Description

A kind of planar heating element of low electromagnetic

Technical field

The utility model relates to a kind of planar heating element, particularly a kind of planar heating element of low electromagnetic.

Background technology

Planar heat producing body is the planar body that can generate heat after a kind of energising, its have the heating and area of dissipation big, conduct heat evenly, heat efficiency height, characteristics such as easy to use, be widely used in the foot-bathing bucket of sauna house, gymnasium, xeothermic formula, product such as floor heating, daily household electrical appliance, in use, the heat that sends by planar heat producing body heats.Because the electric current of existing product inside generally all is unidirectional, relatively is easy to generate electromagnetic field, adopts curvilinear structures also can't comprehensively prevent; And generally all the single face ink printing on technology and structure, carbon fiber is arranged or is arranged as requested with other conductive exothermal materials, as the Chinese utility model patent (patent No.: 200720051633.0) disclose a kind of plane heater, this plane heating element structure includes carbon fiber, carbon fiber becomes parallel through permutation, have the insulating thin layer of driving fit on the carbon fiber, the two ends of carbon fiber are provided with parallel pole; Described carbon fiber becomes set a distance to be arranged in parallel.This plane heater has advantages such as heating area is big, and reelability is strong.But the plane heater of this structure also exists must shortcoming, because in the heater of the plane of this structure, has only pair of electrodes, therefore the sense of current on the carbon fiber all is same direction, according to electromagnetic laws, the magnetic direction that same direction produces is identical, therefore tend to produce bigger electromagnetic field when adopting the plane heater heating of this mechanism, produce electromagnetic radiation, people are as being in for a long time under this environment, tend to people's health is exerted an influence, particularly be easy to health is worked the mischief for pregnant woman and children.

The utility model content

At above-mentioned the deficiencies in the prior art and shortcoming, the purpose of this utility model is to invent a kind of new production process and product structure, when reducing heating board surface electrical magnetic field intensity, dwindled the surperficial temperature difference greatly, a kind of planar heating element of low electromagnetic is provided.

Embodiment of the present utility model is achieved through the following technical solutions:

A kind of planar heating element of low electromagnetic.Described heater comprises and is positioned at upper surface first insulating barrier and is positioned at lower surface the 3rd insulating barrier, first conductive heating layer and second conductive heating layer are set between first insulating barrier and the 3rd insulating barrier, first conductive heating layer is consistent with the shape of second conductive heating layer, second insulating barrier is set between the adjacent conductive heating layer, is electrically connected between the adjacent conductive heating layer.

Electrode is set on conductive heating layer, utilizes conductor to be electrically connected between the electrode of adjacent two layers conductive heating layer.The shape unanimity of conductive heating layer, current opposite in direction.The shape of conductive heating layer can be designed to arbitrary shape.Described insulating barrier also can be flexible insulating layer.Described conductive heating unit also can adopt the far-infrared material of low electromagnetic.On electrode, utilize wire connection controller.The insulating barrier number of plies and thickness can be adjusted, and to meet basic insulation, reinforced insulation etc. are so that adapt to different occasions.

The utility model has the advantages that:

Because in technique scheme, the electrode of same direction one end of first conductive heating layer and second conductive heating layer is connected with power supply, and the electrode of first conductive heating layer and the unidirectional other end of second conductive heating layer is connected by conductor, therefore when these two heating layer energisings, these two conductive heating layers can form the loop, the electric current meeting flows to the other end from power supply one end of a heater earlier, flow back to power supply one end at the other end through another heater, therefore the sense of current on first conductive heating unit and second conductive heating unit is opposite.So according to electromagnetic laws, the magnetic direction that first conductive heating unit and second conductive heating unit produce also is opposite, and first conductive heating layer consistent with the shape of second conductive heating layer, therefore can cancel out each other in the magnetic field that produces of first conductive heating unit and second conductive heating unit.The surface of this planar heating element does not almost have electromagnetic radiation, so the utility model can not work the mischief to human body, is a kind of planar heating element of low electromagnetic of health environment-friendly.
