Description

【0001】
【発明の属する技術分野】
本発明は、貯蔵室に収納された食材を所定の温度下にて冷蔵又は冷凍保存すべく用いられる冷蔵庫に関する。
【0002】
【従来の技術】
食材の貯蔵のために家庭内で広く用いられている冷蔵庫は、食材毎、貯蔵温度毎に設けた貯蔵室の前側開口部に、該貯蔵室内への食材の搬出入のために開閉される扉(前面扉)を備えて構成されている。
【0003】
このような冷蔵庫の前面扉には、貯蔵室内部の保温性能を高め、省エネルギを図るために、高い断熱性を有することが要求され、また一方、支持構造の簡素化を図り、軽快な開閉操作感を得るために、可及的に軽量化することが要求されており、これらの要求に応え得るものとして、従来から、貯蔵室の内側に面する内板と、外側に面する外板と、これらの側縁を連絡する枠板とにより中空の筐体を構成し、この筐体の内側空間内に発泡性を有する断熱材を充填してなる前面扉が用いられている。前記断熱材の充填は、ウレタン樹脂等の発泡性樹脂を前記空間内に適量導入し、その後に発泡せしめて実現されている。
【0004】
【発明が解決しようとする課題】
さて、以上の如く構成された前面扉の内部には、例えば、扉の閉め忘れ感知センサ用の磁石等の構成部品が取付けられることがある。前記閉め忘れ感知センサは、貯蔵室の周縁に設けられた磁気センサであり、前記磁石は、前面扉の閉止時に閉め忘れ感知センサに対向するように、前記内板の内面に接して周縁部近傍に固定されている。
【0005】
この構成により前記閉め忘れ感知センサの出力は、前面扉が閉止されている状態では、前記磁石の接近により増大し、前面扉が開放されている状態では、前記磁石の離反により減少するから、例えば、前記出力の減少に応じて、警報用のLEDの点灯、警報音の発生等の警報動作を行わせることにより、前面扉の閉め忘れを使用者に報知し、無為な電力消費を削減することが可能となる。
【0006】
ところが、前記磁石の内板への取付けは、外板及び枠板とによる筐体の組立て前になされるため、取付け時点又は組立て途中における位置ずれ、取付け忘れ等の取付け不良の発生を、前記組立ての後に断熱材を充填して構成される前面扉の外側から発見することは困難であり、冷蔵庫本体への前面扉の組み付け後、閉め忘れ感知センサの動作試験の段階において取付け不良が発見されて、前面扉の組み直しを強いられ、歩留りの低下を招来するという問題があった。
【0007】
本発明は斯かる事情に鑑みてなされたものであり、閉め忘れ感知センサ用の磁石等、前面扉の内側に内板に接して固定される構成部品の取付け不良の有無を、組立てられた前面扉の外側からの目視検査により、容易にしかも確実に判定することができ、取付け不良品の誤った組み付けを未然に防止することが可能な冷蔵庫を提供することを目的とする。
【0008】
【課題を解決するための手段】
本発明に係る冷蔵庫は、外板及び内板と、これらの側縁を連絡する枠板との間に形成された空間内に、発泡性を有する断熱材を充填してなる前面扉と、該前面扉の内部に、前記内板に接して固定された構成部品とを備える冷蔵庫において、前記内板の前記構成部品により閉止される位置に、前記断熱材が発泡時に発生するガスを外部に放出するガス抜き孔が形成してあることを特徴とする。
【0009】
本発明においては、前面扉の内部に内板に接して固定される構成部品の固定位置に、該固定位置に正しく固定された構成部品により塞がれ、取付け不良の発生時に、内板、外板及び枠板により形成される空間内に開口するガス抜き孔を形成しておき、前記空間内にて発泡する断熱材が前記ガス抜き孔から漏れ出すか否かにより取付け不良の有無を判定可能とし、取付け不良が生じた前面扉の誤った組み付けを未然に防止する。
【0010】
また本発明に係る冷蔵庫は、前記構成部品が、前面扉の閉め忘れ感知センサ用の磁石であることを特徴とする。
【0011】
本発明においては、重量物であり、内板への取付け後に位置ずれし易い構成部品としての閉め忘れ感知センサ用の磁石の固定位置にガス抜き孔を設け、該磁石の取付け不良の有無を確実に判定する。
【0012】
更に本発明に係る冷蔵庫は、前記磁石が、前記内板の内面に設けた凹所に嵌め込み固定してあることを特徴とする。
【0013】
本発明においては、閉め忘れ感知センサ用の磁石を、内板の内面の該当位置に設けた凹所に嵌め込み固定して取付け、この取付けの後、外板及び枠板との組立て段階での位置ずれの発生を未然に防止する。なお、前記凹所に嵌め込まれた磁石の固定を、これの上部から貼着されたテープにより補強することにより、前記位置ずれの発生をより有効に防ぎ得る。
【0014】
【発明の実施の形態】
