Here, the present invention is not limited to the embodiments disclosed below, but may be implemented in a variety of different forms, and only these embodiments allow the disclosure of the present invention to be complete, and are common in the technical field to which the present invention pertains. Since it is provided by way of example so that those with knowledge of the present invention can clearly understand the scope of the invention, the technical scope of the present invention should be defined by the claims.

아울러, 아래의 본 발명을 설명함에 있어서 공지 기능 또는 구성 등에 대한 구체적인 설명이 본 발명의 요지를 불필요하게 흐릴 수 있다고 판단되는 경우에는 그 상세한 설명을 생략할 것이다. 그리고, 후술되는 용어들은 본 발명에서의 기능을 고려하여 정의된 용어들인 것으로, 이는 사용자, 운용자 등의 의도 또는 관례 등에 따라 달라질 수 있음은 물론이다. 그러므로, 그 정의는 본 발명의 설명 전반에 걸쳐 기술되는 기술사상을 토대로 이루어져야 할 것이다.In addition, in the following description of the present invention, if it is determined that a detailed description of a well-known function or configuration may unnecessarily obscure the gist of the present invention, the detailed description thereof will be omitted. And, the terms to be described later are terms defined in consideration of functions in the present invention, which may vary depending on the intentions or customs of users, operators, etc., of course. Therefore, the definition should be made based on the technical idea described throughout the description of the present invention.

이하, 첨부된 도면을 참조하여 본 발명의 바람직한 실시예에 대하여 상세하게 설명한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1 내지 도 3은 본 발명의 제1실시예를 보인 사진 및 사용상태를 보인 사진들이다. 본 발명은 도 1에 게시된 바와 같이, 상하로 개방된 통체형상의 패브릭필터부(12)와, 패브릭필터부(12)의 상하단부에 구비된 탄성밴드부(14)를 포함한다.1 to 3 are pictures showing a first embodiment of the present invention and pictures showing a state of use. The present invention includes, as shown in FIG. 1 , a cylindrical fabric filter part 12 opened up and down, and an elastic band part 14 provided at the upper and lower ends of the fabric filter part 12 .

상기 패브릭필터부(12)는 통기성을 가지는 천(fabric)으로 이루어져서 상하로 개방된 통체형상을 가진다. 이러한 패브릭필터부(12)는 직물이나 편물 등으로 된 천을 사각형으로 절단하고, 좌우 양단부를 박음질하여 이루어진다. The fabric filter unit 12 is made of a breathable fabric (fabric) and has a cylindrical shape opened up and down. The fabric filter unit 12 is made by cutting a fabric made of fabric or knitted fabric into a square shape, and stitching the left and right ends.

패브릭필터부(12)가 통기성과 더불어 신축성을 가지는 천으로 이루어지면, 상기 탄성밴드부(14)와 함께 직경방향으로 신축되므로 후술하는 바와 같이, 공기청정기(2)에 씌우면, 공기청정기(2)에 밀착되므로 공기청정기에 씌워진 상태가 좀 더 견고하게 유지될 뿐만 아니라 공기청정기(2)에 씌워진 상태도 보기가 좋다.When the fabric filter part 12 is made of a fabric having elasticity as well as breathability, it expands and contracts together with the elastic band part 14 in the radial direction. Since it is closely attached, the state covered with the air purifier is maintained more firmly, and the state covered with the air purifier 2 is also good looking.

그리고 탄성밴드부(14)는 패브릭필터부(12)의 양단부에 박음질되어 연결되는데, 이러한 탄성밴드부(14)에 의해 본 발명이 공기청정기(2)에 씌워진 상태가 유지된다. 탄성밴드부(14)는 의류에 흔히 사용되는 고무밴드로 이루어진다.And the elastic band portion 14 is sewn to both ends of the fabric filter portion 12 and is connected, and the state in which the present invention is covered with the air purifier 2 is maintained by the elastic band portion 14 . The elastic band unit 14 is made of a rubber band commonly used for clothing.

