Description

本発明は、吐水装置に関わり、特に、供給された湯水を吐出する吐水装置に関する。 The present invention relates to a water discharge device, and more particularly to a water discharge device that discharges supplied hot water.

浴室や、洗面台、キッチン等で使用される吐水装置は、近年、そのデザイン性が商品価値を大きく左右するようになっている。最近では、特に、吐水装置本体が薄型で、スッキリした外観の商品が市場で好まれる傾向がある。一方、吐水装置本体を金属で構成した場合には、吐水装置から湯を長時間吐出させていると、吐水装置本体が過熱し、これに触れた使用者に不快感を与える原因となる。 In recent years, the design of water spouting devices used in bathrooms, wash basins, kitchens, etc. has greatly influenced the commercial value. Recently, in particular, products with a thin water discharge device body and a neat appearance tend to be preferred in the market. On the other hand, when the water discharge device main body is made of metal, if hot water is discharged from the water discharge device for a long time, the water discharge device main body overheats, which causes discomfort to the user who touches the water discharge device main body.

特開２０１３−７２２３７号公報（特許文献１）には、吐水装置が記載されている。この吐水装置においては、金属製の吐水装置本体の内部に通水管としてホースが挿通され、吐水口まで湯水を導いている。特許文献１記載の吐水装置においては、金属製の吐水装置本体の内部にホースを配置して、この中に湯水を流すことにより、湯水から吐水装置本体への熱伝導を抑制し、使用者に不快感を与えないようにしている。 Japanese Unexamined Patent Publication No. 2013-72237 (Patent Document 1) describes a water spouting device. In this water discharge device, a hose is inserted as a water pipe inside the metal water discharge device main body to guide hot water to the water discharge port. In the water discharge device described in Patent Document 1, a hose is arranged inside the metal water discharge device main body, and hot water is allowed to flow through the hose to suppress heat conduction from the hot water to the water discharge device main body and to the user. I try not to give any discomfort.

しかしながら、特許文献１記載の吐水装置においては、吐水装置本体の内部に円形断面のホースを挿通させているため、このような構造を最近市場で求められている薄型の吐水装置に適用すると、挿通可能なホースが極めて細くなってしまい、十分な吐水流量を得ることができないという問題がある。また、吐水装置本体内部の空間を有効に利用すべく、円形以外の特殊な断面形状のホースを使用すると、製品毎に特殊な形状のホースを特別に製作する必要があり、製造コストが極めて高くなるという問題がある。 However, in the water discharge device described in Patent Document 1, since a hose having a circular cross section is inserted inside the water discharge device main body, when such a structure is applied to a thin water discharge device recently required in the market, the hose is inserted. There is a problem that the possible hose becomes extremely thin and a sufficient discharge water flow rate cannot be obtained. In addition, if a hose with a special cross-sectional shape other than a circular shape is used in order to effectively utilize the space inside the main body of the water discharge device, it is necessary to specially manufacture a hose with a special shape for each product, and the manufacturing cost is extremely high. There is a problem of becoming.

従って、本発明は、吐水装置本体が過熱して使用者に不快感を与えるのを防止すると共に、薄型であっても十分な吐水流量を得ることができる吐水装置を提供することを目的としている。 Therefore, an object of the present invention is to provide a water discharge device capable of preventing the main body of the water discharge device from overheating and causing discomfort to the user and obtaining a sufficient water discharge flow rate even if it is thin. ..

上述した課題を解決するために、本発明は、供給された湯水を吐出する吐水装置であって、吐水装置の外観を構成すると共に、薄型扁平な断面形状を有する筒形の吐水装置本体と、この吐水装置本体の内部に並べて挿通され、同一の給水源から供給された同質の湯水を夫々導く複数の通水管と、吐水装置本体に設けられ、複数の通水管によって導かれた湯水を吐出させる単一の吐水部と、を有し、吐水部には、細長い吐水口と、複数の通水管から導かれた湯水を合流させて吐水口に導く接続通水路が設けられ、接続通水路の流路断面積は複数の通水管の合計の流路断面積よりも大きく、接続通水路には、複数の通水管から導かれた湯水を、接続通水路の内部で分散させる分散部が形成され、吐水口は下方に向けて開口しており、分散部は接続通水路の下側壁面から上方に向けて立ち上がる分散壁面を備え、各通水管の流路断面の下流方向への投影面の一部は分散壁面と干渉し、投影面の残部は分散壁面と干渉せず、各通水管から流出した湯水が分散壁面に衝突することなく分散壁面を越えて流れることを特徴としている。 In order to solve the above-mentioned problems, the present invention is a water spouting device that discharges the supplied hot water, and constitutes the appearance of the water spouting device, and has a tubular water spouting device main body having a thin and flat cross-sectional shape. A plurality of water pipes that are inserted side by side inside the main body of the water discharge device and guide the same quality hot water supplied from the same water supply source, and hot water that is provided in the main body of the water discharge device and is guided by the plurality of water pipes are discharged. possess a single water discharge portion, and the water discharger, elongated spout, connected water conduit is provided are merged hot water derived from a plurality of water pipe and leading to spout, the flow of the connection water passage The cross-sectional area of the passage is larger than the total cross-sectional area of the flow path of the plurality of water pipes, and the connecting water pipe is formed with a dispersion portion for dispersing hot water guided from the plurality of water pipes inside the connecting water pipe. The spout is open downward, and the dispersion part is provided with a dispersion wall surface that rises upward from the lower side wall surface of the connecting water pipe, and is a part of the projection surface in the downstream direction of the flow path cross section of each water pipe. Is characterized in that it interferes with the dispersed wall surface, the rest of the projection surface does not interfere with the dispersed wall surface, and the hot water flowing out from each water pipe flows over the dispersed wall surface without colliding with the dispersed wall surface .

このように構成された本発明においては、薄型扁平な断面形状を有する筒形の吐水装置本体の内部に、複数の通水管が並べて挿通されている。これらの通水管には同一の給水源から供給された同質の湯水が夫々流れ、これらの通水管によって導かれた湯水は単一の吐水部から吐出される。 In the present invention configured as described above, a plurality of water pipes are inserted side by side inside a tubular water discharge device main body having a thin and flat cross-sectional shape. Homogeneous hot water supplied from the same water source flows through these water pipes, and the hot water guided by these water pipes is discharged from a single water discharge unit.

このように構成された本発明によれば、吐水装置本体の内部に湯水を導く通水管が挿通されているので、吐水装置本体を金属で形成した場合にも、通水管内の湯水から吐水装置本体への熱伝導が抑制され、吐水装置本体が過熱して、これに触れた使用者に不快感を与えるのを防止することができる。また、このように構成された本発明によれば、吐水装置本体の内部に同一の給水源から供給された同質の湯水が流れる通水管が複数並べて挿通されているので、細い通水管を使用した場合でも吐水部から十分な流量の吐水を得ることができる。また、吐水装置本体の内部に通水管を複数配置することにより、円形断面の通水管を使用した場合でも、薄型扁平な断面形状を有する吐水装置本体の内部に、十分な流路断面積を確保することができ、十分な吐水流量を得ることができる。 According to the present invention configured in this way, since the water pipe for guiding the hot water is inserted inside the water discharge device main body, even when the water discharge device main body is made of metal, the water discharge device is made from the hot water in the water discharge pipe. The heat conduction to the main body is suppressed, and it is possible to prevent the main body of the water discharge device from overheating and causing discomfort to the user who touches the main body. Further, according to the present invention configured as described above, since a plurality of water pipes through which hot water of the same quality supplied from the same water supply source flows are inserted side by side inside the main body of the water discharge device, a thin water pipe is used. Even in this case, a sufficient flow rate of water can be obtained from the water discharge unit. Further, by arranging a plurality of water pipes inside the water discharge device main body, a sufficient flow path cross-sectional area is secured inside the water discharge device main body having a thin and flat cross-sectional shape even when a water pipe having a circular cross section is used. It is possible to obtain a sufficient discharge water flow rate.

