Abstract
In the cordless iron assembly, an iron (10) includes a base (11), a heater (12) for heating the base (11), a thermosensitive element (13) for sensing the temperature of the base (11), a temperature detecting circuit (14), and terminals (P1, P2, P3, and P4), and a stand (15) including a terminals (P5, P6, P7, and P8), a pulse detecting circuit (16), a temperature control circuit (17), and a cord (18). The temperature detecting circuit (14) produces a pulse signal in accordance with the temperature signal outputted from the thermosensitive element (13). The pulse signal detecting circuit (16) receives the pulse signal, and outputs the pulse signal to the temperature control circuit (17). By the temperature control circuit (17), the temperature of the heater (12) is controlled in accordance with the plate signal whereby the base temperature of the iron (10) can be correctly controlled when the iron (10) is supported on the stand (15). The pulse signal can be communicated by an electrical circuit or an optical link, possibly including an infra-red emitting diode or can be superimposed on the current supply connecting to the heater.
