The gas grill 83 of the gas stove 80 with a grill includes an upper temperature detection unit 53 (53b) for determining heat capacity and a lower temperature detection unit as a temperature detection unit (temperature sensor) 53 for detecting the temperature in the grill chamber 1. (Lower center temperature detection unit 53 (53a) for temperature gradient detection for detecting the temperature rise gradient, lower left temperature detection unit (left temperature detection unit) 53 (53L) for temperature gradient detection, and lower right temperature A detector (right temperature detector) 53 (53R) is provided.
It should be noted that the position where the above-described temperature detection unit 53 (53b) is disposed is the time from the start of heating until it rises to a predetermined temperature (setting determination temperature described later), that is, the elapsed time for heat capacity determination. The positions are different depending on the magnitude of the heat load of the food 95 to be cooked.

Note that the temperature detection unit 53 (53b) measures the temperature rise gradient that changes according to the difference in the mass of the food 95 on the food support 3 in the initial stage of the cooking process after the start of heating by the grill burner. Then, the heat capacity of the object 95 to be cooked is detected, and as described later, the control unit 86 functions to obtain the remaining time until cooking is completed.

In addition, the temperature detection units 53 (53a, 53L, 53R) measure the temperature rise that changes when the radiant heat from the flame of the grill burner is blocked by the object 95 to be cooked in the early stage of the cooking process after the heating by the grill burner is started. By measuring the gradient, the placement position, size, shape, etc. of the object 95 to be cooked can be recognized.

Then, the control unit 86 performs determination information calculation processing for obtaining the temperature rise gradient based on the detection information of the temperature detection unit 53 (53b), and based on the temperature rise gradient information obtained by the determination information calculation processing. Then, a remaining heating time setting process for setting a remaining heating time from the execution of the determination information calculation process to the end of heating the food 95 is executed.

In this gas stove with grill 80, the above-described temperature detection unit 53 (53b) detects the heat capacity of the object 95 to be cooked after starting heating by the grill burner, which changes due to the difference in the heat capacity of the object 95 to be cooked.

Then, based on the result, the control unit 86 performs determination information calculation processing for obtaining the heat capacity determination elapsed time, and when setting the remaining heating time from the temperature rise gradient, the obtained heat capacity determination elapsed time information Based on, it is configured to perform correction so as to obtain an appropriate remaining heating time.

[First Characteristic Configuration]
A gas grill 83 constituting the gas stove 80 with grill according to the present embodiment has a first characteristic configuration as described below.
That is, the gas grill 83 that constitutes the gas stove 80 with a grill according to this embodiment is heated by the grill burners 41 and 42, and the control unit 86 is provided with an abnormal overheating prevention temperature setting unit (not shown) that sets an abnormal overheating prevention temperature as a threshold for the temperature detected by the temperature detection unit 53 (53b) for forcibly extinguishing the grill burners 41 and 42 .

Further, the gas grill 83 is configured such that the control unit 86 extinguishes the grill burners 41 and 42 when the cooking of the food 95 is completed when automatic cooking is performed.

In the gas grill 83 provided in the gas stove 80 with a grill, the temperature inside the grill chamber 1 (for example, the temperature detected by the temperature detection unit 53 (53b)) when cooking is completed is a first temperature higher than the second temperature (for example, 180° C.) below. The first cooking time (for example, 600° C.) from the start of heating by the grill burners 41 and 42 to the completion of cooking of the first food (for example, one whole mackerel) serving as the food 95 to be cooked (for example, 210° C.) is the first cooking time (for example, 600 seconds), and when the cooking is completed, the temperature inside the grill chamber 1 (for example, the temperature detected by the temperature detection unit 53 (53b)) is a second temperature (for example, 180°C) lower than the first temperature (for example, 210°C). When the second cooking time ( e.g., 840 seconds ) is the heating time from the start of heating by the grill burners 41 and 42 to the completion of cooking of the second food (e.g., 4 round horse mackerel) as the food 95 to be cooked. , an abnormal overheat prevention temperature setting unit (not shown) sets a first temperature (eg, 210° C.), a first cooking time (eg, 600 seconds), a second temperature (eg, 180° C.), and a second cooking time (eg, 840 seconds), a change setting unit (not shown) is provided for changing and setting the abnormal overheating prevention temperature from the start of heating by the grill burners 41 and 42 to the completion of cooking.

