These are sectional drawings which show roughly the BB cross section of a heat exchange part in the hot water supply heat exchanger of FIG.

本発明の熱交換部１００は、一例として、１３個の隔板１０１〜１１３が重なった構造よりなる。前記隔板１０１〜１１３は、暖房水と直水の熱交換が行われる電熱面になるものであって、薄板の端部を折り曲げて、隣合う隔板１０１〜１１３の端部を互いに溶接結合することによって、積層構造を形成するようになる。   The heat exchange part 100 of this invention consists of a structure with which 13 partition plates 101-113 overlapped as an example. The partition plates 101 to 113 serve as an electric heating surface where heat exchange between the heating water and direct water is performed. The end portions of the thin plates are bent and the end portions of the adjacent partition plates 101 to 113 are welded to each other. By doing so, a laminated structure is formed.

前記隔板１０２〜１１２には、電熱面積の拡大のために凹凸が形成されている。図４と図５では、前記凹凸の図示が省略されている。   The partition plates 102 to 112 are formed with irregularities to increase the electric heating area. In FIG. 4 and FIG. 5, illustration of the unevenness is omitted.

前記隔板１０２〜１１２には、暖房水と温水が互いに混合されず、熱交換部１００の内部で流動が可能となるように、暖房水通過孔１０１ａ〜１１２ａ、１０２ｂ〜１１１ｂと直水通過孔１０１ｃ〜１１２ｃ、１０３ｄ〜１１２ｄが形成されている。   Heating water passage holes 101a to 112a, 102b to 111b and direct water passage holes are provided in the partition plates 102 to 112 so that the heating water and the hot water are not mixed with each other and can flow inside the heat exchange unit 100. 101c to 112c and 103d to 112d are formed.

前記暖房水通過孔１０１ａ〜１１２ａ、１０２ｂ〜１１１ｂと直水通過孔１０１ｃ〜１１２ｃ、１０３ｄ〜１１２ｄは、隔板１０１〜１１３の平たい部分を突出させると同時に、フランジが形成されるように折り曲げた形状よりなり、隣合う隔板の暖房水通過孔と直水通過孔を相互連通するように結合することが可能である。
図４と図５に示されたように、隣合う隔板にそれぞれ暖房水通過孔と直水通過孔の周りを突出したフランジ形状で形成することによって構成することもでき、１つの隔板には、孔だけを形成し、その隣合う隔板には、孔を突出するようにして、フランジが形成されるようにするもので構成することもできる。 The heating water passage holes 101a to 112a, 102b to 111b and the direct water passage holes 101c to 112c and 103d to 112d are bent so that a flat portion of the partition plates 101 to 113 protrudes and at the same time a flange is formed. It is possible to connect the heating water passage hole and the direct water passage hole of the adjacent partition plates so as to communicate with each other.
As shown in FIG. 4 and FIG. 5, it can also be configured by forming flanges projecting around the heating water passage hole and the direct water passage hole in adjacent partition plates, respectively. Can be configured by forming only a hole and projecting the hole on the adjacent partition so that a flange is formed.

このように連結された暖房水通過孔１０１ａ〜１１２ａ、１０２ｂ〜１１１ｂは、暖房水が流れる経路を形成し、直水通過孔１０１ｃ〜１１２ｃ、１０３ｄ〜１１２ｄは、直水が流れる経路を形成するようになる。   The heating water passage holes 101a to 112a and 102b to 111b connected in this way form a path through which the heating water flows, and the direct water passage holes 101c to 112c and 103d to 112d form a path through which the direct water flows. become.

前記隔板１０１〜１１３の間に形成された空間は、図４と図５に示されたように、暖房水循環経路１３１、１３２と直水循環経路１３３、１３４を形成する。第１アダプタ２１０を通じて熱交換部１００の内部に流入された暖房水は、第１暖房水循環経路１３１及び第２暖房水循環経路１３２を順次通過しながら第１直水循環経路１３３及び第２直水循環経路１３４を通過する直水と熱交換が行われた後、第１アダプタ２１０を通じて暖房還水側に排出される。
また、第２アダプタ２２０を通じて熱交換部１００の内部に流入された直水は、第１直水循環経路１３３及び第２直水循環経路１３４を順に通過しながら第１暖房水循環経路１３１及び第２暖房水循環経路１３２を通過する暖房水と熱交換が行われた後、第２アダプタ２２０を通じて温水所要先に供給される。 The space formed between the partition plates 101 to 113 forms heating water circulation paths 131 and 132 and direct water circulation paths 133 and 134, as shown in FIGS. The heating water that has flowed into the heat exchanging unit 100 through the first adapter 210 passes through the first heating water circulation path 131 and the second heating water circulation path 132 in order, and then the first straight water circulation path 133 and the second straight water circulation path 134. After the heat exchange with the direct water passing through, the water is discharged through the first adapter 210 to the heating return water side.
Further, the direct water that has flowed into the heat exchanging unit 100 through the second adapter 220 passes through the first straight water circulation path 133 and the second straight water circulation path 134 in order, and then the first heating water circulation path 131 and the second heating water circulation. After the heat exchange with the heating water passing through the path 132 is performed, it is supplied to the required hot water destination through the second adapter 220.

