[0002]

2. Description of the Related Art In a heating device for cooking such as a gas stove or a grill, combustion may be interrupted due to misfire or the like.
In such a case, the user generally restarts cooking after the circumstances leading to the interruption of the combustion are resolved. However, when restarting cooking as described above,
The user cannot know how much the object to be cooked is heated by the interruption of the combustion, in other words, how far the cooking is progressing. For this reason, after restarting cooking, it is difficult to know how much heating should be performed, heating is often excessive, time for cooking is wasted, and in extreme cases, cooking itself may fail.

[0003] Conventionally, in the above-mentioned cooking heating device, there is known a device that sounds a buzzer to inform the user when combustion is interrupted due to misfire during cooking. Also,
Japanese Examined Patent Publication No. 7-43139 discloses that when a misfire occurs during cooking, the gas solenoid valve is electrically closed and then the user mechanically shuts off the gas (mechanical valve). , A gas cooker in which a buzzer sounds to notify a user.

However, in the above-mentioned prior art, the former merely informs the user of the fact of misfire, and the latter aims to prevent gas leakage after the misfire, and restarts cooking after the misfire. When trying to do so, there is an inconvenience that it is not possible to know the heating state of the food to be cooked before the misfire.

[0005]

DISCLOSURE OF THE INVENTION The present invention eliminates such inconvenience, and when heating is interrupted during cooking,
It is an object of the present invention to provide a cooking heating device capable of notifying a user of how much an object to be cooked is heated before the heating is interrupted.

[0006]

In order to achieve the above object, the cooking heating device of the present invention comprises a heating source for heating an object to be cooked with combustion gas, and heating control means for controlling heating by the heating source.

BEST MODE FOR CARRYING OUT THE INVENTION Next, embodiments of the present invention will be described in more detail with reference to the accompanying drawings. FIG. 1 is a system configuration diagram showing an example of a heating device for cooking according to the present invention.

The cooking device of the present embodiment is a gas stove 1 as shown in FIG. 1, and a stove burner connected to a gas supply conduit 3 via a solenoid valve 2 for controlling the supply of fuel gas. 4 is provided, and ignition and extinguishing are performed by a point / fire extinguishing knob having a point / fire extinguishing switch 5, and the heat power of the stove burner 4 is adjusted by a heat power adjusting cock (not shown). An ignition electrode 7 and a thermocouple 8 for detecting a flame are provided near the flame mouth of the burner 4.

The gas stove 1 is provided with a controller 9 for controlling its combustion. The controller 9
Combustion control means 10 having a microcomputer (not shown) connected to the solenoid valve 2, the point / fire extinguishing switch 5, the ignition electrode 7 and the thermocouple 8, a timer 11 connected to the combustion control means 10, a combustion control means 10, a memory 12 connected to a timer 11 is provided, and a piezoelectric buzzer 13 as an informing means is connected to the combustion control means 10.

Next, the operation of the gas stove 1 will be described.

First, when the user presses the point / fire extinguishing knob, the main valve (not shown) is mechanically opened, the point / fire extinguishing switch 5 is turned on, and the combustion control means 10 opens the solenoid valve 2 to supply gas. Fuel gas is supplied from the conduit 3 to the stove burner 4 and the ignition electrode 7 is operated to cause the stove burner 4 to operate.
The combustion is started by igniting the. In addition, points
Even if the pressure of the fire extinguishing knob is released, the original valve is held open.
During the combustion, the opening of a heat power adjusting cock (not shown) is adjusted according to the setting of a heat power adjusting knob (not shown), and the pot P applied to the gas stove 1 is heated by the heat power set by the heat adjusting knob.

On the other hand, when a flame is detected by the thermocouple 8,
The combustion control means 10 assumes that the combustion has started,
The timer 11 is activated. The timer 11 measures the time as the duration of heating while the flame is detected by the thermocouple 8. Then, the measured value is output from the timer 11 to the memory 12 and stored in the memory 12.
The timer 11 may be timed after the ignition operation.

