[0026] 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.

[0027] 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.

[0028] 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.

[0029] This application first proposes a control method for a cooking device, such as Figures 1 to 3 As shown, Figure 1 This is a flow chart of an embodiment of a control method for a cooking device of the present application. Figure 2 yes Figure 1 A flow chart of an embodiment of step S13 in the embodiment, Figure 3 yes Figure 2 Schematic diagram of a flow chart of an embodiment of step S22 in the embodiment. The cooking device of this embodiment includes a cooking mechanism, which includes, for example, a pot, a lid, a heating mechanism (such as a heating plate), etc. The cooking mechanism of this embodiment also includes a displacement detection member for measuring the displacement of the cooking mechanism. The displacement detection member is disposed within the pot, the lid, the heating mechanism, or the cooking body of the pot. The displacement detection member is used to directly obtain the displacement of the pot, the lid, or the heating mechanism as the displacement 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.

[0030] 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; a displacement detection member 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. The control method of this embodiment specifically includes the following steps:

[0031] Step S11: In response to the cooking mechanism not entering the cooking state, obtaining a first displacement signal output by the displacement detecting member.

[0032] It should be noted that the "non-cooking state" refers to the state when the cooking function of the cooking device has not yet begun. For example, the device is only powered on but has not yet started any specific cooking operations such as heating, and the cooking mechanism is in a pressure-free state. The cooking state is entered when the cooking function is turned on, and exited when the cooking function is turned off or ended. When the cooking mechanism has not yet entered the cooking state, the first displacement signal output by the displacement detection element is obtained, i.e., the displacement signal output by the displacement detection element at the current moment is obtained, i.e., the displacement signal output by the displacement detection element when the cooking mechanism is in a pressure-free state is obtained.

[0033] Step S12: Determine the weight of the food in the cooking mechanism based on the first displacement signal.

[0034] Specifically, when the cooking mechanism is in a pressure-free state, a corresponding relationship exists between the weight of the food in the cooking mechanism and the displacement signal output by the displacement detection element, and this relationship is pre-stored in the cooking device. Specifically, this corresponding relationship can be stored as a formula or in the form of a program data table, for example, written into the control program as a program data table.

[0035] Before the cooking function begins, that is, before the cooking state is entered, the displacement signal output by the displacement detection element is obtained, and the weight of the ingredients within the cooking mechanism is determined based on a pre-stored correspondence between the weight of the ingredients within the cooking mechanism and the displacement signal output by the displacement detection element. This process can be implemented through a table lookup or formula calculation. For example, in response to the cooking mechanism not entering the cooking state, the first displacement signal output by the displacement detection element, which detects the displacement of the cooking mechanism, is obtained and converted to the weight of the ingredients within the cooking mechanism through a table lookup. This weight can be used in the cooking control process and can also be displayed or announced to the user to assist in cooking preparation.

[0036] In another embodiment, a correspondence between the sum of the weight of the ingredients in the cooking mechanism in a non-pressure state and the weight of the cooking mechanism and the displacement signal output by the displacement detection element may be pre-stored. Furthermore, the weight of the cooking mechanism may be pre-stored. After the total weight in the non-pressure state is determined based on the first displacement signal, the weight of the ingredients may be subtracted from the total weight to obtain the weight of the ingredients. For example, if the cooking mechanism is a pot, a correspondence between the total weight of the ingredients in the pot and the pot and the displacement signal output by the displacement detection element may be pre-stored.

[0037] Step S13: determining a preset relationship based on the first displacement signal.

[0038] In one application scenario, a cooking mechanism performs pressure-controlled cooking using a set of cooking parameters (which may include, for example, pressure-maintaining control parameters). The cooking parameters may be signal cooking parameters or pressure cooking parameters. Signal cooking parameters may be directly compared or calculated with the displacement signal output by the displacement detector, while pressure cooking parameters may be directly compared or calculated with the pressure value.

[0039] In one application scenario, when the parameter type of the cooking parameter is a signal cooking parameter, during the cooking process, the displacement signal output by the displacement detection element can reflect the pressure value change inside the cooking mechanism. Therefore, pressure-controlled cooking can be performed directly based on the displacement signal output by the displacement detection element and the signal cooking parameter. The preset relationship is the "correspondence between the displacement signal and the signal cooking parameter" determined based on the first displacement signal. Specifically, Figure 10 As shown, during the cooking process, pressure-controlled cooking can be performed based on the correspondence between the displacement signal and the signal cooking parameter. For example, when the displacement signal during the cooking process is greater than the pressure-holding control parameter (K0), the cooking mechanism is controlled to enter the pressure-holding phase. Therefore, it is not difficult to understand that there is a correspondence between the displacement signal and the signal cooking parameter. In this application scenario, for differentiation, this correspondence is referred to as the first initial relationship. This first initial relationship can be used to perform normal pressure control during the cooking process. Because ingredients need to be added to the pot before cooking, the weight of the ingredients causes the pot to displace. Based on this displacement, the displacement detector generates a first displacement signal. If, after entering the cooking process, subsequent pressure-controlled cooking is performed based on the first initial relationship in this application scenario, pressure control errors will occur, affecting the cooking effect. In this case, the first initial relationship can be updated based on the first displacement signal to obtain an updated "correspondence between the displacement signal and the signal cooking parameter." This updated correspondence is referred to as the first preset relationship. Pressure-controlled cooking can be performed based on this first preset relationship during the subsequent cooking process, thereby improving pressure control accuracy and enhancing cooking results.

