ABSTRACT:
A beverage brewer includes a water reservoir in which water is heated to a predetermined brewing temperature by a resistance heater element within the reservoir. To initiate a brewing cycle cold water is admitted to the reservoir for a predetermined time period through an electrically operated fill valve to displace a predetermined volume of heated water from the reservoir. The heated water flows through a beverage filter containing coffee or tea to a serving beaker. A temperature interlock circuit having a temperature sensing element in the reservoir prevents actuation of the fill valve when the reservoir temperature falls below a predetermined minimum level.
