Preferably, in the above embodiments of the present application, electric-heating cooking appliance can be controlled in any one or more work ranks Section is exhausted, and action is exhausted respectively or all by controlling each working stage in cooking process, to inspire food Object generation is seethed.

Herein it should also be noted that, in the embodiment of the present application, " seething " that the food in cooking cavity occurs can be Refer to food and produce physical state after " boiling " in cooking cavity, " boiling " state herein includes but not limited to that food is boiling The boiling occurred under dotted state.

In the first working stage in the above embodiments of the present application, when electric heating cooking device is in the normal pressure temperature rise period When, the control electric heating cooking device that above-mentioned electronic control panel 14 can be realized by following scheme is each in entire cooking process Pressure value in temperature value and cooking cavity in the cooking cavity of working stage：

Electronic control panel 14 can control temperature value T in the cooking cavity of electric heating cooking device and quickly be increased in first time period To the first preset temperature value T3, and controls pressure value P in cooking cavity and is increased to the first preset pressure value P1 in second time period, Wherein, first time period is to be less than the period of first time threshold in the normal pressure temperature rise period, and second time period heats up for normal pressure It is less than the period of second time threshold T2 in stage.

Herein it should be noted that the first preset temperature value T3 in the first above-mentioned alternative embodiment can be boiling temperature Degree, the range of first time threshold can be：2-5 minutes, the range of second time threshold can be：2-8 minutes.To be somebody's turn to do Alternative embodiment may be implemented that the food in cooking cavity is carried out to heating pressurization in a short time to a certain extent.

In second of working stage in the above embodiments of the present application, when electric heating cooking device receives upper pressure signal, Electric heating cooking device enters heating boost phase, and electric control system controls electric heating cooking device is vented and is continued heating with full power entirely, Wherein, the electronic control panel 14 of electric-control system can realize control electric heating cooking device in entire cooking process by following scheme In each working stage cooking cavity in pressure value in temperature value and cooking cavity：

During electric heating cooking device be vented entirely, if electronic control panel 14 detects pressure value P in cooking cavity Drop to the second preset pressure value P2 from the first preset pressure value P1, stop full exhaust, the power by controlling heating device makes Pressure value P (such as second preset pressure value P2) in cooking cavity is increased to third preset pressure value P3, correspondingly controls electric heating Temperature value T is increased to the second preset temperature value T2 in the cooking cavity of cooking pot, wherein second time period is in heating boost phase Less than the period of second time threshold, at this point, entire cooking process enters the starting point in subsequent work stage.

Preferably, above-mentioned heating boost phase, the difference between the first preset pressure value P1 and the second preset pressure value P2 The numberical range of △ P1 can be：3kpa≤△P1≤40kpa.

Preferably, the preset time period of above-mentioned heating boost phase can be t1, and the value range of the t1 can be：2 points Clock≤t1≤8 minute.First preset pressure value can be P1, and the value range of the P1 can be：5KPA≤P1≤45KPA.The Two preset pressure values can be P2, and the value range of the P2 can be：1.325KPA≤P2≤9KPA.Third preset pressure value can Think P3, the value range of the P3 can be：8KPA≤P3≤68KPA.

It follows that in above-mentioned second of the working stage of the application, will be in cooking cavity by the first alternative embodiment Heat foods be pressurized to after certain value and boil, detect at this time culinary art cavity pressure rise preset value (i.e. upper to press signal) from And determining that the electric heating cooking device enters heating boost phase, electric-control system is by controlling electric heating cooking device in entire heating boosting The heating device in stage carries out continuous heating, and after detecting boost signal, control open air bleeding valve carry out part or Full exhaust, the scheme that this heating boost phase continues heating when being vented entirely can farthest be discharged different in cooking cavity Taste (chlorine in such as water, the bad smells such as the fishy smell in fish, the smell of blood in meat).

During full exhaust, the pressure in cooking cavity is unable to maintain that on a section, therefore, can make cooking cavity Interior pressure value, which declines, even drastically to be declined, and temperature correspondingly can also reduce, and can make in cooking cavity during reduction of blood pressure in high-speed Food forms bumping, that is, so that the big boiling of food, is detecting that pressure value P drops to the second preset pressure value P2 in cooking cavity When (P2 can be normal pressure), stop full exhaust, exhaust at this time terminates, and control heating devices heat is to be in cooking cavity after of continuing rising Pressure, to continue to process to the food in cooking cavity.

