Reference numeral 5 denotes a refrigerator compartment door. Reference numeral 6 denotes a freezer compartment door (ice making compartment door 6a, first freezer compartment door 6c, second freezer compartment door 6c). Reference numeral 7 denotes a vegetable compartment door.

尚、最近の冷蔵庫においては、凝縮器を特別に準備しないで放熱パイプを冷蔵庫本体１の外郭を構成する側板及び背面板の内側（発泡断熱材側）に取付けて、凝縮器の代わりをさせている。   In recent refrigerators, a heat radiating pipe is attached to the inside of the side plate and the back plate (foam insulation side) constituting the outer shell of the refrigerator body 1 without preparing a condenser in particular, so as to replace the condenser. Yes.

符号１１は、庫内ファンであり、冷却器８で冷却された冷気を冷蔵室２，冷凍室３，野菜室４に強制循環する。また、それぞれの貯蔵室は、冷気量を制御するダンパー，温度調節器等を伴って設定温度に冷却する。   Reference numeral 11 denotes an internal fan that forcibly circulates the cold air cooled by the cooler 8 to the refrigerator compartment 2, the freezer compartment 3, and the vegetable compartment 4. Each storage room is cooled to a set temperature with a damper, a temperature controller, and the like for controlling the amount of cool air.

冷蔵室扉５は、一側が冷蔵庫箱体１２に上ヒンジピン１３と下ヒンジピン１４に軸支され、ハンドル１５を操作することで回動（開閉）自在に取付けられている。   One side of the refrigerator compartment door 5 is pivotally supported on the refrigerator box 12 by an upper hinge pin 13 and a lower hinge pin 14, and is attached to be freely rotatable (openable / closable) by operating a handle 15.

符号１６は、外箱１７，発泡断熱材１８等を伴って冷蔵庫箱体１２を構成する内箱である。この内箱１６は、先の冷蔵室２の壁面を構成している。   Reference numeral 16 denotes an inner box that constitutes the refrigerator box 12 with the outer box 17, the foam insulation 18, and the like. This inner box 16 constitutes the wall surface of the previous refrigerator compartment 2.

符号１９は、冷蔵室扉５の一部を構成する扉内板である。この扉内板１９は、瓶や缶等の貯蔵物を収納することができる扉収納容器２０を有している。扉収納容器２０は、扉内板１９の両側に扉内板１９と一体に形成された凸部２２と棚部２３に、図の如くポケット部材２１が懸架される構成である。   Reference numeral 19 denotes a door inner plate constituting a part of the refrigerator compartment door 5. The door inner plate 19 has a door storage container 20 that can store stored items such as bottles and cans. The door storage container 20 has a configuration in which a pocket member 21 is suspended on both sides of a door inner plate 19 on a convex portion 22 and a shelf portion 23 formed integrally with the door inner plate 19 as shown in the figure.

そして、扉収納容器２０は図３に示すように、扉閉時、冷蔵室２側に１５０〜２００mm位入り込んでいる。   As shown in FIG. 3, the door storage container 20 enters about 150 to 200 mm on the refrigerator compartment 2 side when the door is closed.

すなわち、扉内板１９の凸部２２と内箱１６側縁（貯蔵室の側壁）は、隙間２４（スロート寸法）を介して重合している。冷蔵庫の設計に当たり、この隙間２４の設定は非常に重要である。なぜならば、隙間２４は狭い空間として、冷蔵室２内の冷気と、庫外の空気との熱の授受を抑制するものである。扉内板１９の凸部２２と内箱１６側壁とが重合する隙間２４（スロート寸法）は、６.０〜７.０mmに設定される。これは、内箱１６側壁と凸部２２の距離が、扉下がりにより変位した状態における隙間２４の最小許容値（３.５mm）を考慮した寸法よりも小さく設定したものである。   That is, the convex portion 22 of the door inner plate 19 and the side edge of the inner box 16 (side wall of the storage chamber) are overlapped via the gap 24 (throat dimension). In designing the refrigerator, the setting of the gap 24 is very important. This is because the gap 24 is a narrow space and suppresses transfer of heat between the cold air in the refrigerator compartment 2 and the air outside the refrigerator. A gap 24 (throat dimension) where the convex portion 22 of the door inner plate 19 and the side wall of the inner box 16 overlap is set to 6.0 to 7.0 mm. In this case, the distance between the side wall of the inner box 16 and the convex portion 22 is set to be smaller than the dimension considering the minimum allowable value (3.5 mm) of the gap 24 in a state of being displaced by the door lowering.

