ABSTRACT:
An automatic beverage brewing apparatus including a brew chamber assembly with a throat in a top portion, a drain in a bottom portion, and a filter positioned therebetween. A movable piston controllably opens and closes the throat and drain during brewing and flushing cycles. A discharge line from the brew chamber has a controllable discharge valve to direct flow from the brew chamber through a dispensing line, a waste line, or to prevent flow though either line. Water may be controllably accumulated in the brew chamber by controlling the discharge valve to prevent flow through either line. At the initiation of the brewing cycle the valve is operated to block the dispensing line and the waste line, whereupon a brewing substance and brewing water are introduced into the brew chamber. The brewing substance floats on and steeps in the brewing water which is accumulated in the brew chamber. A pressurized water line dispenses water into the throat to rinses the throat. After the brewing cycle is complete a flushing cycle begins to thoroughly flush the spent brewing substance from the brew chamber. The discharge valve blocks the discharge line to retain water in the brew chamber to float the spent brewing substance off of the filter. Upon floating the brewing substance the drain is opened to remove the float water and substance.
