[0040] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0041] Please refer to the following Figures 1 to 8 An air volume distribution assembly and a refrigerator according to an embodiment of the utility model are described.

[0042] like Figures 1 to 4 As shown, the air volume distribution assembly of the embodiment of the utility model is provided with an air inlet 1 and multiple groups of air outlets 2. A main air path 3 and multiple branch air paths 4 are provided in the air volume distribution assembly, and the air inlet 1 is connected with the multiple branch air paths 4 via the main air path 3. Along the extension direction of the main air path 3, at least multiple branch air paths 4 are arranged in sequence, and multiple air outlets 2 are arranged in sequence along the extension direction of the main air path 3 to form multiple groups of air outlets 2 corresponding to each branch air path 4 one by one.

[0043] In the direction from one end of the main air passage 3 adjacent to the air inlet 1 to one end of the main air passage 3 away from the air inlet 1 , the ventilation areas of the plurality of air outlet groups 2 tend to increase.

[0044] It should be noted that the ventilation area of ​​each group of air outlets 2 is, that is, the sum of the opening areas of the air outlets 2 corresponding to each branch air passage 4 .

[0045] It is understandable that each group of air outlets 2 may include only one air outlet 2 , or each group of air outlets 2 may include a plurality of air outlets 2 .

[0046] Specifically, in a solution where each group of air outlets 2 has only one air outlet 2 (i.e., each branch air path 4 corresponds to one air outlet 2), the air outlet 2 may be in a long strip shape and consistent with the extension direction of the branch air path 4. In a solution where each group of air outlets 2 includes multiple air outlets 2 (i.e., each branch air path 4 corresponds to multiple air outlets 2), the multiple air outlets 2 may be arranged at intervals along the extension direction of the branch air path 4.

[0047] According to the air volume distribution component of the embodiment of the utility model, since the air inlet 1 is connected to the plurality of branch air paths 4 respectively via the main air path 3, the airflow entering the air volume distribution component from the air inlet 1 can be evenly distributed to each branch air path 4 through the main air path 3. Since the plurality of air outlets 2 are arranged in sequence along the extension direction of the main air path 3 to form a plurality of groups of air outlets 2 corresponding to each branch air path 4, the airflow distributed to each branch air path 4 can flow out evenly through the corresponding air outlets 2. Since the ventilation area of ​​the plurality of groups of air outlets 2 tends to increase in the direction from one end of the main air path 3 adjacent to the air inlet 1 to the end of the main air path 3 away from the air inlet 1, the problem of excessive local cooling caused by excessive airflow velocity at the position adjacent to the air inlet 1 can be solved, the uniformity of air volume distribution of the air volume distribution component is improved, which is conducive to ensuring the uniformity of the indoor temperature of the refrigeration room and improving the quality of food storage.

[0048] It can be understood that the main air path 3 can disperse the airflow entering the air inlet 1, and the branch air path 4 can further disperse the airflow in the main air path 3, thereby allowing the air outlet 2 of the air volume distribution component to discharge air evenly, ensuring the uniformity of air volume distribution, which is beneficial to ensuring the uniformity of the indoor temperature of the refrigeration room and improving the quality of food storage.

[0049] like Figure 2 and Figure 3As shown, the air inlet 1 is arranged near the rear side of the air volume distribution component, and the main air path 3 extends in the front-to-back direction. The airflow entering the main air path 3 will flow in the direction from back to front. In the direction from back to front, the total ventilation area of ​​the air outlet 2 corresponding to the multiple branch air paths 4 increases successively. In other words, the total ventilation area of ​​the air outlet 2 corresponding to the branch air path 4 near the position of the air inlet 1 is smaller, and the total ventilation area of ​​the air outlet 2 corresponding to the branch air path 4 far away from the position of the air inlet 1 is larger. In this way, the problem of excessive local cooling caused by excessive air flow velocity near the position of the air inlet 1 can be solved, and the uniformity of air volume distribution of the air volume distribution component can be improved.

