Description

本発明は、水栓装置に係り、特に、吐止水を行う水栓装置に関する。   The present invention relates to a faucet device, and more particularly, to a faucet device that performs water discharge.

従来から、吐止水を行う水栓装置として、例えば、特許文献１に記載されているように、単一の操作ハンドルを操作することにより、原水による水吐水、湯吐水、湯水混合吐水、又は、浄水吐水の何れかの吐水モードに切り替えて吐水操作が可能である、いわゆる、シングルレバー式の混合水栓装置が知られている。
このような混合水栓装置は、混合水栓装置本体に内蔵されて給水管及び給湯管が接続されたバルブカートリッジと、混合水栓装置本体に固定されたスパウトを備えている。このスパウトの内部には、バルブカートリッジを通過した原水が直接的に流入する原水側流路が形成されている。また、スパウトの内部には、原水側流路とは独立に、バルブカートリッジから延びる浄水側配管が延びて浄水側流路が形成されており、この浄水側流路には、バルブカートリッジから浄水側流路内に流入した原水を浄化するための浄水カートリッジが設けられている。 Conventionally, as a faucet device that performs spitting water, for example, as described in Patent Document 1, by operating a single operation handle, water sprinkling with raw water, hot water sprinkling water, hot water mixing spitting water, or There is known a so-called single lever type mixed water faucet device that is capable of performing a water discharge operation by switching to one of the water discharge modes of purified water discharge.
Such a mixing faucet device includes a valve cartridge that is built in the mixing faucet body and connected to a water supply pipe and a hot water supply pipe, and a spout fixed to the mixing faucet body. Inside the spout, a raw water side flow path is formed through which the raw water that has passed through the valve cartridge flows directly. Also, inside the spout, a water purification side pipe extending from the valve cartridge is formed independently of the raw water side flow path to form a water purification side flow path. The water purification side flow path is formed from the valve cartridge to the water purification side. A water purification cartridge for purifying the raw water flowing into the flow path is provided.

つぎに、特許文献２に記載されている従来の混合水栓装置では、スパウトの先端部に供給された原水の水路を切り替える切替ユニットと、混合水栓装置本体が設けられる流し台の上面に設置されて原水の処理を行う水処理ユニットとを備え、さらに、この水処理ユニットと切替ユニットとの間に設けられて切替ユニットから水処理ユニットに原水を供給すると共に、水処理ユニットで処理された処理水を切替ユニットへ返送するための、同心状に配置された大径ホースと小径ホースからなる二重ホースを備えている。また、切替ユニットには、原水の流路を切り替える切替レバーが設けられており、この切替レバーを操作することによって、原水をそのまま吐水する流路、原水をシャワー状に吐水する流路、又は原水を切替ユニットより水処理ユニットへ供給する流路の何れかに切り替えて３種類の吐水を行うことができるようになっている。   Next, in the conventional mixing faucet device described in Patent Document 2, the switching unit that switches the water channel of the raw water supplied to the tip portion of the spout and the upper surface of the sink provided with the mixing faucet device main body are installed. And a water treatment unit that treats the raw water, and is further provided between the water treatment unit and the switching unit to supply raw water from the switching unit to the water treatment unit and to treat the water treated by the water treatment unit. It has a double hose consisting of a large diameter hose and a small diameter hose arranged concentrically for returning water to the switching unit. Further, the switching unit is provided with a switching lever for switching the flow path of the raw water. By operating this switching lever, the flow path for discharging the raw water as it is, the flow path for discharging the raw water in a shower form, or the raw water Can be switched to one of the flow paths that supply the water treatment unit from the switching unit to perform three types of water discharge.

また、特許文献３に記載されている従来の混合水栓装置では、高度浄水が流れる小径ホースと無塩素浄水が流れる大径ホースからなる二重ホースを備え、この二重ホースの下流側に設けられたスパウトの先端の吐水部で複数の流路を選択的に切り替えることにより、浄水器からの２種類の洗浄水、又は水栓からの原水の何れかを選択することができるようになっているものも知られている。   In addition, the conventional mixing faucet device described in Patent Document 3 includes a double hose consisting of a small diameter hose through which highly purified water flows and a large diameter hose through which chlorine-free purified water flows, and is provided downstream of the double hose. By selectively switching a plurality of flow paths at the water discharge section at the tip of the spout, it is possible to select either two types of washing water from the water purifier or raw water from the faucet Some are known.

さらに、特許文献４に記載されている従来の混合水栓装置では、水道水が流れる水道水路と、浄水が流れる浄水路と、これら水道水路と浄水路とを区画する仕切り壁を備えた吐出管が開示されている。この吐出管の仕切り壁は、塩化ビニル等の可撓性のある材料で形成されており、水道水路内に水道水が流れるときには、その水圧により仕切り壁が浄水路側へ押圧され、水道水路の断面積が増大することにより水道水路内を大量の水道水が流れることができるようになっている。一方、浄水路内に浄水が流れるときには、仕切り壁が水道水路側へ押圧されて浄水路の断面積が拡大され、大量の浄水が流れるようになっている。   Furthermore, in the conventional mixer tap apparatus described in Patent Document 4, a discharge pipe provided with a tap water channel through which tap water flows, a water purification channel through which purified water flows, and a partition wall that divides the tap water channel and the water purification channel. Is disclosed. The partition wall of the discharge pipe is formed of a flexible material such as vinyl chloride. When tap water flows in the tap water channel, the partition wall is pressed toward the water purification channel by the water pressure, and the tap water channel is disconnected. Due to the increase in area, a large amount of tap water can flow in the tap water channel. On the other hand, when purified water flows in the purified water channel, the partition wall is pressed toward the tap water channel, the cross-sectional area of the purified water channel is expanded, and a large amount of purified water flows.

