Description

Control method and device of cooking equipment and storage medium

Technical Field

The invention relates to the field of household appliances, in particular to a control method and device of cooking equipment and a storage medium.

Background

Because the induction cooker is cheap, simple and convenient to use and high in power, many users like cooking porridge, cooking soup or steaming fish and the like by using the induction cooker. However, although cooking porridge, soup, or steaming fish in an electromagnetic oven is relatively fast, it takes several to several tens of minutes to cook porridge or soup (the time for boiling varies depending on the amount of soup) or steam fish. If the user is cooking soup or porridge, in the whole process of cooking porridge or soup, the user needs to often go to the front of the induction cooker to see whether the soup is boiled or overflowed, and if the soup is not boiled, the user continues to boil; if the soup in the electromagnetic oven is boiled, the power of the electromagnetic oven needs to be manually reduced to enable the electromagnetic oven to stew and transport the soup or porridge with lower power, so that overflow is avoided. If the user steams the fish or steams other foods, the user needs to go to the front of the induction cooker continuously to check whether the duration and degree of heating (power) of the induction cooker is proper or not, and if the duration and degree of heating are too large, the duration and degree of heating need to be adjusted to be low; if the temperature is proper, the cooking is continued.

This causes a lot of time waste and trouble (i.e. not being able to concentrate on other things) for the user.

In practice, the overflow detection device 204 is an electrode sensor, which includes: a first metal sheet 301 and a second metal sheet 302 in fig. 3A; here, when the first metal piece 301 and the second metal piece 302 of the electrode sensor are turned on, it is explained that the amount of bubbles is too large and the food may be in a spilled state.

The single chip microcomputer 203 is used for receiving the bubble amount generated by the food detected by the electrode sensor 204 and determining the current state of the food according to the bubble amount; and if the current state is an overflow state or a state about to overflow, controlling the overflow executing device to be in a preset working state, or controlling the overflow executing device to change working parameters.

Secondly, the overflow detecting device 204 is used for detecting the current state of the food, wherein detecting the current state of the food comprises: the temperature of the food in the pot is detected, and the temperature information is sent to the single chip microcomputer 203. The single chip microcomputer 203 is configured to obtain cooking information (the cooking information is the temperature of the food) of the food in the cooking device detected by the overflow detection device, and determine a current state of the food according to the cooking information; and if the current state is an overflow state or a state about to overflow, controlling the overflow executing device to be in a preset working state, or controlling the overflow executing device to change working parameters.

In practice, the overflow detection device 204 is a temperature sensor, as shown in fig. 3B, which is a negative temperature coefficient temperature sensor 304;

the negative temperature coefficient temperature sensor 304 is configured to detect a temperature change of food in the pan, and send a detected temperature value to the single chip microcomputer 203.

The single chip microcomputer 203 is used for receiving the temperature information of the food in the pot, which is sent by the negative temperature coefficient temperature sensor, and determining the current state of the food according to the temperature information. And if the current state is an overflow state or a state about to overflow, controlling the overflow executing device to be in a preset working state, or controlling the overflow executing device to change working parameters.

Thirdly, the overflow detecting device 204 is configured to detect a current state of the food, wherein detecting the current state of the food includes: the temperature of the food in the pot and the amount of bubbles generated by the food are detected, and the temperature information and the bubble information are sent to the single chip microcomputer 203. The single chip microcomputer 203 is configured to obtain cooking information of food in the cooking device (the cooking information is a temperature of the food and an amount of bubbles generated by the food) detected by the overflow detection device, and determine a current state of the food according to the cooking information; and if the current state is an overflow state or a state about to overflow, controlling the overflow executing device to be in a preset working state, or controlling the overflow executing device to change working parameters.

In practice, the overflow detection device 204 includes an electrode sensor and a negative temperature coefficient temperature sensor, wherein,

the first metal sheet 310 and the second metal sheet 311 constitute an electrode sensor for detecting the amount of bubbles generated from food in the pan.

And the negative temperature coefficient temperature sensor is used for detecting the temperature change of the food in the pot and sending the detected temperature value to the singlechip 312.

