PROBLEM TO BE SOLVED: To reduce replacement frequency of water for flower arrangement in each water tank 21-23 by greatly suppressing generation of water stain, mold or the like on the inside of each water tank 21-23 or on the inside or the outside of each flower bucket 24 in a flower showcase for cut flower exhibition, and to remove a troublesome removal work for "removing water stain, mold or the like adhering onto the inside of each water tank or onto the inside or the outside of each flower bucket" when replacing water for flower arrangement.SOLUTION: A diaphragm electrolysis type electrolyzed water generation device 40 which is a water supply source and water spray nozzles 51, 52 are disposed in a case body 10, and generated electrolytically-generated acid water is supplied into each water tank 21-23 through a water supply pipe 31 and each overflow pipe 32-34, and utilized as water for cut flowers arranged in each water tank 21-23. Further, when supplying electrolytically-generated acid water into each water tank 21-23, water is sprayed periodically from each water spray nozzle 51, 52, to thereby remove chlorine gas or ethylene existing in the atmosphere.COPYRIGHT: (C)2012,JPO&INPIT【課題】切り花展示用フラワーショーケースにおける各水槽21~23内や各花桶24の内外での水垢やカビ等の発生を大幅に抑制して、各水槽21~23内の活け水の入れ替え頻度を低減するとともに、活け水の入れ替時の「各水槽内および花桶内外に付着している水垢やカビ等除去する」面倒な除去作業を解消する。【解決手段】ケース本体10内に、給水源である有隔膜電解式の電解水生成装置40と、水噴霧ノズル51,52を配設して、生成される電解生成酸性水を給水管31、各オーバフロー管32~34を通して各水槽21~23内に供給して、各水槽21~23に活けられる切り花の活け水として利用する。また、各水噴霧ノズル51,52からは、電解生成酸性水を各水槽21~23内に供給する際、および、定期的に水を噴霧して、雰囲気に存在する塩素ガスやエチレンを除去する。【選択図】 図2
