Description
The application is that denomination of invention is " the long-time heat preserving method of rice and long-time heat preserving type meal pot ", the applying date to be that July 27, application number in 2000 are dividing an application of female case of 00122149.3.
Technical field
The present invention relates to the method for the long-time insulation of rice and the rice cooker that rice can be incubated for a long time.Particularly relate to through 18 hours or 24 hours long like this time, when preventing the decline of rice quality, keeping the rice local flavor, the method for rice insulation and meal pot of implementing this heat preserving method.
Background technology
Nearest rice cooker is except the heater that possesses heating cooker pot when cooking, also possess in the rice cooker pot muff heaters such as electric heater that just burned meal is incubated at a certain temperature and halogen tungsten lamp, therefore, after long-time, can also provide warm rice.In recent years, because the diversity of life style has proposed to require to have 18 hours even 24 hours so long-time functions with the rice insulation.
In rice, sneak into the thermophilic bacillus.This bacillus can not die when about 100 ℃ of the temperature of cooking yet.Again, for the thermophilic bacillus, have brood cell's type and auxotype, when more than 80 ℃, the thermophilic bacillus that exists with the auxotype form reduces, and also the living of brood cell's type.When holding temperature reached 60～70 ℃, the brood cell was germinateed and is become the also breeding of auxotype.Though thermophilic bacillus itself does not have harm to human body, when the viable count of auxotype thermophilic bacillus reaches 10
7Individual/when g was above, rice began to produce peculiar smell.
As the holding temperature that makes rice is more than 80 ℃, can suppress the breeding of thermophilic bacillus.But, rice when being incubated more than 80 ℃, can be accelerated the drying of rice, can lose the local flavor of rice in the short time.Therefore, usually in order to prevent the drying of rice, rice is incubated at about 70 ℃.
As mentioned above, when the holding temperature of rice maintains 70 ℃ of left and right sides, can not prevent the thermophilic bacillus breeding of sneaking in the rice.Usually, the insulation beginning is after 14～15 hours, and the breeding of thermophilic bacillus is accelerated, and the peculiar smell in the rice begins to produce.When namely only only being incubated, can not carry out to rice the long-time insulation of 18 hours even 24 hours.
The technology of the flat 9-276134 communique record of JP has been proposed here.This technology after after the rice insulation beginning about 5 hours, makes the heater action of the usefulness of cooking, and the rice in the rice cooker pot is heated to more than 80 ℃ again, suppresses thus the breeding of the thermophilic bacillus that exists with auxotype.According to this technology and since only the short time heat more than 80 ℃, can not make the drying acceleration of rice, on the other hand, can suppress the breeding of the thermophilic bacillus that exists with auxotype.
Again, this communique also proposed, and made approximately the method for the heater perseveration of the usefulness of cooking after rice insulation beginning every 5 hours.Like this, usually insulation about 70 ℃, be heated to more than 80 ℃ intermittently, thus, can suppress the drying of rice, and when suppressing the breeding of thermophilic bacillus, can be incubated for a long time rice.
The technology of the flat 9-276134 communique record of JP is to heat in approximately per 5 hours 1 time ratio again.Under the situation of this technology for insulation in 24 hours,, heat again through 4 times at the 5th hour, the 10th hour, the 15th hour and the 20th hour.Experimentize by actual,, yet also have this situation to take place even make and shorten each heat time heating time again having suppressed the drying of rice, when carrying out 4 heating again, can impel the rice drying, particularly near the bottom in meal pot pot, the dry of rice significantly increases, and it is hard to become.Again, it also is important save using the energy, and in order to realize 24 hours insulation, must carry out 4 heating again.
Summary of the invention
The 1st aspect of the present invention is rice to be incubated enough number of times of heating more still less for a long time.
Secondly, the 2nd aspect of the present invention is described.The long-time insulation switch that possesses in the meal that has pot has only when the user operates this long-time insulation switch, just heats in insulation again.For this rice cooker, before pressing long-time heat-insulation switch, only only insulation is not heated again.For the rice cooker of this form, sometimes after meal has burnt down, through the long duration, just operate long-time heat-insulation switch.For example, the rice in the insulation should be eaten up when lunch originally, and had stayed beyond exceeding one's expectations a lot, will be incubated again till supper like this, for such situation, through the long duration, just operated long-time heat-insulation switch after meal burns down.
Rice cooker in the past when operating long-time heat-insulation switch, makes the timer action, therefore operates long-time heat-insulation switch later on through 5 hours, heats again.But through the long duration, operate in the situation of long-time heat-insulation switch after making the meal ready, heat time heating time is just too late so again.
