Definitions

  • the invention relates to a vacuum cleaner for sucking and accumulating particles in at least one collecting chamber, comprising at least one receiving chamber for suction means comprising a motor driven fan, wherein the collecting chamber and the receiving chamber are separated by a partition wall having an inlet opening for an air flow of the collecting chamber to the suction means, and wherein the partition wall as an inlet opening for coupling the collecting chamber to the suction means of the receiving chamber has a tapered from its inlet surface at the collecting chamber in the direction of the suction air duct funnel whose entrance surface forms the essential part of the partition wall surface.
  • the invention has for its object to provide a vacuum cleaner, the suction power is improved even with a compact design and at the same time avoids the risk of injury by rotating fan blades.
  • the air duct funnel in its funnel base has an engagement protection element, which is formed by a dome-like or otherwise shaped rib body in the direction of the collection chamber, the gaps for largely unimpeded passage of the air flow from the Having collection chamber to the suction means and cut off the protective ribs in the middle of the hopper of the Lucasleittrichters, that is to the opening to the fan, in the direction of the collecting chamber.
  • the dividing wall has as an inlet opening an air-conducting funnel whose inlet surface forms the essential part of the dividing wall surface, an excessive pressure loss of the airflow from the collecting space or the collecting chamber to the suction means is largely avoided. Furthermore, this overly affecting noise development is largely avoided. Because the larger the entry surface of the air guide funnel is selected, the less resistance is opposed to the directed to the suction air flow. Thereby are much less
  • Air turbulence in the direction of the collection room possible. Overall, a directional air flow from the collecting space through the air guide funnel to the suction means can be improved.
  • FIGS. 1 5 each provided with the same reference numerals.
  • FIG. 1 shows schematically in plan view the arrangement of the essential components of a vacuum cleaner SS, which is formed according to the principle of the invention. It has at one end face of its housing GH an inlet opening EO with preferably circular cross-section for sucking suction air SL.
  • a first collecting chamber or a collecting space SR is provided, which serves to accumulate particles or particles to be sucked, in particular dirt particles or dust particles.
  • a filter bag or dust bag PF for receiving the sucked from the outside through the inlet opening EO into the collection chamber SR dirt or dust particles ST is used.
  • the filter bag PF is at the output side end of the approximately tubular inlet opening EO inside plugged so that outside sucked particles or particles directly into the interior of the dust bag PF.
  • a vacuum cleaner tube or a vacuum cleaner hose is usually coupled to the inlet opening EO, with which dust particles can then be absorbed by a carpet, for example.
  • At least one filter element for example a filter fleece, in the collecting chamber SR between the inlet opening EO and the dust bag PF.
  • the housing GH of the vacuum cleaner SS of Figure 1 is separated from the collecting space or from the collection or dust chamber SR a receiving chamber MR through an intermediate wall TW.
  • This receiving space MR serves, in particular, for accommodating and storing suction means with which a directable suction air flow LF can be produced through the inlet opening EO, the collecting space SR and the dust bag PF optionally provided there.
  • the routing of the air flow LF through the interior of the housing of the vacuum cleaner SS is indicated by dashed arrows.
  • the suction means are formed at the vacuum cleaner SS primarily by a blower GB known type, which is driven by a motor MO.
  • the rotor blades of the blower GB are designed so that they suck air from the outside through the inlet opening EO in the interior of the housing GH, let flow through the collecting space SR, then sucked through an inlet opening in the dividing wall TW in the receiving space MR, and finally by Outlet openings AO in the housing GH blow out to the outside again.
  • the outflowing air is in the FIG. 1 also indicated by dashed arrows AL.
  • MR may also be accommodated in the receiving space MR optionally other components of the vacuum cleaner such as its cable drum KT for winding an electrical connection cable KA.
  • the inlet opening in the partition TW is expediently provided at such a point that the air flow LF from the inlet opening EO through the collecting space SR to the suction means GB, MO behind the Dividing wall TW in the receiving space MR is directed substantially rectilinear guided.
  • the inlet opening in the dividing wall TW is designed as an air-guiding funnel LT. This air-guiding funnel LT tapers, starting from its entry surface, to the collecting space SR in the direction of the suction means GB, MR. At its outlet opening directly the suction means, in particular the fan GB as close as possible mechanically coupled.
  • FIG. 2 An expedient embodiment of the Lucasleittrichters LT of FIG. 1 shows FIG. 2 in spatial representation in detail.
  • the Luftleittrichter LT has a substantially rectangular entrance surface RE for the air flow LF from the dust chamber SR.
  • the entry surface RE of the Lucasleittrichters LT includes substantially flush with the otherwise preferably plan trained partition TW from.
  • the inner walls of the Lucasleittrichters LT then run starting from this rectangular outer contour to each other in the manner of a cone in the direction of the suction means, which sit behind the partition wall TW yes.
