Description

この発明は、タンク断熱構造および貯湯タンク装置に関し、特に貯湯タンクを断熱するタンク断熱構造およびそれを用いた貯湯タンク装置に関する。   The present invention relates to a tank heat insulating structure and a hot water storage tank apparatus, and more particularly to a tank heat insulating structure for insulating a hot water storage tank and a hot water storage tank apparatus using the same.

従来、タンク断熱構造としては、２つの貯湯タンクを成形断熱材により覆ったものがある(例えば、特開２０１０−１１２６０８号公報(特許文献１)参照)。上記タンク断熱構造では、２つの貯湯タンクを成形断熱材により覆うことにより貯湯タンクからの熱の放散を防止している。   Conventionally, as a tank heat insulating structure, there is one in which two hot water storage tanks are covered with a molded heat insulating material (for example, see JP 2010-112608 A (Patent Document 1)). In the tank heat insulating structure, heat dissipation from the hot water storage tank is prevented by covering the two hot water storage tanks with the molded heat insulating material.

ところで、上記タンク断熱構造では、２つの貯湯タンクを覆う複数の成形断熱材のうち、２つの貯湯タンクの側方を挟むように覆う断面Ｗ字形状の成形断熱材のサイズが大きいため、製造段階において多数の断面Ｗ字形状の成形断熱材を保管する場合は、互いに重ね合わせても、広い置き場スペースが必要となるという問題がある。   By the way, in the said tank heat insulation structure, since the size of the shaping | molding heat insulating material of the W-shaped cross section which covers so that the side of two hot water storage tanks may be pinched | interposed among the some shaping | molding heat insulating materials which cover two hot water storage tanks, it is a manufacturing stage. In the case of storing a large number of molded heat insulating materials having a W-shaped cross section, there is a problem that a large storage space is required even if they are superposed on each other.

特開２０１０−１１２６０８号公報JP 2010-112608 A

そこで、この発明の課題は、断熱部材の置き場スペースを小さくできるタンク断熱構造および貯湯タンク装置を提供することにある。   Then, the subject of this invention is providing the tank heat insulation structure and hot water storage tank apparatus which can make the storage space of a heat insulation member small.

上記課題を解決するため、この発明のタンク断熱構造は、
互いに略平行に配置された第１,第２のタンクを断熱するためのタンク断熱構造であって、
上記第１のタンクを周方向に覆う断面半円弧形状の第１,第２成形断熱材と、
上記第２のタンクを周方向に覆う断面半円弧形状の第３,第４成形断熱材と
備え、
上記第１,第３成形断熱材を上記第１,第２のタンクと上記第２,第４成形断熱材により上記第１,第２のタンク間に周方向に押さえ込むことを特徴とする。 In order to solve the above problems, the tank heat insulating structure of the present invention is
A tank heat insulating structure for insulating the first and second tanks arranged substantially parallel to each other,
First and second shaped heat insulating materials having a semicircular cross-sectional shape covering the first tank in the circumferential direction;
A third and fourth molded heat insulating material having a semicircular cross-sectional shape covering the second tank in the circumferential direction;
The first and third molded heat insulating materials are pressed in the circumferential direction between the first and second tanks by the first and second tanks and the second and fourth molded heat insulating materials.

上記構成によれば、第１,第３成形断熱材を第１,第２のタンクと第２,第４成形断熱材により上記第１,第２のタンク間に周方向に押さえ込むことによって、第１〜第４成形断熱材が第１,第２のタンクの夫々の外周の半分を囲む大きさであるため、互いに重ね合わせることで、断熱部材の置き場スペースを小さくできる。また、組立時に第１〜第４成形断熱材が広がらないので、作業性を向上できる。   According to the above configuration, the first and third molded heat insulating materials are pressed between the first and second tanks in the circumferential direction by the first and second tanks and the second and fourth molded heat insulating materials. Since the 1st-4th shaping | molding heat insulating material is a magnitude | size surrounding the half of each outer periphery of a 1st, 2nd tank, the storage space of a heat insulation member can be made small by overlapping each other. Moreover, since the 1st-4th shaping | molding heat insulating material does not spread at the time of an assembly, workability | operativity can be improved.

また、一実施形態のタンク断熱構造では、
上記第１成形断熱材と上記第３成形断熱材は、上記第１,第２のタンク間の中間点を中心に点対象に配置されると共に、上記第２成形断熱材と上記第４成形断熱材は、上記第１,第２のタンク間の中間点を中心に点対象に配置されており、
上記第１,第３成形断熱材の断面半円弧形状の一端に、径方向外側に突出する凸部が夫々設けられ、
上記第２,第４成形断熱材の断面半円弧形状の一端は、上記第１,第３成形断熱材の上記凸部に対して周方向に係合している。 Moreover, in the tank heat insulation structure of one embodiment,

The material is arranged to be pointed around the midpoint between the first and second tanks,
Convex portions protruding radially outward are provided at one ends of the semicircular arc sections of the first and third molded heat insulating materials,
One end of the semicircular arc shape of the cross section of the second and fourth molded heat insulating materials is engaged in the circumferential direction with the convex portion of the first and third molded heat insulating materials.

