Abstract

본 발명은 배관 연결부의 구조를 개선하여 조립의 간편화와 작업시간의 단축, 냉매누설의 원인을 근본적으로 방지하고자 발명한 분리형 에어콘의 배관연결장치에 관한 것으로, 증발기(11)가 내장되어 있는 실내기(10)와, 응축기(21), 압축기(22) 및 모세관(23) 등이 내장되어 있는 실외기(20)와, 실내기(10)와 실외기(20)를 연결하는 연결배관(30)으로 구성한 분리형 에어콘의 배관연결구조에 있어서, 일측배관(30a)에 일체로 용접되는 소켓트플레어(40)와, 소켓트플레어(40)의 내주면에 유동되지 않도록 삽입설치되어 냉매의 누설을 차단하는 오링(50)과, 소켓트플레어(40)에 나사조립되어 연결배관(30)을 고정시켜 주는 플레어너트(60)과, 연결배관(30)의 외주면을 감싸서 조여 누설을 차단하는 동시에 플레어너트(60)의 조임력에 의하여 오링(50)에 밀착되는 스톱퍼(70)로 구성한다.The present invention relates to a pipe connecting device of a separate air conditioner invented to improve the structure of the pipe connecting portion to simplify the assembly and shorten the working time, and to prevent the leakage of refrigerant. The indoor unit having the evaporator 11 built-in ( 10) a separate air conditioner consisting of an outdoor unit 20 in which the condenser 21, the compressor 22, and the capillary tube 23 are embedded, and a connection pipe 30 connecting the indoor unit 10 and the outdoor unit 20 to each other. In the pipe connection structure, the socket flare 40 integrally welded to one side pipe (30a) and the O-ring 50 is inserted so as not to flow to the inner circumferential surface of the socket flare 40 to block the leakage of refrigerant And a flare nut 60 which is assembled to the socket flare 40 to fix the connection pipe 30 and wraps around the outer circumferential surface of the connection pipe 30 to block leakage and at the same time tighten the flare nut 60. By the stopper 70 in close contact with the O-ring 50 Configure.

Claims

In the pipe connection structure of a detachable air conditioner consisting of an indoor unit having an evaporator, an outdoor unit having a condenser, a compressor, and a capillary tube, and a connection pipe connecting the indoor unit and the outdoor unit, the socket flare is integrally welded to the compression pipe. O-rings that are inserted to prevent flow to the inner circumferential surface of the socket flare to block refrigerant leakage, flare nuts screwed to the socket flare to secure the connection pipe, and wrapped around the outer circumference of the connection pipe to block leakage. At the same time, the pipe connecting device of the separate air conditioner, characterized in that consisting of a stopper in close contact with the O-ring by the tightening force of the flare nut.

According to claim 1, The socket flare is formed on the inner peripheral surface to prevent the flow of the O-ring ring groove; The flare nut is to form a pressing projection on one side of the inner surface of the tube insertion hole to press the stopper with a tightening force; The stopper has a tube insertion hole formed so that the connecting pipe is inserted, and protrudes integrally with the inner surface of the pipe inserting hole side and extends in the circumferential direction when inserting the connecting pipe so as to forcibly wrap the outer peripheral surface to tighten and block the leakage. Separating air conditioner pipe connecting device, characterized in that formed by forming a compression ring piece slightly smaller than the outer diameter of the connection pipe.
