Abstract

The invention relates to a method for vacuum cleaning using a hand vacuum cleaner (1). The dust is first collected in a dust collection container (9), for example a dust filter bag (3), and then disposed of. An adsorbent (7), for example activated carbon, is also provided for adsorbing odours. The invention also relates to a dust filter bag (3) or dust collection compartment (9) for a vacuum cleaner (1). The aim of the invention is to improve a method and a dust filter bag (3) or a dust collection compartment (9) of this type in terms of advantageously preventing or reducing the initial odour surge. To this end, the adsorbent (7) is introduced directly into the dust collection compartment (3, 9) and an adsorbent (7) is provided in the dust filter bag (3) or the dust collection compartment (9) in a loose form.

Description

00001 Method for vacuuming with a handheld vacuum cleaner,

00002 and dust filter bags or dust bags

00003 space, in particular for use in such

00004 method 00005

00006 The invention initially relates to a method for dust

00007 vacuum with a hand vacuum cleaner, whereby the dust

00008 next in a dust collector, for example

00009 a dust filter bag, is picked up and subsequently

00010 is disposed of, whereby also an odor adsorber

00011 be carried out by means of an adsorbent, for example

00012 activated carbon. 00013

Methods of this type are known, whereby

Sorbing adsorption filters are used, the

00016 main components of the adsorbent for binding the odor

00017 fabrics and a suitable carrier material for fixation

00018 of the adsorbent are. As an adsorbent become highly porous

00019 materials are used, in many cases e.g.

00020 activated carbon used. But there are also other materials

00021 materials such as Zeolites or porous organic polymers

00022 re use. The adsorbent mostly consists of parti-

00023 none that come in different shapes and sizes

00024 NEN can be present. With the help of various

00025 ner support structures such as foam, fabric, fleece, honeycomb

00026 etc. distributed in a defined manner over the filter. On

00027 such odor filter is arranged in the device

Net that this during the operation of the device of

00029 of the conveyed air is flowed through. Usually is

Such a filter on the suction side in front of the blower

Arranged, whereby the adsorption equilibrium in

00032 filter is not due to the increased temperature after the

00033 motor-blower unit is negatively affected. The wide

00034 ren is known for the purpose of covering one

00035 unpleasant smell porous, soaked with fragrances 00036 media to be used in room air cleaners and vacuum cleaners

00037 zen. Here sticks and granules are known, which in

00038 a filter bag can be introduced or also in the flow

00039 path of the air can be attached. The deposition

00040 of odorous substances in a vacuum cleaner provides special

00041 fish requirements. Unlike e.g. in a room air

00042 cleaner is taken in a vacuum cleaner

00043 Dust in a dust filter bag or another

00044 special dust collection container retained and

00045 melt. The dust collected remains for a certain

00046 th time in this filter bag or container. While

00047 this time is due to microbiological degradation

00048 different dust constituents a large part of the un-

00049 desired odorants produced. in case of a

00050 vacuum cleaner there is the main disadvantage of the

Solutions known 00051 now in that the deposition of the

00052 odorous substances essentially during the operation of the

00053 vacuum cleaner is made by the odorous substances

00054 convective transport with the flowing air in the

00055 odor filter. For one thing, it causes it

00056 associated flow through the filter an undesirable

00057 high pressure loss. On the other hand, it demands the

00058 switching on the vacuum cleaner suddenly high

00059 concentration of odorous substances in the suction air a

00060 very good absorption kinetics of the filters. 00061

00062 With regard to the state of the art

00063 nik becomes a technical problem of the invention

00064 first seen in a method for vacuuming

00065 with a handheld vacuum cleaner in an advantageous manner

00066 so that, taking into account a slight

00067 against pressure loss, especially after switching on

00068 th of the vacuum cleaner suddenly starting odor

00069 gush is prevented. 00070 00071 This problem is first and foremost

00072 with regard to the method for the subject of the claim

00073 ches 1 solved, the focus being on that

00074 adsorbent entered directly into the dust collection space

00075 or is entered. As a result of this configuration

00076 specified a method in which the odorous substances

00077 be bound at the place of their creation. this happens

00078 in that the adsorbent in the immediate vicinity of

00079 dust is introduced. The amount of

00080 adsorbent can be comparatively small, for example between

00081 3 and 30g, preferably between 5 and 50g depending on the usual

00082 dust collection room. The adsorbent is particularly

00083 re of loosely introduced or entered adsorbent

00084 granules. The scents are not only due to the

00085 flow during the operation of the vacuum cleaner for

00086 adsorbent transported. Rather, the transport takes place

00087 especially in times when the device is

00088 is held by diffusion of the odorous substances. In

00089 advantageously eliminated by the proposed

00090 invention the pressure loss of a filter, which

00091 rend of the operation of the device through which the air flows

00092 will. Furthermore, enriching a larger one

Quantity of odor substances in the dust filter bag or in

00094 prevents the dust collection container because the

00095 the odorants continuously diffuse to the adsorbent

00096 and be bound there. As a consequence,

00097 that, in contrast to the known odor filters, none

00098 relatively large amount of odorants in a short time

00099 must be adsorbed. A diffuser according to the invention

00100 ons odor filter therefore comes with a medium

00101 adsorption kinetics without the breakthrough of a

00102 intense swell of smell when switching on the device

00103 is done. By the method according to the invention

00104 eliminates the odor molecules when vacuuming, which

00105 immediately after switching on the device 00106 gene. The adsorbent can be used in various

