To provide a refrigerator capable of further improving food preservation by not only reducing oxygen that is one of deterioration factors of stored food, but also increasing carbon dioxide.SOLUTION: A refrigerator comprises: a heat insulation box forming a cold storage chamber and a refrigeration chamber; a refrigeration cycle configured to generate cold air; and a cold air supply passage configured to supply the cold air from the refrigeration cycle to the cold storage chamber and the refrigeration chamber by a blower fan. The refrigerator includes a sealed container provided in a storage chamber, and a combustor configured to reduce oxygen concentration and increase carbon dioxide in the sealed container.SELECTED DRAWING: Figure 7 【課題】貯蔵中食品の劣化要因の一つである酸素を減らすだけでなく、二酸化炭素を増やすことで、食品の保存性をより一層向上させた冷蔵庫を提供する。【解決手段】冷蔵室及び冷凍室を形成する断熱箱体と、冷気を生成する冷凍サイクルと、前記冷凍サイクルからの冷気を送風ファンによって前記冷蔵室及び前記冷凍室に供給する冷気供給路と、を備えた冷蔵庫において、前記貯蔵室内に設けられた密閉容器と、前記密閉容器内の酸素濃度を減少させて二酸化炭素濃度を増加させる燃焼装置と、を有する構造とした。【選択図】図７
