Then, in step S3, control part 31 drives stirring motor 4 to make stirring vane 5 with certain rotating speed (400rpm in this example) rotation, and now, the motor current test section 36 shown in Fig. 3 detects and flows through the electric current that stirs motor 4.When the electric current detecting is that 0.25A performs step S4 when following, when surpassing 0.25A, the described electric current detecting performs step S9.In step S9, judge that electric current that motor current test section 36 detects whether below 0.3A, when the electric current detecting described in judgement performs step S10 when 0.3A is following, performs step S15 when the electric current detecting described in judgement surpasses 0.3A.In step S15, whether the electric current detecting described in judgement is below 0.35A, when the electric current detecting described in judgement is that 0.35A performs step S16 when following, when the electric current detecting described in judgement performs step S21 during over 0.35A.In step S21, make display part 33 (as shown in Figure 3) show the information that expression overloads, and stop washing the running of meter pattern.In addition, step S3, step S9 and step S15 form rice amount detection running portion.
In described step S3, step S9 and step S15, after the load that stirs motor 4 detects and finishes, to inner bag 2 dress water.That is, according to the Fig. 4 as an example, the electric current detecting in step S3 is 0.25A when following, and the rice amount in inner bag 2 is below 200 milliliters.Now, control part 31 makes to show that the rice amount in inner bag 2 is below 200 milliliters on display part 33.When user sees described demonstration, for example can be to inner bag 2 dress water to level scale 41b, this level scale 41b mint-mark represents the corresponding water yield of rice of 100 milliliters-300 milliliters at the medial surface of inner bag 2.In addition, by control part 31, carry out and make to stir step S5 or the step S6 below that the rotating speed of motor 4 is 350rpm.
In addition, the electric current detecting in step S9 is 0.3A when following, and according to the Fig. 4 as an example, but the rice amount in inner bag 2 is to surpass 200 milliliters 400 milliliters of following situations.Now, control part 31 makes to show that the rice amount in inner bag 2 surpasses 200 milliliters still below 400 milliliters on display part 33.When user sees described demonstration, for example can be to inner bag 2 dress water to level scale 41a, this level scale 41a mint-mark represents the corresponding water yield of rice of 400 milliliters-550 milliliters at the medial surface of inner bag 2.In addition, now carry out and make to stir step S11 or the step S12 below that the rotating speed of motor 4 is 450rpm.
In addition, the electric current detecting in step S15 is during less than 0.35A, according to the Fig. 4 as an example, the rice amount in inner bag 2 be surpass 400 milliliters but in the situation below 550 milliliters.Now, control part 31 makes to show that the rice amount in inner bag 2 surpasses 400 milliliters still below 550 milliliters on display part 33.When user sees described demonstration, for example can be to inner bag 2 dress water to level scale 41a, this level scale 41a mint-mark represents the corresponding water yield of rice of 400 milliliters-550 milliliters at the medial surface of inner bag 2.In addition, now carry out and make to stir step S17 or the step S18 below that the rotating speed of motor 4 is 550rpm.
As mentioned above, after detecting, the load of the stirring motor 4 in described step S3, step S9 and step S15 fills water to inner bag 2, carry out step S4, step S10 and step S16 below, the temperature of the water of dress in temperature sensor 10 detection inner bags 2.Temperature sensor 10 detects the temperature of the water in inner bag 2 indirectly by detecting the temperature of inner bag 2.Afterwards in step S4, step S10 and step S16, whether the temperature that judges the water that temperature sensor 10 detects reaches 23 ℃, if judgement does not reach 23 ℃, perform step S5, step S11 and step S17, if judgement reaches 23 ℃, perform step S6, step S12 and step S18.In addition, 23 ℃ of described temperature are examples of judgment standard.
In step S5, stir motor 4 and drive 60 seconds with rotating speed 350rpm, the rice 11 in inner bag 2 is washed to rice.In addition, in step S6, stir motor 4 and drive 30 seconds with rotating speed 350rpm, the rice 11 in inner bag 2 is washed to rice.In addition, in step S11, stir motor 4 and drive 60 seconds with rotating speed 450rpm, the rice 11 in inner bag 2 is washed to rice.In addition, in step S12, stir motor 4 and drive 30 seconds with rotating speed 450rpm, the rice 11 in inner bag 2 is washed to rice.In addition, in step S17, stir motor 4 and drive 60 seconds with rotating speed 550rpm, the rice 11 in inner bag 2 is washed to rice.In addition, in step S18, stir motor 4 and drive 30 seconds with rotating speed 550rpm, the rice 11 in inner bag 2 is washed to rice.
