Description

All-in-one shower that sprays soft water containing microbubbles

The present invention relates to an all-in-one shower that sprays soft water containing microbubbles. When showering, it absorbs hard substances and heavy metal substances in tap water and softens tap water to help moisturize and moisten the skin, and microbubbles smaller than pores It relates to an all-in-one shower that sprays soft water containing microbubbles, which not only improves cleaning power by containing it, but also can expect antibacterial and sterilizing effects by generating negative ions.

Nowadays, showers or faucets equipped with a segment filter that removes particulate pollutants (rust, foreign substances, etc.) are being used to use better quality water when showering or washing face. However, since the segment filter has pores of a certain size, there is a limit to removing ionic contaminants.

Therefore, the number of households using a water softener is increasing. A commonly used water softener uses a cation exchange resin capable of adsorbing a hard material in order to remove the hard material from tap water and provide it as soft water. For a sufficient hardness removal rate, there is a size of a cation exchange resin required for it, and there is a limit to the miniaturization of household water softeners. That is, in the case of a water softener generally used for home use, since the volume is large, there may be a limit to installing it in a narrow bathroom in a small household such as a single-person household. Furthermore, the soft water can be continuously used by replacing the cation exchange resin at regular intervals.

In order to solve the above problem, Korean Patent Application Laid-Open No. 10-2016-0057161, 'compact water softener' has been disclosed, but in a small bathroom, there may also be a limit to the installation space.

In addition, when bathing or washing face using water containing microbubbles, it is predicted that the use will increase in the future because dissolved oxygen due to microbubbles can effectively remove wastes and sebum by contacting the skin.

In general, microbubbles are generated by using ultrasonic waves or a method using a pressure reducing device such as an orifice. In these methods, separate devices such as a motor are required to artificially supply air to water for generating microbubbles, and a power source for driving the motor is also required. Therefore, since power is supplied in an environment with moisture, the user is easily exposed to the risk of electric shock, and after a certain period of time, the inside of the shower becomes full of water, so there is a disadvantage that a separate drain valve must be additionally installed.

Korea Patent Publication No. 10-2016-0057161 (published on: May 23, 2016) Korean Patent Registration No. 10-0938899 (Registration Date: 2010.01.19)

1 to 11b, the integrated shower 1 for spraying soft water containing microbubbles according to an embodiment of the present invention includes a shower head 10 having a plurality of injection holes 12; a shower body 30 having an adsorption module 32 including an ion exchange resin located therein to provide soft water from which particulate harmful substances and ionic harmful substances are removed; and microbubble generating modules 100 and 200 that are coupled between the shower body 30 and the shower head 10 and generate microbubbles, and include, microbubbles of soft water sprayed from the shower head 10 . Silver may disappear into nanobubbles and anions may be released.

In detail, the shower head 10 in which the plurality of spray holes 12 are formed can spray soft water containing microbubbles. The shower head may be provided in a cylindrical shape, and may provide an area in which microbubbles generated through the microbubble generating modules 100 and 200 can be well mixed in the soft water. In this case, the injection hole 12 may be formed in plurality on the outer peripheral surface of the cylindrical shape to enable one-way injection.

The shower body 30, in which the adsorption module 32 including the ion exchange resin is located, provides soft water from which particulate and ionic harmful substances are removed, may serve as a handle to the user or be fixed by a cradle. .

The ion exchange resin included in the adsorption module 32 may be a surface-modified cation exchange resin, for example, the surface-modified cation exchange resin may be formed by the following method.

The cation exchange resin surface modification method includes a first step of preparing an anionic polymer solution; a second step of immersing a cation exchange resin in the anionic polymer solution; and a third step of dropping an aqueous acid solution and an aqueous dialdehyde solution to the anionic polymer solution.

In the cation exchange resin surface modification method according to an embodiment of the present invention, the cation exchange resin may use a commonly used cation exchange resin. Specifically, the cation exchange resin may include one or two or more selected from polystyrene, polyacryl and divinylbenzene as a main chain, and a polymer having cation exchange property including a functional group for cation exchange on the main chain may be used. have. Preferably, the main chain of the cation exchange resin may include polystyrene and divinylbenzene together to ensure mechanical strength and durability.

Furthermore, the cation exchange resin may include a sulfonate (SO ³ - ) group as a functional group, and the effect of surface modification may be further improved by using a cation exchange resin including a sulfonate group as a cation exchanger. In addition, as the cation exchange resin, a commercially available cation resin satisfying the above conditions may be used.

