It is composed of a pair 21.

The same applies to the upper and lower burners on the right side, so the same reference numerals are given and their description is omitted.

The grill burner 37, which is a generic term for these, is a gas control block 2 whose opening and closing is controlled by a control circuit 24.

Gas is supplied to each grill burner through a nozzle 32-3 and a lower burner right nozzle 32-4.

The child lock switch 1 having the above structure
When it is confirmed that 9 is OFF and the ignition button 8 is turned ON, the control circuit 24 is powered on, and the control of the control circuit 24 moves the grill gas control unit 31 to the ignition position to open the original solenoid valve 27. Then, the grill burner 37 is ignited by the ignition plug 21.

The temperature detected by the temperature sensor 4a for measuring the temperature inside the grill and the temperature detected by the thermocouple 38 are input to the control circuit 24. Based on this input data and the setting input from the operation panel 5. The grill flow rate control unit 31
It is possible to adjust the flow rate of the gas supplied to the grill burner 37 by controlling the driving of the heating unit, and to adjust the heat power by automatic control.

As can be seen from the above structure, the left stove 1,
The control circuit 24 controls the combustion state of each combustion section including the right stove 3 and the grill 4.

3 (a) and 3 (b) are views showing a gas control block 25 of the gas cooker according to the present invention. Gas flows from the hose end 26, the original solenoid valve 27, and the gas control unit 29 of each burner. , Go to 30, 31. The gas that has entered the gas control unit of each burner enters from the cock body 33-1 of the flow rate control unit 33, passes through the flow rate control plate 33-2 and the slide closure 33-3, and the gas outlet 33 of the cock body 33-1.
-4 and go to the gas pipe 42 leading to the nozzle.

Further, the flow rate control plate 33-2, together with the slide closure 33-3, includes a spring 33-5 and a cock body 33-.
The pressure is set to 1 to set the gas sealing pressure. Further, one end of a drive connecting shaft 33-6 for driving a slide is fitted to the slide closure 33-3, and the other end is connected to the drive connecting portion 34-1 of the stepping motor 34.
Further, the drive connecting shaft 33-6 has a pin 34-2, and the pin 34-2 is joined to the movable portion of the encoder 35 (position detecting means) fixed to the cock body 33-1 to drive the same. The moving state of the connecting shaft 33-6 is transmitted to the encoder 35 to detect the position. Also,
An O-ring 33-7 is used between the drive connecting shaft 33-6 and the cock body 33-1 for gas sealing. The encoder 35 is a lead wire 35-1, the original solenoid valve 27 is a lead wire 27-1, and the motor 34 is a lead wire 3.
It is connected to the control circuit 24 via 4-2.

The motor 34 has a screw portion 49 on its shaft portion as shown in FIGS.
9 is provided with a female screw 50, and the drive connecting shaft 33-6 is fixed to the tip of the female screw 50 to drive the connecting portion 34-1.
Are configured. Therefore, when one drive pulse is sent to the stepping motor 34, the stepping motor 34 rotates by one pole, the screw portion 49 also rotates by that amount, and the female screw 50 moves by that amount. As an example for reference, assuming that the number of poles of the motor is 24 and the lead of the screw is 2 mm, one pulse moves 2/24 = 0.08 mm.

Therefore, when the stepping motor 34 is rotated, the drive connecting portion 34-1 is linearly moved, the drive connecting shaft 33-6 is moved, and the slide closing fitting at the tip of the drive connecting shaft 33-6 is performed. The child 33-3 moves. On the other hand, since the flow rate control plate 33-2 is fixed, the slide closure 3
As shown in FIGS. 6c to f, the through hole 33a provided in the center of 3-3, which serves as a gas passage adjusting unit, is sequentially aligned with the hole position serving as the gas flow rate adjusting unit of the gas flow rate control plate 33-2. Adjust the gas flow rate. Due to the above-mentioned configuration, the torque of the stepping motor 34 is set by the spring 33-5 for urging the slide closure 33-3 and the drive connecting shaft 33-.
The load of the O-ring 33-7 for gas seal of No. 6 and the thrust load for driving the encoder 35 become
The load of -5 is perpendicular to the slide closure 33-3 and is always a constant load in the sliding direction, and the load itself is small. Further, since the flow rate adjustment control method is determined by the overlapping state of the through holes of the flow rate control plate 33-2 and the slide closure 33-3, the flow rate adjustment accuracy at each thermal power switching stage is much higher than that of the needle system. Improve to.

Only when it is necessary to adjust the flow rate of gas,
Since it is a system that drives a motor, it usually does not operate, can save power, and is compatible with battery power.

However, even if it is a needle type, each content described below can be implemented and is not applicable only to the slide closure.

5A to 5C show an encoder 35.
3 is an external view of FIG. As described above with reference to FIGS. 3A and 3B, the pin 34 is perpendicular to the drive connecting shaft 33-6.
-2 is provided, and the encoder 35 detects the movement amount of the pin 34-2. The encoder 3
Reference numeral 5 denotes a substrate 35-1 on which a pattern is largely printed, an outer shell 35-2 forming an outer shell, and a slide body 35 for sliding the substrate.
-3 and a lead wire 35-4 for taking out a signal from the substrate, the sliding body 35-3 is provided with a current collector 35-5 matching the pattern.

6A to 6F show an encoder 35.
It is a diagram showing the correlation between the pattern and the thermal power and the number of pulses, and there are five-stage thermal power switching positions of a closed position, a low heat position, a medium weak position, a medium heat position, a medium strong position, and a strong position. This is a configuration in which both stepping pulses are used for detection (here, 5 steps of thermal power adjustment will be described, but 3 points of thermal power can be obtained by taking points D and E for 3 steps). Described as a multi-stage description).

At point A, track 1 is ON (track 4 (+
COM) and track 1 are electrically connected by current collection), and tracks 2 and 3 are OFF. Track 4
(+ COM) is a common power supply pattern. This state shows a closed state in which gas is shut off (gas does not flow because the through hole 33a of the slide closure 33-3 is not connected to the hole 33b of the flow rate control plate 33-2).

From a safety point of view, in this state, only the track 1 is in the ON state, and it is possible to detect whether the lead wire is broken, short-circuited (track 1 is ON.
Others must not be turned on at. When the track 1 is broken, the closed position disappears and the original solenoid valve is shut off. At this position, the movement pulse of the stepping motor 34 is set to 0, and a pulse counter (described later) is also reset to 0.

In zone B, tracks 1, 2, 3 are both O
The FF state represents the transition stage from the gas cutoff state to the valve open state. In the transition stage, even if each of the tracks is in the OFF state and the pulse counter has a predetermined number of pulses, it is an abnormal state in which the predetermined position is not reached, for example, when the drive unit is fixed and the stepping motor 34 does not rotate. Considering the safety, the configuration is such that it can be recognized.

Point C is a weak position in which tracks 1 and 2 are off and tracks 3 and are on. Flow rate control plate 33-2
The gas flows in from one of the smallest hole positions, and is supplied to the nozzle 32 through the gas pipe 42 (the state of low heat power is shown in FIG.
As shown in FIG.
3) A small hole in 3-2 hangs over and a minimum flow of bake flows.)

The drive pulse of the stepping motor 34 starting from the point A has a moving distance of 3.58 / moving amount per pulse of 0.08 mm = 45 pulses. Especially regarding the minimum position, if it moves to the closing side from this position, it will be in a closed state once and the supply of gas will be interrupted, and if it is moved in the opening direction again, raw gas will come out, so the minimum position detection is Both the pulse counter number and the encoder 35 are checked to ensure safety.

Point D is track 1, OFF, track 2,
When it is 3 and ON, it shows the middle low heat position. At the medium-low heat position, gas flows in from the two hole positions of the flow burning control plate 33-2 and is supplied to the nozzle 32 via the gas pipe 42. Also,
The drive pulse of the stepping motor 34 starting from point A has a movement distance of 5.2 / movement amount of 0.08 per pulse.
mm = 65 pulses.

Regarding the safety, it is between the minimum thermal power position and the maximum thermal power position, and the need for double confirmation is alleviated, but the position is detected by both the encoder 35 and the pulse counter. For example, the position can be reliably detected even when the pulse counter malfunctions due to the influence of noise, and the usability is improved accordingly.

Point E is track 1, OFF, track 2,
ON, when the truck 3 is switched from ON to OFF, the medium heat position is shown. At the medium heat position, gas flows in from the three hole positions of the flow rate control plate 33-2 and is supplied to the nozzle 32 via the gas pipe 42 as shown in FIG. Also, starting from point A, the stepping motor 34
The drive pulse of is a moving distance of 6.7 / moving amount per pulse of 0.08 mm = the number of pulses 84.

Therefore, the position can be confirmed by both the pulse counter number and the encoder 35 as at the point D.

Point F indicates tracks 1 and 3, OFF, and track 2 ON, and indicates a medium high flame position. At the medium-high heat position, gas flows in from the four hole positions of the flow rate control plate 33-2 and is supplied to the nozzle 32 via the gas pipe 42. The drive pulse of the stepping motor 34 starting from point A has a moving distance of 8.2 / moving amount of 0.08 m per pulse.
m = the number of pulses 102.

In this case, the pattern position of the encoder 35 is not determined and is managed only by pulse management.

The position of point F does not match the pattern of the encoder 35, and the position is determined by the numerical value of the pulse counter. The reason is that the pattern of the encoder 35 is saved and the cost is reduced. However, since it is easy to perform all the positions by the encoder 35 as an explanation of one embodiment, this F point is set by the encoder 35. Some examples of disagreement are given. Particularly regarding safety, the combustion power is adjusted in the range between the minimum position and the maximum position and the combustion state is secured, and some fluctuations in the pulse counter are harmless to the safety. Further, with respect to the accuracy of position detection, the number of pulses from the front and rear positions is small, and it is possible to perform the software processing because errors can not be accumulated.

At point G, track 1 is off, track 2 is
3 is ON, indicating a high heat position. At the high-fire position, as shown in (e) of the figure, gas flows in from the maximum hole of the flow rate control plate 33-2 and is supplied to the nozzle 32 via the gas pipe 42. Also, starting from point A, the stepping motor 34
The driving pulse of is a moving distance of 11.4 / moving amount per pulse of 0.08 mm = pulse number 143.

The position of the maximum thermal power position is detected by double detection by the encoder 35 and the pulse counter. Moving beyond the maximum position will result in adding an unreasonable load other than normal use to the gas flow control mechanism,
It is also necessary for the purpose of preventing the reliability of the mechanism from decreasing.

Although the above description has been made in detail regarding the five-step thermal power control, when the grill is to be controlled in three steps, for example, the points D and F can be easily changed by killing them with microcomputer software. Yes, it has the convenience of being able to deal with it by changing only the hole diameter of the flow rate tip to the required heat power hole diameter (no need to change the encoder and flow rate control mechanism).

