It is a corresponding graph. Here, the equilibrium temperature of H9 is determined.
H10 and H11 are high heat
H12 and H13
Is the time when the fire was extinguished. H10 corresponds to 135 ° C
H11 corresponds to 145 ° C. Cut like this
The reason for changing the replacement temperature is to evaluate the thermal power and the amount of cooked rice.
Therefore, the degree of ease of burning is different.
Also, various discriminations such as standard cooking described later are performed.
No, but this puts time first over taste in early cooking
That's why. Next, when the process proceeds to step 232 in FIG.
The case will be described. In step 232, start
It is determined whether the MAX time has elapsed. Passing
If not, the process returns to step 224, and the loop process is executed.
Is If the time has elapsed, the process proceeds to step 233, where the time
To extend. Here, the time is extended by the temperature T
_kIs the temperature at which the heating power is switched from high to low.
The temperature indicates that the water has evaporated and the rice has been cooked
If the temperature is not reached, the MAX time
Even if it has passed, cook for an extended time
This is because you should cook until the end. However, step 2
34 determines whether 30 minutes have passed since the start.
If not, and if 30 minutes have not elapsed, step 224 is executed.
Loop processing is performed, but if 30 minutes have passed,
In this case, the process proceeds to step 235, and a rice cooking time error occurs.
Even if the rice cooking time is extended in step 233, from the start
After 30 minutes, it indicates that something went wrong.
In this case, the control unit 143 of FIG.
Performs error control and opens the safety valve 133a from the open state to the closed state
And extinguish the fire. The notifying unit 171 controls the control unit 14
Receives a signal indicating an abnormality from 3 and gives the user an abnormality.
Notify. Here, 30 minutes from the start,
Rice cooking time extension MAX data stored in the data storage unit 169
In the case of fast-cooking, the MAX data takes 20 minutes
As such, a 10 minute extension will be granted. this
And extend the time to cook until cooked
When the meal time is secured and the limit of extension is exceeded, abnormal
Be notified and safety is ensured. Therefore, error control
If any error occurs, the user must take action according to the error control.
Can be taken. The error control will be described with reference to FIG.
In the same manner as described above, when the safety valve 133a is closed.
In addition, first, close the solenoid valve 135, and after a certain time elapses
The safety valve 133a may be closed. The notification unit 17
1 is the same as the case described with reference to FIG. Next, from step 236 in FIG.
The case where the process proceeds to step 237 of FIG. Stay
At 237, the heat power is switched from high to low and then 9
It is determined whether 0 seconds have elapsed. Until 90 seconds have passed
Is a loop process, and after 90 seconds elapses, step 23 is executed.
Proceeding to 8, the processing of pan type determination 3 is performed. Pot type identification 3
Means that the temperature of the heated pan after 90 seconds elapses is 127
It depends on whether it is above or below ° C. That is, the discriminating unit 1 shown in FIG.
49 outputs a control signal for switching to the solenoid valve 135
The timer 151 determines whether 90 seconds have passed since
The temperature at the time when 90 seconds have elapsed is determined by the temperature sensor 107.
Recognize by measuring. Then, the determination unit 149
If the temperature is 127 ° C. or more,
Sea urchin type discrimination 1 (2) can be judged to be correct, 127 ° C not yet
If it is full, as shown in step 241, pan type discrimination 1
(2) can be determined to be an error. Until step 238
Indicates that the pan type is made of a material with low thermal conductivity.
In step 239, the
Separation is maintained, and in Step 241, a material having high thermal conductivity is used.
Is to be corrected. In step 241, an error is found in the determination of the type of pot.
Then, in step 242, in order to return control,
The heating power is switched from low to high. And step
At 243, the temperature T for switching from high to low heat_k Is 135 ° C
Is set to low cooking time t_j Is set to 7 minutes,
No cooking is set. On the other hand, at step 239
If it is determined that the pot type determination is correct, step 24
Go to 0 and cook on low heat t_j Is set to 5 minutes,
Cooking is set to be available. However, the time for cooking choi
t_c Is 30 seconds. To summarize the pot type discrimination, step 2
In step 13, the first determination (pan type determination 1) is performed.
In step 216, another determination (pan type determination 2) is performed.
By the three determinations, the pot type is almost correctly determined. That
As a result, processing to step 236 and step 2 described later
The processing from 44 onward is greatly different. However,
At step 214, it is determined that the pot type is a material having low thermal conductivity.
