A dust collecting bag is fixed to the holding plate, and the holding plate has the supply opening, preferably closeable, for dust-containing air flowing in the supply direction substantially perpendicular to the opening surface of the supply opening. In this case, further, a lower grip section of the holding plate is formed in front of the fixing surface of the dust collecting bag to the holding plate in the direction of supplying the dust-containing air, and the dust collecting filter bag for a vacuum cleaner is provided. It is about.

  The invention furthermore relates to a holding plate and a dust collecting bag fixed to the holding plate in a vacuum cleaner, in particular a motor-driven vacuum cleaner, optionally in the form of a self-propelled floor cleaning device. Wherein the holding plate has a supply opening, preferably closable, for dust-containing air flowing in the supply direction substantially perpendicular to the opening surface of the supply opening. Wherein the vacuum cleaner further comprises a filter chamber for receiving the dust filter bag, and a suction / blowing sleeve to which the mounted dust filter bag is connected. In addition, the filter chamber is provided with a closing cover having a fitting projection, which can be swung to remove and attach the dust collecting filter bag, in which case the closing of the closing cover is provided with the fitting projection. Collection It is possible only when the filter bag and cooperates relates particulate filter bag apparatus for a vacuum cleaner machine.

  The present invention relates to various aspects. In particular, the installation of a new unused dust filter bag in the filter chamber of the vacuum cleaner, and more preferably the removal of the particularly used dust filter bag from the filter bag chamber, is also comfortable for the user. Must be executable. Furthermore, the operation of the vacuum cleaner must ensure that the dust filter bag is fitted.

  For this purpose, firstly, with respect to the dust filter bag, the lower gripping section overlaps in the projection direction corresponding to the feeding direction with the part of the holding plate which forms or transitions to the fixed surface, in which case the lower It is designed such that an engagement space is formed between the side grip section and the part of the holding plate.

  The engagement space formed in the holding plate provides a convenient area for a user to grip the filter dust bag when the dust filter bag is installed in or removed from the filter chamber. The engagement space is formed in an area of the holding plate that is hygienic. Thus, correspondingly, for example, to carry a filled dust filter bag, it is possible to carry out the holding in a region remote in the supply direction.

  Furthermore, the engagement space is formed so as to open radially outward, with respect to an axis preferably through the center of the supply opening, wherein in the cross-section where the fixing surface is shown as a line, the engagement space is The holding plate is formed by a U-shaped region which opens outward in the radial direction.

  Here, the U-leg assigned to the inflow side is formed by a lower gripping section, while the facing U-leg forms or transitions to the fixing surface and is fixed radially outwardly with respect to the axis of the supply opening. Is formed by a portion of the holding plate connected to the holding plate. These U-legs preferably extend parallel to each other. An acute angle of 1-30 °, preferably 1-10 °, may be formed between these U-legs, in which case the engagement space is only from radially inward to radially outward. Instead, it may be expanded from the outside in the radial direction to the inside in the radial direction.

  The opening surface of the supply opening is preferably formed in a sealing area cooperating with a lid or the like in the closed position of the supply opening. Therefore, it is preferable that the supply opening is provided in a sealing surface formed in a cooperative area between the lid and the holding plate.

  The feed direction may be considered to be the same as the straight line that follows the center line of the suction / blowing sleeve on the vacuum cleaner side, passes through the center of the inlet opening and extends into the dust bag. In this regard, no closure lid is considered. The actual feed direction, which also takes into account the effect of the flow due to the closure lid, is close to this, but does not run linearly.

  The straight line indicating the feed direction forms an acute angle with respect to the cross section of the feed opening, in which the sealing surface is shown as a line, approximately perpendicular to the sealing surface, preferably between 30-90 °, in particular between 60-90 °. To extend.

  Furthermore, the engagement space of the holding plate is (again) open in the direction of the fitting projection, in which the fitting projection is U-shaped in cross section, in the closed position of the closing cover, with respect to the dust collecting filter bag device in the vacuum cleaner. It is used so that it can enter into the engagement space.

  Through the engagement projections, in cooperation with the engagement space, a correct positioning of the filter bag in the filter chamber is ensured. Furthermore, this cooperation ensures that the dust filter bag is mounted in the filter chamber. When the dust-collecting filter bag is not present, and thus not cooperating with the engagement space of the holding plate, preferably the fitting projection is locked against the region of the filter chamber, whereby in a preferred form, In this situation, closure of the filter chamber is not possible.

