Abstract: PROBLEM TO BE SOLVED: To save energy by reducing an inward penetration heat, in the constitution of the heat insulation box body and the heat insulation door of a refrigerator. SOLUTION: Outer and inner boxes 40 and 43 of a heat insulation box body are formed of resin. An inclination part 58 provided near the peripheral edge part of a door inner plate 48 is positioned facing an inclination part 57 situated near the opening part of the inner box 43 to form a throat 59. A seal member 60 to seal the throat 59 is provided. This constitution reduces a quantity of heat transferred and penetrating from the outer box 40 to a flange 42. Further, an amount of heat flowing through the throat 59 is also reduced.

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.

Abstract: PROBLEM TO BE SOLVED: To save energy by making a decision whether the condenser temperature is higher than a specified level or not, determining the installation environment of refrigerator if it is higher than the specified level, indicating the results to notify the installation environment to a user thereby keeping the condenser temperature at a low level. SOLUTION: When the installation environment of a refrigerator deteriorates, a condenser temperature setting means 1 sets a condenser temperature higher than the condenser control temperature when the refrigerator is covered with a wall on the back and side thereof. A condenser temperature determining means 2 compares a condenser temperature detected by a condenser temperature detecting means with a temperature set by the condenser temperature setting means 1 and delivers an output if the former is higher. A decision means 3 lights an indicating means 4 to notify that the installation environment of the refrigerator is bad if the condenser temperature determining means 2 delivers an output otherwise unlights the indicating means 4 to notify that the installation environment of the refrigerator is good.
