JP, 2014-55724, A

  In a gas stove, it is desirable to be able to perform heating and cooking in the form of heating the food stored in the cooking vessel to a temperature of about 100 ° C. or lower than 100 ° C. (for example, 60 ° C.). For example, it is desirable to be able to perform heating and cooking in a form in which meat as a food to be cooked is stored in a pan as a cooking container and the food is heated to a low temperature (for example, 60 ° C.).

  However, in the low temperature cooking mode of the conventional gas stove, the temperature control of the cooking vessel is performed in the temperature range of 140 ° C. to 150 ° C. while switching the stove burner to the first thermal power and the second thermal power. The heating and cooking can not be carried out in the form of heating the to-be-cooked material stored in a temperature of about 100 ° C. or a temperature lower than 100 ° C. (for example, 60 ° C.).

In other words, since the stove burner that burns the fuel gas has the minimum amount of combustion that can perform appropriate combustion, the power (combustion amount) of the stove burner can not be made smaller than the minimum amount of combustion. The amount of combustion per unit time for heating the cooking container can not be made sufficiently small.
As a result, when the stove burner is continuously burned, heating and cooking can be performed by heating the food stored in the cooking vessel to a temperature of about 100 ° C. or a temperature lower than 100 ° C. (eg, 60 ° C.) It was nothing.

  The present invention has been made in view of the above-described circumstances, and an object thereof is that cooking can be performed in a form of heating the food stored in the cooking vessel to a temperature of about 100 ° C. or lower than 100 ° C. The point is to provide a gas stove.

The gas stove of the present invention is provided with a stove burner for heating a cooking vessel containing a food to be cooked, and an operation control unit for controlling the operation of the stove burner, and its characteristic configuration is as follows:
A low temperature cooking menu command unit for commanding a low temperature cooking menu is provided.
When the operation control unit is instructed to start the cooking operation of the low temperature cooking menu, the stove burner is operated under the heating condition for low temperature cooking to be burned in an intermittent combustion mode in which the combustion state and the extinguishment state are repeated. It is in the point where it is configured.

  That is, when a low temperature cooking menu is commanded by the low temperature cooking menu command unit and the start of the cooking operation of the low temperature cooking menu is instructed, the operation control unit burns in an intermittent combustion mode in which the combustion state and the extinguishment state are repeated. The stove burner is operated to burn under the heating condition for cooking.

  Therefore, in the burning state of the stove burner, the temperature of the cooking container storing the food increases, but in the fire extinguishing state of the stove burner, the temperature of the cooking container storing the food is normal temperature The temperature of the food stored in the cooking vessel is adjusted according to the temperature at which the food in the cooking vessel is heated, and the time for maintaining the burning state and the time for maintaining the extinguishing state. The food can be heated to a temperature of about 100 ° C. or lower than 100 ° C.

  In short, according to the characteristic configuration of the gas stove of the present invention, it is possible to heat the food stored in the cooking vessel to a temperature lower than about 100 ° C. or 100 ° C.

  A further characterizing feature of the gas stove of the present invention is that, when the operation control unit switches the stove burner from the extinguishment state to the combustion state during execution of the cooking operation of the low temperature cooking menu, ignition attention information is The point is that the voice notification unit is configured to make a notification.

  That is, when switching the stove burner from the extinguishing state to the burning state during the cooking operation of the low temperature cooking menu, the ignition warning information is notified from the voice notification unit so that the cook worker extinguishes the stove burner It can be known in advance that it will be in the state of combustion from.

  Thus, since the cook can know in advance that the stove burner will be in the burning state from the extinguishment state, the stove burner will be in the burning state from the extinguishing state when the cook is not conscious Thus, it is possible to improve usability by avoiding the occurrence of inconveniences such as surprises by the cook.

  In short, according to the further feature configuration of the gas stove of the present invention, usability can be improved by informing the cook in advance that the stove burner will be in the burning state from the extinguishing state.

  According to a further characterizing feature of the gas stove of the present invention, the low-temperature cooking heating condition is higher than the initial ignition burning amount of the initial ignition process in which the combustion state is first brought about at the start of the cooking operation of the low-temperature cooking menu. During the cooking operation of the low temperature cooking menu, the condition is set such that the amount of combustion for reignition at the time of reignition processing for switching from the extinguishment state to the combustion state is reduced.

