Description
本発明は、無機化合物等を溶解する溶解装置、及び溶解した無機化合物等を浴槽等に供給する機能を備えた給湯装置に関するものである。 The present invention relates to a melting apparatus for dissolving an inorganic compound and the like, and a hot water supply apparatus having a function of supplying the dissolved inorganic compound and the like to a bathtub or the like.
従来この種の装置は、目的の成分を含む材料を電気分解にて水中に溶解させ、この溶解した水を目的とする回路へ供給している（例えば、特許文献１参照）。 Conventionally, this type of apparatus dissolves a material containing a target component in water by electrolysis, and supplies the dissolved water to a target circuit (for example, see Patent Document 1).
図９は、特許文献１に記載された従来の給湯装置を示すものである。図９に示すように、亜鉛陽極１と、陰極２と、ケーシング５と、直流電源９から構成されている。 FIG. 9 shows a conventional hot water supply apparatus described in Patent Document 1. As shown in FIG. As shown in FIG. 9, it is composed of a zinc anode 1, a cathode 2, a casing 5, and a DC power source 9.
しかしながら、前記従来の構成では、目的とする成分（亜鉛陽極１）の水への溶解方法は、電気分解の原理によるため、直流電源９と、回路を流れる水への漏電を防止するための絶縁回路（図示せず）が必要となる。従って、装置のサイズアップ、コストアップとともに、直流電源９においては電力を必要とするため消費電力量も増加する。 However, in the above-described conventional configuration, the method of dissolving the target component (zinc anode 1) in water is based on the principle of electrolysis, and therefore, the DC power source 9 and insulation for preventing leakage to water flowing in the circuit. A circuit (not shown) is required. Therefore, along with the increase in the size and cost of the apparatus, the DC power supply 9 requires power, so that the amount of power consumption increases.
本発明は、前記従来の課題を解決するもので、電気回路を必要とせず、コンパクトで運転コストが安価、かつ、使用性の高い無機化合物等を供給する溶解装置及びそれを備えた給湯装置を提供することを目的とする。 The present invention solves the above-described conventional problems.

The purpose is to provide.
前記従来の課題を解決するために、本発明の溶解装置は、水回路と、無機化合物と、前記無機化合物を収納する収納手段とを備え、前記無機化合物を溶解させた水を、前記水回路から流出させるとともに、前記無機化合物の水への溶解度が１５ｐｐｍ以下であることを特徴とするものである。 In order to solve the conventional problems, a dissolution apparatus of the present invention includes a water circuit, an inorganic compound, and a storage unit that stores the inorganic compound, and water in which the inorganic compound is dissolved is supplied to the water circuit. And the solubility of the inorganic compound in water is 15 ppm or less.
これによって、水に多量の無機化合物が溶解して水回路から流出しないので、無機化合物を多量に保持する必要がなく、さらには、溶解濃度抑制手段等を必要としないため、コンパクトかつ簡単な構成で、使用性の高い溶解装置を提供できる。 As a result, a large amount of inorganic compound dissolves in water and does not flow out of the water circuit, so there is no need to retain a large amount of inorganic compound, and furthermore, no means for suppressing the dissolved concentration is required, so a compact and simple configuration Thus, a highly usable melting apparatus can be provided.
また、水と無機化合物の間の溶解濃度差で物質が移動する、物質拡散（フィックの法則）の原理で、水に無機化合物を溶解させることが可能となるため、これまで必要としていた電源回路と絶縁回路が削減でき、コンパクト化と低コスト化を実現することができ、さらには、電力不要の原理であるため、消費電力量を抑えることもできる。 In addition, it is possible to dissolve inorganic compounds in water based on the principle of substance diffusion (Fick's law), in which substances move due to the difference in dissolution concentration between water and inorganic compounds. Insulating circuits can be reduced, and downsizing and cost reduction can be realized. Furthermore, since it is a principle that does not require power, the amount of power consumption can be suppressed.

また、水と無機化合物の間の溶解濃度差で物質が移動する、物質拡散（フィックの法則）の原理で、水に無機化合物を溶解させることが可能となるため、これまで必要としていた電源回路と絶縁回路が削減でき、コンパクト化と低コスト化を実現することができ、さらには、電力不要の原理であるため、消費電力量を抑えることもできる。 In addition, it is possible to dissolve inorganic compounds in water based on the principle of substance diffusion (Fick's law), in which substances move due to the difference in dissolution concentration between water and inorganic compounds.

Since the inorganic compound dissolving function can be maintained for more than half a year and the inorganic compound dissolving function can be maintained, the frequency of replenishing the inorganic compound can be reduced, so that convenience can be enhanced.

以下、本発明の実施の形態について、図面を参照しながら説明する。なお、この実施の形態によって本発明が限定されるものではない。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.
（実施の形態１）
図１は、本発明の第１の実施の形態における溶解装置の構造図を示すものである。
(Embodiment 1)
FIG. 1 is a structural diagram of a melting apparatus according to the first embodiment of the present invention.
