Definitions
- the invention relates to a dust bag for a vacuum cleaner with a holding device for fastening in a dust chamber of the vacuum cleaner, with an inlet opening for receiving a dust-laden air flow of the vacuum cleaner being embedded in the holding device, with a filter bag made of an air-permeable material open to the inlet opening on the holding device is arranged, wherein the material of the filter bag is designed to filter the dust from the air flow when the air flow passes through.
- Vacuum cleaners with dust bags are used in private households and in industry to clean surfaces such as textile floor coverings and smooth floors.
- the floor surface can be covered by a textile floor covering such as a rug or carpeting or by a hard floor such as e.g. B. a wooden parquet, laminate or PVC flooring can be formed.
- a vacuum cleaner has a fan for generating a negative pressure, through which a floor nozzle guided over a floor surface to be cleaned picks up dust and dirt from the floor surface.
- the user moves the floor nozzle back and forth in the working direction by means of pushing and pulling movements. As a result, the floor nozzle slides over the floor surface to be cleaned.
- the underside of the floor nozzle slides over the carpet, while in the case of smooth floors the underside floats over these floor surfaces at a distance, possibly using spacer bristles.
- the user can, for example, manipulate a vacuum cleaner handle connected to the suction tube.
- the vacuum cleaner can also be designed as an independently moving vacuum cleaner, in particular a vacuum robot, so that the working direction of the floor nozzle corresponds to the direction of travel of the independently moving vacuum cleaner.
- a dust bag for a vacuum cleaner usually includes a holding plate for fastening in a dust chamber of the vacuum cleaner, with an inlet opening for receiving a dust-laden air flow of the vacuum cleaner being let into the holding plate, with a filter bag made of an air-permeable material, which is open to the inlet opening, being arranged on the holding plate is, the material of the filter bag being designed to filter the dust out of the air flow when the air flow passes through.
- the inlet opening embedded in the holding plate is provided with a flap, which closes the dust bag when it is removed from the dust compartment, so that dust collected in the filter bag cannot escape through the inlet opening.
- the inlet opening is regularly provided with a seal, which pushes the dust bag toward an inlet connector of the inlet opening that dips into the inlet opening vacuum cleaner seals.
- the holding plate regularly offers a handle with which the dust bag can be handled by the user when changing the bag.
- the invention therefore faces the problem of specifying an improved dust bag.
- the amount of waste should be reduced by changing the dust bag and handling when changing the dust bag should be simplified.
- a dust bag having the features of patent claim 1 . Due to the fact that the holding device is designed as a docking element surrounding the inlet opening, with the docking element forming an undercut for fastening the dust bag in a vacuum cleaner, a particularly simply constructed dust bag can be created which offers a simple and secure fastening option in the dust chamber of a vacuum cleaner.
- the dust bag can be fastened firmly and tightly to an inlet connector of the vacuum cleaner that dips into the inlet opening via the peripheral docking element. For this purpose, fastening elements of the vacuum cleaner can simply engage in the undercut on the peripheral docking element.
- the simply constructed docking element which surrounds the inlet opening of the filter bag, can be securely positioned in the dust chamber.
- the simple design of the holding device reduces the waste generated by the dust bag when changing the dust bag considerably.
- the docking element preferably completely surrounds the inlet opening of the dust bag. In an alternative embodiment, however, it is also conceivable that the docking element only partially surrounds the inlet opening of the dust bag.
- the holding device is preferably simply welded to the material of the filter bag.
- the described holding device makes it possible to produce the entire dust bag, including the simple holding device, from a single type of material. For example, a polypropylene-based nonwoven fabric for the filter bag with a simple holding device, also made of polypropylene, is conceivable.
- the dust bag and the holding device from a material based on natural fibers, such as paper or cardboard.
- the filter bag is made of paper and the holding device is made of cardboard.
- the docking element is designed as a docking ring or as a docking ring segment. In the embodiment as a docking ring, this completely surrounds the inlet opening of the dust bag. In the embodiment as a docking ring segment, the inlet opening of the dust bag can also be only partially surrounded by the docking ring segment.
- the undercut makes it possible to fix the holding device axially in the flow direction of the air flow through the inlet opening.
- the holding device can be easily fixed axially in both directions of the air flow in the dust chamber of the vacuum cleaner.
- particularly simply designed fastening elements of the vacuum cleaner can hold the holding device of the dust bag on the docking element in the dust chamber. This effectively prevents the simply constructed holding device from slipping in the dust compartment.
- An embodiment is particularly preferred which provides that the undercut is formed on a socket formed by the docking element on the inlet opening so that it is accessible from the outside.
- Fastening elements of the vacuum cleaner can very easily engage from the outside in the undercut on the connection piece of the docking element via the undercut accessible from the outside and securely position the connection piece with the inlet opening of the filter bag.
- the dust bag is securely fixed in the dust chamber simply by fastening elements of the vacuum cleaner engaging the docking element from the outside and engaging in the undercut.
- a particularly advantageous embodiment of the invention relates to the fact that the undercut is formed in a socket formed by the docking element at the inlet opening so that it is accessible from the inside.
- fastening elements of the vacuum cleaner can engage from the inside in the undercut on the connection piece of the docking element in a very space-saving manner and securely position the connection piece with the inlet opening of the filter bag.
