[0032] 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.

[0033] 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.

[0034] 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.

[0035] This application first proposes a calibration method for cooking equipment, such as Figures 1 to 4 As shown, Figure 1 This is a flow chart of an embodiment of a calibration method for a cooking device of the present application. Figure 2 yes Figure 1 A schematic flow chart of an embodiment of step S11 in the embodiment; Figure 3 for Figure 1 A flow chart of another embodiment of step S11 in the embodiment; Figure 4 for Figure 3 Schematic diagram of a flow chart of an embodiment of step S33 in an embodiment. The cooking device of this embodiment includes a cooking mechanism and a displacement detection element for measuring the displacement of the cooking mechanism. The cooking mechanism includes, for example, a pot, a pot lid, a heating mechanism (such as a heating plate), etc. The displacement detection element of this embodiment is disposed within the pot, pot lid, heating mechanism, or the cooking body of the pot. The displacement detection element is used to directly obtain the displacement of the pot, pot lid, or heating mechanism as the displacement of the cooking mechanism. The displacement detection element may include a displacement sensor, such as a potentiometer displacement sensor, a capacitive displacement sensor, or a linear displacement sensor.

[0036] 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 the displacement of the cooking mechanism.

[0037] Since the correspondence between the pressure value inside the cooking device and the displacement signal output by the displacement detection member depends on the state of the displacement detection member. The state of the displacement detection member is not necessarily fixed and unchanging. For example, there may be assembly errors during the production, assembly, or repair and reinstallation of the cooking device, which may cause the initial state of the displacement detection member (such as the initial position state of the displacement sensor) to have errors compared with the standard state; for example, after the cooking device has been used for a period of time, the displacement detection member may age and deform, and there may be differences in performance or structure compared with the initial state; for example, there may also be structural or performance errors between the multiple displacement detection members corresponding to the multiple cooking devices produced. Various situations will cause the correspondence between the pressure value inside the cooking device and the displacement signal output by the displacement detection member to change. In order to improve the accuracy of the "correspondence between the pressure value inside the cooking device and the displacement signal output by the displacement detection member", 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 displacement detection member in the calibration method to output the displacement signal and perform normal pressure-controlled cooking based on the second preset relationship. The calibration method of this embodiment specifically includes the following steps:

[0038] Step S11: acquiring a displacement signal output by a displacement detection member of the cooking device at a target pressure value in response to a trigger condition.

[0039] Specifically, in response to the trigger condition, after the cooking device reaches the target pressure value, the displacement signal output by the displacement detection member of the cooking device at the target pressure value is obtained. The target pressure value is normal pressure, that is, the atmospheric pressure of the current environment, usually in the range of 0-120kPa, but is not specifically limited, such as 99kPa, 1.2kPa, 11kPa, etc. It should be noted that the trigger condition can be the power-on state of the cooking device or a specific state of the displacement detection member or other conditions. The trigger condition can be pre-stored in the cooking device or set to be user-modifiable. This allows the cooking device to automatically start calibration when the specific trigger condition is met, without the user having to actively propose a calibration requirement. The calibration control can be automatically triggered when the cooking device reaches a certain state, and calibration can be automatically performed. This can improve the self-detection capability of the cooking device and improve the pressure control accuracy of the cooking device.

[0040] Optionally, step S11 may be implemented through step SA1, specifically as follows:

[0041] Step SA1: In response to a power-on instruction, a displacement signal output by a displacement detection member of the cooking device at a target pressure value is obtained.

[0042] In response to the power-on instruction, the displacement signal output by the displacement detection part of the cooking device under the target pressure value is obtained. The power-on instruction is used as the trigger condition, which is in line with the user's daily usage habits. In addition, this method does not require the user or the cooking device to provide additional trigger instructions, thereby improving the degree of automation of the calibration method, facilitating automatic calibration, and improving the user experience.

[0043] Optionally, step S11 can also be performed as follows: Figure 2 The method shown in FIG. 1 is implemented, specifically comprising steps S21 to S22:

[0044] Step S21: In response to the power-on instruction, start timing.

[0045] Specifically, in response to a power-on instruction, the calibration control process of the cooking device is automatically started, and timing begins after power-on.

