[Function and effect]
In 1st Embodiment comprised in this way, it can switch between purified water and raw | natural water by rotating the protrusion part 141 of the flow-path switching valve 140 along the outer peripheral surface of the holding | grip part 110, Moreover, purified water and raw | natural water Independent of the switching, the straight discharge and the shower discharge can be switched by operating the switching lever 151 of the discharge switching valve 150.
いま、流路切換弁140の設定位置を図4〜6に示すように外周側流路131を閉状態にするとともに中央空間部132を頭部120の空間120aと連通させた開状態にすると、把持部110のホース接続部114側から流入した混合水は、水質浄化用カートリッジ130の外周側流路131から水質浄化材133を透過して中央空間部132に流出することにより水質を浄化し、さらに浄化された混合水が中央空間部132から流路切換弁140に設けられたカートリッジ受け116の内面側の流路116b、弁体側に穿設された孔143eおよび弁座側に穿設された孔142eを介して頭部120の空間120aに流出し、この空間120aから集合通過部材126を介して吐出切換弁150の設定に従いストレート吐出流路127bまたはシャワー吐出面上流側空間120cに流入して、ストレート吐出またはシャワー吐出する。
Now, when the set position of the flow path switching valve 140 is closed as shown in FIGS. 4 to 6 and the central space 132 is communicated with the space 120a of the head 120 as shown in FIGS. The mixed water flowing in from the hose connection part 114 side of the grip part 110 purifies the water quality by passing through the water purification material 133 from the outer peripheral side flow path 131 of the water quality purification cartridge 130 and flowing out to the central space part 132, Further, the purified mixed water was drilled from the central space 132 to the channel 116b on the inner surface side of the cartridge receiver 116 provided in the channel switching valve 140, the hole 143e drilled on the valve body side, and the valve seat side. It flows out into the space 120a of the head 120 through the hole 142e, and the straight discharge passage 127b is set from the space 120a through the collective passage member 126 according to the setting of the discharge switching valve 150. Other flows into the shower discharge surface upstream space 120c, straightening the discharge or shower discharge.
次に、この浄水吐出をしている場合に、流路切換弁140の突出部141を把持部110の外周面に沿い所定方向へ必要角度回動して、流路切換弁140を図40〜42に示すように外周側流路131を流路切換弁140に設けられたカートリッジ受け116の外面側の流路116a、弁体側に穿設された孔143fおよび弁座側に穿設された孔142eを介して頭部120の空間120aと連通した開状態にするとともに中央空間部132を閉状態にすると、把持部110のホース接続部114側から流入した混合水が、外周側流路131から流路切換弁140に設けられたカートリッジ受け116の外面側の流路116a、弁体側に穿設された孔143fおよび弁座側に穿設された孔142eを介して頭部120の空間120aに流出し、この空間120aから集合通過部材126を介して吐出切換弁150の設定に従いストレート吐出流路127bまたはシャワー吐出面上流側空間120cに流入して、ストレート吐出またはシャワー吐出する。
その後、流路切換弁140の突出部141を把持部110の外周面に沿って、原水吐出の場合と逆方向へ同じ角度回動すると、図4〜6に示すような浄水吐出の場合に戻り、浄水を吐出することができるようになる。
Next, when this water purification discharge is performed, the protrusion 141 of the flow path switching valve 140 is rotated by a necessary angle in a predetermined direction along the outer peripheral surface of the gripping section 110, so that the flow path switching valve 140 is changed from FIG. As shown in FIG. 42, the outer peripheral side channel 131 is formed on the outer surface side of the cartridge receiver 116 provided in the channel switching valve 140, the hole 143f formed on the valve body side, and the hole formed on the valve seat side. When the central space portion 132 is closed while the space 120a of the head 120 is communicated with the space 120a via 142e, the mixed water that has flowed in from the hose connection portion 114 side of the grasping portion 110 is discharged from the outer circumferential side channel 131. The space 120a of the head 120 is passed through the flow path 116a on the outer surface side of the cartridge receiver 116 provided in the flow path switching valve 140, the hole 143f drilled on the valve body side, and the hole 142e drilled on the valve seat side. Leaked It flows into the straight discharge passage 127b or shower discharge surface upstream space 120c in accordance with the setting of the discharge switching valve 150 from the space 120a through the collection passage member 126, to the straight discharge or shower discharge.
After that, when the protruding portion 141 of the flow path switching valve 140 is rotated along the outer peripheral surface of the gripping portion 110 by the same angle in the opposite direction to that of the raw water discharge, the flow returns to the case of the clean water discharge as shown in FIGS. It becomes possible to discharge purified water.
また、吐出切換弁150の操作については、流路切換弁140の操作とは独立にでき、ストレート吐出とシャワー吐出とを任意に設定することができる。
まず、切換レバー151を操作して弁軸151aの軸心を中心にしてストレート吐出側に回動すると、弁体150aがストレート吐出用流路形成部材127の開口127aの位置から外れ、集合通過部材126から流出する混合水がストレート吐出用流路形成部材127の開口127aへ流入し、ストレート吐出流路127bの内部を通過してストレート吐出口122から吐出するようになる。
Further, the operation of the discharge switching valve 150 can be performed independently of the operation of the flow path switching valve 140, and straight discharge and shower discharge can be arbitrarily set.