なお、本実施例の場合、隙間２４が従来の９.０mmでなく６.０〜７.０mmと狭められている。このことにより、貯蔵室内部と外部との気体の移動の抑制効果は一段と向上されるとともに、扉収納容器２０の幅は隙間２４を詰めた分拡大される。   In the present embodiment, the gap 24 is narrowed to 6.0 to 7.0 mm instead of the conventional 9.0 mm. As a result, the effect of suppressing the movement of gas between the inside of the storage chamber and the outside is further improved, and the width of the door storage container 20 is increased by filling the gap 24.

一方、凸部２２の厚みＷ１寸法は１５mm位に作られている。この厚み寸法１５mmは、先に記述した隙間２４での気体の移動の抑制のために、扉内板の一体成形時に必要となる寸法である。   On the other hand, the thickness W1 dimension of the convex part 22 is made about 15 mm. This thickness dimension of 15 mm is a dimension required at the time of integral molding of the door inner plate in order to suppress the movement of gas in the gap 24 described above.

次に図４，図５，図６をもって、凸部２２に設けた薄肉形状に付いて説明する。   Next, the thin shape provided on the convex portion 22 will be described with reference to FIGS.

図６において、線ａは試験前の従来の冷蔵庫であって、扉内板凸部と内箱側壁との間の寸法を示している。   In FIG. 6, line a is a conventional refrigerator before the test, and shows the dimension between the door inner plate projection and the inner box side wall.

尚、従来の冷蔵庫においては、側壁間寸法を９mmとし、冷蔵室扉の高さ寸法を８００mmとしていた。   In the conventional refrigerator, the dimension between the side walls is 9 mm, and the height of the refrigerator compartment door is 800 mm.

冷蔵庫の庫内側（冷蔵室，冷凍室，野菜室等）及び冷蔵室扉側（扉収納容器）には、実使用状態を想定して、負荷（ビ−ル瓶，缶詰，ペットボトル等）を入れ、冷蔵庫本体を固定し冷蔵室扉をＪＩＳ Ｃ ９８０１の１１.１.１の方法で１０〜２０万回、扉を開閉する試験を行った。   Loads (beer bottles, cans, PET bottles, etc.) are assumed on the inside of the refrigerator (refrigeration room, freezer room, vegetable room, etc.) and the refrigerator side door side (door storage container) assuming actual use conditions. The refrigerator main body was fixed, and the refrigerator door was tested for opening and closing the door 100 to 200,000 times by the method of 11.1.1 of JIS C 9801.

この結果、試験前は水平に取付けられていた冷蔵室扉は、線ａの状態より線ｂの状態に変位した。即ち、冷蔵室扉は４mm下がり（図７参照）、傾き角度で言うと０.３８度傾いた。この変位の原因は、ヒンジピン受けの磨耗、及び扉の変形等によるものである。   As a result, the refrigerator door that was installed horizontally before the test was displaced from the state of line a to the state of line b. That is, the refrigerator compartment door was lowered by 4 mm (see FIG. 7), and tilted by 0.38 degrees in terms of tilt angle. The cause of this displacement is due to wear of the hinge pin receiver, deformation of the door, and the like.

