The prior studies found that the magnetic field had a greater effect on the formation of ice crystals during the freezing process. When the magnetic field is used for freezing food materials, the magnetic field limits the free path of water molecules to a certain extent, and the free path is represented by hydrogen bond breakage in water molecular clusters. In the phase change process, crystal nucleus growth is inhibited, the growth rate of the crystal crystals is higher than the migration rate of water molecules, and the generated crystal crystals are smaller, so that the damage to cells is also small, the juice loss rate is reduced, and the nutrition and the taste of food materials are better preserved.

When the magnetic field is used for refrigerating food materials, the supercooling degree of the food materials can be reduced, for example, the freezing temperature of beef is minus 2 ℃, and when the magnetic field acts on the beef, the freezing temperature of the beef can be reduced to minus 5 ℃, so that the beef can be refrigerated at a lower temperature and kept fresh.

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 include a shell, a liner, insulation, trim, and the like.

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 123, a variable temperature storage compartment 122, and the like. One skilled in the art can configure the number, function, and layout of the specific storage compartments as desired. The number of the door bodies 11 can be matched with the number of the storage compartments, so that the storage compartments can be opened independently one by one. The door body 11 may also take the form of a side-hung door, a side-sliding door, a sliding door, or the like. The number and function of particular storage compartments may be configured according to the needs in advance. According to the different layout modes of the storage compartments, the refrigerator can be set as a single-door refrigerator or a multi-door refrigerator, and the multi-door refrigerator can further comprise: double door refrigerators, triple door refrigerators, side-by-side refrigerators, french refrigerators, italian refrigerators, and the like. The french four-door refrigerator shown in figures 1 and 2 is only an example,

in some embodiments, the preservation temperature of the refrigerated storage compartment 121 may be 0-9 ℃, or may be 2-7 ℃, for example; the preservation temperature of the freezing storage compartment 123 can be-22 to-14 ℃, or can be-20 to 16 ℃, and the variable temperature storage compartment 122 is arranged between the refrigerating storage compartment 121 and the freezing storage compartment 123. The temperature change storage compartment 122 can be adjusted as desired to store the appropriate food or as a fresh storage compartment.

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. For example, the fresh storage vessel 30 can be disposed within any of the refrigerated storage compartment 121, the frozen storage compartment 123, and the variable temperature storage compartment 122. For another example, the fresh-keeping storage containers 30 may be simultaneously disposed in a plurality of the refrigerating storage compartments 121, the freezing storage compartments 123, and the temperature-changing storage compartments 122, that is, the fresh-keeping storage containers 30 may be simultaneously disposed in a plurality of different storage compartments. For another example, a plurality of fresh storage containers 30 may be provided simultaneously in one storage compartment as required. Fig. 2 shows an example of a fresh food storage receptacle 30 disposed within a refrigerated storage compartment 121. The fresh storage vessel 30 may be a drawer-structured storage vessel. Other drawer storage containers may be provided in the refrigerated storage compartment 121 in addition to the fresh storage container 30.

The refrigerator 10 of the present embodiment may be an air-cooled refrigerator. Fig. 3 is a schematic view of a cooling air path system of the refrigerator 10 according to an embodiment of the present utility model. An air path system is provided in the case 12, and sends air passing through the heat exchanger (evaporator) to each storage compartment. The air duct system is typically disposed on the back of the housing 12 and is constructed using duct covers, foam pieces, and the like. The number of evaporators in a refrigeration system is divided into a plurality of systems and a single system. Wherein the multi-system comprises a plurality of evaporators, each evaporator being responsible for the refrigeration of a portion of the storage compartment. Taking the cooling air path system shown in fig. 3 as an example, a cooling air duct 131 is formed at the back of the cooling storage compartment 121. A refrigeration evaporator 133 is disposed within the refrigeration tunnel 131, and a refrigeration blower 132 causes a refrigeration airflow to form the refrigerated storage compartment 121. A refrigerating air duct 135 is formed at the back of the refrigerating compartment 123 and the temperature-varying compartment 122. A freezing evaporator 137 is disposed within the freezing and refrigerating air duct 135, and the freezing and refrigerating fan 136 causes a freezing air flow to be formed in the freezing compartment 123 and/or the temperature-changing compartment 122.

