The magnetic field preservation storage container of the embodiment forms a magnetic field for preservation in the internal preservation storage space by arranging the magnetic field device. Fig. 1 is a schematic diagram of a magnetic field device 410 in a magnetic field preservation container according to one embodiment of the utility model. Fig. 2 is an exploded view of the components of the magnetic field device 410 shown in fig. 1.

The magnetic field device 410 may include a first magnetic field assembly 411 and a second magnetic field assembly 421 disposed opposite each other. The first magnetic field assembly 411 and the second magnetic field assembly 421 may be of substantially identical construction, for example, the first magnetic field assembly 411 may include a first magnetic source sheet 414, a first magnetic permeable plate 413; correspondingly, the second magnetic field assembly 421 may include a second magnetic source sheet 424 and a second magnetic conductive plate 423. In some embodiments, the first magnetic field assembly 411 may be further provided with a first electromagnetic coil 415; a second electromagnetic coil 425 may also be provided in the second magnetic field assembly 421. The first magnetic source sheet 414 is attached to the central region of the first magnetic conductive plate 413, and the second magnetic source sheet 424 is attached to the central region of the second magnetic conductive plate 423.

The first magnetic source sheet 414 and the second magnetic source sheet 424 may be uniformly magnetized permanent magnetic sheets, which may be made of permanent magnetic materials having a certain flexibility in consideration of cooperation with the first magnetic conductive plate 413 and the second magnetic conductive plate 423, for example, rubber magnetic sheets having flexibility, which are made by compounding bonded ferrite magnetic powder with synthetic rubber, may be used.

The magnetization requirements of the first magnetic source sheet 414 and the second magnetic source sheet 424 satisfy the above-mentioned effective magnetic field strength range of 10GS-100GS (1-10 mT) formed in the fresh storage space, and further may be set to 20-80GS, for example, 10GS, 20GS, 40GS, 60GS, 80GS, 100GS, etc., and the effective magnetic field spacing range is: 60-240mm, i.e. the magnetic field may reach the above strength requirements in a distance range of 60mm to 240mm from the magnetic source component. The magnetic field directions of the first magnetic source piece 414 and the second magnetic source piece 424 are respectively perpendicular to the surfaces of the first magnetic source piece 414 and the second magnetic source piece 424, and the opposite magnetic poles of the first magnetic source piece 414 and the second magnetic source piece 424 are opposite magnetic poles, so that the uniformity of the magnetic field in the fresh-keeping storage space can be further ensured.

The first and second magnetic conductive plates 413 and 423 are made of a material having a low coercive force and a high magnetic permeability. Wherein the area of the first magnetic conductive plate 413 may be slightly larger than the first magnetic source piece 414, and the area of the second magnetic conductive plate 423 may be slightly larger than the second magnetic source piece 424. The first magnetic conduction plate 413 is matched with the first magnetic source piece 414, the second magnetic conduction plate 423 is matched with the second magnetic source piece 424, so that close fit can be realized, zero clearance fit is realized, and the uniformity of a magnetic field is improved.

At least one magnetic field connection 431 is used to connect the first magnetic field assembly 411 and the second magnetic field assembly 421. The magnetic field connection member 431 may be made of the same material as the first and second magnetic conductive plates 413 and 423. The magnetic field connection 431 may be two or more, for example, the magnetic field connection 431 may be connected to the first magnetic field assembly 411 and the second magnetic field assembly 421 from one or more directions around the first magnetic field assembly 411 and the second magnetic field assembly 421.

The first magnetic field component 411 and the second magnetic field component 421 are oppositely arranged, and basically the same structure is adopted, through testing, the first magnetic conduction plate 413 can adjust the magnetic field distribution of the first magnetic source piece 414, and the second magnetic conduction plate 423 can adjust the magnetic field distribution of the second magnetic source piece 424, so that the magnetic field is more uniform and the coverage range of the magnetic field is enlarged. The magnetic field connecting piece 431 is connected with the first magnetic field component 411 and the second magnetic field component 421 to form an outer magnetic conduction path surrounding the fresh-keeping storage space.

