본 발명에 따르면, 송풍팬을 지지하기 위한 팬하우징과 환풍구 사이에 환형공간이 마련되게 되며, 송풍팬을 가동할 경우에, 팬하우징의 내부공간 뿐만 아니라 그의 외부공간이 되는 환형공간을 통해서도 유체가 유입된다. 이에 의하면 팬하우징을 통과한 유체는 저항 없이 환풍구를 빠져나가게 되고 그 주변에 있는 유체는 베르누이 원리에 의해 환풍구로 유입되게 된다. 결국 같은 용량의 송풍팬을 이용하여 더 많은 유량을 환풍구를 통해 송풍할 수 있게 되는 것이다. 본 발명에 의한 유도관은 유체의 직진성 향상에 기여함으로써 많은 유량이 신속히 환풍구를 통과할 수 있도록 유도한다.

As a result, a larger amount of air can be blown through the ventilation holes by using a blowing fan of the same capacity. INDUSTRIAL APPLICABILITY The induction pipe according to the present invention contributes to the improvement of the straightness of the fluid, thereby guiding a large amount of flow to quickly pass through the ventilator.

이하, 첨부된 도면을 참조하여 본 발명의 구체적인 내용을 상세하게 설명한다. 우선 도 1 내지 도 3을 참조하여 기본적 사항을 설명하겠으며, 나머지 도면은 필요한 곳에서 인용하면서 설명한다. 그리고 본 발명의 방법적 내용에 대하여 먼저 설명하겠으며, 이후 이 방법이 토대를 이루고 있는 송풍장치를 설명하기로 한다. Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. First, basic matters will be described with reference to Figs. 1 to 3, and the remaining drawings will be described while citing them where necessary. The method of the present invention will be described first, and then the blowing apparatus on which the method is based will be described.
본 발명이 방법으로 해석될 수 있는 이유는 기성의 송풍팬을 본 발명의 기술적 사상에 부합되도록 각종 장치 또는 시설에 설치함으로써 향상된 효과를 얻을 수 있기 때문이다. The reason why the present invention can be interpreted by the method is that an improved effect can be obtained by installing a conventional blowing fan in various devices or facilities in accordance with the technical idea of the present invention.
본 발명은 송풍팬을 기본으로 포함하는 것으로 설명되고 있지만, 액체에도 적용될 수 있는 것이므로 프로펠러가 될 수도 있다. 이하의 설명은 유체를 대표하여 기체를 대상으로 하여 이루어진다. Although the present invention has been described as basically including a blowing fan, it can be applied to a liquid, and thus can be a propeller. The following description is made on a gas as a representative of a fluid.
본 발명의 방법은 공간을 구획하는 일측 공간의 유체를 타측 공간으로 보내기 위한 송풍팬(10)을 환풍구(H)에 설치하는 방법에 관한 것이다. 환풍구(H)는 각종 벽체(W)에 마련된다. The method of the present invention relates to a method for installing a blowing fan (10) in a ventilation hole (H) for sending a fluid in one space dividing a space to the other space. The ventilation holes H are provided in various kinds of walls W.
송풍팬(10)은 모터본체(13), 모터본체(13)의 회전축에 결합되는 회전날개(12)를 포함한다. 회전날개(12)의 형태는 다양할 수 있으나 축류식 송풍기에 사용되는 형식의 것이 적합하다. 그리고 송풍팬(10) 주위로 유체가 통과될 수 있도록 송풍팬(10)은 송풍팬 설치수단(20)에 의해 벽체(W)에 고정 설치된다. The blowing fan 10 includes a motor body 13 and a rotary vane 12 coupled to a rotary shaft of the motor body 13. The shape of the rotary vane 12 may vary, but a type suitable for an axial flow blower is suitable. The blowing fan 10 is fixed to the wall W by the blowing fan mounting means 20 so that the fluid can pass around the blowing fan 10.
