As shown in fig. 1-3, in one embodiment, the storage container includes a storage body 100 and a magnetic field device 200. The storage body 100 is formed with a storage space 101. The magnetic field device 200 is disposed on an inner wall of the storage space 101 to generate a magnetic field in 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 magnetically permeable plate 230. The first magnetic field generating member 210 and the second magnetic field generating member 220 are disposed at both sides of the magnetic conductive plate 230, respectively.

Referring to fig. 1 to 3, in detail, the first and second magnetic field generating members 210 and 220 are magnetic sheets. The two magnetic sheets are respectively attached to both sides of the magnetic conductive plate 230, in other words, the two magnetic sheets clamp the magnetic conductive plate 230. The area of the installation surface of the magnetically permeable plate 230 on which the first magnetic field generating member 210 is installed 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 on the installation surface thereof can fall within the installation surface. The area of the installation surface of the magnetically permeable plate 230 on which the second magnetic field generating member 220 is installed 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 on the installation surface thereof can fall within the installation surface. The storage body 100 is a drawer with the opening facing upwards during use.

With continued reference to fig. 1-3, in one implementation of the present embodiment, the magnetic field device 200 is disposed at an inner bottom wall of the storage space 101. Since the magnetic sheet and the magnetically permeable plate 230 are both flat structures, the magnetic field device 200 as a whole can also be regarded as a flat structure. Therefore, it can be said that the magnetic field device 200 covers the inner bottom wall of the storage space 101 such that the side of the magnetic conductive plate 230 on which the first magnetic field generating member 210 is mounted faces the opening of the drawer and the side on which the second magnetic field generating member 220 is mounted faces the inner bottom wall of the drawer.

The magnetic conductive plate 230 may be provided with an opening facing the drawer on the side where the second magnetic field generating member 220 is mounted, and a bottom wall facing the drawer on the side where the first magnetic field generating member 210 is mounted. In addition, the magnetic field device 200 may be disposed on the inner side wall of the storage space 101, that is, the left side wall inner side, the right side wall inner side, the rear side wall inner side, and the front side wall inner side.

As shown in connection with fig. 1 and 4, in one implementation of the present embodiment, a magnetic field device 200 is provided at an outer bottom wall of the storage space 101 to generate a magnetic field in the storage space 101. In particular, it can also be said that the magnetic field device 200 covers the outer bottom wall of the drawer. Alternatively, the magnetic field device 200 may be directly secured to the outer bottom wall of the drawer. Alternatively, a concave plate with a groove may be provided, and the magnetic field device 200 is placed in the groove of the concave plate, and then the concave plate and the storage body 100 are fixed together, so that the magnetic field device 200 is fixed in a space defined by the groove and the outer bottom wall of the drawer.

In addition, the magnetic field device 200 may be disposed on the outer side wall of the drawer, that is, the outer side of the left side wall, the outer side of the right side wall, the outer side of the rear side wall, and the outer side of the front side wall.

In the solution of the present embodiment, the magnetic field device 200 is disposed in the interior or the exterior wall of the storage space 101, and the magnetic field device 200 includes a magnetic conductive plate 230, and a first magnetic field generating member 210 and a second magnetic field generating member 220 disposed at both sides of the magnetic conductive plate 230, respectively. In use, the energized first magnetic field generating member 210 and the second magnetic field generating member 220 are capable of generating a magnetic field that acts on the storage space 101, which in turn causes the magnetic field to act on the food material in the storage space 101. In the freezing process, the magnetic field can limit the free path of water molecules, so that hydrogen bonds in water molecular clusters are broken, the growth of crystal nuclei in the food material is inhibited, small ice crystals are generated in the food material, and the damage of the ice crystals to food material cells is reduced. Therefore, the method is beneficial to reducing the juice loss of the food materials after thawing, thereby reducing the nutrition loss of the food materials and ensuring the taste of the food materials.

During refrigeration, the magnetic field can reduce the supercooling degree of the food material, that is, under the application of the magnetic field, the food material can be kept in a non-frozen state at a lower temperature. In other words, the refrigerating temperature of the food materials can be reduced, so that bacterial breeding is further reduced, and the food materials are preserved.

In addition, the first magnetic field generating member 210 and the second magnetic field generating member 220 are respectively located at two sides of the magnetic conductive plate 230, so that the magnetic fields of the first magnetic field generating member 210 and the second magnetic field generating member 220 can be guided by the magnetic conductive plate 230, thereby making the distribution of the magnetic fields in the storage space 101 more uniform. Under the condition of lower cost, the optimal magnetic field fresh-keeping effect is realized.

Further, as shown in fig. 1, the two poles of the first magnetic field generating member 210 and the two poles of the second magnetic field generating member 220 are arranged in the same direction, and the two poles of the first magnetic field generating member 210 are arranged in a direction perpendicular to the surface of the magnetic conductive plate 230 on which the first magnetic field generating member 210 is mounted.

