[0032] In the related art, the inlet flow area of the air outlet duct of the air conditioner is smaller than the outlet flow area, that is, the inlet flow area of the air outlet duct is smaller than the outlet flow area, resulting in the problem of insufficient air outlet flow on both sides of the outlet of the air outlet duct. This leads to the problem that air flow reflux is likely to occur at the outlet of the air outlet duct, and further leads to the generation of surging sound, that is, noise, at the outlet of the air outlet duct.

[0033] The present disclosure improves the problem of insufficient air outlet flow existing at the outlet of the air outlet duct by providing a protrusion at the outlet of the air outlet duct, thereby reducing the risk of air flow reflux occurring at the outlet of the air outlet duct, and further reducing the noise generated by the air outlet duct, that is, reducing the noise during the operation of the air conditioner.

[0034] The embodiments of the present disclosure will be described in detail below. The examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present disclosure and should not be construed as a limitation of the present disclosure.

[0035] As Figures 1 to 4 shown, the air outlet duct 10 of the embodiment of the present disclosure is an air outlet duct 10 with an upward air outlet. The air outlet duct 10 includes a duct housing 1 and a protrusion 2. The duct housing 1 has a duct 11 extending in the front-rear direction and an outlet 12 communicating with the duct 11. The outlet 12 is provided on the front side of the duct 11. The protrusion 2 is provided at the outlet 12 and is connected to the duct housing 1. Among them, the up-down direction is as Figures 1 to 4 shown, and the front-rear direction is as Figure 3 and Figure 4 shown.

[0036] For the air outlet duct 10 of the embodiment of the present disclosure, by providing a protrusion 2 at the outlet 12 of the duct 11, the cross-sectional flow area of the outlet 12 can be reduced, thereby improving the problem of insufficient air outlet flow existing at the outlet 12, reducing the risk of air flow reflux occurring at the outlet 12, and further reducing the noise generated by the air outlet duct 10, that is, reducing the noise during the operation of the air conditioner 100 having the air outlet duct 11.

[0037] In some embodiments, as Figure 1 and Figure 3 shown, the protrusion 2 is provided at the upper part of the duct 11.

[0038] Experimental studies have shown that the upper part of the outlet 12 of the air duct 11 is most prone to problems of insufficient air outlet flow, and it is easy to generate noise due to air flow backflow.

[0039] By arranging the protrusion 2 on the upper part of the air duct 11, the problem of insufficient air outlet flow at the outlet 12 can be more effectively improved, thereby more effectively reducing the noise of the air outlet duct 10.

[0040] In some embodiments, as Figure 1 shown, the protrusion 2 is arranged on both sides of the air duct 11 in the left-right direction.

[0041] Experimental studies have shown that the two sides of the air duct 11 in the left-right direction are most prone to problems of insufficient air outlet flow, and it is easy to generate noise due to air flow backflow.

[0042] By arranging the protrusion 2 on both sides of the air duct 11 in the left-right direction, the problem of insufficient air outlet flow at the outlet 12 can be more effectively improved, thereby more effectively reducing the noise of the air outlet duct 10.

[0043] Optionally, as Figure 1 shown, the protrusions 2 arranged on both sides of the air duct 11 are symmetrically arranged in the left-right direction.

[0044] By arranging the protrusions 2 arranged on both sides of the air duct 11 symmetrically in the left-right direction, the outlet 12 of the air duct 11 is symmetrically arranged in the left-right direction, so that the air outlet flow of the air duct 11 is more uniform in the left-right direction, which is beneficial to improving the user experience of the air conditioner 100 having the air outlet duct 10.

[0045] In some embodiments, as Figure 3 shown, the protrusion 2 has a first end 211 and a second end 221 arranged oppositely in the front-back direction, and the first end 211 is arranged on the front side of the second end 221. The distance between the first end 211 and the outlet 12 is greater than or equal to 0 and less than or equal to 70 mm, and / or the distance between the second end 221 and the outlet 12 is greater than or equal to 10 mm and less than or equal to 120 mm. In other words, as Figure 3 shown, the distance between the first end 211 and the outlet 12 is n, the distance between the second end 221 and the outlet 12 is m, m > n, 0 ≤ n ≤ 70 mm, 10 mm ≤ m ≤ 120 mm.

