Detailed Description

FIG. 1 is a schematic perspective view of a refrigerator 10 having a fresh food storage container 200 according to one embodiment of the present invention. The refrigerator 10 of the present embodiment may generally include a cabinet 120, a door 110, and a refrigeration system (not shown in the drawings). The housing 120 may define at least one storage compartment, typically a plurality of storage compartments, with an open front side, such as a refrigerated storage compartment, a frozen storage compartment, a temperature-variable storage compartment, and the like. The number and function of the specific storage compartments can be configured according to pre-determined requirements.

The refrigerator 10 of the present embodiment may be an air-cooled refrigerator, in which an air path system is disposed in the cabinet 120, and a fan sends a cooling air flow, which is heat-exchanged by a heat exchanger (evaporator), to the storage compartment through the air supply opening, and then returns to the air duct through the air return opening. And refrigeration is realized. Since the refrigerator body 120, the door 110, and the refrigeration system themselves are well known and easily implemented by those skilled in the art, the details of the refrigerator body 120, the door 110, and the refrigeration system themselves are not described below in order to avoid covering and obscuring the utility model points of the present application.

A fresh food storage container 200 may be disposed within one or more of the storage compartments of the refrigerator 10. When being placed in a freezing storage chamber, the fresh-keeping storage container 200 can be used for freezing and keeping fresh of frozen food materials, inhibiting the growth of ice crystal nuclei, ensuring that the growth rate of the ice crystals is higher than the migration rate of water molecules, and the generated ice crystals are small, thereby reducing the damage to cells, avoiding the loss of juice, accelerating the freezing process and shortening the freezing time. When the fresh-keeping storage container 200 is used for refrigerating a storage chamber, the oxidation-reduction reaction speed of food materials can be reduced, the loss of nutrition and moisture is reduced, the food materials are prevented from changing color, the breeding of bacteria is inhibited, and the fresh-keeping period of the food materials is prolonged.

The number of fresh-keeping storage containers 200 and the types of storage compartments that can be arranged can be configured according to the needs of the user. For example, one or more fresh food containers 200 may be disposed within the refrigerator 10. The fresh-keeping storage container 200 may be disposed in a refrigerating storage compartment, a freezing storage compartment, or a variable-temperature storage compartment, and magnetic field-assisted fresh keeping is performed in the storage compartments. The fresh food container 200 may also be used as an independent compartment of the refrigerator 10, and the temperature of the fresh food container is controlled independently by the refrigerator 10. For example, the refrigerator 10 is specially constructed to arrange the compartments of the fresh food container 200 or the fresh food container 200 is directly constructed as the compartment of the refrigerator 10.

FIG. 2 is a schematic view of a fresh food storage container 200 for a refrigerator according to one embodiment of the present invention; fig. 3 is an exploded view of the fresh food storage container 200 shown in fig. 2. The fresh food storage container 200 may include a storage box 210 and a permanent magnet plate 221. The storage box 210 defines a storage space for placing stored objects therein, and the storage box 210 may have a box shape. In some embodiments, the storage box 210 may have a generally flat rectangular parallelepiped shape (i.e., the distance in the height direction is significantly less than the distance in the depth direction and the distance in the lateral left-right direction). Those skilled in the art may configure the storage box 210 according to the configuration and size of the storage space, and may use a box-shaped, or drawer configuration.

The two permanent magnet plates 221 are respectively disposed on a set of sidewalls of the storage box 210. The shape of the permanent magnet plate is matched with the shape of the side wall of the storage box where the permanent magnet plate is located. For example, for a rectangular storage box, the permanent magnet plate 221 may be rectangular corresponding to the side wall.

The two permanent magnet plates 221 may be selectively placed on the left and right sides, the top and bottom sides, or the front and rear sides of the storage box 210 according to the shape of the storage box 210. In the case where the storage box 210 has a flat shape as a whole, particularly, in the case where the storage box has a drawer structure, the two permanent magnet plates 221 may be preferably disposed at the top and bottom of the storage box 210. By the arrangement mode, the distance between the two permanent magnet plates 221 can be reduced, and the magnetic field intensity and uniformity are improved.