00107 ren entered directly in the dust collection or

00108 can be entered. For example, it is conceivable

00109 that before the start of a first suction or at

00110 start of each suction process the adsorbent in the dust

00111 collecting space, possibly in the suction filter bag

00112 is introduced. In this regard, it can be provided

00113 that the adsorbent such as activated carbon, which

00114 in broken / spherical form or as fibers, in portions

00115 filled in a bag, which bag

00116 tel by the user before first use

00117 of the dust filter bag or the dust collection space in

00118 this can be introduced. Such an adsorbent

00119 bag consists of a particularly air-permeable

00120 material such as a thin fleece

00121 paper or melt blown. In order to achieve a

00122 sufficient spatial distribution of the adsorbent in the

00123 dust collection space or in the suction filter bag

It is proposed that several smaller bags

00125 can be introduced with adsorbent, for example

00126 two bags with 5 grams of activated carbon each. In an alternate

00127 tive embodiment of the method is provided that

00128 the adsorbent in bulk in the dust collection space or

00129 dust filter bag is present. This turns out to be

00130 as advantageous that the adsorbent is intimate

00131 contact with the sucked dust, so that the

00132 odorants particularly easy to diffuse to adsorbent

00133 ren can. For example, the user can use

00134 a dosing container a predetermined amount of adsorbent

00135 through the filling opening of the dust filter bag or in

00136 bring the dust collection space. Alternatively, it can

00137 Adsorbent in the form of activated carbon also in portions

00138 bags are available. The user can therefore

00139 start of a first suction, i.e. after insertion

00140 zen of a new dust filter bag or after emptying 00141 of the dust collecting space a predefined portion of adsorber

Fill in 00142 bens. It is also alternatively provided that

00143 applied the adsorbent on the floor to be sucked

00144 is and together with the vacuumed up in the

00145 dust collection space or in the dust filter bag

00146 is brought. So the adsorbent is in the form of parti-

00147 none as bulk in an empty dust filter bag

00148 or dust collection space sucked in. Again, it's derik-

00149 bar that adsorbent by means of a metering container

00150 predefined output of an adsorbent portion on the

00151 sprinkle soil to be sucked. Another alternative is

00152 provided that the adsorbent in a storage container

00153 in the dust collection space or in the dust filter bag

00154 is available and in the course of vacuuming from the storage

00155 handle is sucked out. For example, in

00156 area of the suction air inlet opening of the dust filter

00157 beuteis or the dust collecting area an open edge

00158 bags or a cup-like container can be arranged,

00159 from which when the vacuum cleaner

00160 gers after a dust filter bag change or after

00161 an emptying of the dust collection space or in the course

00162 a closing of the dust collection space or the

00163 dust filter bag receiving filter chamber the adsor

00164 bens in the dust filter bag or the dust collection room

00165 is introduced. It is conceivable that by

00166 at least partial destruction of the storage bag or

00167 of the container the adsorbent for distribution in the

00168 Room emerges independently. Furthermore, there are solutions

00169 conceivable in which a container mt one through the

00170 suction air flow or through in the dust collection room

00171 or the dust filter bag prevailing negative pressure in

00172 a movable open position releasing the adsorbent

00173 cover is provided. 00174 00175 The invention also relates to a dust filter bag

00176 for a vacuum cleaner, in particular for use in

00177 a method according to one or more of the claims

00178 1 to 5, whereby here to reduce the initial odor

00179 surge when switching on the vacuum cleaner

00180 gene that an adsorbent in the dust filter bag

00181 loose form is present. As a result of this configuration

00182 the adsorbent is in intimate contact with the

00183 sucked in dust, so that the odorants especially

00184 can easily diffuse to the adsorbent. As a result of

00185 sen the odorants at the place of their origin

00186 bound. Here it proves to be particularly advantageous

00187 that such a diffusion odor filter inside

00188 half of the dust filter bag with a mediocre one

00189 adsorption kinetics does without the breakthrough

00190 an intense swell of smell when switching on the

00191 vacuum cleaner is carried out. As an adsorbent material,

00192 for example activated carbon, zeolites or porous

00193 polymers are used, these in broken / spherical form

00194 or as fibers. The size distribution, the chemical

00195 equipment (bactericidal and fungicidal substances) and

00196 amount of adsorbent is to the volume of the

00197 dust filter bag and to the area of application, i.e. on

00198 adapted the substances likely to be absorbed.

00199 Here, on the one hand, a possible

00200 provided efficient adsorption of the undesirable odor

00201 substances for which the ratio of macro, meso and

00202 micropores in the adsorbent is decisive. On the other hand

00203 are also application-related criteria.

