Description

WATER ACTIVATION DEVICE

FIELD OF INVENTION

The present invention relates to a water activating device disposed in a tap water passage, particularly a water supply line, for activating tap water.

BACKGROUND OF THE INVENTION

[002] Groundwater produced from rain or snow in a mountainous region that has permeated the earth eventually becomes spring water and forms river headwaters. During this process, hydrogen bond clusters of water molecules are subdivided by infrared rays, negative ion effects, or magnetic effects of minerals and rocks. Alternatively, water receives electrons generated by friction between water molecules, which is caused by colliding with rocks or falling water. Thus, water becomes water having a specific function, such as reducing water. Such water has been known as water having an active power (generally known as "activated water" or "activation water").

It has been hard to say that such water is scientifically proven or publicly recognized. In fact, however, beneficial changes or responses are viewed as empirical, but to some extent broad when such water is used as process water or additive water for specific components or as drinking water.

However, it is very difficult to maintain an activated state of this activated water for a long period of time. Consequently, considerable variations are found in the effects of activated water. This fact greatly influences the falsity or veracity of the effects of activated water.

Various devices (hereinafter referred to as the "water activation device") having the following configuration have been put in place for the purpose of achieving more effective activation and maintaining an activated water state for a long period of time. For example, small lumps of a ceramic material in the form of a sphere, plate, or the like, which have been produced from burnt minerals (hereinafter referred to as "ceramic beads or the like"), are placed inside a device for pipe connection to each other. Alternatively, water is allowed to pass through a space of a static magnetic field or a dynamic magnetic field being produced.

For example, there has been disclosed a water activating device in which a plurality of boxes, each of which houses ceramic or similar spheres within and have defined water flow holes, are housed in a cylindrical housing which may be interposed in a water to tap water flow pipe (see, for example, Patent Literature 1).

There is also disclosed a water activating device in which grouped ceramic and infrared radiation discs are arranged having small communication holes defined therein, with multiple layers in a rotational manner within a casing that can be interposed in a tubing. water to tap water or the like with the invention of Patent Literature 1, while each ceramic disc is rotated by extreme blades formed on the disc (see for example, Patent Literature 2). LIST OF QUOTATIONS Patent Literature Patent Literature 1: JP-A-2001-058191 (p.3-5, fig. D

Patent Literature 2: JP-A-2000-107752 (p.2-3, fig. 1) SUMMARY OF THE INVENTION

Technical problem: However, water contact passages are limited in conventional water activating devices as disclosed above. Consequently, there is a problem that these water activating devices cannot produce activated water having sufficient active power.

For example, in the Water Activating Device of Patent Literature 1, a pressure loss may be caused to a water flow if ceramic or similar spheres are not evenly distributed. This way, water can become difficult for water to flow or it may become stagnant. Additionally, wear or abrasion of ceramic balls or the like, which is caused by mutual contact for a long time, decreases the activation effects. Therefore, there is the problem that maintenance is required as replacement or replenishment of ceramic or similar or cleaning spheres.

The water activation device of patent literature 2 is configured to rotate the ceramic discs to agitate a flow of water. Therefore, the contact between a water activating material and water is inevitably decreased relative to the case of Patent Literature 1 or the like, where ceramic or similar spheres are provided. Consequently, the effects of infrared rays, the effects of negative ions, or the magnetic effects may be deteriorated. In addition, the manufacturing costs of a ceramic disc having extreme blades are high, and a rotating mechanism can be damaged or similar over a long time of use so that a rotational state cannot be maintained in some cases. In such cases, there is a problem of degraded functions.

In addition, a fear that bacteria such as colon bacilli or Legionella proliferate in tap water has recently grown in conjunction with aging water distribution and deteriorating installation environments. The water activating device of both Patent Literature 1 and 2 does not have a sterilization function or a proliferation prevention function, or only has a low sterilization function or a low proliferation prevention function.

The present invention has attracted attention to the above mentioned problems. Therefore, the present invention provides a water activation device which aims to obtain activated water that can efficiently maintain its activated state with a limited passage length over a long period of time and also obtain activated water that has a sterilization function or a function. of proliferation prevention.