As mentioned above, according to the temperature of the water in inner bag 2 high and low (for example, 23 ℃ above, less than 23 ℃) control short, long (for example 30 seconds, 60 seconds) of the driving time that stirs motor 4, therefore can set the washing a meter time of water temperature that is suitable for washing rice, carry out the appropriate rice of washing.
In addition according to the value of the detection electric current of the expression rice amount that detects of load in step S3, for example, when detecting the rotating speed that makes to stir motor 4 when electric current is the fewer rice amount (below 200 milliliters) below 0.25A, be 350rpm (step S5, S6).In addition in step S9, but for example, be 450rpm (step S11, S12) when detecting electric current and make when surpassing moderate rice amount below 0.25A 0.3A (but surpass 200 milliliters below 400 milliliters) to stir the rotating speed of motor 4.In addition, in step S15, when to detect electric current be more than 0.3A but for example, be 550rpm (step S17, S18) less than many rice amounts of 0.35A make to stir motor 4 rotating speed when (surpassing 400 milliliters still below 550 milliliters).As mentioned above, in washing meter Yun Zhuan, the amount of the rice 11 in inner bag 2 is more, controls stirring motor 4 and makes its rotating speed higher, therefore can set a rotating speed for the stirring vane 5 that is suitable for rice amount, carries out the appropriate rice of washing.In addition, the rotating speed that stirs motor 4 can utilize such as controls such as negative circuits.
And, in described step S5, S6, S11, S12, S17, S18, after the driving time described in driving stirring motor 4, stop driving stirring motor 4 (step S7, S13, S19) respectively.
Afterwards, in step S8, S14, S20, notify user to wash a meter operation and finish.This washes the end notification of meter operation, can be by showing or undertaken by being arranged on the warning tone of the notice sound source (not shown) in shell 19 with the common display part 33 (as shown in Figure 3) arranging of guidance panel 32 being upper.
Next, Fig. 6 represents only to put into rice in inner bag 2 and stirs motor 4 while rotating with 400rpm, the experimental result of the relation that flows through the rice amount (* 100 milliliters) that stirs the current value (A) of motor 4 and put into inner bag 2 that the motor current test section 36 drawing detects.As shown in Figure 6, rice amount in the current value that motor current test section 36 detects and inner bag 2 is proportional and increase with the increase of rice amount.Hence one can see that, by motor current test section 36, can accurately detect the rice amount in inner bag 2.Next, Fig. 7 represents to put into meter He Shui in inner bag 2 and stirs motor 4 while rotating with 400rpm, the experimental result of the relation that flows through the rice amount (* 100 milliliters) that stirs the current value (A) of motor 4 and put into inner bag 2 that the motor current test section 36 drawing detects.At this, the water yield of putting into inner bag 2 is to set according to the level scale portion of washing meter use of mint-mark on the inner peripheral surface of example inner bag 2 as shown in Figure 2 41.As shown in Figure 7, even if not only put into rice also put into water in the situation that in inner bag 2, the current value that also can detect by motor current test section 36 accurately detects the rice amount in inner bag 2.
In addition, in above-mentioned experiment, for detection of the rotational time of the stirring vane 5 of rice amount, be about 10 seconds.This 10 seconds is the shortest time that motor current test section 36 can detect rice amount.In inner bag 2, only put under the state of rice, make the long-time rotation of stirring vane 5 that grain of rice breakage may occur, and in inner bag 2, put under the state of meter He Shui, make the long-time rotation of stirring vane 5 may make nutrition leak.
Next, in the form shown in Fig. 8, one hurdle, the left side represents the current value that motor current test section 36 detects, a middle hurdle represent according to described in rice amount in the inner bag 2 that is detected of the current value that is detected.And one hurdle, the form of Fig. 8 the right represents when a stirring vane 5 for the rice amount that is detected described in correspondence rotates in inner bag 2 to make all rice become dynamic minimum speed in inner bag.Rice amount in inner bag 2 is more, makes the dynamic minimum speed of all meter Bian Cheng just higher.Therefore, while washing meter, with the increase of the rice amount in inner bag 2, and increase the rotating speed that stirs motor 4, even if the rice amount thus in inner bag 2 is many, also can make by the rotation of stirring vane 5 all meter Bian Cheng in inner bag 2 dynamic.Therefore can avoid, because of the location difference of rice 11 in inner bag 2, uneven phenomenon occurs to clean.In addition,, by being to make rotating speed minimum in the dynamic rotating speed of all meter Bian Cheng (one hurdle, the right in the form of Fig. 8) by the speed setting that stirs motor 4, can avoid unnecessary mechanical force on rice.Thus, can prevent that the grain of rice is damaged.In addition, also can roughly eliminate while washing meter water that the stirring vane 5 by High Rotation Speed the causes trouble around of dispersing towards periphery and make dirty.
