Description

Technical Field

[0001] This application relates to the field of cooking control technology, and more specifically, to a cooking control method, a pressure cooking appliance, and an electronic device. Background Technology

[0002] In pressure cooking appliances, temperature sensors are used to monitor the temperature during the cooking process in order to achieve precise temperature control and pressure regulation.

[0003] However, with the increase of usage time or the influence of external environment, the temperature sensor may malfunction. When the temperature sensors at the top and bottom fail, the internal pressure of the pressure cooker may not be effectively monitored and controlled, thus causing safety hazards.

[0004] There is currently no effective solution to the safety hazard posed by excessive pressure during cooking when the temperature sensor in a pressure cooking appliance fails. Summary of the Invention

[0005] The main objective of this application is to provide a cooking control method, a pressure cooking appliance, and an electronic device to solve the problem in the related art where excessive pressure can easily occur during cooking when the temperature sensor of the pressure cooking appliance fails, posing a safety hazard.

[0006] To achieve the above objectives, according to one aspect of this application, a cooking control method is provided. The method includes: activating the cooking function of a pressure cooker to perform a heating operation on the food inside the pressure cooker; controlling the pressure inside the pressure cooker to be lower than the pressure indicated by an overpressure condition; and determining whether the temperature detection function of the pressure cooker is effective based on the relationship between the parameter change of the temperature sensor of the pressure cooker and the corresponding parameter change threshold. By controlling the pressure inside the pot to be lower than the pressure indicated by the overpressure condition during heating, continuously monitoring the parameter change of the temperature sensor, and determining whether the temperature detection function is effective, the method achieves the effect of controlling the start and stop of the heating operation based on the effectiveness of the temperature detection function, effectively controlling the pressure inside the pot, and preventing safety hazards caused by excessive pressure inside the pot.

[0007] Optionally, controlling the internal pressure of the pressure cooker to be lower than the pressure indicated by the overpressure condition, and determining the effectiveness of the pressure cooker's temperature detection function based on the relationship between the parameter change of the temperature sensor and the corresponding parameter change threshold, includes: if the parameter change of the temperature sensor is detected to be greater than or equal to the corresponding parameter change threshold before the cumulative heating energy of the heating operation reaches the energy threshold, the temperature detection function is determined to be effective; if the parameter change of the temperature sensor is not detected to be greater than or equal to the corresponding parameter change threshold, heating continues until the cumulative heating energy of the heating operation is greater than or equal to the energy threshold, and then heating stops; before the heating stop time reaches the thermal equilibrium time, the effectiveness of the temperature detection function is determined based on the relationship between the parameter change of the temperature sensor and the corresponding parameter change threshold. By setting an energy threshold, the total energy input of the heating operation is limited, avoiding safety accidents caused by excessive pressure inside the pot during the process of determining whether the temperature detection function is effective. Introducing a thermal equilibrium time gives the temperature sensor sufficient response time, enabling accurate judgment even under conditions of slow heat conduction.

[0008] Optionally, before the heating stop time reaches the thermal equilibrium time, the effectiveness of the temperature detection function is determined based on the relationship between the parameter change of the temperature sensor and the corresponding parameter change threshold. This includes: if the detected parameter change of the temperature sensor is greater than or equal to the corresponding parameter change threshold, the temperature detection function is deemed effective; if the detected parameter change of the temperature sensor is not greater than or equal to the corresponding parameter change threshold, the temperature detection function is deemed ineffective. The introduction of the thermal equilibrium waiting phase avoids misjudgments caused by the initial heat conduction process or temperature sensor response delay, enabling a more accurate assessment of the temperature sensor's response capability. This improves the accuracy of determining the effectiveness of the temperature detection function and ensures the safety of the cooking process in pressure cooking appliances.

[0009] Optionally, the energy threshold is determined as follows: During the testing phase of the pressure cooker, the temperature sensor is controlled to be in a malfunctioning state, and a preset volume of food inside the pressure cooker is heated until the pressure inside the pressure cooker reaches its maximum pressure; the cumulative heating energy when the pressure inside the pressure cooker reaches its maximum pressure is determined as the energy threshold. The energy threshold is determined by simulating the temperature sensor malfunction during the testing phase of the pressure cooker and heating until the maximum safe pressure is reached. During the use phase of the pressure cooker, in the process of determining whether the temperature detection function is effective, energy less than this energy threshold is injected into the pressure cooker to prevent the pressure cooker from generating excessively high internal pressure due to overheating, thus avoiding safety hazards.

