Description

The present invention provides a bunsen combustion type lower burner that is installed at the bottom of a grill cabinet and heats the cooking vessel stored in the grill cabinet from below, and the cooking vessel that is installed on the ceiling of the grill cabinet. A bunsen combustion type upper burner that heats from above is provided,
The present invention relates to a grill provided with a temperature detection sensor for detecting the temperature of the cooking vessel and an operation control unit for controlling the combustion operation of the lower burner and the upper burner based on detection information of the temperature detection sensor.

  Such a grill is mainly mounted on a gas stove, and as a conventional example of such a grill, a structure in which a dedicated pan for a Dutch oven as a cooking container is heated by a lower burner and an upper burner is used. Yes (see, for example, Patent Document 1).

  In patent document 1, although detailed description is abbreviate | omitted about the control content which an operation control part performs based on the detection information of the temperature detection sensor which detects the temperature of the exclusive pan for Dutch ovens, an operation control part However, as Dutch oven cooking, it is suggested to perform cooking that heats for a set time while performing thermal power control.

  Further, in Patent Document 1, detailed descriptions of the lower burner and the upper burner are omitted, but in general, the lower burner and the upper burner are formed by primary air taken in when gaseous fuel is supplied in an ejected state. A so-called Bunsen combustion type is employed in which primary combustion is performed and secondary combustion is performed using the outside air taken into the grill as secondary air.

JP 2012-200394 A

In the case where a large-capacity cooking container such as a dedicated pan for a Dutch oven is used as the cooking container, it is included in the food to be stored in the cooking container due to storing a large amount of water in the cooking container. There may be a lot of moisture.
When the amount of moisture contained in the food to be stored in the cooking container is large, when the cooking container is heated by the lower burner and the upper burner, a large amount of water vapor is released from the cooking container and released. Water vapor fills the upper part inside the grill.

When water vapor fills the upper part of the inside of the grill, the partial pressure of water vapor contained in the secondary air for combustion used in the secondary combustion of the upper burner increases, and the oxygen concentration in the secondary air for combustion increases. As a result, the upper burner may cause poor combustion.
Therefore, it is necessary to avoid that the upper burner burns in a poorly burned state when a large amount of water vapor is released from the cooking vessel.

  The present invention has been made in view of the above circumstances, and its purpose is to burn the upper burner by releasing a large amount of water vapor from a cooking vessel with a simple configuration that effectively utilizes the original configuration. The object of the present invention is to provide a grill that can appropriately avoid burning in a bad state.

The grill of the present invention is installed at the bottom of a grill cabinet and heats a cooking container stored in the grill cabinet from below, and a bunsen combustion type lower burner, and the grill installed at the ceiling of the grill cabinet Bunsen combustion type upper burner is provided to heat the container from above,
A temperature detection sensor for detecting the temperature of the cooking vessel, and an operation control unit for controlling the combustion operation of the lower burner and the upper burner based on detection information of the temperature detection sensor, The first characteristic configuration is
When the operation control unit assumes that the elapsed time since the start of heating has accumulated water in the cooking container in a state where the lower burner and the upper burner are combusted and heating of the cooking container is started. When the set reference time at which the stored water is predicted to boil is reached, it is determined that the temperature of the cooking container detected by the temperature detection sensor is in a water storage state that is equal to or lower than the boiling determination temperature. In this case, the combustion of the upper burner is stopped.

  In other words, in addition to ingredients such as meat, fish, and vegetables, water may be stored in the cooking container as food to be cooked, but water is different from other foods such as meat, fish, and vegetables. When the boiling point is reached, even if the heating is continued, the heat energy from the heating is used for the latent heat for the phase change that changes from water to water vapor. The temperature rise of the cooking container heated by the lower burner and the upper burner is moderately or eliminated, and the temperature of the cooking container is balanced, and the temperature of the cooking container is boiled while the amount of moisture in the cooking object is large. Maintains temperature and does not increase significantly.

That is, when the elapsed time from the start of heating reaches the reference time when it is assumed that the stored water is boiled when it is assumed that the cooking container has been filled with water, it is detected by the temperature detection sensor. Whether or not a large amount of water is contained in the object to be cooked accommodated in the cooking container can be determined based on whether or not the temperature of the cooking container is equal to or lower than the boiling determination temperature.
And when there is much moisture contained in the to-be-cooked object accommodated in the cooking container, if heating of a cooking container is continued, the amount of water vapor | steam emitted from the to-be-cooked object accommodated in the cooking container will be about combustion of an upper burner. If the allowable limit is exceeded, the combustion of the upper burner may be adversely affected.

  Therefore, in a state where the operation control unit combusts the lower burner and the upper burner and starts heating the cooking container, water whose cooking container temperature is equal to or lower than the boiling determination temperature based on the detection information of the temperature detection sensor. When it is determined that the fuel is in the storage state, the combustion of the upper burner is stopped in advance by preventing the upper burner from being burned in a poorly burned state.

  Moreover, when the water storage state is determined based on the detection information of the temperature detection sensor provided for heating control of the cooking container, the combustion of the upper burner is stopped when it is determined that the water storage state is present. Therefore, it is possible to appropriately avoid the upper burner from being burned in a poorly burned state with a simple configuration using the detection information of the temperature detection sensor that is originally provided.

  In short, according to the first characteristic configuration of the present invention, it is appropriate that the upper burner burns in a poorly burned state by releasing a large amount of water vapor from the cooking container with a simple configuration that effectively utilizes the original configuration. A grill that can be avoided can be provided.

The second feature configuration of the grill of the present invention is in addition to the first feature configuration described above,
There is provided a cooking menu command section for commanding a cooking menu to be executed from among a plurality of cooking menus,
The operation control unit is configured to control the combustion operation of the lower burner and the upper burner based on the cooking menu commanded by the cooking menu command unit,
Among the plurality of cooking menus, there is a set water cooking where the amount of water vapor released from the cooking object stored in the cooking container is predicted to exceed the allowable limit for combustion of the upper burner,
The operation control unit is
In the state where the cooking of the set water is commanded by the cooking menu command unit, the detection information of the temperature detection sensor is displayed in the state where the lower burner and the upper burner are burned and heating of the cooking container is started. Based on the setting reference state where it is predicted that the amount of water vapor released from the cooking object accommodated in the cooking container will increase, the combustion of the upper burner is stopped, and the lower burner Is configured to continue combustion, and
When the cooking menu command unit instructs the cooking menu other than the set water cooking, the water storage is performed in a state where the lower burner and the upper burner are burned and heating of the cooking container is started. When it is determined that the state is in a state, the combustion of the upper burner is stopped.