上記実施形態によれば、第１,第３成形断熱材の断面半円弧形状の一端に、径方向外側に突出するように設けられた凸部に対して、第２,第４成形断熱材の断面半円弧形状の一端が周方向に係合することによって、第１,第３成形断熱材の一端と第２,第４成形断熱材の一端とを固定することが可能になる。また、第１,第２成形断熱材を同一形状の部材とし、第３,第４成形断熱材を同一形状の部材とすることが可能となり、４つの成形断熱部材を２種類で実現でき、部品点数を低減できる。   According to the above-described embodiment, the second and fourth molded heat insulating materials are formed at one end of the semicircular cross-sectional shape of the first and third molded heat insulating materials with respect to the convex portion provided so as to protrude radially outward. By engaging one end of the semicircular cross-sectional shape in the circumferential direction, it is possible to fix one end of the first and third molded heat insulating materials and one end of the second and fourth molded heat insulating materials. In addition, the first and second molded heat insulating materials can be made the same shape member, and the third and fourth molded heat insulating materials can be made the same shape member. The score can be reduced.

また、一実施形態のタンク断熱構造では、
上記第１成形断熱材の断面半円弧形状の他端が上記第２成形断熱材の断面半円弧形状の他端に径方向に係合すると共に、
上記第３成形断熱材の断面半円弧形状の他端が上記第４成形断熱材の断面半円弧形状の他端に径方向に係合している。 Moreover, in the tank heat insulation structure of one embodiment,
The other end of the semicircular arc shape of the first molded heat insulating material engages the other end of the semicircular arc shape of the second molded heat insulating material in the radial direction,
The other end of the semicircular cross-sectional shape of the third shaped heat insulating material is radially engaged with the other end of the semicircular cross sectional shape of the fourth shaped heat insulating material.

上記実施形態によれば、第１成形断熱材の断面半円弧形状の他端が第２成形断熱材の断面半円弧形状の他端に径方向に係合することによって、第１成形断熱材の断面半円弧形状の他端と第２成形断熱材の断面半円弧形状の他端とを隙間なく固定することが可能になる。同様に、第３成形断熱材の断面半円弧形状の他端が第４成形断熱材の断面半円弧形状の他端に径方向に係合することによって、第３成形断熱材の断面半円弧形状の他端と第４成形断熱材の断面半円弧形状の他端とを隙間なく固定することが可能になる。したがって、第１,第２のタンクの側方に対する断熱性能を高めることができる。   According to the embodiment, the other end of the semi-circular cross-sectional shape of the first molded heat insulating material is engaged with the other end of the semi-circular cross-sectional shape of the second formed heat insulating material in the radial direction. It becomes possible to fix the other end of the semicircular cross section and the other end of the semicircular cross section of the second shaped heat insulating material without any gap. Similarly, the cross-sectional semicircular arc shape of the third molded heat insulating material is obtained by engaging the other end of the semicircular arc shape of the third molded heat insulating material in the radial direction with the other end of the semicircular cross sectional shape of the fourth molded heat insulating material. It is possible to fix the other end of the fourth molded heat insulating material and the other end of the fourth semi-circular heat insulating material without a gap. Therefore, the heat insulation performance with respect to the sides of the first and second tanks can be enhanced.

図１０は上記断熱構造体の第２,第３成型断熱材２２,２３(図１０ではＡ,Ｂ)の置き場スペースを説明するための図を示している。図１０において、成型断熱材Ａ,Ｂを置き場スペースに立設させて保管するとき、成型断熱材Ａ,Ｂを４５°毎に回転させながら重ね合わせる。これにより、成型断熱材Ａ,Ｂ(合計８個)を、点線で示す円で表された最小限のスペースに置くことができる。   FIG. 10 is a view for explaining the storage space for the second and third molded heat insulating materials 22 and 23 (A and B in FIG. 10) of the heat insulating structure. In FIG. 10, when the molded heat insulating materials A and B are stood and stored in the storage space, the molded heat insulating materials A and B are overlapped while being rotated every 45 °. As a result, the molded heat insulating materials A and B (a total of eight) can be placed in a minimum space represented by a circle indicated by a dotted line.

これに対して、図１１は比較例の断熱構造体の水平断面図を示している。なお、この比較例は、比較のために説明するものであって、この発明のタンク断熱構造ではない。図１１では、２つの貯湯タンク(図示せず)の側方を、断面半円弧形状が２つ連結された成形断熱材１０１,１０２(図１１ではＷ)により挟むように覆っている。   On the other hand, FIG. 11 shows a horizontal sectional view of a heat insulating structure of a comparative example.