, the water temperature when washing meter, the nutritional amt being retained on rice can change.That is water temperature while, washing meter is low washes that rice after rice is upper easily retains nutrition.On the other hand, in more than approximately 23 ℃ water temperatures, the not very large difference of the attrition status of nutrition.Fig. 9 represents the situation of change of the retention rate of the nutrition of reservation on water temperature when the washing meter rice after washing rice.Characteristic curve K1, the K2 of Fig. 9, K3 represent respectively, washing rice amount be 100 milliliters, 300 milliliters, 550 milliliters in the situation that, the relation of the water temperature of the nutrition reservation amount of rice when washing meter.Rice amount when washing meter is that 100 milliliters (characteristic curve K1), 300 milliliters (characteristic curve K2), 550 milliliters (characteristic curve K3) are identical, and when 23 ℃ of 7 ℃ of water temperatures and water temperatures, the retention rate of nutrition differs nearly 10%.That is, easily reservation nutrition after washing rice during than 23 ℃ of water temperatures during 7 ℃ of water temperatures.In addition, when 100 milliliters (characteristic curve K1), 300 milliliters (characteristic curve K2), 23 ℃ of water temperatures, to the retention rate of nutrition between 38 ℃ of water temperatures is roughly the same, obviously do not decline.But, when 550 milliliters (characteristic curve K3), on a declining curve to the retention rate of nutrition between 38 ℃ of water temperatures 23 ℃ of water temperatures.
Therefore, washing meter Yun Zhuan portion 37 can wash as follows meter Yun Zhuan and control: the rotational time that the time that for example, makes stirring vane 5 rotations when the water temperature detecting when temperature sensor 10 is washed during less than 23 ℃ meter is standard, and when water temperature be to make the rotational time of stirring vane 5 than the rotational time shortening of standard when more than 23 ℃.As an example, as the flowchart text with reference to Fig. 5 A, Fig. 5 B, the rotational time of standard is set as to 60 seconds, the water temperature detecting when temperature sensor 10 during less than 23 ℃ the rotational time of stirring vane 5 be set as 60 seconds, when water temperature that temperature sensor 10 detects is that the rotational time of stirring vane 5 is set as 30 seconds when more than 23 ℃.Thus, high and low (23 ℃ above, less than 23 ℃) of the water temperature when washing meter control short, long (30 seconds, 60 seconds) of the rotational time (stirring the driving time of motor 4) of stirring vane 5.By the control to described rotational time, while washing meter, can not remove too much the surface of rice, even if the rice of water temperature after 23 ℃ also can make to wash rice above retains and equal nutritional amt during 7 ℃ of water temperatures.In addition, in the present embodiment, while controlling the rotational time of the stirring vane 5 while washing meter Yun Zhuan, with water temperature 23℃Wei circle, judge the height of water temperature, but be certainly not limited only to 23 ℃ as the border of judgement water temperature.That is, also can the water temperature when washing meter set the rotational time of stirring vane 5 for a plurality of patterns.For example also can control as follows: when water temperature is more than 23 ℃, the rotational time of stirring vane 5 is set as 20 seconds; When water temperature during more than 15 ℃ but less than 23 ℃ the rotational time of stirring vane 5 be set as 30 seconds; When water temperature during more than 10 ℃ but less than 15 ℃ the rotational time of stirring vane 5 be set as 45 seconds; When water temperature is below 10 ℃, the rotational time of stirring vane 5 is set as 60 seconds.
In addition, if by the rice amount (volume) of washing rice be 1 o'clock the required water yield (volume) be defined as bath raio, exist while washing meter nutrition leak be suppressed to minimal bath raio.Figure 10 represents to change the nutrition retention rate of the rice of bath raio after washing rice.Bath raio when the characteristic curve K11 in Figure 10 represents that washing a meter time (rotational time of stirring vane 5) is 30 seconds and the relation of nutrition retention rate, the bath raio when characteristic curve K12 in Figure 10 represents that washing a meter time (rotational time of stirring vane 5) is 60 seconds and the relation of nutrition retention rate.In addition, here said nutrition refers to magnesium.Diagram P11, the P12 of characteristic curve K11, K12 in Figure 10 represents that bath raio is that after washing rice at 2.2 o'clock, nutrition is the most easily retained.On the other hand, the value of bath raio is that the value of diagram L11, the L12 of 1.6 o'clock and bath raio is that diagram R11, the R12 of 6.7 o'clock represents to be when bath raio is less than 2.2 and when bath raio is greater than 2.2 the trend that nutrition is easily run off.
