Patent ID: 7225728

Claim:
A brewing apparatus comprising: a reservoir for storing a heated infusion liquid; a brewing chamber having a drain disposed at a substantially lowermost elevational position; a spray head disposed over the brewing chamber for communicating infusion liquid from the reservoir into the brewing chamber; a flow control valve cooperating with the spray head to regulate flow of infusion liquid into the brewing chamber; a controller communicating with the flow control valve for opening the valve to permit infusion liquid to flow through the flow control valve into the brewing chamber, and for closing the valve to halt infusion liquid from flowing through the flow control valve into the brewing chamber; a memory accessible by the controller and storing a plurality of predetermined intermittent flow profiles each corresponding to a different sequence of opening and closing the flow control valve during a brewing operation, the sequences including (a) a first sequence wherein the valve is open for a selected interval and then the valve is closed for a selected interval, and such pattern repeats for a first period, and where the valve then opens continuously until a predetermined volume of infusion liquid is introduced into the brewing chamber; (b) a second sequence wherein the valve is open for at least one minute during a first period, and where the valve is then intermittently opened for a selected interval and closed for a selected interval during a second period until a predetermined volume of infusion liquid is introduced into the brewing chamber; and (c) a third sequence wherein the valve is adjustably opened and closed by a user created profile; and selectors operably controlled by a user for choosing one of said intermittent flow profiles stored in the memory accessible by the controller.