The single chip microcomputer 312 is configured to receive temperature information of food in the pot sent by the negative temperature coefficient temperature sensor and bubble amount information generated by the food sent by the electrode sensor, and determine a current state of the food according to the temperature information and the bubble amount information. And if the current state is an overflow state or a state about to overflow, controlling the overflow executing device to be in a preset working state, or controlling the overflow executing device to change working parameters.

When the overflow performing means is a lid pop-up means, the lid pop-up means is configured to adjust the lid 20 to an open state when the current state of the food in the lid is an overflow state or a state about to overflow. That is, when the overflow detecting means 204 detects that the food in the pot body is in an overflow state, the pot lid bouncing means automatically bounces the pot lid 20 to alleviate the overflow of the food.

The wireless transceiver module 202 is configured to receive a corresponding signal (for example, an overflow signal generated in an overflow state) sent by the single chip microcomputer 203 according to the current state of the food, and send the received overflow signal to the overflow executing device.

Means 205 for opening the vent valve, acting as an overflow actuator, the means 205 for opening the vent valve automatically opens when food overflows, to alleviate food overflow.

Here, when the food is in the overflow state, the overflow detection device 204 sends the detected food overflow state to the single chip microcomputer 203, the single chip microcomputer 203 generates a control instruction according to an overflow signal corresponding to the food overflow state, and sends the control instruction to the wireless transceiver module 202, and then the wireless transceiver module 202 sends the overflow signal to the overflow execution device (the device 205 for opening the exhaust valve) to open the exhaust valve 205; when food overflow is cancelled, the overflow detection device 204 detects that the overflow is cancelled, and the wireless transceiver module 202 sends an overflow cancellation signal to the overflow execution device (the device 205 for opening the exhaust valve) so that the overflow execution device (the device 205 for opening the exhaust valve) does not need to be opened any more.

In addition, when the overflow executing device is a power control device (such as an induction cooker), if the food is in an overflow state, the overflow detecting device 204 will detect the overflow state of the food, the single chip microcomputer 203 generates a control instruction according to an overflow signal corresponding to the overflow state of the food, and sends the control instruction to the wireless transceiver module 202, and then the wireless transceiver module 202 sends the control overflow instruction to the overflow executing device (such as an induction cooker) so as to reduce the heating power; when food overflow is cancelled, the overflow detection device 204 detects the overflow cancellation, and the wireless transceiver module 202 sends an overflow cancellation instruction to the overflow execution device (induction cooker) so that the overflow execution device does not continue to reduce power.

As shown in fig. 3A, when the overflow detection device includes an electrode sensor, the overflow detection device is located inside the electrode sensor cover 31 and includes an electrode sensor composed of a first metal sheet 310 and a second metal sheet 311, wherein the first metal sheet 310 is connected to the single chip microcomputer 312 through a wire 314, and the second metal sheet 311 is connected to the single chip microcomputer 312 through a wire 313. The single chip microcomputer 312 is the same as the single chip microcomputer 203 in fig. 2.

Fig. 3B is a schematic structural diagram of an inner side of a pot cover according to an embodiment of the present invention, and as shown in fig. 3B, the inner side of the pot cover 30 includes: a first metal sheet 301, a second metal sheet 302, an insulating rubber pad 303, and a Negative Temperature Coefficient (NTC) temperature sensor 304. The first metal sheet 301 and the second metal sheet 302 are separated by an insulating rubber pad 303, when the first metal sheet 301 and the second metal sheet 502 are connected (when overflow occurs or when the amount of bubbles is too large, the connection is made), an electrode sensor is formed, and the first metal sheet 301 and the second metal sheet 302 are installed inside the pot cover 30 and face the liquid level in the pot. The first metal sheet 301 is the same as the first metal sheet 310 in fig. 3A; the second metal sheet 302 is the same as the second metal sheet 311 in fig. 3A.

In the embodiment, the interaction process of the electrode sensor (as an overflow detection device), the single chip microcomputer and the wireless transceiver module is that the electrode sensor detects the overflow state of food in the process of cooking porridge or soup, when the food overflows, the electrode sensor is switched on, then the state corresponding to the overflow of the food is sent to the single chip microcomputer, the single chip microcomputer generates a corresponding signal according to the state corresponding to the overflow of the food, sends the corresponding signal to the wireless transceiver module, and sends the signal to the overflow execution device through the wireless transceiver module; and finally, the overflow executing device adjusts the power of the overflow executing device according to the received signal.

