Description

本発明は、自動販売機、冷凍・冷蔵ショーケース、冷蔵庫、冷凍庫、その他の種々の製品に使用される断熱材に関する。   The present invention relates to a heat insulating material used for a vending machine, a freezer / refrigerated showcase, a refrigerator, a freezer, and other various products.

従来、この種の断熱材として、断熱箱体を構成する外箱と内箱との間に形成された空間部に注入することによって、断熱箱体の断熱性を向上させる断熱材が知られている（例えば、特許文献１参照）。この断熱材は、液状の状態で空間部に注入された後、空間部内において発泡して充填される。   Conventionally, as this type of heat insulating material, a heat insulating material that improves the heat insulating property of the heat insulating box by injecting it into the space formed between the outer box and the inner box constituting the heat insulating box is known. (For example, refer to Patent Document 1). The heat insulating material is injected into the space in a liquid state, and then foamed and filled in the space.

しかしながら、従来の断熱材では、空間部の隅にまで確実に注入することができないため、断熱箱体の断熱性が低下するおそれがあった。また、断熱箱体を解体する際に発泡した断熱材から塵埃が生じるおそれがある上に、解体した後の断熱材を再利用することができないという問題があった。   However, in the conventional heat insulating material, since it cannot inject | pour reliably to the corner of a space part, there existed a possibility that the heat insulation of a heat insulation box might fall. In addition, there is a problem that dust may be generated from the foamed heat insulating material when the heat insulating box is disassembled, and the heat insulating material after dismantling cannot be reused.

そこで、上記問題を解決するために組み立て式の断熱材が開示されている（例えば、特許文献２参照）。この断熱材は、真空断熱材と、この真空断熱材の周囲に配置される複数のウレタン材と、金属製の背面板と、金属製の内壁とから構成され、真空断熱材及びウレタン材の前面及び背面全体を金属製の内壁と背面板とによって狭持されるようになっている。このように構成された断熱材は、断熱箱体の背面板と内壁との間の隅まで真空断熱材とウレタン材とを確実に配置させることができるので、断熱性の低下を防止できる。また、この断熱材は、塵埃を生じさせることなく解体することができる上に、分解後の断熱材を再利用することができる。
特開平８−６１８３７号公報 特開２００１−１８５５４号公報 Then, in order to solve the said problem, the assembly-type heat insulating material is disclosed (for example, refer patent document 2). The heat insulating material is composed of a vacuum heat insulating material, a plurality of urethane materials arranged around the vacuum heat insulating material, a metal back plate, and a metal inner wall, and the front surfaces of the vacuum heat insulating material and the urethane material. In addition, the entire back surface is held between a metal inner wall and a back plate. The heat insulating material configured as described above can reliably dispose the vacuum heat insulating material and the urethane material up to the corner between the back plate and the inner wall of the heat insulating box, so that a decrease in heat insulating property can be prevented. In addition, the heat insulating material can be disassembled without generating dust, and the heat insulating material after decomposition can be reused.

しかしながら、前述のように構成された断熱材は、真空断熱材及びウレタン材の前面及び背面全体を金属製の内壁と背面板とによって狭持するので、断熱材全体が重くなることから、取り扱いが困難となり、作業性が低下するおそれがあった。   However, since the heat insulating material configured as described above sandwiches the entire front and back surfaces of the vacuum heat insulating material and the urethane material with the metal inner wall and the back plate, the entire heat insulating material becomes heavy, so that it can be handled. It becomes difficult and workability may be reduced.

また、前述の断熱材は、複数の金属板を構成部品としているので、製造コストが高くなるという問題点を有していた。   Moreover, since the above-mentioned heat insulating material uses a plurality of metal plates as components, there is a problem that the manufacturing cost is increased.

さらに、真空断熱材及びウレタン材の前面及び背面全体を金属製の内壁と背面板とによって狭持しているので、厚さ寸法が大きくなるという問題があった。このため、例えば前述の断熱材を自動販売機の断熱壁として使用した場合には、自動販売機本体が大型化することになる。   Furthermore, since the entire front and back surfaces of the vacuum heat insulating material and the urethane material are held between the metal inner wall and the back plate, there is a problem that the thickness dimension becomes large. For this reason, for example, when the above-mentioned heat insulating material is used as a heat insulating wall of a vending machine, the vending machine main body is enlarged.

