Description

시즈히터 {SHEATH HEATER} Sheath Heater {SHEATH HEATER}

본 고안은 2중의 절연구조를 형성한 시즈(Sheath)히터에 관한 것이다.The present invention relates to a sheath heater having a double insulation structure.

좀 더 구체적으로는 시즈히터를 구성함에 있어 그 피복층의 내부에 2중의 절연구조를 형성하여 절연저항을 극대화시키고, 절연내력을 크게 향상시킨 시즈히터를 제공하려는 것이다.More specifically, in forming the sheath heater, a double insulation structure is formed inside the coating layer to maximize the insulation resistance and to provide a sheath heater with a large improvement in the insulation resistance.

주지하다시피, 시즈히터는 금속보호관의 중심에 열선을 삽입시킨 후 상기 보호관과 열선의 사이에 마그네시아라고 하는 산화마그네슘의 절연분말을 충진하여 열선과 보호관 사이를 절연시킨 구조의 히터를 말하는 것으로 이러한 시즈히터는 진동과 충격에 강한 내구성을 가지고 있어 전기로, 건조기, 욕조, 반신욕조, 주조기, 오븐, 족온기 등 의 산업용 내지는 일반 민생용 가열제품의 가열히터로 널리 사용되는 제품이다.As is well known, sheath heater refers to a heater having a structure insulated between a heating wire and a protective tube by inserting a heating wire in the center of the metal protective tube and filling an insulating powder of magnesium oxide called magnesia between the protective tube and the heating wire. The heater has a strong durability against vibration and shock, and is widely used as a heating heater for industrial or general public heating products such as electric furnaces, dryers, bathtubs, half-baths, casting machines, ovens, and foot temperature heaters.

그러나 종래에 사용된 시즈히터는 그 구조가 니크롬이나 칸탈 등의 전열선을 피복용 튜브 내에 인입한 후 그 사이에 공간부에 마그네시아 분말을 충진하여 절연되게 한 후 상기 튜브의 표면에는 금속보호관을 끼운 구조로 되었다.However, the sheath heater used in the related art has a structure in which a heating tube such as nichrome or cantal is introduced into a coating tube and filled with magnesia powder in the space therebetween to insulate it, and then a metal protective tube is fitted on the surface of the tube. It became.

따라서 상기한 시즈히터를 욕조나 반신욕조, 족온기, 등과 같이 물을 가열하여 온수로 사용하는 제품의 수조내에 설치하여 장기간 사용하게 되면 물속에 함유되어 있는 각종 미네랄이 시즈히터의 표면에 부착되어 스케일이 생기고 누적이 된다.Therefore, when the above-mentioned sheath heater is installed in a water tank of a product that uses water as a hot water by heating water such as a bathtub, a half body bath, a foot temperature heater, and the like, and is used for a long time, various minerals contained in the water adhere to the surface of the sheath heater and scale. This occurs and accumulates.

이러한 스케일은 열전도를 방해하게 되고 시즈히터의 금속보호관의 부식을 촉진시켜 장기간 사용할 경우에는 습기가 침투하게 되어 다습한 환경요인이 되어 절연저항이 저하되는 관계로 감전과 누전발생의 요인이 되는 위험성이 있었다.These scales hinder heat conduction, promote corrosion of the metal sheathing tube of the sheath heater, and in case of long-term use, moisture penetrates and becomes a humid environment factor, which lowers the insulation resistance. there was.

이러한 누전과 감전의 방지를 위하여 내식성재료를 사용하고 절연성이 오랫동안 유지될 수 있도록 밀봉재를 사용하는 경우도 있으나 특수한 용도로 사용할 경우 즉, 사람의 인체와 직접 면접촉되는 기구이고 또한 전기가 잘 도통하는 물을 인입하여 사용하는 장치인 욕조, 반신욕조, 족온기 등에 사용하는 가열제품의 경우 항시 누전의 우려가 있어 안전성에서의 커다란 문제점을 내재하고 있었다. In order to prevent electric leakage and electric shock, some use corrosion resistant material and sealing material to keep insulation for a long time. However, if it is used for special purpose, it is a device that is in direct surface contact with human body, In the case of a heating product used for a bath, a half-bath, a foot warmer, etc., which draws in water, there is a risk of leakage of electricity at all times.

