Therefore, the work of connecting the pipes arranged around the hot water storage tank 40 can be facilitated, and the work efficiency can be improved. That is, conventionally, the pipes are fixed around the heat insulating cover by using a binding member such as a binding band to perform the connecting work, but the heat insulating cover 10 of the present embodiment has a plurality of pipe supporting portions. It is possible to stably support each pipe without using a binding member. The heat insulating cover 10 is unlikely to come off in the upward direction due to the weight of the pipes placed on the placing portions 31a to 36a.
 また、複数の配管支持部31~36の載置部は、それぞれ、上面部20と連続的に形成され、各配管の背面が接触する背面支持部と、各配管が載せられる支持側係合部と、を有している。よって、各配管の背面を2方向から支えることができるため、支持側係合部の作用と相まって、各配管をより安定的に支持することができる。 The mounting portions of the plurality of pipe supporting portions 31 to 36 are respectively formed continuously with the upper surface portion 20, and the rear surface supporting portion with which the rear surface of each pipe contacts and the supporting side engaging portion on which each pipe is mounted. And have. Therefore, since the back surface of each pipe can be supported from two directions, each pipe can be more stably supported in combination with the action of the support side engaging portion.
 加えて、複数の配管支持部31~36の載置部は、支持側係合部の下端と連続的に形成され、各配管の背面を支持する下方支持部を有している。よって、各配管の背面を3箇所で支えることにより、各配管をさらに安定的に支持することができる。もっとも、複数の配管支持部31~36には、載置部が下方支持部を有しないものがあってもよく、複数の配管支持部31~36の全ての載置部が下方支持部を有しなくてもよい。 In addition, the placement portions of the plurality of pipe support portions 31 to 36 have a lower support portion that is formed continuously with the lower end of the support side engagement portion and that supports the back surface of each pipe. Therefore, by supporting the back surface of each pipe at three points, each pipe can be supported more stably. However, among the plurality of pipe supporting portions 31 to 36, the mounting portions may not have the lower supporting portions, and all the mounting portions of the plurality of pipe supporting portions 31 to 36 may have the lower supporting portions. You don't have to.
 断熱カバー10は、側面部30の互いに対向する位置のそれぞれに、少なくとも1つの配管支持部が形成されている。本実施の形態における断熱カバー10は、配管支持部31及び32と配管支持部35及び36とが対向するように配置されている。また、配管支持部33は、配管支持部35及び36と対向するように配置されている。このようにすれば、配管によって断熱カバー10を挟み込むことができるため、断熱カバー10を安定的に支持することができる。 The heat insulating cover 10 has at least one pipe support portion formed at each of the positions of the side surface portion 30 facing each other. The heat insulating cover 10 in the present embodiment is arranged such that the pipe support portions 31 and 32 and the pipe support portions 35 and 36 face each other. Further, the pipe support portion 33 is arranged so as to face the pipe support portions 35 and 36. With this configuration, the heat insulating cover 10 can be sandwiched by the pipes, so that the heat insulating cover 10 can be stably supported.
 断熱カバー10は、配管支持部に対し配管の全体的な荷重がかかる方向を支持方向としたとき、少なくとも1つの配管支持部の支持方向と、他の少なくとも1つの配管支持部の支持方向とが、互いに交差するように構成されている。本実施の形態における断熱カバー10は、例えば、配管支持部31及び32における支持方向と、配管支持部35及び36における支持方向とが交差している。また、配管支持部33における支持方向は、配管支持部31及び32における支持方向と交差すると共に、配管支持部35及び36における支持方向とも交差している。加えて、配管支持部34における支持方向は、配管支持部31及び32における支持方向と交差すると共に、配管支持部35及び36における支持方向と交差している。 The heat insulating cover 10 has a support direction of at least one pipe support portion and a support direction of at least another pipe support portion when the direction in which the overall load of the pipe is applied to the pipe support portion is the support direction. , Are configured to intersect with each other. In the heat insulating cover 10 in the present embodiment, for example, the supporting directions of the pipe supporting portions 31 and 32 intersect with the supporting directions of the pipe supporting portions 35 and 36. The support direction of the pipe support portion 33 intersects with the support direction of the pipe support portions 31 and 32, and also intersects with the support direction of the pipe support portions 35 and 36. In addition, the support direction of the pipe support portion 34 intersects the support direction of the pipe support portions 31 and 32 and the support direction of the pipe support portions 35 and 36.
