The air duct is like the "highway" of air, which connects different chambers inside the refrigerator and the fan, and is mainly made of plastic to ensure smooth inner wall to reduce wind resistance. The air outlet and air inlet are the passage ports of air inlet and outlet, and their shape, size and layout affect the ventilation effect.

[0003] When the fan rotates, negative pressure is formed at the air inlet, external air is sucked in, and then the air is transported along the air duct to the areas that need refrigeration or preservation, and is discharged through the air outlet, achieving circulating ventilation to ensure uniform temperature and remove odor, and creating a stable environment for food preservation.

[0004] The air outlet layout of part of the ventilation assembly of refrigerator is not scientific, and is often concentrated on one side or several local areas. This makes the initial blowing direction of cold air and hot air relatively fixed, and the air volume of the area close to the air outlet is obviously larger, while the air volume of the corner and partition away from the air outlet is small, causing uneven temperature distribution in the refrigerator. For example, in a large-capacity side-by-side refrigerator, the edge storage compartment of the bottom or top layer often has a large temperature difference due to uneven air guide.

[0017] Fig. 1 FIG. 1 is a structural schematic view of a ventilation assembly of a refrigerator in an embodiment of the present application;

[0018] Fig. 2Another angle structure diagram of the ventilation assembly of the refrigerator in the embodiment of the utility model is shown. DETAILED DESCRIPTION

[0019] The utility model will be explained in further detail below in combination with the drawings and specific embodiments.

[0020] Please see Figs. 1-2 The utility model discloses a ventilation assembly of refrigerator, and the ventilation assembly is assembled in the air duct of refrigerator, and the ventilation assembly comprises a plate body 11.

[0021] The bottom of the plate body 11 is provided with a mounting plate 12, the mounting plate 12 is used for connecting the air duct of the refrigerator, and the plate body 11 is arranged along the vertical direction.

[0022] The first air guide cavity 21, the second air guide cavity 22 and the third air guide cavity 23 are arranged on the plate body 11, the plate body 11 and the first air guide cavity 21, the second air guide cavity 22 and the third air guide cavity 23 are integrally injection molded, and the first air guide cavity 21, the second air guide cavity 22 and the third air guide cavity 23 are arranged in the form of recess on the plate body 11.

[0023] The first air guide cavity 21 is communicated with the second air guide cavity 22, the first air guide cavity 21 is circular, and the second air guide cavity 22 is connected to the two sides of the first air guide cavity 21 and is arranged along the horizontal direction.

[0024] After the air in the air duct of the refrigerator enters the ventilation assembly, the air is first gathered in the first air guide cavity 21, and the regular circular structure of the first air guide cavity 21 helps to stabilize the airflow and avoid the airflow from being scattered disorderly just after entering, thereby laying a foundation for subsequent orderly air supply.

[0025] A plurality of first air outlets 31 are arranged on the side wall of the first air guide cavity 21.

[0026] A plurality of first air outlets 31 are arranged on the side wall of the first air guide cavity 21, and a purification filter screen 311 is arranged correspondingly, so as to purify the output air. When the air in the refrigerator circulates, impurities such as odors and microorganisms are mixed, and the filter screen can intercept the pollutants, so that the air delivered to the storage space is cleaner, and the freshness of the food is protected.

[0027] The plurality of first air outlets 31 are arranged on the side wall of the first air guide cavity 21, so that the air is preliminarily and uniformly distributed. Compared with a single caliber or a single side air outlet, the ring-shaped layout allows the air to blow out from multiple angles and directions, which avoids excessive concentration of air volume at a certain point in the initial stage, so that the subsequent air can be more evenly delivered to the second air guide cavity 22 connected thereto, thereby starting the first step of uniform air supply.

[0028] Due to the first air outlet 31 is distributed around, the purification filter screen 311 covers the area increases accordingly, air and filter screen more fully. More air can be filtered at the same time, reduce the purification dead angle, improve the filtering efficiency of dust, bacteria and other impurities, create a better air environment for the refrigerator, reduce the risk of food pollution, prolong the preservation time, optimize the preservation performance of the refrigerator as a whole.

