Description

Refrigerator and food label management method thereof

Technical Field

The invention relates to the technical field of refrigerators, in particular to a refrigerator and a food label management method thereof.

Background

Refrigerators are a commonly used household appliance in daily life, and in actual 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 lives, the food cannot be eaten. In order to assist users in managing these foods, in the conventional technical scheme of labeling foods and managing them by using tags, tags are accommodated in a tag box, and an identification module is built in the tag box to judge whether the tags are taken out or put in, and the identification module generally has no read-write function. In some technical schemes in which the tag can define the associated food information by the user, another read-write module with read-write function is usually arranged outside the tag box to edit the tag. In such a space range, electromagnetic signals emitted by the two modules have overlapping parts, and when the label is in the overlapping space, the label only responds to the electromagnetic signals which arrive first, so that the read-write module with the read-write function can not receive the response information of the label easily, and a plurality of read-write modules work simultaneously and mutually interfere, thereby causing delay or failure of read-write of the label information.

In order to avoid the problem that electromagnetic signals emitted by the two modules are overlapped, a tag box made of shielding materials is also commonly adopted in the prior art, so that a read-write module arranged outside the tag box cannot detect tags stored in the tag box, however, the tag box made of the shielding materials is expensive in manufacturing cost and high in manufacturing process requirement, and the cost of the whole refrigerator is high.

The specific meaning of the above terms in the present application will be understood in specific cases by those of ordinary skill in the art.

Referring to fig. 1, fig. 1 is a perspective view of one embodiment of a refrigerator according to the present application. The refrigerator of the embodiment is approximately cuboid in shape and comprises a refrigerator body and a plurality of door bodies, wherein the refrigerator body is used for limiting a storage space, the door bodies are arranged at the opening of the refrigerator body, and comprise 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 insulating layer is filled with a foaming material. The cabinet is provided with a chamber including a component storage chamber for storing components in the refrigerator, such as a compressor, and a storage space for storing food and the like. The storage space may be partitioned into a plurality of storage compartments, which may be configured as a refrigerating compartment, a freezing compartment, and a temperature changing compartment according to the use. Each storage compartment corresponds to one or more doors, for example, in fig. 1, the upper storage compartment is provided with a double door. The door body can be pivoted at the opening of the box body and can also be opened in a drawer mode, so that drawer type storage is realized.

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

The compression process comprises the following steps: when the power line of the refrigerator is inserted and 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, compressed into high-temperature and high-pressure overheat gas in the cylinder of the compressor 1 and then discharged to the condenser 2; the condensation process is as follows: the high-temperature and high-pressure refrigerant gas radiates heat through the condenser 2, the temperature is continuously reduced, the refrigerant gas is gradually cooled into normal-temperature and high-pressure saturated steam, the saturated steam is further cooled into saturated liquid, the temperature is not reduced any more, the temperature at the moment is called as condensing temperature, and the pressure of the refrigerant in the whole condensing process is almost unchanged; the throttling process is as follows: the condensed refrigerant saturated liquid is filtered by a dry filter 4 to remove moisture and impurities, and then flows into a capillary tube 5, throttling and depressurization are carried out through the capillary tube, and the refrigerant is changed into normal-temperature and low-pressure wet vapor; the evaporation process is as follows: the wet vapor with normal temperature and low pressure starts to absorb heat in the evaporator 6 for vaporization, so that the temperature of the evaporator and the surrounding temperature are reduced, the refrigerant is changed into low-temperature and low-pressure gas, the refrigerant coming out of the evaporator 6 returns to the compressor 1 again after passing through the gas-liquid separator 7, the process is repeated, and the heat in the refrigerator is transferred into the air outside the refrigerator, so that the purpose of refrigeration is realized.

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

Referring to fig. 4, fig. 4 is a schematic structural diagram of a food material management system 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 works 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 operates in a single tag read-write mode, where the second read-write module 12 only reads tag information of an electronic tag nearest to (detected first by) the second read-write module 12.

For example, referring to fig. 4, an electronic tag 20 is disposed in the tag box 10, a display screen for displaying food material information of the electronic tag 20 is disposed on the electronic tag 20, the tag information includes an identification code of the electronic tag and corresponding food material information thereof, the identification code is not modifiable as a unique identification code of the electronic tag, and the food material information is modifiable according to a food material editing operation of a user. Further, the electronic tag may be replaced in the tag box 10 after deleting the corresponding food information (for example, after the user replaces the electronic tag with the tag box 10, the user interacts with the controller 13 through the voice module to delete the food information in the electronic tag), so that the food information corresponding to the electronic tag is empty.

