본 고안은 수직교류왜형파를 이용한 발열체에 관한 것으로 더욱 상세히 설명하면, 전기기기 사용중에 발생되는 인체에 유해한 전자파를 최소한으로 억제함은 물론 교류 저전압(AC 1V∼15V)를 공급하더라도 높은 발열효과를 얻을 수 있도록 하며, 발열체의 수명을 연장토록하는 것이다. 이와 같은 본 고안은 전기장판, 전기담요, 전기찜질기, 전기방석등 전기침구류에 이용 가능하다.The present invention relates to a heating element using a vertical alternating distortion wave, and in more detail, it minimizes harmful electromagnetic waves generated during the use of electrical equipment and provides a high heating effect even when AC low voltage (AC 1V to 15V) is supplied. To extend the life of the heating element. This invention can be used for electric bedding, such as electric blanket, electric blanket, electric steamer, electric cushion.
일반적으로 발열체 니크롬선(열선)과 같은 저항에 큰 도선에 전류를 흘려 그때에 발생하는 주울열을 이용하는 것으로 발열온도 조절을 전압에 의하여 가변 조절하는 것이 아니라 온도 감지센서가 설정 온도 이상이 되면 회로에 공급되는 높은 전원 전압(AC 100V∼240V)을 차단하는 방식을 채용하고 있기 때문에 높은 전원 전압사용에 수반하여 인체에 유해한 전자파의 전기장강도도 그만큼 높아지게 된다.In general, Joule heat generated at that time is caused by flowing current through a large conductor with resistance such as heating element nichrome wire (heating wire). It is not used to change the heating temperature control by voltage, but when the temperature sensor is above the set temperature, Since the method of blocking the high power supply voltage (AC 100V-240V) supplied is adopted, the electric field strength of electromagnetic waves harmful to the human body increases with the use of high power supply voltage.
주지하는 바와 같이 전기기기 중에서도 인체의 피부와 접촉하여 사용되는 전기담요, 전기장판 또는 전기찜질기, 전기방석등 전기침구류에서 발생되는 전기장 강도가 250V/m로서 매우 높은 편이고, 이와 같이 유해 전자파가 다량 방출되는 제품을 장시간 사용하게 되면 두통, 심장이상 초래, 근육통 또는 암에 걸릴 확률이 높아진 사이에 공급하는 이유는 제3b도와 같이 AC 10V 전압을 일예로서 설명할 때 제3a도에 도시한 일반적인 교류 정현파의 최대치보다 수직 교류 왜형파의 최대치가 높고 1주기를 기준으로 할 때 순간적으로 +,-최대치가 상승하여 OV전위에서 충, 방전을 행하기 때문에 빠른, 충, 방전에 의하여 많은 전자의 부딪침으로 높은 열을 발생하기 때문이다.As is well known, the electric field intensity generated from electric bedding such as electric blankets, electric sheets or electric steamers, and electric cushions used in contact with the human skin is very high as 250 V / m. Prolonged use of the product during a long period of headache, heart failure, muscle pain or cancer increases the reason for supplying the AC 10V voltage as shown in FIG. 3B as an example. When the maximum value of vertical AC distortion wave is higher than the maximum value and the one-period reference, the + and-maximum values are instantaneously increased to perform charging and discharging at the OV potential. Because it generates heat.
만일 제3a도에 도시된 정현파를 갖는 교류 전압을 본 고안의 발열체(H)에 공급하게 되면 최대치까지 사이 곡선을 그리며, 상승, 하강하게 되고 OV전위에서는 충, 방전이 거의 이루어지지 않기 때문에 수직 교류왜형파를 갖는 교류 전압 인가시보다 약3배 전도의 높은 전압을 필요로 하므로 그만큼 유해 전자파가 많이 발생되는 문제점이 있으므로 바람직하지 못하다.If the AC voltage having the sinusoidal wave shown in FIG. 3a is supplied to the heating element H of the present invention, a curve is drawn up to the maximum value and rises and falls, and since the charging and discharging are rarely performed at the OV potential, the vertical AC Since a high voltage of about three times conduction is required than when an alternating voltage having a distortion wave is applied, it is not preferable because there is a problem that many harmful electromagnetic waves are generated.
제4a도에서 본 고안의 발열체(H)를 높은 열은 요하지 않지만 넓은 면적을 필요로하는 전기장판 또는 전기담요(20)에 적용한 1실시예의 사용 상태도를 나타낸것으로서, 이 경우에는 알루미늄박판의 폭(W1)을 좁게 하고 ㄹ자 형상으로 연속하여 배설할 수가 있다.FIG. 4a shows a state diagram of an embodiment in which the heating element H of the present invention is applied to an electric blanket or an electric blanket 20 which does not require high heat but needs a large area. In this case, the width of the aluminum sheet ( W1) can be narrowed and excreted continuously in a r-shape.
제4b도에는 본 고안의 발열체(H)를 넓은 면적은 요하지 않지만 높은 열을 필요로 하는 전기방석 또는 전기찜질기, 물침대 히터(21)에 적용한 다른 실시예의 사용상태도를 나타낸 것으로서, 이 경우에는 알루미늄 박판의 폭(W1)을 넓게 하고 -자 형상으로 다수개를 세로로 배설할 수가 있다.Figure 4b is a diagram showing the state of use of another embodiment applied to the electric heating element (H) of the present invention does not require a large area but requires a high heat electric cushion or electric steamer, water bed heater 21, in this case, aluminum sheet It is possible to widen the width (W1) of and to arrange a plurality of vertically in the shape of-.
본 고안의 발열체는 물론 상기 두 경우에만 한정되는 것이 아니고 사용 제품의 목적에 따라 발열체(H)의 넓이와 길이는 임의로 선택할 수가 있는 것이다.The heating element of the present invention is, of course, not limited to the above two cases, and the width and length of the heating element H can be arbitrarily selected according to the purpose of the product to be used.
이상에서와 같이 본 고안에 의한 발열체는 수직 교류 왜형파를 갖는 교류 저전압(AC 1V∼15V)을 공급받아 단시간에 높은 발열효과를 제공할 수가 있음을 물론 저전압 교류를 사용하므로써 인체에 유해한 전자파 발생을 최대한 억제할 수가 있는 것이어서 특히 인체의 피부와 접촉하여 사용되는 전기 침구류에 활용가치가 높은 실용적인 고안인 것이다.As described above, the heating element according to the present invention can provide high heating effect in a short time by receiving AC low voltage (AC 1V ~ 15V) having vertical AC distortion wave, and of course, it is possible to generate harmful electromagnetic waves by using low voltage AC. Since it can be suppressed as much as possible, it is a practical design with high utility value, especially for electric bedding used in contact with the human skin.