That is, when the cooking menu is commanded by the cooking menu command unit, the operation control unit controls the combustion operation of the lower burner and the upper burner in order to perform heating cooking corresponding to the commanded cooking menu. .
For example, when the commanded cooking menu is “rice (rice cooking)”, the combustion operation of the lower burner and the upper burner is controlled in order to perform cooking corresponding to that “rice (rice cooking)”, and When the commanded cooking menu is “toast”, the combustion operation of the lower burner and the upper burner is controlled in order to perform cooking corresponding to the “toast”.

And the cooking menu commanded from the cooking menu command unit is set water cooking where it is predicted that the amount of water vapor released from the cooking object contained in the cooking container will exceed the allowable limit for combustion of the upper burner. In some cases, when the operation control unit burns the lower burner and the upper burner and starts heating the cooking container, the amount of water vapor released from the food to be cooked accommodated in the cooking container increases. When the set reference state is predicted, the combustion of the upper burner is stopped and the combustion of the lower burner is continued.
Incidentally, the setting reference state is a state in which the temperature of the cooking container detected by the temperature detection sensor rises to the setting reference temperature, for example.

  Note that it is predicted that the amount of water vapor released from the object to be cooked stored in the cooking container will exceed the allowable limit for combustion of the upper burner. This means that it is expected to have an adverse effect on the combustion of the burner, and the amount of water vapor released from the material to be cooked is high enough to cause the upper burner to burn poorly. It doesn't mean that there is.

  In other words, cooking menus that are set water dishes include “rice (cooked rice)” and “boiled dishes”, but when cooking for set water dishes, the food to be cooked contained in the cooking container When it reaches the set reference state where it is predicted that the amount of water vapor released from the tank will increase, the combustion of the upper burner is stopped and the combustion of the lower burner is continued, while continuing the cooking. The upper burner is prevented from burning in a poorly burned state.

  By the way, when performing cooking for setting water cooking, it is conceivable to stop the combustion of the upper burner from the start of cooking, but in this case, in the initial stage of cooking In addition to the lower burner when starting cooking, even when cooking for set-up water cooking, it will cause disadvantages such as insufficient heating and longer cooking time. The upper burner will also burn.

  In addition, when the cooking menu commanded from the cooking menu command unit is a cooking menu other than cooking of set water, the operation control unit cooks the elapsed time from the start of heating based on the detection information of the temperature detection sensor. The temperature of the cooking container detected by the temperature detection sensor when the water reaches the set reference time when the stored water is expected to boil when it is assumed that the container is full of water is used for boiling determination. When it is determined that the water storage state is lower than the temperature, the combustion of the upper burner is stopped.

In other words, in the case of a cooking menu other than cooking of set water, it is considered that the amount of moisture of the cooking object stored in the cooking container does not normally increase. Even in cooking menus other than cooking with set water, such as cooking with a large amount of moisture stored, there is a risk that the amount of moisture in the cooking object stored in the cooking container will increase.
In such a case, the water storage state is determined and the combustion of the upper burner is stopped, so that the upper burner is prevented from being burned in a poorly burned state.

  In short, the second characteristic configuration of the present invention is the cooking menu other than the setting water cooking when the cooking menu commanded from the cooking menu commanding unit is set water cooking, in addition to the operational effects of the first characteristic configuration. In either case, it is possible to provide a grill that can appropriately avoid burning the upper burner in a poorly burned state.

The third characteristic configuration of the grill of the present invention is in addition to the second characteristic configuration described above,
When the cooking controller other than the set water cooking is commanded by the cooking menu command unit, the operation control unit burns the lower burner and the upper burner and starts heating the cooking container. When the water storage state is determined, the combustion of the lower burner is stopped in addition to the combustion stop of the upper burner.

  That is, when it is determined that the temperature of the cooking container detected by the temperature detection sensor is equal to or lower than the boiling determination temperature when the elapsed time from the start of heating reaches the set reference time, The operation control unit stops the combustion of the lower burner in addition to the combustion stop of the upper burner.

That is, when it is determined that the water is stored, it is conceivable that the combustion of the lower burner is continued to continue cooking.
However, when it is determined that the water is in a stored state, for example, the user accidentally starts cooking with a large amount of water stored in the cooking container, and the cooking object is in an appropriate state in the cooking container. There is a high possibility that it is not housed.

  And if the food to be cooked is not housed in the cooking container in an appropriate state, if cooking is continued, there is a risk that the food to be cooked (foodstuff) will only be damaged, and the food will not be cooked properly. In addition to stopping the combustion, the combustion of the lower burner is also stopped to suppress the damage to the cooking object (foodstuff) contained in the cooking container.

  In short, the third characteristic configuration of the present invention can provide a grill that can suppress damage to the cooking object (foodstuff) accommodated in the cooking container, in addition to the operational effects of the second characteristic configuration.

The fourth characteristic configuration of the grill of the present invention is in addition to the third characteristic configuration described above,
When the operation control unit stops the combustion of the upper burner and the lower burner, a notification process for notifying that the moisture content of the cooking object stored in the cooking container is in a state exceeding an allowable amount. In that it is configured to run.

  That is, when it is determined that the water is stored and the combustion of the upper burner and the lower burner is stopped, the operation control unit is in a state where the moisture content of the cooking object stored in the cooking container exceeds the allowable amount. A notification process for notifying this is executed.

In this way, by executing the notification process, it is possible to prompt the user to confirm the accommodation state of the cooking object (foodstuff) contained in the cooking container.
Therefore, the user confirms the accommodation state of the food to be cooked (foodstuff) contained in the cooking container, for example, accommodates the food to be cooked in the cooking container in an appropriate state, and resumes cooking by heating. In addition, it is possible to satisfactorily take appropriate measures against the combustion of the lower burner being stopped.

  In short, according to the fourth characteristic configuration of the present invention, in addition to the operational effects of the third characteristic configuration, a grill that can appropriately perform appropriate measures against the combustion of the upper burner and the lower burner is provided. it can.

The fifth characteristic configuration of the grill of the present invention is in addition to any of the second to fourth characteristic configurations described above,
The heating power of the upper burner and the lower burner is configured to be adjustable and adjustable,
The setting reference time is set in accordance with the heating power of the upper burner and the lower burner.

  That is, since the set reference time is set according to the heating power of the upper burner and the lower burner, it is appropriately determined whether or not a large amount of water is contained in the food to be stored in the cooking container. Can do.

