Abstract
Official abstract text for this publication.
The present invention relates to a wind direction controlling device of a slim-type air vent for an automobile. More specifically, an air distributor and an air guide are mounted to an air duct of the slim-type air vent to make it easy to adjust the discharge volume and the vertical discharge angle of air discharged through a discharge portion of the air duct. The present invention comprises: a slim air duct ( 100 ) having an air inlet ( 110 ) and an air outlet ( 120 ) which pass therethrough, wherein air generated in an air conditioning device flows in through the air outlet ( 120 ) and then is discharged to the outside through the air outlet ( 120 ); an air distributor ( 200 ) rotatably installed inside the slim air duct ( 100 ); and an air guide ( 300 ) installed and fixed inside the air duct ( 100 ) so that the air distributed by the air distributor ( 200 ) is discharged through the air outlet ( 120 ) as the Coanda effect is generated in the upward-forward and downward-forward directions.
First claim
Opening claim text (preview).
The invention claimed is: 1 . A wind direction controlling device of a slim-type air vent for an automobile, the wind direction controlling device comprising: a slim-type air duct ( 100 ) having an air inlet ( 110 ) and an air outlet ( 120 ) through which air passes, wherein air generated in by air conditioning device flows in through the air inlet ( 110 ) and then is discharged to the outside through the air outlet ( 120 ), an air distributor ( 200 ) rotatably installed inside the slim-type air duct ( 100 ), and an air guide ( 300 ) installed and fixed inside the slim-type air duct ( 100 ) so that the air distributed by the air distributor is discharged through the air outlet ( 120 ) as the Coanda effect is generated in the upward-forward and downward-forward directions, wherein the air guide ( 300 ) has a curved contact surface ( 310 ) on one side, curvature of the contact surface ( 310 ) is the same as curvature of a body ( 210 ) of the air distributor ( 200 ) and an airfoil ( 320 ) protruding curvedly on the other side, air passages ( 230 ) in the body ( 210 ) of the air distributor ( 200 ) open and close depending on the position of the air passages ( 230 ) in contact with the contact surface ( 310 ) of the air guide ( 300 ) so that air may be supplied to only one of upper and lower parts of the slim-type air duct ( 100 ) or to both the upper and lower parts of the slim-type air duct ( 100 ) at the same time. 2 . The wind direction controlling device of claim 1 , wherein the air distributor ( 200 ) comprises a body ( 200 ) of a cylindrical shape having an air inflow region ( 211 ) through which air flows in, a hinge shaft ( 200 ) protruding on both left and right sides of the body ( 210 ), and a plurality of air passages ( 230 ) penetrating in the lateral direction of the body ( 210 ) rotating around the hinge shaft ( 220 ). 3 . The wind direction controlling device of claim 1 , wherein the air distributor ( 200 ) is configured to control the volume of air flowing in the slim-type air duct ( 100 ) as the air inlet ( 110 ) of the slim-type air duct ( 100 ) opens and closes depending on the rotating state of the air distributor ( 200 ).
