【発明の属する技術分野】
本発明は、シンク底面に開口した排水口内に網かご及び排水トラップを設けたシンクの排水部を超音波で洗浄する洗浄装置に関するものである。
【0002】
【従来の技術】
従来より、シンク底面には排水口が開口してあり、この排水口内に網かごとその下方に排水トラップを設けて排水部が形成してある。このようなシンクにおいては、排水部の汚れ、即ち、排水部の内壁及び網かごに付着した汚れを除去し難いという問題があった。
【0003】
ところで、シンクに超音波発振源を設けた超音波式のシンク洗浄装置が知られている(例えば特許文献1,特許文献2,特許文献3参照)。これは、シンク内に溜まった水に超音波を発振する超音波発振源をシンク内壁に設け、前記水に浸漬された食器に付着している汚れを超音波によって落とすものである。
【0004】
このような超音波発振源を設けたシンクにおいては、シンク内の水に浸漬された食器の汚れを落とすことは出来るものの、シンクの排水部の内壁や網かごの汚れを汚れは超音波によって落とされず、たわし等によって手で擦り落とす必要のあるものであり、依然として汚れを除去し難いものであった。

【発明が解決しようとする課題】
本発明は上記の点に鑑みて発明したものであって、その目的とするところは、シンクの排水部に付着した汚れを容易に除去可能とするシンクの排水部の洗浄装置を提供することを課題とするものである。
【0007】
【課題を解決するための手段】
上記課題を解決するために本発明のシンクの排水部の洗浄装置にあっては、シンク底面1aに開口した排水口20内に網かご21及び排水トラップ22を設けたシンク1の排水部2の洗浄装置であって、下流端が排水部2に連通する給水路3を設けると共に該給水路3を開閉する給水弁30を設け、排水部2の下流側の排水管4を開閉する排水弁40を設けると共に排水部2の内壁に超音波発振器5を設け、使用者による操作部6の入操作によって排水弁40を閉じると共に給水弁30を開いて排水部2内に水を注入し、前記水に超音波発振器5により超音波を発振して排水部2を超音波洗浄し、所定時間経過後に超音波の発振を停止して排水弁40を開く制御部7を設けて成ることを特徴とするものである。このような構成とすることで、排水部2内の汚れを超音波によって落とすことができて、たわし等によって手で擦り落とす必要がなく、たわし等の届かない部分の汚れも落とすことが可能となり、また、これらの動作を制御部7によって自動で行うことが可能となる。
【0008】
また、排水部2内の水位を検知する水位検知手段8を設け、使用者による操作部6の入操作によって排水部2内に注入された水が前記水位検知手段8によって所定の水位であると検知された時に給水弁30を閉じる制御部7を設けることが好ましい。このような構成とすることで、超音波洗浄に係る一連の動作を制御部7によって全て自動で行うことが可能となる。
【0009】
また、排水部2内の水位を検知する水位検知手段8を設け、使用者による操作部6の入操作によって排水部2内に注入された水が前記水位検知手段8によって所定の水位であると検知された時に排水弁40を開く制御部7を設けることが好ましい。このような構成とすることで、シンク1内にまで溜まってしまった水を自動で排水することが可能となる。
【0010】
【発明の実施の形態】
本発明を添付図面に示す実施形態に基づいて説明する。
【0011】
シンク1は、図2に示すように、上方に開口して内部に水を貯留可能に形成してあり、この水に洗浄対象となる食器(特に図示せず)を浸漬する。食器は、食材を盛る器だけでなく、湯のみやグラス、箸やスプーン、鍋やフライパン、包丁やまな板等、キッチンで料理に用いる用具等も含まれる。シンクの内部に水を注ぎ込むための給水口11がシンクの上方に設けてある。
【0012】
図1に示すように、シンク1の底面1aには、シンク1内部の水を排水するための排水口20が形成してある。排水口20内には、網かご21を配設すると共にその更に下流側に排水トラップ22を設けて排水部2が形成してある。排水トラップ22の下流端には排水管4が接続してあり、排水管4は下水管(図示せず)へと通じている。そして、本発明においては、このような排水部2を超音波にて洗浄するもので、以下に説明する。
【0013】
シンク1の排水部2には、上述した給水口11とは別経路となる給水路3を接続するものである。本実施形態では、排水部2の網かご21が配設される部分(以下、網かご収容部23とする)の上端部の内壁に給水路3の下流端を接続してあり、更にこの給水路3はシンク1の側方においてシンク1より上方に伸びる縦管部31を有すると共に、縦管部31の上端部から側方に伸びる横管部32を有している。この給水路3は、その上流端が上水道(図示せず)に接続してあり、また、横管部32に給水弁30としての電磁弁を設けてあり、給水路3から排水部2へ水を自在に供給することができる。また、給水路3の横管部32には逆止弁33が設けてあると共に、縦管部31には水位検知手段8が設けてある。
【0014】
