Axial flow blade and air-conditioner provided with same

The invention discloses an axial flow blade and an air-conditioner provided with the same. Through holes are formed in the hub face of the axial flow blade. The through holes penetrate in the airflowcirculating direction. A wind shielding rib is arranged on the edge of each through hole and arranged on the tail wind side of each through hole. The wind shielding ribs and the rotating axial flow blade cooperate to guide wind into the through holes. The wind shielding ribs are of an arc-shaped curved surface structure. According to the axial flow blade, the through holes are additionally formedin the middle of a traditional axial flow blade structure, when the axial flow blade operates and rotates, the wind can be blown upwards through the through holes to cool a motor, and thus the servicelife of the motor is prolonged. When the wind is blown upwards by means of the through holes, dirt accumulated at the upper end of the axial flow blade can be blown away in time, and thus the problemthat in the prior art, due to dirt accumulation, the quality of parts of the axial flow blade and the motor assembling effect are reduced is solved. The through holes can also serve as water drainageholes, accumulated rainwater can be drained in time, and thus the axial flow blade cannot be damaged easily.