吐水口が細長く形成されている場合、吐水口に導かれる湯水の流速分布が不均一であると、吐水口から均一に吐水が行われず、吐出された湯水の流れが醜く変形してしまう。上記のように構成された本発明によれば、複数の通水管から導かれた湯水を合流させて吐水口に導く接続通水路に、湯水を分散させる分散部が形成されているので、細長い吐水口に導かれる湯水の流速を均等に近付けることができ、吐水口から美観に優れた滝状（膜状）の吐水を得ることができる。 When the spout is elongated and the flow velocity distribution of the hot water guided to the spout is not uniform, the spout does not uniformly spout water, and the flow of the discharged hot water is ugly and deformed. According to the present invention configured as described above, since a dispersion portion for dispersing hot water is formed in a connecting water passage that merges hot water guided from a plurality of water pipes and leads to a spout, an elongated discharge is performed. The flow velocity of the hot water guided to the water outlet can be made evenly close to each other, and a waterfall-like (membrane-like) water discharge having an excellent appearance can be obtained from the water outlet.

このように構成された本発明によれば、分散部が接続通水路の下側壁面から上方に向けて立ち上がる分散壁面を備えているので、複数の通水管から流出した湯水は分散壁面に衝突して上方に向けられた後、下方に向けて開口した吐水口から吐出される。これにより、狭いスペースで流れを分散させ、流速を均等に近付けることができるので、美観に優れた滝状（膜状）の吐水を得るための分散部をコンパクトに構成することができる。
また、このように構成された本発明によれば、各通水管の投影面の一部が干渉するように分散壁面が形成されているので、各通水管から吐出された湯水の一部は分散壁面に衝突する一方、残りの部分は分散壁面に直接衝突せず分散壁面を越えて流れる。通水管から流出した湯水を分散壁面に衝突させることにより湯水の流れを分散させることができるが、流出した湯水の全てを分散壁面に衝突させると、分散壁面による流路抵抗が大きくなりすぎ、吐水口から吐出される湯水の流速が大幅に低下してしまう。吐水口から吐出される湯水の流速が低下すると、細長い吐水口から吐出された幅広の流れが、縮流により急速に流れの幅が狭くなってしまい、美観に優れた滝状（膜状）の吐水が得られなくなる。上記のように構成された本発明によれば、各通水管から吐出された湯水の一部を分散壁面に衝突させているので、湯水の分散性と流速を適切にバランスさせることができ、美観に優れた滝状（膜状）の吐水を得ることができる。 According to the present invention constructed as this, since the dispersing section is provided with a dispersion wall rising upward from the bottom wall surface of the connecting water passage, the hot water flowing out from a plurality of water pipe collides with dispersion wall After being directed upward, it is discharged from a spout that opens downward. As a result, the flow can be dispersed in a narrow space and the flow velocity can be evenly approached, so that the dispersion portion for obtaining a waterfall-like (membrane-like) water discharge having an excellent aesthetic appearance can be compactly configured.
Further, according to the present invention configured in this way, since the dispersed wall surface is formed so that a part of the projection surface of each water pipe interferes with each other, a part of the hot water discharged from each water pipe is dispersed. While colliding with the wall surface, the rest does not directly collide with the dispersed wall surface and flows over the dispersed wall surface. The flow of hot water can be dispersed by colliding the hot water flowing out of the water pipe with the dispersed wall surface, but if all the flowing hot water collides with the dispersed wall surface, the flow path resistance due to the dispersed wall surface becomes too large and discharges. The flow velocity of the hot water discharged from the water outlet is significantly reduced. When the flow velocity of the hot water discharged from the spout decreases, the wide flow discharged from the elongated spout rapidly narrows due to the contraction, resulting in an aesthetically pleasing waterfall (membrane) shape. Water spouting cannot be obtained. According to the present invention configured as described above, since a part of the hot water discharged from each water pipe is made to collide with the dispersed wall surface, the dispersibility and the flow velocity of the hot water can be appropriately balanced, which is aesthetically pleasing. It is possible to obtain excellent waterfall-like (membrane-like) water discharge.

本発明において、好ましくは、分散部は、さらに、吐水口の上方に形成された下向き壁面を備え、分散壁面は下流側に向けて流路が狭くなるように傾斜して形成され、分散壁面により上方に向けられた湯水の流れが下向き壁面に衝突して吐水口から吐出される。 In the present invention, preferably, the dispersion portion further includes a downward wall surface formed above the spout, and the dispersion wall surface is formed so as to be inclined so that the flow path becomes narrower toward the downstream side. The flow of hot water directed upward collides with the downward wall surface and is discharged from the spout.

このように構成された本発明によれば、分散壁面が傾斜して形成され、分散壁面により上方に向けられた湯水の流れが下向き壁面に衝突して吐出されるので、各通水管から流出した湯水は、まず分散壁面に衝突して分散された後、さらに下向き壁面に衝突して分散される。このため、各通水管から流出した湯水は、二段階に分散され、吐水口から吐出される湯水の流速をさらに均等に近付けることができる。 According to the present invention configured in this way, the dispersed wall surface is formed to be inclined, and the flow of hot water directed upward by the dispersed wall surface collides with the downward wall surface and is discharged, so that the dispersed wall surface flows out from each water passage pipe. The hot water first collides with the dispersed wall surface and is dispersed, and then further collides with the downward wall surface and is dispersed. Therefore, the hot water flowing out from each water pipe is dispersed in two stages, and the flow velocity of the hot water discharged from the spout can be made closer evenly.

また、本発明は、供給された湯水を吐出する吐水装置であって、吐水装置の外観を構成すると共に、薄型扁平な断面形状を有する筒形の吐水装置本体と、この吐水装置本体の内部に並べて挿通され、同一の給水源から供給された同質の湯水を夫々導く複数の通水管と、吐水装置本体に設けられ、複数の通水管によって導かれた湯水を吐出させる単一の吐水部と、を有し、吐水部には、細長い吐水口と、複数の通水管から導かれた湯水を合流させて吐水口に導く接続通水路が設けられ、接続通水路の流路断面積は複数の通水管の合計の流路断面積よりも大きく、接続通水路には、複数の通水管から導かれた湯水を、接続通水路の内部で分散させる分散部が形成され、吐水口は下方に向けて開口しており、分散部は接続通水路の下側壁面から上方に向けて立ち上がる分散壁面を備え、分散壁面は、各通水管の流路断面の下流方向への投影面と干渉する部分が、干渉しない部分よりも高く構成されていることを特徴としている。
このように構成された本発明によれば、分散壁面が、各通水管の投影面と干渉する部分では高く、干渉しない部分では低く構成されているので、分散壁面の高い部分に衝突した湯水は左右に広がって分散壁面をその低い部分から乗り越えるので、分散壁面に衝突した湯水の左右への分散が助長され、吐水口から吐出される湯水の流速を、より均一に近付けることができる。 Further, the present invention is a water spouting device that discharges the supplied hot water, and constitutes the appearance of the water spouting device, and has a tubular water spouting device main body having a thin and flat cross-sectional shape and the inside of the water spouting device main body. Multiple water pipes that are inserted side by side and guide the same quality of hot water supplied from the same water supply source, and a single water discharge unit that is provided in the main body of the water discharge device and discharges hot water guided by multiple water pipes. The spouting part is provided with an elongated spout and a connecting water passage that merges hot water guided from a plurality of water pipes and leads to the spout, and the cross-sectional area of the flow path of the connecting water pipe is a plurality of passages. It is larger than the total cross-sectional area of the flow path of the water pipes, and the connecting water pipes are formed with a dispersion part that disperses hot water guided from multiple water pipes inside the connecting water pipes, and the spout is directed downward. It is open, and the dispersion part is provided with a dispersion wall surface that rises upward from the lower side wall surface of the connecting water pipe, and the distribution wall surface has a portion that interferes with the projection surface in the downstream direction of the flow path cross section of each water pipe. It is characterized by being configured higher than the non-interfering part.
According to the present invention configured in this way, the dispersed wall surface is configured to be high in the portion that interferes with the projection surface of each water pipe and low in the portion that does not interfere with each other. Since it spreads to the left and right and overcomes the dispersed wall surface from the lower portion, the dispersion of the hot water that collides with the dispersed wall surface to the left and right is promoted, and the flow velocity of the hot water discharged from the spout can be made closer to more uniform.

本発明の吐水装置によれば、薄型でありながら、吐水装置本体が過熱して使用者に不快感を与えるのを防止すると共に、十分な吐水流量を得ることができる。 According to the water discharge device of the present invention, it is possible to prevent the main body of the water discharge device from overheating and causing discomfort to the user, and to obtain a sufficient water discharge flow rate, while being thin.