송풍팬(10)은 팬지지대(23)를 통해 팬하우징(21)의 중심부에 지지된다. 본 발명에 의하면 팬하우징(21)을 벽체(W)의 전면으로부터 소정의 간격(G)으로 이격되도록 고정하는 단계를 포함한다. 그리고 이의 사전 단계로서, 팬하우징(21)의 직경(D1)이 환풍구(H)의 직경(D2)과 같거나 그보다 작게 되도록 선택하는 단계가 있다. 물론 회전날개(12)의 직경 역시 환풍구(H)의 직경보다 작게 되어 있다. The blowing fan 10 is supported at the center of the fan housing 21 through the fan support 23. According to the present invention, the step of fixing the fan housing 21 is spaced apart from the front surface of the wall W by a predetermined gap G. As a preliminary step, there is a step of selecting the diameter D1 of the fan housing 21 to be equal to or smaller than the diameter D2 of the vent hole H. Of course, the diameter of the rotary vane 12 is also smaller than the diameter of the ventilation hole H.
그리고 팬하우징(21)이 벽체(W)의 전면으로부터 이격되는 간격(G)은 환풍구(H)의 직경 내지 송풍팬(10)의 규격에 따라 달라질 수 있으나, 일반적인 환풍기를 예로 들면 10 ~ 150mm가 될 수 있다. The gap G between the fan housing 21 and the front surface of the wall W may vary according to the diameter of the ventilation hole H or the size of the ventilation fan 10. For example, .
위와 같은 방법에 의하면, 송풍팬(10)이 가동할 때 베르누이의 원리에 의해 유체가 팬하우징(21)의 측부공간을 통해서도 환풍구(H)로 빨려 들어가게 된다(F3 참조). 즉 그만큼 유체의 유입량(또는 송풍량)이 많아지게 되는 것이다. 작용과 관련한 상세한 내용은 후술하기로 한다. According to the above-described method, the fluid is sucked into the vent hole H through the side space of the fan housing 21 by the Bernoulli's principle when the blowing fan 10 is operated (see F3). That is, the inflow amount (or the blowing amount) of the fluid increases accordingly. Details of the operation will be described later.
본 발명의 또 다른 실시예에 의하면, 벽체(W)의 후면에 송풍 방향을 따라 직경이 감소되는 관형상의 제1유도관(30, main guide tube)을 설치하는 단계가 추가된다. According to another embodiment of the present invention, a step of installing a tubular main guide tube (30) whose diameter is reduced along the blowing direction is provided on the rear surface of the wall body (W).
이 제1유도관(30)은 유체의 직진성 향상을 위한 것으로서, 벽체(W)의 환풍구(H)를 통과한 유체가 즉시로 확산되지 않고 어느 정도까지 운동에너지를 갖고 유동할 수 있도록 안내하는 것이다. 이 운동에너지는 제1유도관(30)과 벽체(W) 사이의 공간을 통해 외부공기가 부압에 의해 제1유도관(30)으로 유입(F5 참조)되도록 하는 작용을 한다. The first induction pipe 30 is for improving the straightness of the fluid and guides the fluid that has passed through the ventilation hole H of the wall W to flow with kinetic energy to some extent without being immediately diffused . This kinetic energy acts to allow the outside air to flow into the first induction pipe 30 (see F5) through the space between the first induction pipe 30 and the wall W by the negative pressure.
제1유도관(30)은 길이방향을 따라 단면적이 일정한 원통형태로 되어 있을 수도 있고, 단면적이 점차로 작아지는 깔때기 형상으로 되어 있을 수도 있다. 제1유도관(30)은 벽체(W)에 밀착 설치될 수도 있고 이격되게끔 설치될 수도 있다. The first induction pipe 30 may have a cylindrical shape with a constant cross-sectional area along the longitudinal direction, or may have a funnel shape with a gradually smaller cross-sectional area. The first induction pipe 30 may be installed closely to the wall W or may be spaced apart.
제1유도관(30)의 외측에는 그와 동일한 축중심을 갖도록 제2유도관(40)을 더 설치할 수 있다(도 4 참조). 제2유도관(40)은 소정의 브래킷을 통해 제1유도관(30)에 연결될 수 있으며, 제2유도관(40)은 벽체(W)에 지지될 수 있다. A second induction pipe 40 may be further provided on the outer side of the first induction pipe 30 so as to have the same axial center (see FIG. 4). The second induction pipe 40 can be connected to the first induction pipe 30 through a predetermined bracket and the second induction pipe 40 can be supported on the wall W. [
이하에서는 위의 방법을 구현하기 위한 송풍장치를 도 1 내지 도 6을 참조하여 설명한다. Hereinafter, a blowing apparatus for implementing the above method will be described with reference to Figs. 1 to 6. Fig.
