value is successfully obtained. Use (P0-Kp0) as the latest value of a, update the first preset relationship, and obtain the second preset relationship, as shown in the following relationship formula 1-2, and use the second preset relationship to control the operation of the cooking device.

[0104] P=K+(P0-Kp0)……Relationship 1-2

[0105] In other embodiments, similar improvements can be made to the calibration method, which will not be described in detail here.

[0106] The present application further proposes a cooking device. The cooking device of this embodiment includes a cooking mechanism, a detection component, and a control mechanism. The detection component is arranged on the cooking mechanism or in the cooking cavity of the cooking mechanism, and is used to measure the pressure signal of the cooking mechanism; the control mechanism is connected to the detection component and the cooking mechanism, and is used to control the operation of the cooking device using the above-mentioned calibration method.

[0107] Alternatively, as Figure 6 As shown, the cooking mechanism includes an inner pot 91, a pot cover 92, a heating mechanism, a displacement detection member 94, and an elastic diaphragm 95; the pot cover 92 is arranged on the cooking cavity of the inner pot 91; the heating mechanism is located at the bottom of the inner pot 91 and is used to heat the inner pot 91; the elastic diaphragm 95 is arranged below the heating mechanism and moves as the inner pot 91 moves up and down; the displacement detection member 94 is arranged corresponding to the elastic diaphragm 95 and is used to obtain the displacement of the elastic diaphragm 95.

[0108] The inner pot 91 can be displaced as the pressure in the cooking cavity changes, thereby driving the elastic diaphragm 95 to be displaced. The displacement detection part 94 can obtain the displacement of the elastic diaphragm 95 and can obtain the pressure condition in the cooking cavity of the inner pot 91 based on the displacement.

[0109] In other embodiments, the displacement detection member may also be provided corresponding to the inner pot, the pot cover or the heating mechanism to obtain the displacement of the inner pot, the pot cover or the heating mechanism.

[0110] Alternatively, the cooking device may be a pressure cooker, etc. The detection element may include a displacement sensor, such as a potentiometer-type displacement sensor, a capacitive displacement sensor, or a linear displacement sensor. The detection element may also be a pressure sensor or an air pressure sensor, and the detection element includes at least one of the displacement sensor, pressure sensor, or air pressure sensor. The control mechanism may include a control chip, such as an MCU, etc., or a non-integrated circuit with control and data processing functions.

[0111] In one application scenario, when the detection element is a displacement sensor, such as Figure 8 As shown, Q0, Q1, and Q2 represent the pressure signal curves output by the displacement sensor at different initial positions, respectively. The horizontal axis represents the pressure signal, and the vertical axis represents the pressure value. For example, at pressure P0, when the pressure signal output by the displacement sensor is Kp0, a calibration value within the range of the first calibration threshold and the second calibration threshold is obtained, thereby obtaining a second preset relationship. The relationship curve corresponding to the second preset relationship is Q0.

[0112] Specifically, on the Q0 curve, Kpmin is the first calibration threshold, for details, please refer to the above embodiment; Kpmax is the second calibration threshold, for details, please refer to the above embodiment; Kmin is the lower limit of the pressure signal output corresponding to the effective range of the displacement sensor under different displacement input states; Kmax is the upper limit of the pressure signal output corresponding to the effective range of the displacement sensor under different displacement input states; the relationship between the above four values ​​satisfies the relationship Kpmin<Kpmax; Kmin <Kmax。

[0113] The pressure signal can be expressed in the form of signal frequency, pulse width, etc.

