Description

The invention first relates to a method for vacuuming with a Handheld vacuum cleaner, the dust first in a dust collector, For example, a dust filter bag is included and subsequently is disposed of, and an odor adsorption is also carried out by means of an adsorbent, for example activated carbon.

Such methods are known, for odor adsorption Adsorption filters are used, the main components of which are adsorbent to bind the odorants and a suitable carrier material for fixation of the adsorbent. Highly porous materials are used as adsorbents used, in many cases z. B. activated carbon used. But find it other materials such as B. zeolites or porous organic polymers Use. The adsorbent mostly consists of particles that in different shapes and size fractions can exist. This are made with the help of various support structures, such as foam, fabric, fleece, Honeycombs etc. distributed in a defined manner over the filter. Such one Odor filter is arranged in the device so that it is in operation the pumped air flows through the device. Usually is a such filter arranged on the suction side in front of the blower, so that Adsorption equilibrium in the filter is not affected by the increased temperature the engine blower unit is negatively affected. It is also known for the purpose of covering an unpleasant smell porous, with Media impregnated with fragrances in room air cleaners and vacuum cleaners use. Here sticks and granules are known, which are in a filter bag be introduced or also in the flow path of the air. The separation of odorous substances in a vacuum cleaner is specific Conditions. Unlike z. B. in a room air purifier in one Vacuum cleaner the dust picked up in a dust filter bag or other special dust collection container retained and collected. The Dust picked up remains in this filter bag for a certain period of time or container. During this time, the microbiological degradation various dust constituents a large part of the undesirable odorous substances produced. In the case of a vacuum cleaner, the main disadvantage is known solutions now that the separation of the odorous substances in the Essentially takes place during the operation of the vacuum cleaner Odor substances through convective transport with the flowing air in the Odor filter. On the one hand, this causes it An undesirably high pressure drop flows through the filter. On the other hand demands the high that suddenly starts after switching on the vacuum cleaner Concentration of odorous substances in the suction air is a very good one Adsorption kinetics of the filters

From US-A 5 461 751 it is known to use cedar pieces as air fresheners and to put pesticides in a dust filter bag. The Releases of the cedar wood cover and fragrance at the same time pesticidally. In a comparable way it is from FR-A 2 417 287 Known bactericides, fungicides or odorous substances in one Insert dust filter bag. WO 94/21305 A deals with one free-flowing means for air improvement as such and suggests one Combination of a sand and fragrance before. The previously known Objects therefore each contain their own odor-releasing substances. These are also effective when a vacuum cleaner is at a standstill. At the Switching on a vacuum cleaner are increasingly in the dust filter bag accumulated odorous substances are released and lead to a not always considered advantageous odor pollution.

In view of the prior art described above becomes a technical problem of the invention first seen in it a method of vacuuming training with a handheld vacuum cleaner in an advantageous manner such that taking into account a small Pressure loss, especially after switching on the smell surge suddenly starts in the vacuum cleaner is prevented.

