The present invention relates to a heat generating fabric structure having an electromagnetic shielding function in which heat generated from a resistor is quickly conducted to a hollow portion and heated to an even temperature throughout the heat generating fabric.

일반적으로 발열직물은 금속(전도성을 지니는 철, 니켈, 구리, 코발트 등) 도금층을 갖는 원단 또는 카본 도전체를 직조한 원단으로서, 원단의 양단에 전극부를 형성하고 전류 통전에 의해 발생하는 방사열을 이용하여 매트, 패드, 침대 매트리스, 보온 이불이나 담요 및 아파트나 일반주택 등의 주거용 난방장치 등에 폭넓게 이용되고 있다. 또한, 추운 야외에서 활동하는 사람들을 위하여 레저용, 방한용 의류로 널리 사용되고 있다.In general, a heat generating fabric is a fabric having a metal (conductive iron, nickel, copper, cobalt, etc.) plating layer or a woven fabric of carbon conductors. It is widely used in mats, pads, bed mattresses, thermal blankets and blankets, and residential heating devices such as apartments and general houses. In addition, it is widely used for leisure and winter clothing for those who work in the cold outdoor.

이와 같은 발열직물은 소정의 크기로 절단되고 양단에 전극부를 형성한 후 전류를 인가하면 원단에 도금 또는 직조된 금속 도전체가 가열되어 열을 발생하게 된다.The heat generating fabric is cut into a predetermined size and forms electrode parts at both ends, and when a current is applied, a metal conductor plated or woven to the fabric is heated to generate heat.

즉, 종래의 발열직물은 전체 면적에 도전체가 도금 또는 직조된 상태를 그대로 사용함으로써 도 6에서와 같이 전극부 양단으로 전류를 인가하면서 전류가 만나는 중앙부분 온도가 가장 높고 그 주변은 항상 온도가 낮은 발열방식이므로, 온도 분포가 불균일하게 형성되는 문제점이 있다.
That is, in the conventional heating fabric, as the conductor is plated or woven in the entire area as it is, as shown in FIG. Since it is an exothermic method, there is a problem in that the temperature distribution is unevenly formed.

따라서, 본 발명은 상술한 종래의 문제점을 해결하기 위한 것으로서, 본 발명의 목적은 금속 도금층을 갖는 원단 또는 카본 도전체를 직조한 원단을 벌집 형태가 되도록 중공부를 가지는 다공구조로 형성하여 저항값을 증가시키고, 도전체에 전류를 인가하면 열기발생이 없는 중공부로 빠르게 열을 전체에 확산시키는 전달방식을 통해 열효율을 증대시킬 수 있는 전자파 차폐기능을 갖는 발열직물 구조를 제공하는 데 있다.
Accordingly, the present invention is to solve the above-mentioned conventional problems, an object of the present invention is to form a porous structure having a hollow portion to form a fabric having a metal plating layer or a woven fabric of a carbon conductor in a honeycomb form to increase the resistance value. The present invention provides an exothermic fabric structure having an electromagnetic shielding function that can increase thermal efficiency through a transfer method in which heat is rapidly diffused to a hollow part without heat generation when an electric current is applied to the conductor.

상기 목적을 달성하기 위한 본 발명의 전자파 차폐기능을 갖는 발열직물 구조는 금속 도금층을 갖는 원단 또는 카본 도전체를 직조한 원단과, 상기 원단에 전극부를 형성하고 상하면에 외피 및 내피를 접착제로 접합하여 전류의 인가시 열을 발생하도록 한 것에 있어서, 상기 원단에 벌집 형태가 되도록 중공부를 천공한 다공구조로 형성하여 저항값을 증가시키고 열기가 중공부호 전달되도록 한 것을 기술적 구성상의 특징으로 할 수 있다.
Heat generating fabric structure having an electromagnetic shielding function of the present invention for achieving the above object is a fabric woven with a fabric or a carbon conductor having a metal plating layer, by forming an electrode portion on the fabric and the upper and lower surfaces by bonding the outer skin and the inner skin with an adhesive In the heat generation when applying the current, it is characterized by the technical configuration that the heat resistance is transmitted to the hollow code to increase the resistance value by forming a porous structure perforated the hollow portion to form a honeycomb in the fabric.

