The mounting portion 332 is provided with a rectangular parallelepiped recess 3321 having a shape complementary to the connecting portion 3153 of the transmission member 315. A connecting portion 3153 is fitted in the recess 3321. Further, a protrusion 3322 is provided on the inner surface of the recess 3321. The protrusion 3322 fits into the groove 3153a of the transmission member 315.
　ハウジング３１１内には、カラー３１６が取り付けられた伝達部材３１５、可動ディスク３１４、固定ディスク３１２の順で収容される。カバー３１３は、固定ディスク３１２の第一面３１２Ａ側に被せられる。そして、カバー３１３の爪部３１３２を、ハウジング３１１の開口部３１１１ａに係止させることで、切替ユニット３１が完成する。 The transmission member 315 to which the collar 316 is attached, the movable disc 314, and the fixed disc 312 are housed in the housing 311 in this order. The cover 313 is put on the first surface 312A side of the fixed disc 312. Then, the switching unit 31 is completed by locking the claw portion 3132 of the cover 313 to the opening 3111a of the housing 311.
　切替ユニット３１は、カバー３１３が本体部２側となるように、収容部２１内に収容される。そして、押さえナット３２を収容部２１に螺合させることにより、切替ユニット３１は本体部２に固定される。レバー３３の凹部３３２１内に、伝達部材３１５の接続部３１５３を挿入し、レバー３３の突起部３３２２を、接続部３１５３の溝３１５３ａに嵌合させることにより、レバー３３は伝達部材３１５に取り付けられる。突起部３３２２が、伝達部材３１５の溝３１５３ａに嵌合しているため、レバー３３は、軸方向に引っ張っても、伝達部材３１５から抜けないようになっている。 The switching unit 31 is accommodated in the accommodating portion 21 so that the cover 313 is on the main body portion 2 side. Then, by screwing the pressing nut 32 into the accommodating portion 21, the switching unit 31 is fixed to the main body portion 2. The lever 33 is attached to the transmission member 315 by inserting the connection portion 3153 of the transmission member 315 into the recess 3321 of the lever 33 and fitting the protrusion 3322 of the lever 33 into the groove 3153a of the connection portion 3153. Since the protrusion 3322 is fitted in the groove 3153a of the transmission member 315, the lever 33 does not come off from the transmission member 315 even if it is pulled in the axial direction.
　レバー３３を回転させることにより、伝達部材３１５も回転する。伝達部材３１５の突起部３１５１ａは、可動ディスク３１４の切欠き３１４１に嵌合しているため、伝達部材３１５の回転に伴い、可動ディスク３１４も回転する。可動ディスク３１４は、その第一面３１４Ａが、固定ディスク３１２の第二面３１２Ｂに摺動しながら回転する。固定ディスク３１２は、カバー３１３と共にハウジング３１１に固定されているため、可動ディスク３１４が回転したとしても、固定ディスク３１２は回転しない。 By rotating the lever 33, the transmission member 315 also rotates. Since the protrusion 3151a of the transmission member 315 is fitted in the notch 3141 of the movable disk 314, the movable disk 314 also rotates as the transmission member 315 rotates. The movable disc 314 rotates while its first surface 314A slides on the second surface 312B of the fixed disc 312. Since the fixed disc 312 is fixed to the housing 311 together with the cover 313, the fixed disc 312 does not rotate even if the movable disc 314 rotates.

Inflow. The raw water flows in the raw water guide path 3142 from one end to the other end. After that, the raw water flows from the raw water guide path 3142 of the movable disk 314 into one end of the straight water guide path 3126 of the fixed disk 312, and enters the straight water guide path 3126 from one end to the other end. It flows toward. Then, the raw water flows out from the straight water outlet 3125, passes through the straight water supply path P4, and is discharged as straight water from the straight water discharge port 24, as shown in FIG. 10 (b).
　図１１（ａ）に示すように、可動ディスク３１４がストレート水吐出位置にあるとき、固定ディスク３１２のシャワー水用案内路３１２４及びシャワー水用流出口３１２３は、可動ディスク３１４の原水案内路３１４２と連通していない。したがって、可動ディスク３１４がストレート水吐出位置にあるとき、シャワー水吐出口２３から、シャワー水が吐出されることはない。 As shown in FIG. 11A, when the movable disk 314 is in the straight water discharge position, the shower water guide path 3124 and the shower water outlet 3123 of the fixed disk 312 are connected to the raw water guide path 3142 of the movable disk 314. There is no communication. Therefore, when the movable disc 314 is in the straight water discharge position, the shower water is not discharged from the shower water discharge port 23.