  In other words, the temperature rise gradient of the cooking container is set so that the greater the heating power of the upper burner and the lower burner, the steeper the inclination even if the moisture content of the cooking object accommodated in the cooking container is the same. By setting the reference time to a time according to the heating power of the upper burner and the lower burner, it is determined whether or not a large amount of water is contained in the food to be stored in the cooking container. Therefore, it is possible to make an appropriate determination regardless of the fluctuations.

  In short, according to the fifth feature configuration of the present invention, in addition to the operational effects of any one of the second to fourth feature configurations, whether or not a large amount of water is contained in the food to be stored in the cooking container. It is possible to provide a grill that can appropriately determine whether or not the upper and lower burners vary in thermal power.

The sixth characteristic configuration of the grill of the present invention is in addition to any of the second to fifth characteristic configurations described above,
When the cooking control command is instructed by the cooking menu command unit other than the set water cooking, the operation control unit burns the lower burner and the upper burner and starts heating the cooking container. The time required for the temperature of the cooking container to rise to the set determination temperature based on the detection information of the temperature detection sensor before the elapsed time from the start of heating reaches the set reference time. When the temperature equilibrium state is determined, the combustion of the upper burner and the lower burner is stopped.

  In other words, in addition to ingredients such as meat, fish and vegetables, water may be stored in the cooking container as food to be cooked. If it reaches, the heat energy from the heating will be used for latent heat to change from water to water vapor even if heating is continued. And the temperature rise of the cooking vessel heated by the upper burner is moderate or disappears, and the temperature of the cooking vessel is balanced.

That is, in a state where the lower burner and the upper burner are burned and heating of the cooking container is started, the cooking container is stored in the cooking container depending on whether or not the temperature of the cooking container detected by the temperature detection sensor is in an equilibrium state. It can be determined whether a large amount of moisture is contained in the food.
And when there is much moisture contained in the to-be-cooked object accommodated in a cooking container, if heating of a cooking container is continued, the amount of water vapor | steam discharged | emitted from the to-be-cooked object accommodated in a cooking container will burn the upper burner Exceeding the permissible limit, there is a risk of adversely affecting the combustion of the upper burner.

  Therefore, in a state where the operation control unit combusts the lower burner and the upper burner and starts heating the cooking container, before the elapsed time from the start of heating reaches the set reference time, the detection information of the temperature detection sensor is used. Based on this, when it is determined that the time required for the temperature of the cooking container to rise to the set determination temperature is equal to or greater than the set determination time, the upper burner is stopped by stopping the combustion of the upper burner and the lower burner. It avoids burning in the state of poor combustion beforehand, and also suppresses that the to-be-cooked object is damaged.

  In other words, when the temperature equilibrium state is determined before determining the water storage state, the upper burner fails to burn immediately by stopping the combustion of the upper burner and the lower burner without determining the water storage state. It is possible to appropriately avoid burning in a state and to appropriately prevent damage to the object to be cooked.

  In short, according to the sixth feature configuration of the present invention, in addition to the operational effects of the second to fifth feature configurations, it is possible to appropriately avoid the upper burner from burning in a poorly burned state, A grill capable of appropriately suppressing damage can be provided.

According to the seventh characteristic configuration of the grill of the present invention, in addition to the sixth characteristic configuration,
When the operation control unit stops the combustion of the upper burner and the lower burner, a notification process for notifying that the moisture content of the cooking object stored in the cooking container is in a state exceeding an allowable amount. In that it is configured to run.

  That is, when it is determined that the temperature of the cooking container is in a temperature equilibrium state and the combustion of the upper burner and the lower burner is stopped, the operation control unit determines that the moisture content of the cooking object stored in the cooking container is an allowable amount. The notification process for notifying that the state is exceeded is executed.

In this way, by executing the notification process, it is possible to prompt the user to confirm the accommodation state of the cooking object (foodstuff) contained in the cooking container.
Therefore, the user confirms the accommodation state of the food to be cooked (foodstuff) contained in the cooking container, for example, accommodates the food to be cooked in the cooking container in an appropriate state, and resumes cooking by heating. In addition, it is possible to satisfactorily take appropriate measures against the combustion of the lower burner being stopped.

  In short, according to the seventh characteristic configuration of the present invention, in addition to the operational effects of the sixth characteristic configuration, a grill that can appropriately perform appropriate measures against the combustion of the upper burner and the lower burner being provided is provided. it can.

In addition to the sixth or seventh characteristic configuration described above, the eighth characteristic configuration of the grill of the present invention includes:
In the state where the operation control unit combusts the lower burner and the upper burner and starts heating the cooking container, before determining the temperature equilibrium state, based on detection information of the temperature detection sensor, A temperature increase gradient of the cooking container before the temperature of the cooking container rises to a temperature corresponding to the boiling point of water is determined, and the setting determination temperature or the setting determination time is determined based on the calculated temperature increase gradient. It is in the point which is comprised.

  That is, before determining the temperature equilibrium state, the temperature rise gradient of the cooking container before the temperature of the cooking container rises to a temperature corresponding to the boiling point of water is obtained, and setting determination is performed based on the obtained temperature rise gradient. Since the temperature or setting determination time is determined, it is possible to accurately determine whether or not the temperature is in an equilibrium state.

  In other words, the temperature rise gradient of the cooking container before the temperature of the cooking container rises to a temperature corresponding to the boiling point of water becomes more gradual as the amount of water in the cooking object stored in the cooking container increases. Therefore, for example, as the temperature rise gradient is gentler, it is possible to accurately determine whether or not the temperature equilibrium state is established by decreasing the setting determination temperature or increasing the setting determination time.

  In addition, when the temperature rise gradient is such that the amount of water in the cooking object stored in the cooking container is large, the amount of water in the cooking object stored in the cooking container is small. Since the temperature rise gradient becomes gentle, if the temperature rise gradient falls within a moderate range, the amount of water in the cooking object stored in the cooking container is likely to be large. When the gradient is gentler, the setting judgment temperature is decreased or the setting judgment time is lengthened. The ratio for decreasing the setting judgment temperature and the ratio for increasing the setting judgment time are smaller than when the temperature rise gradient is in a steep range. Thus, it can be quickly determined that the temperature is in an equilibrium state.

  In short, according to the eighth characteristic configuration of the present invention, in addition to the operational effects of the sixth or seventh characteristic configuration, it is possible to provide a grill that can accurately determine whether or not it is in a temperature equilibrium state.

The ninth characteristic configuration of the grill of the present invention is in addition to the eighth characteristic configuration,
In a state where the operation control unit starts heating the cooking container by burning the lower burner and the upper burner, the temperature of the cooking container detected by the temperature detection sensor is determined from the set low temperature for determination. It is the point which is comprised so that the elapsed time until it may rise to the setting high temperature for use may be calculated | required as said temperature rise gradient.

