Description

光触媒装置Photocatalyst device
　本発明は、光触媒を利用して空気の脱臭や除菌などを行うための光触媒装置の技術に関する。 The present invention relates to a technique of a photocatalyst device for deodorizing and sterilizing air using a photocatalyst.
　従前より、空気の脱臭や除菌を行うための光触媒装置が知られている。たとえば、特開２０１４－２１９１３０号公報（特許文献１）には、光触媒を利用した冷蔵庫が開示されている。特開２０１４－２１９１３０号公報（特許文献１）によると、冷気通路を構成する背面パネルの貯蔵室側に光触媒が露出するように光触媒を担持した触媒基台を取り付け、触媒基台に向けて光を照射するように冷気通路を構成する内箱内面に発光ダイオードを設けた。背面パネルの一部に触媒基台を設け、内箱に設けた発光ダイオードによって光触媒を励起するようにしたので、触媒基台の大きさが任意に設定でき十分な触媒面積を確保することができる。このため、容積の大きい貯蔵室の臭気成分を効果的に脱臭したり、除菌することが可能となる。更には、光触媒の触媒作用によって発生する二酸化炭素によって貯蔵室の酸素濃度を低減することができるので、野菜類の呼吸作用を抑制して野菜類を新鮮な状態で長く保管することができるという効果も奏するようになる。 Photocatalytic devices for deodorizing and sterilizing air have been known for some time. For example, Japanese Patent Application Laid-Open No. 2014-219130 (Patent Document 1) discloses a refrigerator using a photocatalyst. According to Japanese Patent Application Laid-Open No. 2014-219130 (Patent Document 1), a catalyst base carrying a photocatalyst is attached to the storage chamber side of the back panel constituting the cold air passage so that the photocatalyst is exposed, and light is directed toward the catalyst base. A light emitting diode was provided on the inner surface of the inner box constituting the cold air passage so as to irradiate. Since the catalyst base is provided in a part of the back panel and the photocatalyst is excited by the light emitting diode provided in the inner box, the size of the catalyst base can be arbitrarily set and a sufficient catalyst area can be secured. .. Therefore, it is possible to effectively deodorize or sterilize the odorous components of the storage chamber having a large volume. Furthermore, since the oxygen concentration in the storage chamber can be reduced by the carbon dioxide generated by the catalytic action of the photocatalyst, the effect of suppressing the respiratory action of the vegetables and keeping the vegetables in a fresh state for a long time is possible. Will also play.
