Abstract

PURPOSE: A positive temperature coefficient electric field and magnetic field cut off heating element is provided to prevent over-heating and a fire electric shock accident. CONSTITUTION: A first conductor(1) and a second conductor(2) are formed in the inner side of PTC(Positive Temperature Coefficient) heating part(3) of a circular shape. The first conductor and the second conductor are not connected. Temperature of PTC material between the first conductor and the second conductor arrives to a fixed value by a resistance value. Conductivity is diminished according to the increase of resistivity of the PTC material. The temperature of the PTC material is maintained by controlling the flow of a current. Two magnetic fields of circular waveform created in the first conductor and the second conductor are canceled inside the PTC heating part. An insulated coating(4) is formed on the outer circumference of the PTC heating part.

전자파 전기장 및 자기장 차단 PTC 발열체선{ PTC ELECTRIC HEATING CORD FOR REDUCED EMF AND EF EMISSION }PTC ELECTRIC HEATING CORD FOR REDUCED EMF AND EF EMISSION}

본 발명은 PTC (정 온도 계수 positive temperature coefficient) 발열선을 이용하여 국부과열, 화재, 감전사고 등을 방지하며 또한 PTC 발열선에서 발생되는 전자파 전기장 및 자기장을 차단하는 PTC 발열선에 관한 것이다.The present invention relates to a PTC heating wire that prevents local overheating, fire, electric shock, etc. by using a PTC (positive temperature coefficient) heating wire and also blocks electromagnetic and magnetic fields generated from the PTC heating wire.

일반적으로 발열선은 여러 종류가 있는데 동과 닉켈 합금선으로 발열하는 발열체선 그리고 면상 발열체, PTC 발열선이 있는데 그중에서 면상발열체와 동과 닉켈 합금선을 이용하여 발열하는 발열체선에서 발생하는 전기장 및 자기장을 차단하는 특허는 본 출원인의 특허등록 외에 여러개의 특허가 등록 공보 되어 있으나 PTC 발열선을 이용한 전기장 및 자기장 차단한 특허는 전무한 실정이다.In general, there are several types of heating wires, which include heating element wires that generate copper and nickel alloy wires, and planar heating elements and PTC heating wires. In addition to the patent registration of the applicant, a number of patents are registered and published, but there are no patents for blocking electric and magnetic fields using PTC heating wires.

본발명은 상술한 문제점을 해결하기 위한 것으로 본 출원인이 전자파 자기장 차단 발열체선에 대하여 1998년 12월18일에 특허 등록 공보(10-0184360 전자파(EMW.EMF)를 발생하지 않는 발열체선과 또한 전기장 차단 특허 등록공보(10-0184359 전자파 흡수 제거 및 어스 확인 회로)되었으나 상기의 본 출원인의 특허 자기장 차단 발열체선은 구리 닉켈 합금선을 이용하여 전자파 자기장을 차단하는 특징이 있으나 발열체선이 발열만 하고 발열선이 자체적으로 온도를 제어하지 못하기 때문에 온도를 제어하여 주는 온도조절기의 고장이나 오작동 으로 인하여 과열로 인한 화상과 화재의 위험성이 있어 본 발명은 PTC (양 온도계수 positive temperatural coefficient)자기 제어식 발열선으로 온도 상승에 비례한 저항값의 증가로 일정한 설정온도를 유지 발열하면서 전자파 자기장을 차단하고, 또한 PTC 발열부에서 발생하는 전기장을 차단하는 목적이 있다.The present invention has been made to solve the above-mentioned problems, and the applicant has not registered a patent on December 18, 1998 with respect to the electromagnetic field shielding heating element wire (10-0184360 heating element wire and also the electric field blocking). Although the patent registration publication (10-0184359 electromagnetic wave absorption removal and earth confirmation circuit), the applicant's patent magnetic field blocking heating element wire is characterized by blocking the electromagnetic magnetic field by using copper nickel alloy wire, but the heating element wire only generates heat and the heating wire is There is a risk of burns and fire due to overheating due to the failure or malfunction of the temperature controller that controls the temperature because the temperature cannot be controlled by itself. The present invention provides a PTC (positive temperatural coefficient) self-regulating heating wire. Maintain constant temperature by increasing resistance value proportional to To block the electric field generated by the PTC heating unit.

이러한 목적을 달성하기 위하여 본 발명은 도3과 같이 2개의 도체에 원형의 PTC 발열부(3)를 피복하여 자기장을 차단함에 있어서 도체1(1)과 도체2(2)는 서로 대칭되어 있고 도체1과 도체2 사이에서 PTC 발열부에서 발열 하게 되며 PTC 발열부(3)의 저항값에 의하여 온도가 결정되며, 이때에 도체1과 도체2에 전류가 흐르면서 각각의 도체의 선 에서 각 도체의 축을 중심으로 원형 파장의 자기장이 발생하기 때문에 원형의 PTC 발열부 내에서 자기장이 서로 상쇄되어 자기장을 상쇄하여 PTC 발열부(3)에서 발생하는 자기장을 차단하는 것이다.In order to achieve the above object, in the present invention, the conductor 1 (1) and the conductor 2 (2) are symmetrical with each other and the conductors are shielded from each other by covering the circular PTC heating part 3 on the two conductors as shown in FIG. Between the 1 and the conductor 2 is generated in the PTC heating unit, the temperature is determined by the resistance value of the PTC heating unit (3), at this time, the current of the conductor 1 and the conductor 2 flows the axis of each conductor in the line of each conductor Since the magnetic field of the circular wavelength is generated at the center, the magnetic fields cancel each other in the circular PTC heating unit to cancel the magnetic field to block the magnetic field generated in the PTC heating unit 3.

그리고 PTC 발열부(3) 외부에 절연 피복을 하고 은박지,알루미늄포일(5) 또는 금속 쉴드 ,도전성 망체(5)를 접지(ground) 또는 교류의 -단(내추럴 natural)에 연결하여 PTC 발열부(3)에서 발생하는 전기장을 접지로 흘려보내 전기장을 차단하는 것이다.Then, the insulation layer is coated on the outside of the PTC heating unit 3, and the PTC heating unit is connected by connecting the silver foil, the aluminum foil 5 or the metal shield, and the conductive mesh 5 to ground or alternating current (natural). The electric field generated in 3) is flowed to ground to cut off the electric field.

이와같이 PTC (정온도 계수 positive temperature coefficient)발열선을 이용하여 기존의 발열선에서 과열방지와 화재 감전 사고를 방지하기위해 필요로 하는 바이메탈과 온도센서가 필요치 않고 또한 온도 조절기 부품을 최소화 할 수 있어 부품비용 및 원재료 절감은 물론 PTC 발열선 또한 간단한 3공정으로 저렴하게 생산할수 있는 것이다. 그리고 PTC 발열선에서 발생하는 전자파 전기장 및 자기장을 완전 차단하여 인체에 영향을 미치지 않는 효과가 있는 것이다.As such, the PTC (positive temperature coefficient) heating wire eliminates the need for bimetals and temperature sensors to prevent overheating and fire shock in existing heating wires, and minimizes the temperature controller components. In addition to saving raw materials, PTC heating wires can also be produced at low cost in three simple steps. In addition, the electromagnetic wave and the magnetic field generated by the PTC heating wire are completely blocked so that the human body is not affected.
