[0007] According to the air volume distribution component of the embodiment of the utility model, since the air inlet is connected to the primary branch air path through the main air path, multiple secondary branch air paths are all connected to the primary branch air path.

Since each secondary branch air path is connected to multiple air outlets, the multiple air outlets are arranged at intervals along the extension direction of the secondary branch air path.

It can be understood that the main air path and the primary branch air path can disperse the airflow entering the air inlet, and the secondary branch air path can further disperse the airflow in the primary air path, thereby making the air outlet of the air volume distribution component uniformly discharge air, ensuring the uniformity of air volume distribution, which is conducive to ensuring the uniformity of the indoor temperature of the refrigeration room and improving the quality of food storage.

Since each secondary branch air path is connected to multiple air outlets, the multiple air outlets are arranged at intervals along the extension direction of the secondary branch air path.

[0037] 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.
[0038] Please refer to the following Figures 1 to 5 An air volume distribution assembly and a refrigerator according to an embodiment of the utility model are described.
[0039] like Figures 1 to 4 As shown, the air volume distribution component of the embodiment of the utility model is provided with an air inlet 1 and a plurality of air outlets 2, and a main air path 3, a primary branch air path 4 and a plurality of secondary branch air paths 5 are provided inside the air volume distribution component. The air inlet 1 is connected with the primary branch air path 4 through the main air path 3, and the plurality of secondary branch air paths 5 are all connected with the primary branch air path 4, and each secondary branch air path 5 is connected with a plurality of air outlets 2, and the plurality of air outlets 2 are arranged at intervals along the extension direction of the secondary branch air path 5.
[0040] According to the air volume distribution component of the embodiment of the utility model, since the air inlet 1 is connected to the primary branch air path 4 through the main air path 3, multiple secondary branch air paths 5 are all connected to the primary branch air path 4. Therefore, the airflow entering the air volume distribution component from the air inlet 1 can be distributed to the primary branch air path 4 through the main air path 3, and then distributed to multiple secondary branch air paths 5 by the primary branch air path 4. Since each secondary branch air path 5 is connected to multiple air outlets 2, the multiple air outlets 2 are arranged at intervals along the extension direction of the secondary branch air path 5. Therefore, the airflow distributed to each secondary branch air path 5 can flow out evenly through the corresponding air outlet 2.
[0041] It can be understood that the main air path 3 and the primary branch air path 4 can disperse the airflow entering the air inlet 1, and the secondary branch air path 5 can further disperse the airflow in the primary air path, thereby making the air outlet 2 of the air volume distribution component discharge air evenly, ensuring the uniformity of air volume distribution, which is beneficial to ensuring the uniformity of temperature in the refrigeration compartment 81 and improving the quality of food storage.
[0042] In other words, the air volume distribution assembly of the embodiment of the utility model can evenly distribute the cold air flow to various places, so that the temperature of different parts of the food is close and the fluctuation is small, which is conducive to the preservation of food and prolongs the shelf life of food. There is no phenomenon of local overcooling of large air outlets blowing directly to local parts of the food, thereby avoiding the problem of food deterioration or damage caused by uneven temperature of the food itself.
[0043] Optionally, multiple secondary branch air passages 5 are arranged at intervals along the extension direction of the primary branch air passage 4. For example, multiple secondary branch air passages 5 are arranged at equal intervals along the extension direction of the primary branch air passage 4, that is, the intervals between each two adjacent secondary branch air passages 5 are equal. Thus, the air volume in the primary branch air passage 4 can be split to ensure that the multiple secondary branch air passages 5 can evenly disperse the air volume in the primary branch air passage 4.
[0044] Optionally, there is an angle between the extension direction of the main air passage 3 and the extension direction of the primary branch air passage 4. For example, the extension direction of the main air passage 3 is substantially orthogonal to the extension direction of the primary branch air passage 4. Thus, when the airflow in the main air passage 3 is transported to the primary branch air passage 4, the flow direction of the airflow can be changed due to the angle between the extension direction of the main air passage 3 and the extension direction of the primary branch air passage 4, so as to break up the airflow, which is beneficial to the uniformity of air volume distribution.
