본 고안은 냉장고용 압축기의 머플러에 관한 것으로서, 특히 토출실을 이단팽창형으로 구성하여 냉매기체의 맥동에 의한 소음을 최소화 시킬 수 있도록 한 냉장고용 압축기의 머플러에 관한 것이다.The present invention relates to a muffler for a refrigerator compressor, and more particularly, to a muffler for a refrigerator compressor configured to minimize the noise caused by the pulsation of the refrigerant gas by discharging the discharge chamber in a two-stage expansion type.

종래의 일반적인 압축기의 머플러를 보면, 크랭크축과 커낵팅로드 및 실린더의 외곽을 둘러싸고 있으면서 일측에는 흡입실이 형성되고 타측에는 토출실이 형성되어 있으며, 상기 흡입실과 토출싱의 중간에는 밸브커버가 형성되어 있다.In the conventional muffler, a suction chamber is formed on one side and a discharge chamber is formed on the other side while surrounding the crankshaft, the connecting rod and the outer periphery of the cylinder, and a valve cover is formed between the suction chamber and the discharge sink. It is.

상기와 같은 머플러는 현재 거의 모든 전 밀폐형 압축기에서 채용되고 있으나 상기 토출실이 단일 팽창형으로 형성되어 있어 실린더내에서 고압으로 저감시키지 못하고 있는 실정이다.Such a muffler is currently employed in almost all hermetic compressors, but the discharge chamber is formed in a single expansion type, which does not reduce the pressure to a high pressure in a cylinder.

본 고안은 상기의 실정을 감안하여 안출한 것으로서, 토출실의 외측벽 중간부위를 요입시켜 상기 토출실을 제1토출실과 제2토출실로 이분화시키되, 이 제1토출실과 제2토출실 사이에 소정의 통로를 형성하여 이단 팽창형의 토출실을 구성함으로써 그 전체적인 구조 및 크기의 변경없이 최대의 소음(騷音)저감 효과를 얻을 수 있도록 한 냉장고용 압축기의 머플러를 제공함에 그 목적이 있다.The present invention is conceived in view of the above situation, and dividing the discharge chamber into a first discharge chamber and a second discharge chamber by interposing an intermediate portion of the outer wall of the discharge chamber, and the predetermined discharge between the first discharge chamber and the second discharge chamber. It is an object of the present invention to provide a muffler of a compressor for a refrigerator in which a discharge path of a two-stage expansion type is formed by forming a passageway so as to obtain a maximum noise reduction effect without changing its overall structure and size.

이하, 상기의 목적을 달성하기 위한 본 고안의 바람직한 한 실시예를 첨부된 도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, a preferred embodiment of the present invention for achieving the above object will be described in detail with reference to the accompanying drawings.

밸브커버(10) 및 토출실(11)이 융출 형성된 외측판(1a)과 흡입구(12) 및 토출공(13)이 형성된 내측판(1b)이 겹쳐져 구성되는 머플러(1)에 있어서, 상기 외측판(1a)의 토출실(11) 중간 부위를 요입시켜 제1토출실(11a)과 제2토출실(11b)을 형성하되, 이들 사이에 소정크기의 통로(14)를 형성하고 상기 내측판(1b)의 제2토출실(11b)에 대응되는 부위를 적정깊이 요입시켜서 된 것이다.In the muffler (1) formed by overlapping the outer plate (1a) in which the valve cover (10) and the discharge chamber (11) are melted, and the inner plate (1b) in which the suction port (12) and the discharge hole (13) are formed, the outer side Intermediate portions of the discharge chamber 11 of the plate 1a are formed to form a first discharge chamber 11a and a second discharge chamber 11b, and a passage 14 having a predetermined size is formed therebetween, and the inner plate The site | part corresponding to the 2nd discharge chamber 11b of (1b) was made to infiltrate with appropriate depth.

도면중 미설명부호 2는 실린더, 3은 커넥팅로드, 4는 피스턴, 5는 크랭크축, 15는 토출파이프, 16은 흡입실, 17은 밸브플레이트이다.In the drawings, reference numeral 2 denotes a cylinder, 3 a connecting rod, 4 a piston, 5 a crankshaft, 15 a discharge pipe, 16 a suction chamber, and 17 a valve plate.

이와같이 구성되는 본 고안은 피스턴(4)의 흡입행정시에 흡입실(16)을 거쳐 실린더(2)내로 흡입되는 저온, 저압의 냉매 기체가 피스턴(4)의 압축행정시에 고온, 고압의 냉매기체로 되어 제1토출실(11a)로 토출되게 되는데 이때, 냉매기체가 가지고 있는 고유의 진행파는 제1토출실(11a) 벽면에 부딪히면서 반사파에 의해 일부가 상쇄되고 일부만이 통로(14)를 통해 제2토출실(11b)로 진행하게 된다. 이 과정에서 냉매기체의 맥동으로 인한 소음이 1차적으로 저감되게 되고 제2토출실(11b)로 진행된 진행파는 더욱 약화되어 그 소음이 거의 소멸되게 된다.According to the present invention, the low temperature and low pressure refrigerant gas sucked into the cylinder 2 through the suction chamber 16 during the suction stroke of the piston 4 is a high temperature and high pressure refrigerant during the compression stroke of the piston 4. The gas is discharged to the first discharge chamber 11a. At this time, the propagation wave inherent in the refrigerant gas strikes the wall of the first discharge chamber 11a and is partially canceled by the reflected wave, and only a part of it passes through the passage 14. The flow proceeds to the second discharge chamber 11b. In this process, the noise due to pulsation of the refrigerant gas is primarily reduced, and the traveling wave propagated to the second discharge chamber 11b is further weakened so that the noise almost disappears.

따라서, 본 고안에 의하면 이단 팽창형으로 구성된 토출실(11)에서 냉매 기체의 맥동을 2차에 걸쳐 약화시켜줌으로 인해 냉매 기체의 흐름으로 발생되는 소음이 크게 저감되는 효과를 얻을 수 있다.Therefore, according to the present invention, the noise generated by the flow of the refrigerant gas is greatly reduced by weakening the pulsation of the refrigerant gas in the discharge chamber 11 configured as a two-stage expansion type for a second time.