図１において、無機化合物１１は、粉末状または顆粒状、あるいは、粉末状と顆粒状との混合物であり、無機化合物収納容器（無機化合物収納手段）１２に収納される。無機化合物１１は、水に対して溶解性を持つ。図１中の無機化合物１１は径が異なる顆粒状のものであり、これを多層状となるように構成すると、無機化合物収納容器１２内には多孔質の空間が形成される。無機化合物収納容器１２は、水回路１３によって連通され、溶解装置１４を構成する。 In FIG. 1, an inorganic compound 11 is in the form of powder or granules, or a mixture of powder and granules, and is stored in an inorganic compound storage container (inorganic compound storage means) 12. The inorganic compound 11 is soluble in water. The inorganic compound 11 in FIG. 1 is in the form of granules having different diameters. When this is configured to be a multilayer, a porous space is formed in the inorganic compound storage container 12. The inorganic compound container 12 is communicated by a water circuit 13 and constitutes a dissolving device 14.
以上のように構成された給湯装置について、以下その動作、作用を説明する。水回路１３から溶解装置１４に流入する水は、無機化合物収納容器１２に形成される多孔質の空間を通過する。水には粘性があるため、多孔質の空間を通過する際に無機化合物１１の表面から表面近傍の領域には速度境界層が生成される。 About the hot water supply apparatus comprised as mentioned above, the operation | movement and an effect | action are demonstrated below. Water flowing from the water circuit 13 into the dissolving device 14 passes through a porous space formed in the inorganic compound storage container 12. Since water has viscosity, a velocity boundary layer is generated from the surface of the inorganic compound 11 to the region near the surface when passing through the porous space.
図２はその速度境界層の状態を示す図である。無機化合物１１の表面近傍の速度境界層の流速は小さく、多孔質空間の中心部を通過する流速は大きい分布となる。無機化合物１１は水に対して溶解性を持つため、無機化合物１１の表面近傍の１１の表面分子は、表面近傍の水に溶解し、水の溶解濃度が上昇する。表面近傍の水は流速が小さいため、溶解濃度は高い値となる。これに対して流速の大きい多孔質空間の中心部の流れる水の溶解濃度は低い。このとき、水中に溶解する無機化合物の濃度差が生じた場合は、濃度差に応じて高い方から低い物質が移動する（フィックの法則）ため、表面近傍の水に溶解した無機化合物は濃度の低い中心の水に移動する。この物質拡散の原理を利用することで、無機化合物１１を多孔質空間内の水に溶解させることができる。 FIG. 2 is a diagram showing the state of the velocity boundary layer. The flow velocity of the velocity boundary layer near the surface of the inorganic compound 11 is small, and the flow velocity passing through the central portion of the porous space has a large distribution. Since the inorganic compound 11 is soluble in water, 11 surface molecules near the surface of the inorganic compound 11 are dissolved in water near the surface, and the dissolution concentration of water increases. Since the water near the surface has a low flow rate, the dissolved concentration has a high value. On the other hand, the dissolved concentration of water flowing in the center of the porous space having a high flow rate is low. At this time, if there is a difference in the concentration of the inorganic compound dissolved in water, the lower substance moves from the higher one according to the concentration difference (Fick's law), so the inorganic compound dissolved in the water near the surface Move to low center water. By utilizing this principle of substance diffusion, the inorganic compound 11 can be dissolved in water in the porous space.
ここで、無機化合物１１について説明する。無機化合物１１は、水に対する溶解度が使用温度範囲において１５ｐｐｍ（無機化合物［ｍｇ］／水［Ｌ］）以下のものを用いることができる。溶解度は、溶媒である水の体積１［Ｌ］に対して、溶質である無機化合物が飽和まで溶解した時の質量［ｍｇ］として表される。 Here, the inorganic compound 11 will be described. As the inorganic compound 11, those having a solubility in water of 15 ppm (inorganic compound [mg] / water [L]) or less in the operating temperature range can be used. The solubility is expressed as a mass [mg] when an inorganic compound as a solute is dissolved to saturation with respect to a volume 1 [L] of water as a solvent.
無機化合物１１として酸化亜鉛（ＺｎＯ）を用いることができる。図３に酸化亜鉛の温度と飽和溶解濃度（溶解度）の関係を示す。給湯装置の使用温度である８０℃までの範囲でＺｎＯ濃度は２ｐｐｍ以下であり、溶解装置１４に通水したさいの酸化亜鉛の消費量を少なくすることができるので、無機化合物１１の充填量を少なくすることができ、無機化合物収納容器１２の容積を小さくすることができ、溶解装置１４をコンパクト化、低コスト化することができる。給湯機の本体筐体内に溶解装置１４を収納するためには、無機化合物収納容器１２を小さくする必要があり、無機化合物１１の充填量を少なくする必要があるが、溶解度の高い無機化合物を用いた場合は、無機化合物１１の消費量を抑制するために、溶解量を制御するポンプ等の溶解抑制手段が別途必要になり、構成が複雑になりコストアップとなる。 As the inorganic compound 11, zinc oxide (ZnO) can be used. FIG. 3 shows the relationship between the temperature of zinc oxide and the saturated dissolution concentration (solubility). In the range up to 80 ° C., which is the operating temperature of the hot water supply device, the ZnO concentration is 2 ppm or less, and it is possible to reduce the consumption amount of zinc oxide when water is passed through the dissolving device 14. The volume of the inorganic compound storage container 12 can be reduced, and the dissolution apparatus 14 can be made compact and reduced in cost. In order to store the dissolving device 14 in the main body housing of the water heater, it is necessary to make the inorganic compound storage container 12 small, and it is necessary to reduce the filling amount of the inorganic compound 11, but an inorganic compound having high solubility is used. In that case, in order to suppress the consumption of the inorganic compound 11, a dissolution suppressing means such as a pump for controlling the dissolution amount is required separately, which complicates the configuration and increases the cost.