이러한 구성을 가지는 본 발명은 도 2 및 도 3에 게시된 바와 같이, 상기 패브릭필터부(12)가 공기청정기(2)의 공기흡입공이 형성된 둘레면을 감싸도록 공기청정기(2)에 씌워서 사용된다. 도 2는 본 발명이 원통형상의 공기청정기에 사용된 것을 보인 사진이고, 도 3은 본 발명이 사각형상의 공기청전기에 사용된 것을 보인 사진이다. 바람직하게는 소비자들이 소유하고 있는 공기청정기와 맞는 규격의 제품을 구입하여 사용할 수 있도록 본 발명은 다양한 사이즈로 제작된다. The present invention having such a configuration is used by covering the air purifier 2 so that the fabric filter unit 12 surrounds the circumferential surface of the air purifier 2 on which the air intake holes are formed, as shown in FIGS. 2 and 3 . . 2 is a photograph showing that the present invention is used in a cylindrical air purifier, and FIG. 3 is a photograph showing the present invention is used in a rectangular air purifier. Preferably, the present invention is manufactured in various sizes so that consumers can purchase and use a product of a standard that matches the air purifier that they own.

이와 같이 본 발명을 공기청정기(2)에 씌우면 공기청정기(2)의 공기흡입공이 패브릭펄터부(12)에 의해 커버되므로 실내공기가 패브릭필터부(12)를 통과하여 공기청정기로 유입된다. 따라서 실내공기가 패브릭필터부(12)에 의해 비교적 입자가 큰 먼지가 1차적으로 제거되어 공기청정기로 유입된다. As described above, when the present invention is applied to the air purifier 2 , the air intake hole of the air purifier 2 is covered by the fabric filter unit 12 , so that indoor air passes through the fabric filter unit 12 and flows into the air purifier. Accordingly, in the indoor air, relatively large particles of dust are primarily removed by the fabric filter unit 12 and introduced into the air purifier.

본 발명은 천으로 이루어진 패브릭필터부(12)에 탄성밴드부(14)가 연결되어 이루어져서 세탁하여 재사용이 가능하므로, 본 발명이 오염되면 공기청정기에서 벗겨서 세탁한 후 재사용하면 된다. 따라서 본 발명은 관리가 용이라고 반복사용이 가능하므로 경제적이다In the present invention, since the elastic band part 14 is connected to the fabric filter part 12 made of cloth so that it can be washed and reused, if the present invention is contaminated, it can be removed from the air purifier and washed and reused. Therefore, the present invention is economical because it is easy to manage and can be used repeatedly.

특히, 전술한 바와 같이, 실내공기가 본 발명에 의해 1차적으로 필터링되어 공기청정기로 유입되므로 공기청정기 내부에 구비된 필터의 부하가 감소된다. 따라서 공기청정기 필터의 수명이 연장되어 공기청정기 필터의 교체주기가 길어지므로 공기청정기의 유지관리가 용이해지며, 공기청정기의 필터교체비용도 절감된다. In particular, as described above, since indoor air is primarily filtered by the present invention and introduced into the air purifier, the load on the filter provided inside the air purifier is reduced. Accordingly, the lifespan of the air purifier filter is extended and the replacement cycle of the air purifier filter is lengthened, so the maintenance of the air purifier becomes easy, and the filter replacement cost of the air purifier is also reduced.

이하에서는 본 발명의 다른 실시예를 설명하되, 전술한 실시예와 동일한 구성 및 효과에 대해서는 설명을 생략한다. Hereinafter, other embodiments of the present invention will be described, but descriptions of the same configurations and effects as those of the above-described embodiments will be omitted.

본 발명의 제2실시예에서는 상기 패브릭필터부(12)는 무기항균제가 함유된 이형단면의 합성섬유와 폴리우레탄섬유 탄성사로 직조된 천으로 이루어진다.In the second embodiment of the present invention, the fabric filter unit 12 is made of a synthetic fiber of a different cross-section containing an inorganic antibacterial agent and a cloth woven with a polyurethane fiber elastic yarn.

무기항균제가 함유된 이형단면의 합성섬유는 무기항균제에 의해 항균성을 가지며, 아울러 이형단면에 의해 흡한속건성을 가진다. 이형단면의 합성섬유가 단면특성으로 인해 흡한속건성을 가지는 것은 공지된 바이므로 이에 대한 상세한 설명은 생략한다. 또한, 흔히 무기항균제로는 나노 은이 사용되거나 또는 은, 아연, 구리 등이 치환된 제올라이트, 실리카겔, 인산칼슘 등이 사용되는데, 본 발명에서도 이러한 공지된 무기항균제가 사용된다. Synthetic fibers with a deformable cross section containing an inorganic antibacterial agent have antibacterial properties due to the inorganic antibacterial agent, and also have sweat perspiration and quick-drying due to the deformable cross section. Since it is known that synthetic fibers having a different cross-section have sweat-absorbing and quick-drying properties due to their cross-sectional characteristics, a detailed description thereof will be omitted. In addition, nano-silver is often used as the inorganic antibacterial agent, or zeolite substituted with silver, zinc, copper, etc., silica gel, calcium phosphate, etc. are used. These known inorganic antibacterial agents are also used in the present invention.

