As shown in fig. 1 to 6, in one embodiment, the fresh storage vessel includes a tub 100 and a drawer 200. The tub 100 defines a receiving compartment 101, and an air supply duct 10 is defined in a top wall of the tub 100. Specifically, a top sidewall of the tub 100 is formed with an interlayer space 102, and the supply air duct 10 is formed in the interlayer space 102.

The drawer 200 is drawably provided in the accommodating compartment 101, and the drawer 200 is formed with a storage space 201. The front end plate 210 of the drawer 200 is formed with an over-air duct 20. A cooling air duct 30 is formed between the bottom sidewall of the drawer 200 and the bottom sidewall of the tub 100 in the closed position. The rear end of the tub 100 is formed with an air inlet 103 to guide the air flow entering from the air inlet 103 to the air passing duct 20 via the air passing duct 10, and guide the air flow from the air passing duct 10 to the cool air transferring duct 30 via the air passing duct 20. The rear end of the tub 100 is further provided with an air return port 104, and cool air finally flows out of the container through the air return port 104.

Referring to fig. 5, in particular, the tub 100 has a box shape as a whole and has a forward opening (i.e., an opening of the accommodating compartment 101). That is, the tub 100 has five sidewalls, i.e., a tub top sidewall, a tub bottom sidewall, a tub rear sidewall, a tub left sidewall, and a tub right sidewall, which together enclose a receiving compartment 101 having an opening.

As shown in fig. 1 to 6, the drawer 200 is drawably provided inside the tub 100 through the opening of the accommodating compartment 101. Drawer 200 includes a bottom panel, a rear panel, a left panel, a right panel, and a front end panel 210. In a state in which the drawer 200 is in the closed position, the front end plate 210 of the drawer 200 may seal the opening of the tub 100 such that the inside of the tub 100 forms a closed storage environment, that is, such that the storage space 201 of the drawer 200 is closed in the accommodating compartment 101, so that the drawer 200 and the tub 100 together define a fresh-keeping space. In a state that the drawer 200 is pulled out of the tub 100, the storage space 201 of the drawer 200 is exposed to the outside, and the stored objects can be taken and placed.

As shown in conjunction with fig. 3 and 7, in particular, the tub 100 includes a tub outer case 110 and a tub inner 120 disposed inside the tub outer case 110, thereby forming a sandwich space 102 between a top sidewall inner surface of the tub outer case 110 and a top sidewall outer surface of the tub inner 120.

It should be noted that, the barrel casing is used as the outermost layer of the fresh-keeping storage container, a part of the barrel casing may utilize a chamber structural component in the storage compartment of the refrigerator, for example, when the fresh-keeping storage container is disposed at the bottom of the storage compartment of the refrigerator, the bottom wall of the storage compartment of the refrigerator may be used as the bottom plate of the barrel casing. In addition, the top plate of the barrel shell can transversely extend to serve as the top plate of other storage drawers transversely arranged in parallel with the fresh-keeping storage container.

It should be noted that, in other embodiments, the side wall of the tub may not have a space therebetween, that is, the tub may have only one layer of side wall, or the tub may have only a tub liner, and the air supply duct may be formed outside the top side wall of the tub by using other separately provided components. At this time, the air inlet and the return air inlet are formed by the parts forming the air duct.

Referring to fig. 1 to 8, a top wall front end of the tub 100 is formed with an air supply hole 105 communicating with the air supply duct 10. The front end panel 210 of the drawer 200 includes a front panel 211 and an end panel wind housing 212. An end plate fan housing 212 is provided inside the panel 211, the end plate fan housing 212 protruding from the panel 211 toward the inside of the drawer 200, the end plate fan housing 212 defining the ventilation duct 20. The top end of the end plate fan housing 212 has a wind receiving hole 202. When the drawer 200 is in the closed position, the cool air introduced into the air supply duct 10 from the air inlet 103 can flow out of the air supply hole 105 and flow into the air passage 20 from the air receiving hole 202.