しかしながら、上述した特許文献１に記載されている従来の混合水栓装置においては、スパウトが混合水栓装置本体に常時固定されており、スパウトの先端の吐水部を混合水栓装置本体から取り外し、使用者側に引き出して使用したりすることができないため、使い勝手が良くないという問題がある。また、互いに独立した原水側流路と浄水側流路が装置内に集約されておらず、混合水栓装置本体からスパウトにかけて内部スペースを要するため、混合水栓装置を小型化するにも限界があるという問題もある。
また、上述した特許文献２及び３に記載されている従来の混合水栓装置では、二重ホースの流路断面積が、二重ホースと同一径の単一ホースの流路断面積に比べて小さくなるため、二重ホースと同一径の単一ホースを用いた場合には、吐水流量が低下してしまうという問題がある。さらに、上述した特許文献２では、使用時には、二重ホースの小径ホース内に形成される内側流路と、小径ホースの外周面と大径ホースの内周面との間に形成される外側流路の双方では、互いに逆方向に水がそれぞれ流れて常時互いの水圧が作用するような構造であり、上述した特許文献３では、二重ホースの下流側のスパウトの先端の吐水部で吐水の種類を切り替え、二重ホースの内側流路と外側流路の双方で常時互いの水圧が作用するような構造であるため、二重ホース内の内側流路や外側流路の流路断面積を適宜変更することができず、スパウトから吐水される吐水の種類にかかわらず一定の吐水流量を確保することが難しいという問題もある。
さらに、上述した特許文献４に記載されている従来の混合水栓装置では、吐出管の仕切り壁の端部（付け根部分）に水道水路や浄水路内の水圧等による繰り返し応力が作用し、破損も生じやすいため、耐久性が低く、吐出管に隣接する周辺部材との接続も難しいという問題がある。 However, in the conventional mixing faucet device described in Patent Document 1 described above, the spout is always fixed to the mixing faucet device body, and the water discharge portion at the tip of the spout is removed from the mixing faucet device body, Since it cannot be pulled out to the user side and used, there is a problem that it is not easy to use. In addition, since the raw water side flow path and the purified water side flow path independent from each other are not integrated in the apparatus and an internal space is required from the mixing faucet body to the spout, there is a limit to downsizing the mixing faucet apparatus. There is also the problem of being.
Moreover, in the conventional mixing faucet device described in Patent Documents 2 and 3 described above, the channel cross-sectional area of the double hose is larger than the channel cross-sectional area of a single hose having the same diameter as the double hose. Therefore, when a single hose having the same diameter as the double hose is used, there is a problem that the water discharge flow rate is reduced. Furthermore, in Patent Document 2 described above, when used, the outer flow formed between the inner flow path formed in the small diameter hose of the double hose and the outer peripheral surface of the small diameter hose and the inner peripheral surface of the large diameter hose. In both of the paths, water flows in opposite directions so that the water pressures are always applied. In Patent Document 3 described above, water is discharged at the water discharge portion at the tip of the spout on the downstream side of the double hose. Since the structure is such that the water pressure always acts on both the inner and outer channels of the double hose, the cross-sectional area of the inner and outer channels in the double hose can be adjusted. There is also a problem that it cannot be changed as appropriate and it is difficult to ensure a constant water discharge flow rate regardless of the type of water discharged from the spout.
Furthermore, in the conventional mixing faucet device described in Patent Document 4 described above, repeated stress due to water pressure or the like in the tap water channel or the water purification channel acts on the end portion (base portion) of the partition wall of the discharge pipe, resulting in damage. Therefore, there is a problem that durability is low and connection with a peripheral member adjacent to the discharge pipe is difficult.

そこで、本発明は、上述した従来技術の問題を解決するためになされたものであり、二重管の上流側で選択的に切り替えた吐水について、二重管内の吐水流路の断面積を確保して一定の吐水流量を確保することができる混合水栓装置を提供することを目的としている。   Therefore, the present invention was made to solve the above-described problems of the prior art, and for the water discharge selectively switched on the upstream side of the double pipe, ensure the cross-sectional area of the water discharge flow path in the double pipe. Therefore, an object of the present invention is to provide a mixing faucet device that can ensure a constant water discharge flow rate.

上記の目的を達成するために、本発明は、吐止水を行う水栓装置であって、水栓装置本体と、この水栓装置本体に内蔵され、その内部に形成される複数の流路のうちから所定の流路を吐水流路として選択して切り替え可能な流路切替部と、上記水栓装置本体から取り外し可能に設けられ且つ上記流路切替部よりも下流に位置する吐水ヘッド部と、上記流路切替部と上記吐水ヘッド部との間に接続された管部材と、を有し、この管部材は、外側管部とその内部にほぼ同心状に配置された内側管部とからなる二重管部を備え、この二重管部は、上記内側管部の内周側に内側吐水流路を形成すると共に、上記内側管部の外周面と上記外側管部の内周面との間に外側吐水流路を形成し、上記内側管部の少なくとも一部の区間は、上記内側吐水流路内又は上記外側吐水流路内の水圧によって弾性変形可能な弾性材料により形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おいては、二重管部のうちの内側管部の内側吐水流路内を水が流れる際には、内側管部の弾性材料で形成された区間（以下「内側管部の弾性区間」）が内側吐水流路内の水圧により半径方向外側に拡張するように弾性変形し、内側管部の内側吐水流路の断面積が増大し、内側管部の外周面と外側管部の内周面との間の外側吐水流路（以下「内側管部の外側吐水流路」）の断面積が減少する。一方、内側管部の外側吐水流路内を水が流れる際には、内側管部の弾性区間が外側吐水流路内の水圧により内側管部が半径方向内側に押圧されるように弾性変形し、内側管部の内側吐水流路の断面積が減少し、内側管部の外側吐水流路の断面積が増大する。これにより、二重管部の上流側の流路切替部で選択的に切り替えた吐水について、内側管部の内側吐水流路を流れる流体又は内側管部の外側吐水流路を流れる流体として選択的に流すことができる。したがって、二重管部の内側吐水流路内の吐水と外側吐水流路内の吐水を互いに混合させることなく、それぞれの吐水流路の断面積を増大させることができ、管部材の下流側の吐水ヘッド部から吐水する際の流量を増大させることができる。 In order to achieve the above object, the present invention is a water faucet device for carrying out spout water, and a water faucet device body and a plurality of flow paths formed in the faucet device body. A flow path switching unit capable of selecting and switching a predetermined flow path as the water discharge flow path, and a water discharge head section detachably provided from the faucet device body and positioned downstream of the flow path switching section And a tube member connected between the flow path switching unit and the water discharge head unit, and the tube member includes an outer tube unit and an inner tube unit disposed substantially concentrically therein. The double pipe portion is formed with an inner water discharge channel on the inner peripheral side of the inner pipe portion, and the outer peripheral surface of the inner pipe portion and the inner peripheral surface of the outer pipe portion. An outer water discharge channel is formed between the inner pipe portion and at least a part of the inner pipe portion. It is characterized by being formed by elastically deformable resilient material by pressure of the outer water discharge flow path.
In the present invention configured as described above, when water flows in the inner water discharge channel of the inner tube portion of the double tube portion, a section formed of an elastic material of the inner tube portion (hereinafter referred to as “inner side”). The elastic section of the pipe part ”) is elastically deformed so as to expand radially outward due to the water pressure in the inner water discharge channel, and the cross-sectional area of the inner water discharge channel of the inner pipe part increases, The cross-sectional area of the outer water discharge channel (hereinafter referred to as “the outer water discharge channel of the inner tube”) between the inner peripheral surface of the outer tube portion is reduced. On the other hand, when water flows in the outer water discharge channel of the inner pipe part, the elastic section of the inner pipe part is elastically deformed so that the inner pipe part is pressed radially inward by the water pressure in the outer water discharge channel. In addition, the cross-sectional area of the inner water discharge channel of the inner pipe part decreases, and the cross-sectional area of the outer water discharge channel of the inner pipe part increases. As a result, the water discharge selectively switched by the flow path switching unit on the upstream side of the double pipe part is selectively used as the fluid flowing through the inner water discharge flow path of the inner pipe part or the fluid flowing through the outer water discharge flow path of the inner pipe part. Can be shed. Therefore, the cross-sectional area of each water discharge channel can be increased without mixing the water discharge in the inner water discharge channel and the water discharge in the outer water discharge channel of the double pipe part, and the downstream side of the pipe member The flow rate when water is discharged from the water discharge head unit can be increased.

