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 schemes have emerged in existing technologies. However, some of these schemes do not achieve ideal preservation results, while others are costly to implement and impractical for household refrigerators. Among these improvement schemes, theoretical research has found that magnetic fields have a significant impact on ice crystal formation during the freezing process. The refrigerator industry is also actively exploring the introduction of magnetic fields into food preservation. However, in practical applications in refrigerators, magnetic field-assisted preservation requires a large amount of magnetic material to provide sufficient magnetic field strength, resulting in high implementation costs and significantly increasing product weight. Summary of the Invention

[0004] One object of the present invention is to provide a magnetic field preservation storage container and refrigerator that effectively improves storage quality and reduces component costs.

[0005] A further objective of this invention is to facilitate the installation and application of magnetic field preservation storage containers in refrigerators.

[0006] Specifically, the present invention provides a magnetic field preservation storage container, comprising:

[0007] A storage component, which defines a storage space for placing stored items;

[0008] One or more magnetic field components are respectively sleeved on the outer periphery of the storage component, and each magnetic field component includes:

[0009] One or more magnetic components are arranged on the outside of the storage assembly to create a magnetic field in the storage space;

[0010] A ring-shaped magnetic conductive component includes a uniform magnetic plate corresponding to a magnetic component and a connecting strip connected to the uniform magnetic plate and arranged around the outer periphery of the storage component. The uniform magnetic plate and the connecting strip form a ring-shaped magnetic conductive path outside the storage space.

[0011] Optionally, the magnetic component includes:

[0012] An electromagnetic ring has an electromagnetic coil wound around its circumference. When the electromagnetic coil is energized, it creates an electromagnetic field in the storage space.

[0013] The uniform magnetic plate is arranged at the central through hole of the electromagnetic ring, and the shape of the uniform magnetic plate is adapted to the shape of the central through hole; or the uniform magnetic plate is abutted against the electromagnetic ring.

[0014] Optionally, each magnetic field component includes two magnetic elements, which are respectively disposed on a set of opposite sides of the storage component, and a ring-shaped magnetic conductive component is provided with a uniform magnetic plate at the corresponding position of the two magnetic elements.

[0015] Optionally, the connecting strip includes two sections, each section extending from the edge of one side of the magnetic uniform plate along the outer wall of the storage assembly to the edge of the other side of the magnetic uniform plate.

[0016] Optionally, the magnetic field assembly is one, and the shapes of the two magnetic components of the magnetic field assembly are respectively consistent with the side shapes of the storage assembly to which it is arranged.

[0017] Optionally, the storage component is flat, and the two magnetic components of the magnetic field component are respectively arranged at the top and bottom of the storage component.

[0018] Optionally, there are multiple magnetic field components, which are arranged at intervals along the depth or height of the storage component.

[0019] Optionally, each magnetic field assembly is provided with a magnetic element, and the magnetic elements of adjacent magnetic field assemblies are provided on opposite sides of the storage assembly.

[0020] Optionally, the storage components include:

[0021] The cylindrical body has a forward opening; and

[0022] A drawer, which can be pulled out, is installed inside the cylinder to form a storage space.

[0023] According to another aspect of the present invention, a refrigerator is provided, comprising:

[0024] The container has a defined storage compartment inside;

[0025] Any of the above-mentioned magnetic field preservation storage containers are installed inside the storage room.

[0026] The magnetic field preservation storage container of the present invention includes one or more magnetic field components fitted around the outer periphery of the storage component to form a magnetic field within the storage space. The magnetic field helps improve storage quality, shortens freezing time, reduces juice and nutrient loss from food, lowers the number of microorganisms and bacteria, and extends the shelf life. Each magnetic field component includes one or more magnetic elements and an annular magnetic conductive member connecting the magnetic elements to form an annular magnetic conductive path on the outside of the storage space. While increasing the magnetic field strength to make the magnetic field within the storage space more uniform, the annular magnetic conductive path reduces the amount of magnetic material used, avoiding increased costs and weight caused by using too many or too large magnetic elements.

[0027] Furthermore, in the magnetic field preservation storage container of the present invention, the magnetic component can be an electromagnetic coil, which forms a magnetic field after being energized. Correspondingly, the uniform magnetic plate is configured to cooperate with the electromagnetic coil, and can be arranged at the central through hole of the electromagnetic coil or abutting against the electromagnetic coil. On the one hand, it uniformizes the magnetic field of the electromagnetic coil, and on the other hand, it also serves as part of the magnetic conduction path, thereby enhancing the magnetic flux density of the storage space and improving the magnetic field utilization efficiency.

