Abstract: A dual-voltage, energy saving, electric pressure cooker is designed with a thermally insulated cooking pot, spaced-apart support on the bottom of the pot to prevent food from sticking to the bottom, a unique, hinged, sauce-pan style handle for sealing and unsealing the pot using one hand, a built-in modem that supports the remote operation of manual or preprogrammed cooking controls by telephone or computer. The energy saving is accomplished in a two-mode pressure cooking process. Cooking mode one is active heating or steaming for a short, but controlled period of time, as the liquid inside the pot reaches a temperature of approximately 120° C. (250° F.). Heating is then discontinued and foodstuffs are subsequently cooked to perfection in a second cooking mode wherein latent heat from the first cooking mode completes the cooking process without additional heat being added.

Abstract: A vacuum coffee maker has a starved electric heating arrangement having a solid body providing a reservoir. The chamber is covered by a circular lid that prevents flow of steam directly vertically up a tube from the chamber. At the end of a normal heating cycle, the temperature of the body rises rapidly and power supplied to a heating element is automatically turned off under the control of a thermostat. The heating arrangement is used without alteration (e.g. to the setting of the thermostat) to keep-warm hot coffee in a lower container after the end of the normal heating coffee-making cycle. The effect of having the lid is that during a keep-warm function, the reservoir is generally starved of liquid because any liquid entering the reservoir is immediately evaporated and this restricts flow of more liquid into the reservoir and hence starves the reservoir.
