    • BRIEF DESCRIPTION OF THE DRAWINGS
  • FIG. 1 is a block diagram illustrating a control circuit of a gas appliance in accordance with the present invention.
    •  DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
  • Referring to FIG. 1, a gas appliance in accordance with the present invention comprises an igniting device 10 actuatable or operatable by the users to selectively ignite a pilot burner 11 which may then be used to ignite one or more main stove heads or main burners 12 for burning. A solenoid valve 13 may be provided and coupled to the pilot burner 11 and/or the main burners 12 for controlling the gas supply to either or both of the pilot burner 11 and the main burners 12. A control circuit 14 is coupled to the igniting device 10 and coupled to the solenoid valve 13 for controlling or actuating the solenoid valve 13 to operate the pilot burner 11 and/or the main burners 12. A switch 15 may be provided and coupled to the control circuit 14 for being actuated or operated by the users to issue an initiating or initializing signal in order to actuate or operate the control circuit 14 and thus to control or actuate the solenoid valve 13 to operate the pilot burner 11 and/or the main burners 12.
  • A signal receiving device or remote device 16 may further or optionally be provided and coupled to the control circuit 14 for initializing or actuating or operating the control circuit 14 remotely. For example, a remote control device or remote signal issuing device may be operated or actuated by the users, and the signal receiving device or remote device 16 may receive the remote signals, such as the audio signals which may be amplified, rectified and/or decoded to actuating or operating the control circuit 14 remotely. A detecting device 20, such as a detecting circuit 20, a detecting probe 20 or the like may further be provided and coupled to the control circuit 14 and/or to the solenoid valve 13 and/or to the pilot burner 11 and/or the main burners 12 and/or disposed beside the pilot burner 11 and/or the main burners 12 for detecting whether the pilot burner 11 and/or the main burners 12 is working or not or for detecting whether a flame has been generated by the pilot burner 11 and/or the main burners 12 or not.
  • For example, the detecting device 20 or the detecting circuit 20 or the detecting probe 20 may be used for detecting the absence of the flame or for detecting the temperature of the flame or the like and may send the detected signal, such as the detected temperature signal of the flame to the control circuit 14 which may compare the detected signal or the detected temperature signal with a presetting or predetermined high value, such as a presetting or predetermined high temperature value and/or a presetting or predetermined low value, such as a presetting or predetermined low temperature value in order to determine whether the temperature of the flame or of the main burners 12 or of the pilot burner 11 is over or below the predetermined high or low value. When the detected signal is higher or lower than the presetting or predetermined high or low value, the control circuit 14 may control or actuate the solenoid valve 13 to shut-off or to switch off the pilot burner 11 and/or the main burners 12.
  • A switching or converting or changing circuit or device 30 may be provided and coupled to the control circuit 14, and one or more batteries 31 are coupled to the changing device 30 or directly coupled to the control circuit 14 for supplying the electric energy or electric source to energize the control circuit 14 and/or the solenoid valve 13 and/or the detecting device 20 and/or the igniting device 10. A thermo-couple 32 may be provided and directly coupled to the changing device 30 or indirectly coupled to the changing device 30 via a supercharging circuit or device 33 or directly coupled to the control circuit 14, and the thermo-couple 32 may be disposed beside the pilot burner 11 and/or the main burners 12 for allowing the thermo-couple 32 to be actuated by the flame generated by the pilot burner 11 and/or the main burners 12 in order to selectively supply the electric energy or electric source to energize the control circuit 14 and/or the solenoid valve 13 and/or the detecting device 20 and/or the igniting device 10.
  • For example, when the pilot burner 11 and/or the main burners 12 is working or generating the flame, the thermo-couple 32 may be heated or actuated by the flame to generate a voltage or an electric energy or electric source which may be supercharged or boosted by the supercharging circuit or device 33, and the thermo-couple 32 may thus be used to energize the control circuit 14 and/or the solenoid valve 13 and/or the detecting device 20 and/or the igniting device 10 when the pilot burner 11 and/or the main burners 12 is working or generating the flame, such that the control circuit 14 and/or the solenoid valve 13 and/or the detecting device 20 and/or the igniting device 10 may still be operated or actuated by the thermo-couple 32 even when the batteries 31 are out of electricity. The changing device 30 may automatically switch between the thermo-couple 32 and the batteries 31 when the batteries 31 are out of electricity.
  • In operation, the control circuit 14 may be operated or actuated by the switch 15 or the remote device 16 in order to actuate or operate the igniting device 10 which may be used to selectively ignite the pilot burner 11, and the pilot burner 11 in turn may be used to ignite the main stove heads or main burners 12. At this moment, the control circuit 14 may be energized by the batteries 3 1, and the igniting device 10 may not be used to ignite the pilot burner 11 when the batteries 31 are out of electricity. When the pilot burner 11 and/or the main burners 12 is working or generating the flame, the thermo-couple 32 may be actuated to generate the electric energy or electric source and may thus be selectively used to energize the control circuit 14 and/or the solenoid valve 13 and/or the detecting device 20 and/or the igniting device 10 by the changing device 30.
  • It is to be noted that the thermo-couple 32 may generate and supply the electric energy or electric source to selectively energize the control circuit 14 and/or the solenoid valve 13 and/or the detecting device 20 and/or the igniting device 10 such that the batteries 31 may be economized and may be used longer, and the thermo-couple 32 may still be used to selectively energize the control circuit 14 and/or the solenoid valve 13 and/or the detecting device 20 and/or the igniting device 10 even when the batteries 31 are out of electricity such that the pilot burner 11 and/or the main burners 12 may still be switched off when the batteries 31 are out of electricity or when an emergency circumstance or condition is occurred.
  • The devices or elements 10-15, 20 and 30-33 have been fully disclosed in a co-pending patent application without the remote device 16, and the remote device 16 is separately disclosed and claimed in the present invention.
  • Accordingly, the gas appliance in accordance with the present invention includes a safety or security device for automatically shut-off the fire or flame in responsive to flame outage, and/or when the energizing battery is out of electricity.
  • Although this invention has been described with a certain degree of particularity, it is to be understood that the present disclosure has been made by way of example only and that numerous changes in the detailed construction and the combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as hereinafter claimed.