The refrigeration evaporator 133 and the refrigeration evaporator 137 may be separately controlled on and off, for example, the refrigeration evaporator 137 and the refrigeration chiller 136 may be turned on to cool when the temperature of the refrigeration compartment 123 reaches a refrigeration on condition. The freezing air flow is sent from the position of the freezing evaporator 137 to the freezing compartment 123 through the air supply openings at the respective positions of the freezing compartment 123. After the refrigerating air flow is sent into the refrigerating compartment 123, heat exchange is performed with the stored object, and the temperature is lowered. The air flow cycle is then completed by returning the chilled evaporator 137 to the location through the return air inlet of the chilled storage compartment 123.

Also for example, the refrigeration evaporator 133 and the refrigeration chiller 132 may initiate refrigeration when the temperature of the refrigerated storage compartment 121 reaches a refrigeration initiation condition.

The refrigerating air flow is sent from the position of the refrigerating evaporator 133 to the refrigerating compartment 121 through the air door at different positions of the refrigerating compartment 121, and then flows forward from the inside of the refrigerating compartment 121, exchanges heat with the stored object in the refrigerating compartment 121, and cools the stored object. The refrigerated air flow then returns from the refrigerated storage compartment 121 via the return air inlet to the location of the refrigerated evaporator 133, completing the air flow cycle. A plurality of dampers may be provided in the refrigeration duct 131, and may adjust the direction of the refrigeration airflow. The plurality of air doors may include a fresh-keeping refrigeration air door 134, where the fresh-keeping refrigeration air door 134 is dedicated to adjusting the on/off and the size of the refrigeration air flow of the fresh-keeping storage container 30. Alternatively, in some embodiments, a concentrated air flow distribution device may be disposed within the refrigeration air duct 131, where the concentrated air flow distribution device communicates with the air duct leading to different areas of the refrigerated storage compartment 121, and may distribute the flow of refrigeration air to different areas of the refrigerated storage compartment 121. Wherein the fresh storage vessel 30 may be provided with a dedicated refrigeration airflow path for independent refrigeration control.

The refrigeration start-stop conditions of the refrigeration evaporator 133 and the refrigeration evaporator 137 are well known to those skilled in the art, and can be set by those skilled in the refrigerator art according to the refrigeration requirement. The refrigerator of the present embodiment is particularly improved with respect to the way in which the fresh storage vessel 30 is cooled.

The fresh-keeping storage container 30 is disposed in a fresh-keeping storage compartment (which may be a part of the fresh-keeping storage compartment 121 or independent of the fresh-keeping storage compartment 121), and an air supply port 316 and an air return port 317 for communicating with the refrigeration air duct 131 are formed in a back plate at the rear part of the fresh-keeping storage container 30, so that cold air in the refrigeration air duct 131 is introduced into the air supply port 316, and is returned to the refrigeration air duct from the air return port 317 after heat exchange with the fresh-keeping storage container 30.

An insulating layer 124 is provided between the fresh-keeping compartment in which the fresh-keeping storage container 30 is located and the space of the adjacent fresh-keeping compartment 121. The insulating layer 124 may set the fresh storage temperature of the fresh storage compartment to be different from the storage temperature of the surrounding storage space. The fresh-keeping storage temperature can be set to be lower than the cold-keeping storage temperature, the characteristic that supercooling is not easy to freeze is utilized in a magnetic field environment, longer-time fresh-keeping storage is realized, and for example, the fresh-keeping storage temperature can be set to be-2 ℃ to 0 ℃.