이와 같이 무기항균제가 함유된 이형단면의 합성섬유와 폴리우레탄섬유 탄성사로 직조된 천으로 패브릭필터부(12)가 형성되면 패브릭필터부(12)는 통기성, 신축성과 더불어 항균성, 흡한속건성을 가진다. 따라서 패브릭필터부(12)의 항균성에 의해 본 발명에 세균이 번식되는 것이 방지되는 것은 물론이고 실내공기가 항균처리되고, 실내공기의 습도에 의해 패브릭필터부(12)가 젖더라도 신속하게 건조되므로 본 발명을 좀 더 위생적으로 사용할 수 있게 된다. As described above, when the fabric filter unit 12 is formed of a cloth woven with a synthetic fiber and polyurethane fiber elastic yarn of a different cross-section containing an inorganic antibacterial agent, the fabric filter unit 12 has breathability and elasticity as well as antibacterial and sweat-absorbing and quick-drying properties. Therefore, the antibacterial properties of the fabric filter unit 12 prevent the propagation of bacteria in the present invention, as well as the antibacterial treatment of the indoor air, and the quick drying of the fabric filter unit 12 even if the fabric filter unit 12 gets wet due to the humidity of the indoor air. The present invention can be used more hygienically.

특히 바람직하게는 상기 패브릭필터부(12)는 무기항균제가 함유된 이형단면의 폴리에스테르 섬유와 폴리에스테르섬유 탄성사로 직조된 천으로 이루어진다. Particularly preferably, the fabric filter unit 12 is made of a polyester fiber of a different cross-section containing an inorganic antibacterial agent and a cloth woven with a polyester fiber elastic yarn.

일반적으로 폴리에스테르 섬유는 전기전도성과 소수성이 낮기 때문에 직조과정에서 발생되는 마찰 등에 의해 발생된 정전기가 방전되지 못하고 축적되는 정전기적 특성을 가지는데, 흔히, 폴리에스테르 섬유 생산시에 폴리에스테르 섬유 원료에 대전방지제를 첨가하여 폴리에스테르 섬유의 정적기적 특성을 소실시킨다. In general, since polyester fibers have low electrical conductivity and hydrophobicity, static electricity generated by friction generated during the weaving process is not discharged and has an electrostatic property that is accumulated. Antistatic agents are added to lose the static and mechanical properties of polyester fibers.

그러나 본 발명에서는 폴리에스테르 섬유의 정전기적 특성을 이용하여 패브릭필터의 먼지포집력, 즉, 필터성능을 향상시키기 위해 대전방지제가 함유되지 않은 폴리에스테르 이형단면사와 폴리우레탄 탄성사로 직조된 천으로 패브릭필터부(12)를 형성시켜서, 패브릭필터부(12)가 폴리에스테르 섬유의 정적기적 특성에 의해 좀 더 우수한 필터성능을 가지도록 한다.However, in the present invention, using the electrostatic properties of the polyester fiber to improve the dust collecting power of the fabric filter, that is, the filter performance, the fabric filter is a fabric filter woven with a polyester non-static cross-section yarn and a polyurethane elastic yarn that does not contain an antistatic agent. By forming the part 12, the fabric filter part 12 has better filter performance due to the static and mechanical properties of the polyester fiber.

이상의 설명은 본 발명의 기술사상을 예시적으로 설명한 것에 불과한 것으로서, 본 발명이 속하는 기술 분야에서 통상의 지식을 가진 자라면 본 발명의 본질적인 특성에서 벗어나지 않는 범위 내에서 여러 가지 치환, 변형 및 변경 등이 가능함을 쉽게 알 수 있을 것이다. 즉, 본 발명에 개시된 실시 예들은 본 발명의 기술 사상을 한정하기 위한 것이 아니라 설명하기 위한 것으로서, 이러한 실시 예에 의하여 본 발명의 기술 사상의 범위가 한정되는 것은 아니다.The above description is merely illustrative of the technical idea of the present invention, and those of ordinary skill in the art to which the present invention pertains may make various substitutions, modifications, and changes within the scope not departing from the essential characteristics of the present invention.
