Description

本発明は、内板と外板との間に真空断熱材を装着した冷蔵庫に関するものである。   The present invention relates to a refrigerator equipped with a vacuum heat insulating material between an inner plate and an outer plate.

近年、地球環境保護の視点より、省エネルギーや省資源に対して、様々な取り組みがなされている。家電製品においては、消費電力の削減による省エネルギー化や解体回収により再利用して、省資源化や環境汚染防止がはかられている。特に冷蔵庫では、断熱効率の良い真空断熱材の利用による省エネルギー化と、真空断熱材の解体回収による省資源化が求められている。   In recent years, various efforts have been made to save energy and resources from the viewpoint of protecting the global environment. Household appliances are reused through energy saving and dismantling and recovery by reducing power consumption, thereby saving resources and preventing environmental pollution. In particular, refrigerators are required to save energy by using vacuum heat insulating materials with good heat insulating efficiency and to save resources by dismantling and recovering vacuum heat insulating materials.

この真空断熱材料の再利用は、埋め立てや、焼却による環境汚染の抑制につながり、省資源の観点からも極めて重要である。   Reuse of this vacuum heat insulating material leads to suppression of environmental pollution caused by landfill and incineration, and is extremely important from the viewpoint of resource saving.

回収された冷蔵庫は破砕材料として搬入される。搬入された破砕材料が、種々の破砕機器を用いて機械的に破砕される。つぎに、破砕された金属類やゴム等の重い物は、振動コンベアと磁力選別とにより、鉄や非鉄金属およびゴム等に分類され、再利用や廃棄される。   The collected refrigerator is carried in as a crushed material. The crushed material carried in is mechanically crushed using various crushing devices. Next, crushed heavy objects such as metals and rubber are classified into iron, non-ferrous metal, rubber, and the like by a vibrating conveyor and magnetic sorting, and reused or discarded.

一方破砕された材料の内、内板や断熱材を構成する樹脂材料等の軽いものは、真空断熱材処理工程に送るため、破砕後、ダクトにより吸い出され、サイクロンに送られる。サイクロン内では、真空断熱材の芯材を形成しているガラス繊維と、ポリエステル樹脂で形成されている芯材をいれる袋や、発泡ウレタン樹脂の充填断熱材やABS樹脂等の樹脂で形成される内板等の材料に分別される。   On the other hand, light materials such as resin materials constituting the inner plate and the heat insulating material among the crushed materials are sucked out by a duct after being crushed and sent to a cyclone to be sent to the vacuum heat insulating material processing step. Inside the cyclone, it is made of glass fiber that forms the core material of the vacuum heat insulating material, a bag containing the core material made of polyester resin, a foamed urethane resin filled heat insulating material, or a resin such as ABS resin. Sorted into materials such as inner plates.

なお、芯材を形成するガラス繊維は、単に繊維の集綿体の状態、または集綿体を結合材で固めた状態のいずれかで用いている。次いで、真空断熱材のガラス繊維のみを分別回収する。回収された真空断熱材のガラス繊維は、再処理工程で、混入しているガラス繊維以外の材料や、破砕により細かく粉砕されたガラス繊維を不純物として除去して、所定長さ以上のガラス繊維が処理選別される。このようにして選別されたガラス繊維は、ガラス繊維の断熱材として再利用される。   In addition, the glass fiber which forms a core material is used in either a state of a fiber collection body or a state in which the collection body is hardened with a binder. Next, only the glass fiber of the vacuum heat insulating material is separated and collected. The recovered glass fiber of the vacuum heat insulating material is removed in the reprocessing step by removing the material other than the mixed glass fiber or the glass fiber finely crushed by the crushing as impurities. Process selected. The glass fiber thus selected is reused as a heat insulating material for the glass fiber.