In the cation exchange resin surface modification method according to an embodiment of the present invention, the anionic polymer may include one or two or more selected from polyacrylic acid, polymethacrylic acid, polystyrenesulfonic acid and polyamic acid, preferably the anion The sex polymer may be polyacrylic acid or polymethacrylic acid. By using such a polymer, there is an advantage in that the surface modification efficiency can be increased and the cation exchange effect by the surface modification can be improved. The anionic polymer solution may be preferably in an aqueous solution, and the concentration of the anionic polymer solution may be 0.1 to 1 wt%, preferably 0.2 to 0.8 wt%, and more preferably 0.25 to 0.5 wt%. When the concentration of the anionic polymer solution is too high, there is a problem in that it is difficult to achieve a uniform surface modification, and when the concentration of the anionic polymer solution is low, there is a problem in that the surface modification efficiency is lowered.

The cation exchange resin surface modification method according to an embodiment of the present invention includes a second step of immersing the cation exchange resin in the anionic polymer solution. At this time, the cation exchange resin may be immersed in 100 to 500 g, preferably 200 to 400 g per 1 L of the anionic polymer solution, and when a small amount of the cation exchange resin is immersed, the efficiency of surface modification may be excessively lowered, When a large amount of the cation exchange resin is immersed, there may be a problem that the surface modification is not sufficiently performed. In addition, the second step may further include a step of stirring for 30 minutes to 2 hours to evenly modify the surface of the cation exchange resin, and accordingly, the cation exchange resin and the anionic polymer before the treatment of the third step There is an advantage in that it can be evenly dispersed to form a uniform surface modification layer.

The method for modifying the surface of a cation exchange resin according to the present invention includes a third step of dropping an aqueous acid solution and an aqueous dialdehyde solution to the anionic polymer solution, and the crosslinking reaction occurs through the third step to wash the cation exchange resin It is possible to prevent the problem that the anionic polymer is separated from the surface even if it is carried out.

The aqueous acid solution may be preferably an aqueous solution in which an inorganic acid is dissolved, and more preferably an aqueous solution prepared by dissolving one or two or more selected from hydrochloric acid, sulfuric acid, nitric acid, phosphoric acid and perchloric acid in water. At this time, the concentration of the aqueous acid solution may be 0.3 to 1% by weight, preferably 0.4 to 0.8% by weight, more preferably 0.45 to 0.6% by weight, and when the concentration of the aqueous acid solution is low, the crosslinking efficiency may be low, and the concentration of the acid aqueous solution If is high, it may be difficult to form a uniform cross-linked layer due to the rapid cross-linking reaction.

The dialdehyde contained in the dialdehyde aqueous solution may be a compound containing aldehyde functional groups at both ends, and preferably, the dialdehyde is glutaraldehyde, succindialdehyde, and malondialdehyde. One or two or more may be selected, and more preferably, one or more selected from glutaraldehyde and succindialdehyde may be used. By using such an aldehyde, it is possible to increase the crosslinking rate and prevent the problem of unnecessarily remaining dialdehyde even after washing. The concentration of the dialdehyde aqueous solution may be 0.3 to 1.2 wt%, preferably 0.4 to 1 wt%, and more preferably 0.5 to 0.7 wt%, and if the concentration of the dialdehyde aqueous solution is low, the crosslinking rate is excessively slow. Also, if the concentration of the dialdehyde aqueous solution is high, the production cost may increase unnecessarily.

The aqueous acid solution dropped in the third step may be 50 to 100 ml, preferably 70 to 90 ml per 1 L of the anionic polymer solution, and if the amount of the acid aqueous solution is small, crosslinking may not occur, and the acid aqueous solution If the amount of dripping is large, there may be a problem that an additional washing step is required. The dialdehyde aqueous solution dropped in the third step may be 20 to 50 ml, preferably 25 to 40 ml per 1 L of the anionic polymer solution. When the amount of dialdehyde aqueous solution is small, crosslinking may not be sufficiently achieved, and when the amount of dialdehyde aqueous solution is large, the production cost may increase unnecessarily.

The cation exchange resin surface-modified by the method for surface modification of the cation exchange resin according to an embodiment of the present invention has a maximum adsorption amount of 5 times or more, specifically 5 to 7 times higher than that of the cation exchange resin before surface modification. As described above, the method for surface modification of a cation exchange resin according to the present invention can significantly improve the maximum adsorption amount of a cation exchange resin by surface-modifying a commercially available cation exchange resin in a simple way, and thus using a small amount of cation exchange resin. However, it has the advantage of exhibiting excellent adsorption power.

