Description

本発明は、キッチンや洗面所に取付けられる水栓装置に関する。   The present invention relates to a faucet device attached to a kitchen or a washroom.

従来からの水栓装置は、開閉ハンドルと連動する開閉バルブと、水栓本体から延設される吐水管と、吐水管の先端に吐水口を有する吐水口キャップと、吐水管と吐水口キャップの間に複数の整流網が設けられており、一般的に吐水管は水栓本体から水平に延設され、吐水口の向きは垂直方向（真下）に向けられていた。
尚、整流網は、吐水口から吐水させる湯水を整流させることや止水時に吐水管内に残った湯水が吐水口から断続的に滴下する現象をおこしにくくすることを目的として設けられているものである。
しかし、最近、キッチンや洗面所に設置される水栓装置は意匠性を考慮し、吐水管が水栓本体から斜め上方に延設されたものや垂直上方向に延設され逆Ｊ字状に形成されたものが主流となってきている。
吐水管が上記のような形状をした水栓装置はキッチンや洗面所での使用者の動作（例えば皿洗いや洗顔）のための空間を確保するために吐水管の前出寸法即ち吐水口の位置が使用者から離れた位置に制限されている。そのため、吐水口の向きが垂直方向（真下）から使用者側に傾けた（垂直方向に対して概ね５°〜４５°）ものが主流になってきている。この場合でも吐水口付近には、上記の目的で整流網が備えられている。（たとえば、特許文献１を参照のこと）
特開２００２−２２７２６２号公報 A conventional faucet device is composed of an opening / closing valve interlocked with an opening / closing handle, a water discharge pipe extending from the water faucet body, a water discharge cap having a water discharge opening at the tip of the water discharge pipe, and a water discharge pipe and a water discharge cap. A plurality of rectifying networks are provided between them, and the water discharge pipe is generally extended horizontally from the faucet body, and the direction of the water discharge port is directed vertically (directly below).
Note that the rectifying network is provided for the purpose of rectifying the hot water discharged from the water discharge port and preventing the hot water remaining in the water discharge pipe from dripping intermittently from the water discharge port at the time of water stoppage. is there.
However, recently, faucet devices installed in kitchens and washrooms are designed in consideration of design, and the water discharge pipes are extended obliquely upward from the faucet body or vertically upward to form an inverted J shape. What has been formed has become mainstream.
The faucet device with the shape of the water discharge pipe as described above is the dimension of the water discharge pipe, that is, the position of the water discharge outlet, in order to secure a space for the user's operation (for example, washing dishes and washing the face) in the kitchen or washroom. Is restricted to a position away from the user. Therefore, the direction in which the water outlet is inclined from the vertical direction (directly below) to the user side (approximately 5 ° to 45 ° with respect to the vertical direction) has become mainstream. Even in this case, a rectifying network is provided in the vicinity of the water outlet for the above purpose. (For example, see Patent Document 1)
JP 2002-227262 A