次に、添付図面を参照して、本発明の好ましい実施形態を説明する。
図１は、本発明の実施形態による吐水装置を備えた洗面台の斜視図である。
図１に示すように、本発明の実施形態の吐水装置１は、カウンターボード４上に配置された洗面ボウル２に隣接して設置され、洗面ボウル２に向けて湯水（水又は湯）を吐出するように構成されている。 Next, a preferred embodiment of the present invention will be described with reference to the accompanying drawings.
FIG. 1 is a perspective view of a wash basin provided with a water discharge device according to an embodiment of the present invention.
As shown in FIG. 1, the water discharge device 1 of the embodiment of the present invention is installed adjacent to the wash bowl 2 arranged on the counter board 4, and discharges hot water (water or hot water) toward the wash bowl 2. It is configured to do.

本実施形態の吐水装置１は、カウンターボード４からほぼ垂直に立ち上がる垂直部１ａと、この垂直部１ａの上端からほぼ水平に延びる水平部１ｂから構成された概ね逆Ｌ字型の吐水装置であり、水平部１ｂの下面先端部に設けられた吐水口１ｃから吐水が為されるようになっている。また、吐水装置１は、極めて薄型で扁平な断面形状を有しており、スリムでスッキリとした外観を得ている。この吐水装置１により吐水を行う際には、使用者は、洗面ボウル２横に配置された操作部６を操作する。これにより、上水道に接続された水用電磁弁（図示せず）、及び給湯器に接続された湯用電磁弁（図示せず）が開弁され、これらを通過した水及び湯がサーモ水栓（図示せず）により適温に混合される。温度調整された湯水は吐水装置１の内部を通って先端の吐水口１ｃから洗面ボウル２に向けて吐出される。 The water discharge device 1 of the present embodiment is a substantially inverted L-shaped water discharge device composed of a vertical portion 1a rising substantially vertically from the counter board 4 and a horizontal portion 1b extending substantially horizontally from the upper end of the vertical portion 1a. Water is discharged from the water discharge port 1c provided at the tip of the lower surface of the horizontal portion 1b. Further, the water discharge device 1 has an extremely thin and flat cross-sectional shape, and has a slim and neat appearance.

As a result, the solenoid valve for water (not shown) connected to the water supply and the solenoid valve for hot water (not shown) connected to the water heater are opened, and the water and hot water that have passed through these are thermo-faucets. (Not shown) is mixed at an appropriate temperature. The temperature-controlled hot water passes through the inside of the water discharge device 1 and is discharged from the water discharge port 1c at the tip toward the wash bowl 2.

次に、図２及び図３を参照して、本発明の実施形態による吐水装置１の内部構造を説明する。
図２は吐水装置１の側面断面図であり、図３は吐水装置１の分解斜視図である。
図２及び図３に示すように、本実施形態による吐水装置１は、吐水装置本体８と、この吐水本体の内部に収容された２本の通水管１０と、これらの通水管１０に接続され、吐水部を形成する吐水部形成部材１２と、吐水装置本体８内に配置された上部補強板１４及び下部補強板１６と、吐水装置本体８の下端に取り付けられたベース部材１８と、を有する。 Next, the internal structure of the water discharge device 1 according to the embodiment of the present invention will be described with reference to FIGS. 2 and 3.
FIG. 2 is a side sectional view of the water discharge device 1, and FIG. 3 is an exploded perspective view of the water discharge device 1.
As shown in FIGS. 2 and 3, the water discharge device 1 according to the present embodiment is connected to a water discharge device main body 8, two water pipes 10 housed inside the water discharge main body, and these water pipes 10. It has a water discharge portion forming member 12 for forming a water discharge portion, an upper reinforcing plate 14 and a lower reinforcing plate 16 arranged in the water discharge device main body 8, and a base member 18 attached to the lower end of the water discharge device main body 8. ..

吐水装置本体８は、プレス加工を施したステンレス製の板材から形成されており、全体として、逆Ｌ字型に屈曲された筒形に形成されている。また、吐水装置本体８は、その基端部においても前方に向けて屈曲されており、水平部よりも短いベース部が形成されている。さらに、吐水装置本体８の水平部における横断面は、上面側が直線であり、下面側が下方に向けて凸の弓形に形成され、ほぼ同一の断面形状が垂直部１ａまで連続して、基端部を除くほぼ全体が同一の断面形状を有している。また、本実施形態において、吐水装置本体８の横断面は、幅５５ｍｍ、高さ８．６ｍｍの扁平薄型に構成されており、横断面が中央から両側の端部に向けて薄くなるように構成されているため、使用者には、さらに薄型の印象を与える。本実施形態の吐水装置１においては、吐水装置本体８を板材から構成することにより、このような極限的な薄さが実現されている。 The water discharge device main body 8 is formed of a pressed stainless steel plate material, and is formed as a whole in an inverted L-shaped bent tubular shape. Further, the water discharge device main body 8 is also bent forward at its base end portion, and a base portion shorter than the horizontal portion is formed. Further, the cross section of the horizontal portion of the water discharge device main body 8 is formed in a straight line on the upper surface side and a convex bow shape on the lower surface side toward the lower side, and substantially the same cross-sectional shape is continuous up to the vertical portion 1a, and the base end portion. Almost all of them have the same cross-sectional shape except for. Further, in the present embodiment, the cross section of the water discharge device main body 8 is configured to be flat and thin with a width of 55 mm and a height of 8.6 mm, and the cross section is configured to become thinner from the center toward both end portions. Because it is made, it gives the user the impression of being thinner. In the water discharge device 1 of the present embodiment, such an extremely thinness is realized by forming the water discharge device main body 8 from a plate material.

図３に示すように、吐水装置本体８は、５つの外観部品を組み合わせることにより形成されている。即ち、吐水装置本体８は、第１外観部品８ａ、第２外観部品８ｂ、第３外観部品８ｃ、及び第４外観部品８ｄから構成されている。これらの外観部品のうち、第２外観部品８ｂ、第３外観部品８ｃ、及び第４外観部品８ｄは溶接により互いに接合され前側外観部品９が形成される。この前側外観部品９を第１外観部品８ａと結合されることにより、筒状の吐水装置本体８が形成される。 As shown in FIG. 3, the water discharge device main body 8 is formed by combining five appearance parts. That is, the water discharge device main body 8 is composed of a first appearance component 8a, a second appearance part 8b, a third appearance part 8c, and a fourth appearance part 8d. Of these appearance parts, the second appearance part 8b, the third appearance part 8c, and the fourth appearance part 8d are joined to each other by welding to form the front appearance part 9. By combining the front appearance component 9 with the first appearance component 8a, a tubular water discharge device main body 8 is formed.

第１外観部品８ａは、ステンレス製の細長い平板を、所定の半径でＬ字型に湾曲させることにより形成されている。Ｌ字型の第１外観部品８ａの内側の垂直及び水平の直線部分には結合用金具２０が取り付けられている（図１には、垂直部分の結合用金具のみ図示）。 The first appearance component 8a is formed by bending an elongated flat plate made of stainless steel into an L shape with a predetermined radius. The connecting metal fittings 20 are attached to the vertical and horizontal straight portions inside the L-shaped first external component 8a (in FIG. 1, only the connecting metal fittings in the vertical portion are shown).

第２外観部品８ｂは、ステンレス製の細長い平板を、所定の半径でＬ字型に湾曲させると共に、幅方向中央が弓形に突出するように、幅方向にも湾曲させることにより形成されている。第２外観部品８ｂは、第１外観部品８ａと合致する形態に形成され、第１外観部品８ａと結合することにより、扁平薄型の断面形状を有する筒形の部材が形成される。また、Ｌ字型の第２外観部品８ｂの外側の垂直及び水平の直線部分には結合用金具２２が取り付けられている（図１には、水平部分の結合用金具のみ図示）。これらの結合用金具２２が、第１外観部品８ａの結合用金具２０とスナップ嵌めされることにより、第１外観部品８ａと第２外観部品８ｂが結合される。 The second exterior component 8b is formed by bending an elongated flat plate made of stainless steel into an L shape with a predetermined radius and also bending it in the width direction so that the center in the width direction protrudes in an arch shape. The second appearance part 8b is formed in a form that matches the first appearance part 8a, and by combining with the first appearance part 8a, a tubular member having a flat and thin cross-sectional shape is formed. Further, the connecting metal fittings 22 are attached to the vertical and horizontal straight lines on the outside of the L-shaped second external component 8b (in FIG. 1, only the connecting metal fittings in the horizontal portion are shown). By snap-fitting these connecting metal fittings 22 with the connecting metal fittings 20 of the first external component 8a, the first external component 8a and the second external component 8b are joined.

