Definitions
- the present invention relates to an arrangement of components in a Staubsaugvorrich device, wherein the vacuum cleaner comprises at least one turbine and a filter as Saugerkom components.
- the vacuum cleaner comprises at least one turbine and a filter as Saugerkom components.
- a targeted nesting of the suction components within the vacuum cleaning device is provided, in which in particular the said suction components are arranged at an angle 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 the 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 include 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 vacuum cleaner components such as turbine, motor, filter, filter cleaning unit, etc., are arranged essentially vertically and / or horizontally within the vacuum cleaner device.
- the terms “horizontal” and “vertical” relate in particular to the side walls of the vacuum cleaning device, the terms “vertical arrangement” and “horizontal arrangement” in particular meaning that the suction components are essentially parallel or perpendicular with respect to the side walls of the Vacuum cleaner are arranged.
- the terms “vertical arrangement” and “horizontal arrangement” in particular meaning that the suction components are essentially parallel or perpendicular with respect to the side walls of the Vacuum cleaner are arranged.
- 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 with conventional vacuum cleaning devices, in which the suction components are aligned vertically and / or horizontally with respect to the side walls, increased power losses occur.
- 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 in relation 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. It would also be desirable if the filter or a filter unit of the vacuum cleaner to be provided could be removed from the rear of the vacuum cleaner.
- the object is achieved here by an arrangement of components in a vacuum cleaner device, the vacuum cleaner device comprising at least one turbine, a filter and a filter cleaning unit in a suction head.
- the arrangement is characterized in that the turbine, the filter and the filter cleaning unit in the suction head form a triangle.
- the triangle results in particular in a side view of the suction head of the vacuum cleaning device.
- the three mentioned suction components preferably form the corner points of the triangle.
- the turbine and the filter cleaning unit preferably form an essentially horizontal upper edge of the triangle, the turbine in a front Ren area of the suction head of the vacuum cleaner is arranged and the filter cleaning unit in a rear area.
- the triangle that forms is preferably an essentially right-angled triangle, the right angle of which is in the area of the filter cleaning device.
- 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.
- the aforementioned angular sizes preferably enable the triangular arrangement of the suction components turbine, filter cleaning unit and filter.
- the triangular arrangement of the suction components in the suction head of the vacuum cleaning device preferably enables a compact design for the vacuum cleaning device, in which a number of advantages can be achieved through a targeted nesting of individual suction components.
- the compact arrangement of the suction components, in particular the filter and the turbine the number of parts to be installed in the vacuum cleaning device can be reduced.
- 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 proposed vacuum cleaning device can be designed and manufactured in a simple manner and is advantageously particularly low-maintenance.
- the efficiency of the vacuum cleaner can be increased considerably because the vacuum cleaner can be designed to be particularly compact and space-saving. This also facilitates their handling or use.
- 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. This enables an optimized air flow within the vacuum cleaner. In particular, the volume flow and pressure losses can be significantly reduced due to the improved air routing within the vacuum cleaner.
- the filter and the turbine are arranged tilted with respect to a horizontal plane.
- the mentioned suction components are inclined within the suction head of the vacuum cleaner.
- the inclination of the individual nipple components is defined by an angle of inclination which is formed by an imaginary central axis through the nipple component and an imaginary horizontal plane.
- the imaginary central axis through the filter is referred to in the sense of the invention as the first imaginary central axis of the vacuum cleaner, while the imaginary central axis through the turbine is referred to as the second imaginary central axis of the vacuum cleaner. Accordingly, the angle of inclination of the filter is referred to as the first angle.
- This first angle is preferably in a range between 10 to 20 degrees, in particular inclination angle values between 13 and 17 degrees and particularly preferably of 15 degrees being preferred for the filter. In other words, it is preferred that the first angle is between 13 and 17 degrees and particularly preferably 15 degrees.
- the corresponding first angle is indicated in FIG.
- all values between 10 and 20 degrees can be preferred, in particular the values 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20 and all rational and non-rational intermediate values.
- values between 5 and 25 degrees can also be preferred, in particular 5, 6, 7, 8, 9 or 21, 22, 23, 24, or 25, as well as all rational and non-rational intermediate values.
- the size of the angle of inclination is preferably determined in accordance with the mathematical perspective in that the horizontal plane is viewed as the positive x-axis of a Cartesian coordinate system and the axis through the filter or turbine as a limb or pointer, the included
- the angle between the x-axis and the leg preferably corresponds to the angle of inclination for the respective component.
- the expert recognizes that the first imaginary central axis, which preferably runs centrally through the filter, lies in the first quadrant of such a Cartesian coordinate system, while the second imaginary central axis, which preferably runs centrally through the turbine, lies in the second quadrant of such a system Cartesian coordinate system.
- the angle of inclination of the turbine is referred to as the second angle in the context of the invention. This is preferably in a range between 145 to 155 degrees, with inclination angle values between 148 and 152 degrees and particularly preferably 150 degrees being preferred for the filter. In other words, it is preferred that the second angle is between 148 and 152 degrees and particularly preferably 150 degrees. If the x-axis described above 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 a range from 25 to 35 degrees, preferably 28 to 32 degrees and particularly preferably from 30 degrees.
