Description

本発明は、注入時に流動性の性質を備え、一定時間経過後に発泡、硬化する断熱材の充填に適した冷蔵庫に関する。 The present invention relates to a refrigerator that has a fluid property at the time of pouring and is suitable for filling a heat insulating material that foams and hardens after a certain period of time.

現在、冷蔵庫の断熱材としては一般にウレタンフォームが使用されている。ウレタンフォームは充填時に流動性の性状を備え、一定時間経過後に発泡、硬化することで、外箱と内箱の間に断熱層が作られるようになっている。 Currently, urethane foam is generally used as a heat insulating material for refrigerators. Urethane foam has fluid properties at the time of filling, and is foamed and hardened after a lapse of time, so that a heat insulating layer is formed between the outer box and the inner box.

ウレタンフォームの原液は、例えば、特許文献１に示すように冷蔵庫本体を前方へ倒して伏せた状態とした裏面側の孔からウレタン注入機によって内部へ注入され充填されるようになっている。
特開２０００−１９３３６３号公報 For example, as shown in Patent Document 1, the urethane foam stock solution is injected into the interior by a urethane injector from a hole on the back side in which the refrigerator main body is tilted forward and turned down.
JP 2000-193363 A

ウレタン注入機によって外箱と内箱の間に断熱材原液を充填する時に全領域にわたって隙間なく充填されることが望ましいが、庫内を構成する内箱は、例えば、棚取付用のガイド部、仕切部材取付け用の取付部等の凹凸を有している。 It is desirable to fill the entire region without gaps when filling the insulating material stock solution between the outer box and the inner box by the urethane injecting machine, but the inner box constituting the inside of the warehouse is, for example, a guide part for shelf mounting, It has irregularities such as an attachment portion for attaching the partition member.

仕切部材取付用の取付部は、場所で示すと図３、Ａ部の内側にあたる部分で、その内側の部分を拡大して示したのが図６である。 The attachment part for attaching the partition member is a part corresponding to the inner side of FIG. 3 in FIG. 3 in terms of location, and FIG. 6 shows the inner part in an enlarged manner.

仕切部材取付け用の取付部１０１は、外箱１０３と内箱１０５とで形成された内部空間内で前方となる出し入れ口１０７側に大きくＬ形状に突出する配置となるため、図示の如く前方へ倒して伏せた状態として外箱１０３に設けられた注入口１０９から矢印の如く断熱材原液を充填する時に、図面下側には円滑に流れるようになる。反面、図面上側には前記取付部１０１が壁となってその壁を越えるまで流れが塞ぎ止められ上方への円滑な充填が得られにくい面があった。 The attachment portion 101 for attaching the partition member is disposed so as to protrude in a large L-shape toward the loading / unloading port 107 which is the front in the internal space formed by the outer box 103 and the inner box 105, and therefore, forward as illustrated. When the heat-insulating material stock solution is filled as shown by the arrow from the inlet 109 provided in the outer box 103 in a state of being tilted and turned down, it smoothly flows to the lower side of the drawing. On the other hand, on the upper side of the drawing, there is a surface where the mounting portion 101 becomes a wall and the flow is blocked until it exceeds the wall, and smooth filling upward is difficult to obtain.

このために、時として取付部上側周辺部位に隙間が発生する等の不具合をかかえる等の問題を有する。 For this reason, there are problems such as occasional problems such as the occurrence of a gap in the upper peripheral portion of the mounting portion.

この場合、注入口を多数設けてそこから充填すればよいではないかという考えも成り立つが、各注入口からウレタン注入機によって同時に充填するためには専用の充填治具が必要となる等コストの面、あるいは各注入口の後処理の面でそれぞれ望ましくない。 In this case, the idea that a lot of injection ports may be provided and filled from there is also valid, but a dedicated filling jig is required to simultaneously fill from each injection port with a urethane injection machine. This is undesirable in terms of the surface or the post-treatment surface of each inlet.

そこで、本発明にあっては一箇所の注入口から、断熱材原液の円滑な充填作業を可能とした冷蔵庫を提供することを目的としている。 Then, in this invention, it aims at providing the refrigerator which enabled the smooth filling operation | work of the heat insulating material undiluted | stock solution from one inlet.

