The dust binder particles are supplied for dust retention. An independent claim is included for a vacuum cleaner, particularly household vacuum cleaner.

Description

The Invention relates first a method for operating a vacuum cleaner, in particular household vacuum cleaner, with one, an air-permeable, saccular designed wall-mounted dust collector for filtering the dust-laden suction air.

method the type in question are known. Here are, for example air-permeable Vacuum cleaner bags for use, made of a special filter paper and / or various textile fabrics mostly multilayered are constructed. In this regard, It is also known, a prefilter for filtering Coarse dirt, a fine filter layer for filtering fine dirt and a support layer for protection and support to provide the fine filter layer. Next are also bagless systems in which the absorbed dirt due to weight - or centrifugal forces - in containers (cyclones, Water bath) is deposited and held.

in the With regard to the known prior art is a technical Problem of the invention seen therein, a method of in question standing style to improve so that thereby a dust pickup with elevated Dust removal is created.

These Problematic is first and substantially solved by the subject-matter of claim 1, wherein is pointed out that to form a filter layer in the Dust pickup at the beginning or before a first vacuuming of the wall, the consists of a paper or nonwoven layer and a total thickness of 1 mm or less, dust particles for dust retention be supplied. According to the proposed method, an improved dust-holding capacity is included otherwise usual Vacuum cleaner bags achieved. These consist in a known manner single or multi-ply paper or Fleece layers. The dust collecting space facing static filter layer become an increase the dust-holding capacity Supplied dust particles, which at least in the suction mode, on the inside of the wall at the paper or nonwoven layer stick. These dust particles are at least fed to the beginning of a first use of the dust absorption of the wall, continue optionally also at the beginning of each suction process. The adherents Dust-binding particles form one in the air flow direction of the paper or nonwoven layer upstream, self-acting constituting separator, the total of a filter bag inside Position forming dust particle with regard to particle retention and degree of separation are designed so that fine dust particles reliably deposited which clogs the paperwork behind it. or nonwoven layers is avoided by fine dust. Accordingly requires it in the preparation of such with additional Staubbindeteilchen provided bag not provided on the bag side fine dust filter layer, which continues in the cheapest Case a single-layer design of the dust receptacle is sufficient. This especially proves to be low in production. The dust particles are already in one embodiment production side spent in the dust receptacle, this further preferred in free-flowing Shape. Only with first use of the dust pickup and associated Saugstromdurchsetzung be loosely introduced Staubbindeteilchen arrested for forming the inner fine dust layer on the paper or nonwoven layer. Alternatively, a separate one is also before the beginning of a suction process feed the dust particles in the dust receptacle possible.

The The invention further relates to a method according to the features of the preamble of claim 1.

at the well-known air-permeable Dust filter bags builds in the course of use in particular a dust cake on the vertical walls of the inner layers. This leads in usually to an increasing pressure loss, which with a decreasing Suction power is connected. The more layers of different materials provided on the bag side, the thicker and less flexible the filter bag, which is especially true when handling the insertion of the filter bag proves to be disadvantageous. Dust filter bags are depending on filling level and / or depending replaced by an optionally detected pressure loss threshold.

at Bagless systems in which the absorbed dirt in one container is deposited, the user comes with the emptying of the container in contact with the dirt. About that In addition, the container must and optionally downstream filter changed at regular intervals or washed out.

in the With regard to the prior art described above, a Technical problem of the invention seen in it, a method the type in question while minimizing pressure losses and considering to improve hygienic and easy handling.

