Description

【０００１】
【発明の属する技術分野】
この発明は、ポットの化粧パネルの取付け構造に関するものである。
【０００２】
【従来の技術】
電気湯沸かし器等のポットにおいては、その胴部材前面に水位管窓を設ける一方、その水位管窓とその周辺の胴部材前面をカバーするパネル又はシートでなるカバー部材が装着され、そのカバー部材に設けた透明部から水位管窓を通して内部の水位管を見通せるようになっている（特許文献１）。前記の水位管窓は胴部材前面の中心又は中心から左右いずれか一方に片寄った位置に設けられ、その位置に合わせてカバー部材が装着される。そのカバー部材には水位表示が施され水位管と併せて水位を表示する機能を有するほか、適宜な着色等を施すことにより、胴部前面にデザイン的なアクセントを付与する機能を併せてもつものである。
【０００３】
一方、胴部材の前面を大きく開放し、その開放部分を通して部品の組立や修理などが行えるようにしたポットにおいては、その開放部を閉鎖するともに内部の水位管を見通せるようにした広幅の前面パネルを取付けることが行われる（特許文献２）。この前面パネルは、胴部材の開放部内側面に設けたガイド溝に下端側から差し込むとともに、その上端縁をノーズ部下面に突き当て、下端に設けた屈曲片を胴部材底面にビス止めすることにより取付けられる。

特開２００１−２４５７８９号公報（図１、図２参照）
【０００５】
【発明が解決しようとする課題】
前記のように胴部材前面に設けた広幅の前面パネルは、胴部材の前面開放部を閉塞する機能のほかに、透明部分を通して水位管を見通せるようになっており、またその表面が広いことから、従来のように水位窓近辺のみをカバーするカバー部材に比べ、施し得るデザインの自由度が大きいメリットがある。デザインの自由度を高く維持するためには前記の前面パネルは通常合成樹脂の成形品が用いられる。
【０００６】
しかし、前記の構造では前面パネルの背後を支持する手段がないため、使用者が故意に又は不注意で指先で前方から押すと容易に変形することがあり、また、外部からの荷重を加えない場合であっても熱変形等の内部応力により変形し易い問題考えられる。また、その前面パネルの上端縁はノーズ部下面に突き当てられるだけであるので、突き当て部分にすき間が生じ易い問題がある。また、その前面パネルの前面にインサート成形等によって印刷シートを一体化する方法をとった場合、印刷シートの上端が外部に露出することがあり、デザイン的な観点から問題があるものである。
【０００７】
そこで、この発明は幅の広い化粧パネルが十分に補強され、デザイン的にも優れたものとなる化粧パネルの取付け構造を提供することを課題とする。
【０００８】
【課題を解決するための手段】
前記の課題を解決するために、この発明は、ポットの胴部材前面に設けた水位管窓とその周囲の胴部材をカバーする範囲に化粧パネルを重ね、該化粧パネルを胴部材に結合一体化してなるポットの化粧パネル取付け構造において、前記化粧パネルは前記水位管窓の範囲を含み、かつポットの肩部材前部に設けたノーズ部の左右両端部までの幅又はその両端部を越える幅を有し、前記化粧パネルの背面は前記水位管窓の部分を除き前記胴部材に密着して結合一体化されている構成を採用した。
【０００９】
上記において、化粧パネルの幅は、胴部材に設けられた水位管窓を含むこと、及び少なくともノーズ部の最大幅と同一であることを条件とすることにより、従来の水位管近傍をカバーするカバー部材との幅の相違を明確にしている。また、化粧パネルの背面は前記水位管窓の部分を除き前記胴部材に密着して結合一体化した構成により、前述の従来のものと相違し、十分な強度が得られる。
【００１０】
また、前記化粧パネルはその背面に設けた係止爪を前記胴部材に設けた係合穴に挿入し係合することにより該胴部材に結合され、その化粧パネルの上縁部と胴部材の上縁部に前記ノーズ部のアンダーカバーの後端の形状に合致する切欠き凹部を設け、そのアンダーカバー後端面に下向きの嵌合溝を有する嵌合部を後方に突き出して設け、前記アンダーカバーの後端面に前記化粧パネルの切欠き凹部の前面を部分的に重ねるとともに化粧パネルと胴部材の切欠き凹部の一部を前記嵌合溝にその下方から係合することにより該化粧パネルの動きを規制した構成を採ることができる。
【００１１】
また、前記嵌合溝の化粧パネルと対向した位置にスリット又は下方に開放された凹部からなる係止部を設け、前記化粧パネルの切欠き凹部に設けた突片を該係止部に挿入した構成を採ることもできる。
【００１２】
前記化粧パネルを取付ける胴部材の前面部が、その幅方向の中心部分が凹入した湾曲面に形成され、前記化粧パネルに前記前面部に沿った湾曲面を設けた構成や、前記化粧パネルの背面に設けた係止爪のうち該化粧パネル下部中央に設けた係止爪は非ベンディング性の係止爪であり、その他はベンディング性の係止爪である構成を採ることもできる。
【００１３】
