Description

Technical Field

[0001] This invention relates to refrigeration and freezing equipment, and more particularly to a magnetic field preservation storage container and refrigerator. Background Technology

[0002] Consumers are increasingly concerned about the preservation effect of refrigerators. For foods like meat, fish, and shrimp, juice loss during storage can lead to a decline in taste and a darkening of color. This is especially true for certain high-end foods, whose quality can significantly decrease after a period of storage.

[0003] To improve the quality of stored goods, numerous improvement solutions have emerged in existing technologies. These include methods such as quick-freezing to increase the freezing speed of food or introducing food into a supercooled state. However, these solutions require increased refrigeration capacity and also lead to increased energy consumption. Therefore, more efficiently improving the quality of frozen storage has become a pressing technical challenge for refrigerator developers.

[0004] Theoretical studies have found that magnetic fields have a significant impact on the formation of ice crystals during the freezing process. The refrigeration industry has also actively explored the introduction of magnetic fields into food preservation; however, in practical applications within refrigerators, the effect of magnetic field-assisted preservation is not satisfactory. Summary of the Invention

[0005] One object of the present invention is to provide a magnetic field preservation storage container and refrigerator that effectively improves the quality of stored goods.

[0006] A further objective of this invention is to reduce component costs and facilitate the installation and application of magnetic field preservation storage containers in refrigerators.

[0007] Specifically, the present invention provides a magnetic field preservation storage container, comprising:

[0008] A storage component, which defines a storage space for placing stored items;

[0009] A magnet assembly includes a first magnet component and a second magnet component respectively disposed on a set of opposite sides of the storage assembly, and uses the first magnet component and the second magnet component to form a magnetic field in the storage space;

[0010] A magnetically conductive assembly has a first magnetically conductive element corresponding to a first magnet component, a second magnetically conductive element corresponding to a second magnet component, and a magnetically conductive connector connecting the first magnetically conductive element and the second magnetically conductive element. The first magnetically conductive element, the second magnetically conductive element, and the magnetically conductive connector form an annular magnetically conductive path outside the storage space.

[0011] Optionally, the first magnet component and the second magnet component each include: a permanent magnet plate disposed on the outer side of the corresponding side of the storage component, and the shape of the permanent magnet plate is consistent with the shape of its corresponding side.

[0012] The first magnetic conductive element and the second magnetic conductive element each include a magnetic conductive plate, which are respectively disposed opposite to the permanent magnet plate, and a magnetic conductive connector extends from the edge of the magnetic conductive plate along the outside of the storage assembly and connects to the magnetic conductive plate on the other side.

[0013] Optionally, the projection of the storage space onto the plane of the magnetic plate lies within the range of the magnetic plate, and the size of the permanent magnet plate is smaller than or equal to that of its counterpart magnetic plate.

[0014] Optionally, the first magnet component and the second magnet component further include an electromagnetic ring, which is disposed between the permanent magnet plate and the magnetic conductive plate or between the permanent magnet plate and the corresponding side of the storage component. An electromagnetic coil is wound around the inside of the electromagnetic ring along the circumferential direction. When the electromagnetic coil is energized, it is used to generate an electromagnetic field that is superimposed on the permanent magnet magnetic field of the corresponding permanent magnet plate.

[0015] Optionally, the size of the electromagnetic ring is less than or equal to the size of its relative permanent magnet plate, and the centers of the permanent magnet plate, the magnetic conductive plate, and the electromagnetic ring of the first magnet component are opposite each other, and the centers of the permanent magnet plate, the magnetic conductive plate, and the electromagnetic ring of the second magnet component are opposite each other.

[0016] Optionally, the first magnet component is disposed on the top wall of the storage assembly, and the second magnet component is disposed on the bottom wall of the storage assembly, and the first magnet component and the second magnet component are substantially the same size.

[0017] Optionally, the magnetic field directions of the first magnet component and the second magnet component are set to be the same, so that the magnetic field direction in the storage space is from top to bottom or from bottom to top.

[0018] Optionally, the magnetic connector includes:

[0019] The first connecting section extends from the middle of one side of the first magnet component along one side wall of the storage space to the middle of the corresponding side of the first magnet component.