 このように、多様な支持方向が組み合わさるように複数の配管支持部を形成し、複数の配管支持部をバランスよく配置することにより、断熱カバー10の周方向の回転を抑制し、断熱カバー10をより安定的に支持することができる。すなわち、ある配管支持部の支持方向と他の配管支持部の支持方向とが互いに交差するようにし、これらの配管支持部に配管を配置することにより、断熱カバー10の固定強度を増加させることができる。なお、本実施の形態における断熱カバー10は、各配管支持部における支持方向が、それぞれ、断熱カバー10の中心部へ向かうように形成されている。 In this way, by forming a plurality of pipe supporting portions so that various supporting directions are combined and arranging the plurality of pipe supporting portions in a well-balanced manner, rotation of the heat insulating cover 10 in the circumferential direction is suppressed, and the heat insulating cover 10 is provided. Can be supported more stably. That is, the fixing strength of the heat insulating cover 10 can be increased by making the supporting direction of a certain pipe support portion and the supporting direction of another pipe support portion intersect each other and disposing the pipes in these pipe support portions. it can. In addition, the heat insulating cover 10 in the present embodiment is formed such that the supporting direction of each pipe supporting portion is toward the central portion of the heat insulating cover 10.
 断熱カバー10は、複数の配管支持部31~36のうち、2以上の配管支持部が隣接して平行に形成されている。本実施の形態の断熱カバー10は、配管支持部31と配管支持部32とが隣接して平行に形成され、配管支持部35と配管支持部36とが隣接して平行に形成されている。このようにすれば、多くの配管を貯湯タンク40の周囲に安定的に配置することができる。もっとも、本実施の形態では、2つの配管支持部が隣接して平行に形成された例を図示したが、これに限らず、断熱カバー10は、隣接して平行に形成された3つ以上の配管支持部を有していてもよい。 In the heat insulating cover 10, two or more pipe supporting portions of the plurality of pipe supporting portions 31 to 36 are formed adjacent to each other in parallel. In the heat insulating cover 10 of the present embodiment, the pipe support portion 31 and the pipe support portion 32 are formed adjacent to each other in parallel, and the pipe support portion 35 and the pipe support portion 36 are formed adjacent to each other in parallel. With this configuration, many pipes can be stably arranged around the hot water storage tank 40. However, in the present embodiment, an example in which two pipe support portions are formed adjacent to each other in parallel is shown, but the present invention is not limited to this, and the heat insulating cover 10 includes three or more adjacent pipe formation portions formed in parallel. You may have a piping support part.
 タンクユニット50の複数の配管は、それぞれ、側面が側面支持部に接触するように配置される上端部4aと、上端部4aの下端に接続され、載置部に接触するように配置される配管側係合部4bと、を有している。すなわち、タンクユニット50の複数の配管は、それぞれ、上部が屈曲しており、その屈曲形状に合わせて各配管支持部が掘られている。したがって、各配管は各配管支持部によって安定的に支持される。 The plurality of pipes of the tank unit 50 are respectively connected to the upper end portion 4a whose side surface is in contact with the side surface support portion and the lower end of the upper end portion 4a, and are arranged so as to be in contact with the mounting portion. And a side engaging portion 4b. That is, the upper portions of the plurality of pipes of the tank unit 50 are bent, and the pipe support portions are dug in accordance with the bent shape. Therefore, each pipe is stably supported by each pipe support portion.
 また、断熱カバー10の複数の配管支持部31~36は、それぞれ、各配管の上端部4aと配管側係合部4bとによる屈曲形状に合わせた形状となっている。そして、貯湯タンク40の周囲に配置される複数の配管の各々の屈曲形状は、互いに異なっている。したがって、各配管と各配管支持部との対応関係を一見して把握することができるため、どの配管をどの配管支持部に配置するかを容易に見分けることができる。すなわち、タンクユニット50の組み立ての際、配管の上部と、断熱カバー10に形成されている配管支持部の形状とを見比べることにより、各配管を簡単に正しい位置へ配置することができる。 Further, the plurality of pipe supporting portions 31 to 36 of the heat insulating cover 10 are shaped according to the bent shape of the upper end portion 4a of each pipe and the pipe side engaging portion 4b. The bent shapes of the plurality of pipes arranged around the hot water storage tank 40 are different from each other. Therefore, since the correspondence between each pipe and each pipe support can be grasped at a glance, which pipe is to be arranged in which pipe support can be easily identified. That is, at the time of assembling the tank unit 50, by comparing the upper portion of the pipe with the shape of the pipe support portion formed on the heat insulating cover 10, each pipe can be easily arranged at the correct position.
