냉동 설비용 어큐무레이터의 구조{Structure of accumulator for cold equipment}Structure of accumulator for cold equipment

본 고안은 룸 에어컨디셔너, 냉장고용의 로터리식 컴푸레서에 있어서, 냉매가스 흡입구쪽에 부착되어 증발기를 통하여 진입하는 냉매가스 중 미처 기화하지 못한 냉매액을 배플막을 통하여 걸러주면서 기체화되도록 하는 냉동설비용 어큐무레이터에 관한 것으로, 더욱 상세히는 강철재로 된 몸체측에 동재로 된 커넥팅튜브및 벤트튜브를 끼워 일체화로 용접접합함에 있어 용접이 보다 확실하게 되도록 하기 위하여 개선된 커넥터 튜브와 벤트튜브를 제공하며 이와같이 개선된 튜브를 몸체측에 접속시키므로서 제품의 중요한 요소인 기밀성 향상, 신뢰성 및 품질향상을 가져올 수 있도록 함에 있다.The present invention is a rotary compressor for a room air conditioner and a refrigerator, which is attached to the refrigerant gas inlet port and filters the refrigerant liquid that has not vaporized from the refrigerant gas entering through the evaporator through a baffle membrane to vaporize. The present invention relates to a cumulator, and more particularly, to an improved connector tube and a vent tube, in order to make welding more reliable in integral welding by fitting a connecting tube and a vent tube of copper material on a steel body side. By connecting the improved tube to the body side, it is possible to bring about improved airtightness, reliability and quality, which are important elements of the product.

일반적으로 로터리식 컴푸레서에 있어서의 어큐무레이터는 매우 중요한 핵심부품으로 기본적으로 도 4 와 같이 구성되어 있다.In general, the accumulator in a rotary compressor is a very important core component and is basically configured as shown in FIG. 4.

즉, 몸체(1)는 원통형으로 되고 몸체(1) 양측의 축관부(2a)(2b)에는 커넥팅튜브(3a)와 벤트튜브(3b)가 끼워져 결합되고 기밀을 위하여 이들의 접속부에는 용접을 행하고 있는데, 상기 각 튜브(3a)(3b)는 각각 2개소가 용접(2점용접)되어 몸체(1)측에 결합되고 있다.That is, the body 1 is cylindrical and the connecting tube 3a and the vent tube 3b are fitted to the shaft tube parts 2a and 2b on both sides of the body 1, and the welding parts are welded to the connecting parts for airtightness. Each of the tubes 3a and 3b is welded (two-point welded) to the body 1 side.

한편, 어큐무레이터는 내부가 높은 팽창압이 발생하므로 기밀 유지가 중요한 것으로 용접이 매우 중요한 요소로 작용한다.On the other hand, since the accumulator has a high expansion pressure inside, airtightness is important and welding is a very important factor.

또한 벤트 튜브(3b)가 몸체(1)측에 끼워짐에 있어서는 상당한 길이가 내부로 끼워져야 하는데 외부에서는 끼워진 상태를 육안으로 확인 할 수 없으므로 신뢰성이 없을 뿐만 아니라, 용접 접합시 벤트 튜브(3b)가 수직방향으로만 서로 면이 맞닿아 용접이 되므로 옆으로 휘어진 상태로 끼워져 결합되는 문제점등이 따랐던 것이다.In addition, when the vent tube 3b is fitted to the body 1 side, a considerable length must be fitted inside, and since it is impossible to visually check the fitted state from the outside, it is not reliable, and the vent tube 3b at the time of welding welding Since the surfaces are in contact with each other only in the vertical direction is welded to the side bent in a state that is coupled to the problem was accompanied.

