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、水に対して溶解性を有する。 In FIG. 1, the inorganic compound 11 is a powder, a granule, or a mixture of a powder and a granule, and has solubility in water.
また、無機化合物収納容器12は内部に通水管14を有し、その通水管14を通過した後の水は、無機化合物収納容器12に収納される無機化合物11を溶解する。 Further, the inorganic compound storage container 12 has a water conduit 14 inside, and the water after passing through the water conduit 14 dissolves the inorganic compound 11 stored in the inorganic compound storage container 12.
すなわち、その無機化合物11を溶解する水は、無機化合物収納容器12内を流れ、水流方向を重力方向とは対向した上昇流とし、かつ、この上昇流の流れ方向に向かって拡がる略すり鉢状に、前記無機化合物収納容器12内の無機化合物11を溶解する水流路を形成している。 That is, the water that dissolves the inorganic compound 11 flows in the inorganic compound storage container 12, the water flow direction is an upward flow opposite to the direction of gravity, and the shape of the upward flow spreads in a substantially mortar shape. A water flow path for dissolving the inorganic compound 11 in the inorganic compound storage container 12 is formed.
なお、本実施の形態においては、無機化合物収納容器12内の無機化合物11を溶解させる水流路を略すり鉢状に形成しているが、少なくとも水流路の流入部近傍を、流れ方向
に向かって広がる傾斜部にて形成していれば、以下に記載の効果は満たす。
In the present embodiment, the water channel for dissolving the inorganic compound 11 in the inorganic compound storage container 12 is formed in a substantially mortar shape, but at least the vicinity of the inflow portion of the water channel spreads in the flow direction. If it forms in an inclined part, the effect as described below will be satisfied.
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、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。 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 inorganic compound storage container 12.
濾過手段13は複数の***を有し、無機化合物収納容器12の端部に収納される。無機化合物収納容器12と濾過手段13は、順に水回路15によって連通され、無機化合物収納容器12は濾過手段13の上流側となるように溶解装置16を構成する。 The filtering means 13 has a plurality of small holes and is stored in the end portion of the inorganic compound storage container 12. The inorganic compound storage container 12 and the filtration means 13 are sequentially communicated by a water circuit 15, and the dissolution apparatus 16 is configured so that the inorganic compound storage container 12 is on the upstream side of the filtration means 13.
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。 About the hot water supply apparatus comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.
通水管14を経由して無機化合物収納容器12に流入する水は、重力方向と対向した上昇水流として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。 The water flowing into the inorganic compound storage container 12 through the water conduit 14 passes through a porous space formed in the inorganic compound storage container 12 as an ascending water flow opposed to the direction of gravity.
また、無機化合物収納容器12内では、上流ほど流速が大きくなり、下流になるに従い流速が小さくなる水流速の分布となり、一方、無機化合物11は径が異なる顆粒状のものであることから、顆粒径の分布はその質量に応じた重力が作用して、下方から順に径の大きなものから小さなものへと分布する。 In addition, in the inorganic compound storage container 12, the flow rate increases toward the upstream, and the water flow rate decreases toward the downstream. On the other hand, the inorganic compound 11 is in the form of granules having different diameters. Gravity according to the mass acts on the distribution of the diameter, and the diameter is distributed from the largest to the smallest from the bottom.
すなわち、上流ほど顆粒径の大きなものが分布するため、このことから顆粒径の大きさに比例して水流速を作用させることができ、無機化合物11の顆粒径の大小にかかわらず均一で効率のよい流動化現象が可能となる。 That is, since a thing with a larger granule diameter distributes upstream, from this, a water flow rate can be made to act in proportion to the magnitude | size of a granule diameter, and it is uniform and efficient irrespective of the magnitude | size of the granule diameter of the inorganic compound 11. A good fluidization phenomenon is possible.
さらには、無機化合物収納容器12内の無機化合物11を溶解させる水流路は、水流入側ほど面積が小さいため死水域が生じにくく、効率のよい溶解作用が可能となる。 Furthermore, since the water flow path for dissolving the inorganic compound 11 in the inorganic compound storage container 12 has a smaller area on the water inflow side, a dead water area is unlikely to occur, and an efficient dissolving action is possible.
