Title:
BAFFLE OPERATED LIQUID HEATING AND DISPENSING SYSTEM FOR A SINGLE SERVE BEVERAGE BREWER
Document Type and Number:
WIPO Patent Application WO2002080743
Kind Code:
A3
Abstract:
A beverage brewer (10) comprises a storage tank (14) adapted to contain a supply of liquid, and a metering chamber (16) structured and arranged to be filled with a metered amount of liquid received from the storage tank (14) via an inlet in communication therewith. A brewing chamber (44) is structured and arranged to receive a beverage filter cartridge (46) containing a dry beverage medium. A baffle (30) in the storage tank (14) is shiftable from an open position accommodating liquid flow between the storage tank (14) and the metering chamber (16) via its inlet to a closed position preventing such flow and isolating the metering chamber (16) from the storage tank (14). During a brewing cycle, liquid is delivered from the thus isolated metering chamber (16) to the brewing chamber (44) for combination with the beverage medium contained in the filter cartridge (46). At the conclusion of the brewing cycle, the baffle (30) is returned to its open position, thereby allowing the metering chamber (16) to be refilled with liquid received from the storage tank (14) via its inlet.
