2. Description of the Related Art Conventionally, a tray accommodated in a grill storage, a heating source such as a gas burner for heating the interior of the grill storage,
Performs various controls, including a heating switch for instructing start and stop of heating of the heating source, a grill timer for setting the heating time of the grill, a buzzer for notifying the end of heating, and a display for displaying the remaining time of the grill timer with a light emitting numeral. 2. Description of the Related Art A grill device in which a controller is arranged is known.

[0003] In consideration of a general heating time (for example, 8 minutes), the grill timer is set to 8 minutes as an initial value when the heating switch is operated, and is displayed on the display. By the way, when cooking fish, for example, while the inside of the grill is cold, the skin adheres to the grill and the appearance of the baked fish becomes unsightly. Therefore, it is desirable to cook by preheating. The following two methods are conceivable for performing preheating.

(A) The heating source is operated by operating the heating switch, and the time setting switch (eg, up / down switch) is operated to set the grill timer to a time (2 to 3 minutes) suitable for preheating. . When the set timer expires, the buzzer sounds (the heating source stops at this point), so the tray is pulled out of the grill storage. The fish is placed on the grill and stored in the grill storage again, and the heating switch is again operated to activate the heating source to start fish cooking (the grill timer at this time is the initial value of 8 minutes). .

(A) The heating source is operated by operating the heating switch, and after a time (2 to 3 minutes) suitable for preheating elapses, the tray is pulled out of the grill storage. Thereafter, the fish is placed on the grill and the saucer is stored in the grill storage again, and the time setting switch is operated to reset the grill timer to a time suitable for cooking (for example, 8 minutes), so that the fish is cooked. Start.

However, the operation of both the method (a) and the method (a) is complicated. It is also possible to program to execute the preheating mode before cooking, but it is not necessary to preheat when the inside of the grill storage is hot, such as when the fire is re-ignited immediately after the fire is extinguished.

Next, the operation of the grill G will be described with reference to the flowcharts shown in FIGS. The heating power of the grill burner 31 is set by a lever 33. In addition, in the case of a small fish, it is set to the "weak" side, and in the case of a large fish or preheating, it is set to the "strong" side.

When preheating is not performed, the tray 32 is pulled out of the grill storage 30 and the fish f is placed on the grill 322 and stored in the grill storage 30 again (the state of FIG. 2).
As shown in FIG. 4, the point / fire extinguishing button 34 is pressed (step s1). When preheating is to be performed, with nothing placed on the grill 322, the point / fire extinguishing button 3 as shown in FIG.
4 is pressed (step s1).

In conjunction with the pressing operation of the spot / extinguishing button 34, the safety valve 311 opens, the micro switch 341 turns on, the sparker 10 operates for a predetermined time, and a high voltage for ignition is applied to the ignition electrode 314. Then, the grill burner 31 is ignited (step s2).

When ignition is detected by the thermocouple 315 (YES in step s3), the flow advances to step s4. In step s4, the controller 4 causes the display 51 to display the initial value (8 minutes) of the grill timer time as “8”, starts the grill timer with the initial value of 8 minutes, and starts the 30-second timer. . When preheating is performed, the preheating switch 54 is pressed within 30 seconds (before a predetermined time elapses) after the “8” is displayed on the display 51.

At step s5, the microcomputer of the controller 4 detects whether or not the preheating switch 54 is pressed. If no pressing is detected, the process proceeds to step s6. If detected, the process proceeds to step s8.

At step s6, it is determined whether or not the 30-second timer has expired. If not (NO), the process proceeds to step s7. If yes (YES), the process proceeds to step s7.
Proceed to 12.

If preheating is unnecessary and the grill timer time is to be changed, NO in step s5 → step s

The controller 4 may be configured to reduce the heating power of the grill burner 31.

At step s11, the microcomputer of the controller 4 redisplays the initial value (8 minutes) of the grill timer time as "8", starts the grill timer, and turns off the LED 55.

At step s12, the microcomputer of the controller 4 determines whether or not the remaining time of the grill timer has reached one minute, and if it has reached one minute (YES), the flow proceeds to step s13. Note that NO in step s12 → step s
During the loop of 12, the timer setting switch (+) (-) 52, 5
By the pressing operation of 3, the grill timer is increased or decreased (15 minutes to 1
Minutes) is possible.

