Wherein, the compression process is as follows: the power cord of the refrigerator is plugged, and under the condition that the contact of the temperature controller is connected, the compressor starts to work, the low-temperature and low-pressure refrigerant is sucked by the compressor, and is compressed into high-temperature and high-pressure superheated gas in the cylinder of the compressor and then is discharged into the condenser; the condensation process is as follows: the high-temperature and high-pressure refrigerant gas is radiated by the condenser, the temperature is continuously reduced, the refrigerant gas is gradually cooled to be saturated vapor with normal temperature and high pressure, the refrigerant gas is further cooled to be saturated liquid, the temperature is not reduced any more, the temperature at the moment is called as the condensation temperature, and the pressure of the refrigerant in the whole condensation process is almost unchanged; the throttling process is as follows: the condensed saturated liquid of the refrigerant flows into a capillary after moisture and impurities are filtered by a drying filter, throttling and pressure reduction are carried out through the capillary, and the refrigerant is changed into wet steam with normal temperature and low pressure; the evaporation process is as follows: the normal temperature and low pressure wet steam starts to absorb heat to vaporize in the evaporator, so that the temperature of the evaporator and the surrounding temperature of the evaporator are reduced, the refrigerant is changed into low temperature and low pressure gas, the refrigerant from the evaporator returns to the compressor after passing through the gas-liquid separator, the processes are repeated, the heat in the refrigerator is transferred to the air outside the refrigerator, and the aim of refrigeration is fulfilled.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a refrigerator 100 according to an embodiment of the present invention, where the refrigerator 100 includes:
the induction system 10 comprises an antenna arranged on the refrigerator door body and is used for inducing the electronic tag;
the display device 20 is arranged on the refrigerator door body and used for displaying data and receiving an operation instruction of a user;
the controller 30 is configured to:
in response to the approach operation of the electronic tag, judging the storage information of the current electronic tag; the electronic tags comprise custom tags and predefined tags;
when the storage information of the current electronic tag is stored in the refrigerator, controlling a display device to display an operation interface corresponding to the food material taking-out operation;
when detecting that the storage information of the current electronic tag is not stored in the refrigerator, controlling a display device to display an operation interface corresponding to food material storage operation;
and receiving the user operation acquired by the operation interface, and executing a corresponding operation process.
It should be noted that the electronic tag is an RFID tag or an NFC tag, when the electronic tag configured for the refrigerator 100 is an RFID tag, the sensing system is a sensing system corresponding to the RFID tag, and when the electronic tag configured for the refrigerator 100 is an NFC tag, the sensing system is a sensing system corresponding to the NFC tag. The RFID tag adopts Radio Frequency Identification (RFID), performs non-contact bidirectional data communication in a Radio Frequency mode, reads and writes a recording medium (an electronic tag or a Radio Frequency card) in the Radio Frequency mode so as to achieve the purposes of identifying a target and exchanging data, combines the Radio Frequency Identification with a data access technology through Radio wave non-contact quick information exchange and storage technology, and then is connected with a database system so as to achieve the non-contact bidirectional communication, thereby achieving the purpose of Identification, being used for data exchange and being connected in series to form an extremely complex system. The NCF tag adopts the technical principle of near field communication, and can exchange data in an active mode and a passive mode. In the passive mode, the device that starts near field communication, also called the initiator (master), provides a radio frequency field (RF-field) during the whole communication process, and it can select one of the transmission speeds of 106kbps, 212kbps or 424kbps to transmit data to another device, called the target (slave), without generating the RF field, but uses load modulation (load modulation) technique to transmit data back to the initiator at the same speed, while in the active mode, both the initiator and the target generate their own RF fields to communicate.
For example, referring to fig. 2, fig. 2 is a schematic view of interaction between an electronic tag and a refrigerator provided in an embodiment of the present invention, which is described by taking an NFC tag as an example, when the sensing system 10 detects that the NFC tag is close to the refrigerator, it is first necessary to determine the type of the NFC tag, where the custom tag is an electronic tag capable of editing a name of a food material, the predefined tag is an electronic tag incapable of editing a name of a food material, and storage dates, expiration dates, quantities, and storage locations of the custom tag and the predefined tag can be edited. After the type of the electronic tag is judged, detecting storage information of the NFC tag in the refrigerator 100, and when it is detected that the storage information of the NFC tag is stored in the refrigerator, indicating that the user takes out food at this time, controlling the display device 20 to display an operation interface corresponding to an operation of taking out food at this time; when the storage information that the NFC tag is not stored in the refrigerator is detected, it is indicated that the user needs to store food materials, and at the moment, the display device 20 is controlled to display an operation interface corresponding to food material storage operation.
Further, for a custom tag, when a fetching operation is performed, the storage information in the custom tag needs to be deleted, and the custom tag is restored to a blank tag. When the custom tag is stored in the refrigerator 100, a situation of a non-blank tag may be detected, and when the user edits half of the custom tag, the custom tag may not be stored in the refrigerator, and at this time, a situation of a non-blank tag not stored in the refrigerator may occur, and the user may continue to edit the custom tag last time, or edit the custom tag again after deleting the information.
Further, the controller 30 is further configured to:
when the refrigerator door body is detected to be switched from the opening state to the closing state, acquiring the induction condition of the induction system when the refrigerator door body is switched from the closing state to the opening state last time;
if the induction system does not respond to the approach operation of the electronic tag in a first time period before the refrigerator door body is opened and does not respond to the approach operation of the electronic tag in a second time period after the refrigerator door body is closed, sending a prompt message; and the prompt information stops sending when the preset stopping condition is met, wherein the stopping condition is that a stopping response control instruction of a user is received or the prompting time of the prompt information is reached.
