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.

A drawer 200 is drawably provided in the accommodating compartment 101, the drawer 200 defining a storage space 201. The front end plate 210 of the drawer 200 defines the ventilation duct 20. The cold air duct 30 is defined between the bottom of the drawer 200 and the inner surface of the bottom sidewall of the tub 100. The rear end of the tub 100 is formed with an air inlet 103 communicating with the air supply duct 10 so that cool air enters the air supply duct 10 from the outside of the fresh air storage container, and air flow from the air inlet 103 is guided to the air supply duct 20 through the air supply duct 10. The rear end of the tub 100 is further provided with an air return port 104.

The supply air duct 10, the over-air duct 20, and the cool air duct 30 together constitute an air path surrounding the storage space 201. Flows along the air supply duct 10 and enters the air passing duct 20, flows along the air passing duct 20 and enters the cold air transferring duct 30, and finally flows out of the container from the air return opening 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.

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.

As shown in fig. 3, the top side wall of the tub 100 includes an inner top wall and an outer top wall, between which an air supply duct 10 is formed. The side of the inner top wall facing the inside of the tub 100 is a continuous surface. Specifically, the top wall of the tub outer case 110 and the top wall of the tub inner 120 together constitute a top side wall of the tub 100. The inner top wall of the tub 100, i.e., the top wall of the tub liner 120, and the outer top wall of the tub 100, i.e., the top wall of the tub outer case 110. That is, the interlayer space 102 is formed between the inner top wall and the outer top wall of the tub 100.

The side of the inner top wall of the tub 100 facing the inside of the tub 100 is a continuous surface, in other words, the side of the inner top wall facing the accommodating compartment 101 is a continuous surface. Specifically, a substantial portion of the inner top wall, i.e., the portion of the inner top wall that covers the storage space 201 when the drawer 200 is in the closed position, is free of through holes extending through the top-bottom direction of the inner top wall.

In the solution of the present embodiment, the air supply duct 10 is provided on the top side wall of the tub 100, and a surface of the inner top wall of the tub 100 facing the inside of the tub 100 is provided as a continuous surface. During the use of the tub 100, the drawer 200 may be installed inside the tub 100, and cool air enters the supply duct 10 through the air inlet 103. Because the inner top wall of the tub body 100 is a continuous surface facing the inside of the tub body 100, cold air cannot leak into the tub body 100 when the air supply duct 10 flows, so that the temperature inside the tub body 100 is prevented from falling too fast, and the stable falling of the temperature inside the tub body 100 is ensured.

Further, as shown in fig. 3, the fresh storage vessel includes a magnetic field assembly 300, the magnetic field assembly 300 being disposed between the inner ceiling wall and the outer ceiling wall, the magnetic field assembly 300 constituting one duct wall of the supply duct 10. The fresh-keeping storage container further comprises an air duct cover plate 400, the air duct cover plate 400 is arranged between the inner top wall and the outer top wall, the air duct cover plate 400 is arranged on one side of the magnetic field assembly 300 away from the inner top wall, and an air supply air duct 10 is formed on the opposite side of the air duct cover plate 400 to the magnetic field assembly 300.

That is, the magnetic field assembly 300 and the duct cover 400 are disposed within the interlayer space 102, i.e., between the tub outer 110 and the top sidewall of the tub liner 120. The magnetic field assembly 300 is disposed on the outer surface of the top sidewall of the tub liner 120, and the duct cover 400 is disposed on the inner surface of the top sidewall of the tub outer case 110.

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.

It should be noted that, in other embodiments, the magnetic field assembly may be disposed on other side walls of the tub, and the air supply duct is defined by other members disposed on the top side wall of the tub.

It should be noted that, in other embodiments, the magnetic field assembly may be disposed inside the inner top wall of the tub.

As shown in fig. 3 and 10 to 11, the air duct cover 400 is configured to form an air duct recess 401 on a side facing the magnetic field assembly 300, the air duct recess 401 extends from a rear end to a front end of the air duct cover 400, and a structural interface 402 is defined at a rear end of the air duct recess 401, and the structural interface 402 is configured to communicate with the air inlet 103. The surfaces of the duct cover plates 400 at both sides of the air path recess 401 are attached to the magnetic field assembly 300, so that the air path recess 401 and the magnetic field assembly 300 define the supply air duct 10.

Specifically, the duct cover 400 has a certain thickness facing the inward wind path recess 401 of the magnetic field assembly 300 and penetrating through the front and rear ends of the duct cover 400. When the duct cover 400 is assembled with the magnetic field assembly 300 in place, the portions of the duct cover 400 on either side of the air path recess 401 contact the magnetic field assembly 300 to form a seal. Also, since the air path recess 401 penetrates opposite ends of the air path cover 400, the air path recess 401 and the magnetic field assembly form the supply air duct 10 extending from the rear end to the front end of the air path cover 400.

By forming the wind path recess 401 in the wind path cover 400, the wind path cover 400 can form three sidewalls of the wind path, and the magnetic field assembly 300 forms the other sidewall of the wind path. Compared with the two opposite side walls of the air duct formed by the air duct cover 400 and the magnetic field assembly 300 and the other two side walls of the air duct formed by other components, the air supply air duct 10 is formed by only using the two components of the air duct cover 400 and the magnetic field assembly 300, thereby further simplifying the structure. Moreover, only the air duct cover plate 400 and the magnetic field assembly 300 need to be sealed, so that the sealing is convenient, and the sealing effect is better.

The sealing between the magnetic field assembly and the air duct cover plate can be direct contact sealing between the magnetic field assembly and the air duct cover plate, or indirect contact sealing through two sealing strips arranged between the magnetic field assembly and the air duct cover plate, wherein the two sealing strips are arranged on two sides of the air supply air duct.