That is, the temperature rise gradient of the cooking container before the temperature of the cooking container rises to a temperature corresponding to the boiling point of water, the temperature of the cooking container detected by the temperature detection sensor is changed from the setting low temperature for determination to the setting high for determination. It is obtained as the elapsed time until the temperature rises.
Note that the set low temperature for determination and the set high temperature for determination correspond to the boiling point of water as long as the temperature of the cooking container rises before the temperature rises to the temperature corresponding to the boiling point of water. Of course, it is set to a temperature lower than the temperature to be used.

  And since the temperature of the cooking container detected by the temperature detection sensor has reached the set low temperature for determination or the set high temperature for determination can be accurately recognized, the temperature of the cooking container is It is possible to accurately obtain the elapsed time from the setting low temperature for judgment to the setting high temperature for judgment as the temperature rise gradient of the cooking container, and as a result, accurately obtain the temperature rise gradient of the cooking container. Can do.

  In short, according to the ninth characteristic configuration of the present invention, in addition to the operational effects of the eighth characteristic configuration, it is possible to provide a grill that can accurately determine the temperature rise gradient of the cooking container.

The tenth characteristic configuration of the grill of the present invention is in addition to the eighth or ninth characteristic configuration,
When the operation control unit is instructed by the cooking menu command unit for the cooking menu other than the cooking of the set water, the temperature rising gradient is released from the food to be cooked contained in the cooking container. It is configured to stop the combustion of the lower burner and the upper burner when the amount is equal to or less than a set reference gradient that is expected to exceed the allowable limit for combustion of the upper burner. .

That is, in addition to ingredients such as meat, fish, and vegetables, water may be accommodated in the cooking container, but the specific heat of water is higher than that of ingredients such as meat, fish, and vegetables. Therefore, in the state where the lower and upper burners are burned and heating of the cooking container is started, the temperature rise gradient of the cooking container before the temperature of the cooking container rises to a temperature corresponding to the boiling point of water is The greater the amount of water contained in the food to be cooked contained in the container, the lower the tendency.
And if heating of a cooking container is continued, the amount of water vapor | steam discharged | emitted from the to-be-cooked object accommodated in the cooking container will increase, so that the moisture content contained in the to-be-cooked object accommodated in a cooking container increases.

  Therefore, in a state where the operation control unit burns the lower burner and the upper burner and starts heating the cooking vessel, the temperature of the cooking vessel rises to a temperature corresponding to the boiling point of water based on the detection information of the temperature detection sensor. The temperature rise gradient of the cooking vessel before the cooking is obtained, and the obtained temperature rise gradient may cause the amount of water vapor released from the cooking object stored in the cooking vessel to exceed the allowable limit for the combustion of the upper burner. When it is below the predicted set reference gradient, by stopping the combustion of the upper burner and the lower burner, it is possible to prevent the upper burner from being burned in a poorly burned state, and to suppress damage to the cooking object. It is.

  By the way, it is predicted that the amount of water vapor released from the object to be cooked stored in the cooking container will exceed the allowable limit for combustion of the upper burner. This means that it is expected to have an adverse effect on the combustion of the burner, and the amount of water vapor released from the material to be cooked is high enough to cause the upper burner to burn poorly. It doesn't mean that there is.

  In other words, by comparing the temperature rise gradient of the cooking vessel obtained before determining the temperature equilibrium state with the set reference gradient, the amount of water vapor released from the cooking object stored in the cooking vessel is about the combustion of the upper burner. If it is predicted that the condition will exceed the allowable limit, immediately stop the combustion of the upper burner and the lower burner without determining the temperature equilibrium state of the cooking vessel, so that the upper burner is in a poorly burned state. Combustion can be avoided appropriately, and damage to the object to be cooked can be suppressed appropriately.

  In short, according to the tenth characteristic configuration of the present invention, in addition to the operational effects of the eighth or ninth characteristic configuration, it is possible to appropriately avoid the upper burner from burning in a poorly burned state, and A grill capable of appropriately suppressing damage can be provided.

The eleventh characteristic configuration of the grill of the present invention is in addition to the tenth characteristic configuration,
When the operation control unit stops the combustion of the upper burner and the lower burner, a notification process for notifying that the moisture content of the cooking object stored in the cooking container is in a state exceeding an allowable amount. In that it is configured to run.

  That is, the temperature rise gradient of the cooking vessel is equal to or less than a set reference gradient at which the amount of water vapor released from the cooking object accommodated in the cooking vessel exceeds a permissible limit for combustion of the upper burner. As an example, when the combustion of the upper burner and the lower burner is stopped, the operation control unit performs notification processing for notifying that the moisture content of the cooking object stored in the cooking container exceeds the allowable amount. become.

In this way, by executing the notification process, it is possible to prompt the user to confirm the accommodation state of the cooking object (foodstuff) contained in the cooking container.
Therefore, the user confirms the accommodation state of the food to be cooked (foodstuff) contained in the cooking container, for example, accommodates the food to be cooked in the cooking container in an appropriate state, and resumes cooking by heating. In addition, it is possible to satisfactorily take appropriate measures against the combustion of the lower burner being stopped.

  In short, according to the eleventh characteristic configuration of the present invention, in addition to the function and effect of the tenth characteristic configuration, a grill that can appropriately perform an appropriate measure against the combustion of the upper burner and the lower burner being provided is provided. it can.

The twelfth characteristic configuration of the grill of the present invention is in addition to the tenth or eleventh characteristic configuration described above,
The heating power of the upper burner and the lower burner is configured to be adjustable and adjustable,
The set reference gradient is set in accordance with the heating power of the upper burner and the lower burner.

  That is, since the set reference gradient for comparing with the temperature rise gradient of the cooking container is set according to the heating power of the upper burner and the lower burner, when comparing the obtained temperature rise gradient of the cooking container with the set reference gradient The set reference gradient according to the heating power of the upper burner and the lower burner when the temperature rise gradient of the cooking vessel is obtained can be compared with the temperature rise gradient of the cooking vessel.

  Therefore, when comparing the determined temperature rise gradient of the cooking vessel and the set reference gradient, the setting criteria corresponding to the temperature rise gradient of the cooking vessel and the heating power of the upper burner and the lower burner when the temperature rise gradient is obtained. By contrasting with the gradient, it is possible to appropriately determine that the amount of water vapor released from the cooking object contained in the cooking vessel may exceed the allowable limit for combustion of the upper burner. it can.