前記アダプタ２１０、２２０が結合される隔板１０１には、熱交換部１００の外側方向に突出するように対角線方向に横切る形状の暖房水通過部１０１ｅが形成されている。前記暖房水通過部１０１ｅが形成された隔板１０１とそれに隣接する隔板１０２との間の空間は、第１暖房水循環経路１３１を形成するようになる。前記隔板１０２の表面には、凹凸が形成され、この場合、一番目の隔板１０１において暖房水通過部１０１ｅが形成された部分を除いた残りの平板部分は、隣合う隔板１０２に形成された凹凸と接触するか、または距離が非常に細くなるので、暖房水がこの部分を通過するとき、流路抵抗を大きく作用させることができる。
本発明の場合、外側方向に突出するように暖房水通過部１０１ｅを形成し、前記暖房水通過部１０１ｅの一端部に暖房水が流入される暖房水通過孔１０１ａが形成されるようにして、前記暖房水を、流路が拡張された暖房水通過部１０１ｅに誘導することによって、暖房水が通過するとき、流路抵抗を少なく作用させる。 The partition plate 101 to which the adapters 210 and 220 are coupled is formed with a heating water passage portion 101e having a shape that crosses in a diagonal direction so as to protrude outward of the heat exchange portion 100. A space between the partition plate 101 where the heating water passage portion 101e is formed and the partition plate 102 adjacent thereto forms a first heating water circulation path 131. Concavities and convexities are formed on the surface of the partition plate 102. In this case, the remaining flat plate portion of the first partition plate 101 excluding the portion where the heating water passage portion 101e is formed is formed on the adjacent partition plate 102. Since the contact is made with the unevenness or the distance becomes very small, when the heating water passes through this portion, the flow resistance can be greatly affected.
In the case of the present invention, the heating water passage portion 101e is formed so as to protrude outward, and the heating water passage hole 101a into which the heating water flows into one end of the heating water passage portion 101e is formed, When the heating water passes by guiding the heating water to the heating water passage portion 101e with the expanded flow path, the flow path resistance is reduced.

一方、一番目の隔板１０１に対向する熱交換部１００の他側に設けられた隔板１１３には、熱交換部１００の外側方向に突出するように対角線方向に横切る形状の直水通過部１１３ｅが形成されている。前記直水通過部１１３ｅが形成された隔板１１３とそれに隣接する隔板１１２との間の空間は、第１直水循環経路１３３を形成するようになる。前記直水通過部１１３ｅによって流路が拡張されることによって、直水が第１直水循環経路１３３を通過するとき、受ける流路抵抗を少なくする。   On the other hand, the partition plate 113 provided on the other side of the heat exchange unit 100 facing the first partition plate 101 has a straight water passage portion having a shape that crosses in a diagonal direction so as to protrude outward of the heat exchange unit 100. 113e is formed. A space between the partition plate 113 in which the direct water passage portion 113e is formed and the partition plate 112 adjacent to the partition plate 113 forms a first straight water circulation path 133. The flow path is expanded by the direct water passage portion 113e, so that the flow path resistance received when the direct water passes through the first straight water circulation path 133 is reduced.

The straight water that has flowed into the inlet 221 passes through the internal connector 223 and the fourth connection member 242, and is formed on the opposite side surface where the adapters 210 and 220 of the heat exchange unit 100 are coupled. It flows into the water circulation path 133.

前記第１直水循環経路１３３に流入された直水は、水平方向に流れた後、隔板１１１、１１２に形成された直水通過孔１１１ｄ、１１２ｄを通じて下側の直水循環経路に流入される。   The direct water that has flowed into the first straight water circulation path 133 flows in the horizontal direction, and then flows into the lower straight water circulation path through the straight water passage holes 111 d and 112 d formed in the partition plates 111 and 112.

前記第１直水循環経路１３３を形成する隔板１１３には、流路断面積が拡張された直水通過部１１３ｅが形成されていて、前記第１直水循環経路１３３を通過する直水には、流路抵抗が大きく作用しない。   The partition plate 113 forming the first straight water circulation path 133 is formed with a straight water passage portion 113e having an expanded flow path cross-sectional area, and the direct water passing through the first straight water circulation path 133 is The channel resistance does not work greatly.

前記通過孔１１１ｄ、１１２ｄを通過した暖房水は、その直下方に形成された他の隔板の直水通過孔１１０ｄ〜１０３ｄを順次通過した後、前記第１直水循環経路１３３の下部に形成された複数の第２直水循環経路１３４を通じて前記第１直水循環経路１３３での流れ方向と反対方向である水平方向に流れるようになる。   The heating water that has passed through the passage holes 111d and 112d is formed in the lower part of the first straight water circulation path 133 after sequentially passing through the direct water passage holes 110d to 103d of other partition plates formed immediately below the passage holes 111d and 112d. In addition, it flows in a horizontal direction that is opposite to the flow direction in the first straight water circulation path 133 through the plurality of second straight water circulation paths 134.

