Patent number: 11788728Abstract: Hot surface igniter assemblies used in cooktops are shown and described. The hot surface igniters include a silicon nitride ceramic body with an embedded, resistive, heat-generating circuit. The igniters are less than 0.04 inches thick, and when energized, they reach surface temperatures in excess of 2000° F. in under 4 seconds to ignite combustible gas such as propane, butane, or natural gas. Examples of cook top burner systems are also provided which allow the igniter to remain on after ignition at a power level that is lower than during ignition but high enough to ignite the cooking gas should a flame out occur. Examples are also provided of burners that ignite on a low flow setting (e.g., simmer) as opposed the high flow settings that are common in cook top industry.Type: GrantFiled: October 4, 2022Date of Patent: October 17, 2023Assignee: SCP R&D, LLCInventors: Jack A. Shindle, Bruce C. Sprowl, Yin Liu

Publication number: 20230128530Abstract: Systems and methods for detecting the presence of a burner flame using flame rectification are shown and described. A conductive flame sensor is positioned to conduct electricity to a burner flame when the burner is lit. The flame provides a conductive path to the burner conductive body and when operatively connected to an alternating current source, half-wave rectifies the current flowing to the sensor. A flame sensing circuit provides an output signal that is conditioned for use as an input to a flame indicator and/or a controller that is configured to shut off gas flow to the burner when no flame is present after an attempt at igniting the burner.Type: ApplicationFiled: October 5, 2022Publication date: April 27, 2023Inventors: Jack A. Shindle, Brian C. Dougherty, James Kelley, Zhan Chen

Publication number: 20220003419Abstract: A cooking gas safety apparatus is shown and described. The apparatus includes a cooking gas safety valve assembly that supplies cooking gas to one or more burners. The cooking gas safety assembly includes at least one coil that is energizable to hold the valve assembly in an open position when subjected to a current that exceeds a threshold value and a hold open circuit. The hold open circuit comprises the coil and a hot surface igniter that is in electrical communication with the coil. The valve assembly is actuated by manually opening the valve and energizing the igniter such that it receives a threshold current that corresponds to an autoignition temperature of the gas. At the threshold current, an electromagnet in the cooking gas safety valve assembly holds the valve open so that it remains open without user intervention. In the event of an igniter failure, the current flow to the coil ceases, causing the valve to shut and cease gas flow to the burner.Type: ApplicationFiled: June 30, 2021Publication date: January 6, 2022Inventors: Brian C. Dougherty, Erik Bothe, Jack A. Shindle, Yin Liu

Publication number: 20210381694Abstract: Hot surface igniter assemblies used in cooktops are shown and described. The hot surface igniters include a silicon nitride ceramic body with an embedded, resistive, heat-generating circuit. When energized, the circuit generates temperatures in excess of 2000° F. in under 4 seconds to ignite cooking gas such as natural gas. To prevent damage to the igniter during use or cleaning, an insulator assembly is provided which protects the distal end of the igniter ceramic body from damage while still exposing it to the cooking gas flow from the burner. In addition, a number of different terminal connection schemes for connecting the igniters to a power source are shown and described.Type: ApplicationFiled: August 23, 2021Publication date: December 9, 2021Inventors: Bruce C.

Publication number: 20210054999Abstract: A thermally-actuatable gas valve assembly comprising a ceramic heater is shown and described. The gas valve assembly comprises a housing with a gas inlet and a gas outlet. A bimetal thermal actuator has a valve plug that removably seals the gas outlet from the interior of the housing. The ceramic heater is energizable to cause the thermal actuator to deflect which unseats the valve plug from the gas outlet, thereby placing the gas outlet in fluid communication with the gas inlet and the interior of the housing. A gas heating system is also shown and described in which the gas valve assembly selectively supplies cooking gas to a silicon nitride ceramic igniter.Type: ApplicationFiled: August 17, 2020Publication date: February 25, 2021Inventors: Jack A.