First, when the switching lever 151 is operated and rotated to the straight discharge side about the axis of the valve shaft 151a, the valve body 150a is disengaged from the position of the opening 127a of the straight discharge flow path forming member 127, and the collective passage member. The mixed water flowing out from 126 flows into the opening 127a of the straight discharge flow path forming member 127, passes through the inside of the straight discharge flow path 127b, and is discharged from the straight discharge port 122.
そして、切換レバー151がストレート吐出側に設定されている場合に、切換レバー151を反対方向へ操作して、弁軸151aの軸心を中心にしてシャワー吐出側に回動すると、図4または41に示すように、弁体150aの皿部150bがストレート吐出用流路形成部材127の開口127aの上部に位置して開口127aを塞ぎ、集合通過部材126から流出する混合水が弁体150aの皿部150bに阻まれてストレート吐出用流路形成部材127の周囲に流出し、仕切部材125とシャワープレート121によって形成されたシャワー吐出面上流側空間120cを介してシャワー吐出口123から吐出するようになる。
その後、切換レバー151を操作して弁軸151aの軸心を中心にしてストレート吐出側に回動すると、前述のように、ストレート吐出口122から吐出するようになる。
When the switching lever 151 is set to the straight discharge side, when the switching lever 151 is operated in the opposite direction and rotated to the shower discharge side about the axis of the valve shaft 151a, FIG. As shown in FIG. 5, the plate portion 150b of the valve body 150a is positioned above the opening 127a of the straight discharge flow path forming member 127 so as to close the opening 127a, and the mixed water flowing out from the collective passage member 126 becomes the plate of the valve body 150a. So as to flow out around the straight discharge flow path forming member 127 and be discharged from the shower discharge port 123 via the shower discharge surface upstream space 120c formed by the partition member 125 and the shower plate 121. Become.
After that, when the switching lever 151 is operated and rotated to the straight discharge side around the axis of the valve shaft 151a, the straight discharge port 122 discharges as described above.
これにより、流路切換弁140の突出部141を把持部110の中心軸回りかつ外周面に沿って回動することにより、浄水吐出と原水吐出とを容易に切り換えることができ、浄水吐出時には、混合水が水質浄化用カートリッジ130の外周側流路131から中央空間部132へと、水質浄化材133を通過する際に浄化されるようになり、また、原水吐出時には、水質浄化用カートリッジ130の水質浄化材133よりも上流側の流路が、フィルタ134の表面側を通過する混合水によって、浄水吐出時に溜まったフィルタ表面の蓄積物が洗い流され、目詰りを起こりにくくするとともに水質浄化材133の劣化を防止するようになり、長期間、水質浄化性能を高レベルに維持できるようになる。
これに加えて、吐出切換弁150が流路切換弁140と完全に独立しているため、原水と浄水のどちらが吐出される場合であっても、ストレート吐出またはシャワー吐出のいずれかを選択して吐出させることができ、4種類の利用可能な形態が選択できるようになる。
Thereby, by rotating the protrusion 141 of the flow path switching valve 140 around the central axis of the gripping part 110 and along the outer peripheral surface, it is possible to easily switch between purified water discharge and raw water discharge. The mixed water is purified when passing the water purification material 133 from the outer peripheral flow path 131 of the water purification cartridge 130 to the central space 132, and when the raw water is discharged, the water purification cartridge 130 The flow path upstream of the water purification material 133 is washed away by the mixed water passing through the surface side of the filter 134, and the accumulation on the filter surface accumulated during the purification water discharge is washed away. As a result, the water purification performance can be maintained at a high level for a long period of time.
In addition to this, since the discharge switching valve 150 is completely independent of the flow path switching valve 140, it is possible to select either straight discharge or shower discharge regardless of whether raw water or purified water is discharged. It can be discharged and four types of available forms can be selected.
