먼저, 본 발명에 따른 차량용 공조장치의 특징부를 살펴보기에 앞서, 도 2와 도 3을 참조하여 글로브 박스 공조기술에 대해 간략하게 살펴본다.First, before looking at the features of the vehicle air conditioning apparatus according to the present invention, a brief description of the glove box air conditioning technology with reference to FIGS. 2 and 3.

글로브 박스 공조 기술은, 열교환기(1) 하류측 공조케이스(3)부분에 공기인출구(5)를 형성하고, 형성된 공기인출구(5)와 글로브 박스(7)를 공기이송호스(8)로 연결한 구조이다.In the glove box air conditioning technology, an air outlet port 5 is formed in a portion of the air conditioning case 3 downstream of the heat exchanger 1, and the formed air outlet port 5 and the glove box 7 are connected by an air transfer hose 8 It is a structure.

이러한 글로브 박스 공조기술은, 열교환기(1) 하류측 공조케이스(3)의 냉풍을 공기인출구(5)로 인출하고, 인출된 냉풍을 공기이송호스(8)로 이송하여 글로브 박스(7)의 내부에 공급한다. 따라서, 글로브 박스(7)가 냉장고 기능을 수행할 수 있게 한다.This glove box air conditioning technology draws the cold air from the heat exchanger (1) downstream air-conditioning case (3) to the air outlet (5), and transfers the drawn cold air to the air transfer hose (8) to transfer the glove box (7). Supply inside. Therefore, the glove box 7 can perform the refrigerator function.

여기서, 공기인출구(5) 둘레의 공조케이스(3)부분에는, 결합니플(9)이 형성되어 있으며, 상기 결합니플(9)의 둘레에는 공기이송호스(8)가 끼워져 결합된다.Here, in the air-conditioning case 3 around the air outlet 5, a coupling nipple 9 is formed, and around the coupling nipple 9, an air transfer hose 8 is fitted and coupled.

다음으로, 본 발명에 따른 차량용 공조장치의 특징부를 도 2 내지 도 4를 참조하여 상세하게 살펴본다.Next, the features of the vehicle air conditioning apparatus according to the present invention will be described in detail with reference to FIGS. 2 to 4.

먼저, 본 발명의 공조장치는, 공조케이스(3)의 공기인출구(5)와 공기이송호스(8) 부분에서 발생되는 특정 주파수의 휘슬소음을 감소시키기 위한 소음감소부(10)를 더 구비한다.First, the air conditioning apparatus of the present invention further includes a noise reduction unit 10 for reducing whistle noise of a specific frequency generated in the air outlet 5 and the air transfer hose 8 of the air conditioning case 3 .

소음감소부(10)는, 공조케이스(3)의 공기인출구(5)측에 형성되는 적어도 하나 이상의 돌출돌기(12)를 포함한다.The noise reduction unit 10 includes at least one protruding protrusion 12 formed on the air outlet 5 side of the air conditioning case 3.

돌출돌기(12)는, 공기인출구(5)측의 결합니플(9) 내측에 형성된다. 특히, 결합니플(9)의 내주면 끝부분으로부터 내측의 내부공기유로(9a)를 향해 돌출 형성되어 있다.The protruding protrusion 12 is formed inside the coupling nipple 9 on the air outlet port 5 side. In particular, the inner nipple of the coupling nipple 9 is formed to protrude toward the inner air passage 9a inside.

더욱 상세하게는, 돌출돌기(12)가, 결합니플(9)의 끝부분에 돌출되게 형성되어 있되, 공기이송호스(8)와의 경계부분에 대응되는 부분에 형성되어 있다.More specifically, the protruding projection 12 is formed to protrude at the end of the coupling nipple 9, but is formed at a portion corresponding to the boundary portion with the air transfer hose 8.

이러한 돌출돌기(12)는, 공조케이스(3)의 냉풍이 공기인출구(5)와 공기이송호스(8)로 인출될 시에, 상기 공기인출구(5)와 공기이송호스(8)측에서 발생되는 소음의 특정대역 음파 주파수를 교란시킨다.When the cold air of the air conditioning case 3 is drawn out through the air outlet 5 and the air conveying hose 8, the protruding protrusion 12 is generated at the air outlet 5 and the air conveying hose 8 side. It disturbs the sound frequency of a specific band of noise.

특히, 공기인출구(5)와 공기이송호스(8)로의 냉풍 인출 과정에서, 공기인출구(5)의 결합니플(9)과 공기이송호스(8) 경계부분에는 특정 주파수 대역의 음파가 음장(Sound Field)(A)을 형성하면서 휘슬소음의 근원을 이루는데, 이때, 결합니플(9)의 돌출돌기(12)는, 음장(A)에 대한 특정 주파수의 통과 여부를 차등화하여 교란시킨다.In particular, in the process of drawing cold air to the air outlet 5 and the air transfer hose 8, sound waves of a specific frequency band are sound field at the boundary between the coupling nipple 9 and the air transfer hose 8 of the air outlet 5 While forming the field (A), it forms the source of whistle noise. At this time, the protruding protrusions 12 of the coupling nipple 9 differentiate and disturb the passage of a specific frequency with respect to the sound field A.

