PROBLEM TO BE SOLVED: To provide a refrigerator capable of securing a large catalyst area of a photocatalyst contacting cold, and providing a photocatalyst device in a stockroom that has a large volume and that can store therein many food items or bulky vegetables or the like.SOLUTION: In a refrigerator, a catalyst base carrying thereon a photocatalyst is attached so that the photocatalyst is exposed to a stockroom side of a back panel constituting a cold air path, and a light-emitting diode is provided on an inner surface of an inner box constituting the cold air path so as to emit light toward the catalyst base. The catalyst base is provided on a part of the back panel and the light-emitting diode provided in the inner box excites photocatalysis, so that a magnitude of the catalyst base can be arbitrarily set to make it possible to secure a sufficient catalyst area. Owing to this, it is possible to effectively remove odorous components from a stockroom having a high volume and sterilize the stockroom. Furthermore, carbon dioxide generated by a catalytic action of the photocatalyst can reduce an oxygen concentration of the stockroom, which can advantageously suppress respiration of vegetables and stock the vegetables in fresh states for a long time. |
