Description

Technical Field

[0001] The present invention relates to the technical field of cooking equipment control, and in particular to a cooking equipment control method, a cooking equipment control device, a cooking equipment and a computer-readable storage medium. Background Art

[0002] As the pace of life accelerates, people have higher requirements for cooking speed. In order to further shorten the cooking time, most cooking methods use high-power heating to near boiling after the cooking starts. Therefore, in order to ensure the consistency of cooking speed and cooking effect, the timing of heating and ending boiling is crucial. If you exit too early, it is easy to cause problems such as slow cooking speed, insufficient boiling of food, uneven cooking of rice, undercooked rice on the surface, or thin porridge; if you exit too late, it is easy to cause overflow.

[0003] Since the temperature sensing package can reflect the temperature of the contents in real time, the current control method that exits when the temperature of the temperature sensing package reaches a certain point is often used during the heating stage. However, there is a certain delay in the temperature sensing package. The worse the sensitivity of the temperature sensing package, the faster the temperature of the contents changes, the more serious the temperature sensing delay, and the greater the difference between the temperature of the temperature sensing package and the actual temperature. When the initial temperature of the cooking equipment changes when it enters the cooking stage, the corresponding relationship between the temperature detected by the temperature sensing package and the actual temperature will also change, which will cause the actual temperature reached at the end of heating to be inconsistent with the expected temperature.

[0060] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0061] One of the core concepts of the embodiments of the present invention is that, since there is a certain delay in the temperature detection of the temperature sensing package, the corresponding relationship between the temperature detected by the temperature sensing package and the actual temperature will change when the cooking starts, which will cause the problem that the actual temperature reached at the end of heating is inconsistent with the expected temperature. Therefore, a control method for a cooking device is provided, which determines a first expected temperature by obtaining an initial temperature, heats according to a first heating power until the temperature detected by the temperature sensing package can reach the first expected temperature, and records the heating time from the initial temperature to the first expected temperature; adjusts the power to obtain a second heating power, heats according to the second heating power until the temperature detected by the temperature sensing package reaches the second expected temperature, and stops heating when the second expected temperature is reached.

[0062] Figure 1 1 is a flowchart of a method for controlling a cooking device provided by an embodiment of the present invention. The method may specifically include the following steps:

[0063] Step 101, obtaining an initial temperature detected by the temperature sensing package when the cooking device starts heating, and determining a first expected temperature according to the initial temperature;

[0064] Cooking equipment includes electric rice cookers, electric steamers, etc. The method described in the present invention can be applied to other product series that share the same principles as the quick rice cooking and quick porridge cooking functions on electric rice cookers, and the present invention is not limited to this.

[0065] Thermistor is an electronic component used to measure temperature, usually used in various cooking equipment to ensure the accuracy of temperature control. The working principle of the thermostat is based on the characteristic that its resistance value changes with temperature. The initial temperature is the temperature detected by the thermostat at the beginning of the first heating stage, and the first expected temperature is the temperature detected by the thermostat at the end of the first heating stage.

[0066] In this embodiment, the temperature sensing package is arranged in the cavity above the cooking container of the cooking device, and can be used to detect the air temperature of the upper cavity. When the cooking device starts heating, the temperature sensing package will detect the air temperature of the upper cavity of the cooking container before heating to obtain an initial temperature, and determine the expected temperature that the temperature sensing package needs to detect at the end of the first stage of heating based on the initial temperature. When the user uses the cooking device, the initial temperature detected will also be different as the ambient temperature changes. Therefore, it is necessary to adjust and determine the expected temperature based on the initial temperature detected at that time, so that the temperature change during the cooking process can be more consistent at different initial temperatures.

[0067] In some embodiments, step 101 may include the following sub-steps:

[0068] Sub-step S11, obtaining a reference initial temperature and a reference expected temperature; the reference initial temperature is the temperature detected by the temperature sensing package when a preset amount of food is added to the cooking device and heating begins; the reference expected temperature is the temperature detected by the temperature sensing package when a preset amount of food is added to the cooking device and the food is heated to a target temperature;

[0069] The reference initial temperature refers to the set temperature when the equipment or system starts working during the cooking process. The reference expected temperature refers to the specific temperature that the equipment or system needs to reach and maintain during the cooking process to ensure that the food can be cooked in the expected way. These temperatures are usually set according to specific cooking needs and food characteristics.

