Usually, a refrigerator with a food material management function implements the food material management function through a label, and the label is provided with default label information. For example, before the label leaves the factory, default label information is set in the label in advance. The default label information cannot be modified.

In some examples, the default tag information for a tag may include an ingredient category. According to the ingredient, the user can select a tag corresponding to the ingredient category of the ingredient to bind the ingredient for ingredient management. The ingredient category may be different from the ingredient. For example, the ingredient category may be meat, vegetables, fruits, etc., and each ingredient category includes different ingredients. Alternatively, the ingredient category may be the same as the ingredient, for example, the ingredient category may be beef, broccoli, apple, and the like. The embodiment of the present disclosure uses the food category and the food as examples for illustration. For example, when the user needs to put beef in the refrigerator, he can select a label whose ingredient category is beef and bind it to beef.

In some other examples, the default tag information of the tag may include storage compartment information. For example, the storage room information on the label includes: refrigerator room, freezer room or variable temperature room, etc. According to the compartment where the ingredients need to be placed, the user can select the label corresponding to the compartment to bind the ingredients for ingredient management. For example, when the user needs to place the broccoli in the cold room of the refrigerator, select a label whose storage compartment information in the label is the cold room to bind with the broccoli.

However, when the labels corresponding to a certain ingredient category and/or storage compartment information are insufficient, and the labels corresponding to other ingredient categories and/or storage compartment information are redundant, due to the ingredient category and/or storage compartment information in other labels The information cannot be modified, so the multiplexing of tags cannot be realized. For example, if the default storage room for a certain label is the refrigerator, no matter the user actually puts the label in the refrigerator or the freezer, the refrigerator will default that the label is managed in the refrigerator, so that the label can only be stored in the refrigerator by default. It can be used in separate compartments and cannot be used across compartments, resulting in low flexibility in ingredient management.

To this end, an embodiment of the present disclosure provides a refrigerator. As shown in FIG. 1 , a refrigerator 1 includes a box body 10 , a plurality of tags 20 , a first reader-writer 30 and a controller 40 .

In some embodiments, the case 10 includes a plurality of compartments 11 . For example, the plurality of compartments 11 may include compartment 111 , compartment 112 and compartment 113 . Compartment 111 may be a refrigerated chamber for refrigerated storage of food; compartment 112 may be a variable temperature chamber for variable temperature storage of food; compartment 113 may be a freezing chamber for frozen storage of food.

Exemplarily, referring to FIG. 2 , the box body 10 further includes a plurality of door bodies 12 , and the plurality of door bodies 12 correspond to the plurality of compartments 11 . For example, the door body 121 corresponds to the compartment 111 , the door body 122 corresponds to the compartment 112 , and the door body 123 corresponds to the compartment 113 .

It should be noted that when the user stores food in the compartment 11 or takes out the food from the compartment 11 , the label 20 fixed on the food can be put in or taken out together.

Exemplarily, the multiple tags 20 may be UHF radio frequency identification (Radio Frequency Identification, RFID) tags, or near field communication (Near Field Communication, NFC) tags. In some examples, the label 20 may include a label body detachably fixed on the food material. For example, the label body can be configured as a sealing clip, which can be clamped on both sides of the food material. For another example, the label body may include a sticking part, and the sticking part may stick the label body on the food material.

In some embodiments, plurality of tags 20 includes a first tag. Exemplarily, as shown in FIG. 2 , at least one first label 210 of the plurality of labels 20 is disposed in each compartment 11 .

In some examples, the first tag 210 may be a tag stored in the compartment 11 , and since the first tag 210 is stored in the compartment 11 , the first tag 210 may also be called a tag in use. In some embodiments, the first reader 30 is coupled to at least one first tag 210 and configured to read tag information of at least one first tag 210 in each compartment 11 .

As shown in FIG. 1 , the first reader-writer 30 may be arranged on the box body 10 . Exemplarily, the first reader-writer 30 may include a first read-write host and a first antenna. The first read-write host can control the first antenna to send a radio frequency signal to the first tag 210 in each compartment 11. After receiving the radio frequency signal, the first tag 210 sends its tag information to the first reader through the first antenna. write host. Therefore, the first reader-writer 30 can perform information interaction with the first tag 210 , and can acquire tag information of the first tag 210 .

