When in use, the first magnetic field generating member and the second magnetic field generating member generate a magnetic field that acts on the storage space, thereby causing the magnetic field to act on the food in the storage space. During the freezing process, the magnetic field restricts the degrees of freedom of water molecules, breaks hydrogen bonds within water molecule clusters, thereby suppressing the growth of crystal nuclei in the food, generating small ice crystals inside the food, and further reducing damage to food cells by ice crystals. Therefore, it reduces the leakage of meat juices after thawing the food, thereby reducing nutrient loss from the food and contributing to ensuring the texture of the food. During the refrigeration process, the magnetic field can reduce the degree of supercooling of the food. That is, by applying a magnetic field, the food can maintain an unfrozen state at a lower temperature. In other words, the refrigeration temperature of the food can be lowered, thereby further suppressing bacterial growth and contributing to the preservation of the freshness of the food. Furthermore, because the first and second magnetic field generating members are positioned on opposite sides of the magnetic conduit plate, the magnetic fields of both members are induced by the magnetic conduit plate, resulting in a more uniform distribution of the magnetic field within the storage space. This achieves an optimal freshness preservation effect through a magnetic field under lower cost conditions.

[0024] Furthermore, the storage container of the present invention arranges the magnetic field device in the storage space and provides intervals between the magnetic field device and two opposing inner walls of the storage space respectively. In view of the special structure of the magnetic field device, that is, the first magnetic field generating member and the second magnetic field generating member are attached to both sides of the magnetic conductive plate, the magnetic field device is arranged in the storage space, and the magnetic conductive plate can induce and diffuse the magnetic fields of the first magnetic field generating member and the second magnetic field generating member towards the storage spaces on both sides respectively, thereby further improving the uniformity of the magnetic field distribution in the storage space and contributing to the improvement of the freshness retention effect of food ingredients.

[Modes for carrying out the invention]

[0028] Those skilled in the art should understand that the embodiments described below represent only a limited number of embodiments of the present invention, and not all embodiments of the present invention. These limited embodiments are intended to illustrate the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. All other embodiments that can be obtained by those skilled in the art without any creative work based on the embodiments of the present invention should still be included within the scope of protection of the present invention.

[0029] In the description of the present invention, the orientations or positional relationships indicated by terms such as "center," "thickness," "top," "bottom," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inside," "outside," "axial direction," "radial direction," and "circumferential direction" are based on the orientations or positional relationships shown in the drawings and are merely for the purpose of facilitating and simplifying the description of the present invention. They do not mean that the indicated or implied device or element needs to have a specific orientation, or needs to be composed of and operated in a specific orientation, and therefore should not be understood as limitations of the present invention.

[0030] As shown in Figures 1 to 3, in one embodiment, the storage container includes a storage body 100 and a magnetic field device 200. The storage body 100 forms a storage space 101. The magnetic field device 200 is provided on the inner wall of the storage space 101 and generates a magnetic field within the storage space 101. The magnetic field device 200 includes a first magnetic field generating member 210, a second magnetic field generating member 220, and a magnetic guide plate 230. The first magnetic field generating member 210 and the second magnetic field generating member 220 are each arranged on both sides of the magnetic guide plate 230.

[0031] Referring to Figures 1 to 3, specifically, the first magnetic field generating member 210 and the second magnetic field generating member 220 are magnetic pieces. The two magnetic pieces are in close contact with both sides of the magnetic conduit plate 230. In other words, the magnetic conduit plate 230 is sandwiched between the two magnetic pieces. The area of ​​the mounting surface on the magnetic conduit plate 230 to which the first magnetic field generating member 210 is attached is larger than the area of ​​the first magnetic field generating member 210, so that the projection of the first magnetic field generating member 210 onto its mounting surface is contained within the mounting surface. The area of ​​the mounting surface on the magnetic conduit plate 230 to which the second magnetic field generating member 220 is attached is larger than the area of ​​the second magnetic field generating member 220, so that the projection of the second magnetic field generating member 220 onto its mounting surface is contained within the mounting surface. The storage body 100 is a drawer, and when in use, the opening of the drawer faces upward.

