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 formed in a top sidewall 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. The cold air 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 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. Or the compartment top wall constitutes 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 8, a top sidewall front end of the tub 100 is provided with a wind feed hole 105. 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. So as to guide the air flow entering from the air inlet 103 to the air passing channel 20 through the air supply channel 10, enter the air passing channel 20 through the air supply hole 105 and the air receiving hole 202, and guide the air flow entering from the air receiving hole 202 downwards through the air passing channel 20. The panel 211 is inclined from bottom to top and from front to back, so that the ventilation duct 20 is inclined against the duct wall of the panel 211.

Referring to fig. 1 to 8, in particular, the end plate duct 212 defines the over-air duct 20 together with the panel 211, in other words, the inner surface of the panel 211 constitutes the duct wall against which the over-air duct 20 abuts the panel 211. Accordingly, the panel 211 is tilted such that the over-air duct 20 is tilted against the duct wall of the panel 211. The panel 211 is inclined from bottom to top and from front to back, i.e., the top end of the panel 211 is closer to the rear end of the drawer 200 than the bottom end.

In the solution of the present embodiment, the over-air duct 20 is inclined against the duct wall of the panel 211 by inclining the panel 211 of the drawer 200 from the bottom side to the top side and from front to back. When the cool air flow enters the air passing duct 20 through the air receiving hole 202 at the top end of the end plate fan housing 212, the cool air flow has a forward flowing power, so that the cool air flow entering the air passing duct 20 may strike the front air duct wall of the air passing duct 20, that is, the air duct wall abutting against the panel 211 is inclined. Because the air duct wall of the panel 211 is inclined, the cold air flow can be more smoothly guided downwards, and compared with the vertically arranged panel, the cold air flow impacting the air duct wall at the front side of the air duct 20 can more smoothly flow downwards, so that the turbulence of the cold air is reduced.

It should be noted that, in other embodiments, the over-air duct may be formed by the end plate fan housing alone, that is, the end plate fan housing has a side wall that is bonded to the inner side of the panel, where the over-air duct is bonded to the duct wall of the panel, that is, the side wall where the end plate fan housing is bonded to the panel.

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. 3 and 4, the range of the angle between the panel 211 and the bottom plate of the drawer 200 is 45 degrees or more and 89 degrees or less. Specifically, the included angle between the plane of the inner surface of the panel 211 and the plane of the inner surface of the bottom plate of the drawer 200 is greater than or equal to 45 degrees and less than or equal to 89 degrees. Such as 45 degrees, 50 degrees, 65 degrees, 75 degrees, 80 degrees, 82 degrees, 89 degrees, etc. Preferably, 82 degrees may be selected. Preferably, the angle between the panel 211 and the bottom of the drawer 200 is greater than or equal to 60 degrees and less than or equal to 85 degrees. Such as 60 degrees, 65 degrees, 70 degrees, 75 degrees, 82 degrees, 85 degrees, etc.

Referring to fig. 3 and 4, the side walls of the end plate hoods 212 opposite to the panel 211 are inclined from the bottom side to the top side and from front to back. Specifically, the side wall of the end plate hood 212 opposite to the panel 211 is a side wall for constituting the rear side duct wall of the over-air duct 20, or the rear side wall of the end plate hood 212. The top end of the rear sidewall of the end plate wind housing 212 is closer to the rear end of the drawer 200 than the bottom end.

By tilting the side wall of the end plate housing 212 opposite to the panel 211 from the bottom side to the top side and from front to back, i.e. by making the side wall of the end plate housing 212 opposite to the panel 211 and the panel 211 the same in overall tilting tendency, the air flow in the over-air duct 20 is facilitated to be smoother.

Referring to fig. 3 and 4, the side wall of the end plate fan housing 212 opposite to the panel 211 forms an angle with the bottom plate of the drawer 200 of 45 degrees or more and 89 degrees or less. Specifically, the included angle between the plane of the inner surface of the side wall of the end plate fan housing 212 opposite to the panel 211 and the plane of the inner surface of the bottom plate of the drawer 200 is greater than or equal to 45 degrees and less than or equal to 89 degrees. Such as 45 degrees, 50 degrees, 65 degrees, 75 degrees, 80 degrees, 82 degrees, 89 degrees, etc. Preferably, 85 degrees may be selected. Preferably, the angle between the panel 211 and the bottom of the drawer 200 is greater than or equal to 60 degrees and less than or equal to 85 degrees. Such as 60 degrees, 65 degrees, 70 degrees, 75 degrees, 82 degrees, 85 degrees, etc.

Referring to fig. 3 and 4, the side wall of the end plate fan housing 212 opposite to the panel 211 forms an angle with the bottom plate of the drawer 200 greater than the angle between the panel 211 and the bottom plate of the drawer 200. That is, the inner surface of the rear side wall of the end plate duct 212 is not parallel to the inner surface of the panel 211, so that the width of the ventilation duct 20 in the front-rear direction of the drawer 200 is increased from top to bottom.

By making the angle between the side wall of the end plate duct 212 opposite to the panel 211 and the bottom plate of the drawer 200 larger than the angle between the panel 211 and the bottom plate of the drawer 200, the width of the ventilation duct 20 in the front-rear direction of the drawer 200 is made larger from top to bottom. That is, a larger flow space is provided for the cold air flow beyond the bottom of the air duct 20, so that the flow of the cold air is smooth, and the occurrence of turbulence caused by urgent cold air is reduced.

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.

Referring to fig. 8, a plane in which the outlet of the air supply 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.

Referring to fig. 3 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 8, the inclination trend of the plane of the outlet of the air supply hole 105 and the plane of the inlet of the air receiving hole 202 is consistent from the whole of the fresh food storage container, that is, the fresh food storage container is inclined toward the bottom of the fresh food storage container from the front to the back.

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.

In addition, the panel 211 of the drawer 200 is inclined from bottom to top and from front to back, and has a more consistent inflow angle with the parabolic cold air, so that the diversion effect on the cold air flow is improved, and the cold air flows more smoothly.

Referring to fig. 8 and 10, 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. 8 and 10, 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. 8 and 10, the angle b between the plane of the inlet of the wind receiving hole 202 and the vertical direction is the angle b, 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. 8 and 10, 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, 5mm, 8 mm, 10 mm, 15 mm, 20 mm, etc. Preferably, the distance is 5mm or more and 15 mm or less. For example, it may be 5mm, 12 mm, 14 mm, 15 mm, etc. Preferably, 5mm 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. 8, 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. 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.
