In an embodiment of the present invention, the determining second concentration information of the odorant in the cooking cavity according to the first concentration information of the odorant includes: and calculating the concentration of the odor substance in the gas before compression according to the first concentration information of the odor substance and the compression ratio of the gas during compression to obtain second concentration information of the odor substance in the cooking cavity. It is noted that the first concentration information of the odorant represents concentration information of the odorant for characterizing food doneness in the gas after compression, and the second concentration information of the odorant represents concentration information of the odorant for characterizing food doneness in the gas before compression.
And S14, detecting the food maturity of the food in the current cooking cavity according to the second concentration information.
In an embodiment of the present invention, the detecting the food maturity of the food in the current cooking cavity according to the second concentration information includes: judging whether the second concentration information meets a concentration threshold corresponding to the set food maturity; and when the second concentration information meets a concentration threshold corresponding to the set food maturity, judging that the food is mature.

According to the method and the device for detecting the maturity of the food, the cooking appliance and the storage medium, provided by the embodiment of the invention, when the cooking appliance operates a cooking function, gas emitted by the food in the cooking cavity is obtained; compressing the collected gas, and determining second concentration information of the odor substance in the cooking cavity according to first concentration information of the odor substance for representing the maturity of the food in the compressed gas; according to the method and the device, the collected gas is compressed, so that the concentration of smell substance molecules in the gas in unit volume can be improved, the detection precision of the concentration of the smell substance in the gas can be further improved, and the effect of accurately judging the food maturity of the food in the cooking cavity according to the concentration of the smell substance in the cooking cavity is achieved.
Fig. 2 shows a specific flowchart of a method for detecting food maturity according to an embodiment of the present invention. As shown in fig. 2, when the cooking appliance operates a cooking function, the air pump is started to pump the air in the cooking cavity to realize air collection, the collected air in the cooking cavity is conveyed to the compression cavity of the air compression device, the compression pump of the air compression device is started to compress the air in the compression cavity, and meanwhile, first concentration information of the odor substance for representing the degree of ripeness of the food in the compressed air is detected. In this embodiment, the air pressure in the compression chamber is detected by the air pressure detection device, and when the air pressure reaches the preset pressure threshold range, the compression operation is stopped. At the moment, the gas pressure of the compression cavity needs to be controlled, the phenomenon that the detection effect of the concentration information of the odor substances is poor due to too small gas pressure and the corresponding concentration threshold value cannot be reached is avoided, the gas pressure detection device is damaged due to too large gas pressure, and the preset pressure threshold value range is controlled to be 2-2.5 times of the atmospheric pressure and is suitable through research. When the air pressure in the compression cavity reaches 2-2.5 times of the preset air pressure, the odor detection device is started, and the operation of detecting the first concentration information of the odor substance for representing the food maturity in the compressed air is executed. The odor detection device can output different voltage signals according to the first concentration information of different odor substances detected after compression, and amplify the voltage signals so as to perform data processing and data restoration subsequently.

Further, a corresponding judgment result is given to the maturity of the food according to a concentration threshold value corresponding to the set maturity of the food, and if the second concentration information meets the concentration threshold value corresponding to the set maturity of the food, the maturity of the food is judged, the cooking is stopped, and the intelligent cooking process is completed; if the second concentration information does not meet the concentration threshold corresponding to the set food maturity, continuing to cook the food in the cooking cavity until the detected second concentration information meets the concentration threshold corresponding to the set food maturity, ending the cooking and completing the intelligent cooking process. Wherein, the set concentration threshold corresponding to the food maturity is the combination of the concentration thresholds of the multiple chemical substances.
It can be understood that, before the cooking appliance runs the cooking function, the user can select the set food maturity to start the cooking function, wherein the set food maturity can correspond to different food tastes, and the three food tastes including tender, standard and burnt are available for the user to select. After the cooking appliance starts the cooking function, heating the food in the cooking cavity based on a preset temperature and time control strategy. The specific gas components are the various chemical substances and comprise odor substances of different types, specifically alcohols, tinctures and the like, the types of the odor substances corresponding to different food types are different, and the concentrations of the odor substances corresponding to different maturity states are different, so that the maturity of the food can be represented by detecting the concentration of the odor substances in the gas emitted by the food in the cooking process.
In the embodiment of the present invention, the temperature and time control strategy includes: the heating process is controlled according to different heating temperatures and heating times, and the heating temperature and the heating time are set according to the type of the food. For example, when the food to be cooked is leek, the heating temperature can be set to be lower and the heating time can be set to be shorter, and when the food to be cooked is chicken wings, the heating temperature can be set to be higher and the heating time can be set to be longer. In practical applications, for specific value settings of the heating temperature and the heating time, a temperature time control curve may be generated by verifying and accumulating corresponding data through a large number of experiments to provide a temperature time control strategy for a heating process of the cooking appliance during the operation of the cooking function, which is not specifically limited in the present invention.
In the embodiment of the invention, the type information of the odor substances used for representing the food maturity in the gas can be obtained by establishing a mapping relation table, wherein the mapping relation table comprises the corresponding relation between common food types and the odor substances corresponding to the food types, and the corresponding relation between the same food type, different food maturity and the concentration of the odor substances corresponding to the different food maturity. And obtaining a concentration threshold value corresponding to the set food maturity according to the mapping relation table.
The method for detecting the food maturity provided by the embodiment of the invention is an innovative gas collecting and calculating method, the accuracy of the sensor for detecting the molecular concentration of the odor substance is improved by properly compressing the collected gas, and then the concentration of the odor substance in the originally collected gas is reduced by an algorithm, so that whether the concentration of the odor substance meets a concentration threshold value corresponding to the set food maturity can be more accurately judged, and the food maturity is further judged; under the condition that gas sensor's detection precision promoted, no longer only be limited to the judgement whether food is burnt, can also realize carrying out more accurate judgement to food maturity, satisfy the intelligent requirement of user to cooking utensil.
