  In addition, regardless of whether or not the combustion signal is output from the combustion sensor 24, when the ON signal is not output from the timer switching key 322, the notification mode is executed by the control unit C2.

  When the plus key 3a is operated to change from the initial value (0 minutes) of the signal output time set in the notification mode to the signal output time to be notified (hereinafter referred to as “notification time”), the timer function unit Ts The difference between the counter value accumulated every time (for example, every minute) and the notification time, that is, the monitoring of the remaining time of the notification timer is started, and the notification is made when the difference between the counter value and the notification time becomes zero. A notification sound is output from the output unit 34.

  Thus, if the grill burners 21 and 21 are to be automatically extinguished at a heating setting time suitable for cooking, the timer switch key 322 is turned on and the plus key 3a or the minus key 3b is operated. If the heat setting time (for example, 8 minutes) is set, the timer cooking mode is executed by the control unit C2, and the fire can be automatically extinguished at the heat setting time. Further, if the user forgets to operate the plus key 3a or the minus key 3b after the ignition, the safety timer mode is executed by the auxiliary control unit Cm, and the grill burners 21 and 21 are automatically extinguished. It can prevent being left for a long time in a burned state.

  On the other hand, if ignition is performed with the timer switch key 322 not turned on, the safety timer mode is executed by the auxiliary control unit Cm, and the fire is automatically extinguished when an overheating prevention time (for example, 20 minutes) of the grill 2 elapses. Therefore, even if the grill burners 21 and 21 are ignited without being aware of timer cooking, it is possible to prevent the heated object from being left in an overheated state.

  When it is desired to notify the cooking time of instant noodles, the notification time set by the notification mode can be notified by setting the notification time with the plus key 3a or the minus key 3b without turning on the timer switching key 322. .

In addition, the measurement of the remaining combustion time of the grill burners 21 and 21 is set to start when the fire extinguishing time is set by operating the plus key 3a or the minus key 3b. When heating is started after the preheating operation for heating or the empty baking operation for burning the oil adhering to the inside of the grill 2 or the grill, etc., it is measured from the time when the burner is ignited. Fire extinguishing time suitable for cooked foods can be easily set as compared to those. That is, when setting the fire extinguishing time suitable for the food, when the fire extinguishing time is measured from the time when the burner is ignited, the preheating time or the empty baking time is set to the fire extinguishing time suitable for the food (for example, 8 minutes). In this embodiment, the fire extinguishing time suitable for the cooked food is not considered in the present embodiment, whereas the time added (for example, 3 minutes) must be calculated and set each time. (For example, 8 minutes) may be set.
Note that the operation of the gas stove according to the second embodiment exemplifies the control operation of the grill 2, but when the operation of the stove 1 is controlled, the heating setting time suitable for the cooked food is the same as the control operation of the grill 2. If it is desired to extinguish the burner 11 automatically, the ignition is performed with the timer switching key 322 turned on, and the heating set time (for example, 9 minutes) is set by operating the plus key 3a or the minus key 3b. For example, the timer cooking mode is executed by the control unit C2 and can be automatically extinguished during the heating setting time. If the user forgets to operate the plus key 3a or minus key 3b after the ignition, the safety timer mode is executed by the auxiliary control unit Cm, and the grill burners 21 and 21 are automatically extinguished. It can be prevented from being left for a long time in the state.

  On the other hand, if the ignition is performed with the timer switching key 322 turned off, the safety timer mode is executed by the auxiliary control unit Cm, and the fire is extinguished if the overheating prevention time (for example, 120 minutes) of the stove 1 elapses. Even if the burner 11 is ignited without being aware of cooking, it is possible to prevent the heated object from being left in an overheated state.

  The measurement of the remaining combustion time of the stove burner 11 is also set to start from the time when the fire extinguishing time is set by operating the plus key 3a or the minus key 3b, similarly to the control operation of the grill 2. When heating the cooked food after preheating the pan or frying pan used in the stove 1 in advance, cooking is easier compared to what is measured from when the burner is ignited. A fire extinguishing time suitable for the object can be set.
