PROBLEM TO BE SOLVED: To provide a refrigerator including a visible light-responding photocatalyst and a light source for the catalyst, each disposed in a cold air passage in communication with a storage chamber, in which the light from the light source can be extracted to the storage chamber side and dew condensation in a light-extracting part at the storage chamber side is prevented as much as possible.SOLUTION: A refrigerator includes: a cold air passage where a cold air cooled by a cooler flows a duct member formed of a heat insulating member, which is disposed in the cold air passage and has a cold air passage part where the cold air flowing in the cold air passage flows a pass-through opening formed in the duct member, with one end of the opening facing the cold air passage part and the other end facing the storage chamber a visible light-responding photocatalyst disposed in the cold air passage part to bring the cold air passing therethrough into contact with the photocatalyst a light source disposed close to the photocatalyst and irradiating the photocatalyst with visible light including light at a wavelength to excite the photocatalyst and a light guide member disposed in the pass-through opening, for guiding the light emitting from the light source to the storage chamber side.COPYRIGHT: (C)2013,JPO&INPIT【課題】貯蔵室と連通する冷気通路内に可視光応答型光触媒およびこれ用の光源を設けたものにおいて、光源の光を貯蔵室側に取り出すことができ、しかも貯蔵室側の光取出し部分に結露が発生することを極力防止する。【解決手段】本実施形態の冷蔵庫は、冷却器により冷却された冷気が流れる冷気通路と、断熱部材により形成されて冷気通路内に設けられその冷気通路を流れる冷気が流れる冷気通路部を有するダクト部材と、ダクト部材に一端部が冷気通路部に臨むとともに他端部が貯蔵室に臨むように設けられた貫通口部と、冷気通路部にここを通る冷気が接触するように設けられた可視光応答型光触媒と、この光触媒の近傍に設けられ当該光触媒に対してこれを励起する波長の光を含む可視光を照射する光源と、貫通口部に設けられ光源から発せられる光を貯蔵室側に導く光ガイド部材と、を備える。【選択図】図2