このように構成された本発明においては、管部材の二重管部がバルブカートリッジ部の下流側と吐水ヘッド部との間に接続されているため、シングルレバー式の混合水栓装置本体の操作ハンドルによる吐水モードを選択的に切り替えた吐水操作を行うだけで、バルブカートリッジ部から二重管部を経て吐水ヘッド部へ流れる浄水用の原水と非浄水用の原水のそれぞれの流路を二重管部の上流側で容易に選択的に切り替えることができる。また、吐水ヘッド部とこれに接続されている管部材をシングルレバー式の混合水栓装置本体から取り外し、引き出した状態で使用することもできるため、使い勝手もよい。 In the present invention, preferably, the flow path switching unit includes a fixed valve body, a movable valve body slidably provided on the fixed valve body, and an operation unit for operating the movable valve body.

In a state where the lower end portion of the inner steel pipe member 38 and the upper end portion of the inner hose joint 62 are connected by the coupler 60, the flow path formed on the inner peripheral side of the inner hose joint 62 is the inner steel pipe member 38 above it. The non-purified raw water flow path 62a communicates with the non-purified raw water flow path 38a.
Further, between the outer peripheral surface of the coupler 60 and the inner peripheral surface of the relay pipe 58 opposed to the coupler 60, a purified water raw water channel 58a communicating with the purified water raw water channel 36a inside the outer steel pipe member 36 is provided. Is formed.

さらに、中継パイプ５８は、その下端部でインナーホース継手６２とホース部材１６とを接続するための接続部材である。
ホース部材１６は、具体的には、その上端位置するブッシュ７０を備え、さらに、内側から外側に向ってほぼ同心状に配置された、インナーホース７２、アウターホース７４及びフレキチューブ７６を備えている。 Further, the relay pipe 58 is a connection member for connecting the inner hose joint 62 and the hose member 16 at the lower end thereof.
Specifically, the hose member 16 includes a bush 70 positioned at the upper end thereof, and further includes an inner hose 72, an outer hose 74, and a flexible tube 76 that are arranged substantially concentrically from the inside toward the outside. .

ブッシュ７０は、その上端部７０ａが中継パイプ５８の下方側から内部に向けて挿入されて接続されており、ブッシュ７０の上端部７０ａから下方にほぼ円筒状に延びる円筒部７０ｂの外周面には、アウターホース７４が取り付けられている。さらに、このアウターホース７４の外側には、フレキチューブ７６が配置されており、このフレキチューブ７６の上方側の外周面が中継パイプ５８の下方側の内周面に取り付けられている。   The bush 70 has an upper end 70a inserted and connected from the lower side of the relay pipe 58 to the inside, and is connected to the outer peripheral surface of the cylindrical portion 70b extending substantially cylindrically downward from the upper end 70a of the bush 70. An outer hose 74 is attached. Further, a flexible tube 76 is disposed outside the outer hose 74, and an upper outer peripheral surface of the flexible tube 76 is attached to a lower inner peripheral surface of the relay pipe 58.

また、インナーホース継手６２は、ブッシュ７０の円筒部７０ｂの内周側を上下方向に貫くように延びており、このインナーホース継手６２の下端部は、アウターホース７４の内部でインナーホース７２の内周側に挿入されて接続されている。すなわち、インナーホース７２の内周側には、インナーホース継手６２の非浄水用原水流路６２ａと連通する非浄水用原水流路７２ａが形成されている。   Further, the inner hose joint 62 extends so as to penetrate the inner peripheral side of the cylindrical portion 70 b of the bush 70 in the vertical direction, and the lower end portion of the inner hose joint 62 is inside the inner hose 72 inside the outer hose 74. It is inserted and connected on the circumferential side. That is, a non-purified raw water flow path 72 a that communicates with the non-purified raw water flow path 62 a of the inner hose joint 62 is formed on the inner peripheral side of the inner hose 72.

さらに、インナーホース継手６２の外周面とブッシュ７０の円筒部７０ｂの内周面との間には、中継パイプ５８内の浄水用原水流路５８ａと連通する浄水用原水流路７０ｃが形成されている。また、インナーホース７２の外周面とアウターホース７４の内周面との間には、その上方の浄水用原水流路７０ｃと連通する浄水用原水流路７４ａが形成されている。   Furthermore, between the outer peripheral surface of the inner hose joint 62 and the inner peripheral surface of the cylindrical portion 70b of the bush 70, a purified water raw water channel 70c communicating with the purified water raw water channel 58a in the relay pipe 58 is formed. Yes. Further, between the outer peripheral surface of the inner hose 72 and the inner peripheral surface of the outer hose 74, a purified water raw water channel 74a communicating with the upper purified water source channel 70c is formed.

