Description
본 고안은 전자기장(전기장과 자기장)이 차폐 및 상쇄되는 발열선을 이용한 전열매트 제어기에 관한 것이다.The present invention relates to a heat transfer mat controller using a heating wire that shields and cancels electromagnetic fields (electric and magnetic fields).
일반적으로 전하(電荷)는 공간에 전기장(電氣場)을 만들고, 이동하는 전하, 즉, 전류(電流)는 그 주위를 둘러싼 전기장을 만든다.In general, electric charges create an electric field in space, and moving charges, that is, electric currents, create an electric field surrounding it.
그리고, 도체에 전류가 흐르면 도체 주위에 자기장이 형성되고 상기 전류가 특정의 주파수를 가지는 경우 이에 상응하는 교번 전기 자기장이 형성된다. 이때, 전하(電荷)가 높을수록 전기장(電氣場)은 커지고 전류(電流)의 흐름이 많을수록 자기장(磁氣場)은 커지게 되는데, 주기적으로 세기가 변하는 자기장(전자파)과 전기장(전기파)이 공간을 통해 전파되는 것을 전자기파라고 한다.When a current flows through the conductor, a magnetic field is formed around the conductor, and when the current has a specific frequency, an alternating electric magnetic field is formed. At this time, the higher the charge, the larger the electric field, and the more the current flows, the larger the magnetic field. The magnetic field (electromagnetic wave) and electric field (electromagnetic wave) whose intensity changes periodically are Propagation through space is called electromagnetic waves.
따라서, 도체에 교류전류가 흐르면 전원주파수(50/60㎐)의 전자기파가 자연적으로 발생되며, 상기 전자기파는 인체의 많은 곳을 자극하여 피해를 입히게 된다. Therefore, when an alternating current flows through the conductor, electromagnetic waves of a power source frequency (50/60 Hz) are naturally generated, and the electromagnetic waves stimulate and damage many places of the human body.
위와 같은 전기장을 제거하는데 가장 효과적인 방법으로는 전기장 발생원(도체, 전열매트, 전열보온기, 각종 전기기기 등)을 전도체로 감싸 완전 차폐시킨 후 상기 전도체를 대지에 접속시켜 전도체로 유기되는 전기장이 대지로 방출되도록 하는 것이고, 자기장을 제거하는데 가장 효과적인 방법으로는 투자율이 높은 금속체로 상기 자기장 발생원을 완전히 감싸 차폐시킴으로써 자기장이 외부로 방출되는 것을 차단하는 것이다.The most effective way to remove the above electric field is to surround the electric field generating source (conductor, heat mat, heat insulation, various electric equipment, etc.) with a conductor and completely shield it, and then connect the conductor to the earth and the electric field induced by the conductor is grounded. The most effective way to remove the magnetic field is to completely shield the magnetic field source with a high permeability metal to shield the magnetic field from being released to the outside.
그리고, 전열매트와 같이 발열선이 넓은 면적에 걸쳐 분포하는 경우 전기장을 제거하기 위하여 전열매트 전체를 전도체로 완전히 감싸는 방법과 자기장을 제거하기 위하여 투자율이 높은 금속재로 전열매트 전체를 완전히 감싸는 방법이 있으나, 경제적인 측면에서 많은 비용이 들어가기 때문에 현실성이 없다.And, if the heating wire is distributed over a large area like the heating mat, there is a method of completely wrapping the entire heating mat with a conductor to remove the electric field, and a method of completely wrapping the whole heating mat with a high permeability metal to remove the magnetic field. It is not realistic because of the high cost in terms of economy.
한편, 본 고안자는 상기와 같은 문제점을 해소하기 위하여 권심 외주면에 감겨 온도센서의 작용을 하는 센서권선과, 상기 센서권선 외주면에 반대방향으로 왕복 권회되어 발열작용을 하는 발열권선과, 상기 발열권선 외주면에 권회되는 차폐권선과, 각 권선 사이의 절연을 유지하는 복수의 절연부재로 구성되어 발열권선으로부터 발생되는 전기장과 자기장을 효과적으로 차폐 및 상쇄시킬 수 있도록 한 "전기 자기장 차폐 및 상쇄 기능을 갖는 발열선"을 2003. 7. 16. 제10-2003-0048770호로 특허출원하여 2003. 8. 27. 특2003-0069924호로 공개된 바 있다.On the other hand, the present inventors, in order to solve the above problems, the sensor winding wound on the outer circumferential surface of the winding core to act as a temperature sensor, and the heating winding reciprocating in the opposite direction to the outer surface of the sensor winding to generate heat, and the heating winding outer peripheral surface A "heating wire having an electric magnetic field shielding and offset function" composed of a shielding winding wound around and a plurality of insulating members for maintaining insulation between each winding to effectively shield and offset the electric and magnetic fields generated from the heating winding. The patent application was issued on July 16, 2003, filed with No. 10-2003-0048770, and was published on August 27, 2003, special publication 2003-0069924.
