Description

  The present invention relates to a water discharge device that removes chlorine contained in, for example, tap water and generates negative ions.

Currently, tap water used every day is sterilized and sterilized with chlorine to ensure its hygiene. In this case, the chlorine remaining in the tap water in a state of disinfection is called residual chlorine, and there are two types of residual chlorine: free residual chlorine and combined residual chlorine. Free residual chlorine has three modes of chlorine (Cl ₂ ), hypochlorous acid (HClO), and hypochlorite ion (ClO ⁻ ), all of which have strong sterilizing power. Depending on the pH and the temperature, the ratio of the presence varies. In addition, the bond residual chlorine includes modes such as monochloramine (NH ₂ Cl), dichloramine (NHCl ₂ ), and trichloramine (NCL ₃ ) bonded to nitrogen, and these modes also depend on the pH of tap water. The proportion of whether it is present in the embodiment varies.
As an indicator of the residual chlorine concentration in tap water, free residual chlorine concentration or combined residual chlorine concentration is used. For example, in Tokyo and Osaka, etc., depending on the weather and rainfall at that time, The concentration of free residual chlorine is about 0.6 to 0.9 mg (0.6 to 0.9 ppm when the specific gravity of tap water is 1).

  Such residual chlorine in tap water, for example, may cause damage to the skin or hair when directly touched, and it is desirable to remove it as much as possible. It can be removed. However, for example, when tap water is used as it is as a shower or the like, even if the tap water is heated (for example, heated to about 35 ° C. to 42 ° C. lower than the boiling state), it remains in the tap water. Chlorine is hardly removed and remains contained in tap water.

Therefore, conventionally, various shower water purifiers that remove residual chlorine in tap water using a filter medium such as activated carbon or calcium sulfite provided therein have been considered (see Patent Document 1 and Patent Document 2). .
For example, the water purifier for shower shown in Patent Document 1 has a communication part with a hose that supplies a shower head and tap water at the upper part and the lower part, respectively, and is interposed between the shower head and the hose. Used in communication. Such a water purifier has a built-in filter medium using activated carbon (for example, coconut husk), thereby removing residual chlorine in tap water.

However, with such a water purifier, the filter medium gradually becomes clogged as it is used, and the water purification capacity (residual chlorine removal capacity) decreases, so it is necessary to periodically replace the water purifier itself. It must be done and running costs are incurred.
In addition, in the purified water with filter media using such activated carbon (for example, coconut shells), since the water flow of the tap water is once blocked, a decrease in water pressure cannot be avoided, and when using tap water as a shower, There is a possibility that the momentum of the water (hot water) to be ejected will be reduced and the usability will deteriorate.

Moreover, for example, in the shower water purifier shown in Patent Document 2, a cartridge containing a filter medium having an activated carbon layer and a calcium sulfite layer is built in the shower head, thereby removing residual chlorine in tap water. .
However, even in such a water purifier, since the water purification capacity (residual chlorine removal capacity) is reduced due to clogging of the filter medium due to use, it is necessary to periodically replace the cartridge, and the water purifier for shower shown in Patent Document 1 described above is required. In the same manner, replacement work and running costs will occur.
Similarly, the momentum of the water (hot water) ejected from the shower head is reduced, and there is a possibility that the usability is deteriorated.

  In addition, although the water purifier for shower shown by patent document 1 and patent document 2 mentioned above each aims at purification | cleaning (for example, removal of the residual chlorine in tap water), it is clean when using a shower. From the viewpoint of exerting the action, other than means for purifying tap water, for example, means for generating negative ions can be considered. For example, the shower head shown in Patent Document 3 is provided with a guide member (for example, a blade member) for controlling the flow of tap water in the shower head main body on the side of the tap water supply in the shower head main body. By giving a swirling flow to the flowing tap water, the cluster structure of water molecules in the tap water is subdivided, and negative ions are generated (released) in the air when water (hot water) is ejected from the shower head.