FIG. 7 (a) is a view showing a cross-sectional view of the grill. A pair of upper and lower burners 37-1, 37- is arranged on the left and right sides, respectively.
2, 37-3, 37-4, upper burners 37-1, 2
The heat of combustion is reflected from the gap A between the outer grill body 51 and the inner grill body 52 to the ceiling of the outer grill body 51 to heat the upper surface of the fish to be baked. On the other hand, the lower burners 37-3 and 4 rectify the air by the partition plate 53 and heat the back surface of the fish of the wire mesh 54 to be burned. As a result of the above, the upper and lower surfaces of the fish are simultaneously cooked. Further, the burner cover 55 has a role of preventing the oil of the fish from splashing on the burner to cause clogging of the burner and ignition of the oil. The supply air of the upper and lower burners is separated for the upper and lower burners by the left and right partition plates 53 and is supplied to the burner as secondary air, and the exhaust air of the upper and lower burners is exhausted from the grill exhaust hole 55 provided at the back.

FIG. 7B is a longitudinal sectional view showing a grill door 56 on the front side, a grill plate 57 fixed to the grill door, a wire net 54 placed on the plate 57, and lower burners 37-3, 37-.
4. There is a grill exhaust hole 55 on the back side, and the exhaust gas discharged from the exhaust hole 55 is exhausted from two exhaust passages of an exhaust portion 58 having a double structure.

That is, as shown in FIG. 8 (a), the exhaust portion 58 includes a grill exhaust inner metal fitting 59 and a grill exhaust outer metal fitting 59-.
1 is a sensor flue 58a formed by inner and outer metal fittings for grille exhaust, and a grille flue 58b formed by the outer shell 51 of the grille and the outer metal fitting 59-1 for grille exhaust.
That is, two exhaust passages are formed. Also,
A sensor flue port 60 is provided on the grille exhaust metal fitting 59, and the flue port 60 is located at the center of the left and right lower burners 37-3, 4 and below the wire net 54. A temperature sensor 4a for measuring the temperature inside the grill is attached to the lower part of the grill exhaust metal fitting 59-1. For the purpose of measuring the exhaust gas temperature of the sensor flue port 60, the position where the exhaust gas temperature flowing from the exhaust flue port is appropriately measured is set by an experiment. And the grill exhaust outer metal fitting 59-1
The slit 59a having a width W and a slit width T is provided above the temperature sensor 4a. With this slit 59a, it is possible to block the heat transfer from above and create an atmosphere in which the characteristics of the fish can be grasped more accurately.

FIG. 9 is a diagram showing the sensor temperature and time when the horse mackerel is baked. The vertical axis represents the temperature and the horizontal axis represents the time after ignition. The empty grill without load, raw horse mackerel 180g1
It is each temperature curve at the time of grilling 180g of raw horse mackerel and 3 dogs simultaneously. However, the thermal power is 2200 kcal / h
It is when baked with (maximum firepower). One horse mackerel is 8 after ignition
It is ready to eat in minutes, and 3 horse mackerels are ready to eat in 11 minutes after ignition.

If the time required to reach 100 ° C. is measured, it takes X1 second in the case of the sky, X2 second in the case of one horse mackerel, and X3 seconds in the case of three horse mackerel, which takes a long time in proportion to the weight.
Therefore, if there is a correlation between X2 seconds and 8 minutes for one horse mackerel, and 11 minutes for X3 seconds and three horse mackerels, X is measured to estimate the baking time and automatically extinguish the fish. You will be able to In automating the grill, the time proportional to the weight can be accurately measured, and by setting the baking time in proportion to the weight, proper baking can be completed. However, although the baking time varies depending on the type of fish and the processing method, the description will be limited to the baking state of the horse mackerel.

In this case, the biggest problem is as follows.

(1) The temperature of the temperature sensor can always accurately measure the temperature information of the fish (2) As much as possible, the difference between empty, one and three fish is large (3) Variation between instruments (gas species exchange) (4) Secular change (characteristic does not change due to dirt on equipment) FIG. 10 is a diagram showing the temperature of exhaust gas in the vicinity of the exhaust port. The temperature information of the fish is at the center of the right and left burners of the exhaust port and the bottom of the wire mesh. If it is lowered too much, the atmospheric temperature of the dish is measured and the temperature information of the fish cannot be obtained. Specifically, when the sensor temperature reaches 100 ° C, the upper point A of the exhaust port is 4
00 ° C, 280 ° C at the center point B, 150 at the upper part of the sensor
Since the temperature is 110 ° C and the vicinity of the sensor is 110 ° C, the measurable range is limited. Also, since the air convection is measured, it is easily affected by the position of the fish with respect to the wire mesh.
It will also change depending on whether you approach the door or plunge into the back.

In order to solve these problems, the double flue is the most effective one, that is, it accurately takes out the atmospheric temperature of the fish in the exhaust gas, and only the portion where the temperature characteristic of the fish under the wire mesh appears is the flue. With the draft effect of, the flow is created and taken out. At the same time, the action made it possible to absorb variations between the instruments. Also, regarding the problem, if you do not have a double flue,
Exhaust heat from the upper part of the flue is conducted to the sensor part by heat conduction, and the time difference between the number of animals is reduced, but this is also eliminated. Of course, the slit for blocking heat conduction at the upper part of the sensor mounting also has a great effect, but it has a double flue effect.

On the other hand, for the surface treatment of the flue, a white hot-dip aluminized steel sheet was used as the material, but the temperature characteristics of the initial fish and the temperature characteristics after the repeated experiment were significantly different, and after the repeated experiment. The temperature characteristics of the fish became the same for 1 and 3 fish.

The cause is due to blackening due to dirt on the flue,
It is to increase the temperature of the temperature sensor independent of the fish information by increasing the blackbody absorption of heat in the flue and conducting heat. Therefore, stable condition information of the fish temperature cannot be obtained unless a condition in which the characteristics change progresses is created by creating a deteriorated state from the time of new product. Although the accuracy of this determination is somewhat reduced, the quality can be sufficiently secured as compared with the case that the accuracy changes over time.

Therefore, it is indispensable to blacken the components of the flue including the sensor mounting portion to ensure reliability due to aging.

The left stove drive determination unit 69 determines the cooking mode determination unit 9 for determining the cooking mode via the temperature determination unit 92 for determining the temperature data input from the temperature sensor 1.
3 has a burnt mode determination unit 9 according to the cooking mode
4. It has an overheat prevention determination unit 95. The grill drive determination unit 71 is a cooking mode determination unit that determines the setting of the fish species mode input from the operation unit via the temperature determination unit 92-1 that determines the temperature of the temperature data input from the temperature sensor 4a. 93-1, a burn mark determination unit 93-2 that determines the setting of the burn mode, and a burn-up determination unit 93- that performs burn-up determination.
3. A manual overheat prevention determination unit 93-4 and an automatic overheat prevention determination unit 93-5 are included.

The left, right stove, and grill drive determination units 69, 70, and 71 perform combustion monitoring based on the temperature detection data input from the thermocouple 38, and at the same time, count data of the elapsed time from ignition by the timer. On the basis of the above, the control for closing the gas control units 29, 30, 31 of the left, right stove or grill is performed in an emergency situation such as disappearing or forgetting to erase.

A method of controlling the gas cooker by the control circuit 24 having the above structure will be described with reference to the flow chart shown below. In addition, S1 shown in each flowchart,
S2 ... is a step number indicating the processing procedure, and coincides with the number added to the text.

First, FIG. 12 shows a key input state of ignition and extinguishing operations.
If the child lock 19 is OFF, it is S1 (a state where various operation keys are accepted), and if the ignition key is pressed for 0.3 seconds or more, S2, it is determined that there is a key input, and the left stove S
3, the right stove S4 and the grill S5 are confirmed, the corresponding combustion unit is stored, and then S6, and it is determined whether or not the corresponding combustion unit is in use. When the corresponding combustion unit is in use, the total operating means 74 is instructed that it is a fire extinguishing operation and that it has priority 1, S8, erases the memory of the applicable stove, and presses the same key continuously for a predetermined time or longer. Whether or not it is determined in S10. If the key is pressed, the failure determining means 89 is instructed that the ignition key has a failure (S11). If the combustion unit is not in use, S7 is instructed to the general operating means 74 that it is an ignition operation and the priority is S2, and if the same key is continuously pressed for a predetermined time or more, S10. To judge. When pressed, the S11 configuration is used to instruct the failure determination means 89 that the ignition key has a failure.

Here, the meaning of setting the priority and operating the motor is that in the case of a battery power source, if a large load is applied at one time, an extreme voltage drop will occur and the voltage of the microcomputer will also drop and stop. In order to prevent this, consider not to rotate multiple motors at the same time. In that case, priority is set according to the use event from safety and usability. Priority 1 is extinguishing operation, priority 2 is ignition operation, priority is Degree 3 is a manual fire power adjustment operation, and priority 4 is an automatic fire power adjustment operation.

Further, the consideration of the continuous pressing of the ignition key is a means for avoiding a dangerous state in which the switch is turned on without permission such as a water drop entering the key, an object pressing the key, etc. A safety timer is also provided for the firepower adjustment key with the same meaning.

FIG. 13 shows an example of a key input method for simple 5-step thermal power control.

In FIG. 13, the key input judging means 82
Decides whether the stove is in use, S13, and if it is in use, determines whether the fire power adjustment key input is 0.1 seconds or more, S14, and in that case, the left stove S15, the right stove S16, the grill or S17. Judgment is made, the corresponding combustion unit is stored, S18, the thermal power is judged to be UP or S19, DOWN or S20, and the general operating means 74 is instructed together with the priority level S21, and the same key is continuously pressed for a predetermined time or longer. Whether or not there is S22 is determined. If the key is pressed, the S23 configuration is used to instruct the failure determination means 89 that the thermal power key has a failure.

FIG. 14 shows the contents of the key input judging means 82 for the various cooking mode keys for the grill in the operating section 5. When the cooking mode key is pressed S
24, it is determined whether the grill is in use S25, otherwise the timer is turned ON and S26, the cooking mode key is accepted and 1
It is determined whether or not a minute or more has elapsed, S27, and if not elapsed, it is returned to the original state, and if it has elapsed, the cooking mode is reset S2.
8. When the grill is in use, the cooking mode is O
If it is N, it is determined S29, and if not, it is 1 after the ignition of the grill.
It is determined whether it is within 0 seconds, S30, and if 10 seconds or more have elapsed, the cooking mode is reset S28. If it is within 10 seconds after the grill is lit, it is determined whether the cooking mode is ON or not. S3
0, increment the counter N = N + 1, S31, N
Is not 1 and N <> 1 is determined, and in the case of S32 and 1, the cooking mode is determined to be "raw / appearance", S33, the "raw / appearance" lamp is turned on, S34, and the process proceeds to the next stage S41. If not, N <> 2 is determined whether N is 2 or not, and in the case of S35 and 2, the cooking mode is determined to be "fillet", S36, the "fillet" lamp is lit, S37, and the process proceeds to the next stage S41. Otherwise, since N is 3, the cooking mode is determined to be "dried fish", and the lamp of "dried fish" is turned on in S39, S40, the counter is set to 0, and N = 0, S41, and the process proceeds to the next stage S42. Then, in the next stage S42, an instruction is given to the grill drive determination unit via the drive control unit 68 to restore the original state.

