　上述の技術においては、普通の水道水を容器に投入するだけでは溶出する銀金属イオンの濃度は極めて低い。これに対して、希塩酸などの酸を加えることによって、金属イオンの濃度を高くすることができるが、使用者において、使用する度に希塩酸などの酸を加えることは煩雑である。 In the above technology, the concentration of silver metal ions eluted by simply pouring ordinary tap water into a container is extremely low. On the other hand, the concentration of metal ions can be increased by adding an acid such as dilute hydrochloric acid, but it is complicated for the user to add an acid such as dilute hydrochloric acid each time the product is used.
　本発明は、上記を踏まえて、容易に金属イオン水を生成することができる金属イオン水生成容器を提供するものである。 Based on the above, the present invention provides a metal ionized water generation container capable of easily generating metal ionized water.
　第一の発明は、水を格納する容器本体と、前記容器本体内に格納された前記水と接することができ、細菌を低減する効果を有する金属である第一の金属の微粒子が分散した第一の樹脂によって形成される主部材と、前記容器本体の内側に配置され、前記容器本体に格納された前記水と接することによって、前記水に水素イオンを発生させる性質を有する第二の金属を含む部材で構成される補助部材と、を有する金属イオン水生成容器である。 In the first invention, the container body for storing water and the fine particles of the first metal, which is a metal capable of contacting the water stored in the container body and having an effect of reducing bacteria, are dispersed. A second metal having a property of generating hydrogen ions in the water by contacting the main member formed of one resin and the water disposed inside the container body and stored in the container body. It is a metal ionized water generation container having an auxiliary member composed of a member including the member.
　希硫酸やクエン酸などの酸を水に加えることによって、水中に配置した金属銅などの金属からの金属イオンの溶出が促進される事象は知られている。本発明の発明者は、その事象の原因として、水中の水素イオンが作用していることに着眼した。そして、水中に水素イオンを発生させる補助部材を配置することによって、電池などの外部からの電源を要する電気分解を用いることなく、水中に配置した金属銅からの金属イオンの溶出を促進させる技術思想に想到した。第一の発明の構成によれば、主部材は、細菌を低減する効果を有する金属である第一の金属の微粒子が分散した第一の樹脂によって形成される。そして、補助部材は、水に水素イオンを発生させる性質を有する第二の金属を含む部材で構成される。したがって、容器本体に水を格納すると、補助部材が水中に水素イオンを発生させ、その水素イオンが主部材からの金属イオンの溶出を促進する。これにより、使用者は、希硫酸やクエン酸などの酸を使用することなく、容器本体に水を入れるだけで容易に金属イオン水を生成することができる。 It is known that adding an acid such as dilute sulfuric acid or citric acid to water promotes the elution of metal ions from a metal such as metallic copper placed in water. The inventor of the present invention has focused on the action of hydrogen ions in water as the cause of the event. Then, by arranging an auxiliary member that generates hydrogen ions in water, a technical idea that promotes elution of metal ions from metallic copper arranged in water without using electrolysis that requires an external power source such as a battery. I came up with. According to the configuration of the first invention, the main member is formed of a first resin in which fine particles of the first metal, which is a metal having an effect of reducing bacteria, are dispersed. The auxiliary member is composed of a member containing a second metal having a property of generating hydrogen ions in water. Therefore, when water is stored in the container body, the auxiliary member generates hydrogen ions in the water, and the hydrogen ions promote the elution of metal ions from the main member. As a result, the user can easily generate metal ionized water simply by putting water in the container body without using an acid such as dilute sulfuric acid or citric acid.
　第二の発明は、第一の発明の構成において、前記補助部材は、前記第二の金属の微粒子が第二の樹脂に分散されて形成される、金属イオン水生成容器である。 The second invention is, in the configuration of the first invention, the auxiliary member is a metal ionized water generation container formed by dispersing fine particles of the second metal in a second resin.