한편 몸체(1)와 튜브(3a)(3b)가 공히 동재로 된 어큐무레이터의 경우 원가의 상승요인을 불러오기 때문에 이를 해소시키기 위하여 본 출원인은 몸체(1)는 가격이 저렴한 강철 파이프로 구성하고 양측 튜브(3a)(3b)는 가공성을 고려하여 동재를 사용하므로서 원가 절감과 소음발생을 최소화시킬 수 있도록 실용신안출원 제 97-14583호로 개선된 구조의 어큐무레이터를 제안한 바 있는데, 이는 몸체(1)와 튜브(3a)(3b)가 서로 용융점이 이질재료여서 용접이 까다로왔던 것이다.Meanwhile, in order to solve this problem, the accumulator in which the body 1 and the tubes 3a and 3b are all made of copper is used. Therefore, in order to solve the problem, the applicant body 1 is made of a low-cost steel pipe. In addition, both tubes (3a) and (3b) proposed an accumulator with improved structure in Utility Model Application No. 97-14583 to minimize cost and noise by using copper materials in consideration of workability. (1) and the tubes (3a) and (3b) are different from each other because the melting point is different from each other, which makes welding difficult.

본 고안은 몸체 양측에 끼워져 용접되는 커넥팅 튜브및 벤트 튜브를 보다 합리적이고 양호하게 몸체측에 끼워져 결합되도록 개선하고, 동시에 용접이 양호하여 기밀성과 신뢰성이 있는 어큐무레이터를 제공하고자 한 것으로 , 이하 그 구성 및 작용효과를 첨부된 도면을 토대로 하여 상세히 설명한다.The present invention is to improve the connecting tube and the vent tube to be inserted and welded on both sides of the body to be more reasonably and better fitted and coupled to the body side, and at the same time to provide an accumulator with good airtightness and reliability by welding is good, The configuration and the effect will be described in detail with reference to the accompanying drawings.

이하, 종래 구조와 동일 부분에 대하여는 편의상 동일 부호를 붙여 설명한다.Hereinafter, the same parts as the conventional structures will be described with the same reference numerals for convenience.

강철 파이프로 된 몸체(1)의 양측 축관부(2a)(2b)에 동재로 된 커넥팅튜브(3a)와 벤트튜브(3b)를 끼워 일체화가 되도록 용접시킨 어큐무레이터에 있어서, 상기 커넥팅 튜브(3a)와 벤트 튜브(3b)는 삽입기점이 되는 부위에 튜브(3a)(3b)의 직경보다 큰 띠형상의 주름부(4a)(4b)를 형성하여 상기 튜브(3a)(3b)가 주름부(4a)(4b)를 기점으로 하여 몸체(1)측에 끼워지도록 하므로서 삽입치수가 미리 설정되도록 하고, 상기 각 튜브(3a)(3b)가 끼워지는 몸체(1)양측 축관부(2a)(2b)의 끝부 내면은 축관부(2a)(2b)의 내경보다 크게 용접 공간(5)을 형성한다.In the accumulator in which the connecting tube 3a and the vent tube 3b made of copper material are inserted and welded to both shaft pipe parts 2a and 2b of the body 1 made of steel pipe, the connecting tube ( 3a) and the vent tube 3b form band-shaped corrugations 4a, 4b larger than the diameters of the tubes 3a, 3b at the insertion starting point, and thus the tubes 3a, 3b are corrugated. The insertion dimensions are set in advance by fitting the parts 4a and 4b on the body 1 side, and the shafts 2a on both sides of the body 1 into which the respective tubes 3a and 3b are fitted. The inner surface of the end of (2b) forms the welding space 5 larger than the inner diameter of the shaft pipe part 2a (2b).

한편, 벤트튜브(3b)는 삽입부분이 길기 때문에 몸체(1)의 축관부(2b)에 끼워져 결합되거나 용접될 때 미세하게 움직여 비틀어 질수 있기 때문에 바람직스럽게는 축관부(2b)와 접촉되는 접속부를 직경이 크도록 확관시켜 움직임을 최소화 시키는 것이 좋다.On the other hand, since the vent tube 3b has a long insertion portion, the vent tube 3b is inserted into the shaft tube portion 2b of the body 1 and can be twisted finely when being joined or welded. It is good to expand the diameter to minimize the movement.