[0010] Optionally, the preset volume is determined by the cross-sectional area of ​​the inner pot of the pressure cooker and the lower limit of the water level. Determining the preset volume based on the cross-sectional area of ​​the inner pot of the pressure cooker and the lower limit of the water level ensures that there is sufficient water in the pot to absorb heating energy during temperature sensor effectiveness testing, preventing pressure overshoot.

[0011] Optionally, when the pressure cooker is equipped with multiple temperature sensors, determining the effectiveness of the pressure cooker's temperature detection function based on the relationship between the parameter changes of the temperature sensors and their corresponding threshold values ​​includes: if the relationship between the parameter changes of multiple temperature sensors and their corresponding threshold values ​​indicates that all temperature sensors are working normally, the temperature detection function is determined to be effective; if the relationship between the parameter changes of multiple temperature sensors and their corresponding threshold values ​​indicates that at least one temperature sensor is malfunctioning, the temperature detection function is determined to be ineffective. In the case of a pressure cooker equipped with multiple temperature sensors, determining the effectiveness of the pressure cooker's temperature detection function by combining the parameter changes of multiple temperature sensors with their corresponding threshold values ​​improves the accuracy of the determination.

[0012] Optionally, after determining whether the temperature detection function of the pressure cooker is effective based on the relationship between the parameter change of the temperature sensor and the corresponding parameter change threshold, the method further includes: if the temperature detection function is effective, continuing to execute the preset cooking program of the cooking function until the preset cooking program is completed. By first confirming the effectiveness of the temperature detection function and then safely continuing to execute the preset cooking program, not only is cooking safety enhanced, but the automated execution of the preset cooking program also reduces the complexity and uncertainty of user operation, ensuring cooking efficiency and quality.

[0013] Optionally, after determining whether the temperature detection function of the pressure cooker is effective based on the relationship between the parameter change of the temperature sensor and the corresponding parameter change threshold, the method further includes: if the temperature detection function is invalid, stopping the execution of the preset cooking program of the cooking function, or executing the pressureless cooking program of the cooking function. Stopping the preset cooking program or automatically switching to pressureless cooking mode when the temperature detection function is detected as invalid improves the cooking safety of the pressure cooker and avoids the cooking task being completed due to pressure cooker malfunction by providing a pressureless cooking program.

[0014] Optionally, the parameter change threshold for the temperature sensor refers to the minimum parameter change of the temperature sensor in an effective state when the temperature of the environment inside the pot where the temperature sensor is located changes. Determining the parameter change threshold based on the minimum parameter change of the temperature sensor in an effective state when the temperature of the environment where the temperature sensor is located lays the foundation for effectively evaluating the response capability and effectiveness of the temperature sensor in heating operations.

[0015] Optionally, the parameter changes of the temperature sensor include at least one of the following: the change in voltage of the temperature sensor, and the change in resistance of the temperature sensor. By monitoring the voltage or resistance changes of the temperature sensor and comparing them with the corresponding parameter change thresholds, the effectiveness detection of different types of temperature sensors for different pressure cooking appliances can be adapted, laying the foundation for flexible and accurate effectiveness detection of temperature detection functions.

[0016] According to another aspect of this application, a pressure cooking appliance is provided. It includes: a pot body comprising an inner pot, an outer pot, and a lid; a temperature sensor disposed on the inner pot; a heating element disposed on the outside of the inner pot; and a controller for cooking food using any of the above cooking control methods.

[0017] According to another aspect of this application, an electronic device is also provided, comprising a processor and a memory; the memory stores computer-readable instructions, and the processor is used to execute the computer-readable instructions, wherein the computer-readable instructions execute a cooking control method when they are run.

[0034] Figure 2 This is a structural block diagram of a pressure cooking appliance according to an embodiment of this application. Figure 2 As shown, the pressure cooking appliance includes:

[0035] The pot body includes an inner pot 21, an outer pot 22, and a lid 23.

[0036] The inner pot 21 is located inside the outer pot 22, and the lid 23 is located on top of the inner pot 21. The lid 23 is used to seal the internal space of the inner pot 21 and is equipped with a pressure relief valve.

[0037] Temperature sensors, mounted on the inner pot 21, may include a top temperature sensor 24 and a bottom temperature sensor 25.

[0038] The top temperature sensor 24 can be installed on the inner wall of the lid 23 to detect the temperature of the upper space inside the pot and to control the pressure inside the pot. The bottom temperature sensor 25 can be installed at the bottom of the inner pot 21 to detect the temperature of the bottom of the inner pot 21, thereby limiting the temperature and preventing the bottom of the pot from overheating.

[0039] The heating element 26 is located outside the inner pot 21 and can be a coil or a heating plate.