[0070] The preset amount of food refers to the weight or volume of the food to be cooked that is preset in advance according to specific settings during the cooking process. In this embodiment, it is usually set to the minimum preset amount of food for the cooking device.

[0071] In this embodiment, a minimum preset amount of food is added to the container of the cooking device and cooked and heated to achieve the expected cooking effect. At the same time, a temperature sensing probe is also provided in the cooking device for temperature measurement, and the actual temperature of the food can be detected to determine whether the expected temperature is reached. The cooking device heats the minimum preset amount of food added to the cooking device. At the beginning of cooking and heating, the temperature sensing package detects the air temperature of the upper cavity of the cooking device. The temperature detected at this time is the reference initial temperature. When the food is heated to the expected temperature, the temperature sensing package detects the air temperature of the upper cavity of the cooking device again, and the temperature detected at this time is used as the reference expected temperature.

[0072] Sub-step S12, determining a first expected temperature according to the reference initial temperature, the reference expected temperature, and the initial temperature.

[0073] After the cooking device obtains the reference initial temperature and the reference expected temperature, they are set in the cooking device, and this reference temperature data is used when the first expected temperature is subsequently determined.

[0074] In this embodiment, when the cooking device heats the food, the acquired initial temperature, the reference initial temperature, and the reference expected temperature are comprehensively considered to determine the first expected temperature. The first expected temperature needs to be adjusted for different initial temperatures. During the cooking process, a temperature sensing bag is used to monitor the temperature in real time to ensure that the temperature detected by the temperature sensing bag at the end of the first stage is within the set first expected temperature range.

[0075] In some embodiments, step S12 may include the following sub-steps:

[0076] Sub-step S121, determining the first expected temperature according to the reference expected temperature, the initial temperature, the reference initial temperature, the temperature sensing package sensitivity correction coefficient, the starting temperature correction coefficient and the heating power correction coefficient.

[0077] The sensitivity correction coefficient of the temperature sensing package refers to the coefficient used to adjust the sensitivity of the temperature sensing package in order to improve the measurement accuracy and reliability of the temperature sensing package in actual applications. Since the measurement accuracy of different temperature sensing packages is different, by introducing the sensitivity correction coefficient, the measurement results of the temperature sensing package can be corrected to improve the accuracy of heating.

[0078] The initial temperature correction coefficient refers to a coefficient used to correct the first expected temperature according to the initial temperature difference measured by the temperature sensing package in order to improve the adaptability of the ambient temperature during the cooking process.

[0079] The heating power correction coefficient refers to the different temperature sensing delays of the temperature sensing package due to different heating powers (i.e. heating rates) during the cooking process. The introduction of the heating power correction coefficient can further correct the temperature of the temperature sensing package at the end, thereby improving the accuracy of heating.

[0080] The sensitivity correction coefficient of the temperature sensing package, the starting temperature correction coefficient, and the heating power correction coefficient are determined by adding the minimum preset amount of food to the cooking device, heating the food to the expected temperature at different initial temperatures with a specific heating power (usually 80%-100% of the rated power of the cooking device), and obtaining the expected temperature of the temperature sensing package corresponding to different initial temperatures. Based on the obtained reference initial temperature and reference expected temperature as a benchmark, based on the fixed value reference initial temperature and reference expected temperature, different initial temperatures of the variables, and different initial temperatures of the dependent variable, the expected temperature of the temperature sensing package corresponding to the temperature, the sensitivity correction coefficient of the temperature sensing package, the starting temperature correction coefficient, and the heating power correction coefficient can be obtained through nonlinear function fitting.

[0081] In this embodiment, the first expected temperature can be obtained by comprehensively considering the acquired reference expected temperature, initial temperature, reference initial temperature, temperature sensing package sensitivity correction coefficient, starting temperature correction coefficient and heating power correction coefficient and performing comprehensive calculation.

[0082] In some embodiments, step S121 may include the following sub-steps:

[0083] The first expected temperature is calculated by the following formula:

[0084] T1=T ys1 -c1*a (T0-Tys2) +b1

[0085] Wherein, T1 is the first expected temperature, T ys1 is the reference expected temperature, T0 is the initial temperature, and T ys2 is the reference initial temperature, c1 is the sensitivity correction coefficient of the temperature sensing package, a is the starting temperature correction coefficient, and b1 is the heating power correction coefficient.

