    摘要： Refrigerator (50) includes a storage chamber partitioned by a heat insulation wall and a heat insulation door, for storing a storage object, storage-volume estimating unit (23) for estimating a storage volume in the storage chamber, and memory unit (64) for memorizing a result of estimation by storage-volume estimating unit (23). Further, refrigerator (50) includes arithmetic control unit (22) for calculating a storage change volume based on a result of estimation of the storage volume up to a last time memorized in memory unit (64) and a result of estimation by the storage-volume estimating unit, and for controlling an output operation of an electrofunctional part. The arithmetic control unit compares a predetermined threshold value with the storage change volume, and decides that a storage volume changed when the storage change volume exceeds the threshold value, and controls an output operation of the electrofunctional part.

    摘要： 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).

    摘要： A refrigerator includes a storage room having an opening portion in a front surface, first light emission unit (20a) that is provided on a top surface of the storage room, first light detection unit (21a) that detects light illuminated from first light emission unit (20a), and concave portion (84) that is provided on a side surface of the storage room. First light detection unit (21a) is provided in concave portion (84). In this way, the refrigerator in which the storage state of the storage items in the refrigerator can be estimated is provided. By performing control in accordance with the storage state, the freshness preservation is improved and the overcooling can be prevented, and then the power consumption can be suppressed.