- the dust bag is securely fixed in the dust chamber simply by means of fastening elements of the vacuum cleaner which act on the docking element from the inside and engage in the undercut.
- a particularly advantageous embodiment of the invention therefore provides that the docking element has anti-twist protection.
- the twist protection can be used to ensure that the preferably rotationally symmetrical docking element does not twist in the fastening elements of the vacuum cleaner.
- an advantageous embodiment of the invention provides that the anti-twist protection is formed by a semicircular indentation.
- the semicircular indentation provides particularly simple anti-twist protection for the docking element.
- the fastening elements of the vacuum cleaner advantageously have a projection which engages in the semicircular indentation. The docking element can thus be effectively secured against twisting when it is received in the fastening elements of the vacuum cleaner, so that the dust bag remains optimally positioned in the dust compartment of the vacuum cleaner.
- An embodiment which provides that the docking ring is composed of two partial rings forming the undercut is particularly advantageous.
- a particularly simple production of the undercut, in particular by injection molding, preferably from plastic, is possible via the two partial rings forming the undercut.
- the two partial rings can be demolded particularly easily from a very simply constructed injection mold.
- An advantageous embodiment of the invention provides that the ring parts are connected via a film hinge, with the film hinge positioning the ring parts appropriately for folding the docking ring together.
- the two partial rings of the docking ring, connected via the film hinge can be produced via the film hinge in an injection molding process in an injection mold using the injection molding process, preferably from plastic.
- the partial rings then simply have to be folded together and pushed together in just one assembly step on the film hinge to form the undercut in the docking ring. Since the partial rings are already positioned to match one another via the film hinge, the assembly step can also be taken over by a simple machine, so that a high degree of automation is achieved in the production of the dust bag.
- the inlet opening is formed by at least one slit-shaped incision in the material of the filter bag.
- the slit-shaped incision in the material of the filter bag replaces the flat punching out of the filter bag material to create the inlet opening.
- a flat inlet opening in filter bags is nowadays usually closed by a flap on the holding device surrounding the inlet opening, such a flap can be dispensed with in the dust bag according to the invention.
- the slot-shaped incision can be made through the docking ring of the holding device Push the vacuum cleaner inlet nozzle into the filter bag so that the dust-laden air flow from the vacuum cleaner can be directed into the dust bag.
- the inlet nozzle of the vacuum cleaner When changing a full dust bag, the inlet nozzle of the vacuum cleaner is removed from the dust bag. A flap then usually closes the flat inlet opening so that no dust can escape when handling the full dust bag.
- This type of complicated hygienic closure can be dispensed with with the slit-shaped incision in the material of the dust bag.
- the material of the filter bag surrounding the slit of the inlet opening slides back when it leaves the inlet connection and again closes the slit of the inlet opening to such an extent that dust can be effectively prevented from escaping with these simple means.
- the incision in the material of the filter bag for the inlet opening is U-shaped, cross-shaped, star-shaped, straight or circular.
- the inlet opening should therefore not be completely punched out in a circle, as is usual with today's dust bags, but should preferably be cut as a U-shaped slit in the material of the filter bag.
- other shapes are also possible, which can effectively prevent the escape of dust from the inlet opening and still allow the inlet connection piece of the vacuum cleaner to be easily immersed.
- FIG. 1 a dust bag is shown purely schematically.
- the representation according to figure 1 shows a dust bag 1 according to the invention for a vacuum cleaner with a holding device 2 for attachment in a dust compartment of the vacuum cleaner.
- the holding device 2 surrounds an inlet opening 3 for receiving an air flow 4 laden with dust from the vacuum cleaner. This means that the inlet opening 3 is let into the holding device 2 .
- a filter bag 5 open to the inlet opening 3 connects to the holding device 2 .
- This filter bag 5 is made of an air-permeable.
- the filter bag 5 is preferably welded to the holding device 2 around the inlet opening 3 .
- the material of the filter bag 5 is designed to filter the dust out of the air flow 4 when the air flow 4 is allowed to pass through.
- the holding device 2 is designed as a docking ring 6 surrounding the inlet opening 3 .
- This docking ring 6 forms an undercut 7, which is used to attach the dust bag 1 in a vacuum cleaner.
- a dust bag 1 of particularly simple construction can be created which offers a simple and secure fastening option in the dust compartment of a vacuum cleaner.
- the peripheral docking ring 6 enables the dust bag 1 to be fastened firmly and tightly to an inlet connection piece of the vacuum cleaner which dips into the inlet opening 3 .
- the inlet opening 3 is also formed by a slit-shaped incision 13 in the material of the filter bag 5 .
- This slit-shaped incision 13 in the material of the filter bag 5 replaces a conventional two-dimensional punching out of the filter bag material to produce the inlet opening 3.
- the inlet connector of the vacuum cleaner which is guided through the docking ring 6 of the holding device 2, can penetrate through the slit-shaped incision 13 into the filter bag 5, so that the dust-laden air flow 4 of the vacuum cleaner can be directed into the dust bag 1. If the full dust bag 1 is changed, the vacuum cleaner's inlet socket is removed from the dust bag 1, and the material of the filter bag 5 surrounding the slot 13 of the inlet opening 3 slips back when it leaves the inlet socket and largely closes the slot 13 of the inlet opening 3 again, so that dust escape can be effectively prevented with these simple means.
