It is a heater return pipe connecting the outflow side of the heater 2, and the water supplied from the water supply pipe 8 and stored in the first storage tank 4 and the second storage tank 5 is driven by a circulation pump (not shown). It flows into the heater 2 through the heater outgoing pipe 11 at the lower part of the second storage tank 5. After being heated to a high temperature, it flows through the heater return pipe 12, gradually stores hot water from the upper part of the first storage tank 4, and if the hot water tap 3 is opened, hot water is stored in the upper part of the first storage tank 4 by the supply water pressure. However, the hot water is supplied from the hot water tap 3 through the hot water supply pipe 10 at the top of the first storage tank 4.

１３は第一収容タンク４及び第二収容タンク５の外郭のほぼ全面を覆い保温・断熱を行う断熱材で、耐熱性発泡ポリスチレンからなる発泡断熱材１４と真空断熱材１５との一体成形品から構成され、型内に予め真空断熱材１５を挿入しておき、そこに発泡樹脂を流し込むことで、発泡断熱材１４のほぼ中央に真空断熱材１５が位置した成型断熱材を収容タンク４、５に合わせて複数に成型加工したものである。   Reference numeral 13 denotes a heat insulating material that covers and covers the entire outer surfaces of the first storage tank 4 and the second storage tank 5 for heat insulation and heat insulation, and is an integrally molded product of a foam heat insulating material 14 made of heat-resistant foamed polystyrene and a vacuum heat insulating material 15. It is configured, and the vacuum heat insulating material 15 is inserted in the mold in advance, and the foamed resin is poured therein, so that the molded heat insulating material in which the vacuum heat insulating material 15 is located at the approximate center of the foam heat insulating material 14 is accommodated in the storage tanks 4, 5. In accordance with the above, it is molded into multiple pieces.

上記真空断熱材１５は、芯材と、該芯材を覆うガスバリア性のラミネートフィルムからなる外被材とからなり、その内部圧力が１Ｐａ〜２００Ｐａとなるように減圧し、密閉封止したもので、公知の方法で作製出来るものである。   The vacuum heat insulating material 15 is composed of a core material and a jacket material made of a gas barrier laminate film that covers the core material, and the internal pressure is reduced to 1 Pa to 200 Pa and hermetically sealed. Can be produced by a known method.

この複数の成型断熱材は、底部断熱材１３１、前下部断熱材１３２、前上左部断熱材１３３、前上右部断熱材１３４、後部断熱材１３５、天部断熱材１３６に分割構成され、それぞれ第一収容タンク４及び第二収容タンク５に接する部分には第一収容タンク４および第二収容タンク５の外郭に沿った形状のタンク用窪部１６を有しており、これらのタンク用窪部１６を第一収容タンク４及び第二収容タンク５の外郭に密着し、それぞれ隣り合う断熱材１３同士が互いに接する面を密着して取り付けられるものである。   The plurality of molded heat insulating materials are divided into a bottom heat insulating material 131, a front lower heat insulating material 132, a front upper left heat insulating material 133, a front upper right heat insulating material 134, a rear heat insulating material 135, and a top heat insulating material 136. Each of the portions in contact with the first storage tank 4 and the second storage tank 5 has a tank recess 16 having a shape along the outline of the first storage tank 4 and the second storage tank 5. The recess 16 is brought into close contact with the outer shells of the first storage tank 4 and the second storage tank 5, and the adjacent heat insulating materials 13 are attached in close contact with each other.

