Description

직조 유연 면상 발열체 {Flexible planar heating element which is woven}[0001] The present invention relates to a flexible planar heating element,

본 발명은 직조 유연 면상 발열체에 관한 것으로, 더욱 상세하게는 유연성을 가지는 선상의 금속발열섬유를 포함하는 섬유부재를 경사 및 위사로 사용하여 직조한 직조 유연 면상 발열체에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a woven soft surface heating element, and more particularly, to a woven soft flexible surface heating element woven using a fibrous material containing flexible metal wire fibers as warp and weft.

전기 또는 가스로부터의 에너지를 열에너지로 변환시키는 발열체는 일반적으로 금속 또는 세라믹 선으로 만들어진 선상 발열체, 흑연과 같은 벌크 발열체 및 평면 전극 위에 막상으로 발열체가 코팅된 면상발열체로 구분된다. 이 중 면상발열체는 평면상의 금속전극 위에 금속, 세라믹 또는 탄소계 발열층이 코팅되어 있고, 상기 발열층의 상부 및 하부를 절연체로 실링하는 구조로 되어있다. Generally, a heating element that converts energy from electricity or gas into heat energy is divided into a linear heating element made of metal or ceramic wire, a bulk heating element such as graphite, and a plane heating element coated with a heating element on a flat electrode. In the planar heating element, a metallic, ceramic or carbon-based heating layer is coated on a planar metal electrode, and the upper and lower portions of the heating layer are sealed with an insulator.

최근 상기와 같은 면상 발열체를 평면이 아닌 곡면을 형상을 가지거나, 사용 중 유연하게 휘어질 수 있는 유연 면상발열체를 제조할 필요성이 대두되고 있다. 그러나 면상발열체를 지닌 기판의 유연성 부족, 기판에 코팅된 발열물질의 유연성에 한계가 있기 때문에 유연성을 갖도록 제작하게 되면 제작시 균열이나 성능 열하가 일어난다. 또는 발열물질이 취성이 있어 쉽게 깨어지거나, 망상의 기판을 사용하여 내부에 발열물질을 채울 때 발열 특성에 문제가 발생하게 된다. In recent years, there has been a need to manufacture a flexible surface heating element having a curved surface shape, which is not a flat surface, and which can flex flexibly during use. However, since there is a limit to the flexibility of the substrate having the surface heating element and the flexibility of the heating material coated on the substrate, cracking or performance deterioration occurs when the substrate is manufactured with flexibility. Or the heat generating material is brittle and is easily broken or a problem occurs in the heat generating characteristic when the substrate is used to fill the inside with the heat generating material.

예를 들면 면상발열체로 기대되는 탄소계 전극의 경우 고온에 산화되며 취성이 있어 충격에 의해 쉽게 균열이 발생하는 문제로 인해 장기간 사용이 용이하지 못하다. 또한 원적외선 세라믹계 발열체를 금속기판 위에 코팅하여 만든 경우 세라믹 발열체의 휘어짐 한계로 인해 면상발열체의 휘어짐이 클 경우 사용이 불가능하다.For example, a carbon-based electrode expected to be a surface heating element is not easily used for a long period of time due to a problem that it is oxidized at high temperature and is brittle and easily cracked due to impact. In addition, when a far infrared ray ceramic heat generating body is coated on a metal substrate, it can not be used when the bending of the surface heat generating body is large due to the warping limit of the ceramic heat generating body.

