Description

【０００１】
〔産業上の利用分野〕
本発明は、水供給栓の先端と浄水器、軟水器、その他の水処理器とに接続して、水供給栓から供給される水の流れを切り換える弁装置に関する。
【０００２】
〔従来の技術〕
一般に、水道水などの水を処理して浄水等を得る水処理器に使用される水切り替え弁装置においては、原水ストレート、原水シャワー、それに浄水ストレートの三様の水を吐水させているが、浄水シャワーを吐水させる弁装置はない。
【０００３】
〔発明の解決しょうとする課題〕
浄水器等の水処理器の普及が高まるつれ、使用者より「浄水シャワー」があって欲しいとの要望が強まって来た。現今における使用者の浄水等処理水の使用法は、ただ単に飲水用や料理用の為だけにとどまらず、米や野菜、鮮魚鮮肉や豆腐、めん類等の食品の洗浄に及んでいる。洗浄にシャワー様吐水が要望されることは推測の域である。
【０００４】
本発明は、このような要望に答えるためになされたもので、構造が簡単で、従来のものよりコストを増加させることなく、尚資源も増量使用することなく、浄水等の処理水シャワー様吐水の出来る弁装置を供給し、水処理器使用者に、原水ストレート、原水シャワー、処理水ストレートに加えて、第４の生活水である処理水シャワーでの生活を供給することを目的としたものである。
【０００５】

【００３６】
操作レバーを原水ストレート位置に操作したときには、図２１に示すように、水は前述した処理水ストレート、処理水シャワー、原水シャワーと同様の経路を経て弁２内の原水流通部４１に至り、図２２に示すように、弁２の、原水流通部４１に連通した給水孔５２より弁箱１の出水口２５より出水し、原水ストレート用吐水口３２より吐水する。
【００３７】
操作レバーを逆洗位置に操作したときには、弁箱１内の弁２の位置は図２５、図２６、図２７、図２８、図３１に示す位置にあり、水は図２５に示す如く、水供給管５、弁箱１の、流入口２１、逆流防止弁室２２、取水口２４の経路で弁２の、取水孔５１より原水流通部４１へ入水し、図２８に示すごとく弁２の、原水流通部４１に連通した給水孔５３より、弁箱１の受水口３０へ逆に流入し、受水口ノズル３５より逆に流出し、ホースを介して水処理器７０の出口７１に逆に流入し、水処理器７０を逆方向に通過して逆流洗浄処理し、図２７に示すように水処理器７０の入口７１より出水して、ホースを介して弁箱１の、送水ノズル３４に入水し、給水口２９を経て弁２の、再入孔５８より、処理水通路４４へ流入し、図２６に示すように弁２の、処理水通路４４と連通した再出孔４７より弁箱１の排水口３１へ排水し、排出ノズル３６より吐水する。

By rotating the handle to the “treated water shower” position, the “treated water shower” is discharged from the valve box 1.
[0007]
When the handle 3 is set to the “treated water shower” position, water is introduced from the intake port 24 of the valve box 1 ──water is supplied from the water supply port 29 to the water treatment device 70 ──from the water treatment device 70 again. This is a route for receiving water at the water receiving port 30 of the box 1 and discharging water from the treated water shower outlet 27.
[0008]
When the handle 3 is in the “treated water shower” position, the water path of the valve 2 introduces raw water from the water intake hole 51 of the valve 2 into the raw water circulation part 41 in the valve --- from the water supply hole 54 --- Water is supplied to the inlet 71 of the treatment device 70, and is received from the outlet 72 of the water treatment device 70 to the re-entry hole 57, and the inside of the raw water circulation part 41 of the valve 2 is partitioned by the pipe wall 48. The treated water passage 43 passes through the treated water shower outlet 46 and is fed to the treated water outlet 27 of the valve box 1.
[0009]
The present invention having such a configuration constitutes the raw water circulation part 41 for introducing the raw water into the valve, and provides the treated water passage 43 separated from the raw water circulation part 41 by the pipe wall 48 to distribute the treated water. Due to the configuration of discharging water, a “treated water shower” can be added in a small and simple configuration.
