Abstract

PURPOSE: To automatically conduct the processes from the crushing of coffee beans to extraction, facilitate the cleaning after use, and improve operability by providing guide ribs located near the front face of the discharge port of hot water opened in a hopper and extended to the hopper. CONSTITUTION: A discharge port 33 is opened with one end on the upper side wall of a hopper 13, and hot water is discharged from the opening. Two guide ribs 35 are provided near the front face of the discharge port 33, and they are arranged not to hinder the flow of the discharged hot water. Even when coffee beans approach the vicinity of the discharge port 33, the coffee beans are prevented from entering the discharge port 33 by the guide ribs 35. Since a crushing chamber 10 and a fixed plate 15 are separately formed, the vibration of a motor 19 is hardly conveyed to the crushing chamber 10. The water in a tank 47 is heated by a heating pipe 49, hot water is discharged into the hopper 13 from the discharge port 33 to wash the hopper 13, the hot water is scattered by the rotation of a cutter 23 provided in the crushing chamber 10 to wash the crushing chamber, and it flows into a coffee basket 42 to extract coffee.
