일반적으로, 기온이 낮은 동절기 난방용품이나 성애제거용, 휴대용 발열패드, 도로 융설용, 가전제품의 발열체 등 발열을 요하는 장소나 제품에 면상발열체가 이용되고 있다.In general, a planar heating element is used in a place or a product requiring heat such as a low-temperature winter heating product, defrosting, portable heating pad, road melting, heating element of home appliances.

종래의 면상발열체로 대한민국 실용신안등록출원된 출원번호 제20-2007-0000957호에서 보는바와 같이 면상발열체의 전극부재와 전선의 연결방법을 출원하였으나 면상발열체에서 전극으로 사용되는 금속박과 전선을 연결하는데 있어 절연필름을 벗겨내기 위해 가열된 도구를 사용하여 절연필름에 흠집을 내고 절연필름을 벗겨낸 후 유기용제를 사용하여 필름의 잔여물을 용해 시켜 금속박을 완전히 노출시켜 노출된 금속박에 압착단자나 압착리벳을 직접 연결하도록 면상발열체와 전선의 연결방법을 출원하였다.As a conventional planar heating element, the Korean Utility Model Application No. 20-2007-0000957 filed a method of connecting the electrode member and the wire of the planar heating element as shown in the application, but to connect the metal foil and the wire used as the electrode in the planar heating element To remove the insulation film, use a heated tool to scratch the insulation film, peel off the insulation film, and then use organic solvent to dissolve the residues of the film to expose the metal foil completely to the crimp terminal or crimp on exposed metal foil. A method of connecting a planar heating element and an electric wire is applied to connect the rivet directly.

그러나, 이러한 면상발열체 구조는 동박전극과 전선의 접촉면적을 확보하도록 상기 동박전극의 표면에 강하게 접착되어 있는 코팅지를 완전히 제거하기 위해 고온 열이 가해지는 시공공구를 사용하여 동박전극의 표면을 벗겨낸 후 약품으로 동박전극의 표면을 깨끗이 닦아내야하는 번거로움으로 인해 시공시간이 장시간 소요되어 시공능력이 저하되는 문제점이 있었다.However, the planar heating element structure is stripped of the surface of the copper foil electrode by using a construction tool subjected to high temperature heat to completely remove the coated paper strongly adhered to the surface of the copper foil electrode to secure the contact area between the copper foil electrode and the wire. Due to the hassle of cleaning the surface of the copper foil electrode with chemicals, the construction time takes a long time, there is a problem that the construction capacity is reduced.

따라서 본 고안은 전기한 바와 같은 문제점을 제거코자 안출된 것으로서, 시공시 절단된 면상발열체의 동박전극과 코팅지가 접착이 되지 않도록 동박전극의 상부와 하부에 박리부를 형성시켜 코팅지를 손쉽게 제거할 수 있어 시공시간을 절약하고 상기 동박전극과 전선의 접촉면적을 충분히 확보시켜 안정되게 전원을 공급할 수 있는 면상발열체를 제공하는데 있다.Therefore, the present invention was devised to remove the problems as described above, so that the coated paper can be easily removed by forming a peeling part on the upper and lower portions of the copper foil electrode so that the copper foil electrode and the coated paper of the planar heating element cut during construction are not adhered. The present invention provides a planar heating element which can stably supply power by saving construction time and sufficiently securing the contact area between the copper foil electrode and the electric wire.

상기 목적을 달성하기 위한 본 고안의 면상발열체(100)는, 내열성과 내화학성 및 내충격성을 갖는 절연성베이스원단(102), 저항열에 의해 발열되도록 인쇄형성되는 카본발열부(115), 동박전극으로부터 공급되는 전류를 상기 카본발열부로 전달해주는 실버부(118), 전류를 원거리까지 공급하도록 실버부에 적층되는 동박전극(120), 동박전극의 상부 또는 하부에 형성되는 박리부(130), 상기 절연성베이스원단이 밀폐되도록 합지되는 코팅지(114),로 구성되는 것을 특징으로 한다.The planar heating element 100 of the present invention for achieving the above object, from the insulating base fabric 102 having heat resistance, chemical resistance and impact resistance, the carbon heating unit 115 is formed to be generated by heat of resistance, copper foil electrode The silver part 118 to transfer the supplied current to the carbon heat generating portion, the copper foil electrode 120 stacked on the silver portion to supply the current to a long distance, the peeling portion 130 formed on the upper or lower portion of the copper foil electrode, the insulating Base fabric is coated paper 114, which is laminated so as to be sealed.

면상발열체(100)는 첨부도면에 도시된 구체적인 실시예를 통하여 본고안의 기술내용을 상세히 설명하면 다음과 같다.Planar heating element 100 is described in detail the technical contents of the present invention through the specific embodiment shown in the accompanying drawings.

본 고안의 면상발열체 도면으로, 도 1은 종래의 면상발열체를 보인 도면이 고, 도 2는 본 고안에 따른 면상발열체를 보인 사시도이며, 도 3은 본 고안에 따른 면상발열체를 보인 평면도이고, 도 4는 본 고안에 따른 면상발열체를 보인 저면도이며, 도 5는 본 고안에 따른 면상발열체를 보인 단면도이다.Planar heating element of the present invention, Figure 1 is a view showing a conventional planar heating element, Figure 2 is a perspective view showing a planar heating element according to the present invention, Figure 3 is a plan view showing a planar heating element according to the present invention, Figure 4 is a bottom view showing a planar heating element according to the present invention, Figure 5 is a cross-sectional view showing a planar heating element according to the present invention.