The NTC temperature sensor 304 is used for detecting the temperature change in the pan. When the electromagnetic oven is used for cooking porridge and soup, the electromagnetic oven is used for detecting the temperature change in the pot. Such as: in the period of time when congee or soup is just boiled, a temperature value is collected, and the temperature change speed in the period of time is seen, generally, in the case of liquid, the temperature change in the pot is relatively uniform and stable just when heating is started, and the temperature value collected from the electrode sensor in the period of time (namely, the first cooking period) can be used as a reference curve of the temperature change of signal processing in the later period (the second cooking period).

The NTC temperature sensor 304 may determine that the pot is dry-cooked if the temperature rises sharply in a short time during the process of cooking porridge or soup.

The NTC temperature sensor 304 can monitor the temperature in the pot in real time in the process of steaming fish or cooking porridge and soup, and is used for adjusting the power of the induction cooker, so that the temperature change of food (steaming fish, cooking porridge, soup and the like) in the pot can be controlled, and the purpose of accurately cooking delicious food can be finally achieved.

In this embodiment, the first metal sheet and the second metal sheet that constitute the electrode sensor are designed such that when water drops are stuck on the metal sheet, the water drops can quickly slide off, and therefore, a hydrophobic coating is applied to the surface of the metal sheet, for example: teflon (Teflon). The purpose of this is two:

firstly, when the bubbles overflowing outwards in the pot contact the electrode plates arranged in the pot cover, the electrodes are connected, the food overflow is identified, and after the food overflow is sent to the induction cooker, the heating power of the induction cooker is immediately reduced. When the heating power of the induction cooker is reduced, the bubbles in the pot can be quickly reduced, and when the bubbles are not reduced, the metal sheet can quickly slide the foams and water drops stuck on the metal sheet, so that the overflow can be quickly identified and cancelled, and when the induction cooker receives the cancelled overflow, other corresponding actions can be quickly made according to actual requirements.

Secondly, in the cooking process (steaming fish, cooking porridge or cooking soup and the like), the user is difficult to avoid taking the pot cover away, and the operations of adding food materials or adding water into the pot and the like are all interference signals, so that the user cannot identify food overflow. Therefore, it is necessary to recognize the state of the lid when the lid is removed and attached. When the pot is covered and heated on the pot, the water vapor in the pot can continuously and slowly increase along with the increase of time, and the water drops on the electrode plates on the pot cover can also continuously and slowly increase along with the increase of time; when the pot cover is removed from the pot, because the metal sheet on the pot cover is exposed in the air, water vapor attached to the metal sheet can be liquefied into small water drops, then the small water drops quickly drop from the metal sheet, and water drops on the electrode plate can continuously decrease along with the increase of time in the whole process of removing the pot cover from the pot (namely, the reduction speed of the quantity of bubbles generated by the food in the cooking information is greater than a second preset reduction speed). Therefore, based on this phenomenon, it is possible to recognize whether the lid is removed or not during the entire cooking process.

In order to improve the accuracy of the system for recognizing food overflow and removing the pot cover, a reference temperature value may be set, that is, when the temperature value detected by the NTC temperature sensor is less than the reference temperature value, the overflow detection device displays the detected food overflow as an interference signal, and the overflow execution device does not respond. For example, when the temperature is less than 70 degrees, the detected food overflow can be regarded as a disturbing signal, and the induction cooker (overflow executing means) does not respond to the power adjustment at this moment. If the temperature value detected by the NTC temperature sensor is higher than 95 ℃, when the food overflow is not detected, the food overflow detection is possibly problematic and normal, but when the cooking temperature is higher than 95 ℃, the food overflow is detected in a short time even if the food overflow does not occur, the state is determined as an overflow-imminent state, and then the heating power of the induction cooker (overflow execution device) can be actively reduced, so that the overflow is effectively prevented.

When the removed pot cover is just placed on an object with water, the temperature value on the NTC can be read. If the temperature is about 25 ℃ (or the temperature is suddenly reduced from a higher temperature to a lower temperature), the pan cover is still judged to be removed.

