  • Patent number: 9515498
    Abstract: A temperature detection unit detects the temperature of a power plug. A control unit stops electric conduction to a battery when the detected temperature detected by the temperature detection unit is equal to or higher than a predetermined specified temperature (T1). The control unit recovers the electric conduction to the battery when the detected temperature detected by the temperature detection unit decreases to a specified temperature (T2) or lower, the specified temperature (T2) being lower than the specified temperature (T1).

  • Patent number: 5117092
    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.
