Description

The present invention includes a stove burner for heating a cooking container, a temperature detection unit for detecting the temperature of the cooking container, a heating power adjusting unit for adjusting the heating power of the stove, a cooking mode setting unit for setting a stew mode, and a cooking mode setting unit. An operation control unit that controls operation is provided.
When the boiling cooking mode is set in the operation control unit, the detection temperature of the temperature detection unit becomes an equilibrium state corresponding to boiling of water after the start of heating in which the stove burner is burned with the initial thermal power. The present invention relates to a gas stove configured to set a high cut temperature at which combustion of the stove burner is stopped to a temperature higher than the equilibrium temperature based on the equilibrium temperature detected by the temperature detection unit.

By setting the stew mode, such a gas stove enables stew cooking of curry, stew, Chikuzen stew, meat potato, etc., and when the detection temperature of the temperature detection unit reaches the high cut temperature, the stove burner burns. By stopping the above, it is possible to avoid the scorching of the cooking object stored in the cooking container (see, for example, Patent Document 1).

Further, as another conventional example of the gas stove, the detection temperature of the temperature detection unit is changed after the detection temperature of the temperature detection unit becomes a boiling state corresponding to the boiling of water after the start of heating in which the stove burner is burned with the initial thermal power. When the equilibrium state is reached, the thermal power of the control burner is switched to a weak thermal power smaller than the initial thermal power, and after that, when the detection temperature reaches the lower limit temperature lower than the equilibrium temperature, the thermal power of the control burner is changed to a high thermal power larger than the low thermal power (initial). Temperature control type heating that switches to the same thermal power as the thermal power or smaller than the initial thermal power), and when the detected temperature reaches the upper limit temperature lower than the equilibrium temperature and higher than the lower limit temperature, the thermal power of the control burner is repeatedly switched to the low thermal power. Some are configured to perform the process (see, eg, Patent Document 2).

Japanese Unexamined Patent Publication No. 5-39926 Japanese Unexamined Patent Publication No. 2014-105961

The gas stove of Patent Document 1 stops the combustion of the stove burner when the detection temperature of the temperature detection unit reaches the high cut temperature, thereby avoiding the scorching of the cooking object stored in the cooking container. There was a risk that the scorching could not be avoided properly.

In other words, if the high-cut temperature is set to a temperature close to the equilibrium temperature, the combustion of the stove burner can be stopped before the object to be cooked stored in the cooking container becomes scorched. In this case, the cooking object is stored in the cooking container. The object to be cooked cannot be sufficiently simmered.
Therefore, the high-cut temperature is set to a temperature higher than the equilibrium temperature to some extent, and as a result, when the detection temperature of the temperature detection unit becomes the high-cut temperature and the combustion of the stove burner is stopped, There was a risk that the object to be cooked stored in the cooking container would be scorched.

In the gas stove of Patent Document 2, since the detection temperature of the temperature detection unit is maintained between the upper limit temperature lower than the equilibrium temperature and the lower limit temperature lower than the upper limit temperature, the cooking object stored in the cooking container. It is easy to avoid the occurrence of scorching of things, but as a result of the heating power given to the cooking container becoming insufficient, the cooking object stored in the cooking container cannot be sufficiently simmered, or the cooking object is simmered. There was a risk that it would be difficult to perform good stew cooking, such as a long cooking time.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a gas stove capable of simmering cooking while avoiding scorching of a cooking object stored inside a cooking container. It is in.

The gas stove of the present invention has a stove burner that heats a cooking container, a temperature detection unit that detects the temperature of the cooking container, a heating power adjusting unit that adjusts the heating power of the stove burner, and a cooking mode setting that sets a stew cooking mode. A unit and an operation control unit that controls operation are provided.
When the boiling cooking mode is set in the operation control unit, the detection temperature of the temperature detection unit becomes an equilibrium state corresponding to the boiling of water after the start of heating in which the stove burner is burned with the initial thermal power. Based on the equilibrium temperature detected by the temperature detection unit at that time, the high cut temperature at which the combustion of the stove burner is stopped is set to a temperature higher than the equilibrium temperature, and the feature thereof is The composition is
When the operation control unit reaches a boiling state corresponding to the boiling of water after the start of heating, the stove burner is burned in a form in which the thermal power is set to the initial thermal power at least for a part of the time. When the cooking heat treatment is executed and the detection temperature is lower than the high-cut temperature and higher than the burning monitoring temperature set higher than the equilibrium temperature, the heating power of the stove burner is increased. The point is that it is configured to perform a thermal power reduction process that lowers the initial thermal power.