[0020] The second connecting section extends from the middle of the other side of the first magnet component along the other side wall of the storage space to the middle of the other side of the first magnet component, and

[0021] The width of the first and second connecting sections along the front-to-back depth direction is one-quarter to one-tenth of the length of the magnetically conductive assembly along the front-to-back depth direction.

[0022] Optionally, the storage components include:

[0023] The cylindrical body has a forward opening; and

[0024] The drawers are pull-out and installed inside the cylinder, forming storage space.

[0025] According to another aspect of the present invention, a refrigerator is provided, comprising:

[0026] The container has a defined storage compartment inside;

[0027] Any of the above-mentioned magnetic field preservation storage containers are installed inside the storage room.

[0028] The magnetic field preservation storage container of the present invention utilizes a magnetic component to generate a magnetic field within the storage space. This magnetic field helps improve storage quality, shortens freezing time, reduces juice and nutrient loss, lowers the number of microorganisms and bacteria, and extends the shelf life. The magnetic guiding component uses a first magnetic guiding element, a second magnetic guiding element, and a magnetic guiding connector to form a ring-shaped magnetic guiding path outside the storage space, thereby creating a uniform magnetic field within the storage space with sufficient strength to meet storage quality requirements.

[0029] Furthermore, in the magnetic field preservation storage container of the present invention, the first magnet component and the second magnet component are respectively provided with permanent magnet plates, and the permanent magnet magnetic field of the permanent magnet plates is used as the basic magnetic field of the storage space. The magnetic conductive plate is set against the permanent magnet plate to concentrate the magnetic field of the permanent magnet plate, which can prevent the magnetic field of the permanent magnet plate from leaking outward, enhance the magnetic flux density of the storage space, and improve the magnetic field utilization efficiency.

[0030] Furthermore, the magnetic field preservation storage container of the present invention may also be equipped with an electromagnetic ring. When the electromagnetic coil wound within the electromagnetic ring is energized, it generates an electromagnetic field that superimposes on the permanent magnet magnetic field of the corresponding permanent magnet plate. By utilizing the coordination of the electromagnetic field and the permanent magnet magnetic field, on the one hand, the magnetic flux density within the storage space is enhanced, resulting in a more uniform magnetic field distribution, which is beneficial for better food preservation; on the other hand, the ease of adjustment of the electromagnetic field allows for the coordination and adjustment of various magnetic fields to meet the storage requirements of different stored items.

[0031] Furthermore, the magnetic field preservation storage container of the present invention, through improvements to the construction of the magnet component and the magnetic conductive component, makes the magnetic field preservation storage container structure more compact, and is especially suitable for storage boxes and storage drawers, achieving magnetic field preservation in a relatively flat storage space.

[0032] Furthermore, the refrigerator of the present invention is equipped with the aforementioned magnetic field preservation storage container, which allows food to be stored in a magnetic field environment, inhibiting the growth of ice crystal nuclei. The growth rate of ice crystals is higher than the migration rate of water molecules, resulting in smaller ice crystals, thereby reducing damage to cells, preventing juice loss, ensuring better taste of food, improving the quality of frozen storage, and meeting users' requirements for the storage quality of precious food.

[0033] Furthermore, the refrigerator of this invention improves the quality of stored items through a magnetic field, providing a new preservation function for smart refrigerators, meeting users' increasingly higher demands for smart refrigerators, and further satisfying users' quality requirements for smart homes and smart living.

[0049] Figure 14 This is a control system block diagram of a refrigerator with a magnetic field-preserved storage container according to an embodiment of the present invention. Detailed Implementation

[0050] Figure 1 This is a schematic perspective view of a refrigerator 10 with a magnetic field preservation storage container 200 according to an embodiment of the present invention. The refrigerator 10 of this embodiment generally includes a cabinet 120, a door 110, and a refrigeration system (not shown). The cabinet 120 may define at least one front-opening storage compartment, and typically multiple compartments, such as a refrigerated storage compartment, a frozen storage compartment, a variable temperature storage compartment, etc. The specific number and function of the storage compartments can be configured according to pre-defined needs.

