Washing appliance control circuitry

Abstract

An appliance control circuit particularly adapted for controlling a washing appliance such as a washing machine or a dishwasher is provided. The invention is comprised of a timer interval selector switch including a program cam defining an operational cycle for operation of the washing appliance. A hybrid timer control circuit including an escapement device and a memory and logic circuit is provided for amending advancement of the program cam during operation of the appliance. The escapement device includes a timer interval selector switch in association with the program cam for generating selective binary coded control signals. A binary-coded-decimal to decimal decoder/driver decodes the binary signals into decimal signals which are operatively connected to a plurality of selected capacitance means and an interval timer. The interval time base interval between advancement steps of the program cam is determined by selection of particular capacitance means. The memory and hybrid timer logic control circuit includes program selector switches which may be compared in the logic circuitry with the program cam for selectively rapidly advancing the program cam in accordance with the particular selected program defined by the selector switch.