본 고안은 이러한 종래의 문제점에 착안한 것인바, 본 고안은 2중의 절연구조를 형성한 시즈히터를 제공하기 위한 것으로 이하 본 고안을 첨부된 도면에 의하여 보다 상세히 설명하면 다음과 같다.The present invention is conceived to such a conventional problem, the present invention is to provide a siege heater with a double insulation structure to be described in more detail by the accompanying drawings as follows.

도면에 도시한 바와 같이 단자핀(10)과 연결된 전열선(20)을 피복용 튜브(30)내에 인입한 후 그 사이 공간부에는 절연분말(40)을 충입하고, 튜브(30)의 표면에는 금속보호관(50)을 압착한 구조의 공지된 시즈히터에 있어서,As shown in the drawing, the heating wire 20 connected to the terminal pin 10 is introduced into the covering tube 30, and then the insulating powder 40 is filled in the space therebetween, and the surface of the tube 30 is made of metal. In a known sheath heater having a structure in which the protective tube 50 is crimped,

튜브(30)에 절연성이 양호한 무기절연재로 된 절연층(60)을 형성한 후 이에 상기한 금속보호관(50)을 압착하여 2중의 절연구조를 갖도록 한 것이다.After forming an insulating layer 60 made of an inorganic insulating material having a good insulating property in the tube 30, the metal protective tube 50 is crimped so as to have a double insulating structure.

여기에서 무기절연재로는 세라믹, 마그네시아(산화마그네슘)등이 적합하다.As the inorganic insulating material, ceramic, magnesia (magnesium oxide) and the like are suitable.

이러한 본 고안의 시즈히터는 필요한 용도에 따라 다양한 형상, 모양으로 굴설하여 사용하게 되는데 특히, 요즈음 건강한 생활을 영위하기 위하여는 혈액순환촉진을 우선적으로 생각하게 되는데 이러한 용도로 많이 사용되는 가열구조를 갖는 욕조, 반신욕조, 족온기에 사용할 경우 더욱 효과적이다.The sheath heater of the present invention is used to be bent in various shapes and shapes according to the required use, and in particular, in order to lead a healthy life these days, the blood circulation promoting priority is to be considered. It is more effective when used in bathtubs, half-baths and foot warmers.

즉, 본 고안은 절연분말(40)과 절연층(60)에 의한 2중의 절연구조로 되었기 때문에 물속에 설치하여 사용과정에서 물속에 함유된 각종 미네랄이 부착하여 금속보호관에 스케일이 생기고 누적이 되어 부식작용에 따른 습기의 침투나 다습한 조건이 가해지더라도 무기절연재로 된 절연층(60)에 의하여 완전한 절연작용이 이루어지기 때문에 종래와 같이 감전과 누전의 우려가 전혀 없어 매우 안전하게 시즈히터를 사용할 수 있는 것이다.That is, since the present invention has a double insulating structure by the insulating powder 40 and the insulating layer 60, it is installed in water, and various minerals contained in the water are attached to the metal protective tube during the use process. Even if moisture infiltration or humid conditions are applied, the insulating layer 60 is made of inorganic insulating material so that the insulation is completely performed.Therefore, there is no risk of electric shock or short circuit. It is.

이상에서와 같이 본 고안은 시즈히터를 2중의 절연구조로 형성하였기 때문에 인체와 직접 접촉되는 욕조나 반신욕조, 족온기 등의 제품에 더욱 효과적으로 사용할 수 있는데 금속보호관에 스케일에 의한 부식작용이 생기더라도 열전도가 매우 양호하며 절연저항이 향상되고 절연내력이 높아 누전과 감전의 우려가 전혀 없어 매우 안전하게 물의 가열제품에 널리 사용할 수 있는 유용한 고안인 것이다. As described above, the present invention has a double insulation structure for the sheath heater, so that the present invention can be used more effectively in products such as bathtubs, half-baths, and foot heaters that are in direct contact with the human body. The thermal conductivity is very good, the insulation resistance is improved and the insulation strength is high, so there is no fear of short circuit or electric shock. It is a useful design that can be widely used in water heating products very safely.
