The scheme that the above embodiments of the present application provide, by adopting each working stage in culinary art, the culinary art cavity temperature of each working stage and cooking cavity internal pressure are controlled, realize electric heating cooking device in the process of cooking, automatically the running parameter of controlling each working stage that can become more meticulous, and, owing at least comprising the sharply variation of temperature value T in a cooking cavity and/or the P duty jumpy of cooking cavity internal pressure value in whole cooking process, thereby can meet the demand of the cooking technology of each working stage, thereby reached the effect that improves food mouthfeel.

For example, can carry out example explanation with the example that is sharply changed to of cooking cavity internal pressure value P: under the state having been mixed with flavouring such as cooking wine, aromatic vinegars by cooking food in electric heating cooking device, the quick variation of cooking cavity internal pressure value P can impel the food generation of being cooked to seethe, and the part smell substance of food is dissolved in outside the volatilization discharge pot in ethanol and with ethanol.Meanwhile, the lower boiling smell substance of part also becomes gaseous state, along with follow-up exhaust process is discharged to outside pot.Also it should be noted that, because the thermal response of object before the local flavors such as the amino acid in raw material, aliphatic acid can generate some flavor substances, the auxiliary materials such as spice of these flavor substances and interpolation also can play the effect that increases taste and covering smell herein.

Preferably, in the above embodiments of the present application, can control electric-heating cooking appliance and carry out exhaust at any one or more working stages, by each working stage being controlled in cooking process, carry out respectively or all exhaust action, to inspire food generation, seethe.

Also it should be noted that herein, in the embodiment of the present application, " seething " that food in cooking cavity occurs can refer to that food " boiling " in cooking cavity has produced physical state afterwards, and " boiling " state herein includes but not limited to the boiling that food occurs under boiling point state.

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

The interior temperature value T of cooking cavity that electronic control panel 14 can be controlled electric heating cooking device is increased to fast the first preset temperature value T3 in very first time section, and control cooking cavity internal pressure value P and within the second time period, be increased to the first preset pressure value P1, wherein, very first time section is normal pressure is less than very first time threshold value time period in the temperature rise period, and the second time period was normal pressure is less than the second time threshold T2 time period in the temperature rise period.

It should be noted that, the first preset temperature value T3 in the optional embodiment of above-mentioned the first can be boiling temperature herein, and the scope of very first time threshold value can be: 2-5 minute, the scope of the second time threshold can be: 2-8 minute.Thereby this optional embodiment can realize the food in cooking cavity is heated and is pressurized to a certain degree at short notice.

In the second 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, electric control system controls electric heating cooking device carries out full exhaust and continues heating with full power, wherein, the electronic control panel 14 of electric-control system can be realized temperature value and cooking cavity internal pressure value in the cooking cavity of controlling electric heating cooking device each working stage in whole cooking process by following scheme:

At electric heating cooking device, carry out in the process of full exhaust, if electronic control panel 14 detects cooking cavity internal pressure value, P drops to the second preset pressure value P2 from the first preset pressure value P1, stop full exhaust, by controlling the power of heater, make the pressure value P (for example the second preset pressure value P2) in cooking cavity be increased to the 3rd preset pressure value P3, the interior temperature value T of cooking cavity that correspondingly controls electric heating cooking device is increased to the second preset temperature value T2, wherein, the second time period is for being less than the time period of the second time threshold in heating boost phase, now, whole cooking process enters the starting point of next working stage.

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

Preferably, the Preset Time section of above-mentioned heating boost phase can be t1, and the span of this t1 can be: 2 minutes≤t1≤8 minute.The first preset pressure value can be P1, and the span of this P1 can be: 5KPA≤P1≤45KPA.The second preset pressure value can be P2, and the span of this P2 can be: 1.325KPA≤P2≤9KPA.The 3rd preset pressure value can be P3, and the span of this P3 can be: 8KPA≤P3≤68KPA.

Hence one can see that, in the above-mentioned the second working stage of the application, boiling after the food in cooking cavity being pressurized to certain value by the optional embodiment of the first, cooking cavity internal pressure rising preset value (upper press signal) now detected thus determine that described electric heating cooking device enters heating boost phase, electric-control system carries out continuous heating by controlling electric heating cooking device at the heater of whole heating boost phase, and after boost signal being detected, control is opened air bleeding valve and is carried out part or full exhaust, the scheme that this heating boost phase continues heating when full exhaust can farthest be discharged peculiar smell in cooking cavity (as the chlorine in water, fishy smell in fish, the bad smells such as the smell of blood in meat).