一方、溶解抑制手段を設けることなく、溶解度の高い無機化合物を用いた場合は、溶解装置１４に通水した際、無機化合物１１の消費量が多くなり、無機化合物収納容器１２に無機化合物を多量に充填する必要があるため、溶解装置１４を給湯機本体内に収納することができなくなり、別途溶解装置１４の筐体を構成する必要があることから、給湯装置の
構成が複雑となりコストアップとなる。
On the other hand, when an inorganic compound with high solubility is used without providing a dissolution inhibiting means, the amount of consumption of the inorganic compound 11 increases when water is passed through the dissolving device 14, and a large amount of inorganic compound is contained in the inorganic compound storage container 12. Therefore, the melting device 14 cannot be stored in the main body of the water heater, and the housing of the melting device 14 needs to be configured separately, which complicates the configuration of the water heater and increases costs. Become.
無機化合物１１の溶解度は、１５ｐｐｍ以下としたことから、無機化合物１１の消費量を少なくすることができるので、無機化合物収納容器１２への無機化合物１１の充填量を少なくすることができるので容積を小さくすることができ、複雑な構成を必要とせず給湯機の本体筐体内に溶解装置１４を収納することができるので、別途溶解抑制手段等を必要とせず、コンパクトかつ簡単な構成で信頼性を向上することが可能となり、低コスト化を実現することができる。 Since the solubility of the inorganic compound 11 is set to 15 ppm or less, the consumption amount of the inorganic compound 11 can be reduced, so that the filling amount of the inorganic compound 11 into the inorganic compound storage container 12 can be reduced, so that the volume is increased. Since the melting device 14 can be housed in the main body casing of the water heater without requiring a complicated configuration, it is possible to reduce the size and reduce the need for a separate melting suppression means, etc., and the reliability can be improved with a compact and simple configuration. It becomes possible to improve, and cost reduction can be realized.
無機化合物収納容器１２は、１日の無機化合物の溶解量に対し１８０倍以上を収納しており、給湯機の無機化合物溶解機能を半年以上保つことができ、無機化合物１１を補充する頻度を減少することができるので、メンテナンスの手間を軽減することができる。 The inorganic compound storage container 12 stores more than 180 times the amount of inorganic compound dissolved per day, can maintain the inorganic compound dissolving function of the water heater for more than half a year, and reduces the frequency of replenishing the inorganic compound 11 Therefore, the maintenance work can be reduced.
なお、無機化合物１１として用いることが出来る材料は酸化亜鉛以外に、亜鉛化合物として、酸化亜鉛（ＺｎＯ）、塩基性炭酸亜鉛（ｍＺｎＣＯ３・ｎＺｎ（ＯＨ）２）、水酸化亜鉛（Ｚｎ（ＯＨ）２）、亜鉛置換型ゼオライト、亜鉛置換型キレート、亜鉛シリカゲル担持物、であり、これらを単一または組み合わせて用いることができる。また、硫酸カルシウム、水酸化マグネシウム、鉄化合物（酸化鉄、水酸化鉄）、酸化銅、酸化ケイ素、二酸化マンガン、水酸化コバルト、酸化チタン、塩化銀、硫酸バリウムを用いることができる。 In addition to zinc oxide, materials that can be used as the inorganic compound 11 include zinc oxide (ZnO), basic zinc carbonate (mZnCO 3 .nZn (OH) 2 ), and zinc hydroxide (Zn (OH)). 2 ), zinc-substituted zeolite, zinc-substituted chelate, and zinc silica gel-supported material, which can be used singly or in combination. Further, calcium sulfate, magnesium hydroxide, iron compound (iron oxide, iron hydroxide), copper oxide, silicon oxide, manganese dioxide, cobalt hydroxide, titanium oxide, silver chloride, and barium sulfate can be used.
以上のように、本実施の形態においては、無機化合物と、無機化合物収納容器とを有し、無機化合物収納容器を水回路で接続した溶解装置を備えた給湯装置とした。 As mentioned above, in this Embodiment, it was set as the hot-water supply apparatus provided with the melt | dissolution apparatus which has an inorganic compound and the inorganic compound storage container, and connected the inorganic compound storage container with the water circuit.
