  • the vacuum cleaning device comprising at least one turbine and a filter as suction components.
  • a specific nesting of the suction components within the vacuum cleaner is provided, in which in particular the mentioned suction components are arranged inclined or tilted with respect to a horizontal plane.
  • the invention relates to a vacuum cleaning device which has a proposed arrangement of components in which individual components in the suction head of the vacuum cleaning device form a triangle with one another.
  • vacuum cleaning devices are known, which are used in particular on construction sites in order to suck off dust that occurs in connection with the use of machine tools such as drilling or grinding devices.
  • construction site vacuums usually comprise a suction head in an upper area and a collecting container for the vacuumed up dust in a lower area of the vacuum cleaner.
  • vacuum cleaners are preferably also referred to as industrial vacuum cleaners in the context of the invention.
  • the suction components such as turbine, motor, filter, filter cleaning unit, etc., are arranged essentially vertically and / or horizontally within the vacuum cleaner device.
  • the rigid vertical or horizontal alignment of suction components can lead to individual components having to be cabled to one another in a complex manner if they are not optimally arranged with respect to one another within the suction device. This represents a possibly unnecessary outlay on resources, which makes such a vacuum cleaner device possibly susceptible to errors or leads to increased repair and / or maintenance costs.
  • a rigid vertical or horizontal arrangement of suction components can lead to increased sealing costs. On the one hand, this can manifest itself in the fact that a complex sealing concept must be used. However, it can also manifest itself in an increased cost of materials. Both effects are undesirable in relation to a vacuum cleaner device, since they can lead to increased wear and tear or additional weight and thus to an additional financial burden when operating the vacuum cleaner device. It has also been shown that conventional vacuum cleaning devices, in which the suction components are oriented vertically and / or horizontally with respect to the side walls, lead to increased performance losses.
  • the object of the present invention is to solve the problems described above and to provide a vacuum cleaning device in which the individual suction components are arranged relative to one another in a space-saving manner.
  • the seal should be simple and uncomplicated.
  • a vacuum cleaner that is powerful in relation to the size of the vacuum cleaner device is to be provided, in which, in particular, simple but effective air guidance is possible.

  • the horizontal upper edge of the triangle which is preferably arranged between the turbine and the filter cleaning unit, preferably represents one of the two legs of the essentially right-angled triangle.
  • the second leg of the essentially right-angled triangle is preferably arranged between the filter cleaning unit and the filter, while the Hypotenuse is present between a geometric center of gravity of the filter and a geometric center of gravity of the turbine.
  • the triangle between the suction components is spanned in particular in that the turbine is arranged essentially next to the filter cleaning unit, the filter is arranged essentially below the filter cleaning unit and the turbine is arranged essentially obliquely above the filter.
  • the individual components are tilted to a horizontal and / or vertical axis of the suction head of the vacuum cleaner device.
  • an imaginary first central axis through the filter of the vacuum cleaner with an imaginary horizontal plane forms a first angle between 10 to 20 degrees and an imaginary second central axis through the turbine of the vacuum cleaner with an imaginary horizontal plane forms a second Forms angles between 145 to 155 degrees.

  • This can advantageously be achieved in that a base plate of the suction head forms a central point at which the suction components can be arranged.
  • the inclination of the components in the above-mentioned angular ranges which advantageously leads to the triangular arrangement of the suction components, preferably enables the advantageous, space-saving nesting of the components and the moving of the components together in the suction head.

  • the targeted tilting or inclined arrangement of suction components such as turbines or filters can advantageously increase the available usable container volume so that a larger amount of dust can be picked up and collected with the proposed vacuum cleaner.
  • a particular advantage of the proposed component arrangement for a vacuum cleaning device is that the filter of the vacuum cleaning device can be removed or replaced on the rear of the vacuum cleaning device.

In other words, it is preferred that the second angle is between 148 and 152 degrees and particularly preferably 150 degrees. If the above-described x-axis is extended beyond the y-axis of the coordinate system into the second quadrant and this "negative x-axis" is used as the starting point for determining the size of the second angle of inclination for the turbine, a second angle of inclination results in one Range from 25 to 35 degrees, preferably 28 to 32 degrees and particularly preferably from 30 degrees.
