Abstract: A frothing head for heating and whipping milk is provided. The frothing head has a mixing chamber, a restriction duct extending from the mixing chamber, a frothing chamber arranged at one end of the restriction duct, a distribution duct, an air suction duct leading into the mixing chamber, and a milk suction duct leading into the mixing chamber. The frothing chamber is disc-shaped, and the restriction duct leads tangentially into the frothing chamber. The distribution duct extends axially from a center of a bottom surface of the frothing chamber and has an upper portion and a lower portion having a greater diameter than the upper portion.

Abstract: A device for heating and frothing milk which has a steam generator and a jet pump is provided. The jet pump has a steam inlet through which pressurized steam is injectable into the jet pump, a first suction inlet and a second suction inlet. The first suction inlet is configured to connect to a milk reservoir. An air inlet is connectable or connected to the second suction inlet of the jet pump for drawing air into the jet pump. A bypass valve is connected to the second suction inlet of the jet pump and has a bypass inlet. The bypass valve is switchable between a first position in which the second suction inlet of the jet pump is shut off from the steam generator, and a second position in which the second suction inlet is in fluid communication with the bypass inlet of the bypass valve for suction of steam.

Abstract: A dosing unit (100) for use in an automatic dosing system (20) of a water-bearing household appliance (1), for automatically dosing a dosing amount (122) of a solid detergent, the dosing unit (100) comprising a dosing cartridge (110) for storing a bulk (112) of the solid detergent and a dosing device (120) for separating the dosing amount (122) from the bulk (112) and releasing the separated dosing amount (122) by linearly displacing a sliding element (124) from a separating position to a release position, wherein the dosing device (120) includes a dosing channel (126), wherein, when the sliding element (124) is in the separating position, the dosing channel (126) is configured for receiving at least the dosing amount (122) from the bulk (112) and intermediately storing the dosing amount (122) in a pre-dosing position, and, when the sliding element (124) is in the release position, the dosing device (120) is configured for releasing the dosing amount (122) intermediately stored in the pre-dosing position.
