For convenience of description, unless otherwise specified, the directions of upper, lower, left, right, front and rear directions of the present disclosure are all referred to a state of the refrigerator in use. The refrigerator is characterized in that a side facing a user in use is a front side, and the opposite side is a rear side. The height direction of the refrigerator is the up and down direction. The left-right direction of the refrigerator is opposite to the left-right direction of the user, for example, the left side of the refrigerator is the right side of the user, and the right side of the refrigerator is the left side of the user.

In family life, the refrigerator can prolong the shelf life of food materials, but the food materials can be deteriorated after being stored in the refrigerator for too long. In general, a user can judge the freshness of the food by observing the appearance or smell of the food.

However, when the variety of food materials stored in the refrigerator is more, the food materials are mutually shielded, so that the observation of a user can be influenced; in addition, the multiple food materials can release multiple odors, and after the multiple odors are mixed together, a user cannot distinguish the specific situation of each food material.

To this end, some embodiments of the present disclosure provide a refrigerator 1000, as shown in fig. 1 and 2, the refrigerator 1000 includes a cabinet 100 and a door 200. The case 100 includes a storage space, and the door 200 is configured to open and close the storage space.

In some embodiments, the storage space includes a refrigerating compartment 110 and a freezing compartment 120. The refrigerating chamber 110 may maintain the temperature of the air therein between about 0 c to 5 c and store food in a refrigerating mode. The freezing chamber 120 may maintain the temperature of its internal air between about-30 c to 0 c and store food in a freezing mode.

In some embodiments, the refrigerating compartment 110 and the freezing compartment 120 are aligned in the height direction of the refrigerator 1000. For example, the refrigerating compartment 110 is located below the freezing compartment 120. It should be noted that, in some embodiments, the refrigerating chamber 110 and the freezing chamber 120 may be arranged in other manners, which is not limited in this disclosure.

In some embodiments, referring to fig. 2, the enclosure 100 also includes other chambers, such as a temperature swing chamber 130 (i.e., a fresh food chamber), and the like. The variable temperature chamber 130 is disposed between the refrigerating chamber 110 and the freezing chamber 120, for example.

In some embodiments, the door body 200 includes a refrigerating compartment door 210 and a freezing compartment door 220, the refrigerating compartment door 210 pivotally opening or closing the refrigerating compartment 110, and the freezing compartment door 220 pivotally opening or closing the freezing compartment 120.

For example, the refrigerator 1000 includes two refrigerating compartment doors 210 and two freezing compartment doors 220. When it is required to close the refrigerating compartment 110, the two refrigerating compartment doors 210 are respectively rotated in directions approaching each other, and when it is required to open the refrigerating compartment 110, the two refrigerating compartment doors 210 are respectively rotated in directions separating from each other. When it is desired to close the freezing chamber 120, the two freezing chamber doors 220 are respectively rotated in directions approaching each other, and when it is desired to open the freezing chamber 120, the two freezing chamber doors 220 are respectively rotated in directions separating from each other.

In some embodiments, the refrigerator 1000 further includes a drawer 300, and the drawer 300 is inserted in the storage space to define the storage compartment (e.g., the refrigerating compartment 110, the freezing compartment 120, or the temperature changing compartment 130).

In some embodiments, as shown in fig. 3, the refrigerator 1000 further includes a refrigeration system 400. The refrigeration system 400 includes a compressor 410, a condenser 420, an anti-condensation pipe 430, a dry filter 440, a capillary tube 450, an evaporator 460, a gas-liquid separator 470, a connection line 480, and a refrigerant flowing in the connection line 480. The operation of the refrigeration system 400 includes a compression process, a condensation process, a throttling process, and an evaporation process. The compressor 410, the condenser 420, the anti-condensation pipe 430, the dry filter 440, the capillary tube 450, the evaporator 460 and the gas-liquid separator 470 are communicated through a connecting pipe 480.

The compression process comprises the following steps: when the refrigerator 1000 is powered on, the compressor 410 starts to operate. The low-temperature low-pressure refrigerant is sucked into the compressor 410, compressed into a high-temperature high-pressure superheated gaseous refrigerant in the cylinder of the compressor 410, and discharged to the condenser 420.

