PROBLEM TO BE SOLVED: To provide a refrigerator in which frost formation hardly occurs in a refrigeration chamber discharge duct, regarding frost formation by a cold air backflow in the refrigeration chamber discharge duct while a blower is stopped.SOLUTION: A refrigerator which includes a freezing chamber 6 at an upper part and a refrigeration chamber 7 at a lower part includes: a cooler 8 arranged on a back surface of the freezing chamber 6; a coil cover 9 located in front of the cooler 8, for constituting an air passage for cold air blown by a blower, and made of a heat insulation material; cold air adjustment means provided at the coil cover 9, and for adjusting the cold air in the refrigeration chamber 7 manually; and a refrigeration chamber discharge duct 16 arranged being connected below the cold air adjustment means. As the refrigeration chamber discharge duct 16 includes a cold air backflow prevention material, collision between warm air in the refrigeration chamber and the cold air from a cooling chamber can be prevented by the cold air backflow prevention material while the blower 14 is stopped, and frost formation in the duct can be prevented.SELECTED DRAWING: Figure 1 【課題】送風機停止時の冷蔵室吐出ダクト内冷気逆流による着霜に関し、冷蔵室吐出ダクト内に着霜しにくくする冷蔵庫を提供することを目的とする。【解決手段】上部に冷凍室６、下部に冷蔵室７を備えた冷蔵庫において、冷凍室７の背面に配置された冷却器８と、冷却器８の前面に位置して送風機による冷気の風路を構成する断熱材からなるコイルカバー９と、コイルカバー９に備え冷蔵室７の冷気を手動で調節する冷気調節手段と、前記冷気調節手段の下方に繋がって配置した冷蔵室吐出ダクト１６とを備え、冷蔵室吐出ダクト１６に冷気逆流防止材を備えたことにより、送風機１４停止時に冷蔵室内の暖気と冷却室からの冷気の衝突を冷気逆流防止材により防ぐことができ、ダクト内の着霜を防ぐことができる。【選択図】図１
