Description

  The present invention comprises a heating means for heating the cooking container and a control means for controlling the operation of the heating means, and the control means is heating the cooking container with the heating means. The present invention relates to a heating cooker configured to execute a blowout prevention control for controlling the operation of the heating means to prevent the food from being blown out.

Conventionally, the cooking device having the above configuration has been configured as follows.
That is, in the case of performing cooking by boiling with a heating cooker, the temperature of the cooking container immediately before boiling is in a state where the operation for stewed cooking is commanded by operating a manually operated command operation tool (boiled food key). When the temperature is reached, the control means controls the heating means so that the heating means repeats a different heating amount every predetermined time based on an operation pattern set in advance according to the type of cooking as the spill prevention control. Some were configured to control operation. In other words, a large heating amount state and a small heating amount state are alternately switched every set time, and multiple types of operation patterns with different time ratios between the large heating amount state and the small heating amount state are cooked. Depending on the type designated by the device user, an appropriate one is automatically selected, and the operation of the heating means is controlled according to the selected content ( For example, see Patent Document 1.) The determination as to whether or not the temperature of the cooking container is the temperature immediately before boiling is, for example, determined that the temperature is immediately before boiling when the temperature of the cooking container reaches a preset temperature (for example, 90 ° C.). Or the temperature immediately before boiling is estimated based on the temperature rise gradient of the temperature of the cooking container after the start of heating, and the temperature of the cooking container is set to the estimated temperature. Then, it is judged that the temperature is just before boiling.

  In addition, when performing cooking by cooking in a heating cooker, for example, the cooked food is heated at a large heating amount until it boils. When cooking in a form that continues the amount state, there is a possibility that the amount of heating is weak and the taste can not penetrate to the inside of the cooked item, but by configuring as described above, heating with a small amount of heating By repeatedly heating with a large amount of heat, cooking is heated at the highest possible temperature so that the taste penetrates into the cooked food and can be cooked deliciously, but it does not cause spillage It is.

See JP-A-2002-95585.

However, according to the above-described conventional configuration, it is not always possible to prevent proper spilling, and there is a possibility that spilling may not be prevented.
In addition, when performing stewed cooking, even if the type of cooking is the same, not only the material and size of the cooking container, but also the amount of food stored in the cooking container, The types of ingredients contained in the broth, the amount of the ingredients, etc. are not always the same, and the conditions for such cooking are different.

  However, in the above-described conventional configuration, when preventing spillage, an appropriate one is selected from a plurality of operation patterns according to the type of cooking. Therefore, it is difficult to cope with all of the differences in the various cooking conditions when actually cooking. Depending on the difference, there is a possibility that the spillage cannot be prevented in an appropriate state.

  An object of the present invention is to provide a cooking device capable of preventing spilling while being able to appropriately cook and cook regardless of the difference in conditions when cooking.

A first characteristic configuration of the present invention includes a heating unit that heats a cooking container, and a control unit that controls the operation of the heating unit, and the control unit heats the cooking container with the heating unit. A heating cooker configured to execute a spill prevention control for controlling the operation of the heating means to prevent the food from being spilled during cooking, and a target heating amount of the heating means is set. Manual operation heating amount setting means for setting, temperature detection means for detecting the temperature of the cooking container, and manually operated blow-out prevention operation command means for commanding execution of the blow-out prevention control, the control If the execution of the spill prevention control is not instructed by the spill prevention operation command means, the heating means sets the target heating amount to be the target heating amount set by the heating amount setting means. When the normal heating control for controlling the operation of the means is executed, and when the normal heating control is being executed, execution of the blowout prevention control is instructed by the blowout prevention operation command means The normal heating control is stopped, and the blowout prevention control is executed. The control means performs the blowout prevention control by the blowout prevention operation command means as the blowout prevention control. Detecting the temperature detection means by setting a target temperature having a predetermined temperature range with the detection value of the temperature detection means when commanded as an upper limit value and a value lower than the upper limit value by a set amount as a lower limit value so that the value falls between the upper limit and the lower limit value, the heating amount of said heating means, the normal heating control before the browning prevention control execution is commanded Alternating between a large heating amount state that is adjusted to a heating amount when cooking is performed or a heating amount for cooking less than that, and a small heating amount state that is adjusted to a heating amount for preventing spillage that is less than the heating amount for cooking It is the point which is comprised so that operation | movement of the said heating means may be controlled so that it may switch to .