  In other words, although the stove burner needs to be ignited with a large amount of combustion when the extinguishment state is maintained for a long time and is cold, it is more than when it is cold when it is once the combustion state is warm. It can be ignited with a small amount of combustion.

  In view of such a situation, the cooking operation of the low temperature cooking menu is more than the burning amount of the initial ignition processing of the initial ignition processing, in which the low temperature cooking heating condition is first brought into combustion at the start of the cooking operation of the low temperature cooking menu. The condition is set to reduce the amount of combustion for reignition at the time of reignition processing for switching from the extinguishment state to the combustion state during the execution of.

  And since the combustion amount for reignition processing at the time of reignition processing becomes small, when a stove burner changes from a extinguishment state to a combustion state by reignition processing, generation of a big fire is suppressed, so At the festival, it is possible to improve convenience by avoiding the occurrence of inconveniences such as surprises of the cook by the occurrence of a large fire.

  By the way, at the start of the cooking operation of the low temperature cooking menu, the cooks are fully aware that the stove burner will be in the burning state from the extinguishing state, so a big fire will occur at the time of initial ignition processing. Even if it occurs, it is possible for the cooks to avoid surprises, but the cooks are not fully aware that the stove burner goes from the extinguishment state to the burning state during the reignition process. If, for example, a large fire occurs, there is a risk that the cook will be surprised or otherwise inconveniently caused, but such inconvenience can be avoided to improve usability.

  In short, according to the further characterizing feature of the gas stove of the present invention, the occurrence of a large fire during the reignition process can be suppressed, and the usability can be improved.

According to a further characterizing feature of the gas stove of the present invention, a container temperature detection unit for detecting the temperature of the cooking container is provided.
If the temperature detected by the container temperature detection unit in the combustion state reaches the set target temperature in the combustion state, the extinguishing process for setting the extinguishment state is performed, and the detected temperature is the set target in the extinguishment state. When the reignition temperature lower than the temperature is reached, the condition is set to execute the reignition process.

  That is, when the detected temperature of the container temperature detection unit in the combustion state reaches the set target temperature, the extinguishing process to put the fire into a extinguished state is executed. Then, by performing the reignition process, the stove burner is burned in an intermittent combustion mode in which the combustion state and the extinguishment state are repeated.

  And since the stove burner is intermittently burned so as to set the temperature of the cooking container for storing the food to be set to the set target temperature based on the detected temperature of the container temperature detection unit, it is stored in the cooking container The temperature of the food can be properly maintained at a temperature suitable for low temperature cooking.

  In short, according to the further feature configuration of the gas stove of the present invention, it is possible to appropriately heat the food stored in the cooking vessel to a temperature suitable for low temperature cooking.

  A further characterizing feature of the gas stove according to the present invention is that the low-temperature cooking heating condition is a set small combustion amount that is lower than the reignition combustion amount when the reignition thermal power maintenance time elapses after the reignition processing is performed. The point is set to switch to.

  That is, during execution of the cooking operation of the low temperature cooking menu, when the stove burner is switched from the extinguishment state to the combustion state by the reignition process, the stove burner is burned for reignition until the heat power maintenance time for reignite elapses. The state in which the amount of combustion is continued is continued, and thereafter, when the reignition thermal power maintenance time elapses, the stove burner is switched to the set small amount of combustion which is lower than the amount of reignition combustion.

As described above, when the stove burner is switched from the extinguishment state to the combustion state by the reignition processing, the stove burner is continued to be burned with the reignition combustion amount until the reignition thermal power maintenance time elapses. This makes it possible to stabilize the combustion of the stove burner ignited by the amount of combustion for reignition.
As the reignition heating power maintaining time, for example, about 3 seconds can be set.

  And when the thermal power maintenance time for reignition passes, by switching the stove burner to the set small combustion amount lower than the reignition combustion amount, the heat load such as the small amount of the food stored in the cooking vessel is small Occasionally, heating to a low temperature (for example, 60 ° C.) lower than about 100 ° C. or 100 ° C. can be favorably performed while suppressing excessive heating of the food to be cooked.

  In summary, according to the further feature configuration of the gas stove of the present invention, the stove burner switched to the combustion state by the reignition process can be stably burned, and moreover, the amount of the food to be cooked stored in the cooking vessel is small Even when the heat load is small, heating the food to a low temperature (for example, 60 ° C.) lower than about 100 ° C. or 100 ° C. can be performed well.

  A further characterizing feature of the gas stove of the present invention is that the set small combustion amount is a combustion amount corresponding to the minimum heating power of the heating power adjustment range of the stove burner.

