ABSTRACT:
A domestic pressure cooking appliance includes a heat exchanger connected to means for regulating flow of a liquid phase thermal exchange fluid which is heated and cooled by thermal sources separate from the pressure cooker. For cleaning and handling convenience, food is first placed in a removable food container. In order to enhance exchange of heat with the food or its container, one embodiment of the pressure cooker uses forced air convection and another embodiment uses latent heat of water vaporization from a wick covering the food container.
The pressure cooking appliances in their several embodiments are part of a system of domestic appliances wherein a plurality of various appliances connect to mains containing the thermal exchange fluid which is forced to circulate under control of selector and regulator valves between the appliances and thermal reservoirs at hot, cold, and moderate temperatures.