[0016] Problem Solution: [0017] To solve the above problems, a water deactivation device according to the present invention is configured as follows: Specifically, a water activation device has a housing that includes: a conductive body in a form of a cylinder, the body having a flow inlet side and a flow outlet side, conductive connecting means for allowing each flow inlet and flow outlet side of the body to communicate with an external water flow pipe, and a conductive cover member having an electrical insulating property and covering part or all of the connecting means and the body; water activating means including a number of water activating parts in the housing body in a state in which the water activating parts are kept out of contact with one another; an upstream canopy arranged at one end of the water activating means on the inlet side with one end being directed in the flow inlet direction, the upstream canopy having a conical shape; and a downstream canopy arranged at one end of the water activating means at the outflow side with one end being directed in the flow inlet direction, the downstream canopy having a conical shape.

[0019] Covering member can be grounded (grounded). With this configuration, positive ions in a plasma state generated within the water activation device (in a state in which positive ions (+) and electrons (-) are dissociated from each other) are discharged by grounding so that the electrons (-) remain.

In addition, for conical canopies, a single upstream canopy (a canopy on the inlet side) can be arranged roughly in a central portion with the tip being directed toward the inlet side. A plurality of downstream canopies (canisters on the outflow side) can be arranged on the outflow side with the tip being directed towards the inlet side. An opening angle of the downstream canopy tip can be adjusted to approximately 45 degrees. Although the opening angles mentioned above the canopies are great, the opening angles of the canopies are not limited to those mentioned above. Canopy opening angles can be adjusted to a certain extent.

In a preferred example, either one or both of the upstream canopy and downstream canopy is formed of an antibacterial material such as titanium, silver or copper. The upstream canopy and downstream canopy are preferably formed of a pure metal material. The upstream canopy and downstream canopy may be subjected to an upper surface forming coating treatment by a coating process. In a great example, the upstream canopy and downstream canopy are formed of a pure titanium alloy.

A stage can be formed by arranging a plurality of water activating parts in a cross section in a flow direction in a state in which the water activating parts are kept out of contact therebetween. The water activating means may have a multistage arrangement in which a plurality of stages are stacked in the flow direction.

The water activating parts arranged at each stage may be housed and held in a bowl-shaped holder having water permeability and having a substantially adjusted outer diameter at a horizontal cross-section of the body. The support may include a plurality of fins arranged on a lower part thereof. The fins may have an inclined surface to affect a flow by passing through a bottom of the holder to change a flow line. The fins may have the same inclination on the multi-stage arranged brackets in corporation with each other. In other words, a plurality of finned supports having the same shape or inclination are stacked and arranged in one body.

[0024] Water activation parts are formed of a material that has some effect on a water flow when in contact with the water flow. In a preferred example, a burnt body that primarily contains a multi-element mineral (ceramic, artificial tourmaline, or the like) is used for water activating parts. The burnt-out body has an outer shape of a cylinder having an axis parallel to an axis of the housing body. In addition, each of the water activating parts has a spiral groove or spiral crest formed on a circumferential outer surface thereof to change a direction of a flow. Additionally, a through hole that passes through the axis of the water activation part may be formed in the water activation part. As with the circumferential outer surface of the water activating part, a spiral groove or the like may be formed on a circumferential inner surface of the water activating part, if necessary, or to enhance functionality.

ADVANTABLE EFFECTS OF THE INVENTION

With the above configuration, a water activating device according to the present invention exhibits the following advantageous effects.

First, when water flowing from the incoming stream side collides with the upstream canopy, particular water is provided with rotation on a conical upstream canopy surface and is then accelerated. When the water particles leave a corner of the conical surface and a rear side of the canopy, the water particles are provided with rapid rotation. Consequently, the streams in which the water particles gather together become drastic vortex streams which move into the water activating means arranged downstream of the upstream canopy.

These vortex flows are brought into contact with the water activating means and changed to high efficiency activated water (transformation of an active power). Specifically, positive charges and electrons of water molecule atoms are released from each other by high-speed contact with water activation parts (high friction slip from the point of view of water particles). In the present application, this state is considered as a plasma state or a plasma oscillating state.

