ここで、ボディ側流路構成部50には、異なる方向の2方向以上に延びる複数の流路が形成されている。ボディ側流路構成部50には、図3及び図7に示すように、下方側から上方側に水が流通する第1方向流路(ボディ側第1流路F1、ボディ側第3流路F3、ボディ側第6流路F6)と、上方側から下方側に水が流通する第2方向流路(ボディ側第4流路F4)と、水平方向において一方側から他方側に水が流通する第3方向流路(ボディ側第2流路F2)と、水平方向において他方側から一方側に水が流通する第4方向流路(ボディ側第5流路F5)と、が形成される。第1方向流路、第2方向流路、第3方向流路及び第4方向流路は、それぞれ異なる方向の流路である。   Here, the body-side flow path component 50 is formed with a plurality of flow paths extending in two or more directions in different directions. As shown in FIGS. 3 and 7, the body-side flow path component 50 includes a first direction flow path (body-side first flow path F1, body-side third flow path) through which water flows from the lower side to the upper side. F3, body side sixth flow path F6), second direction flow path (body side fourth flow path F4) through which water flows from the upper side to the lower side, and water flows from one side to the other side in the horizontal direction. Third direction flow path (body-side second flow path F2) and a fourth direction flow path (body-side fifth flow path F5) through which water flows from the other side to the one side in the horizontal direction are formed. . The first direction flow path, the second direction flow path, the third direction flow path, and the fourth direction flow path are flow paths in different directions.

本実施形態においては、水栓本体3の胴体が上下方向に延びるように構成されるため、水栓本体3の胴体を横方向においてコンパクトに形成することが求められる。そのため、本実施形態では、電磁弁34を電磁弁ボディ部60の上端部の連結筒部61に配置して、下方側から導入された水を電磁弁34を通らせて上方側に導くように、ボディ側流路構成部50において複数の異なる方向の流路を組み合わせた流路を形成することで、水栓本体3の胴体を横方向にコンパクトに形成する。本実施形態では、電磁弁34を電磁弁ボディ部60の上方側に配置して、ボディ側流路構成部50を含む電磁弁ボディ部60を樹脂材料で一体に形成することで、異なる方向の複数の流路を形成して、水栓本体3の胴体を横方向にコンパクトに形成することを実現している。   In this embodiment, since the trunk of the faucet body 3 is configured to extend in the vertical direction, it is required to form the trunk of the faucet body 3 compactly in the lateral direction. Therefore, in this embodiment, the electromagnetic valve 34 is disposed in the connecting cylinder portion 61 at the upper end of the electromagnetic valve body portion 60 so that the water introduced from the lower side passes through the electromagnetic valve 34 and is guided upward. In addition, the body of the faucet body 3 is compactly formed in the lateral direction by forming a flow path in which a plurality of flow paths in different directions are combined in the body-side flow path constituting unit 50. In the present embodiment, the electromagnetic valve 34 is disposed on the upper side of the electromagnetic valve body 60, and the electromagnetic valve body 60 including the body-side flow path component 50 is integrally formed of a resin material, so that different directions are obtained. A plurality of flow paths are formed, and the body of the faucet body 3 is formed compact in the lateral direction.

次に、本実施形態の水栓本体3において、図3及び図4により、カバー部材31の内部を下方側に移動された水(Oリングの劣化による漏水や吐水口321が塞がれたときの漏水の水)の流れについて説明する。   Next, in the faucet body 3 of the present embodiment, the water moved downward in the cover member 31 according to FIGS. 3 and 4 (when water leaks due to deterioration of the O-ring or the water discharge port 321 is blocked) Will be described.

カバー部材31の内部を下方側に移動された水(Oリングの劣化による漏水や吐水口321が塞がれたときの漏水の水)は、流路構成部本体51において、立設ガイド壁54(図4参照)にガイドされて、中間半円ガイド板部53に導かれる。中間半円ガイド板部53に導かれた水は、中間半円ガイド板部53の径方向の外側に移動して、周壁部43の外側に導かれる。周壁部43の外側に導かれた水は、周壁部43の外側において、径方向環状突出板44の上面に流れ込む。径方向環状突出板44の上面に流れ込んだ水は、カバー部材31の内周面と周壁部43の外周面との間において、径方向環状突出板44の上面を周方向に流れて、水栓本体3の後方側の水抜き穴311b(図3参照)から外部に排出される。これにより、洗面器11の上面板112の上面に水を排出することができるため、洗面器11の下方へ水が流れ出ることを抑制できる。これにより、水栓本体3の排水性能を向上させることができる。   The water moved downward in the cover member 31 (water leakage due to deterioration of the O-ring or water leaked when the water discharge port 321 is blocked) in the flow path component main body 51 is a standing guide wall 54. (See FIG. 4) and guided to the intermediate semicircular guide plate portion 53. The water guided to the intermediate semicircular guide plate portion 53 moves to the outside in the radial direction of the intermediate semicircular guide plate portion 53 and is guided to the outside of the peripheral wall portion 43. The water guided to the outside of the peripheral wall portion 43 flows into the upper surface of the radial annular projecting plate 44 outside the peripheral wall portion 43. The water that has flowed into the upper surface of the radial annular projecting plate 44 flows between the inner peripheral surface of the cover member 31 and the outer peripheral surface of the peripheral wall portion 43 in the circumferential direction on the upper surface of the radial annular projecting plate 44. The water is discharged to the outside through a drain hole 311b (see FIG. 3) on the rear side of the main body 3. Thereby, since water can be discharged | emitted to the upper surface of the upper surface board 112 of the washbasin 11, it can suppress that water flows out below the washbasin 11. FIG. Thereby, the drainage performance of the faucet body 3 can be improved.

