[0002]

2. Description of the Related Art To remove undesired substances such as odor and residual chlorine from water to be treated such as tap water and to add a predetermined mineral to obtain so-called delicious water close to natural water.
High performance cartridge water purifiers are known.

This type of cartridge type water purifier usually has a structure in which various filter materials, for example, non-woven cloth, activated carbon, etc., ceramics and other predetermined water-permeable materials are stacked in a single cartridge and stored in a plurality of layers. Have. For this reason, if the purification treatment capacity of even one type of water treatment material is reduced in the cartridge, the entire cartridge must be replaced with a new one, and another type of passage treatment that still has the purification treatment ability still remains. The water treatment material was also replaced, resulting in waste of the water treatment material, which was uneconomical.

On the other hand, in order to secure a sufficient amount of treated water while increasing the treating capacity of various cartridges used in a water purifier, the following method is generally considered. (1) Extend the distance that water passes through the water treatment material. (2) Allow water to pass slowly over time. (3) Use a special water treatment material that utilizes a certain chemical reaction.

However, in the case of the above (1), it is necessary to increase the thickness of the water-permeable material, and therefore, the length of the cartridge must be relatively long (or the diameter of the cartridge must be relatively large). In addition, there is a problem that a compact size water purifier cannot be obtained. In the case of the above (2), since water is allowed to pass slowly,
The amount of water was low and it was not suitable for use in daily life. Furthermore, in the case of the above (3), although the size of the water purifier can be made compact, a large amount of treatment cannot be performed due to the use of the chemical reaction of the water passing treatment material, and the treatment limit is reached in a relatively short time. And the cartridge had to be replaced early, which was uneconomical.

[0006]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to solve the above-mentioned problems, to make it possible to use various water-permeable treatment materials until their life, to be compact, to have excellent handleability, and to reduce the amount of treated water. An object of the present invention is to provide a cartridge type water purifier that can secure a large amount. Another object of the present invention is to provide a cartridge for a water purifier capable of further increasing the processing capacity thereof while keeping the size of the cartridge compact according to the purpose of the water passage treatment of each cartridge. .

[0007]

In order to achieve the above object, the present invention employs the following means. That is,
The invention according to claim 1 comprises at least three cartridges, each having a different main purpose of water passage processing, and a gantry for supporting each of the cartridges independently and detachably, the gantry corresponding to the cartridge. A number of receiving portions are independently formed, and the receiving portions are connected in series by a water flow means, and an end of one cartridge is fitted to each of the receiving portions in a watertight state. It is a water purifier.

According to the first aspect of the present invention, since at least three cartridges are used for each main purpose of the water-passage treatment, different water-passage treatment materials are separated and stored in the cartridges for each main purpose. Can be. For this reason, various water treatment materials can be used up to their life, and the size of the cartridge can be reduced. In addition, a number of receiving portions corresponding to the cartridges are independently formed on the gantry, and the receiving portions are connected in series by a water-passing means, and the end of one cartridge is fitted to each of the receiving portions in a watertight state. Because of the configuration, the handleability such as cartridge replacement is excellent, and a large amount of treated water can be secured.

According to a second aspect of the present invention, in the first aspect of the present invention, each of the cartridges has two concentric sleeves formed at an end of a cylindrical cartridge to be fitted to the receiving portion. A central part and a peripheral part of the two sleeves are formed as a water outlet and a water inlet, respectively. On the other hand, the receiving part is formed with a concentric socket part which fits in a watertight manner with the two sleeves. By rotating the cartridge clockwise or counterclockwise about the axis while the cartridge is inserted in the receiving portion, a plurality of claws provided at predetermined intervals in the circumferential direction near the end portion of the cartridge are provided. A water purifier characterized in that the water purifier is fitted to or released from a plurality of claw receiving portions provided on an upper surface of a gantry near the receiving portion corresponding to the plurality of claws.