00204 For example, the adsorbent of the

00205 dust filter bag the property itself evenly

To distribute 00206 in the bag and as permanent as possible

00207 on the inside of the bag wall. Diesbe-

00208 it can also be provided that these requirements

00209 met with a very fine-grained coal 00210 are. However, other materials are also used.

00211, such as molecular sieves in the form of a

00212 powders. The addition of a damp

00213 activity-binding agent (e.g. Selicagel) around the

00214 living conditions of microorganisms in the dust bag too

00215 deteriorate and at the same time the adsorption performance

00216 to increase the activated carbon. In the simplest case it is

00217 conceivable that adsorbent in the form of particles as rubble

00218 well before the start of a first suction process, i.e.

00219 after renewing the suction filter bag, on the

00220 and pour it into the empty dust filter

00221 suck in the bag. The adsorbent is here

00222 after in intimate contact with the sucked dust, so

00223 that the odorous substances are particularly easy to adsorb

00224 can diffuse. Alternatively, it can be provided

00225 that the adsorbent in an outside of the dust filter

00226 beuteis fastened storage container is arranged for

00227 emptied by hand into the dust filter bag. So will

00228 when inserting a new dust filter bag in the

00229 vacuum cleaner for example one with an adsorption

00230 material portion filled bag, which further example

00231 wise on the holding plate of the dust filter bag

00232 bar is fixed, removed and torn open around this

00233 contained adsorption material through the suction opening

Sprinkle 00234 into the dust filter bag. Such

00235 portioning bag can also be used in bulk to remove the dust filter

00236 bags can be assigned, which for the user

00237 possibility exists, the adsorption contained therein

Sprinkle 00238 material directly into the dust filter bag

00239 or spread on the floor to be vacuumed. Further

00240 alternatively it is proposed that the adsorbent in

00241 its own, air-permeable wrapping inside

00242 of the dust filter bag is included. The wrapping

00243 consists of an air-permeable material

00244 such as a thin fleece made of paper or 00245 Melt Blown. Such an adsorbent bag can already

00246 be factory installed in the dust filter bag.

00247 However, there is also the possibility of such

00248 Adsorbent bag loose or removable on the holding plate

00249 to assign the dust filter bag. The user brings

00250 this bag before putting the dust

00251 filter bag through the inlet opening into this,

00252 wherein the envelope of the adsorbent in its size to the

00253 Cross section of the inlet opening of the dust filter bag

00254 is adjusted. A surface area preferably has

00255 stretching the casing a fraction of a diam

00256 dimension of the inlet of the dust filter bag

00257 on. To further a sufficient spatial distribution of the

00258 to ensure adsorbent in the dust filter bag

00259 it is proposed that a plurality of adsorbent be

00260 parts are contained in the dust filter bag or in

00261 these can be introduced. It is also envisaged

00262 that in each case a plurality of adsorption particles in

00263 an envelope are included. So it is suggested

00264 that in a dust filter bag two bags with 5

00265 grams of activated carbon are introduced. In another

00266 alternative embodiment of the subject matter of the invention

00267 it is provided that a by air flow or Unter-

00268 printable adsorbent storage container on one

00269 inner wall of the dust filter bag is attached. So

00270 can, first of all through the filler opening of the

00271 dust filter bag extending storage container

00272 can be provided, which when switching on for the first time

00273 of the vacuum cleaner after changing the dust filter bag

00274 by the air flow or in the dust filter bag

00275 tel prevailing negative pressure from the inlet opening in

00276 the inside of the dust filter bag is torn. Here-

00277 at can be, for example, one with the adsorber

00278 act filled bag, which is initially in the

00279 area of the inlet opening is kept near the edge. By 00280 the air flow / vacuum is this off

00281 torn the inlet area, after which the content through

00282 provided openings of the container in the bag

00283 can escape. Alternatively, one such

00284 container can also be perforated, with the

00285 switching on the vacuum cleaner this along the perfora-

00286 tion tears off and releases the contained adsorbent.

00287 Alternatively, such a container can also be

00288-like, the inlet cross-section of the dust filter bag

00289 initially be designed to be closing. It is also

00290 also conceivable, a container on the underside of the holding plate

00291 to be placed near the edge of the filling opening. So can

00292 for example on the underside of the holding plate an annular

00293 total, container enclosing the filling opening

00294 can be seen, which is caused by the air flow or the

00295 suppress when switching on the vacuum cleaner

00296 Release of the adsorbent torn off the holding plate

00297 or in which by inserting the air flow

00298 or the negative pressure on the adsorbent in the container

00299 nis restrained lid or the like in a that

00300 adsorbent releasing position is shifted. About that

00301 there is also the possibility that the adsorbent in

00302 a storage container which can be revealed by puncturing,

00303 for example in a bag, overlapping to the

00304 suction port opening of the dust filter bag arranged

00305 is. According to the invention, a first

00306 me of the dust filter bag the user of this storage bag

00307 breakthrough, to distribute the containing

00308 Adsorbenses in the dust filter. This is preferred

00309 embodiment there application in which an air flow

00310 in terms of suction connected to a suction channel

00311 when closing the, hold the dust filter bag

00312 the filter chamber through the suction port opening of the dust

00313 filter bag holding plate occurs. Accordingly, the train

00314 this filter chamber closing process in the overlap 00315 to the suction port opening arranged adsorbent supply

00316 ratio pierced by the suction nozzle and thus

00317 opened, for releasing and distributing the adsorbent in

00318 the dust filter bag. Has proven particularly advantageous

00319 when choosing the adsorbent activated carbon powder

00320 a grain size fraction between 0.15 and 0.25 mm,

00321 where the undersize fraction is small with less than 2%

00322 is held. Activated carbon fibers are also very advantageous.

