Abstract

PURPOSE:To enable a base surface temperature in using an iron to be kept at an optimum temperature for ironing by drive-controlling a heater so that a detection temperature due to a temperature-sensitive sensor may be a set temperature. CONSTITUTION:In a standby state, a base surface temperature is almost equal to the detection temperature of a temperature-sensitive sensor 4, and so the base surface temperature is kept at a set temperature T1. By a micro-computer 8, arithmetic is performed on the change rate of the detection temperature from the detection output of the temperature-sensitive sensor 4, and it is monitored whether a temperature gradient is suddenly changed or not. When ironing is actually started from the standby state, then the base surface temperature is suddenly lowered, and according to the lowering, the detection temperature of the temperature-sensitive sensor 4 is also lowered, and so a temperature fall rate Td is made greater than a value, and by the state discriminating function of the micro-computer 8, shift to an iron using state is discriminated. At the same time, by the set change function of the micro-computer 8, a control temperature is changed to a set temperature T2, and a heater 5 is drive- controlled.

At this time, the state determining means calculates the rate of change of the sensor's detection output, that is, the temperature gradient, and since the temperature of the base surface drops rapidly while the iron is in use, if the temperature gradient changes suddenly, the state is in standby mode. The transition from to the ironing state is determined.

As a result, the sensor mounting part of the base is maintained at a higher temperature than the set temperature, but the base surface is maintained at the set temperature due to the temperature difference caused by the difference in heat release between the sensor mounting part and the base surface when the iron is in use.

In addition, when the iron is switched from the ironing state to the standby state, the temperature drop on the base surface is significantly alleviated, and the ratio of the heater's on time to the heater's off time changes to become smaller. The transition to this state is determined, and the set temperature is returned to the original temperature by the setting change means.
