로타리 컴프레서용 트윈 벤트튜브 타입 일체형 철제 어큐무레이터{TWIN BENT TUBE TYPE 1-PIECE STEEL ACCUMULATOR FOR ROTARY COMPRESSOR}Twin vent tube type integral steel accumulator for rotary compressor {TWIN BENT TUBE TYPE 1-PIECE STEEL ACCUMULATOR FOR ROTARY COMPRESSOR}

본 고안은 룸 에어컨디셔너의 로타리 컴프레서용 어큐무레이터(Rotary Compressor Accumulator)에 있어서, 2개의 벤트튜브를 장착한 트윈 벤트튜브 타입 일체형 철제 어큐무레이터에 관한 것으로, 철판을 딥 드로잉한 후, 몸체의 내부에 스크린과 스크린홀더로 이루어진 배플을 장착하고, 상기 몸체의 커넥팅튜브측은 CNC 선반에서 스피닝 가공하여 축관부를 형성하며, 벤트튜브측은 프레스로 피어싱한 후 버링 가공하여 버링부를 형성하여, 상기 축관부의 축관단부와 버링부에 상기 커넥팅튜브 및 벤트튜브를 끼워 넣어 각각 용접, 일체화하되, 상기 벤트튜브를 철제 파이프와 동제 파이프로 구성한 것을 특징으로 한 것이다.The present invention is a rotary compressor accumulator for a room air conditioner, and includes a twin vent tube type integrated steel accumulator equipped with two vent tubes. A baffle consisting of a screen and a screen holder is mounted on the connecting tube, and the connecting tube side of the body is spun in a CNC lathe to form a shaft tube, and the vent tube side is pierced by a press to form a burring portion to form a burring portion. The connecting tube and the vent tube are inserted in the burring portion, and welded and integrated, respectively, but the vent tube is composed of an iron pipe and a copper pipe.

본 고안에 따르면, 상부컵과 하부컵을 용접하던 종래의 2피스 접합방식에 있어서의 용접부위를 없애고 1피스 접합방식으로 함으로써, 냉동설비의 핵심인 누설의 위험을 획기적으로 개선함과 동시에, 기존에 고가의 동제 파이프를 사용하던 벤트튜브의 일부를 가격이 저렴한 강철 파이프로 구성함으로써 제조원가를 낮추는 효과가 있다.According to the present invention, by eliminating the welding part in the conventional two-piece joining method of welding the upper cup and the lower cup to the one-piece joining method, the risk of leakage, which is the core of the refrigerating facility, is remarkably improved, and As part of the vent tube, which used expensive copper pipes, is made of steel pipes, which are inexpensive, the manufacturing cost is reduced.

최근, 룸 에어컨디셔너의 대형화, 고급화 추세에 따라, 어큐무레이터의 크기나 용량이 확장되면서 2개의 벤트튜브를 장착한 트윈 벤트튜브 타입 어큐무레이터의 구성이 소개되고 있다.Recently, in accordance with the trend toward larger and more advanced room air conditioners, the configuration of a twin vent tube type accumulator equipped with two vent tubes has been introduced as the accumulator has been enlarged in size and capacity.

예컨대, 도3의 어큐무레이터는, 몸체(1)를 2피스(2 pieces) 접합방식으로 하면서, 한쪽 축관단부(1c)에 커넥팅튜브(2)를 접합하고, 반대쪽 버링부(1d)에는 2개의 벤트튜브(3),(4)를 접합하며, 몸체(1)의 내부에 스크린(5)과 스크린홀더(6)로 이루어진 배플(7)을 갖춘 구성이다.For example, the accumulator of FIG. 3 joins the connecting tube 2 to one shaft end portion 1c while the body 1 is a two-piece joining method, and the two to the opposite burring portion 1d. The two vent tubes 3 and 4 are bonded to each other, and the baffle 7 includes a screen 5 and a screen holder 6 inside the body 1.

상기 어큐무레이터는, 몸체(1)의 중앙부를 2등분 한 상태로서, 철판을 프레스 가공한 후 상부컵(1-1)과 하부컵(1-2)을 강제 압입하여 용접에 의해 접합하는 구성이나, 상부컵(1-1)과 하부컵(1-2)의 용접부(8)에 누설현상이 발생할 가능성이 많고, 벤트튜브(3),(4) 전체가 동제(銅製) 파이프여서 제조원가에 상당한 부담이 되고 있다.The accumulator is a state in which the center portion of the body 1 is divided into two parts, and after press-processing the steel plate, the accumulator is forcibly press-fits the upper cup 1-1 and the lower cup 1-2 to be joined by welding. In addition, there is a high possibility that leakage occurs in the welded portion 8 of the upper cup 1-1 and the lower cup 1-2, and the entire vent tubes 3 and 4 are made of copper pipes. There is considerable burden.