The air duct may be defined by the end plate cover and the panel together, or may be formed by the end plate cover alone (i.e., the end plate cover has a side wall that is bonded to the inner side of the panel). In addition, the end plate fan cover can be a part which is formed separately and then assembled on the drawer, or can be a part which is formed integrally with the drawer. And, the left side wall, the right side wall and the bottom side wall of the end plate fan housing can be directly formed by the left side wall, the right side wall and the bottom side wall of the drawer.

Referring to fig. 8 and 9, the tub 100 further includes an end plate fitting 130, wherein the end plate fitting 130 is provided at a front end of the tub 100, surrounds an opening of the accommodating compartment 101, and is assembled with the tub outer case 110 and the tub inner 120, thereby closing the supply air duct 10. Meanwhile, the air supply hole 105 is formed in the end plate fitting 130, so that the air flow in the air supply duct 10 can flow out of the air supply hole 105.

It should be noted that in other embodiments, the tub may not be provided with an end plate mating member. In this case, the air-blowing hole may be formed at a portion where the front end of the tub outer case is bent toward the tub liner, or at a portion where the front end of the tub liner is bent toward the tub outer case.

Referring to fig. 3, the ratio of the height of the air duct 30 to the height of the storage space 201 is one percent or more and one tenth or less. Specifically, the ratio of the distance between the outer surface of the bottom sidewall of the drawer 200 and the inner surface of the bottom sidewall of the tub 100 to the height of the storage space 201 is one percent or more and one tenth or less. As shown in the figure, the height of the cooling air duct 30 is H, and the height of the storage space 201 is H, i.e., H/H is one percent or more and one tenth or less. For example, it may be one hundredth, one fiftieth, one twentieth, one tenth, etc.

Illustratively, the height of the cooling air duct 30 is 5 mm, the height of the storage space 201 is 500 mm, and the ratio is one hundredth. Alternatively, the height of the air duct 30 is 10 mm, the height of the storage space 201 is 300 mm, and the ratio is one-thirtieth. Alternatively, the height of the air duct 30 is 20 mm, the height of the storage space 201 is 200 mm, and the ratio is one tenth.

In the solution of this embodiment, the air duct 30 is disposed between the bottom sidewall of the drawer 200 and the bottom sidewall of the tub 100, so that the ratio of the height of the air duct 30 to the height of the storage space 201 is greater than or equal to one hundredth and less than or equal to one tenth. The cold air can flow through the cold air duct 30 to exchange heat with the storage space 201, so that the storage space 201 is refrigerated, and the cold air can not directly blow food materials placed in the storage space 201, so that the food materials are prevented from being frozen down due to the fact that the temperature of the food materials is too low. In addition, the ratio of the height of the cold air duct 30 to the height of the storage space 201 is between one hundredth and one tenth, which is conducive to ensuring that the cold air volume in the cold air duct 30 and the storage space 201 have better heat exchange efficiency, thereby ensuring better refrigeration efficiency at least for the effective storage area of the storage space 201.

Preferably, the ratio of the height of the air duct 30 to the height of the storage space 201 is equal to or greater than one fifth and equal to or less than one tenth. For example, it may be one fiftieth, one fortieth, one thirtieth, one twentieth, one tenth, etc.

Further, as shown in fig. 3, the ratio of the height of the cooling air duct 30 to the air intake of the fresh storage container is greater than or equal to one fifth and less than or equal to two fifths. For example, it may be one fiftieth, one fortieth, one thirtieth, one twentieth, one tenth, one fifth, etc. The height unit of the cooling air duct 30 is meter, and the unit of the air inlet is cubic meter/minute. Specifically, the height of the cool air duct 30 is h. The air intake is the air intake of the fresh-keeping storage container from the air inlet 103 every minute.