That is, when the detection temperature of the temperature detector reaches a boiling state corresponding to the boiling of water after the start of heating by the stove burner, a cooking heat treatment in which the stove burner is burned in a form in which the heating power is set to the initial heating power at least in a part of the time zone is performed. Therefore, by setting the heating power to the initial heating power, the cooking object stored in the cooking container can be simmered while giving a large heating force to the cooking container, so that the simmering cooking can be performed satisfactorily.

Moreover, when the detection temperature of the temperature detection unit becomes lower than the high cut temperature and higher than the burnt monitoring temperature set higher than the equilibrium temperature, the thermal power reduction treatment for lowering the thermal power of the stove burner is lower than the initial thermal power. By lowering the heating power of the stove burner from the initial heating power, the detection temperature of the temperature detector reaches the high cut temperature, and the cooking object stored in the cooking container is burnt. It can be avoided.

In short, according to the characteristic configuration of the gas stove of the present invention, stew cooking can be performed satisfactorily while avoiding scorching of the cooking object stored inside the cooking container.

A further characteristic configuration of the gas stove of the present invention is such that the cooking heat treatment is restarted when the detection temperature becomes equal to or lower than the equilibrium temperature after the operation control unit executes the thermal power reduction treatment. There is a point.

That is, if the detection temperature of the temperature detection unit becomes equal to or lower than the equilibrium temperature after the heat reduction treatment is executed, the cooking heat treatment is restarted. Therefore, the stove burner is set to the initial heat at least in a part of the time. By burning the cooking container, the cooking object stored in the cooking container is simmered while giving a large heating force to the cooking container, so that the simmering cooking can be performed satisfactorily.

In other words, it is conceivable to maintain the heating power of the stove burner at a temperature lower than the initial heating power after the heat reduction treatment is executed, but in this case, the heating power given to the cooking container is insufficient and the cooking is cooked. However, by resuming the cooking heat treatment, the stew cooking can be performed satisfactorily while giving a large heating force to the cooking container.

In short, according to the further characteristic configuration of the gas stove of the present invention, the stewed cooking can be satisfactorily performed even after the thermal power reduction treatment is executed.

A further characteristic configuration of the gas stove of the present invention is a capacity determination process in which the operation control unit estimates the heating capacity based on the rise state of the detected temperature after the start of heating when the boiling mode is set. And based on the estimated heating capacity, the total cooking time from the time when the boiling state is reached to the time when the cooking heating process is stopped is set, and the elapsed time from the time when the boiling state is reached. The point is that the stove burner is configured to stop burning when the time reaches the total cooking time.

That is, the state of increase in the detected temperature after the start of heating by the stove burner changes depending on the heating capacity, such as the larger the heating capacity of the cooking object stored in the cooking container, the lower the increase gradient. In the treatment, the heating capacity is estimated based on the rising state of the detected temperature after the start of heating.
Then, based on the estimated heating capacity, the total cooking time from the time when the boiling state is reached to the time when the cooking heating process is stopped is set, and the elapsed time from the time when the boiling state is reached reaches the total cooking time. Then, the combustion of the stove burner is stopped.

That is, the heating capacity estimated by the capacity discrimination process, such as increasing the total cooking time from the time when the detection temperature reaches the boiling state corresponding to the boiling of water until the cooking heat treatment is stopped, as the heating capacity increases. When the elapsed time from the time of boiling reaches the total cooking time, the combustion of the stove burner will be stopped.

