Detailed Description
FIG. 1 is a schematic perspective view of a refrigerator 10 having a magnetic field 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 with an open front side, and typically a plurality of storage compartments, such as a refrigerating storage compartment, a freezing storage compartment, a temperature-changing 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 invention points of the present application.
A magnetic field freshness retaining storage container 200 may be disposed inside one or more storage compartments of the refrigerator 10. When the magnetic field preservation storage container 200 is placed in a freezing storage chamber, the magnetic field preservation storage container can be used for freezing and preserving frozen food materials, inhibiting the growth of ice crystal nuclei, enabling the growth rate of the ice crystals to be higher than the migration rate of water molecules, and enabling the generated ice crystals to be smaller, so that damage to cells is reduced, juice loss is avoided, the freezing process is accelerated, and the freezing time is shortened. When the magnetic field preservation storage container 200 is placed in a cold 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 discoloring, the breeding of bacteria is inhibited, and the preservation period of the food materials is prolonged.
The number of the magnetic field freshness retaining storage containers 200 and the storage compartments arranged therein may be configured according to the user's needs. For example, one or more magnetic field fresh food containers 200 may be disposed within the refrigerator 10. The magnetic field freshness retaining storage container 200 may be disposed in a refrigerating storage compartment, a freezing storage compartment, or a temperature-changing storage compartment, and magnetic field-assisted freshness retaining is performed in the storage compartments. The magnetic field freshness retaining storage container 200 may also be used as an independent compartment of the refrigerator 10, and the refrigerator 10 controls the temperature of the independent compartment independently.
FIG. 2 is a schematic view of a magnetic field crisper container 200 according to one embodiment of the present invention as a refrigerator drawer.
The magnetic freshness storage container 200 may generally comprise: a storage box 210, one or more magnetically permeable bands 230, and a plurality of magnetic members 220. The storage box 210 defines a storage space 212 for storing stored objects therein, and the storage box 210 may have a box shape. In some embodiments, the storage box 210 may be a rectangular parallelepiped shape that is generally flat (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). The storage box 210 may have a drawer structure.
The magnetic freshness storage container 200 may further include a barrel 211. The cylinder 211 has a forward opening. The storage box 210 is a drawer and is drawably disposed in the cylinder 211. The storage box 210 has a top opening for taking and placing articles, and the top opening is exposed after being pulled out of the cylinder 211. After the storage box 210 is pushed into the cylinder 211, an independent storage space 212 can be formed. The storage box 210 has a front end cap 214, the front end cap 214 abuts against a frame body at the front end of the cylinder body 211, and a sealing structure can be arranged between the front end cap 214 and the cylinder body 211, so that the storage space 212 is relatively sealed. The magnetic field freshness retaining storage container 200 may further be provided with an air supply outlet and an air return outlet (not shown in the figure) for introducing an external refrigerating airflow into the magnetic field freshness retaining storage container 200, and returning the external refrigerating airflow to the outside of the storage box 210 after heat exchange. The positions of the supply air outlet and the return air inlet may be set according to the configurations of the supply air duct, the return air duct, and the storage compartment of the refrigerator 10. Since the structure of the drawer inside the refrigerator and the cooling method are known to those skilled in the art, the following description of the present embodiment is not repeated.
One or more magnetic conduction ring belts 230 are respectively sleeved on the periphery of the storage box 210. The magnetic conductive ring band 230 may be surrounded along the upper, lower, left, and right sides of the storage box 210, that is, along the longitudinal direction of the storage box 210. Alternatively, the magnetic conductive endless belt 230 may also be wound around the front, rear, left, and right sides of the storage box 210, that is, around the storage box 210 in the transverse direction. For a structure in which the magazine 210 is flat in shape as a whole, particularly in the case where the magazine 210 is in the form of a drawer, the magnetically permeable annulus 230 may be looped along the longitudinal direction of the magazine 210. In the case where a plurality of magnetically conductive annular bands 230 are arranged, the plurality of magnetically conductive annular bands 230 may be disposed at intervals, thereby forming a plurality of magnetically conductive loops and making the magnetic field distribution more uniform.
The magnetic conductive ring band 230 may be made of a material with low coercive force and high magnetic permeability, and the formed magnetic conductive path may be used to gather a magnetic field, reduce the release of the magnetic field to the outside, and reduce interference with other components outside the storage box 210 (e.g., avoid magnetizing the other components). The magnetically permeable annulus 230 may be made of a sheet of silicon steel or similar material. The size of the magnetically permeable annulus 230 may be determined by testing the magnetic field distribution to meet the conditions for focusing the magnetic field. In some embodiments, the width of the magnetically permeable annulus 230 may be between one-half and one-tenth of the overall length of the storage compartment 210. For example, in the embodiment where the magnetic conductive ring band 230 surrounds along the longitudinal direction of the storage box 210, the width of the magnetic conductive ring band 230 along the front-back depth direction may be one-half to one-tenth of the length of the storage box 210 along the front-back depth direction; for another example, in the embodiment where the magnetic conductive endless belt 230 is looped along the longitudinal direction of the storage box 210, the width of the magnetic conductive endless belt 230 along the vertical height direction may be one half to one tenth of the length of the storage box 210 along the vertical height direction.
