And the airflow is greatly disturbed by the air deflector after passing through the air deflector, and the noise performance of the unit is obviously deteriorated. In addition, during refrigeration, especially under a working condition of small flow, airflow is easy to flow and separate on the surface of the air deflector when passing through the air deflector, so that the surface of the air deflector, especially the airflow near the air deflector far away from one end of the air outlet, is low in speed and is easy to generate condensation.
In order to solve the problems in the prior art, the present embodiment provides an air deflector 100, where the air deflector 100 is applied to an air conditioner and is used for guiding and controlling an air flow at an air outlet of the air conditioner.

The airfoil is of a plate-shaped structure with a certain curvature, so that the airfoil wind deflector in the embodiment has a certain curvature. As shown in fig. 1, the airfoil-shaped air deflector in the present embodiment includes a first end 10 and a second end 20, where the first end 10 is an end of the air outlet of the air conditioner facing the inside of the air outlet when the air outlet performs an air outlet operation. In this embodiment, the inner side of the air outlet refers to a side of the air conditioner where a condenser, a fan blade, and other components are disposed. The second end 20 is the end of the air outlet of the air conditioner which faces the outer side of the air outlet of the air conditioner when the air outlet of the air conditioner works. In this embodiment, the outer side of the air outlet is far away from the inside of the air conditioner. In this embodiment, the area of the cross section of the first end 10 is larger than that of the cross section of the second end 20, and the area of the cross section of the first end 10 is gradually reduced to the area of the cross section of the second end 20. Therefore, after the airflow at the air outlet of the air conditioner passes through the first end 10 of the wing-shaped air deflector, the airflow can be attached to the upper surface 30 (shown in figure 2) and the lower surface 40 (shown in figure 2) of the wing-shaped air deflector to flow out due to the gradual change of the sectional dimension, the air volume loss is reduced, and the air outlet flow can be buffered due to the curvature of the wing-shaped air deflector, so that the noise is reduced, the flow separation generated on the surface of the air flow when the air flow passes through the wing-shaped air deflector is improved, and the condensation risk is reduced.
In one implementation, as shown in fig. 2, the airfoil wind deflector in the present embodiment includes an upper surface 30 and a lower surface 40; one end of the lower surface 40 is in arc transition connection with the first end 10, and the other end of the lower surface 40 is in arc transition connection with the second end 20; one end of the upper surface 30 is connected with the first end 10 through an arc transition, and the other end of the upper surface 30 is connected with the second end 20 through an inclined plane 50.

In addition, an inclined plane 50 is disposed between the upper surface 30 and the second end 20 in the present embodiment, the inclined plane 50 is also in arc transition connection with the upper surface 30 and the second end 20, and as can be seen from fig. 2 and 3, the inclined plane 50 in the present embodiment is inclined from the upper surface 30 to the second end 20, and the airfoil wind deflector itself has a certain curvature (as shown in fig. 2), and by disposing the inclined plane 50, the airfoil wind deflector can guide the wind flow, so that the wind flow can be output horizontally, the separation loss is reduced, and the noise is reduced. In an implementation manner, in this embodiment, an included angle between the inclined plane 50 and the second end 20 is 60 ° to 150 °, and the included angle between the inclined plane 50 and the second end 20 is set in a reasonable range, which is beneficial to ensuring smooth air outlet of the outlet airflow.