If the process is terminated and the process proceeds to step 236,
In pot 238, pan type determination 3 is performed again.
This is because materials with low thermal conductivity, such as
This is because it is easy to burn. In this way, the pot type discrimination is performed several times.
Over time to minimize mistakes
I have. And change the rice cooking control according to the judgment result
And it ’s delicious without any burning
It is possible to control the cooking of rice. The pot type is determined three times.
However, it may be performed only once. Or a set of two
May be combined. These are optional. Further
And the pot type discrimination data Δt₁ Rises between certain temperatures
The temperature is adopted as time, but the temperature rises for a certain period of time.
The pot type may be determined according to the degree. That is, the pot type here
The other is not limited to time information.
Is different from the reference pattern specified by the
Just do it. Further, the pot type discrimination data Δt_Two Is temperature equilibrium
The duration of the state, which is essentially the same equilibrium temperature time
However, in reality, it does not continue at a constant temperature, so
Temperature equilibrium until the temperature rises 6 ° C from the issued equilibrium temperature
6 ° C is not limited.
No. Further, in pot type determination 3 of step 238, the temperature
Is not used or it is 90 seconds
It is assumed that both temperature information and time information
Used. Further, the pot type discriminating unit 147 of FIG.
Is provided with a memory 155, and the memory 155
Data Δt₁ , Δt_Two But this is the step
Up to 211 can be switched to standard cooking or fast cooking
From this, the data measurement time and the judgment time are different, and Δt_Two
Is used to determine the type of pot, or the amount of heat and rice cooked
This is because both are used as discrimination. this
In this case, until the end of common control where mode switching is possible
Can be performed in the same sequence. However, as described later,
Data is stored, the pot type is determined, and based on the determination result
In the case of rice cooking control, data storage is necessary
Absent. After step 243, the steps of FIG.
224, and after step 240, the steps in FIG.

Correspondingly, step 610 corresponds to step 205 in FIG.
From Step 207 until the equilibrium temperature + 6 ° C is measured.
It corresponds to the processing in. Step 611 is the step in FIG.
This corresponds to step 236. In addition, the weakness of step 609
Cooking rice time t_j Is 6 minutes and 30 seconds. This is the figure
Because there is no processing in step 237 of FIG.
Make the rice cooking time longer by 1 minute and 30 seconds than Tep 240.
Because it is kept. Step 606 corresponds to step 21 in FIG.
Step 607 is a new process corresponding to No. 5. Stay

Pot thickness / choice cooking presence / absence determination unit 173 and pot thickness determination unit in FIG. 7
As can be seen in comparison with 159, this configuration is different.
You. The difference is that the pot thickness and
When temperature rises from 130 ° C to 140 ° C after temperature equilibrium
While the pot thickness discrimination is performed based on the interval,
Separate part 159 is based on the equilibrium temperature,
This is the point that is determined. However, the pot thickness discriminating unit in FIG.
159 includes pot thickness / choice cooking presence / absence determination unit 173
Then, the control corresponding to that may be performed. Next, steps 621 and 622 in FIG.

kcal / h. This is the low heat of step 611
The same applies to the case. (Modification 5) FIG. 33 shows still another embodiment of the present invention.
Control method of gas stove with rice cooker function
FIG. 34 is a first flowchart, and FIG. 34 is a second flowchart.
FIG. 35 is a third flowchart, and FIG. 36 is a fourth flowchart.
FIG. FIG. 37 is a schematic block diagram of the thermal power / cooked rice amount discriminating unit.
It is a lock figure. With reference to FIG.
Unlike a gas stove with a rice cooker that cooks,
The rice cooking control starts immediately after the rice, and the flat
Equilibrium temperature TH₀ It is determined whether or not is detected. Detected
Loop processing is performed until the processing is performed.
The processing is performed in the same manner as in step 207 of FIG. Next,
In step 702, the pot type is determined. Pot type discrimination is balanced
Temperature TH ₀ Is 109 ° C. or more. 1
If the temperature is 09 ° C., the process proceeds to step 703, where the temperature is less than 109 ° C.
If so, the process proceeds to step 704. Proceed to step 703
If the pot type is a pot of high thermal conductivity material (for example,
Aluminum) and proceeds to step 704
If the pot type is a pot with low thermal conductivity (holo, stainless steel)
Less). Hereinafter, proceed to step 703.
Will be described, but proceeded to step 704.
In case, the numerical value in the control after step 703 is changed
Is done. At step 705, the thermal power / cooking amount determination is performed.
