Abstract
A system and method for controlling heater element operation in an oven includes a proportional heater signal generator that is mounted in associated with an oven operational mode switch. The signal generator operates in a sub-interval about a mode indicator to generate a proportional signal for controlling a heater element. The proportional signal may be used to alter the input voltage or timing control of the heater element.
Claims20
A system for controlling a heater element in an oven comprising:
- an oven operational mode selection switch with mode indicators that identify an oven operational mode;
- and
- a proportional heater signal generator that operates in association with the oven functional mode switch to generate a proportional heater element control signal that corresponds to a position proximate of the oven functional mode selection switch within a sub-interval of the operational mode selection switch.
A system for controlling a heater element in an oven comprising:
- an oven operational mode selection switch with mode indicators that identify operational modes for an oven;
- a proportional heater element control signal generator that operates in association with the oven operational mode selection switch to generate a proportional heater element control signal that corresponds to a displayed sub-interval indicia.
A method for proportionally controlling operation of a heater element in an oven comprising:
- identifying an operational mode of an oven;
- and
- generating a proportional heater element control signal that corresponds to a position in a sub-interval associated with the identified operational mode.
