본 고안은 송풍기의 소음저감구조에 관한 것으로, 특히 흡음판재로 구성되는 하우징에 송풍기를 내장시켜 소음의 방출을 극소화할 수 있도록 한 것이다.The present invention relates to a noise reduction structure of the blower, in particular to the built-in blower in a housing made of a sound-absorbing plate material to minimize the emission of noise.

일반적으로 송풍기에서는 모터의 구동음, 팬의 회전음, 팬과 팬커버 사이의 난기류에 의한 소음, 팬커버 및 팬블레이드의 진동음 등 많은 크고 작은 소음이 유발되고 종합적인 소음의 크기는 모터의 용량, 팬의 형상, 팬의 크기, 팬의 설치 위치등의 제반 요인들에 의해 결정된다.In general, the blower generates a lot of loud and small noises such as driving sound of the motor, rotation of the fan, noise caused by turbulence between the fan and the fan cover, and vibration of the fan cover and fan blade. It depends on various factors such as the shape of the fan, the size of the fan, and the installation position of the fan.

종래에도 상기와 같이 송풍기의 소음을 저감시키기 위한 것으로 송풍기의 주위에 표면판과 흡음재 및 다공재를 적층하여 된 흡음판을 자재로 사용하여 흠음상자를 만들어 이 흡음상자 내부에 송풍기를 장착하여서된 소음 저감구조가 안출된 바 있으나(일본 실개소 52-56602호 참조), 이는 송풍기의 소음방출을 어느정도 저감시키는 효과는 있으나 흡기구가 송풍기가 장착된 내부공간으로 부터 직접 노출되어 있어서 흡기구로의 소음 방출을 차단하지 못하기 때문에 소음 저감에 그다지 큰 효과를 거둘수가 없을 뿐만 아니라 상기 선행기술은 송풍기의 고장등 이상이 발생할 경우 도아가 없는 흡음상자로 둘러싸여 있기 때문에 이를 적극적으로 해결할 수 없는 문제점이 노출되어 있었다.In order to reduce the noise of the blower as described above, the sound absorbing plate formed by laminating the surface plate, the sound absorbing material and the porous material around the blower is used as a material to make a flaw box, and to reduce the noise by installing the blower inside the sound absorbing box. Although the structure has been devised (see Japanese Patent Application No. 52-56602), this has the effect of reducing the noise emission of the blower to some extent, but the air intake is directly exposed from the inside space where the blower is mounted, thereby preventing the emission of noise to the intake. Not only does not have a great effect on noise reduction because it is not possible because the prior art is surrounded by a sound-absorbing box without a failure in the event of a failure, such as failure of the blower was exposed to a problem that can not be actively solved.

본 고안은 상기의 문제점을 감안한 것으로 그 목적은 송풍기에서 유발되는 소음이 외부로 방출되는 것을 극소화시킬 수 있도록 함과 동시에 송풍기의 고장이 발생할 경우 쉽게 접근하여 고장부위를 보수할 수 있도록 한 송풍기의 소음저감 구조를 제공하는 것이다.The present invention has been made in view of the above problems, and its purpose is to minimize noise emitted from the blower to the outside, and at the same time, the noise of the blower to easily approach and repair the trouble part when a blower malfunction occurs. To provide an abatement structure.

본 고안은 상기의 목적을 달성하기 위하여 외측판과 다공판사이에 흡음재를 충전시킨 흡음판재로 구성되는 통상의 것에 있어서 흡기공과 송풍기사이에 격벽을 마련하되 격벽의 결여부와 흡기공이 서로 엇갈린 위치에 있도록 하여서된 특징이 있다. 또한 본 고안은 하우징의 적의개소에 출입구를 마련하고 이에 개폐도아를 설치하여서된 특징이 있다.The present invention is to provide a partition between the intake hole and the blower in a common configuration consisting of a sound absorbing plate material filled with the sound absorbing material between the outer plate and the porous plate in order to achieve the above object, but the absence of the partition and the intake hole are crossed with each other It is intended to be a feature. In addition, the present invention is characterized by providing an entrance to the hostile place of the housing and installing an opening and closing door thereto.

상기에서 하우징(20)의 외측판(21), 상판(22), 하판(23), 내부격판(24), 도아 (29)등은 흡음판재(10)로 구성되는 바, 상기 흡음판재(10)는 겉판(11)과 표면에 무수한 소공(15a)이 형성된 내측 다공판(15) 사이에 흡음재(13)를 출전시켜서 된 것으로 통상적인 것이다.In the above, the outer plate 21, the upper plate 22, the lower plate 23, the inner plate 24, the door 29, and the like of the housing 20 are constituted by the sound absorbing plate member 10, and the sound absorbing plate member 10 is provided. ) Is a conventional one obtained by discharging the sound absorbing material 13 between the outer plate 11 and the inner porous plate 15 having a myriad of small pores 15a formed on the surface thereof.

상기 흡음재(13)는 흡음성이 양호한 그라스울 또는 암면등이 사용되나 이들은 강도가 비교적 약하기 때문에 흡음판재(10) 내부에 격자상의 보강프레임(12)등을 설치하면 강도가 충분히 보완된다.The sound absorbing material 13 is used glass wool or rock wool with good sound absorption, but because they are relatively weak in strength, if the lattice reinforcement frame 12 or the like is installed inside the sound absorbing plate 10, the strength is sufficiently compensated.

또한 흡음재(13)의 파손을 방지하지 위해 흡음재(13)와 다공판(15) 사이에 직포, 필름등의 재질로 된 보호재(14)를 개재시키는 것이 바람직하다.In addition, in order to prevent damage to the sound absorbing material 13, it is preferable to interpose a protective material 14 made of a material such as a woven fabric or a film between the sound absorbing material 13 and the porous plate 15.

제2도에는 본 고안 한 실시예의 횡단면도가 도시되어 있는 바, 특히 이를 참조하면서 본 고안의 작용, 효과를 설명하기로 한다.2 is a cross-sectional view of an embodiment of the present invention is shown, in particular with reference to this will be described the operation, effect of the present invention.

송풍기(30)를 가동시키면 하우징(20) 내부의 공기는 팬커버(31) 후방으로 흡입되어 외측판(21)의 관통공(21a) 외부로 돌출된 팬커버(31)의 토출측으로 배출되며 하우징(20)의 외부공기는 외측판(21) 일측의 흡기망판(28)을 통해 하우징(20) 내부로 진입하게 되고 흡기유도공간(25)과 결여부(27)를 거쳐 팬커버(31) 후방으로 이동하게 된다.When the blower 30 is operated, the air inside the housing 20 is sucked to the rear of the fan cover 31 and discharged to the discharge side of the fan cover 31 protruding outside the through hole 21a of the outer plate 21. The outside air of the 20 enters the inside of the housing 20 through the intake mesh plate 28 on one side of the outer plate 21, and passes through the intake induction space 25 and the lacking part 27 to the rear of the fan cover 31. Will be moved to.