[0051] The refrigerator 10 in this embodiment can be a frost-free refrigerator. An air duct system is provided within the cabinet 120. A fan uses a fan to deliver the cooled airflow, which has undergone heat exchange in the heat exchanger (evaporator), to the storage compartment through the air inlet, and then returns it to the air duct through the air outlet. This achieves cooling. Since the cabinet 120, door 110, and refrigeration system of this type of refrigerator are all known and easily implemented by those skilled in the art, in order not to obscure or obscure the inventive points of this application, the cabinet 120, door 110, and refrigeration system themselves will not be described in detail below.

[0052] One or more storage compartments of the refrigerator 10 may be equipped with magnetic field preservation containers 200. When placed in the freezer compartment, the magnetic field preservation containers 200 can be used to freeze and preserve frozen food, inhibiting the growth of ice crystal nuclei, making the ice crystal growth rate higher than the water molecule migration rate, resulting in smaller ice crystals, thereby reducing damage to cells, preventing juice loss, accelerating the freezing process, and shortening the freezing time. When placed in the refrigerator compartment, the magnetic field preservation containers 200 can slow down the oxidation-reduction reaction of food, reduce nutrient and moisture loss, prevent food discoloration, inhibit bacterial growth, and extend the shelf life of food. The magnetic field preservation containers 200 can be arranged in the refrigerator compartment, freezer compartment, and variable temperature compartment for magnetic field-assisted preservation in these compartments, or they can be used as an independent compartment of the refrigerator 10.

[0053] The number of magnetic field preservation storage containers 200 and their arrangement in storage compartments can be configured according to user needs. For example, one or more magnetic field preservation storage containers 200 can be installed inside the refrigerator 10.

[0054] A magnetic field preservation storage container 200 generally includes: a storage component 210, a magnet component 220, and a magnetically conductive component 230. The storage component 210 defines a storage space for placing stored items, and the storage component 210 can be box-shaped. In some embodiments, the storage component 210 can be a flat rectangular parallelepiped shape (i.e., the distance along the height direction is significantly smaller than the distance along the depth direction and the distance along the left and right sides). The storage component 210 can be a drawer structure, that is, the storage component 210 can include: a cylindrical body and a drawer. The cylindrical body has a front opening. The drawer is pull-out disposed within the cylindrical body. When the drawer is pulled out, the storage space is exposed for retrieving and placing stored items. When the drawer is pushed back into the cylindrical body, it forms an independent sealed space.

[0055] Figure 2 This is a schematic diagram of a magnetic field preservation storage container 200 according to an embodiment of the present invention; Figure 3 yes Figure 2 Exploded view of the components of the magnetic field preservation storage container 200 shown; Figure 4 yes Figure 2 The diagram shows the cooperation between the magnet assembly 220 and the magnetic conductive assembly 230 in the magnetic field preservation storage container 200.

[0056] The magnet assembly 220 serves as the source of the magnetic field. The magnet assembly 220 may include a first magnet component 221 and a second magnet component 222 respectively disposed on a set of opposite sides of the storage assembly 210, and utilizes the first magnet component 221 and the second magnet component 222 to form a magnetic field in the storage space. The opposite sides where the first magnet component 221 and the second magnet component 222 are located can be selected according to the shape of the storage assembly 210 and its position within the refrigerator 10; for example, they can be placed on the horizontal sides, top and bottom sides, or front and back sides of the storage assembly 210. The magnetic poles of the first magnet component 221 and the second magnet component 222 both face towards the storage space.

[0057] When the storage component 210 is generally flat, especially when it is a drawer, the first magnet component 221 and the second magnet component 222 can preferably be arranged on the top and bottom sides of the storage component 210. The first magnet component 221 is located on the top wall of the storage component 210, and the second magnet component 222 is located on the bottom wall of the storage component 210, with the magnetic field penetrating the storage space from top to bottom or from bottom to top. This arrangement reduces the distance between the first magnet component 221 and the second magnet component 222, improving the strength and uniformity of the magnetic field.

[0058] The first magnet component 221 and the second magnet component 222 may have substantially the same structure and size, and their positions can be set according to the structure of their respective side surfaces. Generally, the first magnet component 221 and the second magnet component 222 are opposite to the center of their respective side surfaces.