以下本発明をその実施の形態を示す図面に基づいて詳述する。図1は、本発明に係る冷蔵庫の外観斜視図である。本図に示す冷蔵庫1は、本体10の内部を分割し、食材毎、貯蔵温度毎に設けられた5つの貯蔵室(図示せず)を備えており、左側の上下に並ぶ2つの貯蔵室の前部を、前記本体10の左側縁に沿う枢軸回りに枢支された各別の前面扉11,12により開閉自在に覆い、また、右側の上下に並ぶ3つの貯蔵室の前部を、前記本体10の右側縁に沿う枢軸回りに枢支された各別の前面扉13,14,15により開閉自在に覆って構成されている。
【0015】
本発明に係る冷蔵庫1の特徴は、以上の如き前面扉11〜15の構造にあり、以下この構造について、右側中央の前面扉14を例として説明する。図2は、前面扉14の平面図であり、図3は、図2の要部拡大図、図4は、図2のIV−IV線による部分拡大断面図である。
【0016】
図4に示す如く前面扉14は、貯蔵室の内側に面する内板(ドアバッグ)2と、同じく外側に面し、化粧板を兼ねる外板3と、これらの側縁を連絡する枠板(ドアキャップ)4とを備え、前記内板2、外板3及び枠板4により形成された中空の筐体の内側空間内に発泡性樹脂を用いてなる断熱材5を充填し、高い断熱性と軽量化とを併せて実現した構成となっている。
【0017】
図2は、内板2の側から見た平面図である。本図に示す如く矩形平板状をなす内板2は、周縁のやや内側に全周に亘って周設されたガスケット溝20を備えている。このガスケット溝20は、図4に示す如く、内板2の内面側に凹む円形断面の溝であり、前面扉14の閉止時に対応する貯蔵室の周縁に弾接してシール作用をなすガスケット(図示せず)が嵌め込み固定されるようになしてある。
【0018】
図2に示す如く、内板2の一側短辺に沿うガスケット溝20の内側には、磁石固定部21が設けてある。図3は、磁石固定部21近傍の拡大図、図4は、磁石固定部21を含む断面図であり、図2及び図3に示す如く磁石固定部21は、前記ガスケット溝20に沿う方向を長手方向とする矩形の底面を有し、図4に示す如く、内板2の内面側から見て外向きに張り出す凹部として一体成形されている。
【0019】
このような磁石固定部21の底面の幅方向一側には、図4に示す如く半円形の断面を有し、内板2の内面側に張り出すストッパ縁22が、図3に示す如く長手方向に沿って延設されている。また前記ストッパ縁22から離れた側の磁石固定部21の側壁の上縁には、内板2の内面側に張り出すアンダーカット部23が適長に亘って設けられている。
【0020】
また、磁石固定部21の底面の中央部には、小径のガス抜き孔24が、内板2を内外に貫通するように形成されている。内板2には、前記ガス抜き孔24と同様に内外に貫通する複数のガス抜き孔25,25…が、図1に示す如く、全面の複数か所に適宜に散在するように形成されている。
【0021】
このように構成された磁石固定部21には、閉め忘れ感知センサ用の磁石26が固定されている。この磁石26は、図4に示す如く、前記ストッパ縁22と前記アンダーカット部23との間に嵌め込まれ、内板2の内面となる前記磁石固定部21の底面に接した状態に固定されている。このとき、磁石固定部21の底面に形成されたガス抜き孔24は、前記磁石26により閉止される。
【0022】
図5は、磁石26の固定手順の説明図である。磁石26は矩形断面を有しており、図5(a)に示す如き傾斜姿勢にてストッパ縁22とアンダーカット部23との間に挿入され、アンダーカット部23に近い上角部を図中に矢符にて示す如く押圧することにより、該アンダーカット部23及び前記ストッパ縁22の弾性変形を伴って磁石固定部21内に嵌め込まれ、図5(b)及び図4に示す如く固定される。
【0023】
以上の如き磁石26の固定は、単純な押し込み操作により簡易に実現され、また磁石26の固定姿勢は、弾性復帰したストッパ縁22及びアンダーカット部23が対応する角部に当接することにより拘束されるから、この後に行われる前記外板3及び枠板4の組立て、並びに前記断熱材5の充填の間においても、殆ど位置ずれすることなく維持される。なお、図5(b)中に2点鎖線にて示す如く、前述の如く嵌め込まれた磁石26の上部に固定用のテープ27を貼着し、固定状態の強化を図ることにより、前記位置ずれの発生をより確実に防止することができる。
【0024】
前面扉14は、以上の如く磁石26が固定された内板2と、前記外板3及び枠板4とを組立て、これらにより形成される空間内に断熱材5を充填して構成される。断熱材5の充填は、前記空間内にウレタン樹脂等の発泡性樹脂を適量導入し、所定の発泡条件下にて発泡せしめて実現される。このとき、内板2に設けられた前記ガス抜き孔25,25…は、前記発泡に伴って前記空間内に発生するガスを外部に放出する作用をなし、良好な発泡により十分に膨らむ発泡性樹脂により、多数の空洞を有し高い断熱性を有する断熱材5が、前記空間内に密に充填された状態に構成される。
【0025】
