【発明の属する技術分野】
本発明は、水道蛇口と浄水器の間に配される切換弁に関し、さらに詳しくは水道蛇口に取り付けられ、原水の水路と浄水器に送水する水路に切り換え、かつ原水をストレート状またはシャワー状に吐水させる切換弁に関する。
【0002】
【従来の技術】
従来、切換弁として図9に示すような切換弁が知られている。図9において、1は切換弁本体、2は原水の水路、3は筒部で内部に水路が形成され軸線に対し回動自在となっており、4はパッキンで水路2と筒部3間を密接させ、5、6は開口部で筒部3の長手方向に位相をずらして設けられ、7はレバーで筒部3を回動させる、8は蛇口に取り付ける固定リング、9は開口部5と連通する原水ストレート流出口、10は開口部6と連通する原水シャワー流出口、11はシャワーキャップ嵌合用ネジ部である。
【0003】
図9に示す切換弁において、レバー7により筒部3を回動させ、筒部3の開口部5と原水ストレート流出口9とを合致させると、原水は切換弁本体1の下方よりストレート状に吐水する。レバー7により筒部3を回動させ、筒部3の開口部6と原水シャワー流出口10とを合致させると、原水は、切換弁本体1の下方よりシャワー状に吐水する。
【0004】
しかしながら、かかる従来の切換弁においては、回動自在の筒部にパッキンが密接しているため、筒部の回動での負荷が大きく、レバーが回し難いという難点があり、また、この負荷を低減するため、パッキンの筒部との接触部にグリースを塗布する手段もあるが、切換弁の使用時間が長くなると塗布したグリースが水で流出し、その効果が失われるという問題が生じていた。また、従来の切換弁においては、レバーを回して所定位置に固定するという操作を必要とするため、レバーを指でつまめないと切り換え操作ができないという煩わしさがあり、指が濡れていたり、手に物を持った状態では、レバーから指を滑らせたり、レバーそのものを回せない等切り換え操作に不都合がある。
【0005】
【発明が解決しようとする課題】
本発明の目的は、原水をストレート状またはシャワー状に吐水させる原水の水路と浄水器に送水する水路との切り換え操作での負荷が少なく、また簡単かつ安全に切り換え操作を行うことができる切換弁及び切換弁と浄水器との結合体を提供することにある。
【0006】
【課題を解決するための手段】
本発明の第一の要旨は、水道蛇口と浄水器の間に配される切換弁であって、蛇口と連結可能な原水流入口、原水をそのままストレート状またはシャワー状に吐水する各原水吐出口及び浄水器に接続可能な原水送水口を備えた切換弁本体の内部に、切換レバーの回動操作により各原水吐出口または原水送水口への水路の切り換えを行う水路切換機構を有し、該切換レバーによる回動伝達部にラチェット機構が配された切換弁であって、該切換レバーを戻しバネによって元の所定位置に復元する切換レバー復元機構が配されると共に、該切換弁本体に該戻しバネのバネ受けが配され、該切換レバーを押し下げる度に水路の切換が順次行われれる切換弁である。本発明の第二の要旨は、水道蛇口と浄水器の間に配される切換弁であって、蛇口と連結可能な原水流入口、原水をそのままストレート状またはシャワー状に吐水する各原水吐出口及び浄水器に接続可能な原水送水口を備えた切換弁本体の内部に、切換レバーの回動操作により各原水吐出口または原水送水口への水路の切り換えを行う水路切換機構を有し、該切換レバーによる回動伝達部にラチェット機構が配された切換弁であって、該切換レバーを戻しバネによって元の所定位置に復元する切換レバー復元機構が配されると共に、該切換レバーに該戻しバネのバネ受けが配され、該切換レバーを押し下げる度に水路の切換が順次行われれる切換弁である。
【0007】
【発明の実施の形態】
本発明の構成を図面に基づいて説明する。
図1は、本発明の切換弁の正面図、図2は、本発明の切換弁の下面図、図3は、図1のS−S横断面図である。図1〜図2において、21は切換弁本体、22は切換レバー、23は蛇口に固定しうる原水流入口、24は原水ストレート吐出口、25は原水シャワー吐出口、26は原水送水口を示す。図3において、38はラチェットホイール、39は回転掛け爪、40は戻しバネ、41はストッパー、42はバネ受けを示す。
【0008】