　第二の発明の構成によれば、補助部材は、第二の金属の微粒子が第二の樹脂に分散されて形成されるから、構造の自由度が大きい。このため、金属イオン水生成容器の部品を補助部品とすることができる。例えば、容器本体の上部にポンプを配置する場合に、ポンプに水を吸い上げるための筒状部材を補助部材として構成することができる。あるいは、補助部材を水と等しい比重の部材として構成し、容器本体に入れられた水の中を浮遊する浮遊部材として構成することができる。 According to the configuration of the second invention, the auxiliary member is formed by dispersing fine particles of the second metal in the second resin, so that the degree of freedom of the structure is large. Therefore, the parts of the metal ionized water generation container can be used as auxiliary parts. For example, when the pump is arranged on the upper part of the container body, a tubular member for sucking water into the pump can be configured as an auxiliary member. Alternatively, the auxiliary member can be configured as a member having a specific gravity equal to that of water, and can be configured as a floating member that floats in the water contained in the container body.

It is a metal ionized water generation container.
　本発明の発明者は、主部材に含まれる第一の金属の量が同一であっても、樹脂中にセラミックの微粒子を分散させることによって、銅イオンの溶出量が増加する現象を見出した。この点、第三の発明の構成によれば、主部材は、第一の樹脂に、第一の金属の微粒子とセラミックの微粒子が分散して形成されるから、効率良くより高濃度の金属イオン水を生成することができる。 The inventor of the present invention has found a phenomenon in which the elution amount of copper ions increases by dispersing ceramic fine particles in a resin even if the amount of the first metal contained in the main member is the same. In this regard, according to the configuration of the third invention, since the main member is formed by dispersing the fine particles of the first metal and the fine particles of the ceramic in the first resin, the metal ions having a higher concentration are efficiently formed. Can produce water.
　第四の発明は、第二の発明の構成において、前記主部材は、前記第一の樹脂に、前記第一の金属の微粒子とセラミックの微粒子が分散して形成され、前記補助部材は、前記第二の樹脂に、前記第二の金属の微粒子とセラミックの微粒子が分散して形成される、金属イオン水生成容器である。 In the fourth aspect of the invention, in the configuration of the second invention, the main member is formed by dispersing the first metal fine particles and the ceramic fine particles in the first resin, and the auxiliary member is the auxiliary member. It is a metal ionized water generation container formed by dispersing the fine particles of the second metal and the fine particles of ceramic in the second resin.
　第四の発明の構成によれば、主部材は、第一の樹脂に、第一の金属の微粒子とセラミックの微粒子が分散して形成され、補助部材は、第二の樹脂に、第二の金属の微粒子とセラミックの微粒子が分散して形成されるから、一層効率良くより高濃度の金属イオン水を生成することができる。 According to the configuration of the fourth invention, the main member is formed by dispersing the fine particles of the first metal and the fine particles of ceramic in the first resin, and the auxiliary member is formed in the second resin by the second. Since the metal fine particles and the ceramic fine particles are dispersed and formed, it is possible to more efficiently generate high-concentration metal ionized water.

It is a metal ionized water generation container that is formed.
　第五の発明の構成によれば、容器本体の内面が凹凸のない曲面または平面である場合に比べて、内面が水と接する面積を大きく構成することができるから、より一層有効に微粒子による細菌低減効果を活用することができる。 According to the configuration of the fifth invention, the area where the inner surface of the container body is in contact with water can be made larger than that of the case where the inner surface of the container body is a curved surface or a flat surface without unevenness. The reduction effect can be utilized.

　図６に示すように、容器本体２に水６０を格納すると、水６０は吸引チューブ６と接する。この状態で、吸引チューブ６を形成する二酸化チタンの微粒子４０に光（紫外線）が当たると、二酸化チタンから電子ｅが発生する。続いて、図７に示すように、電子ｅの作用によって、水６０から水素イオンＨ＋が発生する。続いて、図８に示すように、水素イオンＨ＋によって、容器本体２を形成する銅の微粒子３０から銅イオンＣｕ２＋の溶出が促進される。これにより、水６０は銅イオンを含む銅イオン水６２となる。このように、容器本体２に水を入れるだけで、外部の電源を使用する電気分解を利用することなく、容易に銅イオン水が生成される。上記の現象は、本発明の発明者による実験で確認されている。 As shown in FIG. 6, when the water 60 is stored in the container body 2, the water 60 comes into contact with the suction tube 6. In this state, when the fine particles 40 of titanium dioxide forming the suction tube 6 are exposed to light (ultraviolet rays), electrons e are generated from the titanium dioxide. Subsequently, as shown in FIG. 7, hydrogen ion H + is generated from the water 60 by the action of the electron e. Subsequently, as shown in FIG. 8, hydrogen ion H + promotes elution of copper ion Cu 2+ from the copper fine particles 30 forming the container body 2. As a result, the water 60 becomes copper ion water 62 containing copper ions. In this way, copper ion water can be easily generated by simply putting water in the container body 2 without using electrolysis using an external power source. The above phenomenon has been confirmed by experiments by the inventor of the present invention.