樹脂製内箱と金属製外箱との間に発泡断熱材を充填した構成を有する冷蔵庫において、金属製外箱の背面に開口部を設け、この開口部を別の蓋材により封口し、発泡断熱材が金属製外箱の内面に設けられた潤滑性剥離層を介して設けられ、冷蔵庫の解体時には金属製外箱と樹脂製内箱とを接続している領域部を切断した後、開口部からピストンにより金属製外箱と発泡断熱材とを分離する方法が、特許文献1に開示されている。

本発明の参考例1の冷蔵庫について、図1〜図3を用いて説明する。図1は本発明の参考例1の冷蔵庫の外観を示す斜視図である。図2は同参考例の冷蔵庫の側面図である。図3は同参考例の冷蔵庫の側面の壁の断面図である。
( Reference Example 1 )
The refrigerator of the reference example 1 of this invention is demonstrated using FIGS. 1-3. FIG. 1 is a perspective view showing an appearance of a refrigerator according to Reference Example 1 of the present invention. FIG. 2 is a side view of the refrigerator of the reference example . FIG. 3 is a cross-sectional view of the side wall of the refrigerator of the reference example .

図1において、冷蔵庫1は、前面には扉部3があり、他の面は壁部2で囲われ、内部の温度維持ができるように構成されている。扉部3と壁部2とは、鉄板等で形成される外板4と、樹脂で形成される内板5と、これらの間にポリエステル樹脂繊維やガラス繊維を芯材6として形成されている真空断熱材7と、発泡ウレタン樹脂の充填断熱材8とを有して構成されている。なお、真空断熱材7には、図3に示すように外被材9のヒレ部10が周囲に設けられている。   In FIG. 1, the refrigerator 1 has the door part 3 in the front surface, and the other surface is enclosed by the wall part 2, and it is comprised so that an internal temperature can be maintained. The door portion 3 and the wall portion 2 are formed as an outer plate 4 formed of an iron plate or the like, an inner plate 5 formed of resin, and a polyester resin fiber or glass fiber as a core material 6 therebetween. It has a vacuum heat insulating material 7 and a filled heat insulating material 8 made of urethane foam resin. In addition, the vacuum heat insulating material 7 is provided with a fin portion 10 of an outer covering material 9 as shown in FIG.

また、外板4には、冷蔵庫1に設けられた真空断熱材7を適切に取り出すときの切り出し位置を示す凹形状のマーク11があり、冷蔵庫1を解体するときに、マーク11に沿って外板4を切断して真空断熱材7を取り出す。このマーク11は冷蔵庫1の外板4の原板からの切り出し、プレス成形等の過程において、マーク11を設けたい位置に対しプレス成形により設ける。   Further, the outer plate 4 has a concave mark 11 indicating a cut-out position when the vacuum heat insulating material 7 provided in the refrigerator 1 is properly taken out. The plate 4 is cut and the vacuum heat insulating material 7 is taken out. The mark 11 is provided by press molding at a position where the mark 11 is to be provided in the process of cutting out from the original plate of the outer plate 4 of the refrigerator 1 and press molding.

このマーク11は、真空断熱材7あるいはその構成材料を効率的にリサイクルするために冷蔵庫メーカーが決定する真空断熱材7切り出し位置を示すものであり、真空断熱材7の装着位置を示すものではない。真空断熱材7は、図2に点線で示すように壁部2の周囲より所定の間隔をあけて、かつ移動や、偏りが生じないように外板6と内板7との間において、外板6に接着固定されている。さらに、充填断熱材8を注入して、壁部2の断熱性を向上させることができる。この充填断熱材8は、用いても用いなくても良いが、用いない方が真空断熱材7の回収は容易となる。この構成は扉部3も同様である。   This mark 11 indicates the cutout position of the vacuum heat insulating material 7 determined by the refrigerator manufacturer in order to efficiently recycle the vacuum heat insulating material 7 or its constituent materials, and does not indicate the mounting position of the vacuum heat insulating material 7. . The vacuum heat insulating material 7 is placed between the outer plate 6 and the inner plate 7 at a predetermined interval from the periphery of the wall 2 as shown by a dotted line in FIG. The plate 6 is adhesively fixed. Furthermore, the heat insulating property of the wall part 2 can be improved by injecting the filling heat insulating material 8. The filled heat insulating material 8 may or may not be used, but the vacuum heat insulating material 7 can be easily recovered if not used. This configuration is the same for the door 3.