According to the second aspect of the present invention, in the first aspect of the present invention, each of the cartridges and the receiving portion formed on the pedestal have the above-described structure. Can be easily and reliably exchanged, and handling is easy.

According to a third aspect of the present invention, in the first or second aspect of the present invention, the cartridge mainly includes a first cartridge mainly for removing at least residual chlorine and a cartridge mainly for removing unnecessary substances by ion adsorption. Including a second cartridge intended for use and a third cartridge mainly intended for providing at least a mineral component, water is supplied in the order of the first cartridge, the second cartridge, and the third cartridge. It is a water purifier.

According to the third aspect of the present invention, in the first or second aspect of the present invention, the so-called delicious water close to natural water is ensured by sequentially passing the first to third specific cartridges. Can be obtained. Preferably, the first cartridge contains activated carbon and / or sulfite, the second cartridge contains a ceramic material, and the third cartridge contains quartz diorite. It can be configured.

According to a fourth aspect of the present invention, in the cartridge for a water purifier, a plurality of sections accommodating the water treatment material are formed in the cartridge in the axial direction of the cartridge to form a multilayer structure, and the axis of the cartridge in each section is formed. A cartridge for a water purifier, characterized in that the water flows in the plurality of sections in order so that the directions of the water currents intersecting with each other alternate through the plurality of sections.

According to the fourth aspect of the present invention, it is possible to lengthen the distance that water passes through the water treatment material. Therefore, in the cartridge adopting the multilayer structure of the water passage treatment material, the target processing capacity can be further increased while keeping the size of the cartridge compact.

[0015] In the fourth aspect of the present invention, preferably, a plurality of partition plates having through holes for allowing water to pass through the eccentric position are provided at predetermined intervals in the cartridge as in the fifth aspect of the invention. To form the plurality of partitions, and adjust the orientation of the plurality of partition plates so that the positions of the through holes are staggered with respect to the axis of the cartridge.

According to a sixth aspect of the present invention, in the cartridge for a water purifier, a plurality of sections accommodating a water treatment material are formed in the cartridge in the axial direction of the cartridge to form a multi-layer structure. A water-permeable treatment material having a small particle size is filled, and a water-permeable treatment material having a large particle size is movably accommodated in a section located below the section, and the lower layer is traversed through the plurality of sections. A water purifier cartridge characterized in that water is sequentially passed from the upper layer to the upper layer.

According to the sixth aspect of the present invention, when water is passed through a certain kind of water passing treatment material (for example, ceramic),
Friction and / or collision of the water-permeable treatment materials having a large particle size in the lower layer section amplify the processing capacity of the water-permeable treatment material, and thereafter, the small particle-size passage filled in the upper layer section. By allowing the water to pass through the water treatment material, the water can be reliably brought into contact with the water treatment material. Therefore, by the synergistic effect of the lower layer and the upper layer, the processing capacity can be remarkably increased while keeping the size of the cartridge compact.

Forming a section in which at least three water-permeable materials are stored, storing the water-permeable material in a section located in the middle layer so as to be freely movable in the section, and forming a section located in the middle layer The particle size of the water treatment agent in the inside is made larger than the particle size of the water treatment agent in the section located in the upper layer, and smaller than the particle size of the water treatment agent in the section located in the lower layer Thus, a cartridge for a water purifier can be obtained. Thereby, the synergistic effect can be further enhanced.

In the above-mentioned invention, it is preferable that the water-permeable material is a ball-shaped and / or granular ceramic. Ceramics synergistically perform physicochemical and biochemical purification actions such as adsorption and removal of suspended matter contained in water and adsorption and decomposition of water-soluble substances by an ionic effect. This is because when friction and collision between the members occur without interruption, they can be amplified.

According to the invention of claim 8, in the water purifier cartridge, a section in which the water-passage treatment material is stored in the cartridge and a passage for guiding water passing through the water-passage treatment material to an outlet are formed. And a pair of dissimilar metal materials having different ionization energies arranged in a non-contact state.

