Claims
- 1. A controller for an appliance having a plurality of selectively energizeable electromechanical components, comprising:
- input means for operator selection of a desired cycle of operation of said appliance;
- a motor;
- switching means coupled to be driven by said motor and having a plurality of timing cams on a rotating member for controlling the operation of a plurality of switches for applying power to energize said components; and
- sequencing means for selectively advancing said switching means including:
- means for applying power to said motor;
- means on said rotating member for defining incremental positions around said rotating member;
- means for detecting movement of said rotating member from one of said positions to the next adjacent position;
- means separate from said rotating member and reponsive to the selected operation cycle for defining a program for said rotating member which includes a series of operting steps each including a number of incremental positions to be moved and a time delay of operation; and
- means for operating said power applying means to move said rotating member a defined number of incremental positions in accordance with said program.
- 2. The controller according to claim 1 wherein said sequencing means further includes means for timing a defined interval between successive actuations of said power applying means in accordance with said program.
- 3. The controller according to claim 1 wherein said defining means on said rotating member includes:
- a cam track on said rotating member including a plurality of spaced teeth; and said detecting means includes:
- a cam follower associated with said cam track; and
- switching means coupled to said cam follower for providing a first circuit condition when said cam follower is in contact with one of the tips of said teeth and providing a second circuit condition when said cam follower is in contact with one of the roots of said teeth.
- 4. The controller according to claim 1 wherein said sequencing means includes a programmed microcomputer.
