엘리베이터용 공기청정기Air purifier for elevator
본 발명은 엘리베이터용 공기청정기에 관한 것으로, 구체적으로는 필터를 살균하기 위한 UV LED들이 움직이도록 구성된 엘리베이터용 공기청정기에 관한 것이다.The present invention relates to an elevator air purifier, and more particularly, to an elevator air purifier configured to move UV LEDs for sterilizing a filter.
엘리베이터 케이지에 신선하고 깨끗한 공기를 유입시키기 위해, 케이지의 천정에 공기청정기를 설치하는 경우가 많다. In order to introduce fresh and clean air into the elevator cage, an air purifier is often installed on the ceiling of the cage.
도 1A는 공기청정기가 설치된 엘리베이터 케이지의 내부를 보여주는 사시도이고, 도 1B는 공기청정기의 구조를 보여주는 도 1A의 1B-1B선 단면도이다.1A is a perspective view showing the inside of an elevator cage in which an air purifier is installed, and FIG. 1B is a cross-sectional view taken along line 1B-1B of FIG. 1A showing the structure of the air purifier.
도 1A에 도시된 바와 같이, 케이지의 천정 양쪽에 공기청정기(1)가 설치된다. 물론, 필요에 따라 다른 곳에 공기청정기가 설치될 수도 있다. As shown in Fig. 1A, the air purifier 1 is installed on both sides of the ceiling of the cage. Of course, the air purifier may be installed in another place if necessary.
도 1B는 도 1A의 1B-1B선 단면도로서, 종래의 공기청정기(1)의 구조를 자세히 보여준다. 도시된 바와 같이, 공기청정기(1)의 틀을 형성하고 판재로 이루어진 본체부(20) 안에 필터(30)가 설치되고, 필터(30)의 하부에 송풍팬(10)이 위치한다. 필터를 살균하기 위한 다수의 UV LED(45)를 갖추고 있는 브라켓(40)이 필터(30)의 상부이면서 본체부(20) 내부에 설치된다. 브라켓(40) 상부에는 본체부(20)를 덮는 커버(50)가 설치되는데, 일반적으로, 필터(30)에 공급되는 공기로부터 미세먼지나 불순물 등을 1차로 걸러내기 위한 프리필터(52)나, 공기중의 세균이나 박테리아 등을 1차로 살균하기 위한 광촉매(54)가 커버(50)에 설치되는 것이 일반적이다. 물론, 경우에 따라서는 이런 프리필터나 광촉매가 없을 수도 있다. 1B is a cross-sectional view taken along line 1B-1B of FIG. 1A, showing the structure of the conventional air purifier 1 in detail. As shown, the frame of the air purifier 1 is formed and the filter 30 is installed in the main body 20 made of a plate, and the blowing fan 10 is located under the filter 30 . A bracket 40 equipped with a plurality of UV LEDs 45 for sterilizing the filter is installed on the top of the filter 30 and inside the main body 20 . A cover 50 for covering the main body 20 is installed on the upper portion of the bracket 40, in general, a pre-filter 52 or , a photocatalyst 54 for primary sterilization of bacteria or bacteria in the air is generally installed in the cover 50 . Of course, there may be no such pre-filter or photocatalyst in some cases.
이와 같이 구성된 공기청정기(1)를 통과한 공기는 화살표(A) 방향으로 필터(30)를 통과해 엘리베이터 케이지 내부로 공급된다. 이때, 브라켓(40)에 설치된 UV LED(45)가 필터를 향해 자외선을 조사하면서 통과하는 공기는 물론 필터 표면을 살균한다.The air that has passed through the air purifier 1 configured in this way passes through the filter 30 in the direction of the arrow A and is supplied into the elevator cage. At this time, the UV LED 45 installed in the bracket 40 sterilizes the filter surface as well as the air that passes while irradiating ultraviolet rays toward the filter.
일반적으로, UV LED(45) 여러개를 나란히 배열하여 필터 표면을 조사하지만, UV LED(45)에서 나오는 자외선이 필터를 조사할 수 없는 사각지대가 반드시 생길 수밖에 없다. 또, 필터(30) 자체도 지그재그 형태로 이루어져 홈을 형성하고 있어 홈 안쪽으로는 자외선이 도달하지 못하는 사각지대가 존재하게 된다. 또한, 시간이 지날수록 필터 표면과 필터 홈 내부에 먼지, 이물질, 세균, 박테리아 등이 축적되는데, 이런 사각지대가 존재하기 때문에 완전한 살균이 이루어지지 못하는 문제가 있다.In general, a plurality of UV LEDs 45 are arranged side by side to irradiate the filter surface, but there is inevitably a blind spot where ultraviolet rays emitted from the UV LED 45 cannot irradiate the filter. In addition, since the filter 30 itself is also formed in a zigzag shape to form a groove, there is a blind spot where ultraviolet rays cannot reach inside the groove. In addition, as time goes by, dust, foreign substances, bacteria, and the like accumulate on the filter surface and inside the filter groove, but there is a problem in that complete sterilization cannot be achieved because such a blind spot exists.