[0029] The first air guide cavity 21 is a key part of connecting the upstream air duct and the subsequent second air guide cavity 22, and its structure and air outlet design ensure smooth transition of airflow. The stable output air flows smoothly into the second air guide cavity 22, reducing turbulence, helping the whole ventilation assembly to run efficiently and stably, and avoiding wind loss and uneven air supply caused by poor air duct connection.

[0030] The second air guide cavity 22 is provided with a plurality of second air outlets 32, and the second air outlets 32 are located on both sides of the first air guide cavity 21, and the purification filter screen 311 is arranged at the position corresponding to the first air outlet 31.

[0031] The second air guide cavity 22 is connected on both sides of the circular first air guide cavity 21 and extends in the horizontal direction, the main purpose is to receive the airflow from the first air guide cavity 21 and expand it in the horizontal dimension. After the air in the refrigerator air duct is preliminarily distributed by the first air guide cavity 21, it needs to be spread wider to cover a larger transverse space inside the refrigerator, and the second air guide cavity 22 provides a channel to avoid airflow concentration in the central area.

[0032] The second air outlet 32 is located on the second air guide cavity 22 on both sides of the first air guide cavity 21, and the purification filter screen 311 is arranged at the position corresponding to the first air outlet 31. Because the purification filter screen 311 will produce a certain air resistance, part of the airflow may be blocked, and the second air guide cavity 22 and the second air outlet 32 can guide this part of the blocked airflow to the two sides, ensuring the smoothness of the overall air supply, and allowing the purified air to enter the refrigerator from more angles.

[0033] The second air guide cavity 22 extends in the horizontal direction, and cooperates with the plurality of second air outlets 32, so that the air can be more evenly distributed to the left and right spaces of the refrigerator after flowing out of the first air guide cavity 21. Compared with the design without such transverse air guide structure, it can effectively fill the situation of insufficient air volume on both sides, reduce the temperature difference and air speed difference in the horizontal direction of the refrigerator, and make the food in each area be in a more stable temperature and humidity environment.

[0034] The clean air filtered by the purification filter screen 311 is not only blown out from the first air outlet 31 directly above, but also delivered to both sides in a larger range with the help of the second air guide cavity 22 and the second air outlet 32. This makes the purified air more quickly and comprehensively fill the refrigerator interior, so that the areas far from the filter screen can also obtain clean air flow in time, improve the overall air quality in the refrigerator, inhibit the growth of odors and microorganisms, and prolong the preservation period of food materials.

[0035] The third air guide cavity 23 is located below the second air guide cavity 22 and is arranged in the horizontal direction. A plurality of third air outlets 33 are arranged on the third air guide cavity 23 in the horizontal direction. The number of third air outlets 33 is greater than the number of second air outlets 32.

[0036] The third air guide cavity 23 is located below the second air guide cavity 22 and is arranged in the horizontal direction. The purpose is to focus on solving the air supply problem of the lower space in the refrigerator. The conventional ventilation assembly often has the problem of insufficient air volume in the lower layer, which leads to high temperature and poor preservation effect in the lower layer of the refrigerator. The third air guide cavity 23 can direct the air to the lower area to ensure the balance of air volume in the upper and lower layers.

[0037] A plurality of third air outlets 33 are arranged on the third air guide cavity 23 in the horizontal direction, which aims to make the air spread more evenly in the vertical and longitudinal direction of the refrigerator. After the air flow flows out from the upper first and second air guide cavities 22, it is further penetrated into every corner of the lower layer of the refrigerator with the help of the third air guide cavity 23 and the third air outlet 33, perfecting the overall air supply system.

[0038] Because the number of third air outlets 33 is greater than the number of second air outlets 32, more air can be delivered to the lower layer of the refrigerator. This effectively avoids the problem of excessive temperature difference between the upper and lower layers. Whether the food materials in the upper shelf or the lower drawer of the refrigerator can enjoy uniform and stable air flow and maintain a relatively consistent temperature environment to provide ideal preservation conditions for different food materials.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some technical features. These modifications or substitutions do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