第３外観部品８ｃは全体として小さいＬ字型の部材であり、ステンレス製の平板を、プレス加工によりにＬ字型に湾曲させると共に、幅方向中央が弓形に突出するように、幅方向にも湾曲させることにより形成されている。第３外観部品８ｃの上端の端面は、第２外観部品８ｂの下端の端面と突き合わせた状態で溶接され、第２外観部品８ｂと一体化されている。このように、第２外観部品８ｂと第３外観部品８ｃの接合部は、吐水装置本体８の屈曲した部分の近傍に設けられている。また、第３外観部品８ｃの背面は第１外観部品８ａの下端部と合致するように形成され、第３外観部品８ｃの底面はベース部材１８と結合され、吐水装置本体８の基端部の屈曲した部分を構成する。 The third exterior component 8c is a small L-shaped member as a whole, and the stainless steel flat plate is curved into an L-shape by press working, and also in the width direction so that the center in the width direction protrudes in an arch shape. It is formed by bending. The upper end face of the third appearance component 8c is welded in a state of being abutted against the lower end face of the second appearance part 8b, and is integrated with the second appearance part 8b. As described above, the joint portion between the second appearance component 8b and the third appearance component 8c is provided in the vicinity of the bent portion of the water discharge device main body 8.

FIG. 4 is an enlarged side sectional view showing an enlarged tip portion of the water discharge device 1 according to the embodiment of the present invention. FIG. 5 is an enlarged plan sectional view showing an enlarged tip portion of the water discharge device 1 according to the embodiment of the present invention. FIG. 6 is a cross-sectional view of the tip end portion of the water discharge device 1 according to the embodiment of the present invention cut along the line VI-VI of FIG.

まず、図４に示すように、吐水装置１の先端部には吐水部形成部材１２が内蔵されており、この吐水部形成部材１２の下面には吐水口形成部材３０が取り付けられ、この吐水口形成部材３０は、第４外観部品８ｄに形成された開口２４を介して外部に露出している。また、図２に示すように、吐水部形成部材１２は上面が平面であり、下面が弓形に膨らんだ板状の形態に形成されている。吐水部形成部材１２の内部には、各通水管１０から導かれた湯水を合流させ、吐水口１ｃに導く接続通水路が形成されている。 First, as shown in FIG. 4, a water discharge portion forming member 12 is built in the tip portion of the water discharge device 1, and a water discharge port forming member 30 is attached to the lower surface of the water discharge portion forming member 12, and the water discharge port is formed. The forming member 30 is exposed to the outside through the opening 24 formed in the fourth appearance component 8d. Further, as shown in FIG. 2, the water discharge portion forming member 12 has a flat upper surface and is formed in a plate-like shape in which the lower surface bulges in an arch shape. Inside the water discharge portion forming member 12, a connecting water passage is formed in which hot water guided from each water pipe 10 is merged and led to the water discharge port 1c.

一方、図４及び図５に示すように、吐水部形成部材１２の後端面から前方に向けて延びるように、２本の通水管１０を夫々接続するための２本の流入流路１２ａが平行に形成されている。本実施形態においては、各通水管１０の内径と、各流入流路１２ａの湯水が流れる部分の内径はほぼ同一であり、ほぼ同一の流路断面積を有している。また、吐水部形成部材１２の下面には、吐水口形成部材３０を受け入れるための長円形断面の凹部１２ｂが形成されている。凹部１２ｂの奥部には切欠部１２ｃが形成されており、各流入流路１２ａの先端は、切欠部１２ｃを介して凹部１２ｂの内部に連通している。また、各流入流路１２ａの相互間も切欠部１２ｃを介して連通されている。 On the other hand, as shown in FIGS. 4 and 5, two inflow channels 12a for connecting the two water pipes 10 are parallel to each other so as to extend forward from the rear end surface of the water discharge portion forming member 12. Is formed in. In the present embodiment, the inner diameter of each water pipe 10 and the inner diameter of the portion of each inflow flow path 12a through which hot water flows are substantially the same, and have substantially the same flow path cross-sectional area. Further, a recess 12b having an oval cross section for receiving the spout forming member 30 is formed on the lower surface of the water spout forming member 12. A notch 12c is formed in the inner portion of the recess 12b, and the tip of each inflow flow path 12a communicates with the inside of the recess 12b via the notch 12c. Further, the inflow flow paths 12a are also communicated with each other via the notch 12c.

吐水口形成部材３０は、吐水部形成部材１２に形成された凹部１２ｂに嵌め込まれるように形成された樹脂製の部材である。図３に示すように、吐水口形成部材３０は、吐水部形成部材１２の下面に合致する形状に湾曲された板状部３０ａと、この板状部３０ａを貫通するように形成された長円形断面の筒状部３０ｂと、を有する。板状部３０ａの上面は、吐水部形成部材１２の下面と当接するように配置され、板状部３０ａの下面が第４外観部品８ｄの開口２４を介して外部に露出する。筒状部３０ｂの下端の開口は、横方向に細長い、幅広の吐水口１ｃを形成している。なお、本実施形態においては、吐水口１ｃは、長さ４０ｍｍ、幅４ｍｍの長円形に構成されている。筒状部３０ｂは、吐水部形成部材１２の凹部１２ｂとほぼ同一の形状に構成され、筒状部３０ｂの上側の部分が凹部１２ｂの中に嵌め込まれる。筒状部３０ｂの外周面と凹部１２ｂの内壁面との間にはパッキン３２が配置され、それらの間の水密性が確保されている。また、筒状部３０ｂの内部には、長円形に形成された４枚の整流網２８が配置されている。 The spout forming member 30 is a resin member formed so as to be fitted into the recess 12b formed in the spout forming member 12. As shown in FIG. 3, the spout forming member 30 has a plate-shaped portion 30a curved in a shape matching the lower surface of the water spout forming member 12 and an oval formed so as to penetrate the plate-shaped portion 30a. It has a tubular portion 30b in cross section. The upper surface of the plate-shaped portion 30a is arranged so as to be in contact with the lower surface of the water discharge portion forming member 12, and the lower surface of the plate-shaped portion 30a is exposed to the outside through the opening 24 of the fourth appearance component 8d. The opening at the lower end of the tubular portion 30b forms a wide spout 1c elongated in the lateral direction. In the present embodiment, the spout 1c is formed in an oval shape having a length of 40 mm and a width of 4 mm. The tubular portion 30b is configured to have substantially the same shape as the recess 12b of the water discharge portion forming member 12, and the upper portion of the tubular portion 30b is fitted into the recess 12b. A packing 32 is arranged between the outer peripheral surface of the tubular portion 30b and the inner wall surface of the recess 12b, and watertightness between them is ensured. Further, inside the tubular portion 30b, four rectifying nets 28 formed in an oval shape are arranged.

図６に示すように、吐水口形成部材３０の筒状部３０ｂ上端の、各流入流路１２ａと対向する側には、切欠部３０ｃが形成されている。この切欠部３０ｃは、長円形の筒状部３０ｂの上縁の直線部分を切り欠くように形成され、各流入流路１２ａから流入した湯水は、切欠部３０ｃと、凹部１２ｂの最奥部の下向き壁面１２ｅとの間の隙間を通って筒状部３０ｂの内側に流入する。また、図４に示すように、切欠部３０ｃの表面は、筒状部３０ｂの外側から内側に向けて高くなる傾斜面として形成されており、この傾斜により、各流入流路１２ａから流入した湯水の流路は下流側に向けて狭くされている。 As shown in FIG. 6, a notch 30c is formed on the upper end of the tubular portion 30b of the spout forming member 30 on the side facing each inflow flow path 12a. The notch 30c is formed so as to cut out a straight portion of the upper edge of the oval tubular portion 30b, and the hot water flowing from each inflow flow path 12a is formed in the notch 30c and the innermost portion of the recess 12b. It flows into the inside of the tubular portion 30b through a gap between the downward wall surface 12e and the tubular portion 30b. Further, as shown in FIG. 4, the surface of the notch portion 30c is formed as an inclined surface that rises from the outside to the inside of the tubular portion 30b, and due to this inclination, hot water that has flowed in from each inflow flow path 12a. The flow path of is narrowed toward the downstream side.