In order to urge the user to turn over and extend the grill timer as described below, the microcomputer of the controller 4 performs a turn-over notification in step s13.

(Flip-over operation)
The fish f is pulled out from the inside and the fish f of the grill 322 is turned over and stored in the grill storage 30 again.

(Extension operation of grill timer) In order to bake the opposite side of the fish f, the remaining time of the grill timer, which has one minute remaining, is reduced by operating the timer setting switches (+) (-) 52 and 53. Operation to extend the timer to, for example, 6 minutes.

(Notice of turning over) In order to urge the user to turn over, the buzzer 50 is sounded for 15 seconds as "beep, beep, beep, beep ...".

When the remaining time of the grill timer reaches 30 seconds (YES in step s14), the flow advances to step s15. In step s15, the buzzer 15 is sounded three times in a “beep beep” to notify the user of the fire extinguishing notice.

In step s16, the microcomputer of the controller 4 determines whether or not the grill timer time has been extended to one minute or more. If it is one minute or more (YES), the process returns to step s14, and the remaining one minute. If less than (NO), the process proceeds to step s17.

At step s17, it is determined whether or not the time of the grill timer has expired. If the time has elapsed (YES), the process proceeds to step s18. If the time has not elapsed (NO), the process returns to step s16.

Note that NO in step s14 → step s1
During the loop of No. 4 and NO in step s16 → NO in step s17 → in the loop of step s16, the grille timer is increased or decreased (15 minutes to 1 minute) by pressing the timer setting switches (+) (−) 52 and 53. Range) is possible.

At step s18, the microcomputer of the controller 4 closes the safety valve 311 to extinguish the fire of the grill burner 31, terminates the cooking, and sets the point / fire extinguishing button 3 off.
In order to urge the user to return to the fire extinguishing position of No. 4, the buzzer 50 is sounded continuously until the point / fire extinguishing button 34 is returned to the fire extinguishing position.

Next, advantages of this embodiment will be described. [A] If the inside of the grill storage 30 is cold and it is desired to perform preheating, the spot / fire extinguishing button 34 is operated to operate the grill burner 3.
1, the grill burner 31 is ignited, and the indicator 51
If the simple operation of operating the preheating switch 54 within 30 seconds after the grill timer is started is displayed, the preheating for 3 minutes can be performed.

Further, the completion of preheating is notified (step s).
10) When the tray 32 is pulled out of the grill storage 30 and the fish f is placed on the grill 322 and stored again in the grill storage 30, cooking can be started. At this time, since the grill burner 31 continues burning, there is no need to press the spot / fire switch 34.

When the preheating switch 54 is pressed before the predetermined time (30 seconds) elapses, the LED 55 is turned on, and the display on the display 51 is switched from the display of the remaining time of the grill timer to the display of the remaining time of the preheating timer. Since the number on the display decreases as time elapses, the user can easily know the switching to the preheating and how many minutes the preheating will be completed. Therefore, the gas table A to which the grill device G is assembled is easy to use.

[B] The grace period (20 seconds) required for pulling out the tray 32 from the inside of the grill storage 30 and placing the fish f on the grill 322 and storing it again in the grill storage 30 has elapsed since the end of preheating. At this point, the grill timer restarts, and when it restarts, the remaining time of the grill timer
1 is shown.

Therefore, the carry-in operation can be performed with a sufficient margin, and the cooking time can be easily known by looking at the display 51 after the carry-in operation is completed. If the loading operation is completed in about 20 seconds, the cooking time is about 8 minutes.

(C) When the preheating timer expires (combustion continues), it is necessary to pull out the tray 32 from the grill storage 30, place the fish f on the grill 322, and store it again in the grill storage 30. As the end of the grace period of 20 seconds (preferably in the range of 10 seconds to 50 seconds) is approached, the controller 4 blinks the LED 55 so that the blinking cycle is accelerated, and sets the buzzer 50 so that the ringing sound is increased. It is a configuration to make a sound. Therefore, it is possible to prompt the user to complete the loading operation within the grace period.

Next, a second embodiment of the present invention will be described.
5, 8, and 9) will be described with reference to FIGS. As shown in the figure, the grill H is equipped with gas stoves 1, 2
