Apparatus to control gas burner for stir-fry cooking

Abstract

An apparatus and system for controlling gas burner, either by knee or by hand, to achieve a desirable timing and volume of heat during the process of Chinese stir-fry cooking.

1 . An apparatus, for controlling gas in a gas burner used for stir-fry cooking to achieve a desirable timing and volume of heat, is operated either manually by hand or automatically through magnets.  
   
   
       2 . An apparatus in  claim 1 , comprising: 
 a magnetic control unit, which comprises at least a magnetic object, a sensor board, a relay and an electromagnetic valve;    a hand control unit, which comprises at least a handle and a hand control valve;    a valve box, which harbors the said electromagnetic valve, the said hand control valve and a gas passing channel.    
   
   
       3 . The said magnetic object in  claim 2 , comprises at least one magnet.  
   
   
       4 . The said sensor board in  claim 2 , comprises at least one magnetic detecting device.  
   
   
       5 . The said magnetic detecting device in  claim 4 , comprises at least one reed switch.  
   
   
       6 . A method to use the said apparatus in  claim 1  in stir-fry cooking, comprises: 
 turning on the device power;    a person wearing the said magnetic band on his knee;    placing the said magnetic band close to the said sensor board, which trigger the said reed switch and turn on the said relay, as a result, the said electromagnetic valve is open to allow gas to flow to a gas burner;    moving the said magnetic band away from the said sensor board, which release the said reed switch and turn off the said relay, as a result the said electromagnetic valve is close to block gas flowing to a gas burner;    alternatively turning the said handle to open/close the said hand control valve to allow/block gas to flow to a gas burner, respectively.    
   
   
       7 . A stir-fry cooking system, comprising at least one apparatus in  claim 1.