또한, 현재 생산되고 있는 룸 에어컨디셔너의 로타리 컴프레서용 어큐무레이터 중에는, 철제(鐵製) 파이프를 원재료로 하여 CNC 선반에서 로울러를 이용, 스피닝공법으로 양쪽 축관부를 가공하는 방식의 1피스 철제 어큐무레이터가 있으나, 상기한 트윈 벤트튜브 타입 어큐무레이터의 경우에는, 철제 파이프를 이용해서 2개의 벤트튜브를 장착하는 공정이 쉽지 않았다.In addition, the one-piece steel accumulator in which the rotary compressor of the room air conditioner is manufactured by using a roller on a CNC lathe and machining both shaft pipe parts by using a roller on a CNC lathe. However, in the case of the twin vent tube type accumulator described above, the process of mounting two vent tubes using an iron pipe was not easy.

따라서, 본 고안에서는 상기 종래의 결점을 개선하고자 하는 것으로, 철판을 딥 드로잉한 후, 몸체의 내부에 스크린과 스크린홀더로 이루어진 배플을 장착하고, 상기 몸체의 커넥팅튜브측은 CNC 선반에서 스피닝 가공하여 축관부를 형성하며, 벤트튜브측은 프레스로 피어싱한 후 버링 가공하여 버링부를 형성하여, 상기 축관부의 축관단부와 버링부에 상기 커넥팅튜브 및 벤트튜브를 끼워 넣어 각각 용접, 일체화하되, 상기 벤트튜브를 철제 파이프와 동제 파이프로 구성하여, 용접부위를 없애고 1피스 접합방식으로 함으로써, 냉동설비의 핵심인 누설의 위험을 획기적으로 개선함과 동시에, 기존에 고가의 동제 파이프를 사용하던 벤트튜브의 일부를 가격이 저렴한 강철 파이프로 구성함으로써 제조원가를 낮출 수 있는 로타리 컴프레서용 어큐무레이터를 제공하고자 한다.Therefore, in the present invention, to improve the above-mentioned drawbacks, after deep drawing the iron plate, and equipped with a baffle consisting of a screen and a screen holder on the inside of the body, the connecting tube side of the body by spinning on a CNC lathe shaft pipe And forming a burring portion by piercing the vent tube side with a press, and inserting the connecting tube and the vent tube into the shaft tube end portion and the burring portion of the shaft pipe portion, respectively, welding and integrating the vent tube into the steel pipe. It is made of copper pipe, eliminating welding area and making it one piece joining method, which greatly improves the risk of leakage, which is the core of refrigeration equipment, and at the same time reduces the price of a part of the vent tube that used expensive copper pipe. Accumulators for rotary compressors can be manufactured with low cost steel pipes to reduce manufacturing costs It intends to provide.

도1 및 도2는 본 고안의 어큐무레이터의 개략적인 설명도와 그 단면도이다.1 and 2 are schematic explanatory diagrams and cross-sectional views of the accumulator of the present invention.

도면에서, 본 고안의 어큐무레이터는, 철판을 딥 드로잉한 후, 몸체(1)의 내부에 스크린(5)과 스크린홀더(6)로 이루어진 배플(7)을 장착하고, 상기 몸체(1)의 커넥팅튜브(2)측은 CNC 선반에서 스피닝 가공하여 축관부(1a)를 형성하며, 벤트튜브(3),(4)측은 프레스로 피어싱한 후 버링 가공하여 버링부(1d)를 형성하여, 상기 축관부(1a)의 축관단부(1c)와 버링부(1d)를 상기 커넥팅튜브(2) 및 벤트튜브(3),(4)와 각각 용접, 일체화하되, 상기 벤트튜브(3),(4)를 철제 파이프(3s),(4s)와 동제 파이프(3c),(4c)로 구성한 것을 특징으로 한다.In the figure, the accumulator according to the present invention, after deep drawing the iron plate, is equipped with a baffle (7) consisting of a screen (5) and a screen holder (6) inside the body (1), the body (1) The connecting tube (2) side of the spinning process on the CNC lathe to form the shaft tube portion (1a), the vent tubes (3), (4) side pierced by the press and then burring to form a burring portion (1d), the The shaft tube end portion 1c and the burring portion 1d of the shaft tube portion 1a are welded and integrated with the connecting tube 2 and the vent tubes 3 and 4, respectively, but the vent tubes 3 and 4 are integrated. ) Is composed of steel pipes 3s and 4s and copper pipes 3c and 4c.

