Title:
REFRIGERATOR PLANAR HEATING ELEMENT AND HEATING CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2018/048066
Kind Code:
A1
Abstract:
A refrigerator planar heating element is disclosed. According to the present invention, a refrigerator planar heating element arranged inside the refrigerator and radiating heat by means of a power unit applied from the outside comprises a defrosting planar heating element comprising: a first substrate having one surface on which a first pattern for radiating heat by the power supplied from the power unit is printed with conductive ink; a second substrate having one surface on which a second pattern for radiating heat by the power supplied from the power unit and having the same form as the pattern of the first substrate is printed with conductive ink; and an adhesive layer for performing bonding such that the patterns of the first substrate and the second substrate are overlapped in a vertical direction, and thus the present invention has heating performance more excellent than that of conventional heating elements, and applies an inverse current patterning technique so as to make a current flow in opposite directions at both surfaces of a substrate, thereby effectively shielding electromagnetic waves.
