The electric heater 9 of the steam generator 8 is arranged with the winding axes aligned, and each winding portion is alternately overlapped and bonded. The steam/water separator 10 is formed in a cylindrical shape,
Water supplied by the electromagnetic pump 6 is stored inside it. In addition, the steam generator 8 communicates with the steam water separator 10 through its water pipe portion 8a, so that the water level of the stored water is adjusted to the steam water separator 10 by the siphon principle.
By superheating the stored water at the same level with the electric heater 9, superheated steam is generated, and this superheated steam is ejected from the tip nozzle 19 of the hand tool 17 via the steam/water separator 8. I try to do that.
