Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a regeneration tank using regeneration tablets,

The present invention provides a regenerator using a tablet-type regenerant and a regenerated water generating method using the regenerator as a regenerator for a water softener.

In the case of tap water (hereinafter referred to as "hard water"), a large amount of chlorine ion is contained in the purification process, and when the water of the tap water passes through the old pipe or the raw water of the tap water itself is polluted, various heavy metals such as iron, zinc, lead and mercury Ions. These ionic components can be combined with fatty acids of soap, in particular, to produce metallic foreign substances, which can contact the skin and cause allergies or skin aging.

To prevent this, a water softener is used which generates soft water by passing hard water through strongly acidic cations such as Na + and exchanging hardness components Ca2 + and Mg2 + with Na +.

To this end, the water softener is provided with an ion resin tank in which water containing sodium ions is stored. However, when the ionic resin tank is continuously used, sodium ions in the ionic resin tank are continuously consumed. Therefore, in order to fill the ionic resin tank with sodium ions at regular intervals, regenerated water containing sodium ions is produced in the regenerator, It must be passed through the tank.

To this end, the regeneration vessel is filled with a regenerant capable of producing regenerated water containing sodium ions dissolved in the incoming raw water. As the regenerant, a substance such as salt containing an NaCl component is mainly used.

The regenerant can be classified into a block type such as a brick, or a powder type in the form of a powder or a small ball depending on its form.

However, in the case of the block type regenerant, when the regenerant of the other part, particularly the part to which the raw water is introduced for the regeneration, melts and disappears even though some of the blocks remain in the regeneration process, It was reported frequently.

In the case of the powder type regenerant, it is not easy to use only a desired amount of the regenerant, and the concentration (hereinafter referred to as "salinity") of regeneration water is not constant and the efficiency is low.

Particularly, in the case where the residue is not cleanly drained in the regeneration tank, which is a regenerated water tank, even when any regenerant is used, it has been reported that the concentration is changed or contamination is mixed with the regenerated water to be produced later.

On the other hand, depending on the method of dissolving the regenerant, it may be classified into a gravity type in which raw water is introduced by gravity and a hydraulic type in which water is melted according to the inflow pressure of raw water.

However, in the gravity type, that is, in the case of the automatic regeneration method, the time required varies depending on the salinity difference in which the regenerant is melted for each number of regeneration, and it is difficult to use the powder regenerant in the case of the hydraulic pressure regime.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems.

Specifically, a tablet type regenerant is proposed to overcome the problems of the block type regenerant and the powder type regenerant.

Particularly, while using a tablet-type regenerant, the problem of contamination is solved by appropriately using residual water, and at the same time, a uniform saltiness is to be achieved.

One embodiment of the present invention for solving the above problems is a regenerator 200 of a water softener capable of injecting a tablet type regenerant and generating regenerated water, A passage member 230 for partitioning the inside of the regeneration tank 200 into an upper regenerant storage unit 251 and a lower side buffer 252; And a raw water inflow section 220 in which the upper end of the raw water is discharged is located in the regenerant storage section 251. The regenerated water located in the regenerant storage section 251 is discharged from the passage member 230 And flows into the buffer 252. The buffer 252 is connected to the regenerator through the regenerator.

The regenerant inlet valve 210 is located above the regenerator 200 above the regenerant reservoir 251 and the regenerant inlet valve 210 is closed when the regenerant inlet valve 210 is closed. It is preferable that the residual water stored in the buffer 252 flows to the ion resin tank 100 by the water pressure of the raw water when the raw water flows into the raw water inflow base 220 at a predetermined water pressure Do.

In addition, the raw water inlet 220 is preferably connected to a raw water inflow line 291 through which the raw water flows from outside the regenerator 200.

Also, it is preferable that a check valve 292 is provided on a line connecting the ionic resin tank 100 of the water softener and the buffer 252.

Further, it is preferable that a drain valve 293 is provided in the line through which the buffer 252 is connected through the residual drain of the water softener.

It is preferable that the tablet-type regenerant injected into the regenerator 200 does not pass through the passage member 230.

Another embodiment of the present invention for solving the above problems provides a water softener provided with the above-described regeneration tank (200).

Further, a method of generating regenerated water in the water softener may include the steps of: (a) injecting regenerant into the regenerant storage unit 251 of the regeneration reactor 200; (b) the raw water is introduced into the regenerant storage part (251) of the regeneration tank (200) through the raw water inflow part (220), and the regenerant is melted in the raw water to generate regenerated water; (c) collecting the regenerated water generated in the regenerant storage unit 251 through the passage member 230 and collecting the regenerated water in the buffer 252; And (d) supplying a portion of the regenerated water collected in the buffer (252) to the ion resin tank (100) through the check valve (292).