Illustratively, the height of the cool air transfer duct 30 is 0.005 meters, the air intake is 0.25 cubic meters per minute, and the ratio is one fiftieth. Alternatively, the height of the air duct 30 is 0.01 m, the air intake is 0.5 cubic meters per minute, and the ratio is one fiftieth. Alternatively, the height of the air duct 30 is 0.008 m, the air intake is 0.02 cubic meters per minute, and the ratio is two fifths. Alternatively, the height of the air duct 30 is 0.02 m, the air intake is 0.05 cubic meters per minute, and the ratio is two fifths. Alternatively, the height of the cool air duct 30 is 0.01 m. The air intake was 0.4 cubic meters per minute, and the ratio was forty-one. Alternatively, the height of the air duct 30 is 0.015 m, the air intake is 0.3 cubic meters per minute, and the ratio is one twentieth.

By setting the ratio of the height of the cold air transfer duct 30 to the air intake to be more than or equal to one fifth and less than or equal to two fifths, the space of the cold air transfer duct 30 is matched with the air intake, so that the cold air transfer duct 30 provides sufficient flowing space for cold air, and smooth flowing of the cold air in the cold air transfer duct 30 is facilitated.

Preferably, the ratio of the height of the cold air duct 30 to the air intake of the fresh storage container is greater than or equal to one third and less than or equal to one tenth. For example, it may be one-thirtieth, one-twentieth, one-tenth, etc.

Further, the air inlet set range of the fresh-keeping storage container is more than or equal to 0.02 cubic meter/min and less than or equal to 0.5 cubic meter/min. That is, the fresh storage containers are configured such that the amount of air entering from the air intake 103 per minute is 0.02 cubic meters to 0.5 cubic meters. For example, it may be 0.02 cubic meter/min, 0.1 cubic meter/min, 0.2 cubic meter/min, 0.3 cubic meter/min, 0.4 cubic meter/min, 0.5 cubic meter/min. Preferably, the air inlet set range of the fresh-keeping storage container is more than or equal to 0.2 cubic meter/min and less than or equal to 0.5 cubic meter/min. For example, 0.1 cubic meter/min, 0.15 cubic meter/min, 0.2 cubic meter/min, 0.25 cubic meter/min, 0.35 cubic meter/min, 0.45 cubic meter/min, 0.5 cubic meter/min.

By setting the air inlet setting range of the fresh-keeping storage container to be more than or equal to 0.02 cubic meters per minute and less than or equal to 0.5 cubic meters per minute, the fresh-keeping storage container is effectively ensured to have enough air inlet and the refrigeration efficiency of the storage space 201 is ensured.

Referring to fig. 3, the height of the cool air duct 30 is 5 mm or more and 20 mm or less. Specifically, the design range of h is 5 mm to 20 mm. For example, it may be 5 mm, 10 mm, 15 mm, 20 mm, etc. By designing the height of the cool air transfer duct 30 to be 5 mm or more and 20 mm or less, the cool air can smoothly flow through the height of the cool air transfer duct 30. Meanwhile, the height of the cold air transmission duct 30 is not too high, so that the heat exchange effect of the cold air at the bottom of the cold air transmission duct 30 and the storage space 201 is not affected.

As shown in fig. 3 and 4, further, the fresh storage vessel also includes two magnetic field assemblies 300. Two magnetic field assemblies 300 are provided at the top and bottom sidewalls of the tub 100, respectively. The magnetic field assembly 300 is used for generating a magnetic field in the accommodating compartment 101, so that the food materials placed in the drawer 200 are subjected to the magnetic field, thereby helping to improve the preservation effect of the food materials. Specifically, when the food is in a refrigerating state, the magnetic field can reduce the refrigerating temperature of the food, so that the food can still be kept unfrozen below zero, and the fresh-keeping effect is improved. And when the food is in a frozen state, the magnetic field can avoid the generation of large ice crystals when the food is frozen, and reduce the occurrence of the condition that the food cells are punctured by the large ice crystals, thereby reducing the juice loss of the food and being beneficial to maintaining the quality of the food.

