본 발명은 전열선 내장형 온수관의 밀폐구조에 관한 것으로서, 더욱 상세하게는 전열선이 내장된 온수관의 단부를 긴밀하게 밀폐하여 온수관 내부의 난방수가 누설되지 않도록 수밀성을 향상함과, 동시에 전열선의 발열로 인한 고무마개의 손상을 최소화하여 수명을 연장할 수 있는 전열선 내장형 온수관의 밀폐구조에 관한 것이다.The present invention relates to a sealed structure of a heating wire built-in hot water pipe, and more particularly, to tightly seal an end portion of a hot water pipe having a heating wire, thereby improving watertightness so that the heating water inside the hot water pipe does not leak, and at the same time, heat generation of the heating wire. It relates to a sealed structure of a heating wire built-in hot water pipe that can extend the life by minimizing the damage of the rubber stopper.

일반적으로 전열선이 내장된 난방용 온수관의 경우, 온수관의 내부에 담겨있는 난방수가 전기적인 에너지에 의해 발열하는 전열선으로 가열하여 소정의 온도로 발열이 이루어진다. In general, in the case of a heating hot water pipe in which a heating wire is embedded, the heating water contained in the inside of the hot water pipe is heated by a heating wire that generates heat by electric energy, thereby generating heat at a predetermined temperature.

이러한 전열선 내장형 온수관을 밀폐하기 위한 종래의 기술로는 실용신안출원 제:1999-19789호의 명칭: '전열선이 삽입된 온수관의 단부의 밀폐장치'가 있으며, 간략하게는 플럭의 내부에 삽입되고 전열선이 관통하는 실리콘 마개를 플럭의 중앙 요입부의 턱에 닿게 삽입하고 크라운 너트가 체결되면서 온수관의 단부가 밀 폐되도록 한 구성이다.The conventional technique for sealing such a heating wire built-in hot water pipe is Utility Model Application No .: 1999-19789 name: 'sealing device of the end of the hot water pipe is inserted into the heating wire,' and is briefly inserted into the floc Insert the silicone stopper penetrating the heating wire to the chin of the central recess of the floc and the end of the hot water pipe is closed as the crown nut is fastened.

그러나, 상기의 종래기술은 상기 실리콘 마개가 통공 속으로 밀려 들어가면서 밀폐부위가 헐거워지는 단점과, 전열선의 발열로 인해 열적 변형 및 손상이 발생하여 누수현상이 발생하고 수명이 급격히 단축되며, 또는 온수관의 밀폐부위에서 전열선이 구부려지거나 접촉으로 인한 손상과, 전열선의 수명이 급격히 단축되는 문제점이 발생하였다.However, the prior art has the disadvantage that the sealing portion is loosened as the silicone stopper is pushed into the through hole, and thermal deformation and damage occurs due to the heating of the heating wire, which causes leakage and shortens the lifespan. There was a problem that the heating wire is bent or contact damage in the sealed portion of the and the life of the heating wire is shortened dramatically.

이로인해, 본 발명의 출원인에 의해 특허출원 제: 2007-34922호와 2007-48992호의 동일명칭: '전열선 내장형 온수관의 밀폐구조' 및, 실용신안출원 제: 2007-5850호의 명칭: '온수관 전열선의 결합구조' 외 다수의 건으로 이미 제안된 바에 있으며, 이는 온수관 및 전열선의 결합 및 밀폐구조에 관한 것으로서 세부적인 상세한 설명을 생략하기로 한다. For this reason, according to the applicant of the present invention, the patent names: 2007-34922 and 2007-48992, the same name: 'sealing structure of the hot water tube built-in heating wire', and Utility Model Application No. 2007-5850, name: 'hot water pipe Coupling structure of heating wire 'has been proposed as a number of other cases, which are related to the coupling and sealing structure of the hot water pipe and heating wire will be omitted in detail.

먼저, 상기 피팅(10)의 중앙에는 양측으로 개통된 통공(12)이 형성되며, 일측으로 제1 돌출부(12)가 형성되고, 타측으로 제2 돌출부(16) 및 제3 돌출부(17)가 단을 이루면서 온수관이 삽입되도록 홈이 형성되어 있다. 상기 제1, 제2 돌출부(14,16)는 외주에 수나사를 형성하여 캡너트(20)와 온수관을 연결하기 위한 배관너트(50)가 각각 조립된다.First, a through hole 12 is opened at both sides in the center of the fitting 10, and a first protrusion 12 is formed at one side, and a second protrusion 16 and a third protrusion 17 are formed at the other side. The groove is formed to form a stage so that the hot water pipe is inserted. The first and second protrusions 14 and 16 form male threads on the outer circumference thereof, and pipe nuts 50 for connecting the cap nut 20 and the hot water pipe are assembled.

상기 고무마개(30)는 외측으로 갈수록 직경이 확장되고 외측에 단테(32)를 형성하여 제1 돌출부의 외측 선단면에 걸쳐지도록 하여 수밀(水密)성을 향상시키며, 안쪽으로 오목한 요홈(36)을 형성하여 전선의 접속부(3)를 안전하게 수용하여 보호한다. 또한, 타측의 결속부(40)는 도면에서처럼, 충분히 연장하여 피팅의 제3 돌출부(17) 외측으로 돌출시켜 노출되도록 구성한다. 상기 접속부(3)는 피팅의 일측에서 전원선(1)이 상기 캡너트의 구멍(22)을 관통하고 타측의 전열선(2)이 고무마개의 전열선구멍(37)을 통과하여 서로 연결된다.