In the first mode, the step (c) includes the steps of: (c ') selecting one of the first mode and the second mode according to a predetermined method when the softener is in a playback mode; , It is preferable that the regenerated water newly generated in the regenerant storage unit 251 in the first mode is mixed with the residual water.

In the second mode, before the step (c), (c1) the drain valve (293) is opened and the remaining water in the buffer (251) is discharged to the residual drain tank; And (c2) generating a reproduction number input signal.

The predetermined method for selecting either the first mode or the second mode may further include the step of determining whether the accumulated flow rate flowing into the regeneration tank 200 measured by the raw water flow rate inflow line 291 is less than a predetermined flow rate It is preferable that the first mode is selected and the second mode is selected when the flow rate is equal to or higher than the predetermined flow rate.

Since the tablet-type regenerant is used in the present invention, the problem that only a part of the block-type regenerant is melted is solved, and the problem that the pressure regulator of the powder type regenerant can not be applied is solved. Accordingly, the present invention adopts a semiautomatic hydraulic water softener.

In addition, since the raw water for generating the regeneration water is introduced by a certain amount for a predetermined time at a constant water pressure, it is possible to generate regeneration water that maintains the salinity constant. According to the experiment of the present inventor, it has been confirmed that an appropriate salinity of about 9 to 11% is steadily maintained.

The raw water flows into the regenerator in a vacuum state at a constant water pressure, and the regenerated water naturally moves to the ion resin tank by the force. Here, since the check valve is adopted, the problem that the water flows into the regenerator from the ion resin tank to dilute the regenerated water is also solved.

The residual water remaining in the regenerator is mixed with the newly regenerated water for a certain period of time without any problem of contamination. However, if it is determined that a certain amount of raw water has flowed into the regenerator after a certain time, The problem of pollution is also solved because it can be discharged into the cylinder.

As the regeneration vessel is partitioned into two by the passage member, the regenerant does not meet the raw water, regeneration water or residual water unless the regeneration water producing condition is satisfied, thereby preventing the regeneration agent from unnecessarily melting.

Explanation of water softener

1 shows a water softener according to the present invention. The cover is not shown for the sake of explanation.

The water softener according to the present invention includes an ion resin tank 100, a regenerator 200, a timer and a ceramic disk switching valve 300, a water inlet 400 and a water outlet 500.

The ionic resin tank 100 is provided with an ionic resin. It is filled with sodium ions.

When the raw water flows into the regenerator 200, regenerated water containing sodium ions is generated and flows into the ionic resin tank 100, so that the ionic resin tank 100 are filled with sodium ions.

The timer and the ceramic disk switching valve 300 change the flow path to select one of the training mode, the raw water mode, and the regeneration mode, and the timer allows the regeneration mode to be maintained only for a predetermined specific time.

The user can operate any of the training mode, the raw water mode, and the regeneration mode by operating the operation portion on the outside of the water softener. The timer and the ceramic disk switching valve 300 are operated to change the flow path according to the result.

When the user selects the training mode, the training water is discharged through the heading unit 500. In this case, the raw water introduced into the water softener through the water inlet 400 through the timer and the ceramic disk switching valve 300 flows to the ionic resin tank 100 to soften the hard water, and the soft water is supplied to the water outlet 500 Lt; / RTI >

When the user selects the raw water mode, the raw water is directly discharged from the water outlet 500. That is, the raw water flowing into the water softener through the water intake part 400 by the timer and the ceramic disk switching valve 300 is discharged directly to the water outlet part 500 without directly passing through the ionic resin tank 100.

When the user selects the regeneration mode, the raw water that has flowed into the inlet portion 400 by the timer and the ceramic disk switching valve 300 flows into the regenerator 200 to generate regenerated water, which is supplied to the ionic resin tank 100 So that the ionic resin is filled with sodium ions and then discharged to the outside.

Here, by the timer of the timer and the ceramic disk switching valve 300, the regeneration mode operates for only about 15 minutes. Further, the first mode and the second mode are selectively operated. This will be described later in the reproduction number generation method.