さらに、前記アンダーカバーの左右両側縁上端から後方に突き出して設けた突片を前記胴部材の切欠き凹部の左右の上端に係合させ、該突片を胴部材とその胴部材上に結合されたポットの肩部材とにより挟着し、その挟着により前記アンダーカバーの上下方向の動きを規制した構成、前記アンダーカバーの突片に、その部分を挟着する胴部材又は肩部材のいずれか一方に係合するスリットを設け、その係合により該アンダーカバーの左右方向及び前後方向の移動を規制した構成をとることができる。
【００１４】
【発明の実施の形態】
以下、この発明の実施の形態を添付図面に基づいて説明する。図１に示した電気ポットの本体１は、胴部材２とその上部に一体に設けられた肩部材３とからなり、肩部材３の後部に設けたヒンジ部４において蓋５が開閉自在かつ着脱可能に取付けられる。前記本体１の内部に内容器６が収納され、肩部材３の前部にノーズ部７が設けられる。ノーズ部７の上面に操作パネル８が取付けられるとともに、その下面にアンダーカバー９が取付けられ、そのアンダーカバー９に吐出口１０が設けられる。
【００１５】
図２に示したように、内容器６の上端つば部１１が肩部材３の内周縁に係合され、その内容器６の底面に固定した足金具１２がビス１３により胴部材２に取付けた底板１４に連結固定される。ビス１３の締め上げにより、胴部材２、肩部材３、内容器６、底板１４が一体化される。内容器６の底面に接続された通水パイプ１５の途中にポンプ１６が介在される。通水パイプ１５が内容器６の前面で立ち上がった部分が水位管１７（図５参照）となっている。水位管１７の上端部は安全弁ユニット１８を介して吐出管１９に接続され、その吐出管１９の先端が前記の吐出口１０に臨んでいる。
【００１６】
図３は前記の胴部材２、肩部材３を示すともに、胴部材２の前面に取付けられる化粧パネル２１、肩部材３の下面と胴部材２の前面上端縁に取付けられるアンダーカバー９、胴部材２の後面上端縁と肩部材３のヒンジ部４下部との間に介在されるヒンジ操作ユニット２３を示している。
【００１７】
胴部材２は、合成樹脂製であり全体として円筒形に形成され、前記のノーズ部７を前方、ヒンジ部４を後方とする位置関係に従えば、境界ははっきりしないが、胴部材２の全周は、前面部２４、左右の両側面部２５、２５及び後面部２６に分けられる。前面部２４は中央部が緩やかに凹入した湾曲面となっている。前面部２４の上端縁にほぼ湾曲面の幅に渡り長方形の切欠き凹部２７が形成される。この部分の前面には後述のようにアンダーカバー９の後端部が嵌合される。
【００１８】
前面部２４と左右両側面２５、２５の境界部分はアールをもって突き出した角部２８、２８が存在し、前方から見て右側の角部２８上に上下方向に長い水位管窓２９が設けられ、前記の水位管１７がその内方に配置される。
【００１９】
前記前面部２４から両方の角部２８、２８を越えて側面部２５、２５に渡る範囲は、化粧パネル２１の取付け面３１となっており、その境界に浅い段部３２を設けている。段部３２は、図３に示したように、角部２８、２８を越えた側面部２５、２５に形成された両側段部３２ａ、胴部材２の下端縁に沿って両側段部３２ａの下端間に形成された下縁段部３２ｂ、胴部材２の上端縁に沿って両側段部３２ａから前記切欠き凹部２７の左右両側辺間に形成された上縁段部３２ｃとからなる。上記の両側段部３２ａ、下縁段部３２ｂ、切欠き凹部２７に沿った取付け面３１にそれぞれ複数の係合穴３３が設けられる。
【００２０】
前記の化粧パネル２１は、図３に示したように、胴部材２の前面部２４の湾曲面に沿って凹入した湾曲部３４、その両側の角部３５，３５を介して側面部３６、３６を有し、湾曲部３４の上端縁にアンダーカバー９の後端が嵌合する長方形の切欠き凹部３７が形成される。この切欠き凹部３７は前記胴部２の切欠き凹部２７とほぼ合致する形状に形成される。また、化粧パネル２１の裏面には、胴部材２側の係合穴３３に合致する位置に係合爪３８が設けられる。このうち下端縁の中央部に設けられた係合爪３８Ａは、図６に示したように下向きコの字型に形成され、これに対向した相手の係合穴３３Ａも他の係合穴３３より大きく形成される。上記の係合爪３８Ａはベンディングすることなく係合穴３３Ａに係合されるが、他の係合爪３８は相手係合穴３３に対してベンディングにより係合される。このような非ベンディング性の係合爪３８Ａを設けるのは、化粧パネル２１の湾曲部３４と胴部材２側の前面部２４は湾曲していることによる。即ち、その係合爪３８Ａのみを係合穴３３Ａに対して先に係合し、その部分で回転させながら該化粧パネル２１を立ち上げ（図６の２点鎖線参照）、他の全ての係合爪３８をベンディングさせながら係合穴３３に係合させという組み立て手順をとる。
【００２１】
前記の化粧パネル２１の裏面には射出成形時のゲート痕３９があるが（図３参照）、これを受け入れる穴４１が胴部材２側に設けられる。また、化粧パネル２１の表面には、インモールド成形又はインサート成形等により印刷による装飾が施される。この印刷において、胴部材２の水位管窓２９に対応した部分には透明の窓部４２が形成される。