이를 극복하기 위해 전도성이 있는 물질을 선상으로 만들어 이를 직조하여 면상의 발열체를 제조하는 기술이 알려져 있다. 이와 같은 종래의 면상발열체는 종래기술 '대한민국특허청 공개특허 제10-2008-0090068호 면상발열체와 그 물성구조 및 제조방법'과 같이 일반섬유와 금속섬유를 함께 꼬아서 만든 직조용 실을 사용하여 면상 발열체를 직조하는 발명이 알려져 있다. 이 이외에도 '대한민국특허청 등록실용신안 제20-2005-0011304호 면사직조발열체'와 같이 전도성이 없는 폴리머실 표면에 전도성이 있는 카본을 코팅하여 전도성을 부여한 면상 발열체 기술이 알려져 있다.In order to overcome this problem, there is known a technique for manufacturing a surface heating element by weaving a conductive material into a line. Such a conventional surface heating element may be formed by using a woven fabric made by twisting a common fiber and a metal fiber together, as in the prior art 'Korean Patent Application No. 10-2008-0090068 Surface Heating Element and Its Physical Structure and Manufacturing Method' An invention is known in which a heating body is woven. In addition, there is known a surface heating element technique in which conductivity is imparted by coating conductive carbon on the surface of a non-conductive polymer seal, such as "Korean Utility Model Registration Utility Model No. 20-2005-0011304".

이와 같은 종래의 기술들은 금속선 자체를 직조할 수 없기 때문에 일반섬유와 금속섬유를 함께 꼬아 직조용 실을 제작하거나, 전도성이 없는 폴리머 실의 표면에 금속을 코팅한 후 이를 직조하여 면상발열체를 제조한다. 하지만 이러한 방법으로 면상 발열체를 직조할 경우 면상 발열체가 유연하지 못한 뿐만 아니라 제조 공정이 복잡하고 제조 비용이 증가한다는 문제점이 있다.Since the metal wires themselves can not be woven by such conventional techniques, a plain yarn is produced by twisting a plain fiber and a metal fiber together, or a metal is coated on the surface of a polymer chamber having no conductivity and then woven to produce a planar heating element . However, when the planar heating element is woven by this method, the planar heating element is not flexible, and the manufacturing process is complicated and the manufacturing cost is increased.

따라서 본 발명의 목적은 선상의 금속발열섬유를 경사 및 위사로 직조하여 제조 공정이 간단하고 제조 비용이 절감되는 직조 유연 면상 발열체를 제공하는 것이다.Accordingly, it is an object of the present invention to provide a woven flexible heat generating element in which the manufacturing process is simple and the manufacturing cost is reduced by weaving linear heating metal fibers in warp and weft.

이하 도면을 참고하여 본 발명에 따른 직조 유연 면상 발열체를 상세히 설명한다.BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, a woven flexible surface heating element according to the present invention will be described in detail with reference to the drawings.

도 1 및 도 2a에 도시된 바와 같이 제1실시예에 따른 직조 유연 면상 발열체(100)는 중앙영역에 금속발열섬유층(110)이 형성되며, 금속발열섬유층(110)의 상부 및 하부에는 각각 절연섬유층(130)이 적층된다.As shown in FIGS. 1 and 2A, a woven soft-surface heating element 100 according to the first embodiment has a metal heating fiber layer 110 formed at a central region thereof, The fibrous layer 130 is laminated.

금속발열섬유층(110)은 발열을 일으키는 금속을 얇은 선상으로 제조한 금속발열섬유(111)를 경사 및 위사로 사용하여 직조하여 형성된다. 금속발열섬유층(110)을 구부릴 때 금속발열섬유층(110)을 구부리는 힘에 의해 금속발열섬유(111)가 끊어지지 않도록 금속발열섬유층(110)을 직조한다. 유연한 금속발열섬유층(110)에 의해 직조 유연 면상 발열체(100)는 필요에 따라 구부려 사용할 수 있다. 금속발열섬유(111)는 한 가닥의 섬유를 이용하여 직조할 수 있으며, 필요에 따라서 도 3a와 같이 복수의 금속발열선을 연선한 금속발열섬유(111)를 이용하여 직조를 수행할 수 있다.The metal heating fiber layer 110 is formed by weaving the metal heating fiber 111, which is made of thin metal wire, which generates heat, as warp and weft. When the metal heating fiber layer 110 is bent, the metal heating fiber layer 110 is woven so that the metal heating fiber 111 is not broken by the bending force of the metal heating fiber layer 110. The flexible soft surface heat emission body 100 can be bent and used as needed by the flexible metal heat generation fiber layer 110. The metal heating fibers 111 may be woven using one strand of fibers. If necessary, the metal heating fibers 111 may be woven using a plurality of metal heating wires as shown in FIG. 3A.

