발명의 분야Field of invention

본 발명은 에어필터에 관한 것이다. 보다 구체적으로, 본 발명은 자동차, 에어컨 등에 사용되는 에어필터에 관한 것으로 상하의 합성섬유 부직포층 사이에 구리섬유 부직포를 삽입, 적층시켜 공기의 정화기능은 물론 살균, 항균, 항취, 탈취 기능을 향상시킨 에어필터에 관한 것이다.The present invention relates to an air filter. More specifically, the present invention relates to an air filter used in automobiles, air conditioners, and the like, by inserting and laminating a copper fiber nonwoven fabric between upper and lower synthetic fiber nonwoven layers to improve air purification as well as sterilization, antibacterial, deodorization, and deodorization functions. It relates to an air filter.

발명의 배경Background of the Invention

에어필터는 자동차, 에어컨 등에는 필수적으로 사용되는 부품으로, 일정기간 사용 후 교체해야 하는 소모성 부품이다. 에어필터는 공기 내에 함유된 균류, 불순물 등을 제거하여 쾌적하고 위생적인 공기를 공급하기 위하여 매우 중요한 부품이라 할 수 있다. 예를 들어, 자동차의 연료 에어필터는 연료의 연소효율을 높이기 위하여 공기 내에 함유된 불순물을 정화하기 위하여 사용되고, 자동차의 에어컨에 사용되는 에어필터는 에어컨에서 나오는 시원한 바람을 여과하여 차안으로 공급하는 역할을 한다. 자동차뿐만 아니라 사무실이나 일반 가정에 설치하는 에어컨에 사용되는 에어필터도 상기와 같은 역할을 하게 된다.The air filter is an essential component for automobiles, air conditioners, etc., and is a consumable part that needs to be replaced after a certain period of time. Air filter is a very important part to supply pleasant and sanitary air by removing fungus, impurities, etc. contained in the air. For example, a fuel air filter of an automobile is used to purify impurities contained in the air in order to increase the combustion efficiency of the fuel, and an air filter used in an air conditioner of the vehicle filters the cool wind from the air conditioner and supplies it into the vehicle. Do it. Air filters used in air conditioners installed in offices or homes as well as cars will play the same role.

이제까지 에어필터는 여과 및 정화 기능을 원활히 수행하기 위하여 폴리에스터 부직포를 이용한 필터가 주로 사용되어 왔다. 폴리에스터 부직포는 폴리에스터 단섬유로 이루어진 부직포로서 양호한 공기의 여과 및 정화기능을 갖고 있다. 그러나, 에어필터에는 상기한 단순한 공기의 여과 및 정화기능 외에 항균이나 항취 기능도 요구되며, 그 결과 개발되어 사용되고 있는 것이 카본필터이다. 카본필터는 카본의 탈습, 항균 기능을 이용하여 폴리에스터 부직포 내에 카본 입자를 함유시켜 제조된 필터이다.Until now, the filter using a polyester nonwoven fabric has been mainly used in order to perform the filtration and purification functions smoothly. The polyester nonwoven fabric is a nonwoven fabric made of polyester short fibers and has a good air filtration and purification function. However, in addition to the simple filtration and purification functions of the air described above, the air filter also requires antibacterial and deodorizing functions, and as a result, carbon filters are being developed and used. The carbon filter is a filter manufactured by containing carbon particles in a polyester nonwoven fabric using dehumidification and antibacterial functions of carbon.

그러나, 카본필터도 살균이나 항균 기능이 우수하지 못하고, 탈취나 항취 기능도 뛰어난 효과를 나타내지 못하였다. 또한, 카본필터를 에어컨에 사용하는 경우에는 일정기간이 경과하면, 먼지가 많이 발생하는 결점이 있다. 특히 에어컨을 켤 때 에어필터에 부착되어 있던 먼지나 분해된 탄소입자가 밖으로 나오면서 심각한 먼지를 발생시킨다.However, the carbon filter also does not have excellent sterilization or antibacterial function, and did not show an excellent effect on deodorization or anti-odor. In addition, when a carbon filter is used in an air conditioner, there is a drawback that a lot of dust is generated after a certain period of time. Especially when the air conditioner is turned on, the dust attached to the air filter or the decomposed carbon particles come out, causing serious dust.

따라서, 본 발명자는 종래의 폴리에스터 부직포 필터나 카본필터가 갖는 상기와 같은 결점을 해결하기 위하여, 일반적으로 살균, 항균, 항취, 탈취 기능이 탁월한 구리를 에어필터에 적용하는 연구를 하게 되었고, 그 결과 상기 기능이 우수하고, 특히 장기간 사용하여도 먼지가 발생하지 않는 에어필터를 개발하기에 이른 것이다.Therefore, in order to solve the above drawbacks of the conventional polyester nonwoven fabric filter or carbon filter, the present inventors have been studied to apply copper to an air filter having excellent sterilization, antibacterial, deodorizing, and deodorizing functions. As a result, it is excellent to develop the air filter, which does not generate dust even after long-term use.

본 발명의 목적은 공기의 여과 및 정화기능은 물론 살균, 항균, 항취, 탈취 기능이 우수한 에어필터를 제공하기 위한 것이다.An object of the present invention is to provide an air filter excellent in sterilization, antibacterial, deodorant, deodorizing function as well as filtration and purification of air.

본 발명의 다른 목적은 장기간 사용하더라도 먼지를 발생시키지 않으며, 특히 에어컨을 켜는 순간에도 먼지를 발생시키지 않는 에어필터를 제공하기 위한 것이다.Another object of the present invention is to provide an air filter that does not generate dust even when used for a long time, and in particular, does not generate dust even when the air conditioner is turned on.

본 발명의 또 다른 목적은 자동차의 에어필터, 각종 에어콘의 에어필터, 및 각종 산업용 설비의 에어필터에 적용할 수 있는 여과 및 정화기능은 물론 살균, 항균, 항취, 탈취 기능이 우수하고, 전자파 차단효과가 있으며, 장기간 사용하더라도 먼지를 발생시키지 않는 에어필터를 제공하기 위한 것이다.Another object of the present invention is excellent in sterilization, antibacterial, deodorant, deodorizing function as well as filtration and purification functions that can be applied to air filters of automobiles, air filters of various air conditioners, and air filters of various industrial facilities, and electromagnetic shielding It is effective to provide an air filter that does not generate dust even after long-term use.