As shown in fig. 10 to 12, three flow dividing ribs 410 are provided in the air supply duct 10, and the flow dividing ribs 410 extend in the front-rear direction of the air supply duct 10 to divide the air supply duct 10 into a plurality of air passages distributed in the left-right direction.

Specifically, three flow dividing ribs 410 are distributed in the left-right direction of the air supply duct 10, dividing the air supply duct 10 into four air passages. Specifically, the duct cover 400 is made of a heat insulating material, such as a foam material. Meanwhile, the shunt rib 410 is formed by protruding a side of the air duct cover 400 facing the magnetic field assembly 300 toward the magnetic field assembly 300. That is, the diverting rib 410 is integrally formed with the duct cover 400.

By providing the flow dividing rib 410 in the air supply duct 10, the air flow entering the air supply duct 10 can be dispersed to the left and right sides, so that the air flow can be distributed more uniformly in the air supply duct 10. And, the diverting rib 410 and the air duct cover plate 400 are integrally formed, so that the air duct cover plate 400 is well supported, and the structural strength of the air duct cover plate 400 is improved.

It should be noted that in other embodiments, the number of the flow dividing ribs may be one, two, four or more.

As further shown in fig. 1 and 13 to 15, the rear top end of the tub 100 has an inclined section 111, and the air intake 103 is formed in the inclined section 111. The inclined direction of the inclined section 111 is directed from the top to the bottom in the front-to-rear direction of the tub 100. One end of the duct cover 400, where the construction interface 402 is formed, is formed with an inclined surface 420 that mates with the inclined section 111, and the construction interface 402 is formed at the inclined surface 420. The inclined surface 420 conforms to the inner surface of the inclined section 111 such that the build interface 402 is aligned with the intake 103.

Specifically, an inclined section 111 is formed on the top wall of the tub outer shell 110 or the outer top wall of the tub body 100. In a state where the duct cover 400 is assembled with the tub enclosure 110 in place, the duct cover 400 is fitted to an inner surface of a top wall of the tub enclosure 110, including a fit between the inclined surface 420 of the duct cover 400 and an inner surface of the inclined section 111. That is, in a state where the duct cover 400 is assembled with the tub housing 110 in place, the inclined direction of the inclined surface 420 of the duct cover 400 is identical to the inclined direction of the inclined section 111. The interface 402 is configured to align with the air inlet 103 such that cool air from outside the fresh container can enter the supply air duct 10 through the air inlet 103.

By providing the inclined section 111 in the tub 100, the air intake 103 is formed in the inclined section 111, thereby facilitating the air supply to the air supply duct 10. And the section of the barrel body 100 provided with the air inlet 103 is in longitudinal assembly relation with the air duct cover plate 400, so that the barrel body 100 and the air duct cover plate 400 are conveniently pressed.

Referring to fig. 13 to 15, the outer case of the tub 100 is formed with a longitudinal extension 112 at the rear end of the inclined section 111, the duct cover 400 is formed with a longitudinal extension 430 engaged with the longitudinal extension 112, and the duct cover 400 and the tub 100 are assembled in place such that the longitudinal extension 430 is adhered to the inner surface of the longitudinal extension 112.

Specifically, the longitudinally extending section 112 is also formed at the top side wall of the tub outer shell 110, and has no rear end of the inclined section 111 and meets the inclined section 111. In a state where the duct cover 400 is assembled with the tub enclosure 110 in place, the duct cover 400 is fitted to an inner surface of a top wall of the tub enclosure 110, including the fit between the longitudinally extending surface 430 of the duct cover 400 and an inner surface of the longitudinally extending section 112. The longitudinally extending surface 430 cooperates with the longitudinally extending section 112 to locate the assembly of the duct cover 400 with the tub enclosure 110.

Referring to fig. 13 to 15, further, a positioning groove 403 is provided at one side of the duct cover 400, and a positioning rib 113 is provided at the inner side of the top wall of the tub housing 110. The positioning groove 403 cooperates with the positioning rib 113 to perform a positioning function for the assembly of the duct cover 400 and the tub housing 110.

Referring to fig. 7 and 16, the top side of the inner top wall is provided with a support rib 121. The support bars 121 support the magnetic field assembly 300. Specifically, the top wall of the tub liner 120 is provided with a raised support rib 121. When the magnetic field assembly 300 is assembled in place in the tub 100, the bottom surface of the magnetic field assembly 300 abuts against the top ends of the support ribs 121. In turn, the magnetic field assembly 300 is supported by the support bars 121.

On the one hand, the supporting ribs 121 can play a role in pressing and supporting the magnetic field assembly 300, so that the magnetic field assembly 300 is more firmly installed, and the magnetic field assembly 300 is prevented from being deviated in the use process. On the other hand, the supporting ribs 121 support the magnetic field assembly 300, so that an air heat insulation layer is formed between the magnetic field assembly 300 and the top wall of the barrel liner 120, and the accommodating chamber 101 is prevented from being cooled too fast.

As shown in fig. 17, 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 interior of the tub 100.

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 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.

The magnetic homogenizing plate is provided with a groove, the permanent magnet sheet is arranged in the groove, and the depth of the groove can be larger than the thickness of the permanent magnet sheet, so that the supporting rib supports the magnetic homogenizing plate; the depth of the groove can also be smaller than the thickness of the permanent magnet sheet, so that the support rib supports the permanent magnet sheet.

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 17, further, the fresh storage vessel is provided with two sets of magnetic field assemblies 300. Two sets of magnetic field assemblies 300 are disposed in the top and bottom sidewalls of the tub 100, respectively. And, the fresh-keeping storage container further comprises two magnetic conduction pieces 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. 18 and 19, 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.