  According to the first characteristic configuration, the control means is set to the target heating amount set by the heating amount setting means, unless execution of the blow-out prevention control is instructed by the blow-out prevention operation command means. The normal heating control for controlling the operation of the heating means is executed. When such normal heating control is being executed, if execution of the blowout prevention control is instructed by the blowout prevention operation command means, the execution of the normal heating control is stopped and the blowout prevention control is executed. That is, the target temperature is set based on the detected value of the temperature detecting means when the execution of the blow-out preventing control is instructed by the blow-out preventing operation command means, and heating is performed so that the detected value of the temperature detecting means becomes the target temperature. The operation of the means is controlled.

In addition, when cooking is performed by boiling, when cooking is performed while heating the cooking container containing the cooked food with a heating means at a large heating amount, the cooked product will boil and be removed from the cooking container. If the device user is instructed by the manual operation to execute the spill prevention control before the spill occurs, the temperature detection means detects the temperature of the cooking container at that time. Based on the detected value , the target temperature is set, and thereafter, the normal heating control for controlling the operation of the heating unit to stop at the target heating amount set by the heating amount setting unit is stopped to detect the temperature. The operation of the heating means is controlled so that the detected value of the means becomes the target temperature.

  That is, the operation of the heating means is performed so that the temperature of the cooking container does not cause the spillage but becomes a relatively high target temperature after the execution of the spill prevention control is instructed by the spill prevention operation command means. Therefore, even if the equipment user does not perform an operation for heat adjustment, cooking can be performed deliciously by infiltrating the taste of the cooked food by cooking at a temperature as high as possible. It is possible to prevent the food from being blown out.

  In addition, whether or not there is a risk of the food being blown out of the cooking container is determined by humans, and the target temperature in the subsequent heating operation is set based on the result of the determination. Even if the cooking conditions such as the state of the food, such as the size of the soup, the amount of the broth, the type of utensils contained in the broth, and the amount of the utensils may vary, the target temperature should always be appropriate. Can be set. As a result, although it is necessary for a human to determine whether or not there is a risk of the spilled food, when performing the spill prevention control, the stewed cooking can be properly performed without any troublesome operation.

Therefore, it has become possible to provide a heating cooker that can prevent the spilling while being able to appropriately cook and cook regardless of the difference in conditions when cooking.
In addition, the control means includes a large heating amount state in which the heating amount of the heating means is adjusted to the heating amount for cooking, and heating for preventing the spilling that the heating amount of the heating means is smaller than the heating amount for cooking. The operation of the heating means is controlled so as to alternately switch to the small heating amount state adjusted to the amount. In this way, the control means performs control to alternately switch the heating amount of the heating means between the heating amount for cooking and the heating amount for preventing spillage, so that the spillage can be reliably prevented. Therefore, the control configuration can be simplified.
For example, as the above-mentioned blowout prevention control, a temperature for heating that can appropriately perform stew cooking is set in a state that does not cause blowout, and the detected temperature detected by the set temperature and the temperature detection means It is conceivable that the heating amount of the heating means is proportionally controlled so that the deviation from the above becomes small. However, when configured in this way, the optimum temperature as the heating temperature as described above is for cooking. However, according to the first characteristic configuration of the present invention, there is a disadvantage that a complicated process for obtaining such an optimal temperature is required and the control configuration is complicated. Simple control that only switches the heating amount of the heating means alternately in two stages, while it is possible to prevent the spillage reliably because it is adjusted to the heating amount for preventing spillage intermittently. The control arrangement may be those simple because there.

In addition to the first feature configuration, the second feature configuration of the present invention is provided with manually operated temperature change command means for commanding the change of the target temperature, and the control means is the temperature change command means at the temperature change command means. When the change of the target temperature is instructed, the upper limit value of the target temperature is changed to the decreasing side .

According to the second feature configuration, if the timing at which the device user manually operates the spill prevention operation command means is slightly delayed and the target temperature is a temperature at which the spill occurs or a temperature higher than that, then the spill Spilling may occur when prevention control is executed. Therefore, the target temperature can be changed and set by commanding the change of the target temperature by the temperature change command means.
Therefore, for example, as described above, even if a higher temperature that is likely to cause spillage is set as the target temperature, it is appropriately spilled by changing and setting the target temperature with the temperature change command means. Can be prevented.