[0045] In one example, if Figure 1 and Figure 2 As shown, the first-level branch air path 4 includes a connected first section 41, a connecting section 43 and a second section 42, and the first section 41 and the second section 42 are respectively arranged on opposite sides of the connecting section 43, one end of the main air path 3 along its extension direction is connected to the air inlet 1, and the other end of the main air path 3 along its extension direction is connected to the connecting section 43, a number of secondary branch air paths 5 are arranged at intervals along the extension direction of the first section 41, and a number of secondary branch air paths 5 are arranged at intervals along the extension direction of the second section 42.
[0046] It can be understood that the airflow entering the main air passage 3 can be dispersed to the first section 41 and the second section 42 through the connecting section 43, because a plurality of secondary branch air passages 5 are arranged at intervals along the extension direction of the first section 41, and a plurality of secondary branch air passages 5 are arranged at intervals along the extension direction of the second section 42. Thus, the primary branch air passage 4 (the first section 41 and the second section 42) can evenly disperse the air volume into each secondary branch air passage 5. In the example of the present application, the extension direction of the main air passage 3 is substantially orthogonal to the extension direction of the primary branch air passage 4, so that the airflow entering the connecting section 43 can be dispersed by impacting the side wall of the connecting section 43, and diverted into the first section 41 and the second section 42.
[0047] like Figure 2 As shown, the connecting section 43 has a cone tip 431, and the cone tip 431 extends toward the direction of the air inlet 1. The air volume distribution assembly of the embodiment of the utility model can prevent the airflow from forming turbulence at the end of the main air path 3 away from the air inlet 1 by setting the cone tip 431, so as to avoid affecting the circulation efficiency of the airflow. It can be understood that the cone tip 431 can guide and separate the airflow, so as to guide the airflow on the main air path 3 to the branch air paths (i.e., the first section 41 and the second section 42) on the left and right sides respectively.
[0048] Specifically, the lengths of the first section 41 and the second section 42 are equal, and the numbers of the secondary branch air paths 5 corresponding to the first section 41 and the second section 42 are equal, thereby ensuring the uniformity of the air volume distributed between the first section 41 and the second section 42 and reducing the temperature fluctuation in the refrigeration compartment 81.
[0049] In other examples, such as Figure 3 As shown, several secondary branch air passages 5 are arranged on one side of the width direction of the primary branch air passage 4, and several secondary branch air passages 5 are arranged on the other side of the width direction of the primary branch air passage 4. It can be understood that the secondary branch air passages 5 are arranged on both sides of the width direction of the primary branch air passage 4, 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 primary branch air passages 4 and secondary branch air passages 5 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.
[0050] Optionally, there are multiple primary branch wind paths 4, all of which are connected to the main wind path 3, and each primary branch wind path 4 corresponds to a number of secondary branch wind paths 5. It can be understood that the primary branch wind paths 4 and the secondary branch wind paths 5 can be arranged roughly in a snowflake shape, thereby further improving the uniformity of air volume distribution.
[0051] Alternatively, if Figure 3As shown, there is one primary branch air passage 4, the extension direction of which is orthogonal to the extension direction of the secondary branch air passage 5, and the extension direction of the main air passage 3 is parallel to the extension direction of the primary branch air passage 4. This makes it easy to process and manufacture the main air passage 3, the primary branch air passage 4, and the secondary branch air passage 5, and the structure in which the multiple air outlets 2 are arranged is generally in a chessboard shape, which is conducive to ensuring the uniformity of the air outlet of the air volume distribution component.
[0052] In some embodiments, in the airflow direction of the primary branch air passage 4, the total ventilation area of the air outlet 2 corresponding to the multiple secondary branch air passages 5 increases in sequence. In other words, in the airflow path of the airflow in the air volume distribution component, the total ventilation area of the air outlet 2 corresponding to the secondary branch air passage 5 near the air inlet 1 is smaller, and the total ventilation area of the air outlet 2 corresponding to the secondary branch air passage 5 far from the air inlet 1 is larger. This can solve the problem of excessive local cooling caused by excessive airflow velocity near the air inlet 1, and improve the uniformity of air volume distribution of the air volume distribution component.