The cation exchange resin surface modification method according to an embodiment of the present invention may further include a washing step of washing the cation exchange resin before the first step. By including such a washing step, unnecessary components included in the cation exchange resin can be removed, and the surface modification efficiency can be further improved. The washing step may be repeated 1 to 5 times using distilled water or deionized water, and if necessary, washing may be performed using a weakly acidic solution.

The cation exchange resin surface modification method according to an embodiment of the present invention may further include a fourth step of washing after separating the cation exchange resin after the third step. By including such a washing step, it is possible to prevent the problem that unnecessary substances are mixed into the solution to be exchanged during ion exchange. In this case, the washing may be performed using distilled water or deionized water, and may be repeated 2 to 5 times.

Hereinafter, the present invention will be specifically described by way of Examples and Comparative Examples. The examples below are only for helping understanding of the present invention, and the scope of the present invention is not limited by the examples below.

[Example 1]

A commercial cation exchange resin (Amberlite IRC-108H) containing divinylbenzene and polystyrene as main chains and having a functional group of a sulfonate group is washed three times with distilled water. Polyacrylic acid was dissolved in water to prepare an aqueous polyacrylic acid solution having a concentration of 0.3 wt%, and 300 g of the washed cation exchange resin was immersed in 1 L of the prepared polyacrylic acid aqueous solution, followed by stirring for one hour. Thereafter, 0.5 mL hydrochloric acid and 0.6 mL glutaraldehyde were added dropwise to 1 L of polyacrylic acid aqueous solution to 0.5 wt % and 0.6 wt % to induce a crosslinking reaction. Thereafter, the cation exchange resin was separated and washed 5 times with distilled water to prepare a surface-modified cation exchange resin.

Evaluation of adsorption properties of surface-modified cation exchange resins

After adding 30 mL of 500 ppm methylene blue (MB) and 0.9 g of the previously prepared surface-modified ion exchange resin and untreated cation exchange resin, respectively, the mixture was stirred in a shaking incubator for 24 hours. Thereafter, the supernatant was separated and absorbance was analyzed at the maximum absorption wavelength of methylene blue to analyze the final concentration of methylene blue, and the results are shown in FIGS. 11A and 11B .

11a and 11b, the cation exchange resin without any treatment (Fig. 11a) has a maximum adsorption amount (q _max ) of 30.8 mg/g, and a cation exchange resin surface-modified according to an embodiment of the present invention ( 11b), it can be seen that the maximum adsorption amount (q _max ) is 166.9 mg/g, which shows an increase in the maximum adsorption amount of about 5.4 times by surface modification.

The microbubble generating modules 100 and 200 coupled between the shower body 30 and the shower head 10 and generating microbubbles are, as shown in FIGS. 4 to 9, cylindrical bodies 110 and 210 and, The water inlet (112, 212), the diameter of which is narrowed toward the center of the body, and the water inlet (112, 212) and the water inlet (112, 212) and the direction perpendicular to the diameter inward from the outer peripheral surface of the body is narrowed inward The air inlets 115 and 215 positioned at Mixing units 114 and 214, water moving parts 116 and 216 through which water mixed with air from the mixing units 114 and 214 pass, and the mesh filter 230 are positioned to move the water moving unit 116 , 216) may include diffusion parts 118 and 218 through which water collides with the mesh filter 230 or passes through the mesh filter. In addition, one end of the diffusion units 118 and 218 may be provided with stoppers 120 and 220 having a plurality of holes formed therein, and a mesh filter is provided at the coupling portion between the stoppers 120 and 220 and the body 110 and 210 . 230 may be interposed.

Air flows into the mixing units 114 and 214 from the air inlets 115 and 215 without a separate device due to the internal negative pressure formed by the water flowing into the water inlets 112 and 212, and the mixing units 114 and 214 ), the water particles containing air are further dispersed from the mesh filters 130 and 230, and the water containing microbubbles is supplied by moving to the water outlets 122 and 222 of the plugs 120 and 220. can be

The diameters D14 and D214 of the mixing parts 114 and 214 are smaller than the diameters D16 and D216 of the water moving parts 116 and 216, and the mixing parts 114 and 214 and the water moving part ( 116, 216) may have a diameter ratio (D14:D16 or D214:D216) of 1:3 to 1:3.5. When the ratio (D14:D16 or D214:D216) of the diameters of the mixing parts 114 and 214 and the water moving parts 116 and 216 is less than 1:3, the amount of water increased due to the water inlets 112 and 212 is less than 1:3. It may be difficult to maintain the moving speed up to the water moving parts 116 and 216 , and it may be difficult to form a negative pressure of the mixing units 114 and 214 , which induces air inflow into the air inlets 115 and 215 . In addition, when the ratio (D14:D16 or D214:D216) of the diameters of the mixing parts 114 and 214 and the water moving parts 116 and 216 exceeds 1:3.5, compared to the water moving parts 116 and 216, Since the mixing amount of air in the mixing units 114 and 214 is relatively small, the amount of microbubbles generated can be reduced, so it is preferable to have the above range. The mixing units 114 and 214 and the water moving units 116 and 216 may be provided in a cylindrical shape having a rectangular cross-section. Due to the water moving parts 116 and 216 provided in a cylindrical shape with a rectangular cross section, it provides a section in which the introduced air and water can stagnate in the water moving parts 116 and 216, so that the mixing of the introduced air and water is further improved. Well done, the time for mixing air and water in the water moving part can be increased.