A third characteristic configuration of the present invention includes a heating unit that heats the cooking container, and a control unit that controls the operation of the heating unit, and the control unit heats the cooking container with the heating unit. A heating cooker configured to execute a spill prevention control for controlling the operation of the heating means to prevent the food from being spilled during cooking, and should be heated by the heating means A manually operated heating amount setting means for setting a target heating amount and a manually operated blowing prevention operation command means for instructing execution of the blowout prevention control are provided, and the control means is the blowout prevention operation command means. If the execution of the spill prevention control is not commanded in step 1, the normal heating process for controlling the operation of the heating means so as to reach the target heating amount set by the heating amount setting means. When the execution of the blowout prevention control is instructed by the blowout prevention operation command means when the normal heating process is being executed, the manual operation is performed thereafter. When the heating amount setting means is operated and the small heating amount state in which the target heating amount is decreased and the large heating amount state in which the target heating amount is increased are repeatedly performed, the target heating in the small heating amount state is performed. The amount of time and the maintenance time for maintaining the small heating amount state, and the target heating amount in the large heating amount state and the maintaining time for maintaining the large heating amount state are stored as an operation pattern for preventing spilling. After storing the operation pattern for prevention, the execution of the normal heating control is stopped, and the operation pattern for preventing spillage is used as the spill prevention control. In that it is configured to control operation of the heating means.

According to the third characteristic configuration, the control unit is set to the target heating amount set by the heating amount setting unit unless the execution of the blowout prevention control is instructed by the blowout prevention operation command unit. The normal heating control for controlling the operation of the heating means is executed. And, when performing such normal heating control, when the execution of the blowout prevention control command is commanded by the blowout prevention operation command means, after that, the heating amount setting means is operated manually, When the small heating amount state in which the target heating amount is decreased and the large heating amount state in which the target heating amount is increased, the target heating amount in the small heating amount state and the maintenance time for maintaining the small heating amount state, And the target heating amount in a large heating amount state and the maintenance time which maintains the large heating amount state are memorize | stored as an operation pattern for blowing-out prevention.

  In addition, when cooking with stew, when cooking with a large amount of heat heated by a heating means when cooking with stew, there is a risk of spilling. The user of the device previously commands the execution of the spill prevention control by operating the spill prevention operation command means by manual operation. Then, the food is heated with a large heating amount and the cooked product is boiled and seems to be blown out from the cooking container, but before the spilled, the equipment user manually operates the heating amount setting means so as not to cause spilling. The change is adjusted to achieve a small target heating amount. Then, when the spilled state is settled by changing and adjusting to such a small target heating amount, the equipment user manually operates the heating amount setting means to perform the stew cooking at the highest possible temperature, thereby performing the target heating. Increase the amount. And, if the heating amount is increased in this way, the cooked product will boil and almost spill out of the cooking container, so that the equipment user operates the heating amount setting means by manual operation again and does not cause spilling. Change and adjust so that the target heating amount is small.

  In this way, according to the judgment of the device user, the heating amount setting means is manually operated, and the small heating amount state in which the target heating amount is reduced and the large heating amount state in which the target heating amount is increased are repeatedly performed. When the control means, the target heating amount in the small heating amount state and the maintenance time for maintaining the small heating amount state, and the target heating amount in the large heating amount state and the maintenance time for maintaining the large heating amount state, It is stored as an operation pattern for preventing spillage.

  Then, after storing the operation pattern for preventing spillage, the operation of the heating unit is not controlled so as to reach the target heating amount set by the heating amount setting unit, but the stored operation pattern for preventing spillage is stored. Thus, the operation of the heating means is controlled.

  In other words, when the blowout prevention control is executed, the operation of the heating means is controlled by an operation pattern similar to the operation pattern performed based on human judgment, so that the device user does not perform an operation for adjusting the heating. However, cooking can be performed at a temperature as high as possible while preventing the food from being blown out, and the food can be cooked deliciously by allowing the taste to penetrate into the food without causing the food to blow up.

  Therefore, it has become possible to provide a heating cooker that can prevent the spilling while being able to appropriately cook and cook regardless of the difference in conditions when cooking.

According to a fourth feature configuration of the present invention, in addition to the third feature configuration, when the control means stores the operation pattern for preventing spillage, a notification means for notifying the fact is provided.

