Abstract
An apparatus for preparing infusions such as any of several forms of the beverage coffee can be constructed so as to include an enclosed container in which water is adapted to be heated so as to be utilized either as hot water or as steam. An electric heating element is associated with the container for heating the contents of the container. A bottom outlet from the container is adapted to convey hot water and is connected to a line or conduit to the inlet of an infuser or brewing basket, the outlet of which is adapted to convey a complete beverage or infusion to an appropriate container. A top outlet from the container is adapted to convey steam from the container through an appropriate conduit or line containing at least one valve to another container where such steam may be used in preparing a beverage such as cappuccino or may be employed for generalized heating purposes. Different pressure responsive switches are connected in a circuit for operating the heating element for use in regulating the temperature of hot water supplied to the infuser and for use in regulating the temperature of the steam supplied from the container.