The 2nd aspect of the present invention has realized a kind of again heating technique, and it has passed through the long duration after meal burns down, and when operating long-time heat-insulation switch, also can be incubated for a long time.
At last, the 3rd aspect of the present invention is described.The long-time insulation switch that possesses in the meal that has pot has only when the user operates this long-time insulation switch, just carries out the 2nd later heating again in insulation.For this rice cooker, before the long-time heat-insulation switch of operation, only carry out the 1st again heating, after this do not carry out interrupted again heating.For the rice cooker of this form, sometimes the 1st time again the heating after, just operate long-time heat-insulation switch.For example sometimes, a lot eat remainingly owing to the rice in the insulation, therefore operate long-time heat-insulation switch after this, at this moment the 1st time again heating finishes.
Rice cooker in the past when the long-time heat-insulation switch of operation, so that therefore the timer action operates long-time heat-insulation switch afterwards through 5 hours, is just carried out the 2nd time again heating.Often the 2nd time again heat time heating time can be late a lot of for so above-mentioned situation.
The 3rd aspect of the present invention has realized a kind of again heating technique, and it also can be incubated when the long-time heat-insulation switch of operation after the 1st time heating is finished again for a long time.
The 1st aspect of the present invention is just in order to solve, begin to need repeatedly again heating problems through 5 hours again in the technology of heating in insulation, therefore invented 1 rice heat preserving method and the rice cooker of inventing 12.
The heat preserving method of the rice described in the invention 1 is characterized in that, after possessing rice and burning number with the rice insulation after about 70 ℃ step and this incubation step begin, in any moment after through 6～8 hours, make the rice short time maintain the heating steps again in 80 ℃～110 ℃ temperature ranges.
As mentioned above, the viable count when the thermophilic bacillus of auxotype is about 10
7Individual/when g was above, rice began to produce peculiar smell.Here, the present inventor has carried out confirming after the multiple research that shown in the dotted line A of Fig. 3, after 70 ℃ of insulation beginnings, even through about 8 hours, the viable count of thermophilic bacillus also only has an appointment 10
6Individual/g, can guarantee edible to delicious rice.Just, the beginning incubation step is after 5 hours, even do not heat, rice can not produce stink yet again, can eat the rice of delicious food.
Certainly, preferably heated every 5 hours again, the viable count of thermophilic bacillus can be suppressed at than low degree, as shown in Figure 3, if heated every 5 hours, the viable count of thermophilic bacillus can be controlled at about 10 again
2Individual/g.But this moment, be too short the blanking time of heating just again, and for the situation of long-time insulation, again heating times has after this just increased.Again heating technique in the past is from the viewpoint of the breeding of control thermophilic bacillus, heats through the unnecessary too short time again, and the result is that needed again heating times has just increased.
Invent the heat preserving method of 1 described rice, after incubation step begins through 6～8 hours whenever, heat again, make the rice short time maintain in 80 ℃～110 ℃ the temperature range, controlled the breeding of thermophilic bacillus thus, simultaneously, can be incubated for a long time by the number of times of heating more still less.
According to this rice cooker 1 described heat preserving method that carries out an invention, can rice be incubated for a long time in minimum controlling again heating times.
The 2nd aspect of the present invention just in order to realize, passed through later on the again heating technique that the long duration also can be incubated when operating long-time heat-insulation switch for a long time just burn down meal, invented thus 4 heat preserving method and the rice cooker of inventing 15.
Invent the heat preserving method of 4 described rice, it is characterized in that, possess rice burned after with rice insulation at about 70 ℃ step and heating steps again, described heating steps again is, if before the heating again after this insulation has begun the stipulated time constantly, the long-time insulation of operation switch, then heat again and constantly heat again at this, so that the rice short time maintains in 80 ℃～110 ℃ the temperature range, and after this heats constantly again, the long-time insulation of operation switch then heats after the operation at once again, so that the rice short time maintains within 80 ℃～110 ℃ the temperature range.
Here, so-called long-time heat-insulation switch refers to, after meal burns down, and when so for a long time rice being incubated through 18～24 hours, the switch of user's operation.
According to invention 4 described rice heat preserving methods, for example for being left after meal a lot of rice, perhaps burned meal even supress long-time heat-insulation switch after the insulation beginning, also can heat in correct time in the situation that following period of time is not eaten again.
Technology in the past is, because when pressing long-time heat-insulation switch, long-time heat insulation function just begins to work, rise when therefore pressing this long-time heat-insulation switch, timer picks up counting, and through after the stipulated time, makes heater so that heat action again.Thus, begin after the insulation, in the time of be very long, heater moves again, thereby the breeding of the thermophilic bacillus in rice begins, and serious situation is, in the time of the 18th hour or the 24th hour, the thermophilic bacillus has bred the degree of emitting peculiar smell that reaches.

