Description

Photocatalyst Sterilizer

The present invention relates to an apparatus for sterilizing and purifying a photocatalyst, and more particularly, when sterilizing and purifying water contaminated with bacteria and various organic substances by a photocatalytic reaction, the amount of contaminated water is increased to be evenly dispersed in the photocatalyst coating carrier. By improving the photocatalytic reactivity, it can be effectively sterilized and processed, and the restriction on installation in drinking water purification devices such as cold and hot water dispensers, cold and hot water purifiers, and direct-type water purifiers or aquariums, which require sterilization and purification treatments. It relates to a photocatalyst sterilization and purification device to improve the assemblage to facilitate the assembly and mounting more easily and without mass, and to achieve mass production.

In general, drinking water purifiers that are frequently used in homes and offices, the tap water is filtered through a plurality of water filters to filter the solids and organics in the tap water, and the purified water is supplied to the drinking water to be purified by a water direct-type water purifier or a water filter. Cold and hot water purifier to cool or heat the purified water to supply it as drinking water, and the clean and cold water collected from the deep underground, that is, the cold and hot water dispenser that supplies the bottled water to the bottled water by discharging it into its own weight and selectively cooling or heating it to supply it as drinking water. Etc.

Among these drinking water purifiers, the water direct type water purifier includes a base having a water supply inlet and a water purification outlet, a cylindrical housing coupled to the base, a water filter mounted in the housing, The filter cartridge includes a filter cartridge including a head installed above the housing. The water direct type water purifier having such a structure is configured to directly connect a water supply inlet to a water pipe or the like to purify tap water supplied from the water pipe by a water filter and to discharge the water directly through the water outlet. As time passes, a large amount of impurities accumulate on the surface, so the filtering effect cannot be expected. Therefore, new filter cartridges should be replaced regularly.

On the other hand, among the drinking water purifier, the cold and hot water dispenser and the cold and hot water purifier are provided with a reservoir that can store about 2 to 20 liters of bottled water or purified water, so that air can be introduced from outside to smoothly discharge the water stored in the reservoir. It is designed.

By the way, the cold and hot water dispenser and the cold and hot water purifier are contaminated by the purified water filter, even if the water stored in the reservoir is sanitarily purified bottled water or purified water by the purified water filter, if the purified water filter is not replaced within a predetermined period of time. In particular, even in the case of water purified by a filter or bottled water, various types of floating bacteria contained in the air are continuously introduced into the reservoir through the air inlet hole, so that the water in the reservoir is contaminated with bacteria and drinking water. There was an inadequate problem.

Accordingly, conventionally, an ultraviolet sterilizer for suppressing the generation and propagation of bacteria by ultraviolet irradiation is provided inside the water tank of the drinking water purifier.

The ultraviolet sterilizer includes a quartz tube incorporating a UV lamp, a sleeve incorporating the quartz tube, a pair of holders fixing both ends of the sleeve and supporting the embedded quartz tube, and the sleeve It is composed of a housing (Housing) having a water inlet and outlet. The ultraviolet sterilizer has the advantage that the bacteria can be sterilized by the ultraviolet rays of 254mm wavelength emitted from the UV lamp, there was the following problems.

First, since ultraviolet rays have only about 1-2 mm penetration in water, only the outer wall of the quartz tube protecting the UV lamp is sterilized, so that the entire inside of the reservoir cannot be sterilized.

Secondly, since the water sterilized by the ultraviolet sterilizer and the unsterilized water is taken out in a mixed state, there is a risk of harming the health of the drinker.

Third, since the ultraviolet sterilizer is installed in the upper part of the reservoir, when the water level in the reservoir is lowered, there is a problem that sufficient sterilization treatment cannot be exhibited.

Fourth, there was a problem that can not decompose and remove various organic substances such as environmental hormones by ultraviolet rays.