- the incision 13 in the material of the filter bag 5 is straight.
- the incision 13 can also be U-shaped, cross-shaped, star-shaped or circular.
- the inlet opening 3 is not flat, but cut into the material of the filter bag 5 like a slit.
- the figure 2 shows a detailed view of the holding device according to FIG figure 1 .
- the undercut 7, which makes the holding device 2 fixable axially in the flow direction of the air flow 4 through the inlet opening 3, can be seen better.
- the undercut 7 is formed on the inlet opening 3 so that it is accessible from the inside in a socket 8 formed by the docking ring 6 .
- the undercut 7, which is accessible from the inside, allows fastening elements of the vacuum cleaner to engage from the inside in the undercut 7 on the socket 8 of the docking ring 6 in a very space-saving manner.
- the docking ring 6 of the holding device 2 can be effectively secured against twisting when it is received in the fastening elements of the vacuum cleaner. So the dust bag 1 ( 1 ) remain optimally positioned in the dust compartment of the vacuum cleaner via the fastening elements of the vacuum cleaner.
- FIG 3 is the holding device 2 according to figure 2 shown in the unfolded state.
- the docking ring 6 ( 2 ) from two the undercut 7 ( 2 ) forming partial rings 10, 11 is composed.
- the two partial rings 10, 11 are connected to one another via a film hinge 12.
- the partial rings 10, 11 for folding the docking ring 6 ( 2 ) appropriately positioned.
- the partial rings 10, 11 can be produced by injection molding, preferably from plastic.
- the formation of the undercut 7 from the two partial rings 10, 11 enables an injection mold of particularly simple design, from which the partial rings 10, 11 can be demolded particularly easily.
- the two partial rings 10, 11 can then be easily attached to the film hinge 12 in one assembly step to form the undercut 7 ( 2 ) in docking ring 6 ( 2 ) fold and squeeze.
- the connection between the partial rings 10, 11 can be done by gluing, screwing, hot caulking, riveting, latching or preferably welding, so that a form-fitting retaining plate assembly is formed. Due to the fact that the partial rings 10, 11 are already positioned to match one another via the film hinge 12, the assembly step can also be automated by a machine.
- FIG 4 a further embodiment of a dust bag 1 according to the invention is shown.
- the execution according to figure 4 differs from the execution according to figure 1 in that the undercut 7 is formed here on the inlet opening 3 on the connecting piece 8 formed by the docking ring 6 so that it is accessible from the outside.
- This dust bag 1 also has a holding device 2 for attachment in a dust compartment of the vacuum cleaner.
- this holding device 2 surrounds the inlet opening 3 for receiving a dust-laden air flow 4 of the vacuum cleaner. This means that the inlet opening 3 is also let into the holding device 2 .
- the holding device 2 is adjoined by a filter bag 5 which is open towards the inlet opening 3 .
- This filter bag 5 is also made of an air-permeable material.
- the filter bag 5 is welded to the holding device 2, preferably around the inlet opening 3.
- the filter bag 5 is welded together from a material that filters the dust out of the air flow 4 when the air flow 4 passes through.
- the filter bag 5 is designed as a gusseted bag.
- the holding device 2 is also designed according to the invention as a docking ring 6 running around the inlet opening 3 .
- the docking ring 6 forms an undercut 7, which is used to attach the dust bag 1 in a vacuum cleaner. This results in a dust bag 1 of particularly simple construction, which enables a simple and secure fastening option in the dust compartment of a vacuum cleaner.
- the dust bag 1 can be fastened firmly and tightly very easily to an inlet connection piece of the vacuum cleaner that dips into the inlet opening 3 via the peripheral docking ring 6 .
- the inlet port 3 is in figure 4 also formed by a cross-slit-shaped incision 13 in the material of the filter bag 5.
- This cross-slot-shaped incision 13 in the material of the filter bag 5 replaces the usual two-dimensional punching out of the filter bag material to produce the inlet opening 3.
- the cross-slit-shaped incision 13 can be used to easily insert the inlet connection of the vacuum cleaner, which is guided through the docking ring 6 of the holding device 2, into the filter bag 5 of the Anther 1 advance. This allows the dust-laden air flow of the vacuum cleaner to be directed into the dust bag 1.
- the full dust bag 1 can be changed when the vacuum cleaner's inlet socket is removed from the dust bag 1.
- the material of the filter bag 5 forming the cross slot 13 of the inlet opening 3 folds back when it leaves the inlet socket and largely closes the cross slot 13 of the inlet opening 3, so that dust can be effectively prevented from escaping with very simple means.
- the figure 5 shows a detailed view of the holding device 2 according to FIG figure 4 .
- This view shows the undercut 7 in the docking ring 6 more clearly.
- the holding device 2 can be fixed axially in the flow direction of the air flow 4 through the inlet opening 3 via this undercut 7 .
- the undercut 7 is formed on the inlet opening 3 and is accessible from the outside on a connecting piece 8 formed by the docking ring 6 .
- This undercut 7, which is accessible from the outside, makes it possible for the fastening elements of the vacuum cleaner to easily engage in the undercut 7 on the connecting piece 8 of the docking ring 6 from the outside.