Therefore, the level scale arranging for washing rice forming on inner bag 2, is preferably set to for respectively washing rice and measures that to make nutrition retention rate be maximum bath raio.In the present embodiment, the optimum value of bath raio is 2.2.But when the many and bath raio of the rice amount of washing is 2.2, water may overflow from inner bag 2.Now, be necessary to reduce the water yield, follow the minimizing bath raio of the water yield also to diminish, but as long as set required MIN reduction.
In addition, in said embodiment, as mentioned above, the standard of the rotational time of the stirring vane 5 while washing meter is 60 seconds.Figure 11 represents the relation of washing a meter time (rotational time of stirring vane 5) and nutrition retention rate of automatic rice-washing.As shown in Figure 11, through the automatic rice-washing of 10 seconds, with wash rice before compare nutritional amt and decline approximately 20%, through the automatic rice-washing of 60 seconds, with wash rice before compare nutritional amt and decline approximately 40%.But, through the upper nutritional amt retaining of the rice after the automatic rice-washing of 60 seconds, be 1.5 times of nutritional amt through retaining after manual washing rice.And after the automatic rice-washing of 10 minutes, with wash rice before compare nutritional amt and decline approximately 60%, also lower than the nutrition retention rate of manual washing rice.
Therefore as shown in Figure 11, compare with manual washing rice can guarantee more nutrition reservation amounts be automatic rice-washing wash meter time be 60 seconds with interior situation.Therefore,, in order to retain the nutrition of rice, when washing meter time, control preferably the optimum value of washing meter time was set as in 60 seconds.
And, with 60 seconds, with the interior meter time of washing, wash rice rice afterwards, by having confirmed the taste of rice below after the cooking running of narrating.Its result, meter time of washing is 60 seconds and washes meter time while being 30 seconds, all comparing rice with manual washing rice does not only have special rice bran taste, more has a meter fragrance on the contrary than manual washing rice.
Next, the automatic rice-washing running by described is washed to rice by the rice 11 in inner bag 2 after, with this, wash the action that the meter Jin Hang after rice cooks and describe for example.First, wash described in carrying out after rice and outwell and wash the used water of rice.Subsequently, by washing rice rice afterwards described in process, be reentered in inner bag 2 with the water of the use of cooking, inner bag 2 is packed in electric cooker main body 1, user's operating operation panel 32 afterwards, start cooking running (cooking), whether control part 31 judgements are covered 12 and are covered, if judgement covers 12, have covered, and by heater circuit 35, control heating part 3 and make heating part 3 start heating (cooking).
In described cooking running, control part 31 is controlled by the order of warming up, startup running, the running of cooking, the running of cooking rice over a slow fire, insulation running.
[warming up]
First, in warming up, by stirring motor 4, drive stirring vane 5 rotations, and the inside of stirring inner bag 2, simultaneously by heater circuit 35 to heating part the little electric power of 3 supply, and heat by 3 pairs of heating parts inner bag 2, and the electric power of controlling heating part 3 makes the temperature in inner bag 2 that temperature sensor 10 detects remain on 60 ℃, and carry out the warming up of the scheduled time.Now, the inside of stirring inner bag 2 by stirring vane 5, makes the heating object (meter He Shui) in inner bag 2 evenly keep target temperature (60 ℃), makes in this state rice absorb water and generates the glucose as taste composition.
In described warming up, 60 ℃ of setting is the temperature that amylolytic enzyme works most effectively, and makes the temperature in inner bag 2 remain on 60 ℃, keeps 15 minutes to 20 minutes.In the present embodiment, although the target temperature of warming up is set in 60 ℃, target temperature is not limited to this, can suitably set according to many conditions.
[starting running]
Next, stop stirring the running of motor 4, and then stop stirring vane 5, afterwards by heater circuit 35 to heating part the large electric power of 3 supply, and heat by 3 pairs of heating parts inner bag 2, make the temperature in inner bag 2 rise to the startup running of 100 ℃.At this, the temperature in inner bag 2 is detected by temperature sensor 10.
[running of cooking]
Next, the temperature from inner bag 2 reach 100 ℃ to the temperature in inner bag 2 reach 120 ℃ during, carry out by regulating the running of cooking that heat maintains boiling that adds of heating part 3.At this, if the water in inner bag 2 has not had no longer boiling, the temperature in inner bag 2 starts from 100 ℃ of risings.According to the described running of cooking, rice adds that heat and water are known as the chemical reaction of gelatinization, makes the β starch comprising in rice become α starch, cooks delicious rice.