  Through the fitting projections inserted into the engagement space, the additional required holding of the dust-collecting filter bag in the filter chamber can also be achieved. Furthermore, in a preferred embodiment, the fitting projections act so that the holding plate is hermetically sealed in the area of the supply opening against the suction / blowing sleeve on the vacuum cleaner side.

  With respect to the central axis of the supply opening, which is shown as the center point in the plan view of the supply opening, the lower gripping section has at least a radius outside the area of attachment of the dust bag to the holding plate in the projection direction along the supply direction. At least a large part overlaps outward in the direction. Since the dust bag has a spacing with respect to the lower gripping section, regardless of the degree of filling of the dust bag, the engagement space exists without being influenced by the dust bag.

  Thereby, the engagement space is also available for holding the dust collecting filter bag hygienically and preferably, especially when removing the dust collecting filter bag from the filter chamber.

  The dust bag extends above the holding plate, in particular in order to support the dust bag in the upside-down arrangement of the dust bag in the filter chamber, and furthermore, in a fixed plane, with respect to the central axis of the supply opening. It is preferable that a part of the holding plate extends radially outward of a portion fixed to the holding plate.

  In a preferred embodiment, the distance between the lower gripping section and the fixing surface or the part of the holding plate which transitions to the fixing surface varies radially and / or circumferentially, which is especially true for the lower gripping section. And the portion of the holding plate that moves into the fixed plane. Thus, the mutually facing surfaces of the lower gripping section and the portion of the retaining plate spaced therefrom form an acute angle of 30 ° or less, more preferably 5-10 °.

  The fixing surface of the retaining plate generally extends in a plane forming an acute angle of less than 30 °, preferably 5-15 ° with the plane in which the lower gripping section extends in the cross-section where the plane is indicated by lines.

  Preferably, the lower gripping section is formed only in a part of the surrounding area. Accordingly, the lower gripping section preferably extends in the area of the surface receiving the lower gripping section within 1/10 to 1/5 of the circumference of the holding plate.

  With respect to the central axis of the supply opening, two opposing lower gripping sections are preferably formed, correspondingly two engagement spaces being formed. The engagement space is engageable with a respective fitting projection of the vacuum cleaner.

  Preferably, the fitting projection is pivotable about a pivot axis, in which case the fitting projection is pivoted about the pivot axis at the inserted position. In the position not affected by the holding plate or the engagement space, the fitting projection is preferably moved to the basic position where it is biased by a spring and restrained. In this basic position, the projection is restrained against the filter chamber or a section of the vacuum cleaner. Only when the fitting projection has entered the associated engagement space of the mounted holding plate does the swinging movement of the fitting projection move into a position allowing the filter chamber to be closed.

  The mating projection penetrates into the engagement space in an entry direction perpendicular to the direction of extension of the lower gripping section. In the substantially U-shaped cross-sectional shape of the engagement space, it is preferable that the insertion projection enters the engagement space at right angles to the U-section.

  During the closing of the closure cover, while the cooperating projections cooperate with the retaining plate, they provide a predetermined positioning of the retaining plate seal with respect to the suction / blowing sleeve or the bottom of the filter chamber. Also preferably and preferably in the subsequent closing position of the closure cover, the fitting projection is crimped and held in this position in such a way that the sealing area of the holding plate, for example in the form of a ring collar with a sealing lip, makes a sealing fit. Apply force to the holding plate as described.

  Preferably, a closing prevention device is provided in the filter chamber. The closure blocking device cooperates with the associated inset projection when attempting to move the closure cover to the closed position when the dust filter bag is not or is not properly installed. In this case, the snap-in projections do not enter the engagement space when swung, but impinge on a closing-blocking device which prevents further swinging of the closing cover.

  The closure blocking device may be a rib or a protrusion. Preferably, a closing blocking pocket is provided in which the fitting projection penetrates the partial area.

  Preferably, two fitting projections are provided. Preferably, each of the two mounting projections is associated with a closure preventing device.

  The fitting projections are preferably held on the closing cover so that they can swing independently of one another. The swinging movement of one of the fitting projections is based on a unique movement, and does not necessarily follow the movement of the other fitting projection.

  Accordingly, the holding plate is preferably transferable and / or can be held in an airtight fit by means of one or more fitting projections.

FIG. 18 shows a corresponding view of FIG. 17 with respect to the closing prevention position of the closing cover in which the dust filter bag is not mounted.

