Abstract

PURPOSE:To prevent hot water from being discharged when a shower is used, by changing over the destination of discharge to a faucet by the action of a temperature safely valve when the temperature of mixed hot water exceeds a prescribed one. CONSTITUTION:Comparing the temperature detected by a temperature detector 24 with that set by a setting apparatus 25, a controller 26 sends a signal to a mixing valve driving unit 23 in response to the deviation, and controls a mixing valve 20 so that the mixed hot water temperature becomes equal to the setting temperature. The temperature-controlled mixed hot water is discharged from either a shower head 28 or a faucet 29 via a changeover valve 27. When the mixed hot water temperature exceeds a prescribed temperature, the wax inside a wax type thermostat body expands to push out a rod 40. Thus, a safety lever 43 acts on the shower side valve body 31 of the changeover valve 27, and mixed hot water is discharged from the faucet 29.
