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 that dissolves inorganic compounds and the like, and a hot water supply apparatus that has a function of supplying dissolved inorganic compounds and the like to a bathtub.
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７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７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. 7 shows a conventional hot water supply apparatus described in Patent Document 1. As shown in FIG. As shown in FIG. 7, 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な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。 An object of the present invention is to solve the above-described conventional problems, and to provide a melting apparatus that supplies an inorganic compound or the like that does not require an electric circuit and is compact and low in operating cost, and a hot water supply apparatus including the melting apparatus. To do.
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、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る無機化合物を包囲する包装体とを備え、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構成としたことを特徴とするものである。 In order to solve the above-described conventional problems, the dissolution apparatus of the present invention includes a water circuit and a package surrounding an inorganic compound which is a powder or a granule, or a mixture of a powder and a granule, The water in which the inorganic compound is dissolved is configured to flow out from 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。これにより、コンパクト化と低コスト化を実現するとともに、電力不要の原理であるため、消費電力量を抑えることができる。 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, it is possible to reduce the power supply circuit and the insulation circuit that have been required so far. Thereby, while realizing compactness and cost reduction, since it is a principle which does not require electric power, power consumption can be suppressed.
また、包装体が濾過手段としての機能も兼用するので、無機化合物が消耗した後も、容易に補充できて使用性を向上させることができる。 Further, since the package also serves as a filtering means, it can be easily replenished and the usability can be improved even after the inorganic compound is consumed.
本発明によれば、コンパクト化、低コスト化、さらには、消費電力量の抑制を実現した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できる。 ADVANTAGE OF THE INVENTION According to this invention, the melt | dissolution apparatus which supplies the inorganic compound etc. which implement | achieved compactization, cost reduction, and also suppression of the power consumption amount, and a hot water supply apparatus provided with the same can be provided.
第１の発明は、水回路と、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る無機化合物を包囲する包装体とを備え、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構成としたことを特徴とする溶解装置である。 1st invention is equipped with the water circuit and the package which surrounds the inorganic compound which is a powder form or a granular form, or a mixture of a powder form and a granular form, The water which dissolved the said inorganic compound is said, A melting apparatus characterized in that it is configured to flow out of a 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。また、電力不要の原理であるため、消費電力量を抑えることができる。 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, it is possible to reduce the power supply circuit and the insulation circuit that have been required so far. In addition, since it is a principle that does not require power, the power consumption can be suppressed.
また、包装体が濾過手段としての機能も兼用するので、無機化合物が消耗した後も、容易に補充できて使用性を向上させることができる。 Further, since the package also serves as a filtering means, it can be easily replenished and the usability can be improved even after the inorganic compound is consumed.
第２の発明は、湯水を浴槽へ供給する浴槽水注湯回路と、前記浴槽水注湯回路を開閉する浴槽水注湯弁とを備え、前記第１の発明の溶解装置を、前記浴槽水注湯回路に、前記浴槽水注湯弁の下流側に配設したことを特徴とする給湯装置である。 2nd invention is provided with the bathtub water pouring circuit which supplies hot water to a bathtub, and the bathtub water pouring valve which opens and closes the said bath water pouring circuit, The melting apparatus of said 1st invention is the said bath water. In the hot water supply circuit, the hot water supply device is provided on the downstream side of the bathtub water pouring valve.
これによって、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。 Thereby, since the melting apparatus 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 apparatus 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.