[0032] Referring to Figures 1 to 3, in one embodiment of this model, the magnetic field device 200 is installed on the inner bottom wall of the storage space 101. Since both the magnetic piece and the magnetic guide plate 230 have a flattened structure, the entire magnetic field device 200 can also be considered to have a flattened structure. Therefore, the magnetic field device 200 can cover the inner bottom wall of the storage space 101, with the side of the magnetic guide plate 230 to which the first magnetic field generating member 210 is attached facing the opening of the drawer, and the side to which the second magnetic field generating member 220 is attached facing the inner bottom wall of the drawer.

[0033] Furthermore, the side of the magnetic guide plate 230 to which the second magnetic field generating member 220 is attached can be oriented toward the drawer opening, and the side to which the first magnetic field generating member 210 is attached can be oriented toward the inner bottom wall of the drawer. In addition, the magnetic field device 200 can be positioned on the inner walls of the storage space 101, namely the inner side of the left wall, the inner side of the right wall, the inner side of the rear wall, and the inner side of the front wall.

[0034] As shown in combination with Figures 1 and 4, in one embodiment of this model, the magnetic field device 200 is placed on the outer bottom wall of the storage space 101, generating a magnetic field within the storage space 101. Specifically, the magnetic field device 200 can cover the outer bottom wall of the drawer. Alternatively, the magnetic field device 200 can be directly fixed to the outer bottom wall of the drawer. Or, a concave plate with a groove can be provided, the magnetic field device 200 can be first placed in the groove of the concave plate, and then the concave plate can be fixed to the storage body 100, thereby fixing the magnetic field device 200 within the space enclosed by the groove and the outer bottom wall of the drawer.

[0035] Furthermore, it should be noted that the magnetic field device 200 can also be positioned on the outer walls of the drawer, namely the outer left wall, outer right wall, outer rear wall, and outer front wall.

[0036] In this embodiment, a magnetic field device 200 is placed inside or on the outer wall of the storage space 101, and the magnetic field device 200 includes a magnetic conductor plate 230 and a first magnetic field generating member 210 and a second magnetic field generating member 220 positioned on both sides of the magnetic conductor plate 230. When in use, the energized first magnetic field generating member 210 and the second magnetic field generating member 220 generate a magnetic field that acts on the storage space 101, thereby causing the magnetic field to act on the food in the storage space 101. During the freezing process, the magnetic field restricts the degrees of freedom of water molecules, breaks hydrogen bonds within water molecule clusters, thereby suppressing the growth of crystal nuclei in the food, generating small ice crystals inside the food, and further reducing damage to food cells by ice crystals. Therefore, it reduces the leakage of meat juices after thawing the food, thereby reducing nutrient loss in the food and contributing to ensuring the texture of the food.

[0037] During the refrigeration process, a magnetic field can reduce the degree of supercooling of food. In other words, by applying a magnetic field, food can remain in an unfrozen state at a lower temperature. To put it another way, the refrigeration temperature of food can be lowered, thereby further suppressing bacterial growth and contributing to the preservation of food freshness.

[0038] Furthermore, because the first magnetic field generating member 210 and the second magnetic field generating member 220 are positioned on both sides of the magnetic guide plate 230, the magnetic fields of both the first magnetic field generating member 210 and the second magnetic field generating member 220 are both induced by the magnetic guide plate 230, thereby resulting in a more uniform distribution of the magnetic field within the storage space 101. This achieves an optimal freshness preservation effect using a magnetic field under lower cost conditions.

[0039] Referring to Figure 1, furthermore, the distribution directions of the two magnetic poles of the first magnetic field generating member 210 and the two magnetic poles of the second magnetic field generating member 220 are the same, and the distribution direction of the two magnetic poles of the first magnetic field generating member 210 is perpendicular to the surface of the magnetic guide plate 230 to which the first magnetic field generating member 210 is attached.

[0040] Referring to Figure 1, specifically, the distribution directions of the north and south poles of the two magnetic pieces are the same, and both distribution directions are perpendicular to the surface on the magnetic guide plate 230 to which the magnetic pieces are attached. For example, if the upper surface of the magnetic piece above the magnetic guide plate 230 is the north pole and the lower surface is the south pole, then the magnetic piece below the magnetic guide plate 230 will similarly have the upper surface as the north pole and the lower surface as the south pole. This allows the magnetic fields of the first magnetic field generating member 210 and the second magnetic field generating member 220 to be superimposed, contributing to an increase in magnetic field strength.

