Specifically, referring to Fig.1 5, when detection device 2 is temperature sensor 22, temperature sensor 22 for directly or
The temperature of soup (such as thin rice gruel) in detection cooking cavity indirectly.For the ease of installation, temperature sensor 22 may be mounted at pot
It is connected in lid 4 and with the gas blanket of cooking cavity inner top to detect the vapor (steam) temperature of cooking cavity inner top, at this point it is possible to by pushing away
The method led detects the soup temperature in cooking cavity indirectly.For example, the temperature value that temperature sensor 22 can be detected is plus steaming
The difference of stripping temperature and soup temperature to obtain the soup temperature in cooking cavity indirectly.
Referring to Fig.1 and Figure 14, pressure relief device 1 are used to make cooking cavity exhaust pressure relief, and specifically, pressure relief device 1 is for making to cook
Intracavitary pressure of preparing food maintains rated pressure PVolumeBelow, that is to say, that when the pressure in cooking cavity reaches rated pressure PVolumeMore than
When, the pressure (such as steam pressure) in cooking cavity can drive the automatic exhaust pressure relief of pressure relief device 1, so that it is guaranteed that in cooking cavity
Pressure be consistently less than equal to rated pressure PVolume, specifically, when the pressure in cooking cavity reaches rated pressure PVolumeWhen, in cooking cavity
Soup in rated pressure PVolumeUnder with boiling temperature TBoilingBoiling, wherein rated pressure PVolumeGreater than one standard atmospheric pressure, i.e. PVolume>
1atm。
Pressure relief device 1 is configured to detect soup pressure rise in cooking cavity to bumping pressure when pressure sensor 21
PBumpingWhen, pressure relief device 1 forces pressure release so that soup bumping in cooking cavity, wherein PBumping< PVolume.Alternatively, pressure relief device 1 constructs

Gas-bearing formation progress heat transfer, heat transfer rate are very slow, to cause the air layer close to soup surface and the sky far from soup surface
The temperature difference between gas-bearing formation is larger, will be in cooking cavity by control pressure relief device 1 after the temperature of soup is increased to 90 DEG C or more
Cold air be quickly discharged into outside electric cooker so that the air themperature in cooking cavity is uniformly distributed, improve cooking efficiency,
Improve rice discoloration problem caused by cold air exists.
For the ease of installation, temperature sensor 22 may be mounted in pot lid 4 and connect with the gas blanket of cooking cavity inner top
The gas temperature of detection cooking cavity inner top is passed to, at this point it is possible to detect the soup in cooking cavity indirectly by the method derived
Temperature.In this way, before carrying out the exhausting cold air stage, due to the air layer close to soup surface and far from the air layer on soup surface
The temperature difference it is larger, temperature difference T can be increased to 10 DEG C~25 DEG C, at this point, detecting the gas in cooking cavity when temperature sensor 22
When temperature is increased to 90 DEG C-Δ T, it is believed that the soup temperature in cooking cavity is increased to 90 DEG C of delivery temperature, at this time can be into

Below with reference to the accompanying drawings 1 cooking control method for describing electric cooker according to an embodiment of the present invention, cross shown in Fig. 1
Axis represents the time, and the longitudinal axis in left side represents cooking cavity bottom temp, and the longitudinal axis on right side represents culinary art cavity pressure, temperature curve T
It represents cooking cavity bottom temp to change with time, pressure curve P represents culinary art cavity pressure and changes with time.
Specifically, the bottom outside cooking cavity can be equipped with for the heating device to cooking cavity bottom-heated and for detecting
The temperature sensor (temperature curve T shown in Fig. 1 is exactly to be measured by the temperature sensor) of cooking cavity bottom temp, according to
The temperature of cooking cavity bottom change with time the entire process of cooking can be roughly divided into warm-up phase S1, water suction stage S2,
Heating period S3, bumping stage S4, boiling stage S5 and the stage S6 of cooking rice over a slow fire totally six stages, in addition, after the stage S6 that cooks rice over a slow fire
There can also be holding stage S7.Certainly, the invention is not limited thereto, and heating device can not also be located at the bottom of cooking cavity.
First stage: warm-up phase S1
After the rice-cooking function for starting electric cooker, cooking cavity can be heated by heating device, so that in cooking cavity
Thin rice gruel temperature by room temperature be increased to water suction temperature TIt inhales, optionally, 40 DEG C≤TIt inhales≤60℃.Warm-up phase S1 is main as a result,
Effect is by quickly heating the optimum temperature section for making thin rice gruel be warming up to suitable grain of rice water suction.
