【発明の属する技術分野】
本発明は、濡れた手を乾燥させる乾燥機能を備えた手洗装置に関する。
【０００２】
【従来の技術】
この種の手洗装置として、本出願人は、図１２に示すようなものを先に提案している。
【０００３】
このものは、図１２に示すように、水受部５０の溢れ縁部の後部を上方に延出させた部分６０に洗浄液吐出部３００を設け、キャビネット部１１０には、洗浄液タンク５００と洗浄液を供給する洗浄液供給手段６００と洗浄液吐出部３００と洗浄液供給手段６００とを連絡する洗浄液供給管８００と、空気を供給する空気供給手段７００と洗浄液吐出部３００とを連絡する空気供給管９００が設けてある。
【０００４】
また、気体吹出口２００は洗浄液吐出部３００と対向する水受部５０の前面内部壁面に設けて、手洗い動作を行った後、移動することなく濡れた手を乾燥させるというものである。
【０００５】
【発明が解決しようとする課題】
しかしながら、上記の構成では、手を洗浄する際、洗浄液吐出部３００から吐出後、ムース状の洗浄液が表面張力にて洗浄液吐出部３００の先端部に残り、手４００を乾燥する際、気体吹出口２００から吹き出された気体が手４００に当り更に、水受部５０の内面に沿って流れ、洗浄液吐出部３００の先端部に当り、洗浄液吐出部３００先端部に付いた洗浄液が飛散し、身体やカウンターに付着し使用者に不快感を与えるものであった。
【０００６】
また、洗浄液を吐出した時、洗浄液を手４００に取らない場合、前記洗浄液吐出部の延長線上の、水受部５０の前面内部壁面上７０に洗浄液がつき、吐水しても洗浄液が流れず水受部５０の前面内部壁面上７０に残り、手４００を乾燥する際、気体吹出口２００から吹き出された気体が手４００に当り更に、水受部５０の内面に沿って流れ水受部５０の前面内部壁面上７０についた洗浄液が飛散し、身体やカウンターに付着し使用者に不快感を与えるものであった。
【０００７】
本発明は、上記課題を解決するためになされたもので、本発明の目的は、手を乾燥する際に、洗浄液吐出部や水受部の前面内部壁面上に残った洗浄液の飛散を防止し、清潔で快適な手洗装置を提供することにある。
【０００８】
【課題を解決するための手段】
上記目的を達成するために本発明は、水石けん等をムース状に吐出する洗浄液吐出部と、水又は湯を吐水する吐水口と、手に付着した水滴等を吹き飛ばす気体を吹き出す気体吹出口と、前記洗浄液吐出部からの洗浄液と前記吐水口からの吐水及び前記吹き飛ばされた水滴等を受ける水受部と、該水受部に排水口とを備え、前記気体吹出口は前記水受部の内部壁面に配設され、前記洗浄液吐出部は前記水受部の気体吹出口の対面側内壁面に設けるとともに下流側先端開口部の一部を外壁から開口中心に向かって閉塞する閉塞部を備えた吐出ノズルを備え、前記洗浄液吐出部に前記吐出ノズルの外周を筒側壁で囲った洗浄液飛散防止手段を設けたことを特徴としている。
【０００９】
従って、この構成によれば、手を乾燥する際に洗浄液吐出部の先端に付着した洗浄液の飛散が防止でき使用者に不快感を与えない清潔で快適な手洗装置を提供することができる。
また、前記気体吹出口から吹き出された気体が前記洗浄液吐出部の前記吐出ノズル先端に当りにくくなりなり前記洗浄液吐出部の前記吐出ノズル先端に付着した洗浄液の飛散を防止することができる。また、洗浄液の吐出角度を調整でき前記水受部にたまる洗浄液を少なくでき、洗浄液の飛散を防止できる。
【００１１】
また、前記筒壁面を洗浄液吐出部の吐出ノズルより着脱可能に構成にすれば、前記洗浄液吐出口の前記吐出ノズルの着脱がやりやすくなり前記吹出ノズル内部の清掃性が向上し、ノズル詰まり等による飛散を防止することができる。
【００１２】
また、前記洗浄液吐出部は、吐出ノズルを備え、前記吐出ノズルは、前記洗浄液吐出部より着脱可能に構成すれば、前記洗浄液吐出部の前記吐出ノズル内部の清掃性が向上し、ノズル詰まり等による飛散を防止できる。
【００１３】
また、前記洗浄液吐出部は、吐出ノズルを備え、前記洗浄液飛散防止手段は、洗浄液吐出上流側から下流側に向かって前記吐出ノズルの口径を徐々に狭くした構成すれば、洗浄液の吐出量が少なくでき前記洗浄液吐出部の吐出ノズル先端に残る洗浄液を減少でき洗浄液の飛散を防止できる。
【００１４】
また、前記洗浄液吐出部は、吐出ノズルを備え、前記洗浄液飛散防止手段は、前記吐出ノズルの下流側の外壁に溝を設けた構成にすれば、前記吐出ノズルの下流側の外壁の溝で洗浄液が前記洗浄液吐出部前記吐出ノズルの水受部の排水口側に沿って流れるのを防止することができる。
【００１６】
更に、前記閉塞部は、前記排水口側が開口するように閉塞した構成にすれば、前記洗浄液を前記水受部の前面内部壁面上の前記排水口方向に吐出できる。
【００１７】