In the embodiment where the magnetic conductive ring band 230 surrounds along the longitudinal direction of the storage box 210, a plurality of magnetic conductive ring bands 230 may be arranged at intervals along the front-rear depth direction of the storage box 210. If there is one magnetic conduction ring belt 230, the magnetic conduction ring belt 230 may be disposed in the middle region of the storage box 210 in the front-rear depth direction, and is opposite to the middle region of the two magnetic members 220 in the front-rear depth direction. The number and specific location of the magnetically permeable annuli 230 may be set according to the range and strength of the magnetic field. For the storage box 210 with a smaller storage space 212, a magnetic conduction ring belt 230 can be arranged in the middle; for the storage box 210 with a larger storage space 212, a plurality of magnetic conduction ring belts 230 can be arranged at intervals.
Compared with the shielding device arranged at the periphery of the magnetic field and surrounding the periphery of the storage box 210, the magnetic preservation storage container 200 of the embodiment utilizes the smaller magnetic conduction ring band 230 to realize a magnetic conduction path, so that the use of magnetic conduction materials can be reduced under the condition of meeting the requirement of the magnetic field intensity, the cost of the magnetic preservation storage container 200 can be saved, and the weight of the magnetic preservation storage container 200 and the whole refrigerator 10 can be reduced.
The plurality of magnetic members 220 are respectively disposed between the storage box 210 and the one or more magnetic conductive ring bands 230, and are configured to form a magnetic field in the storage space 212, and form an annular magnetic conductive path outside the storage space 212 by using the one or more magnetic conductive ring bands 230. The magnetic member 220 serves as a generation source of a magnetic field. The magnetic member 220 may have a plate shape and be disposed opposite to a case wall of the storage case 210. The magnetic conductive ring band 230 is disposed around the outside of the magnetic member 220.
In some embodiments, the magnetic conductive annulus 230 may have a portion that abuts the magnetic member 220 to focus the magnetic field away from the storage space 212 to complete the closure of the magnetic field.
The number of the magnetic members 220 may be two, and the two magnetic members are respectively disposed on a set of opposite sides of the storage space 212, and are particularly suitable for the rectangular storage space 212. The opposite sides of the two magnetic members 220 can be selected according to the shape of the storage box 210 and the position in the refrigerator 10, and can be selectively placed on the lateral sides, the top and bottom sides, or the front and back sides of the storage box 210. In the case that the magnetically conductive endless belt 230 is looped along the upper, lower, left, and right sides of the storage box 210, the magnetic members 220 are respectively disposed on the top and bottom surfaces of the storage box 210 or the magnetic members 220 are respectively disposed on the lateral left side surface or the lateral right side surface of the storage box 210.
The shape of each magnetic member 220 is substantially identical to the shape of the side surface on which the magnetic member is disposed, so that the magnetic field can uniformly cover the storage space 212. In some embodiments, the projection of the storage space 212 on the plane of the magnetic member 220 may be located within the outer contour of the magnetic member 220. That is, the magnetic members 220 may be equal to or slightly larger than the corresponding sides of the storage assembly 210. In the case that the magnetic members 220 are disposed at the top and bottom of the storage box 210, the top magnetic members 220 may cover the top surfaces of the storage spaces 212, respectively; and the bottom magnetic member 220 cover the bottom surface of the storage space 212, respectively.
The magnetic member 220 may use either a permanent magnetic member or an electromagnetic member. FIG. 3 is a schematic view of a magnetic member 220 of a magnetic field fresh food storage container 200 according to one embodiment of the present invention. In this embodiment, the magnetic member 220 includes an electromagnetic coil 221. The electromagnetic coil 221 is wound with an electromagnetic coil along the circumferential direction, and the electromagnetic coil forms an electromagnetic field in the storage space after being electrified. The electromagnetic coil 221 may be formed in a flat ring shape, with the top and bottom being planar and having a thickness significantly less than the outer peripheral dimension. The width-to-thickness ratio of the electromagnetic coil 221 may be set to a range of 1-10. The electromagnetic ring 221 with the above structure can be more conveniently matched with the storage box 210 and the magnetic conduction ring belt 230, and occupies a smaller space. The electromagnetic ring 221 has a corresponding waterproof structure, for example, an electromagnetic coil that is protected inside by a dip coating, a plastic encapsulation, a sealing ring or a sealing housing, and is configured as a flat ring as a whole.
Through the control of the electromagnetic coil, the electromagnetic field can be set as a static magnetic field with constant magnetic field direction and/or magnetic field strength, an alternating magnetic field with alternating magnetic field direction and/or magnetic field strength, and a pulse magnetic field started at intervals according to requirements. The adjustment of the magnetic field may be achieved by adjusting the current to the electromagnetic coil. In some embodiments, the electromagnetic field may be adjusted according to the storage environment in the storage space 212 and the storage state of the stored objects.
