Abstract
The invention is directed to a steam iron (1) equippped with an electrically heatable soleplate (9) and having a residual heat warning device (16) which operates preferably independently of the line voltage and issues a flashing warning signal via a light emitting diode (17) when the temperature of the soleplate (9) exceeds a threshold temperature of about 60° C. Due to a capacitor which is chargeable during operation of the iron, a preferred warning system is operable also when the iron is disconnected from the supply after use.
Claims24
A pressing iron adapted to receive a line voltage, the pressing iron comprising:
- an electrically heatable soleplate heatable by connection to the line voltage;
- and
- a residual heat warning device for continuously issuing at least one temperature-independent warning signal for a predetermined time interval when the electrically heatable soleplate is disconnected from the line voltage, said predetermined time interval beginning and ending independently of any measured temperature of the soleplate.
A residual heat warning device for the issuance of at least one warning signal for a predetermined time interval, the warning device being associated with an electrically heatable heat emitting body of an electrical appliance, the warning device being activated when the electrically heatable heat emitting body is no longer being heated, the residual heat warning device comprising a signal, a timer and an electrical storage device, wherein the warning signal, the predetermined time interval and activation of the warning signal are all independent of any measured temperature of the electrically heatable heat emitting body.
An electrical appliance with at least one heat emitting body, the heat emitting body being heatable by connection with a line voltage, the electrical appliance further comprising a residual heat warning device operable independently of the line voltage and designed to deliver at least one warning signal for a predetermined time interval when the temperature of the heat emitting body exceeds a threshold temperature and the heat emitting body is disconnected from the line voltage, wherein the warning signal, the predetermined time interval and activation of the warning signal are all independent of any measured temperature of the electrically heatable heat emitting body.
