In general, tap water (hard water) contains a large amount of chlorine components used in the purification process. It also contains various heavy metals (ions) such as iron, zinc, lead, and mercury which are harmful to human body due to water pollution caused by factors such as aging pipes. .

Such tap water is not fatal to the human body, but if used intact, the metal ion contained in the water and the fatty acid of the soap are combined to form a metallic foreign substance on the user's skin. Such a metallic foreign matter causes various skin diseases such as allergy again It is known to be a direct cause of accelerated aging of the skin.

To prevent this, water softener is widely used for washing and cleaning by exchanging water hardness components Ca2 + and Mg2 + with Na + in a strong Na + cation exchange resin to make soft water.

Such a water softener is composed of a principle that calcium ions and magnesium ions contained in hard water are replaced with sodium ions (Na +). Therefore, the water softener is equipped with an ion exchange resin containing a special polymer compound containing sodium ions, And a regeneration vessel containing an ion exchange resin recycling material such as salt for sodium ion production.

That is, in the water softener, the water is kept in contact with the ion exchange resin while the tap water is continuously stored in the soft water bottle in the state of storing a large amount of fine ion exchange resin in the form of ball.

At this time, since the Na + component is significantly reduced due to continuous contact with the tap water, the ion exchange resin is required to regenerate a predetermined regeneration process for the ion exchange resin such as a salt water containing NaCl component need.

In the conventional water softener, a regenerant is put into the regeneration tank when regenerating the ion exchange resin, the regeneration agent is made to pass through only a certain part of the regenerant, and then the regenerated water is regenerated by dropping the regenerated water into the soft water tank.

However, such a method has a problem that the regeneration efficiency is not constant due to the influence of water temperature and water temperature depending on seasons.

Therefore, a method for solving such problems is required.

The stop mode is a mode for a series of dissolution actions for adjusting the concentration of the regeneration water in the regeneration tank 10 to a concentration necessary for regeneration of the ion exchange resin contained in the first tank 20 and the second tank 30, It is an operating condition that prevents all the pipe connections from intercepting each other to prevent the flow of water.

The rinsing mode regenerates the ion exchange resin accommodated in the first tank 20 and the second tank 30 and then flows into the first tank 20 and the second tank 30 to regenerate the regenerated water passing through the inside of the first tank 20 and the second tank 30. [ The first and second soft water recovery pipes 113a and 113a and the discharge piping pipe 114 are connected to each other and the first and second water supply pipes 111b and 111b are connected to each other, The first original export pipeline 112b and the second original export pipeline 111a and the second original export pipeline 112a, respectively.

The regeneration outgoing mode is a mode in which the regeneration water in the regeneration tank 10 is passed through the first tank 20 and the second tank 30 while the regenerated water in the first tank 20 and the second tank 30 The first and second regeneration regeneration importing sections 113b and 113b and the discharge piping section 114 are connected to each other so that the regeneration resin can be regenerated and the regeneration water can be completely discharged to the outside, .

The structure of the water softener according to the present embodiment has been described above, and the ion exchange resin regeneration method of the water softener using the water softener will be described below.

The method for regenerating an ion exchange resin of a water softener according to the present invention includes the steps of (a) operating the flow path switching valve module (100) in a regeneration intake mode to replenish raw water in the regeneration tank (10) (B) detecting a supply amount of the raw water with respect to a total amount of the regenerant contained in the regenerant, when the supply amount of the raw water with respect to the total amount of the regenerant is within an error range with respect to a preset set value, (C) operating the channel switching valve module (100) in the regeneration outgoing mode to stop the regeneration water contained in the regeneration tank (10) from flowing into the first tank (20) and the second tank (D) to the outside through the pipe.

Referring to FIGS. 9 and 10, in step (a), raw water W ₁ is filled in the regeneration tank 10 by activating the flow path switching valve module 100 in the regeneration intake mode. Thus, the raw water W ₁ is converted into the regeneration water W ₂ by the regeneration material P ₁ contained in the regeneration tank 10.

