Abstract
The utility model provides a high-frequency induction electromagnetic heating device, which is composed of a power supply, an oscillation and filter circuit, a high-frequency power amplifying circuit, a heating coil, etc. The utility model is characterized in that the heating coil is composed of at least more than two sets of coils in the same shape; the coils can generate electromagnetic fields in the same direction in a working area so as to enhance the heating effects; whereas electromagnetic fields in the opposite direction can be generated outside the working area, and accordingly, the electromagnetic fields can be weakened mutually, so that the radiation effect on the environment can be reduced, and the problems of electromagnetic wave leakage and shielding can be effectively solved. The utility model has the advantages of simple structure, safe utilization, low cost, high work efficiency, etc.
Description
The utility model relates to electromagnetic heater, particularly a kind of high-frequency induction electromagnetic heater.
The general single coil structure that adopts in the common high-frequency heating apparatus, usually there is the electromagnetic-wave leakage problem in actual applications, along with the increase of power and the rising of frequency, leak and shield caused problem and more and more can not be ignored, this personal safety and heat efficiency thereof to the operator all can cause direct influence.In addition, for the difform heated work pieces that is subjected to, also need difform heater coil.In order to increase work efficiency, must be improved existing obsolete equipment.Yet no matter present this legacy equipment does not still satisfy the requirement of modern production technology on the efficient far away from function, will be replaced with new equipment.
The purpose of this utility model provides and a kind ofly can effectively solve electromagnetic-wave leakage, can solve the shielding problem again simultaneously, enhances productivity and the heat efficiency, reduces radiation, guarantees a kind of high-frequency induction electromagnetic heater of personal safety.
The purpose of this utility model is achieved by the following scheme: this heater comprises formations such as power supply, vibration and filter circuit, high-frequency power amplifying circuit and heater coil, wherein said heater coil has at least two groups of above identical shaped coils to constitute, this coil can produce the electromagnetic field of equidirectional in the working region, to strengthen its heats, outside the working region, then produce rightabout electromagnetic field, thereby reduce radiation effects to the external world with mutual weakening electromagnetic field.
The utility model is compared with the prior art, and by the sine-wave current by 280KHZ (0,15A) respectively to unicoil and twin coil, unicoil adopts 1.2mm enamelled wire close around 40 circles, circle footpath 50mm; Adopt 1.2mm enamelled wire close with twin coil around 20 circles, circle footpath 50mm, two coils are to be connected in series, to unicoil and twin coil carries out radially or axial magnetic induction test, both under equal conditions test respectively, and the result who measures shows, its unicoil induction is big, can light a bulb, and the induction of twin coil almost approaches zero, lamp does not work.This is explanation just, and the utility model then can not only strengthen the efficiency of heating surface by changing the composition structure of heater coil, more can effectively solve electromagnetic-wave leakage and shielding problem etc.Have simple in structurely, safe and reliable simultaneously, cost is low, advantages such as operating efficiency height.
Below in conjunction with accompanying drawing the utility model is illustrated.
Fig. 1 is a circuit structure diagram of the present utility model;
Fig. 2 is two coil configuration figure of the present utility model;
Fig. 3 is that of the present utility model another implemented illustration.
As shown in Figure 1: this heater is by power supply, vibration and filter circuit, high frequency Power amplification circuit and heater coil and capacitor C consist of, wherein said power supply, shake Swing and filter circuit, high-frequency power amplifying circuit are conventional known technology, available This functional circuit replaces arbitrarily. Main feature of the present utility model is, its heater wire Circle adopts two groups of above identical shaped coil series connection to consist of, and it is satisfied in the workspace Produce the electromagnetic field of equidirectional in the territory, to strengthen heating effect, enhance productivity. Outside the working region, then produce rightabout electromagnetic field, thereby cut to reach mutually The purpose in light current magnetic field reduces the radiation effects to the external world.
Embodiment: with two solenoid coils or two solenoid coils the cylinder metal object is heated, as shown in Figure 2, the electromagnetic field direction that A, B coil produce to external world is just opposite, but the electromagnetic field of coil inside is played the effect that strengthens each other.As a same reason, as shown in Figure 3: the B coil internally all plays a part to add strong-electromagnetic field to A, C coil and C coil to the BD coil, and to external world, AC is opposite each other with the electromagnetic field that the BD coil produces, that is to say the purpose that has reached mutual weakening electromagnetic field, thereby guarantee handling safety.
Claims (2)
1, a kind of high-frequency induction electromagnetic heater is made of power supply, vibration and filter circuit, high-frequency power amplifying circuit and heater coil etc., it is characterized in that: said heater coil has at least two groups of above identical shaped coils to connect formation.
2, high-frequency induction electromagnetic heater according to claim 1, it is characterized in that: the twin coil of being made up of LA and LB can produce the electromagnetic field of equidirectional in the working region, to strengthen its heats, outside the working region, then produce rightabout electromagnetic field, reduce radiation effects to the external world with mutual weakening electromagnetic field.
