Detailed ways

In order to make the purpose, technical solutions, and advantages of this application clearer, the application will be further described in detail below in conjunction with the accompanying drawings. The described embodiments should not be regarded as limiting the application. Those of ordinary skill in the art have not made any suggestions. All other embodiments obtained under the premise of creative labor belong to the scope of protection of this application.

In the following description, the term "first\second\third" is only used to distinguish similar objects, and does not represent a specific order of objects. Understandably, "first\second\third" Where permitted, the specific order or sequence can be interchanged, so that the embodiments of the present application described herein can be implemented in a sequence other than those illustrated or described herein.

Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field of this application. The terminology used herein is only for the purpose of describing the embodiments of the application, and is not intended to limit the application.

The cooking method provided in the embodiment of the present application will be described below in conjunction with the equipment provided in the embodiment of the present application.

Referring to FIG. 1, FIG. 1 is a schematic diagram of an implementation flow of a cooking method provided by an embodiment of the application, which is applied to a cooking device, and the cooking device may be an electric rice cooker. The steps shown in FIG. 1 will be described below.

Step S101, in response to an operation instruction for starting the cooking device, control the cooking device to work at a first power until the internal temperature of the cooking device reaches a first temperature threshold.

Here, the operating instructions for starting the cooking device vary according to different control methods, where the control methods may include: voice, touch, keys, and other control methods. For example, when the cooking device is in a voice control mode, the operation instruction to start the cooking device may be a voice instruction issued by the user that can express the semantics of "start cooking"; when the cooking device is provided with a display screen, the operation instruction to start the cooking device It can be a touch operation (for example, click, press, slide, drag, etc.) instructions performed by the user on a certain position in the display screen. In some embodiments, the operation instruction for starting the cooking device may also be an operation instruction for the user to click or press a button set on the cooking device; the cooking device may also be remotely controlled by a terminal. In this case, the The operation instruction for starting the cooking device may be a control instruction sent by the user using the terminal.

When the user starts cooking, an operation instruction for starting the cooking device is sent to the cooking device, and the cooking device starts to work with the first power in response to the operation instruction. At this time, the temperature sensor provided inside the cooking device collects the internal temperature, and the cooking device operates at the first power until the internal temperature reaches the first temperature threshold and stops.

Here, the temperature sensor can be arranged on the upper cover, bottom, side or other positions of the cooking device to collect the temperature of the corresponding position inside the cooking device. When collecting the temperature of the upper cover inside the cooking device, the collected temperature can be the temperature of the upper cover of the cooking device during the cooking process; when collecting the bottom temperature inside the cooking device, the collected temperature can be the temperature of the heating plate of the cooking device , Or the bottom temperature of the carrier containing the cooking object in the cooking device; when collecting the side temperature inside the cooking device, the collected temperature may be the side temperature of the carrier containing the cooking object. In some embodiments, there may be multiple sensors arranged inside the cooking device, and multiple sensors are arranged at different positions on the upper cover and/or bottom and/or side of the cooking device. By collecting the temperature of different positions at the same time, according to the The temperature at different locations determines the temperature of the cooking object, which can improve the accuracy of the determined temperature of the cooking object.

In the embodiment of the present application, the temperature sensor may be provided on the upper cover of the cooking device. Since the temperature of the upper cover is mainly raised by the steam generated during the cooking process, the sensor provided on the upper cover is used to detect the temperature of the upper cover, which can be more accurate Determine the heating degree of the cooking object, so as to more accurately determine whether the cooking object is boiling, and prevent the cooking object from overflowing the cooking device.

Here, the first power may be the full power of the cooking device, that is, the maximum power, so as to heat the cooking object to the first temperature threshold as soon as possible. The first temperature threshold is a preset temperature value at which the cooking object in the cooking device has not yet boiled and will not overflow the cooking device. In some embodiments, the first temperature threshold may be 65 degrees Celsius (°C, degree Celsius).

Step S102, controlling the cooking device to work based on the second power until the change slope of the internal temperature of the cooking device satisfies a preset micro-boiling prediction condition.

When the internal temperature of the cooking device reaches the first temperature threshold, the temperature of the cooking object is already high. At this time, if the full power heating is continued to be used, the cooking object may overflow. Based on this, when the internal temperature reaches the first temperature threshold, that is, when the cooking object reaches the first temperature threshold, the cooking device is stopped to operate at the first power and starts to operate based on the second power. Here, the second power is less than or equal to the first power, and the average power of the cooking device operating based on the second power is less than the average power operating based on the first power.

In some embodiments, the second power is less than the full power, for example, the full power of the cooking device is 1000 watts (W, Watt), and the power of the cooking device is 700W when operating based on the second power. Or, in some embodiments, the second power is equal to the full power, but every time the cooking device operates at the second power for a period of time, it pauses for a period of time. For example, the full power of the cooking device is 1000W, and the cooking device operates at the second power of 1000W. 18 seconds (s, second), pause for 14s, continue to work at 1000W for 18s, pause for 14s, and cycle work accordingly.

When the change slope of the internal temperature of the cooking device satisfies the preset micro-boiling pre-judgment condition, the operation based on the second power is stopped. At this time, the cooking object in the cooking device has reached the micro-boiling, that is, the temperature of the cooking object is about to reach the boiling point.

