There was a problem.

본 발명은 상술한 바와 같은 종래 침구류용 무자계 발열선의 문제점을 해소하기 위하여 안출된 것으로, 히터코일의 단락을 효과적으로 방지할 수 있고 굵기가 가늘며 생산성은 높고 제조원가는 저렴한 침구류용 무자계 발열선을 제공하는데 그 목적이 있다.The present invention is devised to solve the problems of the conventional bedding-type non-magnetic heating wire as described above, can effectively prevent the short circuit of the heater coil and provide a non-magnetic heating wire for bedding, which is thin and high productivity and inexpensive manufacturing cost. The purpose is.

본 발명에 따른 침구류용 무자계 발열선은, 중심의 심실; 상기 심실의 외주면에 서로 평행하게 나선형으로 권선되고, 각 일단이 전기적으로 연결된 상태에서 각 타단이 전원의 (+)(-)단자에 각각 연결되는 2 가닥의 히터코일; 상기 심실 외주에 피복되어 상기 히터코일을 차폐 절연하는 외부절연체를 포함하여 이루어지는 것을 특징으로 한다.Magnetic field heating wire for bedding according to the present invention, the central ventricle; Two strands of heater coils spirally wound in parallel to each other on the outer circumferential surface of the ventricle and each other end is connected to a (+) (-) terminal of a power source while each end is electrically connected; And an outer insulator coated on the outer periphery of the ventricle to shield and insulate the heater coil.

위 구성에 있어서, 상기 히터코일의 외주면에는 고온 폴리미드 재질의 절연용 에나멜층이 코팅되는 것이 바람직하며, 또한, 상기 내부절연체 외주면에 권선되는 금속쉴드와, 상기 내부절연체 외주면에 피복되어 상기 금속쉴드를 차폐 절연하는 외부절연체 등이 더 포함되어 구성될 수 있다.In the above configuration, it is preferable that an insulating enamel layer made of high temperature polyimide is coated on the outer circumferential surface of the heater coil, and further, a metal shield wound around the outer circumferential surface of the inner insulator and the outer surface of the inner insulator, wherein the metallic shield is coated. It may be configured to further include an external insulator for shielding and insulating.

이하, 바람직한 실시예를 통하여 본 발명에 따른 침구류용 무자계 발열선의 구성과 작용을 보다 구체적으로 살펴본다.Hereinafter, the configuration and operation of the bedless heating wire for bedding according to the present invention through the preferred embodiment in more detail.

도 1은 본 발명의 일 실시예에 따른 따른 침구류용 무자계 발열선의 구성도이고, 도 2는 그 횡단면도이다.1 is a block diagram of a magnetic field heating wire for bedding according to an embodiment of the present invention, Figure 2 is a cross-sectional view thereof.

도시된 바와 같이, 본 발명의 일 실시예에 따른 침구류용 무자계 발열선은, 폴리에스터 등으로 이루어진 심실(1), 심실(1)의 외주면에 어느 한 방향으로 길이방향을 따라 2중 나선형으로 감겨진 두 가닥의 히터코일(2,3), 상기 히터코일(2,3)이 감겨진 심실(1) 외주면에 피복되어 히터코일(2,3)를 차폐하는 내부절연체(4), 상기 내부절연체(4) 외주면에 권선되는 금속쉴드(5), 그리고, 내부절연체(4) 위에 피복되어 상기 금속쉴드(5)를 차폐하는 외부절연체(6) 등으로 이루어져 있다.As shown, the magnetic field heating wire for bedding according to an embodiment of the present invention is wound in a double spiral along the longitudinal direction in any direction on the outer circumferential surface of the ventricle 1, the ventricle 1 made of polyester, etc. Two inner strands of heater coils 2 and 3, an inner insulator 4 covering the outer circumferential surface of the ventricle 1 on which the heater coils 2 and 3 are wound, and shielding the heater coils 2 and 3, the inner insulator (4) A metal shield 5 wound on an outer circumferential surface, and an outer insulator 6 covering the inner insulator 4 to shield the metal shield 5, and the like.

