Title: METHOD FOR AUTOMATICALLY DISPLAYING DEGREE OF FRESHNESS OF PACKAGED FOOD, AND REFRIGERATOR
Abstract:
A method for automatically displaying the degree of freshness of packaged food, and a refrigerator. The method comprises: recording a food type pattern and a prompt colour related to a shelf life (S101); reading a barcode of packaged food to be put into a refrigerator, and identifying a food category, a production date and a shelf life thereof (S102); associating prompt colours corresponding to the food type pattern and the shelf life (S103); and displaying the food type pattern and the prompt colour corresponding thereto according to the food category and the shelf life, and updating the prompt colour at midnight every day (S104). In the method, by means of reading a barcode of packaged food to be put into a refrigerator, associating prompt colours with the food type pattern and a shelf life corresponding thereto, and updating and displaying the prompt colour corresponding to the shelf life thereof on a display screen outside of the refrigerator, a user can intuitively know the degree of freshness of the packaged food in the refrigerator.
