Abstract
An efficient heat insulating food heating chamber for a solar oven. The heating chamber includes a compartment and reflecting devices for concentrating solar radiation to elevate the temperature of the heating compartment. The heating compartment is defined by a lateral outer casing, an intermediate insulation and shock absorbing medium, and an innermost evacuated or partially evacuated glass casing. The inner most casing has a substantially angular inner wall for additional reflection of solar energy and a stepped surface for supporting transparent plates and a collection plate.
Claims5
In a solar oven including an outer casing with insulated internal walls, an opening in one end thereof and a flat collector plate within the internal walls, and means for concentrating solar energy onto said collector plate to elevate the temperature of said collector plate and the compartment within said insulated internal walls to cook food received in said compartment, the improvement comprising:
- a substantially evacuated inner casing means for insulating said compartment from said outer casing, said inner casing means including a first wall portion having a first end and a second end, said first wall portion contacting said insulated internal walls, and said outer casing means including a second wall portion connecting said first end and second end of said first wall portion to provide an evacuated chamber, whereby said inner casing means supports said collector plate on said second wall portion,
- said second wall portion is thermally isolated from said first end and said second end of said first wall portion by a thermal break material.
