Claims
- 1. A burner control for a burner having an ignitor and a gas conduit coupled to a gas source, the control comprising;
- a valve coupled to said gas conduit for selectively delivering a variable volume of gas to said burner from the gas source;
- an actuator having a valve control responsive to manipulation of said actuator throughout a predetermined range,
- an ignitor control for controlling an electrical charge to the ignitor in response to manipulation of said actuator through at least a first portion of said predetermined range; and
- means for periodic sequencing of the flow of gas and the ignitor charge when said actuator is in said first portion of said predetermined range of said control, including a switch responsive to manipulation of said actuator throughout said first portion for adjusting the period of sequencing.
- 2. The invention as defined in claim 1 wherein said means for periodic sequencing comprises at least one control module with a microprocessor.
- 3. The invention as defined in claim 2 wherein said actuator includes a mechanical valve control and said ignitor control comprises a switch for controlling electrical charge to the ignitor in response to manipulation of said actuator through said first portion and a second portion of said predetermined range.
- 4. The invention as defined in claim 3 wherein said switch comprises a potentiometer with a rotor engaged with said mechanical valve control.
- 5. The invention as defined in claim 2 wherein said at least one control module includes a power up cycle check for disabling delivery of said variable volume of gas and said electrical charge unless said actuator is returned to a preset limit of said predetermined range.
- 6. The invention as defined in claim 2 wherein said at least one control module includes an under voltage lockout to disable delivery of said variable volume of gas and said electrical charge if a supply voltage is below a predetermined limit.
- 7. The invention as defined in claim 2 wherein said at least one control module includes a timer for generating periodic sequencing derived from a mains line voltage signal.
- 8. The invention as defined in claim 1 wherein said actuator comprises a single rotary knob.
- 9. A stove having a plurality of burners a source of gas, an ignitor at each burner, and a control channel for at least one of the plurality of burners comprising:
- an actuator having a range of response;
- a valve coupled to said actuator for controlling delivery of a variable volume of gas from said source to its respective burner;
- at least one solenoid valve interposed between the gas source and one said control channel burner;
- an ignitor control coupling said actuator to a respective control channel ignitor; a timer control having a periodic sequencing control output for charging said respective control channel ignitor and controlling said solenoid valve for periodic gas flow to its respective burner;
- wherein said actuator has a switch for actuating and adjusting said periodic sequencing in said timer control in at least a portion of said range of response.
- 10. The invention as defined in claim 9 wherein said actuator comprises a rotary knob.
- 11. The invention as defined in claim 10 wherein said switch comprises a sensor for detecting a predetermined rotary displacement of said knob.
- 12. The invention as defined in claim 11 wherein said sensor comprises a potentiometer.
- 13. The invention as defined in claim 9 wherein said stove comprises at least two control channels having said switch for actuating said periodic sequencing control.
