Therefore, when the cut flowers can be used in the respective water tanks 21 to 23, the flower buds 24 in a state where the cut flowers are set in a bundle are inserted from the insertion openings of the upper lids 21a to 23a of the respective water tanks 21 to 23.

  In the flower showcase, the water supply mechanism 30 supplies live water to the water tanks 21 to 23. The water supply mechanism 30 is connected to a water supply source to supply water into the upper water tank 21, overflow pipes 32 to 34 piped to the water tanks 21 to 23, and pipes to the water tanks 21 to 23. The water supply pipe 31 is connected to an electrolyzed water generating device 40 that is a water supply source. In the flower showcase, since electrolyzed acidic water is used as live water for cut flowers, the electrolyzed water generating device 40 is installed in the lower part of the upper stage of the base 11.

  The electrolyzed water generating device 40 is a diaphragm electrolysis type electrolyzed water generating device. The electrolyzed water generating apparatus 40 performs, for example, diaphragm membrane electrolysis using a dilute aqueous solution of an inorganic salt such as potassium chloride or sodium chloride as the electrolyzed water. In the anode side electrolysis chamber of the diaphragm electrolyzer, strong acid electrolysis is performed. The generated acidic water is generated and, in a synchronous manner, strongly alkaline electrolytically generated alkaline water is generated in the cathode side electrolysis chamber of the diaphragm cell. In the flower showcase, the strongly acidic electrolytically generated acidic water generated by the electrolytic water generating device 40 is mixed with tap water to obtain a moderately diluted electrolytically generated acidic water, which is used as cut water. To use.

  The water supply pipe 31 constituting the water supply mechanism 30 is connected to the outflow pipe connected to the anode side electrolysis chamber of the electrolyzed water generating device 40, and during electrolysis operation of the electrolyzed water generating device 40, the anode side electrolysis chamber The electrolytically generated acidic water generated in step 1 is supplied to the upper water tank 21. A cooling device 38 a for cooling the electrolytically generated acidic water flowing through the water supply pipe 31 is interposed in the middle of the water supply pipe 31. 3, reference numeral 23b is a float switch, reference numerals 35a, 36a and 37a are drain valves, reference numeral 41 is a supply pipe for electrolyzed water, reference numeral 42 is an electromagnetic valve, and reference numeral 43 is a pressure reducing valve.

  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.

  Further, in the flower showcase, the electrolytically generated acidic water in such a pH range is cooled and used as live water. Cooling temperature is 5-25 degreeC, Preferably it is 10-20 degreeC, Comprising: By maintaining the electrolysis production | generation acidic water (live water) accommodated in each water tank 21-23 in each water tank 21-23, Suppresses the volatilization of chlorine gas from live water and the flowering and maturation of cut flowers. In addition, in the said flower showcase, in order to cool electrolysis production | generation acidic water, although the cooling device 38a is interposed in the middle of the water supply pipe 31, the fresh water accommodated in each water tank 21-23 is used. In order to cool, a cooling pipe 38b may be provided on the inner wall of each of the water tanks 21 to 23 as shown in FIG.

  In the flower showcase, an ultraviolet irradiation device 39 is disposed at a position above the upper water tank 21 in the case body 10. The ultraviolet irradiation device 39 irradiates each of the water tanks 21 to 23 and the electrolytically generated acidic water that is the live water when replacing the fresh water in each of the water tanks 21 to 23, and is often used when replacing the live water. By irradiating the volatilizing chlorine gas with ultraviolet rays, excess chlorine gas can be decomposed, and at the same time, ethylene gas generated from cut flowers can be decomposed. However, the ultraviolet irradiation is kept as short as possible so as to suppress the decrease in the life of cut flowers and the deterioration of the resin parts constituting the flower showcase as a result of the ultraviolet irradiation.

The supply of live water 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).
When the electrolysis operation of the electrolyzed water generating device 40 is started, strongly acidic electrolyzed acidic water is generated in the anode-side electrolysis chamber of the diaphragm electrolyzer, and the generated electrolyzed acidic water is used as live water as a water supply pipe 31. The live water that has been continuously supplied to the upper water tank 21 through the upper water tank 21 and has overflowed from the upper water tank 21 is supplied to the middle water tank 22 through the overflow pipe 32, and the live water that has overflowed from the middle water tank 22 has overflowed. The live water that has been supplied to the lower water tank 23 through 33 and overflowed from the lower water tank 23 is drained through the overflow pipe 34.

  During this time, the electrolytically generated acidic water supplied into the respective water tanks 21 to 23 as living water is cooled to a predetermined temperature set by the cooling device 38a interposed in the middle of the water supply pipe 31, and each of the water tanks 21 to 21 is cooled. 23 is supplied as cooled live water. During this time, when the water level in the lower water tank 23 reaches a predetermined water level, the float switch 23b installed in the lower water tank 23 detects this, and this detection signal is sent to the control device. Output. Thereby, a control apparatus stops the electrolysis driving | operation of the electrolyzed water production | generation apparatus 40, and complete | finishes supply of the live water in each water tank 21-23.