In the process of full exhaust, pressure in cooking cavity cannot maintain on an interval, therefore, can make the force value decline in cooking cavity even sharply decline, temperature correspondingly also can reduce, in reduction of blood pressure in high-speed process, can make the food in cooking cavity form bumping,, make the large boiling of food, when cooking cavity internal pressure value P being detected and drop to the second preset pressure value P2 (P2 can be normal pressure), stop full exhaust, now exhaust finishes, it is in cooking cavity, to continue to boost that control heater heats, thereby the food in cooking cavity is continued to processing.

Need to stress: in exhaust process, also in the control of carrying out continuous heating, (exhaust is according to the difference of function herein, can be the whole exhausts of heating with full power, also can be with certain heating power row, or intermittent exhaust or even both are hocketed).

Concrete, in dish cooking process, lasting raising due to the cooking cavity temperature of electric heating cooking device, food materials can be heated to boiling from normal temperature and then carry out large exhaust, and in exhaust process continuous heating still, therefore, by a large amount of exhausts, meanwhile heat and produce large boiling, can allow food materials fully peculiar smell be discharged to (comprising chlorine in water etc.), by exhaust, take away volatility bad smell material.For example, the lower boiling smell substance of part can become gaseous state, now carries out large exhaust, can be by smell substance along with exhaust is discharged to outside pot, in addition, for example interpolation of cooking wine, can, so that part smell substance is dissolved in ethanol, also can discharge outside pot with the volatilization of ethanol.Meanwhile, because the thermal response of the flavour precursors things such as the amino acid in raw material, aliphatic acid can generate some flavor substances, the auxiliary materials such as spice of these flavor substances and interpolation also can play the effect that increases taste and covering smell.

In addition, the application can also provide another optional scheme to realize the method for discharging peculiar smell at removal heating boost phase: before upper pressure, under system is controlled, the electronic control panel 14 of electric-control system is controlled the food making in cooking cavity and is maintained 100 ℃ of certain temperature a period of times before,, before the food in cooking cavity does not arrive boiling point, by controlling exhaust apparatus, discharge a certain amount of gas simultaneously.This control method, key point is to give off how many gas flows at heating boost phase, specific implementation can large capacity of unit interval be discharged a certain amount of gas fast, can be also that unit interval float tolerance gives off the gas of this amount with the long period.This exhaust process, food produces either large or small seething, and peculiar smell is discharged, but temperature value in this process cooking cavity remains unchanged.

Also it should be noted that herein, before heating boost phase control exhaust apparatus carries out exhaust action, the upper and lower pressure balance of liquid level in pot, when exhaust occurs, pressure decreased in cooking cavity on liquid level, now, the upper and lower pressure balance of liquid level is broken, original steam bubble in liquid rises and causes that liquid presents fluidized state, and the boiling point of liquid declines because of pressure decreased, cause that vaporizing liquid accelerates, and continuous heating can further accelerate gasification during exhaust, on the whole, in pot, food presents and seethes rolling condition.Further, unit interval capacity is larger, and pressure changes quicker, and boiling degree Shaoxing opera is strong, and this process is as heat tracing, and boiling degree is aggravated again, and severe degree is directly proportional to heating power size.

In above-mentioned the second working stage, electronic control panel 14 can be realized temperature value and cooking cavity internal pressure value in the cooking cavity of controlling electric heating cooking device each working stage in whole cooking process by following another scheme: record the evacuation time that electric heating cooking device carries out full exhaust, after evacuation time reaches scheduled duration, stop full exhaust, and the cooking cavity internal pressure value of record while stopping exhaust, and the cooking cavity internal pressure value of controlling while stopping exhaust being increased to the 3rd preset pressure value P3, and the interior temperature value T of the cooking cavity of controlling electric heating cooking device is increased to the second preset temperature value T2 within the second time period.

Further it should be noted that, the second preset temperature value T2 in the optional embodiment of above-mentioned the second can be higher than boiling temperature, and the scope of the 3rd time threshold can be 3-8 minute.Thereby this optional embodiment can realize after the food in cooking cavity is discharged to peculiar smell, need to continue food in pot to heat pressurization.

