Relation between putting.Additionally, the example of the various specific technique that provides of this utility model and material, but this area is common
Technical staff can be appreciated that the applicable property of other techniques and/or the use of other materials.
Below with reference to the accompanying drawings 1 and 2 descriptions are according to the electric cooker of this utility model embodiment.
According to the electric cooker of this utility model embodiment, can include：Cooker body (not shown), pot lid 4, pressure relief device 1,
Heater (not shown) and control module.
Specifically, cooker body includes interior pot and outer pot, and wherein, interior pot is located in outer pot and has the culinary art for the food materials that boil
Chamber, outer pot is located at for pot in supporting outside interior pot, and pot lid 4 can be opened and closed to be located to open and tube wall cooking cavity in cooker body, its
In, pot lid 4 can be connected by hinge with outer pot, and hinge guarantees that pot lid 4 is free to rotate around the afterbody axis of outer pot, heating dress
Put it is so structured that converting electrical energy into the device of heat energy to realize the heating to cooking cavity, wherein, heater can be located at
It is also possible to be located in pot lid in cooker body, can also be located in cooker body and pot lid simultaneously, below, only interior pot is located at heater
Illustrate as a example the electric cooker of outer bottom.
Wherein, pressure relief device 1 is located at the pressure in pot lid 4 for regulation and control culinary art intracavity, and wherein, pressure relief device 1 is at least
There is " active voltage regulation function ", to force cooking cavity exhaust pressure relief；Certainly, pressure relief device 1 can also have " passive pressure regulation work(
Can ", so that the automatic exhaust pressure relief of cooking cavity.Concrete analysis is as follows：
" passive voltage regulation function " refers to：By cooking the opening and closing of the Steam pressure control pressure relief device 1 of intracavity.Concrete and
Speech, (before the rice water that i.e. culinary art intracavity boils is not up to boiling stage S5), the pressure of culinary art intracavity before electric cooker does not play pressure
Less than default boiling pressure P, now, pressure relief device 1 cannot be opened by the steam pressure of culinary art intracavity, and cooking cavity is in closing and increases
Pressure condition；After supercharging a period of time, electric cooker plays pressure (rice water that i.e. culinary art intracavity boils reaches boiling stage S5), now, cooks
The pressure of intracavity of preparing food can exceed default boiling pressure P, thus pressure relief device 1 can be opened by the steam pressure cooking intracavity,
Cooking cavity is made to be in non-tight state with outside exhaust pressure relief；After pressure release for a period of time, culinary art intracavity pressure return to low
In default boiling pressure P, now, pressure relief device 1 cannot be opened, thus pressure relief device 1 can by the steam pressure of culinary art intracavity again
To be again switched off so that cooking cavity is again sealed off being pressurized；So circulate repeatedly, in the boiling stage S5 cooking, pressure relief device 1
May insure that the pressure of culinary art intracavity remains at and fluctuate (as shown in boiling stage S5 in Fig. 2) near default boiling pressure P.
Here, it should be noted that the concept of boiling stage S5 will be described below.
Here it is possible to be understood by, preset boiling pressure P and be more than atmospheric pressure (such as 1 standard atmosphere outside electric cooker
Pressure), thus when pressure relief device 1 is opened by steam pressure after, cooking cavity can outside exhaust pressure relief automatically.Preferably, preset boiling
The span rising pressure P is 1.2atm～1.4atm.
In a specific example of the present utility model, pot lid 4 could be formed with connection cooking cavity inside and electric cooker
Outside through hole (air vent 40 for example hereinafter described), the sectional area of through hole is S, and pressure relief device 1 includes pressure limiting valve 11, pressure limiting
Valve 11 is used for controlling whether the opening and closing of through hole connects (opening and closing controlling pressure relief device 1) to limit cooking cavity with extraneous air,
For example, pressure limiting valve 11 can be the rigid bead of m for a quality, when rigid bead being located at the top of through hole, Ke Yiyi
The ratio of the sectional area of the deadweight by bead and through hole to limit default boiling pressure P, that is, is preset boiling pressure P and is met：P=mg/
S.Thus, when the pressure cooking intracavity exceedes default boiling pressure P, rigid bead is with regard to the steam pressure jack-up of cooked intracavity
To open through hole (even if pressure relief device 1 is opened), when the pressure cooking intracavity is less than default boiling pressure P, rigid bead is just
Can automatically fall under gravity to close through hole (even if pressure relief device 1 is closed).