The condensation process comprises the following steps: the high temperature, high pressure superheated gaseous refrigerant dissipates heat in condenser 420, is cooled first to normal temperature, high pressure saturated vapor, and then further cooled to saturated liquid, with the refrigerant pressure being nearly unchanged during condensation.

The throttling process comprises the following steps: the saturated liquid flows into the capillary tube 450 after the moisture and impurities are filtered by the dry filter 440, and the refrigerant is changed into wet vapor at normal temperature and low pressure by throttling and depressurization through the capillary tube 450.

The evaporation process comprises the following steps: the normal temperature, low pressure wet vapor is vaporized by heat absorption in the evaporator 460 to reduce the temperature of the evaporator 460 and its surrounding environment and to change the refrigerant into a low temperature, low pressure gas. The refrigerant discharged from the evaporator 460 passes through the gas-liquid separator 470 and returns to the compressor 410.

It will be appreciated that the refrigeration system 400 may transfer heat within the refrigerator 1000 to the outside of the refrigerator 1000 by repeatedly performing the above process, thereby achieving the purpose of refrigeration.

In some embodiments, as shown in fig. 4, the refrigerator 1000 further includes a blower 490 and an air duct 491. The blower 490 is configured to flow air in the refrigerator 1000, to heat-exchange the air into the fins of the evaporator 460, and to send the heat-exchanged cool air into the refrigerating compartment 110 and the freezing compartment 120 through the air duct 491, so that the temperatures in the refrigerating compartment 110 and the freezing compartment 120 can be reduced.

In some embodiments, as shown in fig. 5, the refrigerator 1000 further includes a first antenna 500 and an electronic tag 600. The first antenna 500 is disposed in the storage compartment of the refrigerator 1000 and is communicatively connected to the electronic tag 600. The first antenna 500 is configured to transmit a wireless signal to the electronic tag 600 or receive a wireless signal transmitted from the electronic tag 600 (e.g., to receive information such as an electric quantity value, an odor detection value, etc. transmitted from the electronic tag 600).

Referring to fig. 9, the electronic tag 600 includes an odor detection part 610. The odor detection index of the food material to be detected (i.e., the food material having a binding relationship with the electronic tag 600) is written in advance in the odor detection section 610. The odor detection component 610 is configured to detect in real time the odor emitted by the food material to be detected.

In some embodiments, when the first antenna 500 senses the electronic tag 600, the electronic tag 600 is in the first state. When the electronic tag 600 is in the first state, the electronic tag 600 is located in the storage compartment and is bound with the food to be detected, and no other food is placed in the storage compartment, so that the odor detection component 610 in the electronic tag 600 can detect the odor of the food to be detected.

In some embodiments, as shown in fig. 6, the refrigerator 1000 further includes a first label box 700, the first label box 700 being detachably disposed in the case 100, for example, the first label box 700 being detachably disposed in the storage compartment. The first cassette 700 includes a second antenna 710, a plurality of storage locations 720, and a plurality of pressure sensors 730 disposed on the plurality of storage locations 720.

The second antenna 710 is configured to transmit a wireless signal to the electronic tag 600 placed in the first tag box 700 or to receive a wireless signal emitted from the electronic tag 600. The storage location 720 is configured to place the electronic tag 600. Each storage location 720 corresponds to a food material (such as meats, fruits, vegetables, etc.), and stores in advance an odor detection index corresponding to the food material. The pressure sensor 730 is configured to detect a pressure value on its corresponding storage location 720.

In some embodiments, when the second antenna 710 senses the electronic tag 600 and the first antenna 500 does not sense the electronic tag 600, the electronic tag 600 is in the second state. When the electronic tag 600 is in the second state, the electronic tag 600 is stored in any one of the plurality of storage locations 720.

