Auto regenerable water softner dividing water according to temperature}

The present invention relates to a cold / hot water softener for changing and discharging raw water of hard water components to soft water, including a cold / hot water tank filled with an ion exchange resin and a regeneration tank filled with a regeneration material of the ion exchange resin. By using the valve, it is possible to control both the direct water mode for discharging raw water as it is supplied from the outside, the cold / hot soft water mode for discharging cold / hot water, and the regeneration mode for regeneration of the ion exchange resin. It relates to a cold and hot water softener capable of automatic regeneration according to.

Common living water can be divided into soft water (hard water) and hard water (hard water), and soft water such as distilled water or rain water, which is called a single water, is composed mainly of hydrogen (H ₂ ) and oxygen (O ₂ ). While pure and low in hardness, hard water such as groundwater called hard water contains calcium ions (Ca ²⁺ ) and magnesium ions (Mg ²⁺ ), which are high in hardness.

The tap water currently supplied to most households is hard water containing large amounts of calcium ions (Ca ²⁺ ) and magnesium ions (Mg ²⁺ ), especially chlorine (Cl) used in the purification process, and environmental pollution and old pipes Due to the process, harmful heavy metals such as iron (Fe), copper (Cu), tin (Sn), zinc (Zn) and mercury (Hg) are contained.

Although it is not fatal to humans, it is known to combine with fatty acids of soap when washing to produce metal foreign substances, promote skin aging or cause skin diseases such as atopic dermatitis. Water Softner is introduced to convert hard water such as tap water into soft water so that it can be used and is widely used in homes and businesses.

The principle of water softener is to simply replace calcium ions and magnesium ions in hard water with sodium (Na ⁺ ) ions, which are harmless to the human body, and soften them.The soft water tank filled with ion exchange resin of special polymer compound containing sodium ions It is an essential component and includes a regeneration vessel containing regeneration material of ion exchange resin such as salt which, when dissolved in water, generates sodium ions.

1 is a block diagram schematically showing a conventional general water softener, and is a view corresponding to a cold and hot water softener 1 capable of discharging cold and hot soft water by dividing soft water, such as tap water, into cold and hot water. At this time, in the following description, the hard water such as tap water supplied to the water softener is referred to as raw water, which will be used consistently in the present specification.

As shown in the drawing, a typical cold / hot water softener 1 includes a cold regeneration tank 2a and a cold rolling tank 4a connected thereto, a hot regeneration tank 2b and a hot water tank 4b connected thereto, and a plurality of valves V1 and V2. , V3, V4, V5, V6), the cold and hot water tanks 4a and 4b are filled with ion exchange resins containing sodium ions, respectively, and the cold and hot water recycling tanks 2a and 2b are ion exchanged. Salt, the recycled material of the resin, will only be filled during regeneration.

When using soft water, cold source water having a temperature lower than room temperature is supplied to the cold rolled water tank 4a through an empty cold regeneration tank 2a, and discharged into cold rolled water, and hot water having a temperature higher than room temperature is empty. It is supplied to the hot water tank 4b through the regeneration tank 2b and discharged into hot water.

In addition, the general cold and hot water softener (1) includes a plurality of valves for controlling the inflow and outflow of raw water and soft water, the front end of the cold / hot regeneration tank (2a, 2b) agent for controlling the inflow of cold / hot water on-off The first and second valves V1 and V2 are provided, respectively, and the third and fourth valves V3 and V4 for controlling the discharge of cold / hot water on / off after the cold / hot water tanks 4a and 4b. Are respectively provided.

Therefore, the user can use the soft water of the desired temperature by opening the first and second valves V1 and V2 and adjusting the third and fourth valves V3 and V4 appropriately, and the third and fourth valves V3 , V4) can usually be replaced by a power outlet.

On the other hand, when the soft water is used for a long time, since the sodium ions of the ion exchange resin is exhausted, it must be periodically regenerated. At this time, the cold / hot regeneration cylinder (2a, 2b) is provided with separate fifth and sixth valve (V5, V6) for discharging the remaining raw water therein.

Therefore, in order to regenerate the general cold / hot water softener, the user closes all the first to fourth valves V1, V2, V3, and V4, and then opens and closes the fifth and sixth valves V5 and V6 to open and close the cold / hot water regeneration tank 2a. 2b) After the remaining raw water is emptied, salt is added to each of them, and then the first and second valves V1 and V2 are opened to supply raw water to the cold / hot regeneration tanks 2a and 2b. Through this process, regenerated water in which sodium ions are dissolved in the cold / hot regeneration tanks 2a and 2b is generated, which flows into the cold / hot water regenerators 4a and 4b to regenerate the ion exchange resin. Next, the user opens the third and fourth valves V3 and V4 to remove all the salt in the cold / hot regeneration tanks 2a and 2b and the cold / hot water cooling tanks 4a and 4b to complete the regeneration. The user can then use the normal training.