[0040] In another application scenario, when the cooking parameter type is a pressure cooking parameter, the preset relationship is a "correspondence between the displacement signal and the pressure value within the cooking mechanism," determined based on the first displacement signal. This first displacement signal, acquired before the cooking mechanism enters the cooking state, can be used to eliminate the influence of external factors such as the weight of the ingredients in front of the cooking chamber, thereby obtaining a more accurate "correspondence between the displacement signal and the pressure value within the cooking mechanism." This correspondence can then be used for subsequent cooking control, improving the accuracy of the cooking equipment's pressure control and improving cooking results.

[0041] For example, in one application scenario, the cooking mechanism includes a pot, and a corresponding relationship exists between the displacement signal output by the displacement detection element and the pressure value within the pot. For the sake of distinction, this relationship can be referred to as the second initial relationship in this application scenario, and this second initial relationship can be used to perform normal pressure control during the cooking process. Because food ingredients need to be added to the pot before cooking, the weight of the food ingredients will cause the pot to displace. The displacement detection element can generate a first displacement signal based on this displacement, which will result in an error between the second initial relationship and the "corresponding relationship between the displacement signal output by the displacement detection element and the pressure value within the pot." That is, the second initial relationship is not accurate enough in expressing the "corresponding relationship between the displacement signal output by the displacement detection element and the pressure value within the pot." If subsequent pressure control cooking is still performed based on the second initial relationship, a pressure control error will occur, affecting the cooking effect. In this case, a more accurate "corresponding relationship between the displacement signal output by the displacement detection element and the pressure value within the pot" can be updated based on the first displacement signal. For the sake of distinction, this updated corresponding relationship is referred to as the second preset relationship. In the subsequent cooking process, pressure control cooking can be performed based on this second preset relationship, thereby improving pressure control accuracy and improving cooking results.

[0042] That is, in both of the above application scenarios, a preset relationship (such as the above first preset relationship or the second preset relationship) can be determined based on the first displacement signal to improve the pressure control accuracy.

[0043] Optionally, in some embodiments, the preset relationship is a "corresponding relationship between the displacement signal and the pressure value in the cooking mechanism" determined based on the first displacement signal (such as the second preset relationship in the above embodiment), so step S13 can be performed as follows: Figure 2 The method shown is implemented, specifically including steps S21 to S22.

[0044] Step S21: obtaining an initial relationship between a displacement signal output by a preset displacement detection element and a pressure value of a cooking mechanism.

[0045] In this embodiment, the initial relationship is the correspondence between the displacement signal output by the preset displacement detection member and the pressure value of the cooking mechanism. When there is no food in the cooking mechanism, the correspondence between the displacement signal output by the displacement detection member and the pressure value of the cooking mechanism is obtained and stored as the initial relationship in the cooking device. It can be pre-stored in the form of a formula or in the form of a data table.

[0046] Step S22: determining a preset relationship based on the first displacement signal and the initial relationship.

[0047] In this embodiment, the preset relationship is the "correspondence between the displacement signal and the pressure value in the cooking mechanism" determined based on the first displacement signal. Based on the first displacement signal and the pre-stored initial relationship, the first displacement signal can be used to update the initial relationship to obtain the preset relationship. The first displacement signal is the displacement signal output by the displacement detection member when the cooking state has not been entered. The displacement signal output by the displacement detection member will be affected by the weight of the food inside the cooking mechanism. By using the first displacement signal to update the initial relationship, the influence of the weight of the food on the displacement signal can be taken into account to obtain a more accurate "correspondence between the displacement signal output by the displacement detection member and the pressure value in the cooking mechanism". This relationship is used as a preset relationship for cooking control in subsequent cooking processes, which can improve the accuracy of pressure control of the cooking equipment and the cooking effect.

[0048] Optionally, step S22 can be performed as follows: Figure 3 The method shown is implemented, specifically including steps S31 to S33.

[0049] Step S31: obtaining a third displacement signal corresponding to a zero pressure value based on the initial relationship.

[0050] Specifically, the initial relationship is a correspondence between a displacement signal output by a preset displacement detection member and a pressure value of the cooking mechanism, and a zero pressure value is substituted into the initial relationship to obtain a third displacement signal.

[0051] Step S32: Obtain the difference between the first displacement signal and the third displacement signal.

[0052] Specifically, the difference between the first displacement signal and the third displacement signal is calculated, for example, the first displacement signal is subtracted from the third displacement signal to obtain an increment of the displacement signal, that is, the difference.

[0053] Step S33: Using the difference as an increment of the displacement signal to compensate the initial relationship to obtain a preset relationship.

[0054] Specifically, the difference is used as an increment of the displacement signal to compensate for the initial relationship, that is, the initial relationship is updated, and a more accurate "correspondence between the displacement signal and the pressure value in the cooking mechanism" can be obtained. It should be noted that this correspondence can be a relational expression or a corresponding data table.