水位検知手段8は、排水部2又は給水路3に設けて水位が所定位置にまで上昇すると検知・作動するもので、本実施形態では、縦管部31の上記シンク1の排水口20とほぼ同じか若干下位のレベルに排水部2の満水を検知する水位センサーを設けると共に、縦管部31の前記満水を検知する水位センサーよりも上方に、排水部2からシンク1内の所定高さまで上昇した水位を検知する水位センサーを設けて構成してあり、これらについては後述する。
【0015】
排水部2より下流側の排水管4には、排水弁40としての電磁バルブが設けてあり、この排水弁40を閉じて排水部2内に水を溜めると共に、排水弁40を開いて排水部2内に溜まった水を排水することが可能となっている。
【0016】
そして、排水部2の内壁に超音波発振器5を設けるもので、本実施形態では網かご収容部23の内壁に設けてある。この超音波発振器5により、排水部2内に所定量の水が溜まった時に前記水に超音波を発振して排水部に汚れを落とすものである。この超音波発振器5をはじめ、上述した給水弁30としての電磁弁、排水弁40としての電磁バルブ、水位検知手段8、後述する操作部6は電気回路からなる制御部7により制御されて動作するもので、その動作について以下に説明する。なお、図1中の符号70は前記各構成要素と制御部7とを電気的に接続する電線を示す。
【0017】
排水部2の汚れを落とそうとする際、使用者は操作部6のスイッチを入操作する。操作部6は、図1に示すように制御部7と電線70にて接続されて制御部7に信号を送るもので、図2に示すようにシンク1の近傍に設けてある。
【0018】
操作部6にて入操作されると、排水弁40が閉じられると共に給水弁30が開かれて給水路3から排水部2内に水が注入される。そして、排水部2内及びこれに連通する給水路3内の水位が排水部2の上端部近傍にまで上昇すると、給水路3の縦管部31の水位検知手段8の水位センサーが検知・作動して給水弁30が閉じられる。このようにして排水部2内に水が充填されると、この水に超音波発振器5にて超音波を発振し、排水部2の内壁(網かご収容部23及び排水トラップ22の内壁)に付着した汚れや網かご21に付着した汚れが振動して剥がれ落ちる。そして、所定時間経過後に超音波発振器5による超音波の発振を停止し、排水弁40が開かれて排水部2内に充填された水を排水するものである。また、前記動作を数回繰返して1セットの動作としてもよい。
【0019】
また、排水部2内に水を充填して超音波洗浄を行っている際、何らかの原因によって、例えば給水口11から水をシンク1内に流したりして排水部2内の水がシンク1内に溢れ、シンク1内の水位が上昇して排水部2を介してシンク1内と連通する給水路3の水位が上昇し、縦管部31の上側の水位検知手段8の水位センサーが検知すると、排水弁40を開いてシンク1内及び排水部2内の水を排水するようにしてもよく、この場合、シンク1内にまで溜まってしまった水を自動で排水することが可能となる。
【0020】
なお、上述した動作は全て制御部7によって制御される。
【0021】
このように、シンク1内に水を注ぐ給水口11とは別経路の給水路3を設けてこの給水路3に給水弁30を設け、排水管4に排水弁40を設け、排水部2の内壁に超音波発振器5を設け、上述したような制御部7を設けたことで、排水部2内の汚れを超音波によって落とすことができて、従来のように汚れをたわし等によって手で擦り落とす必要がなく、たわし等の届かない部分の汚れも落とすことが可能となり、また、これらの動作を制御部7によって自動で行うことができる。
【0022】
【発明の効果】
上述のように請求項1記載の発明にあっては、シンク底面に開口した排水口内に網かご及び排水トラップを設けたシンクの排水部の洗浄装置であって、下流端が排水部に連通する給水路を設けると共に該給水路を開閉する給水弁を設け、排水部の下流側の排水管を開閉する排水弁を設けると共に排水部の内壁に超音波発振器を設け、使用者による操作部の入操作によって排水弁を閉じると共に給水弁を開いて排水部内に水を注入し、前記水に超音波発振器により超音波を発振して排水部を超音波洗浄し、所定時間経過後に超音波の発振を停止して排水弁を開く制御部を設けたので、排水部内の汚れを超音波によって落とすことができて、たわし等によって手で擦り落とす必要がなく、たわし等の届かない部分の汚れも落とすことが可能となり、また、これらの動作を制御部によって自動で行うことが可能となる。
【0023】
また請求項2記載の発明にあっては、請求項1記載の発明の効果に加えて、排水部内の水位を検知する水位検知手段を設け、使用者による操作部の入操作によって排水部内に注入された水が前記水位検知手段によって所定の水位であると検知された時に給水弁を閉じる制御部を設けたので、超音波洗浄に係る一連の動作を制御部によって全て自動で行うことが可能となる。
【0024】
また請求項3記載の発明にあっては、請求項1又は2記載の発明の効果に加えて、排水部内の水位を検知する水位検知手段を設け、使用者による操作部の入操作によって排水部内に注入された水が前記水位検知手段によって所定の水位であると検知された時に排水弁を開く制御部を設けたので、シンク内にまで溜まってしまった水を自動で排水することが可能となる。