상기 특허고안에 개시된 발열선은 도 1, 도 2에 도시한 바와 같이 소정 직경의 절연 권심(1) 외주면에 센서권선(S1)(S2)이 소정 간격으로 감긴(권회) 다음 권심(1) 양측으로 그 끝단이 돌출되고, 상기 권심(1) 외주면에 나이론 재질의 1차 절연부재(2)가 소정 직경으로 피복되고, 상기 1차 절연부재(2)의 외주면에 감기(권회) 리턴부(HC)를 갖는 발열권선(H1)(H2)이 반대방향으로 왕복 권회되고, 상기 1차 절연부재(2)의 외주면과 발열권선(H1)(H2) 외주면에 2차 절연부재(3)가 소정 직경으로 피복되고, 상기 2차 절연부재(2) 외주면에 차폐권선(C1)(C2)이 소정 간격으로 권회된 다음 2차 절연부재(2)의 양측으로 그 끝단이 돌출되고, 상기 2차 절연부재(3)와 차폐권선(C1)(C2) 외주면에 3차 절연부재(4)가 소정 직경으로 피복되어 발열선(HS)이 구성된다.As shown in Figs. 1 and 2, the heating wire disclosed in the patent draft is wound around the winding cores 1 (S2) at predetermined intervals on the outer circumferential surface of the insulation core 1 of a predetermined diameter (winding), and then to both sides of the winding core 1. An end thereof protrudes, the primary insulating member 2 of nylon is coated on the outer circumferential surface of the winding core 1 to a predetermined diameter, and wound (wound) return unit HC is wound on the outer circumferential surface of the primary insulating member 2. The heating winding H1 (H2) having a reciprocating winding in the opposite direction, the secondary insulating member (3) on the outer peripheral surface and the outer peripheral surface of the heating winding (H1) (H2) of the primary insulating member 2 to a predetermined diameter The shielding windings C1 and C2 are wound at predetermined intervals on the outer circumferential surface of the secondary insulating member 2, and then ends thereof protrude to both sides of the secondary insulating member 2, and the secondary insulating member ( 3) and the tertiary insulating member 4 are coated on the outer circumferential surface of the shielding windings C1 and C2 with a predetermined diameter to form the heating line HS.
상기 발열권선(H1)(H2)으로는 전열매트 제어기에 의해 단속되는 교류전원(AC 110V/AC 220V)이 공급되어 발열(發熱)되며, 상기 센서권선(S1)(S2)은 발열권선(H1)(H2)의 발열온도를 전류(또는 전압)로 검출하여 제어기의 온도비교부로 입력하게 되며, 차폐권선(C1)(C2)은 접지부에 연결되어 발열권선(H1)(H2)으로부터 발생되는 대부분(90% 이상)의 전기장과 자기장을 차폐 및 상쇄시키는 방법으로 제거하게된다.AC power (110V / AC 220V) intermittently supplied by the heat transfer mat controller is supplied to the heat generating windings H1 and H2 to generate heat, and the sensor windings S1 and S2 are heat generating windings H1. The heating temperature of H2 is detected as a current (or voltage) and input to the temperature comparison part of the controller. The shield windings C1 and C2 are connected to the ground and are generated from the heating windings H1 and H2. Most (more than 90%) of the electric and magnetic fields are shielded and canceled out.
