Description

Water softener

The present invention relates to a softener, and more particularly, to a softener configured to disassemble and assemble the softener so that activated carbon or refined salt can be added if necessary.

There are many kinds of water on Earth, and they are classified according to various classification criteria. Such water includes natural water and processed water that has been processed to change the natural water.

Several kinds of natural water include soft water in rivers, lakes, or reservoirs, and hard water in which limestone is dissolved, such as carbonate or magnesium sulphate. In other words, limestone-rich water contains a large amount of calcium (Ca) and magnesium (Mg), which is hard water, and soaps are not washed well. In contrast, calcium and other dissolved water Water that is low in constituents is called soft water.

Various softening devices are used to change the hard water to soft water, but the conventional softener is difficult to disassemble and assemble, and thus, the internal cleaning of the softener is very inconvenient to maintain. In addition, the filter screen installed inside the water softener is separated or damaged from the installation port, which lowers the filtering function, thereby lowering the reliability of the product, and furthermore, there is a risk that the ion resin inside may flow out. In addition, the filter screen or the cation resin cover is welded or fully grounded rather than assembled, so it is almost impossible to exchange the cation resin. In addition, the conventional water softener has a problem that a large amount of installation area is required because the internal flow path is complicated, compared to the processing capacity.

The present invention has been made to solve the above problems, and easy to assemble and disassemble, as well as very easy to clean and maintain, the filter screen to be installed inside to support the filter screen with a separate cover does not cause any filter damage filtering efficiency It has a high volume and its volume is small compared to the processing capacity, and it occupies a narrow installation area.In particular, the activated carbon and magnet can be inserted into the upper and lower spaces to simultaneously purify and magnetize the water. The purpose is to provide a water softener configured to sterilize and wash cationic resin while circulating.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

1 is an exploded perspective view schematically illustrating the configuration of a water softener according to an embodiment of the present invention.

As shown, the water softener according to the present embodiment, a case 11 including a cationic resin (33 in FIG. 2), and an upper cover 13 and a lower cover 27 to seal the case 11 from the top and bottom. And a support member 49 fixed to the outer wall (not shown) to support the case 11.

The case 11 is a cylindrical member having an empty inside, and female threads are formed on the upper and lower inner circumferential surfaces thereof, and two fixing members 39 are fixed up and down on one outer circumferential surface thereof. The fixing member 39 has a shape of a bolt and has a thread 69 formed therein, and a head 45 is formed at one end thereof. The nut 41 is already screwed on the thread 69, and a washer 43 is interposed between the nut 41 and the head 45. As described above, the front end surface 67 of the fixing member 39 is fixedly coupled to the outer circumferential surface of the case 11 while the washer 43 and the nut 41 are fitted.

On the other hand, a separate support member 49 is provided to vertically install the case 11, the support member 49 is formed with a plurality of fasteners (59) to be fixed to the required position of the wall, For example, it is fixed to the wall by suitable fixing means such as screws. In addition, the support member 49 is formed with two support members 47 to accommodate therein the fixing member 39 provided on the outer circumferential surface of the case 11 to mount the water softener. The support 47 takes the shape of a keyhole, and supports the head 45 through the support 47. That is, when the head 45 having a round cross-sectional shape passes through the round through part 71 and is lowered and positioned at the support part 73, the nut 41 side facing surface of the head part 45 is located. It is supported and mounted on the back surface of the support tool 47 corresponding to this support part 73. Naturally, the width of the support portion 73 should be larger than the thickness of the threaded portion of the fixing member 39.

Therefore, when the head 45 of the fixing member 39 is tightened to the head 45 side with the nut 41 mounted on the rear surface of the support 47, the supporting member 49 is the head member 45. It is tightly fitted between the washer 43 and the mounting is completed. Of course, the separation distance between each support 47 is the same as the separation distance between the fixing member 39, of course.

When separating the water softener from the support member 49, loosen the nut 41 from the head portion 45, loosen the nut 41 from the head portion 45, and pull the water softener to the upper state, thereby supporting the support 47. The head 45 may be removed from In addition, of course, the number of fixing members may be increased to correspond to the size of the water softener.

The upper cover 13, which is installed by screwing on the upper end of the case 11, provides a space portion 15 having a hemispherical shape, and a male screw is formed at the lower end thereof to be coupled to the upper end of the case 11. In addition, the space 15 may take the form of a hemisphere and may include activated carbon 63 or refined salt 65 described later. Inlet portion 19 is provided in the upper portion of the upper cover (13). The inlet 19 is a hole formed through the upper cover 13 and an internal thread is formed on the inner circumferential surface thereof, thereby closing the cap 17. As the upper cover 13 and the cap 17 are screwed together, sealing and separation are possible, so that if necessary, the tablet salt 65 may be introduced through the inlet 19 by opening the cap 17.

On the other hand, the support jaw 57 is formed on the inner circumferential surface of the upper cover 13. The magnet 29 is supported on the support jaw 57. The magnet 29 is shaped like a ring, and the edge portion of the magnet 29 does not move into the space 15 due to the supporting jaw 57.