In step S103, the cooking device is controlled to work based on the third power until the length of time during which the internal temperature of the cooking device remains unchanged reaches a first duration threshold.

When the change slope of the internal temperature of the cooking device meets the preset micro-boiling prediction condition, the temperature of the cooking object is about to reach the boiling point. At this time, if heating is continued based on the second power, the cooking object may overflow. Based on this, when the change slope of the internal temperature of the cooking device meets the preset micro-boiling prediction condition, the cooking device is controlled to stop working at the second power and start working based on the third power. Here, the third power is less than or equal to the second power, and the average power of the cooking device operating based on the third power is less than the average power operating based on the second power.

In some embodiments, the third power is less than the second power. For example, when the cooking device operates based on the third power, the power of the cooking device is 500W. Or, in some embodiments, the third power is equal to the full power, but every time the cooking device operates at the third power for a period of time, it pauses for a period of time. For example, the full power of the cooking device is 1000W, and the cooking device operates at the third power of 1000W. 10s, pause for 10s, continue to work at 1000W for 10s, pause for 10s, and cycle work accordingly.

Since the cooking objects in different altitude regions boil at different temperatures, that is, the boiling points are different, it is impossible to determine whether the temperature of the cooking objects has reached the boiling point using only the internal temperature. In practical applications, when the cooking object in the cooking device boils, the temperature will not rise any more, and the internal temperature remains unchanged when heating continues. The embodiment of the present application determines whether the cooking object reaches the boiling temperature based on this. When the time period during which the internal temperature remains unchanged reaches the first time length threshold, the cooking device is controlled to stop operating based on the third power. At this time, the temperature of the cooking object in the cooking device has reached the boiling point.

Step S104, controlling the cooking device to work based on the fourth power until the preset cooking time is reached.

When the time for which the internal temperature of the cooking device remains unchanged reaches the first time threshold, the temperature of the cooking object has reached the boiling point. At this time, if the heating is continued based on the third power, the cooking object may overflow. Based on this, when the length of time during which the internal temperature of the cooking device remains unchanged reaches the first time length threshold, the cooking device is controlled to stop working at the third power and start working based on the fourth power. Here, the fourth power is less than or equal to the third power, and the average power of the cooking device operating based on the fourth power is less than the average power operating based on the third power.

In some embodiments, the fourth power is less than the third power. For example, when the cooking device operates based on the fourth power, the power of the cooking device is 200W. Or, in some embodiments, the fourth power is equal to the full power, but every time the cooking device operates at the fourth power for a period of time, it pauses for a period of time. For example, the full power of the cooking device is 1000W, and the cooking device operates at the fourth power of 1000W. 5s, pause for 10s, continue to work at 1000W for 5s, pause for 10s, and cycle work accordingly.

In the embodiment of the present application, when the cooking object reaches the boiling point, the cooking device is controlled to continue to work based on the fourth power, and when the cooking time is reached, the cooking is automatically ended or the heat preservation is switched. Here, the cooking time is a preset value, for example, 45 minutes (min, minute).

On the basis of the embodiment shown in FIG. 1, the embodiment of the present application provides another cooking method. See FIG. 2. FIG. 2 is a schematic diagram of another implementation flow of the cooking method provided by the embodiment of the present application. The cooking method includes the following steps:

Step S201: In response to the operation instruction for starting the cooking device, control the cooking device to work at the first power until the internal temperature of the cooking device reaches a first temperature threshold.

In the embodiment of the present application, steps S201, S203, S205, and S206 correspond to steps S101 to S104 in the embodiment shown in FIG.

Step S202: Control the cooking device to stop working until the internal temperature of the cooking device drops to a second temperature threshold.

After the cooking device stops working based on the first power, there is still residual heat on the heating plate of the cooking device. In order to more accurately control the time point of preventing overflow and avoid the determined overflow time point due to the influence of the residual heat on the heating plate, the embodiment of the present application controls After the cooking device stops heating based on the first power, it pauses for a period of time. The heating plate conducts the residual heat on the heating plate to the carrier holding the cooking object through thermal conduction, so as to continue heating the cooking object, consuming the residual heat on the heating plate, and then Achieve more accurate and reliable anti-overflow control.

In some embodiments, the length of time for controlling the cooking device to stop working may be determined according to the internal temperature of the cooking device. In the embodiment of the present application, the sensor inside the cooking device can be set at the bottom of the cooking device. Since the bottom temperature is closest to the heating plate of the cooking device, the sensor located at the bottom can more accurately determine whether there is residual heat on the heating plate. The length of time to stop working.

The heating plate of the cooking device is provided with a sensor that collects the temperature of the heating plate. When the cooking device stops working based on the first power, the sensor collects the bottom temperature of the cooking device, that is, the temperature of the heating plate. The collected temperature is greater than the second temperature threshold and greater than the temperature of the cooking object, the heating plate conducts the residual heat on the heating plate through heat conduction, consuming the residual heat on the heating plate.

