次に、上記のように構成された実施例１の混合水栓１の作用について説明する。
この混合水栓１は、熱湯を吐出する場合、回動式ハンドル６０を操作する。これにより、給湯部１０から供給された熱湯が、接続管１４を介して、本体部３０のハウジング３２の吐出用熱湯流入口３２Ｅから流入する。流入した熱湯は、吐出用熱湯流通路ＨＤ、吐出管側熱湯流通路ＨＰを流通して、熱湯吐出口４３Ｄから吐出される。一方、この混合水栓１は、混合湯又は水を吐出する場合、レバー式ハンドル５０を操作する。このレバー式ハンドル５０によって混合弁３１が操作される。混合弁３１には、混合用熱湯流通路ＨＭ、及び水流通路Ｃが接続されており、これらを流通して供給された熱湯及び水を混合した混合湯又は水を流出する。混合弁３１から流出した混合湯又は水は、湯水流通路Ｍ、及び吐出管側湯水流通路ＭＰを経て湯水吐出口４５Ａから吐出される。 Next, the operation of the mixing faucet 1 of the first embodiment configured as described above will be described.
The mixing faucet 1 operates a rotary handle 60 when discharging hot water. As a result, the hot water supplied from the hot water supply unit 10 flows in from the discharge hot water inflow port 32E of the housing 32 of the main body unit 30 via the connection pipe 14. The inflowing hot water flows through the hot water flow passage HD for discharge and the hot water flow passage HP on the discharge pipe side, and is discharged from the hot water discharge port 43D. On the other hand, this mixing faucet 1 operates the lever type handle 50 when discharging the mixed hot water or water. The mixing valve 31 is operated by the lever type handle 50. A hot water flow passage HM for mixing and a water flow passage C are connected to the mixing valve 31, and the mixed hot water or water mixed with the hot water and water supplied through these is discharged. The mixed hot water or water flowing out of the mixing valve 31 is discharged from the hot water discharge port 45A via the hot water flow passage M and the hot water flow passage MP on the discharge pipe side.

以上のように、実施例１の混合水栓１は、熱湯が流通する熱湯流通路としての混合用熱湯流通路ＨＭ及び吐出用熱湯流通路ＨＤと、水が流通する水流通路Ｃと、混合用熱湯流通路ＨＭ及び吐出用熱湯流通路ＨＤから水流通路Ｃへの熱伝導を抑制する伝熱抑制部としての樹脂製の本体部３０とを備えている。 As described above, the mixing faucet 1 of the first embodiment is used for mixing the hot water flow passage HM for mixing and the hot water flow passage HD for discharge as the hot water flow passage through which hot water flows, and the water flow passage C through which water flows. It is provided with a resin main body portion 30 as a heat transfer suppressing portion that suppresses heat conduction from the hot water flow passage HM and the hot water flow passage HD for discharge to the water flow passage C.

混合水栓１は、伝熱抑制部としての本体部３０を備えていることにより、混合用熱湯流通路ＨＭ及び吐出用熱湯流通路ＨＤから水流通路Ｃへの熱伝導が抑制される。このため、混合水栓１は、混合用熱湯流通路ＨＭ及び吐出用熱湯流通路ＨＤ内の熱湯の熱が水流通路Ｃ内の水に伝導して水が加温されてしまうのを抑制することができる。 Since the mixing faucet 1 includes a main body portion 30 as a heat transfer suppressing portion, heat conduction from the mixing hot water flow passage HM and the discharge hot water flow passage HD to the water flow passage C is suppressed. Therefore, the mixing faucet 1 suppresses the heat of the hot water in the hot water flow passage HM for mixing and the hot water flow passage HD for discharge from being conducted to the water in the water flow passage C to heat the water. Can be done.

したがって、実施例１の混合水栓１は、混合水栓１は、熱湯からの熱伝導を好適に抑制することができる。 Therefore, in the mixing faucet 1 of the first embodiment, the mixing faucet 1 can suitably suppress the heat conduction from the boiling water.

