Figure 11 is the 1st flow chart of the control of cooking of expression embodiment of the invention band rice-cooking function gas furnace.Figure 12 is the 2nd flow chart, and Figure 13 is the 3rd flow chart, and Figure 14 is the 4th flow chart, and Figure 15 is the 5th flow chart, and Figure 16 is the 6th flow chart, and Figure 17 is the 7th flow chart.

Below, describe with reference to Figure 11 to Figure 17, suitably use the block diagram of Figure 18, the curve map of Figure 19 to Figure 25 to describe.

As shown in figure 11, when cooking the control beginning, shown in step 201, the firepower of standard burner 103 is controlled to be strong fire.Strong fire described here for opening under the state as previously mentioned, is the firepower of using the choke valve 1121a corresponding with firepower adjusting rod 121a to regulate at magnetic valve 135.In addition, as previously mentioned, the adjusting situation of the choke valve 1121a that control part 143 nonrecognition are corresponding with firepower adjusting rod 121a, therefore just the opening or closing of magnetic valve 135 that control part 143 can be discerned, need carry out following pot and plant differentiation etc.

Then, firepower keeps catching fire strong, in step 202, carries out initial temperature and judges.This judgement is to judge whether to reach 60 ℃.If be judged as more than 60 ℃, then enter step 204, if be judged as 60 ℃ of less thaies, then become the hot start mistake in step 203.That is, control part 143 becomes the state of closing with safety valve 133a from opening state, with standard burner 103 fire extinguishings.

When entering step 204, measure and store the data Δ t of the pot kind that is used to differentiate the pot that is heated by standard burner 103 ₁Data Δ t ₁By standard burner 103 heat the pot temperature rise to 70 ℃ of required rise time from 60 ℃.In this step 204, be measured to 70 ℃ with how long by timer 151 instrumentation temperature sensors 107 from 60 ℃, 149 these times of identification of judegment part and being stored in carry out in the memory 155.

Then, in step 205, judge whether more than 90 ℃.If more than 90 ℃, then be heated pot and temperature equilibrium may occur.Therefore, when reaching more than 90 ℃, begin to measure the processing of temperature equilibrium in step 206.Temperature equilibrium is to measure by the action of the temperature equilibrium determination section 153 in the control part 143 shown in Figure 180.Be provided with equilibrium temperature test section 161 in the temperature equilibrium determination section 153, equilibrium temperature test section 161 carries out the processing of step 207.

Figure 19 is the curve map that is used to illustrate the processing that determines equilibrium temperature.

As shown in figure 19, the processing of equilibrium temperature decision is by carrying out every 15 seconds data samplings to temperature sensor 107.Satisfying following condition 1 and at 2 o'clock, equilibrium temperature is determined.

1-2 ℃≤T of condition _N-T _N-2≤+2 ℃

The continuous T that satisfied condition 1 o'clock for three times of condition 2 _E3, T _SFor ,-2 ℃≤T _E3-T _S≤+2 ℃

In the formula, T _NBe up-to-date mensuration temperature data, T _N-2Be T _N2 times before data, T _E3Be the T that satisfied condition 1 o'clock for the 3rd time _N, T _SBe the T that satisfied condition at first 1 o'clock _N-2

Condition 2 is set up T _E3Be decided to be equilibrium temperature.When equilibrium temperature is determined, only at T _E3When lower, equilibrium temperature is changed to T than the equilibrium temperature that has been determined _E3

Then, when step 207 equilibrium temperature had been determined, entering the common control treatment step of cooking was step 208, when equilibrium temperature is not determined, enters step 209.

Step 209 is whether the mensuration temperature of judging temperature sensor 107 is the determining step more than 140 ℃, if be not more than 140 ℃, then to return step 207, if be more than 140 ℃, then enters step 210, becomes the lack of equilibrium error.Usually, although equilibrium temperature is determined before 140 ℃, during sometimes as the low pot of the pyroconductivity of using olla etc. poised state produce or can not get poised state in the temperature more than 140 ℃.At this, benchmark, the about 140 ℃ reason of use as the lack of equilibrium error are described.It is the reasons are as follows: even when also having thickness at aluminium thick under the situation of the metal pan of common aluminium etc. and so on, near about 130 ℃, also produce the situation of temperature equilibrium, the situation of distinguishing this kind situation and using low pot such as the pyroconductivity of olla etc. under the thick situation of pot thickness as the lack of equilibrium error.Among Figure 20, show the situation that before 140 ℃, can see equilibrium temperature and can't see equilibrium temperature.Aluminum pot, enamel pan etc., the moment temperature equilibrium that equilibrium temperature is preferably in H1 can be detected, for example, the pot low as the pyroconductivity of olla etc. and so on, if can detect under the situation that 140 ℃ of temperature equilibrium do not produce temperature equilibrium yet, in 140 ℃ (H2) fire extinguishing constantly even become common pot.Fire extinguishing is that the safety valve 133a by the control signal of accepting control part 143 shown in Figure 8 becomes the state of closing and carries out from opening state.Like this, carry out the error control that control stops to heat as lack of equilibrium by control part 143.In addition, when control part 143 carried out error control, the portion that reports 171 that accepts control part 143 signals informed the user to this state that carries out error control.Report is to ring with the lamp demonstration or with buzzer to carry out.Its result, the user can know situation about can not cook, for example again after the igniting, the user can take some measure of finishing the usefulness of cooking of manual firepower adjusting etc.