As an example to solve this problem, recently, a photocatalyst sterilization and purification apparatus capable of decomposing and removing various organic substances such as environmental hormones, as well as bacteria contained in water stored in a reservoir, for example, has been disclosed using ultraviolet light and a photocatalyst. .

The cooling coil 22 is wound around the outer circumferential wall of the water storage tank 20 so as to cool the water introduced into the reservoir 20, and the water stored in the hot water tank 30 is wound on the outer circumferential wall of the hot water tank 30. Heating means 31 is installed to heat the water, and one side of the reservoir 20 and the hot water tank 30 is provided with cold water and hot water discharge cocks 23 and 32 for discharging cold water and hot water. In addition, the inside of the reservoir 20, the hot water inlet pipe 25 is installed perpendicular to the through-hole formed in a predetermined portion of the separator plate 24 and the separator plate 24 for separating the water to be cooled and the water to be heated. It is installed. The separating plate 24 is provided to have a predetermined interval with the inner surface of the reservoir 20, the through-hole is formed in the upper surface so that the photocatalyst sterilization purification device 40 is installed toward the bottom surface of the reservoir 20. . In the figure, reference numeral 17 denotes a water level adjusting unit for adjusting the water level in the reservoir, and 21a denotes an air inlet hole.

On the other hand, the photocatalyst sterilization purification apparatus 40, as shown in Figure 2, the lower cylindrical member (smaller than the diameter of the upper cylindrical member 41a at the lower end of the upper cylindrical member 41a and the upper cylindrical member 41a ( 41b) is integrally formed, and the hollow cap Cap 41 coupled to the cover 21 of the water tank and the upper portion of the cap 41 are sealed to each other by the cap 41 and the screw 42a. Covered with a screw 42, one end is coupled to the inner peripheral surface of the cap 41 is installed vertically long, a quartz tube 44 having a UV lamp 43 therein, and the quartz tube 44 It consists of an inner side pipe | tube 45 provided in the outer side of the inside, and the outer side pipe | tube 46 provided in the outer side of the said inner side pipe | tube 45.

An opening 42b is formed in the outer tube 46 so that the power supply line 43b connected to the ballast 43a of the UV lamp 43 is exposed to the outside.

The inner tube 45 has a cup-shaped structure in which upper and lower ends have different diameters, and an upper end thereof has a diameter larger than that of the quartz tube 44 and is inserted into a lower end of the cap 41. It is fixed by the O-ring (O-Ring) 47, the lower end is connected to the discharge hole formed in the lower portion of the reservoir 20 having a diameter smaller than the diameter of the quartz tube 44. Furthermore, a plurality of water passages 45a are formed in the upper portion of the inner tube 45.

The outer tube 46 has a diameter larger than the diameter of the inner tube 45, and an upper end surface thereof is formed between the upper cylindrical member 41a and the lower cylindrical member 41b constituting the cap 41. The upper inner circumferential surface is held in close contact with the O-ring 47 while being supported by the outer circumferential surface of the lower cylindrical member 41b so as to be caught by the step portion 41c, and the lower end thereof is 10 to 50 mm from the bottom of the reservoir 20 It is located at a position spaced apart.

On the other hand, in the space between the outer circumferential surface of the quartz tube 44 and the inner circumferential surface of the inner tube 45, titanium oxide (TiO ₂ ) is formed of an inorganic material or the like so as to cause a photolysis reaction by ultraviolet rays emitted from the UV lamp 43. The photocatalyst coating carrier 48 coated on the metal material is filled.

As shown in FIG. 3, the photocatalyst coating carrier 48 may be made of stainless steel, copper, and nickel so as to increase the contact area between the photocatalyst surface area and water and increase the irradiation amount of ultraviolet rays. ), Or is formed into a spring shape 48a or a cylindrical shape 48b processed with a metal such as silver, silver, aluminum, or a silver plated metal.