これによって、水と無機化合物の間の溶解濃度差で物質が移動する、物質拡散（フィックの法則）の原理で、水に無機化合物を溶解させることが可能となる。従って、これまで必要としていた電源回路と絶縁回路が削減できるので、コンパクト化、低コスト化、さらには消費電力量を抑えた給湯装置とすることができる。また、溶解装置を通過する水回路の水に多量に無機化合物が溶解しないので、無機化合物を多量に保持する必要がなく、もしくは、溶解抑制手段を必要とせず、コンパクトかつ簡単な構成で信頼性を向上することが可能となり、メンテナンス頻度を軽減、低コスト化を実現することができる。 This makes it possible to dissolve the inorganic compound in water based on the principle of substance diffusion (Fick's law) in which the substance moves due to the difference in the dissolved concentration between water and the inorganic compound. Therefore, since the power supply circuit and the insulation circuit which have been required so far can be reduced, it is possible to provide a hot water supply apparatus that is compact and low in cost, and further reduces power consumption. In addition, since a large amount of inorganic compound does not dissolve in the water in the water circuit passing through the dissolution apparatus, there is no need to hold a large amount of inorganic compound or no dissolution suppression means is required, and the compact and simple configuration ensures reliability. The maintenance frequency can be reduced and the cost can be reduced.
尚、無機化合物を、亜鉛を含む亜鉛化合物（酸化亜鉛、炭酸亜鉛など）とした場合、以下の効果を得ることができる。亜鉛は比較的要求量の多いヒトの必須元素の一つであり、通常の食事からの供給では欠乏しやすく、栄養強化目的で、食品に添加される元素である。これに対しては、浴槽に亜鉛を溶解させた水を供給することで、入浴中に経皮吸収による栄養強化を行うことができる。 In addition, when the inorganic compound is a zinc compound containing zinc (such as zinc oxide or zinc carbonate), the following effects can be obtained. Zinc is one of the essential elements of humans with relatively large demands, and is easily deficient when supplied from a normal diet. It is an element added to foods for the purpose of enhancing nutrition. On the other hand, the nutrition enhancement by percutaneous absorption can be performed during bathing by supplying water in which zinc is dissolved in the bathtub.
また、亜鉛化合物の酸化亜鉛は、日本薬局方や化粧品原料基準に定められた規格に準拠することで、医薬品や化粧品として使用することができる材料であり、主にヒトの肌の角質層に対して収れん作用、消炎作用などの作用を与え、肌の角質層の状態を良好に保つことができる。 In addition, zinc oxide, a zinc compound, is a material that can be used as pharmaceuticals and cosmetics by complying with the standards defined in the Japanese Pharmacopoeia and Cosmetic Raw Material Standards. It is mainly used for the stratum corneum of human skin. It gives effects such as astringent action and anti-inflammatory action, and can keep the skin stratum corneum in good condition.

FIG. 4 shows a structural diagram of a melting apparatus according to the second embodiment of the present invention.
図４において、無機化合物１１は、粉末状または顆粒状、あるいは、粉末状と顆粒状との混合物であり、無機化合物収納容器（無機化合物収納手段）１２に収納される。無機化合物１１は、水に対して溶解性を持つ。図４中の無機化合物１１は径が異なる顆粒状のものであり、これを多層状となるように構成すると、無機化合物収納容器１２内には多孔質
の空間が形成される。濾過手段１６は、複数の***を有する***体１５により構成され、濾過手段収納容器１７に収納される。無機化合物収納容器１２と濾過手段収納容器１７は、順に水回路１３によって連通され、無機化合物収納容器１２は濾過手段収納容器１７の上流側となるように溶解装置１４を構成する。
In FIG. 4, the inorganic compound 11 is in the form of powder or granules, or a mixture of powder and granules, and is stored in an inorganic compound storage container (inorganic compound storage means) 12. The inorganic compound 11 is soluble in water. The inorganic compound 11 in FIG. 4 is in the form of granules having different diameters, and when this is configured to be multilayered, a porous space is formed in the inorganic compound storage container 12. The filtering means 16 is constituted by a small hole body 15 having a plurality of small holes, and is stored in a filtering means storage container 17. The inorganic compound storage container 12 and the filtration means storage container 17 are sequentially communicated by the water circuit 13, and the dissolution apparatus 14 is configured so that the inorganic compound storage container 12 is on the upstream side of the filtration means storage container 17.
以上のように構成された給湯装置について、以下その動作、作用を説明する。水回路１３から溶解装置１４に流入する水は、無機化合物収納容器１２に形成される多孔質の空間を通過する。水には粘性があるため、多孔質の空間を通過する際に無機化合物１１の表面から表面近傍の領域には速度境界層が生成される。図２はその速度境界層の状態を示す図である。無機化合物１１の表面近傍の速度境界層の流速は小さく、多孔質空間の中心部を通過する流速は大きい分布となる。無機化合物１１は水に対して溶解性を持つため、無機化合物１１の表面近傍の１１の表面分子は、表面近傍の水に溶解し、水の溶解濃度が上昇する。表面近傍の水は流速が小さいため、溶解濃度は高い値となる。 About the hot water supply apparatus comprised as mentioned above, the operation | movement and an effect | action are demonstrated below. Water flowing from the water circuit 13 into the dissolving device 14 passes through a porous space formed in the inorganic compound storage container 12. Since water has viscosity, a velocity boundary layer is generated from the surface of the inorganic compound 11 to the region near the surface when passing through the porous space. FIG. 2 is a diagram showing the state of the velocity boundary layer. The flow velocity of the velocity boundary layer near the surface of the inorganic compound 11 is small, and the flow velocity passing through the central portion of the porous space has a large distribution. Since the inorganic compound 11 is soluble in water, 11 surface molecules near the surface of the inorganic compound 11 are dissolved in water near the surface, and the dissolution concentration of water increases. Since the water near the surface has a low flow rate, the dissolved concentration has a high value.
