The present invention relates to a water treatment apparatus configured to filter a scale contained in a liquid, and more particularly, to a water treatment having a scale filtering means having a structure capable of filtering the scale using the weight of the scale without a separate filtering net. Relates to a device.

In the present invention, the term "water treatment device" refers to a device for purifying raw water supplied such as a water purifier, a softener, and an ionizer to enable use as drinking water or domestic water.

In general, household water purifiers filter most ionic substances and microorganisms, including precipitation filters that remove fine particles and debris from tap water, sun carbon filters that adsorb and remove residual chlorine or odor-causing substances and volatile organic substances. The filter unit is composed of a combination of a reverse osmosis filter for removal or an ultrafiltration filter for removing most contaminants except ionic substances and a fucarbon filter for odor removal and water taste enhancement. The water passed through the four stages of the filter is stored in the purified water tank, and is cooled or heated through the cold water tank or the hot water tank, and then supplied to the user.

At this time, since the storage tank is difficult to be completely sealed, bacteria or microorganisms may grow through contact with the atmosphere, leading to secondary pollution of purified water, and may also cause microorganisms to proliferate in the filter itself depending on the nature of the incoming tap water. The purified microorganisms may be leaked through the purified water, and especially when the water purifier is not used for a long time, the possibility of contamination of the purified water by bacteria and microorganisms becomes higher.

In order to solve this problem, a method of coating silver (Ag) with known antibacterial properties on activated carbon used in the carbon filter, a method of supporting a ceramic antimicrobial ball containing silver in a storage tank, UV lamp sterilizer after There has been proposed a method of installing at the rear of the carbon filter.

However, the method of coating silver carbon on the fucarbon filter or using the ceramic antibacterial ball is installed in the place with high pollution, so that it is easy to introduce external impurities or neglect the internal cleaning. There is a problem that secondary pollution may occur, and the method of using an ultraviolet lamp sterilizer is relatively excellent in the instantaneous sterilization effect on the spilled purified water, but in case of serious contamination in the purified water tank, secondary pollution of the purified water can be prevented. There is no problem.

In order to solve the above problems, recently, a sterilization method through electrolysis has been devised.

Hereinafter, a conventional electrolysis type water treatment apparatus will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing the configuration of a conventional electrolysis type water treatment apparatus.

As shown in FIG. 1, the conventional electrolysis type water treatment device includes a sedimentation filter 11, a sun carbon filter 12, a reverse osmosis filtration filter 13, and a fucarbon filter 14 from a side into which raw water is introduced. Sterilization sterilized by an electrolytic cell sterilizer 20 and an electrolytic cell sterilizer 20 which sterilizes the filter unit 10 which is arranged in sequence, the purified water filtered by the filter unit 10 by electrolysis. It comprises a purified water tank 30 for storing water, a hot water tank 42 and a cold water tank 44 for heating and cooling the water supplied to the user.

Sterilization by electrolysis is a technique for sterilizing or extinguishing microorganisms remaining in water by allowing water to pass between electrodes of different polarities. The treated water includes chlorine (Cl2), hypochlorite ions (OCl-) and other sterilization ions. And oxidative mixtures with bactericidal properties such as free radicals are produced.

Various oxidants, such as hypochlorous acid, chlorine, chlorine dioxide and other chlorine-based oxidants, are the most effective bactericidal agents used for hygiene purposes in household or industrial products. The strong oxidation potential of these oxidant molecules has been applied in various fields including disinfection and sterilization, and detailed description of disinfection and sterilization processes or effects is omitted.

2 is an exploded perspective view of an electrolytic cell sterilizer applied to a conventional electrolytic water treatment apparatus, and FIG. 3 is a cross-sectional view of an electrolytic cell sterilizer applied to a conventional electrolytic water treatment apparatus.

The electrolytic cell sterilization apparatus 20 shown in FIGS. 2 and 3 is an electrolytic cell sterilization apparatus applied to a 'water treatment apparatus having an electrolytic sterilization function' previously filed by the applicant of the present invention. The positive electrode 21 and the negative electrode (22) are provided to be spaced apart at regular intervals facing each other, and the through-holes 23 are opened in both directions due to the gap (G) between the positive electrode 21 and the negative electrode 22.

The height of the through hole 23, that is, the gap G between the positive electrode 21 and the negative electrode 22 is formed at regular intervals along the length ends of the electrodes 21 and 22, preferably 0.5 mm or less, More preferably, it is provided in 0.2 mm or less. By maintaining the gap G, even water having a very low ion concentration (for example, 30 mg / l or less based on TDS concentration), such as reverse osmosis filtered purified water, can be effectively electrolyzed.