In the conventional drinking water purification apparatus configured as described above, the water stored in the reservoir 20 is introduced into the space between the outer tube 46 and the inner tube 45, through the photocatalyst coating carrier 48 installed therein. I will go. At this time, as the ultraviolet light emitted from the UV lamp 43 embedded in the quartz tube 44 passes through the quartz tube 44 and is irradiated to the photocatalytic coating carrier 48, the photocatalyst coating carrier 48 is transferred. The contaminated water passes through the photocatalytic reaction, and in this process, harmful chemicals such as bacteria and environmental hormones are decomposed and sterilized. The sterilized water is passed through the cold water discharge cock 23 through the discharge hole 45b, which is the lower end of the inner pipe 45, passing through the water passage 45a formed in the upper portion of the inner pipe 45. Will be supplied to.

As such, the photocatalyst sterilizing and purifying apparatus 40 provided in the conventional drinking water purifying apparatus 40 is installed close to the bottom surface of the reservoir 20 so that the contaminated water of the reservoir 20 is irrespective of the level of the reservoir 20. It is to be introduced between the tube 45 and the outer tube 46 is to be constantly sterilized by the photolysis reaction at all times.

However, according to the structure of the conventional photocatalyst sterilization and purification device, since the inner tube 45 is formed of a glass material for light transmission, the inner tube 45 is used to drill the water hole 45a in the inner tube 45. Not only is it accompanied by difficulties, in some cases there was a fear that the inner tube 45 is damaged due to carelessness of the operator during the drilling operation. That is, since the drilling operation of the water hole 45a requires a high level of skill that requires manual work without damaging or deforming other parts at a high temperature of 500 ° C. or higher, unless a highly skilled person, such work cannot be performed. Due to this manual work, there was a problem that the cost is increased and also a considerable limitation in mass production.

Moreover, due to the above problems, it is not possible to drill a large number of water holes 45a in the inner tube 45, and only three to four water holes 45a can be drilled. When the amount of water passing through the pipe becomes insufficient, and thus the water flowing through the water passage 45a passes through the photocatalyst coating carrier filled between the quartz tube 44 and the inner tube 45. As the phenomenon of channeling occurs and the photocatalytic reactivity is greatly decreased, there is a problem in that the sterilization and purification treatment cannot be efficiently performed.

In addition, the inner tube 45 of the conventional photocatalyst sterilization and purification apparatus, in order to form the discharge hole 45b, the upper portion 45c having a large diameter must be bonded from the lower portion. Not only was it accompanied by difficulties, but it also took a lot of time.

As described above, the conventional photocatalyst sterilization and purification apparatus has a limitation in performing an efficient sterilization and purification process due to structural problems, increases manufacturing costs, and is not suitable for mass production by an automated system.

On the other hand, the aquarium has a large amount of foreign substances such as excreta and scales of fish active in the water contained therein accumulate on the bottom surface, and decomposes by microorganisms over time, depleting the dissolved oxygen of the water, The proliferation causes fish to die and cause disease.

Accordingly, in the past, as described above, a sterilization and purification apparatus using a photocatalyst or the like was provided to sterilize and purify water in the aquarium. However, the sterilization and purification device must be separately installed outside the aquarium, and for the sterilization and purification treatment, the circulation pump must be operated and forcedly circulated with a separate pipe connected between the external circulation pump and the aquarium. Not only was it accompanied by the hassle of the top, there was also a problem that the bactericidal purification effect is also poor.

Accordingly, the present invention has been made to solve the general problems of the prior art as described above, when the water contaminated with bacteria and various organic materials sterilization purification process by the photocatalytic reaction, the contaminated water is introduced to the photocatalyst coating carrier It improves the photocatalytic reactivity by dispersing it evenly, so that it can be effectively sterilized and treated, and drinking water purification equipment such as cold / hot water dispenser, cold / hot water purifier, water-type water purifier, etc. It is an object of the present invention to provide a photocatalyst sterilization and purification apparatus capable of improving assembly performance and achieving mass productivity without being restricted by installation.