  That is, during execution of the cooking operation of the low temperature cooking menu, when the heating power maintenance time for reignition elapses after switching the stove burner from the extinguishment state to the combustion state by the reignition processing, the stove burner is lower than the reignition combustion amount Although switching to the set small combustion amount is made, as the set small combustion amount, the combustion amount corresponding to the minimum heating power of the heating power adjustment range of the stove burner is defined.

  Therefore, after the heating power maintenance time for reignition elapses, the cooking container is heated with the amount of combustion corresponding to the minimum heating power of the heating power adjustment range of the stove burner. Even when the heat load is very small, such as when the amount is very small, the temperature of the food is about 100 ° C. or lower than 100 ° C. (eg, 60 ° C.) while appropriately suppressing excessive heating of the food. It can be well heated to ° C.

  In short, according to the further feature configuration of the gas stove of the present invention, even when the heat load is very small, for example, the amount of the food stored in the cooking vessel is considerably small, the food is about 100 ° C. or more than 100 ° C. It is also possible to heat well to low temperatures (eg 60 ° C.).

According to a further characterizing feature of the gas stove of the present invention, a load detection unit for detecting the heat load of the cooking vessel containing the food to be cooked is provided.
The low-temperature cooking heating condition is set to a condition in which the reignition thermal power maintenance time is extended as the heat load detected by the load detection unit increases.

  That is, during execution of the cooking operation of the low temperature cooking menu, when the stove burner is switched from the extinguishment state to the combustion state by the reignition process, the stove burner is burned for reignition until the heat power maintenance time for reignite elapses. The state where the amount of combustion is continued is continued, and thereafter, when the reignition thermal power maintenance time elapses, the stove burner is switched to a set small combustion amount lower than the reignition combustion amount, but the reignition thermal power maintenance time However, as the heat load of the cooking container storing the food to be detected detected by the load detection unit increases, the adjustment is made longer.

  Therefore, when the amount of the food stored in the cooking vessel is large and the heat load is large, the temperature of the food can be appropriately raised by the stove burner burning with the amount of combustion for reignition. When the amount of the food stored in the cooking vessel is small and the heat load is small, the time for the stove burner to burn with the reignition combustion amount is shortened, and the food is heated excessively. Can be suppressed.

  In short, according to the gas stove of the present invention, either when the amount of the food stored in the cooking vessel is large and the heat load is large or when the amount of the food stored in the cooking vessel is small and the heat load is small. Also, the food can be cooked well.

  A further characterizing feature of the gas stove according to the present invention is a ventilating apparatus in which the operation control unit continuously performs the ventilation operation at least from the start to the end of the cooking operation of the low temperature cooking menu. In this respect, a ventilation command for starting the ventilation operation and a stop command for stopping the ventilation operation are issued.

  That is, when the cooking operation of the low temperature cooking menu is started, a ventilation command to start the ventilation operation is instructed to the ventilator, so the cooking exhaust generated when performing the cooking operation of the low temperature cooking menu is It can be discharged properly.

  In addition, since the ventilation device is operated in a mode in which the ventilation operation is continuously performed at least from the start of the cooking operation of the low temperature cooking menu to the end, the disadvantage such as damaging the ventilation device Can be avoided.

  That is, when the ventilator is operated in the intermittent combustion mode in which the combustion state and the extinguishment state are repeated when the ventilation device is operated according to the cooking operation of the low temperature cooking menu, the combustion state is established according to the combustion of the stove burner It is conceivable to operate the ventilator intermittently by sending a ventilation command to the ventilator and instructing the ventilator to stop when the fire is extinguished. In this case, the ventilator repeatedly repeats. By being activated, there is a possibility that the ventilator may be easily damaged, for example, the driving electric motor for the ventilator may be damaged.

  On the other hand, in this feature configuration, since the ventilator is continuously operated from the start to the end of the cooking operation of the low temperature cooking menu, the disadvantage such as damage to the ventilator is caused. Can be avoided.

  In summary, according to the further feature configuration of the gas stove of the present invention, the cooking exhaust gas generated when performing the cooking operation of the low temperature cooking menu can be appropriately discharged, and the inconvenience such as damaging the ventilation device occurs. Can be avoided.

