Abstract
The utility model relates to a device for reducing the electromagnetic induction radiation interference, which is particularly suitable for the anti-interference of radiation among a plurality of inductance coils installed on the same solid material or remotely installed. The device comprises a heating controller (1); the electromagnetic inductance coils (2) are arranged on the heating controller (1); and a magnetic conduction strip (3) is installed at the outer side of each electromagnetic inductance coil (2). The device has the beneficial effect that as the magnetic conduction strips are installed at the outer sides of the electromagnetic inductance coils, the magnetic leakage and the magnetic radiation of a magnetic circuit are effectively reduced, and the purposes of reducing the loss and improving the work anti-interference are achieved.
Description
Technical field
The utility model relates to a kind of reduction electromagnetic induction radiated interference device, especially adapts to a plurality of (more than one) inductance coil radiation anti-interference each other be installed in (or closely installing) on the same solid material.
Background technology
Electromagnetic induction heating changes into high-frequency current with AC energy exactly, and electric current produces high frequency magnetic field through electromagnetic induction coil, and heating object is in high frequency magnetic field, and the magnetic force line cutting heating object produces eddy current and makes the heating object heating.When a plurality of (more than one) electromagnetic induction heating coil is installed on the same heating object (or closely installing), can there be radiated interference each other.Cause the damage of electromagnetic induction heating controller.
Radiated interference; It is the electromagnetic interference of propagating with the electromagnetic wave form through the space; Be present in the middle of communication apparatus or the computer operations facility, it is that circuit or wireless aerial by equipment emits that interference source is partly arranged, in some cases; Maybe be excessive because of amplitude (interference), and cause problems such as wireless radio transmission interruption or computer operations facility fault.
Existing when a plurality of (more than one) electromagnetic induction heating coil is installed on the same heating object (or closely installing) in order to overcome, understand radiated interference each other.Cause the problem of the damage of electromagnetic induction heating controller, the utility model provides a kind of minimizing to be installed in a plurality of (more than one) inductance coils countermeasure set each other of (or closely installing) on the same solid material.
Summary of the invention
The utility model provides a kind of reduction electromagnetic induction radiated interference device, installs the magnetic conduction bar additional in the electromagnetic induction coil outside.Its principle is: when having alternating current to pass through on the inductor, around inductor, will form a circle magnetic field, because the variation of magnetic direction makes surface of the work produce electric current again, this electric current is heated surface of the work.The electromagnetic induction coil outside adds the magnetic conduction bar, thereby effectively reduces magnetic dispersion, the magnetic radiation of magnetic circuit, reach reduce the wastage, the jamproof purpose of raising work.
In order to solve the problems of the technologies described above, the utility model is able to solve through following technical proposals:
A kind of reduction electromagnetic induction radiated interference device comprises heating controller, and electromagnetic induction coil is arranged on the heating controller, and the magnetic conduction bar is equipped with in the outside of described electromagnetic induction coil.
As preferably, described magnetic conduction bar is high frequency magnetic conduction bar, intermediate frequency magnetic conduction bar, low frequency magnetic conduction bar or metal magnetic conducting bar.
As preferably, the cross section of described magnetic conduction bar is circular, oval or square.
As preferably, described magnetic conduction bar has one or more.
The utility model is because the electromagnetic induction coil outside adds the magnetic conduction bar, thereby effectively reduces magnetic dispersion, the magnetic radiation of magnetic circuit, reach reduce the wastage, the jamproof purpose of raising work.
Description of drawings
Fig. 1 is a kind of structural representation that reduces electromagnetic induction radiated interference device of the described preferred embodiment of the utility model.
Embodiment
The utility model is described in further detail with embodiment below in conjunction with accompanying drawing 1.
Embodiment
A kind of reduction electromagnetic induction radiated interference device, as shown in Figure 1: comprise heating controller 1, electromagnetic induction coil 2 is arranged on the heating controller 1, a magnetic conduction bar 3 is equipped with in the outside of electromagnetic induction coil 2, and magnetic conduction bar 3 is a high frequency magnetic conduction bar, and cross section is a rectangle.When having alternating current to pass through on the electromagnetic induction coil 2, around electromagnetic induction coil 2, will form a circle magnetic field, generally speaking; Each heating controller 1 is equipped with an electromagnetic induction coil 2, the equipment that a plurality of heating controllers 1 are installed in same equipment or close on, at this moment; Cause electromagnetic interference; Because the variation of magnetic direction makes equipment surface produce electric current again, this electric current is heated equipment surface.The outside of electromagnetic induction coil 2 adds magnetic conduction bar 3, thereby effectively reduces magnetic dispersion, the magnetic radiation of magnetic circuit, reach reduce the wastage, the jamproof purpose of raising work.
In a word, the above is merely the preferred embodiment of the utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