FIG. 15 is a diagram for handling the key input of the dark spot of the cooking setting means. Burning key input continues 0.1
It is determined whether or not there is a second or more in S43, and if there is, it is determined whether the cooking mode key is ON or not. S44, if it is not ON, it is returned to the original state.
+1, S45, N <> 1 is determined, and if S46 and N are 1, strong charring is set to S47, the charring strength lamp is turned on, and S4 is set.
8. Put back. On the other hand, if N is not 1, it is judged whether N is 2 or not.
50, the non-burning lamp is turned on, and S51 is restored. If it is not 2, the counter is set to 0, N = 0, S52, set to scorching, S53, the scorching lamp is turned on, S54, the grill drive determination section is instructed via the drive control section, S55, and S56 is restored. .

The above contents are an example of the concrete contents of the key input judging means.

Next, the contents of the total operating means 74 of the next stage through the above key input judging means will be described below.

FIG. 16 shows the operation of the total operating means 74.
First, it is determined whether or not there is an ignition key input in S57, and the voltage determination means 91 determines whether the voltage of the voltage detection means 67 is 3.2 V or less in S58. The determination S59 is made, and in the above case, the inspection execution mode is set to the inspection mode determination means 87 S60. The inspection mode determination means 87 is omitted.

Next, it is determined whether the cooking mode is instructed or not, S6
1. If it is a cooking mode instruction, the contents are instructed to the cooking mode determination unit of the grill drive determination device S62. If it is not the cooking mode instruction, S61 is determined, and it is determined whether the ignition instruction is issued, S6.
3. In the case of the ignition instruction, it is determined whether or not the other combustion portion is used, S67. When the other combustion portion is not used, a drive instruction is given to the corresponding combustion portion, S68, and then the original solenoid valve 27 is opened. Then, S69 and S70 for outputting the igniter output.

If it is not an ignition instruction, it is S63, if it is a fire extinguishing instruction or a thermal power change instruction, it is S64, and it is judged whether another motor is rotating or not. S65 if other motors are rotating, it is determined whether the priority of rotation is faster than the priority of the corresponding combustion section, S66. If it is earlier, the rotating motor is stopped and the combustion section of the corresponding combustion section is stopped. To drive to S7
1. Otherwise, in S66, the drive of the corresponding combustion unit is evacuated, the rotation completion is waited, and after the stop, the drive of the corresponding combustion unit is instructed S71. If no other motor is driving S65,
S73 instructing the corresponding combustion unit to drive.

17 to 19 show the contents of the drive determination unit of the combustion unit, which operates according to the instruction from the general operating means 74. First, in FIG. 17, the state of the encoder 35 is read by the position determination means 100 (correlation table shown in FIG. 6) and set as the current position S75, it is determined whether it is a closing instruction S76, and if it is a closing instruction, the closing position is confirmed S77, When not in the closed position (when the encoder position is not 100)
Goes to the motor error SUB at S78, and returns to S76 at the closed position.

If it is not a closing instruction, S76, it is judged whether it is an ignition instruction or not, S79. In that case, the timer for preventing forgetting to turn off is turned on, S80, the target position of the thermal power is set to a medium and strong position and the number of pulses is set to 102, and the speed is set to S81. Is set to a high speed to instruct the rotation direction to be a strong direction in S82, and the lamp is instructed to be in a strong mode in S83. After that, a pulse is output through the motor IC through the power saving determination unit S84 and the motor speed control unit S85 in the drive control unit S86, and the number of pulses output to the motor by rotating the motor is counted by the counter. N = N + 1 "S87. When the count number of the pulse counter becomes "20 count <N" S
88, check if the encoder position is in zone B "000" S89, if not, "Motor error SU
B "S90 (separate description), and if so, it is determined whether the pulse counter has reached" 102-M <N ", which is before the M pulses of 102 pulses at the medium and strong position, which is the target position, at S91. Only in the case where the encoder 35 is the target position, it is determined whether or not the medium / strong position is “010” in S92. If the encoder 35 is not the target position, the value N of the pulse counter is M and the number of pulses 102 at the medium / strong position is added with M. Whether or not the value is greater than or equal to the value is determined by "102 + M <N" S93, and if not, the process returns to S84, and if so, jumps to the motor error SUB S94 (motor error SUB will be described later).

On the other hand, if the encoder position becomes the target medium-strong position S92, the number of pulses is set as the reference medium-strong pulse number (1
02) to S95, and turn on the igniter as shown in FIG.
Instruct S96, to determine that the burner has ignited. There is a thermoelectromotive force or "TC electromotive force" is determined S97, and if not, it is determined whether 7 seconds have elapsed. S98, 7 seconds later, turn off the igniter. S99, S100 as a TC error, and S101 instructing the failure determination means 89. When the thermoelectromotive force is generated within the above 7 seconds, S97, the igniter is turned off and S10
2. It is again determined whether there is a thermoelectromotive force in S103, and if there is a thermoelectromotive force, it is determined whether or not 2 hours have passed in S104, and if two hours have passed, a fire extinguishing instruction is given in S105. When the thermoelectromotive force is exhausted, S103 is performed, and TC error processing is performed at S10.
0.

If it is not the ignition instruction, S79, FIG.
As shown in step S106, it is determined whether the fire is extinguishing operation, and if it is not the fire extinguishing operation, the heating power is changed (described in FIG. 20). In the case of the fire extinguishing operation, first, the target position is set to the closed position, the target encoder position is set to the closed position “100”, and the pulse number is set to the closing movement pulse K.
(The number of pulses from the current position to the closing position is calculated and substituted for K (see the correlation table shown in FIG. 6)) S107. Then, set the speed to high speed and the rotation direction to weak direction, and set the lamp to O
FF is designated and S109, encoder position is "weak to medium weak"
Is determined in step S110, in which case the motor speed is set to a very low speed S111, and otherwise the speed is instructed to be high S112.

Then, through the power saving determination means S113 and the motor speed control means S114 in the drive control unit 58,
A pulse is output via the motor IC in S115, and the number of pulses output to the motor by rotating the motor is counted by a counter "K = K-1" in S116. Whether or not the count number of the pulse counter reaches P before K, which is the target position, is determined by "K <P" S117, and only when the count number is reached is determined by the encoder 35 whether it is the closed position "100" which is the target position, S118, In that case, the number of pulses at the encoder position at that time is replaced with 0 and S119, and S120 is instructed to the drive control unit 58 that the setting of the fire extinguishing position is completed. If the encoder 35 is not the closed position "100" which is the target position, S118, if the pulse counter is not the value "K <-P1" obtained by subtracting P1 from the target pulse number K, S121,
It returns to S110 and repeats S121. If so, S121, S122 going to the motor error SUB (described later).

The reason why the current position is always checked here is to ensure the safety by checking the closed position of the stove that is not used while using the multi stove. Further, the reason why the ignition position is set to the medium high position is to consider sleeve fire measures at the time of ignition for the purpose of medium ignition, and to eliminate anxiety caused by rapid ignition due to strong fire. The 2-hour timer is a hidden timer that prevents you from forgetting to turn it off, and takes into consideration safety and energy saving.

At the time of ignition, the position of the encoder 35 is confirmed by outputting 20 pulses in order to confirm whether or not the slide closure is moving due to insufficient torque at the time of initial operation.
If the slide closure is not movable, it is rotated by a torque-up electric power, which will be described later, and initially has a characteristic of operating with a low torque to reduce the electric power.

Next, the drive determination means 6 for the combustion section when there is an instruction to change the thermal power from the general operating means in the drive control section 68.
The operations of 9, 70 and 71 will be described. The thermal power change shows the case of a five-step thermal power change.

In FIG. 20 and FIG. 21, it is determined whether the thermal power change instruction is UP or not, and if S143 and UP, if the current position is a strong position, it is not accepted, and if it is not a strong position, the target position is set to the current thermal power +1 and S145, The lamp is switched up one lamp and lit up, and the current encoder position is changed to the encoder position E one above based on FIG.
7. Select the motor drive output pulse number P, "pulse number = current pulse (G) + P" S148, and instruct the rotation direction to the strong direction S149. It is determined whether this is the same direction as the previous rotation direction in S150. If it is in the same direction, “target pulse number = pulse number” is set in S151, and if it is not in the same direction, correction (a
S1 in which the value obtained by adding 3) to the pulse number is the target pulse number
52.

When the encoder position is in the weak to medium weak range due to the speed instruction, the speed is instructed to be a slow speed in S153, and when the encoder position is in the medium weak to medium range, it is instructed to be a low speed in S155, and the speed is instructed in the medium to medium strong range. At the time of S157, the medium speed is instructed to S158, and at the time of medium to strong S159, the high speed is instructed to S160. After that, a pulse is output to the motor through the power saving means S161 of the drive control unit 68 and the motor speed control means S161-1, S162, the position determination of the encoder 35 and the number of pulses are counted S163, and an S pulse is output from the target pulse. The "target pulse-S <(G) + (a3) + N" in the foreground is determined in S164, the encoder position E when the condition is satisfied is determined in S165, and the number of pulses is standardized based on FIG. 6 when the condition is satisfied. The position is corrected to S167, the current rotation direction is stored in S168, and the original flow is returned to S169. When the condition is satisfied S164, when the encoder position E is not the designated position S
165, S170 when the pulse number becomes “pulse number + S <(G) + (a3) −N” of S pulse over the target pulse, S170, and goes to motor error SUB S171.

When the instruction to change the heating power is DOWN, S17
2. If the current position is a weak position, it is not accepted S173. If it is not a weak position, the target position is set to the current thermal power position -1 and S1.
74, the lamp is changed from the current one to the position where the heat power is lowered, and S175, 1 from the current encoder position based on FIG.
Change to the encoder position E below by S176, and change the output pulse number of the motor drive to "pulse number = current pulse (G)-
"P" is selected in S177, and the rotation direction is designated as a weak direction S
178. It is determined whether this is the same direction as the previous rotation direction S17
9. In the case of the same direction, set the target pulse number = pulse number and S1
80, if they are not in the same direction, the value obtained by adding the correction value (a3) to the pulse number is set as the target pulse number S181.

When the encoder position E is in the weak to medium weak range due to the speed instruction, the speed is instructed to a very low speed in S182, S183,
When it is in the medium weak to medium range, a low speed is instructed to S184, S185,
When it is in the medium to medium high range, S186 is instructed to medium speed, S187,
When it is medium to strong, S189 is performed to instruct at high speed in S188. After that, a pulse is output to the motor through the power saving means S190 of the drive control section and the motor speed determination means S191, and S
192, the position determination E of the encoder 35 and the number of pulses are counted in S193, and "target pulse + S <(G) + (a3) -N" before the S pulse is determined from the number of target pulses, and S19 is determined.
4. When the condition is satisfied, it is determined whether the encoder position E is the designated position or not S195. When the condition is satisfied, the number of pulses is corrected to the standard position based on FIG. 6, S196, and the current rotation direction is stored S
197, S169 for returning to the original flow. If the encoder position E is not the designated position when the condition is satisfied, S195, the number of pulses is S over the number of target pulses, “target pulse number-S <
(G) + (a3) -N ", S198, and go to motor error SUB S171.

Next, the drive determination units 69, 70, 7 of each combustion unit
"Motor error SU" of the motor malfunction processing in 1
"B" will be described. 22 and 23 show a schematic flow thereof. When a motor error occurs and this routine is entered, the motor speed is increased to S200, the maximum torque is instructed to S201, and the rotation direction is the same as before the error processing. S202, the target position is the same as before the error processing, S203, and the power saving determination means S2 in the drive control unit 68.
S206 of outputting a pulse to the motor through 04 and the motor speed determination means S205. This means that when not operating at normal torque, it is operated again at high torque.

