In addition, the terms "first", "second", "third" are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0038] The embodiments of the utility model will be described below in combination with Figures 1-3 The utility model discloses a parking air conditioner outdoor unit fan.

[0039] As Figure 1 shown, the utility model embodiment provides a parking air conditioner outdoor unit fan, including motor 1 and fan blade structure 2, wherein motor 1 is used to provide power, is responsible for driving fan blade structure 2 and rotates. Fan blade structure 2 is connected with motor 1, and fan blade structure 2 rotates under the drive of motor 1, thereby generating wind flow. Fan blade structure 2 has a plurality of drain holes 3, and the drain hole 3 can quickly remove the moisture accumulated on the fan blade surface, to prevent the influence of moisture on the fan performance. The windward surface of each drain hole 3 on the side away from motor 1 is provided with a wind baffle 4, and the wind baffle 4 can avoid the wind of the drain hole and reduce the wind noise when the fan rotates.

[0040] As Figure 2 and Figure 3 shown, in a feasible embodiment of the utility model, the wind baffle 4 shields part of the area of the circumference of the drain hole 3.

[0041] In the above embodiments, the wind blocking rib 4 blocks part of the area of the circumference of the drainage hole 3, and a water guide groove or drainage structure can be formed. When the fan rotates at a high speed, the wind blocking rib 4 can provide better support, reduce deformation and vibration of the fan blade, and improve stability and durability of the fan. In addition, by blocking part of the area of the circumference of the drainage hole 3 with the wind blocking rib 4, the effect of reducing wind noise can be achieved, and the material cost can be reduced.

[0042] As shown in Figure 3 In a feasible embodiment of the utility model, the drainage hole 3 is a circular hole, the drainage hole 3 is divided into a windward surface and a leeward surface by the first plane, the included angle between one side of the wind blocking rib 4 and the first plane is α, and 45 degrees < α < 135 degrees. The included angle between the other side of the wind blocking rib 4 and the first plane is β, and 45 degrees < β < 135 degrees.

[0043] In the above embodiments, the drainage hole 3 is provided in a circular hole shape, and the circular hole shape itself has uniform drainage performance. The specific angle of the wind blocking rib 4 can enhance the connection strength with the fan blade, reduce vibration and deformation under the action of wind force, and thus improve the stability and durability of the entire structure.

[0044] The design of the α and β angles and the reasonable included angle setting can reduce the direct impact of the wind flow on the wind blocking rib, further reduce the noise level, and also make the wind blocking rib 4 and the fan blade more coordinated and beautiful as a whole, and improve the overall visual effect of the product.

[0045] In a feasible embodiment of the utility model, the diameter of the drainage hole 3 is D, and 2mm < D < 8mm. The diameter of the drainage hole 3 directly affects the drainage speed and efficiency. If the diameter is too small, it may cause poor drainage, and if the diameter is too large, it may increase the wind resistance and reduce the overall performance of the fan. By setting the diameter of the drainage hole to be between 2mm and 8mm, it can ensure that the drainage hole 3 can effectively remove the water accumulated on the surface of the fan blade, and will not cause too much resistance to the airflow of the fan. By setting the diameter of the drainage hole to be between 2mm and 8mm, the overall structural strength of the fan blade can be ensured while the drainage performance is guaranteed.

[0046] Again referring to Figure 2 In a feasible embodiment of the utility model, the height of the wind blocking rib 4 protruding from the bottom surface is H, and 2mm < H < 8mm. If the wind blocking rib 4 is too high, it may increase the wind resistance, reduce the air supply efficiency of the fan, and produce additional noise. By setting the height of the wind blocking rib 4 to be between 2mm and 8mm, the resistance to the airflow can be minimized while maintaining the drainage performance, and the noise level can be reduced.

[0047] Again referring to Figure 2As shown, in a feasible embodiment of the present application, the fan blade structure 2 comprises a center plate 21, a ring body 22 and a plurality of fan blades 23, wherein the center plate 21 is circular, which is helpful for the uniform distribution of air flow. The diameter of the center plate 21 is greater than that of the motor 1, which not only provides sufficient support and protection for the motor and ensures the stability of the motor during operation, but also provides sufficient space for the drain holes 3 on the center plate to effectively remove the accumulated moisture. A plurality of drain holes 3 are formed in the center plate 21, and the plurality of drain holes 3 are uniformly distributed. The inner ring body 22 is connected to the outer periphery of the center plate 21 to form a solid frame, which helps to enhance the overall stability and durability of the fan blade structure 2.

[0048] The plurality of fan blades 23 are uniformly distributed on the outer periphery of the inner ring body 22, which helps to ensure the uniform distribution of air flow between the fan blades, thereby improving the air supply effect and efficiency of the fan.

[0049] Therefore, in the above embodiment, the fan blade structure 2 is combined by the center plate 21, the inner ring body 22 and the fan blades 23, which not only improves the air supply efficiency and stability of the fan, but also enhances the drainage performance, so that the fan blade structure 2 has more excellent performance and wider application prospect in the application scenario of the stationary air conditioner outdoor unit.

[0050] In a feasible embodiment of the present application, the fan blade structure 2 further comprises an outer ring body 24, one end of the fan blade 23 is connected to the inner ring body 22, and the other end of the fan blade 23 is connected to the outer ring body 24, forming a more stable structure, which can effectively enhance the overall strength of the fan blade and prevent the fan blade from deforming or damaging due to uneven stress during high-speed rotation. In addition, the outer ring body 24 helps to reduce the noise generated during the rotation of the fan blade, making the fan run more quietly. The double connection structure of the outer ring body 24 and the inner ring body 22 makes the fan blade more stable during rotation, which can reduce the vibration and shaking of the fan blade and improve the overall stability of the fan, thereby prolonging the service life of the fan.

[0051] In a feasible embodiment of the present application, the fan blade structure 2 further comprises an inclined annular plate 25, the inner side of the inclined annular plate 25 is connected to the center plate 21, and the outer side of the inclined annular plate 25 is connected to the inner ring body 22. The setting of the inclined annular plate 25 helps to guide the airflow to pass through the fan blade area more smoothly, and the inclined shape can produce a certain guiding effect, so that the airflow is more uniformly distributed between the fan blades, reducing the occurrence of airflow turbulence and vortex phenomenon, thereby improving the air supply efficiency and performance of the fan.

[0052] In summary, the fan of the stationary air conditioner outdoor unit provided by the present application can reduce wind noise and improve user comfort when the drain hole is blown by the wind during the rotation of the fan.