In this way, the total cooking time from the time when the boiling state is reached to the time when the combustion of the stove burner is stopped is set based on the heating capacity, and the elapsed time from the time when the boiling state is reached reaches the total cooking time. Then, the burning of the stove burner is automatically stopped, and the stew cooking is automatically terminated. Therefore, even if the user forgets that the stew cooking is in progress, burning or the like occurs. It is possible to properly finish the stewed cooking while avoiding the above.

In short, according to the further characteristic configuration of the gas stove of the present invention, stew cooking can be appropriately completed.

A further characteristic configuration of the gas stove of the present invention is that the operation control unit burns the stove burner for a first set time with a first thermal power smaller than the initial thermal power in the cooking heat treatment. The point is to execute a thermal power change type heat treatment in which the stove burner is repeatedly burned for a second set time with a second thermal power larger than the first thermal power.

That is, in the cooking heat treatment, the thermal power change type heat treatment is executed.
In the heat change type heat treatment, the heating power of the stove burner is set to the first heating power smaller than the initial heating power, the stove burner is burned for the first set time, and the heating power of the stove burner is larger than the first heating power. Since it is a process of repeating burning the stove burner for the second set time with thermal power, the state where the central side of the bottom of the cooking container is heated by the flame and the outer part of the bottom of the cooking container is heated by the flame. Since the bottom of the cooking container can be heated in a form in which the heating state is performed for an appropriate time, the entire cooking object stored inside the cooking container can be appropriately heated.

That is, when the thermal power of the conroburner is the first thermal power, a small flame hits the central part of the bottom of the cooking container, and when the thermal power of the conroburner is the second thermal power, a large flame is the outer portion of the bottom of the cooking container. In addition, the state of heating with the first thermal power is continued for the first set time, and the state of heating with the second thermal power is continued for the second set time. By setting the first set time and the second set time to a time suitable for appropriately heating the entire cooking object stored inside the cooking container, the central portion of the bottom of the cooking container can be set. Appropriately heat the entire cooking object stored inside the cooking container while performing the state of heating with the flame and the state of heating the outer part of the bottom of the cooking container with the flame at appropriate times. be able to.

By the way, one part of the bottom of the cooking container is concentrated by repeating the state of heating the central part of the bottom of the cooking container with the flame and the state of heating the outer part of the bottom of the cooking container with the flame. Since it is not heated, it becomes easy to avoid burning of the cooking object stored inside the cooking container.

In short, according to the characteristic configuration of the gas stove of the present invention, the entire cooking object housed inside the cooking container can be appropriately heated.

A further characteristic configuration of the gas stove of the present invention is that after the operation control unit continues the heating power changing type heating treatment for the cooking time for changing the heating power in the cooking heating treatment, the heating power of the stove burner is initially set. The point is to carry out a small-heat type heat treatment that maintains the heat power smaller than the heat power.

That is, after the heat change type heat treatment is continued for the cooking time for changing the heat power, the small heat type heat treatment for maintaining the heat power of the stove burner is executed, so that the heat treatment is stored inside the cooking container. After the entire cooking object is heated by the heat-changing heat treatment, the cooking object stored inside the cooking container can be sufficiently simmered by the small-heat heat treatment.

In other words, when cooking curry, stew, boiled Chikuzen, meat potatoes, etc., after heating the entire cooking object stored inside the cooking container, the cooking stored inside the cooking container is further performed. It is desirable to simmer the object over low heat, but such simmering can be done appropriately without any special operation.

In short, according to the further characteristic configuration of the gas stove of the present invention, it is possible to appropriately stew the cooking object stored in the cooking container over low heat without performing any special operation.

It is a schematic diagram which shows the structure of a gas stove. It is a figure which shows the outline of stew cooking. It is a flowchart which shows the control operation of stew cooking. It is a flowchart which shows the control operation of a cooking heat treatment.

Hereinafter, in the present embodiment, the stew mode among the stew mode, the water boiling mode, and the temperature setting mode will be described, and the description of the water boiling mode and the temperature setting mode will be omitted.

