Description

The invention relates to an initially dust filter bag for a vacuum cleaner or a dust collection room of a vacuum cleaner. The invention relates In addition, in an air-permeable envelope recorded Adsorbent material.

There are vacuum cleaners which have a dust filter bag in which the Dust is first taken when performing the vacuum cleaning. Next there are vacuum cleaners, where the dust, about one Cyclone separator, immediately in one without removable Dust filter bag provided dust collection space is entered.

Furthermore, it is known that when using a vacuum cleaner, especially at a repeated switching on, one perceived as unpleasant Odor development can occur. For odor adsorption it is known Use absorption filter, the main components of the adsorbent for Binding of the odorants and a suitable carrier material for fixation of the adsorbent are. As adsorbent highly porous materials are used, in many cases z. As activated carbon used. But there are others too Materials such as e.g. Zeolites or porous organic polymers use. The adsorbent consists mostly of particles in different forms and size fractions may be present. These are using different Carrier structures, such as foam, fabric, fleece, honeycomb, etc. in a defined manner distributed over the filter. Such an odor filter is so in the device arranged that this during operation of the device of the flowed through air is conveyed. In general, such a filter is on the Suction side located in front of the blower, bringing the adsorption balance in the filter not due to the elevated temperature after the motor-blower unit is negatively influenced. Furthermore, it is known for the purpose of Covering an unpleasant smell porous, soaked with perfumes Use media in room air cleaners and vacuum cleaners. Here are Sticks and granules are known, which are introduced into a filter bag or also be installed in the flow path of the air. The deposition of Odors in a vacuum cleaner makes specific demands. Different as e.g. in a room air purifier is in a vacuum cleaner the Collected dust in a dust filter bag or another retained and collected special dust collection container. Of the absorbed dust remains in this filter bag for a certain time or container. During this time is due to the microbiological degradation different dust constituents a large part of the undesirable odors produced. In the case of a vacuum cleaner, the main disadvantage of known solutions now that the deposition of odors in Essentially during operation of the vacuum cleaner is done by the Odors by convective transport with the flowing air in the Enter odor filter. For one, it causes the associated Flow through the filter an undesirably high pressure loss. On the other hand requires the sudden onset of the vacuum cleaner high concentration of odorous substances in the suction air a very good Adsorption kinetics of the filters.

From US-A 5 461 751 it is known cedar wood chips as air freshener and To introduce pesticides into a dust filter. The Releases of the cedar wood at the same time have a scent covering effect and schädlingbekämpfend. Similarly, it is known from FR-A-2 417 287 known, bactericidal, fungicidal and odorous substances in one Introduce dust filter bag. WO 94/21305 A deals with a free-flowing means for air improvement as such and proposes this one Combination of a sand and fragrance in front. The previously known Objects themselves each contain odor-releasing substances. These are also effective during standstill of a vacuum cleaner. At the Turning on a vacuum cleaner will increase in the dust filter bag accumulated odoriferous substances released and lead to a not always considered to be an advantageous odor load.

In view of the above-described prior art, the task of To see therein a dust filter bag for a vacuum cleaner or a dust collection room of a vacuum cleaner or one in an air-permeable one Enclosure containing adsorbent material indicate which or which taking into account a low pressure loss in particular one after switching on the vacuum cleaner suddenly incipient odor can be prevented.

This task is initially and essentially in terms of Dust filter bag or the dust collection chamber in the objects of Claims 1, 2, or 7 and with respect to the adsorbent in the subject matter of Claim 17 solved.

It is important that in the dust filter bag or in the Staubsammelraum an adsorbent is present in bulk or that one Adsorbent in an outside of the dust bag or the Dust-collecting space attached storage container is arranged for filling the dust filter bag with adsorbent or that the adsorbent in one Adsorbent storage container in the dust filter bag or in the Staubsammelraum exists and in the course of vacuuming from the Reservoir is sucked out or that placed in the Dust filter bag or the dust collection room a bag with one present in portions adsorbent for odor adsorption, which filled adsorbent can then be contained in an enclosure, in size to the cross section of the inlet opening of a Staubsammelraums a vacuum cleaner or a dust filter bag for a Vacuum cleaner is adjusted.

