Description

本発明は、貯蔵室内に食品等を冷却保存する冷蔵庫に関し、特に、貯蔵室を開閉自在に塞ぐ断熱扉に設けられた凹みハンドル部を有する冷蔵庫に関する。   The present invention relates to a refrigerator that cools and stores food or the like in a storage chamber, and more particularly, to a refrigerator that has a recessed handle portion provided in a heat insulating door that closes the storage chamber in an openable and closable manner.

従来の扉の前面に把手が設けられた冷蔵庫として、以下の構造が知られている。図６では、冷蔵庫１００の外観斜視図を示し、冷蔵庫１００の本体１０１の前面には、本体１０１上側の冷蔵室を開閉自在に塞ぐ冷蔵室扉１０２及び本体１０１下側の冷凍室を開閉自在に塞ぐ冷凍室扉１０３が配設されている。そして、冷蔵室扉１０２及び冷凍室扉１０３には、本体１０１の上下方向に渡り、それぞれの扉１０２、１０３を開閉するためのハンドル部１０４、１０５が取り付けられている。   The following structure is known as a refrigerator having a handle provided on the front surface of a conventional door. FIG. 6 shows an external perspective view of the refrigerator 100. A refrigerator door 102 for closing the refrigerator compartment above the main body 101 and a freezer compartment below the main body 101 can be opened and closed on the front surface of the main body 101 of the refrigerator 100. A freezer compartment door 103 for closing is disposed. Handle portions 104 and 105 for opening and closing the doors 102 and 103 are attached to the refrigerator compartment door 102 and the freezer compartment door 103 in the vertical direction of the main body 101.

ハンドル部１０４、１０５は、例えば、中空パイプ形状のアルミニウム製の把手である。そして、ハンドル部１０４、１０５は、円柱形状に加工されることで、使用者が握り易い形状となっている。尚、ハンドル部１０４、１０５は、それぞれネジ等の取り付け部材を介して冷蔵室扉１０２及び冷凍室扉１０３に取り付けられている（例えば、特許文献１参照。）。   The handle portions 104 and 105 are, for example, hollow pipe-shaped aluminum handles. And the handle | steering-wheel parts 104 and 105 are the shapes where a user is easy to grip by being processed into a column shape. The handle portions 104 and 105 are respectively attached to the refrigerator compartment door 102 and the freezer compartment door 103 via attachment members such as screws (see, for example, Patent Document 1).

特許第５８６８２４５号公報Japanese Patent No. 5868245

上述した冷蔵室扉１０２は、主に、意匠面となる鋼板製パネル板と、その鋼板製パネル板に庫内側から組み付けられる合成樹脂製内板と、その鋼板製パネル板と合成樹脂製内板の間の内部空間に充填される断熱発泡剤とにより構成されている。そして、ハンドル部１０４の構造において、例えば、デザイン性の観点から、現状の把手構造から凹みハンドル構造に変更する場合がある。   The above-described refrigerator compartment door 102 is mainly composed of a steel plate panel serving as a design surface, a synthetic resin inner plate assembled to the steel plate panel from the inside of the cabinet, and the steel plate panel and the synthetic resin inner plate. It is comprised with the heat insulation foaming agent with which the interior space of this is filled. And in the structure of the handle | steering-wheel part 104, from a viewpoint of design property, it may change from the present handle structure to a dent handle structure, for example.

この場合、ただ単に、冷蔵室扉１０２の所望の領域に凹みハンドル部を配置させる対応では、その凹みハンドル部の配置により、鋼板製パネル板と合成樹脂製内板との間の内部空間が狭くなり、十分な断熱発泡剤の厚みが確保出来なくなってしまう。その結果、凹みハンドル部内の上記断熱発泡剤の厚みが十分でない領域に結露が発生するという問題がある。   In this case, simply by arranging the concave handle portion in a desired region of the refrigerator compartment door 102, the inner space between the steel plate panel and the synthetic resin inner plate is narrowed by the arrangement of the concave handle portion. Therefore, it becomes impossible to secure a sufficient thickness of the heat insulating foaming agent. As a result, there is a problem that dew condensation occurs in a region where the thickness of the heat insulating foaming agent in the recessed handle portion is not sufficient.

