Cooktop appliance with a thermally isolated injet

Abstract

A cooktop appliance includes a top panel that defines a hole. A gas burner includes a burner body that defines a plurality of flame ports. A receptacle is mounted to the top panel at the hole of the top panel. The burner body is positioned on the receptacle. An injet is mounted to the top panel such that the injet is positioned opposite the burner body about the top panel. A fuel orifice is positioned on the injet. The fuel orifice is oriented for directing a flow of fuel to the burner body. The burner body is positioned such that the burner body does not contact the injet.

What is claimed is: 
     
         1 . A cooktop appliance, comprising:
 a top panel defining a hole; and   a gas burner comprising
 a burner body defining a plurality of flame ports, 
 a receptacle mounted to the top panel at the hole of the top panel, the burner body positioned on the receptacle, 
 an injet mounted to the top panel such that the injet is positioned opposite the burner body about the top panel, and 
 a fuel orifice positioned on the injet, the fuel orifice oriented for directing a flow of fuel to the burner body; 
 wherein the burner body is positioned such that the burner body does not contact the injet. 
   
     
     
         2 . The cooktop appliance of  claim 1 , wherein the burner body does not contact the injet to prevent direct conductive heat transfer from the burner body to the injet. 
     
     
         3 . The cooktop appliance of  claim 1 , wherein the gas burner further comprises a clip that extends between the receptacle and the injet to electrically couple the receptacle to the injet. 
     
     
         4 . The cooktop appliance of  claim 3 , wherein the injet is grounded. 
     
     
         5 . The cooktop appliance of  claim 1 , wherein the burner body is positioned on the receptacle such that the burner body is suspended over the top panel on the receptacle. 
     
     
         6 . The cooktop appliance of  claim 1 , wherein the gas burner further comprises an inlet conduit extending downwardly from the burner body through the hole, the fuel orifice oriented for directing the flow of fuel into the inlet conduit. 
     
     
         7 . The cooktop appliance of  claim 1 , wherein an outer perimeter of the receptacle is shaped complementary to an edge of the top panel at the hole. 
     
     
         8 . The cooktop appliance of  claim 1 , further comprising a pneumatically actuated gas valve positioned on the injet. 
     
     
         9 . The cooktop appliance of  claim 8 , wherein the pneumatically actuated gas valve comprises:
 a diaphragm positioned between an air passage and a gas passage within the injet;   a seal mounted to the injet within the gas passage; and   a plug mounted to the diaphragm, the plug positioned against the seal in a closed configuration of the pneumatically actuated gas valve.   
     
     
         10 . The gas burner of  claim 1 , wherein the fuel orifice is removable from the injet. 
     
     
         11 . The gas burner of  claim 1 , wherein the fuel orifice is positioned directly below the burner body. 
     
     
         12 . A cooktop appliance, comprising:
 a top panel defining a hole; and   a gas burner comprising
 a burner body defining a plurality of flame ports, 
 a receptacle mounted to the top panel at the hole of the top panel, the burner body positioned on the receptacle, 
 an injet mounted to the top panel such that the injet is positioned opposite the burner body about the top panel, 
 an inlet conduit extending downwardly from the burner body through the receptacle and the hole, and 
 a fuel orifice positioned on the injet, the fuel orifice oriented for directing a flow of fuel to into the inlet conduit, 
 wherein the burner body is positioned such that the burner body does not contact the injet. 
   
     
     
         13 . The cooktop appliance of  claim 12 , wherein the burner body does not contact the injet to prevent direct conductive heat transfer from the burner body to the injet. 
     
     
         14 . The cooktop appliance of  claim 12 , wherein the gas burner further comprises a clip that extends between the receptacle and the injet to electrically couple the receptacle to the injet. 
     
     
         15 . The cooktop appliance of  claim 14 , wherein the injet is grounded. 
     
     
         16 . The cooktop appliance of  claim 12 , wherein the burner body is positioned on the receptacle such that the burner body is suspended over the top panel on the receptacle. 
     
     
         17 . The cooktop appliance of  claim 12 , wherein an outer perimeter of the receptacle is shaped complementary to an edge of the top panel at the hole. 
     
     
         18 . The cooktop appliance of  claim 12 , further comprising a pneumatically actuated gas valve positioned on the injet. 
     
     
         19 . The cooktop appliance of  claim 18 , wherein the pneumatically actuated gas valve comprises:
 a diaphragm positioned between an air passage and a gas passage within the injet;   a seal mounted to the injet within the gas passage; and   a plug mounted to the diaphragm, the plug positioned against the seal in a closed configuration of the pneumatically actuated gas valve.   
     
     
         20 . The gas burner of  claim 12 , wherein the fuel orifice is removable from the injet, and the fuel orifice is positioned directly below the burner body.