本発明は、上記事情に鑑みてなされたものであり、その目的とするところは、取り扱い易くすることで作業性を高めることができ、しかも製造コストを抑えることができ、更には厚さ寸法を小さくすることのできる断熱材を提供することにある。   The present invention has been made in view of the above circumstances, and the object of the present invention is to improve the workability by making it easy to handle, and to reduce the manufacturing cost, and further to reduce the thickness dimension. It is in providing the heat insulating material which can be made small.

上記目的を達成するために、本発明の断熱材は、厚さ方向に所定の大きさの凹部を設けた第１の断熱部材と、前記第１の断熱部材の凹部に収納され、第１の断熱部材よりも断熱性の高い第２の断熱部材と、前記第２の断熱部材を被覆する被覆材とを備えた構成となっている。   In order to achieve the above object, a heat insulating material of the present invention is housed in a first heat insulating member having a concave portion of a predetermined size in the thickness direction, and a concave portion of the first heat insulating member, It has the structure provided with the 2nd heat insulation member with higher heat insulation than a heat insulation member, and the coating | covering material which coat | covers the said 2nd heat insulation member.

この断熱材によれば、第１の断熱部材の厚さ方向に設けられた凹部に第２の断熱部材を収納し、フィルム形状の被覆材によって第２の断熱部材を被覆して形成するようになっている。これにより、断熱材は、金属製の板等の重量のある部品を多く用いることなく形成されるので、断熱材の厚さ寸法が小さくなるとともに、断熱材の軽量化が図られる。   According to this heat insulating material, the second heat insulating member is housed in the concave portion provided in the thickness direction of the first heat insulating member, and the second heat insulating member is covered with the film-shaped covering material. It has become. Thereby, since a heat insulating material is formed without using many heavy components, such as a metal board, the thickness dimension of a heat insulating material becomes small and the weight reduction of a heat insulating material is achieved.

また、上記目的を達成するために、本発明の断熱材は、厚さ方向に貫通した所定の大きさの貫通部を設けた第１の断熱部材と、前記第１の断熱部材の貫通部に収納され、第１の断熱部材よりも断熱性の高い第２の断熱部材と、前記第２の断熱部材を被覆する被覆材とを備えた構成となっている。   Moreover, in order to achieve the said objective, the heat insulating material of this invention is the 1st heat insulation member which provided the penetration part of the predetermined | prescribed magnitude | size penetrated in the thickness direction, and the penetration part of the said 1st heat insulation member. It is configured to include a second heat insulating member that is housed and has a higher heat insulating property than the first heat insulating member, and a covering material that covers the second heat insulating member.

この断熱材によれば、第１の断熱部材に所定の大きさで厚さ方向に貫通して設けられた貫通部に第２の断熱部材を収納し、この第２の断熱部材をフィルム形状の被覆材によって被覆して形成するようになっている。これにより、断熱材は、金属製の板等の重量のある部品を多く用いることなく形成される。   According to this heat insulating material, the second heat insulating member is housed in the through-hole provided in the first heat insulating member so as to penetrate the first heat insulating member in the thickness direction, and the second heat insulating member is formed into a film shape. It is formed by covering with a covering material. Thereby, a heat insulating material is formed, without using many heavy components, such as a metal board.

本発明によれば、金属製の板等の重量のある部品を多く用いることなく形成されることから、断熱材の軽量化を図ることができるので、断熱材が取り扱い易くなり、例えば自動販売機等の外箱に充填する等において作業性を高めることができる。また、金属製の板等の高価な部品を多く用いないので、製造コストを抑えることができる。さらに、断熱材の厚さ寸法を小さくすることができるので、例えば自動販売機の断熱壁として断熱材を用いる場合に自動販売機本体の小型化を図ることができる。   According to the present invention, the heat insulating material can be reduced in weight because it is formed without using many heavy parts such as a metal plate. The workability can be improved when the outer box is filled. Moreover, since many expensive parts, such as a metal board, are not used, manufacturing cost can be held down. Furthermore, since the thickness dimension of a heat insulating material can be made small, when using a heat insulating material as a heat insulation wall of a vending machine, for example, size reduction of a vending machine main body can be achieved.

