본 고안은 보일러용 점화장치에 관한 것으로서, 특히 점화장치의 점화봉과 열감지봉 외부에 구비된 애자의 외부에 내열설 합성수지재를 이용하여 일체로 인서트 몰딩한 보일러용 점화장치에 관한 것이다.The present invention relates to an ignition device for a boiler, and more particularly, to an ignition device for an integrally molded insert using a heat-resistant synthetic resin material on the outside of an insulator provided on an ignition rod and a heat sensing rod.
일반적으로 보일러의 점화장치는 연소장치에 구비되어 전자적인 전극을 발생시키므로서 연료가스 및 기름을 착화시킬 수 있도록 하고, 또한 열감지봉이 연소열을 감지할 수 있게한 것으로서, 종래에는 점화장치의 점화봉과 열감지봉 외부의 적정위치로 점화봉과 열감지봉을 보호하기 위해 애자를 성형 구비함에 따라 고열에 의하여 애자에 클랙이 발생하여 파손되고, 열감지봉의 경우 연소시에 발생한 고열과 외부의 차가운 공기와 접촉되어 발생하는 결로현상에 의해 습기가 열감지봉에 접촉되므로서 연소장치에서 발화되는 열의 감지를 정확히 할 수 없는 문제점이 있었다. 따라서, 본 고안은 상기와 같은 종래의 문제점을 해결하기 위하여 안출한 것으로서, 점화장치의 점화봉과 열감지봉 외부에 구비된 애자의 외부에 내열성 합성수지재를 이용하여 일체로 인서트 몰딩하므로서 고열에 의한 점화장치의 애자를 보호하고, 습기가 열감지봉에 침투하는 것을 방지한 것을 목적으로 한다.In general, the ignition device of a boiler is provided in the combustion device so as to ignite fuel gas and oil by generating an electronic electrode, and the heat sensing rod can sense the heat of combustion. As the insulator is formed to protect the ignition rod and the heat sensing rod to an appropriate position outside the heat sensing rod, cracks are generated in the insulator due to high heat, and the heat sensing rod is in contact with the high temperature generated during combustion and external cold air. Due to the dew condensation that occurs, the moisture is in contact with the heat sensing rod, there is a problem that can not accurately detect the heat ignited in the combustion device. Therefore, the present invention has been made to solve the above-mentioned problems, the ignition device by high heat by insert molding integrally using a heat-resistant synthetic resin material on the outside of the ignition rod and the heat sensing rod of the ignition device The purpose is to protect the insulators and prevent moisture from penetrating the thermal sensing rods.
이하, 첨부된 도면에 의하여 본 고안의 구성을 상세하게 설명하면 다음과 같다.Hereinafter, the configuration of the present invention in detail by the accompanying drawings as follows.
점화봉(2)과 열감지봉(3)이 구비된 점화장치(1)에 있어서, 상기 점화봉(2)과 열감지봉(3) 외부에 성형되는 애자(4)의 외부에 내열성 합성수지재로된 보호구(5)와 베이스(6)를 일체로 인서트 사출 성형한 것이다.An ignition device (1) having an ignition rod (2) and a heat sensing rod (3), wherein the ignition rod (2) and the heat sensing rod (3) are formed of a heat-resistant synthetic resin on the outside of the insulator (4) The insert 5 is integrally inserted into the protective tool 5 and the base 6.
상기 열감지봉(3)의 외부에 성형된 애자(4)는 길이(L)을 열감지봉(3)에 최대한 둘러싸일수 있도록 형성하고, 점화봉(2)의 선단에 구비된 전극발생부(7)는 평편하게 형성한 것이다.The insulator 4 formed on the outside of the heat sensing rod 3 is formed to have a length L so as to be surrounded by the heat sensing rod 3 as much as possible, and the electrode generator 7 provided at the tip of the ignition rod 2. Is formed flat.
이와같이 구성된 본 고안의 작용효과를 상세하게 설명하면 다음과 같다.Referring to the effect of the present invention configured in this way in detail as follows.