- the socket 8 can be connected to the inlet opening 3 of the filter bag 5 ( 4 ) easily and safely in the dust compartment of the dust bag 1 ( 4 ) equipped vacuum cleaner can be positioned.
- the representation in figure 5 shows that the anti-rotation device 9 on the docking ring 6, which as a semi-circular Indentation is formed, is accessible from the outside.
- the fastening elements of the vacuum cleaner can thus engage in the semicircular indentation 9 with a projection from the outside.
- the docking ring 6 of the holding device 2 can be securely secured against twisting when it is received in the fastening elements of the vacuum cleaner. This allows the dust bag 1 ( 4 ) remain optimally positioned in the dust chamber of the vacuum cleaner via the fastening elements.
- FIG 6 is the holding device according to figure 5 shown in the unfolded state. It can be seen here that the docking ring 6 ( figure 5 ) also from two the undercut 7 ( figure 5 ) forming partial rings 10, 11 is composed. These two partial rings 10, 11 can be folded together via a film hinge 12. The film hinge 12 positions the partial rings 10, 11 for folding the docking ring 6 ( figure 5 ) already suitable. This allows the partial rings 10, 11 to be particularly easy to form the undercut 7 ( figure 5 ) forming docking ring 6 ( figure 5 ) connect to each other. The production of the undercut 7 ( figure 5 ) is so through the two the undercut 7 ( figure 5 ) forming partial rings 10, 11 particularly easy. These partial rings 10, 11 can easily be produced by injection molding, preferably from plastic.
- the two partial rings 10, 11 enable an injection mold of particularly simple construction.
- the partial rings 10, 11 can be removed from the mold particularly easily from this mold. Thanks to the film hinge 12, the two partial rings 10, 11 of the docking ring 6 ( figure 5 ) as a component in an injection process in an injection mold using the injection molding process, preferably made of plastic.
- the two partial rings 10, 11 connected via the film hinge 12 can then be easily assembled in one assembly step to form the undercut 7 ( figure 5 ) in docking ring 6 ( figure 5 ) on the film hinge 12 are folded and compressed. Due to the fact that the partial rings 10, 11 are already positioned to match one another via the film hinge 12, the assembly step can also be carried out automatically by a simple robot.

Description
Die Erfindung betrifft einen Staubbeutel für einen Staubsauger mit einer Haltevorrichtung zur Befestigung in einem Staubraum des Staubsaugers, wobei in die Haltevorrichtung eine Einlassöffnung zur Aufnahme eines mit Staub beladenen Luftstromes des Staubsaugers eingelassen ist, wobei an der Haltevorrichtung ein zur Einlassöffnung offener Filterbeutel aus einem luftdurchlässigen Material angeordnet ist, wobei das Material des Filterbeutels dazu ausgebildet ist bei Durchlass des Luftstromes den Staub aus dem Luftstrom zu filtern.The invention relates to a dust bag for a vacuum cleaner with a holding device for fastening in a dust chamber of the vacuum cleaner, with an inlet opening for receiving a dust-laden air flow of the vacuum cleaner being embedded in the holding device, with a filter bag made of an air-permeable material open to the inlet opening on the holding device is arranged, wherein the material of the filter bag is designed to filter the dust from the air flow when the air flow passes through.
Im privaten Haushalt sowie im Gewerbe kommen Staubsauger mit Staubbeuteln zur Reinigung von Flächen wie textilen Bodenbelägen und glatten Böden zum Einsatz. Die Bodenfläche kann durch einen textilen Bodenbelag wie einen Teppich oder Teppichboden oder durch einen Hartboden wie z. B. ein Holzparkett, Laminat oder einen PVC-Bodenbelag gebildet werden. Ein solcher Staubsauger weist ein Gebläse zur Erzeugung eines Unterdruckes auf, durch den eine über eine zu reinigende Bodenfläche geführte Bodendüse Staub und Schmutz von der Bodenfläche aufnimmt. Hierzu wird die Bodendüse durch den Benutzer oder die Benutzerin mittels Schub- und Zugbewegungen in Bearbeitungsrichtung vor und zurückbewegt. Hierdurch gleitet die Bodendüse über die zu reinigende Bodenfläche. Insbesondere bei langflorigen Teppichen gleitet die Unterseite der Bodendüse über den Teppich, während die Unterseite bei Glattböden beabstandet, gegebenenfalls durch Abstandsborsten, über diese Bodenflächen hinweg schwebt. Der Benutzer oder die Benutzerin kann dazu beispielsweise einen mit dem Saugrohr verbundenen Griff des Staubsaugers handhaben. Der Staubsauger kann auch als selbstständig fahrender Staubsauger, insbesondere Saugroboter, ausgebildet sein, sodass die Bearbeitungsrichtung der Bodendüse der Fahrtrichtung des selbstständig fahrenden Staubsaugers entspricht.Vacuum cleaners with dust bags are used in private households and in industry to clean surfaces such as textile floor coverings and smooth floors. The floor surface can be covered by a textile floor covering such as a rug or carpeting or by a hard floor such as e.g. B. a wooden parquet, laminate or PVC flooring can be formed. Such a vacuum cleaner has a fan for generating a negative pressure, through which a floor nozzle guided over a floor surface to be cleaned picks up dust and dirt from the floor surface. For this purpose, the user moves the floor nozzle back and forth in the working direction by means of pushing and pulling movements. As a result, the floor nozzle slides over the floor surface to be cleaned. In the case of long-pile carpets in particular, the underside of the floor nozzle slides over the carpet, while in the case of smooth floors the underside floats over these floor surfaces at a distance, possibly using spacer bristles. For this purpose, the user can, for example, manipulate a vacuum cleaner handle connected to the suction tube. The vacuum cleaner can also be designed as an independently moving vacuum cleaner, in particular a vacuum robot, so that the working direction of the floor nozzle corresponds to the direction of travel of the independently moving vacuum cleaner.
