As shown in fig. 1a and 1b, in the refrigerator provided in the embodiment of the present application, at least two storage compartments, such as a freezing compartment, a refrigerating compartment, a temperature changing compartment, and/or a fresh food compartment, are provided inside a refrigerator body. Each storage compartment may have a plurality of separate storage spaces therein, such as drawer compartments.

Fig. 2 is a schematic diagram of a hardware configuration of a refrigerator according to an exemplary embodiment of the present application, and as an example, a refrigerator 200 may include a display screen 210, a controller 220, at least one RFID detection module 230, a detector 240, a memory 250, and several user input interfaces. Display screen 210, RFID detection module 230, detector 240, and memory 250 are coupled to controller 220 via a communication interface. The display 210 is configured to receive the image signal output by the controller 220, perform a component for displaying video content and images and a menu manipulation interface, and display a user manipulation UI interface for controlling the refrigerator 200.

The controller 220 may include one or more processing units, such as a system on a chip (SoC), a Central Processing Unit (CPU), a Microcontroller (MCU), a memory controller, and the like. The different processing units may be separate devices or may be integrated into one or more processors.

The memory 250 may include one or more memory units, for example, may include a volatile memory (volatile memory), such as: dynamic Random Access Memory (DRAM), Static Random Access Memory (SRAM), and the like; non-volatile memory (NVM) may also be included, such as: read-only memory (ROM), flash memory (flash memory), and the like. The different memory units may be separate devices, or may be integrated or packaged in one or more processors or communication interfaces, and become a part of the processors or communication interfaces.

The memory 250 has stored therein program instructions and application programs such as voice applications. The controller 220 may call the program instructions in the memory 250 or run an application program, so that the refrigerator executes a related method, for example, the food material information editing method provided in the embodiment of the present application.

The detector 240, including at least a sound collector such as a microphone, may be used to receive the user's voice. Illustratively, a voice signal including a control instruction of the user controlling the refrigerator 200.

A user input interface including at least one of a microphone, a touchpad, a sensor, a key, and other input interfaces. Such as: the user can realize a user instruction input function through actions such as voice, touch, gesture, pressing, and the like, and the input interface converts the received analog signal into a digital signal and converts the digital signal into a corresponding instruction signal, and sends the instruction signal to the refrigerator 200.

In some embodiments, the controller 220 may include a voice recognition module, and the voice recognition module further includes a voice parsing unit and a voice command database, so that the refrigerator can independently perform voice recognition of voice data input by a user and a process of matching recognized voice contents with voice commands in the voice command database.

The RFID detection module 230 may be disposed in each storage compartment, and configured to transmit a wireless signal in the corresponding storage compartment and receive a signal of the RFID tag in the storage compartment, so as to obtain a food material code of the RFID tag.

In some embodiments, the refrigerator further includes a tag reading area provided outside the storage compartment, i.e., a sensing area for identifying the RFID tag, and an RFID detection module is provided at the tag reading area for detecting the RFID tag placed in the area. Alternatively, the tag reading area may be disposed below the display screen so that the user can simultaneously place (or remove) the RFID tag in the tag reading area and operate the user interface displayed on the display screen.

In some embodiments, the refrigerator may further include an RFID processing module, which is respectively connected to each RFID detection module, and configured to control the RFID detection module to transmit a wireless signal and receive a signal of the RFID tag fed back by the RFID detection module.

In some embodiments, the RFID detection module may be specifically an antenna. The power of the antennas provided in different storage compartments may be different. And the power of the antenna of each storage room can ensure that the antenna can identify the food materials in the self room, thereby avoiding that the error identification rate is increased when the power is too high and the food materials in the incomplete self room can be identified when the power is too low. In a specific implementation, the power of the antenna can be determined in advance according to the space size of each storage room, and the power of each antenna is set in the refrigerator, and the larger the space is, the larger the power is.

In order to realize intelligent management of food materials, the food materials in the storeroom are identified by using RFID labels.

In the prior art, the association between the RFID tag and the food material is realized by converting the food material type and/or the food material name into a corresponding food material code and writing the food material code into the RFID tag. For example, the RFID tag is placed in a designated area of the reading and writing device in advance, the food material type and/or food material name input by the user on the corresponding operation interface is received, the food material type and/or food material name input by the user is converted into a food material code, and the food material code is written into the RFID tag. The association method is not only complicated in operation, but also cannot be changed once the food material codes are written, so that the use flexibility of the RFID tag is poor, and the RFID tag cannot be recovered if the operation is wrong.