The upper cap 110 is formed of Tefron (Tefron), silicone rubber, synthetic resin, stainless steel, aluminum, or the like, preferably formed of a rigid synthetic resin. The upper cap 110 has a predetermined diameter and is formed on the outer circumferential surface of the upper cylindrical member 111 and a diameter smaller than the diameter of the upper cylindrical member 111 and integrally formed at the lower end of the upper cylindrical member 111. It consists of a lower cylindrical member 112 formed as. An outer stepped portion 111a is formed between the lower end of the upper cylindrical member 111 and the upper end of the lower cylindrical member 112. In the present invention, the structure is separated from the upper cap 110 and the cover 120, the upper cap 110 and the cover 120 may be integrally injection molded.

The guide groove 113, as described later, the water flowing from the space between the inner surface of the outer tube 160 and the outer surface of the inner tube 150 to the water passage hole 114 of the inner tube 150 Act as a guide to ensure a smooth passage. At least 11 or more through-holes 114 are formed to increase the amount of inflow water introduced into the inner tube 150 so that the inflow of water is evenly dispersed in the photocatalyst coating carrier 170. As described above, in the present invention, a plurality of water passages 114 may be formed in the upper cap 110, whereby it can be evenly introduced into the photocatalyst sterilization apparatus to maximize the sterilization purification efficiency, as well as the narrowness of the reservoir. The contaminated water in the space can be sterilized in a short time.

Here, the inner tube 150, unlike the prior art, the upper and lower portions have the same diameter, the upper surface of the lower cylindrical member 112 in a state that is caught by the inner step portion (112a) of the lower cylindrical member 112. The hollow structure is supported on the inner circumferential surface of the. A groove (not shown) is formed on an inner circumferential surface of the lower cylindrical member 112, and the groove prevents water from leaking between an inner circumferential surface of the lower cylindrical member 112 and an outer circumferential surface of the inner tube 150. In addition, an O-ring 115 is fitted to tightly fix the inner tube 150 to the lower cylindrical member 112.

The outer tube 160, like the inner tube 150, has a hollow structure, so as to have a predetermined space between the inner circumferential surface and the outer circumferential surface of the inner tube 150, of the outer tube 160 While the upper surface is caught by the outer stepped portion 111a, the upper inner circumferential surface of the outer tube 160 is leak-proof O-ring 117 fitted into the groove 116 formed on the outer circumferential surface of the lower cylindrical member 112 It is fixed in close contact with the outer circumferential surface of the lower cylindrical member (112).

The inner tube 150 having such a structure is formed of glass or quartz material for light transmission, and the outer tube 160 is formed of glass, quartz, stainless steel, silver, silver plated metal, aluminum, or the like. It is. Each lower portion of the inner tube 150 and the outer tube 160 is inserted into the lower cap 180 having the following configuration is fixed tightly.

The lower cap 180 is formed of the same material as that of the upper cap 110, and includes a first flat paper surface 181a for supporting a lower surface of the inner tube 150 and the first flat paper surface 181a. A circular first coupling part 181 having a first wall surface 181b formed in the circumferential direction so as to protrude upward from the inner tube 150 so as to be closely attached to the lower outer peripheral surface of the inner tube 150; The first coupling to protrude upward from the second flat paper surface 182a and the second flat paper surface 182a to support the bottom surface of the outer tube 160 to be in close contact with the lower outer circumferential surface of the outer tube 160. It is comprised by the circular 2nd engaging part 182 which has a diameter larger than the diameter of the 1st wall surface 181b of the part 181, and has the 2nd wall surface 182b formed in the circumferential direction.

As a result, each of the lower portions of the inner tube 150 and the outer tube 160 may have a space portion of the first coupling portion 181 of the lower cap 180, and first and second coupling portions 181 and 182. The grooves may be inserted into each of the spaces and fit tightly, or grooves may be formed on the inner circumferential surfaces of the first wall surface 181b and the second wall surface 82b in the circumferential direction and may be O- It may be secured by the O-ring by inserting the ring.

