发明名称 Dispenser unit for an espresso coffee machine of capsule type, for professional use
摘要 A dispenser unit for an espresso coffee machine of capsule type for professional use, characterised by comprising: - a base (8) connected to the coffee machine and provided with a slidable drawer (10), in which a seat (14) is provided for temporary housing a capsule (12) containing a coffee mixture for preparing a coffee infusion, said drawer (10) being movable between a position outside the base for loading a capsule (12) and a position inside the base for preparing the coffee infusion, said seat (14) being configured such as to ensure that the capsule (12) is maintained therein exclusively by the fact of an outwardly projecting edge (58) thereof resting on the upper edge of said seat (14), - means (16, 18) defining said seat (14) within said drawer (10), which are elastically yieldable to enable a spent capsule (12) to escape from said seat when the drawer is extracted from said base (8), - unidirectional retention means interfering with the upper edge of the capsule (12) housed in said seat (14), such as to yield elastically during insertion of said drawer (10) into the base (8) and to retain the spent capsule during extraction of the drawer from the base, in this manner causing said defining means (16, 18) to yield elastically, with consequent escape of the spent capsule (12) from its seat (14), - members (22) for guiding the sliding movements of said drawer (10) relative to said base (8), - means (28) for supporting a spent capsule (12) caused to escape from said seat (14), and means for its conveying towards a collection container, - a thermal unit (6) with a first piston (48) movable in a controlled manner within a chamber (46) between an inactive position, in which it is raised relative to said capsule (12), and an active position, in which it is made to sealedly adhere to the upper edge (58) of said capsule (12) housed in its seat (14), said first piston (48) being provided longitudinally with a conduit for dispensing pressurized hot water intended to pass through said capsule (12) for preparing the coffee infusion, - a heat exchanger (34) positioned in contact with said thermal unit and provided with a delivery conduit (38) for feeding the pressurized hot water intended for preparing the coffee infusion, - first valve means (40) interposed between said delivery conduit (38) originating from said heat exchanger (34), between a conduit (42) for dispensing the pressurized hot water preparing the coffee infusion, and between a discharge conduit (44) communicating with the outside, said first valve means (40) being controlled to selectively connect said dispensing conduit (42) to said delivery conduit (38) or to said discharge conduit (44), - a control and command unit for the dispenser unit.
