With the improvement of people's living standards, higher requirements are placed on the preservation effect of refrigerators. Theoretical studies have found that magnetic fields have a great influence on the low-temperature storage of food, because the magnetic field limits the free path of water molecules to a certain extent, so that the growth of crystal nuclei is inhibited, so that food is less likely to freeze at low temperatures, so that refrigeration can be achieved at a certain sub-zero temperature, or the ice crystals produced when the food is frozen can be reduced to reduce damage to the food cells. Therefore, applying a magnetic field to the food can play a good auxiliary role in the low-temperature storage of the food and improve the preservation effect of the food. Therefore, refrigerators are also actively exploring the introduction of magnetic fields into fresh-keeping storage to improve the preservation effect of refrigerators. Utility Model Content

[0043] Furthermore, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" 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 an indirect connection through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0044] like Figures 1 to 5 As shown, in one embodiment, the refrigerator includes a box body 100, a drawer 200 and a magnetic field device 300. The box body 100 is formed with a storage compartment 101. The drawer 200 is arranged in the storage compartment 101 for containing stored objects. The magnetic field device 300 includes a shell 310 and at least one magnetic field generating member 320, the shell 310 is formed with a receiving space, and the magnetic field generating member 320 is arranged in the receiving space. The magnetic field device 300 is arranged on the top of the drawer 200 to at least cover a portion of the top opening of the drawer 200.

[0045] Reference Figure 1 and Figure 2 As shown, specifically, the refrigerator further includes a door body (not marked in the figure), which is pivotally connected to the box body 100. The storage compartment 101 has an opening toward the front of the refrigerator, and the door body can be rotated relative to the box body 100 to open and close the front opening of the storage compartment 101. The drawer 200 is pullable and arranged in the storage compartment 101 for placing stored items.

[0046] When the user needs to take and place the stored object, the user can open the door body, and then extract the drawer 200 from the storage compartment 101 to realize the taking and placing of the stored object. After the storage object is taken and placed, the user can push the drawer 200 back to the storage compartment 101, and then close the door body.

[0047] Reference Figures 1 to 5 As shown, further, the magnetic field device 300 is a square plate-shaped structure as a whole. The outer shape of the shell 310 is a square plate-shaped structure, and the interior is hollow to form a storage space. The storage space can be an openable and closable space. The magnetic field generating member 320 is arranged in the storage space. When the drawer 200 is in a state of being retracted into the storage compartment 101, the magnetic field device 300 is located at the top of the drawer 200 and covers the top opening of the drawer 200, so that the magnetic field device 300 can generate a magnetic field in the internal space of the drawer 200.

[0048] Reference Figure 3 and Figure 4As shown, specifically, the housing 310 is connected to the drawer 200 in a relatively sliding manner, that is, the magnetic field device 300 as a whole is connected to the drawer 200 in a relatively sliding manner. Specifically, the housing 310 is connected to the left and right side panels of the drawer 200 in a sliding manner, and the housing 310 and the drawer 200 slide relatively along the front and rear direction of the drawer 200. Figure 5 As shown, in the process of taking and placing stored objects, after the drawer 200 is pulled out from the storage compartment 101, the magnetic field device 300 needs to be slid to expose the opening of the drawer 200, so as to achieve the taking and placing of stored objects.

[0049] It should be noted that, in some other embodiments, the magnetic field device may also be connected to the drawer in a relatively slidable manner along the left and right directions of the drawer. In addition, in some other embodiments, the magnetic field device may also be fixed to the top of the drawer, and when the stored items need to be taken out, the magnetic field device is removed from the drawer.

[0050] Reference Figures 3 to 5 As shown, specifically, the magnetic field generating element 320 is an electromagnetic coil, and the electromagnetic coil when energized can generate a magnetic field. The magnetic field can act on the stored objects placed in the drawer 200, so that the stored objects are stored under the action of the magnetic field, thereby improving the preservation effect.

[0051] It should be noted that, in some other embodiments, the magnetic field generating element may also be a permanent magnet sheet, or a structure composed of a permanent magnet sheet and an electromagnetic coil. Figure 6 As shown, the magnetic field generating element 320 includes an electromagnetic coil 321 and a permanent magnetic sheet 322. The electromagnetic coil 321 is attached to one side of the permanent magnetic sheet 322. The electromagnetic coil 321 and the permanent magnetic sheet 322 jointly generate a magnetic field.

[0052] It should be noted that electromagnetic coils may also be provided on both sides of the permanent magnet sheet.