[0046] Step S22: In response to the timing duration being greater than the preset duration, obtaining a displacement signal output by the displacement detection member of the cooking device at the target pressure value.

[0047] Specifically, the preset duration depends on the performance of the displacement detection element, primarily the time it takes for the displacement detection element to reach a stable state after power-on, and can be pre-stored within the cooking device. If the timed duration exceeds the preset duration, indicating that the displacement detection element has entered a stable state after power-on, a displacement signal output by the displacement detection element at a target pressure value of the cooking device is obtained. For example, the target pressure value can be 0 kPa, meaning that automatic calibration is performed at zero pressure in the cooking device, thereby obtaining a displacement signal of the cooking device at zero pressure after power-on.

[0048] The beneficial effect of steps S21 and S22 is that automatic calibration is performed after power-on, and the timing of obtaining the "displacement signal output by the displacement detection member of the cooking device at the target pressure value" is determined based on the relationship between the timing duration and the preset duration, thereby reducing the error in the initial state of the displacement detection member caused by assembly errors during production or repair and reinstallation of the displacement detection member, and reducing the state error of the displacement detection member caused by changes in the structure or performance of the displacement detection member itself after long-term use (for example, aging of the elastic diaphragm of the displacement sensor), thereby reducing the error in the correspondence between the pressure value of the cooking device and the displacement signal output by the displacement detection member caused by the state error of the displacement detection member, thereby reducing the pressure control error of the cooking device, improving the pressure control consistency between multiple cooking devices, and improving the cooking effect and user experience.

[0049] Optionally, when the timing duration is less than or equal to the preset duration, continue waiting.

[0050] Optionally, step S11 can also be performed as follows: Figure 3 The method shown in FIG. 1 is implemented, specifically comprising steps S31 to S34:

[0051] Step S31: In response to the power-on instruction, start timing.

[0052] The specific implementation method can refer to the above step S21.

[0053] Step S32: In response to the timing duration being greater than the preset duration, the cooking temperature of the cooking device is obtained.

[0054] Specifically, if the timing duration is greater than the preset duration, it proves that the displacement detection element enters a stable state after being powered on, and the cooking temperature of the cooking mechanism is further obtained.

[0055] Step S33: In response to the cooking temperature being less than or equal to the preset temperature, obtaining a displacement signal output by the displacement detection member of the cooking device at a target pressure value.

[0056] Specifically, the preset temperature is used to determine whether calibration can be performed. This value is set primarily to reduce the risk of significant deformation of the cooking device due to high temperatures, thereby reducing calibration errors caused by such deformation. For example, the preset temperature is set to 100°C and pre-set within the cooking device. If the cooking temperature is less than or equal to the preset temperature, it indicates that the cooking device has not significantly deformed due to the high temperature, and the calibration process can proceed normally. The displacement signal output by the displacement detection element of the cooking device at the target pressure value is obtained.

[0057] The beneficial effect of steps S31 to S33 is that the stability of the relevant structures of the cooking equipment can be judged from the two perspectives of the timing duration after power-on and the cooking temperature. Only when the timing duration is greater than the preset duration and the cooking temperature is less than or equal to the preset temperature, that is, the state of the displacement detection component is stable and the cooking equipment has not undergone a large deformation due to excessive temperature, the displacement signal output by the displacement detection component of the cooking equipment at the target pressure value is further obtained. This can improve the accuracy of the target pressure value and its corresponding displacement signal obtained during the calibration process, thereby improving the accuracy of the obtained calibration value, improving the accuracy of the calibration method, and thereby improving the pressure control accuracy of the cooking equipment.

[0058] Optionally, step S33 can be performed as follows Figure 4 Steps S41 to S43 shown are implemented as follows:

[0059] Step S41: In response to the cooking temperature being less than or equal to the preset temperature, determining whether the current pressure value of the cooking device is equal to the target pressure value.

[0060] Specifically, in response to the cooking temperature being less than or equal to the preset temperature, it indicates that the cooking device has not undergone significant deformation due to reaching a very high temperature, so it is further confirmed whether the current pressure value of the cooking mechanism is equal to the target pressure value.

[0061] Step S42: In response to the current pressure value of the cooking device being equal to the target pressure value, obtaining a displacement signal output by the displacement detection member of the cooking device at the target pressure value.