[0040] The outer pot 22 has a heating base inside, and the heating element 26 can be installed inside the heating base to convert electrical energy into heat energy to heat the food inside the pot.

[0041] The controller is used to cook food using the cooking control method of this embodiment to solve the problem in the related art that when the temperature sensor of the pressure cooking appliance fails, the pressure may become too high during the cooking process, posing a safety hazard.

[0042] This application provides, as follows: Figure 3 The cooking control method shown. Figure 3 This is a flowchart of a cooking control method provided according to an embodiment of this application.

[0043] Step S301: Start the cooking function of the pressure cooker to heat the food inside the pressure cooker.

[0044] Pressure cooking appliances refer to electrical appliances that use a high-pressure environment (above atmospheric pressure) for cooking, such as electric pressure cookers, to speed up cooking and preserve the nutrients in food.

[0045] Starting the cooking function refers to the operation of starting the pressure cooker to cook. Users start the cooking function of the pressure cooker through the operation interface (such as buttons, touch screen, etc.). The cooking function includes, but is not limited to, stewing meat, cooking porridge, etc.

[0046] Heating operation refers to the process by which a pressure cooker injects heat into the food inside the pot through a heating element. For example, the heating element can be a heating plate or an IH (Induction Heating) system, which converts electrical energy into heat energy to heat the food inside the pot. The power and time of the heating operation are adjusted according to the cooking function.

[0047] Step S302: Control the pressure inside the pressure cooker to be lower than the pressure indicated by the overpressure condition, and determine whether the temperature detection function of the pressure cooker is effective based on the relationship between the parameter change of the temperature sensor of the pressure cooker and the corresponding parameter change threshold.

[0048] The pressure indicated by the overpressure condition is the upper limit of the specified safe pressure, for example, the pressure inside the pot cannot exceed 350 kPa when the temperature sensor fails. At the beginning of the cooking function, under the premise that the pressure inside the pressure cooker is kept below the upper limit of the safe pressure, the effectiveness of the temperature detection function is determined to prevent overpressure caused by heating when the temperature detection function fails, thus laying the foundation for safe cooking in the future.

[0049] The effectiveness of the temperature detection function is determined by the change in the parameters of the temperature sensor and the threshold value of the change in parameters. The change in parameters reflects the response capability of the temperature sensor to changes in the temperature inside the pot during the heating operation. The change in parameters can be the difference between the parameters sampled by the temperature sensor at the current time and the initial parameters recorded when the cooking function is started.

[0050] A temperature sensor may include a top NTC (Negative Temperature Coefficient) and a bottom NTC. The change in the parameters of the top NTC can refer to the change in voltage or resistance, indirectly reflecting the temperature change. The change in the parameters of the bottom NTC can also refer to the change in voltage or resistance, indirectly reflecting the temperature change.

[0051] Effective temperature detection in a pressure cooker means the temperature sensor is working properly and accurately reflects temperature changes inside the pot. The threshold value for the parameter change of the temperature sensor is the standard for determining whether the sensor is working properly. If the parameter change is greater than or equal to the threshold value, the temperature sensor can detect temperature changes and works normally during heating; therefore, the temperature detection function is effective. If the parameter change is less than the threshold value, the temperature sensor cannot detect temperature changes, and it has malfunctioned or is ineffective during heating; therefore, the temperature detection function is invalid, and further safety measures should be taken, such as stopping the cooking program to prevent further pressure buildup and potential safety hazards.

[0052] The cooking control method provided in this application embodiment heats the food inside a pressure cooker by activating its cooking function. It controls the pressure inside the pressure cooker to be lower than the pressure indicated by an overpressure condition. Based on the relationship between the parameter changes of the pressure cooker's temperature sensor and the corresponding parameter change threshold, it determines whether the temperature detection function of the pressure cooker is effective. This solves the problem in related technologies where excessive pressure during cooking can easily lead to safety hazards if the temperature sensor fails. By controlling the pressure inside the pot to be lower than the pressure indicated by an overpressure condition during heating, continuously monitoring the parameter changes of the temperature sensor, and determining the effectiveness of the temperature detection function, the method effectively controls the start and stop of the heating operation based on the effectiveness of the temperature detection function, thereby effectively controlling the pressure inside the pot and preventing safety hazards caused by excessive pressure.