Fig. 4 is a schematic view of a composition structure of an overflow detecting device and a wireless transceiver module according to an embodiment of the present invention, and as shown in fig. 4, the overflow detecting device and the wireless transceiver module 40 are composed of a data collecting device 401, a single chip microcomputer 402, and a wireless transceiver module 403. Wherein, the data acquisition device 401 includes: NTC temperature sensors and electrode sensors.

Fig. 5 is a schematic view of a composition structure of an induction cooker according to an embodiment of the present invention, and as shown in fig. 5, the induction cooker 50 at least includes: a wireless transceiver module 501, a control drive unit 502, a heating coil 503 and a micro control unit 504.

The wireless transceiver module 501 is configured to receive a signal corresponding to a food overflow state or an overflow cancellation state sent by the wireless transceiver module of the pan body, and transmit the signal to the micro control unit 504.

The control driving unit 502 is composed of an Insulated Gate Bipolar Transistor (IGBT) and is configured to receive a control command from the micro control unit 504 to control the heating coil 503 of the induction cooker 50.

The micro control unit 504 is configured to receive a signal sent by the wireless transceiver module 501, and generate a control instruction according to the signal, so that the control driving unit 502 controls the heating power.

The heating coil 503 is configured to receive a control command for controlling the driving unit 502 to reduce the heating power.

During the cooking process, the overflow executing device works as follows:

the overflow detection device and the wireless transceiver module 40 perform data processing and analysis on the data (temperature value, bubble amount, and the like) acquired by the data acquisition sensor 401; then, the overflow state, the pot cover state and the temperature value in the cooking process are sent to the signal processing and control unit 50 of the induction cooker through the wireless transceiver module 403; the wireless transceiver module 501 of the induction cooker receives the overflow state, the lid state, and the temperature value during the cooking sent from the lid wireless transceiver module 403, and sends the overflow state, the lid state, and the temperature value during the cooking to the control micro-control unit 504 of the induction cooker, and the control unit 504 of the induction cooker controls the on-off state of the driving unit 502 according to the received overflow state lid state and the temperature value during the cooking, so as to achieve the purpose of controlling the heating power of the heating coil 503 of the induction cooker.

The single chip microcomputer 402 of the overflow detection device and wireless transceiving module 40 samples the overflow state, the lid state, and the temperature value during the cooking process at intervals to obtain the raw data of the overflow state, the lid state, and the temperature value during the cooking process, then performs a series of processing on the overflow state, the lid state, and the raw data of the temperature value during the cooking process to finally obtain a cooking curve of the overflow state, the lid state, and the temperature value variation during the cooking (steaming fish, boiling water, cooking soup, cooking porridge, etc.).

When the overflow signal, the pot cover state and the temperature value in the cooking process are detected, the single chip microcomputer for signal processing sends the current signal of the overflow state, the pot cover state and the temperature value in the cooking process to the matched induction cooker through the wireless transceiving module. When the electromagnetic oven receives the overflow state, the pot cover state and the temperature value in the cooking process from the pot cover through the wireless transceiver module, the micro control unit of the electromagnetic oven controls the on-off state of the driving unit 702 according to the received overflow state, the pot cover state and the temperature value in the cooking process, so that the purpose of controlling the heating power of the heating coil 503 of the electromagnetic oven is achieved, soup in the pot is kept on the cooking curve corresponding to the food material under the condition that the temperature of the food is not influenced, the purpose of controlling the cooking temperature of the food according to the cooking curve of the food strictly in the whole cooking process is achieved, and the purpose of accurately cooking the delicious food is achieved.

In the embodiment, the electrode sensor and the NTC temperature sensor have the characteristics of high precision, high sensitivity, simple circuit peripheral circuit and the like, so the cost is low and the reliability is high. Therefore, under the condition that the food cooked in the pot is not influenced, the food cooked in the pot is delicious, the overflow can be avoided, and the food is not burnt.

In the embodiment of the invention, the process of acquiring the food overflow state by the induction cooker comprises the following steps:

the first step, the process that water is heated to boiling in a vessel is a process that liquid state is gradually changed to gas state, water drops which are close to a heating source are continuously vaporized in the heating process of the water to form bubbles which rise in the water, the bubbles are broken when rising to the water surface to form water vapor, and the water vapor is emitted to the liquid surface.