In the step (d), the channel switching valve module 100 is operated in the regeneration outgoing mode so that the regeneration water W ₂ contained in the regeneration tank 10 is supplied to the first tank 20 and the second tank 20, (30) and discharged to the outside.

Views by the present process (W ₂₎ is the regeneration of the ion exchange resin (P ₂₎ is made as they pass between the between the ion-exchange resin (P _2), the first tank 20 and second tank, The regenerated water W ₂ that has completely passed through the regeneration tank 30 is delivered to the discharge pipe port 114 through the first regeneration regeneration import port 113b and the second regeneration regeneration import port 113a and then discharged to the outside.

(B) detecting the supply amount of the raw water with respect to the total amount of the regenerant contained in the regeneration tank 10 in the process of operating the regeneration intake mode as in the step (a) When the supply amount of the raw water satisfies the error within the predetermined range with respect to the predetermined set value, the supply of the raw water is interrupted (c).

That is, in the case of the present invention, the supply amount of the raw water can be adjusted in consideration of the total amount of regenerant contained in the regeneration tank 10. At this time, the supply amount of the raw water with respect to the total amount of the regenerant may be set within a predetermined error range at a saturation concentration of the regenerant, that is, the minimum amount in which the entire regenerant contained in the regeneration tank 10 can be dissolved have.

In this supersaturated automatic regeneration system, a predetermined amount of raw water is supplied to the regeneration tank 10 filled with the granular regenerant P ₁ , and the regenerated liquid W ₂ supersaturated instantaneously flows slowly and naturally, The regeneration liquid can be supplied only to the regeneration tank, and the regeneration efficiency can be always maintained by regenerating the regeneration liquid W ₂ made into a saturated state irrespective of the used water pressure and the water temperature.

Such a process can be performed by the control module 200. The control module 200 may be provided separately from the water softener, or may be installed in the water softener.

Between step (c) and step (d), the flow path switching valve 100 is operated in the stop mode until the regenerant (P ₁ ) is completely dissolved in the raw water (e ). ≪ / RTI >

The reason for doing this is to ensure sufficient time for the regenerant (P ₁ ) to be completely dissolved in the raw water at the saturated concentration.

Meanwhile, the water softener according to the present embodiment may further include a shielding module for smoothly performing the reproducing method. 11 and 12 are views showing the appearance of the shielding module 40 according to the present embodiment.

11 and 12, the shielding module 40 is installed between the regeneration tank 10 and the first tank 20 and between the regeneration tank 10 and the second tank 30, Respectively. Although only the first tank 20 is shown as an example in the drawing, it is needless to say that the shielding module 40 may be applied to the second tank 30 as well.

The shielding module 40 is configured such that the raw water introduced through the channel switching valve module 100 passes through the raw water supply port 116 without passing through the regeneration tank 10, 2 tank 30, a fluid flow path between the regeneration tank 10 and the first tank 20 and a fluid flow path between the regeneration tank 10 and the second tank 30, It serves to shield the path.

That is, when the channel switching valve module 100 is in the training mode, the introduced raw water is directly supplied to the first tank 20 and the second tank 30 by bypassing the regeneration tank 10. At this time, the shielding module 40 shields the fluid flow path to prevent the raw water supplied into the first tank 20 and the second tank 30 from flowing back to the regeneration tank 10.

On the contrary, when the flow path switching valve module 100 is in the regeneration outgoing mode, the shielding module 40 can regenerate the regeneration water from the regeneration tank 10 to the first tank 20 or the second tank 30 The fluid flow path can be opened.

Specifically, in the present embodiment, the shielding module 40 includes a first flow path forming portion 41, a second flow path forming portion 42, and a shielding member 50.

The first flow path forming portion 41 is a component formed on the first tank 20 and the second tank 30 to form a fluid flow path. The second flow path forming portion 42, Is a constituent element formed in the lower portion of the regeneration tank 10 to form a fluid flow path.

