Abstract
The disclosure relates to an ironing device comprising an iron having an electrically heated and temperature regulated sole, at least one temperature sensor positioned in the vicinity of said sole, and a heater connected to an external electric supply. A temperature regulator is positioned remote from the iron for controlling the current supply to the heater and is responsive to the temperature sensor. The temperature sensor has at least one temperature-dependent resistor and at least one compensating resistor connected with the temperature-dependent resistor. An actual-valve input sets the desired temperature of the sole. The temperature-dependent resistor is also connected to the actual-value input. The overall value of resistance formed by the temperature-dependent resistor and the compensating resistor at a predetermined sole temperature is selected to correspond with the overall resistance of the actual-value input when the resistance of the variable resistance component has been selected to correspond to the predetermined temperature.
