Intelligent thermal source electric cooker
Technical field
It the utility model is related to electric cooker technical field.
Background technology
The core technology of in the market middle and high end electric cooker is the IH electromagnetic heating techniques that developed country uses in one's early years.Electromagnetism is dirty
Environment is contaminated, is the interference source in the microelectronics world, especially low-frequency magnetic leakage is the destruction source of nerve system of human body, and World Health Organization is to reach
Into common recognition.IH electromagnetic heating techniques are by solenoid ON alternating current, and by multi-pole coils, producing magnetic field realizes pair
The electromagnetic eddy heating of localized magnetization material, is magnetic force line cutting eddy heating for heating, is not cubic heat source.The consumption of IH heating techniques is big
The copper resource of amount, pollute cleaning ambient.In addition, the electron temperature-control technology of developed country falls behind relatively.Some products are to reach vertical
The purpose of body heating, the very high saturated vapor spout of humidity ratio is set on pot cover, and saturated vapor heating is it is difficult to meet multi-functional
Culinary art demand.Such as:Cook congee using boiling rolling, rice need not then seethe with excitement rolling control technology.Bottom electromagnetic heat source is made
Meter Zhong Shui is heated with the bottom of a pan, produces steam, steam rises with overhead vapor thermal source to holding, and the eddies of water is formed in food.Design is not
Only lack reasonability, and it is unnecessary, it is pseudo- three-dimensional heating.Abroad, electromagnetism is made using electromagnetic heating technique by domestic enterprise
KPa pot, hundred kPas of pots, it is mainly using pressure temperature control method in courage.
