Definitions

  • the invention relates to an electric vacuum cleaner with a receiving chamber for a dust bag with a carrier plate, which has a textile cover on the outside and a grid structure on the inside, an electret filter being arranged between the grid structure and the textile cover and an upper support frame being formed for the carrier plate of the dust bag.
  • Such an electric vacuum cleaner with a receiving chamber for a dust bag provided with a carrier plate is known for example from DE-OS 39 11 580, here an electric vacuum cleaner with an associated dust bag is shown, which after opening and disconnecting a nozzle connection connection from a receiving chamber is removable.
  • the dust bag lies with its carrier plate in an upper support frame of the receiving chamber.
  • the reception chamber is not described in more detail in the aforementioned application.
  • those are known which have an outside textile cover and an inside grid structure, an electret filter being arranged between the grid structure and the textile cover. If it is not handled properly, especially if the dust bag is not properly inserted into the receiving chamber or if an incorrectly fitting dust bag is used, the electret filter may become dirty over time, which is not desirable for hygienic reasons.
  • EP-A-0 244 589 shows a receiving chamber with a lattice structure and an electrically charged filter.
  • the object of the present invention is to provide a generic electric vacuum cleaner with a receiving chamber for a dust bag with a carrier plate handling technology and in terms of improved hygiene cheaper.
  • an electric vacuum cleaner is designed with a receiving chamber for a dust bag with a carrier plate, which is improved particularly in terms of handling technology and above all with regard to increased hygiene.
  • This is achieved in that the lattice structure is removably connected to the support frame, that the electret filter is firmly fitted to the lattice structure or the support frame and that the support frame is snap-connected to a holding frame to which the textile cover is attached, the solution being that Snap connection an elastic deflection of sections of the support frame to the inside is required.
  • the receiving chamber is formed in two parts, one part having a holding frame to which the textile cover on the outside is fastened and the other part having the supporting frame with the lattice structure connected to it, to which the electret filter is attached.
  • the electret filter can thus be removed from the receiving chamber in the simplest manner and cleaned or replaced.
  • the locking connection between the holding frame and the support frame of the receiving chamber is released by an elastic deflection of sections of the support frame inwards, after which the support frame together with it Grid structure and the electret filter can be lifted off the holding frame.
  • the support frame can be provided in a known manner on the inside of its support surface for the carrier plate of the dust bag with orientation features in the form of niches or the like, in order to ensure that the dust bag is correctly positioned within the support frame.
  • it is provided in a support frame which has a substantially rectangular outline that latching projections are arranged on the longitudinal sides, preferably approximately in the center, on the support frame.
  • the sections of the support frame in the area of the latching projections being elastic, the electrical filter attached to the support frame and the lattice structure can thus be removed from the receiving chamber. It is particularly advantageous here if two essentially opposite locking projections are provided. This results in a one-hand operation, with the two opposing locking projections of the support frame being deflected inwards with one hand, whereby the locking connection to the holding frame is released. Furthermore, the locking connection is optimized such that the locking projections are dovetail-shaped. However, configurations are also conceivable in which the latching projections are, for example, trapezoidal or the like.
  • the latching connection between the support frame and the holding frame can be provided with simple means in that the latching connection is formed Locking receptacles are provided in the holding frame, which locking receptacles have undercuts corresponding to the locking projections and are open at the top.
  • the dovetail-shaped locking projections are advantageously arranged on the outside of the support frame and engage in correspondingly shaped locking receptacles in the region of the holding frame. Due to the dovetail or trapezoidal design, with the narrow side of the dovetail or the trapezoid pointing upwards, pulling the support frame out of the holding frame upwards is counteracted without prior deflection of the latching projections towards the inside.
