Description
본 고안은 주로 지하 주차장이나 작업장의 내부에 설치하여서, 흡기팬으로 유입되는 외부의 신선한 공기를 실내에 신속히 확산시키는 역할을 하고, 또한 내부의 탁하고 오염된 공기는 배기팬 쪽으로 신속히 이동시켜서 외부로 원활히 배출되도록 하는 환풍기에 있어서, 공기의 흡입 및 배출량을 증진시켜서 환기효율을 높이고, 소음을 최소화하도록 된 고안에 관 것이다. 종래에도 이와 같은 목적의 환풍기가 사용되어 왔으나, 대개는 동체가 단순한 원동형으로 구성되고, 흡입구나 배출구의 내측에 흡음재인 유리섬유 등을 적치하는 정도여서, 오염된 공기가 오히려 흡음재에 누적되는 폐단이 있었고, 경우에 따라 오염된 공기를 배가하여 그대로 방출하기 때문에 쾌적한 공기를 보낼 수가 없어서 환기능력이 부족하였으며, 또한 소음이 많이 발생하는 문제점이 있었다. 따라서 환기량을 확대시키고, 소음을 대폭 감소하여서 정숙한 실내를 유지할 수가 있는 환풍기가 절실히 요구되었다.The present invention is mainly installed in the underground parking lot or workshop, and serves to quickly diffuse the fresh air from the intake fan into the room, and also to move the muddy and contaminated air to the exhaust fan quickly to smoothly to the outside. In the ventilator to be discharged, it is designed to increase the intake and discharge of air to increase the ventilation efficiency, and to minimize the noise. Conventionally, a ventilator for this purpose has been used, but the fuselage is usually composed of a simple cylindrical body, and the inside of the inlet or outlet is piled up with a glass fiber, which is a sound absorbing material, so that contaminated air accumulates in the sound absorbing material. In this case, in some cases, the polluted air is doubled and released as it is, so it is not possible to send comfortable air, and the ventilation capacity is insufficient, and there is a problem that a lot of noise is generated. Therefore, there is an urgent need for a ventilator capable of maintaining a quiet interior by enlarging the ventilation volume and drastically reducing the noise.
본 고안에서는 이러한 종래의 제반 문제점을 감안하여서 안출된 것으로서, 동체의 흡입구는 홉퍼형으로 구성되고, 배출구는 점차 협소하게 구성되어서 외부에 벤튜리관이 결합되었으며, 중앙에 설치된 팬에 인접하여 공기유도익이 축수대에 축 설치되었다. 그리고 팬과 공기유도익의 전후측에는 주벽에 흡음공이 무수히 천공된 흡음관이 횡으로 대향 설치되고, 각 흡음관의 외측에 위치한 동체에는 흡음공이 내벽에 무수히 천공된 흡음대가 감싸지게 설치되었다. 상기에서 각 흡음관과 흡음대에는 종래와 같이 흡음재인 유리섬유 등을 일체 사용하지 않으므로 공기가 오염되거나 또는 오염물이 누적될 염려가 전혀 없다. 이와 같이된 구성으로, 팬이 가동되면 홉퍼형 흡입구로 공기가 유입되는데, 이때 발생되는 소음은 흡입구측의 흡음관과 흡음대에 형성된 각 흡음공으로 분산 흡수되면서 순화시켜줌으로 현저하게 소음을 감소해 주게 되고, 팬의 흡입력에 연동되는 공기유도익에 의해 활발한 와류현상을 일으키면서 신속하고 원활히 이동되는 공기는 다시 배출구측의 흡음관과 흡음대에 의해 더욱 현저하게 소음이 감소된 상태로 배출된다. 이때 배출구가 점차 협소하게 형성되고, 벤튜리관이 결합되어서 벤튜리현상으로 공기의 유속을 증가시켜서 주위의 공기를 동시에 배기팬 방향으로 신속히 이동시키는 효과를 얻게 된다. 따라서 실내의 환기작용을 증대시켜서 항상 조용하고 쾌적한 환경을 유지시킬 수가 있다.In the present invention was devised in view of the above-mentioned conventional problems, the inlet of the fuselage of the fuselage, the outlet is gradually narrower, the venturi tube is coupled to the outside, the air induction is adjacent to the fan installed in the center The shaft was installed in the sink. In addition, the front and rear sides of the fan and the air induction vane are provided with sound absorbing tubes horizontally perforated in the main wall horizontally, and the sound absorbing holes in which the sound absorbing holes are perforated in the inner wall are enclosed in the fuselage located outside the respective sound absorbing tubes. In the sound absorbing tube and the sound absorbing band as described above, there is no fear that air is contaminated or contaminants accumulate because no glass fibers, etc., which are sound absorbing materials are used at all. In this configuration, when the fan is operated, air flows into the hopper type suction port, and the noise generated at this time is remarkably reduced by being absorbed and absorbed into each sound absorbing hole formed in the sound absorbing tube and the sound absorbing table on the suction side. In addition, the air moving quickly and smoothly while causing vigorous vortex phenomena by the air induction benefit that is linked to the suction force of the fan is discharged in a state in which the noise is more significantly reduced by the sound absorbing tube and the sound absorption band on the outlet side. At this time, the outlet is gradually narrowed, the venturi tube is coupled to increase the flow rate of the air in the venturi phenomenon to obtain the effect of moving the surrounding air in the direction of the exhaust fan at the same time. Therefore, by increasing the ventilation of the room can always maintain a quiet and comfortable environment.
