Description
본 발명은 자동차용 에어필터에 관한 것으로서, 보다 상세하게는, 자동차의공기유입구에 설치되어 차량내부로 유입되는 오염된 외부 공기를 정화하는 자동차용 에어필터에 관한 것이다.The present invention relates to an automobile air filter, and more particularly, to an automobile air filter installed at an air inlet of an automobile to purify polluted external air introduced into the vehicle.
일반적으로 자동차의 차량내부로 유입되는 대기 중의 공기에는 먼지는 물론 알레르기를 유발하는 꽃가루, 분진, 미세 세균 그리고 악취 등이 포함되어 있으며, 이와 같이 오염된 외부의 공기를 정화하지 않고 밀폐된 차량내부로 유입시킨다면 운전자를 비롯한 탑승자들에게 불쾌감과 아울러 호흡곤란 등과 같은 인명 건강상에 치명적인 해를 끼칠 수 있으므로, 자동차 외부 대기 중의 공기에 포함되어 있는 먼지나 분진, 그리고 세균성 유해물질들을 가급적 제거된 상태에서 자동차 내부로 유입될 수 있도록 하여야 한다. 이를 위하여 자동차 외부의 공기가 유입되는 통로, 예를 들면 자동차 공조장치 내의 공기유입구 등에 자동차용 에어필터를 장착하여 먼지 또는 분진 등을 제거하게 되는데, 자동차용 에어필터는, 대기 중에 포함되어 있으면서 인체에 질병을 유발하는 미세 입자들을 자동차의 공조장치 내에서 자동차의 외기 유입모드 또는 내부순환모드 작동 시에 여과시키는 기능을 하게 된다Generally, the air in the air flowing into the vehicle's vehicle contains dust, pollen, dust, fine bacteria, and odors, which cause allergies. Inflow can also cause discomfort to drivers and passengers, as well as fatal health effects such as shortness of breath. Therefore, it is necessary to remove dust, dust and bacterial harmful substances contained in the air outside the car. It should be allowed to enter inside. To this end, a vehicle air filter is installed in a passageway through which air outside the vehicle enters, for example, an air inlet inside an automobile air conditioner to remove dust or dust. It will function to filter disease-causing fine particles in the vehicle air inflow mode or the internal circulation mode in the vehicle air conditioner.
그런데, 이러한 종래의 자동차용 에어필터는, 일반적으로 단순한 부직포나 합성섬유를 필터프레임에 고정시켜 외부의 공기가 필터프레임에 결합된 단순한 부직포나 합성섬유를 통과하면서 정화되도록 구성되어 있는데, 이와 같이 단순한 부직포나 합성섬유를 사용함으로써 외부 공기 중에 포함된 크기가 다소 큰 먼지 또는 분진 등의 제거는 가능하나 미세한 먼지나 분진 등은 포집하지 못하며, 단순한 부직포나 합성섬유에 곰팡이등 세균류가 번식하게 되고 불쾌한 냄새가 발생된다. 따라서 종래의 자동차용 에어필터로는 에어필터에 이차적으로 서식할 수 있는 세균의증식을 억제하거나 냄새를 제거하는 기능을 수행하기에는 부족한 문제점이 있었다.However, such a conventional air filter for automobiles is generally configured to fix a simple nonwoven fabric or synthetic fiber to the filter frame so that outside air is purified while passing through a simple nonwoven fabric or synthetic fiber bonded to the filter frame. By using nonwoven fabric or synthetic fiber, it is possible to remove dust or dust that is a little larger in the outside air, but it cannot collect fine dust or dust.Bacteria such as molds grow on simple nonwoven fabric or synthetic fiber and have an unpleasant odor. Is generated. Therefore, the conventional automotive air filter has a problem that it is insufficient to perform the function of suppressing the growth of bacteria that can inhabit secondary to the air filter or to remove the odor.
