NOVELTY - The utility model claims a defrosting control device of refrigerator, relating to the technical field of refrigerator. The utility model comprises an evaporator and a main control board; the surface of the evaporator is coated with graphene coating; the graphene coating thickness is 20 m to 30 m; the evaporator pipeline inlet is connected with a first electrode; the evaporator pipeline outlet is connected with a second electrode; the input end of the first electrode and the second electrode are electrically connected with the main control board; the output end of the first electrode and the second electrode are connected with the graphene coating; the pipelines at the inlets and outlets at the two ends of the evaporator are connected with insulating pipelines. The utility model uses graphene material with good heat transfer performance as heat transfer medium and heating source; because the heating source and the frost layer are directly contact, using heat conduction to transfer heat; at the same time, because the graphene is heat good conductor, the defrosting speed is fast; In addition, because the heating source and the frost layer contact directly, it does not need intermediate medium to indirectly heat transfer; the utilization rate of the energy is high; the whole energy consumption of the refrigerator is greatly reduced.