[0086] The sensitivity correction coefficient of the temperature sensing package, the starting temperature correction coefficient, and the heating power correction coefficient can be obtained through nonlinear fitting of the function. a is the starting temperature correction coefficient, ranging from 0.92 to 1.00; b1 is the heating power correction coefficient, ranging from 7 to 35; c1 is the sensitivity correction coefficient of the temperature sensing package, ranging from 5 to 11.

[0087] In this embodiment, based on the determined reference expected temperature, reference initial temperature, initial temperature, temperature sensing package sensitivity correction coefficient, starting temperature correction coefficient, and heating power correction coefficient, the first expected temperature can be comprehensively calculated according to the calculation formula of the first expected temperature.

[0088] Step 102, heating is performed according to a first heating power until the temperature detected by the temperature sensing package reaches the first expected temperature, and the heating time from the initial temperature to the first expected temperature is recorded;

[0089] The first heating power is generally 80%-100% of the rated power. Since changes in the heating power will cause changes in the corresponding relationship between the water temperature and the temperature of the temperature sensing package, the cooking device always heats with the first heating power for different first expected temperatures.

[0090] The heating time refers to the time that the cooking device needs to continue heating from the initial temperature to the first expected temperature during the cooking process.

[0091] In this embodiment, the cooking device heats according to the first heating power, and the temperature sensing package in the cooking device will detect the air temperature in the upper cavity of the device in real time. After determining the first expected temperature, the cooking device will heat, and the temperature sensing package will also detect the air temperature inside the device. Until the temperature detected by the temperature sensing package changes from the initial temperature to the first expected temperature, the first stage of heating will be stopped and the next stage will be entered. At the same time, the cooking device will also record the heating time of this stage to obtain a heating time data.

[0092] Step 103, adjusting the first heating power according to the heating duration to obtain a second heating power, and determining a second expected temperature according to the first expected temperature and the heating duration;

[0093] When the first heating stage ends and the second heating stage begins, the power needs to be adjusted to determine the power of the second stage for heating, and the second expected temperature also needs to be determined again.

[0094] The second expected temperature is the air temperature that the temperature sensor needs to detect when the cooking equipment enters the second heating stage. By further adjusting the expected temperature setting of the temperature sensor, it is ensured that the temperature change during the cooking process is more consistent under different food quantity conditions.

[0095] In this embodiment, the cooking device will record a heating time at the end of the first heating stage, and make corresponding adjustments based on the first heating power according to the heating time to obtain the second heating power. At the same time, the second expected temperature is determined based on the obtained heating time combined with the first expected temperature. Since the corresponding relationship between different amounts of food and the temperature change of the temperature sensing bag is different, it is necessary to make a second correction to the expected temperature according to the heating time, so that the temperature change during the cooking process is more consistent.

[0096] In some embodiments, step 103 may include the following sub-steps:

[0097] Sub-step S21, determining the current amount of food in the cooking device according to the heating time;

[0098] Since there is a delay when the temperature sensor detects the temperature, and the larger the amount of food, the slower the temperature rises, and the smaller the delay of the temperature sensor, at the same temperature detected by the temperature sensor, the larger the amount of food, the farther away from the target temperature at the end of the first heating stage.

[0099] If the amount of food is larger, more heat is required to reach the same temperature. Therefore, in order to speed up the cooking speed, the larger the amount of food, the more power the second heating stage needs to heat.

[0100] In this embodiment, the cooking device determines the current amount of food in the cooking device based on the heating time recorded in the first heating stage. The larger the current amount of food, the longer the corresponding heating time will be. Therefore, it is convenient and accurate to judge the current amount of food by the heating time.

[0101] Sub-step S22, determining a power adjustment value according to the current food amount;

[0102] In this embodiment, the cooking device determines the current amount of food according to the recorded heating time, and thus determines the power adjustment difference according to the current amount of food to adjust the power of the second heating stage. For example, if 1000W is used for heating in the first heating stage, then in the second heating stage, a smaller amount of food may be heated using 900W, and a larger amount of food may be heated using 1200W, etc. Generally, the heating power for a smaller amount of food is less than or equal to the first heating power, and the heating power for a larger amount of food is greater than or equal to the first heating power.

[0103] Sub-step S23, adjusting the first heating power according to the power adjustment value to obtain a second heating power.