従来のように、吐水口の向きが使用者の手前側に傾くように構成され、吐水口付近に整流網を備えた水栓装置では、吐水時は従来と同様に整流された吐水となるが、開閉ハンドルを閉止すると、図９に示すように湯水が止まる間際、吐水口キャップ１０１の内壁面１０２（垂直方向より傾いた吐水口の吐水面に対して最も低い位置）に残水１０３が溜まる。（図９（ａ））そして、吐水口キャップ１０１の内壁面１０２の表面張力が切れて残水１０３が流れ出て、（図９（ｂ））吐水口キャップ１０１の先端の平面部１０４に残水１０３が集束し、水滴１０５が生成され表面張力によって落下せず吐水口キャップ１０１の先端に残存することになる。（図９（ｃ））この結果、水栓装置としての品位（見映え）が低下するという課題を有していた。
また、図１０に示すように吐水管２０１が水栓本体２０２から斜め上方に延設された水栓装置２００では、水栓本体２０２を清掃の際、吐水管２０１に湯水をかけてそのまま放置しておくと、残水が吐水管２０１の上部を伝って吐水管２０１の下面側に集束し、水滴２１０が残存する現象が生じ、前述と同様の課題を有する。
そこで、本発明においては、吐水口キャップや吐水管に溝または突起を設けることにより吐水口キャップの平面部や吐水管の下面側に水滴が残存することを防止する水栓装置を提供することを目的とする。 As in the prior art, the faucet device is configured so that the direction of the water discharge port is inclined toward the user's front side, and is provided with a rectifying network in the vicinity of the water discharge port. When the open / close handle is closed, as shown in FIG. 9, the remaining water 103 is collected on the inner wall surface 102 of the water discharge cap 101 (the lowest position with respect to the water discharge surface of the water discharge port inclined from the vertical direction). . Then, the surface tension of the inner wall surface 102 of the spout cap 101 is cut off and the residual water 103 flows out (FIG. 9B), and the residual water is applied to the flat portion 104 at the tip of the spout cap 101. 103 converges and a water droplet 105 is generated and does not fall due to surface tension, and remains at the tip of the water discharge cap 101. (FIG. 9 (c)) As a result, there was a problem that the quality (appearance) of the faucet device was lowered.
Further, in the faucet device 200 in which the water discharge pipe 201 extends obliquely upward from the water faucet body 202 as shown in FIG. 10, when cleaning the water faucet body 202, hot water is applied to the water discharge pipe 201 and left as it is. If this is the case, the residual water will travel along the upper part of the water discharge pipe 201 and converge on the lower surface side of the water discharge pipe 201, resulting in a phenomenon in which the water droplets 210 remain.
Therefore, the present invention provides a water faucet device that prevents water droplets from remaining on the flat portion of the water discharge cap or the lower surface side of the water discharge pipe by providing a groove or a protrusion on the water discharge cap or the water discharge pipe. Objective.

これにより、吐水口キャップの先端に集束する残水を流し落とし水滴の発生を確実に防止することができる。また、溝の深さを５ｍｍ以下にしたため、溝内に付着した汚れやゴミなどの除去を容易に行なうことができる。   Thereby, the residual water converged on the tip of the spout cap can be poured and the generation of water droplets can be reliably prevented. In addition, since the depth of the groove is 5 mm or less, it is possible to easily remove dirt, dust, and the like attached in the groove.

請求項４では、前記突起は幅が０．５ｍｍを超え２ｍｍ以下で、高さが１ｍｍを超え５ｍｍ以下に形成され、前記吐水口キャップの吐水口外周から前記突起までの距離が０．５ｍｍを超え２ｍｍ以下としたことを特徴とする請求項１または請求項２記載の水栓装置。   According to a fourth aspect of the present invention, the protrusion has a width of more than 0.5 mm and not more than 2 mm, a height of more than 1 mm and not more than 5 mm, and a distance from the outer periphery of the outlet of the outlet cap to the protrusion of 0.5 mm. The faucet device according to claim 1 or 2, characterized in that it is more than 2 mm.

これにより、吐水口キャップの先端に集束する残水を流し落とし水滴の発生を確実に防止することができる。また、突起の高さを５ｍｍ以下に形成したので、突起によって吐水が乱れるような悪影響を与えることはない。   Thereby, the residual water converged on the tip of the spout cap can be poured and the generation of water droplets can be reliably prevented. In addition, since the height of the protrusion is 5 mm or less, the protrusion does not adversely affect water discharge.

請求項５では、水栓本体から斜め上方に延設された吐水管を有する水栓装置において、吐水管の下面側に吐水管の延設方向に対し垂直方向に溝または突起を設けたことを特徴とする水栓装置。   According to claim 5, in the faucet device having a water discharge pipe extending obliquely upward from the water faucet body, a groove or a protrusion is provided on the lower surface side of the water discharge pipe in a direction perpendicular to the direction in which the water discharge pipe extends.

