  • Patent number: 11876432
    Abstract: A rotor core includes a hollow shaft and a carrier portion permanently combined with the hollow shaft and configured to carry a ring-shaped permanent magnet coaxially to the hollow shaft. The carrier portion includes a support plate extending in radial direction and at least one axial support region configured to support the ring-shaped permanent magnet in axial direction. The carrier portion further includes at least one support element configured to extend into an interior space surrounded by the ring-shaped permanent magnet. A permanent magnet rotor including the rotor core, an electric motor, an electric pump and a household appliance, are also provided.

  • Publication number: 20230184021
    Abstract: A household dishwasher includes a washing container having a loading opening, a door, an electrical drive device configured to move the door between a closed position, in which the door closes the loading opening, and an open position, in which the washing container is accessible from outside, and a control unit configured to identify a manual movement of the door performed by an operator in a direction of movement by detecting a characteristic variable of the drive device and to move the door further in the direction of movement via the drive device as a result of the manual movement of the door by the operator.

  • Patent number: 11015616
    Abstract: A liquid heating pump includes an impeller chamber having an impeller, which can be rotatably driven, and a diffusor chamber and/or pressure chamber arranged axially downstream in the flow direction and having a stationary diffusor. A heating device is associated with the diffusor and/or pressure chamber. The diffusor has a main body, in particular in the shape of a circular cylinder. The main body has a front wall on which a guide blade portion is arranged which axially protrudes in a direction of the impeller into a liquid ejection region of the impeller arranged around an outer periphery of the impeller and which extends away from the liquid ejection region outwardly toward an axial outer casing of the main body, which axial outer casing is arranged radially further outwardly than the liquid ejection region of the impeller.

  • Patent number: 10716451
    Abstract: A lifting device for a dishwashing machine includes an electrical drive mechanism constructed to move a dishware receptacle of the dishwashing machine between a start position and an end position. A detection unit detects a current draw of the electrical drive mechanism over a travel distance of the dishware receptacle in the dishwashing machine, and an identification unit identifies a status of the lifting device on the basis of the current draw of the electrical drive mechanism detected over the travel distance.

  • Publication number: 20190128284
    Abstract: A liquid heating pump includes an impeller chamber having an impeller, which can be rotatably driven, and a diffuser and/or pressure chamber arranged axially downstream in the flow direction and having a stationary diffuser. A heating device is associated with the diffuser and/or pressure chamber. The diffuser has a main body, in particular in the shape of a circular cylinder, having an axial outer casing, the diameter of which is selected to be at least equal to 80%, in particular between 80% and 90%, preferably approximately equal to 86%, of the external diameter of the diffuser and/or pressure chamber.

  • Patent number: 9997970
    Abstract: A pump has a DC pump drive motor with an electrically driven stator winding and a rotor which is mounted such that it can be driven in rotation in the field of the stator winding. The motor also has a motor shaft, a permanent-magnet ring and a holder which is mounted on the motor shaft and on which the permanent-magnet ring is held. The pump has a rotation-prevention device configured to secure the permanent-magnet ring against rotation about the axis of the rotor on the holder. A domestic appliance, in particular a dishwasher or a washing machine, is provided with a pump of this kind.

  • Publication number: 20170054334
    Abstract: An electric drive motor for a pump includes an electrically actuatable stator winding, and a rotor which is mounted for rotation in a field of the stator winding in the presence of an annular gap. The rotor includes a motor shaft, a magnet carrier disposed on the motor shaft, and at least one permanent magnet arranged on the magnet carrier. The magnet carrier is made from a ferromagnetic chrome steel.