However, in such a shower head, the number of ejected negative ions varies depending on the strength (swirl speed) of tap water flowing in the shower head, and the strength of the swirl flow (swirl speed) It depends on the pressure and amount of tap water flowing in the head.
Therefore, for example, when the pressure or amount of tap water flowing in the shower head is large, the strength (swirl speed) of the swirling flow of tap water flowing in the shower head is increased and generated (released). The number of negative ions also increases. On the other hand, for example, when the water pressure or amount of tap water flowing in the shower head is small, the strength (swirl speed) of the tap water flowing in the shower head decreases accordingly, and is generated (released). ) The number of negative ions is also reduced.

As described above, in the conventional shower head, when water (hot water) is ejected from the shower head, the number of negative ions generated (released) in the air is the water pressure or amount of tap water flowing in the shower head. Therefore, a predetermined number of negative ions may not be stably generated.

Moreover, the material of the water discharge part 6 of the shower head S is not specifically limited, Arbitrary materials (for example, resin, a metal, etc.) can be applied.

  In this embodiment, the silver ion discharge | release mechanism of the water purification process part 10 is provided with the coil-shaped member 12 formed with silver as an example, and when the tap water passes the coil-shaped member 12, the said coil-shaped member 12 is provided. When contacting, silver ions are released from the coil-shaped member 12 into the tap water. In this case, the coil-shaped member 12 should just be formed with the silver containing raw material which can discharge | release silver ion in tap water. In this case, as the silver-containing material, for example, various silver compounds may be used in addition to silver. However, since the amount of silver ions released increases and decreases in proportion to the silver content, the silver content is It is preferable to form with many materials. Instead of integrally forming the coil-shaped member 12 with such a silver-containing material, for example, various metals may be formed in a coil shape, and the surface thereof may be plated with silver to constitute the coil-shaped member 12. .

  In the present embodiment, the diameter of the coil-shaped member 12 changes from one end to the other end, and FIGS. 2A to 2C show examples of the shape. ing. In this case, the diameter of the coil-shaped member 12 gradually decreases from the one end side 12a (the upper side of FIGS. 2A and 2B) to the intermediate portion (throttle portion 12c), and the intermediate portion (throttle portion) The diameter is gradually increased from the portion 12c) to the other end side 12b (the lower side of FIGS. 2A and 2B). That is, it is formed so as to form one drum shape with both ends 12a and 12b having a maximum diameter and an intermediate portion (throttle portion 12c) having a minimum diameter.

  According to such a shape, since the contact area (region) of the coil-shaped member 12 with respect to the tap water passing through the water passing portion 4 can be increased, silver ions can be uniformly released into the tap water. As a result, chlorine in tap water can be efficiently removed.

  In addition, the form of the coil-shaped member 12 is not limited to the structure mentioned above, For example, the number and magnitude | size of the coil-shaped member 12, the number of turns of a spiral, and direction are arbitrary according to a use purpose or a use environment. It is possible to design the number, size, number of windings and direction. For example, FIGS. 5A and 5B show the configuration of a shower head S provided with a coiled member 12 according to a modification of the present embodiment as a silver ion release mechanism.

  The coil-shaped member 12 according to the first modification shown in FIG. 5A is changed from one end side 12a (upper side of FIG. 5A) to the other end side 12b (lower side of FIG. 5A). On the way to the end, it has a narrowed portion 12c and an expanded portion 12d. The diameter gradually decreases from one end side 12a to the narrowed portion 12c, and the diameter gradually increases from the narrowed portion 12c to the expanded portion 12d. The diameter is gradually reduced from the expanded portion 12d to the other end side 12b. That is, the one end side 12a and the extended portion 12d are formed to have a maximum diameter, and the other end side 12b and the throttle portion 12c have a minimum diameter. The upper and lower sides may be reversed so that the one end side 12a has the minimum diameter and the other end side 12b has the maximum diameter.

