Definitions

  • the subject of the present invention is a vacuum cleaner separator for high-speed vacuum cleaner motor, preferably a household vacuum cleaner.
  • a technical problem solved by the present invention is how to construct such vacuum cleaner separator for high-speed vacuum cleaner motor that will reach the anticipated exclusion of dust particles under planned operating vacuum and would have decreased dimensions and an increased number of revolutions (30,000 to 45,000 rev/min) of the entire vacuum unit including the separator.
  • Price efficient materials and manufacturing procedures should be used, wherein the new constructions should provide for the balancing of rotating parts due to anticipated high revolutions in a simple and quality way.
  • the vacuuming arrangement should be simple and proper sealing should be ensured between the rotating separator and the standing housing.
  • the product should be of high quality and have a long life span as well as having a market acceptable price.
  • the design of the separator should allow it to be independently placed on a shaft or be manufactured integrally with a turbine wheel.
  • EP 1 261 269 (Hyla Proizvodnja, razvoj in trgovina d.o.o.) discloses an invention of a separator consisting of several axially composed segments, in which blades are arranged on the circumference in the shape of an airplane wing. All blades are positioned equally with respect to the housing. The construction is mechanically relatively stiff and adequate also for high rotation frequencies, because the blades constituted of segments are relatively short.
  • This embodiment allows for balancing of the separator on the shaft, wherein the fan cover is installed subsequently.
  • a drawback of the described embodiment is a complicated construction of as many as six constituent parts, which results in high production costs.
  • Sealing between the separator and the housing is effected through air counter-flow created by a turbine wheel in co-operation with air ducts on the internal side of the fan cover.
  • a drawback of sealing is huge aerodynamic losses, which are a result of the fact that part of energy on the turbine wheel is used for the return flow of a part of air jet back to a fluid bath.
  • the separator of the invention which is characterised by consisting of a revolved surface core having a coaxially running drilled hole to receive a shaft of the electric motor and which extends at a free end in a cone-like shape, wherein in the vicinity of the opposite part, i.e. adjacent to the turbine wheel, it is provided with a ring connecting the blades and acting as a dynamic sealing ring with respect to the housing.
  • Blades are arranged along the entire height on the revolved surface core.
  • the blades are characterised by their external free edge running on the surface plane of an apparent truncated cone, whose larger diameter lies near the turbine wheel and the smallest diameter is at the opposite end, wherein their internal edge lies on the described revolved surface core.
  • Such design achieves air flow through the separator due to vacuum created by the turbine wheel, so that part of the air jet in the vicinity of the turbine wheel due to higher centrifugal force provided to it by a section of the separator directs radially outwards at the slot between the ring on the separator and the housing of the suction unit, so that a relatively small air flow is achieved with respect to the remaining changing conditions in direction towards the turbine wheel or in opposite direction.
  • the air flowing through the slot is cleaned and does not diminish the quality of vacuuming.
  • the energy transfers to the air jet to make it pass through the separator; in the second embodiment it flows through the turbine wheel.
  • the path of said air jet is considerably shorter and has less obstacles regardless of its direction. Energy consumption is therefore considerably lower in both cases in comparison with the solutions stated in the prior art.
  • a final result is a greater yield of the apparatus as such.
  • Air flow is present within the separator and flows from the area of the separator with higher pressure through slots between blades to the interior of the separator, where it flows parallel to the blades from the bottom of the separator towards the output from the separator in direction towards the turbine, which creates air vacuum.
  • the pressure and the speed of air flow within the separator should therefore be arranged in a way that the vacuum of the suctioned air changes equally from the bottom of the separator to the output air opening so that no losses occur due to differences in vacuum due to a harmful mutual influence.
  • the described design of the separator provides for a dynamic balancing of the assembly, which consists of a pre-balanced rotor of the electric motor, a turbine wheel arranged on the same shaft and a separator, wherein such dynamic balancing is carried out, when the assembly is positioned in its operating position. After the final balancing, the last assembling intervention is needed, i.e. positioning of a cover of the turbine wheel. The number of assembling steps of a vacuuming unit is herewith considerably decreased.
  • a vacuum cleaner separator 1 for vacuum cleaner high-speed motor preferably for a household vacuum cleaner consists of a central revolved surface portion 2 comprising a cylindrical segment 3 extending on the side of a turbine wheel 4 on at least one half of the length of said separator 1 and a segment 5 formed as a lateral surface area with said segment 3 of the coaxially running truncated cone, which is in contact with said segment 3 with the side having a smaller diameter.
  • Within said cylindrical segment 5 there is a coaxially running drilled hole 6 to receive an shaft 7 of an electric motor 8.
  • the lateral surface area of said revolved surface portion 2 is provided with blades extending radially and shaped in their cross-section in a known way in order to reach a good transfer of air jet between them, said air jet being created by said turbine wheel 4 by vacuum.
  • a special feature is that external edges 10 of said blades 9 are arranged on an apparent lateral surface area of the truncated cone, whose larger diameter lies adjacent to said turbine wheel 4.
  • the width of said blades 9 varies as a function of the mentioned shape of said revolved surface portion 2 and the extension of said external edges 10.
  • the optimal laminar flow of the air jet between said blades is achieved, which contributes to a good yield of the apparatus as such.
  • Said blades 9 are linked with each other on the side of said turbine wheel 4 by a sealing ring 11, which provides said blades 9 with sufficient stiffness needed for the expected high revolutions of said separator 1. Further, said ring 11 should lie within an opening 12 of a casing 13 of said turbine wheel 4 in a way that it forms a gap 14 with its external surface and said opening 12. Said gap 14 allows for a smooth positioning of said casing 15 only after all rotating parts have been balanced and assembled to an integral unit.
  • the geometry of said external edges 10 of said blades 9 is such that they lie on the lateral surface area of the apparent truncated cone, which provides such centrifugal force to a part of the air jet in the vicinity of said turbine wheel, that the force of vacuum is surpassed, which vacuum is created by said turbine wheel 4, so that this part of the jet is directed radially outwards past said gap 14.
  • the pressure of the air jet near said gap 14 can vary due to a possible and expected variation in air resistance of the air jet at the output side of the air jet from the vacuum cleaner.
  • the vacuuming unit with the separator of the invention is intended to be integrated into a vacuum cleaner with or without an air filter at the output side of the air jet.
  • the air jet through said gap 14 is oriented through said gap 14 towards said turbine wheel 4.
  • the air flowing through said gap 14 is part of the radially outwards oriented air jet directed by said separator 1. This air is already cleaned and does not lower the quality of the basic operation of the vacuum cleaner.
  • blades 15 may be provided in the internal area of the cone section 3, i.e. on the free front side of said revolved surface section 2 , said blades 15 contributing to the formation of as homogeneous water mist as possible in the sense of equal size of individual water particles, which ensures an efficient reception of dust particles in an individual water particle. This is one of the basic conditions for efficient vacuuming.
  • the number of blades 15 preferably equals the number of blades 9.
  • the blades 9 and 15 are arranged in a way to merge in said section 3 at a smallest possible mutual distance, wherein such construction allows for a smaller thickness of the wall of said section 3 and thus meets a requirement for a desired low weight of the separator.
  • the areas of said blades 9 can be machined at the free section of said separator 1, i.e. opposite said turbine wheel 4.
  • Said blades 9 can be provided with a chamfer 17 in this section, which can be slanting or rounded.
