[0026] It should be noted that the air conditioner outdoor unit fan blade 100 is applied to an air conditioner outdoor unit (not shown in the figure), which is installed outdoors and connected with an air conditioner indoor unit (not shown in the figure). The air conditioner outdoor unit and the air conditioner indoor unit jointly function to realize the function of regulating the indoor temperature. The air conditioner outdoor unit includes a condenser (not shown in the figure), a driving motor (not shown in the figure) and a shell (not shown in the figure), wherein the condenser, the driving motor and the air conditioner outdoor unit fan blade 100 are all installed in the shell. The driving motor is connected with the air conditioner outdoor unit fan blade 100 to drive the air conditioner outdoor unit fan blade 100 to rotate. The position of the air conditioner outdoor unit fan blade 100 corresponds to the position of the condenser, and the condenser is used for heat exchange of refrigerant. The air conditioner outdoor unit fan blade 100 can form negative pressure in the process of rotation to drive the air flow to form an air outflow, which is used for air cooling of the condenser to take away the heat of the condenser and ensure the normal operation of the condenser.

[0027] The air conditioner outdoor unit fan blade 100 includes a hub 110 and a blade 120. The hub 110 is in a cylindrical shape, and the blade 120 is fixedly connected to the peripheral surface of the hub 110. The hub 110 can drive the blade 120 to rotate, thereby driving the air flow. The hub 110 is used for connection with the driving motor, and the driving motor can drive the blade 120 to rotate through the hub 110.

[0028] In the embodiment, the number of blades 120 is three, and the three blades 120 are arranged in an annular array on the peripheral surface of the hub 110. The hub 110 can simultaneously drive the three blades 120 to rotate to make the air flow form an air outflow. However, it is not limited to this, and in other embodiments, the number of blades 120 can be four or five, and the number of blades 120 is not specifically limited.

Specifically, the blade 120 is in the form of a curved panel, and the blade 120 is first recessed towards the leeward side 126 in the direction from the inner edge 123 to the outer edge 124, and then recessed towards the windward side 125. The blade 120 arranged in the form of a curved panel can improve the stability of the air outlet of the air conditioner outdoor unit fan blade 100, ensure balanced air outlet, improve air outlet volume, and reduce noise.

[0031] Further, since the blade 120 is first recessed towards the leeward side 126 and then recessed towards the windward side 125, the blade 120 is divided into two parts in the direction from the inner edge 123 to the outer edge 124, the first part of the blade 120 is recessed towards the leeward side 126, and the second part of the blade 120 is recessed towards the windward side 125.

[0034] In this embodiment, the minimum angle of the blade 120 concave to the leeward side 126 is 168 degrees, but it is not limited to this. In other embodiments, the minimum angle of the blade 120 concave to the leeward side 126 can be 160 degrees or 170 degrees, and the minimum angle of the blade 120 concave to the leeward side 126 is not specifically limited.

Specifically, the middle part of the blade 120 is located at the intermediate position of the leading edge 121 and the trailing edge 122. In the second part of the blade 120, the concave angle of the trailing edge 122 is smaller than the concave angle of the middle part of the blade 120, and the concave angle of the middle part of the blade 120 is smaller than the concave angle of the leading edge 121, that is, in the second part of the blade 120, the trailing edge 122 has the largest concave degree, the middle part of the blade 120 has a smaller concave degree, and the leading edge 121 has the smallest concave degree. To gradually flatten from the trailing edge 122 to the leading edge 121 in the second part of the blade 120, thereby improving the wind guiding effect of the leading edge 121, and improving the stability of the air outlet from the trailing edge 122, ensuring balanced air outlet, and reducing noise.

[0036] It is worth noting that the minimum angle range of the blade 120 concave to the windward side 125 is 150-170 degrees, that is, in the second part of the blade 120, the concave angle of the trailing edge 122 ranges from 150 to 170 degrees, and a reasonable concave angle can further improve the wind guiding effect, improve the stability of the air outlet, and ensure balanced air outlet.