  Further, the coil-shaped member 12 according to the second modification shown in FIG. 5 (b) has an end 12a (the upper side of FIG. 5 (a)) to the other end 12b (the lower side of FIG. 5 (a)). ) Has an upper diaphragm portion 12c, an expanded portion 12d, and a lower diaphragm portion 12e. The diameter gradually decreases from one end side 12a to the upper diaphragm portion 12c, and the upper diaphragm portion 12c expands. The diameter gradually increases to the portion 12d, the diameter gradually decreases from the expanded portion 12d to the lower throttle portion 12e, and the diameter gradually increases from the lower throttle portion 12e to the other end side 12b. It is formed as follows. That is, it has an integrated configuration in which two coil-shaped members 12 according to this embodiment described above are connected in series. In addition, it is good also as a separate structure which has arrange | positioned two coil-shaped members 12 which concern on this embodiment mentioned above in series instead of an integral structure.

  Further, in the present embodiment, the silver ion release mechanism of the water purification treatment unit 10 also includes a mesh member 14 formed of silver, and FIGS. 3A and 3B show an example of the shape. Has been. In this case, the mesh member 14 has a disk shape composed of the mesh portion 14a and the edge portion 14b. The annular edge portion 14b surrounds the outer periphery of the mesh portion 14a, and the coil-like member 12 as a whole. It is formed to have the same diameter as the maximum diameter. When the tap water contacts the mesh member 14 while passing through the mesh member 14, silver ions are released from the mesh member 14 into the tap water.

  The mesh member 14 is only required to be formed of a material containing at least silver, like the coil member 12, and may be, for example, various silver compounds in addition to silver. A material with a large amount is preferred. Moreover, what plated silver on various metals may be used.

  The form of the mesh member 14 is not limited to the above-described configuration. For example, the number, shape, and size of the mesh member 14 and the shape and fineness of the mesh depend on the purpose of use and the use environment. Any number, shape and size, mesh shape and roughness can be designed. For example, FIG. 1B shows an example of a configuration in which four mesh members 14 are arranged as a silver ion release mechanism.

  In this case, two mesh members 14 are provided one by one on the water discharge part 6 side from the one end side 12a of the coiled member 12 and one on the water inlet part 2 side from the other end side 12b of the coiled member 12, respectively. The two mesh members 14 are provided one between the one end side 12a and the other end side 12b of the coil member 12, and these four mesh members 14 are arranged so as to be arranged at substantially equal intervals. ing.

  According to such a configuration, in addition to the coil-shaped member 12, the mesh-shaped member 14 is further provided, so that the contact area (region) with respect to the tap water passing through the water passing portion 4 is further increased. The amount of released ions can be improved.

  Moreover, as shown in this embodiment and each modification mentioned above, the tap water which passes the inside of the water flow part 4 is made into the coil-shaped member 12 by applying the coil-shaped member 12 which changed the magnitude | size of the diameter. When passing through the tap water, the tap water can be uniformly contacted and the tap water can pass smoothly, and silver ions can be released more efficiently (more) in the tap water.

According to such a silver ion release mechanism (coiled member 12 and mesh-like member 14), a large amount of silver ions is released into tap water, thereby efficiently removing the silver ions and residual chlorine in tap water. Since the reaction can be performed uniformly, chlorine in tap water can be removed reliably and in a short time.
Moreover, according to the silver ion release mechanism (coiled member 12 and mesh member 14), silver ions can be released into tap water semi-permanently. For example, chlorine removal using a filter medium (for example, activated carbon or calcium sulfite) cannot maintain a constant residual chlorine removal ability over a long period of time, and maintenance and replacement of the filter medium are necessary. This silver ion release mechanism is not necessary, and can exhibit a certain chlorine removing ability over a long period of time.

  Thus, the periodic replacement work (maintenance) of the coil-like member 12 and the mesh-like member 14 becomes unnecessary, so that a low-cost shower head S that does not generate running costs can be realized, and the silver ion release efficiency can be realized. Improved and easy removal of chlorine in tap water, easy-to-use and comfortable (for example, the hair after shampooing will be smooth without rinsing) ) Can be provided.

