The controller according to any one of claims 3 to 6, wherein the controller is Counting the elapsed cooking time, when the set cooking time has elapsed, by controlling the switching valve to reduce the amount of fuel supplied to the minimum amount of heating device for cooking. delete In the driving method of the heating device for food cooking comprising a controller for generating a spark by controlling the ignition unit, a temperature sensing unit for sensing the temperature and a switching valve for adjusting the amount of fuel burned, the controller, An ignition step of opening a switching valve to discharge fuel and driving the ignition unit to ignite the discharged fuel when a driving signal is received; A temperature sensing step of comparing the set heating temperature with the detected heating temperature to increase or decrease the amount of fuel discharged as the detected temperature is higher or lower than the set heating temperature, thereby maintaining the heating temperature at the set temperature; A counting step of comparing the set cooking time with the current time; When the cooking time set in the count step elapses, a fire extinguishing step of extinguishing the flame by cutting off the supply of the discharged fuel, The ignition step Displaying a start of driving as a time or an alarm when a driving signal is received; Turning on the ignition unit for a predetermined time and determining whether the ignition unit is in normal operation; When the ignition unit is operated normally, controlling the switching valve to supply fuel with a maximum amount of supply possible; A spark ignition checking step of checking whether a flame is ignited when fuel is supplied; In the flame ignition determination step, if it is determined that the flame is ignited, heating the food cooking, characterized in that for controlling the switching valve so as to supply the fuel corresponding to the maximum supply amount by controlling the switching valve Method of driving the device. The method of claim 9, wherein the normal operation plate step of the ignition unit If the ignition unit does not operate normally, the method of driving a heating device for food cooking, characterized in that it further comprises the step of repeatedly turning on the ignition unit and confirms the normal operation. The method of claim 9, wherein in the spark ignition check step, If the flame is not ignited, the method of driving a heating device for food cooking, characterized in that it further comprises the step of repeatedly turning on the ignition portion, and confirming the occurrence of the flame. The method of claim 9, wherein in the switching valve control step, And after the switch valve is turned on and the fuel is supplied, controlling the switch valve to cut off the supply of fuel if a flame is not detected. The method of claim 9, wherein the temperature sensing step In the switching valve on step, when the flame is detected, detecting the heating temperature of the food and comparing with the set temperature; And in the temperature comparison judgment step, increasing or decreasing the amount of fuel burned by controlling the switching valve so that the sensed heating temperature is maintained as a set temperature. The method of claim 9, wherein the digestion step When the cooking time set in the counting step has elapsed, controlling the switching valve to reduce the amount of fuel to reduce the intensity of the flame; And after the fuel reduction step, determining whether an end signal is received, and when the end signal is received, controlling the switching valve to cut off fuel.