[0062] Specifically, in response to the current pressure value of the cooking mechanism being equal to the target pressure value, a displacement signal output by the displacement detection member may be further obtained, that is, a displacement signal output by the displacement detection member at the target pressure value.

[0063] Step S43: In response to the current pressure value of the cooking device being not equal to the target pressure value, it is determined that the calibration has failed, and the first preset relationship is used as the cooking control information of the cooking device.

[0064] It should be noted that the first preset relationship is the correspondence between the pressure value within the cooking device and the displacement signal. Because there is a one-to-one correspondence between the pressure value within the cooking device and the displacement 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.

[0065] The beneficial effect of steps S41 to S43 is that when the timing duration is greater than the preset duration and the cooking temperature is less than or equal to the preset temperature, that is, the state of the displacement detection component is stable and the cooking equipment has not undergone significant deformation due to excessive temperature, it is further confirmed whether the current pressure value of the cooking equipment is the target pressure value. Only when the target pressure value is reached will the calibration control process be continued, thereby reducing the corresponding error between the target pressure value and the displacement signal output by the obtained displacement detection component caused by the error between the target pressure value and the current pressure value of the cooking equipment. Comprehensive consideration of the three perspectives of the timing duration after power-on, the cooking temperature, and the current pressure value of the cooking equipment to determine the timing of "obtaining the displacement signal output by the displacement detection component of the cooking equipment at the target pressure value" can effectively improve the accuracy of the calibration process, thereby improving the accuracy of the calibration results, and thereby improving the pressure control accuracy of the cooking equipment.

[0066] Optionally, this embodiment may further include step S34: in response to the cooking temperature being greater than the preset temperature, determining that the calibration has failed, and using the first preset relationship as cooking control information of the cooking device.

[0067] The beneficial effect of adding step S34 is that if the cooking temperature is greater than the preset temperature, it means that the cooking equipment may undergo significant deformation due to the high temperature, which will increase the detection error of the displacement signal, etc. By determining that the calibration has failed when the cooking temperature is greater than the preset temperature and using the first preset relationship as the cooking control information of the cooking equipment, the risk of invalid calibration can be reduced.

[0068] In other embodiments, step S11 can also be performed as follows: Figure 11 The method shown is implemented, that is, in response to the power-on instruction, directly determining the timing of "obtaining the displacement signal output by the displacement detection member of the cooking device at the target pressure value" based on the cooking temperature, specifically including steps S111 to S113:

[0069] Step S111: In response to the power-on instruction, the cooking temperature of the cooking device is obtained.

[0070] Step S112: In response to the cooking temperature being less than or equal to the preset temperature, obtaining a displacement signal output by the displacement detection member of the cooking device at a target pressure value.

[0071] The specific implementation of step S112 may refer to step S33 .

[0072] The beneficial effect of steps S111 to S112 is that, in response to a power-on instruction, the displacement signal output by the displacement detection member of the cooking device at the target pressure value is obtained only when the cooking temperature is less than or equal to the preset temperature, which can reduce the risk of the cooking device undergoing large deformation due to reaching a very high temperature, thereby improving the calibration accuracy of the calibration method.

[0073] Optionally, step S113: in response to the cooking temperature being greater than the preset temperature, determining that the calibration has failed, and using the first preset relationship as cooking control information of the cooking device.

[0074] The specific implementation of step S113 can refer to step S34 and will not be repeated here.

[0075] Of course, in other embodiments, step S11 can also be performed as follows: Figure 12 The method shown is implemented, that is, in response to the power-on instruction, directly determining the timing of "obtaining the displacement signal output by the displacement detection member of the cooking device at the target pressure value" based on the current pressure value of the cooking device, specifically including steps S121 to S123:

[0076] Step S121: In response to the power-on instruction, the current pressure value of the cooking device is obtained, and it is determined whether the current pressure value of the cooking device is equal to the target pressure value.

[0077] Specifically, in response to the power-on instruction, the current pressure value of the cooking device is automatically obtained and compared with the target pressure value of the cooking device. The specific setting method of the target pressure value can be found in step S11 and will not be repeated here.

[0078] Step S122: In response to the current pressure value of the cooking device being equal to the target pressure value, obtaining a displacement signal output by the displacement detection member of the cooking device at the target pressure value.

