Amount is constantly changing, and needs that controller is avoided to be frequently changed heating gear at this time.In actual implementation, initial power heating time
It can be set as 3-5 minutes.
T acquires temperature signal and weighing unit that temperature measuring unit is sent at set time intervals for step 2, control unit
The weight signal of transmission；Further, control unit by collected temperature signal and weight signal and a upper time interval it
The temperature signal and weight signal of preceding acquisition are compared respectively, and calculate temperature variation and weight change amount.Specifically,
Control unit is by t1Moment collected temperature signal T1With weight signal W1With last moment t0The temperature signal T of acquisition0Again
Measure signal W0Mathematic interpolation is done respectively, obtains t1The temperature variation △ T at moment1With weight change amount △ W1.The temperature change
Measure △ T1With weight change amount △ W1There is sign, respectively represents the incrementss and decrement of temperature or weight.
I.e.：
And so on, it will be understood by those skilled in the art that the subscript in the present invention distinguishes different moments, such as t1Refer to
Generation " current time ", t2It refers to " subsequent time ", t0It refers to " previous moment ", by calculating, the temperature of any time can be obtained
Variable quantity and weight change amount.
After step 3, initial heating time, control unit judges that the weight decrement of heating vessel or cookware is more than the
One threshold value, while temperature increase is zero, control unit reduces the heating power of the heating unit, in practical operation, when
△W1Absolute value be more than first threshold, while △ W1For negative, you can think that the weight decrement of heating vessel or cookware is more than
First threshold.The first threshold represents whithin a period of time, and slaughterhouse is because of the weight that moisture evaporation is lost, when the water in slaughterhouse
When reducing the moisture of first threshold weight, it is necessary to reduce the case where heating power is to prevent dry pot, which can be according to practical feelings
Condition is set, such as is set according to the size of electromagnetic oven and the size of applicable cookware, and the general first threshold is set as

In more precise control, control unit judges that the weight decrement of heating vessel or cookware obviously increases, simultaneously
Temperature increase is zero, and control unit reduces the heating power of the heating unit.When reaching boiling due to slaughterhouse, the steaming of moisture
Hair is more violent than initial heating time, therefore the weight decrement of heating vessel caused by moisture loss or cookware has significant increasing
It is long, in practical operation, as △ W1Absolute value reach △ W01.5 times of absolute value, while △ W1For negative, so that it may to regard
For t1The weight decrement of moment heating vessel or cookware obviously increases, at the same time, due to the boiling of slaughterhouse, the temperature of pot body
Also reach a stable point, and the incrementss of temperature are gone to zero.In practical operation, as △ T1Absolute value be less than 0.1
DEG C when (control unit judge be the corresponding temperature signal amplitude of variation of its Celsius temperature) can be considered that temperature increase is zero.Institute
It states control unit and reduces the heating power of the heating unit it can be appreciated that reducing the gear of heating power.By sentencing simultaneously
Disconnected temperature change value and weight change value further improve the accuracy of slaughterhouse fluidized state judgement, when water is not yet in pot

Power.
After step 4, initial heating time, control unit judges that the weight gain of heating vessel or cookware is more than the
Two threshold values, while temperature reduces, control unit increases the heating power of the heating unit.In practical operation, as △ W1's
Absolute value is more than second threshold, while △ W1For positive number, you can think that the weight gain of heating vessel or cookware is more than second
Threshold value.When the second threshold represents the moisture that constant weight is added in slaughterhouse, and cause the reduction of slaughterhouse temperature, it is necessary to carry
High heating power is so that slaughterhouse boils again, which can be set according to actual conditions, such as 30-50g, also can be according to reality
Situation is set, such as is set according to the size of electromagnetic oven and the size of applicable cookware, general second threshold setting
To be applicable in 1/10th or so of cookware maximum capacity.
In more precise control, after initial heating time, control unit judges the weight of heating vessel or cookware
Incrementss obviously increase, while temperature reductions obviously increase, and control unit increases the heating power of the heating unit.Due to
Jia Tang or add water when or user toward amplification quantity food materials in pot when, the weight of pot body can significantly increase (step growth), simultaneously
The temperature of pot body can significantly reduce, in practical operation, as △ W1Absolute value reach △ W01.5 times of absolute value, while △
W1For positive number, so that it may to be considered as t1The weight gain of moment heating vessel or cookware obviously increases, as △ T1Absolute value reach
△T01.5 times of absolute value, while △ T1For negative, so that it may to be considered as t1The temperature reductions of moment heating vessel or cookware
It obviously increases.Described control unit increases the heating power of the heating unit it can be appreciated that improving the shelves of heating power
Position.Equally, it by judging temperature change value and weight change value simultaneously, further improves slaughterhouse and adds the accurate of water state judgement
Property, when user is put into a small amount of food materials without adding water, when slaughterhouse temperature is not substantially reduced, control unit, which will not increase, to be added
Thermal power.
After step 5, initial heating time, control unit judges the absolute of the weight change amount of heating vessel or cookware
Value is equal or close to third threshold value, maintains current heating power.The third threshold value is the weight of pot cover.The third threshold value can
By presetting, can also be judged by control unit.As the △ W at control unit calculated n momentnAbsolute value in,
Repeat some fixed value, (such as occurrence number is at 5 times or more), control system judges the absolute value △ W of the fixed valueLFor
Lid weight, and third threshold value is set to, when the absolute value of the weight change amount of heating vessel or cookware is equal to or connects
When the nearly third threshold value, maintain current heating power constant, controller caused by removing or putting pot cover to avoid user is accidentally grasped
Make.Because general user is while covering pot cover or removing pot cover, will not simultaneously plus water or feeding, and cover pot cover or
It removes pot cover usually to complete at 1-2 seconds, therefore sets the sampling time in step 1 as 1-2 seconds.The weight change amount it is absolute
It is close that value close to third threshold value refers to that its error is considered as within 1%.
Electromagnetic oven proposed by the present invention and Electromagnetic Control method make the automated power control of electromagnetic oven more intelligent, section
The about energy, and can judge that user covers pot cover and opens the action of pot cover, the maloperation of controller is avoided, control is improved