A faucet body 4 that mixes to a desired temperature by opening and closing the side handle 3, a water discharge pipe 5 that is attached to the water faucet body 4 and guides hot water, and a water discharge cap 6 provided at the tip of the water discharge pipe 5. It is fixed to the counter 50 of the vanity.

吐水管５は断面が略円形状で、側面視すると水栓本体４から垂直上方向に立ち上がった逆Ｊ字状に形成され、吐水管５の吐水側開口部５ａの方向は垂直方向（真下）より使用者側に１５°傾いている。また、吐水側開口部５ａの内周側には連結具としてのブッシュ７を取付けるために雌ネジ５ｂ、本体側開口部５ｃの外周側には水栓本体４と接続するための雄ネジ５ｄがそれぞれ形成されている。
吐水管５は、金属または合成樹脂で成形され、外観意匠性を向上させることや腐食を抑制することや掃除しやすくする目的で鍍金が施されている。
そして、吐水管２の先端にはブッシュ７を介して、パッキン８、整流網９を収容した吐水口キャップ６が取付けられている。 The water discharge pipe 5 has a substantially circular cross section, and when viewed from the side, is formed in an inverted J shape that rises vertically upward from the faucet body 4, and the direction of the water discharge side opening 5a of the water discharge pipe 5 is the vertical direction (directly below). It is more inclined 15 ° to the user side. Further, a female screw 5b is provided on the inner peripheral side of the water discharge side opening 5a to attach a bush 7 as a coupling tool, and a male screw 5d for connection to the faucet body 4 is provided on the outer peripheral side of the main body side opening 5c. Each is formed.
The water discharge pipe 5 is formed of a metal or a synthetic resin, and is plated for the purpose of improving appearance design, suppressing corrosion, and facilitating cleaning.
A water discharge cap 6 containing a packing 8 and a rectifying network 9 is attached to the tip of the water discharge pipe 2 via a bush 7.

ブッシュ７は金属または合成樹脂で成形され、その外観は略円筒形状であり、外周上部には吐水管５と螺合するための雄ネジ７ａが形成され、外周下部には吐水口キャップ６と螺合するための雄ネジ７ｂが形成されている。中央部は通水のための開口孔７ｃが設けられている。   The bush 7 is formed of metal or synthetic resin, and has an outer appearance of a substantially cylindrical shape. A male screw 7a is formed on the outer peripheral upper portion to be screwed with the water discharge pipe 5, and a spout cap 6 and a screw are formed on the lower outer periphery. A male screw 7b for mating is formed. The central portion is provided with an opening hole 7c for water flow.

パッキン８は、ブッシュ７と吐水口キャップ６の隙間からの漏水を防止するために設けたもので周知の平形パッキンである。   The packing 8 is provided in order to prevent water leakage from the gap between the bush 7 and the spout cap 6 and is a well-known flat packing.

整流網９は、前述のように吐水口から吐水させる湯水を整流させることや止水時に吐水管内に残った湯水が吐水口から断続的に滴下する現象をおこしにくくすることを目的として設けられるものである。
整流網９は、金属や合成樹脂等で成形され、網の線径が０．１〜０．２ｍｍ程度、網の目の一辺が０．１〜０．５ｍｍ程度で円板状に形成されている。そして、吐水口キャップ６内に状況に応じ２〜５枚程度用いるようにしている。 The rectifying network 9 is provided for the purpose of rectifying the hot water discharged from the water discharge port as described above, and preventing the hot water remaining in the water discharge pipe from dripping intermittently from the water discharge port at the time of water stoppage. It is.
The rectifying net 9 is formed of a metal, a synthetic resin, or the like, and is formed in a disk shape with a net wire diameter of about 0.1 to 0.2 mm and one side of the net of about 0.1 to 0.5 mm. Yes. And about 2-5 sheets are used in the spout cap 6 depending on the situation.

