상기와 같은 목적을 달성하기 위한 본 고안은 양방향 송풍시스템의 싸이렌샤장치를 구성함에 있어서, 싸이렌샤케이싱의 내주면에 소정의 간극을 두고 다수의 통기공이 구비된 내면흡음관이 설치되고, 상기 싸이렌샤케이싱의 내주면과 내면흡음관의 사이에 흡음부재가 충진되는 한편, 상기 싸이렌샤케이싱의 내주면과 내면흡음관 사이에 이들을 이등분하여 소음이 전달되는 것을 차단하는 소음차단벽이 설치된 특징이 있다.The present invention for achieving the above object in the construction of the sirensha device of the two-way blowing system, the inner sound absorbing tube having a plurality of vents with a predetermined gap on the inner circumferential surface of the sirenshacas is installed, the siren A sound absorbing member is filled between the inner circumferential surface of the shading casing and the inner surface sound absorbing tube, and a noise blocking wall is provided between the inner circumferential surface of the siren casing and the inner surface sound absorbing tube to divide the two into two to block the transmission of noise.

이하, 본 고안은 바람직한 일실시예를 첨부된 도면에 의거하여 성세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings a preferred embodiment as follows.

도 2는 본 고안에 따른 싸이렌샤장치의 사시도이고, 도 3은 도 3의 단면도이며, 도 4는 본 고안에 따른 사이렌서장치가 설치된 송풍시스템의 개략적인 구성도이다.Figure 2 is a perspective view of the silencer device according to the present invention, Figure 3 is a cross-sectional view of Figure 3, Figure 4 is a schematic configuration diagram of a blowing system is installed a silencer device according to the present invention.

먼저, 원통형상의 팬케이싱(110)의 내부에는 정.역회전이 가능도록 모터 (111)가 정중앙부에 설치되며, 상기 모터(111)의 회전자 케이싱(112) 외주부에 다수의 팬(113)이 고정 설치되며, 상기 회전자 케이싱(112)의 양단으로 돌출된 지지축 (114)이 십자형 허브(115)에 지지된다.First, inside the cylindrical fan casing 110, the motor 111 is installed at the center of the center to enable forward and reverse rotation, and the plurality of fans 113 at the outer circumference of the rotor casing 112 of the motor 111. It is fixedly installed, the support shaft 114 protruding from both ends of the rotor casing 112 is supported by the cross-shaped hub (115).

상기 팬케이싱(110)의 양 단부로 설치되는 흡.배기용 풍량조절베인(120) 내부에는 나팔관형상으로 공기의 유량을 조절하는 유량조절 댐퍼장치가 설치된다.A flow control damper device for adjusting the flow rate of air in the shape of a fallopian tube is installed inside the air flow rate adjusting vane 120 installed at both ends of the fan casing 110.

상기 풍량조절베인(120)의 양 단부에 각각 설치되는 싸이렌샤케이싱(130)은 도 3과 같이 그 내주면에 공명관을 두고 다수의 통기공(132)이 구비된 내면흡음관 (131)이 설치되고, 상기 싸이렌샤케이싱(130)의 내주면과 내면흡음관(131)의 사이에 흡음부재(133)가 충진되는 한편, 상기 싸이렌샤케이싱(130)의 내주면과 내면흡음관(131) 사이에 이들을 이등분하여 소음이 전달되는 것을 방지할 수 있는 소음차단벽(134)이 설치된다.Silencer casing 130 is installed at both ends of the air flow control vane 120 is installed inside the sound absorbing tube 131 having a plurality of vent holes 132 with a resonance tube on its inner peripheral surface as shown in FIG. While the sound absorbing member 133 is filled between the inner circumferential surface of the siren chuck casing 130 and the inner surface sound absorbing tube 131, the sound absorbing member 133 is divided into two parts between the inner circumferential surface of the sirens casing 130 and the inner sound absorbing tube 131. The noise blocking wall 134 is installed to prevent noise from being transmitted.

상기 싸이렌샤케이싱(130)의 각 단부에는 흡배기용 벨마우스(140)가 설치되어 공기의 흡.배기를 원활하게 한다.At each end of the siren chuck casing 130, a bell mouth 140 for intake and exhaust air is installed to smoothly intake and exhaust air.

상기와 같이 구성된 싸이렌샤장치의 작용을 설명하면 다음과 같다.Referring to the operation of the silencer device configured as described above are as follows.