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

It should be noted that, in the embodiment of the present invention, the electronic tag is an RFID tag or an NFC tag, when the electronic tag configured in 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 in the refrigerator is an NFC tag, the read-write module is a read-write module corresponding to the NFC tag. The RFID tag adopts a radio frequency identification technology (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, thereby achieving the purpose of identification target and data exchange, and the radio frequency identification technology combines a data access technology through radio wave non-contact rapid information exchange and storage technology, and then is connected with a database system to realize non-contact bidirectional communication, thereby achieving the purpose of identification, being used for data exchange and being connected in series with a very complex system. The NCF tag adopts the technical principle of near field communication, and can exchange data through an active mode and a passive mode. In the passive mode, the device that initiates near field communication, also called the initiating device (master device), provides a radio frequency field (RF-field) throughout the communication, which may select one of transmission speeds 106kbps, 212kbps or 424kbps, sends data to another device, called the target device (slave device), and uses load modulation (load modulation) techniques to return data to the initiating device at the same speed, whereas in the active mode both the initiating device and the target device generate their own radio frequency fields for communication.

Referring to fig. 5, fig. 5 is a schematic diagram of a connection relationship between a controller 13 provided in an embodiment of the present invention, the controller 13 is respectively connected to the first read-write module 11, the second read-write module 12 and the voice module 14, antenna coils and chips (such as NFC chips or RFID chips) are respectively disposed in the first read-write module 11 and the second read-write module 12, and the voice module 14 is disposed on a box body of the refrigerator and is configured to receive a voice command of a user.

Specifically, the controller 13 is configured to: when the power-on initialization of the food management system is detected, the first read-write module 11 is controlled to be started, and the second read-write module 12 is controlled to be stopped; acquiring monitoring data of the first read-write module 11; when it is detected that the electronic tag in the tag box 10 is taken out, the first read-write module 11 is controlled to stop, and the second read-write module 12 is started, so that the second read-write module 12 is utilized to edit the food materials of the taken out electronic tag.

Referring to fig. 6, fig. 6 is a first operation flowchart of a controller 13 in a refrigerator according to an embodiment of the present invention, where the controller 13 is configured to perform steps S11 to S15:

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

And S12, when the power-on initialization of the food management system is detected, controlling the first read-write module 11 to be started and controlling the second read-write module 12 to be stopped, and then entering step S13.

S13, acquiring the monitoring data of the first read-write module 11, acquiring the label information of all the electronic labels in the label box 10, and then entering step S14.

S14, judging whether the electronic tag in the tag box 10 is taken out, if so, proceeding to a step S15, and if not, repeating the step S14.

And S15, when the fact that the electronic tag in the tag box 10 is taken out is detected, controlling the first reading and writing module 11 to stop, and starting the second reading and writing module 12, so that food editing operation is carried out on the taken out electronic tag by utilizing the second reading and writing module 12.

For example, the first read-write module 11 provided in the tag box 10 reads tag information of the electronic tags in the tag box 10 every a period of time (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 tag data (for example, a comparison identification code) two times before and after the tag information is compared. When it is monitored that an electronic tag is taken out from the tag box 10, it indicates that the user needs to use the electronic tag at this time, and at this time, food binding operation needs to be performed, so that the first read-write module 11 is closed, 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 management system is initialized, and in subsequent use, the first read-write module 11 and the second read-write module 12 are started in turn, and one is closed when the other works, 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: the tag information corresponding to all the electronic tags in the tag box 10 read and written by the first read-write module 11 is stored in a preset non-stored food database; the electronic tag is provided with a display screen for displaying food material information, and the tag information comprises an identification code of the electronic tag and the corresponding food material information;

upon detecting that an electronic tag is removed from the tag cassette 10, the controller 13 is further configured to: and acquiring food material information of the extracted electronic tag from the non-stored food material database, and deleting the food material information of the extracted electronic tag from the non-stored food material database.

For example, referring to fig. 7, fig. 7 is a second workflow diagram of the controller 13 in the refrigerator according to the embodiment of the present invention, where the controller 13 is further configured to perform step S131 after performing step S13:

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

The controller 13 is further configured to perform step S141 after performing step S14:

s141, acquiring food material information of the extracted electronic tag from the non-stored food material database, deleting the food material information of the extracted electronic tag from the non-stored food material database, and then proceeding to step S15. When it is detected that an electronic tag is taken out, it means that the electronic tag needs to be bound with food materials, and therefore, the tag information corresponding to the electronic tag needs 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 extracted electronic tag within a preset time period, starting a tag information editing mode; and if the second read-write module 12 does not read the extracted electronic tag within a preset time period, storing the food material information of the extracted electronic tag into the stored food material database.