For example, the first cassette 700 also includes a housing 701, the housing 701 being constructed of a shielding material (e.g., metal, etc.). Thus, when the electronic tag 600 is in the second state, i.e., when the electronic tag 600 is stored in the first tag box 700, the second antenna 710 may sense the electronic tag 600, and the first antenna 500 may not sense the electronic tag 600.

In some embodiments, as shown in fig. 5, the refrigerator 1000 further includes a controller 1, the controller 1 being communicatively coupled to the first antenna 500 and the first tag cassette 700, respectively. When the user places the electronic tag 600 on any storage position 720, the controller 1 writes the odor detection index of the food corresponding to the current storage position 720 into the electronic tag 600, so that the user does not need to edit the electronic tag 600 by means of the antenna on the door body 200, and the editing step of the electronic tag 600 can be simplified.

For example, the controller 1 may be a micro control unit (Microcontroller Unit, MCU) or a central processing unit (Central Processing Unit, CPU).

In some embodiments, the electronic tag 600 is a radio frequency identification (Radio Frequency Identification, RFID) tag or a Near Field Communication (NFC) tag.

For example, when the electronic tag 600 is the rfid tag, the first antenna 500 and the second antenna 710 are antennas corresponding to the rfid tag. For example, when the electronic tag 600 is the near field communication tag, the first antenna 500 and the second antenna 710 are antennas corresponding to the near field communication tag.

The rfid tag performs non-contact bidirectional data communication in a wireless radio frequency manner, and reads and writes a recording medium (e.g., the electronic tag 600 or the radio frequency card) in a wireless radio frequency manner, thereby achieving the purpose of identification and data exchange. The wireless radio frequency identification technology performs rapid information exchange and storage through radio waves, and is connected with a database system through wireless communication and data access technology, so that non-contact bidirectional communication is realized.

The near field communication tag exchanges data through both active and passive modes. In a passive mode, a near field communication device (i.e. an initiating device, i.e. a master device) is activated to provide a radio frequency field (RF-field) and to transmit data to another device (i.e. a target device, i.e. a slave device) via the radio frequency field at a first transmission speed, and then the target device transmits data back to the initiating device via load modulation (load modulation) techniques at substantially the same speed as the first transmission speed. For example, the first transmission speed is 106kbps, 212kbps or 424kbps. In the active mode, the initiating device and the target device both generate respective radio frequency fields for communication.

In some embodiments, referring to fig. 7, refrigerator 1000 establishes a data connection with a client 103 (e.g., a smart phone or tablet computer, etc.) through router 101 or cloud server 102.

Illustratively, when the refrigerator 1000 communicates with the client 103 through the router 101, the refrigerator 1000 is closely spaced from the client 103, so that a user can view the operation condition of the refrigerator 1000 placed in a kitchen and the food storage condition in a living room or a room.

Or when the refrigerator 1000 communicates with the client 103 through the cloud server 102, the refrigerator 1000 is far away from the client 103, and a user may perform data interaction with the refrigerator 1000 through an APP (Application) installed in the client 103, or remotely control the refrigerator 1000.

In some embodiments, the controller 1 is configured to perform steps 11 to 14.

In step 11, the controller 1 receives the odor detection value of the food material to be detected, which is detected by the odor detection section 610 according to the odor detection index, through the first antenna 500.

In some embodiments, the odor detection component 610 includes an odor sensor. When the odor sensor works in a clean air environment, setting the resistance value of the sensitive resistor (Rs) of the odor sensor as a reference resistance value (R0), and when detected gas exists in the air, changing the resistance value of the sensitive resistor of the odor sensor along with the change of the conductivity of the semiconductor material. Thus, the concentration of the detected gas can be calculated in a mapping manner by calculating the ratio of the resistance value of the sensitive resistor to the reference resistance value.

As shown in fig. 8, the sensitivity of the sensitive resistor to various odors (e.g., alcohol, ammonia, methane, hydrogen sulfide, etc.) is different. Therefore, when monitoring food materials, it is necessary to determine the odor detection index corresponding to the food materials, and then select the odor to be monitored by the odor sensor.