〔第2実施形態〕
前記第1実施形態は水質浄化用カートリッジの外周側を浄化前の上流側流路として形成されているが、この第2実施形態では、水質浄化用カートリッジの中央空間部を浄化前の上流側流路として形成した場合について具体的に説明する。
以下の説明では、各部材の符号は200番台の番号にして第1実施形態と識別することにし、また、流路切換弁の構成に係る部材以外の部材については、第1実施形態と同じ構成にするとともに符号を200番台の下2桁の番号を同じにして説明を省略する。

いま、流路切換弁240の設定位置が図43〜45に示すように中央空間部232を閉状態にするとともに外周側流路231を頭部220の空間220aと連通させた開状態にすると、把持部210のホース接続部214側から流入した混合水が、水質浄化用カートリッジ230の中央空間部232から水質浄化材233を透過して外周側流路231に流出することにより水質を浄化し、さらに浄化された混合水が外周側流路231から流路切換弁240に設けられたカートリッジ受け外面側の流路216a、弁体側に形成された孔243fおよび弁座側に形成された孔242eを介して頭部220の空間220aに流出し、この空間220aから集合通過部材226を介して吐出切換弁250の設定に従いシャワー吐出面上流側空間220cまたはストレート吐出流路227bに流入して、浄化された混合水がストレート吐出またはシャワー吐出する。
Now, when the set position of the flow path switching valve 240 is closed as shown in FIGS. 43 to 45, and the outer peripheral flow path 231 is in communication with the space 220 a of the head 220, The mixed water that has flowed in from the hose connection part 214 side of the grip part 210 passes through the water purification material 233 from the central space part 232 of the water purification cartridge 230 and flows out to the outer peripheral flow path 231 to purify the water quality. Further, the purified mixed water flows from the outer circumferential side channel 231 to the cartridge receiving outer surface side channel 216a provided in the channel switching valve 240, the hole 243f formed on the valve body side, and the hole 242e formed on the valve seat side. To the space 220a of the head portion 220 through the space 220a, and from the space 220a through the collecting passage member 226, according to the setting of the discharge switching valve 250, the shower discharge surface upstream space 220. Or flows into the straight discharge passage 227b, clarified mixed water is straight discharge or shower discharge.
次に、この浄水吐出をしている場合に、流路切換弁240の突出部241を把持部210の外周面に沿い所定方向へ必要角度回動して、図56〜58に示すように、中央空間部232、流路切換弁240に設けられたカートリッジ受け内面側の流路216b、弁体側に形成された孔243eおよび弁座側に形成された孔242eを頭部220の空間220aと連通させて開状態にするとともに外周側流路231を閉状態にすると、把持部210のホース接続部214側から流入した混合水が、中央空間部232から流路切換弁240に設けられたカートリッジ受け内面側の流路216b、弁体側に形成された孔243eおよび弁座側に形成された孔242eを介して頭部220の空間220aに流出し、この空間220aから集合通過部材226を介して吐出切換弁250の設定に従いシャワー吐出面上流側空間220cまたはストレート吐出流路227bに流入して、混合水が浄化されずに、原水のままストレート吐出またはシャワー吐出する。
その後、流路切換弁240の突出部241を把持部210の外周面に沿って、原水吐出の場合と逆方向へ同じ角度回動すると、図43〜45に示すような浄水吐出の場合に戻り、浄水を吐出することができるようになる。
Next, when this water purification discharge is performed, the projecting portion 241 of the flow path switching valve 240 is rotated by a necessary angle in a predetermined direction along the outer peripheral surface of the gripping portion 210, and as shown in FIGS. The central space 232, the flow path 216b on the inner surface of the cartridge receiver provided in the flow path switching valve 240, the hole 243e formed on the valve body side, and the hole 242e formed on the valve seat side communicate with the space 220a of the head 220. When the outer peripheral side flow path 231 is closed, the mixed water flowing in from the hose connection part 214 side of the gripping part 210 is received from the central space part 232 in the cartridge switching valve 240. It flows out into the space 220a of the head 220 through the flow path 216b on the inner surface side, the hole 243e formed on the valve body side, and the hole 242e formed on the valve seat side, and the collective passage member 2 from this space 220a 6 flows into the shower discharge surface upstream space 220c or straight discharge passage 227b in accordance with the setting of the discharge switching valve 250 through the mixing water without being purified, is straight discharge or shower discharge remains raw.
Thereafter, when the projecting portion 241 of the flow path switching valve 240 is rotated along the outer peripheral surface of the gripping portion 210 by the same angle in the opposite direction to the raw water discharge, the flow returns to the case of the clean water discharge as shown in FIGS. It becomes possible to discharge purified water.
また、吐出切換弁250の操作については、第1実施形態の場合と同様に切換レバー251を操作して混合水をストレート吐出またはシャワー吐出させることができる。
まず、切換レバー251を操作してストレート吐出側に回動すると、弁体250aがストレート吐出用流路形成部材227の開口227aの位置から外れ、集合通過部材226から流出する混合水がストレート吐出用流路形成部材227の開口227aへ流入し、ストレート吐出流路227bを通過してストレート吐出口222から吐出するようになる。
As for the operation of the discharge switching valve 250, the mixed water can be discharged straight or discharged by operating the switching lever 251 as in the case of the first embodiment.
First, when the switching lever 251 is operated and rotated to the straight discharge side, the valve body 250a is disengaged from the position of the opening 227a of the straight discharge flow path forming member 227, and the mixed water flowing out from the collecting passage member 226 is used for straight discharge. It flows into the opening 227a of the flow path forming member 227, passes through the straight discharge flow path 227b, and is discharged from the straight discharge port 222.