(Overview of stew mode)
The operation control unit H is configured to operate the stove burner 1 under the heating conditions for stew cooking when the stew mode is set.
Then, when the heating conditions for boiling cooking are such that the temperature detected by the temperature sensor 7 becomes a boiling state corresponding to the boiling of water after the start of heating in which the stove burner 1 is burned with the initial heating power, the heating power is initially started in at least a part of the time zone. The conditions are set to execute a cooking heat treatment that burns the stove burner 1 in the form of heating power.

Further, in the cooking heat treatment, the stove burner 1 is burned for the first set time with the first heat power smaller than the initial heat power, and the stove burner is burned with the second heat power larger than the first heat power for the second set time. It is configured to perform a thermal power change type heat treatment that repeats burning for a while.
In the present embodiment, the thermal power change type heat treatment is configured to be executed during the second step time (an example of the cooking time for changing the thermal power) as described later.

In the present embodiment, the initial thermal power is set to the medium thermal power corresponding to the ignition thermal power of the stove burner 1, the first thermal power is set to the small thermal power, and the second thermal power is set to the medium thermal power.
Further, the first set time is set longer than the second set time. That is, the first set time is set to, for example, 100 seconds, and the second set time is set to, for example, 20 seconds.

Further, in the present embodiment, as shown in FIG. 2, in the cooking heat treatment, the medium heat heat treatment for burning the stove burner 1 for the first process time is executed while the heat power is maintained at the medium heat power. After that, the thermal power change type heat treatment is executed during the second step time (an example of cooking time for changing the thermal power), and in addition, after the thermal power change type heat treatment, the thermal power is maintained at a smaller thermal power than the initial thermal power. Therefore, the conditions are set to execute a small heat type heat treatment in which the stove burner is burned for the third process time.
In this embodiment, the thermal power in the small thermal power type heat treatment is set to the small thermal power.

By the way, in the present embodiment, in the cooking heat treatment, the time zone in which the thermal power of the stove burner 1 is set to the initial thermal power is the time zone in which the medium thermal power heat treatment is executed and the second set time in the thermal power change type heat treatment. Corresponds to the corresponding time zone.

Further, when the stew mode is set, the operation control unit H executes and estimates the capacity determination process for estimating the heating capacity based on the rising state of the detected temperature T of the temperature sensor 7 after the start of heating. Based on the heating capacity, the total cooking time including the first process time, the second process time, the third process time, and the first to third process times is set.
Then, the operation control unit H is configured to stop the combustion of the stove burner 1 and end the stew mode when the elapsed time from the time when the boiling state is reached reaches the total cooking time.

(Details of stew mode)
When the operation control unit H issues an ignition command to the point fire extinguishing command unit 8 while the stew mode is set, ignition that burns the stove burner 1 with the ignition power (medium heat power corresponding to the initial heat power). The processing is executed, the heating of the cooking container J is started, and the capacity determination processing for estimating the heating capacity based on the rising gradient of the temperature detected by the temperature sensor 7 after the start of heating is executed.
In the present embodiment, as the ascending gradient, the ascending gradient from the detection temperature T of the temperature sensor 7 to 60 ° C. to 80 ° C. is detected.

In the present embodiment, the operation control unit H estimates the heating capacity in two stages of a large capacity and a small capacity in the capacity determination process, and determines the first process time, the second process time, the third process time, and , It is configured to execute a time setting process for setting the total cooking time in two stages.
That is, when the heating capacity is large, the total cooking time is set to, for example, 30 minutes, and when the heating capacity is small, the total cooking time is set to, for example, 20 minutes.

As the first process time, when the heating capacity is large, for example, 300 seconds (5 minutes) is set, and when the heating capacity is small, for example, 120 seconds (2 minutes) is set. ing.
As the second step time, when the heating capacity is large, for example, 900 seconds (15 minutes) is set, and when the heating capacity is small, for example, 300 seconds (5 minutes) is set. ing.
Therefore, as the third step time, when the heating capacity is large, for example, 10 minutes obtained by subtracting 20 minutes from 30 minutes is set, and when the heating capacity is small, for example, 7 minutes is subtracted from 20 minutes. It is configured to set 13 minutes.