This problem is with regard to the procedure by the subject of the claim 1 solved. As a result of this configuration specified a process in which the odorous substances be bound at the place of their origin. this happens in that the adsorbent in the immediate vicinity of the dust is introduced. The amount of Adsorbent can be comparatively small, for example between 3 and 30g, preferably between 5 and 50g depending on the usual Dust collection room. The adsorbent is in particular of loosely introduced or inserted adsorbent granules. The scents are not only due to the Flow during the operation of the vacuum cleaner Transported adsorbent. Rather, the transport takes place especially in times when the device is at a standstill, by diffusion of the odorants instead. In advantageously omitted by the proposed Invention of the pressure loss of a filter, which during of the operation of the device flows through the air becomes. Furthermore, enriching a larger one Amount of odorous substances in the dust filter bag or in prevents the dust collector from forming Diffuse odors continuously to the adsorbent and be bound there. As a consequence, that, in contrast to the known odor filters, none relatively large amount of odorants in a short time must be adsorbed. A diffusion odor filter according to the invention therefore comes with a mediocre Adsorption kinetics without the breakthrough of a intense swell of smell when switching on the device he follows. By the method according to the invention when vacuuming the odor molecules eliminated, which carried out immediately after switching on the device become. The adsorbent can be used in various processes entered directly into the dust collection room or be entered. For example, it is conceivable that before the start of a first suction process or at Beginning of each suction process the adsorbent in the dust collection space, if necessary in the suction filter bag is introduced. In this regard, it can be provided that the adsorbent such as activated carbon, which in broken / spherical form or as fibers, in portions filled in a bag, which bag by the user before first use the dust filter bag or the dust collection space in this can be introduced. Such an adsorbent bag consists of a particularly air-permeable Material such as a thin fleece Paper or melt blown. In order to use this procedure sufficient spatial distribution of the adsorbent in the To reach dust collection space or in the suction filter bag it is suggested that several smaller bags be introduced with adsorbent, for example two bags of 5 grams of activated carbon each. In an alternative The method is designed in such a way that the adsorbent in bulk in the dust collection space or Dust filter bag is present. This proves to be so as advantageous that the adsorbent in intimate Is in contact with the suctioned dust, so that the Diffuse odors particularly easily to the adsorbent can. For example, the user can use a predetermined amount of adsorbent through the filling opening of the dust filter bag or in bring in the dust collector. Alternatively, it can Adsorbent in the form of activated carbon also in portions There are bags. The user can therefore before the start a first suction, i.e. after insertion a new dust filter bag or after emptying a predefined portion of adsorbent in the dust collection area Fill. It is also alternatively provided that the adsorbent is applied to the floor to be sucked is and together with the vacuumed up in the Dust collection space or placed in the dust filter bag becomes. So the adsorbent is in the form of particles as bulk goods in an empty dust filter bag or dust collection area. It is also conceivable here that adsorbent by means of a dosing container predefined output of an adsorbent portion on the to spread soil to be sucked. Another alternative is provided that the adsorbent in a storage container in the dust collection room or in the dust filter bag is present and in the course of vacuuming from the storage container is sucked out. For example, in Area of the suction air inlet opening of the dust filter bag or the dust collection area is an open edge Bag or a cup-like container can be arranged, from which when the vacuum cleaner is started up for the first time after changing the dust filter bag or after an emptying of the dust collection area or in the course a closing of the dust collecting space or the Dust filter bag receiving filter chamber the adsorbent into the dust filter bag or the dust collection area is introduced. It is conceivable that by at least partial destruction of the storage bag or of the container the adsorbent for distribution in the Room emerges independently. Furthermore, there are solutions conceivable, in which a container with a by the Suction air flow or through the in the dust collection room or the vacuum filter bag in an open position releasing the adsorbent Cover is provided.