Four screw holes (not shown) are formed in the lower surface of the upper cover 13. The screw hole has the same shape as the screw hole 51 provided on the upper surface of the lower cover 27 and is combined with the fixing screw (53 in Fig. 2) to the filter cover 35 and the screen member 37 to be described later It is fixed in close contact with the upper cover (13). Since the filter cover 35 and the screen member 37 are supported by the fixing screw (53 in FIG. 2) toward the upper cover 13 side, the magnet 29 supported by the support jaw 57 is a space 15. Stable within In addition, as will be described later, the magnet filters the material such as iron contained in the water and serves to magnetize the water.

The lower cover 27 is coupled to the lower end of the case 11. Like the upper cover 13, the lower cover 27 is screwed with the case 11 to seal the case and can be assembled and disassembled. A screw hole 51 is formed in the upper surface of the lower cover 27, and the screw hole 51 is a hole provided to fix the filter cover 35 and the screen member 37 to the lower cover 27. Fixing screw (53 in Fig. 2) is combined. In addition, as in the upper cover 13, the space 21 is formed inside the lower cover 27, and the support jaw 57 is provided on the inner circumferential surface of the space 21 to support the magnet 29.

On the other hand, the inlet 23 is provided in the lower center of the lower cover 27, the outlet 25 is located on the side of the inlet (23). The inlet 23 is formed in the longitudinal direction of the case 11 and is an installation hole through which the flow pipe 31 passes. Therefore, as shown in FIG. 2, the hard water flowing in the direction of arrow i through the flow pipe 31 installed in the inlet 23 is changed to soft water through the flow path inside the case, and the direction of arrow o through the outlet 25. Outflow. A separate external pipe is connected to the lower end of the flow pipe 31 on the inlet 23 so as to supply hard water to be treated, and a water supply control mechanism such as a cock is installed on the outlet 25 side. .

The two filter covers 35 and the screen member 37 fixedly coupled to the lower surface of the upper cover 13 and the upper surface of the lower cover 27 serve as a disk-shaped member to filter impurities in the working fluid. The magnet 29 is supported so as to be located in the spaces 15 and 21 of the upper and lower covers 13 and 27, respectively.

The filter cover 35 is a disc-shaped member, which is the same as the diameter of the upper and lower covers 13 and 27, and the edge of the edge is in contact with the inner circumferential surface of the case 11, and the through hole 61 through which the fixing screw 53 penetrates the edge. Is formed. In addition, a pipe through hole 77 is formed in the center portion. The pipe through hole 77 is a hole formed so that the flow pipe 31 penetrates and is installed in the case 11 in the longitudinal direction, and is in contact with the outer peripheral surface of the flow pipe 31. A flow port 75 is provided around the pipe through hole 77. The flow port 75 is a passage provided for flowing the working fluid, and the larger the area is, of course, the better unless the mechanical strength of the filter cover 35 is reduced. The filter cover 35 is superimposed in a pair of two sheets, the screen member 37 is interposed therebetween.

The screen member 37 is sandwiched between the filter covers 35 as a mesh-type filter and supported to filter impurities in the flowing water. A pipe through hole 77 is formed in the central portion of the screen member 37, and a through hole 61 is formed in the edge portion to penetrate the fixing screw 53. In this embodiment, one screen member 37 is used, but of course, multiple screen members 37 may be used according to the embodiment. In addition, in the case of using a plurality of screen members 37, the filter cover 35 having a predetermined thickness is interposed between the screen members 37, and corresponds to the thickness of the filter cover 35 between the screen members 37. A gap may be provided. In addition, the screen member 37 may be applied to various filters other than the mesh type.

The flow pipe 31 is a flow passage through which the hard water passes, and serves to move the hard water to the space part 15 of the upper cover 13. The flow pipe 31 penetrates through the inlet 23 of the lower cover 27 and the pipe through hole 77 so that its upper end reaches the space 15 of the upper cover 13. The lower end of the flow pipe 31 is connected to an external pipeline (not shown) to receive hard water to be processed.

The cation resin 33 is also supplied to the inside of the case 11 to absorb impurities such as carbonate, sulfate, and magnesium salt in hard water.

2 is a view schematically showing the operation of the water softener according to an embodiment of the present invention.

The same reference numerals as the above reference numerals denote the same members having the same function.

As shown, the cationic resin 33 is filled in the case 11. The cationic resin 33 is present in the form of granules and absorbs various impurities including carbonate, sulfate, and magnesium salts from hard water flowing in contact with the outer surface. As cationic resins absorb impurities in hard water, hard water is converted to soft water and treated with water. However, since the cationic resin 33 continuously adsorbs the impurities when the water softener is used, the absorption capacity decreases with time, and the efficiency of the device is reduced. Therefore, it is necessary to periodically clean and disinfect the cationic resin, which will be mentioned by the description of FIG. 4 to be described later, but it is possible to clean and disinfect the cationic resin without separating the apparatus using a purified salt.