The outside magnetic conduction passageway provides the closed passageway of magnetic force line for inside magnetic field to can gather the magnetic field, improve inside magnetic field's homogeneity, can reduce simultaneously that the magnetic field is released to the outside of magnetic field fresh-keeping storing container, reduce to outside other parts cause the interference (for example avoid magnetizing other parts etc.). The magnetic field connection member 431 is required to meet the requirement of aggregating external magnetic fields, and in general, the magnetic field connection member 431 is connected to the first magnetic field assembly 411 and the second magnetic field assembly 421 at a central position at the side thereof. The magnetic field connection 431 on each side may be one or more.

The magnetic field device 410 may be disposed outside the tub of the magnetic field fresh storage container or in an interlayer of the tub side wall. In some embodiments, the magnetic field device 410 may be disposed against the inner tub, for example, the first magnetic field assembly 411 and the second magnetic field assembly 421 may be disposed outside a set of opposing sidewalls of the inner tub, respectively, and configured to form a magnetic field within the fresh storage space. The magnetic field connection members 431 are disposed along other sidewalls of the inner tub, and the inner tub is provided with one or more fixing structures for each magnetic field connection member 431, and the magnetic field connection members 431 are fixed by the fixing structures, thereby ensuring reliable connection of the magnetic field connection members 431 with the first magnetic field assembly 411 and the second magnetic field assembly 421.

Fig. 3 is a schematic view showing a state in which the magnetic field preservation storing container 30 according to an embodiment of the present utility model is assembled, fig. 4 is a schematic view showing a tub 310 in the magnetic field preservation storing container 30 according to an embodiment of the present utility model, and fig. 5 is a schematic view showing a magnetic field device 410 in the magnetic field preservation storing container 30 according to an embodiment of the present utility model.

The barrel body 310 of the magnetic field preservation storage container 30 of the present embodiment is internally provided with a preservation storage space 330 for placing stored objects. The tub 310 may have a rectangular parallelepiped shape, and in some embodiments, the tub 310 may have a forward opening, and a drawer that may be drawn from the forward opening may be provided in the tub 310, so that the stored objects may be received by the drawer. The tub 310 may include a tub top wall 311, a tub bottom wall 312, a tub left side wall 314, a tub right side wall 315.

In some embodiments, tub 310 may include an inner tub 318. The tub 310 may further include a tub outer shell 3101 outside the inner tub 318, the outer shell 3101 being the outermost layer of the fresh storage container 30. In some embodiments, the tub outer shell 3101 may not be provided outside a portion of the side wall of the inner tub 318, but other insulation or injection molding or adjacent components within the refrigerator may be used as the outermost layer of the fresh storage container 30. In this embodiment, a case with a tub cover 3101 will be described.

The magnetic field device 410 in the magnetic field preservation storage container 30 may include: the first magnetic field assembly 411 and the second magnetic field assembly 421 are respectively disposed on a set of opposite sidewalls of the tub 310, and configured to form a magnetic field in the fresh storage space 330. The first magnetic field assembly 411 and the second magnetic field assembly 421 may be disposed at the tub top wall 311 and the tub bottom wall 312, or at the tub left side wall 314 and the tub right side wall 315, respectively. In embodiments where the magnetic field preservation storage container 30 employs a drawer-type configuration, the tub top wall 311 and the tub bottom wall 312 are spaced apart a smaller distance and have a larger area, and the first magnetic field assembly 411 and the second magnetic field assembly 421 are preferably disposed on the tub top wall 311 and the tub bottom wall 312. In some embodiments, the first magnetic field assembly 411 and the second magnetic field assembly 421 may be disposed within the middle interlayer 331 of the tub 310. In other embodiments, the first magnetic field assembly 411 and the second magnetic field assembly 421 may also be disposed outside the inner tub 318 of the tub 310.

