Abstract: Refrigerator (100) includes RFID tag (21) in which an appliance information is stored, product label (23) that indicates the appliance information, and a plurality of parts that configure refrigerator (100). In addition, product label (23) and RFID tag (21) are disposed on the same part among the plurality of parts. In this way, refrigerator (100) is provided, in which product label (23) and RFID tag (21) for identifying the individual home appliance are centrally managed and a mismatch between the appliance information items is prevented in advance.

Abstract: A refrigerator includes refrigerator body having a plurality of storage rooms, a plurality of doors that open and close the plurality of storage rooms, and RFID tag that performs proximity communication. In addition, RFID tag is provided on the uppermost door among a plurality of doors. In this way, a specific communication failure of refrigerator or dirt on mobile terminal which easily occurs due to the spilling of water or dirt at the time of taking food in and out of the refrigerator can be prevented, and thus, it is possible to provide refrigerator having a high reliability.

Abstract: A bottom-freezer refrigerator comprises a generally rectangular box-like refrigerator housing including a top division and a bottom division with an adiabatic partition wall intervening between the top and bottom divisions. The top division has a refrigerator chamber and a crisper chamber both defined therein. The bottom division has a freezer compartment defined therein. The bottom-freezer refrigerator of the structure described above also comprises a first cooler provided in the top division at a location spaced from a rear wall portion of the crisper chamber, a first circulating fan disposed in the vicinity of the first cooler, a second cooler provided in the bottom division, and a second circulating fan disposed in the vicinity of the second cooler. The refrigerator chamber and the crisper chamber are cooled by the first cooler in cooperation with the first circulating fan, whereas the freezer compartment is cooled by the second cooler in cooperation with the second circulating fan.

Abstract: A refrigerator has a refrigerator compartment, a freezer compartment, and a low-temperature storage chamber formed in the refrigerator compartment and having a temperature lower than that of the refrigerator compartment. The refrigerator includes a compressor, a condenser, a first throttling device, a channel control valve, a refrigerator cooling unit, and a freezer cooling unit connected in series to form a refrigerating cycle. The refrigerator cooling unit and the freezer cooling unit are accommodated in the refrigerator compartment and the freezer compartment, respectively.