[0059] The first magnet component 221 and the second magnet component 222 may each include a permanent magnet plate. The permanent magnet plate is disposed on the outer side of the corresponding side of the storage component 210, and the shape of the permanent magnet plate is consistent with the shape of its corresponding side. For example, when the storage component 210 is cuboid, the permanent magnet plate can be set as a rectangle corresponding to the corresponding side of the storage component 210. For example, in an embodiment where the first magnet component 221 is disposed on the top wall of the storage component 210 and the second magnet component 222 is disposed on the bottom wall of the storage component 210, the permanent magnet plate of the first magnet component 221 may be consistent with the shape of the top wall of the storage component 210, and the permanent magnet plate of the second magnet component 222 may be consistent with the shape of the bottom wall of the storage component 210.

[0060] The permanent magnet plate must ensure that a uniform magnetic field is formed in all areas of the storage space. In other words, the storage space must be within the magnetic field range without any blind spots.

[0061] The magnetically conductive assembly 230 includes a first magnetically conductive element 231, a second magnetically conductive element 232, and a magnetically conductive connector 233. The first magnetically conductive element 231 is correspondingly disposed with respect to the first magnet component 221. The second magnetically conductive element 232 is correspondingly disposed with respect to the second magnet component 222. The magnetically conductive connector 233 connects the first magnetically conductive element 231 and the second magnetically conductive element 232. The first magnetically conductive element 231, the second magnetically conductive element 232, and the magnetically conductive connector 233 form an annular magnetically conductive path outside the storage space.

[0062] The magnetically conductive component 230 can be made of a material with low coercivity and high permeability. The magnetically conductive path it forms can be used to concentrate the magnetic field, reduce the release of the magnetic field to the outside, and reduce interference with other components outside the storage component 210 (e.g., to prevent magnetization of other components). The magnetically conductive component 230 can be made of silicon steel sheet or similar materials.

[0063] The first magnetic conductive element 231 and the second magnetic conductive element 232 may each include a magnetic conductive plate. That is, the first magnetic conductive element 231 and the second magnetic conductive element 232 may each be a plate-like structure of a magnetic conductive plate. The magnetic conductive plates are respectively disposed corresponding to the permanent magnet plates, and the magnetic conductive connector 233 extends from the edge of the magnetic conductive plate along the outer side of the storage assembly 210 and connects to the magnetic conductive plate on the other side. For example, the magnetic conductive plate of the first magnetic conductive element 231 is attached to the permanent magnet plate of the first magnet component 221, and the magnetic conductive plate of the second magnetic conductive element 232 is attached to the permanent magnet plate of the second magnet component 222. The magnetic conductive assembly 230 may be a single piece, that is, the first magnetic conductive element 231, the second magnetic conductive element 232, and the magnetic conductive connector 233 are integrally formed. In other embodiments, the first magnetic conductive element 231, the second magnetic conductive element 232, and the magnetic conductive connector 233 may also be fixed by welding or bonding.

[0064] In an embodiment where the first magnet component 221 is disposed on the top wall of the storage assembly 210 and the second magnet component 222 is disposed on the bottom wall of the storage assembly 210, the magnetic plate of the first magnetic conductor 231 is arranged above the permanent magnet plate of the first magnet component 221, and the magnetic plate of the second magnetic conductor 232 is arranged below the permanent magnet plate of the second magnet component 222.

[0065] The projection of the storage space onto the plane of the magnetic guide plate lies within the area of ​​the magnetic guide plate, and the size of the permanent magnet plate is smaller than or equal to that of its counterpart magnetic guide plate. That is, the magnetic guide plate can be equal to or slightly larger than the corresponding side of the storage assembly 210. In the embodiment where the first magnet component 221 is disposed on the top wall of the storage assembly 210 and the second magnet component 222 is disposed on the bottom wall of the storage assembly 210, the magnetic guide plate of the first magnetic guide component 231 covers the top surface of the storage space, while the magnetic guide plate of the second magnetic guide component 232 covers the bottom surface of the storage space.

[0066] The permanent magnet plate can be smaller than the corresponding magnetic conductive plate, and its center can be aligned with that of the magnetic conductive plate. The magnetic conductive plate can concentrate the magnetic field of the permanent magnet plate, making it more uniform.

[0067] The magnetic connector 233 is used to connect the magnetic plates of the first magnetic component 231 and the second magnetic component 232. The size of the magnetic connector 233 can be set according to the state of the magnetic field. The magnetic connector 233 can be elongated and connected to the middle of one side of the magnetic plate.

