Ground；Cooking pan is adequately exposed to the thermal treatment zone and forms shielding cover body by the thermal treatment zone, panel and radiation absorption layer.
Being additionally provided with multiple temperature sensor on the described thermal treatment zone, multiple temperature sensors are arranged along same circumference, temperature
Spend the temperature of sensor acquisition cooking pan diverse location and on guidance panel, show mean temperature.
Being additionally provided with alarm on described guidance panel, alarm connects the PLC of electromagnetic oven, and PLC is according to diverse location
Temperature sensor gather temperature control alarm equipment alarm.
Power ground after described panel, the thermal treatment zone and radiation absorption layer connects and in power line connects.
The material of described radiation absorption layer be metallic plate, metal spraying material, conductive film layer, electrically-conducting paint, conductive paste,
One in conductive fabric, conductive paper.
It is provided with two thermals treatment zone on described panel, is respectively used to frying pan and steamer；The thermal treatment zone of frying pan is hemispherical
Structure, the thermal treatment zone of frying pan is cylindrical structure.
Described cooking pan ferrum or other magnetic conductive materials are made.
Relative to prior art, this utility model has the advantage that
This electromagnetic oven structure is simple, with low cost, elimination radiation effect is good, highly versatile.Can also well eliminate electricity
The electromagnetic radiation that magnetic furnaceman reveals in making, it is ensured that the security context of user.By the design of the Embedded thermal treatment zone of plano-concave, keep away
Having exempted from the problem that plane heating district easily radiates, plano-concave damascene structures can effectively increase electromagnetic conversion efficiency, moreover it is possible to right
Electromagnetic radiation has the effect that secondary stops, is absorbed by conductive shielding material, has almost accomplished the effect of full-shield.
Further, the addition of temperature sensor can monitor cooking pan bottom temp in real time, is shown to user and checks,
Convenient grasp adds the duration and degree of heating.
Further, alarm can be by the temperature of diverse location bottom circumference temperature sensor test cooking pan respectively
Degree, and then judge bottom cooking pan the best with the laminating of the plano-concave Embedded thermal treatment zone, and then instruct operator more preferable
Note the position adjustment of radioprotective and cooking pan.