The invention also relates to a dust filter bag for a vacuum cleaner according to the features of claim 6. As a result of this configuration the adsorbent is in intimate contact with the sucked in dust, so that the odorants especially can easily diffuse to the adsorbent. As a result the odorants are at the place of their origin bound. Here it proves to be particularly advantageous that such a diffusion odor filter inside of the dust filter bag with a mediocre one Adsorption kinetics manages without the breakthrough an intense swell of smell when switching on the Vacuum cleaner is done. As an adsorbent material here for example activated carbon, zeolites or porous Polymers are used, these in broken / spherical form or as fibers. The size distribution, the chemical Equipment (bactericidal and fungicidal substances) and The amount of adsorbent is related to the volume of the Dust filter bag and to the area of application, i.e. on adapted the substances likely to be absorbed. On the one hand, this depends on one if possible efficient adsorption of unwanted odors for which the ratio of macro, meso and Micropores in the adsorbent is decisive. On the other hand application-technical criteria are also decisive. For example, the adsorbent has the invention Dust filter bag the property itself evenly distribute in the bag and become as permanent as possible to be placed on the inside of the bag wall. In this regard, can be further provided that these requirements filled with a very fine-grained coal are. However, other materials can also be considered such as molecular sieves in the form of a Powder. The addition of a moisture-binding can also be advantageous By means of (e.g. Selicagel) be around Living conditions of microorganisms in the dust bag too deteriorate and at the same time the adsorption performance to increase the activated carbon. In the simplest case it is conceivable that adsorbent in the form of particles as bulk material before the start of a first suction process, i.e. after renewing the suction filter bag, on the one to be sucked Scatter the floor and into the empty dust filter bag suck. The adsorbent is located after this in intimate contact with the sucked in dust, so that the odorants are particularly easy to adsorb can diffuse. Alternatively, it can be provided that the adsorbent in an outside of the dust filter bag fortified storage container is arranged for emptied into the dust filter bag by hand. So will when inserting a new dust filter bag into the Vacuum cleaner, for example, one with a portion of adsorbent material filled bag, which further, for example removable on the holding plate of the dust filter bag is fixed, removed and torn open about this contained adsorption material through the suction opening sprinkle in the dust filter bag. Such Portioning bags can also be used in bulk in the dust filter bag be assigned, whereby the Possibility exists, the adsorption material contained therein sprinkle directly into the dust filter bag or spread on the floor to be vacuumed. Further alternatively it is proposed that the adsorbent in its own air-permeable wrapping inside of the dust filter bag is included. The wrapping consists of an air-permeable material such as a thin fleece made of paper or Melt-blown. Such an adsorbent bag can already be factory-installed in the dust filter bag. However, there is also the possibility of such Adsorbent bag loose or removable on the holding plate assign to the dust filter bag. The user brings this bag before using the dust filter bag for the first time through the inlet opening into this one, the size of the coating of the adsorbent to the Cross section of the inlet opening of the dust filter bag is adjusted. In this case, it preferably has a surface extension the envelope a fraction of a diameter dimension the inlet opening of the dust filter bag on. To further a sufficient spatial distribution of the To ensure adsorbent in the dust filter bag it is proposed that a plurality of adsorbent bags are contained in the dust filter bag or in these can be introduced. It is also envisaged that each have a plurality of adsorbent particles in an envelope are included. So it is suggested that in a dust filter bag two bags with 5 Grams of activated carbon are introduced. In another alternative embodiment of the subject matter of the invention it is provided that a by air flow or negative pressure Openable adsorbent storage container on one Inner wall of the dust filter bag is attached. So can one, first over the filler opening of the Dust filter bag extending storage container be provided, which when switching on for the first time the vacuum cleaner after changing the dust filter bag through the air flow or in the dust filter bag prevailing negative pressure from the inlet opening in the inside of the dust filter bag is torn. in this connection can be, for example, one with the adsorbent filled bag, which is initially in the Area of the inlet opening is kept close to the edge. By the air flow / negative pressure supply is this off torn the inlet area, after which the content through provided openings of the container in the bag interior can escape. Alternatively, such Container can also be perforated, with the Switch on the vacuum cleaner this along the perforation tears off and releases the contained adsorbent. Alternatively, such a container can also be cup-shaped, the inlet cross-section of the dust filter bag initially be designed to be occlusive. It is also also conceivable, a container on the underside of the holding plate to be placed near the edge of the filling opening. For example on the underside of the holding plate an annular, the container surrounding the filler opening is provided be determined by the air flow or the pending Vacuum when switching on the vacuum cleaner Release of the adsorbent torn off the holding plate or with which by inserting the air flow or the negative pressure of the adsorbent in the container restrained lid or the like in a that Adsorbent releasing position is shifted. About that there is also the possibility that the adsorbent in a storage container that can be opened by puncturing, for example in a bag, overlapping the Suction port opening of the dust filter bag arranged is. According to the invention, before initial start-up of the dust filter bag the user of this storage container pierce, for the distribution of the containing Adsorbenses in the dust filter. This is preferred Design there application in which an air flow suction nozzle connected to a suction channel when closing the one holding the dust filter bag Filter chamber through the suction port opening of the dust filter bag holding plate occurs. Accordingly, in the course this filter chamber closing process is covered to the suction port opening arranged adsorbent storage container pierced by the suction port and thus opened to release and distribute the adsorbent in the dust filter bag. Has proven particularly advantageous with activated carbon powder when choosing the adsorbent a grain size fraction between 0.15 and 0.25 mm, the undersize fraction is small with less than 2% is held. Activated carbon fibers are also very advantageous with a diameter of 0.01 to 0.1 mm and a fiber length of 10 to 100 mm. Particularly effective are also activated carbon powder made from coconut shells with CTC values greater than 60%.

