Definitions

  • the invention relates to an electric vacuum cleaner according to the preamble of claim 1.
  • An electric vacuum cleaner of this type is known from DE-A-3 217 240.
  • the chamber for receiving a filter bag is located spatially above the motor fan.
  • the blower air is directed into the end of the filter bag facing away from the motor fan via a line running along the filter bag.
  • the corresponding line also forms a foldable intermediate carrier for the filter bag detachably suspended from it.
  • the filter bag and the tubular intermediate carrier arranged to the side assume an approximately vertical position. Beyond this vertical position, the housing enclosing both parts opens out in a V-shape, so that the filter bag can be removed upwards.
  • the fan air duct connects to the intermediate carrier via a corresponding hinged joint position. Setup and handling are relatively complex.
  • the object of the invention is to improve a generic electric vacuum cleaner in a technically simple manner, especially in that a clean, convenient removal of the filled filter bag is given and the plunging assignment of the filter bag can be used for a supply close to the motor housing.
  • filter bag handling on generic devices is made considerably easier. Leakage of dust or the falling out of larger, heavier particles is practically prevented, simply by the advantageous change of position of the filter bag from its falling position, with the opening facing downward, into the upward position when it is removed.
  • the filter bag can even be changed in the normal position of use of the electric vacuum cleaner; it does not need to be transferred to a special position, for example in the case of a standing device.
  • vacuum cleaner types of this type the proven, technologically favorable arrangement can be maintained, namely that the motor works from the bottom up and the filter bag is filled from below with the dusty air without detours.
  • connection connection of the filter bag faces the motor housing
  • filter bag intermediate carrier which has a valve closure body
  • nozzle connection connection separates automatically while pivoting the chamber further into the open position (chamber nozzle is then open towards the top).
  • connection connection to the blower air duct and connection piece connection are spatially combined.
  • the entrained filter bag intermediate carrier acts like a moving cover of the nozzle connection. As soon as the intermediate carrier has reached the position mentioned, the filter bag can be detached. Since the opening of the filter bag is only exposed in this position, the filling content is surely retained against falling out. It is a further advantage that the valve closure body sits on the intermediate carrier. The valve bags therefore no longer need to be equipped in this regard.
  • Of particular advantage is the completely automatic separation of the connector connection by stopping the pivoting movement of the intermediate carrier while pivoting the chamber connector further. If this swiveling movement of the chamber nozzle includes a fully usable angle of 180 °, the filter bag can simply be pulled out of the then vertically open, upwardly open chamber like an insert.
  • connection piece connection to a bottom of the filter bag, the surface shape of which corresponds approximately to the cross section of the chamber connection piece.
  • the latter practically forms a connection collar for the porous, in particular textile, wall of the chamber receiving the filter bag attached to it.
  • the textile wall can be stiffened by a metal basket, a plastic frame or the like. If such is missing, the corresponding bag body can be detachably attached to the handle of the electric hand-held vacuum cleaner in a hanging arrangement.
  • the corresponding cross-section is also fully used.
  • a stable, defined assignment of the filter bag also results from the fact that its bottom rests on an edge step on the inner wall of the chamber connector.
  • the wall of the filter bag springs back slightly by the corresponding overlay.
  • the folding axis of the chamber nozzle is arranged approximately at the level of the support of the filter bag base.
  • the intermediate support and the chamber connection piece pivot appropriately about a common folding axis.
  • the stopping of the intermediate carrier in the said, approximately vertical, filter bag release position is expediently effected by a pivot limiting stop which is located adjacent to the common folding axis. Unfolding is facilitated by a handle on the free end of the intermediate carrier.
  • the closed position is secured in the usual way, for example by means of a push-button lock latch.
  • the invention proposes that the valve closure body is realized by a valve flap on the upper end edge of a connecting piece of the intermediate carrier which plunges into the bottom of the filter bag. It can be a rubber flap or a plastic flap with the corresponding properties. Given a corresponding toughness of the intermediate carrier material, a molding of the same material is also conceivable.
  • the procedure is continued so that the front edge of the nozzle slopes towards the folding axis.
  • the connecting piece is also advantageously curved in the folding radius of the intermediate filter bag.
  • the easy removal of the filter bag from the chamber can nevertheless be facilitated by the fact that the bottom of the filter bag forms gripping niches.
  • cams of the intermediate carrier which act to support the wall, plunge into the gripping openings.