여기서 금속발열섬유(111)는 백금(Pt), 철(Fe), 니켈(Ni), 알루미늄(Al), 구리(Cu), 티타늄(Ti), 몰리브덴(Mo), 금(Au), 은(Ag), 팔라듐(Pd), 류테늄(Ru), 마그네슘(Mg), 크롬(Cr), 아연(Zn), 텅스텐(W), 코발트(Co)로만 이루어지거나 이들 중 적어도 둘 이상을 포함한 합금이 될 수 있다. 이 이외에도 선상으로 제작 가능한 모든 금속을 적용 가능하다.Here, the metal heating fiber 111 may be made of platinum (Pt), iron (Fe), nickel (Ni), aluminum (Al), copper (Cu), titanium (Ti), molybdenum Ag, Pd, Ru, Mg, Cr, Zn, W, and Co, or an alloy containing at least two of these elements, . In addition to this, it is possible to apply all metals that can be produced on board.

도 3b에 도시된 바와 같이 금속발열섬유(111)의 재료가 구리, 니켈, 크롬 등과 같이 고온에서 산화되는 금속의 경우에는 산화방지를 위해 금속발열섬유층(110)의 외주면에 산화방지막(113)이 코팅된다. 산화방지막(113)의 코팅은 금속발열섬유층(110)을 직조한 후 코팅할 수도 있지만, 직조되기 전의 금속발열섬유(111)에 코팅을 한 후 직조를 수행할 수도 있다.3B, in the case where the material of the metal heating fiber 111 is a metal oxidized at a high temperature such as copper, nickel, chromium or the like, an oxidation preventing film 113 is formed on the outer circumferential surface of the metal heating fiber layer 110 Coated. The coating of the oxidation preventing film 113 may be performed after the metal heating fiber layer 110 is woven. Alternatively, the metal heating fiber 111 may be coated before the weaving.

절연섬유층(130)은 금속발열섬유층(110)의 상부 및 하부에 배치되어 금속발열섬유층(110)으로부터의 열을 절연시키는 역할을 한다. 절연섬유층(130)은 절연재질로 이루어진 절연섬유(131)를 경사 및 위사로 사용하여 직조 과정을 통해 형성된다.The insulating fiber layer 130 is disposed at upper and lower portions of the metal heating fiber layer 110 to insulate heat from the metal heating fiber layer 110. The insulating fiber layer 130 is formed through a weaving process using the insulating fibers 131 made of an insulating material as warp and weft.

여기서 절연섬유(131)는 세라믹계 섬유인 것이 바람직하며, 상세하게는 유리 섬유, 내열 폴리머 섬유, 산화티타늄 섬유, 산화알루미늄 섬유, 산화지르코늄섬유, 탄화규소 섬유, 티타늄산칼륨 섬유 중 적어도 어느 하나인 것이 바람직하다. 이 이외에도 절연성을 갖는 나노 섬유 또는 천연 섬유를 통해 절연섬유층(130)을 직조 가능하다.The insulating fiber 131 is preferably a ceramic fiber, and more specifically, at least one of glass fiber, heat-resistant polymer fiber, titanium oxide fiber, aluminum oxide fiber, zirconium oxide fiber, silicon carbide fiber and potassium titanate fiber . In addition, the insulating fiber layer 130 can be woven through nanofibers or natural fibers having insulating properties.

이와 같은 재료로 직조된 금속발열섬유층(110) 및 절연섬유층(130)을 결합시키는 방법으로는 금속발열섬유층(110)과 절연섬유층(130) 사이에 접착제를 도포하여 결합하거나, 금속발열섬유층(110)과 절연섬유층(130)을 재봉 기계(Sewing machine)를 통해 재봉하여 결합시킨다. 결합방법은 이에 한정되지 않고 다양한 방법을 사용 가능하다.As a method for bonding the metal heating fiber layer 110 and the insulating fiber layer 130 woven with such a material, an adhesive may be applied and bonded between the metal heating fiber layer 110 and the insulating fiber layer 130, And the insulating fiber layer 130 are sewed together through a sewing machine. The bonding method is not limited thereto and various methods can be used.

