この部分の部材の分解図を図2に示し、さらに図3には部材を拡大して示す。さらに図4では部材の取付状態の縦断面図を示す。
A drainage device 9 shown in FIG. 2 is attached from the back side of the drainage hole 3c of the wash bowl 3, and a hair catcher portion 7 shown in FIG. 2 is arranged in the drainage device 9 so that it can be pulled up and down from the drainage hole 3c side. Moreover, the pop-up valve 6 is arrange | positioned so that opening and closing is possible in the drain hole 3c.
FIG. 2 shows an exploded view of the member in this portion, and FIG. 3 shows the member in an enlarged manner. Furthermore, in FIG. 4, the longitudinal cross-sectional view of the attachment state of a member is shown.

洗面ボウルのボウル部3aの裏側から、排水器具9が排水孔3cの真下に同芯状に取付け固定されるものであり、排水器具9の下端の接続部17aには、袋ナット13を介してレリース保持部材10が連結され、さらに、このレリース保持部材10の下端側に、袋ナット14を介してキャビネット2内に縦方向に配管されるトラップ管15が接続されるものである。
レリース保持部材10には、一体状に傾斜して傾斜筒部10aが形成されており、この傾斜筒部10a内に、前記操作ボタン5に上端を連結したレリース11の下端側の先端部11aが配置されて、このレリースの先端部11aは、上下方向に揺動可能に設けられた揺動部材12に連結されている。
From the back side of the bowl portion 3a of the wash bowl, the drainage device 9 is attached and fixed concentrically directly below the drainage hole 3c. A release holding member 10 is connected, and a trap pipe 15 piped in the vertical direction in the cabinet 2 is connected to the lower end side of the release holding member 10 via a cap nut 14.
The release holding member 10 is formed with an inclined cylinder portion 10a that is integrally inclined, and a tip end portion 11a on the lower end side of the release 11 having the upper end connected to the operation button 5 is formed in the inclined cylinder portion 10a. The tip 11a of the release is connected to a swing member 12 that is swingable in the vertical direction.

なお、操作ボタン部5は、洗面ボウルのバックガード部3bに固定部5aを固定して取り付けられるものであり、操作ボタン部5を図4の状態から、手で操作することにより、レリース11の先端部11aを介して揺動部材12が上方側へ揺動し、軸部6aの下端を上方へ押し上げ、これにより、排水孔3cに当接されているポップアップ弁6が上方へ移動されて排水孔3cが開かれるように構成されている。   The operation button portion 5 is attached by fixing the fixing portion 5a to the back guard portion 3b of the wash bowl. By operating the operation button portion 5 by hand from the state shown in FIG. The swing member 12 swings upward via the tip portion 11a and pushes the lower end of the shaft portion 6a upward. As a result, the pop-up valve 6 in contact with the drain hole 3c is moved upward and drained. The hole 3c is configured to be opened.

なお、ポップアップ弁6の下面中央部から垂下状に軸部6aが一体形成されており、この軸部6aには、ヘアキャッチャー部7とオーバーフローキャッチャー8が一体状に取り付けられている。従って、ポップアップ弁6の上昇とともにヘアキャッチャー部7およびオーバーフローキャッチャー8も同時に上方へ移動されることとなり、ポップアップ弁6を摘んで上方へ引き上げることにより、ヘアキャッチャー部7およびオーバーフローキャッチャー8をボウル部3aの上方へ取り出すことができるものである。   A shaft portion 6a is integrally formed so as to hang from the center of the lower surface of the pop-up valve 6. A hair catcher portion 7 and an overflow catcher 8 are integrally attached to the shaft portion 6a. Accordingly, as the pop-up valve 6 rises, the hair catcher portion 7 and the overflow catcher 8 are simultaneously moved upward. By picking up the pop-up valve 6 and pulling it upward, the hair catcher portion 7 and the overflow catcher 8 are moved to the bowl portion 3a. It can be taken out above.

