As shown in fig. 1 to 7, in one embodiment, the fresh storage vessel includes a tub 100 and a drawer 200. The tub 100 defines a receiving compartment 101, and a continuous supply air 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 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-keeping storage container.

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 return 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 further provided with an air return port 104.

The supply air duct 10, the ventilation air duct 20, and the return air duct 30 together constitute an air path surrounding the storage space 201. Flows along the supply air duct 10 and enters the over-air duct 20, flows along the over-air duct 20 and enters the return air duct 30, and finally flows out of the container from the return air inlet 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 9, 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. Or the compartment top wall may serve as the top side wall of the tub enclosure. 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 7, 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 plane in which the outlet of the air-blowing hole 105 is located is inclined toward the top of the tub 100 in a direction away from the rear end of the tub 100. The plane in which the inlet of the air-receiving hole 202 is located is inclined toward the bottom of the drawer 200 in a direction away from the panel 211.

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. 7 and 10, 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. In addition, the continuous air duct 10, i.e., the cool air, does not flow out of the air duct 10 before flowing into the air hole 105 after entering the air duct 10.

It should be noted that the end plate matching member 130 may not be provided to the tub 100. 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. 7 and 8, in detail, a portion of the tub 100 for forming the air-feed hole 105 (i.e., a portion of the end plate fitting 130 for forming the air-feed hole 105) is inclined toward the top of the tub 100 in a direction away from the rear end of the tub 100, that is, in a direction toward the opening of the tub 100. The plane in which the outlet of the air-sending hole 105 is located is the plane in which the bottom side face of the portion is located, that is, the plane in which the side face facing away from the air-sending duct 10 is located.

The top side wall of the end plate wind housing 212 is inclined toward the bottom of the drawer 200 in a direction away from the panel 211, that is, toward the bottom of the drawer 200 in a direction in which the front end of the drawer 200 is directed toward the rear end. The plane in which the inlet of the air receiving hole 202 is located, i.e., the plane in which the top end face of the end plate fan housing 212 is located, i.e., the plane in which the top side wall of the end plate fan housing 212 is located away from the side face of the air passing duct 20.

As shown in fig. 3 and 7, the plane of the air supply hole 105 and the plane of the air receiving hole 202 are inclined in the same direction, i.e. both are inclined toward the bottom of the fresh food storage container in the front-to-back direction, as viewed from the whole of the fresh food storage container.

In the solution of the present embodiment, by tilting the plane of the outlet of the air supply hole 105 toward the top of the tub 100 in a direction away from the rear end of the tub 100, the plane of the inlet of the air receiving hole 202 is tilted toward the bottom of the drawer 200 in a direction away from the panel 211. In the process that cold air enters the air passing duct 20 from the air supply duct 10, the flowing route of the cold air is in a parabolic shape as a whole, so that the cold air track is not at a vertical angle, and the cold air flows between the air supply hole 105 and the air receiving hole 202 more smoothly, thereby being beneficial to reducing wind loss and effectively avoiding cold energy concentration. In addition, the inclined surface at the top of the end plate fan housing 212 is also beneficial to reducing the probability of foreign matters falling into the over-air duct 20.

Referring to fig. 7 and 8, the included angle between the plane of the outlet of the air supply hole 105 and the vertical direction is 10 degrees or more and 80 degrees or less. The included angle between the plane where the inlet of the air receiving hole 202 is located and the vertical direction is greater than or equal to 10 degrees and less than or equal to 80 degrees.

Referring to fig. 7 and 8, the angle a, which is the angle between the plane in which the outlet of the air blowing hole 105 is located and the vertical direction, is the designed value of the angle a, and the designed value range is 10 degrees or more and 80 degrees or less. For example, it may be 10 degrees, 20 degrees, 26 degrees, 30 degrees, 33 degrees, 40 degrees, 45 degrees, 50 degrees, 54 degrees, 60 degrees, 68 degrees, 70 degrees, 73 degrees, 80 degrees. Preferably, the included angle between the plane of the outlet of the air supply hole 105 and the vertical direction is greater than or equal to 60 degrees and less than or equal to 75 degrees. For example, 60 degrees, 62 degrees, 64 degrees, 70 degrees, 72 degrees, 75 degrees may be used.

