らである。In the stop temperature setting means 12, the gas burner 1
At the time point t 0 when heating by 1 is started, the initial temperature is assumed to be an oil-cooked product and the stop temperature is an initial value TH 0 (259 ° C.).
Is set to. After that, the controller 8 controls the temperature sensor 7
At time t 2 , t 3 , and t 5 , the stop temperature is reduced stepwise based on the output of the above, and the stop temperature is lowered to the first stop temperature TH 1 set according to the type of food,
6 , the temperature detected by the temperature sensor 7 becomes equal to the first stop temperature TH 1 due to the heat of the grill portion 20,
Moreover, since the operation signal is output from the grill operation determination means 22, the stop temperature is raised by 10 ° C. (that is, the stop temperature is raised from the first stop temperature TH 1 to the second stop temperature TH 2 ). Therefore, even if the output of the temperature sensor 7 rises to the first stop temperature due to the influence of the heat of the grill portion 20, it is possible to prevent the gas burner 1 1 from being extinguished during cooking. After that, when the equilibrium state detecting unit 14 can detect the equilibrium state, a new stop temperature is set by the cooking product determination unit 11. Here, since the newly set stop temperature is set from the equilibrium temperature, the gas burner 1 1 is not extinguished due to the heat of the grill portion 20. This is because the rise in the temperature detected by the temperature sensor 7 due to the influence of the heat of the grill section 20 reaches a saturated state within a fixed time (several minutes), so the stop temperature is set to 10 ° C.
When the equilibrium state detecting means 14 can detect the equilibrium state after the temperature is raised, it is determined that the temperature rise due to the influence of the heat of the grill portion 20 has already saturated, and the stop temperature setting means 12
This is because the new stop temperature is obtained based on the equilibrium temperature.