The two permanent magnet plates 221 have the same magnetic field direction and are respectively perpendicular to the side wall to form a magnetic field penetrating through the storage space, and the magnetic field intensity range of the magnetic field is 1-200 Gs. When the magnetic field intensity is applied to a freezing environment, the magnetic field intensity can be preferably 5-60 GS, for example, about 20Gs can be selected; in the case of application to a refrigeration environment, the magnetic field intensity can be 20-160 GS, preferably 40-80 Gs, such as about 60 Gs. In the embodiment in which the two permanent magnet plates 221 are disposed at the top and the bottom of the storage box 210, the N poles of the two permanent magnet plates 221 may be both disposed upward and the S poles may be disposed downward, so as to form a magnetic field penetrating through the storage space from bottom to top as shown in fig. 2. Based on the same technical idea, those skilled in the art can easily implement magnetic fields in opposite directions by adjusting the magnetic pole directions, that is, the S poles of the two permanent magnet plates 221 are set to be upward, so as to implement a magnetic field from bottom to top. The permanent magnetic field formed by the permanent magnetic plate 221 is a static magnetic field, so that the storage space can always have a magnetic field with a certain strength.

Through a large number of verifications, the magnetic field within the magnetic field intensity range can effectively improve the storage quality of the stored objects and achieve the expected fresh-keeping effect.

The permanent magnet plate 221 should ensure that a uniform magnetic field is formed at all positions of the storage space. That is, the storage space is positioned in the magnetic field range without dead angles. In some embodiments, the projection of the storage space on the plane of the permanent magnet plate 221 is located within the peripheral outline of the permanent magnet plate, that is, the permanent magnet plate 221 may have a side surface corresponding to the storage space that is substantially the same as or slightly larger than the area of the side surface. For example, the permanent magnet plate 221 positioned at the top of the storage box 210 can cover the top region of the storage space, and the permanent magnet plate 221 positioned at the bottom of the storage box 210 can cover the bottom region of the storage space.

FIG. 4 is a schematic view of a fresh food storage container 200 for a refrigerator according to another embodiment of the present invention; fig. 5 is an exploded view of the fresh food storage container 200 shown in fig. 4. The fresh-keeping storage container 200 in this embodiment is further provided with a uniform magnetic plate 222. The uniform magnetic plate 222 is disposed adjacent to a side of the permanent magnetic plate 221 facing away from the storage box 210.

The shim plate 222 may be made of a material having a low coercive force and a high magnetic permeability, and for example, a silicon steel sheet or the like may be used. The two uniform magnetic plates 222 are respectively arranged on the outer sides of the permanent magnetic plates 221. For example, the top magnet homogenizing plate 222 is disposed above the top permanent magnet plate 221, and the bottom magnet homogenizing plate 222 is disposed below the bottom permanent magnet plate 221. One side plate surface of the even magnetic plate 222 can be arranged to abut against the corresponding permanent magnetic plate 221 so as to facilitate magnetic field conduction. In some embodiments, the shim plate 222 and the permanent magnet plate 221 may be fixed by welding or bonding.

The permanent magnet plate 221 may have a side surface size substantially the same as or slightly larger than the side surface area corresponding to the storage space. After the uniform magnetic plate 222 is provided, the size of the permanent magnetic plate 221 can be reduced. The uniform magnetic plate 222 changes the magnetic field distribution of the permanent magnetic plate 221 to be more uniform. In some embodiments, the permanent magnet plate 221 may be smaller than the corresponding sidewall of the storage box 210, and the projection of the storage space on the plane of the magnetism homogenizing plate 222 is located within the periphery of the magnetism homogenizing plate 222. That is, the size of the permanent magnet plate 221 can be small, and the coverage area of the magnetic field is enlarged by the shim plate 222. The uniform magnetic plate 222 can be substantially the same size with the side corresponding to the storage space or slightly larger than the area of the side. For example, the shim plate 222 at the top of the magazine 210 can cover a top region of the storage space, while the shim plate 222 at the bottom of the magazine 210 can cover a bottom region of the storage space.

