Description

【0001】
【発明の属する技術分野】
この発明は、給湯器にリモコンコードを接続する際に使用する給湯器のコード接続装置に関する。
【0002】
【従来の技術】
給湯器の設置工事に際し給湯器にリモコンコードを接続する場合、従来一般には、たとえば、図9に例示されているように、給湯器D′のフロントカバー1a′を取り外したケーシング1′の底面壁2′に備えた電線管接続部B′からリモコンコード8′をケーシング1′内に引き込んでケーシング1′内の一側に備えた端子接続部5′に接続してコードクランプ5a′で位置決め保持し、その後、フロントカバー1a′を再び取り付けるといった作業を要していた。
【0003】
こうしたコード接続装置では作業性がよくないことから、最近フロントカバーを取り外すことなくリモコンコードが接続できる技術が提案されている。すなわち、給湯器にリモコンコードを接続するにあたり、接続端子台をケーシング外に露出させ、この露出した接続端子台にリモコンコードを接続した後、接続端子台を再びケーシング内に収納するものである。
上記露出手段としては、一側ヒンジ部を支点として下方へ90度回動させることにより接続端子台をケーシング外に露出できるようにした構造のもの(たとえば、特開平9−199874号公報の図6、図7参照)又は接続端子台を下方へ直線的に引っ張り出して接続端子台をケーシング外に露出させる構造のもの(たとえば、特開平8−167437号公報の図18、図19参照)等がある。
【0004】
【発明が解決しようとする課題】
しかしながら、上記従来の技術では、ケーシング外に露出された接続端子台に安定性がないので、接続作業時に接続端子台が動いてしまい作業がやりにくく、また、上記従来技術以外の場合でも接続端子台の接続部が壁で覆われているために接続作業がしずらいこともあって作業能率が著しく低下するという問題点があり、さらには、電線管接続部は接続端子台と一体で固定的となっているので、電線管の取付けに際してはユニオンねじを電線管接続部と電線管との間に設けるか、電線管の方を回転して螺着しなければならないことからその取付けにはコストアップもしくは困難性がともない、また、電線管を取付けない場合は電線管接続部から内部の端子接続部へ飛び跳ね侵入する雨水による短絡、腐蝕等のトラブルも多く発生するという問題点があった。
【0005】
この発明の給湯器のコード接続装置は上記課題を解決し、接続端子台をケーシング外に設置し、この接続端子台に対し別体の電線管接続体を脱着可能に設けて端子及び電線管の接続が迅速、確実に、しかも、簡易に行えるようにするとともに、雨水によるトラブルへの配慮も十分とした給湯器のコード接続装置の提供を目的としている。
【0006】
【課題を解決するための手段】
上記課題を解決するこの発明の請求項1の給湯器のコード接続装置は、
給湯器のケーシングの外部に固定して配線コードを接続配線する接続端子台と、
上記接続端子台を覆って接続端子台の保護カバーを兼備する電線管接続体とを別体に備え、
上記ケーシングに対し上記電線管接続体を脱着可能に備え給湯器のコード接続装置であって
上記接続端子台は、端子接続部とコード挿通部とを区画し、かつ配線コードを挿通部側から端子接続部側へ通す凹溝を設けた仕切壁を備え、
前記仕切壁で区画された端子接続部側において配線コードの端子を接続端子部に接続しうることを要旨とする。
【0008】
上記課題を解決するこの発明の請求項の給湯器のコード接続装置は、上記請求項1の給湯器のコード接続装置において、
上記凹溝は、仕切壁の両側端部に1または複数箇所設けられ、配線コードを挟入保持することを要旨とする。
【0009】
上記課題を解決するこの発明の請求項の給湯器のコード接続装置は、上記請求項1または2の給湯器のコード接続装置において、
上記接続端子台の端子接続部を斜状に備えたことを要旨とする。
【0010】
上記構成を有するこの発明の請求項1記載の給湯器のコード接続装置は、給湯器のケーシングの外部に固定される接続端子台と該接続端子台の保護カバーを兼備する電線管接続体とを別体に設けて、接続端子台に対し電線管接続体を脱着自由としたから、接続端子台に対するコードの接続作業が迅速、確実に、しかも、簡易に行えるとともに、電線管接続体に対する電線管の接続も電線管接続体を回転して螺着できるから、その取付けも容易に行いうる。この結果、作業性は向上し、作業能率も倍加する。
【0011】
上記構成を有するこの発明の給湯器のコード接続装置は、接続端子台の端子接続部とコード挿通部とが仕切壁で区画されいるので、端子接続部へ雨水が電線管接続部から飛び跳ね侵入することはない。この結果、雨水による端子接続部の短絡、腐蝕等の弊害は生じない。
【0012】
上記構成を有するこの発明の請求項記載の給湯器のコード接続装置は、凹溝は、仕切壁の両側端部に1または複数箇所設けられ、配線コードが挟入保持できるので、この凹溝に配線コードを嵌め込んで保持することでコード端子部に負荷をかけることがない。この結果、従来のコードクランプで止めるものに比べ作業性は著しく向上しクランプ用部品も不要となる。
【0013】
上記構成を有するこの発明の請求項記載の給湯器のコード接続装置は、接続端子台の端子接続部を斜状に設けたので、たとえば、高層集合住宅のパイプシャフト扉内設置の場合に取付けボックスを用いると、そのボックスが邪魔になってネジ締めができなくなるが、取付けボックスがあってもドライバー等の締付け工具によるネジ締めが支障なく行える。この結果、端子接続部に対するコードの接続作業がどのような設置条件に対しても的確、かつ、容易に行いうる。
【0014】
【発明の実施の形態】
以上説明したこの発明の構成、作用を一層明らかにするために、以下にこの発明の給湯器のコード接続装置の好適な実施の形態の一例について図面を参照して詳細に説明する。