そして、切換レバー251がストレート吐出側に設定されている場合に、切換レバー251を反対方向へ操作してシャワー吐出側に回動すると、図44または57に示すように、弁体250aの皿部250bがストレート吐出用流路形成部材227の開口227aの上部に位置して開口227aを塞ぎ、集合通過部材226から流出する混合水が弁体250aの皿部250bに阻まれてストレート吐出用流路形成部材227の周囲に流出し、仕切部材225とシャワープレート221によって形成されたシャワー吐出面上流側空間220cを介してシャワー吐出口223から吐出するようになる。
その後、切換レバー251を操作してストレート吐出側に回動すると、前述のように、ストレート吐出口222からの吐出に変わる。
Then, when the switching lever 251 is set to the straight discharge side, when the switching lever 251 is operated in the opposite direction and rotated to the shower discharge side, as shown in FIG. 44 or 57, the plate portion of the valve body 250a 250b is positioned above the opening 227a of the straight discharge flow path forming member 227, closes the opening 227a, and the mixed water flowing out of the collective passage member 226 is blocked by the plate portion 250b of the valve body 250a, and the straight discharge flow path The liquid flows out around the forming member 227 and is discharged from the shower discharge port 223 through the shower discharge surface upstream space 220 c formed by the partition member 225 and the shower plate 221.
Thereafter, when the switching lever 251 is operated and rotated to the straight discharge side, the discharge is changed from the straight discharge port 222 as described above.
これにより、流路切換弁240の突出部241を把持部210の中心軸回りかつ外周面に沿って回動することにより、浄水吐出と原水吐出とを容易に切り換えることができ、浄水吐出時には、混合水が水質浄化用カートリッジ230の中央空間部232から外周側流路231へと水質浄化材233を通過する際に浄化されるようになり、また、原水吐出時には、水質浄化用カートリッジ230の水質浄化材233よりも上流側の流路が、フィルタ235の表面側を通過する混合水によって、浄水吐出時に溜まったフィルタ表面の蓄積物が洗い流され、目詰りを起こりにくくするとともに水質浄化材233の劣化を防止するようになり、長期間、水質浄化性能を高レベルに維持できるようになる。
これに加えて、吐出切換弁250が流路切換弁240と完全に独立しているため、原水と浄水のどちらが吐出される場合であっても、ストレート吐出またはシャワー吐出のいずれかを選択して吐出させることができ、4種類の利用可能な形態が選択できるようになる。
Thereby, by rotating the protrusion part 241 of the flow path switching valve 240 around the center axis of the grip part 210 and along the outer peripheral surface, it is possible to easily switch between purified water discharge and raw water discharge. The mixed water is purified when it passes through the water purification material 233 from the central space 232 of the water purification cartridge 230 to the outer peripheral flow path 231, and when the raw water is discharged, the water quality of the cartridge for water purification 230 is improved. The flow path on the upstream side of the purification material 233 is washed away by the mixed water passing through the surface side of the filter 235, so that the accumulated matter on the filter surface accumulated during the purification water discharge is washed away, and clogging is less likely to occur. Deterioration is prevented and water purification performance can be maintained at a high level for a long period of time.
In addition to this, since the discharge switching valve 250 is completely independent of the flow path switching valve 240, either straight discharge or shower discharge is selected regardless of whether raw water or purified water is discharged. It can be discharged and four types of available forms can be selected.
〔第3実施形態〕
前記の第1実施形態または第2実施形態は水質浄化用カートリッジの下流側に原水と浄水との吐出を選択する流路切換弁を設けているが、この第3実施形態では水質浄化用カートリッジの上流側に流路切換弁を設け、原水を水質浄化用カートリッジの外周側に形成された流路まで導き入れて外周側から中心部の中央空間部まで通過する間に浄化されるようにした場合について具体的に説明する。
以下の説明では、各部材の符号は300番台の番号にして第1実施形態と識別することにし、また、流路切換弁の構成に係る部材以外の部材については、第1実施形態と同じ構成にするとともに符号を300番台の下2桁の番号を同じにして説明を省略する。

[Function and effect]
In the third embodiment configured as described above, the water purifier is obtained by rotating the protruding portion 341 of the flow path switching valve 340 provided at the end of the gripping portion 310 on the hose connection side along the outer peripheral surface of the gripping portion 310. It is possible to switch between straight discharge and shower discharge by operating the switching lever 351 of the discharge switching valve 350 independently of switching between purified water and raw water.