4 to 6, the microbubble generating module 100 as an embodiment of the present invention effectively forms a negative pressure of the mixing unit 114 for inducing the inflow of external air from the air inlet 115, In order to optimize the effective flow of water introduced into the mixing part 114 and the formation of hydraulic pressure, the diameter D12a of the outer end of the water inlet 112 and the diameter D12b of the inner end of the water inlet 112 are) and the diameter D14 of the mixing part 114 may have a ratio of 2: (0.6 to 0.7): 1.

In addition, a cross-section of the outer end of the water inlet 112 may be cross-shaped and the cross-section of the inner end of the water inlet 112 may be circular. Since the water inlet 112 becomes narrower in diameter toward the inside of the body, the speed of water can be increased and the pressure can be lowered. Friction between water and water inlet may cause minute turbulence. Therefore, when water flows into the circular cross-section section 112b, the pressure difference with the cross-section section 112a increases, and the speed of water flowing into the mixing section 114 and toward the water moving section 116 and the mixing section 114. pressure can be created effectively. Furthermore, in order to more effectively form the speed and pressure of water flowing into the mixing unit 114 and directed toward the water moving unit 116, the water inlet 112 has a cross section section 112a and a circular section section 112b. The length ratio (L12a:L12b) may be (10.8 to 11.2):3.

In addition, the water inlet 112 further induces the formation of fine turbulence that may occur due to friction between water and the water inlet by differentiating the inclination angles of the cross-sectional section 112a and the circular cross-sectional section 112b. In 114), the water inlet 112 has an outer circumferential inclination θ1 of the cross-shaped cross-sectional section 112a so that the mixing of water and air can be made more effectively in 114). to 2.7 times the size.

The air inlet 115 corresponds to the shape and size of the water moving unit 116 and the mixing unit 114, and an amount optimized for the water introduced into the water inlet 112 and the negative pressure formed thereby. The ratio of the diameter (D15a) of the outer end, the diameter (D15b) of the inner end, and the length (L15) of the air may be (1.6~1.7):1:(6.3~6.5).

In addition, the pressure and speed of water from the water inlet 112 to the mixing unit 114 are optimized, and the water mixed with the air in the mixing unit 114 can move to the diffusion unit 118 by minimizing the loss of air. The ratio (L12:L14:L16) of the length of the water inlet part 112 to the length of the mixing part 114 and the length of the water moving part 116 is (4.4 to 4.7): 1 : (4.7 to 4.9). ) may be In this case, the pressure of the water moved from the faucet may have a pressure of 1.5 to 3.5 bar.

The diameter D16 of the water moving part 116 is smaller than the diameter D18 of the diffusion part 118, and in order to maintain microbubbles by minimizing friction between water and the diffusion part 118, the water moving part The ratio (D16:D18) of the diameter of 116 to the diffusion portion 118 may be 7:8.9 to 7:9.5.

At the center of the diffusion part 118 , a mounting groove 119 for mounting the mesh filter is located on the inner circumferential surface, and the mesh filter is located at the coupling end 123 of the stopper 120 , and the coupling end 123 is disposed in the mounting groove 119 . ) and the edge of the mesh filter, the mesh filter can be mounted at the center of the diffusion unit 118 .

The mesh filter may be provided by stacking multi-layer mesh members having a porosity of 300 to 350 mesh, for example, the stacked mesh filter may have a thickness of 0.45 to 0.55. When mesh members of less than 300 mesh are stacked, pores with relatively large or very small diameters are generated, and some microbubbles can be removed. Bubbles can be offset.

