Abstract
A compact portable apparatus for brewing hot coffee, hot tea or another hot beverage has a housing with a first chamber for a supply of liquid to be heated and a filter assembly above the chamber. A cup which can receive, for example, a quantity of hot beverage to fill two standard cups confines the lower portion of the housing when the apparatus is ready for storage but the cup is placed next to the housing and beneath an outlet for hot beverage when the apparatus is to be put to use. The cup and the lower portion of the housing define an annular chamber which receives the convolutions of an electric cable serving to connect an electric heater for liquid in the first chamber with an energy source. A carrier of the filter assembly has a chamber for reception of hot beverage before the latter flows into the cup. The filter assembly has a cover which is detachably connected to the housing to seal a space within a liquid-permeable filter element so that heated liquid which ascends from the first chamber through a riser and enters the space within the filter element is compelled to flow through the filter element and into the chamber of the carrier before it flows into the cup. The filter assembly is located at a level above the cup regardless of whether the cup receives the lower portion of the housing or collects the freshly brewed beverage.
