Description

本発明は、断熱扉及びこれを有する冷蔵庫に関する。 The present invention relates to a heat insulating door and a refrigerator having the same.

冷蔵庫の扉の意匠面として、鋼板やガラスの他、特許文献１に開示されるような樹脂が提案されている。特許文献１は、透明樹脂製の外板１７を有する扉を備えた冷蔵庫について、外板１７の内側に凹凸部を施した構造を開示する（請求項１，８、００１０，００１７、図４，５）。凹凸部によって外板１７に注がれた光が反射して立体感のある模様や色彩を出せるとしている。 In addition to steel plates and glass, resins as disclosed in Patent Document 1 have been proposed as design surfaces for refrigerator doors. Patent Document 1 discloses a structure in which an uneven portion is provided on the inside of the outer plate 17 of a refrigerator provided with a door having an outer plate 17 made of transparent resin (claims 1, 8, 0010, 0017, FIG. 4, FIG. 5). It is said that the uneven portion reflects the light poured on the outer plate 17 to produce a three-dimensional pattern and color.

樹脂製の外板を備える扉を製造する場合、薄いフィルムやフィルムよりは厚い別の板等のカバー材が外板に配されることがある。この場合、樹脂製の外板を適用する場合に特有の課題があることを本発明者らは見出した。樹脂製外板は、水分や気体といったいわゆるアウトガスを発することがある。物性や厚み等に起因して気体透過性の低い又はない外板及びカバー材の間にアウトガスが発生してしまうと、外板とカバー材との間に滞留して気泡を形成してしまう。 When manufacturing a door having a resin outer plate, a cover material such as a thin film or another plate thicker than the film may be arranged on the outer plate. In this case, the present inventors have found that there is a problem peculiar to the case of applying the outer plate made of resin. The resin outer plate may emit so-called outgas such as moisture and gas. If outgas is generated between the outer plate and the cover material having low or no gas permeability due to physical properties, thickness, etc., it stays between the outer plate and the cover material and forms air bubbles.

断熱扉２ａについて以下説明するが、その他の扉も少なくとも印刷物としての構成は同様にできる。 [Insulated door]
FIG. 2 is an exploded perspective view of a heat insulating door, which is an example of an object having a printed matter of a resin base material of the embodiment. FIG. 3 is an enlarged perspective view of a main part including the side end of the heat insulating door 3a of the embodiment. 4a and 4b are side sectional views of a main part of the heat insulating door of the embodiment and another embodiment, respectively, and are sectional views taken along the line II of FIG.
The heat insulating door 2a will be described below, but at least the other doors can be configured as printed matter in the same manner.

断熱扉２ａは、断熱扉２ａの表面(前面)に設けられた樹脂製の基材の一例である外板１０と、外板１０の周縁に設けられた扉枠２０と、外板１０の裏側に設けられた内板６０と、を備える。外板１０、扉枠２０、及び内板６０に囲まれた空間４０には、断熱材として例えば真空断熱材３０と発泡断熱材５０を設けることができる。 The heat insulating door 2a is an outer plate 10 which is an example of a resin base material provided on the surface (front surface) of the heat insulating door 2a, a door frame 20 provided on the peripheral edge of the outer plate 10, and a back side of the outer plate 10. The inner plate 60 provided in the door is provided. For example, a vacuum heat insulating material 30 and a foam heat insulating material 50 can be provided as heat insulating materials in the space 40 surrounded by the outer plate 10, the door frame 20, and the inner plate 60.

（外板１０）
外板１０は、断熱扉２ａの表面（前面）で意匠面を形成する部材である。外板１０は例えばＰＣ（ポリカーボネート）やＰＭＭＡ（アクリル）、ＡＢＳ（アクリロニトリルブタジエンスチレン共重合体）樹脂等、任意の樹脂を用いることができる。このため外板１０はアウトガスの発生源となる。外板１０の裏面には、外板１０に近い順に、印刷層８０ａ，８０ｂとカバー材９０の一例としての飛散防止フィルム９０とが配されている。 (Outer plate 10)
The outer plate 10 is a member that forms a design surface on the surface (front surface) of the heat insulating door 2a. Any resin such as PC (polycarbonate), PMMA (acrylic), and ABS (acrylonitrile butadiene styrene copolymer) resin can be used for the outer plate 10. Therefore, the outer plate 10 becomes a source of outgas. On the back surface of the outer plate 10, the print layers 80a and 80b and the shatterproof film 90 as an example of the cover material 90 are arranged in the order closer to the outer plate 10.

