PROBLEM TO BE SOLVED: To reduce electric charge, to increase the content volume of a heat insulation box for food cooling, and to facilitate maintenance of a secondary battery to be a heavy object.SOLUTION: A refrigerator includes a refrigerator body, a storage chamber subjected to heat insulation section, time correction means, and a calculation control part performing arithmetic processing for signals output from the time correction means. The refrigerator automatically corrects refrigerator time information in which, conventionally, an error occurs with the lapse of time, by automatically performing time correction, and thereby important time recognition can be accurately performed in standardization of electric power, utilization of night electric power and the like, and time correction that is normally performed by hand can be saved by performing it automatically. |
