Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative and intended to explain the present invention and should not be construed as limiting the present invention.
A food amount recognition method and apparatus, a cooking method and apparatus, a storage medium, and a cooking appliance according to embodiments of the present invention will be described below with reference to the accompanying drawings.
Fig. 1 is a flowchart of a method for identifying a food amount according to an embodiment of the present invention.
First, it should be noted that the method for identifying the amount of food according to the embodiment of the present invention can be applied to household common cooking appliances, such as an electric rice cooker, and can also be applied to a commercial electric rice cooker, which is not limited herein.
As shown in fig. 1, the method for recognizing the amount of food according to the embodiment of the present invention includes the following steps:
and S10, when the cooking appliance is in a temperature rising stage in cooking, acquiring the heating parameters of the cooking appliance in the stage and the temperature of the environment where the cooking appliance is currently located.
In this embodiment, a method of recognizing the amount of food will be described by taking rice as an example. First, in the process of cooking rice by the cooking appliance, the rice can be generally divided into five stages, namely a water absorption stage, a temperature rise stage, a boiling maintaining stage, a stewing stage and a heat preservation stage. Alternatively, the temperature sensor may be disposed on the cooking appliance for monitoring whether the cooking appliance enters the warming phase, and more specifically, a temperature threshold may be set, and then the temperature detected by the temperature sensor is compared with the temperature threshold to determine, and if the temperature detected by the temperature sensor is greater than the temperature threshold, it indicates that the cooking appliance starts entering the warming phase. Similarly, another temperature threshold may be set, and when the temperature detected by the temperature sensor is maintained at the temperature threshold, it indicates that the cooking appliance has ended the warming phase and entered the boiling maintaining phase. It will be appreciated that other sensors may be provided to operate in conjunction with the temperature sensor to monitor various stages of the cooking appliance.
When the cooking appliance is in the temperature rise stage, the heating parameters of the cooking appliance in the stage are obtained, specifically, the heating power and the heating time of the cooking appliance in the stage can be obtained, and the temperature of the current environment of the cooking appliance is also obtained. Specifically, in this embodiment, a power detection device may be configured to measure the heating power of the cooking appliance in the temperature-raising stage, and the heating time of the cooking appliance in the temperature-raising stage may be obtained according to the duration of the cooking appliance in the temperature-raising stage, and specifically, the timing module may participate in the calculation, when it is monitored that the cooking appliance enters the temperature-raising stage, the timing module is started to start timing, and then when the cooking appliance exits the temperature-raising stage and enters another stage, the timing module ends timing. The temperature of the environment in which the cooking appliance is located in the embodiment can be detected by arranging a thermometer on the outer insulating and heat-insulating shell of the cooking appliance, and the thermometer is used for displaying the temperature of the environment in which the cooking appliance is located currently. Therefore, the temperature of the environment where the cooking appliance is located, and the heating power and the heating time of the cooking appliance in the temperature rise stage can be accurately obtained through the method, it should be noted that the example is only used for explaining one method of the heating power, the heating time and the temperature of the environment where the cooking appliance is located in the temperature rise stage, and the data can also be obtained through other methods, which is not specifically limited by the present invention.
And S20, calculating the heating work amount of the cooking appliance at the temperature rising stage according to the heating parameters of the cooking appliance at the temperature rising stage and the temperature of the environment where the cooking appliance is currently located.
Specifically, after the heating power data, the heating time data and the temperature data of the current environment where the cooking appliance is located in the temperature rising stage of the cooking appliance are obtained through the calculation in the step S10, the heating work amount of the cooking appliance in the stage can be calculated according to the obtained data. It should be noted that, in this embodiment, the temperature of the environment where the cooking appliance is located is required to be obtained to calculate the heating work amount of the cooking appliance, so as to improve the calculation accuracy of the heating work, the cooking appliance is generally set to a standard room temperature when being shipped from a factory, the standard room temperature indicates the environment temperature where the cooking appliance is located, that is, the cooking appliance operates at the environment temperature, and other operating parameters of the cooking appliance may be set based on the standard room temperature. It is understood that the standard temperature corresponding to different cooking appliances may be different, and the standard temperature may be different for the cooking appliances sold in different places, and in some cooking appliances, a plurality of different standard temperatures may be set for the user to select. According to the embodiment, the difference between the temperature of the environment where the cooking appliance is located and the preset standard room temperature is calculated, the heating time of the cooking appliance is corrected according to the difference, and the heating workload of the cooking appliance is obtained according to the heating power and the corrected heating time.
