[0032]

As described above, the ironing device of the present invention can be used for a long period of time or accumulated in water by driving the electric motor by selecting an arbitrary voltage according to the difference from the reference time. Even if the water supply / drainage capacity decreases, the water supply / drainage capacity can be kept constant.

Therefore, the tank can always be used from a full state, water is cut off during ironing and steam spouts are interrupted, and drainage is incomplete, leaving water in the tank of the iron body for a long period of time. It is possible to always iron in a stable manner without the water rotting due to the storage of the odor and the generation of an offensive odor, or the steam in the iron body being blocked during the vaporization of the water to prevent steam from being generated.

Further, by driving the electric motor at a high voltage for a predetermined time at the beginning of use and then at a low voltage, water can be quickly sucked up from the water storage tank even when there is no water in the pump of the water supply / drainage device. At the same time, after the water reaches the pump, the rotation speed can be suppressed and the operating noise can be reduced without lowering the water supply / drainage capacity.

Therefore, it is possible to comfortably iron by reducing the annoying noise of the electric motor.