  A further feature of the gas stove according to the present invention is that after the operation control unit is in the combustion state and after switching to the extinguishing state between the start and the end of the cooking operation of the low-temperature cooking menu The ventilation air volume command is commanded to the ventilation device so that the ventilation air volume after the additional setting time has elapsed since switching to the extinguishment state is reduced rather than the ventilation air volume until the additional setting time elapses In that it is configured to

  That is, when the cooking operation of the low temperature cooking menu is performed, a large amount of cooking exhaust gas is discharged when the stove burner is in the combustion state and during the time after the additional setting time elapses after switching to the extinguishing state. However, after the stove burner is switched to the extinguishment state, after the additional set time has elapsed, the amount of the cooking exhaust gas becomes small even if the cooking exhaust gas is not discharged or discharged.

  In view of such a situation, the additional setting time after the stove burner is switched to the extinguishing state than the ventilation air volume from when the stove burner is in the burning state and until the additional setting time elapses after switching to the extinguishing state In order to reduce the ventilation air volume after the passage of time, the ventilation air volume command is commanded to the ventilation system, so that the cooking exhaust generated when performing the cooking operation of the low temperature cooking menu is properly discharged. Can operate the ventilation system while saving energy.

  That is, when performing the cooking operation of the low temperature cooking menu, it is conceivable to always operate the ventilator with a large ventilation air volume, but in that case, after switching the stove burner to the extinguishing state, after the additional setting time has elapsed Also in this case, the ventilation system is operated with an amount of ventilation air flow more than necessary, and the energy required to operate the ventilation system is wasted.

  In short, according to the gas stove of the present invention, the ventilation device can be operated while saving energy while appropriately discharging the cooking exhaust gas generated when performing the cooking operation of the low temperature cooking menu.

If it is determined that the first burner 1A is not in combustion, then the temperature detected by the first temperature detector 8 is the reignition temperature (e.g., 46) It is determined whether the temperature is less than or equal to 0 ° C. (# 13).
Then, when the temperature detected by the first temperature detection unit 8 is lower than the reignition temperature (for example, 46 ° C.), a “medium” ventilation command of the ventilation air volume is commanded (# 14), and then the first A reignition process is performed to reignite the burner 1A (# 15).
Although not described in the flowchart of FIG. 6, when performing the reignition process, that is, immediately before performing the reignition process, the ignition attention process of notifying the ignition alert information by the voice notification unit F is performed. It will be
After the reignition process of # 15 is performed, the process proceeds to the process of # 17 described later.

  When it is determined in # 12 that combustion is in progress, it is determined whether or not the first burner 1A has been switched to the state of burning with the set small combustion amount (# 16), and it is determined that switching has not been completed. It is determined whether the reignition thermal power maintenance time has elapsed (# 17), and if the reignition thermal power maintenance time has elapsed, the first burner 1A is burned at the set small combustion amount The process of switching to the state is executed (# 18).

  If it is determined in # 16 that switching has been completed, if it is determined in # 17 that the thermal power maintenance time for reignition has not elapsed, and if # 18, the first burner 1A is set small combustion After the process of switching to the state of burning by the amount is performed, next, it is determined whether the temperature detected by the first temperature detection unit 8 is equal to or higher than the set target temperature (for example, 50 ° C.) (# 19), When the temperature detected by the first temperature detector 8 is equal to or higher than the set target temperature (for example, 50 ° C.), the extinguishing process is performed to extinguish the first burner 1A (# 20).

  If it is determined that the temperature detected by the first temperature detection unit 8 is not less than the reignition temperature (for example, 46 ° C.) at # 13, and if the temperature detected by the first temperature detection unit 8 is a setting target at # 19. If it is determined that the temperature is not higher than 50 ° C., for example, the process proceeds to the process of # 9, and similarly, when the extinguishing process of # 20 is performed, the process proceeds to the process of # 9. become.

  If it is determined in # 9 that the set cooking time (for example, 40 minutes) has elapsed, it is determined whether or not the first burner 1A is in combustion (# 21), and the combustion is in progress. When it is determined that the first burner 1A is extinguished (# 22), and when it is determined that the first burner 1A is not being burned, a "medium" ventilation command of the ventilation air volume is commanded (# 23).

  After executing the fire extinguishing process of # 22 or after instructing the "medium" ventilation command of the ventilation air volume at # 23, subsequently, the continuous set time (eg, It is determined whether 3 minutes has elapsed (# 24), and when the continuous setting time (for example, 3 minutes) has elapsed, a stop command to stop the ventilation operation is commanded (# 25).