그리고, 상기 발열권선(H1)(H2)은 1차 절연부재(2) 외주면에 반대방향으로 왕복 권회되므로 발열권선(H1)(H2)으로 흐르는 전류방향은 반대로 된다. 따라서, 발열권선(H1)(H2)으로부터 발생되는 자기장의 방향이 반대방향으로 되고 전류치는 동일하므로 발생되는 대부분의 자기장이 상쇄된다. 그리고 상기 권선(S1)(S2)(C1)(C2)들은 구리 또는 합금선과 같은 도전선이며, 발열권선(H1)(H2)은 발열선이다.Since the heating windings H1 and H2 are reciprocated in the opposite direction to the outer circumferential surface of the primary insulating member 2, the current direction flowing to the heating windings H1 and H2 is reversed. Therefore, since the direction of the magnetic field generated from the heating windings H1 and H2 is reversed and the current value is the same, most of the generated magnetic fields are canceled out. The windings S1, S2, C1, and C2 are conductive wires such as copper or alloy wires, and the heating windings H1 and H2 are heating wires.

본 고안에 사용되는 발열선(HS)은 앞서 기술한 바와 같이 소정 직경의 절연 권심(1) 외주면에 센서권선(S1)(S2)이 소정 간격으로 감긴(권회) 다음 권심(1) 양측으로 그 끝단이 각각 돌출되고, 상기 권심(1) 외주면에 나이론 재질의 1차 절연부재(2)가 소정 직경으로 피복되고, 상기 1차 절연부재(2)의 외주면에 감기 리턴부(HC)를 갖는 발열권선(H1)(H2)이 서로 접하지 않도록 반대방향으로 왕복 권회되고, 상기 1차 절연부재(2)의 외주면과 발열권선(H1)(H2) 외주면에 2차 절연부재(3)가 소정 직경으로 피복되고, 상기 2차 절연부재(2) 외주면에 차폐권선(C1)(C2)이 소정 간격으로 권회된 다음 2차 절연부재(2)의 양측으로 끝단이 각각 돌출되고, 상기 2차 절연부재(3)와 차폐권선(C1)(C2) 외주면에 3차 절연부재(4)가 소정 직경으로 피복되어 와이어 형태의 발열선(HS)이 구성된다.Heat wire (HS) used in the present invention, as described above, the sensor winding (S1) (S2) is wound on the outer peripheral surface of the insulation core (1) of a predetermined diameter at a predetermined interval (winding), and then both ends of the core (1) Are respectively protruded, the primary winding member 2 of nylon material is coated on the outer circumferential surface of the winding core 1 to a predetermined diameter, and a heating winding having a winding return portion HC on the outer circumferential surface of the primary insulating member 2. (H1) and (H2) are reciprocated in the opposite direction so as not to contact each other, and the secondary insulating member (3) has a predetermined diameter on the outer circumferential surface of the primary insulating member (2) and the outer circumferential surface of the heating winding (H1) (H2). The shielding windings C1 and C2 are wound at predetermined intervals on the outer circumferential surface of the secondary insulating member 2, and ends thereof protrude to both sides of the secondary insulating member 2, respectively. 3) and the tertiary insulating member 4 are coated on the outer circumferential surface of the shielding windings C1 and C2 with a predetermined diameter to form a heating wire HS in the form of a wire.
그리고, 상기 발열권선(H1)(H2)으로는 제어기에 의해 단속되는 교류전원(AC 110V/AC 220V)이 공급되어 발열(發熱)되며, 상기 센서권선(S1)(S2)은 발열권선(H1)(H2)의 발열온도를 전류(또는 전압)로 검출하여 제어기의 온도비교부로 입력하게 되며, 차폐권선(C1)(C2)은 접지선별회로부(G)의 그라운드 단자(GROUND)를 통하여 대지 또는 교류전원 단자에 접지되게 구성된다.The AC windings AC 110V / AC 220V supplied by the controller are supplied to the heating windings H1 and H2 to generate heat, and the sensor windings S1 and S2 are heating windings H1. H2 is detected as a current (or voltage) and input to the temperature comparison unit of the controller. The shield windings C1 and C2 are connected to the ground or ground through the ground terminal GROUND of the ground selection circuit unit G. It is configured to be grounded to the AC power supply terminal.

Most of the magnetic field generated from H2) is canceled, and shielded windings C1 and C2 positioned outside the heating line HS are connected to the ground terminal GROUND or one side AC power terminal of the ground selection circuit unit G. Since it is connected to the ground, most of the electric field generated from the heating windings H1 and H2 is shielded.
따라서, 발열권선(H1)(H2)으로부터 발생되는 전기장과 자기장의 대부분(90% 이상)이 차폐 및 상쇄되면서 인체에 해로운 유해전자파가 제거되며, 종래처럼 전열매트를 제조할 때 필요로하던 전열매트와 거의 같은 평면적의 차폐부재가 불필요해진다.Therefore, most of the electric and magnetic fields (more than 90%) generated from the heating coils H1 and H2 are shielded and canceled to remove harmful electromagnetic waves harmful to the human body.

