[0026] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0028] For example, if the device in the figures is turned over, elements described as "below" or "beneath" other elements or features would then be oriented "above" the other elements or features. Thus, the exemplary term "below" can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

[0029] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0030] It should be noted that the term "comprising" or any other variation thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In addition, the terms "first", "second", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0031] An embodiment of the present invention provides a food storage device 100. The storage device 100 refers to a device or container specifically used to store, preserve and manage food. These devices can ensure that the food remains fresh, nutritious and tasty during storage. The storage device 100 can be a refrigerator, a freezer, or a module in a refrigerator or a freezer, such as a fresh-keeping drawer.

[0032] As shown in Fig. 1(a) and Fig. 1(b), in one embodiment, the storage device 100 comprises a first box cover 1 and a first box body 2, the first box body 2 comprises an opening, and the first box cover 1 is arranged at the opening. The first box cover 1 and the first box body 2 can be combined by snap connection, thread connection, magnet connection or other connection methods to form a closed space for storing food.

[0033] In a specific embodiment, continuing to refer to Figures 1(a) and 1(b), the first box cover 1 includes a first cover plate 3, which is arranged on one side of the first box cover 1 facing the opening of the first box body 2, and a first electromagnetic coil 7 is arranged between the first box cover 1 and the other side of the first cover plate 3.

[0034] In other embodiments, the storage device 100 may also be a closed storage space, and a first electromagnetic coil 7 is disposed on a side wall of the storage space. There is no specific limitation on the structural design of the storage device 100.

[0035] The storage device 100 includes a first component 11 for generating a magnetic field. On the one hand, the magnetic field is used to keep the food in the storage device 100 fresh. On the other hand, the magnetic field indirectly affects the recognition function of the recognition component 13 by affecting the second component 12.

[0036] It should be noted that the effect of magnetic field on food preservation is mainly reflected in the fact that magnetic field can inhibit the growth of microorganisms and molds, thereby extending the storage period of food. Specifically, when using magnetic field to assist in the storage of food, the magnetic field limits the free path of water molecules to a certain extent, which is specifically manifested as the breaking of hydrogen bonds in the water molecule family, so that the growth of water crystal nuclei is inhibited during the phase change process, and the growth rate of ice crystals is higher than the migration rate of water molecules. The resulting ice crystals are smaller, resulting in less damage to cells, reducing the loss rate of juice in food, and allowing the nutrition and taste of food to be better preserved. Therefore, magnetic field can be used to assist in the storage of food, thereby achieving the purpose of extending the storage period of food.

[0037] As shown in FIG. 2(a) and FIG. 2(b), in one embodiment, the first component 11 includes a base 4 and a plurality of second cover plates 5, and a second electromagnetic coil 6 is disposed between the base 4 and the corresponding second cover plates 5. In this embodiment, the second cover plate 5 can fix the second electromagnetic coil 6 on the base 4 to prevent it from jumping, so as to avoid the position of the second electromagnetic coil 6 changing and causing uneven magnetic field distribution, thereby affecting the preservation effect or detection accuracy of the food. Through the design of multiple second cover plates 5, the second cover plates 5 can be flexibly installed or removed according to different storage conditions or requirements, thereby adjusting the number and layout of the second electromagnetic coils 6.

[0038] In the above embodiment, all the second electromagnetic coils 6 in the first component 11 are connected in parallel to the power supply of the storage device 100. By connecting the power supply in parallel, each second electromagnetic coil 6 can be powered independently, thereby generating its own magnetic field, which can form a uniformly distributed magnetic field area under the joint action of the base 4 and the second cover 5. In addition, parallel connection also means that each second electromagnetic coil 6 can be controlled independently, that is, the power supply of each second electromagnetic coil 6 can be adjusted as needed, thereby controlling the strength and distribution of the magnetic field, which is highly flexible and can more accurately adapt to different types of food or storage needs.

[0039] In another embodiment, the first component 11 may further include a base 4 and a second cover plate 5, and a plurality of second electromagnetic coils 6 are arranged between the base 4 and the second cover plate 5 according to preset position distribution. In this embodiment, by reducing the number of second cover plates 5, the structure of the first component 11 can be simplified, and the manufacturing cost and complexity can be reduced.

[0040] In other embodiments, the first component 11 may further include a base 4 and a second cover plate 5, and the base 4 and the second cover plate 5 are provided with a second electromagnetic coil 6. In this embodiment, the magnetic field generated by the second electromagnetic coil 6 is sufficient to cover a plurality of storage units.

[0041] The storage device 100 includes a second component 12, which is arranged within the range of the magnetic field generated by the first component 11. The second component 12 includes a first electromagnetic coil 7 and a storage unit, wherein the storage unit is used to place food, and the first electromagnetic coil 7 is arranged at the storage unit.