  • Corresponding cams are at the same time an indicator of whether the filter bag is inserted in a functional manner and whether it is the operationally appropriate filter bag.
  • orientation features on the circumference of the filter bag base are also useful, which counter-features are arranged in the region of the inner wall of the chamber connector.
  • the bottom of the filter bag rests only on the opposite edges which run transversely to the gripping niches. As a result, the base is even given a certain amount of deflection, so that if any particles intervene, the base of the filter bag is not damaged, but can escape.
  • the folding axis of the intermediate carrier is eccentric to the folding axis of the chamber nozzle that there is a locking engagement between the two folding parts at the beginning of the pivoting movement approximately in the vertical position of the intermediate carrier picks up.
  • the corresponding coupling means are designed in such a simple way that the latching projection for the latching engagement sits at the free end of the chamber connector and the associated latching shoulder on the corresponding front end of the intermediate carrier.
  • An advantageous latch function can finally be achieved with simple means in that the latching projection is designed as a latch nose and sits on a flexible wall part of the chamber connector.
  • connection point connecting piece
  • length of the harmonica hose results in a certain suction effect.
  • This effect also contributes to the fact that said particles are not pushed outwards, but be sucked in.
  • further variant which in concrete terms consists in the pipe connection being formed by a hose which is pushed onto a guide pipe. In this way, a type of telescopic tube connection is created, the guide tube being rigid and the hose forming the line being flexible, so that it can optimally take part in the required curvature due to the folding movement of the filter bag intermediate carrier.
  • the last variant consists in that the pipe connection is designed by a pipe which can be bent and is correspondingly bendable and which extends through the filter bag intermediate carrier and extends into the filter bag.
  • a pipe which can be bent and is correspondingly bendable and which extends through the filter bag intermediate carrier and extends into the filter bag.
  • such a configuration has the advantage of utilizing the filter space for the line.
  • the pipe reaching into the filter space in the use position like a standpipe is closed very late due to the collected dust etc.
  • this has the advantage that the dust is introduced above the deposit of the dust. This is more energy-efficient or brings a virtually constant suction power. There is no need to "work" against the resistance of the suction material.
  • the tube can be designed as a flexible extension of the motor housing.
  • the electric vacuum cleaner shown is designed as a handheld device. It has a housing 1, to which a handle 2 is connected at the top with an end handle 3. In the transition area between handle 3 and handle 2 there is an on / off switch 4. The electrical cable connection is not shown.
  • the housing 1 is subdivided into a motor housing 5 and a chamber 6 extending thereon for receiving a filter bag 7.
  • the motor fan is also not shown in detail in the drawing.
  • the side of the filter bag 7 facing the motor housing 5 is in the connection connection V to the blower air duct 8.
  • the underside of the motor housing 5 merges into a pipe coupling 9, which establishes the air flow connection to a suction nozzle 10.
  • the suction nozzle 10 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 thus works from the bottom up, consequently pushes the dust air into the filter bag 7, which is arranged to fall above the motor housing 5.
  • the cross section of the housing 1 is generally rectangular with slightly bulging broad sides and narrow sides. In Figure 1, the vacuum cleaner can be seen from the broad side.
  • the chamber 6 receiving the cross section corresponding to the filter bag 7 is formed by a wire basket stiffened textile bag 11 which at the bottom, i.e. merges into a stiffened edge in the form of a chamber connector 12 on the motor housing side.
  • the stiffened textile bag 11 can be assigned to this chamber connector 12 by means of the detachable clip plug connection.
  • the plug-on area is separated.
  • the stage can be seen in Fig. 1. It is designated by 13 and allows a defined interior or exterior assignment of the textile sack. An internal plug assignment is preferred.
  • FIGS. 1 here in dash-dotted lines
  • the folding axis 14 which enables this is located on one narrow side of the housing 1.
  • Their bearing eyes on the chamber neck are designated by 15. These bearing eyes are on Transition area between the narrow side and broad side of the chamber 6.
  • a continuous bearing eye of the motor housing 5 extends between the two bearing eyes 15.
  • an intermediate carrier T is also integrated, on which the filter bag 7 is seated.
  • the filter bag intermediate carrier T has a floor plan adapted to the housing cross section, but comes back from the casing wall of the housing, so that it is essentially completely hidden from view in the coaxial position of the motor housing 5 and chamber 6 shown in FIG. 1. Except for a small access point, it is grasped by the flared lower edge of the chamber connector 12 of the filter bag intermediate carrier T, which is also foldable, and folds about the same folding axis 14 as the filter bag chamber 6.