ここで、インナーホース７２は、その内周側の非浄水用原水流路７２ａ内の水圧や、その外周側の浄水用原水流路７４ａ内の水圧により弾性変形可能な弾性材料、例えば、塩化ビニル、シリコーン、フッ素ゴムで形成されている。
例えば、吐水モードが水吐水モード、湯吐水モード、又は湯水混合吐水モードの何れかに設定され、インナーホース７２の内周側の非浄水用原水流路７２ａ内を非浄水用の原水（水、湯、又は混合湯水）が流れる際には、非浄水用原水流路７２ａ内の水圧によりインナーホース７２が半径方向外側に拡張するように弾性変形し、インナーホース７２の内周側の非浄水用原水流路７２ａの断面積が増大し、インナーホース７２の外周側の浄水用原水流路７４ａの断面積が減少するようになっている。
一方、吐水モードが浄水吐水モードに設定され、インナーホース７２の外周側の浄水用原水流路７４ａ内を浄水用の原水が流れる際には、浄水用原水流路７４ａ内の水圧によりインナーホース７２が半径方向内側に押圧されるように弾性変形し、インナーホース７２の内周側の非浄水用原水流路７２ａの断面積が減少し、インナーホース７２の外周側の浄水用原水流路７４ａの断面積が増大するようになっている。 Here, the inner hose 72 is an elastic material that can be elastically deformed by the water pressure in the non-purified raw water flow path 72a on the inner peripheral side or the water pressure in the raw water flow path 74a on the outer peripheral side, such as vinyl chloride. , Silicone and fluoro rubber.
For example, the water discharge mode is set to any one of the water discharge mode, the hot water discharge mode, or the hot water mixed discharge mode, and the non-purified raw water flow path 72a on the inner peripheral side of the inner hose 72 is supplied with non-purified raw water (water, When hot water or mixed hot water flows), the inner hose 72 is elastically deformed so as to expand radially outward due to the water pressure in the non-purified raw water flow path 72a, and the inner hose 72 is used for non-purified water. The cross-sectional area of the raw water flow path 72a is increased, and the cross-sectional area of the purified water raw water flow path 74a on the outer peripheral side of the inner hose 72 is decreased.
On the other hand, when the water discharge mode is set to the purified water discharge mode and the raw water for water purification flows through the raw water passage 74a for water purification on the outer peripheral side of the inner hose 72, the inner hose 72 is caused by the water pressure in the raw water passage 74a for water purification. Are elastically deformed so as to be pressed inward in the radial direction, the cross-sectional area of the non-purified raw water flow path 72a on the inner peripheral side of the inner hose 72 is reduced, and the purified water raw water flow path 74a on the outer peripheral side of the inner hose 72 is reduced. The cross-sectional area increases.

また、アウターホース７４の外周面は、補強層により覆われており、アウターホース７４の内部の非浄水用原水流路７２ａ内や浄水用原水流路７４ａ内で大きな水圧が作用したとしても、アウターホース７４内の流路断面が半径方向外側に所定以上に拡張することを防ぐことができるようになっており、アウターホース７４が破裂する等の損傷を防ぐことができるようになっている。   Further, the outer peripheral surface of the outer hose 74 is covered with a reinforcing layer, and even if a large water pressure is applied in the non-purified raw water flow path 72 a or the purified water raw water flow path 74 a inside the outer hose 74, The cross section of the flow path in the hose 74 can be prevented from expanding beyond the radial direction beyond a predetermined value, and damage such as the outer hose 74 rupturing can be prevented.

さらに、フレキチューブ７６は、ステンレス等の材料からなる金属製の可撓性ホース部材である。このフレキチューブ７６の内周面とアウターホース７４の外周面との間には、ある程度の隙間７８が形成されているが、この隙間７８は、吐水ヘッド部８を混合水栓装置本体１０の吐水ヘッド取付部１４から取り外して使用した場合に、フレキチューブ７６の曲げや引張りによる弾性変形等、可撓性の自由度を持たせるためのものであり、隙間７８は液密にされているため、非浄水用の原水や浄水用の原水が流れるための流路とはなっていない。   Furthermore, the flexible tube 76 is a metal flexible hose member made of a material such as stainless steel. A certain amount of gap 78 is formed between the inner peripheral surface of the flexible tube 76 and the outer peripheral surface of the outer hose 74, and this gap 78 allows the water discharge head unit 8 to discharge water from the mixing faucet body 10. When used by removing from the head mounting portion 14, the flexible tube 76 is provided with a degree of flexibility such as elastic deformation caused by bending or pulling, and the gap 78 is liquid-tight. It is not a flow path for non-purified raw water or purified water.

つぎに、図１２及び図１３に示すように、吐水ヘッド部８は、外側ケーシング部材９６の内側に設けられた内側ケーシング部材９８と、この内側ケーシング部材９８の内部に設けられた概ね円筒形状の浄水カートリッジ１００とを備えている。
また、内側ケーシング部材９８の外周面と外側ケーシング部材９６の内周面との間には、内側継手部材９０の非浄水用原水流路９０ａの下流側と連通する非浄水用原水流路１０２が形成されている。
一方、内側ケーシング部材９８の内周面と浄水カートリッジ１００の外周面との間には、内側継手部材９０の外周面と外側継手部材８８の内周面との間の浄水用原水流路９０ｂの下流側と連通する浄水用原水流路１０４が非浄水用原水流路１０２から独立して形成されている。この浄水用原水流路１０４内の浄水用原水は、その内側の浄水カートリッジ１００の中を通過することにより浄化された後に、浄水として吐水部８ａ側へ流れるようになっている。
また、非浄水用原水流路１０２内の非浄水用原水は、浄水カートリッジ１００を通過することなく、浄化されていない原水（水、湯、又は混合湯水）のままで吐水部８ａ側へ流れるようになっている。 Next, as shown in FIGS. 12 and 13, the water discharge head portion 8 includes an inner casing member 98 provided inside the outer casing member 96 and a substantially cylindrical shape provided inside the inner casing member 98.

Further, between the outer peripheral surface of the inner casing member 98 and the inner peripheral surface of the outer casing member 96, there is a non-purified raw water flow channel 102 communicating with the downstream side of the non-purified raw water flow channel 90 a of the inner joint member 90. Is formed.
On the other hand, between the inner peripheral surface of the inner casing member 98 and the outer peripheral surface of the water purification cartridge 100, the raw water flow path 90b for water purification between the outer peripheral surface of the inner joint member 90 and the inner peripheral surface of the outer joint member 88 is provided. The purified water raw water flow path 104 communicating with the downstream side is formed independently of the non-purified raw water flow path 102. The purified water in the purified water flow path 104 is purified by passing through the inside of the purified water cartridge 100 and then flows to the water discharger 8a as purified water.
In addition, the non-purified raw water in the non-purified raw water flow path 102 flows to the water discharger 8a side without passing through the water purification cartridge 100 as it is without being purified (water, hot water, or mixed hot water). It has become.