[running of cooking rice over a slow fire]
And, if the temperature in inner bag 2 reaches 120 ℃, regulate heating part 3 add the running of cooking rice over a slow fire that heat carries out the scheduled time after, finish cooking (cooking) and transfer to insulation running.
As mentioned above, according to the electric cooker of present embodiment, the rice amount in the current value detection inner bag 2 that stirs motor 4 that flows through detecting by motor current test section 36, the amount of the rice 11 in inner bag 2 is more, in washing meter Yun Zhuan, the rotating speed that stirs motor 4 is controlled highlyer, therefore the rotating speed of the stirring vane 5 that is suitable for rice amount can be set, thereby the appropriate rice of washing can be carried out.In addition, the water temperature in the inner bag 2 detecting according to temperature sensor 10 high and low, controls driving time short, long of stirring motor 4, therefore can set the washing a meter time of water temperature that is suitable for washing rice, thereby can carry out the appropriate rice of washing.Therefore can either avoid washing that rice is insufficient can retain rice bran to a certain degree again, and can prevent that rotating speed due to stirring vane 5 is too high and cause that the grain of rice is damaged, can make the rice boiling keep the original fragrance of rice.
In addition, in said embodiment, although the motor current test section 36 that detection is flow through to the current value that stirs motor 4 is used as a rice amount test section, the rice that also can detect by the following method in inner bag 2 is measured.That is, on casing 20, by spring member etc., support mobile member, and make the bottom butt of this mobile member and inner bag 2, and the displacement of the described mobile member of measuring measurement device and being subjected to displacement because the rice in inner bag 2 measures with deflection.In addition, in said embodiment, according to the rice amount detecting number regulate by stages the height of the rotating speed that stirs motor 4, but also can regulate continuously according to rice amount the height of the rotating speed that stirs motor 4.In addition, in said embodiment, the temperature detecting according to temperature sensor 10 is controlled the length of the rotational time that stirs motor 4 by stages, but the temperature that also can detect according to temperature sensor 10 is controlled the length of the rotational time that stirs motor 4 continuously.
In addition, in said embodiment, as as described in illustrate in flow chart, the rotating speed of the stirring vane 5 of controlling according to the rice amount control part 31 detecting is in order to carry out the appropriate a series of rotating speeds (350rpm, 450rpm, 550rpm) that rice is set of washing, but described a series of rotating speeds (350rpm, 450rpm, 550rpm) also can be regulated by user.For example: on the guidance panel 32 as input operation part, be provided as " slightly the washing " of washing meter Cai Dan, " standard is washed ", the button such as " fully wash ", be used to specify and wash meter Cheng Du, when " standard is washed " button is carried out each rotating speed illustrating in each step at described flow chart on time, when " slightly washing " button is carried out a series of rotating speed (350rpm than described flow chart on time, 450rpm, 550rpm) low 10% rotating speed for example, when " fully washing " button is carried out a series of rotating speed (350rpm than described flow chart on time, 450rpm, 550rpm) high 10% rotating speed for example.Thus, user can regulate the reservation amount of rice bran, can wash rice according to user's hobby.In addition, " slightly washing ", " standard is washed ", " fully washing " three phases can be not only set, more stage adjusting rotary speed also can be set.
In addition, in said embodiment, the magnetic coupling that the rotation of stirring motor 4 consists of the magnet 7 of rotor 6 and the magnet of stirring vane 58 is passed to stirring vane 5, but also can substitute the magnetic coupling that magnet 7 and magnet 8 form, when inner bag 2 packs in electric cooker main body 1, make stirring vane 5 chimeric with the upper rotor 6 of installing of the rotating shaft 4a that stirs motor 4, but do not carry out the relative rotation of machinery.Now, in the chimeric structure of stirring vane 5 and rotor 6, in the place setting that connects inner bag 2, prevent the sealing device leaking.In addition, substitute and stir motor 4 and rotor 6, also can, for example as the fixed electromagnetic yoke of synchronous motor, adopt fixed electromagnetic yoke, be wrapped in a plurality of coils on this fixed electromagnetic yoke and make described a plurality of coil produce the AC power of rotating excitation field.By described fixed electromagnetic yoke and AC power, produce rotating excitation field, can drive stirring vane 5 rotations of magnetic couple.
In addition, the present invention is not limited to described embodiment, also can with various modes of texturing, implement within the scope of the invention.
