【発明の属する技術分野】
本発明は、外蓋の下端面に内鍋の上面を覆うように着脱自在に設けた内蓋ユニット部材を有する炊飯器に関するものである。
【0002】
【従来の技術】
従来、この種の炊飯器は、図8および図9に示すように構成していた。以下、その構成について説明する。
【0003】
図8に示すように、炊飯器本体53は、ヒンジ部51と係止部52とを設け、炊飯器本体53の上面開口部を覆う外蓋54の一端をヒンジ部51で回動自在とし、他端を係支部52で係止可能としている。この炊飯器本体53の内部に内鍋55を着脱自在に収納している。外蓋54の下方には、内鍋55の上部をシールする蓋パッキン62を具備する内蓋ユニット部材56を着脱自在に装着している。
【0004】
また、内蓋ユニット部材56の先端部に、蓋閉時に係止部52と係合する蓋係合部57を一体に設け、外蓋54の前部下方には蓋係合部57を保持する保持穴58を設けている。ここで、内蓋ユニット部材56の蓋係合部57と外蓋54の保持穴58は同形状に構成している。
【0005】
また、内蓋ユニット部材56の外周2箇所には、図9に示すように、内蓋ユニット部材56の着脱操作時に使用するリブ状のつまみ部59を有し、つまみ部59には、取付時に外蓋54に設けた内蓋ユニット部材係部60と保持係合する引掛けつめ61を一体に形成している。
【0006】
内蓋ユニット部材56をセットするときは、外蓋54の保持穴58に蓋係合部57を挿入した後、つまみ部59を押し込み、引掛けつめ61を係合させる。また、取り外すときは、リブ状のつまみ部59を引掛けつめ61が開放される位置まで内側に倒すことにより取り外すよう構成している。
【0007】
【発明が解決しようとする課題】
しかしながら、このような従来のような構成では、手入れした内蓋ユニット部材56を外蓋54にセットする際に、内蓋ユニット部材56の蓋係合部57と外蓋54の保持穴58とを同形状で構成しているため、ある一定以上の力を加え、こじたようなセットを行なうと、内蓋ユニット部材56の表裏の逆セットができてしまう。
【0008】
このために、内蓋ユニット部材56の蓋係合部57に変形が生じたり、内蓋ユニット部材56自体が変形してしまい、内蓋ユニット部材56と蓋パッキン62のシール性が確保できなくなり、炊飯中に発生した内鍋55内の蒸気がもれてしまうような問題を有していた。
【0009】
本発明は上記従来の課題を解決するもので、着脱自在の内蓋ユニット部材の外蓋へのセットの方向を一方向に規制し、表裏逆セットを防止することを目的としている。
【0010】
【課題を解決するための手段】
本発明は上記目的を達成するために、内鍋を収納する炊飯器本体の上面開口部を、一端を炊飯器本体に設けたヒンジ部で回動自在とした外蓋で覆い、外蓋の下端面に内鍋の上面を覆うように内鍋を密閉し得る鍋パッキンを有する内蓋ユニット部材を着脱自在に設け、前記外蓋は台形の保持穴を有し、かつ、前記内蓋ユニット部材は、一端に蓋係合部を突設するとともに他端に外蓋に設けた保持爪に係合する係止片を配設し、台形の蓋係合部を外蓋に設けた保持穴に内方より挿入し、係止片を保持爪に係合して外蓋に装着可能とし、外蓋の保持穴と内蓋ユニット部材の蓋係合部とで内蓋ユニット部材の表裏逆セットを防止するよう構成したものである。
【0011】
これにより、手入れした内蓋ユニット部材を外蓋にセットする際に、消費者が確実にある一定方向のセットを行うことができ、表裏逆セットを未然に防ぐことができる。
【0012】
【発明の実施の形態】
請求項に記載の発明は、内鍋を収納する炊飯器本体と、前記炊飯器本体の上面開口部を覆い一端を炊飯器本体に設けたヒンジ部で回動自在とした外蓋と、前記外蓋の下端面に前記内鍋の上面を覆うように着脱自在に設け内鍋を密閉し得る鍋パッキンを有する内蓋ユニット部材とを備え、前記外蓋は台形の保持穴を有し、かつ、前記内蓋ユニット部材は、一端に蓋係合部を突設するとともに他端に外蓋に設けた保持爪に係合する係止片を配設し、台形の前記蓋係合部を前記外蓋に設けた保持穴に内方より挿入し、前記係止片を前記保持爪に係合して前記外蓋に装着可能とし、前記外蓋の保持穴と内蓋ユニット部材の蓋係合部とで内蓋ユニット部材の表裏逆セットを防止するよう構成したものであり、手入れした内蓋ユニット部材を外蓋にセットする際に、消費者が確実にある一定方向のセットを行うことができ、表裏逆セットを未然に防ぐことができるとともに、部品点数を削減し、分解性を向上することができる。
【0013】
【実施例】
以下、本発明の実施例について、図面を参照しながら説明する。
【0014】
(実施例1)
図1に示すように、炊飯器本体3は、ヒンジ部1と係止部2とを設け、炊飯器本体3の上面開口部を覆う外蓋4の一端をヒンジ部1で回動自在とし、他端を係支部2で係止可能としている。この炊飯器本体3の内部に内鍋5を着脱自在に収納している。外蓋4の下方には、内蓋7に、内鍋5の上部をシールする蓋パッキン6を具備する内蓋ユニット部材8を着脱自在に装着している。
【0015】
また、内蓋ユニット部材8の先端部に、蓋閉時に係止部2と係合する蓋係合部9を一体に設け、外蓋4の前部下方には蓋係合部9を保持する保持穴10を配設している。
【0016】