It is. The determination of the heating power / cooking amount is shown in FIG.
This is performed by the determination unit 175. The heating power / cooked rice amount determination unit 175 determines whether
Temperature sensor 107, timer 151, temperature equilibrium state determination
The equilibrium temperature detecting section 161 of the constant section 153 and the determining section 149
Contains. The way of discrimination is simply described as ignition
After starting the heating of the pan, then the equilibrium temperature TH₀ To
Time until detection ΔT₀ Time is less than 320 seconds
It depends on whether or not. That is, the temperature sensor 107 is connected to the standard burner 1
The temperature of the pan heated at 03 was measured and measured
Equilibrium temperature detector of temperature equilibrium state determiner 153 from data
161 detects and detects the equilibrium temperature of the pan. Soshi
Therefore, the timer 151 determines that the ignition confirmer 141a has confirmed ignition.
Measure the elapsed time from the point in time when the
It is sent to the determination unit 149. As a result, the determination unit 149
Can obtain data on the elapsed time to the equilibrium temperature of the pan
Yes, determine if the data is less than 320 seconds
By doing so, it is possible to determine the magnitude of thermal power and the amount of rice cooked.
You. Here, the reference thermal power is indicated by the thick line 1 as described above.
It is cooked rice power corresponding to 23, about 1,300 kcal
/ H. The reference rice cooking amount is one. So
To determine the equilibrium temperature from ignition to equilibrium temperature detection.
Time ΔT₀ Is less than 320 seconds, step 7
Go to 06, the thermal power is large, the amount of cooked rice is judged to be 1 go
You. This is because the amount of cooked rice is judged to be smaller than this.
The rise time is short, so the thermal power is large.
This is because you will be doing something wrong. In contrast, the point
Time ΔT from fire to equilibrium temperature detection₀ Is more than 320 seconds
If so, proceed to step 707, where the thermal power is small or young
Indicates that the amount of cooked rice is two or three. This
Like, after ignition (beginning the heating of the pot)
ΔT until degree detection₀ The amount of heat and rice cooked according to the value of
Then, the following different control is performed. In addition, point
Time ΔT from fire to equilibrium temperature detection₀ Thermal power by the value of
-The amount of cooked rice is determined, but the first before the equilibrium temperature is detected.
Temperature rise from the temperature of the sample to the second temperature before detection of the equilibrium temperature
The amount of heat and rice cooked according to the amount of time required
May be different. That is, the first temperature is the temperature of water at the time of ignition.
If the second temperature is regarded as the equilibrium temperature,
Measuring the time until equilibrium temperature detection is an essential difference
Absent. The elapsed time from ignition to equilibrium temperature detection,
From the first temperature before the equilibrium temperature detection to the second temperature before the equilibrium temperature detection
Depending on the time required to raise the temperature to the temperature,
Not only when determining the amount, but also at the predetermined temperature before detecting the equilibrium temperature.
Depending on the time required from the temperature to the detection of the equilibrium temperature,
The determination of the amount of cooked rice may be performed. Next, steps 706 to 708
If the process proceeds to the equilibrium temperature TH₀60 seconds after detection
Loop processing is performed until the processing is completed. Then, as shown in FIG.
Proceed to step 709 and switch to low heat after 60 seconds
You. The low heat here is about 350 kcal / h. This
In contrast, the process proceeds from step 707 to step 718.
In this case, loop processing is performed for 90 seconds after equilibrium temperature detection
After 90 seconds, as shown in step 719 in FIG.
Switch to low heat. Thus, in step 708,
A loop process for 60 seconds is performed, and in step 718, 9
Loop processing is performed for 0 seconds.
Switched to low heat with short elapsed time after temperature detection
I have. This means that if the firepower is large, spills are likely to occur.
The burner will be extinguished
Switch to low heat early to prevent
This is to prevent this. Also, the more rice cooked, the more balanced
It switched to low heat late after temperature detection. This is cooking
As the amount of rice increases, the temperature sensor 107 detects the equilibrium temperature.
Time until the temperature of the rice in the pot reaches the boiling temperature
This is because the delay width tends to be widened. This
Equilibrium temperature is detected when the amount of cooked rice is large considering the tendency
To increase the time until switching to low heat
Switch to low heat when rice temperature is boiling
I have to. The reason for switching to a boiling state is
When boiling on the side to be controlled, to ensure the absorption of rice
This is to match the interval with the actual boiling time. More than
Thus, according to the result of the discrimination between the heating power and the amount of cooked rice in step 705,
If the thermal power is large, turn off the heat soon after detecting the equilibrium temperature.
