Abstract

A softening apparatus in which resistance applied between electrodes is decreased to reduce power consumption. The softening apparatus includes a regeneration unit and a softening unit. The regeneration unit includes at least one anode and cathode in a first space which generate regeneration water containing hydrogen ions (H+). The softening unit is disposed in a second space partitioned from the first space and includes an ion exchange body regenerated by the regeneration water.

First claim

What is claimed is:

1. A softening apparatus comprising:
a regenerator comprising a first space defined between an anode and a cathode to generate regeneration water containing hydrogen ions (H+); and
a softener disposed in a second space partitioned from the first space, the softener having an ion exchange body regenerated by the regeneration water; and
at least one channel unit to guide the regeneration water from the first space to the second space,
wherein the first space and the second space are partitioned from each other at the anode, the anode being a boundary between the first space and the second space.

2. The softening apparatus according to claim 1 , wherein the first space and the second space are provided in one housing.

3. The softening apparatus according to claim 1 , wherein the ion exchange body comprises at least one selected from the group consisting of an organic compound comprising an ion exchange resin, an inorganic compound comprising zeolite, and a hybrid compound constituted by a mixture of the organic compound and the inorganic compound.

4. The softening apparatus according to claim 1 , wherein the regenerator further comprises a diaphragm disposed between the anode and the cathode to selectively transmit ions.

5. The softening apparatus according to claim 4 , wherein the diaphragm is selected from the group consisting of non-woven fabric, membrane, and positive ion exchange film.

6. The softening apparatus according to claim 1 , wherein the first space is divided into a plurality of sub spaces by pluralities of anodes and cathodes.

7. The softening apparatus according to claim 1 , wherein the anode and the cathode are formed in a plate shape or a circular shape.

8. The softening apparatus according to claim 1 , wherein the at least one channel unit comprises:
a first channel unit to guide regeneration water generated by the anode in the first space to the second space;
a second channel unit to guide alkaline water generated by the cathode in the first space to be discharged outside; and
a third channel unit to guide condensed water or soft water generated in the second space to be discharged outside.

9. The softening apparatus according to claim 1 , wherein the anode is formed of a porous structure or a mesh structure.

10. The softening apparatus according to claim 1 , wherein the anode is made of an ion exchange material.

11. The softening apparatus according to claim 1 , further comprising a power supply assembly,
wherein the regenerator generates the regeneration water containing hydrogen ions (H+) when power from the power supply assembly is supplied to the anode and cathode.

12. The softening apparatus according to claim 1 , wherein the regenerator further comprises a plurality of diaphragms disposed between the anode and the cathode to selectively transmit ions.

13. The softening apparatus according to claim 1 , wherein the cathode generates alkaline water.

14. A softening apparatus comprising:
a regenerator comprising a first space defined between an anode and a cathode to generate regeneration water containing hydrogen ions (H+); and
a softener disposed in a second space partitioned from the first space, the softener having an ion exchange body regenerated by the regeneration water; and
at least one channel unit to guide the regeneration water from the first space to the second space,
wherein the ion exchange body is disposed in the second space such that the ion exchange body is coupled to one side of the anode via a binder.

15. The softening apparatus according to claim 14 , wherein the binder is at least one selected from the group consisting of an inorganic binder and a porous binder.