図1に示すように本参考例では、上記したように冷蔵庫1の解体切断時に真空断熱材7あるいはその構成材料を効率的にリサイクルするために冷蔵庫メーカーが決定する真空断熱材7切り出し位置を示すものであり、このマーク11を結ぶ線上を切断することで、真空断熱材7または真空断熱材7を構成する材料を効率的に取り出せるように冷蔵庫1の壁部2を切断できる。 As shown in FIG. 1, in this reference example , as described above, the vacuum heat insulating material 7 cutting position determined by the refrigerator manufacturer in order to efficiently recycle the vacuum heat insulating material 7 or its constituent materials when the refrigerator 1 is disassembled and cut is shown. The wall portion 2 of the refrigerator 1 can be cut so that the vacuum heat insulating material 7 or the material constituting the vacuum heat insulating material 7 can be efficiently taken out by cutting the line connecting the marks 11.

この場合、真空断熱材7の真空包装を損傷することなく冷蔵庫1の壁部2を切断しても良いし、真空断熱材7を構成する材料を効率的に取り出すことを考慮して例えば真空断熱材7の中央部にマーク11を設けて切断を行い、真空断熱材7の真空包装を損傷して取り出しても良い。   In this case, the wall portion 2 of the refrigerator 1 may be cut without damaging the vacuum packaging of the vacuum heat insulating material 7, or in consideration of efficiently taking out the material constituting the vacuum heat insulating material 7. The mark 11 may be provided at the center of the material 7 for cutting, and the vacuum packaging of the vacuum heat insulating material 7 may be damaged and taken out.

切断後は、既知の任意の方法で、外板4、内板5および充填断熱材8を除去する等により、真空断熱材7あるいは真空断熱材7を構成する材料を効率的に回収することができる。なお、充填断熱材8を用いない構成の場合は、内板5の切断をしなくても、外板4と真空断熱材7を冷蔵庫1より分離することができる。   After the cutting, the vacuum heat insulating material 7 or the material constituting the vacuum heat insulating material 7 can be efficiently recovered by removing the outer plate 4, the inner plate 5 and the filling heat insulating material 8 by any known method. it can. In the case of a configuration that does not use the filling heat insulating material 8, the outer plate 4 and the vacuum heat insulating material 7 can be separated from the refrigerator 1 without cutting the inner plate 5.

また、マーク11は外板4に対し凹形状であるため、冷蔵庫1の生産・運搬、家庭への搬入・設置時等において、冷蔵庫1が他のものと接触した場合、マーク11に傷が発生し冷蔵庫1の外観が低下することを防止することができる効果が得られる。   Further, since the mark 11 has a concave shape with respect to the outer plate 4, if the refrigerator 1 comes into contact with other things during production / transportation of the refrigerator 1, loading / installing into the home, etc., the mark 11 is damaged. And the effect which can prevent that the external appearance of the refrigerator 1 falls is acquired.

壁部2の切断手段については特に限定はなく、切断砥石、切断のこぎり、レーザーまたは高圧水等の既知の設備を用いることができる。いずれの切断手段を用いても、真空断熱材7あるいは真空断熱材7を構成する材料を効率的に取り出す位置については、マーク11により容易に判断できる。   The cutting means for the wall 2 is not particularly limited, and known equipment such as a cutting grindstone, a cutting saw, a laser, or high-pressure water can be used. Whichever cutting means is used, the position at which the vacuum heat insulating material 7 or the material constituting the vacuum heat insulating material 7 is efficiently taken out can be easily determined by the mark 11.

