Then, even if the pressure of the hot water or water suddenly changes, the automatic pressure regulating valve 3 moves by the pressure, and acts so that the secondary pressure PH2 of the hot water and the secondary pressure PH2 of the PC are always equalized. Further, the valve shaft 8 is provided with biasing means 10. The bias means 10 is composed of a bobbin 11 connected to the end of the valve shaft 8, a coil 12 wound around the bobbin 11, and a permanent magnet 13 provided so as to surround the coil 12.

To be done. As a result, the automatic pressure adjustment point is displaced by the amount of the bias force, and for example, the secondary pressure PH2 of the hot water and the water is constantly adjusted at the point of 2: 1 so that the mixed hot water having a predetermined temperature is discharged. The temperature of the mixed hot water can be changed by changing the current flowing to the coil 12 in this manner.

7 starts tapping at a temperature lower than the set temperature Ts by a predetermined value ΔT by the temperature T1 set by the lower limit hot water temperature setting means 56. That is, at time x, when the hot water discharge start signal generating means 54 outputs a hot water discharge signal, the timer means 55 starts to operate and the first hot water temperature changing means 57 sets the normal hot water temperature set by the hot water temperature setting means 17. A temperature T1 which is lower than the medium set temperature Ts by a predetermined value ΔT is input from the lower limit hot water temperature setting means 56 and set as the set temperature at the start of tapping. When the first hot water temperature changing means 57 inputs by the timer means 55 that the time t7 has elapsed from the start of hot water discharge, the temperature difference between the set temperature Ts and the lower limit temperature T1 is raised within a preset time (here, time t8). The calculation is performed to raise the temperature, and the temperature is raised to the set temperature Ts.

うにしている。Here, when the temperature of the hot water is slow to rise at the start of hot water when using a shower or the like, the feeling of stimulation is lacking, but in the present embodiment, a hot water start signal generating means 54 outputs a hot water start signal. Then, the flow rate control valve control means 46 controls the flow rate control valve drive means 21 through the second drive amount setting means 47 to open the flow rate control valve 20. In this case, the set temperature is the temperature Ts set by the hot water temperature setting means 17.
Instead, the temperature reaches the temperature T1 set by the lower limit hot water temperature setting means 56, and the signal from the timer means 55 causes the first hot water temperature changing means 57 to temporally raise the temperature T1 by a predetermined value ΔT1 higher than the temperature Ts. The temperature is changed so as to approach the temperature set by the setting means 58. Then, after the hot water temperature reaches the upper limit hot water temperature T2 and a certain period of time elapses, the second hot water temperature changing means 59 changes the temperature to approach the temperature Ts.

度を変更する。This hot water discharge characteristic will be described with reference to FIG. FIG. 13 (a) shows the hot water discharge characteristics of the conventional example, and the set temperature is the set temperature Ts set by the setting means 17 during normal hot water discharge.
Is. For this reason, the hot water temperature at the start of tapping may be higher than the body temperature. On the other hand, in the hot water discharge characteristics of the present embodiment shown in FIG. 13 (b), the first hot water temperature changing means 57 sets the temperature T1 set by the lower limit hot water temperature setting means 56 to a predetermined value from the set temperature Ts at the start of hot water discharge. The tapping is started at a temperature lower by the value ΔT1. That is, at time x, when the hot water discharge start signal generating means 54 outputs a hot water discharge signal, the timer means 55 starts to operate and the first hot water temperature changing means 57 sets the normal hot water temperature set by the hot water temperature setting means 17. A temperature T1 lower than the medium set temperature Ts by a predetermined value ΔT1 is input from the lower limit hot water temperature setting means 56 and set as the set temperature at the start of hot water discharge. When the first hot water temperature changing means 57 inputs by the timer means 55 that the time t9 has elapsed from the start of hot water discharge,
The set temperature is calculated by eliminating the difference between the temperature T2 that is higher than the set temperature Ts input from the upper limit hot water temperature setting means 58 by a predetermined value ΔT2 and the lower limit temperature T1 within a preset time (time t10 here). change. Then, when the hot water temperature reaches the temperature T2, the process is transferred to the second hot water temperature changing means 59, and the second hot water temperature changing means 59 has a temperature ΔT1 higher than the set temperature Ts for a certain time (here, time t11). After maintaining the temperature T2, the set temperature is changed so that the difference between the set temperature Ts and the temperature T2 is eliminated within a preset time (here, time t12).

してそのまま出湯するようにしている。On the other hand, in this embodiment, when the hot water discharge start signal generation means 54 outputs a hot water discharge start signal, the flow rate control valve control means 46 causes the second drive amount setting means 47 to control the flow rate control valve. The drive means 21 is adjusted to open the flow rate control valve 20. In this case, normally, the set temperature is the hot water temperature setting means 1.
The temperature T1 set by the lower limit hot water temperature setting means 56 is not the temperature Ts set by 7 and the first hot water temperature changing means 57 temporally brings the temperature T1 close to the temperature Ts by the signal of the timer means 55. To change. However, when the temperature Ts set by the hot water temperature setting means 17 is equal to or near the temperature T1 preset in the lower limit hot water temperature detecting means 60, the lower limit hot water temperature detecting means 60 sends a signal to the timer means 55. Then, the set temperature Ts is set as the hot water discharge temperature and the hot water is discharged as it is.

を設定温度Ｔｓに変更して出湯させる。The tapping characteristics will be described with reference to FIG. When a signal is output from the hot water discharge start signal generating means 54 at time x, the set temperature Ts by the hot water temperature setting means 17 is sufficiently higher than the lower limit temperature T1 of the lower limit hot water temperature setting means 56.
Therefore, the lower limit hot water temperature detecting means does not send a signal to the timer means 55, and raises the hot water discharge starting temperature from a temperature lower than the set temperature Ts with time and discharges hot water as shown in the seventh and eighth embodiments. However, if the set temperature Ts is equal to or close to the lower limit temperature T1 when the signal is output from the hot water discharge start signal generating means 54 at time y, the hot water is discharged at a temperature lower than the lower limit temperature T1 by a predetermined value ΔT1. When starting, cold water will be discharged and discomfort will occur. In order to eliminate such a problem, the lower limit hot water temperature detecting means 60 detects that the set temperature Ts of the setting means 17 is equal to or near the lower limit temperature T1 and sends a signal to the timer means 55. Then, the first hot water temperature changing means 57 changes the hot water temperature to the set temperature Ts in response to the signal from the timer means 55, and the hot water is discharged.

Even if the hot water is set to be equal to or near that, the hot water starts to flow with Ts as the set temperature at the start of hot water, so that cold water does not come out and it is possible to use with confidence.
