Description

本発明は、貯蔵ケース、貯蔵ケースの製造方法及び冷蔵庫に関する。   The present invention relates to a storage case, a method for manufacturing the storage case, and a refrigerator.

従来、家庭用の冷凍冷蔵庫には、食品を区分け収納するための樹脂成形品の貯蔵ケースが設置されている。射出成形によって成形された貯蔵ケースは、側壁が型の抜き勾配分だけ傾斜している。従って、冷蔵庫の正面から貯蔵ケースをみた場合は台形形状となり、高さが大きい深物ケースの場合などは、上端面開放面幅に対して底面幅が著しく小さくなり、意匠的に劣る。また、貯蔵ケースを縦方向に複数個配置した場合は、貯蔵ケースの側壁稜線に段差すなわち位置ずれが生じ、見栄えもよくない。
従って、貯蔵ケースの正面に別部品の化粧カバーを取り付け、貯蔵ケース全体を２部品によって構成する場合もあったが、樹脂使用量が増大し、また組立て工程も増大してしまう。
このため、貯蔵ケースの正面壁のみ幅を広げて対応する場合もあった（例えば、特許文献１参照）。 2. Description of the Related Art Conventionally, storage refrigerators for resin molded products for sorting and storing foods are installed in household refrigerator-freezers. The storage case molded by injection molding has a side wall inclined by the draft angle of the mold. Therefore, when the storage case is viewed from the front of the refrigerator, it becomes a trapezoidal shape, and in the case of a deep case with a large height, the bottom surface width is remarkably reduced with respect to the upper end surface opening surface width, which is inferior in design. In addition, when a plurality of storage cases are arranged in the vertical direction, a step, that is, a displacement occurs in the side wall ridge line of the storage case, and the appearance is not good.
Therefore, there is a case where a separate decorative cover is attached to the front of the storage case and the entire storage case is constituted by two parts. However, the amount of resin used increases and the assembly process also increases.
For this reason, only the front wall of the storage case may be handled with a wider width (for example, see Patent Document 1).

特開２００２−２３４０４５（第１頁、図７）JP 2002-234045 (first page, FIG. 7)

従来の一般的に実施されている技術によれば、貯蔵ケースのケース正面壁のみ幅を広げる手法なども用いられているが、透明樹脂材にて貯蔵ケースを成形した場合など、ケース正面壁とケース側壁、および、ケース正面壁とケース側壁外側に設けられるケース側レールとの接合稜線がケース正面壁に透過して見えてしまい、意匠的に好ましくないといった問題があった。   According to the conventional commonly practiced technique, a method of increasing the width of only the case front wall of the storage case is also used, but when the storage case is formed of a transparent resin material, There was a problem that the case side wall and the connecting ridge line between the case front wall and the case side rail provided on the outer side of the case side are seen through the case front wall, which is undesirable in design.

本発明は、上記のような課題を解決するためになされたもので、意匠性の高い貯蔵ケース、貯蔵ケースの製造方法及び冷蔵庫を安価に提供することを目的とする。   The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a storage case with high designability, a method for manufacturing the storage case, and a refrigerator at low cost.

本発明に係る貯蔵ケースは、一体に樹脂成形された上面開放型の貯蔵ケースであって、側壁の正面壁近傍を拡幅して側壁部を底板に対して立設すると共に、立設した側壁に連続する正面壁をほぼ正方形状若しくは長方形状に形成したものである。   The storage case according to the present invention is an open top storage case integrally molded with resin, and widens the vicinity of the front wall of the side wall so that the side wall portion stands up against the bottom plate, and the side wall is erected. A continuous front wall is formed in a substantially square or rectangular shape.

本発明によれば、意匠性にすぐれた貯蔵ケースを安価に提供することができる。
また、本発明によれば、金型製作費が低減し、成型費用及び樹脂使用量を低減することができる。 ADVANTAGE OF THE INVENTION According to this invention, the storage case excellent in the design property can be provided at low cost.
Further, according to the present invention, the mold production cost can be reduced, and the molding cost and the amount of resin used can be reduced.