For example, when the food material to which the electronic tag 600 is bound is meat, the odor detection index of the food material may be set to be hydrogen sulfide and ammonia water, so that the odor detection part 610 only needs to collect the detected values of the two odors, hydrogen sulfide and ammonia water, and send them to the controller 1.

In step 12, the controller 1 compares the odor detection value with a standard odor value pre-stored in the controller 1 to obtain a comparison result.

In step 13, the controller 1 determines whether the electronic tag 600 bound to the food material to be detected meets the preset food material odor condition according to the comparison result, if yes, step 14 is executed, and if not, step 11 is executed again.

Illustratively, the food material odor conditions include: the odor detection value is greater than the corresponding standard odor value. The controller 1 stores in advance standard odor values corresponding to a plurality of different food materials, compares the standard odor values with the odor detection values detected by the odor detection unit 610 in real time, and if the odor detection values are greater than the standard odor values, indicates that the food materials have deteriorated. For example, when the real-time odor detection value of the odor detection index (i.e., hydrogen sulfide and ammonia water) corresponding to the meat food material is greater than the standard odor value, it indicates that the meat food material has deteriorated.

It should be noted that, the electronic tag 600 and the food material to be detected corresponding to the electronic tag are stored in the same storage space, and another food material does not exist in the storage space.

In step 14, the controller 1 issues a prompt.

For example, the prompt message may be a short message sent by the controller 1 to the client 103 to alert the user that the food in the refrigerator 1000 may have deteriorated. Or the refrigerator 1000 further includes a display, for example, provided on a side surface of the door body 200 remote from the case body 100, and the controller 1 may transmit the prompt information to the display and display the deterioration of the food material by the display. Thus, the user can quickly find the deterioration condition of the food material and process the food material, so that the deteriorated food material does not pollute the refrigerator 1000 and other food materials in the refrigerator 1000.

In some embodiments, the controller 1 is further configured to perform steps 21 to 24.

In step 21, the controller 1 receives a plurality of pressure values on a plurality of storage locations 720 detected by a plurality of pressure sensors 730.

In step 22, the controller 1 calculates the amounts of change in the plurality of pressure values within a first preset time.

Illustratively, the plurality of pressure sensors 730 in the first label box 700 are configured to monitor a plurality of pressure values at the plurality of storage locations 720 in real time, and the controller 1 calculates the variation of the plurality of pressure values according to the plurality of pressure values monitored during the first preset time. For example, the first preset time is in a range of 3s to 10s, for example, the first preset time is 3s, 5s or 10s.

In step 23, the controller 1 determines whether the variation of any one of the pressure values within the first preset time is greater than a preset pressure variation threshold, if yes, step 24 is executed, and if not, step 21 is executed again.

In step 24, the controller 1 determines that there is a new electronic tag 600 in the storage location 720 corresponding to the any one of the pressure values.

In some embodiments, the refrigerator 1000 includes one or more electronic tags 600, and the electronic tag 600 newly added in the storage location 720 corresponding to any one pressure value may be the electronic tag 600 detached from the food to be detected, or may be other electronic tags 600, which is not limited in this disclosure.

It will be appreciated that when the electronic tag 600 is not placed in one storage location 720, the pressure value detected by the pressure sensor 730 corresponding to that storage location 720 is small, for example, the pressure value detected by the pressure sensor 730 is 0N. When the pressure value detected by the pressure sensor 730 increases, for example, from 0N to any value greater than the pressure change threshold, and remains unchanged for a first preset time, the controller 1 may determine that there is a new electronic tag 600 in the storage location 720 (i.e., the electronic tag 600 is placed in the storage location 720).

In summary, the controller 1 can monitor the pressure values at the storage locations 720 through the pressure sensors 730, and determine whether the electronic tag 600 is placed in the storage locations 720 according to the variation of the pressure values, which is beneficial to improving the convenience of using the tag by the user.

In some embodiments, the controller 1 is further configured to perform steps 31 to 35.

In step 31, when the controller 1 determines that the electronic tag 600 is newly added in any one of the storage locations 720, the controller 1 obtains the information stored in the electronic tag 600 through the second antenna 710 to determine whether the information stored in the electronic tag 600 includes any odor detection index of any food material, if yes, step 32 is executed, and if no, step 35 is executed.