본 발명의 송풍장치는 벽체(W)에 마련되는 환풍구(H)의 입구측에 설치되어 일측 공간의 유체를 타측 공간으로 보내기 위한 것이며, 위에 설명된 방법발명에 의거하여 작용한다. The ventilating apparatus of the present invention is provided on the inlet side of the ventilation hole H provided in the wall W and is intended to send the fluid in one space to the other space and operates in accordance with the method described above.
송풍팬(10)은 모터본체(13), 모터본체(13)의 회전축에 결합되는 회전날개(12)를 포함한다. 회전날개(12)는 보스(11)를 통해 모터본체(13)에 결합된다. 송풍팬(10)은 원통형 팬하우징(21)의 내부 중심에 설치된다. 송풍팬(10)은 팬지지대(23)에 의해 팬하우징(21)의 중심에 고정 지지된다. 송풍팬(10)의 기동에 의해 팬하우징(21)의 전방에 있는 유체가 팬하우징(21)을 통과하여 후방으로 공급된다(F1 내지 F5 참조). The blowing fan 10 includes a motor body 13 and a rotary vane 12 coupled to a rotary shaft of the motor body 13. The rotary vane 12 is coupled to the motor main body 13 through the bosses 11. The blowing fan 10 is installed at the center of the inside of the cylindrical fan housing 21. The blower fan 10 is fixed and supported by the center of the fan housing 21 by the fan support 23. The fluid in front of the fan housing 21 is fed backward through the fan housing 21 by the start of the blowing fan 10 (see F1 to F5).
브래킷수단이 팬하우징(21)으로 하여금 환풍구(H)가 설치된 벽체의 전면(前面)로부터 이격되게 지지되도록 한다. 브래킷수단은 일단은 팬하우징의 선단(21a)에 연결되고 타단은 벽체(W)에 고정되는 3개의 다리(22) 형태로 되어 있을 수 있다. 브래킷수단은 형태는 다양하게 안출될 수 있다. 예를 들어, 측벽에 다수의 구멍이 타공되어 있는 원통형 박스 또는 케이싱 형태로 제공될 수도 있다(도 4 내지 도 6 참조). 이 경우는 다리(22) 보다는 안정적으로 팬하우징(21)을 지지할 수 있을 것이다. 브래킷수단은 팬하우징(21)과 환풍구(H) 사이에 환형공간을 만들기 위한 것이다. So that the bracket means allows the fan housing 21 to be supported so as to be spaced apart from the front surface of the wall provided with the ventilation hole (H). The bracket means may be in the form of three legs 22, one end of which is connected to the front end 21a of the fan housing and the other end is fixed to the wall W. [ The shape of the bracket means can be varied. For example, it may be provided in the form of a cylindrical box or casing in which a plurality of holes are formed in the side wall (see Figs. 4 to 6). In this case, the fan housing 21 can be more stably supported than the legs 22. The bracket means is for making an annular space between the fan housing (21) and the ventilation hole (H).
이 브래킷수단에 의하면, 팬하우징(21) 내부는 물론 팬하우징(21)과 환풍구(H) 사이의 환형공간을 통해서도 유체가 유입되어 F3의 흐름을 따라 환풍구(H)를 통과하게 된다. 언급한 것처럼 베르누이 원리에 의해 외부의 공기가 추가적으로 환풍구(H)로 빨려 들어가게 되는 것이다. According to this bracket means, the fluid also flows through the annular space between the fan housing 21 and the ventilation hole H, and flows through the ventilation hole H along the flow of F3. As mentioned above, the external air is sucked into the ventilation hole (H) by the Bernoulli principle.
한편 팬하우징(21)의 직경(D2)이 상기 환풍구(H)의 직경(D1)과 같거나 그 보다 작게 되어 있다. 회전날개(12)에 의해 일어난 바람이 환풍구(H) 주변의 벽에 부딪히지 않도록 하기 위한 것이다. 팬하우징(21)과 벽체(W) 사이의 간격(G)은 전술한 바와 같다. On the other hand, the diameter D2 of the fan housing 21 is equal to or smaller than the diameter D1 of the vent hole H. So that the wind generated by the rotary vane 12 does not hit the wall around the ventilation hole H. The gap G between the fan housing 21 and the wall W is as described above.
