[0032] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0033] Reference below Figure 1-Figure 9 A refrigerator 100 according to an embodiment of the present invention is described.

[0034] like Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, the refrigerator 100 according to the embodiment of the utility model includes: an inner tank 10, a foaming layer and an air supply duct 20.

[0035] Specifically, a storage cavity 11 is defined in the inner tank 10, and a plurality of cold air outlets 12 are arranged at intervals up and down on the inner wall of the storage cavity 11. For example, there may be two, three or four cold air outlets 12. A foaming layer is provided on the outer wall of the inner tank 10, and an air supply pipe 20 is provided in the foaming layer. An air supply duct 21 is defined in the air supply pipe 20. The air supply pipe 20 has a plurality of air outlets 22 connected to the air supply duct 21. The plurality of air outlets 22 correspond to and are connected to the plurality of cold air outlets 12 one by one. The refrigerator 100 is configured so that the air volume of the plurality of cold air outlets 12 gradually decreases from top to bottom.

[0036] When the refrigerator 100 is in operation, cold air is blown into the storage cavity 11 from the air supply duct 21 in the air supply pipe 20 through the multiple air outlets 22 and the multiple cold air outlets 12 , and the cold air cools the storage cavity 11 , thereby realizing the refrigeration function of the refrigerator 100 .

[0037] Among them, blowing out cold air from a plurality of cold air outlets 12 spaced apart from each other in the upper and lower parts can improve the uniformity of the cold air distribution in the storage cavity 11 , thereby improving the uniformity of the temperature distribution in the storage cavity 11 .

[0038] It can be understood that the temperature of the cold air is lower than the temperature in the storage cavity 11, and the cold air blown out from the cold air outlet 12 will flow downward under the action of gravity. In this way, the cold air blown out from the upper cold air outlet 12 will be cooled by the lower space during the downward flow.

[0039] In the present embodiment, the air volume of the multiple cold air outlets 12 is gradually reduced from top to bottom, so that the cold air blown out of the upper cold air outlet 12 flows downward under the action of gravity, and can cool down the area below the storage cavity 11 together with the cold air blown out of the lower cold air outlet 12. Since the air volume of the cold air outlet 12 at the top is greater than that of the cold air outlet 12 at the bottom, in the areas corresponding to the upper cold air outlet 12 and the lower cold air outlet 12, the difference in heat exchange efficiency between the cold air and the storage cavity 11 is small, thereby further improving the uniformity of temperature distribution in the storage cavity 11.

[0040] The air supply pipe 20 is arranged in the foam layer, and the space of the foam layer can be reasonably utilized so that the air supply pipe 20 does not occupy the space in the inner container 10. In this way, the volume of the storage cavity 11 in the inner container 10 can be larger, and the refrigerator 100 can store more items. The foam layer reduces the heat exchange between the storage cavity 11 and the external environment. At the same time, when the cold air passes through the air supply duct 21, the foam layer can reduce the heat exchange between the cold air and the external environment, thereby improving the efficiency of the refrigerator 100 and reducing the energy consumption of the refrigerator 100.

[0041] The foam layer wraps the air supply duct 20, and the foam layer can seal the air supply duct 20 on the outside of the air supply duct 20. On the one hand, it can reduce the sealing materials required to seal the air supply duct 20 and reduce the production cost. On the other hand, it can improve the sealing reliability of the air supply duct 20 and reduce the probability of air leakage in the air supply duct 20 causing cold air to generate frost in the refrigerator 100.

[0042] During the assembly process, the air supply pipe 20 is wrapped in the foam layer, which can reduce the steps required for fixing the air supply pipe 20, thereby simplifying the assembly process and improving the assembly efficiency.

[0043] It is understandable that during the foaming process of the foaming layer, the foaming material will squeeze the air supply pipe 20. In this embodiment, by arranging a support member in the air supply duct 21, the support member can provide support for the air supply pipe 20, thereby improving the anti-extrusion ability of the air supply pipe 20 and reducing the probability of the air supply pipe 20 being deformed or even crushed by the extrusion of the foaming layer. Therefore, the yield rate in the production process can be improved.

[0044] According to the refrigerator 100 of the embodiment of the utility model, by setting the air supply duct 20 in the foaming layer, the proportion of the storage volume of the refrigerator 100 in the refrigerator 100 can be increased, and by gradually reducing the air volume of the multiple cold air outlets 12 from top to bottom, the uniformity of the temperature distribution in the storage cavity 11 can be improved.