It is understood that the newly added electronic tag 600 may be an electronic tag 600 that has been used by the user. For example, when a user wants to monitor a certain food (such as a first food), entering an odor detection index corresponding to the first food into the electronic tag 600, and binding the electronic tag 600 with the first food; when the user needs to eat the first food material, the electronic tag 600 is detached from the first food material and placed in any one of the storage positions 720 in the first tag box 700, and in this case, the odor detection index of the first food material type is stored in the electronic tag 600.

In step 32, the controller 1 acquires the odor detection index of the food material category stored in the newly added electronic tag 600 to determine whether the food material category matches the food material category corresponding to any one of the storage locations 720, if yes, step 33 is executed, and if no, step 34 is executed.

In step 33, the controller 1 does not process the newly added electronic tag 600.

It can be understood that, the plurality of storage locations 720 correspond to odor detection indexes corresponding to a plurality of food material types, and when the food material types stored in the electronic tag 600 match the food material types corresponding to the storage locations 720, the controller 1 does not need to process the electronic tag 600.

In step 34, the controller 1 deletes the odor detection index stored in the electronic tag 600 through the second antenna 710, and writes the odor detection index of the food material type corresponding to any one of the storage locations 720 into the electronic tag 600.

It can be appreciated that when the type of food material stored in the electronic tag 600 is a first type of food material and the type of food material corresponding to the storage location 720 stored in the electronic tag 600 is a second type of food material, the odor detection index of the first type of food material stored in the electronic tag 600 needs to be deleted and written into the odor detection index of the second type of food material corresponding to the storage location 720, so that when a user needs to manage the second food material, the electronic tag 600 can be directly taken out from the storage location 720 and the electronic tag 600 and the second food material are bound, thereby being beneficial to improving the flexibility of use of the electronic tag 600.

In step 35, the controller 1 writes the odor detection index of the food material type corresponding to any one of the storage locations 720 into the electronic tag 600 via the second antenna 710.

In summary, the user may identify and edit the electronic tag 600 through the controller 1 and the second antenna 710, and bind the electronic tag 600 with the food to be detected to monitor the food, so that the odor detection index in the electronic tag 600 may be changed along with the change of the food to be bound, which is beneficial to improving the flexibility of use of the electronic tag 600.

In some embodiments, as shown in fig. 9, the electronic tag 600 further includes a power supply unit 620, and the power supply unit 620 includes a rechargeable battery 621. The first tag cassette 700 further includes a plurality of charging devices 740, where the plurality of charging devices 740 correspond to the plurality of storage locations 720 and are disposed in the plurality of storage locations 720, respectively. The charging device 740 is configured to charge the electronic tag 600 in the storage location 720 corresponding thereto. For example, the charging device 740 may perform wired charging or wireless charging on the electronic tag 600.

In some embodiments, the controller 1 is further configured to perform steps 41 to 45.

In step 41, when an electronic tag 600 is newly added in any one of the storage locations 720, the controller 1 acquires the electric quantity value of the electronic tag 600.

In step 42, the controller 1 determines whether the electric quantity value of the electronic tag 600 is smaller than a preset electric quantity threshold, if yes, step 43 is executed, and if not, step 41 is executed again.

In step 43, the controller 1 controls the charging device 740 corresponding to any one of the storage locations 720 to be started so as to charge the rechargeable battery 621 of the electronic tag 600.

In step 44, the controller 1 determines whether the electric quantity value of the rechargeable battery 621 of the electronic tag 600 reaches the full-charge threshold, if yes, step 45 is executed, and if not, step 44 is repeatedly executed.

In step 45, the controller 1 controls the charging device 740 to be turned off to stop charging the rechargeable battery 621.

For example, the full power threshold is any value between 95% and 100%, for example, the full power threshold is 95%, 98%, or 100%. In some embodiments, when the controller 1 determines that the electric quantity value of the rechargeable battery 621 of the electronic tag 600 reaches 100%, the charging device 740 is controlled to be turned off to stop charging the rechargeable battery 621.

