Abstract

<P>PROBLEM TO BE SOLVED: To provide a door device of a storage shed causing no erroneous operation by a door switch in doors provided with the door switch and juxtaposed in the vertical direction. <P>SOLUTION: The door switch 20 for controlling an internal apparatus is composed of a sensing part 22 arranged on a vertically opposed one end surface of the vertically juxtaposed doors 16 and 18 and a sensing object part 24 arranged on the other end surface. A pair of magnets 31 and 32 capable of vertically opposing mutual like-poles are arranged in a position separate from an arranging position of the sensing part 22 and the sensing object part 24 in vertically opposed end surfaces of both doors 16 and 18. Since both doors 16 and 18 are mutually separated so that the sensing part 22 and the sensing object part 24 do not vertically overlap by the repulsive action of both magnets 31 and 32 in an opening state of both doors 16 and 18, the erroneous operation of the door switch 20 can be prevented. <P>COPYRIGHT: (C)2004,JPO

Description

【0001】
【発明の属する技術分野】
この発明は、例えば冷蔵庫に開閉可能に配設した複数の扉に付設されて、該扉の開閉状態を検知する内部機器の制御スイッチの誤作動を防ぐようにした貯蔵庫のドア装置に関するものである。
【0002】
【従来の技術】
各種食材等を冷蔵し、保管するための貯蔵庫としての冷蔵庫では、図6に示すように、その本体をなす断熱箱体10に内部画成された複数の収容室12と連通する各開口部14が前面側に開設されると共に、各開口部14を閉成し得る扉16,18が対応して開閉可能に配設されている。前記各扉16,18の回動支点側の端部と断熱箱体10との間には、ヒンジ19が上下方向に所要間隔離間して配設され、該ヒンジ19を支点に扉16,18を回動することにより開口部14が開閉されるようになっている。
【0003】
従来より冷蔵庫に収容品を出し入れするために扉16,18を開放した際に、収容室12内を明るくする庫内灯を点灯させたり、または扉16,18の開放時に収容室12内の冷気が外部に流出するのを少なくするために冷気循環ファンを停止させる制御スイッチ20が、扉16,18に配設されている。この制御スイッチはドアスイッチ20と呼ばれ、2枚の扉16,18が上下方向に並設された冷蔵庫においては、上部扉16における下端面に配設されたスイッチ要素である感知部22と、該感知部22に対向する下部扉18における上端面に配設された別のスイッチ要素である被感知部24との2つのスイッチ要素を一組として、内部機器を制御する構成のドアスイッチ20が知られている(例えば、特許文献1参照)。
【0004】
すなわち、前記ドアスイッチ20は、どちらか一方の扉16,18を開放した際、該扉16,18のスイッチ要素22,24が他方の扉18,16に配設された別のスイッチ要素24,22と離間することで、該ドアスイッチ20はOFFとなり、前記庫内灯を点灯させたり、冷気循環ファンを停止する。また、両扉16,18が閉成することで、両スイッチ要素22,24が整列的に対向して、ドアスイッチ20がONとなることで、前記庫内灯を消灯し、前記冷気循環ファンを作動させるよう制御している。
【0005】
【特許文献1】
実開平1−144790号公報
【0006】
【発明が解決しようとする課題】
しかし、このように上下方向に並設された扉16,18の対向する端面に配設される感知部22と被感知部24とで構成された前記ドアスイッチ20では、上下の両扉16,18を一度に開放した際、該両扉16,18が上下に重なった状態で保持されると、該ドアスイッチ20の感知部22と被感知部24も整列的に対向し、該感知部22は被感知部24を検知して、該ドアスイッチ20はON状態になってしまう。このため、上下の扉16,18が開放状態にあるにも拘わらず、冷気循環ファンを作動させ、収容室12内の冷気を過剰に逃がしてしまうと共に、庫内灯が消灯してしまう欠点がある。また、両扉16,18の最大開放角度は、上下とも所定のストッパ機構にて同一角度に設定されているので、両扉16,18を最大限に開放した際も、両扉16,18は上下に重なった状態で保持され、前記ドアスイッチ20をON状態にしてしまう誤作動を起こす問題も指摘される。
【0007】
【発明の目的】
この発明は、従来の技術に係る貯蔵庫のドア装置に内在する前記問題に鑑み、これらを好適に解決するべく提案されたものであって、上下方向に並設された扉の上下に対向する端面に夫々制御スイッチの要素が配設された扉において、扉開放時における該制御スイッチの誤作動を防止し得る貯蔵庫のドア装置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】
前記課題を克服し、所定の目的を達成するため、本発明に係る貯蔵庫のドア装置は、