Referring to fig. 1, in detail, the N and S poles of the two magnetic sheets are distributed in the same direction and perpendicular to the surface of the magnetic sheet 230 on which the magnetic sheets are mounted. Illustratively, if the upper surface of the magnetic sheet above the magnetic conductive plate 230 is N-pole and the lower surface is S-pole, then the magnetic sheet below the magnetic conductive plate 230 is also N-pole and the lower surface is S-pole. Thereby enabling the magnetic fields of the first and second magnetic field generating members 210 and 220 to be superimposed, contributing to an increase in magnetic field strength.

In addition, it is preferable that the magnetic conductive plate 230 is made of a material having a relative magnetic permeability greater than 1, such as a ferromagnetic material or a permanent magnetic material. Wherein, the relative permeability represents the ratio of the permeability of the material to the vacuum permeability.

As shown in fig. 1 and 5, in one embodiment, the magnetic field device 200 is disposed in the storage space 101 with a space between the magnetic field device 200 and two opposite inner sidewalls of the storage space 101, and the magnetic conductive plate 230 is mounted with two sides of the first magnetic field generating member 210 and the second magnetic field generating member 220 facing the two opposite inner sidewalls of the storage space spaced from the magnetic field device 200, respectively.

Further, the storage container further 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 such that the magnetic field device 200 is disposed within the storage space 101.

Referring to fig. 1 and 5, in one implementation of the present embodiment, the support member 300 has a plate shape, and the support member 300 is provided with a receiving groove in which the magnetic field device 200 is disposed. Specifically, the plate-shaped supporting member 300 has one end in contact with the rear sidewall of the drawer and the other end in contact with the front sidewall of the drawer, thereby dividing the storage space 101 in the drawer into two parts distributed left and right. The support member 300 is formed with a receiving groove in which the magnetic field device 200 is disposed. In fig. 5, the magnetic field device 200 is shown in phantom to be seen in perspective.

Specifically, the thickness of the support member 300 is greater than the thickness of the magnetic field device 200, so that an accommodating groove having a thickness equal to or greater than the thickness of the magnetic field device 200 is hollowed out in the support member 300. The opening of the receiving slot is oriented towards the opening of the drawer such that the magnetic field device 200 can be inserted into the receiving slot directly from above the drawer opening such that the magnetic field device 200 is located within the storage space 101. The magnetic field device 200 is spaced from the storage space 101 by a distance between the left and right inner walls. The magnetic conductive plate 230 is installed with both side surfaces of the first magnetic field generating member 210 and the second magnetic field generating member 220 facing the left and right inner sidewalls of the storage space 101, respectively, that is, one magnetic sheet is located between the left sidewall of the storage space 101 and the magnetic conductive plate 230, and the other magnetic sheet is located between the right sidewall of the storage space 101 and the magnetic conductive plate 230.

In the solution of the present embodiment, the magnetic field device 200 is disposed in the storage space 101, and a space is formed between the magnetic field device 200 and two opposite inner side walls of the storage space 101. In view of the special structure of the magnetic field device 200, that is, the first magnetic field generating element 210 and the second magnetic field generating element 220 are respectively disposed at two sides of the magnetic conductive plate 230, after the magnetic field device 200 is disposed in the storage space 101, the magnetic conductive plate 230 can respectively guide and diverge the magnetic fields of the first magnetic field generating element 210 and the second magnetic field generating element 220 to the storage space 101 at two sides, so as to further improve the uniformity of the magnetic field distribution in the storage space 101, and facilitate improving the fresh-keeping effect of the food materials. And, it contributes to improving the magnetic uniformity efficiency of the magnetic conductive plate 230.

Further, by providing the receiving groove in the support member 300 so that the magnetic field device 200 can be disposed in the receiving groove, the magnetic field device 200 can be protected from the impact.

The supporting member 300 may be connected to the left and right side walls of the drawer, so as to divide the storage space 101 of the drawer into two parts that are disposed in front and rear directions. That is, the side surface of the magnetic plate 230 on which the first magnetic field generating member 210 is mounted may be perpendicular to the plane of the opening of the drawer.

In addition, the opening of the receiving groove of the support member 300 may also be directed toward the side wall of the drawer, that is, the opening of the receiving groove of the support member 300 is blocked by the side wall of the drawer after being assembled in place. Then, in assembly, it is necessary to put the magnetic field device 200 into the accommodating groove and then to assemble the whole of the magnetic field device 200 and the supporting member 300 into the storage space 101. Or, a hollow area corresponding to the opening of the receiving groove of the support member 300 is opened on the side wall of the drawer. Alternatively, the side wall of the drawer is recessed into the storage space 101 to form a slot, the notch of the receiving slot of the support member 300 corresponds to the notch of the slot, the support member 300 is inserted into the slot, and then the magnetic field device 200 is inserted into the receiving slot from the notch of the slot and the notch of the receiving slot.

