When in use, the user must hold the piezoelectric ignition switch in the depressed position after the presence of the ignition flame, and then release the piezoelectric ignition switch after the presence of the desired burner flame. In case the burner flame and/or the igniting flame is extinguished by wind or an accident, the user must depress the piezoelectric ignition switch and then rotate it from the off-position to the on-position again to ignite the ignition flame so as to further ignite the burner flame.

Thegas inlet 20 is connected to gas source, and mounted with awire gauze filter 47 adapted to remove solid matter from fuel gas passing through thegas inlet 20. Thefirst gas outlet 21 is connected through asubsidiary gas pipe 71 to theignition flame nozzle 72 of the gas burner. Thesecond gas outlet 22 is connected through amain gas pipe 73 to the burnerflame nozzle tube 74. Themain valve assembly 12 is comprised of a plurality ofsolenoid valves close valves electronic igniter 8, and synchronously switched to open the gas passage from thegas inlet 20 to thegas path 19. The ignitionflame control valve 15 is electrically connected to theelectronic igniter 8, and adapted to control the gas passage from thegas path 19 to thefirst gas outlet 21. Theoperation unit 5 comprises a highflame control switch 52, a mediumflame control switch 53, and a lowflame control switch 54. The highflame control switch 52 of theoperation unit 5 controls the high flowrate control valve 16 to close/open the gas passage from thegas path 19 to thesecond gas outlet 22, for enabling a high flow rate of fuel gas to pass from thegas path 19 to thesecond gas outlet 22 and then from thesecond gas outlet 22 through themain gas pipe 73 to the burnerflame nozzle tube 74 for burning and for producing a high intensity of burner flame.

Thepower switch 51 controls the supply of electricity to theelectronic igniter 8. The highflame control switch 52 is electrically connected to the high flowrate control valve 16, and adapted to close/open the high flowrate control valve 16. The mediumflame control switch 53 is electrically connected to the medium flowrate control valve 17, and adapted to close/open the medium flowrate control valve 17. The lowflame control switch 54 is electrically connected to the low flowrate control valve 18, and adapted to close/open the low flowrate control valve 18. Further, the flame control switches 52˜54 form alinkage switch 55, i.e. when switched on the highflame control switch 52, the mediumflame control switch 53 and the lowflame control switch 54 are automatically switched off; when switched on the mediumflame control switch 53, the highflame control switch 52 and the lowflame control switch 54 are automatically switched off; when switched on the lowflame control switch 54, the highflame control switch 52 and the mediumflame control switch 53 are automatically switched off. Because thelinkage switch 55 is of the known art, no further detailed description is necessary. - The operation control of the gas burner is outlined hereinafter with reference to FIG. 4. When switched on the
power switch 51 to electrically connect theelectronic igniter 8, the main valve assembly 12 (i.e., the normal-close valves 13 and 14) and the ignitionflame control valve 15 are opened (The respective valve plugs 23˜25 are opened), enabling fuel gas to pass in proper order through thefuel gas path 19, the ignitionflame control valve 15, thefirst gas outlet 21 and thesubsidiary gas pipe 71 to theignition flame nozzle 72, and at the same time sparks are discharged through the dischargingelectrode 82 to ignite the desired ignition flame. After the presence of the desired ignition flame, the sensor, referenced by 83, gives a signal to theelectronic igniter 8, causing it to stop discharging high voltage through the dischargingelectrode 82. At the same time, thesensor 83 connects power supply to thelinkage switch 55. When the user switches on one of the flame control switches, for example, the highflame control switch 52, the high flowrate control valve 16 is energized to open thevalve plug 26, enabling a high flow rate of fuel gas to pass through the high flowrate control valve 16 to thesecond gas outlet 22 and then the burnerflame nozzle tube 74 for burning and for producing a high intensity of burner flame. - When the temperature of the room surpassed a predetermined level, as shown in FIG. 5, switch on the medium
flame control switch 53 to open thevalve plug 27 of the medium flowrate control valve 17 and to simultaneously switch off the highflame control switch 52 and the lowflame control switch 54, causing the highflame control switch 52 and the lowflame control switch 54 to close the high flowrate control valve 17 and the low flowrate control valve 18. At this time, fuel gas passes through the medium flowrate control valve 17 to the burnerflame nozzle tube 74 for producing a medium intensity of burner flame while the ignition flame is maintained available. - When changing the burner flame to the low intensity, as shown in FIG. 6, switch on the low
flame control switch 54 to open thevalve plug 28 of the low flowrate control valve 18 and to simultaneously switch off the highflame control switch 52 and the mediumflame control switch 53. At this time, the high flowrate control valve 16 and the medium flowrate control valve 17 are closed, and fuel gas passes through the low flowrate control valve 18 to the burnerflame nozzle tube 74 for producing a low intensity of burner flame while the ignition flame is maintained available. - As indicated above, the operation of the present invention is to switch on the
power switch 51 to produce the desired ignition flame, and then to switch on the highflame control switch 52, mediumflame control switch 53 or lowflame control switch 54 for letting fuel gas pass through the high flowrate control valve 16, medium flowrate control valve 17, or low flowrate control valve 18 to the burnerflame nozzle tube 74 for producing the desired high intensity of burner flame, medium intensity of burner flame, or low intensity of burner flame. This operation is as easy as switching on/off an indoor lamp switch. - Referring to FIG. 2, a