In some embodiments, as shown in FIG. 3 , each tag 20 may include a memory 21 , a selector 22 and a processor 23 . Wherein, the memory 21 is configured to store label information of the label 20, and the label information includes a label identification and ingredient information.

In some examples, the memory 21 may be a memory chip. Wherein, the tag identifier in the tag information may be information used to identify each tag 20, for example, the tag identifier may be a tag ID (Identity Document, ID). The label identification of each label 20 is different, and the label identification may be the unique identification information of each label 20 .

The ingredient information may include information such as ingredient category, storage room, and shelf life. In some examples, information such as food category, storage compartment, and shelf life in the food information of the label 20 can be represented by 8-bit character strings. In some other examples, the ingredient information may also be represented by character strings of other lengths, which is not limited in the present disclosure.

Exemplarily, each label 20 may include marking information corresponding to different ingredient categories. The marking information of the food category may include, for example, pattern marking information and color marking information, and the user can quickly identify the food material category corresponding to the label through the marking information on the label 20 . Wherein, the tag information may also be represented by an 8-bit character string.

For example, when the label information of the label corresponding to the ingredient apple is 0000000000000001, the 1-8 digit string 00000000 may indicate that the storage room for the ingredient apple is a refrigerator, and the 8-16 digit string 00000001 may indicate that the ingredient category is apple. Other ingredients information such as shelf life, marking information, etc. can also be expressed in a similar way, and will not be repeated here.

In some embodiments, as shown in FIG. 3 , the memory 21 may include a first storage area 211 and a second storage area 212 . Wherein, the first storage area 211 is used to store the tag identification in the tag information. The second storage area 212 is used for storing ingredient information in the label information. In some examples, before the tag 20 leaves the factory, the tag ID is preset, and the tag ID is unique and can be used to identify the tag 20, so the tag ID of the tag does not need to be changed. However, some information in the food information, such as storage compartment information and food category information, may need to be changed, so as to improve the flexibility of food management in the refrigerator 1 . Therefore, the label identifier stored in the first storage area 211 does not need to be modified, and the ingredient information stored in the second storage area can be modified.

In some examples, the status of the second storage area 212 may include a read-only status and a read-write status. When the second storage area 212 is in the read-only state, the ingredient information stored in the second storage area 212 cannot be modified. When the second storage area 212 is in the read-write state, the ingredient information stored in the second storage area 212 can be modified.

In some embodiments, referring to FIG. 3 , the selector 22 is coupled to the memory 21 and is configured to select the state of the area where the ingredient information in the memory 21 is located.

Exemplarily, the selector 22 may be a toggle switch. The toggle switch may include a plurality of different switch positions, such as a first position and a second position. For example, the first gear may represent a read-only gear, and the second gear may represent a read-write gear. When the switching position of the rocking switch is at the first position, the read-only state of the area where the food material information is located in the memory 21 (that is, the second storage area 212 ) is selected. When the switching position of the rocker switch is at the second position, the reading and writing state of the area where the food material information is located in the memory 21 is selected, and at this time, the food material information stored in the second storage area 212 can be modified. Alternatively, the selector 22 can also be a slide switch, which can select different gear positions by sliding. The implementation of the slide switch is similar to that of the toggle switch, and will not be repeated here.

In some examples, the rocker switch may further include a marker indication area, and when the rocker switch is toggled to a different position, the marker indication area will display different marker indication information. For example, the marking indication information may be pattern marking information, or color marking information, or text marking information. For example, in the case where the mark indication information is pattern mark information, when the toggle switch is toggled to the first gear, the mark indication area can display the lock pattern corresponding to the read-only state; when the toggle switch is toggled to the second gear When the bit is in place, the mark indication area can display the unlock pattern corresponding to the read and write status. For another example, when the marking indication information is color marking information, when the toggle switch is toggled to the first gear, the marking indication area can display the red color corresponding to the read-only state; when the toggle switch is toggled to the second gear When the status is set, the mark indicator area will display green corresponding to the read and write status. In this way, the user can distinguish the current state of the second storage area 212 by marking different indication information of the indication area.