The specific embodiment
Below with reference to accompanying drawing the invention process form 1～5 is described.
(example 1) Fig. 1 is that combustion gas meal pot of expression the invention process form 1 constitutes profile.The electric heater 7 as muff heater of the combustion heater 5 that as shown in Figure 1, the gas rice cooker 1 of example 1 has disposed rice cooker pot 2, the outer container of placing this rice cooker pot 2 that heating such as placing rice hots plate, is installed on the outer container 3 lid 4 that can switch, heater is cooked in the conduct that arranges below rice cooker pot 2 bottoms, the gas burner 6 of this combustion heater 5 of encirclement formation and setting, contact with the bottom surface of rice cooker pot 2 and the temperature sensor 8 that arranges.Near gas burner 6, disposed igniter 9.Again, the top of gas rice cooker 1 disposes the long-time heat-insulation switch 17 of cooking switch 16 and being incubated for a long time after meal in burning-out of cooking.
The utilization control section 11 of cooking is according to the action of the predefined pattern control combustion heater 5 of cooking, the control duration of ignition, burnout time and firepower etc., the action of cooking simultaneously.Utilize muff heater control section 12, burning down after meal, 7 actions of control electric heater, with rice cooker pot 2 interior preservation and controlling in certain temperature.For this example 1, set holding temperature and be about 70 ℃.Utilize combustion heater control section 13, make combustion heater 5 move in the short time, heat again, so that rice becomes 80 ℃～110 ℃.This example 1, setting the afore mentioned rules time is 7 hours.
The insulation action of the gas rice cooker 1 of this example 1 describes by reference Fig. 1, Fig. 4.Fig. 4 is the flow chart of the control procedure after the expression insulation action beginning.For this example 1, in the action time of beginning to cook, according to the heat time heating time that reaches set point of temperature in the rice cooker pot 2 etc., detect the rice amount, the information when utilizing it as the insulation action.The detection of this rice amount is that the control section 11 of cooking by control device 10 carries out.At first, after the release of cooking, begin the insulation action in the flow chart.This insulation is in muff heater control section 12, and one side utilizes temperature sensor 8 to detect the temperature of rice cooker pot 2 bottoms, and one side makes the energising of electric heater 7 gaps and keeps being about 70 ℃ in the rice cooker pot 2.And, the insulation that utilizes electric heater 7 to carry out, even when the combustion heater 5 of following explanation moves, also effect with remaining valid.
As shown in Figure 4, when being incubated action, make the timer action (S101) that does not have expression on the figure, then watchdog timer is also differentiated from beginning insulation in combustion heater control section 13, whether passed through 7 hours (S102), when through 7 hours, then make combustion heater 5 actions, the temperature of meal pot pot 2 is risen rapidly by combustion heater control section 13.For this example 1, the rice amount that in the action of cooking, detects according to the control section 11 of cooking at first, utilize 13 decision heat time heating times of combustion heater control section (S110, S111).After this make combustion heater 5 action (S112, S113, S114) and control, 1 minute (S115) of heating when making rice amount " little ", the rice amount " in " time heating 2 minutes (S116), heat 3 minutes (S117) during rice amount " greatly ".
The situation that regards to down rice amount " greatly " in this example 1 describes.When rice amount " greatly ", the rice temperature is, rice top is about 85 ℃, and rice bottom (near meal pot pot 2 bottoms) are about 100 ℃ (with reference to the 7th hour of Fig. 2), and meal pot pot 2 interior rice temperature are 80 ℃～110 ℃ scope.This moment the thermophilic bacillus in the rice viable count, although be about 10 before the heating again
4Individual/g, but reduced to 10 owing to heating again
2Individual/g following (with reference to the 7th hour of Fig. 3).
In addition, be to constitute like this for this example 1, rice amount " little " and " in " time, also according to separately heat time heating time, make the temperature of rice in 80 ℃～110 ℃ scope.Like this, the rice temperature in when insulation is set in 80 ℃～110 ℃ the scope be because, when the temperature of rice has surpassed 110 ℃, can accelerate the drying of the rice in meal pot pot 2, on the other hand, when the temperature of rice during, the thermophilic bacillus of the auxotype in the rice is enough reduced less than 80 ℃.When the temperature of rice is heated to more than 80 ℃, can make the viable count of the thermophilic bacillus of auxotype reduce to 10
6Individual/below the g, and can prevent that the peculiar smell in the rice from producing and preventing the rice flavescence.