また、上記結露の問題を解決する方法として、凹みハンドル部の配置領域でも十分な断熱発泡剤の厚みが確保できるように、新たな成形金型を作製することが考えられる。しかしながら、新たな成形金型を作製することで、従前の成形金型が使用出来なくなり、成形金型の投資費用が大幅に増大するという問題がある。更には、製品設計もやり直す必要があり、それに伴うコストアップだけでなく、納期の遅れ等も発生するという問題がある。   Further, as a method for solving the above-mentioned dew condensation problem, it is conceivable to prepare a new molding die so that a sufficient thickness of the heat insulating foaming agent can be secured even in the region where the dent handle portion is arranged. However, by producing a new molding die, there is a problem that the conventional molding die cannot be used and the investment cost of the molding die is greatly increased. Furthermore, there is a problem that it is necessary to redo the product design, resulting in not only a cost increase but also a delay in delivery.

更には、凹みハンドル部の配置領域に十分な断熱発泡剤の厚みを確保するため、合成樹脂製内板を庫内側へと突出させることが考えられる。しかしながら、冷蔵室扉１０２の庫内側には、複数のドアポケットが配設されるため、その収納スペースが低減され、使用者の利便性が損なわれるという問題がある。   Furthermore, in order to ensure a sufficient thickness of the heat insulating foaming agent in the region where the concave handle portion is disposed, it is conceivable that the synthetic resin inner plate protrudes toward the inside of the cabinet. However, since a plurality of door pockets are disposed inside the refrigerator compartment door 102, there is a problem that the storage space is reduced and the convenience of the user is impaired.

本発明は、上記の事情に鑑みてなされたものであり、その目的とするところは、貯蔵室を開閉自在に塞ぐ断熱扉に凹みハンドル部を設け、結露を防止すると共に庫内側収納スペースが十分に確保される冷蔵庫を提供することにある。   The present invention has been made in view of the above circumstances, and the object of the present invention is to provide a recessed handle portion on a heat-insulating door that closes the storage chamber so that it can be opened and closed, thereby preventing condensation and providing sufficient storage space inside the warehouse. It is to provide a refrigerator secured.

本発明の冷蔵庫では、開口部が形成される断熱箱体と、前記断熱箱体に取り付けられ前記開口部を開閉自在に塞ぐ断熱扉と、を備え、前記断熱扉は、意匠面を形成する外面板材と、前記外面板材に内側から組み付けられる内面板材と、前記外面板材と前記内面板材との間の空間に充填される断熱材と、前記外面板材と前記内面板材との間に配設される凹みハンドル部と、有し、前記内面板材には、少なくとも前記外面板材と平行に配置される第１の平坦面と、前記外面板材に対して離れる方向に傾斜する第２の平坦面とが形成され、前記第２の平坦面は前記凹みハンドル部の長手方向に沿って配置されていることを特徴とする。   The refrigerator of the present invention includes a heat insulating box in which an opening is formed, and a heat insulating door that is attached to the heat insulating box and covers the opening so as to be openable and closable, and the heat insulating door is an outer surface that forms a design surface. A plate member, an inner plate member assembled to the outer plate member from the inside, a heat insulating material filled in a space between the outer plate member and the inner plate member, and disposed between the outer plate member and the inner plate member. The inner surface plate member has at least a first flat surface disposed in parallel with the outer surface plate member, and a second flat surface inclined in a direction away from the outer surface plate member. The second flat surface is arranged along the longitudinal direction of the recessed handle portion.

また、本発明の冷蔵庫では、前記凹みハンドル部は前記断熱扉の上方側面側に配設され、前記断熱扉が前記開口部を塞ぐ状態において、前記第２の平坦面は前記開口部側に向けて斜め上方に傾斜する面であり、前記第２の平坦面と前記第１の平坦面との成す角度は１３５度よりも大きいことを特徴とする。   In the refrigerator of the present invention, the recessed handle portion is disposed on an upper side surface side of the heat insulating door, and the second flat surface faces the opening portion side when the heat insulating door closes the opening portion. The angle between the second flat surface and the first flat surface is greater than 135 degrees.