図１乃至図４は本発明の一実施形態を示すもので、図１は断熱材の全体分解斜視図、図２は断熱材の概略平面断面図、図３は第２の断熱部材の概略平面断面図、図４は断熱材の概略平面断面図を示す。   1 to 4 show an embodiment of the present invention. FIG. 1 is an overall exploded perspective view of a heat insulating material, FIG. 2 is a schematic plan sectional view of the heat insulating material, and FIG. 3 is a schematic plan view of a second heat insulating member. Sectional drawing and FIG. 4 show schematic plane sectional drawing of a heat insulating material.

断熱材は、第１の断熱部材１０、第２の断熱部材２０及び被覆材３０から構成されている。   The heat insulating material includes the first heat insulating member 10, the second heat insulating member 20, and the covering material 30.

第１の断熱部材１０は、幅Ｘ、高さＹ及び厚さＺの大きさからなる凹部１１を、第１の断熱部材１０の中央領域で、且つ、第１の断熱部材１０の厚さ方向に設けている。この凹部１１の厚さＺは、第１の断熱部材１０の厚さよりも小さくなるように設定されている。また、凹部は、第１の断熱部材１０をプレス加工して圧縮することによって形成されている。さらに、第１の断熱部材１０はウレタン材から形成されている。   The first heat insulating member 10 includes a recess 11 having a width X, a height Y, and a thickness Z in the central region of the first heat insulating member 10 and in the thickness direction of the first heat insulating member 10. Provided. The thickness Z of the recess 11 is set to be smaller than the thickness of the first heat insulating member 10. Moreover, the recessed part is formed by pressing the 1st heat insulation member 10 and compressing. Furthermore, the 1st heat insulation member 10 is formed from the urethane material.

第２の断熱部材２０の大きさは幅Ｘ、高さＹ及び厚さＺであり、第１の断熱部材１０の凹部１１と同じ大きさとなるように形成されている。第１の断熱部材１０の凹部１１に隙間なく収納されるようになっている。この第２の断熱部材２０は、通気性及び断熱性を有する繊維状のグラスウール２１と、このグラスウール２１の全体を被覆する気密性のラミネートフィルム２２とから構成されている。このラミネートフィルム２２の周縁には、ラミネートフィルム２２の内部を吸引するための図示しない吸引口が設けられている。この吸引口からラミネートフィルム２２の内部を吸引することにより、第２の断熱部材２０の内部が真空状態となり、周縁部２３が形成され、第２の断熱部材２０は真空断熱材となる。また、第２の断熱部材２０は真空断熱材なので、第１の断熱部材１０よりも断熱性が高いものである。   The size of the second heat insulating member 20 is a width X, a height Y, and a thickness Z, and is formed to have the same size as the concave portion 11 of the first heat insulating member 10. The first heat insulating member 10 is accommodated in the recess 11 without a gap. The second heat insulating member 20 includes a fibrous glass wool 21 having air permeability and heat insulating properties, and an airtight laminate film 22 that covers the entire glass wool 21. A suction port (not shown) for sucking the inside of the laminate film 22 is provided on the periphery of the laminate film 22. By sucking the inside of the laminate film 22 from this suction port, the inside of the second heat insulating member 20 is in a vacuum state, the peripheral edge 23 is formed, and the second heat insulating member 20 becomes a vacuum heat insulating material. Further, since the second heat insulating member 20 is a vacuum heat insulating material, the heat insulating property is higher than that of the first heat insulating member 10.

被覆材３０は樹脂製のフィルム形状であり、第１の断熱部材１０の凹部１１及び第２の断熱部材２０よりも幅及び高さが大きくなるように形成されている。この被覆材３０は、凹部１１に収納された後の第２の断熱部材２０の外側表面を被覆して貼着するようになっている。   The covering material 30 is in the form of a resin film, and is formed so that the width and height are larger than those of the recess 11 of the first heat insulating member 10 and the second heat insulating member 20. The covering material 30 covers and adheres to the outer surface of the second heat insulating member 20 after being accommodated in the recess 11.

このように構成された断熱材の製造工程及び作用について説明する。   The manufacturing process and operation of the heat insulating material configured as described above will be described.