According to the fourth characteristic configuration, when the control means stores the operation pattern for preventing spillage, the notification means notifies the user, so that the device user executes the spill prevention control. It can be recognized that the state has been reached. Therefore, since it is not necessary to monitor the state of the cooking container thereafter, other operations can be performed, which is convenient.

It is configured.

  As shown in FIG. 9, the setting panel 50 corresponding to each of the burners 1a, 1b, 1c is spilled as a manually operated spill prevention operation command means for commanding execution of spill prevention control as will be described later. A prevention switch 51, a temperature change switch 52 as a manually operated temperature change command means for instructing a change in target temperature as will be described later, and a display panel 54 for displaying various information are provided.

  Then, the combustion control unit H performs the operation of the burner 1 so that the target heating amount set by the heating amount setting operation unit 29 is reached unless the execution of the blowing prevention control is instructed by the blowing prevention switch 51. The normal heating control is configured to be executed. When the normal heating control is being executed, the execution of the normal heating control is stopped when the execution of the blowout prevention control is instructed by the blowout prevention switch 51. As the spill prevention control, the target temperature is set based on the detection value of the temperature sensor 11 when the execution of the spill prevention control is instructed by the spill prevention switch 51, and the detection value of the temperature sensor 11 is the target temperature. It is comprised so that operation | movement of the burner 1 may be controlled.

  That is, the combustion control unit H, as the spill prevention control, sets the heating amount of the combustor 1 to the amount of heating when the normal heating control is executed before the execution of the spill prevention control is commanded or less. The operation of the burner 1 is controlled so as to switch alternately between a large heating amount state adjusted to the cooking heating amount and a small heating amount state adjusted to a heating amount for preventing spillage less than the cooking heating amount. It is configured as follows.

Hereinafter, based on the flowcharts shown in FIGS. 10 and 11, the control operation of the burner 1 by the combustion controller H will be described.
When the point-extinguishing switch 32 is operated from the OFF state to the ON state and an ignition command is commanded, the combustion control unit H executes an ignition process for the corresponding combustor 1 (Steps 1 and 2). In other words, the flow control valve 18 is opened so that the heating amount of the combustor 1 becomes the heating amount for the initial ignition, and the ignition operation is performed by giving a drive signal to the spark plug 7 and the ignition is confirmed by the thermocouple 8. Then, the ignition operation is stopped and the ignition process is terminated. Next, normal heating control is executed (step 3). In this normal heating control, the opening degree of the flow rate control valve 18 is adjusted so that the target heating amount set by the heating amount setting operation unit 29 is obtained. When the blowout prevention switch 51 is not operated, the normal heating control is executed until the point extinguishing switch 32 is operated from the ON state to the OFF state and fire extinguishing is commanded (steps 4 and 5). When fire extinguishing is commanded, fire extinguishing processing is executed (step 6). That is, the flow control valve 18 is closed to extinguish the burner 1.

  When execution of the spill prevention control is instructed by the spill prevention switch 51 while the normal heating control is being executed, the execution of the normal heating control is stopped and the spill prevention control is executed (steps 7 and 8). ). Incidentally, when cooking is performed such that such spilling occurs, the normal heating control is adjusted to a large heating amount of the maximum value (fifth stage) in the five-step heating amount adjustment range.

  In this spill prevention control, as shown in FIG. 11, when the temperature of the cooking container is detected by the temperature sensor 11 and a target temperature as described later is not set, execution of the spill prevention control is instructed. The detected value of the temperature sensor 11 is set and stored as an initial reference value (Tk0) (steps 81, 82, 83). At that time, the display panel 54 displays the set temperature and the state that the blow-out prevention control is being executed. Thereafter, when the temperature change switch 52 is turned on, every time the temperature change switch 52 is operated, the stored temperature (reference value Tk) is limited to a value obtained by reducing the initial reference value (Tk0) by 5 ° C. The temperature is decreased by 0 ° C. (steps 84, 85, 86). Therefore, the reference value Tk can be changed and set within a range in which the initial reference value Tk0 is the maximum value and a value that is 5 ° C. lower than the initial reference value Tk0 is the minimum value. For example, if the initial reference value Tk0 is 100 ° C., the reference value Tk can be changed and set in the range of 95 ° C. to 100 ° C. Then, the target temperature is set in a state having a predetermined temperature range with the reference value Tk set in this way as an upper limit value and a value Ta lower than the reference value Tk by a set amount (for example, 10 ° C.) as a lower limit value. (Step 87).