  First, according to FIG. 1, a vacuum cleaner 1 of the type of a handle operated manual electric vacuum cleaner comprising a basic housing 2 containing a motor / fan unit, not shown, wherein the basic housing 2 The vacuum cleaner 1 is shown and described, to which an openable filter chamber 3 for a dust filter bag 4 is connected.

  A handle 5 is fixed to the basic housing 2 for operating the vacuum cleaner 1. The handle 5 has a hand grip 6 at the end, and the hand grip 6 is provided with a switch 7 for electrically starting and operating the vacuum cleaner 1. The supply of electricity takes place via an electric cable 8, which penetrates into the hand grip 6.

  In the embodiment shown, the floor is cleaned via the floor nozzle 9. The floor nozzle 9 is connected to the basic housing 2 and a motor fan unit arranged therein via a coupling 10 which is not shown in detail in flow technology and possibly also electrically.

  During operation of the vacuum cleaner 1, the dust collecting filter bag 4 is held in the filter chamber 3. The dust collecting filter bag 4 has a dust collecting bag 12 fixed to a holding plate 11. The dust bag 12 is preferably made of wool.

  The filter chamber 3 can be opened in order to remove the dust filter bag 4, in particular to allow the dust filter bag 4 to be replaced. For this purpose, a part of the filter chamber 3 is formed as a lid-shaped closing cover 13, which can be swung about a swing axis x with respect to the fixed part of the filter chamber 3.

    FIG. 2 shows the closing cover 13 in a closing blocking position for the closing movement of the cover.

  A suction through-opening 14 is formed in the filter chamber 3, and dust sucked in the operating state is collected in the dust filter bag 4 existing in the filter chamber 3 via the suction through-opening 14. Depending on the configuration of the vacuum cleaner 1, dust can be blown or sucked into the dust filter bag 4, respectively.

  During use of the vacuum cleaner 1, the filter chamber 3 is substantially perpendicular or perpendicular to its longitudinal direction, which corresponds to the direction of the bottom surface 16 visible here, to other surfaces not shown above it. It is preferable that they be arranged so as to extend at an acute angle to the line.

  A fitting projection 15 is arranged inside the closing cover 13. It is preferable that two fitting projections 15 are provided at intervals in the extending direction of the swing axis x.

  As can be seen from FIG. 2, each fitting projection 15 can be arranged inside the closure cover 13. In this case, it is more preferable that each fitting projection 15 be arranged on the closing cover 13 so as to make a swinging motion. In this case, the swing axis y of each fitting projection 15 is aligned with the swing axis x of the closing cover 13. Preferably, they extend parallel or at least approximately parallel.

  The fitting projections 15 are arranged so as to be swingable independently of each other around respective swing axes. The swing of one fitting projection 15 does not always follow the swing of the other fitting projection 15.

  This can be achieved by individually forming the fitting projections 15. The two mating projections 15 may be pre-formed so as to be easy to fit, for example by forming a connection between the mating projections, so that this connection allows the rocking projection 15 to swing independently of each other. Good.

  Each fitting projection 15 may be further spring-biased to the fitting position. For this purpose, it is further preferred that a spring, e.g. a leg spring, is assigned to each telescoping projection 15, which urges the telescoping projection 15 into a pivoting position, preferably limited by a stopper. In the operative position, even if an attempt is made to close the closure cover 13, the fitting projection 15 is locked without any other means into the closure blocking device formed in the bottom surface 16 of the filter chamber 3. .

  The closure blocking device may be a shoulder or a projection that allows cooperation with the associated inset projection 15. The closure-blocking device is preferably a closure-blocking pocket 17, which extends below and into the bottom surface 16 (see also FIG. 18).

  Each engagement projection 15 is associated with a closure blocking device, in particular a closure blocking pocket 17.

  The fitting position shown in FIG. 2 corresponds to that the fitting projection 15 cooperates with the closing blocking pocket 17 so that the closing cover 13 is prevented from closing when the dust filter bag 4 is not mounted. Acts to be locked. An abnormal closing of the filter chamber 3 can prevent the vacuum cleaner 1 from starting using electrical and / or mechanical means.

  In order to be able to move the closing cover 13 into the closed position of the filter chamber 3, the fitting projection 15 is turned against the spring force acting on it, so that entry into the closing blocking pocket 17 is prevented. First, the turning of the fitting projection 15 is premised.

  This turning operation of the fitting projection 15 is given by the area of the holding plate 11 when the dust filter bag 4 is mounted.

