Then, the control unit of the steam generating and supplying device 1000 for the cooker reduces the size of the ignited flame by reducing the amount of gas supplied to the gas supply pipe 320 when the temperature of the water is higher than an appropriate temperature for generating steam.

In addition, when the water level is lowered to a level that the second water level sensor 510 cannot measure due to the steam generation, the control unit of the steam generating and supplying device 1000 for a cooker uses the water supply unit 120 to store water ( 110) is controlled to supply water.

Thus, when the water reaches the second water level sensor 510, the second water level sensor 510 measures the water level and transmits it to the control unit of the steam generating and supplying device 1000 for the cooker.

That is, the second water level sensor 510 measures the low water level.

Then, when the water reaches the first water level sensor 500, the first water level sensor 500 measures the water level and transmits it to the controller of the steam generator and supply device 1000 for the cooker.

That is, the first water level sensor 500 measures the high water level.

Then, the control unit of the steam generating and supplying device 1000 for the cooker stops supplying water through the water supply unit 120 .

Also, when water is supplied, the blocking member 520 prevents air bubbles formed on the upper surface of the water from contacting the first and second water level sensors 500 and 510 while the water is heated.

In addition, the ultrasonic vibration generating device 600 vibrates the water filled in the water storage space 110 with ultrasonic vibration, so that the scale (remnant) attached to the inner surface of the water storage space 110 and the outer surface of the heating tank 200 ) and other foreign substances.

Here, the water containing foreign substances such as the scale (residue) is discharged through the water drainage unit 130 .

And, as shown in FIG. 10, when the steam is not excessively supplied to the cooker 1, the second steam exhaust unit 170 is opened through the opening and closing member to allow a portion of the steam to be supplied to the second steam exhaust unit. Discharge through base 170.