Next, when misfire is detected by the thermocouple 8 during the combustion, the combustion control means 10 closes the solenoid valve 2 to stop the gas supply. At this time, the combustion control means 10
Stops the operation of the timer 11 at the same time when the solenoid valve 2 is closed. As a result, the time from the detection of the start of the combustion to the detection of the stop of the combustion by the thermocouple 8 is stored in the memory 12 as the time during which the stove burner 4 is performing the combustion. The original valve is closed by pressing the point / fire extinguishing knob again and releasing the pressing. This operation is based on a known push-push mechanism.

In the gas stove 1 of the present embodiment, next, in order for the user to restart the heating interrupted as described above, the ignition operation is performed again by the point / fire extinguishing knob, and the thermocouple 8 burns. When the combustion control means 10 detects the
The piezoelectric buzzer 1 stores the time stored in No. 2 during the heating by the stove burner 4 until the combustion operation is stopped.
3 is sounded to notify the user.

The notification sound by the piezoelectric buzzer 13 is, for example, when "beep" sounds (70 ms ringing-70 ms stop x 1 time) or when it sounds "peep" (500 ms ringing-
It can be set by changing the timbre, such as 500 ms stop × 1 time). Therefore, for example, if the beep sounds for 1 minute and the beep sounds for 10 minutes while the heating by the stove burner 4 is performed, the combination of the "pi" and the "pee" is generated. As a result, the user can be informed of the time during which the heating by the stove burner 4 was performed before the combustion was stopped.

For example, when the user restarts heating,
When the piezoelectric buzzer 13 beeps (70 ms ringing-70 ms stop x 3 times) when the ignition operation is performed again by the fire extinguishing knob, it means that the stove burner 4 is stopped before the combustion operation is stopped. It indicates that the heating time was 3 minutes,
Ringing (500ms ringing-500ms stop x 2 times, 70
ms ringing-70 ms stop x 1 time), 21 minutes
"Pee, pee, pee" ringing (500ms ringing-500
If stopped for 3 times x 3 times), it indicates 30 minutes.

Therefore, the user stops the combustion during cooking of the cooked object which is baked in about 8 minutes, and thereafter, when the ignition operation is performed again by the point / fire extinguishing knob to restart the heating, the piezoelectric element If the buzzer 13 beeps, it means that this cooked item has already been heated for 3 minutes, and that after heating is resumed, heating should be performed for about 5 minutes or slightly longer. can do. Also, about 60
Combustion stops during cooking of a cooked dish that can be cooked in minutes, and when the ignition operation is performed by the point / fire extinguishing knob to restart heating after that, the piezoelectric buzzer 13 sounds "Pi, Pi, Pi". For example, it can be recognized that the boiled food has already been heated for 30 minutes, and after the heating is restarted, heating may be performed for about 30 minutes or slightly longer.

In the present embodiment, when the user performs an ignition operation with the point / fire extinguishing knob to restart heating, a notification of the time during which the heating by the stove burner 4 is performed before the combustion is stopped. However, the notification may be performed when the user operates an operation switch (not shown) or immediately after the combustion is stopped. If the notification is given immediately after the combustion is stopped, the time measured may not be stored.

Further, as the notification means, instead of the piezoelectric buzzer 13, for example, a visual notification means such as a liquid crystal display device or a light emitting diode may be used.

Also, in the present embodiment, only one stove burner 4 is provided as the heating source, but two or more burners may be provided. In this case, the combustion time of each burner is measured independently and stored in a separate storage means.

Further, in the present embodiment, only the heating time from the start of heating to the stop is shown, but the stop time from the stop of heating to the start of reheating may be notified together with the heating time. . For example, when the notification is made by the piezoelectric buzzer, the heating time and the stop time may be sequentially notified at different cycles, or the time between the notification of the heating time and the notification of the stop time may be set so that the break can be seen. A sound different from the notification may be emitted.

Further, in the present embodiment, the case where the cooking stove is the gas stove 1 is described as an example, but other cooking heating devices such as a grill and an electric heater may be used.