Each of the magnetic field connection members 431 includes a body plate 4312 and flanges 4311 extending from both ends of the body plate 4312 toward the first magnetic field assembly 411 and the second magnetic field assembly 421, respectively. The main body plate 4312 of the magnetic field connection member 431 is respectively disposed in a sidewall of the tub 310 where the tub is connected to the sidewalls of the first magnetic field assembly and the second magnetic field assembly.

For example, in case that the first magnetic field assembly 411 and the second magnetic field assembly 421 may be disposed in the tub top wall 311 and the tub bottom wall 312, respectively, the body plate 4312 of the magnetic field connection 431 may be disposed at the tub left side wall 314, the tub right side wall 315, the tub rear wall, the tub front wall (in case that the tub 310 has a side wall at the front side); the flange 4311 is disposed at the top or bottom end of the body plate 4312. The number of the magnetic field connection members 431 may be two, and the body plates 4312 of the two magnetic field connection members 431 may be disposed on the left sidewall 314 and the right sidewall 315 of the tub to form an annular external magnetic circuit.

Also for example, in the case where the first magnetic field assembly 411 and the second magnetic field assembly 421 may be disposed on the tub left side wall 314 and the tub right side wall 315, respectively, the main body plate 4312 of the magnetic field connection 431 may be disposed on the tub top wall 311, the tub bottom wall 312, the tub rear wall, and the tub front wall (in the case where the tub 310 has a side wall on the front side); the flange 4311 is disposed at the left or right end of the body plate 4312. The number of the magnetic field connection members 431 may be two, and the body plates 4312 of the two magnetic field connection members 431 may be disposed on the left sidewall 314 and the right sidewall 315 of the tub to form an annular external magnetic circuit.

The magnetic field connection member 431 may be connected to the first and second magnetic conductive plates 413 and 423, respectively, through the flange 4311. The magnetic field connection member 431 extends the flange 4311 from both ends of the body plate 4312 toward the first magnetic field assembly 411 and the second magnetic field assembly 421, respectively, so as to be connected to the first magnetic conductive plate 413 and the second magnetic conductive plate 423 through the flange 4311, respectively.

The magnetic field connection member 431 is connected to the first magnetic field assembly 411 and the second magnetic field assembly 421 through the flange 4311, so that a more convenient assembly manner can be realized. In this connection, the magnetic field connection member 431 may be more reliably connected to the first magnetic field assembly 411 and the second magnetic field assembly 421, and the magnetic circuit communication is smoother.

In order to avoid affecting the distribution of the magnetic field, the end of the flange 4311 of the magnetic field connection element 431 is required to have a certain gap with the edges of the first magnetic source piece 414 and the second magnetic source piece 424.

One or more fixing structures are provided on the inner tub 318 for each magnetic field connection member 431, and the magnetic field connection members 431 are fixed to the tub 310 by using the fixing structures, so that the flanges 4311 of the magnetic field connection members 431 are ensured to be reliably connected with the first magnetic field assembly 411 and the second magnetic field assembly 421.

In the prior art, the magnetic field device is generally assembled and formed, and then is integrally assembled on the magnetic field fresh-keeping container, and when the magnetic field device needs to be fixed, a first magnetic field assembly 411 or a second magnetic field assembly 421 with a large clamping area, such as a claw, is generally used. However, as the inventor found during the development process, the magnetic field device 410 and the tub 310 are generally made of different materials, and the physical properties thereof are greatly different. In particular, when the magnetic field preservation storage container 30 is applied to a refrigerator, the magnetic field device 410 is easy to loose during long-term refrigeration and storage, and the magnetic field device 410 may be broken when serious, which results in greatly reduced preservation storage effect.

In addition, due to the distribution of the magnetic field and the structural requirement, the connection contact position between the flanges 4311 of the two magnetic field connectors 431 and the first magnetic field component 411 and the second magnetic field component 421 is smaller, and the connection part of the flanges is also likely to be disconnected due to stress in the alternative process of refrigeration and storage after long-term use.