Exemplarily, the selector 22 may also be a key switch. For example, the selector 22 may include a plurality of different keys, such as a first key and a second key. Wherein, the function of the first button is similar to that of the above-mentioned first gear, and the function of the second button is similar to that of the above-mentioned second gear, which will not be repeated here. The following embodiments take a toggle switch as an example for illustration.

In some examples, the user can set the selector 22 according to requirements, so as to select different states of the second storage area 212 . For example, when the user needs to modify the corresponding ingredient information in a certain label 20, the selector 22 (such as a toggle switch) is toggled to the second gear, and at this time, the read-write state of the second storage area 212 is selected , that is, the selection result of the selector 22 on the state of the area where the food material information is located in the memory 21 is a read-write state. And, the selector 22 sends the selection result to the processor 23, and the selection result is the gear selected by the selector 22, such as the second gear.

In some embodiments, referring to FIG. 3 , the processor 23 is coupled to the selector 22 and is configured to set the state of the area where the ingredient information in the memory 21 is located according to the selection result of the selector 22; if the area where the ingredient information is located The status is reading and writing, and the information of the ingredients is modified.

In some examples, the processor 23 receives the selection result sent by the selector 22, and sets the state of the second storage area 212 according to the selection result. For example, when the processor 23 receives the selection result that the selector 22 is in the first gear, the second storage area 212 will be set to a read-only state; When the result is selected, the second storage area 212 will be set to read and write state. When the state of the second storage area 212 is set to the read-only state by the processor, the processor 23 cannot modify the material information in the second storage area 212; state, the processor 23 may modify the ingredient information in the second storage area 212 .

In some embodiments, the controller 40 is coupled to the first reader-writer 30 and is configured to receive an ingredient modification instruction, the ingredient modification instruction includes the target label identification and target ingredient information; according to the ingredient modification instruction, control the first reader-writer Send the target ingredient information to the processor in the first tag 210 corresponding to the target tag identifier, so that the processor in the first tag 210 updates the ingredient information stored in the first tag 210 to the target ingredient information to obtain the first tag 210 The updated label information for .

In some examples, controller 40 may be a chip or a processor. For example, the processor may be a general central processing unit (Central Processing Unit, CPU), a microprocessor, or an application specific integrated circuit (Application Specific Integrated Circuit, ASIC). Alternatively, the controller 40 may be a programmable device, including a complex programmable logic device (Complex Programmable Logic Device, CPLD), an erasable programmable logic device (Erasable Programmable Logic Device EPLD), or a field programmable gate array (Field Programmable Gate Array, FPGA). The chip may be an integrated circuit (Integrated Circuit, IC).

Exemplarily, the ingredient modification instruction may be an instruction for instructing the processor 23 in the first tag 210 to modify the ingredient information stored in the second storage area 212 of the memory 21 .

In some examples, the ingredient modification instruction may be sent to the server through an application program (Application, APP) installed on the terminal device for managing the refrigerator 1 . After receiving the ingredient modification instruction, the server sends the ingredient modification instruction to the controller 40 .

In some other examples, referring to FIG. 2 , the refrigerator 1 may further include an input device 50 . The input device 50 can also be referred to as an instruction generating device, and is used for receiving an input related instruction and sending the instruction to the controller 40 . The input device 50 may be a touch screen. For example, the user inputs an ingredient modification instruction in the input device 50 , and the input device 50 sends the ingredient modification instruction to the controller 40 .

The ingredient modification instruction may include target label identification and target ingredient information. For example, when the user needs to modify the ingredient information of a certain first label, he can input the label identification corresponding to the first label in the input device 50, the label identification corresponding to the first label can be called the target label identification, and input It is necessary to modify the ingredient information of the first tag into target ingredient information. For example, the ingredient category on the first label is beef, and the user needs to use the first label to bind broccoli, so the ingredient category beef on the first label needs to be changed to broccoli. In this case, the user needs to The label identifier of the first label and the target ingredient category broccoli (ie, the target ingredient information) are input into the input device 50 .