前記目的を達成するために本発明にあっては、外箱と、外箱の内側に配置され庫内を構成する内箱と、外箱及び内箱とにより形成された内部空間内に向かって前記内箱から突出した左右一対の仕切部材取付部と、その左右一対の仕切部材取付部にそれぞれ両端が取付けられた仕切部材とを有し、
前記内部空間内に突出した仕切部材取付部は、内部空間内に充填される注入口からの断熱材原液を直接受け止め上方及び下方へ向けて誘導する断熱材誘導受面を備えていることを特徴とする。 In order to achieve the above-mentioned object, in the present invention, toward the inside space formed by the outer box, the inner box arranged inside the outer box and constituting the interior, and the outer box and the inner box. A pair of left and right partition member mounting portions protruding from the inner box, and a partition member having both ends attached to the pair of left and right partition member mounting portions,
The partition member mounting portion protruding into the internal space has a heat insulating material receiving surface that directly receives the heat insulating material stock solution from the inlet filled in the internal space and guides it upward and downward. And

本発明によれば、注入口から充填される断熱材原液を断熱材誘導受面によって直接受け止めた後、上方及び下方へ向けて誘導することができる。このため、一箇所の注入口であっても断熱材原液を円滑に無理なく充填することができるようになる。 According to the present invention, after the heat insulating material stock solution filled from the inlet is directly received by the heat insulating material receiving surface, it can be guided upward and downward. For this reason, even if it is one injection port, it becomes possible to fill the heat insulating material stock solution smoothly and without difficulty.

本発明にあっては第１に、前記断熱材誘導受面を、仕切部材取付部と別部材によって形成すると共に外箱と内箱をつなぐ合わせ目に向かって傾斜する傾斜面を備えた組み合わせ形状とすることで、仕切部材取付部の加工成形を容易にすることと、傾斜面に沿って充填剤を充填することで外箱と内箱の合わせ目へのシール材の充填作用が容易に行えるようにする。 In the present invention, firstly, the heat insulating material guide receiving surface is formed by a partition member mounting portion and a separate member, and has a combined shape including an inclined surface that is inclined toward a joint that connects the outer box and the inner box. By doing so, it is easy to process and mold the partition member mounting portion, and by filling the filler along the inclined surface, the sealing material can be easily filled in the joint between the outer box and the inner box. Like that.

第２に、前記内部空間内に設けられる開閉扉のドアヒンジ用の取付け金具を、前方内壁面と接触し合う板状の取付部とその板状の取付部の両端から後方へ屈曲した一対の屈曲部とにより断面コ字状に形成し、その一対の屈曲部に断熱材原液充填時の流れ方向に向かって貫通した切り起こし開放口を設けることで、断熱材原液の流れを阻害することなく、しかも、断熱材の内部に埋設される一対の屈曲部及び切り起こし片によるアンカー機能によって、開閉扉の負荷が働く取付け金具の強固な取付け状態が長期にわたり安定して得られるようにする。 Secondly, a mounting bracket for the door hinge of the open / close door provided in the internal space is bent in a plate-shaped mounting portion that comes into contact with the front inner wall surface and from both ends of the plate-shaped mounting portion to the rear. By forming a cut-and-raised opening opening penetrating in the flow direction at the time of filling the heat insulating material stock solution in the pair of bent portions without obstructing the flow of the heat insulating material raw solution, In addition, the anchor function of the pair of bent portions and the cut-and-raised pieces embedded in the heat insulating material enables a stable mounting state of the mounting bracket on which the load of the opening and closing door is stably obtained over a long period of time.

以下、図１乃至図５の図面を参照しながら本発明の実施形態について具体的に説明する。 Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. 1 to 5.

The front joint 9 between the outer box 3 and the inner box 5 is sealed from the inside by a sealing material, while the inner space is filled with a heat insulating material (not shown) over the entire region.

断熱材は充填時は流動性で一定時間経過後に発泡，硬化するようウレタンフォーム等が用いられている。 Urethane foam or the like is used so that the heat insulating material is fluid when filled and foams and hardens after a certain period of time.

内箱５には、両サイドに棚板取付け用の凹凸に形成された棚板取付部５ｅと後述する仕切部材取付部２１が設けられる一方、仕切部材１１と仕切壁１３がそれぞれ後付けによって取付けられている。したがって、仕切部材１１と仕切壁１３とによって第１、第２、第３の庫内１５、１７、１９が構成され、第３の庫内１９は仕切壁１３によって独立した庫内に作られている。 The inner box 5 is provided with shelf plate mounting portions 5e formed on both sides of the concave and convex portions for mounting the shelf plates and a partition member mounting portion 21 to be described later, while the partition member 11 and the partition wall 13 are respectively attached by retrofitting. ing. Therefore, the partition member 11 and the partition wall 13 constitute the first, second, and third chambers 15, 17, and 19, and the third chamber 19 is made by the partition wall 13 in an independent chamber. Yes.

