" the formula parameter " includes " holding temperature ", " temperature offset value ", " single valve aperture ", " temperature control tolerance ", " middle side
The temperature difference ", " sampling period ".Food needs the temperature being maintained after the completion of " holding temperature " sign food cooking, so that food
Temperature is suitable for eating at any time." temperature offset value " characterizes the correcting parameter being modified to the temperature control deviation of pan temperature, uses
To correct deviation of the pot temperature relative to design temperature of temperature sensor control, so that pan（Bottom interior surface）It is heated
Temperature is consistent with desired design temperature.The factor for causing temperature sensor to produce temperature control deviation includes：The position of temperature measuring point,
Difference, the difference of temperature sensor assembling deviation and pan in itself of temperature sensor in itself（Such as thick, thin, material）Deng.Temperature
The measured value of the pan temperature of degree sensor detection is numerically inclined with the setting value of temperature and temperature that are obtained from formula table
Shifting value and be worth consistent, such pan（Bottom interior surface）Heated temperature reach the setting value of temperature.For example, pan
The preferred temperature of bottom interior surface is 100 DEG C, is 100 DEG C by the setting value value of temperature, is detected by temperature sensor
Temperature measuring point is located at the lower surface of pan bottom, there is thermal resistance between the lower surface and inner surface of pan bottom, then works as temperature sensor
Detection temperature when being 100 DEG C, the temperature of pan bottom interior surface is less than 100 DEG C, may be such as 98 DEG C, be not reaching to setting temperature
Degree, the i.e. deviation in the presence of 2 DEG C, this temperature deviation can be corrected by temperature offset value, and temperature offset value is set into 2 DEG C.
In this case, the setting value of temperature is that 100, temperature offset value is 2 DEG C, then the target temperature of temperature sensor detection is 102
DEG C, when the temperature that temperature sensor is detected reaches 102 DEG C, the temperature of pan inner surface reaches 100 DEG C of the temperature of setting, that is, reaches
To preferred temperature.For example, when having changed temperature sensor, due to temperature sensor difference in itself and assembling deviation so that
The thermal condition of pan is changed, and needs to carry out mode to the thermal condition of pan before use, so that formula table is applied to new heat
The pan of operating mode.A kind of optional mode method, e.g., in a certain desired temperature T0Lower heating pan, it is other using high one-level
Thermo detector measures the temperature value T of pot bottom inner surface1, the size of heat power of gas burner is adjusted, makes T1And T0Equal, now temperature is passed
The measured value for the pot temperature that sensor is detected is Tc, the measured value Tc and desired temperature T of the pot temperature0Between difference can be with
It is used as the initial set value of temperature offset value.In addition, temperature offset value can be also used for each formula step temperature in adjustment culinary art formula
The setting value of degree, e.g., temperature offset value increase by 2 DEG C, and the setting value equivalent to each formula step temperature in culinary art formula increases by 2 simultaneously
℃.The setting value of temperature offset value is changed, equivalent to the setting that each formula in the overall formula table of translation up or down walks temperature
Value, can make same formula table be applied to different-thickness, the pan of unlike material, and can correct the assembling of temperature sensor
The difference of deviation and thermocouple in itself, so that formula table is applied to pan." the middle side temperature difference " characterizes the uniformity of pan temperature, its
Represent the maximum temperature difference allowed in the middle part of pan between edge." single valve aperture " is characterized as the 1st proportioning valve 122a ＇（Correspond to
Interior ring fire, small fire）Valve opening be less than single valve aperture setting value when, the 2nd proportioning valve 122b ＇（Corresponding to outer ring fire, big fire）
Closed by controller；It is to be understood that now, the firepower of burner is smaller, when the 1st proportioning valve 122a ＇'s for controlling small firepower
Valve opening is less than the setting value of single valve aperture, when such as 10%, and the 2nd proportioning valve 122b ＇ of control high flame are closed by controller 20,
Now the firepower of burner is smaller, is the small firepower heating period, and such as pancake, cooked rice generate the stage of crispy rice, in this stage
The temperature difference that the temperature in the middle part of pan, pan and edge can also be alternately heated using inside and outside ring fire is less than the middle side temperature difference
Setting value, is heated properly pan, improves the cooking quality of food." temperature control tolerance " characterizes the controlled object temperature phase of pan
For the fluctuation range of desired temperature in culinary art formula；For example, temperature control tolerance is 2%, represent that controller allows pan temperature
Measured value（That is controlled object temperature）The relative value of the maximum deviation of fluctuation range between pan desired temperature is 2%, than
Such as：If pan desired temperature is that 100, temperature control tolerance is 2%, the measured value of pan temperature（That is controlled object temperature）In 98-
Between 102, then it is assumed that pan measured temperature and pan desired temperature are suitable.The relative value of temperature deviation is defined herein as：
Relative value=ABS of temperature deviation（The setting value of measured value-temperature of temperature）The setting value * 100% of/temperature, for relative value
Definition similarly hereinafter." sampling period " characterization control device implements the frequent degree of control to heat power of gas burner size.Sampling period quilt
What is set is smaller, and control of the controller to heat power of gas burner size is more accurate.
