An improved affordable, rugged, but light-weight box-oven-type solar cooker with the ability to overcome the recognized prior art limitations, such as: difficulty in achieving cooking temperatures in morning, evening and winter; restriction in reflector adjustment; heat loss through glazier cover; the inability to produce high temperatures in a short period of time and, more importantly, the inability of heat storage to continue cooking after sundown. The cooker assembly comprises a revolutionary round or hemispherical shaped cooking chamber (16) allowing the maximum amount of sunlight to cover its inner surface, creating a higher and more even heat distribution for cooking; an unhinged reflector frame (30) is pivotally mounted by arms (38R; 38L) to the housing (10) and can adjust through a 360 DEG angle. With this unlimited mobility the sun's rays can be focused into the cooking chamber (16) substantially at any angle of the sun's position regardless of time of day, or geographic location. A glazier frame (22) accommodates at least three glaziers (28) and disallows much of the heat loss from the cooking chamber (16). A first glazier, because of its close proximity to the chamber, acts as a lid or cover and protects against further heat loss. An overhead booster reflector (44) may be added to the reflector frame. The subject assembly may be capable of heat storage utilizing a heat collecting fluid and allows cooking to continue during periods of cloud cover and even hours.