図1〜図2において、本発明の切換弁は、蛇口と連結固定可能な原水流入口23、原水をそのままストレート状に吐水する原水ストレート吐出口24、原水をそのままシャワー状に吐水する原水シャワー吐出口25及び浄水器に接続可能な原水送水口26を備え、切換弁本体21の内部に切換レバー22の回動操作により各原水吐出口24、25または原水送水口26への水路の切り換えを行う水路切換機構を有している。また、切換レバー22による回動伝達部には、ラチェットホイール38、回転掛け爪39からなるラチェット機構及び切換レバーを元の所定位置に復元する戻しバネ40、ストッパー41、バネ受け42からなる切換レバー復元機構が配設されている。
【0009】
切換弁本体21、切換レバー22の大きさ、形状は、特に制限されるものではないが、ABS樹脂、ポリカーボネート樹脂等の強靭性、耐圧性、耐熱性の硬質プラスチックであることが好ましい。原水送水口26は、浄水器に接続可能な構造とし、浄水器の接続部と着脱自在な嵌合構造とすることが好ましく、ネジ式、カプラー式、バヨネット式等のいずれでもよい。
【0010】
本発明の切換弁において、切換弁本体の内部に有する水路切換機構は、切換レバーの回転軸のアームにより移動して開口部をシールするボールによって水路が開閉するボール弁を用いた切換機構であることが好ましく、かかるボール弁方式の水路切換機構について図3〜図6にて説明する。図3は、図1のS−S横断面図、図4は、図3のA−A縦断面図、図5は、図3のB−B縦断面図、図6は、図3のC−C縦断面図である。
【0011】
図3において、27は浄水用シールボール、28は原水シャワー用シールボール、29は原水ストレート用シールボール、30はアームを軸対称に設けたアーム付き回転軸、31はOリング、32はワッシャー、33は止めビスを示す。また、図4〜図6において、34は原水流入口、35は原水シャワー用開口部、36は浄水用開口部、37は原水ストレート用開口部を示す。
【0012】
図3〜図6においては、原水送水口26への水路に切り換えられた状態を示すが、この切り換え状態では、図5に示すように、浄水用開口部36上に収まり浄水用開口部36を水圧によって閉塞する浄水用シールボール27は、アーム付き回転軸30の片側のアームによって押し上げられ、浄水用開口部36を開放し、原水送水口26への水路が形成される。一方、図4に示すように、原水シャワー用開口部35は、原水シャワー用シールボール28によって閉塞され、また図6に示すように、原水ストレート用開口部37は、原水ストレート用シールボール29によって閉塞され、それぞれ水路は形成されない。
【0013】
この切換弁における動作の違いは、アーム付き回転軸30のアームが回転軸30の長手方向に位相をずらして設けたことにより生じ、好ましくはアーム付き回転軸30におけるアームは、60゜ずつ位相をずらして設ける。従って、アーム付き回転軸30に連結した切換レバー22によってアーム付き回転軸30を60゜回動させると、原水シャワー用開口部35上に収まり原水シャワー用開口部35を水圧によって閉塞する原水シャワー用シールボール28は、アーム付き回転軸30の片側のアームによって押し上げられ、原水シャワー用開口部35を開放し、水路を形成する。一方、浄水用開口部36は、浄水用シールボール27によって閉塞され、また、原水ストレート用開口部37は、原水ストレート用シールボール29によってそれぞれ閉塞され、水路は形成されない。
【0014】
また、さらに切換レバー22によってアーム付き回転軸30を60゜回動させると、原水ストレート用開口部37上に収まり原水ストレート用開口部37を水圧によって閉塞する原水ストレート用シールボール29は、アーム付き回転軸30の片側のアームによって押し上げられ、原水ストレート用開口部37を開放し、水路を形成する。一方、浄水用開口部36は、浄水用シールボール27によって閉塞され、また、原水シャワー用開口部35は、原水シャワー用シールボール28によってそれぞれ閉塞され、水路は形成されない。かかる水路の切り換え操作は、切換レバー22によって順次或いは任意に行われる。
【0015】
水路切換機構の構成材質は、特に限定はされないが、シールボール27、28、29の材質としてはシール性に優れたNBR、シリコン等の軟質ゴムが好ましく、また、アーム付き回転軸30の材質としては耐圧性、耐摩耗性に優れたポリアセタール樹脂が好ましい。
【0016】