[0055] For example, in one application scenario, the displacement signal is K and the pressure value in the cooking mechanism is P. If the relationship between the displacement signal output by the displacement detection element and the pressure value satisfies the following equation 1-1, where a and b are relationship coefficients, and the initial relationship pre-stored in the cooking device satisfies the following equation 1-2, where a=2 and b=2. After the cooking device is powered on, in response to the cooking mechanism not entering the cooking state, a first displacement signal is acquired. If there is food in the cooking device, the acquired first displacement signal is 3. Substituting the zero pressure value into the initial relationship yields a third displacement signal of -1. The difference between the first and third displacement signals is calculated to be -4, where -4 is the increment of the displacement signal. Compensating -4 into the initial relationship yields equation 1-3, which is simplified to equation 1-4. This yields the corresponding relationship between the displacement signal output by the displacement detection element and the pressure value in the cooking mechanism. It can be found that in equation 1-4, when K=3, P=0, i.e., the displacement signal corresponds to the pressure value. This relationship can be used as a preset relationship for cooking control in subsequent cooking processes, which can improve the accuracy of pressure control of cooking equipment and cooking effects.

[0056] P=aK+b……Relationship 1-1

[0057] P=2K+2……Relationship 1-2

[0058] P=2(K-4)+2……Relationship 1-3

[0059] P=2K-6……Relationship 1-4

[0060] The setting of steps S31 to S33 can use the first displacement signal and the initial relationship to obtain a more accurate "correspondence between the displacement signal output by the displacement detection component and the pressure value inside the cooking mechanism", that is, the preset relationship, and this calculation method can improve the accuracy of the preset relationship obtained, thereby improving the accuracy of the pressure control of the cooking equipment and the cooking effect.

[0061] In other embodiments, similar improvements may be made to the control method of the cooking device, which will not be described in detail here.

[0062] The configuration of steps S21 and S22 can improve the convenience and accuracy of determining the preset relationship based on the first displacement signal. Since the displacement detection member outputs a displacement signal, directly obtaining the initial relationship between the displacement signal output by the preset displacement detection member and the pressure value can reduce the calculation process in the control method and eliminate the need for multiple conversions and correspondences between the displacement signal, displacement amount, and pressure value. This can reduce the risk of calculation errors and thus improve the accuracy of the control method of this embodiment. Moreover, when the cooking state is not entered, the first displacement signal is used to correct the initial relationship to obtain the preset relationship under no pressure conditions and with the weight of the food. This can more accurately take into account the influence of the weight of the food on the preset relationship, and can obtain a more accurate preset relationship, that is, a more accurate correspondence between the pressure value in the cooking mechanism and the displacement signal can be obtained, which can improve the accuracy of the pressure control of the cooking equipment and the cooking effect.

[0063] In other embodiments, similar improvements may be made to the control method of the cooking device, which will not be described in detail here.

[0064] In other embodiments, step S13 may be implemented in other ways. For example, a preset initial relationship between the displacement of the cooking mechanism and the pressure value within the cooking mechanism, obtained based on the displacement signal output by the displacement detection element, may be obtained; and the preset relationship may be determined based on the first displacement signal and the initial relationship. In this case, the preset relationship may also be a corresponding relationship between the displacement of the cooking mechanism during the cooking state and the pressure value within the cooking mechanism. The initial relationship may be updated based on the first displacement signal to obtain the preset relationship.

[0065] Step S14: in response to the cooking mechanism entering the cooking state, obtaining a second displacement signal output by the displacement detecting member.

[0066] Specifically, the cooking function is turned on and the cooking mechanism enters the cooking state. The second displacement signal is the displacement signal output by the displacement detection element in the cooking state.

[0067] Step S15: Controlling the cooking mechanism based on the weight, the preset relationship and the second displacement signal.

[0068] In an application scenario, such as Figure 9 、 Figure 10 As shown, the cooking mechanism performs pressure-controlled cooking using a set of cooking parameters (which may include, for example, pressure-maintaining control parameters). Different sets of cooking parameters can be assigned to ingredients of varying weights. The corresponding cooking parameters can be derived based on the weights. The pressure within the cooking mechanism is controlled based on the second displacement signal, the cooking parameters, and a predetermined relationship (such as the first or second predetermined relationship in the aforementioned embodiment), allowing the cooking mechanism to complete the cooking control process based on the cooking parameters.

[0069] In one application scenario, the cooking mechanism includes a pressure cooker and a hot plate, and the displacement detection component is a high-precision displacement sensor. Before the pressure cooker is heated and pressurized, that is, before entering the cooking state, the gravity exerted by the weight of the pressure cooker and the food in the pot will cause the hot plate to displace. The displacement sensor detects a displacement amount and outputs a displacement signal, namely, a first displacement signal; after the pressure cooker is heated and pressurized, the pressure generated by the air pressure in the pot will also cause the hot plate to further displace. The displacement sensor detects the new displacement amount and outputs a displacement signal, namely, a second displacement signal. Therefore, by collecting displacement at different stages to generate displacement signals at different stages, not only can the weight of the food be determined, but the initial relationship can also be updated using the first displacement signal, resulting in a more accurate "correspondence between the pressure value inside the pressure cooker and the displacement signal," i.e., a preset relationship. The second displacement signal, the weight of the food, and this preset relationship can then be used to control the cooking mechanism, improving pressure control accuracy and enhancing cooking results. Furthermore, the use of a high-precision displacement sensor not only determines the weight of the food but also enables pressure control, eliminating the need for a pressure switch and an additional weight sensor. While traditional weight sensors are only used for weighing, the displacement sensor in this application scenario is positioned below the hot plate. The collected displacement can be converted into weight or pressure data, reducing costs and improving control accuracy and ease of manufacturing and assembly. For example, the change in displacement can be converted into a change in inductance or capacitance, which can then be converted into frequency or voltage data using a corresponding LC or RC resonant circuit to output a displacement signal. The pressure cooker's main control chip can then use this displacement signal to determine the change in the hot plate's displacement, which can then be used for weighing or pressure control.

