In the conventional grill, the heating conditions for automatic cooking determined corresponding to the cooking menu are determined as the conditions for continuously burning the heating unit, so the heating amount per unit time for heating the object to be heated is determined. Since the size cannot be reduced sufficiently, there is an inconvenience that a cooking menu for heating the object to be heated to a low temperature cannot be set.

In other words, since the gas combustion type heating unit has a minimum amount of combustion for proper combustion, the heating power of the heating unit cannot be set to a value smaller than the minimum amount of combustion. Therefore, the heating amount per unit time for heating cannot be sufficiently reduced.
As a result, if the heating conditions for automatic cooking determined corresponding to the cooking menu are set to the conditions for continuously burning the heating unit, the cooking menu for heating the object to be heated to a low temperature state cannot be set. becomes.

By the way, as a heating cooking menu for heating the object to be heated to a low temperature state, for example, a cooking container with a lid containing primary fermented bread dough is used as the object to be heated, and the bread dough is fermented (secondary fermentation). , a cooking menu in which meat is heated at a low temperature using a cooking container with a lid containing meat as an object to be heated.
When the bread dough is fermented (secondary fermentation), the primarily fermented bread dough can be maintained in a heated state, for example, at about 35 to 38 ° C. for a set time (for example, about 40 minutes). It is conceivable that when meat is heated at a low temperature, for example, it is considered that the meat is maintained in a heated state of about 60°C.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a grill capable of executing a low-temperature cooking menu for heating food to a low temperature.

The grill of the present invention comprises a grill chamber having a front opening formed in the front portion, a grill door for opening and closing the front opening, and a gas combustion type grill for heating an object to be heated stored inside the grill chamber. A heating unit, an operation control unit that controls the operation of the heating unit, and a cooking menu command unit that commands a cooking menu to be cooked from among a plurality of cooking menus,
When the operation control unit is instructed to start the cooking operation of the cooking menu, the operation control unit controls the operation of the heating unit based on the heating conditions for automatic cooking determined corresponding to the instructed cooking menu Automatic cooking. configured to perform an operation, characterized by:
A door detection unit is provided for detecting a closed state of the grill door,
As the cooking menu, a cooking container with a lid containing an object to be cooked is defined as the object to be heated, and the heating condition for automatic cooking is set to a condition in which the heating unit is burned in a state in which the ignition state and the extinguishing state are repeated. A low-temperature cooking menu was established,
The operation control unit
When the start of the cooking operation of the low-temperature cooking menu is commanded, based on the detection information of the door detection unit, only when the detection information of the door detection unit is the closed state, the extinguishing state is changed to the ignition state. while executing switching to, based on the heating condition for automatic cooking, burning the heating unit in a state where the ignition state and the extinguishing state are repeated, and
During cooking operation, based on the detection information of the door detection unit,
configured to continue the cooking operation of the low-temperature cooking menu when the grill door is open; and
When the heating unit is in the ignition state when the grill door is open, the heating unit continues to burn, and when the grill door is open, the heating unit is in the extinguishing state. In one case, the switching of the heating unit from the extinguishing state to the ignition state is performed only when the grill door is in the closed state based on the detection information of the door detection unit. in the point.

That is, when the grill door is in the closed state, even if the heating unit is switched from the extinguishing state to the igniting state, the user does not feel uncomfortable. A low-temperature heating cooking menu is set as a condition for burning a part in a state of repeating an ignition state and an extinguishing state, and the low-temperature heating cooking menu for heating an object to be heated in a low temperature state can be executed.
In other words, although the object to be heated is heated when the heating unit is ignited, when the heating unit is extinguished, the object to be heated is heated by the amount of heat stored in the grill chamber. can be heated properly.

Moreover, since the object to be heated is a cooking container with a lid containing the object to be cooked, heat from the flame of the heating unit does not directly act on the object to be cooked. Can be heated at low temperature.
Incidentally, in the extinguished state of the heating unit, the food to be cooked is heated while also utilizing the amount of heat stored in the cooking container that is heated in the burning state of the heating unit.

Further, switching from the extinguishing state of the heating unit to the igniting state is executed only when the grill door is closed based on the detection information of the door detection unit, in other words, the extinguishing state of the heating unit. To appropriately avoid giving a feeling of discomfort to a user by not executing switching from a lighting state to an ignition state when a grill door is in an open state.

In short, according to the characteristic configuration of the grill of the present invention, it is possible to execute a low-temperature heating cooking menu for heating the object to be heated to a low-temperature state.