外板１０の板厚が薄いと、塗料中の溶剤によるケミカル割れ、乾燥時の熱による変形等、外観不良をおこしやすいため、樹脂厚みは１．０ｍｍ以上が望ましい。塗膜層やフィルムは外板１０の素材がＰＰ樹脂などの場合、密着性が十分でなくなるため、プライマー塗布やプラズマ加工などの下処理を行っても良い。 If the outer plate 10 is thin, appearance defects such as chemical cracking due to the solvent in the paint and deformation due to heat during drying are likely to occur. Therefore, the resin thickness is preferably 1.0 mm or more. When the material of the outer plate 10 of the coating film layer or film is PP resin or the like, the adhesiveness is not sufficient. Therefore, pretreatment such as primer coating or plasma processing may be performed.

（印刷層８０）
印刷層８０ａ，８０ｂは、インクの塗装、インクジェット印刷、着色又は印刷がなされたフィルムの貼付とすることができる。印刷層８０ａ，８０ｂとしては、透明な塗膜層や光輝材などを含ませてもよい。印刷層８０ａ，８０ｂ及びカバー材９０は、外板１０の表側でも裏側でも良い。印刷層８０ａ，８０ｂは主に樹脂であり、気体透過性を有する。 (Print layer 80)
The print layers 80a and 80b can be attached with ink-painted, inkjet-printed, colored or printed films. The printing layers 80a and 80b may include a transparent coating film layer, a brightening material, or the like. The printing layers 80a and 80b and the cover material 90 may be on the front side or the back side of the outer plate 10. The print layers 80a and 80b are mainly resins and have gas permeability.

図４ａ，４ｂに例示するように、ベース色やベース質感を表現する、断熱扉３ａの正面視の全域で略均一なフラット層として印刷層８０ａを形成する。一方、層状に印刷したフラット層ではなく、複数の点状、線状又は面状の着色、印刷又は塗装によって印刷層８０ｂを形成する。また、これとは逆に図４ｂに例示するように、印刷層８０ａ，８０ｂの特徴を互いに逆に形成してもよい。 As illustrated in FIGS. 4a and 4b, the print layer 80a is formed as a flat layer that is substantially uniform over the entire front view of the heat insulating door 3a that expresses the base color and the base texture. On the other hand, instead of the flat layer printed in layers, the printed layer 80b is formed by a plurality of dot-shaped, linear or planar coloring, printing or painting. On the contrary, as illustrated in FIG. 4b, the features of the print layers 80a and 80b may be formed in opposite directions to each other.

（カバー材９０）
カバー材９０は、外板１０の正面側又は裏面側の略全体を覆う面状又は板状の部材にすることができる。本実施形態では、印刷層８０ａ，８０ｂを挟んで外板１０の反対側に設けている。
カバー材９０が奏するべき機能に特に制限はないが、本実施形態では、外板１０が破損した場合に樹脂の飛散を抑制する、気体不透過性の飛散保護フィルムを用いている。その他、補強に用いたり断熱材３０，９０に対する剥離性を備えてもよい。カバー材９０は粘着層を備えており外板１０側に接着されている。例えば粘着層は、気体不透過性である。
カバー材９０は、外板１０や印刷層８０ａ，８０ｂをユーザが目視できるように透明、半透明、又は透光性を有することが好ましい。 (Cover material 90)
The cover material 90 can be a planar or plate-shaped member that covers substantially the entire front side or back surface side of the outer plate 10. In the present embodiment, the print layers 80a and 80b are provided on the opposite sides of the outer plate 10 with the print layers 80a and 80b interposed therebetween.
The function that the cover material 90 should perform is not particularly limited, but in the present embodiment, a gas-impermeable scattering protection film that suppresses the scattering of the resin when the outer plate 10 is damaged is used. In addition, it may be used for reinforcement or may have peelability to the heat insulating materials 30 and 90. The cover material 90 has an adhesive layer and is adhered to the outer plate 10 side. For example, the adhesive layer is gas impermeable.
The cover material 90 is preferably transparent, translucent, or translucent so that the outer plate 10 and the printed layers 80a and 80b can be visually recognized by the user.

