PROBLEM TO BE SOLVED: To provide a device for rationally replacing flower water (electrolytically-generated acid water) in each water tank in a flower showcase that employs the electrolytically-generated acid water as the flower water for cut flowers, especially for properly replacing the flower water in each tank without consuming the electrolytically-generated acid water wastefully.SOLUTION: In the flower showcase for displaying cut flowers, a plurality of water tanks 20 for holding flower water for cut flowers are arranged in a plurality of steps like a stair. An electrolyzed water generator 40 serving as a source of flower water is operated for electrolysis, and the electrolytically-generated acid water generated is supplied into the water tanks 20 on the upper step as flower water. As the flower water supplied into each of the water tanks 20 on the upper step is held at a certain level, the water tanks 20 on the next and lower step are caused to overflow, to supply the flower water into the water tanks 20 on the lower stage. |