This problem is first and foremost solved by the subject matter of claim 2, wherein it is based on the fact that the air-permeable wall for multiple use remains in the dust receptacle and that to form a filter layer in the dust receptacle at the beginning or before ei In the first vacuuming of the wall dust particle particles for dust retention are supplied. The existing in the vacuum cleaner and always remaining air-permeable wall forms a support structure, with the help of which a filter is constructed for filtering the dust-laden suction air. This is due to the attachment of dust-binding particles which form the filter medium adhering to the supporting layer (air-permeable wall). This Staubbindeteilchen be supplied to the beginning of commissioning of the vacuum cleaner, that is, at the beginning of the vacuum cleaner or before a first vacuuming the air-permeable wall. This is done, for example, manually by the user, but preferably automatically in response to a startup of the vacuum cleaner. In a preferred embodiment, the dust particles remain after a first adhesion to the permeable wall at this, this also after completion of the suction, that is, after switching off the vacuum cleaner. There is such a method by which an automatically self-building separator is achieved. The soaked dirt particles arrest at the dust cake particles forming a filter cake, this with a particle retention or with a degree of separation, which is comparable to the usual filter bag.

In a development of the subject invention according to claim 2 is provided that in case of feeding before a first vacuum the Staubbindeteilchen with auffächerbarer Mobility are tied to the wall. These dust particles are inside the air-permeable Wall arranged so that these in operation, ie at Vacuuming, forming a filter layer on the air-permeable wall and thus the dust retention, especially particulate matter retention serve. Furthermore, in this case the dust binder particles in number and design designed so that during the vacuuming a preferably homogeneous, in particular full-surface filter layer results. Arrest the dust particles especially during operation which are introduced into the dust receptacle by sucking or blowing Dirt particles. About that Hi-naus is preferred that these dirt particles at least partially even after a first vacuuming and waste of the suction flow continue to arrest the dust particles. By the proposed auffächerbare Mobility of dust particles when connected to the Wan dung results from flow reversal a advantageous disposal of adhering to the dust particles Dirt and dust particles. So is preferred by a disposal Blowing provided, wherein the flow through the wall of the Dust pickup is directed inward, according to this flow itself the dust binding particles attached to the wall into the dust receiving space auffächernd Set up and the dust or dirt held to blow out release from the dust receptacle.

9 another one 6 corresponding sectional view relating to a third embodiment.

Shown and described is first with reference to 1 a vacuum cleaner 1 , in particular household vacuum cleaner, which is designed as a hand-held handle unit. This first has a base unit 2 on, with an unillustrated electric motor for a suction / blower unit 3 , On the base unit 2 is a designated for receiving the sucked up dusty dust receptacle 4 supported.

The power supply in the base unit 2 integrated electric motor via an electric cable 5 ,

Next has the base unit 2 a gooseneck-shaped extension which extends over the area of the dust receptacle 4 extends. In the area of the free end, this plug-in attachment forms a plug-in receptacle for a handle 6 of the vacuum cleaner 1 out. In the area of the free end of the stalk 6 is an operating handle 7 intended. This has a thumb-actuated actuator in the form of a slide switch, via which the power of the base unit 2 recorded electric motor or the suction / blower unit 3 is adjustable.

For soil cultivation is the basic device 2 fluidly with a header 9 connected. This may be a suction nozzle having a rotating brush.

The suction mouth, not shown, of the attachment 9 is fluidly connected to the dust collector 4 What a flow channel 10 the basic device 2 interspersed.

The dust pickup 4 in the 1 to 6 shown first embodiment initially has a plate-shaped, closed bottom 11 on. This is with a flow opening 12 provided, the underside of the soil 11 is connected to the flow channel 10 ,

Opposite to the flow channel mouth carries the ground 11 a gridded basket 13 , According to its basket-like design, this has over its entire surface an air-permeable wall 14 on.

According to the prescribed arrangement, the basket is 13 in overhead position in the dust receptacle 4 held under support by means of the soil 11 on a housing cover 15 of the base unit 2 ,

The basket 13 is further overlapped by a, an air-impermeable wall having housing portion 16 , The inner wall of the housing section 16 is spaced from the outer wall of the basket 13 , according to which between basket 13 and housing section 16 a flow clearance 17 remains.