At this time, the first flow path forming portion 41 and the second flow path forming portion 42 are spaced apart from each other by a predetermined distance, and a connecting flow path 43 may be formed therebetween. The regeneration water accommodated in the regeneration tank 10 passes through the connection passage 43 and the first flow path forming portion 41 via the second flow path forming portion 42 and flows into the first tank 20 or And may be introduced into the second tank 30.

The shielding member 50 is vertically movable in the connection passage 43. Particularly, the shielding member 50 shields the fluid flow path of the second flow path forming portion 42 during the upward movement and opens the fluid flow path of the second flow path forming portion 42 during downward movement do.

That is, when the shielding member 50 is moved upward, the regenerated water stored in the regeneration tank 10 is not introduced into the first tank 20 or the second tank 30, The regeneration water contained in the regeneration tank 10 can be introduced into the first tank 20 or the second tank 30. In this case,

12, the structure of the shielding module 40 is shown in more detail.

12, the first flow path forming portion 41 includes a plurality of first protrusions 41a protruding upward. At this time, a through hole 41b is formed between the adjacent first protrusions 41a, . The second flow path forming portion 42 includes a second protrusion 42a projecting downward. The shielding member 50 includes a shielding portion 51 that contacts the first protrusion 41a when moving downward and contacts the second protrusion 42a when the shielding member 50 moves upward.

Accordingly, when the shielding member 50 is moved upward, the shielding portion 51 completely closes the second protrusion 42 to shield the flow path of the fluid, and when the shielding member 50 moves downward, The flow path of the fluid is opened by the through hole 41b although the shielding portion 51 contacts the first protrusion 41a.

The shielding member 50 may be formed with an insertion portion 52 which protrudes upward from the shielding portion 51 and is inserted into the second flow path forming portion 42. [

The insertion portion 52 is fitted in the second flow path forming portion 42 so as to minimize the lateral clearance of the shielding member 51. In particular, in the present embodiment, the central portion 52a and the central portion 52a And a plurality of radially projecting portions 52b projecting radially from the base portion 52a.

The reason why the insertion portion 52 has such a shape is that the flow path of the fluid can be opened while the shield member 50 is downward. That is, the fluid flow groove 53 through which the fluid can pass is formed between the plurality of radial protrusions 52b, so that the regenerated water contained in the regeneration tank 10 can be regenerated by the insertion portion 52, The fluid can be flowed downward through the fluid flow groove 53 even in a state where it is inserted into the portion 42.

FIG. 13 is a view of a water softener according to an embodiment of the present invention, showing a state of a shielding module 40 in a reproduction outgoing mode, FIG. 14 is a diagram illustrating a water softener according to an embodiment of the present invention, And the module 40 shown in FIG.

13, when the water softener of the present embodiment is in the regeneration outgoing mode, the regeneration water contained in the regeneration tank 10 flows through the second flow path forming portion 42, the connecting flow path 43, (41) and flows into the first tank (20) or the second tank (30).

Such a process may be performed as the shielding member 50 is kept downward by the pressure of the replenishing water.

14, when the flow path switching valve module 100 is in the training mode, the introduced raw water passes through the regeneration tank 10 to bypass the first tank 20 and the second tank 30 And is directly supplied to the first tank 20 and the second tank 30 through a raw milk feeding tongue 116 connected to one side of the first tank 20 and the second tank 30.

At this time, the shielding member (50) floats up by the raw water supplied in the first tank (20) and the second tank (30), and the shielding portion (51) The second protrusion 42a of the second protrusion 42 is in close contact with the second protrusion 42a.

Accordingly, in the present embodiment, it is possible to prevent the regeneration water from being unnecessarily introduced into the first tank 20 and the second tank 30 in the training mode, and in the regeneration outgoing mode, 1 tank 20 and the second tank 30, respectively.

It will be apparent to those skilled in the art that the present invention can be embodied in other specific forms without departing from the spirit or scope of the invention as defined in the appended claims. It is obvious to them. Therefore, the above-described embodiments are to be considered as illustrative rather than restrictive, and the present invention is not limited to the above description, but may be modified within the scope of the appended claims and equivalents thereof.
