For example, when the user opens the door 101 of the refrigerator, the control module 180 controls the color sensor 130 to collect color information at the access position 110 of the preset identification device in real time according to the opening state information of the door 101 detected by the door state detection module 170. At this time, if a user wants to store eggs in the refrigerator 100, the identification device 120 with the egg identification can be directly accessed from the preset identification device access location 110, and the identification device 120 is attached to the eggs and placed in the refrigerator 100. If the background color at the preset identification device access position 110 is white and the color of the identification device 120 with the egg identification is green, when the user takes out the identification device 120 with the egg from the preset identification device access position 110, the color information detected by the color sensor 130 changes from green to white, that is, the color information acquired by the color sensor 130 changes from the identification color information to the preset background color information, at this time, the processing module 160 may identify the access action type corresponding to the identification device 120 with the color of green as a take-out action according to the change of the color information, that is, the user takes out the identification device 120 with the identification color of green from the preset identification device access position 110. The identification color information-food material information list stored in the storage module 150 can be queried according to the color information of the identification device 120, the food material information associated with the identification device 120 with the green identification color is obtained, and the food material information is added to the food material storage list and displayed through the display screen 102 on the refrigerator 100. When the user takes out all eggs in the refrigerator 100, at this time, the identification device 120 attached to the egg is picked off and placed back to any one of the preset identification device access positions 110, the color information collected at the preset identification device access position 110 changes from white information to green information, the processing module 160 determines again according to the color change that the identification device 120 with the green identification color is placed back to the preset identification device access position 110, and queries again according to the color information the identification color information-food material information list in the storage module 150 to obtain the food material information associated therewith, and deletes the food material information from the food material storage list.
Certainly, when the user wants to store eggs in the refrigerator 100, the user may also directly select the identification device 120 that does not represent any food material, for example, the user takes out the identification device 120 with a red identification color, and when the processing module 160 obtains the color information of the identification device 120 and the corresponding access action type is a taking action according to the color information, a prompt box may be directly popped up at the screen end to prompt the user to input the food material information stored in the refrigerator 100, and the user may input the food material name in the modes of the screen end, voice input, and the like: eggs; shelf life: 15 days and the like, the storage module 150 stores the information input by the user and establishes a corresponding identification color information-food material information list. Meanwhile, the related food material information can be added to the food material storage list and displayed through the display screen 102. When it is detected that the identifier 120 with the green identifier color is placed back to the preset identifier access location 110, the identifier color information-food material information list in the storage module 150 is queried according to the color information, and the information is deleted from the storage module 150 and the food material storage list, so that when the user takes the identifier 120 again, the user can autonomously input food material information according to the latest accessed food material.
In summary, the food material management module and the refrigerator 100 provided by the invention have the advantages that the identification device 120 and the color sensor 130 are arranged to acquire the change of the food material information in the refrigerator 100, the structure is simple, the cost is low, and the identification accuracy is high.