本体に内部画成された収容室の開口部を開閉可能に閉成する上下方向に並設された一対の扉を備え、両扉の上下に対向する一方の端面に配設される感知部と、他方の端面に配設される被感知部とからなる内部機器の制御スイッチが付設され、前記感知部と被感知部とが上下に重なることで両扉の閉成状態を検知するようにした貯蔵庫において、
前記両扉を開放した際に、前記感知部と被感知部とが上下に重なるのを規制する規制手段を両扉に設けたことを特徴とする。
【0009】
【発明の実施の形態】
次に、本発明の好適な実施例に係る貯蔵庫のドア装置につき、好適な実施例を挙げて、添付図面を参照して以下に説明する。なお、説明の便宜上、図6に示した貯蔵庫の構成要素と同一の要素については、同一の符号を使用して説明する。また、実施例においては、貯蔵庫として冷蔵庫を挙げて説明するが、このドア装置を用いる対象物としては、冷蔵庫に限らず冷凍庫、温蔵庫、配膳車、オーブン等、扉が回動可能に取付けられると共に、上下方向に少なくとも2枚の扉が並列的に配設され、該扉の開閉に連動して内部機器を制御する必要があるものであればよい。
【0010】
実施例に係るドア装置が配設された冷蔵庫は、図1または図2に示すように、内装40と外装42の間にウレタン等の発泡断熱材を充填してなる本体としての断熱箱体10の内部に、食品や飲料品等を収容する収容室12が内部画成されると共に、該断熱箱体10の上部には機械室44が画成されている。この機械室44には、冷凍機構46が収納され、該冷凍機構46から冷媒が循環供給される冷却器48および冷気循環ファン50が収納される冷却室52が、機械室44と収容室12との間に画成されている。前記収容室12と冷却室52とを連通する吸込み口54が前側に形成されると共に、後側には吹出し口56が形成されており、冷気循環ファン50を回転することにより、吸込み口54から冷却室52に吸込んだ収容室12内空気を、前記冷却器48に強制的に接触させて冷気とした後、該吹出し口56を介して収容室12に吹出すことで、該収容室12を冷却するように構成される。
【0011】
実施例の断熱箱体10には、4つの収容室12が間仕切り板により上下および左右に仕切られると共に、各収容室12の前面に、開口部14が開設されている。また断熱箱体10には、各開口部14を閉成し得るように、上側の開口部14には上部扉16および下側の開口部14には下部扉18が、夫々一方の端縁部をヒンジ19を介して断熱箱体10に回動可能に配設してある。両扉16,18は、矩形箱状に成形された本体部の内部空間に、発泡断熱材を充填して構成される。前記両扉16,18の最大開放角度は、所定の手段で規制されて異なるようになっている。すなわち、図3の右側において上下に並設された扉16,18で示すように、両扉16,18の最大開放角度は所定のストッパ機構(図示せず)にて別々に設定され、夫々の扉16,18を最大限に開放した際に、両扉16,18の上下に対向する端面16a,18aが整列状態で上下に重なることがないよう構成されている。
【0012】
前記ドア装置は、上下の扉16,18の夫々に配設された感知部22と被感知部24からなるドアスイッチ20と、該ドアスイッチ20と同一端面16a,18aの離間した位置に配設される規制手段30としての一対の磁石31,32から構成される。すなわち、前記感知部22は、上部扉16の下端面16aにおけるヒンジ19と近接する位置に配設され、前記被感知部24は、下部扉18の上端面18aにおいて前記感知部22と上下に対向し得る位置に配設される。この感知部22は、リードスイッチ機構の如きものであって、図4に示すように、上部扉16における下端面16aに感知面を隣接させて発泡断熱材に埋め込まれている。そして、前記感知部22から図示しない制御回路に信号を送る配線26が延出し、該配線26は上部扉16内部の発泡断熱材に埋め込まれ、上方のヒンジ19を介して機械室44内へ引き込まれている。前記被感知部24は、マグネットの如く磁性をもつものであって、下部扉18の上端面18aにその一端を隣接させて、発泡断熱材に埋め込まれている。また被感知部24は、上下の扉16,18を閉成することで両扉16,18が上下に整列的に重なった際に、上部扉16に配設された感知部22に対して整列的に重なり、このときに感知部22が被感知部24を検知し、当該ドアスイッチ20が両扉16,18の閉成状態を検知(ON)するようになっている。そして、上下何れかの扉16,18を開放することで感知部22と被感知部24とが離間してドアスイッチ20が非検知(OFF)状態となったときに、前記制御回路は前記冷気循環ファン50を停止したり、図示しない庫内灯を点灯するよう設定されている。
【0013】
前記磁石31,32は、図5に示すように、上部磁石31が上部扉16の前記感知部22から離間した開放端部近傍の同一上端面16aに配設され、該上部磁石31の一端は前記上部扉16を画成する外装材に隣接して発泡断熱材に埋め込まれている。また、下部磁石32は上下の両扉16,18を閉成した状態で、上部扉16に配設された前記上部磁石31に整列的に対向する下部扉18の上端面18aに配設される。すなわち、下部磁石32は、下部扉18の上端面18aにその一端を隣接させて、発泡断熱材に埋め込まれている。両磁石31,32は、同極同士を上下に対向可能に配設され、両扉16,18を開放した状態では、両磁石31,32の反発力によって前記感知部22と被感知部24とが上下に重ならないように、両扉16,18を離間移動させるよう構成される。なお、両磁石31,32の反発力は、両扉16,18をゴム磁石等により閉成位置に保持するのに支障を来さない値に設定される。
【0014】
【実施例の作用】