[0079] The specific implementation of step S122 can refer to step S42 and will not be repeated here.

[0080] The beneficial effect of step S121-step S122 is that, in response to the power-on instruction, the current pressure value of the cooking device is automatically obtained and compared with the current pressure value of the cooking device. Based on the comparison result, the timing of "obtaining the displacement signal output by the displacement detection member of the cooking device at the target pressure value" is determined. This can reduce the corresponding error between the target pressure value and the displacement signal output by the obtained displacement detection member caused by the error between the target pressure value and the current pressure value of the cooking device, thereby improving the calibration accuracy of the calibration method.

[0081] Optionally, step S123: in response to the current pressure value of the cooking device being not equal to the target pressure value, determining that the calibration has failed, and using the first preset relationship as cooking control information of the cooking device.

[0082] The specific implementation of step S123 can refer to step S43 and will not be repeated here.

[0083] Of course, in other embodiments, step S11 can also be performed as follows: Figure 13 The method shown is implemented, that is, in response to the power-on instruction, directly determining the timing of "obtaining the target pressure value of the cooking device and the displacement signal output by the displacement detection member at the target pressure value" based on the working information of the cooking device, specifically including steps S131 and S132:

[0084] Step S131: In response to the power-on instruction, determining the operating information of the cooking device.

[0085] Step S132: In response to the working information satisfying the preset condition, obtaining a displacement signal output by the displacement detection member of the cooking device at the target pressure value.

[0086] The working information meeting the preset conditions includes: the timing time after power-on is greater than the preset time, the cooking temperature of the cooking device is less than or equal to the preset temperature, and the current pressure value of the cooking device is equal to the target pressure value. At least any two of the following.

[0087] The beneficial effect of step S131-step S132 is that the working information meets the preset conditions, including the timing time after power-on is greater than the preset time, the cooking temperature of the cooking equipment is less than or equal to the preset temperature, and the current pressure value of the cooking equipment is equal to the target pressure value. At least two of the following can improve the flexibility of the calibration method, improve the adaptability to multiple scenarios and the calibration accuracy.

[0088] Step S12: obtaining a calibration value based on the first preset relationship, the target pressure value and the displacement signal.

[0089] Specifically, the target pressure value and the displacement signal can be substituted as known quantities into the first preset relationship to obtain a calibration value, wherein the displacement signal can be the frequency or pulse width of the signal, or other signal parameters.

[0090] Optionally, the first preset relationship is provided with a constant and an unknown quantity, and step S12 can be implemented by the method of step A21, specifically as follows:

[0091] Step A21: Substitute the target pressure value and the displacement signal as known quantities into the first preset relationship, and calculate the unknown quantity as a calibration value.

[0092] Substituting the target pressure value and the corresponding displacement signal as known quantities into the first preset relationship, the value of the unknown quantity can be obtained, and the value of the unknown quantity is the calibration value.

[0093] In this way, the calibration value can be calculated using the target pressure value and the corresponding displacement signal, which can improve the accuracy of the calibration value.

[0094] 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.

[0095] Since the correspondence between the pressure value in the cooking device and the displacement signal output by the displacement detection member depends on the state of the displacement detection member, there may be assembly errors during the production, assembly, or repair and reinstallation process of the cooking device, which may cause the initial state of the displacement detection member (for example, the initial position state of the displacement sensor) to have an error compared with the standard state; after the cooking device has been used for a period of time, the displacement detection member may age and deform, and the performance or structure may differ from the initial state; there may also be structural or performance errors between the multiple displacement detection members corresponding to the multiple cooking devices produced. These situations will cause the correspondence between the pressure value in the cooking device and the displacement signal output by the displacement detection member to change. Therefore, by setting a target pressure value, obtaining a corresponding displacement signal, and obtaining a calibration value based on the first preset relationship, the target pressure value, and the displacement signal, and using this calibration value to update the first preset relationship, a second preset relationship is obtained, that is, the second preset relationship is the preset relationship after calibration. The second preset relationship can more accurately reflect the correspondence between the pressure value in the cooking device and the displacement signal. Therefore, in subsequent use, the second preset relationship is used as cooking control information to control the operation of the cooking device, which can improve the pressure control accuracy.