After receiving the ingredient modification instruction, the controller 40 may control the first reader/writer 30 to send the target ingredient information to the processor 23 of the first tag corresponding to the target tag identifier. For example, the controller 40 can send the target tag identification and target ingredient information to the first reader-writer 30, and the first reader-writer 30 finds the target first tag according to the target tag ID, and then sends the target ingredient information to the target first reader. Tag processor 23 . The processor 23 of the target first tag judges whether the state of the second storage area 212 in the memory 21 is a read-write state, and if the state of the second storage area 212 is a read-write state, the processor 23 stores the The original ingredient information of the target first tag is updated to the target ingredient information, and the updated tag information of the target first tag is obtained. For example, the processor 23 may change the ingredient category information beef stored in the second storage area 212 to broccoli. At this time, the ingredient category information of the target first label is updated to broccoli, realizing the multiplexing of labels.

To sum up, in the refrigerator 1 provided by the embodiment of the present disclosure, by adding a selector 22 to the label 20, the area in the memory 21 of the label 20 that stores food information is set to a modifiable read-write state, and then the controller 40 receives When modifying an instruction for food, the target food information is sent to the processor 23 of the label 20 corresponding to the label identification of the target food through the first reader-writer 30, so that the processor 23 controls whether to The target ingredient information is updated to the second storage area 212 , so as to realize modification of the ingredient information in the tag 20 . At the same time, the multiplexing of the labels 20 can also be realized, which improves the flexibility of ingredients management. In addition, if the state of the second storage area 212 is set as a read-only state, it can also prevent the tag information of the tag 20 from being changed by mistake.

In some embodiments, the controller 40 is further configured to: generate a material management list according to the label information of each first label 210; Updated tag information: update the tag information of the first tag 210 in the ingredients management list to the updated tag information of the first tag 210 .

In some examples, the ingredient management list may include label information of each first label 210 in the refrigerator 1 . Wherein, the ingredient management list can be generated by the controller 40 . For example, the controller 40 may acquire the tag information of each first tag 210 through the first reader/writer 30 , and generate a material management list through the tag information of each first tag 210 .

For example, referring to FIG. 4 , the controller 40 may send the generated ingredient management list to the server 3, and the server 3 stores the ingredient management list. Alternatively, the controller 40 may also send the ingredient management list to the storage device in the refrigerator 1, and the storage device of the refrigerator 1 stores the ingredient management list. For example, the ingredient management list can be stored in the form of a data table, which includes the label identification of the corresponding label of the ingredient and the ingredient information, wherein the ingredient information can be represented by an 8-bit character string, which will not be repeated here.

In some examples, the first reader-writer 30 reads the tag information of all the first tags 210 to obtain the tag information set of the first tag 210, and the first reader-writer 30 sends the tag information set to the controller 40, and the control The device 40 compares the tag information set with the ingredient management list, and obtains the first tag 210 corresponding to the tag identifier included in the tag information set but not included in the ingredient management list, and the first tag 210 can be considered as a new Put in the label. The controller 40 may update the tag information of the first tag 210 into the ingredient management list.

In other examples, the controller 40 may update the label information of the first label 210 according to the food item entry instruction to update the food material management list. The ingredient entry command is an instruction for instructing the controller 40 to record the tag information of the first tag 210 placed in the compartment 11 into the ingredient management list. The food input instruction can be input by the user through the input device 50 , or the food input instruction can also be triggered by opening the door body 12 , which is not limited in the present disclosure.

The controller 40 receives the ingredient entry instruction, and in response to the ingredient entry instruction, reads the updated tag information of the first tag 210 through the first reader/writer 30, and stores the original ingredient information of the first tag 210 in the ingredient management list. Update the target ingredient information to realize the synchronization of the ingredient management list and the tag information of the first tag 210 .

In some embodiments, the selector 22 of each tag 20 includes a plurality of selection ends, one of the plurality of selection ends corresponds to one of the plurality of compartments 11 . The selector 22 in the first tag 210 is also configured to: determine the target end from a plurality of selection ends of the first tag 210; the processor 23 in the first tag 210 is also configured to: The terminal determines the target compartment where the first tag 210 is located, and updates the storage compartment information in the first tag 210 to the compartment information of the target compartment.
