Air-conditioner having outlet structure for reducing air turbulence noise

摘要

A fan guard (19) is disposed on the outlet side of the air-conditioner for preventing foreign matter from entering to an air blower (8), and at least one air-direction control vane (3) disposed upstream and/or downstream of the fan guard (19). The fan guard has elements (2), except for an outer frame (1), not in parallel to the rear edge of the upstream air-direction control vane (3) or the front edge of the downstream air-direction control vane (3). Alternatively, elements (10) in a given range are formed differently from the other elements (2). Even in the case where the distance between a fan guard (19) and air-direction control vanes (3) 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.