このような吐水部形成部材１２の内部構成により、各通水管１０から供給された湯水は、まず吐水部形成部材１２の各流入流路１２ａに夫々流入する。各流入流路１２ａに流入した湯水は、流入流路１２ａの下流端の立上り壁面１２ｄ（図４）に衝突し、吐水部形成部材１２に設けられた切欠部１２ｃ（図５）の中に流入して合流する。即ち、各通水管１０から供給された湯水は、吐水部形成部材１２内で下側の壁面から上方に立ち上がった立上り壁面１２ｄに衝突して分散され、切欠部１２ｃの中に流入する。 Due to the internal configuration of the water discharge portion forming member 12, the hot water supplied from each water pipe 10 first flows into each inflow flow path 12a of the water discharge portion forming member 12. The hot water that has flowed into each inflow flow path 12a collides with the rising wall surface 12d (FIG. 4) at the downstream end of the inflow flow path 12a and flows into the notch portion 12c (FIG. 5) provided in the water discharge portion forming member 12. And join. That is, the hot water supplied from each water pipe 10 collides with the rising wall surface 12d rising upward from the lower wall surface in the water discharge portion forming member 12, is dispersed, and flows into the notch portion 12c.

切欠部１２ｃに流入した湯水の流れは、吐水口形成部材３０の筒状部３０ｂに形成された切欠部３０ｃの傾斜した壁面によって上方に向けられ、吐水部形成部材１２の下向き壁面１２ｅに衝突してさらに分散される。下向き壁面１２ｅに衝突した湯水の流れは、さらに筒状部３０ｂの内壁面に衝突してさらに分散される。これにより、２本の通水管１０から供給された湯水の流れは、吐水部形成部材１２の内部で種々の壁面に衝突して分散され、筒状部３０ｂの内側では、ほぼ均一な流速を有するようになる。 The flow of hot water flowing into the notch portion 12c is directed upward by the inclined wall surface of the notch portion 30c formed in the tubular portion 30b of the spout forming member 30, and collides with the downward wall surface 12e of the water spout forming member 12. Is further dispersed. The flow of hot water that collides with the downward wall surface 12e further collides with the inner wall surface of the tubular portion 30b and is further dispersed. As a result, the flow of hot water supplied from the two water pipes 10 collides with various wall surfaces inside the water discharge portion forming member 12 and is dispersed, and has a substantially uniform flow velocity inside the tubular portion 30b. Will be.

このように、吐水部形成部材１２の内部に設けられた各壁面は、２本の通水管１０から導かれた湯水を接続通水路の内部で分散させる「分散部」として機能している。筒状部３０ｂの内側に流入した湯水は、筒状部３０ｂ内に配置された４枚の整流網２８によって整流され、ほぼ均一な流速で吐水口１ｃから下方に向けて吐出される。このように、流入流路１２ａの下流端に設けられた、接続通水路の下側壁面から上方に向けて立ち上がる立上り壁面１２ｄ（図４）、及び吐水口形成部材３０の筒状部３０ｂ上端に形成された切欠部３０ｃの傾斜した壁面（図４）は、２本の通水管１０から導かれた湯水の流れを分散させる「分散壁面」として機能する。 In this way, each wall surface provided inside the water discharge portion forming member 12 functions as a "dispersion portion" that disperses the hot water guided from the two water pipes 10 inside the connecting water passage. The hot water that has flowed into the tubular portion 30b is rectified by the four rectifying nets 28 arranged in the tubular portion 30b, and is discharged downward from the spout 1c at a substantially uniform flow velocity. In this way, on the rising wall surface 12d (FIG. 4) provided at the downstream end of the inflow flow path 12a and rising upward from the lower side wall surface of the connecting water passage, and on the upper end of the tubular portion 30b of the spout forming member 30. The inclined wall surface (FIG. 4) of the formed notch 30c functions as a “dispersed wall surface” that disperses the flow of hot water guided from the two water pipes 10.

また、図６に示すように、筒状部３０ｂ上端の切欠部３０ｃと下向き壁面１２ｅの間の隙間からは、各流入流路１２ａの下流端の開口が見えている。即ち、流入流路１２ａ（通水管１０の流路断面）の下流方向への投影面は、その一部が立上り壁面１２ｄ（図４）や吐水口形成部材３０の筒状部３０ｂと干渉しているが、残りの部分はこれらと干渉せず、切欠部３０ｃと下向き壁面１２ｅの間の隙間に位置する。このため、各通水管１０から各流入流路１２ａを介して吐水部形成部材１２内に流入した湯水は、その一部が立上り壁面１２ｄや筒状部３０ｂの外周面等の「分散壁面」に衝突するが、残りの部分はこれらに直接衝突することなく筒状部３０ｂの内側に直接流入する。このため各通水管１０から導かれた湯水は、流速が過度に低下されることなく分散され、適度な流速を維持すると共に、ほぼ均一な流速分布で吐水口１ｃから吐出される。 Further, as shown in FIG. 6, an opening at the downstream end of each inflow flow path 12a can be seen from the gap between the notch 30c at the upper end of the tubular portion 30b and the downward wall surface 12e. That is, a part of the projection surface of the inflow flow path 12a (cross section of the flow path of the water pipe 10) in the downstream direction interferes with the rising wall surface 12d (FIG. 4) and the tubular portion 30b of the spout forming member 30. However, the remaining portion does not interfere with these and is located in the gap between the notch 30c and the downward wall surface 12e. Therefore, a part of the hot water that has flowed from each water pipe 10 into the water discharge portion forming member 12 through each inflow flow path 12a becomes a "dispersed wall surface" such as a rising wall surface 12d or an outer peripheral surface of the tubular portion 30b. Although they collide, the remaining portion flows directly into the tubular portion 30b without directly colliding with them. Therefore, the hot water guided from each water pipe 10 is dispersed without excessively decreasing the flow velocity, maintains an appropriate flow velocity, and is discharged from the spout 1c with a substantially uniform flow velocity distribution.

次に、図７を参照して、本発明の実施形態の吐水装置１の製造方法を説明する。
図７は、吐水装置１の製造方法において、第２外観部品８ｂと第３外観部品８ｃを接合する手順を模式的に示す説明図である。 Next, a method of manufacturing the water discharge device 1 according to the embodiment of the present invention will be described with reference to FIG. 7.
FIG. 7 is an explanatory diagram schematically showing a procedure for joining the second appearance component 8b and the third appearance part 8c in the manufacturing method of the water discharge device 1.

上述したように、本実施形態の吐水装置１における吐水装置本体８は、第２外観部品８ｂ、第３外観部品８ｃ及び第４外観部品８ｄを溶接して前側外観部品９を形成し、この前側外観部品９を第１外観部品８ａと結合することにより構成されている（図３）。まず、準備工程として、ステンレス製の薄板から形成された第１乃至第４外観部品を準備する。 As described above, the water discharge device main body 8 in the water discharge device 1 of the present embodiment is formed by welding the second appearance part 8b, the third appearance part 8c, and the fourth appearance part 8d to form the front appearance part 9, and the front side thereof. It is configured by combining the appearance component 9 with the first appearance component 8a (FIG. 3). First, as a preparatory step, first to fourth appearance parts formed from a thin stainless steel plate are prepared.