また、混合水栓１は、熱湯と水とを混合した混合湯又は水が流通する湯水流通路Ｍを備えている。そして、伝熱抑制部としての樹脂製の本体部３０は、混合用熱湯流通路ＨＭ及び吐出用熱湯流通路ＨＤから湯水流通路Ｍへの熱伝導を抑制する。このように、伝熱抑制部としての本体部３０は、混合用熱湯流通路ＨＭ及び吐出用熱湯流通路ＨＤから湯水流通路Ｍへの熱伝導を抑制するので、混合用熱湯流通路ＨＭ及び吐出用熱湯流通路ＨＤ内の熱湯の熱が湯水流通路Ｍ内の混合湯又は水に伝導して加温されてしまうのを抑制することができる。 Further, the mixing faucet 1 includes a mixed hot water mixed with hot water and water, or a hot water flow passage M through which water flows. The resin main body 30 as the heat transfer suppressing portion suppresses heat conduction from the hot water flow passage HM for mixing and the hot water flow passage HD for discharge to the hot water flow passage M. In this way, the main body 30 as the heat transfer suppressing portion suppresses heat conduction from the hot water flow passage HM for mixing and the hot water flow passage HD for discharge to the hot water flow passage M, so that the hot water flow passage HM for mixing and the discharge are suppressed. It is possible to prevent the heat of the hot water in the hot water flow passage HD from being conducted to the mixed hot water or water in the hot water flow passage M and being heated.

また、混合水栓１は、内部に混合用熱湯流通路ＨＭ、吐出用熱湯流通路ＨＤ、水流通路Ｃ、及び湯水流通路Ｍが形成されるとともに、混合用熱湯流通路ＨＭからの熱湯及び水流通路Ｃからの水を混合して湯水流通路Ｍに流出する混合弁３１を有した樹脂製の本体部３０を備えており、伝熱抑制部はこの本体部３０を有して構成されている。このように、金属と比較して熱伝導率の低い樹脂製の本体部としたことにより、本体部を経由した熱湯流通路から湯水流通路への熱伝導を抑制することができる。 Further, the mixing faucet 1 is formed with a hot water flow passage HM for mixing, a hot water flow passage HD for discharge, a water flow passage C, and a hot water flow passage M inside, and hot water and water flow from the hot water flow passage HM for mixing. A resin main body portion 30 having a mixing valve 31 that mixes water from the passage C and flows out to the hot water flow passage M is provided, and the heat transfer suppressing portion is configured to have the main body portion 30. .. As described above, by forming the main body portion made of resin having a lower thermal conductivity than that of metal, it is possible to suppress heat conduction from the hot water flow passage to the hot water flow passage via the main body portion.

また、混合水栓１は、本体部３０に熱湯を供給する給湯部１０と、本体部３０に水を供給する給水部２０と、が設けられており、本体部３０は、給湯部１０と給水部２０との間に配置されている。そして、伝熱抑制部としての本体部３０は、給湯部１０から給水部２０への熱伝導を抑制している。このように、伝熱抑制部としての本体部３０は、本体部３０を経由した給湯部１０から給水部２０への熱伝導を抑制するので、給湯部１０の熱湯の熱が給水部２０の水に伝導して加温されてしまうのを抑制することができる。 Further, the mixing faucet 1 is provided with a hot water supply unit 10 for supplying hot water to the main body 30 and a water supply unit 20 for supplying water to the main body 30, and the main body 30 is provided with the hot water supply unit 10 and water supply. It is arranged between the unit 20 and the unit 20. The main body 30 as a heat transfer suppressing section suppresses heat conduction from the hot water supply section 10 to the water supply section 20. In this way, the main body 30 as the heat transfer suppressing unit suppresses heat conduction from the hot water supply unit 10 to the water supply unit 20 via the main body 30, so that the heat of the hot water of the hot water supply unit 10 is the water of the water supply unit 20. It is possible to prevent the heat from being conducted and heated.