[0050] Optionally, in the direction from one end of the branch air passage 4 adjacent to the main air passage 3 to one end of the branch air passage 4 away from the main air passage 3, each branch air passage 4 is inclined toward the side away from the air inlet 1. Figure 4 As shown, the air inlet 1 is arranged adjacent to the rear side of the air volume distribution component, and the main air path 3 gradually extends toward the front side of the air volume distribution component. In the direction from one end of the branch air path 4 adjacent to the main air path 3 to the end of the branch air path 4 away from the main air path 3, the branch air path 4 gradually extends obliquely toward the front side of the air volume distribution component. On the one hand, the resistance of the air flow from the main air path 3 to the branch air path 4 can be reduced, reducing wind loss. On the other hand, the wind discharged from the branch air path 4 can flow toward the front side of the air volume distribution component, thereby improving the uniformity of the air volume distribution of the air volume distribution component and reducing the fluctuation of the indoor temperature of the refrigeration room.

[0051] Optionally, in the direction from one end of the main air path 3 adjacent to the air inlet 1 to the end of the main air path 3 away from the air inlet 1, each group of air outlets 2 is gradually arranged close to the main air path 3. In other words, on the branch air path 4 close to the air inlet 1 (i.e., the branch air path 4 adjacent to the rear side of the air volume distribution component), the air outlet 2 is farther away from the main air path 3, and on the branch air path 4 far away from the air inlet 1 (i.e., the branch air path 4 far away from the rear side of the air volume distribution component), the air outlet 2 is closer to the main air path 3.

[0052] It is understandable that, since the return air outlet for refrigeration preparation is arranged at the rear side of the air volume distribution component, when the air outlet 2 on the rear branch air path 4 is close to the main air path 3, the cold air discharged from the air outlet 2 on the rear branch air path 4 is easy to return directly to the return air outlet, thereby reducing the circulation efficiency of the cold air. The air volume distribution component of the embodiment of the utility model can increase the circulation path of the cold air flowing out of the air outlet 2 of the rear branch air path 4 by adopting the above arrangement of each group of air outlets 2, so as to avoid the problem of ineffective air supply.

[0053] In the example of the present application, each group of air outlets 2 includes a plurality of air outlet holes 21 that are independent of each other and spaced apart. The air outlet holes 21 of each group of air outlets 2 are arranged in an array and arranged along the extension direction of the branch air path 4. In other words, each group of air outlets 2 includes a plurality of rows of air outlet holes 21, and the plurality of rows of air outlet holes 21 are spaced apart along the width direction of the branch air path 4, and each row of air outlet holes 21 includes a plurality of air outlet holes 21, and the plurality of air outlet holes 21 are spaced apart along the extension direction of the branch air path 4, thereby improving the uniformity of the air outlet 2.

[0054] The air outlet 21 is at least one of a circular hole, an elliptical hole and a polygonal hole. It is understandable that the air outlet 2 can be any combination of a circular hole, an elliptical hole and a polygonal hole. The actual shape of the air outlet 21 can be selectively designed according to the structure of the air volume distribution component and its arrangement position, and this application does not limit this.

[0055] Alternatively, if Figure 2 and Figure 3 As shown, in the direction from one end of the main air path 3 adjacent to the air inlet 1 to the end of the main air path 3 away from the air inlet 1, the aperture of the air outlet 21 tends to increase. It can be understood that the aperture of the air outlet 21 on the branch air path 4 adjacent to the air inlet 1 area is smaller, and the aperture of the air outlet 21 on the branch air path 4 away from the air inlet 1 area is larger. Since the wind speed in the area adjacent to the air inlet 1 is relatively high, by reducing the aperture of the air outlet 21 on the branch air path 4 adjacent to the air inlet 1 area, the air volume allocated to the branch air path 4 adjacent to the air inlet 1 area can be reduced, so that the air volume allocated to the branch air path 4 adjacent to the air inlet 1 area and the branch air path 4 away from the air inlet 1 area are roughly equal, thereby improving the uniformity of air volume distribution of the air volume distribution component.

