Description
Technical field
The present invention relates to a kind of SMART COOKWARE more particularly to a kind of intelligent pressure regulating pot and its control methods.
Background technique
For boiling point by effects of air pressure, air pressure is higher, and boiling point is higher.The boiling point of water at normal atmospheric pressure is 100 DEG C, in Gao Hai
It rises sheer from level ground area, air pressure is low, and boiling point is also below 100 DEG C, for example the boiling point of Qinghai-Tibet water only has 60-80 DEG C, if air pressure is greater than 1
When standard atmospheric pressure, water can will just boil at temperatures above 100.degree.c.Pressure cooker is namely based on the principle.Pressure cooker can more hold
Easily cooked food, but it also be easy to cause more nutrition losses simultaneously, the food mouthfeel being cooked under different boiling points is also different.
By taking hand-made noodles with beef, Lanzhou style as an example, the senior hand-pulled noodles master worker in same position is just done with same cooker and food materials, including water in other places
That distinctive taste of Lanzhou is not come out, many strangers to Lanzhou taste beef noodle and are profuse in praise.To find out its cause, Lanzhou is worked as
The boiling point of ground water is 95 DEG C, beef can be cooked under this boiling point and nutrition loss, moreover it is possible to by the essence in beef
China incorporates in soup, so that beef noodle hundred is eaten and do not minded.But existing pressure cooker can only increase air pressure in pot, reach boiling point in pot
More than the boiling point under to local air pressure, and pressure in pot cannot be reduced, therefore culinary art boiling point can not be made to exist in the area of low altitude area
95 DEG C or meet the requirement of specific boiling point culinary art lower than other temperature of local boiling point.Not only hand-made noodles with beef, Lanzhou style, very
Mostly characteristic snack cannot walk out locality genuinely elsewhere, and an important reason is exactly height above sea level difference, boil in other words
Point is different.
Summary of the invention
It is an object of the invention to avoid the deficiencies in the prior art, a kind of intelligent pressure regulating pot and its control method are provided.Base

Specific embodiment
The principle and features of the present invention will be described below with reference to the accompanying drawings, and the given examples are served only to explain the present invention, and
It is non-to be used to limit the scope of the invention.
Embodiment 1, intelligent pressure regulating pot and its control method.In Shanghai, boiling point is 100 DEG C, in order to which beef noodle is made orchid
The peculiar taste in state, it is a critically important factor that culinary art beef noodle soup is carried out under 95 DEG C of boiling points.
Beef, condiment and water etc. are put into pot in proportion, tightening pot cover is to guarantee leakproofness, it is ensured that in negative pressure or just
Pressure does not leak.
Power supply is powered and opens system switching, sets 95 DEG C of target boiling point by operation button, display display setting
95 DEG C of boiling point, start control system, heating method is open firing, starts to cook, and pressure transducer is used in pot, just starts pot
Interior temperature is lower than 95 DEG C, and the temperature that sensor detects passes controller back and 95 DEG C of setting are compared, lower than target boiling point,
Controller controls solenoid valve, vacuum pump (vacuum pump selects frequency modulation motor vacuum pump) power-off, and solenoid valve is closed, and frequency modulation motor is true
Empty air pump inoperative, at this time since pot seals and constantly heating, kettle temperature constantly increase, at a time, temperature reaches and omits
Micro- to be higher than 95 DEG C, 95 DEG C of the temperature information from sensor that controller receives at this time and setting are compared, and are higher than setting
Temperature, the solenoid valve of controller control at this time, frequency modulation motor vacuum pump are powered, and solenoid valve is opened, and frequency modulation motor vacuum pump is started to work,
Pressure in pot is reduced, and then reduces water boiling point or cooking temp in pot, when controller is received again by temperature signal lower than 95 DEG C
When, it controls solenoid valve and the power-off of frequency modulation motor vacuum pump, solenoid valve closes, frequency modulation vacuum pump stops working.Material is thus formed
Dynamic equilibrium so that kettle temperature be maintained at 95 DEG C (temperature is the water boiling point in current pot under pressure) it is small range of up and down
Fluctuation is to realize with the purpose of 95 DEG C of boiling point Boiled beef.
Culinary art finishes, and uncaps the process for taking out food as ordinary high pressure pot, cannot uncap at once, to prevent endangering
Danger.
Embodiment 2, in Chongqing, boiling point is about 98 DEG C, boils certain Chinese medicine, and pot body selection is suitble to the material of tanning Chinese medicine,
For example selection makes material or ceramic material of traditional casserole etc., boils the best mode of this kind of Chinese medicine are as follows: endure at 105 DEG C
Then system 10 minutes boils 30 minutes at 90 DEG C.Tanning time and temperature, selection electricity are inputted according to above-mentioned data in the controller
Hot mode is heated, and heating is controlled by single-chip microcontroller.Stablize from starting kettle temperature at 105 DEG C, process and 1 phase of embodiment
Together, kettle temperature stabilization is kept 10 minutes after 103 DEG C, is adjusted the temperature to 90 DEG C by the adjusting of controller again later and is protected
It holds 30 minutes, powers off later, tanning is completed.