The operation control unit H is configured to detect a boiling state corresponding to boiling of water and an equilibrium state corresponding to a state in which the boiling continues, based on the detection temperature T of the temperature sensor 7 after the start of heating. ing.
Then, when the equilibrium state is detected, the equilibrium temperature P, the high cut temperature R, and the scorching monitoring temperature Q are set (see FIG. 2).

In the present embodiment, in the detection of the boiling state (boiling detection), the time required for the detection temperature T of the temperature sensor 7 to rise to a predetermined temperature, for example, 1 ° C. is measured, and the measured time is a predetermined time, for example. It is configured to detect a boiling state when it exceeds 40 seconds.

Further, the detection of the equilibrium state (equilibrium detection) is performed from the detection temperature Te of the temperature sensor 7 at the end of the determination period to the determination period every fixed determination period, for example, every 30 seconds after the detection of the boiling state. The temperature difference ΔT (= Te−Tb) obtained by subtracting the detection temperature Tb of the temperature sensor 7 at the start time is obtained, and the temperature difference ΔT (= Te−Tb) is + 2 ° C. in a predetermined temperature range, for example, −2 ° C. or higher. It is configured to detect an equilibrium state when the temperature falls within the following temperature range (-2 ° C. ≤ ΔT ≤ + 2 ° C.).
Then, the detection temperature Te of the temperature sensor 7 at the end of the determination period when the equilibrium state is detected is set as the equilibrium temperature P.

Further, the operation control unit H is configured to set the high cut temperature R and the scorching monitoring temperature Q based on the equilibrium temperature P. In the present embodiment, 110 ° C., 120 ° C., and 130 ° C. are set as the judgment reference temperature, and the high cut temperature R and the scorching monitoring temperature Q are set based on the judgment reference temperature and the equilibrium temperature P. There is.

That is, when the equilibrium temperature P is less than 110 ° C., the high cut temperature R is set to 150 ° C., and the scorching monitoring temperature Q is set to 130 ° C.
Further, when the equilibrium temperature P is 110 ° C. or higher and lower than 120 ° C., the high cut temperature R is set to 160 ° C. and the scorching monitoring temperature Q is set to 140 ° C.
Further, when the equilibrium temperature P is 120 ° C. or higher and lower than 130 ° C., the high cut temperature R is set to 170 ° C., and the scorching monitoring temperature Q is set to 150 ° C.

Further, after the operation control unit H detects the boiling state, as described above, basically, a cooking heat treatment that sequentially performs a medium heat heat treatment, a heat change type heat treatment, and a small heat heat treatment is executed. However, when the detection temperature T of the temperature sensor 7 becomes higher than the high cut temperature R after the detection of the equilibrium state, the fire extinguishing process for extinguishing the stove burner 1 is executed.

Further, the operation control unit H forcibly changes the thermal power of the stove burner 1 to a small thermal power when the detection temperature T of the temperature sensor 7 becomes higher than the scorching monitoring temperature Q after the detection of the equilibrium state. (Example of thermal power reduction treatment) is executed, and then, when the detection temperature T of the temperature sensor 7 becomes equal to or lower than the equilibrium temperature P, the cooking heat treatment is restarted.
When the cooking heat treatment is executed (restarted) again, either medium heat heat treatment, heat change type heat treatment, or small heat heat treatment is performed according to the elapsed time from the time when the boiling state is detected. It will be executed.

Further, the operation control unit H switches the thermal power of the stove burner 1 to medium thermal power when the detection temperature T of the temperature sensor 7 becomes equal to or lower than the additional input determination temperature (for example, 95 ° C.) after detecting the equilibrium state. When the boiling state is detected, the cooking heat treatment is performed again according to the first process time, the second process time, and the total cooking time set based on the heating capacity estimated in the capacity determination process. Is configured to run.

(Details of control operation of operation control unit)
Next, the control operation of the operation control unit H in the stew mode will be described with reference to the flowcharts of FIGS. 3 and 4. However, in the following description, the description of the additional input handling process will be omitted.
As shown in FIG. 3, when the stew mode is set, it is first determined whether or not the ignition command is commanded (# 1), and if the ignition command is not commanded, the process waits until the ignition command is commanded.