In the embodiment of the present application, the residual heat at the bottom of the cooking device is consumed through thermal conduction, so that the temperature of the cooking object increases and the temperature of the heating plate decreases, so that the temperature of the bottom of the cooking device collected by the sensor decreases. When the bottom temperature of the cooking device drops to the second temperature threshold, it is determined to control the cooking device to restart working.

In some embodiments, step S202 can also be replaced by: controlling the cooking device to stop working until the preset stop working time is reached. The length of time for controlling the cooking equipment to stop working can be determined according to the cooking volume of the cooking object. When the cooking volume of the cooking object is large, the cooking object is easy to overflow. At this time, you can stop working for a longer time (for example, 2min) to consume the heating plate. When the cooking volume of the cooking object is small, the cooking object is not easy to overflow. At this time, you can stop working for a short period of time (for example, 1 min) to consume the residual heat on the heating plate.

In some embodiments, step S202 can also be replaced by: controlling the cooking device to stop working until the internal temperature of the cooking device no longer changes within a set time period. The length of time for controlling the cooking device to stop working can be determined by the internal temperature of the cooking device. When the residual heat at the bottom of the cooking equipment conducts heat conduction, the temperature of the cooking object rises, causing the internal temperature of the cooking equipment to rise. When the temperature collected by the internal temperature sensor does not change within the set time, it indicates that the temperature of the cooking object is at The value of the temperature rise within the set time period is smaller or the temperature no longer rises, that is, the heat conduction speed is slow or no heat conduction is performed. At this time, the residual heat at the bottom of the cooking device is less, and the cooking device can be controlled to restart.

Step S203, controlling the cooking device to work based on the second power until the change slope of the internal temperature of the cooking device meets a preset micro-boiling prediction condition.

Here, the second power is less than or equal to the first power.

Step S204: Control the cooking device to stop working until the internal temperature of the cooking device drops to a second temperature threshold.

In the embodiment of the present application, the implementation process of step S204 is the same as the description in step S202 above. The implementation method and function are the same. They all consume residual heat on the heating plate, and continue to heat the cooking object through heat conduction, thereby achieving more accurate and reliable Anti-overflow control.

In step S205, the cooking device is controlled to work based on the third power until the length of time during which the internal temperature of the cooking device remains unchanged reaches a first duration threshold.

Here, the third power is less than or equal to the second power.

Step S206, controlling the cooking device to work based on the fourth power until the preset cooking time is reached.

Here, the fourth power is less than or equal to the third power.

The cooking method provided by the embodiment of the present application controls the cooking device to work at a first power in response to an operation instruction to start the cooking device, and when the internal temperature of the cooking device reaches the first temperature threshold, the cooking device is controlled to stop working, When the internal temperature of the cooking device drops to the second temperature threshold, the cooking device is controlled to operate based on the second power, and when the slope of the change in the internal temperature of the cooking device meets the preset micro-boiling pre-judgment condition, the cooking device is controlled again Stop working, when the internal temperature of the cooking device drops to the second temperature threshold again, the cooking device is controlled to work based on the third power, and when the length of time the internal temperature of the cooking device remains unchanged reaches the first duration threshold, the cooking device is controlled based on The fourth power works until the preset cooking time is reached, and the cooking device is controlled to stop working to consume the residual heat on the heating plate. The residual heat conducts heat conduction to realize the continuous heating of the cooking object, which can improve the accuracy of the overflow prevention control.

In some embodiments, step S102 in the embodiment shown in FIG. 1 or step S203 in the embodiment shown in FIG. 2 "controls the cooking device to operate based on the second power" can be implemented through the following steps S1021 to S1023, The following is a description of each step.

Step S1021: When it is detected that the internal temperature of the cooking device reaches a first temperature threshold, the cooking amount of the cooking object in the cooking device is acquired.

When it is detected that the internal temperature of the cooking device reaches the first temperature threshold, the temperature of the cooking object is already high. At this time, if full-power heating is continued, the cooking object may overflow. Based on this, when the internal temperature reaches the first temperature threshold, that is, when the cooking object reaches the first temperature threshold, the cooking amount of the cooking object in the cooking device is acquired. The adjustment ratio of the second power is determined according to the amount of cooking.

In the embodiments of the present application, the amount of cooking refers to the amount of cooking objects contained in the carrier that holds the cooking objects in the cooking device, including cooking ingredients and water. The cooking ingredients here can be grains such as rice, millet, corn or beans. The water can be tap water or mineral water. In some embodiments, the water can also be replaced with other liquids, such as milk, coconut milk, and the like.

Step S1022: Query a pre-stored cooking amount power relationship table according to the cooking amount, and determine that the adjustment ratio of the second power corresponding to the cooking amount is P:Q.

Here, both P and Q are positive numbers.

Regardless of whether the cooking equipment is affected by other external factors, the more cooking capacity, the greater the heating power required, and the less cooking capacity, the lower the heating power required. Therefore, the relationship table between the cooking capacity and the power should be established in advance. Stored in the storage area of the cooking equipment. After obtaining the current cooking amount, by querying the cooking amount power relationship table, it is determined that the adjustment ratio of the second power corresponding to the current cooking amount is P:Q. The adjustment ratio determined by different cooking quantities is different. When the cooking quantity is large, the ratio of the adjustment ratio of the second power is greater, which can speed up the cooking speed and improve the user's satisfaction with cooking using the cooking equipment.