In addition, when the canopy is formed of an antibacterial material, primarily a titanium alloy, the canopy has flowing water ionization functions, preventing the proliferation of bacteria such as colon bacllli and Legionella, and reducing agricultural chemicals. . The present invention is considerably effective in improving water quality in a public bath or the like.

Additionally, a water activating device having a configuration according to the present invention may exhibit water quality enhancing effects. Specifically, chloramine (nitrogen compound) used as a chlorine substitute for disinfection can be reduced or removed. In addition, the trihalomethane generated by the reaction with chlorine may be reduced. Chloramine is generally considered to enhance the taste of tap water because it does not generate halomethane and does not emit odor. In addition chloramine could be removed if tap water was used for the disinfection of artificial dialysers for humans. In addition, monochloramine is poisonous to aquarium fish. Thus, chloramine does not always have beneficial aspects.

In addition, the downstream canopy disposed on a downstream side of the device can move water that has passed through the water activating means to the downstream piping while an activated water state is maintained for a long period of time. by accelerating with a conical downstream canopy surface and accelerating with the vortex flows generated at one corner of the conical surface.

In addition, as the water activating parts arranged in the housing have the above configuration, a surface area in which flowing water is brought into contact with the water activating parts is increased by a spiral groove or a spiral ridge formed on a circumferential outer surface of each of the water activation parts and (or) on a circumferential inner surface of a through hole in each of the water activation parts if the water activation parts are arranged in a flow passage. Additionally, the water activating part rotates about its axis and thus generates a large number of vortex flows in certain directions (right hand when viewed from the top view) within the flow passage. Consequently, flowing water can achieve activation effects efficiently with increasing contact surface area and vortex flows as described above. Particularly, vortex flows generate collision or friction electrons from water molecules to thereby promote activation. Thus, vortex flows contribute to efficient activation, most efficiently, where the length of the flow passage is limited.

In addition, the water activating parts are held in brackets having fins that can change water flow lines, and the brackets are arranged with multiple stages. Consequently, an area in which vortex flows are generated is maximized to thereby increase the degree of activation. In addition, a state of water activation can be maintained for a long period of time.

Additionally, as a plurality of downstream canopies having an acute opening angle as arranged on the outflow side, small vortex streams are added to the agitated streams that have passed through the enclosure and have been activated to a great extent. Therefore, chlorine detoxification is promoted. New activated water that might not be obtained by a conventional device can be obtained.

DETAILED DESCRIPTION OF THE INVENTION

Specific embodiments of a water activating device according to the present invention will be described below with reference to the accompanying figures.

A water activation device 1 according to the present embodiment is configured as follows: as shown in figures 1 and 2, the supports 3 each of which support a plurality of water activation parts 6 as means of Water activation primarily in an inner space of a housing 2 is arranged with multiple stages (in a state in which these supports 3 are placed adjacent to each other and stacked). An upstream canopy 4 is arranged on an upper side of the water activating means, and downstream canopies 5 are arranged on a lower side of the water activating means. This water activating device 1 is usually connected in series directly to water flow pipes 7, which form a tap water line, and are below ground. Alternatively, the water activating device 1 is connected to a medium pipe in a home.

The housing 2 includes a body 21 which is a cylindrical tubing made of metal of a predetermined length, an insulating member 22 having a thermal insulating property which substantially covers the entire circumferential outer surface of the insulating member 22. In addition, the connecting tubes 24 are arranged at both ends of the body 21 to cover the openings of the body 21.

[0044] These connection pipes 24 serve as means for connection to the water flow pipes 7. The connection pipes 24 are threaded and connected to the water flow pipes 7 hermetically to the water. When the connecting pipes 24 are attached to the body 21, insulating rings 25 having an electrical insulating property are circularly interposed between the connecting pipes 24 and both ends of the covering member 23 facing the connecting pipes 24. Thus, connecting pipes 24 and cover member 23 are electrically isolated from each other.