【００２２】
化粧パネル２１は、前述のように係合爪３８、３８Ａと、係合穴３３、３３Ａとの係合により胴部材２の取付け面３１に嵌合されるとともに、その外周辺が取付け面３１の段部３２に係合される。このうち両側段部３２ａ、３２ａは、図５（ａ）（ｂ）に示したように、アンダーカットになっており、そのアンダーカットの両側段部３２ａに嵌合するように化粧パネル２１の両側縁も鋭角の断面を有するように形成される。この両側段部３２ａに化粧パネル２１の両側縁が嵌合されることにより、化粧パネル２１の左右方向の移動が規制される。
【００２３】
次に、前記化粧パネル２１の上下方向及び前後方向の移動を規制する構造等について説明する。前記のようにして化粧パネル２１を胴部材２前面の取付け面３１に取付けると、胴部材２と化粧パネル２１の各上端縁に設けた切欠き凹部２７、３７が合致するが、その合致した部分にアンダーカバー９の後端部を嵌合させる。アンダーカバー９の後端部下縁部には、図４に示したように、下向きに開放された嵌合溝４０を有する逆Ｌ形断面の嵌合部４３が設けられる。その嵌合溝４０には、アンダーカバー９の後面に沿った左右方向のスリット４４が設けられ、そのスリット４４に化粧パネル２１の切欠き凹部２７に設けられた突片４５が下方から挿入される。後述のように、アンダーカバー９は肩部材３のノーズ部７に固定されるので、突片４５をスリット４４に嵌入することにより、化粧パネル２１の上下方向への移動が規制される。
【００２４】
また、前記の嵌合部４３において、化粧パネル２１の裏面側に重なった胴部材２側の切欠き凹部２７の上端部分が、化粧パネル２１の切欠き凹部３７の内側に接して嵌合溝４０に嵌入される（図７（ｂ）参照）。この構造により胴部材２と化粧パネル２１の各切欠き凹部２７、３７が前後に密着され相互に安定する。また、化粧パネル２１の切欠き凹部３７は前記の嵌合溝４０に差し込まれてアンダーカバー９内に入り、該切欠き凹部３７の他の部分もアンダーカバー９の内部に差し込まれる。これを現すために、図７（ａ）においてアンダーカバー９の後端面の位置を二点鎖線で示す。この二点鎖線の内側に両方の切欠き凹部２７、３７が存在することが分かる。前記嵌合部４３のスリット４４の上面に設けられたブリッジ部４６（図４参照）は、嵌合部４３を補強するために設けられたものである。
【００２５】
また、前記の切欠き凹部２７、３７の両端部において、アンダーカバー９の移動の規制が行われる。即ち、図４に示したように、アンダーカバー９の後端縁の左右両端部には、それぞれ水平面内で内方に突き出した突片４７、４７が設けられる。その突片４７は胴部材２の切欠き凹部２７の両端コーナー部４８、４８に載る。さらにその突片４７には、コーナー部４８に達している胴部材２の上端縁の嵌合リブ４９の端部が嵌合されるスリット５１が設けられる。突片４７が前記のコーナー部４８に載るとともに、そのスリット５１に胴部材２の嵌合リブ４９が嵌合され（図８（ａ）参照）、さらに肩部材３が胴部材２に結合一体化されることにより、その突片４７が胴部材２と肩部材３により挟持される（図８（ｂ）参照）。その挟持構造によりアンダーカバー９の上下方向の移動が規制されるとともに、嵌合リブ４９とスリット５１の嵌合によりアンダーカバー９の左右方向、前後方向の移動が規制される。
【００２６】
胴部材２と化粧パネル２１及びアンダーカバー９を以上のように組み合わせたのち、肩部材３との組み合わせが行われる。肩部材３には、図２、図３に示すように、その内周面に内容器６が嵌合されるほか、水位管１７、安全弁ユニット１８等が装着される。また後部下面にヒンジ操作ユニット２３が取付けられる。この状態で肩部材３が胴部材２の上部から組み合わされ、内容器６を胴部材２の内部に挿入するとともに、水位管１７等を所定位置に配置する。また、ノーズ部７の下端縁に設けた係合爪５２（図６参照）をアンダーカバー９の係合突片５３の穴に係合させる。前記の胴部材２、肩部材３、内容器６及び底板１４が足金具１２を介して結合一体化されることは、先に図２において説明したとおりである。
【００２７】
以上述べた実施形態においては、化粧パネル２１の形状が胴部材２の前面部２４の中心を基準として左右対称形に形成したものを示しているが、例えば、前面から見た化粧パネル２１の右側縁部は図３に示したように、水位管窓２９を越えた辺りに位置するが、左側縁部は左側の角部２８辺りまでとなるように形成した非対称形であってもよい。
【００２８】
また、胴部材２全体が円筒形に形成され、その前面部も前方に突き出た円弧面である場合や、水位管窓２９が前面部中心に設けられる場合もあるが、このような場合においても、化粧パネル２１は水位管窓２９の部分を含み、左右方向の幅は、ノーズ部７の幅以上に設定される。その程度の幅広に形成されることにより、化粧パネル２１のデザインの自由度が発揮される。