00323 sem with a diameter of 0.01 to 0.1 mm and

00324 a fiber length of 10 to 100 mm. Particularly effective

00325 full are also made from coconut shells

00326 carbon powder with CTC values greater than 60%. 00327

00328 The invention also relates to a dust collecting space for

00329 a vacuum cleaner, in particular for use in a

00330 Method according to one or more of claims 1 to

00331 5, here to reduce the initial smell surge

00332 is suggested when switching on the vacuum cleaner,

00333 that in the dust collecting space an adsorbent in bulk

00334 is present. Such vacuum cleaners are known

00335 whereby here the sucked up dust in the filterless

00336 system is deposited in the collection room. The stuffed

00337 te collecting space is for emptying the device housing

00338 removable. As a result of the configuration according to the invention

00339 the adsorbent is in intimate contact with the

00340 sucked in dust, so that the odorants especially

00341 can easily diffuse to the adsorbent. As a result of

00342 sen the odorants at the place of their origin

00343 bound. Here it proves to be particularly advantageous

00344 that such a diffusion odor filter inside

00345 half of the dust collection room with a mediocre

00346 adsorption kinetics does without the breakthrough

00347 an intense swell of smell when switching on the

00348 vacuum cleaner is done. As an adsorbent material,

00349 for example activated carbon, zeolites or porous 00350 polymers are used, these in broken / spherical form

00351 or as fibers. The size distribution, the chemical

00352 equipment (bactericidal and fungicidal substances) and

00353 amount of adsorbent is based on the volume of the

00354 dust collection room and to the application area, i.e. on

00355 adapted the substances likely to be absorbed.

00356 Here, on the one hand, a possible

00357 provided efficient adsorption of the undesirable odor

00358 substances for which the ratio of macro, meso and

00359 micropores in the adsorbent is decisive. On the other hand

00360 are also decisive for application technology.

00361 For example, the adsorbent of the

00362 ß dust collection the property itself evenly

00363 to distribute in the collection room and

00364 stick to the inside of the room wall. This-

00365 with regard to this, it can further be provided that these requirements

00366 changes from a very fine-grained coal

00367 are. However, other materials are also used.

00368, such as molecular sieves in the form of a

00369 powders. The addition of a damp

00370 activity-binding agent (e.g. Selicagel) around the

00371 Living conditions of microorganisms in the dust collection

00372 space to deteriorate and at the same time the adsorption

00373 to increase the performance of the activated carbon. In the simplest

00374 case, it is conceivable that adsorbent in the form of parti-

00375 none as bulk material before the start of an initial suction

00376 ganges, i.e. after emptying the dust collection area

00377 sprinkle the soil to be vacuumed and into the empty one

00378 Vacuum the dust collector. The adsorbent is located

00379 then in intimate contact with the sucked in

00380 dust, so that the smell is particularly easy to

00381 can diffuse adsorbent. Alternatively,

00382 hen be that the adsorbent in a storage container

00383 is arranged for manual emptying into the dust

00384 Melraum. This is what happens after the collection room is emptied 00385, for example, with an adsorbent material port

00386 on filled bag, torn open and the contained therein

00387 adsorption material strewn into the dust collecting space.

00388 With such a portioning bag, this can also be done

00389 adsorption material contained therein on the

00390 the floor to be distributed. Another alternative is

00391 suggest that the adsorbent in its own air-permeable

00392 casual wrapping within the dust collection area

00393 is included. The envelope consists of a

00394 breathable material such as one

00395 thin fleece made of paper or melt blown. The user

00396 brings this bag before the initial start-up of the

00397 dust collection in this one, the wrapping

00398 of the size of the adsorbent to the cross section of a

00399 inlet opening of the dust collection space is adjusted.

