ABSTRACT:
A beverage making appliance operable either automatically or as a pour-in beverage maker. A cold water basin is located over a hot water tank. Cold water tube extends down into the hot water tank from a drain opening in the bottom of the basin whereby cold water discharges into the lower portion of the hot water tank and displaces an equal quantity of hot water through a siphon tube for discharge through a spray head onto the contents in a brew funnel positioned beneath the spray head. In the automatic mode, cold water is delivered to the cold water basin through a cold water conduit connected with a supply of cold water under pressure. The cold water conduit has a flow control valve and a timer-controlled solenoid valve whereby a predetermined volume of cold water may be repetitively delivered on each actuation of the timer. The discharge end of the cold water conduit is pointed downwardly directly into the drain opening in the basin and upper end of the cold water tube. In normal operation, there is no accumulation of cold water in the cold water basin. The discharge end of the cold water conduit is spaced above the drain opening and upper end of the cold water tube so as to provide an air gap between the discharge end and the drain opening and upper end of the cold water tube which prevents siphoning of water back through the cold water conduit.