In addition, but operated under the situation of the button 117 of cooking carrying out oil plant reason, also do not detected temperature equilibrium, when 140 ℃ the moment,, and reported by buzzer by flame-out.Thus, the user can switch to correct cooking mode by changing operation Fried Fishes button 115, proceeds the cooking.

The H3 of Figure 20 is not fire extinguishing but equilibrium temperature decisive time when continuing to be heated of expression hypothesis pot.Control as lack of equilibrium, be safety valve 133a to be in the state of closing and fully flame-out, in addition, control as lack of equilibrium, also can close magnetic valve 135 earlier firepower is become weak fire (350Kcal), make safety valve 133a be in the state of closing again later by the stipulated time that timer produced warp not shown in the figures and make it flame-out 140 ℃ the moment.Do like this be because, though some are 140 ℃ of stages that switch to weak fire, also have and finish the situation of cooking (can be weaker) basically though compare mouthfeel with the situation of the metal pan of using aluminum pot etc., after switching to weak fire, by the stewing ripe time through the stipulated time, what can make mouthfeel better.

In addition, the lack of equilibrium control that continues as cooking under the situation of low pot such as the pyroconductivity that makes olla etc., as shown in figure 33, control part 143 possesses timer 151, control part 143 carries out the lack of equilibrium control according to flow process shown in Figure 34, even before about 140 ℃, can not obtain under the situation of temperature equilibrium, also can finish cook in, guarantee taste.

Specifically, by enter step 210a from step 209, the lack of equilibrium control that making cooks is continued is begun, in step 210a because of before 140 ℃, not detecting equilibrium temperature, and must not obtain temperature equilibrium, firepower switches to weak fire (about 350Kcal) from strong fire (about 1300Kcal), and this switching becomes the state of closing by control part 143 with magnetic valve 135 and carries out.

Here, why with 140 ℃ of switchings of carrying out to weak fire, be because when distinguishing the thick metal pan of olla etc. and pot thickness as described above, residue has under the state of sufficient moisture the suction of rice, the step of seething with excitement is begun in the pot of olla etc.

In addition, as previously mentioned, by control part 143 magnetic valve 135 is become the state of closing, firepower becomes weak fire, by control part 143 magnetic valve 135 is become 135, and firepower becomes and is strong fire, following also be same.

And shown in step 210b, the heating under the weak fire continued 5 minutes.Even the heating of this weak fire of 5 minutes is suction, the boiling step of the rice that carries out under poised state for the metal pan of carrying out aluminium etc. under the situation of using olla etc. effectively.In step 210c, firepower turns back to strong fire, shown in step 210d, up to crossing 155 ℃ with the strong fire step of cooking, when surpassing 155 ℃, switches to weak fire once more, the step of cooking rice over a slow fire.

In step 210f, differentiate whether temperature is more than 160 ℃.Why need such differentiation, although the firepower of cooking rice over a slow fire in step 210e is switched to weak fire, water evaporates is in 7 minutes described later, and temperature rises will produce the excessive paste that boils.

When temperature rises to more than 160 ℃, at step 210g firepower is switched to strong fire, after the cooking of the strong fire that carries out 20 seconds shown in the step 210h, flame-out and finished and cooked.

In addition, when temperature does not become more than 160 ℃ in step 210f, enter step 210i.Carry out closed-loop process, can not become more than 160 ℃, during through 7 minutes, firepower is switched to strong fire at step 210j, after cooking with the strong fire in 60 seconds shown in the step 210k, flame-out and finish and cook.

In addition, in the processing of step 210h, with time of strong fire during as 20 seconds, because of considering that reaching 160 ℃ of moisture evaporates, so, set 60 seconds weak points of strong fiery time ratio of step 210k, be in order to prevent to boil paste.