  That is, the temperature rise gradient of the cooking container tends to become steeper as the heating power of the upper burner and the lower burner is larger, even if the amount of moisture in the cooking object stored in the cooking container is the same. The cooking standard contained in the cooking container is set by setting the standard setting slope to be compared with the temperature rising gradient of the container to the setting standard slope according to the heating power of the upper and lower burners when the temperature rising gradient of the cooking container is obtained. It is possible to appropriately determine that the amount of water vapor released from the object may exceed the allowable limit for combustion of the upper burner regardless of fluctuations in the heating power of the upper and lower burners.

  In short, according to the twelfth characteristic configuration of the present invention, in addition to the operational effects of either the tenth or eleventh characteristic configuration, the amount of water vapor released from the food to be cooked accommodated in the cooking container is the upper burner. It is possible to provide a grill that can appropriately determine that there is a possibility of exceeding the allowable limit for combustion regardless of fluctuations in the heating power of the upper burner and the lower burner.

A fire extinguishing process for extinguishing the burner 10 and the upper burner 11 is executed.

  In addition, in the combustion state of the lower burner 10 and the upper burner 11, when a change in the heating power is commanded by operating the heating power adjustment switch 47, the lower burner gas amount adjustment valve 36 and the upper burner gas amount adjustment valve 37 are operated. Thus, the thermal power adjustment process for changing the thermal power of the lower burner 10 and the upper burner 11 to “strong”, “medium”, and “weak” is executed.

As an automatic cooking control, when an “auto menu” cooking menu or a “cooking mode” cooking menu is instructed, the upper burner 11 and the lower burner 10 are based on preset cooking information. When the cooking menu “Auto Menu” is instructed, the lower burner 10 is finished when the predetermined cooking is completed. And the upper burner 11 is automatically extinguished.
When “timer cooking” is instructed, the lower burner 10 and the upper burner 11 are automatically extinguished when the cooking time has elapsed.

Further, the operation control unit W is configured to control the combustion of the lower burner 10 and the upper burner 11 based on the detection information of the presence / absence detection sensor S.
That is, for example, when the ignition command is commanded from the grill setting operation unit 6, the operation control unit W is based on the detection information of the presence / absence detection sensor S and the presence of the detected portion 40 </ b> H of the grill pan 9 and the lid 40. When it is determined that the non-existing state is detected, the non-existing process corresponding to the non-existing state is executed.

Specifically, the alarm process for operating the alarm device 55 such as an alarm buzzer is executed without executing the ignition process.
That is, without placing the grill plate 9 on the container support frame 21, the cooking container support portion L is stored in the set storage position of the grill cabinet 7, or the cooking container in which the grill plate 9 is mounted on the container support frame 21. When the support portion L is not stored in the proper set storage position of the grill cabinet 7, based on the detection information of the presence / absence detection sensor S, it is determined that the presence of the grill pan 9 is not detected, and the ignition process is performed. Execution will be restrained.

  Similarly, when the cooking pot 41 is placed on the container support frame 21 without placing the cooking pot 41 on the container support frame 21, the cooking container support L is stored in the set storage position of the grill cabinet 7. Even when the lid 40 is not attached to the cooking pan 41 and the cooking container support L is stored in the set storage position of the grill 7 and the lid 40 is attached to the cooking pan 41, When the grill storage 7 is not stored in the proper set storage position, based on the detection information of the presence / absence detection sensor S, it is determined that the presence of the detected portion 40H of the lid 40 is not detected, and the ignition process is performed. Execution will be restrained.

Further, the operation control unit W is configured to control combustion of the lower burner 10 and the upper burner 11 based on detection information of the exhaust temperature sensor 26.
That is, for example, when the temperature detected by the exhaust temperature sensor 26 exceeds the set upper limit value during the combustion of the lower burner 10 and the upper burner 11, the operation control unit W stops the combustion of the lower burner 10 and the upper burner 11. In addition, the fire extinguishing process is executed, and in addition, an alarm process for operating the alarm device 55 such as an alarm buzzer is executed.
That is, when the detected temperature of the exhaust temperature sensor 26 exceeds the set upper limit due to overheating of the cooking object, the combustion of the lower burner 10 and the upper burner 11 is stopped.

(Water control)
As described above, “rice” in the auto menu and “boil” and “steam” in the cooking mode store a large amount of water in the cooking pan 41, so that the cooking container K can be used as a cooking container K. This corresponds to “setting water cooking” in which the amount of water vapor released is predicted to exceed the allowable limit for the combustion of the upper burner 11.

  The operation control unit W stops the combustion of the upper burner 11 when the “setting water cooking” is instructed by the grill setting operation unit 6 and enters a setting reference state to be described later. When a burner adjustment process for continuing combustion or a cooking menu other than cooking of set water is commanded by the setting operation unit 6 for grill, the amount of water vapor released from the cooking object stored in the cooking container K increases. When it is determined that the “water food” is expected to exceed the allowable limit for the combustion of the burner 11, the burner stop process for stopping the combustion of the upper burner 11 and the lower burner 10, and accommodated in the cooking vessel K The notification process for notifying that the moisture content of the cooked food item is in a state exceeding the allowable amount is configured to be executed as a response control for water.

  That is, when the operation control unit W is instructed to “cook the set water” by the grill setting operation unit 6, the lower burner 10 and the upper burner 11 are burned and heating of the cooking container K is started. In the upper reference burner 11, when it is predicted that the amount of water vapor released from the cooking object stored in the cooking container K will increase based on the detection information of the container temperature detection sensor 13. The process of stopping the combustion and continuing the combustion of the lower burner 10 is executed as a burner adjustment process.

  That is, when a large amount of water vapor is released to the outside of the cooking container K when the cooking object stored in the cooking container K is heated, the partial pressure of water vapor contained in the combustion secondary air supplied to the upper burner 11 As a result of the increase in the amount of oxygen, there is a risk that an inconvenience leading to poor combustion of the upper burner 11 may occur due to a decrease in the oxygen concentration in the combustion secondary air, but such an inconvenience is prevented in advance. It is.

In the present embodiment, the setting reference state is the temperature of the cooking container K detected by the container temperature detection sensor 13, that is, the detection temperature of the container temperature detection sensor 13 is increased to the set reference temperature (for example, 78 ° C.). It is set to the state.
The set reference temperature only needs to be lower than the temperature corresponding to the boiling point of water. However, in order to stop the combustion of the upper burner 11 before a large amount of steam is generated, 90 ° C. or lower, It is preferable to set the temperature below 90 ° C., and in this embodiment, the temperature is set to 78 ° C.