As a result, odors can be bound at the place of their formation become. This happens because the adsorbent is in the immediate vicinity the sucked dust is introduced. The amount of adsorbent can be comparatively low, for example between 3 and 30g, preferably between 5 and 50g per usual dust collection room. The adsorbent is in particular in Form of loosely introduced and registered adsorbent granules before. The Odors are not only affected by the flow during operation of the Vacuum cleaner transported to the adsorbent. Rather, the transport takes place especially in the times in which the device is stationary, by diffusion of Odors take place. Advantageously, omitted by the proposed Invention, the pressure loss of a filter, which during operation of the Device is flowed through by the air. Furthermore, the enrichment a larger amount of odors in the dust filter bag or the Dust collector prevents, as the forming odors continuously diffuse to the adsorbent and bound there. This As a result, in contrast to the known odor filters no relative large amount of odorants must be adsorbed in a short time. One According to the invention diffusion odor filter comes with a mediocre adsorption kinetics without the breakthrough of a intense odor when switching on the device. At the Vacuuming the odor molecules are eliminated, which immediately after be turned off the device. The adsorbent can open different way entered directly into the dust collection room or be registered. So it is conceivable, for example, that before the beginning of a first suction or at the beginning of each suction that Adsorbent in the dust collection room, possibly in the dust filter bag is introduced. In this regard, it may be provided that the adsorbent such as activated carbon, which in fracture / spherical form or as fibers present, packed in portions in a bag, which bag by the user before using the dust filter bag for the first time or the dust collecting space can be introduced into this. Such a Adsorbent bag is made of a highly breathable material such as for example, a thin web of paper or melt-blown. At this method, a sufficient spatial distribution of the adsorbent in the Dust collection or in the dust filter bag is to achieve suggested that several smaller bags with adsorbent introduced be, for example, two bags each with 5 grams of activated carbon. In a Alternative embodiment provides that the adsorbent in loose form in the dust collecting space or dust filter bag is present. This turns out to the effect that the adsorbent in intimate contact with The suctioned dust is located so that the odors are particularly light can diffuse to the adsorbent. For example, the user can by means of a dosing a predetermined amount of adsorbent through the Filling opening of the dust filter bag or in the dust collection room contribute. Alternatively, the adsorbent in the form of activated carbon also present in portions in bags. The user can therefore before beginning a first suction, i. after inserting a new one Dust filter bag or after emptying the dust collection room a fill in pre-defined portion of adsorbent. Further alternatively, it is provided that the adsorbent is applied to the soil to be sucked and together with the absorbed dust in the dust collection chamber or the Dust filter bag is introduced. So the adsorbent is in the form of Particles as bulk material in an empty dust filter bag or Sucked in dust collecting room. Again, it is conceivable that adsorbent by means of a dosing container for the predefined dispensing of an adsorbent portion to sprinkle on the absorbent soil. Further alternatively, it is provided that the adsorbent in a storage container in the dust collection chamber or present in the dust filter bag and in the course of vacuuming from the Reservoir is sucked out. For example, in the field of Suction air inlet opening of the dust filter bag or the dust collection chamber an open-edge bag or a cup-shaped container to be arranged, from which when first putting the vacuum cleaner after a Dust filter bag change or after emptying the dust collection chamber or in the course of closing the dust collecting space or the Dust filter bag receiving filter chamber the adsorbent in the Dust filter bag or the dust collection chamber is introduced. Here it is conceivable that by at least partial destruction of the storage bag or of the container, the adsorbent for distribution in the room independently exit. Furthermore, solutions are conceivable in which a container with one through the suction air stream or through the in the dust collection room or the dust filter bag prevailing negative pressure in one of the adsorbent releasing open position is provided movable lid.