次に、図７（ａ）に示すように第２外観部品８ｂ及び第３外観部品８ｃを準備し、図７（ｂ）に示すように、第２外観部品８ｂの下側の端面と、第３外観部品８ｃの上側の端面を互いに突き合わせる。次に、図７（ｃ）に示すように、接合工程として、第２外観部品８ｂの端面と、第３外観部品８ｃの端面の突き合わせ部分を溶接して接合する。図７（ｃ）に示すように、第２外観部品８ｂと第３外観部品８ｃを溶接により接合すると、その接合部３４にはビード３４ａが形成される。同様に、第２外観部品８ｂの上端と第４外観部品８ｄの後端も、それらの端面同士を突き合わせ、溶接により接合する。これにより、前側外観部品９が形成される。さらに、第３外観部品８ｃの底面にベース部材１８の平板部１８ａ（図３）を嵌め込み、それらの間を溶接により接合する。なお、本実施形態においては、レーザ溶接により外観部品同士を接合しているが、各外観部品を鑞付等、他の方法によって接合することもできる。 Next, as shown in FIG. 7A, the second appearance part 8b and the third appearance part 8c are prepared, and as shown in FIG. 7B, the lower end surface of the second appearance part 8b and the second appearance part 8b. 3 The upper end faces of the exterior parts 8c are butted against each other. Next, as shown in FIG. 7C, as a joining step, the end face of the second appearance component 8b and the abutting portion of the end face of the third appearance part 8c are welded and joined. As shown in FIG. 7C, when the second appearance component 8b and the third appearance part 8c are joined by welding, a bead 34a is formed at the joint portion 34. Similarly, the upper end of the second appearance component 8b and the rear end of the fourth appearance component 8d are also joined by welding their end faces abutting each other. As a result, the front appearance component 9 is formed. Further, the flat plate portion 18a (FIG. 3) of the base member 18 is fitted to the bottom surface of the third appearance component 8c, and the flat plate portions 18a (FIG. 3) are joined by welding. In the present embodiment, the appearance parts are joined by laser welding, but the appearance parts can also be joined by other methods such as brazing.

次に、図７（ｄ）に示すように、研磨工程として、第２外観部品８ｂと第３外観部品８ｃの接合部３４に研磨加工を施し、接合工程において形成されたビード３４ａを除去すると共に、接合部３４を平滑にする。同様に、他の接合部、及び接合により構成された中間部品（第２乃至第４外観部品及びベース部材１８を接合したもの）全体を平滑に研磨して、前側外観部品９を完成させる（図７（ｅ））。 Next, as shown in FIG. 7D, as a polishing step, the joint portion 34 of the second appearance component 8b and the third appearance part 8c is polished to remove the bead 34a formed in the joining step. , Smooth the joint 34. Similarly, the other joints and the entire intermediate part (the second to fourth appearance parts and the base member 18 are joined) composed of the joints are smoothly polished to complete the front appearance part 9 (FIG. 7 (e)).

ここで、平滑に仕上げられた表面では、その表面に存在する凹凸が極めて微細な場合でも、光の反射の不連続性等により使用者には凹凸の存在が容易に認識されてしまう。このため、接合部３４に入念な研磨加工を施し、表面を平滑に仕上げた場合でも、接合部３４を完全な連続面のように仕上げることは困難である。しかしながら、本実施形態においては、第２外観部品８ｂと第３外観部品８ｃの接合部３４は、吐水装置本体８が基端部で屈曲している部分の近傍に設けられているため、接合部３４に残る僅かな凹凸が目立ちにくくなっている。 Here, on a smooth-finished surface, even if the unevenness existing on the surface is extremely fine, the existence of the unevenness is easily recognized by the user due to the discontinuity of light reflection or the like. Therefore, even if the joint portion 34 is carefully polished to make the surface smooth, it is difficult to finish the joint portion 34 as if it were a completely continuous surface. However, in the present embodiment, the joint portion 34 of the second appearance component 8b and the third appearance component 8c is provided in the vicinity of the portion where the water discharge device main body 8 is bent at the base end portion, and thus is a joint portion. The slight unevenness remaining on 34 is less noticeable.

即ち、図７（ｅ）に示すように、第３外観部品８ｃは側面視において所定の半径で湾曲した湾曲面を有する一方、第２外観部品８ｂの下端部は側面視において直線の表面を有する。このように、第２外観部品８ｂと第３外観部品８ｃの接合部３４は湾曲部から直線部への移行部分に設けられている。このような部分では、湾曲部から直線部への移行により光の反射状態が変化する。このため、接合部３４に残存する僅かな凹凸による光の反射の不連続性が、湾曲部から直線部への移行による光の反射の変化の中に隠されてしまい、使用者には僅かな凹凸による光の反射の不連続性が認識されにくい。なお、第２外観部品８ｂと第４外観部品８ｄの接合部は側面視において直線同士の接合であるが、この接合部は吐水装置本体８の水平部分の下側に位置するため、使用者の目につきにくく、吐水装置１の外観が損なわれることはない。また、第３外観部品８ｃとベース部材１８の接合部は、吐水装置本体８の底面にあり、使用者から見ることはできない。 That is, as shown in FIG. 7 (e), the third external component 8c has a curved surface curved with a predetermined radius in the side view, while the lower end portion of the second external component 8b has a straight surface in the side view. .. As described above, the joint portion 34 of the second appearance component 8b and the third appearance component 8c is provided at the transition portion from the curved portion to the straight portion. In such a portion, the light reflection state changes due to the transition from the curved portion to the straight portion. For this reason, the discontinuity of light reflection due to the slight unevenness remaining in the joint portion 34 is hidden in the change in light reflection due to the transition from the curved portion to the straight portion, which is slight to the user. It is difficult to recognize the discontinuity of light reflection due to unevenness. The joint portion between the second appearance component 8b and the fourth appearance component 8d is a joint between straight lines in a side view, but since this joint portion is located below the horizontal portion of the water discharge device main body 8, the user It is hard to see and the appearance of the water discharge device 1 is not spoiled. Further, the joint portion between the third appearance component 8c and the base member 18 is on the bottom surface of the water discharge device main body 8 and cannot be seen by the user.

このように、研磨加工により前側外観部品９が完成された後、図３に示すように、２本の通水管１０を接続した吐水部形成部材１２を前側外観部品９の上面から背面に沿うように配置する。さらに、上部補強板１４及び下部補強板１６を各通水管１０の後ろ側の所定の箇所に配置する。次に、各部品を組み付けた前側外観部品９の上面から背面に沿うように第１外観部品８ａを配置し、第１外観部品８ａを前側外観部品９にスナップ留めすることにより吐水装置１が完成する。 In this way, after the front exterior component 9 is completed by polishing, as shown in FIG. 3, the water discharge portion forming member 12 connecting the two water pipes 10 is aligned from the upper surface to the back surface of the front exterior component 9. Place in. Further, the upper reinforcing plate 14 and the lower reinforcing plate 16 are arranged at predetermined positions on the rear side of each water pipe 10. Next, the first appearance part 8a is arranged along the back surface from the upper surface of the front appearance part 9 to which each part is assembled, and the first appearance part 8a is snapped to the front appearance part 9 to complete the water discharge device 1. To do.

次に、本発明の実施形態による吐水装置１の作用を説明する。
まず、使用者が、洗面ボウル２横に配置された操作部６（図１）を操作すると、水用電磁弁（図示せず）及び湯用電磁弁（図示せず）が開弁され、これらを通過した水及び湯がサーモ水栓（図示せず）により適温に混合される。サーモ水栓（図示せず）から流出した湯水は２つに分岐され、同一の給水源からの同質の湯水が、吐水装置１の下端から２本の通水管１０に夫々流入する。各通水管１０によって導かれた湯水は、吐水部形成部材１２（図４及び図５）の流入流路１２ａに夫々流入する。 Next, the operation of the water discharge device 1 according to the embodiment of the present invention will be described.
First, when the user operates the operation unit 6 (FIG. 1) arranged beside the washbasin 2, the water solenoid valve (not shown) and the hot water solenoid valve (not shown) are opened, and these are opened. The water and hot water that have passed through the water and hot water are mixed at an appropriate temperature by a thermo-faucet (not shown). The hot water flowing out from the thermo-faucet (not shown) is branched into two, and the same quality hot water from the same water supply source flows into the two water pipes 10 from the lower end of the water discharge device 1. The hot water guided by each water pipe 10 flows into the inflow flow path 12a of the water discharge portion forming member 12 (FIGS. 4 and 5), respectively.

