Drier appliance control

Claim 1

In a drier appliance having a heating means including an electrical component, thermostat switch means connected in series with said component for operating said heating means as an incident of the temperature sensed by said thermostat means being below a preselected temperature, a timer including a timer motor, a control switch connected in series with the motor for controlling operation of the timer, and means for electrically connecting the appliance to a power supply having a preselected voltage for effecting operation of the appliance, the improvement comprising a capacitor connected from between said timer motor and said control switch to between said thermostat means and said electrical component for connecting said timer motor in series with said electrical component through said capacitor when the control switch is open, said capacitor further connected between the timer motor and the thermostat switch means with said timer motor and said capacitor being effectively shorted by the thermostat switch means when the thermostat switch means is closed to energize said electrical component, said series arrangement of the timer motor, capacitor, and electrical component being connected to have the power supply voltage applied thereacross when the thermostat switch means and control switch are open, the capacitance of said capacitor being preselected to form with the inductance of said timer motor a series resonant circuit condition when said thermostat switch means and said control switch are open wherein the voltage across said timer motor is at least the minimum operating voltage of said timer motor and the voltage across the electrical component is less than the minimum operating voltage necessary to cause effective heating operation of said heating means.