As a result of the above intensive studies, the inventors have firmly fixed the magnetic field connection member 431 to the tub 310 by providing a fixing structure dedicated to fixing the magnetic field connection member 431 to the tub 310, thereby avoiding the above-mentioned problems, ensuring long-term operation stability of the magnetic field components in the magnetic field fresh-keeping storage container 30, and reducing external stress of the magnetic field connection member 431, thereby ensuring that the magnetic field connection member 431 can reliably connect the first magnetic field assembly 411 and the second magnetic field assembly 421.

The inner tub 318 may be formed by injection molding, internally for receiving drawers, or directly receiving stored objects. In some embodiments, the inner tub 318 may be formed as a single piece or by splicing multiple inner tub components via a clip connection or other connection, for example, the inner tub 318 may be split into three to four inner tub components according to the convenience requirement of assembly.

The first magnetic field assembly 411, the second magnetic field assembly 421, and the magnetic field connection 431 may be disposed between the tub outer shell 3101 and the inner tub 318, respectively. The first magnetic field component 411, the second magnetic field component 421 and the two magnetic field connecting pieces 431 are fixed on the inner barrel 318, so that the magnetic source component is closer to the stored object, and the application efficiency of the magnetic field is improved.

In the configuration shown in fig. 3-5, the first magnetic field assembly 411 is disposed above the top wall of the inner tub 318, and the second magnetic field assembly 421 is disposed below the bottom wall of the inner tub 318; the main body plate 4312 of the magnetic field connection member 431 is disposed outside the lateral side walls (left side wall and right side wall) of the inner tub 318, and the flange 4311 is disposed at the upper end and the lower end of the main body plate 4312 and extends toward the sides of the first magnetic field assembly 411 and the second magnetic field assembly 421. Alternatively, the magnetic field connection members 431 may be three or more, and the body plates 4312 thereof may be disposed at outer sides of the lateral side walls, the rear wall, etc. of the inner tub 318, respectively.

Fig. 6 is a schematic perspective view of an inner tub 318 of a magnetic field preservation container according to an embodiment of the present utility model. One way of fixing the structure may be: the inner barrel 318 extends out of the protruding wall 381 at the top and bottom of the sidewall of the main body plate 4312 of the magnetic field connection member 431; the fixing structure further includes a through hole 3183, and the through hole is disposed on the protruding wall 381 and is matched with the contour of the flange 4311, that is, the size and shape of the through hole 3183 are matched with those of the flange 4311. The flange 4311 extends through the aperture 3183 to the first magnetic field assembly 411 or the second magnetic field assembly 421. That is, the inner tub 318 fixes the position of the magnetic field connection member 431 through the penetration hole 3183 formed on the protruding wall 381.

Fig. 7 is a schematic view of an inner tub 318 in a magnetic field preservation container according to another embodiment of the present utility model, and fig. 8 is a schematic view of a magnetic field device 410 in a magnetic field preservation container according to another embodiment of the present utility model; fig. 9 is a schematic diagram illustrating the relative positions of the inner tub 318 and the magnetic field device 410 in the magnetic field preservation container 30 according to another embodiment of the present utility model. The main body plate 4312 of the magnetic field connection member 431 is provided with a main body plate fixing hole 4314, and the main body plate fixing hole 4314 may be located at the middle of the main body plate 4312. The fixing structure includes a main body plate fixing structure 3812, where the main body plate fixing structure 3812 is disposed on the inner tub body at a position corresponding to the main body plate fixing hole 4314, and is connected to the main body plate fixing hole 4314. In this fixing manner, the body plate fixing structure 3812 may reliably fix the magnetic field connection member 431 to the sidewall of the inner tub 318. The main body plate fixing structure 3812 may be a protruding column disposed on the inner barrel 318, or may be a connecting piece such as a screw or a rivet.