또한 이러한 문제점을 해결하기 위하여, 공기를 정화시키며 음이온을 방출하고 항균 및 소취작용을 하는 숯을 공기유입구에 설치하는 기술이 소개되었으나, 이 기술의 경우에는 숯을 덩어리로 공기유입구에 넣기 때문에 부피를 많이 차지하게 되는 점, 숯가루 등이 실내로 유입되어 탑승자의 입속으로 들어가는 점, 설치된 숯을 교환하기가 불편한 점 등 여러 가지 문제점이 있었다.In addition, in order to solve this problem, a technology of purifying air, releasing anions, and installing antibacterial and deodorizing charcoal at the air inlet has been introduced, but in the case of this technology, the volume of the char is put into the air inlet as a mass. There are various problems such as occupy a lot, charcoal powder is introduced into the room and enters the occupant's mouth, it is inconvenient to exchange the installed charcoal.
따라서, 본 발명의 목적은, 종래의 이러한 문제점을 해결하기 위하여, 자동차 외부의 대기 중에 포함된 미세한 먼지 또는 분진을 포집할 수 있으며 에어필터에 이차적으로 서식할 수 있는 각종 세균의 증식을 억제하고 냄새를 제거하여 위생적이고 쾌적한 공기가 자동차 실내에 유입되도록 할 수 있는 자동차용 에어필터를 제공하는 것이다.Accordingly, an object of the present invention, in order to solve this problem of the prior art, to collect the fine dust or dust contained in the atmosphere outside the vehicle and to suppress the odor and suppress the growth of various bacteria that can inhabit secondary to the air filter It is to provide a car air filter that can remove the hygienic and comfortable air flow into the car interior.

이하에서는 첨부도면을 참조하여 본 발명에 대해 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
도 1은 본 발명의 일 실시 예에 따른 자동차용 에어필터의 사시도이고, 도 2는 절곡참숯부직포의 사시도로서, 이들 도면에 도시된 바와 같이, 본 발명의 일 실시 예에 따른 자동차용 에어필터(1)는, 소정 간격을 두고 지그재그로 절곡시킨 절곡참숯부직포(10)와, 절곡참숯부직포(10)의 테두리부(11)를 따라 절곡참숯부직포(10)를 수용결합시키는 필터프레임(20)을 포함한다. 여기서 절곡참숯부직포(10)는 단위 면적당 공기와의 접촉면적을 증가시키기 위하여 참숯부직포를 길이방향으로 연속해서 삼각파형으로 절곡시킨 것으로서, 거의 사각형상의 필터프레임(20)의 내측에 위치하여 결합되어 필터프레임(20)에 의해 수용지지된다.1 is a perspective view of a vehicle air filter according to an embodiment of the present invention, Figure 2 is a perspective view of a bending charcoal nonwoven fabric, as shown in these drawings, the vehicle air filter according to an embodiment of the present invention ( 1) is a filter frame 20 for accommodating the bending charcoal nonwoven fabric 10 is bent in a zigzag at a predetermined interval and the bending charcoal nonwoven fabric 10 along the edge 11 of the bending charcoal nonwoven fabric 10 Include. Here, the bent charcoal nonwoven fabric 10 is a charcoal nonwoven fabric continuously bent in a triangular wave shape in the longitudinal direction in order to increase the contact area with air per unit area, and is located and coupled to the inside of the substantially rectangular filter frame 20 to filter It is received and supported by the frame 20.
본 발명에서는, 에어필터의 부직포 또는 합성섬유에 서식할 수 있는 세균의 번식을 억제하고 냄새를 제거하기 위하여 참숯원료의 성질을 이용하는데, 참숯원료는 원적외선, 음이온을 방출하고 습도를 조절하며 냄새를 제거하는 등 다양한 효능이 있음은 이미 공지의 사실이다. 이러한 참숯의 효능을 에어필터에 접목시키기 위하여 사용되는 참숯부직포는, 일반 부직포와 달리 참숯원료가 폴리에스테르 섬유 등의 합성섬유에 첨가된 것으로서, 참숯원료가 합성섬유에 완벽하게 접착되도록 하는 것이 난이하기 때문에 비닐계 또는 에폭시계와 같은 합성고분자 접착제를 첨가하고 초음파 융착을 통하여 제작된다. 이를 자세히 설명하면, 합성고분자 접착제 1∼6wt%와, 참숯원료 10∼25wt%와, 합성섬유 69∼89wt%의 합성섬유를 초음파 융착시키고 니들펀칭(Needle Punching)에 의해 2차원적인 랜덤한 섬유배열의 일부를 3차원적인 랜덤구조로 결합시키면 참숯부직포가 제작된다. 이 참숯부직포를 적당한 크기로 절단한 후, 약 150℃∼250℃의 온도 하에서 길이방향으로 지그재그로 절곡하면 도 2에 도시된 바와 같이 절곡부(13)를 갖는 절곡참숯부직포(10)가 제작되게 된다. 