In the second step, usually during boiling water, soup or porridge, a plurality of small water drops are vaporized to form small bubbles which rise and break. In the process that water is gradually boiled, water drops in the pot are gradually vaporized to form bubbles which rise and break to form water vapor, and the water vapor is diffused to the surface of the liquid and gathered in the pot.

And thirdly, in the process of boiling water, cooking soup or cooking porridge, the water vapor in the pot gradually changes from small to large and is gathered in the pot. During this process, the pressure inside the pan also changes.

Fourthly, generally, in the process of boiling water, making soup or cooking porridge, the water vapor in the pot is little at the beginning; as the temperature of the liquid in the pot is gradually increased, the water vapor in the pot is gradually increased, and when the water in the pot is completely boiled, the water vapor in the pot is the most.

Fifthly, as the food materials during cooking soup or the rice during cooking porridge contain some protein, some protein can be dissolved in water during cooking to play the role of a surfactant. In addition, some of the starch of rice and food materials also dissolves in water, increasing the viscosity of the water.

Sixthly, when the water in the pot is boiled and the steam flows out of the pot, just like blowing soap bubbles, bubbles which have higher surface tension and are difficult to break are blown out, along with the increase of the steam, the more the bubbles gather, the liquid level in the pot can also gradually rise, and when the bubbles rise to the edge of the pot, the bubbles overflow from the pot.

Seventh, the soup or porridge in the pan contains a large amount of protein and starch, so that their conductivity is high. When the bubbles overflowing to the outside contact the first metal piece 301 and the second metal piece 302 installed in the pot cover, the first metal piece 301 and the second metal piece 302 are connected to form an electrode sensor (the contact surface of the first metal piece 301 and the second metal piece 302 can be widened appropriately).

Eighthly, when the electrode sensor is turned on, the food in the pot is judged to be in an overflowing state, and then the single chip microcomputer 402 sends a signal corresponding to the overflowing of the food to the wireless transceiver module 501 of the induction cooker through the wireless transceiver module 403 (or as shown in fig. 2, the single chip microcomputer 203 sends the signal corresponding to the overflowing of the food to the wireless transceiver module 403 of the induction cooker through the wireless transceiver module 202).

An embodiment of the present invention provides a method for controlling a cooking apparatus, and fig. 6 is a flowchart illustrating a method for controlling a cooking apparatus according to an embodiment of the present invention, where as shown in fig. 6, the method includes the following steps:

step S601, acquiring a current state of food in the cooking apparatus.

Here, the cooking apparatus may be an electric rice cooker, a pan, a water kettle, an electric kettle, or the like. The current status may be that food is spilled, not spilled, or about to spill, etc.

Step S602, if the current state is an overflow state or a state about to overflow, controlling the overflow executing device to be in a preset working state or controlling the overflow executing device to change working parameters.

The overflow executing device can be a power control device, a device for opening an exhaust valve and the like;

correspondingly, if the overflow executing device further comprises a device for opening an exhaust valve, the preset working state is a state for adjusting the exhaust valve to be opened;

if the cooking equipment is provided with a pot cover, the overflow executing device also comprises a pot cover, and the preset working state is a state that the pot cover is opened;

if the overflow execution device is a power control device, the working parameter is power; and if the current state is the overflow state or the overflow imminent state, the power control device controls the power to be reduced or closed, namely the heating of the cooking equipment is stopped, so that the overflow of the food is inhibited.

In the control method of the cooking equipment provided by the embodiment of the invention, firstly, the current state of food in the cooking equipment is obtained; then, if the current state is an overflow state or a state about to overflow, controlling the overflow execution device to be in a preset working state or controlling the overflow execution device to change working parameters; wherein the overflow status is used for indicating the status that the food is overflowed, and the impending overflow status is used for indicating the status that the food is overflowed soon; so, when food takes place to overflow or is about to overflow, in time change operating condition, perhaps adjust the working parameter who overflows final controlling element to reach the mesh that the suppression food spills over, avoided the user to make a round trip to walk to look over whether food overflows moreover, promote user experience and feel.

In other embodiments, the step S601 of obtaining the current state of the food in the cooking apparatus may be implemented by:

step S611, obtaining cooking information of the food in the cooking apparatus.

Here, the cooking information includes at least: the temperature of the food, the amount of bubbles generated by the food. The bubble amount refers to bubbles generated from raw to cooked food in the cooking process, for example, in the process of cooking porridge or soup, the bubble amount is gradually increased in the process of boiling water, and the bubble amount is maximum when the food overflows again.

