以下、図面を用いて、本発明を実施するための形態(以下、実施形態と称する)を説明する。   DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention (hereinafter referred to as embodiments) will be described with reference to the drawings.

図１は、本発明の一実施形態に係わる冷蔵庫の全体構造を示す斜視図である。同図に示す冷蔵庫１は、その本体が内箱と外箱との間に真空断熱材を挟んで構成される断熱箱体３で構成され、この断熱箱体３は、天井となる上面壁を構成する上面板状部５、底面壁を構成する底面板状部７、左側壁を構成する左側板状部９、右側壁を構成する右側板状部１１および背面壁を構成する背面板状部１３で構成されている。   FIG. 1 is a perspective view showing the overall structure of a refrigerator according to an embodiment of the present invention. The refrigerator 1 shown in the figure is composed of a heat insulating box 3 having a main body sandwiching a vacuum heat insulating material between an inner box and an outer box. The heat insulating box 3 has a top wall serving as a ceiling. The upper surface plate-like portion 5 constituting the bottom wall, the bottom plate-like portion 7 constituting the bottom wall, the left-side plate-like portion 9 constituting the left-side wall, the right-side plate-like portion 11 constituting the right-side wall, and the back-side plate-like portion constituting the back wall. 13.

なお、図１においては、右側板状部１１、背面板状部１３および底面板状部７は、背後に隠れている。また、上面板状部５、底面板状部７、左側板状部９、右側板状部１１および背面板状部１３を総称して記載する場合には、単に板状部と称することにする。   In FIG. 1, the right side plate portion 11, the back plate portion 13, and the bottom plate portion 7 are hidden behind. Further, when the top plate-like portion 5, the bottom plate-like portion 7, the left-side plate-like portion 9, the right-side plate-like portion 11 and the back-side plate-like portion 13 are collectively described, they are simply referred to as plate-like portions. .

また、前記複数の板状部で上下左右および背部を囲まれた断熱箱体３の前面開口側には、観音開き式の冷蔵室扉１５、引き出し式の野菜室扉１７、引き出し式の製氷室扉１９、引き出し式の第１の冷凍室扉２１、および引き出し式の第２の冷凍室扉２３が取り付けられている。なお、第２の冷凍室扉２３は、製氷室扉１９の横に並んで設けられている。なお、これらの冷蔵室扉１５、野菜室扉１７、製氷室扉１９、第１の冷凍室扉２１および第２の冷凍室扉２３の奥の断熱箱体３内には、それぞれ冷蔵室、野菜室、製氷室、第１の冷凍室および第２の冷凍室が設けられているものである。   In addition, on the front opening side of the heat insulating box 3 surrounded by the plurality of plate-like portions in the up / down / left / right and back portions, a double-folding type refrigerator compartment door 15, a drawer-type vegetable compartment door 17, and a drawer-type ice making compartment door are provided. 19, A drawer-type first freezer compartment door 21 and a drawer-type second freezer compartment door 23 are attached. The second freezer compartment door 23 is provided next to the ice making compartment door 19. It should be noted that the refrigerator compartment door 15, the vegetable compartment door 17, the ice making compartment door 19, the first freezer compartment door 21, and the second freezer compartment door 23 have a refrigerator compartment and a vegetable inside the heat insulating box 3, respectively. A room, an ice making room, a first freezing room, and a second freezing room are provided.

図２は、図１に示した冷蔵庫１の横断面図である。具体的には、例えば図１の冷蔵庫１の第１の冷凍室扉２１の中程を水平に切断した横断面図である。同図に示すように、冷蔵庫１の断熱箱体３は、断面が左側板状部９、右側板状部１１および背面板状部１３で囲まれたコの字形に構成され、このコの字形状の断熱箱体３の前側の前面開口部に第２の冷凍室扉２１が取り付けられている。   FIG. 2 is a cross-sectional view of the refrigerator 1 shown in FIG. Specifically, for example, it is a cross-sectional view in which the middle of the first freezer compartment door 21 of the refrigerator 1 of FIG. 1 is cut horizontally. As shown in the figure, the heat insulating box 3 of the refrigerator 1 is configured in a U shape whose cross section is surrounded by a left plate portion 9, a right plate portion 11 and a back plate portion 13, and this U shape. A second freezer compartment door 21 is attached to the front opening on the front side of the heat insulating box 3 having a shape.