  In the drawing, essentially only the holding plate 11 of the dust filter bag 4 is shown. As can be seen from the drawing, the dust bag 12 connected to the holding plate 11 is only shown in outline by a dashed line, and is not completely shown.

  In the embodiment, it is preferable that the holding plate 11 is formed in a lattice shape within a range of the fixing surface E to the dust collecting bag 12. The holding plate 11 may be formed as a plastic injection molded product.

  The holding plate 11 has a supply opening 18, which is surrounded by a collar 19 projecting into the dust bag 12. The supply opening 18 is closed by a lid-like closing part 20, in particular when the vacuum cleaner 1 is switched off, ie when no suction air flow is formed. The closure part 20 is pivotable from a closed position of the supply opening to an open position, preferably about an axis extending parallel to or at least approximately parallel to the pivot axis x of the closure cover 13, in this open position: The closure part 20 has been moved in the direction of the interior of the bag (see FIG. 7 for this purpose).

  The movement of the closing part 20 to the open position is preferably performed only by the suction air flow acting on the closing part 20 during operation of the vacuum cleaner 1. Opening aids which act mechanically on the closure part 20 and which assist the opening process may be provided.

  As indicated by the dashed-dotted line 21 showing the outer connection contour of the dust bag 12 with the holding plate 11, the holding plate 11 moves in the lateral direction, here within the extension width of the filter chamber 3, Project beyond.

  The holding plate 11 is preferably formed in a lattice shape in a portion 23 of the holding plate 11 protruding beyond the dust bag 12, and preferably also in other portions. Can be achieved during the continuous operation of the vacuum cleaner, in which case this part 23 of the holding plate 11, which forms the fixing surface E on the upper side, has a grid-like structure. Depending on the mode of operation, respectively, it allows a through-flow of air sucked from or blown from the dust bag 12.

  Attached to each part 23 of the holding plate 11 configured in a lattice shape, a lower gripping section 24 is formed in the holding plate 11. Preferably, two lower gripping sections are formed on the basic body of the holding plate 11 that provides the fixing surface 22 for the dust bag 12 at the same time as the grid-shaped part 23.

  In the projection in the direction of supply of the dust-containing air flowing into the dust bag 12 (see arrow a in FIG. 7), the lower gripping section transitions to the fixing surface 22 and the respective attached part of the holding plate 11 23 at least partially overlaps, in which case there is a spacing between the lower gripping section 24 and the part 23 of the associated holding plate, as viewed in the feed direction a.

  Each lower gripping section 24 extends around the holding plate 11, in particular within approximately one fifth of the circumference of the base body of the holding plate 11. Furthermore, each lower gripping section 24 has a length from the edge of the retaining plate that extends essentially parallel to the hinge axis of the closure portion 20 and a length of the narrow side seen perpendicular to the longitudinal extension direction of the retaining plate 11. (See dimension L in FIG. 10).

  In the section of the area of the holding plate 11 that supports the lower gripping section 24, the lower gripping section 24, the grid-shaped portion 23 and the attached basic body section of the holding plate 11 define a U-shaped engagement space 25. Form. The U-shaped engagement space 25 is open on both sides in the longitudinal extension direction of the lower gripping section 24, that is, in the extension direction of the shorter holding plate dimension L, and also on the side of the holding plate away from the basic body. That is, it is also open radially outward with respect to the central axis z passing through the supply opening 18.

  The mutually facing faces of the lower gripping section 24 (face F) and of the retaining plate portion 23 (face E) form an acute angle α of about 5-10 ° in the longitudinal direction of the lower gripping section 24; In this case, the spacing decreases uniformly in the direction of the section of the retaining plate part 23 that extends beyond the lower gripping section 24.

  Correspondingly, the abutment surface of the lower gripping section 24, which is oriented in the direction of the holding plate part 23, also extends at this angle with respect to the fixing surface 22 for the dust bag 12.

  The engaging openings 25 arranged opposite to each other allow the user to insert, for example, two fingers into the engaging space 25 to support the holding plate 11 so that the dust collecting filter bag 4, particularly the filled dust collecting filter bag 4 Advantageously, it is advantageously available to remove and even carry in particular. In this case, the filter-shaped holding plate portion 23 does not come into contact with the wall of the dust bag that is spaced from the engagement space 25.

Further, the lower grip section 24 is positioned so that the lower grip section 24 covers the chamber-side closing prevention pocket 17 when the dust filter bag 4 is mounted in the filter chamber 3 (FIG. 5). reference).

