Abstract: A dishwasher includes a washing chamber surrounded by walls. The walls include a water-impermeable inner wall and an insulation layer. At least a first wall of the walls has in a first region on an outside thereof an emission changing device configured to change an emission of thermal radiation. The emission changing device includes a layer having a variable emissivity.

Abstract: The invention relates to a dishwasher comprising a control and display unit having input elements (1, 3, 4, 5, 6, 7, 8) for the selection of a washing program from a plurality of possible programs, at least one display means (2), means for controlling the program parameters, such as the duration and temperature profile of individual program segments, and a turbidity sensor, by means of which a degree of contamination of a rinsing liquor can be detected. According to the invention, the degree of contamination detected by the turbidity sensor is displayed on the display means (2), at least intermittently, thus simplifying operation.

Abstract: A suction nozzle for a vacuum cleaner that can be connected to a suction pipe and/or a suction tube of the vacuum cleaner includes a nozzle part that can be connected to the suction pipe or the suction tube by means of a tubular connection part. A dust sensor is arranged in the flow path of the vacuum cleaner, the signals thereof being evaluated by a battery-operated electronic control device that can be activated by a low-pressure switch. During operation, said control device controls a display device displaying the dust flow. The control device, the low-pressure switch, the display elements displaying the dust flow, and a battery compartment for receiving the batteries are arranged in a housing formed on the upper side of the tubular connection part. The dust sensor is arranged beneath the housing, inside the upper region of the connection part, in the dust air stream.

Abstract: A dishwasher includes a cleaning compartment having a front portion that can be closed by a door. The door is configured to pivot at a bottom section thereof around a horizontally running axis. An illuminating device is configured to illuminate at least one of the cleaning compartment and the front portion of the cleaning compartment. A control device switches the illuminating device on or off based on a opening position of the door. The control device includes a switching element that is actuated by a Bowden cable arranged on the door in order to compensate for the weight of the door.

Abstract: A method for operating a vacuum cleaner having a fan, an electronic control system for the fan and/or another load, and a dust chamber for receiving an air-permeable dust bag, includes providing the dust bag with an identifier, and providing the vacuum cleaner with an identifying device associated with the electronic control system and configured to identify the identifier. When the identifier fails to be identified, at least one of the fan and the other load is controlled using the electronic control system so as to reduce at least one parameter associated with an intake of dust into the dust bag.

Abstract: A dishwasher includes a plurality of spray arms, a recirculation pump driven by an electric motor and a water diverter. The water diverter is disposed on a pressure side of the recirculation pump and is operable to generate flow from an inlet to at least one of a plurality of selectable outlets associated with the spray arms. The water diverter includes at least one blocking element, a drive element driven together with the electric motor of the recirculation pump and configured to move the at least one blocking element, and a transmission disposed between the blocking element and the drive element. The transmission is configured to convert a continuous movement of the drive element into a discontinuous movement of the blocking element.

Abstract: A control system for a dishwasher includes an input device operable to select a wash cycle from a plurality of wash cycles. The input device has a control panel area including a display device, and a plurality of input elements. At least one of the plurality of input elements is operable to select a soil level. A controller is provided, the controller being configured to control cycle parameters and to preselect, based on a selected soil level, a basic wash cycle from a plurality of wash cycles, and to offer different additional cycle options associated with the basic wash cycle based on the selected soil level.

Abstract: A dishwasher includes a washing container, which can be closed by a pivotable door and a control panel. The control panel is disposed on the pivotable door and includes a glazed surface and at least one of a control clement and a display element disposed behind the glazed surface and activatable by touching the glazed surface. The glazed surface is optically switchable so as to change its optical properties between transparent and opaque.

Abstract: The invention relates to a suction nozzle for a vacuum cleaner, that can be connected to a suction pipe and/or a suction tube of the vacuum cleaner. Said suction nozzle (2) comprises a nozzle part that can be connected to the suction pipe or the suction tube of the vacuum cleaner by means of a tubular connection part (2.2). A dust sensor (11) is arranged in the flow path of the vacuum cleaner, the signals thereof being evaluated by a battery-operated electronic control device that can be activated by a low-pressure switch. During operation, said control device controls a display device (9,16) displaying the dust flow. The control device, the low-pressure switch, the display elements (9,16) displaying the dust flow, and a battery compartment (8) for receiving the batteries are arranged in a housing (7) formed on the upper side of the tubular connection part (2.2). The dust sensor is arranged beneath the housing (7), inside the upper region of the connection part (2.2), in the dust air stream.

When the identifier fails to be identified, at least one of the fan and the other load is controlled using the electronic control system so as to reduce at least one parameter associated with an intake of dust into the dust bag.

Abstract: A dishwasher includes a tub, a spraying device and a washing liquid supply device. The spraying device is disposed in the tub and includes a number of spray nozzles. The spraying device is rotatable about a first axis, the first axis being approximately vertical when the dishwasher is in a working position. The washing liquid supply device supplies the spraying device with washing liquid. The spraying device includes a rotatable spray control device that opens and closes a flow path of washing liquid to the spray nozzles so as to provide pulsed spray jets.