In the third working stage in the above embodiments of the present application two, when electric heating cooking device receives pressurize signal, electric heating cooking device enters the pressure dynamic equilibrium stage (being packing stage), pressure in the pressure dynamic equilibrium stage (being packing stage) changes the period, electric control system controls electric heating cooking device arranges control exhaust apparatus according to the default exhaust of selected food and carries out full exhaust or intermittently exhaust, wherein, in the cooking cavity of control electric heating cooking device each working stage in whole cooking process of realizing, the step of temperature value and cooking cavity internal pressure value can comprise following a kind of optional embodiment:

Control cooking cavity internal pressure value P and during pressure dynamic equilibrium stage (being packing stage), keep the 3rd preset pressure value P3, and the interior temperature value T of cooking cavity that controls electric heating cooking device keeps the second preset temperature value T2 within the pressure dynamic equilibrium stage (being packing stage).It should be noted that, pressure dynamic equilibrium stage (being packing stage), the 3rd preset pressure value P3 can fluctuate up and down along with the variation of exhaust and temperature herein.

Preferably, at above-mentioned working stage, be pressure dynamic equilibrium in the situation that of the stage, in Preset Time section, electric control system controls exhaust apparatus is carried out intermittent exhaust action to preset the release.

In the first possibility, in the release of exhaust apparatus, be to open to close 10 seconds for 1 second.In the second possibility, in the release of exhaust apparatus, be to open within 0.1 second, to close to open for 0.7 second to close 30 seconds for 0.2 second.

Temperature value and cooking cavity internal pressure value in the cooking cavity of control electric heating cooking device each working stage in whole cooking process that wherein, above-mentioned electronic control panel 14 can be realized by following scheme:

The electronic control panel 14 control cooking cavity internal pressure value P of electric-control system occur to drop to minor fluctuations preset pressure value P31 from the 3rd preset pressure value P3 and go up to the variation of the 3rd preset pressure value P3 (in the pressure dynamic equilibrium stage, above-mentioned the 3rd preset pressure value P3 has minor fluctuations) again within the pressure dynamic equilibrium stage (being packing stage).

In above-mentioned the third working stage of the application, after by the second, optional embodiment continues to be pressurized to certain value by the food in cooking cavity, control current temperature value and the force value of maintenance in cooking cavity, and in this process, carry out exhaust control, preferably can adopt the intermittently mode of exhaust.

Therefore,, after heating boost phase reaches default dwell pressure, enter the pressure dynamic equilibrium stage (being packing stage).In the pressure dynamic equilibrium stage (being packing stage), can initiatively determine heating with full power and all exhaust (also can carry out exhaust with certain heating power) or intermittent exhaust or not exhausts according to the selection of the characteristic of raw material and cooking function.The time of this exhaust is also flexible and changeable, can carry out exhaust or in the later stage exhaust in pressure dynamic equilibrium stage (being packing stage) etc. whole pressure dynamic equilibrium stage (being packing stage).

It should be noted that herein, pressure dynamic equilibrium stage (being packing stage), by controlled pressure generation minor variations while initiative exhaust, realizing food has the little of discontinuity by a small margin to seethe in the whole pressure dynamic equilibrium stage (being packing stage), or bring a large boiling to roll by initiative exhaust, because food is under the state that seethes that pressure changes and exhaust action produces, separate out of local flavor amino acid is free in soup more, the food rendering palatable for receipts juice or stewing stewed food, part amino acid is separated out rear answering and is entered again in food, therefore make taste of food more delicious tasty.Thus, above-mentioned the third optional example implementation, by revising pressure, temperature, time, make protein degradation more rationally (protein degradation number, local flavor to food has material impact), to realize food, carry freshly, can make condiment etc. better tasty, also make food materials mutually clash into, better discharge 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 step-down signal, electric heating cooking device enters exhaust buck stage, electric control system controls electric heating cooking device carries out the duty of full exhaust continuous heating, temperature value and cooking cavity internal pressure value in the cooking cavity of control electric heating cooking device each working stage in whole cooking process that wherein, the electronic control panel 14 of electric-control system is realized by following scheme:

In the situation that electronic control panel 14 detects cooking cavity internal pressure value P and drops to the 4th preset pressure value P4, control cooking cavity internal pressure value P and within the 4th time period, be increased to the 5th preset pressure value P5, and the interior temperature value T of the cooking cavity of controlling electric heating cooking device is increased to the 3rd preset temperature value T3 within the 4th time period, wherein, the 4th time period was in exhaust buck stage, to be less than the time period of the 4th time threshold.