According to the eighth aspect of the present invention, when water passes through a passage in which a pair of dissimilar metal materials having different ionization energies are arranged in a non-contact state, the ionization energy generated between the dissimilar metal materials is utilized. By increasing the antibacterial effect by ionizing water, it is possible to contribute to the enhancement of the processing capability while keeping the size of the cartridge compact.

Preferably, the invention of claim 8 is provided with a convex lens for converging light from the outside of the cartridge to at least a part of the pair of dissimilar metal materials as in the invention of claim 9. The ionization energy can be amplified by converging the light beam outside the cartridge and capturing a small amount of infrared light into the cartridge and applying heat energy to the pair of dissimilar metal materials. Here, preferably, the pair of dissimilar metal materials comprises a combination of a gold bar or at least a metal bar with a gold plating on the surface and a silver bar or a metal bar with a silver plating on the surface.

According to a tenth aspect of the present invention, there is provided an ionizer for a water purifier, comprising: a pair of dissimilar metal materials having different ionization energies arranged in a non-contact state; and a convex lens for converging light to at least a part of the pair of dissimilar metal materials. It is.

According to the tenth aspect of the present invention, the antibacterial effect can be enhanced by amplifying ionization energy and ionizing water according to the same principle as that of the ninth aspect.

In the water purifier of the present invention, at least three cartridges having different main purposes of the water flow treatment are required. One reason for using at least three cartridges is, for example, to make the process consisting of purification → ionization → mineralization for realizing so-called delicious water with a water purifier closer to the natural water purification system. This is because it was thought that it would be better to provide three cartridges independently to make it difficult for water after one process to mix with water in the previous stage at all times. By adding a combination of at least three cartridges from a variety of cartridges with different main purposes for water-flow treatment and incorporating them into a water purifier, added value other than pure water purification is provided. This is because we thought that a water purifier could be realized. Here, a cartridge having a different main purpose of the water flow treatment is defined as a main physical action or physicochemical and / or physicochemical effect received by passing water through one cartridge.
Or, cartridges having different biochemical actions from each other.

FIGS. 3A and 3B are explanatory views showing an example in which the cartridge 3 can be attached to and detached from the gantry 2. FIG. 3A is a plan view of the cartridge, and FIG. 3B is a portion showing the structure of the receiving portion 4 and its vicinity. It is a top view. The cartridge 3 is provided with a plurality of claws 3 provided at predetermined intervals in the circumferential direction near its end.
1 and 32 are provided. On the other hand, the gantry 2 is provided with a plurality of claw receiving portions 41 and 42 on the top surface of the gantry near the receiving portion 4 corresponding to the plurality of claws 31 and 32. In the gantry 2 and the cartridge 3 having such a structure, the cartridge 3

The cartridge 3 can be securely fitted to the gantry 2 or the fitted state can be released by a simple operation to be performed.

As shown in FIG. 3B, communication holes 33 and 35 are provided at the bottom of the receiving portion 4. Therefore, as will be apparent to those skilled in the art by referring to FIG. 1 again, the water supplied from the connecting pipe or the water supply port passes through the communication hole 33 and the inlet 1 of the cartridge 3 (3A, 3B, 3C).
3 through which the non-woven cloth filter 23 and the partition plate 1
1 through the water-permeable material storage section 17 from bottom to top, from there through another non-woven cloth filter 25 and the upper support plate 7 to the upper gap of the cartridge 3 (3A, 3B, 3C). At the time, the flow changes from an ascending flow to a descending flow, descends in the shaft pipe 5, passes through the discharge port 15 and the communication hole 35, and is discharged to another connecting pipe.

