밀폐형 압축기의 흡입소음 저감장치Suction noise reduction device of hermetic compressor

본 고안은 밀폐형 압축기의 흡입소음 저감장치에 관한 것으로, 특히 압축기의 기본 성능을 떨어뜨리지 않고 소음을 저감시킴으로 고효율 및 저소음 압축기의 개발이 용이하도록한 밀폐형 압축기의 흡입소음 저감장치에 관한 것이다.The present invention relates to a suction noise reduction device for a hermetic compressor, and more particularly, to a suction noise reduction device for a hermetic compressor that facilitates the development of a high efficiency and low noise compressor by reducing noise without deteriorating the basic performance of the compressor.

종래의 기술에 의한 밀폐형 압축기의 흡입소음 저감장치는 제1도에 도시한 바와 같이, 냉매를 흡입하는 흡입파이프(1)와, 그 흡입파이프의 선단부에 설치한 공명통(2)과, 상기 흡입파이프(2)의 끝단부에 고정한 흡입머플러(3)와, 그 흡입머플러의 끝에 위치하며 흡입밸브(5)를 구비한 헤드(4)로 구성된다.As shown in Fig. 1, the suction noise reducing apparatus of the hermetic compressor according to the prior art is provided with a suction pipe 1 for sucking a refrigerant, a resonance tube 2 provided at the tip of the suction pipe, A suction muffler 3 fixed to an end portion of the suction muffler 2 and a head 4 having a suction valve 5 positioned at the end of the suction muffler.

이와 같이 구성된 종래의 기술에 의한 밀폐형 압축기의 흡입소음 저감장치는 공명통(2)의 체적(V)이나, 공명통의 입구유로 길이(A)나, 입구유로의 폭(B)을 적절히 조정하여, 발생하는 소음의 특정주파수를 저감할수 있고, 흡입파이프 관의 직경(D)과 길이를 조정하여 소음저감 효과를 발휘할수 있으며, 흡입머플러(3)의 내부로 삽입되는 흡입파이프의 길이(C)를 최적화하여 소음을 저감할수 있다.The apparatus for reducing suction noise of the hermetic compressor according to the conventional art having the above-described configuration appropriately adjusts the volume V of the resonance cylinder 2, the length A of the inlet channel of the resonance cylinder and the width B of the inlet channel, (D) and the length of the suction pipe can be adjusted to achieve a noise reduction effect, and the length C of the suction pipe inserted into the suction muffler 3 can be optimized Noise can be reduced.

동작을 살펴보면, 흡입밸브(5)가 열리면서 냉매가스가 흡입파이프 입구측으로 흡입되고, 흡입밸브(5)가 닫히면서 흡입이 중단되는 단속흐름 즉 불연속흐름이 발생된다.In operation, when the suction valve 5 is opened, the refrigerant gas is sucked into the suction pipe inlet side, and the suction valve 5 is closed.

종래의 기술에 의한 밀폐형 압축기의 흡입소음 저감장치는 냉매흡입을 위해 흡입 파이프(1)가 항상 열려 있어야 하므로, 압축기 운전시 발생하는 소음을 완전히 차단하는 것이 불가능하고, 흡입밸브(5)가 닫히면서 발생하는 밸브 타격음을 완전히 차단하지 못하며, 구조가 복잡하고 제조공정이 많아지게 되는 문제점이 있는 바, 본 고안의 목적은 상기와 같은 문제점을 고려하여 안출한 것으로, 압축기의 기본 성능을 떨어뜨리지 않고 소음을 저감시킴으로 고효율 및 저소음 압축기의 개발이 용이하도록 한 밀폐형 압축기의 흡입소음 저감장치를 제공함에 있다.In the suction noise reducing apparatus of the hermetic compressor according to the related art, since the suction pipe 1 is always opened for suction of the refrigerant, it is impossible to completely shut off the noise generated in the operation of the compressor, and when the suction valve 5 is closed The present invention has been made in view of the above-mentioned problems, and it is an object of the present invention to provide a compressor which can reduce the noise of the compressor without deteriorating the basic performance of the compressor, Which is capable of easily developing a high-efficiency and low-noise compressor.