When the rotation direction is strong rotation S207, pulses are counted by the pulse counter and "N = N + 1" S20.
8. The position of the encoder 35 is detected in S209, the encoder 35 determines whether it is the target position in S209, and when the encoder 35 reaches the target position, the number of pulses is hijacked and corrected in FIG.
S211 for returning to the original flow. If the target encoder position cannot be found and N has reached the value obtained by adding the predetermined value M from the previous number of target pulses, it is determined whether "target pulse + M>N" is determined in S212, and if not, the process returns to S203.
When it reaches, it is determined whether it is the first time S213, and when it is the first time, the rotation direction is reversed to the weak direction in S214, the motor speed is increased to S215, the torque is instructed to the maximum, S216, and power saving in the drive control unit 68 is performed. S219 for outputting a pulse to the motor through the judging means S217 and the motor speed judging means S218.

When the number of pulses is counted by the pulse counter 2 and "Q = Q + 1" S220, and Q> 10, S22
1. Reverse the rotation of the motor, set S220 and M = 30, and return to S223 and S203. This means rotating in the opposite direction and eliminating obstacles. The same process is performed according to the flow from S203, and the target encoder position cannot be found in S209, and “target pulse + M (value of M is increased)> N” is determined in S212, and in that case, 1
If it is the second time, S213, and since it is the second time, it is determined that the motor has failed, S224, and the failure processing goes to S225.

When the motor rotation is in the weak direction, S207
The following contents will be changed for the convenience of processing, and that part will be explained. The pulse counter is used to count the pulses, and "N = N + 1" S208 becomes "N = N-1".
226, whether N has reached the value obtained by adding the predetermined value M from the previous number of target pulses, “target pulse + M> N” S212
S227 that satisfies "target pulse-M <N". Otherwise it is the same. These things are considered to operate the motor at normal torque without judging it as a failure at once, and when it still does not have the target position, further back to eliminate obstacles and adjust it to the target position again. By doing so, when a motor error occurs, it is possible to eliminate insufficient torque and the cause of that, such as adhesion of grease at the time of first movement, sticking of the seal part, and unnecessary power consumption to operate with excessive torque in anticipation of these. Moreover, it is possible to eliminate the complaint that it often does not work well.

After that, the frequency is kept constant, and the speed is controlled by intermittently feeding the frequency. The outline method will be described.

In FIG. 24, A is a high speed when a pulse is output at a constant frequency and is 100% speed, B is a middle speed when 1/3 of the frequency is lost, and 67% speed, and C is a speed.
Is a speed of 50% when half the frequency is dropped and 50% speed, and D is a slight speed when two-thirds of the frequency is dropped 3
The speed is controlled at 3%. The advantage of this method is that the torque can be kept constant and there is little fluctuation in speed and designated speed. The outline flow will be described below.

In FIG. 25, the motor speed control means 8
6 determines whether or not there is a drive instruction, S228-1, and whether or not the instruction content from the previous stage is high speed, S228-2. If it is high speed, all pulses of the frequency are output S228-3, and until the stop instruction, S228-1. Repeat to. If not high speed S22
8-2, it is determined whether it is medium speed or not, S228-4, and if it is medium speed, the counter counts the pulses and S228-5, the counter is 3
If not (1 or 2) S229, output a pulse to the motor S231, S22 until a stop instruction is issued.
Repeat to 8-1. Otherwise, when the counter is 3, S2
29, the counter is initialized, S230, and the counting is performed again, S228-5. If it is not medium speed, it is S228-4, if it is low speed, it is judged S230, if it is low speed, the counter counts pulses and it is S233, if the counter is not 2 (when 1) S
234, outputs a pulse to the motor S236, and repeats S228-1 until a stop instruction is given. When the counter is 2, S234 initializes the counter, S235, and causes the counter to count again, S233. If it is not low speed, S232, it is judged to be very fast, S237, in that case, the pulse is counted by the counter in S238, if the counter is 3, S239, the counter is initialized in S240, the pulse is output to the motor in S24.
1. The process is repeated to S228-1 until the stop instruction is given. When the counter is 1 or 2, S239, and S238 for counting again.

With the contents described above, it becomes possible to adjust the speed of the thermal power control suitable for the cooking utensil.

The above-mentioned change of heating power is also applied to the automatic cooking mode of the stove, and the relationship between the automatic cooking mode and the adjustment of heating power will be described below with reference to FIGS. 26 to 28.

The automatic discrimination cooking mode in the left stove drive determination unit 69 without mode selection will be described. In the case of the left stove, the cooking mode determination unit 9 of the left stove drive determination unit 69.
3 executes the processing procedure of the flowcharts shown in FIGS.

In FIG. 26, the temperature determination unit 92 takes out the temperature detected by the pan bottom temperature sensor 2 in S242, performs an arithmetic processing on this temperature data in S243, and inputs the calculation result to the cooking mode determination unit 93. The cooking mode determination unit 93
From the calculation result, it is determined whether or not water cooking is performed, S244,
In the case of water cooking, after determining the non-sticking temperature from the boiling temperature S245, the process is transferred to the non-sticking determination unit 94 S246.

When it is determined in the previous step S244 that the cooking is not for cooking with water, it is determined to be cooking with oil.
247, and thereafter, in order to monitor the overheating of the oil cooking, after the overheating prevention temperature of the oil cooking is determined S248, the processing shifts to the overheating prevention determination unit 95 S249.

Next, the processing operation of each part to which the processing is transferred from the cooking mode determination part 93 will be described.

The anti-focus determination section 9 to which the processing has been shifted from step S246 of the processing procedure of the cooking mode determination section 93.
The processing procedure of No. 4 is shown in FIG. Regarding the sensor temperature which is the temperature detected by the pan bottom temperature sensor 2, the condition judgment of “sensor temperature> non-sticking temperature −15 ° C.” is performed and S2 is performed.
50, S2 in which it is determined whether this condition is met for the first time
51. If this is the first time, a buzzer will inform you, and if it is not the first time, it will be in a state of burning,
Since it is considered that it still takes some time, a command signal for setting the left stove gas control unit 29 to the weak position is output to the left stove drive determination unit 69 (S253). The left stove drive determination unit 69 controls the flow heating control mechanism 33 by the motor 34 so that the gas flow rate is at a weak position and weakens the combustion thermal power.

Next, the burning timer is turned on and S
254, it is determined whether or not X seconds have elapsed, and S25
After the lapse of 5, X seconds, the condition determination of “sensor temperature> non-sticking temperature” is performed in S256, and when the condition is satisfied, it can be determined that there is burning, so the left stove drive determination unit 6
The left stove gas control unit 29 is closed by the control of 9 (OF
F) S257.

If the condition of "sensor temperature> non-sticking temperature" is lower than the non-sticking temperature by the determination processing of step S256, "sensor temperature>
The condition determination of “non-sticking temperature −5 ° C.” is performed in S258,
When the condition is satisfied, a command for setting the gas control unit 33 to the medium heating power position is output to the left stove drive determination unit 69 and S25 is output.
9. If the condition determination in step S258 is not established, the process returns to step S250.

By the processing operation of the anti-sticking determination section 84, the processing for preventing the burning in the water cooking (boiled food) is performed based on the detection of the pan bottom temperature by the pan bottom temperature sensor 2, and the user is separated from the gas cooker. When
The process of stopping the combustion of the left stove 1 is executed before the burning occurs.

FIG. 28 shows the processing procedure of No. 5.

"Sensor temperature> Overheat prevention temperature-10 ° C"
The condition is determined in step S260. When this condition determination is established, it is determined whether or not this is the first time, and the determination is S261,
If it is the first time, a buzzer or the like is used for notification S262, and the left stove drive determination unit 69 outputs a command for drive control to the weak position to the gas control unit 29 S263. Previous step S261
If it is not the first time in the determination of, the process proceeds to step S263 without notifying the buzzer. Next, the condition judgment of "sensor temperature> overheat prevention temperature" is made and S26
4. When the condition is satisfied, it is in an overheated state, so a command is issued to the left stove drive determination unit 69 to cause the gas flow rate control unit 33 to close, and the processing ends (S265).

When the condition determination in step S264 is not established, the condition determination of "sensor temperature <overheat prevention temperature-18 ° C" is performed in S266, and when the condition is established, the left stove drive determination unit 69 is controlled by gas control. Part 2
A command to control 9 to the strong fire power position is output, and the process returns to S267 and S260. When the condition is not satisfied, the condition judgment of “sensor temperature <overheat prevention temperature−5 ° C.” is made in S268, and the gas control unit 2 is set in the left stove drive judging unit 69.
A command for controlling 9 to the medium thermal power position is output, and the process is returned to S269 and S260.

As described above, it is possible to prevent the risk of fire by preventing abnormal heating of the tempura oil when the tempura is fried and leaves the place.

Next, automatic cooking of the grill will be described.
FIG. 29 illustrates the concept of automatic grill cooking, in which the vertical axis represents the temperature of the temperature sensor inside the grill and the thermal power used, and the horizontal axis represents the time after ignition.

The temperature which was room temperature at the time of ignition rises with time and reaches the firing measurement start temperature at point a. After that, when the bake-up measurement ending point at point b is reached, the gradient ba-a /
Calculate t. The burning of the fish is determined by this gradient, and the subsequent heating power and time are set. Although this figure shows the state where the room temperature starts, the inside temperature is not determined to start at room temperature. In the case of a large family, there are cases where automatic fire extinguishing is performed and fish is subsequently grilled, so it is necessary to measure the gradient other than when room temperature starts and to control the thermal power according to the start temperature.

When the temperature rises after the gradient is determined and point c is reached, the first thermal power change point, the thermal power at the initial stage of ignition, for example, 2200
When the heating power is switched from kcal / h to 1700 kcal / h and the fish is heated to reach point d, that is, the second heating power change point, the heating power is further switched to 1400 kcal / h. When a predetermined time has elapsed, the fire is automatically extinguished to complete the fish grilling.

The big difference from the manual cooking is that in the case of manual cooking, the heating power is constant from the time of ignition to the end of the fish grilling without changing the heating power. In the case of automatic cooking, the heating power is changed according to the temperature rise. It is to switch. This difference can be evaluated by the degree of tolerance of the time in the baked state. In the case of manual operation, 3 horse mackerels are baked in 12 minutes, ± 1
An error of about a minute is allowed for a degree of charring. 1 for automatic
The error of about ± 2 minutes after baking in 4 minutes is the same as the manual error.

Compared to manual operation, the automatic operation is performed with a slightly weaker heating power, and even if the time is lengthened a little, the error due to the burn-up determination is absorbed and the baking amount is carefully considered.

FIG. 30 is an enlarged view of the grill operating portion.
Depending on the type of fish and the degree of processing, the number of fish that can be processed with the same key is limited. Therefore, a fish species selection key is provided, and those with similar correlation between temperature rise and firepower are accumulated, and raw / figure key, fillet key, dried fish key are provided as a key selection configuration, and the degree of charring is further selected. The setting of firepower and time was taken into consideration with the reference fish shown in the table as the three-level selection of the brown key.