Step S612, determining the current state of the food according to the cooking information.

Here, the step S612 of determining the current state of the food (i.e., the over flow state) according to the cooking information includes:

and if the current temperature value of the food in the cooking information is greater than a preset temperature threshold value and the amount of bubbles generated by the food is less than a preset bubble threshold value, determining that the current state of the food is an overflow-imminent state.

Here, if the current temperature value of the food in the cooking information is greater than the preset temperature threshold value and the amount of bubbles generated by the food is less than the preset bubble threshold value, it may be understood that the food has reached ninety degrees more but overflow has not occurred (i.e. the amount of bubbles has not been greater than the bubble threshold value, for example, the generated bubbles have not reached the lid), the current status is determined as an about-to-overflow status.

The preset temperature threshold value can be set to 95 ℃ (DEG C); the bubble threshold can be set according to the needs of the user, for example, if the user wants to cook soup, the bubble threshold can be set to be relatively smaller, that is, when the water is just boiled, the power of the heating device is expected to be reduced, so as to cook soup with small fire; if the user is only boiling water, the bubble threshold can be set relatively large, since it is better to shut down the fire directly after the water is boiled.

And if the current temperature value of the food in the cooking information is greater than a preset temperature threshold value and the amount of bubbles generated by the food is greater than or equal to a preset bubble threshold value, determining that the current state of the food is an overflow state.

Here, if the current temperature value of the food in the cooking information is greater than the preset temperature threshold value and the amount of bubbles generated by the food is greater than or equal to the preset bubble threshold value, it may be understood that the temperature of the food has reached 100 ℃ (exceeding the preset temperature threshold value) and the amount of bubbles generated has reached the inner side of the lid, and it is determined that this state is an overflow state, and at this time, it is necessary to control the overflow executing device to be in a preset working state or to control the overflow executing device to change working parameters (i.e., open the lid, the exhaust valve or reduce power, etc.).

In other embodiments, the method further comprises:

if the current temperature value of the food in the cooking information is smaller than a preset temperature threshold value and the amount of bubbles generated by the food is smaller than a preset bubble threshold value, determining that the current state of the food is a non-overflow state;

maintaining or increasing the heating power of the cooking apparatus according to the non-overflow state.

Here, if the current temperature value of the food in the cooking information is less than the preset temperature threshold value and the amount of bubbles generated by the food is less than the preset bubble threshold value, it may be understood that the current power is continued to heat the food or the power is increased to heat the food when the food is not cooked by seventy percent.

An embodiment of the present invention provides a method for controlling a cooking apparatus, and fig. 7 is a schematic flowchart illustrating a method for controlling a cooking apparatus according to an embodiment of the present invention, where as shown in fig. 7, the method includes the following steps:

and step S701, recording the temperature of the food in a preset second cooking period.

Here, the recording of the temperature of the food in the preset second cooking period may be at least three scatter temperature values corresponding to the recorded temperature value of the food in the preset second cooking period, or may be a change curve of the temperature recorded in the preset second cooking period.

In step S702, a reference curve of temperature variation within a preset first cooking period is acquired.

Here, the first cooking period precedes the second cooking period in the course of cooking the food. That is, the first cooking period is a first half period of the food cooking process, and the temperature change is relatively smooth in the early stage of the food cooking, so the temperature change in the first cooking period is taken as a reference curve.

In step S703, if the temperature of the second cooking period does not match the reference curve of the temperature change, the current state of the food is acquired.

Here, the temperature of the second cooking period does not match the reference curve of the temperature variation, including two cases:

the first is that: if the temperature of the second cooking period is a scatter temperature value (for example, 5 temperature values), judging whether the scatter temperature values are all on a reference curve, and if all the scatter temperature values are on the reference curve, not acquiring the current state of the food; if the temperature values are not on the reference curve completely and the deviation between the temperature values not on the reference curve and the temperature values on the reference curve is larger than a preset threshold (for example, larger than 5 ℃), the current state of the food is obtained.

