PROBLEM TO BE SOLVED: To provide a device capable of suitably and easily regulating a discharge water temperature for any type of combination faucet through electronic control.SOLUTION: A temperature regulation device 1 is so configured that hot water and water having their temperatures regulated through a mixing valve 40 are supplied to a combination faucet 10 through two passages 56, 58 branching off on a downstream side. The combination faucet 10 mixes the hot water and water supplied from the respective passages 56, 58 at a mixing ratio corresponding to a manipulated variable of an operation lever 22. In this constitution, a control part 42 performs temperature regulation control by estimating the manipulated variable of the operation lever 22 on the basis of the flow rate ratio of the two passages 56, 58 on the upstream side of the combination faucet 10. Consequently, the temperature regulation control is substantially not affected by differences in size and shape of the combination faucet 10. A discharge water temperature can be suitably and easily adjusted for any type of combination faucet. |