본 발명의 또 다른 특징에 의하면, 유체의 직진성 향상을 위한 것으로서, 상기 환풍구(H)의 출구측에 제1유도관(30)이 설치된다. 제1유도관(30)은 벽체(W)에 밀착되게 설치될 수도 있고 소정의 지지대를 통해 이격되게 설치될 수도 있다. According to another aspect of the present invention, a first induction pipe (30) is provided at the outlet side of the vent hole (H) for improving the straightness of the fluid. The first induction pipe 30 may be installed in close contact with the wall W or may be spaced apart through a predetermined support.
그리고 제1유도관(30)의 외측에는 도 4에 도시된 것처럼 제2유도관(40)이 더 설치될 수 있다. 제2유도관(40)은 지지대에 의해 제1유도관(30)과 연결될 수 있다. 제2유도관(40)은 벽체(W)의 후면에 지지된다. 제2유도관(40)은 입구측보다 출구측의 직경이 작게 되어 있을 수 있다. 도시된 바에 의하면, 제2유도관(40)은 대경부(41), 경사부(43) 및 소경부(42)가 일체로 구성되어 단계적으로 단면적이 축소되는 형태를 가지고 있다. 4, a second induction pipe 40 may be further installed on the outer side of the first induction pipe 30. The second induction pipe (40) can be connected to the first induction pipe (30) by a support. The second induction pipe (40) is supported on the rear surface of the wall (W). The diameter of the second induction pipe 40 on the outlet side may be smaller than that on the inlet side. The second induction pipe 40 has a configuration in which the large diameter portion 41, the inclined portion 43 and the small diameter portion 42 are integrally formed and their sectional area is reduced stepwise.
위와 같은 구성에 의하면 송풍팬 가동시 제1위치(P1)와 제2위치(P2)에 각각 부압이 형성되게 된다. 유체의 직진성에 의해 환풍구(H) 내부의 유체 속도가 증가되기 때문이다. 이 부압은 외부의 공기를 더 흡입시키고자 하는 작용을 하게 되고 결국은 송풍량을 증폭시키게 된다. According to the above configuration, a negative pressure is formed at the first position P1 and the second position P2 when the blowing fan is operated. This is because the fluid velocity inside the vent hole H is increased due to the straightness of the fluid. This negative pressure acts to suck the outside air more and eventually amplifies the blowing amount.
이하, 본 발명의 다른 실시예를 도 4 내지 도 5를 참조하여 설명한다. Hereinafter, another embodiment of the present invention will be described with reference to Figs.
본 실시예에 의하면 전술한 브래킷수단의 다른 예가 제시된다. 본 실시예에 의하면 일측이 개구된 통형상의 커버(24)가 브래킷수단을 대체하고 있다. 커버(24)에는 플랜지(243)가 마련되어 벽체(W)에 고정시키기가 용이하게 되어 있으며, 평평한 전면판(241) 및 원통형 측판(242)에 각각 넓은 구멍(245,244)이 마련되어 유체의 유입이 원활하게 이루어질 수 있도록 하고 있다. 무엇보다도 커버(24)의 전면판(241)은 안전을 위하여 회전날개(12)로의 접근을 방지하는 기능을 수행한다. 본 실시예에서 팬하우징은 하우징지지대(25)를 통해 커버(24)의 내측벽에 설치된다. According to the present embodiment, another example of the above-described bracket means is presented. According to the present embodiment, the tubular cover 24 with one side opened is replaced with the bracket means. The cover 24 is provided with a flange 243 so as to be easily fixed to the wall W. The flat front plate 241 and the cylindrical side plate 242 are provided with wide holes 245 and 244, In order to make it possible. Above all, the front plate 241 of the cover 24 functions to prevent access to the rotary vane 12 for safety. In this embodiment, the fan housing is installed on the inner wall of the cover 24 through the housing support 25.
이하, 도 6을 참조하여 또 다른 실시예를 설명한다. Hereinafter, another embodiment will be described with reference to FIG.
