Background

In practical use, a user usually stores a large amount of food in a storage compartment (a refrigerating compartment or a freezing compartment, etc.), the food has respective shelf lives, and when the storage time of the food in the storage compartment exceeds the shelf life, the food cannot be eaten. In order to help users manage the foods, in the existing technical scheme of marking and managing the foods through tags, the tags are accommodated in a tag box, an identification module is arranged in the tag box to judge whether the tags are taken out or put in the tag box, and the identification module does not generally have a reading and writing function. In some technical solutions in which the tag may be defined by the user, another read/write module with a read/write function is usually disposed outside the tag box to edit the tag. In such a space range of the refrigerator, the electromagnetic signals emitted by the two modules may have an overlapped portion, and the tag only responds to the electromagnetic signal that arrives first in the overlapped space, which easily causes that the read-write module with the read-write function cannot receive the response information of the tag, and such multiple read-write modules operate simultaneously and interfere with each other, causing the read-write delay or failure of the tag information.

In order to avoid the problem that the electromagnetic signals emitted by the two modules are overlapped, the label box made of shielding materials is also commonly adopted in the prior art, so that the reading and writing module arranged outside the label box can not detect the label placed in the label box, however, the label box made of shielding materials is expensive in manufacturing cost and has higher requirements on the manufacturing process, and the cost of the whole refrigerator is higher.

The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.

Referring to fig. 1, fig. 1 is a perspective view of a refrigerator according to an embodiment of the present application. The refrigerator of the embodiment is approximately in a cuboid shape, and comprises a refrigerator body for limiting a storage space and a plurality of door bodies arranged at an opening of the refrigerator body, wherein each door body comprises a door body shell positioned at the outer side of the refrigerator body, a door body liner positioned at the inner side of the refrigerator body, an upper end cover, a lower end cover and a heat insulation layer positioned among the door body shell, the door body liner, the upper end cover and the lower end cover; typically, the thermal insulation layer is filled with a foam material. The cabinet is provided with a chamber including a component storage chamber for storing components in the refrigerator, such as a compressor, etc., and a storage space for storing food, etc. The storage space may be divided into a plurality of storage chambers, and the storage chambers may be configured as a refrigerating chamber, a freezing chamber, and a temperature-changing chamber according to use. One or more door bodies are associated with each storage compartment, for example, in fig. 1, the storage compartment in the upper portion is provided with a double door body. The door body can be pivotally arranged at the opening of the box body and can be opened in a drawer mode so as to achieve drawer type storage.

Referring to fig. 2, fig. 2 is a schematic structural diagram of a refrigeration system in a refrigerator according to an embodiment of the present invention, where the refrigeration system includes a compressor 1, a condenser 2, a condensation preventing pipe 3, a dry filter 4, a capillary tube 5, an evaporator 6, and a gas-liquid separator 7. The working process of the refrigeration system comprises a compression process, a condensation process, a throttling process and an evaporation process.

Wherein, the compression process is as follows: the power cord of the refrigerator is plugged, when the contact of the temperature controller is connected, the compressor 1 starts to work, the low-temperature and low-pressure refrigerant is sucked by the compressor 1, and is compressed into high-temperature and high-pressure superheated gas in the cylinder of the compressor 1 and then is discharged into the condenser 2; the condensation process is as follows: the high-temperature and high-pressure refrigerant gas is radiated by the condenser 2, the temperature is continuously reduced, the refrigerant gas is gradually cooled into normal-temperature and high-pressure saturated vapor and further cooled into 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 refrigerant saturated liquid flows into the capillary tube 5 after moisture and impurities are filtered by the drying filter 4, throttling and pressure reduction are carried out through the capillary tube, and the refrigerant is changed into normal-temperature low-pressure wet vapor; the evaporation process is as follows: the normal temperature and low pressure wet steam starts to absorb heat for vaporization in the evaporator 6, which not only reduces the temperature of the evaporator and the surrounding, but also changes the refrigerant into low temperature and low pressure gas, the refrigerant from the evaporator 6 returns to the compressor 1 again after passing through the gas-liquid separator 7, the above processes are repeated, the heat in the refrigerator is transferred to the air outside the refrigerator, and the purpose of refrigeration is realized.

Referring to fig. 3, fig. 3 is a schematic position diagram of a fan 8 in the refrigerator according to the embodiment of the present invention, where the fan 8 makes air continuously enter fins of the evaporator 6 for heat exchange, and sends air that has cooled after heat release of the evaporator 6 to the refrigerating chamber and the freezing chamber through an air duct, so that air in the storage chamber continuously circulates and flows to achieve the purpose of reducing temperature.

