[embodiment]
The following example is to further explanation of the present invention and replenishes, the present invention is not constituted any limitation.
The combined type Electric radiant Heating Film of low electromagnetic of the present invention is applicable to that all are the electric heating product of heating source with Electric radiant Heating Film 10.
Consult Fig. 1～Fig. 4; The combined type Electric radiant Heating Film of low electromagnetic of the present invention comprises Electric radiant Heating Film 10, screen 20 and lead 30; Said screen 20 is used to shield the low frequency electromagnetic radiation that Electric radiant Heating Film 10 is sent, and said lead 30 is used to connect Electric radiant Heating Film 10 and external power source.
Embodiment 1
As shown in Figure 1, said lead 30 is connected with Electric radiant Heating Film 10 in known manner, and it is Electric radiant Heating Film 10 power supplies through connecting outside 220V power supply.End near power supply terminal on the said lead 30 is provided with magnet ring 31, and this magnet ring 31 is used for filtering the low frequency clutter of external power source, prevents that the low frequency clutter from causing interference to Electric radiant Heating Film 10, makes the Electric radiant Heating Film heating property more stable.Said magnet ring 31 can be the magnetic powder core magnet ring, also can be ferrite bead or coiling magnet ring, in the present embodiment, and preferred ferrite soft magnetic magnet ring.With before Electric radiant Heating Film 20 is fixedly connected, select for use magnet ring 31 internal diameters to be slightly larger than the magnet ring of lead 30 external diameters at lead 30, this magnet ring 31 is enclosed within lead 30 outsides, and makes it, to reach better anti-electromagnetic interference effect near the wherein end in lead 30 links.The heat-shrinkable T bush that then internal diameter and magnet ring 31 external diameters is complementary is sleeved on the lead, with air-heater or thermal contraction machine heat hot Heat-Shrinkable Tubings, heat-shrinkable T bush is shunk and magnet ring is fixed on the lead, in known manner lead 30 is connected with Electric radiant Heating Film 10 again.
As shown in Figure 1, said Electric radiant Heating Film 10 can be any in the known Electric radiant Heating Film 10, and in the present embodiment, this Electric radiant Heating Film 10 is the translucent polyester film.The outer surface of said Electric radiant Heating Film 10 outside radiated electromagnetic wave one sides is a upper surface, and its opposite side is a lower surface.Said screen 20 is compound in the upper surface of Electric radiant Heating Film 10.Said screen 20 is a permalloy film, and it can be the iron nickel alloy film of high magnetic permeability, also can be sendust film or amorphous cobalt base alloy film, in the present embodiment, and preferred iron nickel alloy film.Said screen 20 is compound in Electric radiant Heating Film 10 upper surfaces, and through high-temperature-resistant adhesive the edge of screen 20 and Electric radiant Heating Film 10 is bonded together.
When combined type Electric radiant Heating Film 10 of the present invention was worked, after said magnet ring 31 filtered the low frequency clutter in the external power source, external power source gets into Electric radiant Heating Film 10 made Electric radiant Heating Film 10 generation infrared rays and certain wavelength be different from ultrared low-frequency electromagnetic wave.Said infrared ray sees through screen 20 radiation and forms thermal radiation to the space, directly heats the interior space.Because the magnetic permeability of said screen 20 is very high; Make screen 20 path that magnetic resistance is very low is provided for low-frequency electromagnetic wave; Make said low-frequency electromagnetic wave major part concentrate in the screen 20 and can't penetrate screen 20; Thereby when not influencing heats, reduce the electromagnetic radiations emission that Electric radiant Heating Film 10 is radiated the space greatly, greatly reduce the harm of electromagnetic radiation human body.
Experimental data shows that the magnetic flux density of the electromagnetic radiation that common electrical hotting mask 10 produces is 10
-5T (i.e. 100 milligauss), the magnetic flux density of the electromagnetic radiation that the combined type Electric radiant Heating Film 10 of low electromagnetic of the present invention produces is 3 * 10
-7In T (the i.e. 3 milligauss) scope.
Embodiment 2
The basic structure of present embodiment is with embodiment 1; Different is; Shown in Fig. 2～4, said screen 20 is compound in Electric radiant Heating Film 10 upper surfaces, and extends out to outside Electric radiant Heating Film 10 upper surfaces; The downward bending in the edge of screen 20 to Electric radiant Heating Film 10 lower surfaces are made the edge inclusion mutually of its edge and Electric radiant Heating Film 10, thereby screen 20 and Electric radiant Heating Film 10 are combined with each other.
Although through above embodiment invention is disclosed, protection scope of the present invention is not limited thereto, and is not departing under the condition of the present invention design, and the distortion that above each member is done, replacement etc. all will fall in the claim scope of the present invention.