" active voltage regulation function " refers to：The opening and closing being controlled pressure relief device 1 by way of artificial is cooked with forced adjustment
The pressure of intracavity.So, during electric cooker is cooked, if necessary to cooking cavity pressure release it is possible to by way of artificial
Pressure relief device 1 is opened, so that the outside exhaust pressure relief of cooking cavity is that is to say, that pressure relief device can forcibly be opened in good time
1, so that the high steam of culinary art intracavity is discharged, thus making the pressure of culinary art intracavity reduce rapidly by way of quick row's steam
(being for example reduced to equal with the atmospheric pressure outside electric cooker).Thus, it is possible to be reliably achieved the bumping stage S4 cooking and
Exhausting cold air operation S31.Here, it should be noted that the concept of bumping stage S4 and exhausting cold air operation S31 will be hereinafter detailed
State.
Here it is possible to be understood by, the artificial pressure forcing culinary art intracavity during pressure release should be more than big outside electric cooker
Air pressure is strong (such as 1 normal atmosphere), thus after pressure relief device 1 is by artificial positive opening, cooking cavity can outwards be let out in aerofluxuss
Pressure.
It is possible to cook intracavity when when pressure relief device 1 had not only had passive voltage regulation function but also there is active voltage regulation function
Carry out pressure release that is to say, that the steam pressure in culinary art intracavity is not enough to fill pressure release when pressure is not less than default boiling pressure P
When putting 1 and opening, artificially pressure relief device 1 can be opened, cooking cavity exhaust pressure relief be forced by active voltage regulation function, thus
Realize bumping stage S4 and exhausting cold air operation S31；And when the pressure cooking intracavity exceedes default boiling pressure P, cook intracavity
Steam pressure be enough to pressure relief device 1 is opened, you can so that the automatic exhaust pressure relief of cooking cavity is made by passive voltage regulation function, thus
Realize boiling stage S5.
So, when electric cooker is cooked, first exhausting cold air work can be realized using the active voltage regulation function of pressure relief device 1
Sequence S31 and bumping stage S4, then boiling stage S5 is realized using the passive voltage regulation function of pressure relief device 1, so that it is guaranteed that cook
It is smoothed out, improve culinary art effect.Further, since pressure relief device 1 has active voltage regulation function and passive voltage regulation function concurrently, so that
Electric cooker overall structure is simple, easy to process, low cost of manufacture, functional reliability is high.
In a specific example of the present utility model, as shown in figure 1, connection culinary art intracavity be could be formed with pot lid 4
Portion and the pressure relief opening (air vent 40 for example hereinafter described) outside electric cooker, pressure relief device 1 includes pressure limiting valve 11 and pressure release machine
Structure 12, pressure limiting valve 11 can be the rigid bead being located at pressure relief opening top, and pressure relief mechanism 12 is used for controlling rigid bead to be to close
Still open pressure relief opening, thus forcing to control the opening and closing of pressure relief device 1.
In another specific example of the present utility model, when pressure relief device 1 had not only had passive voltage regulation function but also there is master
During dynamic voltage regulation function, through hole and pressure relief opening can be same mouth, i.e. air vent 40, and pressure relief device 1 now includes pressure limiting valve 11
With pressure relief mechanism 12, pressure limiting valve 11 under gravity press seal at the top of air vent 40, pressure relief mechanism 12 is used for artificial control
Pressure limiting valve 11 processed opens air vent 40 or cuts out air vent 40.Certainly, this utility model not limited to this, can also be by setting
Put extra pressure relief device above-mentioned " active voltage regulation function " is implemented separately, I will not elaborate.

Change becomes sticky, and leads to the grain of rice can be bonded together formation rice group, and the grain of rice being in the middle of rice group can be because of the encirclement of outside rice group
Lead to absorption speed to decline or hinder water suction.