According to the embodiment of in the dust filter bag or in the Dust collecting space located adsorbent in loose form, is the Adsorbent in intimate contact with the sucked dust, so that the Odors particularly easy to diffuse to the adsorbent. according to the odors are bound to their place of origin. in this connection it proves to be particularly advantageous that such a diffusion odor filter inside the dust filter bag with a mediocre Adsorption kinetics does not require the breakthrough of an intense Odor swath when switching on the vacuum cleaner. As adsorbent material Here, for example, activated carbon, zeolites or porous Polymers are used, these in fracture / spherical or as fibers. The Size distribution, the chemical equipment (bactericidal and fungicidal Substances) and amount of adsorbent is related to the uptake volume of the Dust bag and to the field of application, i. to the expected Adjusted substances to be absorbed. Here it comes further to one on the most efficient adsorption of unwanted Odorants for which the ratio of macro, meso- and micropores in the Adsorbent is relevant. On the other hand, application-related Criteria prevail. For example, the adsorbent of the dust filter bag according to the invention the property of being uniform in distribute the bag and stay as long as possible on the inside of the bag Settle bag wall. In this regard, it can be further provided that these requirements are met by a very fine-grained charcoal. It However, other materials come into consideration, such as Molecular sieves in the form of a powder. Advantageously, the addition of a moisture binding agent (e.g., silica gel) to prevent the Deteriorate living conditions of microorganisms in the anther and at the same time increase the adsorption capacity of the activated carbon. in the In the simplest case, it is conceivable to use the adsorbent in the form of particles Bulk material before the beginning of a first suction, i. after renovation the dust filter bag, to sprinkle on the soil to be sucked and in the suck in empty dust filter bag. The adsorbent is hereafter in intimate contact with the aspirated dust, leaving the odors particularly easy to diffuse to the adsorbent. Alternatively, you can be provided that the adsorbent in an outside of the Dust filter bag attached storage container is arranged for manual emptying in the dust filter bag. So when inserting a new Staubfilterbeutels in the vacuum cleaner, for example, one, with a Adsorption material portion filled bag, which further example, on the retaining plate of the dust filter bag is removably fixed, removed and torn to the adsorption material contained therein through the Intake opening into the dust filter bag einustreuen. Such Portioning bag can also be assigned in loose form the dust filter bag, whereby the user has the possibility of containing it Adsorb material directly into the dust filter bag or on the distribute soil to be sucked off. Further alternatively, it is suggested that the adsorbent in its own, air-permeable envelope within the Dust filter bag is included. The wrapper consists of one air-permeable material such as a thin fleece of paper or melt-blown. Such an adsorbent bag can already factory in the Be introduced dust filter bag. However, there is also the possibility Such an adsorbent bag loose or removable on the support plate the Assign dust filter bag. The user brings this bag Initial start - up of the dust filter bag through the inlet opening in this one, wherein the envelope of the adsorbent in size to the Cross section of the inlet opening of the dust filter bag is adjusted. In this case, an areal extent of the enclosure preferably has one Fraction of a diameter dimension of the inlet opening of On the dust filter bag. To continue a sufficient spatial distribution of To ensure adsorbent in the dust filter bag, it is proposed a plurality of adsorbent bags are contained in the dust filter bag are or can be introduced into these. It is also envisaged that each containing a plurality of adsorbent particles in an enclosure are. Thus, it is proposed that in a dust filter bag, two bags each 5 grams of activated carbon are introduced. In another alternative Embodiment of the subject invention is provided that a by Air flow or vacuum openable adsorbent storage container on a Inner wall of the dust filter bag is attached. So, one can, first extending over the filling opening of the dust filter bag Reservoir be provided, which at the first switching on the Vacuum cleaner after a dust filter bag change by the air flow or the pressure prevailing in the dust filter bag from the Inlet opening is torn into the interior of the dust filter bag. Here can it is for example a bag filled with the adsorbent, which is initially held close to the edge in the region of the inlet opening. By the air flow / negative pressure is this from the inlet area torn, after which the contents through openings provided in the container in can escape the bag interior. Alternatively, such a container also be formed perforated, wherein when switching on the vacuum cleaner this tears off along the perforation and releases the contained adsorbent. Next alternatively, such a container and cup-like, the Inlet cross-section of the dust filter bag initially formed occlusive be. In addition, it is also conceivable, a container below the retaining plate to arrange close to the filling opening. For example, underside the holding plate an annular, the filling opening enclosing container be provided, which by the air flow or the upcoming Negative pressure when switching on the vacuum cleaner to release the adsorbent is torn off from the holding plate and in which by inserting the Air flow or the negative pressure, the adsorbent in the container retaining lid or the like in a releasing the adsorbent Position is shifted. In addition, there is a possibility that the Adsorbent in a rupture-openable storage container, For example, in a bag, in overlap to the suction port opening the dust filter bag is arranged. According to the invention, a first Commissioning the dust filter bag the user of this storage container pierced, for distributing the containing adsorbent in the dust filter. Preferably, this embodiment is used there, in which a airflow with a suction port connected suction at a Closing the dust filter bag holding filter chamber through the Suction port opening of the dust filter bag holding plate steps. Accordingly, in the This filter chamber closing process in overlapping to the Suction nozzle opening arranged adsorbent storage container of the Punctured suction and thus opened, for release and distribution of Adsorbent in the dust filter bag. Particularly advantageous proves in the Selection of adsorbent activated carbon powder with a particle size fraction between 0.15 and 0.25 mm, with the undersize fraction being less than 2% kept small. Also very advantageous are activated carbon fibers with a Diameter of 0.01 to 0.1 mm and a fiber length of 10 to 100 mm. Particularly effective are also made of coconut shells Activated carbon powder with CTC values greater than 60%.