Change to a low heat after the equilibrium temperature is detected if the amount of cooked rice is large.
Switching is performed so that each adverse effect does not occur. Next
In step 709, the process proceeds to step 710, where
The degree of variation is determined. The criteria for this determination
Data is also ΔT₀ From this ignition, the equilibrium temperature TH₀ Inspection
Time to knowledge ΔT₀ Is greater than 170 seconds
Thus, the degree of variation of the thermal power is determined. Thermal power dispersion
If it is, the degree of departure from the display line 123 written as rice cooking is considered.
To taste. In order to correct such variations,
Elapsed time until equilibrium temperature detection ΔT₀ Is less than 270 seconds
If not, proceed to step 711 and determine that the thermal power is greater.
If it is longer than 270 seconds, the process proceeds to step 713,
The thermal power is judged to be somewhat large. As a result, step 7
If the process proceeds to step 11, the process proceeds to step 712, and 270 seconds
When the loop process is performed and the process proceeds to step 713
In step 714, a loop process for 150 seconds
It is done, and it switches to high heat which is rice cooking power in step 715
Cook over low heat until you get it. On the other hand, FIG.
When the process proceeds from step 719 to step 720,
A loop process is performed, and in step 721, it is cooked rice power.
Low heat rice cooking is performed until switching to high heat. like this
In the case of small heat and large amount of cooked rice (2 go to 3 go)
Is a low-heat rice cooker for 200 seconds and has a large heat power
If the amount is low, cook for 150 seconds (270 seconds)
Has been done. Hereinafter, steps 712, 714 and
And what can be learned from step 720 will be described. S
From Step 712 and Step 714, use the same amount of cooked rice
If there is more heat, low heat cooking time will be secured for a long time
You can see that it is. This means that the firepower is large
Because the rise time to the equilibrium temperature is fast,
Means that the water absorption time in the
Prevent from rising from equilibrium temperature, low heat rice cooking time
To take a long time to absorb water sufficiently
It is. In contrast, steps 714 and 72
It can be seen from 0 that if the thermal power is the same,
The longer the amount of rice, the longer the time of low heat cooking rice
That is. This means that there is a lot of rice cooked
Because the amount of cooked rice that must be absorbed
Prevents standing up from a low temperature, low heat cooking for a long time
This is because it is necessary to secure meal time. In terms of results,
The greater the thermal power, the greater the amount of cooked rice
It can be said that low heat cooking time is secured for a long time. This
With such a control, the rice is fully absorbed,
I try to cook delicious rice that does not exist. In addition, weak
To secure the time for cooking rice after reaching the equilibrium temperature, simply cook
The temperature in the pot rises compared to when cooking rice with rice fired power
It is hard to peel and can keep the boiling state for a long time,
This can improve the water absorption effect.
You. Next, when the process proceeds to step 716 in FIG.
Whether the sensor temperature TH of the temperature sensor 107 is 145 ° C. or more
The loop processing is performed until 145 ° C or more.
You. As a result, until the rice cooked by the rice cooker reaches 145 ° C.
Done in This temperature is a temperature that indicates that moisture has evaporated.
And heating the pot to about 145 ° C.
This is to cook delicious rice. And it reaches 145 ° C
After that, the routine proceeds to step 717, where the temperature is switched to low heat.
Step 722 of the process of step 721 and step
For step 723, step 722 is step 7
Step 723 is the same as step 16
7, the description is omitted. Next, steps 712 to FIG.
Proceed to step 724 and wait 90 seconds after switching to low heat.
Loop processing is performed. As a result, low heat cooking for 90 seconds
Meal is done. Then, in step 725, the cooked rice amount determination 1
Is performed. This cooked rice amount determination 1 is performed by the temperature sensor 107.
Performed depending on whether the measurement temperature TH is higher than 138 ° C
It is. That is, after 90 seconds have passed since switching to low heat, the temperature
The amount of cooked rice is determined based on the value of the temperature measured by the sensor 107.
Measurement temperature TH of temperature sensor 107 is lower than 138 ° C.
If not, proceed to step 726.
Goes to step 727. Step 727: Cooking rice
Step 728 is a step of switching to power (high heat).
, A 10-second loop process is performed, and rice is cooked with rice cooked
For 10 seconds. And cook rice for 10 seconds
Doing so will eventually drive off excess water
is there. Then, in step 729, the fire is extinguished and thereafter extinguished.