이와같이 구성된 본 고안의 어큐무레이터는 몸체(1)의 양측 축관부(2a)(2b) 에 끼워져 결합되는 커넥팅 튜브(3a)및 벤트 튜브(3b)는 삽입부를 축관부(2a)(2b)에 삽입시 주름부(4a)(4b)에 의해 미리 삽입 길이가 결정되어 있으므로 특별히 삽입길이를 확인하지 않고 주름부(4a)(4b)의 일측끝벽이 몸체(1)의 일측벽과 맞닿을 때까지 삽입하면 되는 것으로 삽입작업이 편리하다.The accumulator of the present invention configured as described above has a connecting tube 3a and a vent tube 3b which are fitted to and coupled to both shaft tubes 2a and 2b of the body 1, and the insertion tube is connected to the shaft tubes 2a and 2b. Since the insertion length is determined in advance by the pleats 4a and 4b at the time of insertion, the end length of one side of the pleats 4a and 4b is in contact with the one side wall of the body 1 without checking the insertion length. It is easy to insert by inserting.

또한, 각 튜브(3a)(3b)를 몸체(1)의 축관부(2a)(2b)에 용접 접합하기 위해서는 미리 작업자가 몸체(1)의 축관부(2a)(2b)측에 튜브(3a)(3b)를 삽입시킴과 동시에 이들 접촉부에 용접을 위한 용접재를 넣은 후 고온상태의 로내에 투입하게 되면 (실제 제작에 있어서는 컨베어 벨트를 통해 로내로 투입됨)로내에서 발생하는 고열에 의해 용접재는 용융되므로서 몸체(1)와 튜브(3a)(3b)는 일체화로 용융접합되는 것이다. 특히 본 고안에 있어서는 용접 공간(5)이 형성되어 있으므로 용접에 따른 기밀성이 더욱 확보되는 것이며, 특히 용접부위가 수직 방향과 좌우방향으로 보강되므로 기밀성이 향상된다. 또한 상기 각 튜브(3a(3b)가 몸체측에 끼워짐에 있어서 주름부(4a)(4b)가 몸체(1)의 끝부와 서로 맞닿아 끼워지므로 튜브(3a)(3b)가 비틀어짐이 없이 정확히 끼워지는 것이다.In addition, in order to weld-join each tube 3a, 3b to the shaft tube part 2a, 2b of the body 1, an operator advances the tube 3a in the shaft tube part 2a, 2b side of the body 1 beforehand. (3b) and at the same time insert the welding material for welding into these contacts and insert it into the furnace at high temperature (in actual production, it is fed into the furnace through the conveyor belt). As the ash is melted, the body 1 and the tubes 3a and 3b are melt-bonded in an integrated manner. In particular, in the present invention, since the welding space 5 is formed, the airtightness according to welding is further secured. In particular, since the welded area is reinforced in the vertical direction and the left and right directions, the airtightness is improved. In addition, since each of the tubes 3a (3b) is fitted to the body side, the corrugations 4a, 4b are fitted in contact with the end of the body 1, so that the tubes 3a, 3b are not twisted. It is fitted correctly.

이상 살펴본 바와같이, 본 고안은 몸체의 양측에 끼워져 일체화로 용접되는 커넥팅 튜브 및 벤트 튜브에 삽입길이에 맞는 위치에 주름부를 형성하여 삽입길이가 주름부에 의해 결정되므로 삽입에 따른 작업성이 향상됨과 동시에 삽입길이가 육안으로 확인되므로 제품의 신뢰성이 향상되며, 또한 용접에 있어서 주름부와 축관부끝벽이 접합되고 동시에 넓은 용접공간(5)에 의해 접합되므로 어큐무레이터의 중요한 요소인 기밀성이 확보되는 것이다.As described above, the present invention is formed in the connecting tube and the vent tube welded integrally welded on both sides of the body to form a pleat in the position corresponding to the insertion length, the insertion length is determined by the pleat, thereby improving workability according to the insertion and At the same time, the insertion length is visually confirmed, which improves the reliability of the product. Also, in the welding, the crimp part and the shaft tube end wall are joined together, and at the same time, they are joined by the wide welding space 5, thereby ensuring the airtightness, which is an important element of the accumulator. will be.
