본 발명은 공기조화기에 관한 것으로, 더욱 상세하게는 실외기로부터 토출되는 냉매를 2이상의 실내기로 분배하기 위하여 냉매관에 연결되는 냉매 분기관 및 이를 구비한 공기조화기에 관한 것이다.The present invention relates to an air conditioner, and more particularly, to a refrigerant branch pipe connected to a refrigerant pipe for distributing refrigerant discharged from an outdoor unit to two or more indoor units, and an air conditioner having the same.

일반적으로, 공기조화기는 냉동싸이클을 이용하여 실내공기의 온도 및 습도를 조절하는 장치로, 하나의 본체로 이루어진 일체형과, 실내기와 실외기로 이루어진 분리형으로 구분된다.In general, an air conditioner is a device for controlling the temperature and humidity of indoor air using a refrigeration cycle, and is classified into an integrated type consisting of one body and a separate type consisting of an indoor unit and an outdoor unit.

분리형의 경우, 한대의 실외기에는 하나의 실내기가 설치되는 것이 일반적이나, 최근에는 하나 이상의 실외기에 복수의 실내기가 연결되어 설치되는 멀티형 제품도 생산되고 있다.In the case of the separate type, one indoor unit is generally installed in one outdoor unit, but recently, a multi-type product in which a plurality of indoor units are connected and installed in one or more outdoor units is also produced.

멀티형 공기조화기의 경우, 실외기로부터 토출되는 냉매를 각 실내기로 분배하기 위하여 실외기와 실내기 사이에 연결되는 냉매관에 Y자형의 분기관이 연결되기도 한다.In the case of a multi-type air conditioner, a Y-shaped branch pipe may be connected to a refrigerant pipe connected between the outdoor unit and the indoor unit to distribute the refrigerant discharged from the outdoor unit to each indoor unit.

대한민국 특허공개공보 1995-10995호에는 냉매 분기관 구조에 개시되어 있는데, 이러한 종래의 냉매 분기관은 직경이 큰 관을 압착하여 두 개의 분기부를 형성하고, 두 개의 분기부사이의 압착부분을 용접하는 방법으로 제작하게 된다.Korean Patent Laid-Open Publication No. 1995-10995 discloses a refrigerant branch pipe structure. The conventional refrigerant branch pipe is formed by pressing a tube having a large diameter to form two branch portions, and welding the compressed portion between the two branch portions. How to make it.

그러나, 이러한 종래의 냉매 분기관은 분기부 사이의 압착부분을 압착하고 용접하는 과정에서 용접물이 표면에만 융착되고 압착부분의 내부에까지는 융해된 용접물이 도달하지 못하게 된다.However, in the conventional refrigerant branch pipe, the welded material is welded only to the surface and the melted welded material does not reach the inside of the compressed part in the process of pressing and welding the compressed parts between the branched parts.

따라서, 냉매 분기관에서 분기분사이의 압착부분이 상대적으로 강성이 취약 하여 냉매 분기관이 냉매관에 설치되고 내부에 고압의 냉매가 충진되어 공기조화기가 가동될 경우 압착부분으로부터 크랙이 발생되면서 냉매 분기관이 파손되는 문제점이 있었다.Therefore, the crimping portion between the branching branches in the refrigerant branching pipe is relatively stiff, so when the refrigerant branching pipe is installed in the refrigerant pipe, the high pressure refrigerant is filled inside, and the air conditioner is operated, cracks are generated from the crimping section. There was a problem that the branch pipe is broken.

아울러, 이러한 취약점을 보완하기 위해 황동과 같은 구리합금을 냉매관 및 용접물의 재질로 사용할 경우 그에 따라 제품의 원가가 상승되는 문제점이 있었다. In addition, when using a copper alloy such as brass as a material of the refrigerant pipe and the welded material to compensate for this weakness, there was a problem in that the cost of the product increases.