In the field of magnetic fields, those skilled in the art know that gaps and holes on the magnetic conduction path will affect the distribution of the magnetic field, so that the holes are generally avoided on the magnetic conduction path. Through a great deal of research and testing, the inventor determines the size of the fixing hole with small influence on the magnetic field distribution. That is, the ratio of the aperture of the body plate fixing hole 4314 to the width direction of the body plate 4312 is set to 20% or less, and the aperture of the body plate fixing hole 4314 may be set to 20mm or less, and further 10mm or less, for example, 10mm, 8mm, 6mm may be selected so as to be engaged with the fastener of the corresponding diameter. By this arrangement, on the one hand, the connection reliability of the main body plate 4312 can be ensured, and on the other hand, the influence on the magnetic field distribution can be reduced.

Each of the magnetic field connection members 431 may be disposed in a direction perpendicular to the first and second magnetic conductive plates 413 and 423. That is, the magnetic field connection 431 provides the shortest magnetic communication path connecting the first magnetic field assembly 411 and the second magnetic field assembly 421. In some embodiments, the magnetic field connection 431 may have a uniform width from the end connected to the first magnetic field assembly 411 to the end connected to the second magnetic field assembly 421, that is, the magnetic field connection 431 has a uniform width as a whole.

The tub enclosure is omitted from fig. 10-12 for ease of illustration of the securing structure.

In this fixing manner, a flange fixing hole 4313 is formed in the flange 4311, and the fixing structure further includes a flange fixing structure 3811, where the flange fixing structure 3811 is disposed on the top wall and the bottom wall of the inner tub 318 at a position corresponding to the flange fixing hole 4313, and is connected to the flange fixing hole 4313. The flange fixing structure 3811 can ensure structural reliability of the flange 4311 and the fixing positions of the first magnetic field assembly 411 and the second magnetic field assembly 421 by fixing the flange 4311. The flange fixing structure 3811 may fix the flange fixing hole 4313 using bolts, rivet bolts, or the like.

Both ends of the magnetic field connection member 431 are respectively connected to the first magnetic conductive plate 413 and the second magnetic conductive plate 423, and corresponding sides of the first magnetic field assembly 411 and the second magnetic field assembly 421 are corresponding sides of the first magnetic conductive plate 413 and the second magnetic conductive plate 423.

The magnetic source sheet may be attached to the side of the magnetic conductive plate near the inside of the fresh storage space 330, that is, the first magnetic source sheet 414 is located below the first magnetic conductive plate 413, and the second magnetic source sheet 424 is located above the second magnetic conductive plate 423. The flange 4311 of the magnetic field connection member 431 abuts against the edge of the side surface of the magnetic conductive plate near the inside of the fresh storage space 330 by using the side surface far from the inside of the fresh storage space 330. I.e., the top flange abuts against the edge of the lower surface of the first magnetic conductive plate 413; i.e., the top flange abuts against the edge of the upper surface of the second magnetic conductive plate 423.

Fig. 13 is a schematic perspective view of a magnetic field preservation storage container 30 in accordance with one embodiment of the present utility model. The magnetic field preservation storage container 30 is of a drawer type structure. The tub 310 is box-shaped as a whole and has a forward opening. The drawer 320 is drawably disposed inside the tub 310 through the forward opening. In a state that the drawer 320 is placed in the tub 310, the forward opening of the tub 310 may be sealed, so that a closed storage environment is formed inside the tub 310, and thus the drawer 320 and the tub 310 together define a fresh-keeping storage space 330. In a state that the drawer 320 is pulled out of the tub 310, the drawer 320 exposes a space at the top for taking and placing objects to be stored.

The rear part of the top wall 311 of the barrel body is close to the rear wall 313 of the barrel body, and a barrel body air supply opening 316 connected with a fresh-keeping container air supply channel is arranged, and the fresh-keeping container air supply channel can be an air channel for providing refrigerating air flow for the fresh-keeping storage container 30. The area of the tub top wall 311 where the tub air supply 316 is located may be set to have a certain inclination angle so as to be matched with the fresh container air supply passage. The tub air return 317 is disposed at one lateral side of the tub air supply 316 and spaced apart from the tub air supply 316.