Figure 35 represents the curve map corresponding to the processing of Figure 34.H2a is the firepower switching instant to weak fire switching of step 210a, H2b is the firepower switching instant that the Xiang Qianghuo of step 210c switches, H2c is the firepower switching instant to weak fire switching of step 210e, H2d is the firepower switching instant that the Xiang Qianghuo when step 210f has entered step 210g switches, and H2e is that cooking when step 210g has entered into step 210h finished constantly.H2f has entered into the firepower switching instant that the Xiang Qianghuo of the situation of 210i, 210j switches from step 210f, and H2g is that cooking when step 210j has entered step 210k finishes constantly.

In addition, same with situation described later, cooking at the end, report by buzzer 171.

In addition, report portion 171 and also can change the mode of reporting by the difference of using bright lamp mode, buzz.But, also can be provided with and report portion corresponding to the control of different respectively error, only can select arbitrarily with lamp, with buzz, lamp and buzz combination, the display mode of lamp, the mode etc. of ringing of buzzer.

Then, in step 208, carry out the pot of standard when cooking pattern and plant and differentiate data Δ t ₂Mensuration and storage or the firepower when cooking pattern fast and the amount of cooking differentiate data Δ t ₂Mensuration and storage.Δ t ₂Be to detect the elapsed time of back to equilibrium temperature+6 ℃ from equilibrium temperature, be considered as pot temperature equilibrium during.When standard is cooked pattern, the temperature equilibrium determination section 153 of Fig. 6, accept expression by judegment part 140 and detected this signal of equilibrium temperature, make timer 151 actions, when temperature sensor 107 was measured equilibrium temperature+6 ℃, the instrumentation time of determination section 153 identification timers 151 also was stored in it in memory 155.During the pattern of cooking fast, the judegment part 149 of Fig. 6 carries out same action.

Then, in step 211, being selected to of the pattern of cooking can not switching state.Otherwise, back before step 208 end from the control beginning of cooking, whenever by the key 117 of once cooking, can be from switching to standard fast or switching to fast from standard.Promptly, as shown in Figure 9, preference pattern is switched in preference pattern switching part 167 operation by the key 117 of cooking before step 211, by the temperature equilibrium determination section 153 that carries out step 208 processing the signal that the expression poised state ends is exported to preference pattern switching part 167, preference pattern switching part 167 is after step 211, even be operated can not switch mode for the key 117 of cooking.

This is in order to ensure reliability, because in the later control of step 211, be different for mode standard and quick mode, the pattern switching during different controls are handled is easy to generate misoperation.In addition, can carry out the pattern switching before step 211 is because usually cook unchangeably with the pattern of being not only initial selection, and allows the switching of pattern as much as possible, thereby makes device have pardon, can improve the convenience of device.This is because there is following situation to exist, especially owing to use standard burner to cook, the number of the burner that can use is few, hampers when hindering and other cooking had, user's mood is changed to be want to switch to quick mode from mode standard, and cooked as soon as possible.

In addition, though can only choice criteria pattern and the such two kinds of patterns of quick mode, can consider that also food boils other various patterns that wait together, even in this case, also before common control, the setting of cooking can be switched,, the switching of pattern can not be carried out from different control.In addition, the switching of pattern, for example under the situation that 3 kinds of patterns are arranged, before common control, needn't determine changeable or not changeable to all mode, can determine earlier that also a pattern and other two patterns are changeable or not changeable, determine between them changeable or not changeable to other two patterns more afterwards.

Then, judge that the pattern of selecting of cooking is mode standard or quick mode in the step 212 of Figure 12.If mode standard then enters step 213, if quick mode then enters step 219.Step 213 is steps that pot is planted differentiation 1, according to the Δ t that is stored in Fig. 5 memory 155 ₁Value is more than 75 seconds or discontented 75 seconds, differentiates the material that is heated pot.That is, judegment part 149 is according to the data Δ t that is stored in the memory 155 ₁Value is differentiated the pot of high material such as the pyroconductivity that is heated pot that pot is the low material of pyroconductivities such as enamel, stainless steel or aluminium, culture pot.More than 75 seconds the time, enter step 214, pot is planted the pot of being differentiated for being the low material of pyroconductivity.Less than entered step 215 in the time of 75 seconds, and it is to be the pot of the high material of pyroconductivity that pot is planted by differentiation.