  When the target temperature is set as described above, if the flag F is not set at that time, the heating amount Q1 for preventing the spilling out of the heating amount in the stove burner 1, for example, among the five stages The opening degree of the flow control valve 18 is adjusted to change to a small heating amount such as the first stage (minimum heating amount) or the second largest heating amount (steps 88 and 89). Incidentally, immediately after the blow-off prevention switch 51 is turned on, the flag F is not set, so the heating amount is changed to a small heating amount. By changing to the small heating amount in this way, as shown in FIG. 12, the detection value Tx of the temperature sensor 11, that is, the temperature of the cooked food is lowered and the spillage is settled. When the detected value Tx of the temperature sensor 11 falls below the lower limit value Ta of the target temperature, the heating when the normal heating control is executed before the execution of the blowout prevention control is commanded to the amount of heating in the stove burner 1 The opening degree of the flow control valve 18 is adjusted to change the heating amount Q2 for cooking to the same amount, and the flag F is set (steps 90, 91, 92).

  By changing the heating amount in the stove burner 1 to a large heating amount, the temperature of the cooking container rises. After setting the flag F, the detected value of the temperature sensor 11 sets the upper limit value Tk of the target temperature. If it exceeds, the heating amount in the stove burner 1 is changed to a heating amount for preventing spillage, and if the detected value of the temperature sensor 11 falls below the lower limit Ta of the target temperature, the heating amount in the stove burner 1 is changed to the heating amount for cooking. While repeatedly performing the change, a large heating amount state in which the heating amount in the stove burner 1 is set as a heating amount for cooking and a small heating amount state in which the heating amount in the stove burner 1 is set as a heating amount for preventing spilling are alternately repeated. Thus, the heating operation of the stove burner 1 is controlled so that the temperature of the cooking container falls between the upper limit value and the lower limit value of the target temperature (step 93). 96). Thereafter, when the point fire extinguishing switch 32 is operated from the ON state to the OFF state and fire extinguishing is instructed, the fire extinguishing process is executed, the flag F is reset, and the process is terminated (steps 9, 10, and 11).

[Second Embodiment]
Hereinafter, a second embodiment of the present invention will be described with reference to the drawings.
In the second embodiment, the control configuration of the combustion control unit H is different from that of the first embodiment, but the other configuration other than the control configuration of the combustion control unit H is the same as in the first embodiment. Here, only the differences in configuration will be described, and description of the same configuration will be omitted.

  That is, in this embodiment, if the combustion control unit H as the control means is not instructed to perform the blowout prevention control by operating the blowout prevention switch 51 as the blowout prevention operation command means, the heating amount setting means The heating amount setting operation unit 29 is configured to execute a normal heating process for controlling the operation of the stove burner 1 as the heating unit so that the target heating amount is set, and the normal heating process is performed. When the blowout prevention switch 51 is turned on and the execution of the blowout prevention control is instructed, the heating amount setting operation unit 29 is operated manually and thereafter the target is set. When the small heating amount state in which the heating amount is decreased and the large heating amount state in which the target heating amount is increased are repeatedly performed, the small heating amount state is The target heating amount in the state and the maintenance time for maintaining the small heating amount state, and the target heating amount in the large heating amount state and the maintenance time for maintaining the large heating amount state are stored as an operation pattern for preventing spillage. After the operation pattern for preventing spillage is stored, the execution of the normal heating control is stopped, and the operation of the burner 1 is controlled with the operation pattern for preventing spillage as the control for preventing spillage. It is configured. And when the combustion control part H memorize | stores the driving | running pattern for blowing up prevention, it has the structure which alert | reports this by the speaker 37 as an alerting | reporting means.

Hereinafter, based on the flowcharts shown in FIGS. 13 and 14, the control operation of the burner 1 by the combustion controller H will be described.
When the point-extinguishing switch 32 is operated from the OFF state to the ON state and an ignition command is instructed, the combustion control unit H performs the normal heating control after executing the ignition process for the stove burner 1 as in the first embodiment. Are executed (steps 21 to 23). If the blowout prevention switch 51 is not turned on, normal heating control is executed until the fire extinguishing switch 32 is operated from the ON state to the OFF state and a fire extinguishing command is issued (steps 24 and 29). When the fire extinguishing switch 32 is operated from the ON state to the OFF state and a fire extinguishing command is issued, a fire extinguishing process is executed (step 30).

