Abstract
A beverage making appliance operable automatically or manually, and also providing a hot water faucet. The appliance has a cold water basin located over a hot water tank with a cold water tube extending down into the hot water tank from a basin drain opening whereby cold water discharges into the lower portion of the hot water tank and displaces hot water either through a faucet, or a spray head onto the contents of a brew funnel. When operated in its automatic mode, cold water is delivered to the basin through a conduit connected with a supply of cold water under pressure. The conduit has both flow control and solenoid valves whereby a predetermined volume of cold water is delivered on each actuation of a timer. A level control circuit, together with a water level sensing probe disposed within the hot water tank, also actuates the solenoid valve to maintain a predetermined water level in the tank as hot water is drawn through the faucet. Additional circuitry, including a relay, disables the level control circuit on actuation of the timer. The relay, through a set of normally closed contacts, electrically connects the level control circuitry with the solenoid valve. The timer is connected to the solenoid valve through a second set of normally open relay contacts. When the appliance is operated in the automatic mode, the relay disconnects the level control circuitry, allowing the timer to control the solenoid valve.
