본 발명은, 흡입머플러 및 이를 갖는 압축기에 관한 것으로서, 보다 상세하게는 흡입머플러의 머플러가이드에 필터부재를 결합하는 구조를 개선한 흡입머플러 및 이를 갖는 압축기에 관한 것이다. The present invention relates to a suction muffler and a compressor having the same, and more particularly, to a suction muffler and a compressor having the same in which a structure of coupling the filter member to the muffler guide of the suction muffler is improved.

냉장고나 공기조화기 등에 채용되는 냉동사이클은 저압의 냉매를 흡입 및 압축하여 고압상태로 토출하는 압축기와, 압축기로부터 토출된 냉매를 응축하는 응축기와, 응축기로부터 응축된 냉매를 팽창시키는 팽창장치와, 팽창장치에서 팽창된 냉매가 증발되면서 주위의 공기와 열교환을 하는 증발기가 냉매관을 통해 폐회로를 이루도록 마련된다. Refrigeration cycles employed in refrigerators and air conditioners include a compressor for sucking and compressing low-pressure refrigerant and discharging the refrigerant under high pressure, a condenser for condensing the refrigerant discharged from the compressor, an expansion device for expanding the refrigerant condensed from the condenser, As the refrigerant expanded in the expansion device is evaporated, an evaporator that exchanges heat with surrounding air is provided to form a closed circuit through the refrigerant pipe.

이 중 압축기는 통상, 냉매의 압축이 수행되는 압축유닛과, 냉매를 압축하기 위한 압축동력을 제공하는 구동유닛과, 압축유닛 및 구동유닛을 외부로부터 밀폐시키는 케이싱과, 증발기로부터 유입되는 냉매를 케이싱의 내부로 안내하는 흡입관과, 압축유닛에서 압축된 냉매를 케이싱의 외부로 토출하여 응축기로 보내는 토출관을 포함한다.Among them, the compressor generally includes a compression unit in which the compression of the refrigerant is performed, a driving unit providing compression power for compressing the refrigerant, a casing for sealing the compression unit and the driving unit from the outside, and a refrigerant flowing from the evaporator. It includes a suction pipe for guiding the inside of the discharge tube, and the discharge tube to discharge the refrigerant compressed in the compression unit to the outside of the casing to the condenser.

일반적으로, 압축유닛과 케이싱 사이에는 압축유닛으로 공급되는 냉매의 유동소음을 줄이기 위한 흡입머플러가 설치되며, 흡입머플러는 흡입관으로부터 유입되는 냉매가 흡입머플러의 내부로 유입되는 것을 안내하는 머플러가이드를 포함하 고, 머플러가이드의 내부에는 유입되는 냉매로부터 이물질을 걸러주는 그물망 형상의 필터부재가 결합된다.

In addition, since the filter member is coupled to the inside of the muffler guide by an adhesive or heat fusion method, there is a problem in that the production process is added thereto, thereby increasing the production cost of the compressor and lowering the productivity.

따라서, 본 발명의 목적은, 머플러가이드 및 필터부재의 변형을 방지하여 머플러가이드를 케이싱에 밀착시킴으로써 효율을 높일 수 있으며 소음을 효과적으로 저감시킬 수 있는 흡입머플러 및 이를 갖는 압축기를 제공하는 것이다. Accordingly, an object of the present invention is to provide a suction muffler and a compressor having the same, which can increase efficiency by effectively preventing the muffler guide and the filter member from being in close contact with the casing guide and the noise.
