BEST MODE FOR CARRYING OUT THE INVENTION In order to further clarify the structure and operation of the present invention described above, preferred embodiments of the cooking device of the present invention will be described below. FIG. 1 is an external view of a gas stove as an embodiment of the present invention. This gas stove includes a right stove section 10, a left stove section 20, and a grill section 30 for grilling fish and the like. Left and right stove section 10,
Reference numeral 20 denotes burners 11 and 21 for burning gas, ignition buttons 12 and 22 for igniting and extinguishing the burners 11 and 21, and heating power for adjusting the combustion amount of the burners 11 and 21. Adjustment levers 13 and 23 are provided. Further, the grill portion 30 is provided with a grill burner (not shown), an ignition button 32 for igniting and extinguishing the grill burner, and a heating power adjusting lever 33 for adjusting the combustion amount of the grill burner.

Next, the internal structure of this gas stove will be described. Here, since the right stove section 10, the left stove section 20, and the grill section 30 have substantially the same configuration, the right stove section 10 will be used for explanation here. FIG. 2 is a schematic configuration diagram of the right stove section 10. The right stove section 10 is a burner 11
And a gas supply passage 14 for supplying gas to the burner 11.
An ignition button 12 for igniting and extinguishing the burner 11, a fire power adjusting lever 13 for adjusting the combustion amount of the burner 11, and a controller 15 for controlling combustion. Further, in the gas supply passage 14, a magnet valve 16 which is opened by being pressed by the ignition button 12 and which is kept in the adsorption open state by being energized, and a valve which is opened by pushing the ignition button 12 and is then pushed. A main valve 17 that is closed by the above, and a needle valve 18 that slides in conjunction with the thermal power adjustment lever 13 and adjusts the amount of gas flowing to the burner 11 are provided.

A pin 19 is provided below the heating power adjusting lever 13.
Slide volume 19 whose electric resistance is determined by the position of a
Is provided. The pin 19a of the slide volume 19 is a groove 13b provided in the arm portion 13a of the heat control lever 13.
When the heat power is adjusted by the heat power adjusting lever 13, the pin 19a slides along the groove to change the resistance value of the slide volume 19. Therefore, the resistance value of the slide volume 19 becomes a value according to the combustion amount of the burner 11.

The controller 15 includes a CPU, a RAM, and a ROM which constitute a well-known arithmetic and logic operation circuit (not shown).
It comprises an input interface for inputting signals from various sensors, an output interface for outputting drive signals to various actuators, and the like. Further, a turning-off prevention timer that starts in conjunction with the ignition button 12 at the time of ignition is provided, and the timer time is changed according to the resistance value of the slide volume 19. This timer time is changed so that the larger the combustion amount of the burner 11, the shorter the timer time, and the longer the timer amount, the longer the combustion amount of the burner 11. The timer time may be set differently for each of the right stove section 10, the left stove section 20, and the grill section 30.

Next, the operation of the forget-to-cut prevention timer of the gas stove will be described with reference to the flowchart of FIG. When the ignition button 12 is pressed (S1), the main valve 17,
The magnet valve 16 is mechanically pushed open so that gas flows into the burner 11 and the burner 11 is ignited by an ignition device (not shown) (S2). At the same time, the controller 15 reads the resistance value of the slide volume 19 and responds to the value. The timer time is set (S3), and the forgetfulness prevention timer starts counting (S4). When the burner 11 starts burning,
A thermocouple (not shown) is heated to generate a thermoelectromotive force, and the thermoelectromotive force causes the controller 15 to confirm combustion of the burner 11 and energize the magnet valve 16 to keep the adsorption valve open state.

When the heat power is changed by the heat power adjusting lever 13 during combustion (S5: YES), the controller 15 resets the count of the forget-for-prevention timer (S6), and the timer time is based on the resistance value of the slide volume 19. The time is changed (S7) and the counting is started again (S8).

When the burner combustion state continues and the count of the forget-for-forgotten timer reaches the timer time (S9: YE
S), the controller 15 gives a notification by a buzzer,
Then, the energization of the magnet valve 16 is stopped and the magnet valve 16 is closed to extinguish the burner 11 (S10).

As described above, according to the gas stove of the present embodiment, the smaller the combustion amount of the burner 11 is, the longer the timer time is. Therefore, when long-time heating such as a stewed dish is required, it is automatically performed during cooking. The problem of extinguishing the fire can be reduced, and the larger the combustion amount of the burner 11, the shorter the timer time. Therefore, the safety is high even if the burner 11 forgets to extinguish it when burning with high heat. Further, when the heating power is changed, the timer time is changed and the forget-for-prevention timer is reset and restarted, so that the burner 11 is automatically extinguished even though the user is cooking. Such problems can be reduced. Moreover, the cost can be reduced by the structure in which the heat power adjusting lever 13 and the slide volume 19 are mechanically interlocked.

In the present embodiment, the timer time is changed by the slide volume 19 which moves in conjunction with the heat power adjusting lever 13. However, for example, a micro switch that is turned on when the heat power adjusting lever 13 is adjusted in the weak direction is used. A two-step switching configuration may be used in which the timer time is lengthened when the micro switch is turned on. Further, the heat control is not limited to the slide type heat control lever, and the heat control may be performed by rotation. Further, although the timer time is mechanically interlocked by the thermal power adjustment lever 13, the same effect can be obtained by electrically interlocking and changing the timer time when electrically controlling the thermal power. Also, if any of the right stove, left stove, or grill is being used at the same time, and if any of the operations such as thermal power adjustment is performed by the user, all of the operating forget The prevention timer may be reset. Further, in the present embodiment, the timer is reset when the heat power is adjusted, but the count may be continued without resetting the timer.

The embodiments of the present invention have been described above.
The present invention is not limited to these examples, but can be applied to, for example, an electric stove and can be implemented in various modes without departing from the scope of the present invention.

[0019]

As described in detail above, claim 1 of the present invention
According to the cooker described, even when performing a small amount of heat for a long time such as a stewed dish, the timer operation is set to a long time, so that the heating operation is automatically stopped even if cooking is being performed. It is safe because the timer time is set short when the amount of heat is large. In this way, by changing the timer time according to the heat quantity of the heating means, it is possible to achieve both safety and usability.

Further, according to the cooker of the second aspect of the present invention, the amount of heat of the heating means is changed, so that the user judges that the user has not forgotten to turn off and resets the forgotten-off prevention timer. By restarting, it is possible to reduce the trouble that the heating operation is automatically stopped by the forgetfulness prevention timer even during cooking, which is more convenient.
