AIR VENT FOR VENTILATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide an air vent feeding a distributed diffusion air stream capable of varying a main flow direction in a vertical wide direction range each other. SOLUTION: The air vent has a ball-like exit grid (14) as a whole. This exit grid is rotatably mounted to one end of an air duct (12) so as to be rotated making a central part as a center. Each of a large number of exit openings of the grid is directed to a different direction from others so that the diffusion air stream is obtained. The main direction of the air stream can be varied over a wide range by rotating the ball-like grid making the central part of the spherical shape as a center. COPYRIGHT: (C)2004,JPO