また、本発明の冷蔵庫では、前記開口部側の前記断熱扉の前記内面板材には卵収納部が配設され、前記卵収納部は前記第２の平坦面の下方に配設されていることを特徴とする。   In the refrigerator of the present invention, an egg storage portion is disposed on the inner plate of the heat insulating door on the opening side, and the egg storage portion is disposed below the second flat surface. It is characterized by.

A second flat surface is inclined to the inner side of the inner surface plate material of the heat insulating door in the formation area of the recessed handle portion. With this structure, the thickness of the heat insulating material of the heat insulating door is sufficiently ensured in the formation region of the concave handle portion, and it is possible to prevent dew condensation from occurring in the concave handle portion. Furthermore, since the molding die for molding the inner surface plate material can be used by improving the conventional molding die, the cost increase is significantly reduced as compared with the case of newly manufacturing the molding die.

また、本発明の冷蔵庫では、内面板材に設けられた第２の平坦面と内面板材の大部分を構成する第１の平坦面との成す角度が１３５°よりも大きくなるように、第２の平坦面が成形されている。この構造により、凹みハンドル部の形成領域では、断熱扉の断熱材の厚みが十分に確保されると共に、断熱扉の庫内側のドアポケットの収納スペースが十分に確保されている。   In the refrigerator of the present invention, the second flat surface provided on the inner surface plate material and the first flat surface constituting most of the inner surface plate material have an angle greater than 135 °. A flat surface is molded. With this structure, the thickness of the heat insulating material of the heat insulating door is sufficiently secured in the formation region of the recessed handle portion, and the storage space of the door pocket inside the warehouse of the heat insulating door is sufficiently secured.

また、本発明の冷蔵庫では、凹みハンドル部が断熱扉の上方側面に沿って配設され、凹みハンドル部の形成領域では、断熱扉のドアポケットに卵収納部が配設されている。そして、第２の平坦面が出来る限り立ち上がった状態にて配設されることで、断熱扉のドアポケットの収納スペースが十分に確保されている。この構造により、使用者は、卵収納部への卵の出し入れ作業が容易となり、使用者の利便性が向上される。   Moreover, in the refrigerator of this invention, the dent handle part is arrange | positioned along the upper side surface of a heat insulation door, and the egg storage part is arrange | positioned in the door pocket of the heat insulation door in the formation area of the dent handle part. And the storage space of the door pocket of a heat insulation door is fully ensured by arrange | positioning in the state which stood up the 2nd flat surface as much as possible.

However, in FIG. 2, for convenience of explanation, most of the plurality of concave and convex shapes provided on the inner surface plate 32 are omitted.

図示したように、外面板材３１と内面板材３２とで囲まれる内部空間の上端及び下端は、例えば、合成樹脂製のキャップ部３４、３５で塞がれている。上記上端側を塞ぐキャップ部３４には凹みハンドル部５が一体に成形され、凹みハンドル部５は外面板材３１と内面板材３２との間の内部空間内に配設されている。そして、外面板材３１と内面板材３２との間の内部空間には、例えば、発泡ポリウレタン製の断熱材３８（図３参照）が充填発泡されている。   As illustrated, the upper end and the lower end of the internal space surrounded by the outer plate member 31 and the inner plate member 32 are closed with cap portions 34 and 35 made of synthetic resin, for example. A concave handle portion 5 is formed integrally with the cap portion 34 that closes the upper end side, and the concave handle portion 5 is disposed in an internal space between the outer plate member 31 and the inner plate member 32. In the internal space between the outer plate member 31 and the inner plate member 32, for example, a foamed polyurethane heat insulating material 38 (see FIG. 3) is filled and foamed.

