Abstract

An improved gas burner control system which eliminates the need for a pilot light for operation of a gas burner, including a pair of gapped electrical conductors forming a set of ignition points disposed adjacent to a gas burner, a sensor for detecting the presence of the gas to be burned via the gas burner adjacent to the gas burner, means for electrically coupling the sensor means to a relay, the relay controlling the delivery of electrical current to a second relay, the second relay operable in an alternating fashion, means for electrically interconnecting the points of the alternating relay to the pair of ignition points, means for electrically controlling the flow of gas to the gas burner concurrently with the sensing of the existence of gas flowing out of the gas burner by the gas sensor, the alternating relay being operable upon the detection by the sensor means of the flow of gas from the gas burner, remote means for visually indicating if the electrically controlled valve is open, and means for indicating temperature.

Dependent claims

An improved gas burner control system which eliminates the need for a pilot light for operation of a gas burner, comprising:

(a) A source of gas;
(b) A gas burner;
(c) Electrically operable valve means operably interconnected between the source of gas and the gas burner for controlling the flow of gas therebetween;
(d) Temperature sensing and valve control means for detecting temperature of the operatively associated with the valve, environment, and for controlling the valve relative to the temperature detected;
(e) A pair of gapped electrical conductors forming a set of ignition points disposed adjacent to the gas burner;
(f) A gas sensor for detecting the presence of gas eminating from the gas burner to be burned disposed adjacent to the gas burner, the gas sensor controlling an electrical signal characteristically indicative of the presence or absence of gas therefrom;
(g) Means for electrically coupling the sensor means to a first relay, the first relay being complementarily responsive to the electrical signal from the gas sensor;
(h) Means for electrically powering the first relay;
(i) A source of electrical energy operatively associated with the first relay, whereby the first relay controls the transfer of the electrical energy;
(j) A second relay operatively associated with the first relay for receiving the transfer of electrical energy therefrom and for controlling the deliverty thereof, in alternative fashion, to the pair of ignition points;
and
(k) Means for operatively coupling the output of the second relay to the pair of points.