In an embodiment of the present invention, the heating work amount of the cooking appliance in the warming-up stage can be calculated according to the following calculation formula: w ═ P (T + mT), where W represents the heating work of the cooking utensil in the temperature rise phase, P represents the heating power of the cooking utensil in the temperature rise phase, T + mT represents the heating time of the cooking utensil after correction, where T represents the heating time of the cooking utensil in the temperature rise phase without correction, m represents a preset coefficient, which is a "temperature difference-time" coefficient, T represents the temperature difference, and T ═ T t –T 0 ，T t Indicating the ambient temperature, T, of the cooking appliance in the current environment 0 Indicating a preset standard room temperature.
Specifically, in this embodiment, the ambient temperature T of the cooking appliance in the current environment is first measured t And a preset standard room temperature T 0 The difference is made to obtain a temperature difference value T, and then the temperature difference value T is multiplied by a preset "temperature difference-time" coefficient m to obtain a time, and it can be understood that the work obtained by multiplying the time by the power P is the work of the cooking utensil for supplementing the temperature difference between the working environment temperature and the standard temperature. For example, when T ═ T t –T 0 In the case of > 0, that is, when the current ambient temperature of the cooking appliance is greater than the standard temperature, since the heating time of the cooking appliance is reduced when the food is heated to the same temperature, it is necessary to add time mT for supplement so as to ensure the cooking effect of the food. After the heating time difference caused by the temperature difference is calculated, the time is added to the heating stage of the cooking utensilThe total heating time in (1) is corrected to obtain a total time sum (t + mT), and then the total time is multiplied by the heating power P of the cooking appliance in the temperature rising stage, so that the heating work W ═ P (t + mT) of the cooking appliance in the temperature rising stage can be obtained.
S30, the amount of cooking food to be cooked in the cooking appliance is determined according to the amount of heating work performed by the cooking appliance during the warming-up period.
After the heating work amount W of the cooking appliance in the warming-up stage is obtained, the amount of the cooking food in the cooking appliance can be obtained according to the heating work amount W, because different amounts of food do different amounts of work in the warming-up heating stage, that is, there is a corresponding relationship between the amount of the cooking food and the work done by the cooking appliance in the warming-up heating stage, after the heating work amount of the cooking appliance in the warming-up stage is obtained, the amount of the cooking food in the cooking appliance can be obtained through the corresponding relationship.
In an embodiment of the present invention, the obtaining of the amount of the cooking food in the cooking appliance according to the heating work of the cooking appliance in the warming stage includes: acquiring a heating work-quantity-food-quantity mapping table pre-stored in a cooking appliance; and inquiring a heating work amount-food amount mapping table according to the heating work amount of the cooking appliance in the temperature rising stage, so as to obtain the amount of the cooking food in the cooking appliance.
Specifically, the food amount may be divided into n levels, i.e., C1, C2, …, Cn, which correspond to n corresponding work amounts, i.e., W1, W2, …, Wn, respectively, in this embodiment, the n levels may be recorded in a heating work amount-food amount mapping table, as shown in table 1, it can be understood that the heating work amount-food amount mapping table may be stored in the memory, and after the heating work amount of the cooking appliance in the warming phase is obtained, the processor may query the heating work amount-food amount mapping table stored in the memory to obtain the corresponding food amount, so as to determine the cooking food amount in the cooking appliance. It should be noted that Δ W in table 1 is a predetermined error work of the heating work amount W.
