Problems solved by technology

However, this method cannot shield all electromagnetic radiation, and the metal shielding layer compounded on the surface of the heating plate will affect the transmission of heat, reduce thermal efficiency, and cause the heating effect of the heating plate to deteriorate
In addition, the area of ​​the heating plate is large, and a large number of metal shielding layers are used, which will lead to an increase in cost

Embodiment Construction

[0015] The following examples are further explanations and supplements to the present invention, and do not constitute any limitation to the present invention.

[0016] Such as figure 1 , figure 2 As shown, the heating plate without electromagnetic radiation of the present invention is composed of an upper insulating plate 10, an intermediate insulating plate 20, and a lower insulating plate 30, and the upper and lower sides of the intermediate insulating plate 20 are respectively provided with heating wires for revolving wiring. 40 and the wire 50, and the positions of the heating wire 40 and the wire 50 are corresponding, and the heating wire 40 and the wire 50 are connected with the external power wire 60 to form a loop. When the external power line 60 is powered on, the heating wire 40 and the wire 50 are energized to generate electromagnetic fields with opposite directions and equal magnitudes, and the electromagnetic fields cancel each other out so that the total amoun...

Abstract

The invention relates to an electromagnetic-radiation-free heating plate comprising an upper insulating plate, a middle insulating plate and a lower insulating plate which are composited. A heating wire and a lead which are rotationally routed are respectively arranged on an upper surface and a lower surface of the middle insulating plate, the heating wire is opposite to the lead, one end of the heating wire is connected with one end of the lead, the other end of the heating wire is connected with an external power line, and the other end of the lead is connected with the external power line. When the power is on, loop current is formed between the heating wire and the lead, and electromagnetic fields with opposite direction and equal magnitude are generated, so that electromagnetic radiation respectively generated by the heating wire and the lead is offset, total electromagnetic radiation quantity is zero, and no electromagnetic radiation harm to human bodies is caused. With the non-electromagnetic radiating heating plate, the electromagnetic radiation generated when the heating board is heating can be effectively eliminated, human body can be protected, and cost for shielding layers can be reduced.

Description

【Technical field】 [0001] The invention relates to a heating plate, in particular to a heating plate without electromagnetic radiation with functions of health care, physical therapy and heating. 【Background technique】 [0002] With the development of modern science and technology, heating panels are becoming more and more popular, and they are widely used in health care and heating, for example, in electric steam rooms or electric heating floors, which provide great convenience for people's lives. The heating plate provides heating and health care functions for people by converting electrical energy into heat energy. When it is powered on, there is current passing through the heating wire, and electromagnetic radiation will be generated when the current passes through. As we all know, long-term electromagnetic radiation is harmful to the human body. It will affect the circulation, immunity, reproduction and metabolic functions of the human body, lead to blood, lymph and cell...