- all values between 145 and 155 degrees can be preferred, in particular the values 145, 146, 147, 148, 149, 150, 151, 152, 153, 154, 155 and all rational and non-rational intermediate values.
- values between 140 and 160 degrees can also be preferred, in particular 140, 141, 142, 143, 144 or 156, 157, 158, 159 or 160, as well as all rational and non-rational intermediate values.
- This second angle which is determined by the negative x-axis and the central axis through the turbine, is also indicated in FIG.
- the suction components filter and turbine are not aligned horizontally or vertically in relation to the side walls of the suction head of the vacuum cleaning device, but the said suction components assume an inclined position in relation to the outer walls of the vacuum cleaning device by being tilted relative to the imaginary horizontal plane.
- the terms “horizontal” and “vertical” preferably relate to the side walls which are mostly oriented essentially perpendicular to the ground the vacuum cleaner
- the term “horizontal” in the context of the invention preferably means that an object is arranged essentially parallel to the ground or essentially perpendicular to a side wall of the vacuum cleaner
- the term “vertical” preferably means in the context of the invention that an object is arranged essentially perpendicular to the ground or essentially parallel to a side wall of the vacuum cleaner.
- a horizontal plane that can be imagined through the vacuum cleaner is thus an imaginary plane that runs essentially parallel to the earth's surface.
- this preferably means that a straight line which runs in the imaginary horizontal plane forms an angle of approximately 0 degrees with the earth's surface.
- Minimal deviations from the earth's surface in a range of 0 to 5 degrees are preferably covered by the term "horizontal" in the context of the invention, since measurement inaccuracies can occur or because the earth's surface is not always completely flat.
- a tilted or inclined arrangement of a suction component in relation to such a virtual horizontal plane preferably means in the context of the invention that an axis, which preferably runs as an imaginary central axis through the inclined or tilted suction component, encloses an angle with the horizontal plane that is significant is greater than 0.
- This angle is referred to in the context of the invention as the “angle of inclination” of the corresponding suction component.
- the invention is thus characterized by an inclined position of the suction components turbine and filter.

- a negative pressure is generated in the vacuum cleaner device with which the suction flow can be provided for suctioning off the dust.
- the vacuum cleaner device can have further filters or filter elements.
- the tilted filter can also be referred to as a filter cassette or as a main filter in the context of the invention, the filter cassette advantageously now being able to be removed from the proposed vacuum cleaning device from the rear due to the proposed compact design.
- the terms “front” and “rear” or “rear” are not unclear terms for the person skilled in the art in relation to a vacuum cleaner, because the person skilled in the art is familiar with the design and arrangement of the components of the Vacuum cleaner can recognize which is the front and which is the back of the vacuum cleaner.
- a control display with buttons and controls can be provided on the front.
- the proposed vacuum cleaning device can therefore include a filter cleaning unit with which the filter or the filter elements of the vacuum cleaning device can be cleaned manually or automatically.
- the turbine of the proposed vacuum cleaner is arranged next to this filter cleaning unit and that the filter is arranged below this filter cleaning unit. He founders have recognized that this arrangement is particularly advantageous because it enables efficient cleaning of the filter through an optimized alignment of the cleaning unit relative to the filter.
- the filter cleaning unit is located directly above the filter, which in a particularly preferred embodiment of the invention is tilted by 15 degrees with respect to a horizontal plane of the vacuum cleaner device.
- the container volume available for receiving dust is increased considerably, so that advantageously more dust can be collected in the collecting container before it is necessary to empty the collecting container.
- the turbine, the filter and the filter cleaning unit can be particularly compact, i.e. with little free volume between the components, integrated in the proposed vacuum cleaning device who the.
- the air flow i.e.
- the routing of the suction flow inside the vacuum cleaner device can be optimized in the sense that the losses in pressure - for example at the time of filter cleaning - or in volume flow can be reduced considerably.
- the present invention is characterized in a particularly preferred embodiment of the inven tion by a compactness of the component arrangement by a relative arrangement of the components to one another.
- the motor is preferably set up to drive the turbine.
- the vacuum cleaner in this embodiment has a filter cassette inclined by 15 degrees, which can advantageously be removed from the clean room side of the vacuum cleaner, although the filter cassette is arranged below the motor or turbine of the vacuum cleaner.
- the arrangement of an object below another object can mean in the context of the invention that the first object is arranged directly below the second object. In the context of the invention, however, it can also be preferred that the first object is arranged laterally offset from the second object, ie it is present at an angle below the second object.
- the invention enables a simplified air flow through the preferred inclined motor position.
- a connection of the process air corridors can thus be achieved, which preferably relates to the filtration area, the negative pressure area, the guide area and / or the overpressure area of the vacuum cleaner.
- the invention relates to a vacuum cleaner device, the vacuum cleaner device having an arrangement of components according to one or more of the preceding claims.
