본 고안은 가스보일러등 가스기기의 파이롯트 버어너 순간점화장치에 관한 것으로, 특히 가스기기의 메인 전원을 이용하여 원텃치로 파이롯트 버어너를 순간점화시킬 수 있도록 한 것이다.The present invention relates to a pilot burner instant ignition device for a gas appliance such as a gas boiler, and in particular, it is possible to instantaneously ignite the pilot burner using a main power source of the gas appliance.

종래에는 제1a도에 도시된 바와같이 MPU(Magnetic Power Unit)(4)가 열전대(TC)의 기전력으로 작동되어 가스통로를 차단하도록 되어있어 파이롯트 버어너를 초기 점화하기 위하여는 열전대(TC)에 MPU(4)를 작동시킬 수 있는 기전력이 발생할 때까지 일정시간(약 10초 정도)동안 사용자가 밸브놉(5)을 누르고 있어야 하는 불편함이 있었다.Conventionally, as shown in FIG. 1A, the magnetic power unit (MPU) 4 is operated by the electromotive force of the thermocouple TC to block the gas passage, so that the initial stage of the pilot burner is ignited with the thermocouple TC. There was an inconvenience that the user must press the valve knob 5 for a predetermined time (about 10 seconds) until an electromotive force capable of operating the MPU 4 occurs.

또, 이와 유사한 장치로 제1b도와 같이 MPU(4)와 열전대(TC)에 건전지(BT)와 콘덴서(C) 그리고 마이크로 스위치(MS)를 직병렬 접속하여 밸브놉(5) 작동시 마이크로 스위치(MS)의 메인 접점(a)을 접점(c)에 접속시키면 콘덴서(C)가 일정시간 방전하여 파이롯트 버어너를 점화시키고, 열전대(TC)가 가열되어 MPU(4)를 작동시킬 수 있는 충분한 시간이 경과된 후에는 마이크로 스위치(MS)의 메인 접점(a)이 다시 접점(b)에 접속하여 콘덴서(C)가 건전지(BT)에 의해 재충전되도록 한 장치가 알려져 있으나, 이와같은 장치는 파이롯트 버어너를 점화시키기 위해 별도의 건전지(BT)를 사용하므로 건전지(BT)가 소모되었을 경우에는 제기능을 발휘하지 못하였으며, 연속방전식 점화가 가능한 가스보일러용 가스밸브에는 이를 적용시킬 수 없는 결점이 있었다.In a similar device, a battery BT, a capacitor C, and a micro switch MS are connected in parallel and parallel to the MPU 4 and the thermocouple TC as shown in FIG. 1B. When the main contact (a) of MS) is connected to the contact (c), the capacitor (C) discharges for a certain time to ignite the pilot burner, and the thermocouple (TC) is heated to operate the MPU (4) sufficient time. After this elapses, a device is known in which the main contact (a) of the micro switch (MS) is connected to the contact (b) again so that the capacitor (C) is recharged by the battery (BT). Since a separate battery (BT) is used to ignite the honor, it did not function properly when the battery (BT) was exhausted, and a defect that cannot be applied to a gas valve for a gas boiler capable of continuous discharge ignition is possible. there was.

본 고안은 이와같은 종래의 결점을 감안하여 안출한 것으로 별도의 건전지를 사용하지 않고 가스기기의 메인전원을 정류하여 파이롯트 버어너를 초기에 순간점화시킬 수 있도록 한 것인바, 이를 첨부된 도면 제2도와 제3도에 의하여 상세히 설명하면 다음과 같다.The present invention has been made in view of the above-mentioned drawbacks of the present invention, and it is possible to instantaneously ignite the pilot burner by rectifying the main power supply of the gas appliance without using a separate battery. Referring to Figure 3 and in detail as follows.

메인전원(AC)에 트랜스(T)와 브릿지회로(B) 그리고 콘덴서(C)로 된 통상의 정류회로부(1)를 접속하고 이의 출력단에는 밸브놉(5)에 부착된 캠(6)에 의해 동시 동작되는 마이크로 스위치(2)와 타이머(3) 그리고 다이오드(D)를 통하여 열전대(TC)와 MPU(4)를 병렬 접속하여서 된 것으로, 도면중 미설명부호 7은 파이롯트 버어너, 8은 점화 스파크 플러그, 9는 열전대와 MPU(4)사이에 연결된 안전장치이다.A normal rectifier circuit portion (1) consisting of a transformer (T), a bridge circuit (B), and a capacitor (C) is connected to the main power source (AC), and at its output end by a cam (6) attached to the valve knob (5). The thermocouple (TC) and the MPU (4) are connected in parallel through a micro switch (2), a timer (3) and a diode (D) which are operated simultaneously. In the drawing, reference numeral 7 denotes a pilot burner, 8 denotes an ignition. The spark plug, 9, is a safety device connected between the thermocouple and the MPU (4).

