본 발명은 압축기용 흡입머플러에 관한 것으로, 더욱 상세하게는 내부 유로구조를 개선하여 냉매의 유동손실 및 소음을 보다 효과적으로 줄일 수 있도록 마련된 압축기용 흡입머플러에 관한 것이다. The present invention relates to a compressor suction muffler, and more particularly to a compressor suction muffler provided to improve the flow path structure to reduce the flow loss and noise of the refrigerant more effectively.

일반적으로 냉장고나 공기조화기의 냉동사이클에는 냉매를 압축하도록 밀폐형으로 마련되는 압축기가 채용되며, 이러한 압축기의 밀폐용기 내부에는 냉매의 압축작용을 수행하는 압축유닛으로써, 압축실을 형성하는 실린더와, 피스톤과 같이 압축실 내부에서 압축작용을 수행하는 압축부재와, 압축실을 밀폐시키도록 실린더 일단에 결합되는 실린더헤드가 설치된다. In general, a refrigeration cycle of a refrigerator or an air conditioner employs a compressor provided in a closed type to compress a refrigerant. A cylinder for forming a compression chamber as a compression unit for compressing a refrigerant inside the sealed container of the compressor, A compression member that performs a compression action in the compression chamber, such as a piston, and a cylinder head coupled to one end of the cylinder to seal the compression chamber is installed.

실린더헤드 내부는 외부로부터 밀폐용기 내부로 유입된 냉매를 상기 압축실로 안내하는 냉매흡입방과, 압축실에서 압축되어 토출된 냉매를 밀폐용기 외부로 안내하는 냉매토출방이 상호 구획되도록 마련되고, 이러한 실린더와 실린더헤드 사이에는 냉매흡입방으로부터 압축실로 흡입되거나 압축실로부터 압축되어 냉매토출방으로 토출되는 냉매의 흐름을 단속하기 위한 밸브장치가 개재된다. The inside of the cylinder head is provided such that a refrigerant suction chamber for guiding the refrigerant introduced into the sealed container from the outside into the compression chamber and a refrigerant discharge chamber for guiding the refrigerant compressed and discharged from the compression chamber to the outside of the sealed container are provided so as to partition each other. A valve device is interposed between the cylinder heads to intercept the flow of the refrigerant sucked into the compression chamber from the refrigerant suction chamber or compressed from the compression chamber and discharged to the refrigerant discharge chamber.

따라서 이러한 구성을 갖는 압축실 내부 압축부재가 동작되면, 흡입관을 따 라 밀폐용기 내부로 안내된 냉매는 상기 냉매흡입방을 거쳐 압축실로 흡입되어 압축되고, 압축실에 압축되어 토출되는 냉매는 상기 냉매토출방을 거쳐 토출관으로 안내되며, 이와 같은 작용이 반복적으로 수행되면서 압축기에 의한 냉매의 압축작용이 이루어진다. Therefore, when the compression member inside the compression chamber having such a configuration is operated, the refrigerant guided into the sealed container along the suction pipe is sucked into the compression chamber through the refrigerant suction chamber and compressed, and the refrigerant compressed and discharged into the compression chamber is the refrigerant. Guided to the discharge tube through the discharge chamber, and the same operation is repeatedly performed to compress the refrigerant by the compressor.

한편, 상기 실린더헤드에는 흡입관을 통해 밀폐용기 내부로 안내된 냉매를 상기 냉매흡입방으로 안내함과 동시에 냉매의 소음을 저감시키기 위한 흡입머플러가 연결된다. On the other hand, the cylinder head is connected to the suction muffler for guiding the refrigerant guided into the sealed container through the suction pipe to the refrigerant suction chamber and at the same time reducing the noise of the refrigerant.

도 1에는 이러한 종래 흡입머플러의 구조가 도시된다. Figure 1 shows the structure of such a conventional suction muffler.

도 1에 도시된 바와 같이, 종래 흡입머플러는 통상 일측과 타측에 냉매흡입구(1a)와 냉매토출구를 구비하는 하우징(1)과, 하우징(1) 내부에 설치되는 배플(4)을 구비하며, 이러한 하우징(1)과 배플(4)은 대부분 사출물로 마련된다. As shown in FIG. 1, a conventional suction muffler generally includes a housing 1 having a refrigerant inlet 1a and a refrigerant discharge port on one side and the other side, and a baffle 4 installed inside the housing 1. The housing 1 and the baffle 4 are mostly provided by injection molding.

