본 발명은 흡입관으로부터의 냉매를 냉매압축용 실린더장치에 공급하며, 실린더장치에 고정되는 머플러본체와 머플러본체에 조립되는 머플러커버를 가지는 밀폐형압축기용 흡입머플러에 관한 것이다.The present invention relates to a suction muffler for a hermetic compressor which supplies a refrigerant from a suction pipe to a cylinder device for refrigerant compression, and has a muffler body fixed to the cylinder device and a muffler cover assembled to the muffler body.

냉장고 등의 냉동장치에서는 증발기로부터의 기상냉매를 압축하여 고압의 냉매기체로 만들어 응축기에 제공하는 압축기가 마련된다. 도 5는 종래의 밀폐형압축기용 흡입머플러 부분을 실린더헤드 측에서 본 부분단면도이고, 도 6은 도 5의 Ⅱ-Ⅱ선에 따라 자른 단면도이다. 이 도면들에 도시된 바와 같이, 밀폐형압축기의 하부영역에 설치되는 냉매압축용 실린더장치(111)의 냉매흡입구(113)와 연통되도록 실린더헤드(112) 부분에 설치되는 흡입머플러(121)는 외부로부터 유입되는 냉매를 수령하여 실린더장치(111)로 공급할 수 있도록 되어 있다. 흡입머플러(121)에는 외부로부터 냉매가 유입되는 냉매흡입용 흡입관(117)이 연결되어 있고, 이 냉매흡입용 흡입관(117)은 압축기 외부의 증발기와 연결되어 냉매를 압축기 내부로 공급한다. 이 냉매흡입용 흡입관(117)의 외경부에는 관상의 접속스프링관(119)의 일단이 끼워지고, 타단은 흡입머플러(115)의 흡입포트(127)의 내경부에 삽입되어 있어, 냉매흡입용 흡입관(117)을 통해 유동해 온 냉매가 이 접속스프링관(119)을 통과하여 흡입머플러(121)로 유입된다.In a refrigerating device such as a refrigerator, a compressor is provided which compresses the gaseous refrigerant from the evaporator to form a high-pressure refrigerant gas and provides it to the condenser. 5 is a partial cross-sectional view of a conventional hermetic compressor suction muffler from the cylinder head side, Figure 6 is a cross-sectional view taken along the line II-II of FIG. As shown in these figures, the suction muffler 121 is installed in the cylinder head 112 portion to communicate with the refrigerant suction port 113 of the refrigerant compression cylinder device 111 installed in the lower region of the hermetic compressor. The refrigerant flowing in is received and can be supplied to the cylinder device 111. The suction muffler 121 is connected to the suction pipe 117 for the refrigerant suction from the outside, the refrigerant suction suction pipe 117 is connected to the evaporator outside the compressor to supply the refrigerant into the compressor. One end of the tubular connecting spring tube 119 is fitted into the outer diameter portion of the suction tube 117 for refrigerant suction, and the other end is inserted into the inner diameter portion of the suction port 127 of the suction muffler 115, so The refrigerant flowing through the suction pipe 117 flows into the suction muffler 121 through the connection spring pipe 119.

흡입머플러(121)는 실린더장치(111)에 고정되어 냉매흡입용 흡입관(117)으로부터 냉매를 실린더장치(111)에 공급하는 머플러본체(123)와, 연부상에 형성된 걸림부가 머플러본체(123)의 연부와 대응결합되어 머플러본체(123)에 조립되어 머플러본체(123)와 함께 냉매수용부를 형성하는 머플러커버(125)로 이루어져 있다. 머플러본체(123)와 머플러커버(125)는, 이들간의 접속연부를 확대하여 도시한 단면도인 도 7에 도시된 바와 같이, 머플러본체(123)의 연부상의 외측벽의 일부가 절취되어 형성된 후크걸림부(128)와 머플러커버(125)의 접속후크부(129)가 단순결합됨으로써, 조립된다.The suction muffler 121 is fixed to the cylinder device 111 and the muffler body 123 for supplying the refrigerant from the suction pipe 117 for refrigerant suction to the cylinder device 111, and the engaging portion formed on the edge portion of the muffler body 123 Correspondingly coupled to the edge of the muffler body 123 is composed of a muffler cover 125 to form a refrigerant receiving portion together with the muffler body 123. The muffler body 123 and the muffler cover 125 have hook hook portions formed by cutting a part of the outer wall on the edge of the muffler body 123, as shown in FIG. The connection hook portion 129 of the 128 and the muffler cover 125 is assembled by simple coupling.

