Refrigerator and control method thereof

Abstract

The invention discloses a refrigerator and a control method thereof. The refrigerator includes a casing; a refrigerator door; an RFID module includes a reader and a label box; and a controller is configured to: read each label in the label box according to the reader serial code, monitor user operation; in response to the user operation, obtain operation information and ingredient information corresponding to the target serial code; the operation information includes operation type and location information; according to the operation information and the ingredient information, Generate an operation record corresponding to the target sequence code, and record the operation record into the access record database; change the storage state of the label corresponding to the target sequence code in the label database. This application adopts the RFID module to realize the independent perception of RFID, which makes little modification to the structure of the refrigerator and reduces the manufacturing cost. At the same time, it can realize the automatic entry of relevant information about the user's access to food materials, as well as the automatic update and management of the label database, which improves the intelligence of the refrigerator. and user experience.

Description

technical field [0001] The invention relates to the technical field of smart home appliances, in particular to a refrigerator and a control method thereof. Background technique [0002] Refrigerators are commonly used electrical equipment in daily life. By cooling the ingredients, such as refrigerating or freezing, the preservation and storage of ingredients can be realized. Users can store ingredients in the refrigerator or take out the required ingredients from the refrigerator. By selecting the types of ingredients, Information such as the storage location of ingredients can be identified and entered, which can realize the intelligent management of refrigerators. [0003] At present, Radio Frequency Identification (RFID) technology has been gradually applied to smart refrigerators, and its principle is to identify objects through non-contact data communication between readers and electronic tags. At present, common RFID refrigerators generally install RFID antennas in mu...

Problems solved by technology

[0004] However, this method requires a large structural modification of the refrigerator, and more RFID antennas need to be arranged. Refrigerators with different volumes require different sizes of RFID antennas. The development costs of RFID antennas of different sizes are high, and signal shielding processing is required between RFID antennas. The process is complicated and the cost is high
