WATER SECTION APPLIANCE
PROBLEM TO BE SOLVED: To provide a water section appliance capable of suppressing back flow of modified water more surely.SOLUTION: A water section appliance comprises a modified water generator for modifying the nature of water and generating modified water, a water discharge part that is installed on the downstream side of the modified water generator and that discharges modified water, and a back-flow prevention device installed on the upstream side of the modified water generator. The back-flow prevention device comprises: a first flow path part; a second flow path part installed on the downstream side of the first flow path part; an intermediate chamber installed between the first flow path part and the second flow path part; a first non-return valve installed between the first flow path part and the intermediate chamber; a second non-return valve installed between the second flow path part and the intermediate chamber; a discharge port for discharging water in the intermediate chamber; a relief valve for opening/closing the discharge port; and a drive part for opening the discharge port by operating the relief valve when a differential pressure is generated between the first flow path part and the intermediate chamber.SELECTED DRAWING: Figure 1
【課題】より確実に改質水の逆流を抑制できる水周り機器を提供する。【解決手段】水の性質を改質して改質水を生成する改質水生成器と、改質水生成器よりも下流側に設けられ、改質水を吐水する吐水部と、改質水生成器よりも上流側に設けられた逆流防止装置と、を備え、逆流防止装置は、第１流路部と、第１流路部の下流に設けられた第２流路部と、第１流路部と第２流路部との間に設けられた中間室と、第１流路部と中間室との間に設けられた第１逆止弁と、第２流路部と中間室との間に設けられた第２逆止弁と、中間室内の水を排出する排出口と、排出口を開閉する逃がし弁と、第１流路部と中間室との間に差圧が発生した際に、逃し弁を動作させて排出口を開放する駆動部と、を有することを特徴とする水周り機器である。【選択図】図１