Second stage: water suction stage S2
After warm-up phase S1, the heating of low-power can be carried out by heating device, so that the thin rice gruel in cooking cavity
Temperature maintains TIt inhales, and continue one section of duration t1, it is preferable that 5min≤t1≤30min.As a result, water suction the stage can make the grain of rice into
Row fully absorbs water, so that the moisture content of rice guaranteed to be increased to the level 20%~28% after the water suction stage.Separately
Outside, thin rice gruel temperature is maintained to the optimum temperature T of suitable grain of rice water suctionIt inhalesPurpose be: thin rice gruel temperature is too low to will lead to the grain of rice
Absorption speed reduces, and causes absorbent time too long, and the too high grain of rice that will lead to of temperature becomes sticky in water suction phase table batter, too early shape
At the rice group of agglomeration, the grain of rice water suction of rice cluster centre is hindered.
Phase III: heating period S3
After water suction stage S2, powerful heating can be carried out by heating device, so that the thin rice gruel in cooking cavity
Temperature is by TIt inhalesThe pressure being quickly increased in cooking cavity reaches preset migration bumping pressure PBumping, while the soup in cooking cavity
Temperature is by TIt inhalesQuickly it is increased to preset migration bumping temperature TBumping。
In this stage, on the one hand rice will continue to water swelling, on the other hand since thin rice gruel temperature is higher, rice surface section
Position can start gelatinization and become sticky, and cause the grain of rice that can be bonded together to form rice group, and the grain of rice intermediate in rice group can be because of outer rice and wheat
The encirclement of group and absorption speed decline or the difficult problem of water suction occurs.
In addition, in the process, with continuing for heating process, the coolant-temperature gage in pot body is higher and higher, at this time in water
Gas solubility can be gradually reduced with temperature raising, be floated in the form of bubble so that the gas dissolved originally in water is gradually precipitated
It rises in the closed cavity in addition to thin rice gruel that is discharged into cooking cavity, since gas can not circulate and substantially in closed cavity
Convection current does not occur, on the one hand, it will lead to the air pressure in closed cavity and rise to greater than outside atmosphere pressure, on the other hand, by
In the meter Shui Yu being heated in gas pot body in closed cavity closed air chamber only leans on air layer to carry out heat transfer, heat transfer
Speed is very slow, will cause the air themperature in cooking cavity far from thin rice gruel surface and generates ratio with the air themperature close to thin rice gruel surface
Biggish temperature difference T, Δ T difference size can due to the amount of the structure space of product or rice of cooking difference different, general difference
Different value is 10 DEG C~25 DEG C, the gas temperature and thin rice gruel of the cooking cavity for causing the temperature sensor 22 being arranged in pot lid 4 to detect
Actual temperature it is widely different.
Therefore, row's cold air process can be added in the heating period, i.e., by forcibly opening exhaust outlet 40
So that the cold air in cooking cavity is discharged to outside cooking cavity, on the one hand make gas temperature in cooking cavity far from thin rice gruel surface with
Gas temperature close to thin rice gruel surface is more nearly, so that the gas temperature that temperature sensor 22 detects is closer to thin rice gruel temperature,
On the other hand discharge cold air after can reduce cold air there are problems that and caused by rice discoloration.
Specifically, in heating period S3, when up to 90 DEG C~98 DEG C of thin rice gruel temperature rise, or when pressure sensor 21 detects
When pressure rise in cooking cavity is to 1.01atm~1.1atm, exhaust outlet 40 is opened by control pressure relief device 1, and keeps
Certain duration t2, wherein the duration t of 40 exhausting cold air of exhaust outlet2It can be according to the volume of cooking cavity and the amount of rice come specific
Setting, generally, t2Meet: 1s≤t2≤ 30s, so that compulsory circulation is realized with electric cooker ambient atmosphere in cooking cavity, it will
Cold air in cooking cavity is quickly discharged into outside electric cooker.
Fourth stage: bumping stage S4
A bumping agitating procedure S4 is inserted into before starting after heating period S3 with boiling stage S5, by unexpected
Pressure release variation, so that the thin rice gruel in cooking cavity generates the effect of bumping to stir rice and scald progress tumbling motion, to break up knot
The rice group of block, the uniformity for promoting whole pot rice to absorb water and heat.
When pressure sensor 21 detects in cooking cavity thin rice gruel pressure rise to bumping pressure PBumpingWhen, or when temperature passes
Sensor 22 detects that thin rice gruel temperature is increased to bumping temperature T in cooking cavityBumpingWhen, by controlling the above-mentioned movement of pressure relief device 1 at least
Exhaust outlet 40 is opened at least once, carries out pressure release process, make by once (each duration can be arranged according to actual requirement)
Cooking cavity and electric cooker outside are connected to so that the pressure in cooking cavity is reduced to normal atmosphere pressure condition (such as one suddenly
Standard atmospheric pressure 1atm), that is to say, that the pressure in cooking cavity is forcibly dropped to by normal pressure state by the short time suddenly,
So that the thin rice gruel in cooking cavity acutely boils suddenly since temperature is higher than the boiling temperature of normal atmosphere pressure, generates stirring and turn over
The effect risen is generated with the impact force of bumping, so that the grain of rice is seethed stirring to break up the heating period due to gelatinization of grain of rice surface becomes sticky
Caused by agglomeration rice group, promote rice entirety water suction consistency and heating uniformity.
