Pressure cooking appliance in the present embodiment includes three kinds of decompression modes, respectively exhaust decompression, water cooling decompression and wind
Cold decompression, database further include at least two in exhaust decompression, water cooling decompression and air-cooled decompression, three kinds are further included with database
For cooking food amount, two kinds of decompression modes, database is as shown in the table：
As seen from the above table, the length in the decompression section in the present embodiment is 10Kpa, by entire buck stage in a manner of descending
The 10 decompression sections formed are divided, each section that is depressured is corresponding with a decompression duration, and corresponding to same decompression section
Decompression duration further includes there are many second decompression duration, the second decompression duration while with being depressured both mode and cooking food amount phase
Matching, that is, in the case where being depressured section and determining, the second decompression duration is common by both decompression mode and cooking food amount
It determines, such as：When determining that current pressure values are in the decompression section of 100Kpa~90Kpa according to database, if control unit obtains
Current decompression mode is taken to be depressured for exhaust, cooking food amount is M1, then a length of T during the second decompressionP1；If current decompression side
Formula for exhaust be depressured, cooking food amount be M2 when, then second decompression when a length of TP2；If current decompression mode is depressured for exhaust,
Cooking food amount be M3 when, then second decompression when a length of TP3；If current decompression mode is depressured for water cooling, cooking food amount is
During M1, then second decompression when a length of TP1*；If current decompression mode is depressured for water cooling, when cooking food amount is M2, then second drops
A length of T during pressureP2*；If current decompression mode be water cooling decompression, cooking food amount be M3 when, then second decompression when a length of TP3*；
It follows that when control unit determines current pressure values after section is depressured, eaten further according to current cooking method and culinary art
Object amount is the second decompression duration that can determine corresponding to current decompression section, then the second decompression duration and less than the depressor area
Between all decompression sections corresponding to second decompression duration add up acquisition decompression remaining time.
Will be exemplified below control unit in the present embodiment is how to obtain decompression remaining time：If current pressure
Decompression mode is depressured for exhaust used by cooking apparatus, and cooking food amount is M2, and control unit determines to work as according to database
Decompression section is 70Kpa~＞ 60Kpa where preceding pressure value, then a length of T during corresponding second decompressionP22, control unit at this time
The decompression remaining time T of acquisitionP is total=TP22+TP23+TP24+TP25+TP26+TP27+TP28；If current pressure cooking appliance institute
The decompression mode used is depressured for exhaust, and cooking food amount is M3, and control unit determines current pressure values institute according to database
Section is being depressured as 50Kpa~＞ 40Kpa, then a length of T during corresponding second decompressionP34, control unit is according to the decompression at this time
Decompression remaining time T acquired in sectionP is total=TP34+TP35+TP36+TP37+TP38。
Preferably, the database in the present embodiment is further included there are one 98 DEG C of section 0Kpa~＞ of cooling, to avoid user
It uncaps and scalds when more than 98 DEG C, by setting the cooling section that can further extend remaining dip time, to ensure to use
It uncaps after the completion of decompression without burn hazard occurs at family.The cooling section is corresponding with multiple second decompression durations, the second drop
Pressure duration matches simultaneously with both decompression mode and cooking food amount.
Due to being provided with cooling section, needed when calculating and being depressured remaining time by the corresponding to the cooling section
Including two decompression duration calculations, if specifically, decompression mode is is vented decompression, culinary art used by current pressure cooking appliance
Quantity of food is M2, and control unit decompression section according to where database determines current pressure values is 70Kpa~＞ 60Kpa, this
When control unit obtain decompression remaining time TP is total=TP22+TP23+TP24+TP25+TP26+TP27+TP28+TP29；It is if current
Pressure cooking appliance used by decompression mode be depressured for exhaust, cooking food amount is M3, and control unit is according to database
Decompression section is 50Kpa~＞ 40Kpa where determining current pressure values, and control unit is according to acquired in the decompression section at this time
It is depressured remaining time TP is total=TP34+TP35+TP36+TP37+TP38+TP39。
It should be noted that after pressure drops to 0Kpa, control unit detects current according to tip temperature sensor 4
When temperature value is more than 98 DEG C, then the decompression residual time length T that obtainsP is totalIt is corresponding to be currently depressured under mode and cooking food amount
Second decompression duration, example：Current decompression mode be water cooling decompression, cooking food amount be M2, then the decompression remaining time obtained
TP is totalFor TP29*.If control unit detects that current temperature value is less than or equal to 98 DEG C according to tip temperature sensor 4, sentence
Disconnected buck stage is completed, and control unit control pressure cooking apparatus enters holding stage, and user is prompted to be depressured and is completed.
It should be noted that in buck stage, if after the decompression mode of control unit acquisition pressure cooking appliance changes, control
Unit processed reacquires the second decompression duration according to current pressure value, cooking food amount and current decompression mode, is obtained with this
Take decompression remaining time.Example：When cooking food amount is M2, the decompression section corresponding to current pressure values is 90Kpa~＞
80Kpa, decompression mode are switched to water cooling by exhaust decompression and are depressured, then remaining dip time TP is totalValue by TP20+TP21+TP22+
TP23+TP24+TP25+TP26+TP27+TP28+TP29 are switched to TP20*+TP21*+TP22*+TP23*+TP24*+TP25*+TP26*+
TP27*+TP28*+TP29*.Thus, it is depressured remaining time TP is totalCan according to decompression mode change and real-time update, avoid
The phenomenon that causing decompression remaining time inaccurate due to decompression mode changes, further improves the usage experience of user.
In order to make decompression remaining time, with the progress of buck stage, real-time update, the pressure in the present embodiment are cooked
Utensil prepare food during buck stage, pressure sensor detects the pressure value of pressure cooking appliance in real time, and by pressure value
Real-time Feedback is depressured section, and according to depressor area to control unit, control unit according to where database determines pressure value in real time
Between obtain required decompression remaining time in real time, display panel carries out in real time more according to the decompression remaining time that control unit obtains
New prompting.Namely in the initial decompression stage, if control unit is depressured section where current pressure value is determined according to database
For 70Kpa~＞ 60Kpa, if cooking food amount at this time is M2, decompression mode is depressured for exhaust, the decompression remaining time of acquisition
TP is total=TP22+TP23+TP24+TP25+TP26+TP27+TP28+TP29, with the progress of buck stage, if control unit is according to number
Decompression section is 60Kpa~＞ 50Kpa where determining current pressure value according to library, is depressured mode and the constant feelings of cooking food amount
Under condition, then the decompression remaining time T that obtainsP is total=TP23+TP24+TP25+TP26+TP27+TP28+TP29, at this time display panel show
The decompression remaining time shown is switched to TP23+TP24+TP25+TP26+TP27+TP28+TP29 value, if control unit is according to data
Decompression section is 50Kpa~＞ 40Kpa where library determines current pressure value, is depressured mode and the constant situation of cooking food amount
Under, then the decompression remaining time T that obtainsP is total=TP24+TP25+TP26+TP27+TP28+TP29, the drop that display panel is shown at this time
Pressure remaining time is switched to TP24+TP25+TP26+TP27+TP28+TP29 value, and so on, so as to reach real-time update decompression
The purpose of remaining time.It follows that the control unit in the present embodiment can be according to the change of pressure value in pressure cooking appliance