前記排水器具9は、縦方向に延びる円筒状の本体筒部16の下端側が縮径された縮径部17となっており、この縮径部17の下端側に接続部17aが形成され、この接続部17aの外周の雄ネジに袋ナット13を締め付けて、前記レリース保持部材10を取り付けできるものである。
また、排水器具9の本体筒部16の上端には、略水平方向に外側へ一体状に延びる止水鍔部18が形成されている。
また、この止水鍔部18の下方に、本体筒部16から横方向に一体状に突出したオーバーフローホース接続部19が形成されている。このオーバーフローホース接続部19には、袋ナット20を介してオーバーフローホース21を接続することができ、オーバーフローホース21を通りボウル部3a内のオーバーフロー水が排水器具9内に流入されるように構成されている。
The drainage device 9 is a reduced diameter portion 17 in which the lower end side of a cylindrical main body cylinder portion 16 extending in the vertical direction is reduced in diameter, and a connecting portion 17a is formed on the lower end side of the reduced diameter portion 17, The release holding member 10 can be attached by tightening the cap nut 13 on the male screw on the outer periphery of the connecting portion 17a.
Further, a waterstop portion 18 that extends integrally outward in a substantially horizontal direction is formed at the upper end of the main body cylinder portion 16 of the drainage device 9.
Further, an overflow hose connection portion 19 that protrudes integrally from the main body cylinder portion 16 in the lateral direction is formed below the waterstop portion 18. An overflow hose 21 can be connected to the overflow hose connection portion 19 via a cap nut 20, and the overflow water in the bowl portion 3 a flows into the drainage device 9 through the overflow hose 21. ing.

排水器具9の本体筒部16の内周面16aの内径寸法は、例えば直径63mmに設定されており、洗面ボウル3の排水孔3cの孔径61mmよりも大径に設定されている。この内周面16aには周方向に間隔をおいて3個〜6個のリブ16b,16b,16bが内側へ1mm程度突出して、それぞれ縦方向に形成されている。   The inner diameter of the inner peripheral surface 16 a of the main body cylinder portion 16 of the drainage device 9 is set to, for example, a diameter of 63 mm, and is set to be larger than the diameter of the drainage hole 3 c of the wash bowl 3. On the inner peripheral surface 16a, three to six ribs 16b, 16b, 16b are protruded inward by about 1 mm at intervals in the circumferential direction, and are respectively formed in the vertical direction.

また、止水鍔部18には、リング状に凹ませてOリング溝18aが形成されており、このOリング溝18a内にはOリングOを嵌め込むことができる。このOリング溝18aの外側の止水鍔部18に、周方向に間隔をおいて複数のビス挿通孔18b,18b,18bがそれぞれ上下に貫通形成されている。また、止水鍔部18のOリング溝18aの外側には、上方へ突出する凸部18c,18c,18cが形成されており、この凸部18c,18c,18cは、排水孔3cの軸線および本体筒部16の軸線に対し非点対称となる位置に3個以上形成され、本例では、図示上方側に1個の凸部18cが形成され、図示下方側に2個の凸部18c,18cが形成されている。   The waterstop 18 is recessed in a ring shape to form an O-ring groove 18a, and the O-ring O can be fitted into the O-ring groove 18a. A plurality of screw insertion holes 18b, 18b, 18b are vertically formed through the waterstop portion 18 outside the O-ring groove 18a at intervals in the circumferential direction. Further, convex portions 18c, 18c, and 18c projecting upward are formed on the outer side of the O-ring groove 18a of the waterstop portion 18, and the convex portions 18c, 18c, and 18c are connected to the axis of the drain hole 3c and Three or more are formed at positions that are asymmetric with respect to the axis of the main body cylindrical portion 16, and in this example, one convex portion 18c is formed on the upper side in the figure, and two convex portions 18c, 18c is formed.