Ein Staubbeutel für einen Staubsauger umfasst heute üblicherweise eine Halteplatte zur Befestigung in einem Staubraum des Staubsaugers, wobei in die Halteplatte eine Einlassöffnung zur Aufnahme eines mit Staub beladenen Luftstromes des Staubsaugers eingelassen ist, wobei an der Halteplatte ein zur Einlassöffnung offener Filterbeutel aus einem luftdurchlässigen Material angeordnet ist, wobei das Material des Filterbeutels dazu ausgebildet ist bei Durchlass des Luftstromes den Staub aus dem Luftstrom zu filtern. Bei vielen Staubbeuteln ist die in die Halteplatte eingelassene Einlassöffnung mit einer Klappe versehen, welche den Staubbeutel bei der Entnahme aus dem Staubraum verschließt, damit im Filterbeutel gesammelter Staub nicht über die Einlassöffnung wieder austreten kann. Außerdem ist die Einlassöffnung regelmäßig mit einer Dichtung versehen, welche den Staubbeutel hin zu einem in die Einlassöffnung eintauchenden Einlassstutzen des Staubsaugers abdichtet. Außerdem bietet die Halteplatte regelmäßig einen Griff über welchen der Staubbeutel von dem Benutzer beim Wechsel des Beutels gehandhabt werden kann. Diese zahlreichen Komponenten der Staubbeutel bestehen oft aus unterschiedlichsten Materialien und werden mit dem Wechsel des Staubbeutels mit ausgetauscht. Dies ist nicht sonderlich nachhaltig oder Ressourcen schonend, da die miteinander verbundenen Materialen der mit ausgetauschten Komponenten nur sehr aufwendig recyclebar sind. Auch alleine die Masse, der mit dem Filterbeutel zusammen entsorgten Komponenten erzeugt eine erhebliche und unnötige Müllmenge.Today, a dust bag for a vacuum cleaner usually includes a holding plate for fastening in a dust chamber of the vacuum cleaner, with an inlet opening for receiving a dust-laden air flow of the vacuum cleaner being let into the holding plate, with a filter bag made of an air-permeable material, which is open to the inlet opening, being arranged on the holding plate is, the material of the filter bag being designed to filter the dust out of the air flow when the air flow passes through. In many dust bags, the inlet opening embedded in the holding plate is provided with a flap, which closes the dust bag when it is removed from the dust compartment, so that dust collected in the filter bag cannot escape through the inlet opening. In addition, the inlet opening is regularly provided with a seal, which pushes the dust bag toward an inlet connector of the inlet opening that dips into the inlet opening vacuum cleaner seals. In addition, the holding plate regularly offers a handle with which the dust bag can be handled by the user when changing the bag. These numerous components of the dust bag are often made of a wide variety of materials and are replaced when the dust bag is changed. This is not particularly sustainable or does not conserve resources, since the materials connected to the replaced components can only be recycled with great effort. The mass alone of the components disposed of together with the filter bag generates a significant and unnecessary amount of waste.
Der Erfindung stellt sich somit das Problem, einen verbesserten Staubbeutel anzugeben. Insbesondere soll die Müllmenge durch den Staubbeutelwechsel reduziert und die Handhabung beim Staubbeutelwechsel vereinfacht werden.The invention therefore faces the problem of specifying an improved dust bag. In particular, the amount of waste should be reduced by changing the dust bag and handling when changing the dust bag should be simplified.