Step S1023: Control the cooking device to work with a P:Q adjustment ratio based on the second power.

Wherein, operating the cooking device at the adjustment ratio of P:Q based on the second power includes the cooking device periodically operating at the second power for P seconds and stopping work for Q seconds.

According to the pre-stored cooking amount power relationship table, it is queried that the adjustment ratio of the second power matching the cooking amount obtained in step S1021 is P:Q, and the cooking device is controlled to adjust P:Q based on the second power. Working ratio work, that is, controlling the cooking device to work at the second power for P seconds, stop working for Q seconds, work at the second power for P seconds, and stop working for Q seconds, and then cycle until the slope of the change in the internal temperature of the cooking device satisfies Pre-judgment conditions for the preset micro-boiling.

In the cooking method provided by the embodiment of the present application, through the pre-stored cooking amount power relationship table, it is queried that the adjustment ratio of the second power corresponding to the current cooking amount is P:Q, so as to realize different cooking amounts based on different second powers. Of the cooking objects to work, so as to realize fast and fully automatic cooking, and improve the satisfaction of users using cooking equipment for cooking.

In some embodiments, the step S1023 "controlling the cooking device to work at the adjustment ratio of P:Q based on the second power" can be implemented through the following steps S0231 to S0234, which are described below in combination with each step.

Step S0231: When it is detected that the internal temperature of the cooking device reaches a third temperature threshold, the internal temperature of the cooking device is collected according to a collection period.

After controlling the cooking device to start working at the adjustment ratio of P:Q based on the second power, the internal temperature of the cooking device is monitored, and when it is detected that the internal temperature of the cooking device reaches the third temperature threshold, the cooking device’s information is collected according to the collection period. Internal temperature, and save the collected internal temperature in accordance with the acquisition sequence.

Step S0232: Determine the internal temperature collected at the current time as the first internal temperature, and determine the internal temperature collected at the historical time that is separated from the current time by a second time length threshold as the second internal temperature.

When the collection time length reaches the second time length threshold, the internal temperature collected at the current time is determined as the first internal temperature, and the internal temperature collected at the historical time interval of the second time length threshold at the current time is determined as the second internal temperature. For example, if the collection period is 1s and the second duration threshold is 25, the internal temperature collected at the current moment is the first internal temperature, and the internal temperature collected before 25s is the second internal temperature.

Step S0233: Determine a change slope of the internal temperature of the cooking device according to the first internal temperature, the second internal temperature, and the second duration threshold.

According to the first internal temperature c ₁ , the second internal temperature c ₂ and the second duration threshold t, the change slope k of the internal temperature of the cooking device is calculated, and the calculation formula is as shown in formula (1):

Step S0234: When the change slope meets a preset micro-boiling pre-judgment condition, control the cooking device to stop working based on the second power.

When the change slope is less than or equal to the preset slope threshold, it is determined that the change slope meets the preset micro-boiling prediction condition, and at this time, the cooking device is controlled to stop working based on the second power.

In the cooking method provided by the embodiment of the present application, the change slope of the internal temperature of the cooking device is determined by the two internal temperatures collected within the second duration threshold, and based on this, it is judged whether the temperature of the cooking object has reached a slight boiling point, so as to determine whether to stop based on The second power works to realize automatic cooking.

In some embodiments, before step S103 in the embodiment shown in FIG. 1 or step S205 in the embodiment shown in FIG. 2, the cooking method may further include: step S03, "control the cooking device to operate based on the fifth power until The internal temperature of the cooking device reaches a fourth temperature threshold, and the fifth power is less than or equal to the second power and greater than or equal to the third power".

When the change slope of the internal temperature of the cooking device meets the preset micro-boiling pre-judgment condition, it is possible that the current temperature of the cooking object (that is, the internal temperature of the cooking device) is still far from the boiling point, that is, the current temperature of the cooking object has not yet reached The fourth temperature threshold. At this time, in order to accelerate the cooking speed, the fifth power is used for heating, where the fifth power is less than or equal to the second power and greater than or equal to the third power. During the operation based on the fifth power, when it is detected that the internal temperature of the cooking device reaches the fourth temperature threshold, the cooking device is controlled to stop the operation based on the fifth power.

When the change slope of the internal temperature of the cooking device meets the preset micro-boiling pre-judgment condition, if the internal temperature of the cooking device has reached the fourth temperature threshold, there is no need to perform this step and go to step S103 or step S205.

In some embodiments, in step S103 of the embodiment shown in FIG. 1 or step S205 of the embodiment shown in FIG. 2, "controlling the cooking device to operate based on the third power" can be implemented through the following steps:

In step S1031, when it is detected that the internal temperature of the cooking device reaches the fourth temperature threshold, the boiling count is initialized to zero.

When controlling the cooking device to operate based on the third power, first determine the operating ratio based on the third power. When it is detected that the internal temperature of the cooking device reaches the fourth temperature threshold, the boiling count is initialized to 0, where the boiling count is a constant, which is used to count the number of times when the temperature rise during the heating process is continuously 0, every When the temperature rise value is not 0, the boiling count starts counting from 0 again.