まず、第２の断熱部材２０を第１の断熱部材１０の凹部１１に隙間なく収納する。このとき、第２の断熱部材２０は、図４に示すように、周縁部２３を折り込んで凹部１１に収納されるようになっている。次に、第１の断熱部材１０の凹部１１に収納された第２の断熱部材２０の外側表面を被覆材３０によって被覆することによって、断熱材が形成される。したがって、この断熱材は、金属製の板等の重量のある部品を用いることなく形成される。   First, the second heat insulating member 20 is stored in the recess 11 of the first heat insulating member 10 without a gap. At this time, as shown in FIG. 4, the second heat insulating member 20 is accommodated in the concave portion 11 by folding the peripheral edge portion 23. Next, the heat insulating material is formed by covering the outer surface of the second heat insulating member 20 accommodated in the recess 11 of the first heat insulating member 10 with the covering material 30. Therefore, this heat insulating material is formed without using heavy components such as a metal plate.

このように本実施形態の断熱材によれば、金属製の板等の重量のある部品を用いることなく形成されることから、断熱材の軽量化を図ることができるので、断熱材が取り扱い易くなり、例えば自動販売機等の外箱に充填する等の場合において作業性を高めることができる。   Thus, according to the heat insulating material of this embodiment, since it is formed without using heavy components such as a metal plate, the heat insulating material can be reduced in weight, so that the heat insulating material is easy to handle. Thus, for example, workability can be improved when filling an outer box of a vending machine or the like.

また、本実施形態の断熱材によれば、金属製の板等の高価な部品が不要なので、製造コストを抑えることができる。   Moreover, according to the heat insulating material of this embodiment, since expensive parts, such as a metal board, are unnecessary, manufacturing cost can be held down.

さらに、本実施形態の断熱材によれば、断熱材の厚さ寸法を小さくすることができるので、例えば自動販売機の断熱壁として断熱材を用いる場合に自動販売機本体の小型化を図ることができる。   Furthermore, according to the heat insulating material of the present embodiment, since the thickness dimension of the heat insulating material can be reduced, for example, when the heat insulating material is used as the heat insulating wall of the vending machine, the vending machine body can be downsized. Can do.

また、本実施形態の断熱材によれば、フィルム形状の被覆材３０によって、第１の断熱部材１０の凹部１１に収納した後の第２の断熱部材２０の外側表面を被覆したので、確実に第２の断熱部材２０を第１の断熱部材１０の凹部１１に収納することができる。   Moreover, according to the heat insulating material of the present embodiment, the outer surface of the second heat insulating member 20 after being housed in the concave portion 11 of the first heat insulating member 10 is covered with the film-shaped covering material 30, so The second heat insulating member 20 can be stored in the recess 11 of the first heat insulating member 10.

さらに、本実施形態の断熱材によれば、第２の断熱部材２０を第１の断熱部材１０の凹部１１に収納する際に、折り込まれた周縁部２３によって第１の断熱部材１０と第２の断熱部材２０との間の間隙を減少させることができるので、間隙に結露が生じることを防止できる。   Furthermore, according to the heat insulating material of the present embodiment, when the second heat insulating member 20 is housed in the recess 11 of the first heat insulating member 10, the first heat insulating member 10 and the second heat insulating member 10 are separated by the folded peripheral edge portion 23. Since the gap with the heat insulating member 20 can be reduced, it is possible to prevent condensation from forming in the gap.

また、本実施形態の断熱材によれば、第１の断熱部材１０をウレタン材で形成し、第２の断熱部材２０を主にグラスウール２１からなる真空断熱材によって形成したので、汎用性の材料によって成形することができ、実用化に際して極めて有利である。   Moreover, according to the heat insulating material of this embodiment, since the 1st heat insulating member 10 was formed with the urethane material and the 2nd heat insulating member 20 was formed with the vacuum heat insulating material which mainly consists of glass wool 21, it is a versatile material. This is extremely advantageous for practical use.

図５乃至図７は本発明の他の実施形態を示すもので、図５は第２の断熱部材と被覆材の全体分解斜視図、図６は断熱材の全体分解斜視図、図７は断熱材の概略平面断面図を示す。尚、図１〜図４で示した断熱材と同一構成部分は同一符号をもって表し、その説明を省略する。   5 to 7 show another embodiment of the present invention. FIG. 5 is an entire exploded perspective view of the second heat insulating member and the covering material, FIG. 6 is an entire exploded perspective view of the heat insulating material, and FIG. A schematic plan sectional view of the material is shown. In addition, the same component as the heat insulating material shown in FIGS. 1-4 is shown with the same code | symbol, and the description is abbreviate | omitted.