The invention also relates to a dust collector for a vacuum cleaner according to the features of claims 15 and 16. Such vacuum cleaners are known where the vacuum is in the filterless one System is deposited in the collection room. The filled one Collecting space is for emptying the device housing removable. As a result of the configuration according to the invention the adsorbent is in intimate contact with the sucked in dust, so that the odorants especially can easily diffuse to the adsorbent. As a result the odorants are at the place of their origin bound. Here it proves to be particularly advantageous that such a diffusion odor filter inside of the dust collection room with a mediocre Adsorption kinetics manages without the breakthrough an intense swell of smell when switching on the Vacuum cleaner is done. As an adsorbent material here for example activated carbon, zeolites or porous Polymers are used, these in broken / spherical form or as fibers. The size distribution, the chemical Equipment (bactericidal and fungicidal substances) and The amount of adsorbent is related to the volume of the Dust collector and to the area of application, i.e. on adapted the substances likely to be absorbed. On the one hand, this depends on one if possible efficient adsorption of unwanted odors for which the ratio of macro, meso and Micropores in the adsorbent is decisive. On the other hand application-technical criteria are also decisive. For example, the adsorbent has the invention Dust collecting space the property itself evenly to distribute in the collection room and to be as permanent as possible to be placed on the inside of the room wall. In this regard, can be further provided that these requirements filled with a very fine-grained coal are. However, other materials can also be considered such as molecular sieves in the form of a Powder. The addition of a moisture-binding can also be advantageous By means of (e.g. Selicagel) be around Living conditions of microorganisms in the dust collection room deteriorate and at the same time the adsorption performance to increase the activated carbon. In the simplest Case, it is conceivable that adsorbent in the form of particles as bulk goods before the start of a first suction process, i.e. after emptying the dust collection area sprinkle the soil to be vacuumed and into the empty one Vacuum the dust collector. The adsorbent is located then in intimate contact with the sucked in Dust, so that the smell is particularly easy to Can diffuse adsorbent. Alternatively, it can be provided be that the adsorbent in a storage container is arranged for manual emptying into the dust collection area. This is what happens after the collection room is emptied for example one with an adsorbent portion filled bag, torn open and the contained therein Adsorption material strewn into the dust collection space. This can also be done with such a portioning bag contained adsorption material on the suction Soil to be distributed. Another alternative is proposed that the adsorbent in its own air-permeable Enclosure within the dust collection area is included. The wrapper consists of one air permeable material such as a thin fleece made of paper or melt-blown. The user bring this bag before the first commissioning of the Dust collector in this one, the wrapping of the size of the adsorbent to the cross section of a Inlet opening of the dust collection space is adjusted. In this case, an area extension preferably has Wrapping a fraction of a diameter dimension the inlet opening of the dust collecting space. To continue a sufficient spatial distribution of the adsorbent in to ensure the dust collection room, it is proposed that a plurality of adsorption bags in the Dust collection spaces are contained or incorporated into them can be. In addition, it is provided that a plurality of adsorbent particles in an envelope are included. It is proposed that in a dust collector two bags with 5 grams of activated carbon each are introduced. In another alternative Design of the subject of the invention is provided that one can be opened by air flow or negative pressure Adsorbent storage container on an inner wall of the dust collector is attached. Here it can for example, one filled with the adsorbent Trade bags, which first, for example held on the inside of the inner wall of the collecting room is. Due to the air flow / negative pressure this torn or torn, after which the content through provided openings of the container in the collecting space can escape. Alternatively, such a container also be perforated, with the Switch on the vacuum cleaner this along the perforation tears off and releases the contained adsorbent. Alternatively, such a container can also be bowl-like be trained. In addition, it is conceivable that the adsorbent in one by puncturing openable storage container, for example in one Bag is arranged. According to the invention, one can first start-up of the dust collection room of the user pierce this storage container for distribution of the containing adsorbent in the collecting space. On such puncturing can also occur automatically in the course of a Collection chamber closing process take place, for example through device-side, immersed in the collecting space Appliance parts. It proves to be particularly advantageous with the Selection of the activated carbon powder adsorbent with a grain size fraction between 0.15 and 0.25 mm, the Undersize is kept small with less than 2%. Activated carbon fibers with a Diameters from 0.01 to 0.1 mm and a fiber length from 10 to 100 mm. Are also particularly effective Activated carbon powder made with coconut shells CTC values greater than 60%.

