ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an air vent system and more particularly to an air vent system installed at a door of an automobile.
2. Description of the Prior Art
In general, there is an air conditioning apparatus for circulating and purifying room air in an automobile.
The air conditioning apparatus includes a blower assembly for absorbing and exhausting room air out, an air duct formed to allow air to be supplied from the blower assembly and to be exhausted at a plurality of parts of crush pad and floor and a defroster.
Particularly, the air passing through the air duct is to be further supplied to an opening and closing part, a door. As shown in
FIGS. 6 and 7
, an air vent system includes a door duct
52
installed with an inlet
50
at the upper end of a door trim T for being closely aligned with a duct (not shown) of a crush pad C when a door is closed and an outlet close to the door trim T and a tightening pad
53
positioned at the inlet
50
to be tightly attached to the crush pad C.
Also, control means is assembled near the outlet
51
of the door duct
52
for controlling an air exhausting direction. The control means includes a grill
54
mounted at the outlet
51
to make vertical rotations, a plurality of blades
55
to make horizontal rotations toward the grill
54
, a grill handle
56
mounted to rotate the blades
55
and a horizontal handle
57
.
If the door is closed, the tightening pad
53
of the inlet
50
is tightly attached to the crush pad C and air is supplied to the door duct
52
through the duct of the crush pad C.
The air supplied to the door duct is then exhausted out through the grill
54
and blades
55
in a predetermined direction.
However, there is a problem in the conventional air vent system in that, when air is exhausted through the door duct installed at the door as described above, it is possible to move the blades and grill to control the air exhausting direction, but impossible to completely block the air duct and to avoid being exposed to the air exhausting out.
SUMMARY OF THE INVENTION
The present invention is disclosed to solve the aforementioned problems and it is an object of the present invention to provide an air vent system for a door of an automobile to allow a passenger to avoid undesired exposure to the air by completely blocking the air duct.
In order to accomplish the aforementioned objects of the present invention, there is provided an air vent system for a door of an automobile having a door duct installed at a door with an inlet that is to be tightly aligned to a duct of a crush pad when the door is closed and an outlet formed to a predetermined direction of the door and control means installed in a front side of the door duct to control an air exhausting direction, the system comprising:
a damper arranged in the center of the door duct for opening and closing the door duct at the time of its rotations;
a damper knob coupled with a rotary axis at an edge of the door duct to be rotated; and
link means connecting damper and damper knob which is rotated to allow the damper to open and close the door duct.