The operation of the water softener is explained as follows.

First, when the hard water flows in the flow pipe 31 from the outside in the direction of the arrow i, the hard water flows upward in the flow pipe 31 and blows out in the direction of the arrow a to the space 15 in the upper cover 13. do. Since the space part 15 is sealed by the cap 17, the leakage of hard water does not occur to the outside. As described above, since the magnet 29 is inserted and positioned in the space 15, the hard water ejected in the direction of the arrow a is first magnetized by the magnet to become magnetized water. It is known that magnetized water is good for the body. The hard water magnetized by the magnet 29 flows in the direction of the arrow b and moves into the case 11. At this time, the hard water flows through the flow port 75 and the screen member 37 of the filter cover 35 and impurities are filtered out.

The hard water flowing into the case 11 flows between the cationic resins 33 in the direction of the arrow c. Since the cationic resin 33 is a fine granular form, the hard water moving downward through the gap between the particles of the cationic resin 33 is sufficiently in contact with the cationic resin 33 and dissolved with magnesium salts, sulfates, and carbonates. The same impurity is transferred to the cationic resin 33 and is changed to soft water. As described above, the hard water / soft water movement in the direction of the arrow c is naturally made by gravity, if you want to move faster, you can adjust the water supply pressure of the hard water flowing in the direction of the arrow i. The hard water flows into the soft water while flowing in the direction of the arrow c, moves into the space 21 in the lower case 27, and is supplied to the required place through the outlet 25.

3 is a view showing a state in which the water purifier is added to the water softener according to an embodiment of the present invention.

In addition, the same reference numerals as the above reference indicates the same members having the same function.

As shown in the figure, activated carbon 63 is applied to the spaces 15 and 21 provided in the upper cover 13 and the lower cover 27. As is known, activated carbon is selected from vegetable raw materials such as sawdust and coconut shell or pine bark and made into charcoal at 400-700 degrees, and treated with high temperature (900-1200 degrees) and steam treatment called resurrection. It is a colorless, odorless black powder or granular material with excellent adsorption performance. It is insoluble in acid and alkali organic solvents and has excellent deodorizing and decolorizing adsorption ability. By placing the activated carbon 63 in the flow path through which the water of the upper and lower parts of the case 11 passes, the water purification effect of the water is passed through the water softener of the present invention. For example, a water softener can be used for multipurpose purposes.

4A and 4B are schematic cross-sectional views schematically illustrating the principle of disinfecting and washing a cationic resin provided in a softener according to an embodiment of the present invention.

As described above, the cationic resin 33 continuously absorbs a substance such as carbonate, sulfate, or magnesium salt contained in the hard water during operation, and thus has a low capacity for absorbing it for a long time, resulting in very high soft water treatment efficiency. Will fall. Therefore, the cationic resin should be replaced or sterilized / washed regularly. According to such a demand, the water softener of the present invention can simply put the purified salt 65 into the space portion 15 in the upper cover 13 to sterilize and wash the cationic resin 33, thereby making it possible to use expensive cationic resin. It can be recycled to prevent waste of resources.

That is, referring to FIG. 4A, the cap 17 provided on the upper portion of the upper cover 13 is removed from the inlet 19, and the refined salt is introduced in the direction of the arrow m through the inlet 19. The space 15 is blocked by the magnet 29, the filter cover 35, and the screen member 37 so that the tablet salt 65 may be supplied and stay in the space 15. After the refined salt 65 is supplied into the space 15 as described above, as shown in FIG. 4B, after closing the inlet 19 with the cap 17 to seal the space 15, the water is pressurized. To eject in the direction of arrow a. At this time, the supplied water does not use hard water and general tap water may be used. The water ejected in the space 15 dissolves the purified salt, turns into brine, flows downward, and passes between the cation resins 33. The brine is washed while removing the foreign matter adsorbed on the cation resin while passing between the cation resin (33). Continued supply of water from the outside gradually reduces the amount of refined salt. If the contamination of the cationic resin 33 is very severe, the above operation may be repeatedly performed to completely clean and sterilize the cationic resin.

The present invention has been described in detail through specific embodiments, but the present invention is not limited to the above embodiments, and various modifications may be made by those skilled in the art within the scope of the technical idea of the present invention. .

The water softener according to the present invention made as described above can be assembled and disassembled to facilitate cleaning and maintenance of the water softener, and the filter screen installed therein is supported by a dedicated cover so that the filter is not damaged and thus the filtering efficiency is improved. Good and reliable. In addition, the installation area occupies a narrow range compared to the processing capacity, and activated carbon and magnets can be applied to the upper and lower spaces to simultaneously purify water and magnetize water. In particular, it is configured to sterilize and clean the cationic resin simply by circulating the water by putting the purified salt in the upper space, there is an effect that can clean and sterilize the cationic resin without decomposing the water softener.