Secondly, the following steps: if the temperature in the second cooking period is a temperature curve, judging whether the trend of the temperature curve is the same as that of a reference curve and whether the temperature change in unit time is the same; if the trend of the temperature curve is the same as that of the reference curve and the temperature change in unit time is the same, not acquiring the current state of the food; and if the trend of the temperature curve is different from that of the reference curve and the temperature change in unit time is different, acquiring the current state of the food.

Here, the temperature curve is different from the reference curve in trend because the acceleration of the temperature change is different during the time of the temperature rise of the food during the cooking process, and therefore, if the temperature curve is different from the reference curve in trend, it is indicated that the temperature curve corresponds to two distinct cooking processes of the food with the reference curve; for example, the temperature of the food is increased before the food reaches the quintessence; after reaching maturity five times, the temperature rises in a decelerating manner, and obviously, the trend of the temperature change in the two stages is different.

Step S704, if the current state is an overflow state, generating a control command, where the overflow state is used to indicate that the food has been overflowed.

Here, the control instruction is for causing the overflow performing means to change the operating state or to change the operating parameter. The overflow executing device at least comprises one of the following devices: a power control device, a device for opening an exhaust valve; when the overflow executing device is a power control device, the operating parameter is power, for example, power reduction; when the overflow executing device is a device for opening the exhaust valve or a device for bouncing the pot cover, the preset working state is an opening state, for example, the pot cover is automatically opened or the exhaust valve is opened. If the power control device is not on the cooking apparatus, the power control device comprises an induction cooker or an electric heater.

When food is in an overflowing state, the overflowing detection device comprises an electrode sensor for detecting the amount of bubbles generated by the food, a single chip microcomputer for signal processing and the like, when the bubbles overflowing outwards from the food contact a metal sheet arranged in a pot cover, the electrode sensor is switched on, a signal corresponding to the overflowing of the food is identified, and the signal is sent to a device for heating the cooking device (namely, the overflowing execution device, such as an induction cooker or the cooking device), and then the overflowing execution device immediately reduces the heating power. When the heating power is reduced, the bubbles in the pot can be quickly reduced, after the bubbles are reduced, the metal sheet can quickly slide the foams and water drops stuck on the metal sheet, so that the overflow signal can be quickly identified to be cancelled, and after the heating equipment receives the cancellation of the overflow signal, other corresponding actions (such as turning off the heating equipment or continuing heating with low power) can be quickly carried out according to actual needs.

Wherein, the overflow executing device is a power control device, and when the operating parameter is power, the overflow executing device is controlled to change the operating parameter, including: controlling the power control device to reduce the heating power of the cooking equipment.

Step S705, sending the control instruction to the overflow executing apparatus.

In the control method of the cooking device provided by the embodiment of the invention, when the temperature change of the second cooking period is matched with the temperature change reference curve of the first cooking period, the current state of the food is acquired, so that when the temperature is higher, the state of the food is acquired to judge whether the food overflows or not, the overflow of the food can be accurately avoided, and the waste of system resources caused by frequent judgment can be avoided.

In other embodiments, the method further comprises the steps of:

step S71, acquiring the temperature of the cooking device.

Step S72, a falling speed of the temperature of the cooking device in a preset third cooking time period is greater than a first preset falling speed, or a falling speed of the amount of bubbles generated by the food in the cooking information is greater than a second preset falling speed; wherein the third cooking period is any one period of the whole cooking process.

Here, the speed of the temperature of the cooking device decreasing in the preset third cooking time period is greater than the first preset speed, or the speed of the food bubbles decreasing in the cooking information is greater than the second preset speed, it can be understood that the lid of the cooking device (i.e., the lid with the temperature sensor) is away from the body and placed on an object with a lower temperature, for example, when the lid is placed on an object with ice water, the temperature of the lid rapidly decreases, and when the lid is removed, the food bubbles decreasing significantly, and then it is determined that the relative position of the lid of the cooking device and the body of the cooking device changes (i.e., the lid is away from the body).

And step S73, determining that the relative position of the pot cover of the cooking device and the pot body of the cooking device changes, wherein the overflow executing device keeps the current working state and does not change the working parameters.

Here, after it is determined that the relative position of the cover of the cooking apparatus and the body of the cooking apparatus is changed, if the food has reached sixty-percent doneness, the power control means is caused to keep the current power to continue heating, and if the food is less than sixty-percent doneness, the heating power is increased to continue heating.