  As a result, the cut flowers set in the water tanks 21 to 23 in a state of being set in a bundle on the flower basket 24 are in a state where they are used in the cooled fresh water, and the cut flowers are displayed in this state. Become. In this case, the electrolytically generated acidic water supplied into each of the water tanks 21 to 23 instantly volatilizes chlorine gas in the vicinity of the stems of cut flowers utilized in the respective water tanks 21 to 23, and the volatilized chlorine gas is cut flowers. Reacts with the generated ethylene to remove it.

  In the flower showcase, when the cut flowers are displayed for a long time, the live water contained in each of the water tanks 21 to 23 is gradually reduced by sucking up and evaporating by the cut flowers, and the sterilizing ability of the live water is reduced. Decreases gradually due to volatilization of the effective chlorine component. For this reason, in the flower showcase, when the water level of the live water in each of the water tanks 21 to 23 falls to a predetermined water level that has been set, or when a predetermined time that has been set as the exhibition time has passed, Replacing fresh water in the water tanks 21 to 23 is performed. In the flower showcase, two methods are adopted as a method for replacing the live water in each of the water tanks 21 to 23.

  The first method of exchanging fresh water is performed when the float switch 23b detects that the cut flowers are displayed for a long time and the water level in each of the water tanks 21 to 23 falls to a predetermined water level. Is the method. In this method, the float switch 23b detects this when the water level in the aquarium 23 drops to a predetermined water level that has been set, and outputs this to the control device as a detection signal. Based on the detection signal, the electrolysis operation of the electrolyzed water generating device 40 is resumed, and the electrolysis operation is continued for a set predetermined time. Thereby, the fresh water in each water tank 21-23 is completely replaced.

  The second method for replacing fresh water is when the display time of cut flowers has elapsed for a predetermined time without waiting for the time when the level of live water in each of the water tanks 21 to 23 drops to the predetermined water level. Is a method in which the control device restarts the electrolysis operation of the electrolyzed water generating device 40 at the time. At this time, the control device restarts the electrolysis operation of the electrolyzed water generating device 40 and continues the electrolysis operation for a set time. Thereby, the fresh water in each water tank 21-23 is completely replaced.

  In these methods of exchanging fresh water, when the electrolytically generated acidic water is supplied into each of the water tanks 21 to 23, or when the supply is finished, the ultraviolet irradiation device 39 makes a short time on each of the water tanks 21 to 23. During this period, ultraviolet irradiation is performed. Thereby, it is possible to decompose the excess chlorine gas by irradiating the chlorine gas that volatilizes a lot during the replacement of the living water with ultraviolet rays, and simultaneously decompose the ethylene gas generated from the cut flowers.

  As described above, the flower showcase employs means for simultaneously supplying the water tanks 21 to 23 with the water supply mechanism 30 by employing electrolytically generated acidic water as live water. For this reason, the living water accommodated in each of the water tanks 21 to 23 has high sterilizing ability and has no unevenness in characteristics, and during the period in which the sterilizing ability continues, generation of scale or mold in each of the water tanks 21 to 23 occurs. It can be significantly suppressed.

  For this reason, in this flower showcase, as in the case of this type of conventional flower showcase, troublesome removal work such as dirt and mold that inevitably occur in each of the water tanks 21 to 23 and inside and outside the flower tub 24 is performed. While being able to eliminate, the frequency of replacement | exchange of the live water accommodated in each water tank 21-23 can be reduced. When replacing the live water in each of the water tanks 21 to 23 with new live water, the electrolyzed water is supplied from the electrolyzed water generating device with a constant concentration and uniform characteristics. There is no stress caused by the density unevenness.

  In the flower showcase, when supplying fresh water into each of the water tanks 21 to 23, it volatilizes from the electrolytically generated acidic water discharged from the tip opening of the water supply pipe 31 and the tip opening of each overflow pipe 32 to 34. Chlorine gas and ethylene generated from cut flowers can be reacted to remove ethylene, thereby delaying the maturation of cut flowers and maintaining the freshness of cut flowers.

  In the flower showcase for displaying cut flowers according to the present invention, a display experiment is performed in which cut flowers are displayed for a long period (16 days). An experiment was conducted in which the replacement method was adopted and the replacement was performed once every three days.

  In this experiment, as the electrolytically generated acidic water that is live water, the pH is in the range of 3.5 to 4.5, the effective chlorine concentration is in the range of 5 ppm to 10 ppm, and the water temperature is in the range of 10 ° C to 20 ° C. Using electrolytically generated acidic water, exhibiting cut flowers using each electrolytically generated acidic water as live water, and exchanging all the live water in each tank 21-23 once every 3 days during the exhibition period, Exhibited for 16 days.

  In the cut flower display experiment, the retention of cut flowers was good during the display period. In addition, when the fresh water in each of the water tanks 21 to 23 was replaced, the water tanks 21 to 23 and the flower bud 24 were visually observed. There was no need to do.
