Molding block 20 then judges the collocation degree of cookware and electromagnetic heating system for low collocation degree, and control electromagnetic heating system is default with third
Power is heated, wherein third predetermined power is less than the second predetermined power.
Wherein, the first predetermined threshold value and the second predetermined threshold value can be able to be with hexadecimal representation, such as the first predetermined threshold value
9A, the second predetermined threshold value can be 80.
That is, control module 20 opens pulsewidth by comparing what power under identical goal-selling power opened pipe,
The collocation degree of different cookwares and electromagnetic heating system is distinguished, for the good cookware of suitability, the open-minded of setting can be reached
Pulsewidth, that is, first threshold can assign high power i.e. the first predetermined power to electromagnetic heating system and heat.It is bad for suitability
Cookware, setting is just not achieved opens pulsewidth i.e. the first predetermined threshold value, and lower power i.e. the can be assigned to electromagnetic heating system
Two predetermined powers or third predetermined power are heated.
As a result, by the way that the difference of cookware is embodied in opening for power switch tube in pulsewidth, then by identical default
The difference for opening pulsewidth of power switch tube under target power assigns suitability bad cookware low-power, to effectively be promoted
The service life of electromagnetic heating system.