Each of the connection pipes 24 is fixed to the body 21 on a circumferential inner surface at an opening end with an internal thread 24c defined to screw and connect the connection pipe 24 to the water flow pipe 7 hermetically to the Water. The connecting pipe 24 at which flow tap water (the upper connecting pipe 24 in figures 1 and 2) forms a flow inlet port 24a, and the other connecting pipe 24 (the lower connecting pipe 24 in figures 1 and 2) forms a flow outlet port 24b. The housing 2 allows the flow inlet ports 24a and flow outlet 24b to be arranged on the same straight line or the same curved line so that a pressure loss at the time of flowing water is reduced.

In addition, a ground terminal 23a is connected to cover member 23 so as to ground positive loads (ground) generated on cover member 23. If the water activating device 1 is placed under ground, the terminal Earth 23a may be omitted.

Upstream canopy 4, downstream canopies 5, and resin supports 3 as means for supporting water activating parts 6 are disposed in the cylindrical inner space 26 of housing 2. These supports 3 are substantially adjusted on a circumferential inner surface of the inner space 26 of the housing 2 and arranged so that a plurality of supports 3 are coaxially connected to each other with multiple stages. The number of brackets 3 being arranged is properly designed in consideration of a tap water flow rate and activation efficiency.

Each of the supports 3 is in the form of a water permeable basin. More specifically, each of the brackets 3 includes a retainer 31 which is substantially disk-shaped, a connecting column 32 rising vertically from a central portion of the retainer 31 of a predetermined height, a cylindrical sidewall 33 formed to surround an outer corner of retainer 31 with a height less than the height of the connecting column 32, and three belt-shaped retainer walls 31a rising from the retainer 31 on an inner side of the sidewall 33. the retainer 31 has a large number of water flow holes 34 formed substantially in a mesh manner. The sidewall 33 has a tapered upper end that is open outward. Retainer 31, connecting column 32, side wall 33, and retaining walls 31a are integrally formed with each other.

Each of the brackets 3 supports one or more water activating parts 6 in place with retainer 31, side wall 33, and retainer walls 31a. Support 3 located right below flow inlet port 24a and support 3 located right above flow inlet port 24b support upstream canopy 4 and downstream canopies 5, respectively.

In each of the brackets 3, a connection hole 32a having a predetermined diameter is formed at an upper end of the connection column 32 with an internal thread 32b formed therein. Bracket 3 is coaxially fitted to other brackets 3 located above and below bracket 3. Thus, a multistage connection is provided. The upstream canopy 4 is secured to the connecting column 32 of bracket 3 located to the right below the flow port and inlet 24a by a screw 42.

The water flow holes 34 of bracket 3 are formed by a plurality of stirring fins 34a extending radially from the connecting column 32 to the side wall 33, and an inner ring 34b, an inner fin 34c, and two outer fins 34d connected to agitation fins 34a in a circumferential direction. Inner ring 34b, inner fin 34c and outer fins 34d are arranged concentrically with connecting column 32 at predetermined intervals in the order mentioned. The undersides of inner fin 34c and outer fins 34d are slightly longer than those of sidewall 33 and agitation fins 34a so that inner fin 34c and outer fins 34d protrude downwardly from sidewall 33 and stirring fins 34a.

Each of the stirring fins 34a has an inclined surface formed such that the water flows from an upper side (arrow a) are agitated right-hand (clockwise; arrow b) as observed in A top view. In addition, the inner fin 34c has a sloping surface formed so that water flows are deflected in an inward direction (arrow c). Each of the outer fins 34d has a sloping surface formed so that water flows are channeled in an outward direction (arrow d). The sloping surfaces formed on the fins 34a, 34c and 34d deflect water flowing in a stirring direction, an inward direction, and an outward direction, respectively, with respect to an inner space 26 of the housing 2. With one result, it is turbulence is generated in a state called agitation.

The arrangement and inner fin number 34c and outer fins 34d are not limited to the example of the present embodiment. For example, all fins may be formed by inner fins 34c, or conversely, all fins may be formed by outer fins 34d. Alternatively, the inner flap 34c may be disposed externally or the outer flaps 34d may be disposed internally. In this way, the arrangement and number of the inner fin 34c and outer fins 34d can be changed accordingly.

