HOT-WATER/WATER MIXING DEVICE
To provide a hot-water/water mixing device capable of stable temperature control.SOLUTION: A hot-water/water mixing device 10 comprises: a water supply pipe 1C; a hot-water supply pipe 1H; a mixing pipe 1M; flow rate control valves 4C, 4H; temperature sensors 3C, 3H; flow rate sensors 5C, 5H; a setting part 70; and a control part 80. The control part 80 compares a water side opening degree VPc indicating an opening degree of a water supply path opened by the flow rate control valve 4C, and a hot-water side opening degree VPh indicating an opening degree of a hot-water supply path opened by the flow rate control valve 4H, calculates and updates target flow rates QC1, QH1 of the flow rate control valves 4C, 4H in either the water supply path or the hot-water supply path having a smaller opening degree based on flow rates QC, QH acquired by the flow rate sensors 5C, 5H of either the water supply path or the hot-water supply path having a larger opening degree of the water side opening degree VPc and the hot-water side opening degree VPh, and controls the flow rate control valves 4C, 4H having a smaller one of the opening degrees VPc, VPh with the target flow rates QC1, QH1 of the flow rate control valves 4C, 4H having a smaller one of the updated opening degrees VPc, VPh, as a reference.SELECTED DRAWING: Figure 3
【課題】安定した温度制御ができる湯水混合装置を提供する、【解決手段】湯水混合装置１０は、給水管１Ｃ、給湯管１Ｈ、混合管１Ｍ、流量調節弁４Ｃ，４Ｈ、温度センサ３Ｃ，３Ｈ、流量センサ５Ｃ，５Ｈ、設定部７０、及び制御部８０を備えている。制御部８０は、流量調節弁４Ｃが給水路を開いている大きさを示す水側開度ＶＰｃと、流量調節弁４Ｈが給湯路を開いている大きさを示す湯側開度ＶＰｈと、を比較し、水側開度ＶＰｃと湯側開度ＶＰｈのうち開度が大きい側である給水路及び給湯路のいずれかの流量センサ５Ｃ，５Ｈが取得した流量ＱＣ，ＱＨに基づいて、開度が小さい側の給水路及び給湯路のいずれかの流量調節弁４Ｃ，４Ｈの目標流量ＱＣ１，ＱＨ１を算出して更新し、更新された開度ＶＰｃ，ＶＰｈが小さい側の流量調節弁４Ｃ，４Ｈの目標流量ＱＣ１，ＱＨ１を基準にして開度ＶＰｃ，ＶＰｈが小さい側の流量調節弁４Ｃ，４Ｈを制御する。【選択図】図３