[0041] Furthermore, preferably, the magnetic guide plate 230 is made of a material with a relative permeability greater than 1, such as a ferromagnetic material or a permanent magnetic material. Here, relative permeability represents the ratio of the permeability of the material to the vacuum permeability.

[0042] As shown in Figures 1 and 5, in one embodiment, the magnetic field device 200 is arranged in the storage space 101, and there is a gap between the magnetic field device 200 and the two opposing inner walls of the storage space 101. The two sides of the magnetic guide plate 230 to which the first magnetic field generating member 210 and the second magnetic field generating member 220 are attached face the two opposing inner walls of the storage space which are spaced apart from the magnetic field device 200.

[0043] Furthermore, the storage container includes a support member 300. The support member 300 is located within the storage space 101, and the magnetic field device 200 is fixed to the support member 300, thereby positioning the magnetic field device 200 within the storage space 101.

[0044] Referring to Figures 1 and 5, in one embodiment of this model, the support member 300 is plate-shaped and has a housing groove, and the magnetic field device 200 is arranged within the housing groove. Specifically, one end of the plate-shaped support member 300 is in contact with the rear side wall of the drawer, and the other end is in contact with the front side wall of the drawer, thereby dividing the storage space 101 inside the drawer into two parts distributed to the left and right. The support member 300 forms a housing groove, and the magnetic field device 200 is arranged within the housing groove. In Figure 5, the magnetic field device 200 is shown as a transparent view with a dotted line.

[0045] Specifically, the thickness of the support member 300 is greater than the thickness of the magnetic field device 200, and a housing groove having a thickness greater than or equal to the thickness of the magnetic field device 200 is provided inside the support member 300. The opening of the housing groove faces the opening of the drawer, so that the magnetic field device 200 can be inserted directly into the housing groove from above the opening of the drawer, and the magnetic field device 200 can be positioned inside the storage space 101. There is also a gap between the magnetic field device 200 and the opposing left and right inner walls of the storage space 101. The two sides of the magnetic guide plate 230 to which the first magnetic field generating member 210 and the second magnetic field generating member 220 are attached face the left and right inner walls of the storage space 101. That is, one magnetic piece is located between the left wall of the storage space 101 and the magnetic guide plate 230, and the other magnetic piece is located between the right wall of the storage space 101 and the magnetic guide plate 230.

[0046] In this embodiment, the magnetic field device 200 is placed inside the storage space 101, and a gap is provided between the magnetic field device 200 and the two opposing inner walls of the storage space 101. Considering the special structure of the magnetic field device 200, namely the first magnetic field generating member 210 and the second magnetic field generating member 220 being arranged on both sides of the magnetic guide plate 230, after the magnetic field device 200 is placed inside the storage space 101, the magnetic guide plate 230 can guide and diffuse the magnetic fields of the first magnetic field generating member 210 and the second magnetic field generating member 220 toward the storage space 101 on both sides. This further improves the uniformity of the magnetic field distribution within the storage space 101, contributing to an improved freshness preservation effect for food. It also contributes to an improvement in the magnetic equalization efficiency of the magnetic guide plate 230.

[0047] Furthermore, by providing a accommodating groove in the support member 300, the magnetic field device 200 can be placed inside the accommodating groove, which has the effect of protecting the magnetic field device 200 and avoiding impacts to the magnetic field device 200.

[0048] Furthermore, the support member 300 can also be provided so as to be in contact with the left and right side walls of the drawer, thereby dividing the storage space 101 of the drawer into two parts distributed front to back. That is, the side of the magnetic guide plate 230 to which the first magnetic field generating member 210 is attached should be perpendicular to the plane in which the opening of the drawer is located.