Concerning the dust collecting space, the adsorbent is in the Dust collection room in loose form. Such vacuum cleaners are known, wherein here the absorbed dust in the filterless system in the plenum is deposited. The filled collection space is for emptying of the Device housing removable. According to the embodiment of the invention is the adsorbent in intimate contact with the sucked-in dust, so that the odors are particularly easy to diffuse to the adsorbent can. As a result, the odors are at the place of their formation bound. It proves to be particularly advantageous that such a Diffusion odor filter inside the dust collection room with a mediocre adsorption kinetics, without the breakthrough of a intense odor when switching on the vacuum cleaner. When Adsorbent material can here, for example, activated carbon, zeolites or porous Polymers are used, these in fracture / spherical or as fibers. The Size distribution, the chemical equipment (bactericidal and fungicidal Substances) and the amount of adsorbent is related to the uptake volume of the Staubsammelraumes and to the application area, i. to the presumably absorbed substances. This is where it comes from Furthermore, on the one hand to the most efficient adsorption of undesirable odorants, for which the ratio of macro, meso Micropores in the adsorbent are relevant. For another, too application criteria prevail. For example, this has Adsorbent of the dust collection chamber of the invention, the property evenly distributed in the dust collection room and as possible permanently settle on the inside of the room wall. In this regard, can be further provided that these requirements of a very fine-grained coal are met. But there are others too Materials such as molecular sieves in the form of a Powder. Advantageously, the addition of a moisture-binding Using (e.g., silica gel) to control the living conditions of microorganisms in the dust collection room to worsen while the To increase the adsorption capacity of the activated carbon. In the simplest case it is conceivable, the adsorbent in the form of particles as bulk material before the beginning of a first suction, i. after emptying the dust collection room, to litter on the z-sucking ground and into the empty dust-collecting room suck. The adsorbent is then in intimate contact with the sucked dust, so that the odors are particularly easy to Adsorbent can diffuse. Alternatively it can be provided that the Adsorbent is placed in a storage container for hand-Entlerrung in the dust collection room. So after emptying the plenum for example, a bag filled with an adsorbent material portion, torn open and the adsorption material contained therein in the Staubsammelraum sprinkled, by means of such a portioning bag can also the adsorption material contained therein on the soil to be sucked off be distributed. Further alternatively, it is proposed that the adsorbent in an own, air permeable wrapping within the Dust collection room is included. The wrapper consists of one air-permeable material such as a thin fleece of paper or melt-blown. The user brings this bag before the first time Commissioning the dust collection room in this one, the enclosure of the adsorbent in size to the cross section of an inlet opening of the Dust collecting space is adjusted. In this case, a preferred Areal extent of serving a fraction of a Diameter dimension of the inlet opening of the dust collection chamber. Around Furthermore, a sufficient spatial distribution of the adsorbent in the To ensure dust collection, it is suggested that a majority of adsorption bags are contained in the dust collecting space or in this can be introduced. In addition, it is provided that each one A plurality of adsorbent particles are contained in an enclosure. So will suggested that in a dust collection room two bags of 5 grams each Activated carbon are introduced. In a further alternative embodiment of the Subject of the invention is provided that a by air flow or Vacuum openable adsorbent storage container on an inner wall of the Dust collection room is attached. This may, for example, to a bag filled with the adsorbent, which first for example, is held on the inside of the plenum inner wall. By the air flow / negative pressure this is off or torn open, after which the contents through openings provided for the container can escape into the collection room. Alternatively, such a container also be formed perforated, wherein when switching on the vacuum cleaner this tears off along the perforation and releases the contained adsorbent. Further, such a container may also be formed cup-like. About that In addition, it is also conceivable that the adsorbent in a by piercing openable storage container, for example, is arranged in a bag. According to the invention, prior to a first start-up of the Dust collecting the user of this storage container pierced, for Distribution of the containing adsorbent in the collecting space. Such Piercing can also be done automatically in the course of a collection chamber closing process be done, for example, by the device side, in the Plenum dipping equipment parts. Particularly advantageous proves the selection of the adsorbent activated carbon powder with a particle size fraction between 0.15 and 0.25 mm, with the undersize fraction being less than 2% kept small. Also very advantageous are activated carbon fibers with a Diameter of 0.01 to 0.1 mm and a fiber length of 10 to 100 mm. Particularly effective are also made of coconut shells Activated carbon powder with CTC values greater than 60%.