また、混合水栓１は、内部に熱湯流通路としての吐出管側熱湯流通路ＨＰ及び湯水流通路としての吐出管側湯水流通路ＭＰが形成されるとともに、上流側の端部が本体部３０に接続されており、下流側の端部に熱湯流通路を形成する熱湯流通管部材４２及び湯水流通路を形成する湯水流通管部材４４が夫々接続された樹脂製の連結部４１が設けられており、伝熱抑制部は、この連結部４１を有して構成されている。このように、金属と比較して熱伝導率の低い樹脂製の連結部としたことにより、連結部を経由した熱湯流通路から湯水流通路への熱伝導を抑制することができる。 Further, in the mixing faucet 1, a discharge pipe side hot water flow passage HP as a hot water flow passage and a discharge pipe side hot water flow passage MP as a hot water flow passage are formed inside, and the upstream end is the main body 30. A resin connecting portion 41 is provided at the downstream end to which the hot water flow pipe member 42 forming the hot water flow passage and the hot water flow pipe member 44 forming the hot water flow passage are connected to each other. The heat transfer suppressing portion is configured to have the connecting portion 41. As described above, by forming the connecting portion made of resin having a lower thermal conductivity than that of metal, it is possible to suppress the heat conduction from the hot water flow passage to the hot water flow passage via the connecting portion.

また、混合水栓１は、熱湯流通路としての吐出管側熱湯流通路ＨＰを形成する熱湯流通管部材４２及び湯水流通路としての吐出管側湯水流通路ＭＰを形成する湯水流通管部材４４が内部に配された吐出管４０が設けられている。そして、伝熱抑制部は、熱湯流通管部材４２から湯水流通管部材４４への熱伝導を抑制する。このように、伝熱抑制部は、本体部３０を経由した熱湯流通管部材から湯水流通管部材への熱伝導を抑制するので、熱湯流通管部材の熱湯の熱が湯水流通管部材の混合湯又は水に伝導して加温されてしまうのを抑制することができる。これにより、１つの吐出管４０内を流通する熱湯や混合湯又は水の間の放熱や吸熱が抑制されるので、熱湯及び混合湯又は水を好適に吐出することができる。その結果、熱湯と、混合湯又は水とを吐出する吐出管を別々に設けた場合と比較して小型化することができ、省スペース化を図ることができる。 Further, in the mixing faucet 1, the hot water flow pipe member 42 forming the hot water flow passage HP on the discharge pipe side as the hot water flow passage and the hot water flow pipe member 44 forming the hot water flow passage MP on the discharge pipe side as the hot water flow passage A discharge pipe 40 arranged inside is provided. Then, the heat transfer suppressing unit suppresses heat conduction from the hot water flow pipe member 42 to the hot water flow pipe member 44. In this way, the heat transfer suppressing section suppresses heat conduction from the hot water flow tube member to the hot water flow tube member via the main body 30, so that the heat of the hot water of the hot water flow tube member is the mixed hot water of the hot water flow tube member. Alternatively, it can be prevented from being heated by being conducted by water. As a result, heat dissipation and heat absorption between the hot water, the mixed hot water, or the water flowing in one discharge pipe 40 are suppressed, so that the hot water, the mixed hot water, or the water can be suitably discharged. As a result, the size can be reduced as compared with the case where the hot water and the discharge pipe for discharging the mixed hot water or water are separately provided, and the space can be saved.

また、混合水栓１は、伝熱抑制部としての樹脂製の本体部３０を備えたので、熱湯流通路としての混合用熱湯流通路ＨＭ及び吐出用熱湯流通路ＨＤ内の熱湯からの放熱が抑制され、熱湯の温度低下を抑制することができる。 Further, since the mixing faucet 1 is provided with a resin main body portion 30 as a heat transfer suppressing portion, heat can be dissipated from the hot water in the hot water flow passage HM for mixing and the hot water flow passage HD for discharge as the hot water flow passage. It is suppressed and the temperature drop of boiling water can be suppressed.
