Fig. 4 is a schematic diagram illustrating the relative positions of the tub 310 and the magnetic field device in the fresh storage vessel 30 according to an embodiment of the present utility model.

The fresh storage vessel 30 may include: a tub 310. The tub 310 is generally rectangular and may include a tub top wall 311, a tub bottom wall 312, a tub rear wall 313, a tub left side wall 314, and a tub right side wall 315. In some embodiments, the fresh storage vessel 30 can be a drawer-type structure and further include a drawer 320. The tub 310 has a forward opening through which the drawer 320 is drawably disposed inside the tub 310. The drawer 320 is provided at a front side thereof with a drawer end plate assembly 321. In a state that the drawer 320 is placed in the tub 310, the drawer end plate assembly 321 may seal the forward opening of the tub 310 such that a closed storage environment is formed inside the tub 310, and thus the drawer 320 and the tub 310 together define the 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 tub 310 may further include a tub outer shell 319 outside the inner tub 318, the outer shell 319 being the outermost layer of the fresh storage vessel 30. In some embodiments, the tub housing 319 may not be provided outside of a portion of the side wall of the inner tub 318, and other insulation or injection molding or adjacent components within the refrigerator may be used as the outermost layer of the fresh food storage vessel 30.

The inner tub 318 has a fresh storage space 330 therein for storing stored objects. In the case of a drawer type structure, the inner tub 318 may define a fresh storage space 330 together with the drawer 320. The inner tub 318 may be formed by splicing a plurality of inner container parts by a clamping connection or other connection methods, for example, the inner container parts may be split into three to four inner container parts according to the convenience requirement of assembly. The inner tub 318 serves as a tub inner layer in which the drawer 320 is disposed.

A part of the sidewall of the tub 310 has a sandwich space 331 therebetween. The interlayer space 331 is used to dispose a magnetic field device, an internal air passage, a heat insulating layer, or the like, or a part of the above. For example, the tub top wall 311, the tub bottom wall 312, the tub rear wall 313, the tub left side wall 314, and the tub right side wall 315 may respectively form the interlayer space 331.

The first magnetic field assembly 411 may be disposed on an outer side of a sidewall of the inner tub 318, and one or more fixing structures are disposed on the inner tub, and the first magnetic field assembly is fixed by the fixing structures. The side walls of the inner tub 318 may be a top wall, a bottom wall, a left side wall, a right side wall, a rear wall, etc. For example, the first magnetic field assembly 411 may be disposed on the tub top wall 311 or the tub bottom wall 312, i.e., on the top or bottom of the inner tub 318; for another example, the first magnetic field assembly 411 may be disposed on the left sidewall 314 or the right sidewall 315 of the tub, i.e., on the left or right side of the inner tub 318. A person skilled in the art can set the first magnetic field assembly 411 to any one of the tub top wall 311, the tub bottom wall 312, the tub left side wall 314, and the tub right side wall 315 according to the structural characteristics of the fresh storage container 30.

In the embodiment of the fresh storage vessel 30 using a drawer structure, the spacing between the top wall 311 and the bottom wall 312 is smaller and the area is larger, and the first magnetic field assembly 411 is preferably disposed on the top wall 311 or the bottom wall 312, i.e. on the top or the bottom of the inner tub 318.

The first magnetic field assembly 411 is abutted against the inner tub 318. One or more fixing structures are provided on the inner tub 318, and the first magnetic field assembly 411 is fixed using the fixing structures.

The following describes the fixing structure by taking the example that the first magnetic field assembly 411 is disposed above the top wall of the inner tub 318, and those skilled in the art can implement the scheme that the first magnetic field assembly 411 is disposed on other side walls of the inner tub 318 on this basis.

Fig. 5 is a schematic view of an inner tub 318 of a fresh storage vessel 30 according to one embodiment of the utility model. Fig. 6 is a schematic view of the inner tub 318 of the fresh storage vessel 30 holding the side wall of the first magnetic field assembly 411 according to one embodiment of the present utility model.