Referring to fig. 8, fig. 8 is a third workflow diagram of the controller 13 in the refrigerator according to the embodiment of the present invention, after step S15 is performed, the controller 13 is further configured to perform steps S16 to S19:

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

S17, judging whether the second read-write module 12 reads the extracted electronic tag within a preset time period, if so, entering a step S19, and if not, entering a step S18.

And S18, if the second read-write module 12 does not read the extracted electronic tag within a preset time period, storing food material information of the extracted electronic tag into the stored food material database.

And S19, if the second read-write module 12 reads the extracted 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 extracted electronic tag within the preset time period, it indicates that the extracted electronic tag may be directly applied to the food to be bound without editing by the user, and because the electronic tag is provided with the display screen, the user may directly see the food information written by the electronic tag on the display screen, and if the information corresponds to the food to be bound, the user may directly apply the information without performing the tag information editing mode. It can be appreciated that, for the electronic tag in which the user does not perform the 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 (without manual operation) in the food material information, 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 edit food materials on the electronic tag taken out of the tag box 10; when receiving a voice command which is replied by a user and does not need to be changed, storing food material information of the extracted electronic tag into the stored food material database; when a voice command to be changed, which is replied by a user, is received, a voice editing command of the user is collected, corresponding food material information is written into the electronic tag according to the voice editing command, and the food material information of the electronic tag after editing is stored in a preset stored food material database.

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, sending out voice prompt information, and then proceeding to step S192 or step S193.

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

S193, when a voice command to be changed, which is replied by the user, is received, a voice editing command of the user is collected, and then the step S194 is carried out.

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

For example, if the second read/write module 12 reads the extracted electronic tag within a preset period of time (the user brings the electronic tag close to the second read/write module 12), it indicates that the user needs to edit/confirm the food information recorded in the first electronic tag at this time, and then a tag information editing mode is started. The user may also start the tag information editing mode without changing the tag information, which may be caused by false triggering, so that after receiving the voice prompt (for example, asking the user whether to change the food material information), the user may feedback a voice command without changing, and at this time, the food material information of the taken out electronic tag may be directly stored in the stored food material database. When receiving a voice command which is returned by a user and needs to be changed, editing food material information according to voice information fed back by the user, and storing the food material information of the electronic tag after editing into a preset stored food material database.

Specifically, after the second read/write module 12 is started, the controller 13 is further configured to: when it is detected 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 by one, the second read-write module 12 is controlled to stop, and the first read-write module 11 is started.

Referring to fig. 10, fig. 10 is a fifth operation flowchart of the controller 13 in the refrigerator according to the embodiment of the present invention, wherein the controller 13 is further configured to perform step S20:

and S20, controlling the second read-write module 12 to stop and starting the first read-write module 11 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 by one.

For example, when it is detected that the tag information written in the stored food material database corresponds to the tag information deleted in the non-stored food material database, it indicates that the tags removed from the tag box 10 by the user have all been re-entered into the stored food material database, that is, the binding of the food materials has been completed, for example, it is detected that two electronic tags in the tag box 10 are removed, the tag information stored in the non-stored food material database by the two electronic tags is deleted at this time, and because the controller 13 acquires the tag information of the two electronic tags together, the tag information of the two electronic tags is written in the stored food material database, which indicates that the food materials corresponding to the two electronic tags are already stored in the refrigerator, at this time, the second read-write module 12 needs to be controlled to be stopped, the first read-write module 11 is started, and then the steps S13 to S20 are continuously performed.

Referring to fig. 11, fig. 11 is a schematic information interaction diagram of a refrigerator and a client provided by an embodiment of the present invention, and the refrigerator 100 establishes a data connection with the client 200 through a router 300 or a cloud server 400. When the refrigerator 100 and the client 200 communicate through the router 300, the refrigerator 100 and the client 200 are closely spaced, and a user can view the operation condition of the refrigerator or the storage condition of food materials placed in a kitchen in a living room or a room. When the refrigerator 100 and the client 200 communicate through the cloud server 400, the refrigerator 100 and the client 200 are far apart, and a user can perform data interaction with the refrigerator 100 through an APP installed in the client 200, and meanwhile, remote control of the refrigerator 100 can be realized.

