Abstract: The invention relates to an air volume flow and pushing force control device for a vacuum cleaner that has at least a motor, a dust receptacle and a suction nozzle, comprising a controller for controlling the motor power, a first sensor for detecting the air volume flow, which in conjunction with the controller forms a first control loop in order to maintain the air volume flow at a prescribed air volume flow value on the basis of the signal of the first sensor. The control device further comprises a second sensor for detecting a pushing force that is required for pushing the suction nozzle, and in conjunction with the controller, forms a second control loop in order to maintain the pushing force below a prescribed value on the basis of the signal of the second sensor, and a control loop selection device that activates one of the two control loops as a function of the signals of the two sensors.

Abstract: An actuating element mounted on an electrical appliance for pivotal movement about a pivoting axis in the switching direction of a switch, in order to switch a function of the electrical appliance by actuating the switch, and comprises a slide with an actuating surface that is guided along a slide path provided on the actuating element to adjust an operating parameter. An operating rocker/slide is provided enabling uniform forces introduced into the operating rocker during displacement of the slide. The actuating element includes the slide path and the pivoting axis extending substantially parallel to each other. The parallel orientation of the pivoting axis and the slide path enables the same length of lever arm to be obtained in relation to the pivoting axis of the actuating element, in each position of the slide, during the introduction of forces into the actuating surface of the slide.

Abstract: A vacuum cleaner comprising a housing containing a housing part for receiving components of electrical appliances, and a dust compartment which can be closed by a dust compartment cover that is mounted in such a way that it can pivot between a position wherein the dust compartment is closed and a position wherein the dust compartment is opened. Said cover is provided with a socket for the electrical supply of additional appliances, said socket being connected to an electrical line leading out of the housing part. The aim of the invention is to ensure the operating safety of the inventive vacuum cleaner over a very long period of time. To this end, the housing is provided with a compartment for automatically inserting a section of the electrical line during the pivoting of the dust compartment cover from the opening position to the closing position.

Abstract: A device for storing a cable, especially an electric cable in a cable drum of a vacuum cleaner. The device including a pendulous body with rollers mounted on an axle and a supply space. The supply space has the rollers arranged on the entry side to guide the cable to the pendulous body. The pendulous body having at least a first and at least a second roller between which the cable can be guided as the pendulous object swings around the axle.

Abstract: A coupling part joins at least one tubular or bar-shaped part to a further part. The coupling part contains at least one sleeve part that accommodates the tubular or bar-shaped part, whereby at least one first detent element is provided on the inside of the sleeve part and interacts with a first counter detent element provided on the tubular or bar-shaped part. The detent connection of the first detent and counter detent element can be disengaged by displacing the sleeve part. A coupling part of the aforementioned type is characterized by its ability to be easily disengaged.

Abstract: A cable reel makes possible a diversion of a braking pulse onto a housing by using elastic elements that mount the cable reel inside the housing, whereby the braking energy is converted into heat. The cable reel is, in particular, also suited for reel bodies that hold long cable lengths. In particular, the cable reel is used in a vacuum cleaner.