The centers of the permanent magnet plate 221 and the uniform magnet plate 222 arranged on the same side are opposite to the center of the side wall of the storage box 210 where the permanent magnet plate and the uniform magnet plate are arranged. Namely, the top permanent magnet plate 221 and the uniform magnet plate 222 are arranged concentrically with the top of the storage space, and the bottom permanent magnet plate 221 and the uniform magnet plate 22 are arranged concentrically with the bottom of the storage space. The magnetic field range of the permanent magnet plate 221 can be expanded by using the large uniform magnet plate 222 with a large size, so that the storage space is positioned in the magnetic field range without dead angles.

In addition, the usage amount of magnetic materials can be reduced by using the even magnetic plate 222, and the cost of the fresh-keeping storage container 200 is reduced. The ratio of the area of the permanent magnet plate 221 to the projection area of the storage space on the plane of the permanent magnet plate 221 is in a range of 30% to 98%, and in some preferred embodiments, the ratio may be in a range of 50% to 95%. That is, the area of the top permanent magnet plate 221 is 30% to 98% (e.g., 50% to 95%) of the area of the top region of the storage space and is located at the center of the top surface of the storage space; the area of the bottom permanent magnet plate 221 is 30% to 98% (e.g., 50% to 95%) of the area of the bottom region of the storage space and is located at the center of the bottom surface of the storage space. The area ratio is actually verified, so that the distribution of the magnetic field in the whole storage space can be realized through the magnetism homogenizing plate 222, and the magnetic field intensity can meet the set requirement.

Based on the above-mentioned structure of the permanent magnet plate 221 and the storage box 210 shown in fig. 2 to 5 and the above description, the permanent magnet plate 221 can be arranged left and right or front and back.

Fig. 6 is a schematic view of a fresh food storage container 200 for a refrigerator according to still another embodiment of the present invention. In this embodiment, the two permanent magnet plates 221 are disposed on the left and right, one of which is disposed on the right side of the storage box 210, and the other of which is disposed on the left side of the storage box 210. The magnetic poles of the two permanent magnet plates 221 are arranged towards the left side, so that the magnetic field direction from right to left can be realized. Based on the same technical idea, those skilled in the art can easily realize the magnetic fields in opposite directions by adjusting the magnetic pole directions, that is, the magnetic fields from left to right.

The left and right permanent magnet plates 221 can also be further provided with a uniform magnet plate, so that the size of the permanent magnet plates 221 is reduced, the distribution of a magnetic field is changed by using the uniform magnet plate, and the storage space is positioned in the magnetic field range without dead angles.

In the fresh-keeping storage container 200 without the uniform magnetic plate, the area of the permanent magnetic plate 221 can be increased to realize the distribution of the magnetic field without dead angles, that is, the permanent magnetic plate 221 positioned on the left side of the storage box 210 can cover the left side of the storage space, and the permanent magnetic plate 221 positioned on the right side of the storage box 210 can cover the right side of the storage space. After the uniform magnetic plate is arranged, the left side of the storage space is covered by the uniform magnetic plate on the left side; and the right side of the storage space is covered by the right uniform magnetic plate.

FIG. 7 is a schematic view of a fresh food storage container 200 of a drawer configuration according to one embodiment of the present invention. The storage box 210 of the fresh-keeping storage container 200 may include: a cylinder 211 and a drawer 212. Wherein the cylinder 211 has a forward opening. Drawer 212 is retractably disposed within barrel 211. The storage box 210 can be pulled out to expose the storage space 213 for the storage of the stored objects. After the drawer 212 is pushed into the cylinder 211, a separate sealed space can be formed.