Electrode holders 24 for fixing the electrodes 21 and 22 are provided at both ends of the positive electrode 21 and the negative electrode 22, and both sides of the electrode holder 34 are provided from the respective electrodes 21 and 22.

Water flowing into the electrolytic cell sterilizer 20 is caused to undergo an electrolysis reaction by the positive electrode 21 and the negative electrode 22 while passing through the through hole 23, and bacteria contained in the water during the electrolysis reaction. Microorganisms are directly oxidized and indirectly oxidized and sterilized by various oxidative mixtures such as chlorine, ozone, OH radicals and oxygen radicals generated at the anode.

The water sterilized during the electrolytic cell sterilization device 20 is stored in the purified water tank. Since the oxidized mixture is dissolved in the water sterilized by electrolysis, the bacteria in the purified water tank due to the surrounding environment or external air, etc. Microbial generation of is suppressed secondary pollution is an advantage.

However, in the water treatment apparatus having the above structure, the scale generated when the TDS (Total Dissolved Solid) is treated as it is, such as tap water or ground water is discharged as it is, so that the flow path of the system located at the rear end is There is a drawback that various problems are caused by the scale such as clogging.

In order to prevent the discharge of the scale may be further provided with a strainer for filtering the scale, but if the strainer is provided in this way, since the configuration for the strainer coupling must be added, not only the internal configuration is complicated, but the flow rate may be reduced, When used for a long time there is a problem that the strainer may be blocked by the scale.

The present invention has been proposed to solve the above problems, it is possible to sterilize water by using an electrolysis method, it is provided with a scale filtering means consisting of a simple structure to filter the scale without a separate configuration such as a strainer It is an object to provide a water treatment apparatus.

Hereinafter, an embodiment of a water treatment apparatus having a scale filtering means according to the present invention will be described with reference to the accompanying drawings.

Figure 4 is a perspective view showing the internal configuration of a water treatment apparatus having a scale filtering means according to the present invention, Figure 5 is an arrangement and coupling structure of a positive electrode plate and a negative electrode plate applied to the water treatment apparatus having a scale filtering means according to the present invention 6 is an exploded perspective view illustrating a filtering means applied to a water treatment apparatus having a scale filtering means according to the present invention.

The water treatment apparatus according to the present invention is an apparatus for sterilizing or extinguishing microorganisms remaining in water by generating an oxidative mixture in water through electrolysis, and generating a sufficient amount of oxidizing mixture even at a low voltage by minimizing the electrode gap. It is possible to filter the scale even if scale is generated due to high TDS of water supplied.

4 to 6, the water treatment apparatus according to the present invention includes a housing 100 configured to allow fluid to flow through the inlet 110 formed at the lower side thereof and outflow through the outlet unit 120 formed at the upper side thereof. And electrolytic sterilization means 200 having an anode plate 210 and a cathode plate 220 which are alternately arranged to be spaced apart from each other at a predetermined interval, and coupled to the inside of the housing 100, and positions of the anode plate 210 and the cathode plate 220. Holder 300 for fixing the, and the through hole 412 in the vertical direction is formed so that the water passing through the electrolytic sterilization means 200 toward the water outlet 120 passes through the through hole 412 ( The support plate 410 coupled between the electrolytic sterilization means 200 and the pipe 410 provided with a hollow 422 in the vertical direction are formed to cover the upper inlet of the through hole 412. Including spout means 400 having a discharge pipe 420 coupled to the upper surface of the sphere It is.

In this case, the water treatment apparatus according to the present invention may be manufactured to further include components such as various filters or storage tanks, heating and cooling means, depending on the use. The components such as the filter, the storage tank, the heating and cooling means are applied to various kinds of water treatment apparatuses in the related art, and a detailed description thereof will be omitted.

The housing 100 shown in FIGS. 4 to 6 is configured such that the water flowing into the interior flows upward and discharges vertically, but the housing 100 applied to the present invention has a flow path of water as shown in this embodiment. It is not limited to the vertical upward as shown, but may be changed to be inclined at an angle.

Electrolytic sterilization means 200 is a device for electrolyzing water located between the positive electrode plate 210 and the negative electrode plate 220 by applying a voltage to the positive electrode plate 210 and the negative electrode plate 220, respectively, and the positive electrode plate 210 and The positive electrode plate 210 and the negative electrode plate 220 are arranged side by side along the flow direction of the water so that water flows smoothly between the negative electrode plate 220 and penetrates one wall of the housing 100 to the outside of the housing 100. The positive electrode terminal 212 and the negative electrode terminal 222 exposed to each other are formed. Therefore, there is an advantage that the wiring for applying power to the positive terminal 212 and the negative terminal 222 is simplified.