[0046] For example, as Figure 3 shown, the front end opening of the air duct 11 is the outlet 12. The front end of the protrusion 2 is the first end, and the distance between the front end of the protrusion 2 and the outlet 12 is greater than or equal to 0 and less than or equal to 70 mm; the rear end of the protrusion 2 is the second end, and the distance between the rear end of the protrusion 2 and the outlet 12 is greater than or equal to 10 mm and less than or equal to 120 mm.

[0047] By making the distance between the first end 211 and the outlet 12 greater than or equal to 0 and less than or equal to 70 mm, and the distance between the second end 221 and the outlet 12 greater than or equal to 10 mm and less than or equal to 120 mm, the problem of insufficient air flow at the outlet 12 can be effectively improved, thereby more effectively reducing the noise generated by the air outlet duct 10.

[0048] Optionally, the height of the protrusion 2 is greater than or equal to 2 mm and less than or equal to 30 mm. In other words, as Figure 4 shown, the height of the protrusion 2 is t, and 2 mm ≤ t ≤ 30 mm.

[0049] It can be understood that the greater the height of the protrusion 2, the smaller the flow area of the outlet 12, and the greater the impact on the air volume flowing out of the outlet 12, which is not conducive to increasing the air volume of the air outlet duct 10; the smaller the height of the protrusion 2, the larger the flow area of the outlet 12, which is not conducive to improving the problem of insufficient air flow at the outlet 12, and noise will still be generated due to air flow reflux.

[0050] By setting the height of the protrusion 2 to be greater than or equal to 2 mm and less than or equal to 30 mm, the flow area of the outlet 12 will not be reduced too much. While improving the problem of insufficient air flow at the outlet 12, it can also ensure the air volume flowing out of the outlet 12, so that the air conditioner 100 with the air outlet duct 10 has a large air volume while having low noise.

[0051] In some embodiments, as Figure 3 and Figure 4 shown, the duct housing 1 includes a mounting wall 13, and the protrusion 2 is connected to the mounting wall 13. The protrusion 2 has a first side surface 21 and a second side surface 22 arranged oppositely in the front-rear direction, and the first side surface 21 is arranged on the front side of the second side surface 22. The first side surface 21 is arranged to gradually incline away from the mounting wall 13 in the front-to-back direction, and / or the second side surface 22 is arranged to gradually incline towards the mounting wall 13 in the front-to-back direction.

[0052] Among them, the first side surface 21 is arranged to gradually incline away from the mounting wall 13 in the front-to-back direction, and / or the second side surface 22 is arranged to gradually incline towards the mounting wall 13 in the front-to-back direction, which can be understood as: the first side surface 21 is arranged to gradually incline away from the mounting wall 13 in the front-to-back direction, and the second side surface 22 is arranged to gradually incline towards the mounting wall 13 in the front-to-back direction; or, the first side surface 21 is arranged to gradually incline away from the mounting wall 13 in the front-to-back direction; or, the second side surface 22 is arranged to gradually incline towards the mounting wall 13 in the front-to-back direction.

[0053] For example, as Figure 3 and Figure 4As shown, the front side of the protrusion 2 is the first side 21, and the rear side of the protrusion 2 is the second side 22. The first side 21 is arranged to gradually slope downward in the front-to-back direction, and the second side 22 is arranged to gradually slope upward in the front-to-back direction. During specific use, the air flow flows in the direction from the rear to the front.

[0054] By arranging the first side 21 to gradually slope away from the mounting wall 13 in the front-to-back direction, and / or arranging the second side 22 to gradually slope towards the mounting wall 13 in the front-to-back direction, at least one of the first side 21 and the second side 22 guides the outgoing air flow, reducing the flow resistance of the outgoing air flow, thereby reducing the air volume loss of the air outlet duct 10, which is beneficial to increasing the air volume of the air outlet of the air outlet duct 10.

[0055] Optionally, the angle between the second side 22 and the mounting wall 13 is greater than 0° and less than 70°. In other words, the angle between the second side 22 and the mounting wall 13 is α, where 0° < α < 70°.