상기 히터코일(2,3)은 도 3에 도시된 바와 같은 원형이나 또는 장방형 단면을 갖도록 구성될 수 있으며, 그 외주면에는 내열성, 내구성 및 절연성을 높일 수 있는 에나멜층(2a,3a)이 코팅된다. 이들 히터코일(2,3)은 도 1 및 도 5에 나타난 바와 같이 코일(2)은 심실(1) 외주면에 서로 나란히 배열되도록 2 중 나선형으로 감겨진 후 각 일단이 서로 연결되고(P) 다른 쪽 끝단이 전원(10)의 (+)(-)단자에 각각 연결됨으로써 서로 전류의 방향이 반대가 되도록 전기적으로 연결된다.The heater coils 2 and 3 may be configured to have a circular or rectangular cross section as shown in FIG. 3, and enamel layers 2a and 3a are coated on the outer circumferential surface thereof to increase heat resistance, durability, and insulation. . These heater coils 2 and 3 are wound in a double spiral so that the coils 2 are arranged in parallel with each other on the outer peripheral surface of the ventricle 1 as shown in FIGS. One end is electrically connected to each other so that the directions of currents are reversed by being connected to the (+) (-) terminals of the power supply 10, respectively.

이와 같은 본 발명의 일 실시예에 따른 침구류용 무자계 발열선은 히터코일(2,3)들이 2 중 나선형으로 권선됨에 따라 도 4에 나타난 바와 같이 심실(1) 외주면에 골이 형성되고 나머지 공간에 내부절연체(4)가 채워지게 되어 히터코일(2,3) 간의 단락을 막을 수 있게 구성된다. 따라서, 종래 침구류용 무자계 발열선의 경우에는 히터코일 하나가 종방향으로 배치되고 그 위에 다른 히터코일이 권선되어 이들 두 히터코일 사이에 단락을 방지하기 위한 별도의 절연층이 필요하였지만, 본 발명에 따른 침구류용 무자계 발열선의 경우에는 히터코일(2,3) 간의 단락을 막기 위한 별도의 절연층이 불필요하다.In the magnetic field heating wire for bedding according to an embodiment of the present invention as described above, as the heater coils 2 and 3 are wound in a double spiral, valleys are formed on the outer circumferential surface of the ventricle 1 and the remaining spaces are shown in FIG. 4. The internal insulator 4 is filled to prevent a short circuit between the heater coils 2 and 3. Therefore, in the case of the conventional bedless heating wire for bedding, one heater coil is disposed in the longitudinal direction and another heater coil is wound thereon, so that a separate insulating layer is required to prevent a short circuit between the two heater coils. In the case of the non-magnetic heating wire for the bedding according to the need for a separate insulating layer to prevent a short circuit between the heater coil (2,3).

또한, 본 발명의 일 실시예에 따른 침구류용 무자계 발열선의 경우 히터코일(2,3)이 그 표면에 내열성, 내구성 및 절연효과가 뛰어난 에나멜층(2a,3a)의 코팅으로 IEEE 규격의 H 등급(대략 200℃ 이상) 이상을 유지할 수 있으므로 충분한 내열과 절연 특성을 가지게 되어 히터코일(2,3)의 내열과 절연을 위하여 피복되는 절연층의 두께를 대폭 줄일 수 있다.In addition, in the case of the magnetic field-free heating wire for bedding according to an embodiment of the present invention, the heater coils 2 and 3 are coated with enamel layers 2a and 3a having excellent heat resistance, durability, and insulation effect on the surface thereof. Since the grade (approximately 200 ° C. or more) can be maintained, it has sufficient heat resistance and insulation characteristics and can significantly reduce the thickness of the insulation layer coated for heat resistance and insulation of the heater coils 2 and 3.

이상에서 살펴본 바와 같이, 본 발명의 일 실시예에 따른 침구류용 무자계 발열선은 히터코일(2,3) 간 단락을 막기 위한 절연층이 필요치 않은데다 에나멜층(2a,3a) 코팅으로 히터코일(2,3)이 충분한 내열과 절연 특성을 가지면서 히터코일(2,3)의 내열과 절연을 위한 절연층의 두께가 대폭 줄게 되어, 그 굵기를 종래 침구류용 무자계 발열선의 1/2 이하로 줄일 수 있다.As described above, the magnetic field-free heating wire for bedding according to an embodiment of the present invention does not need an insulation layer to prevent a short circuit between the heater coils 2 and 3, and the heater coil 2 with the enamel layer 2a and 3a coating. (3) has sufficient heat resistance and insulation characteristics, and the thickness of the insulation layer for heat resistance and insulation of the heater coils (2, 3) is greatly reduced, and the thickness thereof is reduced to 1/2 or less of the non-magnetic heating wire for conventional bedding. Can be.

