본 고안은 전류의 흐름에 의해 열을 발생하여 인체와 직접 접촉시켜 인체를 난방하는 접촉 채난(採煖)기에 관한 것이다. 자세히 설명해보면 2줄의 발열선을 밀착시켜 단일가열체로 형성하여, 이에 가열을 위한 전류를 왕복으로 흐르게 하면 자속이 상쇄되어 무자계가 실현되며, 이렇게 만들어진 가열체는 인체에 밀착시켜 채난하더라도 인체에 해를 끼치지 않는 무자계 채난기가 된다.The present invention relates to a contact channel heater that generates heat by the flow of electric current and directly contacts the human body to heat the human body. To explain in detail, two lines of heating wires are in close contact with each other to form a single heating element, and when a current for heating flows in a reciprocating manner, the magnetic flux is canceled to realize a non-magnetic field. It becomes a magnetless chafing season.
일반적으로 접촉 전열 채난기는 전열선에 교류 전류를 공급하여 발열되게 하는 것으로 초기의 접촉 채난기는 첨부도면 제1도에 도시한 바와 같이, 접촉 채난기의 본체(1)에 발열선(2)을 1열로하여 지그재그로 일정간격을 유지하면서 배열하고, 발열선(2)의 양단부에는 교류전원이 인가되게 구성되어 있다.In general, the contact heat exchanger generates heat by supplying an alternating current to the heating wire. The initial contact air heater has a heating line 2 in a row in the main body 1 of the contact channel as shown in FIG. It arranges in a zigzag and maintains a constant space | interval, and is comprised so that AC power may be applied to the both ends of the heating line 2. As shown in FIG.
이와 같이 구성된 초기의 접촉 채난기는 발열선(2)의 양단부에 교류전원이 인가됨에 따라 발열되면서 인체를 가열하는 것으로서, 이 경우 발열선(2)에 공급되는 교류전류에 의하여 발열선(2)에 교번자계가 발생한다.The initial contact channel configured as described above heats the human body while being heated as AC power is applied to both ends of the heating wire 2, and in this case, the alternating magnetic field is applied to the heating wire 2 by the AC current supplied to the heating wire 2. Occurs.
이 교번자계는 인체에 유해한 것으로 사용자의 건강을 해치게 되므로 전열 접촉 채난기의 사용을 기피하게 되는 하나의 요인이 되고 있다.This alternating magnetic field is harmful to the human body and damages the user's health, which is one factor that avoids the use of the electrothermal contact channel.
근래에 와서 상기와 같은 문제점을 해결하기 위한 노력이 경주되기 시작, 첨부도면 제2도에 도시한 바와같이 균등발열선의 간격을 유지하면서 내외 2루프(loop)로 나누어 그의 전류 방향이 반대가 되게 함으로써 자계가 상쇄되게 하는 고안이 미국 특허(4908497)에 공시된 바 있다. 그러나 이 고안은 발열선 간격이 너무 넓어 누설자속이 많아 완전 무자계를 실현시키기가 곤란할 뿐 아니라 발열선의 평행, 등간격, 루프의 교대배열과 같은 제한 조건 때문에 적용되는 대상품에 따라서는 제작에 난점이 있을 수도 있다.In recent years, efforts to solve the above problems have begun to be raced, by dividing the inner and outer loops into two loops while maintaining an even heating line interval as shown in FIG. A devise to offset the magnetic field has been disclosed in US patent (4908497). However, this design is not only difficult to realize the complete magnetic field because the heating wire spacing is too wide and the leakage flux is high, and it is difficult to manufacture depending on the large products that are applied due to the constraints such as parallel, equal spacing, and alternating arrangement of the heating wires. There may be.
이에 반해 본 고안은 상기와 같은 문제점을 해결하기 위한 것으로서, 첨부도면 제3도와 같이 2열의 발열선이 상호 밀착되게 해서 단일발열체로 형성하여 일측단부의발열선을 상호간에 연결하고 이를 접촉 채난기의 본체에 지그재그로 배열하고 타측단부의 양단자에 교류전원이 인가되게 하여 교류전류가 흐름으로써 발열선에서 발생되는 교번자계가 상쇄되도록 하는 무자계 접촉 채난기를 제공하는데 그 목적이 있다. 이를 제3도에 상세히 설명한다.On the contrary, the present invention is to solve the problems as described above. As shown in the accompanying drawings, as shown in FIG. It is an object of the present invention to provide a magnetic contactless chaser which is arranged in a zigzag and allows AC power to be applied to both terminals of the other end so that an alternating magnetic field generated in a heating wire is canceled by the flow of AC current. This will be described in detail with reference to FIG. 3.
