Description
Technical field
The present invention relates to a kind of cooking machine pot temperature control methods.
Background technology
Full-automatic frying machine is needed during cooking according to dispensing at temperature real-time in pot or addition condiment.And it fries
Situation is complicated in pot during dish：Local temperature and mean temperature differ, pot mouth and cooking bottom temperature differ, in pot outer surface and pot
Surface temperature is not first-class, causes to be difficult to determine actual temperature in pot and cause cooking not yet done or fried situation.
Invention content
The present invention proposes a kind of cooking machine pot temperature control method, can accurately measure, predict and control kettle temperature.
The technical proposal of the invention is realized in this way：
A kind of cooking machine pot temperature control method, which is characterized in that include the following steps：
S1, pot are 430 magnetic stainless steels of outer surface layer, the fine aluminium of middle layer, interior surface layers respectively from outside to inside
304 stainless steels, uniformly distributed electromagnetic heating coil on the outer surface layer；Pot is by integrally formed columnar pot mouth, arc-shaped
Pot in the middle part of and pot bottom composition；
S2, non-contact temperature sensor detection pot middle part and pot bottom intersection temperature,；
S3, in pot at the uniform velocity rotary course, several groups of temperature values of timing acquiring；
S4, by removing noise merging averaging and establishing temperature model, then pass through Kalman Prediction and linear regression calculation
Method obtains the temperature funtion of pot inner wall.
Preferably, in the middle part of pot and pot bottom intersection section is in oblique 45 °.
Preferably, when being oil, water, dish in pot, corresponding regression equation coefficient is different.
What the present invention generated has the beneficial effect that：The pot of the present invention rotates always, so using non-contact infrared
Temperature is measured it, and hull-skin temperature can only be measured.And the temperature that we need is a pot internal surface temperature, so having to count
Equation of linear regression and dissipated power are calculated to predict the kettle temperature of subsequent time, therefore can effectively pass through using the present invention
Pot external temperature is measured to obtain and monitor the value of pot internal surface temperature in real time.
Specific embodiment
Technical scheme of the present invention is clearly and completely described below in conjunction in the embodiment of the present invention, it is clear that institute
The embodiment of description is only part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention,
Those of ordinary skill in the art's all other embodiments obtained without making creative work, belong to this hair
The range of bright protection.
A kind of cooking machine pot temperature control method, includes the following steps：
S1, pot are 430 magnetic stainless steels of outer surface layer, the fine aluminium of middle layer, interior surface layers respectively from outside to inside
304 stainless steels, uniformly distributed electromagnetic heating coil on the outer surface layer；Pot is by integrally formed columnar pot mouth, arc-shaped
Pot in the middle part of and pot bottom composition；
S2, non-contact temperature sensor detection pot middle part and pot bottom intersection temperature,；
S3, in pot at the uniform velocity rotary course, several groups of temperature values of timing acquiring；
S4, by removing noise merging averaging and establishing temperature model, then pass through Kalman Prediction and linear regression calculation
Method obtains the temperature funtion of pot inner wall.
Three layers of kettle temperature point：Pot mouth, middle part, bottom, due to cooking be concentrated mainly on middle part layer thus we pass through it is red
Oblique 45 ° of acquisitions pot extexine temperature at external middle part and bottom margin.The purpose for the arrangement is that allow heating caused by environment temperature
Degree does not interfere infrared sensor to measure target temperature as possible (inside is ready for environment temperature and is compensated with target temperature).Mainly
Due to environment temperature interference measurement target, there are two factors：First, the distance between sensor and target setting distance be
It is mainly that infrared sensor irradiates range of receiving as taper using the oblique 45 ° of collecting temperatures in edge, according to datasheet during 40mm
The 45° angle that can be found and set herein just includes the maximum tapered receiver range of sensor, avoids ring to greatest extent
Interference effect caused by the temperature of border.
Pot uses the design of trilaminate material, and the purpose designed in this way is that 430 magnetic stainless steels can be easy to by electromagnetism
Heating, and fine aluminium and the 304 stainless steel capital are poor to electromagnetic induction effect.The specific heat capacity of fine aluminium is more than 430 magnetic stainless steels and 304
Stainless steel, so having good energy storage effect, the raising and lowering that kettle temperature can be allowed more flat.Pot interior surface layers are 304
Stainless steel, can be to salt, and oil waits condiment to have very strong corrosion-resistant effect.So because of collection when pot is by electromagnetic heating
Skin effect and eddy current effect, what is be initially heated is fine aluminium heat absorption of 430 magnetic stainless steel of outer surface Jing Guo different specific heat capacities
It is transmitted to 304 stainless steel of inner surface.Three layers of temperature is resulted in differ in this way.And the pot of intelligent machine for stir-frying dishes rotates always,
So can only temperature be measured to it using non-contact infrared.And hull-skin temperature can only be measured.And the temperature that we need
It is a pot internal surface temperature.So it has to calculate equation of linear regression and dissipated power to predict the kettle temperature of subsequent time.
Needed to pay attention to when calculating kettle temperature by linear regression after actual acquisition temperature in pot is oil, water or dish.Corresponding time
Return equation coefficient also different.
Embodiment 1, according to pot inner wall during analysis of experimental data sky pot and outer wall of wall temperature such as following table (DEG C)：
It can be seen that (y) and pot wall (x) are closed in pot when regression equation y=0.7784x+11.085 is empty pot in table
It is (actual samples data are primary every 5s).Dispersion ratio proves that real data is very accurate for 0.9961.
It can similarly show that the relation curve when being equipped with oil in pot (with oily heavy wool is few only has relationship with deviation ratio) is in
Logarithmic function is arranged.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
With within principle, any modification, equivalent replacement, improvement and so on should all be included in the protection scope of the present invention god.