If it is determined in # 1 that the ignition command has been commanded, the ignition process is executed (# 2), and then the capacity determination process is executed (# 3). That is, a process of detecting an ascending gradient from the detection temperature T of the temperature sensor 7 to 60 ° C. to 80 ° C. and estimating the heating capacity in two stages of a large capacity and a small capacity is executed.

After executing the capacity determination process, a time setting process for setting the total cooking time, the first process time, the second process time, and the third process time is executed (# 4), and then the temperature sensor 7 is detected. Whether or not it is in a boiling state (whether or not it is boiling detection) is determined based on the temperature T (# 5), and the process waits until the boiling state is reached (until boiling is detected).

When it is determined that boiling is detected in the process of # 5, timer measurement for measuring the total cooking time, the first process time, the second process time, and the time for managing the third process time is started (# 6). ), Then, an automatic heat treatment such as cooking heat treatment and forced small heat treatment is executed (# 7).

After that, it is determined whether or not the total cooking time has elapsed (# 8), and if the total cooking time has not elapsed, the automatic heat treatment is repeatedly executed, and when the total cooking time elapses, the stove burner 1 is turned on. Execute the fire extinguishing process (# 9) to extinguish the fire, and end the stew mode.

The automatic heat treatment will be described based on the flowchart of FIG.
First, it is determined whether or not the equilibrium state has been detected based on the detection temperature T of the temperature sensor 7 (whether or not the equilibrium state has been detected) (# 11), and if the equilibrium state has not been detected, , It is determined whether or not the equilibrium state is achieved based on the detection temperature T of the temperature sensor 7 (# 12).

When it is determined in the process of # 12 that the state is in equilibrium, the process of setting the equilibrium temperature P, the high cut temperature R, and the scorching monitoring temperature Q is executed (# 13).
When it is determined in the process of # 11 that the equilibrium state has been detected, and after the process of # 13 is executed, it is determined whether or not the detection temperature T of the temperature sensor 7 is larger than the high cut temperature R (#). 14) If it is determined that the temperature is large, the process proceeds to the fire extinguishing process # 9 in the flowchart of FIG. 3, and the stove burner 1 is extinguished.

When it is determined in the process of # 14 that the detection temperature T of the temperature sensor 7 is not larger than the high cut temperature R, it is subsequently determined whether or not the forced small thermal power by the forced small thermal power process is being executed. However, when it is determined that the forced small thermal power is not being executed (# 15), it is determined whether or not the detection temperature T of the temperature sensor 7 is larger than the scorching monitoring temperature Q (# 16), and the temperature sensor 7 is used. When it is determined that the detection temperature T is larger than the scorching monitoring temperature Q, a forced small thermal power treatment for changing the thermal power of the controller 1 to a small thermal power is executed (# 17).

If it is determined in the processing of # 15 that the forced small heating power is being executed, and after the forced small heating power processing of # 17 is executed, subsequently, is the total cooking time elapsed from the boiling state? Whether or not it is determined (# 18), and if the total cooking time has elapsed, the process proceeds to the fire extinguishing process # 9 in the flowchart of FIG. 3, and the stove burner 1 is extinguished.
When it is determined in the process of # 18 that the total cooking time has not elapsed, it is subsequently determined whether or not the detection temperature T of the temperature sensor 7 is equal to or lower than the equilibrium temperature P (# 19), and the temperature is determined. If it is determined that the detection temperature T of the sensor 7 is not equal to or lower than the equilibrium temperature P, the process proceeds to # 11.

When it is determined in the process of # 12 that the state is not in equilibrium, in the process of # 16, when it is determined that the detection temperature T of the temperature sensor 7 is not larger than the scorching monitoring temperature Q, and in the process of # 19. When it is determined that the detection temperature T of the temperature sensor 7 is equal to or lower than the equilibrium temperature P, the process shifts to the cooking heat treatment.

That is, it is determined whether or not the time from the boiling state has passed the first process time (# 20), and if the time from the boiling state has not passed the first process time, the stove burner 1 is used. The medium heat processing for changing the thermal power to medium heat is executed (# 21), and then the process shifts to the processing of # 11.