　本発明の発明者は、容器本体２に水を入れ、二酸化チタンを含む樹脂で形成した吸引チューブ６を入れた場合に、容器本体２に水だけを入れた場合に比べて、銅イオンの溶出量が大幅に増加する現象を確認した。図９は、当該確認結果を踏まえて、容器本体２に吸引チューブ６を配置せずに水だけを入れた場合と、容器本体に吸引チューブ６を配置して水を入れた場合（以下、「本実施形態」という。）における、銅イオンの発生状況の対比を示す。吸引チューブ６における二酸化チタンの重量比は６０重量％である。容器本体２における銅の微粒子３０の重量比は６０重量％である。図９は、室温において、２４時間ごとの銅イオン濃度の推移を示す。 The inventor of the present invention puts water in the container body 2, and when a suction tube 6 made of a resin containing titanium dioxide is put in, copper ions are eluted as compared with the case where only water is put in the container body 2. We confirmed the phenomenon that the amount increased significantly. FIG. 9 shows a case where only water is put in the container body 2 without arranging the suction tube 6 and a case where the suction tube 6 is placed in the container body 2 and water is put in based on the confirmation result. The comparison of the generation state of the copper ion in "the present embodiment") is shown. The weight ratio of titanium dioxide in the suction tube 6 is 60% by weight. The weight ratio of the copper fine particles 30 in the container body 2 is 60% by weight. FIG. 9 shows the transition of the copper ion concentration every 24 hours at room temperature.
　図９に示すように、容器本体２に水を入れただけの場合には、銅イオンの溶出の程度は低く、１２０日経過時において、２０ｐｐｍ未満である。これに対して、本実施形態の場合には、１０日経過時において、３０ｐｐｍを超えている。このように、吸引チューブ６の作用によって、容器本体２からの銅イオンの溶出が大幅に促進される。なお、本実施形態とは異なり、吸引チューブ６において、多数の微粒子４０のうち、少なくとも一部の微粒子４０が、樹脂８に覆われず、樹脂８から露出するように構成することによって、一層効果的に二酸化チタンから電子を発生させることができる。また、本実施形態とは異なり、容器本体２を上部（例えば、上下方向における上部の４分１）と下部（例えば、上下方向における下部の４分３）で構成し、上部は光透過性を有する樹脂に微粒子３０を混入させずに光透過性に優れる光透過部分（光導入部）として構成し、下部を本実施形態と同様に微粒子３０を混入させる構成としてもよい。 As shown in FIG. 9, when only water is put into the container body 2, the degree of elution of copper ions is low, and it is less than 20 ppm after 120 days. On the other hand, in the case of this embodiment, it exceeds 30 ppm after 10 days have passed. As described above, the action of the suction tube 6 significantly promotes the elution of copper ions from the container body 2. In addition, unlike the present embodiment, the suction tube 6 is further effective by being configured such that at least a part of the fine particles 40 out of a large number of fine particles 40 is not covered with the resin 8 and is exposed from the resin 8. Electrons can be generated from titanium dioxide. Further, unlike the present embodiment, the container body 2 is composed of an upper part (for example, an upper quarter in the vertical direction) and a lower part (for example, a lower quarter in the vertical direction), and the upper part has light transmission. The resin may be configured as a light transmitting portion (light introducing portion) having excellent light transmission without mixing the fine particles 30, and the lower portion may be configured to mix the fine particles 30 as in the present embodiment.