  • the support frame Only when the associated locking projections with their locking receptacles are correctly assigned can the support frame be inserted into the holding frame, the locking projections entering the respective locking receptacles. According to this, the dust bag with its carrier plate can also be in the correct position be used. However, if the support frame is inserted incorrectly, at least one locking projection cannot enter the locking receptacle of the holding frame facing it, so that this section of the support frame remains deflected inwards. Due to this deflection, the dust bag with its carrier plate cannot be inserted into the support frame.
  • the electric vacuum cleaner 1 shown in Figure 1 is designed as a handheld device. It has a housing 2, to which there is a handle 3 with a handle 4 at the end. In the transition area between handle 4 and handle 3 there is an on / off switch 5.
  • the electrical cable connection is identified by the number 6.
  • the housing 2 is divided into a motor housing 7 and a receiving chamber 8 extending thereover for receiving a dust bag 9.
  • the motor fan is not shown in detail in the drawing.
  • the dust bag 9 On the side facing the motor housing 7, the dust bag 9 has a carrier plate 10, which is in connection piece connection to a blower air duct.
  • the underside of the motor housing 7 merges into a pipe coupling 11 which establishes the air flow connection to a suction nozzle 12.
  • the suction nozzle 12 can be a so-called suction / brush nozzle, which contains a brush roller in the nozzle mouth, which is set in rotation by a separate drive.
  • the blower motor works from the bottom up and consequently presses the dust air into the dust bag 9, which is arranged above the motor housing 7.
  • the cross section of the housing 2 is of a long rectangular design with slightly bulging broad sides and narrow sides.
  • the vacuum cleaner can be seen from the broad side.
  • the receiving chamber 8 shown specifically in FIG. 2 is essentially of two parts.
  • a holding frame 13 is provided, on which an outside textile cover 14 is attached.
  • a support frame 15 lying in the holding frame 13 is provided, which has a basket-like grid structure 16 on the underside.
  • This lattice structure 16 extends in the installed position according to FIG. 2 in the same direction and in almost the same length as the textile covering 14 and serves to stiffen the latter.
  • the grid structure 16 is also completely covered with an electret filter 17, the electret filter 17 being fastened in the region of the support frame 15 in a groove 18 provided on the underside of the frame. Both the lattice structure 16 and the electret filter 17 drawn over it form a bottom 34.
  • the holding frame 13 corresponding to the motor housing has a handle 19 on the narrow side facing away from the textile covering 14, by means of which the receiving chamber 8 can be pivoted out of the working position into a filter removal position according to the dash-dotted representation in FIG. 1.
  • a locking connection is to be released by means of the handle 19 on the motor housing 7.
  • the holding frame 13 accordingly has a folding axis 20 which is held between two bearing eyes, also not shown, on the motor housing side.
  • the holding frame 13 On the two long sides 21, the holding frame 13 has a dovetail-shaped snap-in receptacle 22 in the center, the arrangement being such that the broad side of the dovetail points in the direction of the textile cover 14 and the snap-in receptacle 22 in the region of the narrow side of the dovetail is open to the edge, ie to the the side of the holding frame 13 facing away from the textile covering 14 is open. In relation to FIG. 2, this means that the catch receptacle 22 is open at the top.
  • the holding frame 13 is smooth on the inside.
  • the support frame 15 is adapted to the holding frame 13 in cross-section, so that it can lie in the holding frame 13 according to FIG.
  • the support frame 15 has on its longitudinal sides 23 approximately dovetail-shaped locking projections 24 in the middle, the dovetail shape of which corresponds to that of the respective locking receptacle 22 of the holding frame 13.
  • the support frame 15 is elastic in the region of its long sides 23.
  • On the inside of the edge, the support frame 15 has an edge step 25 at a distance of approximately 15 mm from the upper edge.
  • This edge step is provided with orientation features in the form of niches 26 on the two narrow sides, with a niche 26 on the narrow side of the edge step facing the handle 19 of the holding frame 13 25 are arranged in the center and two niches on the narrow side facing the folding axis 20 on both sides of an imaginary longitudinal center line of the support frame 15.
