First, general description forms each operation of the operation of cooking.
As shown in Figure 3, Figure 4, the operation of cooking of the cooker of present embodiment 1 consists of preheating procedure (the step S1 of Fig. 4), heating process (the step S2 of Fig. 4), strong firer's order (the step S5 of Fig. 4), weak firer's order (the step S6 of Fig. 4), drying process (the step S7 of Fig. 4) and steaming process (the step S8 of Fig. 4).In addition, heating process consists of the front operation that heats up (the step S3 of Fig. 4) and the rear operation (the step S4 of Fig. 4) that heats up.In addition, before heating up, operation is equivalent to the first operation of the present invention, and after heating up, operation is equivalent to the second operation of the present invention.
So-called preheating procedure, is the stage before the water boiling in pot shape container 5, with set point of temperature heating kettle shape 5 stipulated times of container, promotes thus the water suction of rice, generates as the sugar of sweet ingredient with as the operation of the taste component of the amino acid of delicious composition etc.In preheating procedure, control assembly 8 repeatedly to the blocking of the energising of heater coil 3 and electric power carry out temperature adjustment so that the temperature of pot shape container 5 becomes the preheat temperature T of regulation.Here, preheat temperature T is that the gelatinization that the temperature of the water in pot shape container 5 can be maintained to rice does not start the temperature (being for example less than about 60 ℃) of the temperature of degree.
So-called heating process is from preheating procedure finishes until the operation of the water boiling in pot shape container 5.By operation before heating up with after heating up, operation forms heating process.
Before intensification in operation, the water suction of rice promptly makes progress and starts gelatinization, therefore, by the rice in pot shape container 5, is not absorbed and the amount of residual water (being called residual water) little by little reduces.If the temperature distributing disproportionation of the inside of pot shape container 5 is even, water suction state becomes inhomogeneous, produces hard place and soft place when cooking, becomes cooking inequality.In order to cook palatably, the temperature inequality that reduces pot shape container 5 inside in heating process is important, therefore, need to before intensification, in operation, based on heating, produce the convection current of water.For what realize operation before such intensification, add thermal control aftermentioned.
In addition, after intensification, in operation, the water suction of rice further makes progress, and the amount of residual water further reduces than operation before heating up.Now, if rice is come on the water surface, be not immersed in the cooking meeting hardening of the rice of the part in water, therefore, after this heats up, in operation, it is important that rice remains the state being immersed in residual water.For what realize operation after such intensification, add thermal control aftermentioned.
If the water boiling in pot shape container 5, enters strong firer's order.In this strong firer's order, by with the regulation electric power heating stipulated time, maintain boiling so that the temperature in pot shape container 5 becomes the set point of temperature that the thing of cooking can seethe with excitement more than the boiling temperature maintaining, residual water spreads all over equably in pot shape container 5.
In weak firer's order, residual water becomes the state being absorbed by rice hardly, and by under this state, boiling temperature being kept to the stipulated time, the gelatinization of the starch of rice is promoted.
So-called drying process, refers to for blowing away the operation of remaining moisture.If arrive, judge there is no remaining water in pot shape container 5, become the temperature (dry judgement temperature) of the situation of drying regime, travel to steaming process.In steaming process, the end of cooking when through the stipulated time.
Then,, according to Fig. 4, further illustrate the action of cooking of the cooker of present embodiment 1.
First, user will put into the rice of ormal weight and be received into the jar 2 of body 1 with the pot shape container 5 of the water of this meter of corresponding water yield of amount, close enclosing cover 10a, the cooking switch 39 of push/display part 13 and while cooking the action indication starting, the operation of cooking starts.
Opened the switch 39 of cooking by user, to cook while starting to be instructed to, control assembly 8 enters preheating procedure.
Fig. 5 is illustrated in the pot shape container 5 of preheating procedure zero hour and as being cooked the rice of thing and the schematic cross-section of water.At this constantly, with respect to the R above of the rice of the bottom surface approximate horizontal of pot shape container 5, apart from water surface W, leave distance A, become that rice is whole is immersed in the state in water.