Referring to fig. 7 and 8, the included angle b between the plane where the inlet of the air receiving hole 202 is located and the vertical direction, that is, the designed value of the angle b ranges from 10 degrees or more to 80 degrees or less. For example, it may be 10 degrees, 20 degrees, 26 degrees, 30 degrees, 33 degrees, 40 degrees, 45 degrees, 50 degrees, 54 degrees, 60 degrees, 68 degrees, 70 degrees, 73 degrees, 80 degrees. Preferably, the included angle between the plane where the inlet of the wind receiving hole 202 is located and the vertical direction is greater than or equal to 60 degrees and less than or equal to 75 degrees. For example, 60 degrees, 62 degrees, 64 degrees, 70 degrees, 72 degrees, 75 degrees may be used.

The included angle between the plane where the outlet of the air supply hole 105 is located and the vertical direction is greater than or equal to 10 degrees and less than or equal to 80 degrees, and the included angle between the plane where the inlet of the air receiving hole 202 is located and the vertical direction is greater than or equal to 10 degrees and less than or equal to 80 degrees, so that the end plate fan housing 212 and the barrel body 100 are convenient to produce on the basis of ensuring smooth airflow.

In addition, in the present embodiment, the plane in which the inlet of the air receiving hole 202 is located is parallel to the plane in which the inlet of the air receiving hole 202 is located, that is, the angle between the plane in which the outlet of the air supplying hole 105 is located and the vertical direction is equal to the angle between the plane in which the inlet of the air receiving hole 202 is located and the vertical direction. For example, the angle between the plane of the outlet of the air hole 105 and the vertical direction is 75 degrees from the angle between the plane of the inlet of the air hole 202 and the vertical direction.

As shown in fig. 7 and 8, the distance from any point in the outlet region of the air blowing hole 105 to the plane on which the inlet of the air receiving hole 202 is located is 3 mm or more and 20 mm or less. That is, any point in the outlet of the air blowing hole 105 is perpendicular to the plane in which the inlet of the air receiving hole 202 is located, and the length of the perpendicular (the distance d in fig. 8) is 3 mm or more and 20 mm or less. For example, it may be 3 mm, 5 mm, 8 mm, 10 mm, 15 mm, 20 mm, etc. Preferably, the distance is 5 mm or more and 15 mm or less. For example, it may be 5 mm, 12 mm, 14 mm, 15 mm, etc. Preferably, 5 mm is used.

By making the distance from any point in the outlet area of the air supply hole 105 to the plane where the inlet of the air receiving hole 202 is located 3mm or more and 20mm or less, on the one hand, the air leakage is prevented from being serious due to the excessively large distance between the air supply hole 105 and the air receiving hole 202. On the other hand, the friction between the end plate fan housing 212 and the barrel body 100 caused by the fact that the air sending holes 105 and the air receiving holes 202 are too close to each other in the moving process of the drawer 200 is avoided.

Referring to fig. 7, the area of the inlet of the air receiving hole 202 is equal to or larger than the area of the outlet of the air sending hole 105. The projection of the outlet region of the air blowing hole 105 onto the plane on which the inlet of the air receiving hole 202 is located falls within the inlet region of the air receiving hole 202. Preferably, the ratio of the area of the inlet of the air receiving hole 202 to the area of the outlet of the air blowing hole 105 is 2 or less. With the above configuration, it is advantageous to ensure that the cool air flows into the over-air duct 20 as much as possible.

In addition, the depth of the wind receiving hole 202 is preferably 1mm or more and 5mm or less. For example, it may be 1mm, 2mm, 3mm, 4 mm, 5mm, etc. Preferably 3 mm.

As shown in fig. 6 and 7, a plurality of partition ribs 2121 are provided in the wind receiving hole 202, and the partition ribs 2121 extend in the left-right direction of the drawer 200. Specifically, both ends of each of the partition ribs 2121 are respectively connected to the left and right hole walls of the air receiving hole 202, and the plurality of partition ribs 2121 are distributed along the front-rear direction of the drawer 200, thereby partitioning the air receiving hole 202 into a plurality of regions. Preferably, the spacing between two adjacent separation ribs 2121 is 1 mm or more and 3 mm or less. For example, it may be 1 mm, 2 mm, 3 mm, etc.

By providing a plurality of separation ribs 2121 in the wind receiving hole 202, the wind receiving hole 202 is divided into a plurality of areas, which is beneficial to reducing the condition that the airflow generates vortex in the wind receiving hole 202. By controlling the spacing between the separation ribs 2121, it is advantageous to prevent foreign matter from falling into the over-air duct 20.

