実施の形態１．
図１は、実施の形態１による貯湯式給湯機用断熱材が貯湯タンク１に組み付けられた状態を示す正面図である。図２は、実施の形態１による貯湯式給湯機用断熱材が貯湯タンク１に組み付けられた状態を示す側面図である。 Embodiment 1.
FIG. 1 is a front view showing a state in which the heat insulating material for a hot water storage type water heater according to the first embodiment is assembled to the hot water storage tank 1. FIG. 2 is a side view showing a state in which the heat insulating material for a hot water storage type water heater according to the first embodiment is assembled to the hot water storage tank 1.

貯湯タンク１は、貯湯式給湯機に備えられ、湯を貯留する。貯湯タンク１は、例えばステンレス鋼のような金属で作られている。図示の例の貯湯タンク１は、円筒状の外形を有する。貯湯式給湯機が据え付けられると、貯湯タンク１の中心軸は鉛直線に平行になる。以下の説明では、原則として、貯湯タンク１の中心軸が鉛直線に平行となった状態を基準として方向を特定する。 The hot water storage tank 1 is provided in a hot water storage type water heater and stores hot water. The hot water storage tank 1 is made of a metal such as stainless steel. The hot water storage tank 1 of the illustrated example has a cylindrical outer shape. When the hot water storage type water heater is installed, the central axis of the hot water storage tank 1 becomes parallel to the vertical line. In the following description, as a general rule, the direction is specified based on the state in which the central axis of the hot water storage tank 1 is parallel to the vertical line.

貯湯式給湯機用断熱材は、貯湯タンク１を保温するために貯湯タンク１の外側に配置される。貯湯式給湯機用断熱材は、複数の断熱材を含む。図示の例の貯湯式給湯機用断熱材は、断熱材２及び断熱材３を含む。図示の例では、断熱材２が貯湯タンク１の胴部の正面側の約半周を覆う。断熱材３が貯湯タンク１の胴部の背面側の約半周を覆う。図１及び図２では、貯湯タンク１の上部を形成する上鏡板を覆う断熱材と、貯湯タンク１の下部を形成する下鏡板を覆う断熱材との図示が省略されているが、貯湯式給湯機においてはそれらの断熱材がさらに配置される。 The heat insulating material for a hot water storage type water heater is arranged outside the hot water storage tank 1 in order to keep the hot water storage tank 1 warm. The heat insulating material for a hot water storage type water heater includes a plurality of heat insulating materials. The heat insulating material for a hot water storage type water heater in the illustrated example includes a heat insulating material 2 and a heat insulating material 3. In the illustrated example, the heat insulating material 2 covers about half a circumference on the front side of the body of the hot water storage tank 1. The heat insulating material 3 covers about half a circumference on the back side of the body of the hot water storage tank 1. In FIGS. 1 and 2, the heat insulating material covering the upper end plate forming the upper part of the hot water storage tank 1 and the heat insulating material covering the lower end plate forming the lower part of the hot water storage tank 1 are not shown, but the hot water storage type hot water supply type. In the machine, those heat insulating materials are further arranged.

各断熱材が配置される個所は、図示の例に限定されない。例えば、断熱材２が貯湯タンク１の胴部の左側の約半周を覆い、断熱材３が貯湯タンク１の胴部の右側の約半周を覆ってもよい。また、本開示の貯湯式給湯機用断熱材は、貯湯タンク１の上部あるいは下部を覆う断熱材を含んでもよい。また、貯湯タンク１と、本開示の貯湯式給湯機用断熱材との間に、例えば真空断熱材のような別の断熱材を配置してもよい。 The place where each heat insulating material is arranged is not limited to the illustrated example. For example, the heat insulating material 2 may cover about half the circumference on the left side of the body of the hot water storage tank 1, and the heat insulating material 3 may cover about half the circumference on the right side of the body of the hot water storage tank 1. Further, the heat insulating material for a hot water storage type water heater of the present disclosure may include a heat insulating material covering the upper part or the lower part of the hot water storage tank 1. Further, another heat insulating material such as a vacuum heat insulating material may be arranged between the hot water storage tank 1 and the heat insulating material for the hot water storage type water heater of the present disclosure.

図３は、断熱材２の正面図である。図３に示すように、断熱材２は、貯湯タンク１に向かい合う面とは反対側の面から突出する突出部２ａを有する。貯湯式給湯機においては、機器が突出部２ａに対して取り付けられる。突出部２ａに取り付けられる機器は、例えば、熱交換器、ポンプ、バルブ、配管、制御基板のうちの少なくとも一つでもよい。形状が異なる複数種類の断熱材２が存在し、貯湯式給湯機の機種に応じて、異なる種類の断熱材２が使用される。例えば、貯湯式給湯機の機種に応じて、鉛直方向あるいは水平方向についての突出部２ａの位置が異なる断熱材２が用いられる。 FIG. 3 is a front view of the heat insulating material 2. As shown in FIG. 3, the heat insulating material 2 has a protruding portion 2a protruding from a surface opposite to the surface facing the hot water storage tank 1. In the hot water storage type water heater, the device is attached to the protrusion 2a. The device attached to the protrusion 2a may be, for example, at least one of a heat exchanger, a pump, a valve, a pipe, and a control board. There are a plurality of types of heat insulating materials 2 having different shapes, and different types of heat insulating materials 2 are used depending on the model of the hot water storage type water heater. For example, a heat insulating material 2 having a different position of the protruding portion 2a in the vertical direction or the horizontal direction is used depending on the model of the hot water storage type water heater.

図４は、断熱材２の一部を示す断面図である。図４に示すように、断熱材２は、成形断熱材５と、成形断熱材５の表面の少なくとも一部を覆うフィルム４との一体成形品である。例えば発泡ポリウレタンあるいは発泡ポリスチレンのような発泡プラスチックを金型で成形することにより成形断熱材５が形成される。その成形時に、金型内にフィルム４が配置される。フィルム４は、金型の内壁に接する。成形断熱材５が形成されると、フィルム４が成形断熱材５と一体化する。成形断熱材５と金型の内壁との間にフィルム４があることで、成形断熱材５が金型に接着することを防止できるので、容易に離型することができる。 FIG. 4 is a cross-sectional view showing a part of the heat insulating material 2. As shown in FIG. 4, the heat insulating material 2 is an integrally molded product of the molded heat insulating material 5 and the film 4 that covers at least a part of the surface of the molded heat insulating material 5. For example, the molded heat insulating material 5 is formed by molding a foamed plastic such as polyurethane foam or polystyrene foam with a mold. At the time of molding, the film 4 is arranged in the mold. The film 4 is in contact with the inner wall of the mold. When the molded heat insulating material 5 is formed, the film 4 is integrated with the molded heat insulating material 5. Since the film 4 is provided between the molded heat insulating material 5 and the inner wall of the mold, it is possible to prevent the molded heat insulating material 5 from adhering to the mold, so that the mold can be easily released.

図示を省略するが、断熱材３は、断熱材２と同様に、成形断熱材５とその表面の少なくとも一部を覆うフィルム４との一体成形品である。 Although not shown, the heat insulating material 3 is an integrally molded product of the molded heat insulating material 5 and the film 4 covering at least a part of the surface thereof, similarly to the heat insulating material 2.

断熱材２及び断熱材３は、同一の機種の貯湯式給湯機に用いられる。すなわち、断熱材２及び断熱材３は、一つの貯湯タンク１に対して組み付けられる。断熱材３は、断熱材２とは形状が異なる。例えば、断熱材３は、突出部２ａのような部分を有していない。 The heat insulating material 2 and the heat insulating material 3 are used in a hot water storage type water heater of the same model. That is, the heat insulating material 2 and the heat insulating material 3 are assembled to one hot water storage tank 1. The heat insulating material 3 has a different shape from the heat insulating material 2. For example, the heat insulating material 3 does not have a portion such as a protruding portion 2a.

本開示の貯湯式給湯機用断熱材は、第一断熱材と、第一断熱材とは形状が異なる第二断熱材とを含む。断熱材２が第一断熱材に対応し、断熱材３が第二断熱材に対応してもよい。その場合、第一断熱材及び第二断熱材は、同一の機種の貯湯式給湯機に用いられる。あるいは、複数種類の断熱材２のうちの一つが第一断熱材に対応し、第一断熱材とは形状が異なる別の種類の断熱材２が第二断熱材に対応してもよい。その場合、第一断熱材及び第二断熱材は、互いに異なる機種の貯湯式給湯機に用いられる。 The heat insulating material for a hot water storage type water heater of the present disclosure includes a first heat insulating material and a second heat insulating material having a shape different from that of the first heat insulating material. The heat insulating material 2 may correspond to the first heat insulating material, and the heat insulating material 3 may correspond to the second heat insulating material. In that case, the first heat insulating material and the second heat insulating material are used for the same type of hot water storage type water heater. Alternatively, one of the plurality of types of heat insulating material 2 may correspond to the first heat insulating material, and another type of heat insulating material 2 having a shape different from that of the first heat insulating material may correspond to the second heat insulating material. In that case, the first heat insulating material and the second heat insulating material are used for hot water storage type water heaters of different models.

フィルム４の少なくとも一部は、有色である。以下の説明では、フィルム４の少なくとも一部が有する色を単に「フィルム４の色」と称する。フィルム４の全体が有色でもよい。あるいは、フィルム４は、着色された有色部分と、着色されていない無色部分とを有してもよい。有色部分は、不透明でもよいし、有色透明でもよい。無色部分の色は、フィルム４の素材自体の色、すなわち地色である。無色部分は、不透明でもよいし、無色透明でもよい。フィルム４の少なくとも一部に着色を施した後に、そのフィルム４を金型内に配置して成形断熱材５を成形してもよい。あるいは、金型での成形によって成形断熱材５がフィルム４と一体化した後にフィルム４の少なくとも一部に着色を施してもよい。 At least a portion of film 4 is colored. In the following description, the color possessed by at least a part of the film 4 is simply referred to as "the color of the film 4". The entire film 4 may be colored. Alternatively, the film 4 may have a colored portion and an uncolored colorless portion. The colored portion may be opaque or colored transparent. The color of the colorless portion is the color of the material itself of the film 4, that is, the ground color. The colorless portion may be opaque or colorless and transparent. After coloring at least a part of the film 4, the film 4 may be arranged in a mold to mold the molding heat insulating material 5. Alternatively, at least a part of the film 4 may be colored after the molded heat insulating material 5 is integrated with the film 4 by molding with a mold.

第二断熱材のフィルム４の色は、第一断熱材のフィルム４の色とは異なる。これにより、以下のような効果が得られる。フィルム４の色の違いにより、第一断熱材と第二断熱材とを取り違えることなく容易に識別できる。第一断熱材と第二断熱材とが一緒に生産される場合に、第一断熱材と第二断熱材とを間違えずに容易に仕分けすることができる。第一断熱材と第二断熱材とを取り違えることなく貯湯タンク１に組み付ける上で有利になるので、誤組み立ての発生を確実に防止することに寄与する。なお、本開示の貯湯式給湯機用断熱材は、第一断熱材及び第二断熱材に加えて、そのいずれに対しても形状が異なる他の断熱材をさらに含んでいてもよい。そして、当該他の断熱材が成形断熱材５とその表面の少なくとも一部を覆うフィルム４との一体成形品である場合に、当該他の断熱材のフィルム４の色が、第一断熱材及び第二断熱材のいずれのフィルム４に対しても異なる色となるように構成してもよい。 The color of the film 4 of the second heat insulating material is different from the color of the film 4 of the first heat insulating material. As a result, the following effects can be obtained. Due to the difference in color of the film 4, the first heat insulating material and the second heat insulating material can be easily distinguished without being mistaken for each other. When the first heat insulating material and the second heat insulating material are produced together, the first heat insulating material and the second heat insulating material can be easily sorted without being mistaken. Since it is advantageous for assembling the first heat insulating material and the second heat insulating material to the hot water storage tank 1 without confusing them, it contributes to surely prevent the occurrence of erroneous assembly. The heat insulating material for a hot water storage type water heater of the present disclosure may further contain other heat insulating materials having different shapes from each of the first heat insulating material and the second heat insulating material. When the other heat insulating material is an integrally molded product of the molded heat insulating material 5 and the film 4 covering at least a part of the surface thereof, the color of the film 4 of the other heat insulating material is the first heat insulating material and It may be configured to have a different color for any of the films 4 of the second heat insulating material.

本実施の形態において、第一断熱材の一部の形状が第二断熱材とは異なり、当該一部以外の第一断熱材の形状が第二断熱材と共通する。例えば、断熱材２が第一断熱材に対応し、断熱材３が第二断熱材に対応する場合、突出部２ａを含む一部において断熱材２の形状が断熱材３とは異なり、それ以外の部分においては断熱材２及び断熱材３は半円筒状の共通の形状を有する。また、突出部２ａの位置あるいは形状が異なる二つの断熱材２のうち、一方が第一断熱材に対応し、他方が第二断熱材に対応する場合、突出部２ａを含む一部において両者の形状が異なり、それ以外の部分において両者の形状が共通する。このように、本実施の形態において、第一断熱材と第二断熱材とは互いに類似した形状を有する。特に、突出部２ａの位置あるいは形状が異なる断熱材２のように、第一断熱材と第二断熱材とが機種違いの貯湯式給湯機に用いられるものである場合には、両者の形状が極めて類似している場合がある。仮にフィルム４の色の違いがないと、類似した形状の第一断熱材と第二断熱材とを取り違えやすい。これに対し、本実施の形態であれば、フィルム４の色の違いにより、類似した形状の第一断熱材と第二断熱材とを取り違えることなく容易に識別できる。 In the present embodiment, the shape of a part of the first heat insulating material is different from that of the second heat insulating material, and the shape of the first heat insulating material other than the part is common to the second heat insulating material. For example, when the heat insulating material 2 corresponds to the first heat insulating material and the heat insulating material 3 corresponds to the second heat insulating material, the shape of the heat insulating material 2 is different from that of the heat insulating material 3 in a part including the protrusion 2a, and other than that. In this part, the heat insulating material 2 and the heat insulating material 3 have a common semi-cylindrical shape. Further, when one of the two heat insulating materials 2 having different positions or shapes of the protruding portions 2a corresponds to the first heat insulating material and the other corresponds to the second heat insulating material, both of them are partly including the protruding portion 2a. The shapes are different, and both shapes are common in other parts. As described above, in the present embodiment, the first heat insulating material and the second heat insulating material have shapes similar to each other. In particular, when the first heat insulating material and the second heat insulating material are used for hot water storage type water heaters of different models, such as the heat insulating material 2 having different positions or shapes of the protrusions 2a, the shapes of both are different. It may be very similar. If there is no difference in the colors of the film 4, it is easy to mistake the first heat insulating material and the second heat insulating material having similar shapes. On the other hand, in the present embodiment, the first heat insulating material and the second heat insulating material having similar shapes can be easily distinguished from each other due to the difference in color of the film 4.

フィルム４に印刷部を設けてもよい。印刷部を形成する方法は、特に限定されないが、例えばレーザー印刷でもよい。第一断熱材のフィルム４の印刷部と、第二断熱材のフィルム４の印刷部とが、互いに異なる内容を有していてもよい。そのようにすることで、第一断熱材と第二断熱材とをさらに容易に識別できる。 A printing portion may be provided on the film 4. The method for forming the printed portion is not particularly limited, and for example, laser printing may be used. The printed portion of the film 4 of the first heat insulating material and the printed portion of the film 4 of the second heat insulating material may have different contents from each other. By doing so, the first heat insulating material and the second heat insulating material can be more easily distinguished.

フィルム４の印刷部の内容は、その断熱材が適用される貯湯式給湯機の機種に関する情報を含んでいてもよい。例えば、貯湯式給湯機の機種を示す名称、番号、記号などが印刷部に含まれていてもよい。これにより、その断熱材が適用される貯湯式給湯機の機種を容易に確認できる。 The content of the printing section of the film 4 may include information about the model of the hot water storage type water heater to which the heat insulating material is applied. For example, the printing unit may include a name, number, symbol, or the like indicating the model of the hot water storage type water heater. This makes it possible to easily confirm the model of the hot water storage type water heater to which the heat insulating material is applied.

フィルム４の印刷部の内容は、第一断熱材または第二断熱材の取付位置及び取付方向の少なくとも一方に関する情報を含んでいてもよい。例えば、その断熱材が、貯湯タンク１の正面側に配置されるか背面側に設置されるかなどの情報、あるいは断熱材の上下方向を示す情報などが印刷部に含まれていてもよい。これにより、その断熱材が貯湯タンク１に組み付けるときに適正な個所に容易に組み付けることができる。 The content of the printed portion of the film 4 may include information regarding at least one of the mounting position and mounting direction of the first heat insulating material or the second heat insulating material. For example, the printing unit may include information such as whether the heat insulating material is arranged on the front side or the back side of the hot water storage tank 1, or information indicating the vertical direction of the heat insulating material. As a result, when the heat insulating material is assembled to the hot water storage tank 1, it can be easily assembled at an appropriate place.

フィルム４の少なくとも一部が透明である場合には、フィルム４の上から成形断熱材５の表面の状態を確認できる。このため、例えばボイドのように断熱性能に影響を及ぼし得る気泡跡が成形断熱材５に発生していないかどうかを確認できるという利点がある。フィルム４の一部の領域を有色透明とし、残りの領域を無色透明とすることで、フィルム４の全体を透明としてもよい。これにより、成形断熱材５の表面の状態を確認する上でさらに有利になる。 When at least a part of the film 4 is transparent, the state of the surface of the molded heat insulating material 5 can be confirmed from above the film 4. Therefore, there is an advantage that it is possible to confirm whether or not bubble traces that may affect the heat insulating performance such as voids are generated in the molded heat insulating material 5. By making a part of the film 4 colored and transparent and the remaining area colorless and transparent, the entire film 4 may be made transparent. This is further advantageous in confirming the state of the surface of the molded heat insulating material 5.

フィルム４が有色部分と無色部分とを有する場合には、着色を施す有色部分の面積が小さくて済むので、製造コストの低減に有利になる。また、有色部分の面積が小さくなることで、製品組立後に、断熱材２と断熱材３の色の違いによる美観上の違和感を抑制する上で有利になる。また、貯湯式給湯機に内蔵される部品を組み付ける際の目安となる位置を示すようにフィルム４における有色部分を配置してもよい。これにより、部品を組み付けるときにフィルム４の有色部分を目安にして取付位置を決めることができるので、組み立て作業が容易になる。部品は、例えば、熱交換器、ポンプ、バルブ、配管、制御基板のうちの少なくとも一つでもよい。複数種類の部品に対応した複数の有色部分をフィルム４に配置してもよい。その場合、それぞれの有色部分の色あるいは大きさが相互に異なるようにしてもよい。そのようにすることで、複数種類の部品の取り付け作業がさらに容易になる。 When the film 4 has a colored portion and a colorless portion, the area of the colored portion to be colored can be small, which is advantageous in reducing the manufacturing cost. Further, since the area of the colored portion is reduced, it is advantageous in suppressing an aesthetic discomfort due to the difference in color between the heat insulating material 2 and the heat insulating material 3 after the product is assembled. Further, the colored portion of the film 4 may be arranged so as to indicate a position as a guide when assembling the parts built in the hot water storage type water heater. As a result, when assembling the parts, the mounting position can be determined with reference to the colored portion of the film 4, so that the assembling work becomes easy. The component may be, for example, at least one of a heat exchanger, a pump, a valve, a pipe, and a control board. A plurality of colored portions corresponding to a plurality of types of parts may be arranged on the film 4. In that case, the colors or sizes of the colored portions may be different from each other. By doing so, the work of attaching a plurality of types of parts becomes easier.

以下の説明では、成形断熱材５の表面のうち、貯湯タンク１に向かい合う面を「裏側面」と称し、裏側面とは反対側の面を「表側面」と称する。フィルム４は、貯湯式給湯機用断熱材が貯湯タンク１に組み付けられたときに視認可能となる視認可能部分と、貯湯式給湯機用断熱材が貯湯タンク１に組み付けられたときに視認不能となる視認不能部分とを有していてもよい。例えば、フィルム４のうち、成形断熱材５の表側面を覆う部分が視認可能部分に相当し、成形断熱材５の裏側面を覆う部分が視認不能部分に相当する。 In the following description, of the surfaces of the molded heat insulating material 5, the surface facing the hot water storage tank 1 is referred to as a "back side surface", and the surface opposite to the back side surface is referred to as a "front side surface". The film 4 has a visible portion that becomes visible when the heat insulating material for the hot water storage type water heater is assembled to the hot water storage tank 1, and an invisible part that becomes visible when the heat insulating material for the hot water storage type water heater is assembled to the hot water storage tank 1. It may have an invisible portion. For example, in the film 4, the portion covering the front side surface of the molded heat insulating material 5 corresponds to a visible portion, and the portion covering the back side surface of the molded heat insulating material 5 corresponds to an invisible portion.

フィルム４が視認可能部分と視認不能部分とを有する場合には、視認可能部分の色が視認不能部分の色とは異なるようにすることが好ましい。そのようにすることで、第一断熱材あるいは第二断熱材の表側面と裏側面とを容易に識別できるので、組立作業での取付ミスをより確実に防止でき、作業性が向上する。 When the film 4 has a visible portion and an invisible portion, it is preferable that the color of the visible portion is different from the color of the invisible portion. By doing so, the front side surface and the back side surface of the first heat insulating material or the second heat insulating material can be easily distinguished, so that mounting mistakes in the assembly work can be more reliably prevented and workability is improved.

第一断熱材の視認可能部分の色が第二断熱材の視認可能部分の色とは異なり、第一断熱材の視認不能部分の色が第二断熱材の視認不能部分の色と同色であるようにしてもよい。そのようにすることで、第一断熱材及び第二断熱材が貯湯タンク１に組み付けられた後でも、第一断熱材と第二断熱材とをフィルム４の色の違いによって識別できるので、誤った組み付けがないかどうかを容易に確認できる。 The color of the visible part of the first heat insulating material is different from the color of the visible part of the second heat insulating material, and the color of the invisible part of the first heat insulating material is the same as the color of the invisible part of the second heat insulating material. You may do so. By doing so, even after the first heat insulating material and the second heat insulating material are assembled to the hot water storage tank 1, the first heat insulating material and the second heat insulating material can be identified by the difference in the color of the film 4, which is erroneous. You can easily check if there is any assembly.

上記とは逆に、第一断熱材の視認不能部分の色が第二断熱材の視認不能部分の色とは異なり、第一断熱材の視認可能部分の色が第二断熱材の視認可能部分の色と同色であるようにしてもよい。そのようにすることで、第一断熱材及び第二断熱材が貯湯タンク１に組み付けられた状態での外観においては、第一断熱材と第二断熱材とが同色となるので、色の違いによる違和感を抑制でき、製品の美観が良好になる。 Contrary to the above, the color of the invisible part of the first heat insulating material is different from the color of the invisible part of the second heat insulating material, and the color of the visible part of the first heat insulating material is the visible part of the second heat insulating material. It may be the same color as the color of. By doing so, in the appearance when the first heat insulating material and the second heat insulating material are assembled to the hot water storage tank 1, the first heat insulating material and the second heat insulating material have the same color, so that the colors are different. The discomfort caused by this can be suppressed, and the aesthetic appearance of the product is improved.

また、第一断熱材の視認不能部分の色が第二断熱材の視認不能部分の色とは異なり、第一断熱材の視認可能部分及び第二断熱材の視認可能部分が無色透明であるようにしてもよい。その場合、第一断熱材及び第二断熱材が貯湯タンク１に組み付けられた状態での外観においては、無色透明の視認可能部分を通して成形断熱材５の地色が見えるので、色の違いによる違和感を抑制でき、製品の美観が良好になる。 Further, the color of the invisible part of the first heat insulating material is different from the color of the invisible part of the second heat insulating material, so that the visible part of the first heat insulating material and the visible part of the second heat insulating material are colorless and transparent. You may do it. In that case, in the appearance when the first heat insulating material and the second heat insulating material are assembled to the hot water storage tank 1, the ground color of the molded heat insulating material 5 can be seen through the colorless and transparent visible portion, so that a sense of discomfort due to the difference in color is seen. Can be suppressed and the aesthetic appearance of the product is improved.
