Title: Gas cooking device with grill
Inventor: YOSHIDA YUTAKA
IPC: F23N5/10
Filed: 1995-11-10
Abstract: PROBLEM TO BE SOLVED: To perform an accurate sensing of an ignited state of a burner, shorten a time period required for detecting ignition and improve an operating characteristic of the burner. SOLUTION: An ignition sensing part 8 detects a temperature in a grill. A first memory 1 stores a value in which an output value of an ignition sensing part 8 during igniting operation is multiplied by a first coefficient corresponding to a relation of value between the output value and a threshold value. In addition, a second memory 2 stores a value in which an output value of an ignition sensing part 8 during igniting operation is multiplied by a second coefficient. A timer 3 limits a time by a specified period of time ranging from an igniting operation.  During a time limiting operation of the time 3, a calculation processing part 4 judges that a burner is ignited due to the fact that an output value of the ignition sensing part 8 is increased more than the stored value of the second memory 2 and concurrently upon completion of the time limiting operation of the timer 3, a calculation processing part 4 judges that the burner is ignited due to the fact that the output value of the ignition sensing part 8 is increased more than the stored value in the first memory 1.