[0104] In this embodiment, the cooking device needs to obtain the first heating power in the first heating stage, obtain the corresponding power adjustment difference based on the current amount of food determined by the heating time, the cooking device determines the amount of power that needs to be increased based on the power adjustment difference, and makes corresponding adjustments based on the first heating power to obtain the second heating power, and uses this power for heating in the second heating stage.

[0105] In some embodiments, step 103 may further include the following sub-steps:

[0106] Sub-step S31, determining the second expected temperature according to the first expected temperature, the heating time, the food amount correction coefficient, the temperature sensing bag sensitivity correction coefficient, and the heating power correction coefficient.

[0107] The temperature sensing package sensitivity correction coefficient is a parameter used to correct the sensitivity deviation of the temperature sensing package (usually a thermistor or thermocouple) when measuring temperature.

[0108] The heating power correction coefficient is used to correct the change in the corresponding relationship between the temperature sensing package and the water temperature caused by the heating power, thereby improving the accuracy of heating.

[0109] The food quantity correction coefficient is a coefficient used to correct the influence of different food quantities on the corresponding relationship between the temperature of the temperature sensing bag and the actual temperature of the food.

[0110] Since there is a delay in the temperature sensing package detecting the air temperature, the faster the temperature rises, the more serious the temperature sensing delay of the temperature sensing package, and the greater the difference between the temperature of the temperature sensing package and the actual temperature. For the above reasons, different first expected temperatures and food amounts (i.e. different heating times) are tested, and the preset second heating power is used for heating until the current food temperature reaches the expected temperature (such as 90°C) (the temperature detected by the temperature sensing probe arranged inside the cooking equipment) corresponding to the temperature of the temperature sensing package (i.e. the second expected temperature). Based on the variables of the first expected temperature and heating time, and the dependent variable of the second expected temperature, the food amount correction coefficient, the temperature sensing package sensitivity correction coefficient, and the heating power correction coefficient can be obtained through function surface fitting.

[0111] In this embodiment, the cooking device calculates the second expected temperature based on the first expected temperature and heating time obtained in the first heating stage, combined with the food amount correction coefficient, the temperature sensor sensitivity correction coefficient, and the heating power correction coefficient.

[0112] In some embodiments, the step S31 may further include the following sub-steps:

[0113] The second expected temperature is calculated by the following formula:

[0114] T2=T1-c2*d (△t1) +b2

[0115] Among them, T2 is the second expected temperature, T1 is the first expected temperature, c2 is the sensitivity correction coefficient of the temperature sensing bag, d is the food amount correction coefficient, △t1 is the heating time, and b2 is the heating power correction coefficient.

[0116] The food quantity correction coefficient, temperature sensing package sensitivity correction coefficient, and heating power correction coefficient can be determined through function surface fitting. d is the food quantity correction coefficient, ranging from 0.990 to 1.000; b2 is the heating power correction coefficient, ranging from 0 to 30; c2 is the temperature sensing package sensitivity correction coefficient, ranging from 50 to 5000.

[0117] In this embodiment, the cooking equipment calculates the second expected temperature according to the second expected temperature calculation formula, and substitutes the first expected temperature, heating time, food amount correction coefficient, temperature sensor sensitivity correction coefficient, and heating power correction coefficient into the formula for calculation. The second expected temperature can be confirmed based on the calculation results.

[0118] Step 104: heating according to the second heating power until the temperature detected by the temperature sensing package reaches the second expected temperature, and stopping heating when the second expected temperature is reached.

[0119] The second expected temperature is the upper chamber air temperature detected by the temperature sensor package at the end of the second heating stage of the cooking device. In the second heating stage, the expected temperature is corrected again according to the amount of food, and the temperature setting of the temperature sensor package is further adjusted to ensure that the temperature change during the cooking process is more consistent under different rice amounts.

[0120] In this embodiment, the cooking device will adjust the heating power to obtain a second heating power at the end of the first heating stage, and heat again according to the second heating power. At the same time, the temperature sensing bag will detect the air temperature in the upper cavity of the cooking device container in real time until the temperature detected by the temperature sensing bag changes from the first expected temperature to the second expected temperature. When the detected temperature reaches the second expected temperature, it indicates that the heating in this heating stage is completed.