これに対して流速の大きい多孔質空間の中心部の流れる水の溶解濃度は低い。このとき、水中に溶解する無機化合物の濃度差が生じた場合は、濃度差に応じて高い方から低い物質が移動する（フィックの法則）ため、表面近傍の水に溶解した無機化合物は濃度の低い中心の水に移動する。この物質拡散の原理を利用することで、無機化合物１１を多孔質空間内の水に溶解させることができる。濾過手段１６は、無機化合物収納容器１２内の水勢によって無機化合物１１の顆粒が無機化合物収納容器１２から流出しようとした場合、これを防止するものである。 On the other hand, the dissolved concentration of water flowing in the center of the porous space having a high flow rate is low. At this time, if there is a difference in the concentration of the inorganic compound dissolved in water, the lower substance moves from the higher one according to the concentration difference (Fick's law), so the inorganic compound dissolved in the water near the surface Move to low center water. By utilizing this principle of substance diffusion, the inorganic compound 11 can be dissolved in water in the porous space. The filtering means 16 prevents the granules of the inorganic compound 11 from flowing out of the inorganic compound storage container 12 due to the water in the inorganic compound storage container 12.
以上のように、本実施の形態においては、無機化合物と、無機化合物収納容器と、濾過手段と、濾過手段収納容器とを有し、無機化合物収納容器、濾過手段収納容器の順に水回路で接続した溶解装置を備えた給湯装置とした。 As described above, in the present embodiment, the inorganic compound, the inorganic compound storage container, the filtration means, and the filtration means storage container are provided, and the inorganic compound storage container and the filtration means storage container are connected in this order in the water circuit. It was set as the hot-water supply apparatus provided with the melt | dissolution apparatus.
これによって、図１に示す溶解装置と同様に、水と無機化合物の間の溶解濃度差で物質が移動する、物質拡散（フィックの法則）の原理で、水に無機化合物を溶解させることが可能となる。従って、これまで必要としていた電源回路と絶縁回路が削減できるので、コンパクト化、低コスト化、さらには消費電力量を抑えた給湯装置とすることができる。 As a result, the inorganic compound can be dissolved in water based on the principle of substance diffusion (Fick's law), in which the substance moves according to the difference in dissolved concentration between water and the inorganic compound, similar to the dissolution apparatus shown in FIG. It becomes. Therefore, since the power supply circuit and the insulation circuit which have been required so far can be reduced, it is possible to provide a hot water supply apparatus that is compact and low in cost, and further reduces power consumption.
図５は、溶解装置の無機化合物１１と***体１５の寸法の関係を示す例である。図５において、***体１５は径の異なる複数の***１５ａ、１５ｂ、１５ｃから構成される。 FIG. 5 is an example showing the relationship between the dimensions of the inorganic compound 11 and the small hole body 15 of the melting apparatus. In FIG. 5, the small hole body 15 is composed of a plurality of small holes 15a, 15b and 15c having different diameters.
図６は、***体１５の構成例である。（ａ）は、線形状の繊維で角状の***を形成したものである。（ｂ）は、所定の厚さの板に、複数種の径の***を施したものである。（ｃ）は、粒状の非溶解材料を多層状として多孔質空間を形成したものである。何れも、無機化合物収納容器１２内の水勢によって無機化合物１１の顆粒が無機化合物収納容器１２から流出しようとした場合、これを防止するものであるが、この構成と形状の限りではない。 FIG. 6 is a configuration example of the small hole body 15. (A) forms a square-shaped small hole with a linear fiber. (B) is a plate having a predetermined thickness and small holes having a plurality of types of diameters. (C) forms a porous space by using a granular non-dissolving material as a multilayer. In any case, when the granules of the inorganic compound 11 are about to flow out of the inorganic compound storage container 12 due to the water flow in the inorganic compound storage container 12, this is prevented, but the configuration and shape are not limited thereto.
