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 is formed with a receiving compartment 101. The top sidewall of the tub 100 is formed with an air supply duct 10. 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.

An air inlet 103 and an air return 104 are formed at the top of the rear end of the tub 100. The air flow entering from the air inlet 103 is guided to the air passing duct 20 via the air supplying duct 10, and the air flow from the air supplying duct 10 is guided to the cool air transferring duct 30 via the air passing duct 20.

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. In this case, the air inlet is formed by the components 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.

As shown in fig. 4, 5 and 7, further, a rear sidewall of the accommodating chamber 101 is formed with a wind outlet 106 so that the refrigerant air flow entering the accommodating chamber 101 flows out of the accommodating chamber 101 through the wind outlet 106. The fresh storage container is configured such that the ratio of the area of the air outlet 106 to the return air volume of the accommodating compartment 101 is five percent or more and two tenth or less.

Specifically, the cold air enters the cold air duct 30, i.e., enters the accommodating compartment 101, and then flows out of the accommodating compartment 101 through the air outlet 106. The amount of return air in the accommodating chamber 101, that is, the amount of air flowing out of the accommodating chamber 101 per minute, is expressed in cubic meters per minute. The area of the air outlet 106 is in square meters. The ratio of the area of the air outlet 106 to the air return volume of the accommodating chamber 101 is equal to or greater than five percent and equal to or less than two tenths. For example, it may be five percent, four percent, three percent, two percent, one fiftieth, one thirtieth, one twentieth, etc.

Illustratively, the return air volume is 0.5 cubic meters per minute, the area of the air outlet 106 is 0.001 square meters, and the ratio is five percent. Alternatively, the return air volume is 0.02 cubic meters per minute, the area of the air outlet 106 is 0.001 square meters, and the ratio is one twentieth. Alternatively, the return air volume is 0.4 cubic meters per minute, the area of the air outlet 106 is 0.02 square meters, and the ratio is one twentieth. Alternatively, the return air volume is 0.4 cubic meters per minute, the area of the air outlet 106 is 0.01 square meters, and the ratio is fortieth.

In the solution of this embodiment, the fresh-keeping storage container is configured such that the ratio of the area of the air outlet 106 to the air return volume of the accommodating compartment 101 is greater than or equal to five percent and less than or equal to two tenths, so that the area of the air outlet 106 can be better adapted to the air return volume of the accommodating compartment 101. Therefore, the cold air flows more smoothly when flowing out of the accommodating compartment 101 through the air outlet 106, and the influence of turbulent flow of the cold air formed by the cold air at the air outlet 106 on the flow of the cold air is avoided.

As shown in fig. 4, 5 and 7, further, an air duct 40 is provided in the rear sidewall of the tub 100, so that the cool air flow entering the accommodating compartment 101 enters the air duct 40 through the air duct 106, and is guided to the return air inlet 104 through the air duct 40. That is, the cool air flow flowing out from the air outlet 106 flows out of the accommodating compartment 101 only, does not actually flow out of the tub 100, but flows into the air outlet duct 40 formed in the tub 100, flows along the air outlet duct 40 to the return air inlet 104, and flows out of the tub 100 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 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 air duct 10, air flows through the supply air hole 105 and the air receiving hole 202 into the top end of the air passing duct 20 in the front end plate 210 of the drawer 200, and then flows through the air 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.

In the solution of the present embodiment, the air return port 104 is disposed at the top of the rear end of the tub 100, and the air outlet duct 40 is disposed in the rear sidewall of the tub 100. So that the cold air flow in the accommodating compartment 101 can enter the air passing duct 40 from the air passing opening 106, and then flow to the air returning opening 104 through the air passing duct 40 to flow out of the barrel body 100. Thereby, can form circulation cold wind in order to refrigerate food in staving 100 to improved the parcel degree of cold wind to holding room 101, be favorable to improving the cooling homogeneity. On this basis, return air inlet 104 sets up at the rear end top of staving 100 for staving 100 can observe the butt joint condition of return air inlet 104 and refrigerator main part in the assembly process, makes the butt joint process more convenient.

In addition, the air inlet 103 and the air return 104 are both arranged at the top of the rear end of the barrel body 100, so that the positions of the air inlet 103 and the air return 104 are similar, a structure which is in butt joint with the air inlet 103 and the air return 104 is arranged on the refrigerator main body, and the butt joint of the air inlet 103 and the air return 104 with the refrigerator main body is convenient.

In addition, 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.

Moreover, 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.

Referring to fig. 4, specifically, the thickness of the air duct 40 is 5 mm or more and 30 mm or less. That is, the distance between the front wall and the rear wall of the wind passing duct 40 is 5 mm or more and 30 mm or less. For example, 5 mm, 10 mm, 15 mm, 20 mm, 25 mm, 30 mm, etc. By making the thickness of the air-passing duct 40 greater than or equal to 5 mm and less than or equal to 30 mm, the air-passing duct 40 has sufficient space for cold air to flow, which is beneficial to ensuring smooth flow of cold air after entering the air-passing duct 40.