本発明の切換弁における切換レバーによる回動伝達部に配設されるラチェット機構及び切換レバー復元機構について、図7〜図8にてさらに詳しく説明する。図7は、切換レバー22による回動伝達部における構成の分解斜視図、図8はラチェット機構部の正面図である。図7において、アーム付き回転軸30の軸線上に配置され、ラチェットホイール38、回転掛け爪39からなるラチェット機構及び戻しバネ40、ストッパー41、バネ受け42からなる切換レバー復元機構が切換レバー22の根元部の回動伝達部に配設され、切換レバー22による回動操作に連動してラチェット機構及び切換レバー復元機構が作動すると共にアーム付き回転軸30が回動する。
【0017】
切換レバー22を60゜下方に押し下げると、回転掛け爪39が回転するが、この際、回転掛け爪39の掛け爪がラチェットホイール38の歯に掛かり、ラチェットホイール38及びアーム付き回転軸30を回転させる。切換レバー22を60゜下方に押し下げた状態を解除すると、切換レバー22のみは、バネ受け42で制限された戻しバネ40の反力により元の位置に戻る。切換レバー22の戻る位置の設定は、切換レバー22の根元部の回動伝達部の外周に凸設したストッパー41と切換弁本体21の外壁に凸設したストッパー41により行い、好ましくは切換レバー22の水平位置から切換レバー22が45゜上方になる位置になるように設定する。
【0018】
切換レバー22が元の位置に戻る際、回転掛け爪39も逆回転しようとするが、図8に示すように、回転掛け爪39の掛け爪を肉薄で柔軟性のあるものとすることにより、回転掛け爪39は、切換レバー22と共には逆回転せずにその位置に留まり、次の切換レバー22を60゜下方に押し下げる際にラチェットホイール38の次の歯に移動し得る状態に置かれる。
【0019】
以上の一回の切換レバーの回動操作が一つの水路切り換え操作単位として行われ、切換レバーを予め設定した所定の位置から60゜下方に押し下げる度に、水路切換機構のアーム付き回転軸30が同一方向に60゜ずつ回転して水路の切り換えが順次行われる。
【0020】
ラチェットホイール38、回転掛け爪39は、その大きさ、形状は、前記のような作動性を有するものであれば、特に限定はされないが、材質としてはポリアセタール樹脂等の耐圧性、耐摩耗性、強度に優れたプラスチックが好ましい。
【0021】
本発明の切換弁において、水路の切り換え順序、切換レバーの押し下げ角度、切換レバーの復元角度等は、前記記述に限定されるものではなく、適宜設定変更し得ることは勿論であり、また、切換レバーの押し倒す方向を切換レバーの押し下げではなく切換レバーの押し上げに代えることもできる。
【0022】
【実施例】
図1〜図8に、実施例として切換弁本体の内部にボール弁方式の切換機構を有し、切換レバー復元機能を有する切換弁の実施例の正面、下面及び主要箇所での横断面、縦断面、構成状態を示す。
【0023】
【発明の効果】
本発明の切換弁は、原水をストレート状またはシャワー状に吐水させる原水の水路と浄水器に送水する水路の切り換え操作を、切換レバーを一方向に押し倒すことにより行うことができ、復元する切換レバーを一方向に押し倒すだけで順次水路の切り換えが行えるので、指が濡れていたり、手に物を持った状態等でも切り換え操作が簡単、かつ安全に行える。また、切換弁本体内部の切換機構を、切換レバーの回転軸のアームにより移動するボールによって水路が開閉するボール弁を用いた切換機構とすることにより、切り換え操作での負荷が少なく、スムーズに行うことができる。本発明の切換弁は、水道蛇口に固定して用い、蛇口直結型或いは据置型の浄水器の原水流入口と接続させて、切換弁で原水のストレート状またはシャワー状の吐水を、また浄水器で浄水を得ることができる。

BACKGROUND OF THE INVENTION
The present invention relates to a switching valve disposed between a water faucet and a water purifier, and more specifically, is attached to a water faucet, switches between a raw water channel and a water channel that supplies water to the water purifier, and the raw water is straight or showered. The present invention relates to a switching valve for discharging water.
