HOT-WATER SUPPLYING DEVICE

PURPOSE:To simplify the operations of a water cock and a water amount regulating valve by a method wherein the water amount regulating valve, regulating the water supplying amount in a water path, and a stop valve, opening and closing the water path, are driven by the driving shafts of a common motor. CONSTITUTION:A stop valve 4 and a water amount regulating valve 6 are arranged in parallel substantially in the axial directions thereof and the driving shafts 9, 9' of a driving motor 8 are constituted integrally while the motor 8 s constituted of a stepping motor, moving these driving shafts into the axial direction thereof. Upon delivering hot-water, selecting switches 21, 21... are selected and operated to select and specify a desired cource at first. Subsequently, a start/stop switch 22 is operated whereby a micro-computer 18 reads the hot-water delivery operation through an input port 19b, and controls the rotations of the motor 8 and a proportional control valve 13 through a water amount control circuit 26 and a gas amount control circuit 27. The stop valve and the water amount control valve can be controlled by driving only one set of motor while these operations may be effected simply by ON-OFF operation of an electric switch, for example.
