Abstract:
A device for controlling diffused air comprising:an air outlet structure connected to a terminal end of an air path so as to diffuse air into ambient air;a flap arranged in the air outlet structure for deflecting a flow direction of the diffused air; andambient air drawing and mixing means for drawing the ambient air into the diffused air and mixing the ambient air with the diffused air;said ambient air drawing and mixing means being arranged in the air outlet structure so as to project into the diffused air and constituted by a plurality of three-dimensional structures configured to generate a vertical vortex in the diffused air;each said three-dimensional structure being constituted by a triangular or rectangular plate,wherein the plate includes a contacting side contacting the air outlet structure so that the contacting side is arranged so as to be set at substantially an angle of 10.degree.-30.degree. with respect to the flow direction,said plurality of three-dimensional structures are arranged at positions corresponding to vertical sections of the diffused air, andadjacent three-dimensional structures are arranged convergently so as to be plane-symmetrical to each other with respect to a plane parallel to the flow direction.