The cartridges 3A, 3B and 3C are common in having the above-described basic configuration. However, in the water purifier according to the embodiment shown in FIG.
B and 3C store different water passage treatment materials according to different desired main purposes of the water passage treatment. Furthermore, each of the cartridges 3A, 3B, 3C has an improved configuration for another purpose of the present invention. Hereinafter, an example of each of the cartridges 3A, 3B, and 3C will be described in detail with reference to FIGS. In the following drawings, the same components as those in FIGS. 1 to 3 are denoted by the same reference numerals.

First, an example of the cartridge 3A will be described. FIG. 4 is a longitudinal sectional view showing an example of the cartridge 3A. At least the cartridge 3A whose main purpose is to remove residual chlorine includes coconut shell activated carbon as a water passage treatment material,
It contains calcium sulfite, a kind of sulfite.
In the cartridge 3A, a total of nine partition plates 5 partitioning between the partition plate 11 and the upper support plate 7 at substantially equal intervals in the axial direction.
1, 52 are provided. With this structure, a four-layer section 1 densely containing coconut shell activated carbon 55 as a water-permeable material.
01, 102, 103, 104, and six-layer compartments 105, 10 in which calcium sulfite as a water-passing treatment material is densely stored.
A plurality of cartridges 6, 107, 108, 109 and 110 are formed in the axial direction of the cartridge 3A to form a multilayer structure. In addition, 53 is a non-woven cloth filter, and 59 is a cap provided on the upper part of the cartridge.

FIG. 5 is a plan view showing the partition plate 51 (52). As shown in the figure, the partition plate 51 (52) is a disk having an outer diameter substantially equal to the inner diameter of the cartridge 3A, and has a center hole 57 having an inner diameter equal to the outer diameter of the shaft pipe 5 at the center thereof, and an outer edge. At a nearby eccentric position, there is a through hole 58 for passing water. As shown in FIG. 4, the shaft pipe 5 fits tightly into the center hole 57 of the partition plate 51 (52), while the outer edge of the partition plate 51 (52) is
Is divided into two adjacent sections that are communicated only by the through-hole 58 by being fitted to the inner wall of the. When such partitioning plates 51 (52) are arranged at predetermined intervals in the cartridge 3A to form a total of 10 layers, the partition plate 51 and the partitioning plate 52 define the position of the through hole 58 in the cartridge 3A. The direction of the other partition plate 52 with respect to the one partition plate 51 is substantially equal to 18 so as to be staggered (in the cross-sectional view of FIG.
Adjust to a position rotated 0 degrees.

In the cartridge 3A having the above-described structure, water rises through the non-woven cloth filter 23 and the partition plate 11 through the inlet 13 of the cartridge. Since the through-hole 58 penetrating the partition plate 51 that partitions the first-layer section 101 and the second-layer section 102 is provided at an eccentric position near the outer edge, the cartridge 3A in the section 101 is not provided. The water flow crossing in the axial direction of
A water flow flowing from right to left as indicated by the arrow) is generated and passes through the layer of coconut shell activated carbon 55. Water is in the first layer section 101
Flows through the through hole 58 into the second-layer section 102, but the second-layer section 102 and the third-layer section 103
The through-hole 58 penetrating the partition plate 52 for partitioning the cartridge 3A is positioned substantially symmetrically with respect to the axis of the cartridge 3A with respect to the through-hole 58 of the partition plate 51 through which water has previously passed. This time, a water flow (a water flow flowing from left to right as indicated by an arrow in FIG. 4) occurs in the direction of the water in the direction opposite to the water flow in the section 101. In this way, these ten layers of compartments 101, 102, 103, 104, 10
Through 5, 106, 107, 108, 109, and 110, water is sequentially passed through these sections so that water flows intersecting in the axial direction of the cartridge 3A are alternated.