As another embodiment of the present invention, the microbubble generating module 200 is shown in FIGS. 7 to 9 , the water inlet 212 has a smaller diameter as it goes inside the body, so the speed of water increases, and thus the mixing part 214 may be lowered, and a negative pressure may be formed in the mixing unit 214 to introduce air into the air inlet 215 and the introduced air may be mixed with water. In order to optimize the effective negative pressure formation of the mixing unit 214 for inducing the inflow of external air from the air inlet 215 and the effective flow of water flowing into the mixing unit 214 and the formation of negative pressure, the water inlet 212 ), the diameter of the outer end (D212a), the inner end of the water inlet 212 (D212b), and the diameter (D214) of the mixing part are (1.4 to 1.5): (0.6 to 0.7): 1 ratio may be having

At this time, in response to the shape and size of the water inlet 212, the water moving unit 216, and the mixing unit 214, an amount optimized for the water introduced from the water inlet 212 and the negative pressure formed thereby The ratio of the diameter of the outer end to the diameter and length of the inner end of the air inlet 215 may be (2.3 to 2.4): 1: (5.2 to 5.4) so that the air can be introduced.

In addition, the pressure and speed of water from the water inlet 212 to the mixing unit 214 are optimized, and the water mixed with the air in the mixing unit 214 can move to the diffusion unit 218 by minimizing the loss of air. A ratio of the length L212 of the water inlet part to the length L214 of the mixing part and the length of the water moving part L216 may be 1:1: (3.1 to 3.2).

In another embodiment of the present invention, the plug 220 has a mesh filter 230 seated on the inner side 229 of the water outlet 222 , and may be coupled to the inner side of the diffusion unit 218 of the body. The water outlet 222 may have a circular hole 222a in the center and a plurality of fan-shaped holes 222b that are uniformly partitioned from the outer periphery thereto. Therefore, it is possible to provide water without disturbing the outflow by maintaining more dispersed microbubbles as much as possible due to the mesh filter 230 .

The mesh filter 230 may be provided by stacking multi-layer mesh members having a porosity of 300 to 350 mesh, for example, the stacked mesh filter 230 may have a thickness of 0.36 mm to 0.44 mm. When a mesh member with less than 300 mesh is stacked, pores with a relatively large or very small diameter are generated and some microbubbles can be removed. This can be offset.

The following [Table 1] shows the change of the water saving effect and the microbubble holding time when the microbubble generating module 100, 200 according to the embodiment of the present invention is mounted. At a water pressure of 0.5 to 3.1 bar, microbubbles were generated for each flow rate, and the state of the microbubbles was checked after 1 minute, and then the microbubble retention time was checked. In addition, the water saving rate before and after the microbubble generating module was installed was compared. Considering that the household water pressure is 1.5 to 3.5 bar, the holding time of the microbubbles generated for 5 seconds in the range of the water pressure is 220 to 240 seconds, that is, about 4 minutes, indicating sufficient holding time for washing or washing. gave. In addition, it can be seen that there is an effect of water saving as the water saving rate is 13 to 22%, and referring to FIG. 10, the size of the microbubbles generated by the microbubble generating module according to the embodiment of the present invention is 10 to 100㎛ It can be seen that the distribution is around 1100 μm.

The microbubble generating module 100, 200 may be coupled between the shower body 30 and the shower head 10 as an adapter by itself, and the adapter 20 into which the cylindrical body 110, 210 is inserted. ) may be provided to be coupled between the shower body 30 and the shower head 10 . For example, the fastening parts 111 and 217 may be coupled to the inner circumferential surface of the adapter 20 by taking the form of a rotating screw or a flange-like protruding form from the upper outer circumferential surface. In this case, the adapter 20 may include an adapter hole 22 on an outer peripheral surface corresponding to the air inlet hole 115 so that the air inlet holes 115 and 215 are not blocked by the adapter 20 .

The microbubbles of the soft water sprayed from the shower head 10 may disappear as nanobubbles, and negative ions may be emitted. That is, tap water passes through the adsorption module 32 containing the ion exchange resin inside the shower body 30 and becomes soft water, and the soft water passes through the microbubble generating modules 100 and 200 located inside the adapter 20 . And it can be injected from the shower head 10 through the injection hole 12 containing microbubbles. After spraying, the microbubbles become smaller and disappear as nanobubbles. The nanobubbles disappear and negative ions may be generated.

Therefore, the all-in-one shower device for spraying soft water containing microbubbles according to an embodiment of the present invention is a compact that can remove not only particulate pollutants but also ionic pollutants by providing the shower with a cation exchange resin with improved adsorption performance. It has the advantage of having a single structure. In addition, the softened tap water can be made into microbubbles through the microbubble generating modules 100 and 200, and there is an effect that anions are released along with the disappearance of the microbubbles.

Although the above has been described with reference to preferred embodiments of the present invention, those skilled in the art can variously modify and change the present invention within the scope without departing from the spirit and scope of the present invention as set forth in the claims below. You will understand that it can be done.