A plurality of inflow holes 183 are formed in the second flat paper surface 182a of the second coupling portion 182 constituting the lower cap 180 at predetermined intervals in the circumferential direction. The inlet hole 183, when the photocatalyst sterilization and purification apparatus 100 is installed in the reservoir as described below, the lower surface is provided to have a predetermined distance from the bottom surface of the reservoir 20, so that the water stored in the reservoir It is to be introduced between the outer tube 160 and the inner tube 150.

In addition, the central portion of the first flat paper surface 181a of the first coupling portion 181 communicates with the inner tube 150 and flows into the inner tube 150 so that the sterilized and purified water is out of the reservoir 20. A discharge hole 184 is formed so as to discharge (for example, a cold water tank, a hot water tank, or a discharge cock installed below the reservoir tank). An internal thread is formed on an inner circumferential surface of the discharge hole 184. The reason why the internal thread is formed in the discharge hole 184 is to easily couple the discharge pipe protruding to the bottom surface of the water storage tank 20 (see FIG. 7) of the drinking water purifier. That is, in the related art, as shown in FIG. 1, a small diameter discharge hole 45b formed in the lower portion of the inner tube 45 is inserted into the discharge hole formed in the bottom surface of the water storage tank 20. In the lower discharge cap 180 for coupling the inner tube 150 by forming an external thread on the outer circumferential surface of the discharge pipe integrally formed in the discharge port formed on the lower surface of the reservoir 20, the discharge pipe protruding upwardly. The discharge hole 184 of the) is adopted to screw the discharge pipe. At this time, the bottom surface of the lower cap 180 has a stepped structure to be coupled to the discharge pipe at a predetermined interval with the bottom surface of the reservoir 20. That is, the bottom of the first flat paper surface 181a of the first coupling portion 181 constituting the lower cap 180 protrudes from the bottom of the second flat paper surface 182a of the second coupling portion 182. The bottom surface of the discharge hole 184 formed in the first coupling portion 181 has a stepped structure that protrudes more than the bottom surface of the first flat paper surface 181a, so that the second coupling portion 182 is formed. A predetermined gap is formed between the second flat paper surface 182a and the bottom surface of the reservoir 20. As a result, the water in the reservoir 20 flows smoothly into the space between the outer tube 160 and the inner tube 150 through the inlet hole 183 of the second coupling portion 182.

By this structure, the position fixing operation of the lower surface of the photocatalyst sterilization purification apparatus 100 can be simplified, and its assemblability can be improved.

On the other hand, the photocatalyst coating carrier 170, which is filled in the space between the outer peripheral surface of the quartz tube 140 and the inner peripheral surface of the inner tube 150, redox by ultraviolet rays emitted from the UV lamp 130 as in the prior art As a photocatalyst, titanium oxide (TiO ₂ ) is coated on an inorganic material or a metal material selected from the group consisting of spherical or cylindrical silica gel, silica alumina, and zeolite so as to cause a photocatalytic reaction by the process, as shown in FIG. 2. It is made of a spring or processed into a metal as described above, or consists of a cylindrical mesh. The photocatalyst is not limited to the above titanium oxide, but may be used by adding not more than 5% of titanium oxide to platinum, palladium, silver, nickel, and the like. As the photocatalyst material, for example, oxides such as zinc oxide (ZnO) and tin oxide (SnO ₂ ) may be used, but titanium oxide is most preferably used. The photocatalyst generates electron bands and holes by ultraviolet rays emitted from the UV lamp 130, and the holes react with water to generate hydroxy radicals having strong oxidizing power, and the electron bands are adsorbed. By giving electrons to the oxygen, it produces superoxide (O ₂ ⁻ ), which breaks down pollutants into carbon dioxide (CO ₂ ) and water (H ₂ O), or destroys coenzymes involved in the respiratory system of cells. This has the function of sterilization.