上述したように、凹みハンドル部５は、キャップ部３４と一体成形されている。凹みハンドル部５は、使用者が断熱扉４を開閉する際に指を掛けるための部位であり、冷蔵庫１の上下方向に窪むように成形されている。尚、凹みハンドル部５はキャップ部３４と一体に成形される場合に限定されるものではなく、それぞれ別体として成形され組み付けられる場合でも良い。また、凹みハンドル部５の表面に種々の色から成る革製のカバー部（図示せず）が取り付けられ、意匠性が高められる場合でも良い。   As described above, the recessed handle portion 5 is integrally formed with the cap portion 34. The dent handle portion 5 is a portion for placing a finger when the user opens and closes the heat insulating door 4, and is shaped to be recessed in the vertical direction of the refrigerator 1. The recessed handle portion 5 is not limited to being formed integrally with the cap portion 34, and may be formed and assembled separately. Moreover, the case where the leather cover part (not shown) which consists of various colors is attached to the surface of the dent handle part 5, and the design property is improved may be sufficient.

図３は、図２に示す断熱扉４のＡ−Ａ線方向の断面図を示すが、説明の都合上、図２に示す断熱扉４が組み付けられた状態を示している。   FIG. 3 is a cross-sectional view of the heat insulating door 4 shown in FIG. 2 in the AA line direction. For convenience of explanation, FIG. 3 shows a state where the heat insulating door 4 shown in FIG. 2 is assembled.

図３では断熱扉４の凹みハンドル部５の形成領域の断面を示している。上述したように、断熱扉４の上側辺に沿って凹みハンドル部５が設けられている。凹みハンドル部５には、下方に窪む凹状部４１が形成されている。凹状部４１は、断熱扉４を開けようとする使用者が、その指先を充分に差し込める深さを有している。そして、凹状部４１が十分な深さを持って形成される一方、矢印４２にて示す領域では、断熱扉４の厚みが確保される必要がある。矢印４２にて示す領域では、断熱扉４の厚みが薄くなることで、断熱材３８の厚みが不足し、凹みハンドル部５に結露が発生してしまうからである。   In FIG. 3, the cross section of the formation area of the dent handle part 5 of the heat insulation door 4 is shown. As described above, the recessed handle portion 5 is provided along the upper side of the heat insulating door 4. The recessed handle portion 5 is formed with a recessed portion 41 that is recessed downward. The concave portion 41 has a depth that allows a user who wants to open the heat insulating door 4 to fully insert his fingertip. And while the recessed part 41 is formed with sufficient depth, in the area | region shown by the arrow 42, the thickness of the heat insulation door 4 needs to be ensured. This is because, in the region indicated by the arrow 42, the thickness of the heat insulating door 4 is reduced, so that the thickness of the heat insulating material 38 is insufficient, and condensation is generated in the recessed handle portion 5.

そこで、本実施形態では、丸印４３にて示す領域において、凹みハンドル部５の配置領域に沿って、内面板材３２に第２の平坦面３２Ｂが形成されている。上述したように、第２の平坦面３２Ｂは、断熱箱体２（図１（Ｂ）参照）の冷蔵室１２（図１（Ｂ）参照）側へと傾斜するように配設されている。そして、凹みハンドル部５は断熱扉４の幅方向の大部分に渡り形成されるが、第２の平坦面３２Ｂは凹みハンドル部５の配置領域に対応して形成されている。この構造により、凹みハンドル部５の配置領域において、断熱材３８の厚みが十分に確保され、凹みハンドル部５に結露が発生することが防止される。   Therefore, in the present embodiment, in the region indicated by the circle 43, the second flat surface 32 </ b> B is formed on the inner surface plate member 32 along the arrangement region of the recessed handle portion 5. As described above, the second flat surface 32B is disposed so as to be inclined toward the refrigerator compartment 12 (see FIG. 1B) side of the heat insulating box 2 (see FIG. 1B). And although the dent handle part 5 is formed over most of the width direction of the heat insulation door 4, the 2nd flat surface 32B is formed corresponding to the arrangement | positioning area | region of the dent handle part 5. FIG. With this structure, a sufficient thickness of the heat insulating material 38 is ensured in the arrangement region of the concave handle portion 5, and condensation is prevented from occurring in the concave handle portion 5.