Step S1032, controlling the cooking device to work with an M:N adjustment ratio based on the third power.

In the embodiment of the present application, after the boiling count is initialized, the cooking device starts to control the third power to work with an adjustment ratio of M:N. Here, M and N are both positive numbers, and M:N<P:Q, that is, cooking The average power when the device operates on the third power is less than the average power when the device operates on the second power. For example, at the beginning, the cooking device is controlled to work with a 3:5 adjustment ratio based on the third power, that is, heating with the third power for 3s, stopping the heating for 5s, then heating with the third power for 3s, stopping the heating for 5s, and so on.

In step S1033, when the working duration of the operation based on the third power with the M:N adjustment ratio is greater than or equal to the third duration threshold, the temperature rise value T of the internal temperature of the cooking device within the working duration is calculated.

Here, the third duration threshold may be a preset value, for example, 40s.

When the working duration of the work based on the third power and the M:N adjustment ratio is greater than or equal to the third duration threshold, the temperature rise value T of the internal temperature during the working duration is calculated by collecting the internal temperature of the cooking device. Record the internal temperature collected at the start of work based on the third power with the M:N adjustment ratio as T ₁ , and record the internal temperature collected after the working time as T ₂ , and the calculation formula for the temperature rise value T is obtained as: (2) Shown:

T=T ₁ -T ₂ (2);

Step S1034, if the temperature rise value T is 0, add 1 to the boiling count.

Judge the size of the temperature rise value T. If T=0, it indicates that the temperature of the cooking device has not changed during the current working time. At this time, the boiling count is increased by 1.

Step S1035: When the boiling count is less than the count threshold, the working time is set to 0, and the cooking device is controlled to continue to work with the M:N adjustment ratio based on the third power.

When the boiling count is less than the count threshold, it indicates that the time period during which the temperature has not changed has not yet reached the first duration threshold, and it is not enough to determine that the cooking object in the cooking device reaches the boiling point. At this time, the working time is reset to 0, and the cooking device is controlled to continue to work with the M:N adjustment ratio based on the third power.

In some embodiments, after the above step S1035, the method may further include the following steps:

Step S1036, if the temperature rise value T is greater than the fifth temperature threshold, the boiling count is 0, and N is less than the fourth duration threshold, update N+a to N, set the working duration to 0, and control the The cooking device continues to work with the M:N adjustment ratio based on the third power.

Here, a is a positive number. The fifth temperature threshold may be a constant, and the fifth temperature threshold meets the requirement of ensuring that the cooking object does not overflow when the temperature rises to the fifth temperature threshold during the working time. The fourth duration threshold is to avoid too low working power, such as heating for 3 seconds and stopping for 60 seconds, resulting in the cooking time being reached, the cooking object has not reached the boiling point. In the embodiment of the present application, a=T can be set, the fifth temperature threshold value is 1, and the fourth duration threshold value is 46.

When it is judged that the temperature rise value T is greater than the fifth temperature threshold, the boiling count is 0 and N is less than the fourth duration threshold, it indicates that the temperature of the cooking object rises too fast within a working duration, and there may be a risk of overflow, and the working power needs to be adjusted. The labor ratio is adjusted down. In the embodiment of the present application, N+a is updated to N, and the working time is set to 0, and the cooking device is controlled to continue to work with the adjustment ratio of M:N based on the third power. At this time, M:N is no longer the initial one. The value has been updated to the updated M:N. Since a is a positive number, the updated M:N is smaller than the pre-updated M:N, and the adjustment ratio of reducing the working power is realized, thereby avoiding the overflow of the cooking object.

In the embodiment of the present application, the value of M can be unchanged, for example, the heating is always for 3 seconds during heating, and the average heating power can be adjusted by adjusting the duration of stopping work N.

In step S1037, if the temperature rise value T is greater than the fifth temperature threshold and the boiling count is not 0, set the working time and the boiling count to 0, and control the cooking device to continue to use M : N's transfer is better than work.

If the temperature rise value T is greater than the fifth temperature threshold, but the boiling count is not 0, it indicates that the cooking device has passed at least 2 working hours so that the temperature rise value T is greater than the fifth temperature threshold. At this time, there is no need to adjust the working power ratio Make adjustments, set the working time and the boiling count to 0, and control the cooking equipment to continue to work based on the third power with an M:N adjustment ratio.

In step S1038, if the temperature rise value T is equal to the fifth temperature threshold and the boiling count is 0, the working time is set to 0, and the cooking device is controlled to continue the adjustment ratio of M:N based on the third power Work.

If the temperature rise value T is equal to the fifth temperature threshold and the boiling count is 0, it indicates that the temperature of the cooking device has just increased by the fifth temperature threshold within a working period of time. At this time, there is no need to adjust the working power adjustment ratio, and it will work Both the duration and the boiling count are set to 0, and the cooking device is controlled to continue to work with the M:N adjustment ratio based on the third power.