  Incidentally, the combustion control content of the grill burner A that is set to perform automatic cooking for “set water cooking” is that the temperature of the cooking vessel K detected by the vessel temperature detection sensor 13 is a set reference temperature (for example, 78 ° C.). ) Is predetermined on the condition that the combustion of the upper burner 11 is stopped.

  Further, when the operation control unit W is instructed by the grill setting operation unit 6 to prepare a cooking menu other than cooking of the set water, the lower burner 10 and the upper burner 11 are burned to start heating the cooking container K. In this state, when it is determined that the amount of water vapor released from the cooking object stored in the cooking container K is a “water food” that is predicted to exceed the allowable limit for the combustion of the upper burner 11, The process of stopping the combustion of the burner 11 and additionally stopping the combustion of the lower burner 10 is configured to be executed as a burner stop process.

  By the way, when a cooking menu other than set water cooking is instructed, “Toast”, “Chicken thigh”, “Foil grill”, “Fish: fillet”, “Fish: grilled” "Cooking mode" "baking", "warming", "non-fry", "bread" is commanded, "timer cooking" is commanded, and "manual cooking" is Corresponds to the command.

When the operation control unit W determines that the food is a “water product” and stops the combustion of the upper burner 11 and the lower burner 10, a notification device 56 such as a voice notification device is used as a notification process. It is comprised so that it may operate | move and the process which alert | reports that the moisture content of the to-be-cooked object accommodated in the cooking container K is in the state exceeding allowable amount is performed.
In addition, as specific content of the notification operation of the notification device 56, it is preferable to specifically indicate the notification content such as “the amount of moisture in the cooking container is excessive”.

  That is, except when performing the above-mentioned “cooking with set water”, normally, cooking is not performed in a state where a large amount of water is stored in the cooking container K. When cooking is performed in a state where a large amount of water is stored in K, it is determined that the product is a “water product”, the combustion of the lower burner 10 and the upper burner 11 is stopped, and the upper burner 11 is stopped. It is possible to prevent the occurrence of inconvenience leading to poor combustion.

  That is, in this embodiment, although cooking is performed using either the grill pan 9 or the cooking pan 41 as the cooking container K, cooking is performed using the cooking pan 41 that can store a large amount of water. When performing, there is a possibility that the user mistakenly performs heat cooking in a state where a large amount of water is stored in the cooking pan 41. In such a case, it is determined that the food is a “water food”. The combustion of the lower burner 10 and the upper burner 11 is stopped, and the occurrence of inconvenience that leads to the defective combustion of the upper burner 11 is prevented in advance.

In addition, when it determines with it being a "water food", you may make it continue combustion of the lower burner 10, However, In this embodiment, the damage given to the to-be-cooked material (foodstuff) accommodated in the cooking container K In order to minimize (damage), in addition to stopping the combustion of the upper burner 11, the combustion of the lower burner 10 is also stopped.
Then, by executing the notification process, the user is prompted to confirm the accommodation state of the cooking object (food material) accommodated in the cooking container K.

  In the present embodiment, the operation controller W predicts that the amount of water vapor released from the cooking object stored in the cooking container K exceeds the allowable limit for the combustion of the upper burner 11. Is sequentially executed in three stages by the first determination process, the second determination process, and the third determination process, and the first determination process, the second determination process, and the second determination process are performed. 3 If any of the determination processes determines that it is a “water food”, the combustion of the upper burner 11 and the lower burner 10 is stopped, and the moisture content of the cooking object stored in the cooking container K is allowed. It is comprised so that the alerting | reporting process which alert | reports that it is in the state exceeding a capacity | capacitance is performed.

  That is, when it is determined by the first determination process that the food is “water food”, the combustion of the upper burner 11 and the lower burner 10 is stopped, so that the second determination process and the third determination process are executed. However, when the first determination process does not determine that the product is a “water product”, the second determination process is executed, and the second determination process indicates that the product is a “water product”. When the determination is made, the combustion of the upper burner 11 and the lower burner 10 is stopped, so that the third determination process is not executed, but when the second determination process does not determine that the food is “water food” Then, the third determination process is executed.

(First determination process)
As a first determination process, the operation control unit W combusts the lower burner 10 and the upper burner 11 and starts heating the cooking container K, and the temperature of the cooking container K detected by the container temperature detection sensor 13 is determined. The temperature rise gradient of the temperature of the cooking vessel K before the temperature rises to the temperature corresponding to the boiling point of water is obtained, and the amount of water vapor released from the food to be cooked stored in the cooking vessel K is the upper burner. Thus, a process of determining whether or not the value is equal to or less than a set reference gradient that is predicted to be in a state exceeding an allowable limit for 11 combustion is performed.

  Specifically, the process until the temperature of the cooking container K detected by the container temperature detection sensor 13 rises from the set low temperature for determination (for example, 77 ° C.) to the set high temperature for determination (for example, 90 ° C.). The time FT is obtained as a temperature rise gradient, and the obtained temperature rise gradient (elapsed time FT) exceeds the allowable limit for the combustion of the upper burner 11 by the amount of water vapor released from the cooking object stored in the cooking vessel K. A process of determining whether or not it is equal to or less than a set reference gradient (determination time) predicted to be in a state is executed.

The setting reference gradient is set in accordance with the heating power of the upper burner 11 and the lower burner 10, as shown in FIG.
That is, in this embodiment, when the heating power of the upper burner 11 and the lower burner 10 is “strong”, and when the heating power of the upper burner 11 is “weak” and the heating power of the lower burner 10 is “strong”. Is set to 35 seconds or more, and when the heating power of the upper burner 11 is “strong” and the heating power of the lower burner 10 is “weak”, the setting reference gradient (discrimination) is set. Time) is set to 100 seconds or more.

  In this embodiment, since the difference between the “strong” thermal power of the upper burner 11 and the “weak” thermal power is small, the set reference gradient when the upper / lower burner thermal power is “weak / strong” (discrimination) Time) is set to the same value as the set reference gradient (determination time) when the upper burner / lower burner is “strong / strong”, but the upper burner / lower burner is “weak / strong”. The setting reference gradient (determination time) at that time may be set to a value different from the setting reference gradient (determination time) when the upper burner thermal power / lower burner thermal power is “strong / strong”.

  That is, among the items to be cooked stored in the cooking container K, the specific heat of water is higher than the specific heat of other items to be cooked such as meat, fish and vegetables, so the size and material are known. When a specific cooking container K is used, it can be determined whether or not a large amount of water is contained in the cooking object stored in the cooking container K based on the temperature rise gradient of the cooking container K at a predetermined heating power. It is.