流入流路１２ａに流入した湯水は、それらの下流端において分散壁面である立上り壁面１２ｄ（図４）に衝突して左右に分散される（図５の矢印）。また、湯水の流れは、吐水口形成部材３０の切欠部３０ｃの表面（分散壁面）によって上方に向けられ、吐水部形成部材１２の内部の下向き壁面１２ｅに衝突して分散されながら吐水口形成部材３０の筒状部３０ｂ中に流入する（図４の矢印）。また、各流入流路１２ａから流出した湯水の一部は、立上り壁面１２ｄや切欠部３０ｃの表面に直接衝突することなく筒状部３０ｂの中に流入する。筒状部３０ｂの中に流入した湯水は、筒状部３０ｂの内壁面に衝突しながら、整流網２８を通って、下方に向けて開口した吐水口１ｃから吐出される。このように、２本の通水管１０から供給された湯水は、吐水部形成部材１２の内部で衝突及び分散を繰り返しながら流速分布が均一にされる。このため、細長い吐水口１ｃから吐出される湯水は、透明感のある幅広の滝状（薄膜状）の整流となって流下する。 The hot water that has flowed into the inflow flow path 12a collides with the rising wall surface 12d (FIG. 4), which is a dispersion wall surface, and is dispersed to the left and right at their downstream ends (arrows in FIG. 5). Further, the flow of hot water is directed upward by the surface (dispersed wall surface) of the notch 30c of the spout forming member 30, collides with the downward wall surface 12e inside the spout forming member 12, and is dispersed while being dispersed. It flows into the tubular portion 30b of 30 (arrow in FIG. 4). Further, a part of the hot water flowing out from each inflow flow path 12a flows into the tubular portion 30b without directly colliding with the surface of the rising wall surface 12d or the notch portion 30c. The hot water that has flowed into the tubular portion 30b is discharged from the spout 1c that opens downward through the rectifying net 28 while colliding with the inner wall surface of the tubular portion 30b. In this way, the hot water supplied from the two water pipes 10 has a uniform flow velocity distribution while repeating collision and dispersion inside the water discharge portion forming member 12. Therefore, the hot water discharged from the elongated spout 1c flows down as a transparent, wide waterfall-shaped (thin film-shaped) rectifier.

本発明の実施形態の吐水装置１によれば、吐水装置本体８の内部に湯水を導く通水管１０が挿通されているので、吐水装置本体８を金属で形成した場合にも、通水管１０内の湯水から吐水装置本体８への熱伝導が抑制され、吐水装置本体８が過熱して、これに触れた使用者に不快感を与えるのを防止することができる。また、本実施形態の吐水装置１によれば、吐水装置本体８の内部に同一の給水源から供給された同質の湯水が流れる通水管１０が２本並べて挿通されているので、細い通水管１０を使用した場合でも吐水口１ｃから十分な流量の吐水を得ることができる。また、吐水装置本体８の内部に通水管１０を２本配置することにより、円形断面の通水管１０を使用した場合でも、薄型扁平な断面形状を有する吐水装置本体８の内部に、十分な流路断面積を確保することができ、十分な吐水流量を得ることができる。 According to the water discharge device 1 of the embodiment of the present invention, since the water pipe 10 for guiding hot water is inserted inside the water discharge device main body 8, even when the water discharge device main body 8 is made of metal, the inside of the water pipe 10 The heat conduction from the hot water to the water discharge device main body 8 is suppressed, and it is possible to prevent the water discharge device main body 8 from overheating and causing discomfort to the user who touches the water discharge device main body 8. Further, according to the water discharge device 1 of the present embodiment, two water pipes 10 through which hot water of the same quality supplied from the same water supply source flows are inserted side by side inside the water discharge device main body 8, so that the thin water pipe 10 is inserted. A sufficient flow rate of water can be obtained from the spout 1c even when the water spout 1c is used. Further, by arranging two water pipes 10 inside the water discharge device main body 8, even when a water pipe 10 having a circular cross section is used, a sufficient flow rate is provided inside the water discharge device main body 8 having a thin and flat cross-sectional shape. The road cross-sectional area can be secured, and a sufficient discharge water flow rate can be obtained.

また、本実施形態の吐水装置１によれば、２本の通水管１０から導かれた湯水を合流させて吐水口１ｃに導く接続通水路（吐水部形成部材１２内の水路）に、湯水を分散させる分散部（立上り壁面１２ｄ、下向き壁面１２ｅ、切欠部３０ｃの傾斜した表面）が形成されているので（図４）、細長い吐水口１ｃに導かれる湯水の流速を均等に近付けることができ、吐水口から美観に優れた滝状（膜状）の吐水を得ることができる。 Further, according to the water discharge device 1 of the present embodiment, the hot water is supplied to the connecting water passage (the water channel in the water discharge portion forming member 12) that joins the hot water guided from the two water pipes 10 and leads to the water discharge port 1c. Since the dispersion portion (rising wall surface 12d, downward wall surface 12e, inclined surface of the notch 30c) is formed to disperse (FIG. 4), the flow velocity of the hot water guided to the elongated spout 1c can be evenly approached. A waterfall-like (membrane-like) spout with excellent aesthetics can be obtained from the spout.

さらに、本実施形態の吐水装置１によれば、分散部として、接続通水路の下側壁面から上方に向けて立ち上がる立上り壁面１２ｄを備えているので（図４）、複数の通水管１０から流出した湯水は立上り壁面１２ｄに衝突して上方に向けられた後、下方に向けて開口した吐水口１ｃから吐出される。これにより、狭いスペースで流れを分散させ、流速を均等に近付けることができるので、美観に優れた滝状（膜状）の吐水を得るための分散部をコンパクトに構成することができる。 Further, according to the water discharge device 1 of the present embodiment, since the water discharge device 1 is provided with a rising wall surface 12d that rises upward from the lower side wall surface of the connecting water passage as a dispersion portion (FIG. 4), it flows out from the plurality of water pipes 10. The generated hot water collides with the rising wall surface 12d and is directed upward, and then discharged from a spout 1c opened downward. As a result, the flow can be dispersed in a narrow space and the flow velocity can be evenly approached, so that the dispersion portion for obtaining a waterfall-like (membrane-like) water discharge having an excellent aesthetic appearance can be compactly configured.

また、本実施形態の吐水装置１によれば、筒状部３０ｂの切欠部３０ｃに傾斜した表面が形成され、これにより上方に向けられた湯水の流れが下向き壁面１２ｅに衝突して吐出されるので（図４）、各通水管１０から流出した湯水は、まず切欠部３０ｃの表面に衝突して分散された後、さらに下向き壁面１２ｅに衝突して分散される。このため、各通水管１０から流出した湯水は、二段階に分散され、吐水口１ｃから吐出される湯水の流速をさらに均等に近付けることができる。 Further, according to the water discharge device 1 of the present embodiment, an inclined surface is formed in the cutout portion 30c of the tubular portion 30b, whereby the flow of hot water directed upward collides with the downward wall surface 12e and is discharged. Therefore (FIG. 4), the hot water flowing out from each water pipe 10 first collides with the surface of the notch 30c and is dispersed, and then further collides with the downward wall surface 12e and is dispersed. Therefore, the hot water flowing out from each water pipe 10 is dispersed in two stages, and the flow velocity of the hot water discharged from the spout 1c can be made closer evenly.

さらに、本実施形態の吐水装置１によれば、各通水管１０の投影面の一部が干渉するように分散壁面（立上り壁面１２ｄ、切欠部３０ｃの傾斜した表面）が形成されているので（図６）、各通水管１０から吐出された湯水の一部は分散壁面に衝突する一方、残りの部分は分散壁面に直接衝突せず分散壁面を越えて流れる。本実施形態の吐水装置１によれば、各通水管１０から吐出された湯水の一部を分散壁面に衝突させているので、湯水の分散性と流速を適切にバランスさせることができ、美観に優れた滝状（膜状）の吐水を得ることができる。 Further, according to the water discharge device 1 of the present embodiment, the dispersed wall surface (rising wall surface 12d, inclined surface of the cutout portion 30c) is formed so that a part of the projection surface of each water pipe 10 interferes ( FIG. 6), a part of the hot water discharged from each water pipe 10 collides with the dispersed wall surface, while the remaining portion does not directly collide with the dispersed wall surface and flows over the dispersed wall surface. According to the water discharge device 1 of the present embodiment, since a part of the hot water discharged from each water pipe 10 collides with the dispersed wall surface, the dispersibility and the flow velocity of the hot water can be appropriately balanced, which is aesthetically pleasing. An excellent waterfall-like (membrane-like) water discharge can be obtained.