Finally, the invention relates to a Adsorbent material according to the features of claim 23. As a result of this configuration, one by one air-permeable covering enclosed adsorbent material through the entry opening into the dust collecting space or placed in the dust filter bag. From this the main advantage is that the adsorbent in the immediate vicinity of the vacuumed up dust positioned, thereby enriching a larger one Amount of odorous substances in the dust collection room or Dust filter bag is prevented because of the forming Diffuse odors continuously to the adsorbent and be bound there. In this regard, will continue proposed that the envelope be extended a fraction of a diameter dimension of the Entry opening of the dust collection space or the dust filter bag equivalent. For example, the Covering surface area of approximately one fifth to one tenth of the diameter dimension of the inlet opening correspond. For example, everyone can Adsorbent bags with three to ten grams, preferred five grams of adsorbent material, such as Activated carbon must be filled.

From the configurations according to the invention described above for filtering odors or for training a Diffusion odor filters are essential Benefits. This is how the odor filters (the adsorbent in both bag and loose form) in the difference not to a known standard adsorption filter immediately in the flow path. In addition, when using of the adsorbent in bulk on a support structure to be dispensed with, different geometrical Arrangements are conceivable. Next are the pressure drops, that of a diffusion odor filter according to the invention against the pressure drops, caused by a standard filter. A diffusion odor filter according to the invention also unfolds its effect even during standstill of the device, so that in the dust filter bag or in the dust collecting area the emergence of a larger quantity of odorants is prevented. The removal of the Support structure is with a material saving and a significantly lower process engineering effort connected in the manufacture. In addition, the adsorption performance by adding an individual chosen amount of adsorbent to his needs adaptable (e.g. odor-intensive dust from keeping pets). Furthermore, it proves to be advantageous that by the inventive design of the diffusion odor filter with every dust filter bag change or disposed of each time the dust collection area is emptied becomes. As a result, after the change / emptying an odor filter with optimized adsorption characteristics in front. Activated carbon is also a good efficiency given with a diameter smaller than 0.5 mm.

Is shown and described initially with reference to Fig. 1 is a vacuum cleaner 1 with a in a filter chamber 2 held dust filter bag 3. During operation of the vacuum cleaner 1 is schematically by means of a Motor / blower unit 4 shown in the area a suction nozzle 5 on the foot side generates a negative pressure, by means of which dust and dirt particles from which to cleaning floor 6 solved and by means of the suction air flow via a suction channel, not shown, in the Dust filter bag 3 can be transported. The motor / blower unit 4 is the dust filter bag in the air flow direction 3 downstream.

The dust picked up in the dust filter bag 3 remains there for a certain time. During this Microbiological degradation makes time different Dust ingredients produce odorant, which, as described below.

For this purpose, an adsorbent 7 in the form of activated carbon, Zeolites or porous polymer in the dust filter bag 3 entered or entered.

