Meanwhile, food information is identified through the radio frequency signal, and the storage position of the food is recommended through a preset storage recommendation database of the refrigerator. In one embodiment, the storage location of the food may be recommended by voice.
In one embodiment, when a user moves food from the refrigerator compartment to the freezer compartment, the radio frequency reader first determines whether the food has moved; if it is determined that the food item is actually moved, the position detecting member detects the current storage position of the food item. When the current position of the food is obtained, whether the food is moved to the recommended storage position is further judged by comparing the recommended positions recorded in the stored recommended data. When the food is not stored in the recommended position, the user is reminded, for example, the food is reminded in a voice broadcast mode.
In one embodiment, when the user takes the food out of the refrigerator, the refrigerator determines whether the rf signal corresponding to the food can be detected by the rf reader. And when the food is not detected, deleting the information corresponding to the food from the refrigerator system.