なお、カバー材９０に印刷を施す等して、カバー材９０と印刷層８０とを一体化してもよい。 The cover material 90 and the printing layer 80 may be integrated by printing on the cover material 90 or the like.

（空隙Ｓ）
外板１０とカバー材９０との間の領域Ｖには、印刷層８０ａ，８０ｂ少なくともいずれかが複数の点状、線状又は面状に印刷されることで、気体が通過できる空隙Ｓが設けられている。外板１０や、カバー材９０の特に粘着層は気体不透過性であるため、破線で示すこれらの間の領域Ｖでアウトガスが発生すると、領域Ｖに期待が滞留しやすい。 (Void S)
In the region V between the outer plate 10 and the cover material 90, at least one of the printing layers 80a and 80b is printed in a plurality of dots, lines, or planes to provide a gap S through which gas can pass. Has been printed. Since the outer plate 10 and the cover material 90 in particular, the adhesive layer are gas impermeable, if outgas is generated in the region V between them shown by the broken line, expectations tend to stay in the region V.

図４の例では、空隙Ｓは、外板１０、印刷層８０ａ、印刷層８０ｂ、及びカバー材９０の一部又は全部によって延在方向断面（図４ａや図４ｂで描いた断面）が囲まれている。延在している空隙Ｓは、図３に例示するように断熱扉３ａの側端に達しており、ここで領域Ｖの外に連通している。すなわち外板１０のアウトガスが領域Ｖに生じても、空隙Ｓを通って領域Ｖの外に放出されることができる。よって、アウトガスによる意図しない気泡の生成、カバー材９０の浮き上がりや外板１０ひいては断熱扉の美感の低下を抑制できる。空隙Ｓは、外板１０とカバー材９０との間の領域Ｖに発生したアウトガスをこの領域外に逃がすことができる位置であればよい。 In the example of FIG. 4, the gap S is surrounded by a cross section in the extending direction (cross section drawn in FIGS. 4a and 4b) by a part or all of the outer plate 10, the printing layer 80a, the printing layer 80b, and the cover material 90. ing. The extending void S reaches the side end of the heat insulating door 3a as illustrated in FIG. 3, and communicates with the outside of the region V here. That is, even if the outgas of the outer plate 10 is generated in the region V, it can be discharged to the outside of the region V through the void S. Therefore, it is possible to suppress the unintended generation of air bubbles due to outgas, the floating of the cover material 90, and the deterioration of the aesthetic appearance of the outer panel 10 and thus the heat insulating door. The gap S may be a position where the outgas generated in the region V between the outer plate 10 and the cover material 90 can escape to the outside of this region.

このような空隙Ｓは、印刷層８０のデザインを調整することで設けることができる。例えば、非フラットな図４ａの印刷層８０ｂや図４ｂの印刷層８０ａの分布によって生じる空隙Ｓの好ましくはそれぞれが、断熱扉３ａの側端に達するようにしている。 Such a gap S can be provided by adjusting the design of the print layer 80. For example, preferably, each of the gaps S generated by the distribution of the non-flat print layer 80b of FIG. 4a and the print layer 80a of FIG. 4b reaches the side end of the heat insulating door 3a.

（カバー材９０の変形例）
カバー材９０に期待する機能を満たす範囲において、カバー材９０自身に空孔(不図示)を設けて、ところどころ孔があるもので外板１０を覆うようにしてもよい。このようにしても、外板１０とカバー材９０との間の領域Ｖの内外は、空孔を介して断熱扉２ａの厚み方向で連通することができるから、外板１０のアウトガスは領域Ｖ外に放出される。この場合、空隙Ｓは、断熱扉２ａの側端にまで延在していなくてもよい。 (Modification example of cover material 90)
As long as the function expected of the cover material 90 is satisfied, the cover material 90 itself may be provided with holes (not shown) so that the outer plate 10 is covered with holes in some places. Even in this way, since the inside and outside of the region V between the outer plate 10 and the cover material 90 can communicate with each other in the thickness direction of the heat insulating door 2a through the holes, the outgas of the outer plate 10 is the region V. It is released to the outside. In this case, the void S does not have to extend to the side end of the heat insulating door 2a.