図１に示すように、冷蔵庫本体１の貯蔵室にはハンドル１１を備えた貯蔵ケース１０が収められている。そしてこの貯蔵ケース１０は、図２に示すように、開閉自在の扉２を設けた冷蔵庫本体１の貯蔵室に、複数個、縦方向に並列して設置されている。貯蔵ケース１０に設けたハンドル１１は貯蔵ケース１０を前後に移動させるためのもので、貯蔵ケース１０の正面壁１２の上端に、下端開放の形状にて一体成形して設けられている。
図１に示すように、貯蔵ケース１０の側壁１３の外側には凸形状のケースレール１４が設けられ、冷蔵庫本体１の内壁側部に設けられた本体レール１ａの凹状溝に挿入され、これによって貯蔵ケース１を冷蔵庫本体１ａ内に保持して冷蔵庫の前後に摺動させるようにしてある。 Embodiment 1 FIG.
1 is a perspective view of a storage case according to Embodiment 1 of the present invention, FIG. 2 is a front view of a refrigerator including the storage case of FIG. 1, FIG. 3 is a top view of the storage case of FIG. 3 is a cross-sectional view taken along the line AA in FIG. 3, FIG. 6 is a cross-sectional view taken along the line BB in FIG. 3, and FIG. 7 is a cross-sectional view taken along the line CC in FIG.
As shown in FIG. 1, a storage case 10 having a handle 11 is stored in a storage chamber of the refrigerator body 1. As shown in FIG. 2, a plurality of storage cases 10 are installed in parallel in the vertical direction in a storage chamber of the refrigerator main body 1 provided with a door 2 that can be freely opened and closed. A handle 11 provided in the storage case 10 is for moving the storage case 10 back and forth, and is integrally formed on the upper end of the front wall 12 of the storage case 10 in an open shape.
As shown in FIG. 1, a convex case rail 14 is provided outside the side wall 13 of the storage case 10 and is inserted into a concave groove of the main body rail 1 a provided on the inner wall side portion of the refrigerator main body 1. The storage case 1 is held in the refrigerator body 1a and is slid back and forth in the refrigerator.

図３〜図７に示すように、貯蔵ケース１０は、ほぼ正方形状若しくは長方形状をなす正面壁１２、左右の側壁１３、背面壁１５及び底板１６によって構成された上端面開放形の樹脂射出形成による一体樹脂成形品で、側壁１３及び背面壁１５は底板１６に対して成形型の抜き勾配分だけ外側に傾斜しているが、正面壁１２は底板１６に対してほぼ直角に形成されている。そして、底板１６はその正面壁１２の近傍が正面壁１２と同一幅となる幅広範囲１７を有しており、側壁１３の正面壁１２の近傍の一部が底板１６に対してほぼ垂直をなして拡幅する立設壁１３ａを備え、この立設壁１３ａを介して側壁３と正面壁１２が接続している。このため、貯蔵ケース１０を正面よりみると、幅Ｘと深さＨ（高さ）が異なる場合は長方形状、幅Ｘと深さＨが等しい場合は正方形状となる。なお、幅広範囲１７の奥行き方向の幅は、清掃性を考慮し、成人の平均的指の大きさより１０ｍｍ以上広いことが望ましい。   As shown in FIGS. 3 to 7, the storage case 10 has a resin injection molding with an open top surface formed by a front wall 12, left and right side walls 13, a back wall 15, and a bottom plate 16 having a substantially square or rectangular shape. The side wall 13 and the back wall 15 are inclined outwardly by the draft of the mold with respect to the bottom plate 16, but the front wall 12 is formed substantially at right angles to the bottom plate 16. . The bottom plate 16 has a wide range 17 in which the vicinity of the front wall 12 is the same width as the front wall 12, and a part of the side wall 13 near the front wall 12 is substantially perpendicular to the bottom plate 16. The side wall 3 and the front wall 12 are connected via the standing wall 13a. For this reason, when the storage case 10 is viewed from the front, it becomes a rectangular shape when the width X and the depth H (height) are different, and becomes a square shape when the width X and the depth H are equal. The width in the depth direction of the wide range 17 is desirably 10 mm or more wider than the average finger size of an adult in consideration of cleaning properties.