Further regarding the design of the in an air-permeable envelope, such as nonwoven fabric, contained adsorbent material, wherein the Envelope in size at the cross section of the inlet opening of the Staubsammelraumes or dust filter bag is adapted: According to this Embodiment may be enclosed by an air-permeable enclosure Adsorbent material through the inlet opening in the dust collection chamber or be introduced into the dust filter bag. This results in the significant advantage that the adsorbent in the immediate vicinity of sucked up dust, thereby enriching a larger Amount of odorants in the dust collection chamber or dust filter bag is prevented, since the forming odors continuously for Adsorbent diffuse and bound there. This will be further proposed that an areal extent of the envelope a Fraction of a diameter dimension of the inlet opening of the Dust collecting space or the dust filter bag corresponds. So can For example, the areal extent of the envelope about one-fifth to one tenth of the diameter dimension of the inlet opening correspond. For example, each adsorbent bag of 3 to 30 grams, preferably 5 grams of adsorbent material, such as activated carbon be filled.

From the above-described embodiments of the invention for Odor filtering or to form a diffusion odor filter result significant advantages. So are the odor filter (the adsorbent both in Bag as well as in loose form) in contrast to a known standard adsorption filter not directly in the flow path. In addition, at the Use of the adsorbent in bulk on a support structure omitted be, with various geometric arrangements are conceivable. Further are the pressure losses of a diffusion odor filter according to the invention caused, compared to the pressure losses, caused by a standard filter to neglect. Further unfolded an inventive diffusion odor filter its effect even during the standstill of the device, so that in the dust filter bag or in the Dust collecting the emergence of a larger amount of odors is prevented. The omission of the support structure is with a material savings and a considerably lower process complexity in the Associated production. In addition, the adsorption performance of the user by adding an individually selected amount of adsorbent to his Needs adaptable (e.g., odor-intensive dust by pet ownership). Furthermore, it proves to be advantageous that by the inventive Design of the diffusion-type filter with every dust filter bag change or is disposed of with each emptying of the dust collecting space. As a result, is located after changing / draining an odor filter with optimized Adsorption characteristic before. A good efficiency is also included Activated carbon with a diameter smaller than 0.5 mm given.