前記第２直水循環経路１３４を通過しながら暖房水循環経路１３１、１３２を通過する暖房水と熱交換が行われた直水は、前記直水通過孔１１０ｄ〜１０３ｄの対角線水平方向に形成された直水通過孔１１０ｃ〜１０３ｃを順次に通過した後、第３連結部材２４１と第４連結部材２４２との間の空間２４１ａに流入され、内部連結具２２３と外部連結具２２４との間の空間２２５を順次通過しながら温水になった状態で排出口２２２を通じて温水所要先側に排出される。   The direct water that has undergone heat exchange with the heating water passing through the heating water circulation paths 131 and 132 while passing through the second straight water circulation path 134 is formed directly in the diagonal horizontal direction of the direct water passage holes 110d to 103d. After sequentially passing through the water passage holes 110c to 110c, the water is introduced into the space 241a between the third connection member 241 and the fourth connection member 242, and the space 225 between the internal connection tool 223 and the external connection tool 224 is passed through. The hot water is discharged through the discharge port 222 to the required hot water side while being sequentially passed.

この場合、前記直水通過孔１１０ｃ〜１０３ｃには、第４連結部材２４２が挿入されていて、第４連結部材２４２の外周面と前記直水通過孔１１０ｃ〜１０３ｃとの間に形成された隙間を通じて直水が流動するようになる。   In this case, a fourth connection member 242 is inserted into the direct water passage holes 110c to 103c, and a gap formed between the outer peripheral surface of the fourth connection member 242 and the direct water passage holes 110c to 103c. Direct water will flow through.

上記のように、本発明は、１つの第１暖房水循環経路１３１、複数の第２直水循環経路１３４、複数の第２暖房水循環経路１３２及び１つの第１直水循環経路１３３が順次に積層形成されていて、熱交換部１００の内部を流動する暖房水と直水の流動経路が短いため、流路抵抗を少なくすることができる。   As described above, in the present invention, one first heating water circulation path 131, a plurality of second straight water circulation paths 134, a plurality of second heating water circulation paths 132, and a first first water circulation path 133 are sequentially stacked. In addition, since the flow path of the heating water and the direct water flowing inside the heat exchanging unit 100 is short, the flow path resistance can be reduced.

すなわち、暖房水が熱交換部１００の内部に流入される一番目の空間である第１暖房水循環経路１３１と直水が熱交換部１００の内部に流入される一番目の空間である第１直水循環経路１３３が、熱交換部１００の一側及び他側にそれぞれ形成されているので、暖房水と直水の流動経路を短縮させることができる。   That is, the first heating water circulation path 131 that is the first space in which the heating water flows into the heat exchange unit 100 and the first space that is the first space in which the direct water flows into the heat exchange unit 100. Since the water circulation path 133 is formed on one side and the other side of the heat exchanging unit 100, the flow paths of the heating water and the direct water can be shortened.

なお、三方弁３０が暖房モードに転換されれば、暖房所要先に供給された暖房水は、熱交換過程が行われた後、循環ポンプ１０側に還水される。本発明では、循環ポンプ１０側に還水される暖房還水を第１アダプタ２１０の暖房還水連結具２１７に流入させて、排出口２１２を経て、膨脹タンク５０を通じて循環ポンプ１０側に還水される。   If the three-way valve 30 is switched to the heating mode, the heating water supplied to the heating required destination is returned to the circulation pump 10 side after the heat exchange process is performed. In the present invention, heating return water returned to the circulation pump 10 side is caused to flow into the heating return water connector 217 of the first adapter 210, and returned to the circulation pump 10 side through the expansion tank 50 through the discharge port 212. Is done.

もし暖房配管の内部に暖房水が不足な場合、給水弁３００を開放させて、暖房水を補う。給水弁３００は、第１アダプタ２１０の給水弁連結具２１６と第２アダプタ２２０の給水弁連結具２２６との間に設置される。したがって、給水弁３００を開放させれば、第２アダプタ２２０の内部の温水のうち一部が給水弁連結具２２６を通じて第１アダプタ２１０の給水弁連結具２１６と排出口２１２を順次経由した後、還水側の暖房配管に供給される。   If the heating water is insufficient inside the heating pipe, the water supply valve 300 is opened to supplement the heating water. The water supply valve 300 is installed between the water supply valve connector 216 of the first adapter 210 and the water supply valve connector 226 of the second adapter 220. Accordingly, if the water supply valve 300 is opened, a part of the hot water inside the second adapter 220 sequentially passes through the water supply valve connector 216 and the discharge port 212 of the first adapter 210 through the water supply valve connector 226. It is supplied to the heating pipe on the return water side.