  The holding plate 11 of the dust collecting filter bag 4 has a sealing collar 26 on the lower side, that is, on the side opposite to the collar 19, which surrounds the holding plate 11. It is mounted in the filter chamber 3 so as to surround the connection collar 27 of the blowing sleeve 32. The suction / blowing sleeves 32 are all formed on the end side of the suction channel 28 led into the basic housing 2.

  The sealing collar 26 of the holding plate 11 is further provided with a sealing lip 29 which extends circumferentially from the circumferential edge of the sealing collar 26 so as to cooperate with the connecting collar 27. It is preferable to protrude in the direction.

  After the user attaches the dust collection filter bag 4, it is preferable that the holding plate 11 is initially located at the temporary attachment position (see FIG. 4).

  When the closing cover 13 is moved in the direction of the closed position of the filter chamber 3, the fitting projections 15 enter into the retaining space 25 on the holding plate side, each of the fitting projections 15 being a lower gripping section facing the portion 23 of the holding plate. 24 are supported on the contact surface. Thereby, the fitting projection 15 is turned against the spring force acting on the fitting projection 15.

  When the cover 13 is further pivoted into the closed position, the fitting projection 15 slides on this abutment surface of the lower gripping section 24 and further into the respective engagement space 25.

  The pivoting movement of the fitting projection 15 performed against the spring force is preferably limited by a stopper (abutment projection 35), whereby the closing cover 13 is completely moved to the closed position as shown in FIG. When moved, a force component acts on the lower gripping section 24 via the fitting projection 15 to move the holding plate 11 (further) to the hermetically fitted position shown in FIG. The horizontal basic shape of the sealing lip 29 changes in cooperation with the outer surface of the connecting collar 27, and the sealing lip 29 abuts against the outer surface of the connecting collar 27 in a curved and airtight manner.

  The holding plate is simultaneously supported on the bottom surface 16.

  The airtightness between the connection collar 27 and the bottom surface 16 of the filter chamber can be achieved, for example, by injection molding as a 2K soft component or surrounding the connection collar 27 as a separately mounted seal, the connection acting from below on the bottom of the filter chamber. This is achieved by a section of collar 27.

  In order to mount the holding plate 11 in the correct position, a web-shaped positioning protrusion 30 is provided on the bottom surface 16, and the positioning protrusion 30 is formed by a positioning slit 31 formed in the holding plate portion 23 formed in a lattice shape. Engage with.

  The holding plate 11 may be formed with a projection that cooperates with a recess and / or a notch in the receiving chamber.

  FIG. 15 shows a face in which the part 23 of the holding plate is closed with a rear gripping region 33 of the holding plate having a width greater than the distance between the edges of the positioning projections 30 facing each other (this surface saves material, for example). FIG. 1 shows an embodiment of the holding plate 11 formed as a hole. The wider area of the holding plate portion 23 is provided with a width corresponding to this interval or a width exceeding this interval.

  This allows (intuitively) correct placement of the holding plate 11 in the filter chamber 3. The holding plate 11 erroneously mounted 180 ° in the opposite direction is not positionable because the holding plate 11 slides forward due to the inclined bottom surface 16. The holding plate 11 is supported by the positioning protrusion 30 at the correct mounting position by the rear grip region 33.

  A closing prevention rib projecting upward from the bottom surface may be provided instead of the closing prevention pocket 17 on the bottom side, and when the dust filter bag 4 is not mounted, the fitting projection 15 abuts against the closing prevention rib. Locked. When the dust filter bag 4 is installed, the closing prevention rib is received by a pocket formed on the lower side of the lower grip section 24 or the like.

  The dust bag 12 may be creased, for example, on the manufacturing side or may be compactly folded as a roll (see FIG. 16). The compact shape is held by one or more, in particular two band-shaped material bands 34 surrounding at least part of the dust bag 12 and the holding plate 11. Material band 34 may be a paper band.

  The material band 34 clamps the engagement space 25 from above.

  During the closing process of the closing cover 13, first, the tip of the fitting projection 15 hits the surface of the material band 34. When the fitting projection 15 further enters the engagement space 25, the material band 34 extends completely and finally breaks as scheduled.

  Due to the closing movement of the cover, the fixing action of the one or more material bands 34 is released, so that during operation of the vacuum cleaner 1, the dust bag 12 is assisted by the vacuum action on the dust bag wall. To take the final size and shape of the folded crease / roll.