First shown and described with reference to FIG. 1 is a vacuum cleaner 1 with a dust filter bag 3 held in a filter chamber 2. During the Operation of the vacuum cleaner 1 is by means of a schematically illustrated Motor / fan unit 4 in the region of a foot-side suction nozzle 5 a Vacuum generated by means of which dust and dirt particles from the cleaning soil solved 6 and by means of the suction air flow over a not shown suction channel are transported into the dust filter bag 3. The Motor / blower unit 4 is in the air flow direction to the dust filter bag 3 downstream.

The dust collected in the dust filter bag 3 remains there for one certain time. During this time will be through the microbiological Degradation of various dust ingredients odorant produced, which, like to be adsorbed below.

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

According to the exemplary embodiment in FIG. 1, the adsorbent 7 is used for this purpose a dosing 8 sprinkled on the bottom 6 to be sucked and hereafter when putting the vacuum cleaner into operation together with the absorbed dust introduced into the dust filter bag 3. The metering 8 has the function a sugar spreader, which after a single tipping the same a predefined portion of the adsorbent 7 is dispensed. The However, adsorption performance can be achieved by the user by adding a individually selected amount of adsorbent 7 (by issuing several Adsorbent ads) to suit the needs. For example, at odor-intensive dust through pet ownership a double adsorbent serving be applied to the soil to be sucked 6.

Preferably, this adsorbent output or the absorption and Introducing the adsorbent 7 in the dust filter bag 3 once at the first Commissioning of the vacuum cleaner 1 after a dust filter bag change.

In Fig. 2, a vacuum cleaner 1 is shown schematically, which for receiving the absorbed dirt / dust particles a separator and a Hereinafter switched dust collection chamber 9 has. This vacuum cleaner 1 has no, if necessary interchangeable Staubfilterbeuel according to the first Ausführungsbesipiel on. Rather, here is the filled dust collection space. 9 emptied when needed.

Also in this vacuum cleaner principle results from the whereabouts of the absorbed dust over a period of time microbiological degradation of various dust constituents, causing the production of undesirable odors. Especially when Turning on the vacuum cleaner 1 results in an unpleasant initial odor surge, which according to the invention by the inclusion of Adsorbent 7 is counteracted in the dust collection chamber 9.

According to the first embodiment described with reference to FIG in this second embodiment, the adsorbent 7 by means of a Dosierbehälters 8 sprinkled on the floor to be cleaned 6 and thereafter together with the sucked-up dust into the dust collecting space 9 spent.

By introducing the adsorbent 7 in the dust filter bag 3 and in the Staubsammelraum 9 is this in intimate contact with the sucked dust, so that the odors particularly easy to adsorbent can diffuse.

In Fig. 3, a dust filter bag 3 is shown, which before a first Use can be filled with adsorbent 7. This filling takes place here similar to the embodiments described above by means of a Dosing container 8, for dispensing a predefined adsorbent portion. The Adsorbent 7 is placed directly in the filter bag 3 by sprinkling through the Inlet opening 10 of the dust filter bag 3 introduced. Also here has the Users the opportunity by adding an individually selected quantity Adsorbent 7 to adapt the adsorption to his needs.

In addition, the sprinkling of an adsorbent portion from the Dosing 8 also in the dust collection chamber of a vacuum cleaner 1 according to Fig. 2 done.

As an alternative, the adsorbent 7 can also be pre-portioned to the user for Available, such as in the form of a, an adsorbent portion containing bag 11, which is loosely packed with the dust filter bag 3. As shown in Figures 4 and 5, such, a Storage container 13 forming portion bag 11 and the dust filter bag. 3 be assigned, so for example by a detachable arrangement of the bag 11th on the top of the dust filter bag retaining plate 12. The bag is unmistakably arranged for the user on the holding plate 12, wherein the Floor plan shape of the bag 11 according to the illustrated embodiment may be formed similar to a pointer arrow. After the decrease of Bag 11 of the holding plate 12, the adsorbent contained in the bag 11 are sprinkled through the inlet opening 10 in the dust filter bag 3. The Bag 11 can be torn open along a preferably perforated line.

Further alternatively, the adsorbent 7 in a storage container 13 for To be available.

FIGS. 6 and 7 show an embodiment in this regard, in which the storage container 13 bag-like with a peripheral edge 14 is formed. In the bag thus formed is a predetermined portion of the adsorbent 7 included.

