Abstract

PROBLEM TO BE SOLVED: To give a precise lead to the user of a refrigerator, by comparing the door open reference time of a freezing room with the door open time of a freezing room, and the door open reference time of a cold storage room with the door open time of the cold storage room so as to judge whether they are over the door open reference times or not, and judge the abnormality and abnormality of the temperatures of the freezing room and the cold storage room. SOLUTION: In either case or both cases of the door open time 9 of a freezing room being over the door open reference of the freezing room and the door open time 10 of a cold storage room being over the door open reference time 12 of the cold storage room, an output part 16 outputs the results, judging that the doors of the cold storage room and the freezing room are too opened. Conversely, in case that the door open time 9 of the freezing room is under the door open reference time 11 of the freezing room and/or the door open time 10 of the cold storage room is under the door open standard time of the cold storage room, the output part 16 outputs the results, judging that it is caused by other factor than the excessive opening o the door of the freezing room. Hereby, this controller gets the concrete contents such as that the number of times of opening the door of the refrigerator is large, etc., and give precise lead and advise to the user of the refrigerator.
