Description

Manufacturing unit for regenerating water in water softeners {Manufacturing unit for regenerating water provided in water softening apparatus}

The present invention relates to a regenerated water production unit of a water softener, and more specifically, the change in the concentration (salin) of the regenerated water is small, occupies a small space, and is convenient to replenish the regenerator (salt), and the foreign matter contained in the regenerant. The present invention relates to a regeneration water production unit which can prevent movement to the ion exchange resin and which is convenient for internal cleaning.

In general, living water can be divided into soft water and hard water. Soft water, also called sweet water, is relatively pure and low in hardness, while hard water, such as ground water, called hard water, contains calcium and magnesium ions. Because of its hardness.

Currently, tap water supplied to most households is hard water containing a large amount of calcium ions and magnesium ions. Especially, iron, copper, tin, zinc, Since it contains a lot of heavy metal ions such as mercury, the tap water, although not fatal to the human body, binds to fatty acids of soap during washing to produce metal foreign substances, promote skin aging and cause skin diseases such as atopic dermatitis. Known.

Recently, water softeners for converting hard water such as tap water into soft water have been introduced in order to obtain higher quality living water, and are widely used in homes and businesses.

The water softener has a principle of softening by replacing calcium ions and magnesium ions contained in hard water with sodium ions. As shown in FIG. 1, the softener 10 includes a soft water tank 11 having an ion exchange resin 1 embedded therein. And a regeneration agent 3 for regenerating the ion exchange resin 1, for example, a regeneration vessel 13 in which salt is stored therein.

The raw water is supplied to the soft water tank 11 by opening and closing the solenoid valve 14 to be softened, and then discharged through the discharge pipe 12. The flow rate of the raw water supplied to the soft water tank 11 is checked by the flow sensor 15.

After the ion exchange resin (1) is used for hard water at a predetermined flow rate, the Na component contained in the ion exchange resin (1) decreases, so that the softening capacity of the ion exchange resin (1) decreases. To be played back. When the raw water of a predetermined flow rate is detected by the flow sensor 15, the raw water is supplied to the regeneration container 13 by the control unit 16 to generate regeneration water.

That is, raw water is supplied to the regeneration container 13, and raw water dissolves the regenerant (salt) 3 so as to be regenerated water, and then regeneration water is supplied to the soft water container 11. The regenerated water supplied to the soft water tank 11 supplies Na components to the ion exchange resin 1 to regenerate the ion exchange resin 1. The water softener 10 has an advantage of accurately knowing the regeneration time of the ion exchange resin 1 by the flow sensor 15 and automatically regenerating the ion exchange resin 1 by the controller 16.

However, since the raw water supplied to the regeneration container 13 passes through the injection pipe 17 installed vertically, it dissolves the surrounding regenerant (salt) 3 to become regeneration water. Therefore, when the water pressure of the raw water changes, the concentration of regeneration water (salinity) ) Has a problem that is changed. In addition, when the height of the regenerant (salt) 3 changes, the area where the raw water and the regenerant (salt) 3 come into contact with each other causes a problem that the concentration (salinity) of the regeneration water changes. The concentration suitable for the regeneration of the ion exchange resin 1 is 8% or more and 12% or less in salinity. If the concentration (salinity) is changed, the ion exchange resin 1 cannot be effectively regenerated.

In addition, since the regenerant (salt) 3 is in the form of granules, a part of the regenerant (salt) 3 may not be injected into the regeneration vessel 13 in the process of being injected into the regeneration vessel 13 and may be scattered around. . Furthermore, the water softener 10 is generally installed at a high place, in order to inject (supplement) the regenerant (salt) 3, the user lifts the regenerant (salt) 3 up to the softener 10 installed at a high place. It is inconvenient because it must be injected into the regeneration container 13 after being raised. In addition, since the regeneration container 13 has a vertically long shape, it takes up a lot of space.

In addition, when foreign matter is contained in the regeneration agent (salt) 3, the foreign matter may be supplied to the ion exchange resin 1 together with the regeneration water. Furthermore, the regeneration container 13 is inconvenient to clean the inside because the remaining portion except the injection port is sealed.