[0042] The storage device 100 includes an identification component 13 , a first end of the identification component 13 is connected to a first end of the first electromagnetic coil 7 , and a second end of the identification component 13 is connected to a second end of the first electromagnetic coil 7 .

[0043] Based on this, when the first component 11 is powered on, the first component 11 will generate a magnetic field, which will cover and pass through the closed loop formed by the first electromagnetic coil 1 in the second component 12 and the identification component 13 connected thereto. Based on Faraday's law of electromagnetic induction, when the magnetic flux passing through the closed loop changes, an induced electromotive force is generated in the first electromagnetic coil 7, and the induced electromotive force drives the free electrons in the closed loop to move, thereby forming an induced current between the identification component 13 and the first electromagnetic coil 7.

[0044] In a specific embodiment, an on-off switch can be provided in the closed loop formed by the interconnection of the first electromagnetic coil 7 and the identification component 13. When the on-off switch is closed, the circuit between the first electromagnetic coil 7 and the identification component 13 is complete, and normal electromagnetic induction and identification operations of the identification component can be performed.

[0045] In a specific embodiment, the circuit between the first electromagnetic coil 7 and the identification component 13 is always complete. As long as the first component 11 is powered on, the second electromagnetic coil 6 will continue to generate a magnetic field, and the identification component 13 will continue to monitor the change information of the food in the storage device 100.

[0046] The change of the food at the storage unit is detected to determine the change of the magnetic flux in the closed loop formed by the first electromagnetic coil 7 and the identification component 13. When the area covered by the food at the storage unit becomes larger, it is determined that the magnetic flux passing through the closed loop increases; when the area covered by the food at the storage unit becomes smaller, it is determined that the magnetic flux passing through the closed loop decreases.

[0047] Specifically, in one embodiment, when the food changes at the storage unit, the identification component 13 obtains the induced current and identifies the change information of the food. In this embodiment, the change of food may refer to the food volume becoming smaller (such as the water in the food evaporates and shrivels), and the magnetic flux in the corresponding closed loop becomes smaller; when the food volume becomes larger (such as the food becomes moldy and expands, etc.), the magnetic flux in the corresponding closed loop becomes larger.

[0048] It can be seen that by changing the volume or area of ​​the food placed on the storage unit, the influence of the closed loop in the magnetic field can be changed, thereby achieving control of the magnetic flux and the induced current. Specifically, when the food is placed on the storage unit, the "cutting" area corresponding to the closed loop in the magnetic field is determined according to the spatial volume of the storage unit occupied by the food. When the spatial volume of the food changes, the "cutting" area will also change accordingly, causing the magnetic flux passing through the closed loop to change.

[0049] In one embodiment, when the intensity of the magnetic field generated by the first component 11 changes, the identification component 13 obtains the induced current and identifies the change information of the food.

[0050] Specifically, by changing the magnitude of the current flowing to the first component 11, the change in the corresponding magnetic field strength is controlled. The greater the current, the stronger the magnetic field strength; the smaller the current, the weaker the magnetic field strength. When the magnetic field strength changes, the magnetic flux passing through the closed loop will also change accordingly.

[0051] In a specific embodiment, the storage unit can be placed close to the closed loop. In this embodiment, there is no gap between the storage unit and the closed loop, and the magnetic field can act more directly on the items placed in the storage unit, thereby achieving a better preservation effect.

[0052] In another specific embodiment, the storage unit can also be arranged at a preset distance above the closed loop. By maintaining a certain distance, direct physical contact between the storage unit and the electromagnetic coil can be reduced, thereby avoiding possible electromagnetic interference or physical damage.

[0053] In a specific embodiment, the identification component 13 may be a radio frequency identification component, such as RFID (Radio Frequency Identification). The signal receiving end of the RFID is installed on the refrigerator to receive information sent by the RFID.

[0054] like Figure 3 As shown, in one embodiment, the identification component 13 is integrated into a circuit control unit 8, based on which the first end of the circuit control unit 8 is connected to the first end of the first electromagnetic coil 7, and the second end of the circuit control unit 8 is connected to the second end of the first electromagnetic coil 7 to form a closed loop 14. In this embodiment, the circuit control unit 8 can not only capture and collect the induced current, but also improve the system integration and reliability of the entire storage device.

[0055] Continue to refer to Figure 3As shown, the second component 12 also includes a plurality of slots, and the first electromagnetic coil 7 is disposed in the slots for fixing the position distribution of the first electromagnetic coil 7. The slots shown in the figure are segmented, and there are three segments of slots, namely the first slot 9-1, the second slot 9-2 and the third slot 9-3. Each segment of the slot is an independent unit, which can be added, removed or rearranged as needed, and has strong flexibility and high adaptability.