절곡 시에 약 150℃∼250℃의 온도를 유지하기 위해서, 절곡기계(미도시)의 상하에 히터를 설치하고 소정의 온도로 설정된 히터를 설정하여 작동시키고 절곡참숯부직포(10) 주위로 뜨거운 공기가 가도록 바람을 불게하는 방법이 사용되고 있다.In the present invention, in order to suppress the breeding of bacteria that can inhabit the non-woven fabric or synthetic fibers of the air filter and to remove the smell, the charcoal raw material is far infrared rays, negative ions to control the humidity and smell It is already known that there are various effects such as elimination. Charcoal non-woven fabric used to combine the efficacy of the charcoal in the air filter, unlike the normal non-woven fabric is a true charcoal raw material is added to the synthetic fibers, such as polyester fibers, it is difficult to ensure that the true charcoal raw material is completely bonded to the synthetic fibers Therefore, a synthetic polymer adhesive such as vinyl or epoxy is added and manufactured by ultrasonic fusion. In detail, 1 to 6 wt% of synthetic polymer adhesive, 10 to 25 wt% of true charcoal raw material, and 69 to 89 wt% of synthetic fiber are ultrasonically fused and needle-punching to produce a two-dimensional random fiber arrangement. When combined with a three-dimensional random structure of the charcoal non-woven fabric is produced. After cutting the charcoal nonwoven fabric into a suitable size, when bending in a longitudinal direction at a temperature of about 150 ℃ to 250 ℃ zigzag in a longitudinal direction so that the bent charcoal nonwoven fabric 10 having a bent portion 13 as shown in FIG. do. In order to maintain a temperature of about 150 ℃ to 250 ℃ at the time of bending, install a heater above and below the bending machine (not shown), set the heater set to a predetermined temperature to operate and hot air around the bending charcoal nonwoven fabric 10 The way to blow the wind is used.
초음파 융착은, 초음파 진동 에너지가 혼을 통하여 용착물에 전달되면 용착물의 접합면에서 순간적인 마찰열이 발생하여 융착물이 용해 접착되어 강력한 분자적 결합이 이루어도록 하는 공정으로서, 참숯원료를 합성섬유에 접합시킬 때 사용되는 합성고분자 접착제의 한계를 극복하기 위하여 실시되는 공정이다. 따라서 초음파 융착을 하게되면, 합성고분자 접착제에 의하여 참숯원료가 접착된 합성섬유 속에 초음파 에너지가 전달되어 합성섬유 상호간이나 참숯원료 상호간의 미세한 융착이 발생되게 되어 미세한 구멍들이 복잡하게 얽히게 됨으로써, 일반 부직포보다 더 미세한 먼지 또는 분진들의 통과를 억제할 수 있게 된다. 그리고 니들펀칭(Needle Punching)은 직물을 기계적으로 결합하는 부직포 제조방법의 하나로서, 이로써 2차원적인 랜덤한 섬유배열의 일부가 3차원적인 랜덤구조로 결합되는 참숯부직포가 제작되게 된다. 이와 같이 초음파 융착과 니들펀칭을 통해 제작된 참숯부직포는 일반 부직포보다 생성되는 구멍이 미세해 질뿐만 아니라 각 구멍이 상호 복잡하게 얽히게 되어 외부로부터 유입되는 미세한 먼지나 분진을 제거할 수 있게 된다.Ultrasonic fusion is a process in which when the ultrasonic vibration energy is transmitted to the deposit through the horn, instantaneous frictional heat is generated at the bonding surface of the deposit, so that the fusion is melted and bonded to form a strong molecular bond. In order to overcome the limitations of the synthetic polymer adhesive used when bonding. Therefore, when ultrasonic welding is performed, ultrasonic energy is transferred to the synthetic fiber to which the true charcoal raw material is bonded by the synthetic polymer adhesive, so that fine fusion is generated between the synthetic fibers or the charcoal raw material, and the fine pores are complicatedly intertwined. It is possible to suppress the passage of finer dust or dust. And needle punching (Needle Punching) is one of the non-woven fabric manufacturing method for mechanically bonding the fabric, thereby producing a charcoal non-woven fabric in which a part of the two-dimensional random fiber array is combined in a three-dimensional random structure. In this way, the charcoal nonwoven fabric produced through ultrasonic welding and needle punching not only becomes finer holes than general nonwoven fabrics, but also makes each hole intricately intertwined to remove fine dust or dust introduced from the outside.