구체적으로는, 철판을 딥 드로잉하여 한쪽 끝은 막히고 반대쪽은 열려 있는 컵 형상의 몸체(1)를 성형하고, 열려 있는 관의 내부에 배플(7)을 장착한 다음, 상기 몸체(1)의 양단을 가공 성형함에 있어, 상기 몸체(1)의 일단은 CNC 선반에 로울러를 붙여, 스피닝 가공하여 축관단부(1c)를 성형한 다음, 커넥팅튜브(2)를 용접하여 연결하고, 상기 몸체(1)의 막혀 있는 타단은 프레스로 피어싱한 후 버링 가공하여 2개의 벤트튜브를 용접, 결합하도록 구성된다.Specifically, the deep drawing of the iron plate to form a cup-shaped body (1) of which one end is blocked and the other side is open, the baffle (7) is mounted inside the open tube, and then both ends of the body (1) In processing molding, one end of the body (1) is attached to the CNC lathe, spinning to form a shaft tube end (1c), then connecting by connecting the connecting tube (2), the body (1) The other end of the block is pierced by a press and then burring, and is configured to weld and join two vent tubes.

또한, 본 고안에서는 상기 벤트튜브(3),(4)를 철제 파이프(3s),(4s)와 동제 파이프(3c),(4c)로 구성하되, 철제 파이프(3s),(4s)를 몸체(1)에 강제 압입시키고, 동제 파이프(3c),(4c)와의 결합부와 버링부(1d)를 용접, 일체화하고 있다.In addition, in the present invention, the vent tubes 3 and 4 are composed of steel pipes 3s and 4s and copper pipes 3c and 4c, but the steel pipes 3s and 4s are body. It is press-fitted to (1), and the joining part and burring part 1d with copper pipe 3c, 4c are welded and integrated.

즉, 상기한 몸체(1)는 가능한 용접부분이 최소화 되도록 1피스 구조로 하되, 기존의 동제 파이프의 일부를 철제 파이프로 바꾸어 경제성을 갖도록 한 것이다.That is, the body 1 is one-piece structure so as to minimize the possible welded portion, it is to replace the existing copper pipe part of the steel pipe to have an economical efficiency.

한편, 상기 몸체(1)의 내부에는 스크린(5)과 스크린홀더(6)로 이루어진 배플(7)이 장착되는데, 이는, 벤트튜브(3),(4)를 통해 몸체(1)의 내부로 유입되는 냉매가스가 전방의 커넥팅튜브(2)를 통해 배출될 때, 냉매가스 중에 기화하지 못한 냉매액이나 이물질 등이 상기 스크린(5)을 통하여 걸러지면서 기체화 되도록 유도하는 역할을 하게 된다.On the other hand, the inside of the body (1) is equipped with a baffle (7) consisting of a screen (5) and the screen holder (6), which is through the vent tube (3), (4) into the interior of the body (1) When the incoming refrigerant gas is discharged through the front connecting tube 2, the refrigerant liquid or foreign matter which cannot be vaporized in the refrigerant gas is filtered through the screen 5 to induce gasification.

상기한 본 고안의 어큐무레이터의 제조공정을 참고로 살펴보면, 먼저 몸체(1)에 적합한 길이로 철판을 딥 드로잉하여 만들어진 관(파이프)의 내부에, 별도 준비한 배플(7)을 끼운 다음, 커넥팅튜브(2)측은 CNC 선반에 설치된 로울러를 이용하여 직경이 좁아지게 스피닝 가공하게 되는데, 이 때, 축관부(1a)의 내경은 커넥팅튜브(2)와 빡빡한 맞춤으로 끼워질 정도로 가공한다.Referring to the manufacturing process of the accumulator of the present invention described above, first, the baffle (7) prepared separately in the tube (pipe) made by deep drawing the iron plate to a length suitable for the body (1), then connecting The side of the tube 2 is spun to have a narrower diameter by using a roller installed on a CNC lathe. At this time, the inner diameter of the shaft tube part 1a is processed to fit tightly with the connecting tube 2.

딥 드로잉하여 막혀 있는 반대쪽은 프레스로 피어싱한 다음, 버링 가공하여 2개의 벤트튜브(3),(4)를 끼워 넣고, 약 1,000 ~ 1,100℃를 유지하는 로(爐)의 내부를 통과시키면서, 용접재료가 용융되도록 하여 완성된 제품을 얻게 되는 것이다.The other side that is blocked by deep drawing is pierced by a press, and then burring, inserts two vent tubes (3) and (4), and passes through the inside of the furnace maintaining about 1,000 to 1,100 ° C. The material is melted to obtain a finished product.

