System for dispensing metered volumes of heated water to the brew chamber of a single serve beverage brewer

摘要

A system for dispensing a metered volume of heated water to the brew chamber (16) of a single serve beverage dispenser is disclosed. The system includes a storage tank (10) for containing a supply of water and a dispensing tank (12). A delivery line (14) communicates with the brew chamber and with the dispensing tank at an intermediate level (L) demarcating the interior of dispensing tank into upper and lower compartment (12a, 12b). The volume of the upper compartment (12a) is equal to the metered volume. A vent valve (26) communicates via a vent line (28) with the upper compartment. A supply line (38) connects the storage tank (10) to the lower compartment (12b). An air pump (30) is arranged to deliver pressurized air to the upper compartment. A water pump (36) in the supply line is arranged to deliver water from the storage tank to the lower compartment. A controller (58) controls the components to discharge water from the dispensing tank to the chamber.
