A coffee maker comprises a filter basket assembly that enables two coffee dispensing modes. The assembly comprises a filter basket, an actuator that cooperates with a carafe and a motor driven valve. The actuator stops coffee from dispensing when the carafe is removed, but can be defeated by the user to dispense into a cup or mug when the carafe is absent.

1. A filter basket assembly device for a drip filter coffee maker having both a carafe mode and a single serve mode, the device comprising: a filter basket body for holding a coffee filter, the body having a lower surface in which there is a through opening comprising a valve seat;a valve member carried by a valve stem cooperating with the valve seat, the valve member being biased into a normally closed position with respect to the valve seat;an actuator resides below the through opening and is coupled to the valve stem;the actuator is shaped and adapted to cooperate with a carafe, such that when a carafe is presented to the drip filter coffee maker, that carafe impinges on the actuator to thereby lift the valve member for operating in the carafe mode and allowing continuous fluid flow out of the through opening;a lever is hinged with respect to the body, the lever supports the actuator such that hinged movement of the lever with respect to the body causes activation of the actuator to open the valve member with respect to the valve seat; andwherein, in the single serve mode, automatic activation of the actuator is delayed until grounds in the coffee filter have sufficiently brewed in hot water for a predetermined delay; andwherein the actuator can be independently activated by the carafe to enable a the continuous fluid flow out of the through opening to a presented carafe when in carafe mode and the lever to enable an automatic delayed discharged of a single serve of drip filter coffee when in single serve mode. 2. The device of claim 1, wherein: the actuator has one or more coffee discharge openings in it. 3. The device of claim 2, wherein: the actuator has a stem around which are formed the one or more discharge openings for dispensing brewed coffee. 4. The device of claim 1, wherein: an electric motor drives operation of the lever. 5. The device of claim 1, wherein: the valve seat and valve member are conical. 6. The device of claim 1, wherein: the lever is carried by a hinge that is affixed to the basket. 7. The device of claim 1, wherein: the actuator has an inverted dome shape. 8. The device of claim 2, wherein: the actuator has an inverted dome shape. 9. The device of claim 1, further comprising: a carafe adapted to cooperate with the actuator so as to lift the valve member when the carafe impinges on the actuator.