Step S1039, if the temperature rise value T is equal to the fifth temperature threshold, the boiling count is not 0 and N is greater than the fifth duration threshold, update Nb to N, and set the working duration and the boiling count to 0 , Controlling the cooking device to continue to work based on the third power with an adjustment ratio of M:N.

Here, b is a positive number. The fifth duration threshold is to avoid excessive working power, such as heating for 3 seconds and stopping for 10 seconds, causing the cooking object to overflow. Based on this, the fifth duration threshold is set to ensure that the cooking object will not overflow when the working power adjustment ratio is increased. In the embodiment of the present application, b=1 and the fifth duration threshold can be set to 13.

If the temperature rise value T is equal to the fifth temperature threshold, the boiling count is not 0 and N is greater than the fifth duration threshold, it indicates that the temperature of the cooking device has increased by the fifth temperature threshold within at least two working hours, indicating that the cooking object is within one working time The rising temperature is too slow, which prolongs the cooking time. At this time, the adjustment ratio of the working power needs to be adjusted larger. In the embodiment of the present application, N-b is updated to N, and the working time is set to 0, the boiling count is set to 0, and the cooking device is controlled to continue to work with the M:N adjustment ratio based on the third power. At this time, M:N is no longer the initial value, and has been updated to the updated M:N. Since b is a positive number, the updated M:N is greater than the pre-updated M:N, so that the adjustment ratio of the working power can be increased, and the cooking speed can be accelerated.

In some embodiments, after the above step S1039, the method may further include the following steps:

Step S10310: When the boiling count is not less than the count threshold, it is determined that the length of time for which the internal temperature of the cooking device remains unchanged reaches the first duration threshold, and the cooking device is controlled to stop operating based on the third power.

When the boiling count is not less than the counting threshold, it is determined that the length of time during which the internal temperature of the cooking device remains unchanged reaches the first duration threshold, indicating that the cooking object has reached the boiling point. At this time, the cooking device is controlled to stop operating based on the third power. In the embodiment of the present application, the first duration threshold may be an integer multiple of the second duration threshold, for example, 3 times, that is, the first duration threshold is 120s.

In some embodiments, in step S104 of the embodiment shown in FIG. 1 or step S206 of the embodiment shown in FIG. 2, "control the cooking device to operate based on the fourth power", because the boiling points of cooking objects in different altitude regions are different when they boil. , When the boiling point is the plain boiling point (that is, the boiling point is greater than or equal to 97°C), the cooking equipment is controlled to continue heating based on the fourth power at the adjustment ratio M: (N+5); when the boiling point is the plateau boiling point (that is, the boiling point is less than 97°C) At the time, the cooking device is controlled to continue heating based on the fourth power at the adjustment ratio M: (N+4). Here, M and N are respectively the M and N values determined based on the adjustment ratio M:N at the third power operation time when the time length during which the internal temperature of the cooking device remains unchanged reaches the first time length threshold, and the cooking device stops.

In the following, an exemplary application of the embodiment of the present application in an actual application scenario will be described.

The cooking device is exemplarily described in the embodiment of the present application. FIG. 3 is a schematic structural diagram of a cooking device provided by an embodiment of the application. As shown in FIG. 3, the cooking device according to an embodiment of the application includes an internal temperature detection system 31, an ambient temperature detection system 302, a heating system 304, and a control system 305 , Wherein the internal temperature detection system 31 may include an upper cover temperature detection system 301 and a bottom temperature detection system 303, and the control system 305 is connected to the upper cover temperature detection system 301, the ambient temperature detection system 302, and the bottom temperature detection system 301, respectively. The temperature detection system 303 is connected to the heating system 304. The upper cover temperature detection system 301 is configured to detect the upper cover temperature of the cooking device, the ambient temperature detection system 302 is configured to detect the temperature of the environment where the cooking device is located, and the bottom temperature detection system 303 is configured to detect the bottom temperature of the cooking device The heating system 304 is configured to heat the cooking object, and the control system 305 is configured to control the lid temperature detection system 301, the ambient temperature detection system 302, the bottom temperature detection system 303, and the heating System 304.

FIG. 4A is a schematic diagram of another implementation process of the cooking method provided by the embodiment of the present application. As shown in FIG. 4A, the cooking method of the embodiment of the present application includes the following steps:

Step S401, heating stage 1: heating with high thermal power (full power) until the internal temperature reaches the first temperature threshold.

Here, the internal temperature can be detected by an internal temperature detection system, such as an upper cover temperature detection system. The upper cover temperature detection system may be a temperature sensor, and the first temperature threshold may be set to 65°C according to the test data.

Step S402, stop the first stage: stop heating for the first preset time period.

The cooking amount of the cooking object is different, and the corresponding stopping time is different, and the first preset time period for stopping heating is set according to the cooking amount of the cooking object. By stopping the first stage, the waste heat of the heating plate is consumed, which provides a basis for the judgment of the next heating stage described in step S403. When the heating plate consumes residual heat to heat the cooking object, the heating method is heat conduction. If the residual heat of the heating plate is not consumed in advance, the heating will be stopped when the overflow temperature is reached. Since the heating plate still has residual heat, it will continue to heat the cooking object, which will cause the cooking object to overflow, so it needs to stop working in advance to release it. The waste heat of the heating plate can be used for more reliable anti-overflow control.

