Description
本発明は、断熱材として硬質ウレタンフォームと真空断熱材とを併用した冷蔵庫に関する。 The present invention relates to a refrigerator in which a rigid urethane foam and a vacuum heat insulating material are used in combination as a heat insulating material.
冷蔵庫の断熱材としては、硬質ウレタンフォームが主として用いられてきたが、近年、硬質ウレタンフォームより断熱性能の優れた真空断熱材を使用するケースが増加している。真空断熱材とは、芯材を外被材で覆って内部を減圧、封止したものであり、冷蔵庫に使用されるものは通常パネル状をなしている。 Rigid urethane foam has been mainly used as a heat insulating material for refrigerators, but in recent years, there are an increasing number of cases using vacuum heat insulating materials having better heat insulating performance than hard urethane foam. The vacuum heat insulating material is a material in which a core material is covered with an outer covering material and the inside is decompressed and sealed. What is used in a refrigerator usually has a panel shape.
真空断熱材の芯材及び外皮材としては種々のものが使用され、外皮材としては、ポリエステルフィルムやナイロンフィルム、ポリエチレンフィルム等の複合ラミネートフィルム等が多く使用されているが、芯材に例えば無機粉末が使用される場合もあり、このような異種材料の組合せからなるためにリサイクルが困難であり、通常は冷蔵庫から取り外した後、埋立や焼却により処分されている。 Various materials are used as the core material and outer skin material of the vacuum heat insulating material. As the outer skin material, a composite laminate film such as a polyester film, a nylon film, and a polyethylene film is often used. In some cases, powder is used, and it is difficult to recycle because it consists of such a combination of different materials. Usually, it is removed from the refrigerator and then disposed of by landfill or incineration.
これに鑑みて真空断熱材のリサイクル率を向上させるために、例えば、特開２００２−１８８７９１号公報には、ポリエステル集綿体等を芯材とし、ダイヤモンドライクカーボンの薄膜を固着したラミネートフィルムとからなる外被材から構成された真空断熱材を冷蔵庫に使用すること、及び使用している真空断熱材の材料種別を冷蔵庫に表示することが提案されている。 In view of this, in order to improve the recycling rate of the vacuum heat insulating material, for example, Japanese Patent Application Laid-Open No. 2002-188791 discloses a laminate film having a polyester cotton collection body or the like as a core material and a diamond-like carbon thin film fixed thereto. It has been proposed to use a vacuum heat insulating material composed of a covering material to be used in a refrigerator, and to display the material type of the vacuum heat insulating material used in the refrigerator.
しかしながら、断熱材として真空断熱材を単独で用いることは強度等の面から困難であり、例えば特開平１０−２０５９９５号公報に記載されているように、硬質ウレタンフォームと併用されているのが現状である。 However, it is difficult to use a vacuum heat insulating material alone as a heat insulating material in terms of strength and the like. For example, as described in JP-A-10-205995, it is currently used in combination with a rigid urethane foam. It is.
真空断熱材を廃棄するにしても、リサイクルするにしても、リサイクル工場での冷蔵庫の解体時に分別する必要があり、手作業で取り外している。ところが、上記のように真空断熱材とウレタンフォームが併用されている状況下で、真空断熱材を使用する機種が増加し、使用枚数も増加すると、どの部分に真空断熱材が埋設されているかの判別が困難となり、取り外し作業に支障を来たすという問題が生じつつある。 Whether the vacuum insulation material is discarded or recycled, it is necessary to separate it when the refrigerator is dismantled in the recycling factory, and it is removed manually. However, in the situation where vacuum insulation and urethane foam are used together as described above, when the number of models that use vacuum insulation increases and the number of used sheets increases, in which part the vacuum insulation is embedded. Discrimination becomes difficult, and there is a problem that the removal work is hindered.
本発明は上記に鑑みてなされたものであり、冷蔵室又は冷凍室の断熱材として硬質ウレタンフォームと真空断熱材とを併用した冷蔵庫であって、解体の際に真空断熱材の埋設位置の判断が容易であり、外し残しが生じない冷蔵庫を提供することを目的とする。 The present invention has been made in view of the above, and is a refrigerator in which a hard urethane foam and a vacuum heat insulating material are used in combination as a heat insulating material for a refrigerator compartment or a freezer compartment, and the determination of the burying position of the vacuum heat insulating material at the time of dismantling An object of the present invention is to provide a refrigerator that is easy to remove and does not leave undetached.

図１及び図２は硬質ウレタンフォームと真空断熱材を併用した冷蔵庫の例を示す縦断面図であり、図１は正面から見た図、図２は側面から見た図である。両図において、符号１は冷蔵室、符号２は野菜室、符号３は冷凍室、符号４は硬質ウレタンフォーム、符号５は真空断熱材、矢印は冷気の流動方向を示す。
1 and 2 are longitudinal sectional views showing an example of a refrigerator in which a rigid urethane foam and a vacuum heat insulating material are used together. FIG. 1 is a view seen from the front, and FIG. 2 is a view seen from the side. In both figures,
これらの図に示されたように、本例の冷蔵庫においては、両側面に各１枚、背面に１枚、天井面に１枚、冷凍庫扉（最下段）に１枚の真空断熱材が硬質ウレタンフォームに埋設されている。 As shown in these figures, in the refrigerator of this example, one vacuum heat insulating material is hard on the both sides, one on the back, one on the ceiling, and one on the freezer door (bottom level). Embedded in urethane foam.
このような冷蔵庫の真空断熱材の埋設位置を示すために、例えば図３に示すようなラベルを冷蔵庫のキャビネット背面等に貼付する。 In order to show the burying position of the vacuum heat insulating material of such a refrigerator, for example, a label as shown in FIG.
本例のラベルには、真空断熱材の埋設位置と共にその枚数、及び埋設位置を示す図が併記されている。このように、埋設位置と共に埋設枚数も記載することにより、１の面に複数の真空断熱材が埋設されている場合に、外し残しを防止することができる。また、本図に示すような簡単な図を併記することにより、埋設位置を正確に、かつ直感的に理解させることが可能となる。但し、図３に示したラベルの表示項目や表示の仕方は一例であり、本発明は、これに限定されるものではない。 In the label of this example, a drawing showing the number of the vacuum heat insulating material as well as the number of the vacuum heat insulating material and the position where the vacuum heat insulating material is embedded is shown. Thus, by describing the number of burials as well as the burial position, when a plurality of vacuum heat insulating materials are buried in one surface, it is possible to prevent unremoved parts. In addition, by adding a simple diagram as shown in this figure, it is possible to accurately and intuitively understand the embedded position. However, the display items and display methods of the labels shown in FIG. 3 are merely examples, and the present invention is not limited to these.
埋設位置等の表示方法の例としては、上記のようなラベルを付すること以外に、刻印や印刷を冷蔵庫に直接施すことが挙げられる。 As an example of the display method of the embedding position or the like, in addition to attaching the label as described above, stamping or printing can be directly performed on the refrigerator.
上記したラベル等による埋設位置等の表示位置としては、キャビネット背面等の意匠を損なわない場所が好ましい。 As a display position such as an embedding position by the above-described label or the like, a place where the design such as the back of the cabinet is not impaired is preferable.