[0096] The beneficial effect of steps S11 to S13 is that, in response to a trigger condition, the present embodiment can obtain a displacement signal output by the displacement detection element of the cooking device at a target pressure value, obtain a calibration value based on the first preset relationship, the target pressure value, and the displacement 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. Initiating calibration in response to a trigger condition allows the cooking device to automatically initiate calibration when a specific trigger condition is met, eliminating the need for the user to actively request calibration. This improves the self-detection capability of the cooking device, reduces the risk of failure, and enhances the pressure control accuracy of the cooking device. Furthermore, in this embodiment, the calibration value is obtained based on the first preset relationship, the target pressure value, and the displacement signal, and the calibration value is used to update the first preset relationship to obtain the second preset relationship. Using the second preset relationship as cooking control information for the cooking device allows the second preset relationship to more accurately reflect the correspondence between the pressure value and the displacement signal within the cooking device. This configuration can improve the accuracy of pressure detection and pressure control in the cooking device, thereby enhancing cooking results, improving product pressure control consistency, and enhancing the user experience. Therefore, this embodiment can improve the self-detection capability of the cooking equipment, reduce the failure risk of the cooking equipment, improve the pressure control accuracy of the cooking equipment, thereby improving the cooking effect, and can improve the consistency of product pressure control and improve the user experience.

[0097] Optionally, if the calibration fails, the calibration method may further include: determining that the calibration is abnormal and controlling the cooking device to alarm. The alarm may be in one or more forms such as a flashing display light, displaying characters, emitting an alarm sound, or other terminal message reminders.

[0098] Optionally, after calibration fails, the calibration method may further include prompting the user whether to perform maintenance. The prompting method is not limited to a specific method, and may include various methods such as a flashing display light. If the user chooses not to perform maintenance, the cooking device may continue to be controlled using the first preset relationship. If the user chooses to perform maintenance, the user may automatically report the problem via an internet connection or automatically initiate a maintenance appointment process via the cooking device or other associated terminal.

[0099] It should be noted that, before calibration begins, the pre-stored correspondence between the cooking device's pressure value and the displacement signal output by the detection element 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 a product is powered on for the first time, it can perform an automatic calibration control operation to obtain the second preset relationship, and then use the second preset relationship to control the cooking device in subsequent use. After the product is powered on a second time, it can perform another calibration control operation. During this calibration control process, the second preset relationship obtained at the end of the previous calibration will be stored and used as the first preset relationship in this calibration control process.

[0100] In other embodiments, similar improvements may be made to the calibration method, which will not be described in detail here.

[0101] This application further proposes a calibration method for cooking equipment, such as Figure 5 As shown, Figure 5 This is a flow chart of another embodiment of the calibration method for a cooking device of the present application. The cooking device of this embodiment includes: a cooking mechanism and a displacement detection member for measuring the displacement of the cooking mechanism. The calibration method of this embodiment specifically includes the following steps:

[0102] Step S51: acquiring a displacement signal output by a displacement detection member of the cooking device at a target pressure value in response to a trigger condition.

[0103] The specific implementation method can refer to the above step S11.

[0104] Step S52: obtaining a calibration value based on the first preset relationship, the target pressure value and the displacement signal.

[0105] The specific implementation method can refer to the above step S12.

[0106] Step S53: Compare the calibration value with the first calibration threshold.

[0107] 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 calibration value corresponding to the displacement signal output by the displacement detection element under the target pressure value condition during calibration. The first calibration threshold mainly depends on the performance of the displacement detection element. For example, when the displacement detection element is a displacement sensor, the first calibration threshold mainly depends on the limited range of the displacement sensor.

[0108] 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.

[0109] Among them, the first calibration threshold can be set as the lower limit of the range of effective calibration values ​​obtained according to the effective range of the displacement detection component when automatic calibration is performed under the target pressure value (that is, the atmospheric pressure value of the current environment). When the calibration value is less than the first calibration threshold, the calibration value is determined to be an abnormal calibration value. Therefore, if the calibration abnormality is confirmed, the first preset relationship is used as the cooking control information of the cooking equipment.

[0110] 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.

[0111] 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.

[0112] Optionally, the calibration method of this embodiment may further include step S55:

[0113] Step S55: 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.