FIG. 9 shows an example of the abnormal overheating prevention temperature of the embodiment set as described above.

The gas grill 83 according to the present embodiment is configured as described above, and the abnormal overheating prevention temperature setting unit (not shown) sets the first temperature, first cooking time, second temperature, and second cooking time. Since the change setting part is provided for changing and setting the abnormal overheating prevention temperature from the start of heating by the grill burners 41 and 42 to the completion of cooking based on the above, it is possible to select the food with a high internal temperature at the completion of cooking. Even when cooking, even when cooking food with a low internal temperature at the time of completion of cooking, a so-called premature burnout state occurs in which the gas burner extinguishes before cooking is completed. To suppress and prevent the occurrence of a so-called delayed shutdown state in which the burning of a gas burner does not stop until unacceptable scorching occurs in the food (the gas burner extinguishes after the cooking food is severely scorched).

In the gas grill 83, the second cooking time (for example, 840 seconds) is longer than the first cooking time (for example, 600 seconds). During the period from the start of heating by 41 and 42 to the completion of cooking, the abnormal overheating prevention temperature is a first correction temperature (for example, 240° C.) set higher than the first temperature (for example, 210° C.) by a first predetermined temperature (for example, 30° C.). ° C.) to a second correction temperature (eg, 195° C.) set higher than the second temperature (eg, 180° C.) by a second predetermined temperature (eg, 15° C.).

On the other hand, for example, when the temperature detection unit 53 (53b) is arranged at a position different from that of the present embodiment, and the first cooking time is longer than the second cooking time, abnormal overheating prevention is performed. A temperature setting unit (not shown) adds a second predetermined temperature (15° C.) to the second temperature (180° C.) as the abnormal overheating prevention temperature from the start of heating by the grill burners 41 and 42 to the completion of cooking. It is also possible to change and set the second corrected temperature (195°C) to the first corrected temperature (240°C) obtained by adding the first predetermined temperature (30°C) to the first temperature (210°C). be.

With this configuration, it is possible to suppress or prevent the occurrence of a so-called early-off state in which the gas burner extinguishes before cooking is completed, and also to prevent the occurrence of a so-called late-off state in which the gas burner extinguishes the gas burner after the food is severely scorched. It is possible to rationally configure the gas grill 83 capable of suppressing and preventing the occurrence of

In addition, in the gas grill 83 according to the present embodiment, the second cooking time (for example, 840 seconds) is longer than the first cooking time (for example, 600 seconds), and the abnormal overheating prevention temperature setting unit (not shown) is set to the grill burners 41 and 42. From the first correction temperature (e.g., 240°C) that is set to a first predetermined temperature (e.g., 30°C) higher than the first temperature (e.g., 210°C) from the start of heating to the end of cooking by It is configured to gradually drop (gradually decrease) to a second correction temperature (eg, 195° C.) set to a second predetermined temperature (eg, 15° C.) higher than the second temperature (eg, 180° C.) (see FIG. 9). ).

On the other hand, when the first cooking time is longer than the second cooking time, such as when the temperature detection unit 53 (53b) is arranged at a position different from that of the present embodiment, abnormal overheating A prevention temperature setting unit (not shown) changes the abnormal overheat prevention temperature from the second temperature (180° C.) to the second predetermined temperature (15° C.) from the start of heating by the grill burners 41 and 42 to the completion of cooking. From the added second correction temperature (195° C.), the temperature is gradually increased (gradually increased) to the first correction temperature (240° C.) obtained by adding the first predetermined temperature (30° C.) to the first temperature (210° C.). It is also possible to configure