つぎに、図１３に示すように、吐水ヘッド部８の吐水部８ａの内部には、ストレート吐水用の吐水流路１０６及びシャワー吐水用の吐水流路１０８がそれぞれ形成されている。
ストレート吐水用の吐水流路１０６は、切替スイッチ８ｂによりストレート吐水モードが設定されている場合に、吐水ヘッド部８内の非浄水用原水流路１０２を流れた非浄水用原水（水、湯、若しくは混合湯水）、又は、吐水ヘッド部８内の浄水用原水流路１０４から浄水カートリッジ１００を通過した浄水が流れ込み、その下流側でストレート状に吐水させる流路となっている。このとき、シャワー吐水用の吐水流路１０８は、切替スイッチ８ｂの切替弁（図示せず）により閉鎖され、吐水が流入しないようになっている。
一方、シャワー吐水用の吐水流路１０８は、切替スイッチ８ｂによりシャワー吐水モードが設定されている場合に、吐水ヘッド部８内の非浄水用原水流路１０２を流れた非浄水用原水（水、湯、又は混合湯水）が流れ込み、その下流側でシャワー状に吐水させる流路となっている。このとき、ストレート吐水用の吐水流路１０６は、切替スイッチ８ｂの切替部材（図示せず）により閉鎖され、吐水が流入しないようになっている。 Next, as shown in FIG. 13, a water discharge channel 106 for straight water discharge and a water discharge channel 108 for shower water discharge are formed inside the water discharge unit 8 a of the water discharge head unit 8.
When the straight water discharge mode is set by the changeover switch 8b, the water discharge passage 106 for straight water discharge is supplied with non-purified raw water (water, hot water, hot water) flowing through the non-purified raw water flow channel 102 in the water discharge head unit 8. (Or mixed hot water), or purified water that has passed through the purified water cartridge 100 flows from the purified water flow path 104 in the water discharge head portion 8 and is a flow path that discharges water straight in the downstream side. At this time, the water discharge channel 108 for shower water discharge is closed by a switching valve (not shown) of the changeover switch 8b so that the water discharge does not flow in.
On the other hand, when the shower water discharge mode is set by the changeover switch 8b, the water discharge flow path 108 for shower water discharge is supplied with non-purified raw water (water, water) that flows through the non-purified raw water flow path 102 in the water discharge head unit 8. Hot water or mixed hot water) flows in, and forms a flow path for discharging water in a shower-like manner on the downstream side. At this time, the water discharge channel 106 for straight water discharge is closed by a switching member (not shown) of the changeover switch 8b so that the water discharge does not flow in.

また、浄水カートリッジ１００よりも下流側に形成されて浄水カートリッジ１００を通過した浄水が流れる浄水流路１１０は、切替スイッチ８ｂの操作位置にかかわらず、吐水部８ａのストレート吐水用の吐水流路１０６と常時連通しており、シャワー吐水用の吐水流路１０８とは常時連通しない構造となっている。これにより、操作ハンドル６を浄水吐水モード（図８の（ａ）及び（ｂ）参照）に設定した状態で吐水ヘッド８の切替スイッチ８ｂをシャワー吐水モードに設定したとしても、シャワー状の浄水吐水は行われずに、ストレート状の浄水吐水のみが行われるようになっている。
なお、図１３では、浄水流路１１０を流れる浄水の流れＦ３を矢印で示している。 Further, the water purification passage 110 formed downstream of the water purification cartridge 100 and through which the purified water passes through the water purification cartridge 100 flows, regardless of the operation position of the changeover switch 8b. The water discharge channel 108 for shower water discharge is not always in communication. Thereby, even if the changeover switch 8b of the water discharge head 8 is set to the shower water discharge mode in a state where the operation handle 6 is set to the water discharge mode (see (a) and (b) of FIG. 8), the shower-like water discharge It is not performed, and only straight water purification water discharge is performed.
In addition, in FIG. 13, the flow F3 of the purified water which flows through the purified water flow path 110 is shown by the arrow.

つぎに、図１〜図１４を参照して、上述した本発明の一実施形態による水栓装置１の動作（作用）について説明する。
図１４の（ａ）は、本発明の一実施形態による水栓装置の吐水ヘッド部における原水ストレート吐水モードの吐水動作を概略的に説明した図であり、図１４の（ｂ）は、本発明の一実施形態による水栓装置の吐水ヘッド部における原水シャワー吐水モードの吐水動作を概略的に説明した図であり、図１４の（ｃ）は、本発明の一実施形態による水栓装置の吐水ヘッド部における浄水ストレート吐水モードの吐水動作を概略的に説明した図である。 Next, the operation (action) of the faucet device 1 according to the embodiment of the present invention described above will be described with reference to FIGS.
(A) of FIG. 14 is the figure which demonstrated schematically the water discharging operation | movement of the raw | natural water straight water discharging mode in the water discharging head part of the faucet device by one Embodiment of this invention, (b) of FIG. 14 is this invention. FIG. 14 is a diagram schematically illustrating the water discharge operation in the raw water shower water discharge mode in the water discharge head unit of the water faucet device according to the embodiment of FIG. 14, and FIG. It is the figure which demonstrated schematically the water discharging operation | movement of the purified water straight water discharging mode in a head part.

まず、図１４の（ａ）に示すように、原水ストレート吐水モードとは、吐水ヘッド８の切替スイッチ８ｂをストレート吐水モードに設定した状態で、操作ハンドル６を水吐水モードの操作位置Ｐ１（図６の（ａ）参照）、湯吐水モードの操作位置Ｐ２（図７の（ａ）参照）、又は湯水混合吐水モードの操作位置Ｐ３（図７の（ａ）参照）のいずれかに設定したときの吐水モードを意味する。
この原水ストレート吐水モードに設定した場合においては、図３、図４、図６の（ａ）及び（ｂ）、並びに図１０に示すように、操作ハンドル６を水吐水モードに設定した場合には、給水管４から供給される非浄水用の原水（水）が、流路形成部材３０の一次側水流路３０ｂから固定弁体２２の一次側水流路２２ｂを通過し、可動弁体２４の一次側流路２４ａ及び二次側流路２４ｂから固定弁体２２の二次側非浄水用原水流路２２ｃを経て流路形成部材３０の二次側非浄水用原水流路３０ｃを通過する。そして、この非浄水用の原水（水）は、図１０〜図１３に示すように、下流側に向って、内側鋼管部材３８内の非浄水用原水流路３８ａ、インナーホース継手６２内の非浄水用原水流路６２ａ、インナーホース７２内の非浄水用原水流路７２ａ、及び内側継手部材９０の非浄水用原水流路９０ａを経て吐水ヘッド部８内の非浄水用原水流路１０２を流れる。そして、吐水ヘッド８の切替スイッチ８ｂの切替弁（図示せず）がストレート吐水用の吐水流路１０６を開放すると共にシャワー吐水用の吐水流路１０８を閉鎖することにより、浄水されていな原水（水）がストレート吐水用の吐水流路１０６を流れ、最終的には、吐水ヘッド部８の吐水部８ａからストレート吐水される。 First, as shown in FIG. 14A, the raw water straight water discharge mode is the operation position P1 (FIG. 14) of the operation handle 6 in the water discharge mode in a state where the changeover switch 8b of the water discharge head 8 is set to the straight water discharge mode. 6 (see (a)), when the operation position P2 in the hot water discharge mode (see (a) in FIG. 7) or the operation position P3 in the hot water mixed discharge mode (see (a) in FIG. 7). Means water discharge mode.
When the raw water straight water discharge mode is set, as shown in FIGS. 3, 4, 6 (a) and (b) and FIG. 10, the operation handle 6 is set to the water discharge mode. The raw water (water) for non-purification supplied from the water supply pipe 4 passes from the primary side water flow path 30b of the flow path forming member 30 to the primary side water flow path 22b of the fixed valve body 22, and is the primary of the movable valve body 24. The secondary side non-purified raw water flow path 30c of the flow path forming member 30 passes through the secondary side non-purified raw water flow path 22c of the fixed valve body 22 from the side flow path 24a and the secondary side flow path 24b. Then, as shown in FIGS. 10 to 13, this non-purified raw water (water) is non-purified raw water flow path 38 a in the inner steel pipe member 38 and non-purified water in the inner hose joint 62, toward the downstream side. The raw water flow path 62 a for purified water, the raw water flow path 72 a for non-purified water in the inner hose 72, and the non-purified raw water flow path 90 a for the inner joint member 90 flow through the non-purified raw water flow path 102 in the water discharge head unit 8. . Then, a switching valve (not shown) of the changeover switch 8b of the water discharge head 8 opens the water discharge passage 106 for straight water discharge and closes the water discharge passage 108 for shower water discharge, so that the raw water that has not been purified ( Water) flows through the water discharge flow path 106 for straight water discharge, and is finally discharged straight from the water discharge portion 8a of the water discharge head portion 8.