  • the intermediate carrier T therefore also forms the hinge side, as is the case also the chamber connector 12, two bearing eyes, which are designated 16 here.
  • the filter bag 7 directly adjoining the intermediate carrier T has a bottom 17. Its general outline also corresponds to the cross-sectional shape of the chamber connector 12, which forms an edge step 18 on the inner wall for support purposes in the region of the narrow sides of the bottom 17. As a result, the bottom 17 cannot slide into the chamber 6 in the opened position of the device.
  • the common folding axis 14 of the chamber connector 12 and the filter bag intermediate carrier T extends approximately at the level of the support edge step 18 of the filter bag base 17. In a closed housing (FIG. 3), the edge step 18 extends over the top of said base 17, so that it blows during suction is not lifted upwards.
  • the bottom of the bottom 17 rests, as already indicated, on the top of the intermediate filter bag T. This results in Areas of the narrow side of the bottom 17 a kind of clamping jaw border between chamber connector 12 and intermediate support T.
  • blower air duct 8 projects with its stepped, cylindrical mouth end 8 'into the lower region of a nozzle 19.
  • the latter protrudes over the top of the filter bag intermediate carrier T.
  • the connecting piece 19 is molded onto the intermediate carrier T and, projecting through an opening 20 of the filter bag base 17 corresponding to a cross-section, extends into the interior of the filter bag 7.
  • the connector 19 forms a valve flap 21 at its free end.
  • the latter lies freely with the predominant edge area on the front edge of the connector 19. It is only fixed at the point designated 22, so that it lifts off under the action of the air flow, but returns to its closed position when the corresponding underside load decreases.
  • the valve flap 21 can be created as a separate component and assigned to the location 22 by means of the clip assignment; alternatively, of course, there is the possibility of molding with a correspondingly flexible material of the connector 19 or filter bag intermediate carrier T.
  • the nozzle 19 tapers towards its free end, so that its insertion into the opening 20 has a practically centering effect.
  • the end edge 19 ' is chamfered. It slopes in the direction of the folding axis 14. A line in this direction intersects the folding axis.
  • the connection point 22 is located in the higher area of the nozzle edge.
  • the socket 19 takes a radial curvature to the axis 14. Between the root region of the socket 19 and the area on the folding axis side, the intermediate carrier T is broken like a window. The corresponding opening has the reference symbol 23.
  • the frame leg on the hinge side has a greater width than the two frame legs facing the broad side wall of the housing.
  • the intermediate carrier T forms a freely accessible handle 24 on its end face there. It is an underside angular extension. This arises from an area that springs back relative to the end face 25 there.
  • the relevant leg runs vertically.
  • the adjoining, essentially horizontal leg runs back to the casing wall of the housing and closes with it at the same level.
  • a hook-type latching device which secures the closed position of the housing and can be actuated by a pushbutton, and is not shown.
  • the corresponding zone of the motor housing 5 is recessed like a niche. The recess bears the reference number 26.
  • cams 27 point upwards in the region of the longer frame legs of the intermediate carrier.
  • the latter close gripping openings 28 on the longer marginal edges of the filter bag base 17.
  • Both gripping openings 28 are rounded and open to the corresponding inner wall of the chamber connector. In the open position of the housing 1, the filter bag can be comfortably grasped by the clamping handle of the central zone of the base 17 drawn in like a wasp waist and lifted out of the chamber 6.
  • the filter bag intermediate carrier T is assigned and designed to have a limited pivoting angle passes through, ie cannot reach the 180 ° angular position of the chamber connector 12; Rather, it remains in the position which lies approximately in or beyond the vertical position EE of the nozzle connection cross-sectional plane, so that the nozzle connection connection V is already beyond the bisector of the maximum swivel range of 180 °. In this position there is enough space for the filter bag 7 to pull it off the intermediate carrier (cf. FIG. 5).
  • the corresponding position is defined by a limit stop 29 between the bearing eye of the motor housing 5 and the back flank 30 in the folding direction of one or both bearing eyes 16 of the filter bag intermediate carrier T (cf. FIG. 6).
  • the bottom 17 has orientation features 32 in the area of both narrow sides, which engage in matching counter features 33 in the area of the inner wall of the chamber connector 12.
  • the orientation features are trapezoidal projections on the narrow side of the plate-like body forming the bottom 17. In this way, an alignment-appropriate position between opening 20 and connecting piece 19 is achieved before a misassignment is noticeable only when the housing parts do not come together properly.