また、扉内板凸部と内箱側壁との間の寸法は、５.５mm縮小して、９.０mmが３.５mmとなっている（図６参照）。この３.５mmの寸法は、冷蔵室扉の開閉をスムーズに行う上で最低限確保しなければならない寸法である。すなわち、設計許容寸法の最小値となる。換言すると、冷蔵室扉５が４.０mm下がると、扉内板凸部と内箱側壁との間の寸法は５.５mm縮小する。   Further, the dimension between the door inner plate convex portion and the inner box side wall is reduced by 5.5 mm, and 9.0 mm is 3.5 mm (see FIG. 6). The dimension of 3.5 mm is a dimension that must be secured at least for smooth opening and closing of the refrigerator compartment door. That is, the design allowable dimension is the minimum value. In other words, when the refrigerator compartment door 5 is lowered by 4.0 mm, the dimension between the door inner plate convex portion and the inner box side wall is reduced by 5.5 mm.

そこで本実施例では、図４及び図５に示すように、扉下がりにより、凸部２２が内箱側壁に接近する側の凸部２２を薄肉形状２３としている。すなわち、凸部２２の上方は斜線部を除いた形状（傾斜面）とする。ここで、傾斜面は、凸部２２のＨ寸法（約８００mm）の約１／２〜１／３に当たる点Ｐ１（Ｈ１寸法約３００〜４００mm）と凸部２２の厚み寸法Ｗ１（Ｗ１寸法１５mm）の１／２〜２／３に当たる点Ｐ２（Ｗ２で３.０〜７.０mm）を結んで形成する。例えば、Ｗ１寸法を１５mmとした場合、Ｗ２寸法は３.０〜５.０mmとして、凸部を薄肉形状にする。   Therefore, in this embodiment, as shown in FIGS. 4 and 5, the convex portion 22 on the side where the convex portion 22 approaches the side wall of the inner box is formed into a thin shape 23 by lowering the door. That is, the upper part of the convex portion 22 has a shape (inclined surface) excluding the shaded portion. Here, the inclined surface has a point P1 (H1 size of about 300 to 400 mm) corresponding to about 1/2 to 1/3 of the H size (about 800 mm) of the convex portion 22 and a thickness dimension W1 of the convex portion 22 (W1 size of 15 mm). A point P2 (3.0 to 7.0 mm in W2) corresponding to 1/2 to 2/3 is formed. For example, when the W1 dimension is set to 15 mm, the W2 dimension is set to 3.0 to 5.0 mm, and the convex portion is made thin.

ここで、点Ｐ１について、図６にてさらに説明する。図６において、従来の冷蔵室扉は線ｂのように、０.３８度傾き、４.０mm下がる。この４.０mmは、凸部２２の高さを８００mmとした場合、凸部２２の先端部では約５.５mm、扉内板凸部と内箱側壁との間の寸法を縮小する方向に変位することを意味する。   Here, the point P1 will be further described with reference to FIG. In FIG. 6, the conventional refrigerator door tilts by 0.38 degrees as shown by line b and falls by 4.0 mm. This 4.0 mm is about 5.5 mm at the tip of the protrusion 22 when the height of the protrusion 22 is 800 mm, and is displaced in a direction to reduce the dimension between the door inner plate protrusion and the inner box side wall. It means to do.

このことより、従来の冷蔵室扉は、水平時（試験前）の扉内板凸部と内箱側壁との間の寸法は９.０mmに設定する必要があった。   From this, the conventional refrigerator compartment door needed to set the dimension between the door inner plate convex part and the inner box side wall to 9.0 mm when horizontal (before the test).