In a conventional water purifier cartridge,
In most cases, water was allowed to pass straight through the water-permeable material having a laminated structure along the axial direction of the cartridge. Therefore, in order to increase the distance that water passes through the water passage treatment material, the length of the cartridge needs to be increased. On the other hand, according to the cartridge 3A having the above-described configuration, the direction of the water flow that intersects the axial direction of the cartridge in each section is changed, and the direction of the water flow is alternately changed from the bottom through the plurality of sections. Since the water is passed, the distance that the water passes through the water-permeable treatment material stored in each section can be lengthened. Accordingly, the processing capacity (residual chlorine removing ability) of the cartridge 3A whose main purpose is to remove residual chlorine can be further increased as compared with a cartridge of the same size as the conventional one, while securing the required amount of treated water. In addition, since the cartridge 3A contains coconut shell activated carbon and sulfite (calcium sulfite) as a water-passing treatment material, odor and turbidity can be removed in addition to residual chlorine.

Next, an example of the cartridge 3B will be described. FIG. 6 is a longitudinal sectional view showing an example of the cartridge 3B. Referring to FIG. 6, cartridge 3B mainly intended to remove unnecessary substances at least by ion adsorption has three types of ceramics (crystalline aluminosilicate-based porous fired granules) having different particle sizes as water passage treatment materials. Filter media). As shown in the figure, the cartridge 3B includes two partition plates 6 provided at a predetermined interval in the axial direction of the cartridge 3B.
1, the compartments 201, 20 containing the ceramics 62, 63, 64 as the water-passing treatment material in the cartridge 3B.
2, 203 are formed in three layers in the axial direction of the cartridge 3B to form a multilayer structure. Here, the partition plate 61 corresponds to FIG.
The partition plate 6 has the same structure as the partition plate 11 shown in FIG.
Immediately below 1 is a non-woven cloth filter.

The compartment 203 located in the upper layer is filled with the granular ceramic 64 having a small grain size so as to fill the compartment. On the other hand, the two compartments 201 and 20 located below
2, a large ball-shaped ceramic 62 having an average particle size of 5 mm to 6 mm and an average particle size of 2 mm to 3 m.
m, a predetermined amount of ball-shaped ceramics 63 each having a grain size larger than the granular ceramics 64 but smaller than the ball-shaped ceramics 62 are stored. In this case, the capacity of the ball-shaped ceramics 62 and 63 is adjusted to
01, 202, ball-shaped ceramics 62, 6
Spaces 65 and 66 are respectively secured so that 3 can move freely in the section. The preferred capacity of the ball-shaped ceramic is such that the ball-shaped ceramic occupies about half of the compartment as shown.

Water is introduced into the water inlet of the cartridge 3B having the above-described structure, and water is sequentially passed from the lower layer to the upper layer across the sections 201, 202, and 203. Then, first, in the lower section 201, the ball-shaped ceramic 62 having a large grain size, which has been deposited downward by gravity, is formed into a space 65 formed in the upper section of the section 201 by the water flow and the water pressure going upward from below. So that the ball-shaped ceramics 62 cause friction and / or collision. Ceramics are substances that cannot be removed by the cartridge 3A, for example, adsorb and remove suspended matters contained in water and adsorb and decompose water-soluble substances (for example, ammonia). The effect is synergistic, and this ion effect can be amplified when friction and collision between ceramics are generated without interruption. Next, in the middle section 202, the ball-shaped ceramic 63 similarly causes friction and / or collision, and amplifies the ion effect. Since the ball-shaped ceramic 63 has a smaller particle size than that of the ball-shaped ceramic 62 stored in the lower section 201, the water is passed through the middle section 202 from below to increase the size of the ball having a larger particle size. A desired ionic effect can be exerted on water that has passed through the gap without being sufficiently in contact with the ceramics 62. And finally, by passing water through the compartment 203 filled with the granular ceramic 64 having the smallest particle size of the upper layer, the water is surely brought into contact with the granular ceramic 64 and the ionic effect is reliably exerted. Can be. Therefore, the ionic effect can be further enhanced by the synergistic effect of the lower layer (lower and middle layers) containing such a ball-shaped ceramic and the upper layer filled with the granular ceramic.

