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.
Claims14
A household dishwasher, comprising:
- 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, the electrical drive device comprising:
- a permanently excited drive motor including a rotor that is mechanically coupled to the door and configured to cause a movement of the rotor in response to a manual movement of the door by an operator, thereby inducing an electrical voltage in the drive motor;
- and
- a control unit configured to identify the manual movement of the door performed by the operator in a direction of movement by detecting a characteristic variable of the electrical 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, the control unit further configured to detect the electrical voltage as the characteristic variable of the electrical drive device and, upon detection of the electrical voltage, to operate the drive motor such that the door is moved further in the direction of movement.
A method for operating a household dishwasher, said method comprising:
- mechanically coupling a rotor of a permanently excited drive motor of an electrical drive device to a door of the household dishwasher;
- enabling movement of the door of the household dishwasher by the electrical drive device between a closed position, in which the door closes a loading opening of a washing container of the household dishwasher, and an open position, in which the washing container is accessible from outside;
- identifying with a control unit a manual movement of the door by an operator in a direction of movement by detecting a characteristic variable of the drive device to cause the door to be moved further in the direction of movement by the drive device;
- and
- moving the door further in the direction of movement when the control unit detects an electrical voltage as the characteristic variable of the drive device, the manual movement of the door inducing the electrical voltage in the drive motor of the drive device by a movement of the rotor of the drive motor.