[0028] Furthermore, the magnetic field preservation storage container of the present invention optimizes the structure of the magnetic field component, making the container more compact. It is particularly suitable for structures such as storage boxes and drawers, achieving magnetic field preservation within a relatively flat storage space. The magnetic field component has multiple optional structures, which can be selected according to the structural characteristics of the storage component, improving usability and flexibility of adjustment.

[0029] 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.

[0030] Furthermore, the refrigerator of the present invention improves the quality of stored items through a magnetic field, providing a new preservation function for smart refrigerators, meeting the increasing demands of users for smart refrigerators, and further satisfying users' quality requirements for smart homes and smart living.

[0031] The above and other objects, advantages and features of the present invention will become more apparent to those skilled in the art from the following detailed description of specific embodiments of the invention in conjunction with the accompanying drawings. Attached Figure Description

[0032] The following sections will describe some specific embodiments of the invention in detail by way of example and not limitation, with reference to the accompanying drawings. The same reference numerals in the drawings denote the same or similar parts or portions. Those skilled in the art should understand that these drawings are not necessarily drawn to scale.

[0041] Figure 9 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

[0042] 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.

[0043] 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.

[0044] One or more storage compartments of the refrigerator 10 may be equipped with magnetic field preservation storage containers 200. When placed in the freezer compartment, the magnetic field preservation storage 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 storage 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.

[0045] 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. The magnetic field preservation storage containers 200 can be arranged in the refrigerated storage compartment, the frozen storage compartment, and the variable temperature storage compartment, where magnetic field-assisted preservation is performed. They can also be used as an independent compartment of the refrigerator 10.

[0046] 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 A schematic diagram of the magnetic field component 201 and its magnetic field direction in the magnetic field preservation storage container 200 shown.

[0047] A magnetic field preservation storage container 200 generally includes a storage component 210 and one or more magnetic field components 201. The storage component 210 defines a storage space for placing stored items, and the storage component may be box-shaped. In some embodiments, the storage component may 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 lateral direction). The storage component 210 may be a drawer structure, that is, the storage component may include a cylinder and a drawer. The cylinder has a front opening. The drawer is pull-out disposed within the cylinder. 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 cylinder, it forms an independent sealed space. The construction of drawers for refrigerators is well known to those skilled in the art and will not be described in detail here.

[0048] Each magnetic field assembly 201 may include one or more magnetic elements 220 and an annular magnetic conductive member 230. The magnetic elements 220 are arranged on the outside of the storage assembly to form a magnetic field in the storage space. The magnetic elements can be permanent magnet components or electromagnetic components. In some alternative embodiments, the magnetic element 220 may include both permanent magnet components and electromagnetic components. The permanent magnet components provide a basic permanent magnetic field, while the electromagnetic components, when energized, can form an electromagnetic magnetic field superimposed on the permanent magnetic field. The magnetic field strength range can be set to 1 Gs-100 Gs. When applied to a freezing environment, the magnetic field strength range is preferably 5-60 Gs, for example, around 20 Gs; when applied to a refrigeration environment, the magnetic field strength range is 20-160 Gs, preferably 40-80 Gs, for example, around 60 Gs.

[0049] The annular magnetically conductive component 230 includes a uniform magnetic plate 231 corresponding to the magnetic component 220 and a connecting strip 232 connected to the uniform magnetic plate 231 and arranged around the outer periphery of the storage assembly 210. The uniform magnetic plate 231 and the connecting strip 232 form an annular magnetically conductive path outside the storage space. The annular 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, improve the uniformity of the magnetic field within the storage space, and reduce the release of the magnetic field to the outside, thus reducing interference to other components outside the storage assembly 210 (e.g., preventing the magnetization of other components). The annular magnetically conductive component 230 can be made of silicon steel sheet or similar materials.

[0050] The annular magnetic conductive component 230 can be a single piece, that is, the uniform magnetic plate 231 and the connecting strip 232 are integrally formed. In other embodiments, the uniform magnetic plate 231 and the connecting strip 232 can also be spliced ​​to form the annular magnetic conductive component 230.

[0051] The uniform magnetic plate 231 is arranged correspondingly to the magnetic component 220, which allows the magnetic field generated by the magnetic component 220 to be released more evenly into the storage space.

[0052] The magnetic component 220 may include an electromagnetic ring 221, in which an electromagnetic coil is wound around the ring circumferentially. When the electromagnetic coil is energized, an electromagnetic field is formed in the storage space.

