Cooktop appliance burner assembly

Abstract

A cooktop appliance includes a panel, a controller, and a burner assembly.The burner assembly includes a burner disposed on the panel of the cooktop appliance, and a first control valve fluidly coupled to a second control valve. The first control valve defines an inlet and an outlet, and the second control valve defines a first inlet, a second inlet, and an outlet formed within a body of the second control valve. The outlet of the second control valve is fluidly coupled with the burner to selectively direct a flow of gas thereto. The controller is configured to adjust the second control valve.

What is claimed is: 
     
         1 . A cooktop appliance, comprising:
 a panel;   a controller; and   a burner assembly, the burner assembly comprising:
 a burner disposed on the panel of the cooktop appliance; and 
 a first control valve fluidly coupled to a second control valve, the first control valve defining an inlet, a first outlet, and a second outlet, the second control valve defining a first inlet, a second inlet, and an outlet formed within a body of the second control valve, the outlet of the second control valve fluidly coupled with the burner to selectively direct a flow of gas thereto, 
 wherein the controller is configured to adjust the second control valve. 
   
     
     
         2 . The cooktop appliance of  claim 1 , wherein the first outlet of the first control valve is fluidly coupled to a first fuel line and the second outlet is fluidly coupled to a second fuel line. 
     
     
         3 . The cooktop appliance of  claim 2 , wherein the first fuel line is fluidly coupled to the first inlet of the second control valve and the second fuel line is fluidly coupled to the second inlet of the second control valve. 
     
     
         4 . The cooktop appliance of  claim 3 , further comprising a third fuel line fluidly coupled between the outlet of the second control valve and the burner. 
     
     
         5 . The cooktop appliance of  claim 1 , wherein the first inlet of the second control valve and the outlet of the second control valve form a through passage through the body of the second control valve. 
     
     
         6 . The cooktop appliance of  claim 5 , wherein the second inlet of the second control valve is fluidly coupled to the through passage between the first inlet of the second control valve and the outlet of the second control valve within the body of the second control valve. 
     
     
         7 . The cooktop appliance of  claim 6 , wherein the second inlet of the second control valve is normally closed. 
     
     
         8 . The cooktop appliance of  claim 7 , wherein the controller is configured to adjust the second control valve by opening the second inlet of the second control valve from the normally closed position. 
     
     
         9 . The cooktop appliance of  claim 8 , wherein opening the second inlet of the second control valve from the normally closed position selectively adds fuel from the first inlet of the second control valve to fuel from the second inlet of the second control valve within the body of the second control valve. 
     
     
         10 . The cooktop appliance of  claim 1 , wherein the first control valve is coupled to a knob of the cooktop appliance, whereby the first control valve is manually operated by the knob of the appliance. 
     
     
         11 . A burner assembly in operative communication with a controller of an appliance, the burner assembly comprising:
 a burner; and   a first control valve fluidly coupled to a second control valve, the first control valve defining an inlet, a first outlet, and a second outlet, the second control valve defining a first inlet, a second inlet, and an outlet formed within a body of the second control valve, the outlet of the second control valve fluidly coupled with the burner to selectively direct a flow of gas thereto,   wherein the controller is configured to adjust the second control valve.   
     
     
         12 . The burner assembly of  claim 11 , wherein the first outlet of the first control valve is fluidly coupled to a first fuel line and the second outlet is fluidly coupled to a second fuel line. 
     
     
         13 . The burner assembly of  claim 12 , wherein the first fuel line is fluidly coupled to the first inlet of the second control valve and the second fuel line is fluidly coupled to the second inlet of the second control valve. 
     
     
         14 . The burner assembly of  claim 13 , further comprising a third fuel line fluidly coupled between the outlet of the second control valve and the burner. 
     
     
         15 . The burner assembly of  claim 11 , wherein the first inlet of the second control valve and the outlet of the second control valve form a through passage through the body of the second control valve. 
     
     
         16 . The burner assembly of  claim 15 , wherein the second inlet of the second control valve is fluidly coupled to the through passage between the first inlet of the second control valve and the outlet of the second control valve within the body of the second control valve. 
     
     
         17 . The burner assembly of  claim 16 , wherein the second inlet of the second control valve is normally closed. 
     
     
         18 . The burner assembly of  claim 17 , wherein the controller is configured to adjust the second control valve by opening the second inlet of the second control valve from the normally closed position. 
     
     
         19 . The burner assembly of  claim 18 , wherein opening the second inlet of the second control valve from the normally closed position selectively adds fuel from the first inlet of the second control valve to fuel from the second inlet of the second control valve within the body of the second control valve. 
     
     
         20 . The burner assembly of  claim 11 , wherein the first control valve is coupled to a knob of the cooktop appliance, whereby the first control valve is manually operated by the knob of the appliance.