In some embodiments, after step 14, the controller 1 is further configured to perform steps 15 to 16.

In step 15, after sending the prompt message for the second preset time, the controller 1 determines whether the first antenna 500 detects the electronic tag 600 satisfying the food material odor condition, if yes, step 16 is executed, and if no, the control logic is ended.

In step 16, the controller 1 decreases the target temperature of the storage compartment where the electronic tag 600 is located within the preset temperature adjustment range.

For example, the second preset time may be any value between 30min and 90min, for example, the second preset time is 30min, 60min, or 90min.

It can be understood that if the controller 1 can still detect the electronic tag 600 satisfying the food odor condition when sending the prompt message for 60min, it can be determined that the food to be processed bound by the electronic tag 600 is still stored in the storage compartment. At this time, the controller 1 reduces the temperature of the storage compartment within a preset temperature adjustment range. For example, the temperature adjustment range is 2 ℃, that is, the controller 1 may decrease the target temperature of the storage compartment by 2 ℃ to reduce the deterioration rate of the food material.

In some embodiments, the controller 1 is further configured to: after the target temperature of the storage compartment where the electronic tag 600 is located is reduced within the preset temperature adjustment range for a third preset time, the temperature of the storage compartment is restored to the original target temperature, so that the storage compartment can be prevented from being in a low-temperature state for a long time, and the energy consumption of the refrigerator 1000 can be reduced. For example, the third preset time is 24h.

In some embodiments, the controller 1 is further configured to: in a third preset time for reducing the target temperature of the storage compartment where the electronic tag 600 is located, judging whether the first antenna 500 detects the electronic tag 600 meeting the food odor condition, if so, maintaining the target temperature of the storage compartment until the third preset time, and if not, recovering the temperature of the storage compartment to be the original target temperature.

In some embodiments, the controller 1 comprises a timer 2, the timer 2 being configured to time the first preset time, the second preset time and the third preset time.

In some embodiments, as shown in fig. 10 and 11, the refrigerator 1000 further includes a second tag cassette 800 (e.g., an RFID tag cassette). The second tag cassette 800 includes a cassette body 810, a cassette cover 820, at least one spacer 830, a plurality of detection devices 840, and a reader 850 (e.g., RFID read/write module).

One side (e.g., the upper side) of the case 810 is opened to define an opening 811, and a cover 820 is provided on the case 810 to close the opening 811.

At least one partition 830 is disposed in the case 810 to define a plurality of receiving grooves 831. Each receiving recess 831 corresponds to one type of food material and is configured to receive an electronic tag 600 (e.g., an RFID tag).

The plurality of detecting devices 840 correspond to the plurality of receiving grooves 831, and are respectively disposed in the plurality of receiving grooves 831. The detecting means 840 is configured to detect one or more indexes in the receiving recess 831 corresponding thereto to determine whether there is a newly added electronic tag 600 in the receiving recess 831 (i.e., to determine whether there is an electronic tag 600 placed in the receiving recess 831).

In some embodiments, the detection device 840 includes a pressure sensor (i.e., a weight sensor). When the pressure sensor detects that the pressure value in the accommodating tank 831 increases, the detecting device 840 may determine that the accommodating tank 831 has a new electronic tag 600 added; or when the pressure sensor detects a decrease in the pressure value in the receiving recess 831, the detection device 840 may determine that the electronic tag 600 in the receiving recess 831 is taken out.

In some embodiments, detection device 840 includes a light sensor. When the light sensor detects that the brightness value in the accommodating groove 831 increases, the detecting device 840 may determine that the accommodating groove 831 has a new electronic tag 600; or when the light sensor detects a decrease in the brightness value in the receiving tank 831, the detection device 840 may determine that the electronic tag 600 in the receiving tank 831 is taken out.

