The sound absorbing member 21 serves to block the noise of the low frequency band, among the noise generated during the operation of the compressor 10. In addition, the sound insulation member 25 serves to block the noise of the low frequency band, among the noise generated during the operation of the compressor 10. In addition, the air layer 27 absorbs the noise generated during the operation of the compressor 10 and prevents it from being transferred to the outside.

보다 상세하게는, 상기 제1방음부(20)가 상기 밀폐용기(11)의 외주면을 둘러싼 상태에서, 상기 흡음부재(21)의 내면은 실질적으로, 상기 밀폐용기(11)의 외주면에 밀착된다. 이때 상기 흡음부재(21)는 적어도 그 일부가 서로 중첩되는 길이 로 형성된다. 또한 상기 흡음부재(21)는 펠트(flet)재질로 형성된다. 그리고 상기 흡음부재(21)의 외면 테두리에는 밀착부(22)가 구비된다. 상기 밀착부(22)는 실질적으로 상기 흡음부재(21)의 외면 테두리 일부가 외측으로 돌출되어 형성된다.More specifically, in a state in which the first soundproof part 20 surrounds the outer circumferential surface of the sealed container 11, the inner surface of the sound absorbing member 21 is substantially in close contact with the outer circumferential surface of the sealed container 11. . At this time, the sound absorbing member 21 is formed to have a length at least a portion thereof overlap each other. In addition, the sound absorbing member 21 is formed of a felt (flet) material. And the outer surface edge of the sound absorbing member 21 is provided with a close contact portion 22. The close contact portion 22 is formed as a portion of the outer edge of the sound absorbing member 21 protrudes outward.

상기 차음부재(25)는 상기 흡음부재(21)와 동일한 형상 및 크기로 형성된다. 그리고 상기 차음부재(25)는 그 내면이 상기 밀착부(22)에 밀착되도록 상기 흡음부재(21)의 외측에 구비된다. 따라서 상기 차음부재(25)도, 상기 제1방음부(20)가 상기 밀폐용기(11)의 외주면을 둘러싼 상태에서 그 일부가 서로 중첩된다. 실질적으로는, 상기 제1방음부(20)가 상기 밀폐용기(11)를 둘러싼 상태에서, 상기 흡음부재(21)의 내면 일부가 상기 차음부재(25)의 외면 일부에 중첩되어 밀착된다. 이와 같이, 상기 흡음부재(21)의 내면과 밀착되는 상기 차음부재(25)의 외면에는 벨크로부(26)(도 1참조)가 구비된다. 상기 벨크로부(26)는 상기 제1방음부(20)를 상기 밀폐용기(11)의 외주면을 둘러싼 상태로 고정하기 위한 것이다. 즉 상기 제1방음부(20)가 상기 밀폐용기(11)의 외주면을 둘러싼 상태에서, 상기 벨크로부(26)가 상기 흡음부재(21)의 내면에 밀착됨으로써, 실질적으로 상기 제1방음부(20)가 상기 밀폐용기(11)의 외주면을 둘러싼 상태로 고정된다.The sound insulation member 25 is formed in the same shape and size as the sound absorption member 21. And the sound insulating member 25 is provided on the outside of the sound absorbing member 21 so that the inner surface is in close contact with the contact portion 22. Accordingly, some of the sound insulation members 25 overlap each other in a state in which the first sound insulation unit 20 surrounds the outer circumferential surface of the airtight container 11. Substantially, in a state in which the first sound insulation part 20 surrounds the hermetic container 11, a portion of the inner surface of the sound absorbing member 21 overlaps and adheres to a portion of the outer surface of the sound insulating member 25. In this way, the outer surface of the sound insulating member 25 in close contact with the inner surface of the sound absorbing member 21 is provided with a velcro portion 26 (see Fig. 1). The velcro portion 26 is to fix the first soundproof portion 20 in a state surrounding the outer circumferential surface of the hermetic container 11. That is, the Velcro portion 26 is in close contact with the inner surface of the sound absorbing member 21 in a state in which the first soundproof portion 20 surrounds the outer circumferential surface of the airtight container 11, whereby the first soundproof portion ( 20 is fixed in a state surrounding the outer circumferential surface of the hermetic container 11.

그리고 상기 흡음부재(21)와 차음부재(25)는, 예를 들면, 접착제에 의하여 서로 고정될 수 있다. 보다 상세하게는, 상기 밀착부(22)에 해당하는 상기 흡음부재(21)의 외면과 상기 차음부재(25)의 내면 사이에 위치되는 접착제에 의하여 상기 흡음부재(21)와 차음부재(25)가 서로 고정된다. The sound absorbing member 21 and the sound insulating member 25 may be fixed to each other by, for example, an adhesive. More specifically, the sound absorbing member 21 and the sound insulating member 25 are formed by an adhesive disposed between the outer surface of the sound absorbing member 21 and the inner surface of the sound insulating member 25 corresponding to the close contact portion 22. Are fixed to each other.