次に、実施例に係る貯蔵庫のドア装置の作用について説明する。図2に示すように、前記断熱箱体10における各収容室12の各開口部14を閉成するよう上下に配設された扉16,18は、その閉成時において、両扉16,18の上下に対向する端面16a,18aは平行に重なり、上部扉16に配設された感知部22と下部扉18に配設された被感知部24も上下方向に整列状態で対向する。両扉16,18に配設されたスイッチ要素が対向して臨むと、上部扉16の感知部22は、被感知部24であるマグネットの磁気を感知してドアスイッチ20はON状態となる。すなわち、前記冷気循環ファン50に運転命令を出し、収容室12内を冷気が循環すると共に、前記庫内灯は消灯状態に保持される。このとき、前記ドアスイッチ20の両要素22,24と同一端面16a,18aに配設された両磁石31,32は、上下方向に対向して互いに反発しあうが、両扉16,18に設けられたゴム磁石等の保持手段(図示せず)により該両扉16,18の閉成状態は維持される。また、例えば上部扉16を開放した際には、整列状態で対向していた前記感知部22および被感知部24は、該扉16の開放に伴って離間してドアスイッチ20がOFF状態となり、冷気循環ファン50の作動が停止され、開放された該扉16の開口部14から冷気が逃げるのを防止する。更に、前記庫内灯は点灯されて、収容室12内を明るくする。
【0015】
次に、図3の左側において上下に並設された扉16,18で示すように、上下の両扉16,18を開放した場合においては、上下に配設されて同極同士を対向する両磁石31,32が反発しあうことにより、上下の両扉16,18は重なり合った状態で維持されることがなく相互に離間する方向に回動する。すなわち、両扉16,18が開放した状態において、前記感知部22と被感知部24が整列的に対向する状態が維持されないので、両扉16,18が開放状態にあるにも拘わらず前記ドアスイッチ20がON状態となる誤作動を防止し得る。また、上下方向に並設した扉16,18の最大開放角度が異なるように設定されているので、両扉16,18は最大開放位置にてストッパ機構にて係止された時、重なり合った状態で保持されることがなく、ドアスイッチ20の誤作動を防止することができる。
【0016】
前記ドアスイッチ20にて冷気循環ファン50や庫内灯を制御する場合について説明したが、制御する機器は冷気循環ファン50や庫内灯に限定されず、その他の内部機器であってもよい。また、前記ドアスイッチ20は上部扉16に感知部22を配設し、下部扉18に被感知部24を配設する構成であるが、上部扉16に被感知部24を配設し、下部扉18に感知部22を配設する構成であってもよい。前記ドアスイッチ20の扉16,18に配設する位置は適宜に変更され、該ドアスイッチ20の位置に合わせて磁石31,32の位置は変更される。
【0017】
【発明の効果】
以上に説明した如く、本発明に係る貯蔵庫のドア装置によれば、上下に並設した扉の上下に対向する一方の端面に配設される感知部と、他方の端面に配設される被感知部とからなる内部機器の制御スイッチが付設される貯蔵庫において、両扉が開放した際に、前記感知部と被感知部とが上下に重なるのを規制手段により規制するよう構成したので、扉が開放しているにも拘わらず制御スイッチが扉の閉成状態を検知する誤作動を生ずるのを防止し得る。また、両扉の上下に対向する端面における前記感知部および被感知部の配設位置から離間する位置に、同極同士を上下に対向可能な一対の磁石を配設したことで、両扉の開放状態において、両磁石の反発作用により感知部と被感知部とが上下に重ならないよう両扉を相互に離間させることができ、前記制御スイッチの誤作動を防止することができる。更に、上下の扉の最大開放角度を異なるように設定したので、該両扉が最大限に開放された状態であっても、制御スイッチの誤作動を防止することができる。

As shown in FIG. 5, the magnets 31 and 32 are disposed on the same upper end surface 16a near the open end where the upper magnet 31 is separated from the sensing portion 22 of the upper door 16, and one end of the upper magnet 31 is It is embedded in foam insulation adjacent to the exterior material that defines the upper door 16. The lower magnet 32 is disposed on the upper end surface 18a of the lower door 18 in a state where both the upper and lower doors 16 and 18 are closed and aligned with the upper magnet 31 disposed on the upper door 16. . That is, the lower magnet 32 is embedded in the foamed heat insulating material with one end thereof adjacent to the upper end surface 18 a of the lower door 18. The magnets 31 and 32 are disposed so that the same poles can be opposed to each other up and down. When the doors 16 and 18 are opened, the resilient force of the magnets 31 and 32 causes the sensing unit 22 and the sensed unit 24 to move. The doors 16 and 18 are configured to move away from each other so that the doors do not overlap one another. The repulsive force of the magnets 31 and 32 is set to a value that does not hinder the holding of the doors 16 and 18 at the closed position by rubber magnets or the like.