[0056] By setting the angle between the second side 22 and the mounting wall 13 to be greater than 0° and less than 70°, the flow resistance of the outgoing air flow can be effectively reduced, the air volume loss of the air outlet duct 10 can be reduced, and the air volume of the air outlet of the air outlet duct 10 can be increased.

[0057] In some embodiments, as Figure 4 shown, the protrusion 2 further includes a connecting surface 23 facing the air duct 11, and the connecting surface 23 is arranged between the first side 21 and the second side 22. The connecting surface 23 is arranged to gradually slope away from the mounting wall 13 in the front-to-back direction.

[0058] By arranging the connecting surface 23 to gradually slope away from the mounting wall 13 in the front-to-back direction, the connecting surface 23 guides the outgoing air flow, reducing the flow resistance of the outgoing air flow, thereby reducing the air volume loss of the air outlet duct 10, which is beneficial to increasing the air volume of the air outlet of the air outlet duct 10.

[0059] Optionally, the angle between the connecting surface 23 and the mounting wall 13 is greater than or equal to 0° and less than 40°. In other words, as Figure 4 shown, the angle between the connecting surface 23 and the mounting wall 13 is β, where 0° ≤ β < 40°.

[0060] By setting the angle between the connecting surface 23 and the mounting wall 13 to be greater than or equal to 0° and less than 40°, the flow resistance of the outgoing air flow can be effectively reduced, the air volume loss of the air outlet duct 10 can be reduced, and the air volume of the air outlet of the air outlet duct 10 can be increased.

[0061] In some embodiments, as Figure 3 and Figure 4 shown, the protrusion 2 is a hollow structure.

[0062] For example, the protrusion 2 is provided at the upper part of the air duct 11, and a part of the air duct housing 1 protrudes downward to form the protrusion 2.

[0063] By making the protrusion 2 a hollow structure, the weight of the air outlet duct 10 can be reduced, and the material cost of the air outlet duct 10 can be saved.

[0064] Optionally, as Figure 3 and Figure 4 shown, the air outlet duct 10 includes a reinforcing rib 3, and the reinforcing rib 3 is provided on the side of the protrusion 2 facing away from the air duct 11 and is connected to the protrusion 2.

[0065] For example, as Figure 3 and Figure 4 shown, the reinforcing rib 3 is provided on the upper side of the protrusion 2, and the lower end of the reinforcing rib 3 is connected to the protrusion 2.

[0066] By providing the reinforcing rib 3, the strength of the protrusion 2 can be improved, thereby enhancing the reliability of the air outlet duct 10.

[0067] Optionally, the reinforcing rib 3 and the protrusion 2 are integrally formed.

[0068] For example, the reinforcing rib 3 and the protrusion 2 are integrally injection-molded.

[0069] By integrally forming the reinforcing rib 3 and the protrusion 2, the number of components of the air outlet duct 10 can be reduced, and the cost of the air outlet duct 10 can be lowered.

[0070] Of course, in some other embodiments, the reinforcing rib 3 and the protrusion 2 can also be connected by snap-fits, screws, etc.

[0071] Optionally, the protrusion 2 and the air duct housing 1 are integrally formed.

[0072] For example, the protrusion 2 and the air duct housing 1 are integrally injection-molded.

[0073] By integrally forming the protrusion 2 and the air duct housing 1, the number of components of the air outlet duct 10 can be reduced, and the cost of the air outlet duct 10 can be lowered.

[0074] Of course, in some other embodiments, the protrusion 2 and the air duct housing 1 can also be connected by snap-fits, screws, etc.

[0075] As Figure 1 and Figure 2 shown, the air conditioner 100 according to the embodiment of the present disclosure includes the air outlet duct 10 described in any one of the above embodiments.

[0076] Among them, the air conditioner 100 includes a housing 20, and the air duct housing 1 is connected to the housing 20.

[0077] The air conditioner 100 according to an embodiment of the present disclosure improves abnormal noise caused by air flow reflux due to insufficient air flow at the outlet 12 by providing a protrusion 2 at the outlet 12 of the air duct 11, thereby improving the abnormal sound quality of the air conditioner 100 and enhancing the user experience of the air conditioner 100.

[0078] Although the embodiments of the present disclosure have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present disclosure. Any changes, modifications, substitutions, and variations made by those of ordinary skill in the art to the above embodiments are within the protection scope of the present disclosure.