Then, plant when being the high material of pyroconductivity, enter step 216, carry out pot and plant differentiation, its result, data Δ t when differentiating in step 215 for pot ₂Less than entered step 217 in the time of 230 seconds, and being judged as pot kind differentiation 1 is mistake.As data Δ t ₂Be more than 230 seconds the time, enter step 218, be judged as pot and plant that to differentiate 1 be correct.That is, the judegment part 149 of Fig. 5 is according to the data Δ t that is stored in the memory 155 ₂Differentiating pot once more plants.Why will carry out this differentiation once more, be because differentiate 1 not necessarily correct cause in the pot kind of step 213.Therefore,, the correctness that step 213 is differentiated can be confirmed,, more correct control can be carried out even mistake also can be revised by differentiating once more.In addition, step 217 be judged as pot plant to differentiate 1 be wrong time, entering that heated pot is judged as is the step 214 of the low material of pyroconductivity.

Then, be judged as when being the low material of pyroconductivity in step 214, enter step 236, the firepower of standard burner 103 switches to weak fire from strong fire.This switching is that the judegment part 149 by Fig. 5 is given to magnetic valve 135 according to differentiating the result with control signal, and magnetic valve 135 becomes the state of closing and carries out from opening state.Even magnetic valve 135 is for closing state, as shown in Figure 4, the Gas Pipe 129 that is being connected with standard burner 103 is being branched, and combustion gas still can be supplied with.The firepower here is about 350kcal/h.

In Figure 21, drawing with from the corresponding curve of the processing of step 213.At the curve that is positioned among the curve of upper, middle and lower, be (pot that pyroconductivity is low) corresponding curve when having advanced to step 213, step 215, step 216, step 217, step 214, step 236.Curve in the middle of being positioned at is (pot that pyroconductivity is high) corresponding curve when advancing to step 213, step 215, step 216, step 218.Curve under being positioned at is (pot that pyroconductivity is low) corresponding curve when having advanced to step 213, step 214, step 236.Wherein, H4, H5 are the moment that equilibrium temperature is determined, H6, H7, H8 are that temperature equilibrium is ended constantly, and H6 and H8 still are firepower switches to weak fire from strong fire the moment.

Return the step 219 of Figure 12,, carry out the differentiation of the amount of cooking of the firepower of standard burner 103 and pot and handle in step 219.This differentiation is to differentiate the data Δ t that is recorded in the memory 155 by the judegment part 149 of Fig. 6 ₂Whether undertaken by 230 seconds more than 230 seconds or not.If, then enter step 220 more than 230 seconds, think that the evaluation of estimate of firepower and the amount of cooking is little, in step 221 from the switching temperature T of strong fire to weak fire _KBe set at 145 ℃, the weak fire time t that cooks _jBe set at 2 fens, baking is set at nothing.If less than 230 seconds then enters step 222, the evaluation of estimate that is judged as the firepower and the amount of cooking is big, in step 223, from strong fire to weak fiery switching temperature T _KBe set at 135 ℃, weak fire time t _jSet 3 fens, baking is set at nothing.

Then, after step 221 or step 223, in the step 224 of Figure 15, whether the mensuration temperature of judging temperature sensor 107 is at switching temperature T _KMore than.If not enough T _K, then enter the processing of step 232, if be T _KMore than, then entering step 225, the firepower of standard burner 103 switches to weak fire from strong fire.The switching here is also by carrying out magnetic valve 135 from opening to be controlled to be to close.Therefore, firepower is about 350kcal/h.In step 226, the time of the cooking t of weak fire _jBeginning.

Then, enter the processing of the step 227 of Figure 16, judged whether baking, and judge whether pot is planted is the high material of the thermal efficiency.Owing to all do not have baking in step 221 and step 223,, judge from beginning and whether passed through the MAX time so enter step 228.The MAX time here is the time of cooking the fast MAX data promptly 20 minutes that are stored in the data store 169 of Figure 10.If passed through 20 fens, the step 231 that then enters Figure 17 is if not through 20 minutes, then enter step 229.In step 229, judged whether to pass through the time t that sets _jThe t here _jBe 2 minutes or 3 minutes in step 221 or step 223 setting.t _jNot not at the end, return step 228, t _jAt the end, enter step 230.In addition, t _jIt is the time data of cooking fast that is stored in the data store 169 of Figure 10.The time data of cooking is not the time after being set to start with, but is set to the weak fire time after switching from firepower.This is to be used for the stewing ripe time.Judge after beginning whether passed through the MIN time in step 230.The MIN time is the time of cooking the fast MIN data in the data store 169 of Figure 10, is set at 12 fens.If do not pass through the MIN time, then circular treatment.If passed through, then enter step 231.