[0121] Reference Figure 2 , shows a step logic diagram of a control method for a cooking device provided by an embodiment of the present invention, wherein the step logic includes the following:

[0122] like Figure 2 When the cooking device starts heating, it will detect the initial temperature of the temperature sensing bag (that is, the temperature detected by the temperature sensing bag before heating starts). After obtaining the initial temperature, it will calculate and determine the first expected temperature based on the initial temperature. After obtaining the first expected temperature, the cooking device will heat with a first heating power. When the temperature detected by the temperature sensing bag on the top of the device reaches the first expected temperature, the first heating stage ends and the timer inside the cooking device records the heating time of this heating stage. When the temperature detected by the temperature sensing bag on the top of the device does not reach the first expected temperature, it will continue to heat with the first heating power until the temperature detected by the temperature sensing bag reaches the first expected temperature.

[0123] When the cooking device obtains the heating time of the first heating stage, it will enter the second heating stage. The cooking device will determine the current amount of food based on the recorded heating time, thereby adjusting the power to obtain the heating power of the second heating stage, and determine the second expected temperature based on the first expected temperature and the heating time. The cooking device will heat according to the adjusted heating power until the temperature detected by the temperature sensing bag reaches the second expected temperature, and then stop the second heating stage.

Therefore, it is necessary to adjust and determine the expected temperature based on the initial temperature detected at that time, so that the temperature change during the cooking process can be more consistent at different initial temperatures.

[0128] A first heating module 302 is used to heat according to a first heating power until the temperature detected by the temperature sensing package reaches the first expected temperature, and record the heating time from the initial temperature to the first expected temperature;

[0129] In this embodiment, the cooking device heats according to the first heating power, and the temperature sensing package in the cooking device will detect the air temperature in the upper cavity of the device in real time. After determining the first expected temperature, the cooking device will heat, and the temperature sensing package will also detect the air temperature inside the device. Until the temperature detected by the temperature sensing package changes from the initial temperature to the first expected temperature, the first stage of heating will be stopped and the next stage will be entered. At the same time, the cooking device will also record the heating time of this stage to obtain a heating time data.

[0130] A second expected temperature determination module 303, configured to adjust the first heating power according to the heating duration to obtain a second heating power, and to determine a second expected temperature according to the first expected temperature and the heating duration;

[0131] In this embodiment, the cooking device will record a heating time at the end of the first heating stage, and make corresponding adjustments based on the first heating power according to the heating time to obtain the second heating power. At the same time, the second expected temperature is determined based on the obtained heating time combined with the first expected temperature. Since the corresponding relationship between different amounts of food and the temperature change of the temperature sensing bag is different, it is necessary to make a second correction to the expected temperature according to the heating time, so that the temperature change during the cooking process is more consistent.

[0132] The second heating module 304 is used to heat according to the second heating power until the temperature detected by the temperature sensing package reaches the second expected temperature, and stop heating when the second expected temperature is reached.

[0133] In this embodiment, the cooking device will adjust the heating power to obtain a second heating power at the end of the first heating stage, and heat again according to the second heating power. At the same time, the temperature sensing bag will detect the air temperature in the upper cavity of the cooking device container in real time until the temperature detected by the temperature sensing bag changes from the first expected temperature to the second expected temperature. When the detected temperature reaches the second expected temperature, it indicates that the heating in this heating stage is completed.

[0134] In one embodiment, the first expected temperature determination module 301 includes:

[0135] A reference temperature acquisition submodule is used to acquire a reference initial temperature and a reference expected temperature; the reference initial temperature is the temperature detected by the temperature sensing package when a preset amount of food is added to the cooking device and heating begins; the reference expected temperature is the temperature detected by the temperature sensing package when a preset amount of food is added to the cooking device and the food is heated to a target temperature;

[0136] In this embodiment, a minimum preset amount of food is added to the container of the cooking device and cooked and heated to achieve the expected cooking effect. At the same time, a temperature sensing probe is also provided in the cooking device for temperature measurement, and the actual temperature of the food can be detected to determine whether the expected temperature is reached. The cooking device heats the minimum preset amount of food added to the cooking device. At the beginning of cooking and heating, the temperature sensing package detects the air temperature of the upper cavity of the cooking device. The temperature detected at this time is the reference initial temperature. When the food is heated to the expected temperature, the temperature sensing package detects the air temperature of the upper cavity of the cooking device again, and the temperature detected at this time is used as the reference expected temperature.

