[0025] See Figure 1 The utility model provides a refrigerator air duct structure 100, set up the air inlet 20 in the bottom, set up the first air outlet 30 in the position close to the top, set up the second air outlet 40 in the downside of first air outlet 30, in this way let cold air necessarily first from the top position air outlet, flow to the downside again, solved the problem of the insufficient air volume of the top of the existing refrigerator air duct structure 100.
[0026] The refrigerator air duct structure 100 is installed in the refrigerator and has a top and a bottom along the vertical direction, the refrigerator air duct structure 100 is provided with an air inlet 20, a first air outlet 30, a second air outlet 40 and a main air duct 10, the air inlet 20 is provided in the bottom of the refrigerator air duct structure 100, one end of the main air duct 10 is communicated with the air inlet 20, the other end is communicated with the first air outlet 30 and the second air outlet 40 in turn, and the first air outlet 30 is located on the side close to the top of the second air outlet 40.
[0027] In this way, cold air enters the main air duct 10 from the air inlet 20, and since the first air outlet 30 and the second air outlet 40 are communicated with the main air duct 10 in turn, the cold air necessarily reaches the first air outlet 30 first and then reaches the second air outlet 40. The first air outlet 30 is located on the side close to the top of the second air outlet 40, so the cold air will first reach the top and then flow to the bottom, thus ensuring that the wind power and the air volume at the top are sufficient and the refrigeration effect at the top is ensured.
[0028] Further, the first air outlet 30 and the second air outlet 40 are both provided on the side surface of the refrigerator air duct structure 100 in the horizontal direction. In this way, the processing of the first air outlet and the second air outlet is facilitated, and the cold air in the refrigerator storage space is more uniform.
[0029] Of course, in other embodiments, the first air outlet 30 and the second air outlet 40 can also be directly provided on the front surface of the refrigerator air duct structure 100 facing the refrigerator storage space, and are not limited to air outlets from the side surface.
[0030] The third air outlet 50 is further arranged on the refrigerator air duct structure 100, and the third air outlet 50 is communicated with the main air duct 10, and the first air outlet 30, the second air outlet 40 and the third air outlet 50 are arranged from top to bottom along the vertical direction. In this way, the cold air first flows out from the first air outlet 30, then flows out from the second air outlet 40, and finally flows out from the third air outlet 50, and the multiple air outlets make the cold air more uniform.
[0031] Preferably, the first air outlet 30, the second air outlet 40 and the third air outlet 50 are uniformly spaced, so that the cold quantity in the refrigerator storage space is more uniform, thereby improving the refrigeration effect.
[0032] It can be understood that in other embodiments, the refrigerator air duct structure 100 can also change the positional relationship of the first air outlet 30, the second air outlet 40 and the third air outlet 50 according to the different cold quantity required by each area in the refrigerator storage space.
[0033] Further, the flow area of the first air outlet 30 is smaller than that of the second air outlet 40, and the flow area of the second air outlet 40 is smaller than that of the third air outlet 50. Since the first air outlet 30 is closest to the air inlet 20 in the flow path of the cold air, the wind speed here is the largest, so the flow area is reduced accordingly, and the second air outlet 40 and the third air outlet 50 are gradually farther away in turn, so the flow area gradually increases, which can make the total air volume of the first air outlet 30, the second air outlet 40 and the third air outlet 50 more uniform, so that the cold quantity is more uniform.
[0034] Preferably, the refrigerator air duct structure 100 includes an air outlet unit, and the air outlet unit includes the first air outlet 30, the second air outlet 40 and the third air outlet 50. The refrigerator air duct structure 100 is provided with the air outlet unit on both sides in the horizontal direction. In this way, the air volume of the refrigerator air duct structure 100 on both sides is more uniform.
[0035] The main air duct 10 includes a first air duct 11 and a second air duct 12, the first air duct 11 is communicated with the air inlet 20, the second air duct 12 is communicated with the first air duct 11, and the second air duct 12 includes a first path 121 and a second path 122, the first path 121 is communicated between the second path 122 and the first air duct 11, at least part of the first path 121 is arc-shaped, and the axis of the second path 122 is arranged in parallel with the axis of the first air duct 11. In this way, the arc-shaped part of the first path 121 can guide the wind direction of the cold air flowing into the air inlet 20, and after the second path 122 and the first path 121 are arranged in parallel, the first path 121 reverses the direction of the flowing cold air and flows to the bottom again, and in the process of flowing to the bottom, the cold air flows out from each air outlet.
[0036] The first branch 31, the second branch 41 and the third branch 51 are communicated with the second path 122 respectively, and an end of the first branch 31 away from the second path 122 is communicated with the first air outlet 30, an end of the second branch 41 away from the second path 122 is communicated with the second air outlet 40, and an end of the third branch 51 away from the second path 122 is communicated with the third air outlet 50. In this way, the cold air flows to the three air outlets through the first branch 31, the second branch 41 and the third branch 51 on the second path 122, reducing the problem of cold air turbulence.
[0037] Further, along the direction away from the first air duct 11, the first branch 31, the second branch 41 and the third branch 51 are all inclined towards the bottom. In this way, the first branch 31, the second branch 41 and the third branch 51 can guide the cold air to flow downwards.
[0038] The utility model also provides a refrigerator, including the refrigerator air duct structure 100 as described above.
[0039] Compared with the prior art, the utility model discloses the air inlet 20 is arranged at the bottom of the refrigerator air duct structure 100, and the cold air enters the main air duct 10 from the air inlet 20, so the cold air must reach the first air outlet 30 first and then reach the second air outlet 40 because the first air outlet 30 and the second air outlet 40 are communicated with the main air duct 10 in turn. The first air outlet 30 is located at the side of the second air outlet 40 close to the top, so the cold air will reach the top first and then flow to the bottom, and therefore the wind power and the wind volume at the top can be ensured to be sufficient, and the refrigeration effect at the top can be ensured.
[0040] The technical features of the above-described embodiments can be combined arbitrarily, and to make the description concise, all possible combinations of the technical features in the above-described embodiments are not described, but as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope of the description.
[0041] The above-described embodiments only express several implementation manners of the utility model, the description is more specific and detailed, but it should not be understood as the limitation of the scope of the utility model patent. It should be pointed out that for ordinary skilled persons in the art, on the premise of not departing from the concept of the utility model, a number of modifications and improvements can be made, which all belong to the protection scope of the utility model.