  • the inner walls of the Heilleittrichters LT finally form a cross-sectionally approximately circular outlet opening for the positive connection of the approximately circular discharge pipe of the blower GB.
  • FIG. 4 This form of the Lucasleittrichters LT as Ankoppelkomponente for the air flow LF between the collection chamber SR and the receiving chamber MR is in the FIG. 4 enlarged by a cross-sectional image shown in side view.
  • the interior of the shipsleittrichters LT ends with an approximately circular outlet opening KRO.
  • the blower GB is mechanically coupled.
  • the wheels LR of the blower GB are the front side guided in the sealing element GT, where they grind largely dense due to the operation.
  • a buffer is present through the sealing element GT the respective impeller such as LR and the outer casing of the blower GB formed.
  • the Luftleittrichter LT is now advantageously formed as an inlet opening in the partition wall TW such that its entrance surface forms the essential part of the partition wall surface.
  • the entry surface RE of the air guide funnel LT occupies at least 50%, preferably between 70 and 80%, of the total area of the dividing wall TW.
  • the air-conducting funnel by virtue of its shape tapering in the direction of the suction means GB, MR, brings about a homogeneous transition for the airflow LF from the collecting chamber SR to the suction means coupled to the outlet opening of the air-guiding funnel LT.
  • MR preferably has a circular cross-section, which is substantially smaller than the cross-sectional width of the partition wall TW.
  • an additional effect for the air flow LF from the collecting chamber SR through the dividing wall TW into the receiving space MR is effected.
  • the air flow LF can be directed by the receiving chamber SR and the dust bag PF introduced there in a targeted manner, i. provide a routing for the air flow.
  • the air flow LF is guided by a corresponding alignment of the inlet opening of the Lichtleittrichters LT on the opposite inlet opening EO of the collecting chamber SR substantially straight.
  • the sucked air flow LF is opposed to a lower air resistance, as if the inlet opening in the partition wall TW would be formed only circular.
  • the air guide funnels back into the collecting space SR The larger the inlet funnel of the air guide funnel LT is selected, the less undesired reflections of the air flow LF back into the dust space SR and the better the air flow through the blower GB of the suction means can be sucked out of the dust space SR.
  • a projecting in the direction of the collecting chamber SR engagement protection element ES provided.
  • This is preferably formed curved conical.
  • it has a rib body with gaps for passing the air flow LF.
  • This fin body is oriented in opposite directions to the taper of the inlet channel of the Lucasleittrichters LT.
  • it also has a funnel shape that widens in the direction of the collection chamber SR.
  • the operator is prevented from entering the fan unacceptably into the fan, so that, for example, hand injuries caused by the rotating fan blades are largely avoided.
  • the free air cross section between the individual ribs can advantageously be made as large as possible, and thus a relatively small obstruction of the air flow can be achieved despite this additional protective measure.
  • the dome-like engagement protection element ES in the direction of the collecting chamber SR only light so far that its outer contour is flush with the entry surface of the RE Lucasleittrichters LT.
  • at least one filter element FI can be mounted in front of the inlet opening of the air guide funnel LT by means of two web clamps SI1, SI2 arranged laterally from the entry face RE of the air guide funnel LT.
  • This filter element FI is used for further purification of the exhaust air LF, which is withdrawn from the dust chamber SR. It may be designed in particular as a pollen or allergic filter.
  • One or more filter webs FIV are preferably clamped between the two halves of a booklet-like holding grid HF. This is in the FIG. 5 represented where the other components of the vacuum cleaner are shown in disassembled state.
  • the partition wall TW, the Luftleittrichter LT and its superior engagement protection element are formed as a one-piece component. It is not part of the invention to manufacture these three components as individual components and then to mechanically couple them to one another.
  • the spoiler funnel that is, be integrated directly into the plastic housing of the partition wall between the dust chamber and engine compartment.
  • On the engine compartment side of the engine or the associated fan is then suitably coupled via rubber parts to the outlet opening of the Heilleittrichters and sealed.
  • the Luftleittrichter can optionally be plugged as an additional part on the engine or the Gebläsehaube.
  • the whole unit is then coupled via rubber parts of known type in the device body and sealed.
  • the suction could only reach very strong curvatures from the dust chamber in the fan.
  • This spoiler funnel is advantageously designed in the dust chamber to increase the entrance surface as a rectangle.
  • the funnel shape preferably runs swiftly and without a contour jump towards the round diameter of the blower inlet opening.
  • protective ribs may be installed in the funnel center (opening to the fan).
  • the ribbed body is expediently designed to be funnel-shaped in the opposite direction to the air-conducting funnel outward in the direction of the dust space. Due to this special funnel shape of the motor protection grid (ribbed body), the free air cross section between the individual ribs can be made as large as possible or a relatively smaller obstruction of the air flow can be achieved. As a result, an overall increase in air capacity and thus an increase in the output of the respective vacuum cleaner is possible.