On the other hand, a detachable residual drain pipe (not shown) is located in the regenerator 200. The drain valve 293 is connected to the drain valve 293 of the regeneration tank 200. When the residual drainage tank (not shown) is in communication with the drain valve 293 of the regeneration tank 200 So that residual water in the regeneration tank 200 can be cleanly discharged into a residual water drain (not shown), which can be separated from the water softener and separated from the water softener. The contamination problem caused by remaining drainage in the regeneration tank 200 due to the drain valve 293 and the residual drain pipe (not shown) can be solved.

Regenerator  Explanation

Hereinafter, the regenerator 200 according to the present invention will be described with reference to Figs. 2 and 3. Fig.

When the regenerator 200 is viewed from the outside, the regenerant inlet valve 210 is located at the upper portion and the raw water inflow line 291, the check valve 292, and the drain valve 293 are located at the lower portion.

The regenerant feed valve 210 is opened to feed the regenerant into the regenerator 200, and is closed after the completion of the feed. The inner space of the regenerator 200 is closed so that the vacuum state can be maintained.

Here, the regenerant is preferably a tablet type. As described above, in the case of the block type, there is no problem that the part is melted and the part is not melted. In the case of the tablet type, there is no problem of melting only partly. It is possible. As will be described later, the regenerator 200 according to the present invention employs a semi-automatic hydraulic pressure regulator.

The constant flow inflow line 291 is a line connecting the inlet unit 400 and the raw water inflow base 220 to supply a predetermined amount of raw water to the regenerator 200 for generating regenerated water.

The check valve 292 is provided in a line connecting the regenerator 200 and the ionic resin tank 100. Concretely, a space for storing the regenerated water is provided in a line connecting the buffer 252 and the ion resin tank 100, which will be described later. In the absence of the check valve 292, conversely, soft water can flow from the ionic resin tank 100 to the regenerator 200, which makes it difficult to control the salinity of the regenerated water.

The drain valve 293 allows remaining water in the regeneration tank 200 to flow into a residual water drain (not shown) when the user opens the drain valve 293.

When the regenerator 200 is viewed from the inside, a large number of through holes are positioned inside the regenerator 200 so as to allow fluid communication between the upper and lower portions. The inside of the regenerator 200 is connected to the upper regenerant reservoir 251 and the lower The buffer member 252 of FIG.

The passage member 230 may be in the form of being mounted on the step 231 in the regenerator 200.

The size of the through-hole of the through-hole member 230 is smaller than that of the tablet-like regenerant. In this way, the tablet type regenerant remains only in the regenerant storage unit 251, which is the upper space of the passage member 230, and the regenerated water generated by the mixing of the regenerant flows through the passing member 230, (252).

The raw water inflow line 220 is connected to the raw water inflow line 291 at the lower end to flow raw water and the upper end to the raw water inflow port 220 ).

The raw water inflow base 220 is protruded by a predetermined length from the passing member 230. When the regenerant feed valve 210 is closed as described above, the inner space of the regenerator 200 is maintained in a vacuum state. The raw water introduced through the raw water inlet 220 is supplied to a predetermined water pressure The regenerated water in the buffer 252 is automatically discharged to the ionic resin tank 100 by the force of the raw water flowing into the ionic resin tank 100.

At the same time, the raw water introduced into the regenerant storage unit 251 through the raw water inflow base 220 at a preset water pressure causes the regenerant to melt smoothly.

Here, the predetermined water pressure may be 0.7 to 3.0 kgf / cm < 2 >, and this water pressure may be maintained through the fitting portion provided in the constant flow inflow line 291. [

Play  Explanation of how to create

First, the reproduction number generating method according to the present invention can be divided into a first mode and a second mode.

The first mode is a mode in which residual water remaining in the buffer 252 of the regeneration tank 200 is utilized as regeneration water. It is not necessary to drain residual water remaining in the buffer 252 of the regenerator 200. The residual water remaining in the buffer 252 (i.e., the regenerated water) starts to flow into the ionic resin tank 100 as the raw water is introduced into the regeneration tank 200 at a predetermined water pressure as described above, The reproduction number is mixed with the remaining number of remainders.

The second mode is a case where it is determined that it is necessary to discard the remaining number. In this case, after the drain valve 293 is opened to flow the residual water through the residual drain pipe (not shown), the user can remove the remaining water by separating the residual drain pipe (not shown) from the water softener.

It is preferable that the first mode and the second mode are determined by using the cumulative flow rate flowing into the regenerator 200.

In one embodiment of the present invention, raw water is introduced at a rate of 140 to 200 ml / min in one-time regeneration, and the volume of the regenerator 200 is regenerated It is designed to contain the agent.

