Burner igniting system for gas stove

Abstract

A burner igniting system includes a burner disposed in a gas stove, a pilot light disposed in the gas stove for supplying a flame to the burner, an igniting and sensing device disposed in the gas stove for igniting the pilot light and for sensing a presence of flame on the pilot light, and a control device includes two or more processing devices (MCU 1-n), a high voltage circuit electrically connected the processing devices (MCU 1-n) for being actuated by the processing devices (MCU 1-n), and the processing devices (MCU 1-n) and the high voltage circuit are electrically connected to the igniting and sensing device for actuating the igniting and sensing device to selectively ignite the burner with the pilot light.

I claim: 
     
         1 . A burner igniting system comprising:
 a base plate disposed in a gas stove,   a burner disposed in said gas stove,   a pilot light disposed on said base plate for supplying a flame to said burner,   an igniting and sensing device disposed on said base plate for igniting said pilot light and for sensing a presence of flame on said pilot light, and   a control device including a first processing device (MCU 1), a second processing device (MCU 2), at least one third processing device (MCU n), a high voltage circuit electrically connected said first and said second and said at least one third processing devices (MCU 1-n) for being actuated and operated by said first and said second and said at least one third processing devices (MCU 1-n), and said first and said second and said at least one third processing devices (MCU 1-n) and said high voltage circuit being electrically connected to said igniting and sensing device for actuating said igniting and sensing device to selectively ignite said burner with said pilot light.   
     
     
         2 . The burner igniting system as claimed in  claim 1 , wherein said control device includes a voltage sensing circuit electrically connected to said high voltage circuit for sensing a voltage in said control device. 
     
     
         3 . The burner igniting system as claimed in  claim 2 , wherein said control device includes a comparator electrically connected to said voltage sensing circuit and said high voltage circuit for sending a compared signal to said processing devices. 
     
     
         4 . The burner igniting system as claimed in  claim 1 , wherein said control device includes an ignition detecting circuit electrically connected to said first and said second and said at least one third processing devices (MCU 1-n) for detecting whether said burner has been ignited or not. 
     
     
         5 . The burner igniting system as claimed in  claim 4 , wherein said control device includes a timer electrically connected to said high voltage circuit and said ignition detecting circuit and said first and said second and said at least one third processing devices (MCU 1-n) for determining a time period that said burner has not been successfully ignited. 
     
     
         6 . The burner igniting system as claimed in  claim 4 , wherein said ignition detecting circuit is selected from a trigger diode.
