An air conditioner, comprising:

• an outdoor unit comprising:
• a housing comprising a vent and an accommodating cavity, the vent being in communication with the accommodating cavity;
• and
• a fan arranged in the accommodating cavity and corresponding to the vent, wherein the fan comprises:
• a motor;
• and
• a fan blade, wherein the fan blade comprises a fixed portion and at least one blade, and the at least one blade is connected to an output portion of the motor through the fixed portion;
• wherein the at least one blade comprises a first edge portion arranged on a side of the at least one blade away from the fixed portion, and the first edge portion comprises a first sub-edge portion, a second sub-edge portion, and a third sub-edge portion;
• the first sub-edge portion is disposed at an end of the first edge portion that is close to a windward side of the at least one blade, the second sub-edge portion is disposed at an end of the first edge portion that is close to a leeward side of the at least one blade, and the third sub-edge portion is connected between the first sub-edge portion and the second sub-edge portion;
• a plane perpendicular to an axis of the fan blade is defined as a cross section of the fan blade, a projection of the first sub-edge portion on the cross section is a first circular arc, a projection of the second sub-edge portion on the cross section is a second circular arc, and a radius of the first circular arc is greater than a radius of the second circular arc.
