Description

The present invention relates to a water reformer cartridge and a water reformer.
More specifically, it is possible to prevent abrasion due to collision between the stored water reforming materials, and to ensure that the water to be treated is brought into contact with the water reforming material regardless of the flow rate of the water to be treated, and the filter is clogged. The present invention relates to a water reformer cartridge and a water reformer that are less likely to cause water.

  The deterioration of the global environment in recent years has also adversely affected water, which is indispensable for maintaining life. In the midst of concerns about adverse effects on water, that is, water contamination, there is a growing social interest in technologies that use various devices to modify water to make it suitable for beverages and the like.

  Alkaline ionized water (also referred to as alkali reduced water) has attracted attention as water suitable for beverages. Alkaline ionized water is known to have a low oxidation-reduction potential and a negative value, and the Ministry of Health, Labor and Welfare has been found to be effective for symptoms such as hyperacidity, chronic diarrhea, and indigestion.

As an apparatus for generating such alkaline ionized water, the present inventor has proposed a water reformer (purified ionized water generator) as shown in Patent Document 1 (see FIG. 10).
Japanese Patent No. 3223363

  The water reformer described in Patent Document 1 (see FIG. 10) is provided with an injection plate 93 that injects and circulates circulating water into a cylindrical body 92 filled with a water reforming material 91 (purifying material, electrolytic material). By making the water reforming material 91 circulate or floating / dispersing, the contact area / contact time between water and the water reforming material 91 can be increased, and efficient water reforming (alkali ionization) can be performed. It is.

  The above-described water reformer described in Patent Document 1 (see FIG. 10) is sufficiently practical that it can efficiently reform water, but there is room for further improvement with respect to the following points. It was.

  That is, since the water reforming material 91 is circulated or floating / dispersed together with water, the surface of the water reforming material 91 is worn away by collision between the water reforming materials 91. As a result, there is a disadvantage that the total amount of the water reforming material 91 used for water reforming is reduced and the replacement life of the water reforming material 91 is shortened.

  Further, as shown in FIG. 10, when the water reformer is installed sideways, the water reforming material 91 stays below the treatment chamber when the flow rate of the water to be treated is too small (the flow rate is slow and the water pressure is low). Therefore, the water modifier 91 does not exist in a part of the processing chamber (upper side in FIG. 10). In this case, water that cannot contact the water reforming material 91 is generated.

  Furthermore, since the filter 94 is provided only on the end side (short side direction) of the water reformer, the filter 94 is easily clogged when the water to be treated contains a lot of impurities such as sand. The amount of water was apt to drop.

  Furthermore, when the filter 94 is clogged or the water reforming material 91 is deteriorated, it is necessary to replace the filter 94 or the water reforming material 91. It could not be said that the structure could be easily disassembled for replacement.

(Object of the present invention)
Accordingly, an object of the present invention is to prevent abrasion due to collision between the stored water reforming materials and to allow the water to be treated to be in contact with the water reforming material regardless of the flow rate of the water to be treated. It is an object of the present invention to provide a water reformer cartridge and a water reformer that are less likely to cause clogging.

  Another object of the present invention is to provide a water reformer cartridge and a water reformer that can easily perform replacement work of a water reforming material and a filter.

The means of the present invention taken to achieve the above object are as follows.

  The “filter” to be used is not particularly limited, and a known filter can be adopted. For example, an adsorbent such as activated carbon (granular activated carbon, fibrous activated carbon, coconut shell activated carbon, etc.) is solidified with a binder or the like, and is formed into a cylinder by winding a fibrous activated carbon sheet. be able to.

  As the “water modifier” to be used, in addition to magnesium, for example, calcium, iron, zinc, cobalt, manganese and other minerals, limestone, dolomite, marble, coral sand, shell, bone, barley stone, solar stone, Examples include, but are not limited to, Soyoishi, ceramics, charcoal (activated carbon, Bincho charcoal, coconut husk charcoal, bamboo charcoal, etc.), filtration membranes (hollow fiber membranes, reverse osmosis membranes, flat membranes), and ion exchange resins. Not what you want.

  In addition, the shape of the “flow hole” of the water flow plate is not particularly limited, and for example, a circular shape, an elliptical shape, a rectangular shape, a square shape, or other polygonal shape or irregular shape (irregular shape). The thing etc. can be mentioned.

