According to this, when the cooking start switch 1 is "on" and the grill door is closed, as determined by the grill operation controller 34 in the microcomputer 3, the grill burner is ignited for a predetermined time according to the food. Continuing to detect whether the grill door remains closed while the grill automatic cooking is performed;

If the grill door remains closed as a result of the detection, completing cooking after a predetermined cooking time has elapsed;

As a result of the above detection, when the grill door is opened during the automatic cooking of the grill, the grill burner is extinguished, the timer 33 counting the automatic cooking time of the grill is stopped and the remaining time is memorized, the door is closed again within the predetermined time and the cooking starts. Detecting whether the switch 1 is again "on";

As a result of the above detection, if the door is not closed within the predetermined time and the cooking start switch 1 is not "on", the automatic cooking of the grill is stopped, and conversely, the door is closed within the predetermined time and the cooking start switch 1 is "on". "When the grill burner is re-ignited and the timer is started, the automatic grilling operation is continued for the remaining time while the door is continuously detected whether the door is opened or closed.

Referring to the effects of the device and method of the present invention made of such a configuration and process as follows.

First, when a user operates " on " the grill automatic cooking start switch 1 installed on the operation panel of the gas oven range, the grill operation control unit 34 in the microcomputer 3 uses the start switch recognition unit 31. Recognizing that the grill automatic cooking start switch (1) is in the "on" state and receives the output signal of the door opening and closing detection sensor (4) input through the door opening and closing recognition unit 32 to continue whether the grill door is closed or open You will be confirmed.

As such, when the output signal of the door open / close detection sensor 4 is input through the door open / close detection unit 5 and the door open / close recognition unit 32 to check the state of the grill door, the grill operation control unit 34 is closed. ), The grill burner ignition signal is outputted to the grill drive component part 7 through the grill driving part output part 35 and the grill driving circuit part 8, so that the burner is ignited, and the food is fed to the grill automatic cooking for a predetermined time. Cooking is done.

In addition, when the automatic cooking of the grill is made for a predetermined time as described above, the grill operation control unit 34 continuously receives the output signal of the door opening / closing recognition unit 32 in real time to draw the grill door by the user among the automatic cooking of the grill. Detects whether is opened or kept closed.

As such, when the grill operation control unit 34 continuously monitors the state of the grill door and maintains the closed state, it is possible to cook the food in an optimal state. You will complete the automatic cooking of the food.

However, as a result of the detection, if the grill door is opened by the user during the automatic cooking of the grill, that is, before the end of the predetermined time, the grill operation control unit 34 recognizes this and immediately extinguishes the grill burner to burn the flame of the burner. This prevents the occurrence of a safety accident such as a user being burned and stops the driving of the timer 33 which is counting the automatic cooking time to be grilled and stores the remaining time.

Thereafter, the grill operation control unit 34 detects whether the grill door is closed again within a predetermined time (for example, 5 minutes or more) and the cooking start switch 1 is "on" again.

As a result of the above detection, if the door does not close within a predetermined time and the cooking start switch 1 is not turned “on”, that is, the user opens the door during automatic cooking and leaves for more than 5 minutes, the cooking time is cleared and the automatic cooking of the grill is performed. It will stop.

On the contrary, if the user closes the door again within a predetermined time and "turns on" the cooking start switch 1, the grill operation controller 34 re-ignites the grill burner, starts the timer operation, and grills for the remaining time. The automatic cooking continues to detect whether the door is opened or closed.

Therefore, when the cooking is performed again after opening the door during automatic cooking of the grill and checking the contents, the cooking proceeds automatically for the remaining time even if the user does not input the remaining time, thereby greatly improving the operability and reliability of the product and the productability.

As described above, according to the present invention, a user selects the automatic cooking for a particular food and then presses a start button. Then, the automatic cooking for a predetermined time after the ignition is performed is performed. The burner is automatically extinguished when the grill door is opened due to a fire, etc., so that the user may be able to solve safety problems such as burns caused by the flame caused by the grill burner. If only the switch is operated, the automatic cooking of the grill is resumed for the remaining time after automatic ignition, so that the inconvenience of having to input the remaining time can be solved, which greatly improves the operability, reliability and commodity of the product, as well as the taste of the food. Automatic cooking in the optimal state.
