  • a mechanical temperature sensor is provided on the glass surface between the light emitting body 70 and the base surface 12 in order to prevent fabric damage, burning, and burns due to an abnormally high temperature state due to a failure or malfunction of the detection unit 40 or the control unit 20. Bimetal may be attached. This makes it possible to appropriately shut off the power supply.
  • the iron 10 may further include a notification unit that notifies information currently detected by the detection unit 50.
  • the notifying unit notifies the user of, for example, the temperature information of the dough estimated from the current temperature of the base surface 12 and the current temperature of the base surface 12.
  • the power supply unit 60 of the iron 10 is a secondary battery, it may be configured to notify the remaining battery level of the current secondary battery.
  • control unit 20 may perform control to increase the output of the light emitter 70 when the detection temperature is lower than the predetermined temperature by a threshold value or more.
  • the threshold is, for example, 20 ° C.
  • the irons related to this disclosure can be used as irons for removing wrinkles in commercial and household clothing.