図３は、図２に示した冷蔵庫１の横断面図において点線の丸印Ａで囲まれた部分である左側板状部９の前端部と第２の冷凍室扉２１の左端部とが当接する角部の内部構造を詳細に示す断面図である。図３に示すように、第１の冷凍室扉２１は、扉外板３１と扉内板３３との間に真空断熱材３５を挟んで構成されている。   FIG. 3 is a cross-sectional view of the refrigerator 1 shown in FIG. 2, where the front end of the left plate-shaped portion 9 and the left end of the second freezer compartment door 21, which are portions surrounded by a dotted circle A, correspond to each other. It is sectional drawing which shows the internal structure of the corner | angular part which touches in detail. As shown in FIG. 3, the first freezer compartment door 21 is configured by sandwiching a vacuum heat insulating material 35 between a door outer plate 31 and a door inner plate 33.

通常、真空断熱材には、その製造上の理由から周囲に芯材を覆うラミネートフィルム等のフィルムの余長部分が生じる。図３に示す真空断熱材３５の端部はほぼ方形であるが、これは端部の余長部分、すなわち耳部を成形しながら折り曲げ真空断熱材面に密着させているためである。具体的には真空断熱材３５では、その耳部は真空断熱材３５端部から扉内板３３側に折り曲げ成形され、その面部分に密着するように成形される。すなわち図３では耳部は真空断熱材３５のガスケット部４１側面に密着することで、フィルムが重なり当該密着面部分を補強している。なお、この折り返し部分は、内部の接着剤により、密封状態が強固に保たれている。   Usually, in the vacuum heat insulating material, an extra length portion of a film such as a laminate film covering the core material is generated in the surroundings for manufacturing reasons. The end portion of the vacuum heat insulating material 35 shown in FIG. 3 has a substantially square shape because the extra length portion of the end portion, that is, the ear portion is bent and brought into close contact with the surface of the vacuum heat insulating material. Specifically, in the vacuum heat insulating material 35, the ear portion is bent from the end of the vacuum heat insulating material 35 toward the door inner plate 33 and is formed so as to be in close contact with the surface portion. That is, in FIG. 3, the ear portion is in close contact with the side surface of the gasket portion 41 of the vacuum heat insulating material 35, so that the film overlaps to reinforce the close contact surface portion. Note that the folded portion is firmly sealed by an internal adhesive.

また、冷蔵庫１の側壁部を構成する左側板状部９も同様に左側外板９１と左側内板９３との間に真空断熱材９５を挟んで構成されている。   Similarly, the left side plate-like portion 9 constituting the side wall portion of the refrigerator 1 is also configured by sandwiching a vacuum heat insulating material 95 between the left outer plate 91 and the left inner plate 93.

また、第１の冷凍室扉２１の内側は、左端部にガスケット４１が取り付けられ、また当該ガスケット４１の手前には、すなわち同図においてガスケット４１の右側には、第１の冷凍室の内部に向かうように斜めに折曲して大きく突出する突出部としてのスロート部４３が設けられる。このスロート部４３の内部には、発泡断熱材３７が充填される。このスロート部４３は、冷気の逃げ場を塞ぐことにより、冷気漏れ防止部として機能し、さらに冷凍効率を上げている。   In addition, a gasket 41 is attached to the left end of the inside of the first freezer compartment door 21, and in front of the gasket 41, that is, on the right side of the gasket 41 in FIG. A throat portion 43 is provided as a protruding portion that is bent obliquely so as to face and protrudes greatly. The throat portion 43 is filled with a foam heat insulating material 37. The throat portion 43 functions as a cold air leakage prevention portion by closing the cold air escape area, and further increases the refrigeration efficiency.

ガスケット４１は、左側板状部９の前端部に当接する端部にマグネット４５が取り付けられ、このマグネット４５により第１の冷凍室扉２１の端部は左側板状部９の前端部に磁着するようになっている。また、このマグネット４５の内側には、エアクッション部４７が設けられ、第１の冷凍室扉２１を閉じた時の左側板状部９に対する衝撃を緩衝するようになっている。   The gasket 41 has a magnet 45 attached to an end that abuts the front end of the left plate-shaped portion 9, and the magnet 45 causes the end of the first freezer compartment door 21 to be magnetically attached to the front end of the left plate-shaped portion 9. It is supposed to be. Further, an air cushion portion 47 is provided inside the magnet 45 so as to buffer the impact on the left plate portion 9 when the first freezer compartment door 21 is closed.

