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, wherein an inlet opening for receiving a dust-laden air flow of the vacuum cleaner is let into the holding device, wherein a filter bag made of an air-permeable material and open to the inlet opening is arranged on the holding device, wherein the material of the filter bag is designed to filter the dust from the air flow as the air flow passes through.
  • the inlet opening is regularly provided with a seal that guides the dust bag towards an inlet nozzle of the vacuum cleaner that is immersed in the inlet opening. vacuum cleaner.
  • the holding plate usually offers a handle that the user can use to handle the dust bag when changing the bag.
  • the ITVI20120079 A1 discloses a dust bag for a vacuum cleaner with a nozzle-shaped connector, which forms undercuts on the outside of the connector for locking the dust bag to a holding plate.
  • the DE 69822894 D1 and EN 69029843 T2 disclose dust bags for vacuum cleaners with a holding plate which is designed to receive an undercut from the suction nozzle of the vacuum cleaner.
  • a dust bag with the features of claim 1. Because the holding device is designed as a docking element that surrounds the inlet opening, the docking element forming an undercut for fastening the dust bag in a vacuum cleaner, a particularly simply constructed dust bag can be created that offers a simple and secure fastening option in the dust chamber of a vacuum cleaner.
  • the dust bag can be firmly and tightly fastened to an inlet nozzle of the vacuum cleaner that dips into the inlet opening via the surrounding docking element.
  • fastening elements of the vacuum cleaner can simply engage in the undercut on the surrounding docking element. This allows the simply constructed docking element, which surrounds the inlet opening of the filter bag, to be positioned securely in the dust chamber.
  • the simple structure of the holding device significantly reduces the waste generated by the dust bag when changing the dust bag.
  • the docking element preferably completely surrounds the inlet opening of the dust bag. In an alternative embodiment, however, it is also conceivable for the docking element to only partially surround the inlet opening of the dust bag.
  • the holding device is preferably simply welded to the material of the filter bag.
  • the holding device described makes it possible to manufacture the entire dust bag, including the simple holding device, from a single material.
  • a polypropylene-based nonwoven fabric is suitable for
  • the filter bag with a simple holding device can also be made of polypropylene. This also makes recycling the dust bag much easier.
  • 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 only be partially surrounded by the docking ring segment.
  • An embodiment is particularly preferred which provides that the undercut is formed on a nozzle formed by the docking element on the inlet opening and is accessible from the outside.
  • Fastening elements of the vacuum cleaner can very easily engage from the outside into the undercut on the nozzle of the docking element via the undercut which is accessible from the outside and securely position the nozzle 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 which engage from the outside on the docking element and engage in the undercut.
  • the undercut is accessible from the inside in a nozzle formed by the docking element at the inlet opening.
  • the undercut which is accessible from the inside, allows fastening elements of the vacuum cleaner to engage from the inside in the undercut on the nozzle of the docking element in a very space-saving manner and Securely position the nozzle with the inlet opening of the filter bag.
  • This means that the dust bag is securely fixed in the dust chamber by means of the vacuum cleaner's fastening elements that engage 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 an anti-twist device.
  • the anti-twist device can 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 recess.
  • the semicircular recess provides particularly simple anti-twist protection for the docking element.
  • the fastening elements of the vacuum cleaner advantageously have a projection that engages in the semicircular recess. This means that the docking element can 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 chamber of the vacuum cleaner.
  • a particularly advantageous embodiment is one in which the docking ring is composed of two partial rings forming the undercut.
  • the two partial rings forming the undercut enable particularly simple production of the undercut, in particular by injection molding, preferably from plastic.
  • the two partial rings can be removed particularly easily from a very simply constructed injection mold.
  • An advantageous embodiment of the invention provides that the partial rings are connected via a film hinge, whereby the film hinge positions the partial rings appropriately for folding the docking ring.
  • the two partial rings of the docking ring can be connected via the film hinge in an injection molding process in an injection molding tool, preferably made of plastic.
  • the partial rings then simply have to be folded 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 appropriately to one another via the film hinge, the assembly step can also be carried out 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 slot-shaped cut in the material of the filter bag.
  • the slot-shaped cut 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 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 inlet nozzle of the vacuum cleaner which is guided through the docking ring of the holding device, can penetrate into the filter bag via the slot-shaped incision, so that the dust-laden air flow of the vacuum cleaner can be directed into the 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 hygiene closure can be dispensed with with the slot-shaped incision in the material of the dust bag.
  • the material of the filter bag surrounding the slot of the inlet opening slides back when leaving the inlet nozzle and closes the slot of the inlet opening again to such an extent that dust escape can be effectively prevented with these simple means.
  • the cut 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 punched out completely 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 that can effectively prevent dust from escaping from the inlet opening and still allow the inlet nozzle of the vacuum cleaner to be easily immersed.
  • FIG. 1 A dust bag is shown schematically with the reference number 1.
  • the illustration according to Figure 1 shows a dust bag 1 according to the invention for a vacuum cleaner with a holding device 2 for fastening in a dust chamber of the vacuum cleaner.

  • the surrounding docking ring 6 enables the dust bag 1 to be attached firmly and tightly to an inlet nozzle of the vacuum cleaner that extends into the inlet opening 3.
  • the inlet opening 3 is also formed by a slot-shaped incision 13 in the material of the filter bag 5. This slot-shaped incision 13 in the material of the filter bag 5 replaces a conventional flat punching out of the filter bag material to produce the inlet opening 3.
  • the inlet nozzle of the vacuum cleaner which is guided through the docking ring 6 of the holding device 2, can penetrate into the filter bag 5 through the slot-shaped incision 13, so that the dust-laden air flow 4 of the vacuum cleaner can be guided into the dust bag 1. If the full dust bag 1 is changed, the inlet nozzle of the vacuum cleaner is removed from the dust bag 1, and the material of the filter bag 5 surrounding the slot 13 of the inlet opening 3 slides back when leaving the inlet nozzle and largely closes the slot 13 of the inlet opening 3 again, so that dust can be effectively prevented from escaping with these simple means.
  • the incision 13 in the material of the filter bag 5 is straight. In other embodiments, the incision 13 can also be U-shaped, cross-shaped, star-shaped or circular. In all cases, the inlet opening 3 is not flat, but rather cut in the material of the filter bag 5 like a slit.
  • the Figure 2 shows a detailed view of the holding device according to Figure 1 .
  • the undercut 7 is formed in a nozzle 8 formed by the docking ring 6 at the inlet opening 3 and is accessible from the inside.
  • the undercut 7, which is accessible from the inside, enables fastening elements of the vacuum cleaner to engage from the inside in the undercut 7 on the nozzle 8 of the docking ring 6 in a very space-saving manner. This connects the nozzle 8 to the inlet opening 3 of the filter bag 5 ( Fig.1 ) safely in the dust compartment of the with the dust bag 1 ( Fig.1 ) equipped vacuum cleaner.
  • the dust bag 1 ( Fig.1 ) is securely fixed in the dust chamber simply by fastening elements of the vacuum cleaner that engage the docking ring 6 from the inside and engage in the undercut 7.
  • the immersed inlet nozzle of the vacuum cleaner can be provided with a seal that seals against the docking ring 6.
  • the anti-twist device 9 on the docking ring 6 can also be seen, which is designed as a semicircular indentation.
  • the fastening elements of the vacuum cleaner advantageously have a projection that engages in the semicircular indentation 9. In this way, 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.