As shown in fig. 1 and 6, in one implementation of the present embodiment, the support member 300 is a partition plate, and the magnetic field device 200 is disposed on a surface of the partition plate so as to be disposed in the storage space 101. Illustratively, the bulkhead interfaces with the front and rear interior side walls of the drawer, and the magnetic field device 200 is attached to the surface of the bulkhead facing the left interior side wall of the drawer or the surface of the bulkhead facing the right interior side wall of the drawer.

It should be noted that the support member 300 may be formed separately from the storage body 100, assembled at a later stage, or formed integrally. In the case that the support member 300 has the receiving groove, the side wall of the drawer may be recessed into the storage space 101 to form the receiving groove, so that the support member 300 is integrally formed on the drawer.

As shown in fig. 7 and 8, in one implementation of the present embodiment, 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 in the same direction from the surface of the base plate 310 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 disposed at the main support plate 320. The sidewall of the storage main body 100 is recessed into the storage space 101 to form an assembly groove, and the support member 300 assembled with the storage main body 100 is such that the main support plate 320 is inserted into the assembly groove. And the first sub-support plate 330 and the second sub-support plate 340 are respectively located outside two opposite outer sidewalls of the reservoir body 100.

Referring to fig. 7 and 8, in particular, the rear side wall and the bottom wall of the drawer are recessed into the storage space 101 to form an assembly groove, that is, the assembly groove has openings at the rear side and the bottom side of the drawer. The support member 300 to which the magnetic field device 200 is fixed may be assembled with the drawer from the rear to the front or from the bottom to the top so that the main support plate 320 is inserted into the assembly groove while the first and second sub support plates 330 and 340 are positioned outside the left and right sidewalls of the drawer, respectively.

In the solution of the present embodiment, by providing the base plate 310, the main support plate 320, the first sub support plate 330 and the second sub support plate 340 on the support member 300, when the support member 300 is assembled on the storage body 100, the assembly with the storage body 100 can be achieved by the 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 and the clamping action between the main support plate 320 and the first sub support plate 330 and the second sub support plate 340, without providing additional connection parts, which is beneficial to simplifying the assembly process between the storage body 100 and the support member 300.

It should be noted that the assembly of the support member 300 may be achieved by directly grooving the rear side wall and the bottom wall of the drawer.

It should also be noted that, because the drawer is a storage body that needs to be movable when in use, the two walls of the drawer need to be adjusted to fit the support members. For a stationary storage body, only the side walls of the storage body 100 facing the opening thereof need be recessed into the storage space 101 to form an assembly slot.

As shown in fig. 9, further, the storage container further includes two magnetic field members 400, and the two magnetic field members 400 are respectively disposed at the inner side or the outer side of the two opposite sidewalls of the storage space 101 where the first magnetic field generating part 210 and the second magnetic field generating part 220 are respectively installed on the magnetic conductive plate 230.

Specifically, the magnetic conductive plate 230 is mounted with both side surfaces of the first and second magnetic field generating members 210 and 220 facing the left and right sidewalls of the storage space 101, respectively, and the two magnetic field members 400 are mounted at the outer sides of the left and right sidewalls of the drawer, respectively. Wherein, the magnetic field member 400 includes a magnetic member and a shim plate, and the magnetic member and the shim plate are disposed in a bonded manner, thereby forming an overall plate-like structure. For example, the magnetic member may be a magnetic sheet or a coil that is energized to produce a magnetic field. In addition, the magnetic field member 400 may include only a magnetic member.

It should be noted that the magnetic field member 400 may be disposed on an inner sidewall of the drawer.

In addition, when the magnetic conductive plate 230 is mounted with both side surfaces of the first and second magnetic field generating members 210 and 220 facing the front and rear sidewalls of the storage space 101, respectively, the two magnetic field members 400 are mounted on the outer or inner sides of the front and rear sidewalls of the drawer, respectively.

In the solution of the present embodiment, the magnetic field members 400 are disposed on the inner side or the outer side of the two opposite side walls of the storage space 101, where the two side surfaces of the first magnetic field generating element 210 and the second magnetic field generating element 220 are respectively installed on the magnetic conductive plate 230, so as to help to enhance the magnetic field intensity in the storage space 101 and further improve the uniformity of the magnetic field distribution in the storage space 101.

It should be noted that, in the case where the magnetic field device 200 is disposed on the support member 300 and the support member 300 is provided with the main support plate 320, the first sub-support plate 330 and the second sub-support plate 340, the magnetic field member 400 may be disposed on the sidewall of the memory body 100 or may be disposed on the first sub-support plate 330 and the second sub-support plate 340. Alternatively, mounting grooves are provided in the first sub-support plate 330 and the second sub-support plate 340, and the magnetic field members are provided in the mounting grooves.

Specifically, the magnetic field device 200 has a space between the upper and lower opposing inner side walls of the liner. The magnetic conductive plate 230 is installed with both side surfaces of the first and second magnetic field generating members 210 and 220 facing the upper and lower inner sidewalls of the inner container, respectively.

It should be noted that, the storage space 101 defined by the liner may be a refrigerating chamber, a temperature changing chamber or a freezing chamber.
