Baking system for a gas cooking appliance

Abstract

A gas cooking appliance including a gas oven cavity for baking a food item, the gas oven cavity including a top surface and a bottom surface, a first heat source disposed adjacent the bottom surface of the gas oven cavity, a second heat source disposed adjacent the top surface of the gas oven cavity, and a controller configured to cycle the first heat source and the second heat source for providing heat above and below the food item during baking

1 . A gas cooking appliance comprising:
 a gas oven cavity for baking an food item, the gas oven cavity including a top surface and a bottom surface;   a first heat source disposed adjacent the bottom surface of the gas oven cavity;   a second heat source disposed adjacent the top surface of the gas oven cavity; and   a controller configured to cycle the first heat source and the second heat source for providing heat above and below the food item during baking.   
     
     
         2 . The gas cooking appliance of  claim 1 , wherein at least one of the first heat source and second heat source comprises a gas burner. 
     
     
         3 . The gas cooking appliance of  claim 1 , wherein the second heat source comprises at least one of a gas burner, or an electric heating element. 
     
     
         4 . The gas cooking appliance of  claim 1 , wherein the controller is configured to cycle the first heat source and the second heat source such that between activation of one of the first heat source and the second heat source, the first heat source and the second heat source are off for a predetermined period of time. 
     
     
         5 . The gas cooking appliance of  claim 4 , wherein the predetermined period of time is selected to allow for sufficient fuel pressure for activation of that one of the first heat source and second heat source that is to be activated. 
     
     
         6 . The gas cooking appliance of  claim 4 , wherein the predetermined period of time is selected to allow for substantially complete combustion of fuel by that one of the first heat source and second heat source that has been deactivated. 
     
     
         7 . A system for cycling a first heat source and a second heat source during a bake cycle of a gas cooking appliance, the gas cooking appliance having a gas oven cavity and the first heat source and the second heat source are disposed inside the gas oven cavity, the system comprising:
 a controller configured to cycle the first heat source and the second heat source for providing heat above and below a food item placed within the gas cooking appliance; and   the gas oven cavity includes a top surface and a bottom surface, the first heat source being disposed adjacent the bottom surface and the second heat source being disposed adjacent the top surface.   
     
     
         8 . The system of  claim 7 , wherein the controller comprises a memory, the memory including selectable parameters for specifying the cycling of the first heat source and the second heat source. 
     
     
         9 . The system of  claim 7 , wherein at least one of the first heat source and the second heat source comprises a gas burner. 
     
     
         10 . The system of  claim 7 , wherein the second heat source comprises at least one of a gas burner, and an electric heating element. 
     
     
         11 . The system of  claim 7 , wherein the controller is configured to cycle the first heat source and the second heat source such that between activation of one of the first heat source and the second heat source, the first heat source and second heat source are off for a predetermined period of time. 
     
     
         12 . The system of  claim 11 , wherein the predetermined period of time is selected to allow sufficient fuel pressure for activation of that one of the first heat source and second heat source that is to be activated. 
     
     
         13 . The system of  claim 11 , wherein the predetermined period of time is selected to allow for substantially complete combustion of fuel by that one of the first heat source and second heat source that has been deactivated. 
     
     
         14 . A method for cycling a first heat source and second heat source of a gas cooking appliance during baking, where the gas cooking appliance includes a controller and a gas oven cavity having a top surface and a bottom surface, the first heat source being disposed adjacent the bottom surface and the second heat source being disposed adjacent the top surface, the method comprising:
 activating one of the first heat source and the second heat source with the controller;   activating the other of the first heat source and the second heat source with the controller; and   between activation of the one of the first heat source and the second heat source and activation of the other of the first heat source and the second heat source, deactivating both of the first heat source and the second heat source with the controller for a predetermined period of time,   wherein at least one of the first heat source and the second heat source comprises a gas burner.   
     
     
         15 . The method of  claim 14 , wherein the second heat source comprises at least one of a gas burner or an electric heating element. 
     
     
         16 . The method of  claim 14 , wherein the predetermined period of time is selected to allow sufficient fuel pressure for activation of that one of the first heat source and the second heat source that is to be activated. 
     
     
         17 . The method of  claim 14 , wherein the predetermined period of time is selected to allow for substantially complete combustion of fuel by that one of the first heat source and the second heat source that has been deactivated.