상기 센서권선은 발열권선의 발열온도에 비례하거나 반비례하는 전기저항 변화에 의한 온도값(전압 및/또는 전류)로 감지하여 온도비교부(C)로 입력하게된다. 상기 저항변화 방식을 이용하는 경우 풀업저항을 통하여 센서권선으로 전원이 공급되며, 발열온도에 비례하여 센서권선의 저항값이 상승하면 풀업저항을 통하여 공급되는 전류가 변화하고, 따라서 온도가 감지된다. The sensor winding is sensed as a temperature value (voltage and / or current) due to a change in electrical resistance that is proportional to or inversely proportional to the heating temperature of the heating winding, and is input to the temperature comparing unit C. In the case of using the resistance change method, power is supplied to the sensor winding through the pullup resistor. When the resistance value of the sensor winding increases in proportion to the heating temperature, the current supplied through the pullup resistor changes, and thus the temperature is sensed.
도 4는 본 고안 일 실시예로 도시한 회로도로, 교류전원 양단자(AC1)(AC2)에 휴즈(SF)와, 온도휴즈(TF)와, 전원스위치(SW)와, 발열선(HS)의 히터권선(H1)(H2)과, 트라이악(TRAIC) 등의 스위칭소자(TH)가 직렬로 접속된다.4 is a circuit diagram illustrating an embodiment of the present invention, wherein the fuse SF, the temperature fuse TF, the power switch SW, and the heating line HS are connected to both terminals AC1 and AC2 of the AC power source. The heater windings H1 and H2 and a switching element TH such as a triac TRAIC are connected in series.
또한 교류전원 양단자(AC1)(AC2)에 저항(R1), 캐패시터(C6), 다이오드(D1)(D2), 캐패시터(C7), 제너 다이오드(ZD)로 구성되는 직류전원부가 접속되어 각 회로 동작에 필요한 직류 정전압(+Vcc)이 공급된다.In addition, a DC power supply unit consisting of a resistor R1, a capacitor C6, a diode D1 (D2), a capacitor C7, and a Zener diode ZD is connected to both terminals AC1 and AC2. DC constant voltage (+ Vcc) required for operation is supplied.
또한 교류전원 양단자(AC1)(AC2)에 접지단자(GROUND)가 접속된 접지선별회로부(G)가 접속된다. 상기 접지선별회로부(G)는 교류전원 단자(AC1) 또는 다른 교류전원 단자(AC2) 또는 접지단자(GROUND) 중 하나를 선택해 발열선(HS)의 차폐권선(C1)(C2)에 접속시켜 접지회로를 구성함으로써 발열권선(H1)(H2)으로부터 발생되는 전기장(유해전자파)이 흡수 제거된다.In addition, a ground selection circuit portion G having a ground terminal GROUND connected to both terminals AC1 and AC2 is connected. The ground selection circuit unit G selects one of an AC power terminal AC1, another AC power terminal AC2, or a ground terminal GROUND, and connects the shielding winding C1 (C2) of the heating line HS to a ground circuit. By so doing, the electric field (harmful electromagnetic waves) generated from the heating windings H1 and H2 is absorbed and removed.
상기 접지선별회로부(G)와 발열선(HS)의 차폐권선(C1)(C2) 사이에는 보호소자인 폴리 스위치(PS)가 접속되어 고장이나 접지 선택의 잘못으로 접지선별회로부(G)와 차폐권선(C1)(C2) 사이에 110V/220V의 교류전원이 인가되는 경우 상기 폴리 스위치(PS)에 의해 발열선(HS)이 보호된다.A poly switch PS as a protection element is connected between the ground selection circuit unit G and the shield windings C1 and C2 of the heating line HS, so that the ground selection circuit unit G and the shielding winding ( When AC power of 110V / 220V is applied between C1) and C2, the heating line HS is protected by the poly switch PS.
