Coffee maker enabling automated drip brewing

摘要

A coffee maker includes a water storage device having a water tank and a water outlet piping communicating with the water tank; a driving device having a driving motor and a driving shaft; and a swing device having a rotating mechanism mounted on the driving shaft and a shifting mechanism connected to the water outlet piping and moving along with the rotating mechanism when the latter rotates. The water outlet piping is brought by a horizontal rotational movement of the rotating mechanism and a linear movement of the shifting mechanism to swing and shift in a spiral rotational course from a center point to outer and inner areas of a filter in a reciprocating motion while pouring water at controlled volume and stability, enabling ground coffee beans on the filter to be quickly and evenly extracted by water to release aromatic smell and sweet flavor just like drip brewing manually.

主权项

1. A coffee maker, comprising:
a water storage device including a water tank and a water outlet piping communicating with the water tank; a driving device including a driving motor and a driving shaft outwardly extended from the driving motor; and a swing device being mounted between the water outlet piping of the water storage device and the driving shaft of the driving device, the swing device including a rotating mechanism and a shifting mechanism,
the rotating mechanism being mounted on the driving shaft of the driving device, andthe shifting mechanism being connected to the water outlet piping of the water storage device, andthe shifting mechanism being connected to the rotating mechanism to move along with the driving shaft of the driving device, wherein the rotating mechanism brings the whole shifting mechanism to rotate while the shifting mechanism linearly shifts in a horizontal plane, and the water outlet piping is brought by the rotating mechanism and the shifting mechanism, while the coffee maker is in a water discharging state, to rotate and shift in a spiral course.
