However, there was a problem in that it was difficult to keep the kitchen space fresh and clean because odors, heat, and polluted air still remained due to local exhaust.

최근에는 천장 공간 전체를 급기챔버와 배기챔버로 구획하여 동시적으로 급기와 배기가 이루어지는 환기 시스템이 알려져 있다. 그러나 급, 배기 시스템의 구조물이 복잡하고 시공이 불편하며 배기구조가 미흡하여 효과적인 배기작동을 기대하기 어렵고, 기다란 만곡판체가 천정에 고정되는 구조이기 때문에 천정판을 분리하여 세척하거나 소제할 수 없으며 시설비가 높게 되는 등의 문제점이 있었다.Recently, a ventilation system in which the entire ceiling space is divided into an air supply chamber and an exhaust chamber to simultaneously supply and exhaust air is known. However, the structure of the supply and exhaust system is complicated and inconvenient to construct, and it is difficult to expect effective exhaust operation due to the insufficient exhaust structure. There were problems, such as becoming high.

이러한, 배기를 위한 장치와 관련된 기술이 한국등록실용신안 제0344071호에 제안된 바 있다.A technology related to such a device for exhaust has been proposed in Korean Utility Model Registration No. 0344071.

그러나 특허문헌 1은 배기 면적을 향상시키기 위해서 배기덕트의 수를 늘려야 하므로 비경제적인 문제점이 있었다.However, Patent Document 1 has an uneconomical problem because it is necessary to increase the number of exhaust ducts in order to improve the exhaust area.

더욱이, 도면에는 도시하지 않았지만 개폐부(118) 각각을 모터에 의해 권취 또는 권출되게 구비 가능하며, 이 경우 컨트롤러에 의해 동시 또는 개별 구동이 가능하여 제1 흡입구(112) 및 배기구(116)를 전부 또는 일부 개폐가 자동으로 구현 가능하다.Moreover, although not shown in the drawings, each of the opening and closing parts 118 can be wound or unwound by a motor, and in this case, simultaneous or individual driving is possible by the controller, so that the first inlet 112 and the exhaust port 116 are all or Some opening and closing can be realized automatically.

배기구(116)는 오염물질이 포함된 공기를 외부로 배기하는 통로이다.The exhaust port 116 is a passage for exhausting air containing contaminants to the outside.

한편, 배기구(116)는 제1 흡입구(112) 대비 2배 이상 면적이 크게 형성되어 제1 흡입구(112)에 의해 흡입속도를 감속시키면서 제1 흡입구(112)와 제2 흡입구(114)에서 흡입되는 공기의 배기가 가능해진다.On the other hand, the exhaust port 116 has an area that is twice as large as that of the first inlet 112 and is sucked from the first inlet 112 and the second inlet 114 while decelerating the suction speed by the first inlet 112 . It is possible to exhaust the exhausted air.

더욱이, 배기구(116)에는 설치공간 천장에 설치된 급기덕트와 연결되도록 연결부(150)가 탈착된다. 이때, 연결부(150)는 하단이 배기구(116)와 대응되는 면적으로 형성되지만 상단은 양쪽에 경사 형성되어 경사면을 타고 배기 방향이 고속으로 안내된다.Furthermore, the connection part 150 is detachably connected to the air supply duct installed on the ceiling of the installation space to the exhaust port 116 . At this time, the lower end of the connection unit 150 is formed in an area corresponding to the exhaust port 116 , but the upper end is inclined on both sides so that the exhaust direction is guided at high speed along the inclined surface.

흡입팬(120)은 제1 흡입구(112) 안쪽에 설치되어 제1 흡입구(112)와 제2 흡입구(114)를 통해 공기를 흡입한다.The suction fan 120 is installed inside the first suction port 112 to suck air through the first suction port 112 and the second suction port 114 .

이와 같이, 본 발명에 의한 배기장치(100)는 전원 인가시 제1 모터(122)와 제2 모터(132)가 구동되면서 흡입팬(120)과 배기팬(130)이 회동된다.As described above, in the exhaust device 100 according to the present invention, the suction fan 120 and the exhaust fan 130 are rotated while the first motor 122 and the second motor 132 are driven when power is applied.

이때, 흡입팬(120)에 의해 제1 흡입구(112)와 제2 흡입구(114)를 통해 주방 등의 설치공간 내에서 조리할 때 발생되는 오염물질이 흡입되고, 흡입된 공기가 배기팬(130)에 의해 배기구(116)로 강제 배기되는 과정에서 압력이 발생되며, 이 압력에 의해 제2 흡입구(114)를 통한 주위 공기가 딸려 들어오면서 더해져 흡입면적이 커진다.At this time, pollutants generated during cooking in an installation space such as a kitchen are sucked by the suction fan 120 through the first suction port 112 and the second suction port 114 , and the sucked air is discharged by the exhaust fan 130 . ), pressure is generated in the process of being forcibly exhausted to the exhaust port 116, and the ambient air through the second suction port 114 is added by this pressure to increase the suction area.

이때, 흡입팬(120)에서 배기팬(130)으로 평행하는 바람을 만들어서 넓은 범위에서 오염물질을 흡입하고, 흡입팬(120)에 의해 밀어주는 바람과 배기팬(130)에 의한 배기하는 바람을 모두 흡입해서 밖으로 배출해야 하므로 배기팬(130)의 용량이 2배 이상 크다.At this time, the suction fan 120 creates a parallel wind to the exhaust fan 130 to suck in pollutants in a wide range, and the wind pushed by the suction fan 120 and the wind exhausted by the exhaust fan 130 are The capacity of the exhaust fan 130 is more than twice as large as all of them must be sucked in and discharged to the outside.

이렇게, 본 발명은 오염물질이 발생되는 범위는 넓은데 좁은 범위만 흡입이 되어 멀리 떨어진 위치의 오염물질은 흡입이 안되는 기존 문제점을 해결 가능하여 흡입팬(120)에서 바람을 밀어주고 배기팬(130)에서 흡입 및 배출하면서 근처에 있던 공기가 딸려 들어와 넓은 범위의 오염물질을 흡입하므로 흡입면적이 크다.In this way, the present invention can solve the existing problem that pollutants at a distant location cannot be sucked because only a narrow range is sucked although the range in which pollutants are generated is wide. ), the air that was nearby comes in and sucks in a wide range of pollutants, so the suction area is large.

이상 첨부된 도면을 참조하여 본 발명의 실시 예들을 설명하였지만, 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자는 본 발명이 그 기술적 사상이나 필수적인 특징을 변경하지 않고서 다른 구체적인 형태로 실시될 수 있다는 것을 이해할 수 있을 것이다. 그러므로 이상에서 기술한 실시예들은 모든 면에서 예시적인 것이며 한정적이 아닌 것으로 이해해야만 한다.Although embodiments of the present invention have been described above with reference to the accompanying drawings, those of ordinary skill in the art to which the present invention pertains can realize that the present invention may be embodied in other specific forms without changing its technical spirit or essential features. you will be able to understand Therefore, it should be understood that the embodiments described above are illustrative in all respects and not restrictive.
