Estimating the term…
An ironing system (500) comprises an iron (510) with a soleplate (512) comprising an induction heatable material. The ironing system (500) further comprises a unit (520, 530) that includes at least one induction coil (540) and a device (550). The induction coil (540) charges the iron (510) whereas the device (550) detects the temperature of the soleplate (512) by sensing a change in current flowing through the induction coil (540) or by sensing a change in voltage across the induction coil (540). The current or voltage changes as self inductance of the induction coil (540) changes with magnetic permeability of the soleplate (512) as a function of its temperature. The device (550) switches the induction coil (540) on or off depending on the detected temperature.
An ironing system comprising:
A unit for controllably heating an iron including a soleplate comprising an induction-heatable material, said unit including at least one induction coil and a device, said induction coil being configured for charging said iron and said device being configured for detecting an ironing temperature of said soleplate by sensing at least one of a change in current flowing through said induction coil and a change in voltage across said induction coil, said change in current or voltage being caused by a change in self inductance of said induction coil, said change in self inductance further being caused by a change in magnetic permeability of said soleplate as a function of said ironing temperature, said device being further configured for switching said induction coil on or off depending on the ironing temperature.
An iron including a soleplate comprising an induction-heatable material for use with a unit including at least one induction coil and a device, said induction coil being configured for charging said iron and said device being configured for detecting an ironing temperature of said soleplate by sensing at least one of a change in current flowing through said induction coil and a change in voltage across said induction coil, said change in current or voltage being caused by a change in self inductance of said induction coil, said change in self inductance further being caused by a change in magnetic permeability of said soleplate as a function of said ironing temperature, said device further being configured for switching said induction coil on or off depending on the ironing temperature;