[0056] certainly, Figure 3 The segmented slots 9-1, 9-2 and 9-3 shown in the figure can also be integrated, that is, several segmented slots are connected to form an integral body. Figure 3 The first end of the first card slot 9-1 is connected to the first end of the circuit control unit 8, the second end of the first card slot 9-1 is connected to the first end of the second card slot 9-2, the second end of the second card slot 9-2 is connected to the first end of the third card slot 9-3, and the second end of the third card slot 9-3 is connected to the second end of the circuit control unit 8 to form a "U"-shaped card slot. The first electromagnetic coil 7 is completely arranged in the card slot, and this design structure is stable and easy to assemble.

[0057] In a specific embodiment, the second component 12 includes the same number of storage units as the second cover plate 5. Figure 4 and Figure 6 As shown, for example, the storage device 100 can be a fresh-keeping drawer 20, which can be installed on the refrigerator liner through a slide rail or a slideway and can be pulled out horizontally. A number of fresh-keeping boxes 21 can be placed in the fresh-keeping drawer 20, and each fresh-keeping box 21 can be understood as a storage unit. The storage unit includes a second box cover and a second box body with an opening. The second box cover is arranged at the opening of the second box body to close or open the storage space. A closed loop formed by the first electromagnetic coil 7 and the identification component 13 connected to each other is arranged in the storage unit. Specifically, it can be arranged at the bottom of the second box body, or it can be arranged at the second box cover, so that the magnetic field generated by the first component 11 can pass through the closed loop, and there is no specific limitation on this.

[0058] like Figure 5 As shown, in a specific embodiment, the closed loop 14 can be installed in the third box cover 10 through the third cover plate 15. In this embodiment, the identification component 13 and the first electromagnetic coil 7 are arranged above the food through the closed loop 14. When the third box cover 10 is closed, the closed loop 14 and the food are separated by the third cover plate 15. This arrangement is more suitable for detecting changes on the surface or shallow layer of the food, such as evaporation of water on the surface of the food, mildew, etc.

[0059] In a specific embodiment, the closed loop can be installed in the third box body through the third cover plate. In this embodiment, the identification component 13 is arranged below or at the bottom of the food through the closed loop, and this arrangement is more suitable for detecting changes in the interior or deep layer of the food.

[0060] Understandably, if the first component 11 and the second component 12 are too close, the magnetic field generated by the first component 11 may be too concentrated and fail to evenly cover the entire storage device 100. Therefore, maintaining a certain distance can ensure that the magnetic field can evenly act on the food in the storage area.

[0061] In one embodiment, the first component 11 is arranged at a corresponding position above each fresh-keeping box, that is, the first component 11 is arranged above the second component 12, and the first component 11 and the second component 12 have a preset distance in the vertical direction. In this way, such interference can be effectively reduced to ensure that both components can work normally.

[0062] In this embodiment, the first component 11 can be arranged directly above the second component 12 (eg Figure 5 As shown), there may also be a certain deviation angle, as long as the second component 12 is within the magnetic field generated by the first component 11.

[0063] like Figure 6 As shown, for example, when one or some food preservation boxes 21 are used, they are placed in the refrigerator's fresh-keeping drawer 20, and are preferably used near the back corner of the fresh-keeping drawer 20. This allows for more efficient use of space, and even if multiple food preservation boxes 21 are placed in the drawer, a better spatial layout and ease of use can be maintained.

[0064] In addition, each food preservation box 21 will match or align with the second electromagnetic coil 7 at the corresponding position of the first component 11, for example, in combination with Figure 4 and Figure 6 As shown, a first component 11 is provided at a corresponding position above each fresh-keeping box. Figure 6 The three crisper boxes shown in Figure 4 There are three sub-areas A7, A8 and A9 in the first component 11, and two rows of storage units are distributed inside the fresh-keeping drawer 20. Each row of storage units includes three fresh-keeping boxes 21. Arranged from inside to outside and from left to right, the three fresh-keeping boxes 21 in the first row correspond to the three sub-areas A1, A2 and A3 in the first component 11, and the three fresh-keeping boxes 21 in the second row correspond to the three sub-areas A4, A5 and A6 in the first component 11. If the food fresh-keeping box 21 is not in use, it is placed elsewhere inside the refrigerator.

[0065] When storing food, the user stores different food in different food preservation boxes 21, and sequentially installs them into the fresh-keeping drawer 20. Since multiple first electromagnetic coils 6 can be provided on the base 4 of the first component 11, the placement positions of the food preservation boxes 21 are also different. After the user puts all the food preservation boxes 21 into the fresh-keeping area, the refrigerator control end energizes the electromagnetic coils in the A1, A2, A3, ..., A9 areas in turn, and generates a uniform magnetic field B, where B is the magnetic field strength generated after the first component 11 is energized.