[0112]

[Table 1]

As shown in the above table, it is necessary to make the set heat power different depending on the food to be cooked, and it is not necessary to bake it at a constant heat power for a fixed time. The degree of browning is also the degree of burning as shown in the table above, but it can also be matched by the characteristics of the fish. With this in mind, the control, temperature and combustion time are set.

The ignition fire power does not guarantee that the same fire power can obtain the same degree of baking in the raw form and the dried fish. They are fish and raw fish, and fish and dried fish. If you try to bake with the same firepower, it will be very difficult to manage the time. Of course, it is possible to reduce the heating power and steam it slowly like an oven, but without the characteristic of the deliciousness of the grill, the user's satisfaction cannot be obtained.

The above is the basic concept of grill automation.

The following is a description based on the flow of the automatic grill. FIG. 31 shows a main routine flow of the automatic grill of the present invention. First, if there is a manual overheat prevention flow and there is a fish species mode, S270, if not, set the first heat power switching temperature to 150 ° C to operate for manual overheat prevention, set S271, set automatic fire extinguishing time 15 minutes, and automatically extinguish The temperature is set to 190 ° C., S272, it is determined whether the sensor temperature is 150 ° C. or higher, S273, and if it is, switch to the first thermal power “medium” S273-1, 15 minutes have passed thereafter, or the sensor temperature is 190 ° C. or higher. It is determined whether the temperature has risen in S274, and if either of them is satisfied, the fire is automatically extinguished S
275. The above is the operation of the manual overheat prevention.

The purpose in this case is to guarantee the minimum condition that the fish should not burn.

Therefore, the fish are too burnt to eat, as a matter of course.

On the other hand, if there is a fish species mode, S270 shifts to automatic heating prevention, that is, automatic grill flow. That is, it is determined whether or not the fish species mode is raw / figure S276, and if so, the fish species mode 1 is stored and S276-1, otherwise, it is determined whether or not the fish species mode is fillet S277, and if yes, the fish The species mode 2 is stored in S277-1, otherwise the fish species mode is determined to be dried fish S278, and if so, the fish species mode 3 is stored in S278-1. In this case, the three fish species modes are cyclic,
Migrate with the last choice.

After determining the fish species mode, it is then determined whether the charring key is "strong" in S279, and if so, the charring mode 1 is stored in S279-1. If not, it is determined whether the charring key is "medium". S280, in that case, the burn mode 2 is stored and S280-1, otherwise, it is determined whether the burn key is "weak" S281, and the burn mode 3 is stored in S281-1. In this case, the three dark-keys are cyclic, and the one selected last is used for the transition. When the burning mode is determined, the procedure goes to gosub firing determination heating power S282 and returns (the gosub firing determination heating power will be described later).

[0121] Gosub burning determination thermal power S282 is switched to the designated thermal power set in S282 for combustion, and the temperature of the sensor temperature for measuring the inside temperature of the grill is periodically fetched S284. The initial temperature is stored as the initial temperature (TS
O = initial temperature) S285. It is determined whether the initial temperature is lower than 50 ° C. S286, and if so, the start mode 1 is stored in S2.
86-1. If not, it is determined whether the initial temperature is lower than 100 ° C. S287, and if so, the start temperature mode 2 is stored S287-1. If not, the initial temperature is set to 100 ° C. or higher and the S288 starting temperature mode 3 is stored.
1. After that, the process goes back to the gosub burning determination heating power S289 again, and returns to the designated burning power set in the gosub burning determination heating power S289 to burn (S289-1). Then g
go to erase forget timer time S289-2 and return (the go erase forget timer time will be described later). After that, the forget-to-remove timer (KJ) is turned on, S289-3, and the automatic fire extinguishing timer counter (JS) is turned on (JS = JS +
1) S289-4, go to gosub baking determination and return S
289-5 (Gosub burning determination will be described later).

In FIG. 32, the first thermal power designated by the gosub burning determination is stored in S290, the first thermal power switching temperature K1T is stored in S291, and the combustion upper limit time ULT of the first thermal power is stored in S292. Lower limit combustion time LLT is memorized and S
293, the switching temperature K2T of the second thermal power is stored in S29.
4. S295 storing the second heat power, S296 storing the automatic fire extinguishing time JST. After that, the temperature K1T at which the stored burning determination thermal power is switched to the first thermal power is set and S29 is set.
7. K1T <TH is judged whether it is the first heat power switching temperature or not, and S2 is set.
98, if the switching temperature is reached, switch to the first thermal power S299,
S300 for setting combustion limit times ULT, LLT.

Combustion is performed with the first thermal power, the second thermal power and the switching temperature K2T are set in S301, and it is determined whether the switching temperature from the first thermal power to the second thermal power is K2T <TH in S302. It is determined whether LLT is less than or equal to the lower limit value <JT, S303, and in that case, the process proceeds to the next step. If not, the process waits until the JT timer is equal to or greater than the LLT and proceeds to the next step. If the temperature is below the determination temperature, S302, the first
More than the upper limit temperature to change from thermal power to second thermal power ULT <JT
Whether or not it is determined in S304, and if so, the process proceeds to the next step. Waiting for either of them to become the designated content, and switching to the second thermal power S305.

After switching to the second heating power, it is judged whether or not the grill combustion automatic fire extinguishing time has come (JT = JST) S306, and if not, the forget-for-cut prevention time has come (KJ <JST> judgment S306-1). If this is also not the case, CB <TH determination is made as to whether the automatic fire extinguishing temperature has been reached, S306-2, and if it has reached S306, S306-1,
At the same time, the fire is automatically extinguished and the buzzer is notified to end the step S307. The steps S306-1 and S306-2 are a flow showing the automatic overheat prevention determination unit, and the optimum value is set by the most preferable experimental result represented by the matrix in the selection of the fish species and the charred eyes.

FIG. 33 is a flow chart showing a subroutine for burn-up determination thermal power. It is a two-digit number because there is no temperature data among the fish species mode, browning, and starting temperature at the first time. The second time is a three-digit number because there is temperature data.
Therefore, it is determined whether there are two digits, S308, and in the case of two digits, 1 is added to the lower digit, S309. Similar to the case of 3 digits, the corresponding heating power is selected from the matrix S310, and returned to the original S311. For example, in the case of 1, 2, 1 the firepower used is "strong", in which case the first 1 is the fish mode "raw.
The figure shows that the charring mode is standard and the starting temperature mode is room temperature starting. In the case of the states 1, 2, and 3 at the time of the second time, the third digit 3 indicates the start of high temperature, and the used thermal power is "medium". The above is the fish species mode, brown eyes,
The content of changing the thermal power at the starting temperature is shown.

In the above-mentioned state, the burn-up determination thermal power is automatically selected from the designated thermal power according to the set fish species and the starting internal temperature. This means trying to create the most preferable grilled state with the heat power that matches the fish species from the time when the fish is put in the refrigerator depending on the fish species, and changing the heat power also depending on the starting temperature, at high temperatures at low temperatures. This is to solve the problem that the surface of the fish is scorched and the fire does not reach inside.

FIG. 34A shows the flow of the forget-to-delete timer subroutine. Select from the matrix S
312, the erase-forgetting prevention time BT is substituted and S313, and it returns. The fish species mode number, the charring mode number, and the three-digit number depending on the starting temperature mode number, for example, 2, 2, 1 are the fish type mode "fillet", the charring mode is standard, the starting temperature mode is "room temperature". There is, and the forget-to-delete timer in that case is from the matrix, and the timer time is 15 minutes.
These 15 minutes are passed as an argument.

Originally, the purpose of the timer for forgetting to turn off is to prevent grill fire. In that sense, the manual forget-to-remove timer has one time as a safety timer so that a fire will not occur in the worst combination, because the fish species to be used is not clear. Of course, fish are too burnt to eat.

On the other hand, since the automatic cooking timer selects and inputs the fish species with the fish species key, the main purpose is to set the fish so that it can be eaten although it is slightly burnt. To this end, the purpose of this routine is to define a fish species key and a standard fish for each individual key for each brown key, and to create a state in which the maximum time is individually set and managed. Therefore, although the time may be longer than the manual timer, the species of fish is clear, and accordingly, the fire power is weakly changed after the fire power from the ignition to the end of burning, and the ignition is suppressed. .

Also, since the heating power is suppressed, for example, the timer 17 minutes in the state of the strong key of raw / figure which requires the most heating power, by mistake, does not require the large heating power in this state. It is also possible to set the time so that it will not catch fire even if you put in "weak" fish. Also, ignoring the above, if you burn a weak fish of dried fish, it will ignite,
It is also possible to set the time by giving priority to the raw and strong workmanship. The meaning of the above is changed depending on the time taken in the matrix here.

Further, regarding the automatic fire extinguishing time of the matrix, it is possible to create and calculate a relational expression between the starting temperature and the automatic fire extinguishing time, and this case is also an example of the same idea.

FIG. 34 (b) shows the temperature that regulates the upper limit temperature of overheating of the automatic overheat prevention flow. A matrix is created according to the fish species, the charring mode, and the starting temperature, and the most preferable temperature under each condition ( From the experimental results, it was decided that the temperature at which the fish could be eaten even if the fish was a little scorched, if possible, did not cause the fire of the fish, the premature cutting of the fish to be cooked, and the like. Regarding the automatic extinguishing temperature of the matrix, it is possible to create and calculate a relational expression between the starting temperature and the automatic extinguishing time, and this case is also an example of the same idea.

FIG. 35 is a flow chart showing a burn-up determination subroutine. Bake judgment is made in 3 fish species modes and 3 start temperatures
It depends on the type, and is composed of 9 types of burn-up determination patterns. For example, in the case of the fish species mode “raw / figure” and the start temperature mode “low temperature”, the mode numbers are 1 and 1, and the matrix becomes “A pattern”. A pattern is selected from the matrix in S316, it is determined whether the selected pattern is A or not, S317, and if not, the process proceeds to FIG. 36. If it is, it is determined whether the sensor temperature reaches 50 ° C., S318,
When the temperature reaches 50 ° C., the time (T50) when the temperature reaches 50 ° C. is stored and stored in S319. Then, it is determined whether or not the sensor temperature reaches 100 ° C., S320, and when the temperature reaches 100 ° C., the time (T100) when 100 ° C. is stored. S321. Next, S322 for calculating the gradient calculation (TK = T100-T50).

Thereafter, the first thermal power switching temperature K1T = 110.
℃ is specified S323, 1st thermal power = "Medium" is specified S32
4, set the "first thermal power switching upper limit time ULT = 20" for switching from the first thermal power to the second thermal power, S325, switch to the second thermal power from the first thermal power, "the first thermal power switching lower limit time LLT
= 326 "is set in S326. Next, it is determined whether the burn mode is 1, S327, and in that case, the combustion time calculation JST = A1 × T
S328 to perform K + α1. If not, then it is determined whether the burning mode is 2, S329, and in that case, the combustion time calculation JST = A2 × TK + α2 is performed S330. If not, the burning mode is 3 and S331, and the combustion time calculation JST = A3 × TK + α3 is performed S332. After completion of the calculation in any of the burn modes 1, 2, and 3, the first heat power switching temperature K2T = 140 ° C. is designated in S333, the second heat power “weak” is designated in S334, and the process is returned to S335.

