摘要:
A gas igniter includes a heating element, a bushing and a mounting bracket. The bushing is formed of a generally rigid electrically insulating material and supports the heating element. The bushing includes an elongated slot extending through the bushing. The mounting bracket includes a first connecting portion and a second mounting portion. The first connecting portion is inserted through the elongated slot located on the bushing for connecting the mounting bracket to the bushing. The second mounting portion is configured to attach the gas igniter to an associated support surface.

Systems and methods for energizing a low voltage electrical resistance igniter are disclosed. The systems and methods determine the line voltage into the system and control the voltage being applied to the electrical resistance igniters so a first regulated voltage is applied initially and for a time period and thereafter a second regulated voltage is applied, the second voltage being the operating voltage for the igniter. The systems and methods decrease the amount of time required to heat-up the low voltage electrical resistance igniter to a temperature sufficient to ignite a fuel-air mixture while regulating the output voltage being delivered to the igniters to prevent over voltage damage to the igniters.

An electronic control (8) is shown adapted for use with gas furnaces which controls function and speed(s) of an induced draft motor (44), an igniter source (13), gas valve(s) (14), and function and speed(s) of a blower motor (21) based on inputs from a room thermostat, various sensor and safety devices, and proper sequence/position/change of position timing of these inputs. The control is capable of detecting and saving for recall specific errors and faults that occur while in service. The control can communicate warnings, faults, and errors, as well as safety lock-out conditions in various ways including a Light Emitting Diode (LED) (9), as a generic fault condition through a set of dry contacts (45a), or as very specific fault conditions through a communications interface (H4). The control provides other benefits to the installer, occupants of the space, and service technicians including selectable igniter warm-up times, user selectable fan On speed and blower delay-off times.
摘要:
A gas lamp system and method for lighting the system which utilizes a sparkless flame starter in close proximity to the torch to create a flame. The system further includes a safety control circuit which activates the sparkless flame starter and subsequently actives a gas valve to deliver the gas to the torch after the sparkless flame starter has been energized. The sparkless flame starter is a low-voltage device such as a glow coil which is also arcless.

摘要:
A control system for use in combination with any combustion type heating device to provide a fail-safe safety ignition system. A voltage source, circuit breaker, igniter, electrically actuated fuel source control means and serially connected ignition sensing means, of a material having a high positive temperature coefficient of electrical resistance, are incorporated in the system. The current due to varying resistance of the sensing means will develop from a high initial value to a lower average normal running current value upon satisfactory ignition. The system parameters are selected to automatically disconnect the fuel source in the event of a failure in the combustion cycle. The circuit which includes the sensing means may also include a temperature indicating device.

Methods and systems for a burn proof lighter with a collapsible ceramic tip may include extending, with a switch module, a ceramic heating element beyond a body of an electronic lighter. The method may include adjusting, with a temperature switch, a temperature of the ceramic heating element, wherein the temperature switch may include multiple pre-defined temperature settings. The method may include retracting, with the switch module, the ceramic heating element into the body of the electronic lighter. In an embodiment, the switch module may include a sliding switch. Additionally, the temperature switch may include a plus button and a minus button. In a further embodiment, the multiple pre-defined temperature settings may include a vapor setting, a thick vapor setting, a combustion setting, or a butane lighter setting. In an embodiment, the pre-defined temperature settings may include a low temperature setting, a medium temperature setting, and a high temperature setting.
摘要:
An adaptive gaseous fuel ignition control method for use in consumer and commercial appliances that reduces stress on and increases the life of a hot surface igniter without resulting in a failure to ignite condition is provided. The method provides a preheating period, a full temperature period, and a trial for ignition period. The preheating period gradually increases the power applied to reduce the stress resulting therefrom. Once a gas valve has been commanded open, the controller monitors the time for ignition of the gaseous fuel. If the time is longer than a threshold, either the applied power or the period of time during which the power is applied is increased to shorten the time. If, however, the ignition period is shorter than the threshold, either the power applied or the period of time during which the power is applied before commanding the gas valve open is lowered or shortened.