ここで、前記ガス抜き孔25,25…と同様のガス抜き孔24は、磁石固定部21の底面にも形成されているが、このガス抜き孔24は、磁石固定部21に前述の如く固定された磁石26により閉止されているため、前記発泡に伴うガスの放出はなされない。ところが、磁石26の取付け忘れ、位置ずれ等の取付け不良が生じ、前記ガス抜き孔24が開口状態にある場合、このガス抜き孔24においても前記ガスの放出がなされる。
【0026】
図6は、ガス抜き孔24の動作説明図であり、磁石26の取付けを忘れた状態で断熱材5の発泡がなされた後の状態が示されている。このとき、磁石固定部21の底面に形成されたガス抜き孔24は、図示の如く、内板2の内外に開口しており、内部での断熱材5の発泡に伴って発生するガスが、前記ガス抜き孔24を経て外部に放出され、この放出ガスと共に断熱材5を構成する樹脂材料が少量噴出し、ガス抜き孔24の開口部周辺にて固まって、図示の如き樹脂塊28が生成される。
【0027】
このように生成される樹脂塊28は、磁石固定部21への磁石26の取付けが不良であり、該磁石26によりガス抜き孔24が閉止されていないことを示すものであり、断熱材5の発泡を終えた後においては、前面扉14の外側から目視検査により容易に発見することができる。従って、樹脂塊28の生成の有無を調べることにより、前記磁石26の取付け不良の有無を、容易にしかも確実に判定することができ、取付け不良が生じた前面扉14の誤った組み付けを未然に防止することができる。
【0028】
なお、前記樹脂塊28と同様の樹脂塊は、他のガス抜き孔25,25…の周辺にも生成されるが、これらの樹脂塊は、磁石26の取付け不良に起因するものではないから、断熱材5の発泡完了後に除去すればよい。
【0029】
以上の実施の形態においては、前面扉14の内部に内板に接して固定された構成部品として、閉め忘れ感知センサ用の磁石26を備える場合について説明したが、他の構成部品を備える場合においても本発明の適用は可能である。
【0030】
また以上の実施の形態においては、前面扉14について説明したが、冷蔵庫1に備えられた他の前面扉11,12,13,15に対しても本発明の適用は可能であり、更に、前方への引き出し及び後方への押し込みにより開閉動作を行う構成とした前面扉に対しても本発明の適用は可能であり、同様の効果が得られることは言うまでもない。
【0031】
【発明の効果】
以上詳述した如く本発明に係る冷蔵庫においては、前面扉の内板に接して固定される構成部品により内側から閉止される位置にガス抜き孔を形成したから、このガス抜き孔の周辺を外部から目視検査することにより、前記構成部品の取付け不良の有無を、容易にしかも確実に判定することができ、取付け不良が生じた前面扉が誤って組み付けられることを未然に防止して、歩留りの向上を図ることができる。
【0032】
また、ガス抜き孔周辺の目視検査により閉め忘れ感知センサ用の磁石の取付け不良の有無を判定するようにしたから、内板への取付け後に位置ずれし易い前記磁石の取付け不良を確実に発見することができる。
【0033】
更に、閉め忘れ感知センサ用の磁石を、内板の内面に設けた凹所に嵌め込み固定したから、簡易な取付けにより取付け後の位置ずれの発生を未然に防止することが可能となる等、本発明は優れた効果を奏する。

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail with reference to the drawings illustrating embodiments thereof. FIG. 1 is an external perspective view of a refrigerator according to the present invention. The refrigerator 1 shown in the figure is divided into the interior of the main body 10 and includes five storage chambers (not shown) provided for each food and for each storage temperature. The front part is covered with a separate front door 11, 12 pivotally supported around the pivot along the left edge of the main body 10, and the front part of the three storage chambers lined up and down on the right side The front doors 13, 14, 15 are pivotally supported around the pivot along the right edge of the main body 10 so as to be freely opened and closed.