カバー材９０自身に空孔を設ける場合、デザインによって空隙Ｓができる位置は異なり得るため、カバー材９０の略全域に亘って複数の空孔を設けることが好ましい。例えば、格子状に並んだ円形状の空孔を配置することができる。 When the cover material 90 itself is provided with holes, the position where the gap S is formed may differ depending on the design. Therefore, it is preferable to provide a plurality of holes over substantially the entire area of the cover material 90. For example, circular holes arranged in a grid pattern can be arranged.

（扉枠２０）
扉枠２０は、外板１０の四方の側面それぞれに沿った枠状の部材であり、外板１０の右側縁部に沿って形成される枠部材２１と、外板１０の左側縁部に沿って形成される枠部材２２と、外板１０の上側縁部に沿って形成される枠部材２３と、外板１０の下側縁部に沿って形成される枠部材２４と、が組み合わせて構成されている。扉枠２０は、例えば、ＡＢＳ樹脂やＰＰ（ポリプロピレン）樹脂で形成されている。 (Door frame 20)
The door frame 20 is a frame-shaped member along each of the four side surfaces of the outer plate 10, and is formed along the right edge of the outer plate 10 and along the left edge of the outer plate 10. 22 is formed in combination with the frame member 23 formed along the upper edge portion of the outer plate 10, and the frame member 24 formed along the lower edge portion of the outer plate 10. Has been done. The door frame 20 is made of, for example, ABS resin or PP (polypropylene) resin.

（真空断熱材３０、発泡断熱材５０、内板６０）
真空断熱材３０は、外板１０よりも左右方向（幅方向）の長さが短く形成されている。
空間４０内で発泡充填される発泡断熱材５０の発泡条件によっては、発泡圧で空隙Ｓが潰れてしまう虞がある。これを避けるため、外板１０と発泡断熱材５０とが接触しないよう、外板１０と発泡断熱材５０が接触する可能性のある場所へ保護部材１００を設置しておくことができる。保護部材１００としては、エプトシーラーの様なクッション材、ホットメルトやエラストマー等の樹脂材などを採用できる。 (Vacuum heat insulating material 30, foam heat insulating material 50, inner plate 60)
The vacuum heat insulating material 30 is formed to have a shorter length in the left-right direction (width direction) than the outer plate 10.
Depending on the foaming conditions of the foamed heat insulating material 50 that is foamed and filled in the space 40, the void S may be crushed by the foaming pressure. In order to avoid this, the protective member 100 can be installed at a place where the outer plate 10 and the foamed heat insulating material 50 may come into contact with each other so that the outer plate 10 and the foamed heat insulating material 50 do not come into contact with each other. As the protective member 100, a cushion material such as an Ept sealer, a resin material such as a hot melt or an elastomer, or the like can be adopted.

外板１０又はカバー材９０は、真空断熱材３０に対してホットメルト等、公知の接着剤で接着できる。真空断熱材３０は、接着剤に代えて又は追加して、扉枠２０によって固定されていてもよい。 The outer plate 10 or the cover material 90 can be adhered to the vacuum heat insulating material 30 with a known adhesive such as hot melt. The vacuum heat insulating material 30 may be fixed by the door frame 20 in place of or in addition to the adhesive.

内板６０は、断熱扉２ａの貯蔵室側に設けられた樹脂製（ＡＢＳなど）の板部材である。内板６０は、扉枠２０の裏面側の周縁部に固定されている。 The inner plate 60 is a resin (ABS or the like) plate member provided on the storage chamber side of the heat insulating door 2a. The inner plate 60 is fixed to the peripheral edge portion on the back surface side of the door frame 20.

以上説明した実施形態では、断熱扉を例としたが、カバー材を配した樹脂製の基材についても同様の技術的思想を適用できる。 In the above-described embodiment, the heat insulating door is taken as an example, but the same technical idea can be applied to the resin base material on which the cover material is arranged.