The present invention has been made to solve the above problems, and an object thereof is to provide a regeneration water production unit having a small change in the concentration (salinity) of regeneration water.

Still another object of the present invention is to provide a regenerated water production unit that can easily replenish (inject) a regenerant.

Still another object of the present invention is to provide a regeneration water production unit which can prevent foreign matter contained in the regeneration agent from moving to the ion exchange resin.

It is still another object of the present invention to provide a recycled water production unit that is convenient for internal cleaning.

Based on the principle that can be defined, it should be interpreted as meaning and concept corresponding to the technical idea of the present invention. Therefore, the embodiments described in the present specification and the configurations shown in the drawings are merely examples of the present invention and are not intended to represent all of the technical ideas of the present invention, so that various equivalents And variations are possible.

Figure 2 is a combined perspective view showing a regeneration water production unit according to a preferred embodiment of the present invention, Figure 3 is an exploded perspective view showing the regeneration water production unit.

Referring to the drawings, the regeneration water production unit 100 includes an outer frame 20 and an inner frame 40 installed inside the outer frame 20.

The outer frame 20 is formed with a first inlet (21 in FIG. 4A) through which raw water flows and a first outlet 22 through which regenerated water is discharged.

The first inlet 21 is connected to the raw water supply pipe (81 in FIG. 8) to supply the raw water to the inlet (24). It is preferable that a check valve or a solenoid valve 82 is installed in the raw water supply pipe 81 to prevent the raw water of the inflow portion 24 from flowing backward.

The first outlet 22 is connected to the regeneration water supply pipe (84 of FIG. 8) and supplies regeneration water to the soft water tank (85 of FIG. 8). The first outlet 22 is preferably provided with two, one of the two first outlet 22 is connected to the hot water softener (85 'in Figure 9) and the other one of the first outlet 22 May be connected to the cold water softener (85).

As shown in FIGS. 4A to 4C, the outer frame 20 is preferably partitioned into the inlet part 24 and the main part 26 by the partition wall 23 provided in the vicinity of the first inlet port 21. .

The partition 23 has a through hole 23a and a spacer 23b.

The through hole 23a communicates the inlet part 24 with the main part 26. The raw water introduced into the inlet part 24 through the first inlet 21 is temporarily stored in the inlet part 24 and then moved to the main part 26 through the through hole 23a. The raw water flows toward the first outlet 22 along the bottom of the main part 26 and dissolves the regenerant 5 to become regenerated water. In the present specification, the regenerant 5 denotes a material capable of supplying a sodium component for regenerating an ion exchange resin. The regenerant 5 is one commonly used in water softeners, and the representative one is salt.

The inlet part 24 may be provided with a drain hole 25 to prevent the water level of the inlet part 24 from being excessively high. The drain hole 25 is located above the bottom of the regenerant 5. The drain hole 25 is connected to the discharge pipe (88a of FIG. 8). When the water level of the inlet portion 24 becomes equal to or higher than the drain hole 25, the raw water is discharged to the outside through the drain hole 25 and the discharge pipe (88a).

The spacer 23b is installed on the partition 23 to space between the partition 23 and the inner frame 40. Spacer 23b is to allow the raw water to smoothly flow into the inner frame 40 through the through hole (23a) by separating the partition 23 and the inner frame 40. In addition, the spacer 23b is spaced between the partition 23 and the inner frame 40 to facilitate the installation and removal of the inner frame 40.

The spacer 23b may be installed at an upper end of the partition 23, but may be installed at an intermediate portion of the partition 23 or the side 41 of the inner frame 40.

Preferably, at least two side surfaces 27a and 27b of the sides of the outer frame 20 facing each other are formed with a jaw 28 that is bent outwardly. The jaw 28 is seated with a wing 48 of the inner frame 40, which is described below.

The inner frame 40 is detachably installed inside the outer frame 20, preferably the main part 26. The regenerant 5 is stored in the inner frame 40. The lower surface of the inner frame 40 is made of a mesh (47) (47).