[0053] The electromagnetic ring 221 can be formed by winding an electromagnetic coil, and its shape can be circular, elliptical, or square. The electromagnetic ring can be flat, with both the top and bottom being planar, and its thickness is significantly smaller than its outer circumference. The width-to-thickness ratio of the electromagnetic ring 221 can be set to a range of 1-10.

[0054] In some embodiments, the uniform magnetic plate 231 can be arranged at the central through hole of the electromagnetic ring 221, and the shape of the uniform magnetic plate 231 is adapted to the shape of the central through hole, thereby making the magnetic field assembly 201 occupy less space and making the magnetic field preservation storage container 200 more compact.

[0055] In other embodiments, the uniform magnetic plate 231 may be disposed abutting against the electromagnetic ring 221. The size of the uniform magnetic plate 231 may be larger than the outer circumference of the electromagnetic ring 221, and the electromagnetic ring 221 and the uniform magnetic plate 231 are arranged concentrically. Thus, the range of the magnetic field is expanded by utilizing the uniform magnetic plate 231.

[0056] Each magnetic field assembly 201 includes two magnetic elements 220. The two magnetic elements 220 are respectively disposed on a set of opposite sides of the storage assembly 210, and a ring-shaped magnetic guide member 230 provides uniform magnetic plates 231 at corresponding positions on the two magnetic elements 220. The position of the magnetic elements 220 can be determined according to the structure of the side on which they are located. Generally, the magnetic elements 220 can be opposite to the center of their respective side. For example, the magnetic elements 220 can be placed on the lateral sides, top and bottom sides, or front and back sides of the storage assembly 210. The magnetic poles of the magnetic elements 220 all face the storage space, allowing the magnetic field to penetrate the storage space.

[0057] When the storage component 210 is a flat rectangular parallelepiped (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 magnetic components 220 can be preferentially arranged on the top and bottom sides of the storage component 210. That is, the storage component 210 is flat, and the two magnetic components 220 of the magnetic field component 201 are respectively arranged at the top and bottom of the storage component 210. The magnetic field runs through the storage space from top to bottom or from bottom to top. This arrangement reduces the distance between the two magnetic components 220, improving the strength and uniformity of the magnetic field.

[0058] The magnetic components 220 on both sides can have roughly the same structure and size to ensure the uniformity of the magnetic field. The magnetic field of the magnetic components 220 must ensure that a uniform magnetic field is formed in all positions of the storage space. That is, the storage space is within the magnetic field range without any dead angles.

[0059] The projection of the storage space onto the plane of the uniform magnetic plate 231 lies within the area of ​​the uniform magnetic plate 231, and the size of the magnetic element 220 can be smaller than or equal to its corresponding uniform magnetic plate 231. That is, the uniform magnetic plate 231 can be equal to or slightly larger than the corresponding side of the storage assembly 210. When the magnetic element 220 is provided at the top and bottom of the storage assembly, the uniform magnetic plate 231 provided corresponding to the top magnetic element 220 can cover the top surface of the storage space respectively; the uniform magnetic plate 231 provided corresponding to the bottom magnetic element 220 can cover the bottom surface of the storage space respectively.

[0060] The uniform magnetic plate 231 can expand the coverage of the magnetic field and make the magnetic field more uniform. The connecting strip 232 may include two segments, each segment extending from the edge of one uniform magnetic plate 231 along the outer wall of the storage assembly 210 to the edge of the other uniform magnetic plate 231. In cross-section, the uniform magnetic plate 231 and the connecting strip 232 form a ring around the outer periphery of the storage assembly 210.

[0061] In an embodiment where the magnetic components 220 are respectively arranged on the top wall and bottom wall of the storage assembly 210, a connecting strip 232 extends from the middle of one side (e.g., the right side) of the top magnetic uniform plate 231 along one side wall of the storage space to the middle of the corresponding side (e.g., the right side) of the bottom magnetic uniform plate 231; another connecting strip 232 extends from the middle of the other side (e.g., the left side) of the top magnetic uniform plate 231 along the other side wall of the storage space to the middle of the other side (e.g., the left side) of the bottom magnetic uniform plate 231.

[0062] The connecting strip 232 can be strip-shaped, and its width along the front-to-back longitudinal direction is one-half to one-tenth of the length of the uniform magnetic plate 231 along the front-to-back longitudinal direction. That is, the connecting strip 232 can be located in the middle of the uniform magnetic plate 231 in the front-to-back direction, and is significantly narrower than the uniform magnetic plate 231. The above-mentioned annular magnetic conductive member 230 can reduce the use of magnetic conductive materials and magnetic components while meeting the magnetic field strength requirements, saving the cost of the magnetic field preservation storage container 200, and reducing the weight of the magnetic field preservation storage container 200 and the refrigerator 10 as a whole.