溶解装置１４を流出する溶解濃度は、無機化合物収納容器１２を通過する水流速と、無機化合物１１の水と接触する表面積等で決定される。溶解装置１４の溶解濃度を所定値とする場合は、無機化合物１１の全表面積をある範囲とする必要があるため、図５の無機化合物収納容器１２に収納する無機化合物１１の粒径をある一定の範囲内のサイズに選別したものを利用する必要がある。選別を行うと、コストアップの要因となるため、複数の径を有する無機化合物１１の中において、無機化合物１１の最大粒径Ｄ１に対して、***体１５の***１５ａの径Ｄ２は、Ｄ２＜Ｄ１とした場合、以下の効果を得ることができる。Ｄ２未満の粒径の無機化合物１１は、***１５ａ、１５ｂ、１５ｃから流出する。利用初期は粒径の小さいものは、溶解装置１４外へ流出するが、所定時間経過後は、Ｄ２以上の
粒径の無機化合物１１は無機化合物収納容器１２内に貯留され続ける。この状態が形成された場合、無機化合物１１の粒径をある一定の範囲内のサイズに選別したことと同等となる。従って、サイズが混在する無機化合物１１を用いても、目的とする濃度を水に溶解させる構造となる。
The dissolution concentration flowing out of the dissolution apparatus 14 is determined by the flow rate of water passing through the inorganic compound storage container 12 and the surface area of the inorganic compound 11 in contact with water. When the dissolution concentration of the dissolution apparatus 14 is set to a predetermined value, since the total surface area of the inorganic compound 11 needs to be within a certain range, the particle size of the inorganic compound 11 stored in the inorganic compound storage container 12 in FIG. It is necessary to use the one selected for the size within the range. Since the selection causes a cost increase, among the inorganic compounds 11 having a plurality of diameters, the diameter D2 of the small hole 15a of the small hole body 15 is D2 <with respect to the maximum particle diameter D1 of the inorganic compound 11. In the case of D1, the following effects can be obtained. The inorganic compound 11 having a particle diameter less than D2 flows out from the small holes 15a, 15b, and 15c. In the initial stage of use, the one having a small particle size flows out of the dissolving device 14, but after a predetermined time has passed, the inorganic compound 11 having a particle size of D2 or more continues to be stored in the inorganic compound storage container 12. When this state is formed, it is equivalent to selecting the particle size of the inorganic compound 11 to a size within a certain range. Therefore, even if the inorganic compound 11 in which the sizes are mixed is used, the target concentration is dissolved in water.

(Embodiment 3)
FIG. 7 shows a block diagram of a hot water supply apparatus according to the second embodiment of the present invention.
図７において、圧縮機２２、給湯熱交換器２３、減圧手段２４、蒸発器２５を冷媒回路２６で順に環状に接続してヒートポンプユニット２１を構成している。貯湯ユニット２７の貯湯タンク２８には水が貯留されており、出湯回路３０は貯湯タンク２８、給湯水ポンプ２９、給湯熱交換器２３、貯湯タンク２８を順に接続する回路である。浴槽水加熱回路３５は、貯湯タンク２８、風呂熱交換器３３、加熱ポンプ３４、貯湯タンク２８を順に接続する回路であり、風呂熱交換器３３の他方の回路には浴槽４２が接続されている。 In FIG. 7, a compressor 22, a hot water supply heat exchanger 23, a decompression means 24, and an evaporator 25 are connected in an annular manner in order with a refrigerant circuit 26 to constitute a heat pump unit 21. Water is stored in a hot water storage tank 28 of the hot water storage unit 27, and a hot water discharge circuit 30 is a circuit that connects the hot water storage tank 28, a hot water supply pump 29, a hot water supply heat exchanger 23, and a hot water storage tank 28 in this order. The bathtub water heating circuit 35 is a circuit that connects the hot water storage tank 28, the bath heat exchanger 33, the heating pump 34, and the hot water storage tank 28 in order, and the bathtub 42 is connected to the other circuit of the bath heat exchanger 33. .
浴槽水循環回路４１は、浴槽４２、浴槽水を搬送する浴槽水ポンプ４０、風呂熱交換器３３を順に接続する回路である。浴槽水注湯回路３９は、貯湯タンク２８の水を、浴槽水循環回路４１を経由して浴槽４２へ注湯する回路である。この回路には貯湯タンク２８の高温の水と水道水を混合する浴槽水混合弁３６、注湯する水温を検知する温度検知手段３７、浴槽水注湯回路３９の回路の開閉を行う浴槽水注湯弁３８を順に備える。溶解装置１４は浴槽水注湯弁３８の下流側の浴槽水注湯回路３９に本体の筐体に収納するように設けた。 The bathtub water circulation circuit 41 is a circuit which connects the bathtub 42, the bathtub water pump 40 which conveys bathtub water, and the bath heat exchanger 33 in order. The bathtub water pouring circuit 39 is a circuit for pouring the water in the hot water storage tank 28 to the bathtub 42 via the bathtub water circulation circuit 41. In this circuit, a bath water mixing valve 36 for mixing hot water in the hot water storage tank 28 and tap water, temperature detecting means 37 for detecting the temperature of the pouring water, and bath water pouring for opening and closing the bath water pouring circuit 39. The hot water valve 38 is provided in order. The melting device 14 was provided in the bathtub water pouring circuit 39 on the downstream side of the bathtub water pouring valve 38 so as to be housed in the housing of the main body.
ヒートポンプユニット２１で貯湯タンク２８に貯留された水を加熱する運転は、以下のような動作となる。貯湯タンク２８の水は、給湯水ポンプ２９によって給湯熱交換器２３へ搬送され、ヒートポンプサイクル動作によって加熱される。給湯水ポンプ２９は給湯熱交換器２３で加熱された給湯水の温度が予め決定した温度になる様に、出湯回路３０の流量を制御する。 The operation of heating the water stored in the hot water storage tank 28 by the heat pump unit 21 is as follows. The water in the hot water storage tank 28 is conveyed to the hot water supply heat exchanger 23 by the hot water supply water pump 29 and heated by the heat pump cycle operation. The hot water supply pump 29 controls the flow rate of the hot water supply circuit 30 so that the temperature of the hot water heated by the hot water supply heat exchanger 23 becomes a predetermined temperature.
