度検知手段。 A thermistor 1 that detects temperature, an A/D conversion circuit 3 that inputs the temperature change detected by this thermistor 1, and a temperature at a certain point after inputting multiple times at regular intervals from this A/D conversion circuit 3. A function that determines that there is no change in the currently detected temperature when T6 returns to the temperature T1 at the beginning of input, and
The temperature currently detected when the temperatures T 7 , T 8 , T 9 , T 10 input multiple times at regular intervals from the /D conversion circuit 3 differ from the temperature T 1 at the beginning of the input is defined as the temperature at the beginning of the input. Temperature detection means comprising a microcomputer 4 having a function of determining the temperature T10 closest to T1 .