[0068] The magnetic connector 233 may include a first connecting segment 235 and a second connecting segment 236. The first connecting segment 235 connects to one side of the magnetic plates of the first magnetic component 231 and the second magnetic component 232, while the second connecting segment 236 connects to the other side of the magnetic plates of the first magnetic component 231 and the second magnetic component 232. In cross-section, the first magnetic component 231, the second magnetic component 232, and the magnetic connector 233 form a ring around the outer periphery of the storage assembly 210.

[0069] In an embodiment where the first magnet component 221 and the second magnet component 222 are respectively arranged on the top wall and bottom wall of the storage assembly 210, the first connecting segment 235 extends from the middle of one side (e.g., the right side) of the first magnet component 221 along one side wall of the storage space to the middle of the corresponding side (e.g., the right side) of the second magnet component 222; the second connecting segment 236 extends from the middle of the other side (e.g., the left side) of the first magnet component 221 along the other side wall of the storage space to the middle of the other side (e.g., the left side) of the second magnet component 222.

[0070] The magnetic connector 233 can be strip-shaped, and the width of the first connecting segment 235 and the second connecting segment 236 along the front-to-back longitudinal direction is one-half to one-tenth of the length of the magnetic component 230 along the front-to-back longitudinal direction. That is, the magnetic connector 233 is located in the middle of the storage component 210 in the front-to-back direction.

[0071] The aforementioned magnetically conductive component 230, while meeting magnetic field strength requirements, reduces the use of magnetically conductive materials and magnetic components, saving costs on the magnetic field preservation container 200 and reducing the weight of both the magnetic field preservation container 200 and the refrigerator 10 as a whole. The magnetic field strength range can be set from 1Gs to 100Gs. When applied to a freezing environment, a magnetic field strength range of 5 to 60Gs is preferred, for example, around 20Gs. When applied to a refrigeration environment, a magnetic field strength range of 20 to 160Gs is preferred, preferably 40 to 80Gs, for example, around 60Gs.

[0072] Figure 5 yes Figure 2The diagram shows the magnetic field direction of the magnetic field preservation storage container 200. The magnetic field directions of the first magnet component 221 and the second magnet component 222 are set to be the same, so that a uniform magnetic field is formed in the storage space. That is, the N poles of the permanent magnet plates of the first magnet component 221 and the second magnet component 222 face in the same direction, while the S poles face in opposite directions. In the embodiment where the first magnet component 221 and the second magnet component 222 are respectively arranged on the top wall and the bottom wall of the storage assembly 210, the magnetic field direction in the storage space can be from top to bottom or from bottom to top. Figure 5 The magnetic field direction shown is from bottom to top. Based on the same technical concept, those skilled in the art can easily achieve a magnetic field in the opposite direction by adjusting the direction of the magnetic poles, that is, to achieve a magnetic field from top to bottom.

[0073] The permanent magnet magnetic field formed by the aforementioned permanent magnet plate is a static magnetic field, which ensures that the storage space always has a magnetic field of a certain strength.

[0074] Based on the above description of the vertically arranged first magnet component 221 and second magnet component 222, those skilled in the art can easily realize the horizontal or front-back arrangement of the first magnet component 221 and second magnet component 222 in storage components of other shapes.

[0075] Figure 6 Figure 7 is a schematic diagram of the magnetic field direction of a magnetic field preservation storage container 200 according to another embodiment, while Figure 8 is a schematic diagram of the cooperation between the magnet assembly 220 and the magnetic conductive assembly 230 in the magnetic field preservation storage container 200 described in Figure 6. In this embodiment, the first magnet component 221 and the second magnet component 222 are arranged left and right, and the first magnet component 221 ( Figure 6 , 7 (The image is obscured and not shown) is arranged on the right side of the storage assembly 210; the second magnetic component 222 is arranged on the left side of the storage assembly 210. Correspondingly, the magnetic plate of the first magnetic conductor 231 is located on the right side of the first magnetic component 221, and the second magnetic conductor 232 is located on the left side of the second magnetic component 222. A magnetic connector 233 connects the first magnetic conductor 231 and the second magnetic conductor 232 from the top center and bottom center of the storage assembly 210. Figure 6 The magnetic field direction shown is from right to left. Based on the same technical concept, those skilled in the art can easily achieve a magnetic field in the opposite direction by adjusting the direction of the magnetic poles, that is, to achieve a magnetic field from left to right.