도 4와 같이 유량조절 댐퍼장치(121)의 조작수단을 조작하여 날개를 적당히 개방한 다음, 팬케이싱(110)의 내부에 설치되어진 모터(111)를 일방향으로 구동하게 되는데, 이와 동시에 회전자 케이싱(112)가 회전하여 그 외주부에 설치된 다수의 팬(113)이 구동된다. 이때, 상기 팬(113)이 회전자 케이싱(112)에 설치되어 있기 때문에 이의 회전을 균일하게 하는 동시에 기계적 진동 및 소음을 극소화시킴은 물론, 회전자 케이싱(112)에 팬(113)이 직접 설치됨에 따라 구동력도 작게들며, 고속회전에 따르는 플라이 휠 효과가 증대되어 효율특성과 진동특성이 크게 향상된다.As shown in Figure 4 by operating the operating means of the flow control damper device 121 to open the wings properly, and to drive the motor 111 installed in the inside of the fan casing 110 in one direction, at the same time rotor casing The 112 is rotated to drive a plurality of fans 113 installed at the outer circumference thereof. At this time, since the fan 113 is installed in the rotor casing 112, the rotation of the fan 113 is uniform and the mechanical vibration and noise are minimized, as well as the fan 113 is directly installed in the rotor casing 112. As a result, the driving force is also reduced, and the flywheel effect due to the high speed rotation is increased, thereby greatly improving the efficiency characteristics and vibration characteristics.

상기 팬(113)이 구동하게 되면 도 3과 같이 팬케이싱(110)으로부터 송출된 공기는 풍량조절베인(120)의 유도를 받아 싸이렌샤장치의 싸이렌샤케이싱(130) 내부로 송출되는데, 상기 싸이렌샤케이싱(130)의 내경이 팬케이싱(110)의 내경보다 다소 넓게 형성되어 있으므로 팬케이싱(110)을 통한 공기가 싸이렌샤케이싱(130)내부에 확산되면서 공기의 속도가 저하되므로 소음이 다소 저감되며, 팬케이싱(110)과 싸이렌샤케이싱(130)에서 발생되는 나머지의 소음은 내면흡음관(131)의 통기공(132)으로 흡입되면서 재차 저감된 다음, 싸이렌샤케이싱(130)과 내면흡음관 (131)의 사이에 설치되어진 흡음부재(133)에서 다시 제거되고, 이로 흡입된 소음은 소음차단벽(134)에 막혀 완전히 소멸된다.When the fan 113 is driven, the air sent from the fan casing 110 as shown in FIG. 3 is sent to the inside of the sirens casing 130 of the sirens device under the guidance of the air flow control vane 120. Since the inner diameter of the shading casing 130 is formed to be slightly wider than the inner diameter of the pan casing 110, the air through the pan casing 110 diffuses into the siren crushing casing 130, and thus the speed of the air decreases, thereby slightly reducing the noise. The remaining noise generated from the pan casing 110 and the siren chuck casing 130 is reduced again while being sucked into the vent hole 132 of the inner sound absorbing tube 131, and then the siren crush casing 130 and the inner sound absorbing are absorbed. The sound absorbing member 133 installed between the pipes 131 is removed again, and the noise sucked by this is blocked by the noise blocking wall 134 and completely extinguished.

따라서 본 고안은 싸이렌샤장치의 싸이렌샤케이싱(130) 내주면에 소정의 간극을 두고 내면흡음관(131)을 설치하고, 이들 사이에 흡음부재(133)를 설치하는 한편, 상기 싸이렌샤케이싱(130)의 내주면과 내면흡음관(131) 사이에 이들을 이등분할 수 있는 소음차단벽(134)을 설치하여 공기흐름에 의한 간섭을 극소화시킴으로써 소음을 크게 줄이는 동시에 압력손실을 극소화하는 한편, 사이렌서장치의 구조를 단순화시켜 이의 제작을 용이하게 함은 물론이고 이에 따른 제작비용을 최소화할 수 있는 매우 유용한 효과가 있다.Therefore, the present invention provides an inner sound absorbing tube 131 with a predetermined gap on the inner circumferential surface of the sirens casing 130 of the silencer device, and installs a sound absorbing member 133 therebetween, while the siren sash casing 130 is provided. Between the inner circumferential surface of the inner surface and the inner sound absorbing tube 131, a noise blocking wall 134 capable of dividing them into two parts is provided to minimize the interference caused by the air flow, thereby greatly reducing the noise and minimizing the pressure loss. By simplifying the structure to facilitate its manufacture, there is a very useful effect that can minimize the production cost accordingly.

본 고안은 상술한 특정의 바람직한 실시예에 한정되지 아니하며, 청구 범위에서 청구하는 본 고안의 요지를 벗어남이 없이 당해 발명이 속하는 기술 분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변형 실시가 가능한 것은 물론이고, 그와 같은 변경은 청구 범위 기재의 범위내에 있게 된다.The present invention is not limited to the above-described specific preferred embodiment, and any person having ordinary skill in the art to which the present invention pertains may make various modifications without departing from the gist of the present invention claimed in the claims. Of course, such changes will fall within the scope of the claims.