  When the normal spill prevention switch 51 is turned on and the execution of the spill prevention control is instructed during the normal heating control, the flag F is set immediately after the spill prevention switch 51 is turned on. After that, it is determined whether or not the heating amount setting operation unit 29 is manually operated and the target heating amount is reduced to the heating amount for preventing the spilling, and the small amount of heating state is determined. After the 51 is turned on, if it is the first small heating amount state, the target heating amount at that time and the maintenance time in the small heating amount state are measured (steps 25, 26, 27, 28). ). Thereafter, when it is determined that the heating amount setting operation unit 29 is manually operated and the target heating amount is increased to the heating amount for cooking, the target heating in the large heating amount state is determined. The amount and the maintenance time in the large heating amount state are measured (steps 30, 31).

  It is determined that the heating amount setting operation unit 29 is manually operated to switch from the large heating amount state to the small heating amount state, and the second small heating amount state is entered after the blow-off prevention switch 51 is turned on. Then, based on the result measured as described above, for example, as shown in FIG. 15, the target heating amount Q3 in the small heating amount state, the maintenance time T1 for maintaining the small heating amount state, and the large heating amount The target heating amount Q4 in the quantity state and the maintenance time T2 for maintaining the large heating amount state are stored as an operation pattern for preventing spillage (step 33).

  In other words, when cooking is performed such that spilling occurs, the initial heating amount Qs adjusted at the beginning of cooking is adjusted to the maximum value (fifth step) in the five-step heating amount adjustment range. . Then, when the cooked food is boiled and is about to be spilled, the device user visually determines that and operates the heating amount setting operation unit 29 by manual operation to set the target heating amount to the amount Q3 for preventing the spilling. Will be reduced. The heating amount for preventing spilling (corresponding to the target heating amount Q3 in the small heating amount state) is, for example, the minimum value (first stage) in the heating amount adjustment range of five stages or one step higher than the minimum value 2 A small heating amount such as a step. Thereafter, when the spilled state of the food is settled, the device user manually operates the heating amount setting operation unit 29 to set the target heating amount to the heating amount for cooking (corresponding to the target heating amount Q4 in the large heating amount state). For example, the maximum heating (5th stage) of the 5 stages of heating amount adjustment range, or a large heating amount that is adjusted to the 4th stage large heating quantity, which is one stage lower than that. Cooking will be done. In this way, the combustion control unit stores an operation pattern for preventing spilling so that appropriate boiling cooking can be performed while preventing spilling by manual operation by the device user.

  In this embodiment, the target heating amount Q4 corresponding to the heating amount for cooking is exemplified as a heating amount on the smaller side than the initial heating amount Qs adjusted at the beginning of cooking, but depending on the cooking state May be the same amount of heating. Further, the target heating amount Q4 corresponding to the cooking heating amount may be a heating amount larger than the initial heating amount Qs adjusted at the beginning of cooking.

  After storing the operation pattern for preventing spilling, the speaker 37 is notified by voice that the operation pattern has been stored by the speaker 37 (step 34), and the execution of the normal heating control is stopped. Then, the flag F is set (steps 35 and 36). After the operation pattern for preventing spillage is stored and the flag F is set, the operation pattern for preventing spillage is maintained until the fire extinguishing command is instructed by operating the point extinguishing switch 32 from the ON state to the OFF state. Thus, the operation of the stove burner 1 is controlled. That is, a state in which the small heating amount state in which the heating amount of the stove burner 1 is adjusted to the target heating amount Q3 corresponding to the heating amount for preventing the spilling is continued only for the duration of the small heating time T1 has passed, The operation of the burner 1 is performed so that the large heating amount state in which the heating amount is adjusted to the target heating amount Q4 corresponding to the cooking heating amount is repeated alternately with the state in which the large heating amount maintaining time T2 elapses. Control is automatically performed (steps 37 to 42, 24, 25). Thereafter, when the fire extinguishing switch 32 is operated from the ON state to the OFF state and a fire extinguishing command is issued, the fire extinguishing process is executed, the flag F is reset, and the process is terminated (steps 43 and 44).