[0045] In some embodiments of the utility model, the outlet area of ​​the plurality of air outlets 22 gradually decreases from top to bottom. It can be understood that the flow speed of the cold air in the air supply duct 21 is constant, and when the outlet area of ​​the air outlet 22 changes, the air volume will also change proportionally, thereby achieving a gradual decrease in the air volume of the plurality of cold air outlets 12 from top to bottom. At the same time, the structure of the air outlet 22 and the cold air outlet 12 is relatively simple, which can reduce the production difficulty and production cost during the production process, and make it easier to calculate the relevant parameters during the product design process, thereby reducing the difficulty of product design.

[0046] In some embodiments of the present invention, Figure 6-Figure 8 As shown, an air guide grille 221 is provided at the air outlet 22, and the air guide grille 221 is fixedly connected to the air supply pipe 20. By providing the air guide grille 221, on the one hand, the air guide grille 221 can make the air outlet of the air outlet 22 more uniform, thereby further improving the uniformity of the temperature distribution in the storage cavity 11, and on the other hand, the user can adjust the air outlet direction through the air guide grille 221, thereby achieving directional cooling in the storage cavity 11. Preferably, the air guide grille 221 is bolted to the air supply pipe 20.

[0047] In some embodiments of the present invention, Figure 4 and Figure 5As shown, the edge of the cold air outlet 12 is formed with a groove 13 that is concave toward the air outlet 22, and the edge of the air guide grille 221 away from the air supply pipe 20 is formed with a folded edge that is folded outward, and the folded edge is arranged in the groove 13. During the assembly process, the air guide grille 221 passes through the cold air outlet 12 and is fixedly connected to the air supply pipe 20. The folded edge cooperates with the groove 13 to position and limit the air guide grille 221. In this way, the air guide grille 221 can be quickly placed in place, and the operator can fix the air guide grille 221 more easily when fixing the air guide grille 221, thereby reducing the difficulty of assembly and improving the assembly efficiency. In addition, when the foam material expands excessively and squeezes into the cold air outlet 12, the groove 13 can increase the capacity of the foam material and reduce the probability of the foam material entering the storage cavity 11, thereby further improving the yield rate in the production process.

[0048] In some embodiments of the present invention, Fig. 9 As shown, the air supply duct 20 includes a first air duct plate 24 and a second air duct plate 25 , and both side edges of the first air duct plate 24 in the width direction are respectively connected to both side edges of the second air duct plate 25 in the width direction, and cooperate to define an air supply duct 21 .

[0049] During the production process, the first air duct plate 24 and the second air duct plate 25 can be produced separately. In this way, the molds for producing the first air duct plate 24 and the second air duct plate 25 are relatively simple, which can reduce the production difficulty and production cost. During the assembly process, the assembly sequence of the first air duct plate 24 and the second air duct plate 25 can be adjusted according to the assembly space requirements, thereby meeting more assembly needs and reducing the assembly difficulty.

[0050] During product design, parameters such as the size of the first air duct plate 24 and the second air duct plate 25, the shape of the first air duct plate 24 and the second air duct plate 25, or the relative angle between the first air duct plate 24 and the second air duct plate 25 can be adjusted to meet more product design needs.

[0051] In some embodiments of the present invention, Figure 3 and Figure 6 As shown, the refrigerator 100 further includes: a sealing member 30, which extends in a ring shape along the periphery of the air outlet 22, one end of the sealing member 30 is sealedly connected to the periphery of the air outlet 22, and the other end of the sealing member 30 is sealedly connected to the periphery of the cold air outlet 12. By providing the sealing member 30, when the cold air enters the cold air outlet 12 from the air outlet 22, it can be prevented from flowing out from the gap between the air outlet 22 and the cold air outlet 12, thereby ensuring the air supply efficiency.

[0052] In some embodiments of the present invention, Figure 7 and Figure 8As shown, the seal 30 includes a connecting portion 31 and a sealing skirt 32, wherein the connecting portion 31 is annular and connected to the edge of the air outlet 22, the inner end of the sealing skirt 32 is connected to the connecting portion 31, and the outer end of the sealing skirt 32 is in sealing contact with the edge of the cold air outlet 12. Thus, the seal 30 can seal the gap between the air outlet 22 and the cold air outlet 12, wherein the sealing skirt 32 is connected to the outer side of the connecting portion 31, and when the sealing skirt 32 contacts the edge of the cold air outlet 12, the contact area between the seal 30 and the edge of the cold air outlet 12 can be increased, thereby improving the sealing reliability of the sealing skirt 32 at the edge of the cold air outlet 12.