[0114] 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 displacement signal allowed to be output by the displacement detection component. The calibration value is then used to update the first preset relationship to a second preset relationship, and the second preset relationship is used as the cooking control information of the cooking device.

[0115] 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.

[0116] In other embodiments, similar improvements can be made to the calibration method, which will not be described in detail here.

[0117] This application further proposes a calibration method for cooking equipment, such as Figure 6 As shown, Figure 6 This is a flow chart of another embodiment of the calibration method for a cooking device of the present application. The cooking device of this embodiment includes: a cooking mechanism and a displacement detection member for measuring the displacement of the cooking mechanism. The calibration method of this embodiment specifically includes the following steps:

[0118] Step S61: acquiring a displacement signal output by a displacement detection member of the cooking device at a target pressure value in response to a trigger condition.

[0119] The specific implementation method can refer to the above step S11.

[0120] Step S62: obtaining a calibration value based on the first preset relationship, the target pressure value, and the displacement signal.

[0121] The specific implementation method can refer to the above step S12.

[0122] Step S63: Compare the calibration value with the first calibration threshold.

[0123] For the specific implementation method, please refer to step S53 of the above embodiment.

[0124] Step S64: 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.

[0125] The specific implementation method can refer to step S54 of the above embodiment.

[0126] Step S65: 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.

[0127] 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 displacement signal allowed to be output by the displacement detection element when calibrating at the target pressure value. The upper limit mainly depends on the performance of the displacement detection element. For example, when the displacement detection element is a displacement sensor, the second calibration threshold mainly depends on the limited range of the displacement sensor.

[0128] Step S66: 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.

[0129] 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.

[0130] 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.

[0131] 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.

[0132] Optionally, the calibration method of this embodiment further includes step S67:

[0133] Step S67: 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.

[0134] 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 displacement signal output by the displacement 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.

[0135] 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.

[0136] For example, when the displacement detecting member is a displacement sensor, the first preset relationship is a linear relationship and satisfies the following relationship formula 1-1:

[0137] P=K+a……Relationship 1-1

[0138] 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.

[0139] 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 displacement signal Kp0 output by the displacement sensor under the pressure of 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. The second preset relationship is then used to control the operation of the cooking device.

[0140] P=K+(P0-Kp0)……Relationship 1-2

[0141] In other embodiments, similar improvements can be made to the calibration method, which will not be described in detail here.

[0142] The present application further proposes a cooking device. The cooking device of this embodiment includes a cooking mechanism, a displacement detection component, and a control mechanism. The displacement detection component is arranged on the cooking mechanism or in the cooking cavity of the cooking mechanism, and is used to measure the displacement of the cooking mechanism; the control mechanism is connected to the displacement detection component and the cooking mechanism, and is used to control the operation of the cooking device using the above-mentioned calibration method.

[0143] Alternatively, as Figure 9 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.

[0144] 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.

[0145] 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.

[0146] Optionally, the displacement detection member may include a displacement sensor, such as a potentiometer displacement sensor, a capacitive displacement sensor, or a linear displacement sensor, etc. The control mechanism may include a control chip, such as an MCU, etc., or a non-integrated circuit with control and data processing functions.

[0147] In one application scenario, the cooking mechanism includes a pot body and a pot lid. The displacement detection element can be disposed on the pot lid or the pot body. Furthermore, the cooking mechanism can also include an elastic diaphragm, which can be disposed on the pot body or the pot lid. The displacement detection element can measure the elastic deformation of the elastic diaphragm to detect the displacement, thereby outputting a displacement signal.

[0148] In one application scenario, when the displacement detection element is a displacement sensor, such as Figure 7 As shown in the figure, Q0, Q1, and Q2 respectively represent the displacement signal curves output by the displacement sensor in different initial positions. The horizontal axis represents the displacement signal, and the vertical axis represents the pressure value. For example, under a pressure of 0 kPa, when the displacement 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, and the second preset relationship is thus obtained. The relationship curve corresponding to the second preset relationship is Q0.

[0149] 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 displacement signal output corresponding to the effective range of the displacement sensor under different displacement input states; Kmax is the upper limit of the displacement 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。

[0150] The displacement signal can be expressed in the form of signal frequency, pulse width, etc.

