PURPOSE:To enable a massage effect to be applied during use of shower by a method wherein a driving device for making a variable desired water volume in a water volume control unit is driven by a signal from the signal producing unit and the water volume is varied within a range of desired water volume in reference to a variation in time. CONSTITUTION:Signals from an incoming water temperature sensor 22 and an output water temperature setting part 28 are calculated in a water volume initial control unit 30a and then the desired water volume in the water volume control unit 1 is outputted at the driving unit 21. Then, when a switch 33 is closed by an operator after the hot water temperature is stabled, a signal is taken out from a memory unit 32a, amplified at a signal producing unit 32, transmitted to the driving unit 21 to cause an adjusting valve 17 to be rotated in a normal or reverse direction. A throat in valve hole is varied under rotation of an adjusting valve 17, a differential pressure in the valve holes is acted upon the diaphragm 7 to drive a control valve 4 and thereby a water volume is varied. The water volume is varied in sequence in response to the signal sent by the signal producing unit 32. |