ここで、丸印４３にて示す領域において、点線４４にて示すラインが、図６にて示す従来の把手型のハンドル部１０４の構造における内面板材の成形形状を示している。従来の構造では、本実施形態の凹みハンドル部５が冷蔵室扉１０２の上側側面に配設されてなく、冷蔵室扉１０２の鋼板製パネル板は上方まで配置されている。そのため、本実施形態の矢印４２にて示す領域に対応する冷蔵室扉１０２の厚みは十分に確保されており、結露の問題は全く発生していなかった。その結果、点線４４にて示すように、本実施形態の第２の平坦面３２Ｂが、冷蔵室扉１０２の合成樹脂製内板に配設されることなく、合成樹脂製内板も上方まで配置され端部は曲面形状として成形されている。   Here, in a region indicated by a circle 43, a line indicated by a dotted line 44 indicates a molded shape of the inner surface plate material in the structure of the handle portion 104 of the conventional handle shown in FIG. In the conventional structure, the recessed handle portion 5 of the present embodiment is not disposed on the upper side surface of the refrigerator compartment door 102, and the steel plate panel of the refrigerator compartment door 102 is disposed to the upper side. Therefore, the thickness of the refrigerator compartment door 102 corresponding to the region indicated by the arrow 42 in this embodiment is sufficiently secured, and no problem of dew condensation has occurred. As a result, as indicated by a dotted line 44, the second flat surface 32B of the present embodiment is not disposed on the synthetic resin inner plate of the refrigerator compartment door 102, and the synthetic resin inner plate is also disposed upward. The end portion is shaped as a curved surface.

つまり、本実施形態では、内面板材３２の第２の平坦面３２Ｂが庫内側へと傾斜して配設されることで、断熱扉４内の断熱材３８の必要な厚みが確保される。詳細は図５を用いて後述するが、第１の平坦面３２Ａと第２の平坦面３２Ｂとの成す角度αが、１３５°以上となるように、第２の平坦面３２Ｂは成形されている。この構造により、庫内側の収納スペース、特に、断熱扉４のドアポケットの収納スペースに与える影響を最小限に抑えることで、使用者の利便性を妨げることが防止される。更に、ドアポケットの収納スペースの配置変更も必要なく、下記成形金型の改造も容易となる。   That is, in the present embodiment, the necessary thickness of the heat insulating material 38 in the heat insulating door 4 is ensured by arranging the second flat surface 32B of the inner surface plate member 32 so as to be inclined toward the inside of the cabinet. Although details will be described later with reference to FIG. 5, the second flat surface 32B is formed so that the angle α formed by the first flat surface 32A and the second flat surface 32B is 135 ° or more. . With this structure, it is possible to prevent the convenience of the user from being hindered by minimizing the influence on the storage space inside the warehouse, particularly the storage space of the door pocket of the heat insulating door 4. Further, it is not necessary to change the arrangement of the storage space of the door pocket, and the following molding die can be easily modified.

更には、内面板材３２を形成する成形金型に関し、従前の成形金型に改良を加えることで、本実施形態の第２の平坦面３２Ｂを成形することができる。上述したように、丸印４３にて示す領域において、点線４４にて示すラインが、図６にて示す従来の冷蔵室扉１０２の合成樹脂製内板の成形形状である。そのため、成形金型では、点線４４にて示す凸形状部分を削る対応にて、第２の平坦面３２Ｂを成形可能な成形金型として用いることができる。つまり、従前の成形金型の一部を削る対応にて、本実施形態用の成形金型として用いることができ、成形金型の改造が容易であり、新たに成形金型を製造する場合と比較してコストアップを大幅に低減できる。   Furthermore, regarding the molding die for forming the inner surface plate 32, the second flat surface 32B of the present embodiment can be molded by improving the conventional molding die. As described above, in the region indicated by the circle 43, the line indicated by the dotted line 44 is the molded shape of the synthetic resin inner plate of the conventional refrigerator compartment door 102 shown in FIG. Therefore, in the molding die, the second flat surface 32B can be used as a molding die that can be molded in response to cutting the convex portion indicated by the dotted line 44. In other words, it can be used as a molding die for this embodiment in response to scraping a part of a conventional molding die, and it is easy to remodel the molding die, and a new molding die is manufactured. Compared with this, the cost increase can be greatly reduced.