Erfindungsgemäß wird dieses Problem durch einen Staubbeutel mit den Merkmalen des Patentanspruchs 1 gelöst. Dadurch, dass die Haltevorrichtung als ein die Einlassöffnung umlaufendes Andockelement ausgebildet ist, wobei das Andockelement einen Hinterschnitt zur Befestigung des Staubbeutels in einem Staubsauger bildet, kann ein besonders einfach aufgebauter Staubbeutel geschaffen werden, der eine einfache und sichere Befestigungsmöglichkeit im Staubraum eines Staubsaugers bietet. Über das umlaufende Andockelement kann der Staubbeutel fest und dicht an einem in die Einlassöffnung eintauchenden Einlassstutzen des Staubsaugers befestigt werden. Hierzu können Befestigungselemente des Staubsaugers einfach in den Hinterschnitt am umlaufenden Andockelement eingreifen. Dadurch kann das einfach aufgebaute Andockelement, welcher die Einlassöffnung des Filterbeutels umgibt, sicher in dem Staubraum positioniert werden. Der einfache Aufbau der Haltevorrichtung reduziert den beim Staubbeutelwechsel durch den Staubbeutel anfallenden Müll erheblich. Bevorzugt umgibt das Andockelement die Einlassöffnung des Staubbeutels vollständig. In einer alternativen Ausführungsform ist es aber auch denkbar, dass das Andockelement die Einlassöffnung des Staubbeutels nur teilweise umgibt. Die Haltevorrichtung ist bevorzugt einfach mit dem Material des Filterbeutels verschweißt. Darüber hinaus ist es durch die beschriebene Haltevorrichtung möglich den gesamten Staubbeutel inklusive der einfachen Haltevorrichtung sortenrein aus einem einzigen Material herzustellen. So ist beispielsweise ein Polypropylen-basierter Vliesstoff für den Filterbeutel mit einfacher Haltevorrichtung ebenfalls aus Polypropylen denkbar. Dies vereinfacht auch das Recycling des Staubbeutels erheblich. In einer weiteren Ausführungsform ist es denkbar, den Staubbeutel und die Haltevorrichtung aus einem naturfaserbasierten Material, wie Papier oder Pappe auszuführen. Hierbei ist der Filterbeutel aus Papier und die Haltevorrichtung aus Pappe ausgeführt.According to the invention, this problem is solved by a dust bag having the features of patent claim 1 . Due to the fact that the holding device is designed as a docking element surrounding the inlet opening, with the docking element forming an undercut for fastening the dust bag in a vacuum cleaner, a particularly simply constructed dust bag can be created which offers a simple and secure fastening option in the dust chamber of a vacuum cleaner. The dust bag can be fastened firmly and tightly to an inlet connector of the vacuum cleaner that dips into the inlet opening via the peripheral docking element. For this purpose, fastening elements of the vacuum cleaner can simply engage in the undercut on the peripheral docking element. As a result, the simply constructed docking element, which surrounds the inlet opening of the filter bag, can be securely positioned in the dust chamber. The simple design of the holding device reduces the waste generated by the dust bag when changing the dust bag considerably. The docking element preferably completely surrounds the inlet opening of the dust bag. In an alternative embodiment, however, it is also conceivable that the docking element only partially surrounds the inlet opening of the dust bag. The holding device is preferably simply welded to the material of the filter bag. In addition, the described holding device makes it possible to produce the entire dust bag, including the simple holding device, from a single type of material. For example, a polypropylene-based nonwoven fabric for the filter bag with a simple holding device, also made of polypropylene, is conceivable. This also greatly simplifies the recycling of the dust bag. In a further embodiment, it is conceivable to design the dust bag and the holding device from a material based on natural fibers, such as paper or cardboard. The filter bag is made of paper and the holding device is made of cardboard.
Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den nachfolgenden abhängigen Ansprüchen. Es ist darauf hinzuweisen, dass die in den Ansprüchen einzeln aufgeführten Merkmale auch in beliebiger und technologisch sinnvoller Weise miteinander kombiniert werden können und somit weitere Ausgestaltungen der Erfindung aufzeigen.Advantageous configurations and developments of the invention result from the following dependent claims. It should be pointed out that the features listed individually in the claims can also be combined with one another in any technologically meaningful manner and thus show further refinements of the invention.
In einer bevorzugten Ausführungsform ist das Andockelement als Andockring oder als Andockringsegment ausgebildet. In der Ausführungsform als Andockring umgibt dieser die Einlassöffnung des Staubbeutels vollständig. In der Ausführungsform als Andockringsegment kann die Einlassöffnung des Staubbeutels auch nur teilweise vom Andockringsegment umgeben werden.In a preferred embodiment, the docking element is designed as a docking ring or as a docking ring segment. In the embodiment as a docking ring, this completely surrounds the inlet opening of the dust bag. In the embodiment as a docking ring segment, the inlet opening of the dust bag can also be only partially surrounded by the docking ring segment.
Gemäß einer vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass der Hinterschnitt die Haltevorrichtung axial in Strömungsrichtung des Luftstromes durch die Einlassöffnung festlegbar macht. Mit dem Hinterschnitt kann die Haltevorrichtung einfach axial in beiden Richtungen des Luftstromes im Staubraum des Staubsaugers festgelegt werden. Mit der beidseitigen Begrenzung durch den Hinterschnitt, können besonders einfach ausgestaltete Befestigungselemente des Staubsaugers die Haltevorrichtung des Staubbeutels an dem Andockelement im Staubraum festhalten. Damit kann ein Verrutschen der einfach aufgebauten Haltevorrichtung im Staubraum wirksam verhindert werden.According to an advantageous embodiment of the invention, it is provided that the undercut makes it possible to fix the holding device axially in the flow direction of the air flow through the inlet opening. With the undercut, the holding device can be easily fixed axially in both directions of the air flow in the dust chamber of the vacuum cleaner. With the delimitation on both sides by the undercut, particularly simply designed fastening elements of the vacuum cleaner can hold the holding device of the dust bag on the docking element in the dust chamber. This effectively prevents the simply constructed holding device from slipping in the dust compartment.