The reader/writer 850 is disposed in the case 810, and is configured to send a signal (e.g., an RFID signal) to the electronic tag 600 to write food information corresponding to any one of the receiving grooves 831 to the electronic tag 600 when there is a newly added electronic tag 600 in the any one of the receiving grooves 831. Thus, when a user needs to manage a certain food (i.e., bind a certain food with the electronic tag 600 and then put it into the refrigerator 1000), the electronic tag 600 corresponding to the food can be directly taken out from the second tag box 800, and the electronic tag 600 is bound with the food, thereby being beneficial to improving the convenience of using the electronic tag 600.

Illustratively, the reader/writer 850 is vertically mounted in the middle of the cartridge 810, between the plurality of receiving slots 831. For example, the plurality of receiving grooves 831 includes a first row of receiving grooves and a second row of receiving grooves, and the reader/writer 850 is located between the first row of receiving grooves and the second row of receiving grooves. For example, the at least one spacer 830 includes a first spacer 832, the first spacer 832 separating a first row of receiving slots (i.e., a first portion of receiving slots) from a second row of receiving slots (i.e., a second portion of receiving slots), and the reader 850 is disposed on the first spacer 832.

In some embodiments, the second cassette 800 further comprises a communication device (e.g., a communication module) comprising at least one of a wireless fidelity (Wi-Fi) component and a bluetooth component. The second tag box 800 is communicatively connected to the client 103 through the communication device, and the user may send an instruction signal to the second tag box 800 through the client 103, in which case the communication device is configured to modify the food material information corresponding to any one of the receiving slots 831 in response to the instruction signal sent by the user.

For example, when a user needs to put pork and shrimp in the refrigerator 1000, the electronic tags 600 corresponding to the pork and shrimp, respectively, may be taken out from the second tag box 800, then the electronic tags 600 corresponding to the pork are bound to the pork, the electronic tags 600 corresponding to the shrimp are bound to the shrimp, and then the pork and the shrimp are put in the refrigerator 1000 to be stored.

In addition, when a user needs to put a plurality of parts of pork into the refrigerator 1000 and the number of the electronic tags 600 corresponding to the pork in the second tag box 800 is insufficient, the electronic tags 600 corresponding to other food materials (such as shrimps and the like) in the accommodating grooves 831 may be inserted into the accommodating grooves 831 corresponding to the pork, food material information corresponding to the pork is written in, and then the electronic tags 600 after the information is written in are bound with the pork. In this way, the user does not need to manually edit the food information stored in the electronic tag 600, so that the steps of food management can be simplified, and the time for food management can be saved.

In some embodiments, referring to fig. 11, the depth of the receiving recess 831 is less than the height of the electronic tag 600 (i.e., the length of the electronic tag 600), such that when the electronic tag 600 is disposed in the receiving recess 831, a portion of the electronic tag 600 is located outside of the receiving recess 831 to facilitate the user's access to the electronic tag 600.

In some embodiments, as shown in fig. 10 and 11, the cover 820 includes a top wall 821, and a distance between the top wall 821 and a bottom of the receiving recess 831 is greater than a height of the electronic tag 600, so that the cover 820 can cover the portion of the electronic tag 600 to protect the electronic tag 600 when the cover 820 closes the opening 811.

In some embodiments, as shown in fig. 10 and 11, the lid 820 further includes a first display 822. The first display screen 822 is disposed on a side surface of the top wall 821 near the cartridge 810 and configured to display food material information corresponding to the plurality of receiving grooves 831, thereby facilitating a user to refer to the food material information corresponding to each receiving groove 831.

Illustratively, the first display 822 is further configured to: when the cover 820 is opened, food material information corresponding to the plurality of receiving grooves 831 is displayed, and when the cover 820 is closed, it is not lighted, so that electricity can be saved, and power consumption of the second tag box 800 can be reduced.

In some embodiments, as shown in fig. 9, the electronic tag 600 further includes a second display screen 630, the second display screen 630 configured to display food material information stored in the electronic tag 600. In this way, when the user takes the electronic tag 600 out of the receiving slot 831, the food information stored in the electronic tag 600 can still be referred to through the second display screen 630.