Here, the result of verifying the water purification ability (residual chlorine removal ability) of the silver ion release mechanism (coiled member 12 and mesh member 14) of the water purification treatment unit 10 according to the present embodiment will be described below. In this case, in an environment of room temperature 23 ° C. and humidity 55%, 1 L of water (free residual chlorine concentration 1 ppm) is taken in from the water inlet 2 of the shower head S, passed through the water passage 4 and flows out from the water outlet 6. The free residual chlorine of the spilled tap water was measured, and the verification was repeated 5 times. As a result, the free residual chlorine concentration of each runoff tap water was 0.51 ppm, 0.47 ppm, 0.57 ppm, 0.34 ppm, 0.49 ppm, and the average free residual chlorine concentration was 0.48 ppm.
Therefore, it was verified that the silver ion release mechanism (coiled member 12 and mesh member 14) of this embodiment has a water purification ability (residual chlorine removal ability) that reduces free residual chlorine by 52%.

In addition, the silver ion release mechanism of the water purification treatment unit 10 according to the present embodiment includes a coil-shaped member 12 and a mesh member 14, and the coil-shaped member 12 is hollow, and the mesh member 14 is Since it has a thin mesh shape (disk shape), when removing chlorine from tap water, compared to the case where a filter medium is interposed, the water flow of tap water is hardly interrupted. There is no reduction.
For this reason, it is possible to provide a comfortable shower head S (water discharge device) that is easy to use and does not decrease the momentum of the tap water flowing out of the water outlet 6.

  Further, as shown in FIGS. 4A to 4C, in this embodiment, the magnetic processing mechanism of the magnetic processing unit 20 includes a magnetic generation unit 22 in which a permanent magnet 22a is incorporated, and the magnetic generation unit 22. A magnetic body portion 24 disposed opposite to the magnetic body portion 24 and an annular flow passage 26 having a predetermined width through which tap water can flow are formed between the magnetic generation portion 22 and the magnetic body portion 24. A uniform magnetic force acts on the entire flow path 26 between the magnetism generating section 22 and the magnetic body section 24. When tap water flows in the flow path 26, the tap water The magnetic force acts on the whole.

  In this case, in order to increase the magnetic processing capability of the magnetic generator 22 for tap water (in order to generate the maximum magnetic force), the magnet generator 22 includes a plurality of permanent magnets 22a, which are at least adjacent to each other. The pair of matching permanent magnets 22a are arranged so that the same poles face each other. In the present embodiment, the permanent magnet 22a has a disk shape, and a cylindrical magnetism generator 22 is configured by laminating seven of the disk-shaped permanent magnets 22a as an example. .

  FIG. 4B shows an example of an array of seven permanent magnets 22a constituting such a cylindrical magnetism generator 22, and one magnetic body is provided between each pair of adjacent permanent magnets 22a. 22b is interposed, and the magnetic poles of the permanent magnets 22a on both sides of the magnetic body 22b are opposed to each other with the same polarity (N pole or S pole). Note that the number and arrangement of the permanent magnets 22a and the magnetic bodies 22b are not limited to the above-described combinations, and can be any number or arrangement according to the purpose of use or use environment. One magnetic body 22b may be interposed at the intermediate position.

  Further, as an example, it is preferable to apply a neodymium magnet to the permanent magnet 22a incorporated in the magnetism generating unit 22. A neodymium magnet is the most powerful magnet among commercially available permanent magnets, and has a magnetic force 10 times or more that of a normal ferrite magnet and 6 to 7 times or more that of an alnico magnet. As a result, the magnetic generator 22 using a neodymium magnet can generate a strong magnetic force of about 7000 gauss. However, neodymium magnets are vulnerable to heat, and the magnetic force may decrease when a certain temperature is exceeded. Considering such a case, a heat-resistant neodymium magnet may be applied. For example, a ferrite magnet (Ba ferrite, Sr ferrite), an alnico magnet, or a samarium magnet may be applied as the other permanent magnet 22a.

  In addition, when a neodymium magnet is applied as the permanent magnet 22a of the magnetism generating unit 22, it is preferable to provide a waterproof cover 28 for waterproofing the permanent magnet 22a. In this case, the waterproof cover 28 is provided so as to cover the plurality of permanent magnets 22a and the magnetic body 22b and to be in an airtight and liquidtight state. Moreover, as long as the material of the waterproof cover 28 can waterproof the permanent magnet 22a, any material (for example, resin, rubber, etc.) can be applied, but the magnetic force of the permanent magnet 22a is reduced. It is necessary to form it with a non-magnetic material free from any material.

