<P>PROBLEM TO BE SOLVED: To provide a refrigerator which easily estimates even a failure which has been difficult to be analyzed in the past by arbitrarily setting an acquisition interval of necessary operation information and storing it. <P>SOLUTION: The refrigerator includes a controller having a readable/writable memory on a substrate body equipped with a main microcomputer where the memory stores a detected value of each sensor, a control status value, a control count value, or maintenance support data as failure detection information in the refrigerator whenever a prescribed period of time elapses. The refrigerator also includes a maintenance support function which stores the newest data in place of the oldest data when the data exceed a size-fixed maintenance support data storage region, thereby discarding the oldest data. In addition, the refrigerator supports storage timing for investigation in addition to predetermined storage timing for maintenance support data, and stores maintenance support data at the storage timing for investigation if the storage timing for investigation is set. <P>COPYRIGHT: (C)2013,JPO&INPIT |