なお、この3個の凸部18c,18c,18cと整合するボウル部3aの裏面位置には、3個の凹部22,22,22が排水孔3cの外周に形成されている。
また、ボウル部3aの排水孔3cの外周には、前記排水器具9の各ビス挿通孔18bと整合する位置に複数の下穴23,23,23が予め形成されている。このボウル部3aの裏側に形成される下穴23,23,23は、ボウル部3aの成形時に形成されるため、各下穴23は成形上、同方向に傾斜状に形成されている。
なお、この下穴23は、直径3mmまたは4mmまたは5mmのビス24をネジを切りながら締め付けることができる径に設定されている。また、前記排水器具9側のビス挿通孔18bは、ビス24が遊挿できる内径に設定されている。即ち、ビス挿通孔18bは、直径3mmのビス24には内径略4〜5mm、直径4mmのビス24には内径略5〜6mm、直径5mmのビス24には内径略6〜7mmに設定されている。
In addition, three recessed parts 22, 22, and 22 are formed in the outer periphery of the drain hole 3c in the back surface position of the bowl part 3a aligned with the three projecting parts 18c, 18c, and 18c.
A plurality of pilot holes 23, 23, 23 are formed in advance on the outer periphery of the drain hole 3 c of the bowl portion 3 a at a position aligned with each screw insertion hole 18 b of the drainage device 9. Since the pilot holes 23, 23, 23 formed on the back side of the bowl portion 3a are formed when the bowl portion 3a is molded, each pilot hole 23 is formed in an inclined shape in the same direction for molding.
The pilot hole 23 is set to a diameter that allows the screw 24 having a diameter of 3 mm, 4 mm, or 5 mm to be tightened while cutting a screw. Further, the screw insertion hole 18b on the drainage device 9 side is set to an inner diameter into which the screw 24 can be loosely inserted. That is, the screw insertion hole 18b has an inner diameter of about 4 to 5 mm for a screw 24 with a diameter of 3 mm, an inner diameter of about 5 to 6 mm for a screw 24 with a diameter of 4 mm, and an inner diameter of about 6 to 7 mm for a screw 24 with a diameter of 5 mm. Yes.

排水器具9をボウル部3aの裏側に取り付ける際には、OリングOをOリング溝18a内に嵌め込んだ状態で止水鍔部18をボウル部3aの裏面に当接させ、排水孔3cの裏側に本体筒部16を整合させ、各下穴23にビス挿通孔18bを整合させて、各ビス挿通孔18bの下方からそれぞれビス24を下穴23に締め付けてゆく。即ち、ビス24で下穴23にネジを切りながら締め付けてゆき、止水鍔部18をボウル部3aの裏側に水密状に固定することができる。   When the drainage device 9 is attached to the back side of the bowl portion 3a, the waterstop 18 is brought into contact with the back surface of the bowl portion 3a while the O-ring O is fitted in the O-ring groove 18a. The main body cylinder portion 16 is aligned with the back side, the screw insertion holes 18b are aligned with the respective lower holes 23, and the screws 24 are tightened into the lower holes 23 from below the respective screw insertion holes 18b. That is, the screw 24 can be tightened while cutting the screw in the pilot hole 23 to fix the waterstop 18 to the back side of the bowl 3a in a watertight manner.

なお、下穴23は傾斜状を成しているため、ビス24を締め付けてゆく時に水平方向の分力が作用して、排水孔3cと本体筒部16の軸芯がずれて、芯ずれが生じやすく、また、下穴23とビス挿通孔18bの位置にずれが生じている場合にも芯ずれが生じやすくなるが、本例では、排水器具9側に突出されている凸部18c,18c,18cがボウル部3aの裏側に形成されている凹部22,22,22にそれぞれ嵌まり込むことで、ビス24の締め付け固定時の芯ずれを防止できるように構成されている。
従って、凸部18cと凹部22の嵌合により芯ずれが防がれて、排水孔3cの真下に同軸状に排水器具9の本体筒部16を固定することができ、上方から本体筒部16内にヘアキャッチャー部7とオーバーフローキャッチャー8を差し込んだ際に、一体化されているポップアップ弁6がきっちりと排水孔3cに嵌まり込むこととなる。
Since the pilot hole 23 has an inclined shape, a horizontal component acts when the screw 24 is tightened, and the axial centers of the drain hole 3c and the main body cylinder portion 16 are displaced, resulting in misalignment. It is easy to occur, and also when the position of the pilot hole 23 and the screw insertion hole 18b is displaced, misalignment is likely to occur, but in this example, the convex portions 18c and 18c protruding to the drainage device 9 side. , 18c are fitted into the recesses 22, 22 and 22 formed on the back side of the bowl portion 3a, respectively, so that misalignment when the screw 24 is fastened and fixed can be prevented.
Accordingly, misalignment is prevented by fitting the convex portion 18c and the concave portion 22, and the main body cylindrical portion 16 of the drainage device 9 can be fixed coaxially directly below the drainage hole 3c. When the hair catcher portion 7 and the overflow catcher 8 are inserted therein, the integrated pop-up valve 6 is fitted into the drain hole 3c exactly.