浴槽４２への湯張り、並びに、浴槽水の加熱は以下のような動作となる。浴槽水注湯回路３９の浴槽水混合弁３６は、温度検知手段３７で検知する注湯温度がリモコン等（図示せず）で予め設定された温度となるように、高温の湯と水道水の混合割合を調整する。所定温度となった浴槽水は、浴槽水注湯回路３９、浴槽水循環回路４１を順に経由して浴槽４２へ流出する。一方、浴槽４２の浴槽水を加熱する場合は、貯湯タンク２８に貯留された高温の湯を、浴槽水加熱ポンプ３４によって風呂熱交換器３３へ搬送し、浴槽水ポンプ４０より搬送された浴槽水を加熱する。風呂熱交換器３３で浴槽水を加熱して温度が下がった給湯水は、給湯水下部回路３１が接続する貯湯タンク２８の下部より内部へ流入する。 The filling of the bathtub 42 and the heating of the bathtub water are as follows. The bathtub water mixing valve 36 of the bathtub water pouring circuit 39 has a hot water and tap water so that the pouring temperature detected by the temperature detecting means 37 becomes a temperature preset by a remote controller or the like (not shown). Adjust the mixing ratio. The bathtub water having a predetermined temperature flows out into the bathtub 42 through the bathtub water pouring circuit 39 and the bathtub water circulation circuit 41 in this order. On the other hand, when heating the bathtub water in the bathtub 42, the hot water stored in the hot water storage tank 28 is conveyed to the bath heat exchanger 33 by the bathtub water heating pump 34, and the bathtub water conveyed from the bathtub water pump 40. Heat. Hot-water supply water whose temperature has been lowered by heating the bath water in the bath heat exchanger 33 flows into the interior from the lower part of the hot-water storage tank 28 to which the hot-water supply lower circuit 31 is connected.
以上のように構成された給湯装置について、以下その動作、作用を説明する。利用者が浴槽４２へ湯はりを行う場合は、リモコン等で湯はり動作の指示操作を行う。リモコン操作後、予め設定された温度に浴槽水混合弁３６で調整された水が、浴槽水注湯弁３８を閉から開に制御した場合に、溶解装置１４、浴槽水循環回路４１を経由して浴槽４２に流出する。水が溶解装置１４を通過する際に、無機化合物１１が水に溶解するので、浴槽４２に湯はり動作と同時に、無機化合物１１を溶解させた水が浴槽４２に流入する。 About the hot water supply apparatus comprised as mentioned above, the operation | movement and an effect | action are demonstrated below. When the user hot waters the bathtub 42, the remote controller or the like performs a hot water operation instruction operation. After the remote control operation, when the water adjusted by the bathtub water mixing valve 36 to a preset temperature controls the bathtub water pouring valve 38 from closed to open, it passes through the melting device 14 and the bathtub water circulation circuit 41. It flows out into the bathtub 42. Since the inorganic compound 11 is dissolved in water when the water passes through the dissolving device 14, the water in which the inorganic compound 11 is dissolved flows into the bathtub 42 simultaneously with the hot water operation in the bathtub 42.
溶解装置１４は、浴槽水注湯弁３８の下流側としたが、浴槽水注湯弁３８が開から閉へ制御された場合は、ウォーターハンマー現象が発生し、上流側の回路に設けている、浴槽水混合弁３６、貯湯タンク２８等は水道圧以上の水圧負荷を与える。下流側に設けることによって、溶解装置１４への水圧負荷が掛からない。 Although the melting device 14 is on the downstream side of the bathtub water pouring valve 38, when the bathtub water pouring valve 38 is controlled from opening to closing, a water hammer phenomenon occurs and is provided in the upstream circuit. The bathtub water mixing valve 36, the hot water storage tank 28, etc. give a water pressure load higher than the water pressure. By providing it on the downstream side, the hydraulic load on the melting apparatus 14 is not applied.
以上のように、本実施の形態においては、浴槽水注湯回路と、浴槽水注湯弁を備え、浴槽水注湯弁、溶解装置の順に浴槽水注湯回路に備えた給湯装置とした。これにより、溶解装置は浴槽への湯はり停止時などに生じるウォーターハンマー現象（浴槽水注湯回路等の水圧上昇）の影響を受けないため、溶解装置の耐圧構造を簡素化することができる。さらに、浴槽への湯はりの水流を利用するため、湯はりと同時に無機化合物を溶解させた水を浴槽へ供給できるので、利便性が向上する。 As mentioned above, in this Embodiment, it was set as the hot-water supply apparatus provided with the bathtub water-pouring circuit and the bathtub water-pouring valve, and equipped with the bathtub water-pouring circuit in order of the bathtub water-pouring valve and the melting apparatus. Thereby, since the melting device is not affected by the water hammer phenomenon (water pressure increase in the bathtub water pouring circuit or the like) that occurs when hot water to the bathtub is stopped, the pressure resistance structure of the melting device can be simplified. Furthermore, since the water flow of the hot water to the bathtub is used, the water in which the inorganic compound is dissolved can be supplied to the bathtub at the same time as the hot water, thereby improving convenience.
