FIG. 1 is a three-dimensional schematic diagram of an embodiment of the wind deflector of the present invention, and FIG. 2 is a schematic plan view of an embodiment of the wind deflector of the present invention. As shown in Figs. 1 and 2, in one or more embodiments, the wind deflector body 1 has a substantially rectangular plate structure. Therefore, the wind deflector body 1 has a first short side 1a, a second short side 1b, a first long side 1c, and a second long side 1d. The first short side 1a and the second short side 1b are opposed to each other, and the first long side 1c and the second long side 1d are opposed to each other. The size of the long side and the short side and the ratio between the long side and the short side can be determined according to actual applications. Alternatively, in other embodiments, the wind deflector body 1 may also adopt other shapes, such as a substantially square plate structure.

As shown in FIG. 1 and FIG. 2, in one or more embodiments, eight swing blades 2 are formed on one side surface of the wind deflector body 1. In alternative embodiments, the number of swing leaves can be less or more according to actual needs, and it is best to use an even number of swing leaves. For example, the number of swing leaves can be appropriately increased according to the applied indoor area. These swing vanes 2 are integrally formed with the wind deflector body 1, for example, by injection molding or other integral molding methods, and extend outward perpendicular to the surface of the wind deflector body 1. Therefore, these swing blades 2 also become mutually spaced reinforcing ribs that can increase the strength of the wind deflector. As shown in Fig. 1, in one or more embodiments, each swing blade 2 has an arc-shaped or streamlined outer edge in order to reduce wind resistance.

As shown in FIG. 1, in one or more embodiments, the eight swing blades 2 are symmetrically arranged on both sides of the center line C of one side surface of the wind deflector body 1. The center line C is perpendicular to the first long side 1c and the second long side 1d and extends through the center of the surface of the wind deflector body 1. When the air deflector is installed in the air outlet of the air conditioner, the side surface of the air deflector body 1 will become the inner side surface of the air deflector, facing the inside of the air conditioner. As shown in FIG. 1, on the left side of the center line C along the direction extending from the center line C to the left side of the surface of the wind deflector body 1, a first left swing leaf 2a1, a second left swing leaf 2a2, and a second The three left swing blades 2a3 and the fourth left swing blade 2a4, therefore, the first left swing blade 2a1 is closest to the center line 2a1. Similarly, a first right swing leaf 2b1, a second right swing leaf 2b2, and a third right swing leaf 2b1, a second right swing leaf 2b2, and a third right swing leaf are sequentially arranged on the right side of the center line C along a direction extending from the right side of the surface of the center line C of the wind guide body 1.

The swing blade 2b3 is symmetrical with respect to the center line C; and the fourth left swing blade 2a4 and the fourth right swing blade 2b4 are symmetrical with the center line C.

Continuing to refer to FIG. 1, each swing blade forms an angle with the center line C, for example, the first left swing blade 2a1 forms an included angle α with the center line C, and the first right swing blade 2b1 forms an included angle β with the center line. Since the first left swing blade 2a1 and the first right swing blade 2b1 are symmetrical with respect to the center line C, the angle β and the angle α are the same. The eight swing blades 2 are therefore arranged in the shape of four "eights" on the surface of the air deflector body 1. As shown in FIG. 1, in one or more embodiments, along the direction extending from the center line C to the left side of the surface of the wind deflector body 1, the angle formed by each swing blade and the center line C is Increasing successively, that is, the included angle formed by the second left swing blade 2a2 and the center line C is greater than the included angle α, and the included angle formed by the third left swing blade 2a3 and the center line C is greater than that formed by the second left swing blade 2a2 and the center line C The included angle formed by the fourth left swing blade 2a4 and the center line C is greater than the included angle formed by the third left swing blade 2a3 and the center line C. Similarly, along the direction extending from the center line C to the right side of the surface of the wind guide body 1, the angle formed by each swing blade and the center line C also increases sequentially, that is, the second right swing blade 2b2 and The included angle formed by the center line C is greater than the included angle β. The included angle formed by the third right swing blade 2b3 and the center line C is greater than the included angle formed by the second right swing blade 2b2 and the center line C. The fourth right swing blade 2b4 and the center The angle formed by the line C is greater than the angle formed by the third right swing blade 2b3 and the center line C. Since the angle formed by the swing blades on either side of the center line C and the center line C gradually increases, a certain angle is also formed between adjacent swing blades on both sides of the center line C, so that the air supply area can be increased. Optionally, on both sides of the center line C, the angle formed by each swing blade and the center line C is increased by the same value (in other words, increased by a fixed value), that is, the angle formed between adjacent swing blades is the same . Alternatively, the angle formed by each swing blade and the center line C may also be the same or increase by a different value.
