Description
Technical field
The present invention relates to pressure cooker and its control method field, more particularly to a kind of electric pressure cooking saucepan boiling point determination methods and
Perform the electric pressure cooking saucepan of the boiling point determination methods.
Background technology
Electric pressure cooking saucepan is a kind of conventional electrical equipment, for the work such as cook, cook congee.The boiling of institute's boiling article in electric pressure cooking saucepan
Point is relevant with height above sea level, causes boiling point during the difference of place to use to be possible to different.
In order to prevent overvoltage, most of electric pressure cooking saucepan is that increase detects device to identify pressure at present, such as passes through elasticity
Return unit, dry-reed tube component and control circuit identify the size of pressure.The defects of structure, is the increase in electric pressure cooker structure
Complexity, improve cost；Spare and accessory parts cross the probability at most damaged and become big, cause the overall service life of electric pressure cooking saucepan to become
It is short.
The content of the invention
It is an object of the invention to propose that one kind need not change existing electric pressure cooker structure, without the extra detection dress of increase
The electric pressure cooking saucepan boiling point determination methods put.
Another object of the present invention is to propose a kind of anti-over-pressed more preferable electric pressure cooking saucepan of effect.
For up to this purpose, on the one hand, the present invention uses following technical scheme：
A kind of electric pressure cooking saucepan boiling point determination methods, the determination methods are in design temperature [T0, T1] in record per once
The ratio between duration and preceding duration once M1, obtain maximum ratio MD；In kettle temperature more than T1Persistently record afterwards each
The ratio between the duration of degree and preceding duration once M2, as discovery M2＞ MDWhen judge electric pressure cooking saucepan reach boiling point；Wherein,
Design temperature [the T0, T1] to prejudge at a simmer temperature range, when kettle temperature is in the design temperature [T0, T1] Nei Shibi
Surely it is not up to boiling point.
Particularly, the design temperature [T0, T1] both ends threshold value changed according to height above sea level.
Further, when height above sea level is less than 2000 meters, the design temperature is [80 DEG C, 92 DEG C]；When height above sea level is optionally greater than 2000
The design temperature is [70 DEG C, 80 DEG C] during rice.
Particularly, the determination methods comprise the steps：
Step S1, electric pressure cooking saucepan performs conventional cooking procedure, when kettle temperature reaches T0After start perform boiling point judge；
Step S2, the duration T of control device start recording current temperature valueCurrently；
Step S3, described control device records the duration T of a temperature valueIt is next, M is calculated1=TIt is next/TCurrently；
Step S4, judge whether next temperature value is more than or equal to T1, it is to go to step S5, otherwise goes to step S2；
Step S5, in the M recorded1Maximum ratio M is found in valueD；
Step S6, control device continues to record the duration T of current temperature valueCurrentlyWith the duration of next temperature value
TIt is next, M is calculated2=TIt is next/TCurrently；
Step S7, M is judged2Whether maximum ratio M is more thanD, it is then to judge that electric pressure cooking saucepan reaches boiling point, otherwise goes to step
S6。
Particularly, step S6.1 is also included after step S6 and before step S7：Whether judge current temperature value
More than or equal to super boiling temperature T3, be the default value for using control device to provide for boiling point, terminate boiling point judge；Otherwise step is gone to
Rapid S7；The super boiling temperature T3Temperature value seethed with excitement to determine when being issued to the temperature value according to any altitude situations.
Further, the super boiling temperature T3For 101 DEG C.
Particularly, in step s3, T can not still be exceeded after kettle temperature value continues setting time L1Shi Caiyong control dresses
It is boiling point to put the default value provided.
Particularly, step S0 is also included before step S1：Judge whether to have found boiling point, be that then electric pressure cooking saucepan performs often
Cooking procedure is advised, otherwise goes to step S1.
On the other hand, the present invention uses following technical scheme：
A kind of electric pressure cooking saucepan, including temperature-sensitive bag and control device, the control device include timing module, computing module and
Comparing module, wherein, timing module is used for the duration T for measuring current temperature valueCurrentlyWith the duration of next temperature value
TIt is next；Computing module, for M to be calculated1=TIt is next/TCurrentlyAnd M2=TIt is next/TCurrently；Comparing module, for judging next temperature value
Whether T is more than or equal to1, and for judging M2Whether maximum ratio M is more thanD。
Electric pressure cooking saucepan boiling point determination methods of the present invention be based on be connected inside and outside pressure cooker when temperature can maintain it is a certain
This principle of temperature spot, boiling point is confirmed by recording, more often rising the time once, without changing existing electric pressure cooking saucepan
Structure, extra detection device need not be increased, using more convenient, cost is low, boiling point accuracy of judgement.
Electric pressure cooking saucepan of the present invention performs above-mentioned boiling point determination methods, and it is more accurate that boiling point judges, anti-over-pressed effect is more preferable.
Brief description of the drawings
Fig. 1 is the flow chart for the electric pressure cooking saucepan boiling point determination methods that the preferred embodiment of the present invention provides.
Embodiment
Further illustrate technical scheme below in conjunction with the accompanying drawings and by embodiment.

Value can not still exceed T after continuing setting time L1The default value that Shi Caiyong control devices provide is boiling point, setting time L and/
Or default value is to be preset in control device or user when boiling point can be product export voluntarily to determine.
Step S4, judge whether next temperature value is more than or equal to T1, it is to go to step S5, otherwise goes to step S2.When
Kettle temperature value is more than or equal to T1Start to perform the next stage of this boiling point determination methods afterwards.
Step S5, in the M recorded1Maximum ratio M is found in valueD, this maximum ratio MDAs the benchmark subsequently judged.
Step S6, conventional cooking procedure is continuously carried out, continues to record the duration of current temperature value with timed unit
TCurrentlyWith the duration T of next temperature valueIt is next, M is calculated2=TIt is next/TCurrently。
Step S6.1, judge whether current temperature value is more than or equal to super boiling temperature T3, then provided using control device
Default value is boiling point, terminates boiling point determining program；Otherwise step S7 is gone to.That is, when kettle temperature is more than or equal to super boiling temperature T3
But when not being determined arrival boiling point yet, the default value that control device provides is used as boiling point；Super boiling temperature T3Temperature value according to
Seethed with excitement when any altitude situations are issued to the temperature value to determine.Preferably, boiling temperature T is surpassed3For 101 DEG C.
Step S7, M is judged2Whether maximum ratio M is more thanD, it is then to judge that electric pressure cooking saucepan reaches boiling point, otherwise goes to step
S6。