Need to stress herein is：Also in the control for carrying out continuous heating, (exhaust is according to function in exhaust process Difference, can be that heating with full power is all vented, can also arrange with certain heating power, or intermittent be vented even two Person is alternately).

Specifically, during dish cooking, due to electric heating cooking device cooking cavity temperature it is constantly improve, can will eat Material is heated to boiling from room temperature and is then vented greatly, and the still continuous heating in exhaust process, therefore, by a large amount of Exhaust at the same time heating generates big boiling, can allow food materials that peculiar smell is fully discharged (including chlorine etc. in water), that is, pass through row Gas takes away volatility bad smell substance.For example, the low-boiling smell substance in part can become gaseous state, it is vented greatly at this time, Smell substance can be discharged to exhaust outside pot, in addition, the addition of such as cooking wine, can make part smell substance be dissolved in In ethyl alcohol, it can also be discharged outside pot with the volatilization of ethyl alcohol.Meanwhile because of Flavor Prccursors such as amino acid, aliphatic acid in raw material Thermal response produce some flavors, the auxiliary materials such as spice of these flavors and addition can also play flavour enhancing and covering smell Effect.

It is arranged in removal heating boost phase in addition, the application can also provide another optional scheme to realize Go out the method for peculiar smell：Before upper pressure, under system control, the control of electronic control panel 14 of electric-control system makes in cooking cavity Food maintains certain temperature before 100 DEG C for a period of time, i.e., before the food in cooking cavity does not reach boiling point, leads to simultaneously It crosses control exhaust apparatus and a certain amount of gas is discharged.This control method, key point are that how much gas given off in heating boost phase The scale of construction, specific implementation, can quickly be discharged a certain amount of gas with unit interval big capacity, can also be unit interval small capacity The gas of this amount is given off with the long period.This exhaust process, food generate it is either large or small seethe, peculiar smell is moved out, but Temperature value in this process cooking cavity remains unchanged.

Herein it should also be noted that, before action is exhausted in heating boost phase control exhaust apparatus, cooking pot Pressure balance above and below interior liquid level, when being vented generation, the pressure reduction in cooking cavity on liquid level, at this point, above and below liquid level Pressure balance is broken, and original steam bubble in liquid rises and causes liquid that fluidized state is presented, also, the boiling point of liquid is because of pressure Power reduces and declines, and continuous heating can further speed up gasification when causing liquid vaporization to accelerate, and being vented, whole On, food presents and seethes rolling condition in pot.Further, unit interval capacity is bigger, and pressure change is quicker, journey of boiling Degree is more violent, this process such as heat tracing, boiling degree is aggravated again, and severe degree is directly proportional to heating power size.

In above-mentioned second of working stage, electronic control panel 14 can realize control by another following scheme Electric heating cooking device pressure value in temperature value and cooking cavity in the cooking cavity of each working stage in entire cooking process：Record electricity The evacuation time that heat cooking device is vented entirely stops full exhaust, and record stopping after evacuation time reaches scheduled duration Pressure value in cooking cavity when exhaust, and control pressure value in cooking cavity when stopping exhaust and be increased to third preset pressure value P3, and control temperature value T in the cooking cavity of electric heating cooking device and be increased to the second preset temperature value T2 in second time period.

Explanation is needed further exist for, the second preset temperature value T2 in above-mentioned second of alternative embodiment can be above The range of boiling temperature, third time threshold can be 3-8 minutes.To which, the alternative embodiment may be implemented by cooking cavity After interior food release peculiar smell, need to continue to carry out heating pressurization to food in pot.

In the third working stage in the above embodiments of the present application two, when electric heating cooking device receives pressurize signal When, electric heating cooking device enters Pressure behaviour equilibrium stage (i.e. packing stage), at Pressure behaviour equilibrium stage (i.e. packing stage) The pressure change period, electric control system controls electric heating cooking device according to the default exhaust of selected food be arranged control exhaust apparatus into The full exhaust of row or interval be vented, wherein the control electric heating cooking device of realization each working stage in entire cooking process is cooked The step of pressure value in cavity temperature value and cooking cavity of preparing food may include a kind of following optional embodiment：

It controls pressure value P in cooking cavity and keeps third preset pressure value in Pressure behaviour equilibrium stage (i.e. packing stage) P3, and control temperature value T in the cooking cavity of electric heating cooking device and keep second in Pressure behaviour equilibrium stage (i.e. packing stage) Preset temperature value T2.Herein it should be noted that at Pressure behaviour equilibrium stage (i.e. packing stage), third preset pressure value P3 It can up and down be fluctuated with exhaust and the variation of temperature.

