<p>PURPOSE:To reduce the cost, and also, to obtain a simple display design by displaying a detected temperature and a set temperature by one indicator. CONSTITUTION:The titled device is provided with a thermistor 1 for detecting a temperature, a volume 4 for setting a temperature, a first indicator 16 for displaying a detected temperature and a set temperature, a second indicator 17 for indicating the display contents by interlocking with the display contents of the first indicator 16, a display switch 13 for switching the contents outputted to the first indicator 16, a time 9 which is initialized whenever an operation for setting a temperature is executed and starts a counting operation, and a comparator 11 for comparing a count value of the timer 9 with a prescribed value, and inverting an output, when said value becomes the prescribed value, and by an output signal of the comparator 11, a display of the display switch 13 is switched. In such a way, since the display contents are indicated by the second indicator 17, a confirmation of the display contents of that time more convenient, and also, a confirmation error can be eliminated.</p> |