いま、流路切換弁340の設定位置を図62〜64に示すように流路切換弁340の突出部341を浄水吐出位置に合わせた場合、流路切換弁340の弁座側に穿設された孔342eに弁体側に穿設された孔343eの位置が同軸的に一致して、水質浄化用カートリッジ330の外周側流路331を流路切換弁340の入口側と連通した開状態にする。このとき、混合水が把持部310のホース接続部314側から把持部310内に流入し、流入した混合水が流路切換弁340の弁座側に穿設された孔342e、弁体側に穿設された孔343eおよびカートリッジ受け317の外面側の流路317aを介して水質浄化用カートリッジ330の外周側流路331からフィルタ334および水質浄化材333を透過して中央空間部332に流出し、水質を浄化し、中央空間部332が頭部320の空間320aと連通しているから、浄化された混合水が中央空間部332からカートリッジ受け316の内面側の流路316bを介して頭部320の空間320aに流出する。そして、この空間320aから集合通過部材326を介して吐出切換弁350の設定に従い、ストレート吐出流路327bまたはシャワー吐出面上流側空間320cに流入して、ストレート吐出またはシャワー吐出する。
Now, when the set position of the flow path switching valve 340 is set to the clean water discharge position as shown in FIGS. 62 to 64, the flow path switching valve 340 is formed on the valve seat side of the flow path switching valve 340. The position of the hole 343e drilled on the valve element side coincides with the hole 342e coaxially, and the outer peripheral flow path 331 of the water purification cartridge 330 is brought into an open state communicating with the inlet side of the flow switching valve 340. . At this time, the mixed water flows from the hose connection part 314 side of the gripping part 310 into the gripping part 310, and the mixed water that has flowed into the hole 342e formed on the valve seat side of the flow path switching valve 340 and the valve body side. The filter 334 and the water purification material 333 are transmitted from the outer peripheral side flow path 331 of the water purification cartridge 330 through the hole 343e and the flow path 317a on the outer surface side of the cartridge receiver 317, and flow into the central space portion 332, The water quality is purified, and the central space portion 332 communicates with the space 320a of the head portion 320. Therefore, the purified mixed water flows from the central space portion 332 through the flow path 316b on the inner surface side of the cartridge receiver 316. To the space 320a. Then, in accordance with the setting of the discharge switching valve 350 from the space 320a through the collective passage member 326, it flows into the straight discharge flow path 327b or the shower discharge surface upstream side space 320c, and performs straight discharge or shower discharge.
次に、この浄水吐出をしている場合に、流路切換弁340の突出部341を把持部310の外周面に沿い所定方向へ必要角度回動して、図81〜83に示すように流路切換弁340を原水吐出位置に合わせた場合、流路切換弁340の弁座側に穿設された孔342eに弁体側に穿設された孔343fの位置が同軸的に一致して、水質浄化用カートリッジ330の外周側流路331を流路切換弁340の入口側と遮断した閉状態にし、水質浄化用カートリッジ330の中央空間部332を流路切換弁340の入口側と連通した開状態にする。
Next, when this clean water discharge is performed, the protrusion 341 of the flow path switching valve 340 is rotated by a necessary angle in a predetermined direction along the outer peripheral surface of the gripping portion 310 to flow as shown in FIGS. When the path switching valve 340 is adjusted to the raw water discharge position, the position of the hole 343f drilled on the valve body side coincides with the hole 342e drilled on the valve seat side of the flow path switching valve 340, so that the water quality The outer peripheral side flow path 331 of the purification cartridge 330 is closed from the inlet side of the flow path switching valve 340, and the central space 332 of the water quality purification cartridge 330 is opened to communicate with the inlet side of the flow path switching valve 340.

At this time, when mixed water flows in from the hose connection portion 314 side of the grip portion 310, a hole 342e drilled in the valve seat side of the flow path switching valve 340, a hole 343f drilled in the valve body side, and Since it flows into the central space 332 via the flow path 317b on the inner surface side of the cartridge receiver 317 and the central space 332 communicates with the space 320a of the head 320, the mixed water is not purified and is directly received in the cartridge receiver. It flows out to the space 320a of the head 320 through the flow path 316b on the inner surface side of 316.
そして、この空間320aから集合通過部材326を介して吐出切換弁350の設定に従いストレート吐出流路327bまたはシャワー吐出面上流側空間320cに流入して、ストレート吐出またはシャワー吐出する。
その後、流路切換弁340の突出部341を把持部310の外周面に沿って、原水吐出の場合と逆方向へ同じ角度回動すると、図62〜63に示すような浄水吐出の場合に戻り、浄水を吐出することができるようになる。
Then, it flows into the straight discharge flow path 327b or the shower discharge surface upstream space 320c from the space 320a through the collective passage member 326 according to the setting of the discharge switching valve 350, and performs straight discharge or shower discharge.
Thereafter, when the projecting portion 341 of the flow path switching valve 340 is rotated along the outer peripheral surface of the gripping portion 310 by the same angle in the opposite direction to that of the raw water discharge, the flow returns to the case of the clean water discharge as shown in FIGS. It becomes possible to discharge purified water.
また、吐出切換弁350の操作については、流路切換弁340の操作とは独立にでき、ストレート吐出とシャワー吐出とを任意に設定することができる。
まず、切換レバー351を操作して弁軸の軸心を中心にしてストレート吐出側に回動すると、弁体350aがストレート吐出用流路形成部材327の開口327aの位置から外れ、集合通過部材326から流出する混合水がストレート吐出用流路形成部材327の開口327aへ流入し、ストレート吐出流路327bの内部を通過してストレート吐出口322から吐出するようになる。
Further, the operation of the discharge switching valve 350 can be made independent of the operation of the flow path switching valve 340, and straight discharge and shower discharge can be arbitrarily set.