In the preheating procedure of step S1, control assembly 8 starts the metering in the elapsed time of preheating by time measurement parts 7, repeatedly with regulation electric power P1, the energising of heater coil 3 and electric power are interdicted to the temperature adjusting (with reference to Fig. 3) of carrying out pot shape container 5, the detected temperatures of cooking bottom temperature sensor 4 is maintained to the preheat temperature T of regulation.Then, when the elapsed time being metered into by time measurement parts 7 reaches the preheating time of regulation, control assembly 8 enters the heating process of step S2.
Pot shape container when here, Fig. 6 is illustrated in preheating procedure and finishes and as being cooked the rice of thing and the schematic cross-section of water.At this constantly, the R above with respect to the rice of the bottom surface approximate horizontal of pot shape container 5, leaves apart from 0.45A~0.65A apart from water surface W, becomes that rice is whole is immersed in the state in water, but distance shortens than the preheating procedure zero hour (with reference to Fig. 5).
In the heating process of step S2, first, operation before the intensification of execution step S3.
Before intensification, in operation, control assembly 8 is with current on time A/(A+B) heater coil 3 is passed into regulation electric power P2(S31).Here, A is to the conduction time of heater coil 3 (time of the higher calorific power of operation before heating up), and B is the energising dwell time (time of the low thermal power of operation before heating up) stopping the energising of heater coil 3.That is, control assembly 8 is by repeatedly energising and the energising of the regulation electric power P2 of heater coil 3 being stopped, with alternately repeatedly the heating mode of higher calorific power state and low-heat power rating (front operation pattern) heat.In order to cause the convection current of water in pot shape container 5 by heating, becoming more long "on" position (higher calorific power state) afterwards, the heating mode that the halted state of switching on more for a long time (low-heat power rating) is set is good.In present embodiment 1, A=40 second for example, B=20 second, by energising in 40 seconds repeatedly, within latter 20 seconds, stop such intermittent running, promote the convection current in pot shape container 5.In addition, also can substitute by stopping that the energising of heater coil 3 is realized to low thermal power, by electric power little when than higher calorific power, to heater coil, 3 energisings realize low thermal power.
Before intensification, in operation, control assembly 8 is judged the detected temperatures T of internal temperature sensor 14 0whether be the threshold value T of regulation 1above, at the detected temperatures T that judges internal temperature sensor 14 0threshold value T 1(S32 in situation above; Be), enter operation after the intensification of step S4.In this step S32, the detected temperatures T based on internal temperature sensor 14 0, judge the quantity of residual in pot shape container 5.
The judgement of the quantity of residual of the detected temperatures based on internal temperature sensor 14 is the principle of having utilized quantity of residual to infer according to the water suction state of rice.Generally speaking, the water suction of rice is determined by the relation of the temperature and time of the operation of cooking.Therefore, in advance by experiment etc., investigation is with current on time A/(A+B) temperature of heating object (meter He Shui) in pot shape container 5 when heater coil 3 is passed into regulation electric power P2 and the relation of quantity of residual, using become regulation quantity of residual time internal temperature sensor 14 temperature that detects as threshold value T 1and it is pre-stored in not shown storage device.Then, by contrast, be stored in the threshold value T in not shown storage device 1detected temperatures T with internal temperature sensor 14 0, judge the quantity of residual in pot shape container 5.
Fig. 7 means the pot shape container of before intensification operation finish time and as the rice of heating object and the schematic cross-section of water.At this constantly, the R above with respect to the rice of the bottom surface approximate horizontal of pot shape container 5, leaves apart from 0.3A~0.4A apart from water surface W, and being that rice is whole is immersed in the state in water, but further reduces the distance than the preheating procedure finish time (with reference to Fig. 6).In addition, the rice before also sometimes cooking according to user's setting and the situation (for example situation of larger inclination that is configured to above of rice) of water, the grain of rice of a part is exposed on the water surface.
Be for example as shown in Figure 7, rice is whole is immersed in the state in water, but becoming the quantity of residual of comparing the state that the R above of rice and the distance of water surface W further shorten the finish time with preheating procedure is the quantity of residual of regulation, and the temperature now being detected by internal temperature sensor 14 becomes threshold value T 1.