receiver 57 and aremote controller 58 may be used instead of theswitches 51˜54 of theoperation unit 5. Thereceiver 57 is installed in theburner body 7 and electrically connected to theelectronic igniter 8 and thecontrol unit 1. Theremote controller 58 is controlled to output control signal by radio to thereceiver 57, causing the receiver to turn on/off theelectronic igniter 8 and close/open thesolenoid valves 13˜18. - In the embodiment shown in FIG. 3, the gas
burner control system 10 further comprises a temperature sensor. The probe of the temperature sensor is set in the desired detecting area (either inside or outside the burner body 7). Thecontacts 56 of the sensor are respectively connected to theelectronic igniter 8 and thelinkage switch 55. When the temperature of the room surpassed the set temperature level, thecontacts 56 are disconnected to cut off power supply from the highflame control switch 52, the mediumflame control switch 53, or the lowflame control switch 54, to further close the high flowrate control valve 16, the medium flowrate control valve 17, or the low flowrate control valve 18, preventing fuel gas from passing to the burner flame nozzle tube 74 (the ignition flame is maintained available). If the burner flame extinguished accidentally and the temperature of the room dropped below the set level, thecontacts 56 are connected to turn on the highflame control switch 52, the mediumflame control switch 53, or the lowflame control switch 54, to further open the high flowrate control valve 16, the medium flowrate control valve 17, or the low flowrate control valve 18, for producing the desired high intensity, medium intensity, or low intensity of burner flame. - Alternatively, the
contacts 56 can be respectively connected to theelectronic igniter 8 and the power switch 51 (see FIG. 7). In this case, thecontacts 56 are disconnected to cut off power supply from theelectronic igniter 8 and to extinguish the burner flame and the ignition flame when the temperature of the room surpassed the set level. On the contrary, when the temperature of the room dropped below the set value, thecontacts 56 are connected to turn on theelectronic igniter 8, resuming the original operation status before power off. - In the embodiment shown in FIG. 7, the high flow
rate control valve 16 of the aforesaid first embodiment (FIG. 3) is eliminated, and the medium flowrate control valve 17 and the low flowrate control valve 18 are incorporated to substitute for the function of the high flowrate control valve 16. To fit this change, the highflame control switch 52 is electrically connected to the medium flowrate control valve 17 and the low flowrate control valve 18. When switched on the highflame control switch 52, the mediumflame control switch 53 and the lowflame control switch 54 are simultaneously switched on to open the medium flowrate control valve 17 and the low flowrate control valve 18 for enabling a high flow rate of fuel gas to pass to the burnerflame nozzle tube 74 for burning. - As shown in FIG. 7, the
main valve assembly 12 and the ignitionflame control valve 15 are respectively connected to two terminals of theelectronic igniter 8, enabling theelectronic igniter 8 to control themain valve assembly 12 and the ignitionflame control valve 15 separately. The advantage of this design enables an additional control circuit to be added to theelectronic igniter 8 to automatically disconnect the circuit to the ignition flame control valve 15 a predetermined length of time after the presence of the burner flame, so as to further close thevalve plug 25 and extinguish the ignition flame. This design saves power and fuel gas consumption. - The alternate form shown in FIG. 8 eliminates the ignition
flame control valve 15 shown in FIG. 7, enabling fuel gas to pass from themain valve assembly 12 to thefirst gas outlet 21, thesubsidiary gas pipe 71, and then theignition flame nozzle 72 for producing the desired ignition flame. The posterior actions including the operation of the highflame control switch 52, mediumflame control switch 53, or the lowflame control switch 54 to regulate the intensity of burner flame are same as the aforesaid first embodiment of the present invention. - The alternate form shown in FIG. 9 eliminates the normal-
close valve 14 shown in FIG. 8. The operation of this alternate form is same as the embodiment shown in FIG. 8. - The embodiment shown in FIG. 10 uses a
cock 6 to substitute for theoperation unit 5 of the third embodiment (FIG. 8). Thecock 6 has agas inlet 61 and a gas outlet 62. Thegas inlet 61 is connected to fuel gas source and mounted with awire gauze filter 63. The gas outlet 62 is connected to thegas inlet 20 of thevalve seat 11. Thecock 6 closes/opens the fuel gas path, regulates the flow rate of fuel gas, and switches on/off amicro switch 65. The normal-open terminal and common terminal of themicro switch 65 are respectively connected to theelectronic igniter 8. When rotating the rotary knob (not shown) of thecock 6 and depressing the actuator 66 of themicro switch 65, the two terminals are electrically connected to turn on theelectronic igniter 8, and to further open the normal-close valves gas path 19 to theignition flame nozzle 72 via thefirst gas outlet 21, and at the same time the dischargingelectrode 82 discharges a high voltage to produce sparks and to ignite the desired ignition flame. After the presence of the desired ignition flame, thesensor 83 outputs a signal to turn off the dischargingelectrode 82 and to open the valve plugs 27 and 28 of thesolenoid valves solenoid valves flame nozzle tube 74 through thesecond gas outlet 22 and themain gas pipe 73 for producing the desired burner flame. By means of rotating the rotary knob of thecock 6, the flow rate of fuel gas is regulated. Because thecock 6 is of the known art, no further detailed description is necessary. - FIG. 11 is a simplified design obtained from the embodiment shown in FIG. 10. This embodiment eliminates the normal-
close valve 14 and thesolenoid valve 18 of the embodiment shown in FIG. 10, and thecock 6 is used with the normal-close valve 13 and thesolenoid 17 to control the operation of the gas burner. The operation principle of this embodiment is same as the embodiment shown in FIG. 10. - It is to be understood that the drawings are designed for purposes of illustration only, and are not intended for use as a definition of the limits and scope of the invention disclosed.