Operation of the embodiment
Next, the operation of the storage door device according to the embodiment will be described. As shown in FIG. 2, the doors 16, 18 disposed vertically so as to close the respective openings 14 of the respective accommodation chambers 12 in the heat-insulating box body 10 are closed when the doors 16, 18 are closed. The upper and lower facing end surfaces 16a and 18a overlap in parallel, and the sensing unit 22 provided on the upper door 16 and the sensed unit 24 provided on the lower door 18 also face each other in a vertically aligned state. When the switch elements disposed on both doors 16 and 18 face each other, the sensing unit 22 of the upper door 16 senses the magnetism of the magnet that is the sensed unit 24 and the door switch 20 is turned on. That is, an operation command is issued to the cool air circulation fan 50, the cool air circulates in the storage chamber 12, and the interior lamp is kept in the off state. At this time, the two magnets 31, 32 disposed on the same end faces 16a, 18a as the two elements 22, 24 of the door switch 20 oppose each other in the vertical direction, but are provided on both doors 16, 18. The closed state of the doors 16 and 18 is maintained by a holding means (not shown) such as a rubber magnet or the like. Further, for example, when the upper door 16 is opened, the sensing unit 22 and the sensed unit 24 which face each other in the aligned state are separated with the opening of the door 16 and the door switch 20 is turned off, The operation of the cool air circulation fan 50 is stopped to prevent the cool air from escaping from the opening 14 of the opened door 16. Further, the interior light is turned on to brighten the interior of the accommodation room 12.
[0015]
Next, as shown by the doors 16 and 18 arranged vertically on the left side of FIG. 3, when the upper and lower doors 16 and 18 are opened, both doors arranged vertically and having the same pole facing each other are opened. When the magnets 31 and 32 repel each other, the upper and lower doors 16 and 18 rotate in a direction away from each other without being maintained in an overlapping state. That is, when the doors 16 and 18 are open, the state in which the sensing unit 22 and the sensed unit 24 face each other is not maintained, so that the doors 16 and 18 are open even though the doors 16 and 18 are open. A malfunction in which the switch 20 is turned on can be prevented. Also, since the maximum opening angles of the vertically arranged doors 16 and 18 are set to be different, when the doors 16 and 18 are locked by the stopper mechanism at the maximum opening position, they overlap each other. , The malfunction of the door switch 20 can be prevented.
[0016]
Although the case where the cool air circulation fan 50 and the interior light are controlled by the door switch 20 has been described, the devices to be controlled are not limited to the cool air circulation fan 50 and the interior light, and may be other internal devices. The door switch 20 has a configuration in which the sensing unit 22 is arranged on the upper door 16 and the sensed unit 24 is arranged on the lower door 18. A configuration in which the sensing unit 22 is provided on the door 18 may be employed. The positions of the door switches 20 disposed on the doors 16 and 18 are appropriately changed, and the positions of the magnets 31 and 32 are changed in accordance with the positions of the door switches 20.
[0017]
【The invention's effect】
As described above, according to the door device for a storage according to the present invention, the sensing unit provided on one end face of the doors arranged vertically and opposed to the upper and lower sides and the cover provided on the other end face are provided. In a storage provided with a control switch of an internal device including a sensing unit, when both doors are opened, the sensing unit and the sensed unit are configured to regulate the vertical overlap by the regulating means. It is possible to prevent the control switch from erroneously detecting the closed state of the door even though the door is open. In addition, by disposing a pair of magnets capable of vertically opposing the same poles at positions spaced apart from the arrangement positions of the sensing unit and the sensed unit on the end faces of the doors facing up and down, In the open state, the doors can be separated from each other by the repulsive action of the two magnets so that the sensing part and the sensed part do not overlap vertically, and malfunction of the control switch can be prevented. Furthermore, since the maximum opening angles of the upper and lower doors are set differently, it is possible to prevent the control switch from malfunctioning even when both doors are fully opened.