The bag-like storage container 13 is in overlap to the inlet opening 10 of the dust filter bag holding plate 12 is positioned and in the region of circumferential edge 14 between two layers of the multilayer retaining plate 12th loosely inserted and held. The otherwise usual way with each other adhesive-bonded layers of the holding plate 12 are in the area of the Bag edge 14 holding sections not connected to each other. In this regard, it is further conceivable that the bag edge 14, annular zones of the two, the bag-like storage container 13th clamp-fixing layers with a depression, for example embossing, too Mistake.

After insertion of the dust filter bag 3 in the vacuum cleaner 1 and Thereafter, the commissioning of the device becomes the bag-like Reservoir 13 by the air flow or by in the Dust filter bag 3 built vacuum from the inlet opening 10 in the Dust filter bag 3 sucked. The adsorbent 7 can be found hereinafter in the Distribute dust filter bag 3, including the bag-like storage container 13 via a partial circumference of the peripheral edge 14 is unlocked.

As a result of this embodiment, an automatic filling of the Dust filter bag 3 with a predefined adsorbent portion, which hereinafter in loose form in the dust filter bag 3 is present.

In the figures 8 and 9, an alternative embodiment of a lower side of Holding plate 12 attached storage container 13 shown. Here is an im Floor plan substantially rectangular storage container 13 shown, which covers the inlet opening 10 on the underside of the retaining plate 12. The Reservoir 13 is in the area between the inlet opening 10 and a Narrow side edge of the holding plate 12 over its entire surface at the bottom of the latter glued. The remote from this splice 15 free end of the Reservoir 13 has an opening 16, which in the unused Condition of the dust filter bag 3 of FIG. 9 by a material of the same the storage container 13 attached tuck 17 is closed.

The pre-defined portion of the adsorbent 7 containing storage container 13 is formed substantially self-supporting such that in the unused position shown in FIG. 9, the storage container 13 is almost extends parallel to the holding plate 12.

By the pending at startup of the vacuum cleaner 1 air flow or the vacuum built up in the dust filter bag 3 becomes the Reservoir 13 swung towards the dust filter bag interior, this with simultaneous sucking out of the tuck 17 to release the Opening 16. The stored adsorbent 7 can then emerge and move into distribute the dust filter bag.

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

Another alternative to the last described embodiment is shown in FIG. 10. Here is a storage container 13 in the form of a Papieroder Foil tube shown, the free, hinged end underside the holding plate 12 is fixed. in the illustrated embodiment this is realized by an easily detachable wax adhesive. By inserting the Saugluftstromes tears the free end of the wax adhesive 18 from the issue of the adsorbent 7.

Next alternatively, as shown in FIG. 11, the storage container 13 with a Be perforation 19 provided. This is in the form of a bag or a bag on the underside of the holding plate 12, the inlet opening 10 overlapping circumferentially, fixed plate edge side, for example, glued. The perforation line is preferably in coverage to the inlet opening edge.

When putting the vacuum cleaner 1 of this storage container 13 through the air flow or in the dust filter bag 3 pending vacuum completely or even partially demolished along the perforation, after which the resulting in the perforation 19 openings stockpiled Adsorbent 7 can escape freely into the dust filter bag 3.

In general, for the embodiments in which the storage container 13 is formed in the form of a bag or a hose that in the separated or opened storage container 13 stored adsorbent. 7 completely exits the storage container 13, this supported by the Aspirate the same from the container in the dust filter bag. 3

For vacuum cleaners, in which the fluidic connection between Suction channel and dust filter bag 3 through a through the entrance 10th guided suction can be made, the release of the in one Reservoir 13 stockpiled adsorbent 7 by destruction of the Reservoir 13 done by means of the suction nozzle 20.

Such solutions are exemplified in Figs. 12 and 13, wherein in Fig. 12 on the underside of the holding plate 12, the inlet opening a covering Storage container 13 according to the embodiment in Fig. 11 is attached. The at a closing of the dust filter bag 3 receiving Filter chamber 2 passing through the inlet opening of the holding plate 12 Suction nozzle tears off the storage container 13 along the perforation 19, after which the container falls into the dust filter bag 3. The stored Adsorbent 7 can then trickle out of the destroyed storage container 13. Any residues in the storage container 13 are at startup of the Vacuum cleaner 1 sucked out of the container into the dust filter bag 3.