According to the photocatalyst sterilizing and purifying apparatus 100 according to the present invention having the structure as described above, the water in the lower portion stored in the reservoir 20 is the outer tube (through the plurality of inlet holes 183 formed in the lower cap 180) As it rises along the space between the inner circumferential surface of the 160 and the outer circumferential surface of the inner tube 150, it is introduced into the water passage 114 along the guide groove 113 formed in the upper cap 110 to be sterilized and purified by the photocatalyst at all times.

An upper cap 210 for coupling the upper portion of the outer tube 160, an inner tube 150 and the outer tube 160 coupled to the upper cap 110 at a predetermined distance from the outer circumferential surface of the quartz tube 140. Except for the structure of the lower cap 280 that couples the lower surface of), it has the same configuration and operation as the first embodiment described above, and the same reference numerals are designated for the same configuration as the first embodiment. Duplicate explanations are omitted.

The structure of the upper cap 210, as shown in Figure 11 and 12, has a predetermined diameter and the one side (top side as seen in Figure 11) is closed and the other side is a hollow upper cylindrical member ( 211 and a lower cylindrical member 212 having a diameter smaller than that of the upper cylindrical member 211 and integrally formed at a lower end of the upper cylindrical member 211. Between the lower end of the upper cylindrical member 211 and the upper end of the lower cylindrical member 212, when the outer tube 160 is coupled to the upper cap 210, the upper surface of the outer tube 160 is caught The outer stepped portion 211a is formed to support the.

Here, a plurality of annular protruding frames 215 and 216 are integrally formed on the outer circumferential surface of the upper cylindrical member 211. In addition, since the upper end surface of the upper cylindrical member 211 is sealed, it does not require a separate cover 120 as in the first embodiment. However, a through hole 211b is formed at the center of the upper end surface of the upper cylindrical member 211 for drawing out the wire 131 connected to the ballast 130a of the UV lamp 130 to the outside.

When the lower cylindrical member 212 is coupled to the upper cap 210 and the outer tube 160, the outer cylindrical member is in close contact with the inner circumferential surface of the outer tube 160 and on the inner circumferential surface of the quartz tube 140. It is preferable to have an inner diameter of the grade to be in close contact.

In addition, the lower cylindrical member 212 inserted into the outer tube 160 is in close contact with the inner circumferential surface of the outer tube 160 to be fixed to the outer tube 160, and the plurality of annular ( It is preferable to provide the protruding frames 217 and 218 integrally. Similarly, a plurality of annular protruding frames 219 and 220 are integrally formed on the inner circumferential surface of the lower cylindrical member 212.

The annular protruding frames 215, 216, 217, 218, 219, 220 serve as a kind of O-ring. Therefore, according to the present embodiment, as in the first embodiment, it is possible to solve the difficulty in the mold operation in which separate grooves must be formed on the outer and inner peripheral surfaces of the lower cylindrical member 112 of the upper cap 110. No cumbersome work of inserting O-rings into the grooves can greatly improve work efficiency and productivity.

In addition, the lower end surface of the lower cylindrical member 212 is provided with a plurality of guide portions 213 elongated in the vertical direction with the lower surface at predetermined intervals along the circumferential direction, each guide portion 213 On the inner side of the inner stepped portion 213a is formed.

As illustrated in FIG. 11, the plurality of guide parts 213 serve as guides so that the upper end surface of the inner pipe 150 is supported by the inner stepped part 213a so as to be supported. A water passage 214 is formed between the bottom surface of the cylindrical member 212 and the upper portion of the inner tube 150. As a result, the guide portion 213 flows in from the space between the outer surface of the inner tube 150 and the inner surface of the outer tube 160 through the inlet hole 283 of the lower cap 280 as described later. It serves to adjust the size of the water supply hole 214 to smoothly pass the water to the water supply hole 214 formed between the guide portion 213.