Here, JST = A1 × TK + α1 in the calculation of the combustion time from the start of combustion, where A1 and α1 are the standards of this mode (when the room temperature of raw / appearance starts and the degree of charring is strong). Is the coefficient that bake the fish most properly,
This coefficient also needs to be changed depending on the selection of the charcoal.
In addition, this coefficient must be determined for each fish species mode.

This flow shows the most common "raw / figure" fish roasting flow starting at room temperature, and is used when roasting horse mackerel and swordfish. The degree of browning is adjusted depending on the length of time, and the burning judgment is determined by the temperature rise degree from 50 ° C to 100 ° C, and the burning judgment is performed by the temperature rise degree, and the burning time is determined from the result of the burning judgment. is doing.

What is different from the conventional method is that the heat power is changed in accordance with the degree of progress of grilling the fish. In one step, the temperature inside the grill is raised by the "strong" heat power to grill the surface of the fish and judge whether the fish is grilled or not. To do.

Effect "The deliciousness of fish is that at first, at high temperature, the oil between the scented skin and the body is burnt out at high temperature to confine the umami inside, and this is achieved."

Two-stage, "medium" that can heat both inside and outside the fish
Uses thermal power to quickly raise the internal temperature without burning too much.

Effect "Prevents the fish from draining and becoming dry when heated for a long time with an appropriate heating power that heats the inside quickly and without burning too much on the surface".

In three steps, the outside is not burnt, and the heat is "weak" that allows heat to penetrate into the inside and eliminate the state of raw burning.

Effect "The reliability of the automatic grill is not too charred,
It is a guarantee that it is not a raw burn, and realizes the penetration of heat into the interior with low heat. "

Therefore, for this purpose, a backup software structure is provided for ensuring the two-stage effect by adjusting at which temperature the heat power is switched, and by providing the upper and lower limit time limit timers for the two-stage heat power.

In order to improve the accuracy, it is preferable to measure the gradient of the raw figure fish from a temperature as low as possible to around 100 ° C. for a long time. This is because there is a skin, and the water content inside is gradually released without being released for a period of time. On the other hand, the characteristics of fillets and dried fish show their characteristics in a short time compared to their appearance, and there are many errors when measuring for a long time. Also, in the case of fillet, compared to the appearance, the thickness of the body is half and the water content comes out faster. In the case of dried fish as well, the gradient appears only at the beginning, but there is a drawback that the temperature change due to moisture is small and the error becomes large over time. Therefore, depending on the fish species, the most preferable burning determination temperature zone is not the same from the above characteristics, but is determined individually. The present invention has a point here.

In the case of raw / appearance, the gradient is measured from a low temperature, but when the temperature inside the cabinet is warm, the gradient is curved due to the temperature rise in the cabinet at the beginning of ignition, and the characteristic of the fish appears. There is no temperature range, and that temperature range is 25
K degree cannot be used. Therefore, if the temperature is not corrected, the temperature will be 25 ° C. or lower when the gradient measurement is performed from 50 ° C.

Of course, when the starting temperature is 50 ° C., it is impossible to use the room temperature sequence (gradient measuring method of 50 to 100 ° C.), and the pattern B is provided to solve this problem.

FIG. 36 is a flow chart showing pattern B (raw / appearance, starting temperature / intermediate temperature). It is judged whether it is the B pattern or not S33
6. If not, go to FIG. 37. If so, did the current sensor temperature rise + 10 ° C. above the starting temperature (TS
(O + 10 ° C.) <TH is determined in S337, and after that, the time T10 = JS increased by 10 ° C. from the time of ignition is stored in S338. Next, it is determined whether the burn mode is 1, S3
39, and if so, calculate the burning time (JST
= B1 × T10 + β1) S340 Go to the next step. If not, it is determined whether the burning mode is 2, S341, and if so, the combustion time is calculated (JST = B2 × T10 + β
2) S342 Go to the next. If not, the burn mode is determined to be 3 and S343 is calculated, and the burning time is calculated (JST =
B3 × T10 + β3) S344, only in the case of the burning mode 3, the first thermal power switching temperature K1T = 110 ° C. and S345,
The first thermal power is instructed to “medium”, S346, the first thermal combustion upper limit time ULT = 20 is set to S347, the first thermal combustion lower limit time LLT = 3 is set to S348, and then the starting temperature is 8
Whether the temperature is 0 ° C. or lower or TSO <80 ° C. is determined in S349, and in that case, the second thermal power switching temperature K2T = 140 ° C. is set in S350, and the process proceeds to the next step.

On the other hand, when the temperature is 80 ° C. or higher, the second thermal power switching temperature is calculated according to the start temperature by a linear equation in which the temperature is 140 ° C. at 80 ° C. and 150 ° C. at 100 ° C. (K2T = Q1 ×).
TSO + P1) S351, and proceed to the next.

After calculating the burning time in the burning modes 1 and 2, the first thermal power switching temperature K1T = 120 ° C. is set and S35 is performed.
2. Set the first thermal power to "medium" S353, set the first thermal combustion upper limit time ULT = 20 to S354, set the first thermal combustion lower limit time LLT = 3 to S355, and if the starting temperature is 80 ° C or lower TSO <80 ° C. is determined S356, and in that case, the second thermal power switching temperature K2T = 150 ° C. and S35
7. Go to the next step. On the other hand, when the temperature is 80 ° C. or higher, the second thermal power switching temperature is calculated according to the start temperature by a linear equation that sets 150 ° C. at 80 ° C. and 160 ° C. at 100 ° C. (K2T = Q2 ×
TSO + P2) S258, and proceed to the next. In any case, the second heating power is set to "weak" in S359, and returned to S3.
60.

Here, JST = B1 × TK + β1 in the calculation of the combustion time from the start of combustion, where B1 and β1 are the standards of this mode (when the medium temperature of raw / appearance starts and the degree of charring is weak). Is the coefficient that bake the fish most properly,
This coefficient also needs to be changed depending on the selection of the charcoal.
In addition, this coefficient must be determined for each fish species mode.

In the B pattern, the gradient measuring method is different from the room temperature starting method, and the gradient is measured by the 10 ° C. rising method. This method is less accurate than the time measuring method from 50 ° C. to 100 ° C., but the starting temperature is high, so it is the second method for measuring the gradient. In addition, the switching temperature to the 1st thermal power is also classified according to the starting temperature, but consideration is given to creating the optimal state by the balance of the time of putting in the high temperature chamber with the thermal power "strong" and the baking of the sensor temperature. It is an invention that made. In addition, when starting above 80 ° C, the switching temperature to the 1st thermal power is calculated by the linear equation depending on the starting temperature.
When the temperature becomes high, the balance of baking changes slightly depending on the degree of elongation during a strong time (when the temperature becomes high, the temperature rise becomes slower,
This is because the degree of influence is large correspondingly, and thus fine control is required). The heat switching temperature is changed according to the degree of selection of charcoal, but when charcoal is "weak", it has a small capacity such as small horse mackerel, and the heat penetrates relatively quickly to the inside. By switching to firepower earlier, the automatic fire extinguishing time is also shortened, which has the dual effect.

FIG. 37 shows the flow of the C pattern (raw / appearance, starting temperature 100 ° C. or higher). Determine if it is a C pattern, S
361, otherwise go to FIG. 38, and if that is the case, the current sensor temperature is + 10 ° C. higher than the start temperature (TSO + 10 ° C.) <TH is determined S 362, and after that, wait from that time for ignition. Time T10 when 10 ℃ rises
= S363 for storing JS. Then, it is determined whether the burn mode is 1, S364, and if so, the combustion time is calculated (JST = C1 × T10 + γ1) S365, and the process goes to the next step.
If not, it is determined whether the burning mode is 2 or not, S366, and if so, the combustion time is calculated (JST = C2 ×
T10 + γ2) S367 Next. If not, the burn mode is determined to be 3 and S368 is calculated, and the burning time is calculated (JST = C3 × T10 + γ3) S369. In either burn mode, the start temperature is lower than 140 ° C. or TSO <14.
0 ℃ judgment S370, in that case the second thermal power switching temperature K2
Set T = 150 ° C., S371, and proceed to the next. On the other hand, when the temperature is 140 ° C. or higher, the second thermal power switching temperature is calculated by a linear equation that sets 150 ° C. at 140 ° C. and 170 ° C. at 160 ° C. according to the start temperature (K2T = Q2 × TSO + P2) S372,
After that, the combustion switching upper limit time ULT = 7 minutes to the second thermal power is set to S373, the combustion switching lower limit time LLT to the second thermal power is set to LLT = 4 minutes, S374, and the second thermal power is designated as "weak" S375, combustion. When the time is less than the minimum combustion time (JST <CT2) S376, the minimum time is replaced with a predetermined time (JST = CT2) S377 and then FIG.
* S378 going to A.

Here, JST = C1 × TK + γ1 in the calculation of the combustion time from the start of combustion, where C1 and γ1 are the standards of this mode (when the temperature of raw / appearance starts high and the degree of charring is strong). Is the coefficient that bake the fish most properly,
This coefficient also needs to be changed depending on the selection of the charcoal.
In addition, this coefficient must be determined for each fish species mode.

This flow is a flow to be used when the next fish is immediately grilled after the automatic fire extinguishing after starting high temperature and finishing the grilling. The temperature inside the refrigerator is 160 ° C 1 minute after the automatic fire extinguishing and about 140 ° C at the time when 2 minutes have passed. Yes, when the object to be burned is placed in such a high temperature, the thermal power switching temperature has poor followability in stepwise control, and linear temperature switching is required. In addition, when baking judgment is performed with a temperature gradient from the rising temperature, the accuracy may not be so accurate, so as a method to be used in combination with the time limiter, prevent overburning and raw burning I am devising.

FIG. 38 shows D pattern (fillet, room temperature start).
Shows the flow of. It is determined whether the pattern is the D pattern, S379,
If not, go to FIG. 39. If so, determine whether the sensor temperature has reached 50 ° C., S380, and when it reaches 50 ° C., store the time (T50) at which it reached 50 ° C., S38.
1. Next, it is determined whether the sensor temperature has reached 80 ° C. S38
2. Time when it reaches 80 ° C when it reaches 80 ° C (T80)
Is stored in S383. Next, the gradient calculation (TK = T80-T
S384 to calculate 50). Next, it is determined whether or not the burn mode 1 is S385, and if so, the combustion time calculation (JST = D
1 × TK + δ1) is performed S386, the second thermal power switching temperature K
2T = 200 is instructed, S387, second heat power = “medium” is instructed, S388, and the process goes to the next step.

On the other hand, if the burning mode is not 1, S385,
Whether or not the burn mode is 2 is determined in S389, and in that case,
Burning time calculation (JST = D2 × TK + δ2) is performed and S3
90, the second thermal power switching temperature K2T = 90 is instructed and S39
1, go next. On the other hand, if the burn mode is not 2, S38

ST = D3 × TK + δ3) is performed in S393, the second thermal power switching temperature K2T = 80 is instructed, and S394, the second thermal power =
"Weak" is instructed S395, burnt modes 1 and 2 are combined, and UTL = 20 is instructed S396, LLT = 7 is instructed S397. Is the combustion time calculation value smaller than the D mode minimum combustion time DT2? JST <DT2 judgment is made S398,
In that case, replace with JST = DT2 S399, DT2
In addition to the case where it is larger, go to * A in FIG. 32 S400.

