Definitions

  • the present invention relates to a vacuum cleaner having a centrifugal separator having an air inlet passage connected to a suction air guide for dust-laden suction air and having a separation space and an air outlet, the air inlet passage opening into the separation space.
  • Such vacuum cleaners are known from the prior art.
  • Components of such a vacuum cleaner are essentially one or more nozzles for receiving the dust, a suction pipe, which is designed depending on the structure of the vacuum cleaner as a floor, hand or upright vacuum cleaner shorter or longer or rigid or telescopic, a connector which the suction pipe with a flexible suction hose connects, one or more dust container, which may be part of the centrifugal or the separator or is designed as a separate dust collector, a vacuum chamber through which the air is sucked by a motor-fan unit, and optionally a fine dust filter for Final cleaning of the escaping air.
  • the EP 1 681 099 A2 discloses a cyclone Staubabscheide observed with a cyclone chamber, a surrounding the outer periphery Schmutzsammeihunt and a top lid.
  • the cyclone chamber opens an inlet pipe, from which the dust-laden air is sucked in and is guided by a spirally rising guide to the lid.
  • the lid forms a connection of the cyclone chamber with the dirt collecting chamber, wherein on an inner wall of the lid, a projection for preventing backflow of dirt accumulated in the dirt collecting chamber is arranged in a rollover of the vacuum cleaner.
  • the invention has for its object to provide an improved centrifugal separator for a vacuum cleaner, which avoids turbulence in the inlet region and in the region of the air outlet, and provides an increased volume flow while reducing the noise.
  • the vacuum cleaner according to the invention comprises a centrifugal separator of an air guide means, wherein the air guide means is a surface which is generated by screwing a space curve about the longitudinal axis of the centrifugal separator and at the end of the surface has an edge which has an inner and an outer corner, wherein the outer corner has an axial position in the longitudinal direction of the axis of the centrifugal separator and the outer corner in a radial angular range orthogonal to the axis of the separating space between is plus and minus 15 degrees, wherein the zero position of the angular range is formed from a radius of the separation space and from an intersection, which represents the transition of the air inlet channel in the separation chamber, which faces the screwing of the space curve.
  • Both cyclone and cyclone separators are to be regarded as centrifugal separators, centrifugal forces acting on the particles in the centrifugal force separator and accelerating them radially outward.
  • centrifugal separators are used in particular in so-called bagless vacuum cleaners.
  • air guidance means those devices are to be considered, which the incoming air from its original flow direction into another Distract flow direction. With a screwing of a space curve around a fixed direction, a helix is generated and its formed surface represents the air guide means.
  • the air guide means can start on the one hand on a boundary surface of the separation chamber and ends on the other hand in the separation chamber with an edge projecting into the free space.
  • the trailing edge of the air guide means may form an inner and outer corner with the inwardly adjacent surfaces of the separation space.
  • the outer corner is located at the lateral boundary of the air inlet passage so that, with a right-handed air guide means, wherein the screw rotates away from the air inlet and to the ejection, the corner on the left side and a left-hand air guide means on the right side the air inlet is arranged.
  • An angle of 360 degrees makes a full turn.
  • the air duct may end in the region of the air inlet. It can thus be achieved that the incoming air and the rotating air are located at the entry point in spaced-apart planes and flow largely unaffected from each other, or almost without mutual collision.
  • the air inlet channel opens in the vicinity of a separating surface on one side final boundary surface in the separation chamber.
  • the outer corner on an axial position, of one of the boundary surface (23) nearest the mouth of the Lufeinlasskanals (3) in the separation chamber (5) in the longitudinal direction of the axis of the centrifugal separator by 0.5 to 1.5 times the height of the mouth of the air inlet channel is spaced.
  • the term height is the extent of the mouth defined in the axial direction.
  • the axial position of the outer corner in the longitudinal direction of the axis of the centrifugal separator may be about two-thirds to about the maximum height of the air inlet channel.
  • the air inlet channel preferably opens tangentially into the separation chamber.
  • the air inlet can be tangential to an air flow in the centrifugal separator and the air guide means deflect the incoming air into a perpendicular to the air inlet protruding helix.
  • the air can be converted into a preferably screw-shaped or spiral rotational movement with largely avoiding swirling at the point of entry and with as little resistance as possible.
  • the outer corner of the air guide means is located on the boundary of the air inlet channel, which represents the transition of the air inlet channel in the separation chamber and which faces the screwing of the space curve in the separation space.
  • the air inlet channel can thereby be continued into the separation chamber, without colliding with a rotating air flow. As a result, especially turbulences and noises in the middle and higher audible frequency range can be avoided.
  • the edge of the air guide means terminates in the separation chamber or is connected to a cover which closes a space between the air guide and the air inlet side boundary surface of the separation chamber.
  • the edge may be connected to a boundary wall, which protect a dead space below the air guide means, so aligned to the air inlet side boundary surface, against dust deposits.
  • the boundary surface together with the air inlet channel may form a continuous wall which extends the lateral area of the air inlet channel into the separation space.
  • the outer and the inner corner of the air ducting means is located on a line of an obliquely cut cylinder or conic section.
  • the two corners are located on a spatially arranged secant in a cylinder or cone.
  • the outer and inner corners of the air guide means lie on a straight line which lies on a plane which intersects the centrifugal separator orthogonal to the axis of the centrifugal separator.
  • the two corners can thereby lie at different heights, wherein superimposed swirl effects can be achieved in conjunction with the curve lying between the two corners and the concomitant surface in the direction of the air flow, which allow an improved separation efficiency.
  • the edge forms a straight line or a convex or concave curve.
  • a convex curve is an outwardly, ie curved into the separation chamber, under a concave curve is to be understood inwardly, ie curved away from the discharge side shape.
  • the term curve includes symmetric as well as subsections of symmetric and asymmetric geometries.
  • a straight line can be converted into a tool shape with simple means. Curves may have the advantage that at the radial transitions from the air guide means to the inner boundary walls of the centrifugal separator radii are present, which advantageously avoid areas with turbulence and dust deposits.
  • the outer and the inner corner are arranged around the axis of the centrifugal separator after a maximum of one complete revolution of the air guiding means.
  • the air guiding means can guide the air for a maximum of one revolution about the radial axis and thereby unfold the air flow with the dust particles without a limiting channel formation.
  • a limiting channel may be disadvantageous in that as large, heavy particles only half a revolution, small, light particles, however, require around three revolutions to reach the ejection into the dust collector.
  • an air guide means which extends a maximum of one revolution, it can be achieved that act on the different particles their own radial and axial forces and accelerations after a maximum of one revolution and are not slowed down in the radial direction réelleelleder air guide means.
  • the air guide means may extend over a third of a revolution, preferably at the end of a revolution.
  • the invention further development is preferably provided that connects to the air guide means a plateau.
  • air flowing in from the air inlet channel can thereby be prevented from the rotating spiral or screw movement.
  • it can be achieved that, at the end of the air duct, the helical or spiral air in the separation chamber can be safely guided over the inflowing air which lies deeper in the plane.
  • turbulences of the two air streams which are almost perpendicular to one another, can advantageously be avoided.
  • the plateau no longer counts as an air-guiding means and its pitch is substantially less than the pitch of the air-guiding means.
  • the slope of the plateau is approximately zero.
  • the air guide means formed integrally with the centrifugal separator or constitutes a separate component of the centrifugal separator.
  • a one-piece design of the air guide means together with the inner wall of the centrifugal separator allow a simple tool design and easy assembly assembly.
  • With a separate component design of the air guide means can advantageously more complex geometries are displayed.
  • Wear-resistant or differently colored materials are used.
  • the air guide means is arranged on a removable or movable housing part of the centrifugal separator.
  • the air guide means may be arranged on a removable or movable housing part of the centrifugal separator.

