  • Publication number: 20250049255
    Abstract: There is disclosed herein a device (100) compatible with more than one type of portafilter to remove a coffee puck contained within an open compartment of the respective portafilter (180, 182), the coffee puck having an exposed first major face and a second major face in contact with the compartment, the device including: a body (102) providing an interior space (108) and having a rim (118) surrounding an aperture of the space (108), with the rim (118) being configured to engage the respective portafilter such that the first major face of the coffee puck in the open compartment of the respective portafilter (180, 182) communicates with the aperture; a vacuum source (132) to create a pressure differential between the first major face and the second major face of the coffee puck; and a sealing member (158) to sealingly connect the respective portafilter (180, 182) and the rim (118) so that air pressure applied to the first major face is less than air pressure applied to the second major face of the coffee puck

  • Patent number: 12150584
    Abstract: An appliance including: a vessel to receive a liquid, the vessel having a longitudinal axis, a bottom wall, and a side wall at least partly enclosing a chamber within which the liquid is heated, the chamber having an upper region axially spaced from the bottom wall, and a lower region located between the bottom wall and the upper region; a heating element within the chamber; a heater base including at least a portion of an induction coil; connections to deliver an alternating current to the induction coil to deliver a magnetic field to the lower region; the element being movable relative to the coil between an operative position at which the element is located within the lower region to be energised by the magnetic field to cause heating of the element, and an inoperative position at which the element is located in the upper region to not energize the element.

  • Patent number: 12035684
    Abstract: There is disclosed herein a frothing assembly (21) to froth milk in a container (11). The assembly (21) includes: a body (25); a motor (33) fixed to the body and having an output shaft (34) that is rotatably driven about a longitudinal axis (35) of the shaft (34); a frothing device (36) rotatably driven by the shaft (34) and to be submerged in the milk in the container (11); and a perforated member (43) at least partly surrounding the frothing device (36) and spaced from the frothing device (36) by a clearance (44), wherein rotation of the frothing device (36) causes movement of milk in the clearance (44) and movement of milk through the perforated member (43) to be circulated back through the container (11) and the clearance (44) to cause frothing of the milk.

  • Patent number: 11980319
    Abstract: A coffee puck removal device (10) to remove a coffee puck (24) from a portafilter (20) is disclosed herein. The coffee puck removal device (10) has an open compartment (22) containing the coffee puck (24), the coffee puck (24) having an exposed major outer face (26) and a major inner face (28) when the coffee puck (24) is located in the open compartment (22). The device (10) includes: a body (12) having a rim (14) surrounding an aperture (16), with the rim (14) being configured to engage the portafilter (20), with the open compartment (22) facing the body (12) to inhibit air passing between the portafilter (20) and the rim (14); and a vacuum source (30) to remove air from the aperture (16) so that air pressure applied to the major inner face (28) is greater than air pressure applied to the exposed major outer face (26) so that the coffee puck (24) is removed from the portafilter (20).
