On the other hand, in this type of gas stove, when cooking a tempura dish or a fried food using a burner having a standard burning capacity, the oil temperature is set to a desired temperature (for example, 1).
It is also known to have a temperature control function of automatically adjusting the heating power of the burner so as to maintain it at 60 ° C. In the gas stove having the temperature control function as described above, the fuel supply passage to the burner is, for example, on the downstream side of the thermal power adjustment valve, a main fuel supply passage provided with an opening / closing solenoid valve and a bypass passage bypassing the opening / closing solenoid valve. Branched to. In addition, a temperature sensor that comes into contact with the pan on the burner is provided at the center of the burner. Then, the temperature of the oil in the pan is detected by the temperature sensor through the pan, and the open / close solenoid valve is opened / closed intermittently so that the detected temperature is maintained at a desired temperature. Is intermittently switched to strong or weak.
Specifically, when the detected temperature becomes higher than the desired temperature to some extent, the opening / closing solenoid valve is closed to close the main fuel supply passage, and fuel is supplied to the burner through the bypass passage, thereby weakening the heating power. When the detected temperature becomes lower than the desired temperature to some extent, the opening / closing solenoid valve is opened to open the main fuel supply passage, and fuel is supplied to the burner through both the main fuel supply passage and the bypass passage. , Increase the firepower. In addition, the bypass passage has, for example, an amount substantially equal to the fuel supplied to the burner in a state where the thermal power control valve is operated to the minimum thermal power side during the non-temperature control operation (the open / close solenoid valve is held open). The passage area and the like are set so that the fuel is supplied to the burner through the bypass passage when the opening / closing solenoid valve is closed during the temperature control operation.

However, the temperature control function is, for example, 3500 to
It has been found by the study of the present inventors that the following inconveniences occur when added to a burner having a high combustion capacity of 5000 kcal / h (hereinafter referred to as a high calorie burner).

That is, for example, the heat power adjustment range of the high power calorie burner is 4600 to 400 k.
Cal / h, if the temperature control operation is performed in a state in which the thermal power control valve is operated to the maximum thermal power side, the thermal power of the burner during the high heat operation in which the opening / closing solenoid valve is opened is 460.
It becomes about 0 kcal / h, and the thermal power at the time of low heat operation in which the open / close solenoid valve is closed is about 400 kcal / h.

Therefore, when the heat of the burner is switched from the high heat to the low heat during the temperature control operation, the fuel supply amount to the burner is drastically greatly reduced, and the burner is liable to misfire. Also, when the burner has a high heat during temperature control operation, the large heat causes the temperature of the food in the pan to rise rapidly, so opening and closing when the temperature rises to a certain level above the desired temperature Even if the electromagnetic valve is closed and the burner heat is switched to low heat, the temperature does not immediately drop and so-called overshoot is likely to occur. For this reason,
There is an inconvenience that the temperature of the cooked food tends to be excessively high with respect to the desired temperature.

Specifically, for example, when a tempura dish is set, the temperature control unit 11 detects that the temperature detected by the temperature sensor 8 for the food A is 1 after the combustion operation of the burner 1 is started.
Until the temperature reaches 60 + α ° C (where α is a predetermined value, for example, 3 ° C), the solenoid valve 5 is kept open to allow the burner 1 to supply the fuel gas through the main fuel supply passage 3a and the bypass passage 3b. The burning power of burner 1 is set to high and the detected temperature is 160
When the temperature reaches + α ° C, the solenoid valve 5 is closed to close the main fuel supply passage 3a, and the burner 1 is supplied with fuel gas only through the bypass passage 3b, so that the burner 1 has a low heat. Then, due to this low heat operation, the detected temperature is 16
When the temperature drops to 0-α ° C, the solenoid valve 5 is opened again to make the heating power of the burner 1 strong, and thereafter the opening / closing control of the solenoid valve 5 is repeated to switch the heating power of the burner 1 to strong or weak. Thus, the temperature control for maintaining the temperature of the cooked food A at a substantially required temperature (160 ° C) is performed.

The heating power setting operator 6 is set to a medium heating power range below the high heating power range of the burner 1 (for example, 3000 kcal /
When, for example, a tempura dish is set by the operating device 9 and the combustion operation of the burner 1 is started in the state of being operated in h), the temperature control unit 11 causes the thermal power of the burner 1 to reach the temperature detected by the temperature sensor 8 as described above. In response to this, the solenoid valve 5 is controlled to be opened and closed, and the heating power of the burner 1 is appropriately switched between strong and weak. As a result, as shown in FIG. 2, temperature control is performed so that the temperature of the cooked food A is maintained at a substantially predetermined temperature (160 ° C.).

