Specific embodiment
Embodiment one
As shown in Figure 1, in the present embodiment, a kind of electromagnetic heater, including induction coil 100 and magnetic core 200, it is described
Induction coil 100 is arranged on magnetic core 200, and the conducting wire of the induction coil 100 is gradually increased by density from inside to outside.For existing
With the presence of electromagnetic heater heat non-uniform phenomenon, by constantly analyzing test, it is found that existing electromagnetic heating fills
It sets, the coil of induction coil 100 by being evenly arranged from inside to outside.In fact, each wire on induction coil 100, all
Around without several magnetic lines of force, all magnetic lines of force are all closures.That is, the magnetic line of force comes out in conducting wire side, from another
Side is entered, and when induction coil 100 is coiled into discoid, since the arc length of inside is less than outside, the magnetic flux density of inside is greater than outer
Side, after the magnetic line of force superposition of multiple conducting wires, induction coil 100 forms an annular vortex, and annular inside temperature is higher than
Outside.So the magnetic line of force that this existing mode can make induction coil 100 generate is concentrated toward center, and edge is then opposite
It is weaker, that is, when heating, the temperature of inside can be higher than the temperature of edge, cause phenomenon of being burned.Therefore, this programme passes through setting
The conducting wire of induction coil 100 is gradually increased by density from inside to outside, so that the magnetic line of force that induction coil 100 generates is in cookware 400
Upper distribution is more uniform, so that heating is more uniform.
Preferably, in the present embodiment, the wire spacing of the horizontal direction of induction coil 100 by being gradually reduced from inside to outside.
That is, by the wire spacing for the horizontal direction for changing induction coil 100, so that the magnetic line of force that induction coil 100 generates is in cookware
It is evenly distributed on 400.
Preferably, the induction coil 100 has multiple groups conducting wire, and the number of turns of each group conducting wire by gradually increasing from inside to outside.I.e.
Induction coil 100 is made of multiple groups conducting wire, is more than that group conducting wire close to inside close to the number of turns of that group conducting wire in outside
