The invention discloses a refrigerator defrosting control method and device, and relates to the technical field of refrigerator defrosting. The refrigerator defrosting control device comprises a controller, a timing unit, a comparison unit, a detection unit and an electric heater, wherein the timing unit, the comparison unit, the detection unit and the electric heater are electrically connected tothe controller; the detection unit comprises a humidity sensor; the humidity sensor is installed at a refrigerator controlled compartment air return opening and monitors humidity data at the air return port in real time; the detection unit is used for receiving the humidity data at the controlled compartment air return opening and outputting humidity data information to the controller; and a gradient mapping relation between the compressor cumulative running time length T and the air return opening humidity value RH of the refrigerator defrosting triggering conditions is set. The method is ajudging method for detecting the air humidity at the controlled compartment air return opening, the degree of frosting of an evaporator can be more accurately predicted, in-time and effective defrosting is carried out, and the advantages of energy saving and consumption reduction are achieved.
Description
technical field [0001] The invention belongs to the technical field of defrosting of refrigerators, and in particular relates to a method and device for controlling defrosting of refrigerators. Background technique [0002] Frost on the evaporator will seriously affect the heat exchange capacity of the evaporator. Conventional defrosting control is generally to control the defrosting of the heater according to a specific time, for example, according to the accumulated running time of the compressor or the door opening time reaching the preset value, start Heater defrost. This kind of defrosting control does not defrost according to the actual frosting situation. According to the different usage environments of the refrigerator, when the accumulative running time of the compressor or the door opening time is the same, the degree of frosting on the evaporator will be different. Do not start defrosting when defrosting should not be used to waste electricity. [0003] A refri...
