Apparatus for controlling an electrical cooker and related method thereof

Abstract

The present invention provides a micro-control device, which comprises a RC oscillator for generating a reference clock, a plurality of analog switches coupled to the touch switches for controlling transmission of the transition signal and a plurality of counters for counting time, all of the counters stop counting when one of the counters overflows and content of all counters being read, wherein ON/OFF of the analog switches controlled by a software.

1 . An apparatus for controlling an electrical cooker, comprising:
 at least one touch switch for generating a transition signal;   a panel control unit coupled to the least one touch switch for processing and detecting states of the touch switch to generate an electric signal; and   a micro-control unit coupled to the panel control unit for receiving the electric signal transmitted by the panel control unit and controlling power the electrical cooker.   
     
     
         2 . The apparatus as claimed in  claim 1 , further comprising a light-emitting circuit controlled by the micro-control unit. 
     
     
         3 . The apparatus as claimed in  claim 2 , wherein the light-emitting circuit comprises a light-emitting diode and a resister which restricts current. 
     
     
         4 . The apparatus as claimed in  claim 1 , wherein the panel controller further comprises a IC circuit, which comprises:
 a RC oscillator for generating a reference clock;   a plurality of analog switches for controlling transmission of the transition signal; and   a plurality of counters for counting time, all of the counters stop counting when one of the counters overflows and content of all counters being read; wherein ON/OFF of the analog switches controlled by a software.   
     
     
         5 . The apparatus as claimed in  claim 4 , wherein the IC circuit further comprises three pins IN, RREF and CREF, coupled to resister and capacitance for changing the frequency of the RC oscillator. 
     
     
         6 . An apparatus for controlling an electrical cooker, comprising:
 a plurality of touch switches coupled to the least one touch switch for generating a transition signal indicating one of the touch switches being touched by human beings;   a panel control unit, coupled to the touch switches and including a IC circuit for processing and detecting states of the touch switch to generate an electronic signal, wherein the IC circuit comprises:   a RC oscillator for generating a reference clock;   a plurality of analog switches for controlling transmission of the transition signal; and   a plurality of counters for counting time, all of the counters stop counting when one of the counters overflows and content of all counters being read; wherein ON/OFF of the analog switches controlled by a software; and   a micro-control unit coupled to the panel control unit for receiving the electric signal transmitted by the panel control unit and controlling power the electrical cooker.