  • the facing longitudinal sides 27 'of the cams 27 are, as shown in Fig. 4, rounded transversely, which also serves the correct assignment of the bottom 17. They act like control surfaces on the corresponding rounded niche base of the gripping openings 28.
  • a separation of the intermediate carrier T from the chamber 6 of the Filter bag 7 can alternatively also be made so that the folding axis of the intermediate carrier T is eccentric to the folding axis of the chamber connector 12, that a present at the beginning of the pivoting engagement between the two folding parts is canceled approximately in the vertical position of the intermediate carrier T.
  • the corresponding eccentricity is around 1.5 mm.
  • the axis offset would be directed upwards, that is to say would run in the plane EE.
  • the corresponding configuration is implemented in such a way that the locking projection 39 for the locking engagement sits at the free end of the chamber connector 12. It is a nose formed on the inner wall of the chamber connector 12. This points in the direction of the axis 14.
  • the associated locking shoulder is designated 40. It lies on the corresponding front end of the intermediate carrier T. Taking the eccentric axle bearing into account, the intermediate carrier T, which acts as a drag cover, extends approximately in the vertical position from the area of the latching projection 39. On the other hand, the filter bag chamber can also be closed when the intermediate carrier T is brought into the position shown in FIG. 3. A type of latch function occurs here, since the locking projection 39 is practically designed as a latch nose and sits on a flexible wall part of the chamber connector 12. This wall section therefore springs out.
  • a blower air pipe connection R pointing in the direction of entraining starts from the underside of the filter bag intermediate carrier T facing the motor housing 5.
  • this pipe connection R is formed by a harmonica hose 41.
  • the latter bridges the area between the said connector 19 and the blower air duct 8 of the motor housing 5 in terms of flow.
  • the relevant end is in the blower air duct 8 fastened on the inside.
  • the other end on the filter bag side is also firmly seated in the connector 19.
  • a plug-in adhesive connection can be used.
  • the insertion depths are defined by a ring step 42 or the like, of which only that is shown in the area of the nozzle 19.
  • the harmonica hose 41 is made of rubber or plastic with corresponding properties.
  • the plug ends are cylindrical.
  • the filter bag 7 is separated from the nozzle 19.
  • the suction material remaining behind the valve flap 21 falls back through the pipeline R or remains in the pipeline area. If a corresponding valve flap 21 is not provided, folding up the intermediate carrier T into the vertical E-E already causes the mouth of the connecting piece 19 to be sucked free in the direction of the motor housing.
  • the pipe connection R is formed by a hose 44 which is pushed onto a guide pipe 43 of the motor housing 5.
  • the latter has the flexibility necessary with regard to the pivoting movement of the intermediate carrier T.
  • a free push-on connection is sufficient, on the other hand, an attachment of said hose 44 is required on the intermediate carrier side. This can be done by a simple covenant or the like.
  • commercially available material can be used, such as steel spiral reinforced hoses.
  • the stationary guide tube 43 is molded or assigned to the motor housing 5 in a free-standing manner like a type of connecting piece. In the present case, a kind of telescopic pipe connection results due to the pipe division and guidance.
  • the hose 44 could also be slidably mounted inside the guide tube 43.
  • the embodiment according to the third embodiment of this type consists in that the pipe connection R (see FIGS. 15 and 16) is designed by a flexible pipe 45 pointing in the direction of entraining.
  • the latter passes through a suitable opening in the intermediate carrier T and projects freely into the interior of the filter bag 7 in the use position of the vacuum cleaner, expediently up to just before the ceiling.
  • As a standpipe it introduces the dust-laden air overhead, i.e. the dusty air does not pass through the already deposited suction material.
  • the tube 45 is also designed to be flexible and forms a collar 46 at the end as a safeguard against withdrawal from the intermediate carrier T. If the tube 45 is excessively long, however, this measure can be omitted, since the end position of the filter bag intermediate carrier T is defined, as explained.
  • the assignment of the tube 45 takes place, for example, by means of the screw or plug connection.
  • the harmonica hose 41 which folds up in the smallest space, is accommodated in a contracted position (FIG. 13) in a receiving chamber 47 of the motor housing, to the bottom of which the fan-air duct 8 connects.
  • This receiving chamber 47 located below the filter bag intermediate carrier T can easily be taken into account in terms of shape.
