All other embodiments, which can be made by those skilled in the art based on the embodiments of the present invention without making any inventive effort, shall fall within the scope of the present invention.
Referring to fig. 1 to 3, the present application provides a refrigerator 100, the refrigerator 100 including a cabinet and a door 101 for opening and closing the cabinet. The storage compartment formed in the case may include a refrigerating compartment and a freezing compartment, and the door body 101 may include a refrigerating door body 101 for opening and closing the refrigerating compartment and a freezing door body 101 for opening and closing the freezing compartment. The refrigerator 100 may also be provided with a display screen 102, and a user may interact with the refrigerator 100 through the display screen 102. Or the refrigerator 100 may be provided with a voice module through which a user can interact with the refrigerator 100.
The refrigerator 100 can be internally provided with a WiFi module, data information in the refrigerator 100 can be transmitted to the cloud or obtained from the cloud through the WiFi module, and communication with mobile terminals such as mobile phones can be achieved through the WiFi module.
In an embodiment of the present invention, the refrigerator 100 includes a refrigerator food material management module 200, and the refrigerator food material management module 200 can automatically manage food material information in the refrigerator 100, for example, can obtain food material information such as a food material name and a food material storage duration stored in the refrigerator 100, and display the food material information through the display screen 102 or broadcast the food material information through the voice module, and of course, the food material information can also be transmitted to a mobile terminal such as a mobile phone through the WiFi module, so that a user can conveniently view the food material information in real time.
In the present embodiment, the refrigerator food management module 200 includes a tag 210 and a tag access device 220. The identifier 210 may be provided with a radio frequency tag 211, and the radio frequency tag 211 may be an RFID tag or an NFC tag. The identifier 210 may be a clip, to which the radio frequency tag 211 is attached, or may be just the radio frequency tag 211. The radio frequency reading module 230 may be disposed in the tag access device 220, the tag 210 may be disposed in the tag access device 220, the tag access device 220 may be mounted on the door body 101 of the refrigerator 100, specifically, may be mounted on the inner side of the refrigeration door body 101, so that a user may conveniently access the tag 210 during use. When a user wants to store food in the refrigerator 100, the identifier 210 may be taken out of the identifier accessing device 220, the identifier 210 may be attached to the food and stored in the refrigerator 100 together with the food, and when the user takes out the food from the refrigerator 100, the identifier 210 attached to the food may be taken down again into the identifier accessing device 220.
The food material management module may also include a control module 240 and a processing module 250. The control module 240 and the processing module 250 may be independent of the control module 240 and the processing module 250 of the refrigerator 100, or the control module 240 and the processing module 250 may be shared with the refrigerator 100, and the processing module 250 may be disposed at the cloud.
In this embodiment, the control module 240 may be configured to control the rf reading module 230 to read the rf tag 211 in the tag access device 220, and the processing module 250 may be configured to obtain the access status of the tag 210 and the food information associated with the tag 210 according to the tag information read by the rf reading module 230, and may manage the food storage list according to the access status of the tag 210. The food material storage list may be displayed on the display 102, and the food material information stored in the refrigerator 100 may be obtained through the food material storage list.
The radio frequency tags 211 may have encoded information stored therein, and each tag 211 may have a unique corresponding code. The refrigerator food material management module 200 may further include a storage module 260, where the storage module 260 may store codes of the identifier 210 and food material information corresponding to each code, where the food material information corresponding to each code is food material information associated with the identifier 210 corresponding to each code. Meanwhile, for convenience of use, the identifier 210 may be provided with text or graphic information to indicate the corresponding food material.
After receiving the code of the tag 211 read by the rf reading module 230, the processing module 250 may query the storage module 260 for whether the corresponding code exists and food information corresponding to the code, and then determine whether the food is stored in the refrigerator 100 according to the access state of the identifier 210. When the access state of the identification piece 210 in the identification access device 220 is changed, it can be considered that the food material stored in the refrigerator 100 is changed.
Of course, the storage module 260 may store only the preset code of the identifier 210, and when the radio frequency reading module 230 detects that the user takes out the identifier 210 from the identifier access device 220, if the storage module 260 does not store the food material information corresponding to the code corresponding to the identifier 210, a prompt may be sent by the display screen 102, the voice module or the mobile terminal such as a mobile phone, to prompt the user to autonomously input the food material information and store the food material information input by the user in the storage module 260. When it is detected that the user replaces the identifier 210 in the identifier accessing device 220, the food material information corresponding to the code of the identifier 210 in the storage module 260 may be deleted.
