摘要： An ignition device of a gas cooktop, and a gas cooktop. The ignition device of the gas cooktop includes a discharge end, a receiving end and an ignition control module. An ignition frequency generated by the ignition control module is within a range of [15 kHz, 22 kHz], a distance between the discharge end and the receiving end is within a range of [2 mm, 5 mm], and at ignition, a continuous arc is generated between the discharge end and the receiving end to ignite gas. When the ignition device of this scheme is ignited, an ignition sound is extremely low and there is no noise pollution.

摘要： 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 cooking 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.

摘要： An apparatus, cooking appliance and method functionally verify a gas burner that is controlled by two or more electronically-controlled gas valves coupled in series with one another. Functional verification is performed during ignition and/or shut off of the gas burner at least in part by sequencing the activation and/or deactivation of the gas valves and testing the ignition state of the gas burner while one of the valves is activated and the other is deactivated.

摘要： A gas burner assembly for a cooktop appliance includes a flame ring comprising a plurality of flame ports arranged in an annular array. An outer ring and an inner ring collectively define each flame port of the plurality of flame ports. The outer ring and the inner ring are concentrically aligned and concentrically mated. As a result of this arrangement of the outer ring and the inner ring, the plurality of flame ports are defined by the outer ring and the inner ring. The plurality of flame ports extend radially between the inner ring and the outer ring.

摘要： A system for igniting a grill can include a solenoid valve, a flame rectification sensor, an igniter, and a control circuit connected to the solenoid valve and the flame rectification sensor. The solenoid valve controls flow of gas to the grill's burner and includes a switch that closes when a handle connected to the switch opens the solenoid valve. The control circuit sends current to the solenoid valve when the switch is closed to hold the solenoid valve open. After the switch closes, the igniter is ignited. After ignition, the control circuit monitors the presence of a flame with a flame rectification sensor. If no flame is detected after a certain amount of time, the control circuit stops sending current to the solenoid valve to close the solenoid valve.

摘要： A burner system for a cooking device has at least one burner surface wherein the at least one burner surface is designed in such a way that the burner system has a low minimum power density with homogeneous temperature distribution at the same time. In a first aspect, the burner system includes a fuel supply and a first burner surface for burning the fuel that is provided downstream of the fuel supply. The burner system includes a second burner surface for afterburning that is separate from the first burner surface and is provided downstream from the first burner surface. Moreover, a method for operating the burner system is shown.

摘要： Gas cooking appliance including at least one burner and an ignition device configured to ignite the burner. The ignition device includes a pulse generator configured to send at least one electric pulse for the purpose of generating a spark to ignite the burner. The cooking appliance also includes a flame detector configured to detect the presence/absence of a flame in the burner. The pulse generator is in electrical contact with a part of the burner and the flame detector is connected to ground. The cooking appliance further includes insulating means that insulates the burner with respect to ground, such that when the pulse generator sends at least one electric pulse, an electric spark capable of igniting the burner is generated between the burner and the flame detector.
