Description

本発明は、湯水混合水栓に係り、特に、給湯源から供給される湯と給水源から供給される水とを混合した湯水混合水を吐止水する湯水混合水栓に関する。 The present invention relates to a hot and cold water mixing faucet, and more particularly to a hot and cold water mixing faucet for discharging hot and cold water mixed water obtained by mixing hot water supplied from a hot water supply source and water supplied from a water supply source.

従来から、給湯源から供給される湯と給水源から供給される水とを混合した湯水を吐止水する湯水混合水栓として、例えば、特許文献１に記載されているように、湯水混合弁と流量調整弁とが水栓本体内に直接的に挿入されて収納されたものが知られている。また、湯水混合弁と流量調整弁とが収納された状態の水栓本体内の壁面等には、湯や水の複雑な流路が確保されている。 Conventionally, as a hot and cold water mixing faucet for discharging hot and cold water that mixes hot water supplied from a hot water supply source and water supplied from a water supply source, for example, as described in Patent Document 1, a hot and cold water mixing valve It is known that the and the flow rate adjusting valve are directly inserted and housed in the faucet body. Further, a complicated flow path for hot water or water is secured on the wall surface or the like in the faucet body in a state where the hot water mixing valve and the flow rate adjusting valve are accommodated.

しかしながら、上述した従来の湯水混合水栓においては、一般的には、水栓本体が鋳型成形品であることから、製造時には、水栓本体に対して湯や水の複雑な内部流路を形成するための特殊な鋳型を用いた鋳型成形や、水栓本体の内壁等に特別な機械加工等が必要となるため、製造効率が低下するという問題がある。
また、水栓本体に湯や水の複雑な流路を確保することにより、水栓本体の外形寸法（例えば、水栓本体の外径等）が大きくなることによるデザイン性の低下や、水栓本体の重量増による製造コストが増大するという問題がある。
さらに、近年では、国内外における様々な設置状況に応じて要求される湯水混合水栓の仕様が異なる場合がある。例えば、設置状況によっては、通常の仕様よりも湯水混合水栓の長手方向の外形寸法が長尺な仕様のものを使用する場合や、湯水混合水栓の湯流入口と水流入口との軸心間距離（湯水混合水栓の湯流入口の中心軸線と水流入口の中心軸線との距離）がより長い仕様のものを使用する場合等があり、これらの場合、水栓本体の湯流入口及び水流入口のそれぞれから水栓本体の排出口に至るまでの内部流路の経路が複雑になり、経路長さも長くなるため、このような内部流路を確保するための製造コストもさらに増大するという問題がある。
したがって、水栓本体の内部流路をいかに簡単な経路にするかが要請された課題となっている。
また、上述した従来の湯水混合水栓においては、水栓本体が鋳型成形品であるため、特に、水栓本体における湯側領域の表面や混合湯水の排出口付近の表面において、内部の通湯温度の熱が伝わり、使用者が表面に触れることができない程度に熱くなる場合もあるため、水栓本体のデザイン性を高めつつ、水栓本体の表面が熱くならないように通水させるための通水路等の内部流路をいかに確保するかについても要請された課題となっている。 However, in the above-mentioned conventional hot and cold water mixing faucet, since the faucet body is generally a molded product, a complicated internal flow path of hot water or water is formed in the faucet body at the time of manufacturing. There is a problem in that the manufacturing efficiency is lowered because it is necessary to perform mold forming using a special mold for this purpose and special machining for the inner wall of the faucet body.
In addition, by ensuring a complicated flow path for hot water or water in the faucet body, the external dimension of the faucet body (for example, the outer diameter of the faucet body) becomes large and the designability is deteriorated. There is a problem that the manufacturing cost increases due to the increase in the weight of the main body.
Further, in recent years, the specifications of the hot and cold water mixing faucet required may vary depending on various installation conditions in Japan and overseas. For example, depending on the installation situation, when using a specification with a longer external dimension in the longitudinal direction of the hot and cold water mixing faucet than the normal specifications, or when using the axial center between the hot water inlet and the hot water inlet of the hot and cold water mixing faucet There may be cases where a product with a longer distance (the distance between the center axis of the hot water inlet of the hot and cold water mixing tap and the center axis of the hot water inlet) is used, and in these cases, the hot water inlet and Since the path of the internal flow path from each of the water inlets to the outlet of the faucet body becomes complicated and the path length becomes long, the manufacturing cost for securing such internal flow path further increases. There's a problem.
Therefore, how to make the internal flow path of the faucet body a simple route has been a demanded issue.
Further, in the above-described conventional hot and cold water mixing faucet, since the water faucet body is a molded product, the internal hot water flow is generated especially on the surface of the hot water side region of the faucet body or the surface near the outlet of the mixed hot water. Since the heat of temperature may be transmitted and become hot enough for the user not to touch the surface, it is necessary to improve the design of the faucet body while allowing water to pass through so that the surface of the faucet body does not get hot. How to secure internal flow channels such as water channels has also become a challenge.

そこで、本発明は、上述した従来技術の問題や要請された課題を解決するためになされたものであり、水栓本体の内部流路を簡単な経路にすることにより水栓本体の外形寸法を小型化することができると共に、デザイン性を高めることができる湯水混合水栓を提供することを目的としている。 Therefore, the present invention has been made in order to solve the above-mentioned problems of the prior art and the requested problems, and the external dimensions of the faucet body can be reduced by making the internal flow path of the faucet body a simple path. It is an object of the present invention to provide a hot and cold water mixing faucet that can be downsized and can be improved in design.

このように構成された本発明においては、流量調整弁ユニットが、その一端が水栓本体の他端側から流量調整弁ハウジングを介して挿入された状態で筒状部内に保持される共に、湯水混合弁ユニット側から流量調整弁ユニット内に流入した湯水混合水を流出させる流出口と、水栓本体の上記筒状部内に設けられた円筒状の弁座部材と、この弁座部材内に同軸に回転可能に設けられた円筒状の弁部材と、を備えており、流量調整弁ハウジングの一端側が水栓本体の筒状部に水密に接続され且つ流量調整弁ハウジングの他端側が水栓本体の他端部に水密に接続された状態で、円筒状の弁座部材及び円筒状の弁部材の他端側に配置され、流量調整弁ユニットの流出口と水栓本体の排出口とが互いに直接的に重なり合うように流量調整弁ハウジングが水栓本体の他端と筒状部の他端との間に配置されているスペーサであることにより、流量調整弁ユニットの流出口と水栓本体の排出口との間の流路を最短に形成することができる。
したがって、水栓本体の内部流路を簡単な経路にすることができ、水栓本体の外形寸法（例えば、水栓本体の外径等）を小型化することができるため、湯水混合水栓のデザイン性を高めることができる。
また、流量調整弁ハウジングにより、水栓本体と流量調整弁ハウジングとの間における水栓本体の排出口の近傍にも通水路が形成されるため、使用者が水栓本体の表面に触れたとしても熱くない湯水混合水栓とすることができる。 In order to solve the above-mentioned problems, the present invention is a hot and cold water mixed faucet for discharging hot and cold water mixed water obtained by mixing hot water supplied from a hot water supply source and water supplied from a water supply source.