The fixing structure may include: accommodating support structure 3181. The receiving support structure 3181 is provided on a side of the inner tub 318 opposite to the first magnetic field assembly 411, and has a recess adapted to the outer shape of the first magnetic field assembly 411 such that the first magnetic field assembly 411 is partially embedded in the recess. The accommodating support structure 3181 accommodates the first magnetic field assembly 411 by using the concave portion, and the shape of the concave portion is matched with the shape of the first magnetic field assembly 411, so that the position of the periphery of the first magnetic field assembly 411 can be limited. In an embodiment in which the inner barrel 318 is made of plastic, the receiving support structure 3181 may be injection molded to mate with the first magnetic field assembly 411. The accommodating support structure 3181 surrounds the first magnetic field assembly 411, the accommodating support structure 3181 can have a support structure, and plastic parts are integrally formed in the injection molding machine during injection molding.

The fixation structure may also include a magnetically attractable fixation structure 3182. The magnetic attraction fixing structure 3182 is disposed on a side of the inner tub 318 opposite to the first magnetic field assembly 411, and configured to generate a magnetic attraction force on the first magnetic field assembly 411, and fix the first magnetic field assembly 411 using the magnetic attraction force. The magnetic attraction fixing structure 3182 may be provided with a permanent magnet or a ferromagnetic material having opposite poles to the first magnetic field assembly 411. The magnetic attraction fixing structure 3182 and the first magnetic field assembly 411 are fixed through magnetic attraction. In some embodiments, to avoid affecting the magnetic field distribution within the storage space 330, the magnetic attraction fixing structure 3182 may be disposed at a position opposite the first magnetic field assembly 411 near the edge. The magnetic fixing structure 3182 may be formed by integrally injection molding a metal material or other magnetically conductive material embedded in a plastic part. The first magnetic field component 411 is attracted and fixed with the metal or magnetic conductive material part of the plastic part during assembly.

The fixed structure may also include a plurality of jaws 3183. The plurality of jaws 3183 may be disposed at an outer circumference of a contact area of the inner tub 318 with the first magnetic field assembly 411, and configured to be engaged with an edge of the first magnetic field assembly 411. The plurality of jaws 3183 are secured by clamping the edges of the first magnetic field assembly 411.

The first magnetic field assembly 411 may be provided with a plurality of connection holes, and the fixing structure further includes a plurality of fastening holes 3184, the plurality of fastening holes 3184 being in one-to-one correspondence with the plurality of connection holes, and configured to penetrate the fastening holes 3184 and the corresponding connection holes by fasteners (e.g., screws, bolts, rivets, etc.), thereby fixing the first magnetic field assembly 411.

The accommodating support structure 3181, the magnetic fixing structure 3182, the claw 3183 and the fastening hole 3184 may be selected according to the requirement, and a person skilled in the art may select one fixing mode or multiple fixing modes according to the fixing requirement for cooperation. For example, when the accommodating support structure 3181, the magnetic fixing structure 3182 and the fastening holes 3184 are used to be matched, the first magnetic field assembly 411 is first installed in the accommodating support structure 3181, then matched with the magnetic fixing structure 3182 by magnetic attraction, so that the fastening holes 3184 are aligned with the connecting holes, and finally the fasteners are installed.

Fig. 7 is a schematic view of a side wall of an inner tub 318 of a fresh storage vessel 30 holding a first magnetic field assembly 411 according to another embodiment of the present utility model. The securing structure may also include glue injection grooves 3185. The glue injection groove 3185 is disposed on a side surface of the inner barrel 318 opposite to the first magnetic field assembly 411, and is configured to inject glue solution to adhere the first magnetic field assembly 411 by using the glue solution. The glue solution can be glass glue, AB glue, hot melt glue, etc. Alternatively, other fixing adhesives may be used to bond the inner tub 318 and the first magnetic field assembly 411.

