Definitions

  • This invention comprises various improvements made on instant lighting devices in built-in safety valves based on flame control, used in gas operated household appliances or any other industrial appliance containing one or more burners.
  • thermoelectric type a thermocouple that uses electrical energy to generate electrical energy to the heating of a thermocouple, either by the flame of a pilot light, or by the bumer itself.
  • the electrical energy generated flows through the coil of an electromagnet assembly, and this action makes it possible for safety valve to remain open, allowing for the flow of the gas to the burner it controls.
  • the valve controlling the flow of the gas closes.
  • the magnetic force of attraction should only be slightly greater than the force of the tension caused by the spring of the safety valve; this level of force is achieved with very low consumption of electrity.
  • the invention is based on the fact that once the control knob of the device is in position for lighting, at the same time that the rod is pressed, thus activating the valve with the magnetic group, a contact, or electric microswitch is established which sets off the time-delayed spark lighter and the flow of an auxiliary current to the magnetic group, timed to replace for a few seconds the electrical current which will then be generated by the thermocouple once the latter is heated.
  • the instant lighting device, object of the invention consists of the following:
  • a selector to support the above function in the event that the circuit to be fed consists of more than one valve.
  • the lighting system may be operated in two different manners; that is, by time delay or by ionization of the flame.
  • Time delayed lighting is effected when the microswitch or button is activated and gives the signal beginning from zero, in which case the spark lighter is in operation for 5 seconds, and at the same time, the auxiliary current source to the thermocouple is activated for approximately 6 to 11 seconds.
  • the time difference between the 5 seconds that the spark lighter is activated to light the gas, and the 11 seconds for allowing the auxiliary energy supply to reach the magnetic group, is approximately 6 seconds. This is the amount of time necessary to heat the thermocouple and generate the current needed to substitute the auxiliary energy being used.
  • Lighting by means of flame ionization is carried out as follows.
  • the spark lighter and the auxiliary electrical current the magnetic thermocouple group are set off, and the pilot and(or burner is lit.
  • a flame is produced, and by means of the effect of ionization, a signal is received indicating that the flame is burning, at which point the spark lighter stops functioning.
  • a timer is set off, which after 6 seconds, cuts off the supply of the auxiliary electrical current to the thermocouple and magnetic group.
  • the device may be used either connected to the house electrical current, or, as a temporary measure, without external electrical energy. And lighting takes place instantly and immediately without the need for continuous pressing of the control button while the gas is being lit and the thermocouple is being heated.
  • thermocouple which generates the energy necessary to keep the safety valve open, cools off, and the energy produced decreases.
  • the energy decreases to approximately 1/3 the absense of the flame is detected, and the circuit stops functioning automatically.
  • the safety valve closes, preventing the flow of gas to the pilot or burner(s).
  • thermocouple While the thermocouple is being heated, the circuit remains out of operation, even if the lighting system is activated, thus no energy is consumed.
  • the device (1) consists of a printed circuit (2) which includes a set of pushbuttons (3) by means of which the valves controlling the flow of gas to the burner (not shown for the appliance for household use), are activated.
  • the circuit is equipped with a selector (5), so that by means of a trigger (6), a single valve may be selected for use with the corresponding supply.
  • the supply source (8) can be used with a storage cell, and can also be connected to the circuit by an isolation transformer (9).
  • Both the isolation transformer and the thermocouples (4) together with the spark lighter (7), are controlled by means of timers (10), and in both cases operate on transistors (11).