[0114] In one application scenario, the cooking device is an electric pressure cooker, such as Figure 9 As shown, after the product is powered on, the pressure in the pot is controlled to be P1 through a specific operation S1; a calibration operation is generated based on the calibration requirement, and calibration is started based on the calibration operation, such as a specific operation S2, such as a specific operation of signal input such as key input, voice input, etc., that is, based on the calibration operation, the target pressure value P1 is obtained and the pressure signal Kp1 output by the detection component under the target pressure value P1 is obtained, for example, the pressure signal Kp1 at this time is recorded; a calibration value Kpx is obtained based on a first preset relationship, P1, and Kp1; the calibration value Kpx is compared with a first calibration threshold Kpmin; if the calibration value Kpx is less than the first calibration threshold Kpmin, the calibration is abnormal and an alarm is issued. The cooking equipment is controlled by using the first preset relationship, and the first preset relationship is not updated, and the calibration is completed; if the calibration value Kpx is greater than or equal to the first calibration threshold Kpmin, the calibration value Kpx is compared with the second calibration threshold Kpmax; if the calibration value Kpx is greater than the second calibration threshold Kpmax, the calibration is abnormal, and an alarm is issued, and the cooking equipment is controlled by using the first preset relationship, and the first preset relationship is not updated, and the calibration is completed; if the calibration value Kpx is less than or equal to the second calibration threshold Kpmax, the calibration is successful, and the first preset relationship is updated by using the calibration value Kpx to obtain the second preset relationship, and the cooking equipment is controlled by using the second preset relationship, and the calibration is completed.

[0115] For example, a cooking device's detection component is a displacement sensor. A first preset relationship stored within the cooking device satisfies Equation 1-1, with a pre-stored initial value of 1, a first calibration threshold of -5, and a second calibration threshold of 5. Before product 1, corresponding to the cooking device, is produced and shipped, it undergoes a calibration process to obtain a calibration value of 2. This results in the following second preset relationship, Equation 2-1. Equation 2-1 is then used to control the operation of the product 1.

[0116] P=K+2……Relationship 2-1

[0117] After a period of factory use, Product 1 has its displacement sensor reinstalled due to a faulty repair. After the repair, Product 1 is powered on and calibrated based on the calibration requirements to obtain the target pressure value and the corresponding pressure signal. If the new calibration value obtained based on Equation 2-1, the target pressure value, and the pressure signal is -6, and -6 is less than the first calibration threshold, Product 1 will confirm the calibration anomaly and issue an alarm, while continuing to control Product 1 using Equation 2-1. At this point, the maintenance technician can troubleshoot the issue, power on the product again, and initiate calibration. If the new calibration value obtained based on Equation 2-1, the target pressure value, and the pressure signal is 1, and 1 is within the range from the first calibration threshold to the second calibration threshold, then Equation 2-1 is updated with calibration value 1 to obtain Equation 2-2. Equation 2-2 will then be used to control Product 1 in subsequent use, and calibration is complete.

[0118] P=K+1……Relationship 2-2

[0119] For another example, a cooking device's detection component is a displacement sensor. A first preset relationship stored within the cooking device satisfies Equation 1-1, with a pre-stored initial value of 1, a first calibration threshold of -5, and a second calibration threshold of 5. Before product 2, corresponding to the cooking device, is produced and shipped, it undergoes a calibration process to obtain a calibration value of 0. This results in the following second preset relationship, Equation 3-1. Equation 3-1 is then used to control the operation of product 2.

[0120] P=K……Relationship 3-1

[0121] After Product 2 has been used for a period of time after leaving the factory, the elastic diaphragm in the displacement sensor has deformed due to long-term use. Based on the calibration requirements, Product 2 is powered on and calibrated to obtain the target pressure value and the corresponding pressure signal. If the new calibration value obtained based on Relationship 3-1, the target pressure value, and the pressure signal is -3, and -3 is within the range from the first calibration threshold to the second calibration threshold, the calibration value -3 is used to update Relationship 3-1 to obtain Relationship 3-2. Relationship 3-2 is then used to control the operation of Product 2 in subsequent use, and the calibration is completed.

[0122] P=K-3……Relationship 3-2

[0123] In other embodiments, similar improvements can be made to the cooking equipment, which will not be described in detail here.

[0124] This application further proposes a calibration method for cooking equipment, such as Figure 10 As shown, the cooking device includes a cooking mechanism and a detection component for measuring a pressure signal of the cooking mechanism. The calibration method specifically includes steps S101 to S104.

