본 발명은 냉장고의 소음저감형 어큐뮬레이터에 관한 것으로서, 보다 상세하 게는 냉장고의 어큐뮬레이터에서 유입측 회수관의 속도와 저항을 최대한 줄이면서 냉매를 분사함으로써 이 부분에서 발생하는 소음을 크게 저감할 수 있는 냉장고의 소음저감형 어큐뮬레이터에 관한 것이다.The present invention relates to a noise reduction accumulator of a refrigerator, and more particularly, by injecting a refrigerant while reducing the speed and resistance of an inlet return pipe in an accumulator of a refrigerator as much as possible, noise generated in this part can be greatly reduced. It relates to a noise reduction accumulator of a refrigerator.

일반적으로, 냉장고는 냉매를 고온고압으로 압축시키는 압축기와, 압축기로부터 보내진 냉매를 방열하여 저온고압상태의 액상냉매로 변환시키는 응축기와, 응축기를 통과한 저온고압상태의 냉매가 통과되면서 저온저압의 액상냉매로 변환시키는 모세관과, 모세관을 통해 저온저압상태로 보내지는 냉매를 냉장고 내의 공기와 열교환되게 하여 기체상태로 변환시키는 증발기로 구성된다. 이때, 증발기와 압축기 사이에는 회수관이 연결되어 있어, 증발기에서 기체상태로 변환된 냉매가 일단 상기 회수관을 통해 압축기로 회수된 후 다시 고온고압으로 압축된다.In general, a refrigerator includes a compressor for compressing a refrigerant at a high temperature and high pressure, a condenser for dissipating the refrigerant sent from the compressor and converting the refrigerant into a liquid refrigerant at a low temperature and high pressure state, and a low temperature and low pressure liquid phase as the refrigerant passes through the condenser. A capillary tube for converting into a refrigerant and an evaporator for converting the refrigerant, which is sent to the low temperature and low pressure state through the capillary, into a gas state by causing heat exchange with the air in the refrigerator. At this time, a recovery tube is connected between the evaporator and the compressor, so that the refrigerant converted into the gas state in the evaporator is once recovered to the compressor through the recovery tube and then compressed to high temperature and high pressure.

그런데, 압축기로 회수되는 냉매에는 미처 기체상태로 변환되지 못한 액상냉매가 포함되어 있다. 이러한 액상냉매가 압축기로 회수되면 압축효율이 저하되고 결국 냉기효율이 떨어지는 요인이 된다.However, the refrigerant recovered by the compressor includes a liquid refrigerant that could not be converted into a gaseous state. When the liquid refrigerant is recovered by the compressor, the compression efficiency is lowered, and thus, the cold air efficiency is lowered.

따라서, 증발기와 압축기 사이에는 기액상태의 냉매를 명확히 분리하는 어큐뮬레이터가 설치된다.Therefore, an accumulator is provided between the evaporator and the compressor to clearly separate the refrigerant in the gas liquid state.

이러한 기능을 가지는 일반적인 어큐뮬레이터의 설치상태 및 그 내부 구조가 에 한국공개실용신안공보 제1998-0141767호(이하, '종래기술'이라 한다)에 개시되어 있는데, 도 1에 도시된 바와 같이, 내부로 확장된 공간을 가지는 확장관(32)과, 상기 확장관(32)의 하부에서 상부로 통과한 회수관(41)(42)으로 구성된다.The installation state and the internal structure of a general accumulator having such a function are disclosed in Korean Unexamined Utility Model Publication No. 1998-0141767 (hereinafter referred to as 'prior art'), as shown in FIG. It consists of an expansion pipe 32 having an expanded space, and recovery pipes 41 and 42 passed from the lower portion of the expansion pipe 32 to the upper portion.

그러나, 이와 같은 종래기술에 따르면, 집중 냉매분사방식을 택하고 있기 때 문에, 유입측 회수관(41)을 통해 유입되는 냉매는 고속으로 확장관(32)의 내벽면에 충돌할 수밖에 없었다. 이에 따라, 어큐뮬레이터에서 발생하는 소음이 커지게 되었고 소비자에게 불편함을 주게 되었다.However, according to this conventional technology, since the concentrated refrigerant injection method is adopted, the refrigerant flowing through the inflow-side recovery pipe 41 has no choice but to collide with the inner wall surface of the expansion pipe 32 at high speed. As a result, the noise generated by the accumulator is increased and it is inconvenient for the consumer.