Known according to experiment, operation after for example, heating up if travel under the state of the quantity of residual when the temperature of heating object (meter He Shui) becomes 70 ℃ (state as Fig. 7 illustration), can suppress cooking inequality.Therefore, in present embodiment 1, if the temperature of heating object (meter He Shui) becomes more than 70 ℃, judge that quantity of residual reduces to below ormal weight, the rear operation that heats up of dividing a word with a hyphen at the end of a line to.In addition, in present embodiment 1, by the detected temperatures of internal temperature sensor 14, detect the temperature of heating object (meter He Shui), when the temperature of heating object (meter He Shui) is 70 ℃, the detected temperatures of internal temperature sensor 14 shows 60 ℃, therefore, and with the threshold value T stipulating 1as 60 ℃.
After the intensification of step S4 operation be the detection information of control assembly 8 based on internal temperature sensor 14 until detect boiling in pot shape container 5 during operation.When entering the rear operation of intensification, control assembly 8 is with current on time C/(C+D) heater coil 3 is passed into regulation electric power P3(S41).Here, C is to the conduction time of heater coil 3 (time of the higher calorific power of operation after heating up), and D is the energising dwell time (time of the low thermal power of operation after heating up) stopping the energising of heater coil 3.That is, control assembly 8 is by repeatedly energising and the energising of the regulation electric power P3 of heater coil 3 being stopped, and with the heating mode (rear operation pattern) of alternate repetition higher calorific power state and low-heat power rating, heats.
Here, energising dwell time D is than the short time (D < B) of energising dwell time B in operation before heating up.In the situation that the state that residual water tails off, during to the state (higher calorific power state) of heater coil 3 energising, residual water is boiled to a pot top for shape container 5, rice integral body in pot shape container 5 is immersed in residual water, but when energising halted state (low-heat power rating), the water surface of residual water declines, and residual water accumulates in a pot bottom for shape container 5.If the water surface of residual water declines, it is longer that residual water accumulates in pot state continuance of the bottom of shape container 5, even to the energising halted state of heater coil 3, continue longer, the meter Cheng Wei on pot shape container 5 tops is positioned at the state on the water surface, cannot absorb water and more dry, produce water suction state poor of the rice on bottom in pot shape container 5 and top.That is, if longer to the energising halted state of heater coil 3, on bottom and the top of pot shape container 5, produce water suction inequality, can become the reason of cooking inequality.Therefore, have enough residual water during (heat up before operation), as described above in order further to promote convection current, the thermal control that adds as " becoming long time "on" position (higher calorific power state) afterwards; the heating mode of long time energising halted state (low-heat power rating) is set ", after the intensification tailing off in residual water in operation, carry out with heat up before operation compare the time that shortens low thermal power heating mode add thermal control.So, can before intensification, operation in operation, suppress cooking inequality afterwards with heating up.In addition, in present embodiment 1, C conduction time after heating up in operation was made as than the short time of A conduction time in operation before heating up, but was not limited to this.
And, if the detected temperatures of control assembly 8 based on internal temperature sensor 14 detects the situation (S42) that the heating object in pot shape container 5 seethes with excitement, enter strong firer's order (S5).
In strong firer's order of step S5,8 pairs of heater coils 3 of control assembly pass into regulation electric power P4, until the process of the stipulated time in the strong firer's order of time measurement parts 7 metering.By maintaining fluidized state with the regulation electric power heating stipulated time, residual water spreads all over more equably in pot shape container 5.
When finishing, strong firer's order of step S5 travels to weak firer's order of step S6.In order to make a meter gelatinization, need to be by 98 ℃ of above maintenances 20 minutes.Therefore,, in weak firer's order of step S6, control assembly 8 makes time measurement parts 7 start the metering in elapsed time, is not burnt such regulation electric power P5 carry out the intermittently power-on to heater coil 3 with the meter He Shui in pot shape container 5.And when the elapsed time being metered into by time measurement parts 7 reaches the stipulated time, control assembly 8 enters the drying process of step S7.
The drying process of step S7 from weak firer's order finishes until pot shape container 5 arrives the dry operation of judging during temperature.The detection information of control assembly 8 based on cooking bottom temperature sensor 4, detects pot shape container 5 and whether arrives the dry temperature of judging.In drying process, control assembly 8 carries out the intermittently power-on to heater coil 3 with regulation electric power P6, makes the electric power amount of unit interval increase than weak firer's order.When the detected temperatures of control assembly 8 based on cooking bottom temperature sensor 4 detects the dry judgement temperature of the heating object arrival regulation in pot shape container 5, enter the steaming process of step S8.