본 발명의 이와 같은 문제점을 해결하기 위한 것으로, 본 발명의 목적은 냉매라인에 이상 고압이 작용되거나 장시간 사용에 따른 피로에 의해 파손되지 않도록 충분한 내압 강도를 갖는 냉매 분기관 및 이를 구비한 공기조화기를 제공하는 것이다.In order to solve the problems of the present invention, an object of the present invention is to provide a refrigerant branch pipe and an air conditioner having a sufficient pressure resistance strength so that the abnormal high pressure is not applied to the refrigerant line or damaged by fatigue due to long time use.

이하에는 본 발명의 바람직한 실시예를 첨부한 도면을 참조로 하여 상세히 살펴본다.Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail.

본 발명에 따른 공기조화기는 실내에 설치되는 실내기(2,3)와 외부에 설치되는 실외기(1)를 포함한다.The air conditioner according to the present invention includes indoor units 2 and 3 installed indoors and outdoor units 1 installed outside.

실외기(1)에는 냉동싸이클의 순환을 위해 계속적으로 냉매를 가압하는 압축기(미도시)와, 냉매와 실외공기와의 열교환을 위한 열교환기(미도시)가 마련되며, 본체(1) 외면에는 상기 열교환기로의 공기순환을 위한 흡입구(1a) 및 토출구(1b)가 마련되어 있다.The outdoor unit 1 is provided with a compressor (not shown) for continuously pressurizing the refrigerant for circulation of the refrigeration cycle, and a heat exchanger (not shown) for heat exchange between the refrigerant and outdoor air. Inlet port 1a and outlet port 1b are provided for air circulation to the heat exchanger.

이러한 실외기(1)에 대응되어 실내에는 실내기(2)(3)가 설치되며, 실내 기(2)(3) 내에도 실내공기와의 열교환을 위한 열교환기(미도시)가 설치된다.Indoor units 2 and 3 are installed indoors corresponding to the outdoor unit 1, and heat exchangers (not shown) are installed in the indoor units 2 and 3 to exchange heat with the indoor air.

실내기(2,3)와 실외기(1) 사이에는 냉매가 순환되는 냉매유로(4)가 마련되는데, 본 발명에 따른 공기조화기와 같이 2이상의 실내기를 구비하여 복수의 공간을 개별 냉난방하는 멀티형 공기조화기의 경우 냉매유로(4)에 냉매가 분기되는 분기점(5)이 존재하게 된다.A refrigerant flow path 4 through which refrigerant is circulated is provided between the indoor units 2 and 3 and the outdoor unit 1. A multi-type air conditioner having two or more indoor units such as an air conditioner according to the present invention for individually cooling and heating a plurality of spaces is provided. In the case of the air, the branch point 5 at which the refrigerant branches in the refrigerant passage 4 is present.

도 2 및 도 3은 이러한 분기점(5)에 설치되는 냉매 분기관(10)을 도시한 것으로, 냉매분기관(10)은 내부에 냉매의 분기를 위한 분기유로가 형성된 연결부재(11)와, 이 연결부재(11)에 접속되는 주 냉매관(20), 제1분기관(30) 및 제2분기관(40)을 포함한다.2 and 3 illustrate a refrigerant branch pipe 10 installed at the branch point 5, the refrigerant branch pipe 10 includes a connection member 11 having a branch flow path for branching the refrigerant therein; The main refrigerant pipe 20, the 1st branch pipe | tube 30, and the 2nd branch pipe | tube 40 connected to this connection member 11 are included.

연결부재(11)는 내부에 대략 Y자형 분기된 3방향 유로가 형성되어 이중 하나의 유로는 분기되기 전 주관부(12)를 형성하고, 나머지 두 유로는 주 관부(12)로부터 분기되어 연통되는 제1분기부(13) 및 제2분기부(14)를 형성하게 된다.The connecting member 11 is formed with a three-way flow path that is approximately Y-shaped branched therein, one of which flows to form a main pipe portion 12 before branching, and the other two flow paths are branched from the main pipe portion 12 to communicate with each other. The first branch portion 13 and the second branch portion 14 are formed.

