The present invention relates to a vent door whistle noise prevention structure of an automobile adduct.

일반적으로 자동차의 에어덕트는 도1에 도시된 바와 같이 하부의 공조유니트(1)로부터 송풍되는 에어를 실내의 중앙 부분과 좌우 끝부분으로 토출할 수 있도록 된 구조로 이루어져 있다. 즉, 상기 공조유니트(1)로부터 중앙과 좌우방향으로 덕트(2)가 연장 성형되어 있다.In general, the air duct of the vehicle is configured to discharge the air blown from the air conditioning unit (1) in the lower portion to the center and left and right ends of the room as shown in FIG. That is, the duct 2 is extended and formed in the center and the left-right direction from the said air conditioning unit 1.

한편, 상기 덕트(2)의 단부에는 토출되는 에어의 풍량과 방향을 조절하기 위한 구조가 적용되어 있는바, 도2에 도시된 바와 같이 벤트그릴(3)의 중앙과 측부에 풍향조절노브(4)와 풍량조절노브(6)가 설치된다.On the other hand, the end of the duct 2 is applied to the structure for adjusting the amount and direction of the air discharged, as shown in Figure 2 the wind direction control knob (4) in the center and side of the vent grill (3) ) And air volume control knob (6) is installed.

상기 풍향조절노브(4)는 벤트그릴(3)의 내측에 세로로 설치된 블레이드(5)를 좌우로 회전시켜 풍향을 조절할 수 있도록 되어 있으며, 상기 풍량조절노브(6)는 상하로 회전될 때 벤트그릴(3)의 내측에 설치된 벤트도어(7)를 상하로 회전시켜 덕트(2)의 출구를 개폐함으로써 풍량을 조절할 수 있도록 되어 있다.The wind direction adjusting knob 4 is configured to adjust the wind direction by rotating the blade 5 vertically installed inside the vent grill 3 to the left and right, and the air volume control knob 6 is vented when it is rotated up and down The vent door 7 provided inside the grill 3 is rotated up and down to open and close the outlet of the duct 2 so that the air volume can be adjusted.

상기 벤트도어(7)는 도3에 도시된 바와 같이, 덕트(2)의 내부에 힌지(8)를 중심으로 회동 가능하게 설치되어 있고, 상기 벤트도어(7)는 풍량조절노브(6)에 연동될 수 있도록 설치되어 있으며, 외측 둘레면에는 기밀을 유지하기 위한 고무립(9)이 설치되어 있다.As shown in FIG. 3, the vent door 7 is rotatably installed around the hinge 8 in the duct 2, and the vent door 7 is connected to the air volume control knob 6. It is installed to be interlocked, and the rubber lip 9 for maintaining the airtightness is provided on the outer peripheral surface.

한편, 상기 덕트(2)의 내부에는 고무립(9)에 접촉되는 돌기(2a)가 내측으로 돌출되게 형성되어 있다.On the other hand, the inside of the said duct 2 is formed so that the protrusion 2a which contacts the rubber lip 9 may protrude inward.

따라서, 상기 벤트도어(7)가 거의 닫힌 상태에서는, 에어가 덕트(2)의 돌기(2a)와 고무립(9) 사이의 좁은 틈을 통과하면서 가속되며, 이 가속된 에어가 상 기 틈을 빠져나온 후 불규칙하게 유동되면서 상기 고무립(9)을 진동시킴으로써 소음이 발생하게 되는데, 이 소음을 휘슬노이즈(whistle noise)라 한다.Therefore, in the state in which the vent door 7 is almost closed, air is accelerated while passing through the narrow gap between the projection 2a of the duct 2 and the rubber lip 9, and the accelerated air is closed to the gap. Noise is generated by vibrating the rubber lip 9 while being irregularly flowed after exiting, and this noise is called whistle noise.

상기 휘슬노이즈는 특정 주파수에 음향 에너지가 집중되어 나타나는 소음으로서 듣는 이에게 불쾌감을 주는 정도가 매우 강하며, 고무립(9)의 유동노출길이, 두께 및 형상에 따라서 정도와 범위의 차이는 있으나 상기와 같은 벤트도어(7)가 설치된 차량에서는 거의 모든 차종에서 발생하여 차량의 실내 정숙성을 저하시키는 문제점이 있었다.The whistle noise is a noise that is concentrated in a specific frequency, the sound energy is very unpleasant to the listener, the degree and range of the flow of the rubber lip (9) depending on the length and thickness, but the difference in the range In a vehicle in which the vent door 7 is installed, there is a problem that occurs in almost all types of vehicles, thereby lowering the indoor quietness of the vehicle.

