Title: Refrigerator and system
Inventor: NAKAGAWA MASASHI
IPC: F25D23/02
Filed: 2021-03-25
Abstract: To provide a refrigerator satisfactorily imaging food products in a storage chamber to facilitate discrimination of the food products from outside.SOLUTION: A refrigerator comprises a control part controlling an imaging device imaging a storage chamber. An illumination device fitted in the storage chamber and illuminating the inside of the storage chamber is used both at the time of normal use based on door open/close detection means and at the time of imaging by the imaging device. Illuminance in the inside of the storage chamber is constituted so as to be lower at the time of imaging than at the time of normal use, and the influence of reflected light from the inner surface of the refrigerator can be drastically reduced and clear images can be photographed while attaining common use of the illumination device. It is therefore possible to provide the refrigerator facilitating discrimination of food items in the refrigerator and having excellent user-friendliness.SELECTED DRAWING: Figure 18