Preferably, in the case where above-mentioned working stage is Pressure behaviour equilibrium stage, in preset time period, electric-control system It controls exhaust apparatus and intermittent exhaust event is executed with the default release.

It is to open 1 second to close 10 seconds in the release of exhaust apparatus in the first alternative.In second of alternative In, it is to open to close within 0.1 second to open within 0.7 second 0.2 second to close 30 seconds in the release of exhaust apparatus.

Wherein, the control electric heating cooking device that above-mentioned electronic control panel 14 can be realized by following scheme is entirely being cooked Pressure value in temperature value and cooking cavity in the cooking cavity of each working stage in the process：

Pressure value P is in Pressure behaviour equilibrium stage (i.e. pressurize rank in the control cooking cavity of electronic control panel 14 of electric-control system Section) in occur to drop to minor fluctuations preset pressure value P31 from third preset pressure value P3 and go up again to third preset pressure value The variation of P3 (i.e. in Pressure behaviour equilibrium stage, above-mentioned third preset pressure value P3 is to have minor fluctuations).

In the third above-mentioned working stage of the application, the food in cooking cavity is being continued by second of alternative embodiment It is pressurized to after certain value, keeps current temperature value and pressure value in control cooking cavity, and arranged in this process The mode of interval exhaust preferably may be used in gas control system.

Therefore, after heating boost phase reaches preset dwell pressure, into Pressure behaviour equilibrium stage (i.e. pressurize rank Section).It can actively be determined according to the characteristic of raw material and the selection of cooking function in Pressure behaviour equilibrium stage (i.e. packing stage) Heating with full power and all exhaust (can also be exhausted with certain heating power) are either intermittent to be vented or is not vented.This The time of a exhaust is also flexible and changeable, can be exhausted in entire Pressure behaviour equilibrium stage (i.e. packing stage) or In the late stage exhaust etc. of Pressure behaviour equilibrium stage (i.e. packing stage).

Herein it should be noted that at Pressure behaviour equilibrium stage (i.e. packing stage), occurred by control pressure small Initiative exhaust, realization food have discontinuity by a small margin in entire Pressure behaviour equilibrium stage (i.e. packing stage) simultaneously for variation It is small seethe, or bring a big boiling to roll by initiative exhaust, since food is in pressure change and exhaust event What is generated seethes under state, flavor amino acid is more precipitated and is free in soup, for receiving the food that renders palatable of juice or stewing stewing Food, a part of amino acid is multiple after being precipitated to be entered in food again, therefore keeps taste of food more delicious tasty.It is above-mentioned as a result, The third optional example implementation, by change pressure, temperature, the time, make protein degradation more rationally (protein degradation How much, the flavor of food is had a major impact), to realize that it is fresh that food carries, condiment etc. can be made preferably tasty, also make food materials mutual It hits, preferably discharges delicate flavour material.

In the 4th kind of working stage in the above embodiments of the present application one, when electric heating cooking device receives buck signal When, electric heating cooking device enters exhaust buck stage, and electric control system controls electric heating cooking device carries out the work of full exhaust and continuous heating Make state, wherein the control electric heating cooking device that the electronic control panel 14 of electric-control system is realized by following scheme is entirely being cooked Pressure value in temperature value and cooking cavity in the cooking cavity of each working stage during preparing food：

In the case where electronic control panel 14 detects that pressure value P drops to the 4th preset pressure value P4 in cooking cavity, control Pressure value P is increased to the 5th preset pressure value P5 within the 4th period in cooking cavity processed, and controls the culinary art of electric heating cooking device Cavity temperature value T is increased to third preset temperature value T3 within the 4th period, wherein the 4th period was exhaust buck stage Inside it is less than the period of the 4th time threshold.