 さらに、配管2aは、2つの上端部4aを有しており、これら2つの上端部4aは、配管側係合部4bによって連結されている。したがって、配管2aは、配管支持部33に載せた状態において、主管2mの上端部4aが、背面支持部33hy、下方支持部33n、及び側面支持部33bに支持され、分岐管2nの上端部4aが、背面支持部33hx及び側面支持部33bに支持される。加えて、配管2aは、配管側係合部4bが支持側係合部33kに係合する。よって、配管2aは、配管支持部33によって安定的に支持することができる。なお、上記実施の形態では、2つの上端部4aを有する配管として配管2aのみを例示したが、これに限らず、タンクユニット50は、2つの上端部4aを有する複数の配管を有していてもよい。 Furthermore, the pipe 2a has two upper end portions 4a, and these two upper end portions 4a are connected by a pipe side engaging portion 4b. Therefore, when the pipe 2a is placed on the pipe support portion 33, the upper end portion 4a of the main pipe 2m is supported by the rear surface support portion 33hy, the lower support portion 33n, and the side surface support portion 33b, and the upper end portion 4a of the branch pipe 2n. Are supported by the back surface support portion 33hx and the side surface support portion 33b. In addition, in the pipe 2a, the pipe side engaging portion 4b engages with the support side engaging portion 33k. Therefore, the pipe 2a can be stably supported by the pipe support portion 33. In the above embodiment, only the pipe 2a is illustrated as the pipe having the two upper end portions 4a, but the present invention is not limited to this, and the tank unit 50 has a plurality of pipes having the two upper end portions 4a. Good.
 さらに、タンクユニット50において、複数の配管のうちの少なくとも1つは、下端が貯湯タンク40の側面に接続されている。本実施の形態では、配管2aの下端のうちの一方と、配管2bの下端のうちの一方とが、貯湯タンク40の側面に接続されている。そして、配管2a及び配管2bは、貯湯タンク40の側面に沿って上方向に伸びており、上部が配管支持部によって支持されている。したがって、特許文献1の断熱カバーのように、複数の配管をまとめて通過させる大きな開口部を中央部に設ける必要がない。つまり、断熱カバーを発砲断熱材と蓋部材とに分けて作成する必要がないため、本実施の形態の構成を採れば、断熱カバーの形成が容易となる。 Further, in the tank unit 50, the lower end of at least one of the plurality of pipes is connected to the side surface of the hot water storage tank 40. In the present embodiment, one of the lower ends of pipe 2a and one of the lower ends of pipe 2b are connected to the side surface of hot water storage tank 40. The pipes 2a and 2b extend upward along the side surface of the hot water storage tank 40, and the upper portions thereof are supported by the pipe support portion. Therefore, unlike the heat insulating cover of Patent Document 1, it is not necessary to provide a large opening in the central portion for passing a plurality of pipes together. That is, since it is not necessary to separately form the heat insulating cover into the foam heat insulating material and the lid member, the heat insulating cover can be easily formed by adopting the configuration of the present embodiment.
 上記の実施の形態は、断熱カバー及びタンクユニットにおける好適な具体例であり、本発明の技術的範囲は、これらの態様に限定されるものではない。例えば、上記の実施の形態では、貯湯タンク40の周囲に6本の配管が配置される例を示したが、これに限定されない。タンクユニット50において、貯湯タンク40の周囲に配置される配管は、2本以上5本以下であってもよく、7本以上であってもよい。加えて、配管支持部の形状は、各図に例示した形状に限らず、各配管の上部形状に合わせて適宜変更することができる。ただし、配管支持部は、載置部と側面支持部とを有するように構成する。 The above embodiment is a preferred specific example of the heat insulating cover and the tank unit, and the technical scope of the present invention is not limited to these aspects. For example, in the above embodiment, an example in which six pipes are arranged around the hot water storage tank 40 has been shown, but the present invention is not limited to this. In the tank unit 50, the number of pipes arranged around the hot water storage tank 40 may be 2 or more and 5 or less, or 7 or more. In addition, the shape of the pipe support portion is not limited to the shape illustrated in each drawing, and can be appropriately changed according to the upper shape of each pipe. However, the pipe support portion is configured to have a mounting portion and a side surface support portion.
 また、図1では、配管2bの下端のうちの一方が貯湯タンク40の側面に直接的に接続された例を示したが、これに限らず、配管2bの下端のうちの一方は、別に設けられた冷媒回路等の熱交換器を介して貯湯タンク40の側面に接続されてもよい。配管2aの下端のうちの一方も同様、別に設けられた冷媒回路等の熱交換器を介して貯湯タンク40の側面に接続されてもよい。なお、ブライン回路80を循環させる熱媒体として、水などのブライン以外の熱媒体を採用してもよい。 Further, FIG. 1 shows an example in which one of the lower ends of the pipe 2b is directly connected to the side surface of the hot water storage tank 40, but the present invention is not limited to this, and one of the lower ends of the pipe 2b is provided separately. It may be connected to the side surface of the hot water storage tank 40 via a heat exchanger such as a provided refrigerant circuit. Similarly, one of the lower ends of the pipe 2a may be connected to the side surface of the hot water storage tank 40 via a heat exchanger such as a separately provided refrigerant circuit. A heat medium other than brine, such as water, may be used as the heat medium for circulating the brine circuit 80.