본 실시예에 의하면 도 4 내지 도 5에 도시된 커버가 내부커버(24)와 외부커버(26)로 구성되도록 하고 있다. 외부커버(26)는 내부커버(24) 외부에 끼워져 회전 가능하게 설치된다. 내부커버(24)의 전면판(241)에는 결합돌기(246)가 돌출 형성되고 외부커버(26)에는 이 결합돌기(246)가 결합되는 결합홈(미도시됨)이 마련된다. According to the present embodiment, the cover shown in Figs. 4 to 5 is constituted by the inner cover 24 and the outer cover 26. Fig. The outer cover 26 is fitted outside the inner cover 24 and is rotatably installed. A coupling protrusion 246 is protruded from the front plate 241 of the inner cover 24 and a coupling groove is formed on the outer cover 26 to which the coupling protrusion 246 is coupled.
외부커버(26)의 전면판(261)과 측판(262)에도 각각 내부커버(24)와 같은 구멍(265,264)이 마련되어 있다. 외부커버(26)의 전면판(261) 중앙에는 손잡이(266)가 마련된다. 이 손잡이(266)를 회전시킴으로써 내부커버(24)와 외부커버(26)의 각 구멍(244,245,264,265)이 일치되거나 서로 어긋나게 하여 유로가 선택적으로 차폐되도록 할 수 있다. The front plate 261 and the side plate 262 of the outer cover 26 are provided with holes 265 and 264, respectively, similar to the inner cover 24. A handle 266 is provided at the center of the front plate 261 of the outer cover 26. By rotating the knob 266, the holes 244, 245, 264, and 265 of the inner cover 24 and the outer cover 26 are aligned with each other or shifted from each other, thereby selectively shielding the flow path.
이 실시예는 일반적인 종래의 환풍기와 같이 환기를 하지 않을 경우 겨울에 찬바람이 내부로 들어오거나 먼지나 벌레가 실내로 유입되는 것을 방지하기 위한 것이다. 즉 종래 환풍기에 있어서의 셔터와 같은 기능을 수행하는 것이다. This embodiment is intended to prevent a cold wind from entering into the interior of winter or to prevent dust or worms from entering the room when ventilation is not performed, as in the conventional conventional ventilator. That is, it performs the same function as the shutter in the conventional ventilator.
이하, 도 7을 참조하여 또 다른 실시예를 설명한다. 본 실시예 역시 브래킷 수단의 다른 예이다. Hereinafter, another embodiment will be described with reference to FIG. This embodiment is another example of the bracket means.
본 실시예에 의하면 커버체(27)의 전면판(271) 중앙에 큰 구멍(275)이 마련되어 있으며 그 안쪽으로는 구멍보다 면적이 넓은 차폐판(276)이 설치되고 있다. 도시되지 않았지만 차폐판(276)은 전면판(271)이나 측판(272)에 고정되어야 할 것이다. According to the present embodiment, a large hole 275 is provided in the center of the front plate 271 of the cover body 27, and a shield plate 276 having a larger area than the hole is provided in the inside thereof. Although not shown, the shield plate 276 should be fixed to the front plate 271 or the side plate 272.
물론 측면판(272)에는 이전 실시예와 마찬가지의 구멍(274)이 마련된다. 이러한 구성에 의하면 도시된 것처럼 지그재그 형태의 유로가 마련되게 된다. 이러한 구성은 회전날개(12)로의 접근을 방지하여 안전을 공고히 하는 한편, 회전시 발생되는 소음도 저감할 수 있는 효과를 제공한다. 도시되지는 않았지만 벌레의 유입을 방지하기 위한 망체가 커버체(27) 내부에 설치될 수도 있고, 도 6에 도시된 바와 유사한 방식으로 각 구멍(274,275)을 차폐하는 방식이 채용될 수도 있다. Of course, the side plate 272 is provided with a hole 274 similar to the previous embodiment. According to this configuration, a zigzag-like flow path is provided as shown in the figure. Such a configuration prevents an approach to the rotary vane 12, thereby enhancing safety, and also provides an effect of reducing noise generated during rotation. Although not shown, a network for preventing the inflow of worms may be provided inside the cover body 27, or a method of shielding the holes 274 and 275 in a similar manner as shown in Fig. 6 may be adopted.
