[0024] See also Figures 1 to 5 As shown, according to an embodiment of the present application, a noise reduction structure includes a noise reduction member 1, a noise reduction hole 11 is provided on the noise reduction member 1, the noise reduction member 1 is arranged in an air duct, and the noise reduction member 1 is arranged at a non-zero angle with the flow direction of the fluid in the air duct, so that the fluid in the air duct can flow through the noise reduction hole 11. By providing the noise reduction member 1, the cavity noise generated in the air duct can be reflected and consumed in the noise reduction hole 11 on the noise reduction member 1, thereby reducing the cavity noise and improving the user experience.

[0025] Furthermore, the noise reduction member 1 is in the shape of a flat plate.

[0026] There are multiple noise reduction holes 11, and the multiple noise reduction holes 11 are evenly arranged on the noise reduction component 1. By arranging multiple noise reduction holes 11 and making the multiple noise reduction holes 11 uniform, a good noise reduction effect can be ensured.

[0027] Furthermore, the diameter of the noise reduction hole 11 is 1 to 100 mm, and the distance between the center of the noise reduction hole 11 and the center of the adjacent noise reduction hole 11 is 1 to 100 mm.

[0028] Specifically, in this embodiment, the diameter of the noise reduction hole 11 is 3 mm, and the distance between the center of the noise reduction hole 11 and the center of the adjacent noise reduction hole 11 is 30 mm.

[0029] Furthermore, the center line of the noise reduction hole 11 is perpendicular to the flat plate structure formed by the noise reduction component 1 .

[0030] The noise reduction structure further includes a support member 2, and the noise reduction member 1 is arranged on the air duct wall of the air duct through the support member 2. The support member 2 is provided to ensure stable installation of the noise reduction member 1.

[0031] Furthermore, the support member 2 is substantially a right-angled triangle, wherein one right-angled side is connected to the duct wall of the duct, wherein the hypotenuse is connected to the noise reduction member 1, and the other right-angled side is horizontally arranged.

[0032] Furthermore, the support member 2 extends along the flow direction of the air duct.

[0033] Specifically, in this embodiment, the support member 2 extends vertically.

[0034] The outer wall of the support member 2 is streamlined along the flow direction of the air duct. When the airflow flows from top to bottom or from bottom to top in the flow channel, the streamlined support plate can be used to straighten the airflow, reduce the probability of vortex generation inside the air conditioner, and solve the problem that the airflow in the cavity inside the air conditioner is easy to form vortex or turbulence.

[0035] Furthermore, the support member 2 is a long strip plate, and the two side walls of the support member 2 with a larger area are streamlined. Figure 4 It is roughly spindle-shaped in a top view.

[0036] Furthermore, the left and right side walls of the support member 2 are streamlined.

[0037] As other embodiments, the support member 2 may also be in a diamond shape, a flat plate shape, or a porous shape.

[0038] There are multiple support members 2, and the multiple support members 2 are evenly arranged on the noise reduction member 1. By arranging multiple support members 2, the stable installation of the noise reduction member 1 is further guaranteed.

[0039] Furthermore, the plurality of support members 2 are arranged in the horizontal direction, that is, the plurality of support members 2 are evenly arranged on the noise reduction member 1 in the horizontal direction.

[0040] Specifically, in this embodiment, the number of the support members 2 is 3, wherein one support member 2 is arranged at the left end of the noise reduction member 1, one support member 2 is arranged at the right end of the noise reduction member 1, and one support member 2 is arranged in the middle of the noise reduction member 1.

[0041] In another aspect of the present embodiment, an air conditioner indoor unit is provided, comprising the noise reduction structure as described above.

[0042] The indoor unit of the air conditioner comprises a heat exchanger 3 , and the noise reduction element 1 is arranged in parallel with the heat exchanger 3 .

[0043] Furthermore, when the air conditioner indoor unit turns on the downward air outlet mode, the noise reduction component 1 is arranged on the downstream side of the heat exchanger 3 along the flow direction.

[0044] Specifically, in this embodiment, the noise reduction component 1 is disposed below the heat exchanger 3 , and a gap is left between the noise reduction component 1 and the heat exchanger 3 .

[0045] Furthermore, the noise reduction element 1 is arranged in parallel with the heat exchanger 3. The hypotenuse of the right triangle formed by the support frame is parallel to the heat exchanger 3.

[0046] Furthermore, the noise reduction component 1 and the heat exchanger 3 are both arranged obliquely.

[0047] The air conditioner indoor unit comprises a first cross flow blade 4 and a second cross flow blade 5 , which are arranged in the air duct, and the noise reduction element 1 is arranged in the air duct between the first cross flow blade 4 and the second cross flow blade 5 .

[0049] The air conditioner indoor unit includes a panel 6 . When the noise reduction structure includes a support member 2 , the support member 2 is disposed on the panel 6 .

[0050] Furthermore, the support plate is connected to the panel 6 by screws, and forms a part of the air duct together with the bottom shell and the like.

[0051] When the indoor unit of the air conditioner is in the down-flow mode, the wind flows through the evaporator for heat exchange and then enters the noise reduction component 1. At this time, the cavity noise and the duct noise are reflected and consumed by the noise reduction holes 11 and the panel 6, thereby reducing the cavity noise. After the wind flows through the noise reduction component 1, it passes through the support plate. At this time, the wind can flow downward along the side wall of the support plate. The support plate can comb the wind to avoid the generation of eddy currents, thereby avoiding the occurrence of duct noise or cold concentration.

[0052] In another aspect of the present embodiment, an air conditioner is provided, comprising the noise reduction structure as described above or the air conditioner indoor unit as described above.

[0053] A noise reduction structure, an air conditioner indoor unit and an air conditioner provided in the embodiments of the present invention can reduce cavity noise and improve the user experience.

Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application. The above are only preferred implementations of the present application.