こうして、貯蔵ケース１０に透明樹脂材を用いた場合でも、正面壁１２と側壁１３、および正面壁１２と側壁１３のケース側レール１４との接合稜線が透過して見えることもなく、また、ケース側レール１４の幅寸法Ｚは、貯蔵ケース１０の正面壁１２の幅寸法Ｘより小さく、このためケース側レール１４は正面壁１２に隠れてケース正面からは見えない。そして、冷蔵庫１の貯蔵室は、正面から見て貯蔵ケース１０の側壁１３が立設壁１３ａを有するため垂直であり、直線的な稜線を実現できるため、意匠性に優れることになる。こうして貯蔵ケース１０の美観が損なわれず、操作性、収納整理性にも優れ、ユーザーメリットも向上する。また、貯蔵ケース１０にハンドル１１を設けたため、貯蔵ケース１０を冷蔵庫１下方の貯蔵室に配置した場合などは貯蔵ケース１０の操作性に優れ、意匠性、使い勝手がよく、そのうえ安価である。   Thus, even when a transparent resin material is used for the storage case 10, the front ridge 12 and the side wall 13 and the joining ridge line between the front wall 12 and the case side rail 14 of the side wall 13 do not appear to be transparent. The width dimension Z of the side rail 14 is smaller than the width dimension X of the front wall 12 of the storage case 10, so that the case side rail 14 is hidden by the front wall 12 and cannot be seen from the front of the case. And the storage room of the refrigerator 1 is vertical because the side wall 13 of the storage case 10 has the standing wall 13a when viewed from the front, and can realize a straight ridge line, and therefore has excellent design. Thus, the aesthetic appearance of the storage case 10 is not impaired, the operability and the storage organization are excellent, and the user merit is improved. In addition, since the handle 11 is provided in the storage case 10, when the storage case 10 is disposed in the storage room below the refrigerator 1, the operability of the storage case 10 is excellent, the design is easy to use, and the cost is low.

上記の貯蔵ケース１０を射出成形するには、図１０（図８のＤ−Ｄ断面図）、図１１（図９のＥ−Ｅ断面図）に示すように、射出成型用金型である雌成形型３０及び雄成形型４０等を用いてキャビテイ内に加熱溶融した樹脂を充填し、これを冷却固化させて貯蔵ケース１０を成形する。この際、幅広範囲１７近傍の側壁１３は、成形時において雄型のスライド駒４１と雌型のスライド駒３１を用いて成形する。すなわち、立設壁１３ａの内壁及びこれに続く正面壁１２の左右端近傍の内壁においては、雄型のスライド駒４１を用いて内面壁を成形し、また、立設壁１３ａの外壁近傍においては、雌型のスライド駒３１を用いて外面壁を成形する。   In order to injection mold the storage case 10, as shown in FIG. 10 (DD sectional view of FIG. 8) and FIG. 11 (EE sectional view of FIG. 9), a female which is an injection mold. The mold 30 and the male mold 40 are used to fill the cavity with resin melted by heating, and this is cooled and solidified to mold the storage case 10. At this time, the side wall 13 in the vicinity of the wide range 17 is formed by using the male slide piece 41 and the female slide piece 31 at the time of forming. That is, on the inner wall of the standing wall 13a and the inner wall in the vicinity of the right and left ends of the front wall 12 following this, an inner wall is formed using the male slide piece 41, and in the vicinity of the outer wall of the standing wall 13a. The outer surface wall is formed using the female slide piece 31.

貯蔵ケース１０の正面壁１２は底板１６に対して垂直（図７において９０度）となっているが、このように正面壁１２を垂直とすることで貯蔵ケース１０の正面投影形状の垂直度が増し、より意匠性に優れた貯蔵ケース１０を得ることができる。この垂直な正面壁１２を形成するために、例えば図１３（図１２のＦ−Ｆ断面図）に示すように、射出成形用金型を全体に５度以上傾斜して形成すると、正面壁１２を成形するためにスライド駒を用いることなく実現可能となり、射出成形用金型の制作費を低減することができ、また、成型費用、樹脂使用量を低減することができる。   Although the front wall 12 of the storage case 10 is perpendicular to the bottom plate 16 (90 degrees in FIG. 7), the perpendicularity of the front projection shape of the storage case 10 is increased by making the front wall 12 vertical in this way. As a result, the storage case 10 having a more excellent design can be obtained. In order to form the vertical front wall 12, for example, as shown in FIG. 13 (FF sectional view of FIG. 12), when the injection mold is inclined at an angle of 5 degrees or more as a whole, the front wall 12 is formed. This can be realized without using a slide piece in order to mold the mold, so that the production cost of the injection mold can be reduced, and the molding cost and the amount of resin used can be reduced.