Under the condition that the magnetic field component is arranged on the side wall of the bottom of the barrel body, the magnetic field effect of the magnetic field component on the drawer storage space is guaranteed by designing the height of the cold air duct 30 to be more than or equal to 5 mm and less than or equal to 20 mm.

It should be noted that, in other embodiments, two magnetic field assemblies may be disposed on the left and right sidewalls of the tub. In addition, in other embodiments, the fresh-keeping storage container may also include only one magnetic field assembly, where the magnetic field assembly is disposed on any side wall of the tub.

It should be noted that, in other embodiments, when the tub includes only the tub liner, or the tub side wall has only one layer, the magnetic field assembly may be disposed on the inner surface of the tub side wall, or may be disposed on the outer surface of the tub side wall.

Referring to fig. 3 and 4, further, for the magnetic field assembly 300 provided at the top side wall of the tub 100, the magnetic field assembly 300 is provided in the interlayer space 102 for constituting one duct wall of the supply air duct 10. Specifically, the fresh-keeping storage container further includes an air duct cover 400, the air duct cover 400 is disposed on a side of the magnetic field assembly 300 away from the accommodating compartment 101, and an air supply duct 10 is formed on a side of the air duct cover 400 opposite to the magnetic field assembly 300. The duct cover 400 is made of a thermal insulation material such as thermal insulation foam.

In the solution of this embodiment, the magnetic field assembly 300 is disposed on the tub body 100, and the magnetic field assembly 300 is disposed as one of the air duct walls of the air supply duct 10, so that the magnetic field assembly 300 can generate a magnetic field, thereby improving the fresh-keeping effect of the food materials, and the air supply duct 10 can be formed as the air duct wall, which is helpful for simplifying the structure of the fresh-keeping storage container under the condition of realizing the fresh-keeping of the magnetic field. The duct cover 400 helps to prevent leakage of cold air cooling energy to the outside of the fresh food storage vessel.

It should be noted that in other embodiments, the magnetic field assembly may be disposed on the inner or outer surface of the sidewall, i.e., not disposed in the interlayer.

As shown in fig. 10, the magnetic field assembly 300 includes a shim plate 310 and a source magnet 320. The source magnet 320 is used to generate a magnetic field. The shim plate 310 is disposed on a side of the source magnet 320 facing away from the receiving chamber 101.

The shim plate 310 is made of a magnetically conductive material, such as silicon steel. The source magnetic unit 320 has a structure composed of a permanent magnet 321 and an electromagnetic coil 322. The permanent magnet sheet 321 is disposed at a side of the magnetic homogenizing plate 310 facing the accommodating compartment 101, and the electromagnetic coil 322 is disposed at a side of the permanent magnet sheet 321 facing the accommodating compartment 101. That is, the shim plate 310, the permanent magnet pieces 321, and the electromagnetic coil 322 are arranged in a stacked manner from top to bottom. The shim plate 310 can guide the magnetic field generated by the source magnet 320 such that the magnetic field is more uniformly distributed throughout the receiving chamber 101.

The surface of the magnetic field assembly 300 opposite to the duct cover 400, that is, the surface of the shim plate 310 opposite to the duct cover 400, that is, the opposite side of the shim plate 310 to the duct cover 400 defines the supply air duct 10.

The magnetic field assembly 300 includes a shim plate 310 and permanent magnet pieces 321, the shim plate 310 and the air duct cover 400 defining an air duct. In the process of cold air flowing through the air duct, the magnetic homogenizing plate 310 can play a role in homogenizing temperature, and is beneficial to uniformly cooling in the accommodating compartment 101. In addition, since the heat conduction effect of the magnetic homogenizing plate 310 is good, the temperature in the accommodating chamber 101 is easily reduced too fast to freeze the food due to the formation of the air channel by the magnetic homogenizing plate 310. However, because the heat conduction effect of the permanent magnet sheet 321 is poor, the even magnetic plate 310 and the permanent magnet sheet 321 are mutually matched, so that the accommodating chamber 101 can be cooled uniformly and not cooled too fast, the cooling effect is improved, and unexpected effect is achieved.