(Work)
The water reformer cartridge according to the present invention (hereinafter sometimes simply referred to as “cartridge” in the present specification) operates as follows.
A cartridge is accommodated in a casing to constitute a water reformer. And the water supply pipe introduced from the outside of the casing is directly or indirectly connected to the water passage portion of the cartridge, and water before reforming (hereinafter referred to as treated water) is introduced into the casing. The water to be treated flows from the outer peripheral surface of the filter formed in a cylindrical shape to the hollow portion, and is reformed by the water reforming material filled in the hollow portion. The reformed water flows to the other end side of the hollow portion, is taken out of the casing through the water supply pipe from the water passage portion, and is used.

  Moreover, water can be reformed by flowing water in the opposite direction to that described above. In this case, the water to be treated brought into contact with the water reforming material always passes through the filter, so that the water reforming material can be reliably filtered by the filter, and the water reforming material may be mixed into the water after the reforming. There is no.

  Thus, the present invention has a structure in which the water to be treated is in contact with the water modifier filled in the hollow part while flowing through the hollow part of the filter. Unlike the one described in Patent Document 1, It does not have a structure in which the water modifying material is circulated or floated / dispersed together with the water to be treated.

  Regardless of the flow rate of the water to be treated, the water to be treated flows into the hollow part of the filter and always comes into contact with the water reformer filled in the hollow part.

  Further, since the filter is disposed so as to surround the water reforming material from the outer peripheral direction, the water to be treated passes through the filter and comes into contact with the water reforming material, or the water that has contacted the water reforming material covers the filter. Pass through.

  A water passage plate having a required number of water passage holes is provided on the other end side of the hollow portion, and the water passage holes are provided in a direction in which water can circulate. Circulates and flows smoothly as water flows in a certain direction.

  In the case where the water modifier is magnesium, magnesium comes into contact with the water to be treated, and as shown in the following chemical formula 1, magnesium reacts with water to produce magnesium hydroxide and hydrogen, and alkali ion water and Become.

  In the case where the closing portion is detachably provided on the filter, the closing portion is removed and one end side of the hollow portion is opened. Thereby, the replacement | exchange operation | work of the water modifier filled in the hollow part can be performed easily.

The present invention has the above-described configuration and has the following effects.
(A) In the water reformer cartridge according to the present invention, the water to be treated has a structure in contact with the water reforming material filled in the hollow portion while flowing through the hollow portion. The structure is not designed to circulate or loosen / disperse the material. Therefore, it can prevent that the surface is worn out by the collision of water modifiers.

  In addition, if the water reformer cartridge according to the present invention is used, the water to be treated flowing into the hollow portion of the filter must be brought into contact with the water reformer filled in the hollow portion regardless of the flow rate of the water to be treated. Can do.

  Further, in the water reformer cartridge according to the present invention, the filter is disposed so as to surround the water reforming material from the outer peripheral direction, and the water to be treated is brought into contact with the water reforming material through the filter, or the water reforming material. The water that comes into contact with the material passes through the filter. Therefore, as compared with a structure in which the filter is provided only on the end side of the cartridge and water to be treated is passed from the end side, the filter area with respect to the entire cartridge is large, so that the filter is not easily clogged.

(B) A water flow plate having a required number of water flow holes is provided on the other end side of the hollow portion, and the water flow holes are provided in a direction in which water can be circulated. The passed water circulates and flows in a constant direction. Thereby, water flows smoothly as a whole, and efficient water reforming becomes possible.

(C) In the case where the water modifier is magnesium, magnesium is brought into contact with water to be treated, so that magnesium reacts with water and magnesium hydroxide and hydrogen are generated. Thereby, the alkali ion water which has the oxidation-reduction potential and pH equivalent to an electrolyzed water manufacturing apparatus can be produced | generated, without utilizing electrolysis.

(D) In the case where the closing member is detachably attached to the filter, the water modifying material in the filter can be easily replaced by removing the closing member.

(E) According to the water reformer of the present invention, the water reformer cartridge having the above-described effects can be used to efficiently reform the water to be treated, and the water reformer and the filter When exchanging, since the whole cartridge can be exchanged for a new one, the exchanging operation is easy.