[0053] To improve the accuracy of determining whether the temperature detection function is effective, optionally, in the cooking control method provided in this application embodiment, controlling the pressure inside the pressure cooking appliance to be less than the pressure indicated by the overpressure condition, and determining whether the temperature detection function of the pressure cooking appliance is effective based on the relationship between the parameter change of the temperature sensor of the pressure cooking appliance and the corresponding parameter change threshold, includes: before the cumulative heating energy of the heating operation reaches the energy threshold, if the parameter change of the temperature sensor is detected to be greater than or equal to the corresponding parameter change threshold, the temperature detection function is determined to be effective; if the parameter change of the temperature sensor is not detected to be greater than or equal to the corresponding parameter change threshold, heating continues until the cumulative heating energy of the heating operation is greater than or equal to the energy threshold, and heating is stopped; before the heating stop time reaches the thermal equilibrium time, the temperature detection function is determined to be effective based on the relationship between the parameter change of the temperature sensor and the corresponding parameter change threshold.

[0054] The cumulative heating energy refers to the total energy input into the pot by the heating element of the pressure cooker from the start of heating to the current moment. The energy threshold is an upper limit set under the premise of ensuring safety, used to prevent excessive pressure rise inside the pot while determining the effectiveness of the temperature sensor.

[0055] For example, during the heating operation, the controller of the pressure cooker continuously monitors the cumulative heating energy Ein of the heating element and determines whether the cumulative heating energy Ein has reached a preset energy threshold EA. The energy threshold EA can be the energy required to raise the minimum amount of water allowed in the pot to the overpressure critical point. Before the cumulative heating energy Ein reaches the energy threshold EA, the change in the parameter E of the temperature sensor is simultaneously detected, and it is determined whether the change in parameter E is greater than or equal to the parameter change threshold e. If the change in the parameter E of the temperature sensor is greater than the parameter change threshold e, it indicates that the temperature detection function of the pressure cooker is effective, and the cooking function can proceed normally.

[0056] It should be noted that the temperature detection function is determined to be effective before the cumulative heating energy Ein of the heating operation reaches the energy threshold EA, so that even when the temperature sensor is on and the water level in the pot is at its minimum, the pressure inside the pot will not exceed the dangerous level.

[0057] If the temperature sensor cannot be confirmed to be effective before the cumulative heating energy Ein reaches the energy threshold EA, heating continues until Ein equals or exceeds EA, at which point heating stops and enters the thermal equilibrium waiting phase. During the thermal equilibrium waiting phase, the change in the temperature sensor parameter E is continuously monitored, and it is determined whether the change in parameter E is greater than or equal to the parameter change threshold e to confirm the effectiveness of the temperature detection function, until the thermal equilibrium period ends. Since it takes time for heat to conduct from the bottom of the inner pot to the liquid, the thermal equilibrium period is set to take into account the natural distribution of heat within the pot and the temperature sensor's response time, ensuring that the temperature sensor has sufficient time to respond to temperature changes.

[0058] It should be noted that the thermal equilibrium waiting phase provides a second opportunity to determine the effectiveness of the temperature sensor. Even if the effectiveness of the temperature detection function cannot be determined during the heating process due to uneven heat distribution or temperature sensor response delay, the effectiveness of the temperature detection function can be accurately determined through temperature stabilization during the thermal equilibrium phase and continuous monitoring of the temperature sensor.

[0059] This implementation dynamically controls the heating energy during the heating phase and the thermal equilibrium waiting phase to determine the effectiveness of the temperature detection function. On one hand, by setting an energy threshold, the total energy input for heating is limited, preventing safety accidents caused by excessive pressure inside the pot during the temperature detection process. On the other hand, a thermal equilibrium time is introduced to give the temperature sensor sufficient response time, enabling accurate judgment even under slow heat conduction conditions. Furthermore, by accurately controlling the heating energy and thermal equilibrium time, the effectiveness of the temperature detection function in different models of pressure cooking appliances can be verified.

[0060] Optionally, in the cooking control method provided in this application embodiment, before the heating stop time reaches the thermal equilibrium time, determining whether the temperature detection function is effective based on the relationship between the parameter change of the temperature sensor and the corresponding parameter change threshold includes: if the parameter change of the temperature sensor is detected to be greater than or equal to the corresponding parameter change threshold, the temperature detection function is determined to be effective; if the parameter change of the temperature sensor is not detected to be greater than or equal to the corresponding parameter change threshold, the temperature detection function is determined to be ineffective.

[0061] It should be noted that the heat balance waiting time is set to take into account the impact of different pressure cooking appliance materials and heating methods (such as heating plate heating and IH electromagnetic heating) on ​​the heat transfer rate. This allows the temperature sensor sufficient time to respond to changes in the pot's temperature while avoiding excessive waiting that could extend the cooking time. For example, for an IH heating electric pressure cooker, the heat balance time can be set to 3 minutes, while for a heating plate heating electric pressure cooker, the heat balance time can be set to 5 to 10 minutes.

