자동차 에어컨모듈의 송풍기 소음 저감구조Noise reduction structure of blower of automobile air conditioning module

본 고안은 자동차 에어컨모듈의 일부를 구성하고 있는 송풍기의 소음을 저감시키기 위한 자동차 에어컨모듈의 송풍기 소음 저감구조에 관한 것으로, 더 상세히는 송풍기의 구동시 송풍팬에 의해 발생되는 소음을 저감시켜 차실 분위기를 정숙하게 할 수 있도록 한 자동차 에어컨모듈의 송풍기 소음 저감구조에 관한 것이다.The present invention relates to a blower noise reduction structure of a car air conditioner module for reducing the noise of the blower constituting a part of the car air conditioner module, more specifically, to reduce the noise generated by the blower fan when driving the blower atmosphere It relates to a blower noise reduction structure of an automobile air conditioner module to make a quiet.

도 1은 에어컨모듈에 결합되는 일반적인 송풍기의 사시도이고, 도 2는 도 1의 단면도이다.1 is a perspective view of a general blower coupled to the air conditioner module, Figure 2 is a cross-sectional view of FIG.

도 1 및 도 2에 도시한 바와 같이, 자동차 에어컨모듈의 구성요소중에 하나인 송풍기(10)는 송풍팬(11)과 송풍모터(12)로 구성되며 외기유입구(21)와 내기유입구(22) 그리고 송풍구(23)가 형성된 에어컨모듈 하우징(20)에 일체식으로 결합된다. 이때 송풍팬(11)은 에어컨모듈 하우징(20) 내부에 위치되도록 결합되며 송풍모터(12)는 에어컨모듈 하우징(20)의 외부에 위치되도록 결합된다.1 and 2, the blower 10, which is one of the components of the vehicle air conditioner module, is composed of a blowing fan 11 and a blower motor 12, the air inlet 21 and the air inlet 22 And the air outlet 23 is integrally coupled to the air conditioning module housing 20 is formed. In this case, the blower fan 11 is coupled to be positioned inside the air conditioner module housing 20, and the blower motor 12 is coupled to be positioned outside the air conditioner module housing 20.

그리고 송풍기(10)의 작동시 공기는 송풍팬(11)이 회전에 의하여 외기유입구(21)나 내기유입구(22)로부터 송풍구(23)로 송풍되고 도시하지 않은 히터 코어나 증발기코어를 통과하면서 가열하거나 냉각된 후, 차실로 공급된다.When the blower 10 is operated, air is heated while the blower fan 11 is blown from the outside air inlet 21 or the inside air inlet 22 to the blower 23 by passing through a heater core or an evaporator core (not shown). Or after cooling, it is supplied to the compartment.

그런데, 송풍팬(11)의 외부를 둘러싸고 있는 에어컨모듈 하우징(20)이 경질의 플라스틱재로 되어 있기 때문에 송풍기(10)의 작동시 송풍팬(11)에서 발생되는 소음이 차실로 잘 전달되는 단점이 있었다.However, since the air conditioner module housing 20 surrounding the outside of the blower fan 11 is made of hard plastic material, the noise generated from the blower fan 11 during operation of the blower 10 is well transmitted to the vehicle compartment. There was this.

본 고안은 이러한 종래의 단점을 감안한 것으로, 송풍기의 구동시 송풍팬에 의해 발생되는 소음을 저감시킬 수 있는 구조로 개선하여 차실 분위기를 정숙하게 할 수 있는 자동차 에어컨모듈의 송풍기 소음 저감구조를 제공하고자 한다.The present invention has been made in view of the above disadvantages, and has been made to provide a structure for reducing the noise generated by the blower fan when driving the blower to reduce the noise of the vehicle air conditioner module to provide a blower noise reduction structure do.

본 고안은 송풍팬(110)과 송풍모터(120)로 구성되며, 상기 송풍팬(110)은 에어컨모듈 하우징(200) 내부에 위치되도록 결합되며 상기 송풍모터(120)는 에어컨모듈 하우징(200)의 외부에 위치되도록 결합되는 자동차 에어컨모듈의 송풍기(100)에 있어서, 상기 송풍팬(110)의 둘레를 에워싸도록 상기 에어컨모듈 하우징(200) 내면에 흡음재(300)를 부착시킨 것에 그 특징이 있다.The present invention consists of a blowing fan 110 and a blowing motor 120, the blowing fan 110 is coupled to be located inside the air conditioning module housing 200 and the blowing motor 120 is an air conditioning module housing 200 In the blower 100 of the vehicle air conditioning module coupled to be positioned outside of the, characterized in that the sound absorbing material 300 is attached to the inner surface of the air conditioning module housing 200 to surround the circumference of the blowing fan 110 have.

이하, 본 고안의 바람직한 실시예를 첨부된 도면을 참조하여 상세히 설명한다.Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail.

도 3은 본 고안에 따른 송풍기의 단면도이다.3 is a cross-sectional view of the blower according to the present invention.

도 3은 도시한 바와 같이, 흡음재(300)은 폴리우레탄폼 등 수지계열의 내열성 재료를 사용하여 송풍팬(110)의 주변에 부착시킨다.3, the sound absorbing material 300 is attached to the periphery of the blowing fan 110 using a resin-based heat-resistant material such as polyurethane foam.

송풍팬(110)이 에어컨모듈 하우징(200)의 내부에 위치되어 있으므로 에어컨모듈 하우징(200)의 내부에 흡음재(300)를 부착시키는 것이 소음저감효과를 높일 수 있으며, 흡음재(300)의 부착시에는 끼워맞춤식으로 고정하거나 접착제를 사용할 수도 있다.Since the blowing fan 110 is located inside the air conditioner module housing 200, attaching the sound absorbing material 300 to the inside of the air conditioner module housing 200 may increase the noise reduction effect, and when the sound absorbing material 300 is attached, The fitting may be fixed or adhesive may be used.

이러한 구조로 된 본 고안은 송풍기(100)의 작동시 공기는 송풍팬(110)이 회전에 의하여 외기유입구(210)나 내기유입기(220)로부터 송풍구(230)로 송풍되고 도시하지 않은 히터코어나 증발기코어를 통과하면서 가열되거나 냉각된 후, 차실로 공급된다. 이때 송풍팬(110)에 의해 발생된 소음을 에어컨모듈 하우징(200) 내면에 부착된 흡음재(300)가 저감시켜 주므로 소음이 차실로 잘 전달되는 것을 줄여주게 된다.According to the present invention having the above structure, the air is blown from the outside air inlet 210 or the air inlet 220 through the air inlet 210 through the rotation of the blower fan 110, and the heater core is not shown. Or heated or cooled while passing through the evaporator core and then supplied to the compartment. At this time, the noise generated by the blower fan 110 reduces the sound absorbing material 300 attached to the inner surface of the air conditioner module housing 200, thereby reducing noise being transmitted to the vehicle compartment.

상술한 바와 같이, 본 고안은 송풍기(100)의 구동시 송풍팬(110)에 의해 발생되는 소음을 저감시키기 위하여 에어컨모듈 하우징(200)에 흡음재(300)를 부착시킨 구조로써, 송풍기(100)의 작동시 차실로 소음이 전달되는 것을 줄여주므로 차실 분위기를 정숙해지는 효과가 있다.As described above, the present invention has a structure in which the sound absorbing material 300 is attached to the air conditioner module housing 200 in order to reduce noise generated by the blower fan 110 when the blower 100 is driven. This reduces noise transmission to the cabin during operation, which has the effect of quieting the cabin atmosphere.