By the processing of step 228, step 229, step 230, if t _jThe MAX time that at the end is engraved in and MIN between the time, then, cooking to finish is t _jAt the end.If t _jEnd and constantly crossed the MAX time, then cook the time of finishing into MAX.If t _jThe not enough MIN time, then cooking is performed until the MIN time.Like this, also to carry out the MIN time, can guarantee certain mouthfeel even cook fast.

The step 231 of Figure 17 is to judge the step that has or not baking, does not have baking owing to all be judged as in step 221 and step 223, so, the last processing of cooking and finishing.

In Figure 22, drawing the processing corresponding curve later with step 219.The curve that is positioned at is (firepower, boil and have a good appetite) corresponding curve when having proceeded to step 219, step 222, step 223.Curve under being positioned at is (firepower, boil and have a poor appetite) corresponding curve when having proceeded to step 219, step 220, step 221.Wherein, H9 is the moment that equilibrium temperature is determined, H10, H11 are that firepower switches to the weak fiery moment from strong fire, and H12 and H13 are the moment of fire extinguishing.H10 is corresponding to 135 ℃, and H11 is corresponding to 145 ℃.Changing switching temperature in this wise is because the evaluation of estimate difference of the firepower and the amount of cooking, the also different cause of degree of zoom paste easily.In addition, all differentiations of aftermentioned mode standard are not carried out, and this is because in quick mode, the cause that the time ratio mouthfeel is preferential.

Below, the situation of the step 232 that enters Figure 15 is described.In step 232, judge from beginning and whether passed through the MAX time.If process is not returned step 224, carry out circular treatment.If passed through, then enter step 233, time expand.Here, why wanting time expand, is because temperature T _KBe that firepower is switched to the temperature of weak fire from strong fire, this temperature is the temperature that expression water evaporates rice is cooked ripe, if do not reach this temperature, also wants time expand even passed through the MAX time, until rice is cooked ripe.In step 234, judge from beginning whether passed through 30 fens, if not through 30 minutes, return step 224 and carry out circular treatment, if passed through 30 fens, then enter step 235, become the time error of cooking.Even prolong in step 233 and to cook the time, if from beginning also through 30 minutes, expression has produced that certain is unusual, at this moment, the control part 143 of Figure 10 carries out error control, and safety valve 133a is become the state of closing and fire extinguishing from opening state.Then, report portion 171, this is reported the user unusually from the signal that control part 143 acceptance " have unusual ".Here, from beginning back 30 minutes, be the time lengthening MAX data of cooking that are stored in the data store 169 of Figure 10, when cooking pattern fast, the MAX data are 20 minutes.Confirm as and prolonged 10 fens.Like this, by time expand, that can guarantee to boil cooks the time, surpassed prolong in limited time, report unusually, guarantee security.Therefore, during error control, the user can take to control corresponding countermeasure with this error.

About error control, with illustrated in fig. 18 same,, also can close magnetic valve 135 earlier except safety valve 133a is in the state of closing, through behind the certain hour, 133a is in the state of closing with safety valve.In addition, about reporting portion 171 also with illustrated in fig. 18 identical.

Below, the situation that enters the step 237 of Figure 13 from the step 236 of Figure 12 is described.In step 237, judge whether firepower was passed through 90 seconds after strong fire switches to weak fire.During not through 90 seconds, carry out circular treatment, when having passed through 90 seconds, enter step 238, carry out the processing that pot is planted differentiation 3.It is whether the temperature that is heated pot when having passed through 90 seconds is to carry out more than 127 ℃ that pot plant to differentiate 3.That is, whether the judegment part 149 of Fig. 5 passed through the temperature when having passed through 90 seconds by the mensuration identification of temperature sensor 107 90 seconds after by timer 151 judgements switch-over control signal being exported to magnetic valve 135.If more than 127 ℃ the time, judegment part 149 is judged as pot and plants that to differentiate 1 (2) be correct shown in step 239, if 127 ℃ of less thaies then shown in step 241, are judged as pot and plant that to differentiate 1 (2) be wrong.Before step 238, because planting, pot differentiated for being the material of low-thermal conductivity, so in step 239, keep this differentiation, being modified in step 241 is the high material of pyroconductivity.

When step 241 has found that pot is planted differentiate wrong, in step 242 control is turned back to originally, firepower switches to strong fire from weak fire.In step 243, switch to the temperature T of weak fire from strong fire _KBe set at 135 ℃, the time of the cooking t of weak fire _jBe set at 7 fens, baking is set at nothing.Be judged as pot to step 239 and plant differentiate when being correct, enter step 240, the weak fire time t that cooks _jBe set at 5 fens, baking has been set at.Stoving time t _cIt is 30 seconds.

