Title:
コーヒー飲料準備装置及び方法
Document Type and Number:
Japanese Patent JP6903081
Kind Code:
B2
Abstract:
A coffee brewer contains a brewing unit in which coffee grounds having been poured in are compressed by a plunger driven by an actuator. Heated water flows through the compressed coffee grounds. A control device controls the actuator in accordance with signals of an angle of rotation sensor. The control device first moves the plunger against a stop in an ejection position to calibrate the sensor, then moves the plunger by a predetermined distance in a downwards direction into a pouring-in position. Afterwards the control device moves the plunger by a second distance into the brewing position, a length of the predetermined distance and the second distance corresponds to a number of pulses of the sensor which are stored in the memory. The control device subsequently moves the plunger by a third distance back into the ejection position in which the coffee grounds are removed from the plunger.