The second inlet 43 and the second outlet 44 are formed in the inner frame 40. The second inlet 43 is formed at the lower side of the side 41 facing the through hole 23a so that the raw water can be introduced into the inner frame 40, the second outlet 44 is the first regeneration water It is formed on the lower side of the side 42 of the first outlet 22 side to be moved to the outlet 22. The mesh 47 is installed at the second inlet 43 and the second outlet 44.

Since the second inlet 43 is formed at the side 41 of the inner frame 40, raw water may smoothly flow into the inner frame 40, and the second outlet 44 may be formed at the side of the inner frame 40. Because it is formed in 42, the regeneration water can be smoothly discharged to the main portion (26).

As the regenerant 5, a angular salt 5, preferably a angular salt 5 having a shape that conforms to the inside of the inner frame 40, for example, a rectangular parallelepiped shape, may be used. Each salt 5 is salt which is a lump of a predetermined size. As described above, the granular regenerant (salt) 3 can be scattered out of the inner frame 40 while being injected into the inner frame 40, which prevents this problem because each salt 5 is agglomerates. have. In addition, since the rectangular salt of the salt 5 is flat, it is easy to control the concentration of the regeneration water by adjusting the depth of the submerged water (regeneration water). In addition, since the salt 5 is a lump, it may be supported by the support member 45 and spaced apart from the mesh 47.

Preferably, the regenerant 5 has a height obtained by multiplying the height of the regenerant 5 required to regenerate the ion exchange resin 1 once by the desired number of regenerations. Therefore, the regeneration water of a constant concentration (salinity) can be supplied even up to the last regeneration number.

The support member 45 is installed on the upper surface of the mesh 47 at predetermined intervals. The support member 45 supports the regenerant 5 contained therein so as to be spaced apart from the mesh 47 by a predetermined interval. That is, the support member 45 supports each salt 5 but is spaced apart from the mesh 47 by a predetermined interval to form a path through which the raw water moves.

The lower surface of the mesh 47 may be provided with a support means 49 to prevent the mesh 47 from falling down.

The mesh 47 is formed of a wire in a net shape, and salt grains may not pass through. The mesh 47 is provided on the lower surface of the inner frame 40, the second inlet 43, and the second outlet 44. Even if the foreign matter is contained in the regenerant 5, the foreign matter is caught by the mesh 47 and thus cannot escape the inner frame 40. Therefore, it is possible to prevent the foreign matter from being supplied to the ion exchange resin 1.

Preferably, wing portions 48 are formed on side surfaces 41 and 42 of the inner frame 40 corresponding to the tuck 28. When the inner frame 40 is installed inside the outer frame 20, the wing 48 is seated on the jaw 28. The wing 48 serves as a handle when the inner frame 40 is installed on the outer frame 20 or when the inner frame 40 is lifted up.

When the regeneration water production unit 100 is cleaned, the inner frame 40 and the outer frame 20 are separated. The inner frame 40 and the outer frame 40 are lifted by holding the inner frame 40 by holding the wing 48. Remove the frame 20. In addition, in order to replenish the regenerant 5 in the inner frame 40, the inner frame 40 is lifted from the outer frame 20, and then the inner frame 40 is lowered to the floor to regenerate the regenerant 5 in the inner frame ( 40). At this time, the inner frame 40 may be lifted by holding the wing 48.

On the other hand, the height of the through-hole 23a, the height of the drainage hole 25, the length of the main part 26, the height of the support member 45, and the flow rate of the raw water supplied to the inlet part 24 are desired. The concentration, that is, the salinity is determined so as to obtain regeneration water of 8% or more and 12% or less.

In the regenerated water production unit 100 according to the present invention, raw water flows horizontally to dissolve each salt 5 to become regenerated water. Since the bottom surface of each salt 5 is not irregular and is horizontal, the raw water 5 is raw water. You can adjust the concentration (salinity) of the regeneration water by adjusting only the depth submerged in water. Therefore, the regeneration water production unit 100 can always regenerate the ion exchange resin 1 because the regeneration water of a constant concentration (salinity) can be produced.