[0056] Alternatively, if Figure 2 and Figure 3 As shown, in the direction from one end of the branch wind path 4 adjacent to the main wind path 3 to the end of the branch wind path 4 away from the main wind path 3, the distance between two adjacent air outlets 21 tends to decrease. It can be understood that in the flow direction of the airflow in the branch wind path 4, the distance between two adjacent air outlets 21 gradually decreases. Since the wind speed of the air outlets 21 in the area adjacent to the main wind path 3 is relatively high, in the flow direction of the airflow in the branch wind path 4, the air outlets are arranged more and more densely, which can increase the air volume allocated to the air outlets 21 away from the main wind path 3, so that the air volume allocated to the air outlets 21 in the area adjacent to the main wind path 3 and the air outlets 21 away from the main wind path 3 are roughly equal, thereby improving the uniformity of air volume distribution of the air volume distribution component.

[0057] For example, Figure 2 and Figure 3As shown, in the direction from one end of the main air path 3 adjacent to the air inlet 1 to the end of the main air path 3 away from the air inlet 1, the arrangement lengths of the air outlets 2 corresponding to the plurality of branch air paths 4 gradually increase, and the air volumes allocated to the branch air paths 4 in the area adjacent to the air inlet 1 and the branch air paths 4 away from the air inlet 1 can be made roughly equal, thereby improving the uniformity of the air volume distribution of the air volume distribution component.

[0058] In some embodiments, the axial direction of the air outlet holes 21 adjacent to the edge of the air volume distribution component is arranged parallel to the thickness direction of the air volume distribution component. It can be understood that the drawer of the refrigeration compartment has a storage cavity, and the air outlet direction of the air outlet holes adjacent to the edge of the air volume distribution component is parallel to the up and down direction of the storage cavity, thereby preventing the air outlet 2 adjacent to the edge of the air volume distribution component from blowing cold air to the outside of the storage cavity, thereby preventing the phenomenon of ineffective air supply.

[0059] Furthermore, the axial direction of the air outlet holes 21 away from the edge of the air volume distribution assembly is inclined in a direction away from the air inlet 1. It can be understood that the air outlet direction of the air outlet holes 21 away from the edge of the storage cavity gradually shifts toward the front side of the storage cavity, thereby ensuring that more cold air returns to the back side of the storage cavity after participating in heat exchange from the front side of the storage cavity, thereby improving the effect of cold volume circulation of the storage cavity.

[0060] It should be noted that there may be one or more main air ducts 3, and this application does not limit this.

[0061] Take the scheme with multiple main air passages 3 as an example. Multiple main air passages 3 are connected to the air inlet 1, each main air passage 3 corresponds to a plurality of branch air passages 4, and the plurality of branch air passages 4 are arranged at intervals along the extension direction of the corresponding main air passage 3. It can be understood that the airflow entering the air inlet 1 can be dispersed into each main air passage 3, and since each main air passage 3 corresponds to a plurality of branch air passages 4, the airflow can be further dispersed, thereby improving the uniformity of the air output of the air volume distribution component.

[0062] In one example, if Figure 2 and Figure 4 As shown, the main air path 3 includes a first main path 31 and a second main path 32 which are arranged at intervals. The first main path 31 and the second main path 32 extend in the same direction. In other words, the first main path 31 and the second main path 32 are arranged side by side and extend in the same direction. A number of branch air paths 4 are connected to the first main path 31 and are arranged on one side of the width direction of the main air path 3, and a number of branch air paths 4 are connected to the second main path 32 and are arranged on the other side of the width direction of the main air path 3, so that the airflow distributed by the air volume distribution component can be gradually dispersed from the center to the edge. It can be understood that the arrangement of the above-mentioned main air path 3 and branch air paths 4 is generally distributed in a dendrite-like (fishbone-like) manner to improve the uniformity of the air volume distribution of the air volume distribution component.

[0063] Alternatively, if Figures 5 to 7 As shown, the air volume distribution assembly includes a first plate 5 and a second plate 6, the second plate 6 is arranged on one side of the first plate 5 in the thickness direction, the air inlet 1, the main air path 3 and the branch air path 4 are formed on the first plate 5, and the air outlet 2 is formed on the second plate 6. This facilitates the processing and manufacturing of the air volume distribution assembly, and the structure is simple.