[0125] Step S101: obtaining a target pressure value of a cooking device and a pressure signal output by a detection component at the target pressure value based on a calibration requirement.

[0126] The specific implementation of step S101 can refer to step S11 and will not be repeated here.

[0127] Step S102: obtaining a calibration value based on the first preset relationship, the target pressure value and the pressure signal.

[0128] The specific implementation of step S102 can refer to step S12 and will not be repeated here.

[0129] Step S103: In response to the calibration value being less than the first calibration threshold or the calibration value being greater than the second calibration threshold, determining that the calibration is abnormal, and using the first preset relationship as cooking control information of the cooking device.

[0130] The first calibration threshold is less than the second calibration threshold. The first and second calibration thresholds constitute a valid calibration value interval. This interval corresponds to the valid calibration value interval allowed for the valid displacement signal output by the detection element when calibrating at the target pressure value. This interval primarily depends on the performance of the detection element. For example, when the detection element is a displacement sensor, the valid displacement signal interval output by the detection element primarily depends on the limited range of the displacement sensor. Therefore, the valid calibration value interval primarily depends on the limited range of the displacement sensor. If the calibration value is not within the interval formed by the first and second calibration thresholds, a calibration anomaly is determined, and the first preset relationship is used as cooking control information for the cooking device.

[0131] The above setting can effectively identify abnormal calibration values, reduce the risk of obtaining an abnormal second preset relationship using abnormal calibration values, and continue to use the first preset relationship as the cooking control information of the cooking equipment to improve the accuracy of pressure detection of the cooking equipment when calibration is abnormal, thereby improving the cooking effect.

[0132] Optionally, step S104: in response to the calibration value being greater than or equal to the first calibration threshold and the calibration value being less than or equal to the second calibration threshold, the first preset relationship is updated to a second preset relationship using the calibration value, and the second preset relationship is used as cooking control information of the cooking device.

[0133] When the calibration value is greater than or equal to the first calibration threshold and the calibration value is less than or equal to the second calibration threshold, that is, when the calibration value is within the valid calibration value range, the calibration value is used to update the first preset relationship to the second preset relationship, and the second preset relationship is used as the cooking control information of the cooking device, a more accurate "correspondence between the pressure value in the cooking device and the pressure signal output by the detection element" can be obtained, thereby improving the accuracy of pressure detection of the cooking device during the cooking process.

[0134] In other embodiments, steps S103 and S104 may not be included. After executing step S102, in response to the calibration value being less than the third calibration threshold, a calibration abnormality may be determined, and the first predetermined relationship may be used as cooking control information for the cooking device. Specifically, only the minimum valid calibration threshold of the calibration value (i.e., the third calibration threshold) may be set as a reference for determining a calibration abnormality, thereby reducing the complexity of the calibration method.

[0135] In other embodiments, steps S103 and S104 may not be included. After executing step S102, in response to the calibration value being greater than the fourth calibration threshold, a calibration abnormality may be determined, and the first predetermined relationship may be used as cooking control information for the cooking device. Specifically, only the maximum valid calibration threshold of the calibration value (i.e., the fourth calibration threshold) may be set as a reference for determining a calibration abnormality, thereby reducing the complexity of the calibration method.

[0136] Optionally, the detection element includes at least one of a displacement sensor, a pressure sensor, or an air pressure sensor, which can be used to measure and output a pressure signal of the cooking mechanism.

[0137] The present application further proposes a control method for a cooking device, wherein the cooking device includes a cooking mechanism and a detection component for measuring a pressure signal of the cooking mechanism. The calibration method specifically includes steps S111 to S114.

[0138] Step S111: Acquire a second preset relationship using the calibration method of the above embodiment.

[0139] Please refer to the above embodiments for details, which will not be described again here.

[0140] Step S112: obtaining the current pressure signal of the cooking mechanism output by the detection component.

