By adopting the structure, the steam generator temperature sensor 4 is used for detecting and judging that the steam generator body 6 is subjected to twice dry burning, then the water supplementing controller 5 is used for analyzing the water level information of the water tank 1 detected by the water level sensor 2 during twice dry burning, and calculating to obtain the water consumption speed of the steam generator body 6 in the interval time of twice dry burning; inside water pump 3 pumped the water in water tank 1 to steam generator body 6, moisturizing controller 5 adjusted water pump 3's work load, then controlled water tank 1 to steam generator body 6's water injection speed, then set for the water injection speed and be equal to or be greater than the speed of consuming water slightly, just so can continuously supply sufficient water volume for steam generator body 6 to after the culinary art finished, steam generator body 6 inside also can not remain too much surplus water.
The first embodiment also comprises a temperature controller 7 and a steam box temperature sensor 8. The temperature controller 7 is fixed on the steam generator body 6 and is electrically connected with the steam generator temperature sensor 4, and the steam generator temperature sensor 4 transmits the detected temperature signal to the temperature controller 7. The temperature controller 7 comprises a kick type overheat protector, and is used for performing overheat protection on the steam generator body 6, when a fault occurs, the steam generator body 6 does not continuously dry-fire water supply for a long time, when the temperature rises to 200 ℃, the kick type overheat protector jumps off to stop heating the steam generator body 6, and after the fault is removed and the temperature is reduced to a specified value, the kick type overheat protector can recover the heating work of the steam generator body 6.
The steam box temperature sensor 8 is fixed on the steam box cavity 9. When the steam generator body 6 is dry-fired, enough steam cannot be generated to enter the steam box cavity 9, so that the temperature of the steam box cavity 9 begins to drop.