　図１１（ｂ）に示すように、可動ディスク３１４がストレート水吐出位置にあるとき、固定ディスク３１２の浄水案内路３１２８は、可動ディスク３１４の第一面３１４Ａの平面部分に相対する。したがって、浄水導入路Ｐ２を通過した浄水は、固定ディスク３１２の浄水流入口３１２７に流入し、浄水案内路３１２８に進入した後、可動ディスク３１４の平面部分によってせき止められる。これにより、可動ディスク３１４がストレート水吐出位置にあるとき、浄水が、浄水吐出口２７から吐出されることはない。 As shown in FIG. 11B, when the movable disc 314 is in the straight water discharge position, the water purification guide path 3128 of the fixed disc 312 faces the flat surface portion of the first surface 314A of the movable disc 314. Therefore, the purified water that has passed through the water purification introduction path P2 flows into the purified water inlet 3127 of the fixed disk 312, enters the water purification guide path 3128, and is then dammed by the flat surface portion of the movable disk 314. As a result, when the movable disk 314 is in the straight water discharge position, the purified water is not discharged from the purified water discharge port 27.
＜５　浄水吐出モード＞
　図１２及び図１３を参照して、浄水吐出口２７から、浄水が吐出される場合について説明する。 <5 Purified water discharge mode>
A case where purified water is discharged from the purified water discharge port 27 will be described with reference to FIGS. 12 and 13.
　使用者がレバー３３を操作して可動ディスク３１４を回転させ、図１３（ａ）に示すように、固定ディスク３１２の浄水案内路３１２８及び浄水流出口３１２９が、可動ディスク３１４の浄水案内路３１４３と連通するように、可動ディスク３１４の位置を切り替える。 The user operates the lever 33 to rotate the movable disk 314, and as shown in FIG. 13A, the water purification guide path 3128 and the water purification outlet 3129 of the fixed disk 312 are connected to the water purification guide path 3143 of the movable disk 314. The position of the movable disk 314 is switched so as to communicate with each other.
　図１２（ｂ）及び図１３（ａ）に示すように、浄水器Ｘから浄水入口２６に流入した浄水は、浄水導入路Ｐ２を通り、浄水流入口３１２７に流入する。浄水は、浄水流入口３１２７を通過し、固定ディスク３１２の浄水案内路３１２８内を、その一端部から他端部に向けて流れる。その後、浄水は、固定ディスク３１２の浄水案内路３１２８から、可動ディスク３１４の浄水案内路３１４３内に流入し、浄水案内路３１４３内を、その一端部から他端部に向けて流れる。そして、浄水は、浄水流出口３１２９から流出し、図１２（ｃ）に示すように、浄水用供給路Ｐ５を通って、浄水吐出口２７から吐出される。 As shown in FIGS. 12 (b) and 13 (a), the purified water flowing from the water purifier X into the water purification inlet 26 passes through the water purification introduction path P2 and flows into the water purification inflow inlet 3127. The purified water passes through the purified water inflow port 3127 and flows through the purified water guide path 3128 of the fixed disk 312 from one end to the other end. After that, the purified water flows from the water purification guide path 3128 of the fixed disk 312 into the water purification guide path 3143 of the movable disk 314, and flows through the water purification guide path 3143 from one end to the other end. Then, the purified water flows out from the purified water outlet 3129, and as shown in FIG. 12 (c), is discharged from the purified water discharge port 27 through the water purification supply path P5.
　図１３（ｂ）に示すように、可動ディスク３１４が浄水吐出位置にあるとき、固定ディスク３１２の原水流入口３１２２は、可動ディスク３１４の第二面３１４Ａの平面部分に相対する。したがって、切替機構３に到達した原水は、固定ディスク３１２の原水流入口３１２２に流入するが、可動ディスク３１４によってせき止められる。これにより、可動ディスク３１４が浄水吐出位置にあるとき、原水が、シャワー水吐出口２３、又はストレート水吐出口２４から吐出されることはない。 As shown in FIG. 13B, when the movable disk 314 is in the purified water discharge position, the raw water inflow port 3122 of the fixed disk 312 faces the flat surface portion of the second surface 314A of the movable disk 314. Therefore, the raw water that has reached the switching mechanism 3 flows into the raw water inflow port 3122 of the fixed disk 312, but is dammed by the movable disk 314. As a result, when the movable disk 314 is in the purified water discharge position, the raw water is not discharged from the shower water discharge port 23 or the straight water discharge port 24.
＜６　特徴＞
　本発明の切替装置１では、固定ディスク３１２と可動ディスク３１４の二枚のセラミックスディスクによって、シャワー水吐出モード、ストレート水吐出モード、及び浄水吐出モードを切り替えることができる。したがって、高価なセラミックスディスクの枚数を減らすことができるため、コストを低下させることができる。また、吐出モードの切替に関与するセラミックスディスクが二枚になることで、ディスク同士が摺動する際の摩擦力が減り、操作トルクを小さくすることができる。 <6 Features>