[0049] Furthermore, the opening of the housing groove of the support member 300 can be directed towards the side wall of the drawer, meaning that after assembly is complete, the opening of the housing groove of the support member 300 is blocked by the side wall of the drawer. In this case, during assembly, it is necessary to first place the magnetic field device 200 into the housing groove, and then assemble the integrated unit consisting of the magnetic field device 200 and the support member 300 into the storage space 101. Alternatively, a notched area corresponding to the opening of the housing groove of the support member 300 can be provided in the side wall of the drawer. Alternatively, the side wall of the drawer can be recessed into the storage space 101 to form an open groove, the groove opening of the housing groove of the support member 300 can be made to correspond with the groove opening of the open groove, the support member 300 can be inserted into the open groove, and then the magnetic field device 200 can be inserted into the housing groove from the groove opening of the open groove and the groove opening of the housing groove.

[0050] As shown in combination with Figures 1 and 6, in one embodiment of this model, the support member 300 is a partition plate, and the magnetic field device 200 is positioned within the storage space 101 by being attached to the surface of the partition plate. Exemplarily, the partition plate is in contact with the front inner wall and the rear inner wall of the drawer, and the magnetic field device 200 is in close contact with the surface of the partition plate facing the left inner wall of the drawer or the surface facing the right inner wall of the drawer.

[0051] Furthermore, it should be noted that the support member 300 can be molded separately from the storage body 100 and assembled later, or it can be molded integrally with it. In the example where the support member 300 has a storage groove, the side wall of the drawer can be recessed into the storage space 101 to form the storage groove, and the support member 300 can be molded integrally with the drawer.

[0052] As shown in Figures 7 and 8, in one embodiment of this model, the support member 300 includes a base plate 310, a main support plate 320, a first sub-support plate 330, and a second sub-support plate 340. The main support plate 320, the first sub-support plate 330, and the second sub-support plate 340 protrude from the surface of the base plate 310 in the same direction and are parallel to each other. The main support plate 320 is located between the first sub-support plate 330 and the second sub-support plate 340, and the magnetic field device 200 is attached to the main support plate 320. The wall portion of the storage body 100 is recessed into the storage space 101 to form a mounting groove, and the support member 300 assembled to the storage body 100 has the main support plate 320 fitted into the mounting groove, and the first sub-support plate 330 and the second sub-support plate 340 are located outside the two opposing outer walls of the storage body 100, respectively.

[0053] Referring to Figures 7 and 8, specifically, the rear and bottom walls of the drawer are recessed into the storage space 101 to form mounting grooves. That is, the mounting grooves have openings on the rear and bottom sides of the drawer. The support member 300 to which the magnetic field device 200 is fixed can be assembled to the drawer from rear to front or from bottom to top, thereby fitting the main support plate 320 into the mounting groove, and simultaneously positioning the first sub-support plate 330 and the second sub-support plate 340 on the outside of the left and right side walls of the drawer, respectively.

[0054] In this embodiment, by providing a base plate 310, a main support plate 320, a first sub-support plate 330, and a second sub-support plate 340 on the support member 300, when assembling the support member 300 to the storage body 100, assembly with the storage body 100 can be achieved through contact between the base plate 310, the main support plate 320, the first sub-support plate 330, and the second sub-support plate 340 and the storage body 100, as well as the mutual clamping action between the main support plate 320 and the first sub-support plate 330 and the second sub-support plate 340. This eliminates the need for additional connecting parts and is advantageous in simplifying the assembly process between the storage body 100 and the support member 300.

[0055] Furthermore, the support member 300 can also be assembled by directly providing grooves in the rear and bottom walls of the drawer.

[0056] It should also be noted that since the drawer is a storage unit that needs to be moved when in use, the two walls of the drawer need to be adjusted to accommodate the support members. In the case of a fixed storage unit, it is sufficient to simply recess the wall portion of the storage unit 100 facing its own opening into the storage space 101 to form a mounting groove.

[0057] As shown in Figure 9, the storage container further includes two magnetic field members 400. The two magnetic field members 400 are attached to the inside or outside of two opposing side walls of the storage space 101, where the two sides to which the first magnetic field generating member 210 and the second magnetic field generating member 220 of the magnetic guide plate 230 are attached face each other.

[0058] Specifically, the two sides of the magnetic guide plate 230 to which the first magnetic field generating member 210 and the second magnetic field generating member 220 are attached face the left and right side walls of the storage space 101, and the two magnetic field members 400 are attached to the outside of the left and right walls of the drawer. Here, the magnetic field member 400 includes a magnetic member and a magnetic equalizing plate, and the magnetic member and the magnetic equalizing plate are in close contact, forming a plate-like structure as a whole. For example, the magnetic member can be a magnetic piece or a coil, and the coil generates a magnetic field when energized. Alternatively, the magnetic field member 400 may include only a magnetic member.