切断時においては、冷蔵庫1の全体を回転させれば容易に各面の切断加工ができ、外板4、内板5および充填断熱材8を除去し、真空断熱材7あるいは真空断熱材7を構成する材料を取り出すことができる。また、マーク11は、外板4の作製時にプレス成形等により簡単に作製することができ、マーク11は凹形状を有しているため真空断熱材7の位置決めが非常に楽になる効果も得られる。   At the time of cutting, if the entire refrigerator 1 is rotated, each surface can be cut easily, and the outer plate 4, the inner plate 5 and the filling heat insulating material 8 are removed, and the vacuum heat insulating material 7 or the vacuum heat insulating material 7 is removed. The constituent material can be taken out. Further, the mark 11 can be easily manufactured by press molding or the like when the outer plate 4 is manufactured. Since the mark 11 has a concave shape, the effect of facilitating the positioning of the vacuum heat insulating material 7 can be obtained. .

このマーク12は、冷蔵庫1の外板4の原板からの切り出し、プレス成形等の過程において、マーク12を設けたい位置に対しプレス成形等により設ける。このマーク12は真空断熱材7あるいはその構成材料を効率的にリサイクルするために冷蔵庫メーカーが決定する真空断熱材7切り出し方向を示すものであり、真空断熱材7の装着位置を示すものではない。   This mark 12 is provided by press molding or the like at a position where the mark 12 is to be provided in the process of cutting out from the original plate of the outer plate 4 of the refrigerator 1 and press molding. This mark 12 indicates the cut-out direction of the vacuum heat insulating material 7 determined by the refrigerator manufacturer in order to efficiently recycle the vacuum heat insulating material 7 or its constituent materials, and does not indicate the mounting position of the vacuum heat insulating material 7.

真空断熱材7は、図4に点線で示すように、壁部2の周囲より所定の間隔をあけて、かつ移動や、偏りが生じないように外板6と内板7との間において、外板6に接着固定されている。さらに、充填断熱材8を注入して、壁部2の断熱性を向上させることができる。この充填断熱材8は、用いても用いなくても良いが、用いない方が真空断熱材7の回収は容易となる。この構成は扉部3も同様である。   As shown by a dotted line in FIG. 4, the vacuum heat insulating material 7 is spaced from the periphery of the wall portion 2 by a predetermined interval and between the outer plate 6 and the inner plate 7 so as not to move or be biased. The outer plate 6 is fixed by adhesion. Furthermore, the heat insulating property of the wall part 2 can be improved by injecting the filling heat insulating material 8. The filled heat insulating material 8 may or may not be used, but the vacuum heat insulating material 7 can be easily recovered if not used. This configuration is the same for the door 3.

In the case of a configuration that does not use the filling heat insulating material 8, the outer plate 4 and the vacuum heat insulating material 7 can be separated from the refrigerator 1 without cutting the inner plate 5. Moreover, since the mark 12 is provided on the back surface 15 and the top surface 13 and the bottom surface 14 of the refrigerator 1 and is hardly noticeable to consumers, the effect that the design of the refrigerator 1 is not uncomfortable is obtained.

壁部2の切断手段については特に限定はなく、切断砥石、切断のこぎり、レーザーまたは高圧水等の既知の設備を用いることができる。いずれの切断手段を用いても、真空断熱材7あるいは真空断熱材7を構成する材料を効率的に取り出す位置についてはマーク12より容易に判断できる。   The cutting means for the wall 2 is not particularly limited, and known equipment such as a cutting grindstone, a cutting saw, a laser, or high-pressure water can be used. Whichever cutting means is used, the position where the vacuum heat insulating material 7 or the material constituting the vacuum heat insulating material 7 is efficiently taken out can be easily determined from the mark 12.