First, when the switching lever 351 is operated to rotate to the straight discharge side about the axis of the valve shaft, the valve body 350a is disengaged from the position of the opening 327a of the straight discharge flow path forming member 327, and the collective passage member 326 is moved. The mixed water flowing out of the straight gas flows into the opening 327a of the straight discharge flow path forming member 327, passes through the inside of the straight discharge flow path 327b, and is discharged from the straight discharge port 322.
そして、切換レバー351がストレート吐出側に設定されている場合に、切換レバー351を反対方向へ操作して、弁軸の軸心を中心にしてシャワー吐出側に回動すると、図63または82に示すように、弁体350aの皿部350bがストレート吐出用流路形成部材327の開口327aの上部に位置して開口327aを塞ぎ、集合通過部材326から流出する混合水が弁体350aの皿部350bに阻まれてストレート吐出用流路形成部材327の周囲に流出し、仕切部材325とシャワープレート321によって形成されたシャワー吐出面上流側空間320cを介してシャワー吐出口323から吐出するようになる。
その後、切換レバー351を操作して弁軸の軸心を中心にしてストレート吐出側に回動すると、前述のように、ストレート吐出口322から吐出するようになる。
Then, when the switching lever 351 is set to the straight discharge side, when the switching lever 351 is operated in the opposite direction and rotated to the shower discharge side about the axis of the valve shaft, FIG. 63 or 82 is obtained. As shown, the dish part 350b of the valve body 350a is positioned above the opening 327a of the straight discharge flow path forming member 327, closes the opening 327a, and the mixed water flowing out from the collective passage member 326 is the dish part of the valve body 350a. It is blocked by 350 b and flows out around the straight discharge flow path forming member 327, and is discharged from the shower discharge port 323 through the shower discharge surface upstream space 320 c formed by the partition member 325 and the shower plate 321. .
Thereafter, when the switching lever 351 is operated to turn to the straight discharge side around the axis of the valve shaft, the discharge is made from the straight discharge port 322 as described above.
これにより、流路切換弁340の突出部341を把持部310の中心軸回りかつ外周面に沿って回動することにより、浄水吐出と原水吐出とを容易に切り換えることができ、浄水吐出時には、混合水が水質浄化用カートリッジ330の外周側流路331から中央空間部332へと、水質浄化材333を通過する際に浄化されるようになる。
これに加えて、吐出切換弁350が流路切換弁340と完全に独立しているため、原水と浄水のどちらが吐出される場合であっても、ストレート吐出またはシャワー吐出のいずれかを選択して吐出させることができ、4種類の利用可能な形態が選択できるようになる。
Thereby, by rotating the protrusion part 341 of the flow path switching valve 340 around the central axis of the grip part 310 and along the outer peripheral surface, it is possible to easily switch between purified water discharge and raw water discharge. The mixed water is purified when it passes through the water purification material 333 from the outer peripheral channel 331 of the water purification cartridge 330 to the central space 332.
In addition, since the discharge switching valve 350 is completely independent of the flow path switching valve 340, either straight discharge or shower discharge can be selected regardless of whether raw water or purified water is discharged. It can be discharged and four types of available forms can be selected.
〔第4実施形態〕

When the holes 443e or 443f of the forming member 443 are aligned on the same central axis, the valve is opened with respect to the purified water side flow path or the raw water side flow path, respectively, and the mixed water passes through the open side flow path. .
吐出切換弁450は、弁体450aが仕切部材425の下流側で集合通過部材426から僅かに隙間をあけた直近の下流に配置され、弁体450aの下面をストレート吐出用流路形成部材427の上端に形成された開口427aに接触できる直近の位置に配置して、ストレート吐出用流路形成部材427の蓋として上部から覆いかぶさることができるようにし、また、切換レバー451の操作によって、弁体450aが開口427aの真上の位置から弁体450aの全体が開口427aの位置から外れるまでの範囲で、弁体450aがストレート吐出用流路形成部材427の上端に出入り自在に回動できるように、切換レバー451の回動角度を設定する。
The discharge switching valve 450 is disposed immediately downstream of the partition member 425 with the valve body 450a slightly spaced from the collective passage member 426, and the lower surface of the valve body 450a is connected to the straight discharge flow path forming member 427. It is arranged at the nearest position where it can come into contact with the opening 427a formed at the upper end so that it can be covered from the top as a lid of the straight discharge flow path forming member 427, and the valve body is operated by operating the switching lever 451. The valve body 450a can freely rotate in and out of the upper end of the straight discharge flow path forming member 427 in a range from 450a to a position immediately above the opening 427a until the entire valve body 450a is disengaged from the position of the opening 427a. The rotation angle of the switching lever 451 is set.