The code stored in the tag 211 may be a code carried by the radio frequency tag 211 during production and manufacture, or may be a code written later. To improve the transmission efficiency, short codes such as 01, 02, 03 may be written in the tag 211, which also facilitates management and mass production of the memory module 260.
Specifically, for example, the tag 211 having 5 identifiers 210,5 identifiers 210 stored in the identifier access device 220 may have codes 01, 02, 03, 04, and 05, and the storage module 260 may have food information corresponding to each code, such as 01-beef; 02-fish; 03-apple; 04-green vegetables; 05-milk. If the rf reading module 230 detects that the codes of the tag 211 placed in the tag accessing device 220 are 01, 03, and 04, the accessing status of the tag 210 corresponding to 01, 03, and 04 may be marked as the storing status, and the status of the tag 210 corresponding to 02, and 05 may be the retrieving status. That is, it may be considered that the user removes 02, 05 the corresponding identifier 210 and attaches it to the corresponding food material to store it in the refrigerator 100, and at this time, the fish and milk stored in the refrigerator 100 may be displayed in the food material storage list, for example, 02-fish and 05-milk may be displayed in a column of the stored food material on the display screen 102 of the refrigerator 100.
In an embodiment of the present invention, the processing module 250 is further configured to manage the food material storage list according to the final access status of the identifier 210 if the number of access status changes of the same identifier 210 within the first preset time period is detected to be greater than or equal to two.
In this embodiment, if the access state of the identifier 210 is detected for multiple times within the first preset time period, it may be determined that an abnormal situation may exist at this time, for example, the user may block the tag 211 of the other identifier 210 in the process of taking out or storing the tag from or into the identifier 210, so that the tag 211 is not recognized, or the door body 101 of the refrigerator 100 may shake or the tag access device 220 shakes during use, so that the tag 210 accessed in the tag access device 220 is jumped, so that the radio frequency reading module 230 cannot read the tag 211 of the tag 210, or the user may take out a part of food or view the food, so that the tag 211 attached to the food is misread. If the food material storage list is updated in real time according to the actual access state of the identifier 210, the accuracy of the corresponding food material information storage situation will be affected, and meanwhile, the stored information of the food material information corresponding to the same identifier 210 in the food material storage list may change continuously in a short time, and the corresponding information is jumped on the display screen 102 or repeatedly broadcasted through the voice module, which easily brings a fault impression to the user and affects the user experience.
Further, in an embodiment of the present invention, the control module 240 is specifically configured to: controlling the rf reading module 230 to read the rf tag 211 in the tag access device 220 at preset time intervals; the processing module 250 is configured to: and after receiving the tag information read by the radio frequency reading module 230 for a second preset time period, managing the food material storage list according to the access state of the identifier 210, wherein the first preset time period is greater than or equal to twice the preset time interval, and the second preset time period is greater than or equal to twice the preset time interval.
In this embodiment, the rf reading module 230 may include an antenna, and in order to improve the accuracy of the identification, the rf reading module 230 may include a dual antenna. The identification access device 220 may be a box body mounted on a door liner of the door body 101, the box body may extend along a width direction of the door body 101, the dual antennas may be respectively disposed at two ends of the box body, and scan the identification piece 210 in the identification access device 220 synchronously, and perform de-duplication processing after scanning, so as to remove codes corresponding to tags repeatedly scanned by the two antennas. During operation, the rf reading module 230 may remain continuously operating, and the antenna may be scanned sequentially from side to side, and the predetermined time interval may be the time required for the antenna to scan completely, i.e., once for the same identifier. Of course, the preset time interval may be the time interval between when the antenna completes one scan and when the antenna is started again, or the time interval between when the antenna is started twice.
The tag 211 information read by the rf reading module 230 may be transmitted to the processing module 250, and the processing module 250 may process the tag 211 information and display the tag 211 information on the display screen 102. The processing module 250 updates the food storage list after receiving the tag information read by the radio frequency reading module 230 for a second preset period of time, so that the radio frequency reading module 230 can read the tag 211 of the tag 210 in the tag access device 220 at least twice in the time between updating the food storage list and can process the tag information to obtain more accurate information, and simultaneously can ensure timeliness of updating the food storage list as much as possible.
Further, in an embodiment of the present invention, the processing module 250 is specifically configured to:
if the initial access state and the final access state of the identifier 210 are the same within the first preset time period, the food material information corresponding to the identifier 210 in the food material storage list is kept unchanged.
