Abstract (en)
[origin: EP2682694A1] A refrigerator includes a storage room that is divided into sections by a heat insulation wall and a heat insulation door, and stores storage items, a light source that is disposed inside the storage room, a light sensor (21) that detects the illumination light illuminated from the light source, and a calculation control unit (1) that performs a calculation process based on a detection result of the light sensor (21). The calculation control unit(1) includes an attenuation rate calculation unit (81) that calculates an attenuation rate from a reference storage room illuminance in a state that the storage items are stored, based on the reference storage room illuminance in a state that the storage items are not stored in the storage room and a detected illuminance by the light sensor (21), and a storage state estimation unit (82) that estimates a storage amount of the storage items, based on a calculation result of the attenuation rate calculation unit (81).
