Abstract: The present disclosure provides a usage notification device that adds, to a refrigerator not provided with a communication function, the function of notifying a communication terminal of usage. The usage notification device includes an attachment portion, a wireless communication unit, a door open/closed recognition unit, and a notification control unit. The attachment portion attaches the usage notification device to an exterior of the refrigerator. The wireless communication unit performs a wireless communication with the communication terminal. The door open/closed recognition unit recognizes the open or closed state of the refrigerator. The notification control unit transmits the usage information on the refrigerator based on the door open or closed state of the refrigerator, to the communication terminal via the wireless communication unit.

Abstract: In a storage compartment (124), storage spaces having different mist concentrations are formed such that effects of a mist is more efficiently utilized to provide a refrigerator with improved usability. The storage compartment (124) includes a first storage unit (164) that has a high mist concentration. The first storage unit (164) includes a spray device (167) and is disposed in a position outside an air path of cool air between a discharge port (152) through which the cool air flows in from outside the storage compartment (124) and a suction port (149) through which the cool air is discharged to outside the storage compartment (124). Thus, mist concentration inside the first storage unit (164) can be increased.

A refrigerator (100) for forcibly circulating cold air which is gas cooled in a cooling compartment (110), the refrigerator including: a first storage compartment (107) disposed on the way of an air passage; a spray device (131) which sprays mist into the first storage compartment (107); a damper (145) disposed upstream of the first storage compartment (107); a delay unit (156) which generates, based on an open signal issued when the damper (145) is opened, a first signal for stopping the operation of the spray device (131) after an elapse of a first time period, and to generate, based on a close signal issued when the damper (145) is closed, a second signal for starting the operation of the spray device (131) after an elapse of a second time period; and a control unit (146) which controls the spray device (131).

Abstract: A refrigerator includes: a main body including an opening in a front face; a semiconductor light-emitting device disposed on an inner wall of the main body, emitting light toward an inside of the main body; and a cover. The cover includes: a light-transmission part disposed with a transmission axis A inclined toward a back of the main body more than an inner wall axis C is, the transmission axis A being perpendicular to an outer face of the light-transmission part that faces the inside of the main body, and the inner wall axis C being perpendicular to the inner wall face on which the semiconductor light-emitting device is disposed; and a support part supporting the light-transmission part. The semiconductor light-emitting device has a light axis B which extends in the same direction as or is inclined toward the opening more than the transmission axis A is.