상기 폴리 스위치(Poly Switch)는 회로에 과전류가 유입되면 이 전류에 의해 발생하는 주울(Joule)열에 의하여 폴리 스위치(PS)가 저(低) 저항체에서 고(高) 저항체로 변하면서 과전류가 제한되고 발열선(HS)이 보호되며, 반대로 과전류 요인이 제거되고 소자의 온도가 낮아지면 저항값은 다시 초기상태의 낮은 값으로 복귀하여 회로의 정상동작이 가능해지는 자기 복구형 스위치이다.In the poly switch, when an overcurrent flows into the circuit, the overcurrent is limited as the poly switch PS changes from a low resistor to a high resistor by Joule heat generated by the current. On the contrary, if the heating line HS is protected and the overcurrent factor is removed and the temperature of the device is lowered, the resistance value is returned to the low value of the initial state so that the circuit can be normally operated.

본 고안에서 접지선별회로부(G)는 수동 또는 자동 셀렉터 방식으로 회로 결선이 선택되며, 그 등가회로는 도 6에 일 예로 도시한 것처럼 폴리 스위치(PS)에 접속된 가동단자와 교류전원선(AC1)(AC2)과 접지단자(GROUND)에 각각 접속되는 고정단자로 구성된다.In the present invention, the ground selection circuit unit (G) is a circuit connection is selected by a manual or automatic selector method, the equivalent circuit is a movable terminal and an AC power supply line (AC1) connected to the poly switch PS as shown in FIG. It consists of a fixed terminal connected respectively to (AC2) and a ground terminal (GROUND).
도 5는 본 고안 다른 실시예의 회로도로, 센서권선(S1)(S2)이 발열온도에 비례하는 전압으로 감지하는 도 4와는 달리 발열온도에 비례한 저항변화를 이용하여 센서권선(S1)(S2)이 온도를 감지하게 된다.5 is a circuit diagram of another embodiment of the present invention, unlike the sensor winding (S1) (S2) is detected as a voltage proportional to the heating temperature by using a resistance change proportional to the heating temperature sensor winding (S1) (S2) ) Will sense the temperature.
즉, 일측 센서권선(S2)에 저항(R7)과 교류 전원단자(AC1)를 직렬로 접속하고, 타측 센서권선(S1)에 저항(R2)과 전원단자(AC2)를 직렬로 접속하여 센서권선(S1)(S2)으로 교류전원이 공급되게 구성한 것으로, 발열선(H1)(H2)의 발열온도에 비례하여 센서권선(S1)(S2)의 내부저항이 상승하게되면 저항(R7)을 통해 상기 센서권선(S1)(S2)으로 공급되는 전류가 변하게 되므로 온도에 비례하는 온도전류 및 그 온도전압을 얻을 수 있게된다.That is, the resistor R7 and the AC power supply terminal AC1 are connected in series to one sensor winding S2, and the resistor R2 and the power supply terminal AC2 are connected in series to the other sensor winding S1 and the sensor winding is connected in series. AC power is supplied to S1 and S2. When the internal resistance of the sensor windings S1 and S2 increases in proportion to the heating temperature of the heating lines H1 and H2, the resistance R7 is applied to the power supply. Since the current supplied to the sensor windings S1 and S2 changes, a temperature current proportional to the temperature and its temperature voltage can be obtained.
따라서, 발열권선(H1)(H2)의 발열온도에 따라 변화하는 센서권선(S1)(S2)의 도체 전기저항을 검출하여 온도를 제어할 수 있도록 한 것이다.Therefore, it is possible to control the temperature by detecting the conductor electrical resistance of the sensor windings S1 and S2 that change according to the heating temperature of the heating windings H1 and H2.
상기 도 5에 의한 센서권선(C1)(C2)의 경우, 발열온도에 준하여 저항변화가 심한 도체가 바람직하며, 1차 절연부재(2)는 나일론 대신 내열성과 절연저항이 보다 우수한 실리콘으로 구성할 수 있다.In the case of the sensor windings C1 and C2 of FIG. 5, a conductor with a high resistance change is preferable according to the heating temperature, and the primary insulation member 2 may be made of silicon having better heat resistance and insulation resistance instead of nylon. Can be.