このように構成した第4実施形態では、把持部410のホース接続部414側の端部に設けられた流路切換弁440の突出部441を把持部410の外周面に沿って回動することにより浄水と原水とを切り換えることができ、また、吐出切換弁450の切換レバー451を操作することにより、浄水と原水との切換えとは独立に、ストレート吐出とシャワー吐出とを切り換えることができるようになる。
[Function and effect]
In the fourth embodiment configured as described above, the protruding portion 441 of the flow path switching valve 440 provided at the end of the gripping portion 410 on the hose connection portion 414 side is rotated along the outer peripheral surface of the gripping portion 410. It is possible to switch between purified water and raw water, and by operating the switching lever 451 of the discharge switching valve 450, it is possible to switch between straight discharge and shower discharge independently of switching between purified water and raw water. become.
いま、流路切換弁440の突出部441を操作して、図84〜86に示すように、流路切換弁440を浄水吐出位置に設定した場合、流路切換弁440の弁座側に穿設された孔442eに弁体側に穿設された孔443eの位置が同軸的に一致して、水質浄化用カートリッジ430の中央空間部432を流路切換弁440の入口側と連通した開状態にする。このとき、混合水が把持部410のホース接続部414側から把持部410内に流入し、流入した混合水が流路切換弁440の弁座側に穿設された孔442e、弁体側に穿設された孔443eおよびカートリッジ受け417の内面側の流路417bを介して水質浄化用カートリッジ430の中央空間部432に達し、この中央空間部432からフィルタ435および水質浄化材433を透過して水質を浄化しつつ外周側流路431に流出し、この外周側流路431が頭部420の空間420aと連通しているから、浄化された混合水が外周側流路431からリブ411b,…,411bの間を通り抜けて頭部420の空間420aに流出する。そして、この空間420aから集合通過部材426を介して吐出切換弁450の設定に従い、ストレート吐出流路427bまたはシャワー吐出面上流側空間420cに流入して、ストレート吐出またはシャワー吐出する。
Now, when the projection 441 of the flow path switching valve 440 is operated to set the flow path switching valve 440 to the purified water discharge position as shown in FIGS. The position of the hole 443e formed on the valve body side coincides with the hole 442e provided coaxially, and the central space portion 432 of the water purification cartridge 430 is in an open state communicating with the inlet side of the flow path switching valve 440. To do. At this time, the mixed water flows into the gripping portion 410 from the hose connection portion 414 side of the gripping portion 410, and the mixed water that has flowed into the hole 442e formed on the valve seat side of the flow path switching valve 440 and the valve body side. It reaches the central space 432 of the water purification cartridge 430 through the provided hole 443e and the flow path 417b on the inner surface side of the cartridge receiver 417, and passes through the filter 435 and the water purification material 433 from the central space 432. , And flows out to the outer peripheral side flow path 431, and the outer peripheral side flow path 431 communicates with the space 420 a of the head 420, so that the purified mixed water flows from the outer peripheral side flow path 431 to the ribs 411 b,. It passes between 411b and flows out into the space 420a of the head 420. Then, according to the setting of the discharge switching valve 450 from the space 420a via the collective passage member 426, the straight flow or the shower discharge flows into the straight discharge flow path 427b or the shower discharge surface upstream space 420c.
次に、この浄水吐出をしている場合に、流路切換弁440の突出部441を把持部410の外周面に沿い所定方向へ必要角度回動して、図90〜92に示すように、流路切換弁440を原水吐出位置に設定した場合、流路切換弁440の弁座側に穿設された孔442eに弁体側に穿設された孔443fの位置が同軸的に一致して、水質浄化用カートリッジ430の外周側流路431を流路切換弁440の入口側と連通した開状態にし、水質浄化用カートリッジ430の中央空間部432を流路切換弁440の入口側と遮断した閉状態にする。
Next, when this purified water discharge is performed, the protrusion 441 of the flow path switching valve 440 is rotated by a necessary angle in a predetermined direction along the outer peripheral surface of the gripper 410, as shown in FIGS. When the flow path switching valve 440 is set to the raw water discharge position, the position of the hole 443f drilled on the valve body side coincides with the hole 442e drilled on the valve seat side of the flow path switching valve 440, The outer flow path 431 of the water purification cartridge 430 is opened to communicate with the inlet side of the flow switching valve 440, and the central space portion 432 of the water purification cartridge 430 is closed from the inlet side of the flow switching valve 440. Put it in a state.