Just, reduce the viable count of thermophilic bacillus, increase the time stop to breed, wish to improve the heating-up temperature of rice, will keep simultaneously the time set of this heating-up temperature must be longer.But too high or heat time heating time is long when the heating-up temperature of rice, then rice is too early dry, thereby makes taste deterioration.On the other hand, in order to prevent producing peculiar smell and flavescence in the rice, as long as make the viable count of the thermophilic bacillus that exists with auxotype reduce at least 10
6Individual/below the g just.Therefore,, reduce the viable count of thermophilic bacillus, just can prevent the peculiar smell in the rice and the flavescence of rice if make the temperature of rice rise to 80 ℃.
Then, utilize combustion heater 5 to heat, process stipulated time (present embodiment is 3 minutes) (S117) makes gas burner 6 flame-out, makes the release (S118) of combustion heater 5 again.Again, after the release that makes combustion heater 5, timer is resetted (S127), return to and utilize electric heater 7 common insulations to move.This result after utilizing combustion heater 5 to heat to finish, in 8 and a half hours after through about 1 and a half hours, can keep the rice in the rice cooker pot 2 to be about 70 ℃ again.
As mentioned above, in this example 1, the brood cell of the thermophilic bacillus in rice is germinateed the 7th hour the most vigorous time period by 70 ℃ of insulations, makes combustion heater 5 actions then.Therefore, according to this example 1, if consider insulation in 18 hours, then begin to make after 5 hours (spy opens flat 9-276134 communique) meal pot in the past of heater action to compare with the breeding of thermophilic bacillus, prevented the drying of insulation rice, and, also there is not the problem of peculiar smell and flavescence to produce in the back breeding of controlling the thermophilic bacillus of auxotype in 18 hours of insulation beginning.Therefore, according to this example 1, can control the breeding of thermophilic bacillus, can be incubated for a long time with again heating times still less simultaneously.
The gas rice cooker of (example 2) this example 2, in rice cooker shown in Figure 1, utilize 12 pairs of electric heaters of muff heater control section 7 to carry out action control, make burned rice insulation at about 70 ℃, utilize simultaneously combustion heater control section 13, combustion heater 5 is moved 1 time after 6～8 hours in the insulation beginning.Again, begin approximately every 4 hours from this action of the 1st time, its action is heated for 2 times again, each so that between 1 second～5 minutes, rice maintained in 80 ℃～110 ℃ the temperature range.And other consists of with example 1 is the same.
The insulation action of combustion gas meal pot of this example 2 describes with reference to Fig. 2, Fig. 3 and Fig. 5.Fig. 2 be expression meal pot pot 2 heating has been carried out 3 minutes again the time variations in temperature, and solid line represents the variations in temperature of the rice bottom in meal pot pot 2, dotted line is represented the variations in temperature on the rice top in meal pot pot 2.It is (individual/g) variation owing to heating the viable count that makes the thermophilic bacillus again that Fig. 3 is expression.Fig. 5 is the flow chart of the control procedure after the expression insulation action beginning.
As shown in Figure 5, when the action of when beginning insulation action steps performed S201～S208, the action of the step S101～S108 of the example 1 that it is represented with Fig. 4 is identical, and in insulation beginning the last the 7th hour, combustion heater 5 is moved, carry out the 1st time heating again.
Then, after the insulation beginning, through 11 hours (S219), so that combustion heater 5 moves again, as the 2nd again heating, and the temperature of rice cooker pot 2 is risen rapidly (S220).The heat time heating time of this moment, the same in the time of with the 1st time heating again, move 3 minutes (S221).Like this, observe among Fig. 2 the 11st hour rice temperature, with through 7 hours the 1st time more the same heating the time, the rice in the rice cooker pot 2 are warmed up in 80 ℃～110 ℃ the temperature range.At this moment, observe near the 11st hour of Fig. 3 as can be known, although the slowly breeding after heating finishes again from the 1st time of the thermophilic bacillus in the rice is increased to 10 before the heating again at this 2nd time
3Near individual/g, but since again the heating reduce to again 10/below the g.This heating again of the 2nd time through the stipulated time (this example is 3 minutes) (S221), make combustion heater 5 release (S222), return common insulation action.
Then, after the insulation beginning, through 15 hours (S223), so that combustion heater 5 moves again, as the 3rd time again heating, and the temperature of rice cooker pot 2 is risen rapidly (S224).The heat time heating time of this moment, the same in the time of with the 1st time heating again, move 3 minutes (S225).Like this, with among Fig. 2 through 7 hours the 1st time again heating and through 11 hours the 2nd time more the same heating the time, the rice in the rice cooker pot 2 are warmed up in 80 ℃～110 ℃ the temperature range.Therefore, observe near the 11st hour of Fig. 3 as can be known, although the slowly breeding after heating finishes again from the 2nd time of the thermophilic bacillus in the rice was increased to 10 in the past in this again heating of the 3rd time
2Near individual/g, but since again the heating reduce to again 10/below the g.Thereby this heating again of the 3rd time process stipulated time (this example is 3 minutes) (S225) makes the release (S226) of combustion heater 5.After this,, after the release of combustion heater 5, timer is resetted (S227), turn back to the common insulation action of carrying out that utilized electric heater as the 3rd time heating again.
