Definitions

  • the invention relates to a vacuum cleaner with a chamber for receiving a dust filter bag, the chamber being closable with a lid and an actuating projection for actuating a dust filter bag closure being formed on the underside of the lid, the actuating projection also being pivotally connected to the lid.
  • a vacuum cleaner designed in this way is known, for example, from a not previously published German patent application by the applicant (file number 196 13 511.7).
  • the content of this patent application is hereby incorporated in full into the disclosure of the present invention, also for the purpose of including features of this application in claims of the present invention.
  • a vacuum cleaner is specified, the chamber for receiving a dust filter bag can be closed by a lid, a cover-side actuating projection displacing a closure element of the dust filter bag in the course of the closing process in such a way that the suction opening of a holding plate on the dust filter bag side is opened. Opening the filter bag chamber by means of the cover causes the closure element to be displaced back into a closed position of the suction opening of the holding plate via the actuating projection.
  • the actuating projection has a foot for support on a support surface and that the foot is designed for rolling on the support surface.
  • a part, preferably the major part, of the applied forces is derived via the foot into a support surface.
  • This support surface can be, for example, a surface formed in the chamber receiving the dust filter bag.
  • the closure When the closure is designed in the form of a slide arranged between two layers of a holding plate, the influence of frictional forces and the bending load on the slide are kept low due to this configuration. Furthermore, it proves to be advantageous that, in the course of the pivoting of the lid to close or open the vacuum cleaner, supporting sliding of the foot on the supporting surface is facilitated by rolling off the foot. As a result, the forces introduced in particular in the course of a closing movement of the vacuum cleaner cover are kept low.
  • the cover is a drag cover. Such a drag cover is from the beginning not previously known patent application of the applicant known.
  • the pivot axis of the drag cover is offset, but is assigned to run parallel to the chamber axis. It is essential that the actuating projection is arranged pivotably on this drag cover.
  • An embodiment is preferred in which the drag cover is completely hidden from view in a coaxial length of the vacuum cleaner housing and filter chamber, ie in the closed position of the vacuum cleaner.
  • Such a drag lid preferably has a suction nozzle passing through the suction opening of the dust filter bag in the closed position of the vacuum cleaner, ie in its operating position.
  • the support surface is formed by a dust filter bag holding plate.
  • the latter also preferably has the slide mentioned above for forming the dust filter bag closure.
  • the forces exerted on the foot are introduced into stable areas of the dust filter bag holding plate.
  • the slide closing the suction opening is arranged outside this support surface area, so that the forces introduced via the attachment foot have no influence on the displaceability of the closure.
  • the foot is formed in a juxtaposition to the actuating projection. This results in a support surface on the side of the dust filter bag closure, which support surface either on the housing side or, as is preferred, on the holding plate side is trained.
  • the foot is arranged in a row behind the actuating projection.
  • the attachment foot can be arranged in relation to a closing movement of the vacuum cleaner housing in advance of the actuation projection, the non-loading of the dust filter bag closure by the attachment foot being ensured by maintaining a minimum distance between the actuation projection and the attachment foot.
  • the latter only acts on the support surface provided for this purpose.
  • the mounting foot has a mounting roller. This placement roller is arranged so that it derives the forces acting on the support surface at least over the entire closing or opening process of the dust filter bag closure.
  • the actuating projection Due to the pivotable mounting of the actuating projection on the lid, for example on the drag lid, the actuating projection performs a movement along the holding plate while taking the closure with the opening or closing of the dust filter bag closure, which at the same time causes the foot to move on the supporting surface has the consequence.
  • the arrangement of a placement roller reduces the frictional forces to a minimum. Furthermore, due to this configuration, any unevenness or damage to the supporting surface, in particular in the case of a holding plate made, for example, of a cardboard / paper material, does not lead to a malfunction, since the mounting foot provided with a roller can easily slide over these defects.
  • a major advantage here is that a roller axis runs essentially parallel to the support surface. It is further proposed that two placement rollers are provided and each laterally of the actuating projection are arranged. This results in two support surfaces formed on both sides of the dust filter bag closure, preferably in the area of the holding plate.
  • the invention further relates to a vacuum cleaner of the type in question, the actuating projection being arranged to be deflectable against a spring force.
  • a vacuum cleaner of the type in question the actuating projection being arranged to be deflectable against a spring force.
  • actuating projection is displaceably mounted against the force of a molded spring which is designed in the shape of a part of a circle, the displaceability of the actuating projection being provided by a rail-like guide.
  • a registration projection be formed on the cover, which secures the actuation projection with regard to a complete opening of the dust filter bag closure.
  • the registration projection can be used to determine whether the locking slide has been completely moved into its end position. If this is not the case, this can lead to malfunctions. For example, the closure slide can still partially in the area of the suction opening protrude, which would lead to a collision with the intake manifold in the course of a further closing movement of the system. After a complete opening of the closure, the registration projection enters a registration opening formed in the area of the actuation projection.
  • the registration projection be arranged on the underside of the cover in such a way that, when the cover is closed, the cover protrudes into a recess on the rear of the actuation projection with respect to the spring mobility of the actuation projection.
  • the registration projection thus on the one hand relieves the pressure on the spring acting on the actuation projection and on the other hand forces the actuation projection into an end position defining the open position of the dust filter bag closure.
  • two registration projections are formed, which each move into a separate recess of the actuating projection.
  • the engagement force of the actuating projection in the closure is kept low by the spring mobility over the entire closure path, which leads to a low bending load on the slide.