[0062] During the thermal equilibrium waiting phase, the parameter change E of the temperature sensor is continuously monitored. If, before the end of the thermal equilibrium waiting phase, the parameter change of the temperature sensor is detected to be greater than or equal to its corresponding parameter change threshold e, the temperature sensor's temperature detection function is confirmed to be effective. If, from the start of heating until the end of the thermal equilibrium waiting phase, the parameter change E of the temperature sensor is not detected to be greater than or equal to the corresponding parameter change threshold e, the temperature detection function is considered to be faulty.

[0063] This embodiment, by introducing a thermal equilibrium waiting stage, avoids misjudgments caused by the initial heat conduction process or temperature sensor response delay, and can more accurately judge the response capability of the temperature sensor, thereby improving the accuracy of determining whether the temperature detection function is effective and ensuring the safety of the cooking process of the pressure cooking appliance.

[0064] To set a reasonable energy threshold, optionally, in the cooking control method provided in this application embodiment, the energy threshold is determined in the following way: during the testing phase of the pressure cooking appliance, the temperature sensor is controlled to be in a failure state, and a preset volume of food inside the pressure cooking appliance is heated until the pressure inside the pressure cooking appliance reaches the maximum pressure; the cumulative heating energy when the pressure inside the pressure cooking appliance reaches the maximum pressure is determined as the energy threshold.

[0065] The testing phase, within the design and manufacturing process of pressure cooking equipment, is a stage for verifying performance and safety. Controlling the temperature sensor to a faulty state refers to simulating a temperature sensor malfunction during the testing phase by using software simulation or hardware methods to prevent the sensor from correctly reporting temperature information.

[0066] The preset volume of food is a test subject set up for the standardized testing process. The preset volume can be the minimum volume of water allowed to be heated in the pot. Maximum pressure refers to the highest pressure that the pressure cooker can reach internally in the event of temperature sensor failure, avoiding exceeding the destructive pressure (i.e., pressure exceeding the structural tolerance limit). Cumulative heating energy is the total energy input during the process of heating the food to reach maximum pressure.

[0067] For example, during the testing phase, the temperature sensor is first simulated to be in a failure state using software or hardware means, i.e., it does not provide effective temperature feedback to the controller. Then, the cooking function is activated to heat a preset volume of water inside the pressure cooker, in order to evaluate the pressure control capability of the pressure cooker during the heating process under the condition of temperature sensor failure. The pressure inside the pot is continuously monitored during the heating operation, and the heating process is recorded until the pressure reaches the preset maximum safe pressure point. The cumulative heating energy when heating to the maximum pressure is recorded, i.e., the total energy consumed from the start of heating until the pressure inside the pot reaches the set maximum pressure. Finally, the above-mentioned cumulative heating energy is used as an energy threshold to control the heating operation during actual cooking, in determining whether the temperature detection function is effective, to prevent the pressure inside the pot from exceeding the safe range.

[0068] In this embodiment, the energy threshold is determined by simulating a temperature sensor failure during the testing phase of the pressure cooker and heating it to the maximum safe pressure. During the use phase of the pressure cooker, when determining whether the temperature detection function is effective, energy less than the energy threshold is injected into the pressure cooker to prevent it from generating excessive internal pressure due to overheating, thus avoiding safety hazards.

[0069] To ensure that the pressure inside the pot does not exceed the safety limit during the process of determining whether the temperature detection function is effective, optionally, in the cooking control method provided in this application embodiment, the preset volume is determined by the cross-sectional area of ​​the inner pot of the pressure cooking appliance and the lower limit of the water level.

[0070] The cross-sectional area of ​​the inner pot of a pressure cooker refers to the surface area of ​​the part of the pressure cooker that directly contacts the heating source. For the same pressure cooker, the cross-sectional area is fixed and depends on the size and shape of the inner pot, and can be calculated based on the diameter and shape of the inner pot.

[0071] The lower limit of the water level is the minimum water level allowed during cooking (e.g., 25 mm), which allows for the control of heating energy to prevent pressure overshoot even with a small amount of water.

[0072] The preset volume is determined by taking into account both the cross-sectional area of ​​the inner pot and the lower limit of the water level. For example, the cross-sectional area of ​​the inner pot can be multiplied by the lower limit of the water level to obtain the preset volume. The preset volume is a safe lower limit of water volume, that is, the minimum amount of water required to test the effectiveness of the temperature sensor during heating operation.