　図１０は、容器１００の使用例を示す図である。例えば、家屋２００の出入り口に玄関マット２０２が配置されている。母親２０４が、容器１００によって生成された銅イオン水６２を玄関マット２０２に吹き付けてしみ込ませておく。外出から帰った子供２０６や犬２０８が、家屋２００に入る前に玄関マット２０２を踏んで通過すると、玄関マット２０２にしみ込んだ銅イオン水６２に含まれる銅イオンの効果によって、子供２０６の靴の底部や犬の足についた細菌を低減させることができる。 FIG. 10 is a diagram showing a usage example of the container 100. For example, the entrance mat 202 is arranged at the entrance / exit of the house 200. The mother 204 sprays the copper ionized water 62 generated by the container 100 onto the entrance mat 202 and soaks it. When a child 206 or a dog 208 returning from going out steps on the entrance mat 202 before entering the house 200, the effect of the copper ions contained in the copper ion water 62 soaked into the entrance mat 202 causes the shoes of the child 206 to pass. It can reduce bacteria on the bottom and dog's feet.
＜第二の実施形態＞
　次に、図１１及び図１２を参照して、第二の実施形態について説明する。第一の実施形態と共通する事項は説明を省略し、異なる部分を中心に説明する。 <Second embodiment>
Next, a second embodiment will be described with reference to FIGS. 11 and 12. Items common to the first embodiment will be omitted, and different parts will be mainly described.
　図１１に示すように、第二の実施形態の容器本体２Ａは、樹脂４に銅の微粒子３０とセラミックの微粒子５０が分散して形成されている。セラミックは、例えば、アルミナや炭化ケイ素（ＳｉＣ）である。また、セラミックは、多孔質セラミックが望ましい。 As shown in FIG. 11, the container body 2A of the second embodiment is formed by dispersing copper fine particles 30 and ceramic fine particles 50 in a resin 4. The ceramic is, for example, alumina or silicon carbide (SiC). Further, the ceramic is preferably a porous ceramic.
　図１２は、容器本体２Ａの構成として、樹脂４に銅の微粒子３０のみを分散させた場合と、銅の微粒子３０とセラミックの微粒子５０を分散させた場合において、容器本体２Ａに水をいれた場合の銅イオンの溶出の程度の対比を示す。容器本体２Ａには、クエン酸を０．０１重量％含むクエン酸水を入れた。容器本体２Ａにおいて樹脂４に銅の微粒子３０のみを分散させた場合の構成(以下、「構成１」という。)は、重量比で、銅の微粒子：樹脂＝１０：９０である。容器本体２Ａにおいて樹脂４に銅の微粒子３０とセラミックの微粒子５０を分散させた場合の構成（以下、「構成２」という。）は、重量比で、銅の微粒子：セラミックの微粒子：樹脂＝１０：５０：４０である。すなわち、構成２は、構成１における樹脂の一部をセラミックの微粒子に置き換えた構成である。
１０日経過時において、第一の構成の場合には、銅イオンは２．５ｐｐｍ以下であった。これに対して、構成２の場合には、１０日経過時において、約９．０ｐｐｍであった。このことから、容器本体２Ａにおける銅の微粒子３０の重量が変わらなくても、セラミックの微粒子５０を加えることによって、銅イオンの溶出は大幅に促進されることがわかる。 In FIG. 12, as the configuration of the container body 2A, water is poured into the container body 2A in the case where only the copper fine particles 30 are dispersed in the resin 4 and the case where the copper fine particles 30 and the ceramic fine particles 50 are dispersed. The comparison of the degree of elution of copper ion in the case is shown. In the container body 2A, citric acid water containing 0.01% by weight of citric acid was put. In the container body 2A, when only the copper fine particles 30 are dispersed in the resin 4, the configuration (hereinafter referred to as “configuration 1”) is a copper fine particle: resin = 10: 90 in terms of weight ratio. In the container body 2A, when the copper fine particles 30 and the ceramic fine particles 50 are dispersed in the resin 4, the configuration (hereinafter referred to as “configuration 2”) is a weight ratio of copper fine particles: ceramic fine particles: resin = 10. : 50:40. That is, the configuration 2 is a configuration in which a part of the resin in the configuration 1 is replaced with ceramic fine particles.
At the lapse of 10 days, in the case of the first configuration, the copper ion was 2.5 ppm or less. On the other hand, in the case of Configuration 2, it was about 9.0 ppm after 10 days. From this, it can be seen that even if the weight of the copper fine particles 30 in the container body 2A does not change, the elution of copper ions is significantly promoted by adding the ceramic fine particles 50.