또한, 본 발명에 따른 침구류용 무자계 발열선의 경우 표면 전기장(충전 전하)를 제거하기 위한 금속쉴드(5)를 별도로 구성할 수 있게 되어, 본 발명의 일 실시예에 따른 침구류용 무자계 발열선에서는 전기장을 차폐하기 위한 금속쉴드(5)를 내부절연체(4) 위에 권선한 다음 그 위에 외부절연체(6)를 피복하여 구성하였다. 이에, 도 5에 도시된 바와 같이 금속쉴드는 내부절연체(4) 표면의 전기장(충전전하)를 접지(11)로 흘려 보냄으로써 전위를 0으로 유지하여 전기장에 의한 전자파를 차단할 수 있다. 이 금속쉴드(5)는 순수하게 접지(11)만을 위한 것으로 고전류가 흐르지 않고 전기장만을 접지(11)로 방전시켜 주므로 히터코일(2,3)의 2 배 이상의 권선 간격을 가지고도 충분히 방전할 수 있게 되어 생산성 증대 및 제조원가 절감을 가능하게 한다.In addition, in the case of the non-magnetic heating wire for bedding according to the present invention it is possible to separately configure the metal shield (5) for removing the surface electric field (charge charge), in the non-magnetic heating wire for bedding according to an embodiment of the present invention The metal shield 5 for shielding the electric field was wound on the inner insulator 4 and then covered with the outer insulator 6 thereon. Accordingly, as shown in FIG. 5, the metal shield may block an electromagnetic wave caused by the electric field by maintaining an electric potential at 0 by flowing an electric field (charge) on the surface of the internal insulator 4 to the ground 11. Since the metal shield 5 is purely for the ground 11 and does not flow high current and discharges only the electric field to the ground 11, the metal shield 5 can be sufficiently discharged even with a winding distance of twice or more than that of the heater coils 2 and 3. To increase productivity and reduce manufacturing costs.

도 6에 도시된 것은 본 발명의 다른 실시예에 따른 침구류용 무자계 발열선으로, 여기에서는 히터코일(2,3) 간 단락을 막기 위한 내부절연체와 금속쉴드가 배제되어 있다. 이 실시예에서와 같이, 본 발명에 따르면 히터코일(2,3)이 2 중 나선형으로 권선됨에 따라 히터코일(2,3) 간의 단락을 막기 위한 절연층이 불필요하게 되어 침구류용 무자계 발열선을 심선(1) 위에 하나의 절연층(외주절연체(6))만 피복하여 더욱 가늘게 구성할 수 있다.6 is a magnetic field heating wire for bedding according to another embodiment of the present invention, in which an internal insulator and a metal shield to prevent a short circuit between the heater coils 2 and 3 are excluded. As in this embodiment, according to the present invention, as the heater coils 2 and 3 are wound in a double spiral, an insulation layer for preventing a short circuit between the heater coils 2 and 3 becomes unnecessary, thereby providing a magnetic field-free heating wire for bedding. Only one insulating layer (the outer circumferential insulator 6) is coated on the core wire 1, whereby it can be configured to be thinner.

이상 살펴본 바와 같이 본 발명에 의한 침구류용 무자계 발열선에 따르면, 2 가닥의 히터코일이 2중 나선형으로 병렬 권선되어 히터코일 간의 단락방지를 위한 절연층이 필요치 않은데다 고가(高價)의 테프론, 유리섬유의 절연체를 사용하지 않으므로 침구류용 무자계 발열선의 생산성 향상 및 제조원가 절감을 도모할 수 있다. 또한, 그 굵기를 크게 줄일 수 있으므로 침구류에 적용하는 경우 인체에 배기는 것을 막을 수 있으며, 따라서 침구류용 무자계 발열선의 사용 범위를 보온층이 두꺼운 전기 매트는 물론이고 전기요나 전기장판과 같은 얇은 침구류까지 확대할 수 있다.As described above, according to the magnetic field-free heating wire for bedding according to the present invention, since two heater coils are wound in parallel in a double spiral, an insulation layer for preventing a short circuit between the heater coils is not necessary, and expensive Teflon and glass fibers are required. Since no insulator is used, productivity of the magnetic field-free heating wire for bedding can be improved and manufacturing cost can be reduced. In addition, since the thickness can be greatly reduced, when applied to bedding, it can be prevented from exhausting to the human body. Therefore, the range of use of the magnetic field-free heating wire for bedding is not only thin, such as electric mats and electric blankets, but also thick electric mats. Can extend to bedding.
