Description
Technical field
The utility model relates to a kind of safety electromagnetic stove, specially refers to a kind of electromagnetic oven of anti-electromagnetic radiation.
Background technology
Since electromagnetic oven comes out, because that it has is convenient, healthy, safety and advantage such as energy-conservation, by more and more utilizations widely; Because working principle of induction cooker is to come work by the electric current eddy current after producing high-frequency alternating magnetic field by magnet exciting coil, it inevitably exists the common fault of modern household electrical appliances---electromagnetic radiation, thereby may user's health be exerted an influence but simultaneously.In today that the electromagnetic radiation of household electrical appliance also more and more causes people's attention to the influence of surrounding environment, development has also become the problem that electromagnetic oven production firm must consider with the matching used anti-electromagnetic radiation device of electromagnetic oven.
China Patent No. is 97212768.2, Granted publication day is on March 17th, 1999, invention and created name is " set up metal frame and shield electromagnetic electromagnetic oven ", this utility model patent discloses a kind of antimagnetic shield device of electromagnetic oven, comprise body of heater and magnet exciting coil, a metallic shield frame is set up in the periphery of magnet exciting coil in electromagnetic oven.Adopt such metallic shield frame antimagnetic shield parts, can shield mortar leakage field that end periphery on the magnet exciting coil reveals preferably promptly, but can't shield for " leakage field " of magnet exciting coil sidepiece and lower periphery; Moreover, to sidepiece and the lower periphery of human body and electric elements influential " leakage field " overwhelming majority from magnet exciting coil.In addition, owing to the metallic shield frame cross section that the utility model adopted is
The structure of type also masks end periphery on the magnet exciting coil to heating the useful part magnetic line of force, thereby has reduced the utilization ratio of the electromagnetism that magnet exciting coil produced.
China Patent No. is 200520034113.X, Granted publication day is to say July 5 in 2006, invention and created name is " a kind of electromagnetic oven that has the electromagnetic wave radiation shielding device ", this utility model patent discloses a kind of antimagnetic shield device of electromagnetic oven, comprise coil panel, it is characterized in that: also include a plate-like metallic shield box, this metallic shield box comprises bottom surface and side, and coil panel is placed in the metallic shield box.Adopt such metallic shield frame antimagnetic shield parts, " leakage field " of shielded coil dish lower end and sidepiece leakage preferably, but can't shield for " leakage field " of coil panel top periphery; In addition, coil panel lower end integral body shielded also there is no need because to human body and the disadvantageous leakage field of electric elements mainly from periphery position, coil panel lower end, such shielding construction has also increased the processing cost of electromagnetic oven.
Summary of the invention
At the deficiencies in the prior art, the utility model proposes a kind of simple in structure, processing cost is low, anti-electromagnetic radiation is effective electromagnetic oven.
In order to achieve the above object, the utility model is by the following technical solutions:
A kind of electromagnetic oven of anti-electromagnetic radiation, comprise body of heater 1 and magnet exciting coil 2, magnet exciting coil 2 is fixed in the body of heater 1, it is characterized in that: also comprise a metallic shield ring 4, the cross section of described metallic shield ring 4 is flat and is fixed in the body of heater 1, and described magnet exciting coil 2 is positioned at metallic shield ring 4.
The height of a little higher than magnet exciting coil 2 of the height of above-mentioned metallic shield ring 4, described magnet exciting coil 2 is positioned at metallic shield ring 4, thereby makes the electromagnetic energy that produces in magnet exciting coil 2 neighborings effectively be masked by metallic shield ring 4.
Above-mentioned metallic shield ring 4 is made for aluminium or nickel alloy.
The inwall of above-mentioned metallic shield ring 4 can be smooth surface; Can or be rule surfaces such as waveform or zigzag also, can increase the area of absorption of metallic shield ring 4 inwalls and reflected electromagnetic like this, thereby make metallic shield ring 4 anti-electromagnetic radiation better effects if for rough irregular surface.
The upper end of above-mentioned metallic shield ring 4 radially can be provided with the last annular edge 41 of outside protrusion, be used for shielding the electromagnetism of revealing to magnet exciting coil 2 peripheries from magnet exciting coil 2 tops, though the electromagnetism that reveal to magnet exciting coil 2 peripheries on magnet exciting coil 2 tops can be realized by the height that increases metallic shield ring 4, but do the volume that can increase electromagnetic oven like this, also increase the production cost of electromagnetic oven; Annular edge 41 on can being disposed radially also that on projecting inward annular edge 44 replaces outwards protruding in the upper end of metallic shield ring 4, but when projecting inward last annular edge 44 is preventing electromagnetic exposure, also can reduce the utilization rate of the useful electromagnetism that magnet exciting coil 2 produced.
Above-mentioned metallic shield ring 4 bottoms radially also can be provided with the following annular edge 43 of outside protrusion, are used for shielding the electromagnetism of revealing to magnet exciting coil 2 peripheries from magnet exciting coil 2 bottoms; Also can be disposed radially to projecting inward following annular edge 42 and replace the outwards following annular edge 43 of protrusion in the bottom of metallic shield ring 4.
Because the utility model adopts technique scheme, compare with prior art, have following beneficial effect: (1) is because technical solution adopted in the utility model can be with the electromagnetic shielding of magnet exciting coil sidepiece and lower periphery leakage, compare the anti-electromagnetic radiation better effects if so can only shield the electromagnetism of sidepiece leakage with prior art.(2) because the utility model adopts only masking human body and disadvantageous that a part of electromagnetism of electric elements of technical scheme, to heating the not shielding of useful electromagnetism, thereby, with the mask frame that prior art is adopted the shielding that electromagnetism does not add differentiation is compared, the utility model is higher to the utilization ratio of the electromagnetism that magnet exciting coil produced.(3) with adopt the metallic shield box to shield to compare, production cost of the present utility model is lower.
The utility model is applicable to the shielding of all kinds of electromagnetic ovens.
