PURPOSE: To provide a massage effect when a shower is used and to express the variation in a water quantity by a sound wave by varying the water quantity in a timing manner and generating the wave in synchronization with the variation in the water quantity.
CONSTITUTION: When water is started to be fed, water fed into a water quantity controller 1 is flowed through a water quantity regulation valve 10 to a heat exchanger 11, heated and supplied externally from a hot water output tube 12. A signal is fed from a signal generator 17 to a drive motor 15, and the valve 10 is rotated normally or reversely. The throttle of a valve hole 10a is varied by the rotation of the valve 10, the differential pressure of the hole 10a is acted on a diaphragm 7 to drive a control valve 4, thereby altering the water quantity. Thus, the water quantity is varied in a timing manner. The variation in the water quantity is detected by a water quantity sensor 19, a sound generator 21 is driven by a sound wave generator 20, and the variation in the water quantity is expressed by sound.