従って、凸部２２と内箱側壁との間の寸法を縮めることで、省エネルギー効果を向上させると共に、扉収納容器２０の大きさを拡大させることができる。そのために、従来の扉内板凸部と内箱側壁との間の寸法を、例えば９.０mmから６.０mmとして、凸部２２を上方に行くに従って薄くなる線ｃ（図６）のように予め設定する。すなわち、凸部２２と内箱側壁との間の寸法が下方よりも上方が大きくなるように薄くしておく。   Therefore, by reducing the dimension between the convex portion 22 and the inner box side wall, the energy saving effect can be improved and the size of the door storage container 20 can be increased. Therefore, the dimension between the conventional door inner plate convex portion and the inner box side wall is set to, for example, 9.0 mm to 6.0 mm, and the convex portion 22 becomes thinner as it goes upward as shown by line c (FIG. 6). Set in advance. That is, the dimension between the convex part 22 and the inner box side wall is made thin so that the upper part is larger than the lower part.

また、点Ｐ１は、この線ｃと先の６.０mm寸法線との交点である。本実施例においては、点Ｐ１を凸部２２のＨ寸法（図４）の約１／２〜１／３に当たる点としたものである。   Point P1 is the intersection of this line c and the previous 6.0 mm dimension line. In this embodiment, the point P1 corresponds to about 1/2 to 1/3 of the H dimension (FIG. 4) of the convex portion 22.

上記のように、凸部２２と内箱１６側壁との間の寸法を６.０mmとした線ｃの形状の冷蔵室扉５では、扉開閉試験後、線ｄのように変位する。換言すると、扉開閉試験前は線ｃのように、点Ｐ１までは隙間２４（スロート寸法）が従来の９.０mmから６.０mmとなって３.０mm縮まる。点Ｐ１から点Ｐ２までは隙間２４が６.０〜９.０mmの傾斜となって約１.５mm縮まる。   As described above, in the refrigerator compartment door 5 having the shape of the line c in which the dimension between the convex portion 22 and the side wall of the inner box 16 is 6.0 mm, it is displaced as the line d after the door open / close test. In other words, before the door opening / closing test, as shown by the line c, the gap 24 (throat dimension) is reduced to 3.0 mm from the conventional 9.0 mm until the point P1 by 3.0 mm. From the point P1 to the point P2, the gap 24 has an inclination of 6.0 to 9.0 mm and is reduced by about 1.5 mm.

また、扉開閉試験後においては、点Ｐ１（ａ）までが６.０mmから３.５mmとなることより、約１.７５mm縮まる。点Ｐ１（ａ）から上方では、３.５mmとなる。   In addition, after the door open / close test, the point P1 (a) is reduced from about 6.0 mm to 3.5 mm, so that it is reduced by about 1.75 mm. Above the point P1 (a), the distance is 3.5 mm.

尚、これは試験前と後の状態であるが、実使用状態では、試験前の状態から徐々に試験後の状態に向かって変位して行くので、省エネルギー効果は十分に得られるものである。   Although this is the state before and after the test, in the actual use state, the state is gradually displaced from the state before the test toward the state after the test, so that a sufficient energy saving effect can be obtained.

上記のように凸部２２を構成することにより、点Ｐ１（３３０mm）までの隙間２４は、従来よりも大幅に縮小され、点Ｐ１より上方の３３０〜８００mmの点Ｐ２までの隙間２４は６.０mm〜９.０mmと傾斜に沿って変位する。このことより、凸部２２と内箱１６側壁との間の寸法は、設計許容寸法の最小値である３.５mmを確保できるものである。   By constructing the convex portion 22 as described above, the gap 24 to the point P1 (330 mm) is greatly reduced as compared with the conventional case, and the gap 24 to the point P2 of 330 to 800 mm above the point P1 is 6. It is displaced along the slope from 0mm to 9.0mm. As a result, the dimension between the convex portion 22 and the side wall of the inner box 16 can ensure 3.5 mm, which is the minimum design allowable dimension.