  Moreover, as a material of the magnetic body 22b interposed between a pair of adjacent permanent magnets 22a, for example, 400 series (403, 405, 410, 430, 434) stainless steel (SUS) can be applied. Stainless steel 430 is particularly preferable.

  Further, as shown in FIG. 4B, the magnetic body portion 24 of the magnetic processing mechanism is concentrically opposed along the magnetic generation portion 22 as described above. Specifically, the magnetic body portion 24 has a hollow cylindrical shape, and is concentrically opposed so as to cover the entire outer peripheral surface of the cylindrical magnetism generating portion 22. In this case, it is preferable to position the magnetic body portion 24 with respect to the magnetism generating portion 22 so that the width W of the flow path 26 has a constant dimension value. As a result, a uniform magnetic force can be applied to the tap water over the entire flow path 26. In the present embodiment, as an example, the magnetic body portion 24 is formed so that its outer diameter is substantially the same as the maximum diameter of the coiled member 12.

  The arrangement of the magnetic generator 22 and the magnetic body 24 is not limited to the above-described arrangement. For example, contrary to the above-described arrangement, the magnetic generation is performed so as to cover the entire outer peripheral surface of the magnetic body 24. The portions 22 may be concentrically opposed to each other. In this case, each permanent magnet 22a and magnetic body 22b of the magnetism generator 22 are formed in an annular shape.

  In the magnetic treatment mechanism, if the width W of the flow path 26 is reduced, the magnetic treatment effect on tap water flowing through the flow path 26 can be improved. However, if the flow rate is too small, the flow efficiency of tap water decreases, so the width W of the flow path 26 is preferably set in the range of 2 mm to 9 mm (particularly 2 mm).

  Further, the magnetism generating part 22 and the magnetic body part 24 are positioned and fixed in the water flow part 4 by the support plate 30 and the support plate 32, and the support plate 30 is configured so as to be magnetized. The support plate 32 is disposed at the other end (upper side of FIG. 4B). The support plate 30 has a plurality of openings 30 a for allowing tap water to flow into the flow path 26, and the support plate 32 has a plurality of openings 32 a for allowing tap water to flow out of the flow path 26. In this case, the support plate 30 and the opening 30a may have the same configuration as, for example, the support plate 32 and the opening 32a shown in FIG.

  In the present embodiment, as shown in FIG. 1B, as an example, the magnetic processing mechanism (the magnetic generation unit 22 and the magnetic body unit 24) of the magnetic processing unit 20 is connected to the water flow unit 4 by the support plates 30 and 32. It is positioned and fixed to the uppermost part (the water discharge part 6 side of the coil-like member 12 and the mesh-like member 14). In addition, arrangement | positioning of a magnetic processing mechanism is not limited to the arrangement | positioning mentioned above, For example, the lowest part in the water flow part 4 (The water-inflow part 6 side rather than the coil-shaped member 12 and the mesh-shaped member 14), or an intermediate part (For example, between the coil-like member 12 and the mesh-like member 14) may be arranged.

  According to such a configuration, when tap water taken from the water inlet 2 of the shower head S passes through the water passage 4 toward the water outlet 6, the tap water is introduced into the flow path 26 from the opening 32 a of the support plate 32. The magnetic treatment is performed by receiving the magnetic force action (magnetic field or magnetic field) generated between the magnetic generating part 22 and the magnetic part 24 while flowing while staying here. Then, the tap water (magnetic water) that has flowed through the flow path 26 and has been subjected to magnetic treatment flows out of the flow path 26 from the opening 30a of the support plate 30 and passes through the water flow section 4. When the water flows out from the water discharge section 6, negative ions are generated (released) in the air.