更にまた、前記閉塞部は、前記吐出ノズルの先端開口部の約半分を閉塞した構成にすれば、前記洗浄液を前記水受部の前面内部壁面上の前記排水口近くに吐出でき、前記吐水口からの吐水にて前記洗浄液が流がれやすくなり前記水受部に洗浄液が残らず洗浄液の飛散を防止できる。
【００１９】
また、前記洗浄液吐出部の突起部先端外周に凹部を、前記突起部根元外周にはオスネジを設け、前記洗浄液吐出部の吐出ノズル根元外周に凸部を、前記洗浄液吐出部の吐出ノズル外周中ほどにおよそ垂直に突起部を、前記円筒壁面の内側中ほどにおよそ垂直に突起部を設け、前記突起部外周先端の凹部に、前記洗浄液吐出部の吐出ノズル根元外周の凸部を合せ、前記円筒壁面に設けたメスネジを前記洗浄液吐出部に設けたオスネジにねじ込み、前記洗浄液吐出部の吐出ノズル外周中ほどに設けたおよそ垂直な突起部を前記円筒側面内側中ほどのおよそ垂直な突起部で押さえ、固定する構成にすれば、前記洗浄液吐出部の吐出ノズルの位置決めと固定が容易に出来る。
【００２０】
また、前記洗浄液吐出部は、洗浄液を供給する洗浄液供給手段と、空気を供給する空気供給手段で構成され、前記洗浄液の吐出動作停止時には、前記空気供給手段の停止後、一定時間経過後に洗浄液供給手段を停止するようにすれば、前記洗浄液の吐出を停止した時前記洗浄液吐出部の吐出ノズル先端に残ったムース状の洗浄液を洗浄液で押出し前記洗浄液吐出部の吐出ノズル先端に洗浄液が残るのを防止できる。
【００２１】
また、前記空気供給手段は、供給する空気の量を調整するバルブを設けた構成にすれば、前記洗浄液吐出部の吐出ノズルから吐出されるムースの比重を調整でき、例えば、ムースの比重を重くすることにより、前記吐出ノズル先端にムースが残ることを防止し、洗浄液の飛散を防止できる。
【００２２】
なお、以上述べてきた洗浄液飛散防止手段は１つもしくは、組合わせて実施してもよい。
【００２３】
【発明の実施の形態】
以下に、本発明の実施の形態を添付図面に基づいて説明する。
【００２４】
図１は、本発明に係る手洗装置の全体構成を示す外観斜視図である。
図１に示すように、手洗装置は、水受部６の後部を上方に延出させて形成した部分に設けた水受部壁面に設けた洗浄液吐出部３及び、吐水口４と、水受部６前部の吐水口４と対応する部分に配設した気体吹出口２とを有する手洗器本体７とから構成されている。
【００２５】
洗浄液吐出部３の近傍には、差出された手を検出する手検出手段８が、吐水口４の近傍には、差出された手を検出する手検出手段９が、気体吹出口２の近傍には、差出された手を検出する手検出手段（図示せず)が設けられている。また、水受部６の下方部には、排水口５が設けられている。
【００２６】
手洗器本体７は、カウンター１０の略中央部に、例えば、セルフリミング式、フレーム式等の方式により取り付けられている。
【００２７】
カウンター１０の下方には、キャビネット部１１が設けられている。
【００２８】
図示はないが、キャビネット部１１内には、洗浄液供給手段、空気供給手段、水供給部、気体供給手段が設けられており、洗浄液吐出部、吐水口、気体吹出口と夫々連通継続されている。
【００２９】
また、各手検出手段からの検出信号に基づいて、各動作を制御する制御部が設けられている。
【００３０】
以上のように構成された手洗装置の作動について、以下に説明する。
【００３１】
使用者が洗浄液吐出部３付近に手を差出すと、その手を手検出手段８により検出し、その検出信号が制御部に入力されて、洗浄液供給手段が動作して洗浄液が洗浄液吐出部３に送られ、同時に空気供給手段が動作して空気が洗浄液吐出部３に送られ空気と洗浄液が混合されムース状で洗浄液吐出部３より吐出され、使用者は手洗浄動作を行うことができるが、洗浄液吐出部先端に表面張力により洗浄液が残る。また、吐出した洗浄液を手に取らない場合は、洗浄液が水受部の前面内部壁面上につき、吐水しても洗浄液が流れず水受部の前面内部壁面上に残る。
【００３２】
次に、使用者が吐水口４付近に手を差し出すと、その手を手検出手段９により検出し、その検出信号が制御部に入力されて、水供給部が動作して水供給管を介して吐水口４から水が吐水され、使用者は手洗い動作を行うことができる。
【００３３】
手洗い動作の後、濡れた手を気体吹出口２付近に差し出すと、その手を手検出手段により検出し、その検出信号が制御部に入力されて、気体供給手段が動作し気体供給管を介して気体吹出口２から高速の気体が吹き出され、手に付着した水等が吹き飛ばされて手の乾燥が行われる。
【００３４】
そして、吐出した洗浄液や吐水された水及び、吹き飛ばされた水等は、排水口５から排出される。
【００３５】
図２は、本発明に係る手洗装置の第１の実施例を示す外観斜視図である。
【００３６】