吐水口キャップ６は円筒形状に形成され、中央部には貫通する開口孔が設けられている。開口孔は、上部から吐水管５を受け入れる第一開口部６ｂ、ブッシュ７と螺合するための雌ネジ部６ｃ、パッキン８を受け入れる第二開口部６ｄ、整流網９を受け入れる第三開口段部６ｅ、その下部に吐水口６ｆが形成されている。
吐水口キャップ６の先端面は平面部６ｇとなっており、この平面部６ｇに残存する水滴を防止するための溝１０が設けられている。この溝１０は、幅寸法ａが１．５ｍｍ、深さ寸法ｔが０．７５ｍｍで吐水口６ｆの外周からの距離ｘを２ｍｍとして円形状に形成されている。（図４参照） The water discharge cap 6 is formed in a cylindrical shape, and an opening hole is formed in the center thereof. The opening hole has a first opening 6b for receiving the water discharge pipe 5 from above, a female screw part 6c for screwing with the bush 7, a second opening 6d for receiving the packing 8, and a third opening step for receiving the rectifying net 9. 6e, the spout 6f is formed in the lower part.
The front end surface of the spout cap 6 is a flat portion 6g, and a groove 10 for preventing water droplets remaining on the flat portion 6g is provided. The groove 10 is formed in a circular shape with a width dimension a of 1.5 mm, a depth dimension t of 0.75 mm, and a distance x from the outer periphery of the water discharge port 6f of 2 mm. (See Figure 4)

そして、吐水管５の雌ネジ５ｂにブッシュ７を螺合し、パッキン８、整流網９を収容した吐水口キャップ６をブッシュ７に螺合して吐水管５の先端に吐水口キャップ６を取付ける。そして、吐水管５は、本体側開口部５ｃの外周に設けた雄ネジ５ｄを水栓本体４の雌ネジ４ａで所定の位置まで螺合して水栓本体４に取付けられる。   Then, the bush 7 is screwed to the female screw 5 b of the water discharge pipe 5, and the water discharge cap 6 containing the packing 8 and the rectifying network 9 is screwed to the bush 7 to attach the water discharge cap 6 to the tip of the water discharge pipe 5. . The water discharge pipe 5 is attached to the faucet body 4 by screwing a male screw 5d provided on the outer periphery of the main body side opening 5c to a predetermined position with the female screw 4a of the faucet body 4.

このように構成された水栓装置１で水側ハンドル２、湯側ハンドル３をそれぞれ回動操作すると、所望の湯水が生成されるとともに吐水口キャップ６から整流された湯水が吐水される。その後、水側ハンドル２、湯側ハンドル３を反対方向にそれぞれ回動操作すると湯水は止水されるようになっている。
このとき、図５に示すように水栓装置４でも前述した従来技術と同様に吐水口キャップ６の内壁面６ｈに残水１２が溜まる。（図５の（ａ））そして、内壁面６ｈの表面張力が切れ流れ出て、（図５の（ｂ））吐水口キャップ６の平面部６ｇ（垂直方向より傾いた吐水口の吐水面に対して最も低い位置）に残水１２が集束しかけるが、少なくとも吐水口キャップ６の平面部６ｇに対応する位置へ溝１０を設けたため表面張力が切れて水滴ができることなく流れ落ちてしまう。（図５の（ｃ））これによって、水栓装置４の品位（見映え）が低下することを防止することができる。 When the water-side handle 2 and the hot water-side handle 3 are respectively rotated by the faucet device 1 configured as described above, desired hot water is generated and hot water rectified from the water outlet cap 6 is discharged. Thereafter, when the water side handle 2 and the hot water side handle 3 are respectively turned in opposite directions, the hot water is stopped.
At this time, as shown in FIG. 5, the water faucet device 4 also collects residual water 12 on the inner wall surface 6h of the spout cap 6 as in the prior art. Then, the surface tension of the inner wall surface 6h is cut off and flows out (FIG. 5 (b)) with respect to the flat surface portion 6g of the water discharge cap 6 (with respect to the water discharge surface of the water discharge port inclined from the vertical direction). However, since the groove 10 is provided at least at a position corresponding to the flat surface portion 6g of the spout cap 6, the surface tension is cut off and water drops do not form. ((C) of FIG. 5) Thereby, it can prevent that the quality (appearance) of the faucet device 4 falls.