The upstream canopy 4, which is in the form of a circular cone with a point directed toward a flow inlet direction, is disposed within the holder 3 located to the right below the flow inlet port 24a. This upstream canopy 4 has a fixing hole 41 formed at the apex thereof. Screw 42 is inserted from a retaining hole 41 and tightened into the internal thread 32b formed in the connecting hole 32a of the connecting column 32, so that the upstream canopy 4 is fixed to the bracket 3. The upstream canopy apex 4 has an opening angle of approximately 90 degrees between the generating lines. The base of the circular cone is substantially the same diameter as that of the outer fin 34d located closer to the center of the holder 3 as seen in the top view.

In addition, a plurality of downstream canopies 5 (four downstream canopies in this example), each of which is in the form of a circular cone with one end directed toward the flow inlet direction, are disposed within the walls. of retainer 31a in bracket 3 located right above flow outlet port 24b. The downstream canopies 5 are kept out of contact between each other and at the connecting column 32 at equal intervals along a circumferential direction. Unlike the upstream canopy 4 located right below the flow inlet port, the apex of each downstream canopy 5 has an opening angle of approximately 45 degrees between the generating lines.

In the present embodiment, each of the upstream canopy 4 and downstream canopies 5 uses a titanium alloy. That is, when a titanium alloy is brought into contact with tap water, it exhibits a catalytic action to demonstrate a sterilization function or a proliferation prevention function against Colon bacilli or Legionella and to ionize chlorine to thereby render the water harmless.

One or more water activation parts 6 are arranged in retainer 31 of each of the supports 3 in addition to the supports having canopies 4 and 5. Each of the water activation parts 6 is a roughly cylindrical member and is produced by defining a through hole 62 including an axis 61 in a cylindrical burnt body that primarily contains a multi-element mineral (ceramic, artificial tourmaline or the like). Each of the water activating parts 6 has a height that is slightly less than that of the mounting column 32 of bracket 3. Each of the water activating parts 6 has a diameter that is approximately half a radius of retainer 31. O through hole 62 is formed to be slightly larger than the connecting column 32.

In addition, each of the water activating parts 6 has spiral ridges 63 formed on an outer circumferential surface and an inner circumferential surface. The spiral ridges 63 are agitated in the right hand direction (clockwise) as seen from the top view. These spiral ridges 63 substantially increase a surface area of the water trigger 6 and also change the water flows above the water trigger 6 (arrow a) in deflected flows that are roughly agitated according to the right hand (arrow and). In the present embodiment, each of the spiral ridges 63 is a continuous ridge formed on the outer circumferential surface or the inner circumferential surface of the water activating part 6. However, each spiral ridge 63 may be formed discontinuously.

In the present embodiment, the water activating parts 6 having the above configuration are held in the following manner within each of the supports 3, 3, ... arranged with multiple stages in the inner space 26 of the housing 2.

Specifically, a water activation piece 6 is fitted to the connecting column 32 of the bracket 31 through a through hole 62. A plurality of water activation pieces 6 (six activation parts in this embodiment) are arranged inside. of the retainer walls 31a provided around the connection column 32 in a state in which they are kept out of contact with each other. In other words, a plurality of water activating pieces 6, 6, ... are arranged at equal intervals along a circumferential direction within the holder retainer 3.

[0061] This arrangement of water activation parts 6 brings water flowing into uniform contact with the surfaces of water activation parts 6 and allows water activation parts 6 to rotate to the right (clockwise, arrow). f) the effects of spiral ridges 63.

OPERATION

Water activation device 1 having the above configuration operates as follows.

First, water flowing from the enclosure 2 flow inlet port 24a (arrow a) collides with the upstream canopy 4 and accelerates as it distributes. A large number of vortex flows are generated at one corner of the base of the circular cone to which water has distributed. When water collides with the upstream canopy 4, a catalytic action of an upstream canopy titanium alloy 4 prevents the proliferation of bacteria in the flowing water and ionizes chlorine thereby rendering the water harmless. In addition, an improvement in water quality of flowing water can be expected. Chloramine (nitrogen compound) and trihalomethane generated when an organic substance such as humine reacts with chlorine are reduced.

Examples of bacteria to be prevented from proliferation include colon bacilli and Legionella. The bacterial proliferation prevention effect was confirmed in an experiment where hot and cold water in which a liquid with certain diluted bacteria was mixed and was passed through the water activation device 1 of the present embodiment.

