Abstract

PURPOSE:To enable a wide deflection of blowoff air flowing from an air conditioner, by a method wherein at least a pair of movable vanes, which can move in the direction perpendicular to a wall surface and in the horizontal direction, are positioned facing and opposite to each other at the wall surface of a plane part of a blowoff port which has the plane part and a curve part. CONSTITUTION:In case a pair of upper and lower movable vanes 2a and 2b are in contact with upper and lower wall surfaces 1a, a blowoff current 3 does not deflect but flows in a horizontal direction. But, if one of the movable vanes, for example, the vane 2b moves away from the plane wall surface 1a in the perpendicular direction to form a gap 4 between the vane and the wall surface 1a, a blowoff current 3a, passing through the gap 4, flows curving downward along a wall surface 1b of a curved part, and a blowoff current 3c, flowing along the movable vane 2a, is exfoliated at the rear of the movable vane 2a to become in an unstable condition. Thus current 3c is pulled by the current 3a to form a current directing downward, and is deflected. If the movable vane 2a is moved like the above, a blowoff current can be deflected upward. This permits a wide deflection of an air blowoff direction of an air conditioner.