Differentiate about the pot kind, conclusion is got up and is, carries out the 1st differentiation (pot is planted and differentiated 1) in step 213, differentiates (a pot kind differentiates 2) once more in step 216, can carry out correct pot basically by this differentiation of 2 times and plant differentiation.Like this, processing and the later processing of aftermentioned step 244 to step 236 differs widely.Wherein, in step 214, being judged as the pot kind is the pot of low-thermal conductivity material, when entering the processing of step 236, carries out pot once more in step 238 and plants differentiation 3.This is because resemble the cause that the pot of low-thermal conductivity materials such as enamel pan, stainless-steel pan burns easily.Like this, after pot kind differentiation for several times, reduced the mistake of differentiating to greatest extent.Then, according to differentiating the results change control of cooking, the control of cooking of good to eat rice is carried out in the abundant heating of not burning.

Above-mentioned is to carry out No. 3 pot kinds to differentiate, but also can only carry out wherein once, perhaps also can make up 2 classes.To this is arbitrarily.In addition, pot is planted and is differentiated data Δ t ₁What adopt is the used time of rising uniform temperature, plants differentiation but also can carry out pot according to the temperature that rises within a certain period of time.That is, pot is at this moment planted to differentiate and is not limited only to temporal information, but carries out according to temporal information and temperature information.In addition, pot is planted and is differentiated data Δ t ₂Be the duration of temperature equilibrium, be originally should the identical equilibrium temperature of instrumentation time, but in fact owing to do not continue with uniform temperature, so, 6 ℃, be considered as temperature equilibrium, but be not limited to 6 ℃ from the equilibrium temperature that detects to rising.In addition, plant to differentiate 3, have more than and be limited to the employing temperature at the pot of step 238 and since with through 90 seconds be prerequisite, so adopt temperature information and temporal information.In addition, in the pot kind judegment part 147 of Fig. 5, be provided with memory 155, in memory 155, storing data Δ t ₁, Δ t ₂This be because, before step 211, owing to can switch to mode standard or piece gang mould formula, so the mensuration of data is different period with judgement period, Δ t ₂Can be used as the cause that pot kind differentiation or firepower and the amount of cooking are differentiated both.At this moment, before common control end of a period period of changeable pattern, available same program is carried out.But, as described later, do not storing data, differentiating the pot kind, when cooking control, needn't store data according to this differentiation result.

After the step 243, enter the step 224 of Figure 15, after the step 240, enter the step 226 of Figure 15.The later processing and the explanation of front are same, and its explanation is omitted.Wherein, the cook time of the cooking MAX data of pattern of standard are 24 minutes and 45 seconds, and the time MIN data of cooking are 14 minutes and 45 seconds, and the time expand MAX data of cooking are identical with the time of cooking fast to be 30 minutes.The weak fire time of cooking during step 240 is 5 minutes, and the weak fire time of cooking of step 243 is 7 minutes.

Among Figure 23, expression enters the corresponding curve of processing of step 237 with the step 236 from Figure 12.The curve that is positioned at is (pot that pyroconductivity is low) corresponding curve when proceeding to step 236, step 237, step 238, step 239.Curve under being positioned at is (pot that pyroconductivity is high) corresponding curve when proceeding to step 236, step 237, step 238, step 241.Wherein, H14 is the moment that firepower switches to weak fire, and H15 is through 90 seconds the moment after firepower switches.Below curve be at the H15 T1 of 127 ℃ of less thaies constantly, so, judge to be transformed to be the high pot of pyroconductivity and to switch to strong fire.In contrast and top curve is to be T2 more than 127 ℃ constantly at H15, so, cook the time with 5 minutes weak fire, constantly switch to strong fire at H17 for baking, the H18 after having passed through 30 seconds puts out a fire constantly.Following curve switches to weak fire constantly at the H16 that reaches 135 ℃, puts out a fire constantly at the H19 that passed through 7 fens.

Then carry out the thick differentiation of pot in step 244.The thick differentiation of pot be Fig. 7 judegment part 149 according to the equilibrium temperature of equilibrium temperature determination section 161 decision of temperature equilibrium determination section 153 more than 114 ℃ or less than carry out for 114 ℃.If more than 114 ℃, then step 245 be judged as the pot thickness be thick, enter step 246, switching temperature T _KBe set at 135 ℃, the weak fire time t that cooks _jBe set at 8 fens.Baking has been set at.Wherein, stoving time t _CIt is 15 seconds.If 114 ℃ of less thaies, then step 255 be judged as the pot thickness be thin, enter step 256.