본 발명은 금속 도금층을 갖는 원단 또는 카본 도전체를 직조한 원단에 형성된 벌집 형태의 중공부를 가지는 다공구조에 의해 저항값이 증가되므로 도전체에 전류를 인가하면 발열 온도가 상승됨과 동시에 열기발생이 없는 중공부로 빠르게 열을 전달하여 전체에 확산시키는 전달방식을 통해 열효율을 증대시킬 수 있는 효과가 제공하는 유용한 것이다.
In the present invention, since the resistance value is increased by a porous structure having a honeycomb-shaped hollow portion formed on a fabric having a metal plating layer or a fabric woven with a carbon conductor, when a current is applied to the conductor, the heat generation temperature is increased and there is no heat generation.

이하, 첨부된 도면을 참조하여 본 발명의 바람직한 실시 예를 상세히 설명한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명의 따른 전자파 차폐기능을 갖는 발열직물 구조를 나타낸 평면도, 도 2는 종단면도로서, 부호 1은 원단, 11: 도전체, 12는 중공부, 2는 전극부, 3은 외피, 4는 내피, 5는 접착제를 나타낸다.1 is a plan view showing a heating fabric structure having an electromagnetic shielding function according to the present invention, Figure 2 is a longitudinal cross-sectional view, 1 is a fabric, 11: conductor, 12 is a hollow portion, 2 is an electrode portion, 3 is an outer shell, 4 represents endothelial and 5 represents an adhesive.

상기 원단(1)은 전도성을 지니는 철, 니켈, 구리, 코발트 등의 금속 도금층을 갖는 원단 또는 카본 도전체를 직조한 원단이며, 소정의 크기로 절단하고 양단에 전류를 인가할 수 있도록 전극부(2)를 형성한 후 외피(3) 및 내피(4)를 접착제(5)로 접합하여 발열직물을 만들게 된다. 상기 외피(3)는 부식을 방지하기 위하여 방수원단을 사용하여 수명을 연장할 수 있다. 또한, 상기 전극부(2)에 전류를 공급하기 위해 미도시된 배터리 전원공급용 전선을 접속할 때 통상적인 압착단자 또는 스냅단자 등을 사용하게 된다.The fabric 1 is a fabric having a conductive metal or metal conductor having a metal plating layer of iron, nickel, copper, cobalt, or the like, and is a woven fabric. The electrode 1 may be cut to a predetermined size and apply current to both ends thereof ( 2) after forming the outer shell (3) and the inner shell (4) by the adhesive (5) to make a heat generating fabric. The outer shell 3 may extend the service life by using a waterproof fabric to prevent corrosion. In addition, when connecting the battery power supply wire not shown to supply the current to the electrode unit 2, a conventional crimp terminal or a snap terminal or the like is used.

상기 외피(3) 및 내피(4)는 인조직물, 합성직물 또는 피혁 등 의류에 사용하는 모든 직물 사용이 가능하고, 접착제(5)는 시트형태 또는 스프레이타임의 통상적이 접착소재를 사용하게 된다.The outer skin (3) and the inner skin (4) can be used for all fabrics used in clothing, such as human tissue, synthetic fabric or leather, the adhesive (5) is to use a conventional adhesive material of the sheet form or spray time.

한편, 상기 원단(1)은 도전층을 이루고 있으므로 전자파의 차단이 가능하고, 직류 전원(DC 3V~24V)을 사용하므로 전자파의 발생이 없어 안전하며, 원단(1)에 벌집 형태의 중공부(12)를 천공하여 중공부(12)의 주변이 저항 도전체(11)가 되도록 형성하여 이루어진다.On the other hand, since the fabric 1 forms a conductive layer, electromagnetic waves can be blocked, and since the direct current power source (DC 3V to 24V) is used, no electromagnetic waves are generated and it is safe. 12 is formed so that the periphery of the hollow part 12 is formed into the resistance conductor 11.

먼저, 중공부(12)가 없는 통상적인 원단(1)을 발열직물로 사용하기 위하여 소정의 크기(12㎝ x 18㎝)로 절단한 후 도 4b에서와 같이 저항값을 측정한 결과 1Ω을 나타내고 있다.First, the conventional fabric 1 without the hollow part 12 is cut into a predetermined size (12 cm x 18 cm) in order to use as a heating fabric, and the resistance value is measured as shown in FIG. have.

