[0033] In order to have a further understanding of the purpose, structure, features, and functions of this application, please refer to the attached Figure 1-8 The details of the embodiments are as follows.

[0034] In response to the problem of uneven air distribution from the refrigerator air outlet, the present application provides an air supply device 1, comprising an air guide 12 and a vent 11, the air guide 12 being connected to the refrigerator inner tank 4; the vent 11 being connected to the air outlet of the air guide 12, a plurality of air guide plates 16 being arranged in the vent 11 to form three air ducts in different directions, and a baffle 17 being fixedly arranged in at least one of the air ducts, the baffle 17 being used to block part of the air outlet of the air duct. Specifically, the air guide 12 is connected to the refrigerator liner 4 to guide the cold air of the refrigerator refrigeration system into the vent 11. The vent 11 and the air guide 12 are arranged in cooperation to rectify the cold air guided by the air guide 12. The vent 11 is provided with multiple air guide plates 16 to form three air ducts in different directions. The three air ducts in different directions include a first air duct with a wind direction toward the left, a second air duct with a wind direction toward the middle, and a third air duct with a wind direction toward the right. The three air ducts in different directions can ensure that the cold air can be evenly distributed to every corner of the refrigerator. It should be noted that the present application does not impose specific restrictions on the number of air guide plates 16, that is, the first air duct, the second air duct, and the third air duct can all include multiple air guide plates 16; the baffle 17 is fixedly arranged in the air duct to block part of the air outlet of the air duct. By blocking part of the air outlet, the amount of cold air entering each area inside the refrigerator can be effectively adjusted to avoid overcooling or overheating in some areas, thereby improving the overall refrigeration effect and food preservation quality.

[0035] In one embodiment of the present application, the vent 11 includes a first vent 14 provided in conjunction with the air outlet and at least one second vent 15 extending along a first direction and connected to the first vent 14; the first direction is set to be parallel to the intersection of the liner 4 and the horizontal plane, see Figure 1 , the first direction is Figure 1 The first ventilation portion 14 is arranged in conjunction with the air outlet of the air guide 12 to ensure that the cold air flows smoothly from the air guide 12 into the ventilation opening 11. The at least one second ventilation portion 15 is configured to expand along the first direction and connect to the first ventilation portion 14 to allow the cold air to be further dispersed and expanded on the basis of the first ventilation portion 14 to cover a larger area inside the refrigerator.

[0036] Preferably, there is one second ventilation portion 15, and the air guide plate 16 in the air duct where the second ventilation portion 15 is located guides the air to the second ventilation portion 15. Specifically, the vent 11 is composed of a first ventilation portion 14 and a second ventilation portion 15 connected thereto. In the air duct where the second ventilation portion 15 is located, the air guide plate 16 is configured to guide the cold air to the second ventilation portion 15. If the second ventilation portion 15 is located to the left of the first ventilation portion 14, the air guide plate 16 in the left first air duct guides the cold air to the second ventilation portion 15; if the second ventilation portion 15 is located to the right of the first ventilation portion 14, the air guide plate 16 in the right third air duct guides the cold air to the second ventilation portion 15.

[0037] In an optional embodiment of the present application, two second ventilation parts 15 are provided, which are respectively provided on the left and right sides of the first ventilation part 14, wherein the cold air in the second ventilation part 15 located on the left side of the first ventilation part 14 is guided to the second ventilation part 15 by the wind guide plate 16 in the first air duct on the left; the cold air in the second ventilation part 15 located on the right side of the first ventilation part 14 is guided to the second ventilation part 15 by the wind guide plate 16 in the third air duct on the right.

[0038] The cold air first enters the first ventilation part 14 through the air guide 12, and then enters the second ventilation part 15 which is closely connected to the first ventilation part 14 after being rectified and guided by the air guide plate 16. Through the second ventilation part 15, the cold air is evenly distributed to every corner of the refrigerator, achieving efficient cooling effect and uniform air volume distribution.

[0039] In one embodiment, the extension lines of the air deflectors 16 in the same air duct form a first angle between each other, and the extension lines of the air deflectors 16 in different air ducts form a second angle between each other, with the first angle being smaller than the second angle. For example, any air deflector 16a in the first air duct forms a first angle with the extension line of any other air deflector 16 in the same air duct, and a second angle forms between the air deflector 16a and the extension line of any air deflector 16 in the second air duct or the third air duct, with the first angle being smaller than the second angle. That is, the air deflectors 16 in the same air duct direct the cold air to the same side to form a concentrated cold air flow, thereby enhancing the cooling effect within the air duct. Between different air ducts, a larger second angle allows for a wider cold air coverage area, ensuring a more uniform temperature throughout the refrigerator.