Fig. 8 is a schematic view of a side wall of an inner tub 318 of a fresh storage vessel 30 holding a first magnetic field assembly 411 according to another embodiment of the present utility model. The fixation structure may also include a resilient fixation 3186. The elastic fixing member 3186 is disposed at an outer circumference of a side of the inner tub 318 opposite to the first magnetic field assembly 411, and is configured to be deformed by being pressed when the first magnetic field assembly 411 is mounted to the inner tub 318, thereby pressing the first magnetic field assembly 411 by a pressure generated by the deformation. The elastic fixing member 3186 may be supported by a deformable material such as a rubber member (rubber band), a spring piece, or the like. When the elastic fixing member 3186 is mounted, the elastic fixing member 3186 is deformed to form a gap with the inner tub 318, the first magnetic field assembly 411 is inserted into the gap, and then the force is stopped, the elastic fixing member 3186 is rebounded, and the first magnetic field assembly 411 is fixed by the force generated by the elastic deformation.

Fig. 9 is a schematic view of a pressure cap 3187 in a fresh storage vessel 30 according to another embodiment of the present utility model. The fixing structure may further include a pressing cover 3187, where the pressing cover 3187 covers a side of the first magnetic field assembly 411 away from the inner tub 318, and presses the first magnetic field assembly 411 onto the inner tub 318. The gland 3187 may be fastened to the inner tub 318 by fastening, welding, bonding, etc., so as to fix the space of the first magnetic field assembly 411 with the inner tub 318 by a limited place. The gland 3187 may be plastic, foam, or other insulating material. After the first magnetic field assembly 411 is positioned on the inner barrel 318, the gland 3187 and the inner barrel 318 are mounted above the first magnetic field assembly 411 in a clamping, welding, screw connection and other manners, so as to fix the first magnetic field assembly 411.

In addition to the above-described fixing structure, the fixing may be achieved by improving the structure of the first magnetic field assembly 411 itself and the installation process. For example, the first magnetic field assembly 411 is designed to be multi-layered, and the lamination of the multi-layered structure generates a great friction force so that the multi-layered structure cannot generate relative motion, thereby realizing fixation. For example, after the first magnetic field assembly 411 is positioned, a vacuum pump is used to pump out the gas between the first magnetic field assembly 411 and the inner barrel 318, and the fixation is achieved by a vacuum lamination mode.

Fig. 10 is a schematic diagram of a magnetic field device 410 in a magnetic field preservation container 30 according to an embodiment of the present utility model. Fig. 11 is an exploded view of the components of the magnetic field device 410 shown in fig. 10. Fig. 12 is a schematic diagram illustrating the cooperation of the first magnetic conductive plate 413 and the first magnetic source sheet 414 in the fresh storage container 30 according to an embodiment of the present utility model. The magnetic field device 410 may include a first magnetic field assembly 411 and a second magnetic field assembly 421 disposed opposite each other, and in some embodiments a magnetic field connection 431 may be further disposed to connect the first magnetic field assembly 411 and the second magnetic field assembly 421.

The first magnetic field assembly 411 and the second magnetic field assembly 421 are disposed opposite each other, and may be disposed in opposite sides of the tub 310 of the fresh storage vessel 30, such as in the tub top wall 311 and the tub bottom wall 312, or in the tub left side wall 314 and the tub right side wall 315, respectively. In embodiments where the fresh storage vessel 30 is configured using 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. For example, the first magnetic field assembly 411 is disposed outside the top wall of the inner tub 318, and the second magnetic field assembly 421 is disposed outside the bottom wall of the inner tub 318.

The first magnetic field assembly 411 and the second magnetic field assembly 421 may be substantially the same configuration, 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, a second magnetically permeable plate 423. The second magnetic field assembly 421 may be fixed to the inner tub 318 in the same manner as the first magnetic field assembly 411.

The side of the first magnetic conductive plate 413 facing the inner tub 318 has a planar area; the first magnetic source piece 414 is closely attached to the planar area; and the first magnetic conductive plate 413 extends outward around the planar area to form an extension 4131; at least a portion of the extension 4131 protrudes from the planar region toward the first magnetic source sheet 414 side, such that at least a portion of the extension 4131 forms a step with the planar region; the outer periphery of the first magnetic source piece 414 has a set distance D from the step.