Specifically, for example, if the access state of the identifier with the tag code of 01 is detected to be the put-in state at time t1, the access state of the identifier with the tag code of 01 is detected to be the take-out state at time t2, and the access state of the identifier with the tag code of 01 is detected to be the store state at time t3, if the time interval from time t1 to time t3 is smaller than the first preset time period, and the access states of the identifiers 210 at time t1 and time t3 are the same, that is, the initial access state and the final access state of the identifiers 210 are the same within the first preset time period, it may be considered that the access state of the identifiers 210 is not changed within the first preset time period, and the food material information associated with the identifiers 210 in the food material storage list is not required to be updated.
Further, in an embodiment of the present invention, the processing module 250 is further configured to:
if the encoded information read by the rf reading module 230 is not queried in the storage module 260, the identifier 210 is marked as an abnormal identifier 210.
In the present embodiment, if a user puts another article with the rf tag 211 into the tag access device 220, disturbing information may be generated, which may cause a disorder in the food storage list. Therefore, when the encoded information read by the rf reading module 230 is not stored in the storage module 260, the identifier 210 may be directly marked as an abnormal identifier 210, for example, the indication may be performed through an interaction module such as the display screen 102, and meanwhile, the identifier 210 may be directly recorded in the storage module 260 as the abnormal identifier 210, and the food storage list is not updated according to the abnormal identifier.
Further, in an embodiment of the present invention, the processing module 250 is further configured to: if the code information read by the rf reading module 230 includes two or more identical code information, the identifier 210 corresponding to the two or more identical codes is marked as an abnormal identifier 210.
In this embodiment, in order to ensure the normal operation of the food material management module, the code in each identifier 210 is a single code different from the codes of other identifiers 210, so that different food materials can be distinguished by the codes. If the rf reading module 230 reads two identical encoded information, it may be that the identifier 210 on the other similar refrigerator 100 is placed into the identifier accessing device 220 by mistake, so in order to avoid confusion of food material information, two identifiers 210 with identical tag codes may be marked as abnormal identifiers 210.
Further, in an embodiment of the present invention, the processing module 250 is further configured to: when the access state of the tag 210 is changed from the stored state to the taken state, the taken time of the tag 210 is recorded.
In the present embodiment, the removal time may be recorded when the tag 210 is removed, and the removal time of the tag 210 may be determined as the time when the food corresponding to the tag 210 is stored in the refrigerator 100, and thus, the storage time of the corresponding food may be recorded according to the removal time of the tag 210. The storage module 260 may further store an optimal storage time period corresponding to the food material, and when the storage time of the food material is detected to reach the optimal storage time period, the storage module may control to send out a corresponding prompt. If the access state of the identifier 210 is detected to change twice or more in the first preset time period, and the initial access state and the final access state are both the removal states, the removal time corresponding to the identifier 210 is recorded according to the initial access state. Therefore, errors in recording of the corresponding food storage time caused by abnormal states can be avoided, and prompt cannot be timely carried out when the actual storage time of the food reaches the optimal storage time.
Further, in an embodiment of the present invention, the door opening/closing state detection module 103 may be further installed on the refrigeration door 101 of the refrigerator 100. The door opening and closing state detection module 103 may be used to detect the opening and closing state of the door 101, and the door opening and closing state detection module 103 may be a pressure sensor or a hall sensor or any other suitable sensor installed between the door 101 and the case. The control module 240 is configured to: when detecting that the door body 101 is in an open state, controlling the radio frequency reading module 230 to read the tag 211 in the tag access state device in real time; if the opening/closing state of the door body 101 is changed from the door opening state to the door closing state, the radio frequency reading module 230 is controlled to read the tag 211 in the tag storage device for a preset number of times, and then stop operation. Thus, reading the tag 211 information of the identifier 210 in real time when the door is opened can improve the timeliness of reading the tag 211 and the accuracy of identification by the radio frequency reading module 230; after the door is closed and the preset times are read in a delayed manner, the radio frequency reading module 230 stops running, so that the accuracy of identification of the identification piece 210 can be ensured, and the energy consumption can be reduced.
It should be understood that although the present disclosure describes embodiments in terms of examples, not every embodiment is provided with a single embodiment, and that this description is for clarity only, and that the skilled artisan should recognize that the embodiments may be combined appropriately to form other embodiments that will be understood by those skilled in the art.
The above list of detailed descriptions is only specific to practical embodiments of the present invention, and is not intended to limit the scope of the present invention, and all equivalent embodiments or modifications that do not depart from the spirit of the present invention should be included in the scope of the present invention.