[0076] Similarly, those skilled in the art should readily implement embodiments in which the first magnet component 221 and the second magnet component 222 are arranged in a front-to-back manner.

[0077] To further improve the magnetic field strength and make the magnetic field adjustable, this embodiment also provides a magnetic field preservation storage container 200 that can generate an electromagnetic field that works in conjunction with a permanent magnetic field.

[0078] Figure 8 This is a schematic diagram of a magnetic field preservation storage container 200 according to another embodiment of the present invention; Figure 9 yes Figure 8 Exploded view of the components of the magnetic field preservation storage container 200 shown; Figure 10 yes Figure 8 The diagram shows the cooperation between the magnet assembly 220 and the magnetic conductive assembly 230 in the magnetic field preservation storage container 200.

[0079] In this embodiment, the first magnet component 221 and the second magnet component 222 further add an electromagnetic ring 224 to the permanent magnet plate 223. The permanent magnet plate 223 is still disposed on the outer side of the corresponding side of the storage component 210, and the shape of the permanent magnet plate 223 is consistent with the shape of its corresponding side.

[0080] The magnetic plates of the first magnetic conductive element 231 and the second magnetic conductive element 232 are respectively disposed opposite to the permanent magnet plate 223, and the magnetic conductive connector 233 extends from the edge of the magnetic plate along the outside of the storage assembly 210 and connects to the magnetic plate on the other side.

[0081] The projection of the storage space onto the plane of the magnetic guide plate lies within the area of ​​the magnetic guide plate, and the size of the permanent magnet plate 223 is smaller than or equal to that of its counterpart magnetic guide plate. That is, the magnetic guide plate can be equal to or slightly larger than the corresponding side of the storage assembly 210. In the embodiment where the first magnet component 221 is disposed on the top wall of the storage assembly 210 and the second magnet component 222 is disposed on the bottom wall of the storage assembly 210, the magnetic guide plate of the first magnetic guide component 231 covers the top surface of the storage space, while the magnetic guide plate of the second magnetic guide component 232 covers the bottom surface of the storage space.

[0082] The permanent magnet plate 223 can be smaller than the corresponding magnetic conductive plate, and its center can be aligned with that of the magnetic conductive plate, meaning the permanent magnet plate 223 can be placed against the central area of ​​the magnetic conductive plate. The magnetic conductive plate can concentrate the magnetic field of the permanent magnet plate 223, making it more uniform.

[0083] Both the first magnet component 221 and the second magnet component 222 are further provided with electromagnetic rings 224. The electromagnetic rings 224 are disposed between the permanent magnet plate 223 and the magnetic conductive plate, or between the permanent magnet plate 223 and the corresponding side of the storage component. An electromagnetic coil is wound circumferentially within the electromagnetic rings 224. When energized, the electromagnetic coil generates an electromagnetic field that superimposes on the permanent magnet magnetic field of the corresponding permanent magnet plate 223.

[0084] The outer periphery of the electromagnetic ring 224 can be roughly the same as or slightly smaller than the permanent magnet plate 223. That is to say, the size of the electromagnetic ring 224 is smaller than or equal to the size of its relative permanent magnet plate 223.

[0085] The permanent magnet plate 223, the magnetic conductive plate, and the electromagnetic ring 224 are centered opposite each other, meaning that the magnetic conductive plate can cover the magnetic conductive plate and the electromagnetic ring 224, expanding the magnetic field coverage space within the storage space and making the magnetic field within the storage space more uniform.

[0086] The number of turns of the electromagnetic coil within the electromagnetic ring 224 can be set according to the required magnetic field strength. The direction of the electromagnetic field formed by the electromagnetic ring 224 can be set to be consistent with the direction of the permanent magnet field of the permanent magnet plate 223. In this embodiment, the magnetic plate can also concentrate the electromagnetic field, improving the uniformity of the magnetic field in the storage space.