00400 preferably has a surface extension of the

00401 encasing a fraction of a diameter dimension

00402 of the inlet opening of the dust collection space. To continue

00403 a sufficient spatial distribution of the adsorbent in

00404 to ensure the dust collection room is suggested

00405 that a plurality of adsorption bags in the

00406 dust collection spaces are contained or incorporated in these

00407 can be brought. In addition, it is provided that

00408 a plurality of adsorption particles in an envelope

00409 lung are included. It is proposed that in

00410 a dust collection room two bags with 5 grams of active

00411 coal are introduced. In another alternative

00412 embodiment of the subject matter of the invention is provided

00413 hen that an openable by air flow or vacuum

00414 res adsorbent storage container on an inner wall

00415 of the dust collector is attached. Here it can

00416, for example, is one filled with the adsorbent

00417 act bag, which first, for example

00418 held the inside of the collecting space inner wall

00419 is. Due to the air flow / negative pressure 00420 this torn or torn, after which the content through

00421 provided openings of the container in the collection

00422 space can escape. Alternatively, such a

00423 ratio can also be perforated, with the

00424 switching on the vacuum cleaner this along the perfora-

00425 tion tears off and releases the adsorbent contained.

00426 Alternatively, such a container can also be

00427 be formed like. In addition, it is

00428 conceivable that the adsorbent in one by puncturing

00429 disclose storage container, for example in one

00430 bag is arranged. According to the invention, a

00431 initial start-up of the dust collection room of the

00432 who pierced this storage container for distribution

00433 of the containing adsorbent in the collecting space. On

00434 such puncturing can also automatically in the course of a

00435 collection chamber closing process take place, for example

00436 se through device-side, immersed in the collecting space

00437 device parts. It proves to be particularly advantageous with the

00438 Selection of the activated carbon powder adsorbent with a grain

00439 size fraction between 0.15 and 0.25 mm, the

00440 undersize is kept small with less than 2%.

00441 Activated carbon fibers with a

00442 diameter from 0.01 to 0.1 mm and a fiber length

00443 from 10 to 100 mm. Are also particularly effective

00444 Coconut shells made with activated carbon powder

00445 CTC values greater than 60%. 00446

00447 Finally, the invention relates to an air

00448 permeable wrapping, such as nonwoven

00449 containing adsorbent material, the wrapping in

00450 their size to the cross section of the inlet opening of the

00451 dust collection space or the dust filter bag adapted

00452 is. As a result of this configuration, one by one

00453 air-permeable covering enclosed adsorbent material

00454 rial through the inlet opening into the dust collection space 00455 or in the dust filter bag. Here-

00456 shows the main advantage that the adsorber

00457 bens in the immediate vicinity of the vacuumed up dust

00458 is positioned, thereby enriching a larger one

00459 amount of odor substances in the dust collecting space or

00460 dust filter bag is prevented because the forming

00461 Diffuse odors continuously to the adsorbent

00462 and be bound there. In this regard, will continue

00463 proposed that a surface extension of the envelope

00464 a fraction of a diameter dimension of the

00465 inlet opening of the dust collection space or the dust

00466 filter bag corresponds. For example, the

00467 surface area of the casing about a fifth to

00468 one tenth of the diameter dimension of the inlet opening

00469 match. For example, everyone can

00470 adsorbent bag with three to ten grams, preferred

00471 five grams of adsorbent material, such as

00472 activated carbon. 00473

00474 From the previously described inventive configurations

00475 for odor filtering or for the formation of a

00476 diffusion odor filters result in essential

00477 advantages. This is how the odor filters (the adsorbent

00478 in both bag and loose form) in the difference

00479 to a known standard adsorption filter not

00480 directly in the flow path. In addition, when using

00481 fertilizing the adsorbent in bulk on a support structure

00482 door are omitted, with different geometrical

00483 arrangements are conceivable. Furthermore, the pressure loss

00484 st which from a diffusion odor according to the invention

00485 filters are caused against the pressure drops,

00486 caused by a standard filter

00487 sigen. Furthermore, a diffuser according to the invention

00488 ons odor filter its effect even during breastfeeding

00489 Status of the device, so that in the dust filter bag or in 00490 the dust collecting space the emergence of a larger amount

00491 is prevented by odorous substances. The removal of the

00492 support structure is with a material saving and

00493 a significantly lower process engineering

00494 wall connected in the manufacture. In addition, the ad

00495 sorption performance by the user by adding an indi-

00496 individually selected amount of adsorbent to his needs

00497 adaptable (e.g. odor-intensive dust from pet

00498 attitude). Furthermore, it proves to be advantageous

00499 that the diffusion

00500 sions odor filter with every dust filter bag change

00501 or every time the dust collection

00502 ensures. As a result, after the change / emptying

00503 an odor filter with optimized adsorption characteristics

00504 stik before. A good level of efficiency is also

Given 00505 le with a diameter smaller than 0.5 mm. 00506

00572 is shown and described initially with reference to

00573 Fig. 1 is a vacuum cleaner 1 with a in a filter chamber

00574 mer 2 held dust filter bag 3. During the loading

00575 drive of the vacuum cleaner 1 is by means of a schematic

00576 table shown motor / blower unit 4 in the area

00577 a suction nozzle 5 on the foot side generates a negative pressure,

00578 by means of which dust and dirt particles from which to

00579 detergent floor 6 loosened and by means of the suction air

00580 mes via a suction channel, not shown, in the

00581 dust filter bag 3 can be transported. The engine /

00582 blower unit 4 is the dust

00583 downstream of filter bag 3. 00584

00585 The dust absorbed in the dust filter bag 3

00586 stays there for a certain time. During this

00587 Time is differentiated by the microbiological degradation

00588 whose dust constituents produce odorant, which

00589 before being adsorbed as detailed below. 00590

00591 For this purpose, an adsorbent 7 in the form of activated carbon,

00592 Zeolites or porous polymer in the dust filter bag 3

00593 entered or entered. 00594 00595 According to the exemplary embodiment in FIG. 1, this is the