Referring to fig. 10, the ratio of the area of the air outlet 106 to the area of the rear side wall of the accommodating chamber 101 is one fifth or more and one fifth or less. For example, it may be one fiftieth, one fortieth, one thirty, one twentieth, one tenth, one fifth, etc. Illustratively, the area of the air outlet 106 is 0.001 square meters, the area of the rear sidewall of the receiving compartment 101 is 0.05 square meters, and the ratio is one fiftieth. Alternatively, the area of the air outlet 106 is 0.02 square meters, the area of the rear side wall of the accommodating chamber 101 is 0.1 square meters, and the ratio is one fifth. Alternatively, the area of the air outlet 106 is 0.002 square meter, the area of the rear side wall of the accommodating chamber 101 is 0.04 square meter, and the ratio is one twentieth.

By making the ratio of the area of the air outlet 106 to the area of the rear side wall of the accommodating compartment 101 be greater than or equal to one fifth and less than or equal to one fifth, the cold air flow at the rear end of the accommodating compartment 101 is facilitated to smoothly flow out of the air outlet 106, and the cold air is effectively prevented from being deposited at the rear end of the accommodating compartment 101, so that the influence on the temperature uniformity in the drawer 200 caused by serious non-uniformity of the temperature in the accommodating compartment 101 is avoided.

Preferably, the ratio of the area of the air outlet 106 to the area of the rear side wall of the accommodating compartment 101 is equal to or more than one third and equal to or less than one fifth. For example, it may be one-thirty, one-twenty, one-fifteen, one-tenth, one-fifth, etc.

Referring to fig. 10, the area of the air outlet 106 is 0.001 square meter or more and 0.02 square meter or less. For example, it may be 0.001 square meter, 0.002 square meter, 0.005 square meter, 0.008 square meter, 0.01 square meter, 0.02 square meter, etc. The area of the air outlet 106 is larger than or equal to 0.001 square meter and smaller than or equal to 0.02 square meter, so that smooth outflow of cold air is guaranteed.

Preferably, the area of the air outlet 106 is 0.005 square meter or more and 0.02 square meter or less. For example, it may be 0.005 square meter, 0.006 square meter, 0.007 square meter, 0.008 square meter, 0.009 square meter, 0.01 square meter, 0.02 square meter, etc.

Referring to fig. 10, the ratio of the distance from the bottom end of the air port 106 to the bottom end of the rear side wall of the accommodating chamber 101 to the length of the rear side wall of the accommodating chamber 101 in the longitudinal direction is equal to or greater than one quarter. In particular, it may be one quarter, one third, one half, etc. Preferably one third or more.

Referring to fig. 10, the longitudinal distance from the bottom end of the air port 106 to the bottom end of the rear side wall of the accommodating chamber 101 is H, and the length in the longitudinal direction of the rear side wall of the accommodating chamber 101 is H, and H/H is one-fourth or more.

By making the ratio of the longitudinal distance from the bottom end of the air outlet 106 to the bottom end of the rear side wall of the accommodating compartment 101 to the length in the longitudinal direction of the rear side wall of the accommodating compartment 101 equal to or greater than a quarter, on the one hand, a certain distance is required to flow upwards for the cold air to reach the air outlet 106, so that the cold air can be more fully diffused in the accommodating compartment 101, and the refrigerating efficiency and the refrigerating uniformity can be improved. On the other hand, the length of the air passing duct 40 is not excessively long, thereby simplifying the structure.

Referring to fig. 1, the area of the air return opening 104 is greater than or equal to the area of the air inlet 103, so that the ventilation is smoother.

Referring to fig. 1 to 5, the ratio of the volume of the accommodating chamber 101 to the area of the air intake 103 is 5 or more and 20 or less. For example, 5, 7, 10, 15, 18, 20, etc. are possible. Illustratively, the containment compartment 101 has a volume of 0.072 cubic meters, the air intake 103 has an area of 0.0036 square meters, and the ratio is 20. Alternatively, the volume of the accommodating chamber 101 is 0.02 cubic meters, the area of the air inlet 103 is 0.004 square meters, and the ratio is 5. Alternatively, the volume of the accommodating chamber 101 is 0.06 cubic meters, the area of the air inlet 103 is 0.005 square meters, and the ratio is 12.

The ratio of the volume of the accommodating chamber 101 to the area of the air inlet 103 is greater than or equal to 5 and less than or equal to 20, so that the refrigerating efficiency of the air inlet 103 to the accommodating chamber 101 is guaranteed, and the too slow cooling rate is avoided.

Preferably, the ratio of the volume of the accommodating chamber 101 to the area of the air intake 103 is 10 or more and 15 or less. For example, 10, 12, 14, 15, etc.

Referring to fig. 5, a grid is disposed in the air outlet 106 to divide the air outlet 106 into a plurality of areas, so as to disperse the cool air and avoid the cool air from forming turbulence at the air outlet 106. At this time, the area of the air outlet 106 is the total area of the plurality of areas.

As described with reference to fig. 1, further, the rear end of the top side wall of the tub 100 is formed with an inclined section 140, and the air inlet 103 and the air return 104 are formed at the inclined section 140, and the inclined direction of the inclined section 140 is directed from the top to the bottom in the front-to-rear direction of the tub 100.

By providing the inclined section 140 in the tub 100 and forming the air inlet 103 and the air return 104 on the inclined section 140, the air inlet 103 and the air return 104 are more conveniently assembled with the refrigerator main body. Moreover, the air intake of the air inlet 103 is smoother.

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.