면상발열체(100)은 도2 내지 도5에서 보는바와 같이 절연성베이스원단(102)은 면상발열체에 전원을 통전 시 자체적으로 발생되는 고온열에 견딜 수 있도록 내열성과 장기간 사용을 하기 위해 누전이나 물리적인 충격에 견딜 수 있는 절연성베이스원단(102)을 이용하여야 한다. 상기와 같은 온도에 내열성을 갖는 절연성베이스원단(102)으로는 PET, PE, 폴리우레탄, 에폭시 원단 및 열접착성, 전기절연성, 난연성, 내굴곡성 및 접착제의 흐름성이 균일한 폴리이미드원단 등을 이용할 수 있으며, 가장 바람직하게는 PET를 사용할 수 있다.As shown in FIGS. 2 to 5, the planar heating element 100 has an insulating base fabric 102 that is short-circuit or physically shocked for heat resistance and long-term use to withstand high temperature heat generated when power is supplied to the planar heating element. Insulating base fabric 102 must be used. As the insulating base fabric 102 having heat resistance at the above temperature, PET, PE, polyurethane, epoxy fabric and polyimide fabric having heat adhesiveness, electrical insulation, flame retardancy, flex resistance, and flowability of the adhesive are uniform. It is possible to use, most preferably PET can be used.

이러한 상기 절연성베이스원단(102)에 저항열에 의해 발열기능을 갖도록 일정한 패턴을 유지하여 카본페이스트를 도포하여 건조시켜 카본발열부(115)가 형성된다.The carbon base unit 115 is formed by applying and drying a carbon paste by maintaining a predetermined pattern to have a heat generating function by the heat of resistance to the insulating base fabric 102.

그리고, 실버부(118)는 절연성베이스원단(102)에 인쇄된 카본발열부(115)의 양단 끝에 일정한 간격을 유지하여 인쇄 건조되며, 통전되는 전류를 카본발열부(115)로 접촉저항이 없이 원활히 전달하는 역할을 한다. 상기와 같은 카본발열부(115)와 실버부(118)는 1°카본인쇄와 2°실버인쇄가 상호 바뀌어도 무방하다.The silver part 118 is printed and dried by maintaining a predetermined gap at both ends of the carbon heating part 115 printed on the insulating base fabric 102, and the current flowing through the carbon heating part 115 without contact resistance. It plays a role in delivering smoothly. The carbon heating unit 115 and the silver unit 118 as described above may be interchanged with 1 ° carbon printing and 2 ° silver printing.

한편, 동박전극(120)은 상기 실버부(118)의 상부에 적층시켜 원거리의 카본발열부(115)로 전원을 공급하도록 구성된다.On the other hand, the copper foil electrode 120 is configured to be stacked on top of the silver portion 118 to supply power to the carbon heating unit 115 of the remote.

일반적으로 면상발열체의 전극은 실버부에 동박전극이 적층되는 경우와 본 고안에서는 도시 하지 않았지만 종래의 면상발열체 중 동박전극의 일면에 도전성접착제가 형성된 전극 구조를 형성하고 있다. 이러한 종래의 면상발열체는 도 1에서 보는바와 같이 시공 시 동박전극의 상부에 접착된 코팅지를 제거하기 위해 많은 시간과 노동력을 소비해야 하는 문제점이 있었다.In general, the electrode of the planar heating element forms an electrode structure in which a conductive adhesive is formed on one surface of the copper foil electrode among the planar heating elements, although not shown in the present invention and a copper foil electrode is laminated in the silver part.

인쇄방식은 동박전극(120)과 코팅지(114) 사이 및 동박전극(120)과 실버부(118) 사이에 비접착성잉크를 형성시켜 코팅지(114)와 실버부(118)가 동박전극(120)에 부착되지 않아 면상발열체 시공 시 박리부(130)를 쉽게 제거시켜 시공할 수 있으며, 비인쇄방식은 동박전극의 일면에 형성된 도전성접착제가 전선과 결선되는 부위만 제거된 형태로 구성된다. 또한, 부재부착방식으로는 소정의 두께와 폭을 갖는 도전성부재 또는 비전도성부재를 형성시켜 동박전극(120)이 실버부(118)와 코팅지(114)에 접착되지 않도록 구성할 수 있다. 또한, 박리부(130)는 본 고안에는 예시하지 않았지만 동박전극(120)의 상부 또는 하부 및 카본발열부(115)의 상부 또는 하부에 형성할 수도 있다.The printing method forms a non-adhesive ink between the copper foil electrode 120 and the coated paper 114 and between the copper foil electrode 120 and the silver portion 118 so that the coated paper 114 and the silver portion 118 have the copper foil electrode 120. It is not attached to the surface heating element when the construction can be easily removed by removing the peeling unit 130, the non-printing method is composed of a form in which the conductive adhesive formed on one surface of the copper foil electrode is removed only the portion connected to the wire. In addition, the member attachment method may be configured such that the copper foil electrode 120 is not adhered to the silver part 118 and the coated paper 114 by forming a conductive member or a non-conductive member having a predetermined thickness and width. In addition, although not illustrated in the present invention, the peeling unit 130 may be formed on the upper or lower portion of the copper foil electrode 120 and the upper or lower portion of the carbon heating unit 115.