In some embodiments, the cover 820 is hinged to the case 810 by a hinge, or the cover 820 includes a first connection portion, the case 810 includes a second connection portion, and the cover 820 is detachably connected to the case 810 by the first connection portion.

In step S6, the controller 1 decreases the target temperature of the storage compartment where the electronic tag 600 is located within the preset temperature adjustment range.

In some embodiments, the method for monitoring food materials in the refrigerator further includes that the controller 1 restores the temperature of the storage compartment to the original target temperature after reducing the target temperature of the storage compartment where the electronic tag 600 is located within the preset temperature adjustment range for a third preset time, so that the storage compartment can be prevented from being in a low temperature state for a long time, and the energy consumption of the refrigerator 1000 is reduced. For example, the third preset time is 24h.

In some embodiments, the method for monitoring food materials in a refrigerator further includes that the controller 1 determines whether the first antenna 500 detects the electronic tag 600 satisfying the food material odor condition within a third preset time for reducing the target temperature of the storage compartment where the electronic tag 600 is located, if yes, the target temperature of the storage compartment is maintained until the third preset time, and if not, the temperature of the storage compartment is restored to the original target temperature.

The first cassette 700 includes a second antenna 710, a plurality of storage locations 720, and a plurality of pressure sensors 730 disposed on the plurality of storage locations 720.

In some embodiments, the first tag cassette 700 further includes a housing 701, the housing 701 being constructed of a shielding material (e.g., metal, etc.). In this way, when the first tag box 700 is placed in the refrigerator 1000, the second antenna 710 may sense the electronic tag 600 placed in the storage compartment, and the first antenna 500 may not sense the electronic tag 600 in the first tag box 700.

As shown in fig. 14, the food material monitoring method of the refrigerator further includes steps S11 to S13.

In step S11, the controller 1 receives a plurality of pressure values on a plurality of storage locations 720 detected by a plurality of pressure sensors 730.

In some embodiments, as shown in fig. 15, after step S13, the food material monitoring method of the refrigerator further includes steps S14 to S18.

In step S14, when the controller 1 determines that the electronic tag 600 is newly added in any one of the storage locations 720 (i.e., the storage location 720 corresponding to any one of the pressure values), the controller 1 obtains the information stored in the newly added electronic tag 600 through the second antenna 710 to determine whether the information stored in the electronic tag 600 includes the odor detection index of any one of the food material types, if yes, step S15 is executed, and if no, step S18 is executed.

In step S15, the controller 1 obtains the odor detection index of any one of the food material types stored in the newly added electronic tag 600 through the second antenna 710 to determine whether the any one of the food material types matches the food material type corresponding to the any one of the storage locations 720, if yes, step S16 is executed, and if no, step S17 is executed.

In step S16, the controller 1 does not process the newly added electronic tag 600.

In step S17, the controller 1 deletes the odor detection index stored in the electronic tag 600 through the second antenna 710, and writes the odor detection index of the food material type corresponding to any one of the storage locations 720 into the electronic tag 600.

In step S18, the controller 1 writes the odor detection index of the food material type corresponding to any one of the storage locations 720 to the newly added electronic tag 600 via the second antenna 710.

As shown in fig. 16, after step S13, the food material monitoring method of the refrigerator further includes steps S21 to S25.

In step S21, when the electronic tag 600 is newly added to any one of the storage locations 720, the controller 1 acquires the electric quantity value of the electronic tag 600.

In step S22, the controller 1 determines whether the electric quantity value of the electronic tag 600 is smaller than a preset electric quantity threshold, if yes, step S23 is executed, and if no, step S21 is executed again.

In step S23, the controller 1 controls the charging device 740 corresponding to any one of the storage locations 720 to be started so as to charge the rechargeable battery 621 of the electronic tag 600.

In step S24, the controller 1 determines whether the electric quantity value of the rechargeable battery 621 of the electronic tag 600 reaches the full-charge threshold, if yes, step S25 is executed, and if no, step S24 is repeatedly executed.

In step S25, the controller 1 controls the charging device 740 to be turned off to stop charging the rechargeable battery 621.
