PROBLEM TO BE SOLVED: To remove harmful substance from air in a storage chamber with a simple configuration by eliminating the need for any insulating structure with a high voltage.SOLUTION: A refrigerator in an embodiment includes a filter. This filter is installed in a cold air passage and configured with a plurality of holes through which air flowing in the cold air passage can pass. A photocatalyst with visible light responsiveness is adhered to the internal surface of each of the plurality of holes, and the filter is irradiated with visible rays of light from a light source in a closed state of a door so that the photocatalyst of the filter can be excited.COPYRIGHT: (C)2012,JPO&INPIT【課題】高電圧の絶縁構造が不要な簡単な構成で貯蔵室内の空気から有害物質を除去すること。【解決手段】実施例の冷蔵庫はフィルタを備えている。このフィルタは冷気通路内に設けられたものであり、冷気通路内を流れる空気が通過可能な複数の孔を有している。これら複数の孔のそれぞれの内面には可視光応答性の光触媒が付着されており、扉の閉鎖状態では光源からフィルタに可視光が照射されることでフィルタの光触媒が励起する。【選択図】図1