Referring to fig. 4, fig. 4 is a schematic structural diagram of a food material management system provided in the refrigerator according to an embodiment of the present invention, where the food material management system is disposed in the refrigerator and includes a tag box 10, a first read/write module 11, and a second read/write module 12; the first read-write module 11 is disposed in the tag box 10 and operates in a multi-tag read-write mode, and at this time, the first read-write module 11 can read tag information of all electronic tags in the tag box 10; the second read/write module 12 is disposed outside the tag box 10, and works in a single tag read/write mode, and at this time, the second read/write module 12 only reads tag information of an electronic tag closest to (first detected by) the second read/write module 12.

For example, referring to fig. 4, an electronic tag 20 is placed in the tag box 10, a display screen for displaying food material information of the electronic tag 20 is arranged on the electronic tag 20, the tag information includes an identification code of the electronic tag and food material information corresponding to the identification code, the identification code is used as a unique identification code of the electronic tag, and the food material information can be changed according to a food material editing operation of a user. Further, the electronic tag may also be placed back into the tag box 10 after deleting the food material information corresponding to the electronic tag (for example, after the user places the electronic tag back into the tag box 10, the user interacts with the controller 13 through the voice module to delete the food material information in the electronic tag), and then the food material information corresponding to the electronic tag is empty.

It should be noted that, the first read/write module 11 and the second read/write module 12 are separated by a predetermined distance, and the predetermined distance should satisfy: it is ensured that the second read/write module 12 does not detect the tag information of any electronic tag placed in the tag box 10 during operation. In addition, the first read-write module 11 is disposed in the middle of the label box 10, and the detection range of the first read-write module needs to ensure that the label information of all electronic labels disposed in the label box 10 can be read; the second reading/writing module 12 may be disposed on a door of the refrigerator or near the tag box 10 (for a user to perform an editing operation after taking out the refrigerator), and a detection range of the second reading/writing module 12 may be adjusted by the user or preset before leaving the refrigerator, but cannot satisfy the condition that "the tag information of any electronic tag in the tag box 10 can be detected".

It should be noted that the electronic tag according to the embodiment of the present invention is an RFID tag or an NFC tag, when the electronic tag configured for the refrigerator is an RFID tag, the read-write module is a read-write module corresponding to the RFID tag, and when the electronic tag configured for the refrigerator is an NFC tag, the read-write module is a read-write module 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 a Radio Frequency mode so as to achieve the purposes of identifying a target and exchanging data, and combines a data access technology with a database system through Radio wave non-contact quick information exchange and storage technology and wireless communication so as to realize non-contact bidirectional communication, thereby achieving the purpose of Identification. 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 initiating device (master device), provides a radio frequency field (RF-field) during the whole communication process, and it can choose one of the transmission speeds of 106kbps, 212kbps or 424kbps to transmit data to another device, called the target device (slave device), and does not need to generate a radio frequency field, but uses load modulation (load modulation) technology to transmit data back to the initiating device at the same speed, and in the active mode, both the initiating device and the target device generate their own radio frequency field for communication.

Referring to fig. 5, fig. 5 is a schematic connection relationship diagram of a controller 13 according to an embodiment of the present invention, where the controller 13 is respectively connected to the first read-write module 11, the second read-write module 12, and the voice module 14, the first read-write module 11 and the second read-write module 12 are respectively provided with an antenna coil and a chip (such as an NFC chip or an RFID chip), and the voice module 14 is arranged on a box of the refrigerator and configured to receive a voice instruction of a user.

Specifically, the controller 13 is configured to: when detecting that the food material management system is powered on and initialized, controlling the first read-write module 11 to start and controlling the second read-write module 12 to stop; acquiring monitoring data of the first read-write module 11; when it is detected that the electronic tag is taken out from the tag box 10, the first reading/writing module 11 is controlled to stop, and the second reading/writing module 12 is started, so that the second reading/writing module 12 is utilized to perform food material editing operation on the taken-out electronic tag.

Exemplarily, referring to fig. 6, fig. 6 is a first work flow chart of the controller 13 in the refrigerator according to the embodiment of the present invention, where the controller 13 is configured to execute steps S11 to S15:

s11, judging whether the food material management system is initialized or not, if so, entering a step S12, and if not, continuing to execute the step S11.

