Description

technical field

[0001] The present invention relates to a defrosting heater for a refrigerator with the following effects: by setting different winding amounts of heating wires along the length of the heater, the defrosting process for removing frost attached to the evaporator can be effectively performed. Background technique

[0002] The cold air in the refrigerator is produced by the contact of air with the evaporator. In addition, air circulates inside the refrigerator, and moisture contained in the air adheres to the surface of the evaporator, which is relatively cold, to form frost. If the above-mentioned frost is formed as ice having a certain thickness or more, the heat exchange performance of the evaporator is hindered, so it is necessary to perform a defrosting process at a certain time period. Generally, the above-mentioned defrosting process is performed by generating heat from a heater provided on the evaporator.