제3도는 본 고안의 무자계 접촉 채난기의 발열선 배열상태를 보인 도면으로써 접촉 채난기 본체(11)의 두발열선(1,2)간의 전기적 절연 간격은 유지하되 자기적 결합도가 높아 누설자속이 극소화되도록 밀착, 단일 가열체(3)로 형성하여 가열본체(11)에 배열 설치하고, 발열선(1,2)의 일측단부는 상호간에 연결시키고, 발열선(1,2)의 타측단부의 양단자(A,B)에는 제어부(도면에 도시되지 않았음)의 제어에 따라 교류전원이 인가되게 구성하였다.3 is a diagram showing the heating line arrangement of the magnetic fieldless contact channel of the present invention, while maintaining the electrical insulation interval between the two heating lines (1, 2) of the main body of the contact channel 11, the magnetic flux is high and the leakage flux is high. Formed in close contact with each other and minimized to form a single heating body (3), arranged on the heating body (11), one end of the heating line (1, 2) is connected to each other, both terminals of the other end of the heating line (1, 2) (A, B) was configured such that AC power was applied under the control of a controller (not shown).
이와 같이 구성된 본 고안의 채난기는 제어부의 제어에 따라 발열선(1,2)의 타측단부의 양단자(A,B)에 교류전원이 인가되면, 전류가 흘러 발열선(1,2)이 발열된다.According to the control device of the present invention configured as described above, when AC power is applied to both terminals A and B of the other end of the heating lines 1 and 2 under the control of the control unit, current flows to generate the heating lines 1 and 2.
이때 2열의 발열선(1,2)은 전기한 바와 같이 누설자속이 될 수 있는 대로 생기지 않도록 상호 밀착되어 있기 때문에 이에 서로 반대방향으로 교류전류가 흐를때 발생되는 교번자계가 상쇄되어 인체에 영향을 주지 않게 된다.At this time, since the two rows of heating wires (1, 2) are in close contact with each other so as to prevent leakage magnetic flux as described above, the alternating magnetic fields generated when AC current flows in opposite directions cancel each other out, thereby affecting the human body. Will not.
이상에서 상세히 설명한 바와 같이 본 고안은 발열선을 2열로 밀착시켜 단일 가열체로 형성하여 이에 왕복전류가 서로 반대방향으로 흐르게 함으로써 발열선에서 발생되는 교번자계가 상호간에 반대방향으로 되어 상쇄되는데 이경우 발열선(1,2)의 밀착도를 높여 교번자속이 누설되지 않도록 한다.As described in detail above, the present invention forms a single heating body by closely contacting the heating wires in two rows, and the reciprocating currents flow in opposite directions to each other, so that the alternating magnetic fields generated in the heating wires are offset in the opposite directions. Increase the adhesion of 2) to prevent leakage of the alternating flux.
실질적으로는 2발열선의 자기결합도를 높이기 위해 밀착도를 높이더라도 약간의 누설자속은 있을 것이나, 2발열선간의 절연물을 통과하지 못해 피가열체(주로 인체)에는 도달할 수 없을 것이므로 '무자계'라 한 것이며, '접촉'이라 한 이유는 열의 복사과정을 거치지 않고 전도에 의해 채난이 된다는 뜻이며, 이런 뜻에서 본 고안에 의한 전열기을 '무자계 접촉 채난기'라 한 것이다.In practice, even if the degree of adhesion is increased to increase the magnetic coupling of the second heating wire, there will be a little leakage flux, but because it cannot pass through the insulation between the two heating wires, it will not reach the heating element (mainly the human body). The reason for the contact is that the heating is carried out by conduction without going through the heat radiation process. In this sense, the electric heater according to the present invention is called the 'magnetic fieldless contacting machine'.
본 고안에 제시된 가열체는 2발열선을 밀착시켜 단일 가열체로 형성한 것이기 때문에 자속이 단일 가열체 외부로 누출될 수 없어 3차원 공간일지라도 가열체 배열에 관계없이 전 공간이 무자계가 되기 때문에 인체 접촉 채난기로 쓰이는 전기 요, 전기 이불, 전기 담요등에 적합하다. 이에 반해 제2도에 도시한 2루프 등간격배열 소자를 적용한 가열체는 건물과 가옥의 바닥, 벽체, 천정 등에 적합하며 인체에 대해서는 물침대용 물매트 가열용 평판 가열체에나 사용할 수 있을 것으로 생각된다.Since the heating element proposed in the present invention is formed as a single heating element by closely adhering two heating wires, the magnetic flux cannot leak out of the single heating element, so even though the space is three-dimensional, the entire space becomes magnetic regardless of the arrangement of the heating elements. It is suitable for electric blankets, blankets and blankets. On the other hand, the heating element to which the two-loop equally spaced array element shown in FIG. 2 is applied is suitable for the floors, walls, and ceilings of buildings and houses. .