Further, as shown in fig. 7, a smooth curved surface is formed on a side of the partition 2121 facing the top of the end plate fan housing 212. Thereby helping to allow cool air to more smoothly flow through the separating rib 2121 to enter the over-air duct 20.

The wind receiving hole 202 may or may not have a rib perpendicular to or intersecting with the partition rib 2121.

Referring to fig. 7 and 10, a single reinforcing rib 140 and a plurality of reinforcing ribs 150 are provided in the air supply hole 105, the reinforcing rib 140 extending in the left-right direction of the tub 100, and the reinforcing ribs 150 extending in the front-rear direction of the tub 100. The reinforcing rib 150 is connected to the reinforcing rib 140.

Wherein the reinforcing ribs 150 are in the form of a sheet. Extending in the front-rear direction of the tub 100 in the lateral direction. In the longitudinal direction, a part of the air flow path is located in the air supply hole 105, and a part of the air flow path extends into the air supply duct 10 and extends out of the air supply hole 105. That is, the reinforcing rib 140 and one reinforcing rib 150 form a cross-shaped structure for dividing the air flow to prevent the generation of vortex in the air supply hole 105.

Referring to fig. 1 and 7, the ratio of the ventilation area of the air supply hole 105 to the ventilation area of the air intake 103 is 1 or more and 2 or less. Ensuring the flow rate of the cold air and helping to avoid turbulence caused by too high flow rate of the cold air in the air supply hole 105.

Referring back to fig. 3, 5 and 7, the fresh storage vessel also includes a seal 300. The sealing member 300 is provided inside the top wall of the accommodating compartment 101, and the sealing member 300 extends in the left-right direction of the tub 100. Wherein the drawer 200 in the closed position has the front end plate 210 abutted against the front end of the tub 100 and abutted against the seal 300, and the air supply hole 105 and the air catching hole 202 are located between the contact position of the front end plate 210 with the tub 100 and the contact position of the front end plate 210 with the seal 300. Specifically, the drawer 200 in the closed position has the inner side of the panel 211 abutted against the front end of the tub 100, and the side of the end plate fan housing 212 facing the inside of the drawer 200 abutted against the seal 300.

Referring to fig. 3 and 7, when the drawer 200 is in the closed position, the inner side of the panel 211 and the front end of the end plate fitting 130 are abutted, thereby functioning to close the accommodating compartment 101. The seal 300 and the end plate wind cap 212 abut and act to reduce the flow of cold wind into the storage space 201. In other words, the panel 211, the end plate mating member 130 and the sealing member 300 together define a relatively closed passageway between the small section of the air supply hole 105 and the air receiving hole 202, so that cold air can flow into the air passing duct 20 as much as possible, thereby reducing air leakage into the storage space 201 and avoiding the temperature of the stored articles from falling too rapidly.

In the aspect of the present embodiment, by providing the sealing member 300 inside the top wall of the tub 100, the front end plate 210 of the drawer 200 is abutted against the front end of the tub 100 and is abutted against the sealing member 300 when the drawer 200 is in the closed position. The air supply hole 105 and the air receiving hole 202 are located between the contact position of the front end plate 210 and the tub 100 and the contact position of the front end plate 210 and the sealing member 300, that is, the panel 211, the end plate matching member 130 and the sealing member 300 together define a relatively closed passageway between the small section of air supply hole 105 and the air receiving hole 202, so that cold air can flow into the air passing duct 20 as much as possible, thereby reducing air leakage into the storage space 201 and avoiding freezing caused by too fast food temperature drop.

As shown in conjunction with fig. 11 and 12, in particular, the seal 300 includes a support portion 310 and a seal portion 320. The support portion 310 is for connection with the tub 100. The sealing portion 320 has one end connected to the supporting portion 310 and the other end adapted to abut against the end plate fan housing 212. The support part 310 is made of a relatively hard material (e.g., PP (polypropylene) material) so as to be firmly coupled with the tub 100. The seal 320 is made of a softer material (e.g., TPE (Thermo Plastic Elastomer, thermoplastic elastomer) material, rubber, etc.) to facilitate deformation in contact with the endplate bellows 212 to achieve a better seal.