In above-mentioned the 4th kind of working stage of the application, thereby step-down signal triggering electric heating cooking device detected and enter exhaust buck stage, when reaching default step-down working stage, electric control system controls electric heating cooking device enters exhaust buck stage, now, electric-control system is carried out exhaust and is controlled heater and carry out continuous heating by the exhaust action of controlling the exhaust apparatus of electric heating cooking device and defining by the defined culinary art Curves of selected food, especially, when making exhaust apparatus that the very large large exhaust action of capacity occur at short notice, make the food in cooking cavity carry out the large exhaust of certain hour, continue to add thermal control simultaneously, thereby make bumping, the large boiling of food makes the food in cooking cavity complete the receipts juice that anhydrates, can make more moisture evaporation fall, realize the effect of condensed soup juice, because soup juice is dense, can increase local flavor amount of substance on meat, promote mouthfeel, and it is good to reach the effective food mouthfeel of culinary art.The exhaust in this stage can be total power exhaust.

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

It should be noted that, in exhaust buck stage, the first preset pressure value can be P3 herein, and the second preset pressure value can be P4, and the 3rd preset pressure value can be P5.Preset Time section can be t3, and preferably, the span of t3 can be: 2 minutes≤t3≤11 minute.

Preferably, when now the first preset pressure value is P3, the span of this P3 can be: 8KPA≤P3≤68KPA.Now the second preset pressure value is P4, and the span of this P4 can be: 5KPA≤P4≤13KPA.Now the 3rd preset pressure value is P5, and the span of P5 can be: 8KPA≤P5≤40KPA.

In the process of full exhaust, pressure in cooking cavity cannot maintain on an interval, therefore, can make the force value in cooking cavity sharply decline, temperature also can reduce, and cooking cavity internal pressure value P being detected, from the first preset pressure value, can be that P3 is while being reduced to the second preset pressure value P4 (P4 can be normal pressure), stop full exhaust, now exhaust finishes, and controls and continues to boost and continuous heating, thereby the food in cooking cavity is continued to processing.

Concrete, because food can seethe because pressure changes to produce seethe especially acutely, be conducive to that local flavor in animal food materials is especially amino acid whose separates out and in free state.In exhaust buck stage, control and sharply decline by the force value in the cooking cavity of large exhaust, realized by adjusting the exhaust buck stage of last culinary art and carried out exhaust receipts juice, can make soup juice dense, increase local flavor amount of substance on meat.For example, some water miscible flavor components in cooking process, are taste amino acid and can transfer in a large number in soup juice such as what protein degradation formed, if steam discharge is received juice, can cause the local flavor of meat not good enough.By exhaust, can reduce moisture, increase solid content, stick to the surface and the inside that is penetrated into meat of meat, make meat entrance more lubricated, the taste of meat is stronger.So it is better that the mouthfeel of meat will become.

In above-mentioned the 4th kind of working stage, the electronic control panel 14 of electric-control system can also be realized temperature value and cooking cavity internal pressure value in the cooking cavity of controlling electric heating cooking device each working stage in whole cooking process by following another scheme: record the evacuation time that electric heating cooking device carries out full exhaust, after evacuation time reaches scheduled duration, stop full exhaust, and the cooking cavity internal pressure value of record while stopping exhaust, and the cooking cavity internal pressure value of controlling while stopping exhaust being increased to the 5th preset pressure value within the 4th time period, and control simultaneously electric heating cooking device heater by the power that presets of the culinary art curve of selected food, carry out work.

The interior temperature value T of cooking cavity that controls electric heating cooking device is increased to the 3rd preset temperature value T3 within the 4th time period, and wherein, the 4th time period was in exhaust buck stage, to be less than the time period of the 4th time threshold.

Further it should be noted that, the second preset temperature value T2 in the optional embodiment of above-mentioned the second can be higher than boiling temperature, and the scope of the 3rd time threshold can be: 3-8 minute.Thereby this optional embodiment can realize after the food in cooking cavity is discharged to peculiar smell, need to continue food in pot to heat pressurization.

In the 5th kind of optional working stage in the above embodiments of the present application two, when electric heating cooking device enters exhaust while uncapping the stage, control electric heating cooking device and carry out full exhaust, temperature value and cooking cavity internal pressure value in the cooking cavity of control electric heating cooking device each working stage in whole cooking process that the electronic control panel 14 of electric-control system can be realized by following scheme:
