Description

本発明は、所定温度の液体を通水する配管に介設し、液体を一時的に貯留して保温する断熱タンク、特に、この断熱タンクに使用する断熱部材に関するものである。   The present invention relates to a heat insulating tank that is interposed in a pipe for passing a liquid at a predetermined temperature and temporarily stores the liquid to keep it warm, and more particularly to a heat insulating member used for this heat insulating tank.

寒冷地で使用する自動車は、冬場に周囲は勿論、自動車自体も冷えきり、エンジンの始動が困難になる。また、家庭では、温水を吐出可能な給湯機が普及されているが、非使用時間が長くなると、給湯機から水栓までの配管中の水が冷め、給湯を再開した際に温水が吐出されるまでに時間がかかる。   Automobiles that are used in cold regions are cold not only in the winter but also in the surroundings, making it difficult to start the engine. In addition, hot water heaters that can discharge hot water are widely used at home, but if the non-use time becomes longer, the water in the pipe from the water heater to the faucet cools and hot water is discharged when hot water is resumed. It takes time to

そこで、このような液体を通水する配管中に断熱タンクを介設し、この断熱タンク中に液体を一時的に貯留するとともに保温し、通水が再開された時に断熱タンク中の保温した液体を供給可能とする構成が提案されている（特許文献１参照）。   Therefore, an insulating tank is installed in the pipe for passing such liquid, and the liquid is temporarily stored in the insulating tank and kept warm, and when the water flow is resumed, the warmed liquid in the insulating tank is stored. Has been proposed (see Patent Document 1).

この特許文献１の断熱タンクは、筒状をなす胴部の両端に、該胴部より断面積が小さい筒状の首部を設けたタンク本体を備えている。このタンク本体の外周部には、内筒材および外筒材からなる真空二重構造の筒状断熱部材が配設されている。また、筒状断熱部材の上側に位置する開口端には、放熱を防ぐための端部断熱部材が配設されている。この特許文献１では、端部断熱部材を発泡樹脂により構成している。しかし、この断熱タンクは、端部断熱部材が保温性能に大きな影響を及ぼす。   The heat insulation tank of this patent document 1 is provided with the tank main body which provided the cylindrical neck part with a smaller cross-sectional area than this trunk | drum at the both ends of the cylindrical trunk | drum. A tubular heat insulating member having a vacuum double structure made of an inner cylinder material and an outer cylinder material is disposed on the outer periphery of the tank body. Moreover, the edge part heat insulation member for preventing heat dissipation is arrange | positioned at the opening end located above a cylindrical heat insulation member. In Patent Document 1, the end heat insulating member is made of foamed resin. However, in this heat insulating tank, the end heat insulating member greatly affects the heat retaining performance.

この端部断熱部材として好適に使用可能な断熱部材としては、例えば気密性を有する第１および第２シート材でコア材の表面を被覆し、これらシート材の縁を固着することにより、内部のコア材を密閉したものが挙げられる（特許文献２参照）。この特許文献２には、所定位置に貫通孔や切欠部を設ける構成も記載されている。これらは、コア材に貫通孔や切欠部を設けておき、シート材を被覆して周囲を固着（熱溶着）した後、貫通孔または切欠部の縁から所定間隔をもった位置を打ち抜く構成としている。   As a heat insulating member that can be suitably used as the end heat insulating member, for example, the surface of the core material is covered with the first and second sheet materials having airtightness, and the edges of these sheet materials are fixed, so What sealed the core material is mentioned (refer patent document 2). This Patent Document 2 also describes a configuration in which a through hole or a notch is provided at a predetermined position. These have a structure in which a through hole or notch is provided in the core material, the sheet material is covered and the periphery is fixed (thermal welding), and then a position having a predetermined interval is punched from the edge of the through hole or notch. Yes.

しかし、この断熱部材は、内部の真空状態を維持するために、シート材の固着部を大きな固着面積で形成する必要がある。その結果、特許文献１に記載の筒状断熱部材の開口部に嵌め込んで使用する場合には種々の問題が生じる。即ち、コア材を筒状断熱部材の内法と一致する形状とした場合には、組付状態で固着部が変形するため、組付作業性が悪くなるばかりか、最悪の場合にはリークが生じる。一方、コア材を筒状断熱部材の内法より小さく形成した場合には、開口部にコア材を配置していない領域が発生するため、断熱性能が低下する。   However, in this heat insulating member, in order to maintain an internal vacuum state, it is necessary to form the fixing portion of the sheet material with a large fixing area. As a result, various problems arise when used by being fitted into the opening of the cylindrical heat insulating member described in Patent Document 1. That is, when the core material has a shape that matches the inner method of the cylindrical heat insulating member, the fixing portion is deformed in the assembled state, so that not only the assembling workability is deteriorated, but also leakage is caused in the worst case. Arise. On the other hand, when the core material is formed smaller than the inner method of the cylindrical heat insulating member, a region in which the core material is not disposed in the opening portion occurs, so that the heat insulating performance is deteriorated.

これに対して、シート材の固着部を、コア材に対して直交方向に突出するように設けた断熱部材が提供されている（特許文献３参照）。このようにすれば、端部断熱部材のコア材と筒状断熱部材との間に隙間が発生しない構成とすることができるため、断熱性能を向上できる。   On the other hand, the heat insulation member which provided the adhering part of the sheet | seat material so that it might protrude in the orthogonal direction with respect to a core material is provided (refer patent document 3). If it does in this way, since it can be set as the structure which a clearance gap does not generate | occur | produce between the core material of an edge part heat insulation member, and a cylindrical heat insulation member, heat insulation performance can be improved.

しかしながら、この断熱部材を適用する特許文献１のタンク本体は、液体を流入および流出させる首部の開口を貫通させて露出させる必要があるため、特許文献３の断熱部材は適用できない。仮に、特許文献３の構成に、特許文献２に記載の貫通孔を設ける構成を適用した場合には、この部分にコア材を設けていない領域が生じるため、断熱性能の低下は否めない。   However, since the tank body of Patent Document 1 to which this heat insulating member is applied needs to be exposed through the opening of the neck part through which the liquid flows in and out, the heat insulating member of Patent Document 3 cannot be applied. Temporarily, when the structure which provides the through-hole of patent document 2 is applied to the structure of patent document 3, since the area | region which does not provide the core material arises in this part, decline in heat insulation performance cannot be denied.

本発明は、従来の問題に鑑みてなされたもので、断熱性能を低下させることなく、内部に所定の対象物を貫通可能な断熱部材を提供することを課題とするものである。そして、この断熱部材を適用した保温性能が高い断熱タンクを提供するものである。   This invention is made | formed in view of the conventional problem, and makes it a subject to provide the heat insulation member which can penetrate a predetermined target object inside, without reducing heat insulation performance. And the heat insulation tank with which heat insulation performance to which this heat insulation member is applied is provided.

前記課題を解決するため、本発明の断熱部材は、コア材の表面を気密性を有する第１および第２シート材で被覆し、これらシート材の縁を固着することにより内部のコア材を密閉した断熱部材において、前記コア材に、第１面から対向する第２面にかけて貫通する貫通孔を設け、前記第１シート材に、前記貫通孔を構成する内周面に沿って延びる内周面被覆部を設け、かつ、第１シート材に、前記貫通孔の軸方向に沿って延びるように前記内周面被覆部と連続する固着部を設けるとともに、前記第２シート材に、前記固着部に重畳して密閉状態に固着される被固着部を設けた構成としている。   In order to solve the above-described problems, the heat insulating member of the present invention covers the surface of the core material with the first and second sheet materials having airtightness, and seals the inner core material by fixing the edges of these sheet materials. In the heat insulating member, the core material is provided with a through hole penetrating from the first surface to the second surface facing the inner surface, and the first sheet material has an inner peripheral surface extending along an inner peripheral surface constituting the through hole. A covering portion is provided, and a fixing portion that is continuous with the inner peripheral surface covering portion is provided on the first sheet material so as to extend along the axial direction of the through hole, and the fixing portion is provided on the second sheet material. It is set as the structure which provided the to-be-adhered part which overlaps and adheres to a sealing state.

また、この断熱部材を適用する断熱タンクは、胴部、および、該胴部の少なくとも一端に該胴部より断面積が小さい首部を有し、該首部の先端を開口したタンク本体と、前記タンク本体の外周部を囲繞する内筒材および外筒材からなる真空二重構造の筒状断熱部材と、前記タンク本体の首部が位置する筒状断熱部材の開口部を閉塞する端部断熱部材とを備え、この端部断熱部材を、前記構成としたものである。   Further, a heat insulating tank to which the heat insulating member is applied includes a body, a tank body having a neck having a smaller cross-sectional area than the body at one end of the body, and an opening at the tip of the neck, and the tank A tubular heat insulating member having a vacuum double structure composed of an inner tube member and an outer tube member surrounding the outer peripheral portion of the main body, and an end heat insulating member closing the opening of the tubular heat insulating member where the neck of the tank main body is located; The end heat insulating member is configured as described above.

本発明の断熱部材は、コア材に貫通孔を設け、この貫通孔の内周部を密閉するために、シート材に貫通孔の軸方向に沿って延びる固着部を設けているため、貫通孔の内周部には内向きに突出する部分が形成されない。そして、この断熱部材を断熱タンクに適用した場合、貫通孔の内部にタンク本体の首部を挿通させることにより、首部の外周部までコア材を配設できる。その結果、首部の外周部からの放熱を抑制できるため、断熱性能を大幅に向上できる。また、固着部は、首部の外周部に沿って延びるように組み付けられるため、製造誤差により首部の外周部に多少の隙間が発生しても、その隙間からの放熱を抑制できる。   Since the heat insulating member of the present invention has a through hole in the core material, and the sheet material has a fixing portion extending along the axial direction of the through hole in order to seal the inner peripheral portion of the through hole, the through hole A portion projecting inwardly is not formed on the inner peripheral portion. And when this heat insulation member is applied to a heat insulation tank, a core material can be arrange | positioned to the outer peripheral part of a neck part by inserting the neck part of a tank main body into the inside of a through-hole. As a result, since heat dissipation from the outer periphery of the neck can be suppressed, the heat insulation performance can be greatly improved. Further, since the fixing portion is assembled so as to extend along the outer peripheral portion of the neck portion, even if a slight gap occurs in the outer peripheral portion of the neck portion due to a manufacturing error, heat radiation from the gap can be suppressed.

この断熱タンクは、前記タンク本体の首部の開口に所定温度の液体を通水する上流側配管および下流側配管が接続され、上流側配管から下流側配管へ通水する液体を一時的に貯留し、前記断熱部材により保温するものである。   In this heat insulation tank, an upstream pipe and a downstream pipe for passing a liquid at a predetermined temperature are connected to the opening of the neck portion of the tank body, and temporarily store the liquid flowing from the upstream pipe to the downstream pipe. The temperature is kept by the heat insulating member.

また、この断熱タンクには、前記タンク本体は、一端に前記首部を設け、他端に閉塞部を設けた構成とし、この閉塞部に軸方向外向きに突出する凸部を設け、前記タンク本体の閉塞部が位置する筒状断熱部材の開口部に、前記タンク本体の凸部を嵌合して位置決めする位置決め部を設けたコア材と、該コア材の表面を被覆する気密性を有する第１および第２シート材とを備え、これらシート材をコア材の外周部の一端縁で固着した第２端部断熱部材を配設することが好ましい。このようにすれば、振動などの外力が加わってもタンク本体が筒状断熱部材に干渉することはない。よって、耐振性を向上できるとともに、製品の安定性を向上できる。   Further, in this heat insulating tank, the tank main body has a configuration in which the neck portion is provided at one end and a closing portion is provided at the other end, and a protruding portion protruding outward in the axial direction is provided at the closing portion. A core material provided with a positioning part for fitting and positioning the convex part of the tank main body at the opening of the cylindrical heat insulating member where the closed part of the gas is closed, and an airtight property covering the surface of the core material It is preferable to dispose a second end heat insulating member that includes the first sheet material and the second sheet material and to which the sheet material is fixed at one end edge of the outer peripheral portion of the core material. In this way, the tank body does not interfere with the cylindrical heat insulating member even when an external force such as vibration is applied. Therefore, the vibration resistance can be improved and the stability of the product can be improved.

さらに、前記筒状断熱部材の開口部に、前記端部断熱部材の外面を位置決めする位置決め片を設けることが好ましい。このようにすれば、端部断熱部材の組付状態を確実に維持できる。よって、製品の安定性を更に向上できる。   Furthermore, it is preferable to provide a positioning piece for positioning the outer surface of the end heat insulating member at the opening of the cylindrical heat insulating member. In this way, the assembled state of the end heat insulating member can be reliably maintained. Therefore, the stability of the product can be further improved.

本発明の断熱部材では、シート材にコア材の貫通孔の軸方向に沿って延びる固着部を設けているため、貫通孔の内周部には内向きに突出する部分を設けない構成とすることができる。よって、この断熱部材を断熱タンクに適用した場合、タンク本体の首部の外周部までコア材を配設できる。その結果、断熱性能を大幅に向上できる。   In the heat insulating member of the present invention, since the fixing portion extending along the axial direction of the through hole of the core material is provided in the sheet material, the inner peripheral portion of the through hole is not provided with a portion protruding inward. be able to. Therefore, when this heat insulating member is applied to a heat insulating tank, the core material can be disposed up to the outer periphery of the neck of the tank body. As a result, the heat insulation performance can be greatly improved.

As a result, the liquid that has flowed into the tank body 11 from the upstream connection pipe 16 is supplied from the downstream connection pipe 17 to the downstream side through the tank body 11. Further, when the liquid supply from the upstream pipe is cut off, the liquid supplied in the tank body 11 is stored in the tank body 11. Further, when the liquid supply is resumed, the liquid stored in the tank body 11 is supplied to the downstream pipe.