次に、溝１０の形状及び設置場所について説明する。また、表１に、溝の幅寸法と水滴の残存結果を示す。吐水口キャップ６の平面部６ｇに設ける溝１０は、断面形状が凹状または半円弧状に形成されており、表１に示すように幅寸法ａが１ｍｍ以下になると表面張力を切るほどの効果は得られず、２ｍｍ以上でも同様で水滴が溝１０に残存する。溝１０の幅寸法ａが１．５ｍｍの場合、残水は溝１０によって、表面張力が切られて溝１０から流れ落ちて水滴は形成されず吐水口キャップ６の平面部６ｇに残存することはない。よって、溝１０の幅寸法ａは、１ｍｍを超え２ｍｍ未満にすることが好ましい。   Next, the shape and installation location of the groove 10 will be described. Table 1 shows the width of the groove and the remaining water droplets. The groove 10 provided in the flat surface portion 6g of the water discharge cap 6 is formed in a concave or semicircular cross section, and as shown in Table 1, the effect of cutting the surface tension when the width dimension a is 1 mm or less is It is not obtained, and water drops remain in the groove 10 even when the thickness is 2 mm or more. When the width dimension a of the groove 10 is 1.5 mm, the residual water is cut off from the groove 10 by the groove 10 and flows down from the groove 10, so that no water droplets are formed and the remaining water does not remain on the flat portion 6 g of the spout cap 6. . Therefore, the width dimension a of the groove 10 is preferably greater than 1 mm and less than 2 mm.

Figure 2005282250
Figure 2005282250

次に、表２に溝１０の深さ寸法ｔと水滴の残存結果を示す。溝１０の深さは深さ寸法ｔを０．２５ｍｍとした場合、表面張力を切るほどの効果は得られず、吐水口キャップ６の平面部６ｇに水滴が残存する。深さ寸法ｔが０．５ｍｍ以上になると残水は溝１０によって、表面張力が切られて溝１０から流れ落ちて吐水口キャップ６の平面部６ｇに水滴は形成されず、残存することはない。よって、溝１０の深さ寸法ｔは０．５ｍｍ以上にすることが好ましい。
しかし、溝１０の深さ寸法ｔが深くなると溝１０に付着した汚れやゴミなどを除去することが困難になるため、５ｍｍ以下にすることが好ましい。 Next, Table 2 shows the depth dimension t of the groove 10 and the remaining water droplets. When the depth dimension t is 0.25 mm, the depth of the groove 10 is not as effective as cutting the surface tension, and water droplets remain on the flat portion 6 g of the spout cap 6. When the depth dimension t becomes 0.5 mm or more, the residual water is cut off from the groove 10 by the groove 10 and flows down from the groove 10, so that water droplets are not formed on the flat surface portion 6 g of the water discharge cap 6 and do not remain. Therefore, the depth dimension t of the groove 10 is preferably 0.5 mm or more.
However, when the depth dimension t of the groove 10 becomes deep, it becomes difficult to remove dirt, dust and the like adhering to the groove 10, so that it is preferably 5 mm or less.

