る。In the hot and cold water mixing valve 1 having the above-mentioned structure, the cold water that has entered the valve chamber 22 from the cold water inlet 23 hits the cylindrical portion 32 of the spool 29 and flows into the inside of the spool 29 through the communication hole 33. It is mixed with hot water at and then flows toward the shape memory alloy spring 35. Therefore, since the cold water does not directly hit the shape memory alloy spring 35, it is possible to prevent the shape memory alloy spring 35 from malfunctioning. Further, hot water does not directly contact the shape memory alloy spring 35, so that the shape memory alloy spring 35 can be prevented from malfunctioning. This effect is further increased by extending the spool 29 in the other end direction and distant the shape memory alloy spring 35 from the cold water inlet 23 and the hot water inlet 24, so that heat conduction by the spool 29 is also avoided. . Further, the spool 29, which has a cylindrical thin hollow shape as a whole, allows the mixed water to easily flow inside the spool 29 (less resistance), and because the pressure receiving area in the moving direction of the spool 29 is small, the spool 29 is pressed by water pressure. There is an advantage that it is difficult to move.

圧に押されて移動しにくいメリットがある。That is, in the hot and cold water mixing valve of the present invention, the cold water that has entered the valve chamber from the cold water inlet hits the cylindrical portion of the spool and flows into the inside of the spool through the communication hole.
Here it is mixed with hot water and then flows towards the shape memory alloy spring. Therefore, since the cold water does not directly contact the shape memory alloy spring, it is possible to prevent the shape memory alloy spring from malfunctioning. Also for hot water, since it does not directly hit the shape memory alloy spring,
It is possible to prevent the shape memory alloy spring from malfunctioning. Further, since the mixed water easily flows inside the spool having a thin cylindrical hollow shape as a whole, and the pressure receiving area of the spool in the moving direction is small, the spool is pushed by the water pressure and is difficult to move.
