For further offsetting electromagnetic radiation, and the consistency from top to bottom distribution consistent of said electric heating piece with the width of conducting strip.
To be applied to floor, wallboard or desktop etc. fashionable when electric hot plate, and for the generation that prevents to leak electricity and guarantee safe in utilizationly, the two sides of this low electromagnetic wave electric hot plate coat also and are sealed in the insulating barrier.Also can prevent when electric hot plate is immersed in the water, to leak electricity.
Further, for conveniently producing and reducing production costs, described two groups of electric heating pieces are made up of the charcoal slurry that prints or be coated on the said substrate.Said insulating barrier is suitable for preventing that this charcoal slurry from oxidation taking place, so its useful life is longer.
Further, said conducting strip is printing or stickup or is plated on the metal level on the said substrate.Therefore the resistance of conducting strip is lower, does not generate heat basically in use.
Further, said substrate comprises: glass cloth be coated on the up and down epoxy resin layer of two sides of this glass cloth, therefore, this substrate has higher mechanical strength and insulation property.
For having made conducting strip distribute far infrared, the printing far infrared is distributed material on the upper surface of conducting strip, and for example germanite powder (or other anion materials), carbon dust etc. distribute far material through heat absorption.
The technique effect that the present invention has: in the low electromagnetic wave electric hot plate of the present invention; Electric heating piece and conducting strip are corresponding up and down to distribute; And the current opposite in direction and the size of current of electric heating piece and conducting strip are consistent when using; The electromagnetic wave that produces in electric heating piece and the conducting strip is in the opposite direction and intensity is consistent, therefore is suitable for the electromagnetic radiation that cancels each other out, thereby significantly reduces the electromagenetic wave radiation of whole electric hot plate.The two sides of electric hot plate coat and are sealed in the insulating barrier, and be applied to fields such as floor, wallboard or desktop when this electric hot plate fashionable, can prevent the generation of leaking electricity and guarantee safe in utilization.Therefore, electrothermal plate structure of the present invention is simple, production cost is lower, be suitable for significantly reducing electromagenetic wave radiation, fail safe is higher and do not influence the heat efficiency.

For content of the present invention is more clearly understood, below basis specific embodiment and combine accompanying drawing, the present invention is done further detailed explanation, wherein
Fig. 1 is the Facad structure sketch map of the low electromagnetic wave electric hot plate among the embodiment;
Fig. 2 is the structure sketch map of the low electromagnetic wave electric hot plate of another kind among the embodiment;
Fig. 3 is the A-A cross-sectional view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is elaborated:
Like Fig. 1-3, the low electromagnetic wave electric hot plate of present embodiment comprises: substrate 1, be located at two groups of electric heating pieces 2 of substrate 1 upper surface and be located at substrate 1 lower surface and conducting strip 3 each electric heating piece corresponding distribution about in the of 2; One end of each electric heating piece 2 in first group of electric heating piece links to each other with the first electrode slice L, and an end of each electric heating piece 2 in second group of electric heating piece links to each other the first electrode slice L and second electrode slice N insulation with the second electrode slice N; The other end of each electric heating piece 2 in two groups of electric heating pieces is electrically connected with a corresponding up and down end of each conducting strip 3 respectively, and the other end of each conducting strip 3 is electrically connected.
The first electrode slice L is used to be connected interchange or DC power supply with the second electrode slice N during use.During work, electric current flows into first group of electric heating piece through the first electrode slice L, flows into second group of electric heating piece through conducting strip 3 then, flows out from the second electrode slice N at last.Electric heating piece 2 and conducting strip corresponding distribution about in the of 3; And the current opposite in direction and the size of current of electric heating piece 2 and conducting strip 3 are consistent when using; The electromagnetic wave that produces in electric heating piece 2 and the conducting strip 3 is in the opposite direction and intensity is consistent; Therefore be suitable for the electromagnetic radiation that cancels each other out, thereby significantly reduce the electromagenetic wave radiation of whole electric hot plate.
Be further to offset electromagnetic radiation, said electric heating piece 2 and consistency from top to bottom consistent with the width of conducting strip 3 distributes, and the width of electric heating piece 2 and conducting strip 3 evenly distributes to guarantee the electric current in the electric heating piece 2 between 2-5cm, and evenly generates heat, and guarantees the heat efficiency.
The two sides that should hang down the electromagnetic wave electric hot plate coat and are sealed in the insulating barrier, and this insulating barrier is epoxy resin or other capsulation materials.
Described two groups of electric heating pieces 2 are made up of the charcoal slurry that prints or be coated on the said substrate 1, also can adopt the heating sheet of other alloy materials or silica gel heating sheet to be pasted on the said substrate 1.