水には粘性があるため、流水と流動化した顆粒の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。 Since water has viscosity, a velocity boundary layer is generated in the region from the surface of the inorganic compound 11 to the vicinity of the surface when passing through the porous space of flowing water and fluidized granules. FIG. 2 is a diagram showing the state of the velocity boundary layer.
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。 The flow velocity in the velocity boundary layer near the surface of the inorganic compound 11 is small, and the flow velocity passing through the center 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。 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.
上昇水流によって生ずる流動化により攪拌作用が働き、無機化合物11の表面近傍と多孔質空間の中心部の流れる水との濃度差をより大きくしながら、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効率よく溶解させることができる。 By using the principle of material diffusion while increasing the concentration difference between the vicinity of the surface of the inorganic compound 11 and the flowing water in the center of the porous space, the agitation action works due to fluidization caused by the rising water flow. Compound 11 can be efficiently dissolved in water in the porous space.
濾過手段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。 The filtering means 13 prevents the granules of the inorganic compound 11 from flowing out of the inorganic compound storage container 12 due to the water flow 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11と、内部に通水管14を有し、前記通水管14を流れる水流方向を重力方向と対向した上昇流とした無機化合物収納容器12と、濾過手段13とを備え、水回路15からの水が通水管14を流れ、その後、無
機化合物収納容器12の無機化合物11を溶解し、その溶解した無機化合物11を含んだ水が濾過手段13を通過し、再度水回路15から流出する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 storage container 12 having the inorganic compound 11 and the water flow pipe 14 therein, and the water flow direction flowing through the water flow pipe 14 as an upward flow opposite to the gravity direction, And the filtering means 13, the water from the water circuit 15 flows through the water pipe 14, and then the inorganic compound 11 in the inorganic compound storage container 12 is dissolved, and the water containing the dissolved inorganic compound 11 is filtered. The hot water supply device provided with a melting device that passes through the water circuit 15 and flows out of the water circuit 15 again.
これによって、水流方向を上昇流とすることで、流動化による攪拌効果を伴いながら、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、水に無機化合物をより効率よく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 water flow direction is changed to an upward flow, and the substance moves with the difference in dissolved concentration between water and the inorganic compound with the stirring effect due to fluidization. It is possible to dissolve the inorganic compound more efficiently. 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.
なお、本実施の形態においては、無機化合物収納容器12の無機化合物11を溶解しながら流れる水流方向を重力方向と対向した上昇流としているが、ほぼ重力方向と対向した上昇流であればよい。 In the present embodiment, the direction of water flow that flows while dissolving the inorganic compound 11 in the inorganic compound storage container 12 is an upward flow opposite to the direction of gravity, but it may be an upward flow that is substantially opposite to the direction of gravity.
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.
図3は、溶解装置の無機化合物11と濾過手段13の寸法の関係を示す例である。図3において、濾過手段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 relationship between the dimensions of the inorganic compound 11 and the filtering means 13 of the dissolving apparatus. In FIG. 3, the filtering means 13 is composed of a plurality of small holes 13a, 13b, 13c having different diameters.
図4は、濾過手段13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. 4 is a configuration example of the filtering means 13. (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16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。 The dissolution concentration flowing out of the dissolution apparatus 16 is determined by the flow rate of water passing through the inorganic compound storage container 12, the surface area of the inorganic compound 11 in contact with water, and the like. 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 inorganic compound storage container 12 of FIG. It is necessary to use the one selected for the size within the range.
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。 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.
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。 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 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.

図5は、本発明の第2の実施の形態における給湯装置の構成図を示すものである。
(Embodiment 2)
FIG. 5 shows a block diagram of a hot water supply apparatus according to the second embodiment of the present invention.
図5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、浴槽水加熱ポンプ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. 5, a heat pump unit 21 is configured by connecting a compressor 22, a hot water supply heat exchanger 23, a decompression unit 24, and an evaporator 25 in an annular manner in order by a refrigerant circuit 26. 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 bathtub water 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. ing.
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。 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.
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。 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.
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、高温の水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。 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.
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水を、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18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、貯湯タンク28の下部より内部へ流入する。 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13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。 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 13 are provided for the water circuit 15, 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.
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。 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、本発明にかかる溶解装置を備えた給湯装置は、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 including the melting device according to the present invention leads to downsizing, cost reduction, and improvement in operation efficiency, and can be used for a hot water storage hot water supply apparatus as well as a hot water supply apparatus for a gas heat source.