In addition, the positive electrode terminal 212 and the negative electrode terminal 222 are formed so that the vertical position is different and the housing 100 is a positive terminal hole 130 and the portion corresponding to the positive terminal 212 and the negative terminal 222 Since the negative electrode terminal hole 140 is formed, the manufacturer can assemble the positive electrode plate 210 and the negative electrode plate 220 more easily without fear of changing the coupling position of the positive electrode plate 210 and the negative electrode plate 220.

During the electrolysis reaction, the bacteria and microorganisms contained in the water are directly oxidized and indirectly oxidized by various oxidative mixtures such as chlorine, ozone, OH radicals and oxygen radicals generated in the positive electrode plate 210. Sterilization proceeds simultaneously. As described above, since the method and the effect of sterilization using electrolysis are the same as the method and effect of the above-mentioned conventional water treatment apparatus, detailed description thereof will be omitted.

In order to effectively generate an oxidative mixture, a sufficient potential difference must be provided between the positive electrode plate 210 and the negative electrode plate 220. In this case, since the oxidation may proceed to the positive electrode plate 210 itself, the positive electrode plate 210 is made of platinum or It is preferred to be coated with a platinum based material. At this time, since the platinum-based metal is very expensive, the positive electrode plate 210 may be made of a relatively inexpensive titanium plate and coated with ruthenium platinum group having a sterilizing effect.

At this time, since the oxidative mixture is generated in the positive electrode plate 210, two or more positive electrode plates 210 are provided, and the negative electrode plate 220 is provided between the positive electrode plates 210, respectively. In the present exemplary embodiment, two negative electrode plates 220 are arranged between three positive electrode plates 210 to form a total of five electrode plates. However, the number of the positive electrode plate 210 and the negative electrode plate 220 is not limited thereto and is selected by a user. Depending on the number can be applied.

In addition, the positive electrode plate 210 and the negative electrode plate 220 are arranged to have an interval of 0.5 mm or less so as to effectively generate an oxidative mixture even when a low voltage is applied, and preferably arranged to have an interval of 0.2 mm or less. At this time, the distance between the positive electrode plate 210 and the negative electrode plate 220 may be freely changed depending on the size of each of the electrode plates (210, 220), the strength of the voltage supplied, the characteristics of the water supplied.

The holder 300 is coupled to the upper and lower ends of the positive electrode plate 210 and the negative electrode plate 220 so as to fix the upper and lower ends of the positive electrode plate 210 and the negative electrode plate 220, respectively. The holder 300 has an opening 310 formed in a center portion thereof to allow water to pass therethrough, and upper ends of the positive electrode plate 210 and the negative electrode plate 220 on the surface facing the positive electrode plate 210 and the negative electrode plate 220. A slot 320 is formed in which a lower end can be inserted.

The holder 300 is the outer end is coupled to the inner wall of the housing 100, the positive electrode plate 210 and the negative electrode plate 220 is coupled so that the upper end and the lower end is inserted into the slot 320 of the holder 300 Is fixed.

In this case, the holder 300 is not limited to the rectangular shape in which the opening 310 is formed in the center portion as in the present embodiment, and the side surface may be formed in the bar shape coupled to the inner wall of the housing 100.

Filtering means 400 is a means for filtering the scale contained in the water past the electrolytic sterilization means 200, it is configured to filter the scale by using the flow pressure of the water and the weight of the scale. The supporting plate 410 and the discharge tube 420 may be integrally formed or may be combined after being separately manufactured as shown in FIG. 6.

Since the outer end of the support plate 410 is in close contact with the entire inner wall of the housing 100, the water and the scale flowing through the electrolytic sterilization means 200 to the water outlet 120 will pass through the discharge pipe 420. . At this time, since the inner horizontal area of the discharge pipe 420, that is, the cross-sectional area of the hollow 422 is smaller than the horizontal cross-sectional area of the inside of the housing 100, the water is increased in speed while passing through the discharge pipe 420, the discharge pipe ( As soon as it exits 420, the speed is drastically reduced. Since the scale has a specific gravity higher than that of water, the scale does not reach the water outlet 120 after being discharged from the discharge pipe 420 and is accumulated on the upper surface of the support plate 410. As such, if the scale leakage to the outside of the housing 100 is prevented, there is an advantage that the system located at the rear end of the housing 100 is not blocked or damaged by the scale.

In order to prevent the scale from leaking out of the housing 100, instead of installing the filtering means 400, a method of installing the filtering net in the water outlet 120 may be proposed, but when the filtering net is installed in the water outlet 120. Scale is re-introduced between the positive electrode plate 210 and the negative electrode plate 220 may not only hinder the efficiency of the electrolysis, but also has a disadvantage in that maintenance and repair is cumbersome since the filter net needs to be cleaned and replaced periodically.