The two permanent magnet plates 221 may be disposed above and below the cylinder 211, i.e., outside the top wall and outside the bottom wall of the cylinder 211, respectively. In some embodiments, the top permanent magnet plate 221 may be disposed against the top wall of the cylinder 211, and the bottom permanent magnet plate 221 may be disposed against the bottom of the cylinder 211. Considering that the drawer 212 has guide rails and the like on both sides and an opening on the front side, the distance between the permanent magnet plate 221 and the stored object can be reduced by disposing the permanent magnet plate 221 on the top and bottom of the cylinder 211, respectively, and the effective utilization rate of the magnetic field can be improved. The fresh food storage container 200 of the drawer structure has little influence on the storage space 213 of the drawer 212 itself.

Alternatively, the permanent magnet plate 221 in the above embodiment may be reduced in size, and a uniform magnet plate covering the corresponding side surface of the storage space 213 may be added on the outer side. The storage space 213 is uniformly covered with a magnetic field by the uniform magnetic plate.

Fig. 8 is a schematic view of a fresh food storage container 200 of a drawer structure according to another embodiment of the present invention. In this embodiment, two permanent magnet plates 221 are respectively disposed on the inner side of the top wall of the cylinder body 211 and the inner side of the bottom wall of the cylinder body 211. That is, the permanent magnet plate 221 is disposed in the cylinder 211. The permanent magnet plate 221 may be fixed on the inner wall of the cylinder 211, so as to further reduce the distance between the permanent magnet plate 221 and the stored object and improve the effective utilization rate of the magnetic field.

Alternatively, a uniform magnetic plate covering the corresponding side surface of the storage space 213 can be additionally arranged between the permanent magnetic plate 221 and the cylinder body 211. The uniform magnetic plate is used to make the magnetic field uniformly distributed in the storage space 213.

Fig. 9 is a schematic view of an air supply structure in the fresh food storage container 200 of a drawer structure according to an embodiment of the present invention. The fresh-keeping storage container 200 realizes internal refrigeration through air cooling, and further includes: an air intake duct assembly 214, and an air return opening 215. The air inlet duct assembly 214 is configured to supply a flow of refrigerant air into the drum 211, and the air return opening 215 is opened in the drum 211 to discharge air from the drum 211. In fig. 9, the permanent magnet plate 221 is covered by a cover plate outside the cylindrical body 211, which is not shown.

The air inlet duct assembly 214 is used for connecting a refrigeration air duct of the refrigerator 10, and introduces low-temperature air flow which is subjected to heat exchange by the evaporator in the refrigeration air duct into the cylinder 211. In some embodiments, the cooling air duct may enter the top of the storage box 210, and may be sent out from the air return opening 215 after heat exchange. In the present embodiment, the air inlet duct assembly 214 and the air return opening 215 are disposed at the rear side of the fresh food container 200, and the specific positions thereof can be configured according to the air duct position and the refrigeration system structure in the refrigerator 10. The air cooling system can ensure that the storage space 213 is stabilized within a set temperature range, and the magnetic field preservation function of the stored objects is realized by matching the action of the magnetic field.

The fresh-keeping storage container for the refrigerator of the above embodiment forms a magnetic field, 1 to 200Gs, penetrating through the storage space in the storage box 210 by using the two permanent magnet plates 221. When the magnetic field intensity is applied to a freezing environment, the magnetic field intensity can be preferably 5-60 GS, for example, about 20Gs can be selected; in the case of application to a refrigeration environment, the magnetic field intensity can be 20-160 GS, preferably 40-80 Gs, such as about 60 Gs. The permanent magnetic field formed by the permanent magnetic plate 221 is more stable, and the influence of the heating of the electromagnetic element on the storage quality is avoided. By optimizing the structures of the uniform magnetic plate 222 and the permanent magnetic plate 221, the fresh-keeping storage container 200 has a more compact structure, and is particularly suitable for a storage drawer. The magnetic field is helpful for improving the storage quality, shortening the freezing time, reducing the juice loss rate and the nutrition loss of food, well reducing the low-temperature damage to cells, tissues and other biological products in the freezing process, better preserving the functions and the forms of the cells, reducing the number of microorganisms and bacteria and prolonging the preservation period.