Here, JST = D1 × TK + δ1 in the calculation of the burning time from the start of burning, and D1 and δ1 are the reference fish of this mode when in this mode (when the fillet starts at room temperature and the degree of charring is strong). The most appropriate baking coefficient,
This coefficient also needs to be changed depending on the selection of the charcoal.
In addition, this coefficient must be determined for each fish species mode.

The above is the operation flow of the fillets starting at room temperature. Compared with the appearance, if the charcoal is strongly charred, it is burned through medium heat. This is based on the experimental results that it proves that the fillet can be baked deliciously by lowering the heating power by one step as compared with the appearance, and is a preferable baking method even if it is manual.

The discrimination temperature is 50 to 80 ° C., which is measured at a lower temperature than the raw / appearance 110 ° C.
As described above, the determination is made by catching the points where the characteristics of the fish are most apparent.

In the burn mode 2 (medium) and 3 (weak), the temperature is lower than that of the figure (in the case of the fillet, the heat power is switched from medium to weak at 90 ° C, and in case 3 the heat power is switched from medium to weak at 80 ° C. )
(In the case of the figure, the thermal power is switched from strong to medium at 110 ° C), but in this way, both the thermal power used and the switching temperature are changed depending on the fish species and the starting temperature, and consideration is given to properly grill the fish, The firepower most suitable for the characteristics of the fish is set, and an automatic fire extinguishing timer is assembled by standing on it. In short, how to properly perform preparations (appropriate firepower management, proper firepower changeover temperature, proper fish species key setting, proper setting of brown eyes) capable of timer management is the main purpose of the present invention.

FIG. 39 shows E pattern (fillet / start of medium temperature).
Shows the flow of. It is determined whether the pattern is an E pattern, S401,
If not so, go to FIG. 40. If so, 110 <TH judgment is made as to whether the sensor temperature has reached a predetermined temperature or not, S40.
2. Waiting for the temperature to reach the predetermined temperature is stored (T110 = JS) S403. Then calculate the time per unit temperature JK = T110 / (110 ° C-
TSO) S404: TSO is the starting temperature. Next, it is determined whether the burning mode is 1, S405, and in that case, the burning time calculation JST
= E1 × JK + ε1 is performed in S406, the temperature for switching to the second thermal power K2T = 140 ° C. is set, and the process proceeds to S407. On the other hand, if the burn mode is not 1, it is determined whether the burn mode is 2 or not.
8, in that case burning time calculation JST = E2 × JK + ε2
Perform S409. If the burning mode is not 2, the burning mode is set to 3 and S410, burning time calculation JST = E3 × JK
S411 of performing + ε3.

In both the burning modes 2 and 3, the switching temperature K2T = 110 ° C. to the second heating power is set to S412, and in the burning mode 1, the heating power of the second heating power is weakly designated to S41.
3, ULT = 20 (S414), LLT = 3 (S41

6. In that case, switch to JST = ET2 S417, and go to * A in FIG. 32 S418.

[0163] Although the burning determination method is time per unit temperature, this is different from the case of fillets in that it evaporates water relatively quickly, so it can be treated as time per unit temperature. This is because it improves accuracy.

Here, JST = E × TK + ε1 in the calculation of the combustion time from the start of combustion, and E1 and ε1 are the reference fish of this mode when in this mode (when the fillet is at a middle temperature and the degree of charring is strong). The most appropriate baking coefficient,
This coefficient also needs to be changed depending on the selection of the charcoal.
In addition, this coefficient must be determined for each fish species mode. Compared to room temperature start, the middle temperature start of the fillet is set in relation to the start temperature, the heating power switching temperature is set high, the heating time suitable for the fillet is adjusted by adjusting the heating time of the medium heat power, and the management of the workmanship is done. I am doing it.

FIG. 40 shows F pattern (fillet / high temperature start)
Shows the flow of. It is determined whether the pattern is the F pattern S419
If not, go to FIG. 41. If so, is the sensor temperature 10 ° C. above the start temperature (TSO + 10 ° C.) <T?
Judged H, S420, waited for that to happen, and started from 10
Memorize the time when the temperature reaches ℃ (T10 = JS) S42
1. Then, it is determined whether the burn mode 1 is S422, and at that time, the combustion time is calculated (JST = F1 × T10 + ζ1).
S423, the switching temperature to the second thermal power K2T = 140 ° C. is set and S424, and the process proceeds. If not, it is determined whether or not the burn mode 2 is S425, and at that time, the combustion time is calculated (J
ST = F2 × T10 + ζ2) S426. If not, the burning mode is set to S427, the burning time is calculated (JST = F2 × T10 + ζ2) S428, and the process proceeds to the next step.

When the combustion calculation of the burning modes 2 and 3 is completed, the switching temperature K2T = TSO + 10 ° C. for the second heating power is instructed S429, and the second heating power = weak instruction is given together with the result of the burning mode 1 in S430. , ULT = 20 (S431), L
LT = 3 (S432) is instructed, and the combustion time calculation value is F.
Is it less than the minimum combustion time FT2 of the mode or JST <FT
2 determination is made in S433, in which case JST = FT2 is replaced with S434, and S435 goes to * A in FIG. 32.

Here, in the calculation of the combustion time from the start of combustion, JST = F × TK + ζ1, and F1 and ζ1 are the reference fish of this mode when in this mode (start of high temperature of fillet and strong degree of charring). The most appropriate baking coefficient,
This coefficient also needs to be changed depending on the selection of the charcoal.
In addition, this coefficient must be determined for each fish species mode.

FIG. 41 shows the flow of the G pattern (dried fish, starting at room temperature). If it is the G pattern, S436 is determined. If not, the process proceeds to FIG. 42. If it is, it is determined whether the sensor temperature reaches 50 ° C., and S437, when it reaches 50 ° C., the time at which the temperature reaches 50 ° C. (T50). Remember S4
38, then it is determined whether the sensor temperature has reached 80 ° C., S4
When the temperature reaches 39 and 80 ° C, the time when it reaches 80 ° C (T8
S440 of storing 0). Next, the gradient calculation (TK = T80
S441 to calculate -T50). Next, it is determined whether or not the burn mode 1 is S442, and if so, the combustion time calculation (JST
= G1 × TK + η1) is performed in S443, and the process proceeds to the next step. On the other hand, if the burning mode is not 1, it is determined in S442, and if the burning mode is not 2, it is determined in S444 that the combustion time is calculated (JS
T = G2 × TK + η2) is performed and the process proceeds to S445. Further, if the burning mode is not 2, S444, if the burning mode is 3, S446, burn time calculation (JST = G3 × T
K + η3) is performed at S447, and then burnt mode 1, 2,
In any case of 3, the second thermal power switching temperature K2T = 120
To indicate S448, and the second heat power = “weak” is indicated to S44.
9, UTL = 20 is instructed, S450, LLT = 3 is instructed, S451, JST <GT2 is determined whether the value of the combustion time calculation is smaller than the minimum combustion time GT2 of the G pattern, S45.
2. In that case, replace JST = GT2 with S453, and go to * A in FIG. 32 S454.

Here, in the calculation of the combustion time from the start of combustion, JST = F × TK + η1, and when F1 and η1 are in this mode (when the fillet starts to be hot and the degree of charring is strong), the reference fish of this mode is used. The most appropriate baking coefficient,
This coefficient also needs to be changed depending on the selection of the charcoal.
Also, when compared to fillet, switching the heat power from "medium" to "weak" is the same, but the switching temperature is 9 for fillet.
0 ℃ and 120 ℃ for dried fish. Dried food tends to become crispy unless it is in a high temperature atmosphere and cannot be exposed at low temperature for a long time. In terms of time, the temperature rise of fillets is slower than that of dried fish, and the duration of exposure to "medium" thermal power is determined in consideration of the fact that fillets are longer. Therefore, instead of simply estimating the baking time from the gradient, the time is set based on a comprehensive judgment as to what temperature the heating power should be heated to and how many times the baking time is appropriate. As a result, if the heating power switching temperature changes, it is naturally possible to provide a stable automatic grill by changing the baking time and determining the amount of baking.

FIG. 42 shows the flow of the H pattern (dried fish / medium temperature start). If it is the H pattern, it is determined in S455. If not, the process proceeds to FIG. 43. If it is, the sensor temperature is 10 ° C. higher than the start temperature (TSO + 10 ° C.) <TH

7. Then, it is determined whether the burn mode 1 is S458, and at that time, the combustion time is calculated (JST = H1 × T10 + θ1).
S459, the temperature for switching to the second thermal power K2T = 140 ° C. is set, and the process proceeds to S460. If not, it is determined whether or not the burn mode 2 is S461, and at that time, the combustion time is calculated (JS
T = F2 × T10 + θ2) S462. If not,
Burning mode 3 is set to S463, and burning time is calculated (JS
T = F3 × T10 + θ3) S464, the process proceeds to the next.

When the combustion calculation of the burning modes 2 and 3 is completed, the switching temperature K2T = 120 ° C. for the second heating power is instructed and S4
65, together with the result of the burn mode 1, the second heat power = weak instruction, S466, ULT = 20 (S467), LLT =
3 (S468), JST <HT2 is judged whether the value of the combustion time calculation is smaller than the minimum combustion time HT2 in the H mode, S469, and in that case, JST = HT2 is changed to S4.
70, including the case of being large, go to * A in FIG. 32 S47
1.

Here, JST = F × TK + θ1 in the calculation of the combustion time from the start of combustion, and when F1 and θ1 are in this mode (when the fillet starts to be hot and the degree of charring is strong), the reference fish of this mode is used. The most appropriate baking coefficient,
This coefficient also needs to be changed depending on the selection of the charcoal.
In addition, this coefficient must be determined for each fish species mode.

FIG. 43 shows the flow of the I pattern (dried fish / high temperature start). As for I pattern S472, is the sensor temperature 10 ° C higher than the starting temperature (TSO + 10 ° C) <TH?
Judges, S473, waits for that to happen, 10 ° C from the start
The time when it becomes (T10 = TH) S47
4. Then, it is determined whether the burn mode 1 is S475, and at that time, the combustion time is calculated (JST = I1 × T10 + ι1).
S476, the switching temperature to the second thermal power K2T = 140 ° C. is set to S477, and the process proceeds to the next. If not, it is determined whether or not the burn mode 2 is S478, and at that time, the combustion time is calculated (J
ST = I2 × T10 + ι2) S479. If not, the burn mode is set to S480, the combustion time is calculated (JST = I3 × T10 + ι3) S481, and the process proceeds to the next step.

When the combustion calculation of the burning modes 2 and 3 is completed, the switching temperature K2T = TSO + 10 ° C. for the second heating power is instructed and S482, together with the burning mode 1 result, the second heating power = low is instructed. S483, ULT = 20 (S484), L
LT = 20 (S485) is instructed, and the burning time calculation value is
Is it less than the minimum combustion time IT2 in I mode or JST <IT
Two judgments are made in S486, in which case JST = IT2 is replaced with S487, and S488 going to * A in FIG. 32.

