内側管部514は、大径管部513の内側において、上下方向に延びる筒状に形成される。内側管部514の内側には、電磁弁34から排出される水を上方側から下方側に流通させるボディ側第4流路F4が形成される。 The inner pipe portion 514 is formed in a tubular shape extending in the vertical direction inside the large diameter pipe portion 513. Inside the inner pipe portion 514, a body-side fourth flow path F4 that allows water discharged from the solenoid valve 34 to flow from the upper side to the lower side is formed.

ボディ側導出横管部515は、内側管部514の上下方向の下方側に接続され、水平方向の一方側に延びて形成される。ボディ側導出横管部515の水平方向における内側管部514と反対側の一方側の端部には、第2開口515aが形成される。第2開口515aは、電磁弁ボディ部60が金型を用いた樹脂材料で形成されていることにより、金型を用いた樹脂材料の成形時において電磁弁ボディ部60の側方にアンダーカットとして形成された開口である。 The body side lead-out horizontal pipe portion 515 is connected to the lower side in the vertical direction of the inner pipe portion 514 and is formed so as to extend to one side in the horizontal direction. A second opening 515a is formed at one end of the horizontal tube portion 515 on the body side, which is opposite to the inner tube portion 514 in the horizontal direction. Since the solenoid valve body portion 60 is formed of the resin material using the mold, the second opening 515a serves as an undercut on the side of the solenoid valve body portion 60 when the resin material is molded using the mold. It is an opening formed.

第2開口515aには、図5及び図6に示すように、第2開口515aを塞ぐ第2キャップ部502が取り付けられる。これにより、第2開口515aは、第2キャップ部502で塞がれる。第2キャップ部502には、上下方向に延びる板状突出部502aが形成される。第2キャップ部502は、第1キャップ部501により保持される。 As shown in FIGS. 5 and 6, a second cap portion 502 that closes the second opening 515a is attached to the second opening 515a. As a result, the second opening 515a is closed by the second cap portion 502. The second cap portion 502 is formed with a plate-shaped protruding portion 502a extending in the vertical direction. The second cap portion 502 is held by the first cap portion 501.

The plate-shaped protrusion 502a is fitted. In this state, by fixing the first cap portion 501 to the body side flow path constituent portion 50 by screwing, the second cap portion 502 closes the second opening 515a and the first cap portion 501 closes the first opening 512b. In the closed state, the first cap portion 501 is fixed in a state where the second cap portion 502 is held down.

本実施形態においては、電磁弁ボディ部60の成形時において製造上のバラツキにより第1開口512b及び第2開口515aの位置がズレることを考慮して、第1開口512b及び第2開口515aを別々のキャップで構成することで、止水性能を確保している。なお、本実施形態においては、第1開口512b及び第2開口515aを別々のキャップで塞ぐように構成したが、これに限定されず、第1開口512b及び第2開口515aを1つのキャップで塞ぐように構成してもよい。また、第1キャップ部501及び第2キャップ部502は、ネジ止めで固定することに限定されず、例えば、溶着により接合してもよい。 In the present embodiment, the first opening 512b and the second opening 515a are separately separated in consideration of the fact that the positions of the first opening 512b and the second opening 515a are displaced due to manufacturing variations during molding of the solenoid valve body portion 60. Water-stopping performance is ensured by configuring with the cap of. In the present embodiment, the first opening 512b and the second opening 515a are configured to be closed by separate caps, but the present invention is not limited to this, and the first opening 512b and the second opening 515a are closed by one cap.

The erection guide wall 54 allows water that has been moved downward inside the cover member 31 (water leakage due to deterioration of the O-ring or water leakage when the spout 321 is closed) to the front of the faucet body 3. A guide portion for guiding to the intermediate semicircular guide plate portion 53 on the side is configured.

立設ガイド壁54には、図4に示すように、第2ハーネス302を通すためのガイド壁側スリット溝541(スリット溝、ハーネス保持部)が形成される。ガイド壁側スリット溝541は、立設ガイド壁54における上下方向の途中の位置において、水栓本体3の前後方向に直交する左右方向における一方側から他方側の途中までスリット状に延びて切り欠かれている。ガイド壁側スリット溝541には、図4に示すように、第2ハーネス302が通される。ガイド壁側スリット溝541は、第2ハーネス302を保持する。 As shown in FIG. 4, the vertical guide wall 54 is formed with a guide wall-side slit groove 541 (slit groove, harness holding portion) for passing the second harness 302. The guide wall side slit groove 541 extends in a slit shape from one side to the middle of the other side in the left-right direction orthogonal to the front-rear direction of the faucet body 3 at a position in the middle of the vertical direction on the vertical guide wall 54.