In the first determination process, whether or not a large amount of water is contained in the cooking object stored in the cooking container K due to the temperature rising gradient of the cooking container K at a predetermined thermal power, It is determined whether or not it is a “cooked item”.
When it is determined in the first determination process that the product is a “water product”, a large amount of water vapor is generated from the cooking container K to adversely affect the combustion of the upper burner 11 by continuing heating. It can be predicted that the probability is high.

(Second determination process)
The operation control unit W performs the second determination process after executing the first determination process in a state where the lower burner 10 and the upper burner 11 are combusted and heating of the cooking container K is started.
As the second determination process, the operation control unit W detects the container temperature after the first determination process is performed until the elapsed time after starting the cooking container K reaches a set reference time described later. Based on the detection information of the sensor 13, a process for determining a time required for the temperature of the cooking container K to rise to the set determination temperature and determining whether or not the obtained time is equal to or more than the set determination time is a temperature equilibrium state. Will be executed.

  And the temperature rise gradient of the cooking container K before the temperature of the cooking container K rises to a temperature corresponding to the boiling point of water is such that the more the moisture content of the cooking object stored in the cooking container K is, Therefore, for example, when the temperature rise gradient is gentler, it is possible to accurately determine whether or not the temperature is in the equilibrium state by decreasing the setting determination temperature or increasing the setting determination time.

  Further, when the temperature rise gradient is such that the amount of moisture in the cooking object stored in the cooking container K is large, the amount of moisture in the cooking object stored in the cooking container K is small. In comparison, since the temperature rise gradient becomes gentle, when the temperature rise gradient is in a gentle range, the amount of water in the cooking object stored in the cooking container K is likely to be large. When the setting judgment temperature is made smaller or the setting judgment time is lengthened as the temperature rise gradient is slower, the ratio of decreasing the setting judgment temperature or the ratio of increasing the setting judgment time is within a steep range. It is possible to quickly determine that the temperature is in an equilibrium state.

  In the present embodiment, the setting determination temperature is set to 1 ° C., and the operation control unit W is configured to determine the setting determination time FS based on the temperature increase gradient (elapsed time FT) obtained in the first determination processing. Has been.

Specifically, as shown in FIG. 12, the calculation coefficient FST is obtained based on the thermal power of the lower burner 10 and the upper burner 11 and the elapsed time FT (temperature rise gradient). Incidentally, the calculation coefficient FST is a value obtained by experiments.
The setting determination time FS is obtained by the product of the elapsed time FT and the calculation coefficient FST.

  That is, in the present embodiment, the calculation coefficient FST corresponding to the heating power of the lower burner 10 and the upper burner 11 and the magnitude of the elapsed time FT is obtained and set by the product of the obtained calculation coefficient FST and the elapsed time FT. By determining the determination time FS, it is possible to accurately determine whether or not the temperature is in the equilibrium state.

  In the present embodiment, since the difference between the “strong” thermal power of the upper burner 11 and the “weak” thermal power is small, the calculation coefficient FST when the upper / lower burner thermal power is “weak / strong” is The calculation coefficient FST when the upper burner thermal power / lower burner thermal power is “strong / strong” is set to the same value, but the arithmetic coefficient FST when the upper burner thermal power / lower burner thermal power is “weak / strong”. May be set to a value different from the calculation coefficient FST when the upper burner thermal power / lower burner thermal power is “strong / strong”.

That is, in the cooked food stored in the cooking container K, water is different from other cooked foods such as meat, fish, and vegetables. Will be used for the latent heat due to the phase change that changes to water or water vapor, and the temperature rise will be moderate or disappear, and the temperature will equilibrate.
Therefore, whether or not a large amount of water is contained in the cooking object stored in the cooking container K can be determined based on whether or not the temperature detected by the container temperature detection sensor 13 is balanced.

  In the second determination process, the time required for the detection temperature of the container temperature detection sensor 13 to rise by 1 ° C. is equal to or longer than the set determination time FS, and the cooking container is caused by the boiling of the water stored in the cooking container K. It is determined whether or not the temperature is in a temperature equilibrium state where the temperature of K is in an equilibrium state.

That is, the second determination process determines whether or not a large amount of water is contained in the cooking object stored in the cooking container K depending on whether or not the temperature is in an equilibrium state. It is determined whether or not it is an “object”.
In the second determination process, when it is determined that the temperature is in the “temperature equilibrium state”, there is a probability that a large amount of water vapor that may adversely affect the combustion of the upper burner 11 from the cooking vessel K due to continued heating. Can be predicted to be high.

(Third determination process)
When the elapsed time after starting the heating of the cooking container K reaches the set reference time in a state where the heating of the cooking container K is started by burning the lower burner 10 and the upper burner 11, the operation control unit W Judgment processing is executed.
The set reference time is determined as the time when the stored water is expected to boil when it is assumed that the elapsed time from the start of heating has been stored in the cooking container K full of water. The set reference time is set according to the heating power of the lower burner 10 and the upper burner 11, as shown in FIG.

As the third determination process, the operation control unit W burns the lower burner 10 and the upper burner 11 and starts heating the cooking container K. When the elapsed time from the start of heating reaches the set reference time, The temperature of the cooking container K detected by the container temperature detection sensor 13 is read, and the process of determining whether or not the temperature of the cooking container K is in a water storage state where the temperature is equal to or lower than the boiling determination temperature is executed. Has been.
In this embodiment, as shown in FIG. 13, the boiling determination temperature is set to 130 ° C., but the boiling determination temperature is set to an appropriate temperature of 100 ° C. or higher, for example, 110 ° C. Can be set.

  That is, in the cooked food stored in the cooking container K, water is different from other cooked foods such as meat, fish, and vegetables. Is used for the latent heat for the phase change that changes from water to water vapor, and the temperature rise of the cooking vessel K is moderately or eliminated, and the temperature of the cooking vessel K is balanced, so the elapsed time from the start of heating When it is assumed that the water stored in the cooking container K is full and the stored time reaches a reference time at which the stored water is predicted to boil, the detection temperature of the container temperature detection sensor 13 is equal to or lower than the boiling determination temperature. Whether or not a large amount of water is contained in the cooking object stored in the cooking container K can be determined depending on whether or not there is.

  In the third determination process, when it is assumed that the elapsed time from the start of heating has been stored in the cooking container K full, the container temperature is detected when the stored water reaches a reference time that is predicted to boil. It is determined whether or not the cooking object stored in the cooking container K is in a water storage state in which a large amount of water is contained depending on whether or not the temperature detected by the sensor 13 is equal to or lower than the boiling determination temperature.