[0141] The current pressure signal may be output by a calibrated detection component of the cooking device, and the current pressure signal corresponds to the current pressure value inside the cooking mechanism.

[0142] Step S113: obtaining a pressure value in the pot corresponding to the current pressure signal based on a second preset relationship;

[0143] Step S114: Cooking is performed based on the pressure value in the pot.

[0144] Based on the calibrated second preset relationship and the current pressure signal, a corresponding pot pressure value, i.e., the current pot pressure value, is obtained. The cooking device can then perform cooking operations based on the current pot pressure value. Using the calibrated second preset relationship to control cooking operations can provide a more accurate "correspondence between the pressure value within the cooking device and the pressure signal," thereby improving the pressure control accuracy of the cooking mechanism.

[0145] The present application further proposes a cooking device. The cooking device of this embodiment includes a cooking mechanism, a detection component, and a control mechanism. The detection component is arranged on the cooking mechanism or in the cooking cavity of the cooking mechanism, and is used to measure the pressure signal of the cooking mechanism; the control mechanism is connected to the detection component and the cooking mechanism, and is used to control the operation of the cooking device using the above-mentioned control method.

[0146] The structural principle and implementation method of the cooking device can be found in the above embodiments and will not be described in detail here.

[0147] The control method can be found in the above embodiments and will not be described in detail here.

[0148] This application further proposes a computer storage medium, such as Figure 7 As shown, Figure 7 The computer storage medium 100 stores program instructions 101, which are executed by a processor to implement the above-mentioned calibration method or control method.

[0149] The program instructions 101 may be formed into a program file and stored in the aforementioned storage medium in the form of a software product, so that an electronic device (which may be a personal computer, server, or network device, etc.) or a processor executes all or part of the steps of the various embodiments of the present application. The aforementioned storage medium includes: a USB flash drive, a mobile hard drive, a read-only memory (ROM), a random access memory (RAM), a magnetic disk, or an optical disk, etc., which can store program code, or a terminal device such as a computer, server, mobile phone, or tablet.

[0151] In one embodiment, a computer program product or computer program is provided, the computer program product or computer program including computer instructions stored in a computer storage medium. A processor of an electronic device reads the computer instructions from the computer storage medium and executes the computer instructions, causing the electronic device to perform the steps of each of the above method embodiments.

[0152] In addition, if the above functions are implemented as software functions and sold or used as independent products, they can be stored in a storage medium readable by a mobile terminal. That is, the present application also provides a storage device storing program data, which can be executed to implement the methods of the above embodiments. The storage device can be, for example, a USB flash drive, an optical disk, a server, etc. In other words, the present application can be embodied in the form of a software product, which includes a number of instructions for causing a smart terminal to execute all or part of the steps of the methods described in each embodiment.

[0153] Different from the prior art, the present application can obtain a target pressure value of a cooking device and a pressure signal output by a detection element at the target pressure value based on calibration requirements, obtain a calibration value based on a first preset relationship, the target pressure value, and the pressure signal, use the calibration value to update the first preset relationship to a second preset relationship, and use the second preset relationship as cooking control information for the cooking device. In this way, the present application can calibrate the cooking device based on calibration requirements, thereby improving the convenience of calibration of the cooking device. The present application also obtains a calibration value based on the first preset relationship, the target pressure value, and the pressure signal, uses the calibration value to update the first preset relationship to obtain a second preset relationship, and uses the second preset relationship as cooking control information for the cooking device. This allows the second preset relationship to more accurately reflect the correspondence between the pressure value and the pressure signal within the cooking device, making the second preset relationship more consistent with actual requirements, thereby achieving more accurate pressure detection and less deviation. Therefore, this configuration can improve the accuracy of pressure detection and pressure control of the cooking device, thereby improving cooking results, increasing the consistency of product pressure control, and enhancing the user experience. Therefore, this application can improve the pressure control accuracy of cooking equipment, improve cooking effects, and improve the consistency of product pressure control, thereby improving user experience.
