Abstract:
1. A drip filter coffee maker device, includes: a base; an upright housing that interconnects the base with a head assembly; the head assembly further comprising a removable brew cone; a reservoir comprises a water tank having a level detection sensor; a control module coupled to the level detection sensor for determine the volume of water in the water tank; a burr grinder; the burr grinder adapted to discharge ground coffee into a coffee chute; a coffee chute extending from an exit of the burr grinder to a chute door located about the brew cone for discharging ground coffee into the brew cone; a water outlet located about the brew cone for discharging water into the brew cone; the control module receives data indicative of water volume in the reservoir, and adjust the quantity of coffee beans that are ground and discharged by the burr grinder; and the controller module calculates an “on” time for the burr grinder that is based on the amount of water volume in the reservoir; and the controller module calculates a brew time based on the estimate of ground coffee discharged to the brew cone; and the controller module calculates an effective hot water discharge rate for delivering the water volume in the reservoir over the calculated brew time, wherein the water discharge rate is controlled by on and off cycling of a water boiler.
