FIG. 5 is an explanatory view illustrating the outline of the structure of the mixing valve 22. As shown in the drawing, the mixing valve 22 has a mixing chamber 30 formed therein, and a mixing valve housing 24.
A movable valve body 32, a bias spring 34, a biasing force adjusting member 38, and a temperature sensitive spring 36. In the mixing valve housing 24, a hot water side port 26 for supplying hot water from the hot water side fitting 16 and a water side port 28 for supplying water from the water fitting 18 are formed in the circumferential direction in the mixing chamber 30. ing. The movable valve body 32 is disposed in the mixing chamber 30, and the opening ratio of the hot water port 26 and the water port 28 to the mixing chamber 30 is adjusted to adjust the mixing ratio of the hot water to the mixing chamber 30. Adjust. The movable valve body 32 is biased to the right side in the drawing by a bias spring 34. At this time, when the handle 40 (see FIGS. 2 and 3) is operated to rotate left and right, the biasing force adjusting member 38 moves in the left and right direction in FIG. 5 to adjust the biasing force of the bias spring 34.
Further, the temperature-sensitive spring 36 is arranged so as to face the bias spring 34 with the movable valve body 32 interposed therebetween, and biases the movable valve body 32 to the left side in the figure via the spring retainer 35.

A communication hole 33 is formed in the center of the movable valve body 32, and the hot water flowing from the hot water port 26 into the mixing chamber 30 passes through the communication hole 33 and flows in from the water side port 28. It is designed to mix with water. Temperature sensitive spring 36
Is formed of a metal material whose spring constant K changes with temperature, such as a shape memory alloy made of a nickel-titanium alloy. In the embodiment, the temperature-sensitive spring 36 is formed of a material whose spring constant K increases as the temperature rises, and the temperature-sensitive spring 36 is urged by the movable valve body 32 to move the hot water port 26 to the hot-water port 26. It is placed in the closing direction.

Therefore, if the temperature of the hot water flowing into the mixing chamber 30 changes due to disturbance or the like, or the temperature of the hot water or the water pressure changes, and the temperature of the mixed hot water changes, the spring constant K of the temperature sensitive spring 36 will change. The temperature of the mixed hot water changes so as to cancel the change, and the movable valve body 32 is moved to keep the temperature of the mixed hot water at the set temperature. That is, when the temperature of the mixed hot water rises, the temperature-sensitive spring 36 increases the spring constant K as the temperature rises.
Is increased, the movable valve element 32 is moved in a direction in which the flow of hot water into the mixing chamber 30 is reduced, and the temperature of the mixed hot water is lowered. Further, when the temperature of the mixed hot water decreases, the spring constant K decreases with this temperature decrease, and the movable valve element 32 is moved in a direction in which the flow of hot water into the mixing chamber 30 increases to increase the temperature of the mixed hot water. Make it higher The mixing valve 22 thus maintains the temperature of the mixed hot water at the set temperature.

Conventionally, a wax thermostat has been used as a member for keeping the temperature of the mixed hot and cold water constant as described above in response to the temperature change of the hot and cold water supplied. In this case, the volume of the wax thermostat changes according to the temperature change of the mixed hot water, and the movable valve body is displaced. A spring formed of a shape memory alloy like the temperature-sensitive spring 36 has a smaller heat capacity than such a wax thermo and can react more quickly to a temperature change of the mixed hot water. Therefore,
By using the temperature-sensitive spring 36 made of a shape memory alloy, it is possible to further improve the stability of the temperature of the mixed hot water discharged.

The Karan water discharge solenoid valve 42A, the first branch water passage solenoid valve 42B and the second branch water passage solenoid valve 42C provided in the water passage to which the hot water mixed by the mixing valve 22 is supplied are
Both are configured as normally-closed solenoid valves that are closed when electric power is not supplied. These solenoid valves are
