- the control means 3 suppresses cooling by increasing the set temperature of each storage room on weekdays as compared with weekends. Thereby, it can save electricity, maintaining the preservation
- control means 3 gradually changes the set temperature of each storage room to be higher on weekdays as the weekend approaches. Thereby, it is possible to further save electricity while maintaining the preservation quality of food and drink.
- the control means 3 sets the set temperature of each storage room on the day on which shopping is scheduled compared to other days. Cooling is promoted by lowering.
- the cooling control since the door opening / closing frequency and the amount of food and drink stored in the refrigerator 1000 can be estimated based on the shopping pattern of the user household, by changing the cooling control based on the shopping pattern of the user household, overcooling and cooling Insufficiency is prevented, efficient cooling becomes possible, and a cooling operation without waste can be performed, so that a high power saving effect is obtained.