[0073] In this embodiment, the preset volume is determined based on the cross-sectional area of ​​the inner pot of the pressure cooking appliance and the lower limit of the water level, so that there is enough water in the pot to absorb the heating energy when the temperature sensor effectiveness test is carried out, thus preventing pressure overshoot.

[0074] The temperature response capability of the temperature sensor determines the effectiveness of the temperature detection function of the pressure cooking appliance. Optionally, in the cooking control method provided in this application embodiment, when the pressure cooking appliance is equipped with multiple temperature sensors, determining whether the temperature detection function of the pressure cooking appliance is effective based on the relationship between the parameter changes of the temperature sensors and the corresponding parameter change thresholds includes: if it is determined that multiple temperature sensors are working normally based on the relationship between the parameter changes of multiple temperature sensors and the corresponding parameter change thresholds, the temperature detection function is determined to be effective; if it is determined that at least one temperature sensor is malfunctioning based on the relationship between the parameter changes of multiple temperature sensors and the corresponding parameter change thresholds, the temperature detection function is determined to be ineffective.

[0075] Multiple temperature sensors can be the top NTC and bottom NTC present simultaneously in a pressure cooker, as well as possible additional temperature sensors. These sensors detect temperature changes at different locations, providing more comprehensive temperature information. A failure in the temperature detection function of a pressure cooker means that at least one temperature sensor fails to display the expected parameter change after sufficient energy is injected into the water in the pot; this may be due to a damaged temperature sensor.

[0076] For example, the pressure cooking appliance is equipped with a top NTC and a bottom NTC. The parameter change threshold corresponding to the top NTC is denoted as e1, and the parameter change threshold corresponding to the bottom NTC is denoted as e2. The difference between the current temperature value measured by the top NTC during heating and the initial temperature value recorded when the cooking function is started is denoted as E1, and the difference between the current temperature value measured by the bottom NTC during heating and the initial temperature value recorded when the cooking function is started is denoted as E2.

[0077] When the pressure inside the pressure cooker is lower than the pressure indicated by the overpressure condition, the pressure cooker's controller continuously monitors the parameter changes E1 of the top NTC and E2 of the bottom temperature NTC to determine whether the corresponding parameter change thresholds e1 and e2 have been reached, thereby promptly detecting whether there is a fault in the top NTC and bottom temperature NTC.

[0078] If the parameter change E1 of the top NTC is greater than or equal to e1, and the parameter change E2 of the bottom NTC is greater than or equal to the parameter change threshold corresponding to e12, it indicates that both the top and bottom NTCs can respond normally to temperature changes, confirming that the temperature detection function of the pressure cooker is effective. If the parameter change E1 of the top NTC is less than e1, or the parameter change E2 of the bottom NTC is less than the parameter change threshold corresponding to e12, it indicates that either the top or bottom NTC cannot respond normally to temperature changes, confirming that the temperature detection function of the pressure cooker is faulty.

[0079] In this embodiment, when the pressure cooking appliance is equipped with multiple temperature sensors, the effectiveness of the pressure cooking appliance's temperature detection function is determined by combining the parameter changes of multiple temperature sensors with the corresponding parameter change thresholds, thereby improving the accuracy of the determination.

[0080] In order to improve the continuity and efficiency of the cooking process while ensuring cooking safety, the cooking control method provided in this application embodiment may optionally, after determining whether the temperature detection function of the pressure cooking appliance is effective based on the relationship between the parameter change of the temperature sensor of the pressure cooking appliance and the corresponding parameter change threshold, the method further includes: if the temperature detection function is effective, continuing to execute the preset cooking program of the cooking function until the preset cooking program is completed.

[0081] Among them, the effective temperature detection function of the pressure cooker means that the temperature sensor of the pressure cooker can display the expected parameter changes after sufficient energy is injected into the water in the pot.

[0082] Preset cooking programs are a series of pre-set operating steps for specific cooking functions (such as stewing meat or cooking porridge) in pressure cooking appliances, including parameters such as heating time, heating power, and pressure level for each operating step.

[0083] Once the temperature detection function is confirmed to be effective, continue cooking according to the preset cooking program until the entire cooking process is completed.

[0084] For example, the cooking function initiated by the user is the rice cooking function. The preset cooking program of the rice cooking function includes a water absorption stage, a heating stage, a pressure holding stage, a pressure releasing stage, a rice simmering stage, and a heat keeping stage. During the water absorption stage, it is determined whether the temperature detection function of the pressure cooker is effective. If it is effective, the program of the water absorption stage continues to be executed, and then the programs of the heating stage, pressure holding stage, pressure releasing stage, rice simmering stage, and heat keeping stage are executed in sequence until the cooking is completed.