도 3은 도 1의 평면도이고, 도 4는 도 3의 Ⅳ-Ⅳ에 따른 단면도로서, 이들 도면에 도시된 바와 같이, 필터프레임(20)은 절곡참숯부직포(10)를 수용지지하는 몸체(21)와, 몸체(21)의 길이방향의 일측 단부에 마련되는 손잡이(23)를 갖는다.Figure 3 is a plan view of Figure 1, Figure 4 is a cross-sectional view according to IV-IV of Figure 3, as shown in these figures, the filter frame 20 is a body 21 for receiving and supporting the bending charcoal nonwoven fabric 10 ), And a handle 23 provided at one end portion in the longitudinal direction of the body 21.
필터프레임(20)은 사출성형에 의하여 제작되는데, 폴리프로필렌 등의 플라스틱을 약 200℃로 알맞게 가열하여 용융상태로 만든 후, 이것을 절곡참숯부직포(10)가 미리 삽입되어 있는 금형(金型) 내의 성형공간(Cavity)으로 사출한다. 사출된 용융상태의 플라스틱은 금형 내 성형공간의 구석까지 흘러 들어가서 굳게 되는데 이 때에 절곡참숯부직포(10)는 플라스틱이 굳으면서 자동적으로 필터프레임(20)에 결합되게 된다. 그리고 나서 금형 속에서 필터프레임(20)을 꺼내게되면 필터프레임(20)과 절곡참숯부직포(10)가 일체로 된 자동차용 에어필터(1)가 완성된다. 여기서 필터프레임(20)과 절곡참숯부직포(10) 결합부위를 상세히 살펴보면, 필터프레임(20)의 길이방향의 상호 대향하는 두 모서리의 내측에 형성되는 돌출부(25)와, 필터프레임(20)의 길이방향의 가로로 상호 대향하는 두 모서리의 내측에 절곡참숯부직포(10)의 테두리부(11)가 소정 깊이만큼 삽입되어 플라스틱이 굳으면서 필터프레임(20)과 절곡참숯부직포(10)가 틈새 없이 별도의 결합부재없이 결합되게 된다.The filter frame 20 is manufactured by injection molding, and the plastics such as polypropylene are heated to a suitable temperature of about 200 ° C. to be melted, and then this is in a mold into which the bending charcoal nonwoven fabric 10 is inserted in advance. Injection into the cavity (cavity). The injected plastic in the molten state flows to the corner of the molding space in the mold and hardens. At this time, the bending charcoal nonwoven fabric 10 is automatically bonded to the filter frame 20 while the plastic is hardened. Then, when the filter frame 20 is taken out of the mold, the air filter 1 for the automobile in which the filter frame 20 and the bending charcoal nonwoven fabric 10 are integrated is completed. Looking at the coupling portion of the filter frame 20 and the bending charcoal nonwoven fabric 10 in detail, the projections 25 formed on the inner side of the two opposite sides of the filter frame 20 in the longitudinal direction, and the filter frame 20 The edge 11 of the bending charcoal nonwoven fabric 10 is inserted into the inner side of the two opposite sides in the longitudinal direction by a predetermined depth so that the filter frame 20 and the bending charcoal nonwoven fabric 10 are firmly formed while the plastic is hardened. It is combined without a separate coupling member.
손잡이(23)는 자동차의 공기유입구(31)에 에어필터를 탈착 또는 부착할 때에작업자가 손잡이(23)를 사용할 수 있도록 하여 에어필터의 탈, 부착을 편리하게 하는데, 본 실시 예에서는 손잡이(23)가 몸체(21)의 길이방향의 일측 단부에 하나 마련되어 있다. 그러나, 손잡이는 없을 수도 있으며 양측 단부에 모두 마련되도록 구성할 수도 있다.The handle 23 allows the operator to use the handle 23 when the air filter is attached or detached to the air inlet 31 of the vehicle, thereby making it easy to remove or attach the air filter.

