【発明の属する技術分野】
この発明は、可燃性冷媒を用いた冷蔵庫に関する。
【0002】
【従来の技術】
一般に冷蔵庫は、冷蔵庫本体と開閉扉とから成り、開閉扉を開けることで、食品等の出し入れが行なえるようになっている。
【0003】
開閉扉は、ドアヒンジを支点として回動自在に支持され、閉めた時に冷蔵庫本体と接触し合う接触当り面はゴム製のシール部材によって気密状態が確保され、冷蔵庫本体とは電気的に導通のない独立した構造となっている。
【0004】
【発明が解決しようとする課題】
開閉扉は、冷蔵庫本体に比べて表面積が小さく、しかも、独立していることもあって、静電気が蓄積され易く、開閉扉の開閉時にそれが静電気放電となって現れることがある。
【0005】
このような場合、冷蔵庫の冷媒に、例えば、地球温暖化の要因となる二酸化炭素を排出しない可燃性冷媒を用いた冷蔵庫において、何等かの原因で冷媒漏れがあった時、漏れた冷媒に引火することが想定される。
【0006】
そこで、この発明は、静電気による静電気放電の発生を抑えた冷蔵庫を提供することを目的としている。
【0007】
【課題を解決するための手段】
前記目的を達成するために、この発明の請求項1にあっては、冷凍サイクルを構成する冷媒に可燃性冷媒を用いた冷蔵庫において、冷蔵庫本体の金属部と開閉扉の金属部とを一定範囲の抵抗値を有する導電部材によって電気的に接続連通する一方、前記導電部材は、冷蔵庫本体に対して回動自在に開閉扉を支持するドアヒンジと、ドアヒンジのヒンジピンと接触し合う開閉扉の金属部から延長されたばね板材とで構成されていることを特徴とする。
【0008】
これにより、静電気は一定範囲の抵抗値を有する導電部材によって、いずれか一方に高く蓄積されることなく同電位に保たれる結果、開閉扉の開閉時に静電気放電の発生が抑えられ、可燃性冷媒が万一漏れた場合であっても安全が確保される。しかも、開閉扉の開閉動作に何等支障を与えることなく、冷蔵庫本体と開閉扉との電気的な接続連通状態が確実に得られる
【0017】
また、この発明の請求項2によれば、冷凍サイクルを構成する冷媒に可燃性冷媒を用いた冷蔵庫において、冷蔵庫本体の金属部と開閉扉の金属部とを一定範囲の抵抗値を有する導電部材によって電気的に接続連通する一方、前記導電部材を、冷蔵庫本体と開閉扉との接触当り面をシールするシール部材で構成することを特徴とする。
【0018】
これにより、導電部材を新たに設ける必要がなくなるため、組付性の面で大変好ましいものとなる。
【0019】
また、この発明の請求項3によれば、開閉扉の塗装に、一定範囲の抵抗値を有する導電性塗装材料を用いることを特徴とする。
【0020】
これにより、開閉扉の塗料に導電性塗料を用いることで、全領域にわたって電気的な確実な導通状態が得られる。
【0021】
また、この発明の請求項4によれば、冷凍サイクルを構成する冷媒に可燃性冷媒を用いた冷蔵庫において、冷蔵庫本体の金属部と開閉扉の金属部とを一定範囲の抵抗値を有する導電部材によって電気的に接続連通する一方、前記導電部材を、冷蔵庫本体に設けられる庫内部品、または、その表面材料とすることを特徴とする。
【0022】
これにより、庫内に静電気が蓄積されることがなくなる。
【0023】
また、この発明の請求項5によれば、冷凍サイクルを構成する冷媒に可燃性冷媒を用いた冷蔵庫において、冷蔵庫本体の金属部と開閉扉の金属部とを一定範囲の抵抗値を有する導電部材によって電気的に接続連通する一方、前記導電部材を、開閉扉を閉めた時に接触し、冷蔵庫本体と開閉扉との電気的な接続を図る接触手段とすることを特徴とする。
【0024】
これにより、例えば、開閉扉を全閉位置でストップさせるストッパ部材が導電部材となるため、導電部材を新たに設ける必要がなくなり、組付性の面で大変好ましいものとなる。また、開閉扉を閉めることで冷蔵庫本体と開閉扉とは必ず同電位となり、静電気放電の発生を抑えられる。
【0025】
【発明の実施の形態】
以下、図1と図2の図面を参照しながらこの発明の第1の実施形態について具体的に説明する。
【0026】
図1は冷蔵庫1の斜視図を示しており、冷凍サイクルを構成する冷媒に可燃性冷媒を用いている。冷蔵庫1は上方から冷蔵室3、野菜室5、冷凍室(図示していない)となっていて、冷蔵室3の開閉扉7は、開閉用の取手9を有し、ドアヒンジ11を支点として回動する回動タイプとなっている。
【0027】
野菜室5の開閉扉13は、図7に示すように左右の支持アーム15に設けられたローラ17が庫内に固定支持された左右のガイドレール19に沿って走行することで開閉する引出しタイプとなっている。
【0028】
冷蔵室用の開閉扉7のドアヒンジ11は、電気を通す金属性の材料で作られていて、一方はビスねじ23によって鋼板で作られた金属部となる冷蔵庫本体21の上面パネルに電気的に接続し合う状態で固定支持されている。ドアヒンジ11の他方はヒンジピン11aとなっていて、開閉扉7の上端部に設けられた合成樹脂性の扉キャップ25に対して回動自在に嵌合支持されている。
【0029】
ドアヒンジ11と開閉扉7とは、例えば、100MΩ以下となる一定範囲の抵抗値(以下同じ)を備えた導電部材27となる電線29を介して電気的に接続連通している。これにより、一定範囲の抵抗値によって静電気容量が多くなるような所であっても、一気に静電気が放出することがなくなり、火花放電が抑えられるようになっている。この場合、静電気容量の溜りにくい場所にあっては抵抗値を限りなくゼロに近い値のものを用いてもよい。
【0030】
導電部材27となる電線29の一方は、ドアヒンジ11を止める一方のビスねじ23を利用して直接ドアヒンジ11に固定支持されている。他方は、ヒンジピン11aに設けられた貫通孔を介して金属部となる鋼板で作られた開閉扉7に溶接等の手段により溶着され、冷蔵庫本体21と開閉扉7との電気的な接続状態が確保されると共に、電線29及びドアヒンジ11はヒンジカバー31によりカバーされている。
【0031】
開閉扉7の取手9は、全領域にわたって一定範囲の抵抗値を有する導電性材料33が設けられている。この場合、導電性材料33を取手9の一部領域に設けるようにしてもよい。
【0032】
このように構成された冷蔵庫1によれば、いずれか一方に静電気が蓄積されることなく同電位に保たれる結果、開閉扉7の開閉時に静電気放電が発生することはなく、万一冷媒漏れが起きても安全が確保される。
【0033】
一方、帯電した人が開閉扉7の取手9に手をかけた時に、一定範囲の抵抗値を有する導電性材料33によって静電気放電を起こすことなく冷蔵庫1と同電位となるため、万一冷媒が庫外へ漏れた場合でもその冷媒と引火する恐れはなく安全が確保される。
【0034】
図3は冷蔵庫本体21と開閉扉7とを電気的な接続を図る導電部材27の第2の実施形態を示したものである。
【0035】
即ち、ドアヒンジ11のヒンジピン11aを、一定範囲の抵抗値を備えた開閉扉7の金属部から立上がる金属性の軸受部材35に対して回転自在に嵌挿支持し、前記ドアヒンジ11を介して直接冷蔵庫本体21と開閉扉7との電気的な接続連通を図る手段としたものである。
【0036】
この場合、軸受部材35を用いずに、扉キャップ25を導電性材料によって構成する手段としてもよい。
