Definitions

  • the invention relates to a device with blow-out filter, such as movable floor device, especially vacuum cleaner, with one at least along a portion of Side walls of the device in the circumferential direction as the above Partially extending bandage consisting of a Carrier consists of an elastic material is formed.
  • the object of the present invention is based on from GB-A-2 117 229 a device of the aforementioned type Art to construct such that both a minor Flow resistance as well as adequate Soundproofing is achieved.
  • the support body in the region of its side facing away from the side wall Expansion with an air permeable cover is made of a flexible material, being in the region of an extension facing away from the cover of the supporting body, a connection for blow-out Air is arranged and the support body with the connection the cover connects via at least one flow path.
  • the low flow rate in the filter area also has the advantage that a high degree of separation of suspended matter is reached. By the Relatively large filter volumes will still be very high Guaranteed filter life.
  • the support body of the Bandage consists of an elastically compressible material.
  • the support body By forming the support body from an elastic or elastically compressible material Provide bandage with a very flexible consistency, which even when in contact with sensitive Materials ensures that the bandage gives way and damage to equipment and the device is avoided.
  • the cover of the support body with the flexible material prevents damage of the supporting body, in addition, becomes a large one Design leeway provided for the surface design.
  • This scope can be used on the one hand be the physical properties of the cover suitable to choose and for example a very to provide soft surface, in addition there is also considerable scope for design the color and decorative training.
  • a particularly soft surface in the area of the cover is provided by the cover is formed from a textile material.
  • a high resilience in the area of the supporting body is created in that the support body Foam is formed.
  • Holding the protective bandage is guaranteed that in the area of the side walls in the circumferential direction extending projections are arranged in the run essentially parallel to each other and grooves train in the cover with its edge areas fixable insertable.
  • the cover is clamped in a simple manner suggested that the projections fit into one Extend interior of the housing facing away.
  • the protrusions extend towards the Extend interior of the housing.
  • a production of the stiffening element and the connection of the stiffening element with the cover in One operation is supported in that the Stiffening elements at least in some areas Plastic and / or cardboard are formed.
  • a large-scale discharge of the exhaust air is also thereby supports that in the area facing one of the cover Surface of the support body flow grooves for Air duct are arranged.
  • the design freedom in the constructive design the cover can be supported that the cover is formed from at least two layers is.
  • At least one of the layers be considered a Microfilter is formed.
  • FIG. 1 shows a vacuum cleaner (1), consisting of a housing (2) with an upper part (3) and a lower part (4) in the area of a bandage (5) are interconnected. At the bottom (6) the vacuum cleaner (1) rollers (7) are arranged. Further a suction hose (8) is provided and an electrical one Connection is via a cable (9).
  • the protective bandage (5) in the area between the upper part (3) and lower part (4) of the Housing (2) arranged.
  • the top (3) and that The lower part (4) forms a in the area of the bandage (5)
  • Side wall (10) In the area of an outside (11) the side wall (10) which an interior (12) of the Vacuum cleaner (1) is arranged facing, extends itself both in the area of the upper part (3) and Area of the lower part (4) an angular projection (13).
  • the projection (13) consists essentially from a cross leg connected to the side wall (10) (14) extending perpendicularly from the side wall (10) rises and out of a bracket leg (15) starting from the cross leg (14) parallel extends to the side wall (10). Between the bracket leg (15) and the side wall (10) is a groove (16) arranged.
  • the protective bandage (5) consists of a supporting body (17) made of an elastically compressible material is formed.
  • a material for the support body (17) for example foam rubber used.
  • Alternative is the use of an elastic material for the Support body (17) provided as a molded soft rubber.
  • stiffening elements (20) on have a substantially plate-shaped design and are made of cardboard or plastic. The Stiffening elements (20) can be inserted into the groove (16) and thereby stretch the cover (18) over the Support body (17).
  • the cover (18) is permeable to air executed.
  • the support body (17) is in the range of Side wall (10) for receiving the support body (17) Well (21) formed. This will make the available Elasticity of the support body (17) increased. Outgoing extends from the recess (21) with a center line (22) the support body (17) over the bracket leg (15) out. In particular, it is thought the bracket legs (15) in the area of the groove (16) facing away also with the support body (17) cover.
  • the support body (17) has hereby an approximately T-shaped contour, whereby the main leg of the T-contour is relatively wide is.
  • a supply element (25) which has an exhaust air duct (26) limited in the area of the interior (12) facing the back of the support body (17) is.
  • the device is to be blown out through the exhaust air duct (26) Exhaust air in the area of the supporting body (17) headed.
  • the feed element (25) can be tubular be and in a relatively limited space Exhaust air area in the area of the supporting body (17) lead, but it is also possible to make one in the circumferential direction elongated design of the feed element (25) to choose a large inflow area for the To provide support body (17). Beyond that it is conceivable in the circumferential direction within the interior (12) arranged distribution element, for example a ring line to be arranged over a plurality of feed elements (25) with the back of the support body (17) is connected.
  • the cover becomes stretched (18) relieved, moreover rises the support body (17) in the region of a center line (22) farthest over the side wall (10), which is the compliance upon contact with a piece of furniture elevated.
  • the stiffening element (20) is, for example, by Sewing or gluing connected to the cover (18). In principle, it is also conceivable that Stiffening element (20) as an envelope of the cover (18) to train.
  • the recess (21) and the Projections (13) preferably run around the entire Canister vacuum cleaner (1) around.
  • the projections (13) run parallel to each other and to the deepening (21). To enable easy manufacture the projections (13) together with the upper part (3) and the lower part (4) made as an injection molded part.
  • the supporting body (17) is preferred in this embodiment designed in such a way that in the area of the groove (16) an elastically deformable extension (24) is provided is. As a result, the support body (17) braces in Area of the groove (17) and fixes the cover (18) by. Because of the stiffening element (20) is thus also in this embodiment sufficiently strong anchorage of the cover (18) guaranteed.
  • Fig. 4 shows a surface facing away from the interior (12) of the support body (17) installed in a Condition the cover (18) is wearing.
  • an air duct (27) which in Area of its expansion facing the interior in the exhaust air duct (26) opens.
  • flow grooves (28) arranged that an air distribution below the cover (16) support.
  • Circumferential grooves (29) of greater depth and in the circumferential grooves (29) opening transverse grooves (30) less Depth to use Basically it is also conceivable, instead of the flow grooves (28) complementary Trained flow bars to use the cover (18) at a distance from the other surface of the supporting body (17). This also makes one Air expansion supported below the cover (18).
  • FIG. 5 shows a further embodiment.
  • a distribution trough (31) open into the bypass grooves (32) that start out from a lateral area of the supporting body (17) to the area of the cover (18) extendable surface of the support body (17).
  • the support body is formed (17) made of foam or comparable materials are flow grooves (28) and bypass grooves (32) usually unnecessary.
  • a further support of the filter properties can through a multi-layer design of the cover (18) are caused.
  • the different variants for filtering each represent the function of a blow-out filter ready.