このように収容タンク４、５を複数の断熱材１３で覆い、且つ真空断熱材１５が中に埋め込まれていることで、保温・断熱効果が断熱材１３自体が薄くても飛躍的に向上するものであり、製造組立時にはこの複数の断熱材１３を適切な位置にはめ込むように取り付けるだけで良く、効率的な作業を行うことができ製造組立の工数がかからずコストを抑えることができると共に、メンテナンス時の脱着作業も非常に容易になり作業性が向上するものであり、更に真空が破壊されることにより、保温・断熱効果が急激に低下する真空断熱材１５が発泡断熱材１４の中に一体成形されているので、破壊の心配がなく取り扱いも容易で安心して使用出来るものである。   As described above, the storage tanks 4 and 5 are covered with the plurality of heat insulating materials 13 and the vacuum heat insulating material 15 is embedded therein, so that the heat insulating and heat insulating effect is dramatically improved even if the heat insulating material 13 itself is thin. At the time of manufacturing and assembling, it is only necessary to attach the plurality of heat insulating materials 13 so as to be fitted at appropriate positions, so that efficient work can be performed, man-hours for manufacturing and assembly are not required, and costs can be reduced. In addition, the desorption work at the time of maintenance becomes very easy and the workability is improved, and further, the vacuum heat insulating material 15 in which the heat insulation and heat insulating effect is drastically reduced by breaking the vacuum is contained in the foam heat insulating material 14. Because it is molded integrally with the, it is easy to handle without worrying about destruction and can be used with peace of mind.

又複数の断熱材１３のそれぞれ互いに接する面には、それぞれ位置決め用の嵌合凹凸部１７を設けているので、複数の断熱材１３の位置決めが正確になると共に、複数の断熱材１３相互の密着度も高くなり複数の断熱材１３間の隙間を空気が流動することによる放熱を防ぐことができ、特に前上左部断熱材１３３と前上右部断熱材１３４と後部断熱材１３５の上面と、天部断熱材１３６の底面を嵌合凹凸部１７によって確実に密着させたことによって、垂直方向の分割面（前上左部断熱材１３３と前上右部断熱材１３４と後部断熱材１３５の互いに接する面）および水平方向の分割面（前上左部断熱材１３３と前上右部断熱材１３４と後部断熱材１３５の上面と、天部断熱材１３６の底面の接する面）の隙間の発生を確実に防ぎこの隙間やタンク用窪部１６から温度差により対流が発生して空気が流動して放熱してしまうのを確実に防止することができ、保温・断熱性能が大きく向上する。   In addition, since the positioning concave and convex portions 17 for positioning are provided on the surfaces of the plurality of heat insulating materials 13 that are in contact with each other, the positioning of the plurality of heat insulating materials 13 becomes accurate, and the heat insulating materials 13 are in close contact with each other. It is possible to prevent heat dissipation due to air flowing through the gaps between the plurality of heat insulating materials 13, and in particular, the upper surfaces of the front upper left heat insulating material 133, the front upper right heat insulating material 134, and the rear heat insulating material 135. The bottom surface of the top heat insulating material 136 is securely adhered by the fitting uneven portion 17 so that the vertical dividing surface (the front upper left heat insulating material 133, the front upper right heat insulating material 134, and the rear heat insulating material 135 Generation of gaps between the surfaces that are in contact with each other) and horizontal dividing surfaces (surfaces that are in contact with the upper surfaces of the front upper left heat insulating material 133, the front upper right heat insulating material 134, the rear heat insulating material 135, and the bottom surface of the top heat insulating material 136) To prevent this gap and Convection is generated by the temperature difference from the click for recess 16 air can be reliably prevented from being radiated by flowing, temperature-maintaining heat insulating performance is greatly improved.