이러한 연결부재(11)의 구조는 소정길이의 관을 가압하여 소성가공에 의해 얻게 되는데, 이때 주 관부(12)는 내경이 작아지도록 축관하고, 주 관부(12)의 반대측은 확관한 상태에서 서로 대향되는 양단을 가압, 압착시켜 제1분기부(13) 및 제2분기부(14)를 형성하게 된다.The structure of the connecting member 11 is obtained by the plastic working by pressing the pipe of a predetermined length, wherein the main pipe portion 12 is the tube so that the inner diameter is smaller, the opposite side of the main pipe portion 12 in the expanded state Both opposite ends are pressed and compressed to form the first branch portion 13 and the second branch portion 14.

따라서, 제1분기부(13) 및 제2분기부(14)사이에는 소정길이 만큼 압착되어 형성된 연결부(15)가 마련되어 두 유로를 구획하게 된다.Therefore, a connection part 15 formed by being pressed by a predetermined length is provided between the first branch part 13 and the second branch part 14 to divide the two flow paths.

연결부(15)의 선단에는 연결부(15)의 길이방향으로 함몰된 형상으로 마련되는 요홈인 틈새부(16)가 마련되는데, 이는 압착형성된 연결부(15)가 냉매에 의해 가해지는 내압에 대하여 충분한 강성을 갖도록 용접할 때 용융된 용접물이 틈새부(16) 내부로 함입되어 연결부(15)의 선단 표면 뿐만 아니라 내부에까지 용접물이 도달하여 용접이 이루어지게 하기 위함이다.At the distal end of the connecting portion 15, there is provided a gap portion 16, which is a recess provided in a shape recessed in the longitudinal direction of the connecting portion 15, which is sufficient rigidity against the internal pressure exerted by the refrigerant by the connecting portion 15 formed by the refrigerant. When welding to have a molten weld is to be embedded in the gap 16, the weld reaches to the interior as well as the front end surface of the connecting portion 15 to make the welding.

연결부(15)를 형성하기 위한 압착과정에서 연결부(15) 양측에는 제1분기부(13) 및 제2분기부(14)에 삽입되는 제1분기관(30) 및 제2분기관(40)의 외면과 약간의 틈이 생기게 되고 이 틈으로 용융물이 침투될 수 있으나, 이외의 부분에는 용접물이 침투할 공간이 없게 되어 틈새부(16)가 없을 경우 연결부(15)의 선단 표면에만 용접이 이루어지게 된다.The first branch pipe 30 and the second branch pipe 40 which are inserted into the first branch 13 and the second branch 14 on both sides of the connecting portion 15 in the crimping process for forming the connecting portion 15. There is a slight gap with the outer surface of the melt may penetrate into the gap, but other parts there is no space for the weld to penetrate, if there is no gap 16, the welding is made only on the front end surface of the connecting portion 15 You lose.

따라서, 틈새부(16)는 연결부(16) 선단 중앙을 중심으로 소정의 폭과 깊이로 형성되는 것이 바람직하며, 도 4에는 이러한 틈새부(16)가 형성된 예를 도시한 것이다.Therefore, the gap 16 is preferably formed with a predetermined width and depth around the center of the tip of the connecting portion 16, and FIG. 4 shows an example in which the gap 16 is formed.

상기 틈새부(16)는 압착하여 연결부(15)를 형성하는 과정에서 압착되어 연결부(15)를 형성하는 양단의 소정위치에 틈새부(16)를 형성할 공간만큼 돌출형성된 핀형태의 금형을 삽입한 상태에서 프레싱하여 얻을 수 있다.The gap portion 16 is pressed in the process of forming the connection portion 15 by pressing to insert a mold in the form of a pin protruding as a space to form the gap portion 16 at predetermined positions of both ends forming the connection portion 15. It can be obtained by pressing in a state.

이러한 틈새부(16)가 형성된 상태에서 연결부(15)를 용접하게 되면, 틈새부(16)를 따라 용접물이 모세관 현상에 의해 내부로 침투하여 연결부(15) 내부의 공간을 용접하여 접합시키되며, 아울러 상술한 바와 같이 연결부(15)의 양측의 제1분기관(30) 및 제2분기관(40)과 인접하는 부분에 존재하게 되는 틈을 따라 용접물이 침투할 수 있다.When the connecting portion 15 is welded in the state where the gap portion 16 is formed, the weld material penetrates into the inside by the capillary phenomenon along the gap portion 16 to weld the space inside the connecting portion 15 to be joined. In addition, as described above, the weldment may penetrate along a gap existing in a portion adjacent to the first branch pipe 30 and the second branch pipe 40 on both sides of the connection part 15.

