first embodiment
[0042] FIGS. 1 to 3 show first embodiment of an apparatus for supplying mineral water of the present invention. First, a schematic configuration of the apparatus for supplying mineral water is described by referring to FIG. 1.
[0043] The apparatus for supplying mineral water has a mineral water generation unit 1 for generating mineral water, purifying bath 2, pump 3, cold water storage tank 4, hot water storage tank 5, cold water supply valve 6a, hot water supply valve 6b, and water supply valve 6c.
[0044] The water supply valve 6c is set to a water supply pipe 7a for supplying tap water (chlorine-ion containing water) to the water generation unit 1. The mineral water discharged from the mineral water generation unit 1 is supplied to the purifying bath 2 through a first leading pipe 8a. The pump 3 is set to a second leading pipe 8b. The front end of the second leading pipe 8b is branched into two pipes. The front end of one branch pipe 8b1 is connected to the cold water storage tank ...
second embodiment
[0061] According to this embodiment, when opening the return valve 6d and driving the pump 3, mineral water circulates as shown by the continuous line arrow in FIG. 5. That is, the mineral water in the cold water storage tank 4 flows from the cold water supply pipe 8d to return pipe 8e, return valve 6d, and mineral water generation unit 1 in order. Moreover, the mineral water in the mineral water generation unit 1 flows into the cold water storage tank 4 similarly to the case of the
[0062] Thus, it is possible to replace the mineral water in the cold water storage tank 4 with the mineral water newly generated by the mineral water generation unit 1. As a result, it is possible to keep the hypochlorous concentration at a predetermined value. Moreover, it is possible to sterilize a mineral-water supply pipe system.
[0063] Furthermore, when applying a DC current to the electrodes 142a and 142b at the same time as circulation of the above mineral water, the sterilizing effect of the miner...
fifth embodiment
[0070] According to this embodiment, the bypass valve 6h is opened and the water leading valve 6g is closed to drive the pump 3. Thereby, as shown by continuous line arrows in FIG. 8, the mineral water in the cold water storage tank 4 circulates. That is, the mineral water in the cold water storage tank 4 flows from the cold water supply pipe 8c to the return pipe 8e, return valve 6d, and mineral water generation unit 1 in order. Moreover, the mineral water in the mineral water generation unit 1 flows from the first leading pipe 8a to the bypass pipe 8g, the second leading pipe 8b, and cold water storage tank 4 in order. Thereby, it is possible to sterilize a piping system excluding the purifying baths 2 and 2a. Moreover, it is possible to set the hypochlorous concentration of the mineral water in the cold water storage tank 4 to a desired value. Description of other configurations and functions is omitted because the configurations and functions are the same as those of the