また、以上のように構成される水栓本体3において、取付脚40に対してカバー部材31は着脱可能に構成される。この構成について詳細に説明する。   Further, in the faucet body 3 configured as described above, the cover member 31 is configured to be detachable from the mounting leg 40. This configuration will be described in detail.

本実施形態の水栓本体3においては、図8に示すように、カバー部材31は、下方に向けて開口しており、取付脚40の台座部41の周縁に取り付けられる。そのため、カバー部材31を上下方向に移動させることで、カバー部材31は、取付脚40の台座部41に着脱される。よって、取付脚40に対するカバー部材31の着脱方向は上下方向である。   In the faucet body 3 of the present embodiment, as shown in FIG. 8, the cover member 31 opens downward and is attached to the periphery of the pedestal portion 41 of the attachment leg 40. Therefore, the cover member 31 is attached to and detached from the pedestal portion 41 of the mounting leg 40 by moving the cover member 31 in the vertical direction. Therefore, the attaching / detaching direction of the cover member 31 with respect to the mounting leg 40 is the vertical direction.

また、吐水部側流路構成部33の吐水部側導入縦管部331の下部は、下方に向けて開口しており、ボディ側流路構成部50のボディ側導出縦管部516は、上方に延びている。そのため、吐水部側流路構成部33の吐水部側導入縦管部331を上下方向に移動させることで、吐水部側流路構成部33の吐水部側導入縦管部331は、ボディ側流路構成部50のボディ側導出縦管部516に着脱される。よって、吐水部側流路構成部33に対するボディ側流路構成部50の着脱方向は上下方向である。   Moreover, the lower part of the water discharge part side introduction vertical pipe part 331 of the water discharge part side flow path structure part 33 is opened downward, and the body side outlet vertical pipe part 516 of the body side flow path structure part 50 is upward. It extends to. Therefore, the water discharge part side introduction vertical pipe part 331 of the water discharge part side flow path structure part 33 moves the body side stream by moving the water discharge part side introduction vertical pipe part 331 of the water discharge part side flow path structure part 33 in the vertical direction. It is attached to and detached from the body side outlet vertical pipe portion 516 of the path constituting portion 50. Therefore, the attachment / detachment direction of the body-side flow path component 50 with respect to the water discharger-side flow path component 33 is the vertical direction.

以上により、本実施形態においては、取付脚40に対するカバー部材31の着脱方向と、吐水部側流路構成部33に対するボディ側流路構成部50の着脱方向とは、共に上下方向であり、着脱方向が一致する。   As described above, in the present embodiment, the attachment / detachment direction of the cover member 31 with respect to the mounting leg 40 and the attachment / detachment direction of the body-side flow path component 50 with respect to the water discharger-side flow path component 33 are both vertical directions. The direction matches.

取付脚40からカバー部材31を取り外す場合には、図8に示すように、取付脚40に対するカバー部材31の着脱方向と、吐水部側流路構成部33に対するボディ側流路構成部50の着脱方向とが一致するため、カバー部材31を上方側へ移動させるだけで、ボディ側流路構成部50のボディ側導出縦管部516から吐水部側流路構成部33の吐水部側導入縦管部331が外れることにより、カバー部材31の内部に配置される流路を分断させて、取付脚40からカバー部材31を容易に取り外すことができる。なお、本実施形態においては、第1ハーネス301及び第2ハーネス302は、取付脚40からカバー部材31を取り外してカバー部材31を上方側に移動させることを考慮して、余分に長く形成されており、カバー部材31が取付脚40に取り付けられている時には、カバー部材31の内部に収容されている。   When removing the cover member 31 from the mounting leg 40, as shown in FIG. 8, the attachment / detachment direction of the cover member 31 with respect to the mounting leg 40, and the attachment / detachment of the body side flow path component 50 with respect to the water discharger flow path component 33. Since the directions coincide with each other, simply by moving the cover member 31 upward, the water discharge portion side introduction vertical tube of the water discharge portion side flow passage configuration portion 33 from the body side outlet vertical tube portion 516 of the body side flow passage constitution portion 50 is obtained. When the portion 331 is detached, the flow path disposed inside the cover member 31 is divided, and the cover member 31 can be easily detached from the mounting leg 40. In the present embodiment, the first harness 301 and the second harness 302 are formed to be excessively long in consideration of removing the cover member 31 from the mounting leg 40 and moving the cover member 31 upward. When the cover member 31 is attached to the mounting leg 40, the cover member 31 is accommodated inside the cover member 31.

取付脚40からカバー部材31を取り外した状態においては、図8に示すように、ボディ側流路構成部50のボディ側導出縦管部516から吐水部側流路構成部33の吐水部側導入縦管部331が外れた状態であり、カバー部材31側には、吐水部32、吐水部側流路構成部33、センサ部35及び回路ユニット36が配置され、取付脚40側には、電磁弁34及び電磁弁ボディ部60(ボディ側流路構成部50)が配置される。このように、取付脚40からカバー部材31を取り外した状態においては、電磁弁34が取付脚40側に残されるため、電磁弁34を交換するなどのメンテナンスを容易に行うことができる。   In a state where the cover member 31 is removed from the mounting leg 40, as shown in FIG. 8, the water discharger side introduction of the water discharger side flow path component 33 from the body side outlet vertical pipe part 516 of the body side flow path component 50.