This flow free space 17 is to the Umge closed exercise. The the basket 13 or its bottom 11 supporting housing cover 15 of the base unit 2 at the same time forms the sealing end of the housing section 16 to the base unit 2 out. The housing cover 15 is only in the flow-through 12 of the soil 11 remote area of the flow clearance 17 breached. Here is the flow free space 17 into a canal section 18 of the base unit 2 , This is connected to the suction / blower unit 3 , continue with the usual suction operation of the vacuum cleaner 1 adjusting suction side. The usual operation of the vacuum cleaner 1 self-adjusting pressure side of the suction / blower unit 3 opens by means of another channel section 19 towards the surroundings.

The flow opening 12 in the ground 11 is to prevent trickling of in the basket 13 collected dirt particles by a pivoting on the ground 11 arranged flap 20 closable. This opens to Korbinnern towards a Saugluftbeaufschlagung, especially in the usual suction against a spring acting in the closing direction.

In the usual suction mode as shown in 4 is via the suction / blower unit 3 generates an air flow, wherein the particle-laden suction air via the flow channel 10 , the flow opening 12 of the soil 11 interspersing in the basket 13 whose wall 14 is sucked through. The in the dust pickup 4 filtered air then passes over the flow clearance 17 and the channel section 18 to the suction / blower unit 3 ,

For filtering the suction air is the basket 13 Inside wall with a layer of Staubbindeteilchen 21 Mistake. In a preferred embodiment, these are fibers which are located on the inside of the air-permeable wall 14 adhere. Only these adhesive dust particles 21 form the filter F of dust pickup 4 , The dust particles 21 cover the air passage openings 22 the wall 14 to the extent that dust and dirt particles, with the suction air in the basket 13 are registered at the layer of Staubbindeteilchen 21 attach (cf. 5 and 6 ).

The so in the course of a suction operation building up filter cake from Staubbindeteilchen 21 and adhering dirt and dust particles 23 will be disposed of together if necessary. This also means that the filter-giving layer of dust particles 21 Will get removed. Only the shape and stability giving basket 13 with its air-permeable wall 14 remains for multiple use in the dust receptacle 4 ,

The disposal of the filter cake is achieved in the illustrated embodiment by arranging the vacuum cleaner 1 to a supply / disposal station 24 , This is a stationary element, which in the illustrated embodiment, a footprint 25 for the vacuum cleaner 1 and the back of the upright vacuum cleaner 1 in a housing 26 recorded containers 27 and 28 having.

The container 27 serves to accommodate the discarded Staubbindeteilchen 21 and dirt-dust particles 23 , The container volume is several times greater than the volume of the vacuum cleaner side basket 13 ,

In assignment according to the 1 to 3 is the vacuum cleaner 1 over two separate airways 29 and 30 with the containers 27 and 28 in connection. An airway 29 flows directly above the ground 11 in a side wall of the basket 13 , The purpose and with the airway 29 related suction opening 31 in the wall 14 is by a pivotable, resiliently loaded in the closed position flap 32 locked. The loaded closing direction acts in the direction of the basket interior.

The one in the basket 13 with usual suction work of the vacuum cleaner 1 prevailing negative pressure supports the flap closure position in an advantageous manner.

For disposal is the vacuum cleaner 1 to the station 24 docked so that the airway 29 fluidly connected to the container 27 the station 24 ,

About the actuator 8th , if necessary via a separate switch, the suction / blower unit 3 activated in the blowing mode, so that over the channel section open to the environment 19 Air is sucked in, which over the further channel section 18 and the flow clearance 17 from the outside through the passages 22 into the basket 13 penetrates, wherein the wall inside filter cake built up from the wall 14 detach under Luftdruckbeaufschlagung and continue on the air flow in the station-side container 27 is discharged. The air flow causes the flap to open 32 against the spring effect. The flap 20 the flow channel side flow opening 12 is effectively pressurized loaded in its closed position.

Following this procedure is the dust pickup 4 blown out, after which only the basket 13 in the dust receptacle 4 remains.

