1 to 3, the preferred steam generator 10 of the present invention is provided with a metal vapor container 20 for storing a certain amount of water required for steam generation. Insulators, etc., not shown, are installed around the steam enclosure 20, and the insulation is formed in the form of being wrapped by the outer cylinder (5).

The steam container 20 is configured to seal all parts except the steam outlet 24 when the cover 50 made of metal is assembled into a cylindrical shape placed upward. The steam container 20 has a neck 23 having a management opening and closing port 22 thereon, and a steam outlet 24 for discharging the generated steam. The front of the neck 23 is provided with a leak-proof sealing 26 made of rubber or silicon.

The management opening and closing port 22 communicates with the inside of the steam container 20 as a hole formed in the neck 23 protruding to one side from the upper portion of the steam container 20. The cross-sectional size of the management opening / closing opening 22 is not disturbed at least by the inlet installation of the float valve 62 to be described later, and the worker's arm or the cleaning tool can be inserted into the breakwater receiving stand 40 and the internal cleaning or repair. It is determined within the range that there is free space.

The steam enclosure 20 is provided with one or more heaters 30 which are supplied with power to the water supplied to the steam enclosure 20 through a water supply pipe 60 to be described later and heated to a high temperature. In this embodiment, the heater 30 has a vertical cross shape at two places, and the heater 30 is configured in a long U-shape, but the present invention is not limited to this arrangement structure, shape, and number.

Inside the steam enclosure 20, a water-receiving sink 40 made of metal is installed. The water supply receiving stand 40 for a breakwater is located in the back of the management opening-closing opening 22, and receives the water discharged from the float valve 62. FIG.

The water sink 40 for the breakwater has a bottom portion 41, a side wall portion 42 entered from the bottom portion 41, and an opening 43 opened at the upper side of the side wall portion 42, and at this time, A plurality of balls 40a may be formed in any one or both of the bottom part 41 and the side wall part 42.

The front cover of the management opening and closing 22 is provided with a cover 50 detachably mounted to the neck (23). The front surface of the cover 50 is formed with a protruding pressing jaw 52 for pressing and close the leakage preventing seal 26. The cover 50 is fixed to the neck 23 via well-known fastening means (screws, bolts, etc.).

The cover 50 is connected to a water supply pipe 60 provided with a float valve 62 for adjusting the height of the water surface. At this time, the water supply pipe 60 is inserted into the cover 50 and welded to the whole circumference, and the float 64 of the float valve 62 is located above the breakwater receiving stand 40.

The operation of this embodiment configured as described above will be described.

When the cover 50 is mounted to the neck 23 of the steam container 20 as shown in FIG. 1, the float 64 of the float valve 62 is placed on the upper surface of the water supply base 40 for breakwater.

In this state, when water is supplied through the water supply pipe 60, the water is discharged into the water supply base 40 for the breakwater, and then the water is supplied into the steam container 20 through the water outlet hole 40a. Therefore, the inside of the steam container 20 is filled with water until the buoy 64 of the float valve 62 rises to a certain height as shown in FIG. 4 to block the outlet of the float valve 62.
