이하, 본 고안의 바람직한 실시예를 첨부도면에 의거 상세히 설명하기로 한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 2는 본 고안에 따른 배출팬의 사시도이고, 도 3은 본 고안에 따른 배출팬의 작용상태 단면도로서, 그 구성상태를 살펴보면;Figure 2 is a perspective view of the discharge fan according to the present invention, Figure 3 is a cross-sectional view of the working state of the discharge fan according to the present invention, looking at its configuration;
유입공(21)이 형성되는 상판(2)과, 요입부(31)로 축결합구(311)가 형성되는 하판(3)의 사이로 다수개의 깃(4)이 형성되며, 상기 하판(3)의 요입부(31) 외둘레로는 보조배출날개(312)가 구성된다.A plurality of feathers 4 are formed between the upper plate 2 on which the inlet hole 21 is formed, and the lower plate 3 on which the axial coupling hole 311 is formed by the concave portion 31, and the lower plate 3. The outer periphery of the concave inlet portion 31 is the secondary discharge wing 312 is configured.
여기서, 본고안에 따른 배출팬(1)은 도 2에서와 같이 종래의 배출팬 구조와 같이 상판(2)으로 개방공인 유입공(21)이 형성되고, 하판(3)의 중앙으로 형성되는 요입부(31)로는 축결합구(311)가 설치되며, 이러한 상,하판(2,3)의 사이로 다수개의 깃(4)이 형성되는 구조를 갖는 것인데,Here, the discharge fan 1 according to the present invention is formed in the inlet hole 21 which is an opening hole to the upper plate 2 as in the conventional discharge fan structure, as shown in Figure 2, the center of the lower plate 3 As the 31, the shaft coupling sphere 311 is provided, and has a structure in which a plurality of feathers (4) are formed between the upper and lower plates (2, 3),
이와같은 하판(3)에 있어, 요입부(31)의 외둘레면으로는 다수개의 보조배출날개(312)를 일체로서 구성함을 특징으로 한다.In the lower plate 3 as described above, a plurality of auxiliary discharge wings 312 are integrally formed on the outer circumferential surface of the concave inlet portion 31.
이때, 상기 보조배출날개(312)는 다수개 깃(4)과 동일한 배출방향을 갖게 되며, 용접 또는 리벳팅 등에 의한 결합방식에 의해 하판(3)에 수직구조로서 일체화구성되는 것인데, 이러한 보조배출날개(312)가 갖는 높이를 설정함에 있어서는 배출팬(1)을 케이스(5)에 설치할 경우 하판(3)과 케이스(5)의 내부면사이로 형성되는 설치간격(H)의 폭을 고려함이 바람직하다.At this time, the auxiliary discharge wing 312 is to have the same discharge direction as the plurality of the feather (4), it is integrally configured as a vertical structure on the lower plate 3 by a coupling method by welding or riveting, such secondary discharge In setting the height of the wing 312, when installing the discharge fan 1 in the case 5, it is preferable to consider the width of the installation interval (H) formed between the lower plate 3 and the inner surface of the case (5). Do.
이에, 상기와 같은 구성을 갖는 본 고안에 따른 배출관(1)은 도 3에서와 같이 배출구(51)를 갖는 원통형체 케이스(5)에 내설되는 것인데, 이와같은 케이스(5)의 상부로는 배출로인 배출관(D)이 밀폐구조로서 연결되고, 케이스(5)의 하부로는 구동모터(52)가 상기 배출팬(1)과 동력연결되며 결합되는 것이다.Thus, the discharge pipe (1) according to the present invention having the configuration as described above is to be built in the cylindrical body (5) having a discharge port 51, as shown in Figure 3, the discharge to the upper portion of such a case (5) Roin discharge pipe (D) is connected as a closed structure, the lower portion of the case 5 is the drive motor 52 is coupled to the power supply and the discharge fan (1).
이러한, 배출팬(1)의 축결합구(311)와 구동모터(52) 동력축의 동력연결시, 마찰을 방지하기 위해 형성되는 설치간격(H)사이로 상기한 보조배출날개(312)가 위치하게 된다.When the shaft coupling port 311 of the discharge fan 1 and the driving motor 52 power shaft are connected to each other, the auxiliary discharge blade 312 is positioned between the installation intervals H formed to prevent friction. do.
따라서, 설치간격(H)사이로 보조배출날개(312)가 위치되는 본 고안의 배출팬(1)은 도 3에서와 같이 구동모터(52)의 동력을 전달받아 고속 회전하게 되면, 다수개의 깃(4)에 의해 기체를 배출구(51)로 강제배출함과 동시에 설치간격(H)사이로 위치되는 보조날개(312)또한 배출작용을 행함에 따라 설치간격에서 발생되었던 맴돌이현상을 방지할 수 있어 원활한 배출이 이루어지게 된다.Therefore, the discharge fan 1 of the present invention in which the auxiliary discharge wing 312 is positioned between the installation intervals H is rotated at a high speed by receiving the power of the driving motor 52, as shown in FIG. 4) by forcibly discharging the gas to the discharge port 51 by the auxiliary wing (312) located between the installation interval (H) at the same time can also prevent the eddy phenomenon generated in the installation interval by performing the discharge action smooth discharge This is done.
이와같은 본 고안의 배출팬(1)은 새롭게 제작되는 배출팬은 물론 기존에 사용하던 배출팬의 하판으로 보조배출날개를 형성하므로서 상기한 맴돌이현상을 방지할 수 있는 것이다.The discharge fan 1 of the present invention is to prevent the above eddy phenomenon by forming the auxiliary discharge wing as the lower plate of the discharge fan used as well as the discharge fan that is newly manufactured.
이상과 같이 본고안에 따른 배출팬은 케이스와의 설치간격사이로 보조배출날개를 형성하여 다수개 깃과 함께 보조배출날개또한 배출작용을 병행토록하므로서 설치간격에서 발생되었던 맴돌이 현상을 방지함에 따라 배출효율을 증대할 수 있는 효과를 갖는 것이다.As described above, the discharge fan according to the present invention forms the auxiliary discharge wing between the installation intervals with the case so that the auxiliary discharge wing together with the plurality of feathers also discharges, thereby preventing the eddy phenomenon generated at the installation interval, thereby improving the discharge efficiency. It will have the effect of increasing.