[0085] This embodiment enhances cooking safety by first confirming the effectiveness of the temperature detection function before safely continuing to execute the preset cooking program. Furthermore, the automated execution of the preset cooking program reduces the complexity and uncertainty of user operations, ensuring both cooking efficiency and quality.

[0086] While ensuring cooking safety, alternative cooking solutions can also be provided to reduce the inconvenience caused by the failure of the temperature detection function to use the pressure cooking appliance. Optionally, in the cooking control method provided in the embodiments of this application, after determining whether the temperature detection function of the pressure cooking appliance is effective based on the relationship between the parameter change of the temperature sensor of the pressure cooking appliance and the corresponding parameter change threshold, the method further includes: if the temperature detection function is invalid, stopping the execution of the preset cooking program of the cooking function, or executing the pressureless cooking program of the cooking function.

[0087] The invalid temperature detection function of the pressure cooker means that the temperature sensor of the pressure cooker fails to display the expected parameter change after sufficient energy is injected into the water in the pot.

[0088] A preset cooking program is a series of pre-defined operating steps in a pressure cooker for a specific cooking function (such as stewing meat or cooking porridge). These steps include parameters such as heating time, heating power, and pressure level for each operation. For example, if the user starts a rice cooking function, the preset cooking program for the rice cooking function includes a water absorption stage, a heating stage, a pressure holding stage, a pressure releasing stage, a rice simmering stage, and a heat keeping stage.

[0089] The pressureless cooking program in the cooking function differs from the preset cooking program. During the execution of the pressureless cooking program, the pressure inside the pot is close to or equal to atmospheric pressure, avoiding potential safety hazards caused by the failure of pressure control inside the pot. For example, the cooking function is a rice cooking function, and the pressureless cooking program of the rice cooking function includes a water absorption stage, a heating stage, a pressureless rice simmering stage, and a keep-warm stage.

[0090] In one optional implementation, the cooking function initiated by the user is the rice cooking function. During the water absorption stage, the effectiveness of the temperature detection function of the pressure cooker is determined. If it is ineffective, the preset cooking program can be stopped, cooking can be ended, and prompt information (such as display screen and sound alarm) can be issued. This allows the user to understand the status of the pressure cooker in a timely manner and make corresponding operating decisions, so as to prevent the pressure inside the pot from continuing to rise and causing uncontrolled pressure inside the pot when the temperature detection function fails, thus ensuring user safety.

[0091] In another optional implementation, if the cooking function has a pressureless cooking program option, and the temperature detection function fails, the user can switch from the preset cooking program to the pressureless cooking program, allowing the user to continue the cooking process while ensuring safety. For example, if the cooking function is a rice cooking function, and the temperature detection function fails, the water absorption stage continues to run, followed by the pressureless cooking program's heating stage, pressureless rice simmering stage, and keep-warm stage, until cooking is complete.

[0092] In this embodiment, when the temperature detection function is detected to be invalid, the preset cooking program is stopped or the system automatically switches to the pressureless cooking mode. This improves the cooking safety of the pressure cooking appliance and avoids the cooking task being completed due to the failure of the pressure cooking appliance by providing a pressureless cooking program.

[0093] In order to effectively evaluate whether the temperature sensor can correctly reflect the temperature change during the heating operation, optionally, in the cooking control method provided in the embodiments of this application, the parameter change threshold corresponding to the temperature sensor refers to the minimum parameter change of the temperature sensor in an effective state when the temperature of the pot environment where the temperature sensor is located changes.

[0094] The parameter change threshold refers to the minimum value that the temperature sensor must change in order to remain effective when the ambient temperature inside the pot where the temperature sensor is located changes. The parameter change can be the change in voltage or the change in resistance of the temperature sensor.

[0095] For example, during the testing phase, a pressure cooker is filled with water and injected with energy indicated by an energy threshold (i.e., the minimum heating energy required to avoid overheating when the water level is at its lowest). The water in the pressure cooker is heated, and the parameter change of the temperature sensor is recorded when the water level is full. This process continues until the minimum effective change sufficient to reflect temperature changes is reached, thus obtaining the parameter change threshold at which the temperature sensor is considered effective. This minimum parameter change is the minimum value after considering power supply fluctuations, measurement errors, and fluctuations in the NCT (Non-Constant Temperature) measurement itself. The threshold set based on this minimum parameter change has a certain tolerance.