Another requirement of the magnetic field preservation storage container 30 to achieve long-term preservation storage is to maintain the temperature in the preservation storage space 330 within a set preservation temperature range, and the refrigeration process will not be too low or too high, especially the temperature of each area of the preservation storage space 330 is uniform. In some embodiments, the fresh temperature range may be set at-2 ℃ to 1 ℃, for example, may be set at-2 ℃ to 0 ℃. The stored articles are not only prevented from being frozen, but also can maintain the optimal fresh-keeping temperature. The preservation temperature range can be set by a person skilled in the art according to the specific state of the stored object, and the specific numerical range is only illustrative. The refrigerating air flow directly contacts with the stored objects, which obviously causes the stored objects to be supercooled to be frozen or damaged by tissues, thereby affecting the fresh-keeping effect of the stored objects. In addition, the refrigerant air flow cannot uniformly flow through the whole storage space, which may lead to uneven temperature of the fresh storage space 330 and also to reduced fresh storage effect. The magnetic field preservation storage container 30 of the embodiment optimizes the internal air path structure, avoids the refrigerating air flow from entering the preservation storage space 330 and contacting with the stored objects, and can ensure the stable and uniform temperature inside the preservation storage space 330.

Fig. 14 is a schematic view of a refrigerator 10 according to one embodiment of the present utility model; fig. 15 is a schematic view of the refrigerator 10 shown in fig. 14 after the upper door 11 is hidden. The refrigerator of the present embodiment may generally include a cabinet 12, a door 11, and a refrigerating system (not shown in the drawings). The housing 12 may define at least one open-front storage compartment, and typically a plurality of compartments, such as a refrigerated storage compartment 121, a frozen storage compartment, a variable temperature storage compartment, and the like. The number and function of particular storage compartments may be configured according to the needs in advance. The cross-type side-by-side refrigerators shown in fig. 14 and 15 are only examples, and those skilled in the art can configure the number, functions and layout of the specific storage compartments according to the need.

The refrigerator 10 of the present embodiment may be an air-cooled refrigerator. An air path system is arranged in the box body, and a fan is used for sending the refrigerating air flow subjected to heat exchange by a heat exchanger (an evaporator, not shown in the figure) to the storage compartment through an air supply opening and then returning to the air duct through an air return opening. And refrigeration is realized. The plurality of storage compartments can be spatially divided in a rack, a shelf, a drawer and the like, so that corresponding storage functions, such as freezing, drying storage and the like, are realized.

One or more magnetic field preservation storage containers 30 may be disposed within the refrigerator 10 of the present embodiment. In some alternative embodiments, the magnetic field preservation storage container 30 may be disposed in one or more of the storage compartments, and long-term high-quality cold fresh preservation of food materials such as meat, fish, etc. is achieved through magnetic field and temperature regulation. For example, the magnetic field preservation storage container 30 may be disposed in the refrigeration storage compartment 121, and other drawer-type storage containers 122 may be disposed in the refrigeration storage compartment 121 besides the magnetic field preservation storage container 30, for example, fig. 15 shows an example in which, in addition to the magnetic field preservation storage container 30, the refrigeration storage compartment 121 is further provided with other three drawer-type storage containers 122, where one drawer-type storage container 122 is disposed laterally in parallel with the magnetic field preservation storage container 30.

The refrigerator 10 of the present embodiment achieves the effect of preserving and storing by combining the effect of the magnetic field with the accurate temperature control of the magnetic field preserving storage container 30. In order to realize accurate temperature control, the air path system of the refrigerator of the embodiment can provide a special fresh-keeping container air supply channel for the magnetic field fresh-keeping storage container 30, and realize control of on-off and/or size of refrigerating air flow of the magnetic field fresh-keeping storage container 30. Through the actual test of the test sample, the preservation storage container 30 and the refrigerator applying the embodiment can greatly prolong the preservation storage time of the stored objects, for example, for fresh meat fish, the preservation time can be prolonged to 5 to 7 days, and the use experience is greatly improved.