又前記複数の断熱材１３の互いに接する面に、前記第一収容タンク４及び第二収容タンク５に接続された給水管８、給湯管１０等の複数の配管を収める配管用溝部１８を設けてこれら配管の保温・断熱を行っており、具体的に説明すると、前記底部断熱材１３１には、その前下部断熱材１３２または後部断熱材１３５に接する上面に前記第二収容タンク５の下部に接続された給水管８と加熱器往管１１と第一収容タンク４下部に接続されたタンク接続管９が収められる複数の配管用溝部１８が設けられ、前記後部断熱材１３５には、その前上左部断熱材１３３または前上右部断熱材１３４に接する面に第一収容タンク４と第二収容タンク５とを連通するタンク連通管９および第一収容タンク４上部に接続された加熱器復管１２が収められる複数の配管用溝部１８が設けられ、前記天部断熱材１３６には、第一収容タンク４と第二収容タンク５とを連通するタンク連通管９と第一収容タンク４上部に接続された給湯管１０が収められる複数の配管用溝部１８が設けられている。   In addition, on the surfaces of the plurality of heat insulating materials 13 that are in contact with each other, a piping groove portion 18 is provided for housing a plurality of piping such as a water supply pipe 8 and a hot water supply pipe 10 connected to the first storage tank 4 and the second storage tank 5. These pipes are insulated and insulated. Specifically, the bottom heat insulating material 131 is connected to the lower part of the second storage tank 5 on the upper surface in contact with the front lower heat insulating material 132 or the rear heat insulating material 135. There are provided a plurality of piping groove portions 18 in which the water supply pipe 8, the heater outgoing pipe 11, and the tank connection pipe 9 connected to the lower part of the first storage tank 4 are accommodated. The tank contact pipe 9 that connects the first storage tank 4 and the second storage tank 5 to the surface in contact with the left heat insulating material 133 or the front upper right heat insulating material 134 and the heater return connected to the upper part of the first storage tank 4 The tube 12 can be A pipe groove 18 is provided, and the top heat insulator 136 has a tank communication pipe 9 for communicating the first storage tank 4 and the second storage tank 5 and a hot water supply pipe connected to the upper part of the first storage tank 4. A plurality of piping grooves 18 in which 10 is accommodated are provided.

これにより、収容タンク４、５を保温・断熱するための複数の断熱材１３を適切な位置にはめ込むように取り付けるだけで、収容タンク４、５の保温・断熱だけでなく、それぞれの収容タンク４、５に接続された複数の配管８、９、１０、１１、１２も複数の断熱材１３の互いに接する面に設けられた配管用溝部１６にそれぞれはまり込んで収められて保温・断熱が行われるため、配管専用の断熱材が必要なくなると共に脱着作業も容易で作業性が良く製造組立時の工数も減りかつメンテナンス時の作業性も大幅に向上し、配管の保温・断熱にかかるコストを大幅に下げることができる。   As a result, not only the insulation and heat insulation of the storage tanks 4 and 5 but also the respective storage tanks 4 and 5 can be installed by fitting a plurality of heat insulating materials 13 for keeping and insulating the storage tanks 4 and 5 at appropriate positions. The plurality of pipes 8, 9, 10, 11, and 12 connected to 5 are also stored in the pipe groove portions 16 provided on the surfaces of the plurality of heat insulating materials 13 that are in contact with each other to perform heat insulation and heat insulation. This eliminates the need for piping-specific heat insulation, facilitates desorption work, improves workability, reduces man-hours during manufacturing and assembly, and greatly improves workability during maintenance, greatly increasing the cost of heat insulation and heat insulation for piping. Can be lowered.

この外装体１９の内面には前記複数の断熱材１３の外面の少なくとも一部が当接しており、外装体１９をしっかりと組み付けることにより前記複数の断熱材１３が内側に押しつけられて互いに接する面がより密着して保温・断熱性能が向上すると共に、タンク支持脚６、７にかかる収容タンク４、５の荷重の一部を支え、外装体１９内部での収容タンク４、５の傾き・転倒防止を行う。   At least a part of the outer surface of the plurality of heat insulating materials 13 is in contact with the inner surface of the exterior body 19, and the plurality of heat insulating materials 13 are pressed inward and firmly in contact with each other by firmly assembling the exterior body 19. Is more closely attached and heat insulation / insulation performance is improved, and a part of the load of the storage tanks 4 and 5 applied to the tank support legs 6 and 7 is supported, and the storage tanks 4 and 5 are tilted and overturned inside the exterior body 19. Prevent it.