　樹脂４に銅の微粒子３０とセラミックの微粒子５０を分散させることによって、銅イオンの溶出が大幅に促進される理由の一つは、銅イオンが樹脂４を通過する抵抗よりも、セラミックの微粒子５０を通過する抵抗、あるいは、セラミックの微粒子５０の表面を通過する抵抗の方が小さいことによると考えられる。 One of the reasons why the elution of copper ions is greatly promoted by dispersing the copper fine particles 30 and the ceramic fine particles 50 in the resin 4 is that the ceramic fine particles 50 are more than the resistance of the copper ions to pass through the resin 4. It is considered that the resistance through the ceramic particles 50 or the resistance through the surface of the ceramic fine particles 50 is smaller.
＜第三の実施形態＞
　次に、図１３を参照して、第三の実施形態について説明する。第二の実施形態と共通する事項は説明を省略し、異なる部分を中心に説明する。 <Third embodiment>
Next, a third embodiment will be described with reference to FIG. The matters common to the second embodiment will be omitted, and the different parts will be mainly described.
　図１３に示すように、第三の実施形態の吸引チューブ６Ａは、樹脂８に二酸化チタンの微粒子４０とセラミックの微粒子５０が分散して形成されている。 As shown in FIG. 13, the suction tube 6A of the third embodiment is formed by dispersing titanium dioxide fine particles 40 and ceramic fine particles 50 in the resin 8.
　樹脂８に二酸化チタンの微粒子４０に加えて、セラミックの微粒子５０を分散させることによって、第二の実施形態における銅イオンの溶出の促進の効果と同様に、二酸化チタンからの電子の発生を促進することができ、より一層効果的に銅イオン水を生成することができる。 By dispersing the ceramic fine particles 50 in addition to the titanium dioxide fine particles 40 in the resin 8, the generation of electrons from the titanium dioxide is promoted as in the effect of promoting the elution of copper ions in the second embodiment. It is possible to generate copper ionized water even more effectively.
＜第四の実施形態＞
　次に、図１４を参照して、第四の実施形態について説明する。第二の実施形態及び第三の実施形態と共通する事項は説明を省略し、異なる部分を中心に説明する。 <Fourth Embodiment>
Next, a fourth embodiment will be described with reference to FIG. The matters common to the second embodiment and the third embodiment will be omitted, and different parts will be mainly described.
　図１４に示すように、第四の実施形態の容器本体２Ｂの内面２ａは、複数の凸部及び凹部を有する凹凸面として形成されている。これにより、容器本体２Ｂに水をいれたときに、水と接する内面２ａの面積が大きくなり、より効果的に銅イオンを溶出することができる。 As shown in FIG. 14, the inner surface 2a of the container body 2B of the fourth embodiment is formed as an uneven surface having a plurality of convex portions and concave portions. As a result, when water is poured into the container body 2B, the area of the inner surface 2a in contact with the water becomes large, and copper ions can be more effectively eluted.
　＜第五の実施形態＞
　次に、図１５を参照して、第五の実施形態について説明する。第四の実施形態と共通する事項は説明を省略し、異なる部分を中心に説明する。 <Fifth Embodiment>
Next, a fifth embodiment will be described with reference to FIG. The matters common to the fourth embodiment will be omitted, and the different parts will be mainly described.
　図１５に示すように、第五の実施形態の容器本体２Ｃの内面２ａは、複数の凸部及び凹部を有する凹凸面として形成されている。そして、複数の銅の微粒子３０のうち、一部は、内面２ａの外部に露出している。これにより、容器本体２Ｃに水を入れたときに、微粒子３０が直接的に水と接し、より効果的に銅イオンを溶出することができる。 As shown in FIG. 15, the inner surface 2a of the container body 2C of the fifth embodiment is formed as an uneven surface having a plurality of convex portions and concave portions. Then, a part of the plurality of copper fine particles 30 is exposed to the outside of the inner surface 2a. As a result, when water is put into the container body 2C, the fine particles 30 come into direct contact with the water, and copper ions can be more effectively eluted.
　＜第六の実施形態＞
　次に、図１６乃至図１８を参照して、第六の実施形態について説明する。第一の実施形態と共通する事項は説明を省略し、異なる部分を中心に説明する。 <Sixth Embodiment>
Next, the sixth embodiment will be described with reference to FIGS. 16 to 18. Items common to the first embodiment will be omitted, and different parts will be mainly described.