Fig. 4 is a schematic view of a magnetic member 220 of a magnetic field fresh food storage container 200 according to another embodiment of the present invention. The magnetic member 220 may include both a permanent magnetic component 222 and an electromagnetic component 221 (e.g., an electromagnetic coil), the permanent magnetic component 222 provides a basic permanent magnetic field, and the electromagnetic component 221 is energized to form an electromagnetic field superimposed with the permanent magnetic field. The intensity range of the magnetic field can be set to be 1Gs-100Gs, and in the case of being applied to a freezing environment, the magnetic field intensity range can be preferably 5-60 GS, for example, about 20Gs can be selected; in the case of application to a refrigerated environment, the magnetic field strength may range from 20 to 160GS, preferably from 40 to 80Gs, for example around 60 Gs. The permanent magnet part 222 may be a permanent magnet plate 222. That is, each magnetic member 220 includes an electromagnetic ring 221 and a permanent magnet plate 222, and an electromagnetic coil is wound around the electromagnetic ring 221 along a ring circumference direction and forms an electromagnetic field after being electrified. The permanent magnet plate 222 is disposed at a central through hole of the electromagnetic coil 221 or disposed adjacent to the electromagnetic coil 221, and is configured to generate a permanent magnetic field in accordance with a direction of the electromagnetic field.
The permanent magnet plate 222 may make the electromagnetic field more uniform, in addition to providing a permanent magnetic field. The electromagnetic coil 221 and the permanent magnet plate 222 are concentrically disposed. The permanent magnet plate 222 may have a size larger than the outer circumferential profile of the electromagnetic coil 221, thereby enlarging the coverage of the electromagnetic field. The permanent magnetic field formed by the permanent magnetic plate 222 is a static magnetic field, so that the storage space 212 always has a magnetic field with a certain strength.
The number of turns of the electromagnetic coil in the electromagnetic coil 221 can be set according to the required magnetic field strength. The direction of the electromagnetic field formed by the electromagnetic coil 221 may be set to coincide with the direction of the permanent magnetic field of the permanent magnetic plate 222. In this embodiment, the permanent magnet plate 222 may also diffuse the range of the electromagnetic field, improving the uniformity of the magnetic field in the storage space.
Through the control of the electromagnetic coil, the electromagnetic field can also be set to be a static magnetic field with constant magnetic field direction and/or magnetic field strength, an alternating magnetic field with alternating magnetic field direction and/or magnetic field strength, and a pulse magnetic field started at intervals according to requirements. The adjustment of the magnetic field may be achieved by adjusting the current to the electromagnetic coil. In some embodiments, the electromagnetic field may be adjusted according to the storage environment in the storage space and the storage state of the stored object. The basic magnetic field strength is maintained by the permanent magnetic field of the permanent magnetic plate 222 without the electromagnetic field being activated.
The direction of the electromagnetic field can be set to be consistent with that of the permanent magnetic field, so that the mutual superposition of the magnetic fields is realized, and the magnetic field intensity is improved. In the case that the magnetic member 220 is disposed at the top and bottom of the storage space as shown in fig. 2, the magnetic field direction in the storage space 212 may be from top to bottom or from bottom to top. It is easy for a person skilled in the art to achieve a magnetic field of opposite direction by changing the pole direction.

That is, the barrel 211 can prevent the electromagnetic ring 221 from generating heat to affect the stored object to some extent, and is also convenient for dissipating heat from the electromagnetic ring 221.
Alternatively, the magnetic member 220 and the magnetic conductive ring band 230 may be disposed inside the cylinder 211, for example, the magnetic conductive ring band 230 may be disposed inside the cylinder 211, and the magnetic member 220 may be disposed inside.

The two magnetic conductive ring belts 230 respectively encircle the upper, the lower, the left and the right of the cylinder 211. One of the magnetic conductive ring bands 230 is disposed forward and the other magnetic conductive ring band 230 is disposed rearward. The outer magnetic field near the front of the storage box 210 is gathered by the front magnetic conductive ring band 230, so that the magnetic field at the front of the storage box 210 is closed. The outer magnetic field near the rear of the storage box 210 is gathered by the magnetic conductive ring band 230 near the rear, so that the magnetic field at the rear of the storage box 210 is closed. The two magnetic conduction ring belts 230 can disperse the magnetic field, so that the magnetic field in the storage space is more uniform, and the magnetic field intensity in the central area is prevented from being obviously higher than that in the surrounding area.

The refrigerator 10 of this embodiment can also combine magnetic field control with refrigeration control, so as to ensure that food is frozen in a magnetic field environment, thereby achieving the effect of fresh-keeping and freezing.
The refrigerator 10 may further optionally include one or more of a storage temperature sensor 330, an opening/closing detector 340, and a 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/close state of the storage space.
After the open/close detector 340 detects that the storage space is opened, whether new food materials are put in or whether the original food materials need to be frozen again can be detected through the storage temperature sensor 330.