[0053] During product design, parameters such as the size of the connection portion 31 and the sealing skirt 32 , the shape of the connection portion 31 and the sealing skirt 32 , or the relative angle between the connection portion 31 and the sealing skirt 32 may be adjusted to meet more product design requirements.

[0054] In some embodiments of the present invention, Figure 7 and Figure 8 As shown, in the direction from the cold air outlet 12 to the air outlet 22, the sealing skirt 32 extends along an arc convex toward the air outlet 22. During the foaming process of the foaming material, the foaming material may squeeze the sealing skirt 32. By extending the sealing skirt 32 along the arc convex toward the air outlet 22, on the one hand, the strength of the sealing skirt 32 can be improved, and the anti-extrusion ability of the sealing skirt 32 can be improved. On the other hand, when the foaming material squeezes the sealing skirt 32, the sealing skirt 32 can be deformed in the direction away from the air outlet 22, absorbing a part of the squeezing of the foaming material on the sealing skirt 32, thereby reducing the probability of sealing failure between the sealing skirt 32 and the edge of the cold air outlet 12.

[0055] In some embodiments of the present invention, Figure 8 As shown, the thickness of the sealing skirt 32 gradually decreases from the inside to the outside of the sealing member 30. In this way, the outer edge of the sealing skirt 32 can be more easily deformed, and when the sealing skirt 32 is sealed and connected with the edge of the cold air outlet 12, the contact area between the sealing skirt 32 and the edge of the cold air outlet 12 can be increased, thereby improving the sealing reliability of the sealing skirt 32 and the edge of the cold air outlet 12.

[0056] In some embodiments of the present invention, Fig. 9 As shown, the seal 30 is integrally formed with the first air duct plate 24, thereby, on the one hand, reducing the difficulty of connecting the seal 30 with the air supply pipe 20 and improving production efficiency, and on the other hand, improving the reliability of the seal between the seal 30 and the air supply pipe 20.

[0057] In some embodiments of the present invention, Figure 3 and Figure 6As shown, the air supply pipe 20 also has an air inlet 23 connected to the air supply duct 21, a connecting plate 231 is formed at the edge of the air inlet 23, a connecting boss 14 is formed on the inner liner 10, and the connecting plate 231 is connected to the connecting boss 14. The air inlet 23 is connected to the compressor, and the cold air compressed by the compressor enters the air supply pipe 20 from the air inlet hole. By providing the connecting plate 231, the contact area between the air supply pipe 20 and the inner liner 10 can be increased. During the foaming process of the foaming layer, the foaming material can resist the connecting plate 231 after foaming, thereby improving the reliability of the connection between the air inlet 23 of the air supply pipe 20 and the inner liner 10, and the connecting plate 231 has a large area, which can facilitate the operator to position during the operation. By setting the connecting boss 14, a mounting position can be provided for the connecting plate 231. The protruding connecting boss 14, on the one hand, has less obstruction during operation, which can facilitate the operator to operate. On the other hand, after the foam material squeezes the connecting plate 231, it is easier to make the connecting plate 231 fit with the connecting boss 14.

[0058] In some embodiments of the present invention, Figure 3 and Figure 6 As shown, a positioning protrusion 141 is formed on the connection boss 14, and a positioning groove 2311 is formed on the connection plate 231, and the positioning protrusion 141 is matched with the positioning groove 2311. Therefore, during the assembly process, the positioning protrusion 141 cooperates with the positioning groove 2311, which makes it easier for the operator to put the connection plate 231 in place. During the foaming process of the foaming layer, the positioning protrusion 141 cooperates with the positioning groove 2311 to limit the connection plate 231, thereby reducing the probability that the foaming material squeezes the connection plate 231 and causes the connection plate 231 to slide off the connection boss 14.

[0059] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, there are multiple storage cavities 11, for example, there may be two, three or four storage cavities 11, and there are multiple air supply ducts 20, and the air supply ducts 20 correspond one-to-one to the storage cavities 11. Therefore, during use by the user, different items can be placed in different storage cavities 11 according to use needs, and the temperature in each storage cavity 11 can be adjusted separately, thereby improving the user experience.