[0087] By controlling the electromagnetic coil, the electromagnetic field can be set as needed to a static magnetic field with a constant magnetic field direction and / or magnetic field strength, an alternating magnetic field with alternating magnetic field direction and / or magnetic field strength, or a pulsed magnetic field that is activated at intervals. The above-mentioned magnetic field adjustment can be achieved by adjusting the current flowing through the electromagnetic coil. In some embodiments, the electromagnetic field can be adjusted according to the storage environment within the storage space and the storage state of the stored items. When the electromagnetic field is not activated, the basic magnetic field strength is maintained by the permanent magnet field of the permanent magnet plate 223.

[0088] The following description uses a flat drawer structure for the storage component 210 as an example to illustrate the structure of the first magnet component 221 and the second magnet component 222 arranged vertically. Those skilled in the art can easily implement a structure where the first magnet component 221 and the second magnet component 222 are arranged horizontally or vertically.

[0089] A first magnet component 221 is disposed on the top wall of the storage assembly 210, and a second magnet component 222 is disposed on the bottom wall of the storage assembly 210, and they may have substantially the same structure and size. The permanent magnet plate 223 of the first magnet component 221 has a shape consistent with the top wall of the storage assembly 210, and the permanent magnet plate 223 of the second magnet component 222 may have a shape consistent with the bottom wall of the storage assembly 210. Furthermore, the size of the magnetic conductive plate may be substantially consistent with the size of the corresponding side of the storage assembly 210.

[0090] The magnetic plate of the first magnetic conductor 231 is arranged above the permanent magnet plate 223 of the first magnet component 221, while the magnetic plate of the second magnetic conductor 232 is arranged below the permanent magnet plate 223 of the second magnet component 222. The size of the magnetic plate is greater than or equal to that of the permanent magnet plate 223, and it is disposed close to the central area of ​​the permanent magnet plate 223.

[0091] The electromagnetic ring 224 of the first magnet component 221 can be sandwiched between the magnetic plate of the first magnetic conductor 231 and the permanent magnet plate 223, or between the permanent magnet plate 223 and the top wall of the storage assembly 210. The electromagnetic ring 224 of the second magnet component 222 can be sandwiched between the magnetic plate of the second magnetic conductor 232 and the permanent magnet plate 223, or between the permanent magnet plate 223 and the bottom wall of the storage assembly 210. The magnetic plate of the first magnetic conductor 231 can evenly disperse the magnetic field of the electromagnetic ring 224 of the first magnet component 221, and the magnetic plate of the second magnetic conductor 232 can evenly disperse the magnetic field of the electromagnetic ring 224 of the second magnet component 222, thereby forming a uniform magnetic field inside the storage space.

[0092] The first connecting segment 235 extends from the middle of one side (e.g., the right side) of the first magnet component 221 along one side wall of the storage space to the middle of the corresponding side (e.g., the right side) of the second magnet component 222; the second connecting segment 236 extends from the middle of the other side (e.g., the left side) of the first magnet component 221 along the other side wall of the storage space to the middle of the other side (e.g., the left side) of the second magnet component 222.

[0093] The first connecting section 235 and the second connecting section 236 can extend from the center of the side end face of the magnetic plate along the outside of the storage assembly 210.

[0094] The magnetic connector 233 can be strip-shaped, and its size can meet the requirements for forming a magnetic conductive path, thus saving the use of magnetic conductive material, saving costs and reducing weight.

[0095] The direction of the electromagnetic field can be set to be consistent with the direction of the permanent magnet field, thereby achieving the superposition of magnetic fields and increasing the magnetic field strength. Figure 11 yes Figure 8 The diagram shows the magnetic field direction of the magnetic field preservation storage container 200. The electromagnetic fields of the first magnet component 221 and the second magnet component 222, as well as the magnetic field direction of the permanent magnet, are all set to be the same, so that a uniform magnetic field is formed within the storage space. The magnetic field direction within the storage space can be from top to bottom or from bottom to top. Figure 11 The magnetic field direction shown is from bottom to top. Based on the same technical concept, those skilled in the art can easily realize a magnetic field in the opposite direction, that is, a magnetic field from top to bottom.

[0096] The magnetic guide component 230 can improve the uniformity of the magnetic field and guide the magnetic field outside the storage space, thus preventing the magnetic field from affecting other components besides the storage component 210.

[0097] The combination structure of permanent magnet plate 223, magnetic plate, electromagnetic ring 224, and magnetic connector 233 has been optimized and improved, which makes the structure compact, saves space, facilitates assembly into storage component 210, and is beneficial for use in refrigerator 10.

