manufacture example 1

[0272] When the magnetic field was measured at the electrode part of Production Example 1, the value was too high to be measured, and the magnetic field value measured at the center part was 10.67mG. In order to reduce this value, Manufacturing Example 2 was used for measurement.

[0273] Table 3 shows the measurement results of the heating film produced in Production Example 2.

[0275]

[0276] According to the results of Production Example 2, the measured values ​​at the electrode part and the center part were 0.59mG and 0.478mG, respectively, and the values ​​were significantly reduced. Manufacturing Example 3 was then measured for further reduction.

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.

Description

technical field [0001] The present invention relates to a flat heater, more specifically, to a flat heater for a refrigerator and a heating control method thereof, which is used in a refrigerator that needs to be heated at a specified temperature for defrosting or dew condensation prevention by using printed electronic technology. Flat heater for heating source. Background technique [0002] Generally speaking, the surface of the evaporator of the refrigerator will form frost due to the moisture entering the interior when the refrigerator is opened and closed. The formation of frost will cause the evaporator to fail to function normally and make it difficult to adjust the temperature of the refrigerator. produce adverse effects. Therefore, for periodic defrosting, a defrosting heater is provided around the evaporator of the refrigerator. [0003] The defrosting heater is activated under the control of the control unit to generate heat to melt frost. [0004] That is to sa...