For after the end of cooking, being incubated 24 hours rice like this, its rice of the 24th hour is made an assessment, conclusion is not have to find to become unfavorable condition hard and sticky end occurs at rice cooker pot 2.And any point of the color of rice does not have the special place of worrying.This has proved, because the viable count of thermophilic bacillus is about 10
7Individual/as to emit peculiar smell etc. when g is above, however owing to heat action as this example 2, such as shown in the 24th hour among Fig. 3 of the viable count of thermophilic bacillus reduces to the degree of 10/g again.
As mentioned above, according to this example 2, can control the drying of the rice that causes because of heating, stop simultaneously the breeding of thermophilic bacillus, thereby can prevent the peculiar smell in the rice and flavescence takes place.Again, along with the breeding of thermophilic bacillus in the rice, about 10% of this viable count becomes brood cell's type and exists, and the thermophilic bacillus of this brood cell's type constantly germinates again and becomes auxotype.Be made as every 4 hours such as this example 2, the 2 times again time interval of heating with the 3rd time thus, than 7 hours weak points of the 1st time, breed rapidly by controlling like this thermophilic bacillus.This result is can prevent through 24 hours later taste deterioration.
Again, according to this example 2, the heating again that utilizes combustion heater 5 to carry out in the insulation, in insulation in 24 hours, 3 times altogether (after the 7th hour, after the 11st hour, after the 15th hour), with carry out every 5 hours, altogether 4 times again the method in the past (spy opens flat 9-276134) of heating compare, can prevent the dry of rice and can save 1 time heat energy again.Therefore,, can control the breeding of thermophilic bacillus, can be incubated for a long time by the number of times of heating more still less simultaneously according to this example 2.
The gas rice cooker of (example 3) this example 3, in rice cooker as shown in Figure 1, if after insulation beginning through before the again heating after the stipulated time constantly, operate long-time heat-insulation switch 17, then constantly heated again by combustion heater control section 13 in heating again, if after this heats constantly again, operate long-time heat-insulation switch 17, then heat again at once.And its other formation is identical with example 1.
The insulation action of the gas rice cooker 1 of this example 3 describes referring to figs. 1 through Fig. 3 and Fig. 6.Fig. 6 is the flow chart of the control procedure after the expression insulation action beginning.
As shown in Figure 6, when beginning when action insulation, the time that finishes cooking is stored in the memory 14 in the control device 10 (S301), then, in combustion heater control section 13, monitor, differentiate whether long-time heat-insulation switch 17 is ON (S302).When long-time heat-insulation switch is ON, differentiate whether passed through 7 hours (S303) finish time of cooking of from memory 14, storing.If also not through 7 hours, then return the supervision action of step S303, until through 7 hours, continuous alert status before this.Like this, if continue this holding state, begin simultaneously insulation, through 7 hours, perhaps operate long-time heat-insulation switch 17 at step S302 and be the time of ON, passed through 7 hours, then utilize combustion heater control section 13 to make combustion heater 5 action and the temperature of rice cooker pot 2 is risen rapidly.At this moment, this example 3, also the step S110 ~ S117 with example 1 is identical, according to the rice amount of meal pot control section 11 by the motion detection of cooking, by combustion heater control section 13 decision heat time heating time,, make combustion heater action (S310 ~ S317) according to this heat time heating time.
Then, pass through official hour (this example is 3 minutes) (S317), then make gas burner 6 stop working, finish the action (S318) of combustion heater 5 when the heating of being undertaken by combustion heater 5 again.Again, after the release of combustion heater 5, the memory contents (S328) of deletion memory 14 is returned the insulation action of being undertaken by electric heater 7.The result is, after the again heating of being undertaken by combustion heater 5 finishes, through after about 1 and a half hours, through 8 and a half hours the time, make the rice in the rice cooker pot 2 be maintained at about 70 ℃.
As implied above is at long-time heat-insulation switch 17, to be the situation of ON when beginning also not through 7 hours from insulation, if but through 7 hours, then heated by combustion heater 5 at once in this example 3 again.Thus, compare with the time period that the propagation of thermophilic bacillus in the rice is the most vigorous, again the time of heating not too late, can be at this moment between near moment of section heat again.Therefore, according to this example 3, it doesn't matter with the time of pressing long-time insulation switch 17, the brood cell's of thermophilic bacillus in rice the vigorous time period of germination, perhaps at this moment between near moment of section heat again, can increase effect thus greatly for the control of thermophilic bacillus breeding.The result is 18 hours the long-time interior rice that can both eat delicious food after the end of cooking.
