The electromagnetic wire coil comprises a wire coil bracket, coils and magnetic strips, wherein, the coils comprise outer ring coils and inner ring coils which are fixed on the wire coil bracket, the magnetic strips comprise outer circle magnetic strips and inner circle magnetic strips which are arranged to be corresponding to the coils, and the outer circle magnetic strips and the inner circle magnetic strips are respectively distributed in a radiating type. The utility model is characterized in that the outer circle magnetic strips and the inner circle magnetic strips are mutually staggered in the radiating type distribution direction. The electromagnetic wire coil is provided with inner and outer ring heating wave crests, and a wider heating ring band is formed between the heating wave crests, therefore, the heating is evener.

Description

Electromagnetic oven electromagnetic wire dish

Technical field

The utility model relates to the electromagnetism drum that a kind of electromagnetic oven and similar device are used.

Background technology

Existing electromagnetic oven mainly is made up of drum support, magnetic stripe, coil with the electromagnetic wire dish, the arrangement of magnetic stripe under coil in two kinds of situation: the first is placed in one group of magnetic stripe that distributes radially under the coil; It two is two groups of magnetic stripes that radial distributes under coil, form outer ring magnetic stripe and inner ring magnetic stripe, wherein align with each root of magnetic stripe of inner ring and be arranged on the same radial direction in the outer ring, form inside and outside two discontinuous heating endless belt, the bubble that produces from the bottom of a pan, back of seething with excitement as can be seen, the heat that inside and outside heating collar respectively has part (mainly being below magnetic stripe) to produce is too concentrated, it is intensive heating ring region bubble to occur, the phenomenon that other regional bubble is few heats even inadequately.

As everyone knows, the relative air of the magnetic stripe of magnetic conduction is the good conductor of the magnetic line of force, and magnetic stripe main effect in the electromagnetism drum is exactly the bottom of a pan of the magnetic line of force being gathered back guiding pan, produces eddy current heating pan, can reduce the electromagnetic interference to surrounding environment simultaneously.Can find out that with electromagnetic induction wire coil emulation and result of the test the magnetic field distribution in the bottom of a pan has following characteristics to the electromagnetic oven with outer ring magnetic stripe and inner ring magnetic stripe: the intermediate magnetic induction of heating endless belt is the strongest, forms crest, and is weakened gradually to both sides by the centre; Magnetic stripe place magnetic field intensity is the strongest on the heating endless belt, forms crest, and is weakened gradually to both sides by the centre; Two heating crests will can be formed behind coiled two parts heating spool rest between heater coil, if outer ring magnetic stripe and the alignment of inner ring magnetic stripe are arranged, promptly align at center line, the local electric and magnetic oscillation of heating region is obviously bigger, the corresponding increase of electromagnetic noise, it is nearer at interval that each magnetic stripe is subjected to the locus limitation simultaneously, produces the phase mutual interference between the magnetic line of force, and heats is also had negative effect.

Summary of the invention

The purpose of this utility model is to provide a kind of electromagnetic oven electromagnetic wire dish, has inner and outer rings heating crest, forms the heating endless belt of broad between the heating crest, heats more even.

A kind of electromagnetic oven electromagnetic wire dish, comprise drum support, coil, magnetic stripe, coil comprises outer shroud coil and the inner loop-line circle that is fixed on the drum support, magnetic stripe comprises the outer ring magnetic stripe and the inner ring magnetic stripe of corresponding setting with coil, outer ring magnetic stripe and inner ring magnetic stripe radially distribute respectively, it is characterized in that the interlaced arrangement on radial distribution arrangement of described inner ring magnetic stripe and outer ring magnetic stripe.

The shape of described inner ring magnetic stripe and outer ring magnetic stripe can be a strip.

The two ends of inner ring magnetic stripe and outer ring magnetic stripe all have the turning of the corresponding coil of envelope, and magnetic stripe integral body is U.，

The distal end of inner ring magnetic stripe and outer ring magnetic stripe has the turning of the corresponding coil of envelope, and magnetic stripe integral body is L-shaped.

The utility model electromagnetic oven electromagnetic wire dish, be distributed in inner ring magnetic stripe and outer ring magnetic stripe under the drum support, the magnetic stripe arrangement mode is staggered, effective dispersed-heated crest, enlarged magnetic line of force distribution area, reduce the mutual interference between adjacent magnetic stripe simultaneously, make the magnetic line of force in the whole winding dish guiding the bottom of a pan be evenly distributed, heat endless belt and widen, therefore heating is more even.

Compare by test and existing electromagnetism drum, the electromagnetism drum heating back bubble zonation width of the technical program increases more than 6%, can reduce more than the noise 0.5dB that local high vibration brings, disperseed to concentrate on the drum heat that distributes, avoid local overheating to cause potential safety hazard, also improved the reliability of electromagnetic oven.

Embodiment

Below in conjunction with accompanying drawing the utility model is further described:

As implement the electromagnetism drum of prior art shown in the illustration 1, will produce the heating crest of 8 magnetic stripe tops, the local electric and magnetic oscillation of these heating regions of concentrating is obviously bigger, the corresponding increase of electromagnetic noise, simultaneously, it is nearer be separated by by the influence of locus limitation at this scheme Internal and external cycle magnetic conduction bar, produces the phase mutual interference between the magnetic line of force, and heats is produced certain influence.

As implement shown in the illustration 3, a kind of electromagnetic oven electromagnetic wire dish, comprise drum support 3, coil, magnetic stripe, coil comprises outer shroud coil 4 and the inner loop-line circle 5 that is fixed on the drum support 3, outer shroud coil 4 and inner loop-line circle 5 are connected in the circuit, magnetic stripe comprises the outer ring magnetic stripe 1 and the inner ring magnetic stripe 2 of corresponding setting with coil, the two ends of inner ring magnetic stripe 2 and outer ring magnetic stripe 1 have the turning of the corresponding coil of envelope, the magnetic stripe overall U-shaped, outer ring magnetic stripe 1 and inner ring magnetic stripe 2 radially distribute respectively, described inner ring magnetic stripe 2 and outer ring magnetic stripe 1 interlaced arrangement on radial distribution arrangement.

Test by experiment can effectively disperse the heating crest, can effectively reduce the mutual interference in magnetic field between the adjacent magnetic conduction bar of Internal and external cycle, and the magnetic line of force in the whole winding dish guiding the bottom of a pan is more evenly distributed, and reaches that the heating endless belt is wideer, the effect of homogeneous heating.

The magnetic stripe shape that distributes radially in the technical program can also be as the strip of Fig. 4 or L shaped as Fig. 6, can obtain better technical effect equally.

The electromagnetism drum of present embodiment, its described outer shroud coil 4 and inner loop-line circle 5 also can be entwined by wire harness respectively at interval, and radiating effect is better like this.

The electromagnetic oven of present embodiment electromagnetic wire dish; comprise outer shroud coil 4 and inner loop-line circle 5 as Fig. 2; it is the minimum unit structure; the also interior increase coil of the periphery of ring coil 4 or inner loop-line circle 5 outside; in conjunction with Fig. 2,3; obtain for those skilled in the art can rationally infer, also belong to the protection range of this patent.
