Ignition device for a gas stove

Abstract

An ignition device is mounted in a stove base of a gas stove and has a gas valve assembly, an electronic igniter and a triggering knob. The gas valve assembly is mounted in the stove base and has a gas valve with a valve nozzle and an extending tube extending toward multiple elongated burners mounted in the stove base and having multiple gas holes formed through the extending tube at intervals. When the triggering knob is pressed and turned, gas is simultaneously ejected from the gas holes and mixes with gas simultaneously ejected the burners to form a continuous gas cloud, and the electronic igniter simultaneously produces sparkles to ignite gas discharged from the valve nozzle to generate a starting flame tongue instantly extending toward and igniting the gas cloud to ignite all the burners to effectively reduce leakage of gas.

1 . An ignition device for a gas stove having a stove base with a burner chamber formed in the stove base and having an inner surface, the ignition device comprising
 a gas valve assembly being adapted to be mounted in the stove base and having
 a gas valve having
 a distal end; 
 an inlet; 
 an outlet; 
 a mounting hole; and 
 a valve nozzle being formed on and protruding from the distal end of the gas valve to form a discharge path and spraying gas; 
 
 an inlet tube being connected to the inlet of the gas valve; and
 an extending tube being adapted to be mounted on the inner surface of the burner chamber, being connected to the mounting hole of the gas valve, communicating with and receiving gas from the gas valve and having 
 multiple gas holes being formed through the extending tube at intervals; 
 
   an electronic igniter being mounted near the valve nozzle and having an electrode extending into the discharge path of the valve nozzle;
 a flame restrictor being mounted near the electrode of the electronic igniter partially around the discharge path of the valve nozzle; and 
 a triggering knob being adapted to be mounted on the stove base, being connected electrically to the electronic igniter and being connected to and operating the gas valve to selectively open and close the gas valve. 
   
   
   
       2 . A gas stove comprising
 a stove base having
 a burner chamber being formed in the stove base and having an inner surface; 
   multiple elongated burners being mounted in the burner chamber in the stove base at intervals, and each elongated burner having two opposite narrow ends and a gas inlet;   an outlet tube being mounted in the burner chamber and having
 an outer surface; and 
 multiple gas nozzles being mounted in the outer surface of the outlet tube and aligning respectively with the gas inlets of the elongated burners; and 
   an ignition device being mounted in the stove base and having
 a gas valve assembly being mounted in the stove base adjacent to the elongated burners and having
 a gas valve having
 a distal end; 
 an inlet; 
 an outlet being connected to the outlet tube; 
 a mounting hole; and 
 a valve nozzle being formed on and protruding from the distal end of the gas valve, extending toward the elongated burners perpendicularly to the elongated burners to form a discharge path and spray gas toward the elongated burners; 
 
 an inlet tube being connected to the inlet of the gas valve; and 
 an extending tube being mounted on the inner surface of the burner chamber in the stove base, connected to the mounting hole of the gas valve, communicating with and receiving gas from the gas valve, extending perpendicularly to the elongated burners adjacent to one of the narrow ends of the elongated burners and having
 a rear section; and 
 multiple gas holes being formed through the extending tube at intervals shorter than that between adjacent elongated burners; 
 
 
 an electronic igniter being mounted near the valve nozzle and having
 an electrode extending into the discharge path of the valve nozzle; 
 
 a flame restrictor being mounted near the electrode of the electronic igniter partially around the discharge path of the valve nozzle; and 
 a triggering knob being mounted on the stove base, connected electrically to the electronic igniter and connected to and operating the gas valve to selectively open and close the gas valve. 
   
   
   
       3 . The gas stove as claimed in  claim 2 , wherein the gas holes are formed within the rear section of the extending tube and are away from an elongated burner closest to the gas valve.