보일러의 연소장치에 설치되는 점화장치(1)의 점화봉(2)과 열감지봉(3)외부에 성형되는 애자(4)의 외부로 내열성 합성수지재의 보호구(5)와 베이스(6)를 일체로 인서트 사출 성형함에 따라 보일러의 가동시 연소장치에서 발생한 고열에 의한 애자(4)의 변형(클랙이나 파손)을 내열성 합성수지재의 보호구(5)와 베이스(6)가 방지할 수 있는 것이다. 즉, 애자(4)의 외부에 성형된 내열성 합성수지재의 보호구(5)와 베이스(6)에 의해 애자(4)에 전달되는 고열을 최소화하여 변형을 방지할 수 있도록 한 것이다.The protective device 5 and the base 6 of the heat-resistant synthetic resin material are integral to the outside of the ignition rod 2 and the insulator 4 formed outside the heat sensing rod 3 of the ignition device 1 installed in the combustion device of the boiler. By insert injection molding, the protector 5 and the base 6 of the heat-resistant synthetic resin material can prevent the deformation (cracking or damage) of the insulator 4 due to the high heat generated in the combustion device when the boiler is operated. That is, the high temperature transmitted to the insulator 4 by the protective device 5 and the base 6 of the heat-resistant synthetic resin material molded on the outside of the insulator 4 is minimized to prevent deformation.
또한, 상기 열감지봉(3) 외부에 성형된 애자(4)는 이 외부에 성형되는 내열성 합성수지재의 보호구(5)에 의해 고열에 의한 변형이 방지되므로서 열감지봉(3) 외부로 최대한 많은 부분을 둘러싸일 수 있게 애자(4)의 전체길이(L)를 최대한 길게 한다.In addition, the insulator 4 formed on the outside of the heat sensing rod 3 is prevented from deformation due to high heat by the protective tool 5 of the heat-resistant synthetic resin material formed on the outside, so that a large portion of the insulator 4 is formed outside the heat sensing rod 3. The total length L of the insulator 4 is made as long as possible so that it may be enclosed.
따라서, 연소장치에서 연소시에 발생한 고열과 대기증의 차가운 공기가 접합되어 발생하는 결로현상에 의한 습기가 열감지봉(3)과 애자(4)의 접촉부(P)사이로 유입될때 열감지봉(3) 전체로 침투되는 것을 방지하여 연소장치의 연소열을 정확히 감지할 수 있도록 하였다. 또한, 상기 점화봉(2)의 선단에 구비된 전극발생부(7)는 평편부로 형성하여 서로 대향되는 전극발생부(7)에서의 전극발생 효율을 높였다.Therefore, when the moisture from the condensation phenomenon caused by the high heat generated during combustion in the combustion apparatus and the cold air of the atmosphere is introduced into the contact portion P between the heat sensing rod 3 and the insulator 4, the heat sensing rod 3 It prevents the penetration into the whole so that the heat of combustion of the combustion device can be detected accurately. In addition, the electrode generator 7 provided at the tip of the ignition rod 2 is formed as a flat portion to increase the electrode generation efficiency in the electrode generator 7 facing each other.
상기 전극발생부(7)에서 발생되는 전극의 효율을 높일 수 있도록 한 것은 평편하게 형성된 전극발생부의 단면 체적면적을 높임으로 가능하도록 한 것이다.In order to increase the efficiency of the electrode generated in the electrode generator 7 is to increase the cross-sectional area of the electrode generator is formed flat.
이상에서와 같이 본 고안의 점화장치의 점화봉과 열감지봉 외부에 구비된 애자의 외부에 내열설 합성수지재를 이용하여 일체로 인서트 몰딩한 것을 방지하여 열감지기능을 향상시키며, 점화봉의 전극발생부를 평편하게 하여 전극발생 효율을 높일 수 있는 효과가 있는 것이다.As described above, the thermal sensing function is improved by preventing the insert molding integrally by using a heat-resistant synthetic resin material on the outside of the ignition rod and the heat sensing rod of the ignition device of the present invention. It is easy to increase the electrode generation efficiency.