00596 adsorbent 7 by means of a metering container 8 to

00597 absorbent base 6 is scattered and then

00598 would take the vacuum cleaner 1 together with the vacuum

00599 dust introduced into the dust filter bag 3. The Do-

00600 sier container 8 has the function of a sugar shaker

00601, which after a one-time tilting of the same

00602 predefined portion of the adsorbent 7 is output.

00603 The adsorption performance can, however, by the user

00604 by adding an individually selected amount of adsorbent

00605 bens 7 (by dispensing several portions of adsorbent)

00606 adjust the needs. For example, at

00607 odor-intensive dust from keeping pets

00608 double portion of adsorbent on the floor to be sucked 6

00609 are applied. 00610

00611 This adsorbent output or that preferably takes place

00612 suction and introduction of the adsorbent 7 in the dust

00613 filter bag 3 once at the first start-up

00614 of the vacuum cleaner 1 after changing the dust filter bag. 00615

00616 A vacuum cleaner 1 is shown schematically in FIG.

00617, which is for receiving the absorbed

00618 dirt / dust particles a separator and a

00619 after switched dust collection chamber 9. This

00620 vacuum cleaner 1 has no, replaceable if necessary

00621 dust filter bag according to the first embodiment

00622 on. Rather, the filled dust collecting space 9 becomes here

00623 emptied if necessary. 00624

00625 Also with this vacuum cleaner principle results from

00626 the whereabouts of the collected dust over a

00627 agreed period a microbiological degradation

00628 dust constituents, which reduces the production of

00629 has the desired odorants. In particular 00630 when switching on the vacuum cleaner 1 results from this