The upper cap 210 having such a structure is preferably formed of silicone rubber, but is not necessarily limited thereto. For example, when the upper cap 210 is formed of a material such as Tefron, silicone rubber, synthetic resin, stainless steel, or aluminum, the positions of the protrusions 215, 216, 217, 218, 219, and 220 may be used. Instead of the protrusions 215, 216, 217, 218, 219 and 220, recesses may be formed, respectively, and an O-ring may be inserted into the recesses.

On the other hand, the lower cap 280, similar to the lower cap 180 according to the first embodiment, the first flat paper surface 281a supporting the lower surface of the inner tube 150, and the first flat paper A circular first engaging portion 281 having a first wall surface 281b circumferentially projecting upward from the ground 281a to be closely attached to the lower outer circumferential surface of the inner tube 150; The first coupling to protrude upward from the second flat paper surface 282a and the second flat paper surface 282a to support the lower outer circumferential surface of the outer tube 160. A circular second engaging portion 282 having a diameter larger than the diameter of the first wall surface 281b of the portion 281 and having a second wall surface 282b formed in the circumferential direction, wherein the first coupling portion ( The bottom surface of the first flat paper surface 281a of 281 protrudes from the bottom surface of the second flat paper surface 282a of the second engaging portion 282. However, the lower cap 280 has a larger space in the first coupling portion 281 than the space between the first coupling portion 281 and the second coupling portion 282. In this case, each of the inner diameters of the first coupling portion 281 and the second coupling portion 282 has a size corresponding to the respective outer diameters of the inner tube 150 and the outer tube 160. As a result, the inner tube 150 and the outer tube 160 are fixed in a state of being in close contact with the lower cap 280. The lower cap 280 according to the present embodiment does not require separate grooves and O-rings as in the first embodiment, but may be appropriately formed as necessary.

In addition, the lower cap 280 is provided with a plurality of inflow holes 283 in the second flat paper surface 282a, as in the first embodiment, and at the center of the first flat paper surface 281a. A discharge hole 284 is formed having an internal screw thread that is screwed with the discharge pipe formed on the lower surface of the reservoir to discharge the sterilized purified water out of the reservoir 20.

The photocatalyst sterilization and purification apparatus 200 having such a structure may be installed in the drinking water purifying apparatus as described above, and in particular, as shown in FIG. 14, the storage tank 20a, the cold water tank 30a, and the hot water tank ( 30b) can be efficiently installed in a cold / hot water purifier having an independently installed structure.

The cold / hot water purifier shown in FIG. 14 is provided below the reservoir 20a for storing the water purified primarily by the purified water filter 10 and the reservoir 20a and is supplied from the reservoir 20a. Except for consisting of a cold water tank (30a) and a hot water tank (30b) for cooling and heating the purified water is the same as the structure of the cold and hot water purifier shown in FIG. When the photocatalyst sterilization and purification apparatus 200 is installed in the cold / hot water purifier, as shown in FIG. 15, the upper cap 210 is inserted into the hollow cover 290 having the external thread formed at the lower end of the outer circumferential surface. Here, the upper surface of the cover 290 is sealed by the upper cap 210, the through-hole through which the wire 131 is passed is formed in the closed upper surface.

The upper cap 210 fitted into the cover 290 as described above is tightly fixed to the inside of the cover 290 by the annular protrusions 215 and 216 formed on the outer circumferential surface thereof. In the assembled state, the photocatalyst sterilization apparatus 200 is vertically installed in the cold water tank 30a through an opening formed in the upper surface of the cold water tank 30a. At this time, the lower cap 280 of the photocatalyst sterilization and purification device is screwed with the discharge pipe protruding to the lower surface of the cold water tank 30a, as described above with respect to the first embodiment, the cover 290 Is screwed with the internal thread formed on the inner peripheral surface of the opening of the cold water tank (30a), it is assembled detachably to the cold water tank (30a).