【００２９】
【発明の効果】
以上のように、この発明によれば、化粧パネルの幅は胴部材の前面部、場合によっては前面部を越えて左右両側面部に達する程度の幅の広いのものであり、デザインの自由度が高い利点がある。また、そのように広いものであっても、水位管窓の部分を除き、化粧パネルの裏面全体が胴部材の前面に密着して支持されるため、化粧パネルに外力が作用しても変形することがなく、また内部応力が発生しても胴部材により矯正され、長期にわたり美的効果を発揮することができる。また、その化粧パネルの上端縁はノーズ部のアンダーカバー内部に隠れるため、印刷面の上端部が露出することがなく、またアンダーカバーとの間にすき間が生じることもない。さらに、化粧パネルの取付けにビスを使用しないにもかかわらず、前記アンダーカバーによる化粧パネルと胴部材の切欠き凹部との嵌合構造等により、化粧パネルをがたつき無く取付けることができる。

BACKGROUND OF THE INVENTION
The present invention relates to a mounting structure for a decorative panel of a pot.
[0002]
[Prior art]
In pots such as electric water heaters, a water level tube window is provided on the front surface of the body member, and a cover member made of a panel or sheet covering the water level tube window and the front surface of the surrounding body member is mounted on the cover member. The internal water level pipe can be seen from the transparent part through the water level pipe window (Patent Document 1).

【The invention's effect】
As described above, according to the present invention, the width of the decorative panel is wide enough to reach the left and right side portions beyond the front portion of the body member, and in some cases, the front portion. There are high advantages. Moreover, even if it is so wide, since the entire back surface of the decorative panel is supported in close contact with the front surface of the body member except for the water level tube window portion, it is deformed even if an external force acts on the decorative panel. Even if an internal stress occurs, it is corrected by the body member, and an aesthetic effect can be exhibited over a long period of time. Further, since the upper edge of the decorative panel is hidden inside the under cover of the nose portion, the upper end portion of the printing surface is not exposed and there is no gap between the under cover and the under cover. Further, the decorative panel can be mounted without rattling due to the fitting structure of the decorative panel by the under cover and the notch recess of the body member, etc., although screws are not used for mounting the decorative panel.