Specifically, referring to fig. 2, the cross section of the airfoil wind deflector in the present embodiment is arc-shaped, and the cross-sectional dimension is different from the first end 10 to the second end 20. The cross-sectional area of the aerofoil wind deflector shown in figure 2 increases from the first end 10 and then decreases until it decreases to the cross-sectional area of the second end 20. In this embodiment, the maximum thickness of the airfoil air deflector is a, the distance from the intersection point of the upper surface 30 of the airfoil air deflector and the inclined surface 50 to the lower surface 40 of the airfoil air deflector is B, and in order to ensure that the structural strength and the air outlet at the inclined surface 50 are smoother, the value of B/a is controlled to be greater than or equal to 0.4 and less than or equal to 0.95 in this embodiment, that is, B/a is greater than or equal to 0.4 and less than or equal to 0.95, so that it can be ensured that the thickness at the intersection point between the inclined surface 50 and the upper surface 30 and the maximum thickness of the airfoil air deflector do not differ too much, thereby ensuring the structural strength. In an embodiment, the thickness of the second end 20 of the airfoil wind deflector is C, and the value of C/B is greater than or equal to 0.4 and less than or equal to 0.95, that is, C/B is greater than or equal to 0.4 and less than or equal to 0.95, and similarly, in this embodiment, the difference between the thickness of the second end 20 and the thickness of the intersection point between the inclined plane 50 and the upper surface 30 is controlled not to be too large, so that the structural strength of the second end 20 is ensured, and the second end 20 is prevented from being broken due to collision. In specific implementation, the thickness C of the second end 20 in this embodiment may be set to be equal to or greater than 0.5mm, so as to meet the strength requirement of the second end 20.

In one embodiment, in the present embodiment, the position corresponding to the maximum camber F of the airfoil wind deflector is E, and the position corresponding to the maximum camber is a distance from the first end 10 of the airfoil wind deflector to the maximum camber F along the chord direction (i.e. the direction from the first end 10 to the second end 20). In this embodiment, the value of E/D is controlled to be greater than or equal to 0.2 and less than or equal to 0.7, that is, E/D is greater than or equal to 0.2 and less than or equal to 0.7, so that the position of the maximum camber F of the airfoil air deflector can be ensured to be located at a reasonable position of the whole chord length D, so as to buffer the outlet airflow and ensure smooth outlet airflow. In one implementation, the maximum thickness a of the airfoil wind deflector corresponds to a position G, and the maximum thickness corresponds to a distance from the first end 10 of the airfoil wind deflector to the maximum thickness a along the chord direction (i.e. the direction from the first end 10 to the second end 20). The value of G/D in this embodiment is greater than or equal to 0.1 and less than or equal to 0.45, i.e., 0.1. ltoreq. G/D.ltoreq.0.45. When the air conditioner is used for air outlet, the first end 10 of the airfoil-shaped air deflector faces the inner side of the air outlet, that is, the first end 10 is close to the air outlet, so that the wind power and the air volume suffered by the first end 10 are maximum. In order to ensure the overall structural strength of the airfoil air deflector, the embodiment controls the position corresponding to the maximum thickness of the airfoil air deflector to be close to the first end 10, so that the structural strength of the airfoil air deflector can be effectively increased to bear the outlet airflow.
It can be seen that, in the present embodiment, the air deflector 100 in the air conditioner is set to be the wing-shaped structure, because there is a gradual change in the sectional dimension of the wing-shaped structure, and the area of the cross section of the first end facing the inner side of the air outlet of the air conditioner is greater than the area of the cross section of the second end facing the outer side of the air outlet of the air conditioner, so that the air quantity loss can be reduced while the air deflector flow guiding effect is ensured, the flow state of the air flow when the air flow passes through the air deflector is improved, the noise performance is ensured, the flow separation of the surface of the air flow when the air flow passes through. As shown in fig. 4, fig. 4 is a graph of CFD (Computational fluid dynamics) simulation results. When the wing-shaped air deflector provided by the embodiment is adopted, the air output is improved by 1.3% compared with that of the traditional air deflector; and the flow separation of the upper surface 30 of the wing-shaped air deflector and the second end 20 is obviously improved, which is beneficial to reducing the condensation risk and preventing the pneumatic noise from deteriorating.
Based on the above embodiment, the present invention further provides an air conditioner, a partial structure of an air outlet of the air conditioner is shown in fig. 1, and the air conditioner in this embodiment includes the air deflector in the above embodiment. The air deflector in the embodiment is arranged in the wing-shaped structure, and the cross section size of the wing-shaped structure is gradually changed, and the area of the cross section of the air deflector is gradually reduced from the first end to the second end, so that the air deflector flow guiding effect is ensured, the air quantity loss is reduced, the flowing state of air flow flowing through the air deflector is improved, the noise performance is ensured, the surface of the air flow generates flow separation when the air flow passes through the air deflector under the working condition of low flow is improved, and the condensation risk is reduced.