The combustion gas meal of (this example 4) this example 4 pot is in meal pot as shown in Figure 1, utilize combustion heater control section 13 to carry out above-mentioned 1 time heating again after, carried out secondary every 4 hours by combustion heater 5 approximately and heat again.This be because, when considering insulation in 24 hours, even 1 time heating again, after this brood cell's type thermophilic bacillus that is also surviving is also germinateing in rapid succession, is breeding, therefore, time period is consistent therewith, heats again, and the viable count of the thermophilic bacillus that exists with auxotype in whole 24 hours is reduced.And its other formation is identical with example 1.
The insulation of the gas rice cooker of this example 4 action, with reference to from Fig. 1 to Fig. 3 and Fig. 7 describe.Fig. 7 is the flow chart of the control procedure after the expression insulation action beginning.
As shown in Figure 7, when insulation action at the beginning, carry out the action of the step S401～S418 identical with step S301～S318 in the example 3 shown in Figure 6.When if long-time insulation switch 17 is ON, begin the insulation after not through 7 hours, then standby, in through 7 hours, make combustion heater 5 actions, when being ON, begin to pass through 7 hours after the insulation as if long-time insulation switch 17 again,, then make combustion heater 5 actions at once, carry out the 1st time heating again.Here, for this example 4, in above-mentioned heating more at first, make the timer action.(S403a)。
Then, the time that monitoring is measured by timer, if the 1st time again after the heating beginning through 4 hours (S419), combustion heater 5 move again, heat again as the 2nd time, and the temperature of rice cooker pot 2 risen rapidly (S420).The heat time heating time of this moment, the same when above-mentioned the 1st time is heated again, move 3 minutes (S421).For this example 4, above-mentioned the 1st time again heating after insulation beginning, carried out in the 17th hour.Like this, this again heating of the 2nd time was carried out later in the insulation beginning on the 11st hour.The result is with the same in the situation shown in the example 2, to be increased to 10 before the heating again at the 2nd time
3Thermophilic bacillus near individual/g the rice is because heating reduces to again 10/g following (with reference to Fig. 2, Fig. 3) again.This heating again of the 2nd time process stipulated time (this example is 3 minutes) (S421) makes the release (S422) of combustion heater 5, returns common insulation action.
Then, the time that monitoring is measured by timer, if the 1st time again after the heating beginning through 8 hours (S423), combustion heater 5 move again, heat again as the 3rd time, and the temperature of rice cooker pot 2 risen rapidly (S424).The heat time heating time of this moment, the same when above-mentioned the 1st time is heated again, move 3 minutes (S425).Since above-mentioned the 1st time again heating be to carry out in later the 7th hour in the insulation beginning, therefore the 3rd time again heating be to carry out in the 15th hour after the insulation beginning.Through 7 hours the 1st time again heating and the same when heating again through constantly the 2nd time in 11 hours, the rice in the rice cooker pot 2 are warmed up in 80 ℃～110 ℃ the temperature range among this result and Fig. 2.The result is with the same in the situation shown in the example 2, to be increased in the past 10 the 3rd time again heating
2Thermophilic bacillus near individual/g the rice is because heating reduces to again 10/g following (with reference to Fig. 3) again.Then, this heating again of the 3rd time process stipulated time (this example is 3 minutes) (S425) makes the release (S426) of combustion heater 5.After this, combustion heater 5 is after the release of heating again as the 3rd time, and making timer is OFF (S427), then leaves out the memory contents (S428) of the memory 14 of storing the concluding time of cooking, turns back to the common insulation action that utilizes electric heater 7.
As mentioned above, according to this example 4, can suppress to cook finish after, from beginning insulation through the long rice drying that becomes, can stop the breeding of thermophilic bacillus, can prevent peculiar smell and rice flavescence in the rice.
Again, according to this example 4, the heating again that utilizes combustion heater 5 to carry out in the insulation, in insulation in 24 hours, 3 times altogether (after the 7th hour, after the 11st hour, after the 15th hour), with carry out every 5 hours, altogether 4 times again the method in the past (spy opens flat 9-276134) of heating compare, can prevent the dry of rice and can save 1 time heat energy again.
The gas rice cooker of (example 5) this example 5, in rice cooker as shown in Figure 1, if from the 1st time again heating constantly approximately through the 2nd time after 4 hours again before the heating constantly, operate long-time heat-insulation switch 17, then by combustion heater control section 13, the 2nd time again heating constantly carry out this and heat again, if at this 2nd time again after the heating constantly, operate long-time heat-insulation switch 17, then carry out at once the 2nd again heating.And, heated laggard mistake more about 4 hours, and carried out the 3rd time heating again for this 2nd time.And its other formation is identical with example 1.
