All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a refrigerator according to an embodiment of the present invention, where the refrigerator includes:
a cabinet 10 serving as a support structure of the refrigerator and having a plurality of storage compartments therein;
the controller 20 is configured to:
when detecting that a current label is taken out of a label box, deleting the current label from a first label set corresponding to the label box; the tag box is used for storing tags which are not bound with food materials, an RFID reader-writer used for detecting the current tags is arranged in the tag box, and the tags are RFID tags;
responding to the binding operation of the current food material, and acquiring a second tag set of tags bound with the food material;
when the current label does not exist in the second label set, adding the current label into the second label set;
and acquiring the adding time of the second label added into the second label set, and monitoring the quality guarantee period of the current food material corresponding to the current label based on the adding time.
Specifically, in the embodiment of the present invention, the label box is disposed in one of the storage chambers of the refrigerator or outside the refrigerator. It is understood that when the tag box is disposed in the storage chamber, in order to avoid confusion with other tags bound to food materials in the storage chamber, the tag and the tags need to be separated from the tags in the storage chamber, a special RFID reader/writer is provided in the tag box for recording changes of the tags in the tag box, and the tag box is made of a special material so that the tags outside the tag box cannot be detected by the RFID reader/writer. Likewise, when the tag box is located outside the refrigerator, the change of the tag is recorded by means of a special RFID reader in the tag box.

For example, the adding time may reflect when a user starts to store food, and after the adding time is obtained, the food material information of the current food material is recorded according to the current tag, and an optimal shelf life corresponding to the current food material information is obtained, where the optimal shelf life may be set by the user, or obtained in real time from a database through the controller 20, for example, the current food material is a tomato, and at this time, the optimal shelf life may be 3 days specified by the user, or the controller 20 may obtain the optimal shelf life of the tomato from the database. It can be understood that the database may store optimal shelf lives corresponding to a plurality of food materials, each of the optimal shelf lives has a corresponding storage temperature, when the controller 20 obtains the optimal shelf life, the controller may obtain the corresponding optimal shelf life according to the current temperature of the storage room where the current food material is located, and when the current temperature of the storage room changes, the optimal shelf life also changes correspondingly.
After the optimal quality guarantee period is obtained, the optimal quality guarantee period is used as the storage time length, the quality guarantee time corresponding to the adding time and the storage time length is calculated in real time, for example, if the storage time length is 3 days, the quality guarantee time is the accumulated time of the adding time and the storage time length. And monitoring the current food material according to the quality guarantee time, and when the current time is greater than the quality guarantee time, indicating that the current food material is stored for a long time, and sending prompt information to remind a user of processing as soon as possible.
Specifically, when it is detected that a new tag is inserted into the tag box, it indicates that the user has taken out food from the refrigerator at this time, and inserts a tag bound to the food into the tag box, at this time, the controller adds the new tag to the first tag, and deletes the new tag from the second tag.
Specifically, after the second tag set is acquired in response to the binding operation of the current food material, when it is detected that the current tag exists in the second tag set, it indicates that the second tag set is not deleted when the tag is taken out last time, and at this time, only the adding time of the current tag in the second tag set needs to be updated.
Compared with the prior art, the refrigerator disclosed by the embodiment of the invention provides the label box for storing the labels which are not bound with the food materials, the label box can be arranged in a certain compartment in the refrigerator or placed outside the refrigerator, the labels which are not bound with the food materials are represented by the first label set, meanwhile, the labels which are bound with the food materials are represented by the second label set, when the labels are changed, the information of the changed labels can be counted quickly, and the adding time of the labels added into the second label set is taken as the storage time of the current food materials, so that the quality guarantee period of the current food materials is monitored, and the quality guarantee period of the food materials is monitored. In addition, the tags are counted in a set form, so that the food materials can be managed in a unified mode, and unified monitoring of the food materials is facilitated.