At this time, in the high-fire operation state of the burner 1 (open state of the solenoid valve 5), the amount of fuel gas corresponding to the heat power (<3500 kcal / h) set by the heat power setting operator 6 is the main fuel. The burner 1 is supplied to the burner 1 via the supply passage 3a and the bypass passage 3b, and the burner 1 with its thermal power (high heat)
Combustion operation is performed. Further, when the burner 1 is in a low heat operation state (the solenoid valve 5 is closed), the minimum heat power of the burner 1 (4
A fuel gas equivalent to a thermal power of about 100 kcal / h) is supplied to the burner 1 via only the bypass passage 3b, and the combustion operation of the burner 1 is performed with the thermal power (low heat).

In this case, since the burning power (<3500 kcal / h) of the burner 1 at the time of high-fire operation is not excessively high, the amount of decrease in the fuel gas at the time of switching from the high-fire operation to the low-fire operation is relatively small. , When switching
Burner 1 will not misfire. Also, the thermal power of the burner 1 during high heat operation (<3500 kcal / h)
Since the temperature is not too high, the temperature of the cooked food A at this time does not rise excessively rapidly, and therefore, when switching from high heat to low heat (when the detected temperature reaches 160 + α ° C) In addition, the temperature rise (overshoot) of the inertial food A is suppressed, and therefore, the excessive temperature rise of the food A is suppressed and the temperature control is accurately controlled to the desired temperature (160 ° C). It can be carried out. Further, since the open / close solenoid valve 5 is closed and no misfire occurs when switching from the high heat operation to the low heat operation, the heat power of the low heat operation is set to a sufficiently small heat power (about 400 kcal / h) as in the present embodiment. Therefore, even when the amount of the cooked food A is small, the temperature of the cooked food A increased during the high heat operation is decreased during the low heat operation so that the temperature of the cooked food A is almost required. It can be maintained at a temperature (160 ° C).

On the other hand, the heating power setting operator 6 is attached to the burner 1.
When the burning operation of the burner 1 is started by setting, for example, a tempura dish with the operation device 9 in the state of being operated in the high heat power range (≧ 3500 kcal / h), the micro switch 7 is in the ON state, A temperature control prohibition command unit 12 gives a temperature control control prohibition command to the temperature control unit 11.
Therefore, the temperature control unit 11 holds the solenoid valve 5 in the open state without controlling the opening and closing as described above. Therefore, the switching of the heating power of the burner 1 is not performed. In this case, since the thermal power of the burner 1 is high (≧ 3500 kcal / h) when the electromagnetic valve 5 is open, the electromagnetic valve 5 is temporarily closed to reduce the thermal power of the burner 1 to low heat (about 400 kcal / h).
If it changes to h), there is a risk that the burner 1 will misfire due to a sudden decrease in the amount of fuel gas supplied to the burner 1, but such inconvenience will occur because the burning power of the burner 1 is not switched. There is no such thing.

On the other hand, the heating power setting operator 6 is attached to the burner 1
When the burning operation of the burner 1 is started by setting, for example, a tempura dish with the operation device 9 in the state of being operated in the high heat power range (≧ 3500 kcal / h), the micro switch 7 is in the ON state, The operation stop command unit 13 gives an operation stop command to the burner 1 to the operation control unit 14. Therefore, the operation control unit 14 closes the safety valve SV, and the combustion operation of the burner 1 is stopped. Therefore, it is possible to avoid a situation in which the temperature control operation is performed in a state where misfire of the burner 1 and an excessive rise in the temperature of the cook A are likely to occur.
Further, by stopping the combustion operation, it is possible to avoid a situation in which the combustion operation of the burner 1 is continuously performed while the user thinks that the proper temperature control operation will be performed.

Further, when the combustion operation of the burner 1 is stopped in this way, the annunciator 10 gives an alarm by lighting or blinking a lamp or a buzzer according to an instruction from the operation stop command section 13. Therefore, the user can recognize that the combustion operation is stopped because the heat power of the burner 1 set by the heat power setting operator 6 is too strong. Then, by the recognition, the user weakens the set thermal power of the burner 1 by the thermal power setting operator 6 (sets the thermal power of 3500 kcal / h or less),
When the combustion operation of the burner 1 is restarted, the temperature control operation can be performed without any trouble.