Here, JST = F × TK + ι1 in the calculation of the combustion time from the start of combustion, and F1 and ι1 are the reference fish in this mode when in this mode (when the fillet starts to be hot and the degree of charring is strong). The most appropriate baking coefficient,
This coefficient also needs to be changed depending on the selection of the charcoal.
In addition, this coefficient must be determined for each fish species mode.

As mentioned above, the type of fish, the degree of charring,
The most preferable method of the burn-up determination method changes depending on the respective conditions, depending on the temperature inside the starting chamber. Therefore, the method of selecting the most preferable burn-up determination method that meets the conditions from various burn-up determination methods from the matrix can improve the accuracy of the determination method, and thus lead to the improvement of the accuracy of the automatic fire extinguishing time. It is possible to provide an automatic grill in a stable condition.

The above is the description of the burn-up determination method.
Establishing reliability and guaranteeing accuracy by backing up the judgment method is described.

FIG. 44 and FIG. 45 relate to the improvement of reliability, and show the relationship between the slope of horse mackerel and swordfish (in this case, the time between two defined points) and the baking time. The horizontal axis shows the slope (time difference), the vertical axis shows the baking time, and the weight and the slope (time difference) of the horse mackerel and saury are also changed by plotting the time until baking and the slope (time difference). It was done. In the same drawing, there are two groups, but the time difference measurement temperature is changed and described. One is 50-100 ° C, the rest is 1
The gradient is 30-140 ° C.

The thermal power at the time of gradient measurement at 50-100 ° C. was burned at a high level (2200 Kcal / h), and the thermal power was dropped to medium (1700 Kcal / h) at 110 ° C. to obtain a thermal power suitable for grilling a figure fish. In this case, the correlation between the gradient (time difference) and the baking time is shown. When the plotted data group is linearly approximated, an approximate expression at 50-100 ° C. Y = A1X +
It is represented by the approximate expression Y = A2X + B2 of B1 and 130-140. When the gradient (time difference) can be determined, the baking time can be determined. In this case, it can be seen from the value of R ^ 2 that the approximate expression at 50 to 100 ° C. has a better correlation of the baking time in both horse mackerel and saury. Therefore, 50-10
It is necessary and sufficient to determine with a gradient of 0 ° C.

Here, as the method for determining the baking time, (1) the baking time is determined by using a gradient of 50 to 100 ° C. or (2) the gradient of 130 to 140 ° C. is used. To determine the baking time (3) or to determine the time using both gradients.
(1) has already been described in the flow. The same can be applied to the process (2), and a description thereof will be omitted. (3)
The method will be described below.

FIG. 46 is a flow chart using the above (3). 46 is the same as FIG. 32 except for the following, and the description thereof will be omitted by giving the same numbers. The only changes are S299 for switching to the first thermal power and S3 for setting ULT and LLT.
This means that GOSUB burn-up determination 2 (S299-1) is inserted between 00.

FIG. 47 is a flow chart showing the contents of the burn-up determination 2 subroutine. Wait until the sensor temperature has reached 130 ° C, 130 <TH determination is made at S490, and then store the time when 130 ° C is obtained at T130, S49.
1 and then 140 ° C, whether 140 ° C or not is judged and S49
2. Wait until it becomes, store the time when it reached 140 ° C. in T140, S493, calculate the time difference T14 = T140
-T130 (S494), and then calculates the baking time estimated from the 140 ° C. gradient (second determination) JST2 = a1.
× T14 + b1 (S495). Next, call the automatic fire extinguishing time JST calculated from the gradient of 50-100 ° C (first judgment), JST1 = JST (S496), new JST
Calculate (automatic fire extinguishing time) JST = (JST1 + J
ST2) / 2 (S497), RET (S498) to return to the original state with this JST.

The above is 50-100 ° C., and 130-140
It is a method of calculating the automatic fire extinguishing time using both gradients of ° C.

Of course, although omitted in the above description for the sake of space, the method of selecting the fish species and changing the automatic fire extinguishing time by inputting the brown eye key is as described above. Further, the low temperature gradient and the high temperature gradient are proportionally calculated,
Weight calculation (Since the low temperature gradient is relatively accurate,
It is also included in the gist of the present invention even if the specific gravity is calculated at about 6: 4).

According to the above invention, as compared with the case where the baking time is calculated by the low temperature gradient alone, (1) Abnormality at the time of measuring the low temperature gradient (the user temporarily opened the door during the gradient measurement, the oil flew away). The risk of slope measurement is reduced as a countermeasure against momentary burning. (2) With the above, the probability of burning to the same extent at any time is high, and the reliability of the user is improved. There is an effect. The effect of this backup is 0 or 1.
From the perspective of the above, it has a great effect to improve from the unreliable state where suddenly the grilled figure appears or the situation is ◎, to the state where it is a little poorly made, and in the development of the automatic grill Is an indispensable element of invention.

Next, the improvement in the accuracy of burn-up determination by correcting the gradient measurement will be described.

FIG. 48 shows an example of an error correction method for calculating the baking time based on the starting temperature. It is a graph showing room temperature on the horizontal axis and time on the vertical axis, and showing the time to reach 100 ° C. when changing the room temperature in the empty state with one fish and three fish with 180 g of horse mackerel. Square plots represent raw data and triangular plots represent temperature-corrected plots.

The raw plot naturally has a short time lag in reaching the temperature of 100 ° C. depending on the room temperature. When calculating the grilling time, it is necessary to remove the effect of room temperature and to know how much fish is in the refrigerator, and to correct the starting temperature for that purpose. The present invention aims at performing room temperature correction, and as an example of the method, first, first-order approximation of a plot of raw data is performed, and y =
-2.8322x + 375.66 is obtained.

Here, based on the obtained temperature correction coefficient of 2.8322, room temperature correction y = (individual data)-(standard temperature-starting temperature of each data) × temperature correction coefficient (2.832)
As 2), all the data are corrected to the standard temperature again, and plotted in the triangular shape at 35 ° C.

The above shows an example of the correction, and shows a method of obtaining the corrected standard temperature reaching time of 100 ° C. This means that when the starting room temperature is constant,
It will be easier to understand the characteristics of the fish because the time to reach 00 ° C will be converted into a certain temperature and handled. This is shown in Figure 49 below.
Becomes clearer.

In FIG. 49, the abscissa represents the number of animals and the ordinate represents the time required to reach 100 ° C., the raw data, the above-mentioned correction data (expressed as result function correction) and another correction method “start”. These are three plots of “30 ° C. correction 100 ° C. time”. The new correction method is to adjust the start temperature to the specified temperature (30 ℃), and adjust it to 30 ℃.
The data has been modified so that it will start (for example, 10 ℃
If it is started, 30/10 = 20, and this 20 is added to the data for handling.)

As shown in the figure, in the raw data without temperature correction, there is no classification of empty, 1 and 3 animals, but by performing temperature correction, the target number discrimination becomes clear, By clarifying the number of animals, the baking time can be calculated accurately.

(1) In the raw data, it is difficult to distinguish between 3 animals and 1 animal, and R ^ 2 = 0.6203.

(2) In the function correction method, the accuracy is improved, the discrimination is almost accurate, and R ^ 2 = 0.8906.

(3) The 30 ° C. correction method has the highest accuracy and can be discriminated, and R ^ 2 = 0.9493.

Therefore, in order to calculate the baking time, it is indispensable to perform room temperature correction and perform an accurate number (judgment determination). The methods (2) and (3) show that the method for estimating the baking time can be corrected regardless of whether it is the gradient measurement or the time measurement. In particular, in (2), since the numerical value obtained as an experimental value in advance can be corrected by corrective correction to the result obtained, the application range is wide and the baking time accuracy can be improved.

An example of means for improving the accuracy of the baking time by incorporating the above-described correction method into the baking time calculation will be described below.

FIG. 50 is a flow chart showing the starting temperature correction means (measurement temperature conversion system). Calculate the difference between the starting temperature (TSO) and the standard temperature (STT) and calculate SA = STT-TSO (S5
00), then it is judged whether the sensor temperature (TH) + SA has reached 100 ° C., S501, and waits until it reaches 100 ° C. 10
The time (T100) when the temperature reaches 0 ° C. is memorized, S502, the first heating power switching temperature K1T-110 ° C. is instructed and S50.
3, 1st thermal power = “medium” is instructed S504, 1st thermal power switching upper limit time ULT = 20 is instructed S505, 1st thermal power switching lower limit time LLT = 3 is instructed S506, then it is determined whether the burning mode is 1 S507, in which case burn time calculation JST = J1 × T100 + κ1 is calculated S50
8, if not, it is determined whether the burn mode is 2, S50
9. In that case, combustion time calculation JST = J2 × T100 +
κ2 is calculated in S510, and if not, it is determined that the burn mode is 3, S511, burn time calculation JST = J3 × T1
00 + κ3 is calculated S512, the second heating power switching temperature K2T = 140 ° C. is instructed including the cases of the burning modes 1 and 2, S513, the second heating power = “weak” is instructed, and S514 is returned to the original S515.

The above contents are to determine the correlation time between the length of time to reach 100 ° C. and the baking time of the object to be baked, which is correlated with the length, by experiment, and determine the time for the grill to burn. The means for accurately determining the baking time of the contents by correcting the starting temperature difference at this time is shown. The citation uses a modification of the E pattern, but each pattern has the same concept, and has an example, and other patterns are omitted for the sake of space.

Further, FIG. 51 shows an example of the starting temperature correction method 2 (function correction method). The start temperature is stored, TSO = TH (S516), and the sensor temperature is 50.
After waiting for the temperature to reach ℃, S517 stores the time when it reached 50 ℃ (T50) = JS (S518), and the sensor temperature is 1
After waiting for the temperature to reach 00 ° C., S519, the time when the temperature reaches 100 ° C. is stored (T100) = JS (S520), and gradient calculation TH1 = (T100−T50) is calculated S521.
After that, TH = TK1− (standard temperature−TSO) × temperature correction coefficient S522 for performing temperature correction calculation. In the present invention, the standard temperature is assumed to be in the range of 0 to 50 ° C. at the start of room temperature, but the standard temperature is listed, but there is no problem unless the values are far from each other. The meaning of this correction has been explained in the previous figure. Since the subsequent processing has been described in advance, a number is attached and omitted.

By this correction, it is possible to improve the accuracy of the grilling time and perform reliable automatic cooking of the grill. In addition,
Although the citation uses the A pattern, each pattern has the same concept, and has an example, and other patterns are omitted for the sake of space.

Although the burner is used as the heat source in this embodiment, an electric heating means such as a heater or an induction heater may be used as the heat source.

[0203]

As described above, according to the present invention, the temperature sensor for measuring the temperature in the grill chamber, the heat amount control means for controlling the heating amount, and the heat amount control according to the temperature state of the temperature sensor. Drive control means for controlling the means, wherein the drive control means has a baking determination means for calculating at least the baking time from the degree of temperature increase of the temperature sensor, and the baking determination means is for increasing the temperature of the temperature sensor. In addition to calculating the heating time from the degree, the judgment coefficient of the burning judgment is variable depending on the temperature of the temperature sensor at the start of heating, and the behavior of the temperature rise of the temperature sensor is analyzed to make an accurate baking judgment. Since the heating amount is set automatically and the baking time is set, it is possible to provide a stable automatic grill with a constant baking.