仕切部材１１は角柱状に形成され両端は、内箱５から内部空間内にＬ形状に突出した仕切部材取付部２１に取付けねじ２３によって固定支持されている。 The partition member 11 is formed in a prismatic shape, and both ends thereof are fixedly supported by mounting screws 23 on a partition member mounting portion 21 protruding in an L shape from the inner box 5 into the internal space.

仕切部材取付部２１は、図１に示すように外箱３の背面パネル３ｂに設けられた注入口２５からの断熱材原液を直接受け止め矢印イの如く上方及び下方へ向けて誘導する断熱材誘導受面２７を備えている。 As shown in FIG. 1, the partition member mounting portion 21 directly receives the heat insulating material stock solution from the inlet 25 provided on the back panel 3b of the outer box 3 and guides it upward and downward as indicated by arrows a. A receiving surface 27 is provided.

断熱材誘導受面２７は、仕切部材取付部２１と一体の形状としてもよいが、この実施形態では別部材で作られたガイド部材２９によって平坦面に作られている。 The heat insulating material guide receiving surface 27 may be formed integrally with the partition member mounting portion 21. In this embodiment, the heat insulating material guide receiving surface 27 is made flat by a guide member 29 made of a separate member.

ガイド部材２９は、図４に示す如くＬ形状の仕切部材取付部２１に嵌合セットする嵌合穴３３を有し、その嵌合穴３３を強制的に挿入することで装着可能となっていて、前記断熱材誘導受面２７の外に、図１に示すように外箱３と内箱５をつなぐ合せ目９に向かって傾斜面３１を備えている。これにより、傾斜面３１を利用することで、例えば、矢印ロ方向からガイド部材２９の下方となる合せ目９をシール用のガンによってシールする際にそのシール作業が無理なく行えるようになっている。 As shown in FIG. 4, the guide member 29 has a fitting hole 33 to be fitted and set in the L-shaped partition member mounting portion 21 and can be mounted by forcibly inserting the fitting hole 33. In addition to the heat insulating material guide receiving surface 27, an inclined surface 31 is provided toward the seam 9 connecting the outer box 3 and the inner box 5 as shown in FIG. Thus, by using the inclined surface 31, for example, when the seam 9 below the guide member 29 is sealed with a sealing gun from the direction of arrow B, the sealing operation can be performed without difficulty. .

一方、仕切壁１３の一方の側部には図５に示す如く開閉扉のドアヒンジ３７を取付けるための取付け金具３９が設けられている。 On the other hand, an attachment fitting 39 for attaching a door hinge 37 of the door is provided on one side of the partition wall 13 as shown in FIG.

取付け金具３９は、図１に示す如く前方内壁面と接触し合う板状の取付部３９ａとその板状の取付部３９ａの両端から後方へ９０度屈曲した一対の屈曲部３９ｂとにより断面コ字状に形成され、その一対の屈曲部３９ｂに断熱材原液充填時の流れ方向（矢印ハ）に向かって貫通した切り起こし開放口４１が設けられた形状となっている。 As shown in FIG. 1, the mounting bracket 39 has a plate-shaped mounting portion 39a that comes into contact with the front inner wall surface and a pair of bent portions 39b bent 90 degrees rearward from both ends of the plate-shaped mounting portion 39a. A pair of bent portions 39b are provided with a cut and raised opening 41 penetrating in the flow direction (arrow C) when the heat insulating material stock solution is filled.

これにより、断熱材の内部に埋設される一対の屈曲部３９ｂとその屈曲部３９ｂと方向が異なる切り起こし開放口４１の切り起こし片４１ａとによって確実で強固なアンカー機能が確保されるようになっている。 Accordingly, a reliable and strong anchor function is secured by the pair of bent portions 39b embedded in the heat insulating material and the cut and raised pieces 41a of the opening portions 41 having different directions from the bent portions 39b. ing.

このように構成された冷蔵庫によれば、図１に示すように前方に倒して伏せた姿勢の冷蔵庫本体１に対して注入口２５から断熱材原液を矢印イの如く充填すれば断熱材原液は断熱材誘導受面２７によって上方及び下方へ向け円滑に流れるようになる。また、取付け金具３９に達した断熱材原液は切り起こし開放口４１によって支障なく円滑に流れるようになり、迅速な断熱材の充填作業が行なえる。 According to the refrigerator configured as described above, if the heat insulating material concentrate is filled from the inlet 25 into the refrigerator main body 1 in a posture that is tilted forward and turned down as shown in FIG. The heat insulating material guide receiving surface 27 smoothly flows upward and downward.
