Abstract
The utility model discloses an electromagnetic radiation resistant electromagnetic oven, which comprises a panel, a panel casing for placing the panel, a bottom casing, a coil disc inside the oven, a power cord inserted into a main board as well as a ferrite magnetic ring, wherein the tail end of the power cord is wound on the ferrite magnetic ring, so as to achieve the purpose of elimination of the transmission interference and electromagnetic radiation. The utility model has simple structure and low manufacturing cost, and ensures the electromagnetic oven to be safer, more environment-friendly and healthier if used.
Description
Technical field
The utility model belongs to the electromagentic furnace technology field, particularly the technical field of electromagnetic oven anti-electromagnetic radiation and Conduction Interference aspect.
Background technology
In existing industry technology, at the electromagnetic radiation and the total following several solutions of Conduction Interference problem of electromagnetic oven.
Solution one: part installs the metal radiation protective layer additional around the coil panel between face-piece, the following drain pan on the electromagnetic oven, and it mainly is to absorb the electromagnetic wave that electromagnetic oven leaks through coil panel by metal screen layer when working.
Solution two: cover one deck at the inner surface of electromagnetic oven shell or outer surface and inhale magnet assembly, this principle of device be when electromagnetic oven is worked, and the suction magnet assembly can absorb the electromagnetic energy that stove interior loop dish leaks and be converted into heat energy and dissipate, thereby reaches radiation protection.
Solution three: in electromagnetic oven, adorn a function element, the power line of electromagnetic oven and radiation absorption layer form a complete shield, electronic circuit generation electromagnetic radiation when shielding cover body inboard just can absorb with the shielding cover body, and discharges by the power line that connects the earth.
Solution four: form by housing, panel and stove interior loop dish, around the stove interior loop, arrange induction coil, the induction power supply output that other control section of the two ends of induction coil and electromagnetic oven is connected links to each other, after induction coil receives induced field, just will respond to magnetic energy automatically and change into induced voltage output, electromagnetic radiation be transformed from face.
In existing radiation protection electromagentic furnace, all ignored when electromagnetic oven work under the high-power current state, through the Conduction Interference of power line generation and the processing of radiation disturbance.In present solution, all there are problems such as locality, limitation, unstability.And too complicated in process of production, cost is higher is unfavorable for large-scale production, and anti-electromagnetic radiation, anti-Conduction Interference aspect treatment effect are relatively poor.Therefore when the utility model is intended to improve electromagnetic oven work through problems such as electromagnetic radiation that power line brought and Conduction Interference.
Summary of the invention
The purpose of this utility model is to remedy the deficiencies in the prior art, provides a kind of and solves when having electromagnetic oven work now through the Conduction Interference of power line generation and the anti-electromagnetic radiation electromagnetic oven of electromagnetic interference problem.
In order to reach the foregoing invention purpose, the utility model has adopted following technical scheme: a kind of anti-electromagnetic radiation electromagnetic oven, comprise panel, be used to put face-piece, drain pan, stove interior loop dish, power line and the circuit main board of panel, also comprise a ferrite bead, the terminal winding of described power line is plugged in described circuit main board after crossing ferrite bead.
The utility model installs a ferrite bead additional at the slotting tail place of electromagnetic oven power line especially, and power line is inserted two circles on the portion winding ferrite bead, makes it form an inductance.According to electromagnetic theory, any alternating current all can produce magnetic field.Because the coil panel in the electromagnetic oven is operated under the alternating current of 25KHz, this just makes it become the radiation disturbance source, after forming, the harassing and wrecking source rely on the route of transmission to radiate, the power line of all electromagnetic ovens does not adopt the coaxial cable of shielding not increase any Anti-Radiation Countermeasures at power line yet in the prior art, and this just makes power line form that antenna is gone out electromagenetic wave radiation and produce Conduction Interference by power line easily.Therefore, installing long ferrite bead additional at the slotting tail place of power line is carrying on the power line of interference its string, allow the power line by ferrite bead form an inductance, play the effect of two circle RF choke coils, so just can effectively suppress the Conduction Interference and the radiation disturbance that bring through power line, and eliminate image such as current break.Therefore, the utlity model has following beneficial effect: 1, the utility model anti-electromagnetic radiation electromagnetic oven, owing to install ferrite bead additional, can effectively suppress Conduction Interference and the radiation disturbance that brings through power line and eliminate current break and reduce harmonic wave in the circuit.2, the utility model anti-electromagnetic radiation electromagnetic oven has improved the locality, limitation, the unstability that exist in the present technology.3, the utility model anti-electromagnetic radiation electromagnetic oven, its suitable production in enormous quantities simple in structure, safe and reliable, cheap for manufacturing cost.
Below in conjunction with the drawings and specific embodiments the utility model is described in detail:
Description of drawings
Fig. 1 is the utility model STRUCTURE DECOMPOSITION schematic diagram.
The specific embodiment
As shown in the figure, a kind of anti-electromagnetic radiation electromagnetic oven described in the utility model comprises panel 1, face-piece 2, drain pan 8, stove coil panel 3, power line 4.Panel 1 is placed in face-piece 2 surfaces.Stove coil panel 3 is arranged between face-piece 2 and the drain pan 8, and is connected to power line 4 through mainboard 7.The end of power line 4 is equipped with a ferrite bead 5 above inserting tail 6, allows slotting tail 6 on the power line 4 at the mainboard 7 of pegging graft again behind two to three circles on the ferrite bead 5, so that it forms an inductance.Because the radiation disturbance source of electromagnetic oven is the coil panel 3 in the electromagnetic oven, the route of transmission is a power line 4, therefore on the power line 4 that carries interference, go here and there a ferrite bead 5, make it form an inductance, so just play the effect of two circle choke coils, reach and eliminate current break, minimizing harmonic wave, suppress the purpose of Conduction Interference and radiation disturbance.
