Disclosed is an apparatus for controlling an electric clothes dryer having an electrical heater arranged to be supplied with electric power from a power source to generate heat so as to dry clothes by air heated by the heater, the apparatus comprising a switching device for opening/closing an electrical connection between the power source and the heater in response to a control signal, a voltage detecting circuit for detecting a voltage of the power source and for generating an overvoltage signal when the detected voltage exceeds a predetermined value, and a control signal generating circuit responsive to the overvoltage signal for generating the control signal for turning on/off the switching device. The control signal is formed so that the opening period of the switching device corresponds to the value of the overvoltage signal. Further, the opening period of the switching device is selected the value of power consumption per unit time of the heater always becomes a predetermined value in the case where the supply of power to the heater from the power source is stopped during the opening period of the switching device. |