第４の発明は、前記第１の発明の溶解装置を、本体筐体内に配設したことを特徴とする給湯装置で、低外気温時であっても貯湯タンク、電源回路などからの僅かな放熱により筐体内の雰囲気は常時加温されているため、溶解装置の凍結防止などの断熱が簡素化、または不要となる。 A fourth invention is a hot water supply apparatus characterized in that the melting apparatus of the first invention is disposed in a main body housing, and even from a hot water storage tank, a power circuit, etc. Since the atmosphere in the housing is always heated by heat radiation, heat insulation such as prevention of freezing of the melting apparatus is simplified or unnecessary.
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、または、粉末状と顆粒状の混合物であり、包装体１３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、包装体１３内には多孔質の空間が形成される。包装体１３は、順に水回路１５によって連通されるように溶解装置１６を構成する。尚、包装体１３は濾過手段としての機能も兼ね備えたものとする。
In FIG. 1, the inorganic compound 11 is a powder, a granule, or a mixture of a powder and a granule and is stored in a package 13. The inorganic compound 11 is soluble in water. The inorganic compound 11 in FIG. 1 is in the form of granules having different diameters, and when this is configured to be multilayered, a porous space is formed in the package 13. The packaging body 13 constitutes the dissolving device 16 so as to communicate with the water circuit 15 in order. The package 13 also has a function as a filtering means.
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１５から溶解装置１６に流入する水は、包装体１３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 15 into the dissolving device 16 passes through a porous space formed in the package 13. 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。 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。 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.
以上のように、本実施の形態においては、無機化合物１１と、前記無機化合物１１を包囲収納した包装体１３とを有し、前記無機化合物１１を包囲収納した包装体１３を無機化合物収納容器１２内に収納し、前記無機化合物収納容器１２に水回路１５を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 11 and the package 13 that surrounds and stores the inorganic compound 11 are included, and the package 13 that surrounds and stores the inorganic compound 11 is used as the inorganic compound storage container 12. The hot water supply device was provided with a melting device that was housed inside and connected with the water circuit 15 to the inorganic compound container 12.
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。 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.
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、図１において、包装体１３は濾過手段としての機能も兼ね備えることにより、複数の***を有している。濾過手段としての機能も兼ね備えた包装体１３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。 Moreover, in FIG. 1, the package 13 has a plurality of small holes by also having a function as a filtering means. The package 13 also having a function as a filtering means 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.
図３は、溶解装置の無機化合物１１と濾過手段としての機能も兼ね備えた包装体１３の寸法の関係を示す例である。図３において、濾過手段としての機能も兼ね備えた包装体１３は径の異なる複数の***１３ａ、１３ｂ、１３ｃから構成される。 FIG. 3 is an example showing the dimensional relationship between the inorganic compound 11 of the dissolving apparatus and the package 13 that also functions as a filtering means. In FIG. 3, the package 13 that also has a function as a filtering means is composed of a plurality of small holes 13a, 13b, and 13c having different diameters.
図４は、濾過手段としての機能も兼ね備えた包装体１３の構成図である。（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、包装体１３内の水勢によって無機化合物１１の顆粒が包装
体１３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. 4 is a configuration diagram of the package 13 that also has a function as a filtering means. (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 package 13 due to the water in the package 13, this is not limited to this configuration and shape.
溶解装置１６を流出する溶解濃度は、包装体１３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１６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３の包装体１３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。 The dissolution concentration flowing out of the dissolution apparatus 16 is determined by the flow rate of water passing through the package 13 and the surface area of the inorganic compound 11 in contact with water. When the dissolution concentration of the dissolution apparatus 16 is set to a predetermined value, the total surface area of the inorganic compound 11 needs to be within a certain range, so the particle size of the inorganic compound 11 stored in the package 13 in FIG. 3 is in a certain range. It is necessary to use the one selected for the size.
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、濾過手段１３の***１３ａ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、***１３ａ、１３ｂ、１３ｃから流出する。利用初期は粒径の小さいものは、溶解装置１６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は包装体１３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。 Since the selection causes a cost increase, among the inorganic compounds 11 having a plurality of diameters, the diameter D2 of the small hole 13a of the filtering means 13 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 size less than D2 flows out from the small holes 13a, 13b, and 13c. In the initial stage of use, those having a small particle size flow out of the melting device 16, 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 package 13. 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.

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１６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 16 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.

The filling of the bathtub 42 and the heating of the bathtub water are as follows. The bath water mixing valve 36 of the bath 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 the bathtub water in the bathtub 42 is heated, 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 18. 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.
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１６、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１６を通過する際に、無機化合物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 at a preset temperature controls the bathtub water pouring valve 38 from closed to open, it passes through the melting device 16 and the bathtub water circulation circuit 41. It flows out into the bathtub 42. When the water passes through the dissolving device 16, the inorganic compound dissolves in the water, so that 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１６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１６への水圧負荷が掛からない。 Although the melting device 16 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 on the downstream side, the hydraulic load on the melting device 16 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１６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１６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 16 is housed in the main body housing of the water heater and serves as a bathtub water pouring circuit 39. However, even if provided in the bathtub water circulation circuit 41, 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 16 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、この高温の湯を化合物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 compound dissolving apparatus. 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.
（実施の形態３）
図６は、本発明の第３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 3)
FIG. 6 shows a structural diagram of a melting apparatus according to the third embodiment of the present invention.
図６において、溶解装置１６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６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. 6, the inlet and outlet of the melting device 16 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１５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、濾過手段収納容器１４を設けたので、溶解装置１６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。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１６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。 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 storage container 14 are provided for the water circuit 15, a pressure loss occurs when water passes through the dissolving device 16. When pressure loss occurs, the flow rate of water supplied to the bathtub 42 decreases. 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 16 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、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, and improvement in operating efficiency, and can be used for a hot water storage hot water heater and a gas heat source hot water heater.
