Abstract: A device to grind and tamp including a receptacle for receiving coffee grinds from a grinder that is drivable by a first electric motor, an auger for tamping coffee grinds in the receptacle, and a processor adapted to receive a feedback signal indicating whether the coffee grinds in the receptacle have reached a level threshold value. The auger is drivable by a second electric motor. The processor is further adapted to control the first electric motor and the second electric motor according to a tamp and grind sequence. The tamp and grind sequence includes, for a first time period, operating the first electric motor and the second electric motor and subsequently receiving the level feedback signal.

Abstract: A method of operating a milk frothing device that includes at least one processor operatively associated with one or more actuators. The method is performed by the at least one processor and includes calculating a number of the actuators activated by way of contact with an underside of a vessel, determining a presence or an orientation of the vessel based on the calculated number of the activated actuators, and controlling an operation mode of the milk frothing device based on the determined presence or orientation of the vessel.

Abstract: A steam wand assembly that comprises a steam wand pivotable about a pivot axis and a dampening assembly configured to resist pivotable motion of the steam wand about the pivot axis. The steam wand assembly further includes a bias assembly configured to bias the steam wand in a first direction along the pivot axis such that the dampening assembly is configured to moderate a steam wand velocity in the first direction.

Abstract: A steam wand assembly for an espresso machine has features for preventing overheating of the tip of the steam wand. In a first aspect there is provided a steam wand device comprising a metallic main body tube, a steam hose that passes through the tube, the steam hose also passing through a flexible spacer that is within the tube. In a further aspect there is provided a steam wand device comprising a main body tube having a metallic primary tube and a metallic tip, the primary tube and the tip being attached to one another by a polymeric steam nozzle, the nozzle having a central bore that extends from an inlet adjacent to a lower end of a steam hose to an exit opening.

Abstract: A coffee compacting assembly (22) that receives ground coffee to compact the coffee in a filter cup (25) having a floor (39), the coffee compacting assembly (22) including: an auger (33) having an axis (30) about which the auger (33) is rotated to compact the ground coffee in the filter cup (25), with the auger (33) extending angularly and longitudinally relative to said axis (30); a motor (51) coupled to the auger (33) to rotate the auger (33) about said axis (30); and an auger positioning device (40) engaged with the auger (33) to provide for movement of the auger (33) between a start position and a raised position above the start position, with the start position being predetermined so that the auger (33) is located at a predetermined location within the filter cup (25).

Abstract: There is disclosed herein a coffee machine (10) including: a body (12); a steam wand (14), to froth milk, attached to the body (12); and a cleaning mechanism (20), the cleaning mechanism (20) including: a stem (22) having a first end portion (24) attached to the body (12), and a second end portion (26) extending longitudinally away from the first end portion (24); and a supply of water under pressure to deliver water to the second end portion (26), wherein water under pressure is delivered to the second end portion (26) to produce at least one water jet directed at the steam wand (14).
