When steam bubble contacts the first foam inductive component 101A and the second foam inductive component 101B simultaneously, capacitance detecting chips 20
The second foam detection signal is generated, wherein, the second foam detection signal is chip readable signal such as data signal, capacitance detecting
Chip 20 is sent the second foam detection signal to main control chip 30 by being communicated with main control chip 30.
Further, if main control chip 30 receives only the first foam detection signal, i.e. only the first foam sense group
Part 101A capacitance changes, then judges that boiling is not enough, spillover does not occur for electric cooking pot, and main control chip 30 controls electricity
Cooking pot keeps present output power constant；If main control chip 30 is received again after the first foam detection signal is received
Second foam detects that signal, i.e. the first foam inductive component 101A and the second foam inductive component 101B capacitance become