[0015]
The feature of the refrigerator 1 according to the present invention lies in the structure of the front doors 11 to 15 as described above. Hereinafter, this structure will be described by taking the front door 14 at the center on the right side as an example. 2 is a plan view of the front door 14, FIG. 3 is an enlarged view of a main part of FIG. 2, and FIG. 4 is a partially enlarged cross-sectional view taken along line IV-IV of FIG.
[0016]
As shown in FIG. 4, the front door 14 has an inner plate (door bag) 2 facing the inside of the storage room, an outer plate 3 also facing the outside and also serving as a decorative plate, and a frame plate connecting these side edges. (Door cap) 4, and a heat insulating material 5 made of foamable resin is filled into the inner space of a hollow casing formed by the inner plate 2, the outer plate 3, and the frame plate 4, thereby providing high heat insulation. It has a configuration that combines both performance and weight reduction.
[0017]
FIG. 2 is a plan view seen from the inner plate 2 side. As shown in this figure, the inner plate 2 having a rectangular flat plate shape has a gasket groove 20 provided around the entire circumference slightly inside the periphery. As shown in FIG. 4, the gasket groove 20 is a groove having a circular cross section that is recessed on the inner surface side of the inner plate 2, and is a gasket that elastically contacts the peripheral edge of the corresponding storage chamber when the front door 14 is closed (see FIG. 4). (Not shown) is fitted and fixed.
[0018]
As shown in FIG. 2, a magnet fixing portion 21 is provided inside the gasket groove 20 along one short side of the inner plate 2. FIG. 3 is an enlarged view of the vicinity of the magnet fixing portion 21, and FIG. 4 is a cross-sectional view including the magnet fixing portion 21, and the magnet fixing portion 21 has a direction along the gasket groove 20 as shown in FIGS. As shown in FIG. 4, it has a rectangular bottom surface in the longitudinal direction, and is integrally formed as a recess that protrudes outward as viewed from the inner surface side of the inner plate 2.
[0019]
On one side in the width direction of the bottom surface of the magnet fixing portion 21 as described above, a stopper edge 22 having a semicircular cross section as shown in FIG. 4 and projecting to the inner surface side of the inner plate 2 is long as shown in FIG. It extends along the direction. Further, an undercut portion 23 that protrudes to the inner surface side of the inner plate 2 is provided over an appropriate length on the upper edge of the side wall of the magnet fixing portion 21 on the side away from the stopper edge 22.
[0020]
Further, a small-diameter vent hole 24 is formed at the center of the bottom surface of the magnet fixing portion 21 so as to penetrate the inner plate 2 inward and outward. As shown in FIG. 1, the inner plate 2 is formed with a plurality of gas vent holes 25, 25... Penetrating inward and outward in the same manner as the gas vent holes 24 so as to be appropriately scattered at a plurality of locations on the entire surface. Yes.
[0021]
The magnet 26 for the forgetting to close detection sensor is fixed to the magnet fixing portion 21 configured as described above. As shown in FIG. 4, the magnet 26 is fitted between the stopper edge 22 and the undercut portion 23 and is fixed in contact with the bottom surface of the magnet fixing portion 21 which is the inner surface of the inner plate 2. Yes. At this time, the gas vent hole 24 formed in the bottom surface of the magnet fixing portion 21 is closed by the magnet 26.