The insulation action of combustion gas meal pot 1 of this example 5 describes referring to figs. 1 through Fig. 3 and Fig. 8.Fig. 8 is the flow chart of the control procedure after the insulation action beginning.
As shown in Figure 8, when entering the insulation action, in combustion heater control section 13, monitor from the insulation beginning whether passed through 7 hours (S501).When through 7 hours, then will heat constantly again as the 1st time this moment, be stored in the memory 14 in the control device 10 (S502), then, make combustion heater 5 actions by combustion heater control section 13, and the temperature of rice cooker pot 2 is risen rapidly.At this moment, for this example 5, also identical with step S110～S117 in the example 1, according to the control section 11 rice amount that detects in the action of cooking of cooking, determine heat time heating time by combustion heater control section 13, according to this heat time heating time, make combustion heater action (S510～S517).
Then, when being heated again by combustion heater through official hour (this example is 3 minutes) (S517), then make gas burner 6 stop working, finish the action (S518) of combustion heater 5, turn back to the common insulation action that utilizes electric heater 7.The result is, after the again heating of being undertaken by combustion heater 5 finishes, through after about 1 and a half hours, through 8 and a half hours the time, make the rice in the rice cooker pot 2 be maintained at about 70 ℃.
Then, the action of the again heating after the 2nd time is described.After above-mentioned the 1st time heating is carried out again, when pressing (S519) when making again heating carry out for several times long-time heat-insulation switch 17, differentiate the 1st time of from memory 14 storage again heating constantly whether through 4 hours (S520).If also not through 4 hours, the then supervision of repeating step S512 action, until through 4 hours, continuous alert status before this.Then, if continue this holding state, simultaneously after the 1st time the again heating through 4 hours, perhaps when operating long-time heat-insulation switch 17 for ON, passed through 4 hours step S512, then make timer action (S521), utilize combustion heater control section 13 to make combustion heater 5 actions and the temperature of rice cooker pot 2 is risen rapidly (S522).The heat time heating time of this moment, the same in the time of with above-mentioned the 1st time heating again, move 3 minutes (S523).To set for this example 5, above-mentioned the 1st time again heating be after the insulation beginning, to carry out in the 7th hour, and before after the 1st time heating is carried out again, through 4 hours, make long-time heat-insulation switch 17 be ON.Like this, this 2nd time again heating after insulation beginning, carried out in the 11st hour.The result is with the same in the situation shown in the example 2, to be increased to 10 before the heating again at the 2nd time
3Thermophilic bacillus near individual/g the rice is because heating reduces to again 10/g following (with reference to Fig. 2, Fig. 3) again.This heating again of the 2nd time process stipulated time (this example is 3 minutes) (S523) makes the release (S524) of combustion heater 5, returns common insulation action.
Then, differentiation is above-mentioned heats after the insulation beginning whether carried out (S525) 3 times again.Just, be set at, cook and finish afterwards, begin, carry out 3 heating again by combustion heater 5 from insulation for the above-mentioned form 5 of basis.At this moment, because heating was only carried out 2 times again, so turn back to (S525) before the above-mentioned steps S502.Monitor again the time of being measured by timer, if the 2nd time again after the heating beginning through 4 hours (S520), then timer is resetted and for behind the ON, again make combustion heater 5 actions 3 minutes as the 3rd again heating, make the temperature of rice cooker pot 2 rise rapidly (S522, S523).This again heating of the 3rd time because, above-mentioned the 2nd time again heating after insulation beginning, carried out in the 11st hour, carry out so it is after the insulation beginning the 15th hour.This result is, and is the same when namely heating through 11 hours the 2nd time through 7 hours the 1st time again heating and after this 4 hours among Fig. 2 again, the rice in the rice cooker pot 2 is warmed up in 80 ℃～110 ℃ the temperature range.The result is with the same in the situation shown in the example 2, to be increased in the past 10 the 3rd time again heating
2Thermophilic bacillus near individual/g the rice is because heating reduces to again 10/g following (with reference to Fig. 3) again.Then, this heating again of the 3rd time process stipulated time (this example is 3 minutes) (S523) makes the release (S524) of combustion heater 5.
After this, after this 3rd time heating is carried out again (S525), with above-mentioned the 1st time again heating constantly, from memory 14, remove (S526), turn back to the common insulation action that utilizes electric heater 7.
