Abstract
PURPOSE: To inform a danger with an alarm when the thermistor is broken by controlling the heat source of cooking appliance in such a way that temperature of foods is detected by the thermistor and its detection signal causes the production of ultrasonic wave which is to be received by the receiver provided to the outside of oven.
CONSTITUTION: Let the output voltage of thermistor in a break, that in detecting temperature of 100°C and the reference voltage fed to the negative side of comparator 12 be VO, V100 and VP2 respectively. Whe VP2 is selected such that VO>VP2> V100, the comparator 12 inverts the output in a break of thermistor and feeds a signal to the AND gate 17 through the OR gate 16, the AND gate 17 provides an excitation signal P4 from the pulse generator 18 to the ultrasonic oscillation element 19 as an alarm signal P6 to make the element 19 generate ultrasonic wave continuously. At this time, the receiver 6 in the outside of heating room decides an alarm signal and stops the heat source.