本発明において、溶解装置１４は給湯機の本体筐体に収納し、浴槽水注湯回路３９としているが、浴槽水循環回路４１に設けても、浴槽４２へ無機化合物１１を溶解させた水を供給することが出来る。また、本体筐体外部の浴槽水循環回路４１に設けることも可能であるが、本体筐体内部の雰囲気温度は、低外気温時であっても貯湯タンク２８からの放熱により、筐体内部の雰囲気は常時加温されるため、溶解装置１４の凍結防止などの断熱が不要、または簡素化できる。 In the present invention, the melting device 14 is housed in the main body housing of the water heater and serves as a bathtub water pouring circuit 39. However, even if the bath water circulation circuit 41 is provided, water in which the inorganic compound 11 is dissolved is supplied to the bathtub 42. I can do it. Although it is possible to provide in the bathtub water circulation circuit 41 outside the main body casing, the atmospheric temperature inside the main body casing is reduced by heat radiation from the hot water storage tank 28 even at a low outside temperature. Is always heated, so that heat insulation such as prevention of freezing of the melting device 14 is unnecessary or simplified.
また、給湯機を貯湯式給湯機とした場合、貯湯タンクには高温の湯を貯湯するので、この高温の湯を溶解装置へ供給することによって機器の殺菌、滅菌を行うことができる。また、水中に溶け込んでいる残留塩素が貯留中に少なくなるので、本体の材質は耐腐食性材料ではなく、安価な汎用部品を使うことができる。 Further, when the hot water heater is a hot water storage type hot water heater, high temperature hot water is stored in the hot water storage tank, so that the equipment can be sterilized and sterilized by supplying the hot water to the melting device. Further, since the residual chlorine dissolved in the water is reduced during storage, the main body is not a corrosion-resistant material, and inexpensive general-purpose parts can be used.

FIG. 8 shows a structural diagram of a melting apparatus according to the second embodiment of the present invention.
図８において、溶解装置１４の入口と出口は浴槽水注湯回路３９に接続されている。無機化合物１１を収納する無機化合物収納容器１２の相当直径ｄ１、浴槽水注湯回路３９の相当直径ｄ２とした場合、図８においてそれぞれをｄ１＞ｄ２となる大きさなるように決定した。 In FIG. 8, the inlet and outlet of the melting device 14 are connected to a bathtub water pouring circuit 39. When the equivalent diameter d1 of the inorganic compound storage container 12 that stores the inorganic compound 11 and the equivalent diameter d2 of the bathtub water pouring circuit 39 are set, the sizes are determined so as to satisfy d1> d2 in FIG.
以上のように構成された給湯装置について、以下その動作、作用を説明する。水回路１３に対して、無機化合物１１を収納した無機化合物収納容器１２、濾過手段１６を設けたので、溶解装置１４を水が通過する際に、圧力損失が生じる。圧力損失が生じると、浴槽４２へ供給する水の流量が低下する。 About the hot water supply apparatus comprised as mentioned above, the operation | movement and an effect | action are demonstrated below. Since the inorganic compound storage container 12 storing the inorganic compound 11 and the filtering means 16 are provided for the water circuit 13, pressure loss occurs when water passes through the dissolving device 14. When pressure loss occurs, the flow rate of water supplied to the bathtub 42 decreases.
ここで、無機化合物収納容器１２の相当直径ｄ１を、浴槽水注湯回路３９の相当直径ｄ２に対して、ｄ１＞ｄ２となる大きさとすると、無機化合物収納容器１２の平均流速ｕ１は、浴槽水注湯回路３９の平均流速ｕ２より小さくなる。水回路の流体の圧力損失は、流体の平均流速の２乗に比例するため、溶解装置１４を通過する際の圧力損失の増加を低減させることができる。 Here, assuming that the equivalent diameter d1 of the inorganic compound storage container 12 is such that d1> d2 with respect to the equivalent diameter d2 of the bathtub water pouring circuit 39, the average flow velocity u1 of the inorganic compound storage container 12 is the bath water. It becomes smaller than the average flow velocity u2 of the pouring circuit 39. Since the pressure loss of the fluid in the water circuit is proportional to the square of the average flow velocity of the fluid, an increase in the pressure loss when passing through the dissolving device 14 can be reduced.
以上のように、本実施の形態においては、無機化合物収納容器の相当直径を、溶解装置を接続する浴槽水注湯回路の相当直径よりも大とすることにより、無機化合物を通過する水流による圧力損失を低減し、浴槽への湯はり時間を早く完了することができる。 As mentioned above, in this Embodiment, the pressure by the water flow which passes an inorganic compound is made larger by making the equivalent diameter of an inorganic compound storage container larger than the equivalent diameter of the bathtub water pouring circuit which connects a dissolving device. Loss can be reduced and the hot water filling time for the bathtub can be completed quickly.
以上のように、本発明にかかる給湯装置は、コンパクト化、低コスト化、構成の簡素化、信頼性向上、運転効率向上に繋がり、貯湯式給湯機の他、ガス熱源の給湯機にも利用できる。 As described above, the hot water supply apparatus according to the present invention leads to downsizing, cost reduction, simplified configuration, improved reliability, and improved operation efficiency, and is also used for hot water storage hot water heaters as well as hot water heaters for gas heat sources. it can.