도 2b에 도시된 바와 같이 제2실시예에 따른 직조 유연 면상 발열체(200)는 제1실시예의 직조 유연 면상 발열체(100)와 비교하여 금속발열섬유층(210)과, 절연섬유층(230)은 유사하지만 전극섬유층(250)을 더 포함한다는 점에서 차이가 있다.2B, the woven soft-surface heating element 200 according to the second embodiment is different from the woven soft-surface heating element 100 according to the first embodiment in that the metal heating fiber layer 210 and the insulating fiber layer 230 are similar to each other However, there is a difference in that the electrode fiber layer 250 is further included.

전극섬유층(250)은 전기를 공급가능한 전극섬유(251)를 경사 및 위사로 사용하여 직조한 층으로, 금속발열섬유층(210)과 절연섬유층(230)의 사이에 배치된다. 전극섬유층(250)은 외부의 전기공급장치와 연결되어 전기를 공급하는 역할을 하며, 금속발열섬유층(210)의 저항이 높아져 온도가 너무 올라가게 되면 전극섬유층(250)을 통해 온도를 제어 가능하다. 경우에 따라서 도 3c와 같이 전극섬유(251)와 금속발열섬유(211)를 각각의 층으로 배치시키지 않고 금속발열섬유(211)와 전극섬유(251)를 연선한 다음에 이를 금속발열섬유층(210)으로 직조할 수 있다.The electrode fiber layer 250 is a woven layer formed by using an electrode fiber 251 capable of supplying electricity as warp and weft, and is disposed between the metal heating fiber layer 210 and the insulating fiber layer 230. The temperature of the electrode fiber layer 250 can be controlled through the electrode fiber layer 250 when the temperature of the electrode fiber layer 250 is too high as the resistance of the metal heating fiber layer 210 increases. . The metal heating fibers 211 and the electrode fibers 251 are connected to each other without arranging the electrode fibers 251 and the metal heating fibers 211 as separate layers as shown in FIG. ).

전극섬유층(250)은 제1실시예의 금속발열섬유층(110) 및 절연섬유층(130)의 결합과 마찬가지로 접착제를 이용하여 적층되거나, 재봉 기계를 통해 재봉될 수 있다.The electrode fiber layer 250 may be laminated using an adhesive as in the case of the combination of the metal heating fiber layer 110 and the insulating fiber layer 130 of the first embodiment, or may be sewn through a sewing machine.

도 2c 및 도 4에 도시된 바와 같이 제3실시예에 따른 직조 유연 면상 발열체(300)는 제2실시예에 대해 복수의 절연섬유층(330) 사이에 금속발열섬유층(310)과 전극섬유층(350)이 적층된다는 점은 유사하나 면상 발열체(300)의 내부에 발열충진제(370)가 추가된다는 점은 차이가 있다.As shown in FIG. 2C and FIG. 4, the woven flexible non-phase heating element 300 according to the third embodiment has a structure in which the metal heating fiber layer 310 and the electrode fiber layer 350 But it is different in that the exothermic filler 370 is added to the inside of the planar heating element 300.

발열충진제(370)는 각 섬유가 직조된 금속발열섬유층(310) 및 전극섬유층((350))에서 직조된 섬유 사이의 공간에 충진되어 발열한다. 이와 같은 발열 충진제(370)를 추가하게 되면 발열 성능이 향상될 뿐만 아니라 기계적 내구성 또는 전기적 특성을 향상시킬 수 있다. 경우에 따라서 별도의 금속발열섬유층(310)을 구비하지 않고 절연섬유층(330)과 전극섬유층(350)으로만 이루어진 직조 유연 면상 발열체(300)에 발열충진제(370)를 추가하여 발열기능을 수행하도록 할 수 있다.The exothermic filler 370 is filled in the spaces between the fibers woven in the metal heating fiber layer 310 and the electrode fiber layer 350 in which the respective fibers are woven to generate heat. Adding such a heat generating filler 370 not only improves the heat generating performance but also improves the mechanical durability or electrical characteristics. A heat generating filler 370 may be added to the woven flexible heat generating element 300 made of only the insulating fiber layer 330 and the electrode fiber layer 350 without a separate metal heating fiber layer 310 to perform a heat generating function can do.

