WIPO Patent Application WO/2017/217696
Kind Code:
Disclosed is a planar heating element for a rice cooker. The planar heating element of the present invention comprises a first substrate formed on the inside of a rice cooker and having a first pattern, which is heated by power supplied from a power supply unit, printed with a conductive ink on one surface thereof so as to be heated by power supply unit supplied from the outside, a second substrate which is heated by the power supplied from the power supply unit on one surface thereof and on which a second pattern having the same shape as the pattern of the first substrate is printed with a conductive ink, and an adhesive layer for adhering the first substrate and the second substrate so that the patterns of the first substrate and the second substrate overlap each other vertically. Accordingly, the heat generation performance of the present invention is superior to that of the conventional heating element and a reverse current patterning technology is applied thereto such that the current flows in opposite directions on both sides of the substrate, and thus electromagnetic waves can be effectively shielded.
