Zusammenfassung: | The present invention relates to a natural ventilation device that increases the amount of ventilation. More specifically, the present invention comprises: a main body having an air flow passage between an upper body and a lower body spaced at a predetermined distance in a vertical direction; end caps installed on both ends of the main body; a flap rotatably installed on the end cap to open and close the air flow passage; and a filter cover, where a fine dust filter corrugated in a zigzag shape is installed at a rear side of the ventilation hole, installed on a front side of the main body and having a plurality of ventilation holes. The present invention filters a larger amount of external air per each unit time and supplies the filtered air to an indoor space to increase the amount of ventilation.
본 발명은 환기량이 증대되는 자연환기장치에 관한 것으로서, 특히 상하방향으로 일정거리 이격된 상부바디와 하부바디 사이에 공기유로가 형성된 본체와; 상기 본체의 양측단에 설치되는 엔드캡과; 상기 엔드캡에 회전가능하게 설치되어 상기 공기유로를 개폐하는 플랩과; 상기 본체의 전면에 설치되고, 다수의 통기홀이 형성되며, 지그재그 형태로 주름진 미세먼지 필터가 상기 통기홀의 후방에 설치된 필터커버;를 포함하여 구성되어, 단위 시간 당 더 많은 양의 외부공기를 필터링한 후 실내로 공급하여 환기량을 증가시킬 수 있는 효과가 있다. |
