ABSTRACT:
Conventional automatic drip coffee makers require about one minute of manual involvement to commence a brewing cycle.
The automatic drip coffee maker herein disclosed makes a full decanter of coffee within 11/2-2 minutes following the one minute manual involvement.
The automatic drip coffee maker of the present invention uses preheated water but only the amount required for a decanter of coffee (1/2 gallon) making it unnecessary to employ a large reservoir. The concept, in a preferred embodiment, is to commence the brewing cycle by an almost instantaneous dump of the preheated water to a transfer tank which, in turn, meters heated water to the grounds at such a rate as to insure almost immediate contact between all the coffee grounds and all the hot water. The dump time for preheated water from the preheated reservoir to the transfer tank is less than the time required to fill a receptacle with cold water. Thus by the time cold water addition may be made to the automatic drip coffee maker, the preheat tank is empty and coffee is in the process of being brewed.