  Magnetic treatment is a treatment method using a phenomenon (electromagnetic induction phenomenon) in which a current flows through a conductor (for example, tap water) in a magnetic field, and when magnetically treating tap water, The condition is that tap water passes at right angles to the magnetic field (magnetic field). This is because magnetic processing is established by the magnetic field, current, and water flow (force) acting at right angles to each other according to Fleming's right-hand rule.

  As described above, according to the magnetic processing mechanism of the magnetic processing unit 20 of the present embodiment, the water is taken in from the water inlet 2 of the shower head S, passes through the water inlet 4 toward the water outlet 6, and from the water outlet 6. Regardless of the water pressure or amount of tap water until it is discharged, it can continue to generate negative ions stably from the tap water while using the shower head S. For example, it reduces fatigue and exhibits healing effects. A comfortable shower head S (water discharge device) can be provided.

  Here, the result of verifying the negative ion generation capability of the magnetic processing mechanism (the magnetic generation unit 22 and the magnetic body unit 24) of the magnetic processing unit 20 according to the present embodiment will be described below. In this case, in an environment of a room temperature of 23 ° C. and a humidity of 55%, 1 L of water is taken in from the water inlet part 2 of the shower head S, passed through the water passing part 4 and discharged from the water outlet part 6, and the discharged tap water. The number of negative ions generated from the above was measured, and the verification was repeated 5 times. As a result, in each verification, 120,000 to 80,000 negative ions are generated, and the magnetic processing mechanism (the magnetic generation unit 22 and the magnetic body unit 24) of the present embodiment has an excellent negative ion generation capability. It was verified.

  In the present embodiment, the tap water passing through the water passage 4 in the direction of the water outlet 6 is a coil in the water passage 4 before the magnetic action is applied by the magnetic processing mechanism of the magnetic processor 20. It passes through the shaped member 12. Since the coil-shaped member 12 has a spiral shape whose diameter changes from one end to the other, tap water passing through the coil-shaped member 12 follows the spiral of the coil-shaped member 12. Turn. By rotating the tap water in this way, positive ions in the water gather at the central part of the swirling flow, and negative ions gather at the outer part of the swirling flow (the cluster structure of water molecules is subdivided). Therefore, the tap water that has passed through the coiled member 12 and has flowed into the magnetic processing unit 20 can be more effectively subjected to magnetic force, and more negative ions can be generated.

  Further, in the present embodiment, the water purification unit 10 has a photocatalytic reaction mechanism that removes chlorine in water by oxidizing and decomposing water using a photocatalyst in addition to the silver ion releasing mechanism described above. In this case, as shown in FIG. 1 (a), the photocatalytic reaction mechanism includes a daylighting unit 16 that takes outside light into the water discharge device (shower head S), and at least part of the daylighting unit 16 is transparent. A photocatalyst including at least brookite-type titanium oxide is provided inside the photocatalyst. And when the said photocatalyst receives external light and carries out a photocatalytic reaction, water contacts with the said photocatalyst and is oxidatively decomposed. The brookite-type titanium oxide means orthorhombic titanium oxide whose crystal structure is inclined obliquely.

In the present embodiment, as an example, the photocatalytic reaction mechanism is configured such that the daylighting portion 16 is configured as an outer case 4a of the water passing portion 4 of the shower head S, and the daylighting portion 16 is the water passing portion 4 of the shower head S. The entire outer case 4a is colorless and transparent or colored and transparent. As a result, the photocatalytic reaction mechanism takes in external light from the entire outer case 4 a of the water passing portion 4 of the shower head S into the water passing portion 4.
The material of the outer case 4a (lighting unit 16) of the water flow unit 4 is not particularly limited as long as it is a translucent material that can take in external light into the water flow unit 4. For example, polycarbonate, etc. Acrylic resin can be applied.

  Moreover, the outer case 4a (lighting part 16) of the water flow part 4 has a shape that makes it easier to take outside light into the water flow part 4. FIG. 1 (a) and FIG. An example is shown. In this embodiment, the outer case 4a (lighting part 16) of the water flow part 4 has a cylindrical shape whose diameter gradually increases from the water inlet part 2 side to the water outlet part 6 side as an example, and the outer periphery of the cross section. The shape is a regular decagon and the inner peripheral shape of the cross section is a star having 12 vertices. Thereby, the surface area of the outer peripheral surface of the outer case 4a (lighting part 16) of the water flow part 4 and an internal peripheral surface can be enlarged, and external light can be taken in in the water part 4 more efficiently. Become.