[0066] Since the food preservation box 21 is placed in the closed loop formed by the second component 12 and the identification component 13, within a certain period of time, when the magnetic field strength changes from 0 to B or the food in the food preservation box 21 changes, the magnetic flux passing through the inside of the food preservation box 21 is Φ=B*S, wherein S is the area of ​​the closed loop inside the food preservation box 21, and the change in magnetic flux causes the closed loop to generate an induced current, driving the RFID module (i.e., the identification component 13) in the food preservation box 21 to respond and transmit the information to the refrigerator end.

[0067] The refrigerator receives RFID response information from at least one food preservation box 21 in the A1-A9 area. On the one hand, it can identify the change information of the food in the corresponding food preservation box 21, which includes but is not limited to the type, quantity, taking out or putting in of food, and shelf life of the food. On the other hand, it can generate a location distribution map of the food preservation box 21 according to the response of the RFID module in each area. The map shows the specific location of the food preservation box 211 inside the refrigerator, which is convenient for quickly finding the required food through the control interface.

[0068] Specifically, when the user is ready to take the food, he selects the type of food through the refrigerator. At this time, the location distribution information of the corresponding food preservation box 21 will also be fed back to the user, informing the user which area of ​​the A1-A9 area the food to be selected is stored in, so that the user can take it accurately.

[0069] In addition, the RFID module will also feed back the identified information to the refrigerator side while responding, for example, recording the number of times the food is accessed and / or the remaining amount of food in the fresh-keeping box. At the refrigerator side, the user can also enter the food information through the front display screen and write it to the RFID to update the food information in the food fresh-keeping box 21.

[0070] Every time the user takes out and puts in food, the refrigerator is closed and the refrigerator end will energize the second electromagnetic coils 7 in the A1-A9 areas in turn to determine whether the food preservation boxes 21 in each area exist; when the food preservation boxes 21 change their positions and the second electromagnetic coils 7 in the A1-A9 areas at the refrigerator end are energized, the identification components 13 at the corresponding positions respond, and feed back the information that has been read and written to the refrigerator end, and update the food change information in the food preservation boxes 21, so that the user can understand the changes in the food in real time.

[0071] An embodiment of the present invention provides a refrigerator, wherein a storage device is disposed in the refrigerator compartment.

[0072] In one embodiment, the storage device may adopt any of the embodiments or devices described in the specific embodiments described above.

[0073] like Figure 7 As shown, a food storage method is provided in one embodiment of the present invention.

[0074] The food storage method can be used to identify change information of food in a storage device.

[0075] In one embodiment, the storage device can be configured as described above, and the corresponding technical solution is configured and referenced in the food storage method provided in the present invention.

[0076] like Figure 7 As shown, in one embodiment of the present invention, a food storage method is provided, comprising the following steps.

[0077] Step S1, energizing the first component, and obtaining an induced current flowing in the first electromagnetic coil when the food material changes or the magnetic field strength changes at the storage unit;

[0078] Step S2, the induced current flows into and activates the identification component, and the identification component records and identifies the change information of the food in the storage device.

[0079] In this way, by setting the storage unit at the closed loop formed by the second component and the identification component, after placing the storage unit into the magnetic field formed by the first component, the user can quickly understand the change information of the food.

[0080] One embodiment of the present invention provides a computer-readable storage medium.

[0081] In one embodiment, a computer readable storage medium stores a computer program executed by the processor mentioned above, or a food storage method in any of the technical solutions mentioned above.

[0082] When the processor executes the computer program, it can execute the description of the food storage method in any of the above technical solutions, so it will not be repeated here. In addition, the description of the beneficial effects of the same method will not be repeated.

[0083] The computer-readable storage medium may include: a flash drive, a read-only memory (ROM), a random access memory (RAM), a magnetic disk or an optical disk, etc.

[0084] In summary, the present invention provides a food storage device and a storage method thereof. The device uses the magnetic field generated by the first component to activate the closed loop formed by the identification component and the first electromagnetic coil in the second component, thereby generating an induced current in the first electromagnetic coil. This induced current is captured by the identification component and used to analyze the detailed information of the food in the storage device. This process does not require human intervention, and realizes the instant capture and intelligent processing of food information, so that users can grasp the type, quantity and status of the food in the storage device at any time, improve the comprehensiveness and flexibility of food freshness management, improve the user experience, and enable users to more conveniently obtain food information, monitor food status and perform inventory management.
