Problems solved by technology

[0004] However, the current flow at the power input point of the existing plate-shaped heating element is relatively large, so local overheating occurs at the power input point, and the heat generated at the far position between the power input point is relatively low, Therefore, there is a problem of non-uniform heating over the entire surface of the plate-shaped heating element.
Therefore, it is difficult to apply the existing plate-shaped heating element to equipment requiring uniform heating

Abstract

Disclosed herein is a plane heater that generates heat by using graphene or the like as the conductive heat generation material thereof. The plane heater includes: a first electrode configured to be connected to one pole of a power source; and a second electrode configured to be connected to the other pole of the power source; and wherein the intervals between at least some portions of the first electrode and the second electrode are determined such that a plurality of electric circuits formed by the first electrode, the heat generation material, and the second electrode can have the theoretically same resistance, wherein a bridge is disposed to serve as a medium for a current flow between the first electrode and the second electrode. According to the plate heater, current uniformly flowsin a heating substance between the two electrodes for generating uniform resistance heat, thereby improving applicability of the plate heater.

Description

Technical field [0001] The present invention relates to a plate-shaped heating element using graphene or the like as a conductive heating substance. Background technique [0002] Generally, the plate-shaped heating element can be applied to the glass surface of refrigerated display cabinets, window systems, automobile glass surfaces or gaskets, bathroom glass, rice cookers, and the like. [0003] Generally, a plate-shaped heating element is coated with a conductive heating material such as graphene on a non-conductor substrate, and is formed, for example, in a structure in which a first electrode as a + electrode and a second electrode as a-electrode are combined. In addition, if a DC or AC voltage is applied to the first electrode and the second electrode, current flows through the conductive heat generating material to generate resistance heat. [0004] However, the current flow at the power input point of the conventional plate-shaped heating element is relatively large, so local...