【0017】
これにより、保持爪11やつまみ部12の成形時の反り、変形、経年変化による寸法変化を容易に吸収し、安定した着脱力を実現することができる。
【0018】
また、内蓋ユニット部材8を取り外すときには、つまみ部12を直接変形させる方式と異なり、ばね14により必要最低限の力で付勢されている係止片13を押し込むだけで容易に取り外すことができ、また、内蓋ユニット部材8を取り付けるときには、不安定な樹脂のたわみを利用する構成とは異なり、ばね14の付勢力により、カチッとした確実な取付感を得ることができ、着脱操作性を著しく向上することができるとともに、製品の品位品格向上に寄与することができる。
【0019】
つぎに、保持穴10に内蓋ユニット部材8の蓋係合部9を挿入し、内蓋ユニット部材8を外蓋4に取り付ける場合について説明する。
【0020】
保持穴10は、図3に示すように、外蓋4の前方下方に配設している。この保持穴10に、内蓋ユニット部材8の蓋係合部9を矢印方向に挿入して、保持穴10により、内蓋ユニット部材8を保持する。

【0022】
これにより、手入れした内蓋ユニット部材8を外蓋4にセットする際に、消費者が確実にある一定方向のセットを行うことができ、表裏逆セットを未然に防ぐことができる。
【0023】
また、上述のような構成ならば、構成の簡素化が可能となり、部品点数の削減と製品の組み立てと分解性を向上することができる。
【0024】
(実施例2)
図5に示すように、保持穴10aは、外蓋4aの前方下方に配設し、この保持穴10aに、内蓋ユニット部材8aの蓋係合部9aを矢印方向に挿入して、保持穴10aにより、内蓋ユニット部材8aを保持する。
【0025】
ここで、外蓋4aの保持穴10aと内蓋ユニット部材8aの蓋係合部9aの位置を、製品の中心Oよりずらして配置している。他の構成は上記実施例1と同じである。
【0026】
上記構成において、図5(a)に示すように、内蓋ユニット部材9aを表方向にして、内蓋ユニット部材8aの蓋係合部9aを保持穴10aに矢印方向に挿入してセットするときは、何ら問題なく挿入装着することができる。しかし、図5(b)に示すように、裏方向にセットするときは、外蓋4aの保持穴10aに対し、内蓋ユニット部材8aの蓋係合部9aは、左右逆の位置になるため、保持穴10aの横に配設したリブ16に干渉し、挿入装着することができない。
【0027】
これにより、手入れした内蓋ユニット部材8aを外蓋4aにセットする際に、消費者が確実にある一定方向のセットを行うことができ、表裏逆セットを未然に防ぐことができる。また、部品点数を削減し、分解性を向上することができる。
【0028】

図6に示すように、保持穴10bは、外蓋4bの前方下方に配設し、この保持穴10bに、内蓋ユニット部材8bの蓋係合部9bを矢印方向に挿入して、保持穴10bにより、内蓋ユニット部材8bを保持する。
【0029】
ここで、内蓋ユニット部材8bの蓋係合部9bの形状を、内蓋ユニット部材9bを裏方向にしてセットするとき、内蓋ユニット部材8bの蓋係合部9bが外蓋4bの壁17に干渉し、内蓋ユニット部材8bを表裏逆セットできないよう構成している。他の構成は上記実施例1と同じである。
【0030】
上記構成において、図6(a)に示すように、内蓋ユニット部材9bを表方向にして、内蓋ユニット部材8bの蓋係合部9bを保持穴10bに矢印方向に挿入してセットするときは、何ら問題なく挿入装着することができる。しかし、図6(b)に示すように、裏方向にセットするときは、内蓋ユニット部材8bの蓋係合部9bが外蓋4bの壁17に干渉し、内蓋ユニット部材8bを表裏逆セットすることができない。
【0031】
これにより、手入れした内蓋ユニット部材8bを外蓋4bにセットする際に、消費者が確実にある一定方向のセットを行うことができ、表裏逆セットを未然に防ぐことができる。また、部品点数を削減し、分解性を向上することができる。
【0032】
(実施例4)
図6に示すように、保持穴10cは、外蓋4cの前方下方に配設し、この保持穴10cに、内蓋ユニット部材8cの蓋係合部9cを矢印方向に挿入して、保持穴10cにより、内蓋ユニット部材8cを保持する。
【0033】
ピン18は、外蓋4cにばね19により上下動自在に設け、内蓋ユニット部材8cを表裏逆セットし挿入装着しようとしたときに、内蓋ユニット部材8cの蓋係合部9cに当たるように構成している。検知スイッチ20は内蓋ユニット部材8cの表裏逆セットを検知するもので、外蓋4cに配設している。他の構成は上記実施例1と同じである。
【0034】
上記構成において、図7(a)に示すように、内蓋ユニット部材9cを表方向にして、内蓋ユニット部材8cの蓋係合部9cを保持穴10cに矢印方向に挿入してセットするときは、何ら問題なく挿入装着することができる。しかし、図7(b)に示すように、裏方向にセットするときは、内蓋ユニット部材8cの蓋係合部9cがピン18に当たり、ピン18が上方向に移動し、ピン18により検知スイッチ20が働き、その時点で警告の音や表示により、消費者に表裏逆セットをしていることを報知し、未然に内蓋ユニット部材8cの表裏逆セットを防止することができる。
【0035】
【発明の効果】
また、請求項に記載の発明によれば、内蓋ユニット部材の表裏逆セットを防止するよう構成したから、手入れした内蓋ユニット部材を外蓋にセットする際に、消費者が確実にある一定方向のセットを行うことができ、表裏逆セットを未然に防ぐことができるとともに、部品点数を削減し、分解性を向上することができる。