その際、背面壁１５も、金型の抜き方向に対し、アンダーカットにならない方向に、抜き勾配分だけ傾斜（図１３に示すように、底板１６と背面壁１５とは９８度以上の角度をなし、背面壁１５は抜き方向に対して３度以上傾斜）させている。なお、金型の抜き方向に対して、アンダーカットにならない方向に３度以上の勾配があれば支障なく離型が可能であり、このため傾斜角度は５度の例を示したが、これに限定されるものではなく、３度以上であればよい。このように成形型構造として３度以上全体に傾斜させたものであり、このため正面壁１２成形のためのスライド駒が不要であり、金型制作費を低減することができる。   At that time, the back wall 15 is also inclined by a draft angle in a direction not undercutting with respect to the mold drawing direction (as shown in FIG. 13, the bottom plate 16 and the back wall 15 have an angle of 98 degrees or more. None, the back wall 15 is inclined at least 3 degrees with respect to the drawing direction. In addition, if there is a gradient of 3 degrees or more in the direction where the undercut does not occur with respect to the mold drawing direction, it is possible to release the mold without any trouble. For this reason, the inclination angle is 5 degrees. It is not limited and may be 3 degrees or more. As described above, the mold structure is inclined by 3 degrees or more as a whole, so that a slide piece for molding the front wall 12 is unnecessary, and the mold production cost can be reduced.

実施の形態２．
図１４は本発明の実施の形態２に係る冷蔵庫の貯蔵ケースの斜視図、図１５は図１４の側面図である。なお、実施の形態１と同一部分には同じ符号を付し、説明を省略する。図に示すように、雌型、雄型のスライド駒３１，４１によって成形された貯蔵ケース１０の前面壁１２近傍の側壁、例えば貯蔵ケース１０の立設壁１３ａの側面には貫通穴２０が形成されている。 Embodiment 2. FIG.
14 is a perspective view of a storage case for a refrigerator according to Embodiment 2 of the present invention, and FIG. 15 is a side view of FIG. The same parts as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted. As shown in the drawing, a through hole 20 is formed in a side wall in the vicinity of the front wall 12 of the storage case 10 formed by female and male slide pieces 31 and 41, for example, a side surface of the standing wall 13a of the storage case 10. Has been.

すなわち、立設壁１３ａの内壁から正面壁１２の左右端近傍の内壁にいたる壁面においては、雄型のスライド駒４１を用いて内面壁が成形され、また、立設壁１３ａの外壁近傍においては、雌型のスライド駒３１を用いて外面壁が成形されるが、成形時の樹脂圧力によって雄型のスライド駒４１が移動しないように、成形時に雌型のスライド駒３１から雄型のスライド駒４１に移動防止用の固定ピン２１を挿入して雄型のスライド駒４１を固定状態にする。よって、貯蔵ケース１０の立設壁１３ａに設けた貫通穴２０は、この固定ピン２１により形成されるものである。   That is, on the wall surface from the inner wall of the standing wall 13a to the inner wall near the left and right ends of the front wall 12, an inner wall is formed using the male slide piece 41, and in the vicinity of the outer wall of the standing wall 13a. The outer wall is formed using the female slide piece 31, but the male slide piece 31 is moved from the female slide piece 31 during molding so that the male slide piece 41 does not move due to the resin pressure at the time of molding. The movement-preventing fixing pin 21 is inserted into 41 so that the male slide piece 41 is fixed. Therefore, the through hole 20 provided in the standing wall 13 a of the storage case 10 is formed by the fixing pin 21.

このようにして、貯蔵ケース１０の成形時において、雄型のスライド駒４１を固定ピン２１によって固定することにより成形不良を減少させることができ、これによって樹脂使用量及び加工費を低減することができる。また、貫通穴２０を幅広範囲１７の側壁１３に設けた場合は、正面から貫通穴２０は見えず、貯蔵ケース１０の美観を損ねることはない。
その他の構成、作用、効果は、実施の形態１に示した場合と実質的に同様なので説明を省略する。 In this way, when the storage case 10 is molded, it is possible to reduce molding defects by fixing the male slide piece 41 with the fixing pin 21, thereby reducing the amount of resin used and the processing cost. it can. Moreover, when the through hole 20 is provided in the side wall 13 of the wide range 17, the through hole 20 cannot be seen from the front, and the aesthetic appearance of the storage case 10 is not impaired.
Other configurations, operations, and effects are substantially the same as in the case of the first embodiment, and thus description thereof is omitted.