Compared with the prior art, the refrigerator disclosed by the invention is provided with the food material management system comprising the label box, the first reading and writing module and the second reading and writing module; the first reading and writing module is arranged in the tag box and works in a multi-tag reading and writing mode, and the second reading and writing module is arranged outside the tag box and works in a single-tag reading and writing mode. By arranging the read-write modules at different space positions and controlling the working logic of the read-write modules, the defects of mutual interference and reduced recognition rate caused by superposition of induction electromagnetic fields of a plurality of read-write modules are effectively avoided, and the problems of material cost increase and complex process caused by isolation by adopting shielding materials are solved.

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

s1, when the power-on initialization of the food management system is detected, controlling the first read-write module to start and controlling the second read-write module to stop;

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

and S3, when the fact that the electronic tag in the tag box is taken out is detected, controlling the first reading and writing module to stop, and starting the second reading and writing module to conduct food editing operation on the taken-out electronic tag by utilizing the second reading and writing module.

The first read-write module provided in the tag box reads tag information of the electronic tags in the tag box every a period of time (for example, 1 s), and can know which electronic tags are taken out or which electronic tags are newly added into the tag box by comparing tag data (for example, a comparison identification code) before and after two times. When the electronic tag is monitored to be taken out of the tag box, the electronic tag is required to be used by a user at the moment, and food binding operation is required at the moment, so that the first reading and writing module is closed, and the first reading and writing module is prevented from influencing the reading and writing process of the second reading and writing module.

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

storing label information corresponding to all electronic labels in the label box read and written by the first reading and writing module into a preset non-stored food database; the electronic tag is provided with a display screen for displaying food material information, and the tag information comprises an identification code of the electronic tag and the corresponding food material information; upon detecting that an electronic label is removed from the cassette, the controller is further configured to: and acquiring food material information of the extracted electronic tag from the non-stored food material database, and deleting the food material information of the extracted electronic tag from the non-stored food material database.

Illustratively, the tag information of all electronic tags placed in the tag cassette is stored in an unstored food material database. When it is detected that an electronic tag is taken out, it means that the electronic tag needs to be bound with food materials, and therefore, the tag information corresponding to the electronic tag needs 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 extracted electronic tag in a preset time period, starting a tag information editing mode; and if the second read-write module does not read the extracted electronic tag within a preset time period, storing the food material information of the extracted electronic tag into the stored food material database.

The second reading and writing module is used for reading the electronic tag, and the second reading and writing module is used for reading the electronic tag, so that the electronic tag can be directly applied to the food material to be bound after the electronic tag is read by a user. It can be understood that, for the electronic tag in which the user does not perform the 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 (without manual operation) in the food material information, 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 food editing operation is required to be carried out on the electronic tag taken out from the tag box or not; when receiving a voice command which is replied by a user and does not need to be changed, storing food material information of the extracted electronic tag into the stored food material database; when a voice command to be changed, which is replied by a user, is received, a voice editing command of the user is collected, corresponding food material information is written into the electronic tag according to the voice editing command, and the food material information of the electronic tag after editing is stored in a preset stored food material database.

For example, if the second reading and writing module reads the extracted electronic tag within a preset time period (the user brings the electronic tag close to the second reading and writing module), it indicates that the user needs to edit/confirm the food information recorded in the first electronic tag at this time, and then a tag information editing mode is started. The user may also start the tag information editing mode without changing the tag information, which may be caused by false triggering, so that after receiving the voice prompt (for example, asking the user whether to change the food material information), the user may feedback a voice command without changing, and at this time, the food material information of the taken out electronic tag may be directly stored in the stored food material database. When receiving a voice command which is returned by a user and needs to be changed, editing food material information according to voice information fed back by the user, and storing the food material information of the electronic tag after editing into a preset stored food material database.

When it is detected 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 by one, the tag information of the two electronic tags is written in the stored food material database, which indicates that the tag taken out of the tag box by the user has been re-recorded in the stored food material database at this time, that is, the binding of the food materials has been completed, for example, it is detected that two electronic tags in the tag box are taken out, the tag information stored in the non-stored food material database by the two electronic tags is deleted at this time, and the controller acquires the tag information of the two electronic tags together, so that the tag information of the two electronic tags is written in the stored food material database, which indicates that the food materials corresponding to the two electronic tags are stored in the refrigerator, and at this time, the second reading and writing module is required to be controlled to stop, and the first reading and writing module is started.

It should be noted that, in the method for managing food material labels in a refrigerator according to the embodiment of the present invention, a specific working process may refer to a working process of a controller in a refrigerator according to the above embodiment, and will not be described herein.
