JPS6460986A - Floor heating device - Google Patents

Abstract

PURPOSE:To prevent to leave the ON condition even though the cutting is failed and to realize an energy saving by making an electric carpet cut off after a specific time without exception when the carpet is turned on manually to continue to use it after the carpet is cut off by the operation of a timer. CONSTITUTION:In a floor heating device main body, a heater 1 and a temperature sensor 2 are incorporated, and a controller 4 compares the temperature signal from the temperature sensor 2 and the setting signal from a temperature setting member 3 to control the current flow to the heater 1 making the temperature of the floor heating device main body and the set temperature equal. And a timer 6 outputs a stop signal to the controller at a set time, a timer 7 is activated by the stop signals of the timer 6 and a timer 8 in a 5 minutes limit timing, and when the ON signal of a power supply switch 5 is detected before the ending of the count, the activating signal of the timer 8 is output. And when the timer 8 finishes the count in a one hour limit timing, it outputs a stop signal to the controller 4 to stop the current flow to the heater.