At this time, the handle 23 can be pushed in, and it is convenient to use the handle 23 even when replacing. When the vehicle air filter 1 is installed, air in the atmosphere outside the vehicle is introduced through the external air intake 32 to pass through the vehicle air filter 1. At this time, pollen, dust or dust contained in the air is not filtered through the fine holes generated in the bending charcoal nonwoven fabric 10, so that only pure air passes. In addition, the antibacterial and deodorizing effect of the charcoal component of the bacteria that can inhabit the nonwoven fabric is suppressed and the smell is also removed. As such, the air passing through the air filter and in a sanitary and comfortable state flows into the vehicle through the indoor air intake 33 and is provided to the occupant.
이상과 같이, 참숯원료가 합성섬유와 초음파 융착되고 니들펀칭에 의해 제조된 참숯부직포를 약 150℃∼250℃의 온도에서 지그재그로 절곡시킨절곡참숯부직포(10)를, 고밀도수지의 사출성형에 의해 필터프레임(20)에 수용결합되도록 자동차용 에어필터(1)를 구성함으로써 자동차 외부의 대기 중에 포함된 다소 크기가 큰 먼지 또는 분진뿐만 아니라 미세한 먼지 또는 분진을 포집할 수 있으며 에어필터에 이차적으로 서식할 수 있는 각종 세균의 증식을 억제하고 냄새를 제거할 수 있게 된다.As described above, the bending charcoal nonwoven fabric 10 in which the charcoal raw material is ultrasonically fused with synthetic fibers and manufactured by needle punching is bent in a zigzag at a temperature of about 150 ° C to 250 ° C, by injection molding of high density resin. By configuring the air filter 1 for the vehicle to be received and coupled to the filter frame 20, it is possible to collect not only the larger dust or dust contained in the atmosphere outside the vehicle but also fine dust or dust, and to form secondary to the air filter. It is possible to suppress the growth of various bacteria that can be removed odor.
그리고, 필터프레임(20)의 몸체(21)에 손잡이(23)를 설치함으로써 자동차용 에어필터(1)의 탈착 및 부착을 편리하게 할 수 있도록 한다.And, by installing the handle 23 to the body 21 of the filter frame 20 to facilitate the removal and attachment of the air filter 1 for the vehicle.
전술한 실시 예에서는, 참숯부직포가, 합성고분자 접착제 1∼6wt%와, 참숯원료 10∼25wt%와, 합성섬유 69∼89wt%로 구성되는 것에 대하여 상술하였으나, 이는 에어필터의 절곡참숯부직포가 참숯원료에 의하여 검게 보이는 경우에 소비자에게 오래 된 에어필터로 오해받을 수 있는 문제점과 참숯원료가 공기정화 기능에 필요한 정량, 그리고 참숯원료의 합성섬유에 접착정도 등을 고려한 것이므로 적절한 용도에 따라서는 그 범위를 변경할 수 있음은 당연하다.In the above-described embodiment, the charcoal nonwoven fabric is composed of 1 to 6 wt% of synthetic polymer adhesive, 10 to 25 wt% of charcoal raw material, and 69 to 89 wt% of synthetic fiber, but this is the bending charcoal nonwoven fabric of the air filter. If the material appears to be black, the problem may be misunderstood by consumers as an old air filter, the amount of charcoal raw material needed for the air purification function, and the degree of adhesion to the synthetic fiber of the charcoal raw material. Of course you can change it.
또한, 전술한 실시 예에서는 절곡참숯부직포가 약 150℃∼200℃의 온도로 가열되면서 지그재그로 절곡된 것에 대하여 상술하였으나, 이는 상온의 경우에는 절곡이 어렵고 고온의 경우에는 절곡참숯부직포가 용융되는 문제점을 고려한 것이므로 이러한 문제점이 해결될 수 있다면 적절한 온도를 선택하여 절곡할 수 있음은 물론이다.In addition, in the above-described embodiment, the bending charcoal nonwoven fabric was bent in a zigzag while being heated to a temperature of about 150 ° C. to 200 ° C., but it is difficult to bend at room temperature and the bending charcoal nonwoven fabric is melted at high temperature. Since this problem can be solved, it is a matter of course that a suitable temperature can be selected and bent.