TABLE 1
| Serial number | Work of heating W | Food volume C |
| 1 | W1±△w | C1 |
| 2 | W2±△w | C2 |
| … | … | … |
| n | Wn±△w | Cn |
For example, in a cooking process of a rice cooker, the power used by the cooking appliance to raise the temperature from 30 degrees celsius to 60 degrees celsius in the temperature raising stage is 800 watts, the time is 120 seconds, the standard room temperature set by the cooking appliance is 25 degrees celsius, the current ambient temperature of the cooking appliance is 29 degrees celsius, and the preset coefficient m is 0.5, so that the work performed by the cooking appliance in the stage is W (t + mT) ═ 800 (120+0.5 (29-25)) -97600 joules, 97600 joules are obtained by table lookup in the range of W2 ± Δ W, and therefore, the amount of food in the current cooking appliance can be correspondingly obtained as C2.
In some embodiments of the present invention, in order to prevent some of the heating work amounts from failing to obtain the corresponding food amount in table 1, in this embodiment, the step of querying the pre-stored heating work amount-food amount mapping table according to the heating work amount of the cooking appliance in the warming phase, and further obtaining the cooking food amount in the cooking appliance may further include: firstly, determining a work capacity interval to which the heating work capacity of the cooking appliance belongs in a temperature rise stage; and then inquiring a pre-stored heating work amount-food amount mapping table according to the work amount interval so as to obtain the amount of the cooking food in the cooking utensil.
In summary, the food amount identification method provided by the embodiment of the invention can accurately calculate the food amount in the cooking appliance, and further can match the corresponding subsequent cooking program according to the food amount, so that the food can obtain a better cooking effect, and the taste and the user experience of the cooked food are improved.

S200, adjusting the current cooking curve of the cooking appliance according to the obtained amount of the cooking food in the cooking appliance, and controlling the subsequent cooking of the cooking appliance according to the adjusted cooking curve of the cooking appliance.

In an embodiment of the present invention, the adjusting the current cooking curve of the cooking appliance according to the obtained amount of the cooking food in the cooking appliance may specifically include: an optimal cooking curve is selected according to the amount of cooking food in the cooking appliance and then taken as an adjusted cooking curve.
Optionally, in this embodiment, each food quantity value or range of food quantity values is pre-set with an optimal cooking program, which can be set according to the habits and hobbies of the user, and different cooking programs correspond to different or the same cooking curves. It should be noted that a mapping table may be generated between each cooking curve and the amount of the cooking food and stored in the memory, and after the amount of the cooking food of the cooking appliance is determined, the corresponding optimal cooking curve may be selected from the mapping table, and then the operation of the cooking appliance may be controlled according to the cooking program corresponding to the optimal cooking curve.
It should be noted that, in this embodiment, the cooking curve of the cooking appliance is adjusted when the cooking appliance is in the temperature rise stage, so that the subsequent boiling maintaining stage, the stewing stage and the heat preservation stage in the temperature rise stage can be operated with the optimal cooking curve, and thus the cooking appliance can be controlled to operate with the optimal cooking curve to the greatest extent, and the cooking effect and the user experience are greatly improved.

Fig. 5 is a block diagram illustrating a structure of a food amount recognition apparatus of a cooking appliance according to an embodiment of the present invention.
Further, as shown in fig. 5, the present invention provides an apparatus 100 for identifying an amount of food in a cooking appliance, wherein the apparatus 100 comprises an obtaining module 101, a calculating module 102 and an identifying module 103.
The obtaining module 101 may be configured to, when the cooking appliance is in a temperature rise stage in cooking, obtain a heating parameter of the cooking appliance at this stage and a temperature of an environment where the cooking appliance is currently located; the calculating module 102 may be configured to calculate a heating work amount of the cooking appliance at a temperature raising stage according to a heating parameter of the cooking appliance at the temperature raising stage and a temperature of an environment where the cooking appliance is currently located; the identification module 103 is configured to determine the amount of the cooking food in the cooking appliance according to the heating work of the cooking appliance in the warming phase.
First, it should be noted that the food amount recognition device according to the embodiment of the present invention may be a device installed in a cooking appliance, such as a recognition device installed in a household electric rice cooker, and may also be applied to a commercial electric rice cooker, which is not limited herein.
