Following disclosure provides many different embodiments or example for realizing different structure of the present utility model.For Simplification disclosure of the present utility model, is hereinafter described to the part and setting of specific examples.Certainly, they only show Example, and purpose does not lie in restriction this utility model.Additionally, this utility model can in different examples repeat reference numerals And/or letter.This repeat to be for purposes of simplicity and clarity, itself do not indicate discussed various embodiment and/or set 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.
Amount V that control module is used for according to treating cooked food obtains corresponding bumping temperature TBumpingAnd/or bumping pressure PBumping, And the soup temperature in culinary art intracavity is increased to bumping temperature TBumpingWhen and/or culinary art intracavity pressure be increased to bumping pressure PBumpingWhen, control module forces pressure relief device 1 to be opened, to force the outside exhaust pressure relief of cooking cavity, so that the soup of culinary art intracavity Liquid bumping that is to say, that control module can judge rational bumping time point according to the number treating cooked food, thus It is effectively realized bumping stage S4, improve effect of cooking.Wherein, bumping temperature TBumpingLess than default boiling temperature T (rank of seething with excitement The soup boiling temperature of culinary art intracavity during section S5), bumping pressure PBumping(cook during boiling stage S5 less than default boiling pressure P The pressure of intracavity).
Specifically, control module can include:Judgment means, detection means 2 and control device 3, wherein, judgment means structure Cause for judging to cook amount V that intracavity treats cooked food, and corresponding bumping temperature is obtained according to amount V treating cooked food TBumpingAnd/or bumping pressure PBumping, detection means 2 (such as temperature sensor and/or pressure transducer) is configured for detection and cooks The soup temperature of intracavity of preparing food and/or the pressure of culinary art intracavity, control device 3 and judgment means, detection means 2 and pressure release dress Put 1 to be connected, and the temperature being configured to detect in detection means 2 reaches bumping temperature T of judgment means acquisitionBumpingAnd/or inspection The pressure that survey device 2 detects reaches the bumping pressure P of judgment means acquisitionBumpingWhen, control pressure relief device 1 to make cooking cavity outside Exhaust pressure relief is that is to say, that control device can be according to the signal of detection means 2 and judgment means transmission, through routine processes The control signal to pressure relief device 1 for the computing output, to control pressure relief mechanism 12 to force to beat by air vent 40 in rational time point Open.Thus, the structure of control module is simple, and functional reliability is high.
Specifically, the judgment means according to this utility model embodiment, can be sentenced by way of receiving and/or detecting Disconnected culinary art intracavity treats amount V of cooked food, and according to treating amount V of cooked food, by presetting method (for example with default synopsis Compare, or substitute into pre-set programs conversion etc.) obtain corresponding bumping temperature TBumpingAnd/or bumping pressure PBumping.
Wherein, when the mode that judgment means are configured by reception judges to cook intracavity whne amount V of cooked food, judge Device can receive from amount V treating cooked food of user input that is to say, that user can input to judgment means waits to boil Amount V of food, so that judgment means are calculated by its default program, to draw corresponding bumping temperature TBumpingAnd/or it is prominent Boiling pressure PBumping.
Wherein, when the mode that judgment means are configured by detection judges to cook intracavity whne amount V of cooked food, judge Device can voluntarily detect amount V treating cooked food that is to say, that judgment means have the work(that the amount of cooked food is treated in detection Can, first to carry out detecting decision content V, then calculated by its default program, drawn corresponding bumping temperature TBumpingAnd/or Bumping pressure PBumping.Wherein, when judgment means have detection whne the function of the amount of cooked food, judgment means can have biography Sensor.
For example in an example of the present utility model, judgment means can have weight sensor, and weight sensor can To detect the weight change of cooking cavity, now, judgment means can judge to treat cooked food by the weight change of cooking cavity Amount.Here it is possible to be understood by, this detection process was carried out before bumping stage S4 can be that is to say, that in heating period S3 Or carry out before heating period S3 all may be used.
And for example in another example of the present utility model, judgment means can also have imageing sensor, image sensing Device can detect the space hold situation of culinary art intracavity, and now, judgment means can be sentenced by the space hold situation of cooking cavity The disconnected amount treating cooked food.Here it is possible to be understood by, this detection process was carried out before bumping stage S4, that is, Say, carried out all may be used before heating period S3 or heating period S3.
For another example, in another example of the present utility model, judgment means can also have temperature sensor and timer, Temperature sensor can detect the soup temperature rise of culinary art intracavity, and timer can detect heating duration, thus, it is possible to by detection Temperature rise in scheduled duration judges to treat the amount of cooked food or judges to wait to boil by detecting the duration needed for predetermined temperature rise The amount of food.In this example, electric cooker can also include:Regulation device, regulation device is connected with heater to regulate and control to add The heating power of thermal.Specifically, when electric cooker is in heating period S3, regulation device can regulate and control heater with Firm power heats to cooking cavity, and thus, the soup temperature that heating period S3 cooks intracavity linearly rises.In addition, adjusting Control device can also be heated with fixing heating Power Regulation ratio, and now the ascendant trend of the soup temperature of culinary art intracavity also has rule Rule can be followed.Thus, when electric cooker is in heating period S3, judge module just can judge that culinary art intracavity treats the amount of cooked food V.Thus, judging nicety rate is higher, and culinary art effect is more preferable.