이와같이 구성된 본 고안은 사용자가 밸브놉(5)을 점화위치로 턴시키면 밸브놉(5)에 부착되어 있는 캠(6)이 회전되면서 이 캠(6)에 의해 눌러져 있던 마이크로스위치(2)의 접점이 NC에서 NO로 원위치되어 마이크로스위치(2)가 온됨과 동시에 이 마이크로 스위치(2)와 연동되는 타이머(3)가 온되므로 즉, 타이머(3)의 접점이 NO에서 NC로 이동되므로 정류회로부(1)를 통하여 정류된 직류전류가 다이오드(D)를 거쳐 MPU(4)에 인가되고 이에 따라 MPU(4)의 솔로노이드밸브가 가스통로를 열어 점화스파크 플러그(8)에 불꽃이 튀면서 파이롯트 버어너(7)가 순간점화됨과 함께 열전대(TC)가 가열되기 시작한다. 이와같이 순간 점화된 후에는 열전대(TC)가 충분히 가열될 수 있도록 타이머(3)가 설정된 시간동안 온되어 있다가 설정시간이 완료되면 접점이 NC에서 NO로 이동되어 오프되므로 충분히 가열된 열전대(TC)에서는 기전력이 발생되는 것이다.According to the present invention configured as described above, when the user turns the valve knob 5 to the ignition position, the cam 6 attached to the valve knob 5 is rotated and the contact of the micro switch 2 pressed by the cam 6 is rotated. Since the micro switch 2 is turned on at this NC as NO and the timer 3 interlocked with the micro switch 2 is turned on, that is, the contact point of the timer 3 is moved from NO to NC. DC current rectified through 1) is applied to MPU (4) via diode (D), so that the solenoid valve of MPU (4) opens the gas passage and sparks on the spark spark plug (8). The thermocouple TC starts to heat up as (7) flashes instantaneously. After the momentary ignition, the thermocouple TC is turned on for a predetermined time so that the thermocouple TC can be sufficiently heated. When the set time is completed, the contact is moved from NC to NO and turned off. In the electromotive force is generated.

여기서, 타이머(3)의 출력단에 접속된 다이오드(D)는 열전대(TC)에서 발생된 기전력이 타이머(3) 쪽으로 인가되어 저항을 받을 경우에 열전대(TC)의 기전력이 떨어지는 것을 방지하기 위하여 접속된 것이다.Here, the diode D connected to the output terminal of the timer 3 is connected to prevent the electromotive force of the thermocouple TC from dropping when the electromotive force generated in the thermocouple TC is applied to the timer 3 to receive a resistance. It is.

또한, 소화시에는 밸브놉(5)을 소화위치로 턴시키면 캡(6)이 점화시와 역방향으로 회전되어 마이크로스위치(2)의 접점이 다시 눌러져 NO에서 NC로 이동되므로 마이크로스위치(2)가 오프됨과 동시에 타이머(3)의 접점은 NO단자에서 NC단자로 이동하므로 타이머(3)가 온되고, 이러한 상태에서 재 점화시 전술한 바와같은 작동을 계속하여 할 수 있는 것이다.In addition, when extinguishing, when the valve knob 5 is turned to the extinguishing position, the cap 6 is rotated in the opposite direction to the ignition position, and the contact of the micro switch 2 is pressed again to move from NO to NC. Simultaneously with being turned off, the contact of the timer 3 moves from the NO terminal to the NC terminal, so that the timer 3 is turned on, and in this state, the operation as described above can be continued.

이상에서와 같이 본 고안은 가스기기의 메인전원(AC)을 이용하여 밸브놉(5)을 한번 작동시켜 파이롯드 버어너(7)를 순간 점화시킬수 있어 제품의 사용이 더욱 편리해지는 효과가 있다.As described above, the present invention can operate the valve knob 5 once by using the main power source (AC) of the gas appliance, thereby igniting the pilot burner 7 at an instant, thereby making the use of the product more convenient.