더욱이, 유입측 회수관(41)을 통해 나가는 냉매 입자는 확장관의 내벽면 중 국소부위에만 충돌하기 때문에 확장관(32)의 내벽면 충돌시 그 충격량이 커지므로 소음은 더욱 크게 되었다.In addition, since the refrigerant particles exiting through the inflow-side recovery pipe 41 collide only with a local portion of the inner wall surface of the expansion pipe, the impact amount becomes larger when the inner wall surface of the expansion pipe 32 collides, and the noise is further increased.

본 발명은 전술한 문제점을 해결하기 위해 안출된 것으로서, 본 발명의 목적은 냉매를 최대한 분산시켜서 유입시킴으로써 확장관의 내벽면 충돌시의 소음을 크게 저감시킬 수 있는 냉장고의 소음저감형 어큐뮬레이터를 제공하는데 있다.The present invention has been made to solve the above problems, an object of the present invention is to provide a noise reduction accumulator of the refrigerator that can greatly reduce the noise during collision of the inner wall surface of the expansion pipe by dispersing the refrigerant to the maximum. have.

또한, 본 발명의 다른 목적은 어큐뮬레이터로 유입되는 냉매입자의 속도를 낮추어 확장관의 내벽면 충돌시의 소음을 크게 저감시킬 수 있는 냉장고의 소음저감형 어큐뮬레이터를 제공하는데 있다.In addition, another object of the present invention is to provide a noise reduction accumulator of a refrigerator capable of greatly reducing the noise during collision of the inner wall of the expansion pipe by lowering the speed of the refrigerant particles flowing into the accumulator.

전술한 목적을 달성하기 위해, 본 발명에 따른 냉장고의 소음저감형 어큐뮬레이터는, 냉장고의 증발기와 압축기 사이에 배치되는 것으로, 내부에 확장된 공간을 가지는 확장관, 상기 확장관 내부의 하부에서 상부로 연장되는 유입측 회수관, 상기 확장관의 상부에 형성된 유출측 파이프, 및 상기 유입측 회수관의 개구에는 점차 확대되는 단면을 가지는 분산관을 포함하는 것을 특징으로 한다.In order to achieve the above object, the noise reduction accumulator of the refrigerator according to the present invention, which is disposed between the evaporator and the compressor of the refrigerator, an expansion pipe having an expanded space therein, from bottom to top of the inside of the expansion pipe The inlet side recovery pipe extending, the outlet side pipe formed on the upper portion of the expansion pipe, and the opening of the inlet side recovery pipe is characterized in that it comprises a distribution pipe having a gradually expanding cross section.

여기서, 상기 분산관은 테이퍼 모양으로 확장되는 것이 바람직하다.Here, the dispersion tube is preferably extended in the tapered shape.

또한, 상기 유입측 회수관은 분산관쪽의 중도부가 상기 확장관의 내벽면을 향해 절곡되어 있는 것이 바람직하다.In addition, it is preferable that the inlet side recovery pipe bend toward the inner wall surface of the expansion pipe toward the middle of the dispersion pipe.

또한, 상기 분산관에는 그물망이 설치되어 있는 것이 바람직하다.Moreover, it is preferable that the net is provided in the said dispersion pipe.

이하, 첨부된 도 3을 참조하여 본 발명의 바람직한 일 실시예를 상세히 설명한다. 이 경우, 어큐뮬레이터를 제외한 다른 부분은 일반적인 냉장고와 다르지 않으므로 그 부분에 대한 별도의 설명은 생략하도록 한다.Hereinafter, with reference to the accompanying Figure 3 will be described a preferred embodiment of the present invention; In this case, other parts except the accumulator are not different from the general refrigerator, and thus a separate description thereof is omitted.

도시된 바와 같이, 본 발명에 따른 냉장고의 소음저감형 어큐뮬레이터(1000)는, 냉장고의 증발기와 압축기 사이에 배치되는 것으로, 내부에 확장된 공간을 가지는 확장관(100)과, 상기 확장관(100) 내부의 하부에서 상부로 연장되는 유입측 회수관(200)과, 상기 확장관(100)의 상부에 형성된 유출측 파이프(300)로 구성된다.As illustrated, the noise reduction accumulator 1000 of the refrigerator according to the present invention is disposed between the evaporator and the compressor of the refrigerator, and has an expansion pipe 100 having an extended space therein and the expansion pipe 100. An inlet-side recovery pipe 200 extending from the lower part of the inside to the upper part, and the outlet-side pipe 300 formed on the upper part of the expansion pipe 100.