또한, 본 발명은 원단(1)의 도전체(11)를 벌집 형태로 중공부(12)를 천공 형성한 후 소정의 크기(12㎝ x 18㎝)로 절단하고 도 4a에서와 같이 저항값을 측정한 결과 1.3Ω을 나타냄을 확인할 수 있다. 상기 도전체(11)의 두께(T)는 5㎜이고, 중공부(12)의 폭은 20㎜로 형성하였다. 상기 저항값의 증가는 평균 30%를 나타내고 있으므로 발열온도 상승이 가능하고 이로 인하여 소비전력을 줄일 수 있어 낮은 전압에서도 소망하는 발열을 구현할 수 있는 것이다.In addition, the present invention is formed by punching the hollow portion 12 in the form of a honeycomb of the conductor 11 of the fabric 1 and cut it to a predetermined size (12 cm x 18 cm) and the resistance value as shown in Figure 4a As a result, it can be seen that 1.3Ω is shown. The thickness T of the conductor 11 was 5 mm, and the width of the hollow part 12 was 20 mm. Since the increase in the resistance value represents an average of 30%, it is possible to increase the heating temperature, thereby reducing the power consumption, so that the desired heating can be realized even at a low voltage.

다음으로 DC 3.7V의 전류를 사용하여 측정한 결과 중공부(12)가 형성되지 않은 기존의 원단(1)은 도 6에서와 같이 중앙부분의 온도가 31.5도이고 주변은 28~29도를 나타내고 있음을 확인할 수 있고, 동일 크기의 도전성 원단(1)에 벌집 형태로 중공부(12)를 천공 형성한 본 발명의 원단(1)은 도 5에서와 같이 37~38도로 고르게 온도가 분포됨이 확인됨은 물론 기존 보다 7~9도가 상승되고 있음을 확인할 수 있다.Next, as a result of measuring using a current of DC 3.7V, the existing fabric 1, in which the hollow part 12 is not formed, has a temperature of 31.5 degrees in the center and 28-29 degrees in the periphery as shown in FIG. It can be confirmed that, the fabric 1 of the present invention formed the perforated hollow portion 12 in a honeycomb form on the conductive fabric 1 of the same size is evenly distributed temperature 37 to 38 degrees as shown in FIG. Of course, it can be confirmed that the 7 ~ 9 degree is higher than the existing one.

즉, 원단(1)에 벌집 형태의 중공부(12)를 형성하면 저항값이 증가됨은 물론 온도가 상승되고 고른 온도 분포를 발휘하고 있음이 확인된다.That is, when the hollow portion 12 in the honeycomb form on the fabric 1, it is confirmed that the resistance value is increased, as well as the temperature is increased and the temperature distribution is even.

상기 원단(1)에 고른 온도 분포를 나타내는 것은 도 2의 요부확대 도면에서와 같이 도전체(11)에서 발생하는 온열이 비발열부분인 중공부(12)의 온도가 낮은 중앙부분으로 빠르게 열전도가 이루어지므로 원단(1)의 전체에 분포된 중공부(12)에 고르게 열전달이 이루어지기 때문이다.The even temperature distribution in the fabric 1 is shown in the enlarged view of the main portion of FIG. It is because the heat transfer is evenly made to the hollow portion 12 distributed over the entire fabric (1).

상기 중공부(12)는 벌집 형태의 육각형 형태뿐만 아니라 도 3에서와 같이 원형, 오각형, 사각형 및 삼각형 등 다양한 형태가 가능함을 밝혀둔다.The hollow part 12 is not only hexagonal form of honeycomb form, but also reveals that various forms such as circular, pentagonal, square, and triangle as shown in FIG.

상기와 같이 벌집 형태의 중공부(12)를 형성한 다공구조를 가지는 도전성 원단(1)은 저항값이 증가되므로 도전체에 전류를 인가하면 발열 온도가 상승됨과 동시에 열기발생이 없는 중공부(12)로 빠르게 열을 전달하여 전체에 확산하는 전달방식이므로 열효율을 증대시킬 수 있는 것이다. Since the conductive fabric 1 having the porous structure in which the hollow portion 12 having the honeycomb form is formed as described above, the resistance value is increased, and when the current is applied to the conductor, the heat generation temperature increases and the hollow portion 12 does not generate heat. It is a transfer method that spreads heat quickly by transferring heat to), which can increase thermal efficiency.