[0002]
[Prior art]
Conventionally, a switching valve as shown in FIG. 9 is known as a switching valve. In FIG. 9, 1 is a switching valve body, 2 is a raw water channel, 3 is a cylindrical part, and a water channel is formed therein and is rotatable with respect to the axis, and 4 is a packing between the water channel 2 and the cylindrical part 3. Closely attached, 5 and 6 are openings, and are provided with a phase shifted in the longitudinal direction of the cylindrical part 3, 7 is a lever that rotates the cylindrical part 3, 8 is a fixing ring attached to the faucet, 9 is an opening 5 The raw water straight outlet, 10 is a raw water shower outlet, communicating with the opening 6, and 11 is a shower cap fitting screw.
[0003]
In the switching valve shown in FIG. 9, when the cylindrical portion 3 is rotated by the lever 7 so that the opening 5 of the cylindrical portion 3 and the raw water straight outlet 9 are matched, the raw water is straightened from below the switching valve body 1. Water is discharged. When the cylindrical portion 3 is rotated by the lever 7 so that the opening 6 of the cylindrical portion 3 and the raw water shower outlet 10 are matched, the raw water is discharged from the lower side of the switching valve body 1 in a shower shape.
[0004]
However, in such a conventional switching valve, since the packing is in intimate contact with the rotatable cylinder portion, there is a problem that the load due to the rotation of the cylinder portion is large and the lever is difficult to turn. In order to reduce this, there is a means to apply grease to the contact part with the cylindrical part of the packing. However, if the switching valve is used for a long time, the applied grease will flow out with water, and the effect will be lost. .

A restoring mechanism is provided.
[0009]
The size and shape of the switching valve body 21 and the switching lever 22 are not particularly limited, but are preferably tough, pressure-resistant, heat-resistant hard plastics such as ABS resin and polycarbonate resin. The raw water feed port 26 has a structure that can be connected to a water purifier, and preferably has a fitting structure that can be freely attached to and detached from the connection portion of the water purifier, and may be any of a screw type, a coupler type, a bayonet type, and the like.
[0010]
In the switching valve of the present invention, the water channel switching mechanism in the switching valve body is a switching mechanism using a ball valve that opens and closes the water channel by a ball that is moved by the arm of the rotating shaft of the switching lever and seals the opening. The ball valve type water channel switching mechanism is preferably described with reference to FIGS. 3 is an SS cross-sectional view of FIG. 1, FIG. 4 is an AA longitudinal sectional view of FIG. 3, FIG. 5 is a BB longitudinal sectional view of FIG. 3, and FIG. -C is a longitudinal sectional view.
[0011]
In FIG. 3, 27 is a water-purifying seal ball, 28 is a raw water shower seal ball, 29 is a raw water straight seal ball, 30 is an arm-equipped rotating shaft, 31 is an O-ring, 32 is a washer, Reference numeral 33 denotes a set screw. 4 to 6, reference numeral 34 denotes a raw water inlet, 35 denotes a raw water shower opening, 36 denotes a water purification opening, and 37 denotes a raw water straight opening.
[0012]
3 to 6 show a state where the water channel to the raw water inlet 26 is switched. In this switched state, as shown in FIG. 5, the water purification opening 36 is accommodated on the water purification opening 36. The water-purifying seal ball 27 closed by water pressure is pushed up by an arm on one side of the arm-equipped rotating shaft 30 to open the water-purifying opening 36 and form a water channel to the raw water supply port 26. On the other hand, as shown in FIG. 4, the raw water shower opening 35 is closed by a raw water shower seal ball 28, and as shown in FIG. 6, the raw water straight opening 37 is formed by a raw water straight seal ball 29. They are blocked and no water channel is formed.