同様に、操作ハンドル６を湯吐水モード（図７の（ａ）及び（ｂ）参照）や湯水混合吐水モード（図７の（ａ））に設定した場合についても、流路形成部材３０の二次側非浄水用原水流路３０ｃの上流側から二次側非浄水用原水流路３０ｃ内に流入した非浄水用の原水（湯又は混合湯水）が、図１０〜図１３に示すように、下流側に向って、内側鋼管部材３８内の非浄水用原水流路３８ａ、インナーホース継手６２内の非浄水用原水流路６２ａ、インナーホース７２内の非浄水用原水流路７２ａ、及び内側継手部材９０の非浄水用原水流路９０ａを経て吐水ヘッド部８内の非浄水用原水流路１０２からストレート吐水用の吐水流路１０６を流れ、最終的には、浄水されていな原水（湯又は混合湯水）が吐水ヘッド部８の吐水部８ａからストレート吐水される。   Similarly, in the case where the operation handle 6 is set to the hot water discharge mode (see FIGS. 7A and 7B) and the hot water mixed water discharge mode (FIG. As shown in FIGS. 10 to 13, raw water for hot water (hot water or mixed hot water) that has flowed into the secondary non-purified raw water flow channel 30 c from the upstream side of the secondary non-purified raw water flow channel 30 c, Toward the downstream side, the non-purified raw water flow path 38a in the inner steel pipe member 38, the non-purified raw water flow path 62a in the inner hose joint 62, the non-purified raw water flow path 72a in the inner hose 72, and the inner joint The non-purified raw water flow path 90a of the member 90 flows from the non-purified raw water flow path 102 in the water discharge head section 8 to the straight water discharge flow path 106, and finally, unpurified raw water (hot water or hot water) Mixed hot water) is discharged from the water discharge part 8a of the water discharge head part 8. It is bets water discharge.

つぎに、図１４の（ｂ）に示すように、原水シャワー吐水モードとは、吐水ヘッド８の切替スイッチ８ｂをシャワー吐水モードに設定した状態で、操作ハンドル６を水吐水モードの操作位置Ｐ１（図６の（ａ）参照）、湯吐水モードの操作位置Ｐ２（図７の（ａ）参照）、又は湯水混合吐水モードの操作位置Ｐ３（図７の（ａ）参照）のいずれかに設定したときの吐水モードを意味する。
この原水シャワー吐水モードに設定した場合においては、流路形成部材３０の二次側非浄水用原水流路３０ｃの上流側から二次側非浄水用原水流路３０ｃ内に流入した非浄水用の原水（水、湯又は混合湯水）が、図１０〜図１３に示すように、下流側に向って、内側鋼管部材３８内の非浄水用原水流路３８ａ、インナーホース継手６２内の非浄水用原水流路６２ａ、インナーホース７２内の非浄水用原水流路７２ａ、及び内側継手部材９０の非浄水用原水流路９０ａを経て吐水ヘッド部８内の非浄水用原水流路１０２を流れる点については、上述した原水ストレート吐水モードの場合と共通するが、吐水ヘッド８の切替スイッチ８ｂの切替弁（図示せず）がストレート吐水用の吐水流路１０６を閉鎖すると共にシャワー吐水用の吐水流路１０８を開放することにより、浄水されていな原水（水、湯又は混合湯水）がシャワー吐水用の吐水流路１０８を流れ、最終的には、吐水ヘッド部８の吐水部８ａからシャワー吐水される。 Next, as shown in FIG. 14 (b), the raw water shower water discharge mode is a state in which the operation switch 6 is set to the operation position P1 (in the water discharge mode) with the changeover switch 8b of the water discharge head 8 set to the shower water discharge mode. 6) (see FIG. 6A), the operation position P2 in the hot water discharge mode (see FIG. 7A), or the operation position P3 in the hot water mixed discharge mode (see FIG. 7A). It means the water discharge mode.
When this raw water shower discharge mode is set, the non-purified water flowing into the secondary non-purified raw water flow path 30c from the upstream side of the secondary non-purified raw water flow path 30c of the flow path forming member 30. As shown in FIGS. 10 to 13, the raw water (water, hot water or mixed hot water) is used for non-purified water in the non-purified raw water flow path 38 a in the inner steel pipe member 38 and the inner hose joint 62 toward the downstream side. About the point which flows through the raw water flow path 102a in the water discharging head part 8 through the raw water flow path 62a, the raw water flow path 72a in the inner hose 72, and the non-purified raw water flow path 90a in the inner joint member 90 Is the same as in the case of the raw water straight water discharge mode described above, but a switching valve (not shown) of the changeover switch 8b of the water discharge head 8 closes the water discharge channel 106 for straight water discharge and a water discharge channel for shower water discharge. 10 By opening the raw water not been purified water (water, hot water or mixed hot water) flows through the water discharge passage 108 of the shower water discharge is ultimately shower water discharge from the water discharge portion 8a of the water discharge head 8.