Thus, it is in firm power and/or constant heating Power Regulation ratio in the heating period S3 being heated in electric cooker, On the one hand, can judge to treat the amount of cooked food according to the heating duration that culinary art intracavity soup temperature rises needed for predetermined temperature difference V that is to say, that by detection rise the lasting duration Δ t of temperature difference T judge meter Shui Liang number, Δ t longer representative rice The water yield is more, conversely, Δ t is shorter, and to represent meter Shui Liang fewer;On the other hand, can also be according to heating scheduled duration culinary art intracavity soup The temperature difference that liquid rises is judging to treat amount V of cooked food that is to say, that sentencing by detecting temperature difference T that risen of duration Δ t The number of disconnected meter Shui Liang, the less meter Shui Liang that represents of Δ T is more, conversely, Δ T is bigger, and to represent meter Shui Liang fewer.
Certainly, this utility model not limited to this, in other embodiments of the invention, are in electric cooker with firm power And/or constant heating Power Regulation ratio in the heating period S3 being heated, on the one hand, can also be risen pre- according to pressure in cooking cavity Determine needed for pressure difference heating duration come to judge to treat amount V of cooked food that is to say, that by detection rise pressure difference Δ P ' institute Judging the number of meter Shui Liang, the longer meter Shui Liang that represents of Δ t ' is more, conversely, Δ t ' is shorter represents meter Shui for lasting duration Δ t ' Amount is fewer;On the other hand, can also judge to wait the food that boils according to the pressure difference that pressure in heating scheduled duration cooking cavity rises Amount V of thing that is to say, that by detect the pressure difference Δ P ' that duration Δ t ' is risen to judge meter Shui Liang number, Δ P ' is more The little meter Shui Liang that represents is more, conversely, Δ P ' is bigger, and to represent meter Shui Liang fewer.
Below with reference to the accompanying drawings 1 and 2 descriptions are according to the cooking control method of the electric cooker of this utility model embodiment.
Electric cooker according to this utility model above-described embodiment can adopt the cooking control method of the present embodiment to be boiled Meal, thus, electric cooker can realize bumping stirring by the mutation of pressure during cooking, thus breaing up the rice group of caking, Realize the uniform heating of rice, improve the effect that boils of rice.Here it is necessary first to illustrate, as shown in Fig. 2 electric cooker During cooking, the divided stages of can substantially entirely being cooked of the variable condition according to cooking cavity bottom temp and time are pre- Hot stage S1, water suction stage S2, heating period S3, the boiling stage S5 and stage S6 of cooking rice over a slow fire totally five stages.
Wherein, warm-up phase S1 is to be raised by room temperature by the water temperature that heating makes culinary art intracavity to reach preset value T1 (typically For 40~60 DEG C) process.
Wherein, water suction stage S2 is to keep a timing by the water temperature that lower powered heating makes culinary art intracavity in T1 temperature The state of long t1 (generally 5~30 minutes), the now continuous imbibition of rice.
Wherein, heating period S3 is by powerful heating so that the water temperature of culinary art intracavity reaches boiling by quick rising of T1 (T2 is affected by the pressure of culinary art intracavity, and under different pressures state, boiling temperature is different, and specific corresponding to relation is shown in Table to rise temperature T 1), may proceed to imbibition in this stage one side rice, on the other hand because temperature is higher, rice top layer position can start to paste 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.

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 This, can be according to the different adjustment bumping mixing effects of rice amount, thus reaching more preferable culinary art effect.
Specifically, when the soup temperature that detection means 2 detects culinary art intracavity is increased to the bumping of judgment means judgement Temperature TBumpingWhen, and/or when the pressure of culinary art intracavity is increased to the bumping pressure P of judgment means judgementBumpingWhen, control device controls Pressure relief mechanism 12 Forced Decompression Valve 11 at least opens air vent 40 at least one times, to realize forcing pressure release so that cooking intracavity Pressure is reduced to suddenly electric cooker external pressure (such as 1 normal atmosphere), so that the soup temperature of culinary art intracavity is unexpected Higher than the corresponding boiling temperature of external pressure, thus producing the effect that acutely boiling, stirring are rolled suddenly, and then break up caking Rice group, promotes the uniformity of whole pot rice water suction and heating.
Not it is to be understood that rice amount number for bumping roll mixing power requirement different, rice amount is more, in order to stir The mixing power of the rolling needed for meter Shui is bigger, and rice amount is less, then less in order to stir rolling mixing power needed for meter Shui, application People is it has surprisingly been found that pass through to change bumping temperature TBumpingAnd/or bumping pressure PBumpingDifferent bumping mixing powers just can be produced.By This, can be carried out rational bumping pressure release and control, thus reaching the optimal effect that boils for the difference of the rice amount that boils.
Below, with cooking cavity volume as 4.0L and as a example the electric cooker of 5.0L, root is introduced by a simple example To obtain corresponding bumping temperature T according to amount V treating cooked foodBumpingMethod.Those skilled in the art are reading following skill It is clear that it can be deduced that other obtain corresponding bumping temperature T according to amount V treating cooked food after art schemeBumpingExample, with And corresponding bumping pressure P is obtained according to amount V treating cooked foodBumpingMethod.
When judging rice amount for a large amount of states, for example:Rice amount V>During 900g (6 person-portion), the stirring tumbling force now needing is Greatly, set TBumping=T, that is, bumping pressure reach pressure limiting valve 11 restriction default boiling temperature T when just carry out pressure release bumping, thus Produced the rolling mixing power of maximum.
When judging rice amount for middle amount state, for example:300g (2 person-portion)<During rice amount V≤900g (6 person-portion), now need Stirring tumbling force is medium, sets TBumping=T- Δ T1, that is, the also poor Δ T1 temperature gap of bumping pressure just reach pressure limiting valve 11 restriction Just carry out pressure release bumping, thus being produced moderate rolling mixing power during default boiling temperature T.Wherein, Δ T1 can for 1~ 3 DEG C, such as 1 DEG C, 2 DEG C or 3 DEG C etc..