To solve the above problem, in some embodiments, by establishing a correspondence relationship between the RFID tag and the food material information, a virtual association between the RFID tag and the food material information is achieved without performing an operation of writing the food material information for each RFID tag. The corresponding relation between the RFID tags and the food material information can be modified, so that the same RFID tag sequentially corresponds to different food material information, and the use flexibility of the RFID tag is improved. And storing the food material attached with the RFID label in a refrigerator. The refrigerator acquires the tag code of the RFID tag by detecting the signal of the RFID tag, and determines the food material identified by the tag according to the food material information associated with the tag code.

In some embodiments, the virtual association between the RFID tags and the food material information is realized by establishing the corresponding relationship between the RFID tags and the food material information, and the same RFID tag sequentially corresponds to different food material information by modifying the corresponding relationship between the RFID tags and the food material information, so that the use flexibility of the RFID tag is improved. For example, a corresponding relationship between identification information of the RFID tag and food material information is established, so as to implement virtual association between the RFID tag and the food material. The identification information of the RFID tag may be a tag code of the RFID tag identified by the RFID detection module 230, or may be a code segment in the tag code. In these embodiments, the controller 220 may determine the food material information corresponding to each RFID tag according to the identification information of each RFID tag and the pre-established correspondence relationship.

For example, the correspondence relationship between the identification information of the RFID tag and the food material information established in advance may be shown as the following table:

RFID	food material information
		Identification
1	Apple (Malus pumila)
		Identification 2	Cucumber (Cucumis sativus)
Identification 3	Pork
		……	……

After the corresponding relationship between the RFID tags and the food material information is established, the controller 220 obtains the tag codes of the RFID tags by detecting the signals of the RFID tags, and the food material information associated with each tag can be determined according to the tag codes.

In some embodiments, the food material information associated with each tag is associated with a storage chamber, and the storage location of the food material can be determined according to the storage chamber associated with the food material information, for example, if the food material information "apple" is associated with "refrigerator", it can be determined that the apple is stored in the refrigerator.

In some embodiments, a food material management interface is displayed on the display screen 210, and the user manages food materials in the refrigerator by operating the food material management interface. For example, corresponding food material controls/icons are drawn in the food material management interface according to the food material information associated with each RFID tag in the storage room, so that the food materials in the refrigerator are displayed in the forms of icons, pictures and texts, and the like. In addition, functional controls, such as an RFID tag identification control, a food material addition control, and the like, can be drawn in the food material management interface, so that a user can operate the functional controls to trigger the controller 210 to implement corresponding functions.

In some embodiments, the food material management interface may include a plurality of food material display areas, one food material display area may correspond to one storage chamber, and the food material information associated with each storage chamber is displayed in the food material display area corresponding to each storage chamber, that is, the food material in the refrigerator is displayed in different areas in the food material management interface. For example, the food material information associated with the refrigerating chamber is displayed in the food material display area corresponding to the refrigerating chamber. The food material information displayed in the food material management interface includes, but is not limited to, a food material icon, a food material name, and a freshness identifier of a food material, wherein the food material icon can be generated according to a pictographic picture of the food material, and the freshness identifier of the food material is used for showing any one or more of the placement time, the remaining time when the distance is expired, and the expiration time of the food material. It is to be understood that the food material name, the freshness identification of the food material, etc. may be part of, i.e. comprised in, the food material icon.

Fig. 3 is a user interface according to an exemplary embodiment of the present application, which is specifically an exemplary food material management interface. Referring to fig. 3, the food material management interface includes an RFID tag editing control, a recommended menu control, and food material display areas corresponding to the storage chambers, such as the food material display area 310 corresponding to the refrigerating chamber, where a corresponding food material icon, such as the food material icon "apple" 311 in the food material display area 310, is displayed in each food material display area.

In some embodiments, the RFID tags may be divided into custom tags and predefined tags, where a custom tag refers to a tag where the associated food material name is customizable by the user, and a predefined tag refers to a tag where the associated food material name is not customizable by the user. The custom tag and the predefined tag may be distinguished according to tag coding.

