  • Patent number: 6047554
    Abstract: The present invention relates to an optimum defrosting cycle method of an inverter refrigerator. In the past, a defrosting cycle setting method for a conventional refrigerator with which a defrosting operation was carried out when the operation time of a compressor reaches a certain amount of time(e.g. 7 hours) by simply accumulating the operation time of the compressor. However, there have been drawbacks since the operation speed of a compressor varies for a high speed, mid speed, and low speed according to the surrounding condition when the conventional method is applied to the inverter refrigerator, it is not relevant to set the defrosting cycle by simply accumulating the operation time.