Hereinafter, each component of the cartridge 1 will be described in detail step by step.

  The filter 3 includes an adsorbing body 31 formed in a cylindrical shape and a cylindrical accommodating body 32 provided in a hollow portion of the adsorbing body 31. Both the adsorbent 31 and the container 32 have water permeability.

  The adsorbent 31 is obtained by molding activated carbon (fibrous activated carbon and coconut shell activated carbon) into a cylindrical shape using a known binder, and can independently maintain the shape. The adsorbent 31 can be formed by a known technique such as a method in which activated carbon and a binder are mixed and baked, or a method in which activated carbon and a binder are formed into a slurry and formed by extrusion and baked.

  The outer peripheral surface portion and the inner peripheral surface portion of the adsorbent 31 are covered with non-woven fabrics 312 and 312 having water permeability. The nonwoven fabrics 312 and 312 can be fixed by an adhesive, heat sealing, or the like. The surface and the inner surface of the formed adsorbent 31 are protected by the nonwoven fabrics 312 and 312.

  The container 32 is made of a synthetic resin (for example, polypropylene). A large number of small water passage holes 321 are arranged in a lattice pattern in the peripheral wall portion of the container 32 and open. The water reforming material 4 is filled in a hollow portion that is a hollow portion of the container 32.

  As shown in FIG. 4, annular packing plates 33 and 33 each having an open center are fixed to the left and right end surfaces of the adsorbent 31. The packing plate 33 is made of synthetic resin (for example, made of polyethylene foam sheet) and does not have water permeability. Due to the opening 331 of the packing plate 33, the hollow portion of the adsorbent 31 is opened.

  A cap-type lid 5 is attached to one end side (left end side in FIG. 3) of the filter 3 with a slight fit. One of the constituent members of the lid 5 is the above-described closing member 51, and one end side of the hollow portion of the filter 3 can be closed by the closing member 51.

  The closing member 51 is detachable by screwing with the main body 52 of the lid 5. Reference numeral 511 shown in FIG. 4 indicates a recess for inserting a finger when the closure member 51 is screwed and attached. If the closing member 51 is removed from the main body 52 in the state shown in FIG. 3, the replacement work of the water reforming material 4 in the filter 3 can be easily performed.

As described above, the water flow member 6 (see FIG. 5) is a cap-type lid. Water passage member 6 is provided with a neck portion 61 having a passage Mizuguchi 610. A thread is formed on the outer peripheral surface of the neck portion 61 and is screwed into a neck portion 243 (see FIG. 2) of the first lid body 24 of the casing 2 described later.

  The depth of the inner peripheral wall portion 62 of the water flow member 6 (see FIG. 4) is formed slightly deeper, and the first spacer 81, the water flow plate 7 and the second spacer 82 are placed between the filter 3 and the above. It can be accommodated in a sandwiched state. The water flow plate 7 is accommodated while being sandwiched between the first spacer 81 and the second spacer 82.

FIG. 6 is a plan view explanatory view of the water flow plate main body before fixing the net body,
FIG. 7 is a schematic explanatory view showing a part of a cross section corresponding to the II portion of FIG. 6.
With reference to FIG. 4 thru | or FIG. 7, the structure of the water flow board 7 is demonstrated.

  As shown in FIGS. 4 and 5, the water flow plate 7 includes a circular water flow plate main body 71 made of a synthetic resin and a stainless steel net body fixed so as to cover the entire surface of the water flow plate main body 71. 72. In the present embodiment, the net body 72 is fixed to the water flow plate main body 71 by welding with the water flow plate main body 71.

  As shown in FIG. 5 (showing the water flow plate main body 71 before the net body 72 is fixed), the water flow plate main body 71 is provided with a required number of water flow holes 711 therethrough. As shown in FIG. 6 (showing the water flow plate main body 71 before the net body 72 is fixed), the water flow plate main body 71 is provided with a total of 12 water flow holes 711 in a radial manner. It is not limited to arrangement and number.

  Each water passage hole 711 is provided such that the water passage direction is inclined with respect to the front and back surfaces of the water passage main body 71 (see also FIG. 7). Thereby, since the water which passes the water flow board 7 (refer FIG. 5) can be circulated and it can be set as the water flow of a fixed direction, water can be passed smoothly. In addition, when water flows smoothly due to high water pressure or the like, the water passage hole 711 may be provided in a direction perpendicular to the front and back surfaces of the water plate main body 71.