[0137] The first temperature determination submodule is used to determine a first expected temperature according to the reference initial temperature, the reference expected temperature, and the initial temperature.

[0138] In this embodiment, when the cooking device heats the food, the acquired initial temperature, the reference initial temperature, and the reference expected temperature are comprehensively considered to determine the first expected temperature. The first expected temperature needs to be adjusted for different initial temperatures. During the cooking process, a temperature sensing bag is used to monitor the temperature in real time to ensure that the temperature detected by the temperature sensing bag at the end of the first stage is within the set first expected temperature range.

[0139] In one embodiment, the first temperature determination submodule includes:

[0140] The first expected temperature calculation subunit is used to calculate the first expected temperature according to the reference expected temperature, the sensitivity correction coefficient of the temperature sensing package, the starting temperature correction coefficient, the initial temperature, the reference initial temperature and the heating power correction coefficient.

[0141] In this embodiment, the first expected temperature can be obtained by comprehensively considering the acquired reference expected temperature, initial temperature, reference initial temperature, temperature sensing package sensitivity correction coefficient, starting temperature correction coefficient and heating power correction coefficient and performing comprehensive calculation.

[0142] In one embodiment, the first expected temperature calculation subunit is used to calculate the first expected temperature using the following formula:

[0143] T1=T ys1 -c1*a (T0-Tys2) +b1

[0144] Wherein, T1 is the first expected temperature, T ys1 is the reference expected temperature, T0 is the initial temperature, and T ys2 is the reference initial temperature, c1 is the sensitivity correction coefficient of the temperature sensing package, a is the starting temperature correction coefficient, and b1 is the heating power correction coefficient.

[0145] In this embodiment, based on the determined reference expected temperature, reference initial temperature, initial temperature, temperature sensing package sensitivity correction coefficient, starting temperature correction coefficient, and heating power correction coefficient, the first expected temperature can be comprehensively calculated according to the calculation formula of the first expected temperature.

[0146] In one embodiment, the second expected temperature determination module 303 includes:

[0147] A food quantity acquisition submodule, used to determine the current food quantity in the cooking device according to the heating time;

[0148] In this embodiment, the cooking device determines the current amount of food in the cooking device based on the heating time recorded in the first heating stage. The larger the current amount of food, the longer the corresponding heating time will be. Therefore, it is convenient and accurate to judge the current amount of food by the heating time.

[0149] A power adjustment value determination submodule, used for determining a power adjustment value according to the current food amount;

[0150] In this embodiment, the cooking device determines the current amount of food according to the recorded heating time, and thus determines the power adjustment difference according to the current amount of food to adjust the power of the second heating stage. For example, if 1000W is used for heating in the first heating stage, then in the second heating stage, a smaller amount of food may be heated using 900W, and a larger amount of food may be heated using 1200W, etc. Generally, the heating power for a smaller amount of food is less than or equal to the first heating power, and the heating power for a larger amount of food is greater than or equal to the first heating power.

[0151] The heating power determination submodule is used to adjust the first heating power according to the power adjustment value to obtain a second heating power.

[0152] In this embodiment, the cooking device needs to obtain the first heating power in the first heating stage, obtain the corresponding power adjustment difference based on the current amount of food determined by the heating time, the cooking device determines the amount of power that needs to be increased based on the power adjustment difference, and makes corresponding adjustments based on the first heating power to obtain the second heating power, and uses this power for heating in the second heating stage.

[0153] In one embodiment, the second expected temperature determination module 303 includes:

[0154] The second expected temperature calculation submodule is used to calculate the second expected temperature according to the first expected temperature, the food amount correction coefficient, the temperature sensing bag sensitivity correction coefficient, the heating time, and the heating power correction coefficient.

[0155] In this embodiment, the cooking device calculates the second expected temperature based on the first expected temperature and heating time obtained in the first heating stage, combined with the food amount correction coefficient, the temperature sensor sensitivity correction coefficient, and the heating power correction coefficient.

[0156] In one embodiment, the second expected temperature calculation submodule is used to calculate the second expected temperature using the following formula:

[0159] In this embodiment, the cooking equipment calculates the second expected temperature according to the second expected temperature calculation formula, and substitutes the first expected temperature, heating time, food amount correction coefficient, temperature sensor sensitivity correction coefficient, and heating power correction coefficient into the formula for calculation. The second expected temperature can be confirmed based on the calculation results.