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-described requirements of forming a magnetic field having an effective magnetic field strength in the range of 10-100GS (1-10 mT) and an effective magnetic field spacing in the range of 60-240mm in the fresh storage space 330. Through intensive research on the preservation effect, the magnetic field parameters of the preservation storage container 30 of the present embodiment are preferentially configured as the effective magnetic field strength range: 10-100GS (1-10 mT), further can be set to 20-80GS, still further can be set to 40GS-60GS, e.g. 10GS, 20GS, 40GS, 60GS, 80GS, 100GS, etc., effective spacing range of magnetic fields: 60-240mm, effective spacing range of magnetic field: 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 sheet 414 and the second magnetic source sheet 424 are set to be perpendicular to the own surfaces, respectively. The magnetic field directions of the first magnetic source sheet 414 and the second magnetic source sheet 424 may be set to be the same, that is, the opposite magnetic poles of the first magnetic source sheet 414 and the second magnetic source sheet 424 are opposite magnetic poles, so that the uniformity of the magnetic field may be further ensured.

The magnetic field connection member 431 connects the first magnetic field assembly 411 and the second magnetic field assembly 421 from both sides. The magnetic field connection member 431 may be made of the same material as the first and second magnetic conductive plates 413 and 423. In the embodiment where the first magnetic field assembly 411 and the second magnetic field assembly 421 are disposed on the top surface and the bottom surface of the fresh storage container 30, the magnetic field connection members 431 may be disposed on the left side surface and the right side surface of the fresh storage container 30, respectively, the top thereof is connected with the first magnetic field assembly 411, and the bottom thereof is connected with the second magnetic field assembly 421. The first magnetic field assembly 411, the second magnetic field assembly 421 and the magnetic field connection members 431 on both sides form an outer magnetic conduction path around the fresh-keeping storage container 30, and the fresh-keeping storage space 330 between the first magnetic field assembly 411 and the second magnetic field assembly 421 forms an internal magnetic field. The outside magnetic conduction path provides a closed path of magnetic force lines for the internal magnetic field, so that the magnetic field can be gathered, the uniformity of the internal magnetic field is improved, the release of the magnetic field to the outside of the fresh-keeping storage container 30 can be reduced, and the interference to other external parts (such as avoiding magnetization of other parts) is reduced.

One requirement of the fresh storage vessel 30 to achieve long-term fresh storage is to maintain the temperature within the fresh storage space 330 within a set fresh temperature range. To achieve the above refrigeration requirement, a refrigeration air path may be further disposed in the fresh storage container 30 and around the inner tub 318. For example, the air flow enters the tub 310 from the tub air supply 316, and is sent out from the tub air return 317 after the refrigeration cycle. The internal air path of the fresh-keeping storage container 30 surrounds the whole fresh-keeping storage container 30 for one circle, and can realize sufficient heat exchange to uniformly cool the fresh-keeping storage container 30 under the condition that the fresh-keeping storage space 330 is not accessed and can not directly contact stored objects.

Besides refrigerating the fresh-keeping storage space 330, the refrigerating air flow can also take away heat generated when the magnetic field device 410 generates a magnetic field, so that the temperature distribution in the fresh-keeping storage space 330 is not affected.

The present embodiment also provides a refrigerator 10 having the fresh-keeping storage vessel 30 of the above embodiment. Fig. 13 is a schematic view of a refrigerator 10 according to one embodiment of the present utility model; fig. 14 is a schematic view of the refrigerator 10 shown in fig. 13 with the upper door 11 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 refrigerator shown in fig. 13 and 14 is only an example, and those skilled in the art can configure the number, functions and layout of the specific storage compartments according to the requirements.

The refrigerator 10 of the present embodiment may be an air-cooled refrigerator, in which a fan is used to send a flow of cooling air, which is heat-exchanged by a heat exchanger (evaporator, not shown), to the fresh-keeping storage container 30. Since the refrigerator body, the door body and the refrigerating system of the refrigerator are all well known and easy to realize by those skilled in the art, the refrigerator body, the door body and the refrigerating system are not described in detail in order to not mask and obscure the improvement points of the application.

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 fresh food storage containers 30 may be disposed within the refrigerator 10 of this embodiment. In some alternative embodiments, the fresh-keeping 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.