In some embodiments, the tag code of the RFID tag includes at least two code segments, a first code segment and a second code segment, respectively. Wherein the first code segment is used for writing a first code, which may be a predetermined code or a non-predetermined code. For the RFID tag with the first code being the preset code, the corresponding food material information can be defined by a user, namely the RFID tag is a user-defined tag; for the RFID tag with the first code being the non-predetermined code, the corresponding preset food material information is pre-stored in the cloud server or the local food material library, and the RFID tag cannot be defined by a user, namely the RFID tag is the predefined tag. The second code segment is used for writing a second code which is the unique identification information of the RFID label. It should be noted that the user-defined food material name means that the user can associate any food material name with the RFID tag according to the requirement, and meanwhile, the user can change the defined tag according to the change of the requirement, so that the front and back of the same tag are associated with different food material names, while the user cannot define the food material name by the user, that is, the user cannot change the food material name associated with the RFID tag, and the food material name associated with the RFID tag is predefined and stored in the cloud server or the local food material library.

When an RFID tag is given, whether the tag is a predefined tag or a custom tag may be determined according to a first code included in the tag code. If the first code is a predetermined code, the tag is a custom tag, and if the first code is not the predetermined code, the tag is a predefined tag. In some embodiments, at least two code segments included in the tag code of the RFID tag conform to a preset composition rule, and after the tag code is obtained, the controller intercepts the first code segment and/or the second code segment according to the preset composition rule to obtain the first code and/or the second code, so that a process of analyzing long code information is saved, and processing efficiency is improved.

In some embodiments, the predetermined code has uniqueness, such as 00; the non-predetermined code has no uniqueness, and may be multiple, and one non-predetermined code corresponds to one food material information.

Illustratively, the tag encoding structure of an RFID tag is as follows:

for example, if the controller acquires that the tag code of the RFID tag is "01123456789012345678901234", the first code may be intercepted as "01" and the second code may be intercepted as "123456789012345678901234" according to the preset composition rule.

It should be noted that, according to different requirements, the tag code of the RFID tag may further include more code segments, such as a third code segment for writing the manufacturer identifier of the RFID tag, and further, such as a fourth code segment for serving as a reserved bit of the tag code, so as to improve the expandability of the RFID tag. In other embodiments, the manufacturer identifier of the RFID tag may also be included in the second code segment, which is not described herein.

For example, the correspondence relationship between the first code (non-predetermined code) and the food material information may be as shown in the following table:

RFID first code	Food material name
		01	Radish (radish)
02	Carrot (Carex sativus L.)
		03	Lotus root
……	……

In some embodiments, when the food material management interface is displayed on the display screen, a user may input an instruction indicating to perform food material information editing by operating the food material management interface, for example, the user clicks a food material information editing control provided by the food material management interface to indicate to perform food material information editing; after receiving the instruction, the controller starts to detect a signal of the RFID tag placed on the tag reading area to acquire identification information of the RFID tag, displays an interface for editing food material information associated with the RFID tag, namely a food material editing interface, and inputs the food material information associated with the RFID tag in the food material editing interface.

In some embodiments, the obtained identification information of the RFID tag can be displayed in the food material editing interface, so that a user can visually see the identification information of the RFID tag without manually inputting the identification information by the user, and the user experience is improved.

In some embodiments, at least one food material editing item is displayed in the food material editing interface, each food material editing item includes an item name and item content, where the item content is a portion to be edited, and a user can input food material information for associating with the RFID tag by inputting the item content of each food material editing item at an input position. After the input is finished, the controller correspondingly stores the input food material information and the identification information, so that the establishment of the corresponding relation table of the identification information of the RFID label and the food material information is finished and perfected.

In some embodiments, the interface for editing food material information may be referred to as a food material editing interface, and the food material editing items displayed thereon may include a food material name editing item, a food material shelf life editing item, a food material quantity editing item, and the like. It should be understood that the item name of the food material name editing item may be a "tag name", the item content is a name of the food material to be input or updated, the item name of the food material shelf life editing item may be a "shelf life", the item content is a shelf life to be input or updated, the item name of the food material quantity editing item may be a "quantity", and the item content is a quantity to be selected or changed.

As shown in fig. 3, a user may click on an RFID tag editing control in the interface to input an instruction instructing to edit food material information. In response to the instruction, the controller controls the RFID detection module to start detecting a signal of the RFID tag on the tag reading area to acquire identification information of the RFID tag. And after the controller acquires the identification information of the RFID tag, presenting a food material editing interface on the display screen.

In some embodiments, after the controller receives an instruction input by a user and instructing to edit food material information, a tag scanning interface is displayed in response to the instruction, a scanning prompt is displayed in the tag scanning interface, and the user is prompted to place an RFID tag to be edited on the tag reading area by displaying the scanning prompt. Meanwhile, the controller controls the RFID detection module to start detecting signals of the RFID tags on the tag reading area so as to acquire identification information of the RFID tags. And after the controller acquires the identification information of the RFID tag, presenting a food material editing interface on the display screen.

