Description

  The present invention relates to a method for supplying fresh water into a water tank in a flower showcase for displaying cut flowers for displaying cut flowers in a water tank.

  As a form of a flower showcase for displaying cut flowers, there are a water tank that is arranged in multiple stages in the case body and contains fresh water for cut flowers, and is connected to a water supply source in the uppermost water tank. And a live water supply mechanism comprising an overflow pipe disposed in each of the water tanks and overflowing the live water supplied to the water tanks to supply water to the next water tank. There is a flower showcase for displaying cut flowers (see Patent Document 1).

  In a flower showcase for displaying cut flowers of this type (hereinafter sometimes simply referred to as the flower showcase), it is possible to maintain the freshness of each cut flower used in the fresh water contained in each tank. As long as it is required to withstand long-term exhibitions.

  By the way, in the flower showcase, as the live water, it is common to use normal tap water or water obtained by adding a life-extending agent (trade name: crizar, etc.) to the tap water. Since the live water has no sterilizing action or is extremely low, scale, mold, etc. are generated early in the water tank containing the live water. For this reason, the live water contained in each water tank is periodically replaced (for example, once every two days), and each water tank is washed before supplying new live water in each water tank. It is very easy to remove the scale and mold adhering to the inside of the aquarium, and the scale and mold adhering to the inside and outside of many florets used when cultivating cut flowers with a brush. Actually, it is a troublesome work.

  On the other hand, as means for maintaining the freshness of cut flowers, it has been proposed to employ electrolytically generated acidic water generated by an electrolyzed water generating device of a diaphragm electrolysis type as live water (see Patent Document 2). Since the electrolyzed acidic water has a high bactericidal action, it functions to maintain the freshness of cut flowers for a long period of time by greatly suppressing the occurrence of scale and mold in each tank. As a preferable electrolytically generated acidic water, strongly acidic electrolytically generated acidic water having a pH of 3 or less is recommended.

  In the flower showcase, electrolytically generated acidic water having a pH of 3.0 to 5.0, preferably electrolytically generated acidic water having a pH of 3.5 to 4.5 is employed as the living water. By adopting the electrolytically generated acidic water in such a pH range, the bactericidal ability latent in the electrolytically generated acidic water can be effectively and effectively utilized. In addition, in the said electrogenerated acidic water, it is preferable that the effective chlorine concentration which exhibits bactericidal ability exists in the range of 5 ppm-10 ppm.

  In the flower showcase, when cut flowers can be used in each of the water tanks 21 to 23, a flower bud 24 shown in FIGS. 3 and 4 is used. As shown in FIG. 4, the flower bud 24 is a cylindrical body with a bottom and has a conical shape that gradually expands from the bottom, and a plurality of slit-shaped inflow / outflow ports 24a are formed on the side wall near the bottom. It has. Although the inflow / outflow port 24a may be circular, it is important that the inflow / outflow port 24a is always submerged in fresh water when it is smaller than the hole diameter of the overflow pipes 32-34 and is set in each of the water tanks 21-23. It is.

  When the cut flower can be used in each of the water tanks 21 to 23, if the flower bud 24 is used, when the water is supplied into each of the water tanks 21 to 23 and the overflow water overflows from the overflow pipes 32 to 34, The petals and leaves that fall from the cut flowers and float on the fresh water in the flower bud 24 can be prevented from flowing out of the flower bud 24, and clogging of various pipes can be prevented.

  Water supply to each of the water tanks 21 to 23 in the flower showcase is performed by starting an electrolysis operation of the electrolyzed water generating device 40 that is a water supply source. Operation control of the electrolysis operation of the electrolyzed water device 40 is performed by a control device (not shown).
