Method for judging freshness of food materials of refrigerator, refrigerator and storage medium

Abstract

The invention provides a method for judging the freshness of the food materials of a refrigerator, the refrigerator and a storage medium. The freshness of the food is detected through spectral analysis, and a freshness model is established, so that the detection result of the freshness is more accurate; the relationship among food-freshness-spectral data is determined, so that the relationship between the freshness model and the food freshness is well matched, and real-time adjustment can be made according to the use of a user, so that the judgment of the freshness is more accurate after multiple iterations and conforms to the cognition of the user on the freshness. The problem that the subjective standard of freshness cannot be judged due to different cognition of different customers is solved, and higher intelligence of the refrigerator is achieved.

Description

technical field [0001] The invention relates to the field of refrigeration equipment, in particular to a method for judging the freshness of ingredients in a refrigerator, a refrigerator and a storage medium. Background technique [0002] Refrigerators are used to store food and provide freshness preservation. However, the preservation of refrigerators is not unlimited. After long-term storage, it will be stale or even deteriorated. Customers often cannot perceive the changes of food in the refrigerator in time. When some ingredients are forgotten to eat Finally, when preparing to eat after a period of time, it is found that it has deteriorated and can only be discarded, causing waste and inconvenience to use. [0003] There are existing patents for judging the freshness by detecting the smell, but there are many defects, such as the deterioration of some foods without obvious smell changes, such as green vegetables with little smell gradually turning yellow, or green onions...

Problems solved by technology

[0002] Refrigerators are used to store food and provide freshness preservation. However, the preservation of refrigerators is not unlimited. After long-term storage, it will be stale or even deteriorated. Customers often cannot perceive the changes of food in the refrigerator in time. When some ingredients are forgotten to eat Finally, after a period of time when it is ready to eat, it is found that it has deteriorated and can only be discarded, causing waste and inconvenience to use

[0003] There are existing patents for judging the freshness by detecting the smell, but there are many defects, such as the deterioration of some foods without obvious smell changes, such as green vegetables with little smell gradually turning yellow, or green onions and garlic with strong smell gradually drying or rotten , the smell itself does not necessarily change significantly, which causes the problem of inaccurate freshness detection

[0004] In addition, freshness is a subjective concept. Different people have different perceptions of freshness. If the refrigerator’s judgment on freshness cannot vary from person to person, there will be food that is judged fresh by the refrigerator, or that most people think is fresh. , not fresh to a small number of people; even for some different foods, different people's perception of freshness is just the opposite, making it impossible to use a freshness standard to complete the refrigerator's judgment of freshness, which restricts the intelligence of the refrigerator , does not meet the needs of smart homes