따라서, 휘슬소음의 근원이 되는 음장(A)의 형성을 방해한다. 이로써, 공기인출구(5)의 결합니플(9)과 공기이송호스(8) 경계부분에서 발생되는 특정 주파수의 휘슬소음을 최소화시킨다.Therefore, the formation of the sound field A, which is the source of whistle noise, is prevented. Accordingly, whistle noise of a specific frequency generated at the boundary portion of the coupling nipple 9 and the air transfer hose 8 of the air outlet 5 is minimized.

그 결과, 글로브 박스(7)로의 공기인출 과정에서 발생되는 휘슬소음을 개선시킬 수 있다. 이로써, 차실내로 전달되는 소음을 최소화시키고, 이를 통해, 차실내의 승차감과 쾌적성을 현저하게 개선시킨다.As a result, whistle noise generated in the air drawing process to the glove box 7 can be improved. As a result, noise transmitted to the interior of the vehicle is minimized, and through this, ride comfort and comfort in the interior of the vehicle are significantly improved.

한편, 이러한 구성의 돌출돌기(12)는, 결합니플(9)의 끝부분으로부터 내측의 내부공기유로(9a)를 향해 돌출되어 있되, 상기 결합니플(9)의 내주면을 따라 원주방향으로 일정 간격을 두고 다수개 형성되는 것이 바람직하다.On the other hand, the protruding projection 12 of this configuration, protrudes toward the inner air flow path 9a of the inner side from the end of the coupling nipple 9, but at regular intervals along the inner circumferential surface of the coupling nipple 9 It is desirable to form a plurality.

다시, 도 2 내지 도 4를 참조하면, 본 발명의 공조장치는, 공기인출구(5)의 결합니플(9)에 형성되는 적어도 하나 이상의 결합돌기(20)를 더 구비한다.Referring again to FIGS. 2 to 4, the air conditioning apparatus of the present invention further includes at least one coupling protrusion 20 formed on the coupling nipple 9 of the air outlet 5.

결합돌기(20)는, 결합니플(9)의 외주면부분에 형성되어 있다. 특히, 결합니플(9)의 외주면부분 중, 공기이송호스(8)와의 경계부분에 대응되는 부분에 형성되어 있다.The engaging projection 20 is formed on the outer peripheral surface portion of the engaging nipple 9. In particular, the outer peripheral surface portion of the coupling nipple 9 is formed in a portion corresponding to the boundary portion with the air transfer hose (8).

이러한 결합돌기(20)는, 공기인출구(5)의 결합니플(9)에 공기이송호스(8)를 끼워 결합시켰을 시에, 상기 공기이송호스(8)의 내주면에 걸리면서 결합니플(9)과 공기이송호스(8)간의 결합력을 높인다.The coupling protrusion 20 is engaged with the coupling nipple 9 while being caught by the inner circumferential surface of the air transportation hose 8 when the air delivery hose 8 is fitted into the coupling nipple 9 of the air outlet 5. Increase the bonding force between the air transfer hoses (8).

특히, 결합돌기(20)는, 공기인출구(5)의 결합니플(9)에 공기이송호스(8)를 끼워 결합시키는 과정에서, 공기이송호스(8)의 내주면을 파고들면서 공기이송호스(8)의 내주면에 걸리게 되는데, 이렇게 걸린 결합돌기(20)는, 결합니플(9)과 공기이송호스(8) 사이의 결합력을 높인다. 따라서, 결합니플(9)과 공기이송호스(8)가 서로 분리되는 것을 방지한다.In particular, the engaging projection 20, in the process of fitting the air transfer hose (8) to the coupling nipple (9) of the air outlet (5), while digging the inner circumferential surface of the air transfer hose (8), the air transfer hose (8) ) Is caught on the inner circumferential surface of the coupling protrusion 20 so as to increase the coupling force between the coupling nipple 9 and the air transfer hose 8. Therefore, the coupling nipple 9 and the air transfer hose 8 are prevented from being separated from each other.

뿐만 아니라, 결합돌기(20)는, 결합니플(9)의 끝부분에 형성되므로, 결합니플(9)의 끝부분과 공기이송호스(8) 사이의 경계부분에 대한 양자의 결합도를 현저하게 높여준다.In addition, since the coupling protrusion 20 is formed at the end of the coupling nipple 9, the degree of coupling of both of them to the boundary between the end of the coupling nipple 9 and the air transfer hose 8 is remarkably Enhance it.

따라서, 결합니플(9)의 끝부분과 공기이송호스(8) 사이에서 발생되는 간극과 틈새의 발생을 최대한 억제한다.Therefore, the generation of gaps and gaps generated between the end of the coupling nipple 9 and the air transfer hose 8 is suppressed as much as possible.

이로써, 결합니플(9)과 공기이송호스(8) 사이의 간극과 틈새로 인한 "휘슬소음"의 발생을 현저하게 저감시킨다.Thereby, the occurrence of "whistle noise" due to the gap and the gap between the coupling nipple 9 and the air transfer hose 8 is significantly reduced.

그 결과, 글로브 박스(7)로의 공기인출 과정에서 발생되는 "휘슬소음"을 개선하여, 차실내의 승차감과 쾌적성을 개선시킨다.As a result, the "whistle noise" generated in the air drawing process to the glove box 7 is improved to improve ride comfort and comfort in the cabin.