A further characteristic configuration of the grill of the present invention is that the heating unit is configured to heat the bottom and top of the object to be heated,
As the low-temperature heating cooking menu, a bread dough fermentation mode for fermenting the bread dough by heating the cooking container containing bread dough as the object to be heated is set, and as a heating condition for automatic cooking for the bread dough fermentation mode, the cooking container is A heating condition for fermenting bread dough for heating the temperature of the stored bread dough to a set temperature for fermentation is set to a condition for burning the heating unit in a state where the ignition state and the extinguishing state are repeated,
The operation control unit is configured to execute the automatic cooking operation based on the heating conditions for bread dough fermentation when the bread dough fermentation mode is commanded.

That is, by storing bread dough in a cooking container with a lid and commanding a bread dough fermentation mode for fermenting bread dough as a cooking menu, the operation control unit changes the temperature of the bread dough stored in the cooking container to the set temperature for fermentation. An automatic cooking operation is performed to control the operation of the heating unit based on the heating conditions for fermenting the bread dough to be heated, and the bread dough is fermented.
Since the heating conditions for bread dough fermentation are determined to burn the heating part in a state where the ignition state and the extinguishing state are repeated, the bread dough stored in the cooking container can be appropriately heated to the set temperature for fermentation. can be done.

By the way, when the bread dough that has undergone primary fermentation is subjected to secondary fermentation, the bread dough stored in the cooking container is heated to, for example, about 35 to 38 ° C. as the preset temperature for fermentation, and when the bread dough is subjected to primary fermentation is to heat the bread dough housed in the cooking container to, for example, 27 to 30° C. as the preset temperature for fermentation.

In short, according to a further characteristic configuration of the grill of the present invention, dough can be fermented.

A further characteristic configuration of the grill of the present invention is that a container temperature detection unit that detects the temperature of the bottom of the cooking container is provided, and the heating conditions for fermenting the bread dough are such that at the start of cooking, the temperature of the bottom reaches a set target temperature. , the heating unit is heated under an initial heating condition in which the heating operation is performed with an initial heating power, and thereafter, the heating unit is continuously heated until the set target temperature is reached each time the bottom temperature reaches the set lower limit temperature. The condition is that the heating operation is performed under the continuous heating condition that the heating operation is performed by force, and the heating operation is stopped after the set cooking time elapses.

That is, based on the information detected by the container temperature detection unit that detects the bottom temperature of the cooking container, when cooking starts or when the bottom temperature reaches the set lower limit temperature during cooking, the bottom temperature of the cooking container is set to the set target temperature. Therefore, the bottom temperature of the cooking container, which has a high correlation with the temperature of the dough stored in the cooking container, is maintained at a temperature close to the set target temperature, and the temperature of the dough stored in the cooking container is increased. It can be properly heated to the set temperature for fermentation.

In short, according to a further characteristic configuration of the grill of the present invention, the temperature of the bread dough stored in the cooking container is appropriately heated to the set fermentation temperature based on the bottom temperature of the cooking container detected by the container temperature detecting section. be able to.

A further characteristic configuration of the grill of the present invention is that a container temperature detection unit that detects the temperature of the bottom of the cooking container is provided, and the heating conditions for fermenting the bread dough are set at the start of cooking until the set initial heating time elapses. Heating is performed under the initial heating condition in which the part is heated with the initial heating power, and after that, the heating part is heated at the set continuous heating power until the set continuous elapsed time elapses each time the bottom temperature reaches the set lower limit temperature. The heating operation is continued under the continuous heating condition in which the heating operation is performed at the same time, and the heating operation is stopped when the set cooking time elapses.

That is, at the start of cooking, the heating unit is operated with the initial heating power until the set initial heating time elapses, and thereafter, each time the bottom temperature detected by the container temperature detection unit reaches the set lower limit temperature, the set continuation progresses. By heating the heating unit with the set continuous heating power until the time elapses, the temperature of the bread dough stored in the cooking container is heated to the set temperature for fermentation.

At the start of cooking or when the bottom temperature reaches the set lower limit temperature, the heating time by the heating part is controlled and heated, so the detected temperature of the container temperature detection part is the heating of the gas combustion type heating part. Even when the operation becomes unstable, the temperature of the bread dough stored in the cooking container can be easily heated to the set temperature for fermentation.
In other words, when the gas-combustion type heating unit that heats the bottom of the cooking container heats up, the temperature detected by the container temperature detecting unit becomes unstable because the container temperature detecting unit is heated by the heating unit that performs heating operation. Although there is a risk, when the bottom temperature reaches the set lower limit temperature at the start of cooking or during cooking, the temperature detected by the container temperature detection unit becomes unstable by controlling the heating time of the heating unit and heating. Even so, the temperature of the bread dough stored in the cooking container can be easily heated to the preset temperature for fermentation.