本実施形態は、第１の断熱部材１０に厚さ方向に貫通した貫通部１２を設けた点で前記実施形態と異なる。   This embodiment is different from the above embodiment in that a penetrating portion 12 that penetrates the first heat insulating member 10 in the thickness direction is provided.

また、本実施形態は、被覆材３０を両端開口の筒状に形成し、この被覆材３０に第２の断熱部材２０を収納するように構成した点で前記実施形態と異なる。   In addition, the present embodiment is different from the above-described embodiment in that the covering material 30 is formed in a cylindrical shape having openings at both ends, and the second heat insulating member 20 is accommodated in the covering material 30.

第１の断熱部材１０は、厚さ方向に貫通した幅Ｘ’、高さＹ及び厚さＺ’の大きさからなる貫通部１２を、第１の断熱部材１０の中央領域に設けている。また、貫通部１２は、第１の断熱部材１０をプレス加工して打ち抜くことによって形成されている。さらに、第１の断熱部材１０はウレタン材から形成されている。   The first heat insulating member 10 is provided with a penetrating portion 12 having a width X ′, a height Y, and a thickness Z ′ penetrating in the thickness direction in the central region of the first heat insulating member 10. Moreover, the penetration part 12 is formed by pressing and punching the first heat insulating member 10. Furthermore, the 1st heat insulation member 10 is formed from the urethane material.

被覆材３０は樹脂製のフィルム形状であり、この被覆材３０を両端開口の筒状に形成する。このとき、被覆材３０の内側表面の大きさは幅Ｘ、高さＹ及び厚さＺであり、第２の断熱部材２０と同じ大きさとなるように形成されている。また、被覆材３０の外側表面の大きさは幅Ｘ’、高さＹ及び厚さＺ’であり、第１の断熱部材１０の貫通部１２と同じ大きさとなるように形成されている。   The covering material 30 is in the form of a resin film, and the covering material 30 is formed in a cylindrical shape having openings at both ends. At this time, the size of the inner surface of the covering material 30 is the width X, the height Y, and the thickness Z, and is formed to have the same size as the second heat insulating member 20. Further, the size of the outer surface of the covering material 30 is a width X ′, a height Y, and a thickness Z ′, and is formed so as to have the same size as the through portion 12 of the first heat insulating member 10.

このように構成された断熱材の製造工程及び作用について説明する。   The manufacturing process and operation of the heat insulating material configured as described above will be described.

まず、第２の断熱部材２０を被覆材３０の内側に収納して、被覆材３０によって第２の断熱部材２０の外側側面を被覆する。このとき、第２の断熱部材２０は、周縁部２３を折り込んで被覆材３０に収納されるようになっている。次に、被覆材３０に外側側面を被覆された第２の断熱部材２０を、第１の断熱部材１０の貫通部１２に収納することによって、断熱材が形成される。したがって、この断熱材は、金属製の板等の重量のある部品を用いることなく形成されるので、断熱材の厚さ寸法が小さくなるとともに、断熱材の軽量化が図られる。   First, the second heat insulating member 20 is housed inside the covering material 30, and the outer side surface of the second heat insulating member 20 is covered with the covering material 30. At this time, the second heat insulating member 20 is accommodated in the covering material 30 by folding the peripheral edge portion 23. Next, the second heat insulating member 20 whose outer side surface is covered with the covering material 30 is housed in the penetrating portion 12 of the first heat insulating member 10 to form a heat insulating material. Therefore, since this heat insulating material is formed without using heavy parts such as a metal plate, the thickness of the heat insulating material can be reduced and the heat insulating material can be reduced in weight.

このように本実施形態の断熱材によれば、フィルム形状の被覆材３０によって、第２の断熱部材２０の外側側面を被覆したので、被覆材３０によって第２の断熱部材２０全体を保護することができる。   Thus, according to the heat insulating material of this embodiment, since the outer side surface of the second heat insulating member 20 is covered with the film-shaped covering material 30, the entire second heat insulating member 20 is protected by the covering material 30. Can do.