  • locking latches 27 are provided on the inner sides of the longitudinal sides 23 upwards.
  • the basket-like lattice structure 16 is formed on the underside of the support frame 15 along its edge. As already mentioned, this lattice structure 16 is spanned by the electret filter 17, which is fastened in the region of its upper edge in a groove 18 of a collar 28 which extends underneath the support frame 15.
  • the dust bag 9 to be inserted into the receiving chamber 8 has, as already mentioned, a carrier plate 10, the general outline of which corresponds to the cross-sectional shape of the support frame 15.
  • the carrier plate 10 is provided with a circular opening 30 which, in the installed position according to FIG. 2, is arranged in the region facing the handle 19 of the receiving chamber 8.
  • a nozzle enters, via which dust and dirt particles are conveyed into the dust bag 9.
  • the latter is provided with an annular lip seal 31.
  • the carrier plate 10 is provided approximately centrally each with a gripping opening 32, which is chamfered and is designed to be open toward the corresponding inner wall of the support frame 15.
  • the dust bag 9 can be gripped comfortably by means of a clamping handle in the central zone of the carrier plate 10 and lifted out of the receiving chamber 8 or out of the basket-like lattice structure 16.
  • the carrier plate 10 is further provided with trapezoidal projections 33 corresponding to the niches 26 of the support frame 15. In the installation position according to FIG. 3, the dust bag 9 lies with its carrier plate 10 in the support frame 15, the carrier plate 10 being supported on the edge step 25 and being engaged behind by the latching lugs 27.
  • the projections 33 of the support plate 10 lie in the niches 26 of the support frame 15 assigned to them.
  • the electric vacuum cleaner 1 can be provided in the area of the transition from the motor housing 7 to the receiving chamber 8 with a fuse which consists, for example, of a sprung finger or the like when the receiving chamber 8 is pivoted back into the operating position according to FIG 10 of the dust bag 9 is applied, whereby locking projections are displaced such that they can enter the gripping openings 32 of the support plate 10.
  • a fuse which consists, for example, of a sprung finger or the like when the receiving chamber 8 is pivoted back into the operating position according to FIG 10 of the dust bag 9 is applied, whereby locking projections are displaced such that they can enter the gripping openings 32 of the support plate 10.
  • the said finger is accordingly not acted upon.
  • the pivotable projections of the motor housing 7 remain in a locked position in which the receiving chamber 8 is prevented from pivoting into the closed position. It is thus ensured that the Receiving chamber 8 a dust bag 9 is always inserted on the motor housing 7.
  • the electret filter 17 can become dirty.
  • the support frame 15 carrying this electret filter 17 via the lattice structure 16 can be pulled out of the holding frame 13 by deflecting the locking projections 24 in the region of the elastically designed longitudinal sides 23 in the direction of the arrow P (see FIG. 5 ).
  • this is only possible when the dust bag 9 is removed from the receiving chamber 8, since otherwise the carrier plate 10 prevents the longitudinal sides 23 from deflecting inwards.
  • the support frame 15 can now be pulled upward out of the holding frame 13 in the direction of arrow Z (see FIG. 6). As a result, the electret filter 17 pulled over the lattice structure 16 is exposed. This can then be cleaned or replaced.
  • the insertion of the dust bag or the insertion of the carrier plate 10 of the dust bag 9 must be in the correct position, since otherwise when the receiving chamber 8 is pivoted back into the operating position according to FIG. 1, the connecting piece on the motor housing side cannot enter the opening 30 of the carrier plate 10. Because of this requirement, it is now also necessary to insert the support frame together with the grid structure 16 and the electret filter 17 in the correct position in the holding frame 13. This can be done, for example be realized that the locking projections 24 and the associated locking receptacles 22 are shaped differently or are arranged off-center.
  • the electric vacuum cleaner 1 can be provided with a safety device which prevents the receiving chamber 8 from closing without the dust bag 9 inserted.