前記エアクッション部４７と第１の冷凍室扉２１の扉内板３３との間には、ガスケット取付部４９が設けられ、このガスケット取付部４９の内部にエアクッション部４７から伸び出ている矢尻状の差込部５１が差し込まれている。なお、このガスケット取付部４９は、扉内板３３と一体、例えば扉内板３３の延長として形成されるものであっても良い。   A gasket mounting portion 49 is provided between the air cushion portion 47 and the door inner plate 33 of the first freezer compartment door 21, and an arrowhead extending from the air cushion portion 47 inside the gasket mounting portion 49. The insertion part 51 of a shape is inserted. The gasket mounting portion 49 may be formed integrally with the door inner plate 33, for example, as an extension of the door inner plate 33.

また、ガスケット取付部４９とエアクッション部４７との間であって、ガスケット取付部４９の両側には、ひれ部５３、５５が取り付けられ、このひれ部５３、５５で第１の冷凍室からの冷気の漏洩を防止し、この漏洩冷気による第１の冷凍室扉２１の内部の結露を抑制している。   In addition, fin portions 53 and 55 are attached between the gasket attachment portion 49 and the air cushion portion 47 and on both sides of the gasket attachment portion 49, and the fin portions 53 and 55 are connected to the first freezer compartment. The leakage of cold air is prevented, and condensation inside the first freezer compartment door 21 due to the leaked cold air is suppressed.

図４および図５は、本発明および従来における上述した第１の冷凍室扉２１と左側板状部９との角部の温度特性を角部の構造の上に重複して示す図である。なお、図４および図５において、符号ａは、温度２２．６゜Ｃ、符号ｂは、温度１６．８゜Ｃ、符号ｃは、温度１１．０゜Ｃ、符号ｄは、温度５．２゜Ｃ、符号ｅは、温度―０．６゜Ｃ、符号ｆは、温度―６．４゜Ｃを示す点であり、これらと同じ温度を示す複数の点を連結した線で示す同じ温度帯がグラフとして示されている。   FIG. 4 and FIG. 5 are diagrams showing the temperature characteristics of the corners of the first freezer compartment door 21 and the left side plate-like portion 9 described above in the present invention and the prior art on the corner structure. 4 and 5, the symbol a is a temperature of 22.6 ° C., the symbol b is a temperature of 16.8 ° C., the symbol c is a temperature of 11.0 ° C., and the symbol d is a temperature of 5.2. ° C, symbol e is temperature -0.6 ° C, and symbol f is temperature -6.4 ° C, and the same temperature range indicated by a line connecting a plurality of points indicating the same temperature. Is shown as a graph.

まず、図５を参照して、従来の温度特性について説明すると、図５に示す従来の温度特性では、第１の冷凍室扉２１の真空断熱材は、符号１０１で示すように、第１の冷凍室扉２１の左端部まで延出してなく、手前のスロート部のところで終端している。従って、この従来における温度分布において、符号ａで示す温度２２．６゜Ｃと符号ｂで示す温度１６．８゜Ｃとの間の結露温度帯は、従来の真空断熱材のない角部に発生し、この角部に結露が発生する可能性を有していた。   First, the conventional temperature characteristic will be described with reference to FIG. 5. In the conventional temperature characteristic shown in FIG. 5, the vacuum heat insulating material of the first freezer compartment door 21 is the first as shown by reference numeral 101. It does not extend to the left end of the freezer compartment door 21, but terminates at the throat portion in front. Therefore, in this conventional temperature distribution, a dew condensation temperature zone between the temperature 22.6 ° C indicated by the symbol a and the temperature 16.8 ° C indicated by the symbol b is generated at the corner portion where the conventional vacuum heat insulating material is not provided. However, there was a possibility that condensation would occur at the corners.

これに対して、図４に示す本発明の実施形態では、第１の冷凍室扉２１の真空断熱材３５は、第１の冷凍室扉２１の左端部まで延出し、側壁部である左側板状部９内の真空断熱材９５の扉に向かって延出する先端部を覆うように延出している。従って、この本発明の実施形態における温度分布において、符号ａで示す温度２２．６゜Ｃと符号ｂで示す温度１６．８゜Ｃとの間の結露温度帯は、第１の冷凍室扉２１の真空断熱材３５内に発生し、この角部の結露温度帯は、真空断熱材３５内で塞がっており、すなわち真空断熱材３５内に閉じ込められていて、第１の冷凍室扉２１の端部に結露が発生する可能性が全く無いものとなっている。   On the other hand, in the embodiment of the present invention shown in FIG. 4, the vacuum heat insulating material 35 of the first freezer compartment door 21 extends to the left end portion of the first freezer compartment door 21 and is a left side plate that is a side wall portion. It extends so that the front-end | tip part extended toward the door of the vacuum heat insulating material 95 in the shape part 9 may be covered. Therefore, in the temperature distribution in the embodiment of the present invention, the dew condensation temperature zone between the temperature 22.6 ° C. indicated by the symbol a and the temperature 16.8 ° C. indicated by the symbol b is the first freezer compartment door 21. The condensation temperature zone at the corners is closed in the vacuum heat insulating material 35, that is, confined in the vacuum heat insulating material 35, and the end of the first freezer compartment door 21. There is no possibility of dew condensation on the part.