Thus, according to the structure of this embodiment, the structure of the lower cap 280 like the said 1st embodiment not only makes the position fixing work of the lower surface of the photocatalyst sterilization purification apparatus 200 simple, but also the upper cap 210 ), It is possible to improve the assemblability of the cold water tank (30a).

(Third embodiment)

16 is a cross-sectional view of a photocatalyst sterilizing and purifying apparatus according to a third embodiment of the present invention.

In the photocatalyst sterilizing and purifying apparatus 200a according to the third embodiment of the present invention, as shown in FIG. 16, the second embodiment described above is cut except for cutting a part of the outer tube 160 ′. Since it has the same structure and operation as, the same reference numerals are given to the same configuration as in the second embodiment, and overlapping description thereof will be omitted.

Generally, drinking water purifiers are always on, but drinking water is only a few hours (eg, approximately 1-2 hours). The intensity of the ultraviolet rays emitted from the UV lamp 130 installed in the center of the photocatalyst sterilization purification apparatus 200 according to the second embodiment is water and photocatalyst coating in the space between the quartz tube 140 and the inner tube 150. It gradually weakens while passing through the carrier, and is lost while passing through the water and the outer tube 160 between the inner tube 140 and the outer tube 160, so that the amount of ultraviolet rays reaching the photocatalyst coated on the inner and outer tubes is small. Because it loses, the sterilizing power decreases toward the outside. In addition, since the water inside the photocatalyst sterilization device does not circulate with the water inside the reservoir, even if the water inside the photocatalyst sterilization device is sterilized, the water of the reservoir outside the photocatalyst sterilization device may be insignificant. . Accordingly, even if the photocatalyst sterilizing and purifying apparatus 200 according to the second embodiment is installed in the drinking water purifying apparatus, the water stored in the water storage tank of the drinking water purifying apparatus is not sterilized except for drinking water time. Therefore, in view of this point, the present invention cuts the lower end of the outer tube 160 'and couples only the upper portion of the outer tube 160' to the upper cap 210 so that the photocatalyst exposed to the cut portion is coated. The outer surface of the inner tube 150 is brought into contact with the water of the reservoir to receive ultraviolet rays irradiated in addition to drinking water time to enable sterilization by a photocatalyst and to be sterilized at all times. That is, as long as the drinking water purifier is in the ON state, the UV lamp 130 inside the quartz tube 140 is also always in the ON state, so that the water in the reservoir is lower than the inner tube 150. The photocatalyst coating is continuously sterilized by ultraviolet light emitted from the UV lamp 130.

When drinking water in this state, the sterilized water is introduced between the upper portion of the outer tube 160 'and the inner tube 150 from the cut outer tube 160' and passes through the water as described above. After sterilizing again while passing through the photocatalyst coating carrier 170 through 214, it is discharged to the discharge hole 184. Thus, according to this embodiment, since the water in a water tank can be sterilized continuously irrespective of drinking water time, the sterilization efficiency of a photocatalyst sterilization purification apparatus can be improved.

The structure of this embodiment can be suitably applied to the photocatalyst sterilization purification apparatus 100 according to the first embodiment described above.

As described above, according to the present invention, when sterilization and purification of water contaminated with bacteria and various organic substances by photocatalytic reaction, the amount of contaminated water is increased to be dispersed evenly in the photocatalyst coating carrier to improve photocatalytic reactivity. In addition, it can be effectively sterilized and purified, and drinking water purifiers such as cold and hot water dispensers, cold and hot water dispensers, water direct-type water purifiers, or aquariums that require sterilization and purification are not restricted to installation everywhere. The assembly property can be improved and mass production can be aimed at easily and easily assembling and mounting.

Although the present invention has been described with respect to the preferred embodiment, the present invention is not limited thereto, and various modifications and applications will be possible to those skilled in the art without departing from the gist of the present invention.