Figure 2005282250
Figure 2005282250

次に、表３に吐水口外周から溝までの距離と水滴の残存結果について示す。上記のような形状に形成された溝１０を吐水口外周から２．５ｍｍ以上離れた位置に設けると、従来技術と同様の現象が発生して吐水口キャップ６の平面部６ｇに水滴が残存する結果となった。一方、吐水口６ｆの外周から溝１０までの距離ｘを２．０ｍｍ以下とすると残水は溝１０によって、表面張力が切られて溝１０から流れ落ちて吐水口キャップ６の平面部６ｇに水滴は形成されず、残存することはない。また、吐水口キャップ６の平面部６ｇに溝１０を形成するに当たり、溝１０の幅寸法や成形性等を考慮すると距離ｘは０．５ｍｍ以上必要となる。よって、吐水口６ｆの外周から溝１０までの距離ｘは０．５ｍｍを超え２ｍｍ以下となるように溝１０を設置することが好ましい。   Next, Table 3 shows the distance from the outer periphery of the water outlet to the groove and the remaining water droplets. If the groove 10 formed in the shape as described above is provided at a position 2.5 mm or more away from the outer periphery of the water outlet, a phenomenon similar to that of the prior art occurs and water droplets remain on the flat surface portion 6 g of the water outlet cap 6. As a result. On the other hand, if the distance x from the outer periphery of the water discharge port 6f to the groove 10 is 2.0 mm or less, the residual water is cut off from the groove 10 due to the surface tension being cut by the groove 10 and water drops are formed on the flat portion 6g of the water discharge cap 6. It is not formed and does not remain. Further, when the groove 10 is formed in the flat surface portion 6g of the water discharge cap 6, the distance x needs to be 0.5 mm or more in consideration of the width dimension of the groove 10, formability, and the like. Therefore, it is preferable to install the groove 10 so that the distance x from the outer periphery of the water discharge port 6f to the groove 10 is more than 0.5 mm and 2 mm or less.

尚、溝１０は、吐水口６ｆの外周から２ｍｍ以下となる位置で円形状に形成したが、これに限定されることなく、例えば吐水口キャップ６を吐水管５に取付けた状態で、吐水口キャップ６の平面部６ｇで下側となる部位で吐水口６ｆの外周から２ｍｍ以下となる位置に半円弧形状や半楕円形状の溝を設けてもよい。（図６（ａ）参照）
このように溝に方向性が生じる場合は、吐水口キャップ６とブッシュ７を螺合するのではなく、吐水口キャップ６またはブッシュ７の何れかに弾性を有する係止片および突起（何れも図示しない）を設けて接続するようにするとよい。
また、溝１０は上記のような円弧形状とは異なり、吐水口キャップ６の平面部６ｇに吐水口６ｆの外周から吐水口キャップ６の外周に向けて放射状に設けてもよい。（図６（ｂ）参照）
さらに、第一実施形態の水栓装置１では、吐水管５の先端に整流網９が収容された吐水口キャップ６を取付け、吐水口キャップ６の平面部６ｇに溝１０を設けたが、吐水口キャップ６や整流網９を必要としない吐水管の平面部に溝を設けても同様の効果が得られる。 In addition, although the groove | channel 10 was formed circularly in the position used as 2 mm or less from the outer periphery of the water discharge port 6f, it is not limited to this, For example, in the state which attached the water discharge port cap 6 to the water discharge pipe 5, A semicircular arc shape or a semi-elliptical groove may be provided at a position that is 2 mm or less from the outer periphery of the water discharge port 6f in a lower portion of the flat portion 6g of the cap 6. (See Fig. 6 (a))
Thus, when directionality arises in a groove | channel, rather than screwing the water outlet cap 6 and the bush 7, the locking piece and protrusion (both shown in figure) which have elasticity in either the water outlet cap 6 or the bush 7 Do not connect).
Further, unlike the arc shape as described above, the groove 10 may be provided radially on the flat surface portion 6 g of the water discharge cap 6 from the outer periphery of the water discharge port 6 f toward the outer periphery of the water discharge cap 6. (See FIG. 6 (b))
Furthermore, in the faucet device 1 of the first embodiment, the spout cap 6 in which the rectifying network 9 is accommodated is attached to the tip of the spout pipe 5, and the groove 10 is provided in the flat portion 6g of the spout cap 6. The same effect can be obtained even if a groove is provided in the flat portion of the water discharge pipe that does not require the water cap 6 or the rectifying network 9.

