Equivalent inductance L0 in LC resonance circuits is made up of electromagnetic coil disk L1 and pot 6, and pot 6 is with respect to magnet coil
Disk L1 distance change and pot 6 because temperature change all can caused by equivalent inductance L0 change, so as to influence LC resonance circuits
Resonant frequencyBy resonant capacitance C1 and resonant capacitance C2 equivalent capacity C0, magnet coil
The series resonant circuit that the equivalent inductance L0 that disk L1 and pot 6 are constituted is constituted, the equiva lent impedance of LC resonance circuits | Z | it is with stream
The power frequency f changes crossed in LC resonance circuits：When the timings of load input voltage AC mono-, power frequency f more deviates load resonant
Frequency f0, equiva lent impedance | Z | bigger, the power of output is smaller；Work as f=f0When, equiva lent impedance | Z | minimum, the power now loaded
It is maximum；Work as f>f0When, equiva lent impedance | Z | in perception and the bigger induction reactance of frequency is bigger, power output is smaller；As f ＜ f0When, it is equivalent

Voltage magnitude is simultaneously sent to microcontroller, and the power (power=input voltage * input electricity of electromagnetism soup stove is calculated by microcontroller
Stream).
Step S2. detects the weight P of electromagnetism soup stove by pressure sensor 34 in detection cycle tt, LC resonance circuits
Load resonant frequency ft, when judging testing result PtRelative to upper detection cycle t-1 testing result Pt-1When changing,
The load resonant frequency f of LC resonance circuits when calculating detection cycle ttThe resonant frequency f of a relatively upper detection cyclet-1Change
Change amount △ f (i.e. △ f=ft-ft-1), by microcontroller by changing the pulsewidth of control port output pwm signal adjusts driving
Circuit output makes the driving signal frequency f ' of t+1 detection cycles to the frequency f' of the drive signal of inverter circuitt+1Relative detection
Cycle t driving signal frequency ft' also become big △ f, i.e. f 't+1=ft'+△f。
Therefore, drive circuit is adjusted by changing the pulsewidth of control port output pwm signal by microcontroller to export
To the frequency of the drive signal of inverter circuit, driving signal frequency f' is set also to follow the load resonant frequency f of LC resonance circuitstTogether
To, same amount change △ f, so that driving signal frequency f' is slightly above resonant frequency ft, make LC resonance circuits close to resonance shape
Electromagnetic coil disk L1 electric current is uprushed and electromagnetism soup stove is kept higher power output in state, LC resonance circuits, so as to improve
The efficiency of heating surface.
Certainly, when detecting the reduction of the cooking of pot 6 by pressure sensor, now microcontroller will detect resonance
The △ f that diminish of frequency, while also changing the power output for detecting electromagnetism soup stove, by microcontroller by changing pwm signal
Pulsewidth make the driving signal frequency follow resonant frequency also to diminish △ f.
Step S3. now corresponds to pot 6 and cooked when the weight of electromagnetism soup stove persistently reduces and is reduced to initial weight P0
Thing of preparing food is reduced to without cooking, in order to prevent dry combustion method, and now microprocessor control thumper, which is sent, alarms and close input
Power supply, is stopped.
Certainly, in order to prevent erroneous judgement, a time restriction can be increased, such as in N number of continuous detection cycle (such as
N is 5~15 natural number) persistently occur just thinking during detected value=initial detecting value P0 of pressure sensor being to continue with heating can
Can occur dry combustion method, now just closing input power makes electromagnetism soup stove be stopped.