また、新たに成形金型を製造する必要がなく、製品設計を一からやり直す必要がなくなり、そのやり直しに伴うコストアップが防止され、納期の遅れに伴う受注機会の喪失や発注のキャンセル等も防止される。   In addition, there is no need to manufacture a new mold, it is no longer necessary to start over from the beginning of the product design, cost increases associated with the restart, and loss of order receipts due to delays in delivery and cancellation of orders are prevented. Is done.

図４は、本発明の実施形態に係る冷蔵庫１の断熱扉４の庫内側から見た構造を説明する斜視図である。図５は、図４に示す断熱扉４のＢ−Ｂ線方向の断面図である。   Drawing 4 is a perspective view explaining the structure seen from the warehouse inside of heat insulation door 4 of refrigerator 1 concerning an embodiment of the present invention. FIG. 5 is a cross-sectional view of the heat insulating door 4 shown in FIG. 4 in the BB line direction.

図４に示すように、断熱扉４の庫内側の面には、ガスケット３３が、その最外周に略矩形の枠状に取り付けられている。ガスケット３３は、断熱箱体２（図１（Ｂ）参照）の冷蔵室１２（図１（Ｂ）参照）の周縁部の前面と断熱扉４との間をシールしている。この構造により、外部から冷蔵庫１の庫内への熱の侵入を抑えると共に、庫内の冷気が外部へと逃げることを抑えている。   As shown in FIG. 4, a gasket 33 is attached to the outermost surface of the heat insulating door 4 in the shape of a substantially rectangular frame on the inner surface. The gasket 33 seals between the front surface of the peripheral portion of the refrigerator compartment 12 (see FIG. 1B) of the heat insulation box 2 (see FIG. 1B) and the heat insulation door 4. With this structure, intrusion of heat from the outside into the refrigerator 1 is suppressed, and cold air in the refrigerator is prevented from escaping to the outside.

また、断熱扉４の庫内側の面には、例えば、卵を収納する収納ケース５１、調味料等を収納する収納ケース５２、５３やペットボトル等を収納する収納ケース５４、５５等が配設されている。図示したように、断熱扉４の内面板材３２の一部が庫内側へと突出した突出部３７、５６が複数形成され、上記収納ケース５１〜５５の受け部等として用いられている。   In addition, on the inner surface of the heat insulating door 4, for example, a storage case 51 for storing eggs, storage cases 52 and 53 for storing seasonings, storage cases 54 and 55 for storing plastic bottles, and the like are disposed. Has been. As shown in the drawing, a plurality of projecting portions 37 and 56 in which a part of the inner surface plate 32 of the heat insulating door 4 protrudes to the inside of the cabinet are formed and used as receiving portions for the storage cases 51 to 55.

図５に示すように、内面板材３２の第２の平坦面３２Ｂは卵の収納ケース５１の上方に配設されている。卵の収納ケース５１には、例えば、冷蔵庫１の奥行方向に卵を立てて収納する収納孔６１、６２が配列されている。そして、庫内側の収納孔６１では、使用者は、上方に配設された突出部３７に当たることなく容易に卵の出し入れ作業を行うことが出来る。一方、断熱扉４側の収納孔６２では、使用者は、上方に配設された第２の平坦面３２Ｂ及び突出部３７に卵が当たることなく卵の出し入れ作業を行う必要がある。   As shown in FIG. 5, the second flat surface 32 </ b> B of the inner plate 32 is disposed above the egg storage case 51. In the egg storage case 51, for example, storage holes 61 and 62 for storing eggs in the depth direction of the refrigerator 1 are arranged. And in the storage hole 61 inside a store | warehouse | chamber, the user can perform the operation | work of putting in / out of an egg easily, without contacting the protrusion part 37 arrange | positioned upwards. On the other hand, in the accommodation hole 62 on the heat insulating door 4 side, the user needs to perform the operation of putting in and out the egg without hitting the second flat surface 32B and the protruding portion 37 disposed above.