また、本実施形態の断熱材によれば、第２の断熱部材２０を被覆材３０に収納する際に、折り込まれた周縁部２３によって第２の断熱部材２０と被覆材３０との間の間隙を減少させることができるので、間隙に結露が生じることを防止できる。   Further, according to the heat insulating material of the present embodiment, when the second heat insulating member 20 is accommodated in the covering material 30, the gap between the second heat insulating member 20 and the covering material 30 is caused by the folded peripheral edge portion 23. Therefore, it is possible to prevent the condensation from occurring in the gap.

また、被覆材３０の外側表面を第１の断熱部材１０の貫通部１２と同じ大きさに形成しているので、貫通部１２と被覆材３０との間の間隙を減少させることができるので、間隙に結露が生じることを一層防止できる。本実施形態のその他の作用及び効果は、図１〜図４で示した断熱材と同様である。   In addition, since the outer surface of the covering material 30 is formed in the same size as the penetrating portion 12 of the first heat insulating member 10, the gap between the penetrating portion 12 and the covering material 30 can be reduced. It is possible to further prevent condensation from forming in the gap. Other operations and effects of the present embodiment are the same as those of the heat insulating material shown in FIGS.

尚、前記実施形態において、図８及び図９に示すように、第１の断熱部材１０の凹部１１に、被覆材３０に外側側面を被覆された第２の断熱部材２０を収納するようにしても良い。また、前記実施形態において、第１の断熱部材１０の貫通部１２に第２の断熱部材２０を収納した後、被覆材３０によって第２の断熱部材２０の外側側面を被覆するようにしても良い。この場合における作用及び効果は、図１〜図７で示した断熱材と同様である。   In addition, in the said embodiment, as shown in FIG.8 and FIG.9, it was made to accommodate the 2nd heat insulation member 20 which coat | covered the outer side surface with the coating | covering material 30 in the recessed part 11 of the 1st heat insulation member 10. Also good. Moreover, in the said embodiment, after accommodating the 2nd heat insulation member 20 in the penetration part 12 of the 1st heat insulation member 10, you may make it coat | cover the outer side surface of the 2nd heat insulation member 20 with the coating | covering material 30. FIG. . The actions and effects in this case are the same as those of the heat insulating material shown in FIGS.

また、前記実施形態において、第１の断熱部材１０をウレタン材によって形成したがこれに限られない。例えば、ポリエチレンテレフタレート（以下、ＰＥＴという。）であっても良い。   Moreover, in the said embodiment, although the 1st heat insulation member 10 was formed with the urethane material, it is not restricted to this. For example, polyethylene terephthalate (hereinafter referred to as PET) may be used.

さらに、前記実施形態において、第２の断熱部材２０をグラスウール２１によって形成したがこれに限られない。例えば、ウレタン材やＰＥＴであっても良い。   Furthermore, in the said embodiment, although the 2nd heat insulation member 20 was formed with the glass wool 21, it is not restricted to this. For example, a urethane material or PET may be used.

また、前記実施形態の断熱材は、被覆材３０を樹脂製としたが、これに限られない。例えば、被覆材３０は金属製であっても良い。この場合、金属製の被覆材３０はフィルム状であり、被覆材３０を多く用いることなく断熱材を形成できることから、断熱材の軽量化を図ることができるので、断熱材が取り扱い易くなり、例えば自動販売機等の外箱に充填する等の場合において作業性を高めることができる。また、金属製の板等の高価な部品を多く用いないので、製造コストを抑えることができる。さらに、断熱材の厚さ寸法を小さくすることができるので、例えば自動販売機の断熱壁として断熱材を用いる場合に自動販売機本体の小型化を図ることができる。   Moreover, although the heat insulating material of the said embodiment made the coating | covering material 30 resin, it is not restricted to this. For example, the covering material 30 may be made of metal. In this case, the metal covering material 30 is in the form of a film, and since the heat insulating material can be formed without using a large amount of the covering material 30, the heat insulating material can be reduced in weight. Workability can be improved when filling an outer box of a vending machine or the like. Moreover, since many expensive parts, such as a metal board, are not used, manufacturing cost can be held down. Furthermore, since the thickness dimension of a heat insulating material can be made small, when using a heat insulating material as a heat insulation wall of a vending machine, for example, size reduction of a vending machine main body can be achieved.
