본 고안은 각종 건물이나 공장등에서 실내공기의 온도, 습도등을 자동 조절시켜주는 공기 조화실이나 각종소음(騷音)이 발생하는 소음실등에서 발생하는 각종 소음을 제거하기 위하여 공조기나 소음원의 전,후방에 착설사용하는 닥트 소음기용 흡음체에 관한 것으로, 전, 후방이 개방된 닥트본체내에 여러개의 흡음체를 삽입착설하되. 유리섬유(Class Wool)를 충진시킨 중앙부 양측에 합성수지재 필름과 유리천(Glass Cloth)및 여러개의 흡음공을 형성한 보호판을 단계적으로 구성시켜 임의의 두께로 형성한 흡음체를 상호 적당한 간격을 유지하도록 착설하므로서 닥트 소음기의 크기를 필요에 따라서 임의의 크기로 조절 형성할 수 있게 한 것이다.The present invention is designed to remove various noises from the air conditioning room that automatically adjusts the temperature and humidity of indoor air in various buildings and factories, or the noise room where various noises are generated. A sound absorbing body for a duct silencer installed in the rear, wherein a plurality of sound absorbing bodies are inserted into and installed in the duct body having an open front and rear sides. Synthetic film and glass cloth and protective plates formed with several sound-absorbing holes are formed on both sides of the center part filled with glass wool, and the sound absorbers formed at arbitrary thicknesses are maintained at appropriate intervals. By installing so that the size of the duct silencer can be adjusted to any size as needed.

종래에도 공기 조화기나 각종 소음 발생원에서 발생하는 각종 소음을 제거하기 위한 여러종류의 소음장치들이 있었으나 그 대부분이 필요에 따라서 임의로 크기를 조절할 수 없는 고정적인 것이었으며, 구조도 복잡하였던 것이다.Conventionally, there have been various kinds of silencers for removing various noises generated from an air conditioner or various noise sources, but most of them are fixed and cannot be arbitrarily adjusted in size as necessary.

본 고안은 많은 소음이 발생하는 공기조화기 또는 각종 소음 발생원의 전. 후방에 착설하되, 필요에 따라서 닥트 본체를 임의의 크기로 조절하여 구성할 수 있으며 닥트 본체내에 삽입 착설하는 흡음체를 임의의 두께로구성하여 적당한 수량을 삽입 착설하므로서, 각종 소음이 여러개의 흡음체 상호간에 구성된 간견부를 통과할때 소음을 흡입 제거하도록 된 닥트 소음기를 제공하고져 함에 고안의 목적이 있는 것으로, 이를 첨부도면에 의하여 상세히 설명하면 다음과 같다.The present invention is an air conditioner that generates a lot of noise or various noise sources. It can be installed in the rear, but can be configured by adjusting the duct body to an arbitrary size if necessary, and the sound absorbing body inserted and installed in the duct body can be formed in any thickness by inserting and installing the appropriate quantity, so that various noises are absorbed. The purpose of the present invention is to provide a duct silencer, which is configured to suction and remove noise when passing through the interleaved parts configured to each other, which will be described in detail with reference to the accompanying drawings.

전. 후방을 개방시킨 닥트본체(1)내에 임의의 두께로 양측면에 여러개의 흡음공(3)을 가진 흡음체(2)를 상로간에 적당한 간격부(4)를 유지하도록 착설하여 닥트 소음기로 사용한다.I'm. In the duct main body 1 having the rear open, a sound absorbing body 2 having a plurality of sound absorbing holes 3 on both sides at an arbitrary thickness is installed so as to maintain an appropriate spacing 4 between the furnaces and used as a duct silencer.

본 고안에서 닥트본체(1)내에 삽입 착설되는 흡음체(2)는 필요에 따라서 임의의 두께로 구성하되, 중앙부에 유리섬유(5)를 충진시키고, 그양측에 합성수지재필름(6)과 유리천(7)을 단계적으로 착설한 다음, 여러개의 흡음공(3)을 형성한 보호판(8)을 착설하여서 되는 것이다.In the present invention, the sound absorbing body 2 inserted into and installed in the duct main body 1 may be formed to an arbitrary thickness as necessary, and the glass fiber 5 is filled in the center thereof, and the synthetic resin film 6 and the glass on both sides thereof. After the cloth 7 is laid in stages, the protective plate 8 in which several sound-absorbing holes 3 are formed is laid.

이와 같은 흡음체(2)를 사용한 닥트 소음기는 각종 소음이 밭생하는 공기 조화기나 소음발생원의 전,후방에 착설형성되는 닥트에 닥트본체(1)의 개방된, 전,후방을 밀착되도록 고정 착설하므로서, 각종 소음이 발생하여 닥트본체(1)내의 흡음체(2)사이에 형성된 간격부(4)를 통과할때 흡음체(2) 양측면의 보호판(8)에 형성된 여러개의 흡음공(3)에 의하여 소음을 흡입하여서 흡음체(2)내부에 단계적으로 구성된 유리섬유(5)와 합성수지재필름(6) 및 유리천(7)에 의하여 소음이 제거되는 것이다.The duct silencer using the sound absorbing body 2 is fixedly installed so that the open, front and rear of the duct body 1 closely adheres to the air conditioner in which various noises are generated or the duct formed in front and rear of the noise source. When various noises are generated to pass through the gaps 4 formed between the sound absorbing bodies 2 in the duct body 1, the sound absorbing holes 3 formed in the protective plates 8 on both sides of the sound absorbing bodies 2 are provided. The noise is removed by the glass fiber 5 and the synthetic resin film 6 and the glass cloth 7 configured in stages in the sound absorbing body 2 by sucking the noise.

이러한 본 고안의 닥트 소음기는 공기조화기나 소음발생원의 형편에 따라서 닥트본체(1)를 형성한 다음, 닥트본체(1)내에 삽입착설하는 흡음체(2)를 임의의 두께와 크기로 구성하여서 적당한 수량을 착설 할 수 있으며, 필요에 따라서는 닥트 본체(1)와 흡음체(2)를 첨부도면 제1도 내지 제3도에 도시된 바와 같이 직사각체로 구성할뿐 아니라, 첨부도면 제4도에 원통형의 흡음체(2)를 예시한 바와 같이 닥트본체(1)와 흡음체(2)를 원통형으로 구성할 수도 있는 것이다.The duct silencer according to the present invention forms a duct main body 1 according to the condition of an air conditioner or a noise source, and then forms a sound absorbing body 2 inserted into and installed in the duct main body 1 at an arbitrary thickness and size. If necessary, the duct main body 1 and the sound absorbing body 2 may be formed in a rectangular shape as shown in FIGS. 1 to 3 as shown in FIG. As illustrated in the cylindrical sound absorbing body 2, the duct body 1 and the sound absorbing body 2 may be configured to have a cylindrical shape.