[0070] The arrangement of steps S11 to S15 can obtain the first displacement signal before the cooking mechanism enters the cooking state, and determine the weight of the food according to the first displacement signal, thereby realizing a more accurate weighing function. Therefore, it is convenient to control the operation of the cooking mechanism based on the weight of the food in the subsequent cooking control process, thereby improving the cooking control effect. Moreover, the first displacement signal corresponding to the weight of the food is obtained, and a preset relationship is determined based on the first displacement signal, which can improve the accuracy of "the correspondence between the displacement signal output by the displacement detection member and the pressure value in the cooking mechanism" or "the correspondence between the displacement signal output by the displacement detection member and the cooking parameter of the cooking mechanism", that is, it can improve the pressure control accuracy of the subsequent cooking control and improve the cooking effect. Moreover, the operation of the cooking mechanism is controlled based on the weight, the preset relationship and multiple reference angles of the second displacement signal, which can further improve the accuracy of the cooking control, improve the pressure control accuracy of the cooking mechanism and improve the cooking effect. Moreover, this method can reduce the pressure switch pressure control components or additional weight sensors, thereby reducing costs and improving the convenience of manufacturing and assembly.

[0071] In other embodiments, in addition to referring to the weight, the preset relationship, and the second displacement signal, the cooking function selected by the user or the holding pressure value or the holding pressure time may also be referred to to control the operation of the cooking mechanism.

[0072] In other embodiments, the control method may further include steps A1 and A2 before step S15, and step S15 may be implemented via step A3. The cooking device further includes a temperature detector for measuring the temperature of the cooking mechanism. In this embodiment, the preset relationship is a correspondence between the displacement signal output by the displacement detector and the pressure value within the cooking mechanism. The temperature detector is disposed within the pot, lid, heating mechanism, or cooking body of the cooking mechanism and is used to directly obtain the temperature of the pot, lid, heating mechanism, or cooking body of the pot as the temperature value of the cooking mechanism.

[0073] Step A1: In response to the cooking mechanism entering a cooking state and the cooking mechanism generating a first displacement, a temperature value of the cooking mechanism output by a temperature detecting element is obtained as a pressure starting temperature of the cooking mechanism.

[0074] The cooking mechanism generates its first displacement, which indicates the cooking mechanism begins to generate pressure. At this point, the pressure within the cooking mechanism approaches the atmospheric pressure of the cooking device. Alternatively, the timing of "the cooking mechanism generating its first displacement" can be determined based on the timing of "the displacement detection member detecting the cooking mechanism generating its first displacement."

[0075] Among them, the pressure starting temperature of the cooking mechanism can be obtained by obtaining the temperature value output by the temperature detection component when the pressure starts; in other embodiments, the pressure starting temperature of the cooking mechanism can also be obtained by calculating the average temperature. Specifically, when the pressure starts, multiple temperature values ​​of the temperature detection component within a preset time period are obtained and the average temperature value is calculated as the pressure starting temperature.

[0076] In one application scenario, starting from before the pressure starts (for example, starting from the moment when the cooking mechanism enters the cooking state), the temperature detection element regularly outputs the temperature of the cooking mechanism and stores it in the cooking equipment in sequence. When the cooking mechanism starts to start pressure, all temperature values ​​output by the temperature detection element in the time period from moment T1 before the pressure starts to moment T2 after the pressure starts can be obtained, and their average value can be calculated to obtain the pressure start temperature; in another application scenario, all temperature values ​​output by the temperature detection element in the time period from the start of pressure to moment T3 after the pressure starts can be obtained, and their average value can be calculated to obtain the pressure start temperature.

[0077] Step A2: Determine the altitude of the environment in which the cooking device is located based on the pressure starting temperature, the corresponding relationship between the pressure starting temperature and the boiling point, and the corresponding relationship between the boiling point and the altitude.

[0078] In some application scenarios, the cooking mechanism includes an inner pot and a lid. Due to the influence of factors such as the lid, the pressure-starting temperature of the inner pot is not completely consistent with the natural boiling point of the environment in which the cooking equipment is located. There is a corresponding relationship between the pressure-starting temperature and the boiling point. Based on the corresponding relationship between the pressure-starting temperature and the boiling point, the natural boiling point of the environment in which the cooking equipment is located is obtained, and then based on the corresponding relationship between the boiling point and the altitude, the altitude of the environment in which the cooking equipment is located is obtained.

[0079] The correspondence between the pressure initiation temperature and the boiling point can be obtained by adding a compensation value to the pressure initiation temperature to obtain the natural boiling point (i.e., boiling point) of the cooking device's environment. In one application scenario, the pressure initiation temperature and the natural boiling point of the cooking device's environment have a linear correspondence. The correspondence between the pressure initiation temperature and the boiling point, and the correspondence between the boiling point and the altitude, can be pre-stored in the cooking device, for example, in the cooking device's control chip.

[0080] The pressure starting temperature is obtained based on the timing when the displacement detection part detects the "first displacement of the cooking mechanism", and the boiling point is calculated using the correspondence between the pressure starting temperature and the boiling point. This can improve the accuracy of the judgment of the pressure starting timing, and thus improve the accuracy of the judgment of the boiling point.