上述したように、断熱扉４の厚みを確保するため第２の平坦面３２Ｂは、庫内側へと傾斜して配設されている。例えば、ＬＬサイズ等の大きな卵を収納した場合でも、卵と第２の平坦面３２Ｂとが当たらない様に、第２の平坦面３２Ｂの下側の折り曲げ箇所は設計されている。そして、第１の平坦面３２Ａと第２の平坦面３２Ｂとの成す角度αが、１３５°より大きくなるように、第２の平坦面３２Ｂは成形されている。   As described above, in order to ensure the thickness of the heat insulating door 4, the second flat surface 32 </ b> B is disposed to be inclined toward the inner side of the warehouse. For example, even when a large egg of LL size or the like is stored, the bent portion below the second flat surface 32B is designed so that the egg does not hit the second flat surface 32B. The second flat surface 32B is formed such that the angle α formed by the first flat surface 32A and the second flat surface 32B is greater than 135 °.

つまり、角度αがＣ面加工時の１３５°より大きくなることで、使用者による卵の出し入れ作業が容易になる。そして、断熱扉４と上記角度αとはトレードオフの関係にあるが、上述した結露の問題が解決できる範囲にて、角度αが大きくなるように第２の平坦面３２Ｂが成形されている。その結果、使用者は、収納ケース５１の収納孔６２に卵を出し入れする際に、卵を寝かせ過ぎることなく取り扱うことができるので、使用者の利便性が確保される。また、卵の収納ケース５１の位置を下方に移動することなく使用可能となり、上述した成形金型の改造も容易となり、成形金型の投資費用が大幅に増大することを回避できる。   That is, when the angle α is larger than 135 ° at the time of processing the C surface, the user can easily move the egg in and out. And although the heat insulation door 4 and the said angle (alpha) are in a trade-off relationship, the 2nd flat surface 32B is shape | molded so that the angle (alpha) may become large in the range which can solve the problem of the dew condensation mentioned above. As a result, the user can handle the eggs without putting them too much when putting them in and out of the storage holes 62 of the storage case 51, so that convenience for the user is ensured. Further, the egg storage case 51 can be used without being moved downward, and the above-described molding die can be easily remodeled, so that the investment cost of the molding die can be prevented from significantly increasing.

尚、本実施形態では、断熱扉４の上方側辺に凹みハンドル部５が配設される場合について説明したがこの場合に限定するものではない。例えば、断熱扉４の幅方向の左右側面や断熱扉４の下方側面に凹みハンドル部５が配設される場合でも、上述した第２の平坦面３２Ｂが内面板材３２に配設されることで同様な効果が得られる。   In addition, although this embodiment demonstrated the case where the recessed handle part 5 was arrange | positioned by the upper side of the heat insulation door 4, it does not limit to this case. For example, even when the recessed handle portion 5 is provided on the left and right side surfaces in the width direction of the heat insulating door 4 or the lower side surface of the heat insulating door 4, the second flat surface 32B described above is provided on the inner surface plate 32. Similar effects can be obtained.

また、冷蔵庫１の冷蔵室１２の開口を塞ぐ断熱扉４に凹みハンドル部５が設けられる場合について説明したがこの場合に限定するものではない。例えば、冷蔵庫１の冷凍室１１の開口を塞ぐ断熱扉３に上述した凹みハンドル部５と同じ構造の凹みハンドル部が設けられる場合でも同様な効果が得られる。その他、本発明の要旨を逸脱しない範囲で、種々の変更実施が可能である。   Moreover, although the case where the recessed handle part 5 was provided in the heat insulation door 4 which block | closes the opening of the refrigerator compartment 12 of the refrigerator 1 was demonstrated, it does not limit to this case. For example, the same effect can be obtained even when a recessed handle portion having the same structure as the recessed handle portion 5 described above is provided on the heat insulating door 3 that closes the opening of the freezer compartment 11 of the refrigerator 1. In addition, various modifications can be made without departing from the scope of the present invention.
