Air-conditioner having outlet structure for reducing air turbulence noise

摘要

An outlet structure for an air-conditioner has a fan guard disposed on the outlet side of the air-conditioner for preventing foreign matter from entering to an air blower, and at least one air-direction control vane disposed upstream and/or downstream of the fan guard. The fan guard has elements, except for an outer frame, not in parallel to the rear edge of the upstream air-direction control vane or the front edge of the downstream air-direction control vane. Even in the case where the distance between a fan guard and air-direction control vanes is reduced, and airflows interfere with the fan guard and the air-direction control vanes as the size of air-conditioners is progressively reduced, air-turbulence noise may be reduced.