[0059] The magnetic field member 400 can also be installed on the inner wall of the drawer.

[0060] It should also be noted that if the two sides of the magnetic guide plate 230 to which the first magnetic field generating member 210 and the second magnetic field generating member 220 are attached face the front and rear side walls of the storage space 101, the two magnetic field members 400 are attached to the outside or inside of the front and rear side walls of the drawer, respectively.

[0061] In this embodiment, by arranging the magnetic field member 400 on the inside or outside of the two opposing side walls of the storage space 101, where the two sides to which the first magnetic field generating member 210 and the second magnetic field generating member 220 of the magnetic guide plate 230 are attached face each other, the magnetic field strength within the storage space 101 is increased, and further contributing to improving the uniformity of the magnetic field distribution within the storage space 101.

[0062] Furthermore, under conditions where the magnetic field device 200 is attached to the support member 300 and the support member 300 has a main support plate 320, a first sub-support plate 330, and a second sub-support plate 340, the magnetic field member 400 can also be attached to the side wall of the housing body 100, or to the first sub-support plate 330 and the second sub-support plate 340. Alternatively, mounting grooves can be provided in the first sub-support plate 330 and the second sub-support plate 340, and the magnetic field member can be placed in the mounting grooves.

[0063] Referring to Figures 1 and 10, in one embodiment, the storage body 100 is the inner box of the refrigerator, and the inner box defines the storage space 101. When in use, the storage space 101 has an opening facing forward of the storage body 100.

[0064] In one embodiment of this model, the magnetic field device 200 is placed in the storage space 101, and there is a gap between the magnetic field device 200 and two opposing inner walls of the storage space 101. The two sides of the magnetic guide plate 230 to which the first magnetic field generating member 210 and the second magnetic field generating member 220 are attached face the two opposing inner walls of the storage space that are spaced apart from the magnetic field device 200. Specifically, there is a gap between the magnetic field device 200 and the opposing upper and lower inner walls of the inner box. The two sides of the magnetic guide plate 230 to which the first magnetic field generating member 210 and the second magnetic field generating member 220 are attached face the upper and lower inner walls of the inner box.

[0065] The storage space 101 defined by the inner box can be a refrigerator compartment, a chiller compartment, or a freezer compartment.

[0066] Referring to Figures 1 and 11, in one embodiment of this model, there is a gap between the magnetic field device 200 and the opposing left and right inner walls of the inner box. The two sides of the magnetic guide plate 230 to which the first magnetic field generating member 210 and the second magnetic field generating member 220 are attached face the left and right inner walls of the inner box, respectively.

[0067] Furthermore, a support member 300 is placed inside the inner box, the support member 300 is plate-shaped and has a housing groove, and the magnetic field device 200 is placed inside the housing groove.

[0068] The support member 300 can also be a partition plate, and the magnetic field device 200 is in close contact with the partition plate.

[0069] Specifically, the mounting method for the magnetic field device 200 when the storage body 100 is an inner box can refer to the mounting method when the storage body 100 is a drawer, that is, the structure of the support member 300 can refer to the embodiment when the storage body 100 is a drawer.

[0070] The magnetic field device 200 can also be placed on the inner wall or outer wall of the storage space 101. For example, it can be placed on the outer side of the upper wall, the outer side of the left wall, the outer side of the right wall, or the outer side of the lower wall, or it can be placed on the inner side of the upper wall, the inner side of the left wall, the inner side of the right wall, or the inner side of the lower wall.

[0071] As shown in Figure 12, in one embodiment, the storage body 100 forms a plurality of storage spaces 101, the magnetic field device 200 is positioned between two storage spaces 101, and the surfaces on which the first magnetic field generating member 210 and the second magnetic field generating member 220 of the magnetic conductor plate 230 are positioned face the two storage spaces 101. Specifically, the storage body 100 can be a refrigerator body, and a plurality of compartments are defined as storage spaces 101, for example, a refrigerator compartment and a freezer compartment, or a refrigerator compartment and a chiller compartment. The magnetic field device 200 is positioned between the two storage spaces 101, i.e., within the foam layer of the refrigerator body. Since the two storage spaces 101 are distributed vertically, the sides on which the first magnetic field generating member 210 and the second magnetic field generating member 220 of the magnetic conductor plate 230 are positioned face the bottom of the upper storage space 101 and the top of the lower storage space 101, respectively.