Besonders bevorzugt ist eine Ausführungsform, die vorsieht, dass der Hinterschnitt von außen zugänglich an einem durch das Andockelement gebildeten Stutzen auf der Einlassöffnung gebildet ist. Über den von außen zugänglichen Hinterschnitt können sehr einfach Befestigungselemente des Staubsaugers von außen in den Hinterschnitt am Stutzen des Andockelements eingreifen und den Stutzen mit der Einlassöffnung des Filterbeutels sicher positionieren. Hierdurch wird der Staubbeutel einfach durch von außen an das Andockelement angreifende und in den Hinterschnitt eingreifende Befestigungselemente des Staubsaugers sicher im Staubraum festgelegt.An embodiment is particularly preferred which provides that the undercut is formed on a socket formed by the docking element on the inlet opening so that it is accessible from the outside. Fastening elements of the vacuum cleaner can very easily engage from the outside in the undercut on the connection piece of the docking element via the undercut accessible from the outside and securely position the connection piece with the inlet opening of the filter bag. As a result, the dust bag is securely fixed in the dust chamber simply by fastening elements of the vacuum cleaner engaging the docking element from the outside and engaging in the undercut.
Eine besonders vorteilhafte Ausführung der Erfindung bezieht sich darauf, dass der Hinterschnitt von innen zugänglich in einem durch das Andockelement gebildeten Stutzen an der Einlassöffnung gebildet ist. Über den von innen zugänglichen Hinterschnitt können sehr platzsparend Befestigungselemente des Staubsaugers von innen in den Hinterschnitt am Stutzen des Andockelements eingreifen und den Stutzen mit der Einlassöffnung des Filterbeutels sicher positionieren. Hierdurch wird der Staubbeutel einfach durch von innen an das Andockelement angreifende und in den Hinterschnitt eingreifende Befestigungselemente des Staubsaugers sicher im Staubraum festgelegt.A particularly advantageous embodiment of the invention relates to the fact that the undercut is formed in a socket formed by the docking element at the inlet opening so that it is accessible from the inside. Via the undercut, which is accessible from the inside, fastening elements of the vacuum cleaner can engage from the inside in the undercut on the connection piece of the docking element in a very space-saving manner and securely position the connection piece with the inlet opening of the filter bag. As a result, the dust bag is securely fixed in the dust chamber simply by means of fastening elements of the vacuum cleaner which act on the docking element from the inside and engage in the undercut.
Eine besonders vorteilhafte Ausführung der Erfindung sieht daher vor, dass das Andockelement einen Verdrehschutz aufweist. Über den Verdrehschutz kann sichergestellt werden, dass das bevorzugt rotationsymmetrische Andockelement sich nicht in den Befestigungselementen des Staubsaugers verdreht.A particularly advantageous embodiment of the invention therefore provides that the docking element has anti-twist protection. The twist protection can be used to ensure that the preferably rotationally symmetrical docking element does not twist in the fastening elements of the vacuum cleaner.
Eine vorteilhafte Ausführung der Erfindung sieht vor, dass der Verdrehschutz durch eine halbkreisförmige Einbuchtung gebildet ist. Mit der halbkreisförmigen Einbuchtung ist ein besonders einfacher Verdrehschutz für das Andockelement gegeben. Die Befestigungselemente des Staubsaugers verfügen vorteilhafterweise über einen in die halbkreisförmige Einbuchtung eingreifenden Vorsprung. So kann das Andockelement bei Aufnahme in den Befestigungselementen des Staubsaugers wirksam gegen eine Verdrehung gesichert werden, sodass der Staubbeutel optimal im Staubraum des Staubsaugers positioniert bleibt.An advantageous embodiment of the invention provides that the anti-twist protection is formed by a semicircular indentation. The semicircular indentation provides particularly simple anti-twist protection for the docking element. The fastening elements of the vacuum cleaner advantageously have a projection which engages in the semicircular indentation. The docking element can thus be effectively secured against twisting when it is received in the fastening elements of the vacuum cleaner, so that the dust bag remains optimally positioned in the dust compartment of the vacuum cleaner.
Besonders vorteilhaft ist eine Ausführungsform, die vorsieht, dass der Andockring aus zwei den Hinterschnitt bildenden Teilringen zusammengesetzt ist. Über die zwei den Hinterschnitt bildenden Teilringe ist eine besonders einfache Fertigung des Hinterschnitts, insbesondere im Spritzguss, bevorzugt aus Kunststoff, möglich. Die zwei Teilringen können besonders leicht aus einer sehr einfach aufgebauten Spritzgussform entformt werden.An embodiment which provides that the docking ring is composed of two partial rings forming the undercut is particularly advantageous. A particularly simple production of the undercut, in particular by injection molding, preferably from plastic, is possible via the two partial rings forming the undercut. The two partial rings can be demolded particularly easily from a very simply constructed injection mold.
Eine vorteilhafte Ausgestaltung der Erfindung sieht vor, dass die Teilringe über ein Filmscharnier verbunden sind, wobei das Filmscharnier die Teilringe zum Zusammenklappen des Andockrings passend positioniert. Über das Filmscharnier können die beiden Teilringe des Andockrings verbunden über das Filmscharnier in einem Spritzvorgang in einem Spritzwerkzeug im Spritzgussverfahren bevorzugt aus Kunststoff hergestellt werden. Anschließend müssen die Teilringe einfach in nur einem Montageschritt an dem Filmscharnier zur Bildung des Hinterschnitts im Andockring zusammengeklappt und zusammengerückt werden. Da die Teilringe bereits über das Filmscharnier passend zueinander positioniert sind, kann der Montageschritt auch von einem einfachen Automaten übernommen werden, sodass ein hoher Grad an Automatisierung bei der Fertigung des Staubbeutels erreicht wird.An advantageous embodiment of the invention provides that the ring parts are connected via a film hinge, with the film hinge positioning the ring parts appropriately for folding the docking ring together. The two partial rings of the docking ring, connected via the film hinge, can be produced via the film hinge in an injection molding process in an injection mold using the injection molding process, preferably from plastic. The partial rings then simply have to be folded together and pushed together in just one assembly step on the film hinge to form the undercut in the docking ring. Since the partial rings are already positioned to match one another via the film hinge, the assembly step can also be taken over by a simple machine, so that a high degree of automation is achieved in the production of the dust bag.