[0096] It should be noted that by setting a threshold for parameter changes when the water volume is full, the system can still accurately determine whether the temperature sensor is responding to temperature changes even when the water volume is large, preventing misjudgments in large water environments. This allows for more accurate determination of whether the temperature sensor is responding to temperature changes even when the water volume is small, effectively covering the effectiveness detection needs of the temperature sensor in electric pressure cookers under different water volume conditions.

[0097] This embodiment determines the parameter change threshold based on the minimum parameter change of the temperature sensor in an effective state when the temperature of the environment where the temperature sensor is located, laying the foundation for effectively evaluating the response capability and effectiveness of the temperature sensor in heating operations.

[0098] The effectiveness of a temperature sensor can be determined by the change in voltage or resistance of the temperature sensor. Optionally, in the cooking control method provided in this application embodiment, the change in the parameters of the temperature sensor includes at least one of the following: the change in voltage of the temperature sensor and the change in resistance of the temperature sensor.

[0099] The voltage change of a temperature sensor refers to the change in voltage at the sensor terminals caused by temperature changes during the heating process. The temperature sensor reflects temperature changes through changes in its resistance, which in turn are converted into voltage changes, and are collected and processed by the controller's main chip.

[0100] For example, after the cooking function is started, the voltage change of each temperature sensor is collected and compared with a preset voltage change threshold. If the voltage change is greater than or equal to the voltage change threshold, it indicates that the temperature sensor can effectively respond to temperature changes; conversely, if the voltage change is less than the voltage change threshold, it indicates that the temperature sensor may be malfunctioning or responding abnormally, and further safety measures need to be taken.

[0101] The resistance change of a temperature sensor refers to the change in the sensor's resistance caused by temperature changes during the heating process. For example, the resistance of a negative temperature coefficient temperature sensor decreases as the temperature rises, and this change can be collected and processed by the controller's main control chip.

[0102] For example, after the cooking function is started, the resistance change of each temperature sensor is collected and compared with a preset resistance change threshold. If the resistance change is greater than or equal to the resistance change threshold, it indicates that the temperature sensor can effectively respond to temperature changes; conversely, if the resistance change is less than the resistance change threshold, it indicates that the temperature sensor may be malfunctioning or responding abnormally, and further safety measures need to be taken.

[0103] This embodiment monitors the voltage or resistance changes of the temperature sensor and compares them with the corresponding parameter change thresholds. This allows for the effective detection of different types of temperature sensors in different pressure cooking appliances, laying the foundation for flexible and accurate effective detection of temperature detection functions.

[0104] It also provides an optional cooking control method. Figure 4 This is a flowchart of an optional cooking control method according to an embodiment of this application, such as... Figure 4 As shown, the method includes:

[0105] Start the cooking function.

[0106] Read data, including reading the initial data a1 and a2 of the top NTC and bottom NTC, where a1 and a2 can be voltage data.

[0107] Cook according to the cooking program of the cooking function, and calculate the cumulative output energy Ein=P×t1, where P is the heating power of the pot and t1 is the cumulative heating time. That is, calculate the product of heating power and cumulative heating time to obtain the cumulative power.

[0108] Determine whether the cumulative output energy Ein is less than the energy threshold EA to prevent the pressure inside the pot from exceeding the safety limit when the temperature sensor malfunctions.

[0109] If Ein is less than EA, the sampling data b1 and b2 of the top NTC and bottom NTC are read in real time, and the changes E1 and E2 are calculated. E1 = |b1-a1|, E2 = |b2-a2|. If E1 and E2 are greater than e1 and e2 respectively, it is determined that the top NTC and bottom NTC are normal, the judgment program is exited, and cooking continues.

[0110] If Ein is greater than or equal to EA, or if E1 is not greater than e1 and / or E2 is not greater than e2, heating stops and heat transfer is waited for t2. During the waiting period, the sampling data b1 and b2 of the top NTC and bottom NTC are read in real time, and the changes E1 and E2 are calculated: E1 = |b1 - a1|, E2 = |b2 - a2|. If E1 and E2 are greater than e1 and e2 respectively, the top NTC and bottom NTC are judged to be normal, the judgment program is exited, and cooking continues. If E1 is not greater than e1 and / or E2 is not greater than e2, the function is exited and cooking ends.

[0111] In this embodiment, during the initial cooking stage of a pressure cooker, the changes in the parameters of the temperature sensor are monitored in real time and compared with the corresponding threshold values. This allows for accurate determination of the sensor's effectiveness. In the event of a temperature sensor malfunction, heating can be stopped promptly, effectively controlling the pressure inside the pot and preventing safety hazards caused by over-pressure. This ensures cooking safety while minimizing the impact on the normal cooking process.

[0112] It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases the steps shown or described may be executed in a different order than that shown here.
