Description

Air conditioner Technical Field The utility model relates to the technical field of air conditioners, in particular to an air conditioner. Background The air conditioner comprises an indoor unit and an outdoor unit, wherein the outdoor unit of the air conditioner comprises an axial flow fan, and the axial flow fan provides air circulation power. In order to ensure strength, the existing axial flow fan is provided with reinforcing ribs on fan blades. The reinforcing ribs have limited improvement effects on the running deformation and stress of the axial fan, but the flow condition of raw materials in a die cavity can not be changed during production, and the poor flowability of the raw materials can reduce the forming quality of the fan blade. The above information disclosed in this background section is only for enhancement of understanding of the background section of the application and therefore it may not form the prior art that is already known to those of ordinary skill in the art. Disclosure of utility model Aiming at the problems pointed out in the background art, the utility model provides an air conditioner, which improves the fluidity of raw materials in a die cavity during fan blade production and improves the molding quality of a fan.