본 발명에 의한 작용으로서, 송풍팬(10)의 작동에 의해 일어나는 유체의 흐름(F1, F2, F3, F4, F5)이 도 3과 도 4에 각각 표시된다. 본 발명에 의하면 F3의 흐름이 더 발생되며, 이에 의해 송풍량이 증가되는 터보 효과를 얻을 수 있는 것이며, 나아가 유도관에 의해 F5의 흐름이 추가됨으로써 그 작용을 더 증진시킬 수 있게 되는 것이다. 작용에 관한 보다 상세한 내용은 다른 실시예를 통해 후술한다. Fluid flows F1, F2, F3, F4 and F5 caused by the operation of the blowing fan 10 are shown in Figs. 3 and 4, respectively, as an action according to the present invention. According to the present invention, a flow of F3 is further generated, whereby a turbo effect in which the blowing amount is increased can be obtained, and further, the flow of F5 is added by the induction pipe. More details regarding the action will be described later in other embodiments.
이하, 도 8 내지 도 10을 참조하여 본 발명의 다른 실시예를 설명한다. 이하의 실시예는 작용을 위주로 하여 설명된다.  Hereinafter, another embodiment of the present invention will be described with reference to Figs. 8 to 10. Fig. The following embodiment will be described mainly on the operation.
팬하우징(21)의 중심에서 회전날개(12)가 회전하여 유체를 F1의 방향으로 토출시켜 줌으로써 제1유도관(30)으로 유체가 이송된다. 이때 제1위치(P1)에 저압이 형성되어(베르누이 정리) 유체 F3의 흐름이 생기게 된다. 이로써 유체 흐름이 증폭된 채로 제1유도관(30)을 통과하게 된다. The rotary vane 12 rotates at the center of the fan housing 21 to discharge the fluid in the direction of F1 so that the fluid is transferred to the first induction pipe 30. [ At this time, a low pressure is formed at the first position P1 (Bernoulli clearance), so that a flow of the fluid F3 is generated. This causes the fluid flow to pass through the first induction pipe 30 while being amplified.
제1유도관(30)을 통과하면서 증폭된 유체가 토출되며, 제2위치(P2)에 다시금 저압이 형성되므로 유체 F5의 흐름이 생겨 제3유도관(40)으로 통과하여 유량 증폭에 더욱 기여하게 된다. The amplified fluid is discharged while passing through the first induction pipe 30 and the low pressure is formed again at the second position P2 so that the flow of the fluid F5 is generated and passes through the third induction pipe 40 to further contribute to the flow rate amplification .
본 실시예에 의하면, 송풍팬의 회전날개(12) 전방 및 측방에는 스파이럴 형태의 보호메쉬(50,51)가 각각 설치될 수 있다 이는 유입되는 유체로 하여금 회전날개(12)의 회전방향으로 회전력을 갖도록 하기 위함이다. 이는 유체의 저항을 줄임으로써 손실과 소음을 저감하기 위한 것이다. 보호메쉬(50,51)는 보호수단으로서의 기능을 함은 물론이다. According to the present embodiment, spiral-shaped protective meshes 50 and 51 can be respectively installed on the front and the side of the rotary vane 12 of the blowing fan. This can prevent the inflowing fluid from rotating in the rotating direction of the rotary vane 12 . This is to reduce losses and noise by reducing the resistance of the fluid. It goes without saying that the protection mesh 50, 51 serves as a protection means.
그리고 제1,2유도관(30,40)의 출구측 내벽에도 각각 스파이럴 가이드(33,44)를 설치할 수 있다. 나선 형태는 물론 회전날개(12)의 회전방향과 같게 하여야 할 것이다. 이것은 통과하는 유체에 회전력을 부여하여 저항을 감쇄시키기 위한 것이다. Spiral guides (33, 44) can also be provided on the inner wall of the outlet side of the first and second induction pipes (30, 40). The spiral shape as well as the rotation direction of the rotary vane 12 should be the same. This is to apply a rotational force to the passing fluid to attenuate the resistance.