[0151] In one application scenario, the cooking device is an electric pressure cooker, and the displacement detection element is a displacement sensor, such as Figure 8As shown, after the product is powered on, the timing unit starts timing and obtains the time t after power-on, that is, the timing duration t. When the timing duration t is less than or equal to the preset duration t0, the product continues to wait until the timing duration t is greater than the preset duration t0, and the cooking temperature T of the cooking device is obtained. If the cooking temperature T is greater than the preset temperature T0, it is determined that the calibration has failed, the pre-stored first preset relationship is obtained, the calibration is completed, and the first preset relationship is used to control subsequent operations of the cooking device; if the cooking temperature T is less than or equal to the preset temperature T0, it is determined whether the current pressure value of the cooking device is equal to the target pressure value, such as 0kPa. If not, it is determined that the calibration has failed, the pre-stored first preset relationship is obtained, the calibration is completed, and the first preset relationship is used to control subsequent operations of the cooking device; if it is determined that the current pressure value of the cooking device is equal to the target pressure value, such as 0kPa, the displacement signal Kp0 output by the displacement sensor at 0kPa is continued to be obtained, and the calibration value Kpx is obtained based on the first preset relationship, the target pressure value (for example, 0KPa) and the displacement signal Kp0, and the calibration value Kpx is compared with the first calibration threshold Kpmin comparison, in response to the calibration value Kpx being less than the first calibration threshold Kpmin, it can be prompted that the calibration failed, and the pre-stored first preset relationship is obtained. The calibration is completed and a calibration abnormality alarm is issued. The user can be prompted whether to perform maintenance. If so, the product is repaired. If otherwise, the first preset relationship is continued to be used to control the operation of the cooking device and perform cooking control; in response to the calibration value Kpx being greater than or equal to the first calibration threshold Kpmin, the calibration value Kpx is compared with the second calibration threshold Kpmax. In response to the calibration value Kpx being greater than the first calibration threshold Kpmax, it can be prompted that the calibration failed, and the pre-stored first preset relationship is obtained. The calibration is completed and a calibration abnormality alarm is issued. The user can be prompted whether to perform maintenance. If so, the product is repaired. If otherwise, the first preset relationship is continued to be used to control the operation of the cooking device and perform cooking control; in response to the calibration value Kpx being less than or equal to the first calibration threshold Kpmax, the calibration is successful, the first preset relationship is updated with the calibration value Kpx to obtain the second preset relationship, the calibration is completed and the second preset relationship is used to control the operation of the cooking device.

[0152] For example, the displacement detection element of an electric pressure cooker is a displacement sensor. Its internally stored first preset relationship satisfies Equation 1-1, with the pre-stored initial value of a being 0, the first calibration threshold being -5, and the second calibration threshold being 5. The target pressure is 0 kPa, the preset duration is 2 seconds, and the preset temperature is 50°C. When the corresponding product, Product 1, is powered on after production is complete and ready for shipment, 2 seconds later, the cooking temperature inside the cooker is less than 50°C, and the pressure inside the cooker is 0 kPa. The calibration method yields a calibration value of 1, resulting in the second preset relationship being Equation 2-1. Equation 2-1 is then used to control the operation of Product 1 in subsequent use.

[0153] P=K+1……Relationship 2-1

[0154] After product 1 leaves the factory, the user powers on the device when there is pressure in the pot. After 2 seconds, the cooking temperature in the pot is greater than 50°C. The calibration abnormality is confirmed and an alarm is triggered. The operation of product 1 is continued to be controlled using equation 2-1.

[0155] For another example, the displacement detection element of an electric pressure cooker is a displacement sensor. The first preset relationship stored in the sensor satisfies Equation 1-1, and the pre-stored initial value of a is 0, the first calibration threshold is -5, and the second calibration threshold is 5. The target pressure value is 0 kPa, the preset duration is 2 seconds, and the preset temperature is 50°C. The corresponding product 2 is powered on before production is completed and ready for shipment. After 2 seconds, the cooking temperature in the cooker is less than 50°C and the pressure in the cooker is 0 kPa. The calibration method obtains a calibration value of -1, and the second preset relationship is obtained as Equation 3-1 below. Equation 3-1 is then used to control the operation of product 2 in subsequent use.