In step 256, carry out the firepower and the amount of cooking and differentiate data Δ t ₃Mensuration.This mensuration is to be measured to 130 ℃ of required times by timer 151 instrumentation temperature sensors 107 from 120 ℃ to carry out.Measure the back of ending in step 257, carry out the differentiation of the firepower and the amount of cooking.As Δ t ₃Be more than 20 seconds the time, the evaluation of estimate that is judged as the firepower and the amount of cooking in step 258 is little, in step 259, from the switching temperature T of strong fire to weak fire _KBe set at 145 ℃, the weak fire time t that cooks _jBe set at 8 fens, baking has been set at.Wherein, stoving time t _CIt is 15 seconds.When be judged as Δ t in step 257 ₃Less than is in the time of 20 seconds, and the evaluation of estimate that is judged as the firepower and the amount of cooking in step 260 is big, in step 261, from the temperature T of strong fire to weak fire switching _KBe set at 135 ℃, the weak fire time t that cooks _jBe set at 8 fens, baking has been set at.At this moment stoving time t _CIt also is 15 seconds.

Firepower and the amount of cooking differentiation are also carried out in step 219.Step 219 is the patterns of cooking fast, and step 257 is the standard patterns of cooking.The pattern that the judegment part 149 of Fig. 6 is selected according to the key 117 of cooking is selected firepower and the used data Δ t of the amount of cooking judegment part ₂Or Δ t ₃

Like this, differentiated in that step 244 is pot thick.Differentiated at step 257 firepower and the amount of cooking.According to its result, the weak fire time t that cooks _jWith stoving time t _CBe set at identically, but be set at 135 ℃ or 145 ℃ of different like this temperature to the switching temperature of weak fire from strong fire.That is the thick differentiation of pot,, firepower and the amount of cooking are differentiated the setting that the both is used for switching temperature.

After step 246, step 259, the step 261, all enter step 224, pass through aforesaid processing then, enter step 227.In step 246, step 259, step 261 baking is arranged all, and to be judged as all that pot plants be the material of high thermoconductivity, so, step 247 entered.

Step 247 is to differentiate the step that has or not baking.After firepower switches to weak fire from strong fire, differentiate according to whether detecting more than MIN value+7 ℃.That is, the MIN value that the temperature of Fig. 8 reduces some test section 165 detected temperatures is that temperature reduces point, if temperature sensor 107 detects more than this MIN value+7 ℃, then differentiates for nothing at step 249 judegment part 149 and toasts.If the end detects, then differentiate for baking is arranged at step 248 judegment part 149.Detection more than above-mentioned MIN value+7 ℃ is to step 230, at the weak fire time t that cooks by following step 250 _jCarry out before ending, this instrumentation is undertaken by the timer 151 of Fig. 8.Therefore, having or not of baking is to cook according to switch back fire a little less than be judged as at firepower that variations in temperature in the certain hour of expiration carries out.

Below, the temperature of key diagram 8 reduces the processing method of some test section 165.

The data that switch to the temperature sensor 107 behind the weak fire from strong fire were sampled every 5 seconds.When sampled data reaches 4, carry out DT _N-2=T _N-3-T _N-2, DT _N-1=T _N-2-T _N-1, DT _n=T _N-1-T _nCalculating.Wherein, T _nBe the temperature of temperature sensor 107 up-to-date mensuration, T _N-1,2,3Be T _n1,2,3 time before temperature, DT _nIt is the temperature variation between 5 seconds.In addition, satisfying the T that MIN value decision condition is following condition 3 to 6 _nAs T _MinAdopt.

30 ℃≤DT of condition _N-2≤+15 ℃

40 ℃≤DT of condition _N-1≤+15 ℃

50 ℃≤DT of condition _n≤+15 ℃

Condition 6 Tn≤Tmin

Along with new data are constantly sampled, the oldest data are cast out, and carry out same processing.

Like this, detect MIN value by reduced a some test section 165 by the temperature of Fig. 8, judegment part 149 can determine to be not have to toast according to the mensuration temperature that satisfies Tmin+7 ℃ temperature sensor 107 for continuous three times.Why will toast the differentiation that has or not, be because the pot of judging before step 247 is planted, pot is thick, the not necessarily correct cause of differentiation result of firepower and the amount of cooking, and can prevent to burn by making it not have to toast.

