  • Patent number: 4969392
    Abstract: A gravity feed coffeemaker includes a water reservoir disposed above a filter basket in which coffee is brewed. The water reservoir has a valve disposed in its bottom, the valve being controlled to open only after the water held in the reservoir has reached a predetermined temperature to provide a substantially even flow of water at a desired temperature across coffee grounds contained in the filter basket. In one embodiment, the valve includes a bladder that is deformable to open the valve. In a second embodiment, a solenoid valve is employed, the solenoid valve having coils wound about a valve body having a centrally located aperture with a plunger disposed therein. The plunger moves in response to an electromagentic field generated when the coils are energized to open the valve.