Then, the operation of the regeneration water production unit 100 will be described with reference to FIG.

When regeneration of the ion exchange resin 1 is necessary, the solenoid valve 82 is opened and raw water is supplied. Opening of solenoid valve 82 may be manual or automatic.

Raw water is temporarily stored in the inlet 24 via the solenoid valve 82 and the first inlet 21, and the raw water temporarily stored in the inlet 24 is passed through the main portion 26 through the through hole 23a. Is moved to).

The raw water moved to the main part 26 flows into the inner frame 40 through the second inlet 43. The raw water introduced into the inner frame 40 flows horizontally toward the second discharge port 44 to dissolve the regenerant 5 to become regenerated water. When the water level of the inlet portion 24 is excessively high For example, when the water level of the inlet portion 24 is higher than the regeneration water of the desired concentration (salinity) can be obtained, the raw water of the inlet portion 24 is a drain hole ( It is discharged to outside through 25). That is, when the water level of the inlet part 24 is increased due to a large amount of inflow through the first inlet 21, and the water level of the inner frame 40 is excessively increased, the drain hole 25 is the raw water of the inlet part 24. By discharging the outside to adjust the water level of the inner frame 40 so that the regeneration water of the desired concentration (salinity) is made.

The regenerated water produced in the inner frame 40 is discharged to the main part 26 through the second outlet 44, and then supplied to the soft water tank 85 through the first outlet 22. The regeneration water supplied to the soft water tank 85 is discharged to the outside after regenerating the ion exchange resin (1).

On the other hand, reference numeral 86 denotes an inlet pipe for supplying raw water to the training tank 85, and 87 denotes an outlet pipe for discharging soft water from the training tank 85. In addition, 89 denotes a check valve installed in the soft water container 85 to prevent backflow, and 88 is a discharge valve that controls discharge of soft water contained in the soft water container 85.

9 shows that the regeneration water production unit 100 is installed in the water softener provided with the cold water softener 85 and the hot water softener 85 '.

The hot water softener 85 'is used to supply soft water that is hot water, and the cold softener 85 is used to supply soft water that is cold water. The same reference numerals as those in FIG. 8 among the reference numerals in FIG. 9 denote the same members having the same functions.

The regenerated water discharged from the regenerated water production unit 100 is supplied to the hot water softener 85 'and the cold water softener 85. The hot water softener 85 ′ may be connected to any one of the two first outlets 22, and the cold water softener 85 may be connected to the other first outlet 22.

As described above, the regeneration water production unit 100 does not need a separate space for storing regeneration water or raw water because raw water dissolves the regenerant 5 while flowing along the lower surface of the inner frame 40. Therefore, the regeneration water production unit 100 occupies a small space, which is advantageous in utilizing the space.

In addition, since the bottom surface of each salt 5 which is the regenerant 5 is flat and the raw water flows horizontally to dissolve the regenerant 5, the concentration of the regenerated water is controlled by controlling the height at which the regenerant 5 is submerged in the raw water. Salinity) can be adjusted to reduce the change in concentration (salinity).

In addition, since the regenerant 3 used in the general regeneration container 13 of FIG. 1 is in the form of granules, a part of the regenerant 3 is not injected into the regeneration container 13 during the injection into the regeneration container 13. It can be scattered around. In contrast, since the salt 5 can be used in the regeneration water production unit 100 of the present invention, this problem can be solved.

On the other hand, a general water softener is installed in a high place, conventionally, in order to inject the regenerant 3, the user lifts the regenerant 3 to the softener located in a high place, and then regenerates the regenerant 3 into the regeneration container 13. Injected. However, in the regeneration water production unit 100 of the present invention, the regenerant 5 is injected into the inner frame 40 after the inner frame 40 is removed and placed on the floor. This is convenient.

Furthermore, since the inner frame 40 and the outer frame 20 can be separated, the regeneration water production unit 100 of the present invention is convenient for internal cleaning.