[0013]
The difference in the operation of the switching valve is caused by the fact that the arm of the rotary shaft 30 with the arm is provided with a phase shifted in the longitudinal direction of the rotary shaft 30. Preferably, the arm of the rotary shaft 30 with the arm has a phase of 60 °. Provide a staggered position. Therefore, when the arm-equipped rotating shaft 30 is rotated by 60 ° by the switching lever 22 connected to the arm-equipped rotating shaft 30, the raw water shower opening 35 is received on the raw water shower opening 35 and closed by the water pressure. The seal ball 28 is pushed up by an arm on one side of the rotary shaft 30 with an arm, opens the raw water shower opening 35, and forms a water channel. On the other hand, the water-purifying opening 36 is closed by the water-purifying seal ball 27, and the raw water straight opening 37 is closed by the raw water-straight sealing ball 29, so that no water channel is formed.
[0014]
Further, when the arm-equipped rotating shaft 30 is further rotated by 60 ° by the switching lever 22, the raw water straight seal ball 29 that fits on the raw water straight opening 37 and closes the raw water straight opening 37 by water pressure is provided with the arm. It is pushed up by an arm on one side of the rotating shaft 30 to open the raw water straight opening 37 and form a water channel. On the other hand, the water-purifying opening 36 is closed by the water-purifying seal ball 27, and the raw water shower opening 35 is closed by the raw water shower-sealing ball 28, so that no water channel is formed. Such a water channel switching operation is sequentially or arbitrarily performed by the switching lever 22.
[0015]
The material of the water channel switching mechanism is not particularly limited, but the material of the seal balls 27, 28, 29 is preferably a soft rubber such as NBR or silicon having excellent sealing properties, and the material of the rotating shaft 30 with the arm. Is preferably a polyacetal resin excellent in pressure resistance and wear resistance.
[0016]
The ratchet mechanism and the switching lever restoring mechanism disposed in the rotation transmission portion by the switching lever in the switching valve of the present invention will be described in more detail with reference to FIGS. FIG. 7 is an exploded perspective view of the configuration of the rotation transmission portion by the switching lever 22, and FIG. 8 is a front view of the ratchet mechanism portion. In FIG. 7, a ratchet mechanism including a ratchet wheel 38 and a rotation hooking claw 39 and a switching lever restoring mechanism including a return spring 40, a stopper 41, and a spring receiver 42 are arranged on the axis of the rotating shaft 30 with an arm. The ratchet mechanism and the switching lever restoring mechanism are operated in conjunction with the pivoting operation by the switching lever 22 and the armed rotary shaft 30 is pivoted.
[0017]
When the switching lever 22 is pushed downward by 60 °, the rotary hook 39 rotates. At this time, the hook of the rotary hook 39 engages with the teeth of the ratchet wheel 38 and rotates the ratchet wheel 38 and the arm-equipped rotary shaft 30. Let When the state in which the switching lever 22 is pushed down by 60 ° is released, only the switching lever 22 returns to the original position by the reaction force of the return spring 40 limited by the spring receiver 42. The return position of the switching lever 22 is set by a stopper 41 protruding from the outer periphery of the rotation transmission portion at the base of the switching lever 22 and a stopper 41 protruding from the outer wall of the switching valve body 21, preferably the switching lever 22. Is set so that the switching lever 22 is 45 ° above the horizontal position.
[0018]
When the switching lever 22 returns to the original position, the rotary hook 39 also rotates in the reverse direction, but as shown in FIG. 8, by making the hook of the rotary hook 39 thin and flexible, The rotary hook 39 stays at that position without rotating in reverse with the switching lever 22, and is placed in a state where it can move to the next tooth of the ratchet wheel 38 when the next switching lever 22 is pushed downward by 60 °.
[0019]
The rotation operation of the switching lever once is performed as one unit for switching the water channel, and each time the switching lever is pushed downward by 60 ° from a predetermined position, the rotary shaft 30 with the arm of the water channel switching mechanism is moved. The water channel is sequentially switched by rotating 60 ° in the same direction.
[0020]
