Opening angle adjusting apparatus of an automatic suction grille

摘要

An air conditioner cabinet includes an air inlet and an air outlet. A U-shaped frame is mounted to the cabinet such that parallel vertical legs of the frame straddle the inlet. A pair of links are arranged for vertical sliding movement adjacent respective ones of the legs. Vertically spaced blades are mounted to the frame and extend across the inlet. The blades are mounted to the links such that vertical movement of the links causes the blades to pivot between inlet-opening and inlet-closing positions. The blades pivot through different respective angles whereby the inlet is opened by progressively greater amounts from the top to the bottom of the inlet.
