Abstract: By supplying DC to electrodes (142a and 142b), chlorine-ion containing water is electrolyzed and acid water and alkali water are generated. Mineral eluted substances (141) react with the acid water to elute mineral components. Moreover, by electrolyzing the chlorine-ion containing water, the hypochlorous concentration of the chlorine-ion containing water increases. Mineral water is led into a cold water storage tank (4). Thereby, mineral water is supplied from the cold water storage tank (4) and moreover, breeding of bacteria is restrained in the cold water storage tank (4).

Abstract: An apparatus for supplying drinking water has a construction such that a first branch pipe (P2) and a second branch pipe (P3) are connected to a water supply pipe (P1) in which tap water flows, a cold water generating tank (3) is provided in the first branch pipe (P2), and the second branch pipe (P3) is provided with an ion exchange device (4) and a hot water generating tank (5). When the tap water is allowed to flow in the first branch pipe (P2), cold water is generated in the cold water generating tank (3). Also, when the tap water is allowed to flow in the second branch pipe (P3), the tap water is softened by the ion exchange device (4), and is further heated in the hot water generating tank (5). Therefore, not only cold water can be supplied but also hot water from which mineral components are removed can be supplied.

Abstract: An apparatus for supplying drinking water comprising a container (1) in which drinking water such as natural water or tap water is accommodated and which is arranged detachably; a water cooler (22) which cools drinking water supplied from the container (1); a sterilizer (5) which is installed in the water cooler (22) and sterilizes drinking water in the water cooler (22); a cold water valve (23) which controls supplying operation and stopping operation for drinking water in the water cooler (22); and a container detector (4) which detects whether or not the container (1) has been detached, wherein, after the container detector (4) has detected a state in which the container (1) has been detached, drives the sterilizer (5) for a predetermined period. This enables bacteria having invaded into the container (1) to be killed in a well-timed way.

Abstract: A mineral-water producing apparatus that including: an electrolytic tank to which raw water, such as city water, is supplied; a mineral eluting material(s) arranged in the electrolytic tank; and a pair of electrodes, a cathode and an anode, arranged in the electrolytic tank, where mineral water is produced by applying a DC voltage across the electrodes, and the resulting mineral water is delivered to its terminal through a water-delivery pipe, wherein the apparatus further includes chlorine-concentration control means which including: a main water-delivery pipe and a bypass water-delivery pipe into which a portion of the water-delivery pipe is diverged; and a water purification tank provided in the main water-delivery pipe for removing an available chlorine component.

Abstract: A mineral-water producing apparatus that includes: an electrolytic bath to which raw water, such as city water, is supplied; a mineral eluting material(s) arranged in the electrolytic bath; and electrodes for applying DC voltage with which the water in the electrolytic bath is electrolyzed so that a mineral element(s) is eluted from the mineral eluting material (s), where the mineral water produced in the electrolytic bath is delivered to the outside thereof, characterized in that the apparatus further includes: a pH sensor which detects the pH of the raw water; and a controller which controls the conducting time duration for the electrodes based on the detection signal from the pH sensor. Thus, mineral water having a desired mineral concentration is produced.

Abstract: A apparatus for supplying drinking-water has a drinking-water storage unit, a drinking-water supply system capable of introducing the drinking-water into a drinking cup from the drinking-water storage unit, and an antimicrobial member provided in the drinking-water supply system. This allows easy bacteriostasis or sterilization of the drinking-water poured from the nozzle. Further, an activity effect of the antimicrobial member inhibits the growth of bacteria in the drinking-water supply system.

Abstract: The mineral water making apparatus has a structure that includes a water tank having a mineral eluting material disposed therein, a water supply pipe for introducing raw water such as tap water into the water tank, and a water intake pipe for intaking mineral water made in the water tank; and an acidic food-additive supply apparatus for supplying an acidic food additive into the water tank is further installed. Since the acid concentration in the water tank thereby rises, the mineral-eluting efficiency of the mineral eluting material is improved, and the mineral concentration is elevated.