Certainly, the invention is not limited thereto, is controlled by way of control pressure release number and each pressure release duration whole prominent
Other than the duration of boiling stage S4, can also by control repeatedly pressure release work total duration come control whole bumping stage S4 when
It is long.
Wherein, bumping pressure PBumpingClose to the rated pressure P of pressure limiting valve 11Volume, for instance, it is preferred that PBumpingMeet: PVolume-
0.2atm≤PBumping≤PVolume- 0.05atm, at this point, when pressure sensor 21 detects the pressure rise in cooking cavity to close to pressure limiting
The rated pressure P of valve 11VolumeWhen, alternatively, when temperature sensor 22 detects that the soup temperature in cooking cavity is increased to pressure limiting valve 11
Rated pressure PVolumeCorresponding boiling temperature T under stateBoilingWhen (preferably, 1≤Δ T '≤5) Δ T ', bumping behaviour can be started
Make, wherein boiling temperature TBoilingBy the effects of air pressure in cooking cavity, boiling temperature T under different pressures stateBoilingDifference is specific right
It should be related to and be shown in Table 1.
Table .1: the boiling point of water and the corresponding relationship of atmospheric pressure value
| Atmospheric pressure value P/ (a standard atmospheric pressure atm) | Boiling temperature T/ (degree Celsius DEG C) |
| 1.0 | 100 |
| 1.1 | 102.4 |
| 1.2 | 104.8 |
| 1.3 | 107.3 |
| 1.4 | 109.7 |
| 1.5 | 111.6 |
| 1.6 | 113.4 |
| 1.7 | 115.3 |
In addition, it is necessary to explanation, when heating period S3 includes row's cold air process, after exhausting cold air process S31,
Exhaust outlet 40 is set to closed state again, and the air pressure in cooking cavity reverts to normal atmosphere pressure condition at this time, with heating
Continue, when thin rice gruel temperature is increased to 100 DEG C, the water in thin rice gruel can generate the boiling of short time, cause a large amount of water vapour into
Enter into cooking cavity in the closed cavity for accommodating gas, so that the air pressure of sealing cavity increases rapidly, the water in pot body can be with
The raising of pressure reverts to the state that do not boil again, when pressure sensor 21 detects the pressure rise in cooking cavity to PBumpingWhen,
Start bumping agitating procedure again.Or when temperature sensor 22 detects that thin rice gruel temperature is increased to T in cooking cavityBumpingWhen, then start
Bumping agitating procedure, at this point, due to the exhausting cold air process S31 of back, even if the temperature that temperature sensor 22 detects is thin rice gruel
The gas temperature of top can also be approximately considered the temperature equal to thin rice gruel.
5th stage: boiling stage S5
Exhaust outlet 40 is closed after bumping stage S4, that is to say, that after forced exhaust preset duration t0, stop the row of pressure
Gas maintains certain heating power, so that the thin rice gruel in cooking cavity maintains rated pressure PVolumeUnder, with rated pressure PVolumeIt is corresponding
Boiling temperature TBoilingConstantly boiling, until cooking cavity in dissociate moisture content completely by rice absorb or with after explosive evaporation (i.e.
After soup is boiled dry), the temperature of cooking cavity bottom persistently quickly rises to preset migration temperature T with heatingIt moves, it is preferable that
120℃≤TIt moves≤ 130 DEG C, in this stage, the high temperature that the grain of rice maintains 100 DEG C or more for a long time is gelatinized, by the β of rice densification
Starch is sufficiently converted into the loose α starch structure that can be digested.
6th stage: cook rice over a slow fire stage S6
Self-boiling stage S5 terminates until cooking terminates one section of t that holds time of settingDimension(preferably, 3min≤tDimension≤
15min), this period, electric cooker can be heated with relatively low power, or not heated in directly such as cooking cavity
Accumulation of heat persistently carries out waste heat benefit to rice and cooks a meal, to further promote the gelatinization of rice, promotes the mouthfeel of rice.Here, it needs
Illustrate, low-power heating is that the speed heated is different with the difference that high power heats, such as low-power heating can be managed
To reach a certain temperature with slower speed, high power heating can be understood as reaching above-mentioned temperature with faster speed solution.