In the case where the fresh air cooling damper 134 is opened or the concentrated air flow distribution device is opened to supply air to the fresh storage compartment in which the fresh storage container 30 is located, the cooling air flow is supplied from the air supply port to the fresh storage container 30. In this embodiment, the cooling air flow does not directly enter the fresh-keeping storage space 330, but exchanges heat around the fresh-keeping storage container 30, so as to avoid the cooling air flow with lower temperature from directly contacting the stored objects in the fresh-keeping storage space 330. One way of the flow of refrigerant gas around the fresh storage vessel 30 is: the air flow enters the top of the fresh food storage vessel 30 from the air supply opening 316, then flows from the back to the front along the top of the fresh food storage vessel 30, then flows from the front of the fresh food storage vessel 30 from the top to the bottom, and finally flows from the front to the back along the bottom of the fresh food storage vessel 30 back to the air return opening 317. The cooling air path of the fresh-keeping storage container 30 surrounds the whole fresh-keeping storage container 30 for a 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.

A heat exchange air duct 340 is formed around the fresh storage compartment 30, the heat exchange air duct 340 extending from the supply air opening 316 forwardly along a side wall (e.g., top wall) of the fresh storage compartment 30 to the front of the fresh storage compartment 30 and then rearwardly along another side wall (e.g., bottom wall) to the return air opening 317.

In alternative embodiments, the heat exchange tunnel 340 may be wrapped around the fresh food container 30 in other ways, such as from the left side forward, from the front of the drawer laterally to the right, and then back from the right side to the back side, i.e., laterally. That is, the heat exchanging air duct 340 extends from the air supply opening 316 forward along the left side wall (or right side wall) of the fresh food storage receptacle 30 to the front of the fresh food storage receptacle 30 and then extends rearward along the right side wall (or left side wall) to the return air opening 317.

In order to improve the refrigerating efficiency, the refrigerating air flow is generally required to be sent into the storage space, and even if the direct current blowing is used for avoiding local supercooling, the adopted technical means is generally to use the hole with smaller hole diameter to blow air into the drawer storage space or to set a special air guide channel in the storage space. The fresh-keeping storage container 30 of the embodiment creatively provides a scheme that the refrigeration air flow is not sent into the fresh-keeping storage space 330 and indirect refrigeration is realized by using the surrounding air path, the fresh-keeping effect is better improved by combining the magnetic field, and the technical prejudice of the technicians in the field is overcome.

Fig. 4 is a schematic view of a cooling air path system of a refrigerator 10 according to another embodiment of the present utility model. In this embodiment, refrigeration of the refrigerated storage compartment 121, the variable temperature storage compartment 122, and the refrigerated storage compartment 123 is achieved using the refrigeration evaporator 137. A refrigerating air duct 131 is formed at the back of the refrigerating compartment 121. A refrigerating air duct 135 is formed at the back of the refrigerating compartment 123 and the temperature-varying compartment 122. A refrigeration evaporator 137 is disposed in the refrigeration air duct 135, and the refrigeration fan 136 promotes the formation of a refrigeration air flow.

A refrigeration damper 138 may be disposed between the refrigeration air duct 135 and the refrigeration air duct 131. When the refrigeration compartment 121 needs to be refrigerated separately, the refrigeration damper 138 is opened, and the dampers at the air supply ports of the refrigeration compartment 123 and the temperature-variable compartment 122 may be all closed, so that the refrigeration fan 136 causes the formed refrigeration air flow to be sent into the refrigeration air duct 131 through the refrigeration damper 138. When the freezing storage compartment 123 or the temperature-changing storage compartment 122 needs to be cooled separately, the refrigeration air door 138 is closed, and the air doors at the air supply openings of the freezing storage compartment 123 and the temperature-changing storage compartment 122 are opened correspondingly, so that the refrigerating air flow formed by the refrigerating fan 136 can be sent into the freezing storage compartment 123 and the temperature-changing storage compartment 122. When the refrigeration compartment 121 and the refrigeration compartment 123 need to be refrigerated simultaneously, the refrigeration damper 138 and the damper at the air supply port of the refrigeration compartment 123 may be both opened, and the refrigeration air flows in the refrigeration air duct 135 and the refrigeration air duct 131 simultaneously. The refrigeration system of the refrigerator 10 can adjust the frequency of the compressor to adjust the refrigeration capacity of the evaporator to match the refrigeration requirements of the different storage compartments.