00631 an unpleasant initial smell surge, which

00632 in accordance with the inclusion of adsorbent 7 in the

00633 dust collecting space 9 is counteracted. 00634

According to the first described with reference to FIG. 1

00636 embodiment is also in this second embodiment

00637 example of the adsorbent 7 by means of a metering container

00638 sprinkled 8 on the floor 6 to be cleaned and

00639 then together with the vacuumed up dust in the

00640 dust collection room 9 spent. 00641

00642 By introducing the adsorbent 7 into the dust filter

00643 bag 3 or in the dust collection chamber 9 is located

00644 this in intimate contact with the sucked-in dust,

00645 so that the odorous substances are particularly easy to adsorb

00646 can diffuse. 00647

00648 A dust filter bag 3 is shown in FIG. 3,

00649 which before first use with adsorbent 7

00650 can be filled. This filling takes place here similarly

00651 borrowed the exemplary embodiments described above

00652 by means of a dosing container 8, for dispensing a

00653 predefined portion of adsorbent. The adsorbent 7 will

00654 directly into the filter bag 3 by sprinkling through the

00655 inlet opening 10 of the dust filter bag 3

00656 brings. The user also has the option here

00657 by adding an individually selected amount of adsorbent

00658 bens 7 the adsorption properties his needs

00659 to adapt. 00660

00661 In addition, the sprinkling of an adsorbent porous

00662 tion from the dosing container 8 also in the dust collection

00663 space of a vacuum cleaner 1 according to FIG. 2. 00664 00665 Further alternatively, the adsorbent 7 can also be available to the user in a pre-ported manner, for example 00667 in the form of an adsorbent portion containing 00668 the bag 11, which packs the dust filter bag 3 loose beige00669. According to the representations in FIGS. 4 and 00670 5, such a 00671 portion bag 11 forming a storage container 13 can also be associated with the dust filter bag 3, for example by a releasable arrangement of the bag 11 on the top of the dust filter bag retaining plate 12. The bag 11 is clearly arranged for 00675 the user on the holding plate 12, whereby 00676 the outline shape of the bag 11 according to the 00677 embodiment shown can be designed similar to an arrow. After removing the bag 11 from the holding plate 00679, the adsorbent 00680 contained in the bag 11 can be sprinkled through the inlet opening 10 into the dust filter bag 00681 3. For this purpose, the bag 11 can be torn along 00682 along a preferably perforated line. 00683 00684 Further alternatively, the adsorbent 7 can be available in a supply ratio 13. 00686 00687 In this respect, FIGS. 6 and 7 show an exemplary embodiment in which the storage container 13 is shaped like a bag with a peripheral edge 14 00690. A predetermined portion of the adsorbent 7 is contained in the pouch formed in this way. 00692 00693 The bag-like storage container 13 is positioned in overlap 00694 to the inlet opening 10 of the dust filter bag holder 00695 plate 12 and loosely inserted and held in the area of the surrounding 00696 edge 14 between two layers of the multi-layer holder plate 00697 te 12. The layers 00699 of the holding plate 12 which are otherwise bonded to one another in the usual manner in 00698 are in the region of the edge of the bag 00700 14 holding sections are not connected. 00701 In this regard, it is further conceivable to provide the annular zones of the two layers 00704 14 which fix the bag edge 00702 14 with a recess, for example embossing, for fixing the 00703 bag-like storage container 13. 00706 00707 After inserting the dust filter bag 3 into the 00708 vacuum cleaner 1 and then starting up 00709 of the device, the bag-like storage container 13 00710 is sucked out of the inlet opening 00712 into the dust filter bag 3 by the air flow or by the negative pressure built up in the dust filter bag 3 , The Adsor00713 bens 7 can then be distributed in the dust filter bag 3 00714, for which purpose the bag-like storage container 13 00715 is not closed over part of the circumferential edge 14. 00717 00718 As a result of this embodiment, the dust filter bag 3 is filled automatically with a predefined portion of adsorbent, which is then present in the dust filter bag 3 in a loose 00721 form. 00722 00723 FIGS. 8 and 9 show an alternative embodiment of a 00725 storage container 13 fastened on the underside of the holding plate 12. Here is shown a 00726 plan essentially rectangular storage container 00727 nis 13, which covers the inlet opening 10 00728 on the underside of the holding plate 12. The supply area 13 is in the area between the inlet opening 00730 10 and a narrow side edge of the holding plate 12 fully adhered to the underside of the latter. The free end of the supply container 13 facing away from 00732 of this adhesive point 15 has an opening 16 which, in the 00734 unused state of the dust filter bag 3 according to FIG. 00735 9 is closed by a plug-in flap 17 which is connected to the storage container 00736 nis 13 in the same material. 00737 00738 The storage container 13 containing a pre-defined portion of the adsorbent 7 is essentially self-sufficient so that, in the unused position according to FIG. 9, the storage container 13 extends almost 00742 parallel to the holding plate 12. 00743 00744 Due to the air flow that comes on when the vacuum cleaner 1 is started up or the negative pressure built up in the dust filter bag 2 00746, the storage container 13 is pivoted in the 00747 direction onto the inside of the dust filter bag, 00748 while simultaneously sucking out the insertion holes 17 to release the opening 16. The stored 00750 adsorbent 7 can then emerge and be distributed in the 00751 dust filter bag 3. 00752 00753 In this regard, it is further conceivable that the storage container lt00754 nis 13 is formed in the form of an open paper or film tube, which is folded over at the ends and 00756 underneath the inlet opening 10 of the holding plate 12 fi00757 (for example by inserting the free 00758 end in the entry opening 10). 00759 00760 Another alternative to the last described 00761 embodiment is shown in FIG. 10. 00762 Here a storage container 13 is shown in the form of a paper 00763 or film tube, the free, hinged end of which is fixed on the underside of the holding plate 12. In 00765 of the illustrated embodiment, this is realized by a wax adhesive that is easily detachable. By inserting 00767 of the suction air stream, the free end of the wax adhesive 00768 tears off to discharge the adsorbent 7. 00769 00770 Alternatively, according to FIG. 11, the storage container can be

00771 nis 13 may be provided with a perforation 19. This

00772 is on the underside in the form of a bag or a bag

00773 of the holding plate 12, covering the inlet opening 10

00774 all around, fixed on the edge of the support plate, for example

00775 se glued. The perforation line is preferred in

00776 Overlap to the edge of the entry opening. 00777

00778 When starting up the vacuum cleaner 1, this

00779 advice container 13 by the air flow or in the

00780 dust filter bag 3 pending vacuum along the

00781 perforation 19 completely or only partially torn off,

00782 according to which in the area of the perforation 19

00783 ends openings the stored adsorbent 7 freely in

00784 can escape the dust filter bag 3. 00785

00786 Generally applies to the versions in which the

00787 storage container 13 in the form of a bag or

00788 hose is formed that in the separated

00789 or opened storage container 13 stored adsorber

00790 bens 7 emerges entirely from the storage container 13,

00791 supports this by sucking them out of the

00792 Container in the dust filter bag 3. 00793

00794 For vacuum cleaners where the fluidic

00795 Connection between suction channel and dust filter bag 3

00796 through a through the inlet opening 10

00797 suction nozzle 20 is produced, the release of the

00798 adsorbent 7 stored in a storage container 13

00799 also by destroying the storage container 13

00800 means of the suction nozzle 20. 00801

Such solutions are exemplified in FIGS. 12 and

00803 13, with the holding

00804 plate 12, covering the inlet opening 10, a front 00805 advice container 13 according to the embodiment in Fig.

