Electromagnetic induction coil be positioned at plane kitchen range face and concave focus surface below.Circuit part is to promote two cover power amplifier modules and two cover electromagnetic induction coils by a cover micro computer driving governor.Realize multi-purpose cooker, enlarged the scope of application of electromagnetic stove.

Five, invention effect:

1, when using the cooking of matrix pot, can also use pan to cook and praise a job such as soup, save cooking the time of labour intensity maximum.

2, electromagnetic stove is complete environment-friendly products, does not have any waste gas, and pollutions such as dust are the zero contamination type environment-friendly products that are worth promoting.

3, owing to directly make the bottom of a pan heating, there is not heat conduction losses, so firing rate is fast, overall efficiency is high.

4, electromagnetic stove is an energy conversion equipment efficiently, and conversion efficiency can reach more than 96%, and traditional coal furnace only has 48%, and gas range also has only 55%, is one of energy-efficient product.

5, owing to adopted the high-power structure of kick pot, make China have time-honored matrix pot and in new kitchen range field, fully played.

Six, accompanying drawing and drawing explanation:

Fig. 1 is the elevational cross-sectional view of the utility model structure;

Fig. 2 is a circuit working schematic diagram of the present utility model.

Wherein:

1-plane kitchen range electromagnetic induction coil, 2-planar coil carriage, 3-fixed screw, 4-nail pin, 5-concave focus surface, 6-fixed support pin, 7,12-magnetic detection switch, 8-stove, 9-circuit control panel, 10-power amplifier module radiator, 11-matrix coil bracket, 13-matrix electromagnetic induction coil, 14-cooling blower, 15-stove feet, 16-air outlet, 17-air inlet.