That is, the third determination process is accommodated in the cooking container K depending on whether or not the temperature detected by the container temperature detection sensor 13 is equal to or lower than the boiling determination temperature when the elapsed time from the start of heating reaches the reference time. It is determined whether or not there is a “water storage state” in which a large amount of water is contained in the food to be cooked, that is, whether or not the food to be cooked is a “water food”.
And when it determines with it being a "water storage state" in a 3rd determination process, the probability that a lot of water vapor | steam which will have a bad influence on combustion of the upper burner 11 from the cooking container K will be generated by continuation of a heating. Can be predicted to be high.

(Flow chart of control for water)
As described above, the operation control unit W stops combustion of the upper burner 11 when the setting reference state is reached when “setting cooking of water” is commanded by the grill setting operation unit 6 as the water response control. If the cooking menu other than the set water cooking is instructed by the burner adjustment process for continuing the combustion of the lower burner 10 or the setting operation unit 6 for the grill, it is determined to be “water food”. Then, the burner stop process which stops combustion of the upper burner 11 and the lower burner 10, and the alerting | reporting process which alert | reports that the moisture content of the to-be-cooked object accommodated in the cooking container K is in the state exceeding allowable amount are performed. Thus, hereinafter, the water handling control will be described based on the flowchart of FIG.

When the combustion of the lower burner 10 and the upper burner 11 is started, if the auto menu, the cooking mode, and the timer cooking are already set, the water response control is started immediately. When combustion of the lower burner 10 and the upper burner 11 is started, if the auto menu, cooking mode, and timer cooking are not yet set, the waiting time for cooking mode setting should be started. become.
That is, as described above, since the auto menu, cooking mode, and timer cooking may be set immediately after the combustion of the lower burner 10 and the upper burner 11 is started, the combustion of the lower burner 10 and the upper burner 11 is started. At this time, if the auto menu, cooking mode, and timer cooking have not yet been set, the “water-related control” is started after the waiting time for cooking mode setting has elapsed.

  First, it is determined whether or not cooking is a preset water (# 1). If cooking is a preset water, then the temperature detected by the container temperature detection sensor 13 is a preset reference temperature (for example, 78 ° C.). It is determined whether or not the set reference state has been raised (# 11), and if it is the set reference state, burner adjustment processing is executed to stop combustion of the upper burner 11 and continue combustion of the lower burner 10 Is done.

  If it is determined in # 1 that the cooking is not set water, the first determination process is subsequently performed. In the first determination process, as described above, the elapsed time until the detection temperature of the container temperature detection sensor 13 rises from the determination low temperature (for example, 77 ° C.) to the determination high temperature (for example, 90 ° C.). FT is obtained as a temperature rise gradient, and the determined elapsed time FT (temperature rise gradient) is such that the amount of water vapor released from the cooking object stored in the cooking vessel K exceeds the allowable limit for combustion of the upper burner 11. This is a process for determining whether or not it is equal to or less than a set reference gradient (determination time) that is predicted to be.

  Next, based on the result of the first determination process, it is determined whether or not the temperature increase gradient (elapsed time FT) is equal to or less than the set reference gradient (determination time) (# 3), and is determined to be equal to or less than the set reference gradient. In the case of being burned, a burner stop process (# 9) for stopping the combustion of the upper burner 11 and the lower burner 10 is executed, and then the moisture content of the cooking object stored in the cooking container K exceeds the allowable amount. A notification process (# 10) for notifying that the state is present is executed.

  If it is determined at # 3 that the gradient is not less than the set reference gradient, the second determination process is executed (# 4). In the second determination process, as described above, based on the detection information of the container temperature detection sensor 13, the time required for the temperature of the cooking container K to rise to the set determination temperature is determined, and the determined time is set determination time FS. This is a process for determining whether or not the temperature equilibrium state is as described above.

  Next, based on the result of the second determination process, it is determined whether or not it is in a temperature equilibrium state (# 5), and if it is determined that it is in a temperature equilibrium state, the upper burner 11 and the lower burner 10 A burner stop process (# 9) for stopping the combustion is performed, and then a notification process (# 10) for notifying that the moisture content of the cooking object stored in the cooking container K exceeds the allowable amount. Executed.

  If it is determined in # 5 that the temperature equilibrium state is not established, it is then determined whether or not the elapsed time after starting the cooking container K has reached the set reference time (# 6), If the set reference time has not been reached, the second determination process # 4 and the determination process # 5 are repeated.

  If it is determined in # 6 that the elapsed time after starting the cooking container K has reached the set reference time, the third determination process is executed (# 7). As described above, the third determination process reads the temperature of the cooking container K detected by the container temperature detection sensor 13 when the elapsed time from the start of heating reaches the set reference time. This is a process for determining whether or not a water storage state in which the temperature is equal to or lower than a boiling determination temperature (eg, 130 ° C.).

  Next, based on the result of the third determination process, it is determined whether or not it is in a water storage state (# 8), and if it is determined that it is in a water storage state, the upper burner 11 and the lower burner 10 A burner stop process (# 9) for stopping the combustion is performed, and then a notification process (# 10) for notifying that the moisture content of the cooking object stored in the cooking container K exceeds the allowable amount. Executed.

  As described above, in this embodiment, in the case of “setting water cooking”, when the detection temperature of the container temperature detection sensor 13 reaches the setting reference temperature (for example, 78 ° C.), Since the burner adjustment process for stopping the combustion of the burner 11 and continuing the combustion of the lower burner 10 is executed, a large amount of steam is released from the cooking object stored in the cooking vessel K. It is possible to avoid the upper burner 11 from burning in a defective combustion state.

  Similarly, when a cooking menu other than cooking of set water is instructed by the grill setting operation section 6, cooking is performed in a state where the lower burner 10 and the upper burner 11 are burned and heating of the cooking container K is started. When it is determined that the amount of water vapor released from the food to be cooked contained in the container K is a “water food” that is predicted to exceed the allowable limit for combustion of the upper burner 11, the upper burner 11. In addition, since the combustion of the lower burner 10 is stopped, it is possible to avoid the upper burner 11 from being burned in a defective combustion state, and in addition, a large amount of moisture is present in the cooking vessel K. It is possible to avoid continuing cooking in an appropriate state.

  Moreover, when it determines with it being a "water food" and combustion of the upper burner 11 and the lower burner 10 is stopped, the moisture content of the to-be-cooked food accommodated in the cooking container K exceeds an allowable amount. Since the notification process for notifying that the state is present is executed, the user (cooker) recognizes that the cooking container K is in an improper state in which a large amount of water is stored. A treatment for a case where combustion of the upper burner 11 and the lower burner 10 is stopped, such as restarting cooking in an appropriate state in which an appropriate amount of water is stored, can be performed satisfactorily.