  The water flow plate main body 71 (see FIG. 6) includes an annular convex portion 712 at the center portion and a wall portion 713 at the peripheral portion thereof. As shown in FIG. 5, the convex portion 712 and the wall portion 713 are formed one step higher than the top portion of the water passage hole 711. The net 72 is fixed to the convex portion 712 and the wall 713 of the water flow plate main body 71 and is not in close contact with the top of the water flow hole 711.

  With such a configuration, the net 72 can prevent the water reforming material 4 pushed by water pressure from blocking the water passage hole 711. As a result, since water flows smoothly through the water passage hole 711, a decrease in the amount of water flow can be prevented.

  The first spacer 81 and the second spacer 82 are disposed on the front and back surfaces of the water flow plate 7, so that a space is formed on the front and back surfaces of the water flow plate 7. Thereby, water flows smoothly through the space.

[Case 2]
Next, the casing 2 that houses the cartridge 1 will be described with reference to FIGS. 1 and 2.
The casing 2 is made of reinforced plastic (FRP: fiber reinforced plastic) and includes a cylindrical casing body 23. A first lid body 24 having a circular shape in plan view is attached to an opening (reference numeral omitted) on one end side (right end side in FIG. 2) of the casing main body 23 by slightly fitting. Reference numeral 241 indicates an O-ring.

  In FIG. 1, the code | symbol 25 has shown the fixed piece formed in the crescent moon shape. The pair of fixing pieces 25, 25 formed symmetrically is fitted into a ring-shaped groove 231 (see FIG. 2) formed on the inner peripheral surface of the casing body 23 and fixed with a set screw 26. The first lid 24 cannot be removed from the casing body 23.

  A screw hole 242 is formed in the center of the first lid 24. The connector 22 is screwed and fixed to one end side of the screw hole 242 (outside of the casing 2). A water supply pipe such as a water pipe is connected to the connector 22 from the outside. The water passage member 6 of the cartridge 1 is screwed and connected to the neck portion 243 which is the other end side (inside the casing 2) of the screw hole 242.

  A second lid body 27 having a circular shape in a plan view is attached to the opening (not shown) on the other end side (left end side in FIG. 2) of the casing main body 23 by slightly fitting. Similar to the first lid body 24, an O-ring 271 is attached to the second lid body 27 so that it cannot be removed from the casing body 23 by the fixing pieces 25, 25 and the set screw 26.

  A screw hole 272 is formed at the center of the second lid 27, and the connector 21 is screwed and fixed to one end side (outside of the casing 2) of the screw hole 272. The connector 21 is connected to a water pipe or the like that is a water guide portion from the outside.

(Work)
The cartridge 1 and the water reformer A1 using the cartridge 1 operate as follows.
First, the second lid body 27 provided with the connector 21 is fixed to one end side (the left end side in FIG. 2) of the casing body 23. Next, the cartridge 1 is attached to the first lid 24 before the first lid 24 is fixed to the other end side (the right end side in FIG. 2) of the casing body 23. And the cartridge 1 and the 1st cover body 24 are inserted in the casing main body 23, the 1st cover body 24 is fixed to the other end side of the casing main body 23, and water reformer A1 is comprised.

  Then, a water supply pipe (not shown) is connected to the connector 22 of the first lid 24, and a water conduit (not shown) is connected to the connector 21 of the second lid 27, so that the water to be treated is introduced into the casing 2. To do.

  The water to be treated passes through the hollow portion from the outer peripheral surface of the filter 3 (see FIG. 3) of the cartridge 1 and is reformed by the water reforming material 4 filled in the hollow portion. The reformed water flows to the other end side of the hollow portion, is taken out from the casing 2 through the water supply pipe through the water supply member 6, and is used.

  Thus, the cartridge 1 according to the present embodiment has a structure in which the water to be treated is in contact with the water reforming material 4 filled in the hollow portion while flowing through the hollow portion of the filter 3. The water reforming material 4 is not structured to circulate or float / disperse. Therefore, it is possible to prevent the surfaces of the water reforming materials 4 from being worn away by collision.