[0081] Step A3: Controlling the operation of the cooking mechanism based on the weight, the preset relationship, the second displacement signal, and the altitude.

[0082] In one application scenario, a cooking mechanism uses a set of cooking parameters (which may include pressure-maintaining control parameters) to perform pressure-controlled cooking. Because ambient atmospheric pressure varies at different altitudes, setting different cooking parameters for different altitudes can improve cooking results. For example, a pre-stored relationship between altitude and cooking compensation parameters can be used to determine the cooking compensation parameters based on the altitude, and then compensate for the cooking parameters using the cooking compensation parameters.

[0083] In one application scenario, the preset relationship is the correspondence between the displacement signal output by the displacement detection element and the pressure value in the cooking mechanism. The cooking parameters are obtained based on the weight of the ingredients. The normal operation of the cooking mechanism in the cooking state is controlled based on the preset relationship and the second displacement signal. After the cooking equipment is pressurized, the corresponding cooking compensation parameters can be obtained based on the altitude. The cooking parameters can be compensated to more accurately control the subsequent pressure-controlled cooking stage to improve the cooking effect.

[0084] Optionally, the cooking compensation parameters may be obtained only when the cooking device performs cooking for the first time, and the cooking compensation parameters may be used in subsequent cooking operations, and the compensation adjustment of the cooking parameters may be completed directly when cooking begins.

[0085] Of course, in other embodiments, step A1 can also be implemented by "responding to the cooking mechanism entering the cooking state, the altitude compensation instruction and the cooking mechanism generating the first displacement, obtaining the temperature of the cooking mechanism output by the temperature detection component as the starting pressure temperature of the cooking mechanism", wherein the altitude compensation instruction can be generated based on the user's key operation, etc., which can improve the user's convenience; or the cooking device can obtain a processing result after comprehensive processing based on environmental, time and other information, and generate an altitude compensation instruction based on this processing result, which can improve the automation of the cooking device.

[0086] The beneficial effect of the above setting is that by adjusting the cooking parameters of the cooking device according to the altitude, the cooking effect of the cooking device can be further improved and the multi-scenario applicability of the cooking device can be improved.

[0087] In other embodiments, similar improvements can be made to the control method, which will not be described in detail here.

[0088] This application further proposes a control method for a cooking device, such as Figure 4 As shown, Figure 4 1 is a flow chart of another embodiment of a control 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 control method of this embodiment specifically includes the following steps:

[0089] Step S41: In response to the cooking mechanism not entering the cooking state, obtaining a first displacement signal output by the displacement detecting member.

[0090] For a specific implementation, please refer to the above step S11.

[0091] Step S42: Obtaining the total weight based on the first displacement signal.

[0092] In one application scenario, the total gravity exerted by the total weight of the cooking mechanism and the ingredients in the cooking mechanism will cause the detection end of the displacement detection element to displace, thereby outputting a first displacement signal. Therefore, the total weight can be obtained based on the correspondence between the total weight of the ingredients in the cooking mechanism and the cooking mechanism in a pre-stored pressure-free state and the displacement signal output by the displacement detection element.

[0093] Step S43: Obtain the weight of the food in the cooking mechanism based on the gross weight and the net weight of the cooking mechanism.

[0094] Specifically, the net weight of the cooking mechanism may be pre-stored in the cooking device. The weight of the ingredients in the cooking mechanism may be obtained by subtracting the net weight of the cooking mechanism from the total weight.

[0095] Step S44: determining a preset relationship based on the first displacement signal.

[0096] For a specific implementation, please refer to the above step S13.

[0097] Step S45: in response to the cooking mechanism entering the cooking state, obtaining a second displacement signal output by the displacement detecting member.

[0098] For a specific implementation, please refer to the above step S14.

[0099] Step S46: Controlling the cooking mechanism based on the weight, the preset relationship and the second displacement signal.

[0100] For a specific implementation, please refer to the above step S15.

[0101] The beneficial effect of this embodiment is that by pre-storing the correspondence between the total weight of the cooking mechanism and the ingredients in the cooking mechanism in a pressure-free state and the displacement signal output by the displacement detection component, and pre-storing the net weight of the cooking mechanism, the total weight can be obtained using the first displacement signal, and the weight of the ingredients can be obtained by subtracting the net weight from the total weight. This method is simple to calculate and has a low risk of error, which can improve the accuracy of calculating the weight of the ingredients, thereby improving the accuracy of cooking control and improving the cooking effect.

[0102] In other embodiments, the correspondence between the total weight of the cooking mechanism and the ingredients in the cooking mechanism in a pressure-free state and the displacement of the cooking mechanism can be pre-stored. The displacement of the cooking mechanism can be obtained by obtaining the first displacement signal output by the displacement detection component, and the total weight can be obtained using the above correspondence.

[0103] In other embodiments, similar improvements may be made to the control method of the cooking device, which will not be described in detail here.

[0104] This application further proposes a control method for a cooking device, such as Figure 5 and Figure 6 As shown, Figure 5 This is a flow chart of another embodiment of the control method of the cooking device of the present application. Figure 6 yes Figure 5 Flowchart of step S57 in the embodiment. The cooking device of the embodiment includes a cooking mechanism and a displacement detection member for measuring the displacement of the cooking mechanism. The control method of the embodiment specifically includes the following steps:

[0105] Step S51: In response to the cooking mechanism not entering the cooking state, obtaining a first displacement signal output by the displacement detection member at least at the previous moment and the current moment.