切断時においては、冷蔵庫1の全体を回転させれば容易に各面の切断加工ができ、外板4、内板5および充填断熱材8を除去し、真空断熱材7あるいは真空断熱材7を構成する材料を取り出すことができる。また、マーク12は、外板4の作製時にプレス成形等により簡単に作製することができる。   At the time of cutting, if the entire refrigerator 1 is rotated, each surface can be cut easily, and the outer plate 4, the inner plate 5 and the filling heat insulating material 8 are removed, and the vacuum heat insulating material 7 or the vacuum heat insulating material 7 is removed. The constituent material can be taken out. The mark 12 can be easily produced by press molding or the like when the outer plate 4 is produced.

尚、本実施の形態においては、扉部3にマーク12を設けることはしていないが、冷蔵庫1としての外観が問題なければ扉部3に設けてもかまわない。また、真空断熱材7が冷蔵庫1側面の壁部2に設置された場合の真空断熱材7の切り出し位置を示したが、冷蔵庫1の天面13、底面14、背面15に真空断熱材7が設けられた場合には、各面に真空断熱材7の切り出しマークを設けてもかまわないし、マークが目立つ部位に関しては目立たない部位に設けることを行っても問題はない。   In addition, in this Embodiment, although the mark 12 is not provided in the door part 3, if the external appearance as the refrigerator 1 does not have a problem, you may provide in the door part 3. Moreover, although the cut-out position of the vacuum heat insulating material 7 when the vacuum heat insulating material 7 is installed on the wall portion 2 on the side surface of the refrigerator 1 is shown, the vacuum heat insulating material 7 is provided on the top surface 13, the bottom surface 14, and the back surface 15 of the refrigerator 1. In the case of being provided, a cut mark of the vacuum heat insulating material 7 may be provided on each surface, and there is no problem even if the mark is conspicuous in a portion that is not conspicuous.

A refrigerator according to Reference Example 2 of the present invention will be described with reference to FIGS. FIG. 8 is a perspective view showing the inner plate of the refrigerator of Reference Example 2 of the present invention, and FIG. 9 is a cross-sectional view of the main part of the rear lower part of the refrigerator of Reference Example .

図8において、冷蔵庫1の内板5に設けられた真空断熱材7の切り出し位置を示すマーク16は、マーク16に沿って内板5をカッター等により切断することにより真空断熱材7を取り出すためのものである。このマーク16は、冷蔵庫1の内板5の真空成形等の過程において、真空成形用金型のマーク16を設けたい位置に対しマーク16の形状の加工を行うことにより簡単に内板5に設けることができる。   In FIG. 8, the mark 16 indicating the cut-out position of the vacuum heat insulating material 7 provided on the inner plate 5 of the refrigerator 1 is used to take out the vacuum heat insulating material 7 by cutting the inner plate 5 with a cutter or the like along the mark 16. belongs to. This mark 16 is simply provided on the inner plate 5 by processing the shape of the mark 16 at a position where the mark 16 of the vacuum forming die 16 is to be provided in the process of vacuum forming the inner plate 5 of the refrigerator 1. be able to.

このマーク16は、真空断熱材7あるいはその構成材料を効率的にリサイクルするために冷蔵庫メーカーが決定する真空断熱材7切り出し位置を示すものであり、真空断熱材7の装着位置を示すものではない。   This mark 16 indicates the cutout position of the vacuum heat insulating material 7 determined by the refrigerator manufacturer in order to efficiently recycle the vacuum heat insulating material 7 or its constituent materials, and does not indicate the mounting position of the vacuum heat insulating material 7. .

真空断熱材7は、図9に示す様に外板6と内板7との間において、内板5に接着固定されている。さらに、充填断熱材8を注入して、壁部2の断熱性を向上させることができる。この充填断熱材8は、用いても用いなくても良いが、用いない方が真空断熱材7の回収は容易となる。この構成は扉部3も同様である。   The vacuum heat insulating material 7 is bonded and fixed to the inner plate 5 between the outer plate 6 and the inner plate 7 as shown in FIG. Furthermore, the heat insulating property of the wall part 2 can be improved by injecting the filling heat insulating material 8. The filled heat insulating material 8 may or may not be used, but the vacuum heat insulating material 7 can be easily recovered if not used. This configuration is the same for the door 3.