[0053] like Figure 7 As shown, in some other embodiments, the magnetic field generating member 320 includes an electromagnetic coil 321 and a permanent magnet sheet 322, and the electromagnetic coil 321 surrounds the permanent magnet sheet 322. Specifically, the permanent magnet sheet 322 is arranged in the area surrounded by the electromagnetic coil 321, and the permanent magnet sheet 322 can be smaller than the area surrounded by the electromagnetic coil 321, or can be exactly equal, so that the electromagnetic coil 321 fits the side of the permanent magnet sheet 322.

[0054] Reference Figure 1 and Figure 2 As shown, further, the refrigerator also includes an evaporator 400 and a refrigeration fan 500. The evaporator 400 can release cold energy, and the refrigeration fan 500 can generate a refrigeration airflow carrying cold energy and make the refrigeration airflow flow to the storage compartment 101 to cool the storage compartment 101.

[0055] Continue to refer to Figure 1 and Figure 2 As shown, the storage compartment 101 has an air inlet 102, and the top side of the air inlet 102 is located higher than the magnetic field device 300, so that the cooling airflow entering the storage compartment 101 through the air inlet 102 can flow forward along the top of the magnetic field device 300, which is conducive to the full diffusion of the cooling airflow in the storage compartment 101.

[0056] In the solution of this embodiment, by setting the magnetic field device 300 at the top of the drawer 200, the magnetic field device 300 can generate a magnetic field in the internal space of the drawer 200, so that the stored objects placed in the drawer 200 are subjected to the magnetic field during the storage process to improve the preservation effect. The magnetic field device 300 is relatively close to the storage area of ​​the stored objects, that is, the internal space of the drawer 200, which is conducive to reducing the attenuation of the magnetic field, thereby helping to reduce the requirements of the magnetic field source and save costs. The magnetic field device 300 includes a shell 310 and a magnetic field generating member 320. The magnetic field generating member 320 is arranged in the accommodating space formed by the shell 310, so that the shell 310 can protect the magnetic field generating member 320, and the magnetic field device 300 can use the shell 310 to achieve connection with other components, thereby avoiding the modification of the shape and structure of the magnetic field generating member 320, which is conducive to ensuring the uniformity of the magnetic field of the magnetic field generating member 320, and is easy to install. In addition, the magnetic field device 300 covers the top of the drawer 200, so that the magnetic field device 300 and the drawer 200 together form a relatively closed space, reducing the situation where cold air blows directly onto the stored items in the drawer 200, which is beneficial to maintaining the temperature and humidity of the internal space of the drawer 200 stable and improving the preservation quality.

[0057] It should be noted that the box body is generally formed with multiple storage compartments, and the multiple storage compartments can be used to achieve different functions, such as a refrigeration compartment, a freezing compartment, a variable temperature compartment, etc. For the refrigerator of the present application, those skilled in the art can configure the number, function and layout of specific storage compartments according to needs. The magnetic field device and the drawer can be set in one storage compartment, or the magnetic field device and the drawer can be set in multiple storage compartments respectively.

[0058] In addition, it should be noted that, in the case where the refrigerator can have an ordinary storage compartment and a storage compartment equipped with a magnetic field device, the storage compartment of the refrigerator used to achieve magnetic field storage can use a separate refrigeration system, or it can share a refrigeration system with an ordinary refrigeration compartment, or it can also share a refrigeration system with an ordinary freezer compartment.

[0059] like Figure 3As shown, further, along the front-to-back direction of the drawer 200, the ratio of the length of the magnetic field generating member 320 to the length of the internal space of the drawer 200 is greater than or equal to 0.8 and less than or equal to 1.5. Specifically, the length of the magnetic field generating member 320 along the front-to-back direction of the drawer 200 is L1, and the length of the internal space of the drawer 200 along the front-to-back direction of the drawer 200 is L2, that is, the value of L1 / L2 is greater than or equal to 0.8 and less than or equal to 1.5. For example, it can be 0.8, 0.9, 1, 1.1, 1.2, 1.3, 1.4, 1.5, etc.

[0060] For example, the length of the inner space of the drawer 200 along the front-to-back direction of the drawer 200 is 30 cm, and the length of the magnetic field generating element 320 along the front-to-back direction of the drawer 200 can be 24 cm, or 30 cm, or 45 cm, etc. Through the above structure, it is helpful to ensure that the magnetic field generated by the magnetic field generating element 320 fully covers the inner space of the drawer 200 in the front-to-back direction, and the magnetic field strength is relatively uniform in the front-to-back direction, thereby ensuring the fresh-keeping effect.