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 has a first-direction flow path (body-side first flow path F1, body-side third flow path) in which water flows from the lower side to the upper side. F3, body side 6th flow path F6), 2nd direction flow path (body side 4th flow path F4) where water flows from the upper side to the lower side, and water flows from one side to the other side in the horizontal direction. A third-direction flow path (second body-side flow path F2) and a fourth-direction flow path (fifth flow path F5 on the body side) through which water flows from the other side to 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 the present embodiment, since the body of the faucet body 3 is configured to extend in the vertical direction, it is required to form the body of the faucet body 3 compactly in the lateral direction. Therefore, in the present embodiment, the solenoid valve 34 is arranged in the connecting cylinder portion 61 at the upper end of the solenoid valve body portion 60 so that water introduced from the lower side is guided to the upper side through the solenoid valve 34. By forming a flow path in which a plurality of flow paths in different directions are combined in the body side flow path component 50, the body of the faucet body 3 is compactly formed in the lateral direction. In the present embodiment, the solenoid valve 34 is arranged on the upper side of the solenoid valve body portion 60, and the solenoid valve body portion 60 including the body side flow path constituent portion 50 is integrally formed of a resin material in different directions. By forming a plurality of flow paths, it is possible to form the body of the faucet body 3 compactly 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 main body 3 of the present embodiment, according to FIGS. 3 and 4, water moved downward inside the cover member 31 (when water leakage due to deterioration of the O-ring or the spout 321 is blocked). The flow of leaked water) 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 inside the cover member 31 (water leaked due to deterioration of the O-ring or water leaked when the spout 321 is closed) is collected in the erecting guide wall 54 in the flow path component main body 51. Guided by (see FIG. 4), it is guided to the intermediate semicircular guide plate portion 53. The water guided to the intermediate semicircle guide plate portion 53 moves outward in the radial direction of the intermediate semicircle 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 protrusion plate 44 on the outside of the peripheral wall portion 43. The water that has flowed into the upper surface of the radial annular protrusion plate 44 flows circumferentially through the upper surface of the radial annular protrusion plate 44 between the inner peripheral surface of the cover member 31 and the outer peripheral surface of the peripheral wall portion 43, and is a faucet. It is discharged to the outside through the drain hole 311b (see FIG. 3) on the rear side of the main body 3. As a result, water can be discharged to the upper surface of the upper surface plate 112 of the wash basin 11, so that it is possible to prevent the water from flowing out below the wash basin 11. Thereby, the drainage performance of the faucet main 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 main body 3 configured as described above, the cover member 31 is detachably configured with respect to the mounting legs 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 main body 3 of the present embodiment, as shown in FIG. 8, the cover member 31 is open downward and is attached to the peripheral edge of the pedestal portion 41 of the attachment leg 40. Therefore, by moving the cover member 31 in the vertical direction, the cover member 31 is attached to and detached from the pedestal portion 41 of the mounting leg 40. Therefore, the attachment / detachment 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。 Further, the lower portion of the water discharge portion side introduction vertical pipe portion 331 of the water discharge portion side flow path constituent portion 33 is open downward, and the body side lead-out vertical pipe portion 516 of the body side flow path constituent portion 50 is upward. Extends to. Therefore, by moving the water discharge part side introduction vertical pipe part 331 of the water discharge part side flow path component 33 in the vertical direction, the water discharge part side introduction vertical pipe part 331 of the water discharge part side flow path component 33 can flow to the body side. It is attached to and detached from the body-side lead-out vertical pipe portion 516 of the road constituent portion 50. Therefore, the attachment / detachment direction of the body side flow path constituent portion 50 with respect to the water discharge portion side flow path constituent portion 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 constituent portion 50 with respect to the water discharge portion side flow path constituent portion 33 are both vertical directions and attachment / detachment. The directions match.

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 the cover member 31 is removed 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 constituent portion 50 with respect to the water discharge portion side flow path constituent portion 33. Since the directions match, simply by moving the cover member 31 upward, the water discharge part side introduction vertical pipe of the water discharge part side flow path component 33 from the body side lead-out vertical pipe part 516 of the body side flow path component 50 By removing the portion 331, the flow path arranged inside the cover member 31 can be divided, and the cover member 31 can be easily removed from the mounting leg 40.