このときには、把持部410のホース接続側から混合水が流入してくると、流路切換弁440の弁座側に穿設された孔442e、弁体側に穿設された孔443f、およびカートリッジ受け417の外周側の流路417aを介して水質浄化用カートリッジ430の外周側流路431に流入し、混合水が浄化されずに、そのまま外周側流路431から頭部420の空間420aに流出する。そして、この空間420aから集合通過部材426を介して吐出切換弁450の設定に従いストレート吐出流路427bまたはシャワー吐出面上流側空間420cに流入して、ストレート吐出またはシャワー吐出する。
その後、流路切換弁440の突出部441を把持部410の外周面に沿って、原水吐出の場合と逆方向へ同じ角度回動すると、図84〜86に示すような浄水吐出の場合に戻り、浄水を吐出することができるようになる。
At this time, if mixed water flows in from the hose connection side of the gripper 410, the hole 442e formed on the valve seat side of the flow path switching valve 440, the hole 443f formed on the valve body side, and the cartridge receiver It flows into the outer peripheral flow path 431 of the water purification cartridge 430 through the outer peripheral flow path 417a of 417, and the mixed water flows out from the outer peripheral flow path 431 to the space 420a of the head 420 without being purified. . Then, it flows into the straight discharge flow path 427b or the shower discharge surface upstream side space 420c from the space 420a through the collective passage member 426 according to the setting of the discharge switching valve 450, and performs straight discharge or shower discharge.
Thereafter, when the protruding portion 441 of the flow path switching valve 440 is rotated along the outer peripheral surface of the gripper 410 in the opposite direction to that of the raw water discharge, it returns to the case of the clean water discharge as shown in FIGS. It becomes possible to discharge purified water.
また、吐出切換弁450の操作については、流路切換弁440の操作とは独立にでき、ストレート吐出とシャワー吐出とを任意に設定することができる。
まず、切換レバー451を操作して弁軸の軸心を中心にしてストレート吐出側に回動すると、弁体450aがストレート吐出用流路形成部材427の開口427aの位置から外れ、集合通過部材426から流出する混合水がストレート吐出用流路形成部材427の開口427aへ流入し、ストレート吐出流路427bの内部を通過してストレート吐出口422から吐出するようになる。
Further, the operation of the discharge switching valve 450 can be performed independently of the operation of the flow path switching valve 440, and straight discharge and shower discharge can be arbitrarily set.
First, when the switching lever 451 is operated and rotated to the straight discharge side about the axis of the valve shaft, the valve body 450a is disengaged from the position of the opening 427a of the straight discharge flow path forming member 427, and the collective passage member 426 is moved. The mixed water flowing out of the straight gas flows into the opening 427a of the straight discharge flow path forming member 427, passes through the straight discharge flow path 427b, and is discharged from the straight discharge port 422.
そして、切換レバー451がストレート吐出側に設定されている場合に、切換レバー451を反対方向へ操作して、弁軸の軸心を中心にしてシャワー吐出側に回動すると、図85または91に示すように、弁体450aの皿部450bがストレート吐出用流路形成部材427の開口427aの上部に位置して開口427aを塞ぎ、集合通過部材426から流出する混合水が弁体450aの皿部450bに阻まれてストレート吐出用流路形成部材427の周囲に流出し、仕切部材425とシャワープレート421によって形成されたシャワー吐出面上流側空間420cを介してシャワー吐出口423から吐出するようになる。
その後、切換レバー451を操作して弁軸の軸心を中心にしてストレート吐出側に回動すると、前述のように、ストレート吐出口422から吐出するようになる。
Then, when the switching lever 451 is set to the straight discharge side, when the switching lever 451 is operated in the opposite direction and rotated to the shower discharge side around the axis of the valve shaft, FIG. As shown, the dish portion 450b of the valve body 450a is positioned above the opening 427a of the straight discharge flow path forming member 427, closes the opening 427a, and the mixed water flowing out from the collective passage member 426 is the dish portion of the valve body 450a. It is blocked by 450 b and flows out around the straight discharge flow path forming member 427, and is discharged from the shower discharge port 423 through the shower discharge surface upstream space 420 c formed by the partition member 425 and the shower plate 421. .
Thereafter, when the switching lever 451 is operated to rotate to the straight discharge side around the axis of the valve shaft, the discharge is made from the straight discharge port 422 as described above.
これにより、流路切換弁440の突出部441を把持部410の中心軸回りかつ外周面に沿って回動することにより、浄水吐出と原水吐出とを容易に切り換えることができ、浄水吐出時には、混合水が水質浄化用カートリッジ430の中央空間部432から外周側流路431へと、水質浄化材433を通過する際に浄化されるようになる。
これに加えて、吐出切換弁450が流路切換弁440と完全に独立しているため、原水と浄水のどちらが吐出される場合であっても、ストレート吐出またはシャワー吐出のいずれかを選択して吐出させることができ、4種類の利用可能な形態が選択できるようになる。
Thereby, by rotating the protrusion 441 of the flow path switching valve 440 around the central axis of the gripper 410 and along the outer peripheral surface, it is possible to easily switch between purified water discharge and raw water discharge. The mixed water is purified when it passes through the water purification material 433 from the central space 432 of the water purification cartridge 430 to the outer peripheral flow path 431.
In addition, since the discharge switching valve 450 is completely independent of the flow path switching valve 440, either straight discharge or shower discharge is selected regardless of whether raw water or purified water is discharged. It can be discharged and four types of available forms can be selected.
