ABSTRACT:
A machine for making coffee, soup or other hot beverages has a housing for a pressure-resistant container which can receive a supply of water or another liquid. The bottom wall of the container constitutes or supports an insulating carrier for one or more thick film conductors which can be connected by several relays so as to cause heated liquid to flow to the holder in pulsating fashion. One of the relays receives signals from a thermometer which monitors the temperature of heated liquid in the conduit. A second heater employing one or more thick film conductors is used to heat a warming plate for a vessel which can be placed onto a leg of the housing beneath the holder to receive hot beverage when the outlet of the holder is open. The conduit includes a riser with an inlet at its lower end, and a pipe connecting the upper end of the riser with an outlet for heated liquid. The riser is rotatably relative to and/or is movable up and down in the container so as to facilitate admission of heated liquid into a vessel for the making of soup and/or to select the quantity of heated liquid which is to be transferred from the container into the holder.
