  • Patent number: 10480112
    Abstract: A method for operating a domestic appliance with a housing, a rotationally movable drum disposed in the housing for receiving laundry, a motor for driving the drum, a control device for controlling the motor, and an evaluation unit. The method, once a program of the domestic appliance has started, includes controlling the motor via the controller such that the drum is driven by the motor and the drum is moved by an angle of less than 90 degrees. Upon attaining the angle the motor is de-energised. The method includes detecting a rotational-speed signal of the drum from when the motor is de-energised over a predetermined first period, and evaluating the detected rotational-speed signals via the evaluation unit by forming a value. The method also includes interrupting the program when the value is greater than a predetermined first threshold value.

  • Patent number: 8904830
    Abstract: A front-loading laundry appliance including a housing with a substantially circular housing opening and a door configured to close the housing opening. A substantially cylindrical container is disposed in the housing and is configured to receive laundry for treatment. The substantially cylindrical container has a substantially circular container opening. The laundry appliance also includes a steam generator with a heating element, an inlet opening and a common outlet opening for water and steam. A pump is configured to deliver water to the inlet opening of the steam generator. A nozzle is disposed in an edge region of the container opening and configured to inject water and steam into the interior of the container.

  • Patent number: 8161662
    Abstract: A method for operating a laundry appliance including a housing having a substantially circular housing opening closable by a door, a substantially cylindrical container disposed within the housing and including a substantially circular container opening and configured to receive laundry for treatment. The laundry appliance also includes a steam generating device including a heating element, an inlet opening and an outlet opening for steam, and a nozzled disposed in a region of the container opening. The method includes activating the heating element until a temperature of the steam generating device reaches a predetermined upper limit. Water is introduced into a tank of the steam generating device at a predetermined flow rate and the temperature of the steam generator device is measured as the water is introduced. The flow rate of water is reduced when the temperature of the steam generator device drops below a lower limit.

  • Patent number: 7823422
    Abstract: A front-loading machine for treating laundry includes a loading opening, a hinged door, a locking mechanism and an operating device. The loading opening is disposed on a front wall of the machine. The hinged door is receivable by a receiving area on the front wall so as to close the loading opening. The locking mechanism is configured to hold the door in a closed position. The operating device is configured to activate and deactivate the locking mechanism. The operating device includes a sensor configured to detect a contact or a contact-free incursion into a detection zone thereof. The sensor is disposed on at least one of the door and the receiving area on the front wall.