본 발명은 종래의 이와 같은 문제점을 감안하여 안출된 것으로, UV LED를 필터 위에서 필터 길이를 따라 움직이면서 자외선을 조사하도록 함으로써, 자외선이 조사되지 못하는 필터의 사각지대를 없애 필터에 대한 자외선 살균효과를 종래에 비해 획기적으로 개선하는 것을 목적으로 한다.The present invention has been devised in view of such a problem in the prior art, and by irradiating the UV LED while moving along the length of the filter on the filter, the blind spot of the filter that cannot be irradiated with UV light is eliminated to improve the UV sterilization effect on the filter in the prior art. It aims to significantly improve the

In the illustrated embodiment, the UV LEDs 45 are disposed in one row in the center while forming a certain interval, but are arranged in two rows by one row on each edge. It may be arranged, it may be arranged in two rows of both edges and three rows of one row in the center, etc., if necessary, it is installed in the bracket 40 while forming one or more rows to irradiate the ultraviolet rays toward the filter 30 .
브라켓(40)은 외부 동력원(60)에 연결되고, 이 동력원(60)은 동력원의 동작을 제어하는 컨트롤러(C)에 연결된다. 따라서, 컨트롤러(C)의 제어하에 동력원(60)에 의해 브라켓(40)이 원하는 속도로 움직일 수 있다. 필요하다면, 컨트롤러(C)를 통해 브라켓(40)이 원하는 시간에 작동하도록 할 수도 있다.The bracket 40 is connected to an external power source 60 , and the power source 60 is connected to a controller C that controls the operation of the power source. Accordingly, the bracket 40 can move at a desired speed by the power source 60 under the control of the controller C. If necessary, the bracket 40 may be operated at a desired time through the controller C.
도 2에 도시된 것처럼, 동력원(60)이 전기모터(62)와, 전기모터(62)의 회전축에 직간접적으로 연결된 나사봉(64)을 포함할 수 있다. 이 경우, 브라켓(40)이 나사봉(64)에, 구체적으로는 나사봉의 나사산에 맞물리도록 되어있어, 전기모터(62)가 회전하면 나사봉이 회전하면서 브라켓(40)이 움직일 수 있다.As shown in FIG. 2 , the power source 60 may include an electric motor 62 and a screw rod 64 directly or indirectly connected to a rotation shaft of the electric motor 62 . In this case, the bracket 40 is engaged with the screw rod 64, specifically, the screw thread of the screw rod, so that when the electric motor 62 rotates, the screw rod rotates and the bracket 40 can move.
도 3은 브라켓(40)이 움직이는 상태를 보여준다. 동력원(60)이 작동하면 화살표(B) 방향으로, 브라켓(40)이 움직여, 도면을 기준으로 좌우로 원하는 방향과 속도로 움직이기 때문에, 브라켓(40)에 설치된 UV LED(45)에서 나오는 자외선이 필터(30)를 사각지대 없이 조사할 수 있게 된다.3 shows a state in which the bracket 40 is moved. When the power source 60 operates, the bracket 40 moves in the direction of the arrow B, and moves in the desired direction and speed left and right based on the drawing, so ultraviolet rays emitted from the UV LED 45 installed in the bracket 40 This filter 30 can be irradiated without blind spots.
동력원(60)으로 전기모터를 예로 들어 설명했지만, 크랭크축 방식으로 브라켓(40)을 움직이는 동력원을 사용할 수도 있고, 브라켓(40)을 수평으로 움직일 수 있으면 어떤 동력원도 본 발명에 속한다고 보아야 할 것이다.Although the electric motor has been described as an example of the power source 60, a power source that moves the bracket 40 in a crankshaft manner may be used, and if the bracket 40 can be moved horizontally, any power source will be considered to belong to the present invention. .
도 4는 사각지대 없이 자외선을 조사하는 상태를 보여주는 도면으로, 도 4A는 브라켓(40)이 공기청정기의 안쪽으로 움직이는 상태를, 도 4B는 브라켓이 공기청정기의 바깥쪽으로 움직이는 상태를 각각 보여준다.4 is a view showing a state in which ultraviolet rays are irradiated without a blind spot. FIG. 4A shows a state in which the bracket 40 moves inward of the air purifier, and FIG. 4B shows a state in which the bracket 40 moves outward of the air purifier.
도 4A의 상태에서, UV LED(45)의 자외선이 미치지 못하는 순간적인 사각지대가 어두운 부분으로 표시되어 있고, 도 4B의 상태에서도 순간적인 사각지대가 어두운 부분으로 표시되어 있다. 그러나, 브라켓이 화살표 방향으로 움직이기 때문에, 이런 순간적인 사각지대가 완전히 없어지게 된다.In the state of FIG. 4A , the instantaneous blind spot to which the ultraviolet light of the UV LED 45 does not reach is indicated as a dark part, and even in the state of FIG. 4B , the instantaneous blind spot is indicated as a dark part. However, since the bracket moves in the direction of the arrow, this instantaneous blind spot is completely eliminated.
도 5는 동력원(60)의 다른 실시예를 보여주는 도면이다. 이 실시예에서는, 동력원(60)이 크랭크축 방식으로 구동되어, 크랭크축이 회전체와 브라켓(40)을 연결하여 브라켓(40)을 수평으로 왕복 이동시킨다.5 is a diagram showing another embodiment of the power source 60 . In this embodiment, the power source 60 is driven in a crankshaft manner, and the crankshaft connects the rotating body and the bracket 40 to horizontally reciprocate the bracket 40 .