[0098] Figure 12 Figure 13 is a schematic diagram of the magnetic field direction of a magnetic field preservation storage container 200 according to another embodiment, while Figure 14 is a schematic diagram of the cooperation between the magnet assembly 220 and the magnetic conductive assembly 230 in the magnetic field preservation storage container 200 described in Figure 15. In this embodiment, the first magnet component 221 and the second magnet component 222 are arranged left and right. The first magnet component 221 and the second magnet component 222 respectively include an electromagnetic ring 224 and a permanent magnet plate 223. The first magnet component 221 ( Figure 12 , 13 (The image is obscured and not shown) is arranged on the right side of the storage assembly 210; the second magnetic component 222 is arranged on the left side of the storage assembly 210. Correspondingly, the magnetic plate of the first magnetic conductor 231 is located on the right side of the first magnetic component 221, and the second magnetic conductor 232 is located on the left side of the second magnetic component 222. A magnetic connector 233 connects the first magnetic conductor 231 and the second magnetic conductor 232 from the top center and bottom center of the storage assembly 210. Figure 12 The magnetic field direction shown is from right to left. Based on the same technical concept, those skilled in the art can easily achieve a magnetic field in the opposite direction by adjusting the direction of the magnetic poles, that is, to achieve a magnetic field from left to right.

[0099] Similarly, those skilled in the art should readily implement embodiments in which the first magnet component 221 and the second magnet component 222 are arranged in a front-to-back manner.

[0100] Figure 14 This is a control system block diagram of a refrigerator 10 with a magnetic field preservation storage container 200 according to an embodiment of the present invention. The refrigerator 10 of this embodiment can also combine magnetic field control with refrigeration control to ensure that food is frozen in a magnetic field environment, achieving a preservation and freezing effect.

[0101] The refrigerator 10 can also optionally be equipped with one or more of the following: storage temperature sensor 330, open / close detector 340, and refrigeration controller 310. The storage temperature sensor 330 is used to detect the storage temperature in the storage space, and the open / close detector 340 is used to detect the open / closed status of the storage space.

[0102] Once the opening / closing detector 340 detects that the storage space has been opened, the storage temperature sensor 330 can detect whether new food has been added or whether existing food needs to be refrozen. During the cooling process, the electromagnetic ring 224 and the cooling system 320 work together to achieve magnetic field-assisted freezing, improving the freezing and preservation effect of the food.

[0103] The controller 310 is used to control the electromagnetic loop 224 and the refrigeration system 320, thereby realizing the corresponding refrigeration and magnetic field control. Various sensors (including the storage temperature sensor 330 and the opening / closing detector 340) provide detection means for the above control, thus meeting the control requirements of the control method.

[0104] The controller 310 can be configured to control the electromagnetic loop 224 to generate an electromagnetic field based on the temperature of the storage space and the operating status of the refrigerator 10. This field could be a static magnetic field with a constant magnetic field direction and / or intensity, an alternating magnetic field with varying magnetic field direction and / or intensity, or a pulsed magnetic field activated at intervals. Considering that the magnetic field has a greater effect during specific storage stages of the stored items, the controller 310 can activate the electromagnetic field when a stronger magnetic field is needed; in the normal storage compartment, a permanent magnetic field is used to maintain the basic magnetic field strength.

[0105] For example, when using a magnetic field to assist in freezing and storing food, the controller 310 can be configured to activate the electromagnetic field when a new item is placed in the storage space and the storage temperature is within a set temperature threshold range. This temperature threshold range can be set based on the temperature at which crystallization occurs during freezing, thereby increasing the magnetic field strength during crystallization. Additionally, during normal storage, the permanent magnet maintains a certain magnetic field strength, and the electromagnetic field can be periodically activated to enhance the magnetic field treatment of the stored item. This control method allows the stored item to freeze in a strong magnetic field environment, preferentially inhibiting the growth of ice crystal nuclei, reducing cell damage, preventing juice loss, ensuring better taste of the food, improving the quality of frozen storage, and meeting users' requirements for the storage quality of precious ingredients.

[0106] Therefore, those skilled in the art should recognize that although numerous exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention.
