    • A self-diagnosing apparatus for self-diagnosing the operating state of a refrigerator and indicating the necessity of a remedy if an abnormality is present. First, a plurality of quantities of state are measured and stored in a memory section (7) for a predetermined period. The quantities of state or a diagnostic operation value operated based on the quantities of state is then compared with a specified threshold value by a diagnostic means of a diagnostic operation value deciding section (10), and a decision is made whether the operating state is normal or not based on the comparison results. The quantities of state stored in the memory means for a predetermined past period may be employed for the diagnosis. If a decision is made that the operating state is abnormal, a remedy for that state is selected and displayed by an output means. The reliability of diagnosis can be enhanced furthermore by making a diagnosis again upon elapsing a predetermined time after the initial diagnosis and displaying a remedy based on the results of rediagnosis from the output means.
    • 一种用于自诊断冰箱的运行状态并指示如果存在异常的必要性的自诊断装置。 首先,测量多个量的状态并将其存储在存储器部分(7)中预定的时间段。 然后通过诊断操作值决定部(10)的诊断装置将基于状态量操作的状态量或诊断操作值与规定的阈值进行比较,并且判断操作状态是否正常 或者不是基于比较结果。 存储在存储器中的状态的量可以用于诊断。 如果判断为运行状态异常,则通过输出装置选择并显示该状态的补救措施。 通过在初始诊断之后经过预定时间再次进行诊断并基于来自输出装置的重新判断结果显示补救措施,可以进一步提高诊断的可靠性。