It should be noted that being configured with " redirecting temperature ", " valve opening ratio " and " valve in working as the formula parameter for cooking formula
During the setting value of control aperture ", " firepower control mode ", " opening ratio " and " valve opening " can be saved in the formula table for cooking formula
Controlled variable.Thus, the formula table and formula parameter of another optional culinary art formula are as follows, only include in its formula table
The setting value of " temperature " controlled variable and the setting value of " time ".
Formula table：
| Formula is walked | Time（/Min） | Temperature（/℃） |
| 1 | 5 | 60 |
| 2 | 3 | 80 |
| 3 | 3 | 95 |
| 4 | 5 | 105 |
| 5 | 3 | 102 |
| 6 | 20 | 102 |

Cook " redirecting temperature " in formula and characterize the firepower control mode of burner from valve control mode to temperature control mode or by temperature
Prosecutor formula to valve control mode change when temperature spot, the setting value of temperature is redirected when the measured value of pan temperature is less than, using valve
Prosecutor formula is heated, and when the measured value of pan temperature is higher than the setting value for redirecting temperature, is heated using temperature control mode." valve opening ratio "
The relevance of the 1st proportioning valve and the 2nd proportioning valve is characterized, its value is defined as the valve opening of the 2nd proportioning valve and the 1st proportioning valve（Also may be used
To be the valve opening of the 1st proportioning valve and the 2nd proportioning valve）Ratio." valve control aperture " constitutes electricity when being characterized in the valve control mode stage
Control the 1st proportioning valve of flow valve（It can also be the 2nd proportioning valve）The opening value of the target opening value reached, such as 80%, and the 2nd ratio
The valve opening of example valve reaches the valve opening of the 1st proportioning valve and the product of valve opening ratio.Such a optional culinary art formula, its formula table
Only one of which controlled variable " temperature ", very succinctly, unfortunately, in valve control mode stage the 1st, the valve opening of the 2nd proportioning valve
For a steady state value, the inhomogeneities of pan middle part and edge temperature can not be adjusted.
Need to illustrate again is：It can not include " firepower control mode ", " opening ratio " and " valve opening " in culinary art formula
Controlled variable, and formula parameter does not also include the parameter of " redirecting temperature ", " valve opening ratio " and " valve control aperture ", culinary art now
The setting value of temperature is only included in formula, whole cooking process is only with temperature control, in each controlling cycle, makes pan temperature
Measured value reach setting value.Now, the composition of culinary art formula is very succinct, also allows for user behaviour and does.
Also needing to explanation is：When the 1st proportioning valve 122a ＇ and the 2nd proportioning valve 122b ＇ metered flow are identical, i.e., opened in valve
When the 1st proportioning valve 122a ＇ and the 2nd proportioning valve 122b ＇ flow are identical in the case of degree identical, cooking must in the formula table of formula
" opening ratio " controlled variable is needed, the ratio of the valve opening for adjusting the 2nd proportioning valve 122b ＇ and the 1st proportioning valve 122a ＇,
2nd proportioning valve 122b ＇ valve opening is more than the 1st proportioning valve 122a ＇ valve opening, makes the combustion gas stream of the outer ring fire of inflow burner
Amount is more than the flow for the combustion gas for flowing into interior ring fire, so that the firepower of burner outer ring fire is more than the firepower of interior ring fire, so, favorably