[0022]
FIG. 5 is an explanatory diagram of a procedure for fixing the magnet 26. The magnet 26 has a rectangular cross section, and is inserted between the stopper edge 22 and the undercut portion 23 in an inclined posture as shown in FIG. Is pressed into the magnet fixing portion 21 with elastic deformation of the undercut portion 23 and the stopper edge 22 and fixed as shown in FIGS. 5B and 4. The
[0023]
The fixing of the magnet 26 as described above is easily realized by a simple pushing operation, and the fixing posture of the magnet 26 is restrained by the elastically recovered stopper edge 22 and the undercut portion 23 coming into contact with the corresponding corner portions. Therefore, even during the assembly of the outer plate 3 and the frame plate 4 and the filling of the heat insulating material 5 performed thereafter, the position is maintained with little displacement. In addition, as shown by a two-dot chain line in FIG. 5 (b), a fixing tape 27 is attached to the upper part of the magnet 26 fitted as described above, and the fixed state is strengthened, whereby the positional deviation is achieved. Can be more reliably prevented.
[0024]
The front door 14 is constructed by assembling the inner plate 2 to which the magnet 26 is fixed, the outer plate 3 and the frame plate 4 as described above, and filling the space formed by them with the heat insulating material 5. Filling the heat insulating material 5 is realized by introducing an appropriate amount of a foamable resin such as urethane resin into the space and foaming under a predetermined foaming condition. At this time, the degassing holes 25, 25... Provided in the inner plate 2 have a function of releasing the gas generated in the space along with the foaming to the outside, and the foaming property is sufficiently expanded by good foaming. By the resin, the heat insulating material 5 having a large number of cavities and having high heat insulating properties is configured to be densely filled in the space.
[0025]
Here, the gas vent holes 24 similar to the gas vent holes 25, 25... Are also formed on the bottom surface of the magnet fixing portion 21, but the gas vent holes 24 are fixed to the magnet fixing portion 21 as described above. Since the magnet 26 is closed, no gas is released due to the foaming. However, when the magnet 26 is forgotten to be installed or a mounting failure such as misalignment occurs and the gas vent hole 24 is in the open state, the gas is also released from the gas vent hole 24.
[0026]
FIG. 6 is an explanatory view of the operation of the gas vent hole 24 and shows a state after the heat insulating material 5 is foamed in a state where the attachment of the magnet 26 is forgotten. At this time, the gas vent hole 24 formed in the bottom surface of the magnet fixing portion 21 is opened to the inside and outside of the inner plate 2 as shown in the figure, and the gas generated with the foaming of the heat insulating material 5 inside is as follows. A small amount of the resin material constituting the heat insulating material 5 is ejected to the outside through the gas vent hole 24 and is solidified around the opening of the gas vent hole 24 to form a resin mass 28 as shown in the figure. Is done.
[0027]
The resin mass 28 generated in this manner indicates that the attachment of the magnet 26 to the magnet fixing portion 21 is poor and that the gas vent hole 24 is not closed by the magnet 26, and the heat insulating material 5 After the foaming is finished, it can be easily found from the outside of the front door 14 by visual inspection. Therefore, by examining the presence or absence of the formation of the resin mass 28, it is possible to easily and surely determine whether or not the magnet 26 is attached poorly, and inadvertently assembling the front door 14 in which the attachment failure has occurred. Can be prevented.
[0028]
The resin lump similar to the resin lump 28 is also generated around the other vent holes 25, 25 ..., but these resin lump is not due to poor mounting of the magnet 26, What is necessary is just to remove after completion of foaming of the heat insulating material 5. FIG.
[0029]
In the above embodiment, the case where the forgetting to close sensor 26 is provided as a component fixed in contact with the inner plate inside the front door 14 has been described. The present invention can also be applied.
[0030]
Moreover, in the above embodiment, although the front door 14 was demonstrated, this invention is applicable also to the other front doors 11, 12, 13, 15 with which the refrigerator 1 was equipped, Furthermore, front Needless to say, the present invention can also be applied to a front door that is configured to open and close by pulling out and pushing backward, and the same effect can be obtained.
[0031]
【The invention's effect】
As described above in detail, in the refrigerator according to the present invention, the gas vent hole is formed at the position closed from the inside by the components fixed in contact with the inner plate of the front door. from by visual inspection, the presence or absence of mounting failure of said component, easily and can be reliably determined, then prevented that the mounting defect is assembled incorrectly front door caused, the yield Improvements can be made.
[0032]
In addition, since it is determined whether there is a defective mounting of the magnet for the forgetting to close sensor by visual inspection around the vent hole, the defective mounting of the magnet that is likely to be displaced after mounting on the inner plate is surely detected. be able to.
[0033]
Furthermore, since the magnet for the forgetting to close sensor is fitted and fixed in the recess provided on the inner surface of the inner plate, it is possible to prevent the occurrence of misalignment after installation by simple installation. The invention has an excellent effect.