According to the embodiment in Fig. 1, this is Adsorbent 7 by means of a metering container 8 to the absorbent soil 6 and then sprinkled during commissioning of the vacuum cleaner 1 together with the vacuum Dust introduced into the dust filter bag 3. The dosing tank 8 has the function of a sugar sprinkler with which after a one-time tilting of the same predefined portion of the adsorbent 7 is output. The adsorption performance can, however, be determined by the user by adding an individually selected amount of adsorbent 7 (by dispensing several portions of adsorbent) adjust the needs. For example, at odor-intensive dust from keeping pets double portion of adsorbent on the floor to be sucked 6 be applied.

This adsorbent output or preferably takes place Suck up and insert the adsorbent 7 into the dust filter bag 3 once at the first start-up of the vacuum cleaner 1 after changing the dust filter bag.

2, a vacuum cleaner 1 is shown schematically, which to take up the soaked up Dirt / dust particles a separator and one after switched dust collection chamber 9. This Vacuum cleaner 1 has no, replaceable if necessary Dust filter bag according to the first embodiment on. Rather, the filled dust collecting space 9 becomes here emptied if necessary.

With this vacuum cleaner principle also results from the whereabouts of the dust collected over a certain one Period a microbiological degradation of various Dust constituents, causing the production of unwanted Smell results. In particular this results when the vacuum cleaner 1 is switched on an unpleasant initial smell surge, which according to the invention by the inclusion of adsorbent 7 in the Dust collecting space 9 is counteracted.

According to the first described with reference to FIG. 1 Embodiment is also in this second embodiment the adsorbent 7 by means of a metering container 8 sprinkled on the floor 6 to be cleaned and then together with the vacuumed up dust in the Dust collection room 9 spent.

By introducing the adsorbent 7 into the dust filter bag 3 or in the dust collection chamber 9 this in intimate contact with the sucked-in dust, so that the odorants are particularly easy to adsorb can diffuse.

3 shows a dust filter bag 3, which before first use with adsorbent 7 can be filled. This filling is similar here the previously described embodiments by means of a dosing container 8, for dispensing a predefined portion of adsorbent. The adsorbent 7 will directly into the filter bag 3 by sprinkling through the Inlet opening 10 of the dust filter bag 3 introduced. The user also has the option here by adding an individually selected amount of adsorbent 7 the adsorption properties meet his needs adapt.

In addition, the sprinkling of an adsorbent portion from the dosing container 8 also into the dust collection space of a vacuum cleaner 1 according to FIG. 2.

Alternatively, the adsorbent 7 can also be pre-portioned are available to the user, for example in the form of a portion containing an adsorbent Bag 11, which loose packed the dust filter bag 3 is. According to the representations in Figures 4 and 5 can be one that forms a storage container 13 Portion bag 11, also assigned to the dust filter bag 3 be, for example, by a detachable arrangement bag 11 on the top of the dust bag holder plate 12. The bag 11 is unmistakable for arranged the user on the holding plate 12, wherein the plan shape of the bag 11 according to the illustrated Embodiment designed similar to an arrow can be. After removing the bag 11 from the holding plate 12 can the adsorbent contained in the bag 11 through the inlet opening 10 into the dust filter bag 3 can be sprinkled. The bag 11 is along this a preferably perforated line can be torn open.

Further alternatively, the adsorbent 7 can in a storage container 13 are available.

In this respect, an exemplary embodiment is shown in FIGS. 6 and 7 shown, in which the storage container 13 bag-like with a peripheral edge 14 is formed. There is one in the shaped bag contain predetermined portion of the adsorbent 7.

The bag-like storage container 13 is covered to the inlet opening 10 of the dust filter bag holding plate 12 positioned and in the area of the rotating Edge 14 between two layers of the multi-layer holding plate 12 loosely inserted and held. Otherwise in layers bonded to one another in the usual way the holding plate 12 are in the area of the bag edge 14 holding sections are not connected. In this regard, the edge of the bag is also conceivable 14 capturing annular zones of the two, the bag-like storage container 13 clamp-fixing layers to provide a recess, for example embossing.