つぎに、図１４の（ｃ）に示すように、浄水ストレート吐水モードとは、吐水ヘッド８の切替スイッチ８ｂをストレート吐水モード又はシャワー吐水モードのいずれかに設定した状態で、操作ハンドル６を浄水吐水モードの操作位置Ｐ４（図８の（ａ）参照）に設定したときの吐水モードを意味する。
この浄水ストレート吐水モードに設定した場合においては、図３、図４、図８の（ａ）及び（ｂ）、並びに図１０に示すように、操作ハンドル６を浄水吐水モードに設定すると、給水管４から供給される非浄水用の原水（浄水化される前の原水）が、流路形成部材３０の一次側水流路３０ｂから固定弁体２２の一次側水流路２２ｂを通過し、可動弁体２４の一次側流路２４ａ及び二次側流路２４ｂから固定弁体２２の二次側浄水用原水流路２２ｄを経て流路形成部材３０の二次側浄水用原水流路３０ｄ及び接続流路４８を通過する。 Next, as shown in FIG. 14 (c), the purified water straight water discharge mode means that the operation handle 6 is cleaned with the changeover switch 8b of the water discharge head 8 set to either the straight water discharge mode or the shower water discharge mode. It means the water discharge mode when set to the operation position P4 (see (a) of FIG. 8) of the water discharge mode.
In the case where the water purification straight water discharge mode is set, as shown in FIGS. 3, 4, 8 (a) and (b) and FIG. 10, when the operation handle 6 is set to the water purification water discharge mode, The raw water for non-purification supplied from 4 (raw water before being purified) passes from the primary side water flow path 30b of the flow path forming member 30 to the primary side water flow path 22b of the fixed valve body 22, and the movable valve body 24 from the primary side flow path 24a and the secondary side flow path 24b through the secondary side water purification raw water flow path 22d of the fixed valve body 22 and the secondary side raw water purification water path 30d and the connection flow path of the flow path forming member 30 Pass 48.

そして、この浄水用の原水（浄水化される前の原水）は、図１０〜図１３に示すように、下流側に向って、内側鋼管部材３８の外周側の浄水用原水流路３６ａ、中継パイプ５８の外周側の浄水用原水流路５８ａ、インナーホース継手６２の外周側の浄水用原水流路７０ｃ、インナーホース７２の外周側の浄水用原水流路７４ａ、及び内側継手部材９０の外周側の浄水用原水流路９０ｂを経て吐水ヘッド部８の内側ケーシング部材９８内の浄水カートリッジ１００を通過することにより浄水化される。さらに、この浄水は、吐水ヘッド部８内の浄水流路１１０を通過し、ストレート吐水用の吐水流路１０６に流れ込み、最終的には、吐水ヘッド部８の吐水部８ａからストレート吐水される。
なお、浄水ストレート吐水モードに設定した場合においては、浄水流路１１０が、切替スイッチ８ｂの操作位置にかかわらず、吐水部８ａのストレート吐水用の吐水流路１０６と常時連通しているため、吐水ヘッド８の切替スイッチ８ｂをシャワー吐水モードに設定したとしても、シャワー状の浄水吐水は行われずに、ストレート状の浄水吐水のみが行われる。 And, as shown in FIGS. 10 to 13, this raw water for water purification (raw water before being purified) is directed to the downstream side, as shown in FIGS. 10 to 13. The water purification raw water flow path 58 a on the outer peripheral side of the pipe 58, the water purification raw water flow path 70 c on the outer peripheral side of the inner hose joint 62, the raw water flow path 74 a for water purification on the outer peripheral side of the inner hose 72, and the outer peripheral side of the inner joint member 90 The water is purified by passing through the water purification cartridge 100 in the inner casing member 98 of the water discharge head portion 8 through the raw water flow path 90b. Further, the purified water passes through the purified water flow path 110 in the discharged water head section 8 and flows into the discharged water flow path 106 for straight discharged water, and finally is discharged straight from the discharged water section 8 a of the discharged water head section 8.
In addition, in the case of setting to the purified water straight water discharge mode, the water purification channel 110 is always in communication with the water discharge channel 106 for straight water discharge of the water discharge part 8a regardless of the operation position of the changeover switch 8b. Even if the changeover switch 8b of the head 8 is set to the shower water discharge mode, the shower-like water discharge is not performed, and only the straight water discharge is performed.

上述した本発明の一実施形態による水栓装置１によれば、インナーホース７２の内周側の非浄水用原水流路７２ａ内を非浄水用の原水（水、湯、又は混合湯水）が流れる際には、弾性材料で形成されたインナーホース７２の区間（弾性区間）が非浄水用原水流路７２ａ内の水圧により半径方向外側に拡張するように弾性変形し、インナーホース７２の非浄水用原水流路７２ａの流路断面積が増大し、インナーホース７２の外周面とアウターホース７４の内周面との間の浄水用原水流路７４ａの流路断面積が減少する。
一方、インナーホース７２の外周側の浄水用原水流路７４ａ内を浄水用の原水（浄水化される前の原水）が流れる際には、インナーホース７２の区間（弾性区間）がその外周側の浄水用原水流路７４ａ内の水圧によりインナーホース７２が半径方向内側に押圧されるように弾性変形し、インナーホース７２内の非浄水用原水流路７２ａの流路断面積が減少し、インナーホース７２の外周側の浄水用原水流路７４ａの流路断面積が増大する。これにより、ホース部材１６よりも上流側にあるバルブカートリッジ２８と流路形成部材３０とにより選択的に切り替えた吐水について、インナーホース７２の内周側の非浄水用原水流路７２ａ内を流れる非浄水用の原水（水、湯、又は混合湯水）、又はインナーホース７２の外周側の浄水用原水流路７４ａを流れる浄水用の原水（浄水化される前の原水）として選択的に流すことができる。したがって、インナーホース７２の内周側の非浄水用原水流路７２ａ内を流れる非浄水用の原水（水、湯、又は混合湯水）と、インナーホース７２の外周側の浄水用原水流路７４ａを流れる浄水用の原水（浄水化される前の原水）とを互いに混合させることなく、それぞれの吐水流路の断面積を増大させることができ、ホース部材１６の下流側の吐水ヘッド部８から吐水する際の流量を増大させることができる。 According to the faucet device 1 according to the embodiment of the present invention described above, the raw water for non-purified water (water, hot water, or mixed hot water) flows through the non-purified raw water flow path 72 a on the inner peripheral side of the inner hose 72. In this case, a section (elastic section) of the inner hose 72 formed of an elastic material is elastically deformed so as to expand radially outward by the water pressure in the non-purified raw water flow path 72a, and the inner hose 72 is used for non-purified water. The flow passage cross-sectional area of the raw water flow passage 72a increases, and the flow passage cross-sectional area of the purified water raw water flow passage 74a between the outer peripheral surface of the inner hose 72 and the inner peripheral surface of the outer hose 74 decreases.
On the other hand, when the raw water for water purification (raw water before being purified) flows through the raw water flow path 74a on the outer peripheral side of the inner hose 72, the section (elastic section) of the inner hose 72 is on the outer peripheral side. The inner hose 72 is elastically deformed so as to be pressed radially inward by the water pressure in the raw water flow path 74 a for water purification, and the cross-sectional area of the non-purified raw water flow path 72 a in the inner hose 72 is reduced. The flow path cross-sectional area of the raw water flow path 74a for water purification on the outer peripheral side of 72 increases. As a result, the water discharged selectively by the valve cartridge 28 and the flow path forming member 30 on the upstream side of the hose member 16 is not flowed in the non-purified raw water flow path 72 a on the inner peripheral side of the inner hose 72. Flowing selectively as raw water for water purification (water, hot water, or mixed hot water) or raw water for water purification (raw water before being purified) flowing through the raw water flow path 74a for water purification on the outer peripheral side of the inner hose 72 it can. Therefore, non-purified raw water (water, hot water, or mixed hot water) flowing in the non-purified raw water flow path 72 a on the inner peripheral side of the inner hose 72 and the raw water flow path 74 a for purified water on the outer peripheral side of the inner hose 72 are provided. The cross-sectional area of each water discharge channel can be increased without mixing the raw water for water purification (raw water before being purified) with each other, and water is discharged from the water discharge head portion 8 on the downstream side of the hose member 16. The flow rate when doing so can be increased.

