PURPOSE:To enable the changing of the temperature of a delivery hot water smoothly by eliminating an overshoot phenomenon of the temperature of showering in the altering of a set temperature in a shower apparatus which has a thermowax type electric mixing valve to allow the altering of the showering temperature with a setting switch. CONSTITUTION:A detection means (c) is provided to detect the presence of a showering delivery hot water and a temperature control signal output means (d) to determine a temperature control signal to be supplied to an electric mixing valve (a) according to a set temperature value from a switch (b) for setting the showering temperature. When a set temperature is changed during the delivery of a showering hot water by the temperature control signal output means (d), the size of the temperature control signal is changed by multiplying a value after the change from the value before it by a specified time. |