Thus, the abnormal overheating prevention temperature is changed from the first correction temperature (eg, 240° C.) set higher than the first temperature (eg, 210° C.) by a first predetermined temperature (eg, 30° C.) to the second temperature (eg, 180° C.). ) to a second correction temperature (e.g. 195°C) set higher than a second predetermined temperature (e.g. 15°C), or (if the first cooking time is longer than the second cooking time) prevention of abnormal overheating When the temperature is configured to gradually increase to a first correction temperature (eg, 240° C.) set to a second predetermined temperature (eg, 30° C.) higher than the second temperature (210° C.), the abnormal overheating prevention temperature is finely set. Thus, it is possible to realize a gas grill capable of more accurately suppressing and preventing the occurrence of an early cut-off state or a late cut-off state.

In the present embodiment, as shown in FIG. 9, the abnormal overheating prevention temperature is set to a first correction temperature (eg, 240° C.) higher than the first temperature (eg, 210° C.) by a first predetermined temperature (eg, 30° C.). to the second correction temperature (eg, 195° C.) which is set higher than the second temperature (eg, 180° C.) by a second predetermined temperature (eg, 15° C.). 2, the abnormal overheat prevention temperature may be changed stepwise from the first correction temperature (eg, 240° C.) to the second correction temperature (eg, 195° C.).

That is, the abnormal overheating prevention temperature is changed from the first temperature (eg, 210° C.) to the first predetermined temperature (eg, 30° C.) between the first cooking time (eg, 600 seconds) and the second cooking time (eg, 840 seconds). Gradually from a first corrected temperature set higher (eg 240°C) to a second corrected temperature (eg 195°C) set higher by a second predetermined temperature (eg 15°C) than the second temperature (eg 180°C) Instead, as shown in FIG. 10, it may be changed stepwise.

It is possible to provide a gas grill capable of suppressing and preventing the occurrence of early and late shutdown even when the power is changed stepwise in this way.

In addition, in the gas grill of the present invention, the abnormal overheating prevention temperature immediately after the start of heating by the grill burners 41 and 42 is determined by the temperature inside the grill chamber 1 (for example, the temperature detector 53 (53b)) immediately after the start of heating by the grill burners 41 and 42. detection temperature). In this case, regardless of the ambient temperature of the gas grill 83 provided in the gas stove with grill 80, a so-called premature burnout state occurs in which the gas burner extinguishes before the cooking is completed, and the gas burner shuts down after the food to be cooked is severely scorched. It is possible to provide a gas grill capable of more accurately suppressing and preventing the so-called slow-off state of fire extinguishing.

By the way, when using the gas grill 83 according to the present embodiment to cook two open pieces of saury (third cooking object) as the cooking object 95, the timer setting input unit 93b of the grill-side operation panel 93 is used to start cooking. The change in temperature detected by the temperature detector 53 (53b) when cooking is performed with the grill cooking timer set to 900 seconds (15 minutes) as the heating time until completion is gradually increased to the abnormal overheating prevention temperature. In this case, as shown in FIG. 9, abnormal overheating (a state in which the temperature detected by the temperature detection unit 53 (53b) exceeds the abnormal heating prevention temperature) Upon detection, the control unit 86 forcibly extinguishes the grill burners 41 and 42, and does not stop the combustion of the gas burner until the food is unacceptably scorched. extinguishing), that is, the occurrence of a so-called delayed shutdown state is suppressed or prevented.

Also, when using the gas grill of this embodiment to cook two slices of saury (the third food to be cooked), the timer setting input unit 93b of the grill-side operation panel 93 is used to set the cooking timer for grilling to 900 seconds. (15 minutes), the transition of the temperature detected by the temperature detection unit 53 (53b) is also shown in FIG. Also, as shown in FIG. 10, abnormal overheating (a state in which the temperature detected by the temperature detection unit 53 (53b) exceeds the abnormal heating prevention temperature) is detected, and the control unit 86 forcibly extinguishes the grill burners 41 and 42. This suppresses and prevents the occurrence of a so-called slow-off state in which the gas burner does not stop burning until the food is unacceptably scorched (the gas burner extinguishes after the food is severely scorched). .