After inserting the dust filter bag 3 in the Vacuum cleaner 1 and then commissioning the device becomes the bag-like storage container 13 through the air flow or through that in the dust filter bag 3 negative pressure built up from the inlet opening 10 sucked into the dust filter bag 3. The adsorbent 7 can then be found in the dust filter bag 3 distribute, for which purpose the bag-like storage container 13 over a partial circumference of the peripheral edge 14 unlocked is.

As a result of this configuration, there is an automatic one Filling the dust filter bag 3 with a predefined one Adsorbent portion, which is hereafter in bulk Form in the dust filter bag 3 is present.

An alternative embodiment is shown in FIGS. 8 and 9 one fastened on the underside of the holding plate 12 Storage container 13 shown. Here is an im Floor plan of essentially rectangular storage container 13, which shows the inlet opening 10 covered on the underside of the holding plate 12. The storage container 13 is in the area between the inlet opening 10 and a narrow side edge of the holding plate 12 over the entire surface glued to the bottom of the latter. That from 15 free end of the storage container facing away from this gluing point 13 has an opening 16 which in unused condition of the dust filter bag 3 according to FIG. 9 by a material uniform on the storage container 13 tied insertion tab 17 is closed.

That containing a predefined portion of the adsorbent 7 Storage container 13 is essentially self-supporting trained such that in the unused position 9, the storage container 13 almost extends parallel to the holding plate 12.

By the pending when starting up the vacuum cleaner 1 Air flow or that in the dust filter bag 2 built up negative pressure, the storage container 13 in Pivoted towards the inside of the dust filter bag, this while sucking out the insert tab 17 to open the opening 16. The stocked Adsorbent 7 can then emerge and in the Distribute dust filter bag 3.

In this regard, it is also conceivable that the storage container 13 in the form of an open paper or film tube is formed, which is folded at the ends and fixed under the inlet opening 10 of the holding plate 12 is (for example by inserting the free End in the entry opening 10).

Another alternative to the last one Embodiment is shown in FIG. 10. Here is a storage container 13 in the form of a paper or Foil tube shown, its free, foldable The bottom of the holding plate 12 is fixed. In the illustrated embodiment, this is by a easily removable wax adhesive realized. By inserting of the suction air flow tears the free end from the wax glue 18 from to output the adsorbent 7.

Alternatively, according to FIG. 11, the storage container 13 be provided with a perforation 19. This is underneath in the form of a bag or a bag the holding plate 12, covering the inlet opening 10 all around, fixed on the edge of the mounting plate, for example glued. The perforation line is preferred in Coverage to the edge of the entry opening.

When the vacuum cleaner 1 is started up, this storage container becomes 13 by the air flow or in the Dust filter bag 3 pending vacuum along the Perforation 19 completely or only partially torn off, after which by the resulting 19 in the area of perforation Open the stored adsorbent 7 freely in the dust filter bag 3 can escape.

In general, applies to the versions in which the Storage container 13 in the form of a bag or Hose is formed that in the separated or opened storage container 13 stored adsorbent 7 emerges entirely from the storage container 13, this is supported by sucking them out of the Container in the dust filter bag 3.

For vacuum cleaners where the fluidic Connection between suction channel and dust filter bag 3 through a led through the inlet opening 10 Suction nozzle 20 is produced, the release of the in a storage container 13 stored adsorbent 7 also by destroying the storage container 13 by means of of the suction connector 20.

Such solutions are exemplified in FIGS. 12 and 13, the underside of the holding plate in FIG. 12 12, covering the inlet opening 10, a storage container 13 according to the exemplary embodiment in FIG. 11 is attached. The one when the one closes the Dust filter bag 3 receiving filter chamber 2 through entering the opening 10 of the holding plate 12 Suction nozzle 20 tears along the storage container 13 the perforation 19, after which the container in the Dust filter bag 3 falls. The stored adsorbent 7 can thereafter from the destroyed storage container 13 trickle out. Any residues in the storage container 13 are when starting up the vacuum cleaner 1 from the Container sucked out into the dust filter bag 3.

