Abstract
A coffee maker with combined milling stage and brewing stage is provided. The coffee maker includes a shaft, a brewing basket, a chopping blade and a locking mechanism. The shaft includes a longitudinal axis and is capable of being rotated about the axis. The brewing basket is adapted to receive coffee beans and hot water. The brewing basket includes a sleeve. A portion of the shaft is movably fitted within the sleeve. The brewing basket is capable of being rotated about the axis. The chopping blade is attached to an end of the shaft and positioned within the brewing basket. The locking mechanism is adapted to lock the brewing basket and unlock the brewing basket. When the brewing basket is locked, rotation of the shaft drives the chopping blade to rotate about the axis to mill the coffee beans to produce milled coffee powder. When the brewing basket is unlocked, rotation of the shaft generates frictional forces on the brewing basket to drive the brewing basket to rotate to generate centrifugal forces, causing the hot water to penetrate the milled coffee powder to produce brewed coffee.