On the contrary, the filtering means 400 applied to the present invention may not only have a simple configuration but also prevent a phenomenon in which the scale is re-introduced between the positive electrode plate 210 and the negative electrode plate 220 and the phenomenon of leaking out of the housing 100 at the same time. There is an advantage.

A detailed description of the process in which the scale is discharged from the discharge pipe 420 and loaded on the upper surface of the support plate 410 will be described in detail with reference to FIG. 7.

7 is a cross-sectional view of a water treatment apparatus including a scale filtering means according to the present invention.

As shown in FIG. 7, water introduced into the housing 100 through the inlet 110 is sterilized while passing between the positive electrode plate 210 and the negative electrode plate 220, and is disposed as a filtering means 400 positioned at an upper side thereof. Will move.

When the water passing through the electrolytic sterilization means 200 and the scale S are introduced into the hollow 422 of the discharge pipe 420, the position head increases, but as the speed increases, the pressure head decreases as mentioned above. , Water and scale (S) is sucked into the discharge pipe (420). Water and scale (S) introduced into the discharge pipe 420 is reduced both in the position head and the pressure head at the moment of exiting the discharge pipe 420, so that the speed is sharply reduced, the force going upwards is sharply reduced .

At this time, the scale (S) has a specific gravity, that is, the mass per unit volume is greater than the water, so that the upward speed is further reduced by its own weight, so that the scale (S) does not reach the water outlet 120 and falls down. Since the water and the scale S are continuously ejected to the discharge tube 420, the scale S falling downward is not loaded into the discharge tube 420 and is loaded on the upper surface of the support plate 410.

When the discharge tube 420 and the water extraction unit 120 are formed too close, the scale S exiting the discharge tube 420 may be introduced into the water extraction unit 120 without a time margin to decrease the speed. The separation distance D between the discharge tube 420 and the water outlet 120 is preferably at least 5 mm.

In addition, the scale (S) mounted on the upper surface of the support plate 410 can move a certain distance due to the vortex of water, but when the operation is stopped because the upper end of the discharge pipe 420 is higher than the support plate 410, that is, the discharge pipe Even if there is no flow rate passing through 420, the scale S does not flow into the discharge pipe 420. At this time, if the height H of the discharge pipe 420 is too low, the scale S may reflow into the discharge pipe 420 when a variable such as the water treatment device is inclined, so that the discharge pipe 420 ) Is preferably formed to have a height H of 5 mm or more.

In addition, the filtering means 400 applied to the present invention, when there is no fear that the scale (S) loaded on the upper surface of the support plate 410 is re-introduced into the electrolytic sterilization means 200, the support plate 410 without the discharge pipe 420 It may consist of only).

8 is a sectional view of a second embodiment of the filtering means applied to the water treatment apparatus including the scale filtering means according to the present invention.

When the lower end of the hollow 422 of the discharge pipe 420, that is, the inlet side of the hollow 422 is formed at right angles, the flow path narrows rapidly, and water flowing into the filtering means 400 collides with the bottom of the support plate 410. Vortex occurs, and thus water and scale S passing through the electrolytic sterilization means 200 do not normally flow into the discharge pipe 420. In addition, if a step is formed between the through hole 412 of the support plate 410 and the hollow 422 of the discharge pipe 420, the water is an obstacle to passing through the filtering means 400, the through hole 412 Sidewalls of the and hollow 422 is connected to form one surface as shown in Figure 8 is preferably formed in a shape that widens toward the lower side.

In addition, the lower inlet of the through hole 412 is more preferably formed in a curved surface along the streamline of water flowing into the filtering means (400).

As mentioned above, although this invention was demonstrated in detail using the preferable embodiment, the scope of the present invention is not limited to a specific embodiment, Comprising: It should be interpreted by the attached Claim. In addition, those skilled in the art should understand that many modifications and variations are possible without departing from the scope of the present invention.

The water treatment apparatus according to the present invention can sterilize water using an electrolysis method, and can be scaled with a simpler structure without a separate configuration such as a strainer to prevent product damage, and the scale is electrolytic sterilization. There is an advantage that can prevent the phenomenon that the electrolysis effect is inhibited by preventing the phenomenon flowing back into the means.

In addition, the water treatment apparatus according to the present invention can increase the production efficiency of the oxidative mixture by arranging more positive plates than the negative plates, and since the positive and negative terminals are exposed on one side of the housing, the wiring becomes simple, and the positive and negative terminals There is an advantage that the assembling becomes easy.