[0063] Figures 2 to 4In the illustrated embodiment, there is one magnetic field assembly 201, and the shapes of the two magnetic elements 220 of the magnetic field assembly 201 are respectively consistent with the side shapes of the storage assembly 210 on which it is arranged. For example, the top magnetic element 220 can be consistent with the top surface shape of the storage assembly 210, and the bottom magnetic element 220 can be consistent with the bottom surface shape of the storage assembly 210. A top uniform magnetic plate 231 is provided above the top magnetic element 220, and a bottom uniform magnetic plate 231 is provided below the bottom magnetic element 220. The top uniform magnetic plate 231 covers the top surface of the storage space; the bottom uniform magnetic plate 231 can cover the bottom surface of the storage space. A longitudinal magnetic field without dead angles is formed in the storage space. The connecting strip 232 is located at the center position in the front-to-back longitudinal direction of the magnetic field assembly 201, thereby forming a magnetic conductive path on the outside of the storage space and preventing the magnetic field from leaking outward.

[0064] The magnetic fields of the two magnetic components 220 are set to the same direction, creating a uniform magnetic field within the storage space. That is, the N poles of the two magnetic components 220 point in the same direction, while the S poles point in opposite directions. The magnetic field direction within the storage space can be from top to bottom or from bottom to top. Figure 4 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.

[0065] Based on the above description of the embodiment where the magnetic component 220 and the uniform magnetic plate 231 are respectively arranged at the top and bottom, those skilled in the art can easily implement the above-mentioned scheme where the magnetic component 220 and the uniform magnetic plate 231 are respectively arranged on the left and right side walls and the front and rear side walls. Considering that the electromagnetic ring 221 will generate heat during the process of generating a magnetic field when energized, the distance between the magnetic component and the stored item in the storage space can be set to not less than 1 mm.

[0066] Figure 5 This is a schematic diagram of a magnetic field preservation storage container 200 according to another embodiment of the present invention; Figure 6 yes Figure 5 The diagram shows the arrangement of the electromagnetic ring 221 in the magnetic field preservation storage container 200. In this embodiment, there are multiple magnetic field components 201, which are arranged at intervals along the depth or height direction of the storage component 210. Each magnetic field component 201 still has two magnetic elements 220. The two magnetic elements 220 are respectively disposed on a set of opposite sides of the storage component 210, and the annular magnetic conductive member 230 is provided with uniform magnetic plates 231 at corresponding positions of the two magnetic elements 220.

[0067] For the structure in which the magnetic field components 201 are spaced apart along the depth of the storage component 210, the magnetic elements 220 can be placed on the lateral sides or the top and bottom sides of the storage component 210. Multiple magnetic field components 201 form a set of magnetic fields, and the magnetic fields of multiple magnetic field components 201 are superimposed on each other, which can make the magnetic field in the storage space more uniform.

[0068] For the structure in which the magnetic field components 201 are spaced apart along the height direction of the storage component 210, the magnetic components 220 can be placed on the lateral sides or the front and rear sides of the storage component 210.

[0069] Magnetic component 220 can also use electromagnetic ring 221. An electromagnetic coil is wound around the inside of the electromagnetic ring 221 along its circumference. When the electromagnetic coil is energized, an electromagnetic field is generated in the storage space. The uniform magnetic plate of the annular magnetic conductive component 230 can be abutted against the electromagnetic ring 221. The size of the uniform magnetic plate of the annular magnetic conductive component 230 can be larger than the outer circumference of the electromagnetic ring 221, and the electromagnetic ring 221 and the uniform magnetic plate of the annular magnetic conductive component 230 are co-centered. The uniform magnetic plate of the annular magnetic conductive component 230 expands the range of the magnetic field.

[0070] Multiple uniform magnetic plates located on the same side of the storage component 210 can cover the area of ​​that side of the storage space. Multiple uniform magnetic plates located on the top surface of the storage space can cover the top surface area of ​​the storage space, while multiple uniform magnetic plates located on the bottom surface of the storage space can cover the bottom surface area of ​​the storage space. By reducing the size of each electromagnetic ring 221, the magnetic field generated by the electromagnetic ring 221 can be made more uniform, ensuring that the stored items in the storage space are treated with a uniform magnetic field.