In the steaming process of step S8, control assembly 8 makes time measurement parts 7 start the metering in elapsed time, when the elapsed time being metered into by time measurement parts 7 reaches the stipulated time, finishes to cook operation.
As mentioned above, in present embodiment 1, before intensification, operation and the rear operation that heats up are switched powered-on mode.And, before the relatively many intensifications of quantity of residual in operation, with the heating mode of higher calorific power and low thermal power repeatedly, heat.Therefore, in pot shape container 5, the generation of the convection current of heating object can be promoted, cooking inequality can be suppressed.In addition, when residual water reduces to ormal weight, be made as from heat up before the different powered-on mode of operation, with the low thermal power of repeatedly short than the time of the low thermal power in operation before heating up time and the heating mode of higher calorific power, heat.Therefore, can be suppressed at less residual water in the rear operation that heats up and accumulate in the part in pot shape container 5, can make residual water spread all over more equably in pot shape container 5.In addition, after intensification, in operation, even ratio heats up, front operation, than the short time, by the intermittently power-on of repeatedly switching on and switching on and stopping, also can promoting the convection current of the heating object in pot shape container 5.Thereby the temperature that can suppress heating object is uneven, can provide the delicious rice that cooking is uneven few to user.
In addition,, in present embodiment 1, from heating up, operation is divided a word with a hyphen at the end of a line to operation after heating up, and as the determinating reference that switches powered-on mode, uses quantity of residual, as for judging the formation of this quantity of residual, uses the detected temperatures of internal temperature sensor 14.By using internal temperature sensor 14, can directly not infer contiguously quantity of residual with rice, be health.
In addition, by rice and the temperature of water based on as heating object, infer quantity of residual, can judge accurately the opportunity of dividing a word with a hyphen at the end of a line to operation after intensification.
In addition, in present embodiment 1, in the detected temperatures of internal temperature sensor 14, are setting T 1when more than=60 ℃, being judged to be quantity of residual becomes below ormal weight, but also can be without internal temperature sensor 14 with cooking bottom temperature sensor 4 or the pot side temperature sensor (not shown) that detects the temperature of pot side, detect the temperature of heating object, based on this, judge quantity of residual.In this case, as long as the temperature of the pot bottom of control assembly 8 when the temperature of rice and water becomes 70 ℃ or pot side surface part is pre-stored as the threshold value of regulation as mentioned above, the detected temperatures of judging cooking bottom temperature sensor 4 or pot side temperature sensor be the threshold value of this regulation divide a word with a hyphen at the end of a line to when above heat up after operation.In addition, also can use the direct sensor of measuring the temperature of rice or water, in this case by the threshold value T of regulation 1be made as 70 ℃.
Embodiment 2
In present embodiment 2, represent the example as quantity of residual judging part by time measurement parts.In addition, in present embodiment 2, centered by the difference with embodiment 1, describe, the identical or suitable structure of Fig. 1~Fig. 4 with above-mentioned is marked to identical Reference numeral.

First, the aggregate value of the energising electric power of the heater coil 3a shown in Figure 11 (c) and heater coil 3b is described.As shown in Figure 11 (c), after intensification in operation to heater coil 3a or heater coil 3b energising conduction time C2 and the heating mode that stops the energising dwell time D2 alternate repetition of energising heat.And, after heating up, this, in operation, makes to stop the energising dwell time of the energising of heater coil 3a and heater coil 3b (time of the low thermal power of operation after heating up) D2 the short time (D2 < B) of time B that is the low thermal power than in operation before heating up.That is, with embodiment 1 in the same manner so that low thermal power and the higher calorific power heating mode repeatedly of the time shorter than the time of the low thermal power in operation before heating up heat.Therefore, with embodiment 1 in the same manner, can be suppressed at heat up after in operation less residual water accumulate in the part in pot shape container 5, can make residual water spread all over more equably in pot shape container 5.