  Further, in the cartridge 1 according to the present embodiment, the water to be treated which has flowed into the hollow portion from the outer peripheral surface of the filter 3 is always brought into contact with the water reforming material 4 filled in the hollow portion regardless of the flow rate of the water to be treated. Can do.

  Further, since the filter 3 is disposed so as to surround the water reforming material 4 from the outer peripheral direction, the water to be treated comes into contact with the water reforming material 4 through the filter 3. Therefore, the filter 3 has a larger area with respect to the entire cartridge 1 than the structure in which the filter 3 is provided only on the end side in the longitudinal direction of the cartridge 1 and water to be treated is passed from the end side. Clogging is difficult to occur.

  As shown in FIG. 5, in this embodiment, since the water flow plate 7 having the water flow holes 711 is provided on the drain side (the other end side of the hollow portion), the water passing through the water flow plate 7 is recirculated. The water flows in a certain direction. Thereby, water flows smoothly as a whole, and efficient water reforming becomes possible.

  If the water flow plate 7 is not provided, the water flowing from the outer peripheral surface portion of the filter 3 to the hollow portion flows straight in the axial direction as it is and is discharged from the water flow port 610. For this reason, in the vicinity of the inner corner of the water flow member 6, there will be a place where water does not stay and flow. Therefore, in the present embodiment, by providing the water flow plate 7 capable of circulating water, the water can be smoothly flowed without being retained.

  Furthermore, since magnesium is the main material of the water reforming material 4, magnesium reacts with the water to be treated, and magnesium hydroxide and hydrogen are generated. Thereby, the alkali ion water which has the oxidation-reduction potential and pH equivalent to an electrolyzed water manufacturing apparatus can be produced | generated, without utilizing electrolysis.

  Since the closing member 51 is detachably provided on the filter 3, the water modifying material 4 in the filter 3 can be easily replaced by removing the closing member 51.

  Further, when the water reforming material 4 and the filter 3 are replaced, the cartridge 1 can be replaced with a new one, so that the replacement work is easy.

  If the water conduits and water supply pipes (both not shown) connected to the connectors 21 and 22 shown in FIG. 2 are attached in reverse, water flows in the opposite direction (from right to left in FIG. 2). Water can be modified. In this way, the water to be treated is reformed by the water reforming material 4 filled in the hollow portion of the filter 1 through the water passage member 6 of the cartridge 1, and the water after reforming is supplied to the filter 1. It flows from the hollow portion to the outer peripheral surface and is taken out of the casing 2 through the water supply pipe. The same applies to Example 2 described later.

  In this way, if the water after reforming brought into contact with the water reforming material 4 is always passed through the filter 3, even if the powdery or fine water reforming material 4 is used, the water Since the water reforming material 4 contained in the water can be reliably filtered by the filter 3, there is no fear that the water reforming material 4 is mixed into the water after reforming.

FIG. 8 shows a second embodiment of the water reformer according to the present invention, and is a side view explanatory view showing a cartridge inside by cross-sectioning the water reformer,
FIG. 9 is a bottom view explanatory view of the water reformer shown in FIG.
In addition, the same code | symbol is attached | subjected and shown to the same or equivalent location as Example 1. FIG. Moreover, about the location shown in Example 1, description is abbreviate | omitted and difference is mainly demonstrated.

  In the water reformer A2, unlike the water reformer A1 according to the first embodiment, as the connectors 21a and 22a on the water supply unit side and the water guide unit side, pipe joints bent at an angle of about 90 degrees ( Elbow) is used. And the opening part of the both ends side of the casing main body 23 is covered with the cap-type lid bodies 28 and 28. Each lid 28 has a notch 281 for introducing a water pipe or the like connected to the connectors 21a and 22a.

  Thus, in this embodiment, the connectors 21a and 22a are bent at an angle of about 90 degrees, and the connectors 21a and 22a are hidden by the lids 28 and 28. Therefore, the water reformer A2 that requires the replacement of the cartridge 1 can be installed so as to be visible, and the unsightly water pipe can be installed under the floor so as to be hidden from view.

  When the water reformer A2 is buried in the ground, the lids 28 and 28 can protect the soil from entering the casing 2.
