【考案の詳細な説明】 〔産業上の利用分野〕 本考案は、水栓の吐水口にシャワーホースを接続するた
めのシャワーホース用の継手に関するものである。[Detailed Description of the Invention] [Industrial application] The present invention relates to a shower hose joint for connecting a shower hose to a water outlet of a faucet.
例えば、シャワー側とスパウト側とに切り換え自在に構
成された水栓において、前記スパウト側への吐水時にシ
ャワーヘッドから空気が吸引されることによる騒音防止
や、水栓上流側での負圧現象による水栓側へのシャワー
流路内の水の逆流防止のために、シャワー流路の水栓近
傍に逆止弁が設けられている。For example, in a faucet configured to be switchable between a shower side and a spout side, noise prevention due to air being sucked from a shower head at the time of water discharge to the spout side, and a negative pressure phenomenon on the upstream side of the faucet A check valve is provided near the faucet of the shower channel to prevent backflow of water in the shower channel toward the faucet side.
あるいは、シャワー専用の水栓においても、負圧現象に
よる逆流を防止する上で、シャワー流路の水栓近傍に逆
止弁が設けられている。Alternatively, even in a faucet dedicated to a shower, a check valve is provided near the faucet in the shower channel in order to prevent backflow due to a negative pressure phenomenon.
一方、寒冷地等では、シャワー流路内の滞留水の凍結防
止のためにシャワー流路内の滞留水を排水する必要があ