尚、ここで前記複数の断熱材１３は、少なくとも底部断熱材と天部断熱材と前面断熱材と背面断熱材の４つに分割構成されていれば、脱着作業性よくコスト安に保温・断熱性能を向上することができるもので、メンテナンス時に取り外すことの多い前面断熱材をさらに上下に分割することで、さらにメンテナンス性を向上することができるものである。   Here, if the plurality of heat insulating materials 13 are divided into at least a bottom heat insulating material, a top heat insulating material, a front heat insulating material, and a rear heat insulating material, heat insulation and heat insulation with good desorption workability and low cost are possible. The performance can be improved, and the maintainability can be further improved by further dividing the front heat insulating material that is often removed during maintenance into upper and lower parts.

図４は前記複数の成型した断熱材１３の他の一実施形態で、断熱材１３の外周の一部を収容タンク４または５に接するタンク用窪部１６から一定厚さを残して肉抜きし、肉抜きしていない外周の一部を外装体１９内面に当接するようにしたものである。こうすることによって外装体１９をしっかりと組み付けることにより前記複数の断熱材１３が内側に押しつけられて互いに接する面がより密着して保温・断熱性能が向上すると共に、外装体１９内部での収容タンク４、５の傾き・転倒防止を行い、かつ耐熱性発泡ポリスチレンの材料コストを抑えて、さらなるコストダウンが計られる。   FIG. 4 shows another embodiment of the plurality of molded heat insulating materials 13, in which a part of the outer periphery of the heat insulating material 13 is removed from the tank recess 16 in contact with the storage tank 4 or 5 while leaving a certain thickness. In addition, a part of the outer periphery that is not thinned is brought into contact with the inner surface of the exterior body 19. In this way, by firmly assembling the exterior body 19, the plurality of heat insulating materials 13 are pressed inward so that the surfaces that come into contact with each other are more closely adhered to each other, thereby improving heat insulation and heat insulation performance. 4 and 5 are prevented from tilting and falling, and the material cost of heat-resistant foamed polystyrene is reduced, thereby further reducing the cost.

The vacuum heat insulating material 15 is not inadvertently touched by the operator's hand, and the large heat insulating effect of the vacuum heat insulating material 15 is on the storage tanks 4 and 5 side, thereby reducing the heat radiation amount and further improving the heat insulating effect. In addition, it is possible to reduce the cost by making the foam heat insulating material 14 thinner.

図６は型の外側に真空断熱材１５を寄せ、残ったところに発泡断熱材１４の樹脂を流し込み、断熱材１３の外側に真空断熱材１５が位置するようにしたものであり、これによれば、発泡断熱材１４を介しての放熱が阻止出来ると共に、外方からの冷気の侵入もシャットアウトして、更に保温・断熱効果が向上するものである。   In FIG. 6, the vacuum heat insulating material 15 is brought to the outside of the mold, and the resin of the foam heat insulating material 14 is poured into the remaining portion so that the vacuum heat insulating material 15 is located outside the heat insulating material 13. For example, heat dissipation through the foam heat insulating material 14 can be prevented, and intrusion of cold air from the outside is shut out, further improving the heat retaining and heat insulating effect.

尚、この発明はこの一実施形態に限られることなく、その要旨を変更しない範囲で他の実施形態に適用可能であるもので、例えば、ヒートポンプ式給湯機ではなく収容タンク内部に設けた電熱ヒータによって温水を作るものでも良く、また、収容タンクも一つでも良い。また、外装体を円筒型にしたものでも成型した断熱材の外周を円筒型の外装体に沿った形にすれば良いものである。   The present invention is not limited to this embodiment, and can be applied to other embodiments without changing the gist thereof. For example, an electric heater provided inside a storage tank instead of a heat pump type hot water heater. It may be used to make hot water, and there may be only one storage tank. Further, even if the outer casing is cylindrical, the outer periphery of the molded heat insulating material may be shaped along the cylindrical outer casing.