여기서 발열충진제(370)는 탄소계인 흑연, 탄소나노튜브(CNT), 활성탄소, 카본블랙이나, 비탄소계인 탄화규소(SiC), 규화몰리브덴(MoSi2), 이산화주석(SnO2) 중 적어도 어느 하나를 사용하는 것이 바람직하다.Wherein at least any one of heating filler 370 carbon sealed graphite, carbon nanotubes (CNT), activated carbon, carbon black or, sorbitan Subtotal silicon carbide (SiC), silicide molybdenum (MoSi 2), dioxide, tin (SnO 2) It is preferable to use one.

제1 내지 3실시예와 같이 각각의 섬유로 이루어진 섬유층(110, 130, 210, 230, 250, 310, 330, 350)을 적층시켜 직조 유연 면상 발열체(100, 200, 300)를 제조할 경우 용도에 따라서 적층되는 층의 수를 변경시킬 수 있으며, 제작 공정이 간단하다. 직조 유연 면상 발열체(100, 200, 300)는 이러한 순서 이외에도 선상으로 형성된 금속발열섬유와, 금속발열섬유의 상부 및 하부에 배치되는 선상의 절연섬유를 갖는 섬유부재를 제조하고, 섬유부재를 경사 및 위사로 사용하여 직조 유연 면상 발열체를 직조할 수도 있다.When the woven soft surface heaters 100, 200 and 300 are manufactured by laminating the fibrous layers 110, 130, 210, 230, 250, 310, 330 and 350 made of the respective fibers as in the first to third embodiments It is possible to change the number of layers to be laminated according to the manufacturing method, and the manufacturing process is simple. In addition to the above-mentioned steps, the woven flexible heat generating elements 100, 200, and 300 further include a metal heating fiber formed in a linear shape and a fiber member having linear insulating fibers disposed on upper and lower portions of the metal heating fiber, It is also possible to use woven fabrics to weave flexible surface heating elements.

상기와 같이 선상의 섬유로 직조 유연 면상 발열체(100, 200, 300)를 직조하게 되면 발열체(100, 200, 300)가 유연하게 제조되기 때문에 필요에 따라서 발열체(100, 200, 300)를 구부릴 수 있다. 예를 들면 야외에서 음식을 조리할 때 판상의 발열체를 사용하게 되면 조리기구의 하부만 가열되어 가열하는 데 시간이 많이 걸리는 단점이 있다. 하지만 본 발명과 같은 유연한 발열체(100, 200, 300)를 사용하게 되면 조리기구의 둘레를 둘러싸도록 배치한 다음 발열되게 하여 음식을 조리하기 용이하다. 또한 본 발명의 발열체(100, 200, 300)는 기존의 면상 발열체와 같이 일반섬유와 금속섬유를 함께 꼬아 직조용 실을 제작하거나, 전도성이 없는 폴리머 실의 표면에 금속을 코팅한 후 이를 직조하는 방법이 아닌 발열금속섬유 자체를 직접 직조하기 때문에 제조 공정이 간단하고 제조 비용이 절감되는 효과를 제공한다.Since the heating elements 100, 200 and 300 are fabricated by the weaving of the woven flexible non-heating elements 100, 200 and 300 with the linear fibers as described above, the heating elements 100, 200 and 300 can be bent have. For example, when a plate-shaped heating element is used to cook food in the outdoors, only the lower portion of the cooking device is heated and takes a long time to heat. However, if the flexible heating elements 100, 200, 300 according to the present invention are used, they are arranged so as to surround the periphery of the cooking utensil and then heated to facilitate cooking. In addition, the heating elements 100, 200, and 300 of the present invention may be fabricated by twisting common fibers and metal fibers together to form a fabric for weaving, or by coating a metal on the surface of a non- Since the heat-generating metal fiber itself is directly woven instead of the method, the manufacturing process is simple and the manufacturing cost is reduced.