With this configuration, the user can surely recognize that the cooking is finished when the cooking is finished, and that the cooking is being performed when the cooking is being performed. It is possible to provide a gas grill with good usability.

As described above, the gas grill 83 according to the present embodiment is determined by the change in temperature detected by the temperature detection unit 53 (53b) after the control unit 86 starts heating by the grill burners 41 and 42 by the ignition/extinguishing switch 93a. The setting value of the cooking timer section is automatically set according to the heat capacity of the food to be cooked. With this configuration, the value of the cooking timer (remaining heating time) is automatically set by the control unit 86, so it is possible to provide a gas grill that is easy to use.

Further, the gas grill 83 according to the present embodiment includes a timer switch (timer setting input section) 93b for setting the set value of the cooking timer section for grilling. It is configured so that the set value of the cooking timer section can be set, that is, the timer can be set as desired by the user. By configuring in this way, it is possible to provide a gas grill that is easy to use and that allows the setting value of the cooking timer section to be set according to the preference of the user.

Further, in the gas grill 83 according to the present embodiment, after the grill burners 41 and 42 are extinguished in the event of abnormal overheating, the temperature detected by the temperature detection unit 53 (53b) reaches the second If the temperature does not rise above the threshold temperature (error notification temperature 2), the control unit 86 sets the remaining time until cooking is completed to be shorter than the value at the time of forced extinguishing of the grill burners 41 and 42 during abnormal overheating (for example, After setting 80 to 90% (that is, minus 10 to 20%) of the remaining time until the completion of cooking at the time of forced extinguishing of the grill burners 41 and 42 at the time of abnormal overheating, cooking is continued in the form of continuing countdown. is configured as

When the grill burners 41 and 42 are forcibly extinguished due to abnormal overheating, the temperature inside the grill chamber 1 is higher than that during normal cooking. After the grill burners 41 and 42 are set to be shorter than the value at the time when the grill burners 41 and 42 are forcibly extinguished, the cooking is continued in the form of continuing the countdown, thereby making it possible to perform proper cooking.

In addition, in the gas grill 83 according to the present embodiment, after the grill burners 41 and 42 are extinguished in the event of abnormal overheating, the temperature detected by the temperature detection unit 53 (53b) drops below a predetermined first threshold temperature (error notification temperature 1).

When the temperature detected by the temperature detection unit 53 (53b) drops below a predetermined first threshold temperature (error notification temperature 1), the control unit 86 indicates that cooking is completed when the grill burners 41 and 42 are forcibly extinguished during abnormal overheating. It is configured to be set as short as 90% (minus 10%) of the remaining time until the hour.

By configuring in this way, it becomes possible to perform proper cooking. That is, when the temperature detected by the temperature detection unit 53 (53b) drops below a predetermined first threshold temperature (error notification temperature 1) after extinguishing the grill burners 41 and 42 during abnormal overheating, the temperature detection unit 53 (53b ) does not fall below the predetermined first threshold temperature (error notification temperature 1). By setting the remaining time until cooking is completed longer than when the detected temperature does not drop below a predetermined first threshold temperature (error notification temperature 1), cooking can be properly performed.

Further, in the gas grill 83 according to the present embodiment, the first threshold temperature (error notification temperature 1) and the second threshold temperature (error notification temperature 2) are the abnormal overheating temperature at the time when the grill burners 41 and 42 are extinguished at the time of abnormal overheating. It is set based on the prevention temperature.

More specifically, the first threshold temperature (error notification temperature 1) is set to a temperature β (for example, 30° C.) lower than the abnormal overheating prevention temperature at the time when the grill burners 41 and 42 are extinguished in the event of abnormal overheating. The temperature (error notification temperature 2) is set to a temperature α (for example, 10° C.) higher than the abnormal overheating prevention temperature when the grill burners 41 and 42 are extinguished in the event of abnormal overheating (see FIG. 11).