  • the spring element acting on the actuating projection is advantageously designed as an integrated ring spring element.
  • the invention further relates to a vacuum cleaner of the type in question, wherein the actuating projection is arranged on a pivot plate holding the latter, the pivot plate is pivotally connected to the cover about an articulated axis and the pivot plate can be folded against the force of a spring on the cover, whereby the spring has a spring leg supported on the cover.
  • a drag cover of the type mentioned is specified, which is connected in the region of its free end via a hinge axis to a swivel plate. The latter in turn carries the actuating projection in its free end region.
  • a spiral spring is arranged, the first spring leg of which is supported against the underside of the cover and the second spring leg of which is supported against the swivel plate.
  • the swivel plate can be folded against the spring cover against the spring force, the folded position corresponding to the operating position of the vacuum cleaner.
  • the swivel plate swivels away from the drag cover due to the spring action.
  • a plastic-coated tape stretched stretched.
  • This defined swivel end position is necessary in order to ensure that the driving device of the dust filter bag closure is found automatically by the actuating projection when the drag cover together with the swivel plate is swiveled in during the closing of the system.
  • the spring leg first spring leg
  • the end of the spring leg moves along the end of the stop with a folding movement on the underside of the lid.
  • the free end of the spring leg is preferably guided on a slideway on the underside of the cover, the shape of the slideway being formed such that the closing force introduced into the dust filter bag closure by the actuating projection is relatively high even in the end position, ie in the closed position of the closure slide.
  • This configuration also makes it possible for the static forces in the closed system, ie when the swivel plate is folded onto the cover, to be very low.
  • the stop-limited position of the spring leg corresponds to the spread end position of the swivel plate and cover.
  • the leg rotation center of the spring leg for example the winding package of a spiral spring, is arranged in a region of the swivel plate which executes a movement relative to the cover.
  • the stop is arranged on the underside of the cover and away from the hinge axis.
  • the swivel plate folds against the lid against the spring force.
  • the free end of the spring leg supported on the underside of the cover moves in the direction on the hinge axis, with the spring leg aligned almost parallel to the cover after the closure has been closed and the plate has been completely folded down.
  • the swivel plate expands from the cover with spring support, the free end of the spring leg acting on the underside of the cover moving away from the region of the articulated axis and moving in the direction of the cover-side stop.
  • the stop position is defined by this stop.
  • the stop is designed as a catch hook.
  • the spring leg has an eyelet section at the end and that the catch hook engages in the eyelet when the swivel plate is in the folded-down position. It thus follows that the catch hook secures the swivel end position of the swivel plate and cover by engaging in the eyelet.
  • the spring between the swivel plate and cover thus has a double function. On the one hand, it causes the spring-assisted spreading of the swivel plate and cover.
  • the length of the spring leg acting on the underside of the cover and the engagement of the catch hook in the end-side eyelet form a holding element securing the pivoting position, thus replacing the ribbon mentioned in the prior art.
  • the closing force applied to the dust filter bag closure when the system is opened remains constant over the entire displacement path. This results in a secure closing or opening of the closure.
  • the closing movement of the dust filter bag closure is supported by the spring-assisted spreading of the swivel plate from the cover, with the free end region of the one spring leg sliding on the underside of the cover along a jump-like elevation in an end region of the spreading movement the slideway moves, which further increases the spreading force of the swivel plate and cover.
  • FIG. 2 shows a side view of the housing 2 and filter chamber 7, a position of the filter chamber pivoted through 180 ° to expose the same. It can be seen that the filter chamber 7 is pivotally attached to the vacuum cleaner housing 2 via a folding axis 8.
  • the filter chamber 7 shown in a top view in particular in FIG. 7 has an essentially rectangular opening cross section.
  • an axle mount 10 with front axle knuckles 11 is arranged on the outside of the filter chamber 7 on the housing. The latter are guided for pivoting the filter chamber 7 in appropriately aligned knuckle receptacles of the housing 2.
  • These steering knuckle receptacles are arranged in two mounting brackets 12 assigned to the end faces of the axle mount 10 to form the folding axis 8.
  • the housing 2 has a housing opening cross section which corresponds to the chamber opening when the vacuum cleaner is closed and which essentially corresponds to the cross section of the chamber opening.
  • the filter chamber 7 is sealingly connected to the housing 2, with a locking device being provided which is formed by a handle 14 having a locking lug 13 and by a locking receptacle 15 on the housing side.
  • Handle 14 and locking receptacle 15 are each in the area
  • the narrow side of the filter chamber 7 or housing 2 facing away from the folding axis 8 is arranged (cf. FIG. 2).
  • the filter chamber 7 which receives a dust filter bag 16 is formed in the form of a cassette-like, funnel-like plastic part, for example produced by the injection molding process, with a chamber opening 17 which is essentially delimited by the chamber wall 18.

  • All four layers of the holding plate 19 are of the same design, at least in relation to the outer contour. Only the layer arranged between the uppermost and the third layer is designed as a spacing layer for the layer forming the ceiling and serves to form a space which is closed on all sides and in which a space likewise preferably made of a cardboard / paper material Closure element V is slidably inserted. The latter serves to close the suction opening 22 before the dust filter bag 16 is removed from the filter chamber 7.
  • the closure element V is essentially composed of a closure plate 25 to be closed off the suction opening 22 and a slide handle 26 aligned in the longitudinal extent of the holding plate 19. The latter is arranged on the side of the closure plate 25 facing away from the narrow end region 21.
  • the holding plate 19 has a separate opening 27 in its uppermost position, which is elongated in rectangular shape in plan.