Then, illustrate respectively to being positioned at the heater coil 3a and the energising electric power that is positioned at the heater coil 3b in outside of pot inner side of shape container 5.As shown in Figure 11 (a) shows, 8 couples of heater coil 3a of control assembly are by stopping the control of switching on of the such powered-on mode of D2a conduction time after conduction time C2a.In addition,, as shown in Figure 11 (b), 8 couples of heater coil 3b of control assembly are by stopping the control of switching on of the such powered-on mode of D2b conduction time after conduction time C2b.And, with to heater coil 3a C2a conduction time, follow the mode to heater coil 3b C2b conduction time, control to the energising of heater coil 3a and heater coil 3b constantly.Like this, after intensification in operation, by any in heater coil 3a and heater coil 3b switched on selectively, realize the higher calorific power of operation after the high temperature shown in Figure 11 (c).The heater coil 3b that is positioned at the heater coil 3a of center side and is positioned at outside is switched on by the moment different, can promote convection current in the inner side of pot shape container 5 and outside.Therefore, compare with the situation that is provided with 1 heater coil 3 as embodiment 1, can also promote the convection current of the heating object in pot shape container 5.Thereby the temperature that can suppress heating object is uneven, provides to user the delicious rice that cooking is uneven few.
In addition, in Figure 11, be illustrated in the example of only heater coil 3a being switched in the front operation that heats up, but also can be with the rear operation that heats up in the same manner to heater coil 3a and heater coil 3b alternate energisation.As long as the aggregate value of the energising electric power of heater coil 3a and heater coil 3b is become to the control of switching on like that of the state shown in Figure 11 (c), can the distribution of suitable setting to the energising of heater coil 3a and heater coil 3b.

To the control of the energising electric power of heater coil 3a, 3b, can similarly carry out with Figure 11, Figure 12 shown in embodiment 4.Like this, after intensification in operation, both sides for the side surface part by the bottom from pot shape container 5 and pot shape container 5 heat, and can promote inner side in pot shape container 5 and the convection current in outside.Therefore, compare with the situation that 1 heater coil 3 is set as embodiment 1, can further promote the convection current of the heating object in pot shape container 5.Thereby the temperature inequality of heating object is suppressed, can provide the delicious rice that cooking is uneven few to user.
In addition, in embodiment 4,5, the mode of when the low thermal power of operation after intensification is described, heater coil 3a, 3b all not being switched on.But, also can be same with the mode shown in embodiment 3, during with the low thermal power of operation after heating up to the aggregate value of the energising electric power of heater coil 3a, 3b little mode during than the higher calorific power of operation after heating up, to either one or both energising in heater coil 3a, 3b.Even if so also can access same effect.
In addition, in embodiment 4,5, the example that 2 heater coils are set has been described, but 3 above heater coils also can be set.For example, also 3 heater coils of different-diameter can be and roughly be located to concentric circles pot bottom surface of shape container 5 and as triple rings structure.In addition, the heater coil of double ring structure such shown in embodiment 4 for example also can be set in the bottom surface of pot shape container 5, and in position in opposite directions, the side with pot shape container 5, heater coil be set.Even in the situation that heater coil is set more than 3 in this wise, also can compare with the time of the low thermal power with the front operation that heats up the short mode of time of the low thermal power of the rear operation that heats up, by drive selectively in a plurality of heater coils more than 1, can access same effect.
In addition, in embodiment 1~5, represented to have used as heater block the example of heater coil, but also can replace heater coil and use the electric heaters such as sheath heater.In this case, in the mode of the relatively large state of the caloric value of alternate repetition electric heater (higher calorific power state) and little state (low-heat power rating), before intensification operation and heat up after by operation, add thermal control.
In addition, detected temperatures based on internal temperature sensor 14 in embodiment 1 is judged quantity of residual, elapsed time based on 7 meterings of time measurement parts in embodiment 2 is judged quantity of residual, but the level sensor that detects the water level in pot shape container 5 also can be set, based on water level, judge quantity of residual.For example as level sensor, use with the way of contact and measure in the situation of sensor of water level, by detecting from the distance of bottom surface R to rice above of pot shape container 5 with to the distance of water surface W, can be from the difference judgement quantity of residual of these 2 distances.By directly measuring water level with level sensor, can make the kind of rice and freshness etc. on the impact of the water absorption character of rice less, precision highland judges quantity of residual, even can suppress more reliably the generation of cooking inequality.