【0037】
なお、他の構成要素は第1の実施形態と同一のため同一符号を付して詳細な説明を省略する。
【0038】
したがって、この第2の実施形態によれば、第1の実施形態の効果に加えて、新たに導電部材27を設けなくともよいため組付性、コストの面において大変好ましいものとなる。
【0039】
図4と図5は冷蔵庫本体21と開閉扉7とを電気的な接続を図る導電部材27の第3の実施形態を示したものである。
【0040】
即ち、ドアヒンジ11のヒンジピン11aを、扉キャップ25に回転自在に嵌挿支持し、そのヒンジピン11aに開閉扉7の金属部から立上がる一定範囲の抵抗値を備えたばね板材37を接触させて冷蔵庫本体21と開閉扉7の電気的な導通を図る手段としたものである。
【0041】
なお、他の構成要素は、第1の実施形態と同一のため同一符号を付して詳細な説明を省略する。
【0042】
したがって、この第3の実施形態によれば、第1の実施形態の効果に加えて、開閉扉7の開閉動作に何等支障を与えることなく、冷蔵庫本体21と開閉扉7との電気的な接続連通状態が確実に得られる。
【0043】
図6は冷蔵庫本体21と開閉扉7とを電気的な接続を図る導電部材27の第4の実施形態を示したものである。
【0044】
即ち、全閉時に冷蔵庫本体21の開口部周りと弾接し合う開閉扉7,13のシール部材41の一部領域にわたって、一定範囲の抵抗値を備えた導電材料39により導電部材27を設けるようにするものである。
【0045】
導電部材27は開閉扉7の金属部と接続し合う一方、全閉時に冷蔵庫本体21の開口部周りと弾接し合うことで冷蔵庫本体21と開閉扉7とが電気的に接続連通し合う構造となっている。
【0046】
この場合、冷蔵庫本体21の開口部周りがプラスチック等の合成樹脂材によって成形されている場合には、その当り面に導電部材27と接触し合う導電材料による塗膜43領域を設けるようにすることが望ましい。
【0047】
なお、他の構成要素は第1の実施形態と同一のため同一符号を付して詳細な説明を省略する。
【0048】
したがって、この第4の実施形態によれば、第1の実施形態の効果に加えて、導電部材27を新たに設ける必要がなくなるため、組付性の面で大変好ましいものとなる。
【0049】
図7は冷蔵庫本体21と前記した引出しタイプの開閉扉13とを電気的な接続を図る導電部材27の第5の実施形態を示したものである。
【0050】
この第5の実施形態は庫内部品を利用して電気的な接続を図るようにしたものである。具体的には、引出しタイプの開閉扉13にビス45によって固定支持された収納庫を支持する左右の支持ステー15を金属性の材料で形成する一方、その支持ステー15がガイドレール19に沿って一杯に押込まれた時に、冷蔵庫本体21の金属部に固定支持されたばね板接点47が支持ステー15の上端縁とスライド自在に接触し合うことで、冷蔵庫本体21及び庫内と開閉扉13との電気的な接続が得られる構造となっている。
【0051】
なお、他の構成要素は第1の実施形態と同一のため同一符号を付して詳細な説明を省略する。
【0052】
したがって、この第5の実施形態によれば、庫内に静電気が蓄積されることがなくなる。
【0053】
図8は冷蔵庫本体21と開閉扉7とを電気的に接続を図る導電部材27の第6の実施形態を示したものである。
【0054】
即ち、冷蔵庫1には、開閉扉7を全閉位置でストップさせる接触手段となるストッパ49が冷蔵庫本体21に、そのストッパ49と当接し合うストッパ凹部51が開閉扉7にそれぞれ設けられているが、そのストッパ49とストッパ凹部51とを金属性の材料で形成するものである。これにより、固定ビス53に固定支持されたストッパ49及び冷蔵庫本体21と、ストッパ凹部51及び開閉扉7とはそれぞれ電気的な導通状態が得られるようになる。
【0055】
なお、他の構成要素は第1の実施形態と同一のため同一符号を付して詳細な説明を省略する。

BACKGROUND OF THE INVENTION
The present invention relates to a refrigerator using a flammable refrigerant.
[0002]
[Prior art]
Generally, a refrigerator includes a refrigerator main body and an opening / closing door, and food and the like can be taken in and out by opening the opening / closing door.
[0003]
The open / close door is pivotally supported using a door hinge as a fulcrum, and the contact surface that comes into contact with the refrigerator body when closed is secured by a rubber seal member and is not electrically connected to the refrigerator body. It has an independent structure.
[0004]
[Problems to be solved by the invention]
The open / close door has a smaller surface area than the refrigerator main body and is independent, and static electricity is likely to be accumulated, which may appear as electrostatic discharge when the open / close door is opened / closed.
[0005]
In such a case, for example, in a refrigerator that uses a flammable refrigerant that does not emit carbon dioxide, which is a cause of global warming, if the refrigerant leaks for any reason, the refrigerant ignites. It is assumed that
[0006]
