Abstract
A cordless iron includes a stand and an iron body placeable on and detachable from the stand. The iron body has a sole plate. The sole plate of the iron body is heated when the iron body is placed on the stand. An electrically powered temperature sensor senses the temperature of the sole plate of the iron body and outputs a signal representative of that sensed temperature. An alarm device responsive to the signal outputted from the temperature sensor serves to indicate that the sensed temperature drops to or below a reference temperature. The temperature sensor is kept activated when the iron body is detached from the stand.

A cordless iron comprising:
- a stand;
- an iron body placeable on and detachable from the stand and having a sole plate;
- means for heating the sole plate of the iron body when the iron body is placed on the stand;
- means for deactivating the heating means when the iron body is detached from the stand, whereby a temperature of the sole plate of the iron body gradually drops when the iron body is detached from the stand;
- means for sensing the temperature of the sole plate of the iron body and outputting a signal representative of the sensed temperature of the sole plate of the iron body, said temperature sensing means comprising an electrically powered temperature sensor;
- means responsive to the signal outputted from the sensing means for, while the iron body remains detached from the stand, informing that the sensed temperature drops into a predetermined range;
- and
- means for keeping the sensing means activated to enable the sensing means to continuously sense the temperature of the sole plate of the iron body while the iron body remains detached from the stand;
- wherein the informing means is responsive to the signal which is currently outputted from the sensing means while the iron body remains detached from the stand.