하우징(1)은 상기 냉매토출구가(1b) 상기 실린더헤드의 냉매흡입방에 삽입되도록 마련된 베이스(3)와, 상기 냉매흡입구(1a)를 일측에 구비하여 상기 베이스(3)와 상호 결합되도록 마련된 바디(2)를 통해 형성된다. The housing 1 includes a base 3 provided with the refrigerant discharge port 1b inserted into the refrigerant suction chamber of the cylinder head, and a refrigerant suction hole 1a provided at one side thereof so as to be mutually coupled with the base 3. It is formed through the body (2).

그리고 상기 배플(4)은 이러한 베이스(3)와 바디(2) 사이의 내부에 설치되어 하우징(1) 내부에 복수의 소음저감실(5.6.7)이 형성되도록 하면서 냉매흡입구(1a)로 유입된 냉매가 이러한 복수의 소음저감실(5,6,7)을 순차적으로 거쳐 상기 냉매토출구(1b)로 안내되도록 하는데, 이러한 배플(4)은 복수개의 소음저감실(5,6,7)을 형성하기 위한 복수개의 격벽(4a,4b)과, 상기 냉매흡입구(1a) 및 냉매토출구(1b)와 각 소음저감실(5,6,7)을 연통시키는 복수개의 관부(4c,4d)와 상기 냉매흡입구(1a) 에 삽입되어 연결되는 삽입부(4e)를 일체로 구비한다. In addition, the baffle 4 is installed between the base 3 and the body 2 so that a plurality of noise reduction chambers 5.6.7 are formed in the housing 1 and flows into the refrigerant inlet 1a. Coolant is sequentially guided through the plurality of noise reduction chambers 5, 6, and 7 to the refrigerant discharge port 1b. The baffle 4 is provided with a plurality of noise reduction chambers 5, 6, and 7; A plurality of pipe portions 4c and 4d for communicating with a plurality of partition walls 4a and 4b for forming, the refrigerant inlet port 1a and the refrigerant discharge port 1b, and the noise reduction chambers 5, 6 and 7, respectively. It is integrally provided with an insertion portion 4e that is inserted into and connected to the refrigerant suction opening 1a.

상기 소음저감실(5,6,7)은 통상 가장 큰 체적을 구비하는 하나의 메인소음저감실(6)과, 메인소음저감실(6)보다 작은 체적을 갖는 다수개의 보조소음저감실(5,7)을 구비하며, 상기 관부(4c,4d)는 상기 냉매흡입구(1a)를 통해 하우징(1) 내부로 안내된 냉매를 상기 메인소음저감실(6)로 안내하는 제1관부(4c)와, 상기 메인소음저감실(6)의 냉매를 상기 냉매토출구(1b) 쪽으로 안내하는 제2관부(4d)를 포함한다. The noise reduction chambers 5, 6 and 7 are usually one main noise reduction chamber 6 having the largest volume and a plurality of auxiliary noise reduction chambers 5 having a smaller volume than the main noise reduction chamber 6. And 7), wherein the pipe portions 4c and 4d are first pipe portions 4c for guiding the refrigerant guided into the housing 1 through the refrigerant suction opening 1a to the main noise reduction chamber 6. And a second pipe portion 4d for guiding the refrigerant in the main noise reduction chamber 6 toward the refrigerant discharge port 1b.

따라서 상기 냉매흡입구(1a)를 통해 하우징(1) 내부로 유입된 냉매는 상기 보조소음저감실(5)과 제1관부(4c)를 거쳐 메인소음저감실(6)로 안내된 후 다시 상기 제2관부(4d)를 통해 보조소음저감실(7)을 거쳐 상기 냉매토출구(1b)로 안내된 상태에서 실린더헤드의 냉매흡입방으로 안내된다. 그리고 상기 밸브장치 쪽에서 냉매를 단속하는 과정에서 발생하는 소음은 이러한 냉매의 흐름방향과 역방향으로 안내된다. (참고로 도 1에 있어서 실신화살표는 냉매의 흐름방향을 나타내고, 점선화살표는 소음의 흐름방향을 나타낸다.)Therefore, the refrigerant introduced into the housing 1 through the refrigerant inlet 1a is guided to the main noise reduction chamber 6 through the auxiliary noise reduction chamber 5 and the first pipe portion 4c, and then again. It is guided to the refrigerant suction chamber of the cylinder head in the state guided through the auxiliary noise reduction chamber 7 through the two pipe parts 4d to the refrigerant discharge port 1b. And the noise generated in the process of interrupting the refrigerant in the valve device is guided in the reverse direction to the flow direction of the refrigerant. (In Fig. 1, the synchro arrow indicates the flow direction of the refrigerant, and the dotted arrow indicates the flow direction of the noise.)

