BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water softner, and more specifically, to a single tank type having a single soft water tank, which includes four modes of operation: soft water mode, direct water mode, regeneration mode, and off mode. It relates to the water softener to indicate.

Living water used in our daily life can be divided into soft water (hard water) and hard water (硬水). Training of distilled water, etc., called a double honeydew is hydrogen (H ₂₎ in hard water, the calcium ion with the other hand to a main component of oxygen (O ₂₎ is relatively pure and low hardness, such as ground water, called hard water (Ca ^2+), magnesium ion It contains hardness components such as (Mg ²⁺ ) and has a high hardness.

Currently, tap water, which is supplied to consumers in most households and businesses, is hard water containing a large amount of hardness, and causes chlorine (Cl) used in the purification process, as well as environmental pollution and condensation processes due to old pipes. As a result, heavy metal ions such as iron (Fe), copper (Cu), tin (Sn), zinc (Zn), and mercury (Hg) are contained. Therefore, it is not fatal to the human body, but it is known as a cause of skin disorders such as atopic dermatitis to promote metal aging or to combine with fatty acids of soap.

In this regard, a water softner for converting hard water, such as tap water, into soft soft water was introduced, and is widely used as a general means for obtaining higher quality living water.

The softening principle of the soft water softener is to soften by replacing calcium ions (Ca ²⁺ ) and magnesium ions (Mg ²⁺ ) with sodium ions (Na ⁺ ) in hard water. Ion exchange resins of special high molecular compounds are used, and when they come into contact with hard water, they release sodium ions (Na ⁺ ) instead of adsorbing calcium ions (Ca ²⁺ ) and magnesium ions (Mg ²⁺ ) in water. do. Therefore, the water softener has a soft water tank filled with ion exchange resin as an essential component, and hard water is passed through it to obtain soft water.

On the other hand, training upset when repeated sodium ion (Na ⁺⁾ ion exchange resin is exhausted softening ability is reduced, so it is necessary to restore the softening capacity of the ion exchange resin, sodium ions in the aqueous solution as salt for this purpose (Na ⁺ A separate recycled material is used to produce). Therefore, the water softener is further equipped with a regeneration tank connected to the soft water tank, and recycled materials are added and stored, and when hard water is supplied thereto, regeneration water such as salt water containing sodium ions (Na ⁺ ) is generated, and the regeneration water is a soft water tank. The ion exchange resin is regenerated and discharged in the form of regenerated wastewater.

1 is a block diagram of a general water softener, and corresponds to a cold / hot softener for providing cold / hot soft water through cold / hot hard water. Hereinafter, hard water, such as tap water supplied to a water softener, is called raw water.

As can be seen, a typical cold / hot water softener is a plurality of conduits 31 to 38 and valves V1 to V7 including first and second softening tanks 12 and 14, and first and second regeneration tanks 22 and 24. ), The first and second soft water tanks 12 and 14 are filled with ion exchange resins, and the first and second regeneration tanks 22 and 24 are charged with regenerated materials.

The plurality of pipes 31 to 38 may include first and second tank supply pipes 31 and 32 for supplying cold / hot raw water to the first and second soft water tanks 12 and 14, and first and second soft water. The first and second tank discharge pipes 33 and 34 through which the liquid inside the tanks 12 and 14, for example, cold / hot soft water or regeneration waste water are discharged, and the first and second regeneration tanks 22 and 24 are cooled / cooled. Regeneration water produced in the first and second regeneration water pipes 35 and 36 and the first and second regeneration tanks 22 and 24 to supply the raw water to the first and second soft water tanks 12 and 14. It can be divided into the 1st and 2nd regeneration water pipes 37 and 38 which supply, and these 1st-7th valves V1-V7 are appropriately attached to these lines. The first and second tank supply pipes 31 and 32 and the first and second regeneration water pipes 35 and 36 are respectively connected to the cold / hot water pipes provided in the receivers to receive cold / hot raw water.

Therefore, when cold / hot raw water is supplied to the first and second soft water tanks 12 and 14 by opening the first and second valves V1 and V2, cold / hot soft water is generated by ion exchange of the ion exchange resin. When the third valve V3 connecting the first and second tank discharge pipes 33 and 34 is opened, cold / hot soft water is discharged. In addition, when regeneration of the ion exchange resin is necessary due to repeated softening, the fourth and fifth valves V4 and V5 of the first and second regeneration water pipes 35 and 36 are opened to open the first and second regeneration tanks 22. When the feed water is supplied to (24), regeneration water containing sodium ions (Na ⁺ ) is produced, and the sixth and seventh valves (V6, V7) of the first and second regeneration water pipes (37, 38) are opened to open the first water. And regenerating the ion exchange resin by supplying regeneration water to the second soft water tanks 12 and 14, and the regeneration waste water is opened by opening a third valve V3 at the ends of the first and second tank discharge pipes 33 and 34. To be discharged. In this case, the seventh valve is usually replaced by a power outlet.

However, the above-mentioned general cold / hot water softener exhibits some disadvantages. The first and second regeneration tanks 22 and 24 including the first and second softening tanks 12 and 14 are integrally formed to be bulky and installed. It shows a problem that requires a large area. Therefore, if you want to soften only one of the cold / hot water or if there is only one water pipe in the installation place, it is practically impossible to use, and considering that the installation place of the water softener is a narrow space such as a bathroom, It may cause a lack of used space.

In addition, the general water softener has a high possibility of malfunction or failure due to excessively complicated regeneration of the ion exchange resin, and there is no specific method for accurately determining the regeneration time of the ion exchange resin. Due to the fact that it depends entirely on the calculation of the period, unnecessarily frequent regeneration causes waste of recyclable materials or misses the proper regeneration time, which often degrades the performance and life of the ion exchange resin.

Accordingly, the present invention has been made to solve the above problems, as a single tank type water softener that can selectively soften any one of the cold / hot raw water, the user can easily install even in a small space Its purpose is to provide a water softener that can be used easily and easily by anyone, because the overall method of use is simple, and the regeneration time of the ion exchange resin can be objectively and accurately determined.