[0156] P=K-1……Relationship 3-1

[0157] After Product 2 was used for a period of time after leaving the factory, the elastic diaphragm in the displacement sensor deformed due to long-term use. The user powered on the appliance with no pressure inside. Two seconds later, the cooking temperature inside the appliance was less than 50°C, and the pressure inside the appliance was 0 kPa. The calibration method yielded a value of 3, resulting in the second preset relationship, Equation 3-2. Equation 3-2 was subsequently used to control Product 2's operation. After continued use for a period of time, the elastic diaphragm in the displacement sensor severely deformed due to long-term use. The user powered on the appliance with no pressure inside the appliance. Two seconds later, the cooking temperature inside the appliance was less than 50°C, and the pressure inside the appliance was 0 kPa. The calibration method yielded a value of 6, exceeding the second calibration threshold. A calibration anomaly was confirmed, an alarm was triggered, and Equation 3-2 continued to be used to control Product 2's operation, prompting the user to request repairs.

[0158] P=K+3……Relationship 3-2

[0159] In other embodiments, similar improvements can be made to the cooking equipment, which will not be described in detail here.

[0160] This application further proposes a calibration method for cooking equipment, such as Figure 14 As shown, the calibration method of this embodiment specifically includes steps S141 to S144.

[0161] Step S141: acquiring a displacement signal output by a displacement detection member of the cooking device at a target pressure value in response to a trigger condition.

[0162] The specific implementation of step S141 can refer to step S11 and will not be repeated here.

[0163] Step S142: obtaining a calibration value based on the first preset relationship, the target pressure value, and the displacement signal.

[0164] The specific implementation of step S142 can refer to step S12 and will not be repeated here.

[0165] Step S143: 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.

[0166] The first calibration threshold is less than the second calibration threshold. The first and second calibration thresholds constitute a valid calibration value range. This range corresponds to the range of valid calibration values ​​allowed for the displacement detection element to output valid displacement signals when calibrating at the target pressure value. This range primarily depends on the performance of the displacement detection element. For example, when the displacement detection element is a displacement sensor, the range of valid displacement signals output by the displacement detection element primarily depends on the limited range of the displacement sensor. Therefore, the valid calibration value range primarily depends on the limited range of the displacement sensor. If the calibration value is not within the range 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.

[0167] 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.

[0168] Optionally, step S144: 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.

[0169] 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 displacement signal output by the displacement detection element" can be obtained, which can improve the accuracy of pressure detection of the cooking device during the cooking process.

[0170] In other embodiments, steps S143 and S144 may not be included. After executing step S142, 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 the 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.

[0171] In other embodiments, steps S143 and S144 may not be included. After executing step S142, 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 the 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.

[0172] This application further proposes a computer storage medium, such as Figure 10 As shown, Figure 10 The computer storage medium 100 stores program instructions 101, which are executed by a processor to implement the above calibration method.

[0173] 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.

[0174] The computer storage medium 100 in this embodiment can be, but is not limited to, a USB flash drive, an SD card, a PD optical drive, a mobile hard drive, a large-capacity floppy drive, a flash memory, a multimedia memory card, a server, and the like.

[0175] 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.

[0176] 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.

[0177] Unlike the prior art, the present invention can obtain a displacement signal output by a displacement detection element of a cooking device at a target pressure value in response to a trigger condition, obtain a calibration value based on a first preset relationship, the target pressure value, and the displacement 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. Calibration initiated in response to a trigger condition allows the cooking device to automatically initiate calibration when a specific trigger condition is met, eliminating the need for the user to proactively request calibration. This improves the cooking device's self-diagnosis capabilities, reduces the risk of failure, and enhances the pressure control accuracy of the cooking device. Furthermore, the present invention obtains a calibration value based on the first preset relationship, the target pressure value, and the displacement 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 second preset relationship more accurately reflects the correspondence between the pressure value and the displacement signal within the cooking device. This configuration improves the accuracy of pressure detection and pressure control in the cooking device, thereby enhancing cooking results, improving product pressure control consistency, and enhancing the user experience. Therefore, the present application can improve the self-detection capability of cooking equipment, reduce the risk of failure of cooking equipment, improve the pressure control accuracy of cooking equipment, thereby improving the cooking effect, and can improve the consistency of product pressure control and improve the user experience.

[0178] The above description is only an implementation method of the present application and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the description and drawings of this application, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