[0061] like Figure 5 As shown, further, along the left-right direction of the drawer 200, the ratio of the width of the magnetic field generating member 320 to the width of the internal space of the drawer 200 is greater than or equal to 0.6 and less than or equal to 1.3. Specifically, the width of the magnetic field generating member 320 along the left-right direction of the drawer 200 is W1, and the width of the internal space of the drawer 200 along the left-right direction of the drawer 200 is W2, that is, the value of W1 / W2 is greater than or equal to 0.6 and less than or equal to 1.3. For example, it can be 0.6, 0.7, 0.8, 0.9, 1, 1.1, 1.2, 1.3, etc.

[0062] For example, the width of the inner space of the drawer 200 along the left-right direction of the drawer 200 is 40 cm, and the width of the magnetic field generating element 320 along the left-right direction of the drawer 200 can be 36 cm, or 40 cm, or 52 cm, etc. Through the above structure, it is helpful to ensure that the magnetic field generated by the magnetic field generating element 320 fully covers the inner space of the drawer 200 in the left-right direction, and the magnetic field strength is relatively uniform in the left-right direction, thereby ensuring the preservation effect.

[0063] like Figure 3 As shown, further, the ratio of the thickness of the magnetic field generating member 320 to the height of the inner space of the drawer 200 is greater than or equal to 0.005 and less than or equal to 0.2. Specifically, the thickness of the magnetic field generating member 320 is H1, and the height of the inner space of the drawer 200 is H2, that is, the value of H1 / H2 is greater than or equal to 0.005 and less than or equal to 0.2. For example, it can be 0.005, 0.008, 0.1, 0.12, 0.15, 0.2, etc.

[0064] For example, the height of the inner space of the drawer 200 is 20 cm, and the thickness of the magnetic field generating element 320 can be 1 mm, or 2 cm, or 4 cm, etc. Through the above structure, it is beneficial to make the magnetic field strength of the magnetic field generated by the magnetic field generating element 320 distributed more evenly in the height direction of the drawer 200.

[0065] like Figure 8 and Fig. 9 As shown, in one embodiment, the magnetic field device 300 includes a plurality of magnetic field generating members 320, and the plurality of magnetic field generating members 320 are arranged in parallel in the accommodation space. Specifically, the magnetic field device 300 includes two magnetic field generating members 320, and the magnetic field generating members 320 are electromagnetic coils. The two electromagnetic coils are arranged in parallel in the accommodation space of the housing 310 along the front-back direction of the drawer 200. By providing a plurality of magnetic field generating members 320, it is beneficial to make the magnetic field strength of the internal space of the drawer 200 more uniform.

[0066] It should be noted that, in some other embodiments, the number of magnetic field generating elements may be three or more. In addition, the magnetic field generating element may also be a permanent magnetic sheet, or a structure composed of an electromagnetic coil and a permanent magnetic sheet.

[0067] In addition, in some other embodiments, a plurality of magnetic field generating elements may also be arranged in parallel along the left and right directions of the drawer. Fig.10 and Fig.11 As shown, illustratively, the magnetic field device 300 includes two magnetic field generating elements 320 , and the two magnetic field generating elements 320 are arranged side by side in the accommodation space along the left-right direction of the drawer 200 .

[0068] It should be noted that, when the magnetic field device is provided with a plurality of magnetic field generating elements, the length or width of the magnetic field generating element is the sum of the lengths or widths of all the magnetic field generating elements.

[0069] like Figures 12 to 15 As shown, the magnetic field device 300 also includes a shim plate 330, which is arranged in the accommodation space, and a magnetic field generating element 320 is arranged on the side of the shim plate 330 facing the drawer 200. Specifically, the shim plate 330 is a plate-shaped structure, and the shim plate 330 is made of a magnetic conductive material, such as silicon steel material. The shim plate 330 and the magnetic field generating element 320 are arranged together in the accommodation space of the housing 310, and the magnetic field generating element 320 is arranged on the bottom side of the shim plate 330. The shim plate 330 can guide the magnetic field generated by the magnetic field generating element 320, thereby improving the uniformity of the magnetic field strength in the internal space of the drawer 200.

[0070] like Fig.15As shown, further, along the left-right direction of the drawer 200, the ratio of the width of the shim plate 330 to the width of the magnetic field generating member 320 is greater than or equal to 0.7 and less than or equal to 1.2. Specifically, the width of the shim plate 330 along the left-right direction of the drawer 200 is D1, and the width of the magnetic field generating member 320 along the left-right direction of the drawer 200 is D2, that is, the value of D1 / D2 is greater than or equal to 0.7 and less than or equal to 1.2. For example, it can be 0.7, 0.8, 0.9, 1, 1.1, 1.2, and so on.