여기서, 상기 유입측 회수관(200)의 개구에는 점차 확대되는 단면을 가지는 분산관(400)이 형성되어 있어, 어큐뮬레이터(1000) 내부로 유입되는 냉매를 넓게 분산시킴으로써 확장관(100)의 내벽면에 가해지는 충격량과 이로 인한 소음을 크게 줄일 수 있다.Here, the distribution pipe 400 having a gradually expanding cross section is formed in the opening of the inlet-side recovery pipe 200, the inner wall surface of the expansion pipe 100 by dispersing the refrigerant flowing into the accumulator 1000 widely The amount of impact applied and the resulting noise can be greatly reduced.

도시된 바와 같이, 상기 분산관(400)은 테이퍼 모양으로 확장되는 것이 바람 직하지만 나팔형으로 확장될 수도 있다.As shown, the dispersion pipe 400 is preferably expanded in a tapered shape, but may be expanded in a trumpet shape.

또한, 상기 유입측 회수관(200)은 분산관(400) 쪽의 중도부가 상기 확장관(100)의 내벽면을 향해 절곡되어 있어, 냉매 역류시 유입측 회수관(200)으로 직접 냉매가 침입하는 것을 방지할 수 있다.In addition, the inlet side recovery pipe 200 is bent toward the inner wall surface of the expansion pipe 100 in the middle portion of the distribution pipe 400 side, the refrigerant flows directly into the inlet recovery pipe 200 during the reflux flow back Can be prevented.

한편, 상기 분산관(400)에는 그 개구에 그물망(500)이 설치되어 있다. 이에 따라, 어큐뮬레이터(1000) 내부로 유입되는 냉매의 속도를 1차적으로 줄임으로써 어큐뮬레이터(1000)의 확장관(100) 내면에 충돌하는 소음을 현저하게 줄일 수 있다.On the other hand, the dispersion pipe 400 is provided with a net 500 in the opening. Accordingly, by primarily reducing the speed of the refrigerant flowing into the accumulator 1000, the noise that collides with the inner surface of the expansion tube 100 of the accumulator 1000 may be significantly reduced.

이 경우, 상기 그물망(500)은 분산관(400) 개구의 선단 또는 약간 들어간 위치에서 배치될 수 있다.In this case, the mesh 500 may be disposed at the tip of the opening of the dispersion pipe 400 or slightly entered.

이에 따라, 상기 어큐뮬레이터(1000)에 의해 회수되는 냉매는 먼저 확장관(100)의 하부에 연결된 유입측 회수관(200)을 통해 그 내부로 유입된다. 그리고, 유입되는 냉매는 유입측 회수관(200)의 단부로부터 토출되어 확장관(100)의 내부로 나오게 된다.Accordingly, the refrigerant recovered by the accumulator 1000 is first introduced into the inside through the inlet-side recovery pipe 200 connected to the lower portion of the expansion pipe 100. Then, the introduced refrigerant is discharged from the end of the inlet side recovery pipe 200 and exits into the expansion pipe 100.

전술한 바와 같은 구성의 본 발명에 따르면, 냉장고 어큐뮬레이터의 유입측 회수관의 개구에는 점차 확대되는 단면을 가지는 분산관이 형성되어 있어 냉매를 최대한 분산시켜서 유입시킴으로써 확장관의 내벽면 충돌시의 소음을 크게 저감시킬 수 있다.According to the present invention having the above-described configuration, the opening of the inlet side return pipe of the refrigerator accumulator is formed with a distribution tube having a gradually enlarged cross section so as to disperse the refrigerant as much as possible to introduce noise in the collision of the inner wall surface of the expansion pipe. It can greatly reduce.

또한, 본 발명에 따르면, 상기 분산관에는 그물망이 설치되어 있으므로 어큐뮬레이터로 유입되는 냉매입자의 속도를 낮추어 확장관의 내벽면 충돌시의 소음을 크게 저감시킬 수 있다.Further, according to the present invention, since the net is installed in the dispersion pipe, the noise of the inner wall surface of the expansion pipe can be greatly reduced by lowering the speed of the refrigerant particles flowing into the accumulator.
