Therefore, high-temperature steam is guided and ejected, and sterilization and disinfection purification work is performed by the high-temperature steam.

The pressure at which the pressure reducing valve 50 reduces the pressure is set to be higher than the discharge pressure of the pressure valve 40, so that, under normal operating conditions, steam does not discharge from the pressure reducing valve 50, but the pressure decreases. If the steam discharging action of the valve 40 is too slow, the steam pressure in the water tank 20 becomes excessively high, and when the steam reaches a predetermined pressure, the steam presses the pressure reducing valve piston 52 through the pressure reducing hole 56 to reduce the pressure. In this case, the steam is discharged from the pressure reducing valve inner lid 51 to reduce the pressure, thereby improving the safety.