【００４５】
図５示すように、洗浄液吐出部３は洗浄液吐出部３上流側から下流側に向かって洗浄液吐出部３の吐出ノズル１２を細く、下流開口径を最小にしたものである。
【００４６】
このように構成すれば、洗浄液の吐出量が少なくでき洗浄液吐出部３の吐出ノズル１２に残る洗浄液を減少できる。
【００４７】
図６は、本発明に係る手洗装置の第５の実施例を示す外観斜視図である。
【００４８】
図６に示すように、洗浄液吐出部３の吐出ノズル１２ａの下流側先端側の外壁に溝１３を設けたものである。
【００４９】

【００５２】
このように構成すると、洗浄液の吐出角度が調整できる。
【００５３】
また、洗浄液吐出部３の吐出ノズル１２ｂの水受部６の排水口５側が開口するように閉塞したものである。
【００５４】

【００５７】
図９は、本発明に係る手洗装置の第７の実施例を示す部分断面図である。
【００５８】
図９に示すように、洗浄液吐出部３の吐出ノズル１２ｂの先端開口部方向１５を吐出ノズル１２ｂの中心線方向と所定の角度を成すように開口したものである。
【００５９】

【００６３】
また図示はないが、洗浄液の吐出動作停止時には、空気供給手段の停止後、一定時間停止後に洗浄液供給手段を停止するようにしている。
【００６４】
このように構成すると、洗浄液の吐出動作を停止した時に、洗浄液吐出部３の吐出ノズル１２ｂの先端に残ったムース状の洗浄液を洗浄液で押出し洗浄液吐出部３の吐出ノズル１２ｂの先端に洗浄液が残るのを防止できる。
【００６５】

【００６７】
このように構成すると、バルブ２７を閉めることにより、空気供給手段２６への空気供給量を少なくし、洗浄液の混合比率を多くすることで、吐出ノズル１２ｂから吐出されるムースの比重を重くすることができ、吐出ノズル１２ｂ先端にムースが残らず洗浄液の飛散を防止できる。
【００６８】
