<p>PURPOSE:To simplify the constitution 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 display switch13 for switching the contents outputted to the first indicator 16, a timer 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 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, usually a detected temperature is displayed, and when an operation for setting a temperature is executed, a set temperature is displayed, and unless the operation for setting a temperature is executed for a prescribed time, the set temperature is returned automatically to the original detected temperature, therefore, the use convenience is improved remarkably.</p> |