[0064] Specifically, Figure 6 As shown, the first plate 5 includes a main body 51 and a raised portion 52, the raised portion 52 is connected to the main body 51 and protrudes relative to the main body 51, and the main air passage 3 and the branch air passage 4 are surrounded by the main body 51 and the raised portion 52. Therefore, it is convenient to form the main air passage 3 and the branch air passage 4 on the first plate 5, the structure is simple, and the processing and forming is convenient.

[0065] For example, the first plate 5 and the second plate 6 are an integrated structure. Specifically, the air volume distribution assembly is an integrally injected plastic plate to reduce the number of components to be assembled.

[0066] For example, Figures 5 to 7 As shown, the first plate 5 and the second plate 6 are split structures. Specifically, the first plate 5 and the second plate 6 can be connected by various assembly methods such as bonding, screwing or clamping. When assembling the air volume distribution assembly, the air outlet 2 on the second plate 6 needs to correspond to the branch air path 4 on the first plate 5.

[0067] In the example of this application, Figures 5 to 7 As shown, the first plate 5 is a foam plate, and the second plate 6 is a plastic plate. By designing the first plate 5 as a foam plate, the heat preservation effect of the air volume distribution assembly can be improved, and it is convenient to process the main air path 3 and the branch air path 4 on the plate. Designing the second plate 6 as a plastic plate can ensure the structural strength of the air volume distribution assembly and reduce the probability of damage to the air volume distribution assembly due to bumps.

[0068] like Figure 8 As shown, a refrigerator according to another embodiment of the present invention comprises a box body 7 and an air volume distribution assembly of the present invention. The box body 7 has a refrigeration compartment 71, which may be one or more refrigeration compartments 71, and an air inlet 711 is provided on the inner wall of the refrigeration compartment 71. The air volume distribution assembly is assembled on the box body 7, and the air inlet 1 of the air volume distribution assembly is connected to the air inlet 711, and the air volume distribution assembly is used to supply air to the refrigeration compartment 71.

[0069] According to another embodiment of the refrigerator of the utility model, since the air inlet 1 is connected to the plurality of branch air paths 4 respectively via the main air path 3, the airflow entering the air volume distribution component from the air inlet 1 can be evenly distributed to each branch air path 4 through the main air path 3. Since the plurality of air outlets 2 are arranged in sequence along the extension direction of the main air path 3 to form a plurality of groups of air outlets 2 corresponding to each branch air path 4, the airflow distributed to each branch air path 4 can flow out evenly through the corresponding air outlets 2. Since the ventilation area of ​​the plurality of groups of air outlets 2 increases in the direction from one end of the main air path 3 adjacent to the air inlet 1 to the end of the main air path 3 away from the air inlet 1, the problem of excessive local cooling caused by excessive air flow velocity at the position adjacent to the air inlet 1 can be solved, the uniformity of air volume distribution of the air volume distribution component can be improved, and it is beneficial to ensure the uniformity of the indoor temperature of the refrigeration room and improve the quality of food storage.

[0070] Specifically, the refrigerator further includes a drawer, which encloses a storage cavity. The drawer is installed in the refrigeration compartment 71 in a pull-out manner. The air volume distribution component is arranged directly above the storage cavity, so that the air volume distribution component can evenly distribute the cold air into the storage cavity.

[0071] Optionally, the air volume distribution assembly is fixedly mounted on the box body 7. It is understandable that the air volume distribution assembly and the box body 7 are not removable, thereby improving the reliability of the installation of the air volume distribution assembly and the box body 7.

[0072] In other examples, such as Figure 8 As shown, the air volume distribution assembly can be detachably mounted on the box body 7, so that the user or maintenance personnel can remove the air volume distribution assembly from the box body 7, which is convenient for subsequent maintenance and replacement. In the above embodiment, in order to facilitate the installation and removal of the air volume distribution assembly, the air volume distribution assembly is provided with a mounting portion (not shown), and the box body 7 is provided with a matching portion (not shown) matching the mounting portion. The mounting portion and the matching portion can be connected in a variety of matching ways such as a snap-on structure, a guide rail structure, and a plug-in structure.