In some embodiments, the user may also instruct the instruction for editing the food material information by speaking a preset voice password. For example, the user speaks: "tag editing". When voice data input by a user is received and the content is recognized as 'tag editing', the fact that an input preset voice instruction for triggering the food material information corresponding to the RFID tag to be edited is received is confirmed. At this time, the controller displays a tag scanning interface in response to the instruction, and starts detecting the RFID tag on the tag reading area.

In some embodiments, when an input preset voice command is received, it is first determined whether an RFID tag on a tag reading area is detected, and if the RFID tag on the tag reading area is not detected, it indicates that a user has not placed an RFID tag to be edited on the tag reading area, and at this time, a tag scanning interface including a scanning prompt is displayed to prompt the user to place the RFID tag to be edited on the tag reading area.

In some embodiments, the instruction for instructing to edit the food material information is also referred to as an RFID tag editing instruction.

Fig. 4 is a user interface, specifically an exemplary label scanning interface, shown in some embodiments of the present application, and as shown in fig. 4, a scan prompt is displayed on the label scanning interface, and its specific content is "please prevent the RFID label from being scanned in the area below the screen". When the RFID tag placed on the tag reading area by the user is detected, a food material editing interface as shown in fig. 5 is displayed.

Referring to fig. 5, the identification information "20200005" of the RFID tag is displayed on the food material editing interface, so that the user does not need to manually input the identification information, thereby avoiding input errors and saving user operations. On the food material editing interface, a plurality of food material editing items are displayed, namely a food material name editing item "tag name" 510 and a food material quality guarantee period editing item "quality guarantee period" 520, wherein each food material editing item corresponds to an input position for inputting the content of the corresponding item. And, a "cancel" control 530 and a "determine" control 540 are displayed.

Therefore, each RFID tag corresponds to the food material information input by the user, virtual association between the RFID tag and the food material information is realized, the corresponding food material information can be found according to the identification information of the RFID tag, the corresponding relation between the RFID tag and the food material information can be modified, the same RFID tag sequentially corresponds to different food material information, and the use flexibility of the RFID tag is improved.

In some embodiments, the identification information of the RFID tag may not be displayed in the food material editing interface.

In some embodiments, the user may edit the food material information corresponding to the RFID tag through a voice instruction, for example, the user may say: the controller can automatically update the project contents of the corresponding food material editing project according to the recognized voice contents of beef, beef of 2 jin and the like without inputting characters by a user. Therefore, user operation can be further reduced, the editing process is quicker, the universality degree of the function can be improved, and old people or children who cannot type can also edit food material information.

In some embodiments, when the controller detects that the user places the RFID tag on the tag reading area, while displaying the food material editing interface, a voice recognition interface is displayed, and starts to receive and recognize the voice input of the user, where the voice recognition interface may display an input prompt and recognized voice content; and updating the item content of the food editing item in the interface according to the recognized voice content.

In some embodiments, the user interface may include multiple view display areas, different view display areas may partially overlap or completely do not overlap, and different view display areas may be areas belonging to the same layer or areas belonging to different layers. In the application, the food material editing interface and the voice recognition interface can be respectively displayed in two different view display areas in the user interface.

Fig. 6 is a user interface shown in some embodiments of the present application, specifically, a user interface displaying a food material editing interface and a voice recognition interface at the same time, where as shown in fig. 6, a view display area 610 where the voice recognition interface is located is displayed on an upper layer of a view display area 620 where the food material editing interface is located, and an input prompt is displayed in the voice recognition interface, specifically, a text prompt indicating that "you can say i want to define 2 jin of juicy peaches" is included. When voice data input by a user is received and voice content is recognized, the voice recognition interface can also display the recognized voice content.

In some embodiments, the controller receives voice data input by a user, and sends the voice data to the server; the server identifies the voice data to obtain corresponding voice content, and generates a voice instruction according to the voice content, wherein the voice instruction comprises a plurality of fields, one field corresponds to one food material editing item, the field name is an item name, and the field value is item content. And the server returns the generated voice instruction to the refrigerator, and the refrigerator updates the item content of the corresponding food material editing item according to the field value of each field in the voice instruction.

An exemplary voice instruction format is as follows:

name of field	Field value
		cmd	RFID-write
name	Beef
		count	1000g

As can be seen from the above voice instruction, the voice instruction instructs the refrigerator to perform an RFID tag editing operation, where a field value "beef" corresponding to the field name "is used to update the item content of the food material name editing item, and a field value" 1000g "corresponding to the field name" count "is used to update the food material quantity editing item.