Then, when running water, which has passed through the upstream canopy 4 and reached holder 3 retainer 31, passes through the water flow holes 34, then clockwise stirred flows are added (arrow b) , inward deflected flows (arrow c) and outward deflected flows (arrow d) by agitation fins 34a, inner fin 34c and outer fins 34d. Consequently, a turbulent flow state is produced in which a plurality of clockwise agitated streams are primarily generated, that is, flowing water is being agitated in various directions with primary components of right agitation streams.

The vortex flows produced by the collision with the upstream canopy 4 and the water flows that have been formed in a turbulent flow state by the bracket 3 collide with the water activation pieces 6 retained in the retainer 31 of the bracket 3 in the subsequent stage, they pass between the water activating parts and reach the retainer 31. At that time, the arrangement in which the water activating parts 6 are kept out of contact with each other and the spiral ridges 63 formed on the circumferential surfaces. The inner and outer circumferential surfaces of the water activation parts 6 allow each of the water activation parts 6 to rotate right about their axis (arrow f) at a location where the water activation part 6 is positioned. , and affects water flows to form deflected flows that are agitated to the right (e).

Flowing water that has reached retainer 31 of holder 3 in a state of deflected flows that is agitated to the right is subjected to further agitation by water flow holes 34 and thus a turbulent flow state is formed. Thereafter, each time the flowing water passes through each of the multi-stage arranged brackets 3 into the inner space 26 of the housing, the same effects described above are applied to the flowing water.

Finally, when the flowing water passes through the support 3 having the downstream canopies 5, it is divided and accelerated by each of the downstream canopies 5. Additionally, fine vortex streams are added to the water flowing in one corner of the canopy. base of the circular cone of each downstream canopy 5. Then water flows out of flow outlet port 24b (arrow g).

As described above, the proliferation of bacteria (colon bacilli or Legionella) is prevented in water that has been flowing through the water activation device 1 by resonance effects between canopies having two shape types and the catalytic action of the alloy. titanium from these canopies. In addition, water hardness is decreased (decreased from 110 to 20).

In addition, hydrogen bonding clusters of water molecules in flowing water are subdivided by the infrared rays of water activation pieces 6. Flowing water receives electrons generated by friction between the water molecules and thus becomes if reducing water, or activated water. Regarding the degree of activation, the arrangement of the water activation parts 6 and the brackets 3 supporting those water activation parts 6 generate diverse turbulent flows in which a plurality of right stirring flows are deflected in and out. . In other words, such an arrangement exerts efficient stirring effects. Thus, the generation of negative charges is maximized, so that water has higher activation effects.

In addition to the above effects, since the shape (outer corners) of the brackets 3 is substantially adjusted on the inner circumferential surface of the inner space 26 of the housing 2, the amount of water flowing all passes through the water flow holes. 34 formed on retainer 31 of brackets 3 and collide with water activation parts 6. Therefore, the activation effects are amplified. The degree of activation can properly be adjusted by increasing or decreasing the number of brackets 3 arranged with multiple stages.

In addition, the electrical insulation is provided between the inner space 26 of the housing 2 and the cover member 23. Therefore, the water activating device 1 serves as a double layer electric capacitor. Positive charges separated from the electrons generated within the internal space are discharged via the grounding member 23a of the cover member 23. Consequently, electrical corrosion of the water activation device 1 or the like is prevented without reducing the activation effects on the body. Feasibility of other embodiments

Each of the water activating pieces 6 of the above embodiment has spiral ridges 63 formed on its outer circumferential surface and inner circumferential surface. However, these spiral ridges 63 may be formed by a combination of independent fins.

Further, each of the water activating parts 6 is a cylindrical member having a through hole 62 formed about an axis about which the water activating part 6 rotates. (For example, a plurality of through holes may be formed in a water activation piece 6 similar to a Japanese briquette).

In addition, the number of water activation pieces 6 arranged on each of the brackets 3 may appropriately be increased or decreased whenever the water activation parts 6 are kept out of contact with one another. The arrangement of the water activating parts 6 can be varied on each of the multi-stage arranged brackets 3.