また、上記説明においては隙間２４を６.０mmとして説明してきたが、例えば７.０mmとした場合、線ｃは線ｃ（ｂ）、線ｄは線ｄ（ｂ）のようになり、点３は点３（ａ）、点Ｐ２は点Ｐ２（ｂ）のようになる。従って、この時の隙間２４は３.５mmでなく、多少余裕を持った４.７mmとなる。また、凸部２２の寸法Ｗ２も、先に説明した３.０〜５.０mm小さくてすむものである。   In the above description, the gap 24 has been described as 6.0 mm. However, for example, when the gap 24 is 7.0 mm, the line c becomes the line c (b), the line d becomes the line d (b), and the point 3 Is point 3 (a), and point P2 is as point P2 (b). Therefore, the gap 24 at this time is not 3.5 mm, but is 4.7 mm with some margin. Further, the dimension W2 of the convex portion 22 can be reduced by 3.0 to 5.0 mm as described above.

一方、隙間２４を５.５mmとした場合には、隙間２４が３.５mmより小さくなってしまうため、扉のスムーズな開閉ができないおそれがある。   On the other hand, when the gap 24 is set to 5.5 mm, the gap 24 becomes smaller than 3.5 mm, so that there is a possibility that the door cannot be smoothly opened and closed.

また、上記説明においては、冷蔵室扉５が単一のもので説明したが、左右に２つ備えた両開き式（観音開き式）の扉に適用することもできるものである。   In the above description, the refrigerator compartment door 5 is described as a single one, but it can also be applied to a double-open (double door) door provided on the left and right.

以上説明した如き構成を有するものであるから、次の効果が得られるものである。   Since it has the configuration as described above, the following effects can be obtained.

即ち、開口を有する貯蔵室を備えた冷蔵庫本体と、該冷蔵庫本体の開口を開閉する扉と、該扉の前記貯蔵室側の左右両側の上下方向に設けた凸部と、を有する冷蔵庫において、前記凸部は、該凸部と前記貯蔵室の側壁との間の距離が下方よりも上方で大きくなるように設け、扉下がりにより変位した状態で前記凸部が前記貯蔵室の側壁に接触しないようにした。   That is, in a refrigerator having a refrigerator body with an opening, a door for opening and closing the opening of the refrigerator body, and convex portions provided on the left and right sides of the door on the side of the storage room, The convex portion is provided so that a distance between the convex portion and the side wall of the storage chamber is larger above the lower side, and the convex portion does not contact the side wall of the storage chamber when displaced by a door lowering. I did it.

これにより、ヒンジ等をもって回動自在に取付ける冷蔵室扉の隙間（スロート寸法）を縮めることができ、省エネルギー効果が図れると共に、長期間、扉開閉がスムーズに行うことができる、さらに、凸部２２が薄く設定されるので、扉収納容器２０の拡大を図ることができる。   Thereby, the clearance (throat dimension) of the refrigerator compartment door that can be pivotally attached with a hinge or the like can be reduced, an energy saving effect can be achieved, and the door can be smoothly opened and closed for a long period of time. Therefore, the door storage container 20 can be enlarged.

また、前記凸部の上方から下方まで傾斜面を有する。これにより、使用者には違和感を与えることなく、また、冷蔵庫側においては、長期使用に伴い冷蔵室扉が多少傾いても、使用者に違和感を与えることなく、スムーズな開閉動作ができる。   Moreover, it has an inclined surface from the upper direction of the said convex part to the downward direction. As a result, a smooth opening / closing operation can be performed without giving the user a sense of incongruity, and on the refrigerator side, even if the refrigerator compartment door is slightly inclined with long-term use, the user has no sense of discomfort.

また、前記凸部の前記傾斜面の始点は前記扉の下端から前記凸部の高さの１／２〜１／３付近とした。これにより、冷蔵室扉のスロート寸法を縮めて、省エネルギー効果が図れる。   Further, the starting point of the inclined surface of the convex portion is set to be about 1/2 to １ ／ of the height of the convex portion from the lower end of the door. Thereby, the throat dimension of a refrigerator compartment door can be shrunk and an energy saving effect can be aimed at.