In Fig. 13, a cup-shaped storage container 13 is shown, which with a circumferential edge 21 is provided. The latter is held between two layers the multilayer holding plate 12. At least one layer has this one concentric with the inlet opening 10 circumferential annular recess for Recording of the edge 21.

The in the inlet opening 10, cup-like storage container 13th includes an adsorbent supply.

This storage container 13 corresponds essentially to the floor plan of Cross-section of the inlet opening 10 and is for example made of a Paper material produced.

In a filter bag change and then closing the closing Filter chamber 2 dives the suction nozzle 20 through the inlet opening 10 and destroys the cup-like storage container 13 by this this both in Area of the container ceiling 22 and in the area of the container bottom 23rd pierces. Here, too, can thereafter the stored adsorbent 7 free in the Dust filter bag 3 emerge.

Furthermore, an alternative embodiment is shown in FIG which close to the inlet opening 10 on the underside of the holding plate 12 a cup-shaped container 13 is fixed, with a bottom 23, which at Commissioning of the vacuum cleaner by the air flow or the built For example, negative pressure on or breaks off along a perforation, to Release of the adsorbent 7.

By the described arrangement of a storage container 13 in or below the holding plate, i. facing the dust filter bag interior, is the latter automatically at a first startup with the loose adsorbent filled. The user also has the option according to the first exemplary embodiments, for example by means of a metering container 8 adapted to his needs to increase the adsorbent dose.

The described different ways of filling the Dust filter bag 3 find essentially in the dust collection chamber. 9 as shown in FIG. 2 application. The adsorbent 7 as bulk material has in particular the Advantage that this in intimate contact with the sucked dust so that the odors are particularly easy to adsorbent 7 can diffuse.

Another possibility is shown in FIG. 15 therein, the adsorbent 7 in a own, air-permeable envelope to arrange. For example, you can here pastille-like bag with a plurality of adsorbent particles be provided.

The so filled with an adsorbent serving bag 25 factory already be loosely arranged in the dust filter bag 3. It is, however conceivable that these bags 25 by the user before putting the Dust bag 3 and the dust collection chamber 9 thrown into this become. For this purpose, it is provided that a surface extension a of the envelope 24 a fraction of the diameter dimension b of the inlet opening 10 or Suction nozzle opening of the dust filter bag 3 or in a vacuum cleaner 2 corresponds to the dust collection chamber 9. For example, the Areal extent a of the envelope 24 about one fifth to one tenth the diameter dimension of the inlet opening 10 correspond.

In order to achieve a sufficient spatial distribution of the in the enclosure 24 absorbed adsorbent 7 in the dust filter bag 3 or To ensure dust collecting 9, are several small bag 25 with Adsorbent 7 provided.

By the embodiments of the above-described Subject of the invention is the adsorbent 7 in the immediate vicinity of the spent sucked up dust. It is therefore not just the by Flow during operation of the vacuum cleaner to the adsorbent transported odors eliminated. The transport takes place especially in the times when the device is stopped by diffusion of the odors instead of. Enrichment of a larger amount of odorous substances in the Dust filter bag 3 is prevented because the forming odors continuously diffuse to the adsorbent 7 and bound there. Of the thus formed diffusion odor filter comes with a mediocre Adsorption kinetics off without the breakthrough of an intense Odor cloud must be feared when switching on the device.

Adsorbent 7, which is introduced in loose form in the dust filter bag 3 (see. Fig. 1 to 14) has the property to be uniform in the dust filter bag 3 distribute this, as long as possible settling on the inner wall of the Dust filter bag 3 and Staubsammelraumes 9. Advantageously, can also the addition of a moisture-binding agent such as Silica gel can be provided to the living conditions of microorganisms deteriorate in the dust filter bag 3 or in the dust collection chamber 9 and at the same time to increase the adsorption capacity of the adsorbent 7.