여기에서 참조되는 바와 같이 본 발명은 공조유니트(1)로부터 송풍되는 에어를 실내의 중앙 부분과 좌우 끝부분으로 토출할 수 있도록 분기된 구조로 형성된 덕트(2)의 내부공간 즉, 각 분기된 단부의 내부 공간에는 그 덕트(2)의 내부 공간을 선택적으로 차단하기 위한 벤트도어(7)가 설치되어 있되, 상기 벤트도어(7)는 힌지(8)를 중심으로 회전가능하게 설치되어 있다.As referred to herein, the present invention is an internal space of the duct 2 formed in a branched structure so that air blown from the air conditioning unit 1 can be discharged to the center and left and right ends of the room, that is, each branched end. In the inner space of the vent door 7 for selectively blocking the inner space of the duct 2 is provided, the vent door 7 is rotatably installed around the hinge (8).

한편, 상기 벤트도어(7)의 중앙에는 공기가 이동하는 통공(7a)이 형성되어 있되, 그 통공(7a)은 적어도 2개 이상 복수개를 등간격으로 형성하는 것이 바람직하다.On the other hand, in the center of the vent door (7) is formed a through hole (7a) through which air moves, it is preferable to form at least two or more of the through holes (7a) at equal intervals.

또한, 상기 벤트도어(7)에는 실링패드(10)가 감싸여지게 설치되어 있되, 상기 실링패드(10)는 공기가 배출되는 방향의 벤트도어(7) 표면 및 둘레면에 감싸여지게 설치되어 있고, 상기 실링패드(10)는 공기에 의해서 확장 가능한 고무재질로 이루어져 있다. In addition, the vent door 7 is provided with a sealing pad 10 to be wrapped, the sealing pad 10 is installed to be wrapped around the surface and the circumferential surface of the vent door 7 in the air discharge direction The sealing pad 10 is made of a rubber material expandable by air.

이와 같이 구성된 본 발명을 상세히 설명하면 다음과 같다.Referring to the present invention configured as described in detail as follows.

먼저, 풍량조절노브(6)를 조작하면 벤트도어(7)는 덕트(2)의 내부에서 회전 하게 되는 것이고, 상기 벤트도어(7)가 수평상태로 회전되면 상기 덕트(2)를 통하여 이동하는 공기는 벤트그릴(3)을 통과하여 자동차 실내로 유입되는 것이다.First, when the air volume control knob 6 is operated, the vent door 7 rotates inside the duct 2, and when the vent door 7 is rotated in a horizontal state, the vent door 7 moves through the duct 2. Air passes through the vent grill 3 and enters the vehicle interior.

한편, 덕트(2)를 통하여 이동하는 공기를 차단할 때에는 벤트도어(7)가 수직방향 즉 도5에 나타낸 바와 같이 덕트(2)의 내부 공간을 차단하도록 회전시키는 것이며, 이때 덕트(2)를 통하여 이동하는 공기에 의해서 벤트도어(7)에 감싸여진 실링패드(10)가 확장되면서 덕트(2)의 내부에 돌출되게 형성된 돌기(2a)에 긴밀히 접촉되므로 덕트(2)의 내부 공간을 차단하게 된다.On the other hand, when the air moving through the duct 2 is blocked, the vent door 7 is rotated to block the internal space of the duct 2 in the vertical direction, that is, as shown in FIG. The sealing pad 10 wrapped in the vent door 7 by the moving air is in close contact with the protrusion 2a formed to protrude into the duct 2, thereby blocking the internal space of the duct 2. .

상술한 바와 같이 덕트(2)의 내부 공간이 차단되면, 벤트도어(7)의 단부와 돌기(2a)의 사이로 공기가 유입되지 않게되므로 휘슬노이즈(whistle noise)가 방지된다.As described above, when the internal space of the duct 2 is blocked, air does not flow between the end of the vent door 7 and the protrusion 2a, thereby preventing whistle noise.

이와 같이 본 발명은 덕트 내부에 돌출되게 형성된 돌기와, 상기 덕트에 회전 가능하게 설치된 벤트도어의 단부 사이의 틈새가 발생하지 않게 되므로 덕트 내부에서 이동하는 미세한 공기로 인한 휘슬노이즈가 방지되어 자동차 실내를 쾌적한 환경으로 유지할 수 있는 특유의 효과가 있다.As such, the present invention prevents a gap between the protrusion formed in the duct and the end of the vent door rotatably installed in the duct, thereby preventing whistle noise due to fine air moving inside the duct, thereby making the interior of the car comfortable. There are unique effects that can be maintained in the environment.