[0071] The number of magnetic field components 201 can be set according to the size of the storage component 210. The figure shows the structure of a magnetic field preservation storage container 200 with two magnetic field components 201. Those skilled in the art can set three or more magnetic field components 201 as needed.

[0072] Multiple magnetic field components 201 can be configured to be identical. For example, a magnetic field preservation storage container 200 with two magnetic field components 201 can be arranged symmetrically front to back.

[0073] Figure 7 This is a schematic diagram of a magnetic field preservation storage container 200 according to another embodiment of the present invention. Figure 8 yes Figure 7The diagram shows the arrangement of the magnetic components 220 in the magnetic field preservation storage container 200. In this embodiment, there are also multiple magnetic field components 201, which are arranged at intervals along the depth or height direction of the storage component 210. Each magnetic field component 201 may include one magnetic component 220. The magnetic component 220 is arranged on one side of the storage component 210, and the uniform magnetic plate of the annular magnetic guiding member 230 is correspondingly arranged with the magnetic component 220. The connecting strip of the annular magnetic guiding member 230 is arranged around the storage component 210 from one side of the uniform magnetic plate of the annular magnetic guiding member 230 and then connected to the other side of the uniform magnetic plate of the annular magnetic guiding member 230.

[0074] Multiple magnetic field components 201 can maintain the uniformity of the magnetic field to a certain extent by placing the magnetic elements 220 in different positions. For example, the magnetic elements 220 of adjacent magnetic field components 201 are placed on opposite sides of the storage component 210.

[0075] In an embodiment with two magnetic field components 201, the magnetic element 220 of the front magnetic field component 201 can be disposed on the top of the storage component 210, while the magnetic element 220 of the rear magnetic field component 201 can be disposed on the bottom of the storage component 210. The front magnetic field component 201 and the rear magnetic field component 201 can be symmetrically arranged and have the same structure and size.

[0076] The magnetic elements 220 of adjacent magnetic field components 201 are disposed on opposite sides of the storage component 210. The specific structure of having four magnetic field components 201 is as follows: the magnetic elements 220 of the front magnetic field component 201 can be disposed on the top of the storage component 210; the magnetic elements 220 of the front middle magnetic field component 201 can be disposed on the bottom of the storage component 210; the magnetic elements 220 of the rear middle magnetic field component 201 can be disposed on the top of the storage component 210; and the magnetic elements 220 of the rear magnetic field component 201 can be disposed on the bottom of the storage component 210.

[0077] In the embodiment where one magnetic element 220 is provided for each magnetic field component 201, the amount of magnetic element 220 used is greatly reduced, which is especially suitable for storage components 210 with small storage space. The annular magnetic conductive component 230 maintains good magnetic field uniformity.

[0078] Figure 9 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.

[0079] The refrigerator 10 in this embodiment can also combine magnetic field control with refrigeration control to ensure that food is frozen in a magnetic field environment, thereby achieving the effect of preservation and freezing.

[0080] 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.

[0081] 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 magnetic field component 201 and the cooling system 320 work together to achieve magnetic field-assisted freezing, improving the freezing and preservation effect of the food.

[0082] The controller 310 is used to control the magnetic field component 201 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.

[0083] The controller 310 can be configured to control the magnetic field component 201 to generate an electromagnetic field, such as 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, based on the temperature of the storage space and the operating status of the refrigerator 10.

[0084] 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 electromagnetic field can be periodically activated to intensify the magnetic field treatment on 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 damage to cells, 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.

[0085] The refrigerator 10 and its magnetic field preservation storage container 200 of the above embodiments, through optimization of the structure of the magnetic field component 201, make the magnetic field preservation storage container 200 more compact, especially suitable for storage boxes and storage drawers, achieving magnetic field preservation within a relatively flat storage space. The magnetic field component 201 has a variety of optional structures, which can be selected according to the structural characteristics of the storage component 210, improving usability and flexibility of adjustment.

[0086] The refrigerator 10 and its magnetic field preservation storage container 200 of the above embodiments, while increasing the magnetic field strength to make the magnetic field in the storage space more uniform, reduce the amount of magnetic material used by using an annular magnetic conductive path, avoiding the increased cost and weight caused by using too many or too large magnetic components. Verification of the prototype product shows that the magnetic field preservation storage container 200 allows food to be stored in a magnetic field environment, inhibiting the growth of ice crystal nuclei. The ice crystal growth rate is higher than the water molecule migration rate, resulting in smaller ice crystals, thereby reducing damage to cells, 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.

[0087] 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. Thus, the scope of the present invention should be understood and construed as covering all such other variations or modifications.