그러나 이러한 종래 압축기용 흡입머플러는 도면에 도시된 바와 같이, 상기 제1관부(4c)의 출구단과 제2관부(4d)의 입구단이 상호 완전히 분리되어 있기 때문에, 제1관부(4c)를 따라 안내되는 냉매가 일단 모두 메인소음저감실(6) 내부로 확산된 상태에서 다시 제2관부(4d)로 안내되도록 하는 구조를 갖기 때문에, 냉매의 유동손실이 커지게 되면서 압축기의 압축효율을 저하시키게 된다. However, in the conventional compressor suction muffler, as shown in the drawing, since the outlet end of the first pipe part 4c and the inlet end of the second pipe part 4d are completely separated from each other, the suction pipe muffler is provided along the first pipe part 4c. Since the refrigerant to be guided once has all been diffused into the main noise reduction chamber 6, the refrigerant is guided back to the second pipe portion 4d. As a result, the flow loss of the refrigerant increases, thereby reducing the compression efficiency of the compressor. do.

또 이때는 냉매의 흐름방향과 역방향으로 안내되는 소음 측면에서 보더라도 상기 메인소음저감실(6)이 단순한 확장형 공간을 형성하고 있기 때문에, 밸브장치 쪽에서 발생하는 소음을 저감시키는데도 한계가 있었다. In this case, the main noise reduction chamber 6 also has a limitation in reducing the noise generated from the valve device side, even in view of the noise guided in the opposite direction to the flow direction of the refrigerant.

본 발명은 이와 같은 문제점을 해결하기 위한 것으로, 이러한 본 발명의 목적은 내부 유로구조를 개선하여 냉매의 유동손실 및 소음을 보다 효과적으로 줄일 수 있도록 마련된 압축기용 흡입머플러를 제공하는 것이다.The present invention is to solve such a problem, it is an object of the present invention to provide a suction muffler for the compressor provided to more effectively reduce the flow loss and noise of the refrigerant by improving the internal flow path structure.

The pipe parts 93 and 94 may include a first pipe part 93 for guiding the refrigerant introduced into the first auxiliary noise reduction room 110 to the main noise reduction room 120, and a main noise reduction room 120. The second pipe part 94 for communicating between the second auxiliary noise reduction chamber 130 and the first pipe portion 93 and the second pipe portion 94 are connected to the main noise reduction chamber 120 in the middle.

이중 상기 제3관부(100)는 제1관부(93)를 통해 메인소음저감실(120)로 안내된 냉매가 메인소음저감실(120) 내부로 확산됨이 없이 바로 상기 제2관부(94)로 안내될 수 있도록 함으로써, 냉매토출구(52)로 안내되는 냉매의 유동손실을 저감시키켜, 냉매의 유동손실 과다로 인한 압축기의 압축효율 저하를 방지하게 된다. The third pipe part 100 is the second pipe part 94 without the refrigerant guided to the main noise reduction room 120 through the first pipe part 93 into the main noise reduction room 120.

즉, 상기 제3관부(100)가 마련된 상태에서는 도 3에 실선화살표로 나타낸 바와 같이, 상기 냉매흡입구(51)를 통해 흡입머플러(13) 내부로 유입된 냉매가 제1보 조소음저감실(110)-제1관부(93)-제2관부(94)-제2보조소음저감실(130)-냉매토출구(52) 순으로 흡입머플러(13) 내부를 통과하게 되고, 제1관부(93)에서 제2관부(94)로 안내되는 과정에서 소량의 냉매만이 상기 연통공(121)을 통해 메인소음저감실(120)로 빠져나갔다가 제2관부(94)로 회수되므로, 가장 체적이 큰 매인소음저감실(120)에서 냉매의 확산이 억제되면서 냉매의 유동손실을 크게 줄일 수 있게 되는 것이다. That is, in the state in which the third pipe part 100 is provided, as shown by the solid arrow in FIG. 3, the refrigerant introduced into the suction muffler 13 through the refrigerant suction port 51 is the first auxiliary noise reduction chamber ( 110)-First pipe part (93)-Second pipe part (94)-Second auxiliary noise reduction chamber (130)-The refrigerant discharge port (52) in order to pass through the inside of the suction muffler (13), and the first pipe part (93) In the process of being guided to the second pipe portion 94) only a small amount of refrigerant exits the main noise reduction chamber 120 through the communication hole 121 and is recovered to the second pipe portion 94, so that the volume As the diffusion of the refrigerant is suppressed in the large main noise reduction chamber 120, the flow loss of the refrigerant can be greatly reduced.

In addition, the opening and closing noise generated during opening and closing of the discharge valve 25b and the suction valve 25a in the valve device 25 acts in the opposite direction to the flow direction of the refrigerant, as indicated by the dotted arrows in FIG. 3. In the state where the three pipe part 100 is formed, since the main noise reduction chamber 120 is utilized as a resonance space instead of a simple ring expansion space, the noise reduction effect by the suction muffler 13 can be further improved.
