Controlled motorized brewing unit

Abstract

A motorized beverage machine () has a brewing unit () that comprises a first assembly () and a second assembly () cooperating together, each assembly () delimiting part of a brewing chamber () for containing an ingredient capsule (). At least one of these assemblies () is: movable away from the cooperating assembly () into an open position within such machine for forming between said assemblies a passage () for inserting into and/or removing from the brewing unit the ingredient capsule (); and movable to the cooperating assembly into a closed position for forming the brewing chamber (). The machine comprises activation means including: a motor for driving the movable assembly between the open and closed positions and transmission means for transmitting the drive action of the motor to the movable assembly; water supply means for supplying heated water to brewing chamber; control means for controlling the drive action of the motor comprising means for measuring at least one electrical parameter representative of the motor power consumption and for comparing the evolution of said measured parameter as a function of time during the transfer of the assembly from the open to the closed position to a set reference and means for providing an input to at least one of the activation means as a result of the compared evolution of the measured parameter to the set reference.