그러나, 이러한 용접과정에서 용접물이 연결부(15)의 틈을 따라 연결부 재(11) 내부의 유로로 용접물이 유입될 경우 이러한 냉매 분기관(10)이 냉매유로에 설치된 상태에서 냉매에 부유하는 찌꺼기를 생성하게 되고, 이는 공기조화기 전체의 신뢰성을 저하시키게 된다.However, in the welding process, when the weld material flows into the flow path inside the connection member 11 along the gap of the connection part 15, the residues floating in the refrigerant in the state where the refrigerant branch pipe 10 is installed in the refrigerant flow path are prevented. This, in turn, lowers the reliability of the entire air conditioner.

따라서, 연결부(15)를 용접하는 과정에서 내부유로로 용접물이 흘러가지 않도록 제1분기부(13) 및 제2분기부(14)의 내부에는 내주연을 따라 중심방향으로 돌출된 단차(17)가 마련된다. Therefore, the step 17 protruding toward the center along the inner circumference of the first branch 13 and the second branch 14 so that the weld material does not flow into the internal flow path during the welding of the connecting portion 15. Is prepared.

상기 단차(17)는 틈새부(16) 유입되는 용접물과 제1분기부(13) 및 제2분기부(14)의 내경부와 이에 삽입되는 분기관(30,40)사이의 틈으로 유입되는 용접물이 내부유로로 흘러 들어가지 않도록 차단함과 동시에 분기관(30,40)을 삽입하는 단계에서 적정한 삽입깊이를 안내하는 역할을 하게 된다.The step 17 is introduced into the gap between the welding material flowing into the gap portion 16 and the inner diameter portion of the first branch portion 13 and the second branch portion 14 and the branch pipes 30 and 40 inserted therein. It prevents the weld from flowing into the internal flow path and serves to guide the proper insertion depth in the step of inserting the branch pipes 30 and 40.

이러한 냉매 분기관(10)은 실외기(1)로부터 토출되어 각각의 실내기(2,3)로 유입되는 냉매유로(4)에도 설치될 뿐만 아니라, 실내기(2,3)에서 실외기(1)로 흐르는 냉매유로상에도 설치된다.The refrigerant branch pipe 10 is installed in the refrigerant passage 4 discharged from the outdoor unit 1 and introduced into the respective indoor units 2 and 3, and also flows from the indoor units 2 and 3 to the outdoor unit 1. It is also installed on the refrigerant path.

또한, 본 실시예는 실내기와 실내기 사이의 냉매유로에 냉매 분기관이 설치된 예를 기준으로 설명하였으나, 냉매 분기관은 실외기 내에도 내장될 수 있음은 물론이다.In addition, although the present embodiment has been described with reference to an example in which a refrigerant branch pipe is installed in the refrigerant passage between the indoor unit and the indoor unit, the refrigerant branch pipe may be embedded in the outdoor unit.

상술한 바와 같이 본 발명에 따른 공기조화기는 두 분기관 사이의 연결부 내부를 융착시키기 위한 용접물이 함입되는 공간인 틈새부가 마련된 냉매 분기관을 구비한다.As described above, the air conditioner according to the present invention includes a refrigerant branch pipe having a gap portion, which is a space in which a weldment for fusion welding the interior of the connection portion between the two branch pipes is inserted.

따라서, 연결부의 내압강도가 향상되어 피로에 의한 파손을 방지하기 위한 충분한 안전율을 확보할 수 있게 된다.Therefore, the pressure resistance of the connecting portion is improved, thereby ensuring a sufficient safety factor for preventing breakage due to fatigue.

또한, 용접하는 과정에서 연결부재의 내부 유로로 용접물이 유입되는 것을 차단하기 위한 단차가 마련되어 냉매배관 전체의 신뢰성이 향상되는 효과가 있다.In addition, a step is provided to block the inflow of the weld material into the inner flow path of the connecting member in the welding process has the effect of improving the reliability of the entire refrigerant pipe.