After completion of the emptying process and corresponding shutdown of the suction / blower unit 3 it shuts 32 back to her Ver conclusion, after which further preferably automatically re-supplying the dust 4 with dust particles 21 to prepare the vacuum cleaner 1 and to form the filter F begins.

This is the further airway 30 used. This opens laterally into the flow channel 10 within the base unit 2 , where the set here de opening 33 to the flow channel 10 in the usual suction operation of the vacuum cleaner 1 through a butterfly valve 34 closed is. This is in the area of the opening 33 pivotally supported and acted upon under spring load in its closed position.

The airway 30 is in assignment position of the vacuum cleaner 1 to the station 24 in connection with the container 28 , which is a reservoir of dust particles 21 forms.

After opening the butterfly valve 34 , which for example via an activated actuator of the station 24 can be achieved, sets the suction / blower unit 3 in the usual way, namely in the suction mode. Correspondingly, over the remaining portion of the flow channel 10 and the airway 30 Staubbindeteilchen 21 from the container 28 sucked, after passing through the bottom-side flow opening 12 into the basket 13 occur and as a result of the suction through the air-permeable wall 14 adhere to the inside of the wall to form a new, non-contaminated filter layer. To obtain a sufficient filter layer is a predetermined amount of dust binder particles 21 into the basket 13 to suck. This can be controlled on the station side by means of a particle penetration in the airway 30 measuring monitoring unit. Alternatively, dust particles can always be present for a predetermined period of time 21 be sucked, which period is designed so that in principle a sufficient filter layer is constructed.

In the figures, the arrangement of Staubbindeteilchen 21 shown spaced apart for clarity. In operation, the dust particles are 21 so overlapping and close to each other, that sets a closed filter layer that reliably separates even fine dust.

By the proposed solution is a filter change allows without the user having the contaminated filter material and / or in contact with dirt particles.

The collection container 27 is for final disposal of the collected filter cake particles from the station 24 removable. The container 28 is accessible for refilling or refilling with new dust particles 21 , The size of this container 28 is preferably chosen so that multiple feeds of new dust particles 21 in the dust receptacle 4 without refilling the container 28 can be performed.

The disposal and supply of the vacuum cleaner 1 may depend on a measured pressure loss in the flow clearance 17 done in the usual suction. Due to the selected arrangement, it is also possible, the vacuum cleaner 1 For example, daily to empty automatically and with a new, through the Staubbindeteilchen 21 equipped filter F to equip.

The 7 and 8th show a second embodiment, wherein in accordance with the previously described first embodiment, basket-like design of the dust receptacle 4 the dust particles 21 in the form of fibers in the region of one of its ends inside the wall of the basket of dust pickup 4 are connected. This connection can be made by gluing or, for example, in the case of a plastic basket as a dust receptacle 4 be achieved by welding, in addition also electrostatically. The dust particles 21 are due to the captive on the dust container 4 tied, while maintaining a auffächerbaren mobility of Staubbindeteilchen 21 ,

In the usual suction according to 7 put the dust particles 21 inside the wall at the dust receptacle 4 or on the grid basket 13 in such a way that the air passage openings 22 Covered like a filter layer. The dust and dirt particles entrained with the air flow arrest the dust particle 21 and are thus deposited.

In the case of flow reversal as shown in FIG 8th put the tailed Staubbindeteilchen 21 in the direction of the dust-collecting interior fanning out, this possibly with fluttering movement of the fibrous dust-binding particles 21 , which leads to the release of the trapped dust or dirt, which is entrained with the air flow for disposal.

9 shows an embodiment with a Staubaufnahmewandung 14 which consists of a paper layer. This has a thickness of 1 mm or less. On the inside of the wall, facing the dust-collecting space, the here also fibrous dust-binding particles are laid 21 to form a fine dust filter layer. As a result, the dust-holding capacity of a filter bag designed in this way is increased, in particular in the case of a simple, that is to say one or two-layer design of the wall 14 ,
