Abstract

An apparatus for producing reducing water that maintains a neutral range of pH and exhibits superior reducing force. The apparatus for producing reducing water includes an electrolytic bath including a cathode chamber provided with a cathode, an anode chamber provided with an anode, and an intermediate chamber interposed between the cathode chamber and the anode chamber, wherein the cathode chamber and the intermediate chamber are provided with an inlet through which water is supplied, and an outlet through which water is discharged, a cation exchange membrane is provided between the cathode chamber and the intermediate chamber, and the intermediate chamber includes a cation exchange resin that dissociates hydrogen ions when the cation exchange resin reacts with water.

First claim

What is claimed is:

1. An apparatus for producing reducing water comprising:
an electrolytic bath comprising a cathode chamber provided with a cathode, an anode chamber provided with an anode, and an intermediate chamber interposed between the cathode chamber and the anode chamber, wherein the intermediate chamber comprises a cation exchange resin that dissociates hydrogen ions when the cation exchange resin reacts with water; and
a circulator to supply water to the intermediate chamber and supply water discharged through the cation exchange resin to the intermediate chamber again, the circulator comprising a water tank to store water supplied to the intermediate chamber, a channel to enable water present in the water tank to circulate between the intermediate chamber and the water tank, and a pump to circulate water present in the water tank between the intermediate chamber and the water tank;
a reverse osmosis (RO) filter to purify water that is directly supplied to the electrolytic bath and the water tank of the circulator;
a plurality of valves to control flow of water so that the water supplied from the RO filter is supplied directly to one of the cathode chamber and the water tank; and
a cooling apparatus configured to reduce the temperature of the water in the water tank and comprising any one of a fan and a cooler using a refrigerant or a thermoelectric semiconductor, the water in the water tank being from both the RO filter and the circulator,
wherein the cathode chamber and the intermediate chamber are both provided with an inlet through which water is supplied, and an outlet through which water is discharged,
a cation exchange membrane is provided between the cathode chamber and the intermediate chamber, and
the water tank comprises an outlet through which water stored in the water tank is discharged outside.

2. The apparatus according to claim 1 , wherein the water tank comprises:
a water level sensor to sense a level of water stored in the water tank.

3. The apparatus according to claim 1 , further comprising:
a cation exchange membrane disposed between the anode chamber and the intermediate chamber.

4. The apparatus according to claim 3 , wherein the cathode, the cation exchange membrane provided between the cathode chamber and the intermediate chamber, and the cation exchange resin contact one another.

5. The apparatus according to claim 3 , wherein the cation exchange resin is recycled by reversing the cathode and the anode.
