Utilizes the repulsion force of 19a and magnet 19b. Reference numeral 20 denotes a variable bias unit that applies a variable bias force in opposition to the force of the urging unit 19. The variable bias means 20 has an operating body 21 made of a magnetic material, and a coil 22 that is waterproof and insulated around the operating body 21, and the coil 22 is connected to a variable power supply 23. The strength of the urging means 19 adjusts the rotation of the adjusting operation means 24 having the screw 24a, and the magnet

20の操作力を変更しなくても湯と水の混合比の変化は小
さく湯温は安定している。Next, the operation of the present invention will be described. Coil from external power supply 23
When a current is passed through 22, the operating body 21 made of a magnetic material applies a bias force to the valve shaft 8 according to Fleming's law. When the bias force and the urging force of the urging means 19 are balanced, the automatic pressure regulating valve 3 is balanced. Therefore, the balance point of the automatic pressure regulating valve 3 can be moved by changing the current flowing through the coil 22. For example, when the current is small, the repulsive force of the urging means 19 is stronger, so that the water-side valve body 6 opens more than the hot-water-side valve body 4, and the tapping temperature decreases. When the current is increased, the operating body 21 is pushed out against the force of the urging means 19 to open the hot water side valve body, and as a result, the tapping temperature becomes high. When the water pressure fluctuates, the automatic pressure regulating valve 3 operates as in the related art. For example, when the water side pressure rises suddenly, this inlet water pressure acts equally on the water side valve element 6 and the piston 9, so that the inlet water pressure does not become a force for moving the valve shaft 8, but the water side inlet water pressure increases. The flow rate passing through the water-side valve body 6 increases. Due to the increase in the flow rate, the outlet pressure of the water-side valve body 6 is increased.
Since the pressure PC2 rises, the water pressure acts on the water-side valve body 6 due to the rise of the outlet pressure PC2, and a force acts in a downward direction in the drawing, that is, a direction in which the water-side valve body 6 is to be closed. Suppress the increase. Therefore, if the area of the hot water side valve element 4, the water side valve element 6 and the piston 9 are made substantially equal, the variable bias means
Even without changing the operating force of 20, the change of the mixing ratio of hot water and water is small and the hot water temperature is stable.

として電磁力を発生するものにおいては磁力作用によっ
て水中の磁性体が付着しやすい場合に効果が大きい。The valve shaft 8a on the water side valve body 6 side and the operating body 21 move integrally in the axial direction and the rotation direction. For this reason, the blade 4a as a rotating force generating means for the hot water side valve element 4 and the water side valve element 6
When the valve shaft 8 is rotated by the water flow action by 4b, the operating body 21 is also integrally rotated. The gap between the operating body 21 and the coil 22 is designed to be small in terms of magnetic loss, and dust and scale are likely to adhere thereto, but are removed by the rotation of the operating body 21. Particularly, as in the present embodiment, the variable bias means 23 is used.
In the case of generating an electromagnetic force, the effect is great when a magnetic substance in water easily adheres due to the magnetic force.

作動するので湯温の変動は小さい。When the power supply is stopped due to a power failure or the like, or when control becomes impossible due to some abnormality of the device, the control by the variable bias means 23 cannot be performed. In this case, the hot water temperature can be adjusted by manually rotating the adjusting operation means 24. Even during manual adjustment, when the water pressure fluctuates, the automatic pressure regulating valve 3 operates, so that the fluctuation of the hot water temperature is small.

が小さくなって制御性がよい。Effect of the Invention As described above, the hot and cold water mixing device of the present invention has a hot water flow path and a water flow path, a hot water side valve element and a water side valve element that adjust the flow rates of the hot water flow path and the water flow path, and a hot water side valve body. A valve shaft that opposes the force of the outlet pressure of the water-side valve body to each other, a rotating force generating means that applies rotation by water flow to the valve shaft, an operating body that rotates integrally with the valve shaft, and a bias force is applied to the operating body. Since the variable bias means is provided, dust and scale do not adhere to the operating body, the reliability is high, and the hysteresis due to the sliding frictional force is reduced and the controllability is good.
