摘要： A cooking utensil (20) with improved heat retention includes an inner pot (30) within an outer pot (32) and separated in a closely spaced-apart relationship forming a chamber (34) therebetween. The chamber (34) is evacuated and sealed at the upper edges of the pots (30, 32). The vacuum along with the minimum of thermal contact between the inner and outer pots, and the reduced radiative heat transfer due to low emissivity coatings (57, 58) on the pots (30, 32), provide for a highly insulated cooking utensil (20). Any combination of mechanisms (36) for selectively disabling and re-enabling the insulating properties of the pots (30, 32) are provided within the chamber (34). These mechanisms (36) may include: a hydrogen gas producing and re-absorbing device (250), adjustable metal contacts (166) or selectable bimetallic switches (230) can be used to bridge the gap between the pots (30, 32). Additionally, phase change materials (206) may be provided within the cooking utensil (20). Further, microprocessor (236) and associated hardware can be provided for automatically controlling the mechanisms (36).
