ABSTRACT:
An electrically heated pot for heating the keeping warm a liquid includes a vacuum container having a vacuum region formed between the outer surface of a cylindrical internal tank and the inner surface of an external tank. The internal tank has an opening at one end. A cylindrical reservoir tank for accomodating the liquid to be heated is removably located within the internal tank through the opening. The central portion of the reservoir tank is in close contact with the inner surface of the internal tank, while an end portion thereof opposite the opening is shaped to define with the internal tank a heater mounting room. A thermostatically controlled electric heater is mounted on the surface of the reservoir tank in the heater mounting room and is removable with the reservoir tank through the opening. A power supply wire connected to the heater is led to the outside of the vacuum container along the length of the reservoir tank to the outside of the container through the opening through a guide groove formed in either the inner surface of the internal tank or the outer surface of the reservoir tank or through a guide pipe passing through the reservoir tank. A handle frame removably holds the vacuum container and has a pivoted lid for closing the opening and a bellows pump is provided on the lid for pressurizing the reservoir tank for discharging heated liquid.