And S12, when detecting that the food material management system is electrified and initialized, controlling the first read-write module 11 to start, and controlling the second read-write module 12 to stop, and then entering the step S13.

And S13, acquiring monitoring data of the first read-write module 11, acquiring tag information of all electronic tags in the tag box 10 at this time, and then entering step S14.

S14, judging whether the electronic tag is taken out from the tag box 10 or not, if so, entering the step S15, and if not, repeatedly executing the step S14.

And S15, when detecting that the electronic tag is taken out from the tag box 10, controlling the first reading and writing module 11 to stop, and starting the second reading and writing module 12 to perform food material editing operation on the taken-out electronic tag by using the second reading and writing module 12.

For example, the first read/write module 11 disposed in the tag box 10 reads the tag information of the electronic tags in the tag box 10 at a certain interval (for example, 1 s), and can know which electronic tags are taken out or which electronic tags are newly added into the tag box 10 by comparing the tag data (for example, comparing the identification code) twice before and after comparison. When it is monitored that the electronic tag is taken out of the tag box 10, it indicates that the user needs to use the electronic tag at this time, and at this time, the food material binding operation needs to be performed, so that the first read-write module 11 is turned off, and the first read-write module 11 is prevented from affecting the read-write process of the second read-write module 12. The steps S11 to S15 are application scenarios when the food material management system is initialized, and in subsequent use, the first read-write module 11 and the second read-write module 12 are alternately started to operate, and one is closed while the other is closed, so as to avoid mutual influence.

Specifically, after the monitoring data of the first read-write module 11 is obtained, the controller 13 is further configured to: storing the tag information corresponding to all the electronic tags in the tag box 10 read by the first read-write module 11 into a preset un-stored food material database; the electronic tag is provided with a display screen for displaying food material information of the electronic tag, and the tag information comprises an identification code of the electronic tag and food material information corresponding to the identification code;

when detecting that the electronic tag is taken out from the tag box 10, the controller 13 is further configured to: and acquiring the food material information of the taken-out electronic tag from the non-stored food material database, and deleting the food material information of the taken-out electronic tag from the non-stored food material database.

For example, referring to fig. 7, fig. 7 is a second flowchart of the operation of the controller 13 in the refrigerator according to the embodiment of the present invention, in which after step S13 is executed, the controller 13 is further configured to execute step S131:

s131, storing the tag information corresponding to all the electronic tags in the tag box 10 read by the first read-write module 11 into a preset un-stored food database, and then entering step S14. Tag information of all electronic tags placed in the tag box 10 is stored in the non-stored food material database.

After step S14, the controller 13 is further configured to execute step S141:

s141, the food material information of the electronic tag is obtained from the unstored food material database, the food material information of the electronic tag is deleted from the unstored food material database, and then the step S15 is executed. When the electronic tag is detected to be taken out, the electronic tag is required to be bound with the food material, so that the corresponding tag information is required to be deleted from the non-stored food material database.

Specifically, after the second read/write module 12 is started, the controller 13 is further configured to: acquiring monitoring data of the second read-write module 12; if the second read-write module 12 reads the electronic tag taken out within a preset time period, starting a tag information editing mode; if the second reading and writing module 12 does not read the electronic tag taken out within a preset time period, the food material information of the electronic tag taken out is stored in the stored food material database.

Exemplarily, referring to fig. 8, fig. 8 is a third flowchart of the controller 13 in the refrigerator according to the embodiment of the present invention, and after step S15 is executed, the controller 13 is further configured to execute steps S16 to S19:

and S16, acquiring the monitoring data of the second read-write module 12, and then entering the step S17.

And S17, judging whether the second read-write module 12 reads the taken-out electronic tag within a preset time period, if so, entering a step S19, and otherwise, entering a step S18.

And S18, if the taken-out electronic tag is not read by the second reading and writing module 12 within a preset time period, storing the food material information of the taken-out electronic tag into the stored food material database.

And S19, if the second read-write module 12 reads the taken-out electronic tag within a preset time period, starting a tag information editing mode.

For example, if the second read/write module 12 does not read the taken out electronic tag within a preset time period, it indicates that the taken out electronic tag is not edited by the user and can be directly applied to the food materials to be bound, because the electronic tag is provided with the display screen, the user can directly see the food material information written by the electronic tag on the display screen, and if the electronic tag corresponds to the current food materials to be bound, the user can directly apply the electronic tag without performing the tag information editing mode. It can be understood that, for an electronic tag in which a user does not perform a tag information editing mode, when the food material information is stored in the stored food material database, the controller 13 may automatically change the storage date in the food material information (without manual operation), so as to facilitate automatic monitoring of the food material.