Referring to fig. 11 to 13, the supporting portion 310 is formed with an engagement groove 301, and the tub 100 is provided with an engagement rib 160. The fitting rib 160 is inserted into the fitting groove 301 to connect the sealing member 300 with the tub 100. Specifically, the support portion 310 has a generally "U" shape in cross section, and the mating groove 301 is a "U" shaped recess.

By adopting the assembly mode of matching the matching groove 301 and the matching rib 160, the assembly process of the sealing element 300 and the barrel body 100 is more convenient, and the sealing element 300 can be detachably connected with the barrel body 100, so that the sealing element 300 is convenient to replace.

It should be noted that, in other embodiments, the sealing member 300 may be assembled to the tub 100 by an adhesive, a screw fastening, or the like.

As shown in fig. 3 and 11 to 13, one end of the sealing portion 320 is in contact with the notch end of one side wall of the fitting groove 301, and the other end extends in the opening direction of the fitting groove 301. Accordingly, correspondingly, the fitting rib 160 provided on the tub 100 is formed to extend forward and backward. In other words, the engagement groove 301 of the support part 310 is caught on the engagement rib 160 in the backward-to-forward direction of the tub 100. Alternatively, after the sealing member 300 is assembled with the tub 100 in place, the opening of the fitting groove 301 is oriented to coincide with the opening of the accommodating compartment 101.

Because the sealing part 320 receives the pressure of the end plate fan housing 212 directed to the rear of the tub body 100 in the contact process of the end plate fan housing 212 and the sealing member 300, by connecting one end of the sealing part 320 with the notch end of one side wall of the mating groove 301 and extending the other end toward the opening direction of the mating groove 301, when the sealing part 320 receives the pressure, the pressure can be transferred to the supporting part 310, and then the mating groove 301 can offset part of the pressure in a slight expansion deformation manner, thereby reducing the pressure burden of the joint of the sealing part 320 and the supporting part 310, and being beneficial to improving the service life of the sealing member 300.

In other embodiments, one end of the sealing portion may be connected to the outside of the groove bottom wall of the mating groove, and the other end may extend in a direction away from the opening of the mating groove. In addition, the assembly direction of the matching groove and the matching rib can be along the top-bottom direction of the barrel body.

As shown in fig. 11 to 13, further, the sealing portion 320 is a flexible fin, the sealing portion 320 is curved, and a side of the sealing portion 320 near the supporting portion 310 is a curved convex side. Specifically, with reference to the end of the sealing portion 320 that is in contact with the support portion 310, the entirety of the curved sealing portion 320 is located on the side of the contacting side wall that is away from the mating groove 301. The other end of the sealing portion 320 is spaced apart from the end of the sealing portion 320 in contact with the supporting portion 310 in both the lateral and longitudinal directions. And the two ends are bent. The side of the sealing portion 320 near the supporting portion 310 is a curved convex side, in other words, a concave side of the curved sealing portion 320 is seen from the view of the mating groove 301 from the front of the notch of the mating groove 301.

By providing the sealing portion 320 as a curved flexible fin, the side of the sealing portion 320 near the support portion 310 is a curved convex side. During the contact of the sealing portion 320 with the end plate fan housing 212, the end of the sealing portion 320 remote from the support portion 310 is brought into contact with the end plate fan housing 212. As the drawer 200 continues to close, the sealing portion 320 is pressurized by the end panel housing 212, because of the special configuration of the sealing portion 320, the sealing portion 320 has two points that are easily deformed, one being the junction of the sealing portion 320 and the support portion 310, and the other being the middle of the sealing portion 320. On the one hand, the sealing part 320 is easier to deform so as to buffer the pressure applied to the sealing part 320, thereby prolonging the service life of the sealing part 320. On the other hand, the sealing portion 320 can maintain the bending direction of the base in the process of being extruded, but the bending degree is increased, so that the guiding direction of the sealing portion 320 for the cold air is maintained towards the side where the air receiving hole 202 is located, and the smooth flow of the air flow is facilitated.

In other embodiments, the sealing portion may be an elastic block.

As shown in fig. 14 and 15, 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 returning 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 9, 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 return air 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 return air inlet 104 along the air passing duct 40, and finally flows out from the return air inlet 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 over-air duct 20, air flows into the return air duct 30 between the bottom plate of the drawer 200 and the bottom wall of the tub 100, and then flows through the return air 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 return 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 return air duct 30, and the cooling capacity and the drawer bottom plate exchange heat, 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.