また、図７に示すように吐水口キャップ６の平面部６ｇに突起１１を設けても同様の効果が得られる。表４に、突起の幅寸法と水滴の残存結果、表５に、突起の高さ寸法と水滴の残存結果、表６に吐水口外周から突起までの距離と水滴の残存結果について示す。この場合、表４〜表６に示すように突起１１の高さ寸法ｈは１ｍｍ以上、幅寸法ｂは２ｍｍ以下、吐水口外周から突起１１までの距離ｙは前述の溝１０と同様、吐水口外周から２ｍｍ以下の位置に設けることが好ましい。尚、突起１１の高さ寸法ｈは、１ｍｍ以上であれば水滴が残存しないが、水栓装置１の意匠性や吐水への影響を考慮すると５ｍｍ以下にすることが好ましい。また、幅寸法ｂは突起１１の強度や成形性を考慮すると０．５ｍｍ以上にすることが好ましい。   In addition, as shown in FIG. 7, the same effect can be obtained even if the protrusion 11 is provided on the flat portion 6 g of the water discharge cap 6. Table 4 shows the width dimension of the protrusion and the remaining result of the water drop, Table 5 shows the height dimension of the protrusion and the remaining result of the water drop, and Table 6 shows the distance from the outer periphery of the water outlet to the protrusion and the remaining result of the water drop. In this case, as shown in Tables 4 to 6, the height h of the protrusion 11 is 1 mm or more, the width dimension b is 2 mm or less, and the distance y from the outer periphery of the water outlet to the protrusion 11 is the same as the groove 10 described above. It is preferably provided at a position of 2 mm or less from the outer periphery. In addition, although the water droplet does not remain if the height dimension h of the protrusion 11 is 1 mm or more, it is preferable to set it to 5 mm or less in consideration of the design properties of the faucet device 1 and the influence on water discharge. The width dimension b is preferably 0.5 mm or more in consideration of the strength and formability of the protrusions 11.

次に、本発明の第二実施形態について説明する。図８に示すように第二実施形態の水栓装置２１は、湯水の温度調節ならびに流量調節を行うバルブ（図示しない）と、それを操作するレバーハンドル２２、バルブ等が内蔵された水栓本体２３、水栓本体２３から斜め上方に延設する吐水管２４、吐水管２４の先端に設けられた吐水口を有する吐水口キャップ２５で構成されたものである。
そして、第二実施形態の水栓装置２１では吐水管２４の下面側２４ｂには吐水管２４の延設方向と垂直方向に溝２６が複数設けられている。 Next, a second embodiment of the present invention will be described. As shown in FIG. 8, the faucet device 21 of the second embodiment includes a valve (not shown) that adjusts the temperature and flow rate of hot water, a lever handle 22 that operates the faucet body, and a faucet body that incorporates the valve. 23, a water discharge pipe 24 extending obliquely upward from the faucet body 23, and a water discharge cap 25 having a water discharge opening provided at the tip of the water discharge pipe 24.
In the faucet device 21 of the second embodiment, a plurality of grooves 26 are provided on the lower surface side 24b of the water discharge pipe 24 in a direction perpendicular to the extending direction of the water discharge pipe 24.

このように水栓装置で水滴が残存しやすい吐水口キャップや吐水管の下面側に溝または突起を設けることによって、水滴が残存することがなくなり水栓装置の品位を損なうことを防止することができる。 When the dirt and detergent attached to the faucet body 23 of the faucet device 21 according to the second embodiment is washed away with hot water, the hot water flows from the upper surface side 24a to the lower surface side 24b of the water discharge pipe 24, and finally The hot water concentrates on the base of the water discharge pipe 24 to form water droplets, but as described above, the provision of the groove 26 causes the hot water to fall and the water drops to remain on the lower surface side 24b of the water discharge pipe 24. There is no.
Thus, by providing a spout cap or a groove or protrusion on the lower surface side of the water discharge pipe where water droplets are likely to remain in the water faucet device, it is possible to prevent water droplets from remaining and prevent the quality of the water faucet device from being impaired. it can.
