Abstract
PURPOSE:To ensure enough warm feeling in lying on or below an electric blanket and save consumption power by determining preheating time depending upon room temperature via detection thereof. CONSTITUTION:The temperature of the room wherein an electric blanket is used, is inputted as a temperature signal to a microcomputer 10 via a thermistor 12 arranged within the blanket. The microcomputer 10 operates timer control time depending upon the room temperature and controls a thyristor 15 to turn ON and OFF until the termination of the operated timer control time via a comparison between a temperature signal obtainable as the voltage of a temperature sensing circuit 22 and the constant predetermined temperature. When timer operation terminates or there is no timer control demand signal, a comparison is made between a temperature signal obtainable as the voltage of a resistor 16 and a temperature signal from the temperature sensing circuit 22, thereby controlling the thyristor 15. As a result, pertinent preheating can be made regardless of a room temperature level.