In short, according to the further characteristic configuration of the grill of the present invention, even if the temperature detected by the container temperature detector becomes unstable, it is easy to appropriately heat the temperature of the bread dough stored in the cooking container to the set temperature for fermentation.

A further characteristic configuration of the grill of the present invention is provided with an internal temperature detection unit for detecting the internal temperature of the grill chamber,
When the bottom temperature exceeds the set upper limit temperature on the bottom side, and when the internal temperature exceeds the set upper limit temperature on the inner side, the automatic cooking operation in the bread dough fermentation mode is configured not to run

That is, when the bottom temperature of the cooking container exceeds the bottom-side set upper limit temperature, and when the internal temperature of the grill chamber exceeds the inner set upper limit temperature, the operation control unit selects the bread dough fermentation mode. Since the automatic cooking operation is not executed, it is possible to avoid damaging the bread dough by heating the dough stored in the cooking container to a temperature higher than the set temperature for fermentation to kill the yeast.

In other words, for example, the fermentation set temperature for fermentation (secondary fermentation) of bread dough that has undergone primary fermentation is as low as 35 to 38 ° C., but the cooking container is used for other cooking menus. There is a risk that the set upper limit temperature will exceed the set upper limit temperature on the bottom side (for example, 40°C). ℃), and in such a case, the bread dough stored in the cooking container cannot be properly fermented (secondary fermentation). Damage to the bread dough is suppressed.

In short, according to the further characteristic configuration of the grill of the present invention, damage to the bread dough can be suppressed.

A further characteristic configuration of the grill of the present invention is that the cooking menu includes a bread dough fermentation baking mode for fermenting bread dough and baking the bread dough, and the heating conditions for automatic cooking for the bread dough fermentation baking mode are: Heating conditions for fermenting and baking bread dough, which include heating conditions for baking bread dough for baking bread dough subsequent to the heating conditions for bread dough fermentation, are determined,
The operation control unit is configured to execute the automatic cooking operation based on the heating conditions for fermentation and baking of the bread dough when the bread dough fermentation and baking mode is instructed.
In this bread dough fermentation baking mode, bread dough means primary fermented bread dough, and fermentation of bread dough means secondary fermentation of primary fermented bread dough.

That is, by putting the primarily fermented bread dough into a cooking container and commanding the bread dough fermentation baking mode, the bread dough can be fermented (secondary fermentation) and baked.
In this way, the fermentation (secondary fermentation) and baking of the bread dough can be continuously performed, so that the bread can be cooked (made) satisfactorily.

In short, according to the further characteristic configuration of the grill of the present invention, it is possible to satisfactorily cook (make) bread while continuously performing fermentation (secondary fermentation) and baking of bread dough.

A further characteristic configuration of the grill of the present invention is that, when the operation control unit executes the automatic cooking operation based on the heating conditions for fermenting and baking bread dough, the heating unit is switched from the extinguishing state to the ignition state. The switching is performed only when the grill door is in the closed state based on the detection information of the door detection section.

That is, in the bread dough fermentation baking mode in which the bread dough is fermented and the bread dough is baked, when the heating unit is operated under the heating conditions for baking the bread dough subsequent to the heating conditions for fermenting the bread dough, the heating unit in the extinguished state is switched to the lighting state. In some cases, when switching the heating unit from the extinguishing state to the ignition state in this way, if the grill door is open, the heating unit cannot be switched from the extinguishing state to the ignition state, and the grill door is closed. At some point the heater will switch from extinguished to ignited.

In short, according to the grill of the present invention, when the heating operation of the heating unit is started under the heating conditions for baking the bread dough subsequent to the heating conditions for fermenting the bread dough, when the grill door is in the open state, the heating unit is turned off from the extinguishing state. By not switching to the ignition state, it is possible to avoid giving a sense of discomfort to the user.

That is, until the bottom temperature Ts of the cooking pot 9C reaches the set target temperature (for example, 38° C.), the grill burner 7 is heated under the initial heating condition of heating with the initial heating power.
Although not described, when the grill burner 7 is heated with the initial heating power, it is determined whether or not the grill door 8 is closed based on the detection information of the storage detector N, and the grill is opened. Only when the door 8 is closed, the grill burner 7 is switched from the extinguishing state to the igniting state.