[0106] Specifically, when the cooking mechanism is not in the cooking state, at least the first displacement signal at the previous moment and the first displacement signal at the current moment are obtained. For example, first displacement signals corresponding to multiple moments when the cooking mechanism is not in the cooking state may also be obtained.

[0107] Step S52: Obtaining the total weight based on the first displacement signal.

[0108] Specifically, each time a first displacement signal is obtained, a corresponding total weight value is obtained. For example, at least the total weight corresponding to the first displacement signal at the previous moment and the total weight corresponding to the first displacement signal at the current moment can be obtained. For the specific implementation method of obtaining the total weight based on the first displacement signal, please refer to the above step S42.

[0109] Step S53: Determine whether the total weight has increased based on the total weight corresponding to the previous moment and the total weight corresponding to the current moment.

[0110] By comparing the total weight corresponding to the previous moment with the total weight corresponding to the current moment, it is possible to confirm whether the total weight has increased.

[0111] In other embodiments, whether the total weight has changed may also be confirmed by the size relationship between different total weights corresponding to different moments.

[0112] Step S54: In response to the total weight not increasing, obtaining the weight of the food in the cooking mechanism based on the total weight and the net weight of the cooking mechanism.

[0113] Specifically, when the judgment result is that the total weight has not increased, since the total weight is the total weight of the ingredients and the cooking mechanism, and since the net weight of the cooking mechanism has been pre-stored, the weight of the ingredients can be obtained by subtracting the net weight from the total weight.

[0114] In other embodiments, the step of obtaining the weight of the ingredients in the cooking mechanism based on the total weight and the net weight of the cooking mechanism may be performed in response to the total weight not changing, for example, in response to the total weight not increasing or decreasing.

[0115] Step S55: determining a preset relationship based on the first displacement signal.

[0116] For a specific implementation, please refer to the above step S44.

[0117] Step S56: In response to the cooking mechanism entering the cooking state, obtaining a second displacement signal output by the displacement detection member.

[0118] For a specific implementation, please refer to the above step S45.

[0119] Step S57: Controlling the cooking mechanism based on the weight, the preset relationship and the second displacement signal.

[0120] For a specific implementation, please refer to the above step S46.

[0121] Alternatively, step S57 can be performed as follows Figure 6 The method shown is implemented, specifically including step S61 and step S62.

[0122] Step S61: Determine cooking parameters based on weight.

[0123] Specifically, the mapping between ingredient weight and cooking parameters is pre-stored within the cooking device. Cooking parameters can include parameters controlling heating time or pressure within the cooking mechanism. For example, cooking parameters can include heating power and heating time. Different heating powers and corresponding heating times can be matched based on ingredient weight. It should be noted that each ingredient weight can correspond to a set of heating powers and heating times. For example, after heating for a first duration at power Pw1, heating for a second duration at power Pw2 can be performed.

[0124] Step S62: Controlling the cooking mechanism based on the cooking parameters, the preset relationship and the second displacement signal.

[0125] In some embodiments, cooking parameters include heating power and corresponding heating time. Cooking parameters may also include maximum and minimum pressure alarm control parameters, specifically pressure cooking parameters. The preset relationship is a "correspondence between the displacement signal and the pressure value within the cooking mechanism," determined based on the first displacement signal. The pressure value within the cooking mechanism can be determined using the second displacement signal and the preset relationship. When the pressure value exceeds the range of the maximum and minimum pressure alarm control parameters, the cooking mechanism can be controlled to stop heating and issue an alarm, thereby improving both cooking control accuracy and user safety.

[0126] Specifically, in an application scenario, such as Figure 9 As shown, cooking parameters include preheating power, holding power, and a corresponding set of pressure cooking parameters. The pressure cooking parameters include a holding control parameter (P0), a first heating control parameter (PL), a second heating control parameter (PH), a first alarm control parameter (Pmin), and a second alarm control parameter (Pmax). The first alarm control parameter is less than the first heating control parameter, the first heating control parameter is less than the second heating control parameter, and the second heating control parameter is less than the second alarm control parameter. Cooking parameters also include a maximum preheating time t0 and a holding time T. Specifically, when cooking is initiated, the cooking mechanism enters the preheating phase and begins heating at the preheating power. The pressure value (P) within the cooking mechanism is determined using the second displacement signal and a preset relationship. When the pressure value (P) within the cooking mechanism reaches the holding control parameter (P0), the cooking mechanism is controlled to enter the holding phase. If the pressure value within the cooking mechanism does not reach the holding control parameter (P0), it is determined whether the preheating phase operating time t1 has reached the maximum preheating time t0. If so, the pressure holding phase is entered; if not, heating continues.

[0127] During the pressure holding stage, the total working time t2 of the cooking mechanism during the pressure holding stage is obtained. If t2 is greater than or equal to the pressure holding time, heating is stopped and cooking is ended; if t2 is less than the pressure holding time, the pressure value in the cooking mechanism is compared with the first alarm control parameter (Pmin); when the pressure value in the cooking mechanism is less than or equal to the first alarm control parameter (Pmin), heating is stopped and an alarm is issued; when the pressure value in the cooking mechanism is greater than or equal to the first alarm control parameter (Pmin), it is determined whether the pressure value in the cooking mechanism is greater than the first heating control parameter (PL).