[0071] For example, the width of the magnetic field generating member 320 along the left and right direction of the drawer 200 is 40 cm, and the width of the shim plate 330 along the left and right direction of the drawer 200 can be 28 cm, 40 cm or 48 cm, etc. The above structure is conducive to ensuring the guiding effect of the shim plate 330 on the magnetic field generating member 320.

[0072] It should be noted that, in some other embodiments, when a shimming plate is provided, the magnetic field device may also be provided with a plurality of magnetic field generating elements, and the plurality of magnetic field generating elements are jointly arranged on the side of the shimming plate facing the drawer. Fig.16 and Fig.17 As shown, the magnetic field device 300 includes a uniform magnetic plate 330 and two magnetic field generating elements 320. The two magnetic field generating elements 320 are arranged in parallel along the front-to-back direction of the drawer 200. The two magnetic field generating elements 320 are arranged on the side of the uniform magnetic plate 330 facing the drawer 200, that is, on the bottom side of the uniform magnetic plate 330.

[0073] Or, for example, Fig.18 and Fig.19 As shown, the magnetic field device 300 includes a uniform magnetic plate 330 and two magnetic field generating elements 320. The two magnetic field generating elements 320 are arranged in parallel along the left and right directions of the drawer 200. The two magnetic field generating elements 320 are arranged on the side of the uniform magnetic plate 330 facing the drawer 200, that is, on the bottom side of the uniform magnetic plate 330.

[0074] like Fig. 20 and Fig.21 As shown, in one embodiment, the refrigerator includes two brackets 600, which are respectively arranged on the left and right sides of the drawer 200, and the brackets 600 are used to support the magnetic field device 300 on the top of the drawer 200. The magnetic field device 300 includes a housing 310 and a magnetic field generating member 320, and the magnetic field generating member 320 is an electromagnetic coil.

[0075] Specifically, the height of the bracket 600 is higher than the height of the drawer 200, and the magnetic field device 300 is arranged on the top of the bracket 600 and supported by two brackets 600 on the top of the drawer 200. It should be noted that the matching mode between the magnetic field device 300 and the bracket 600 can be a simple placement or a detachable fixed structure or a non-detachable fixed structure. For example, the bracket may have a groove that matches the shape of the magnetic field device, and the magnetic field device is prevented from being in the groove; or a socket may be set in one of the shell of the magnetic field device and the bracket, and a plug rod may be set in the other, and the plug rod is embedded in the socket to achieve the matching of the two; or the shell of the magnetic field device and the bracket are fixed by screws; or the shell of the magnetic field device and the bracket are ultrasonically welded together. The magnetic field device 300 is stable on the top of the bracket 600, and will not interfere with the pulling and pulling activities of the drawer 200, so that the drawer 200 can move freely. It should be noted that the form of the bracket 600 can be a rod, a plate, and other forms.

[0076] By using the bracket 600 to support the magnetic field device 300, the magnetic field device 300 is located on the top of the drawer 200 in the retracted state, so that the magnetic field device 300 does not need to move with the drawer 200, thereby making it more convenient to take and put stored objects in the drawer 200.

[0077] like Fig. 20 and Fig.21 As shown, further, the distance between the bottom surface of the magnetic field device 300 and the top opening of the drawer 200 is greater than or equal to 2 mm and less than or equal to 15 mm. Specifically, the distance between the bottom surface of the magnetic field device 300 and the top opening of the drawer 200 is t, and the value of t is greater than or equal to 2 mm and less than or equal to 15 mm. For example, it can be 2 mm, 3 mm, 5 mm, 7.5 mm, 9 mm, 10 mm, 13 mm or 15 mm, etc. The above structure helps to avoid the drawer 200 from bumping against the magnetic field device 300 when it is active, and at the same time ensures that the magnetic field generated by the magnetic field device 300 in the internal space of the drawer 200 has a better effect.

[0078] It should be noted that, in some other embodiments, when a bracket is provided, the magnetic field device may also include a plurality of magnetic field generating elements, and the specific structure is as described above (eg Fig. 9 and Fig.11 Alternatively, in the case of providing a bracket, the magnetic field device may also include a shim plate, and the specific structure is as described above (as shown in Fig.13 and Fig.15 Alternatively, in the case of providing a bracket, the magnetic field device may also include a shim plate and a plurality of magnetic field generating components, and the specific structure is as described above (such as Fig.17 and Fig.19 (shown)

[0079] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived from the contents disclosed in the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