Specifically, the tag information editing mode includes: sending out voice prompt information; the voice prompt information is used for reminding a user whether to perform food material editing operation on the electronic tag taken out of the tag box 10; when a voice instruction which is replied by a user and does not need to be changed is received, storing the taken food material information of the electronic tag into the stored food material database; when a voice instruction which needs to be changed and is replied by a user is received, the voice editing instruction of the user is collected, corresponding food material information is written into the electronic tag according to the voice editing instruction, and the food material information of the electronic tag after being edited is stored into a preset stored food material database.

Exemplarily, referring to fig. 9, fig. 9 is a fourth operation flowchart of the controller 13 in the refrigerator according to the embodiment of the present invention, and the step S19 specifically includes steps S191 to S194:

s191, voice prompt information is sent out, and then the process goes to step S192 or step S193.

And S192, when a voice command which is replied by a user and does not need to be changed is received, storing the taken-out food material information of the electronic tag into the stored food material database.

And S193, acquiring the voice editing instruction of the user when the voice instruction which needs to be changed and is replied by the user is received, and then entering the step S194.

And S194, writing the corresponding food material information into the electronic tag according to the voice editing instruction, and storing the food material information of the edited electronic tag into a preset stored food material database.

For example, if the second reading/writing module 12 reads the electronic tag taken out within a preset time period (the user brings the electronic tag close to the second reading/writing module 12), it indicates that the user needs to edit/confirm the food material information recorded in the electronic tag at this time, and at this time, the tag information editing mode is started. The user may also start the tag information editing mode, and then does not change the tag information, which may be caused by false triggering, so that the user may feed back a voice instruction that does not need to be changed after receiving a voice prompt (for example, asking the user whether to change the food material information), and at this time, may directly store the taken out food material information of the electronic tag in the stored food material database. And when a voice instruction which is replied by the user and needs to be changed is received, editing the food material information according to the voice information fed back by the user, and storing the edited food material information of the electronic tag into a preset stored food material database.

Specifically, after the second read/write module 12 is activated, the controller 13 is further configured to: when detecting that the tag information written in the stored food material database corresponds to the tag information deleted in the non-stored food material database one to one, controlling the second read-write module 12 to stop, and starting the first read-write module 11.

Exemplarily, referring to fig. 10, fig. 10 is a fifth work flowchart of the controller 13 in the refrigerator according to the embodiment of the present invention, where the controller 13 is further configured to execute step S20:

and S20, when detecting that the tag information written in the stored food material database corresponds to the tag information deleted in the non-stored food material database in a one-to-one manner, controlling the second read-write module 12 to stop, and starting the first read-write module 11.

For example, when it is detected that the tag information written in the stored food material database corresponds to the tag information deleted from the non-stored food material database one to one, it indicates that the tags taken out from the tag box 10 by the user have been re-recorded into the stored food material database at this time, that is, the binding of the stored food material is completed, for example, it is detected that two electronic tags in the tag box 10 are taken out, at this time, the tag information stored in the non-stored food material database by the two electronic tags is deleted, because the controller 13 acquires the tag information of the two electronic tags together, the tag information of the two electronic tags is written into the stored food material database, it indicates that the food materials corresponding to the two electronic tags are stored in the refrigerator, at this time, it is necessary to control the second reading and writing module 12 to stop, start the first reading and writing module 11, and then continue to execute the above steps S13 to S20.

Referring to fig. 11, fig. 11 is a schematic diagram of information interaction between a refrigerator and a client according to an embodiment of the present invention, where the refrigerator 100 establishes a data connection with the client 200 through a router 300 or a cloud server 400.

Referring to fig. 12, fig. 12 is a flowchart of a food material tag management method for a refrigerator according to an embodiment of the present invention, where the food material tag management method for the refrigerator according to the embodiment of the present invention is implemented by a controller in the refrigerator, the refrigerator includes a food material management system, and the food material management system is disposed in the refrigerator and includes a tag box, a first read/write module, and a second read/write module; the first read-write module is arranged in the label box and works in a multi-label read-write mode, and the second read-write module is arranged outside the label box and works in a single-label read-write mode; then, the food material tag management method includes:

s1, when detecting that the food material management system is electrified and initialized, controlling a first read-write module to start and controlling a second read-write module to stop;

s2, acquiring monitoring data of the first read-write module;

and S3, when the electronic tag is detected to be taken out of the tag box, controlling the first reading and writing module to stop, and starting the second reading and writing module so as to utilize the second reading and writing module to carry out food material editing operation on the taken-out electronic tag.