　図１６に示すように、第六の実施形態の容器本体２Ｄの内部には、吸引チューブ６、浮遊部材２０Ａ，２０Ｂ及び２０Ｃが配置されている。吸引チューブ６は、第一の実施形態において説明したように、二酸化チタンの微粒子が樹脂に分散して形成されている。浮遊部材２０Ａ，２０Ｂ及び２０Ｃは、第一の実施形態の容器本体２と同様に、銅の微粒子３０が樹脂４に分散することによって形成される。浮遊部材２０Ａ，２０Ｂ及び２０Ｃは、主部材の一例である。容器本体２Ｄは、光透過性を有する樹脂のみで形成されており、銅の微粒子３０は含まれていない。外部の光は、容器本体２Ｄを透過して容器本体２Ｄの内部に導入される。容器本体２Ｄ自体が、光導入部の一例である。 As shown in FIG. 16, a suction tube 6, floating members 20A, 20B and 20C are arranged inside the container body 2D of the sixth embodiment. As described in the first embodiment, the suction tube 6 is formed by dispersing titanium dioxide fine particles in the resin. The floating members 20A, 20B and 20C are formed by dispersing copper fine particles 30 in the resin 4, as in the container body 2 of the first embodiment. The floating members 20A, 20B and 20C are examples of main members. The container body 2D is made of only a light-transmitting resin, and does not contain copper fine particles 30. External light passes through the container body 2D and is introduced into the container body 2D. The container body 2D itself is an example of the light introduction unit.
　図１６及び図１７に示すように、浮遊部材２０Ａ等は、それぞれ、星形、ハート型、及び、球形に構成されているが、その形態はこれに限定されず、さまざまな形態を採用することが可能である。 As shown in FIGS. 16 and 17, the floating member 20A and the like are configured to have a star shape, a heart shape, and a spherical shape, respectively, but the form thereof is not limited to this, and various forms may be adopted. Is possible.
　浮遊部材２０Ａ等の比重は、水の比重と実質的に等しく構成されている。このため、図１８に示すように、容器本体２に水６０が入れられると、浮遊部材２０Ａ等は水中を浮遊する。容器本体２に水６０がいれられた状態において、浮遊部材２０Ａ等は、容器本体２の内面を接することなく水６０中を浮遊する。浮遊部材２０Ａ等の比重の調整は、浮遊部材２０Ａ等に含まれる銅の微粒子３０の重量を所定の重量にし、所望の比重を有する樹脂を使用することによって行う。例えば、比重が小さな樹脂を使用すれば、微粒子３０の重量が変わらなくても、浮遊部材２０Ａ等の比重は小さくなる。なお、本実施形態とは異なり、浮遊部材２０Ａ等の中心部を樹脂のみで構成し、浮遊部材２０Ａ等の外側の表面部を銅の微粒子３０を分散させた樹脂によって構成してもよい。なお、本実施形態とは異なり、浮遊部材２０Ａ等の外側の表面に、銅の微粒子３０が露出する構成としてもよい。 The specific gravity of the floating member 20A or the like is substantially equal to the specific gravity of water. Therefore, as shown in FIG. 18, when the water 60 is put into the container body 2, the floating member 20A and the like float in the water. In a state where the water 60 is put in the container body 2, the floating member 20A or the like floats in the water 60 without touching the inner surface of the container body 2. The specific gravity of the floating member 20A or the like is adjusted by setting the weight of the copper fine particles 30 contained in the floating member 20A or the like to a predetermined weight and using a resin having a desired specific gravity. For example, if a resin having a small specific gravity is used, the specific gravity of the floating member 20A or the like becomes small even if the weight of the fine particles 30 does not change. In addition, unlike this embodiment, the central portion of the floating member 20A or the like may be composed of only a resin, and the outer surface portion of the floating member 20A or the like may be composed of a resin in which copper fine particles 30 are dispersed. In addition, unlike the present embodiment, the copper fine particles 30 may be exposed on the outer surface of the floating member 20A or the like.
