It relates to a sealed structure of a heating wire built-in hot water pipe that is waterproof to prevent leakage of the heating water in the hot water pipe by fastening a cap with a packing built into both sides of the fitting.

일반적으로 전열선이 내장된 난방용 온수관의 경우, 온수관의 내부에는 전열선이 내장되고 난방수로 충진되고 전원과 연결되는 전열선의 발열로서 난방수와 열교환되도록 하여 난방수를 소정의 온도로 가열시킨다. 이러한 온수관 및 전열선의 연결부를 밀폐하기 위한 종래의 기술로는 본 발명의 출원인에 의해 선 제안된 바 있는 특허출원 제: 2007-34922호와 2007-48992호의 동일명칭:‘전열선 내장형 온수관의 밀폐구조’ 및, 실용신안출원 제: 2007-5850호의 명칭:‘온수관 전열선의 결합구조’외 다수의 건이 있으며, 이는 온수관 및 전열선의 결합 및 밀폐구조에 관 한 것으로서 세부적인 상세한 설명을 생략하기로 한다. In general, in the case of a heating hot water pipe in which a heating wire is embedded, the heating water is heated inside the hot water pipe, filled with heating water, and heat-exchanged with the heating water as heat generated by the heating wire connected to the power source, thereby heating the heating water to a predetermined temperature. Conventional techniques for sealing the connection of the hot water pipe and the heating wire as patent applications that have been proposed by the applicant of the present invention: 2007-34922 and 2007-48992, the same name: 'sealing of the heating wire built-in hot water pipe And 'Utility Model Application No. 2007-5850': 'Combination structure of hot water pipe heating wire' and many other cases, which are related to the coupling and sealing structure of hot water pipe and heating wire, and the detailed description thereof will be omitted. Shall be.

그러나 종래의 기술은 전자의 경우, 피팅 내부에 접속부가 위치하고 방수부재에 의해 밀봉되도록 하는데, 전열선이 통과하는 부위에서 누수의 위험이 있었고, 전선의 결속작업이 불편하고 밀봉 시 접속부가 밀려 빠져나오는 등, 작업이 까다롭고, 차후 보수하기가 까다로운 단점이 있었다.However, in the former case, in the former case, the connection part is located inside the fitting and is sealed by the waterproof member. There is a risk of water leakage at the place where the heating wire passes, the binding work of the wire is inconvenient, and the connection part is pushed out when sealing. It was difficult to work with and difficult to repair later.

그리고 후자는, 방수부재를 충진하는 케이스 및 캡으로서 밀봉하기에는 다소 미흡한바, 아래와 같이 보완된 전열선 내장형 온수관의 밀폐구조를 제안한다.And the latter is somewhat insufficient to seal as a case and cap filling the waterproof member, proposes a sealed structure of the heating wire-embedded hot water pipes as described below.
