Broiler for cooking appliances
A broiler assembly for a cooking appliance, the cooking appliance having an oven cavity and the broiler assembly is disposed within the oven cavity. The broiler assembly includes a reflector having first and second sides, side retainers coupled to a respective one of the first and second sides, and at least one carbon emitter heating element mounted to the side retainers. The at least one carbon emitter heating element includes a carbon filament disposed within a lamp.
1. A broiler assembly for a cooking appliance, the cooking appliance haying an oven cavity with the broiler assembly being disposed within the oven cavity, the broiler assembly comprising:
a reflector having first and second sides;
side retainers coupled to a respective one of the first and second sides;
a plurality of carbon emitter heating elements mounted to the side retainers the carbon emitter heating elements collectively developing a substantially constant heat flux intensity within the oven cavity; and
a controller connected to the plurality of carbon emitter heating elements and operative to individually cycle the plurality of carbon emitter heating elements to produce the substantially constant heat flux intensity within the oven cavity.
2. The broiler assembly of claim 1 , wherein each carbon emitter heating element comprises a substantially flat carbon filament.
3. The broiler assembly of claim 1 , wherein each carbon emitter heating element comprises a quartz or fused silica transparent lamp having a carbon filament disposed in the lamp.
4. The broiler assembly of claim 3 , wherein the side retainers comprise a first side retainer and a second side retainer, each of the first and second side retainers comprising at least one aperture configured to receive at least part of the plurality of carbon emitter heating elements.
5. The broiler assembly of claim 4 , wherein the lamp comprises a first end, a second end and a first insulator disposed on the first end, the first and second ends extending laterally between the first and second side retainers, the first insulator being configured to engage the at least one aperture of the first side retainer such that the first insulator is substantially fixed laterally relative to the first side retainer.
6. The broiler assembly of claim 5 , wherein the lamp further comprises a second insulator disposed on the second end, the second insulator being configured to engage the at least one aperture of the second side retainer such that the second insulator is free to move laterally relative to the second side retainer.
7. The broiler assembly of claim 1 , wherein the cooking appliance comprises a rack disposed within the oven cavity, the rack configured to be located at variable positions within the oven cavity relative to a location of the broiler assembly, and wherein the heat flux intensity developed by the carbon emitter heating elements is substantially constant for each position of the rack within the oven cavity.
8. A cooking appliance comprising:
a frame forming an oven cavity; and
a broiler assembly disposed within the oven cavity, the broiler assembly comprising:
a reflector having first and second sides;
side retainers coupled to a respective one of the first and second sides;
a plurality of carbon emitter heating elements mounted to the side retainers, the carbon emitter heating elements collectively developing a substantially constant heat flux intensity within the oven cavity; and
a controller connected to the plurality of carbon emitter heating elements and operative to individually cycle the plurality of carbon emitter heating elements to produce the substantially constant heat flux intensity within the oven cavity.
9. The cooking appliance of claim 8 , wherein each carbon emitter heating element comprises a substantially flat carbon filament disposed in a glass tube.
10. The cooking appliance of claim 9 , wherein the glass tube comprises a quartz or fused silica transparent lamp.
11. The cooking appliance of claim 10 , wherein the side retainers include a first and second side retainer, each of the first and second side retainers including at least one aperture configured to receive at least part of the plurality of carbon emitter heating elements.
12. The cooking appliance of claim 11 , wherein the lamp comprises a first end, a second end and a first insulator disposed on the first end, the first and second ends extending laterally between the first and second side retainers, the first insulator being configured to engage the at least one aperture of the first side retainer such that the first insulator is substantially fixed laterally relative to the first side retainer.
13. The cooking appliance of claim 12 , wherein the lamp further comprises a second insulator disposed on the second end, the second insulator being configured to engage the at least one aperture of the second side retainer such that the second insulator is free to move laterally relative to the second side retainer.
14. The cooking appliance of claim 8 , wherein the cooking appliance comprises a rack disposed within the oven cavity, the rack configured to be located at variable positions within the oven cavity relative to a location of the broiler assembly, and wherein a heat flux intensity developed by the carbon emitter heating elements is substantially constant for each position of the rack within the oven cavity.
15. The cooking appliance of claim 14 , wherein the heat flux intensity remains substantially constant at increasing vertical distances of the rack from the broiler assembly.
