Electromagnetic stove with a plurality of concentric induction coil
Technical field
The utility model relates to a kind of civilian or commercial electromagnetic stove, particularly a kind of electromagnetic stove with a plurality of concentric induction coil.
Background technology
Mostly electromagnetic stove in the market is to adopt single induction coil to heat, and this mode of heating is owing to induction coil is fixing, and the heating surface size that causes being heated pot can not be selected.When often appearance was cooked a bit and a sup, it was overheated to occur at the pot face that does not have food to cover, thereby causes the pan life-span to reduce greatly; And when a large amount of foods were cooked, the food that surpasses the eddy-current heating face that single induction coil covers was difficult to be heated rapidly, made food can't reach the culinary art requirement.On pan life-span and food cooking requirement uniformity, be difficult to accomplish satisfactory to both parties to the difference amount.
The utility model content
Technical problem to be solved in the utility model is that a kind of electromagnetic stove with a plurality of concentric induction coil of controlling the heating surface (area) (HS size according to the quantity of cooking food will be provided.
In order to solve above technical problem, the utility model provides a kind of electromagnetic stove with a plurality of concentric induction coil, the radio-frequency induction coil of electromagnetic stove adopts the sandwich wound coil of a plurality of different-diameters, is nested in same home position, and each sandwich wound coil is used the switch connection high frequency electric source respectively.Control what of the size of heating surface (area) (HS and output energy according to the quantity of heated material effectively, both required heatable substance had fully been heated, also do not waste any energy.
Superior effect of the present utility model is: the heating surface size requires free controlled according to culinary art; Effectively guarantee the pan life-span.

The specific embodiment
Seeing also shown in the accompanying drawing, is that example is described further with four concentric induction coil.
As depicted in figs. 1 and 2, the utility model provides a kind of electromagnetic stove with a plurality of concentric induction coil, the radio-frequency induction coil of electromagnetic stove adopts the sandwich wound coil of four different-diameters, be nested in same home position, each sandwich wound coil is used switch connection high frequency electric source 5 respectively, come selector switch to connect high frequency electric source 5 according to the quantity of heated material effectively, control heating surface (area) (HS the size and output energy what, both required heatable substance was fully heated, also do not waste any energy.