In some embodiments, after the controller detects that the RFID tag is placed on the tag reading area by a user, it is determined whether the RFID tag is a custom tag, and if the RFID tag is the custom tag, a first editing interface is displayed, where the first editing interface includes a plurality of food material editing items, where a preset default character is displayed in an item content display area (i.e., an input position area) corresponding to each food material editing item, and item content of each food material editing item is editable. In this way, the user can update the item content of each food material editing item by inputting characters or inputting voice. And if the RFID tag is not a self-defined tag, acquiring preset food material information corresponding to the tag according to a first code in the tag code, and displaying a second editing interface according to the acquired preset food material information. Different from the first editing interface, in the second editing interface, preset food material information, such as preset food material names, is displayed in the item content display area corresponding to each food material editing item, and the item content of the food material name item is not editable, that is, the user cannot change the currently displayed food material name by inputting characters or inputting voice.

In specific implementation, the controller can acquire corresponding preset food material information from the cloud server according to the first code. Or, the controller may obtain the corresponding preset food material information from a locally preset food material library according to the first code. The food material library preset locally can be obtained by downloading the controller from a cloud server in advance.

In some embodiments, if the RFID tag placed on the tag reading area by the user is a custom tag, it is determined whether the food material information corresponding to the second code exists in the local data according to the second code (i.e., the identification information of the RFID tag) in the tag code, and if the food material information corresponding to the second code exists in the local data, the food material information is displayed in the first editing interface as the item content of each food material editing item. Therefore, on one hand, the currently associated food material information of the RFID tag can be displayed to the user, and on the other hand, if the user wants to modify the currently associated food material information, new food material information can be input through a character input operation or a voice input operation. In addition, if the user only wants to modify part of the food material information, the user only needs to re-input the part of the food material information, and the user does not need to re-input the other part of the food material information which is not wanted to be modified. And if the food material information associated with the RFID tag does not exist in the local data, displaying preset default characters as the item content of each food material editing item in a first editing interface.

Fig. 7 is a possible user interface shown in some embodiments of the present application, which is specifically an exemplary first editing interface, as shown in fig. 7, in which the item content of each food material editing item is a default character "undefined".

Fig. 8 is a possible user interface, specifically an exemplary second editing interface, shown in some embodiments of the present application, in which, as shown in fig. 8, the item content of the food material name editing item 810 is a default character "apple", the item content of the shelf life editing item 820 is a default character "1", and the item content of the food material quantity editing item 830 is a default character "1". The "apple", "1", and the like are preset food material information corresponding to the currently detected tag.

As mentioned above, for predefined tags, their associated food material names are not editable, and for custom tags, their associated food material names are editable. Based on the above, when the refrigerator controller updates the food material editing items according to the voice command returned by the server, if the RFID tags are the custom tags, all the contents of the food material editing items are updated, and if the RFID tags are not the custom tags, the contents of the items of the food material editing items other than the food material name editing items are updated.

For example, assuming that the currently detected RFID tag is a custom tag, and the voice instruction returned by the server includes fields "name, beef", "shelf life, 60 days", "number, 1000 g", the editing interface shown in fig. 7 is updated according to the voice instruction to display the editing interface shown in fig. 9, "beef" is displayed at the input position corresponding to the food material name editing item 910, "60 days" is displayed at the input position corresponding to the shelf life editing item 920, and "1000 g" is displayed at the input position corresponding to the food material number editing item 930; assuming that the currently detected RFID tag is not a custom tag, the editing interface shown in fig. 7 is updated according to the voice instruction to display the editing interface shown in fig. 10, "60 days" is displayed at the input position corresponding to the shelf life editing item 102, and "1000 g" is displayed at the input position corresponding to the food material quantity editing item 103, without updating the display of "apple" in the food material name editing item 101.

In addition, if the RFID tag is not a custom tag, the refrigerator controller may further determine whether a field value corresponding to the field name "in the voice instruction is the same as a preset food material name of the RFID tag, and when the field value is different from the preset food material name of the RFID tag, pop up a text prompt on a user interface, or play a voice prompt to prompt a user that the RFID tag does not support editing of the food material name.

With the example shown in fig. 10, since the preset food material name corresponding to the currently detected RFID tag is "apple", which is different from "beef" in the voice instruction, a text prompt needs to be popped up or a voice prompt needs to be played. If the preset food material name corresponding to the currently detected RFID tag is beef, the field value corresponding to the field name in the voice instruction is beef, so that a text prompt does not need to be popped up or a voice prompt does not need to be played.

