Claims

[Claims for Utility Model Registration] 1. A cylinder with a built-in piston, a filter block combined with the cylinder, and a drive motor for raising and lowering the piston, and the drive motor is operated while coffee powder and hot water raw materials are supplied into the cylinder. In a coffee brewing device that operates the piston downward in a cylinder to extract and filter coffee liquid through a filter, the piston is operated downward intermittently at a predetermined cycle during the pressurizing stroke of the raw material, and the piston is brought to an indestructible point. A coffee brewing device characterized in that it is equipped with drive motor operation control means for temporarily stopping the piston at that position for a predetermined period of time when the piston reaches that position. 2. In the invention extracting device as set forth in claim 1 of the utility model registration claim, the operation control means is a timer that controls the drive motor on and off based on the position detection signal of the material compression start point and bottom dead center of the piston. A coffee brewing device featuring: 3 Utility Model Registration The coffee brewing device according to claim 2, characterized in that the timer is a timer whose intermittent cycle during the downward stroke of the piston and the temporary stop time at the dead point are adjustable. .