Accordingly, an object of the present invention is to provide a refrigerator in which the occurrence of electrostatic discharge due to static electricity is suppressed.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, according to claim 1 of the present invention, in a refrigerator using a flammable refrigerant as a refrigerant constituting a refrigeration cycle, the metal part of the refrigerator main body and the metal part of the opening / closing door are within a certain range. The conductive member is electrically connected and communicated by a conductive member having a resistance value of the metal door, and the conductive member is a door hinge that supports the door in a rotatable manner with respect to the refrigerator body, and a metal part of the door that contacts the hinge pin of the door hinge. It is characterized by being comprised by the spring-plate material extended from .
[0008]
As a result, the static electricity is maintained at the same potential without being accumulated in either one by a conductive member having a resistance value within a certain range. As a result, the occurrence of electrostatic discharge is suppressed when the door is opened and closed, and a flammable refrigerant. Even if a leak occurs, safety is ensured. And the electrical connection communication state of a refrigerator main body and an opening / closing door is obtained reliably, without giving any trouble to the opening / closing operation | movement of an opening / closing door .
[0017]
According to claim 2 of the present invention, in the refrigerator using a combustible refrigerant as a refrigerant constituting the refrigeration cycle, the conductive member having a resistance value within a certain range between the metal portion of the refrigerator main body and the metal portion of the door. The conductive member is configured by a seal member that seals a contact surface between the refrigerator main body and the open / close door.
[0018]
This eliminates the need to newly provide a conductive member, which is very preferable in terms of assembly.
[0019]
According to a third aspect of the present invention, a conductive coating material having a resistance value within a certain range is used for coating of the open / close door.
[0020]
Thereby, an electrically reliable conductive state is obtained over the entire region by using a conductive paint for the paint of the door.

Thereby, static electricity is not accumulated in the cabinet.
[0023]
According to claim 5 of the present invention, in the refrigerator using a combustible refrigerant as a refrigerant constituting the refrigeration cycle, the conductive member having a resistance value within a certain range between the metal portion of the refrigerator main body and the metal portion of the door. The conductive member is in contact with the door when the door is closed, and serves as a contact means for making an electrical connection between the refrigerator body and the door.
[0024]
Thereby, for example, since the stopper member that stops the open / close door at the fully closed position becomes a conductive member, there is no need to newly provide a conductive member, which is very preferable in terms of assembly. In addition, by closing the door, the refrigerator body and the door always have the same potential, and the occurrence of electrostatic discharge can be suppressed.