For example, the first read/write module disposed in the label box reads the label information of the electronic labels in the label box at intervals (for example, 1 s), and can know which electronic labels are taken out or which electronic labels are newly added into the label box by comparing the label data (for example, comparing the identification code) of the first read/write module and the label data of the second read/write module before and after the first read/write module. When the electronic tag is monitored to be taken out of the tag box, the fact that the electronic tag is needed by a user at the moment is indicated, and food material binding operation is needed at the moment, so that the first reading-writing module is closed, and the first reading-writing module is prevented from influencing the reading-writing process of the second reading-writing module.

Specifically, after the monitoring data of the first read-write module is obtained, the method further includes:

storing the label information corresponding to all the electronic labels in the label box read and written by the first read-write module into a preset food material non-storage database; the electronic tag is provided with a display screen for displaying food material information of the electronic tag, and the tag information comprises an identification code of the electronic tag and food material information corresponding to the identification code; when detecting that the electronic tag is taken out of the tag box, the controller is further used for: and acquiring the food material information of the taken-out electronic tag from the unstored food material database, and deleting the food material information of the taken-out electronic tag from the unstored food material database.

For example, the tag information of all the electronic tags placed in the tag box is stored in the non-stored food material database. When the electronic tag is detected to be taken out, the electronic tag is required to be bound with the food material, so that the corresponding tag information is required to be deleted from the non-stored food material database.

Specifically, after the second read/write module is started, the method further includes:

acquiring monitoring data of the second read-write module; if the second read-write module reads the taken electronic tag within a preset time period, starting a tag information editing mode; and if the second reading and writing module does not read the taken-out electronic tag within a preset time period, storing the food material information of the taken-out electronic tag into the stored food material database.

For example, if the second read-write module does not read the taken out electronic tag within a preset time period, it indicates that the taken out electronic tag can be directly applied to the food materials to be bound without being edited by the user, and because the electronic tag is provided with the display screen, the user can directly see the food material information written by the electronic tag on the display screen, and if the electronic tag corresponds to the current food materials to be bound, the user can directly apply the electronic tag without performing a tag information editing mode. It can be understood that, for an electronic tag in which a user does not perform a tag information editing mode, when the food material information is stored in the stored food material database, the controller can automatically change the storage date in the food material information (without manual operation), so that the food material can be conveniently and automatically monitored.

Specifically, the tag information editing mode includes:

sending out voice prompt information; the voice prompt information is used for reminding a user whether to perform food material editing operation on the electronic tag taken out of the tag box; when a voice instruction which is replied by a user and does not need to be changed is received, storing the taken food material information of the electronic tag into the stored food material database; when a voice instruction which is replied by a user and needs to be changed is received, the voice editing instruction of the user is collected, the corresponding food material information is written into the electronic tag according to the voice editing instruction, and the food material information of the edited electronic tag is stored into a preset stored food material database.

For example, if the second read/write module reads the electronic tag taken out within a preset time period (the user brings the electronic tag close to the second read/write module), it indicates that the user needs to edit/confirm the food material information recorded in the first electronic tag, and at this time, the tag information editing mode is started. The user may also start the tag information editing mode, and then does not change the tag information, which may be caused by false triggering, so that the user may feed back a voice instruction that does not need to be changed after receiving a voice prompt (for example, asking the user whether to change the food material information), and at this time, may directly store the food material information of the electronic tag that is taken out into the stored food material database. And when a voice instruction which is replied by the user and needs to be changed is received, editing the food material information according to the voice information fed back by the user, and storing the edited food material information of the electronic tag into a preset stored food material database.

For example, when it is detected that tag information written in the stored food material database corresponds to tag information deleted from the non-stored food material database in a one-to-one manner, it indicates that tags taken out from the tag box by a user have been re-recorded into the stored food material database, that is, the binding of the stored food material is completed, for example, it is detected that two electronic tags in the tag box are taken out, and at this time, tag information stored in the non-stored food material database by the two electronic tags is deleted.

It should be noted that, in the food material tag management method for the refrigerator according to the embodiment of the present invention, reference may be made to the workflow of the controller in the refrigerator according to the above embodiment, and details are not repeated herein.