In this embodiment, a method of recognizing the amount of food will be described by taking rice as an example. In the process of cooking food by a cooking appliance, the food can be generally divided into five stages, namely a water absorption stage, a temperature rise stage, a boiling maintaining stage, a stewing stage and a heat preservation stage, and referring to fig. 5, the food amount recognition device 100 of the present embodiment is applied to the temperature rise stage. Optionally, in this embodiment, a temperature sensor may be disposed on the cooking appliance for monitoring whether the cooking appliance enters a warming stage, that is, the acquiring module 101 in this embodiment includes the temperature sensor. More specifically, the temperature detected by the temperature sensor may be compared with a temperature threshold value, and if the temperature detected by the temperature sensor is greater than the temperature threshold value, it indicates that the cooking appliance starts to enter the warming phase. Similarly, another temperature threshold may be set, and when the temperature detected by the temperature sensor is maintained at the temperature threshold, it indicates that the cooking appliance has ended the warming phase and entered the boiling maintaining phase. It will be appreciated that other sensors may be provided to operate in conjunction with the temperature sensor to monitor various stages of the cooking appliance.
When the cooking appliance is in a temperature rising stage, the obtaining module 101 obtains the heating parameters of the cooking appliance in this stage, specifically, the heating power and the heating time of the cooking appliance in this stage may be obtained, and the temperature of the current environment of the cooking appliance is also obtained. Specifically, in this embodiment, the power detection device in the acquisition module 101 may be used to measure the heating power of the cooking appliance in the temperature-rising stage, and the heating time of the cooking appliance in the temperature-rising stage may be calculated and acquired according to the duration of the cooking appliance in the temperature-rising stage, specifically, the timing module may participate in the calculation, when it is monitored that the cooking appliance enters the temperature-rising stage, the timing module is started to start timing, and then when the cooking appliance exits the temperature-rising stage and enters other stages, the timing module ends timing. The temperature of the environment in which the cooking appliance is located in the embodiment can be detected by arranging a thermometer on the outer insulating and heat-insulating shell of the cooking appliance, and the thermometer is used for displaying the temperature of the environment in which the cooking appliance is located currently. It should be noted that the obtaining units (such as a power detecting device, a temperature sensor, etc.) corresponding to the parameters may be connected to the obtaining module 101 or disposed in the obtaining module 101, so that the temperature of the environment where the cooking appliance is located, and the heating power and the heating time of the cooking appliance in the temperature raising stage can be accurately obtained through the obtaining module 101, and it should be noted that the above example is only used to explain one method of the heating power, the heating time, and the temperature of the environment where the cooking appliance is located in the temperature raising stage, and the data may also be obtained through other methods, which is not limited in the present invention.
Specifically, after the heating power data, the heating time data and the temperature data of the current environment where the cooking appliance is located in the temperature-raising stage of the cooking appliance are acquired by the acquisition module 101, the heating work amount of the cooking appliance in this stage can be calculated by the calculation module 102 according to the acquired data. It should be noted that, in this embodiment, the temperature of the environment where the cooking appliance is located is required to be obtained to calculate the heating work amount of the cooking appliance, so as to improve the calculation accuracy of the heating work, the cooking appliance is generally set to a standard room temperature when being shipped from a factory, the standard room temperature indicates the environment temperature where the cooking appliance is located, that is, the cooking appliance operates at the environment temperature, and other operating parameters of the cooking appliance may be set based on the standard room temperature. It can be understood that the standard temperature corresponding to different cooking appliances may be different, and the standard temperature may also be different for the cooking appliances sold in different places, and in some cooking appliances, a plurality of different standard temperatures may also be set for the user to select.
After the calculation module 102 calculates the heating work amount of the cooking appliance in the temperature-rising stage, the identification module 103 may be reused to identify the amount of the cooking food in the cooking appliance according to the heating work amount, and since different amounts of food perform different amounts of work in the temperature-rising heating stage, that is, there is a corresponding relationship between the amount of the cooking food and the work performed by the cooking appliance in the temperature-rising heating stage, after the calculation module 102 calculates the heating work amount of the cooking appliance in the temperature-rising stage, the identification module 103 may identify and acquire the amount of the cooking food in the cooking appliance according to the corresponding relationship.
