Definitions

  • Embodiments of the subject matter described herein relate generally to a system and method for permitting concurrent activation of a gas safety valve and an ignition trigger for igniting gas burners.
  • Gas safety valves are integrated into the cooking apparatus and provide a measure of safety by preventing the outflow of flammable gas if the burner is not lit. Gas safety valves are normally mechanical in nature and require moderate pressures to activate, thus ensuring that any release of flammable gas is a result of a user's purposeful actions.
  • the safety valve To light the burner, the safety valve must first be activated to start the flow of flammable gas.
  • An ignition source ignites the flammable gas. Once the flammable gas is lit the gas safety valve permits the continued supply of flammable gas without requiring continuous activation of the gas safety valve.
  • the user In commercial cooking apparatuses it is common for the user to first light a pilot for the gas burner, and the pilot ignites the gas burner. To light the pilot, the user first starts the flow of flammable gas by manually pressing and holding a button in the gas safety valve. The user ignites the flammable gas by pressing a button on an ignition source, such as a piezo-ignition device or electronic ignition module.
  • the ignition source is typically a piezoelectric device or an electric starter that creates a high voltage spark, but could also utilize a heated filament or other ignition device.
  • the gas safety valve and the ignition modules are two different devices, the user typically uses two hands to perform the lighting function.
  • the gas safety valve and ignition device are separated by a distance that makes it impossible for a user to press both buttons with one hand.
  • the pressure required to depress the button of a gas safety valve may require a substantial pressure that makes it difficult to also press a button on the ignition source in a coordinated fashion using only one hand. This is especially true for piezoelectric igniters, which generally require a substantial amount of mechanical pressure to trigger. For these reasons, a user typically depresses the button on the gas safety valve safety with a finger or thumb of one hand, and uses a finger or thumb of the other hand to depresses the button of the ignition source.
  • buttons can be difficult for some handicap users who do not have the use of both arms and hand. Even for users having the use of both arms and hands, there are instances when pressing both buttons can be difficult. If the user is carrying anything in one hand, it must first be set down so that both hands are free to press the buttons. For example, if the gas burner is part of a furnace or boiler in a dimly lit basement and the user happens to be holding a flashlight with one of their hands, the user having to use both hands to light the furnace or boiler might have difficulty keeping the light pointed on the buttons while performing the lighting operation. In another example, a chef carrying a pan with ingredients to be cooked must first set down the pan prior to lighting the stove. This creates the potential incentive to keep the burner on when it is not in use or forces the chef to set down a pan in order to light the burner, not only slowing the chef down, but also slightly increasing the likelihood of an accidental spill.
  • the combination safety valve and ignition device for gas burners permits both the start of a flow of flammable gas to a burner and the ignition of the flammable gas operation of a single button or other actuator.

  • the pilot outlet port is connected via a pilot gas flow path to receive flammable gas from the gas inlet port, the second valve controlling flow of flammable gas along the pilot gas flow path.
  • the pilot outlet port is connected via a pilot gas flow path to receive flammable gas from a pilot gas inlet port of the body, the pilot gas inlet port separate from the gas inlet port, the second valve controlling flow of flammable gas along the pilot gas flow path.
  • the safety actuator may be a push-button type actuator that has either (i) an associated arm or other structure that triggers the ignition switch that is located external of the valve body (e.g., in a housing connected to the valve body) or (ii) an internal portion that triggers the ignition switch (e.g., a membrane switch) that is located internal of the valve body.
  • a gas powered device includes the safety valve of such aspect or implementation and further includes a pilot; an ignition module in electrical or mechanical communication with the ignition switch; an ignitor; wherein the pilot receives flammable gas from the pilot output port when the safety actuator is operated to open the second valve; and wherein operation of the ignition switch when the safety actuator is operated triggers the ignition module to send an electrical impulse to the ignitor to create a spark that ignites the flammable gas of the pilot.
  • the device may further include a thermal sensor proximate the pilot, wherein the thermal sensor is connected to deliver an electrical signal to the first valve in response to ignited flammable gas of the pilot, the electrical signal for holding the first valve open.
  • the thermal sensor may be a thermocouple or a thermopile.
  • the ignition module may be connected to a power source through the ignition switch or (ii) an output of the ignition module may be connected to the ignitor through the ignition switch.
  • a system in another aspect, includes a gas control unit having an inlet port for accepting a gas; a outlet port in the gas control unit for transferring the gas to a burner, the outlet port in fluid communication with the inlet port; a valve for selectively transferring flammable gas from the inlet port to the outlet port; a safety actuator that when operated opens the valve; and a switch in communication with the safety actuator, the switch transitions to an operating state when the safety actuator is operated.
  • a method of starting a burner involves: operating a safety actuator on a safety valve a first distance, the safety actuator mechanically opening a first valve to allow a flammable gas to flow to a pilot burner; operating the safety actuator on the safety valve a second distance, the safety actuator triggering a switch to transition between an open state and a closed state, the switch in electrical or mechanical communication with an ignition source, the ignition source triggering an electrical impulse that causes a spark at the pilot burner, the spark igniting the flammable gas creating a flame; heating a thermal sensor using the flame to generate an electrical signal; the electrical signal activating a second valve that controls whether flammable gas flows to a primary burner; and releasing the safety actuator on the safety valve so as to open the second valve.

  • the gas burner unit 100 may also be integrated within a housing for baking or broiling food product, depending upon the particular kind of commercial cooking equipment.
  • the flammable gas will not freely flow to the gas burners 106 by merely turning the flow valves 124 unless there is already a flame present at the pilot 114 so that the upstream safety valve 104 is energized and held open.
  • the pilot 114 is a small flame positioned in close proximity to one or more of the gas burners 106. There may also be multiple pilots 114, for example one pilot 114 for each gas burner 106. When lit, the pilot 114 provides a constant flame to ignite flammable gas flowing into the gas burners 106. The flame of the pilot 114 is also directed at a thermocouple 122 that provides power to keep the safety valve energized.
  • the safety valve 104 is pressed allowing flammable gas to temporarily flow out of the pilot 114 while the safety valve is continuously pressed. While the flammable gas is flowing out of the pilot 114, the user ignites the flammable gas using an ignition source.
  • the ignition source can be a match, or lighter, but is preferably an ignition module 108 comprising a piezoelectric spark generator or an electrical spark generator.
  • the ignition module 108 sends an electrical impulse to the ignitor 116. Between the ignitor 116 and the pilot 114 there is a small gap, called a spark gap, in close proximity to, or in the direct path of, where the flammable gas exits the pilot 114.
  • thermocouple 122 is electrically connected to the pilot 114 and the electricity from the thermocouple 122 energizes the safety valve 104 to permit flow to both the pilot 114 and the flow valve 124 that feeds the gas burner 106. As long as the thermocouple 122 is interacting with the flame, the safety valve 104 stays energized permitting such flow.
  • the pilot 114 will generally stay lit until the flammable gas is removed or the flame is extinguished. Because the safety valve must be energized to permit flow to the gas burners 106, the pilot 114 must be lit before the user can turn on the gas burners 106 using the flow control valves 124.