[0128] Furthermore, if the pressure value in the cooking mechanism is less than the first heating control parameter (PL), heating is continued with the pressure-maintaining heating power, and the pressure value in the cooking mechanism is compared with the second alarm control parameter; and when the pressure value in the cooking mechanism is greater than or equal to the first heating control parameter (PL), the pressure value in the cooking mechanism is directly compared with the second alarm control parameter (Pmax).

[0129] Furthermore, if the pressure value in the cooking mechanism is less than or equal to the second alarm control parameter (Pmax), the pressure value in the cooking mechanism is compared with the second heating control parameter (PH); and when the pressure value in the cooking mechanism is greater than the second alarm control parameter (Pmax), heating is stopped and an alarm is issued.

[0130] Furthermore, if the pressure value within the cooking mechanism is less than or equal to the second heating control parameter (PH), the total operating time t2 of the pressure holding phase is compared with the pressure holding time T. If t2 is greater than or equal to the pressure holding time T, heating is stopped and cooking is completed. If the pressure value within the cooking mechanism is greater than the second heating control parameter (PH), heating is stopped and the total operating time t2 of the pressure holding phase is compared with the pressure holding time T. If t2 is greater than or equal to the pressure holding time T, heating is stopped and cooking is completed. If t2 is less than the pressure holding time T, the above steps are repeated. The alarm method may be voice or display, etc., and is not specifically limited.

[0131] For another example, in another application scenario, the cooking parameters include heating power and a corresponding set of signal cooking parameters. The preset relationship is the "correspondence between the displacement signal and the signal cooking parameters" determined based on the first displacement signal. The signal cooking parameters include a pressure holding control parameter (K0), a first heating control parameter (KL), a second heating control parameter (KH), a first alarm control parameter (Kmin), and a second alarm control parameter (Kmax). The first alarm control parameter is less than the first heating control parameter, the first heating control parameter is less than the second heating control parameter, and the second heating control parameter is less than the second alarm control parameter. The cooking parameters also include a maximum preheating time t0 and a pressure holding time T. The corresponding signal cooking parameters can be obtained using the preset relationship, and the cooking mechanism can be controlled based on the second displacement signal and the signal cooking parameters.

[0132] Specifically, in another application scenario, such as Figure 10 As shown, after cooking is initiated, the cooking mechanism enters the preheating phase and begins heating. When the second displacement signal (K) is greater than or equal to the pressure-maintaining control parameter (K0), the cooking mechanism is controlled to enter the pressure-maintaining phase. Conversely, if the second displacement signal (K) is less than the pressure-maintaining control parameter (K0), the cooking mechanism is controlled to continue heating and obtain the total operating time t1 during the preheating phase, i.e., the first operating time t1. In response to the first operating time t1 being greater than the preset maximum heating time t0 for the preheating phase, the cooking mechanism is controlled to enter the pressure-maintaining phase. Otherwise, the second displacement signal (K) is continuously obtained and compared with the pressure-maintaining control parameter (K0).

[0133] During the pressure-holding stage, the total working time t2 of the cooking mechanism during the pressure-holding stage, that is, the second working time t2, is obtained. If t2 is less than the pressure-holding time T set by the user, the second displacement signal (K) is obtained and compared with the first alarm control parameter (Kmin); when the second displacement signal (K) is less than the first alarm control parameter (Kmin), heating is stopped and an alarm is issued; when the second displacement signal (K) is greater than or equal to the first alarm control parameter (Kmin), the second displacement signal (K) is compared with the first heating control parameter (KL).

[0134] Furthermore, if the second displacement signal (K) is less than the first heating control parameter (KL), the cooking mechanism is controlled to continue heating, and the second displacement signal (K) and the second alarm control parameter (Kmax) are continuously acquired and compared; when the second displacement signal (K) is greater than or equal to the first heating control parameter (KL), the second displacement signal (K) is directly compared with the second alarm control parameter (Kmax).

[0135] Furthermore, when the second displacement signal (K) is less than or equal to the second alarm control parameter (Kmax), the second displacement signal (K) is compared with the second heating control parameter (KH); and when the second displacement signal (K) is greater than the second alarm control parameter (Kmax), heating is stopped and an alarm is issued.

[0136] Furthermore, when the second displacement signal (K) is less than or equal to the second heating control parameter (KH), the second working time t2 is compared with the holding time (T) set by the user; when the displacement signal K is greater than the second heating control parameter (KH), heating is stopped, and the second working time t2 is compared with the holding time (T) set by the user.

[0137] Furthermore, in response to the second operating time t2 being greater than or equal to the pressure holding time (T) set by the user, the cooking mechanism is controlled to stop operating, and cooking ends; and when t2 is less than the pressure holding time T, the above steps are repeated. The alarm method may be voice or information display, etc., and is not specifically limited.

[0138] In other embodiments, the cooking parameters may also be a combination of more parameter types. The above is for illustration only and is not intended to be limiting.

[0139] Optionally, the cooking parameters include at least one of heating power and heating time.

[0140] Specifically, the cooking parameters include at least one of heating power and heating duration, thereby improving the accuracy of controlling the internal pressure of the cooking mechanism, thereby improving the accuracy of controlling the cooking process and enhancing cooking safety. For example, if the cooking parameters include at least heating power, the pressure value within the cooking mechanism is determined based on a preset relationship and the second displacement signal, and the cooking mechanism is controlled to heat at a specific heating power. Heating is stopped when the pressure value within the cooking mechanism reaches a user-set holding pressure value.

