An ironing system () comprises an iron () with a soleplate () comprising an induction heatable material. The ironing system () further comprises a unit () that includes at least one induction coil () and a device (). The induction coil () charges the iron () whereas the device () detects the temperature of the soleplate () by sensing a change in current flowing through the induction coil () or by sensing a change in voltage across the induction coil (). The current or voltage changes as self inductance of the induction coil () changes with magnetic permeability of the soleplate () as a function of its temperature. The device () switches the induction coil () on or off depending on the detected temperature.

Induction ironing system

A soleplate includes a metallic layer, a non-ferromagnetic layer and a ferromagnetic layer sandwiched between the metallic layer and non-ferromagnetic layer. The soleplate is used in an induction heating-based cordless iron. The electromagnetic field from an induction coil located in a stand, where the iron rests and gets charged, can pass beyond the non-ferromagnetic layer and heat the ferromagnetic layer efficiently. The non-ferromagnetic layer that is forming an ironing plate ensures a uniform heat transfer to the metallic layer for good steaming performance for effective cordless ironing.

Soleplate

A steam ironing device () provides an ionized steam output using an ionizing arrangement (). The ionization process, in particular the high energy electric discharge used for ionization, breaks down steam particles into finer particles. As a result, a greater proportion of the steam particles generated can penetrate into the fabric of the garment being ironed, to improve fabric treatment and fabric moistening. Air ionization can also be used. The ionization process is improved by limiting the temperature of the steam.