【0017】
Bは上記接続端子台Aを覆って接続端子台Aの保護カバーを兼備する電線管接続体で、上記接続端子台Aとは別体に形成され、下部一側寄りに電線管16を接続するための接続螺管17を有し、その上部には上記接続端子台Aを覆う箱体18を備え、この箱体18の一側下部に上記接続端子台Aのネジ孔12に適合するネジ挿通孔19を備え、箱体18の上端一側には上記ケーシング1の底面壁2に起立状に備えた引掛片20に引掛けて位置決め支持する支持突部21を一体に備えた構成となっている。なお、上記支持突部21はケーシング1の底面壁2に穿った挿通孔22に下方から挿通して引掛片20に引掛けるものである。
【0018】
そこで、ケーシング1の底面壁2に予め固定配線された接続端子台Aに対し上記電線管接続体Bを下方から被せ支持突部21を引掛片20に引掛けて電線管接続体Bをケーシング1の底面壁2に上縁のフランジ部23を介して押し当てネジ挿通孔19から止めネジ24を挿入してネジ孔12に螺合し締めつければ、接続端子台Aに対する電線管接続体Bの取付けが行え、止めネジ24を外せば電線管接続体Bの取り外しが行えるものである。なお、上記電線管16は可撓体で形成され屈曲自由となっている。この電線管16を上記電線管接続体Bに接続するときは、電線管接続体Bを回転して螺着接続するものである。
【0019】
上記構成において、給湯器Dのケーシング1の底面壁2に止めネジ3で固定され下方に露出している接続端子台Aの端子接続部5にバーコンに接続されたリード線9とリモコンコード8とを接続端子13、14を介して締付けビス15により締めつけ接続した後、リモコンコード8は一方の凹溝10に、リード線9は他方の凹溝11にそれぞれ嵌めつけて挟入保持し、次いで、電線管接続体Bを上記接続端子台Aに被せるように取付ければ、コード配線工事は完了するものである。図中25電源コードで、電線管接続体Bと接続端子台A内を素通りして配線される。

【0025】
この発明の請求項記載の給湯器のコード接続装置によれば、凹溝は、仕切壁の両側端部に1または複数箇所設けられ、配線コードが挟入保持できるので、この凹溝に配線コードを嵌め込んで保持することでコード端子部に負荷をかけることはない。したがって、従来のコードクランプで止めるものに比べ作業性は向上しクランプ用部品も不要なためコストダウンできる。また、接続端子台に対する電線管接続体の取付け時にリード線を損傷することもない。
【0026】
この発明の請求項記載の給湯器のコード接続装置によれば、接続端子台の端子接続部を斜状に設けたので、たとえば、給湯器を高層集合住宅のパイプシャフト扉内設置する場合でもドライバー等の締付け工具によるネジ締めが支障なく行える利便がある。

The remote control cord 8 'is drawn into the casing 1' from the conduit connecting portion B 'provided at 2', and connected to the terminal connecting portion 5 'provided on one side of the casing 1' and positioned and held by the cord clamp 5a '. After that, it is necessary to reattach the front cover 1a '.
[0003]
Since such a cord connection device is not easy to work with, a technology that can connect a remote control cord without removing the front cover has recently been proposed. That is, when connecting the remote control cord to the water heater, the connection terminal block is exposed outside the casing, the remote control cord is connected to the exposed connection terminal block, and then the connection terminal block is stored in the casing again.
The exposure means has a structure in which the connection terminal block can be exposed to the outside of the casing by rotating 90 degrees downward with the one side hinge portion as a fulcrum (for example, FIG. 6 of JP-A-9-199874). 7), or a structure in which the connection terminal block is linearly pulled downward to expose the connection terminal block outside the casing (for example, see FIGS. 18 and 19 of JP-A-8-167437). is there.
[0004]
[Problems to be solved by the invention]
However, in the above conventional technique, since the connection terminal block exposed outside the casing is not stable, the connection terminal block moves during the connection work, and the work is difficult to perform. Since the connection part of the base is covered with a wall, the connection work is difficult, and there is a problem that the work efficiency is remarkably lowered. Furthermore, the conduit connection part is fixed integrally with the connection terminal block. Therefore, when installing the conduit, a union screw must be installed between the conduit connection part and the conduit, or the conduit must be rotated and screwed. There is an increase in cost or difficulty, and if a conduit is not installed, troubles such as short circuit and corrosion due to rainwater jumping from the conduit connection to the internal terminal connection will occur. There was a problem point.
[0005]
The cord connection device for a water heater of the present invention solves the above-mentioned problems, and the connection terminal block is installed outside the casing, and a separate conduit connection body is detachably attached to the connection terminal block so that the terminal and the conduit tube The purpose of the present invention is to provide a cord connection device for a water heater that can be connected quickly, reliably and simply, and has sufficient consideration for trouble caused by rainwater.
