Abstract
An oven device (4) is adapted for use with a source of heat (24), such as a camp stove, and a cooking utensil (6), such as a covered (12) pot or pan (8), positioned over and separated from the heat source by a heat shield (20). The oven device includes a high temperature flexible, foldable convection dome, such as one made of aluminized fiberglass, having a vertically oriented sidewall (34) and a top (36). The top has a central vent opening (40). The convection dome is supported on the lid covering the pan by a number of radially extending pockets (42). The material from which the convention dome is made of is flexible enough to permit the convection dome to be folded up into a compact rectangular configuration but stiff enough to allow the pockets to support the convection dome above the lid of the pan with the sidewalls of the convection dome spaced apart from the sides of the pan. This provides a convection path up past the sidewalls of the pan and radially inwardly over the lid and then out through the vent opening convection dome. The temperature of the air passing through the vent opening is monitored by a thermometer (18) incorporated into a handle (14) on the lid.