　外部からの光が容器本体２Ｄを透過し、吸引チューブ６に光が当たると、吸引チューブ６から電子が飛び出し、水６０から水素イオンを発生させ、浮遊部材２０Ａ等を構成する銅の微粒子３０からの銅イオンの溶出を促進する。 When light from the outside passes through the container body 2D and the light hits the suction tube 6, electrons are ejected from the suction tube 6 to generate hydrogen ions from the water 60, and the copper fine particles 30 constituting the floating member 20A and the like are used. Promotes the elution of copper ions.
＜変形例＞
　第六の実施形態とは異なり、吸引チューブ６を樹脂のみで構成し、浮遊部材２０Ａ等のうち、一部を二酸化チタンの微粒子４０を樹脂８に分散させて形成し、他を銅の微粒子３０を樹脂４に分散させて形成するようにしてもよい。例えば、浮遊部材２０Ａは、二酸化チタンの微粒子４０を樹脂８に分散させて形成し、浮遊部材２０Ｂ及び２０Ｃは、銅の微粒子３０を樹脂４に分散させて形成する。 <Modification example>
Unlike the sixth embodiment, the suction tube 6 is made of only resin, a part of the floating member 20A and the like is formed by dispersing titanium dioxide fine particles 40 in the resin 8, and the other is copper fine particles 30. May be dispersed in the resin 4 to form the resin 4. For example, the floating member 20A is formed by dispersing titanium dioxide fine particles 40 in the resin 8, and the floating members 20B and 20C are formed by dispersing copper fine particles 30 in the resin 4.
　＜第七の実施形態＞
　次に、図１９を参照して、第七の実施形態について説明する。第一の実施形態と共通する事項は説明を省略し、異なる部分を中心に説明する。 <Seventh Embodiment>
Next, a seventh embodiment will be described with reference to FIG. Items common to the first embodiment will be omitted, and different parts will be mainly described.
　第七の実施形態の容器本体２Ｅは、光透過性を有する樹脂のみで形成されている。外部の光は、容器本体２Ｅを透過して容器本体２Ｅの内部に導入される。容器本体２Ｅ自体が、光導入部の一例である。 The container body 2E of the seventh embodiment is formed only of a resin having light transmission. External light passes through the container body 2E and is introduced into the container body 2E. The container body 2E itself is an example of the light introduction unit.
　図１９に示すように、第六の実施形態の容器本体２Ｅの内部には、吸引チューブ６、及び、円板状部材１２が配置されている。吸引チューブ６は、第一の実施形態において説明したように、二酸化チタンの微粒子４０が樹脂８に分散して形成されている。円板状部材１２は、容器本体２Ｅの底部に固定されている。円板状部材１２は、第一の実施形態の容器本体２と同様に、銅の微粒子３０が樹脂４に分散することによって形成される。円板状部材１２は、主部材の一例である。 As shown in FIG. 19, a suction tube 6 and a disk-shaped member 12 are arranged inside the container body 2E of the sixth embodiment. As described in the first embodiment, the suction tube 6 is formed by dispersing titanium dioxide fine particles 40 in the resin 8. The disk-shaped member 12 is fixed to the bottom of the container body 2E. The disk-shaped member 12 is formed by dispersing copper fine particles 30 in the resin 4, as in the container body 2 of the first embodiment. The disk-shaped member 12 is an example of a main member.
　容器本体２Ｅに水６０を入れた状態において、外部からの光が容器本体２Ｅを透過し、吸引チューブ６に光が当たると、吸引チューブ６から電子が飛び出し、水６０から水素イオンを発生させ、円板状部材１２を構成する銅の微粒子３０からの銅イオンの溶出を促進する。 When water 60 is put in the container body 2E, light from the outside passes through the container body 2E, and when the light hits the suction tube 6, electrons are ejected from the suction tube 6 to generate hydrogen ions from the water 60. It promotes the elution of copper ions from the copper fine particles 30 constituting the disk-shaped member 12.
　なお、本発明の金属イオン水生成容器は、上記実施形態に限らず、本発明の要旨を逸脱しない範囲内において種々変更を加えることができる。また、各上記実施形態は、技術的に矛盾を生じない限り、適宜、組み合わせることができる。 The metal ionized water generation container of the present invention is not limited to the above embodiment, and various modifications can be made without departing from the gist of the present invention.