In an embodiment of the present invention, the heating parameter may include a heating power and a heating time of the cooking appliance, and the identification module 103 is further configured to calculate a difference between the temperature of the environment where the cooking appliance is located and a preset standard room temperature, correct the heating time of the cooking appliance according to the difference, and obtain a heating workload of the cooking appliance according to the heating power and the corrected heating time.
In an embodiment of the invention, the calculation module 102 may calculate the heating work amount of the cooking appliance in the warming phase according to the following calculation formula: w ═ P (T + mT), where W represents the heating work of the cooking utensil in the temperature rise phase, P represents the heating power of the cooking utensil in the temperature rise phase, T + mT represents the heating time of the cooking utensil after correction, where T represents the heating time of the cooking utensil in the temperature rise phase without correction, m represents a preset coefficient, which is a "temperature difference-time" coefficient, T represents the temperature difference, and T ═ T t –T 0 ，T t Indicating the ambient temperature, T, of the cooking appliance in the current environment 0 Indicating a preset standard room temperature.
In an embodiment of the present invention, the identifying module 103 may identify the amount of the cooking food obtained into the cooking appliance according to the heating work amount of the cooking appliance in the temperature raising stage, and specifically includes: acquiring a heating work-quantity-food-quantity mapping table pre-stored in a cooking appliance; and inquiring a heating work amount-food amount mapping table according to the heating work of the cooking appliance in the temperature rising stage, so as to obtain the amount of the cooking food in the cooking appliance.
Specifically, the food quantity may be first divided into n levels, i.e., C1, C2, …, Cn, which correspond to n corresponding work quantities, i.e., W1, W2, …, Wn, respectively, and in this embodiment, the n levels may be recorded in a heating work quantity-food quantity mapping table, as shown in table 1, it can be understood that the heating work quantity-food quantity mapping table may be stored in the memory, and after the heating work of the cooking appliance in the warming phase is obtained, the processor may be used to query the heating work quantity-food quantity mapping table stored in the memory to obtain the corresponding food quantity, so as to determine the cooking food quantity in the cooking appliance. It should be noted that Δ W in table 1 is a predetermined error work of the heating work amount W.
For example, in a cooking process of a rice cooker, the power used by the cooking appliance to raise the temperature from 30 degrees celsius to 60 degrees celsius in the temperature raising stage is 800 watts, the time is 120 seconds, the standard room temperature set by the cooking appliance is 25 degrees celsius, the current ambient temperature of the cooking appliance is 29 degrees celsius, and the preset coefficient m is 0.5, so that the work performed by the cooking appliance in the stage is W (t + mT) ═ 800 (120+0.5 (29-25)) -97600 joules, 97600 joules are obtained by table lookup in the range of W2 ± Δ W, and therefore, the amount of food in the current cooking appliance can be correspondingly obtained as C2.
In some embodiments of the present invention, in order to prevent some of the heating work amounts from failing to obtain the corresponding food amount in table 1, in this embodiment, the step of querying the pre-stored heating work amount-food amount mapping table according to the heating work amount of the cooking appliance in the warming phase, and further obtaining the cooking food amount in the cooking appliance may further include: firstly, determining a work capacity interval to which the heating work capacity of the cooking appliance belongs in a temperature rise stage; and then inquiring a pre-stored heating work-food amount mapping table according to the work amount interval so as to obtain the amount of the cooking food in the cooking appliance.
It should be noted that, in the present embodiment, other specific implementations of the food amount identification device may refer to the specific embodiments of the food amount identification method in the foregoing embodiments, and are not described herein again.
In summary, the food amount recognition device provided by the embodiment of the invention can accurately calculate the food amount in the cooking appliance, and further can match the corresponding subsequent cooking program according to the food amount, so that the food can obtain a better cooking effect, and the taste and the user experience of the cooked food are improved.