[0072] By installing the magnetic field device 200 between the two storage spaces 101, the magnetic field device 200 can exert a magnetic field effect on the two storage spaces 101, thereby improving the operational efficiency of the magnetic field device 200.

[0073] Furthermore, a single drawer or inner box can also form multiple storage spaces.

[0074] Referring to Figures 1 to 12, preferably in one embodiment, the ratio of the projected area of ​​the first magnetic field generating member 210 on a plane perpendicular to its centerline to the projected area of ​​the first magnetic field generating member 210 on a plane perpendicular to its centerline in the storage space 101 is 0.8.

[0075] Furthermore, the ratio of the projected area of ​​the second magnetic field generating member 220 on a plane perpendicular to its centerline to the projected area of ​​the second magnetic field generating member 220 on a plane perpendicular to its centerline in the storage space 101 is 0.8.

[0076] Specifically, referring to Figure 12, assuming a projection plane perpendicular to the center line of the first magnetic field generating member 210, that is, a plane perpendicular to the vertical direction, if we let S1 be the projected area of ​​the first magnetic field generating member 210 on the projection plane and S2 be the projected area of ​​the storage space 101 on the projection plane, then S1 = 0.8S2. Similarly, if we let S3 be the projected area of ​​the second magnetic field generating member 220 on the projection plane and S2 be the projected area of ​​the storage space 101 on the projection plane, then S3 = 0.8S2.

[0077] Furthermore, the ratio of the area enclosed by the edges of the projection of the first magnetic field generating member 210 onto a plane perpendicular to the center line to the area projected onto a plane perpendicular to the center line of the storage space 101 may be between 0.3 and 1.5, such as 0.3, 0.5, 0.6, 0.7, 1, 1.5, etc.

[0078] Similarly, the ratio of the area enclosed by the edges of the projection of the second magnetic field generating member 220 onto a plane perpendicular to its centerline to the projected area of ​​the second magnetic field generating member 220 onto a plane perpendicular to its centerline in the storage space 101 may be between 0.3 and 1.5, such as 0.3, 0.5, 0.6, 0.7, 1, 1.5, etc.

[0079] The ratio of the projected area between the two magnetic field generating members and the storage space may be different.

[0080] By setting the ratio of the projected area of ​​the first magnetic field generating member 210 on a plane perpendicular to its centerline to the projected area of ​​the first magnetic field generating member 210 on a plane perpendicular to its centerline in the storage space 101 to between 0.3 and 1.5, the covering effect of the magnetic field generated by the first magnetic field generating member 210 within the storage space 101 is ensured, contributing to guaranteeing the effect of the magnetic field on the food. Similarly, by setting the ratio of the projected area of ​​the second magnetic field generating member 220 on a plane perpendicular to its centerline to the projected area of ​​the second magnetic field generating member 220 on a plane perpendicular to its centerline in the storage space 101 to between 0.3 and 1.5, the covering effect of the magnetic field generated by the second magnetic field generating member 220 within the storage space 101 is ensured, contributing to guaranteeing the effect of the magnetic field on the food.

[0081] As shown in Figure 13, in one embodiment, the first magnetic field generating member 210 and the second magnetic field generating member 220 are electromagnetic coils. The two electromagnetic coils are in close contact with both sides of the magnetic guide plate 230, and the electromagnetic coils generate a magnetic field after being energized.

[0082] Specifically, referring to Figures 14 to 22, the mounting method of the magnetic field device 200 to the housing body under the condition that the first magnetic field generating member 210 and the second magnetic field generating member 220 are electromagnetic coils is the same as the mounting method of the magnetic field device 200 to the housing body under the condition that the first magnetic field generating member 210 and the second magnetic field generating member 220 are magnetic pieces, and is the same as the explanation above, so it will not be repeated here.