Step S403, heating in two stages: heating with different heating power for different cooking quantities, and pre-judge the slight boiling through the change of the internal temperature slope.

FIG. 4B is a schematic diagram of an implementation process of the heating process of the cooking method provided by the embodiment of the application, which is used to implement the heating process of step S403 of heating two stages. The heating two stages shown in FIG. 4B include the following steps:

In step S4031, the cooking device operates with a P:Q adjustment ratio based on the second power.

In the second stage of heating, the cooking equipment works with a P:Q adjustment ratio based on the second power, that is, heating with the second power for P seconds, stopping the heating for Q seconds, then heating with the second power for P seconds, and stopping heating for Q seconds, according to This loop.

In step S4032, it is determined whether the internal temperature reaches the third temperature threshold.

In the process of working based on the second power with the P:Q adjustment ratio, the internal temperature detection system detects the internal temperature. When it detects that the internal temperature reaches the third temperature threshold (such as 80°C), it indicates that the temperature of the cooking object has reached the first Three temperature thresholds. At this time, step S4033 is entered, and the micro boiling judgment is started. When it is detected that the internal temperature has not reached the third temperature threshold, return to step S4031 to continue working with a P:Q adjustment ratio based on the second power.

In step S4033, the internal temperature of the cooking device is collected according to the collection period and stored in a preset space.

Step S4034: Obtain the maximum value and the minimum value of the collected temperature in the preset space.

The internal temperature is collected and saved according to the set collection period, and the maximum and minimum values of the internal temperature collected in the preset space are obtained. Since the cooking settings are always working at this stage, the internal temperature cannot be lowered. Therefore, the collected The maximum value of the internal temperature is the internal temperature value collected at the current moment, and the minimum value of the internal temperature collected is the internal temperature value collected at the earliest time in the preset space.

In step S4035, the difference T between the maximum value and the minimum value is calculated.

In step S4036, it is judged whether T satisfies the slight boiling condition.

In step S4037, it is determined that the cooking device has slightly boiled.

Calculate the temperature rise value c of the cooking equipment during the period of collecting these two temperatures according to the maximum and minimum internal temperatures, and judge whether the micro-boiling condition is met according to c. If c does not meet the micro-boiling condition, continue to collect the internal temperature, Go to step S4033; if c satisfies the slight boiling condition, go to step S4037 to determine that the cooking equipment has been slightly boiling.

For example, set up 25 data recording spaces and record the collected internal temperature values once every second. After recording the 25 data recording spaces, calculate the last recorded internal temperature value and the first recorded internal temperature in the data recording space The value difference c, when c is less than the set temperature threshold (such as 5 ℃), or c and the recording time difference (that is, the difference between the time of the last recording in the data recording space and the time of the first recording) is greater than the preset When the slope is set, it indicates that the slight boiling condition has not been reached. At this time, delete the first recorded internal temperature value, leave a data recording space, continue to collect the current internal temperature value and record, and calculate the last in the data recording space again For the difference c between the internal temperature value recorded once and the internal temperature value recorded for the first time, the above steps are repeated until c satisfies the slight boiling condition, it is determined that the cooking device has reached the slight boiling, and step S404 is entered.

Step S404, stop 2 stages: stop heating for the second preset period of time.

When the internal temperature of the cooking device no longer rises within a certain period of time, step S405 is entered to continue heating. For example, 30 seconds after the internal temperature stops rising, it is set to enter the next heating stage described in step S405.

The purpose of step S404 is the same as that of step S402, that is, to consume the residual heat of the heating plate and provide a basis for the judgment of the next heating stage described in step S405. In the embodiment of the present application, the work is stopped in advance to release the waste heat of the heating plate, so as to perform a more reliable anti-overflow control.

Step S405, Boiling Phase 1: Identify the boiling point and fire control intensity of different altitude areas through a local proportional integral derivative (PID, Proportion Integral Differential) algorithm.

FIG. 4C is a schematic diagram of another implementation process of the heating process of the cooking method provided by the embodiment of the application, which is used to implement the heating process of step S405 of boiling stage 1. The boiling stage 1 shown in FIG. 4C includes the following steps:

In step S40501, the cooking device operates with an M:N adjustment ratio based on the third power.

In the boiling stage 1, the cooking equipment works with a M:N adjustment ratio based on the third power, that is, heating with the third power for M seconds, stopping heating for N seconds, then heating with the third power for M seconds, and stopping heating for N seconds. This loop.

Step S40502: Determine whether the internal temperature reaches the fourth temperature threshold.

During the operation process based on the third power and the M:N adjustment ratio, the internal temperature detection system detects the internal temperature. When it detects that the internal temperature reaches the fourth temperature threshold (such as 90°C), it indicates that the cooking object is about to boil. Proceed to step S40503. When it is detected that the internal temperature has not reached the fourth temperature threshold, it indicates that the cooking object is still relatively far from the boiling point, and the process returns to step S40501 to continue working with the M:N adjustment ratio based on the third power.

In step S40503, the boiling count is initialized to zero.

In step S40504, the heating duration is set to zero.