Accordingly, by accumulating the flow rate of the raw water flowing into the regeneration tank 200 by a separate totalizer (not shown), it is determined whether or not the raw water of 16,800 to 24,000 ml has flown into the regeneration tank 200, more preferably, It is checked whether the raw water has flowed into the regenerator 200. If it is less than the predetermined value, the first mode is operated, and if it is abnormal, the second mode is operated.

Here, the reference flow rate, which is exemplarily shown as 20,000 ml, may be varied depending on the volume of the regenerator 200, the regeneration time, the raw water inflow rate, and the like.

It is necessary to manually or automatically open the drain valve 293 in the second mode and separate and discharge the residual water drain (not shown) to the user, while the second mode requires no other operation At the same time, it is possible to generate a regenerant injection request signal indicating that the regenerant is required to be newly injected. If a regenerant input request signal is generated, a separate notification light will be turned on to the user.

(Finally, the regenerator according to the present invention is a semi-automatic hydraulic regenerator.)

Hereinafter, a method of generating a regenerated water of a water softener according to the present invention will be described with reference to FIGS.

(S100, Fig. 4A) into the regenerator 200 which is cleanly emptied. Passes through the passage member (230), and thus is stored only in the regenerant storage unit (251). The vacuum state is maintained after the regenerant is charged.

When the regeneration mode is selected, the timer and the ceramic disk switching valve 300 communicate the water inlet 400 and the regeneration tank 200 to the raw water flow inflow line 291 and the time measurement is started.

The raw water flows into the regenerant storage unit 251 filled with the regenerant through the water inlet unit 400, the constant water flow rate inflow line 291 and the raw water inflow zone 220 from the water inlet at predetermined water pressure. And the regenerant is melted in a wide range smoothly as it flows into the predetermined water pressure (S300).

As soon as the raw water is introduced, the regenerant in the regenerant storage unit 251 is melted in the raw water to generate regenerated water, and the regenerated water is collected by the buffer 252 through the passing member 230 by its own weight (S400, 4b).

During the introduction of the raw water for about 15 minutes, the regenerated water continues to be generated and descended and collected in the buffer 252. The regenerator 200 is still in a vacuum state. Therefore, the regenerated water collected in the buffer 252 flows to the ion resin tank 100 by the force of the raw water flowing into the predetermined water pressure (S500, FIG. 4C).

After about 15 minutes, one playback mode is completed. Specifically, the first mode is completed.

After the completion of the first mode, the tablet type regenerant in the regenerant storage unit 251 is partially melted and its height is lowered, and the buffer 252 is also left with a residue (FIG. 4D).

When the ion resin tank 100 is filled with sodium ion by performing the one-time regeneration mode, the user can use the water softener again for a certain period of time. Thereafter, when it is determined that the ion resin tank 100 needs to be filled again, the regeneration mode is performed again.

When the raw water starts to flow into the regeneration tank 200 (S600), it is determined whether the cumulative flow amount flowing into the regeneration tank 200 measured by the totalizer is a preset flow rate (S700) .

If the cumulative flow rate flowing into the regeneration tank 200 is less than the preset flow rate, the first mode is performed again. That is, raw water is introduced into the regenerator 200 through the raw water constant flow inflow line 291 by the timer and the ceramic disk switching valve 300, the time measurement is started, and the raw water is fed through the raw water inflow band 220 The regenerated water is introduced into the regenerant storage unit 251 at a prescribed water pressure, and regenerated water is generated. The regenerated water is collected in the buffer 252 through the passage member 230. In this case, the generated reproduction number is generated in the previous reproduction mode (first mode) and mixed with remaining wastes in the buffer 252 (FIG. 4E).

The regenerated water mixed with the residual water flows to the ionic resin tank 100 by a predetermined water pressure at which the raw water flows (Fig. 4F).

After about 15 minutes, when one reproduction mode is completed, the remaining number is also left (Fig. 4G).

And the second mode is performed when the cumulative flow rate flowing into the regenerator 200 reaches a preset flow rate. The drain valve 292 is opened manually or automatically to discharge the remaining amount to the residual drainage tank (not shown), thereby informing the user that it is necessary to separate and drain the residual drainage tank (not shown) (S800, Fig. 4H), which indicates that a new input is required.

That is, when the second mode is completed, as shown in FIG. 4A, the regenerator 200 can not be regenerated and can not be used again.

While the present invention has been described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the following claims.