In the above-mentioned 4th kind of working stage of the application, buck signal is detected to trigger electric heating cooking device and enters exhaust drop In the pressure stage, when reaching preset decompression working stage, electric control system controls electric heating cooking device enters exhaust buck stage, this When, what electric-control system was defined by controlling the exhaust apparatus of electric heating cooking device by culinary art curve defined in selected food Exhaust event evacuates and controls heating device progress continuous heating and is especially sent out in a short time when making exhaust apparatus When the prodigious big exhaust event of raw capacity so that the big exhaust for having carried out certain time to the food in cooking cavity is held simultaneously It is continuous to carry out computer heating control, to make bumping, the big boiling of food go water to receive juice so that carrying out completion to the food in cooking cavity, can make More moisture evaporations fall, and realize that the effect of concentration soup can increase the amount of flavor substance on meat, carry since soup is dense Mouthfeel is risen, and it is good to reach the culinary art good food mouthfeel of effect.The exhaust in this stage can be total power exhaust.

Preferably, when working stage is exhaust buck stage, the first preset pressure value P3 and the second preset pressure value P4 Between the numberical range of difference △ P2 be：28kpa≤△P2≤57kpa.

Herein it should be noted that in exhaust buck stage, the first preset pressure value can be P3, the second preset pressure value Can be P4, third preset pressure value can be P5.Preset time period can be t3, it is preferable that the value range of t3 can be： 2 minutes≤t3≤11 minute.

Preferably, when the first preset pressure value is P3 at this time, the value range of the P3 can be：8KPA≤P3≤68KPA. The second preset pressure value is P4 at this time, and the value range of the P4 can be：5KPA≤P4≤13KPA.Third preset pressure at this time Value is P5, and the value range of P5 can be：8KPA≤P5≤40KPA.

During full exhaust, the pressure in cooking cavity is unable to maintain that on a section, therefore, can make cooking cavity Interior pressure value drastically declines, and temperature can also reduce, and is detecting that pressure value P can be from the first preset pressure value in cooking cavity When P3 is reduced to the second preset pressure value P4 (P4 can be normal pressure), stop full exhaust, exhaust at this time terminates, and control continues to boost And continuous heating, to continue to process to the food in cooking cavity.

Specifically, since food especially can acutely be seethed because pressure change generates to seethe, be conducive to especially animal food The precipitation of flavor amino acid in material is simultaneously in free state.In the cooking cavity that exhaust buck stage control passes through big exhaust Pressure value drastically decline, realize the exhaust buck stage by adjusting finally cooking and receipts juice be exhausted, soup can be made dense Thickness increases the amount of flavor substance on meat.For example, the water-soluble flavor components of some in cooking process, such as protein degradation shape At delicious amino acid can largely be transferred in soup, if not steam discharge receive juice, the flavor of meat can be caused not good enough.It, can by exhaust Moisture is reduced, solid content is increased, the surface of meat is adhered to and penetrates into the inside of meat, meat entrance is made more to lubricate, meat Taste is stronger.So the mouthfeel of meat will become more preferable.

In above-mentioned 4th kind of working stage, the electronic control panel 14 of electric-control system can also pass through another following side Case realizes the control electric heating cooking device in entire cooking process in the cooking cavity of each working stage in temperature value and cooking cavity Pressure value：The evacuation time that record electric heating cooking device is vented entirely stops full row after evacuation time reaches scheduled duration Gas, and record stop exhaust when cooking cavity in pressure value, and control stop exhaust when cooking cavity in pressure value at the 4th Between be increased to the 5th preset pressure value in section, and control simultaneously the heating device of electric heating cooking device by selected food culinary art The presetting power of curve works.

It controls temperature value T in the cooking cavity of electric heating cooking device and is increased to third preset temperature value T3 within the 4th period, Wherein, the 4th period was to be vented the period for being less than the 4th time threshold in buck stage.

Explanation is needed further exist for, the second preset temperature value T2 in above-mentioned second of alternative embodiment can be above The range of boiling temperature, third time threshold can be：3-8 minutes.To which, the alternative embodiment may be implemented by cooking cavity After interior food release peculiar smell, need to continue to carry out heating pressurization to food in pot.

In the 5th kind of optional working stage in the above embodiments of the present application two, uncap when electric heating cooking device enters exhaust When the stage, control electric heating cooking device is vented entirely, and the electronic control panel 14 of electric-control system can be realized by following scheme Control electric heating cooking device in entire cooking process pressure value in temperature value and cooking cavity in the cooking cavity of each working stage：