Step S40505, heating with the third power for M seconds, and stopping heating for N seconds.

In step S40506, it is determined whether the heating duration reaches the third duration threshold.

In the process of heating with the third power for M seconds and stopping heating for N seconds, the heating duration is counted. When the heating duration reaches the third duration threshold (for example, 40s), step S40507 is entered. When the heating duration does not reach the third duration threshold, continue heating with the third power for M seconds, stop heating for N seconds, and return to step S40505.

In step S40507, the temperature rise value T of the internal temperature during the heating time is calculated.

In step S40508, it is judged whether T is 0.

Calculate the temperature rise value T of the internal temperature during the heating time period. If the temperature rise value T is 0, that is, the internal temperature does not change during the heating time period, and step S40509 is entered. If the temperature rise value T is not 0, that is, the internal temperature changes during the heating time period. At this time, step S40512 is entered to determine the speed of the change to determine whether it is necessary to increase or decrease the heating stop time period N.

In step S40509, the boiling count is incremented by 1.

In step S40510, it is judged whether the boiling count is less than the count threshold.

When the boiling count is less than the counting threshold (for example, 3), it indicates that the time period for which the internal temperature remains unchanged has not reached the first time period threshold (for example, 120s). At this time, step S40504 is entered to start the heating process of the next heating time period. When it is judged that the boiling count is not less than the count threshold, step S40511 is entered.

In step S40511, it is determined that the length of time during which the internal temperature of the cooking device remains unchanged reaches the first time length threshold, and the cooking device is controlled to stop operating based on the third power.

After the execution of S40511 is completed, it is determined that the boiling two-stage heating can be performed, and step S406 is entered.

In step S40512, it is judged whether T is 1.

When the temperature rise value T is 1, it indicates that the internal temperature has risen by 1°C during the current heating time period, and step S40513 is entered. When the temperature rise value T is not 1, that is, when the temperature rise value is greater than 1, the process proceeds to step S40515.

In step S40513, it is judged whether the boiling count is 0.

If the temperature rise value T is 1 and the boiling count is 0, it indicates that the internal temperature has risen by 1°C within a heating time period, and there is no need to adjust the adjustment ratio of the third power, and step S40503 is entered to continue heating.

If the temperature rise value T is 1 and the boiling count is not 0, it indicates that the internal temperature has risen by 1°C within at least two heating periods, and the average heating power is small. In order to speed up the cooking speed, it is necessary to increase the third power Adjusting the working ratio, that is, shortening the duration of stopping heating without changing the duration of heating, and then proceeding to step S40514.

Step S40514, update N-b to N.

Here, b is a positive number, and N-b is updated to N, which shortens the duration of stopping heating and can effectively increase the cooking speed. Then go to step S40503 to continue heating.

In step S40515, it is judged whether the boiling count is 0.

If the internal temperature rise is greater than 1°C and the boiling count is 0, it indicates that the internal temperature rise value is greater than 1°C within a heating period, and the average heating power is larger. In order to avoid the cooking object from overflowing, it is necessary to reduce the third power adjustment. Working ratio, that is, without changing the heating duration, extend the heating stop duration, and proceed to step S40516.

If the internal temperature rise is greater than 1°C and the boiling count is not 0, it indicates that the internal temperature rise value is greater than 1°C in at least two heating periods, and there is no need to adjust the third power adjustment ratio, and step S40503 is entered to continue heating.

Step S40516, update N+a to N.

Here, a is a positive number, and N+a is updated to N, which extends the duration of stopping heating, which can effectively prevent the cooking object from overflowing. Then go to step S40503 to continue heating.

Step S406, boiling stage 2: perform micro-boiling control according to the boiling point and firepower control intensity.

After entering the second stage of boiling: when the boiling point is the plain boiling point (that is, the boiling point is greater than or equal to 97°C), the cooking equipment is controlled to continue heating based on the fourth power with the adjustment ratio M: (N+5); when the boiling point is the plateau boiling point (ie When the boiling point is less than 97° C.), the cooking device is controlled to continue heating based on the fourth power at the adjustment ratio M: (N+4) until the cooking is completed.

Here, M and N are respectively the M and N values determined based on the adjustment ratio M:N at the third power operation time when the time length during which the internal temperature of the cooking device remains unchanged reaches the first time length threshold and the cooking device stops. The condition for the end of the cooking may be that the cooking time is reached or an operation instruction to end the cooking is received.

In the cooking method provided by the embodiment of the present application, when the heating is started, the heating is performed with full power until the internal temperature detection system reaches the first temperature threshold, the heating is stopped for the first preset time, and the residual heat on the heating plate is consumed; Determine a smaller thermal power, and use a smaller thermal power to heat up. Pre-judge the micro-boiling through the internal temperature slope change. When it is determined that the micro-boiling is reached, stop heating for the second preset time and consume the residual heat on the heating plate again. ; Then through the local proportional integral derivative algorithm, identify the boiling point and fire control intensity of different altitude areas, and finally perform micro-boiling control according to the boiling point and fire control intensity, so as to prevent the cooking object from overflowing the cooking equipment while realizing fast and fully automatic cooking , It can improve the user's satisfaction with cooking with cooking equipment.