Table .1：The boiling point of water and the corresponding relation of atmospheric pressure value
| Atmospheric pressure value P/ (a normal atmosphere 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 |

Wherein, boiling stage S5 be culinary art intracavity pressure reach pressure limiting valve 11 restriction default boiling pressure P-state and
The soup temperature of culinary art intracavity is the stage of boiling temperature T (as shown in table 1), now " the passive tune according to above-mentioned pressure relief device 1
Pressure function ", even if heater continues cooking cavity is heated, the temperature of liquid of culinary art intracavity also will not continue to rise, and
It is maintained at constantly boiling gelatinizing so that rice absorbs water at high operating temperatures of default boiling temperature T small range fluctuation nearby；This
Stage until culinary art intracavity dissociate moisture content absorbed by rice completely or with explosive evaporation after, with heating persistently carry out,
After the temperature of cooking cavity bottom quickly rises to default migration temperature T3 (being traditionally arranged to be 120～130 DEG C), heater turns
Enter the state that little firepower is heated or not heated.
Wherein, the stage S6 that cooks rice over a slow fire terminates for boiling stage S5 until the one section of maintenance duration t2 terminating to arrange that cooks is (general
For 3～15 minutes) stage, this period, electric cooker with than relatively low power heating or do not heat, and directly used cooking cavity
Accumulation of heat persistently rice is carried out waste heat mend cook a meal, further promote gelatinizing.
Based on the research to above-mentioned process of cooking, applicant have surprisingly discovered that, with boiling rank after in the heating period, S3 terminates
Before section S5 starts, may be inserted into a bumping agitating procedure S4, by unexpected pressure release change so that cooking the rice of intracavity
Water produces the effect of bumping, carries out tumbling motion to stir meter Shui, such that it is able to break up the rice group of caking, promotes whole pot rice to inhale
Water and the uniformity of heating.
Therefore, the cooking control method of the electric cooker according to this utility model embodiment, may comprise steps of：According to
Treat that amount V of cooked food obtains corresponding bumping temperature TBumping, when the soup temperature of culinary art intracavity is increased to bumping temperature T bumping
When (and or, corresponding bumping pressure P is obtained according to amount V treating cooked foodBumping, when the pressure of culinary art intracavity is increased to bumping pressure
Strong PBumpingWhen), make the outside exhaust pressure relief of cooking cavity so that the soup bumping of cooking cavity, wherein, wherein, PBumping＜ P, TBumping＜ T.By

The continuing of journey, the soup temperature more and more higher in cooking cavity, now raise with temperature can progressively for the gas solubility in soup
Reduce so that the gas that originally dissolves in soup is gradually separated out to be floated in the form of bubble and is discharged in cooking cavity.With precipitation
The gas of discharge increases, and the air pressure in cooking cavity can be gradually increasing；Simultaneously because gas does not occur convection current substantially in cooking cavity, cook
Prepare food heated rice water liquid and airtight air chamber in chamber only carries out conduction of heat by air layer, and heat transfer rate is very slow, can cause
There is ratio larger (such as 10～25 in the air layer of the air layer and the detection means region arranging away from soup face of pressing close to soup face
DEG C) temp. difference field, thus leading to the soup temperature that is converted into of air themperature of detection means 2 detection and actual soup temperature contrast
Very big, lead to temperature-sensitive result to be forbidden.
The stage casing that therefore, it can heating period S3 arranges operation S31 of row's cold air, is filled by positive opening pressure release
Putting 1 makes air vent 40 exhaust pressure relief so that culinary art intracavity cold air can be discharged to outside cooking cavity, so so that
The culinary art air away from the water surface for the intracavity is close with the air themperature close to the water surface, that is, so that levels air themperature in cooking cavity is become
In being uniformly distributed, thus the soup temperature more closing to reality of the air themperature conversion of detection means 2 detection on the one hand can be made
Soup temperature, improves temperature-sensitive accuracy；On the other hand, after discharging cold air, cold air can also be reduced and exist and cause
Rice discoloration problem.
Thus, when electric cooker is in heating period S3, when the soup temperature of culinary art intracavity is increased to delivery temperature TRowWith/
Or when the pressure of culinary art intracavity is increased to drain pressure PRowWhen, the outside exhaust pressure relief of cooking cavity can be forced, for example, control pressure release
