Description

Completely regenerative water softener having control valve gear of flow rate and regeneration tank with one-touch open and close device}

The present invention relates to a water softener that makes soft water suitable for bathing and washing by ion-exchanging raw water such as tap water. More specifically, a softening tank having respective inlets and outlets installed therein, and a regeneration tank into which reclaimed materials are added. Is integrally coupled to the lower part of the softening tank, so that a more complete softening process can be carried out, and a softener capable of effectively regenerating the ion exchange resin.

1 is a sectional view of a conventional general soft water tank, in which hard water flows into an upper hard water inlet and is introduced by an ion reaction with an ion exchange resin (4) filled in an upper portion of the wire mesh (3) in the soft water tank (2). After Ca and Mg in hard water were removed and converted into soft water, the water was discharged through the soft water outlet of the lower part of the soft water tank 2.

In the prior art, the reason why the hard water flows down from the top is to obtain the ion exchange reaction effect as a simpler structure by using water flowing down by the influence of gravity. The reaction was not so large that a satisfactory ion exchange effect could not be obtained.

In order to regenerate the ion exchange resin, a regeneration agent (generally sodium chloride) is added to remove the cations adsorbed by the ion exchange resin and discharge it to the outside, thereby regenerating soft water capacity. This was because it could not be stirred with the resin and simply flowed through the pores between the ion exchange resins from the top to the bottom to sufficiently remove the cations adsorbed on the ion exchange resins.

The present applicant is shown in Figure 2 prior art integrating the soft water tank and the regeneration tank proposed to improve the problems of the prior art as described above (Patent Application No. 10-2001-0036118).

The technical features of the application is first, the structure of the regeneration tank, the hard water flowing into the lower portion of the regeneration tank 20 separated from the soft water tank 10 through the separator 24 for partitioning the space in the regeneration tank exits the outlet To discharge through the pipe to the soft water tank (10), and second, as a structure of the soft water tank to the hard water flowing into the soft water tank (17) to the lower part of the soft water tank (17), the cavity in the soft water tank ( After the ion exchange reaction with the ion exchange resin (16) filled in 18) is to discharge the soft water to the water outlet pipe (14) at the top.

The reason for choosing the above structure is to separate the regeneration tank from the soft water tank, and to pass the hard water through the separator and the connecting pipe, so that the added regenerant can be melted more completely and flow into the regeneration tank. It is intended to maximize the surface area of the ion exchange reaction with the ion exchange resin filled in the soft water tank by flowing under the soft water tank.

The present invention is to further improve the technology proposed by the present applicant in order to solve the problems of the prior art as described above, it is an object of the present invention to provide a water softener that can further improve the efficiency of the regeneration process.

Another object of the present invention is to provide a water softener capable of ensuring a simple and hermetic seal by incorporating a regeneration agent that requires frequent replacement into a regeneration tank in a one-touch type.

Still another object of the present invention will be apparent from the following detailed description and drawings.

Each of the engaging protrusions 320 and the engaging protrusion coupling grooves of the regeneration tank body 310 is configured as six, but is not limited thereto and may be changed as necessary. It is apparent that other soft materials such as rubber can be used.

7 is a control valve 400, Figure 7a is a cross-sectional view of the control valve 400 is mounted in the body portion 200 of the upper portion of the regeneration tank 300 and the lower of the soft water tank 100, Figure 7b is The configuration of the control valve 400, and Figure 7c shows the flow rate control port 420, respectively.

The control valve 400 is a switch 410, the shaft 470 connected to the switch 410, is connected to the shaft 470 is located in the inner center of the hard water T-type ripple 210 of the body portion 200 Consisting of the flow control port 420 (Fig. 7b), the inside of the flow control port 420 is a cross-shaped passage formed of the water outlet hole 430, the hard water inlet hole 440 and the regeneration solution inlet hole 450 It consists of (FIG. 7C).

The regeneration solution inlet 450 is relatively small compared to the water extraction hole 430 and the hard water inlet hole 440, the description thereof will be described in detail in the operation of the water softener.

The flow control port 420 has the same diameter as the inner diameter of the hard water T-type ripple 210, the water inlet 440 and the regeneration solution inlet 450 is regenerated by the 180 ° rotation of the switch 410 It is connected to the outlet port (inner circle out of the two circles shown in the center of Figure 6b) through the lid 330 of the tank.

As the material of the flow regulating port 420, it is preferable to prevent wear due to friction with a pipe used for piping because it is soft, such as silicon, but is not limited thereto.

It is obvious that each component constituting the softener such as the softening tank 100, the body 200, and the regeneration tank 300 may be a metal product or a resin product by injection molding as in the prior art.

Looking at the operation structure of the water softener according to the present invention having the configuration as described above with reference to FIG.

In the water softener according to the present invention, the fluid movement is classified into a raw water process that undergoes only a training process and a regeneration process that undergoes a regeneration process by adding a regenerant. On both sides), the hard water flows into the regeneration tank 300, passes through the regeneration tank lid, and through the hard water inlet hole 440 and the water outlet hole 430, through the second joint part 150 of the soft water tank, the first joint part 160. Flows into).

Hard water introduced from below rises while pushing the ion exchange resin filled in the first cavity 160 to undergo ion exchange reaction and flows into the hollow pipe 120 through the water extraction mesh 130, and the soft water T-type ripple 250 ) Are combined and discharged to the outside.

When the regeneration capacity of the ion exchange resin is lost due to repeated ion exchange reactions, the regeneration tank body 310 is rotated and separated from the lid 330 to refill the regenerant, and then the switch 400 is regenerated. When rotated 180 ° to the display portion described in the regeneration process not shown), the regeneration solution inlet hole 450 of the flow control port 420 is connected to the hole of the lid 330 of the regeneration tank to the solution in which the regenerant is dissolved As the raw water process proceeds, the regeneration capacity of the ion exchange resin is restored.

In the regeneration process, the regeneration solution inlet 450 has a relatively small inner diameter compared to the hard water inlet 440, so that the flow rate of the dissolved regenerant solution is very small. The reason for making the inner diameter of the regeneration solution inlet hole 450 very small is to completely dissolve the regenerated reclaimed material and transfer it to the soft water tank to more efficiently regenerate the soft water tank.

Although one preferred embodiment of the water softener according to the present invention has been described above, it will be understood that the present invention is not limited thereto and may be variously changed or modified within the scope of the technical idea of the present invention.

According to the present invention as described above, when the regenerant is added to the regeneration tank can be made in one-touch manner can be replaced more easily.

In addition, in the regeneration of the ion exchange resin, there is an advantage that the complete regeneration is possible by adjusting the inner diameter of the inlet hole of the flow control port.
