Abstract

[목적][purpose]

마이크로컴퓨터를 사용하지 않고, 피가열물의 과가열상태나 서미스터의 단선상태를 서미스터를 포함하는 회로의 출력전압에서 비교회로등을 이용한 간단한 구성으로 정밀도 높게 검지할 수 있고, 이것에 대응한 가열원의 작동정지를 정확하게할 수 있는 가열장치를 제공한다.It is possible to detect the overheated state of the object to be heated or the disconnection state of the thermistor at a high precision with a simple configuration using an output voltage of a circuit including a thermistor using a comparator circuit and the like without using a microcomputer, A heating device capable of precisely stopping operation is provided.

[구성][Configuration]

피가열물의 온도를 검출하기 위하여 서미스터(5)에 접속한 저항회로(14)의 저항값을 대소 2종류의 저항값으로 소정시간마다 상호 절환하면서, 서미스터(5)의 출력전압을, 비교회로(16,17)에 의하여 각각 과가열상태를 검지하기 위한 기준값과비교함과 동시에 비교회로(18)에 의하여 서미스터(5)의 단선상태를 검지하기 위한 기준값과 비교한다. 비교회로(16,17)에의한 과가열상태의 검지신호 혹은 비교회로(18)에 의한 단선상태의 검지신호가 상기 소정시간보다도 긴 시간 계속해서 출력되었을 때에 지연회로(19 또는 20 또는 21)에서 정지지령신호를 출력하여 가열원의 작동을 정지시킨다.The output voltage of the thermistor 5 is compared with the output voltage of the comparator circuit 5 while the resistance value of the resistance circuit 14 connected to the thermistor 5 is switched between large and small two kinds of resistance values at predetermined time intervals to detect the temperature of the object to be heated 16 and 17 with the reference value for detecting the heating state, and at the same time, with the reference value for detecting the disconnection state of the thermistor 5 by the comparison circuit 18. When the detection signal of the overheating state by the comparator circuits 16 and 17 or the detection signal of the disconnection state by the comparator circuit 18 continues to be output for a time longer than the predetermined time, the delay circuit 19 or 20 or 21 A stop command signal is outputted to stop the operation of the heating source.