[0053] Alternatively, if Figure 4 As shown, the air volume distribution assembly includes a first plate 6 and a second plate 7, the second plate 7 is arranged on one side of the first plate 6 in the thickness direction, the air inlet 1, the main air path 3, the primary branch air path 4 and the secondary branch air path 5 are formed on the first plate 6, and the air outlet 2 is formed on the second plate 7. This facilitates the processing and manufacturing of the air volume distribution assembly, and the structure is simple.
[0054] Specifically, the first plate 6 includes a main body (not shown) and a raised portion (not shown), the raised portion is connected to the main body and protrudes relative to the main body, and the main air passage 3, the primary branch air passage 4 and the secondary branch air passage 5 are all surrounded by the main body and the raised portion. Therefore, it is convenient to form the main air passage 3, the primary branch air passage 4 and the secondary branch air passage 5 on the first plate 6, with a simple structure and convenient processing and forming.
[0055] For example, the first plate 6 and the second plate 7 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.
[0056] For another example, the first plate 6 and the second plate 7 are split structures. Specifically, the first plate 6 and the second plate 7 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 7 needs to correspond to the secondary branch air path 5 on the first plate 6.
[0057] In the example of the present application, the first plate 6 is a foam plate, and the second plate 7 is a plastic plate. By designing the first plate 6 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 on the plate. Designing the second plate 7 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.
[0058] like Figure 5 As shown, a refrigerator according to another embodiment of the utility model comprises a box body 8 and an air volume distribution assembly of the utility model. The box body 8 has a refrigeration compartment 81, which may be one or more refrigeration compartments 81, and an air inlet 811 is provided on the inner wall of the refrigeration compartment 81. The air volume distribution assembly is assembled on the box body 8, and the air inlet 1 of the air volume distribution assembly is connected to the air inlet 811, and the air volume distribution assembly is used to supply air to the refrigeration compartment 81.
[0059] According to the refrigerator of the embodiment of the utility model, since the air inlet 1 is connected to the primary branch air path 4 through the main air path 3, multiple secondary branch air paths 5 are all connected to the primary branch air path 4. Therefore, the airflow entering the air volume distribution component from the air inlet 1 can be distributed to the primary branch air path 4 through the main air path 3, and then distributed to multiple secondary branch air paths 5 by the primary branch air path 4. Since each secondary branch air path 5 is connected to multiple air outlets 2, multiple air outlets 2 are arranged at intervals along the extension direction of the secondary branch air path 5. Therefore, the airflow distributed to each secondary branch air path 5 can flow out evenly through the corresponding air outlet 2. It can be understood that the main air path 3 and the primary branch air path 4 can disperse the airflow entering the air inlet 1, and the secondary branch air path 5 can further disperse the airflow in the primary air path, thereby making the air outlet 2 of the air volume distribution component uniformly discharge air, ensuring the uniformity of air volume distribution, which is conducive to ensuring the uniformity of temperature in the refrigeration compartment 81 and improving the quality of food storage.
[0060] Specifically, the refrigerator also includes a drawer, which encloses a storage cavity 9. The drawer is pullable in the refrigeration compartment 81, and the air volume distribution component is arranged directly above the storage cavity 9, so that the air volume distribution component can evenly distribute the cold air into the storage cavity 9.
[0061] Optionally, the air volume distribution assembly is fixedly mounted on the box body 8. It is understandable that the air volume distribution assembly and the box body 8 are not removable, thereby improving the reliability of the installation of the air volume distribution assembly and the box body 8.
[0062] In other examples, the air volume distribution assembly is detachably mounted on the housing 8, so that the user or maintenance personnel can remove the air volume distribution assembly from the housing 8 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 housing 8 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-fit structure, a guide rail structure, and a plug-in structure.