13 is a cup-like storage container 13 shown, which with a peripheral edge 21st is provided. The latter is held between two Layers of the multi-layer holding plate 12. At least one For this purpose, the position is concentric with the inlet opening 10 circumferential annular recess for receiving of the edge 21.

The cup-like one lying in the inlet opening 10 Storage container 13 contains an adsorbent supply.

This storage container 13 essentially corresponds in plan the cross section of the inlet opening 10 and is made, for example, from a paper material.

When changing the filter bag and afterwards Closing the filter chamber 2 immerses the suction nozzle 20 through the inlet opening 10 and thereby destroys it cup-like storage container 13 by this both in the area of the container ceiling 22 as well as in the area of the container bottom 23 pierces. According to this, too the stored adsorbent 7 freely in the dust filter bag 3 exit.

14 is an alternative embodiment shown, at which edge of the entrance opening 10 on the underside of the holding plate 12 a cup-like Storage container 13 is fixed, with a bottom 23, which when starting up the vacuum cleaner 1 by the Airflow or the negative pressure built up, for example tearing open or tearing along a perforation, to Release of the adsorbent 7.

Through the arrangement of a storage container described 13 in or below the holding plate, i.e. the The inside of the dust filter bag turns automatically when using for the first time with the loose Filled adsorbent. The user also has more the possibility according to the first embodiments for example by means of a dosing container 8 Adjusted to increase the dose of adsorbent.

The various filling options described of the dust filter bag 3 can be found essentially also in the dust collection chamber 9 according to FIG. 2. The Adsorbent 7 as bulk material has the particular advantage that this is in intimate contact with the sucked in Dust is there, so the odorants especially can easily diffuse to adsorbent 7.

Another possibility according to FIG. 15 is the adsorbent 7 in its own air-permeable To arrange wrapping 24. For example, here pastille-like bags with a plurality of adsorbent particles be provided.

The bags 25 thus filled with an adsorbent portion can already be installed in the dust filter bag 3 be loosely arranged. However, it is also conceivable that these bags 25 by the user before start-up the dust filter bag 3 or the dust collecting space 9 be thrown into this. For this purpose, that a surface extension a of the envelope 24 a Fraction of the diameter dimension b of the inlet opening 10 or suction port opening of the dust filter bag 3 or in the case of a vacuum cleaner according to FIG. 2 the dust collecting space 9 corresponds. For example, the area extension a of the envelope 24 about a fifth up to a tenth of the diameter dimension of the inlet opening 10 correspond.

To ensure a sufficient spatial distribution of the in the envelope 24 absorbed adsorbent 7 in the dust filter bag 3 or 9 to collect dust several small bags 25 with adsorbent 7 are provided.

Through the previously described embodiments of the Subject of the invention is the adsorbent 7 in the immediate Spent near the vacuum. It are therefore not only those during the flow of the operation of the vacuum cleaner transported to the adsorbent Odor substances eliminated. The transport takes place especially when the device is idle by diffusion of the odorants instead. The Enrichment of a large amount of odorous substances in the Dust filter bag 3 is prevented because the forming Diffuse odorant continuously to adsorbent 7 and be bound there. The diffusion odor filter thus formed comes with mediocre adsorption kinetics out without the breakthrough of a intense swell of smell when switching on the device must be feared.

Adsorbent 7, which is in bulk in the dust filter bag 3 is introduced (see FIGS. 1 to 14) has the property itself evenly in the dust filter bag 3 distribute this when the weaning is as permanent as possible the inner wall of the dust filter bag 3 or dust collection space 9. The addition can also advantageously a moisture-binding agent such as Silica gel should be provided to the living conditions of Microorganisms in the dust filter bag 3 or in the dust collection room 9 deteriorate and at the same time the adsorption performance to increase the adsorbent 7.
