Burner igniting system for gas stove

Abstract

A burner igniting system includes a pilot light disposed in a gas stove for supplying a flame to a burner, an igniting and sensing device for igniting the pilot light and for sensing a presence of flame on the pilot light, and a control device includes a circuit board, a flame signal amplifying device electrically connected to the pilot light for detecting whether a flame in the pilot light is existed or not, and a processing device (MCU n) electrically connected to the flame signal amplifying device for processing the flame signal from the flame signal amplifying device into a processed signal, and to determine whether the pilot light and the burner have been successfully ignited or not.

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 flame signal on said pilot light, and   a control device including a circuit board, a flame signal amplifying device electrically connected to said pilot light for detecting whether a flame in said pilot light is existed or not, and a processing device (MCU n) electrically connected to said flame signal amplifying device for obtaining and processing the flame signal from said flame signal amplifying device into a processed signal, and to determine that said pilot light and said burner have been successfully ignited when the processed signal is changing, and to determine that said pilot light and said burner have not been successfully ignited when the processed signal is kept constant.   
     
     
         2 . The burner igniting system as claimed in  claim 1 , wherein said processing device (MCU n) is selected from a processing unit, a processor, a thermocouple sensor, a comparator or the like.