Gemäß einer vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass die Einlassöffnung durch mindestens einen schlitzförmigen Einschnitt in das Material des Filterbeutels gebildet ist. Der schlitzförmige Einschnitt in das Material des Filterbeutels ersetzt die flächige Ausstanzung des Filterbeutel-Materials zur Herstellung der Einlassöffnung. Während eine flächige Einlassöffnung in Filterbeuteln heute üblicherweise durch eine Klappe an der die Einlassöffnung umgebenden Haltevorrichtung verschlossen wird, kann bei dem erfindungsgemäßen Staubbeutel auf eine solche Klappe verzichtet werden. Über den schlitzförmigen Einschnitt kann der durch den Andockring der Haltevorrichtung geführte Einlassstutzen des Staubsaugers in den Filterbeutel vordringen, sodass der staubbeladende Luftstrom des Staubsaugers in den Staubbeutel geleitet werden kann. Bei Wechsel eines vollen Staubbeutels wird der Einlassstutzen des Staubsaugers aus dem Staubbeutel entfernt. Üblicherweise verschließt dann eine Klappe die flächige Einlassöffnung, damit kein Staub bei der Handhabung des vollen Staubbeutels austreten kann. Auf diese Art von kompliziertem Hygieneverschluss kann mit dem schlitzförmigen Einschnitt in das Material des Staubbeutels verzichtet werden. Das den Schlitz der Einlassöffnung umgebende Material des Filterbeutels rutscht beim Verlassen des Einlassstutzens zurück und verschließt den Schlitz der Einlassöffnung wieder so weit, dass ein Staubaustritt mit diesen einfachen Mitteln wirksam verhindert werden kann.According to an advantageous embodiment of the invention, it is provided that the inlet opening is formed by at least one slit-shaped incision in the material of the filter bag. The slit-shaped incision in the material of the filter bag replaces the flat punching out of the filter bag material to create the inlet opening. While a flat inlet opening in filter bags is nowadays usually closed by a flap on the holding device surrounding the inlet opening, such a flap can be dispensed with in the dust bag according to the invention. The slot-shaped incision can be made through the docking ring of the holding device Push the vacuum cleaner inlet nozzle into the filter bag so that the dust-laden air flow from the vacuum cleaner can be directed into the dust bag. When changing a full dust bag, the inlet nozzle of the vacuum cleaner is removed from the dust bag. A flap then usually closes the flat inlet opening so that no dust can escape when handling the full dust bag. This type of complicated hygienic closure can be dispensed with with the slit-shaped incision in the material of the dust bag. The material of the filter bag surrounding the slit of the inlet opening slides back when it leaves the inlet connection and again closes the slit of the inlet opening to such an extent that dust can be effectively prevented from escaping with these simple means.
Gemäß einer vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass der Einschnitt in das Material des Filterbeutels für die Einlassöffnung u-förmig, kreuzförmig, sternförmig, gerade oder kreislinienförmig ausgebildet ist. Die Einlassöffnung soll somit nicht kreisrund komplett ausgestanzt werden, wie bei heutigen Staubbeuteln üblich, sondern bevorzugt als ein u-förmiger Schlitz in das Material des Filterbeutels geschnitten werden. Hierdurch entsteht vorteilhafterweise ein Vlieslappen im Bereich der Einlassöffnung. Dieser Vlieslappen sorgt dann dafür, dass beispielsweise beim Fallen des Staubbeutels in den Mülleimer keine Staubwolke entsteht durch aus der Einlassöffnung austretenden Staub beim Auftreffen des Staubbeutels auf dem Eimergrund. Neben dem u-förmigen Einschnitt sind auch weitere Formen möglich, die den Austritt von Staub aus der Einlassöffnung wirksam verhindern können und dennoch ein leichtes Eintauchen des Einlassstutzens des Staubsaugers ermöglichen.According to an advantageous embodiment of the invention, it is provided that the incision in the material of the filter bag for the inlet opening is U-shaped, cross-shaped, star-shaped, straight or circular. The inlet opening should therefore not be completely punched out in a circle, as is usual with today's dust bags, but should preferably be cut as a U-shaped slit in the material of the filter bag. This advantageously creates a fleece flap in the area of the inlet opening. This fleece flap then ensures that, for example, when the dust bag falls into the trash can, no cloud of dust is created by dust escaping from the inlet opening when the dust bag hits the bottom of the bucket. In addition to the U-shaped incision, other shapes are also possible, which can effectively prevent the escape of dust from the inlet opening and still allow the inlet connection piece of the vacuum cleaner to be easily immersed.