따라서, 압축기를 조립할 때, 특히 냉매흡입용 흡입관(117), 흡입머플러(121) 및 실린더장치(111)를 조립할 때에는, 실린더장치(111)의 실린더헤드(112) 부분에 흡입머플러(121)의 머플러본체(123)를 조립하고, 머플러본체(123)의 일측 연부영역에 설치된 냉매흡입포트(127)와 냉매흡입용 흡입관 사이에 접속스프링관(119)을 개재시킨다. 그 다음에, 머플러커버(125)의 접속후크부(129)를 머플러본체(123)의 후크걸림부(128)에 단순결합시켜, 흡입머플러(121)의 조립을 완료하게 된다.Therefore, when assembling the compressor, in particular when assembling the refrigerant suction suction pipe 117, the suction muffler 121 and the cylinder device 111, the suction muffler 121 of the cylinder head 112 of the cylinder device 111 The muffler body 123 is assembled, and a connection spring tube 119 is interposed between the refrigerant suction port 127 and the refrigerant suction suction pipe provided at one edge region of the muffler body 123. Then, the connecting hook portion 129 of the muffler cover 125 is simply coupled to the hook catching portion 128 of the muffler body 123 to complete the assembly of the suction muffler 121.

이러한 과정을 거쳐 조립된 압축기에서는, 냉매흡입용 흡입관(117)으로부터의 냉매가 접속스프링관(119)을 통과하여 흡입머플러(121)로 유입되어 실린더헤드(112) 부분의 냉매흡입구(113)를 통해 실린더장치(111) 내부로 흡입되어 압축된 후에, 다시 실린더헤드(112) 부분의 냉매토출구(114)를 통해 토출된다.In the compressor assembled through such a process, the refrigerant from the suction suction pipe 117 passes through the connection spring pipe 119 and flows into the suction muffler 121 to open the refrigerant suction opening 113 of the cylinder head 112. After being sucked into the cylinder device 111 and compressed, it is again discharged through the refrigerant discharge port 114 of the cylinder head 112 portion.

이러한 종래의 머플러에서는 그 내부에 고온고압의 냉매가스가 항상 충전되어 있고, 실린더장치(111)의 작동에 따라 내부압력의 변동이 심하므로 머플러본체(123)와 머플러커버(125)의 상호 접속부에서 틈새가 발생하며, 이 틈새를 통해 실린더장치(111)의 밸브작동에 따른 소음이 밖으로 새어나가게 된다. 또한, 흡입머플러(121)의 내외부에는 고온의 냉매가스가 분포되어 있어, 고온냉매가스에 의하여 흡입머플러(121)가 열팽창하게 되어 머플러본체(123)와 머플러커버(125)의 접속연부의 틈새는 더욱 커지게 된다.In the conventional muffler, the refrigerant gas of high temperature and high pressure is always filled therein, and since the internal pressure fluctuates severely according to the operation of the cylinder device 111, the muffler main body 123 and the muffler cover 125 are interconnected at the There is a gap, through which the noise caused by the operation of the valve of the cylinder device 111 is leaked out. In addition, since the refrigerant gas of high temperature is distributed inside and outside the suction muffler 121, the suction muffler 121 is thermally expanded by the high temperature refrigerant gas, so that the gap between the muffler body 123 and the muffler cover 125 is connected. It gets bigger.

따라서, 본 발명의 목적은 머플러본체와 머플러커버가 견고하게 결합되도록 흡입머플러의 결합구조를 개선함으로써, 소음이 외부로 새어나가는 것을 방지할 수 있는 밀폐형압축기용 흡입머플러를 제공하는 것이다.Accordingly, it is an object of the present invention to improve the coupling structure of the suction muffler so that the muffler main body and the muffler cover are firmly coupled, thereby providing a suction muffler for a hermetic compressor that can prevent noise from leaking to the outside.
