Variable discharge grill for room air conditioner

摘要

A variable discharge grille assembly is arranged in an air discharge opening of a room air conditioner. The assembly includes a frame surrounding the air discharge opening and a louvered air deflecting grille arranged in the frame. The louvered air deflecting grille is pivotally supported on the air discharge opening frame, and a built-in stop feature keeps the grille from coming out of the frame during operation. The position variations of the air deflecting grille relative to the air discharge opening frame is accomplished by a rachet arrangement that includes a yieldable finger on the grille which snaps into detents formed on the frame surrounding the air discharge opening.