상기 공기층(27)은 상기 흡음부재(21)와 차음부재(25) 사이, 실질적으로는, 상기 흡음부재(21)의 외면, 상기 차음부재(25)의 외면 및 상기 밀착부(22) 사이에 형성된다. 따라서 상기 공기층(27)의 두께는 상기 밀착부(22)의 돌출되는 길이에 따라서 결정될 것이다. The air layer 27 is disposed between the sound absorbing member 21 and the sound insulating member 25, and substantially between the outer surface of the sound absorbing member 21, the outer surface of the sound insulating member 25, and the adhesion part 22. Is formed. Therefore, the thickness of the air layer 27 will be determined according to the protruding length of the contact portion 22.

이하에서는 본 발명에 의한 압축기의 방음장치의 제1실시예의 작용을 첨부된 도면을 참조하여 보다 상세하게 설명한다.Hereinafter, the operation of the first embodiment of the soundproofing apparatus of the compressor according to the present invention will be described in more detail with reference to the accompanying drawings.

도 3은 본 발명의 제1실시예에 의한 소음의 차단율을 보인 그래프이다.3 is a graph showing the blocking rate of noise according to the first embodiment of the present invention.

먼저 압축기(10)가 동작, 즉 상기 압축기(10)가 유체를 압축하는 과정에서 발생되는 소음 중 저주파 대역의 소음은 흡음부재(21)에 의하여 흡수되고, 다시 공기층(27)을 통과하면서 흡수된 상태에서, 차음부재(25)에 의하여 고주파 대역의 소음이 외부로 전달되는 현상이 방지된다. 따라서 상기 압축기(10)의 동작과정에서 발생되는 소음이 보다 효율적으로 차단된다.First, the operation of the compressor 10, that is, the noise of the low frequency band among the noise generated in the process of compressing the fluid is absorbed by the sound absorbing member 21, and again absorbed while passing through the air layer 27. In the state, the phenomenon in which the noise of the high frequency band is transmitted to the outside by the sound insulating member 25 is prevented. Therefore, the noise generated during the operation of the compressor 10 is blocked more efficiently.

도 3을 참조하면, 본 발명에 의한 압축기의 방음장치를 사용한 경우의 소음의 차단율을 도시한 곡선(A)과 공기층을 제외한 흡음부재 및 차음부재를 포함하는 방음장치를 사용한 경우의 소음의 차단율을 도시한 곡선(B)을 비교하면, 본 발명의 경우에 전체적으로 소음의 차단율이 증가됨을 알 수 있다. 특히, 본 발명에 의하면, 저주파 대역의 소음의 차단이 현저히 증가됨을 알 수 있다.Referring to FIG. 3, the cutoff rate of the noise in the case of using the sound insulation device including the sound absorbing member and the sound absorbing member except the air layer and the curve (A) showing the cutoff rate of the noise in the case of using the soundproof device of the compressor according to the present invention. Comparing the curve (B) shown, it can be seen that the blocking rate of the noise as a whole increases in the case of the present invention. In particular, according to the present invention, it can be seen that the blocking of noise in the low frequency band is significantly increased.

이하에서는 본 발명에 의한 압축기용 방음장치의 제2실시예를 첨부된 도면을 참조하여 보다 상세하게 설명한다.Hereinafter, with reference to the accompanying drawings a second embodiment of the soundproofing device for a compressor according to the present invention will be described in more detail.

The partition 33 is for partitioning the air layer 37. The partition 33 is also formed by protruding a part of the sound absorbing member 31 in the same manner as the close contact portion 32. Substantially, the close contact portion 32 and the partition portion 33 form a lattice shape as a whole.

따라서 상기 밀착부(32)와 구획부(33)가 차음부재(35)의 그 내면에 밀착된 상태에서, 상기 흡음부재(31)와 차음부재(35)가 고정되면, 양자 사이에는 다수개의 공기층(37)이 형성된다. 즉, 본 실시예에서는, 상기 흡음부재(31)의 외면, 상기 차음부재(35)의 내면 및 상기 밀착부(32) 사이에 형성되는 상기 공기층(37)이 상기 구획부(33)에 의하여 다수개로 구획되는 것이다. 상기 공기층(37)의 구획되는 개수는, 상기 구획부(33)의 형상에 따라서 상이하게 결정될 것이다.Therefore, when the sound absorbing member 31 and the sound insulating member 35 are fixed in a state where the close contact portion 32 and the partition portion 33 are in close contact with the inner surface of the sound insulating member 35, a plurality of air layers are formed therebetween. 37 is formed. That is, in the present embodiment, the partition portion 33 includes a plurality of air layers 37 formed between the outer surface of the sound absorbing member 31, the inner surface of the sound insulating member 35, and the close contact portion 32.