Next, an example of the cartridge 3C will be described. FIG. 7 is a longitudinal sectional view illustrating an example of the cartridge 3C. The cartridge 3C whose main purpose is to provide at least a mineral content is filled with quartz diorenite (so-called Io stone) 81 having an average particle diameter of 5 mm to 7 mm, which is a water-permeable material, in the water-permeable material storage section. I do. An ionizer 90 is fixed to the upper part of the cartridge by a cap 82.

FIG. 8 shows an example of the ionizer 90.
(A) is a front view thereof, and (B) is a plan view thereof. The ionization device 90 includes a hemispherical convex lens 91 and a pair of dissimilar metal materials 93 and 94 having one end embedded and fixed in the convex lens 91 and extending in a bar shape while maintaining a predetermined interval.
The pair of dissimilar metal materials 93 and 94 are dissimilar metal materials having different ionization energies, preferably, a gold bar or a metal bar having at least a surface plated with gold, and a silver bar or a metal rod having a silver plated surface. Combination of A protruding collar 92 is integrally formed around the bottom of the convex lens 91.

Referring again to FIG. 7, the convex lens 91 of the ionizer 90 having the above-described configuration passes through the cap 82 provided on the upper portion of the cartridge 3C, and is exposed to the outside of the cartridge. The collar 92 is provided in the cartridge 3C.
And the cap 82.

According to the cartridge 3C having the above configuration,
Water passing through the layer of quartz diorenite 81
The flow changes from an ascending flow to a descending flow in the upper gap of C, and descends in the shaft pipe 5. Since the pair of dissimilar metal materials 93 and 94 having different ionization energies are arranged in a non-contact state in the upper gap and the shaft pipe 5, water passes therethrough to reduce the ionization energy generated between the dissimilar metal materials. Utilization can be used to ionize water to enhance the antibacterial effect (the effect of suppressing the growth of various bacteria).

In particular, according to the example of the cartridge 3C, since the convex lens 91 of the ionizer 90 is exposed to the outside of the cartridge, the light beam outside the cartridge is at least one of the pair of dissimilar metal materials 93 and 94 by the convex lens 91. Part can be focused. As a result, the ionizing energy can be amplified by converging the light beam outside the cartridge and capturing a small amount of infrared light into the cartridge and applying thermal energy to the pair of dissimilar metal materials 93 and 94.

The above operation will be described in detail by taking as an example a case where gold and silver are selected as the material of the pair of dissimilar metal materials. The ionization energy of gold (value for monovalent ions) is 9.23 eV, and the ionization energy of silver (value for monovalent ions) is 7.58 eV. Therefore, the difference in ionization energy generated between both metals is 9.23
(EV) −7.58 (eV) = 1.65 (eV), but this value changes depending on the surrounding environment. Utilizing this property, the convex lens 31 converges a light beam outside the cartridge, captures a small amount of infrared light into the cartridge, and imparts thermal energy to the dissimilar metal material of gold and silver, whereby ionization energy is amplified. Thus, the thermal conductivity of gold (315 W / m · K) and the thermal conductivity of silver (427
W / m · K), the difference in the ionization energies is larger, but the cooling action takes place by passing water through the portion where gold and silver have accumulated heat energy, and the ionization energy generated between the two metals Is amplified. As a result, water only passes between the two metals,
The antibacterial effect can be enhanced by ionizing water.

The present invention is not limited to the above-described embodiment, and it goes without saying that various changes can be made within the scope of the technical idea described in the claims.

[0049]

As described above, according to the present invention, the following useful effects can be obtained.

According to the first aspect of the present invention, at least three cartridges are used for each main purpose of the water flow treatment.
Different water treatment materials can be separated and stored in the cartridge for each main purpose. For this reason, various water treatment materials can be used up to their life, and the size of the cartridge can be reduced.