  • the incoming air over the full available width, ie in the radial direction are detected by the air guide means and the particles are accelerated to the outside and receive a spiral or screw movement.
  • the air guide means extends in the radial direction away from the axis of the centrifugal separator and has a distance to the inner wall of the centrifugal separator.
  • Small light particles take more turns to reach the ejection window than large, heavy particles.
  • the air guiding means are advantageously at a distance from the inner wall of the separating space, their particular radial centrifugal forces, as well as axial accelerations caused by the screwing movement of the air, can act especially on the different weighty particles. Even with a short residence time of the dust-laden air in the region of the air duct, this effect can be achieved. Particularly small particles can thereby experience a safe unchecked acceleration.
  • an oblique ejection surface is arranged in an advantageous manner. Particles which are located on the part of the ejection surface which ascends toward the ejection can be ejected safely into the dust collecting container at the outlet opening.
  • turbulences in the region of the air outlet, which is connected to the separation chamber via a dip tube, can thereby be avoided.
  • An oblique ejection surface means a plane which is not oriented orthogonally to the axis of the centrifugal separator, that is to say at an angle.

  • an air guide means 8 in the form of a surface 9 is provided starting from the lower boundary surface 23 of the separation chamber 5, which results from continuous screwing 10 of a radius 14 of a longitudinal axis 11 of the separation chamber 4 about this longitudinal axis 11.