그리고, 상기 온도전압은 다이오드(D4)에 의해 정류된 다음 온도비교부(C)로 입력되어 기준온도값과 비교되며, 온도비교값이 설정범위를 벗어나는 경우, 즉, 비교 판단된 온도가 설정온도보다 초과 상승하는 경우 오프신호(LOW 액티브)를 출력하여 트리거부(T)가 스위칭 소자(TH)를 오프(off)하게되고 발열권선(H1)(H2)의 발열이 중단되므로 온도가 하강하게되며, 온도하강에 따른 온도감지값은 온도비교부(C)로 계속 입력되어 설정된 기준온도값과 비교 판단된다.Then, the temperature voltage is rectified by the diode (D4) and then input to the temperature comparison unit (C) and compared with the reference temperature value, when the temperature comparison value is out of the set range, that is, the temperature is determined to compare the set temperature If the temperature rises further, the trigger signal T is turned off by outputting an off signal (LOW active) and the heat generation of the heating windings H1 and H2 is stopped. The temperature detection value according to the temperature drop is continuously inputted to the temperature comparison unit C to be compared with the set reference temperature value.
반대로, 비교 판단된 온도가 설정온도 미만으로 하강하는 경우 온신호(HIGH 액티브)를 출력하여 트리거부(T)가 스위칭 소자(TH)를 턴 온(turn on)하게되고 발열권선(H1)(H2)의 발열이 재개되므로 온도가 상승하게되며, 온도 상승에 따른 온도감지값은 온도비교부(C)로 계속 입력되어 설정된 기준온도값과 비교판단되며, 이러한 과정으로 발열온도가 설정된 온도범위로 발열된다.On the contrary, when the temperature judged to fall below the set temperature, the trigger unit T turns on the switching element TH by outputting an ON signal HIGH active and generating heat windings H1 and H2. As the heating of) resumes, the temperature rises, and the temperature detection value according to the temperature rise is continuously inputted to the temperature comparing unit (C) and compared with the set reference temperature value. In this process, the heating temperature is generated in the set temperature range. do.
또한 본 고안 도 5의 경우, 일측 센서권선(S2)이 저항(R4)을 통하여 교류전원(AC)에 연결되어 있으므로 발열권선(H1)(H2)의 발열온도에 따라 센서권선(S1)(S2)의 저항이 변화하면서 온도비교부(C)로 입력되는 입력온도값도 변화되며, 상기 입력온도값은 온도비교부(C)에서 기준온도값과 비교 판단되고, 상기 온도비교부(C)의 제어신호에 따라 발열권선(H1)(H2)의 발열온도가 설정온도로 제어된다.In addition, in the case of the present invention Figure 5, since one side of the sensor winding (S2) is connected to the AC power source (AC) through the resistor (R4) according to the heating temperature of the heating winding (H1) (H2) sensor winding (S1) (S2) As the resistance of) changes, the input temperature value input to the temperature comparator C is also changed, and the input temperature value is compared with the reference temperature value in the temperature comparator C, and the temperature of the temperature comparator C The heating temperature of the heating windings H1 and H2 is controlled to the set temperature according to the control signal.
또한 센서권선(S1)(S2)에 접속된 풀다운 저항(R2)은 온도휴즈(TF)에 물리적으로 접촉하여 있다가 발열권선(H1)(H2)의 과도한 발열에 의해 1차 절연부재(1)가 융해되면서 발열권선(H1)(H2)과 센서권선(S1)(S2)이 단락(Short)되는 경우 상기 저항(R2)이 과도하게 가열되며, 따라서, 상기 저항(R2)에 접하여 있는 온도휴즈(TF)로 과도한 열이 곧바로 전달되어 온도휴즈(TF)가 융단되므로 회로로 공급되던 교류전원이 차단되면서 회로가 보호되고, 전열매트의 손상 및 화재등이 방지된다.In addition, the pull-down resistor R2 connected to the sensor windings S1 and S2 is in physical contact with the temperature fuse TF, and the primary insulating member 1 is caused by excessive heat generation of the heating windings H1 and H2. When the heating coils H1 and H2 and the sensor windings S1 and S2 are shorted as they are melted, the resistor R2 is excessively heated, and thus, a temperature fuse in contact with the resistor R2. Excessive heat is immediately transferred to (TF) and the temperature fuse (TF) is fused, so that the AC power supplied to the circuit is cut off, thereby protecting the circuit and preventing damage to the heat transfer mat and fire.
본 고안에서 발열권선(H1)(H2)은 교류전원(AC 110V/220V)으로 동작하므로 상기 스위칭 소자(TH)는 트라이악(TRAIC) 등의 양파(兩波) 스위칭소자가 바람직하다. In the present invention, since the heating winding H1 and H2 operate as an AC power source 110V / 220V, the switching element TH is preferably an onion switching element such as a triac TRAIC.

It has the effect of being.
