When 4 lamp heaters are connected in parallel), each device in the circuit, such as thermostat or energy regulator, is welded or black foreign matter (oxide or carbide) when used for a long time. ) Is a decisive factor in shortening the life of the cooker.
이에 본 고안은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로 이를 첨부된 예시도면에 의거하여 상세히 설명하면 다음과 같다.Accordingly, the present invention has been devised to solve the above problems and will be described in detail based on the accompanying drawings.

제4도는 본 고안에 따른 적외선 조리기회로의 초기전류파형도로서 Ii는 초기 돌입전류이고, In은 정상전류이다.4 is an initial current waveform diagram of an infrared cooker circuit according to the present invention, where Ii is an initial inrush current and In is a steady current.
제1도 및 제2도에서 서로 병렬접속된 할로겐 램프히터(2, 2')에 석영관 니크롬 히터(1)를 직렬접속시킨 것은 전원인가시 할로겐 램프히터(2, 2')의 저항치는 초기 저항치에 비해 다수 배가 증가됨에 반해 석영관 니크롬 히터(1)는 거의 변화되지 않은 특성을 이용하여 전원인가 직후의 돌입전류를 최소화시키기 위함인데 그 측정치 및 계산치는 아래와 같다.In FIG. 1 and FIG. 2, the quartz tube nichrome heater 1 is connected in series to halogen lamp heaters 2 and 2 'connected in parallel to each other. The quartz tube nichrome heater 1 is to minimize the inrush current immediately after the power is applied by using the almost unchanged characteristics, while the number of times increases compared to the resistance value.
적외선 조리기의 정격전압이 220V, 정격소비전력이 1200W, 각 할로겐 램프히터(2, 2')의 저항치(R2, R2')가 각각 2.6Ω, 석영관 니크롬 히터(1)의 저항치(R1)가 13.76Ω일때 ＜전원인가 전, 또는 전원인가 직후＞The rated voltage of the infrared cooker is 220 V, the rated power consumption is 1200 W, the resistance values R 2 and R 2 ′ of the halogen lamp heaters 2 and 2 ′ are 2.6 kΩ respectively, and the resistance value R of the quartz tube nichrome heater 1 (R). 1 ) is 13.76Ω <before or immediately after power on>
R1=13.76ΩR 1 = 13.76 Ω
R2//R2'=1.3ΩR 2 // R 2 '= 1.3Ω
이고, 석영관 니크롬 히터(1)의 전압강하(VR1), 할로겐 램프히터(2, 2')의 총전압강하(VR2//R2') 및 전압강하(Vt)가 각각And the voltage drop V R1 of the quartz tube nichrome heater 1, the total voltage drop V R2 / R2 ' and the voltage drop Vt of the halogen lamp heaters 2 and 2', respectively.
VR1=74VV R1 = 74 V
VR2//R2'=141VV R2 // R2 ' = 141 V
Vt=216VVt = 216V

한편, 석영관 니크롬 히터(1)가 없을시에는 그 측정치 및 계산치가 아래와 같다.On the other hand, when there is no quartz tube nichrome heater 1, the measured value and the calculated value are as follows.

상술한 바와 같이 전원인가 직후의 전류 즉, 돌입전류와 전원인가후의 전류 즉, 정상 전류와의 바가 본 고안에 의한 경우에는 Ii : In=14.34 : 5.56 즉, 돌입전류의 약 2.5배임에 불과하여 회로내 각 소자에 무리가 따르지 않게 되나, 이에 반하여 석영관 니크롬히터(1)를 적용하지 않은 종래의 경우에는 Ii : In=166 : 5.56 즉, 돌입전류가 정상전류의 약 29.86배에 달하게 되어 회로내 각 소자에 큰 무리가 따르게 된다.As described above, in the case where the current immediately after the power is applied, that is, the current after the power is applied, that is, the normal current, is according to the present invention, Ii: In = 14.34: 5.56, that is, about 2.5 times the inrush current. On the contrary, in the case where the quartz tube nichrome heater 1 is not applied, Ii: In = 166: 5.56, that is, the inrush current reaches about 29.86 times the normal current. There is a big crowd on each device.
이러한 돌입전류억제 부재로서는 본 고안에 따른 일실시예인 석영관 니크롬히터(1)뿐만 아니라 그외에도 많은 것들이 있을 수 있다.As the inrush current suppressing member, there may be many others as well as the quartz tube nichrome heater 1 which is an embodiment according to the present invention.
이상으로부터 알 수 있는 바와 같이 본 고안은 전원인가 직후의 돌입전류를 최소한으로 억제하여 회로내 각 소자의 접점용착등의 손상방지 및 수명연장을 도모할 수 있게되는 등의 장점이 있다.As can be seen from the above, the present invention has the advantage of minimizing the inrush current immediately after the power is applied to prevent damage such as contact welding of each element in the circuit and to extend the life.