여기서, 상기 벤트튜브(3),(4)는 철제 파이프(3s),(4s)와 동제 파이프(3c),(4c)로 구성하는데, 철제 파이프(3s),(4s)의 일단을 확관(擴管)하여 철제 파이프(3s),(4s) 부분을 몸체(1)에 강제 압입시키고, 철제 파이프(3s),(4s) 내부에 동제 파이프(3c),(4c)를 끼운 다음 버링부(1d)를 용접하여 완성하는 것이다.Here, the vent tubes 3 and 4 are composed of steel pipes 3s and 4s and copper pipes 3c and 4c, and one end of the steel pipes 3s and 4s is expanded. The steel pipes (3s) and (4s) to be forced into the body (1), and the copper pipes (3c) and (4c) are inserted into the steel pipes (3s) and (4s), and then the burring part ( 1d) is completed by welding.

여기서, 상기 철제 파이프(3s),(4s)와 동제 파이프(3c),(4c)의 용접, 그리고 철제 파이프(3s),(4s) 상부와 버링부(1d)의 용접은 서로 용접재료를 놓는 위치를 달리하여, 예컨대 전자는 아래쪽으로, 후자는 위쪽으로 용접하여 서로 간섭 없이 용접이 용이하도록 하는 것이 바람직하다.Here, the welding of the steel pipes 3s, 4s and the copper pipes 3c, 4c, and the welding of the upper parts of the steel pipes 3s, 4s and the burring portion 1d place welding materials together. By varying the position, for example, the former is welded downward and the latter is welded upward to facilitate welding without interference with each other.

또한, 용접 시 각 재질의 특성을 고려하는 것이 좋은데, 몸체(1)는 강철인 반면, 양측 축관단부(1c)와 버링부(1d)내에 끼워진 커넥팅튜브(2)는 동제 파이프이고, 벤트튜브(3),(4)는 철제 파이프(3s),(4s) 혹은 동제 파이프(3c),(4c)로서 서로 용융점이 다르므로 로의 내부에서 용접을 수행하여야만 한다.In addition, it is good to consider the characteristics of each material during welding, while the body 1 is steel, while the connecting tube 2 fitted in both shaft end portions 1c and the burring portion 1d is a copper pipe, and a vent tube ( 3) and (4) are steel pipes (3s), (4s) or copper pipes (3c) and (4c), which have different melting points. Therefore, welding must be performed in the furnace.

이와 같이 구성된 본 고안의 어큐무레이터는, 스피닝과 프레스 공법에 의해 냉간 가공되므로, 두께가 균일하며 몸체의 이음매가 없어서, 종래와 같이 용접이음에 의한 누설의 염려가 없어 냉매가스의 누설위험을 최소화시킬 수 있을 뿐만 아니라, 몸체를 가격이 저렴한 강철판을 이용하고, 또한 내부의 벤트튜브의 일부를 강철 파이프로 구성함으로써, 원가절감을 꾀할 수 있는 것은 물론, 철제 파이프를 몸체 내에 강제 압입 시킴으로써, 종래 삽입 부분이 몸체의 축관부에 끼워 용접할 때 미세하게 움직여 삐뚤어 질 수 있는 단점을 개선할 수 있는 것이다.Since the accumulator of the present invention configured as described above is cold worked by the spinning and pressing method, the thickness is uniform and there is no seam of the body, thus minimizing the risk of leakage of refrigerant gas because there is no fear of leakage due to welding joints as in the prior art. Not only can it be made, but the body is made of low-cost steel plate, and part of the internal vent tube is made of steel pipe, so that cost can be reduced, and the steel pipe is forcibly pressed into the body. The part is inserted into the shaft portion of the body to improve the disadvantage that the movement can be twisted fine when welding.

이상 설명한 바와 같이, 본 고안에 따르면, 기존의 2피스로 되어 있던 몸체를 용접부위 없이 1피스로 만들어, 냉동설비에서 가장 핵심인 누설의 위험을 획기적으로 개선함과 동시에, 기존에 고가의 동제 파이프를 사용하던 벤트튜브의 일부를 가격이 저렴한 강철 파이프로 구성함으로써 제조원가를 낮출 수 있는 효과가 있어 관련 분야에의 이용 및 응용이 기대된다 하겠다.As described above, according to the present invention, the conventional two-piece body is made of one piece without welding, thereby dramatically improving the risk of leakage, which is the most important factor in the refrigerating facility, and at the same time, expensive copper pipes. Part of the vent tube that was used as a low-cost steel pipe has the effect of lowering the manufacturing cost is expected to be used and applied in related fields.