The back plate of the rear part of the preservation storage container 30 is also provided with an air supply port 316 and an air return port 317 for communicating the refrigeration air duct 131, so that the air supply port 316 introduces cold air in the refrigeration air duct 131, exchanges heat with the preservation storage container 30 and returns to the refrigeration air duct from the air return port 317.

An insulating layer 124 is provided between the fresh-keeping compartment in which the fresh-keeping storage container 30 is located and the space of the adjacent fresh-keeping compartment 121. The insulating layer 124 may set the fresh storage temperature of the fresh storage compartment to be different from the storage temperature of the surrounding storage space. The fresh-keeping storage temperature can be set to be lower than the cold-keeping storage temperature, the characteristic that supercooling is not easy to freeze is utilized in a magnetic field environment, longer-time fresh-keeping storage is realized, and for example, the fresh-keeping storage temperature can be set to be-2 ℃ to 0 ℃.

In the case where the fresh air cooling damper 134 is opened or the concentrated air flow distribution device is opened to supply air to the fresh storage compartment in which the fresh storage container 30 is located, the cooling air flow is supplied from the air supply port to the fresh storage container 30. In this embodiment, the cooling air flow does not directly enter the fresh-keeping storage space 330, but exchanges heat around the fresh-keeping storage container 30, so as to avoid the cooling air flow with lower temperature from directly contacting the stored objects in the fresh-keeping storage space 330.

A heat exchange air duct 340 is formed around the fresh storage compartment 30, the heat exchange air duct 340 extending from the supply air opening 316 forwardly along a side wall (e.g., top wall) of the fresh storage compartment 30 to the front of the fresh storage compartment 30 and then rearwardly along another side wall (e.g., bottom wall) to the return air opening 317.

Fig. 5 is a schematic view of a fresh storage vessel 30 for a refrigerator according to one embodiment of the present utility model. Fig. 6 is an exploded view of the components of the fresh storage vessel 30 shown in fig. 5.

The fresh-keeping storage vessel 30 for a refrigerator of the present embodiment may generally include: a storage body 320, a container housing 310, one or more magnetic assemblies 410. The storage main body 320 is provided therein with a fresh storage space 330 for storing stored objects. The container housing 310 is disposed at an outer side of the storage main body 320 to define a space accommodating the storage main body 320. The container frame 310 can be used as a shell of the storage main body 320, and when the fresh-keeping storage container 30 is refrigerated, the container frame 310 is refrigerated by the refrigerating air flow, and the container frame 310 uniformly releases the cold into the fresh-keeping storage space 330, so that local supercooling can be avoided. In order to prevent the temperature of the partial area from being too low due to too fast cooling, an insulation layer, an air interlayer and the like can be further arranged on the inner side of the container outer frame 310, so that the refrigerating process meets the requirements of fresh-keeping and storage.

Another important aspect of achieving fresh storage is the requirement to generate a satisfactory magnetic field within fresh storage space 330. Through intensive research on the preservation effect, the magnetic field parameters required by the preservation storage container 30 of the present embodiment for achieving long-term preservation storage are preferentially configured as the effective magnetic field intensity 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.

In this embodiment, the arrangement position of the magnetic component 410 in the fresh storage container 30 is optimized, and the magnetic component 410 is directly arranged in the fresh storage space 330 and is closer to the stored object, so that the magnetic field beneficial to the fresh storage can be formed in the fresh storage space 330 by using smaller size and fewer magnetic components 410.

The storage body 320 may generally include: a container bottom plate 321 and a peripheral side plate 322. The container bottom 321 may have a rectangular shape, and a top surface thereof is used to support the stored objects. The peripheral side panels 322 extend upwardly from the edges of the base panel 321 and cooperate with the container base panel 321 to define a fresh storage space 330 for storing items to be stored. The peripheral side panel 322 may include lateral side panels (left side panel, right side panel), front side panel, rear side panel. The peripheral side panels 322 together define a peripheral boundary of the fresh storage space 330. The entire reservoir body 320 may be formed in a rectangular box shape, and in some alternative embodiments, the reservoir body 320 may also include a top plate (e.g., drawer cover plate).

One or more magnetic assemblies 410 and two first magnetically permeable connectors 311, 312 are also provided on the reservoir body 320.