なお、この時、ヘアキャッチャー部7の外周は、本体筒部16の内周面16aに形成されているリブ16b,16b,16bにほぼ当接状態となり、ヘアキャッチャー部7の本体筒部16内でのガタツキがなくなる。また、オーバーフローキャッチャー8は縮径部17の内周にほぼ接触状に配置されるものである。
なお、ヘアキャッチャー部7をポップアップ弁6とともに排水孔3cの上方へ引き抜く際には、リブ16bがガイドとなり、ヘアキャッチャー部7に引っ掛かりが生ずることがなく、スムーズに上方へ抜き取ることができるものである。
なお、リブ16bの数は2本であるとヘアキャッチャー部7の着脱時に安定しないため2以上必要であるが、7本以上あると各リブ16bの上面にゴミが溜まりやすくなるため、リブ16bの本数は3〜6が適当である。
At this time, the outer periphery of the hair catcher portion 7 is substantially in contact with the ribs 16b, 16b, and 16b formed on the inner peripheral surface 16a of the main body cylinder portion 16, and the inside of the main body cylinder portion 16 of the hair catcher portion 7 is reached. There is no backlash. Further, the overflow catcher 8 is arranged in a substantially contact manner on the inner periphery of the reduced diameter portion 17.
When the hair catcher portion 7 is pulled out together with the pop-up valve 6 above the drain hole 3c, the rib 16b serves as a guide, and the hair catcher portion 7 is not caught and can be pulled out smoothly. is there.
If the number of ribs 16b is two, two or more are necessary because it is not stable when the hair catcher unit 7 is attached or detached. However, if there are seven or more ribs 16b, dust tends to accumulate on the upper surface of each rib 16b. The number is suitably 3-6.

このように排水孔3cに対する本体筒部16の芯ずれを防いで、ボウル部3aの裏側に排水器具9の止水鍔部18を水密状に当接固定させて、ボウル部3aの裏側に排水金具9を接続することができ、継ぎ目部分に汚れが溜まりにくいものとなる。しかも、排水器具9の本体筒部16は排水孔3cよりも大径に形成されているため、この本体筒部16内を良好に清掃することができるものであり、排水器具9の清掃がしやすいものとなる。   In this way, the center tube portion 16 is prevented from being misaligned with respect to the drain hole 3c, and the waterstop portion 18 of the drainage device 9 is fixed in a watertight manner on the back side of the bowl portion 3a, so that the drainage is discharged on the back side of the bowl portion 3a. The metal fitting 9 can be connected, so that dirt does not easily accumulate at the joint portion. Moreover, since the main body cylinder portion 16 of the drainage device 9 is formed to have a larger diameter than the drainage hole 3c, the inside of the main body cylinder portion 16 can be cleaned well, and the drainage device 9 is cleaned. It will be easy.

また、袋ナット13,20を介してレリース保持部材10およびオーバーフローホース21が排水器具9に接続されているため、袋ナット13,20を手で回して着脱することでメンテナンス性が向上するものとなる。   Moreover, since the release holding member 10 and the overflow hose 21 are connected to the drainage device 9 via the cap nuts 13 and 20, the maintainability is improved by turning the cap nuts 13 and 20 by hand. Become.