Steaming after the fire takes place. As shown in step 730
Like, steaming after fire extinguishing is secured for at least 180 seconds
Have been. If 180 seconds have passed after the extinguishing, step 7
It is determined whether or not the elapsed time since ignition at 31 is 20 minutes.
If 20 minutes have passed, cooking is completed and the buzzer
Sounds. Step 7 if 20 minutes have not elapsed
Proceed to step 32, and loop processing is performed until 90 seconds have elapsed.
It is. According to steps 731 and 732, the ignition
If the elapsed time has reached 20 minutes, or 2
When the time has not reached 0 minutes but 270 seconds have passed since the fire was extinguished
Cooking is completed. In other words, the steaming time after the fire is extinguished
180 seconds is always secured by Step 730 and 90 seconds
20 minutes after ignition of the second extension
Is controlled so that the steaming time after fire extinguishing is added
I have. This control is performed in step 716.
If the rice cooking time is shortened during the process up to
With the shortening of the heat time, the evaporation of water and the
Since the time is short, adjust it with the steaming time after the fire is extinguished
It is to guarantee the taste. On the other hand, steps 723 to FIG.
When the process proceeds to step 733, the process is the same as step 724.
Therefore, the description is omitted. Similarly, step 734 is a step
This is the same process as step 725, and a description thereof will be omitted. However
The processing up to step 734 determines that the amount of cooked rice is large.
If the process proceeds to step 727,
This means that the determination of the amount of rice has been corrected. That is,
The judgment result of step 707 means that the thermal power tends to be small
It means that the amount of cooked rice is large, but the thermal power is small
And always satisfy both conditions, that is, a large amount of cooked rice
If not, for example, the heating power is extremely small,
May be included, and in this case,
This is a process for correction. After proceeding to step 727
Is processing when the amount of cooked rice is one, and is the same.
Therefore, the description is omitted. Next, at step 734, the temperature sensor
When the measured temperature TH of the heater 107 is lower than 138 ° C.
Proceeds to step 735, where rice cooked amount determination 2 is performed.
This cooked rice amount determination 2 is a process of determining whether two or three go.
The data used for determination is the same as in step 734.
Sensor 90 seconds after switching to low heat
Is the sensor temperature. The reference value is 130 ° C.
Step if the sensor temperature TH is lower than 130 ° C
Proceed to 736, and if it is 130 ° C. or higher, step 737
Proceed to. Step 736 performs a loop process for 30 seconds
Step 737 is a loop processing for 60 seconds.
This is the logical step. Here, step 736 is for cooking rice
Step 737 corresponds to the case where the amount is 2 go, and the amount of cooked rice is 3
The case is supported. You can see from the processing so far
If the amount of cooked rice is one, switch to low heat
Cooking time is 90 seconds, and in the case of 2 go, it is 120 seconds
In the case of 3 cases, the time is 150 seconds. Like this, cook rice
The larger the amount, the longer the cooking time on low heat is secured
This is because the greater the amount of cooked rice, the less likely it is to burn. Soshi
And secure a low heat cooking time according to the amount of cooked rice
And cook delicious rice. Next, returning to step 726, step
If the process proceeds to 726, the temperature sensor 10
7 was determined to be lower than 138 ° C.
In this case, it is determined that the amount of cooked rice is 2 or 3
Was modified from the process determined to be
In order to cook rice for 90 seconds,
I have. Comparing steps 736 and 737,
There is a tendency for rice cooking time on low heat to be longer,
Means that the amount of heating up to that point is
Water evaporation may not be sufficient.
You. Steaming is done with low heat cooked rice as described above.
In step 738, to indicate that the
Is switched to high heat, and in step 739,
Cooked rice is cooked and the fire is extinguished in step 740. Step
Steps 738 through 740 follow steps 727 through
This is the same processing as step 729. Fire extinguishing at step 740
After that, a loop process is performed for 270 seconds in step 741.
270 seconds after the fire was extinguished
And rice cooking is completed. Here, in step 741, 2
A steaming time of 70 seconds is always ensured, step 73
0, different from the processing in steps 731 and 732
Let me. This is the cooking time for 2 go or 3 go
Steam after extinguishing to prioritize taste over prioritizing
In case of one go rice cooker while enough time is secured
To cook rice in 20 minutes after ignition, giving priority to cooking time
This is the result of giving priority to performing the operation. As shown in FIG.