Incidentally, when executing this initial heating treatment, the heating power of the grill burner 7 is set to the heating power set based on the rehabilitation treatment.
Also, when the cooking timer starts to count, the display control unit BD displays the "cooking screen" (FIG. 18), so that the user can recognize that the automatic cooking operation is being executed. can be done.

After performing the initial heating process in #12, or when it is determined to be residual heat cooking in #11, the fermentation time, that is, the set cooking in the heating conditions for fermenting the bread dough is determined based on the time measured by the cooking timer. It is determined whether or not time (for example, 40 minutes) has passed (#13).

When it is determined in #13 that the set cooking time (for example, 40 minutes) has not elapsed, it is subsequently determined whether or not heat cooking is set (#14).
If cooking with heat is set, it is determined whether or not the grill burner 7 is burning (#15). (#16).
Then, when the bottom temperature Ts is equal to or lower than the set lower limit temperature (for example, 35° C.), subsequently, it is determined whether or not the grill door 8 is closed based on the detection information of the storage detection unit N ( #17) When the grill door 8 is in the closed state, the heating process for heating the grill burner 7 with the set continuous heating power is started (#18).

After the heat treatment of #18 is started and when it is determined that the grill burner 7 is burning in #15, it is checked whether the bottom temperature Ts is equal to or higher than the set target temperature (for example, 38°C). If it is determined (#19) and the bottom temperature Ts is equal to or higher than the set target temperature (for example, 38° C.), extinguishing processing for extinguishing the grill burner 7 is executed (#20).

If it is determined in #14 that cooking is not set, and if it is determined in #16 that the bottom temperature Ts is not lower than the set lower limit temperature (for example, 35°C), the grill door 8 is closed in #17. If it is determined that it is not, and if it is determined in #19 that the bottom temperature Ts is not equal to or higher than the set target temperature (for example, 38° C.), the process proceeds to #13, and similarly, #20. Also when the fire extinguishing process of No. 1 is executed, the process of #13 is performed.

If it is determined in #13 that the fermentation time (the set cooking time (for example, 40 minutes) in the heating conditions for fermentation of bread dough) has passed, it is determined whether or not the grill burner 7 is burning ( #21).
When it is determined that combustion is not in progress, it is determined whether or not the grill door 8 is closed based on the detection information from the storage detector N (#22). , and the heating power of the lower burner 7S and the heating power of the upper burner 7U are set to "strong" and the grill burner 7 is burned (#23).
Incidentally, when it is determined in #20 that the grill door 8 is not in the closed state, the grill door 8 waits until the grill door 8 is closed, and when the grill door 8 is in the closed state, the heating process for baking is executed. (#21).

Further, when it is determined in #21 that the grill burner 7 is burning, the process proceeds to #23 for the baking heat treatment, and the heating power of the lower burner 7S and the heating power of the upper burner 7U are set to "strong". Then, the combustion of the grill burner 7 is continued.

After starting the heat treatment for firing in #23, it is determined whether the firing time (e.g., 15 minutes) has elapsed (#24), and until the firing time (e.g., 15 minutes) has elapsed , and #23, and when the baking time (for example, 15 minutes) has elapsed, the fire extinguishing process for extinguishing the grill burner 7 is executed (#25).

After executing the fire extinguishing process of #25, it is determined whether or not the baking preheat time (for example, 2 minutes) has passed (#26), and when the baking preheat time (for example, 2 minutes) has passed, bread dough is fermented and baked End the automatic cooking operation of the mode (“fermentation (secondary) → baking”).
When the automatic cooking operation in the bread dough fermentation baking mode (“fermentation (secondary)→baking”) ends, the display control unit BD displays the “cooking end screen” (FIG. 19) as described above. Therefore, the user can recognize the end of the automatic cooking operation.

By the way, the control operation of the bread dough fermentation mode (“fermentation (secondary)”) is the control operation corresponding to #1 to #20 in the bread dough fermentation baking mode (“fermentation (secondary) → baking”) described above. In order to avoid overlapping explanations, the explanation of the control operation of the bread dough fermentation mode (“fermentation (secondary)”) is omitted.
In addition, the control operation of the baking mode is to perform the control operation corresponding to #22 to #26 in the above-described bread dough fermentation baking mode (“fermentation (secondary) → baking”). , the description of the control operation of the baking mode is omitted.
