AIR FLOW MODIFICATION DEVICE FOR AIR CONDITIONERS, INDOOR UNIT COMPRISING SAME AIR FLOW MODIFICATION DEVICE, AND AIR CONDITIONER COMPRISING SAME INDOOR UNIT

摘要

An air flow modification device for air conditioners comprises a rectangular frame that forms an opening, a plurality of horizontal air flow plates that are disposed in the frame opening in a line, and a connection plate that connects the plurality of horizontal air flow plates. The horizontal air flow plates comprise end air flow plates and one or more center air flow plates that are disposed between the end air flow plates. The end air flow plate comprises an end front air flow plate and an end back air flow plate that revolves in the direction opposite to the direction in which the end front air flow plate revolves and that is connected to the end front air flow plate so as to freely revolve. The center air flow plate comprises a center front air flow plate and a center back air flow plate that revolves in the direction opposite to the direction in which the center front air flow plate revolves and that is connected to the center front air flow plate so as to freely revolve. The connection plate engages and revolves the end front air flow plates, the end back air flow plates, the center front air flow plate, and the center back air flow plate. The angle through which the end front air flow plate revolves is smaller than the angle through which the center front air flow plate revolves, and the angle through which the end back air flow plate revolves is smaller than the angle through which the center back air flow plate revolves.