팬하우징(21), 제1유도관(30) 및 제2유도관(40)은 유체의 직진성을 높이기 위하여 각각 소정의 길이를 갖고 있는 것이 좋다. 여러 상황에 따라 그 길이가 조정될 수는 있을 것이다. The fan housing 21, the first induction pipe 30, and the second induction pipe 40 may each have a predetermined length to enhance the straightness of the fluid. The length can be adjusted according to various situations.
도 9 내지 도 10은 본 발명의 기술적 사상을 간단하게 표현한 것으로서, 송풍팬의 팬하우징(21)은 환풍구(H)로부터 이격되어 설치되고 있음을 볼 수 있다. 이에 의하여 팬하우징(21)의 측부로부터도 유속이 생김을 알 수 있다. 특히 도 10에 도시된 바에 따르면 팬하우징은 벽체(W)의 후방을 향하여 이격될 수도 있음을 예시하고 있다. 9 to 10 are simplified representations of the technical idea of the present invention. It can be seen that the fan housing 21 of the blowing fan is installed apart from the ventilation hole H. It can be seen that the flow velocity is also generated from the side of the fan housing 21. 10 illustrates that the fan housing may be spaced apart toward the rear of the wall W. As shown in FIG.
도 11 내지 도 12는 본 발명의 응용사례를 설명하기 위한 것이다. 도 11 내지 도 12는 드론(70)에 사용될 수 있는 프로펠러를 도시한다. 본 실시예에 의하면 유도관의 개수가 조정될 수 있음을 알 수 있다. 팬하우징(21)은 드론의 아암(71)에 연결된다. 도시된 바에 의하면 기존 실시예에 비하여 제3유도관(60)이 더 설치된다. 제3유도관(60)은 대경부(61), 경사부(63) 및 소경부(62)로 구성되도록 할 수 있으며, 제2유도관(40)의 외측에 설치될 수 있다. 11 to 12 illustrate application examples of the present invention. 11-12 illustrate a propeller that may be used in the drones 70. FIG. It can be seen that the number of induction tubes can be adjusted according to this embodiment. The fan housing 21 is connected to the arm 71 of the drones. According to the illustrated embodiment, the third induction pipe 60 is further provided. The third induction pipe 60 may be constituted by a large diameter portion 61, an inclined portion 63 and a small diameter portion 62 and may be provided outside the second induction pipe 40.
본 실시예는 이전 실시예에서의 벽체(W)가 없는 경우를 설명한다. 송풍팬(프로펠러)의 회전날개(12)에서 발생된 유체의 흐름은 직렬 배치된 복수의 단위 유도관을 통과하도록 할 수 있다. This embodiment describes a case in which there is no wall W in the previous embodiment. The flow of the fluid generated in the rotary vane 12 of the blowing fan (propeller) can be made to pass through a plurality of unit induction pipes arranged in series.
단위 유도관은 제1,2,3유도관(30,40,60)으로 구성될 수 있다. 각 단위 유도관이 서로 지지대에 의해 연결될 수 있고, 이들은 팬하우징(21)에 지지대를 통해 연결될 수 있다. 물론 단위 유도관의 고정방식은 다양하게 변경될 수 있다. 제1,2,3유도관(30,40,60)은 유입구의 직경이 유출구의 직경보다 크게 되어 있을 수 있으며 서로 길이방향으로 1/10 ~ 1/3 만큼 겹쳐지도록 배열될 수 있다. The unit induction pipe may be composed of the first, second and third induction pipes 30, 40 and 60. Each unit induction pipe can be connected to each other by a support, and they can be connected to the fan housing 21 through a support. Of course, the fixing method of the unit induction pipe can be variously changed. The first, second and third induction tubes 30, 40 and 60 may be arranged such that the diameter of the inlet is larger than the diameter of the outlet, and the first, second and third induction tubes 30, 40 and 60 overlap each other by 1/10 to 1/3 in the longitudinal direction.
이렇게 유도관을 통해 유량이 증폭된 상태로 전방으로 향하게 된다. 증폭의 원리는 각 유도관 가장자리에서 발생되는 부압 및 노즐효과이다.  Thus, the flow rate is amplified through the induction tube and directed forward. The principle of amplification is the negative pressure and nozzle effect generated at each induction tube edge.