  In addition, the shape of the outer case 4a (lighting part 16) of the water flow part 4 is not limited to the above-mentioned shape, and if it is a shape in which external light can be easily taken in into the water flow part 4, a use purpose and use Any shape can be designed according to the environment. For example, the outer peripheral shape of the cross section of the outer case 4a (lighting portion 16) of the water flow portion 4 is formed to form a star shape having a large number of vertices, and the inner peripheral shape of the cross section is formed to be a regular polygon. The outer peripheral shape and the inner peripheral shape of the cross section may be formed so as to form a star shape having a large number of vertices. Moreover, you may form the outer side shape of the outer side case 4a (lighting part 16) of the water flow part 4 in a wave shape.

Further, the entire surface of the magnetic processing unit 20 (the surface in contact with the tap water passing through the water passage 4) is also subjected to a coating process to form a brookite-type titanium dioxide thin film 18b (FIG. 1 (b) and FIG. 4 (a)). Then, the photocatalytic reaction can be activated by irradiating the thin films 18a and 18b with ultraviolet rays contained in the external light taken from the entire outer case 4a (lighting unit 16) of the water flow unit 4.

  The coating treatment for forming a thin film of a photocatalyst (for example, brookite type titanium dioxide) may be performed on a silver ion release mechanism (for example, the coiled member 12 or the mesh member 14). In this case, it is preferable to perform a coating treatment so that the formed thin film does not affect the release of silver ions from the silver ion release mechanism. Thus, the photocatalytic reaction can be further activated by forming a thin film of a photocatalyst (for example, brookite-type titanium dioxide) on the silver ion release mechanism (for example, the coiled member 12 or the mesh member 14). It becomes possible.

  In this embodiment, the inner surface of the outer case 4a of the water passing portion 4 and the surface of the magnetic treatment portion 20 on which the brookite-type titanium dioxide thin films 18a and 18b are formed are tap water passing through the water passing portion 4. When the thin film 18a, 18b (photocatalyst) is irradiated with ultraviolet rays and the photocatalytic reaction is activated, the tap water comes into contact with the thin film 18a, 18b (photocatalyst) and is oxidatively decomposed. Chlorine can be removed from tap water.

  Thus, according to the photocatalytic reaction mechanism of the water purification treatment unit 10 of the present embodiment, the photocatalytic reaction can be activated semi-permanently by irradiating with ultraviolet rays. As described above, for example, a filter medium (for example, activated carbon The water purification ability (residual chlorine removal ability) does not decrease unlike chlorine removal using calcium sulfite), and a constant chlorine removal ability can be exhibited over a long period of time. As a result, there is no need for regular maintenance, there is no running cost, and the comfort is easy to use (for example, the hair after washing is smooth even without rinsing) Appliances) can be provided.

  Here, the result of verifying the water purification ability (residual chlorine removal ability) of the photocatalytic reaction mechanism of the water purification treatment unit 10 according to the present embodiment will be described below. In this case, in an environment of room temperature 23 ° C. and humidity 55%, 1 L of water (free residual chlorine concentration 1 ppm) is taken in from the water inlet 2 of the shower head S, passed through the water passage 4 and flows out from the water outlet 6. The free residual chlorine of the spilled tap water was measured, and the verification was repeated five times. As a result, the average free residual chlorine concentration of the outflow tap water at each time was 0.92 ppm.

  Therefore, it is verified that the photocatalytic reaction mechanism of this embodiment has a water purification ability (residual chlorine removal ability) that reduces free residual chlorine by 8%, and is combined with the water purification ability (residual chlorine removal ability) of the silver ion release mechanism described above. Thus, according to the shower head S (equipment for water discharge) of the present embodiment, it was verified that it has a water purification ability (residual chlorine removal ability) that reduces free residual chlorine in tap water by 60%.