また、本実施形態による水栓装置１によれば、鋼管部材１８の内側鋼管部材３８及び外側鋼管部材３６と、ホース部材１６のインナーホース７２及びアウターホース７４が、バルブカートリッジ２８の下側（下流側）の流路形成部材３０と吐水ヘッド部８との間に接続されているため、シングルレバー式の混合水栓装置本体１０の操作ハンドル６による吐水モードを水吐水モード、湯吐水モード、湯水混合吐水モード、又は浄水吐水モードのいずれかに選択的に切り替えた吐水操作を行うだけで、バルブカートリッジ２８から鋼管部材１８及びホース部材１６を経て吐水ヘッド部８へ流れる非浄水用の原水（水、湯、又は混合湯水）と浄水用の原水（浄水化される前の原水）のそれぞれが流れる流路を鋼管部材１８の上流側で容易に選択的に切り替えることができる。また、吐水ヘッド部８とこれに接続されているホース部材１６をシングルレバー式の混合水栓装置本体１０から取り外し、引き出した状態で使用することもできるため、使い勝手もよい。   Further, according to the faucet device 1 according to the present embodiment, the inner steel pipe member 38 and the outer steel pipe member 36 of the steel pipe member 18, and the inner hose 72 and the outer hose 74 of the hose member 16 are disposed on the lower side (downstream) of the valve cartridge 28. Side) flow path forming member 30 and the water discharge head portion 8 are connected to each other, so that the water discharge mode by the operation handle 6 of the single lever type mixing faucet body 10 is the water discharge mode, the hot water discharge mode, and the hot water. Non-purified raw water (water) that flows from the valve cartridge 28 to the water discharge head unit 8 through the steel pipe member 18 and the hose member 16 only by performing a water discharge operation selectively switched to either the mixed water discharge mode or the purified water discharge mode. , Hot water, or mixed hot water) and raw water for water purification (raw water before being purified) are easily and selectively selected on the upstream side of the steel pipe member 18. Ri can be replaced. Moreover, since the water discharge head part 8 and the hose member 16 connected to the water discharge head part 8 can be detached from the single lever type mixing faucet body 10 and used in the pulled-out state, it is easy to use.

さらに、本実施形態による水栓装置１によれば、ホース部材１６のアウターホース７４の外周面が補強層により覆われているため、アウターホース７４の内部の非浄水用原水流路７２ａ内や浄水用原水流路７４ａ内で大きな水圧が作用したとしても、アウターホース７４内の流路断面が半径方向外側に所定以上に拡張することを防ぐことができ、アウターホース７４が破裂する等の損傷を防ぐことができる。   Furthermore, according to the faucet device 1 according to the present embodiment, since the outer peripheral surface of the outer hose 74 of the hose member 16 is covered with the reinforcing layer, the inside of the non-purified raw water flow path 72a inside the outer hose 74 and the purified water Even if a large water pressure acts in the raw water flow path 74a, it is possible to prevent the cross section of the flow path in the outer hose 74 from expanding beyond the radial direction to a predetermined extent or more, and damage such as the outer hose 74 bursting. Can be prevented.

また、本実施形態による水栓装置１によれば、混合水栓装置本体１０に内蔵された流路形成部材３０が、内側鋼管部材３８の上端部（上流側端部）が接続される内側鋼管部材接続部４０と、外側鋼管部材３６の上端部（上流側端部）が接続される外側鋼管部材接続部４４とを備えていることにより、混合水栓装置本体１０と鋼管部材１８を直接的に接続することができる簡易な構造であるため、施工性を向上させることができる。   Further, according to the faucet device 1 according to the present embodiment, the flow path forming member 30 built in the mixed faucet device body 10 is connected to the inner steel pipe to which the upper end portion (upstream end portion) of the inner steel pipe member 38 is connected.

Since it is a simple structure that can be connected to the cable, the workability can be improved.

さらに、本実施形態による水栓装置１によれば、外側鋼管部材接続部４４よりも上流側に位置する流路形成部材３０の二次側非浄水用原水流路３０ｃと二次側浄水用原水流路３０ｄは、それぞれの流路断面の中心軸線Ａ２，Ａ３（図１０参照）が互いに偏心していることにより、流路形成部材３０の外側鋼管部材接続部４４よりも上流側で二次側非浄水用原水流路３０ｃと二次側浄水用原水流路３０ｄとが互いに別々の流路として形成されている。したがって、これら別々の二次側非浄水用原水流路３０ｃ及び二次側浄水用原水流路３０ｄのそれぞれと、流路形成部材３０の上流側のバルブカートリッジ２８の固定弁体２２に形成される二次側非浄水用原水流２２ｃ及び二次側浄水用原水流路２２ｄのそれぞれとを容易に接続することができる。   Furthermore, according to the faucet device 1 according to the present embodiment, the secondary-side non-purified raw water flow path 30c and the secondary-side water purification raw material of the flow path forming member 30 located on the upstream side of the outer steel pipe member connecting portion 44. The water flow path 30d has a non-secondary side on the upstream side of the outer steel pipe member connecting portion 44 of the flow path forming member 30 because the central axes A2 and A3 (see FIG. 10) of the cross sections of the flow paths are eccentric to each other. The purified water raw water flow path 30c and the secondary side purified water raw water flow path 30d are formed as separate flow paths.
