Number in the figure: 1 solenoid, 2 pedestals, 3 helix tubes, 4 pots, 5 plane platens, 6 disk coils.

Below, in conjunction with the accompanying drawings the utility model is further described by the specific embodiment.

The specific embodiment:

Referring to Fig. 2 (a), Fig. 2 (b), in the present embodiment, the solenoid 1 of electromagnetic oven is set to the version of helix tube 3, in concrete the enforcement, the lead that is used for coiling helix tube solenoid 1 is a multiply, and the lead of coiling upwards is single or multiple lift in the footpath of helix tube 3, form in the axial direction close around.

Routinely, can in the coil of coiling, settle poly-magnetic material, be beneficial to converging of magnetic field.

Referring to Fig. 3, adopt the version of support, be support with helix tube 3, the pot 4 of round bottom is directly placed on this support.

In concrete the enforcement, have at least following several form to adopt, comprising:

As shown in Figure 3, uncovered helix tube 3 protrudes from electromagnetic oven pedestal 2, and the pot 4 of round bottom is placed on the support that is formed by helix tube 3, and the pot for flat also can directly be placed on its mouth of pipe or in the mouth of pipe and use.

As shown in Figure 4, being similarly uncovered helix tube 3 is to be embedded in the electromagnetic oven pedestal 2, and this form structure is more compact, and the pot 4 of round bottom is placed on the support that is formed by helix tube 3, pot 4 for flat can directly be placed on its mouth of pipe or in the mouth of pipe and use.

As shown in Figure 5, helix tube 3 is embedded in the electromagnetic oven pedestal 2, and is encapsulated as platform by plane platen 5, and outer shape is identical with prior art, is exclusively used in flat pot 4, no matter the bottom surface diameter of pot 4 is greater than or less than nozzle diameter.

Relevant principle analysis is as follows:

As shown in Figure 1, the lead total length of establishing coiling is l, considers the peptide effect that becomes of high frequency electric, lead generally is made up of multiply, and the equivalent diameter of establishing stranded conductor is d, and corresponding first lap radius is d, the second circle radius is 2d, and L last lap radius is made as R, is then got by geometrical relationship:

2π(d+2d+...+R)＝l

As shown in Figure 2, the lead of same length, the coiled radius is the solenoid of R, then total number of turns n satisfies:

n2πR＝l

If while indirect current i (t)

For the disk coil in the prior art shown in Figure 1, ignore cancellation effect, then total magnetic flux is:

${\mathrm{\&phi;}}_{m1}=\frac{u_{0}i\left(t\right)}{2d}\mathrm{\&pi;}{\mathrm{<figure-callout\; id="2"\; label="d"\; filenames="Y20072004421000081.png"\; state="\{\{state\}\}">d</figure-callout>}}^2+\frac{u_{0}i\left(t\right)}{2\left(2d\right)}\mathrm{\&pi;}{\left(2d\right)}^2+L\frac{u_{0}i\left(t\right)}{2R}\mathrm{\&pi;}{\mathrm{<figure-callout\; id="2"\; label="R"\; filenames="Y20072004421000081.png"\; state="\{\{state\}\}">R</figure-callout>}}^2$

For solenoid in the present embodiment, total magnetic flux is:

${\mathrm{\&phi;}}_{\mathrm{<figure-callout\; id="2"\; label="m"\; filenames="Y20072004421000081.png"\; state="\{\{state\}\}">m</figure-callout>}2}=n{u}_0\frac{1}{d}i\left(t\right)\mathrm{\&pi;}{\mathrm{<figure-callout\; id="2"\; label="R"\; filenames="Y20072004421000081.png"\; state="\{\{state\}\}">R</figure-callout>}}^2$

Know by Faraday's electromagnetic induction law:

The induced electromotive force that disk coil shown in Figure 1 produces is:

${\mathrm{\&epsiv;}}_1=\frac{u_{0}i\left(t\right)}{2d}\mathrm{\&pi;}{\mathrm{<figure-callout\; id="2"\; label="d"\; filenames="Y20072004421000081.png"\; state="\{\{state\}\}">d</figure-callout>}}^2+\frac{u_{0}i\left(t\right)}{2\left(2d\right)}\mathrm{\&pi;}{\left(2d\right)}^2+L=\frac{u_{0}l}{4}i\left(t\right)$

The close induced electromotive force size that produces around solenoid is in the present embodiment:

${\mathrm{\&epsiv;}}_2=n{u}_0\frac{1}{d}i\left(t\right)\mathrm{\&pi;}{R}^2=\frac{u_0\mathrm{Rl}}{2d}i\left(t\right)$

In actual applications, $\frac{R}{2d}>>\frac{1}{4},$ So ε ₂＞＞ε ₁Therefore, the vortex current that the present embodiment specific embodiment induces on the pan of identical material is bigger, and the thermal efficiency is higher, and is also more energy-conservation.

If consider the magnetic field cancellation effect in the plane disc coil, then the magnetic field that excites of disk is littler, and the induced electromotive force of its generation is littler, so the close thermal efficiency and the energy-saving effect around the solenoid type coil under the identical situation is more remarkable.