[0040] A plurality of air guide plates 16 are provided in the vent 11 to form air ducts in three different directions, namely, a first air duct that guides the air outlet of the vent 11 to a first direction, an intermediate air duct that guides the air outlet to a middle direction, and a second air duct that guides the air outlet to a second direction, wherein one of the first direction and the second direction is a left direction and the other is a right direction. The baffle 17 can be fixedly provided on at least one of the three air ducts in different directions. In an optional embodiment, the baffle 17 is fixedly provided on the middle air duct. That is, the baffle 17 is used to block part of the air outlet of the middle air duct, thereby adjusting the amount of cold air in the middle air duct. The present application blocks part of the air outlet by the baffle 17 to ensure that the amount of cold air in the other two air ducts is relatively sufficient, thereby achieving a more balanced air volume distribution.

[0041] Preferably, the plane where the baffle 17 is located is set to be perpendicular to the air outlet direction of the middle air duct, and the air outlet direction of the middle air duct is perpendicular to the inner tank 4, see Figure 1 , that is, the plane where the baffle 17 is located is parallel to the xz plane, and the baffle 17 blocks part of the air outlet of the middle air duct, so that the cold air from the other two air ducts can be more evenly distributed to various areas of the refrigerator, which helps the cold air to form a uniform flow inside the refrigerator.

[0042] The vent 11 includes an upper cover plate, a lower cover plate arranged opposite to the upper cover plate, and two side plates connecting the upper cover plate and the lower cover plate. The upper cover plate has a first side length along the second direction, and the lower cover plate has a second side length along the second direction. The first side length is greater than the second side length. The second direction is a direction perpendicular to the inner tank 4. For details, see Figure 3 , the second direction is the y direction in the figure, the first side length of the upper cover is greater than the second side length of the lower cover, which can capture more cold air at the vent 11 and prevent the cold air from flowing to the upper area, resulting in a decrease in cooling efficiency; in other optional embodiments, a storage box 2 is provided below the vent 11, and the second side length of the lower cover is designed to be smaller than the first side length of the upper cover, which can better avoid the storage box 2 and at the same time concentrate more cold air on the upper surface of the storage box 2 to improve the cooling efficiency.

[0043] Preferably, the air guide plate 16 is fixedly connected to the upper cover plate and the lower cover plate, and the height of the air guide plate 16 is equal to the distance between the plane where the upper cover plate is located and the plane where the lower cover plate is located, ensuring that the cold air flows along a predetermined path when passing through the vent 11, thereby improving the cooling efficiency and the uniformity of the cold air output.

[0044] A refrigerator includes the aforementioned air supply device 1, which is secured to the refrigerator liner 4 and connected to the air duct via a connecting plate 13 that fits over the vent 11. Cold air is guided to the air supply device 1 through the air duct and enters the refrigerator interior through the vent 11, thereby achieving uniform distribution and efficient circulation of the cold air within the refrigerator. It should be noted that the air supply device 1 and the refrigerator liner 4 may be secured in a removable manner or in a fully fixed manner, and this application does not impose any specific limitations thereon.

[0045] Preferably, the refrigerator further includes a storage box 2, comprising an enclosed accommodating space and a cover disposed at the opening of the accommodating space. A moisture-permeable membrane 3 is disposed on a first surface of the cover, distal from the accommodating space. The air outlet path of the vent 11 of the air supply device 1 passes through the moisture-permeable membrane 3. The air supply device 1 is positioned higher than the upper surface of the cover of the storage box 2, so that air from the vent 11 of the air supply device 1 strikes the upper surface, circulating cold air outside the storage box 2 and indirectly cooling the storage box 2, effectively maintaining stable temperature and humidity within the storage box 2 and thereby extending the shelf life of food.

[0046] In an alternative embodiment, the moisture-permeable membrane 3 is configured to be gradually tilted upward in the y-direction, allowing the cold air from the vent 11 to blow directly onto the membrane 3. Because the cold air from the vent 11 is relatively low in temperature, condensation can easily form on the cover plate. This condensation not only affects the humidity balance within the refrigerator but can also cause food in the storage compartment 2 to mold. When the cold air blows directly onto the moisture-permeable membrane 3, water vapor can pass through it, effectively reducing the formation of condensation.

[0047] In an optional embodiment, the storage box 2 is a drawer.

[0048] The present application relates to an air supply device 1 and a refrigerator, comprising an air guide 12 and a vent 11 connected to an inner tank 4 of the refrigerator, wherein the vent 11 is connected to the air outlet of the air guide 12, and a plurality of air guide plates 16 are arranged in the vent 11 to form air ducts in three different directions. A baffle 17 is fixedly arranged in at least one of the air ducts, and the baffle 17 is used to block part of the air outlet of the air duct. By arranging the baffle 17 in the air duct, the air outlet of each air duct is adjusted to achieve reasonable flow distribution and flow control of the cold air.
