The rotation speed of the heat and blender that are applied in cooking space 2 is controlled, resistance indication signal indicates to be cooked in cooking space 2
The current resistance for the foodstuff 3 (as shown in Figure 3) prepared food, wherein resistance indication signal is generated by means of blender 4.
Fig. 3 shows the cooking space 2 of the cooker 1 during foodstuff 3 is cooked.In Fig. 3, blender 4 is stirred
It mixes element 14 and is driven by actuator 15 along direction of rotation 21 counterclockwise.Since the evaporation of liquid improves, the resistance of foodstuff 3 increases
Add.The accumulation of foodstuff 3 is on the first side 8 of agitating element 14 as a result, so that second of the agitating element 14 in blender 4
Empty space 13 is formed on side 9.Therefore, the first temperature on the first side 8 of agitating element 14 and first pressure are higher than second side 9
On second temperature and second pressure.
Fig. 4 shows the first curve 23 of the determination power consumption of actuator 15, during cooking which depict foodstuff 3
Power consumption trend.Fig. 5 shows between first pressure and second pressure the second curve 24 of constant-pressure difference really, and which depict foods
Pressure difference trend during the culinary art of object material 3.Fig. 6 shows the third curve 25 of the first temperature and the 4th curve of second temperature
26, the trend of the first temperature and second temperature during being cooked which depict foodstuff 3.In all figures, starting point t1 is liquid
Body (such as water) starts to evaporate, so that the resistance of foodstuff 3 starts to increase, and generates the time in empty space 13.It is originating
Before point t1, foodstuff 3 and liquid are heated, and actuator 15 power consumption and pressure difference it is substantial constant (referring to
Fig. 4).In addition, before starting point t1, pressure difference is close to 0 (referring to Fig. 5), and first on the first side 8 of agitating element 14
Second temperature in temperature and second side 9 increases in parallel, i.e., roughly the same (referring to Fig. 6).At starting point t1, empty space
13 occur, and the second temperature in second side 9 of agitating element 14 starts the on the first side 8 different from agitating element 14

Stop the tune to the rotation speed for the heat and/or agitating element 14 being applied in cooking space 2 by data feedback system 12
Section.Particularly, data feedback system 12 closes the rotation of heat source 5 and/or agitating element 14 at end point t2, and notifies user
The cooking process of foodstuff 3 is completed, for example, via display 17 (as shown in Figure 1) and/or audible signal.This means that
At end point t2, foodstuff 3 sufficiently cooked and/or foodstuff 3 in liquid nearly completely or completely evaporate.In
In y-axis, the temperature of the power of Fig. 4, the pressure difference of Fig. 5 and Fig. 6 is shown respectively with arbitrary unit, and x-axis then shows arbitrary unit
Time.
It should be understood that data feedback system 12 can separately detect to each independent variable element, (i.e. electric power disappears
Consumption, temperature difference and pressure difference) reach transition point t2.Moreover, system can be set to one, two be used only in these parameters
Or three.Algorithm can be used to determine and have arrived at transition point t2 in system 12, for example, with the prompting of parameter based on one or more
User's food cooking is completed and/or closes heating and stirring.For example, when only one parameter reaches t2, or if extremely
When parameter reaches t2 there are two few, or if system 12, which is assured that, reaches transition point t2 when three parameters reach t2.
As described above, data feedback system 12 can by will (power consumption, temperature difference and pressure difference) monitor value with
Predetermined threshold is compared, to determine the transition point t1 and t2 that have reached for each parameter.
Under the specific condition of power consumption, the slope (i.e. gradient) of the first curve 23 is compared with initiation threshold,
It may thereby determine that the variation at t1 --- figure 4, it is seen that slope starts to become rising from flat at t1, function at this time
Rate accelerates and consequently reaches the stabilization increase state at t2.Therefore, slope and zero threshold value or low positive-valued threshold can be compared
Compared with.By the way that the absolute value of power E to be compared with threshold value, it can detecte and reach transition point t2, which is shown as the midpoint Fig. 4
The value of E at t2.
In the case where pressure difference, as shown in figure 5, by the slope of curve 24 and the initiation threshold and inspection that detect transformation t1
The end threshold value for measuring t2 is compared.At t1, slope starts to increase to zero or more or low stationary value.At t2, slope subtracts
Value as low as more lower than value between t1 and t2.Therefore, after slope is more than first threshold (at t1), system 12 is detected
When slope is back to predetermined second threshold (at t2)；Due to these threshold values can be it is similar, system can pass through
Time delay distinguishes event at t1 and t2 by using the absolute value of Δ P.
In the case where temperature difference, as shown in fig. 6, by temperature difference and initiation threshold between the temperature T of slope 25 and 26
(usually zero) is compared, and has reached t1 with determining when temperature difference is more than the threshold value；And by the temperature difference and terminate
Threshold value (such as 5 DEG C) is compared, and has reached t2 with determining when temperature difference is more than the threshold value.
Type due to food and the recipe for cooking food will affect content liquid and its variation in cooking process
Rate, and influence transition point t1 and t2 and by the power occurred in the transition point, temperature and pressure level it is other important
Factor, so the input information about food and/or recipe can be used for improving this method, especially data feedback system 12
Operation.For example, foodstuff input information and/or recipe can be used for changing for determining one for having reached t1 and/or t2
Or multiple threshold values.By being used as one or more monitoring parameters (i.e. power consumption, pressure difference or temperature difference) for determining t1
And/or the basis of algorithm that t2 has reached, these information can be used for changing the algorithm, because the opposite of these parameters can
It may change with the difference of food type and cooking method by property.