図8に示すように本参考例では、上記したように冷蔵庫1の解体切断時に真空断熱材7あるいはその構成材料を効率的にリサイクルするために真空断熱材7切り出し位置を示すものであり、このマーク16を結ぶ線上あるいはマーク16に沿ってカッター等で内板5を切断することで、真空断熱材7または真空断熱材7を構成する材料を効率的に取り出すことができる。 As shown in FIG. 8, in this reference example , as described above, the vacuum heat insulating material 7 is cut out in order to efficiently recycle the vacuum heat insulating material 7 or its constituent materials when the refrigerator 1 is disassembled and cut. By cutting the inner plate 5 with a cutter or the like on the line connecting the marks 16 or along the marks 16, the vacuum heat insulating material 7 or the material constituting the vacuum heat insulating material 7 can be efficiently taken out.

この場合、真空断熱材7の真空包装を損傷することなく内板5切断しても良いし、真空断熱材7を構成する材料を効率的に取り出すことを考慮して例えば真空断熱材7の芯材の位置にマーク16を設けて切断を行い、真空断熱材7の真空包装を損傷して取り出しても良い。   In this case, the inner plate 5 may be cut without damaging the vacuum packaging of the vacuum heat insulating material 7, and the core of the vacuum heat insulating material 7 is taken into consideration, for example, in view of efficiently removing the material constituting the vacuum heat insulating material 7. The mark 16 may be provided at the position of the material to perform cutting, and the vacuum packaging of the vacuum heat insulating material 7 may be damaged and taken out.

切断後は、任意の方法で、真空断熱材7に付着している充填断熱材8、内板5を除去する等により、真空断熱材7あるいは真空断熱材7を構成する材料を効率的に回収することができる。   After cutting, the insulating material 8 and the material constituting the vacuum insulating material 7 are efficiently recovered by removing the filling insulating material 8 and the inner plate 5 attached to the vacuum insulating material 7 by an arbitrary method. can do.

また、マーク16は内板5の真空成形時にその金型を加工することにより簡単に作製することができ、またその形状は内板5とほぼ同等の凸凹形状も有することができる効果も得られる。   Further, the mark 16 can be easily manufactured by processing the mold during vacuum forming of the inner plate 5, and the shape can also have an uneven shape substantially the same as that of the inner plate 5. .

内板5の切断手段については特に限定はなく、カッター、切断砥石、切断のこぎり、レーザーまたは高圧水等の既知の設備を用いることができる。いずれの切断手段を用いても、真空断熱材7あるいは真空断熱材7を構成する材料を効率的に取り出す位置については内板5に設けたマーク16により容易に判断できる。   The cutting means for the inner plate 5 is not particularly limited, and known equipment such as a cutter, a cutting grindstone, a cutting saw, a laser, or high-pressure water can be used. Whichever cutting means is used, the position where the vacuum heat insulating material 7 or the material constituting the vacuum heat insulating material 7 is efficiently taken out can be easily determined by the mark 16 provided on the inner plate 5.

以上のように、本発明にかかる冷蔵庫は、真空断熱材あるいは真空断熱材を構成する材料を再利用しやすい形状で容易に回収することができる効果が得られ、更に、真空断熱材は、破砕分別と再処理により回収する方法より、安価に再利用することができるとともに、破砕により回収しきれない材料の廃棄や焼却処理による環境汚染も抑制することが可能となるので、真空断熱材の様に内部に充填され別途回収が必要なものを有する断熱箱体を備えた製品にも適用できる。   As described above, the refrigerator according to the present invention can obtain an effect of easily collecting the vacuum heat insulating material or the material constituting the vacuum heat insulating material in a shape that can be easily reused. It can be reused at a lower cost than the method of collection by separation and reprocessing, and it can also suppress environmental pollution due to disposal of materials that cannot be recovered by crushing or incineration. It can also be applied to a product provided with a heat insulation box that is filled inside and needs to be collected separately.