It should be noted that, in other embodiments, the source magnetic member may be a permanent magnet sheet alone, or an electromagnetic coil alone.

As shown in fig. 3, 4 and 10, the fresh-keeping container further includes two magnetic conductive members 500. The two magnetic conductive members 500 are disposed on the left and right sidewalls of the tub 100, respectively. The two ends of the magnetic conductive member 500 are respectively connected with the magnetic homogenizing plates 310 in the two magnetic field assemblies 300, so that the two magnetic field assemblies 300 and the two magnetic conductive members 500 form an annular magnetic field loop together, the magnetic field utilization rate is improved, and the influence of the magnetic field on external components is reduced.

It should be noted that, in other embodiments, the two magnetic field assemblies may be disposed on the left and right sidewalls of the tub, and the two magnetic conductive members may be disposed on the top and bottom sidewalls, respectively.

As shown in fig. 11 and 12, the bottom side wall of the end plate fan housing 212 is provided with four air outlet holes 203. Corresponding through holes are also formed in the bottom side wall of the drawer 200, so that air flow in the air passing duct 20 flows out of the air outlet 203 and flows into the air passing duct 30 through the through holes in the bottom side wall of the drawer 200.

Wherein, an air outlet sets up the left end at end plate fan housing 212 bottom side wall, and an air outlet sets up the right-hand member at end plate fan housing 212 bottom side wall, and an air outlet sets up the middle part at end plate fan housing 212 bottom side wall, and an air outlet sets up between the air outlet of end plate fan housing 212 one end of keeping away from the air intake and the air outlet in the middle.

Specifically, the end plate fan housing 212 is located at an end far from the central axis of the air inlet 103 in a transverse direction perpendicular to the central axis of the air inlet 103. That is, the end of the end plate fan housing 212 far from the air inlet 103 has a larger air outlet area relative to the end close to the air inlet 103, so that the bottom air outlet of the end plate fan housing 212 is more uniform.

It should be noted that, in other embodiments, the end plate fan housing may also be provided with an air outlet, for example, an elongated air outlet extending in the left-right direction. Two, three or five equal numbers of air outlets may also be provided.

Referring to fig. 4, 5 and 7, specifically, an air vent 106 is formed at a position of the rear sidewall of the tub inner 120 near the top end, and a longitudinally extending air vent 40 is formed between the rear sidewall of the tub inner 120 and the rear sidewall of the tub outer 110, and the top end of the air vent 40 communicates with the air return 104. The cool air flows from the cool air transfer duct 30 to the rear end of the drawer 200, then flows upwards to the air passing hole 106, flows into the air passing duct 40 from the air passing hole 106, then flows to the air return opening 104 along the air passing duct 40, and finally flows out from the air return opening 104.

In summary, the air path inside the fresh-keeping storage container is configured to: the air flow enters the rear end of the air supply duct 10 defined in the top wall of the tub 100 from the air inlet 103, and then flows through the air supply duct 10 from the rear to the front. At the front end of the supply duct 10, air flows through the supply hole 105 and the air receiving hole 202 into the top end of the wind passing duct 20 defined in the front end plate 210 of the drawer 200, and then flows through the wind passing duct 20 from top to bottom. At the bottom end of the air passing duct 20, air flows into the cool air passing duct 30 between the bottom plate of the drawer 200 and the bottom wall of the tub 100, and then flows through the cool air passing duct 30 from front to back. At the connection position of the rear end of the bottom plate of the drawer 200 and the rear plate of the drawer 200 (i.e., the rear end of the cooling air duct 30), air flow enters the gap between the rear plate of the drawer 200 and the rear wall of the tub 100. And then flows from the air outlet 106 into the air outlet duct 40, and the air flow finally reaches the air return opening 104 along the air outlet duct 40.

