Abstract

Abstract An extract generator for producing either hot or cold beverages. A movable stand for maintaining the temperature of a hot beverage is placed in a first position below a hot water unit. Hot water from the unit passes through a filter device, in which it picks up the extract, to a jug, in which the extract accumulates. To generate cold beverages a cooling vessel is placed between the filter device and jug and the movable stand is moved to a second position so that the filtering device, cooling vessel and jug may be placed below the hot water unit but not on the movable stand.