Among Figure 25, the baking that is illustrated in step 247 has or not differentiates the different curve of result.To be firepower switch to moment of weak fire from strong fire for H20, H21, and H22 and H23 have passed through the weak fire time t that cooks from H20 and H21 _jThe moment owing to detect more than MIN value+7 ℃ between from H20 to H22, so, in the H22 fire extinguishing, owing at H21 to not detecting MIN+7 ℃ between the H23, so, carry out for baking from of the switching of weak fire at H23 to strong fire.H24 is the moment of passing through from H23 15 seconds, is carried out fire extinguishing.

The MAX time of cooking, the MIN time that begin during from the processing of step 246, step 259, step 261, with step 240 and step 243 similarly, be respectively 24 minutes 45 seconds, 14 minutes and 45 seconds.That is, to the processing of mode standard and quick mode, MAX time that the pattern of setting respectively is common and MIN time.Wherein, the time lengthening of the cooking MAX time, which kind of pattern all is to begin be 30 minutes.169 these times of expression of data store of Figure 10.Like this, every pattern set cook the time, the pattern of can setting is desired, for example make cooking the time of time, mouthfeel isotype feature functions.

In addition, the upper limit of the prolongation of the time of cooking (30 minutes) not necessarily will also can determine the maximum limit of the time expand of each pattern as the common time of all mode.In addition, the MAX time of cooking, the MIN time of cooking need not only judge when step 250, step 230, step 228, also can judge frequently before to the end after the control beginning of cooking.For the prolongation of the time of cooking, can after the control beginning, judge always similarly.

Then, even the result of step 247 when being judged as baking, enters step 252 from step 231, stoving time t _cIn step 253 beginning, extremely at step 254 stoving time t _cCarry out circular treatment before ending, cook and finish.Be judged as when not having baking the weak fire time t that cooks in step 247 _jEnd, cook and finish.

Among Figure 24, represent the processing corresponding curve later with step 244.The curve that equilibrium temperature is the highest is and enters step 244, step 245, the corresponding curve in step 246 back (thickness of pot is thick).The curve that equilibrium temperature is placed in the middle is and enters the corresponding curve in step 244, step 255, step 256, step 257, step 260, step 261 back (thin thickness, the firepower of pot and boil and have a good appetite).The curve that equilibrium temperature is minimum is and enters the corresponding curve in step 244, step 255, step 256, step 257, step 258, step 259 back (pot thickness, firepower and boil and have a poor appetite).Here, whether the thick differentiation of pot of step 244 is being carried out more than 114 ℃ according to equilibrium temperature, but also can be as T3, T4, T5, according to the temperature that is considered as poised state end equilibrium temperature+6 constantly ℃ whether 120 ℃ with on differentiate.H25, H26, H27 switch to the weak fiery moment to firepower from strong fire, and H25 and H26 are corresponding to 135 ℃, and H27 is corresponding to 145 ℃.H28, H30, H32 be respectively from H25, H26, H27 passed through weak fire cook 8 minutes time, switch to moment of strong fire from weak fire for baking, H29, H31, H33 are through stoving time t _cThe moment of (15 seconds) back fire extinguishing.

Cook when finishing, can finish by reporting to cook by buzzer etc.

Beginning from the control of cooking to finish to the control of cooking, when the mensuration temperature of temperature sensor 107 is more than 180 ℃ the time, think that some has taken place is unusual, carry out error control as cutting high level error.The control of this error by safety valve 133a from opening state and become the state of closing and carrying out.

(variation 1)

Figure 26 is also with equilibration time data Δ t when being illustrated in mode standard ₂Flow chart when being used for the differentiation of the firepower and the amount of cooking.

The standard of Figure 12 is cooked in the pattern, data Δ t ₂Only be used for pot and plant differentiation (step 216), but in Figure 26, shown in step 302, be used for the differentiation of the firepower and the amount of cooking.That is, in standard is cooked the pattern and the pattern of cooking fast, data Δ t ₂Plate is used for the differentiation of the firepower and the amount of cooking.

Step 303 is corresponding with the step 222 of Figure 12, the step 246 that enters Figure 14.Step 304 is corresponding with step 220, enters the step 305 corresponding with step 244.Step 306 is corresponding with step 245, enters step 261.Step 307 is corresponding with step 255, enters step 259.

As can be seen from Figure 26, with Δ t ₂Be used for the firepower and the amount of cooking discrimination result, the processing of the processing that the firepower and the amount of cooking are differentiated, the thick differentiation of pot is opposite processing in Figure 26 and Figure 14.