00806 11 is attached. The one when the one closes the

00807 dust filter bag 3 receiving filter chamber 2 through

00808 entering the opening 10 of the holding plate 12

00809 suction nozzle 20 tears along the storage container 13

00810 of the perforation 19, after which the container in the

00811 dust filter bag 3 falls. The stored adsorbent 7

00812 can thereafter from the destroyed storage container 13

Pour out 00813. Any residues in the storage container 13

00814 when starting up the vacuum cleaner 1 from the

00815 container sucked out into the dust filter bag 3. 00816

00817 in FIG. 13 is a cup-like storage container 13

00818, which has a peripheral edge 21

00819 is provided. The latter is held between two

00820 layers of the multi-layer holding plate 12. At least one

00821 position has a concentric to the inlet opening

00822 voltage 10 circumferential annular recess for receiving

00823 of edge 21. 00824

00825 The cup-like one lying in the inlet opening 10

00826 storage container 13 contains an adsorbent supply. 00827

00828 This storage container 13 essentially corresponds

00829 in plan the cross section of the inlet opening 10 and

00830 is made, for example, from a paper material

00831 represents. 00832

00833 When changing the filter bag and after that

00834 Closing the filter chamber 2 immerses the suction nozzle 20

00835 through the inlet opening 10 and thereby destroys it

00836 cup-like storage container 13 by this both

00837 in the area of the container cover 22 as well as in the area

00838 of the container bottom 23 pierces. Here too, 00839 after the stored adsorbent 7 freely in the dust

Exit 00840 bag 3. 00841

00842 Furthermore, an alternative embodiment is shown in FIG.

00843 device, in which the inlet opening near the edge

00844 voltage 10 on the underside of the holding plate 12 a cup-like

00845 storage container 13 is fixed, with a bottom 23,

00846 which when starting up the vacuum cleaner 1 by

00847 air flow or the built up negative pressure, for example

00848 se tearing along or tearing off, for

00849 Release of the adsorbent 7. 00850

00851 Due to the described arrangement of a storage container

00852 ses 13 in or below the holding plate, i.e. the

00853 facing inside the dust filter bag, the latter is automatically

00854 matically when using the loose for the first time

00855 adsorbent filled. The user also has more

00856 the possibility according to the first embodiments

00857 for example by means of a dosing container 8

00858 adapted to increase the dose of adsorbent. 00859

00860 The various filling options described

00861 development of the dust filter bag 3 can be found essentially

00862 also used in the dust collecting space 9 according to FIG. 2. The

00863 adsorbent 7 as bulk material has the particular advantage

00864 that this is in intimate contact with the sucked

00865 dust is located, so that the odorants especially

00866 can easily diffuse to the adsorbent 7. 00867

00868 Another possibility according to FIG. 15 is to

00869 the adsorbent 7 in its own, air-permeable

00870 wrapping 24 to be arranged. For example, here

00871 pastille-like bags with a plurality of adsorber

00872 particles can be provided. 00873 00874 The bags 25 thus filled with an adsorbent portion

00875 can already be installed in the dust filter bag 3

00876 can be arranged loosely. However, it is also conceivable that

00877 this bag 25 by the user before commissioning

00878 of the dust filter bag 3 or the dust collection space 9

00879 are thrown into this. For this purpose,

00880 that a surface extension a of the envelope 24 one

00881 fraction of the diameter dimension b of the inlet δff

00882 tion 10 or suction port opening of the dust filter bag

00883 3 or, in the case of a vacuum cleaner according to FIG.

00884 melraum 9 corresponds. For example, the area

00885 Chenextension a of the envelope 24 about a fifth

00886 up to a tenth of the diameter dimension of the

00887 step opening 10 correspond. 00888

00889 In order to ensure a sufficient spatial distribution of the

00890 lung 24 absorbed adsorbent 7 in the dust filter bag

00891 tel 3 or dust collection room 9 are to be ensured

00892 several small bags 25 provided with adsorbent 7. 00893

00894 Through the previously described embodiments of the

00895 object of the invention is the adsorbent 7 in the immediate

00896 spent close proximity of the vacuumed up dust. It

00897 will not only be during the flow

00898 of the operation of the vacuum cleaner for transporting adsorbent

00899 odors eliminated. The transport takes place

00900 especially in times when the device is silent

00901 takes place through diffusion of the odorous substances. The

00902 Enrichment of a large amount of odorous substances in the

00903 Dust filter bag 3 is prevented because the

00904 the fragrance continuously diffuses to the adsorbent 7

00905 dieren and be bound there. The diffusion thus formed

00906 sion odor filter comes with a mediocre ad

00907 sorption kinetics without the breakthrough of a 00908 intense swell of smell when switching on the device

00909 must be feared. 00910

00911 adsorbent 7, which is in bulk in the dust filter bag

00912 3 (see FIGS. 1 to 14) has the property

00913 manage to evenly in the dust filter bag 3

Distribute 00914, this if possible with permanent settling

00915 of the inner wall of the dust filter bag 3 or dust collector

00916 melraumes 9. The addition can also advantageously

00917 of a moisture-binding agent such as, for example

00918 silica gel can be provided to the living conditions of

00919 microorganisms in the dust filter bag 3 or in the dust collector

00920 melraum 9 deteriorate and at the same time the adsorption

00921 tion performance of the adsorbent 7 to increase. 00922

00923 All disclosed features are essential to the invention. In