[0141] In other embodiments, similar improvements may be made to the control method of the cooking device, which will not be described in detail here.

[0142] The beneficial effect of step S61 and step S62 is that determining cooking parameters based on the weight of ingredients can improve the cooking mechanism's ability to adapt to different cooking scenarios, thereby improving the accuracy of the cooking mechanism's cooking control, improving the cooking effect of the cooking mechanism, and improving the user experience.

[0143] In other embodiments, in addition to determining cooking parameters based on weight and controlling the cooking mechanism based on the cooking parameters, the preset relationship, and the second displacement signal, step S57 may be implemented in other ways. For example, the cooking parameters may be determined based on a user-set holding pressure value and holding time, adjusted based on the weight of the ingredients, and then the cooking mechanism may be controlled based on the cooking parameters, the preset relationship, and the second displacement signal. In another example, the cooking parameters may be determined based on a user-set holding pressure value and holding time, further adjusted based on a user-selected cooking function and the weight of the ingredients, and then the cooking mechanism may be controlled based on the cooking parameters, the preset relationship, and the second displacement signal.

[0144] In other embodiments, similar improvements may be made to the control method of the cooking device, which will not be described in detail here.

[0145] The beneficial effect of steps S51 to S57 is that by confirming whether the total weight has increased, and based on the total weight no longer increasing, the step of obtaining the weight of the ingredients in the cooking mechanism based on the total weight and the net weight of the cooking mechanism is executed. This method can reconfirm the total weight when the total weight has not increased, which can improve the accuracy of the weight of the obtained ingredients and reduce the risk of errors; and based on the total weight corresponding to the previous moment and the total weight corresponding to the current moment, it is determined whether the total weight has increased. In this way, it is possible to judge whether the total weight has increased based on the user usage scenario, which can improve the accuracy of the judgment on whether the total weight has increased, and thus improve the accuracy of the weight of the obtained ingredients; and at least the first displacement signal output by the displacement detection element is obtained at the previous moment and the current moment respectively. In this way, the total weight at different moments is confirmed, which can improve the detection accuracy of the total weight, and thus improve the detection accuracy of the total weight change, and thus improve the accuracy of the judgment on whether the total weight has increased, which can improve the accuracy of the weight of the obtained ingredients, improve the accuracy of subsequent cooking control, and thus improve the cooking effect.

[0146] Optionally, the control method of this embodiment further includes step S58:

[0147] Step S58: In response to the total weight increasing, repeatedly acquiring the first displacement signal and repeatedly determining whether the total weight increases.

[0148] Specifically, in response to an increase in the total weight, it indicates that the user is continuing to add ingredients to the cooking mechanism. Therefore, the first displacement signal is repeatedly acquired, and the determination of whether the total weight has increased is repeated. This approach can improve the accuracy of determining whether the total weight has increased, thereby improving the accuracy of the acquired ingredient weight, improving the accuracy of subsequent cooking control, and thus improving the cooking effect.

[0149] In other embodiments, similar improvements may be made to the control method of the cooking device, which will not be described in detail here.

[0152] 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.

[0153] 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.

[0154] In other embodiments, the cooking device also includes a temperature detection element, which is arranged in the inner pot, lid or heating mechanism of the cooking mechanism, and is used to directly obtain the temperature value of the inner pot, lid or heating mechanism as the temperature value of the cooking mechanism; the control mechanism is connected to the temperature detection element to control the operation of the temperature detection element.

[0155] Alternatively, the cooking device may be a pressure cooker, etc. The displacement detecting element may include a displacement sensor, such as a potentiometer displacement sensor, a capacitive displacement sensor, or a linear displacement sensor. The control mechanism may include a control chip, such as an MCU, etc., or a non-integrated circuit having control and data processing functions.

[0156] 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.

[0157] This application further proposes a computer storage medium, such as Figure 8 As shown, Figure 8 1 is a schematic diagram of a computer storage medium according to an embodiment of the present invention. The computer storage medium 80 stores program instructions 81, which are executed by a processor to implement the control method described above.

[0158] The program instructions 81 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.

[0159] The computer storage medium 80 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, etc.

[0160] 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.

[0162] Unlike the prior art, the present invention can obtain a first displacement signal before the cooking mechanism enters the cooking state and determine the weight of the food based on the first displacement signal, thereby achieving a more accurate weighing function. This facilitates controlling the operation of the cooking mechanism based on the weight of the food during subsequent cooking control, thereby improving the cooking control effect. Furthermore, obtaining a first displacement signal corresponding to the weight of the food and determining a preset relationship based on the first displacement signal can improve the accuracy of the correspondence between the displacement signal output by the displacement detection element and the pressure value within the cooking mechanism, or between the displacement signal output by the displacement detection element and the cooking parameter of the cooking mechanism, thereby improving the pressure control accuracy of subsequent cooking control and enhancing the cooking effect. Furthermore, controlling the operation of the cooking mechanism based on the weight, the preset relationship, and multiple reference angles of the second displacement signal can further improve the accuracy of cooking control, the pressure control accuracy of the cooking mechanism, and the cooking effect. Furthermore, this method can eliminate the need for pressure switch pressure control components or additional weight sensors, thereby reducing costs and increasing the ease of manufacturing and assembly. Therefore, the present invention can achieve a more accurate weighing function, improve the pressure control accuracy of the cooking device, enhance the cooking effect and user experience, and reduce costs.