以上、本発明の好ましい実施形態を説明したが、上述した実施形態に種々の変更を加えることができる。特に、上述した実施形態においては、吐水装置本体の内部には２本の通水管が挿通されていたが、３本以上の通水管を設けることもできる。 Although the preferred embodiment of the present invention has been described above, various modifications can be made to the above-described embodiment. In particular, in the above-described embodiment, two water pipes are inserted inside the water discharge device main body, but three or more water pipes can be provided.

また、上述した実施形態においては、吐水口形成部材３０の筒状部３０ｂに形成された分散壁面である切欠部３０ｃの表面は直線状に形成されていたが（図６）、変形例として、切欠部の高さが各部で異なるように本発明を構成することもできる。図８は、このように構成された変形例を示す図６と同様の断面図である。図８に示す変形例においては、吐水口形成部材３０の切欠部４０の上縁が、流入流路１２ａの出口と対向する部分では高く、その両側では低く形成されている。即ち、本変形例においては、切欠部４０の上縁が、各流入流路１２ａ（通水管１０の流路断面）の下流方向への投影面と干渉する部分では高く、干渉しない部分では低く形成されている。 Further, in the above-described embodiment, the surface of the notch portion 30c, which is the dispersion wall surface formed in the tubular portion 30b of the spout forming member 30, is formed in a straight line (FIG. 6), but as a modified example, The present invention can also be configured such that the height of the notch is different for each portion. FIG. 8 is a cross-sectional view similar to FIG. 6 showing a modified example configured in this way. In the modified example shown in FIG. 8, the upper edge of the notch 40 of the spout forming member 30 is formed high at the portion facing the outlet of the inflow flow path 12a and low at both sides thereof. That is, in this modification, the upper edge of the notch 40 is formed high in the portion that interferes with the projection surface in the downstream direction of each inflow flow path 12a (cross section of the flow path of the water pipe 10), and is formed low in the portion that does not interfere. Has been done.

このため、各流入流路１２ａから流出した湯水は、切欠部４０の上縁の高い部分に衝突し、その両側の低い部分に広がるように分散される。即ち、切欠部４０の上縁の、各流入流路１２ａの投影面と干渉しない部分では、切欠部４０の上縁と下向き壁面１２ｅとの間の隙間が大きくなるため、衝突した湯水は、隙間が大きい部分に分散されやすくなり、分散性を向上させることができる。 Therefore, the hot water flowing out from each inflow flow path 12a collides with the high portion of the upper edge of the notch portion 40 and is dispersed so as to spread to the low portions on both sides thereof. That is, in the portion of the upper edge of the notch portion 40 that does not interfere with the projection surface of each inflow flow path 12a, the gap between the upper edge of the notch portion 40 and the downward wall surface 12e becomes large, so that the hot water that collides is a gap. Is easily dispersed in a large portion, and the dispersibility can be improved.

さらに、上述した実施形態においては、第２外観部品８ｂと第３外観部品８ｃは同一の厚さを有し、これらが突き合わせられ溶接されていたが、変形例として、溶接される外観部品の板厚は異なっていても良い。図９に示す変形例においては、まず、第２外観部品５０ｂと、第２外観部品５０ｂよりも板厚が厚い第３外観部品５０ｃが準備され（図９（ａ））、これらがその端面において突き合わせられ（図９（ｂ））、溶接される（図９（ｃ））。即ち、本変形例においては、湾曲部を形成している第３外観部品５０ｃが直線部を形成している第２外観部品５０ｂよりも板厚が厚く形成されている。この溶接により形成された接合部５２にはビード５２ａが形成されると共に、板厚の相違のために段差５４が形成される。ここで、接合部５２に形成される段差５４は、第２外観部品５０ｂよりも第３外観部品５０ｃの方が板厚が厚いため、常に第３外観部品５０ｃ側が突出した段差５４となる。 Further, in the above-described embodiment, the second appearance part 8b and the third appearance part 8c have the same thickness and are butt-welded, but as a modification, the plate of the appearance part to be welded. The thickness may be different. In the modified example shown in FIG. 9, first, a second appearance part 50b and a third appearance part 50c having a thickness thicker than that of the second appearance part 50b are prepared (FIG. 9A), and these are formed on the end faces thereof. They are butted (FIG. 9 (b)) and welded (FIG. 9 (c)). That is, in this modification, the third appearance component 50c forming the curved portion is formed to be thicker than the second appearance part 50b forming the straight portion. A bead 52a is formed in the joint portion 52 formed by this welding, and a step 54 is formed due to a difference in plate thickness. Here, the step 54 formed in the joint portion 52 is a step 54 in which the third appearance component 50c side always protrudes because the plate thickness of the third appearance part 50c is thicker than that of the second appearance part 50b.

次いで、研磨工程において、図９（ｄ）に示すように、接合部５２に形成されたビード５２ａを除去すると共に、第３外観部品５０ｃの接合部５２近傍を僅かに削って段差５４を除去する。また、研磨工程において段差５４を除去する際、削られた段差５４の部分が第３外観部品５０ｃの湾曲面と滑らかに連続するように第３外観部品５０ｃの表面を研磨して研磨工程を終了する（図９（ｅ））。 Next, in the polishing step, as shown in FIG. 9D, the bead 52a formed in the joint portion 52 is removed, and the vicinity of the joint portion 52 of the third appearance component 50c is slightly scraped to remove the step 54. .. Further, when the step 54 is removed in the polishing step, the surface of the third appearance part 50c is polished so that the scraped step portion 54 is smoothly continuous with the curved surface of the third appearance part 50c, and the polishing step is completed. (Fig. 9 (e)).

第２、第３外観部品を突き合わせて溶接により接合する場合、各外観部品の板厚が同じであると、溶接における接合誤差により僅かに第２外観部品側が突出する場合と、僅かに第３外観部品側が突出する場合が存在する。ここで、湾曲部において接合されている第３外観部品側が突出した場合には、第３外観部品の接合部近傍を削ることにより、容易に接合部を第３外観部品の湾曲面と滑らかに連続させることができる。一方、第２外観部品側が突出した場合には、第２外観部品を削って接合部を滑らかに連続させる必要があるが、このためには第２外観部品の直線部を長い距離に亘って削ることが要求され、接合部を滑らかに連続させるための研磨量が多くなる。 When the second and third appearance parts are butted and joined by welding, if the plate thickness of each appearance part is the same, the second appearance part side slightly protrudes due to the joining error in welding, and the third appearance part slightly protrudes. There are cases where the component side protrudes. Here, when the third external component side that is joined in the curved portion protrudes, the joint portion is easily continuously connected to the curved surface of the third external component by scraping the vicinity of the joint portion of the third external component. Can be made to. On the other hand, when the second appearance component side protrudes, it is necessary to scrape the second appearance component to make the joints smoothly continuous. For this purpose, the straight portion of the second appearance component is scraped over a long distance. This is required, and the amount of polishing for smoothly continuing the joint portion is increased.

本変形例においては、湾曲部において接合されている第３外観部品５０ｃが厚く形成されているので、接合誤差がある場合でも常に第３外観部品５０ｃ側が第２外観部品５０ｂ側よりも突出した段差５４が形成される。このため、研磨工程においては、常に板厚の厚い方の第３外観部品５０ｃを僅かに削って接合部５２を平滑にすれば良く、一律な作業により接合部５２を平滑にすることができる。加えて、本変形例においては、接合工程において接合誤差が発生した場合でも、常に、湾曲部が形成されている第３外観部品５０ｃ側を研磨工程において少量研磨するだけで容易に接合部５２を滑らかに連続させることができる。 In this modified example, since the third appearance component 50c joined at the curved portion is formed thickly, a step in which the third appearance part 50c side always protrudes from the second appearance part 50b side even if there is a joining error. 54 is formed. Therefore, in the polishing step, it is sufficient to always slightly scrape the thicker third appearance component 50c to smooth the joint portion 52, and the joint portion 52 can be smoothed by a uniform operation. In addition, in this modification, even if a joining error occurs in the joining step, the joining portion 52 can be easily formed by simply polishing the third appearance part 50c side on which the curved portion is formed in a small amount in the polishing step. It can be made continuous smoothly.