[0083] Under the condition that the first magnetic field generating member 210 and the second magnetic field generating member 220 are electromagnetic coils, the distribution directions of the two magnetic poles of the first magnetic field generating member 210 and the two magnetic poles of the second magnetic field generating member 220 are the same, and the distribution direction of the two magnetic poles of the first magnetic field generating member 210 is perpendicular to the surface of the magnetic guide plate 230 to which the first magnetic field generating member 210 is attached.

[0084] The direction of the magnetic field generated by the electromagnetic coil after it is energized is distributed along the centerline of its winding. That is, the centerline of the electromagnetic coil is perpendicular to the surface of the magnetic guide plate 230 on which the electromagnetic coil is attached. Furthermore, the current direction of the two electromagnetic coils is the same, which results in the same distribution direction of the magnetic poles of the two electromagnetic coils.

[0085] Furthermore, preferably, the magnetic guide plate 230 is made of a material with a relative permeability greater than 1, such as a ferromagnetic material or a permanent magnetic material. Here, relative permeability represents the ratio of the permeability of the material to the vacuum permeability.

[0086] Referring to Figures 14 and 22, in one embodiment, the ratio of the area enclosed by the edges of the projection of the first magnetic field generating member 210 onto a plane perpendicular to the center line of the storage space 101 to the area of ​​the projection of the first magnetic field generating member 210 onto a plane perpendicular to the center line is 0.9.

[0087] Furthermore, the ratio of the area enclosed by the edges of the projection of the second magnetic field generating member 220 onto a plane perpendicular to its centerline to the projection area of ​​the second magnetic field generating member 220 onto a plane perpendicular to its centerline in the storage space 101 is 0.9.

[0088] Specifically, referring to Figure 22, with respect to a plane perpendicular to the center line of the first magnetic field generating member 210, i.e., a plane perpendicular to the vertical direction, the first magnetic field generating member 210 and the second magnetic field generating member 220 are annular. Therefore, the area enclosed by the edges of the projection of the first magnetic field generating member 210 onto the plane perpendicular to its center line includes the area corresponding to the annular hollow portion. Assuming a projection plane, if the projected area of ​​the first magnetic field generating member 210 onto the projection plane (including the area corresponding to the annular hollow portion) is S1 and the projected area of ​​the storage space 101 onto the projection plane is S2, then S1 = 0.9S2. If the projected area of ​​the first magnetic field generating member 210 onto the projection plane (including the area corresponding to the annular hollow portion) is S3 and the projected area of ​​the storage space 101 onto the projection plane is S2, then S3 = 0.9S2.

[0089] Furthermore, the ratio of the area enclosed by the edges of the projection of the first magnetic field generating member 210 onto a plane perpendicular to its centerline to the area of ​​the storage space 101 projected onto a plane perpendicular to its centerline may be between 0.5 and 1.5, such as 0.5, 0.6, 0.7, 1, 1.5, etc.

[0090] Similarly, the ratio of the area enclosed by the edges of the projection of the second magnetic field generating member 220 onto a plane perpendicular to its centerline to the area of ​​the second magnetic field generating member 220 onto a plane perpendicular to its centerline in the storage space 101 may be between 0.5 and 1.5, such as 0.5, 0.6, 0.7, 1, 1.5, etc.

[0091] The ratio of the projected area between the two magnetic field generating members and the storage space may be different.

[0092] Furthermore, since electromagnetic coils have hollow regions, the minimum requirement for their ratio must be greater than the minimum requirement for magnetic pieces.

[0093] As shown in Figure 23, taking the first magnetic field generating member 210 as an example, the first connection terminal 211 and the second connection terminal 212 of the first magnetic field generating member 210 are located in the same position. Specifically, the distance between the two connection terminals is less than 3 centimeters. This makes it easy to set the location of the power supply. The winding method of the second magnetic field generating member 220 is the same as that of the first magnetic field generating member 210, and the connection terminals of the first magnetic field generating member 210 and the second magnetic field generating member 220 are located in corresponding positions on both sides of the magnetic guide plate 230.

[0094] In one embodiment, the refrigerator includes a storage container according to any of the above embodiments, and the storage container provides magnetic field preservation for the food, thereby improving the freshness preservation effect of the food.