In some embodiments, the food material editing interface further includes a designated control for triggering storage of the input food material information, and when the refrigerator controller receives a confirmation operation of a user on the designated control, the refrigerator controller responds to the confirmation operation and generates food material information according to item contents updated by all food material editing items; and correspondingly storing the food material information and the tag codes of the RFID tags in local data so as to finish the process of associating the food material information edited by the user with the RFID tags. Furthermore, the food material information related to the tag can be obtained from the local data according to the tag code of the tag. The food material information generated according to the item content updated by all food material editing items comprises food material names, shelf lives and food material numbers, and can also comprise food material IDs generated according to the current time.

As shown in fig. 5, the food material editing interface includes a "cancel" control 530 and an "confirm" control 540, and a user can trigger the refrigerator to generate food material information according to the item content updated by all food material editing items by touching the "confirm" control; and correspondingly storing the food material information and the tag code of the RFID tag in local data.

In the above embodiment, whether the food material information corresponding to the RFID tag is customizable by the user is determined according to whether the first code is a predetermined code, if the first code is the predetermined code, it is indicated that the food material information corresponding to the RFID tag is customizable by the user, at this time, the first editing interface is displayed according to preset default characters, after the food material information input by the user is received, each food material editing item in the first editing interface is updated according to the food material information, and the received food material information corresponds to the RFID tag, so that the use flexibility of the RFID tag is improved. If the first code is not the preset code, the fact that the food material information corresponding to the RFID tag cannot be defined by a user is indicated, the corresponding preset food material information is obtained according to the first code, a second editing interface is displayed according to the preset food material information, after the food material information input by the user is received, the information except the preset food material name in the preset food material information is updated according to the food material information, the updated food material information corresponds to the RFID tag, user operation is saved, and the efficiency of editing the food material information is improved.

In some embodiments, a user may first place an RFID tag to be edited on the tag reading area, and at this time, the controller detects the RFID tag and displays the food material editing interface. Then, the user speaks a preset voice password to input a preset voice instruction, wherein the preset voice instruction comprises food material information to be edited by the user, such as saying "i want to define 2 jin beef". In other embodiments, a user may speak a preset voice password before placing an RFID tag to be edited in the tag reading area to input a preset voice instruction, where the preset voice instruction is used to trigger an editing process and includes food material information to be edited by the user, such as "i want to define 2 jin beef".

When the controller receives the preset voice command, each item of food material information contained in the command is packaged in a Bundle data structure, and each item of food material information in the structure comprises a Key Value and a Value, for example, the name of the food material corresponds to (Key _ name, Value _ beef), and the number of the food material corresponds to (Key _ count, Value _1000 g). Meanwhile, whether the currently displayed user interface is a food material editing interface is judged. If the currently displayed user interface is a food material editing interface, it is indicated that the user has placed an RFID tag to be edited in a tag reading area and has detected the tag, at this time, the controller updates the item content of each food material editing item in the food material editing interface according to the voice content included in the preset voice instruction, that is, updates the item content of each food material editing item according to the Value corresponding to each Key Value in the Bundle data; if the currently displayed user interface is not the food material editing interface, the fact that the user does not place the RFID tag to be edited in the tag reading area is indicated, and at the moment, a tag scanning interface containing scanning prompts is displayed to show that the user places the RFID tag to be edited in the tag reading area; and when the RFID tag placed on the tag reading area by the user is detected, displaying the item content of each food material editing item in the food material editing interface according to the voice content contained in the preset voice instruction.

It should be understood that, for example, when the RFID tag is a custom tag, all food material editing items are updated, when the RFID tag is not a custom tag, food material editing items other than the food material name editing item are updated, and the like, which are not described herein again, the process of displaying or updating the item content of each food material editing item according to the voice content included in the preset voice instruction may be referred to as the embodiment shown in fig. 1a to 10.

It can be seen from the above embodiments that, based on the refrigerator provided by the embodiments of the present application, a user can edit food material information corresponding to the RFID tag through voice input. Specifically, when detecting that the user places the RFID label on the label reading area, when showing edible material editing interface, show speech recognition interface, switch the pronunciation application to the proscenium operation promptly automatically to enter into the pronunciation detection state fast, in time detect user's speech input, the user is through saying the edible material information that wants to edit, can make the automatic information input process that accomplishes of refrigerator, saves user operation, and makes the editing process more swift, improves user experience.