The internal air path of the fresh-keeping storage container surrounds the whole fresh-keeping storage container for a circle, and can realize sufficient heat exchange under the condition that the fresh-keeping storage space is not in direct contact with stored objects, so that the fresh-keeping storage container is uniformly refrigerated and cooled.

In addition, the internal air path of the fresh-keeping storage container is also suitable for the temperature characteristics of the refrigerating air flow. In the flowing process of the refrigerating airflow, the refrigerating airflow exchanges heat step by step, and the temperature of the refrigerating airflow rises gradually. The air flow temperature of the air supply duct 10 is the lowest, and the air supply duct 10 is formed inside the top wall of the tub 100, and the cooling capacity is conducted downward from the top wall of the tub 100. The stored objects are relatively far from the top wall of the tub 100, and the heat transfer efficiency is the worst. In the over-air duct 20, the drawer end plate also has a weaker heat transfer efficiency than the drawer bottom plate. The gap between the drawer bottom plate and the bottom wall of the barrel body is used as a cold air transmission channel 30, and the cold air quantity exchanges heat with the drawer bottom plate, so that the heat exchange efficiency is highest. That is, as the temperature of the air flow increases, the heat exchange efficiency of each air path section is relatively increased, which makes the temperatures of each position of the fresh-keeping storage space substantially equivalent.

As shown in fig. 13 and 14, in one embodiment, the refrigerator includes a case 1 and the fresh storage container 2 of any of the above embodiments. The box body 1 is internally provided with a storage compartment 11, and the fresh-keeping storage container 2 is arranged in the storage compartment 11.

It should be noted that, the storage compartments of the refrigerator are usually plural, so as to implement different functions. Such as a refrigerated storage compartment, 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 of the embodiment is an air-cooled refrigerator, an air path system is arranged in the refrigerator body 1, cooling air which is subjected to heat exchange by a heat exchanger (evaporator) is sent to the storage compartment through the air supply opening of the refrigerator body by using a fan, and then the cooling air is returned to the air duct through the air return opening of the refrigerator body, so that circulating air cooling is realized. 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 utility model of the present 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-keeping storage containers may be disposed in the refrigerator of the present embodiment. In some alternative embodiments, the fresh-keeping storage container can be arranged in one or more of the storage compartments, and long-time high-quality cold fresh preservation of food materials such as meat, fish and the like is realized through magnetic field and temperature regulation. For example, the fresh storage container may be disposed within any one of a refrigerated storage compartment, a frozen storage compartment, a temperature change storage compartment. For example, the fresh-keeping storage containers can be arranged in a plurality of the refrigerating storage compartments, the freezing storage compartments and the variable-temperature storage compartments at the same time, that is, the fresh-keeping storage containers are respectively arranged in a plurality of different storage compartments at the same time. For another example, a plurality of fresh-keeping storage containers can be simultaneously arranged in one storage compartment according to the requirement.

Fig. 14 shows an example of a fresh food storage vessel 2 disposed within a refrigerated compartment. Other storage drawers can be arranged in the storage compartment besides the fresh-keeping storage container, for example, fig. 14 shows an example of three other drawer-type storage containers in the fresh-keeping storage compartment, wherein one drawer-type storage container is transversely arranged in parallel with the fresh-keeping storage container 2.

The refrigerator of the embodiment is beneficial to the production of the refrigerator by configuring the magnetic field on the fresh-keeping storage container which is arranged in the compartment of the refrigerator. Of course, the refrigerator can realize magnetic field auxiliary storage of food materials, and can realize non-freezing refrigeration of the food materials below zero when in refrigeration, so that the fresh-keeping effect of the food materials is improved. During freezing, the magnetic field is beneficial to reducing the size of ice crystals generated in the food material, namely small ice crystals are generated in the food material, so that the condition that large ice crystals puncture the cells of the food material is reduced, and the quality of the food material is favorably maintained.

In other embodiments, the container may be disposed on the refrigerator door, preferably, on the inner side of the door when the container is small.