以上のように構成される本実施形態の冷蔵庫において、第１の冷凍室扉２１を構成する真空断熱材３５は、扉外板３１と扉内板３３との間に挟まれて、第１の冷凍室扉２１の左端部まで延出し、断熱箱体を構成する側壁部である左側板状部９内の真空断熱材９５の扉に向かって延出する先端部を覆うように当該先端部を超えて延出しているため、第１の冷凍室扉２１の左端部における断熱性能が向上するとともに、この部分に結露温度帯が閉じ込められ、結露が発生することも防止することができる。   In the refrigerator of the present embodiment configured as described above, the vacuum heat insulating material 35 constituting the first freezer compartment door 21 is sandwiched between the door outer plate 31 and the door inner plate 33, and the first Extending to the left end portion of the freezer compartment door 21, the tip end portion is covered so as to cover the tip end portion extending toward the door of the vacuum heat insulating material 95 in the left side plate-like portion 9 which is a side wall portion constituting the heat insulation box. Since it extends beyond it, the heat insulation performance in the left end part of the 1st freezer compartment door 21 improves, and a condensation temperature zone is confined in this part, and it can also prevent that condensation occurs.

なお、側壁部である左側板状部９内の真空断熱材９５の扉に向かって延出する先端部を覆うように当該先端部を超えて延出するとは、具体的には、第１の冷凍室扉２１の真空断熱材３５の左端部は、前記ガスケット４１のガスケット取付部４９の中心位置よりも例えば３ｍｍ以上外側に延出していることであり、これによりこの部分の断熱性能が向上できるとともに、この部分に結露が発生することも防止することができるのである。   In addition, extending beyond the front-end | tip part so that the front-end | tip part extended toward the door of the vacuum heat insulating material 95 in the left side plate-shaped part 9 which is a side wall part is specifically, 1st The left end portion of the vacuum heat insulating material 35 of the freezer compartment door 21 is extended to, for example, 3 mm or more outside the center position of the gasket mounting portion 49 of the gasket 41, whereby the heat insulating performance of this portion can be improved. At the same time, it is possible to prevent condensation from occurring in this portion.

また、冷気漏れ防止部として機能するスロート部４３の内部に発泡断熱材（ＥＰＳ等）が存在する構成の場合は、その限りではなく、スロート部４３にある発泡断熱材の延出する位置よりも外側に延出していることでも断熱性能の向上を期待できる。   In addition, in the case of a configuration in which a foam heat insulating material (EPS or the like) is present inside the throat portion 43 that functions as a cold air leakage prevention portion, it is not limited to this, and the position of the foam heat insulating material in the throat portion 43 extends. The heat insulation performance can also be improved by extending outward.

更に、上述したように、第１の冷凍室扉２１の真空断熱材３５を、その左端部がガスケット取付部４９の中心位置よりも外側に延出させて、第１の冷凍室扉２１の左端部まで延出させることにより、断熱箱体３の正面から見た大きさである正面視サイズに対する真空断熱材の被覆率を増大することができるものであり、第１の冷凍室扉２１と左側板状部９との角部の断熱性能を向上させることができ、ひいては冷蔵庫１の断熱性能を向上することができ、結露を防止することができる。   Further, as described above, the left end of the vacuum heat insulating material 35 of the first freezer compartment door 21 is extended outward from the center position of the gasket mounting portion 49, and the left end of the first freezer compartment door 21. It is possible to increase the coverage of the vacuum heat insulating material with respect to the front view size, which is the size seen from the front of the heat insulating box 3, by extending to the part, and the first freezer compartment door 21 and the left side The heat insulation performance of the corner | angular part with the plate-shaped part 9 can be improved, and by extension, the heat insulation performance of the refrigerator 1 can be improved and dew condensation can be prevented.
