JPS57188962A - Temperature control device for electric kotatsu - Google Patents

Abstract

PURPOSE:To effect the temperature control at a table side to facilitate to use it by a constitution wherein a control signal from a temperature control signal originating section provided at the table side is received at the receiving section of a framework side to operate a heating body temperature control means. CONSTITUTION:When the connection of an electric source of the framework 3 for the foot warmer is effected, the signal 21 from the originating section at the foot warmer side is received by a coil iron core 7 on the table 1, an A.C. signal is generated in a coil 8, a luminous element 23 is luminated through transistor circuits 9, 10, and the putting ON of the electric source is indicated. At the same time, transistors 10, 12, 13 are operated and an electric current is supplied from a battery 20 to a monostable multivibrator 5. The monostable multivibrator 5 generates a pulse determined by a temperature setting variable resistor 4 and a capacitor 27, the signal 22 is transmitted to the foot warmer side through a nonstable multivibrator 6 and th coil iron core 7 and the temperature is controlled through the receiving section of the foot warmer. Thus, the temperature may be controlled at the table side.