For this example 5, the interval between the 24th hour is constantly played in the 3rd heating of last heating again, greater than 4 hours the time interval of the 2nd time and the 3rd time.But, owing to utilize above-mentioned the 3rd heating again, the number of the whole thermophilic bacillus in the rice is reduced significantly, therefore as shown in Figure 3, even at the 24th hour, the number of thermophilic bacillus also 10/below the g, breeding is less than the degree of emitting peculiar smell.
As mentioned above, according to this example 5, even after after beginning insulation, once having heated again by heater, long-time heat insulation function is set again, also can suppress the breeding of the thermophilic bacillus in the rice in this case effectively, this result is to have spent 24 hours after the end of cooking, also edible rice to delicious food.Just, in rice along with the breeding of thermophilic bacillus, 10% of its viable count becomes brood cell's type and exists, after heating again for 1 time, because the bacillus of these brood cell's types constantly germinates, becomes after the time period of auxotype was about 4 hours, therefore making the time interval of the heating again of the 2nd time and the 3rd time is every 4 hours, can suppress the thermophilic bacillus like this and breed rapidly.Again, shown in this example 5, be that long-time heat-insulation switch 17 is after the 1st time again heating, also less than just not being the situation of ON through 4 hours, if but through 4 hours, then heated by combustion heater 5 at once again.Thus, compare with the time period that the breeding of thermophilic bacillus in the rice is the most vigorous, again the time of heating not too late, and between can be at this moment near the moment of section heat again.
According to the combustion heater 5 shown in described above the example 1～5, with respect to electrical heating, as the characteristic of gas heating, owing to be the firepower that utilizes combustion gas, therefore in the short time, can rise to the temperature of setting.For example, by 3 minutes heating, rice that the most easily be heated, meal pot pot inner bottom part is warmed up to about 100 ℃, unwarmed rice top is warmed up to 85 ℃ (with reference to Fig. 2).Therefore can suppress, cause the breeding of the thermophilic bacillus of peculiar smell in the rice and flavescence.Like this, can carry out necessary heating killing the thermophilic bacillus, and don't increase too much heat in order to avoid make the rice drying.
Again, combustion heater 5 has been used in above-mentioned again heating, but also can use electric heater to heat usefulness as this again.This situation, can with electric heater 7 dual-purposes that usually are incubated, perhaps can equip other dedicated electric heater.And, be not only applicable to the such combustion gas meal pot of present embodiment, also be applicable to electric cooker.Like this, for this electric cooker, also the electric heater of cooking and the electric heater dual-purpose that usually is incubated can be used for above-mentioned again heating, again, the more special-purpose electric heater of heating can be installed in addition also.For electrically heated situation, compare with combustion gas heating, programming rate and rice heat transfer aspect had deficiency slightly, but also can fully suppress the breeding of the thermophilic bacillus in the rice.
Again,,, used electric heater 7, but also can use other thermals source such as halogen tungsten lamp as muff heater at this example 1～5.
Again, for this example 1～5, as the again heat time heating time of utilizing combustion heater 5, be set at 1 minute, 2 minutes or 3 minutes, but also can between 1 second to 5 minutes, suitably determine.Rear 7 hours of insulation beginning so that combustion heater 5 actions still also can the scope after 6～8 hours suitably determine again.
Again, for this example 1～5, as described above, stipulated heat time heating time again, but the situation that also has the difference because of the rice amount that bottom rice Jiao of meal pot pot 2 is fallen, therefore, reaching design temperature (the flame-out temperature of cooking in heat time heating time again, or than the flame-out lower temperature of cooking, for example 110 ℃) situation under, as long as pay the utmost attention to design temperature, and make the heating release.
Again, above-mentioned is that the rice amount can be divided into large, medium and small 3 grades, select the heat time heating time of heater 5 and control, but, according to the capacity of the capacity of meal pot, rice amount, combustion heater etc., also can more segment shelves, perhaps also can be divided into rice and have a good appetite with little 2 grades, this according to circumstances can suitably determine.
Also can control so again, namely having more than is the heat time heating time of selecting as described above heater 5 according to the rice amount, but when the rice temperature of rice cooker pot 2 interior bottoms reaches 110 ℃, makes heater 5 releases.This be because, when reaching 110 ℃, estimate that the temperature on rice top has also reached more than 80 ℃ as the rice temperature of bottom, as the temperature of rice in meal pot pot 2, be controlled on the whole among 80～110 ℃ the scope.
Again, for example 2,4,5, be set the 2nd time, the 3rd time again heat time heating time with the 1st time again heat time heating time identical, but also can control like this, maximum temperature when soon heating again for the 1st time in meal pot pot 2 temporarily is stored in the memories that wait in the control device 10, when reaching the maximum temperature of this temporary transient storage, make the 2nd time, the 3rd time heating end again.
